+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 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.
-Feel free to contribute if you have the ability and free time - all the
-help is really appreciated - and needed.
+ 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...
- - Pekka
+ 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.
-TODO General
-============
+ 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 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 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.
-TODO In SILC Client Library
-===========================
-
- 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 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 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 Set different kind of settings, like, /set mutual_authentication,
+ /set key_exchange_timeout, /set conn_auth_timeout etc etc.
- o Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
- fix it.
+TODO/bugs In SILC Client Library
+================================
-TODO In SILC Server
-===================
+ 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 TODO in commands (command.c and command_reply.c):
+ o JOIN command's argument handling is buggy. See the XXX in the code.
- 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 TODO in notify types (packet_receive.c):
+TODO/bugs In SILC Server
+========================
- o SERVER_SIGNOFF notify type is not implemented
+ o Add perhaps /var/run/silcd.pid for PID information for the server.
- 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 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 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 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 Incomplete IPv6 support:
- 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 silcd/serverid.c and its routines supports only IPv4.
- 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.
+ 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.
-TODO In SILC Libraries
-======================
+ 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 The SKE Start Payload parsing routines are an overkill. Use the
- SILC_STR_UI16_NSTRING_ALLOC in the parsing and not parsing them
- one by one like done now.
- 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.
+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 Incomplete IPv6 support:
- 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 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 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 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
-====================================
+TODO/Bugs in native WIN32 support (libraries)
+=============================================
- o New commands and features in the commands
- (draft-riikonen-silc-spec-xx.txt):
+ 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.
- 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 New features in the KE/auth protocol
- (draft-riikonen-silc-ke-auth-xx.txt):
+TODO In SILC Protocol
+=====================
- o Define group exchange support for the SKE so that the SKE
- could be performed among more than two entities. This is not
- a showstopper and may be defined later.
+ 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 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.
+ 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.
