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.
2015-04-18OSPF: Fixes handling of external routes with immediate gwOndrej Zajicek
The bug caused that received external LSAs with locally reachable next hops were ignored. I wonder why nobody noticed it sooner.

2015-04-01BGP: Fixes serious bug in TX handlingOndrej Zajicek

2015-03-29BGP: AS-wide unique router ID (RFC 6286) supportOndrej Zajicek
RFC 6286 relaxed rules for router IDs, allowing EBGP sessions between routers with the same ID (but different ASN).
2015-03-29BGP: Enhanced route refresh (RFC 7313) supportOndrej Zajicek
Also hook feed_done is renamed to feed_end.
2015-03-02Fixes serious bug in BGP add-pathOndrej Zajicek

2015-02-22Use IP_PORTRANGE_HIGH for BFD where availableOndrej Zajicek
2015-02-22Rename BGP option 'start delay' to 'connect delay'Ondrej Zajicek

2015-02-22Relax BGP neighbor parameterOndrej Zajicek
Permit specifying neighbor address, AS number and port independently. Add 'interface' parameter for specifying interface for link-local sessions independently. Thanks to Alexander V. Chernikov for the original patch.
2015-02-21Store protocol config size inside protocol structureOndrej Zajicek
Make proto_config_new() use this info instead of supplied size. Thanks to Alexander V. Chernikov for the patch.

2014-04-14Fixes a bug in (mainly) IPv6 BGP.Ondrej Zajicek
Stack variable may be used unitialized and that would lead to spurious rta_free(), which may cause crash. The bug was introduced in 1.4.1 from merging add-path branch. Thanks to Peter Andreev for reporting it and Alexander V. Chernikov for resolving it.

2014-04-02Fixes nasty bug in BFD.Ondrej Zajicek
When a BFD session is removed while being scheduled for notification, the session stays in notify list and is removed twice, which leads to a strange crash after a while.

2014-02-06Silence this annoying warning.Ondrej Zajicek
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
