26d92bb892 A hack to distinguish if..else from else: in case. 
The old BIRD grammar needs two lookaheads to distinguish if..else from
else: in case, which caused the parser to fail on some combinations of
both expressions.

This patch replaces two tokens 'else' ':' by one token 'else:' to fix
that.

ba5c0057ed Extends pair set syntax, matching and deleting against clist. 
Expressions like (123,*) can be used in pair set literals, clists can be
matched against pair sets (community ~ pairset) and pair sets can be
used to specify items to delete from clists (community.delete(pairset)).

dfd48621d1 Replaces the algorithm for building balanced trees. 
Changes the time complexity of the algorithm from O(n^2) to O(n*log(n)).
This speeds up loading of huge DEC-IX config from 128 s to 15 s. It also
makes the code significantly simpler.

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.

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.

to next symbol and both 'aux2' and 'def' fields for value.

2bd2de0188 pair ~ community list matching works. 2000-04-17 11:49:21 +00:00
Pavel Machek
4444ed2b26 It is good idea to separate entries in list _somehow_. Adding/deleting 
to community lists from filters now works.
 2000-04-17 11:42:08 +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
Pavel Machek
159fa4cea9 Finish moving of path matching. Use int_set_print from core for 
printing community lists.
 2000-04-17 11:20:00 +00:00

2a40efa5e6 as_path_match moved to a-path.c 2000-04-17 11:11:33 +00:00
Pavel Machek
684c6f5a0e Path_getlen moved to nest and length was made callable from filters. 2000-04-17 11:06:39 +00:00
Pavel Machek
ecd25633bd Use printing routine from nest/ instead of our own. 2000-04-17 10:54:01 +00:00

4b641bab52 Path matching now actually works, including / * 1 2 3 * /. 2000-04-17 10:50:03 +00:00
Pavel Machek
e399b6f6ad Path and path matching seem to work, now. 2000-04-17 10:42:28 +00:00
Pavel Machek
afc54517db Prepend and creation of empty path should work, but it has strange 
syntax for now.
 2000-04-17 10:16:47 +00:00

0a40e97328 as_path_prepend is usable outside bgp. 2000-04-12 14:12:37 +00:00

66d573d490 Attribute type hack. 2000-04-12 13:55:30 +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 
linklist instead of array of signed integers for path mask.
 2000-04-12 13:07:53 +00:00
Pavel Machek
77de68825c BGP_PATH masks now actually work as data type. 2000-04-12 12:10:37 +00:00
Pavel Machek
78c6217c1e Path printing is now much nicer: not having to put it backward 
simplifies it. (Sorry for previous commit, cvs is naughty).

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
b157361533 SOURCE should really refer to rta->source, not rta->gw. 
Please check that all rta attributes are available, I guess that at
least rta->dest is missing.
 2000-04-01 09:15:10 +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
221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero() 
and other non-portable functions on all systems.
 2000-03-31 23:30:21 +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

Martin Mares
6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules, 
several debug() calls converted to DBG().

995e5894cd 1 less shift/reduce conflict 
print now takes arguments separated by ,

Martin Mares
db1326aa5e Dynamic attributes are now declared in per-protocol grammar files instead 
of filter/config.Y. Bird now compiles even if you disable RIP.

Removed RTA and IMPOSSIBLE tokens (unused).

Removed superfluous comment in filter.h.

I've tried to do my best, but Pavel, please check these changes.

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

would be nice to find method of testing such beasts.
 1999-11-24 12:04:32 +00:00

f31156ca21 Filters: first parts of extended attributes being read-write. It can 
not actually work since I do not do rta/rte cow, yet.
 1999-11-18 14:29:10 +00:00
Pavel Machek
c7b43f33ae Split inst->code into inst->code and inst->aux. Both are only 16 bit, 
so aux is suitable for storing type but not much more.

4515bdba4f Fixed order of arguments for function call. 
Enumeration types should work once CF_ENUM() is ready.

about ./tests in root directory which will just fire all available
tests...)

Mj's noassoc removed: this brings back shift/reduce conflict but
it makes parser actually work. Mj please check it. IF/THEN/ELSE still

currently very ugly, beware. Variables are not really local - that

4107df1d1b Implemented two new symbol handling functions: 
o  cf_define_symbol() -- it assigns a meaning to a symbol, bailing
     out if it already has one.
  o  cf_find_symbol() -- finds symbol by name and creates it if not found.

Also modified filter/config.Y to make use of the first function.
 1999-05-17 20:06:19 +00:00

36bbfc704c Updated filters: they now actually see IP/pxlen of net being filtered, 
gateway, and who told us, so they can do usefull jobs from now on.

43fc099b98 Sets of IP addresses should work, now. (From now on it is also 
possible to write if 1.2.3.4 < 1.2.3.5, but I'm not sure if it is good
for anything.)
 1999-04-13 11:40:04 +00:00

63a381dbf5 Several filter changes. (Pavel, please check if they are OK.) 
o  Changed parameters of f_run. Changed rtein+rteout pair to rte pointer
      passed by reference, added ea_list of temporary attrs again passed
      by reference and finally added a pointer to memory pool for storing
      temporary data (new ea_lists's, temporary rta's etc.).
   o  Re-ordered result codes, so that all accepts come before all rejects.
   o  Introduced FILTER_ACCEPT and FILTER_REJECT dummy values (will be
      used in protocol configurations).
   o  Added filter_name() which returns name of a filter or ACCEPT/REJECT
      for the dummies.

Martin Mares
e0f2e42f4f A couple of filter tweaks: 
o  Introduced struct filter which serves as an external reference
      to filter. Using struct symbol for this is unwise since it doesn't
      allow extra information attached to the filter and it also forces
      all filters to be named.
   o  Implemented config rule 'filter' which matches either named filter
      or an embedded unnamed filter (`{ <filter> }').
   o  Fixed totally bogus comment at the top of filter.h.
   o  Added a missing prototype for f_run() to filter.h.

c9b6670608 Original expr' is back, filter expressions renamed to term'.
