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.
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.

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
2013-09-16BFD work in progress.Ondrej Zajicek
Now it compiles and mostly works.
2013-06-11Implements OSPF stub router option (RFC 3137).Ondrej Zajicek
Also fixes OSPFv3 routing table calculcation w.r.t. errata 2078 to RFC 5340.
2012-11-15Change unnamed ptp link description on OSPFv2.Ondrej Zajicek
Although it is a slight deviation from the standard, it has no ill consequences for OSPFv2 and the change fixes a compatibility issue with some broken implementations.

Mainly changes IA_UNNUMBERED to IA_PEER and adds IA_HOST. Also do not show broadcast addr in show interfaces. Nobody cares for that.

Now it can handle a change in iface pattern structure. It can add, remove and reconfigure interfaces, vlinks and areas.
