Ondrej Zajicek f4c6ca8c9c Fixes preference bounds. 2009-09-17 13:35:37 +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.

 2008-12-25 17:49:57 +01:00
Ondrej Zajicek 083c43e22e fixes some 64-bit related bugs. 
Filter code used 'aux' integer field of 'symbol' struct to store ptr
to next symbol and both 'aux2' and 'def' fields for value.
Changed to just 'def' for value and 'aux2' for ptr to next symbol.
Also another minor bugfix.

show route where proto ~ "bgp1*"

Martin Mares 3b1c523d79 Got rid of startup functions and filters_postconfig().

Pavel Machek 2bd2de0188 pair ~ community list matching works. 2000-04-17 11:49:21 +00:00
Pavel Machek 991c36b509 Use EAF_ORIGINATED as mj wanted. mj: check this! 2000-04-17 11:37:05 +00:00
Pavel Machek 9c400ec9dd Int sets moved to core. It is now possible to have variable of type clist. 2000-04-17 11:34:38 +00:00

Martin Mares 2803c9ddbe Minor updates by Pavel. 2000-04-12 13:55:53 +00:00
Pavel Machek 10a5360886 Filters now know type path. It is possible to declare variable of type 
path, but it is not possible to write constant of type path.

It should be possible to print paths and match them.
 2000-04-12 13:31:39 +00:00
Pavel Machek dcab789047 Renamed f_path to f_path_mask -- which is what it really is. Use

 2000-04-12 10:34:45 +00:00
Pavel Machek 9196e9f8f9 Commit fixes. 2000-04-10 16:36:40 +00:00
Pavel Machek 7f77e25002 Functions for matching paths added, tested lightly. 
Functions for working with community lists added, they compile.

This should not be definitive place for this stuff.
 2000-04-10 15:07:43 +00:00
Martin Mares 798df5b1ab When processing ACCEPT/REJECT carrying no message, don't print 
trailing newline.

I hope the fix is correct, but please check.
 2000-04-01 09:15:55 +00:00
Martin Mares 3cf4a2e2b0 Removed lots of superfluous includes. 
Use debug() instead of printf().
 2000-03-31 23:35:59 +00:00
Martin Mares 3076b5aedc Renamed FF_OUTGOING to FF_FORCE_TMPATTR which much better fits the semantics. 
Call rte_cow() instead of rte_do_cow(), so that COW works properly.

Stripped "\n" off several (de)bug messages.
 2000-03-30 08:50:30 +00:00
Pavel Machek 0a06a9b8b3 f_run gets one more parameter to distinguish between in and out modes. 2000-03-29 09:02:00 +00:00
Martin Mares 81ce667b7b Don't crash when filter_same() gets called on FILTER_ACCEPT or FILTER_REJECT. 2000-03-12 22:40:07 +00:00
Martin Mares 6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules, 
several debug() calls converted to DBG().
 2000-03-12 21:01:38 +00:00
Pavel Machek 995e5894cd 1 less shift/reduce conflict 
print now takes arguments separated by ,

[ 1.2.3.0/24 .. 3.4.5.0/8 ] is now forbidden

[ 1.2.3.0/8 ] now actually works
 2000-03-09 14:47:43 +00:00
Martin Mares 9f4929e749 Renamed EAF_INLINE to EAF_TEMP to make the name reflect the real meaning. 2000-03-04 22:30:44 +00:00
Pavel Machek d4d7562806 Avoid being exponential, do not allow ! = 2000-03-02 22:23:18 +00:00
Pavel Machek 31e79264a2 tmp_attrs fixed. 
I do not know if it is right since mj ingores talk once started :-(.
 2000-03-01 14:31:31 +00:00

Pavel Machek 9a4037d408 filter_same() implemented. Don't bet on it, yet. 2000-01-31 17:44:22 +00:00
Martin Mares 30a6108ccc Added filter_same() for comparision of two filters. 
Pavel, please implement this as soon as possible.
 2000-01-16 17:49:32 +00:00
Martin Mares 2ad6dcdb2c Make ACCEPT/REJECT actually return the result... 1999-12-01 15:07:06 +00:00
Pavel Machek 7e1f99719e accept should behave as return, not running any commands after it. 1999-12-01 12:54:23 +00:00
Pavel Machek 6781e5213b FIXME's cleaned up: I have actually fixed things without killing 
comments.

There are no urgent FIXME's in filters. Perhaps we should start with
documentation?
 1999-12-01 11:39:58 +00:00
