3 * Oops, a little mistake in server's connection authentication
4 protocol. The protocol is not ended with FAILURE but with
5 SUCCESS if the authentication is Ok. :) Affected file is
8 * Implemented NICK_CHANGE notify handling in server in the file
9 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
10 the local clients on the channel. After the changing nickname
11 in router environment snhould work and the [<unknown>] nickname
12 should appear no more.
14 The silc_server_replace_id function that receives the Replace ID
15 payload now sends the NICK_CHANGE notify type also in the file
16 silcd/packet_receive.c
18 * Changed WHOIS and IDENTIFY command to support the maximum amount
19 of arguments defined in protocol specs (3328 arguments). This
20 fixed a bug that caused problems when there were more than three
23 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Added extra parameter, command identifier, to the
26 silc_client_send_command so that explicit command identifier
29 Changed that ID list routines uses specific command identifier
30 when sending WHOIS/IDENTIFY requests to the server so that they
31 can be identified when the reply comes back.
33 Affected files lib/silcclient/command.[ch],
34 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
36 * Added `sender' argument to silc_server_packet_send_to_channel
37 to indicaet the sender who originally sent the packet to us
38 that we are now re-sending. Ignored if NULL. Affected file
39 silcd/packet_send.[ch].
41 * Added some server statistics support in silcd/server_internal.h
42 SilcServerStatistics structure and around the server code. Also
43 send some nice statistics information when client is connecting
46 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Fixed channel ID decoding in server's JOIN command reply in
51 * Fixed braodcasting of replace ID payload to not to send it if
52 we are standalone server in silcd/packet_receive.c.
54 * Fixed all channel message sending routines to not to send
55 packets to clients that has router set, since they are routed
56 separately in the same function earlier. Affects file
57 silcd/packet_send.c and all channel packet sending functions.
59 * In USERS reply, res_argv[i] are not allocated, the table
60 is allocated. Thus changed that free the table, not its
63 * In server's whois_check and identify_check if the client is
64 locally connected do not send any WHOIS commands - they are not
67 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
69 * Fixed some minor bugs in client when sending WHOIS command. The
70 arguments was in wrong order.
72 * Removed statis function add_to_channel from server in
73 silcd/command.c that was previously used with the joining but
76 * Tested USERS command in router environment successfully with two
77 routers, two servers and two clients.
79 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Reorganized the USERS command and command reply in client library
82 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
83 When the command is given by user we register a pending command
84 callback that will reprocess the command after the reply has been
85 received from the server. When reprocessing the packet we then
86 display the information. Thus, the USERS information is displayed
87 now in the command callback instead of in the command reply
88 callback. The processing of the command is same as previously
89 when server has sent the command reply in the JOINing process.
91 * Added to USERS command in silcd/command_reply.c to join the client,
92 we didn't use to know about, to the channel after we've created
93 a client entry for it. Also, for clienet we did know already still
94 check whether it is on the channel or not and add it if not.
96 * Removed silc_server_command_join_notify as the function and its
99 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Changed the client's pending command handling to the same as the
102 server's pending command handling. It is also now possible to
103 execute command reply functions from other command reply
104 function as the function callbacks for commands and command
105 replies are one and same. The pending commands are not static
106 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
107 in client connection context. Thus, pending commands are server
108 connection specific as it is convenient.
110 Changed the function silc_client_command_pending and
111 silc_client_command_pending_del and added new function
112 silc_client_command_pending_check. Removed the
113 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
116 * Added cmd_ident, current command identifier, to the client
117 connection context in lib/silcclient/client.h to keep track on
118 command identifiers used in command sending. Client's command reply
119 function handling now supports the mandatory command identifiers.
121 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
122 funtions in client to fully support pending command callbacks.
124 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
125 as one of the arguments to the application in the command reply
128 * NOTE: The FORWARDED flag is depracated. It used to be depracated
129 before first releasing SILC but came back. Now it is removed again
130 and should come back nomore. The FORWARDED flag was used only
131 by the JOINing procedure by forwarding the command packet to router.
132 Now, the JOINing procedure has been changed to more generic (due
133 to various router environment issues) and FORWARDED is not needed
134 anymore for anything. The protocol specification is yet to be
137 Now, removed silc_server_packet_forward from server and the flag
138 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
140 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
142 * Renamed NAMES command to USERS command. The NAMES was named that
143 due to historical reasons. Now it is renamed. Also, rewrote
144 parts of the USERS command. The nickname list is not sent anymore
145 by the server. Only Client ID and mode lists are sent in the USERS
146 command. Changed this also to the protocol specification.
148 The client now resolves the names and stuff after it receives
149 the USERS list from the server when joining to the channel.
151 * WHOIS and IDENTIFY commands has been changed to support multiple
152 Client ID's per command. One can now search for multiple users
153 in the network by sending only one WHOIS or IDENTIFY command.
154 Changed the code and the protocol specifications.
156 * Removed silc_server_command_identify_parse and changed that IDENTIFY
157 uses silc_server_command_whois_parse to parse the request. */
159 * If normal server, do not parse the WHOIS and IDENTIFY requests
160 before sending it to the router. Saves some time.
162 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * Fixed JOIN command on client library. Wrong number of arguments
165 used to crash the client.
167 * Added silc_server_channel_has_global function to check whether
168 channel has global users or not.
170 * Added silc_server_channel_has_local function to check whether channel
171 has locally connected clients on the channel.
173 * The silc_server_remove_from_one_channel now checks whether the
174 channel has global users or not after given client was removed from
175 the channel. It also checks whether the channel has local clients
176 on the channel anymore. If it does not have then the channel entry
177 is removed as it is not needed anymore.
179 * The silc_server_notify now checks on JOIN notify whether the joining
180 client is one of locally connected or global. If it is global then
181 the channel has now global users on the channel and that is marked
182 to the channel entry. Also, it now saves the global client to
183 global list who is joining and JOINs it to the channel. This is
184 for normal server, that is.
186 Changed silc_server_send_notify_on_channel,
187 silc_server_packet_relay_to_channel and
188 silc_server_packet_send_to_channel check if we are normal server
189 and client has router set (ie. global client) do not send the
190 message to that client, as it is already routed to our router.
192 * Implemented LEAVE notify type handling in silc_server_notify
195 * Tested LEAVE command in router environment successfully. Tested
196 with two routers, two servers and two clients.
200 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
202 * Implemented SIGNOFF notify type handling in silc_server_notify
205 * silc_server_remove_id now removes the client entry from all channels
206 it has joined and thusly sends SIGNOFF notify type.
208 * Rewrote the NAMES list generation in server by removing two excess
209 loops. The lists are created now inside one loop.
211 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * silc_server_remove_channel_user checks now also global list
214 for channel and client.
216 * silc_server_new_channel_user checks now both local and global
217 list for channel and client. Fixed a bug in client id decoding.
218 Used to decode wrong buffer.
220 * silc_server_channel_message checks now both local and global
221 list for channel entry.
223 * Tested channel joining (hence JOIN) in router environment
224 successfully. Tested with two routers, two servers and two
227 * Tested channel message sending in router environment successfully.
229 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Added silc_server_save_channel_key into server.[ch] to save the
232 received channel key in Channel Key payload processing. It is
233 also used in JOIN command reply handling.
235 Equivalent function silc_client_save_channel_key added into
236 client.[ch] into client library.
238 * Changed JOIN command reply to send information whether the channel
239 was created or not (is existing already) and the channel key
240 payload. Changed protocol specs accordingly.
242 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
243 the request was sent by ID and not by nickname. Crashed on
246 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
248 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
249 now correctly save the received data.
251 * silc_server_free_sock_user_data now notifies routers in the
252 network about entities leaving the network.
254 At the same time implemented functions silc_server_remove_id
255 and silc_server_send_remove_id to receive and send REMOVE_ID
256 packets. The packet is used to notify routers in the network
257 about leaving entities. The ID removed will become invalid in
260 * Added function silc_idlist_del_server into server. Removes and
261 free's server entry from ID list.
263 * silc_server_private_message function now checks, if we are router,
264 that the destination ID really is valid ID, naturally.
266 * In router when NEW_ID packet is received (for new client) the
267 hash of the Client ID is saved in the ID Cache but the
268 client->nickname is set to NULL, instead of putting the hash
271 IDENTIFY command now also checks that client->nickname must be
272 valid. If it is not if will request the data from the server who
273 owns the client. Added new function
274 silc_server_command_identify_check.
276 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
277 to set the command to already allocated Command Payload.
279 * Tested private message sending in router environment with two
280 routers, two servers and two clients. Fixed minor bugs and now
283 * Fixed segfault from client's NAMES command. Used to crash if
286 * Forwarded packets must not be routed even if it is not destined
287 to the receiver. Changed server code comply with this.
289 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Added `require_reverse_mapping' boolean value to ServerParams
292 structure. If TRUE (not default) the server will require that
293 the connecting host has fully qualified domain name.
295 If the reverse mapping is not required and hostname could not be
296 found the IP address is used as hostname.
298 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Implemented version string checking to both client and server.
301 The check is incomplete currently due to the abnormal version
302 strings used in development version of SILC.
304 * Changed all command functions in server to use the new
307 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Changed char *data to unsigned char *data in ID Cache system to
310 support binary data as ID Cache data. Changed code to support
311 binary data in lib/silccore/idcache.c.
313 * Renamed silc_server_packet_relay_command_reply to
314 silc_server_command_reply as it is normal packet receiving
315 function. Rewrote the function to accept command replys for
316 servers and not only for clients.
318 * Mark remote router always as registered server if we are connecting
319 to it. Otherwise, commands sent by the router to us are ignored.
321 * All ID List find routines now returns the ID Cache Entry pointer
322 as well if requested.
324 * WHOIS command works now in router environment, tested with two
325 routers, two servers and two clients.
327 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
328 in router environment (as it is almost equivalent to WHOIS) but
329 hasn't been tested thoroughly. Added new functions:
331 silc_server_command_identify_parse
332 silc_server_command_identify_send_reply
333 silc_server_command_identify_from_client
334 silc_server_command_identify_from_server
336 * Disabled route cache adding because adding two different ID's with
337 same IP replaces the old cache entry thus giving wrong route.
338 The entry->router->connection is always the fastest route anyway
339 so route cache may not be needed. Of course, new routes maybe
340 established after receiving the ID when the entry->router->connection
341 might not be anymore the most optimal.
343 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Add route cache for received ID for fast routing.
347 * Added silc_server_packet_route to route received packet on router
348 that is not destined to us.
350 * Renamed silc_server_get_route to silc_server_route_get.
352 * Added id_string and id_string_len fields into SilcServer to
353 include encoded ServerID for fast comparing without excess
354 encoding of the ID's.
356 * Cleaned up WHOIS command on server side. Added following static
359 silc_server_command_whois_parse
360 silc_server_command_whois_check
361 silc_server_command_whois_send_reply
362 silc_server_command_whois_from_client
363 silc_server_command_whois_from_server
365 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
366 arguments in command replies. All command functions should be
367 updated to use this macro.
369 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
371 * Minor typo fixes on command reply handling on server.
373 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Added silc_server_command_add_to_channel internal routine to add
376 the client to the channel after router has created the channel and
377 sent command reply to the server.
379 * Added generic silc_server_send_command to send any command from
382 * Use static buffer with ID rendering instead of duplicating data.
384 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * Fixed a channel user mode bug when joining to a channel server gave
387 everybody channel founder rights, oops.
389 * We mark ourselves as the router of the incoming server connection
390 if we are router ourselves. This way we can check in some packet
391 sending functions whether it is locally connected server. For
392 incoming router connections we put NULL.
394 * For router sending packets locally means now always sending the
395 packet cell wide; to local clients and local servers. For normal
396 server sending packet locally means sending it to only local
399 * Fixed the JOIN command to really work in router environment. If the
400 channel is created it is always created by the router. Router is
401 also responsible of making the initial joining to the channel,
402 sending JOIN notify to the sending server and distributing
403 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
404 does not exist server doesn't do anything else but forward the
405 command to the router which performs everything.
407 * Added silc_server_send_channel_key function to send the Channel Key
410 * Added silc_server_create_channel_key to create new channel key. The
411 channel key is now re-generated everytime someone joins or leaves
412 a channel, as protocol dictates. Note: channel->key_len is the
415 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Splitted server.[ch] finally. Created now packet_send.[ch] and
418 packet_receive.[ch] to separate packet sending and receiving
419 routines. The server.[ch] now includes everything else including
420 actual packet processing (writing and reading data) and other
423 Renamed silc_server_private_message_send_internal to
424 silc_server_send_private_message. The routine is still though
425 used only to relay private messages as server does not send
426 private messages itself.
428 Renamed silc_server_new_channel to silc_server_create_new_channel
429 and added new function sicl_server_new_channel that handles the
430 incoming New Channel packet. Added also new sending function
431 silc_server_send_new_channel to send New Channel Payload.
433 * Added new function silc_server_notify to process incoming notify
434 packet to the server/router. Server may then relay the notify
435 to clients if needed.
437 * Added new function silc_server_new_channel_user to process incoming
438 New Channel User packet. Router will redistribute the packet and
439 send JOIN notify to its local clients and locally connected servers
440 if needed. Normal server will send JOIN notify to its local client
441 on same channel when received this packet. Added also corresponding
442 sending function silc_server_send_new_channel_user to sent the
445 * Added boolean route argument to send_notif_to_channel and
446 packet_send_to_channel functions to attempt to route the packet
447 if it is TRUE and send only locally if it is FALSE.
449 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * silc_server_replace_id now broadcasts the received replace ID
452 packet if it is not broadcast packet already. The router must
453 broadcast to inform other routers about changed ID.
455 * Added backpointer to server's router into SilcServer context in
456 silcd/server_internal.h.
458 * Fixed silc_server_packet_broadcast to send correct broadcast
461 * The channel key is now distributed to the local client as soon
462 as it is received from the router (in router environment) so that
463 no other packet may be sent for the channel until client has
466 * silc_server_remove_channel_user now broadcasts the received
467 Remove Channel User packet if it is not broadcast packet already.
468 The router must broadcast to inform other routers about removed
471 * Added users field into SilcPacketContext that is a reference count
472 of the context. One can increase the reference count by calling
473 silc_packet_context_dup which is now changed to just increase the
474 reference count instead of duplicating the data. The reference
475 count is decresed by calling silc_packet_context_free that will
476 free the data after the reference count hits zero.
478 For now on the packet context and everything allocated into it
479 (including the raw packet from network) must be freed by calling
480 the new silc_packet_context_free function. Added also new function
481 silc_packet_context_alloc that must be used now to allocate the
482 context. This also means that if a routine is asynchronous from
483 silc_[client/server]_packet_parse_type the packet context must
484 be duplicated by calling silc_packet_context_dup. Otherwise it
485 gets free'd after silc_[client/server]_packet_parse_type returns.
486 Also, one must remember that if packet is duplicated then its
487 reference count must be decresed by calling the free function as
488 many times as it was duplicated.
490 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
491 from both client and server.
493 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
495 * Made joining to a channel working in router environment.
497 * Cleaned up JOIN command on server side and create function
498 silc_server_command_join_channel internal routine to make the
501 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Changed silc_command_pending list to SilcDList. Also, added
504 `ident' field to SilcServerCommandPending structure to identify
505 the reply and to call correct callback.
507 Added silc_server_command_pending_check function to replace the
508 corresnponding macro. The silc_command_pending list is not
511 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
512 to set identifier to previously allocated Command Payload. It
513 is used to set identifier for command when resending Command
516 * Added silc_command_payload_encode_payload to encode Command
517 Payload buffer from SilcCommandPayload structure.
519 * Added silc_argument_payload_encode_payload to encode Argument
520 payload buffer from SilcArgumentPayload structure.
522 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
524 * Changed WHOIS command to support router connection on server side.
525 The whois request is always sent to router unless the server is
526 standalone server. After server has received the reply from the
527 router will it send the reply to the client.
529 * Added silc_server_packet_broadcast into silcd/server.[ch] to
530 broadcast received broadcast packet. The function is used only
531 by router. The broadcast packet is always sent to the router's
534 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
535 render given ID to printable string, for log files for example.
537 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
539 * Made basic router to router connections working. At least they
540 can now connect to each other but nothing really works the way
541 they are supposed - yet.
543 * Added new initiator token to RouterConnection configuration
544 file in silcd/serverconfig.[ch]. It is used to tell whether we
545 are the initiator to the remote router or whether we'll expect
546 the other end to connect.
548 * Moved registering of listener task to silc_server_init, hence
549 the server starts listenning as soon as it is run, even if it
550 does not have connections to other routers. Let's see how well
553 * Changed default connection retry timeouts for more suitable in
556 * Removed cipher and such arguments from silc_idlist_add_client
557 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
558 Added new function silc_idlist_add_data to add the keys and stuff
561 * Added SilcIDListData structure and added it to SilcClientEntry
562 and SilcServerEntry as their first field in the structure. This
563 way we can explicitly cast the ID entries to the SilcIDListData
564 structure and get common data for the entries. In past, we had
565 to first check what type of connection it is and then cast it to
566 correct ID entry type. Now, we can directly cast the opaque
567 pointer to the SilcIDListData (no matter what ID entry it actually
568 is) and get the data needed.
570 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Wow, found a bug in scheduler. The scheduler uninitialized itself
573 in some circumstances even if threre were timeout tasks, though not
574 IO tasks, but tasks anyway. Now fixed.
576 * Defined SilcServerConnection structure to hold connection specific
577 stuff about directly connected servers and routers. The definition
578 is currently in silcd/server_internal.h. I thought about having
579 a bit more important role fro this struct but for now it is used
580 only when connecting to other server (or router actually).
582 * Added connecting retry support in server when connecting to
583 router(s). The retry feature implement exponential backoff
584 algorithm. Also, added SilcServerParams structure to hold default
585 parameters for server. For now, it include these retry settings
586 and are hard coded. After server is moded to be as Silc Server
587 Library this structure will be more important.
589 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Changed client librarys channel->clients table to SilcList and
592 changed code accordingly.
594 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Changed client's channel table to SilcList and changed code
597 accordingly. Also changed SilcChannelClientEntry to include back-
598 pointer to the channel so that client entry can use that structure
599 as list as well and we have fast cross-reference to the channel.
600 This change dramatically decreased the complexity of channel
601 handling with client entry and vice versa (removed one extra
602 loop when searching for channel entry from many functions).
604 * Changed server->sim from table to SilcDList and changed code
607 * NAMES command can now be used from user interface. It will show
608 the user list on the channel, neatly.
610 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
611 Code now saves realname of the user if it becomes available.
613 * Renamed configure.in to configure.in.pre and made ./prepare
614 script to automatically add correct version string to
615 configure.in which it creates from configure.in.pre.
617 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * NAMES command reply now shows users mode with the nickname when
622 * Moved silc_client_ch[u]mode[_char] functions from
623 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
624 place sucks, they are utility functions and should be in some
627 * Fixed some unsigned int's to unsigned short's. Patch by cras.
629 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
632 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
636 * Added TRQ (efficient deque and list library) into lib/trq. This is
637 a very good list library that is currently used in the SILC. Defined
638 SilcList API over the library because I didn't like the API very
639 much. See lib/trq/silclist.h for the API and examples of how to
640 use the API. Fixed various places in the code to use the new
641 SilcList API. The SilcList is meant for lists that has a structure
642 already defined as a list. It is not suitable to add just some
643 context to the list (in TRQ, the context is the list actually).
645 So, I defined SilcDList that can be used for the purpose where
646 predefined list structure does not exit. This can be used as
647 such list. Now some context just can be added to the SilcDList.
648 Currently this list is not used in the SILC just yet, though there
649 are a lot places where this can replace dynamically allocated
650 tables and I will fix these places, later, to use SilcDList.
651 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
652 and use TRQ internally).
654 Also fixed some annoying warning messages that the original TRQ
655 code generated. Also minor changes to TRQ's Makefile.in.
657 * Added support for querying by Client ID to both WHOIS and
658 IDENTIFY commands into server, as required by the protocol.
660 * Removed method function pointers from SilcBuffer structure. They
661 weren't used to anything and just increased the context size for
662 no good reason. This change also made silc_buffer_alloc and
663 silc_buffer_free functions inline functions.
665 * Disabled command flooding detection support until it's fixed so
666 that it accepts commands in but does not execute them more than once
669 * Added silc_net_localhost(), to return local hostname, into
670 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
671 that must be initialized before calling silc_client_init.
673 * Added new function: silc_server_send_notify_on_channels to send
674 notify messages to all channels client has joined. It is assured
675 that the message is sent only once per client.
677 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
678 lib/silcutil/silcutil.[ch] as silc_format function. The new
679 function is generic and is used by server as well, not only by
680 the logging routines.
682 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
683 the provided version string was not acceptable. Added new function:
684 silc_ske_check_version into lib/silcske/silcske.h. The function
685 must be implemented by the application (client or server) and it
686 does not reside in the SKE library. The function checks the version
687 string remote end sent.
689 * Added back pointers (to opaque context and to SilcSocketConnection)
690 into SilcPacketContext structure into lib/silccore/silcpacket.h.
692 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
693 duplicate packet context structure.
695 * Changed `notify' client operation to send same arguments as client
696 receives from server except for ID's. ID's are mapped to correct
697 ID entry and that is returned. Also, if channel entry is not sent
698 by server but the notify is for channel the channel entry is sent
699 to application (otherwise application doesn't know that it is for
700 channel (library gets it from packet's Destination ID)).
702 * Added silc_client_remove_from_channels into client library to
703 remove a client from all channels it has joined to. Used when
704 received SIGNOFF notify from server. Added also new function
705 silc_client_replace_from_channels to replace old ID entry with
706 new ID entry on all channels. Used when received NICK_CHANGE
709 * Fixed ID Cache list handling in silc_idlist_get_client in
710 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
711 to get (or query) client by ID.
715 * Added connection authentication status message defined by the
716 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
717 support for these into the code in client and server side.
719 * Added generic function silc_client_send_command to send any command
720 with variable argument list. Application should use this function
721 to send commands if the command functions provided by the library
722 does not suite for the application's user interface needs.
724 * Added new `failure' client operation. Application is notified about
725 received failure packet if client is executing a protocol. In this
726 case the protocol's execution has failed.
728 * Added SKE's end notify to send the SKE_SUCCESS notify message that
729 is required by the protocol.
731 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
732 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
735 * Added status flag to SilcSKE object to indicate realtime status
738 * Application receives now exactly same command reply arguments as
739 the library receives from server. However, if ID is received the
740 corresponding ID entry is returned to the application (eg. Client
741 ID is mapped to correct SilcClientEntry entry and that is returned).
742 Changed command_reply client operation due to this change.
744 * Changed all ID's in commands and in command replys as ID Payloads.
745 Change affected both client and server side codes.
747 All ID's sent in SILC network (with execption of ID's in SILC
748 Packet header) are sent in ID Payload to support variable length
751 * Server now notifies nick changes and notifies all clients on
752 the channels about the new nickname (about the new Client ID,
755 * Implemented CMODE command to change channel modes. Supports all
756 channel modes defined by the protocol specs except ban and invite
757 lists. (Also, private channel key mode is supported but support for
758 setting private channel key in client is missing, thus, this mode
759 has no effect on client side (except that server requires that the
760 client uses private channel key and normal channel traffic does not
763 Also, invite mode works per se, but INVITE command does not work
764 yet correctly, so you can set channel as invite only channel but
765 inviting clients to the channel does not work (it is yet to be
766 thought what's the best way to do it).
768 * Added new command SILC_COMMAND_CUMODE to change user mode on the
769 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
770 Implemented CUMODE command to change user's mode on the channel.
771 Supports all modes defined by the protocol specs.
773 * Added NAMES command reply to return users modes on the channel.
775 * Removed unnecessary and slow ciphers from lib/silccrypt.
777 * Set SO_KEEPALIVE option to connection sockets by default.
779 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
781 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
782 redefined the Notify Payload into protocol specs.
784 * Added silc_id_payload_parse_id to get ID directly from raw
787 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
790 accept searching by Client ID as well.
792 * Added support for LEAVE and SIGNOFF notify types in client library.
794 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
795 to parse ID Payload from raw data.
797 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Added flags parameter into silc_ske_assemble_security_properties
800 function in lib/silcske/silcske.[ch].
802 * Changed notify client operation to fit better for notify messages
803 sent by server. The notify payload received from server is now
804 passed to the application (after parsing it to SilcNotifyPayload).
805 It is application's responsibility to retrieve the arguments
806 from the payload and show the message the way it wants. The message
807 sent by server is implementation specific.
809 * Changed public keys to comply with the protocol specification.
810 Old public keys are not supported anymore and are not compatible.
812 * Removed nickname from Channel Payload as the latest draft removed
813 it. The client must resolve the nickname from the NAMES command
814 reply received when it joined the channel.
816 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
818 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Fixed some errors in protocol specification drafts.
822 * Created lib/silccore/silcnotify.c to implement Notify Payload
823 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
824 generic payloads described by protocol specifications. The file
825 includes implementations for ID Payload and Argument Payload.
827 * Changed Command Payload implementation to use the new Argument
828 Payload. Changed command_xxxx_payload to command_payload_xxxx
829 to comply with SILC coding conventions.
831 * Added suppport for Argument Payload handling in Notify Payload
832 implementation as protocol requires it. Added the new support
833 into server and client lib as well.
835 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
837 * Added support for multiple nicknames on same channel. [n] is
838 added locally to the nickname if there are more than one same
839 nicknames on the channel.
841 * Server now sends all nicknames that matched WHOIS request.
842 Client also shows the list received from server.
844 * Added TOPIC command to client side. User can now set and show
845 current topic on channel.
847 * Added MOTD command to client and server. Also, server sends the
848 motd when client connects to the server.
850 * Changed version strings to comply ISO 8601.
852 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Fixed protocol error handling in client library. It should now
855 cope even if the SKE fails for some reason.
857 * Made new protocol specification drafts for submitting to IETF.
859 * Implemented TOPIC command to server in silcd/command.c.
861 * Added two new notify types into lib/silccore/silcnotify.h:
862 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
863 notify nickname change and topic setting/change on a channel.
865 * API change of command_reply operation in client library. The
866 application gets now the status type received from server as well.
868 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Removed the function just added to lib/silcutil/silcschedule.[ch].
872 * Cras fixed and optimized the packet handling even further and
873 it should work now. Minor change to the prototype of function
874 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
876 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
878 * Added new function into lib/silcutil/silcschedule.[ch]:
879 silc_schedule_with_fd to select() a specified fd. The function
880 returns after timeout expires or data arrives or goes. The
881 function is used by packet routines to wait that all data is
882 received from network.
884 * Fixed data reading from network in lib/silccore/silcpacket.c.
885 The code now assures that all data is read from the fd and then
886 continues packet processing. This was a bug fix since the code
887 used to drop some data in some circumstances.
889 * Added new function into lib/silcclient/client.[ch]:
890 silc_client_start_key_exchange to start key exchange after
891 connection has been established to server. The code internally
892 now uses this funtion but its main purpose was to provide it
893 for applications that perform their own connecting. After
894 application has created a connection it merely calls this
895 function to start the key exchange between client and server.
896 The library takes care of everything else after that.
898 Updated also lib/silcclient/README to explain the usage of
901 * Do not send to application information that connection has
902 been established. Application gets notified it by connect
905 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Applied cras's patch to add silc_schedule_one function. The
908 function runs scheduler once and returns.
910 * Fixed the scheduler after cras messed it up. The timeout
911 handling works now as it's supposed to work.
913 * Added into lib/silccore/ silcnotify.h to include notify
914 message types support. Changed silc_server_send_notify*
915 functions, in server.[ch], to support those new notify types.
916 Added the support for the notify types into client library,
917 as well. Added new notify client operation into ops.h in
920 * Changed silc_server_packet_send_to_channel to send normal
921 packets instead of just channel message packets. The function
922 is now used to send the notify packets to channels. It is not
923 used to send channel message packets anymore, as server never
926 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
927 va_arg()s as it seems to require it nowadays. I guess, if SILC
928 is compiled with older va_arg() the new code should work anyway.
930 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Splitted core library. Core library (lib/silccore) includes
933 now only SILC protocol specific core (and common) components.
934 Created new utility library (lib/silcutil) that includes more
935 generic purpose stuff. The stuff for util library was taken
936 from the old core library. This was minor and easy split.
938 * Created SILC Client Library (lib/silcclient) that includes
939 implementation of the SILC client without user interface. This
940 was major move from silc/ directory. The code has been changed
941 so that it is transparent towards the user interface. The
942 silc/ directory includes now the same user interface as before
943 and it uses the new client library. Read lib/silcclient/README.
944 Basicly, the client library performs everything else related
945 to SILC except user interface handling. Also, configuration
946 files are considered to be part of user interface and library
947 does not handle them.
949 This change also changed a lot of structures, function naming etc.
950 Most important change was that SilcClientWindow object was
951 renamed to SilcClientConnection in the client library. Created
952 also new file lib/silcclient/ops.h. Also added new files
953 silc/local_command.[ch] and silc/client_ops.[ch].
955 All these changes were made to make it easier for user interface
956 designers to create what ever user interface for the SILC client
959 It is also expected that the server will be moved to lib
960 directory as well and SILC Server Library will be created;
961 sometimes in the future.
963 * Removed Local commands from lib/silccore/silccommand.h as
964 they are application specific and new client library does not
965 handle any of those anymore.
967 * Several functions moved to lib/silcutil/silcutilc.[ch] from
968 old client implementation in silc/.
970 * Added support for callback functions in SILC_LOG_* macros.
971 Application can now set its own callbacks that will be called
972 instead of using the default functions that will always print
973 the debug messages to stderr (or stdout). Also, debugging can
974 now be disabled by setting silc_debug to FALSE and re-enabled by
975 setting it to TRUE. Note, that logging will still work even
976 if debugging is disabled.
978 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
979 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
980 silc_log_reset_debug_callbacks.
982 * To enable debugging in silc client one must give now -d
983 option on command line.
985 * Changed silc_schedule_init to automatically allocate task queues
986 if they are not allocated before calling it.
988 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
990 * Added GMP 3.1 into math library.
992 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
994 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
995 a channel in SILC network. The packet is used by servers and
996 routers to notify other routers that user has left a channel.
997 This little feature was missing until now. Added the feature
998 to protocol specification as well.
1000 Added functions: silc_server_send_remove_channel_user and
1001 silc_server_remove_channel_user into server.[ch].
1003 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1004 lib/silccore/silcpacket.h. However, they are not implemented
1007 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Fixed joining to a channel and sending channel messages
1010 between server and router. The channel message sending should
1011 now work inside a cell.
1013 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Fixed the private message sending between server and router.
1016 The private message sending should now work inside a cell.
1018 * Added silc_server_replace_id into server.[ch] to replace
1019 existing ID in the SILC network.
1021 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1022 and silc_idlist_replace_server_id into idlist.[ch] in server.
1024 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Fixed the server to server connections. Server can again now
1027 connect to router. Router to router connections probably does
1030 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Added dynamic protocol registering support. Now protocols can
1033 registered and unregistered on the fly. Patch by cras.
1035 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Added lib/contrib directory to hold routines that some platforms
1038 don't have but are needed by SILC.
1040 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1041 into lin/contrib to provide getopt() and getopt_long() for
1042 those who don't have it.
1044 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1046 * Added AWAY command to client. When away message is set and
1047 client receives a private message packet the client automatically
1048 replies to the sender with the away message.
1050 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1051 bug seemed to be the cause of recent problems when compiling
1054 * Added version detection support to SKE protocol specification
1055 and added the new changes to the SKE implementation as well.
1056 There were other minor changes in the SKE protocol as well.
1058 Many changes in lib/silcske/silcske.[ch] and in
1059 lib/silcske/payload.[ch].
1061 * Added ^U functionality, clear input line. Patch from cras.
1063 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1065 * Mainly small bugfixes on core library. Fixed some debugging
1066 logging and buffer overflow in silclog.c.
1068 * Updated config.sub and config.guess on the distribution tree.
1070 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1072 * Added command lagging support in server. Client may execute
1073 commands now only once in two seconds.
1075 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Optimized packet reception. MAC computation and checking is now
1078 also more optimized. A lot previously duplicated code is now
1079 used as generic by both client and server.
1081 * Fixed key pair generation in clientutil.c
1083 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Added into lib/silccore/silcbufutil.[ch] new function;
1086 silc_buffer_realloc.
1088 * Moved generic packet sending/encryption functions to
1089 lib/silccore/silcpacket.[ch] from client and server. Some
1090 rewriting of the functions.
1092 * Moved all generic packet reception/decryption functions to
1093 lib/silccore/silcpacket.[ch] from client and server. The
1094 packet processing is now much cleaner in both client and server.
1095 These were major changes in both client and server.
1097 * Created many common functions in server to do packet sending.
1098 Previously code were duplicated a lot, this has been removed
1101 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1103 * Rewrote major parts of the ID cache system. Don't know
1104 whether it is better now or not but at least the API is more
1107 * Major rewrite on ID cache stuff on client because of the ID
1108 cache API changes. Added idlist.c to client.
1110 * Also major rewrite on ID cache stuff on server as well.
1111 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1112 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1113 in hand, instead they are all put into the ID cache system now.
1114 All server_idlist_* routines uses ID cache now instead of
1115 traversing its own lists (those lists does not exist anymore).
1116 SilcIDList though still exists. Also, SilcXXXEntry's are
1119 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Finally made the SKE implementation compliant to the protocol
1122 specification. All mp integers are now binary encoded as
1123 opposed being HEX encoded.
1125 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1128 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1129 functions: silc_[encode/decode]_pem. Also added function
1130 silc_encode_pem_file to PEM encode with newlines ('\n') for
1133 * SILC public keys are now encoded either PEM or binary. Same
1134 option is for private keys as well. By default private keys
1135 are binary encoded and public keys PEM encoded. Silly HEX
1136 encoding were removed.
1138 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1139 function to create fingerprints.
1141 * Fixed a bug in SHA1; does not change the original data anymore.
1143 * Partly implemented INFO command on client and server side.
1144 Fixed CLEAR command. Changes to SERVER command; show current
1145 server(s) when giving command without arguments. Added
1146 VERSION command to client.
1148 * Added check to server that unregistered connections cannot
1149 execute commands (unless it is specificly allowed).
1151 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1153 * Fixed screen refresh.
1155 * Fixed channel joining bug from client. On some circumstances
1156 client tried to join to a channel it had already joined.
1158 * Added public key verification process into client's protocol.c.
1159 The client now verifies the public key from user and saves
1160 it into ~./silc/serverkeys/ directory.
1162 Added into: clientutil.[ch]: silc_client_verify_server_key.
1164 * Changed SKE protocol's silc_ske_initiator_finish function
1165 to accept callback function that verifies the received public
1166 key. Removed old silc_ske_verify_public_key function.
1168 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1171 silc_pkcs_private_key[_data]_set.
1173 * Made the password and public authentication more cleaner in
1174 server's protocol.c.
1176 * Removed historic and obsolete protocol `channel_auth' from
1177 both client and server.
1179 * Removed wrong way of sending command status messages from
1180 server to client in server's command.c. The old way violated
1181 protocol specification.
1183 Changes to silccore/silccommand.[ch]: removed
1184 silc_command_encode_status_payload -> not needed anymore,
1185 changed silc_command_encode_payload_va to accept extra
1186 argument on variable argument list. The argument type must
1187 now be provided to the function. Also, added new function:
1188 silc_command_encode_reply_payload_va which is same as
1189 normal command_encode_payload_va except command status type
1190 is provided as extra argument.
1192 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1194 * Added ~./silc directory handling. The directory includes the
1195 public and private keys for the client.
1197 Added silc_client_check_silc_dir, silc_client_create_identifier
1198 and silc_client_load_keys.
1200 * Implemented SILC protocol compliant public key. Added public
1201 and private key saving to and loading from files.
1203 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1204 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1205 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1206 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1207 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1209 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1210 silc_pkcs_load_[public/private]_key.
1212 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * Added silc_server_get_route (route.[ch]) to get connection
1215 data for the fastest route for given ID.
1217 * Implemented INVITE command on client and server. The command
1218 were re-defined in the SILC Protocol Specification and the
1219 implementation now complies with the specification.
1221 * Implemented PING command on client and server.
1223 * Implemented NAMES command on client and server. The server side
1224 supports currently only normal server not router server yet.
1225 Some changes to NAMES definition in SILC protocol specification.
1227 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Implemented LEAVE command on client and server.
1231 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1232 again. This change was made to the protocol as well. Server
1233 should not violate the protocol specification anymore.
1235 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1238 was tested. SOCKS4 was not but should work anyway.
