CF_HDR
Implemented new configuration/reconfiguration interface and defined protocol state machines. Full explanation will follow soon.
1999-02-05 21:37:34 +00:00
static struct proto_config *this_proto;
Cleaned up handling of interface patterns: 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.
1999-08-03 19:30:49 +00:00
static struct iface_patt *this_ipatt;
First attempt at protocol configuration (now done only for RIP).
1998-11-27 21:09:57 +00:00
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

1998-11-27 19:37:57 +00:00
CF_DECLS
Moved to a much more systematic way of configuring kernel protocols. 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.
1999-03-26 21:44:38 +00:00
CF_KEYWORDS(ROUTER, ID, PROTOCOL, PREFERENCE, DISABLED, DEBUG, ALL, OFF, DIRECT)
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).
2000-03-07 20:49:48 +00:00
CF_KEYWORDS(INTERFACE, IMPORT, EXPORT, FILTER, NONE, TABLE, STATES, ROUTES, FILTERS)
Added tracing of interface events.

An example of how to define enums.
1999-11-15 11:36:22 +00:00
CF_ENUM(T_ENUM_RTS, RTS_, DUMMY, STATIC, INHERIT, DEVICE, STATIC_DEVICE, REDIRECT,
RIP, RIP_EXT, OSPF, OSPF_EXT, OSPF_IA, OSPF_BOUNDARY, BGP, PIPE)
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
%type <i32> idval
Changed syntax of attaching filters to protocols to hopefully the final 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 :)).
1999-04-05 20:15:31 +00:00
%type <f> imexport
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
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 `}'.

| INTERFACES { $$ = D_IFACES; }
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).

Cleaned up handling of interface patterns: 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.

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.
