2018-07-19OSPF: Fix crash during route removalOndrej Zajicek (work)
The bug was introduced by an earler patch which removed additional eattr argument to rt_notify hook.
2018-07-06Nest: Fix race condition during reconfiguration, part 2Ondrej Zajicek (work)
If export filter is changed during reconfiguration and a route disappears between reconfiguration and refeed (e.g., if the route is a static route also removed during the reconfiguration), the route is not withdrawn. The issue was fixed for regular channels by an earlier patch. This patch fixes the issue for channels in RA_ACCEPTED mode (first-pass-the-filter), used by BGP with 'secondary' option.

2018-07-03Nest: Fix race condition during reconfigurationOndrej Zajicek (work)
If export filter is changed during reconfiguration and a route disappears between reconfiguration and refeed (e.g., if the route is a static route also removed during the reconfiguration), the route is not withdrawn. The patch fixes that by adding tx reconfiguration timestamp.
2018-07-01BGP: Use implicit-NULL label when announcing MPLS routes with local next-hopOndrej Zajicek (work)
We currently cannot assing local labels, but we can still be LSP egress router. Therefore when we announce labeled route with local next-hop, we should announce implicit-NULL label instead of rejecting it completely.
2018-07-01BGP: Fix parsing of MPLS withdrawalsOndrej Zajicek (work)
RFC 3107 was bit vague with regard to labeled withdrawals, RFC 8277 clarified that. The old code was incompatible with some implementations, namely with Juniper. Thanks to Vadim Fedorenko for the original patch.

2018-06-19Filter: fixed eattr cached pointerJan Maria Matejka
Use ACCESS_RTE to guard **f_rte, use ACCESS_EATTRS to guard **f_eattrs. Use f_rta_cow() before writing to rta or eattrs, use f_rte_cow() before writing preference (stored in rte). Do not access eattrs indirectly through (*f_rte)->attrs->eattrs, it is way too slow. The cached pointer is faster.

2018-06-13Babel: Fix handling of missing IPv4 next hopsOndrej Zajicek (work)
In case of missing IPv4 next hop, we should skip such routes on transmit and ignore such routes on receive. Thanks to Julian Schuh for the bugreport and Toke Hoiland-Jorgensen for the original patch.
2018-06-13BGP: Handle missing NEXT_HOP attribute properlyOndrej Zajicek (work)
RFC 7606 specifies handle-as-withdraw instead of session reset.
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().

Included are Makefile implicit rules to show the preprocessed source. When debugging something around this, it may be handy.
2018-05-24Do not initialize route metrics in import_control hookOndrej Zajicek (work)
During route export, the receiving protocol often initialized route metrics to default value in its import_control hook before export filter was executed. This is inconsistent with the expectation that an export filter would process the same route as one in the routing table and it breaks setting these metrics before (e.g. for static routes directly in static protocol). The patch removes the initialization of route metrics in import_control hook, the default values are already handled in rt_notify hook called after export filters. The patch also changed the behavior of OSPF to keep metrics when a route is reannounced between OSPF instances (to be consistent with other protocols) and the behavior when both ospf_metric1 and ospf_metric2 are specified (to have more expected behavior).
2018-05-16Filter: Add support for src filter op to access SADR source prefixOndrej Zajicek (work)
The patch allows to use 'net.src' to access SADR source prefix from filters. Thanks to Toke Hoiland-Jorgensen for the original patch for srclen.
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).
2018-05-03Babel: Add option to randomize router IDOndrej Zajicek (work)
When a Babel node restarts, it loses its sequence number, which can cause its routes to be rejected by peers until the state is cleared out by other nodes in the network (which can take on the order of minutes). There are two ways to fix this: Having stable storage to keep the sequence number across restarts, or picking a different router ID each time. This implements the latter, by introducing a new option that will cause BIRD to randomize a high 32 bits of router ID every time it starts up. This avoids the problem at the cost of not having stable router IDs in the network. Thanks to Toke Hoiland-Jorgensen for the patch.
2018-05-03Babel: Fix type of route entry router IDOndrej Zajicek (work)
The router ID being assigned to routes was a uint, which discards the upper 32 bits. This also has the nice side effect of echoing the wrong router ID back to other routers. Thanks to Toke Hoiland-Jorgensen for the patch.

2018-04-12BGP: Fix extended next hop handlingOndrej Zajicek (work)
For IPv4 with extended next hop, we use MP-BGP format and therefore no independent NEXT_HOP attribute. Thanks to Arvin Gan for the bugreport.
