2016-12-07RPKI protocol with one cache server per protocolPavel Tvrdík
The RPKI protocol (RFC 6810) using the RTRLib (http://rpki.realmv6.org/) that is integrated inside the BIRD's code. Implemeted transports are: - unprotected transport over TCP - secure transport over SSHv2 Example configuration of bird.conf: ... roa4 table r4; roa6 table r6; protocol rpki { debug all; # Import both IPv4 and IPv6 ROAs roa4 { table r4; }; roa6 { table r6; }; # Set cache server (validator) address, # overwrite default port 323 remote "rpki-validator.realmv6.org" port 8282; # Overwrite default time intervals retry 10; # Default 600 seconds refresh 60; # Default 3600 seconds expire 600; # Default 7200 seconds } protocol rpki { debug all; # Import only IPv4 routes roa4 { table r4; }; # Set cache server address to localhost, # use default ports tcp => 323 or ssh => 22 remote 127.0.0.1; # Use SSH transport instead of unprotected transport over TCP ssh encryption { bird private key "/home/birdgeek/.ssh/id_rsa"; remote public key "/home/birdgeek/.ssh/known_hosts"; user "birdgeek"; }; } ...

There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.
2016-10-12Fixed memory bloating on kernel merge paths together with export filter.Jan Moskyto Matejka
Some memory was being allocated from bad linpool, not from the given one as they should. Thanks to Madhu and Justin Cattle for reporting this.
2016-09-15rt-table: Fix kernel protocol export filter memory bugPavel Tvrdik
Kernel protocol calls rt_export_merged(), which used @rte_update_pool for temporary allocations, supposing it is called from other functions from rt-table.c that handles locking and flushing of the linpool. Therefore, linpool was not flushed properly and memory leaked. Add linpool argument to rt_export_merged() and use @krt_filter_lp when called from kernel protocol. Thanks to Justin Cattle and Alexander Frolkin for the bugreport. (Commit squashed and updated by Ondrej Zajicek)

2016-04-08Route update: move table lookup from protocols into rte_update2().Jan Moskyto Matejka
Many protocols do almost the same when creating a rte_update request before calling rte_update2(). This commit should simplify the protocol side of the route-creation routine.

2016-02-01Channels - explicit links between protocols and tablesOndrej Zajicek (work)
The patch adds support for channels, structures connecting protocols and tables and handling most interactions between them. The documentation is missing yet.

2015-11-09Nest: Fixes bug in missing cleanup during table removalOndrej Zajicek (work)
When a table is removed during reconfiguration, a reference was not cleared in the old configuration, which breaks undo.
2015-11-09Conf: Fixes bug in symbol lookup during reconfigurationOndrej Zajicek (work)
Symbol lookup by cf_find_symbol() not only did the lookup but also added new void symbols allocated from cfg_mem linpool, which gets broken when lookups are done outside of config parsing, which may lead to crashes during reconfiguration. The patch separates lookup-only cf_find_symbol() and config-modifying cf_get_symbol(), while the later is called only during parsing. Also new_config and cfg_mem global variables are NULLed outside of parsing.
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.

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.

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.
