2000-03-07Added protocol debugging flags (protocol.h: D_xxx), parsing of themMartin Mares
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).
2000-03-04Garbage collector events and counters are now per table and one dayMartin Mares
they can be made configurable if it turns out to be useful.
2000-02-18Completion works. Unfortunately, we have to access a couple of internalMartin Mares
symbols of libreadline :-(
2000-01-19Split off general commands to cmds.c.Martin Mares
Added `show symbols' command which dumps whole symbol table together with symbol types etc.
2000-01-17Separated `official protocol names' used in status dumps from name templatesMartin Mares
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.
2000-01-17Reworked proto lists -- each proto is now in two lists: the global oneMartin Mares
(proto_list) and per-type one (original lists). A lot of things simplified. Implemented `disable', `enable' and `restart' CLI commands.
1999-12-06Implemented echoing of log messages to CLI connections. Just try `echo all'.Martin Mares
1999-12-05Don't forget to send an OK reply after dumping debug information.Martin Mares
1999-12-05Added DEBUG commands.Martin Mares
Removed CLI tests, real commands now serve as much better examples.
1999-12-03Renamed SHOW PROTOCOLS VERBOSE to SHOW PROTOCOLS ALL to be consistentMartin Mares
with the other commands.
1999-12-02Implemented `show route where <condition>' command.Martin Mares
Pavel, please check my addition to filter/config.Y.
1999-12-01Added dumping of routing tables (`show route'). This includes filtering.Martin Mares
1999-11-30Use TIME_INFINITY for initialization of password entries insteadMartin Mares
of 2000000000 (BTW who wrote that???)
1999-11-30`show interfaces' and `show protocols' works.Martin Mares
1999-11-25Added few basic commands: show status, show interfaces [summary],Martin Mares
show protocols (incomplete).
1999-11-17Added some temporary examples of how to define CLI commands (search for CF_CLI).Martin Mares
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.
1999-11-15An example of how to define enums.Martin Mares
1999-10-31Parse CLI commands. We use the same parser as for configuration files (becauseMartin Mares
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.
1999-10-02Obvious bugs in authentication fixed.Pavel Machek
1999-08-03Basic support for IPv6. The system-dependent part doesn't work yet,Martin Mares
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.
1999-08-03Cleaned up handling of interface patterns:Martin Mares
o Parsing of interface patterns moved to generic code, introduced this_ipatt which works similarly to this_iface. o Interface patterns now support selection by both interface names and primary IP addresses. o Proto `direct' updated. o RIP updated as well, it also seems the memory corruption bug there is gone.
1999-05-31Added PASSIVE option to paswwords.Pavel Machek
1999-05-26Change format of passwords (less ;'s) and fix password.h to allowPavel Machek
multiple inclusions.
1999-05-26Skeleton for password handling, currently I only build structures andPavel Machek
do nothing more advanced for them
1999-05-17From now we support multiple tables. The master_table variable isMartin Mares
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.
1999-04-05Changed syntax of attaching filters to protocols to hopefully the finalMartin Mares
version: EXPORT <filter-spec> for outbound routes (i.e., those announced by BIRD to the rest of the world). IMPORT <filter-spec> for inbound routes (i.e., those imported by BIRD from the rest of the world). where <filter-spec> is one of: ALL pass all routes NONE drop all routes FILTER <name> use named filter FILTER { <filter> } use explicitly defined filter For all protocols, the default is IMPORT ALL, EXPORT NONE. This includes the kernel protocol, so that you need to add EXPORT ALL to get the previous configuration of kernel syncer (as usually, see doc/bird.conf.example for a bird.conf example :)).
1999-03-29After today's lengthy discussions about filter syntax, let's clean upMartin Mares
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 `}'.
1999-03-26Moved to a much more systematic way of configuring kernel protocols.Martin Mares
o Nothing is configured automatically. You _need_ to specify the kernel syncer in config file in order to get it started. o Syncing has been split to route syncer (protocol "Kernel") and interface syncer (protocol "Device"), device routes are generated by protocol "Direct" (now can exist in multiple instances, so that it will be possible to feed different device routes to different routing tables once multiple tables get supported). See doc/bird.conf.example for a living example of these shiny features.
1999-03-17Allow input and output filters (only accept/reject style as we didn't defineMartin Mares
modifying filters yet) to be attached to protocol instances.
1999-02-05Implemented new configuration/reconfiguration interface and defined protocolMartin Mares
state machines. Full explanation will follow soon.
1998-12-06Name cleanups as suggested by Pavel:Martin Mares
- 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.
1998-11-29Added configuration of the device internal protocol. This is primarilyMartin Mares
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.
1998-11-29Allow setting debug value and `disabled' flag in protocol definition.Martin Mares
1998-11-27Oops, forgot to remove a debugging kludge.Martin Mares
1998-11-27Trivial 15-line bison excercise: Implemented expressions includingMartin Mares
user-defined numeric symbols. Whenever possible, use `expr' instead of `NUM' to get full express ion power :-)
1998-11-27First attempt at protocol configuration (now done only for RIP).Martin Mares
1998-11-27Parser fragment for the core. Now handles only router ID setting.Martin Mares
