3 * Fixed channel ID decoding in server's JOIN command reply in
6 * Fixed braodcasting of replace ID payload to not to send it if
7 we are standalone server in silcd/packet_receive.c.
9 * Fixed all channel message sending routines to not to send
10 packets to clients that has router set, since they are routed
11 separately in the same function earlier. Affects file
12 silcd/packet_send.c and all channel packet sending functions.
14 * In USERS reply, res_argv[i] are not allocated, the table
15 is allocated. Thus changed that free the table, not its
18 * In server's whois_check and identify_check if the client is
19 locally connected do not send any WHOIS commands - they are not
22 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Fixed some minor bugs in client when sending WHOIS command. The
25 arguments was in wrong order.
27 * Removed statis function add_to_channel from server in
28 silcd/command.c that was previously used with the joining but
31 * Tested USERS command in router environment successfully with two
32 routers, two servers and two clients.
34 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
36 * Reorganized the USERS command and command reply in client library
37 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
38 When the command is given by user we register a pending command
39 callback that will reprocess the command after the reply has been
40 received from the server. When reprocessing the packet we then
41 display the information. Thus, the USERS information is displayed
42 now in the command callback instead of in the command reply
43 callback. The processing of the command is same as previously
44 when server has sent the command reply in the JOINing process.
46 * Added to USERS command in silcd/command_reply.c to join the client,
47 we didn't use to know about, to the channel after we've created
48 a client entry for it. Also, for clienet we did know already still
49 check whether it is on the channel or not and add it if not.
51 * Removed silc_server_command_join_notify as the function and its
54 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
56 * Changed the client's pending command handling to the same as the
57 server's pending command handling. It is also now possible to
58 execute command reply functions from other command reply
59 function as the function callbacks for commands and command
60 replies are one and same. The pending commands are not static
61 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
62 in client connection context. Thus, pending commands are server
63 connection specific as it is convenient.
65 Changed the function silc_client_command_pending and
66 silc_client_command_pending_del and added new function
67 silc_client_command_pending_check. Removed the
68 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
71 * Added cmd_ident, current command identifier, to the client
72 connection context in lib/silcclient/client.h to keep track on
73 command identifiers used in command sending. Client's command reply
74 function handling now supports the mandatory command identifiers.
76 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
77 funtions in client to fully support pending command callbacks.
79 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
80 as one of the arguments to the application in the command reply
83 * NOTE: The FORWARDED flag is depracated. It used to be depracated
84 before first releasing SILC but came back. Now it is removed again
85 and should come back nomore. The FORWARDED flag was used only
86 by the JOINing procedure by forwarding the command packet to router.
87 Now, the JOINing procedure has been changed to more generic (due
88 to various router environment issues) and FORWARDED is not needed
89 anymore for anything. The protocol specification is yet to be
92 Now, removed silc_server_packet_forward from server and the flag
93 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
95 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
97 * Renamed NAMES command to USERS command. The NAMES was named that
98 due to historical reasons. Now it is renamed. Also, rewrote
99 parts of the USERS command. The nickname list is not sent anymore
100 by the server. Only Client ID and mode lists are sent in the USERS
101 command. Changed this also to the protocol specification.
103 The client now resolves the names and stuff after it receives
104 the USERS list from the server when joining to the channel.
106 * WHOIS and IDENTIFY commands has been changed to support multiple
107 Client ID's per command. One can now search for multiple users
108 in the network by sending only one WHOIS or IDENTIFY command.
109 Changed the code and the protocol specifications.
111 * Removed silc_server_command_identify_parse and changed that IDENTIFY
112 uses silc_server_command_whois_parse to parse the request. */
114 * If normal server, do not parse the WHOIS and IDENTIFY requests
115 before sending it to the router. Saves some time.
117 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
119 * Fixed JOIN command on client library. Wrong number of arguments
120 used to crash the client.
122 * Added silc_server_channel_has_global function to check whether
123 channel has global users or not.
125 * Added silc_server_channel_has_local function to check whether channel
126 has locally connected clients on the channel.
128 * The silc_server_remove_from_one_channel now checks whether the
129 channel has global users or not after given client was removed from
130 the channel. It also checks whether the channel has local clients
131 on the channel anymore. If it does not have then the channel entry
132 is removed as it is not needed anymore.
134 * The silc_server_notify now checks on JOIN notify whether the joining
135 client is one of locally connected or global. If it is global then
136 the channel has now global users on the channel and that is marked
137 to the channel entry. Also, it now saves the global client to
138 global list who is joining and JOINs it to the channel. This is
139 for normal server, that is.
141 Changed silc_server_send_notify_on_channel,
142 silc_server_packet_relay_to_channel and
143 silc_server_packet_send_to_channel check if we are normal server
144 and client has router set (ie. global client) do not send the
145 message to that client, as it is already routed to our router.
147 * Implemented LEAVE notify type handling in silc_server_notify
150 * Tested LEAVE command in router environment successfully. Tested
151 with two routers, two servers and two clients.
155 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
157 * Implemented SIGNOFF notify type handling in silc_server_notify
160 * silc_server_remove_id now removes the client entry from all channels
161 it has joined and thusly sends SIGNOFF notify type.
163 * Rewrote the NAMES list generation in server by removing two excess
164 loops. The lists are created now inside one loop.
166 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * silc_server_remove_channel_user checks now also global list
169 for channel and client.
171 * silc_server_new_channel_user checks now both local and global
172 list for channel and client. Fixed a bug in client id decoding.
173 Used to decode wrong buffer.
175 * silc_server_channel_message checks now both local and global
176 list for channel entry.
178 * Tested channel joining (hence JOIN) in router environment
179 successfully. Tested with two routers, two servers and two
182 * Tested channel message sending in router environment successfully.
184 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
186 * Added silc_server_save_channel_key into server.[ch] to save the
187 received channel key in Channel Key payload processing. It is
188 also used in JOIN command reply handling.
190 Equivalent function silc_client_save_channel_key added into
191 client.[ch] into client library.
193 * Changed JOIN command reply to send information whether the channel
194 was created or not (is existing already) and the channel key
195 payload. Changed protocol specs accordingly.
197 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
198 the request was sent by ID and not by nickname. Crashed on
201 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
204 now correctly save the received data.
206 * silc_server_free_sock_user_data now notifies routers in the
207 network about entities leaving the network.
209 At the same time implemented functions silc_server_remove_id
210 and silc_server_send_remove_id to receive and send REMOVE_ID
211 packets. The packet is used to notify routers in the network
212 about leaving entities. The ID removed will become invalid in
215 * Added function silc_idlist_del_server into server. Removes and
216 free's server entry from ID list.
218 * silc_server_private_message function now checks, if we are router,
219 that the destination ID really is valid ID, naturally.
221 * In router when NEW_ID packet is received (for new client) the
222 hash of the Client ID is saved in the ID Cache but the
223 client->nickname is set to NULL, instead of putting the hash
226 IDENTIFY command now also checks that client->nickname must be
227 valid. If it is not if will request the data from the server who
228 owns the client. Added new function
229 silc_server_command_identify_check.
231 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
232 to set the command to already allocated Command Payload.
234 * Tested private message sending in router environment with two
235 routers, two servers and two clients. Fixed minor bugs and now
238 * Fixed segfault from client's NAMES command. Used to crash if
241 * Forwarded packets must not be routed even if it is not destined
242 to the receiver. Changed server code comply with this.
244 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
246 * Added `require_reverse_mapping' boolean value to ServerParams
247 structure. If TRUE (not default) the server will require that
248 the connecting host has fully qualified domain name.
250 If the reverse mapping is not required and hostname could not be
251 found the IP address is used as hostname.
253 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Implemented version string checking to both client and server.
256 The check is incomplete currently due to the abnormal version
257 strings used in development version of SILC.
259 * Changed all command functions in server to use the new
262 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Changed char *data to unsigned char *data in ID Cache system to
265 support binary data as ID Cache data. Changed code to support
266 binary data in lib/silccore/idcache.c.
268 * Renamed silc_server_packet_relay_command_reply to
269 silc_server_command_reply as it is normal packet receiving
270 function. Rewrote the function to accept command replys for
271 servers and not only for clients.
273 * Mark remote router always as registered server if we are connecting
274 to it. Otherwise, commands sent by the router to us are ignored.
276 * All ID List find routines now returns the ID Cache Entry pointer
277 as well if requested.
279 * WHOIS command works now in router environment, tested with two
280 routers, two servers and two clients.
282 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
283 in router environment (as it is almost equivalent to WHOIS) but
284 hasn't been tested thoroughly. Added new functions:
286 silc_server_command_identify_parse
287 silc_server_command_identify_send_reply
288 silc_server_command_identify_from_client
289 silc_server_command_identify_from_server
291 * Disabled route cache adding because adding two different ID's with
292 same IP replaces the old cache entry thus giving wrong route.
293 The entry->router->connection is always the fastest route anyway
294 so route cache may not be needed. Of course, new routes maybe
295 established after receiving the ID when the entry->router->connection
296 might not be anymore the most optimal.
298 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Add route cache for received ID for fast routing.
302 * Added silc_server_packet_route to route received packet on router
303 that is not destined to us.
305 * Renamed silc_server_get_route to silc_server_route_get.
307 * Added id_string and id_string_len fields into SilcServer to
308 include encoded ServerID for fast comparing without excess
309 encoding of the ID's.
311 * Cleaned up WHOIS command on server side. Added following static
314 silc_server_command_whois_parse
315 silc_server_command_whois_check
316 silc_server_command_whois_send_reply
317 silc_server_command_whois_from_client
318 silc_server_command_whois_from_server
320 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
321 arguments in command replies. All command functions should be
322 updated to use this macro.
324 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Minor typo fixes on command reply handling on server.
328 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Added silc_server_command_add_to_channel internal routine to add
331 the client to the channel after router has created the channel and
332 sent command reply to the server.
334 * Added generic silc_server_send_command to send any command from
337 * Use static buffer with ID rendering instead of duplicating data.
339 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Fixed a channel user mode bug when joining to a channel server gave
342 everybody channel founder rights, oops.
344 * We mark ourselves as the router of the incoming server connection
345 if we are router ourselves. This way we can check in some packet
346 sending functions whether it is locally connected server. For
347 incoming router connections we put NULL.
349 * For router sending packets locally means now always sending the
350 packet cell wide; to local clients and local servers. For normal
351 server sending packet locally means sending it to only local
354 * Fixed the JOIN command to really work in router environment. If the
355 channel is created it is always created by the router. Router is
356 also responsible of making the initial joining to the channel,
357 sending JOIN notify to the sending server and distributing
358 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
359 does not exist server doesn't do anything else but forward the
360 command to the router which performs everything.
362 * Added silc_server_send_channel_key function to send the Channel Key
365 * Added silc_server_create_channel_key to create new channel key. The
366 channel key is now re-generated everytime someone joins or leaves
367 a channel, as protocol dictates. Note: channel->key_len is the
370 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Splitted server.[ch] finally. Created now packet_send.[ch] and
373 packet_receive.[ch] to separate packet sending and receiving
374 routines. The server.[ch] now includes everything else including
375 actual packet processing (writing and reading data) and other
378 Renamed silc_server_private_message_send_internal to
379 silc_server_send_private_message. The routine is still though
380 used only to relay private messages as server does not send
381 private messages itself.
383 Renamed silc_server_new_channel to silc_server_create_new_channel
384 and added new function sicl_server_new_channel that handles the
385 incoming New Channel packet. Added also new sending function
386 silc_server_send_new_channel to send New Channel Payload.
388 * Added new function silc_server_notify to process incoming notify
389 packet to the server/router. Server may then relay the notify
390 to clients if needed.
392 * Added new function silc_server_new_channel_user to process incoming
393 New Channel User packet. Router will redistribute the packet and
394 send JOIN notify to its local clients and locally connected servers
395 if needed. Normal server will send JOIN notify to its local client
396 on same channel when received this packet. Added also corresponding
397 sending function silc_server_send_new_channel_user to sent the
400 * Added boolean route argument to send_notif_to_channel and
401 packet_send_to_channel functions to attempt to route the packet
402 if it is TRUE and send only locally if it is FALSE.
404 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * silc_server_replace_id now broadcasts the received replace ID
407 packet if it is not broadcast packet already. The router must
408 broadcast to inform other routers about changed ID.
410 * Added backpointer to server's router into SilcServer context in
411 silcd/server_internal.h.
413 * Fixed silc_server_packet_broadcast to send correct broadcast
416 * The channel key is now distributed to the local client as soon
417 as it is received from the router (in router environment) so that
418 no other packet may be sent for the channel until client has
421 * silc_server_remove_channel_user now broadcasts the received
422 Remove Channel User packet if it is not broadcast packet already.
423 The router must broadcast to inform other routers about removed
426 * Added users field into SilcPacketContext that is a reference count
427 of the context. One can increase the reference count by calling
428 silc_packet_context_dup which is now changed to just increase the
429 reference count instead of duplicating the data. The reference
430 count is decresed by calling silc_packet_context_free that will
431 free the data after the reference count hits zero.
433 For now on the packet context and everything allocated into it
434 (including the raw packet from network) must be freed by calling
435 the new silc_packet_context_free function. Added also new function
436 silc_packet_context_alloc that must be used now to allocate the
437 context. This also means that if a routine is asynchronous from
438 silc_[client/server]_packet_parse_type the packet context must
439 be duplicated by calling silc_packet_context_dup. Otherwise it
440 gets free'd after silc_[client/server]_packet_parse_type returns.
441 Also, one must remember that if packet is duplicated then its
442 reference count must be decresed by calling the free function as
443 many times as it was duplicated.
445 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
446 from both client and server.
448 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Made joining to a channel working in router environment.
452 * Cleaned up JOIN command on server side and create function
453 silc_server_command_join_channel internal routine to make the
456 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * Changed silc_command_pending list to SilcDList. Also, added
459 `ident' field to SilcServerCommandPending structure to identify
460 the reply and to call correct callback.
462 Added silc_server_command_pending_check function to replace the
463 corresnponding macro. The silc_command_pending list is not
466 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
467 to set identifier to previously allocated Command Payload. It
468 is used to set identifier for command when resending Command
471 * Added silc_command_payload_encode_payload to encode Command
472 Payload buffer from SilcCommandPayload structure.
474 * Added silc_argument_payload_encode_payload to encode Argument
475 payload buffer from SilcArgumentPayload structure.
477 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Changed WHOIS command to support router connection on server side.
480 The whois request is always sent to router unless the server is
481 standalone server. After server has received the reply from the
482 router will it send the reply to the client.
484 * Added silc_server_packet_broadcast into silcd/server.[ch] to
485 broadcast received broadcast packet. The function is used only
486 by router. The broadcast packet is always sent to the router's
489 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
490 render given ID to printable string, for log files for example.
492 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
494 * Made basic router to router connections working. At least they
495 can now connect to each other but nothing really works the way
496 they are supposed - yet.
498 * Added new initiator token to RouterConnection configuration
499 file in silcd/serverconfig.[ch]. It is used to tell whether we
500 are the initiator to the remote router or whether we'll expect
501 the other end to connect.
503 * Moved registering of listener task to silc_server_init, hence
504 the server starts listenning as soon as it is run, even if it
505 does not have connections to other routers. Let's see how well
508 * Changed default connection retry timeouts for more suitable in
511 * Removed cipher and such arguments from silc_idlist_add_client
512 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
513 Added new function silc_idlist_add_data to add the keys and stuff
516 * Added SilcIDListData structure and added it to SilcClientEntry
517 and SilcServerEntry as their first field in the structure. This
518 way we can explicitly cast the ID entries to the SilcIDListData
519 structure and get common data for the entries. In past, we had
520 to first check what type of connection it is and then cast it to
521 correct ID entry type. Now, we can directly cast the opaque
522 pointer to the SilcIDListData (no matter what ID entry it actually
523 is) and get the data needed.
525 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
527 * Wow, found a bug in scheduler. The scheduler uninitialized itself
528 in some circumstances even if threre were timeout tasks, though not
529 IO tasks, but tasks anyway. Now fixed.
531 * Defined SilcServerConnection structure to hold connection specific
532 stuff about directly connected servers and routers. The definition
533 is currently in silcd/server_internal.h. I thought about having
534 a bit more important role fro this struct but for now it is used
535 only when connecting to other server (or router actually).
537 * Added connecting retry support in server when connecting to
538 router(s). The retry feature implement exponential backoff
539 algorithm. Also, added SilcServerParams structure to hold default
540 parameters for server. For now, it include these retry settings
541 and are hard coded. After server is moded to be as Silc Server
542 Library this structure will be more important.
544 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Changed client librarys channel->clients table to SilcList and
547 changed code accordingly.
549 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Changed client's channel table to SilcList and changed code
552 accordingly. Also changed SilcChannelClientEntry to include back-
553 pointer to the channel so that client entry can use that structure
554 as list as well and we have fast cross-reference to the channel.
555 This change dramatically decreased the complexity of channel
556 handling with client entry and vice versa (removed one extra
557 loop when searching for channel entry from many functions).
559 * Changed server->sim from table to SilcDList and changed code
562 * NAMES command can now be used from user interface. It will show
563 the user list on the channel, neatly.
565 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
566 Code now saves realname of the user if it becomes available.
568 * Renamed configure.in to configure.in.pre and made ./prepare
569 script to automatically add correct version string to
570 configure.in which it creates from configure.in.pre.
572 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * NAMES command reply now shows users mode with the nickname when
577 * Moved silc_client_ch[u]mode[_char] functions from
578 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
579 place sucks, they are utility functions and should be in some
582 * Fixed some unsigned int's to unsigned short's. Patch by cras.
584 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
587 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Added TRQ (efficient deque and list library) into lib/trq. This is
592 a very good list library that is currently used in the SILC. Defined
593 SilcList API over the library because I didn't like the API very
594 much. See lib/trq/silclist.h for the API and examples of how to
595 use the API. Fixed various places in the code to use the new
596 SilcList API. The SilcList is meant for lists that has a structure
597 already defined as a list. It is not suitable to add just some
598 context to the list (in TRQ, the context is the list actually).
600 So, I defined SilcDList that can be used for the purpose where
601 predefined list structure does not exit. This can be used as
602 such list. Now some context just can be added to the SilcDList.
603 Currently this list is not used in the SILC just yet, though there
604 are a lot places where this can replace dynamically allocated
605 tables and I will fix these places, later, to use SilcDList.
606 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
607 and use TRQ internally).
609 Also fixed some annoying warning messages that the original TRQ
610 code generated. Also minor changes to TRQ's Makefile.in.
612 * Added support for querying by Client ID to both WHOIS and
613 IDENTIFY commands into server, as required by the protocol.
615 * Removed method function pointers from SilcBuffer structure. They
616 weren't used to anything and just increased the context size for
617 no good reason. This change also made silc_buffer_alloc and
618 silc_buffer_free functions inline functions.
620 * Disabled command flooding detection support until it's fixed so
621 that it accepts commands in but does not execute them more than once
624 * Added silc_net_localhost(), to return local hostname, into
625 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
626 that must be initialized before calling silc_client_init.
628 * Added new function: silc_server_send_notify_on_channels to send
629 notify messages to all channels client has joined. It is assured
630 that the message is sent only once per client.
632 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
633 lib/silcutil/silcutil.[ch] as silc_format function. The new
634 function is generic and is used by server as well, not only by
635 the logging routines.
637 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
638 the provided version string was not acceptable. Added new function:
639 silc_ske_check_version into lib/silcske/silcske.h. The function
640 must be implemented by the application (client or server) and it
641 does not reside in the SKE library. The function checks the version
642 string remote end sent.
644 * Added back pointers (to opaque context and to SilcSocketConnection)
645 into SilcPacketContext structure into lib/silccore/silcpacket.h.
647 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
648 duplicate packet context structure.
650 * Changed `notify' client operation to send same arguments as client
651 receives from server except for ID's. ID's are mapped to correct
652 ID entry and that is returned. Also, if channel entry is not sent
653 by server but the notify is for channel the channel entry is sent
654 to application (otherwise application doesn't know that it is for
655 channel (library gets it from packet's Destination ID)).
657 * Added silc_client_remove_from_channels into client library to
658 remove a client from all channels it has joined to. Used when
659 received SIGNOFF notify from server. Added also new function
660 silc_client_replace_from_channels to replace old ID entry with
661 new ID entry on all channels. Used when received NICK_CHANGE
664 * Fixed ID Cache list handling in silc_idlist_get_client in
665 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
666 to get (or query) client by ID.
670 * Added connection authentication status message defined by the
671 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
672 support for these into the code in client and server side.
674 * Added generic function silc_client_send_command to send any command
675 with variable argument list. Application should use this function
676 to send commands if the command functions provided by the library
677 does not suite for the application's user interface needs.
679 * Added new `failure' client operation. Application is notified about
680 received failure packet if client is executing a protocol. In this
681 case the protocol's execution has failed.
683 * Added SKE's end notify to send the SKE_SUCCESS notify message that
684 is required by the protocol.
686 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
687 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
690 * Added status flag to SilcSKE object to indicate realtime status
693 * Application receives now exactly same command reply arguments as
694 the library receives from server. However, if ID is received the
695 corresponding ID entry is returned to the application (eg. Client
696 ID is mapped to correct SilcClientEntry entry and that is returned).
697 Changed command_reply client operation due to this change.
699 * Changed all ID's in commands and in command replys as ID Payloads.
700 Change affected both client and server side codes.
702 All ID's sent in SILC network (with execption of ID's in SILC
703 Packet header) are sent in ID Payload to support variable length
706 * Server now notifies nick changes and notifies all clients on
707 the channels about the new nickname (about the new Client ID,
710 * Implemented CMODE command to change channel modes. Supports all
711 channel modes defined by the protocol specs except ban and invite
712 lists. (Also, private channel key mode is supported but support for
713 setting private channel key in client is missing, thus, this mode
714 has no effect on client side (except that server requires that the
715 client uses private channel key and normal channel traffic does not
718 Also, invite mode works per se, but INVITE command does not work
719 yet correctly, so you can set channel as invite only channel but
720 inviting clients to the channel does not work (it is yet to be
721 thought what's the best way to do it).
723 * Added new command SILC_COMMAND_CUMODE to change user mode on the
724 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
725 Implemented CUMODE command to change user's mode on the channel.
726 Supports all modes defined by the protocol specs.
728 * Added NAMES command reply to return users modes on the channel.
730 * Removed unnecessary and slow ciphers from lib/silccrypt.
732 * Set SO_KEEPALIVE option to connection sockets by default.
734 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
736 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
737 redefined the Notify Payload into protocol specs.
739 * Added silc_id_payload_parse_id to get ID directly from raw
742 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
745 accept searching by Client ID as well.
747 * Added support for LEAVE and SIGNOFF notify types in client library.
749 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
750 to parse ID Payload from raw data.
752 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Added flags parameter into silc_ske_assemble_security_properties
755 function in lib/silcske/silcske.[ch].
757 * Changed notify client operation to fit better for notify messages
758 sent by server. The notify payload received from server is now
759 passed to the application (after parsing it to SilcNotifyPayload).
760 It is application's responsibility to retrieve the arguments
761 from the payload and show the message the way it wants. The message
762 sent by server is implementation specific.
764 * Changed public keys to comply with the protocol specification.
765 Old public keys are not supported anymore and are not compatible.
767 * Removed nickname from Channel Payload as the latest draft removed
768 it. The client must resolve the nickname from the NAMES command
769 reply received when it joined the channel.
771 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
773 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
775 * Fixed some errors in protocol specification drafts.
777 * Created lib/silccore/silcnotify.c to implement Notify Payload
778 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
779 generic payloads described by protocol specifications. The file
780 includes implementations for ID Payload and Argument Payload.
782 * Changed Command Payload implementation to use the new Argument
783 Payload. Changed command_xxxx_payload to command_payload_xxxx
784 to comply with SILC coding conventions.
786 * Added suppport for Argument Payload handling in Notify Payload
787 implementation as protocol requires it. Added the new support
788 into server and client lib as well.
790 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
792 * Added support for multiple nicknames on same channel. [n] is
793 added locally to the nickname if there are more than one same
794 nicknames on the channel.
796 * Server now sends all nicknames that matched WHOIS request.
797 Client also shows the list received from server.
799 * Added TOPIC command to client side. User can now set and show
800 current topic on channel.
802 * Added MOTD command to client and server. Also, server sends the
803 motd when client connects to the server.
805 * Changed version strings to comply ISO 8601.
807 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Fixed protocol error handling in client library. It should now
810 cope even if the SKE fails for some reason.
812 * Made new protocol specification drafts for submitting to IETF.
814 * Implemented TOPIC command to server in silcd/command.c.
816 * Added two new notify types into lib/silccore/silcnotify.h:
817 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
818 notify nickname change and topic setting/change on a channel.
820 * API change of command_reply operation in client library. The
821 application gets now the status type received from server as well.
823 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Removed the function just added to lib/silcutil/silcschedule.[ch].
827 * Cras fixed and optimized the packet handling even further and
828 it should work now. Minor change to the prototype of function
829 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
831 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
833 * Added new function into lib/silcutil/silcschedule.[ch]:
834 silc_schedule_with_fd to select() a specified fd. The function
835 returns after timeout expires or data arrives or goes. The
836 function is used by packet routines to wait that all data is
837 received from network.
839 * Fixed data reading from network in lib/silccore/silcpacket.c.
840 The code now assures that all data is read from the fd and then
841 continues packet processing. This was a bug fix since the code
842 used to drop some data in some circumstances.
844 * Added new function into lib/silcclient/client.[ch]:
845 silc_client_start_key_exchange to start key exchange after
846 connection has been established to server. The code internally
847 now uses this funtion but its main purpose was to provide it
848 for applications that perform their own connecting. After
849 application has created a connection it merely calls this
850 function to start the key exchange between client and server.
851 The library takes care of everything else after that.
853 Updated also lib/silcclient/README to explain the usage of
856 * Do not send to application information that connection has
857 been established. Application gets notified it by connect
860 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Applied cras's patch to add silc_schedule_one function. The
863 function runs scheduler once and returns.
865 * Fixed the scheduler after cras messed it up. The timeout
866 handling works now as it's supposed to work.
868 * Added into lib/silccore/ silcnotify.h to include notify
869 message types support. Changed silc_server_send_notify*
870 functions, in server.[ch], to support those new notify types.
871 Added the support for the notify types into client library,
872 as well. Added new notify client operation into ops.h in
875 * Changed silc_server_packet_send_to_channel to send normal
876 packets instead of just channel message packets. The function
877 is now used to send the notify packets to channels. It is not
878 used to send channel message packets anymore, as server never
881 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
882 va_arg()s as it seems to require it nowadays. I guess, if SILC
883 is compiled with older va_arg() the new code should work anyway.
885 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Splitted core library. Core library (lib/silccore) includes
888 now only SILC protocol specific core (and common) components.
889 Created new utility library (lib/silcutil) that includes more
890 generic purpose stuff. The stuff for util library was taken
891 from the old core library. This was minor and easy split.
893 * Created SILC Client Library (lib/silcclient) that includes
894 implementation of the SILC client without user interface. This
895 was major move from silc/ directory. The code has been changed
896 so that it is transparent towards the user interface. The
897 silc/ directory includes now the same user interface as before
898 and it uses the new client library. Read lib/silcclient/README.
899 Basicly, the client library performs everything else related
900 to SILC except user interface handling. Also, configuration
901 files are considered to be part of user interface and library
902 does not handle them.
904 This change also changed a lot of structures, function naming etc.
905 Most important change was that SilcClientWindow object was
906 renamed to SilcClientConnection in the client library. Created
907 also new file lib/silcclient/ops.h. Also added new files
908 silc/local_command.[ch] and silc/client_ops.[ch].
910 All these changes were made to make it easier for user interface
911 designers to create what ever user interface for the SILC client
914 It is also expected that the server will be moved to lib
915 directory as well and SILC Server Library will be created;
916 sometimes in the future.
918 * Removed Local commands from lib/silccore/silccommand.h as
919 they are application specific and new client library does not
920 handle any of those anymore.
922 * Several functions moved to lib/silcutil/silcutilc.[ch] from
923 old client implementation in silc/.
925 * Added support for callback functions in SILC_LOG_* macros.
926 Application can now set its own callbacks that will be called
927 instead of using the default functions that will always print
928 the debug messages to stderr (or stdout). Also, debugging can
929 now be disabled by setting silc_debug to FALSE and re-enabled by
930 setting it to TRUE. Note, that logging will still work even
931 if debugging is disabled.
933 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
934 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
935 silc_log_reset_debug_callbacks.
937 * To enable debugging in silc client one must give now -d
938 option on command line.
940 * Changed silc_schedule_init to automatically allocate task queues
941 if they are not allocated before calling it.
943 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Added GMP 3.1 into math library.
947 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
950 a channel in SILC network. The packet is used by servers and
951 routers to notify other routers that user has left a channel.
952 This little feature was missing until now. Added the feature
953 to protocol specification as well.
955 Added functions: silc_server_send_remove_channel_user and
956 silc_server_remove_channel_user into server.[ch].
958 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
959 lib/silccore/silcpacket.h. However, they are not implemented
962 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Fixed joining to a channel and sending channel messages
965 between server and router. The channel message sending should
966 now work inside a cell.
968 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
970 * Fixed the private message sending between server and router.
971 The private message sending should now work inside a cell.
973 * Added silc_server_replace_id into server.[ch] to replace
974 existing ID in the SILC network.
976 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
977 and silc_idlist_replace_server_id into idlist.[ch] in server.
979 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Fixed the server to server connections. Server can again now
982 connect to router. Router to router connections probably does
985 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added dynamic protocol registering support. Now protocols can
988 registered and unregistered on the fly. Patch by cras.
990 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Added lib/contrib directory to hold routines that some platforms
993 don't have but are needed by SILC.
995 * Added getopt.c, getopt1.c and getopt.h from GNU C library
996 into lin/contrib to provide getopt() and getopt_long() for
997 those who don't have it.
999 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Added AWAY command to client. When away message is set and
1002 client receives a private message packet the client automatically
1003 replies to the sender with the away message.
1005 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1006 bug seemed to be the cause of recent problems when compiling
1009 * Added version detection support to SKE protocol specification
1010 and added the new changes to the SKE implementation as well.
1011 There were other minor changes in the SKE protocol as well.
1013 Many changes in lib/silcske/silcske.[ch] and in
1014 lib/silcske/payload.[ch].
1016 * Added ^U functionality, clear input line. Patch from cras.
1018 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Mainly small bugfixes on core library. Fixed some debugging
1021 logging and buffer overflow in silclog.c.
1023 * Updated config.sub and config.guess on the distribution tree.
1025 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Added command lagging support in server. Client may execute
1028 commands now only once in two seconds.
1030 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Optimized packet reception. MAC computation and checking is now
1033 also more optimized. A lot previously duplicated code is now
1034 used as generic by both client and server.
1036 * Fixed key pair generation in clientutil.c
1038 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * Added into lib/silccore/silcbufutil.[ch] new function;
1041 silc_buffer_realloc.
1043 * Moved generic packet sending/encryption functions to
1044 lib/silccore/silcpacket.[ch] from client and server. Some
1045 rewriting of the functions.
1047 * Moved all generic packet reception/decryption functions to
1048 lib/silccore/silcpacket.[ch] from client and server. The
1049 packet processing is now much cleaner in both client and server.
1050 These were major changes in both client and server.
1052 * Created many common functions in server to do packet sending.
1053 Previously code were duplicated a lot, this has been removed
1056 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Rewrote major parts of the ID cache system. Don't know
1059 whether it is better now or not but at least the API is more
1062 * Major rewrite on ID cache stuff on client because of the ID
1063 cache API changes. Added idlist.c to client.
1065 * Also major rewrite on ID cache stuff on server as well.
1066 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1067 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1068 in hand, instead they are all put into the ID cache system now.
1069 All server_idlist_* routines uses ID cache now instead of
1070 traversing its own lists (those lists does not exist anymore).
1071 SilcIDList though still exists. Also, SilcXXXEntry's are
1074 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Finally made the SKE implementation compliant to the protocol
1077 specification. All mp integers are now binary encoded as
1078 opposed being HEX encoded.
1080 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1083 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1084 functions: silc_[encode/decode]_pem. Also added function
1085 silc_encode_pem_file to PEM encode with newlines ('\n') for
1088 * SILC public keys are now encoded either PEM or binary. Same
1089 option is for private keys as well. By default private keys
1090 are binary encoded and public keys PEM encoded. Silly HEX
1091 encoding were removed.
1093 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1094 function to create fingerprints.
1096 * Fixed a bug in SHA1; does not change the original data anymore.
1098 * Partly implemented INFO command on client and server side.
1099 Fixed CLEAR command. Changes to SERVER command; show current
1100 server(s) when giving command without arguments. Added
1101 VERSION command to client.
1103 * Added check to server that unregistered connections cannot
1104 execute commands (unless it is specificly allowed).
1106 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Fixed screen refresh.
1110 * Fixed channel joining bug from client. On some circumstances
1111 client tried to join to a channel it had already joined.
1113 * Added public key verification process into client's protocol.c.
1114 The client now verifies the public key from user and saves
1115 it into ~./silc/serverkeys/ directory.
1117 Added into: clientutil.[ch]: silc_client_verify_server_key.
1119 * Changed SKE protocol's silc_ske_initiator_finish function
1120 to accept callback function that verifies the received public
1121 key. Removed old silc_ske_verify_public_key function.
1123 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1125 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1126 silc_pkcs_private_key[_data]_set.
1128 * Made the password and public authentication more cleaner in
1129 server's protocol.c.
1131 * Removed historic and obsolete protocol `channel_auth' from
1132 both client and server.
1134 * Removed wrong way of sending command status messages from
1135 server to client in server's command.c. The old way violated
1136 protocol specification.
1138 Changes to silccore/silccommand.[ch]: removed
1139 silc_command_encode_status_payload -> not needed anymore,
1140 changed silc_command_encode_payload_va to accept extra
1141 argument on variable argument list. The argument type must
1142 now be provided to the function. Also, added new function:
1143 silc_command_encode_reply_payload_va which is same as
1144 normal command_encode_payload_va except command status type
1145 is provided as extra argument.
1147 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Added ~./silc directory handling. The directory includes the
1150 public and private keys for the client.
1152 Added silc_client_check_silc_dir, silc_client_create_identifier
1153 and silc_client_load_keys.
1155 * Implemented SILC protocol compliant public key. Added public
1156 and private key saving to and loading from files.
1158 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1159 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
