Ondrej Zajicek a03ede6493 Fixes a tricky bug in route filtering. 
Route attributes was used after rta was freed during copy-on-write in
filter code. This causes some random crashes, esp. with multipath
routes.

used to specify items to delete from clists (community.delete(pairset)).

makes the code significantly simpler.

Ondrej Filip a6c9f0648d Missing boolean comparison added. 2009-05-28 13:37:04 +02:00
Ondrej Zajicek c8a6b9a3d1 Rewrite of buggy AS path matching. 
Old AS path maching supposes thath AS number appears
only once in AS path, but that is not true. It also
contains some bugs related to AS path sets.

New code does not use any assumptions about semantic
structure of AS path. It is asymptotically slower than
the old code, but on real paths it is not significant.

It also allows '?' for matching one arbitrary AS number.
 2009-04-17 01:48:36 +02:00
Ondrej Zajicek b1a597e0c3 Reimplementation of prefix sets. 
Prefix sets were broken beyond any repair and have to be reimplemented.
They are reimplemented using a trie with bitmasks in nodes.
There is also change in the interpretation of minus prefix pattern,
but the old interpretation was already inconsistent with
the documentation and broken.

There is also some bugfixes in filter code related to set variables.
