3 * Changed char *data to unsigned char *data in ID Cache system to
4 support binary data as ID Cache data. Changed code to support
5 binary data in lib/silccore/idcache.c.
7 * Renamed silc_server_packet_relay_command_reply to
8 silc_server_command_reply as it is normal packet receiving
9 function. Rewrote the function to accept command replys for
10 servers and not only for clients.
12 * Mark remote router always as registered server if we are connecting
13 to it. Otherwise, commands sent by the router to us are ignored.
15 * All ID List find routines now returns the ID Cache Entry pointer
18 * WHOIS command works now in router environment, tested with two
19 routers, two servers and two clients.
21 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
22 in router environment (as it is almost equivalent to WHOIS) but
23 hasn't been tested thoroughly. Added new functions:
25 silc_server_command_identify_parse
26 silc_server_command_identify_send_reply
27 silc_server_command_identify_from_client
28 silc_server_command_identify_from_server
30 * Disabled route cache adding because adding two different ID's with
31 same IP replaces the old cache entry thus giving wrong route.
32 The entry->router->connection is always the fastest route anyway
33 so route cache may not be needed. Of course, new routes maybe
34 established after receiving the ID when the entry->router->connection
35 might not be anymore the most optimal.
37 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
39 * Add route cache for received ID for fast routing.
41 * Added silc_server_packet_route to route received packet on router
42 that is not destined to us.
44 * Renamed silc_server_get_route to silc_server_route_get.
46 * Added id_string and id_string_len fields into SilcServer to
47 include encoded ServerID for fast comparing without excess
50 * Cleaned up WHOIS command on server side. Added following static
53 silc_server_command_whois_parse
54 silc_server_command_whois_check
55 silc_server_command_whois_send_reply
56 silc_server_command_whois_from_client
57 silc_server_command_whois_from_server
59 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
60 arguments in command replies. All command functions should be
61 updated to use this macro.
63 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Minor typo fixes on command reply handling on server.
67 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Added silc_server_command_add_to_channel internal routine to add
70 the client to the channel after router has created the channel and
71 sent command reply to the server.
73 * Added generic silc_server_send_command to send any command from
76 * Use static buffer with ID rendering instead of duplicating data.
78 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Fixed a channel user mode bug when joining to a channel server gave
81 everybody channel founder rights, oops.
83 * We mark ourselves as the router of the incoming server connection
84 if we are router ourselves. This way we can check in some packet
85 sending functions whether it is locally connected server. For
86 incoming router connections we put NULL.
88 * For router sending packets locally means now always sending the
89 packet cell wide; to local clients and local servers. For normal
90 server sending packet locally means sending it to only local
93 * Fixed the JOIN command to really work in router environment. If the
94 channel is created it is always created by the router. Router is
95 also responsible of making the initial joining to the channel,
96 sending JOIN notify to the sending server and distributing
97 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
98 does not exist server doesn't do anything else but forward the
99 command to the router which performs everything.
101 * Added silc_server_send_channel_key function to send the Channel Key
104 * Added silc_server_create_channel_key to create new channel key. The
105 channel key is now re-generated everytime someone joins or leaves
106 a channel, as protocol dictates. Note: channel->key_len is the
109 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Splitted server.[ch] finally. Created now packet_send.[ch] and
112 packet_receive.[ch] to separate packet sending and receiving
113 routines. The server.[ch] now includes everything else including
114 actual packet processing (writing and reading data) and other
117 Renamed silc_server_private_message_send_internal to
118 silc_server_send_private_message. The routine is still though
119 used only to relay private messages as server does not send
120 private messages itself.
122 Renamed silc_server_new_channel to silc_server_create_new_channel
123 and added new function sicl_server_new_channel that handles the
124 incoming New Channel packet. Added also new sending function
125 silc_server_send_new_channel to send New Channel Payload.
127 * Added new function silc_server_notify to process incoming notify
128 packet to the server/router. Server may then relay the notify
129 to clients if needed.
131 * Added new function silc_server_new_channel_user to process incoming
132 New Channel User packet. Router will redistribute the packet and
133 send JOIN notify to its local clients and locally connected servers
134 if needed. Normal server will send JOIN notify to its local client
135 on same channel when received this packet. Added also corresponding
136 sending function silc_server_send_new_channel_user to sent the
139 * Added boolean route argument to send_notif_to_channel and
140 packet_send_to_channel functions to attempt to route the packet
141 if it is TRUE and send only locally if it is FALSE.
143 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * silc_server_replace_id now broadcasts the received replace ID
146 packet if it is not broadcast packet already. The router must
147 broadcast to inform other routers about changed ID.
149 * Added backpointer to server's router into SilcServer context in
150 silcd/server_internal.h.
152 * Fixed silc_server_packet_broadcast to send correct broadcast
155 * The channel key is now distributed to the local client as soon
156 as it is received from the router (in router environment) so that
157 no other packet may be sent for the channel until client has
160 * silc_server_remove_channel_user now broadcasts the received
161 Remove Channel User packet if it is not broadcast packet already.
162 The router must broadcast to inform other routers about removed
165 * Added users field into SilcPacketContext that is a reference count
166 of the context. One can increase the reference count by calling
167 silc_packet_context_dup which is now changed to just increase the
168 reference count instead of duplicating the data. The reference
169 count is decresed by calling silc_packet_context_free that will
170 free the data after the reference count hits zero.
172 For now on the packet context and everything allocated into it
173 (including the raw packet from network) must be freed by calling
174 the new silc_packet_context_free function. Added also new function
175 silc_packet_context_alloc that must be used now to allocate the
176 context. This also means that if a routine is asynchronous from
177 silc_[client/server]_packet_parse_type the packet context must
178 be duplicated by calling silc_packet_context_dup. Otherwise it
179 gets free'd after silc_[client/server]_packet_parse_type returns.
180 Also, one must remember that if packet is duplicated then its
181 reference count must be decresed by calling the free function as
182 many times as it was duplicated.
184 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
185 from both client and server.
187 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Made joining to a channel working in router environment.
191 * Cleaned up JOIN command on server side and create function
192 silc_server_command_join_channel internal routine to make the
195 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
197 * Changed silc_command_pending list to SilcDList. Also, added
198 `ident' field to SilcServerCommandPending structure to identify
199 the reply and to call correct callback.
201 Added silc_server_command_pending_check function to replace the
202 corresnponding macro. The silc_command_pending list is not
205 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
206 to set identifier to previously allocated Command Payload. It
207 is used to set identifier for command when resending Command
210 * Added silc_command_payload_encode_payload to encode Command
211 Payload buffer from SilcCommandPayload structure.
213 * Added silc_argument_payload_encode_payload to encode Argument
214 payload buffer from SilcArgumentPayload structure.
216 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Changed WHOIS command to support router connection on server side.
219 The whois request is always sent to router unless the server is
220 standalone server. After server has received the reply from the
221 router will it send the reply to the client.
223 * Added silc_server_packet_broadcast into silcd/server.[ch] to
224 broadcast received broadcast packet. The function is used only
225 by router. The broadcast packet is always sent to the router's
228 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
229 render given ID to printable string, for log files for example.
231 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
233 * Made basic router to router connections working. At least they
234 can now connect to each other but nothing really works the way
235 they are supposed - yet.
237 * Added new initiator token to RouterConnection configuration
238 file in silcd/serverconfig.[ch]. It is used to tell whether we
239 are the initiator to the remote router or whether we'll expect
240 the other end to connect.
242 * Moved registering of listener task to silc_server_init, hence
243 the server starts listenning as soon as it is run, even if it
244 does not have connections to other routers. Let's see how well
247 * Changed default connection retry timeouts for more suitable in
250 * Removed cipher and such arguments from silc_idlist_add_client
251 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
252 Added new function silc_idlist_add_data to add the keys and stuff
255 * Added SilcIDListData structure and added it to SilcClientEntry
256 and SilcServerEntry as their first field in the structure. This
257 way we can explicitly cast the ID entries to the SilcIDListData
258 structure and get common data for the entries. In past, we had
259 to first check what type of connection it is and then cast it to
260 correct ID entry type. Now, we can directly cast the opaque
261 pointer to the SilcIDListData (no matter what ID entry it actually
262 is) and get the data needed.
264 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
266 * Wow, found a bug in scheduler. The scheduler uninitialized itself
267 in some circumstances even if threre were timeout tasks, though not
268 IO tasks, but tasks anyway. Now fixed.
270 * Defined SilcServerConnection structure to hold connection specific
271 stuff about directly connected servers and routers. The definition
272 is currently in silcd/server_internal.h. I thought about having
273 a bit more important role fro this struct but for now it is used
274 only when connecting to other server (or router actually).
276 * Added connecting retry support in server when connecting to
277 router(s). The retry feature implement exponential backoff
278 algorithm. Also, added SilcServerParams structure to hold default
279 parameters for server. For now, it include these retry settings
280 and are hard coded. After server is moded to be as Silc Server
281 Library this structure will be more important.
283 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * Changed client librarys channel->clients table to SilcList and
286 changed code accordingly.
288 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Changed client's channel table to SilcList and changed code
291 accordingly. Also changed SilcChannelClientEntry to include back-
292 pointer to the channel so that client entry can use that structure
293 as list as well and we have fast cross-reference to the channel.
294 This change dramatically decreased the complexity of channel
295 handling with client entry and vice versa (removed one extra
296 loop when searching for channel entry from many functions).
298 * Changed server->sim from table to SilcDList and changed code
301 * NAMES command can now be used from user interface. It will show
302 the user list on the channel, neatly.
304 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
305 Code now saves realname of the user if it becomes available.
307 * Renamed configure.in to configure.in.pre and made ./prepare
308 script to automatically add correct version string to
309 configure.in which it creates from configure.in.pre.
311 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
313 * NAMES command reply now shows users mode with the nickname when
316 * Moved silc_client_ch[u]mode[_char] functions from
317 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
318 place sucks, they are utility functions and should be in some
321 * Fixed some unsigned int's to unsigned short's. Patch by cras.
323 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
326 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Added TRQ (efficient deque and list library) into lib/trq. This is
331 a very good list library that is currently used in the SILC. Defined
332 SilcList API over the library because I didn't like the API very
333 much. See lib/trq/silclist.h for the API and examples of how to
334 use the API. Fixed various places in the code to use the new
335 SilcList API. The SilcList is meant for lists that has a structure
336 already defined as a list. It is not suitable to add just some
337 context to the list (in TRQ, the context is the list actually).
339 So, I defined SilcDList that can be used for the purpose where
340 predefined list structure does not exit. This can be used as
341 such list. Now some context just can be added to the SilcDList.
342 Currently this list is not used in the SILC just yet, though there
343 are a lot places where this can replace dynamically allocated
344 tables and I will fix these places, later, to use SilcDList.
345 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
346 and use TRQ internally).
348 Also fixed some annoying warning messages that the original TRQ
349 code generated. Also minor changes to TRQ's Makefile.in.
351 * Added support for querying by Client ID to both WHOIS and
352 IDENTIFY commands into server, as required by the protocol.
354 * Removed method function pointers from SilcBuffer structure. They
355 weren't used to anything and just increased the context size for
356 no good reason. This change also made silc_buffer_alloc and
357 silc_buffer_free functions inline functions.
359 * Disabled command flooding detection support until it's fixed so
360 that it accepts commands in but does not execute them more than once
363 * Added silc_net_localhost(), to return local hostname, into
364 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
365 that must be initialized before calling silc_client_init.
367 * Added new function: silc_server_send_notify_on_channels to send
368 notify messages to all channels client has joined. It is assured
369 that the message is sent only once per client.
371 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
372 lib/silcutil/silcutil.[ch] as silc_format function. The new
373 function is generic and is used by server as well, not only by
374 the logging routines.
376 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
377 the provided version string was not acceptable. Added new function:
378 silc_ske_check_version into lib/silcske/silcske.h. The function
379 must be implemented by the application (client or server) and it
380 does not reside in the SKE library. The function checks the version
381 string remote end sent.
383 * Added back pointers (to opaque context and to SilcSocketConnection)
384 into SilcPacketContext structure into lib/silccore/silcpacket.h.
386 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
387 duplicate packet context structure.
389 * Changed `notify' client operation to send same arguments as client
390 receives from server except for ID's. ID's are mapped to correct
391 ID entry and that is returned. Also, if channel entry is not sent
392 by server but the notify is for channel the channel entry is sent
393 to application (otherwise application doesn't know that it is for
394 channel (library gets it from packet's Destination ID)).
396 * Added silc_client_remove_from_channels into client library to
397 remove a client from all channels it has joined to. Used when
398 received SIGNOFF notify from server. Added also new function
399 silc_client_replace_from_channels to replace old ID entry with
400 new ID entry on all channels. Used when received NICK_CHANGE
403 * Fixed ID Cache list handling in silc_idlist_get_client in
404 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
405 to get (or query) client by ID.
409 * Added connection authentication status message defined by the
410 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
411 support for these into the code in client and server side.
413 * Added generic function silc_client_send_command to send any command
414 with variable argument list. Application should use this function
415 to send commands if the command functions provided by the library
416 does not suite for the application's user interface needs.
418 * Added new `failure' client operation. Application is notified about
419 received failure packet if client is executing a protocol. In this
420 case the protocol's execution has failed.
422 * Added SKE's end notify to send the SKE_SUCCESS notify message that
423 is required by the protocol.
425 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
426 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
429 * Added status flag to SilcSKE object to indicate realtime status
432 * Application receives now exactly same command reply arguments as
433 the library receives from server. However, if ID is received the
434 corresponding ID entry is returned to the application (eg. Client
435 ID is mapped to correct SilcClientEntry entry and that is returned).
436 Changed command_reply client operation due to this change.
438 * Changed all ID's in commands and in command replys as ID Payloads.
439 Change affected both client and server side codes.
441 All ID's sent in SILC network (with execption of ID's in SILC
442 Packet header) are sent in ID Payload to support variable length
445 * Server now notifies nick changes and notifies all clients on
446 the channels about the new nickname (about the new Client ID,
449 * Implemented CMODE command to change channel modes. Supports all
450 channel modes defined by the protocol specs except ban and invite
451 lists. (Also, private channel key mode is supported but support for
452 setting private channel key in client is missing, thus, this mode
453 has no effect on client side (except that server requires that the
454 client uses private channel key and normal channel traffic does not
457 Also, invite mode works per se, but INVITE command does not work
458 yet correctly, so you can set channel as invite only channel but
459 inviting clients to the channel does not work (it is yet to be
460 thought what's the best way to do it).
462 * Added new command SILC_COMMAND_CUMODE to change user mode on the
463 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
464 Implemented CUMODE command to change user's mode on the channel.
465 Supports all modes defined by the protocol specs.
467 * Added NAMES command reply to return users modes on the channel.
469 * Removed unnecessary and slow ciphers from lib/silccrypt.
471 * Set SO_KEEPALIVE option to connection sockets by default.
473 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
475 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
476 redefined the Notify Payload into protocol specs.
478 * Added silc_id_payload_parse_id to get ID directly from raw
481 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
484 accept searching by Client ID as well.
486 * Added support for LEAVE and SIGNOFF notify types in client library.
488 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
489 to parse ID Payload from raw data.
491 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Added flags parameter into silc_ske_assemble_security_properties
494 function in lib/silcske/silcske.[ch].
496 * Changed notify client operation to fit better for notify messages
497 sent by server. The notify payload received from server is now
498 passed to the application (after parsing it to SilcNotifyPayload).
499 It is application's responsibility to retrieve the arguments
500 from the payload and show the message the way it wants. The message
501 sent by server is implementation specific.
503 * Changed public keys to comply with the protocol specification.
504 Old public keys are not supported anymore and are not compatible.
506 * Removed nickname from Channel Payload as the latest draft removed
507 it. The client must resolve the nickname from the NAMES command
508 reply received when it joined the channel.
510 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
512 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
514 * Fixed some errors in protocol specification drafts.
516 * Created lib/silccore/silcnotify.c to implement Notify Payload
517 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
518 generic payloads described by protocol specifications. The file
519 includes implementations for ID Payload and Argument Payload.
521 * Changed Command Payload implementation to use the new Argument
522 Payload. Changed command_xxxx_payload to command_payload_xxxx
523 to comply with SILC coding conventions.
525 * Added suppport for Argument Payload handling in Notify Payload
526 implementation as protocol requires it. Added the new support
527 into server and client lib as well.
529 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
531 * Added support for multiple nicknames on same channel. [n] is
532 added locally to the nickname if there are more than one same
533 nicknames on the channel.
535 * Server now sends all nicknames that matched WHOIS request.
536 Client also shows the list received from server.
538 * Added TOPIC command to client side. User can now set and show
539 current topic on channel.
541 * Added MOTD command to client and server. Also, server sends the
542 motd when client connects to the server.
544 * Changed version strings to comply ISO 8601.
546 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Fixed protocol error handling in client library. It should now
549 cope even if the SKE fails for some reason.
551 * Made new protocol specification drafts for submitting to IETF.
553 * Implemented TOPIC command to server in silcd/command.c.
555 * Added two new notify types into lib/silccore/silcnotify.h:
556 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
557 notify nickname change and topic setting/change on a channel.
559 * API change of command_reply operation in client library. The
560 application gets now the status type received from server as well.
562 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Removed the function just added to lib/silcutil/silcschedule.[ch].
566 * Cras fixed and optimized the packet handling even further and
567 it should work now. Minor change to the prototype of function
568 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
570 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Added new function into lib/silcutil/silcschedule.[ch]:
573 silc_schedule_with_fd to select() a specified fd. The function
574 returns after timeout expires or data arrives or goes. The
575 function is used by packet routines to wait that all data is
576 received from network.
578 * Fixed data reading from network in lib/silccore/silcpacket.c.
579 The code now assures that all data is read from the fd and then
580 continues packet processing. This was a bug fix since the code
581 used to drop some data in some circumstances.
583 * Added new function into lib/silcclient/client.[ch]:
584 silc_client_start_key_exchange to start key exchange after
585 connection has been established to server. The code internally
586 now uses this funtion but its main purpose was to provide it
587 for applications that perform their own connecting. After
588 application has created a connection it merely calls this
589 function to start the key exchange between client and server.
590 The library takes care of everything else after that.
592 Updated also lib/silcclient/README to explain the usage of
595 * Do not send to application information that connection has
596 been established. Application gets notified it by connect
599 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Applied cras's patch to add silc_schedule_one function. The
602 function runs scheduler once and returns.
604 * Fixed the scheduler after cras messed it up. The timeout
605 handling works now as it's supposed to work.
607 * Added into lib/silccore/ silcnotify.h to include notify
608 message types support. Changed silc_server_send_notify*
609 functions, in server.[ch], to support those new notify types.
610 Added the support for the notify types into client library,
611 as well. Added new notify client operation into ops.h in
614 * Changed silc_server_packet_send_to_channel to send normal
615 packets instead of just channel message packets. The function
616 is now used to send the notify packets to channels. It is not
617 used to send channel message packets anymore, as server never
620 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
621 va_arg()s as it seems to require it nowadays. I guess, if SILC
622 is compiled with older va_arg() the new code should work anyway.
624 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Splitted core library. Core library (lib/silccore) includes
627 now only SILC protocol specific core (and common) components.
628 Created new utility library (lib/silcutil) that includes more
629 generic purpose stuff. The stuff for util library was taken
630 from the old core library. This was minor and easy split.
632 * Created SILC Client Library (lib/silcclient) that includes
633 implementation of the SILC client without user interface. This
634 was major move from silc/ directory. The code has been changed
635 so that it is transparent towards the user interface. The
636 silc/ directory includes now the same user interface as before
637 and it uses the new client library. Read lib/silcclient/README.
638 Basicly, the client library performs everything else related
639 to SILC except user interface handling. Also, configuration
640 files are considered to be part of user interface and library
641 does not handle them.
643 This change also changed a lot of structures, function naming etc.
644 Most important change was that SilcClientWindow object was
645 renamed to SilcClientConnection in the client library. Created
646 also new file lib/silcclient/ops.h. Also added new files
647 silc/local_command.[ch] and silc/client_ops.[ch].
649 All these changes were made to make it easier for user interface
650 designers to create what ever user interface for the SILC client
653 It is also expected that the server will be moved to lib
654 directory as well and SILC Server Library will be created;
655 sometimes in the future.
657 * Removed Local commands from lib/silccore/silccommand.h as
658 they are application specific and new client library does not
659 handle any of those anymore.
661 * Several functions moved to lib/silcutil/silcutilc.[ch] from
662 old client implementation in silc/.
664 * Added support for callback functions in SILC_LOG_* macros.
665 Application can now set its own callbacks that will be called
666 instead of using the default functions that will always print
667 the debug messages to stderr (or stdout). Also, debugging can
668 now be disabled by setting silc_debug to FALSE and re-enabled by
669 setting it to TRUE. Note, that logging will still work even
670 if debugging is disabled.
672 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
673 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
674 silc_log_reset_debug_callbacks.
676 * To enable debugging in silc client one must give now -d
677 option on command line.
679 * Changed silc_schedule_init to automatically allocate task queues
680 if they are not allocated before calling it.
682 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Added GMP 3.1 into math library.
686 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
689 a channel in SILC network. The packet is used by servers and
690 routers to notify other routers that user has left a channel.
691 This little feature was missing until now. Added the feature
692 to protocol specification as well.
694 Added functions: silc_server_send_remove_channel_user and
695 silc_server_remove_channel_user into server.[ch].
697 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
698 lib/silccore/silcpacket.h. However, they are not implemented
701 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Fixed joining to a channel and sending channel messages
704 between server and router. The channel message sending should
705 now work inside a cell.
707 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Fixed the private message sending between server and router.
710 The private message sending should now work inside a cell.
712 * Added silc_server_replace_id into server.[ch] to replace
713 existing ID in the SILC network.
715 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
716 and silc_idlist_replace_server_id into idlist.[ch] in server.
718 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Fixed the server to server connections. Server can again now
721 connect to router. Router to router connections probably does
724 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Added dynamic protocol registering support. Now protocols can
727 registered and unregistered on the fly. Patch by cras.
729 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Added lib/contrib directory to hold routines that some platforms
732 don't have but are needed by SILC.
734 * Added getopt.c, getopt1.c and getopt.h from GNU C library
735 into lin/contrib to provide getopt() and getopt_long() for
736 those who don't have it.
738 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
740 * Added AWAY command to client. When away message is set and
741 client receives a private message packet the client automatically
742 replies to the sender with the away message.
744 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
745 bug seemed to be the cause of recent problems when compiling
748 * Added version detection support to SKE protocol specification
749 and added the new changes to the SKE implementation as well.
750 There were other minor changes in the SKE protocol as well.
752 Many changes in lib/silcske/silcske.[ch] and in
753 lib/silcske/payload.[ch].
755 * Added ^U functionality, clear input line. Patch from cras.
757 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Mainly small bugfixes on core library. Fixed some debugging
760 logging and buffer overflow in silclog.c.
762 * Updated config.sub and config.guess on the distribution tree.
764 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
766 * Added command lagging support in server. Client may execute
767 commands now only once in two seconds.
769 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Optimized packet reception. MAC computation and checking is now
772 also more optimized. A lot previously duplicated code is now
773 used as generic by both client and server.
775 * Fixed key pair generation in clientutil.c
777 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Added into lib/silccore/silcbufutil.[ch] new function;
782 * Moved generic packet sending/encryption functions to
783 lib/silccore/silcpacket.[ch] from client and server. Some
784 rewriting of the functions.
786 * Moved all generic packet reception/decryption functions to
787 lib/silccore/silcpacket.[ch] from client and server. The
788 packet processing is now much cleaner in both client and server.
789 These were major changes in both client and server.
791 * Created many common functions in server to do packet sending.
792 Previously code were duplicated a lot, this has been removed
795 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Rewrote major parts of the ID cache system. Don't know
798 whether it is better now or not but at least the API is more
801 * Major rewrite on ID cache stuff on client because of the ID
802 cache API changes. Added idlist.c to client.
804 * Also major rewrite on ID cache stuff on server as well.
805 Major rewrite of idlist.[ch]. SilcXXXList's are now named
806 SilcXXXEntry's. We won't keep anymore idlist specific pointers
807 in hand, instead they are all put into the ID cache system now.
808 All server_idlist_* routines uses ID cache now instead of
809 traversing its own lists (those lists does not exist anymore).
810 SilcIDList though still exists. Also, SilcXXXEntry's are
813 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Finally made the SKE implementation compliant to the protocol
816 specification. All mp integers are now binary encoded as
817 opposed being HEX encoded.
819 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
822 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
823 functions: silc_[encode/decode]_pem. Also added function
824 silc_encode_pem_file to PEM encode with newlines ('\n') for
827 * SILC public keys are now encoded either PEM or binary. Same
828 option is for private keys as well. By default private keys
829 are binary encoded and public keys PEM encoded. Silly HEX
830 encoding were removed.
832 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
833 function to create fingerprints.
835 * Fixed a bug in SHA1; does not change the original data anymore.
837 * Partly implemented INFO command on client and server side.
838 Fixed CLEAR command. Changes to SERVER command; show current
839 server(s) when giving command without arguments. Added
840 VERSION command to client.
842 * Added check to server that unregistered connections cannot
843 execute commands (unless it is specificly allowed).
845 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Fixed screen refresh.
849 * Fixed channel joining bug from client. On some circumstances
850 client tried to join to a channel it had already joined.
852 * Added public key verification process into client's protocol.c.
853 The client now verifies the public key from user and saves
854 it into ~./silc/serverkeys/ directory.
856 Added into: clientutil.[ch]: silc_client_verify_server_key.
858 * Changed SKE protocol's silc_ske_initiator_finish function
859 to accept callback function that verifies the received public
860 key. Removed old silc_ske_verify_public_key function.
862 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
865 silc_pkcs_private_key[_data]_set.
867 * Made the password and public authentication more cleaner in
870 * Removed historic and obsolete protocol `channel_auth' from
871 both client and server.
873 * Removed wrong way of sending command status messages from
874 server to client in server's command.c. The old way violated
875 protocol specification.
877 Changes to silccore/silccommand.[ch]: removed
878 silc_command_encode_status_payload -> not needed anymore,
879 changed silc_command_encode_payload_va to accept extra
880 argument on variable argument list. The argument type must
881 now be provided to the function. Also, added new function:
882 silc_command_encode_reply_payload_va which is same as
883 normal command_encode_payload_va except command status type
884 is provided as extra argument.
886 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
888 * Added ~./silc directory handling. The directory includes the
889 public and private keys for the client.
891 Added silc_client_check_silc_dir, silc_client_create_identifier
892 and silc_client_load_keys.
894 * Implemented SILC protocol compliant public key. Added public
895 and private key saving to and loading from files.
897 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
898 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
899 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
900 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
901 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
903 Implemented: silc_pkcs_save_[public/private]_key[_data] and
904 silc_pkcs_load_[public/private]_key.
906 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Added silc_server_get_route (route.[ch]) to get connection
909 data for the fastest route for given ID.
911 * Implemented INVITE command on client and server. The command
912 were re-defined in the SILC Protocol Specification and the
913 implementation now complies with the specification.
915 * Implemented PING command on client and server.
917 * Implemented NAMES command on client and server. The server side
918 supports currently only normal server not router server yet.
919 Some changes to NAMES definition in SILC protocol specification.
921 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Implemented LEAVE command on client and server.
925 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
926 again. This change was made to the protocol as well. Server
927 should not violate the protocol specification anymore.
929 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
932 was tested. SOCKS4 was not but should work anyway.
