Martin Mares cc590a11a7 Changed syntax of expressions. Each `expr' can be now either a numeric literal
or a symbol or parenthesised filter expression.
2000-05-15 12:15:18 +00:00
Martin Mares e3f2d5fce3 Cleanup of configuration.
o  Use `expr' instead of `NUM' and `ipa' instead of `IPA',
   so that defined symbols work everywhere.
o  `define' now accepts both numbers and IP addresses.
o  Renamed `ipa' in filters to `fipa'.

Pavel, please update filters to accept define'd symbols as well.
2000-05-15 11:48:23 +00:00
Martin Mares 3b1c523d79 Got rid of startup functions and filters_postconfig().
By the way, how do you expect pointers to fit in an int?
2000-05-15 10:53:56 +00:00
Martin Mares d3abfbc68d Added prefix_or_ipa. 2000-05-13 11:41:26 +00:00
Martin Mares 758458be05 Unified parsing of prefixes.
Had to rename `prefix' in filters to `fprefix'.
2000-05-13 11:17:49 +00:00
Martin Mares ab1129c1bd Added skeleton Doc files for the whole developer's documentation. 2000-05-05 17:17:42 +00:00
Martin Mares 6db8c5a63b pxlen works even in IPv6 mode. 2000-05-04 20:02:19 +00:00
Martin Mares a412f01ea8 Include CF_HDR section in keywords.h as well, so that protocol symbols
can be used in definition of ENUM's.
2000-04-28 15:12:03 +00:00
Martin Mares 2edb31b097 Split CF_HDR section to CF_HDR (only includes) and CF_DEFINES (defines,
C declarations etc.).
2000-04-28 15:11:10 +00:00
Martin Mares 8f6accb5bb Event handlers no longer return re-queue flag. Instead of using it, just
call ev_schedule() on the same handler which should work perfectly now.
2000-04-27 22:28:49 +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 c3edb89ec1 Path masks are needed for filters. 2000-04-12 12:49:53 +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 abf2be7d0c Add internal commands of the client to the command list. 2000-03-12 23:04:04 +00:00
Martin Mares 4327090276 Made `show status' show uptime and time of last reconfiguration. 2000-03-12 22:44:54 +00:00
Martin Mares 6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules,
several debug() calls converted to DBG().
2000-03-12 21:01:38 +00:00
Pavel Machek c8d5ffafb7 Fix <=, >=, != 2000-03-10 20:21:12 +00:00
Martin Mares f30b86f9d5 Added configuration of default protocol debugging flags. 2000-03-07 21:50:03 +00:00
Martin Mares 16c07e3d51 Removed bogus comment. 2000-03-04 21:27:57 +00:00
Martin Mares a58dad6238 Please *think* when defining operator priorities.
(-: num_of_parser_conflicts -= 42 :-)
2000-03-04 21:19:10 +00:00
Martin Mares aee539f241 Made `datetime' more user friendly. Now it should be a quoted string
of type "dd-mm-yyyy".
2000-03-01 11:42:13 +00:00
Martin Mares 2ca3d9a8fc Defined INVALID_TOKEN which is a token guaranteed to be never generated. 2000-03-01 11:30:16 +00:00
Martin Mares 0223d4fff1 Client: Online help works (Cisco style: just press `?' at the end of a line). 2000-02-17 22:00:13 +00:00
Martin Mares f50b9e48b9 Generate a list of all commands and their help texts for the client to use. 2000-01-19 14:37:56 +00:00
Martin Mares 4b87e256eb Split off general commands to cmds.c.
Added `show symbols' command which dumps whole symbol table together
with symbol types etc.
2000-01-19 12:30:19 +00:00
Martin Mares d272fe22dd Separated `official protocol names' used in status dumps from name templates
used for automatic generation of instance names.

	protocol->name is the official name
	protocol->template is the name template (usually "name%d"),
		should be all lowercase.

Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.
2000-01-17 11:52:50 +00:00
Martin Mares ca0edc5395 When a quoted string is encountered, don't forget to copy it to the
config pool before passing it to the parser.
2000-01-16 23:36:53 +00:00
Martin Mares bf8558bc9c Converted shutdown to a kind of reconfiguration, it's no more handled
as a exception in protocol state machines. Introduced a `shutdown'
CLI command. Killed few reconfiguration bugs.
2000-01-16 17:40:26 +00:00
Martin Mares 50fe90edf3 First attempt on dynamic reconfiguration. There are still lots of bugs
and problems to solve, but the hardest part works.
2000-01-16 16:44:50 +00:00
Martin Mares 4ab5331c63 Added type `g' for void (general) pointer. 1999-12-06 13:50:50 +00:00
Martin Mares 7c0cc76ed7 Moved initialization of protocol list to proto.c.
Added sysdep configuration hooks.
1999-12-06 13:44:45 +00:00
Martin Mares f2c6c80a24 I tried to turn on the YYERROR_VERBOSE switch, but bison is buggy as hell,
so it doesn't even compile. Turned it again off and added a comment on it.
1999-12-02 14:03:25 +00:00
Martin Mares efe51e3863 Avoid `default rule can be matched' warning in CLI state. 1999-12-02 12:04:39 +00:00
Martin Mares 730f2e2c8c Added dumping of routing tables (`show route'). This includes filtering. 1999-12-01 15:10:21 +00:00
Martin Mares 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.
1999-11-30 14:03:36 +00:00
Martin Mares 3579376927 cli_msg() moved to cli.h, so that it can be used outside the parser. 1999-11-25 15:34:51 +00:00
Martin Mares ffb59d243a Command line interface now works. 1999-11-17 12:00:21 +00:00
Martin Mares 944f008af7 Defined CF_ENUM. 1999-11-15 11:35:41 +00:00
Martin Mares cbc3183007 SYM_STAT is gone. 1999-11-15 11:34:51 +00:00
Pavel Machek f453665704 Enumerational types, defined keyword added. 1999-11-10 12:44:07 +00:00
Martin Mares df8b85e33f Silly bug. 1999-11-04 13:53:47 +00:00
Martin Mares c8f61a01ea Symbols are not scoped. 1999-11-04 13:51:52 +00:00
Pavel Machek e5005be2b4 You should not follow next two times. 1999-11-03 22:21:26 +00:00
Martin Mares 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.
1999-10-31 17:47:47 +00:00
Pavel Machek 41be4444f2 switch() { } done right. 1999-10-28 21:03:36 +00:00
Martin Mares 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.
1999-08-03 19:36:06 +00:00
Pavel Machek 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
Pavel Machek 9d79fec8dc Added notion of datetime 1999-05-26 14:24:32 +00:00
Martin Mares 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.
1999-05-17 20:14:52 +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 38506f71b0 Sets of integers now actually work. Sets of IP will work as soon as
compare function is ready.
1999-04-12 19:58:18 +00:00
Pavel Machek 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 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.
1999-04-05 20:06:02 +00:00
Pavel Machek ba92164871 Update of filters towards new interface. 1999-03-29 20:21:28 +00:00
Martin Mares 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 `}'.
1999-03-29 19:04:14 +00:00
Martin Mares 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.
1999-03-17 14:29:39 +00:00
Pavel Machek 1aa5cf1c61 Added '=' to operator list 1999-03-09 14:44:43 +00:00
Pavel Machek b700582445 Filters are now a tiny bit stronger (if is actually working ;-) 1999-03-08 20:30:06 +00:00
Pavel Machek 3d8ef0c9ef I just don't like files enclosed in <>. 1999-03-02 13:15:35 +00:00
Martin Mares 726141746b '#' comments in config files are equivalent to end of line, therefore
also to implicit ';'.
1999-02-13 21:34:33 +00:00
Martin Mares 4e9498cbb1 config->router_id works again. 1999-02-13 18:42:00 +00:00
Martin Mares 31b3e1bbf5 Implemented new configuration/reconfiguration interface and defined protocol
state machines. Full explanation will follow soon.
1999-02-05 21:37:34 +00:00
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.
1999-01-15 18:04:28 +00:00
Martin Mares e3a39a9ee7 Killed duplicate %type for expr. 1999-01-15 16:59:26 +00:00
Pavel Machek b9d70dc84e Filters, second try. This time they have their own directory. 1999-01-15 16:49:17 +00:00
Pavel Machek 489b6b5e00 #if 1 that creeped into cvs killed. 1999-01-15 16:13:51 +00:00
Pavel Machek 72380a3447 Filters added. They are unable to do anything interesting for now
(with exception of printing integers to screen), but they exist.
1999-01-15 14:41:51 +00:00
Martin Mares 49e7e5ee0b New makefiles. Includes support for out-of-source-tree builds. 1999-01-10 00:18:32 +00:00
Martin Mares 89d2355d3d Added new rule for prefix length / netmask. 1998-12-06 23:10:45 +00:00
Martin Mares 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.
1998-12-06 23:10:28 +00:00
Martin Mares 0846203e89 Fixed bug in CF_ADDTO. How it's possible it has ever worked? 1998-12-06 17:39:08 +00:00
Martin Mares 166b9c4912 Added rule "bool" for boolean switches. 1998-12-06 17:38:42 +00:00
Martin Mares 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.
1998-12-06 11:59:18 +00:00
Martin Mares 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.
1998-11-29 22:03:58 +00:00
Martin Mares 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.
1998-11-29 21:59:37 +00:00
Martin Mares 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 :-)
1998-11-27 21:32:45 +00:00
Martin Mares c74c0e3cdf First attempt at protocol configuration (now done only for RIP). 1998-11-27 21:09:57 +00:00
Martin Mares 8450be97d6 Added generator of default names. 1998-11-27 21:07:02 +00:00
Martin Mares 70591fa064 Compile and use the new configuration code by default. 1998-11-27 19:37:07 +00:00
Martin Mares f142750d34 Base of the parser. 1998-11-27 19:36:06 +00:00
Martin Mares 82fc7be7bb Lexical analyser. 1998-11-27 19:35:50 +00:00
Martin Mares fe7cec12e8 Replaced nest/confile.h by conf/conf.h, added a lot of new definitions. 1998-11-27 19:35:10 +00:00
Martin Mares ce6ca80926 This script takes configuration fragments and generates full Bison grammar
from them.
1998-11-27 19:33:53 +00:00
Martin Mares 882c588a40 This script takes configuration fragments and extracts keyword list
from them.
1998-11-27 19:33:26 +00:00
