+TODO/bugs in Irssi SILC client
+==============================

 
 

- 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 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/bugs In SILC Client Library
-================================
+ 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 The QUIT command should wait for servers disconnection (at least for
+   a while) before exiting the application.

 
 

- 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 The JOIN command's HELP is generated from Irssi IRCs JOIN help and
+   the syntax is not same in SILC.  This must be fixed.

 
 

- 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 With USERS command to a channel user is not joined the name of the
+   channel is printed as garbled.

 
 

- o Input line on UI is buggy.  Cursor movement etc bugs.  Too lazy to
-   fix it.
+ 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
 ========================
 
 
 
 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 Add perhaps /var/run/silcd.pid for PID information for the server.
+
+ o Add a timeout to handling incmoing 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 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 Incomplete IPv6 support:

 
 

- 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 silcd/serverid.c and its routines supports only IPv4.

 
 

- 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 The backup router support described in the protocol specification
+   should be done at some point.

 
 

- o Protocol execution timeouts are hard coded, should be configurable.
+ 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 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 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 Re-key in general is actually missing (from everywhere) and must be done.
+ o Some ./prepare problems with latest autoconf and automake.

    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 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.  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 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 the protocol before SILC 0.x
-====================================
+ 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 New commands and features in the commands
-   (draft-riikonen-silc-spec-xx.txt):

 
 

-       o Define GETKEY command to fetch the public key of a server
-         and/or a client in the SILC Network.
-       o Define SENDKEY command to send your public key to a client
-         in the network.  Sending to the server must not be done due
-         to various security reasons (the server must not trust the
-         public keys blindly without third party verification; that's
-         why SENDKEY is not for servers).
+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.
