Implemented as per the feature description given in the source link.
Descriprion:
The BGP conditional advertisement feature uses the non-exist-map or exist-map
and the advertise-map keywords of the neighbor advertise-map command in order
to track routes by the route prefix.
non-exist-map :
If a route prefix is not present in output of the non-exist-map command, then
the route specified by the advertise-map command is announced.
exist-map :
If a route prefix is present in output of the exist-map command, then the route
specified by the advertise-map command is announced.
The conditional BGP announcements are sent in addition to the normal
announcements that a BGP router sends to its peers.
The conditional advertisement process is triggered by the BGP scanner process,
which runs every 60 seconds. This means that the maximum time for the conditional
advertisement to take effect is 60 seconds. The conditional advertisement can take
effect sooner, depending on when the tracked route is removed from the BGP table
and when the next instance of the BGP scanner occurs.

There are several places where prefix2str was used to convert
a prefix but they were debug guarded and the buffer was
used for flog_err/warn. This would lead to corrupt data
being output in the failure cases if debugs were not turned
on.

Problem found that turning an update-delay would only delay prefixes
learned from peers by delaying bestpath, but would allow local routes
(network statements or redistributed) to be immediately advertised,
followed by an End of Rib indicator. This fix delays sending local
routes until the update-delay process is completed, which matches
what testing shows other vendors do..

Make it possible to load YANG modules outside the main northbound
initialization. The primary use case is to support YANG modules
that are specific to an FRR plugin. Example: only load the PCEP
YANG module when the corresponding FRR plugin is loaded. Other use
cases might arise in the future.

Combine yang_snodes_iterate_module() and yang_snodes_iterate_all()
into an unified yang_snodes_iterate() function, where the first
"module" parameter is optional. There's no point in having two
separate YANG schema iteration functions anymore now that they are
too similar.
Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
|

The only safe way to iterate over all schema nodes of a given YANG
module is by iterating over all schema nodes of all YANG modules
and filter out the nodes that belong to other modules.
The original yang_snodes_iterate_module() code did the following:
1 - Iterate over all top-level schema nodes of the given module;
2 - Iterate over all augmentations of the given module.
While that iteration strategy is more efficient, it does't handle
well more complex YANG hierarchies containing nested augmentations
or self-augmenting modules. Any iteration that isn't done on the
resolved YANG data hierarchy is fragile and prone to errors.
Fixes regression introduced by commit 8a923b48513316b where the
gen_northbound_callbacks tool was generating duplicate callbacks
for certain modules.

Previous commits added LTTng tracepoints. This was primarily for testing
/ trial purposes; in practice we'd like to support arbitrary tracing
methods, and especially USDT probes, which SystemTap and dtrace expect,
and which are supported on at least one flavor of BSD (FreeBSD).
To that end this patch adds an frr-specific tracing macro, frrtrace(),
which proxies into either DTRACE_PROBEn() or tracepoint() macros
depending on whether --enable-usdt or --enable-lttng is passed at
compile time.
At some point this could be tweaked to allow compiling in both types of
probes. Ideally there should be some logic there to use LTTng's optional
support for generating USDT probes when both are requested.
No additional libraries are required to use USDT, since these probes are
a kernel feature and only need the <sys/sdt.h> header.
- add --enable-usdt to toggle use of LTTng tracepoints or USDT probes
- add new trace.h library header for use with tracepoint definition
headers
- add frrtrace() wrapper macro; this should be used to define
tracepoints instead of using tracepoint() or DTRACE_PROBEn()
Compilation with USDT does nothing as of this commit; the existing LTTng
tracepoints need to be converted to use the frrtrace*() macros in a
subsequent commit.

LTTng supports tracef() and tracelog() macros, which work like printf,
and are used to ease transition between logging and tracing. Messages
printed using these macros end up as trace events. For our uses we are
not interested in dropping logging, but it is nice to get log messages
in trace output, so I've added a call to tracelog() in zlog that dumps
our zlog messages as trace events.

Add the following Anycast-SIDs on routers rt4 and rt5:
* segment-routing prefix 10.10.10.10/32 index 100 no-php-flag n-flag-clear
* segment-routing prefix 2001:db8:1000::10/128 index 101 no-php-flag n-flag-clear
The updated JSON data will then check whether the Anycast-SIDs are
being processed as expected (e.g. rt1 should use ECMP to rt2 and rt3,
rt2 should use rt4 only as it's directly connected, etc).

Add the "n-flag-clear" option to the "segment-routing prefix"
command. The only thing that option does is to clear the node
flag of the Prefix-SID, even if it corresponds to a local loopback
address. No changes are necessary other than that in order to fully
support Anycast-SIDs. isisd already supports multiple routers
advertising the same route with the same Prefix-SID after the recent
refactoring. Clearing the node flag for such anycast routes isn't
strictly required, but failure to do so can lead to problems like
TI-LFA picking the wrong Prefix-SID when calculating repair paths.

When computing backup nexthops for routes that contain a Prefix-SID,
the original Prefix-SID label should be present at the end of
backup label stacks (after the repair labels). This commit fixes
that oversight in the original TI-LFA code. The SPF unit tests and
TI-LFA topotes were also updated accordingly.

Embed Prefix-SID information inside SPF data structures so that
Prefix-SIDs can be installed together with their associated routes
at the end of the SPF algorithm. This is different from the current
implementation where Prefix-SIDs are parsed and processed separately,
which is vastly suboptimal.
Advantages of the new code:
* No need to parse the LSPDB an additional time to detect and process
SR-related changes;
* Routes are installed with their Prefix-SID labels in the same ZAPI
message. This can prevent packet dropping for a few milliseconds
after each SPF run if there are BGP-labeled routes (e.g. L3VPN) that
recurse on IGP labeled routes;
* Much easier to support Anycast-SIDs, as the SPF code will naturally
figure out the best nexthops and use only them (that can't be done
in any reasonable way if the Prefix-SID Sub-TVLs are processed
separately);
* Less code to maintain and reduced memory footprint;
The "show isis segment-routing prefix-sids" command was removed as
it doesn't make sense anymore now that "show isis route" exists.
Prefix-SIDs are a property of routes, so what was done was to extend
the "show isis route" command with a new "prefix-sid" option that
changes the output table to show the Prefix-SID information associated
to each route.

This is preparatory change for the upcoming SR Prefix-SID
refactoring.
Since Prefix-SID information will be stored inside IS-IS routes
(instead of being maintained separately), it will be necessary to
have local routes in order to store local Prefix-SID information.

When both old and new-style TLVs exist for a particular prefix, give
precedence to the new-style TLV (like JUNOS does) when generating
routes from the SPT. This changes the current behavior which is to
generate a route for both TLVs, whereas the first is overwritten by
the second in a non-deterministic order (i.e. either the old-style
or the new-style TLV can "win" depending on how the SPF TENTative
list is arranged).

Because the backup nexthop groups currently are more like pseudo-NHEs
(they don't have IDs and are not inserted into the ID table or
hashed), they can't really have this depends/dependents relationship
yet in both directions. Some work needs to be done there to make
them more like first class citizens like "normal" NHGs to enable
this.
