-TODO for SILC Client 1.0 branch
-===============================
+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.
+
- o Bugs reported on the mailing list that will be fixed eventually.
- The numbers are arbitrary and assigned by me (c0ffee), bugs in
- parentheses are fixed.
+lib/silccore/silcpacket.[ch] ****PARTLY DONE****
+============================
- (#1 Ignore ALL doesn't ignore target using /me)
- #2 specification of the silc network
- (#3 expired private key dialogue doesn't work)
- #4 silc client allows setting non-utf8 topics
- #5 SILC-client displaying wrong totals with /names
+ o SilcPacketEngine.
+ o New SILC Packet API.
-TODO for SILC Server 1.0
+
+lib/silccore/silcid.[ch]
========================
- o BUG: silc_idlist_del_client had been called but sock->user_data remained
- and pointed to invalid pointer. Where it was called is not known.
+ 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
+
- o Basic UTF-8 stringprep profile that makes sure UTF-8 strings are
- as defined in spec-08 section 3.13.
+lib/silcutil/silcbuffer.h ****DONE****
+=========================
- o Server sometimes connects more than once to router and keeps
- connecting even though connection exists.
+ 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.
- o Testing
+lib/silcutil/silcbuffmt.[ch] ****PARTY DONE****
+============================
-TODO/bugs In SILC Libraries
+ o SILC_STR_APPEND, _APPEND_TAIL.
+
+ o SILC_STR_OFFSET
+
+
+lib/silcutil/silcstack.[ch] ****DONE****
===========================
- o Test cases for all payload encoding and decoding routins in lib/silccore/
+ 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] ****DONE****
+===============================
+
+ 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] ****DONE****
+=========================
+
+ o SILC Finite State Machine API. Replaces SILC Protocol API,
+
+
+lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
+===============================================
+
+ o Add UDP interface
+
+ o New network interfaces
+
+ o Other functions should remain as they are since these new functions have
+ to use them. This way we also provide them for applications that want
+ to handle the sockets by themself.
+
+
+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 Test cases for math library routines in lib/silcmath/
+ o MAYBE: The SilcChannelClientEntry can be:
+ SilcUInt32 address;
+ SilcUInt32 mode;
- o Implement new version of SFTP protocol (missing versions 4 and 5, we
- have version 3).
+ 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
-TODO in Toolkit Documentation
-=============================
+ o SERVICEs support (plugin, SIM)
-Stuff that needs to be done in order to complete the Toolkit Reference
-Manual (Do these to 0.9.x).
+ 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 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 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 Searching of predefined keywords, exact and partial matches (would be
- nice).
+ o The CMODE cipher & hmac change problem (#101).
