2020-06-03Netlink: Fix parsing of MPLS multipath routesKazuki Yamaguchi
Add support for RTA_MULTIPATH attribute parsing for AF_MPLS routes. BIRD is capable of installing a multipath route into kernel on Linux, but it would not be seen because parsing fails. This made BIRD attempt to install the same route repeatedly. (The patch minorly updated by committer)

This is merely a const propagation. There was no problem in there.

2020-02-27BGP: Support for MD5SIG together with remote rangeOndrej Zajicek (work)
When dynamic BGP with remote range is configured, MD5SIG needs to use newer socket option (TCP_MD5SIG_EXT) to specify remote addres range for listening socket. Thanks to Adam Kułagowski for the suggestion.
2019-12-19KRT: Remove KRF_SYNC_ERROR flagOndrej Zajicek (work)
This info is now stored in an internal bmap. Unfortunately, net.flags is still needed for temporary kernel data.
2019-11-12Netlink: Handle IPv4 routes with IPv6 nexthopsOndrej Zajicek
Accept RTA_VIA attribute in all cases. The old code always used RTA_GATEWAY for IPv4 / IPv6 and RTA_VIA for MPLS. The new code uses RTA_VIA in cases where AF of network and AF of nexthop differs.

2019-07-15Netlink: Use route replace for IPv4Ondrej Zajicek (work)
Use route replace netlink op instead of delete+add netlink ops for kernel IPv4 route replace. This avoids some packetloss during route replace. Still use the old behavior for IPv6, as some kernel bugs are hidden in IPv6 ECMP handling.

2019-07-02Netlink: Handle alien routes with unsorted nexthopsOndrej Zajicek (work)
Nest requires that nexthops are sorted, the kernel protocol have to ensure that for alien routes.
2019-07-02Netlink: Do unified scan for both IPv4 and IPv6Ondrej Zajicek (work)
Instead of separate scans for IPv4, IPv6 and MPLS, do one AF_UNSPEC scan. This also avoids kernel issue when kernel reported IPv4 and IPv6 routes during MPLS scan if MPLS is not active.
2019-02-20Filter refactoring: dropped the recursion from the interpreterMaria Matejka
This is a major change of how the filters are interpreted. If everything works how it should, it should not affect you unless you are hacking the filters themselves. Anyway, this change should make a huge improvement in the filter performance as previous benchmarks showed that our major problem lies in the recursion itself. There are also some changes in nest and protocols, related mostly to spreading const declarations throughout the whole BIRD and also to refactored dynamic attribute definitions. The need of these came up during the whole work and it is too difficult to split out these not-so-related changes.

2018-06-26Config: Dropping CF_ADDTO.Jan Maria Matejka
2018-05-30Nest: Removing separate tmpa from route propagationJan Maria Matejka
This is a fundamental change of an original (1999) concept of route processing inside BIRD. During import/export, there was a temporary ea_list created which was to be used instead of the another one inside the route itself. This led to some confusion, quirks, and strange filter code that handled extended route attributes. Dropping it now. The protocol interface has changed in an uniform way -- the `struct ea_list *attrs` argument has been removed from store_tmp_attrs(), import_control(), rt_notify() and get_route_info().

This supersedes the EAP_* constants.
2018-02-13Add support for source-specific IPv6 routes to BIRD coreOndrej Zajicek (work)
This patch adds support for source-specific IPv6 routes to BIRD core. This is based on Dean Luga's original patch, with the review comments addressed. SADR support is added to network address parsing in confbase.Y and to the kernel protocol on Linux. Currently there is no way to mix source-specific and non-source-specific routes (i.e., SADR tables cannot be connected to non-SADR tables). Thanks to Toke Hoiland-Jorgensen for the original patch. Minor changes by Ondrej Santiago Zajicek.

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.
2017-09-05KRT: Fix IPv6 ECMP handling with Linux 4.11+Ondrej Zajicek (work)
Starting from Linux 4.11, IPv6 ECMP routes are now notified using RTA_MULTIPATH, like IPv4 ones. The patch adds support for RTA_MULTIPATH parsing for IPv6 routes. This also enables to parse ECMP alien routes correctly. Thanks to Vincent Bernat for the original patch.
2017-07-04Implement onlink flag for nexthopsOndrej Zajicek (work)
Add proper support for per-nexthop onlink flag in routes to handle next hop addresses that are not covered by interface IP ranges. Supported by kernel and static protocols. Thanks to Vincent Bernat for the idea.
