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).

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.
2018-05-03Better initialization of random generatorOndrej Zajicek (work)
Use full time precision to initialize random generator. The old code was prone to initialize it to the same values in specific circumstances (boot without RTC, multiple VMs starting at once).

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.

Internal table used for route learn was created with non-matching net type for IPv6 kernel proto. Thanks to Toke Hoiland-Jorgensen for the bugreport

2018-01-23IO: Fix socket priorityOndrej Zajicek (work)
On Linux, setting the ToS will also set the priority and the range of accepted values is quite limited (masked by 0x1e). Therefore, 0xc0 is translated to a priority of 0, not something we want, overriding the "7" priority which was set previously explicitely. To avoid that, just move setting priority later in the code. Thanks to Vincent Bernat for the patch.

2018-01-16Filter: Allow silent filter executionOndrej Zajicek (work)
A filter should log messages only if executed explicitly (e.g., during route export or route import). When a filter is executed for technical reasons (e.g., to establish whether a route was exported before), it should run silently.

2018-01-14KRT: Fix direct routes for BSDOndrej Zajicek (work)
Old way to set direct routes is to use local IP as gateway, but that does not work properly on newer FreeBSDs. Now we use sockaddr_dl containing interface index as gateway.

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.
2017-09-04BSD: 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.
2017-07-04Implement 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.
