2018-07-01BGP: Use implicit-NULL label when announcing MPLS routes with local next-hopOndrej Zajicek (work)
We currently cannot assing local labels, but we can still be LSP egress router. Therefore when we announce labeled route with local next-hop, we should announce implicit-NULL label instead of rejecting it completely.
2018-07-01BGP: Fix parsing of MPLS withdrawalsOndrej Zajicek (work)
RFC 3107 was bit vague with regard to labeled withdrawals, RFC 8277 clarified that. The old code was incompatible with some implementations, namely with Juniper. Thanks to Vadim Fedorenko for the original patch.
2018-06-27Nest: Neighbor cache cleanupsOndrej Zajicek (work)
Simplify neighbor cache code, fix several minor bugs, and improve handling of ONLINK flag.
2018-01-23Merge branch 'master' into int-newOndrej Zajicek (work)
2018-01-16BGP: Implement 'disable after cease' optionOndrej Zajicek (work)
The option allows to specify that some cease subcodes should disable the protocol when received.
2018-01-02BGP: Fix unknown attribute handlingOndrej Zajicek (work)

2017-12-08BGP: Fix IPv6 MPLS/VPN multicast SAFIOndrej Zajicek (work)
2017-12-07Merge commit '1e8721e2aeccfbc3f533e8b8abc07582cee77e9a' into int-newOndrej Zajicek (work)
2017-09-19BGP: Shutdown communication (RFC 8203)Ondrej Zajicek (work)
The patch implements BGP Administrative Shutdown Communication (RFC 8203) allowing BGP operators to pass messages related to BGP session administrative shutdown/restart. It handles both transmit and receive of shutdown messages. Messages are logged and may be displayed by show protocol all command. Thanks to Job Snijders for the basic patch.
2017-04-12BGP: Add support for SAFI 129 (VPN multicast)Ondrej Zajicek (work)
Which, in contrast to SAFI 128, does not use MPLS labels.
2017-03-29BGP: Update list of supported standardsOndrej Zajicek (work)
2017-03-26BGP: Support for routes with mixed-AF next hopsOndrej Zajicek (work)
Covers IPv4/VPNv4 routes with IPv6 next hop (RFC 5549), IPv6 routes with IPv4 next hop (RFC 4798) and VPNv6 routes with IPv4 next hop (RFC 4659). Unfortunately it also makes next hop hooks more messy. Each BGP channel now could have two IGP tables, one for IPv4 next hops, the other for IPv6 next hops.
2017-03-23BGP: Bugfix in VPN NLRI encodingOndrej Zajicek (work)
2017-03-22BGP: Support for MPLS labels and VPN SAFIOndrej Zajicek (work)
Basic support for SAFI 4 and 128 (MPLS labeled IP and VPN) for IPv4 and IPv6. Should work for route reflector, but does not properly handle originating routes with next hop self. Based on patches from Jan Matejka.
2017-03-17Nexthop: Fixed recursive route mpls label mergingJan Moskyto Matejka
2017-03-14BGP: Fix bug in ADD_PATHOndrej Zajicek (work)
When a BGP session with ADD_PATH is restarted and the neighbor do not announce ADD_PATH capability during reconnect, the accept_ra_types is still set to RA_ANY. Thanks to Lennert Buytenhek for the bugreport

2017-01-24BGP: Partial support for IPv4 routes with IPv6 next hop (RFC 5549)Ondrej Zajicek (work)
Mostly capability signalling
2017-01-03Minor cleanupsOndrej Zajicek (work)
2016-12-22Removing (struct rta)->cast. Never used.Jan Moskyto Matejka
2016-12-22Merged multipath and single-path data structures.Jan Moskyto Matejka
Dropped struct mpnh and mpnh_*() Now struct nexthop exists, nexthop_*(), and also included struct nexthop into struct rta. Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed to distinguish between these two cases, RTD_DEVICE is equivalent to IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw). From now on, we also explicitely want C99 compatible compiler. We assume that this 20-year norm should be known almost everywhere.
2016-12-20BGP: Report capabilities in show protocols allOndrej Zajicek (work)
2016-12-07BGP: Add support for flowspec (RFC 5575)Ondrej Zajicek (work)
2016-12-07BGP redesignOndrej Zajicek (work)
Integrated and extensible BGP with generalized AFI handling, support for IPv4+IPv6 AFI and unicast+multicast SAFI.
2016-11-01Build: switch on -Wextra, get rid of most of the warningsJan Moskyto Matejka
There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.
2016-07-11BGP: Fix extended messagesOndrej Zajicek (work)
Change attribute length limit to handle extended (64 kB) messages. Do not mix updates and withdraws (RFC 7606).
2015-11-25BGP: Update capability number from IANA for extended messagesOndrej Zajicek (work)
2015-07-18BGP: Extended messages supportOndrej Zajicek
Implements draft-ietf-idr-bgp-extended-messages-10, for now undocumented and with temporary private capability number.

2015-04-01BGP: 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.
2014-10-24Integrated IP functions.Ondrej Zajicek
2014-10-02Implements token bucket filter for rate limiting.Ondrej Zajicek
2014-05-04Fixes BGP crash when update with some attributes and empty NLRI is received.Ondrej Zajicek
Thanks to Charlie Allom for the bugreport.
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.
2014-03-24Fixes a bug in graceful restart.Ondrej Zajicek
2014-03-20BGP graceful restart support.Ondrej Zajicek
Also significant core protocol state changes needed for that, global graceful restart recovery state and kernel proto support for recovery.
2013-12-01Finishes add-path.Ondrej Zajicek
Fixes some bugs and uses generic hash implementation.

2013-04-29Fixes a crash when mrtdump is enabled and interface goes away.Ondrej Zajicek
Thanks to Peter Christensen for the bugfix.
2013-04-16Fixes a bug in IPv6 BGP next hop processing.Ondrej Zajicek
BGP next hop attributes with empty link-local IPv6 addresses were not handled properly. Thanks to Sergey Popovich for the bugfix.
2012-08-14Implements ADD-PATH extension for BGP.Ondrej Zajicek
Allows to send and receive multiple routes for one network by one BGP session. Also contains necessary core changes to support this (routing tables accepting several routes for one network from one protocol). It needs some more cleanup before merging to the master branch.
