2017-12-07Timers: Revert temporary names and remove old timer.hOndrej Zajicek (work)
2017-12-07Timers: Add typecast to unit-converting macrosOndrej Zajicek (work)
2017-12-07RAdv: Update to new timersOndrej Zajicek (work)
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.
2017-12-07Nest: Maintain separate IPv4, IPv6 and LLv6 preferred addressesOndrej Zajicek (work)
Also redesign preferred address selection and update protocols to use appropriate preferred address. Based on a previous work by Jan Maria Matejka.
2017-09-12Nest: VRF support for neighbor cache and olock codeOndrej Zajicek (work)
Actually much simpler than expected.
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.
2017-08-30RAdv: Some style nitpicksOndrej Zajicek (work)
2017-08-30RAdv: Configure how long a dead prefix is advertisedMichal 'vorner' Vaner
2017-08-30RAdv: Buffer prefixes awhile after they disappearMichal 'vorner' Vaner
Keep a cache of all the relevant prefixes we send out. When a prefix appears, insert it into the cache. If it dies, keep it there for a while, marked as dead. Send out the dead prefixes with zero lifetime.
2017-08-30RAdv: Extract prefix option preparationMichal 'vorner' Vaner
Put the prefix option preparation into a separate function. We're going to reuse that bit of code.

2017-05-23Change parser to handle numbers as unsignedOndrej Zajicek (work)
Lexer always parsed numbers as unsigned, but parser handled them as signed and grammar contained many unnecessary checks for negativity.
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.
2016-05-17IO: Minor changes in socket AF handingOndrej Zajicek (work)
AF can be specified implicitly by saddr or daddr, flags SKF_V4ONLY and SKF_V6ONLY are to be removed.
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.
2016-04-07Channelize: rt_notify arg conversion table -> channelJan Moskyto Matejka
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.
2016-01-11Hidden AF_INET* inside sysdep/Jan Moskyto Matejka
2015-12-24Follow-up work on integrationOndrej Zajicek (work)
2015-12-19Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AFJan Moskyto Matejka
Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listen on v6, without setting the V6ONLY flag to catch both v4 and v6 traffic. Squashing and minor changes by Ondrej Santiago Zajicek
2015-11-12Follow-up commit on integrated BIRDOndrej Zajicek (work)
Use net_addr for interface address prefixes, support net_addr in configuration parser.
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.

2014-02-06Many changes in I/O and OSPF sockets and packet handling.Ondrej Zajicek
I/O: - BSD: specify src addr on IP sockets by IP_HDRINCL - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO - Alternative SKF_BIND flag for binding to IP address - Allows IP/UDP sockets without tx_hook, on these sockets a packet is discarded when TX queue is full - Use consistently SOL_ for socket layer values. OSPF: - Packet src addr is always explicitly set - Support for secondary addresses in BSD - Dynamic RX/TX buffers - Fixes some minor buffer overruns - Interface option 'tx length' - Names for vlink pseudoifaces (vlinkX) - Vlinks use separate socket for TX - Vlinks do not use fixed associated iface - Fixes TTL for direct unicast packets - Fixes DONTROUTE for OSPF sockets - Use ifa->ifname instead of ifa->iface->name
