TODO/bugs in Irssi SILC client
==============================
- o LEAVE does not work correctly, it doesn't leave the channel for real!
+ 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 /KICK does not remove the client from Irssi's NAMES list.
-
- 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
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.
- 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 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.
+ o When changing own nickname and there exists a same nickname the library
+ can give the client now nickname in format nick@host. This is new
+ behaviour and maybe should be removed. The changer should always
+ get the one it wants and not have the formatted nickname.
TODO/bugs In SILC Server
========================
- o Seems that router does not announce its client to the connecting
- server when server announces its clients on the channel.
-
- 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 If auto-reconnecting to router and EOF is received during the
+ connecting phase the server will not try to auto-reconnect anymore
+ after that. Fix to auto-reconnect.
- 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 Backup router related issues
- 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 Channel user mode changes are notified unnecessarely when
+ switching to backup router on router crash.
- 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
- serverconfig.c. They can be defined but they are totally
- ignored currently. And they should be redefined also.
+ 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!
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 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 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.
+ o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
+ private and silc_sim_alloc should take necessary arguments.
-TODO In SILC Protocol
+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 Add "request parameters" or similar to the WHOIS command, which can
+ be used to request various parameters (something not returned by
+ standard WHOIS command) about clients (info that could be fetched
+ even from clients). Additional specification (or appendix) should
+ be done to define the payload and the parameters. It could be used
+ to make the WHOIS command support various search conditions as well.
+ This would be the way to extend the WHOIS command to support various
+ new features without always making the command incompatible to previous
+ version. To be included in protocol version 1.1.
+
+ o Re-define the Status Payload: it is now 16 bits, split it into two
+ 8 bits fields. First field includes status types from 0 - 9 and
+ 10 - n *if* it is not an list of errors. If it is list of errors then
+ the first field includes 1, 2 and/or 3, and the second field includes
+ the error status 10 - n. This way it is possible to send multiple
+ errors (list of errors) and we have a way to tell the receiver that
+ there will be other errors as well. The second field is used only
+ if there is list of errors. If normal status, or normal (single)
+ error status the second field is set to zero, and must be ignored.
+ Hence, the status works same way as now except for list of errors.
+ To be included in protocol version 1.1.
+
+ o Define that WHOIS and IDENTIFY commands must send list of errors
+ if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was
+ requested and was not found. Each unfound entry must cause an error
+ command reply to the sender. Also define that errors must be sent
+ *after* sending successfully found entries (this way receiver may
+ ignore them). To be included in protocol version 1.1.
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).
+
+ o Implement the defined SilcDH API. The definition is in
+ lib/silccrypt/silcdh.h.
- 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.
- 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.
+ Other package that should be checked is the NSS's X509 library,
+ which I like more over OpenSSL package.
+
+ o SSH2 public keys support.
+
+ o OpenPGP certificate support.
o Cipher optimizations (asm, that this) at least for i386 would be nice.
