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.

2016-05-12Prog Doc: Complete several missing parametersPavel Tvrdik
2016-05-10Merge branch 'int-new' into int-new-mergedJan Moskyto Matejka
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.

2016-04-13BSD: Add the IPsec SA/SP database entries controlOndrej Zajicek (work)
Add code for manipulation with TCP-MD5 keys in the IPsec SA/SP database at FreeBSD systems. Now, BGP MD5 authentication (RFC 2385) keys are handled automatically on both Linux and FreeBSD. Based on patches from Pavel Tvrdik.
2016-04-08Merge branch 'master' into int-new-channelsJan Moskyto Matejka
2016-04-06IO: Avoid multiple event cycles in one loop cycle.Ondrej Zajicek (work)
Event cycle may took too much time and trigger next timer events, so avoid cycling between timer and event cycles inside the loop cycle.
2016-04-06IO: Replace RX priority heuristic with explicit markOndrej Zajicek (work)
In BIRD, RX has lower priority than TX with the exception of RX from control socket. The patch replaces heuristic based on socket type with explicit mark and uses it for both control socket and BGP session waiting to be established. This should avoid an issue when during heavy load, outgoing connection could connect (TX event), send open, but then failed to receive OPEN / establish in time, not sending notifications between and therefore got hold timer expired error from the neighbor immediately after it finally established the connection.
2016-03-30IO/Poll: fix mistaken variable mergeJan Moskyto Matejka
The events variable is used in the short loop decision. The reasons are not much clear, keeping this to keep the former behaviour.
2016-03-18Unix: Substituted select -> poll also in congestion checkerJan Moskyto Matejka
It does strange things when even one fd larger than FD_SETSIZE is passed to select().
2016-03-15Poll: Prevent the improbable case of EAGAIN after POLLINJan Moskyto Matejka
2016-03-11Unix: Rework of select-loop to poll-loopJan Moskyto Matejka
This should lift the limit of FD_SETSIZE and allow more than 1024 fd's. FD_SETSIZE limit doesn't matter now when creating new sockets.
2016-01-27io.c: fix reads from uninitialized memoryPavel TvrdĂ­k
2016-01-11Hidden AF_INET* inside sysdep/Jan Moskyto Matejka
2015-12-22Better fix of missing AF_INET6? definition in lib/socket.hJan Moskyto Matejka
Moved the code to sysdep.
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
2015-11-03IO: Fix the previous bugfixOndrej Zajicek (work)
I should check it after making some trivial changes. The original patch from Alexander has it right.
2015-11-03IO: Handle fd values too big for select()Ondrej Zajicek (work)
If the number of sockets is too much for select(), we should at least handle it with proper error messages and reject new sockets instead of breaking the event loop. Thanks to Alexander V. Chernikov for the patch.
2015-04-19Fixes port range socket optionOndrej Zajicek
2015-03-02Fixes bug in debug dumpsOndrej Zajicek
Using 'dump sockets' in IPv6 mode caused crash due to mismatched format string. Thanks to Pavel Tvrdik for noticing it.
2015-03-02Implement latency tracking, internal event log and watchdogOndrej Zajicek
2015-02-22Use IP_PORTRANGE_HIGH for BFD where availableOndrej Zajicek
2014-10-24Integrated IP functions.Ondrej Zajicek
2014-10-02Fixes some warnings.Ondrej Zajicek
2014-06-26Ensures that msg_controllen includes last padding.Ondrej Zajicek
Although RFC 3542 allows both cases, Theo de Raadt thinks he knows better, and msg_controllen without last padding fails on OpenBSD. Thanks to Job Snijders for the bugreport.
2014-05-18IPv4/IPv6 integrated socket code.Ondrej Zajicek
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
2013-11-22Merge commit 'origin/bfd'Ondrej Zajicek
2013-11-22Fixes problem with RIP on multiple ifaces on BSD.Ondrej Zajicek
RIP sockets for multiple ifaces collided, because we cannot bind to a specific iface on BSD. Workarounded by SO_REUSEPORT. Thanks to Eugene M. Zheganin for the bugreport.

2013-07-11Some fixes for TTL security.Ondrej Zajicek
2013-06-25Implements TTL security for OSPF and RIP.Ondrej Zajicek
Interfaces for OSPF and RIP could be configured to use (and request) TTL 255 for traffic to direct neighbors. Thanks to Simon Dickhoven for the original patch for RIPng.
2013-06-24Better packet priority and traffic class handling.Ondrej Zajicek
Implements support for IPv6 traffic class, sets higher priority for OSPF and RIP outgoing packets by default and allows to configure ToS/DS/TClass IP header field and the local priority of outgoing packets.
2012-12-26Implements undo command and optional timeout for configurationOndrej Zajicek
Several new configure command variants: configure undo - undo last reconfiguration configure timeout - configure with scheduled undo if not confirmed in timeout configure confirm - confirm last configuration configure check - just parse and validate config file
