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.

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.)

d4ff748224 Use a more reasonable pool chunk size: 4080 bytes seem to be a good 
approximation of a integral fraction of page size even if both malloc
overhead and chunk header space is counted.

7f400d1c62 After today's lengthy discussions about filter syntax, let's clean up 
whitespace/semicolon rules for whole config file:

   o  All non-zero amounts of whitespace are equivalent to single space
      (aka `all the whitespace has been born equal' ;-)).
   o  Comments count as whitespace.
   o  Whitespace has no syntactic signifance (it can only separate lexical
      elements).
   o  Consequence: line ends are no longer treated as `;'s.
   o  Every declaration must be terminated by an explicit `;' unless
      or by a group enclosed in `{' and `}'.

4ba84ebc82 Slightly better generator of default protocol instance names. 1999-03-26 21:37:29 +00:00

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.

726141746b '#' comments in config files are equivalent to end of line, therefore 
also to implicit ';'.

31b3e1bbf5 Implemented new configuration/reconfiguration interface and defined protocol 
state machines. Full explanation will follow soon.

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.

72380a3447 Filters added. They are unable to do anything interesting for now 
(with exception of printing integers to screen), but they exist.

cc12cf05c7 cf_error() now accepts any format strings instead of just an error 
message. Also added extra kludge to get rid of collisions of REJECT
symbols.

b35d72ac66 Name cleanups as suggested by Pavel: 
- cfg_strcpy() -> cfg_strdup()
- mempool -> linpool, mp_* -> lp_*  [to avoid confusion with memblock, mb_*]

Anyway, it might be better to stop ranting about names and do some *real* work.

50d8424ad1 Added configuration of the device internal protocol. This is primarily 
intended to serve as an example of interface pattern list use. As a side
effect, you can disable generating of device routes by disabling
this protocol.

49e4a4d1fd Created new functions for allocating configuration data: 
o  cfg_alloc(size) -- generic memory allocation
   o  cfg_allocu(size) -- unaligned memory allocation
   o  cfg_allocz(size) -- zeroed memory allocation
   o  cfg_strcpy(str) -- allocate a copy of a string

Also fixed a bug in lexing of string literals.

0b62c3a7c7 Trivial 15-line bison excercise: Implemented expressions including 
user-defined numeric symbols. Whenever possible, use `expr' instead
of `NUM' to get full express ion power :-)
