I then measured the max response throughput using a +queryperf-like tool. In both cases Q2 is about 28% of Q1 (I'm not +showing specific numbers to avoid unnecessary discussion about +specific performance of existing servers; it's out of scope of this +memo). Using Q2 = 0.28*Q1, above equation with 90% cache hit rate +will be: A = 0.9 * 0.28 / (0.9*0.28 + 0.1) = 0.716.

Record cache + +Conceptually, any recursive resolver (with cache) implementation would +have cache for RRs (or RRsets in the modern version of protocol) given +in responses to its external queries. In BIND 9, it's called the +"cached DB", using an in-memory rbt-like tree. unbound calls it +"rrset cache", which is implemented as a hash table. + +2. Delegation cache + +Recursive server implementations would also have cache to determine +the deepest zone cut for a given query name in the recursion process. +Neither BIND 9 nor unbound has a separate cache for this purpose; +basically they try to find an NR RRset from the "record cache" whose +owner name best matches the given query name. + +3. Remote server cache + +In addition, a recursive server implementation may maintain a cache +for information of remote authoritative servers. Both BIND 9 and +unbound conceptually have this type of cache, although there are some +non-negligible differences in details. BIND 9's implementation of +this cache is called ADB. Its a hash table whose key is domain name, +and each entry stores corresponding IPv6/v4 addresses; another data +structure for each address stores averaged RTT for the address, +lameness information, EDNS availability, etc. unbound's +implementation is called "infrastructure cache". It's a hash table +keyed with IP addresses whose entries store similar information as +that in BIND 9's per address ADB entry. In unbound a remote server's +address must be determined by looking up the record cache (rrset cache +in unbound terminology); unlike BIND 9's ADB, there's no direct +shortcut from a server's domain name to IP addresses. + +4. Full response cache + +unbound has an additional cache layer, called the "message cache". +It's a hash table whose hash key is query parameter (essentially qname +and type) and entry is a sequence to record (rrset) cache entries. +This sequence constructs a complete response to the corresponding +query, so it would help optimize building a response message skipping +the record cache for each section (answer/authority/additional) of the +response message. PowerDNS recursor has (seemingly) the same concept +called "packet cache" (but I don't know its implementation details +very much). + +BIND 9 doesn't have this type of cache; it always looks into the +record cache to build a complete response to a given query. + +Miscellaneous General Requirements +---------------------------------- + +- Minimize contention between threads (if threaded) +- Cache purge policy: normally only a very small part of cached DNS + information will be reused, and those reused are very heavily + reused. So LRU-like algorithm should generally work well, but we'll + also need to honor DNS TTL. + +Random Ideas for BIND 10 +------------------------ + +Below are specific random ideas for BIND 10. Some are based on +experimental results with reasonably realistic data; some others are +mostly a guess. + +1. Fully rendered response cache + +Some real world query samples show that a very small portion of entire +queries are very popular and queried very often and many times; the +rest is rarely reused, if any. Two different data sets show top +10,000 queries would cover around 80% of total queries, regardless +of the size of the total queries. This suggests an idea of having a +small, highly optimized full response cache. + +I tried this idea in the jinmei-l1cache branch. It's a hash table +keyed with a tuple of query name and type whose entry stores fully +rendered, wire-format response image (answer section only, assuming +the "minimal-responses" option). It also maintains offsets to each +RR, so it can easily update TTLs when necessary or rotate RRs if +optionally requested. If neither TTL adjustment nor RR rotation is +required, query handling is just to lookup the hash table and copy the +pre-rendered data. Experimental benchmark showed it ran vary fast; +more than 4 times faster than BIND 9, and even much faster than other +implementations that have full response cache (although, as usual, the +comparison is not entirely fair). + +Also, the cache size is quite small; the run time memory footprint of +this server process was just about 5MB. So, I think it's reasonable +to have each process/thread have their own copy of this cache to +completely eliminate contention. Also, if we can keep the cache size +this small, it would be easier to dump it to a file on shutdown and +reuse it on restart. This will be quite effective (if the downtime is +reasonably short) because the cached data are expected to be highly +popular. + +2. Record cache + +For the normal record cache, I don't have a particular idea beyond +something obvious, like a hash table to map from query parameters to +corresponding RRset (or negative information). But I guess this cache +should be shared by multiple threads. That will help reconstruct the +full response cache data on TTL expiration more efficiently. And, if +shared, the data structure should be chosen so that contention +overhead can be minimized. In general, I guess something like hash +tables is more suitable than tree-like structure in that sense. + +There's other points to discuss for this cache related to other types +of cache (see below). + +3. Separate delegation cache + +One thing I'm guessing is that it may make sense if we have a separate +cache structure for delegation data. It's conceptually a set of NS +RRs so we can identify the best (longest) matching one for a given +query name. + +Analysis of some sets of query data showed the vast majority of +end client's queries are for A and AAAA (not surprisingly). So, even +if we separate this cache from the record cache, the additional +overhead (both for memory and fetch) will probably (hopefully) be +marginal. Separating caches will also help reduce contention between +threads. It *might* also help improve lookup performance because this +can be optimized for longest match search. + +4. Remote server cache without involving the record cache + +Likewise, it may make sense to maintain the remote server cache +separately from the record cache. I guess these AAAA and A records +are rarely the queried by end clients, so, like the case of delegation +cache it's possible that the data sets are mostly disjoint. Also, for +this purpose the RRsets don't have to have higher trust rank (per +RFC2181 5.4.1): glue or additional are okay, and, by separating these +from the record cache, we can avoid accidental promotion of these data +to trustworthy answers and returning them to clients (BIND 9 had this +type of bugs before). + +Custom vs Existing Library (STL etc) +------------------------------------ + +It may have to be discussed, but I guess in many cases we end up +introducing custom implementation because these caches should be +highly performance sensitive, directly related our core business, and +also have to be memory efficient. But in some sub components we may +be able to benefit from existing generic libraries. -- cgit v1.2.3 From e9799d37bb8a0d145d0080c8ac93781c08f150e6 Mon Sep 17 00:00:00 2001 From: Michal 'vorner' Vaner Date: Thu, 7 Mar 2013 11:22:45 +0100 Subject: [2775] Diagram of how resolution works --- doc/design/resolver/01-scaling-across-cores | 41 +++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/doc/design/resolver/01-scaling-across-cores b/doc/design/resolver/01-scaling-across-cores index 8fc376be5e..b4c4e299b8 100644 --- a/doc/design/resolver/01-scaling-across-cores +++ b/doc/design/resolver/01-scaling-across-cores @@ -19,3 +19,44 @@ d.

We further group them and + each level handles less queries from each process, so they can keep up. + However, with each level, we add some overhead to do another lookup. +Segmented cache:: + We have several caches of the same level, in parallel. When we would ask a + cache, we hash the query and decide which cache to ask by the hash. Only that + cache would have that answer if any and each could run in a separate process. + The only problem is, could there be a pattern of queries that would skew to + use only one cache while the rest would be idle? +Shared cache access:: + A cache would be accessed by multiple processes/threads. See below for + details, but there's a risk of lock contention on the cache (it depends on + the data structure). + +Upstream queries +~~~~~~~~~~~~~~~~ + +Before doing an upstream query, we look into the cache to ensure we don't have +the information yet. When we get the answer, we want to update the cache. + +This suggests the upstream queries are tightly coupled with the cache. Now, +when we have several cache processes/threads, each can have some set of opened +sockets which are not shared with other caches to do the lookups. This way we +can avoid locking the upstream network communication. + +Also, we can have three conceptual states for data in cache, and act +differently when it is requested. + +Present:: + If it is available, in positive or negative version, we just provide the + answer right away. +Not present:: + The continuation of processing is queued somehow (blocked/callback is + stored/whatever). An upstream query is sent and we get to the next state. +Waiting for answer:: + If another query for the same thing arrives, we just queue it the same way + and keep waiting. When the answer comes, all the queued tasks are resumed. + If the TTL > 0, we store the answer and set it to ``present''. + +We want to do aggregation of upstream queries anyway, using cache for it saves +some more processing and possibly locks. + +Multiple parallel queries +------------------------- + +It seems obvious we can't afford to have a thread or process for each +outstanding query. We need to handle multiple queries in each one at any given +time. + +Coroutines +~~~~~~~~~~ + +The OS-level threads might be too expensive, but coroutines might be cheap +enough. In that way, we could still write a code that would be easy to read, +but limit the number of OS threads to reasonable number. + +In this model, when a query comes, a new coroutine/user-level thread is created +for it. We use special reads and writes whenever there's an operation that +could block. These reads and writes would internally schedule the operation +and switch to another coroutine (if there's any ready to be executed). + +Each thread/process maintains its own set of coroutines and they do not +migrate. This way, the queue of coroutines is kept lock-less, as well as any +private caches. Only the shared caches are protected by a lock. + +[NOTE] +The `coro` unit we have in the current code is *not* considered a coroutine +library here. We would need a coroutine library where we have real stack for +each coroutine and we switch the stacks on coroutine switch. That is possible +with reasonable amount of dark magic (see `ucontext.h`, for example, but there +are surely some higher-level libraries for that). + +There are some trouble with multiple coroutines waiting on the same event, like +the same upstream query (possibly even coroutines from different threads), but +it should be possible to solve. + +Event-based +~~~~~~~~~~~ + +We use events (`asio` and stuff) for writing it. Each outstanding query is an +object with some callbacks on it. When we would do a possibly blocking +operation, we schedule a callback to happen once the operation finishes. + +This is more lightweight than the coroutines (the query objects will be smaller +than the stacks for coroutines), but it is harder to write and read for. + +[NOTE] +Do not consider cross-breeding the models. That leads to space-time distortions +and brain damage. Implementing one on top of other is OK, but mixing it in the +same bit of code is a way do madhouse. + +Landlords and peasants +~~~~~~~~~~~~~~~~~~~~~~ + +In both the coroutines and event-based models, the cache and other shared +things are easier to imagine as objects the working threads fight over to hold +for a short while. In this model, it is easier to imagine each such shared +object as something owned by a landlord that doesn't let anyone else on it, +but you can send requests to him. + +A query is an object once again, with some kind of state machine. + +Then there are two kinds of threads. The peasants are just to do the heavy +work. There's a global work-queue for peasants. Once a peasant is idle, it +comes to the queue and picks up a handful of queries from there. It does as +much each the query as possible without requiring any shared resource. + +The other kind, the landlords, have a resource to watch over each. So we would +have a cache (or several parts of cache), the sockets for accepting queries and +answering them, possibly more. Each of these would have a separate landlord +thread and a queue of tasks to do on the resource (look up something, send an +answer...). + +Similarly, the landlord would take a handful of tasks from its queue and start +handling them. It would possibly produce some more tasks for the peasants. + +The point here is, all the synchronisation is done on the queues, not on the +shared resources themselves. And, we would append to a queues once the whole +batch was completed. By tweaking the size of the batch, we could balance the +lock contention, throughput and RTT. The append/remove would be a quick +operation, and the cost of locks would amortize in the larger amount of queries +handled per one lock operation. + +The possible downside is, a query needs to travel across several threads during +its lifetime. It might turn out it is faster to move the query between cores +than accessing the cache from several threads, since it is smaller, but it +might be slower as well. + +It would be critical to make some kind of queue that is fast to append to and +fast to take out first n items. Also, the tasks in the queues can be just +abstract `boost::function` functors, and each worker would just +iterate through the queue, calling each functor.

Remote clients there are two + mechanisms that can be used here. The first one is based on + interface-id options. While forwarding client's message, relays may + insert interface-id option that identifies the interface on which the + client message was received on. Some relays allow configuration of + that parameter, but it is sometimes hardcoded. This may range from + very simple (e.g. "vlan100") to very cryptic. One example used by real + hardware was "ISAM144|299|ipv6|nt:vp:1:110"). This may seem + meaningless, but that information is sufficient for its + purpose. Server may use it to select appropriate subnet and the relay + will know which interface to use for response transmission when it + gets that value back. This value must be unique in the whole + network. Server configuration must match whatever values are inserted + by the relays. + + + The second way in which server may pick the proper subnet is by using + linkaddr field in the RELAY_FORW message. Name of this field is somewhat + misleading. It does not contain link-layer address, but an address that + is used to identify a link. This typically is a global address. Kea + server checks if that address belongs to any defined subnet6. If it does, + that subnet is selected for client's request. + + + It should be noted that "interface" that defines which local network + interface can be used to access a given subnet and "interface-id" that + specify the content of the interface-id option used by relays are mutually + exclusive. A subnet cannot be both reachable locally (direct traffic) and + via relays (remote traffic). Specifying both is a configuration error and + Kea server will refuse such configuration. + + + To specify interface-id with value "vlan123", the following commands can + be used: + +> config add Dhcp6/subnet6 +> config set Dhcp6/subnet6[0]/subnet "2001:db8:beef::/48" +> config set Dhcp6/subnet6[0]/pool [ "2001:db8:beef::/48" ] +> config set Dhcp6/subnet6[0]/interface-id "vland123" +> config commit

Each relay receives a message +on a client facing interface, encapsulates it into RELAY_MSG option +and sends as RELAY_FORW message towards the server (or the next relay, +which is closer to the server). This procedure can be repeated up to +32 times. Kea is able to support up to 32 relays. Each traversed relay +may add certain options. The most obvious example is interface-id +option, but there may be other options as well. Each relay may add such +an option, regardless of whether other relays added it before. Thanks +to encapsulation, those options are separated and it is possible to +differentiate which relay inserted specific instance of an option. + +Interface-id is used to identify a subnet (or interface) the original message +came from and is used for that purpose on two occasions. First, the server +uses the interface-id included by the first relay (the one closest to +the client) to select appropriate subnet for a given request. Server includes +that interface-id in its copy, when sending data back to the client. +This will be used by the relay to choose proper interface when forwarding +response towards the client. + +Pkt6 class has a public Pkt6::relay_info_ field, which is of type Pkt6::RelayInfo. +This is a simple structure that represents the information in each RELAY_FORW +or RELAY_REPL message. It is important to understand the order in which +the data appear here. Consider the following network: + +\verbatim +client-------relay1-----relay2-----relay3----server +\endverbatim + +Client will transmit SOLICIT message. Relay1 will forward it as +RELAY_FORW with SOLICIT in it. Relay2 forward it as RELAY_FORW with +RELAY_FORW with SOLICIT in it. Finally the third relay will add yet +another RELAY_FORW around it. The server will parse the packet and +create Pkt6 object for it. Its relay_info_ will have 3 +elements. Packet parsing is done in reverse order, compare to the +order the packet traversed in the network. The first element +(relay_info_[0]) will represent relay3 information (the "last" relay or +in other words the one closest to the server). The second element +will represent relay2. The third element (relay_info_[2]) will represent +the first relay (relay1) or in other words the one closest to the client. + +Packets sent by the server must maintain the same encapsulation order. +This is easy to do - just copy data from client's message object into +server's response object.

As long as + the method names and corresponding wrapper function (such as + ZoneWriter_cleanup) are correct you shouldn't have to edit this part + (and they would be normally correct, unless the guessed method name + conversion was needed). + + The rest of the content is a sequence of constant C-string variables. + Usually the first variable corresponds to the class description, and + the rest are method descriptions (note that ZoneWriter_install_doc + is referenced from the ifdef-ed block).

Instead of +altering the BIND 10 source code, they write functions that are compiled +and linked into a shared library. The library is specified in the BIND 10 +configuration database and run time, BIND 10 dynamically loads the library +into its address space. At various points in the processing, the server +"calls out" to functions in the library, passing to them the data is it +currently working on. They can examine and modify the data as required. + +The document @ref hooksDevelopersGuide describes how to write a library +that interfaces into a BIND 10 component. This guide describes how to +write or modify a BIND 10 component so that it can load a shared library +and call out to functions in it. + +@subsection hooksComponentTerminology Terminology + +In the remainder of this guide, the following terminology is used: + +- Hook/Hook Point - used interchageably, this is a point in the code at +which a call to user-written functions is made. Each hook has a name and +each hook can have any number (including 0) of user-written functions +attached to it. + +- Callout - a user-written function called by the server at a hook +point. This is so-named because the server "calls out" to the library +to execute a user-written function. + +- Component - a BIND 10 process, e.g. the authoritative server or the +DHCPv4 server. + +- User code/user library - non-BIND 10 code that is compiled into a +shared library and loaded by BIND 10 into its address space. Multiple +user libraries can be loaded at the same time, each containing callouts for +the same hooks. The hooks framework calls these libraries one after the +other. (See the document @hooksDevelopersGuide for more details.) + +@subsection hooksComponentLanguages Languages + +The core of BIND 10 is written in C++ with some parts in Python. While it is +the intention to provide the hooks framework for all languages, the initial +versions are for C++. All examples in this guide are in that language. + +@section hooksComponentBasicIdeas Basic Ideas + +From the point of view of the component author, the basic ideas of the hooks +framework are quite simple: + +- The hook points need to be defined. + +- At each hook point, the component needs to: + - copy data into the object used to pass information to the callout. + - call the callout. + - copy data back from the object used to exchange information. + - take action based on information returned. + +Of course, to set up the system the libraries need to be loaded in the first +place. The component also needs to: + +- Define the configuration item that specifies the user libraries for this +component. + +- Handle configuration changes and load/unload the user libraries. + +The following sections will describe these tasks in more detail. + +@section hooksComponentDefinition Defining the Hook Points + +Before any other action takes place, the hook points in the code need to be +defined. Each hook point has a name that must be unique amongst all hook +points for the server, and the first step is to register those names. The +naming is done using the static method isc::hooks::HooksManager::registerHook(): + +@code + +#include + : + int example_index = HooksManager::registerHook("manager"); +@endcode + +The name of the hooks is passed as the sole argument to the +HooksManager::registerHook() method. The value returned is the index of that +hook point and should be retained - it is needed to call the hook. + +All hooks used by the component must be registered before the component +starts operations. + +@subsection hooksComponentHookNames Hook Names + +Hook names are strings and in principle, any string can be used as the +name of a hook, even one containing spaces and non-printable characters. +However, the following guidelines should be observed: + +- The names context_create and context_destroy are reserved to +the hooks system and are automatically registered: an attempt to register +one of these will lead to a isc::hooks::DuplicateHook exception being thrown. + +- The hook name should be a valid function name in C. If a user gives a +callout the same name as one of the hooks, the hooks framework will +automatically load that callout and attach it to the hook: the user does not +have to explicitly register it. TBD: do we still want this given +the possibility of confusion with functions in system libraries? + +- The hook name should not conflict with the name of a function in any of +the system libraries (e.g. naming a hook "sqrt" could lead to the +square-root function in the system's maths library being attached to the hook +as a callout). + +- Although hook names can be in any case (including mixed case), the BIND 10 +convention is that they are lower-case. + +@subsection hooksComponentAutomaticRegistration Automatic Registration of Hooks + +In some components, it may be convenient to set up a separate +initialization function that registers all hooks. For others, it may +be more convenient for each module within the component to perform its +own initialization. Since the HooksManager object is a singleton and +is created when first requested, a useful trick is to automatically +register the hooks when the module is loaded. + +This technique involves declaring an object outside of any execution +unit in the module. When the module is loaded, the object's constructor +is run. By placing the hook registration calls in the constructor, +the hooks in the module are defined at load time, before any function in +the module is run. The code for such an initialization sequence would +be similar to: + +@code +#include + +namespace { + +// Declare structure to perform initialization and store the hook indexes. +// +struct MyHooks { + int pkt_rcvd; // Packet received + int pkt_sent; // Packet sent + + // Constructor + MyHooks() { + pkt_rcvd = HooksManager::registerHook("pkt_rcvd"); + pkt_sent = HooksManager::registerHook("pkt_sent"); + } +}; + +// Instantiate a "Hooks" object. The constructor is run when the module is +// loaded and so the hook indexes will be defined before any method in this +// module is called. +Hooks hooks; + +} // Anonymous namespace + +void Someclass::someFunction() { + : + // Check if any callouts are defined on the pkt_rcvd hook. + if (HooksManager::calloutPresent(hooks.pkt_rcvd)) { + : + } + : +} +@endcode + +@section hooksComponentCallingCallouts Calling Callouts on a Hook + +@subsection hooksComponentArgument The Callout Handle + +Before describing how to call user code at a hook point, we must first consider +how to pass data to it. + +Each user callout has the signature: +@code +int callout_name(CalloutHandle& handle); +@endcode + +The isc::hooks::CalloutHandle object is the object used to pass data to +and from the callout. This holds the data as a set of name/value pairs, +each pair being considered an argument to the callout. + +Two methods are provided to get and set the arguments passed to +the callout called (naturally enough) getArgument and SetArgument. +Their usage is illustrated by the following code snippets. + +@code + int count = 10; + boost::shared_ptr pktptr = ... // Set to appropriate value + + // Assume that "handle" has been created + handle.setArgument("data_count", count); + handle.setArgument("inpacket", pktptr); + + // Call the hook code... + ... + + // Retrieve the modified values + handle.getArgument("data_count", count); + handle.getArgument("inpacket", pktptr); +@endcode + +As can be seen "getArgument" is used to retrieve data from the +isc::hooks::CalloutHandle, and setArgument used to put data into it. +If a callout wishes to alter data and pass it back to the server, +it should retrieve the data with getArgument, modify it, and call +setArgument to send it back. + +There are a couple points to be aware of: + +- The data type of the variable in the call to getArgument must +match the data type of the variable passed to the corresponding +setArgument exactly: using what would normally be considered +to be a "compatible" type is not enough. For example, if the callout +passed an argument back to the component as an "int" and the component +attempted to retrieve it as a "long", an exception would be thrown even +though any value that can be stored in an "int" will fit into a "long". +This restriction also applies the "const" attribute but only as applied to +data pointed to by pointers, e.g. if an argument is defined as a "char*", +an exception will be thrown if an attempt is made to retrieve it into +a variable of type "const char*". (However, if an argument is set as a +"const int", it can be retrieved into an "int".) The documentation of +each hook point should detail the exact data type of each argument. + +- If a pointer to an object is passed to a callout (either a "raw" +pointer, or a boost smart pointer (as in the example above), and the +underlying object is altered through that pointer, the change will be +reflected in the component even if the callout makes no call to setArgument. +This can be avoided by passing a pointer to a "const" object. + +@subsection hooksComponentGettingHandle Getting the Callout Handle + +The CalloutHandle object is linked to the loaded libraries +for lifetime reasons (described below). Components +should retrieve a isc::hooks::CalloutHandle using +isc::hooks::HooksManager::createCalloutHandle(): +@code + CalloutHandlePtr handle = HooksManager::createCalloutHandle(); +@endcode +(isc::hooks::CalloutHandlePtr is a typedef for a boost shared pointer to a +CalloutHandle.) The CalloutHandle so retrieved may be used for as +long as the libraries are loaded. +@code + handle.reset(); +@endcode +... or by letting the handle object go out of scope. The actual deletion +occurs when the CallHandle's reference count goes to zero. (The +current version of the hooks framework does not maintain any other +pointer to the returned CalloutHandle, so it gets destroyed when the +shared pointer to it is cleared or destroyed. However, this may change +in a future version.) + +@subsection hooksComponentCallingCallout Calling the Callout + +Calling the callout is a simple matter of executing the +isc::hooks::HooksManager::callCallouts() method for the hook index in +question. For example, with the hook index pkt_sent defined as above, +the hook can be executed by: +@code + HooksManager::callCallouts(pkt_rcvd, *handle); +@endcode +... where "*handle" is a reference (note: not a pointer) to the +isc::hooks::CalloutHandle object holding the arguments. No status code +is returned. If a component needs to get data returned, it should define +an argument through which the callout can do so. + +Actually, the statement "no status code is returned" is not strictly true. At +many hooks, the following logic applies: +@code +call hook_code +if (hook_code has not performed an action) { + perform the action +} +@endcode +For example, in a DHCP server an address should be allocated for a client. +The DHCP server does that by default, but the hook code may want to override +it in some situations. + +As this logic is so common, the CalloutHandle includes a "skip" flag. This +is a boolean flag that can be set by the callout to pass a basic yes/no +response to the component. Its use is illustrated by the following code +snippet: +@code +// Set up arguments for lease assignment +handle->setArgument("query", query); +handle->setArgument("response", response); +HooksManager::callCallouts(lease_hook_index, *handle); +if (! handle->getSkip()) { + // Skip flag not set, do the address allocation + : +} +@endcode +SHOULD WE GET RID OF THE SKIP FLAG AND WHERE APPROPRIATE, SIGNAL SUCH +PROCESSING THROUGH AN ARGUMENT? + +@subsubsection hooksComponentConditionalCallout Conditionally Calling Hook Callouts + +Most hooks in a server will not have callouts attached to them. To avoid the +overhead of setting up arguments in the CalloutHandle, a component can +check for callouts before doing that processing. The +isc::hooks::HooksManager::calloutsPresent() method performs this check. +Taking the index of a hook as its sole argument, it returns true if there +are any callouts attached to the hook and false otherwise. + +With this check, the above example can be modified to: +@code +if (HooksManager::calloutsPresent(lease_hook_index)) { + // Set up arguments for lease assignment + handle->setArgument("query", query); + handle->setArgument("response", response); + HooksManager::callCallouts(lease_hook_index, *handle); + if (! handle->getSkip()) { + // Skip flag not set, do the address allocation + : + } +} +@endcode + +@section hooksComponentLoadLibraries Loading the User Libraries + +Once hooks are defined, all the hooks code describe above will +work, even if no libraries are loaded (and even if the library +loading method is not called). The CalloutHandle returned by +isc::hooks::HooksManager::createCalloutHandle() will be valid, +isc::hooks::HooksManager::calloutsPresent() will return false for every +index, and isc::hooks::HooksManager::callCallouts() will be a no-op. + +However, if user libraries are specified in the BIND 10 configuration, +the component should load them. (Note the term "libraries": the hooks +framework allows multiple user libraries to be loaded.) This should take +place after the component's configuration has been read, and is achieved +by the isc::hooks::HooksManager::loadLibraries() method. The method is +passed a vector of strings, each giving the full file specification of +a user library: +@code + std::vector libraries = ... // Get array of libraries + bool success = HooksManager::loadLibraries(libraries); +@endcode +loadLibraries() returns a boolean status which is true if all libraries +loaded successfully or false if one or more failed to load. Appropriate +error messages will have been logged in the latter case, the status +being more to allow the developer to decide whether the execution +should proceed in such circumstances. + +If loadLibraries() is called a second or subsequent time (as a result +of a reconfiguration), all existing libraries are unloaded and a new +set loaded. Libraries can be explicitly unloaded either by calling +isc::hooks::HooksManager::unloadLibraries() or by calling +loadLibraries() with an empty vector as an argument. + +@subsection hooksComponentUnloadIssues Unload and Reload Issues + +Unloading a shared library works by unmapping the part of the process's +virtual address space in which the library lies. This may lead to problems +consequences if there are still references to that address space elsewhere +in the process. + +In many operating systems, heap storage allowed by a shared library will +lie in the virtual address allocated to the library. This has implications +in the hooks framework because: + +- Argument information stored in a CalloutHandle by a callout in a library +may lie in the library's address space. +- Data modified in objects passed as arguments may lie in the address +space. For example, it is common for a DHCP callout to add "options" to +a packet: the memory allocated for those options will like in library address +space. + +The problem really arises because of the extensive use by BIND 10 of boost +smart pointers. When the pointer is destroyed, the pointed-to memory is +deallocated. If the pointer points to address space that is unmapped because +a library has been unloaded, the deletion causes a segmentation fault. + +The hooks framework addresses the issue for CalloutHandles by keeping +in that object a shared pointer to the object controlling library +unloading. Although a library can be unloaded at any time, it is only when +all CalloutHandles that could possibly reference address space in the +library have been deleted that the library will be unloaded and the address +space unmapped. + +The hooks framework cannot solve the second issue as the objects in +question are under control of the component. It is up to the component +developer to ensure that all such objects have been destroyed before +libraries are reloaded. In extreme cases this may mean the component +suspending all processing of incoming requests until all currently +executing requests have completed and data object destroyed, reloading +the libraries, then resuming processing. + +@section hooksComponentCallouts Component-Defined Callouts + +Previous sections have discussed callout registration by user libraries. +It is possible for a component to register its own functions (i.e. within +its own address space) as hook callouts. These functions are called +in eactly the same way as user callouts, being passed their arguments +though a CalloutHandle object. (Guidelines for writing callouts can be +found in @ref hooksDevelopersGuide.) + +A component can associate with a hook callouts that run either before +user-registered callouts or after them. Registration is done via a +isc::hooks::LibraryHandle object, a reference to one being obtained +through the methods isc::hooks::HooksManager::preCalloutLibraryHandle() +(for a handle to register callouts to run before the user library +callouts) or isc::hooks::HooksManager::postCalloutLibraryHandle() (for +a handle to register callouts to run after the user callouts). Use of +the LibraryHandle to register and deregister callouts is described in +@ref hooksLibraryHandle. + +Finally, it should be noted that callouts registered in this way only +remain registered until the next call to isc::hooks::loadLibraries(). +It is up to the server to re-register the callouts after this +method has been called. + +*/ -- cgit v1.2.3 From 5e8a8cc152ef5cd151f99389f475b2a16832fb9c Mon Sep 17 00:00:00 2001 From: Marcin Siodelski Date: Tue, 25 Jun 2013 16:30:32 +0200 Subject: [2976] Implemented unit tests for D2UpdateMessage setters. --- src/bin/d2/d2_update_message.cc | 90 +++++++++++++++++++------ src/bin/d2/d2_update_message.h | 40 +++++++---- src/bin/d2/tests/d2_update_message_unittests.cc | 45 +++++++++++-- 3 files changed, 136 insertions(+), 39 deletions(-) diff --git a/src/bin/d2/d2_update_message.cc b/src/bin/d2/d2_update_message.cc index ab8ff16abf..f7fbe25e4e 100644 --- a/src/bin/d2/d2_update_message.cc +++ b/src/bin/d2/d2_update_message.cc @@ -25,8 +25,12 @@ using namespace isc::dns; D2UpdateMessage::D2UpdateMessage(const bool parse) : message_(parse ? dns::Message::PARSE : dns::Message::RENDER) { + // If this object is to create an outgoing message, we have to + // set the proper Opcode field and QR flag here. if (!parse) { message_.setOpcode(Opcode(Opcode::UPDATE_CODE)); + message_.setHeaderFlag(dns::Message::HEADERFLAG_QR, false); + } } @@ -36,20 +40,14 @@ D2UpdateMessage::getQRFlag() const { RESPONSE : REQUEST); } -void -D2UpdateMessage::setQRFlag(const QRFlag flag) { - bool on = (flag == RESPONSE ? true : false); - message_.setHeaderFlag(dns::Message::HEADERFLAG_QR, on); -} - uint16_t -D2UpdateMessage::getQid() const { +D2UpdateMessage::getId() const { return (message_.getQid()); } void -D2UpdateMessage::setQid(const uint16_t qid) { - message_.setQid(qid); +D2UpdateMessage::setId(const uint16_t id) { + message_.setQid(id); } @@ -80,12 +78,16 @@ D2UpdateMessage::endSection(const UpdateMsgSection section) const { void D2UpdateMessage::setZone(const Name& zone, const RRClass& rrclass) { + // The Zone data is kept in the underlying Question class.

It consists of single, abstract operator() which +/// accepts a result code and a pointer to a NameChangeRequest as parameters. +/// In order to receive inbound NCRs, a caller implements a derivation of the +/// RequestReceiveHandler and supplies an instance of this derivation to the +/// NameChangeListener constructor.

This is to provide for error recovery without losing +/// undelivered requests. + +/// It provides virtual methods so derivations may supply implementations to +/// open the appropriate IO sink, perform a send, and close the IO sink. +/// +/// The overall design is based on a callback chain. The sender's caller (the +/// application) supplies an "application" layer callback through which it will +/// be given send completion notifications. The sender derivation will employ +/// its own callback at the IO layer to process send events from its IO sink. +/// This callback is expected to forward the outcome of each asynchronous send +/// to the application layer by invoking the application layer callback +/// registered with the sender. +/// +/// The application layer callback is structured around a nested class, +/// RequestSendHandler. It consists of single, abstract operator() which +/// accepts a result code and a pointer to a NameChangeRequest as parameters. +/// In order to receive send completion notifications, a caller implements a +/// derivation of the RequestSendHandler and supplies an instance of this +/// derivation to the NameChangeSender constructor. This "registers" the +/// handler with the sender. +/// +/// To begin sending, the caller invokes the listener's startSending() +/// method, passing in an IOService instance. This in turn will pass the +/// IOService into the virtual method, open(). The open method is where the +/// sender derivation performs the steps necessary to prepare its IO sink for +/// output (e.g. opening a socket, connecting to a database). At this point, +/// the sender is ready to send messages. +/// +/// In order to send a request, the application layer invokes the sender +/// method, sendRequest(), passing in the NameChangeRequest to send. This +/// method places the request onto the back of the send queue, and then invokes +/// the sender method, sendNext(). +/// +/// If there is already a send in progress when sendNext() is called, the method +/// will return immediately rather than initiate the next send. This is to +/// ensure that sends are processed sequentially. +/// +/// If there is not a send in progress and the send queue is not empty, +/// the sendNext method will pass the NCR at the front of the send queue into +/// the virtual doSend() method. +/// +/// The sender derivation uses this doSend() method to instigate an IO layer +/// asynchronous send with its IO layer callback to handle send events from its +/// IO sink. +/// +/// As stated earlier, the derivation's IO layer callback MUST invoke the +/// application layer handler registered with the sender. This is done by +/// passing in a status indicating the outcome of the send into the sender's +/// invokeSendHandler method.

This construct consists +/// of a set of classes centered around isc::asiolink::UDPSocket. UDPSocket +/// is a templated class that supports asio asynchronous event processing; and +/// which accepts as its parameter, the name of a callback class. +/// +/// The asynchronous services provided by UDPSocket typically accept a buffer +/// for transferring data (either in or out depending on the service direction) +/// and an object which supplies a callback to invoke upon completion of the +/// service. +/// +/// The callback class must provide an operator() with the following signature: +/// @code +/// void operator ()(const asio::error_code error_code, +/// const size_t bytes_transferred); +/// @endcode +/// +/// Upon completion of the service, the callback instance's operator() is +/// invoked by the aiso layer.

However, the nature of the asiolink library +/// is such that the callback object may be copied several times during course +/// of a service invocation. This implies that any class being used as a +/// callback class must be copyable. This is not always desirable. In order +/// to separate the callback class from the NameChangeRequest, the construct +/// defines the UDPCallback class for use as a copyable, callback object. +/// +/// The UDPCallback class provides the asiolink layer callback operator(), +/// which is invoked by the asiolink layer upon service completion.

Information for BIND 10 maintainers can be + found in the @ref hooksComponentDeveloperGuide. + + This manual is more specialised and is aimed at developers of hook + code for the DHCPv4 server. It describes each hook point, what the callouts + attached to the hook are able to do, and the arguments passed to the + callouts. Each entry in this manual has the following information: + + - Name of the hook point. + - Arguments for the callout. As well as the argument name and data type, the + information includes the direction, which can be one of: + - @b in - the server passes values to the callout but ignored any data + returned. + - @b out - the callout is expected to set this value. + - in/out - the server passes a value to the callout and uses whatever + value the callout sends back. Note that the callout may choose not to + do any modification, in which case the server will use whatever value + it sent to the callout. + - Description of the hook. This explains where in the processing the hook + is located, the possible actions a callout attached to this hook could take, + and a description of the data passed to the callouts. + - Skip flag action: the action taken by the server if a callout chooses to set + the "skip" flag. + +@section dhcpv4HooksHookPoints Hooks in the DHCPv4 Server + +The following list is ordered by appearance of specific hook points during +packet processing. Hook points that are not specific to packet processing +(e.g. lease expiration) will be added to the end of this list. + + @subsection dhcpv4HooksPkt4Receive pkt4_receive + + - @b Arguments: + - name: @b query4, type: isc::dhcp::Pkt4Ptr, direction: in/out + + - @b Description: this callout is executed when an incoming DHCPv4 + packet is received and its content is parsed. The sole argument - + query4 - contains a pointer to an isc::dhcp::Pkt4 object that contains + all information regarding incoming packet, including its source and + destination addresses, interface over which it was received, a list + of all options present within and relay information. All fields of + the Pkt4 object can be modified at this time, except data_. (data_ + contains the incoming packet as raw buffer. By the time this hook is + reached, that information has already parsed and is available though + other fields in the Pkt4 object. For this reason, it doesn't make + sense to modify it.) + + - Skip flag action: If any callout sets the skip flag, the server will + drop the packet and start processing the next one. The reason for the drop + will be logged if logging is set to the appropriate debug level. + +@subsection dhcpv4HooksSubnet4Select subnet4_select + + - @b Arguments: + - name: @b query4, type: isc::dhcp::Pkt4Ptr, direction: in/out + - name: @b subnet4, type: isc::dhcp::Subnet4Ptr, direction: in/out + - name: @b subnet4collection, type: const isc::dhcp::Subnet4Collection *, direction: in + + - @b Description: this callout is executed when a subnet is being + selected for the incoming packet. All parameters, addresses and + prefixes will be assigned from that subnet. A callout can select a + different subnet if it wishes so, the list of all subnets currently + configured being provided as 'subnet4collection'. The list itself must + not be modified. + + - Skip flag action: If any callout installed on 'subnet4_select' + sets the skip flag, the server will not select any subnet. Packet processing + will continue, but will be severely limited (i.e. only global options + will be assigned). + +@subsection dhcpv4HooksLeaseSelect lease4_select + + - @b Arguments: + - name: @b subnet4, type: isc::dhcp::Subnet4Ptr, direction: in + - name: @b fake_allocation, type: bool, direction: in + - name: @b lease4, type: isc::dhcp::Lease4Ptr, direction: in/out + + - @b Description: this callout is executed after the server engine + has selected a lease for client's request but before the lease + has been inserted into the database. Any modifications made to the + isc::dhcp::Lease4 object will be stored in the lease's record in the + database. The callout should make sure that any modifications are + sanity checked as the server will use that data as is with no further + checking.\n\n The server processes lease requests for DISCOVER and + REQUEST in a very similar way. The only major difference is that + for DISCOVER the lease is just selected, but not inserted into + the database. It is possible to distinguish between DISCOVER and + REQUEST by checking value of the fake_allocation flag: a value of true + means that the lease won't be inserted into the database (DISCOVER), + a value of false means that it will (REQUEST). + + - Skip flag action: If any callout installed on 'lease4_select' + sets the skip flag, the server will not assign any lease. Packet + processing will continue, but client will not get an address. + +@subsection dhcpv4HooksPkt4Send pkt4_send + + - @b Arguments: + - name: @b response4, type: isc::dhcp::Pkt4Ptr, direction: in/out + + - @b Description: this callout is executed when server's response + is about to be send back to the client. The sole argument - response4 - + contains a pointer to an isc::dhcp::Pkt4 object that contains the + packet, with set source and destination addresses, interface over which + it will be send, list of all options and relay information. All fields + of the Pkt4 object can be modified at this time, except bufferOut_. + (This is scratch space used for constructing the packet after all + pkt4_send callouts are complete, so any changes to that field will + be overwritten.) + + - Skip flag action: if any callout sets the skip flag, the server + will drop this response packet. However, the original request packet + from a client was processed, so server's state was most likely changed + (e.g. lease was allocated).

This in turn will pass the -/// IOService into the virtual method, open(). The open method is where the -/// sender derivation performs the steps necessary to prepare its IO sink for -/// output (e.g. opening a socket, connecting to a database). At this point, -/// the sender is ready to send messages. -/// -/// In order to send a request, the application layer invokes the sender -/// method, sendRequest(), passing in the NameChangeRequest to send. This -/// method places the request onto the back of the send queue, and then invokes -/// the sender method, sendNext(). -/// -/// If there is already a send in progress when sendNext() is called, the method -/// will return immediately rather than initiate the next send. This is to -/// ensure that sends are processed sequentially. -/// -/// If there is not a send in progress and the send queue is not empty, -/// the sendNext method will pass the NCR at the front of the send queue into -/// the virtual doSend() method. -/// -/// The sender derivation uses this doSend() method to instigate an IO layer -/// asynchronous send with its IO layer callback to handle send events from its -/// IO sink. -/// -/// As stated earlier, the derivation's IO layer callback MUST invoke the -/// application layer handler registered with the sender. This is done by -/// passing in a status indicating the outcome of the send into the sender's -/// invokeSendHandler method. This is the mechanism by which the sender's -/// caller is handed outbound notifications. - -/// After invoking the application layer handler, the invokeSendHandler method -/// will call the sendNext() method to initiate the next send. This ensures -/// that requests continue to dequeue and ship. -/// -class NameChangeSender { -public: - - /// @brief Defines the type used for the request send queue. - typedef std::deque SendQueue; - - /// @brief Defines a default maximum number of entries in the send queue. - static const size_t MAX_QUEUE_DEFAULT = 1024; - - /// @brief Defines the outcome of an asynchronous NCR send. - enum Result { - SUCCESS, - TIME_OUT, - STOPPED, - ERROR - }; - - /// @brief Abstract class for defining application layer send callbacks. - /// - /// Applications which will send NameChangeRequests must provide a - /// derivation of this class to the sender constructor in order to - /// receive send outcome notifications. - class RequestSendHandler { - public: - /// @brief Function operator implementing a NCR send callback. - /// - /// This method allows the application to receive the outcome of - /// each send.

This layer is largely unaware of the nature of the -/// data being transmitted. In other words, it doesn't know beans about -/// NCRs. -/// -/// * NameChangeRequest layer - This is the layer which acts as the -/// intermediary between the Application layer and the IO layer. It must -/// be able to move NameChangeRequests to the IO layer as raw data and move -/// raw data from the IO layer in the Application layer as -/// NameChangeRequests. -/// -/// This file defines NameChangeUDPListener class for receiving NCRs, and -/// NameChangeUDPSender for sending NCRs. -/// -/// Both the listener and sender implementations utilize the same underlying -/// construct to move NCRs to and from a UDP socket. This construct consists -/// of a set of classes centered around isc::asiolink::UDPSocket. UDPSocket -/// is a templated class that supports asio asynchronous event processing; and -/// which accepts as its parameter, the name of a callback class. -/// -/// The asynchronous services provided by UDPSocket typically accept a buffer -/// for transferring data (either in or out depending on the service direction) -/// and an object which supplies a callback to invoke upon completion of the -/// service. -/// -/// The callback class must provide an operator() with the following signature: -/// @code -/// void operator ()(const asio::error_code error_code, -/// const size_t bytes_transferred); -/// @endcode -/// -/// Upon completion of the service, the callback instance's operator() is -/// invoked by the asio layer. It is given both a outcome result and the -/// number of bytes either read or written, to or from the buffer supplied -/// to the service. -/// -/// Typically, an asiolink based implementation would simply implement the -/// callback operator directly. However, the nature of the asiolink library -/// is such that the callback object may be copied several times during course -/// of a service invocation. This implies that any class being used as a -/// callback class must be copyable. This is not always desirable. In order -/// to separate the callback class from the NameChangeRequest, the construct -/// defines the UDPCallback class for use as a copyable, callback object. -/// -/// The UDPCallback class provides the asiolink layer callback operator(), -/// which is invoked by the asiolink layer upon service completion. It -/// contains: -/// * a pointer to the transfer buffer -/// * the capacity of the transfer buffer -/// * a IO layer outcome result -/// * the number of bytes transferred -/// * a method pointer to a NameChangeRequest layer completion handler -/// -/// This last item, is critical. It points to an instance method that -/// will be invoked by the UDPCallback operator. This provides access to -/// the outcome of the service call to the NameChangeRequest layer without -/// that layer being used as the actual callback object. -/// -/// The completion handler method signature is codified in the typedef, -/// UDPCompletionHandler, and must be as follows: -/// -/// @code -/// void(const bool, const UDPCallback*) -/// @endcode -/// -/// Note that is accepts two parameters. The first is a boolean indicator -/// which indicates if the service call completed successfully or not. The -/// second is a pointer to the callback object invoked by the IOService upon -/// completion of the service. The callback instance will contain all of the -/// pertinent information about the invocation and outcome of the service. -/// -/// Using the contents of the callback, it is the responsibility of the -/// UDPCompletionHandler to interpret the results of the service invocation and -/// pass the interpretation to the application layer via either -/// NameChangeListener::invokeRecvHandler in the case of the UDP listener, or -/// NameChangeSender::invokeSendHandler in the case of UDP sender. -/// -#include -#include -#include -#include -#include -#include -#include - -#include - -/// responsibility of the completion handler to perform the steps necessary -/// to interpret the raw data provided by the service outcome.

The listener's caller (the +/// application) supplies an "application" layer callback through which it will +/// receive inbound NameChangeRequests. The listener derivation will supply +/// its own callback to the IO layer to process receive events from its IO +/// source.

It consists of single, abstract operator() which +/// accepts a result code and a pointer to a NameChangeRequest as parameters. +/// In order to receive inbound NCRs, a caller implements a derivation of the +/// RequestReceiveHandler and supplies an instance of this derivation to the +/// NameChangeListener constructor. This "registers" the handler with the +/// listener. +/// +/// To begin listening, the caller invokes the listener's startListener() +/// method, passing in an IOService instance. This in turn will pass the +/// IOService into the virtual method, open(). The open method is where the +/// listener derivation performs the steps necessary to prepare its IO source +/// for reception (e.g. opening a socket, connecting to a database). +/// +/// Assuming the open is successful, startListener will call the virtual +/// doReceive() method. The listener derivation uses this method to +/// instigate an IO layer asynchronous passing in its IO layer callback to +/// handle receive events from its IO source. +/// +/// As stated earlier, the derivation's NameChangeRequest completion handler +/// MUST invoke the application layer handler registered with the listener. +/// This is done by passing in either a success status and a populated +/// NameChangeRequest or an error status and an empty request into the +/// listener's invokeRecvHandler method.

Note, it is presumed that +/// a send failure is some form of IO error such as loss of connectivity and +/// not a message content error. It should not be possible to queue an invalid +/// message. +/// +/// It should be noted that once a request is placed onto the send queue it +/// will remain there until one of three things occur: +/// * It is successfully delivered +/// * @c NameChangeSender::skipNext() is called +/// * @c NameChangeSender::clearSendQueue() is called +/// +/// The queue contents are preserved across start and stop listening +/// transitions. This is to provide for error recovery without losing +/// undelivered requests. + +/// It provides virtual methods so derivations may supply implementations to +/// open the appropriate IO sink, perform a send, and close the IO sink. +/// +/// The overall design is based on a callback chain. The sender's caller (the +/// application) supplies an "application" layer callback through which it will +/// be given send completion notifications. The sender derivation will employ +/// its own callback at the IO layer to process send events from its IO sink. +/// This callback is expected to forward the outcome of each asynchronous send +/// to the application layer by invoking the application layer callback +/// registered with the sender. +/// +/// The application layer callback is structured around a nested class, +/// RequestSendHandler. It consists of single, abstract operator() which +/// accepts a result code and a pointer to a NameChangeRequest as parameters. +/// In order to receive send completion notifications, a caller implements a +/// derivation of the RequestSendHandler and supplies an instance of this +/// derivation to the NameChangeSender constructor. This "registers" the +/// handler with the sender. +/// +/// To begin sending, the caller invokes the listener's startSending() +/// method, passing in an IOService instance. This in turn will pass the +/// IOService into the virtual method, open(). The open method is where the +/// sender derivation performs the steps necessary to prepare its IO sink for +/// output (e.g. opening a socket, connecting to a database). At this point, +/// the sender is ready to send messages. +/// +/// In order to send a request, the application layer invokes the sender +/// method, sendRequest(), passing in the NameChangeRequest to send. This +/// method places the request onto the back of the send queue, and then invokes +/// the sender method, sendNext(). +/// +/// If there is already a send in progress when sendNext() is called, the method +/// will return immediately rather than initiate the next send. This is to +/// ensure that sends are processed sequentially. +/// +/// If there is not a send in progress and the send queue is not empty, +/// the sendNext method will pass the NCR at the front of the send queue into +/// the virtual doSend() method. +/// +/// The sender derivation uses this doSend() method to instigate an IO layer +/// asynchronous send with its IO layer callback to handle send events from its +/// IO sink. +/// +/// As stated earlier, the derivation's IO layer callback MUST invoke the +/// application layer handler registered with the sender. This is done by +/// passing in a status indicating the outcome of the send into the sender's +/// invokeSendHandler method. This is the mechanism by which the sender's +/// caller is handed outbound notifications. + +/// After invoking the application layer handler, the invokeSendHandler method +/// will call the sendNext() method to initiate the next send.

This layer is largely unaware of the nature of the +/// data being transmitted. In other words, it doesn't know beans about +/// NCRs. +/// +/// * NameChangeRequest layer - This is the layer which acts as the +/// intermediary between the Application layer and the IO layer. It must +/// be able to move NameChangeRequests to the IO layer as raw data and move +/// raw data from the IO layer in the Application layer as +/// NameChangeRequests. +/// +/// This file defines NameChangeUDPListener class for receiving NCRs, and +/// NameChangeUDPSender for sending NCRs. +/// +/// Both the listener and sender implementations utilize the same underlying +/// construct to move NCRs to and from a UDP socket. This construct consists +/// of a set of classes centered around isc::asiolink::UDPSocket. UDPSocket +/// is a templated class that supports asio asynchronous event processing; and +/// which accepts as its parameter, the name of a callback class. +/// +/// The asynchronous services provided by UDPSocket typically accept a buffer +/// for transferring data (either in or out depending on the service direction) +/// and an object which supplies a callback to invoke upon completion of the +/// service. +/// +/// The callback class must provide an operator() with the following signature: +/// @code +/// void operator ()(const asio::error_code error_code, +/// const size_t bytes_transferred); +/// @endcode +/// +/// Upon completion of the service, the callback instance's operator() is +/// invoked by the asio layer. It is given both a outcome result and the +/// number of bytes either read or written, to or from the buffer supplied +/// to the service. +/// +/// Typically, an asiolink based implementation would simply implement the +/// callback operator directly. However, the nature of the asiolink library +/// is such that the callback object may be copied several times during course +/// of a service invocation. This implies that any class being used as a +/// callback class must be copyable. This is not always desirable. In order +/// to separate the callback class from the NameChangeRequest, the construct +/// defines the UDPCallback class for use as a copyable, callback object. +/// +/// The UDPCallback class provides the asiolink layer callback operator(), +/// which is invoked by the asiolink layer upon service completion. It +/// contains: +/// * a pointer to the transfer buffer +/// * the capacity of the transfer buffer +/// * a IO layer outcome result +/// * the number of bytes transferred +/// * a method pointer to a NameChangeRequest layer completion handler +/// +/// This last item, is critical. It points to an instance method that +/// will be invoked by the UDPCallback operator. This provides access to +/// the outcome of the service call to the NameChangeRequest layer without +/// that layer being used as the actual callback object. +/// +/// The completion handler method signature is codified in the typedef, +/// UDPCompletionHandler, and must be as follows: +/// +/// @code +/// void(const bool, const UDPCallback*) +/// @endcode +/// +/// Note that is accepts two parameters. The first is a boolean indicator +/// which indicates if the service call completed successfully or not. The +/// second is a pointer to the callback object invoked by the IOService upon +/// completion of the service. The callback instance will contain all of the +/// pertinent information about the invocation and outcome of the service. +/// +/// Using the contents of the callback, it is the responsibility of the +/// UDPCompletionHandler to interpret the results of the service invocation and +/// pass the interpretation to the application layer via either +/// NameChangeListener::invokeRecvHandler in the case of the UDP listener, or +/// NameChangeSender::invokeSendHandler in the case of UDP sender. +/// +#include +#include +#include +#include +#include +#include +#include + +#include + +/// responsibility of the completion handler to perform the steps necessary +/// to interpret the raw data provided by the service outcome.

These requests +are implemented in this library by the class, NameChangeRequest. + +This class provides services for constructing the requests as well as +marshalling them to and from various transport formats. Currently, the only +format supported is JSON, however the design of the classes in this library is such that supporting additional formats will be easy to add. + +For sending and receiving NameChangeRequests, this library supplies an abstract +pair of classes, NameChangeSender and NameChangeListener. NameChangeSender +defines the public interface that DHCP_DDNS clients, such as DHCP servers use +for sending requests to DHCP_DDNS. NameChangeListener is used by request +consumers, primarily the DHCP_DDNS service, for receiving the requests. + +By providing abstract interfaces, the implementation isolates the senders and +listeners from any underlying details of request transportation. This was done +to allow support for a variety of transportation mechanisms. Currently, the +only transport supported is via UDP Sockets, though support for TCP/IP sockets +is forthcoming. There may eventually be an implementation which is driven +through an RDBMS. + +The UDP implementation is provided by NameChangeUDPSender and NameChangeUPDListener. +The implementation is strictly unidirectional. This means that there is no explicit +acknowledgement of receipt of a request, and as it is UDP there is no guarantee of +delivery. Once provided, transport via TCP/IP sockets will provide a more reliable +mechanism. + +*/ -- cgit v1.2.3 From a00b45ec9cdb590b973e5c00135f087ebdcb9aa6 Mon Sep 17 00:00:00 2001 From: Thomas Markwalder Date: Fri, 26 Jul 2013 12:08:27 -0400 Subject: [master] Added ChangeLog entry 648 also removed extra brackets from 636, and 637 --- ChangeLog | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index 14b7f954cb..f92b5833d7 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,11 @@ +648.

In +/// addition it may provide a number services to locate entries in the queue +/// such as by FQDN or DHCID. These services may eventually be used +/// for processing optimization.

It is +/// through this operator() that D2QueueMgr is passed inbound NCRs. D2QueueMgr +/// will add each newly received request onto the back of the request queue +/// +/// D2QueueMgr defines a simple state model constructed around the status of +/// its NameChangeListener, consisting of the following states: +/// +/// * NOT_INITTED - D2QueueMgr has been constructed, but its listener has +/// not been initialized. +/// +/// * INITTED - The listener has been initialized, but it is not open for +/// listening. To move from NOT_INITTED to INITTED, one of the D2QueueMgr +/// listener initialization methods must be invoked. Currently there is +/// only one type of listener, NameChangeUDPListener, hence there is only +/// one listener initialization method, initUDPListener. As more listener +/// types are created, listener initialization methods will need to be +/// added. +/// +/// * RUNNING - The listener is open and listening for requests. +/// Once initialized, in order to begin listening for requests, the +/// startListener() method must be invoked. Upon successful completion of +/// of this call, D2QueueMgr will begin receiving requests as they arrive +/// without any further steps. This method may be called from the INITTED +/// or one of the STOPPED states. +/// +/// * STOPPED - The listener has been listening but has been stopped +/// without error. To return to listening, startListener() must be invoked. +/// +/// * STOPPED_QUEUE_FULL - Request queue is full, the listener has been +/// stopped. D2QueueMgr will enter this state when the request queue +/// reaches the maximum queue size. Once this limit is reached, the +/// listener will be closed and no further requests will be received. +/// To return to listening, startListener() must be invoked. Note that so +/// long as the queue is full, any attempt to queue a request will fail. +/// +/// * STOPPED_RECV_ERROR - The listener has experienced a receive error +/// and has been stopped. D2QueueMgr will enter this state when it is +/// passed a failed status into the request completion handler. To return +/// to listening, startListener() must be invoked. +/// +/// D2QueueMgr does not attempt to recover from stopped conditions, this is left +/// to upper layers. +/// +/// It is important to note that the queue contents are preserved between +/// state transitions.

In fact, currently the code has to call Subnet6->getT1() and do not implement any fancy inheritance logic. +@section dhcpv6DDNSIntegration DHCPv6 Server Support for the Dynamic DNS Updates + +The DHCPv6 server supports processing of the DHCPv6 Client FQDN Option described in +the RFC4307. This Option is sent by the DHCPv6 client to instruct the server to +update the DNS mappings for the acquired lease. A client may send its fully +qualified domain name, a partial name or it may choose that server will generate +the name. In the last case, the client sends an empty domain-name field in the +DHCPv6 Client FQDN Option. + +As described in RFC4307, client may choose that the server delegates the forward +DNS update to the client and that the server performs the reverse update only. Current +version of the DHCPv6 server does not support delegation of the forward update +to the client. The implementation of this feature is planned for the future releases. + +The bind10-d2 process is responsible for the actual communication with the DNS +server, i.e. to send DNS Update messages. The bind10-dhcp6 module is responsible +for generating so called @ref isc::d2::NameChangeRequest and sending it to the +bind10-d2 module. The @ref isc::d2::NameChangeRequest object represents changes to the +DNS bindings, related to acquisition, renewal or release of the lease. The bind10-dhcp6 +module implements the simple FIFO queue of the NameChangeRequest objects. The module +logic, which processes the incoming DHCPv6 Client FQDN Options puts these requests +into the FIFO queue. + +@todo Currently the FIFO queue is not processed after the NameChangeRequests are +generated and added to it. In the future implementation steps it is planned to create +a code which will check if there are any outstanding requests in the queue and +send them to the bind10-d2 module when server is idle waiting for DHCP messages. + +Depending on the message type, a DHCPv6 server may generate 0, 1 or 2 NameChangeRequests +during single message processing. Server generates no NameChangeRequests if it is +not configured to update DNS or it rejects the DNS update for any other reason. + +Server may generate 1 NameChangeRequests in a situation when a client acquires a +new lease or it releases an existing lease. In the former case, the NameChangeRequest +type is CHG_ADD, which indicates that the bind10-d2 module should add a new DNS +binding for the client, and it is assumed that there is no DNS binding for this +client already. In the latter case, the NameChangeRequest type is CHG_REMOVE to +indicate to the bind10-d2 module that the existing DNS binding should be removed +from the DNS. The binding consists of the forward and reverse mapping. +A server may only remove the mapping which it had added. Therefore, the lease database +holds an information which updates (no update, reverse only update, both reverse and +forward update) have been performed when the lease was acquired. Server checks +this information to make a decision which mapping it is supposed to remove when +a lease is released. + +Server may generate 2 NameChangeRequests in case the client is renewing a lease and +it already has a DNS binding for that lease. Note, that renewal may be triggered +as a result of sending a RENEW message as well as the REQUEST message. In both cases +DHCPv6 server will check if there is an existing lease for the client which has sent +a message, and if there is it will check in the lease database if the DNS Updates had +been performed for this client. If the notion of client's FQDN changes comparing to +the information stored in the lease database, the DHCPv6 has to remove an existing +binding from the DNS and then add a new binding according to the new FQDN information +received from the client. If the FQDN sent in the message which triggered a renewal +doesn't change (comparing to the information in the lease database) the NameChangeRequest +is not generated. + +@todo The decision about not generating the NameChangeRequest for the client which +renews the lease but doesn't change its FQDN may be wrong in case it is necessary +to inform the bind10-d2 module that the lease has been extended. However, the +house keeper process (which removes DNS bindings for expired leases) will be +implemented within the bind10-dhcp6 module (not the bind10-d2), so there is no +need to store lease lifetime information in the bind10-d2 and thus send it there. + +The DHCPv6 Client FQDN Option is comprises "NOS" flags which communicate to the +server what updates (if any), client expects the server to perform. Server +may be configured to obey client's preference or do FQDN processing in a +different way. If the server overrides client's preference it will communicate it +by sending the DHCPv6 Client FQDN Option in its responses to a client, with +appropriate flags set. + +@todo Note, that current implementation doesn't allow configuration of the server's behaviour +with respect to DNS Updates. This is planned for the future. The default behaviour is +constituted by the set of constants defined in the (upper part of) dhcp6_srv.cc file. +Once the configuration is implemented, these constants will be removed. + @todo Add section about setting up options and their definitions with bindctl. */ -- cgit v1.2.3 From 22cd67d216fb454b2aae9086a7a0afdec3c79c32 Mon Sep 17 00:00:00 2001 From: Yoshitaka Aharen Date: Mon, 5 Aug 2013 11:44:45 +0900 Subject: [2797] expand tabs --- src/bin/auth/b10-auth.xml.pre | 34 +++++++++++++++++----------------- 1 file changed, 17 insertions(+), 17 deletions(-) diff --git a/src/bin/auth/b10-auth.xml.pre b/src/bin/auth/b10-auth.xml.pre index 77d9a7e3b6..b8e29469fd 100644 --- a/src/bin/auth/b10-auth.xml.pre +++ b/src/bin/auth/b10-auth.xml.pre @@ -81,8 +81,8 @@ - Enable verbose logging mode.

Whilst perfectly feasible, there are drawbacks: - -- Although well-documented, BIND 10 is a large program. Just -understanding how it works will take a significant amount of time. In -addition, despite the fact that its object-oriented design keeps the -coupling between modules to a minimum, an inappropriate change to one -part of the program during the extension could cause another to -behave oddly or to stop working altogether. - -- The change may need to be re-applied or re-written with every new -version of BIND 10. As new functionality is added or bugs are fixed, -the code or algorithms in the core software may change - and may change -significantly. - -To overcome these problems, BIND 10 provides the "Hooks" interface - -a defined interface for third-party or user-written code. (For ease of -reference in the rest of this document, all such code will be referred -to as "user code".) At specific points in its processing -("hook points") BIND 10 will make a call to this code. The call passes -data that the user code can examine and, if required, modify. -BIND 10 uses the modified data in the remainder of its processing. - -In order to minimise the interaction between BIND 10 and the user -code, the latter is built independently of BIND 10 in the form of -a shared library (or libraries). These are made known to BIND 10 -through its configuration mechanism, and BIND 10 loads the library at -run time. Libraries can be unloaded and reloaded as needed while BIND -10 is running. - -Use of a defined API and the BIND 10 configuration mechanism means that -as new versions of BIND 10 are released, there is no need to modify -the user code. Unless there is a major change in an interface -(which will be clearly documented), all that will be required is a rebuild -of the libraries. - -@note Although the defined interface should not change, the internals -of some of the classes and structures referenced by the user code may -change between versions of BIND 10. These changes have to be reflected -in the compiled version of the software, hence the need for a rebuild. - -@subsection hooksdgLanguages Languages - -The core of BIND 10 is written in C++. While it is the intention to -provide interfaces into user code written in other languages, the initial -versions of the Hooks system requires that user code be written in C++. -All examples in this guide are in that language. - -@subsection hooksdgTerminology Terminology - -In the remainder of this guide, the following terminology is used: - -- Hook/Hook Point - used interchageably, this is a point in the code at -which a call to user functions is made. Each hook has a name and -each hook can have any number (including 0) of user functions -attached to it. - -- Callout - a user function called by the server at a hook -point. This is so-named because the server "calls out" to the library -to execute a user function. - -- Framework function - the functions that a user library needs to -supply in order for the hooks framework to load and unload the library. - -- User code/user library - non-BIND 10 code that is compiled into a -shared library and loaded by BIND 10 into its address space. - - -@section hooksdgTutorial Tutorial - -To illustrate how to write code that integrates with BIND 10, we will -use the following (rather contrived) example: - -The BIND 10 DHCPv4 server is used to allocate IPv4 addresses to clients -(as well as to pass them other information such as the address of DNS -servers). We will suppose that we need to classify clients requesting -IPv4 addresses according to their hardware address, and want to log both -the hardware address and allocated IP address for the clients of interest. - -The following sections describe how to implement these requirements. -The code presented here is not efficient and there are better ways of -doing the task. The aim however, is to illustrate the main features of -user hook code not to provide an optimal solution. - - -@subsection hooksdgFrameworkFunctions Framework Functions - -Loading and initializing a library holding user code makes use -of three (user-supplied) functions: - -- version - defines the version of BIND 10 code with which the user-library -is built -- load - called when the library is loaded by the server. -- unload - called when the library is unloaded by the server. - -Of these, only "version" is mandatory, although in our example, all three -are used. - -@subsubsection hooksdgVersionFunction The "version" Function - -"version" is used by the hooks framework to check that the libraries -it is loading are compatible with the version of BIND 10 being run. -Although the hooks system allows BIND 10 and user code to interface -through a defined API, the relationship is somewhat tight in that the -user code will depend on the internal structures of BIND 10. If these -change - as they can between BIND 10 releases - and BIND 10 is run with -a version of user code built against an earlier version of BIND -10, a program crash could result. - -To guard against this, the "version" function must be provided in every -library. It returns a constant defined in header files of the version -of BIND 10 against which it was built. The hooks framework checks this -for compatibility with the running version of BIND 10 before loading -the library. - -In this tutorial, we'll put "version" in its own file, version.cc. The -contents are: - -@code -// version.cc - -#include - -extern "C" { - -int version() { - return (BIND10_HOOKS_VERSION); -} - -}; -@endcode - -The file "hooks/hooks.h" is specified relative to the BIND 10 libraries -source directory - this is covered later in the section @ref hooksdgBuild. -It defines the symbol BIND10_HOOKS_VERSION, which has a value that changes -on every release of BIND 10: this is the value that needs to be returned -to the hooks framework. - -A final point to note is that the definition of "version" is enclosed -within 'extern "C"' braces. All functions accessed by the hooks -framework use C linkage, mainly to avoid the name mangling that -accompanies use of the C++ compiler, but also to avoid issues related -to namespaces. - -@subsubsection hooksdgLoadUnloadFunctions The "load" and "unload" Functions - -As the names suggest, "load" is called when a library is loaded and -"unload" called when it is unloaded. (It is always guaranteed that -"load" is called: "unload" may not be called in some circumstances, -e.g. if the system shuts down abnormally.) These functions are the -places where any library-wide resources are allocated and deallocated. -"load" is also the place where any callouts with non-standard names -(names that are not hook point names) can be registered: -this is covered further in the section @ref hooksdgCalloutRegistration. - -The example does not make any use callouts with non-standard names. However, -as our design requires that the log file be open while BIND 10 is active -and the library loaded, we'll open the file in the "load" function and close -it in "unload". - -We create two files, one for the file handle declaration: - -@code -// library_common.h - -#ifndef LIBRARY_COMMON_H -#define LIBRARY_COMMON_H - -#include - -// "Interesting clients" log file handle declaration. -extern std::fstream interesting; - -#endif // LIBRARY_COMMON_H -@endcode - -... and one to hold the "load" and "unload" functions: - -@code -// load_unload.cc - -#include -#include "library_common.h" - -// "Interesting clients" log file handle definition. -std::fstream interesting; - -extern "C" { - -int load(LibraryHandle&) { - interesting.open("/data/clients/interesting.log", - std::fstream::out | std::fstream::app); - return (interesting ? 0 : 1); -} - -int unload() { - if (interesting) { - interesting.close(); - } - return (0); -} - -}; -@endcode - -Notes: -- The file handle ("interesting") is declared in a header file and defined -outside of any function. This means it can be accessed by any function -within the user library. For convenience, the definition is in the -load_unload.cc file. -- "load" is called with a LibraryHandle argument, this being used in -the registration of functions. As no functions are being registered -in this example, the argument specification omits the variable name -(whilst retaining the type) to avoid an "unused variable" compiler -warning. (The LibraryHandle and its use is discussed in the section -@ref hooksdgLibraryHandle.) -- In the current version of the hooks framework, it is not possible to pass -any configuration information to the "load" function. The name of the log -file must therefore be hard-coded as an absolute path name or communicated -to the user code by some other means. -- "load" must 0 on success and non-zero on error. The hooks framework -will abandon the loading of the library if "load" returns an error status. -(In this example, "interesting" can be tested as a boolean value, -returning "true" if the file opened successfully.) -- "unload" closes the log file if it is open and is a no-op otherwise. As -with "load", a zero value must be returned on success and a non-zero value -on an error. The hooks framework will record a non-zero status return -as an error in the current BIND 10 log but otherwise ignore it. -- As before, the function definitions are enclosed in 'extern "C"' braces. - -@subsection hooksdgCallouts Callouts - -Having sorted out the framework, we now come to the functions that -actually do something. These functions are known as "callouts" because -the BIND 10 code "calls out" to them. Each BIND 10 server has a number of -hooks to which callouts can be attached: server-specific documentation -describes in detail the points in the server at which the hooks are -present together with the data passed to callouts attached to them. - -Before we continue with the example, we'll discuss how arguments are -passed to callouts and information is returned to the server. We will -also discuss how information can be moved between callouts. - -@subsubsection hooksdgCalloutSignature The Callout Signature - -All callouts are declared with the signature: -@code -extern "C" { -int callout(CalloutHandle& handle); -}; -@endcode - -(As before, the callout is declared with "C" linkage.) Information is passed -between BIND 10 and the callout through name/value pairs in the CalloutHandle -object. The object is also used to pass information between callouts on a -per-request basis. (Both of these concepts are explained below.) - -A callout returns an "int" as a status return. A value of 0 indicates -success, anything else signifies an error. The status return has no -effect on server processing; the only difference between a success -and error code is that if the latter is returned, the server will -log an error, specifying both the library and hook that generated it. -Effectively the return status provides a quick way for a callout to log -error information to the BIND 10 logging system. - -@subsubsection hooksdgArguments Callout Arguments - -The CalloutHandle object provides two methods to get and set the -arguments passed to the callout. These methods are called (naturally -enough) getArgument and SetArgument. Their usage is illustrated by the -following code snippets. - -@code - // Server-side code snippet to show the setting of arguments - - int count = 10; - boost::shared_ptr pktptr = ... // Set to appropriate value - - // Assume that "handle" has been created - handle.setArgument("data_count", count); - handle.setArgument("inpacket", pktptr); - - // Call the callouts attached to the hook - ... - - // Retrieve the modified values - handle.getArgument("data_count", count); - handle.getArgument("inpacket", pktptr); -@endcode - -In the callout - -@code - int number; - boost::shared_ptr packet; - - // Retrieve data set by the server. - handle.getArgument("data_count", number); - handle.getArgument("inpacket", packet); - - // Modify "number" - number = ...; - - // Update the arguments to send the value back to the server. - handle.setArgument("data_count", number); -@endcode - -As can be seen "getArgument" is used to retrieve data from the -CalloutHandle, and setArgument used to put data into it. If a callout -wishes to alter data and pass it back to the server, it should retrieve -the data with getArgument, modify it, and call setArgument to send -it back. - -There are several points to be aware of: - -- the data type of the variable in the call to getArgument must match -the data type of the variable passed to the corresponding setArgument -exactly: using what would normally be considered to be a -"compatible" type is not enough. For example, if the server passed -an argument as an "int" and the callout attempted to retrieve it as a -"long", an exception would be thrown even though any value that can -be stored in an "int" will fit into a "long". This restriction also -applies the "const" attribute but only as applied to data pointed to by -pointers, e.g. if an argument is defined as a "char*", an exception will -be thrown if an attempt is made to retrieve it into a variable of type -"const char*". (However, if an argument is set as a "const int", it can -be retrieved into an "int".) The documentation of each hook point will -detail the data type of each argument. -- Although all arguments can be modified, some altered values may not -be read by the server. (These would be ones that the server considers -"read-only".) Consult the documentation of each hook to see whether an -argument can be used to transfer data back to the server. -- If a pointer to an object is passed to a callout (either a "raw" -pointer, or a boost smart pointer (as in the example above), and the -underlying object is altered through that pointer, the change will be -reflected in the server even if no call is made to setArgument. - -In all cases, consult the documentation for the particular hook to see whether -parameters can be modified. As a general rule: - -- Do not alter arguments unless you mean the change to be reflected in -the server. -- If you alter an argument, call CalloutHandle::setArgument to update the -value in the CalloutHandle object. - -@subsubsection hooksdgSkipFlag The "Skip" Flag - -When a to callouts attached to a hook returns, the server will usually continue -its processing. However, a callout might have done something that means that -the server should follow another path. Possible actions a server could take -include: - -- Skip the next stage of processing because the callout has already -done it. For example, a hook is located just before the DHCP server -allocates an address to the client. A callout may decide to allocate -special addresses for certain clients, in which case it needs to tell -the server not to allocate an address in this case. -- Drop the packet and continue with the next request. A possible scenario -is a DNS server where a callout inspects the source address of an incoming -packet and compares it against a black list; if the address is on it, -the callout notifies the server to drop the packet. - -To handle these common cases, the CalloutHandle has a "skip" flag. -This is set by a callout when it wishes the server to skip normal -processing. It is set false by the hooks framework before callouts on a -hook are called. If the flag is set on return, the server will take the -"skip" action relevant for the hook. - -The methods to get and set the "skip" flag are getSkip and setSkip. Their -usage is intuitive: - -@code - // Get the current setting of the skip flag. - bool skip = handle.getSkip(); - - // Do some processing... - : - if (lease_allocated) { - // Flag the server to skip the next step of the processing as we - // already have an address. - handle.setSkip(true); - } - return; - -@endcode - -Like arguments, the "skip" flag is passed to all callouts on a hook. Callouts -later in the list are able to examine (and modify) the settings of earlier ones. - -@subsubsection hooksdgCalloutContext Per-Request Context - -Although many of the BIND 10 modules can be characterised as handling -singles packet - e.g. the DHCPv4 server receives a DISCOVER packet, -processes it and responds with an OFFER, this is not true in all cases. -The principal exception is the recursive DNS resolver: this receives a -packet from a client but that packet may itself generate multiple packets -being sent to upstream servers. To avoid possible confusion the rest of -this section uses the term "request" to indicate a request by a client -for some information or action. - -As well as argument information, the CalloutHandle object can be used by -callouts to attach information to a request being handled by the server. -This information (known as "context") is not used by the server: its purpose -is to allow callouts to pass information between one another on a -per-request basis. - -Context only exists only for the duration of the request: when a request -is completed, the context is destroyed. A new request starts with no -context information. Context is particularly useful in servers that may -be processing multiple requests simultaneously: callouts can effectively -attach data to a request that follows the request around the system. - -Context information is held as name/value pairs in the same way -as arguments, being accessed by the pair of methods setContext and -getContext. They have the same restrictions as the setArgument and -getArgument methods - the type of data retrieved from context must -exactly match the type of the data set. - -The example in the next section illustrates their use. - -@subsection hooksdgExampleCallouts Example Callouts - -Continuing with the tutorial, the requirements need us to retrieve the -hardware address of the incoming packet, classify it, and write it, -together with the assigned IP address, to a log file. Although we could -do this in one callout, for this example we'll use two: - -- pkt_rcvd - a callout on this hook is invoked when a packet has been -received and has been parsed. It is passed a single argument, "query" -which is an isc::dhcp::Pkt4 object (representing a DHCP v4 packet). -We will do the classification here. - -- v4_lease_write_post - called when the lease (an assignment of an IPv4 -address to a client for a fixed period of time) has been written to the -database. It is passed two arguments, the query ("query") -and the response (called "reply"). This is the point at which the -example code will write the hardware and IP addresses to the log file. - -The standard for naming callouts is to give them the same name as -the hook. If this is done, the callouts will be automatically found -by the Hooks system (this is discussed further in section @ref -hooksdgCalloutRegistration). For our example, we will assume this is the -case, so the code for the first callout (used to classify the client's -hardware address) is: - -@code -// pkt_rcvd.cc - -#include -#include -#include "library_common.h" - -#include - -using namespace isc::dhcp; -using namespace std; - -extern "C" { - -// This callout is called at the "pkt_rcvd" hook. -int pkt_rcvd(CalloutHandle& handle) { - - // A pointer to the packet is passed to the callout via a "boost" smart - // pointer. The include file "pkt4.h" typedefs a pointer to the Pkt4 - // object as Pkt4Ptr. Retrieve a pointer to the object. - Pkt4Ptr query_ptr; - handle.getArgument("query", query_ptr); - - // Point to the hardware address. - HwAddrPtr hwaddr_ptr = query_ptr->getHWAddr(); - - // The hardware address is held in a public member variable. We'll classify - // it as interesting if the sum of all the bytes in it is divisible by 4. - // (This is a contrived example after all!) - long sum = 0; - for (int i = 0; i < hwaddr_ptr->hwaddr_.size(); ++i) { - sum += hwaddr_ptr->hwadr_[i]; - } - - // Classify it. - if (sum % 4 == 0) { - // Store the text form of the hardware address in the context to pass - // to the next callout. - handle.setContext("hwaddr", hwaddr_ptr->hwaddr_.toText()); - } - - return (0); -}; -@endcode - -The pct_rcvd callout placed the hardware address of an interesting client in -the "hwaddr" context for the packet. Turning now to the callout that will -write this information to the log file: - -@code -// v4_lease_write.cc - -#include -#include -#include "library_common.h" - -#include - -using namespace isc::dhcp; -using namespace std; - -extern "C" { - -// This callout is called at the "v4_lease_write_post" hook. -int v4_lease_write_post(CalloutHandle& handle) { - - // Obtain the hardware address of the "interesting" client. We have to - // use a try...catch block here because if the client was not interesting, - // no information would be set and getArgument would thrown an exception. - string hwaddr; - try (handle.getArgument("hwaddr", hwaddr) { - - // getArgument didn't throw so the client is interesting. Get a pointer - // to the reply. Note that the argument list for this hook also - // contains a pointer to the query: we don't need to access that in this - // example. - Pkt4Ptr reply; - handle.getArgument("reply", reply); - - // Get the string form of the IP address. - string ipaddr = reply->getYiaddr().toText(); - - // Write the information to the log file. - interesting << hwaddr << " " << ipaddr << "\n"; - - // ... and to guard against a crash, we'll flush the output stream. - flush(interesting); - - } catch (const NoSuchCalloutContext&) { - - // No such element in the per-request context with the name - // "hwaddr". We will do nothing, so just dismiss the exception. - - } - - return (0); -} - -}; -@endcode - -@subsection hooksdgBuild Building the Library - -Building the code requires building a shareable library. This requires -the the code be compiled as positition-independent code (using the -compiler's "-fpic" switch) and linked as a shared library (with the -linker's "-shared" switch). The build command also needs to point to -the BIND 10 include directory and link in the appropriate libraries. - -Assuming that BIND 10 has been installed in the default location, the -command line needed to create the library using the Gnu C++ compiler on a -Linux system is: - -@code -g++ -I /usr/include/bind10 -L /usr/lib/bind10 -fpic -shared -o example.so \ - load_unload.cc pkt_rcvd.cc v4_lease_write.cc version.cc \ - -lb10-dhcp++ -lb10-util -lb10-exceptions -@endcode - -Notes: -- The compilation command and switches required may vary depending on -your operating system and compiler - consult the relevant documentation -for details. -- The values for the "-I" and "-L" switches depend on where you have -installed BIND 10. -- The list of libraries that need to be included in the command line -depends on the functionality used by the hook code and the module to -which they are attached (e.g. hook code for DNS will need to link against -the libb10-dns++ library). Depending on operating system, you may also need -to explicitly list libraries on which the BIND 10 libraries depend. - -@subsection hooksdgConfiguration Configuring the Hook Library - -The final step is to make the library known to BIND 10. All BIND 10 modules to -which hooks can be added contain the "hook_library" element, and user -libraries are added to this. (The BIND 10 hooks system can handle multiple libraries - this is discussed below.). - -To add the example library (assumed to be in /usr/local/lib) to the DHCPv4 -module, the following bindctl commands must be executed: - -@code -> config add Dhcp4/hook_libraries -> config set Dhcp4/hook_libraries[0] "/usr/local/lib/example.so" -> config commit -@endcode - -The DHCPv4 server will load the library and execute the callouts each time a -request is received. - -@section hooksdgAdvancedTopics Advanced Topics - -@subsection hooksdgContextCreateDestroy Context Creation and Destruction - -As well as the hooks defined by the server, the hooks framework defines -two hooks of its own, "context_create" and "context_destroy". The first -is called when a request is created in the server, before any of the -server-specific hooks gets called. It's purpose it to allow a library -to initialize per-request context. The second is called after all -server-defined hooks have been processed, and is to allow a library to -tidy up. - -As an example, the v4_lease_write example above required that the code -check for an exception being thrown when accessing the "hwaddr" context -item in case it was not set. An alternative strategy would have been to -provide a callout for the "context_create" hook and set the context item -"hwaddr" to an empty string. Instead of needing to handle an exception, -v4_lease_write would be guaranteed to get something when looking for -the hwaddr item and so could write or not write the output depending on -the value. - -In most cases, "context_destroy" is not needed as the Hooks system -automatically deletes context. An example where it could be required -is where memory has been allocated by a callout during the processing -of a request and a raw pointer to it stored in the context object. On -destruction of the context, that memory will not be automatically -released. Freeing in the memory in the "context_destroy callout will solve -that problem. - -Actually, when the context is destroyed, the destructor -associated with any objects stored in it are run. Rather than point to -allocated memory with a raw pointer, a better idea would be to point to -it with a boost "smart" pointer and store that pointer in the context. -When the context is destroyed, the smart pointer's destructor is run, -which will automatically delete the pointed-to object. - -These approaches are illustrated in the following examples. -Here it is assumed that the hooks library is performing some form of -security checking on the packet and needs to maintain information in -a user-specified "SecurityInformation" object. (The details of this -fictitious object are of no concern here.) The object is created in -the context_create callout and used in both the pkt4_rcvd and the -v4_lease_write_post callouts. - -@code -// Storing information in a "raw" pointer. Assume that the - -#include - : - -extern "C" { - -// context_create callout - called when the request is created. -int context_create(CalloutHandle& handle) { - // Create the security information and store it in the context - // for this packet. - SecurityInformation* si = new SecurityInformation(); - handle.setContext("security_information", si); -} - -// Callouts that use the context -int pktv_rcvd(CalloutHandle& handle) { - // Retrieve the pointer to the SecurityInformation object - SecurityInformation si; - handle.getContext("security_information", si); - : - : - // Set the security information - si->setSomething(...); - - // The pointed-to information has been updated but the pointer has not been - // altered, so there is no need to call setContext() again. -} - -int v4_lease_write_post(CalloutHandle& handle) { - // Retrieve the pointer to the SecurityInformation object - SecurityInformation si; - handle.getContext("security_information", si); - : - : - // Retrieve security information - bool active = si->getSomething(...); - : -} - -// Context destruction. We need to delete the pointed-to SecurityInformation -// object because we will lose the pointer to it when the CalloutHandle is -// destroyed. -int context_destroy(CalloutHandle& handle) { - // Retrieve the pointer to the SecurityInformation object - SecurityInformation si; - handle.getContext("security_information", si); - - // Delete the pointed-to memory. - delete si; -} -@endcode - -The requirement for the context_destroy callout can be eliminated if -a Boost shared ptr is used to point to the allocated memory: - -@code -// Storing information in a "raw" pointer. Assume that the - -#include -#include - : - -extern "C" { - -// context_create callout - called when the request is created. - -int context_create(CalloutHandle& handle) { - // Create the security information and store it in the context for this - // packet. - boost::shared_ptr si(new SecurityInformation()); - handle.setContext("security_information", si); -} - -// Other than the data type, a shared pointer has similar semantics to a "raw" -// pointer. Only the code from pkt_rcvd is shown here. - -int pktv_rcvd(CalloutHandle& handle) { - // Retrieve the pointer to the SecurityInformation object - boost::shared_ptr si; - handle.setContext("security_information", si); - : - : - // Modify the security information - si->setSomething(...); - - // The pointed-to information has been updated but the pointer has not - // altered, so theree is no need to reset the context. -} - -// No context_destroy callout is needed to delete the allocated -// SecurityInformation object. When the CalloutHandle is destroyed, the shared -// pointer object will be destroyed. If that is the last shared pointer to the -// allocated memory, then it too will be deleted. -@endcode - -(Note that a Boost shared pointer - rather than any other Boost smart pointer - -should be used, as the pointer objects are copied within the hooks framework and -only shared pointers have the correct behavior for the copy operation.) - - -@subsection hooksdgCalloutRegistration Registering Callouts - -As briefly mentioned in @ref hooksdgExampleCallouts, the standard is for -callouts in the user library to have the same name as the name of the -hook to which they are being attached. This convention was followed -in the tutorial, e.g. the callout that needed to be attached to the -"pkt_rcvd" hook was named pkt_rcvd. - -The reason for this convention is that when the library is loaded, the -hook framework automatically searches the library for functions with -the same names as the server hooks. When it finds one, it attaches it -to the appropriate hook point. This simplifies the loading process and -bookkeeping required to create a library of callouts. - -However, the hooks system is flexible in this area: callouts can have -non-standard names, and multiple callouts can be registered on a hook. - -@subsubsection hooksdgLibraryHandle The LibraryHandle Object - -The way into the part of the hooks framework that allows callout -registration is through the LibraryHandle object. This was briefly -introduced in the discussion of the framework functions, in that -an object of this type is pass to the "load" function. A LibraryHandle -can also be obtained from within a callout by calling the CalloutHandle's -getLibraryHandle() method. - -The LibraryHandle provides three methods to manipulate callouts: - -- registerCallout - register a callout on a hook. -- deregisterCallout - deregister a callout from a hook. -- deregisterAllCallouts - deregister all callouts on a hook. - -The following sections cover some of the ways in which these can be used. - -@subsubsection hooksdgNonstandardCalloutNames Non-Standard Callout Names - -The example in the tutorial used standard names for the callouts. As noted -above, it is possible to use non-standard names. Suppose, instead of the -callout names "pkt_rcvd" and "v4_lease_write", we had named our callouts -"classify" and "write_data". The hooks framework would not have registered -these callouts, so we would have needed to do it ourself. The place to -do this is the "load" framework function, and its code would have had to -been modified to: - -@code -int load(LibraryHandle& libhandle) { - // Register the callouts on the hooks. We assume that a header file - // declares the "classify" and "write_data" functions. - libhandle.registerCallout("pkt_rcvd", classify); - libhandle.registerCallout("v4_lease_write", write_data); - - // Open the log file - interesting.open("/data/clients/interesting.log", - std::fstream::out | std::fstream::app); - return (interesting ? 0 : 1); -} -@endcode - -It is possible for a library to contain callouts with both standard and -non-standard names: ones with standard names will be registered automatically, -ones with non-standard names need to be registered manually. - -@subsubsection hooksdgMultipleCallouts Multiple Callouts on a Hook - -The BIND 10 hooks framework allows multiple callouts to be attached to -a hook point. Although it is likely to be rare for user code to need to -do this, there may be instances where it make sense. - -To register multiple callouts on a hook, just call -LibraryHandle::registerCallout multiple times on the same hook, e.g. - -@code - libhandle.registerCallout("pkt_rcvd", classify); - libhandle.registerCallout("pkt_rcvd", write_data); -@endcode - -The hooks framework will call the callouts in the order they are -registered. The same CalloutHandle is passed between them, so any -change made to the CalloutHandle's arguments, "skip" flag, or per-request -context by the first is visible to the second. - -@subsubsection hooksdgDynamicRegistration Dynamic Registration and Reregistration of Callouts - -The previous sections have dealt with callouts being registered during -the call to "load". The hooks framework is more flexible than that -in that callouts can be registered and deregistered within a callout. -In fact, a callout is able to register or deregister itself, and a callout -is able to be registered on a hook multiple times. - -Using our contrived example again, the DHCPv4 server processes one request -to completion before it starts processing the next. With this knowledge, -we could alter the logic of the code so that the callout attached to the -"pkt_rcvd" hook registers the callout doing the logging when it detects -an interesting packet, and the callout doing the logging deregisters -itself in its execution. The relevant modifications to the code in -the tutorial are shown below: - -@code -// pkt_rcvd.cc -// : - -int pkt_rcvd(CalloutHandle& handle) { - - : - : - - // Classify it. - if (sum % 4 == 0) { - // Store the text form of the hardware address in the context to pass - // to the next callout. - handle.setContext("hwaddr", hwaddr_ptr->hwaddr_.toText()); - - // Register the callback to log the data. - handle.getLibraryHandle().registerCallout("v4_lease_write", write_data); - } - - return (0); -}; -@endcode - -@code -// v4_lease_write.cc - : - -int write_data(CalloutHandle& handle) { - - // Obtain the hardware address of the "interesting" client. As the - // callback is only registered when interesting data is present, we - // know that the context contains the hardware address so an exception - // will not be thrown when we call getArgument(). - string hwaddr; - handle.getArgument("hwaddr", hwaddr); - - // The pointer to the reply. - ConstPkt4Ptr reply; - handle.getArgument("reply", reply); - - // Get the string form of the IP address. - string ipaddr = reply->getYiaddr().toText(): - - // Write the information to the log file and flush. - interesting << hwaddr << " " << ipaddr << "\n"; - flush(interesting); - - // We've logged the data, so deregister ourself. This callout will not - // be called again until it is registered by pkt_rcvd. - - handle.getLibraryHandle().deregisterCallout("v4_lease_write", write_data); - - return (0); -} -@endcode - -Note that the above example used a non-standard name for the callout -that wrote the data. Had the name been a standard one, it would have been -registered when the library was loaded and called for the first request, -regardless of whether that was defined as "interesting". (Although as -callouts with standard names are always registered before "load" gets called, -we could have got round that problem by deregistering that particular -callout in the "load" function.) - - -@note Deregistration of a callout on the hook that is currently -being called only takes effect when the server next calls the hook. -To illustrate this, suppose the callouts attached to a hook are A, B and C -(in that order), and during execution, A deregisters B and C and adds D. -When callout A returns, B and C will still run. The next time the server -calls the hook's callouts, A and D will run (in that order). - -@subsection hooksdgMultipleLibraries Multiple User Libraries - -As alluded to in the section @ref hooksdgConfiguration, BIND 10 can load -multiple libraries. The libraries are loaded in the order specified in -the configuration, and the callouts attached to the hooks in the order -presented by the libraries. - -The following picture illustrates this, and also illustrates the scope of -data passed around the system. - -@image html DataScopeArgument.png "Scope of Arguments" - -In this illustration, a server has three hook points, alpha, beta -and gamma. Two libraries are configured, library 1 and library 2. -Library 1 registers the callout "authorize" for hook alpha, "check" for -hook beta and "add_option" for hook gamma. Library 2 registers "logpkt", -"validate" and "putopt" - -The horizontal red lines represent arguments to callouts. When the server -calls hook alpha, it creates an argument list and calls the -first callout for the hook, "authorize". When that callout returns, the -same (but possibly modified) argument list is passed to the next callout -in the chain, "logpkt". Another, separate argument list is created for -hook beta and passed to the callouts "check" and "validate" in -that order. A similar sequence occurs for hook gamma. - -The next picture shows the scope of the context associated with a -request. - -@image html DataScopeContext.png "Illustration of per-library context" - -The vertical blue lines represent callout context. Context is -per-packet but also per-library. When the server calls "authorize", -the CalloutHandle's getContext and setContext methods access a context -created purely for library 1.

It provides an overview of the classes that make up the hooks + framework and notes important aspects of processing. More detailed + information can be found in the source code. + + It is assumed that the reader is familiar with the contents of the @ref + hooksdgDevelopersGuide and the @ref hooksComponentDeveloperGuide. + + @section hooksmgObjects Hooks Framework Objects + + The relationships betweeh the various objects in the hooks framework + is shown below: + + @image html HooksUml.png "High-Level Class Diagram of the Hooks Framework" + + (To avoid clutter, the @ref hooksmgServerHooks object, used to pass + information about registered hooks to the components, is not shown on + the diagram.) + + The hooks framework objects can be split into user-side objects and + server-side objects. The former are those objects used or referenced + by user-written hooks libraries. The latter are those objects used in + the hooks framework. + + @subsection hooksmgUserObjects User-Side Objects + + The user-side code is able to access two objects in the framework, + the @ref hooksmgCalloutHandle and the @ref hooksmgLibraryHandle. + The @ref hooksmgCalloutHandle is used to pass data between the BIND 10 + component and the loaded library; the @ref hooksmgLibraryHandle is used + for registering callouts. + + @subsubsection hooksmgCalloutHandle Callout Handle + + The @ref isc::hooks::CalloutHandle has two functions: passing arguments + between the BIND 10 component and the user-written library, and storing + per-request context between library calls. In both cases the data is + stored in a std::map structure, keyed by argument (or context item) name. + The actual data is stored in a boost::any object, which allows any + data type to be stored, although a penalty for this flexibility is + the restriction (mentioned in the @ref hooksdgDevelopersGuide) that + the type of data retrieved must be identical (and not just compatible) + with that stored. + + The storage of context data is slightly complex because there is + separate context for each user library. For this reason, the @ref + hooksmgCalloutHandle has multiple maps, one for each library loaded. + The maps are stored in another map, the appropriate map being identified + by the "current library index" (this index is explained further below). + The reason for the second map (rather than a structure such as a vector) + is to avoid creating individual context maps unless needed; given the + key to the map (in this case the current library index) accessing an + element in a map using the operator[] method returns the element in + question if it exists, or creates a new one (and stores it in the map) + if its doesn't. + + @subsubsection hooksmgLibraryHandle Library Handle + + Little more than a restricted interface to the @ref + hooksmgCalloutManager, the @ref isc::hooks::LibraryHandle allows a + callout to register and deregister callouts. However, there are some + quirks to callout registration which, although the processing involved + is in the @ref hooksmgCalloutManager, are best described here. + + Firstly, a callout can be deregistered by a function within a user + library only if it was registered by a function within that library. That + is to say, if library A registers the callout A_func() on hook "alpha" + and library B registers B_func(), functions within library A are only + able to remove A_func() (and functions in library B remove B_func()). + The restriction - here to prevent one library interfering with the + callouts of another - is enforced by means of the current library index. + As described below, each entry in the vector of callouts associated with + a hook is a pair object, comprising a pointer to the callout and + the index of the library with which it is associated. A callout + can only modify entries in that vector where the current library index + matches the index element of the pair. + + A second quirk is that when dynamically modifying the list of callouts, + the change only takes effect when the current call out from the server + completes. To clarify this, suppose that functions A_func(), B_func() + and C_func() are registered on a hook, and the server executes a callout + on the hook. Suppose also during this call, A_func() removes the callout + C_func() and that B_func() adds D_func(). As changes only take effect + when the current call out completes, the user callouts executed will be + A_func(), B_func() then C_func(). When the server calls the hook callouts + again, the functions executed will be A_func(), B_func() and D_func(). + + This restriction is down to implementation. When a set of callouts on a hook + is being called, the @ref hooksmgCalloutManager iterates through a + vector (the "callout vector") of (index, callout pointer) pairs. Since + registration or deregistration of a callout on that hook would change the + vector (and so potentially invalidate the iterators used to access the it), + a copy of the vector is taken before the iteration starts. The @ref + hooksmgCalloutManager iterates over this copy while any changes made + by the callout registration functions affect the relevant callout vector. + + @subsection hooksmgServerObjects Server-Side Objects + + @subsubsection hooksmgServerHooks Server Hooks + + The singleton @ref isc::hooks::ServerHooks object is used to register + hooks. It is little more than a wrapper around a map of (hook index, + hook name), generating a unique number (the hook index) for each + hook registered. It also handles the registration of the pre-defined + context_create and context_destroy hooks. + + In operation, the @ref hooksmgHooksManager provides a thin wrapper + around it, so that the BIND 10 component developer does not have to + worry about another object. + + @subsubsection hooksmgLibraryManager Library Manager + + An @ref isc::hooks::LibraryManager is created by the @ref + hooksmgHooksManager object for each shared library loaded. It + controls the loading and unloading of the library and in essence + represents the library in the hooks framework. It also handles the + registration of the standard callouts (functions in the library with + the same name as the hook name). + + Of particular importance is the "library's index", a number associated + with the library. This is passed to the LibraryManager at creation + time and is used to tag the callout pointers. It is discussed + further below. + + As the LibraryManager provides all the methods needed to manage the + shared library, it is the natural home for the static validateLibrary() + method. The function called the parsing of the BIND 10 configuration, when + the "hooks-libraries" element is processed. It checks that shared library + exists, that it can be opened, that it contains the "version()" function + and that that function returns a valid value. It then closes the shared + library and returns an appropriate indication as to the library status. + + @subsubsection hooksmgLibraryManagerCollection Library Manager Collection + + The hooks framework can handle multiple libraries and as + a result will create a @ref hooksmgLibraryManager for each + of them. The collection of LibraryManagers is managed by the + @ref isc::hooks::LibraryManagerCollection object which, in most + cases has a method corresponding to a @ref hooksmgLibraryManager + method, e.g. it has a loadLibraries() that corresponds to the @ref + hooksmgLibraryManager's loadLibrary() call. As would be expected, methods + on the LibraryManagerCollection iterate through all specified libraries, + calling the corresponding LibraryManager method for each library. + + One point of note is that LibraryManagerCollection operates on an "all + or none" principle. When loadLibraries() is called, on exit either all + libraries have been successfully opened or none of them have. There + is no use-case in BIND 10 where, after a user has specified the shared + libraries they want to load, the system will operate with only some of + them loaded. + + The LibraryManagerCollection is the place where each library's index is set. + Each library is assigned a number ranging from 1 through to the number + of libraries being loaded. As mentioned in the previous section, this + index is used to tag callout pointers, something that is discussed + in the next section. + + (Whilst on the subject of library index numbers, two additional + numbers - 0 and INT_MAX - are also valid as "current library index". + For flexibility, the BIND 10 component is able to register its own + functions as hook callouts. It does this by obtaining a suitable @ref + hooksmgLibraryHandle from the @ref hooksmgHooksManager. A choice + of two is available: one @ref hooksmgLibraryHandle (with an index + of 0) can be used to register a callout on a hook to execute before + any user-supplied callouts. The second (with an index of INT_MAX) + is used to register a callout to run after user-specified callouts. + Apart from the index number, the hooks framework does not treat these + callouts any differently from user-supplied ones.) + + @subsubsection hooksmgCalloutManager Callout Manager + + The @ref isc::hooks::CalloutManager is the core of the framework insofar + as the registration and calling of callouts is concerned. + + It maintains a "hook vector - a vector with one element for + each registered hook. Each element in this vector is itself a + vector (the callout vector), each element of which is a pair of + (library index, callback pointer). When a callout is registered, the + CalloutManager's current library index is used to supply the "library + index" part of the pair. The library index is set explicitly by the + @ref hooksmgLibraryManager prior to calling the user library's load() + function (and prior to registering the standard callbacks). + + The situation is slightly more complex when a callout is executing. In + order to execute a callout, the CalloutManager's callCallouts() + method must be called. This iterates through the callout vector for + a hook and for each element in the vector, uses the "library index" + part of the pair to set the "current library index" before calling the + callout function recorded in the second part of the pair. In most cases, + the setting of the library index has no effect on the callout. However, + if the callout wishes to dynamically register or deregister a callout, + the @ref hooksmgLibraryHandle (see above) calls a method on the + @ref hooksmgCalloutManager which in turn uses that information. + + @subsubsection hooksmgHooksManager Hooks Manager + + The @ref isc::hooks::HooksManager is the main object insofar as the + server is concerned. It controls the creation of the library-related + objects and provides the framework in which they interact. It also + provides a shell around objects such as @ref hooksmgServerHooks so that all + interaction with the hooks framework by the server is through the + HooksManager object. Apart from this, it supplies no functionality to + the hooks framework. + + @section hooksmgOtherIssues Other Issues + + @subsection hooksmgMemoryAllocation Memory Allocation + + Unloading a shared library works by unmapping the part of the process's + virtual address space in which the library lies. This may lead to + problems if there are still references to that address space elsewhere + in the process. + + In many operating systems, heap storage allowed by a shared library + will lie in the virtual address allocated to the library. This has + implications in the hooks framework because: + + - Argument information stored in a @ref hooksmgCalloutHandle by a + callout in a library may lie in the library's address space. + + - Data modified in objects passed as arguments may lie in the address + space. For example, it is common for a DHCP callout to add "options" + to a packet: the memory allocated for those options will most likely + lie in library address space. + + The problem really arises because of the extensive use by BIND 10 of + boost smart pointers. When the pointer is destroyed, the pointed-to + memory is deallocated. If the pointer points to address space that is + unmapped because a library has been unloaded, the deletion causes a + segmentation fault. + + The hooks framework addresses the issue for the @ref hooksmgCalloutHandle + by keeping in that object a shared pointer to the object controlling + library unloading (the @ref hooksmgLibraryManagerCollection). Although + the libraries can be unloaded at any time, it is only when every + @ref hooksmgCalloutHandle that could possibly reference address space in the + library have been deleted that the library will actually be unloaded + and the address space unmapped. + + The hooks framework cannot solve the second issue as the objects in + question are under control of the BIND 10 server incorporating the + hooks. It is up to the server developer to ensure that all such objects + have been destroyed before libraries are reloaded. In extreme cases + this may mean the server suspending all processing of incoming requests + until all currently executing requests have completed and data object + destroyed, reloading the libraries, then resuming processing. +*/ diff --git a/src/lib/hooks/hooks_user.dox b/src/lib/hooks/hooks_user.dox new file mode 100644 index 0000000000..8aa75c118b --- /dev/null +++ b/src/lib/hooks/hooks_user.dox @@ -0,0 +1,1031 @@ +// Copyright (C) 2013 Internet Systems Consortium, Inc.

Whilst perfectly feasible, there are drawbacks: + +- Although well-documented, BIND 10 is a large program. Just +understanding how it works will take a significant amount of time. In +addition, despite the fact that its object-oriented design keeps the +coupling between modules to a minimum, an inappropriate change to one +part of the program during the extension could cause another to +behave oddly or to stop working altogether. + +- The change may need to be re-applied or re-written with every new +version of BIND 10. As new functionality is added or bugs are fixed, +the code or algorithms in the core software may change - and may change +significantly. + +To overcome these problems, BIND 10 provides the "Hooks" interface - +a defined interface for third-party or user-written code. (For ease of +reference in the rest of this document, all such code will be referred +to as "user code".) At specific points in its processing +("hook points") BIND 10 will make a call to this code. The call passes +data that the user code can examine and, if required, modify. +BIND 10 uses the modified data in the remainder of its processing. + +In order to minimise the interaction between BIND 10 and the user +code, the latter is built independently of BIND 10 in the form of +a shared library (or libraries). These are made known to BIND 10 +through its configuration mechanism, and BIND 10 loads the library at +run time. Libraries can be unloaded and reloaded as needed while BIND +10 is running. + +Use of a defined API and the BIND 10 configuration mechanism means that +as new versions of BIND 10 are released, there is no need to modify +the user code. Unless there is a major change in an interface +(which will be clearly documented), all that will be required is a rebuild +of the libraries. + +@note Although the defined interface should not change, the internals +of some of the classes and structures referenced by the user code may +change between versions of BIND 10. These changes have to be reflected +in the compiled version of the software, hence the need for a rebuild. + +@subsection hooksdgLanguages Languages + +The core of BIND 10 is written in C++. While it is the intention to +provide interfaces into user code written in other languages, the initial +versions of the Hooks system requires that user code be written in C++. +All examples in this guide are in that language. + +@subsection hooksdgTerminology Terminology + +In the remainder of this guide, the following terminology is used: + +- Hook/Hook Point - used interchageably, this is a point in the code at +which a call to user functions is made. Each hook has a name and +each hook can have any number (including 0) of user functions +attached to it. + +- Callout - a user function called by the server at a hook +point. This is so-named because the server "calls out" to the library +to execute a user function. + +- Framework function - the functions that a user library needs to +supply in order for the hooks framework to load and unload the library. + +- User code/user library - non-BIND 10 code that is compiled into a +shared library and loaded by BIND 10 into its address space. + + +@section hooksdgTutorial Tutorial + +To illustrate how to write code that integrates with BIND 10, we will +use the following (rather contrived) example: + +The BIND 10 DHCPv4 server is used to allocate IPv4 addresses to clients +(as well as to pass them other information such as the address of DNS +servers). We will suppose that we need to classify clients requesting +IPv4 addresses according to their hardware address, and want to log both +the hardware address and allocated IP address for the clients of interest. + +The following sections describe how to implement these requirements. +The code presented here is not efficient and there are better ways of +doing the task. The aim however, is to illustrate the main features of +user hook code not to provide an optimal solution. + + +@subsection hooksdgFrameworkFunctions Framework Functions + +Loading and initializing a library holding user code makes use +of three (user-supplied) functions: + +- version - defines the version of BIND 10 code with which the user-library +is built +- load - called when the library is loaded by the server. +- unload - called when the library is unloaded by the server. + +Of these, only "version" is mandatory, although in our example, all three +are used. + +@subsubsection hooksdgVersionFunction The "version" Function + +"version" is used by the hooks framework to check that the libraries +it is loading are compatible with the version of BIND 10 being run. +Although the hooks system allows BIND 10 and user code to interface +through a defined API, the relationship is somewhat tight in that the +user code will depend on the internal structures of BIND 10. If these +change - as they can between BIND 10 releases - and BIND 10 is run with +a version of user code built against an earlier version of BIND +10, a program crash could result. + +To guard against this, the "version" function must be provided in every +library. It returns a constant defined in header files of the version +of BIND 10 against which it was built. The hooks framework checks this +for compatibility with the running version of BIND 10 before loading +the library. + +In this tutorial, we'll put "version" in its own file, version.cc. The +contents are: + +@code +// version.cc + +#include + +extern "C" { + +int version() { + return (BIND10_HOOKS_VERSION); +} + +}; +@endcode + +The file "hooks/hooks.h" is specified relative to the BIND 10 libraries +source directory - this is covered later in the section @ref hooksdgBuild. +It defines the symbol BIND10_HOOKS_VERSION, which has a value that changes +on every release of BIND 10: this is the value that needs to be returned +to the hooks framework. + +A final point to note is that the definition of "version" is enclosed +within 'extern "C"' braces. All functions accessed by the hooks +framework use C linkage, mainly to avoid the name mangling that +accompanies use of the C++ compiler, but also to avoid issues related +to namespaces. + +@subsubsection hooksdgLoadUnloadFunctions The "load" and "unload" Functions + +As the names suggest, "load" is called when a library is loaded and +"unload" called when it is unloaded. (It is always guaranteed that +"load" is called: "unload" may not be called in some circumstances, +e.g. if the system shuts down abnormally.) These functions are the +places where any library-wide resources are allocated and deallocated. +"load" is also the place where any callouts with non-standard names +(names that are not hook point names) can be registered: +this is covered further in the section @ref hooksdgCalloutRegistration. + +The example does not make any use callouts with non-standard names. However, +as our design requires that the log file be open while BIND 10 is active +and the library loaded, we'll open the file in the "load" function and close +it in "unload". + +We create two files, one for the file handle declaration: + +@code +// library_common.h + +#ifndef LIBRARY_COMMON_H +#define LIBRARY_COMMON_H + +#include + +// "Interesting clients" log file handle declaration. +extern std::fstream interesting; + +#endif // LIBRARY_COMMON_H +@endcode + +... and one to hold the "load" and "unload" functions: + +@code +// load_unload.cc + +#include +#include "library_common.h" + +// "Interesting clients" log file handle definition. +std::fstream interesting; + +extern "C" { + +int load(LibraryHandle&) { + interesting.open("/data/clients/interesting.log", + std::fstream::out | std::fstream::app); + return (interesting ? 0 : 1); +} + +int unload() { + if (interesting) { + interesting.close(); + } + return (0); +} + +}; +@endcode + +Notes: +- The file handle ("interesting") is declared in a header file and defined +outside of any function. This means it can be accessed by any function +within the user library. For convenience, the definition is in the +load_unload.cc file. +- "load" is called with a LibraryHandle argument, this being used in +the registration of functions. As no functions are being registered +in this example, the argument specification omits the variable name +(whilst retaining the type) to avoid an "unused variable" compiler +warning. (The LibraryHandle and its use is discussed in the section +@ref hooksdgLibraryHandle.) +- In the current version of the hooks framework, it is not possible to pass +any configuration information to the "load" function. The name of the log +file must therefore be hard-coded as an absolute path name or communicated +to the user code by some other means. +- "load" must 0 on success and non-zero on error. The hooks framework +will abandon the loading of the library if "load" returns an error status. +(In this example, "interesting" can be tested as a boolean value, +returning "true" if the file opened successfully.) +- "unload" closes the log file if it is open and is a no-op otherwise. As +with "load", a zero value must be returned on success and a non-zero value +on an error. The hooks framework will record a non-zero status return +as an error in the current BIND 10 log but otherwise ignore it. +- As before, the function definitions are enclosed in 'extern "C"' braces. + +@subsection hooksdgCallouts Callouts + +Having sorted out the framework, we now come to the functions that +actually do something. These functions are known as "callouts" because +the BIND 10 code "calls out" to them. Each BIND 10 server has a number of +hooks to which callouts can be attached: server-specific documentation +describes in detail the points in the server at which the hooks are +present together with the data passed to callouts attached to them. + +Before we continue with the example, we'll discuss how arguments are +passed to callouts and information is returned to the server. We will +also discuss how information can be moved between callouts. + +@subsubsection hooksdgCalloutSignature The Callout Signature + +All callouts are declared with the signature: +@code +extern "C" { +int callout(CalloutHandle& handle); +}; +@endcode + +(As before, the callout is declared with "C" linkage.) Information is passed +between BIND 10 and the callout through name/value pairs in the CalloutHandle +object. The object is also used to pass information between callouts on a +per-request basis. (Both of these concepts are explained below.) + +A callout returns an "int" as a status return. A value of 0 indicates +success, anything else signifies an error. The status return has no +effect on server processing; the only difference between a success +and error code is that if the latter is returned, the server will +log an error, specifying both the library and hook that generated it. +Effectively the return status provides a quick way for a callout to log +error information to the BIND 10 logging system. + +@subsubsection hooksdgArguments Callout Arguments + +The CalloutHandle object provides two methods to get and set the +arguments passed to the callout. These methods are called (naturally +enough) getArgument and SetArgument. Their usage is illustrated by the +following code snippets. + +@code + // Server-side code snippet to show the setting of arguments + + int count = 10; + boost::shared_ptr pktptr = ... // Set to appropriate value + + // Assume that "handle" has been created + handle.setArgument("data_count", count); + handle.setArgument("inpacket", pktptr); + + // Call the callouts attached to the hook + ... + + // Retrieve the modified values + handle.getArgument("data_count", count); + handle.getArgument("inpacket", pktptr); +@endcode + +In the callout + +@code + int number; + boost::shared_ptr packet; + + // Retrieve data set by the server. + handle.getArgument("data_count", number); + handle.getArgument("inpacket", packet); + + // Modify "number" + number = ...; + + // Update the arguments to send the value back to the server. + handle.setArgument("data_count", number); +@endcode + +As can be seen "getArgument" is used to retrieve data from the +CalloutHandle, and setArgument used to put data into it. If a callout +wishes to alter data and pass it back to the server, it should retrieve +the data with getArgument, modify it, and call setArgument to send +it back. + +There are several points to be aware of: + +- the data type of the variable in the call to getArgument must match +the data type of the variable passed to the corresponding setArgument +exactly: using what would normally be considered to be a +"compatible" type is not enough. For example, if the server passed +an argument as an "int" and the callout attempted to retrieve it as a +"long", an exception would be thrown even though any value that can +be stored in an "int" will fit into a "long". This restriction also +applies the "const" attribute but only as applied to data pointed to by +pointers, e.g. if an argument is defined as a "char*", an exception will +be thrown if an attempt is made to retrieve it into a variable of type +"const char*". (However, if an argument is set as a "const int", it can +be retrieved into an "int".) The documentation of each hook point will +detail the data type of each argument. +- Although all arguments can be modified, some altered values may not +be read by the server. (These would be ones that the server considers +"read-only".) Consult the documentation of each hook to see whether an +argument can be used to transfer data back to the server. +- If a pointer to an object is passed to a callout (either a "raw" +pointer, or a boost smart pointer (as in the example above), and the +underlying object is altered through that pointer, the change will be +reflected in the server even if no call is made to setArgument. + +In all cases, consult the documentation for the particular hook to see whether +parameters can be modified. As a general rule: + +- Do not alter arguments unless you mean the change to be reflected in +the server. +- If you alter an argument, call CalloutHandle::setArgument to update the +value in the CalloutHandle object. + +@subsubsection hooksdgSkipFlag The "Skip" Flag + +When a to callouts attached to a hook returns, the server will usually continue +its processing. However, a callout might have done something that means that +the server should follow another path. Possible actions a server could take +include: + +- Skip the next stage of processing because the callout has already +done it. For example, a hook is located just before the DHCP server +allocates an address to the client. A callout may decide to allocate +special addresses for certain clients, in which case it needs to tell +the server not to allocate an address in this case. +- Drop the packet and continue with the next request. A possible scenario +is a DNS server where a callout inspects the source address of an incoming +packet and compares it against a black list; if the address is on it, +the callout notifies the server to drop the packet. + +To handle these common cases, the CalloutHandle has a "skip" flag. +This is set by a callout when it wishes the server to skip normal +processing. It is set false by the hooks framework before callouts on a +hook are called. If the flag is set on return, the server will take the +"skip" action relevant for the hook. + +The methods to get and set the "skip" flag are getSkip and setSkip. Their +usage is intuitive: + +@code + // Get the current setting of the skip flag. + bool skip = handle.getSkip(); + + // Do some processing... + : + if (lease_allocated) { + // Flag the server to skip the next step of the processing as we + // already have an address. + handle.setSkip(true); + } + return; + +@endcode + +Like arguments, the "skip" flag is passed to all callouts on a hook. Callouts +later in the list are able to examine (and modify) the settings of earlier ones. + +@subsubsection hooksdgCalloutContext Per-Request Context + +Although many of the BIND 10 modules can be characterised as handling +singles packet - e.g. the DHCPv4 server receives a DISCOVER packet, +processes it and responds with an OFFER, this is not true in all cases. +The principal exception is the recursive DNS resolver: this receives a +packet from a client but that packet may itself generate multiple packets +being sent to upstream servers. To avoid possible confusion the rest of +this section uses the term "request" to indicate a request by a client +for some information or action. + +As well as argument information, the CalloutHandle object can be used by +callouts to attach information to a request being handled by the server. +This information (known as "context") is not used by the server: its purpose +is to allow callouts to pass information between one another on a +per-request basis. + +Context only exists only for the duration of the request: when a request +is completed, the context is destroyed. A new request starts with no +context information. Context is particularly useful in servers that may +be processing multiple requests simultaneously: callouts can effectively +attach data to a request that follows the request around the system. + +Context information is held as name/value pairs in the same way +as arguments, being accessed by the pair of methods setContext and +getContext. They have the same restrictions as the setArgument and +getArgument methods - the type of data retrieved from context must +exactly match the type of the data set. + +The example in the next section illustrates their use. + +@subsection hooksdgExampleCallouts Example Callouts + +Continuing with the tutorial, the requirements need us to retrieve the +hardware address of the incoming packet, classify it, and write it, +together with the assigned IP address, to a log file. Although we could +do this in one callout, for this example we'll use two: + +- pkt_rcvd - a callout on this hook is invoked when a packet has been +received and has been parsed. It is passed a single argument, "query" +which is an isc::dhcp::Pkt4 object (representing a DHCP v4 packet). +We will do the classification here. + +- v4_lease_write_post - called when the lease (an assignment of an IPv4 +address to a client for a fixed period of time) has been written to the +database. It is passed two arguments, the query ("query") +and the response (called "reply"). This is the point at which the +example code will write the hardware and IP addresses to the log file. + +The standard for naming callouts is to give them the same name as +the hook. If this is done, the callouts will be automatically found +by the Hooks system (this is discussed further in section @ref +hooksdgCalloutRegistration). For our example, we will assume this is the +case, so the code for the first callout (used to classify the client's +hardware address) is: + +@code +// pkt_rcvd.cc + +#include +#include +#include "library_common.h" + +#include + +using namespace isc::dhcp; +using namespace std; + +extern "C" { + +// This callout is called at the "pkt_rcvd" hook. +int pkt_rcvd(CalloutHandle& handle) { + + // A pointer to the packet is passed to the callout via a "boost" smart + // pointer. The include file "pkt4.h" typedefs a pointer to the Pkt4 + // object as Pkt4Ptr. Retrieve a pointer to the object. + Pkt4Ptr query_ptr; + handle.getArgument("query", query_ptr); + + // Point to the hardware address. + HwAddrPtr hwaddr_ptr = query_ptr->getHWAddr(); + + // The hardware address is held in a public member variable. We'll classify + // it as interesting if the sum of all the bytes in it is divisible by 4. + // (This is a contrived example after all!) + long sum = 0; + for (int i = 0; i < hwaddr_ptr->hwaddr_.size(); ++i) { + sum += hwaddr_ptr->hwadr_[i]; + } + + // Classify it. + if (sum % 4 == 0) { + // Store the text form of the hardware address in the context to pass + // to the next callout. + handle.setContext("hwaddr", hwaddr_ptr->hwaddr_.toText()); + } + + return (0); +}; +@endcode + +The pct_rcvd callout placed the hardware address of an interesting client in +the "hwaddr" context for the packet. Turning now to the callout that will +write this information to the log file: + +@code +// v4_lease_write.cc + +#include +#include +#include "library_common.h" + +#include + +using namespace isc::dhcp; +using namespace std; + +extern "C" { + +// This callout is called at the "v4_lease_write_post" hook. +int v4_lease_write_post(CalloutHandle& handle) { + + // Obtain the hardware address of the "interesting" client. We have to + // use a try...catch block here because if the client was not interesting, + // no information would be set and getArgument would thrown an exception. + string hwaddr; + try (handle.getArgument("hwaddr", hwaddr) { + + // getArgument didn't throw so the client is interesting. Get a pointer + // to the reply. Note that the argument list for this hook also + // contains a pointer to the query: we don't need to access that in this + // example. + Pkt4Ptr reply; + handle.getArgument("reply", reply); + + // Get the string form of the IP address. + string ipaddr = reply->getYiaddr().toText(); + + // Write the information to the log file. + interesting << hwaddr << " " << ipaddr << "\n"; + + // ... and to guard against a crash, we'll flush the output stream. + flush(interesting); + + } catch (const NoSuchCalloutContext&) { + + // No such element in the per-request context with the name + // "hwaddr". We will do nothing, so just dismiss the exception. + + } + + return (0); +} + +}; +@endcode + +@subsection hooksdgBuild Building the Library + +Building the code requires building a shareable library. This requires +the the code be compiled as positition-independent code (using the +compiler's "-fpic" switch) and linked as a shared library (with the +linker's "-shared" switch). The build command also needs to point to +the BIND 10 include directory and link in the appropriate libraries. + +Assuming that BIND 10 has been installed in the default location, the +command line needed to create the library using the Gnu C++ compiler on a +Linux system is: + +@code +g++ -I /usr/include/bind10 -L /usr/lib/bind10 -fpic -shared -o example.so \ + load_unload.cc pkt_rcvd.cc v4_lease_write.cc version.cc \ + -lb10-dhcp++ -lb10-util -lb10-exceptions +@endcode + +Notes: +- The compilation command and switches required may vary depending on +your operating system and compiler - consult the relevant documentation +for details. +- The values for the "-I" and "-L" switches depend on where you have +installed BIND 10. +- The list of libraries that need to be included in the command line +depends on the functionality used by the hook code and the module to +which they are attached (e.g. hook code for DNS will need to link against +the libb10-dns++ library). Depending on operating system, you may also need +to explicitly list libraries on which the BIND 10 libraries depend. + +@subsection hooksdgConfiguration Configuring the Hook Library + +The final step is to make the library known to BIND 10. All BIND 10 modules to +which hooks can be added contain the "hook_library" element, and user +libraries are added to this. (The BIND 10 hooks system can handle multiple libraries - this is discussed below.). + +To add the example library (assumed to be in /usr/local/lib) to the DHCPv4 +module, the following bindctl commands must be executed: + +@code +> config add Dhcp4/hook_libraries +> config set Dhcp4/hook_libraries[0] "/usr/local/lib/example.so" +> config commit +@endcode + +The DHCPv4 server will load the library and execute the callouts each time a +request is received. + +@section hooksdgAdvancedTopics Advanced Topics + +@subsection hooksdgContextCreateDestroy Context Creation and Destruction + +As well as the hooks defined by the server, the hooks framework defines +two hooks of its own, "context_create" and "context_destroy". The first +is called when a request is created in the server, before any of the +server-specific hooks gets called. It's purpose it to allow a library +to initialize per-request context. The second is called after all +server-defined hooks have been processed, and is to allow a library to +tidy up. + +As an example, the v4_lease_write example above required that the code +check for an exception being thrown when accessing the "hwaddr" context +item in case it was not set. An alternative strategy would have been to +provide a callout for the "context_create" hook and set the context item +"hwaddr" to an empty string. Instead of needing to handle an exception, +v4_lease_write would be guaranteed to get something when looking for +the hwaddr item and so could write or not write the output depending on +the value. + +In most cases, "context_destroy" is not needed as the Hooks system +automatically deletes context. An example where it could be required +is where memory has been allocated by a callout during the processing +of a request and a raw pointer to it stored in the context object. On +destruction of the context, that memory will not be automatically +released. Freeing in the memory in the "context_destroy callout will solve +that problem. + +Actually, when the context is destroyed, the destructor +associated with any objects stored in it are run. Rather than point to +allocated memory with a raw pointer, a better idea would be to point to +it with a boost "smart" pointer and store that pointer in the context. +When the context is destroyed, the smart pointer's destructor is run, +which will automatically delete the pointed-to object. + +These approaches are illustrated in the following examples. +Here it is assumed that the hooks library is performing some form of +security checking on the packet and needs to maintain information in +a user-specified "SecurityInformation" object. (The details of this +fictitious object are of no concern here.) The object is created in +the context_create callout and used in both the pkt4_rcvd and the +v4_lease_write_post callouts. + +@code +// Storing information in a "raw" pointer. Assume that the + +#include + : + +extern "C" { + +// context_create callout - called when the request is created. +int context_create(CalloutHandle& handle) { + // Create the security information and store it in the context + // for this packet. + SecurityInformation* si = new SecurityInformation(); + handle.setContext("security_information", si); +} + +// Callouts that use the context +int pktv_rcvd(CalloutHandle& handle) { + // Retrieve the pointer to the SecurityInformation object + SecurityInformation si; + handle.getContext("security_information", si); + : + : + // Set the security information + si->setSomething(...); + + // The pointed-to information has been updated but the pointer has not been + // altered, so there is no need to call setContext() again. +} + +int v4_lease_write_post(CalloutHandle& handle) { + // Retrieve the pointer to the SecurityInformation object + SecurityInformation si; + handle.getContext("security_information", si); + : + : + // Retrieve security information + bool active = si->getSomething(...); + : +} + +// Context destruction. We need to delete the pointed-to SecurityInformation +// object because we will lose the pointer to it when the CalloutHandle is +// destroyed. +int context_destroy(CalloutHandle& handle) { + // Retrieve the pointer to the SecurityInformation object + SecurityInformation si; + handle.getContext("security_information", si); + + // Delete the pointed-to memory. + delete si; +} +@endcode + +The requirement for the context_destroy callout can be eliminated if +a Boost shared ptr is used to point to the allocated memory: + +@code +// Storing information in a "raw" pointer. Assume that the + +#include +#include + : + +extern "C" { + +// context_create callout - called when the request is created. + +int context_create(CalloutHandle& handle) { + // Create the security information and store it in the context for this + // packet. + boost::shared_ptr si(new SecurityInformation()); + handle.setContext("security_information", si); +} + +// Other than the data type, a shared pointer has similar semantics to a "raw" +// pointer. Only the code from pkt_rcvd is shown here. + +int pktv_rcvd(CalloutHandle& handle) { + // Retrieve the pointer to the SecurityInformation object + boost::shared_ptr si; + handle.setContext("security_information", si); + : + : + // Modify the security information + si->setSomething(...); + + // The pointed-to information has been updated but the pointer has not + // altered, so theree is no need to reset the context. +} + +// No context_destroy callout is needed to delete the allocated +// SecurityInformation object. When the CalloutHandle is destroyed, the shared +// pointer object will be destroyed. If that is the last shared pointer to the +// allocated memory, then it too will be deleted. +@endcode + +(Note that a Boost shared pointer - rather than any other Boost smart pointer - +should be used, as the pointer objects are copied within the hooks framework and +only shared pointers have the correct behavior for the copy operation.) + + +@subsection hooksdgCalloutRegistration Registering Callouts + +As briefly mentioned in @ref hooksdgExampleCallouts, the standard is for +callouts in the user library to have the same name as the name of the +hook to which they are being attached. This convention was followed +in the tutorial, e.g. the callout that needed to be attached to the +"pkt_rcvd" hook was named pkt_rcvd. + +The reason for this convention is that when the library is loaded, the +hook framework automatically searches the library for functions with +the same names as the server hooks. When it finds one, it attaches it +to the appropriate hook point. This simplifies the loading process and +bookkeeping required to create a library of callouts. + +However, the hooks system is flexible in this area: callouts can have +non-standard names, and multiple callouts can be registered on a hook. + +@subsubsection hooksdgLibraryHandle The LibraryHandle Object + +The way into the part of the hooks framework that allows callout +registration is through the LibraryHandle object. This was briefly +introduced in the discussion of the framework functions, in that +an object of this type is pass to the "load" function. A LibraryHandle +can also be obtained from within a callout by calling the CalloutHandle's +getLibraryHandle() method. + +The LibraryHandle provides three methods to manipulate callouts: + +- registerCallout - register a callout on a hook. +- deregisterCallout - deregister a callout from a hook. +- deregisterAllCallouts - deregister all callouts on a hook. + +The following sections cover some of the ways in which these can be used. + +@subsubsection hooksdgNonstandardCalloutNames Non-Standard Callout Names + +The example in the tutorial used standard names for the callouts. As noted +above, it is possible to use non-standard names. Suppose, instead of the +callout names "pkt_rcvd" and "v4_lease_write", we had named our callouts +"classify" and "write_data". The hooks framework would not have registered +these callouts, so we would have needed to do it ourself. The place to +do this is the "load" framework function, and its code would have had to +been modified to: + +@code +int load(LibraryHandle& libhandle) { + // Register the callouts on the hooks. We assume that a header file + // declares the "classify" and "write_data" functions. + libhandle.registerCallout("pkt_rcvd", classify); + libhandle.registerCallout("v4_lease_write", write_data); + + // Open the log file + interesting.open("/data/clients/interesting.log", + std::fstream::out | std::fstream::app); + return (interesting ? 0 : 1); +} +@endcode + +It is possible for a library to contain callouts with both standard and +non-standard names: ones with standard names will be registered automatically, +ones with non-standard names need to be registered manually. + +@subsubsection hooksdgMultipleCallouts Multiple Callouts on a Hook + +The BIND 10 hooks framework allows multiple callouts to be attached to +a hook point. Although it is likely to be rare for user code to need to +do this, there may be instances where it make sense. + +To register multiple callouts on a hook, just call +LibraryHandle::registerCallout multiple times on the same hook, e.g. + +@code + libhandle.registerCallout("pkt_rcvd", classify); + libhandle.registerCallout("pkt_rcvd", write_data); +@endcode + +The hooks framework will call the callouts in the order they are +registered. The same CalloutHandle is passed between them, so any +change made to the CalloutHandle's arguments, "skip" flag, or per-request +context by the first is visible to the second. + +@subsubsection hooksdgDynamicRegistration Dynamic Registration and Reregistration of Callouts + +The previous sections have dealt with callouts being registered during +the call to "load". The hooks framework is more flexible than that +in that callouts can be registered and deregistered within a callout. +In fact, a callout is able to register or deregister itself, and a callout +is able to be registered on a hook multiple times. + +Using our contrived example again, the DHCPv4 server processes one request +to completion before it starts processing the next. With this knowledge, +we could alter the logic of the code so that the callout attached to the +"pkt_rcvd" hook registers the callout doing the logging when it detects +an interesting packet, and the callout doing the logging deregisters +itself in its execution. The relevant modifications to the code in +the tutorial are shown below: + +@code +// pkt_rcvd.cc +// : + +int pkt_rcvd(CalloutHandle& handle) { + + : + : + + // Classify it. + if (sum % 4 == 0) { + // Store the text form of the hardware address in the context to pass + // to the next callout. + handle.setContext("hwaddr", hwaddr_ptr->hwaddr_.toText()); + + // Register the callback to log the data. + handle.getLibraryHandle().registerCallout("v4_lease_write", write_data); + } + + return (0); +}; +@endcode + +@code +// v4_lease_write.cc + : + +int write_data(CalloutHandle& handle) { + + // Obtain the hardware address of the "interesting" client. As the + // callback is only registered when interesting data is present, we + // know that the context contains the hardware address so an exception + // will not be thrown when we call getArgument(). + string hwaddr; + handle.getArgument("hwaddr", hwaddr); + + // The pointer to the reply. + ConstPkt4Ptr reply; + handle.getArgument("reply", reply); + + // Get the string form of the IP address. + string ipaddr = reply->getYiaddr().toText(): + + // Write the information to the log file and flush. + interesting << hwaddr << " " << ipaddr << "\n"; + flush(interesting); + + // We've logged the data, so deregister ourself. This callout will not + // be called again until it is registered by pkt_rcvd. + + handle.getLibraryHandle().deregisterCallout("v4_lease_write", write_data); + + return (0); +} +@endcode + +Note that the above example used a non-standard name for the callout +that wrote the data. Had the name been a standard one, it would have been +registered when the library was loaded and called for the first request, +regardless of whether that was defined as "interesting". (Although as +callouts with standard names are always registered before "load" gets called, +we could have got round that problem by deregistering that particular +callout in the "load" function.) + + +@note Deregistration of a callout on the hook that is currently +being called only takes effect when the server next calls the hook. +To illustrate this, suppose the callouts attached to a hook are A, B and C +(in that order), and during execution, A deregisters B and C and adds D. +When callout A returns, B and C will still run. The next time the server +calls the hook's callouts, A and D will run (in that order). + +@subsection hooksdgMultipleLibraries Multiple User Libraries + +As alluded to in the section @ref hooksdgConfiguration, BIND 10 can load +multiple libraries. The libraries are loaded in the order specified in +the configuration, and the callouts attached to the hooks in the order +presented by the libraries. + +The following picture illustrates this, and also illustrates the scope of +data passed around the system. + +@image html DataScopeArgument.png "Scope of Arguments" + +In this illustration, a server has three hook points, alpha, beta +and gamma. Two libraries are configured, library 1 and library 2. +Library 1 registers the callout "authorize" for hook alpha, "check" for +hook beta and "add_option" for hook gamma. Library 2 registers "logpkt", +"validate" and "putopt" + +The horizontal red lines represent arguments to callouts. When the server +calls hook alpha, it creates an argument list and calls the +first callout for the hook, "authorize". When that callout returns, the +same (but possibly modified) argument list is passed to the next callout +in the chain, "logpkt". Another, separate argument list is created for +hook beta and passed to the callouts "check" and "validate" in +that order. A similar sequence occurs for hook gamma. + +The next picture shows the scope of the context associated with a +request. + +@image html DataScopeContext.png "Illustration of per-library context" + +The vertical blue lines represent callout context. Context is +per-packet but also per-library. When the server calls "authorize", +the CalloutHandle's getContext and setContext methods access a context +created purely for library 1. The next callout on the hook will access +context created for library 2. These contexts are passed to the callouts +associated with the next hook. So when "check" is called, it gets the +context data that was set by "authorize", when "validate" is called, +it gets the context data set by "logpkt". + +It is stressed that the context for callouts associated with different +libraries is entirely separate. For example, suppose "authorize" sets +the CalloutHandle's context item "foo" to 2 and "logpkt" sets an item of +the same name to the string "bar". When "check" accesses the context +item "foo", it gets a value of 2; when "validate" accesses an item of +the same name, it gets the value "bar". + +It is also stressed that all this context exists only for the life of the +request being processed. When that request is complete, all the +context associated with that request - for all libraries - is destroyed, +and new context created for the next request. + +This structure means that library authors can use per-request context +without worrying about the presence of other libraries. Other libraries +may be present, but will not affect the context values set by a library's +callouts. + +@subsection hooksdgInterLibraryData Passing Data Between Libraries + +In rare cases, it is possible that one library may want to pass +data to another. This can be done in a limited way by means of the +CalloutHandle's setArgument and getArgument calls. For example, in the +above diagram, the callout "add_option" can pass a value to "putopt" +by setting a name.value pair in the hook's argument list. "putopt" +would be able to read this, but would not be able to return information +back to "add_option". + +All argument names used by BIND 10 will be a combination of letters +(both upper- and lower-case), digits, hyphens and underscores: no +other characters will be used. As argument names are simple strings, +it is suggested that if such a mechanism be used, the names of the data +values passed between the libraries include a special character such as +the dollar symbol or percent sign. In this way there is no danger that +a name will conflict with any existing or future BIND 10 argument names. + + +@subsection hooksdgRegisterMultipleLibraries Dynamic Callout Registration and Multiple Libraries + +On a particular hook, callouts are called in the order the libraries appear +in the configuration and, within a library, in the order the callouts +are registered. + +This order applies to dynamically-registered callouts as well. As an +example, consider the diagram above where for hook "beta", callout "check" +is followed by callout "validate".

Great! This page will explain how to contribute your +changes and not get disappointed in the process. + +Before you start working on a patch or new feature, it is a good idea +to discuss it first with BIND10 developers. You can post your +questions to bind10-dev +(https://lists.isc.org/mailman/listinfo/bind10-dev) for general BIND10 +stuff or to bind10-dhcp +(https://lists.isc.org/mailman/listinfo/bind10-dhcp) for DHCP specific +topics. If you prefer to get faster feedback, most BIND10 developers +hang out at bind10 jabber room +(xmpp:bind10@conference.jabber.isc.org). Those involved in DHCP also +use dhcp chatroom (xmpp:dhcp@conference.jabber.isc.org). Feel free to +drop a note. It is possible that someone else is working on your +specific issue or perhaps the solution you plan to implement is not +the best one. Often having 10 minutes talk could save many hours of +engineering work. + +Ok, so you have a patch? Great! Before you submit it, make sure that +your code compiles. This may seem obvious, but it there's more to +it. I'm sure you have checked that it compiles on your system, but +BIND10 is a portable software. Besides Linux, it is being compiled on +relatively uncommon systems, like OpenBSD or Solaris 11. Will your +code compile there? Will it work? What about endianess? It is likely +that you used regular x86, but the software is expected to run on many +other architectures. + +Have your patch conforms to BIND10 +http://bind10.isc.org/wiki/CodingGuidelines? You still can submit +a patch that does not adhere to it, but it will decrease your +chances of being accepted. If the deviations are minor, ISC engineer +that will do the review, will likely fix the issues. However, +if there are lots of them, reviewer may simply reject the patch +and ask you to fix it, before resubmitting. + +One of the ground rules in BIND10 development is that every piece of +code has to be tested. We now have an extensive set of unit-tests for +almost every line of code. Even if you are fixing something small, +like a single line fix, it is encouraged to write unit-test for that +change. That is even more true for new code. If you write a new +function, method or a class, you definitely should write unit-tests +for it. + +BIND10 uses google test (gtest) framework as a base for our +unit-tests. See http://code.google.com/p/googletest/ for details. +You must have gtest installed or at least compiled before compiling +BIND10 unit-tests. To enable unit-tests in BIND10 + +./configure --with-gtest=/path/to/your/gtest/dir + +or + +./configure --with-gtest-source=/path/to/your/gtest/dir + +Depending on how you compiled or installed (e.g. from sources or using +some package management system) one of those two switches will find +gtest. After that you make run unit-tests: + +make check + +If you happen to add new files or modified Makefiles, it is also a +good idea to check if you haven't broken distribution process: + +make distcheck + +Once all those are checked and working, feel free to create a ticket +for your patch (http://bind10.isc.org) or attach your patch to the +existing ticket if there is one. You may drop a note to bind10 or dhcp +chatroom saying that you have submitted a patch. Alternatively, you +may send a note to bind10-dev or bind10-dhcp lists. + +Here's the tricky part. One of BIND10 developers will review your +patch, but it may not happen immediately. Unfortunately, developers +are usually working under tight schedule, so any extra unplanned +review work sometimes make take a while. Having said that, we value +external contributions very much and will do whatever we can to +review patches in a timely manner. Don't get discouraged if your +patch is not accepted after first review. To keep the code quality +high, we use the same review processes for internal code and for +external patches. It may take several cycles of review/updated patch +submissions before the code is finally accepted. + +Once the process is almost completed, the developer will likely ask +you how you would like to be credited. The typical answers are by +first,last name, by nickname, by company or anonymously. Typically we +will add a note to ChangeLog. If the contributted feature is big or +critical for whatever reason, it may be also mentioned in release +notes. + +*/ \ No newline at end of file diff --git a/doc/devel/mainpage.dox b/doc/devel/mainpage.dox index c670eaf140..6335264096 100644 --- a/doc/devel/mainpage.dox +++ b/doc/devel/mainpage.dox @@ -33,6 +33,9 @@ * you should read BIND10 * Guide (Administrator Reference for BIND10) instead. * + * @section contrib Contributor's Guide + * - @subpage contributorGuide + * * Regardless of your field of expertise, you are encouraged to visit * BIND10 webpage (http://bind10.isc.org) * @section hooksFramework Hooks Framework -- cgit v1.2.3 From 1932ac5a9ffb435e2875f9e921beb486e2be8f4e Mon Sep 17 00:00:00 2001 From: Mukund Sivaraman Date: Wed, 21 Aug 2013 08:42:13 +0530 Subject: [2857] Fix typo --- src/bin/memmgr/memmgr.py.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/bin/memmgr/memmgr.py.in b/src/bin/memmgr/memmgr.py.in index 717050b397..e6748b4197 100755 --- a/src/bin/memmgr/memmgr.py.in +++ b/src/bin/memmgr/memmgr.py.in @@ -140,7 +140,7 @@ class Memmgr(BIND10Server): notifications = None with self._builder_lock: # Copy the notifications out and clear them from the - # original list.

Using a state driven implementation accounts +/// for the conditional processing flow necessary to meet the DDNS RFCs as well +/// as the asynchronous nature of IO with DNS servers. +/// +/// Derivations of the class are responsible for defining the state model and +/// conversations necessary to carry out the specific of request. +/// +/// Conversations with DNS servers are done through the use of the DNSClient +/// class. The DNSClient provides a IOService-based means a service which +/// performs a single, packet exchange with a given DNS server. It sends a +/// single update to the server and returns the response, asynchronously, +/// through a callback. At each point in a transaction's state model, where +/// an update is to be sent, the model "suspends" until notified by the +/// DNSClient via the callback. +/// +/// The state model implementation used is a very basic approach. States +/// and events are simple integer constants. Each state must have a state +/// handler. State handlers are void methods which accept an event as their +/// only parameter. Each transaction instance contains a map of states to +/// to bound method pointers to their respective state handlers. +/// +/// When invoked, the handler determines what it should do based upon the event, +/// including what the next state and event should be. In other words the state +/// transition knowledge is distributed among the state handlers rather than +/// encapsulated in some form of state transition table. Events set from within +/// the state handlers are "internally" triggered events. Events set from +/// outside the state model, such as through the DNSClient completion callback +/// are "externally" triggered. +/// +/// Executing the model consists of iteratively invoking the state handler +/// indicated by the current state and passing it the current event. As the +/// handlers update the state and event, the machine is traversed. The loop +/// "stops" whenever the model cannot continue without an externally triggered +/// event or when it has reached its final state. In the case of the former, +/// the loop is re-entered upon arrival of the external event. +/// +/// This loop is implemented in the runStateModel method. This method accepts +/// an event as argument. This event is treated as the "next event" to process +/// and is fed to the current state's handler. The runStateModel does not exit +/// until a handler sets the next event to a special value, NOP_EVT, +/// indicating that either it is now waiting for IO to complete of the state +/// model has reached its conclusion. +/// +/// Re-entering the "loop" when a DNS update completes is done by a call to +/// runStateModel() from within the DNSClient callback, with an event value +/// of IO_COMPLETED_EVT. As above, runStateModel() will loop until either the +/// next IO is issued or the state model has reached its conclusion. +/// +/// This class defines a set of events and states that are a common to all +/// transactions.

States +/// and events are simple integer constants. Each state must have a state +/// handler. State handlers are void methods which require no parameters. +/// Each model instance contains a map of states to instance method pointers +/// to their respective state handlers. The model tracks the following +/// context values: +/// +/// * state - The current state of the model +/// * previous state - The state the model was in prior to the current state +/// * next event - The next event to be consumed +/// * last event - The event most recently consumed +/// +/// When invoked, a state handler determines what it should do based upon the +/// next event including what the next state and event should be. In other +/// words the state transition knowledge is distributed among the state +/// handlers rather than encapsulated in some form of state transition table. +/// +/// Events "posted" from within the state handlers are "internally" triggered +/// events. Events "posted" from outside the state model, such as through +/// the invocation of a callback are "externally" triggered. +/// +/// StateModel defines two states: +/// +/// * NEW_ST - State that a model is in following instantiation. It remains in +/// this state until model execution has begun. +/// * END_ST - State that a model is in once it has reached its conclusion. +/// +/// and the following events: +/// +/// * START_EVT - Event used to start model execution. +/// * NOP_EVT - Event used to signify that the model stop and wait for an +/// external event, such as the completion of an asynchronous IO operation. +/// * END_EVT - Event used to trigger a normal conclusion of the model. This +/// means only that the model was traversed from start to finish, without any +/// model violations (i.e. invalid state, event, or transition) or uncaught +/// exceptions. +/// * FAIL_EVT - Event to trigger an abnormal conclusion of the model. This +/// event is posted internally when model execution fails due to a model +/// violation or uncaught exception. It signifies that the model has reached +/// an inoperable condition. +/// +/// Derivations add their own states and events appropriate for their state +/// model. Note that NEW_ST and END_ST do not support handlers. No work can +/// done (events consumed) prior to starting the model nor can work be done +/// once the model has ended. +/// +/// Model execution consists of iteratively invoking the state handler +/// indicated by the current state which should consume the next event. As the +/// handlers post events and/or change the state, the model is traversed. The +/// loop stops whenever the model cannot continue without an externally +/// triggered event or when it has reached its final state. In the case of +/// the former, the loop may be re-entered upon arrival of the external event. +/// +/// This loop is implemented in the runModel method. This method accepts an +/// event as argument which is "posts" as the next event. It then retrieves the +/// handler for the current state from the handler map and invokes it. runModel +/// repeats this process until it either NOP_EVT or END_EVT events are posted. +/// In other words each invocation of runModel causes the model to be traversed +/// from the current state until it must wait or ends . +/// +/// Re-entering the "loop" upon the occurrence of an external event is done by +/// invoking runModel with the appropriate event. As before, runModel will +/// loop until either the NOP_EVT occurs or until the model reaches its end. +/// +/// A StateModel (derivation) is in the NEW_ST when constructed and remains +/// there until it has been "started". Starting the model is done by invoking +/// the startModel method which accepts a state as a parameter. This parameter +/// specifies the "start" state and it becomes the current state. + +/// The first task undertaken by startModel is to initialize and verify the +/// state handler map. Two virtual methods, initializeStateHandlerMap and +/// verifyStateHandlerMap, are provided for the express purpose of allowing +/// derivations to populate the state handler map and then verify that map is +/// contents are correct. +/// +/// Once the handler map has been properly initialized, the startModel method +/// invokes runModel with an event of START_EVT. From this point forward and +/// until the model reaches the END_ST or fails, it is considered to be +/// "running". If the model encounters a NOP_EVT then it is "running" and +/// "waiting". If the model reaches END_ST with an END_EVT it is considered +/// "done". If the model fails (END_ST with a FAILED_EVT) it is considered +/// "done" and "failed". There are several boolean status methods which may +/// be used to check these conditions. +/// +/// To progress from from one state to the another, state handlers invoke use +/// the method, transition. This method accepts a state and an a event as +/// parameters. These values become the current state and the next event +/// respectively. This has the effect of entering the given state having posted +/// the given event. The postEvent method is may be used to post a new event +/// to the current state. +/// +/// Bringing the model to a normal end is done by invoking the endModel method +/// which transitions the model to END_ST with END_EVT.

Since both CalloutHandle + and CalloutManager are created in the statically-linked BIND 10 server, + use of the reference means that it is the singleton within the server - + and not the one within the user's hooks library - that is referenced. + + The solution of the logging problem is not so straightforward. Within + BIND 10, there are two logging components, the BIND 10 logging framework + and the log4cplus libraries. Owing to static linking, there are two + instances of the former; but as static linking uses shared libraries of + third-party products, there is one instance of the latter. What further + complicates matters is that initialization of the logging framework is + in two parts: static initialization and run-time initialization. + + The logging initialization comprises the following: + + -# Static initialization of the log4cplus global variables. + -# Static initialization of messages in the various BIND 10 libraries. + -# Static initialization of logging framework. + -# Run-time initialization of the logging framework. + -# Run-time initialization of log4cplus + + As both the BIND 10 server and the user-written hooks libraries use the + log4cplus shared library, item 1 - the static initialization of the log4cplus + global variables is performed once. + + The next two tasks - static initialization of the messages in the BIND + 10 libraries and the static initialization of the logging framework + - is performed twice, once in the context of the BIND 10 server and + once in the context of the hooks library. For this reason, run-time + initialization of the logging framework needs to be performed twice, + once in the context of the BIND 10 server and once in the context of the + user-written hooks library. However, the standard logging framework + initialization code also performs the last task, initialization of + log4cplus, something that causes problems if executed more than once. + + To get round this, the function isc::hooks::hooksStaticLinkInit() + has been written. It executes the only part of the logging framework + run-time initialization that actually pertains to the logging framework + and not log4cplus, namely loading the message dictionary with the + statically-initialized messages in the BIND 10 libraries. + This should be executed by any hooks library linking against a statically + initialized BIND 10. (In fact, running it against a dynamically-linked + BIND 10 should have no effect, as the load operation discards any duplicate + message entries.) The hooks library tests do this, the code being + copnditionally compiled within a test of the USE_STATIC_LINK macro, set + by the configure script. + + @note Not everything is completely rosy with logging and static linking. + In particular, there appears to be an issue with the scenario where a + user-written hooks library is run by a statically-linked BIND 10 and then + unloaded.

However, both methods are +kept, because increaseAddress() is faster and this is a routine that may be +called many hundred thousands times per second. + */ -- cgit v1.2.3 From e09660860573d1b76c65a200d3682d3592406b67 Mon Sep 17 00:00:00 2001 From: Tomek Mrugalski Date: Tue, 24 Sep 2013 11:25:55 +0200 Subject: [3171] alloc{Address -> Lease} rename, compilation fixes --- src/bin/dhcp4/dhcp4_srv.cc | 10 ++-- src/bin/dhcp4/tests/dhcp4_srv_unittest.cc | 18 +++---- src/bin/dhcp6/dhcp6_srv.cc | 14 ++--- src/bin/dhcp6/tests/dhcp6_srv_unittest.cc | 56 ++++++++++++-------- src/bin/dhcp6/tests/dhcp6_test_utils.h | 3 +- src/bin/dhcp6/tests/hooks_unittest.cc | 12 ++--- src/lib/dhcpsrv/alloc_engine.cc | 32 +++++------- src/lib/dhcpsrv/alloc_engine.h | 32 +++++------- src/lib/dhcpsrv/tests/alloc_engine_unittest.cc | 72 +++++++++++++------------- 9 files changed, 123 insertions(+), 126 deletions(-) diff --git a/src/bin/dhcp4/dhcp4_srv.cc b/src/bin/dhcp4/dhcp4_srv.cc index 7d13631bb3..edd9af435c 100644 --- a/src/bin/dhcp4/dhcp4_srv.cc +++ b/src/bin/dhcp4/dhcp4_srv.cc @@ -718,11 +718,11 @@ Dhcpv4Srv::assignLease(const Pkt4Ptr& question, Pkt4Ptr& answer) { // be inserted into the LeaseMgr as well. // @todo pass the actual FQDN data.

+ Echoing client-id (RFC6842) + Original DHCPv4 spec (RFC2131) states that the DHCPv4 server must not + send back client-id options when responding to clients. However, in some cases + that confused clients that did not have MAC address or client-id. See RFC6842 + for details. That behavior has changed with the publication of RFC6842 which + updated RFC2131. That update now states that the server must send client-id. + That is the default behaviour that Kea offers. However, in some cases older + devices that do not support RFC6842 may refuse to accept responses that include + client-id options. To enable backward compatibility, an optional flag has been + introduced. To configure it, use the following commands: + + +> config add Dhcp4/echo-client-id +> config set Dhcp4/echo-client-id True" +> config commit + + +

An obvious drawback of this approach is that the server's +response will be received and processed by all clients in the particular +network. Therefore, the preferred approach is that the server unicasts its +response to a new address being assigned for the client. This client will +identify itself as a target of this message by checking chaddr and/or +Client Identifier value. In the same time, the other clients in the network +will not receive the unicast message. The major problem that arises with this +approach is that the client without an IP address doesn't respond to ARP +messages. As a result, server's response will not be sent over IP/UDP +socket because the system kernel will fail to resolve client's link-layer +address. + +Kea supports the use of raw sockets to create a complete Data-link/IP/UDP/DHCPv4 +stack. By creating each layer of the outgoing packet, the Kea logic has full +control over the frame contents and it may bypass the use of ARP to inject the +link layer address into the frame. The raw socket is bound to a specific interface, +not to the IP address/UDP port. Therefore, the system kernel doesn't have +means to verify that Kea is listening to the DHCP traffic on the specific address +and port. This has two major implications: +- It is possible to run another DHCPv4 sever instance which will bind socket to the +same address and port. +- An attempt to send a unicast message to the DHCPv4 server will result in ICMP +"Port Unreachable" message being sent by the kernel (which is unaware that the +DHCPv4 service is actually running). +In order to overcome these issues, the isc::dhcp::PktFilterLPF opens a +regular IP/UDP socket which coexists with the raw socket. The socket is referred +to as "fallback socket" in the Kea code. All packets received through this socket +are discarded. + +In general, the use of datagram sockets is preferred over raw sockets. +For convenience, the switchable Packet Filter objects are used to manage +sockets for different purposes. These objects implement the socket opening +operation and sending/receiving messages over this socket. For example: +the isc::dhcp::PktFilterLPF object opens a raw socket. +The isc::dhcp::PktFilterLPF::send and isc::dhcp::PktFilterLPF::receive +methods encode/decode full data-link/IP/UDP/DHCPv4 stack. The +isc::dhcp::PktFilterInet supports sending and receiving messages over +the regular IP/UDP socket.

I then measured the max response throughput using a +queryperf-like tool. In both cases Q2 is about 28% of Q1 (I'm not +showing specific numbers to avoid unnecessary discussion about +specific performance of existing servers; it's out of scope of this +memo). Using Q2 = 0.28*Q1, above equation with 90% cache hit rate +will be: A = 0.9 * 0.28 / (0.9*0.28 + 0.1) = 0.716. So the server will +spend about 72% of its running time to answer queries directly from +the cache. + +Of course, these experimental results are too simplified. First, in +these experiments we assumed only one external query is needed on +cache miss. In general it can be more; however, it may not actually +be too optimistic either: in my another research result: +http://bind10.isc.org/wiki/ResolverPerformanceResearch +In the more detailed analysis using real query sample and tracing what +an actual resolver would do, it looked we'd need about 1.44 to 1.63 +external queries per cache miss in average. + +Still, of course, the real world cases are not that simple: in reality +we'd need to deal with timeouts, slower remote servers, unexpected +intermediate results, etc. DNSSEC validating resolvers will clearly +need to do more work. + +So, in the real world deployment Q2 should be much smaller than Q1. +Here are some specific cases of the relationship between Q1 and Q2 for +given A (assuming r = 0.9): + +70%: Q2 = 0.26 * Q1 +60%: Q2 = 0.17 * Q1 +50%: Q2 = 0.11 * Q1 + +So, even if "recursive resolution is 10 times heavier" than the cache +only case, we can assume the server spends a half of its run time for +answering queries directly from the cache at the cache hit rate of +90%. I think this is a reasonably safe assumption. + +Now, assuming the number of 50% or more, does this suggest we should +highly optimize the cache? Opinions may vary on this point, but I +personally think the answer is yes. I've written an experimental +cache only implementation that employs the idea of fully-rendered +cached data. On one test machine (2.20GHz AMD64, using a single +core), queryperf-like benchmark shows it can handle over 180Kqps, +while BIND 9.9.2 can just handle 41K qps. The experimental +implementation skips some necessary features for a production server, +and cache management itself is always inevitable bottleneck, so the +production version wouldn't be that fast, but it still suggests it may +not be very difficult to reach over 100Kqps in production environment +including recursive resolution overhead. + +Cache Types +----------- + +1. Record cache + +Conceptually, any recursive resolver (with cache) implementation would +have cache for RRs (or RRsets in the modern version of protocol) given +in responses to its external queries. In BIND 9, it's called the +"cached DB", using an in-memory rbt-like tree. unbound calls it +"rrset cache", which is implemented as a hash table. + +2. Delegation cache + +Recursive server implementations would also have cache to determine +the deepest zone cut for a given query name in the recursion process. +Neither BIND 9 nor unbound has a separate cache for this purpose; +basically they try to find an NR RRset from the "record cache" whose +owner name best matches the given query name. + +3. Remote server cache + +In addition, a recursive server implementation may maintain a cache +for information of remote authoritative servers. Both BIND 9 and +unbound conceptually have this type of cache, although there are some +non-negligible differences in details. BIND 9's implementation of +this cache is called ADB. Its a hash table whose key is domain name, +and each entry stores corresponding IPv6/v4 addresses; another data +structure for each address stores averaged RTT for the address, +lameness information, EDNS availability, etc. unbound's +implementation is called "infrastructure cache". It's a hash table +keyed with IP addresses whose entries store similar information as +that in BIND 9's per address ADB entry. In unbound a remote server's +address must be determined by looking up the record cache (rrset cache +in unbound terminology); unlike BIND 9's ADB, there's no direct +shortcut from a server's domain name to IP addresses. + +4. Full response cache + +unbound has an additional cache layer, called the "message cache". +It's a hash table whose hash key is query parameter (essentially qname +and type) and entry is a sequence to record (rrset) cache entries. +This sequence constructs a complete response to the corresponding +query, so it would help optimize building a response message skipping +the record cache for each section (answer/authority/additional) of the +response message. PowerDNS recursor has (seemingly) the same concept +called "packet cache" (but I don't know its implementation details +very much). + +BIND 9 doesn't have this type of cache; it always looks into the +record cache to build a complete response to a given query. + +Miscellaneous General Requirements +---------------------------------- + +- Minimize contention between threads (if threaded) +- Cache purge policy: normally only a very small part of cached DNS + information will be reused, and those reused are very heavily + reused. So LRU-like algorithm should generally work well, but we'll + also need to honor DNS TTL. + +Random Ideas for BIND 10 +------------------------ + +Below are specific random ideas for BIND 10. Some are based on +experimental results with reasonably realistic data; some others are +mostly a guess. + +1. Fully rendered response cache + +Some real world query samples show that a very small portion of entire +queries are very popular and queried very often and many times; the +rest is rarely reused, if any. Two different data sets show top +10,000 queries would cover around 80% of total queries, regardless +of the size of the total queries. This suggests an idea of having a +small, highly optimized full response cache. + +I tried this idea in the jinmei-l1cache branch. It's a hash table +keyed with a tuple of query name and type whose entry stores fully +rendered, wire-format response image (answer section only, assuming +the "minimal-responses" option). It also maintains offsets to each +RR, so it can easily update TTLs when necessary or rotate RRs if +optionally requested. If neither TTL adjustment nor RR rotation is +required, query handling is just to lookup the hash table and copy the +pre-rendered data. Experimental benchmark showed it ran vary fast; +more than 4 times faster than BIND 9, and even much faster than other +implementations that have full response cache (although, as usual, the +comparison is not entirely fair). + +Also, the cache size is quite small; the run time memory footprint of +this server process was just about 5MB. So, I think it's reasonable +to have each process/thread have their own copy of this cache to +completely eliminate contention. Also, if we can keep the cache size +this small, it would be easier to dump it to a file on shutdown and +reuse it on restart. This will be quite effective (if the downtime is +reasonably short) because the cached data are expected to be highly +popular. + +2. Record cache + +For the normal record cache, I don't have a particular idea beyond +something obvious, like a hash table to map from query parameters to +corresponding RRset (or negative information). But I guess this cache +should be shared by multiple threads. That will help reconstruct the +full response cache data on TTL expiration more efficiently. And, if +shared, the data structure should be chosen so that contention +overhead can be minimized. In general, I guess something like hash +tables is more suitable than tree-like structure in that sense. + +There's other points to discuss for this cache related to other types +of cache (see below). + +3. Separate delegation cache + +One thing I'm guessing is that it may make sense if we have a separate +cache structure for delegation data. It's conceptually a set of NS +RRs so we can identify the best (longest) matching one for a given +query name. + +Analysis of some sets of query data showed the vast majority of +end client's queries are for A and AAAA (not surprisingly). So, even +if we separate this cache from the record cache, the additional +overhead (both for memory and fetch) will probably (hopefully) be +marginal. Separating caches will also help reduce contention between +threads. It *might* also help improve lookup performance because this +can be optimized for longest match search. + +4. Remote server cache without involving the record cache + +Likewise, it may make sense to maintain the remote server cache +separately from the record cache. I guess these AAAA and A records +are rarely the queried by end clients, so, like the case of delegation +cache it's possible that the data sets are mostly disjoint. Also, for +this purpose the RRsets don't have to have higher trust rank (per +RFC2181 5.4.1): glue or additional are okay, and, by separating these +from the record cache, we can avoid accidental promotion of these data +to trustworthy answers and returning them to clients (BIND 9 had this +type of bugs before). + +Custom vs Existing Library (STL etc) +------------------------------------ + +It may have to be discussed, but I guess in many cases we end up +introducing custom implementation because these caches should be +highly performance sensitive, directly related our core business, and +also have to be memory efficient. But in some sub components we may +be able to benefit from existing generic libraries. diff --git a/doc/design/resolver/03-cache-algorithm.txt b/doc/design/resolver/03-cache-algorithm.txt deleted file mode 100644 index 4aacc4d86c..0000000000 --- a/doc/design/resolver/03-cache-algorithm.txt +++ /dev/null @@ -1,256 +0,0 @@ -03-cache-algorithm - -Introduction ------------- -Cache performance may be important for the resolver.

Reed" Date: Tue, 21 Jan 2014 11:58:56 -0600 Subject: [master] portability fix and unset werror_ok fix This is for ticket 2945. Don't use grep -q (not portable).
