2017-12-08Enable ECMP and Link detection by defaultOndrej Zajicek (work)
ECMP is not enabled on BSD, where it is not supported by BIRD.
2017-12-07Merge commit '7b2c5f3d2826e3175bf31b1c36056c9efc587a2b' into int-newOndrej Zajicek (work)
2017-12-07Timers: Revert temporary names and remove old timer.hOndrej Zajicek (work)
2017-12-07Timers: Fix TBF and some last remainsOndrej Zajicek (work)
2017-12-07BGP: Update to new timersOndrej Zajicek (work)
2017-12-07OSPF: Update to new timersOndrej Zajicek (work)
Note that recurrent timers are currently limited to ~1 hour.
2017-12-07Timers: Show sub-second times in some protocol outputsOndrej Zajicek (work)
2017-12-07Timers: Replace old timers with microsecond timersOndrej Zajicek (work)
The old timer interface is still kept, but implemented by new timers. The plan is to switch from the old inteface to the new interface, then clean it up.
2017-10-10OSPF: Add option to disable OSPFv3-AFOndrej Zajicek (work)
2017-10-10OSPF: Fix minor issue in TTL checkOndrej Zajicek (work)
The TTL check must be done after instance ID dispatch to avoid warnings when a physical iface is shared by multiple instances and some use TTL security and some not.
2017-10-10OSPF: Fix next hop calculation for PtP links in IPv4 OSPFv3-AFOndrej Zajicek (work)
In such case, next hop has to be taken from Link-LSA like in broadcast case, not from neighbor source address like in other PtP cases. Also add some checks, comments and code cleanup.
2017-10-10OSPF: Support of address families in OSPFv3Ondrej Zajicek (work)
OSPFv3-AF can handle multiple topologies of diferent address families (IPv4, IPv6, both unicast and multicast) using separate instances distinguished by instance ID ranges.
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.
2017-05-23Change parser to handle numbers as unsignedOndrej Zajicek (work)
Lexer always parsed numbers as unsigned, but parser handled them as signed and grammar contained many unnecessary checks for negativity.

2016-12-22Nexthop: Support for label stack in nestJan Moskyto Matejka
2016-12-22Removing (struct rta)->cast. Never used.Jan Moskyto Matejka
2016-12-22Merged multipath and single-path data structures.Jan Moskyto Matejka
Dropped struct mpnh and mpnh_*() Now struct nexthop exists, nexthop_*(), and also included struct nexthop into struct rta. Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed to distinguish between these two cases, RTD_DEVICE is equivalent to IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw). From now on, we also explicitely want C99 compatible compiler. We assume that this 20-year norm should be known almost everywhere.
2016-12-15OSPF: Fix ECMP external mergingOndrej Zajicek (work)
The variable nfa is not cleaned before each loop iteration and can have a wrong value of nfa.nhs_reuse from the previous step. Thanks to Bernardo Figueiredo for the bugreport and analysis.
2016-12-13OSPF: Fix net-summary origination combined with stubnet optionOndrej Zajicek (work)
Stubnet nodes in OSPF FIB were removed during rt_sync(), but the pointer remained in top_hash_entry.nf, so net-summary LSA origination was confused, reported 'LSA ID collision' and net-summary LSAs were not originated properly. Thanks to Naveen Chowdary Yerramneni for bugreport and analysis.
2016-11-09 Unit Testing for BIRDOndrej Zajicek (work)
- Unit Testing Framework (BirdTest) - Integration of BirdTest into the BIRD build system - Tests for several BIRD modules Based on squashed Pavel Tvrdik's int-test branch, updated for current int-new branch.

Based on former commit from Pavel Tvrdik
2016-11-02Add generic message authentication interfaceOndrej Zajicek (work)
Add generic interface for generating and verifying MACs (message authentication codes). Replace multiple HMAC implementation with a generic one.
2016-11-01Build: switch on -Wextra, get rid of most of the warningsJan Moskyto Matejka
There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.

2016-05-10Build system reworked to one global Makefile with includes and no nestingJan Moskyto Matejka
Also removed the lib-dir merging with sysdep. Updated #include's accordingly. Fixed make doc on recent Debian together with moving generated doc into objdir. Moved Makefile.in into root dir Retired all.o and birdlib.a Linking the final binaries directly from all the .o files.
2016-04-08Route update: move table lookup from protocols into rte_update2().Jan Moskyto Matejka
Many protocols do almost the same when creating a rte_update request before calling rte_update2(). This commit should simplify the protocol side of the route-creation routine.

2016-03-23OSPF: Fix bogus LSA ID collisions between received and originated LSAsOndrej Zajicek (work)
After restart, LSAs locally originated by the previous instance are received from neighbors. They are installed to LSA db and flushed. If export of a route triggers origination of a new external LSA before flush of the received one is complete, the check in ospf_originate_lsa() causes origination to fail (because en->nf is NULL for the old LSA and non-NULL for the new LSA). The patch fixes this by updating the en->nf for LSAs being flushed (as is already done for empty ones). Generally, en->nf field deserves some better description in the code. Thanks to Jigar Mehta for analyzing the problem.
