Internet on FIRE

Use `switch' for `disabled'.

Added read-only access to all required fields in rta.

Fixed incorrect error message about router ID syntax.

Added `show route for

' which looks up route leading to
given network.

Implemented `show route count' which is `show route stats' with
exception that it doesn't print the routes themselves.

Added commands `show route protocol <p>' and `show route import <p>' which
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an...

Split CF_HDR section to CF_HDR (only includes) and CF_DEFINES (defines,
C declarations etc.).

Added tracing of interface events.

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...

Completion works. Unfortunately, we have to access a couple of internal
symbols of libreadline :-(

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...

Implemented echoing of log messages to CLI connections. Just try `echo all'.

Added DEBUG commands.

Removed CLI tests, real commands now serve as much better examples.

Implemented `show route where <condition>' command.

Pavel, please check my addition to filter/config.Y.

Use TIME_INFINITY for initialization of password entries instead
of 2000000000 (BTW who wrote that???)

Added few basic commands: show status, show interfaces [summary],
show protocols (incomplete).

An example of how to define enums.

Obvious bugs in authentication fixed.

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....

Change format of passwords (less ;'s) and fix password.h to allow
multiple inclusions.

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...

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....

Allow input and output filters (only accept/reject style as we didn't define
modifying filters yet) to be attached to protocol instances.

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.

Allow setting debug value and `disabled' flag in protocol definition.

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 :-)

Parser fragment for the core. Now handles only router ID setting.
