730f2e2c8c Added dumping of routing tables (`show route'). This includes filtering. 1999-12-01 15:10:21 +00:00

c9aae7f47f Lexer supports fallback symbol tables and uses them to recognize
symbols from global config when parsing CLI commands.

cf_lex_init_tables() is now called automatically inside the lexer.

bc2fb68098 Parse CLI commands. We use the same parser as for configuration files (because
we want to allow filter and similar complex constructs to be used in commands
and we should avoid code duplication), only with CLI_MARKER token prepended
before the whole input.

Defined macro CF_CLI(cmd, args, help) for defining CLI commands in .Y files.
The first argument specifies the command itself, the remaining two arguments
are copied to the help file (er, will be copied after the help file starts
to exist). This macro automatically creates a skeleton rule for the command,
you only need to append arguments as in:

	CF_CLI(STEAL MONEY, <$>, [[Steal <$> US dollars or equivalent in any other currency]]): NUM {
		cli_msg(0, "%d$ stolen", $3);
	} ;

Also don't forget to reset lexer state between inputs.

dce267832a Basic support for IPv6. The system-dependent part doesn't work yet,
but the core routines are there and seem to be working.

   o  lib/ipv6.[ch] written
   o  Lexical analyser recognizes IPv6 addresses and when in IPv6
      mode, treats pure IPv4 addresses as router IDs.
   o  Router ID must be configured manually on IPv6 systems.
   o  Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts.
   o  Fixed few places where ipa_(hton|ntoh) was called as a function
      returning converted address.

6542ece91a Function calling in filters works - somehow. Calling syntax is
currently very ugly, beware. Variables are not really local - that
needs to be fixed.

0e02abfd57 From now we support multiple tables. The master_table variable is
definitely gone. Both rte_update() and rte_discard() have an additional
argument telling which table should they modify.

Also, rte_update() no longer walks the whole protocol list -- each table
has a list of all protocols connected to this table and having the
rt_notify hook set. Each protocol can also freely decide (by calling
proto_add_announce_hook) to connect to any other table, but it will
be probably used only by the table-to-table protocol.

The default debugging dumps now include all routing tables and also
all their connections.

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.

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.

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
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'.
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.

(with exception of printing integers to screen), but they exist.

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.
