TODO/bugs in Irssi SILC client
==============================
- o GETKEY server will save the serverkey to the same filename as the
- connected server and thus destroys the key.
-
- o GETKEY server will show first, "there is no such nickname".
+ 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 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.
TODO/bugs In SILC Client Library
================================
- o Remove the assert from silc_client_file_send.
-
- o Having @ in nickname will crash the client after changing the nickname
- back without the @.
-
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 should /nick nick and /nick Nick cause the Nick to be Nick@host becase
- it used to be nick??
-
- o When changing own nickname and there exists a same nickname the library
- can give the client now nickname in format nick@host. This is new
- behaviour and maybe should be removed. The changer should always
- get the one it wants and not have the formatted nickname.
-
- o Remove the command destructor all together from the client, it is
- not needed and its usage is buggy when the context is registered
- to multiple pending commands.
-
o Additions to do after protocol version 1.1:
o Fix the NICK_CHANGE notify handling not to create new entry
TODO/bugs In SILC Server
========================
- o removing other's modes on channel seems to be possible due to some
- cumode bug.
+ o Configuration file additions:
- o Topic notifications seem to go double times occasionally to a channel.
+ o Add version handling, to allow, disallow certain versions to
+ connect.
- o Add hashed passwords to silcd.conf file.
+ 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 Backup router related issues
- o Protocol execution timeouts are hard coded, should be
- configurable.
+ o Channel user mode changes are notified unnecessarely when
+ switching to backup router on router crash.
- 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
authentication) then the hostname and the username information could
TODO/bugs In SILC Libraries
===========================
+ o Fix possible buffer overflows in silc_id_render function.
+
o WIN32 silc_net_create_connection_async does not work the same way
than on Unix. Do it with threads on WIN32. The function works but
is not actually async currently.
o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
private and silc_sim_alloc should take necessary arguments.
+ o SILC RNG does not implement random seed files, and they should be
+ implemented.
+
+ o The SilcSocketConnection in the SFTP interface is actually redundant
+ and should perhaps be removed. The application can save it in the
+ context it provides, which is delivered by SFTP libary to all
+ callback functions.
+
+ o EPOC specific additions/changes required:
+
+ o lib/silcutil/epoc routines missing or not completed.
+
+ 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 Global RNG should not be allowed on EPOC, since it won't
+ work. Every function in library that calls the global RNG must
+ also take the RNG context as argument so that application can
+ provide it if it doesn't want to use global RNG.
+
+ o Think some solution to the global crypto lists in lib/silccrypt.
+ They won't work on EPOC.
+
+ o Something needs to be thought to the logging globals as well,
+ like silc_debug etc. They won't work on EPOC. Perhaps logging
+ and debugging is to be disabled on EPOC.
+
+
+TODO in Toolkit Documentation
+=============================
+
+Stuff that needs to be done in order to complete the Tooolkit Reference
+Manual.
+
+ o Lots of ROBOdoc header formatting is undone in lib/silcutil, and
+ lib/silccrypt.
+
+ 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
+ wors differently etc.
+
TODO in SILC Protocol
=====================
payload MAC and not alone by packet MAC. To be included in protocol
version 1.1.
+ 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.
+
+ 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.
-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 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.
+ 12. The router to router connection diagram in spec-xx is showing the
+ primary routers direction to wrong direction. Swap it.
