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.

2019-07-09OSPF: Fix handling of external routes on graceful restartOndrej Zajicek (work)
We need to flush learned external LSAs a bit later than other LSAs (after first feed after end of the graceful restart) to avoid flap of external routes.

2019-06-30OSPF: Support for graceful restartOndrej Zajicek (work)
Implement OSPFv2 (RFC 3623) and OSPFv3 (RFC 5187) graceful restart, for both restarting and helper sides. Graceful restart is initiated by 'graceful down' command.
2019-02-20Filter + Config: Fix bugs, tests and split symbols by typeMaria Matejka
2019-02-13OSPF: Basic support for DN-bit handling (RFC 4576)Ondrej Zajicek (work)
External LSAs originated by OSPF routers with VPN-PE behavior enabled are marked by DN flag and they are ignored by other OSPF routers with VPN-PE enabled.
2019-02-03OSPF: Reject duplicate DBDES packets after dead intervalOndrej Zajicek (work)
Master may free last DBDES packet immediately. Slave must wait dead interval before freeing last DBDES packet and then reject duplicate DBDES packets with SeqNumberMismatch.
2019-02-03OSPF: DD seqnum should be initialized only for first attemptsOndrej Zajicek (work)
After SeqNumberMismatch/BadLSReq, we should continue with the old seqnum++. The old code tries to do that by n->adj, but it was set nowhere.
2019-01-24OSPF: Opaque LSAs and Router Information LSAOndrej Zajicek (work)
Add support for OSPFv2 Opaque LSAs (RFC 5250) and for Router Information LSA (RFC 7770). The second part is here mainly for testing opaque LSAs.
2018-05-29Protocol: Introducing an enum protocol_classJan Maria Matejka
This supersedes the EAP_* constants.
2018-04-25OSPF: Support of authentication trailer for OSPFv3Ondrej Zajicek (work)
Implement RFC 7166, crypthographic authentication for OSPFv3 analogous to authentication used for OSPFv2.

2017-12-07OSPF: Update to new timersOndrej Zajicek (work)
Note that recurrent timers are currently limited to ~1 hour.
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.

2016-11-02OSPF: Use message authentication interfaceOndrej Zajicek (work)
Based on former commit from Pavel Tvrdik
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.
2015-12-29Move ID allocator to a separate file and use it also in OSPFOndrej Zajicek (work)

2015-12-19Removed BITS_PER_IP_ADDRESS, MAX_PREFIX_LENGTH, BIRD_AFJan Moskyto Matejka
Explicit setting of AF_INET(6|) in IP socket creation. BFD set to listen on v6, without setting the V6ONLY flag to catch both v4 and v6 traffic. Squashing and minor changes by Ondrej Santiago Zajicek
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.

2014-04-23Extends multipath support for OSPF.Ondrej Zajicek
Fixes cases where the same network or external route are propagated by several OSPF routes and some other corner cases in next hop construction and ECMP. Allows to specify whether external routes should be merged. Thanks to Peter Christensen for the original patch.
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

2013-06-25Implements TTL security for OSPF and RIP.Ondrej Zajicek

2013-06-24Better packet priority and traffic class handling.Ondrej Zajicek
Implements support for IPv6 traffic class, sets higher priority for OSPF and RIP outgoing packets by default and allows to configure ToS/DS/TClass IP header field and the local priority of outgoing packets.

Also fixes OSPFv3 routing table calculcation w.r.t. errata 2078 to RFC 5340.
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.
