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.
2016-09-19KRT: Add krt_scope attributeOndrej Zajicek (work)
Add a new route attribute, krt_scope, to expose the Linux kernel route scope. Constants from /etc/iproute2/rt_scopes (prefixed by "ips_") are expected to be used with the attribute. Both import and export are supported. Also, the patch fixes device route export to the kernel, by setting link scope automatically.
2016-09-15KRT: Add kernel metric protocol optionOndrej Zajicek (work)
Kernel routes with different metrics do not clash with each other, therefore using dedicated metric value is a reliable way to avoid overwriting routes from other sources (e.g. kernel device routes). Although kernel route metric could already be set as a route attribute by filters, that is not consistent with the way how Linux kernel handles route metric - not just a route attribute, but a part of a route key.
2016-09-14KRT: Support for IPv6 ECMPOndrej Zajicek (work)
Linux represents IPv6 ECMP routes as a sequence of unipath routes with the same prefix. We have to translate between our representation (one route with multipath next hop) and the Linux representation in both directions. Proper learning of alien IPv6 ECMP routes still not supported. Thanks to Mikhail Sennikovskii for the original patch.
2016-07-20Netlink: Fix build with older headers missing IFA_FLAGSOndrej Zajicek (work)
2016-07-20Netlink: Ignore tentative addressesOndrej Zajicek (work)
Ignore tentative IPv6 addresses and wait until finish of Duplicate Address Detection (We got notification when an address is no longer tentative) to avoid problems when protocols try to use interfaces with tentative link-local addresses. Based on patch from Jan Moskyto Matejka
2016-05-10netlink: update struct msghdrStijn Tintel
The netlink code assumes an order for the members of struct msghdr. This breaks recvmsg and sendmsg with musl libc on mips64. Fix this by using designated initializers instead. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
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.
2015-11-24Netlink: 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.

2015-05-12KRT: 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
2015-03-31Understand IFF_MULTICAST flag on ifaces in LinuxOndrej Zajicek
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.

This value is specified in documentation.

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.
