Hmm, #ifdef is not very typo-safe.

f9bdcad469 Fixes type mismatch in OSPF printf statements.
Mixing ip_addr and u32 does bad things on Ultrasparc.
Although both have the same size. Fascinating.
It was not catched by compiler because of varargs.

29c430f856 Changes handling of AS_PATH_CONFED_* segments in AS_PATH.
Although standard says that if we receive AS_PATH_CONFED_*
(and we are not a part of a confederation) segment, we should
drop session, nobody does that and it is unwise to do that.

Now we drop session just in case that peer ASN is in
AS_PATH_CONFED_* segment (to detect peer that considers BIRD
as a part of its confederation).

f571473ef3 Hello packets on PTP networks should have zero netmask.
This also ensures that misconfigured routers (one side
ptp and one side broadcast) do not make adjacency.

20e94fb85b A change in OSPF and RIP interface patterns.
Allows to add more interface patterns to one common 'options'
section like:

interface "eth3", "eth4" { options common to eth3 and eth4 };

Also removes undocumented and unnecessary ability to specify
more interface patterns with different 'options' sections:

interface "eth3" { options ... }, "eth4" { options ... };

024c310b53 Fixes broken cryptographic authentication in OSPF
Cryptographic authentication in OSPF is defective by
design - there might be several packets independently
sent to the network (for example HELLO, LSUPD and LSACK)
where they might be reordered and that causes crypt.
sequence number error.

That can be workarounded by not incresing sequence number
too often. Now we update it only when last packet was sent
before at least one second. This can constitute a risk of
replay attacks, but RFC supposes something similar (like time
in seconds used as CSN).

b722fe7ebd Fixes bug in OSPF packet retransmission.
If a DBDES packet from a master to a slave is lost, then the old code
does not retransmit it and instead send a next one with the same
sequence number. That leads to silent desynchronization of LSA
databases.

8298d780be Better OSPF packet tracing log messages.

48d79d521c Better handling of AS4 optional attribute errors
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
 - ignoring invalid AS4 optional attributes.

82a79586e5 Better handling of too long attributes
This patch extends the length for attributes from 1024 to 2048
(because both AS_PATH and AS4_PATH attributes take 2+4 B per AS).

If there is not enough space for attributes, Bird skips that
route group. Old behavior (skipping remaining attributes)
leads to skipping required attributes and session drop.

a9dc5e1ef2 Fixes another bug in packet retransmissions.
When slave was in full state, it didn't retransmit
lost packets. That leads to OSPF connection locked
