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).
