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.

2014-02-06Many changes in I/O and OSPF sockets and packet handling.Ondrej Zajicek
I/O: - BSD: specify src addr on IP sockets by IP_HDRINCL - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO - Alternative SKF_BIND flag for binding to IP address - Allows IP/UDP sockets without tx_hook, on these sockets a packet is discarded when TX queue is full - Use consistently SOL_ for socket layer values. OSPF: - Packet src addr is always explicitly set - Support for secondary addresses in BSD - Dynamic RX/TX buffers - Fixes some minor buffer overruns - Interface option 'tx length' - Names for vlink pseudoifaces (vlinkX) - Vlinks use separate socket for TX - Vlinks do not use fixed associated iface - Fixes TTL for direct unicast packets - Fixes DONTROUTE for OSPF sockets - Use ifa->ifname instead of ifa->iface->name

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!!!!
2004-06-26Md5 authentification added (unsested).Ondrej Filip
Packet receiving clean up.
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
