2016-05-12Prog Doc: Complete several missing parametersPavel Tvrdik
2016-04-28Add the Babel routing protocol (RFC 6126)Ondrej Zajicek (work)
This patch implements the IPv6 subset of the Babel routing protocol. Based on the patch from Toke Hoiland-Jorgensen, with some heavy modifications and bugfixes. Thanks to Toke Hoiland-Jorgensen for the original patch.
2016-04-13BSD: Add the IPsec SA/SP database entries controlOndrej Zajicek (work)
Add code for manipulation with TCP-MD5 keys in the IPsec SA/SP database at FreeBSD systems. Now, BGP MD5 authentication (RFC 2385) keys are handled automatically on both Linux and FreeBSD. Based on patches from Pavel Tvrdik.
2016-04-06IO: Avoid multiple event cycles in one loop cycle.Ondrej Zajicek (work)
Event cycle may took too much time and trigger next timer events, so avoid cycling between timer and event cycles inside the loop cycle.
2016-04-06IO: Replace RX priority heuristic with explicit markOndrej Zajicek (work)
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.
2016-03-23Birdlib: Do cleanups after remove/freeOndrej Zajicek (work)
To avoid byzantine behavior in case of some errors, linked lists are cleared after rem_node() and resource headers are cleared after rfree().
2016-03-23OSPF: Fix bogus LSA ID collisions between received and originated LSAsOndrej Zajicek (work)
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.
2016-03-23OSPF: Fix reading from freed memoryOndrej Zajicek (work)
Thanks to Pavel Tvrdik for noticing it.

2016-02-25OSPF: Multicast ability is irrelevant for stub interfacesOndrej Zajicek (work)
2016-02-11BGP: Fix bug in incoming connection handlingOndrej Zajicek (work)
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.
2015-11-25BGP: Update capability number from IANA for extended messagesOndrej Zajicek (work)
2015-11-24MD5: Mormalize naming stylePavel Tvrdík
2015-10-17Merge branch 'master' into rip-newOndrej Zajicek (work)
2015-10-05Major RIP redesignOndrej Zajicek (work)
The new RIP implementation fixes plenty of old bugs and also adds support for many new features: ECMP support, link state support, BFD support, configurable split horizon and more. Most options are now per-interface.
2015-08-19OSPF: Fixes some issues with link detectionOndrej Zajicek
Thanks to Bernardo Figueiredo and Israel G. Lugo for the bugreport.
2015-07-24Static: Support for BFD controlled static routesOndrej Zajicek
2015-07-20Static: Allows to specify attributes for static routesOndrej Zajicek
The patch adds suport for specifying route attributes together with static routes, e.g.: route 10.1.1.0/24 via 10.0.0.1 { krt_advmss = 1200; ospf_metric1 = 100; };
2015-07-19BFD: Fixes crash after socket errorOndrej Zajicek
Thanks to Thomas King for the bugreport.
2015-07-18BGP: Extended messages supportOndrej Zajicek
Implements draft-ietf-idr-bgp-extended-messages-10, for now undocumented and with temporary private capability number.
2015-06-08BGP multipath supportOndrej Zajicek
Kernel option 'merge paths' allows to merge routes exported to kernel protocol (currently BGP and static routes) to multipath routes.

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.
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.
2015-04-12Minor fixesOndrej Zajicek
2015-04-01BGP: Fixes serious bug in TX handlingOndrej Zajicek
Under some circumstances and heavy load, TX could be postponed until the session fails with hold timer expired. Thanks to Javor Kliachev for making the bug reproductible.
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
Temporary rta is reused in BGP, while rta_lookup() breaks it. Thanks to Alexander Chernikov for analysing the problem.

2015-02-22Rename BGP option 'start delay' to 'connect delay'Ondrej Zajicek
Also update log message for error-triggered startup delay.
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.
