2015-11-05Initial commit on integrated BIRDOndrej Zajicek (work)
New data types net_addr and variants (in lib/net.h) describing network addresses (prefix/pxlen). Modifications of FIB structures to handle these data types and changing everything to use these data types instead of prefix/pxlen pairs where possible. The commit is WiP, some protocols are not yet updated (BGP, Kernel), and the code contains some temporary scaffolding. Comments are welcome.
2015-05-01OSPF: Redesign LSA checksummingOndrej Zajicek
New LSA checksumming code separates generic Fletcher-16 and OSPF-specific code and avoids back and forth endianity conversions, making it much more readable and also several times faster.
2015-04-28OSPF: Fixes validation of LSA checksumsOndrej Zajicek
Prior to this patch, BIRD validates the OSPF LSA checksum by calculating a new checksum and comparing it with the checksum in the header. Due to the specifics of the Fletcher checksum used in OSPF, this is not necessarily correct as the checkbytes in the header may be calculated via a different means and end up with a different value that is nonetheless still correct. The documented means of validating the checksum as specified in RFC 905 B.4 is to calculate c0 and c1 from the unchanged contents of the packet, which must result in a zero value to be considered valid. Thanks to Chris Boot for the patch.

2011-07-03Fixes LSA checksum computation for larger LSAs.Ondrej Zajicek
2011-03-17Vastly improved OSPF reconfiguration.Ondrej Zajicek
Now it can handle a change in iface pattern structure. It can add, remove and reconfigure interfaces, vlinks and areas.
2010-05-02Merge several fixes suggested by Joakim Tjernlund.Ondrej Zajicek
2010-05-02OSPF: most of summary LSA orig./flush logic rewritten.Ondrej Zajicek
Fixes many bugs in the old code and makes it much cleaner.
2010-04-25Skip LSA host<->network endianity conversions on big endians.Ondrej Zajicek
2010-04-24Fixes and enhancements in 'show ospf state' command.Ondrej Zajicek
Now it shows a distance, option to change showing reachable/all network nodes and better handling of AS-external LSAs in multiple areas. The command 'show ospf topology' was changed to not show stubnets in both OSPFv2 and OSPFv3 (previously it displayed stubnets in OSPFv2).
2010-02-21Fix configure to enable warnings and fix most of them.Ondrej Zajicek

2005-02-20Unused code deleted.Ondrej Filip
2004-07-15Huge OSPF database redesign. Since now, all LSAs of all areasOndrej Filip
are in single database. This avoids duplication of external LSAs and fixes bug in external LSA distribution.
2004-07-14Multiple OSPF areas can be attached.Ondrej Filip
Origination of summary LSA works. Routing table calculation works. Virtual links works. Well, I hope, OSPF is fully compatible with RFC2328!!!!
2004-07-13Don't inform us about every ospf_age()Ondrej Filip
2004-06-25A lot of changes:Ondrej Filip
- metric is 3 byte long now - summary lsa originating - more OSPF areas possible - virtual links - better E1/E2 routes handling - some bug fixes.. I have to do: - md5 auth (last mandatory item from rfc2328) - !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs) - 2328 appendig E
