-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.

TODO General
============
datatype should be defined.
-TODO In SILC Client Library
-===========================
-
- o TODO in commands (silc/local_command.c, lib/silcclient/command.c and
- silc/silclient/command_reply.c):
-
- o Local command to handle private message keys is not done
- o Local command to handle channel private keys is not done
- o Local command to handle key agreement protocol is not done
- o RESTART command is not implemented
+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
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 Connection Authentication request resolving is missing and must be
- done. This is required by the protocol.
-
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.
+ This is not a showstopper.
o Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
fix it.
-TODO In SILC Server
-===================
-
- o TODO in commands (command.c and command_reply.c):
-
- 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):
-
- 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.
+TODO/bugs In SILC Server
+========================
- 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 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.
- 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.
-
- 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.
+ They can be defined but they are totally ignored currently. And they
+ should be redefined also.
-TODO In SILC Libraries
-======================
+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.
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
- 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
+ generation as the way it is done now sucks. Read from code for
+ more (silcpkcs.h).
TODO in the protocol before SILC 0.x
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 Define AWAY command to set the indication flag whether the
- client is present or not. Do not save the away message to the
- server though.
- o Define the channel founder property to be permanent locally in
- the server so that channel founder can regain its rights even
- if it disconnects from the server. Thus, define a new command
- or channel user mode that can be used to set the channel founder
- passphrase or public key that can be used in the authentication
- when regaining the founder rights.
-
- o New packets and features in the packets
- (draft-riikonen-silc-pp-xx.txt):
-
- o Define the Private Message packet to include private message
- flags and define the flags. The flags could indicate whether
- the message is, for example autoreply or the receiver should not
- reply to the private messages. What other flags?
- o Define the Channel Message packet to include channel message
- flags and define the flags. Actually the flags should be same
- as for the private message flags. This way we can implement
- for example the CTCP style ACTION (/ME command) messages.
-
- o New feature in the KE/auth protocol
- (draft-riikonen-silc-ke-auth-xx.txt):
-
- 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.
