+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 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 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 When receiving client's public key with GETKEY or in key agreement
- protoocl it probably should be saved using the nickname and the real
- name of the client instead of the host name of the client.
+ o The QUIT command should wait for server's disconnection (at least for
+ a while) before exiting the application.
- 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.
+
+ 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 JOIN command's argument handling is buggy. See the XXX in the code.
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 On normal server the channel count can go negative (like -3 channels).
+
+ o Change the sever 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 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 JOIN command in normal server. When router returns
+ command reply for JOIN it returns the new channel key. We however
+ still create new channel key when processing the pending JOIN command.
+ This works ok but is not necessary.
- 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. This should be done so that
- is first checks denied connections, then client connections and then
- server connections. There is no use to execute the SKE if the connection
- will not be allowed.
+ 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.
- 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.
+ 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 The backup router support described in the protocol specification
- should be done at some point.
+ o Add support for sending the LIST command to primary router on normal
+ server to receive all the created channels. Currently the command
+ returns only the channels the server knows about. The protocol spec
+ does not prohibit of sending the LIST to the router.
- 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 Incomplete IPv6 support:
- o Protocol execution timeouts are hard coded, should be configurable.
+ o silcd/serverid.c and its routines supports only IPv4.
- o IP address fields in configuration file should accept mask format
- as well, IP/MASK, and not just plain IP.
+ o Add perhaps /var/run/silcd.pid for PID information for the server.
- 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.
+ 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 Security fixes from the latest draft for MAC key and MAC computation:
+ the packet sequence number.
+
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 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 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. These are currently only cosmetic changes
+ but at some point must be done to make the payload interfaces
+ consistent.
- o IPv6 support for ID's and into the code.
+ o Incomplete IPv6 support:
- o Some of the ciphers in lib/silccrypt does not implement the SILC
- Crypto API correctly.
+ 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 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 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 After 1.0
-==============
+TODO/Bugs in native WIN32 support (libraries)
+=============================================
- 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 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.
- 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...
+
+TODO In SILC Protocol
+=====================
+
+ 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 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.
