-TODO General
-============
+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 In SILC Client Library
-===========================
+ o The QUIT command should wait for server's disconnection (at least for
+ a while) before exiting the application.
+
+ 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 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 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 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).
+ o Add PERL scripting support from Irssi CVS.
- 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 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 Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
- fix it.
+ o Set different kind of settings, like, /set mutual_authentication,
+ /set key_exchange_timeout, /set conn_auth_timeout etc etc.
-TODO In SILC Server
-===================
+TODO/bugs In SILC Client Library
+================================
- o TODO in commands (command.c and command_reply.c):
+ o Someone changing nickname on the channel from nick to Nick will cause
+ that the new nick becomes Nick@host, because the old nick is not
+ removed from the cache before adding the new one. This is because
+ of the way NICK_CHANGE notify is handled. This should be fixed so
+ that if the old nick is to be removed the new nick will *replace*
+ the old one.
- o RESTART is not implemented
- 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 JOIN command's argument handling is buggy. See the XXX in the code.
- o TODO in notify types (packet_receive.c):
- o SERVER_SIGNOFF notify type is not implemented
+TODO/bugs In SILC Server
+========================
- 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 Add perhaps /var/run/silcd.pid for PID information for the 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 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 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 The backup router support described in the protocol specification
+ should be done at some point.
- 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 Incomplete IPv6 support:
- o Protocol execution timeouts are hard coded, should be configurable.
+ o silcd/serverid.c and its routines supports only IPv4.
- o IP address fields in configuration file should accept mask format
- as well, IP/MASK, and not just plain IP.
+ 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 Connection classes should be actually implemented in serverconfig.c.
- They can be defined but they are totally ignored currently.
+ 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 Protocol execution timeouts are hard coded, should be
+ configurable.
-TODO In SILC Libraries
-======================
+ o IP address fields in configuration file should accept mask
+ format as well, IP/MASK, and not just plain IP.
- 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 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 Re-key in general is actually missing (from everywhere) and must be done.
+
+TODO/bugs In SILC Libraries
+===========================
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 Incomplete IPv6 support:
- 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 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 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 the protocol before SILC 0.x
-====================================
- o New commands and features in the commands
- (draft-riikonen-silc-spec-xx.txt):
+TODO/Bugs in native WIN32 support (libraries)
+=============================================
- 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).
+ o 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.
-TODO After 1.0
-==============
+TODO In SILC Protocol
+=====================
- 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 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.
- 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...
+
+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.
