1 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new packet type SILC_PACKET_SET_MODE that is used to
4 distribute the information about changed modes (for clients,
5 channels and clients channel modes) to all routers in the
6 network. Updated the protocol specification accordingly.
8 Added functions into silcd/packet_send.c and
9 silcd/packet_receive.c: silc_server_send_set_mode,
12 Added new files silcmode.[ch] into lib/silccore that implements
13 the encoding and decoding of Set Mode Payload. Added new type
14 SilcSetModePayload. Moved the definitions of different modes
15 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
17 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Oops, a little mistake in server's connection authentication
20 protocol. The protocol is not ended with FAILURE but with
21 SUCCESS if the authentication is Ok. :) Affected file is
24 * Implemented NICK_CHANGE notify handling in server in the file
25 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
26 the local clients on the channel. After the changing nickname
27 in router environment snhould work and the [<unknown>] nickname
28 should appear no more.
30 The silc_server_replace_id function that receives the Replace ID
31 payload now sends the NICK_CHANGE notify type also in the file
32 silcd/packet_receive.c
34 * Changed WHOIS and IDENTIFY command to support the maximum amount
35 of arguments defined in protocol specs (3328 arguments). This
36 fixed a bug that caused problems when there were more than three
39 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
41 * Added extra parameter, command identifier, to the
42 silc_client_send_command so that explicit command identifier
45 Changed that ID list routines uses specific command identifier
46 when sending WHOIS/IDENTIFY requests to the server so that they
47 can be identified when the reply comes back.
49 Affected files lib/silcclient/command.[ch],
50 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
52 * Added `sender' argument to silc_server_packet_send_to_channel
53 to indicaet the sender who originally sent the packet to us
54 that we are now re-sending. Ignored if NULL. Affected file
55 silcd/packet_send.[ch].
57 * Added some server statistics support in silcd/server_internal.h
58 SilcServerStatistics structure and around the server code. Also
59 send some nice statistics information when client is connecting
62 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Fixed channel ID decoding in server's JOIN command reply in
67 * Fixed braodcasting of replace ID payload to not to send it if
68 we are standalone server in silcd/packet_receive.c.
70 * Fixed all channel message sending routines to not to send
71 packets to clients that has router set, since they are routed
72 separately in the same function earlier. Affects file
73 silcd/packet_send.c and all channel packet sending functions.
75 * In USERS reply, res_argv[i] are not allocated, the table
76 is allocated. Thus changed that free the table, not its
79 * In server's whois_check and identify_check if the client is
80 locally connected do not send any WHOIS commands - they are not
83 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Fixed some minor bugs in client when sending WHOIS command. The
86 arguments was in wrong order.
88 * Removed statis function add_to_channel from server in
89 silcd/command.c that was previously used with the joining but
92 * Tested USERS command in router environment successfully with two
93 routers, two servers and two clients.
95 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
97 * Reorganized the USERS command and command reply in client library
98 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
99 When the command is given by user we register a pending command
100 callback that will reprocess the command after the reply has been
101 received from the server. When reprocessing the packet we then
102 display the information. Thus, the USERS information is displayed
103 now in the command callback instead of in the command reply
104 callback. The processing of the command is same as previously
105 when server has sent the command reply in the JOINing process.
107 * Added to USERS command in silcd/command_reply.c to join the client,
108 we didn't use to know about, to the channel after we've created
109 a client entry for it. Also, for clienet we did know already still
110 check whether it is on the channel or not and add it if not.
112 * Removed silc_server_command_join_notify as the function and its
115 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
117 * Changed the client's pending command handling to the same as the
118 server's pending command handling. It is also now possible to
119 execute command reply functions from other command reply
120 function as the function callbacks for commands and command
121 replies are one and same. The pending commands are not static
122 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
123 in client connection context. Thus, pending commands are server
124 connection specific as it is convenient.
126 Changed the function silc_client_command_pending and
127 silc_client_command_pending_del and added new function
128 silc_client_command_pending_check. Removed the
129 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
132 * Added cmd_ident, current command identifier, to the client
133 connection context in lib/silcclient/client.h to keep track on
134 command identifiers used in command sending. Client's command reply
135 function handling now supports the mandatory command identifiers.
137 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
138 funtions in client to fully support pending command callbacks.
140 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
141 as one of the arguments to the application in the command reply
144 * NOTE: The FORWARDED flag is depracated. It used to be depracated
145 before first releasing SILC but came back. Now it is removed again
146 and should come back nomore. The FORWARDED flag was used only
147 by the JOINing procedure by forwarding the command packet to router.
148 Now, the JOINing procedure has been changed to more generic (due
149 to various router environment issues) and FORWARDED is not needed
150 anymore for anything. The protocol specification is yet to be
153 Now, removed silc_server_packet_forward from server and the flag
154 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
156 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Renamed NAMES command to USERS command. The NAMES was named that
159 due to historical reasons. Now it is renamed. Also, rewrote
160 parts of the USERS command. The nickname list is not sent anymore
161 by the server. Only Client ID and mode lists are sent in the USERS
162 command. Changed this also to the protocol specification.
164 The client now resolves the names and stuff after it receives
165 the USERS list from the server when joining to the channel.
167 * WHOIS and IDENTIFY commands has been changed to support multiple
168 Client ID's per command. One can now search for multiple users
169 in the network by sending only one WHOIS or IDENTIFY command.
170 Changed the code and the protocol specifications.
172 * Removed silc_server_command_identify_parse and changed that IDENTIFY
173 uses silc_server_command_whois_parse to parse the request. */
175 * If normal server, do not parse the WHOIS and IDENTIFY requests
176 before sending it to the router. Saves some time.
178 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
180 * Fixed JOIN command on client library. Wrong number of arguments
181 used to crash the client.
183 * Added silc_server_channel_has_global function to check whether
184 channel has global users or not.
186 * Added silc_server_channel_has_local function to check whether channel
187 has locally connected clients on the channel.
189 * The silc_server_remove_from_one_channel now checks whether the
190 channel has global users or not after given client was removed from
191 the channel. It also checks whether the channel has local clients
192 on the channel anymore. If it does not have then the channel entry
193 is removed as it is not needed anymore.
195 * The silc_server_notify now checks on JOIN notify whether the joining
196 client is one of locally connected or global. If it is global then
197 the channel has now global users on the channel and that is marked
198 to the channel entry. Also, it now saves the global client to
199 global list who is joining and JOINs it to the channel. This is
200 for normal server, that is.
202 Changed silc_server_send_notify_on_channel,
203 silc_server_packet_relay_to_channel and
204 silc_server_packet_send_to_channel check if we are normal server
205 and client has router set (ie. global client) do not send the
206 message to that client, as it is already routed to our router.
208 * Implemented LEAVE notify type handling in silc_server_notify
211 * Tested LEAVE command in router environment successfully. Tested
212 with two routers, two servers and two clients.
216 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
218 * Implemented SIGNOFF notify type handling in silc_server_notify
221 * silc_server_remove_id now removes the client entry from all channels
222 it has joined and thusly sends SIGNOFF notify type.
224 * Rewrote the NAMES list generation in server by removing two excess
225 loops. The lists are created now inside one loop.
227 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * silc_server_remove_channel_user checks now also global list
230 for channel and client.
232 * silc_server_new_channel_user checks now both local and global
233 list for channel and client. Fixed a bug in client id decoding.
234 Used to decode wrong buffer.
236 * silc_server_channel_message checks now both local and global
237 list for channel entry.
239 * Tested channel joining (hence JOIN) in router environment
240 successfully. Tested with two routers, two servers and two
243 * Tested channel message sending in router environment successfully.
245 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Added silc_server_save_channel_key into server.[ch] to save the
248 received channel key in Channel Key payload processing. It is
249 also used in JOIN command reply handling.
251 Equivalent function silc_client_save_channel_key added into
252 client.[ch] into client library.
254 * Changed JOIN command reply to send information whether the channel
255 was created or not (is existing already) and the channel key
256 payload. Changed protocol specs accordingly.
258 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
259 the request was sent by ID and not by nickname. Crashed on
262 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
265 now correctly save the received data.
267 * silc_server_free_sock_user_data now notifies routers in the
268 network about entities leaving the network.
270 At the same time implemented functions silc_server_remove_id
271 and silc_server_send_remove_id to receive and send REMOVE_ID
272 packets. The packet is used to notify routers in the network
273 about leaving entities. The ID removed will become invalid in
276 * Added function silc_idlist_del_server into server. Removes and
277 free's server entry from ID list.
279 * silc_server_private_message function now checks, if we are router,
280 that the destination ID really is valid ID, naturally.
282 * In router when NEW_ID packet is received (for new client) the
283 hash of the Client ID is saved in the ID Cache but the
284 client->nickname is set to NULL, instead of putting the hash
287 IDENTIFY command now also checks that client->nickname must be
288 valid. If it is not if will request the data from the server who
289 owns the client. Added new function
290 silc_server_command_identify_check.
292 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
293 to set the command to already allocated Command Payload.
295 * Tested private message sending in router environment with two
296 routers, two servers and two clients. Fixed minor bugs and now
299 * Fixed segfault from client's NAMES command. Used to crash if
302 * Forwarded packets must not be routed even if it is not destined
303 to the receiver. Changed server code comply with this.
305 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
307 * Added `require_reverse_mapping' boolean value to ServerParams
308 structure. If TRUE (not default) the server will require that
309 the connecting host has fully qualified domain name.
311 If the reverse mapping is not required and hostname could not be
312 found the IP address is used as hostname.
314 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
316 * Implemented version string checking to both client and server.
317 The check is incomplete currently due to the abnormal version
318 strings used in development version of SILC.
320 * Changed all command functions in server to use the new
323 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
325 * Changed char *data to unsigned char *data in ID Cache system to
326 support binary data as ID Cache data. Changed code to support
327 binary data in lib/silccore/idcache.c.
329 * Renamed silc_server_packet_relay_command_reply to
330 silc_server_command_reply as it is normal packet receiving
331 function. Rewrote the function to accept command replys for
332 servers and not only for clients.
334 * Mark remote router always as registered server if we are connecting
335 to it. Otherwise, commands sent by the router to us are ignored.
337 * All ID List find routines now returns the ID Cache Entry pointer
338 as well if requested.
340 * WHOIS command works now in router environment, tested with two
341 routers, two servers and two clients.
343 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
344 in router environment (as it is almost equivalent to WHOIS) but
345 hasn't been tested thoroughly. Added new functions:
347 silc_server_command_identify_parse
348 silc_server_command_identify_send_reply
349 silc_server_command_identify_from_client
350 silc_server_command_identify_from_server
352 * Disabled route cache adding because adding two different ID's with
353 same IP replaces the old cache entry thus giving wrong route.
354 The entry->router->connection is always the fastest route anyway
355 so route cache may not be needed. Of course, new routes maybe
356 established after receiving the ID when the entry->router->connection
357 might not be anymore the most optimal.
359 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Add route cache for received ID for fast routing.
363 * Added silc_server_packet_route to route received packet on router
364 that is not destined to us.
366 * Renamed silc_server_get_route to silc_server_route_get.
368 * Added id_string and id_string_len fields into SilcServer to
369 include encoded ServerID for fast comparing without excess
370 encoding of the ID's.
372 * Cleaned up WHOIS command on server side. Added following static
375 silc_server_command_whois_parse
376 silc_server_command_whois_check
377 silc_server_command_whois_send_reply
378 silc_server_command_whois_from_client
379 silc_server_command_whois_from_server
381 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
382 arguments in command replies. All command functions should be
383 updated to use this macro.
385 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
387 * Minor typo fixes on command reply handling on server.
389 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Added silc_server_command_add_to_channel internal routine to add
392 the client to the channel after router has created the channel and
393 sent command reply to the server.
395 * Added generic silc_server_send_command to send any command from
398 * Use static buffer with ID rendering instead of duplicating data.
400 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Fixed a channel user mode bug when joining to a channel server gave
403 everybody channel founder rights, oops.
405 * We mark ourselves as the router of the incoming server connection
406 if we are router ourselves. This way we can check in some packet
407 sending functions whether it is locally connected server. For
408 incoming router connections we put NULL.
410 * For router sending packets locally means now always sending the
411 packet cell wide; to local clients and local servers. For normal
412 server sending packet locally means sending it to only local
415 * Fixed the JOIN command to really work in router environment. If the
416 channel is created it is always created by the router. Router is
417 also responsible of making the initial joining to the channel,
418 sending JOIN notify to the sending server and distributing
419 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
420 does not exist server doesn't do anything else but forward the
421 command to the router which performs everything.
423 * Added silc_server_send_channel_key function to send the Channel Key
426 * Added silc_server_create_channel_key to create new channel key. The
427 channel key is now re-generated everytime someone joins or leaves
428 a channel, as protocol dictates. Note: channel->key_len is the
431 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Splitted server.[ch] finally. Created now packet_send.[ch] and
434 packet_receive.[ch] to separate packet sending and receiving
435 routines. The server.[ch] now includes everything else including
436 actual packet processing (writing and reading data) and other
439 Renamed silc_server_private_message_send_internal to
440 silc_server_send_private_message. The routine is still though
441 used only to relay private messages as server does not send
442 private messages itself.
444 Renamed silc_server_new_channel to silc_server_create_new_channel
445 and added new function sicl_server_new_channel that handles the
446 incoming New Channel packet. Added also new sending function
447 silc_server_send_new_channel to send New Channel Payload.
449 * Added new function silc_server_notify to process incoming notify
450 packet to the server/router. Server may then relay the notify
451 to clients if needed.
453 * Added new function silc_server_new_channel_user to process incoming
454 New Channel User packet. Router will redistribute the packet and
455 send JOIN notify to its local clients and locally connected servers
456 if needed. Normal server will send JOIN notify to its local client
457 on same channel when received this packet. Added also corresponding
458 sending function silc_server_send_new_channel_user to sent the
461 * Added boolean route argument to send_notif_to_channel and
462 packet_send_to_channel functions to attempt to route the packet
463 if it is TRUE and send only locally if it is FALSE.
465 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * silc_server_replace_id now broadcasts the received replace ID
468 packet if it is not broadcast packet already. The router must
469 broadcast to inform other routers about changed ID.
471 * Added backpointer to server's router into SilcServer context in
472 silcd/server_internal.h.
474 * Fixed silc_server_packet_broadcast to send correct broadcast
477 * The channel key is now distributed to the local client as soon
478 as it is received from the router (in router environment) so that
479 no other packet may be sent for the channel until client has
482 * silc_server_remove_channel_user now broadcasts the received
483 Remove Channel User packet if it is not broadcast packet already.
484 The router must broadcast to inform other routers about removed
487 * Added users field into SilcPacketContext that is a reference count
488 of the context. One can increase the reference count by calling
489 silc_packet_context_dup which is now changed to just increase the
490 reference count instead of duplicating the data. The reference
491 count is decresed by calling silc_packet_context_free that will
492 free the data after the reference count hits zero.
494 For now on the packet context and everything allocated into it
495 (including the raw packet from network) must be freed by calling
496 the new silc_packet_context_free function. Added also new function
497 silc_packet_context_alloc that must be used now to allocate the
498 context. This also means that if a routine is asynchronous from
499 silc_[client/server]_packet_parse_type the packet context must
500 be duplicated by calling silc_packet_context_dup. Otherwise it
501 gets free'd after silc_[client/server]_packet_parse_type returns.
502 Also, one must remember that if packet is duplicated then its
503 reference count must be decresed by calling the free function as
504 many times as it was duplicated.
506 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
507 from both client and server.
509 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Made joining to a channel working in router environment.
513 * Cleaned up JOIN command on server side and create function
514 silc_server_command_join_channel internal routine to make the
517 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Changed silc_command_pending list to SilcDList. Also, added
520 `ident' field to SilcServerCommandPending structure to identify
521 the reply and to call correct callback.
523 Added silc_server_command_pending_check function to replace the
524 corresnponding macro. The silc_command_pending list is not
527 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
528 to set identifier to previously allocated Command Payload. It
529 is used to set identifier for command when resending Command
532 * Added silc_command_payload_encode_payload to encode Command
533 Payload buffer from SilcCommandPayload structure.
535 * Added silc_argument_payload_encode_payload to encode Argument
536 payload buffer from SilcArgumentPayload structure.
538 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Changed WHOIS command to support router connection on server side.
541 The whois request is always sent to router unless the server is
542 standalone server. After server has received the reply from the
543 router will it send the reply to the client.
545 * Added silc_server_packet_broadcast into silcd/server.[ch] to
546 broadcast received broadcast packet. The function is used only
547 by router. The broadcast packet is always sent to the router's
550 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
551 render given ID to printable string, for log files for example.
553 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
555 * Made basic router to router connections working. At least they
556 can now connect to each other but nothing really works the way
557 they are supposed - yet.
559 * Added new initiator token to RouterConnection configuration
560 file in silcd/serverconfig.[ch]. It is used to tell whether we
561 are the initiator to the remote router or whether we'll expect
562 the other end to connect.
564 * Moved registering of listener task to silc_server_init, hence
565 the server starts listenning as soon as it is run, even if it
566 does not have connections to other routers. Let's see how well
569 * Changed default connection retry timeouts for more suitable in
572 * Removed cipher and such arguments from silc_idlist_add_client
573 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
574 Added new function silc_idlist_add_data to add the keys and stuff
577 * Added SilcIDListData structure and added it to SilcClientEntry
578 and SilcServerEntry as their first field in the structure. This
579 way we can explicitly cast the ID entries to the SilcIDListData
580 structure and get common data for the entries. In past, we had
581 to first check what type of connection it is and then cast it to
582 correct ID entry type. Now, we can directly cast the opaque
583 pointer to the SilcIDListData (no matter what ID entry it actually
584 is) and get the data needed.
586 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
588 * Wow, found a bug in scheduler. The scheduler uninitialized itself
589 in some circumstances even if threre were timeout tasks, though not
590 IO tasks, but tasks anyway. Now fixed.
592 * Defined SilcServerConnection structure to hold connection specific
593 stuff about directly connected servers and routers. The definition
594 is currently in silcd/server_internal.h. I thought about having
595 a bit more important role fro this struct but for now it is used
596 only when connecting to other server (or router actually).
598 * Added connecting retry support in server when connecting to
599 router(s). The retry feature implement exponential backoff
600 algorithm. Also, added SilcServerParams structure to hold default
601 parameters for server. For now, it include these retry settings
602 and are hard coded. After server is moded to be as Silc Server
603 Library this structure will be more important.
605 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Changed client librarys channel->clients table to SilcList and
608 changed code accordingly.
610 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Changed client's channel table to SilcList and changed code
613 accordingly. Also changed SilcChannelClientEntry to include back-
614 pointer to the channel so that client entry can use that structure
615 as list as well and we have fast cross-reference to the channel.
616 This change dramatically decreased the complexity of channel
617 handling with client entry and vice versa (removed one extra
618 loop when searching for channel entry from many functions).
620 * Changed server->sim from table to SilcDList and changed code
623 * NAMES command can now be used from user interface. It will show
624 the user list on the channel, neatly.
626 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
627 Code now saves realname of the user if it becomes available.
629 * Renamed configure.in to configure.in.pre and made ./prepare
630 script to automatically add correct version string to
631 configure.in which it creates from configure.in.pre.
633 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
635 * NAMES command reply now shows users mode with the nickname when
638 * Moved silc_client_ch[u]mode[_char] functions from
639 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
640 place sucks, they are utility functions and should be in some
643 * Fixed some unsigned int's to unsigned short's. Patch by cras.
645 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
648 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Added TRQ (efficient deque and list library) into lib/trq. This is
653 a very good list library that is currently used in the SILC. Defined
654 SilcList API over the library because I didn't like the API very
655 much. See lib/trq/silclist.h for the API and examples of how to
656 use the API. Fixed various places in the code to use the new
657 SilcList API. The SilcList is meant for lists that has a structure
658 already defined as a list. It is not suitable to add just some
659 context to the list (in TRQ, the context is the list actually).
661 So, I defined SilcDList that can be used for the purpose where
662 predefined list structure does not exit. This can be used as
663 such list. Now some context just can be added to the SilcDList.
664 Currently this list is not used in the SILC just yet, though there
665 are a lot places where this can replace dynamically allocated
666 tables and I will fix these places, later, to use SilcDList.
667 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
668 and use TRQ internally).
670 Also fixed some annoying warning messages that the original TRQ
671 code generated. Also minor changes to TRQ's Makefile.in.
673 * Added support for querying by Client ID to both WHOIS and
674 IDENTIFY commands into server, as required by the protocol.
676 * Removed method function pointers from SilcBuffer structure. They
677 weren't used to anything and just increased the context size for
678 no good reason. This change also made silc_buffer_alloc and
679 silc_buffer_free functions inline functions.
681 * Disabled command flooding detection support until it's fixed so
682 that it accepts commands in but does not execute them more than once
685 * Added silc_net_localhost(), to return local hostname, into
686 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
687 that must be initialized before calling silc_client_init.
689 * Added new function: silc_server_send_notify_on_channels to send
690 notify messages to all channels client has joined. It is assured
691 that the message is sent only once per client.
693 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
694 lib/silcutil/silcutil.[ch] as silc_format function. The new
695 function is generic and is used by server as well, not only by
696 the logging routines.
698 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
699 the provided version string was not acceptable. Added new function:
700 silc_ske_check_version into lib/silcske/silcske.h. The function
701 must be implemented by the application (client or server) and it
702 does not reside in the SKE library. The function checks the version
703 string remote end sent.
705 * Added back pointers (to opaque context and to SilcSocketConnection)
706 into SilcPacketContext structure into lib/silccore/silcpacket.h.
708 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
709 duplicate packet context structure.
711 * Changed `notify' client operation to send same arguments as client
712 receives from server except for ID's. ID's are mapped to correct
713 ID entry and that is returned. Also, if channel entry is not sent
714 by server but the notify is for channel the channel entry is sent
715 to application (otherwise application doesn't know that it is for
716 channel (library gets it from packet's Destination ID)).
718 * Added silc_client_remove_from_channels into client library to
719 remove a client from all channels it has joined to. Used when
720 received SIGNOFF notify from server. Added also new function
721 silc_client_replace_from_channels to replace old ID entry with
722 new ID entry on all channels. Used when received NICK_CHANGE
725 * Fixed ID Cache list handling in silc_idlist_get_client in
726 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
727 to get (or query) client by ID.
731 * Added connection authentication status message defined by the
732 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
733 support for these into the code in client and server side.
735 * Added generic function silc_client_send_command to send any command
736 with variable argument list. Application should use this function
737 to send commands if the command functions provided by the library
738 does not suite for the application's user interface needs.
740 * Added new `failure' client operation. Application is notified about
741 received failure packet if client is executing a protocol. In this
742 case the protocol's execution has failed.
744 * Added SKE's end notify to send the SKE_SUCCESS notify message that
745 is required by the protocol.
747 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
748 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
751 * Added status flag to SilcSKE object to indicate realtime status
754 * Application receives now exactly same command reply arguments as
755 the library receives from server. However, if ID is received the
756 corresponding ID entry is returned to the application (eg. Client
757 ID is mapped to correct SilcClientEntry entry and that is returned).
758 Changed command_reply client operation due to this change.
760 * Changed all ID's in commands and in command replys as ID Payloads.
761 Change affected both client and server side codes.
763 All ID's sent in SILC network (with execption of ID's in SILC
764 Packet header) are sent in ID Payload to support variable length
767 * Server now notifies nick changes and notifies all clients on
768 the channels about the new nickname (about the new Client ID,
771 * Implemented CMODE command to change channel modes. Supports all
772 channel modes defined by the protocol specs except ban and invite
773 lists. (Also, private channel key mode is supported but support for
774 setting private channel key in client is missing, thus, this mode
775 has no effect on client side (except that server requires that the
776 client uses private channel key and normal channel traffic does not
779 Also, invite mode works per se, but INVITE command does not work
780 yet correctly, so you can set channel as invite only channel but
781 inviting clients to the channel does not work (it is yet to be
782 thought what's the best way to do it).
784 * Added new command SILC_COMMAND_CUMODE to change user mode on the
785 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
786 Implemented CUMODE command to change user's mode on the channel.
787 Supports all modes defined by the protocol specs.
789 * Added NAMES command reply to return users modes on the channel.
791 * Removed unnecessary and slow ciphers from lib/silccrypt.
793 * Set SO_KEEPALIVE option to connection sockets by default.
795 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
797 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
798 redefined the Notify Payload into protocol specs.
800 * Added silc_id_payload_parse_id to get ID directly from raw
803 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
806 accept searching by Client ID as well.
808 * Added support for LEAVE and SIGNOFF notify types in client library.
810 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
811 to parse ID Payload from raw data.
813 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Added flags parameter into silc_ske_assemble_security_properties
816 function in lib/silcske/silcske.[ch].
818 * Changed notify client operation to fit better for notify messages
819 sent by server. The notify payload received from server is now
820 passed to the application (after parsing it to SilcNotifyPayload).
821 It is application's responsibility to retrieve the arguments
822 from the payload and show the message the way it wants. The message
823 sent by server is implementation specific.
825 * Changed public keys to comply with the protocol specification.
826 Old public keys are not supported anymore and are not compatible.
828 * Removed nickname from Channel Payload as the latest draft removed
829 it. The client must resolve the nickname from the NAMES command
830 reply received when it joined the channel.
832 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
834 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Fixed some errors in protocol specification drafts.
838 * Created lib/silccore/silcnotify.c to implement Notify Payload
839 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
840 generic payloads described by protocol specifications. The file
841 includes implementations for ID Payload and Argument Payload.
843 * Changed Command Payload implementation to use the new Argument
844 Payload. Changed command_xxxx_payload to command_payload_xxxx
845 to comply with SILC coding conventions.
847 * Added suppport for Argument Payload handling in Notify Payload
848 implementation as protocol requires it. Added the new support
849 into server and client lib as well.
851 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
853 * Added support for multiple nicknames on same channel. [n] is
854 added locally to the nickname if there are more than one same
855 nicknames on the channel.
857 * Server now sends all nicknames that matched WHOIS request.
858 Client also shows the list received from server.
860 * Added TOPIC command to client side. User can now set and show
861 current topic on channel.
863 * Added MOTD command to client and server. Also, server sends the
864 motd when client connects to the server.
866 * Changed version strings to comply ISO 8601.
868 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Fixed protocol error handling in client library. It should now
871 cope even if the SKE fails for some reason.
873 * Made new protocol specification drafts for submitting to IETF.
875 * Implemented TOPIC command to server in silcd/command.c.
877 * Added two new notify types into lib/silccore/silcnotify.h:
878 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
879 notify nickname change and topic setting/change on a channel.
881 * API change of command_reply operation in client library. The
882 application gets now the status type received from server as well.
884 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Removed the function just added to lib/silcutil/silcschedule.[ch].
888 * Cras fixed and optimized the packet handling even further and
889 it should work now. Minor change to the prototype of function
890 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
892 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Added new function into lib/silcutil/silcschedule.[ch]:
895 silc_schedule_with_fd to select() a specified fd. The function
896 returns after timeout expires or data arrives or goes. The
897 function is used by packet routines to wait that all data is
898 received from network.
900 * Fixed data reading from network in lib/silccore/silcpacket.c.
901 The code now assures that all data is read from the fd and then
902 continues packet processing. This was a bug fix since the code
903 used to drop some data in some circumstances.
905 * Added new function into lib/silcclient/client.[ch]:
906 silc_client_start_key_exchange to start key exchange after
907 connection has been established to server. The code internally
908 now uses this funtion but its main purpose was to provide it
909 for applications that perform their own connecting. After
910 application has created a connection it merely calls this
911 function to start the key exchange between client and server.
912 The library takes care of everything else after that.
914 Updated also lib/silcclient/README to explain the usage of
917 * Do not send to application information that connection has
918 been established. Application gets notified it by connect
921 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
923 * Applied cras's patch to add silc_schedule_one function. The
924 function runs scheduler once and returns.
926 * Fixed the scheduler after cras messed it up. The timeout
927 handling works now as it's supposed to work.
929 * Added into lib/silccore/ silcnotify.h to include notify
930 message types support. Changed silc_server_send_notify*
931 functions, in server.[ch], to support those new notify types.
932 Added the support for the notify types into client library,
933 as well. Added new notify client operation into ops.h in
936 * Changed silc_server_packet_send_to_channel to send normal
937 packets instead of just channel message packets. The function
938 is now used to send the notify packets to channels. It is not
939 used to send channel message packets anymore, as server never
942 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
943 va_arg()s as it seems to require it nowadays. I guess, if SILC
944 is compiled with older va_arg() the new code should work anyway.
946 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Splitted core library. Core library (lib/silccore) includes
949 now only SILC protocol specific core (and common) components.
950 Created new utility library (lib/silcutil) that includes more
951 generic purpose stuff. The stuff for util library was taken
952 from the old core library. This was minor and easy split.
954 * Created SILC Client Library (lib/silcclient) that includes
955 implementation of the SILC client without user interface. This
956 was major move from silc/ directory. The code has been changed
957 so that it is transparent towards the user interface. The
958 silc/ directory includes now the same user interface as before
959 and it uses the new client library. Read lib/silcclient/README.
960 Basicly, the client library performs everything else related
961 to SILC except user interface handling. Also, configuration
962 files are considered to be part of user interface and library
963 does not handle them.
965 This change also changed a lot of structures, function naming etc.
966 Most important change was that SilcClientWindow object was
967 renamed to SilcClientConnection in the client library. Created
968 also new file lib/silcclient/ops.h. Also added new files
969 silc/local_command.[ch] and silc/client_ops.[ch].
971 All these changes were made to make it easier for user interface
972 designers to create what ever user interface for the SILC client
975 It is also expected that the server will be moved to lib
976 directory as well and SILC Server Library will be created;
977 sometimes in the future.
979 * Removed Local commands from lib/silccore/silccommand.h as
980 they are application specific and new client library does not
981 handle any of those anymore.
983 * Several functions moved to lib/silcutil/silcutilc.[ch] from
984 old client implementation in silc/.
986 * Added support for callback functions in SILC_LOG_* macros.
987 Application can now set its own callbacks that will be called
988 instead of using the default functions that will always print
989 the debug messages to stderr (or stdout). Also, debugging can
990 now be disabled by setting silc_debug to FALSE and re-enabled by
991 setting it to TRUE. Note, that logging will still work even
992 if debugging is disabled.
994 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
995 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
996 silc_log_reset_debug_callbacks.
998 * To enable debugging in silc client one must give now -d
999 option on command line.
1001 * Changed silc_schedule_init to automatically allocate task queues
1002 if they are not allocated before calling it.
1004 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Added GMP 3.1 into math library.
1008 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1010 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1011 a channel in SILC network. The packet is used by servers and
1012 routers to notify other routers that user has left a channel.
1013 This little feature was missing until now. Added the feature
1014 to protocol specification as well.
1016 Added functions: silc_server_send_remove_channel_user and
1017 silc_server_remove_channel_user into server.[ch].
1019 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1020 lib/silccore/silcpacket.h. However, they are not implemented
1023 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1025 * Fixed joining to a channel and sending channel messages
1026 between server and router. The channel message sending should
1027 now work inside a cell.
1029 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Fixed the private message sending between server and router.
1032 The private message sending should now work inside a cell.
1034 * Added silc_server_replace_id into server.[ch] to replace
1035 existing ID in the SILC network.
1037 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1038 and silc_idlist_replace_server_id into idlist.[ch] in server.
1040 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Fixed the server to server connections. Server can again now
1043 connect to router. Router to router connections probably does
1046 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Added dynamic protocol registering support. Now protocols can
1049 registered and unregistered on the fly. Patch by cras.
1051 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Added lib/contrib directory to hold routines that some platforms
1054 don't have but are needed by SILC.
1056 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1057 into lin/contrib to provide getopt() and getopt_long() for
1058 those who don't have it.
1060 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1062 * Added AWAY command to client. When away message is set and
1063 client receives a private message packet the client automatically
1064 replies to the sender with the away message.
1066 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1067 bug seemed to be the cause of recent problems when compiling
1070 * Added version detection support to SKE protocol specification
1071 and added the new changes to the SKE implementation as well.
1072 There were other minor changes in the SKE protocol as well.
1074 Many changes in lib/silcske/silcske.[ch] and in
1075 lib/silcske/payload.[ch].
1077 * Added ^U functionality, clear input line. Patch from cras.
1079 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * Mainly small bugfixes on core library. Fixed some debugging
1082 logging and buffer overflow in silclog.c.
1084 * Updated config.sub and config.guess on the distribution tree.
1086 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Added command lagging support in server. Client may execute
1089 commands now only once in two seconds.
1091 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Optimized packet reception. MAC computation and checking is now
1094 also more optimized. A lot previously duplicated code is now
1095 used as generic by both client and server.
1097 * Fixed key pair generation in clientutil.c
1099 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Added into lib/silccore/silcbufutil.[ch] new function;
1102 silc_buffer_realloc.
1104 * Moved generic packet sending/encryption functions to
1105 lib/silccore/silcpacket.[ch] from client and server. Some
1106 rewriting of the functions.
1108 * Moved all generic packet reception/decryption functions to
1109 lib/silccore/silcpacket.[ch] from client and server. The
1110 packet processing is now much cleaner in both client and server.
1111 These were major changes in both client and server.
1113 * Created many common functions in server to do packet sending.
1114 Previously code were duplicated a lot, this has been removed
1117 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1119 * Rewrote major parts of the ID cache system. Don't know
1120 whether it is better now or not but at least the API is more
1123 * Major rewrite on ID cache stuff on client because of the ID
1124 cache API changes. Added idlist.c to client.
1126 * Also major rewrite on ID cache stuff on server as well.
1127 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1128 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1129 in hand, instead they are all put into the ID cache system now.
1130 All server_idlist_* routines uses ID cache now instead of
1131 traversing its own lists (those lists does not exist anymore).
1132 SilcIDList though still exists. Also, SilcXXXEntry's are
1135 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Finally made the SKE implementation compliant to the protocol
1138 specification. All mp integers are now binary encoded as
1139 opposed being HEX encoded.
1141 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1144 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1145 functions: silc_[encode/decode]_pem. Also added function
1146 silc_encode_pem_file to PEM encode with newlines ('\n') for
1149 * SILC public keys are now encoded either PEM or binary. Same
1150 option is for private keys as well. By default private keys
1151 are binary encoded and public keys PEM encoded. Silly HEX
1152 encoding were removed.
1154 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1155 function to create fingerprints.
1157 * Fixed a bug in SHA1; does not change the original data anymore.
1159 * Partly implemented INFO command on client and server side.
1160 Fixed CLEAR command. Changes to SERVER command; show current
1161 server(s) when giving command without arguments. Added
1162 VERSION command to client.
1164 * Added check to server that unregistered connections cannot
1165 execute commands (unless it is specificly allowed).
1167 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1169 * Fixed screen refresh.
1171 * Fixed channel joining bug from client. On some circumstances
1172 client tried to join to a channel it had already joined.
1174 * Added public key verification process into client's protocol.c.
1175 The client now verifies the public key from user and saves
1176 it into ~./silc/serverkeys/ directory.
1178 Added into: clientutil.[ch]: silc_client_verify_server_key.
1180 * Changed SKE protocol's silc_ske_initiator_finish function
1181 to accept callback function that verifies the received public
1182 key. Removed old silc_ske_verify_public_key function.
1184 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1187 silc_pkcs_private_key[_data]_set.
1189 * Made the password and public authentication more cleaner in
1190 server's protocol.c.
1192 * Removed historic and obsolete protocol `channel_auth' from
1193 both client and server.
1195 * Removed wrong way of sending command status messages from
1196 server to client in server's command.c. The old way violated
1197 protocol specification.
1199 Changes to silccore/silccommand.[ch]: removed
1200 silc_command_encode_status_payload -> not needed anymore,
1201 changed silc_command_encode_payload_va to accept extra
1202 argument on variable argument list. The argument type must
1203 now be provided to the function. Also, added new function:
1204 silc_command_encode_reply_payload_va which is same as
1205 normal command_encode_payload_va except command status type
1206 is provided as extra argument.
1208 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Added ~./silc directory handling. The directory includes the
1211 public and private keys for the client.
1213 Added silc_client_check_silc_dir, silc_client_create_identifier
1214 and silc_client_load_keys.
1216 * Implemented SILC protocol compliant public key. Added public
1217 and private key saving to and loading from files.
1219 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1220 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1221 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1222 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1223 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1225 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1226 silc_pkcs_load_[public/private]_key.
1228 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added silc_server_get_route (route.[ch]) to get connection
1231 data for the fastest route for given ID.
1233 * Implemented INVITE command on client and server. The command
1234 were re-defined in the SILC Protocol Specification and the
1235 implementation now complies with the specification.
1237 * Implemented PING command on client and server.
1239 * Implemented NAMES command on client and server. The server side
1240 supports currently only normal server not router server yet.
1241 Some changes to NAMES definition in SILC protocol specification.
1243 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Implemented LEAVE command on client and server.
1247 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1248 again. This change was made to the protocol as well. Server
1249 should not violate the protocol specification anymore.
1251 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1253 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1254 was tested. SOCKS4 was not but should work anyway.
