Documentation
~~~~~~~~~~~~~
- write doctool
- write documentation :|

Globals
~~~~~~~
- right usage of DBG vs. debug
- logging and tracing; use appropriate log levels
- check incoming packets and log errors!!
- check log calls for trailing newlines and log levels followed by comma
- check if all protocols set proper packet priorities and TTL's.
- try compiling with -Wunused
- does everybody test return value of sk_open?
- doc: references to RFC's we did follow
- protocols: implement CLI hooks and per-procotol CLI commands
- protocols: implement reconfigure hook
- protocols: use locking
- check use of system includes and sprintf()

Various ideas
~~~~~~~~~~~~~
- static: allow specifying a per-route filter program for setting route attributes?
- netlink: realms
- netlink: import Linux route attributes to our rta's, so that they can be filtered?
- config: executable config files
- client: access control
- io: use poll if available
- IPv6 router advertisements
- real multipath (doesn't seem to be simple at all :()
- fake multipath (even less simple)
- route recalculation timing and flap dampening [see RFC2439 for algorithms]
- aggregate engine: standard route aggregation and summarization [RFC2519]
- aggregate engine: injection of manually configured pseudo-static routes
- generate default route if any working BGP connection exists (aggregate engine again?)
- generate default route to IGP's (aggregate engine yet another time?)
- look at RFC 2386 (QoS-based routing)

First look at data structures. More to come tomorrow... 1998-04-22 20:58:34 +08:00			`Core`

Updated TODO. 2000-05-08 22:18:33 +08:00			`- configure: default CFLAGS?`
Pruned the TODO list. 1999-08-04 03:35:01 +08:00
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 attribute list and all protocol specific rte attributes are contained there as temporary ones. Updated RIP to do that. Added ea_append() which joins two ea_list's. 2000-05-07 06:57:39 +08:00			`- filters: deletion of mandatory attributes?`
Implemented `show route <...> stats'. 2000-05-07 19:28:59 +08:00			`- filters: user defined attributes?`
bgp_get_status: If protocol is down, don't print BGP state. 2000-05-15 20:19:28 +08:00			`- filters: arithmetics and define'd symbols`
Implemented `show route <...> stats'. 2000-05-07 19:28:59 +08:00
Got rid of startup functions and filters_postconfig(). By the way, how do you expect pointers to fit in an int? 2000-05-15 18:53:56 +08:00			`- kernel: persistent mode`

Implemented `show route <...> stats'. 2000-05-07 19:28:59 +08:00			`- cli: show tables?`

Don't crash when the socket gets closed between updates. Also, this time not only update `remains', but update it right :) 2000-05-08 22:53:22 +08:00			`- table: ocassional core dumps in rt_prune()`
Generated first public alpha release. Unless you object, I'll announce it today (9.5.) at noon. 2000-05-09 06:37:16 +08:00			`- table: do feeding by parts`

Update `remains' counter correctly. 2000-05-08 22:32:19 +08:00			- proto: Don't show repeated `Changed state to ...' messages if only internal states change

Minor cleanups. 1999-12-16 21:51:43 +08:00			`Documentation`

Added skeleton of command tree. Please inspect. 1999-11-17 22:58:21 +08:00
Split off general commands to cmds.c. Added `show symbols' command which dumps whole symbol table together with symbol types etc. 2000-01-19 20:30:19 +08:00			`Globals`
Cleaned up TODO file. That's all for today, midnight gets closer. 1999-02-14 06:13:04 +08:00			`~~~~~~~`
			`- right usage of DBG vs. debug`
			`- logging and tracing; use appropriate log levels`
			`- check incoming packets and log errors!!`
Cleaned up debugging in kernel syncer. Netlink has still LOCAL_DEBUG turned on, but after some testing I'll gag it. 2000-03-13 05:54:39 +08:00			`- check log calls for trailing newlines and log levels followed by comma`
Cleaned up TODO file. That's all for today, midnight gets closer. 1999-02-14 06:13:04 +08:00			`- check if all protocols set proper packet priorities and TTL's.`
Implemented netlink protocol parsing functions. More to come tomorrow. 1999-03-02 06:31:27 +08:00			`- try compiling with -Wunused`
Fixed a couple of bugs in handling of multicast sockets. See comments in lib/socket.h for a detailed guide on how to use them. 1999-04-12 22:57:46 +08:00			`- does everybody test return value of sk_open?`

			`- protocols: implement CLI hooks and per-procotol CLI commands`
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 19:52:50 +08:00			`- protocols: implement reconfigure hook`
TODO entries and FIXME's. 1999-12-16 20:18:33 +08:00			`- protocols: use locking`
Use bsprintf() instead of sprintf(). 2000-04-01 07:33:03 +08:00			`- check use of system includes and sprintf()`

Reimplemented neighbor cache. Now uses real hashing. 2000-03-01 22:51:47 +08:00			`- netlink: import Linux route attributes to our rta's, so that they can be filtered?`
Made `datetime' more user friendly. Now it should be a quoted string of type "dd-mm-yyyy". 2000-03-01 19:42:13 +08:00			`- config: executable config files`
Support expansion of command abbreviations. Client considered finished (modulo bugs). 2000-02-28 06:00:19 +08:00			`- client: access control`

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. 1999-08-04 03:36:06 +08:00			`- aggregate engine: standard route aggregation and summarization [RFC2519]`

Tried to clean up multicast handling. Now we don't try to guess multicast abilities depending on definedness of symbols and use hard-wired system-dependent configuration defines instead. Please test whereever you can. 1999-12-16 21:06:13 +08:00			`- refuse running on non-multicast devices`
