TODO/bugs in Irssi SILC client
==============================
- 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 Does not show ops and normal users on JOIN correctly, perhaps some
+ theme issue (Fix this to 0.8.x).
- o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
- Seems the passwords in the .silc/config has no effect.
-
- 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.
-
- o Set different kind of settings, like, /set mutual_authentication,
- /set key_exchange_timeout, /set conn_auth_timeout etc etc.
+ o /cumode for unknown nick does not give any error message (Fix this to
+ 1.0).
TODO/bugs In SILC Client Library
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.

TODO/bugs In SILC Server
========================
- o Add hashed passwords to silcd.conf file.
+ o Configuration file additions (Do this to 0.8.x):
+
+ 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 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 (Fix
+ this to 0.9).
- o Backup router related issues
+ o The router should check for validity of received notify packets from
+ routers (fix this to 0.9). Following NOTIFYs needs to be verified:
+
+ o JOIN (check that joining is allowed)
+ o SIGNOFF (maybe should check that notifier owns the client)
+ o KILLED (check that killling is allowed (Protocol TODO #13))
+
+ o Backup router related issues (Fix this to 1.0):
o Channel user mode changes are notified unnecessarely when
switching to backup router on router crash.
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 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

- o Protocol execution timeouts are hard coded, should be

-
- o IP address fields in configuration file should accept mask
- format as well, IP/MASK, and not just plain IP.
+ 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

-TODO After 1.0
-==============
-
-A rough list of stuff that is going to be done to SILC after 1.0 or at
-least could be done.
-
- o Implement the defined SilcDH API. The definition is in
- lib/silccrypt/silcdh.h.
-
- 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.
-
- 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.
-
- Other package that should be checked is the NSS's X509 library,
- which I like more over OpenSSL package.
-
- o SSH2 public keys support, allowing the use of SSH2 public keys in
- SILC.
-
- o OpenPGP certificate support, allowing the use of PGP public keys
- in SILC.
-
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Zip API must be
- defined.
-
- o Rewrite the lib/silcutil/silcprotocol.[ch] not to have [un]register
- functions, but to make it context based all the way. The alloc should
- take as argument the protocol type and its callback (not only
- final callback). It is not good that we have now global list of
- registered protocols.
-
- o Optimizations in Libraries
-
- o There is currently three (3) allocations per packet in the
- silc_packet_receive_process, which is used to process and
- dispatch all packets in the packet queue to the parser callback
- function. First allocation is for parse_ctx, second for the
- SilcPacketContext, and third for packet->buffer where the actual
- data is saved.
-
- The parse_ctx allocation can be removed by adding it as a
- structure to the SilcPacketContext. When the SilcPacketContext
- is allocated there is space for the parse context already.
-
- The silc_packet_context_alloc could have a free list of
- packet contexts. If free packet context is found from the list
- it is returned instead of allocating a new one. The library
- could at first allocate them and save them to the free list
- until enough contexts for smooth processing exists in the list.
- This would remove a big allocation since the structure is
- quite big, and even bigger if it would include the parse_ctx.
-
- The packet->buffer can be optimized too if the SilcBuffer
- interface would support free lists as well. Maybe such could
- be done in the same way as for SilcPacketContext. The
- silc_buffer_alloc would check free list before actually
- allocating new memory. Since the packets in the SILC protocol
- usually are about the same size (due to padding) it would be
- easy to find suitable size buffer from the free list very
- quickly.
-
- These naturally cause the overal memory consumption to grow
- but would take away many allocations that can be done several
- times in a second.
-
- o Move the actual file descriptor task callback (the callback that
- handles the incoming data, outgoing data etc, that is implemnted
- in server and client separately (silc_server_packet_process and
- silc_client_packet_proces)) to the low level socket connection
- handling routines, and create an interface where the application
- can register a callbacks for incoming data, outoing data and EOF
- receiving, which the library will call when necessary. This way
- we can move the data handling in one place.
-
- o Add silc_id_str2id to accept the destination buffer as argument
- and thus not require any memory allocation. Same will happen
- with silc_id_payload_* functions.
-
- o Optimizations in Server
-
- o Remove the big switch statement from the function
- silc_server_packet_parse_type and replace it with predefined
- table of function pointers where each of the slot in table
- represents the packet type value.
-
- Same could be done with notify packets which has big switch
- statement too. Same kind of table of notify callbacks could be
- done as well.
-
- o The parser callback in the server will add a timeout task for
- all packets. It will require registering and allocating a
- new task to the SilcSchedule. Maybe, at least, for server
- and router packets the parser would be called immediately
- instead of adding it to the scheduler with 0 timeout. It
- should be analyzed too how slow the task registering process
- actually is, and find out ways to optimize it.
-
- o Add SilcAsyncOperation to utility library.
-
- o Cipher optimizations (asm, that this) at least for i386 would be nice.
-
- 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.
+ 15. The LEAVE command reply should return the Channel ID of the channel
