2020-11-12BFD: Update documentation about per-session optionsOndrej Zajicek (work)
2020-10-11RPKI: Add 'ignore max length' optionOndrej Zajicek (work)
Add 'ignore max length' option to RPKI protocol, which ignores received max length in ROA records and instead uses max value (32 or 128). This may be useful for implementing loose RPKI check for blackholes.

2020-05-26OSPF: Fix handling of unnumbered PtPsOndrej Zajicek (work)
This issue has a long history. In 2012, we changed data field for unnumbered PtP links from iface id (specified by RFC) to IP address based on reports of bugs in Quagga that required it, and we used out-of-band information to distinquish unnumberred PtPs with the same local IP address. Then with OSPF graceful restart implementation, we found that we can no longer use out-of-band information, and we need to use only LSAdb info for routing table calculation, but i forgot to finish handling of this case, so multiple unnumbered PtPs with the same local IP addresses were broken. Considering that even recent Mikrotik RouterOS has broken next hop calculation that depends on IP address in PtP link data field, we cannot just switch back to the iface id for unnumbered PtP links. The patch makes two changes: First, it goes back to use out-of-band (position) info for distinguishing local interfaces in SPF when graceful restart is not enabled, while still uses LSAdb-only approach for SPF calculation when graceful restart is enabled. Second, it adds OSPF interface option 'ptp address', which controls whether IP address or iface id is used in data field. It is enabled by default except for unnumbered PtP links with enabled graceful restart. Thanks to Kenth Eriksson for the bugreport and Joakim Tjernlund for suggestions.
2020-05-19Nest: Allow key id 0Ondrej Zajicek (work)
There is nothing in RFCs specifying that id 0 is not allowed. Some implementations does not support it, while some other use key id 0 by default. We allow it but start with key id 1 by default. Thanks to Kenth Eriksson for the bugreport.

2020-05-18Nest: Implement BGP path mask loop operatorOndrej Zajicek (work)
Implement regex-like '+' operator in BGP path masks to match previous path mask item multiple times. This is useful as ASNs may appear multiple times in paths due to path prepending for traffic engineering purposes.
2020-05-02Filter: Remove quitbird commandOndrej Zajicek (work)
No need for this debug filter command and it can be abused from CLI.

2019-11-10BGP: Add option to enforce first AS in AS_PATHOndrej Zajicek (work)
This is optional check described in RFC 4271. Although this can be also done by filters, it is widely implemented option in BGP implementations. Thanks to Eugene Bogomazov for the original patch.

2019-09-10Doc: Update BGP mask documentationOndrej Zajicek (work)
2019-08-14BGP: implement Adj-RIB-OutOndrej Zajicek (work)
The patch implements optional internal export table to a channel and hooks it to BGP so it can be used as Adj-RIB-Out. When enabled, all exported (post-filtered) routes are stored there. An export table can be examined using e.g. 'show route export table bgp1.ipv4'.
2019-08-12RAdv: Allow solicited RAs to be sent as unicastOndrej Zajicek (work)
Add option to send solicited router advertisements as unicast directly to soliciting nodes instead of as multicast to all-nodes group.
2019-07-31Change 'graceful down' command to 'graceful restart' and update docsOndrej Zajicek (work)
The command initiating planned graceful restart including bird shutdown should be called 'graceful restart' instead of 'graceful down', as the later should be reserved for graceful shutdown in style of RFC 8326.

2019-04-03BGP: Promiscuous ASN modeOndrej Zajicek (work)
Allow to specify just 'internal' or 'external' for remote neighbor instead of specific ASN. In the second case that means BGP peers with any non-local ASNs are accepted.

2018-12-18Perf: Protocol to measure BIRD performance internallyMaria Matějka
This protocol is highly experimental and nobody should use it in production. Anyway it may help you getting some insight into what eats so much time in filter processing.
2018-12-16BGP: Extend 'next hop keep' and 'next hop self' optionsOndrej Zajicek (work)
Extend 'next hop keep' and 'next hop self' options to have boolean values (enabled / disabled) and also values 'ibgp'/ 'ebgp' to restrict it to routes received from IBGP / EBGP. This allows to have it enabled by default in some cases, matches features of other implementations, and allows to handle some strange cases like EBGP border router with 'next hop self' also doing IBGP route reflecting. Change default of 'next hop keep' to enabled for route servers, and 'ibgp' for route reflectors. Update documentation for these options.

2018-12-06Custom route attributesMaria Matejka
For local route marking purposes, local custom route attributes may be defined. These attributes are seamlessly stripped after export filter to every real protocol like Kernel, BGP or OSPF, they however pass through pipes. We currently allow at most 256 custom attributes. This should be much faster than currently used bgp communities for marking routes.
2018-12-04Unix: Change debugging optionsOndrej Zajicek (work)
The old behavior was that enabling debugging did many nontrivial changes in BIRD behavior. The patch changes it that these changes are generally independent. Compiling with --enable-debug now just enables compile-time debug macros, but do not automatically activate debug mode (-d) nor local mode (-l). Debug mode with output to file (-D) do not force foreground mode (-f), therefore there is no need for backgroud option (-b), which is removed. Also fixes a bug when the default log target in -D mode was stderr instead of given debug file.

2018-11-05Filter: Make ifname attribute modifiableOndrej Zajicek (work)

Thanks to Clemens Schrimpe for the bugreport.
2018-08-21DOC: Remove pipe mode referenceOndrej Zajicek (work)

Thanks to Julien Dessaux for the report.
2018-07-31BGP: Long-lived graceful restartOndrej Zajicek (work)
The patch implements long-lived graceful restart for BGP, namely draft-uttaro-idr-bgp-persistence-03.
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).
2018-05-03Babel: 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.
