This is a rather large mechanical commit that splits up the memory types
defined in lib/memtypes.c and distributes them into *_memory.[ch] files
in the individual daemons.
The zebra change is slightly annoying because there is no nice place to
put the #include "zebra_memory.h" statement.
bgpd, ospf6d, isisd and some tests were reusing MTYPEs defined in the
library for its own use. This is bad practice and would break when the
memtype are made static.

Added a default log file named /var/log/quagga/Quagga.log to every daemon
to capture log entries if no log file is defined. This also allows the
capture of logged information prior to reading each daemon's config file.
If a log file is defined manually, it will override this default file name.

Introduce a new command "[no] allow-ecmp" to enable/disable the
ECMP feature in RIPng. By default, ECMP is not allowed.
Once ECMP is disabled, only one route entry can exist in the list.
* ripng_zebra.c: adjust a debugging information, which shows the number
of nexthops according to whether ECMP is enabled.
* ripngd.c: ripng_ecmp_add() will reject the new route if ECMP is not
allowed and some entry already exists.
A new configurable command "allow-ecmp" is added to control
whether ECMP is allowed.
When ECMP is disabled, ripng_ecmp_disable() is called to
remove the multiple nexthops.
* ripngd.h: Add a new member "ecmp" to "struct ripng", indicating whether
ECMP is allowed or not.

* Each node in the routing table is changed into a list, holding
the multiple equal-cost paths.
* If one of the multiple entries gets less-preferred (greater
metric or greater distance), it will be directly deleted instead
of starting a garbage-collection timer for it.
The garbage-collection timer is started only when the last entry
in the list gets INFINITY.
* Some new functions are used to maintain the ECMP list. And hence
ripng_route_process(), ripng_redistribute_add() and ripng_timeout()
are significantly simplified.
* ripng_zebra_ipv6_add() and ripng_zebra_ipv6_delete() now can share
the common code. The common part is moved to ripng_zebra_ipv6_send().

In the 90ies, IPv4 was believed to exist within IPv6, with some kernels
implementing this belief in code... Our code here is keyed to "#ifdef
LINUX", yet no Linux from the past 10 years had this, making the code
completely useless.
FreeBSD 10.0 does in fact have a "::/96 via ::1 dev lo0 reject" route.
IMHO we shouldn't mess with that, the admin can filter as neccessary
anyway.

startups. As such refactor the code to allow us to
allow end users to easily switch between the two
sysV:
edit the /etc/quagga/daemons file
service quagga [start|stop|reload|restart]
Systemd:

Several routing protocols use the zapi_ipv[4|6] api to talk to
zebra. There are some instances where the api.vrf_id was not
being set. Since the practice is to declare the api structure
on the stack, the data inside is not being set to 0. As
such random vrf_id values were being passed to zebrad
causing rage and confusion.

The API messages are used by zebra to exchange the interfaces, addresses,
routes and router-id information with its clients. To distinguish which
VRF the information belongs to, a new field "VRF ID" is added in the
message header. And hence the message version is increased to 3.
* The new field "VRF ID" in the message header:
Length (2 bytes)
Marker (1 byte)
Version (1 byte)
VRF ID (2 bytes, newly added)
Command (2 bytes)
- Client side:
- zclient_create_header() adds the VRF ID in the message header.
- zclient_read() extracts and validates the VRF ID from the header,
and passes the VRF ID to the callback functions registered to
the API messages.
- All relative functions are appended with a new parameter "vrf_id",
including all the callback functions.
- "vrf_id" is also added to "struct zapi_ipv4" and "struct zapi_ipv6".
Clients need to correctly set the VRF ID when using the API
functions zapi_ipv4_route() and zapi_ipv6_route().
- Till now all messages sent from a client have the default VRF ID
"0" in the header.
- The HELLO message is special, which is used as the heart-beat of
a client, and has no relation with VRF. The VRF ID in the HELLO
message header will always be 0 and ignored by zebra.
- Zebra side:
- zserv_create_header() adds the VRF ID in the message header.
- zebra_client_read() extracts and validates the VRF ID from the
header, and passes the VRF ID to the functions which process
the received messages.
- All relative functions are appended with a new parameter "vrf_id".
* Suppress the messages in a VRF which a client does not care:
Some clients may not care about the information in the VRF X, and
zebra should not send the messages in the VRF X to those clients.
Extra flags are used to indicate which VRF is registered by a client,
and a new message ZEBRA_VRF_UNREGISTER is introduced to let a client
can unregister a VRF when it does not need any information in that
VRF.
A client sends any message other than ZEBRA_VRF_UNREGISTER in a VRF
will automatically register to that VRF.
- lib/vrf:
A new utility "VRF bit-map" is provided to manage the flags for
VRFs, one bit per VRF ID.
- Use vrf_bitmap_init()/vrf_bitmap_free() to initialize/free a
bit-map;
- Use vrf_bitmap_set()/vrf_bitmap_unset() to set/unset a flag
in the given bit-map, corresponding to the given VRF ID;
- Use vrf_bitmap_check() to test whether the flag, in the given
bit-map and for the given VRF ID, is set.
- Client side:
- In "struct zclient", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
default_information
These flags are extended for each VRF, and controlled by the
clients themselves (or with the help of zclient_redistribute()
and zclient_redistribute_default()).
- Zebra side:
- In "struct zserv", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
redist_default
ifinfo
ridinfo
These flags are extended for each VRF, as the VRF registration
flags. They are maintained on receiving a ZEBRA_XXX_ADD or
ZEBRA_XXX_DELETE message.
When sending an interface/address/route/router-id message in
a VRF to a client, if the corresponding VRF registration flag
is not set, this message will not be dropped by zebra.
- A new function zread_vrf_unregister() is introduced to process
the new command ZEBRA_VRF_UNREGISTER. All the VRF registration
flags are cleared for the requested VRF.
Those clients, who support only the default VRF, will never receive
a message in a non-default VRF, thanks to the filter in zebra.
* New callback for the event of successful connection to zebra:
- zclient_start() is splitted, keeping only the code of connecting
to zebra.
- Now zclient_init()=>zclient_connect()=>zclient_start() operations
are purely dealing with the connection to zbera.
- Once zebra is successfully connected, at the end of zclient_start(),
a new callback is used to inform the client about connection.
- Till now, in the callback of connect-to-zebra event, all clients
send messages to zebra to request the router-id/interface/routes
information in the default VRF.
Of corse in future the client can do anything it wants in this
callback. For example, it may send requests for both default VRF
and some non-default VRFs.

Later, an interface will belong to a specific VRF, and the interface
initialization will be a part of the VRF initialization. So now call
if_init() from vrf_init(), and if_terminate() from vrf_terminate().
Daemons have the according changes:
- if if_init() was called or "iflist" was initialized, now call
vrf_init() instead;
- if if_terminate() was called or "iflist" was destroyed, now call
vrf_terminate() instead.

The problem is that zclient->redist[ZEBRA_ROUTE_MAX] used for storing a
client’s redist state, has no address-family qualification. This means
a client can only store its interest in a protocol (connected, static etc.),
but cant choose IPv4 or ipv6 with that. This hindered implementation on
client sides to manage redistribution of ipv4 and ipv6 both.
BGP's redistribution of protocols like connected/static is one such place.
One fix could be to overload this and flap the redist connection each time
any new afi is added for redist, but that may have side-effects on the
existing afi redist.
The cleaner way is to modify redist data-structure to also take AFI, and adjust
routines that deal with it, so that a client can register for a protocol
redistribution based on the AFI. BGP already maintains redistribution state
based on afi and protocol (bgp->redist[AFI_MAX][ZEBRA_ROUTE_MAX]). This patch
takes care of filling up the gap in zclient/zserv redistribution state to
also use AFI qualification.

——————————————-------------
- etc/init.d/quagga is modified to support creating separate ospf daemon
process for each instance. Each individual instance is monitored by
watchquagga just like any protocol daemons.(requires initd-mi.patch).
- Vtysh is modified to able to connect to multiple daemons of the same
protocol (supported for OSPF only for now).
- ospfd is modified to remember the Instance-ID that its invoked with. For
the entire life of the process it caters to any command request that
matches that instance-ID (unless its a non instance specific command).
Routes/messages to zebra are tagged with instance-ID.
- zebra route/redistribute mechanisms are modified to work with
[protocol type + instance-id]
- bgpd now has ability to have multiple instance specific redistribution
for a protocol (OSPF only supported/tested for now).
- zlog ability to display instance-id besides the protocol/daemon name.
- Changes in other daemons are to because of the needed integration with
some of the modified APIs/routines. (Didn’t prefer replicating too many
separate instance specific APIs.)
- config/show/debug commands are modified to take instance-id argument
as appropriate.
Guidelines to start using multi-instance ospf
---------------------------------------------
The patch is backward compatible, i.e for any previous way of single ospf
deamon(router ospf <cr>) will continue to work as is, including all the
show commands etc.
To enable multiple instances, do the following:
1. service quagga stop
2. Modify /etc/quagga/daemons to add instance-ids of each desired
instance in the following format:
ospfd=“yes"
ospfd_instances="1,2,3"
assuming you want to enable 3 instances with those instance ids.
3. Create corresponding ospfd config files as ospfd-1.conf, ospfd-2.conf
and ospfd-3.conf.
4. service quagga start/restart
5. Verify that the deamons are started as expected. You should see
ospfd started with -n <instance-id> option.
ps –ef | grep quagga
With that /var/run/quagga/ should have ospfd-<instance-id>.pid and
ospfd-<instance-id>/vty to each instance.
6. vtysh to work with instances as you would with any other deamons.
7. Overall most quagga semantics are the same working with the instance
deamon, like it is for any other daemon.
NOTE:
To safeguard against errors leading to too many processes getting invoked,
a hard limit on number of instance-ids is in place, currently its 5.
Allowed instance-id range is <1-65535>
Once daemons are up, show running from vtysh should show the instance-id
of each daemon as 'router ospf <instance-id>’ (without needing explicit
configuration)
Instance-id can not be changed via vtysh, other router ospf configuration
is allowed as before.

Credit
------
A huge amount of credit for this patch goes to Piotr Chytla for
their 'route tags support' patch that was submitted to quagga-dev
in June 2007.
Documentation
-------------
All ipv4 and ipv6 static route commands now have a "tag" option
which allows the user to set a tag between 1 and 65535.
quagga(config)# ip route 1.1.1.1/32 10.1.1.1 tag ?
<1-65535> Tag value
quagga(config)# ip route 1.1.1.1/32 10.1.1.1 tag 40
quagga(config)#
quagga# show ip route 1.1.1.1/32
Routing entry for 1.1.1.1/32
Known via "static", distance 1, metric 0, tag 40, best
* 10.1.1.1, via swp1
quagga#
The route-map parser supports matching on tags and setting tags
!
route-map MATCH_TAG_18 permit 10
match tag 18
!
!
route-map SET_TAG_22 permit 10
set tag 22
!
BGP and OSPF support:
- matching on tags when redistribing routes from the RIB into BGP/OSPF.
- setting tags when redistribing routes from the RIB into BGP/OSPF.
BGP also supports setting a tag via a table-map, when installing BGP
routes into the RIB.

Quagga sources have inherited a slew of Page Feed (^L, \xC) characters
from ancient history. Among other things, these break patchwork's
XML-RPC API because \xC is not a valid character in XML documents.
Nuke them from high orbit.
Patches can be adapted simply by:
sed -e 's%^L%%' -i filename.patch
(you can type page feeds in some environments with Ctrl-V Ctrl-L)

The correct method to link to NetSNMP is to use net-snmp-config (which
is like pkg-config). Explicit link to libcrypto is also dropped
(NetSNMP libs are linked to libcrypto, no need to link Quagga to
it). Moreover, @SNMP_INCLUDES@ is dropped because useless. Due to a
bug in configure.ac, it was properly populated.

Some .h files in lib/ are autogenerated. The search path should
include the build directory and the source directory. They usually
match but sometimes, they may be different. For example:
$ mkdir build
$ cd build
$ ../configure
$ make

The previous commits modified both zebra and bgpd for additional
SAFI field, but not any other routing daemon, which led to zebra
daemon crashing with failed assertion.
