-TODO General
-============
+TODO/bugs in Irssi SILC client
+==============================
- o We should replace all short, int, long, unsigned short, unsigned int,
- unsigned long with some pre-defined datatypes that really are what
- we want on all platforms. int16, uint16, int32, uint32 etc. are
- what we could use or maybe SilcInt16, SilcUInt16 etc. Also, boolean
- datatype should be defined.
+ o LEAVE does not work correctly, it doesn't leave the channel for real!
+ o /KICK does not remove the client from Irssi's NAMES list.
-TODO In SILC Client Library
-===========================
+ 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.
+
+ o Add KNOCKOUT local command. It should kick an client from channel and
+ set a ban for it for number of seconds.
+
+ o Add KICKBAN local command. Kicks and bans the specified client.
+
+ o Do some /set show_mail_notification that would show a notification
+ on screen when new email is received.
+
+
+TODO/bugs In SILC Client Library
+================================
- o Client library crashes if for example server timeouts protocol
- execution and disconnects the client. The client, on the other hand
- may still assume that the connection is active, even after receiving
- the EOF. Reason for this is that the clien library does not handle
- the SilcSocketConnection reference counter at all. This must be
- fixed.
+ o If the silc_client_channel_message does not find the client entry
+ then it should attempt to resolve it at least once and no return
+ NULL entry to the application.
- o I guess, public key authentication (when connecting to a server)
- is not working currently. It is just matter of loading the keys
- from file and using them (see corresponding code in server).
+ 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,
but all error printing should be handled by the library, etc...
This is not a showstopper.
- o Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
- fix it.

-TODO In SILC Server
-===================
+TODO/bugs In SILC Server
+========================
- o TODO in commands (command.c and command_reply.c):
+ o Seems that router does not announce its client to the connecting
+ server when server announces its clients on the channel.
- o RESTART is not implemented
- o In servers all command reply funtions should still call the
- pending command reply even if the reply was error. In client
- it is not called but in server, I think, it must be called.
- When implementing this check that all commands handle the
- situation correctly when it is called as pending command
- (it should most likely check that cmd->pending == TRUE/FALSE).
+ 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 TODO in notify types (packet_receive.c):
+ o Incomplete IPv6 support:
- o SERVER_SIGNOFF notify type is not implemented
-
- o Acceptance of incoming connections (client and server connections)
- should be checked before key exchange protocol. Currently it is
- checked at the authentication phase after KE, that is ok, but it should
- be checked before starting KE, as well.
+ 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 Packet processing can be made faster. All packet function in the
- packet_receive.c has same prototypes. Instead of calling those from
- huge switch() make a table of callback functions that can be called
- directly by the packet type.
+ 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.

- They can be defined but they are totally ignored currently.

-TODO In SILC Libraries
-======================
+TODO/bugs In SILC Libraries
+===========================
+
+ o The timeout calculation can go negative at least on BSD, so rewrite
+ in in lib/silcutil/silcschdule.c.
- o Implement PFS (Perfect Forward Secrecy) flag in SKE (and in client and
- server, actually). If PFS is set, re-key must cause new key exchange.
- This is required by the SILC protocol.
+ o Incomplete IPv6 support:
- o Re-key in general is actually missing (from everywhere) and must be done.
+ 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
not in distribution), but it is not used yet, and it requires some
tweaking on the Makefiles (we want static lib not shared).
- o Rewrite the task system. I made it too complex and too "neat" and
- it really should be rewritten. We don't need priorities really, one
- priority is enough. This will simplify a lot the task system.
+ o The CAST cipher is not compiled currently due to compilation errors;
+ check those. Cast is in lib/silccrypt/cast.c.
- o SIM support for SILC PKCS API needs to made so that they could be
- used as SIM's. At the same time some work is required on prime
- generation as the way it is done now sucks. Read from code for
- more (silcpkcs.h).
+ 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 Random Number Generator needs some tweaking. Reading /dev/random may
- block resulting slow initialization of RNG. Some other things in the
- RNG may block as well. Also, I have some pending changes to the RNG
- that needs to be commited (from Schneier's Yarrow-160 paper). They
- should make the RNG even better.
+ 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 the protocol before SILC 0.x
-====================================
+TODO In SILC Protocol
+=====================
- o New commands and features in the commands
- (draft-riikonen-silc-spec-xx.txt):
+ o pp-03 draft:
- o Define GETKEY command to fetch the public key of a server
- and/or a client in the SILC Network.
- o Define SENDKEY command to send your public key to a client
- in the network. Sending to the server must not be done due
- to various security reasons (the server must not trust the
- public keys blindly without third party verification; that's
- why SENDKEY is not for servers).
+ 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.
