+TODO/bugs in Irssi SILC client
+==============================
-This is more or less complete list of tasks that has to be done before
-SILC 1.0 could ever be released. It is clear that the list does not
-include all the bugs that exists. At the end of list are tasks that
-needs to be done but are probably post 1.0.
+ 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.
-Feel free to contribute if you have the ability and free time - all the
-help is really appreciated - and needed.
+ o The QUIT command should wait for servers disconnection (at least for
+ a while) before exiting the application.
- - Pekka
+ 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 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...
-TODO General
-============
+ o Add PERL scripting support from Irssi CVS.
- 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 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 In SILC Client Library
-===========================
-
- o TODO in commands (silc/local_command.c, lib/silcclient/command.c and
- silc/silclient/command_reply.c):
-
- o Local command to handle private message keys is not done
- o Local command to handle channel private keys is not done
- o Local command to handle key agreement protocol is not done
- o RESTART command is not implemented
-
- 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 Logic for handling multiple same nicknames for example in private
- message sending. I guess the logic is done in server side but is
- missing from client.
-
- 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, it should
- support public key authentication already).
-
- o Connection Authentication request resolving is missing and must be
- done. This is required by the protocol.
-
- 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...
-
- o Non-blocking connection on the background must be stopped if some
- other connection on same window has established. Now it is possible
- that some non-blocking connection timeouts on the background when
- we already have a working connection to some other place; things
- goes bad.
-
- o Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
- fix it.
-
-
-TODO In SILC Server
-===================
- o TODO in commands (command.c and command_reply.c):
+TODO/bugs In SILC Client Library
+================================
- o RESTART is not implemented
- o CMODE should be rewritten as it uses a lot duplicated code.
- Some of the modes may still not be implemented or is implemented
- the wrong way.
- 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 The public key authentication is missing for example in OPER and SILCOPER
+ commands. See the XXX's in the lib/silcclient/command.c.
- o TODO in notify types (packet_receive.c):
+ 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 SERVER_SIGNOFF notify type is not implemented
- o TODO in authentication protocol (protocol.c):
+TODO/bugs In SILC Server
+========================
- o Public key authentication is missing in initiator side. It must
- be implemented by creating the authentication data.
+ o Incomplete IPv6 support:
- o TODO in general server (server.c)
+ o silcd/serverid.c and its routines supports only IPv4.
- o SILC_PACKET_CONNECTION_AUTH_REQUEST packet type is not
- implemented.
+ o The backup router support described in the protocol specification
+ should be done at some point.
- o silc_server_connect_to_router_second checks the authentication
- method to be used in the connection. However, if it does not
- find it it must resolve it from the responder by sending the
- SILC_PACKET_CONNECTION_AUTH_REQUEST packet.
+ 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 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 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 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 Protocol execution timeouts are hard coded, should be
+ configurable.
- 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 IP address fields in configuration file should accept mask
+ format as well, IP/MASK, and not just plain IP.
- 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 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 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.
-
- o Connection redirect, if server is full, is not implemented. I also
- don't know how to do it currently. Maybe it shouldn't be done at all.
+TODO/bugs In SILC Libraries
+===========================
-TODO In SILC Libraries
-======================
+ o Move all utility stuff to undef lib/silcutil/. This includes trq,
+ dotconf and zlib.
- 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 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 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.
- 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 Scheduler needs to be analyzed on high load as it might be unfair
- towards select() because it may run timeout tasks before select() and
- after select(). If it is found to be unfair the timeout task running
- before select() should probably be removed.
+TODO/Bugs in native WIN32 support (libraries)
+=============================================
+ o silc_net_create_connection_async does not work the same way than on
+ Unix. Do it with threads on WIN32.
-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.
+TODO In SILC Protocol
+=====================
- 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 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.
