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.

Thanks to Igor Podlesny for notification.

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.

Most protocols in IPv6 mode use link-local source addresses and expect
that there is one on each active interface. The old code depended on
assumption that if there is some IPv6 address on iface, there is also an
IPv6 link-local address on that iface (added by kernel when the iface
went up). Unfortunately, that is not generally true, as a configured
global address sometimes ceases to be tentative (finishes DOD) before
a link-local address on the same iface. In such case a protocol iface
(namely RAdv and Babel) is activated, but fails to found link-local
address and stays in failed state.
The patch fixes that by tracking 'primary' IPv6 link-local address,
sending iface restart notifications when it changes and making
protocols ignore iface-up notifications when no such address is
selected for an iface.

Allow to change an interface associated with a route by setting
ifname attribute. It will also change the route to a direct one.

Missing argument in MTU change trace message can crash bird when MTU
change happens and trace messages are active.
Thanks to Alexander Velkov for the bugreport.

The new MRT protocol is responsible for periodic RIB table dumps in the
MRT format (RFC 6396). Also the existing code for BGP4MP MRT dumps is
refactored and splitted between BGP to MRT protocols, will be more
integrated into MRT in the future.
Example:
protocol mrt {
table "*";
filename "%N_%F_%T.mrt";
period 60;
}
It is partially based on the old MRT code from Pavel Tvrdik.
|
|
|
|
The old code does not cause GR if BFD failed when GR is running,
session is re-established but not yet synchronized.

BSD systems cannot use SO_DONTROUTE, because it does not work properly
with multicast packets (perhaps it tries to find iface based on multicast
group address). But we can use MSG_DONTROUTE sendmsg() flag for unicast
packets. Works on FreeBSD, is ignored on OpenBSD and is broken on NetBSD
(i guess due to integrated routing table and ARP table).

Backport of commit 09c1e370b3084f7acb7c3777427670a69945368a.
|

When use of LLGR is negotiated, handle hold timeout by LLGR instead of by
hard restart. Allow to configure whether BFD session down event should be
handled by GR/LLGR or by hard restart.

The patch implements long-lived graceful restart for BGP, namely
draft-uttaro-idr-bgp-persistence-03.

If export filter is changed during reconfiguration and a route disappears
between reconfiguration and refeed (e.g., if the route is a static route
also removed during the reconfiguration), the route is not withdrawn.
The issue was fixed for regular channels by an earlier patch. This patch
fixes the issue for channels in RA_ACCEPTED mode (first-pass-the-filter),
used by BGP with 'secondary' option.
|
|
If export filter is changed during reconfiguration and a route disappears
between reconfiguration and refeed (e.g., if the route is a static route
also removed during the reconfiguration), the route is not withdrawn.
The patch fixes that by adding tx reconfiguration timestamp.
