2018-07-28BSD: Use MSG_DONTROUTE for unicast packets on FreeBSDOndrej Zajicek (work)
BSD systems cannot use SO_DONTROUTE, because it does not work properly with multicast packets (perhaps it tries to find iface based on multicast group address). But we can use MSG_DONTROUTE sendmsg() flag for unicast packets. Works on FreeBSD, is ignored on OpenBSD and is broken on NetBSD (i guess due to integrated routing table and ARP table).
2017-09-04BSD: Fix alignment issueOndrej Zajicek (work)
Incorrect structure alignment breaks kernel routing table updates on FreeBSD/ARM (and perhaps other platforms). Thanks to Eugene Sevastyanov for the original patch.
2017-01-17Fix IP_HDRINCL usage on FreeBSD 11Ondrej Zajicek (work)
FreeBSD 11 changed endianity of ip_len field from host order to network order. Also DragonFly BSD allegedly expects network order here. Thanks to Olivier Cochard-Labbé for the patch.
2016-11-01BSD: Fix build on OpenBSD broken by previous commitOndrej Zajicek (work)
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.
2016-09-29Kernel socket missing err_hook fixJan Moskyto Matejka
Thanks to Tim Weippert for bugreport.
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.
2016-04-06KRT: 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.
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.

2015-05-12KRT: 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

2014-10-24Integrated IP functions.Ondrej Zajicek
2014-07-09Fixes a bug in BSD kernel interfacing code.Ondrej Zajicek
The bug was introduced in 05476c4d04a24bdb26fa64e05ab31bc36118f34e.
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
2014-02-26Fixes longstanding issue with interfaces staying in IF_TMP_DOWN.Ondrej Zajicek
Thanks to Pierluigi Rolando and others for the bugreport.
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

2012-08-14Implements ADD-PATH extension for BGP.Ondrej Zajicek
Allows to send and receive multiple routes for one network by one BGP session. Also contains necessary core changes to support this (routing tables accepting several routes for one network from one protocol). It needs some more cleanup before merging to the master branch.
