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 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 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 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. Something like LISTKEYS, SHOWKEY...
+ 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 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.
TODO/bugs In SILC Client Library
================================
- o Library should save the cumode and not start from 0 everytime then
- CUMODE is issued. A mechanism of getting the channel entry for
- CMODE and CUMODE by the command reply identifier must be added.
- Otherwise saving the modes for the channels and channel user
- entries are impossible since server does not send Channel ID as
- command reply in these functions.
+ o JOIN command's argument handling is buggy. See the XXX in the code.
- 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.
+TODO/bugs In SILC Server
+========================
- 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 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 Optimize the WHOIS and IDENTIFY commands to check if the request
+ includes an ID or multiple IDs, then they are checked from local cache
+ first, and not sent directly to router. This is because if they
+ are found in the local cache there's no need to send them to the
+ router. Only if some ID is not found, or an found entry is
+ incomplete it can be queried from the router. This way these
+ commands become faster, and for example JOIN command becomes a lot
+ faster since the server ends up resolving the same information only
+ once, as opposed to resolve it everytime JOIN command is issued, like
+ it does now.
-TODO/bugs In SILC Server
-========================
+ The same thing can be done with WHOWAS command as well.
+
+ It is important to send these requests to router only if they can be
+ expanded to many results (as when doing WHOIS for nickname). If
+ they are explicit (like requesting by ID) the local cache MUST be
+ searched before sending it to router.
+
+ o Announcements are incomplete: channel topics are not announced,
+ user modes (UMODE) are not announced.
+
+ 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 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 Backup router related issues
- o Incomplete IPv6 support:
+ o After backup resume protocol the TOPIC_SET was not handled
+ correctly by all (unknown Channel ID).
- 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 Channel user mode changes are notified unnecessarely when
+ switching to backup router on router crash.
- 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 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 The backup router support described in the protocol specification
- should be done at some point.
+ 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 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 WIN32 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.
- 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.
+
+TODO After 1.0
+==============
o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Comp API must be
+ 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).
- 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
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.
