+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 JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
+ Seems the passwords in the .silc/config has no effect.
- - Pekka
+ 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...
+ 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.
-New features TODO
-=================
+ 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 Optimization in general. I have not focused to program optimized code
- in many circumstances. It has been more important to get this up and
- working. A lot must be optimized especially the ID cache. Instead of
- using lists some hash tables should be used. The searching by ID and
- such must be made a lot faster. If someone would like dedicate their
- efforts purely to generate optimized code I'd be appreaciated.
+ 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 Add boolean (or bool), typedef of unsigned char.
+ o Set different kind of settings, like, /set mutual_authentication,
+ /set key_exchange_timeout, /set conn_auth_timeout etc etc.
- o More platform supports should be added. The code is pretty much
- generic but there are some parts that require porting (SIM). Also,
- some support for different platforms is needed into configure.in.
- o SILC requires currently GCC to work because we use GCC specific
- compilation options. Generally any compiler that supports inline
- functions and can build shared libraries (for SIMs) should work.
- These cases should be included into configure.in.
+TODO/bugs In SILC Client Library
+================================
- o Extended SIM (SILC Module) support. Currently only SILC Cipher API
- and SILC Hash API may be used as SIM's. What I have in mind is to
- have extended support for SIM's so that basically any SILC API could
- be used as SIM's. This would open tremendous possiblities but
- opens also issues on security that needs to be dealt with.
+ o JOIN command's argument handling is buggy. See the XXX in the code.
- Some sort of SIM compilation environment should be defined so that
- the SIM's could use SILC specific symbols from the modules (which they
- cannot do currently). In the future modules could add new features
- to SILC easily with this support. I'm more thinking this from client's
- perspective to add new features to client (such as IRC support as SIM)
- but server should have the support as well. Anyhow, this is an
- interesting feature...
- This maybe post 1.0 task - dunno.
+TODO/bugs In SILC Server
+========================
- o SIM support for other platforms than just for Linux. Apache has
- example code (code that we could use directly pretty easily) for
- other platforms.
-
-TODO In SILC Client Library
-===========================
-
- 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.
-
- 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 Implement the <founder auth> and founder privileges gaining to
+ the JOIN command. This will bypass invite-only mode as well for
+ the client who got the founder mode during JOIN.
+ o Optimize the WHOIS and IDENTIFY commands to check if the request
+ includes an ID or multiple IDs, then they are checked from local cache
+ first, and not sent directly to router. This is because if they
+ are found in the local cache there's no need to send them to the
+ router. Only if some ID is not found, or an found entry is
+ incomplete it can be queried from the router. This way these
+ commands become faster, and for example JOIN command becomes a lot
+ faster since the server ends up resolving the same information only
+ once, as opposed to resolve it everytime JOIN command is issued, like
+ it does now.
-TODO In SILC Server
-===================
+ The same thing can be done with WHOWAS command as well.
- 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.
+ It is important to send these requests to router only if they can be
+ expanded to many results (as when doing WHOIS for nickname). If
+ they are explicit (like requesting by ID) the local cache MUST be
+ searched before sending it to router.
- o silc_server_send_key_agreement and silc_server_send_private_message_key
- are one and same function (also silc_server_send_private_message is
- almost same function). These should be unified to one generic named
- function and use that.
+ o Announcements are incomplete: channel topics are not announced,
+ user modes (UMODE) are not announced.
- 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 Change the server to connect to another server from low ports (706)
+ and not from high ports. Currently we cannot do incoming connection
+ checking by remote port because the port is not fixed.
- o Length of the packet processing timeouts needs to be checked whether
- they are too short or too long. I haven't really tested whether they
- are suitable. They should be tested on high load which I haven't done
- at all yet.
+ o Backup router related issues
- o INVITE command must set the channel's invite list if channel is
- invite-only channel.
+ o After backup resume protocol the TOPIC_SET was not handled
+ correctly by all (unknown Channel ID).
- 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 Channel user mode changes are notified unnecessarely when
+ switching to backup router on router crash.
- o Command flag usage in general is not implemented yet.
+ 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!
- o Client history must be implemented. Protocol says that server must
- keep history information about clients for some period of time.
+ 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 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 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 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.
-TODO In SILC Libraries
-======================
- 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.
+TODO/bugs In SILC Libraries
+===========================
- 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 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 Re-key in general is actually missing (from everywhere) and must be done.
- o ID Cache expiry does not work.
+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 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 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.
-
-
-Other Things TODO
-=================
-
- o Write manuals for server.
-
- o Write manuals for client.
-
- o Write SILC Library Reference manual. This would include all the SILC
- API's with simple examples how the functions are to be used. This is
- pretty easy to create by taking all the functions plus their comments
- from source/header files. However, same sort of reference manual
- should be written for client and server 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 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 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.
+ o OpenPGP certificate support.
+
o Cipher optimizations (asm, that this) at least for i386 would be nice.
