Core
~~~~
- socket open failure should not be fatal
- &&,||: priorities
- client: `?' in BGP masks
- filters: function for BGP path length
- static: allow specifying a per-route filter program for setting route attributes?

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?
- protocols: implement CLI hooks and per-procotol CLI commands
- protocols: implement reconfigure hook
- protocols: use locking
- check use of system includes and sprintf()
- refuse to run twice on single system


RPM
~~~
- build v4 and v6 in once

Various ideas
~~~~~~~~~~~~~
- client: paging of output
- client: Ctrl-R eats one more enter
- bgp: timing of updates?
- netlink: realms
- netlink: import Linux route attributes to our rta's, so that they can be filtered?
- config: executable config files
- filters: user defined attributes?
- 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)
- cli: show tables?

OSPF
~~~~
	- refuse running on non-multicast devices
	- importing of device routes for networks where we don't run OSPF
	- check incoming packets using neighbor cache
	- RFC2328 appendix E: Use a better algorithm
	- automatic generation of external route tags (RFC1403)
	- RFC1587 NSSA areas
	- RFC2370 opaque LSA's
	- respect interface MTU and try not to create larger packets unless unavoidable
        - AS external LSAs are in topology database of every OSPF Area
        - Limit export rate of external LSAs (like Gated does)
        - Maximal distance is just 0xffff, but 2328 requires 0xffffff
First look at data structures. More to come tomorrow... 1998-04-22 12:58:34 +00:00			`Core`

Use our own SUN_LEN if libc doesn't provide it. 2000-06-16 23:12:47 +00:00			`- socket open failure should not be fatal`
			`- &&,\|\|: priorities`
			- client: `?' in BGP masks
			`- filters: function for BGP path length`
If compiled with --enable-debug, don't even try to log to syslog unless the user forces it in the config file. 2000-06-19 23:50:02 +00:00			`- static: allow specifying a per-route filter program for setting route attributes?`
Added skeleton of command tree. Please inspect. 1999-11-17 14:58:21 +00:00
Split off general commands to cmds.c. Added `show symbols' command which dumps whole symbol table together with symbol types etc. 2000-01-19 12:30:19 +00:00			`Globals`
Cleaned up TODO file. That's all for today, midnight gets closer. 1999-02-13 22:13:04 +00:00			`~~~~~~~`

Cleaned up debugging in kernel syncer. Netlink has still LOCAL_DEBUG turned on, but after some testing I'll gag it. 2000-03-12 21:54:39 +00:00			`- check log calls for trailing newlines and log levels followed by comma`
Cleaned up TODO file. That's all for today, midnight gets closer. 1999-02-13 22:13:04 +00:00			`- check if all protocols set proper packet priorities and TTL's.`
Implemented netlink protocol parsing functions. More to come tomorrow. 1999-03-01 22:31:27 +00:00			`- 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 14:57:46 +00:00			`- does everybody test return value of sk_open?`

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 11:52:50 +00:00			`- protocols: implement reconfigure hook`
TODO entries and FIXME's. 1999-12-16 12:18:33 +00:00			`- protocols: use locking`
Use bsprintf() instead of sprintf(). 2000-03-31 23:33:03 +00:00			`- check use of system includes and sprintf()`
TODO updated. 2004-06-06 16:05:14 +00:00			`- refuse to run twice on single system`

Updated the TODO list with our last-minute stuff. Moved the rest to "Various ideas". 2000-06-04 20:06:42 +00:00			`- client: paging of output`
			`- client: Ctrl-R eats one more enter`
Asynchronous feeding of protocols. 2000-05-19 10:46:26 +00:00			`- bgp: timing of updates?`
Generated first public alpha release. Unless you object, I'll announce it today (9.5.) at noon. 2000-05-08 22:37:16 +00:00			`- netlink: realms`
Reimplemented neighbor cache. Now uses real hashing. 2000-03-01 14:51:47 +00:00			`- 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 11:42:13 +00:00			`- config: executable config files`
When in persist mode, don't delete routes from kernel tables even if they cease to exist in our routing tables due to protocols having shut down. 2000-05-16 13:36:38 +00:00			`- filters: user defined attributes?`
Support expansion of command abbreviations. Client considered finished (modulo bugs). 2000-02-27 22:00:19 +00:00			`- client: access control`

Pruned the TODO list. 1999-03-01 17:51:29 +00:00			`- route recalculation timing and flap dampening [see RFC2439 for algorithms]`
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			`- 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 13:06:13 +00:00			`- refuse running on non-multicast devices`
