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.

2016-11-02OSPF: Use message authentication interfaceOndrej Zajicek (work)
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.

2016-03-23OSPF: 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.

Thanks to Pavel Tvrdik for noticing it.

2015-10-05Major RIP redesignOndrej Zajicek (work)
The new RIP implementation fixes plenty of old bugs and also adds support for many new features: ECMP support, link state support, BFD support, configurable split horizon and more. Most options are now per-interface.
2015-08-19OSPF: Fixes some issues with link detectionOndrej Zajicek
Thanks to Bernardo Figueiredo and Israel G. Lugo for the bugreport.
2015-07-20Static: Allows to specify attributes for static routesOndrej Zajicek
The patch adds suport for specifying route attributes together with static routes, e.g.: route 10.1.1.0/24 via 10.0.0.1 { krt_advmss = 1200; ospf_metric1 = 100; };

2015-05-01OSPF: Redesign LSA checksummingOndrej Zajicek
New LSA checksumming code separates generic Fletcher-16 and OSPF-specific code and avoids back and forth endianity conversions, making it much more readable and also several times faster.
2015-04-28OSPF: Fixes validation of LSA checksumsOndrej Zajicek
Prior to this patch, BIRD validates the OSPF LSA checksum by calculating a new checksum and comparing it with the checksum in the header. Due to the specifics of the Fletcher checksum used in OSPF, this is not necessarily correct as the checkbytes in the header may be calculated via a different means and end up with a different value that is nonetheless still correct. The documented means of validating the checksum as specified in RFC 905 B.4 is to calculate c0 and c1 from the unchanged contents of the packet, which must result in a zero value to be considered valid. Thanks to Chris Boot for the patch.
2015-04-18OSPF: Fixes handling of external routes with immediate gwOndrej Zajicek
The bug caused that received external LSAs with locally reachable next hops were ignored. I wonder why nobody noticed it sooner.

2014-02-06Many changes in I/O and OSPF sockets and packet handling.Ondrej Zajicek
I/O: - BSD: specify src addr on IP sockets by IP_HDRINCL - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO - Alternative SKF_BIND flag for binding to IP address - Allows IP/UDP sockets without tx_hook, on these sockets a packet is discarded when TX queue is full - Use consistently SOL_ for socket layer values. OSPF: - Packet src addr is always explicitly set - Support for secondary addresses in BSD - Dynamic RX/TX buffers - Fixes some minor buffer overruns - Interface option 'tx length' - Names for vlink pseudoifaces (vlinkX) - Vlinks use separate socket for TX - Vlinks do not use fixed associated iface - Fixes TTL for direct unicast packets - Fixes DONTROUTE for OSPF sockets - Use ifa->ifname instead of ifa->iface->name
