We forgot to do that. Oops.

The attribute should not be modifiable by filters as we do not
support its type.

There is an improper check for valid message size, which may lead to
stack overflow and buffer leaks to log when a large message is received.
Thanks to Daniel McCarney for bugreport and analysis.

Protocol can have specified VRF, in such case it is restricted to a set
of ifaces associated with the VRF, otherwise it can use all interfaces.
The patch allows to specify VRF as 'default', in which case it is
restricted to a set of iface not associated with any VRF.

This led in corner cases to undefined buffer content
and garbage output.

Mismatched types to printf(). The old code coincidentally worked on amd64
due to its calling conventions.
Thanks to Maximilian Eschenbacher for the bugreport.

Allow multiple BFD instances in separate VRFs, dispatch BFD requests
according to VRFs.
Thanks to Alexander Zubkov for notice and patches.

When priority is reconfigured locally, we need to trigger DR election.

This doesn't make any change for you until you have
millions of updates waiting to be sent. Increasing
the max hash size from 2^20 to 2^24.

If BGP has too many data to send and BIRD is slower than the link, TX is
always possible until all data is sent. This patch limits maximum number
of generated BGP messages in one iteration of TX hook.

Route flags are mosty internal state of rtable, they are not significant
to whether a route has changed. With the old code, all routes received as
a part of enhanced route refresh are always re-announced to other peers
due to change in REF_STALE.

accepted mode)
Update for one of previous patches, handles the the issue for
first-accepted mode of route propagation.
|
|
One of previous workarounds for phantom route avoidance breaks export
counters by expanding sending of spurious withdraws, which are send when
we are not sure whether we have advertised that routes in the past.
If not, then export counter is decreased, but it was not increased
before, so it overflows under zero.
The patch fixes that by sending spurious withdraws, but not counting them
on export counter. That may lead to error in the other direction, but
that happens only as a race condition (i.e., in normal operation filters
return proper values about old route export state).
|

The earlier fix loosen conditions for not running filters on old
route when deciding about route propagation to a protocol to avoid
issues with ghost routes in some race conditions.
Unfortunately, the fix also caused back-propagation of withdraws. For
regular updates, back-propagation is prevented in import_control hooks,
but these are not called on withdraws. For them, import_control hooks
are called on old routes instead, changing (old, NULL) notification
to (NULL, NULL), which is ignored. By not calling export processing
in some cases, the withdraw is not ignored and is back-propagated.
This patch fixes that by contract conditions so the earlier fix is not
applied to back-propagated updates.

One of previous commits bacported from 2.0 removed suffix from bird.ctl

Current FreeBSD kernels require SA records for both directions.
Thanks to Joseph Mulloy and Andrey V. Elsukov for reporting and
solving the issue.

Minor cleanups, updates and clarifications. Also removes (incomplete
and well-known) build steps from README, as they are better described
in INSTALL.

The existing paths are valid for Debian, alternative paths are necessary
for Fedora and RHEL/CentOS.

Newer Autoconf defines --runstatedir option for setting directory for
run-time variable data. Use it instead our old --with-runtimedir.

Some new route source values did not have associated string
in rta_show(), which might caused crash in some cases.

Fixes type issue when u64 is pushed into it.

Not relevant for regular BGP paths, just for BGP paths added by filters
to e.g. static routes.

The command showed interfaces that were removed / in shutdown.

Thanks to Clemens Schrimpe for the bugreport.

FreeBSD silently changes TTL to 1 when MSG_DONTROUTE is used, even when
it is explicitly set to another value. That breaks TTL security sockets,
including BFD which always uses TTL 255. Bad FreeBSD!

It reduces clutter in root and also avoid collision with doc dir on
case-insensitive filesystems when name back to Doc.
|

|
|
In some circumstances (old LSA flushed but not acknowledged and not
removed) origination of a new LSA may wrongly triggers LSA collision
code. The patch fixes that.
Thanks to Asbjorn Mikkelsen for the bugreport and @mdelagueronniere
for the original patch.

Fix crash during reconfiguration of OSPF config with vlinks. When vlink
is reconfigured, a generic iface-reconfiguration code is used, which in
one place supposes that it is running on a regular iface.
Thanks to Cybertinus for a bugreport.

Neighbor entries for static ECMP routes were not cleaned up during
reconfigure and pointed to the old instances, which leads to crash
after reconfigure.
Thanks to Vladimir Osmolovskiy for the bugreport.
