094d2bdb79 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.

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.

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.

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.

Prefix sets were broken beyond any repair and have to be reimplemented.

but the old interpretation was already inconsistent with
the documentation and broken.

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

Martin Mares
758458be05 Unified parsing of prefixes. 
Had to rename `prefix' in filters to `fprefix'.

ab1129c1bd Added skeleton Doc files for the whole developer's documentation. 2000-05-05 17:17:42 +00:00
Martin Mares
9a220cabbc #ifdef out lots of debugging information. 
The long resource/routing table dump printed upon startup is gone now
and if you wish to see it, just send bird SIGUSR1 or use the `debug'
commands.
 2000-05-04 20:52:28 +00:00
Pavel Machek
2337ade754 Moved documentation to top of file, where it belongs. 2000-04-30 18:47:48 +00:00

8c62d6e3b6 Minor documentation update. 2000-04-29 17:48:38 +00:00
Martin Mares
2edb31b097 Split CF_HDR section to CF_HDR (only includes) and CF_DEFINES (defines, 
C declarations etc.).

f71bded6e9 Bugfix in i_same (comparing of paths still does not work). 2000-04-26 09:30:12 +00:00
Pavel Machek

Pavel Machek
471bd6c30b Marked place where new enums belong. 2000-04-26 07:47:47 +00:00
Pavel Machek
94d9dfa47a Startup renamed to __startup: it is internal function and mj already 
uses word startup in other context.
 2000-04-26 07:31:45 +00:00
Pavel Machek
7d6eebae3b Create syntax sugar for add/delete/prepend, so xyzzy.prepend(123) is 
possible. That means that milestone 3 was reached.
 2000-04-20 10:25:51 +00:00

0150e5211a Cleaned up mess with types in e,a and e,S. Dynamic attributes should 
now work.
 2000-04-17 14:12:02 +00:00

913ce95b08 EAF_ORIGINATED done right. 2000-04-17 11:52:32 +00:00
Pavel Machek
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
Pavel Machek
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

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).

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
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 ,

I do not know if it is right since mj ingores talk once started :-(.
 2000-03-01 14:31:31 +00:00
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.

Pavel, please implement this as soon as possible.
 2000-01-16 17:49:32 +00:00

Pavel, please check my addition to filter/config.Y.
 1999-12-02 14:04:44 +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?

Pavel Machek
48f9e01954 Filters: write access to dynamic attributes should actually work. It 
would be nice to find method of testing such beasts.
 1999-11-24 12:04:32 +00:00
Pavel Machek
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.
 1999-11-18 14:01:36 +00:00

fd54b60266 ENUM's are now recognized as constants. 1999-11-15 11:36:09 +00:00
Pavel Machek
4515bdba4f Fixed order of arguments for function call. 
Enumeration types should work once CF_ENUM() is ready.

Created test.conf for testing of filters. (I'm currently thinking
about ./tests in root directory which will just fire all available
tests...)
 1999-11-11 13:55:39 +00:00

Pavel Machek
cb8034f42c First try on enumerational types. 
Mj's noassoc removed: this brings back shift/reduce conflict but
it makes parser actually work. Mj please check it. IF/THEN/ELSE still
will not work.
 1999-11-10 13:44:29 +00:00
Pavel Machek
2f702671b4 No more shift/reduce conflicts. 1999-11-10 13:07:18 +00:00

Pavel Machek
d3dd620b96 Filters: permit variables of prefix types, cleanup around 
variables. TODO list added, hopefully complete. Use new features of
filters in bird.conf
 1999-10-12 06:27:42 +00:00
Pavel Machek
720d911d77 Added constants of type prefix and pair, added their printing 1999-10-07 14:10:08 +00:00

7db7b7db60 Case arg { 1: printf "one"; } works. You can not use two commands

6542ece91a Function calling in filters works - somehow. Calling syntax is 
currently very ugly, beware. Variables are not really local - that
needs to be fixed.
 1999-07-01 09:11:21 +00:00
Martin Mares
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
Pavel Machek
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.
 1999-04-19 18:41:56 +00:00
Pavel Machek
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
Pavel Machek
38506f71b0 Sets of integers now actually work. Sets of IP will work as soon as 
compare function is ready.

23b1539bf9 Filters upgraded - a bit. Moved code to filter.c because it is where 
it belongs. (f-util.c stays there for auxiliary and non-important things.)
 1999-04-07 12:11:08 +00:00
Martin Mares
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.
 1999-04-05 20:10:31 +00:00

ba92164871 Update of filters towards new interface. 1999-03-29 20:21:28 +00:00
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.

Martin Mares
c9b6670608 Original expr' is back, filter expressions renamed to term'. 
In the future, we'll allow any filter term in place of `expr' and we'll
just evaluate it immediately, but not now as we have no evaluation
routines.
