TODO/bugs in Irssi SILC client ============================== o Do not let irssi update the status bar on JOIN until the join command is successful, so that it does not update that I'm on the channel even though I could not join the channel. o The CMODE notify handling in client library may return NULL client entry pointer to the application (when server was the CMODE's executor). Fix this somehow. o Add PERL scripting support from Irssi CVS. 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. Something like LISTKEYS, SHOWKEY... 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 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 Set different kind of settings, like, /set mutual_authentication, /set key_exchange_timeout, /set conn_auth_timeout etc etc. TODO/bugs In SILC Client Library ================================ o Library should save the cumode and not start from 0 everytime then CUMODE is issued. o Add some silc_client_del_client and other deletion funtions for application to delete client entrys from the cache. o All protocol execution timeouts are hard coded. They should be configurable and the Irssi SILC client should be able to set them with for example /set key_exchange_timeout etc. The silc_client_alloc should take a Params structure or something as argument. o silc_client_close_connection leaks memory. Read the XXX from code. o Some of the ops->say's should be removed and moved to the application from the library. Go through these. o The client library must manage somehow when receiving client that has same nickname, same server, same username but different Client ID than what we have in the cache. It is now assumed that they are different client but it might not be. It should at least number the clients using the client->num so that they can be accessed from the user interface separately or it could just remove the old client unless it is on some channels. 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. TODO/bugs In SILC Server ======================== 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: 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. o The backup router support described in the protocol specification should be done at some point. o New configuration file format must be added. The new one will be done using the dotconf config library (lib/dotconf). The following tasks relates closely to this as well and must be done at the same time when adding the new config file format: o Server says that it is able to listen on multiple ports but currently that is bogus. It can, but internals are for single server. o Protocol execution timeouts are hard coded, should be configurable. 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 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 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. 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 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. TODO In SILC Protocol ===================== o pp-03 draft: o Add SILC_MESSAGE_FLAG_SIGNED flag that indicates that the messages is signed with the senders private key and thus can be verified with its public key. This is especially handy feature when sending privat messages without having negotiated private keys, thus the servers decrypts and re-ecnrypts the messages. Other applications exists as well. o If channel founder mode is set and the invite mode is set on channel then the founder should be added to the list automatically so that if the founder signoff's it will be able join again to the invite only channel wihtout being invited. 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. 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 X.509 certificate support. SILC protocol supports certificates and it would be great to have support for them. This is a big task as support has to be made for ASN.1 as well. I've looked into OpenSSL package as it has X.509 certificate support (and ASN.1 as well). The code does not look very good to my eye but it has some potentials. This should be looked at more closely. Naturally own SILC Certificate API has to be defined regardles what the actual X.509 library is (OpenSSL X.509 or something else). Other choice is to write own X.509 library but I'm not going to do it - I can help to migrate the OpenSSL X.509 into SILC and I can help if someone would like to write the X.509 library - but I'm not going to start writing one myself. Anyhow, the OpenSSL X.509 lib should be checked. 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 Cipher optimizations (asm, that this) at least for i386 would be nice.
