31e9e10144 netlink: update struct msghdr
The netlink code assumes an order for the members of struct msghdr.
This breaks recvmsg and sendmsg with musl libc on mips64. Fix this by
using designated initializers instead.

937e75d8f1 Add the Babel routing protocol (RFC 6126)

06edbb67ed Nest: Reset export route counter during graceful restart
Counter exp_routes is increased during initial route feed after GR
recovery, so it has to start with zero, otherwise BIRD will end with
double value in exp_routes.

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.

54bb032d21 Birdlib: Modify lists to avoid problems with pointer aliasing rules
The old linked list implementation used some wild typecasts and required
GCC option -fno-strict-aliasing to work properly. This patch fixes that.
However, we still keep the option due to other potential problems.

39a6b19d6d OSPF: Fix bogus LSA ID collisions between received and originated LSAs
After restart, LSAs locally originated by the previous instance are
received from neighbors. They are installed to LSA db and flushed. If
export of a route triggers origination of a new external LSA before flush
of the received one is complete, the check in ospf_originate_lsa() causes
origination to fail (because en->nf is NULL for the old LSA and non-NULL
for the new LSA). The patch fixes this by updating the en->nf for LSAs
being flushed (as is already done for empty ones). Generally, en->nf
field deserves some better description in the code.

Thanks to Jigar Mehta for analyzing the problem.

487c6961cb BGP: Fix bug in incoming connection handling
When a BGP session was established by an outgoing connection with
Graceful Restart behavior negotiated, a pending incoming connection in
OpenSent state, and another incoming connection was received, then the
outgoing connection (and whole BGP session) was closed, but the old
incoming connection was just overwritten by the new one. That later
caused a crash when the hold timer from the old connection fired.
