.gitlab-ci.yml:
+ pkg targets for some distros added
+ artifacts added
- some distros were commented out (due to errors).
misc/docker/*:
+ Dockerfiles updated with the necessary packages.
init-system-helpers (>= 1.56~) can't be satisfied on:
* Ubuntu 18.04 (1.51)
* Ubuntu 16.04 (1.29)
* Debian 9 (1.48)
Remove the specific version requirement in order to enable build on
older platforms.
Adressing following FTBFS on all older debian/ubuntu distros:
Can't locate LinuxDocTools/Data/Latin1ToSgml.pm in @INC (you may need to install the LinuxDocTools::Data::Latin1ToSgml module)
Files in a single new distro/ dir allow apkg to build BIRD packages for
various distros directly from upstream sources as well as from upstream
archives.
Please see distro/README.md for more detail as well as apkg docs:
https://apkg.rtfd.io
I've used these files to build bird-2.0.8 on all currently supported
releases of following distros:
* Debian
* Ubuntu
* Fedora
* CentOS
* openSUSE
Please note that latest apkg with accumulated fixes for bird is needed:

For numeric operators, comma is used for disjunction in expressions like
"10, 20, 30..40". But for bitmask operators, comma is used for
conjunction in a way that does not really make much sense. Use always
explicit logical operators (&& and ||) to connect bitmask operators.
Thanks to Matt Corallo for the bugreport.
Add support to set or read outgoing MPLS labels using filters. Currently
this supports the addition of one label per route for the first next hop.
Minor changes by committer.
Implement function flow_explicate_part() to convert flowspec numeric
expressions to a simple list of (disjoint, sorted) intervals. That could
be used in filters to build f_tree-based int-sets from them.
The babel protocol code checks whether iface supports multicast, and
whether it has a link-local address assigned. However, it doesn not give
any feedback if any of those checks fail, it just silently ignores the
interface. Fix this by explicitly logging when multicast check fails.
Based on patch from Toke Høiland-Jørgensen, thanks!
The BSD code did not propagate the OS-level IFF_MULTICAST flag to the
Bird-internal IF_MULTICAST flag, which causes problems with Wireguard
interfaces on FreeBSD. The Linux sysdep code does propagate the flag
already, so just copy over the same check and flag update.
Ifaces with host address (/32) were forced to be stubby, but now they
can be used as PtP or PtMP. For these ifaces we need to:
- Do not force stub mode
- Accept packets from any IP as local
- Accept any configured neighbor as local
- Detect ifaces properly as unnumbered
- Use ONLINK flag for nexthops
As specified in RFC 2328 8.1: "On physical point-to-point networks,
the IP destination is always set to the address AllSPFRouters."
Note that this likely break setups with multiple neighbors on a network
configured as PtP, which worked before. These should be configured as
PtMP.
Thanks to Senthil Kumar Nagappan for the original patch and to Joakim
Tjernlund for suggestions.
BIRD uses hacked LinuxDocTools for building documentation, keeping some
parts locally and using remaining parts from system-installed one. This
setup breaks when LinuxDocTools makes some internal changes and is hard
to keep consistent.
Just include full LinuxDocTools code (both hacked and unmodified parts)
to avoid consistency issues. Note that we still need some binaries from
LinuxDocTools, so it still needs to be installed to build documentation.
For logging purposes a stack allocated net_addr struct was passed by
value as vararg (instead of the expected pointer). This resulted in
a segfault when the specific error condition got logged.
The code in tm_format_real_time() mixed up two buffers and their
sizes, which may cause crash in MRT dumping code.
Thanks to Piotr Wydrych for the bugreport.
The flag makes sense just in external representation. It is reset during
BGP export, but keeping it internally broke MRT dumps for short attributes
that used it anyways.
Thanks to Simon Marsh for the bugreport and the patch.
Debian 7 Wheezy has been superseded by Debian 8 Jessie on Apr 25, 2015,
with LTS support ending on May 31, 2018.
Debian 7 Wheezy's default GCC doesn't fully support C11. It should
anyway still be possible to build BIRD for Debian 7 if you backport
a C11-capable compiler there.
From now, there are no auxiliary pointers stored in the free slab nodes.
This led to strange debugging problems if use-after-free happened in
slab-allocated structures, especially if the structure's first member is
a next pointer.
This also reduces the memory needed by 1 pointer per allocated object.
OTOH, we now rely on pages being aligned to their size's multiple, which
is quite common anyway.
BGP statistics code was preliminary and i wanted to replace it by
separate 'show X stats' command. The patch hides the preliminary
output in 'show protocols all' so it is not part of the released
version.
In OSPFv3, only Hello and DBDes packets contain flags specifying whether
RFC 7166 authentication trailer is used. Other packets are processed
based on stored authentication state in neighbor structure. Update this
state with each received Hello to handle authentication change from
reconfigurations.
Thanks to Joakim Tjernlund and Kenth Eriksson for the bugreport.
In general, events are code handling some some condition, which is
scheduled when such condition happened and executed independently from
I/O loop. Work-events are a subgroup of events that are scheduled
repeatedly until some (often significant) work is done (e.g. feeding
routes to protocol). All scheduled events are executed during each
I/O loop iteration.
Separate work-events from regular events to a separate queue and
rate limit their execution to a fixed number per I/O loop iteration.
That should prevent excess latency when many work-events are
scheduled at one time (e.g. simultaneous reload of many BGP sessions).
