2017-04-28Merge master into int-newOndrej 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.
2017-02-23BGP: Allow exchanging LOCAL_PREF with eBGP peersOndrej Zajicek (work)
Adds option 'allow bgp_local_pref' to override the usual restriction of LOCAL_PREF on eBGP sessions. Thanks to Lennert Buytenhek for the patch.

2017-02-07BGP: Minor cleanupsOndrej Zajicek (work)
2017-01-24BGP: Partial support for IPv4 routes with IPv6 next hop (RFC 5549)Ondrej Zajicek (work)
Mostly capability signalling
2017-01-22BGP: Support for AS confederations (RFC 5065)Ondrej Zajicek (work)
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.
2016-12-07BGP: 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.
2016-11-25BGP: Fix memory leak in graceful restart codeOndrej Zajicek (work)
Prefix and bucket tables are initialized when entering established state but not explicitly freed when leaving it (that is handled by protocol restart). With graceful restart, BGP may enter and leave established state multiple times without hard protocol restart causing memory leak.
2016-11-15BGP: Cluster list item should be prependedOndrej Zajicek (work)
Commit 3c09af41... changed behavior of int_set_add() from prepend to append, which makes more sense for community list, but prepend must be used for cluster list. Add int_set_prepend() and use it in cluster list handling code.
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.
2016-10-03BGP: Support for large communitiesOndrej Zajicek (work)
Add support for large communities (draft-ietf-idr-large-community), 96bit alternative to RFC 1997 communities. Thanks to Matt Griswold for the original patch.
2016-06-29BGP: Skip empty path segments in received AS_PATHOndrej Zajicek (work)
Although RFC 4271 does not forbid empty path segments, they are useless and some implementations consider them invalid. It is clarified in RFC 7606, specifying that AS_PATH with empty segment is considered malformed.
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.

2015-02-21Fixes potential alignment bug in BGP.Ondrej Zajicek
Thanks to Andrew (seti.kr.ua) for the bug report.
2014-10-24Integrated IP functions.Ondrej Zajicek
2013-12-01Finishes add-path.Ondrej Zajicek
Fixes some bugs and uses generic hash implementation.
2013-11-23Merge branch 'master' into add-pathOndrej Zajicek
Conflicts: filter/filter.c nest/proto.c nest/rt-table.c proto/bgp/bgp.h proto/bgp/config.Y
2013-10-21Implements 'allow local as' option.Ondrej Zajicek
Similar to allowas-in option on other routers.
2013-04-16Implements 'next hop keep' option for BGP.Ondrej Zajicek
This option allows to keep the received next hop even in cases when the route is sent to an interface with a different subnet.
2012-11-12AS# in bgp.agreggator was a signed integer - fixed.Ondrej Filip
2012-11-10Allows rejected routes to be kept and examined.Ondrej Zajicek
When 'import keep rejected' protocol option is activated, routes rejected by the import filter are kept in the routing table, but they are hidden and not propagated to other protocols. It is possible to examine them using 'show route rejected'.
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.

2012-01-20Fixes a new bug in BGP route ordering.Ondrej Zajicek
2012-01-08Implements support for link-local addresses in BGP.Ondrej Zajicek
Thanks Matthias Schiffer for the original patch.
2011-12-22Implements deterministic MED handling.Ondrej Zajicek
Thanks to Alexander V. Chernikov for many suggestions.
2011-09-03Fixes possible buffer overflow when printing BGP attributes.Ondrej Zajicek
Thanks to Alexander V. Chernikov for the patch.

2011-07-03Prints full community lists during 'show route all'.Ondrej Zajicek
2011-04-22Adds BGP option related to MED handling.Ondrej Zajicek
Adds option 'med metric' allows to compare MEDs between routes received from different neighbors.
2011-03-30Fixes some problems in BGP error handling.Ondrej Zajicek
2010-12-07Core multipath support.Ondrej Zajicek
2010-07-31Implements IGP metric comparison for BGP routes.Ondrej Zajicek
2010-07-28Adds route resolvability test.Ondrej Zajicek
2010-07-12Implements proper multihop BGP.Ondrej Zajicek
Also does some incompatible changes to config file syntax, like removing 'via IP' from multihop option.
2010-07-05Implements hostcache and recursive next hops.Ondrej Zajicek
Hostcache is a structure for monitoring changes in a routing table that is used for routes with dynamic/recursive next hops. This is needed for proper iBGP next hop handling.
2010-04-08Do not export empty community list attribute in BGP.Ondrej Zajicek
2010-02-26Comparing cluster list length should be later in bgp_rte_better().Ondrej Zajicek
2010-02-21Fix configure to enable warnings and fix most of them.Ondrej Zajicek
2010-02-13Removes phantom protocol from the pipe design.Ondrej Zajicek
It seems that by adding one pipe-specific exception to route announcement code and by adding one argument to rt_notify() callback i could completely eliminate the need for the phantom protocol instance and therefore make the code more straightforward. It will also fix some minor bugs (like ignoring debug flag changes from the command line).
2010-01-28Changes 'ignore communities' to 'interpret communities'.Ondrej Zajicek
2010-01-27Better handling of well-known communities.Ondrej Zajicek
Process well-known communities before the export filter (old behavior is to process these attributes after, which does not allow to send route with such community) and just for routes received from other BGP protocols. Also fixes a bug in next_hop check.
2009-12-21Change default LOCAL_PREF attribute to 100 (suggested value by RFC 4277).Ondrej Zajicek
