0d1b3c4c0e Changes print-like filter commands to use a log instead of a stderr. 
And extends the log subsystem to better handle that.

126683feed Filter language updates; new route attributes and datatype. 
- Adds bgp_originator_id and bgp_cluster_list route attributes.
 - Adds dotted quad filter datatype (for router IDs, used by
   bgp_originator_id and ospf_router_id route attributes).
 - Fixes pair ~ pair set matching.
 - Documentation updates.

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.

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.

3b1c523d79 Got rid of startup functions and filters_postconfig(). 
By the way, how do you expect pointers to fit in an int?

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

printing community lists.

ac7a2145cc f_new_dynamic_attr gets third argument, type as filters know it. 2000-04-12 14:02:04 +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.

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.

77de68825c BGP_PATH masks now actually work as data type. 2000-04-12 12:10:37 +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.

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.

30a6108ccc Added filter_same() for comparision of two filters. 
Pavel, please implement this as soon as possible.

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.

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.

d3dd620b96 Filters: permit variables of prefix types, cleanup around 
variables. TODO list added, hopefully complete. Use new features of
filters in bird.conf

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.)

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.

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.
