1 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed some minor bugs in client when sending WHOIS command. The
4 arguments was in wrong order.
6 * Removed statis function add_to_channel from server in
7 silcd/command.c that was previously used with the joining but
10 * Tested USERS command in router environment successfully with two
11 routers, two servers and two clients.
13 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
15 * Reorganized the USERS command and command reply in client library
16 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
17 When the command is given by user we register a pending command
18 callback that will reprocess the command after the reply has been
19 received from the server. When reprocessing the packet we then
20 display the information. Thus, the USERS information is displayed
21 now in the command callback instead of in the command reply
22 callback. The processing of the command is same as previously
23 when server has sent the command reply in the JOINing process.
25 * Added to USERS command in silcd/command_reply.c to join the client,
26 we didn't use to know about, to the channel after we've created
27 a client entry for it. Also, for clienet we did know already still
28 check whether it is on the channel or not and add it if not.
30 * Removed silc_server_command_join_notify as the function and its
33 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Changed the client's pending command handling to the same as the
36 server's pending command handling. It is also now possible to
37 execute command reply functions from other command reply
38 function as the function callbacks for commands and command
39 replies are one and same. The pending commands are not static
40 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
41 in client connection context. Thus, pending commands are server
42 connection specific as it is convenient.
44 Changed the function silc_client_command_pending and
45 silc_client_command_pending_del and added new function
46 silc_client_command_pending_check. Removed the
47 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
50 * Added cmd_ident, current command identifier, to the client
51 connection context in lib/silcclient/client.h to keep track on
52 command identifiers used in command sending. Client's command reply
53 function handling now supports the mandatory command identifiers.
55 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
56 funtions in client to fully support pending command callbacks.
58 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
59 as one of the arguments to the application in the command reply
62 * NOTE: The FORWARDED flag is depracated. It used to be depracated
63 before first releasing SILC but came back. Now it is removed again
64 and should come back nomore. The FORWARDED flag was used only
65 by the JOINing procedure by forwarding the command packet to router.
66 Now, the JOINing procedure has been changed to more generic (due
67 to various router environment issues) and FORWARDED is not needed
68 anymore for anything. The protocol specification is yet to be
71 Now, removed silc_server_packet_forward from server and the flag
72 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
74 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
76 * Renamed NAMES command to USERS command. The NAMES was named that
77 due to historical reasons. Now it is renamed. Also, rewrote
78 parts of the USERS command. The nickname list is not sent anymore
79 by the server. Only Client ID and mode lists are sent in the USERS
80 command. Changed this also to the protocol specification.
82 The client now resolves the names and stuff after it receives
83 the USERS list from the server when joining to the channel.
85 * WHOIS and IDENTIFY commands has been changed to support multiple
86 Client ID's per command. One can now search for multiple users
87 in the network by sending only one WHOIS or IDENTIFY command.
88 Changed the code and the protocol specifications.
90 * Removed silc_server_command_identify_parse and changed that IDENTIFY
91 uses silc_server_command_whois_parse to parse the request. */
93 * If normal server, do not parse the WHOIS and IDENTIFY requests
94 before sending it to the router. Saves some time.
96 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Fixed JOIN command on client library. Wrong number of arguments
99 used to crash the client.
101 * Added silc_server_channel_has_global function to check whether
102 channel has global users or not.
104 * Added silc_server_channel_has_local function to check whether channel
105 has locally connected clients on the channel.
107 * The silc_server_remove_from_one_channel now checks whether the
108 channel has global users or not after given client was removed from
109 the channel. It also checks whether the channel has local clients
110 on the channel anymore. If it does not have then the channel entry
111 is removed as it is not needed anymore.
113 * The silc_server_notify now checks on JOIN notify whether the joining
114 client is one of locally connected or global. If it is global then
115 the channel has now global users on the channel and that is marked
116 to the channel entry. Also, it now saves the global client to
117 global list who is joining and JOINs it to the channel. This is
118 for normal server, that is.
120 Changed silc_server_send_notify_on_channel,
121 silc_server_packet_relay_to_channel and
122 silc_server_packet_send_to_channel check if we are normal server
123 and client has router set (ie. global client) do not send the
124 message to that client, as it is already routed to our router.
126 * Implemented LEAVE notify type handling in silc_server_notify
129 * Tested LEAVE command in router environment successfully. Tested
130 with two routers, two servers and two clients.
134 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
136 * Implemented SIGNOFF notify type handling in silc_server_notify
139 * silc_server_remove_id now removes the client entry from all channels
140 it has joined and thusly sends SIGNOFF notify type.
142 * Rewrote the NAMES list generation in server by removing two excess
143 loops. The lists are created now inside one loop.
145 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
147 * silc_server_remove_channel_user checks now also global list
148 for channel and client.
150 * silc_server_new_channel_user checks now both local and global
151 list for channel and client. Fixed a bug in client id decoding.
152 Used to decode wrong buffer.
154 * silc_server_channel_message checks now both local and global
155 list for channel entry.
157 * Tested channel joining (hence JOIN) in router environment
158 successfully. Tested with two routers, two servers and two
161 * Tested channel message sending in router environment successfully.
163 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Added silc_server_save_channel_key into server.[ch] to save the
166 received channel key in Channel Key payload processing. It is
167 also used in JOIN command reply handling.
169 Equivalent function silc_client_save_channel_key added into
170 client.[ch] into client library.
172 * Changed JOIN command reply to send information whether the channel
173 was created or not (is existing already) and the channel key
174 payload. Changed protocol specs accordingly.
176 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
177 the request was sent by ID and not by nickname. Crashed on
180 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
183 now correctly save the received data.
185 * silc_server_free_sock_user_data now notifies routers in the
186 network about entities leaving the network.
188 At the same time implemented functions silc_server_remove_id
189 and silc_server_send_remove_id to receive and send REMOVE_ID
190 packets. The packet is used to notify routers in the network
191 about leaving entities. The ID removed will become invalid in
194 * Added function silc_idlist_del_server into server. Removes and
195 free's server entry from ID list.
197 * silc_server_private_message function now checks, if we are router,
198 that the destination ID really is valid ID, naturally.
200 * In router when NEW_ID packet is received (for new client) the
201 hash of the Client ID is saved in the ID Cache but the
202 client->nickname is set to NULL, instead of putting the hash
205 IDENTIFY command now also checks that client->nickname must be
206 valid. If it is not if will request the data from the server who
207 owns the client. Added new function
208 silc_server_command_identify_check.
210 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
211 to set the command to already allocated Command Payload.
213 * Tested private message sending in router environment with two
214 routers, two servers and two clients. Fixed minor bugs and now
217 * Fixed segfault from client's NAMES command. Used to crash if
220 * Forwarded packets must not be routed even if it is not destined
221 to the receiver. Changed server code comply with this.
223 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Added `require_reverse_mapping' boolean value to ServerParams
226 structure. If TRUE (not default) the server will require that
227 the connecting host has fully qualified domain name.
229 If the reverse mapping is not required and hostname could not be
230 found the IP address is used as hostname.
232 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
234 * Implemented version string checking to both client and server.
235 The check is incomplete currently due to the abnormal version
236 strings used in development version of SILC.
238 * Changed all command functions in server to use the new
241 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
243 * Changed char *data to unsigned char *data in ID Cache system to
244 support binary data as ID Cache data. Changed code to support
245 binary data in lib/silccore/idcache.c.
247 * Renamed silc_server_packet_relay_command_reply to
248 silc_server_command_reply as it is normal packet receiving
249 function. Rewrote the function to accept command replys for
250 servers and not only for clients.
252 * Mark remote router always as registered server if we are connecting
253 to it. Otherwise, commands sent by the router to us are ignored.
255 * All ID List find routines now returns the ID Cache Entry pointer
256 as well if requested.
258 * WHOIS command works now in router environment, tested with two
259 routers, two servers and two clients.
261 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
262 in router environment (as it is almost equivalent to WHOIS) but
263 hasn't been tested thoroughly. Added new functions:
265 silc_server_command_identify_parse
266 silc_server_command_identify_send_reply
267 silc_server_command_identify_from_client
268 silc_server_command_identify_from_server
270 * Disabled route cache adding because adding two different ID's with
271 same IP replaces the old cache entry thus giving wrong route.
272 The entry->router->connection is always the fastest route anyway
273 so route cache may not be needed. Of course, new routes maybe
274 established after receiving the ID when the entry->router->connection
275 might not be anymore the most optimal.
277 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Add route cache for received ID for fast routing.
281 * Added silc_server_packet_route to route received packet on router
282 that is not destined to us.
284 * Renamed silc_server_get_route to silc_server_route_get.
286 * Added id_string and id_string_len fields into SilcServer to
287 include encoded ServerID for fast comparing without excess
288 encoding of the ID's.
290 * Cleaned up WHOIS command on server side. Added following static
293 silc_server_command_whois_parse
294 silc_server_command_whois_check
295 silc_server_command_whois_send_reply
296 silc_server_command_whois_from_client
297 silc_server_command_whois_from_server
299 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
300 arguments in command replies. All command functions should be
301 updated to use this macro.
303 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * Minor typo fixes on command reply handling on server.
307 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Added silc_server_command_add_to_channel internal routine to add
310 the client to the channel after router has created the channel and
311 sent command reply to the server.
313 * Added generic silc_server_send_command to send any command from
316 * Use static buffer with ID rendering instead of duplicating data.
318 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Fixed a channel user mode bug when joining to a channel server gave
321 everybody channel founder rights, oops.
323 * We mark ourselves as the router of the incoming server connection
324 if we are router ourselves. This way we can check in some packet
325 sending functions whether it is locally connected server. For
326 incoming router connections we put NULL.
328 * For router sending packets locally means now always sending the
329 packet cell wide; to local clients and local servers. For normal
330 server sending packet locally means sending it to only local
333 * Fixed the JOIN command to really work in router environment. If the
334 channel is created it is always created by the router. Router is
335 also responsible of making the initial joining to the channel,
336 sending JOIN notify to the sending server and distributing
337 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
338 does not exist server doesn't do anything else but forward the
339 command to the router which performs everything.
341 * Added silc_server_send_channel_key function to send the Channel Key
344 * Added silc_server_create_channel_key to create new channel key. The
345 channel key is now re-generated everytime someone joins or leaves
346 a channel, as protocol dictates. Note: channel->key_len is the
349 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Splitted server.[ch] finally. Created now packet_send.[ch] and
352 packet_receive.[ch] to separate packet sending and receiving
353 routines. The server.[ch] now includes everything else including
354 actual packet processing (writing and reading data) and other
357 Renamed silc_server_private_message_send_internal to
358 silc_server_send_private_message. The routine is still though
359 used only to relay private messages as server does not send
360 private messages itself.
362 Renamed silc_server_new_channel to silc_server_create_new_channel
363 and added new function sicl_server_new_channel that handles the
364 incoming New Channel packet. Added also new sending function
365 silc_server_send_new_channel to send New Channel Payload.
367 * Added new function silc_server_notify to process incoming notify
368 packet to the server/router. Server may then relay the notify
369 to clients if needed.
371 * Added new function silc_server_new_channel_user to process incoming
372 New Channel User packet. Router will redistribute the packet and
373 send JOIN notify to its local clients and locally connected servers
374 if needed. Normal server will send JOIN notify to its local client
375 on same channel when received this packet. Added also corresponding
376 sending function silc_server_send_new_channel_user to sent the
379 * Added boolean route argument to send_notif_to_channel and
380 packet_send_to_channel functions to attempt to route the packet
381 if it is TRUE and send only locally if it is FALSE.
383 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * silc_server_replace_id now broadcasts the received replace ID
386 packet if it is not broadcast packet already. The router must
387 broadcast to inform other routers about changed ID.
389 * Added backpointer to server's router into SilcServer context in
390 silcd/server_internal.h.
392 * Fixed silc_server_packet_broadcast to send correct broadcast
395 * The channel key is now distributed to the local client as soon
396 as it is received from the router (in router environment) so that
397 no other packet may be sent for the channel until client has
400 * silc_server_remove_channel_user now broadcasts the received
401 Remove Channel User packet if it is not broadcast packet already.
402 The router must broadcast to inform other routers about removed
405 * Added users field into SilcPacketContext that is a reference count
406 of the context. One can increase the reference count by calling
407 silc_packet_context_dup which is now changed to just increase the
408 reference count instead of duplicating the data. The reference
409 count is decresed by calling silc_packet_context_free that will
410 free the data after the reference count hits zero.
412 For now on the packet context and everything allocated into it
413 (including the raw packet from network) must be freed by calling
414 the new silc_packet_context_free function. Added also new function
415 silc_packet_context_alloc that must be used now to allocate the
416 context. This also means that if a routine is asynchronous from
417 silc_[client/server]_packet_parse_type the packet context must
418 be duplicated by calling silc_packet_context_dup. Otherwise it
419 gets free'd after silc_[client/server]_packet_parse_type returns.
420 Also, one must remember that if packet is duplicated then its
421 reference count must be decresed by calling the free function as
422 many times as it was duplicated.
424 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
425 from both client and server.
427 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
429 * Made joining to a channel working in router environment.
431 * Cleaned up JOIN command on server side and create function
432 silc_server_command_join_channel internal routine to make the
435 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Changed silc_command_pending list to SilcDList. Also, added
438 `ident' field to SilcServerCommandPending structure to identify
439 the reply and to call correct callback.
441 Added silc_server_command_pending_check function to replace the
442 corresnponding macro. The silc_command_pending list is not
445 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
446 to set identifier to previously allocated Command Payload. It
447 is used to set identifier for command when resending Command
450 * Added silc_command_payload_encode_payload to encode Command
451 Payload buffer from SilcCommandPayload structure.
453 * Added silc_argument_payload_encode_payload to encode Argument
454 payload buffer from SilcArgumentPayload structure.
456 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * Changed WHOIS command to support router connection on server side.
459 The whois request is always sent to router unless the server is
460 standalone server. After server has received the reply from the
461 router will it send the reply to the client.
463 * Added silc_server_packet_broadcast into silcd/server.[ch] to
464 broadcast received broadcast packet. The function is used only
465 by router. The broadcast packet is always sent to the router's
468 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
469 render given ID to printable string, for log files for example.
471 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Made basic router to router connections working. At least they
474 can now connect to each other but nothing really works the way
475 they are supposed - yet.
477 * Added new initiator token to RouterConnection configuration
478 file in silcd/serverconfig.[ch]. It is used to tell whether we
479 are the initiator to the remote router or whether we'll expect
480 the other end to connect.
482 * Moved registering of listener task to silc_server_init, hence
483 the server starts listenning as soon as it is run, even if it
484 does not have connections to other routers. Let's see how well
487 * Changed default connection retry timeouts for more suitable in
490 * Removed cipher and such arguments from silc_idlist_add_client
491 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
492 Added new function silc_idlist_add_data to add the keys and stuff
495 * Added SilcIDListData structure and added it to SilcClientEntry
496 and SilcServerEntry as their first field in the structure. This
497 way we can explicitly cast the ID entries to the SilcIDListData
498 structure and get common data for the entries. In past, we had
499 to first check what type of connection it is and then cast it to
500 correct ID entry type. Now, we can directly cast the opaque
501 pointer to the SilcIDListData (no matter what ID entry it actually
502 is) and get the data needed.
504 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Wow, found a bug in scheduler. The scheduler uninitialized itself
507 in some circumstances even if threre were timeout tasks, though not
508 IO tasks, but tasks anyway. Now fixed.
510 * Defined SilcServerConnection structure to hold connection specific
511 stuff about directly connected servers and routers. The definition
512 is currently in silcd/server_internal.h. I thought about having
513 a bit more important role fro this struct but for now it is used
514 only when connecting to other server (or router actually).
516 * Added connecting retry support in server when connecting to
517 router(s). The retry feature implement exponential backoff
518 algorithm. Also, added SilcServerParams structure to hold default
519 parameters for server. For now, it include these retry settings
520 and are hard coded. After server is moded to be as Silc Server
521 Library this structure will be more important.
523 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
525 * Changed client librarys channel->clients table to SilcList and
526 changed code accordingly.
528 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Changed client's channel table to SilcList and changed code
531 accordingly. Also changed SilcChannelClientEntry to include back-
532 pointer to the channel so that client entry can use that structure
533 as list as well and we have fast cross-reference to the channel.
534 This change dramatically decreased the complexity of channel
535 handling with client entry and vice versa (removed one extra
536 loop when searching for channel entry from many functions).
538 * Changed server->sim from table to SilcDList and changed code
541 * NAMES command can now be used from user interface. It will show
542 the user list on the channel, neatly.
544 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
545 Code now saves realname of the user if it becomes available.
547 * Renamed configure.in to configure.in.pre and made ./prepare
548 script to automatically add correct version string to
549 configure.in which it creates from configure.in.pre.
551 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * NAMES command reply now shows users mode with the nickname when
556 * Moved silc_client_ch[u]mode[_char] functions from
557 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
558 place sucks, they are utility functions and should be in some
561 * Fixed some unsigned int's to unsigned short's. Patch by cras.
563 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
566 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Added TRQ (efficient deque and list library) into lib/trq. This is
571 a very good list library that is currently used in the SILC. Defined
572 SilcList API over the library because I didn't like the API very
573 much. See lib/trq/silclist.h for the API and examples of how to
574 use the API. Fixed various places in the code to use the new
575 SilcList API. The SilcList is meant for lists that has a structure
576 already defined as a list. It is not suitable to add just some
577 context to the list (in TRQ, the context is the list actually).
579 So, I defined SilcDList that can be used for the purpose where
580 predefined list structure does not exit. This can be used as
581 such list. Now some context just can be added to the SilcDList.
582 Currently this list is not used in the SILC just yet, though there
583 are a lot places where this can replace dynamically allocated
584 tables and I will fix these places, later, to use SilcDList.
585 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
586 and use TRQ internally).
588 Also fixed some annoying warning messages that the original TRQ
589 code generated. Also minor changes to TRQ's Makefile.in.
591 * Added support for querying by Client ID to both WHOIS and
592 IDENTIFY commands into server, as required by the protocol.
594 * Removed method function pointers from SilcBuffer structure. They
595 weren't used to anything and just increased the context size for
596 no good reason. This change also made silc_buffer_alloc and
597 silc_buffer_free functions inline functions.
599 * Disabled command flooding detection support until it's fixed so
600 that it accepts commands in but does not execute them more than once
603 * Added silc_net_localhost(), to return local hostname, into
604 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
605 that must be initialized before calling silc_client_init.
607 * Added new function: silc_server_send_notify_on_channels to send
608 notify messages to all channels client has joined. It is assured
609 that the message is sent only once per client.
611 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
612 lib/silcutil/silcutil.[ch] as silc_format function. The new
613 function is generic and is used by server as well, not only by
614 the logging routines.
616 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
617 the provided version string was not acceptable. Added new function:
618 silc_ske_check_version into lib/silcske/silcske.h. The function
619 must be implemented by the application (client or server) and it
620 does not reside in the SKE library. The function checks the version
621 string remote end sent.
623 * Added back pointers (to opaque context and to SilcSocketConnection)
624 into SilcPacketContext structure into lib/silccore/silcpacket.h.
626 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
627 duplicate packet context structure.
629 * Changed `notify' client operation to send same arguments as client
630 receives from server except for ID's. ID's are mapped to correct
631 ID entry and that is returned. Also, if channel entry is not sent
632 by server but the notify is for channel the channel entry is sent
633 to application (otherwise application doesn't know that it is for
634 channel (library gets it from packet's Destination ID)).
636 * Added silc_client_remove_from_channels into client library to
637 remove a client from all channels it has joined to. Used when
638 received SIGNOFF notify from server. Added also new function
639 silc_client_replace_from_channels to replace old ID entry with
640 new ID entry on all channels. Used when received NICK_CHANGE
643 * Fixed ID Cache list handling in silc_idlist_get_client in
644 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
645 to get (or query) client by ID.
649 * Added connection authentication status message defined by the
650 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
651 support for these into the code in client and server side.
653 * Added generic function silc_client_send_command to send any command
654 with variable argument list. Application should use this function
655 to send commands if the command functions provided by the library
656 does not suite for the application's user interface needs.
658 * Added new `failure' client operation. Application is notified about
659 received failure packet if client is executing a protocol. In this
660 case the protocol's execution has failed.
662 * Added SKE's end notify to send the SKE_SUCCESS notify message that
663 is required by the protocol.
665 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
666 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
669 * Added status flag to SilcSKE object to indicate realtime status
672 * Application receives now exactly same command reply arguments as
673 the library receives from server. However, if ID is received the
674 corresponding ID entry is returned to the application (eg. Client
675 ID is mapped to correct SilcClientEntry entry and that is returned).
676 Changed command_reply client operation due to this change.
678 * Changed all ID's in commands and in command replys as ID Payloads.
679 Change affected both client and server side codes.
681 All ID's sent in SILC network (with execption of ID's in SILC
682 Packet header) are sent in ID Payload to support variable length
685 * Server now notifies nick changes and notifies all clients on
686 the channels about the new nickname (about the new Client ID,
689 * Implemented CMODE command to change channel modes. Supports all
690 channel modes defined by the protocol specs except ban and invite
691 lists. (Also, private channel key mode is supported but support for
692 setting private channel key in client is missing, thus, this mode
693 has no effect on client side (except that server requires that the
694 client uses private channel key and normal channel traffic does not
697 Also, invite mode works per se, but INVITE command does not work
698 yet correctly, so you can set channel as invite only channel but
699 inviting clients to the channel does not work (it is yet to be
700 thought what's the best way to do it).
702 * Added new command SILC_COMMAND_CUMODE to change user mode on the
703 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
704 Implemented CUMODE command to change user's mode on the channel.
705 Supports all modes defined by the protocol specs.
707 * Added NAMES command reply to return users modes on the channel.
709 * Removed unnecessary and slow ciphers from lib/silccrypt.
711 * Set SO_KEEPALIVE option to connection sockets by default.
713 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
715 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
716 redefined the Notify Payload into protocol specs.
718 * Added silc_id_payload_parse_id to get ID directly from raw
721 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
723 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
724 accept searching by Client ID as well.
726 * Added support for LEAVE and SIGNOFF notify types in client library.
728 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
729 to parse ID Payload from raw data.
731 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Added flags parameter into silc_ske_assemble_security_properties
734 function in lib/silcske/silcske.[ch].
736 * Changed notify client operation to fit better for notify messages
737 sent by server. The notify payload received from server is now
738 passed to the application (after parsing it to SilcNotifyPayload).
739 It is application's responsibility to retrieve the arguments
740 from the payload and show the message the way it wants. The message
741 sent by server is implementation specific.
743 * Changed public keys to comply with the protocol specification.
744 Old public keys are not supported anymore and are not compatible.
746 * Removed nickname from Channel Payload as the latest draft removed
747 it. The client must resolve the nickname from the NAMES command
748 reply received when it joined the channel.
750 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
752 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Fixed some errors in protocol specification drafts.
756 * Created lib/silccore/silcnotify.c to implement Notify Payload
757 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
758 generic payloads described by protocol specifications. The file
759 includes implementations for ID Payload and Argument Payload.
761 * Changed Command Payload implementation to use the new Argument
762 Payload. Changed command_xxxx_payload to command_payload_xxxx
763 to comply with SILC coding conventions.
765 * Added suppport for Argument Payload handling in Notify Payload
766 implementation as protocol requires it. Added the new support
767 into server and client lib as well.
769 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Added support for multiple nicknames on same channel. [n] is
772 added locally to the nickname if there are more than one same
773 nicknames on the channel.
775 * Server now sends all nicknames that matched WHOIS request.
776 Client also shows the list received from server.
778 * Added TOPIC command to client side. User can now set and show
779 current topic on channel.
781 * Added MOTD command to client and server. Also, server sends the
782 motd when client connects to the server.
784 * Changed version strings to comply ISO 8601.
786 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Fixed protocol error handling in client library. It should now
789 cope even if the SKE fails for some reason.
791 * Made new protocol specification drafts for submitting to IETF.
793 * Implemented TOPIC command to server in silcd/command.c.
795 * Added two new notify types into lib/silccore/silcnotify.h:
796 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
797 notify nickname change and topic setting/change on a channel.
799 * API change of command_reply operation in client library. The
800 application gets now the status type received from server as well.
802 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Removed the function just added to lib/silcutil/silcschedule.[ch].
806 * Cras fixed and optimized the packet handling even further and
807 it should work now. Minor change to the prototype of function
808 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
810 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Added new function into lib/silcutil/silcschedule.[ch]:
813 silc_schedule_with_fd to select() a specified fd. The function
814 returns after timeout expires or data arrives or goes. The
815 function is used by packet routines to wait that all data is
816 received from network.
818 * Fixed data reading from network in lib/silccore/silcpacket.c.
819 The code now assures that all data is read from the fd and then
820 continues packet processing. This was a bug fix since the code
821 used to drop some data in some circumstances.
823 * Added new function into lib/silcclient/client.[ch]:
824 silc_client_start_key_exchange to start key exchange after
825 connection has been established to server. The code internally
826 now uses this funtion but its main purpose was to provide it
827 for applications that perform their own connecting. After
828 application has created a connection it merely calls this
829 function to start the key exchange between client and server.
830 The library takes care of everything else after that.
832 Updated also lib/silcclient/README to explain the usage of
835 * Do not send to application information that connection has
836 been established. Application gets notified it by connect
839 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
841 * Applied cras's patch to add silc_schedule_one function. The
842 function runs scheduler once and returns.
844 * Fixed the scheduler after cras messed it up. The timeout
845 handling works now as it's supposed to work.
847 * Added into lib/silccore/ silcnotify.h to include notify
848 message types support. Changed silc_server_send_notify*
849 functions, in server.[ch], to support those new notify types.
850 Added the support for the notify types into client library,
851 as well. Added new notify client operation into ops.h in
854 * Changed silc_server_packet_send_to_channel to send normal
855 packets instead of just channel message packets. The function
856 is now used to send the notify packets to channels. It is not
857 used to send channel message packets anymore, as server never
860 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
861 va_arg()s as it seems to require it nowadays. I guess, if SILC
862 is compiled with older va_arg() the new code should work anyway.
864 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Splitted core library. Core library (lib/silccore) includes
867 now only SILC protocol specific core (and common) components.
868 Created new utility library (lib/silcutil) that includes more
869 generic purpose stuff. The stuff for util library was taken
870 from the old core library. This was minor and easy split.
872 * Created SILC Client Library (lib/silcclient) that includes
873 implementation of the SILC client without user interface. This
874 was major move from silc/ directory. The code has been changed
875 so that it is transparent towards the user interface. The
876 silc/ directory includes now the same user interface as before
877 and it uses the new client library. Read lib/silcclient/README.
878 Basicly, the client library performs everything else related
879 to SILC except user interface handling. Also, configuration
880 files are considered to be part of user interface and library
881 does not handle them.
883 This change also changed a lot of structures, function naming etc.
884 Most important change was that SilcClientWindow object was
885 renamed to SilcClientConnection in the client library. Created
886 also new file lib/silcclient/ops.h. Also added new files
887 silc/local_command.[ch] and silc/client_ops.[ch].
889 All these changes were made to make it easier for user interface
890 designers to create what ever user interface for the SILC client
893 It is also expected that the server will be moved to lib
894 directory as well and SILC Server Library will be created;
895 sometimes in the future.
897 * Removed Local commands from lib/silccore/silccommand.h as
898 they are application specific and new client library does not
899 handle any of those anymore.
901 * Several functions moved to lib/silcutil/silcutilc.[ch] from
902 old client implementation in silc/.
904 * Added support for callback functions in SILC_LOG_* macros.
905 Application can now set its own callbacks that will be called
906 instead of using the default functions that will always print
907 the debug messages to stderr (or stdout). Also, debugging can
908 now be disabled by setting silc_debug to FALSE and re-enabled by
909 setting it to TRUE. Note, that logging will still work even
910 if debugging is disabled.
912 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
913 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
914 silc_log_reset_debug_callbacks.
916 * To enable debugging in silc client one must give now -d
917 option on command line.
919 * Changed silc_schedule_init to automatically allocate task queues
920 if they are not allocated before calling it.
922 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Added GMP 3.1 into math library.
926 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
929 a channel in SILC network. The packet is used by servers and
930 routers to notify other routers that user has left a channel.
931 This little feature was missing until now. Added the feature
932 to protocol specification as well.
934 Added functions: silc_server_send_remove_channel_user and
935 silc_server_remove_channel_user into server.[ch].
937 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
938 lib/silccore/silcpacket.h. However, they are not implemented
941 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Fixed joining to a channel and sending channel messages
944 between server and router. The channel message sending should
945 now work inside a cell.
947 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Fixed the private message sending between server and router.
950 The private message sending should now work inside a cell.
952 * Added silc_server_replace_id into server.[ch] to replace
953 existing ID in the SILC network.
955 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
956 and silc_idlist_replace_server_id into idlist.[ch] in server.
958 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Fixed the server to server connections. Server can again now
961 connect to router. Router to router connections probably does
964 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
966 * Added dynamic protocol registering support. Now protocols can
967 registered and unregistered on the fly. Patch by cras.
969 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
971 * Added lib/contrib directory to hold routines that some platforms
972 don't have but are needed by SILC.
974 * Added getopt.c, getopt1.c and getopt.h from GNU C library
975 into lin/contrib to provide getopt() and getopt_long() for
976 those who don't have it.
978 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Added AWAY command to client. When away message is set and
981 client receives a private message packet the client automatically
982 replies to the sender with the away message.
984 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
985 bug seemed to be the cause of recent problems when compiling
988 * Added version detection support to SKE protocol specification
989 and added the new changes to the SKE implementation as well.
990 There were other minor changes in the SKE protocol as well.
992 Many changes in lib/silcske/silcske.[ch] and in
993 lib/silcske/payload.[ch].
995 * Added ^U functionality, clear input line. Patch from cras.
997 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Mainly small bugfixes on core library. Fixed some debugging
1000 logging and buffer overflow in silclog.c.
1002 * Updated config.sub and config.guess on the distribution tree.
1004 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Added command lagging support in server. Client may execute
1007 commands now only once in two seconds.
1009 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1011 * Optimized packet reception. MAC computation and checking is now
1012 also more optimized. A lot previously duplicated code is now
1013 used as generic by both client and server.
1015 * Fixed key pair generation in clientutil.c
1017 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Added into lib/silccore/silcbufutil.[ch] new function;
1020 silc_buffer_realloc.
1022 * Moved generic packet sending/encryption functions to
1023 lib/silccore/silcpacket.[ch] from client and server. Some
1024 rewriting of the functions.
1026 * Moved all generic packet reception/decryption functions to
1027 lib/silccore/silcpacket.[ch] from client and server. The
1028 packet processing is now much cleaner in both client and server.
1029 These were major changes in both client and server.
1031 * Created many common functions in server to do packet sending.
1032 Previously code were duplicated a lot, this has been removed
1035 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Rewrote major parts of the ID cache system. Don't know
1038 whether it is better now or not but at least the API is more
1041 * Major rewrite on ID cache stuff on client because of the ID
1042 cache API changes. Added idlist.c to client.
1044 * Also major rewrite on ID cache stuff on server as well.
1045 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1046 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1047 in hand, instead they are all put into the ID cache system now.
1048 All server_idlist_* routines uses ID cache now instead of
1049 traversing its own lists (those lists does not exist anymore).
1050 SilcIDList though still exists. Also, SilcXXXEntry's are
1053 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Finally made the SKE implementation compliant to the protocol
1056 specification. All mp integers are now binary encoded as
1057 opposed being HEX encoded.
1059 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1062 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1063 functions: silc_[encode/decode]_pem. Also added function
1064 silc_encode_pem_file to PEM encode with newlines ('\n') for
1067 * SILC public keys are now encoded either PEM or binary. Same
1068 option is for private keys as well. By default private keys
1069 are binary encoded and public keys PEM encoded. Silly HEX
1070 encoding were removed.
1072 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1073 function to create fingerprints.
1075 * Fixed a bug in SHA1; does not change the original data anymore.
1077 * Partly implemented INFO command on client and server side.
1078 Fixed CLEAR command. Changes to SERVER command; show current
1079 server(s) when giving command without arguments. Added
1080 VERSION command to client.
1082 * Added check to server that unregistered connections cannot
1083 execute commands (unless it is specificly allowed).
1085 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Fixed screen refresh.
1089 * Fixed channel joining bug from client. On some circumstances
1090 client tried to join to a channel it had already joined.
1092 * Added public key verification process into client's protocol.c.
1093 The client now verifies the public key from user and saves
1094 it into ~./silc/serverkeys/ directory.
1096 Added into: clientutil.[ch]: silc_client_verify_server_key.
1098 * Changed SKE protocol's silc_ske_initiator_finish function
1099 to accept callback function that verifies the received public
1100 key. Removed old silc_ske_verify_public_key function.
1102 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1105 silc_pkcs_private_key[_data]_set.
1107 * Made the password and public authentication more cleaner in
1108 server's protocol.c.
1110 * Removed historic and obsolete protocol `channel_auth' from
1111 both client and server.
1113 * Removed wrong way of sending command status messages from
1114 server to client in server's command.c. The old way violated
1115 protocol specification.
1117 Changes to silccore/silccommand.[ch]: removed
1118 silc_command_encode_status_payload -> not needed anymore,
1119 changed silc_command_encode_payload_va to accept extra
1120 argument on variable argument list. The argument type must
1121 now be provided to the function. Also, added new function:
1122 silc_command_encode_reply_payload_va which is same as
1123 normal command_encode_payload_va except command status type
1124 is provided as extra argument.
1126 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Added ~./silc directory handling. The directory includes the
1129 public and private keys for the client.
1131 Added silc_client_check_silc_dir, silc_client_create_identifier
1132 and silc_client_load_keys.
1134 * Implemented SILC protocol compliant public key. Added public
1135 and private key saving to and loading from files.
1137 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1138 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1139 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1140 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1141 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1143 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1144 silc_pkcs_load_[public/private]_key.
1146 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Added silc_server_get_route (route.[ch]) to get connection
1149 data for the fastest route for given ID.
1151 * Implemented INVITE command on client and server. The command
1152 were re-defined in the SILC Protocol Specification and the
1153 implementation now complies with the specification.
1155 * Implemented PING command on client and server.
1157 * Implemented NAMES command on client and server. The server side
