+TODO/bugs in Irssi SILC client
+==============================
+
+ o Add local command to switch the channel's private key when channel has
+ several private keys. Currently sending channel messages with many
+ keys is not possible because changing the key is not possible by the
+ user.
+
+ o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
+ Seems the passwords in the .silc/config has no effect.
o Add local commands to list the current server and client public keys
that the user has. And a local command to dump the contents of the
- public key to the screen.
+ public key to the screen. Something like LISTKEYS, SHOWKEY...
- o Add client library parameters or options that handle what kind of
- messages the library should print out (using `say' client operation,
- for example) and what is left for the application to print. The
- appliation could for example set that it handles all command printing
- but all error printing should be handled by the library, etc...
- This is not a showstopper.
+ o The JOIN command's HELP is generated from Irssi IRCs JOIN help and
+ the syntax is not same in SILC. This must be fixed. Most likely
+ we must forget the Irssi's JOIN command and mimic it to get our
+ required syntax for it too.
- o Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
- fix it.
+ o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
+ cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
+ file.
+ o Add PERL scripting support from Irssi CVS.
-TODO/bugs In SILC Server
-========================
+ o Extend the /HELP command to support sub commands or something. So
+ that user can say /help set mutual_authentication they would get
+ help of the mutual_authentication setting.
- o The SKE protocol in the server does not verify the remote hosts
- (the router's) public key at all. All public keys are accepted without
- verification - this obviously is not secure.
+ o Set different kind of settings, like, /set mutual_authentication,
+ /set key_exchange_timeout, /set conn_auth_timeout etc etc.
- o When server quits and all clients of that server are removed from all
- channels the channel keys are re-generated for all clients. This is
- a bug and should be done only once per channel after all clients of
- the server has been removed.
- o Incomplete IPv6 support:
+TODO/bugs In SILC Client Library
+================================
+
+ o JOIN command's argument handling is buggy. See the XXX in the code.
- o silc_server_get_users_on_channel does not support IPv6 based
- Client ID's.
- o silc_server_route_get and the route code in general supports
- only IPv4.
- o silcd/serverid.c and its routines supports only IPv4.
- o DNS/IP lookup blocks the server. This must be fixed. Check the
- resolver stuff (resolver(3), resolver(5)). Either we have to do the
- own resolver stuff (through scheduler, if possible without writing
- too much own stuff) or use threads.
+TODO/bugs In SILC Server
+========================
- o The backup router support described in the protocol specification
- should be done at some point.
+ o Implement the <founder auth> and founder privileges gaining to
+ the JOIN command. This will bypass invite-only mode as well for
+ the client who got the founder mode during JOIN.
+
+ o After backup resume protocol the TOPIC_SET was not handled correctly
+ by all (unknown Channel ID).
+
+ o Channel user mode changes are notified unnecessarely when switching
+ to backup router on router crash.
+
+ o Change the server to connect to another server from low ports (706)
+ and not from high ports. Currently we cannot do incoming connection
+ checking by remote port because the port is not fixed.
+
+ o Announcements are incomplete: channel topics are not announced,
+ user modes (UMODE) are not announced.
+
+ o If client's public key is saved in the server (and doing public key
+ authentication) then the hostname and the username information could
+ be taken from the public key. Should be a configuration option!
+
+ o Add a timeout to handling incoming JOIN commands. It should be
+ enforced that JOIN command is executed only once in a second or two
+ seconds. Now it is possible to accept n incoming JOIN commands
+ and process them without any timeouts. THis must be employed because
+ each JOIN command will create and distribute the new channel key
+ to everybody on the channel.
+
+ o Optimize the WHOIS and IDENTIFY commands to somehow check whether the
+ requested clients are on some channel that the server knows about. If
+ this is the case then the request is not needed to be forwarded to the
+ router. One specific optimization could be done with JOIN command.
+ If the previous command to the WHOIS and IDENTIFY commands are JOIN
+ command (from the client) it can be expected (though it must be
+ verified) that the client is resolving the users on the channel it just
+ joined. If server has done this once there is really no reason to
+ resolve it twice (from the router), it can reply directly back with
+ the information it knows. This is because the server would (will)
+ receive notifications from the router for users that are on a local
+ channel.
+
+ The same is with whowas command. Actually with all these commands
+ it should be checked also whether the requested information is local.
+ If it is, there is no reason to send it to the router, since the server
+ knows it best.
o New configuration file format must be added. The new one will be
done using the dotconf config library (lib/dotconf). The following
o IP address fields in configuration file should accept mask
format as well, IP/MASK, and not just plain IP.
- o Connection classes should be actually implemented in
+ o Connection classes should be actually implemented in
serverconfig.c. They can be defined but they are totally
ignored currently. And they should be redefined also.
TODO/bugs In SILC Libraries
===========================
- o Incomplete IPv6 support:
+ o See client library TODO/bugs
- o All network routines in lib/silcutil/silcnet.[ch] does not
- support IPv6.
- o silc_id_render supports only IPv4 based ID's in the file
- lib/silcutil/silcutil.c.
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Comp API must be
- defined. zlib package is already included into the lib dir (in CVS,
- not in distribution), but it is not used yet, and it requires some
- tweaking on the Makefiles (we want static lib not shared).
-
- o The CAST cipher is not compiled currently due to compilation errors;
- check those. Cast is in lib/silccrypt/cast.c.
+TODO/Bugs in native WIN32 support (libraries)
+=============================================
- o All payload parsing (decoding) functions should take unsigned char *
- and uint32 as data and data length as arguments. Now some of the
- routines do already that but most of the routines use SilcBuffer.
- The SilcBuffer ones should be removed since buf->data and buf->len
- is more convenient to use. However, the silc_buffer_[un]format
- routines support only SilcBuffer so they would require reallocation
- of SilcBuffer. Maybe support for raw data (and not just SilcBuffer)
- should be added silc_buffer_[un]format_? routines. These are currently
- only cosmetic changes but at some point must be done to make the
- payload interfaces consistent.
+ o silc_net_create_connection_async does not work the same way than on
+ Unix. Do it with threads on WIN32. The function works but is not
+ actually async currently.
TODO After 1.0
==============
- o Pthreads support. A lot of problems are solved with server (and with
- client as well) if we add pthread support. We can forget things such
- as non-blocking connecting etc, and we can do things such as DNS/IP
- lookups async. The server itself also benefits great deal from
- threads, especially from performance point of view.
+ o Compression routines are missing. The protocol supports packet
+ compression thus it must be implemented. SILC Zip API must be
+ defined. zlib package is already included into the lib dir (in CVS,
+ not in distribution), but it is not used yet, and it requires some
+ tweaking on the Makefiles (we want static lib not shared).
- But, this is not a small task and almost entire SILC Library has to
- be made re-entrant. Own API is probably added for the threads support
- to make changes in the future as painless as possible. So the API
- would have things like silc_mutex_lock, silc_mutex_unlock and
- friends...
+ o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
+ SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
+ in separately.
o X.509 certificate support. SILC protocol supports certificates and
it would be great to have support for them. This is a big task as
to start writing one myself. Anyhow, the OpenSSL X.509 lib should
be checked.
+ Other package that should be checked is the NSS's X509 library.
+
o SSH2 public keys support. Maybe - not really needed but could be
nice as SSH is widely used all over the place. SILC Protocol
supports SSH2 public keys.
+ o OpenPGP certificate support.
+
o Cipher optimizations (asm, that this) at least for i386 would be nice.
