2009-04-08Fixes broken cryptographic authentication in OSPFOndrej Zajicek
Cryptographic authentication in OSPF is defective by design - there might be several packets independently sent to the network (for example HELLO, LSUPD and LSACK) where they might be reordered and that causes crypt. sequence number error. That can be workarounded by not incresing sequence number too often. Now we update it only when last packet was sent before at least one second. This can constitute a risk of replay attacks, but RFC supposes something similar (like time in seconds used as CSN).
2009-04-06Fixes bug in OSPF packet retransmission.Ondrej Zajicek
If a DBDES packet from a master to a slave is lost, then the old code does not retransmit it and instead send a next one with the same sequence number. That leads to silent desynchronization of LSA databases.
2009-04-06Better OSPF packet tracing log messages.Ondrej Zajicek
Replaces old OSPF packet tracing messages with uniform messages with packet dumps.
2009-02-25Fixes another bug in packet retransmissions.Ondrej Zajicek
When slave was in full state, it didn't retransmit lost packets. That leads to OSPF connection locked in states loading-full.
2009-02-12Fixes bug in packet retransmissions.Ondrej Zajicek
When packet was lost during dbdes exchange, slave did not retransmit it. That leads to OSPF connection locked in states exchange-exstart.
2009-01-16Fixes some past config grammar update that caused password related regression.Ondrej Zajicek
2009-01-16One null-pointer dereference bugfix hidden in whitespace changesOndrej Zajicek
2009-01-13Fix typo.Ondrej Zajicek
2009-01-13Fix OSPF protocol error recovery behavior.Ondrej Zajicek
When OSPF neighbor state drops down to EXSTART, clear LSA request and retransmit lists, as specified by RFC. I hope that this will prevent oscillations between EXSTART and LOADING states, which sometimes happened. It also contains related fix from Yury Shevchuk that properly resets DB summary list iterator.

2009-01-11Move check for NULL before usage of variable.Ondrej Zajicek
2009-01-11Fixes bug in OSPFOndrej Zajicek
Checksum was not recalculated when LSA was changed and packets with bad checksum were sent.
2008-11-14OSPF routes appeared with random value of ospf_tag attribute.Ondrej Zajicek
This patch fixes it.
2008-11-08Proper format functions for ORIGINATOR_ID, CLUSTER_LISTOndrej Zajicek
2008-11-08Fix bugs in OSPF MD5 authentication. First bug is that defaultOndrej Zajicek
values for MD5 password ID changed during reconfigure, Second bug is that BIRD chooses password in first-fit manner, but RFC says that it should use the one with the latest generate-from. It also modifies the syntax for multiple passwords. Now it is possible to just add more 'password' statements to the interface section and it is not needed to use 'passwords' section. Old syntax can be used too.

2008-10-28Fixes some sloppiness of commit a3b70dc499b64f41aa776b5b4afee5c7bfb8dfa6.Ondrej Zajicek
2008-10-27Two new informative CLI commands for OSPF.Ondrej Zajicek
Two new CLI commands for OSPF giving nice informative (and still machine parsable) representation of OSPF network graph (based on datas from the LSA database). The first command (show ospf topology) shows routers, networks and stub networks, The second command (show ospf state) shows also external routes and area-external networks and routers propagated by given area boundary router.

2008-10-26Bugfix in LSA origination for PTP OSPF links.Ondrej Zajicek
The code generating LSAs for PTP OSPF links is buggy. The old behavior is that it generates PTP link if there is a full/ptp neighbor and stub link if there isn't. According to RFC 2328, the correct behavior is to generate stub link in both cases (in the first case together with PTP link). And because of buggy detection of unnumbered networks, for numbered networks the code creates stub links with 0.0.0.0/32.
