2021-05-18Flowspec: Do not use comma for bitmask operatorsOndrej Zajicek (work)
For numeric operators, comma is used for disjunction in expressions like "10, 20, 30..40". But for bitmask operators, comma is used for conjunction in a way that does not really make much sense. Use always explicit logical operators (&& and ||) to connect bitmask operators. Thanks to Matt Corallo for the bugreport.
2021-05-17Filter: Add MPLS label route attributeTrisha Biswas
Add support to set or read outgoing MPLS labels using filters. Currently this supports the addition of one label per route for the first next hop. Minor changes by committer.
2021-04-25Doc: Include full LinuxDocTools codeOndrej Zajicek (work)
BIRD uses hacked LinuxDocTools for building documentation, keeping some parts locally and using remaining parts from system-installed one. This setup breaks when LinuxDocTools makes some internal changes and is hard to keep consistent. Just include full LinuxDocTools code (both hacked and unmodified parts) to avoid consistency issues. Note that we still need some binaries from LinuxDocTools, so it still needs to be installed to build documentation.

2021-02-10BGP: Add support for BGP hostname capabilityVincent Bernat
This is an implementation of draft-walton-bgp-hostname-capability-02. It is implemented since quite some time for FRR and in datacenter, this gives a nice output to avoid using IP addresses. It is disabled by default. The hostname is retrieved from uname(2) and can be overriden with "hostname" option. The domain name is never set nor displayed. Minor changes by committer.
2021-01-07Doc: Describe per-nexthop static route optionsOndrej Zajicek (work)
Also remove description of (no longer supported) per-route 'bfd' option, and add examples of IPv6 routes with link-local nexthops.
2021-01-06BGP: Deprecate 'missing lladdr' optionOndrej Zajicek (work)
The option is not implemented since transition to 2.0 and no plan to add it. Also remove some deprecated RTS_* valus from documentation. Thanks to Sébastien Parisot for notification.
2020-12-02Filter: Add 'weight' route attributeOndrej Zajicek (work)
Add 'weight' route attribute that allows to get and set ECMP weight of nexthops. Similar to 'gw' attribute, it is limited to the first nexthop, but it is useful for handling BGP multipath, where an ECMP route is merged from multiple regular routes.
2020-11-19Static: Support for multiple routes with the same networkOndrej Zajicek (work)
Add support for proper handling of multiple routes with the same network to the static protocol. Routes are distinguished by internal index, which is assigned automatically (sequentially for routes within each network). Having different route preference or igp_metric attribute is optional.

2020-11-15Doc: Fix typoOndrej Zajicek (work)
Thanks to Hexhu for the bugreport.
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.

Thanks to Marco Gartmann for the bugreport.

2020-06-03Doc: Add 'ptp address' to OSPF doc overviewKenth Eriksson
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.

2019-06-30Nest: Add command to request graceful restartOndrej Zajicek (work)
When 'graceful down' command is entered, protocols are shut down with regard to graceful restart. Namely Kernel protocol does not remove routes and BGP protocol does not send notification, just closes the connection.

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.
