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