-TODO for 1.1 And Beyond
-=======================
-
-lib/silccrypt
-=============
-
- o Implement the defined SilcDH API. The definition is in
- lib/silccrypt/silcdh.h.
-
- 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 SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
- Move the SILC Public Key routines away from the crypto library into
- the core library (silccore). silc_pkcs_public/private_key_* routines
- to silc_public/private_key_* routines. The silc_public_key_* routines
- should also automatically handle SILC Public Keys, and other keys
- and certificates as well. Add fe. silcpk.h into silccore. It should
- also include the Public Key Payload encoding and decoding routines.
-
- o Add DSS support.
-
- o Cipher optimizations (asm, that this) at least for i386 would be nice.
-
- o ECDSA and ECDH.
-
-
-lib/silccore/silcpacket.[ch] ****PARTLY DONE****
-============================
-
- o SilcPacketEngine.
-
- o New SILC Packet API.
-
-
-lib/silccore/silcid.[ch]
-========================
-
- 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 silc_id_str2id, silc_id2str to non-allocating routines.
-
-
-lib/silcutil
-============
-
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Zip API must be
- defined.
-
- 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 bool -> SilcBool
-
- o SilcBit, bit field:
-
- #define SilcBit(b) unsigned int b : 1
-
-
-lib/silcutil/silcbuffer.h ****DONE****
-=========================
-
- o Remove the `truelen' field from SilcBuffer as it is entirely
- redundant since we can get the true length of the buffer by
- doing buffer->end - buffer->header. Add silc_buffer_truelen
- macro instead. Consider also removing `len' field too since
- it effectively is buffer->tail - buffer->data, and adding
- silc_buffer_len macro can do the same. These would save
- totally 8 bytes of memory per buffer.
-
-
-lib/silcutil/silcbuffmt.[ch] ****PARTY DONE****
-============================
-
- o SILC_STR_APPEND, _APPEND_TAIL.
-
- o SILC_STR_OFFSET
-
-
-lib/silcutil/silcstack.[ch] ****DONE****
-===========================
-
- o Data stack implementation
-
-
-lib/silcutil/silcstream.[ch] ****DONE****
-============================
-
- o Add abstract SilcStream.
-
-
-lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
-==================================
-
- o Add SilcSocketStream.
-
-
-lib/silcutil/epoc/*
-===================
-
- o lib/silcutil/epoc routines missing or not completed.
-
- o The PKCS#1 also calls global RNG (even though it is not used
- currently in SILC, the interface allows its use).
-
- 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.
-
-
-lib/silcutil/silcschedule*.[ch]
-===============================
-
- o Scheduler can be optimized for FD tasks by changing the fd_queue
- to SilcHashTable instead of using linked list. We need to do
- one-to-one mapping of FD to task and hash table is more efficient
- for this usage.
-
- Also redefine the silc_select to perhaps return a separate
- structure of the events that actually occurred, instead of
- returning the events in the fd_list which is then traversed
- in the generic code to find the changed events. This can be
- made faster by having own struct which includes only the
- changed events, thus the tarversing is faster since the whole
- fd_list is not traversed anymore (it is still traversed in the
- silc_select but at least it removes one extra tarversing later
- for the same list).
-
- Other task queues should be changed to use SilcList.
-
- o Add SILC scheduler's internal routines into a table of implementation
- function pointers, that the generic code then takes as extern from
- implementation. These are the silc_schedule_internal_* routines.
-
- o Change SILC_TASK_CALLBACK to non-static, and remove the macro
- SILC_TASK_CALLBACK_GLOBAL.
-
-
-lib/silcutil/silcasync.[ch] ****DONE****
-===========================
-
- o Add SilcAsyncOperation to utility library. Any function that takes
- callback as an argument must/should return SilcAsyncOperation.
-
-
-lib/silcutil/silctime.[ch] ****DONE****
-===========================
-
- o SilcTime.
-
- o system time, universal, generalized.
-
-
-lib/silcmath
-============
-
- o The SILC MP API function must start returning indication of success
- and failure of the operation.
-
- o Do SilcStack support for silc_mp_init, silc_mp_init_size and other
- any other MP function (including utility ones) that may allocate
- memory.
-
- o All utility functions should be made non-allocating ones.
-
-
-lib/silcasn1 ****PARTLY DONE****
-============
-
- o ASN.1 library
-
- o Header documentation missing.
-
- o Some string encodings missing (copy/paste matter).
-
-
-lib/silcpkix
-============
-
- o PKIX implementation
-
-
-lib/silcutil/silcfsm.[ch]
-=========================
-
- o SILC Finite State Machine API. Replaces SILC Protocol API,
- (see ~silcfsm or ask Pekka).
-
-
-lib/silcutil/silcnet*, lib/silcutil/*/silc*net*
-===============================================
-
- o Add UDP interface
-
- o New network interfaces

-
-
-apps/silcd
-==========
-
- 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 The SERVER_SIGNOFF notify handing is not optimal, because it'll
- cause sending of multiple SIGNOFF notify's instead of the one
- SERVER_SIGNOFF notify that the server received. This should be
- optimized so that the only SERVER_SIGNOFF is sent and not
- SIGNOFF of notify at all (using SIGNOFF takes the idea about
- SERVER_SIGNOFF away entirely).
-
- o Another SERVER_SIGNOFF opt/bugfix: Currently the signoff is
- sent to a client if it is on same channel as the client that
- signoffed. However, the entire SERVER_SIGNOFF list is sent to
- the client, ie. it may receive clients that was not on the
- same channel. This is actually against the specs. It must be
- done per channel. It shouldn't receive the whole list just
- because one client happened to be on same channel.
-
- o MAYBE: The SilcChannelClientEntry can be:
- SilcUInt32 address;
- SilcUInt32 mode;
-
- where address is SilcClientEntry address XOR SilcChannelEntry.
- You can get SilcClientEntry by doing client = chl->address XOR channel,
- and SilcChannelEntry by doing channel = chl->address XOR client.
- As long as the other pointer is always available when accessing the
- structure this can be done.
-
- o Add reference counters to all Silc*Entry structures
-
- o SERVICEs support (plugin, SIM)
-
- o If client's public key is saved in the server (and doing public key
- authentication) then the hostname and the username information could
- be taken from the public key. Should be a configuration option!
-
- 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
- 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 (Fix this to 0.9.x).
-
- o The CMODE cipher & hmac change problem (#101).
