f75e3bbc01 Fixed a couple of nasty CLI bugs which were triggered on long or multi-part
outputs. It took a whole evening to hunt them down, but now the CLI seems
to work fine.

Now I run three BGP connections with several thousand routes!

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.

56a2bed46b Don't import/export MED and LOCAL_PREF on external links.
Added real comparison of BGP routes (inspired by the Cisco one).
Default local preference and default MED are now settable.
Defined filter keywords for all BGP attributes we know.

700bbe60fb The previous fix for spacing was (a) totally out of context, (b) wrong.
Please *read* the code when trying to change it.

Also killed a couple of type clashes.

d3feceff10 BGP doesn't need any inline attributes. 2000-04-09 22:04:12 +00:00
Martin Mares
3991d84e8f Changed initialization of protocol list -- now we call proto_build() instead
of calling the protocols manually.

Implemented printing of dynamic attributes in `show route all'.

Each protocol can now register its own attribute class (protocol->attr_class,
set to EAP_xxx) and also a callback for naming and formatting of attributes.
The callback can return one of the following results:

	GA_UNKNOWN	Attribute not recognized.
	GA_NAME		Attribute name recognized and put to the buffer,
			generic code should format the value.
	GA_FULL		Both attribute name and value put to the buffer.

Please update protocols generating dynamic attributes to provide
the attr_class and formatting hook.

cfd46ee4c5 Added debugging of communication between protocols and routing tables.
Just ask for "debug routes" if you want to see the routes and "debug filters"
if you want even the rejected ones.
2000-03-12 20:30:53 +00:00
Martin Mares
839380d7ec Added debugging of protocol state transitions. 2000-03-07 21:50:21 +00:00
Martin Mares
f30b86f9d5 Added configuration of default protocol debugging flags. 2000-03-07 21:50:03 +00:00
Martin Mares
96d8e3bff2 Added protocol debugging flags (protocol.h: D_xxx), parsing of them
in configuration files and commands for manipulating them.

Current debug message policy:

   o  D_STATES, D_ROUTES and D_FILTERS are handled in generic code.
   o  Other debug flags should be handled in the protocols and whenever
      the flag is set, the corresponding messages should be printed
      using calls to log(L_TRACE, ...), each message prefixed with
      the name of the protocol instance. These messages should cover
      the whole normal operation of the protocol and should be useful
      for an administrator trying to understand what does the protocol
      behave on his network or who is attempting to diagnose network
      problems. If your messages don't fit to the categories I've defined,
      feel free to add your own ones (by adding them to protocol.h
      and on two places in nest/config.Y), but please try to keep the
      categories as general as possible (i.e., not tied to your protocol).
   o  Internal debug messages not interesting even to an experienced
      user should be printed by calling DBG() which is either void or
      a call to debug() depending on setting of the LOCAL_DEBUG symbol
      at the top of your source.
   o  Dump functions (proto->dump etc.) should call debug() to print
      their messages.
   o  If you are doing any internal consistency checks, use ASSERT
      or bug().
   o  Nobody shall ever call printf() or any other stdio functions.

Also please try to log any protocol errors you encounter and tag them
with the appropriate message category (usually L_REMOTE or L_AUTH). Always
carefully check contents of any message field you receive and verify all
IP addresses you work with (by calling ipa_classify() or by using the
neighbour cache if you want to check direct connectedness as well).

4c1b4e1a58 If the user has specified identical preferences for instances of different
protocols, break the tie by comparing addresses, so we keep the ordering
unambiguous.
2000-03-01 11:48:11 +00:00
Martin Mares
6a636392d3 Rewrote interface type detection logic. The `unnumbered' flag is now per
address, not per interface (hence it's ifa->flags & IA_UNNUMBERED) and
should be set reliably. IF_MULTIACCESS should be fixed now, but it isn't
wise to rely on it on interfaces configured with /30 prefix.

Manual disable/enable/restart/shutdown/reconfiguration of protocols
no longer hangs on loops in neighbor lists :)
2000-01-19 11:52:32 +00:00
Martin Mares
3ea1ba632b Killed protocol->priority. Protocol startup should be clean and hack-free now.
It seems everything still works (except for disable/enable/restart which hangs
sometimes, but it's another story).
2000-01-18 11:01:03 +00:00

471cc0be65 Moved initlialization of protocol lists to global init. Argh. 2000-01-17 12:38:07 +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.

88dc89f991 Device protocol supports reconfiguration. 2000-01-17 00:20:17 +00:00
Martin Mares
26368f656c Don't forget changing proto->name to point to name in new configuration
(to avoid the name being freed with the old config).

Also remember to add proto_pipe to protocol_list.
2000-01-17 00:19:58 +00:00
Martin Mares
f14a4becbe Reworked proto lists -- each proto is now in two lists: the global one
(proto_list) and per-type one (original lists). A lot of things simplified.

Implemented `disable', `enable' and `restart' CLI commands.
2000-01-16 23:30:06 +00:00
Martin Mares
30a6108ccc Added filter_same() for comparision of two filters.

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

ccdc339756 Avoid touching F_MODIFY, it no longer exists. 1999-12-16 12:59:09 +00:00
Martin Mares
f545d38707 Added universal locking mechanism which will solve problems
with protocols wanting to use the same port on the same interface
during reconfiguration time.

How to use locks: In the if_notify hook, just order locks for the
interfaces you want to work with and do the real socket opening after the
lock hook function gets called. When you stop using the socket, close
it and rfree() the lock.

Please update your protocols to use the new locking mechanism.

02c1fbddd4 Added proto_get_named() to be used in CLI commands to get protocol instance
of a given protocol with optionally given name. See `show static' for an
example.
1999-12-03 11:40:45 +00:00

Please implement them.
1999-12-01 15:08:32 +00:00
Martin Mares
f611f0ee82 Reset temporary parser data before parsing, not afterwards. This enables
deferred CLI command handlers to store their temporary data in the CLI
parsing pool.
1999-12-01 15:07:56 +00:00
Martin Mares
9685deb910 `show protocols' now shows time of last state change and protocol-dependent
status information (obtained via newly introduced hook protocol->get_status).
1999-12-01 12:00:15 +00:00

774f149959 Fix timeouts. Triggered updates are not done, yet. 1999-11-25 12:01:45 +00:00
Martin Mares
8d24b6899d Allow EA type to be set to 'undefined' which overrides all further definitons
of that EA in the same list and causes ea_find() to fail unless you add
EA_ALLOW_UNDEF to the second argument.

ea_sort (resp. ea_do_prune()) removes all undef'd attributes from the list.

I hope this works :)
1999-11-18 14:41:29 +00:00

da40b6f753 DEF_PREF_UKR and DEF_PREF_SINK removed. 1999-11-18 13:42:51 +00:00
Martin Mares
62a4639548 Added some temporary examples of how to define CLI commands (search for CF_CLI).
To define a new command, just add a new rule to the gramar:
  CF_CLI(COMMAND NAME, arguments, help-args, help-text) {
	what-should-the-command-do
	} ;
where <arguments> are appended to the RHS of the rule, <help-args> is the
argument list as shown in the help and <help-text> is description of the
command for the help.

<what-should-the-command-do> is a C code snippet to be executed. It should
not take too much time to execute. If you want to print out a lot of
information, you can schedule a routine to be called after the current
buffer is flushed by making cli->cont point to the routine (see the
TEST LONG command definition for an example); if the connection is closed
in the meantime, cli->cleanup gets called.

You can access `struct cli' belonging to the connection you're currently
servicing as this_cli, but only during parse time, not from routines scheduled
for deferred execution.

Functions to call inside command handlers:
  cli_printf(cli, code, printf-args) -- print text to CLI connection,
	<code> is message code as assigned in doc/reply_codes or a negative
	one if it's a continuation line.
  cli_msg(code, printf-args) -- the same for this_cli.

Use 'sock -x bird.ctl' for connecting to the CLI until a client is written.

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.
