2021-03-16OSPFv3: Update neighbor authentication state from Hello packetsOndrej Zajicek (work)
In OSPFv3, only Hello and DBDes packets contain flags specifying whether RFC 7166 authentication trailer is used. Other packets are processed based on stored authentication state in neighbor structure. Update this state with each received Hello to handle authentication change from reconfigurations. Thanks to Joakim Tjernlund and Kenth Eriksson for the bugreport.
2019-07-10OSPF: Fix handling of NSSA option flagsOndrej Zajicek (work)
Per RFC 3101, N-bit signalling NSSA support should be used only in Hello packets, not in DBDES packets. BIRD since 2.0.4 verifies N-bit in neighbor structure, which is learned from DBDES packets, therefore NSSA-LSAs are not propagated to proper implementations of RFC 3101. This patch fixes that. Both removing the check and removing N-bit from DBDES packet. This will fix compatibility issues with proper implementations, but causes compatibility issues with BIRD 2.0.4.
2018-10-25OSPF: Fix some trace messagesOndrej Zajicek (work)
Missing argument in MTU change trace message can crash bird when MTU change happens and trace messages are active. Thanks to Alexander Velkov for the bugreport.
2018-04-25OSPF: Support of authentication trailer for OSPFv3Ondrej Zajicek (work)
Implement RFC 7166, crypthographic authentication for OSPFv3 analogous to authentication used for OSPFv2.
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.

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.
2015-11-12Follow-up commit on integrated BIRDOndrej Zajicek (work)
Use net_addr for interface address prefixes, support net_addr in configuration parser.
2015-11-05Initial commit on integrated BIRDOndrej Zajicek (work)
New data types net_addr and variants (in lib/net.h) describing network addresses (prefix/pxlen). Modifications of FIB structures to handle these data types and changing everything to use these data types instead of prefix/pxlen pairs where possible. The commit is WiP, some protocols are not yet updated (BGP, Kernel), and the code contains some temporary scaffolding. Comments are welcome.

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

2013-04-17Fixes a compatibility issue in OSPFv2 PtP links.Ondrej Zajicek
BIRD used zero netmask in hello packets on all PtP links, not just on unnumbered ones. This patch fixes it and adds option 'ptp netmask' for overriding the default behavior. Thanks to Alexander V. Chernikov for the original patch.

2009-05-24Hello packets on PTP networks should have zero netmask.Ondrej Zajicek
This also ensures that misconfigured routers (one side ptp and one side broadcast) do not make adjacency.

2004-07-15Huge OSPF database redesign. Since now, all LSAs of all areasOndrej Filip
are in single database. This avoids duplication of external LSAs and fixes bug in external LSA distribution.
2004-07-14Multiple OSPF areas can be attached.Ondrej Filip
Origination of summary LSA works. Routing table calculation works. Virtual links works. Well, I hope, OSPF is fully compatible with RFC2328!!!!
2004-07-13Send hello just after interface is up.Ondrej Filip
This makes the adjacency forming faster. Minor code clean up.
