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 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
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 strerror messages from premature EOF's to signoff messages.
- (add perhaps a socket error thingy to SilcSocketConnection).
+ 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 hashed passwords to silcd.conf file.
o Backup router related issues
TODO/bugs In SILC Libraries
===========================
- o make install copies the symblic links from lib/silcsim/ and not
- modules.
-
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.
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.

TODO After 1.0
==============
- 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).
+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 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.
-
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
Other package that should be checked is the NSS's X509 library,
which I like more over OpenSSL package.
- o SSH2 public keys support.
+ o SSH2 public keys support, allowing the use of SSH2 public keys in
+ SILC.
- o OpenPGP certificate support.
+ 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.
