2017-12-07Babel: More changes and bugfixesOndrej Zajicek (work)
Several changes and bugfixes in Babel, namely: - Exported route parameters stored directly in route table entry - Exported non-babel routes no longer stored in per-entry route list - Route update, selection and retraction simplified and fixed - Route feasibility is evalualated per update and stored with route - Unreachable route handling fixed, based on hold interval - Added 'show babel routes' command Overall, it fixes some issues with proper propagation of triggered updates, making Babel convergence after topology change almost instant.
2017-12-07Timers: Parse and format functions for microsecond timesOndrej Zajicek (work)
Date/time output (e.g. in logs, show commands) can use %f to specify subsecond time. By default, millisecond precision is used in output.
2017-07-04Implement onlink flag for nexthopsOndrej Zajicek (work)
Add proper support for per-nexthop onlink flag in routes to handle next hop addresses that are not covered by interface IP ranges. Supported by kernel and static protocols. Thanks to Vincent Bernat for the idea.
2017-04-25Nest: Update of show route cmdOndrej Zajicek (work)
Some code cleanup, multiple bugfixes, allows to specify also channel for 'show route export'. Interesting how such apparenty simple thing like show route cmd has plenty of ugly corner cases.

2017-04-12Client: multitable version of show routeJan Moskyto Matejka
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

2017-02-24Nexthop: Fixed hostentryJan Moskyto Matejka
2017-02-22Nest: names for nhu_state valuesJan Moskyto Matejka
It took too much time to analyze what's the meaning of nhu_state values so I spent less than the same amount of time documenting it.

2016-12-22MPLS: Label stack concatenation for recursive routesJan Moskyto Matejka
2016-12-22Netlink: MPLS routes in kernelJan Moskyto Matejka
Anyway, Bird is now capable to insert both MPLS routes and MPLS encap routes into kernel. It was (among others) needed to define platform-specific AF_MPLS to 28 as this constant has been assigned in the linux kernel. No support for BSD now, it may be added in the future.
2016-12-22Static: Protocol rework wrt. struct nexthop changes; MPLS label supportJan Moskyto Matejka
2016-12-22Nexthop: Support for label stack in nestJan Moskyto Matejka
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.
2016-12-07Merge branch 'int-new-rpki-squashed' (early part) into int-newJan Moskyto Matejka
2016-12-07BGP redesignOndrej Zajicek (work)
Integrated and extensible BGP with generalized AFI handling, support for IPv4+IPv6 AFI and unicast+multicast SAFI.
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"; }; } ...
2016-11-09 Unit Testing for BIRDOndrej Zajicek (work)
- Unit Testing Framework (BirdTest) - Integration of BirdTest into the BIRD build system - Tests for several BIRD modules Based on squashed Pavel Tvrdik's int-test branch, updated for current int-new branch.

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.
2016-09-15rt-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)

2016-05-10Build system reworked to one global Makefile with includes and no nestingJan Moskyto Matejka
Also removed the lib-dir merging with sysdep. Updated #include's accordingly. Fixed make doc on recent Debian together with moving generated doc into objdir. Moved Makefile.in into root dir Retired all.o and birdlib.a Linking the final binaries directly from all the .o files.
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.
2016-04-08Route 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.

2016-04-06KRT: Fix route learn scan when route changedOndrej Zajicek (work)
When a kernel route changed, function krt_learn_scan() noticed that and replaced the route in internal kernel FIB, but after that, function krt_learn_prune() failed to propagate the new route to the nest, because it confused the new route with the (removed) old best route and decided that the best route did not changed. Wow, the original code (and the bug) is almost 17 years old.
2016-02-10Updated RTA hashes to 32-bit values.Jan Moskyto Matejka
... and reworked the hashes a bit. Also added mem_hash function which just computes a hash of given memory block.
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.
