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.
2020-11-18OSPFv3: Fix intra-area-prefix-LSA origination on DROndrej Zajicek (work)
When a new link-LSA is originated, we need to notify intra-area-prefix-LSA handling, like when a new link-LSA is received. Otherwise a new network prefix added to a DR is not propagated immediately. Thanks to Bala Sajja for the bugreport.
2020-11-12BFD: Better handling of BFD options in BGP configsOndrej Zajicek (work)
Merge multiple BFD option blocks in BGP configs instead of using the last one. That is necessary for proper handling of templates when BFD options are used both in a BGP template and in a BGP protocol derived from that template.
2020-11-12BFD: Fix superfluous reconfiguration of sessionsOndrej Zajicek (work)
2020-11-08BFD: Allow per-request session optionsOndrej Zajicek (work)
BFD session options are configured per interface in BFD protocol. This patch allows to specify them also per-request in protocols requesting sessions (currently limited to BGP).
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.
2020-08-31OSPF: Fixed a debug assertMaria Matejka
2020-08-12OSPF: Skip out-of-state packets earlierOndrej Zajicek (work)
Sometimes multicast OSPF packet is received when neighbor adjacency is not established. Such packet should be ignored earlier in packet processing as otherwise it causes strange error messages when OSPFv3 authentication is enabled.
2020-06-28Show info from multiple protocols when protocol is not specifiedOndrej Zajicek (work)
Most commands like 'show ospf neighbors' fail when protocol is not specified and there are multiple instances of given protocol type. This is annoying in BIRD 2, as many protocols have IPv4 and IPv6 instances. The patch changes that by showing output from all protocol instances of appropriate type. Note that the patch also removes terminating cli_msg() call from these commands and moves it to the common iterating code.
2020-06-10OSPF: Fix bad header length testOndrej Zajicek (work)
Thanks to Slava Aseev for the thorough bugreport.
2020-06-03RPKI: Fix unnecessary reconnection on reconfigurationKazuki Yamaguchi
Compare the new timing parameters with the old configuration, not with the temporary state of the current connection. The timing values in struct rpki_cache is updated by a version 1 End Of Data PDU, unless this behavior is suppressed by the configuration explicitly by the "keep" keyword. Consequently, every reconfiguration of BIRD triggers a reconnection even if it is not necessary.
2020-06-02OSPF: setting list node to zero before enlistingMaria Matejka
2020-05-26Babel: Set onlink flag for IPv4 routes with unreachable next hopOndrej Zajicek (work)
If the next hop of a route is not a reachable address, the route should be installed as onlink. This enables a configuration common in mesh networks where the mesh interface is assigned a /32 and babel handles the routing by installing onlink routes. Thanks to Toke Hoiland-Jorgensen for the patch.
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.

2020-05-01OSPF: variable-length array of size 0 replaced by alloca()'d pointerMaria Matejka
NULL pointer is safer than a random pointer onto stack if this function gets changed and eventually broken.
2020-04-29BGP: Fix handling of strange IPv6 link-local-only next hopsOndrej Zajicek (work)
There are three common ways how to encode IPv6 link-local-only next hops: (:: ll), (ll), and (ll ll). We use the first one but we should accept all three. The patch fixes handling of the last one. Thanks to Sebastian Hahn for the bugreport.
2020-04-28Not calling memcpy with n=0.Maria Matejka
2020-04-15BGP: Fix handling of 16bit-only ASN translationNasato Goto
The bug generated invalid AGGREGATOR attribute during translation of 32bit ASN to 16bit-only BGP peer. The patch fixes that.
2020-04-09Configuration strings are constant.Maria Matejka
This is merely a const propagation. There was no problem in there.
2020-03-14RIP: Improvements to demand circuit modeOndrej Zajicek (work)
Restart iface after changing demand circuit mode during reconfiguration. Fix next_regular interval reset during reconfiguration. Send flushing response when iface goes down.
2020-03-12Perf: changed route update pattern to be more like common protocolsMaria Matejka
2020-03-03BGP: Handle flowspec rules without dst partOndrej Zajicek (work)
The RFC 5575 does not explicitly reject flowspec rules without dst part, it just requires dst part in validation procedure for feasibility, which we do not implement anyway. Thus flow without dst prefix is syntactically valid, but unfeasible (if feasibilty testing is done). Thanks to Alex D. for the bugreport.
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.

2020-02-14RIP: Fix crash when interface is removedOndrej Zajicek (work)
Recent changes in neighbor code caused RIP to access neighbor field which is NULL during interface/neighbor removal and caused crash when debug messages are enabled. Use correct field to get iface from neighbor.
2020-02-04RPKI: Allow build without libSSHMaria Matejka
2020-01-28BFD: Option to specify which class of BFD sessions are acceptedOndrej Zajicek (work)
Allows to configure IPv4/IPv6-only or direct/multihop-only BFD protocol instances.
2020-01-09OSPF: Fix bad initialization of tx_hdrlen fieldOndrej Zajicek (work)
Function ifa_tx_hdrlen() uses fields autype and passwords, so it must be called after these are set. Thanks to Kenth Eriksson for the bugreport.
2019-12-03BGP: Add some statisticsOndrej Zajicek (work)
Add some statistic counters to BGP consistent with BGP MIB (RFC 4273), including persistent 'FSM established transitions'.
2019-11-18BGP: Fix processing of IPv6 FlowspecOndrej Zajicek (work)
During NLRI parsing of IPv6 Flowspec, dst prefix was not properly extracted from NLRI, therefore a received flow was stored in a different position in flowspec routing table, and was not reachable by command 'show route <flow>'. Add proper prefix part accessors to flowspec code and use them from BGP NLRI parsing code. Thanks to Alex D. for the bugreport.
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.
2019-11-04BGP: Add option to reject AS_SETsOndrej Zajicek (work)
There is a pending draft to make them obsolete

2019-10-24BGP: Fix handling of transitive extended communitiesOndrej Zajicek (work)
Transitive extended communities should be removed on external sessions, the old code them in all cases. Thanks to Jean-Daniel Pauget for the original patch.
2019-10-19RPKI: Fix handling of IPv6 cache addressesOndrej Zajicek (work)
The old code used just sizeof(struct sockaddr) bytes of IP address.
2019-10-10BGP: Fix reconfiguration with import tableOndrej Zajicek (work)
Change of some options requires route refresh, but when import table is active, channel reload is done from it instead of doing full route refresh. So in this case we request it internally.
2019-10-09BGP: AIGP metric support (RFC 7311)Ondrej Zajicek (work)
2019-10-09Lib: Support for 64-bit numbers in bvsnprintf()Ondrej Zajicek (work)
Use 'l' for s64/u64 instead of for long/ulong, as that is much more useful. Also make number() correct with regard to signed/unsigned typecasts.
2019-10-09Perf: allow testing with cached route attributes.Maria Matejka
2019-09-30BFD: Fix reconfiguration of neighborsOndrej Zajicek (work)
The bfd_reconfigure_neighbors() returned after first reconfigured neighbor instead of continuing with the next one. Thanks to Winston Chen for the bugreport and a patch.
2019-09-17BGP: Fix setup with multiple dynamic BGP rangesOndrej Zajicek (work)
Based on a patch from Liam Nattrass, thanks.
2019-09-09BGP: Fix handling of bgp_aggregator atttributeOndrej Zajicek (work)
The attribute should not be modifiable by filters as we do not support its type.
2019-09-09BGP: Fix bugs in handling of shutdown messagesOndrej Zajicek (work)
There is an improper check for valid message size, which may lead to stack overflow and buffer leaks to log when a large message is received. Thanks to Daniel McCarney for bugreport and analysis.
