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.
2015-10-05Major 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.
2015-06-08BGP multipath supportOndrej Zajicek
Kernel option 'merge paths' allows to merge routes exported to kernel protocol (currently BGP and static routes) to multipath routes.
2015-06-08Fixes subtle bug in temporary attribute handlingOndrej Zajicek
In some cases, export filter accessed attributes of a different route.
2015-06-08Fixes bug in pipe feeding when filtered routes are kept in tableOndrej Zajicek

2015-05-17Simplify flushing processOndrej Zajicek
Related to changes from previous patch.
2015-05-16Fix minor issue in pipe route propagationOndrej Zajicek
In some circumstances during reconfiguration, routes propagated by pipes to other tables may hang there even after the primary routes are removed. There is already a workaround for this issue in the code which removes these stale routes by flush process when source protocols are shut down. This patch is a cleaner fix and allows to simplify the flush process
2015-02-21Allows user data attached to f_trie_node structure.Ondrej Zajicek
Thanks to Alexander Chernikov for the patch.
2014-11-08Fixes error message in 'show route' cmd.Ondrej Zajicek
Message 'Network not in table' was not reported if a network node without any routes was found in a routing table.
2014-10-02Implements show route noexport option.Ondrej Zajicek
Shows routes that would be exported to the protocol but are rejected by the export filter.

2014-04-28Fixes 'show route export' w.r.t. protocols with different RA_* types.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.

2013-11-22Adds rate limiting to some log messages.Ondrej Zajicek
2013-07-24Fixes bug in protocol flushing and rtable pruning.Ondrej Zajicek
When route was propagated to another rtable through a pipe and then the pipe was reconfigured softly in such a way that any subsequent route updates are filtered, then the source protocol shutdown didn't clean up the route in the second rtable which caused stale routes and potential crashes.
2013-06-13Fixes problems with kernel routes multiple routing tables.Ondrej Zajicek
Temporary dummy routes created by a kernel protocol during routing table scan get mixed with real routes propagated from another kernel protocol through a pipe.

related to a respective protocol.
2013-02-08Implements router advertisements activated by received routes.Ondrej Zajicek
The RAdv protocol could be configured to change its behavior based on availability of routes, e.g., do not announce router lifetime when a default route is not available.
2013-01-10Separate import and receive limits.Ondrej Zajicek
They have different behavior w.r.t. filtered routes that are kept.
2012-11-16Fixes route tracing w.r.t. kept filtered routes.Ondrej Zajicek
2012-11-15Changes 'rejected' to 'filtered' in one of the last patches.Ondrej Zajicek
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.

2012-03-28Fixes responsiveness for protocol shutdown.Ondrej Zajicek
When a protocol went down, all its routes were flushed in one step, that may block BIRD for too much time. The patch fixes that by limiting maximum number of routes flushed in one step.
2012-03-15Better support for multitable protocols.Ondrej Zajicek
The nest-protocol interaction is changed to better handle multitable protocols. Multitable protocols now declare that by 'multitable' field, which tells nest that a protocol handles things related to proto-rtable interaction (table locking, announce hook adding, reconfiguration of filters) itself. Filters and stats are moved to announce hooks, a protocol could have different filters and stats to different tables. The patch is based on one from Alexander V. Chernikov, thanks.
