TODO/bugs in Irssi SILC client
==============================
- o Setting /away prints server/router operator modes as well.
- Print modes that was just set only.
+ o Fix the silc_channels_join to parse the command like, with fe.
+ silc_parse_command_line, because currently it ignores all options,
+ including passphrase which makes autojoin impossible to +a channels.
+ Other important options are ignored too.
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.
- o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
- Seems the passwords in the .silc/config has no effect.
+ o /cumode for unknown nick does not give any error message.
- 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 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 Add PERL scripting support from Irssi CVS.
-
- 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.
+TODO/bugs In SILC Client Library
+================================
- o Set different kind of settings, like, /set mutual_authentication,
- /set key_exchange_timeout, /set conn_auth_timeout etc etc.
+ o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
+ though). This should be added and perhaps new client operation
+ should be added to notify application that it was received and
+ set the key only if application wishes to set (accept the key) it.
+ o Additions to do after protocol version 1.1:
-TODO/bugs In SILC Client Library
-================================
+ o Fix the NICK_CHANGE notify handling not to create new entry
+ for the changed client, but take the nickname from the notify
+ (removes need for resolving as well). Protocol TODO entry 3.
- o N/A
+ o Add support for list of errors in command replies. Protocol
+ TODO entry 1.
TODO/bugs In SILC Server
========================
- o The LIST command reply should empty the global list because
- it is possible there stay channels that does not exist anymore.
- Empty it and put channels that server does not know about to
- global list.
+ o Configuration file additions:
- o Make the silc_server_command_pending_error_check function to
- take all arguments it received and put them to the reply it is
- sending. Otherwise for example WHOIS on normal server for bogus
- nickname does not print anything in the client.
+ o Add incoming connection frequency, incoming connection frequency
+ for single IP address, key exchange frequency, key exchange
+ frequency for single IP. Add also frequency base.
- o Backup router related issues
+ o Add hashed passwords to config file.
- o Channel user mode changes are notified unnecessarely when
- switching to backup router on router crash.
+ o Add rehashing support.
+
+ o If server send CUMODE_CHANGE notify (like setting founder) to router
+ and router does not have founder on channel (founder is left or there's
+ no founder on channel at all), the router will accept the server's
+ founder mode change, even though it perhaps should not do that.
+
+ o The router should check for validity of received notify packets from
+ servers (after all buggy servers may send notify that is actually
+ something that should have not been sent).
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
each JOIN command will create and distribute the new channel key
to everybody on the channel.
- 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 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 Protocol execution timeouts are hard coded, should be
- configurable.
+ o Backup router related issues
- o IP address fields in configuration file should accept mask
- format as well, IP/MASK, and not just plain IP.
+ o Channel user mode changes are notified unnecessarely when
+ switching to backup router on router crash.
- 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 Lots of statistics updating is missing around the server.
o If client's public key is saved in the server (and doing public key
authentication) then the hostname and the username information could
than on Unix. Do it with threads on WIN32. The function works but
is not actually async currently.
+ o EPOC specific additions/changes required:
+
+ o lib/silcutil/epoc routines missing or not completed.
+
+
+TODO in Toolkit Documentation
+=============================
+
+Stuff that needs to be done in order to complete the Tooolkit Reference
+Manual.
+
+ o ROBOdoc documenting missing from lib/silcutil/silcbuffer.h.
+
+ o ROBOdoc documenting missing from lib/silcutil/silcdlist.h.
+
+ o ROBOdoc documenting missing from lib/silcutil/silcfileutil.h.
+
+ o ROBOdoc documenting missing from lib/silcutil/silcutil.h.
+
+ o ROBOdoc documenting missing from lib/silccrypt/silchash.h.
+
+ o ROBOdoc documenting missing from lib/silccrypt/silccipher.h.
+
+ o ROBOdoc documenting missing from lib/silccrypt/silcpkcs.h.
+
+ o Write "Programming with Toolkit" document, describing how to build
+ Toolkit, how the build system works, where is everything, how
+ new (external) projects can be glued into Toolkit (use irssi as an
+ example), and how external projects can use Toolkit without gluing into
+ it (how to link etc), debugging, architecture, types, etc.
+
+ o Write "Platform Implementations" document to describe what platforms
+ Toolkit support, what has been implemented, what has not been, what
+ works differently etc.
+
+
+TODO in SILC Protocol
+=====================
-TODO After 1.0
-==============
+Current protocol version is 1.0. However, it is far from being perfect,
+and needs to include additional features. Following protocol TODO entries
+describe new stuff to be added to protocol versions 1.x.
- o Compression routines are missing. The protocol supports packet
- 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).
+ 1. Re-define the Status Payload: it is now 16 bits, split it into two
+ 8 bits fields. First field includes status types from 0 - 9 and
+ 10 - n *if* it is not an list of errors. If it is list of errors then
+ the first field includes 1, 2 and/or 3, and the second field includes
+ the error status 10 - n. This way it is possible to send multiple
+ errors (list of errors) and we have a way to tell the receiver that
+ there will be other errors as well. The second field is used only
+ if there is list of errors. If normal status, or normal (single)
+ error status the second field is set to zero, and must be ignored.
+ Hence, the status works same way as now except for list of errors.
+ To be included in protocol version 1.1.
- o Implement the defined SilcDH API. The definition is in
- lib/silccrypt/silcdh.h.
+ 2. Define that WHOIS and IDENTIFY commands must send list of errors
+ if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was
+ requested and was not found. Each unfound entry must cause an error
+ command reply to the sender. Also define that errors must be sent
+ *after* sending successfully found entries (this way receiver may
+ ignore them). To be included in protocol version 1.1.
- 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.
+ 3. Define the NICK_CHANGE notify to send the changed nickname as a new
+ third argument. This will make the NICK_CHANGE notify handling easier
+ in the receiver's end (client primarily) since it removes the
+ requirement that receiver must resolve (using IDENTIFY or WHOIS) the
+ new Client ID received in the notify (because of the new nickname is
+ unknown). To be included in protocol version 1.1.
- 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
- support has to be made for ASN.1 as well. I've looked into OpenSSL
- package as it has X.509 certificate support (and ASN.1 as well).
- The code does not look very good to my eye but it has some potentials.
- This should be looked at more closely.
+ 4. Add "request parameters" or similar to the WHOIS command, which can
+ be used to request various parameters (something not returned by
+ standard WHOIS command) about clients (info that could be fetched
+ even from clients). Additional specification (or appendix) should
+ be done to define the payload and the parameters. It could be used
+ to make the WHOIS command support various search conditions as well.
+ This would be the way to extend the WHOIS command to support various
+ new features without always making the command incompatible to previous
+ version. To be included in protocol version 1.1.
- Naturally own SILC Certificate API has to be defined regardles what
- the actual X.509 library is (OpenSSL X.509 or something else). Other
- choice is to write own X.509 library but I'm not going to do it -
- I can help to migrate the OpenSSL X.509 into SILC and I can help if
- someone would like to write the X.509 library - but I'm not going
- to start writing one myself. Anyhow, the OpenSSL X.509 lib should
- be checked.
+ 5. Inviting and banning by public key should be made possible. To be
+ included in protocol version 1.x.
- Other package that should be checked is the NSS's X509 library,
- which I like more over OpenSSL package.
+ 6. Add perhaps SILENCE_USERS, SILENCE_OPERS channel user modes which
+ can be used to silence (moderate) normal users and opers (this set
+ only by founder). To be included in protocol version 1.1.
- o SSH2 public keys support.
+ 7. Channel Message Payload needs slight redesining to include the IV
+ field to the MAC generation of the payload. It is authenticated
+ by the packet's MAC but not by the payload's MAC. Since the IV
+ belongs to the payload, its integrity should be protected by the
+ payload MAC and not alone by packet MAC. To be included in protocol
+ version 1.1.
- o OpenPGP certificate support.
+ 8. Remove the administrative commands from the protocol all together.
+ It does not make sense for the protocol to define how a server is
+ reconnected or shutdown, since they are implementation and
+ configuration issues. Besides protocol provides only limited set of
+ administrative commands and cannot define all that one could imagine.
+ To be included in protocol version 1.1.
- o Cipher optimizations (asm, that this) at least for i386 would be nice.
+ 9. Add SILC_MESAGE_FLAG_REPLY for being other side to the
+ SILC_MESSAGE_FLAG_REQUEST. Add generic SILC_MESSAGE_FLAG_DATA, which
+ can include generic payload, which can include generic data. The
+ payload definition is left out for now. To be included in protocol
+ version 1.1.
+
+ 10. Check command reply error status types in various commands,
+ specifically NO_FOPRIV is missing from many commands. To be
+ included in protocol version 1.1.
+
+ 11. Change the wording in Private Message Key Payload definition to
+ describe the problems of trusting the payload, and to indicate that
+ the receiver may not accept the key in the payload, and to describe
+ other means of distributing a key.
+
+ 13. Add the killer's client ID to the KILLED notify. To be included in
+ protocol version 1.1.
+
+ 14. The length of Arguments Num field in Notify Payload and Command
+ Payload enforces that total of 256 arguments can be associated
+ to a such payload. However, command-xx draft specified much higher
+ values, and these should be fixed.
