1 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added reconnection support to server if the normal server looses
4 its connection to the router (for example if router is rebooted).
5 The server performs normal reconnection strategy implemented
6 to the server. Affected file silcd/server.c.
8 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
10 * Added new packet type SILC_PACKET_SET_MODE that is used to
11 distribute the information about changed modes (for clients,
12 channels and clients channel modes) to all routers in the
13 network. Updated the protocol specification accordingly.
15 Added functions into silcd/packet_send.c and
16 silcd/packet_receive.c: silc_server_send_set_mode,
19 Added new files silcmode.[ch] into lib/silccore that implements
20 the encoding and decoding of Set Mode Payload. Added new type
21 SilcSetModePayload. Moved the definitions of different modes
22 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
24 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Oops, a little mistake in server's connection authentication
27 protocol. The protocol is not ended with FAILURE but with
28 SUCCESS if the authentication is Ok. :) Affected file is
31 * Implemented NICK_CHANGE notify handling in server in the file
32 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
33 the local clients on the channel. After the changing nickname
34 in router environment snhould work and the [<unknown>] nickname
35 should appear no more.
37 The silc_server_replace_id function that receives the Replace ID
38 payload now sends the NICK_CHANGE notify type also in the file
39 silcd/packet_receive.c
41 * Changed WHOIS and IDENTIFY command to support the maximum amount
42 of arguments defined in protocol specs (3328 arguments). This
43 fixed a bug that caused problems when there were more than three
46 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Added extra parameter, command identifier, to the
49 silc_client_send_command so that explicit command identifier
52 Changed that ID list routines uses specific command identifier
53 when sending WHOIS/IDENTIFY requests to the server so that they
54 can be identified when the reply comes back.
56 Affected files lib/silcclient/command.[ch],
57 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
59 * Added `sender' argument to silc_server_packet_send_to_channel
60 to indicaet the sender who originally sent the packet to us
61 that we are now re-sending. Ignored if NULL. Affected file
62 silcd/packet_send.[ch].
64 * Added some server statistics support in silcd/server_internal.h
65 SilcServerStatistics structure and around the server code. Also
66 send some nice statistics information when client is connecting
69 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
71 * Fixed channel ID decoding in server's JOIN command reply in
74 * Fixed braodcasting of replace ID payload to not to send it if
75 we are standalone server in silcd/packet_receive.c.
77 * Fixed all channel message sending routines to not to send
78 packets to clients that has router set, since they are routed
79 separately in the same function earlier. Affects file
80 silcd/packet_send.c and all channel packet sending functions.
82 * In USERS reply, res_argv[i] are not allocated, the table
83 is allocated. Thus changed that free the table, not its
86 * In server's whois_check and identify_check if the client is
87 locally connected do not send any WHOIS commands - they are not
90 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Fixed some minor bugs in client when sending WHOIS command. The
93 arguments was in wrong order.
95 * Removed statis function add_to_channel from server in
96 silcd/command.c that was previously used with the joining but
99 * Tested USERS command in router environment successfully with two
100 routers, two servers and two clients.
102 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
104 * Reorganized the USERS command and command reply in client library
105 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
106 When the command is given by user we register a pending command
107 callback that will reprocess the command after the reply has been
108 received from the server. When reprocessing the packet we then
109 display the information. Thus, the USERS information is displayed
110 now in the command callback instead of in the command reply
111 callback. The processing of the command is same as previously
112 when server has sent the command reply in the JOINing process.
114 * Added to USERS command in silcd/command_reply.c to join the client,
115 we didn't use to know about, to the channel after we've created
116 a client entry for it. Also, for clienet we did know already still
117 check whether it is on the channel or not and add it if not.
119 * Removed silc_server_command_join_notify as the function and its
122 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Changed the client's pending command handling to the same as the
125 server's pending command handling. It is also now possible to
126 execute command reply functions from other command reply
127 function as the function callbacks for commands and command
128 replies are one and same. The pending commands are not static
129 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
130 in client connection context. Thus, pending commands are server
131 connection specific as it is convenient.
133 Changed the function silc_client_command_pending and
134 silc_client_command_pending_del and added new function
135 silc_client_command_pending_check. Removed the
136 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
139 * Added cmd_ident, current command identifier, to the client
140 connection context in lib/silcclient/client.h to keep track on
141 command identifiers used in command sending. Client's command reply
142 function handling now supports the mandatory command identifiers.
144 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
145 funtions in client to fully support pending command callbacks.
147 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
148 as one of the arguments to the application in the command reply
151 * NOTE: The FORWARDED flag is depracated. It used to be depracated
152 before first releasing SILC but came back. Now it is removed again
153 and should come back nomore. The FORWARDED flag was used only
154 by the JOINing procedure by forwarding the command packet to router.
155 Now, the JOINing procedure has been changed to more generic (due
156 to various router environment issues) and FORWARDED is not needed
157 anymore for anything. The protocol specification is yet to be
160 Now, removed silc_server_packet_forward from server and the flag
161 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
163 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Renamed NAMES command to USERS command. The NAMES was named that
166 due to historical reasons. Now it is renamed. Also, rewrote
167 parts of the USERS command. The nickname list is not sent anymore
168 by the server. Only Client ID and mode lists are sent in the USERS
169 command. Changed this also to the protocol specification.
171 The client now resolves the names and stuff after it receives
172 the USERS list from the server when joining to the channel.
174 * WHOIS and IDENTIFY commands has been changed to support multiple
175 Client ID's per command. One can now search for multiple users
176 in the network by sending only one WHOIS or IDENTIFY command.
177 Changed the code and the protocol specifications.
179 * Removed silc_server_command_identify_parse and changed that IDENTIFY
180 uses silc_server_command_whois_parse to parse the request. */
182 * If normal server, do not parse the WHOIS and IDENTIFY requests
183 before sending it to the router. Saves some time.
185 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Fixed JOIN command on client library. Wrong number of arguments
188 used to crash the client.
190 * Added silc_server_channel_has_global function to check whether
191 channel has global users or not.
193 * Added silc_server_channel_has_local function to check whether channel
194 has locally connected clients on the channel.
196 * The silc_server_remove_from_one_channel now checks whether the
197 channel has global users or not after given client was removed from
198 the channel. It also checks whether the channel has local clients
199 on the channel anymore. If it does not have then the channel entry
200 is removed as it is not needed anymore.
202 * The silc_server_notify now checks on JOIN notify whether the joining
203 client is one of locally connected or global. If it is global then
204 the channel has now global users on the channel and that is marked
205 to the channel entry. Also, it now saves the global client to
206 global list who is joining and JOINs it to the channel. This is
207 for normal server, that is.
209 Changed silc_server_send_notify_on_channel,
210 silc_server_packet_relay_to_channel and
211 silc_server_packet_send_to_channel check if we are normal server
212 and client has router set (ie. global client) do not send the
213 message to that client, as it is already routed to our router.
215 * Implemented LEAVE notify type handling in silc_server_notify
218 * Tested LEAVE command in router environment successfully. Tested
219 with two routers, two servers and two clients.
223 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
225 * Implemented SIGNOFF notify type handling in silc_server_notify
228 * silc_server_remove_id now removes the client entry from all channels
229 it has joined and thusly sends SIGNOFF notify type.
231 * Rewrote the NAMES list generation in server by removing two excess
232 loops. The lists are created now inside one loop.
234 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * silc_server_remove_channel_user checks now also global list
237 for channel and client.
239 * silc_server_new_channel_user checks now both local and global
240 list for channel and client. Fixed a bug in client id decoding.
241 Used to decode wrong buffer.
243 * silc_server_channel_message checks now both local and global
244 list for channel entry.
246 * Tested channel joining (hence JOIN) in router environment
247 successfully. Tested with two routers, two servers and two
250 * Tested channel message sending in router environment successfully.
252 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Added silc_server_save_channel_key into server.[ch] to save the
255 received channel key in Channel Key payload processing. It is
256 also used in JOIN command reply handling.
258 Equivalent function silc_client_save_channel_key added into
259 client.[ch] into client library.
261 * Changed JOIN command reply to send information whether the channel
262 was created or not (is existing already) and the channel key
263 payload. Changed protocol specs accordingly.
265 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
266 the request was sent by ID and not by nickname. Crashed on
269 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
272 now correctly save the received data.
274 * silc_server_free_sock_user_data now notifies routers in the
275 network about entities leaving the network.
277 At the same time implemented functions silc_server_remove_id
278 and silc_server_send_remove_id to receive and send REMOVE_ID
279 packets. The packet is used to notify routers in the network
280 about leaving entities. The ID removed will become invalid in
283 * Added function silc_idlist_del_server into server. Removes and
284 free's server entry from ID list.
286 * silc_server_private_message function now checks, if we are router,
287 that the destination ID really is valid ID, naturally.
289 * In router when NEW_ID packet is received (for new client) the
290 hash of the Client ID is saved in the ID Cache but the
291 client->nickname is set to NULL, instead of putting the hash
294 IDENTIFY command now also checks that client->nickname must be
295 valid. If it is not if will request the data from the server who
296 owns the client. Added new function
297 silc_server_command_identify_check.
299 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
300 to set the command to already allocated Command Payload.
302 * Tested private message sending in router environment with two
303 routers, two servers and two clients. Fixed minor bugs and now
306 * Fixed segfault from client's NAMES command. Used to crash if
309 * Forwarded packets must not be routed even if it is not destined
310 to the receiver. Changed server code comply with this.
312 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Added `require_reverse_mapping' boolean value to ServerParams
315 structure. If TRUE (not default) the server will require that
316 the connecting host has fully qualified domain name.
318 If the reverse mapping is not required and hostname could not be
319 found the IP address is used as hostname.
321 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
323 * Implemented version string checking to both client and server.
324 The check is incomplete currently due to the abnormal version
325 strings used in development version of SILC.
327 * Changed all command functions in server to use the new
330 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
332 * Changed char *data to unsigned char *data in ID Cache system to
333 support binary data as ID Cache data. Changed code to support
334 binary data in lib/silccore/idcache.c.
336 * Renamed silc_server_packet_relay_command_reply to
337 silc_server_command_reply as it is normal packet receiving
338 function. Rewrote the function to accept command replys for
339 servers and not only for clients.
341 * Mark remote router always as registered server if we are connecting
342 to it. Otherwise, commands sent by the router to us are ignored.
344 * All ID List find routines now returns the ID Cache Entry pointer
345 as well if requested.
347 * WHOIS command works now in router environment, tested with two
348 routers, two servers and two clients.
350 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
351 in router environment (as it is almost equivalent to WHOIS) but
352 hasn't been tested thoroughly. Added new functions:
354 silc_server_command_identify_parse
355 silc_server_command_identify_send_reply
356 silc_server_command_identify_from_client
357 silc_server_command_identify_from_server
359 * Disabled route cache adding because adding two different ID's with
360 same IP replaces the old cache entry thus giving wrong route.
361 The entry->router->connection is always the fastest route anyway
362 so route cache may not be needed. Of course, new routes maybe
363 established after receiving the ID when the entry->router->connection
364 might not be anymore the most optimal.
366 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * Add route cache for received ID for fast routing.
370 * Added silc_server_packet_route to route received packet on router
371 that is not destined to us.
373 * Renamed silc_server_get_route to silc_server_route_get.
375 * Added id_string and id_string_len fields into SilcServer to
376 include encoded ServerID for fast comparing without excess
377 encoding of the ID's.
379 * Cleaned up WHOIS command on server side. Added following static
382 silc_server_command_whois_parse
383 silc_server_command_whois_check
384 silc_server_command_whois_send_reply
385 silc_server_command_whois_from_client
386 silc_server_command_whois_from_server
388 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
389 arguments in command replies. All command functions should be
390 updated to use this macro.
392 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Minor typo fixes on command reply handling on server.
396 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Added silc_server_command_add_to_channel internal routine to add
399 the client to the channel after router has created the channel and
400 sent command reply to the server.
402 * Added generic silc_server_send_command to send any command from
405 * Use static buffer with ID rendering instead of duplicating data.
407 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
409 * Fixed a channel user mode bug when joining to a channel server gave
410 everybody channel founder rights, oops.
412 * We mark ourselves as the router of the incoming server connection
413 if we are router ourselves. This way we can check in some packet
414 sending functions whether it is locally connected server. For
415 incoming router connections we put NULL.
417 * For router sending packets locally means now always sending the
418 packet cell wide; to local clients and local servers. For normal
419 server sending packet locally means sending it to only local
422 * Fixed the JOIN command to really work in router environment. If the
423 channel is created it is always created by the router. Router is
424 also responsible of making the initial joining to the channel,
425 sending JOIN notify to the sending server and distributing
426 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
427 does not exist server doesn't do anything else but forward the
428 command to the router which performs everything.
430 * Added silc_server_send_channel_key function to send the Channel Key
433 * Added silc_server_create_channel_key to create new channel key. The
434 channel key is now re-generated everytime someone joins or leaves
435 a channel, as protocol dictates. Note: channel->key_len is the
438 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Splitted server.[ch] finally. Created now packet_send.[ch] and
441 packet_receive.[ch] to separate packet sending and receiving
442 routines. The server.[ch] now includes everything else including
443 actual packet processing (writing and reading data) and other
446 Renamed silc_server_private_message_send_internal to
447 silc_server_send_private_message. The routine is still though
448 used only to relay private messages as server does not send
449 private messages itself.
451 Renamed silc_server_new_channel to silc_server_create_new_channel
452 and added new function sicl_server_new_channel that handles the
453 incoming New Channel packet. Added also new sending function
454 silc_server_send_new_channel to send New Channel Payload.
456 * Added new function silc_server_notify to process incoming notify
457 packet to the server/router. Server may then relay the notify
458 to clients if needed.
460 * Added new function silc_server_new_channel_user to process incoming
461 New Channel User packet. Router will redistribute the packet and
462 send JOIN notify to its local clients and locally connected servers
463 if needed. Normal server will send JOIN notify to its local client
464 on same channel when received this packet. Added also corresponding
465 sending function silc_server_send_new_channel_user to sent the
468 * Added boolean route argument to send_notif_to_channel and
469 packet_send_to_channel functions to attempt to route the packet
470 if it is TRUE and send only locally if it is FALSE.
472 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * silc_server_replace_id now broadcasts the received replace ID
475 packet if it is not broadcast packet already. The router must
476 broadcast to inform other routers about changed ID.
478 * Added backpointer to server's router into SilcServer context in
479 silcd/server_internal.h.
481 * Fixed silc_server_packet_broadcast to send correct broadcast
484 * The channel key is now distributed to the local client as soon
485 as it is received from the router (in router environment) so that
486 no other packet may be sent for the channel until client has
489 * silc_server_remove_channel_user now broadcasts the received
490 Remove Channel User packet if it is not broadcast packet already.
491 The router must broadcast to inform other routers about removed
494 * Added users field into SilcPacketContext that is a reference count
495 of the context. One can increase the reference count by calling
496 silc_packet_context_dup which is now changed to just increase the
497 reference count instead of duplicating the data. The reference
498 count is decresed by calling silc_packet_context_free that will
499 free the data after the reference count hits zero.
501 For now on the packet context and everything allocated into it
502 (including the raw packet from network) must be freed by calling
503 the new silc_packet_context_free function. Added also new function
504 silc_packet_context_alloc that must be used now to allocate the
505 context. This also means that if a routine is asynchronous from
506 silc_[client/server]_packet_parse_type the packet context must
507 be duplicated by calling silc_packet_context_dup. Otherwise it
508 gets free'd after silc_[client/server]_packet_parse_type returns.
509 Also, one must remember that if packet is duplicated then its
510 reference count must be decresed by calling the free function as
511 many times as it was duplicated.
513 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
514 from both client and server.
516 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * Made joining to a channel working in router environment.
520 * Cleaned up JOIN command on server side and create function
521 silc_server_command_join_channel internal routine to make the
524 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Changed silc_command_pending list to SilcDList. Also, added
527 `ident' field to SilcServerCommandPending structure to identify
528 the reply and to call correct callback.
530 Added silc_server_command_pending_check function to replace the
531 corresnponding macro. The silc_command_pending list is not
534 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
535 to set identifier to previously allocated Command Payload. It
536 is used to set identifier for command when resending Command
539 * Added silc_command_payload_encode_payload to encode Command
540 Payload buffer from SilcCommandPayload structure.
542 * Added silc_argument_payload_encode_payload to encode Argument
543 payload buffer from SilcArgumentPayload structure.
545 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
547 * Changed WHOIS command to support router connection on server side.
548 The whois request is always sent to router unless the server is
549 standalone server. After server has received the reply from the
550 router will it send the reply to the client.
552 * Added silc_server_packet_broadcast into silcd/server.[ch] to
553 broadcast received broadcast packet. The function is used only
554 by router. The broadcast packet is always sent to the router's
557 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
558 render given ID to printable string, for log files for example.
560 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Made basic router to router connections working. At least they
563 can now connect to each other but nothing really works the way
564 they are supposed - yet.
566 * Added new initiator token to RouterConnection configuration
567 file in silcd/serverconfig.[ch]. It is used to tell whether we
568 are the initiator to the remote router or whether we'll expect
569 the other end to connect.
571 * Moved registering of listener task to silc_server_init, hence
572 the server starts listenning as soon as it is run, even if it
573 does not have connections to other routers. Let's see how well
576 * Changed default connection retry timeouts for more suitable in
579 * Removed cipher and such arguments from silc_idlist_add_client
580 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
581 Added new function silc_idlist_add_data to add the keys and stuff
584 * Added SilcIDListData structure and added it to SilcClientEntry
585 and SilcServerEntry as their first field in the structure. This
586 way we can explicitly cast the ID entries to the SilcIDListData
587 structure and get common data for the entries. In past, we had
588 to first check what type of connection it is and then cast it to
589 correct ID entry type. Now, we can directly cast the opaque
590 pointer to the SilcIDListData (no matter what ID entry it actually
591 is) and get the data needed.
593 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Wow, found a bug in scheduler. The scheduler uninitialized itself
596 in some circumstances even if threre were timeout tasks, though not
597 IO tasks, but tasks anyway. Now fixed.
599 * Defined SilcServerConnection structure to hold connection specific
600 stuff about directly connected servers and routers. The definition
601 is currently in silcd/server_internal.h. I thought about having
602 a bit more important role fro this struct but for now it is used
603 only when connecting to other server (or router actually).
605 * Added connecting retry support in server when connecting to
606 router(s). The retry feature implement exponential backoff
607 algorithm. Also, added SilcServerParams structure to hold default
608 parameters for server. For now, it include these retry settings
609 and are hard coded. After server is moded to be as Silc Server
610 Library this structure will be more important.
612 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Changed client librarys channel->clients table to SilcList and
615 changed code accordingly.
617 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Changed client's channel table to SilcList and changed code
620 accordingly. Also changed SilcChannelClientEntry to include back-
621 pointer to the channel so that client entry can use that structure
622 as list as well and we have fast cross-reference to the channel.
623 This change dramatically decreased the complexity of channel
624 handling with client entry and vice versa (removed one extra
625 loop when searching for channel entry from many functions).
627 * Changed server->sim from table to SilcDList and changed code
630 * NAMES command can now be used from user interface. It will show
631 the user list on the channel, neatly.
633 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
634 Code now saves realname of the user if it becomes available.
636 * Renamed configure.in to configure.in.pre and made ./prepare
637 script to automatically add correct version string to
638 configure.in which it creates from configure.in.pre.
640 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * NAMES command reply now shows users mode with the nickname when
645 * Moved silc_client_ch[u]mode[_char] functions from
646 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
647 place sucks, they are utility functions and should be in some
650 * Fixed some unsigned int's to unsigned short's. Patch by cras.
652 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
655 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Added TRQ (efficient deque and list library) into lib/trq. This is
660 a very good list library that is currently used in the SILC. Defined
661 SilcList API over the library because I didn't like the API very
662 much. See lib/trq/silclist.h for the API and examples of how to
663 use the API. Fixed various places in the code to use the new
664 SilcList API. The SilcList is meant for lists that has a structure
665 already defined as a list. It is not suitable to add just some
666 context to the list (in TRQ, the context is the list actually).
668 So, I defined SilcDList that can be used for the purpose where
669 predefined list structure does not exit. This can be used as
670 such list. Now some context just can be added to the SilcDList.
671 Currently this list is not used in the SILC just yet, though there
672 are a lot places where this can replace dynamically allocated
673 tables and I will fix these places, later, to use SilcDList.
674 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
675 and use TRQ internally).
677 Also fixed some annoying warning messages that the original TRQ
678 code generated. Also minor changes to TRQ's Makefile.in.
680 * Added support for querying by Client ID to both WHOIS and
681 IDENTIFY commands into server, as required by the protocol.
683 * Removed method function pointers from SilcBuffer structure. They
684 weren't used to anything and just increased the context size for
685 no good reason. This change also made silc_buffer_alloc and
686 silc_buffer_free functions inline functions.
688 * Disabled command flooding detection support until it's fixed so
689 that it accepts commands in but does not execute them more than once
692 * Added silc_net_localhost(), to return local hostname, into
693 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
694 that must be initialized before calling silc_client_init.
696 * Added new function: silc_server_send_notify_on_channels to send
697 notify messages to all channels client has joined. It is assured
698 that the message is sent only once per client.
700 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
701 lib/silcutil/silcutil.[ch] as silc_format function. The new
702 function is generic and is used by server as well, not only by
703 the logging routines.
705 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
706 the provided version string was not acceptable. Added new function:
707 silc_ske_check_version into lib/silcske/silcske.h. The function
708 must be implemented by the application (client or server) and it
709 does not reside in the SKE library. The function checks the version
710 string remote end sent.
712 * Added back pointers (to opaque context and to SilcSocketConnection)
713 into SilcPacketContext structure into lib/silccore/silcpacket.h.
715 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
716 duplicate packet context structure.
718 * Changed `notify' client operation to send same arguments as client
719 receives from server except for ID's. ID's are mapped to correct
720 ID entry and that is returned. Also, if channel entry is not sent
721 by server but the notify is for channel the channel entry is sent
722 to application (otherwise application doesn't know that it is for
723 channel (library gets it from packet's Destination ID)).
725 * Added silc_client_remove_from_channels into client library to
726 remove a client from all channels it has joined to. Used when
727 received SIGNOFF notify from server. Added also new function
728 silc_client_replace_from_channels to replace old ID entry with
729 new ID entry on all channels. Used when received NICK_CHANGE
732 * Fixed ID Cache list handling in silc_idlist_get_client in
733 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
734 to get (or query) client by ID.
738 * Added connection authentication status message defined by the
739 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
740 support for these into the code in client and server side.
742 * Added generic function silc_client_send_command to send any command
743 with variable argument list. Application should use this function
744 to send commands if the command functions provided by the library
745 does not suite for the application's user interface needs.
747 * Added new `failure' client operation. Application is notified about
748 received failure packet if client is executing a protocol. In this
749 case the protocol's execution has failed.
751 * Added SKE's end notify to send the SKE_SUCCESS notify message that
752 is required by the protocol.
754 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
755 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
758 * Added status flag to SilcSKE object to indicate realtime status
761 * Application receives now exactly same command reply arguments as
762 the library receives from server. However, if ID is received the
763 corresponding ID entry is returned to the application (eg. Client
764 ID is mapped to correct SilcClientEntry entry and that is returned).
765 Changed command_reply client operation due to this change.
767 * Changed all ID's in commands and in command replys as ID Payloads.
768 Change affected both client and server side codes.
770 All ID's sent in SILC network (with execption of ID's in SILC
771 Packet header) are sent in ID Payload to support variable length
774 * Server now notifies nick changes and notifies all clients on
775 the channels about the new nickname (about the new Client ID,
778 * Implemented CMODE command to change channel modes. Supports all
779 channel modes defined by the protocol specs except ban and invite
780 lists. (Also, private channel key mode is supported but support for
781 setting private channel key in client is missing, thus, this mode
782 has no effect on client side (except that server requires that the
783 client uses private channel key and normal channel traffic does not
786 Also, invite mode works per se, but INVITE command does not work
787 yet correctly, so you can set channel as invite only channel but
788 inviting clients to the channel does not work (it is yet to be
789 thought what's the best way to do it).
791 * Added new command SILC_COMMAND_CUMODE to change user mode on the
792 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
793 Implemented CUMODE command to change user's mode on the channel.
794 Supports all modes defined by the protocol specs.
796 * Added NAMES command reply to return users modes on the channel.
798 * Removed unnecessary and slow ciphers from lib/silccrypt.
800 * Set SO_KEEPALIVE option to connection sockets by default.
802 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
804 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
805 redefined the Notify Payload into protocol specs.
807 * Added silc_id_payload_parse_id to get ID directly from raw
810 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
813 accept searching by Client ID as well.
815 * Added support for LEAVE and SIGNOFF notify types in client library.
817 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
818 to parse ID Payload from raw data.
820 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Added flags parameter into silc_ske_assemble_security_properties
823 function in lib/silcske/silcske.[ch].
825 * Changed notify client operation to fit better for notify messages
826 sent by server. The notify payload received from server is now
827 passed to the application (after parsing it to SilcNotifyPayload).
828 It is application's responsibility to retrieve the arguments
829 from the payload and show the message the way it wants. The message
830 sent by server is implementation specific.
832 * Changed public keys to comply with the protocol specification.
833 Old public keys are not supported anymore and are not compatible.
835 * Removed nickname from Channel Payload as the latest draft removed
836 it. The client must resolve the nickname from the NAMES command
837 reply received when it joined the channel.
839 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
841 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
843 * Fixed some errors in protocol specification drafts.
845 * Created lib/silccore/silcnotify.c to implement Notify Payload
846 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
847 generic payloads described by protocol specifications. The file
848 includes implementations for ID Payload and Argument Payload.
850 * Changed Command Payload implementation to use the new Argument
851 Payload. Changed command_xxxx_payload to command_payload_xxxx
852 to comply with SILC coding conventions.
854 * Added suppport for Argument Payload handling in Notify Payload
855 implementation as protocol requires it. Added the new support
856 into server and client lib as well.
858 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Added support for multiple nicknames on same channel. [n] is
861 added locally to the nickname if there are more than one same
862 nicknames on the channel.
864 * Server now sends all nicknames that matched WHOIS request.
865 Client also shows the list received from server.
867 * Added TOPIC command to client side. User can now set and show
868 current topic on channel.
870 * Added MOTD command to client and server. Also, server sends the
871 motd when client connects to the server.
873 * Changed version strings to comply ISO 8601.
875 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
877 * Fixed protocol error handling in client library. It should now
878 cope even if the SKE fails for some reason.
880 * Made new protocol specification drafts for submitting to IETF.
882 * Implemented TOPIC command to server in silcd/command.c.
884 * Added two new notify types into lib/silccore/silcnotify.h:
885 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
886 notify nickname change and topic setting/change on a channel.
888 * API change of command_reply operation in client library. The
889 application gets now the status type received from server as well.
891 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Removed the function just added to lib/silcutil/silcschedule.[ch].
895 * Cras fixed and optimized the packet handling even further and
896 it should work now. Minor change to the prototype of function
897 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
899 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
901 * Added new function into lib/silcutil/silcschedule.[ch]:
902 silc_schedule_with_fd to select() a specified fd. The function
903 returns after timeout expires or data arrives or goes. The
904 function is used by packet routines to wait that all data is
905 received from network.
907 * Fixed data reading from network in lib/silccore/silcpacket.c.
908 The code now assures that all data is read from the fd and then
909 continues packet processing. This was a bug fix since the code
910 used to drop some data in some circumstances.
912 * Added new function into lib/silcclient/client.[ch]:
913 silc_client_start_key_exchange to start key exchange after
914 connection has been established to server. The code internally
915 now uses this funtion but its main purpose was to provide it
916 for applications that perform their own connecting. After
917 application has created a connection it merely calls this
918 function to start the key exchange between client and server.
919 The library takes care of everything else after that.
921 Updated also lib/silcclient/README to explain the usage of
924 * Do not send to application information that connection has
925 been established. Application gets notified it by connect
928 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Applied cras's patch to add silc_schedule_one function. The
931 function runs scheduler once and returns.
933 * Fixed the scheduler after cras messed it up. The timeout
934 handling works now as it's supposed to work.
936 * Added into lib/silccore/ silcnotify.h to include notify
937 message types support. Changed silc_server_send_notify*
938 functions, in server.[ch], to support those new notify types.
939 Added the support for the notify types into client library,
940 as well. Added new notify client operation into ops.h in
943 * Changed silc_server_packet_send_to_channel to send normal
944 packets instead of just channel message packets. The function
945 is now used to send the notify packets to channels. It is not
946 used to send channel message packets anymore, as server never
949 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
950 va_arg()s as it seems to require it nowadays. I guess, if SILC
951 is compiled with older va_arg() the new code should work anyway.
953 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Splitted core library. Core library (lib/silccore) includes
956 now only SILC protocol specific core (and common) components.
957 Created new utility library (lib/silcutil) that includes more
958 generic purpose stuff. The stuff for util library was taken
959 from the old core library. This was minor and easy split.
961 * Created SILC Client Library (lib/silcclient) that includes
962 implementation of the SILC client without user interface. This
963 was major move from silc/ directory. The code has been changed
964 so that it is transparent towards the user interface. The
965 silc/ directory includes now the same user interface as before
966 and it uses the new client library. Read lib/silcclient/README.
967 Basicly, the client library performs everything else related
968 to SILC except user interface handling. Also, configuration
969 files are considered to be part of user interface and library
970 does not handle them.
972 This change also changed a lot of structures, function naming etc.
973 Most important change was that SilcClientWindow object was
974 renamed to SilcClientConnection in the client library. Created
975 also new file lib/silcclient/ops.h. Also added new files
976 silc/local_command.[ch] and silc/client_ops.[ch].
978 All these changes were made to make it easier for user interface
979 designers to create what ever user interface for the SILC client
982 It is also expected that the server will be moved to lib
983 directory as well and SILC Server Library will be created;
984 sometimes in the future.
986 * Removed Local commands from lib/silccore/silccommand.h as
987 they are application specific and new client library does not
988 handle any of those anymore.
990 * Several functions moved to lib/silcutil/silcutilc.[ch] from
991 old client implementation in silc/.
993 * Added support for callback functions in SILC_LOG_* macros.
994 Application can now set its own callbacks that will be called
995 instead of using the default functions that will always print
996 the debug messages to stderr (or stdout). Also, debugging can
997 now be disabled by setting silc_debug to FALSE and re-enabled by
998 setting it to TRUE. Note, that logging will still work even
999 if debugging is disabled.
1001 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1002 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1003 silc_log_reset_debug_callbacks.
1005 * To enable debugging in silc client one must give now -d
1006 option on command line.
1008 * Changed silc_schedule_init to automatically allocate task queues
1009 if they are not allocated before calling it.
1011 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1013 * Added GMP 3.1 into math library.
1015 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1017 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1018 a channel in SILC network. The packet is used by servers and
1019 routers to notify other routers that user has left a channel.
1020 This little feature was missing until now. Added the feature
1021 to protocol specification as well.
1023 Added functions: silc_server_send_remove_channel_user and
1024 silc_server_remove_channel_user into server.[ch].
1026 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1027 lib/silccore/silcpacket.h. However, they are not implemented
1030 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Fixed joining to a channel and sending channel messages
1033 between server and router. The channel message sending should
1034 now work inside a cell.
1036 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Fixed the private message sending between server and router.
1039 The private message sending should now work inside a cell.
1041 * Added silc_server_replace_id into server.[ch] to replace
1042 existing ID in the SILC network.
1044 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1045 and silc_idlist_replace_server_id into idlist.[ch] in server.
1047 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1049 * Fixed the server to server connections. Server can again now
1050 connect to router. Router to router connections probably does
1053 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Added dynamic protocol registering support. Now protocols can
1056 registered and unregistered on the fly. Patch by cras.
1058 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1060 * Added lib/contrib directory to hold routines that some platforms
1061 don't have but are needed by SILC.
1063 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1064 into lin/contrib to provide getopt() and getopt_long() for
1065 those who don't have it.
1067 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Added AWAY command to client. When away message is set and
1070 client receives a private message packet the client automatically
1071 replies to the sender with the away message.
1073 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1074 bug seemed to be the cause of recent problems when compiling
1077 * Added version detection support to SKE protocol specification
1078 and added the new changes to the SKE implementation as well.
1079 There were other minor changes in the SKE protocol as well.
1081 Many changes in lib/silcske/silcske.[ch] and in
1082 lib/silcske/payload.[ch].
1084 * Added ^U functionality, clear input line. Patch from cras.
1086 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Mainly small bugfixes on core library. Fixed some debugging
1089 logging and buffer overflow in silclog.c.
1091 * Updated config.sub and config.guess on the distribution tree.
1093 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added command lagging support in server. Client may execute
1096 commands now only once in two seconds.
1098 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Optimized packet reception. MAC computation and checking is now
1101 also more optimized. A lot previously duplicated code is now
1102 used as generic by both client and server.
1104 * Fixed key pair generation in clientutil.c
1106 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Added into lib/silccore/silcbufutil.[ch] new function;
1109 silc_buffer_realloc.
1111 * Moved generic packet sending/encryption functions to
1112 lib/silccore/silcpacket.[ch] from client and server. Some
1113 rewriting of the functions.
1115 * Moved all generic packet reception/decryption functions to
1116 lib/silccore/silcpacket.[ch] from client and server. The
1117 packet processing is now much cleaner in both client and server.
1118 These were major changes in both client and server.
1120 * Created many common functions in server to do packet sending.
1121 Previously code were duplicated a lot, this has been removed
1124 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1126 * Rewrote major parts of the ID cache system. Don't know
1127 whether it is better now or not but at least the API is more
1130 * Major rewrite on ID cache stuff on client because of the ID
1131 cache API changes. Added idlist.c to client.
1133 * Also major rewrite on ID cache stuff on server as well.
1134 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1135 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1136 in hand, instead they are all put into the ID cache system now.
1137 All server_idlist_* routines uses ID cache now instead of
1138 traversing its own lists (those lists does not exist anymore).
1139 SilcIDList though still exists. Also, SilcXXXEntry's are
1142 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Finally made the SKE implementation compliant to the protocol
1145 specification. All mp integers are now binary encoded as
1146 opposed being HEX encoded.
1148 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1151 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1152 functions: silc_[encode/decode]_pem. Also added function
1153 silc_encode_pem_file to PEM encode with newlines ('\n') for
1156 * SILC public keys are now encoded either PEM or binary. Same
1157 option is for private keys as well. By default private keys
1158 are binary encoded and public keys PEM encoded. Silly HEX
1159 encoding were removed.
1161 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1162 function to create fingerprints.
1164 * Fixed a bug in SHA1; does not change the original data anymore.
1166 * Partly implemented INFO command on client and server side.
1167 Fixed CLEAR command. Changes to SERVER command; show current
1168 server(s) when giving command without arguments. Added
1169 VERSION command to client.
1171 * Added check to server that unregistered connections cannot
1172 execute commands (unless it is specificly allowed).

1176 * Fixed screen refresh.
1178 * Fixed channel joining bug from client. On some circumstances
1179 client tried to join to a channel it had already joined.
1181 * Added public key verification process into client's protocol.c.
1182 The client now verifies the public key from user and saves
1183 it into ~./silc/serverkeys/ directory.
1185 Added into: clientutil.[ch]: silc_client_verify_server_key.
1187 * Changed SKE protocol's silc_ske_initiator_finish function
1188 to accept callback function that verifies the received public
1189 key. Removed old silc_ske_verify_public_key function.
1191 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1194 silc_pkcs_private_key[_data]_set.
1196 * Made the password and public authentication more cleaner in
1197 server's protocol.c.
1199 * Removed historic and obsolete protocol `channel_auth' from
1200 both client and server.
1202 * Removed wrong way of sending command status messages from
1203 server to client in server's command.c. The old way violated
1204 protocol specification.
1206 Changes to silccore/silccommand.[ch]: removed
1207 silc_command_encode_status_payload -> not needed anymore,
1208 changed silc_command_encode_payload_va to accept extra
1209 argument on variable argument list. The argument type must
1210 now be provided to the function. Also, added new function:
1211 silc_command_encode_reply_payload_va which is same as
1212 normal command_encode_payload_va except command status type
1213 is provided as extra argument.
1215 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1217 * Added ~./silc directory handling. The directory includes the
1218 public and private keys for the client.
1220 Added silc_client_check_silc_dir, silc_client_create_identifier
1221 and silc_client_load_keys.
1223 * Implemented SILC protocol compliant public key. Added public
1224 and private key saving to and loading from files.
1226 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1227 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1228 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1229 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1230 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1232 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1233 silc_pkcs_load_[public/private]_key.
1235 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Added silc_server_get_route (route.[ch]) to get connection
1238 data for the fastest route for given ID.
1240 * Implemented INVITE command on client and server. The command
1241 were re-defined in the SILC Protocol Specification and the
1242 implementation now complies with the specification.
1244 * Implemented PING command on client and server.
1246 * Implemented NAMES command on client and server. The server side
1247 supports currently only normal server not router server yet.
1248 Some changes to NAMES definition in SILC protocol specification.
1250 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Implemented LEAVE command on client and server.
1254 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1255 again. This change was made to the protocol as well. Server
1256 should not violate the protocol specification anymore.
1258 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1261 was tested. SOCKS4 was not but should work anyway.
