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.
2016-04-06KRT: 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.
2016-03-30IO/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.
2016-02-11Unix: Fix bug in syslog name handlingOndrej Zajicek (work)
Pointer to current_log_name has to be changed even if the name is the same, because the old one will be invalid/freed after reconfiguration.
2015-11-24Netlink: attribute validation before parsingJan Moskyto Matejka
Wanted netlink attributes are defined in a table, specifying their size and neediness. Removing the long conditions that did the validation before. Also parsing IPv4 and IPv6 versions regardless on the IPV6 macro.
2015-11-23Nest: Fix bug in device protoOndrej Zajicek (work)
If an interface address notification is received during device protocol shutdown/restart, BIRD crashed. Thanks to Wei Huang for the bugreport.

2015-11-11Netlink: Allow more than 256 routing tables.Jan Moskyto Matejka
Since 2.6.19, the netlink API defines RTA_TABLE routing attribute to allow 32-bit routing table IDs. Using this attribute to index routing tables at Linux, instead of 8-bit rtm_table field.
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.
2015-11-03IO: 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.

Kernel option 'merge paths' allows to merge routes exported to kernel protocol (currently BGP and static routes) to multipath routes.

2015-05-12KRT: Add support for plenty of kernel route metricsOndrej Zajicek
Linux kernel route metrics (RTA_METRICS netlink route attribute) are represented and accessible as new route attributes: krt_mtu, krt_window, krt_rtt, krt_rttvar, krt_sstresh, krt_cwnd, krt_advmss, krt_reordering, krt_hoplimit, krt_initcwnd, krt_rto_min, krt_initrwnd, krt_quickack, krt_lock_mtu, krt_lock_window, krt_lock_rtt, krt_lock_rttvar, krt_lock_sstresh, krt_lock_cwnd, krt_lock_advmss, krt_lock_reordering, krt_lock_hoplimit, krt_lock_rto_min, krt_feature_ecn, krt_feature_allfrag

2015-04-25KRT: Fixes learning of preferred kernel routes.Ondrej Zajicek
When a new route was imported from kernel and chosen as preferred, then the old best route was propagated as a withdraw to the kernel protocol. Under some circumstances such withdraw propagated to the BSD kernel could remove the new alien route and thus reverting the import.

Unfortunately, some interfaces support multicast but do not have this flag set, so we use it only as a positive hint. Thanks to Clint Armstrong for noticing the problem.

Also hook feed_done is renamed to feed_end.

Using 'dump sockets' in IPv6 mode caused crash due to mismatched format string. Thanks to Pavel Tvrdik for noticing it.
