3e236955c9 Build: switch on -Wextra, get rid of most of the warnings
There are several unresolved -Wmissing-field-initializers on older

17fe57d8dc Log: Fix broken syslog name
BIRD passed string from configuration to openlog(), which kept it
internally. After reconfiguration the old string was freed, therefore
openlog had invalid copy.

Thanks to Chris Caputo for the original patch.

a290da25a1 rt-table: Fix kernel protocol export filter memory bug
Kernel protocol calls rt_export_merged(), which used @rte_update_pool for
temporary allocations, supposing it is called from other functions from
rt-table.c that handles locking and flushing of the linpool. Therefore,
linpool was not flushed properly and memory leaked.

Add linpool argument to rt_export_merged() and use @krt_filter_lp when
called from kernel protocol.

Thanks to Justin Cattle and Alexander Frolkin for the bugreport.

f9f2e280ea KRT: Forbid path merging on BSD
We support ECMP routes only on Linux. Exported routes are checked in
krt_capable(), but a route generated during path merging avoids this
check.

7152e5efbb Build system reworked to one global Makefile with includes and no nesting
Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.

Fixed make doc on recent Debian together with moving generated doc into
objdir.

Moved Makefile.in into root dir

Retired all.o and birdlib.a
Linking the final binaries directly from all the .o files.

a7baa09862 BSD: Add the IPsec SA/SP database entries control
Add code for manipulation with TCP-MD5 keys in the IPsec SA/SP database
at FreeBSD systems. Now, BGP MD5 authentication (RFC 2385) keys are
handled automatically on both Linux and FreeBSD.

Based on patches from Pavel Tvrdik.

2003a18407 Route update: move table lookup from protocols into rte_update2().
Many protocols do almost the same when creating a rte_update request
before calling rte_update2(). This commit should simplify the protocol
side of the route-creation routine.

bd22d7f41d IO: Avoid multiple event cycles in one loop cycle.
Event cycle may took too much time and trigger next timer events, so
avoid cycling between timer and event cycles inside the loop cycle.

9e7b3ebdf9 IO: Replace RX priority heuristic with explicit mark
In BIRD, RX has lower priority than TX with the exception of RX from
control socket. The patch replaces heuristic based on socket type with
explicit mark and uses it for both control socket and BGP session waiting
to be established.

This should avoid an issue when during heavy load, outgoing connection
could connect (TX event), send open, but then failed to receive OPEN /
establish in time, not sending notifications between and therefore
got hold timer expired error from the neighbor immediately after it
finally established the connection.

e86cfd41d9 KRT: Fix route learn scan when route changed
When a kernel route changed, function krt_learn_scan() noticed that and
replaced the route in internal kernel FIB, but after that, function
krt_learn_prune() failed to propagate the new route to the nest, because
it confused the new route with the (removed) old best route and decided
that the best route did not changed.

Wow, the original code (and the bug) is almost 17 years old.
