-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.
+TODO General
+============
o We should replace all short, int, long, unsigned short, unsigned int,
unsigned long with some pre-defined datatypes that really are what
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
===========================
the SilcSocketConnection reference counter at all. 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...
-
- 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.
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.

TODO In SILC Server
o TODO in commands (command.c and command_reply.c):
o RESTART is not implemented
- 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.
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.
o SERVER_SIGNOFF notify type is not implemented
- o TODO in authentication protocol (protocol.c):
-
- o Public key authentication is missing in initiator side. It must
- be implemented by creating the authentication data.
-
- o TODO in general server (server.c)
-
- o SILC_PACKET_CONNECTION_AUTH_REQUEST packet type is not
- implemented.
-
- o silc_server_connect_to_router_second checks the authentication
- method to be used in the connection. However, if it does not
- find it it must resolve it from the responder by sending the
- SILC_PACKET_CONNECTION_AUTH_REQUEST packet.
-
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
o Connection classes should be actually implemented in serverconfig.c.
They can be defined but they are totally ignored currently.
- o Connection redirect, if server is full, is not implemented. I also
- don't know how to do it currently. Maybe it shouldn't be done at all.
-
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 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.
o Re-key in general is actually missing (from everywhere) and must be done.
- o ID Cache expiry does not work.
-
o Compression routines are missing. The protocol supports packet
compression thus it must be implemented. SILC Comp 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 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 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
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.
+TODO in the protocol before SILC 0.x
+====================================
-Other Things TODO
-=================
+ o New commands and features in the commands
+ (draft-riikonen-silc-spec-xx.txt):
- o Write manuals for server.
+ 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 Write manuals for client.
+ o New features in the KE/auth protocol
+ (draft-riikonen-silc-ke-auth-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 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.
