TODO/bugs in Irssi SILC client
==============================
- o The input line parser in client (librarys) doesn't like extra spaces
- at the end of line (like after commands).
+ 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 Giving KILL command crashes the client.
-
- o Waiting the answer for accepting new key after the protocol has
- timeout and then ansering Y will crash the client.
-
- 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 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 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 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 Incomplete IPv6 support:
+ o Backup router related issues
- 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 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 The timeout calculation can go negative at least on BSD, so rewrite
- in in lib/silcutil/silcschdule.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 Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
+ private and silc_sim_alloc should take necessary arguments.
- 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.
+TODO in SILC Protocol
+=====================
+
+ 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 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 Implement the defined SilcDH API. The definition is in
+ lib/silccrypt/silcdh.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 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.
-
-
-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
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.
