859cbd75 04/14/2014 10:50 AM Ondrej Zajicek

Fixes a bug in (mainly) IPv6 BGP.

Stack variable may be used unitialized and that would lead to spurious
rta_free(), which may cause crash. The bug was introduced in 1.4.1 from
merging add-path branch.

Thanks to Peter Andreev for reporting it and Alexander V. Chernikov for...

4e7c974d 03/24/2014 06:22 PM Ondrej Zajicek

094d2bdb 08/14/2012 02:46 PM Ondrej Zajicek

Implements ADD-PATH extension for BGP.

Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

options.

Added Cisco and Quagga capability workaround option.

82a79586 02/27/2009 02:24 PM Ondrej Zajicek

Better handling of too long attributes

This patch extends the length for attributes from 1024 to 2048
(because both AS_PATH and AS4_PATH attributes take 2+4 B per AS).

If there is not enough space for attributes, Bird skips that
route group. Old behavior (skipping remaining attributes)...

cb530392 02/26/2009 01:23 PM Ondrej Zajicek

Rate limit for most abundant log messages

165a6227 12/24/2008 04:24 PM Ondrej Zajicek

(according to [RFC4486]) are added.

The current implementation leads to race condition when both sides...

Updated a comment.

11d4474c 02/22/2003 10:47 PM Martin Mares

Better selection of link-local NLRI addresses, at least for our own
address. Need to do it better for the other neighbors -- the current
solution works only if they use the standard 64+64 global addresses
and the interface identifier in lower 64 bits is the same as for the...

Unused variables in IPv6 code.

93a786cb 05/04/2000 08:30 PM Martin Mares

Removed a lot of unused variables.

Please try compiling your code with --enable-warnings to see them. (The
unused parameter warnings are usually bogus, the unused variable ones
are very useful, but gcc is unable to control them separately.)

cf3d6470 05/04/2000 08:02 PM Martin Mares

IPv6 BGP support finished. Also simplified the BGP stuff a bit.

1c1da87b 05/04/2000 09:03 AM Martin Mares

don't check presence of mandatory attributes. [draft-09]

7787ace6 04/20/2000 10:54 PM Martin Mares

Synced to draft-ietf-idr-bgp4-09.
