+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 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 The QUIT command should wait for servers disconnection (at least for
+ a while) before exiting the application.
-New features TODO
-=================
+ 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.
- 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 With USERS command to a channel user is not joined the name of the
+ channel is printed as garbled.
- 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 Add boolean (or bool), typedef of unsigned char.
+ 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 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 Set different kind of settings, like, /set mutual_authentication,
+ /set key_exchange_timeout, /set conn_auth_timeout etc etc.
- 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.
+TODO/bugs In SILC Client Library
+================================
- 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...
+ o JOIN command's argument handling is buggy. See the XXX in the code.
- 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/bugs In SILC Server
+========================
-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 Private message key setting is missing and must be implemented.
- Currently private messages are encrypted with session keys. This
- is required by the protocol.
-
- o Channel private key setting is missing and must be implemented.
- Currently there cannot be private keys for channels. Normal channel
- keys (generated by server) are used. This is required by the protocol.
-
- 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 Move ssh_client_notify_by_server to its own file (like notify.[ch]).
-
- o Key Exchange protocol's responder side is missing from client.
- Generally it is possible for the client to be responder so it should
- be implemented (See corresponding code from server). Error handling
- in the KE protocol is also in pretty bad shape in client.
-
-
-TODO In SILC Server
-===================
-
- 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 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 INVITE command must set the channel's invite list if channel is
- invite-only channel.
-
- 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 Add perhaps /var/run/silcd.pid for PID information for the server.
- o Command flag usage in general is not implemented yet.
+ 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 Client history must be implemented. Protocol says that server must
- keep history information about clients for some period of time.
+ o Incomplete IPv6 support:
- o Protocol execution timeouts are hard coded, should be configurable.
+ o silcd/serverid.c and its routines supports only IPv4.
- o serverconfig.c and the function naming in it is inconsistent. It is
- not silc_config_server* it should be silc_server_config*. As should
- all the SilcConfigServer* types be SilcServerConfig*.
+ o The backup router support described in the protocol specification
+ should be done at some point.
- o Implement DENY_CONNECTION section in serverconfig.c and in server.
+ 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 Implement REDIRECT_CLIENT section in serverconfig.c and in server.
+ 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 Configuration file format - could be better.
+ 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.
+ 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.
+ 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 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 Statistics are totally missing from the server. It would be nice
- to gather some statistics.
-
-
-TODO 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 silc_id_str2id must also take ID length as argument. Otherwise, variable
- length ID's (after we add IPv6) will not work.
-
- o Re-key in general is actually missing (from everywhere) and must be done.
-
- o ID Cache expiry does not work.
-
- o PKCS#1 style RSA public key encryption/decryption/sign/verify is
- missing, and should be added for interoperability reasons. The thing
- I've done now is bad and should be removed as soon as possible (or
- the protocol should then state the method of how they should be done).
-
- 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 On select() issue; maybe we should use poll() instead if it is
- available? poll() doesn't have max fd limit...
+TODO/bugs In SILC Libraries
+===========================
- 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 Some ./prepare problems with latest autoconf and automake.
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 Cipher API needs to be made more consistent. Some parts of the
- code generated with current Cipher API looks really bad. Same
- is with PKCS API, even worse actually. They need to be made
- cleaner. Introducing silc_cipher_encrypt/decrypt/set_key etc.
- functions (I actually don't understand why have I left these un-done).
+ 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 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 Incomplete IPv6 support:
- o silc_buffer_[un]format() needs to be made more stable as it may
- crash the SILC if malformed data is sent as argument. There are a
- lot of places in client and server where we trust directly data coming
- from network and try to unformat it. The unformatting routine needs
- to be able handle situations where data sent is malformed, by mistake
- or intentionally. This is important as it is easy to crash the SILC
- now by just sending malformed data. Also, in client and server we
- must start checking the return value from silc_buffer_[un]format.
+ 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 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.
-Other Things TODO
-=================
- o Write manuals for server.
+TODO/Bugs in native WIN32 support (libraries)
+=============================================
- o Write manuals for client.
+ o silc_net_create_connection_async does not work the same way than on
+ Unix. Do it with threads on WIN32.
- 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 In SILC Protocol
+=====================
-TODO After 1.0
-==============
+ 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.
- 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...
+TODO After 1.0
+==============
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.
