2018-07-03Nest: Fix race condition during reconfigurationOndrej Zajicek (work)
If export filter is changed during reconfiguration and a route disappears between reconfiguration and refeed (e.g., if the route is a static route also removed during the reconfiguration), the route is not withdrawn. The patch fixes that by adding tx reconfiguration timestamp.
2018-05-29Protocol: Introducing an enum protocol_classJan Maria Matejka
This supersedes the EAP_* constants.
2018-01-10Use non-fatal asserts even for regular buildOndrej Zajicek (work)
2018-01-09Nest: Allow modification of channels inherited from templatesOndrej Zajicek (work)
Multiple definitions of same channels are forbidden, but inherited channel can be redefined. In such case channel options are merged.
2018-01-09Nest: Fix filter reconfigurationOndrej Zajicek (work)
Function filter_same() must be called with arguments in proper order, otherwise it breaks the new filter, causing crash during route processing.

2017-12-07Timers: Show sub-second times in some protocol outputsOndrej Zajicek (work)
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.
2017-12-07Timers: Replace old timers with microsecond timersOndrej Zajicek (work)
The old timer interface is still kept, but implemented by new timers. The plan is to switch from the old inteface to the new interface, then clean it up.
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.
2017-09-06Basic VRF supportOndrej Zajicek (work)
Add basic VRF (virtual routing and forwarding) support. Protocols can be associated with VRFs, such protocols will be restricted to interfaces assigned to the VRF (as reported by Linux kernel) and will use sockets bound to the VRF. E.g., different multihop BGP instances can use diffent kernel routing tables to handle BGP TCP connections. The VRF support is preliminary, currently there are several limitations: - Recent Linux kernels (4.11) do not handle correctly sockets bound to interaces that are part of VRF, so most protocols other than multihop BGP do not work. This will be fixed by future kernel versions. - Neighbor cache ignores VRFs. Breaks config with the same prefix on local interfaces in different VRFs. Not much problem as single hop protocols do not work anyways. - Olock code ignores VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. - Incoming BGP connections are not dispatched according to VRFs. Breaks config with multiple BGP peers with the same IP address in different VRFs. Perhaps we would need some kernel API to read VRF of incoming connection? Or probably use multiple listening sockets in int-new branch. - We should handle master VRF interface up/down events and perhaps disable associated protocols when VRF goes down. Or at least disable associated interfaces. - Also we should check if the master iface is really VRF iface and not some other kind of master iface. - BFD session request dispatch should be aware of VRFs. - Perhaps kernel protocol should read default kernel table ID from VRF iface so it is not necessary to configure it. - Perhaps we should have per-VRF default table.
2017-05-23Minor cleanups and fixesOndrej Zajicek (work)
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.

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"; }; } ...

2016-04-07Nest: Reset export route counter during graceful restartOndrej Zajicek (work)
Counter exp_routes is increased during initial route feed after GR recovery, so it has to start with zero, otherwise BIRD will end with double value in exp_routes.

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.
2015-11-09Conf: 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.

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.

They have different behavior w.r.t. filtered routes that are kept.
