-TODO
-====
-
-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.
-
-Feel free to contribute if you have the ability and free time - all the
-help is really appreciated - and needed.

-New features TODO
-=================
-
- 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 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 boolean (or bool), typedef of unsigned char.
-
- 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.
-
- 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.
-
- 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.
-
- 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
-===========================
+TODO/bugs 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
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.
+ This is not a showstopper.
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).
+TODO/bugs In SILC Server
+========================
- o Connection Authentication request resolving is missing and must be
- done. This is required by the protocol.
+ 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.
-
-TODO In SILC Server
-===================
-
- o TODO in command.c and in command_reply.c:
-
- o RESTART is not implemented
- o INVITE is probably not working correctly
- o JOIN does not check the invite and ban lists
- 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. Also, setting ban and invite lists does not
- work at all and requires some thinking how to do them.
- 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 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 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 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 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 Server says that it is able to listen on multiple ports but currently
that is bogus. It can, but internals are for single server.
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.
+ 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.
-
- 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 ID Cache expiry does not work.
+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 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.
-
+ 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

+ more (silcpkcs.h).
-Other Things TODO
-=================
- o Write manuals for server.
+TODO in the protocol before SILC 0.x
+====================================
- o Write manuals for client.
+ o New commands and features in the commands
+ (draft-riikonen-silc-spec-xx.txt):
- 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.
+ 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).
