3 * Implemented the sending of the SERVER_SIGNOFF notify in the
4 server. Affected file is silcd/server.c.
6 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
7 Added also silc_notify_payload_encode_args into the
8 lib/silccore/silcnotify.[ch].
10 * Implemented ther SERVER_SIGNOFF notify handling in the server.
11 Affected file silcd/packet_receive.c.
13 * Implemented the SERVER_SIGNOFF notify handling in the client
14 library. Affected file lib/silcclient/client_notify.c. Also,
15 implemnted the printing of the SERVER_SIGNOFF info to the
16 application. Affected file silc/client_ops.c.
18 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
19 if the deleting was successful. Affected file silcd/idlist.[ch].
21 * Added support for public key authentication in the connection
22 authentication protocol in the client library. Affected file
23 lib/silcclient/protocol.c.
25 * Changed the server's silc_idlist_get_clients_by_* interface
26 to support already allocated array so that new entries may be
27 added to pre-allocated array. Affected file silcd/idlist.[ch].
28 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
31 * All command reply functions in the server now calls the
32 pending command callback even if error occured. This way the
33 error will be delivered to the client as well. Affected files
34 silcd/command.c and silcd/command_reply.c.
36 * Fixed INFO command to return local server's info if no server
37 was provided. Affected file lib/silcclient/command.c.
39 * Removed RESTART command for good. Updated the code and the
42 * Rewrote parts of the task system. It is a bit simpler now.
43 Removed unsued task priorities. The affected files are
44 lib/silcutil/silctask.[ch].
46 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Moved the USERS printing from the library to the application.
49 Affected files lib/silcclient/command.c and silc/client_ops.c.
51 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Added channel key re-key support. The re-key is perfomed
56 only by the router and is done once in an hour. Added `rekey'
57 field to the SilcChannelEntry in the server. Affected files
58 silcd/server.c and silcd/idlist.h.
60 * Added silc_task_unregister_by_context into the file
61 lib/silcutil/silctask.[ch].
63 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Added SILC_UMODE_GONE mode to indicate when the client is not
66 present in the SILC network. Added also support to the local
67 command AWAY that will set this mode. Added support of showing
68 "xxx is gone" in WHOIS command. The USERS command shows the
71 * Fixed setting server and router operator privileges in the
72 server's UMODE command. Affected file silcd/command.c.
74 * Merged the SKE KE1 and KE2 payloads into one payload. The
75 new KE payload is equivalent to the old KE2 payload.
77 Cleaned up the SKE Start Payload parsing. It now uses the
78 simple buffer unformatting to do the parsing. A lot faster
81 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
82 to the SKE that is used to indicate whether both of the SKE
83 parties should perform authentication. By default only the
84 responder performs authentication. By setting this flag also
85 the initiator must do authentication. By default it is unset
86 since in normal SKE case, client to server connection, only
87 the responder should do authentication. When doing SKE between
88 two clients both should perform authentication. Updated the
89 code and the protocol specs.
91 * A little fix to IDENTIFY command in the server. Search the
92 client first by hash not nickname. Affected file is
95 * Fixed the silc_client_close_connection to support closing
96 the client to client connections wihtout deleting too much
97 data. Affected file lib/silcclient/client.c.
99 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
100 are received if protocol used to be active but is not anymore
101 the application would crash due to NULL pointer dereference.
102 Affected files silcd/server.c and lib/silcclient/client.c.
104 * Added `hash' field to the SilcClientConnection to include
105 the hash function negotiated in the SKE protocol.
107 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
108 to set the channel founder authentication data. A client can
109 claim the founder rights later by providing the authentication
110 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
111 This way the channel founder can regain the channel founder
112 privileges even it is left the channel. This works only on
113 local server and the client must be connected to the same
114 server to be able to regain the founder rights. Updated the
115 protocol specs accordingly.
117 Added support to the CMODE command in the client to set the
118 founder auth data. Read the README to see how to set it.
120 Added support to the CUMODE command to claim the founder
121 rights. Read the README to see how to do it.
123 Added support for the founder authentication to the Channel
124 Entry in the server. Affected file silcd/idlist.h.
126 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
127 server's CMODE command. Affected file silcd/command.c.
129 * Added the following new functions into lib/silccore/silcauth.[ch]:
130 silc_auth_get_method and silc_auth_get_data.
132 * The server now saves the remote hosts public key to the
133 SilcIDListData pointer. Affected file silcd/protocol.c.
135 * The normal server now does not remove the channel entry from
136 the cache if the founder authentication data is set. It used
137 to remove it if the founder was the last one on the channel on
138 the server and left the channel. The auth data is saved and
139 if the channel is re-joined later the old entry is used with
140 the old auth data. Affected files silcd/command_reply.c and
143 * Removed the `pkcs' field from the SilcIDListData structure
144 in the server; it is not used. Affected file silcd/idlist.h.
146 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed packet processing on slow links. Partial packets were
149 never re-processed because the incoming data buffer was cleared
150 by the application. Application must not directly clear the
151 sock->inbuf, the packet processing routines handle it. Fixed
152 this in client library and in server.
154 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Fixed the WHOIS and IDENTIFY send reply function to really
157 check whether to send list or just one entry. Affected file
160 * Cleaned up the LEAVE command's channel key distribution. The
161 affected file silcd/command.c.
163 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
164 can enforce the channel mode as well. In that case the ID
165 includes the ID of the server. The code now enforces the
166 mode change if the router have different mode than the server.
168 * The notify client operation with CMODE_CHANGE notify can now
169 return NULL client_entry pointer if the CMODE was not changed
170 by client. Application must check for this.
172 * Added <Server ID> argument to INFO command to support server
173 info fetching by Server ID.
175 * Added silc_server_announce_get_channel_users to get assembled
176 packets of channel users of the specified channel. Affected
177 file silcd/server.[ch].
179 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
180 was freed underneath the ID Cache.
182 * Re-announce clients when the server received CHANNEL_CHANGE
183 notify from the router. Affected file silcd/packet_send.c.
185 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
187 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
188 crashed since it did not handle the fact that there is no cipher
189 called "3" and didn't check the error condition. Now fixed.
191 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
192 flag. It can be used to send message requests.
194 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Implemented the RESTART command in the client.
198 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
199 notice type messages. Added notice printing to the user
202 * The channel keys are not re-generated if the channel's mode
203 is PRIVKEY, ie private key on the channel exists. Affected
204 files silcd/server.c and silcd/command.c.
206 * Fixed a little bug in channel message delivery when channel
207 private keys are set in the server. Affected file is
210 * Changed the setting on channel->on_channel = TRUE from the
211 silc_client_save_channel_key to the JOIN command reply. The
212 key payload is not received if the private channel key is set.
213 Affected file lib/silcclient/command_reply.c and the
214 lib/silcclient/client_channel.c.
216 * When the CMODE_CHANGE notify is sent and the channel private
217 key mode is removed the channel key must be re-generated in
218 other cells as well. Added this support for the router in the
219 silcd/packet_receive.c.
221 * Added new local command NOTICE to send notice message on
222 channel. Affected file silc/local_command.[ch].
224 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Added new local command ME to the client. It is used to send
227 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
228 some action. Affected file silc/local_command.[ch].
230 * Changed channel_message and private_message client operations
231 to deliver the message flags to the application. Added also
232 the `flags' arguments to the silc_client_send_channel_message
233 and silc_client_send_private_message functions. Affected file
236 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Redefined the Private Message Payload to support private message
239 keys and to support the new private message flags. Updated
240 the protocol specs. Flags makes it possible to have for example
243 * Added new type SilcPrivateMessagePayload and defined an API
244 for it in the lib/silcclient/silcprivate.[ch].
246 * Tested private message private keys successfully. Tested the
247 private message key set, unset and list commands with the new
250 * Redefined the Channel Message Payload to include the channel
251 message flags (equal with private message flags) to support
252 for example CTCP style messages.
254 * Defined some of the message (for channel and private message)
255 flags. Updated the protocol specs and added the flags to the
256 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
258 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Added SilcKeyAgreementStatus type to the key agreement routines
261 to indicate the current status and error if one occured.
262 The status types are defined in the lib/silcclient/silcapi.h.
264 * Added new local command KEY that is used to set and unset private
265 keys for channels, set and unset private keys for private messages
266 with remote clients and to send key agreement requests and
267 negotiate the key agreement protocol with remote client. The
268 key agreement is supported only to negotiate private message keys,
269 it currently cannot be used to negotiate private keys for channels,
270 as it is not convenient for that purpose.
272 * Fixed a minor pending callback setting bug in the function
273 silc_client_get_client_by_id_resolve, now the function works.
274 Affected file lib/silcclient/idlist.c.
276 * Added function silc_net_get_local_port to get local bound
277 port by socket. Added to lib/silcutil/silcnet.[ch].
279 * Added `sockets' and `sockets_count' fields to the SilcClient
280 object. They hold the sockets of the listenning sockets in
281 the client. Listenning sockets may be for example the key
282 agreement server. Affected file lib/silcclient/client.[ch].
283 Added functions the silc_client_add_socket and the
284 silc_client_del_socket. They are exported to the application
287 * Added ~./silc/clientkeys to support other client's public keys.
289 * Renamed verify_server_key client operation to verify_public_key
290 and added one argument to indicate the type of the connection
291 (server, client etc.).
293 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
295 * Added silc_server_connection_auth_request to handle the
296 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
297 silcd/packet_receive.[ch].
299 * Added silc_server_send_connection_auth_request into the
300 silcd/packet_send.c to send the connection auth request packet.
302 * Cleaned up the silcd/protocol.c a bit and fixed some memory
305 * Fixed the public key authentication in responder side in the
306 server. The `auth_data' pointer includes the SilcPublicKey
307 not the path to the public key. Affected file silcd/protocol.c.
309 * Implemented the public key authentication in the initiator side
310 in the server. Affected file silcd/protocol.c.
312 * Removed the [RedirectClient] config section from the server
313 configuration. Is not needed and I don't want to implement it.
315 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * Cleaned up the CMODE command in the server. It now works
318 correctly and supports all the modes defined in the protocol.
319 Affected file is silcd/command.c.
321 * Added `hmac_name' field to the SilcChannelEntry in the server
322 to hold the default HMAC of the channel. It can be set when
323 creating the channel (with JOIN command). Affected files
326 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
327 type to indicate the change of the current cipher and hmac
328 on the channel. Client can safely ignore the <cipher> argument
329 (if it chooses to do so) since the CHANNEL_KEY packet will
330 force the channel key change anyway. The <hmac> argument is
331 important since the client is responsible of setting the new
332 HMAC and the hmac key into use.
334 * Fixed the CMODE command in the client library as well.
336 * Tested CMODE command in router environment successfully.
338 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
340 * Show the version of the remote client (or server) when connecting
341 to the server. It is logged to the log file. Affected file
344 * Fixed the KILLED notify handling in the client library. The
345 client must be removed from all channels when receiving the
348 Also, do not remove the client entry when giving the KILL
349 command but when the KILLED notify is received.
351 * Removed silc_idlist_find_client_by_nickname from the server.
352 Not needed anymore. Affected files silcd/idlist.[ch].
354 * Implemented the CHANNEL_CHANGE notify type handling to the
355 server. Affected file silcd/server.c.
359 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

374 client entry by ID from all ID lists and then resolve it
375 (using WHOIS) if it cannot be found. Affected file is
378 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
380 * Implemented the BAN command to the client library.
382 * The JOIN command in the server now checks the invite list
385 * Changed the silc_command_reply_payload_encode_va and the
386 silc_command_payload_encode_va to support that if argument is
387 NULL it ignores and checks the next argument. Affected file
388 lib/silccore/silccommand.c.
390 * Added silc_server_send_notify_ban to send the BAN notify
391 type between routers.
393 * Chaned the silc_notify_payload_encode to support that if
394 argument is NULL it ignores and checks the next argument.
395 Affected file lib/silccore/silcnotify.c.
397 * Tested ban lists in router environment successfully.
399 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
401 * Implemented BAN command to the server, in silcd/command.[ch].
403 * Removed the BAN and INVITE_LIST modes from the CMODE command
406 * Added function silc_string_match to regex match two strings.
407 Affected files lib/silcutil/silcutil.[ch].

412 the new ban and invite lists.
414 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Redefined the INVITE command. The same command can be used to
417 invite individuals to the channel but also to manage the invite
418 list of the channel (to add to and remove from the invite list).
419 Updated the protocol specs.
421 * Added new command SILC_COMMAND_BAN that can be used to manage
422 the ban list of the channel. Updated the protocol specs.
424 * Removed the channel modes: the SILC_CMODE_BAN and the
425 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
426 in the CMODE command. The equivalent features are now available
427 using INVITE and BAN commands. Updated the protocol specs.
429 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
430 in the network about change in the current ban list. The notify
431 type is not used by the client.
433 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
434 support the invite lists.
436 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * Added new function silc_string_regexify that converts string
439 including wildcard characters into regex string that can
440 be used by the GNU regex library. Added into the file
441 lib/silcutil/silcutil.[ch].
443 Added silc_string_regex_combine to combine to regex strings
444 into one so that they can be used as one regex string by
445 the GNU regex library. Added into the file
446 lib/silcutil/silcutil.[ch].
448 Added silc_string_regex_match to match two strings. It returns
449 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].

477 With private channels the user count is not shown.
479 * Updated TODO and README.
481 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
483 * The client entry's data.registered must be TRUE even with
484 global client entry on global client list. The data.registered
485 is used to check whether the client is anymore in the network,
486 for example with WHOWAS command so it must be valid.
488 * Fixed the WHOWAS command in the server. It now actually works
489 in router environment. Added function into silcd/command_reply.c
490 silc_server_command_reply_whowas_save.
492 * Added silc_idlist_purge function to the silcd/idlist.c
493 to periodically purge the ID Cache.

502 * Fixed various bugs in WHOIS and IDENTIFY command handling as
503 they were buggy because of the WHOWAS information.
505 * Fixed local command MSG to handle the async resolving of
506 the remote client properly. It used to fail the first MSG.
507 Affected file silc/local_command.c.
509 * Added `data_len' field to SilcIDCache context.
511 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
513 * Update TODO. Todo in commands in the server.

526 Payload. The New Channel Payload is now the generic Channel
529 * Added new argument `mode' to the silc_server_send_new_channel
530 as it is required in the Channel Payload now.
532 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
533 and created a new and real SilChannelPayload to represent the
534 new generic Channel Payload. Implemented the encode/decode
535 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].

542 in server and in the client.
544 Implemented the channel list displaying on the user interface
545 as well. Affected file silc/client_ops.c.
547 * Added silc_channel_payload_parse_list to parse list of Channel
548 Payloads. It returns SilcDList list of SilcChannelPayloads.
549 Client for example can use this function to parse the list of
550 channels it receives in the WHOIS command reply. The caller
551 must free the list by calling silc_channel_payload_list_free.
552 Affected files lib/silccore/silcchannel.[ch].
554 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Added one new argument <user mode> to the WHOIS command reply
557 to return the mode of the user in SILC. Updated the protocol

573 unknown command. Affected file silcd/command.c.
575 * All server commands now handle the command identifier the right
576 way when sending the command reply to the client. The client can
577 use to identify the command replies with the identifier.
579 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Added silc_server_get_client_route to resolve the route to
582 the client indicated by the client ID. Affected file is
585 * Added silc_server_relay_packet as general function to relay
586 packet to arbitrary destination. This deprecates functions
587 like _send_private_message_key, _relay_notify etc. Affected
588 file is silcd/packet_send.[ch].
590 Removed silc_server_send_key_agreement,
591 silc_server_send_private_message_key and
592 silc_server_packet_relay_notify functions from the file
593 silcd/packet_send.[ch].

598 server. Affected file silcd/packet_receive.[ch].
600 * Implemented the KILL command to the client. Implemented the
601 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
602 Affected files lib/silcclient/command[_reply].c and
603 lib/silcclient/client_notify.c. Implemented the KILL notify
604 printing in the user inteface.
606 * Fixed a lot silc_parse_nick memory leaks from the client
607 library in the file lib/silcclient/command.c.
609 * Changed the silc_server_send_notify_on_channels's `sender'
610 argument from SilcSocketConnection to SilcClientEntry to
611 check the sender as entry and not as connection object and not
612 to send to the client provided as argument. The affected file
613 is silcd/packet_send.[ch].
615 * The notify packets that are destined directly to the client used
616 to not to be processed by the server. Now changed that and the
617 server processes all notify packets. After relaying the packet
618 to the client the notify packet is processed in the server.
620 * The silc_server_free_client_data now checks whether there is
621 pending outgoing traffic for the client and purges the data to
622 the network before removing the client entry.
624 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
627 an client is killed from the SILC Network. Updated the protocol
630 Added new function silc_server_send_notify_killed to the
631 silcd/packet_send.[ch].
633 * Added function silc_server_packet_relay_notify to relay notify
634 packets that are destined directly to a client. In this case
635 the server does not process the notify packets but merely relays
636 it to the client. Affected file silcd/packet_send.[ch].
638 Added also silc_server_packet_process_relay_notify to check
639 whereto relay the notify. Affected file is
640 silcd/packet_receive.[ch].
642 * Implemented the KILL command to the server.
646 * Added the backup schema desgined last fall to the protocol
647 specs for everyone to see. The specification is in the
648 *-spec-xx.txt draft and the packet type definitions for the
649 backup routers is in *-pp-xx.txt draft. Thusly, added also
650 new packet type SILC_PACKET_CELL_ROUTERS.
652 * A big security problem in the implementation discovered. The
653 signoff of an client did not cause new channel key generation
654 which it of course should've done. The channel keys must be
655 always re-generated when client leaves (or signoffs) the channel.
656 The silc_server_remove_from_channels funtion now handles
657 the channel key re-generation.
659 * Added `sender' argument to the silc_server_send_notify_on_channels
660 to not to send the client provided as argument. Affected file
661 silcd/packet_send.[ch].
663 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Implemented OPER and SILCOPER commands into the server and
668 * Added silc_auth_verify and silc_auth_verify_data to verify
669 the authentication directly from the authentication payload.
670 It supports verifying both passphrase and public key based
671 authentication. Affected file lib/silccore/silcauth.[ch].
673 * Added `hash' field to the SilcIDListData structure. It is the
674 hash negotiated in the SKE protocol. Affected file is
677 * Slight redesigning of the SilcAuthPayload handling routines.
678 Do not send SilcPKCS but SilcPublicKey as argument.
680 * Implemented the public key authentication support to the
681 serverconfig. The public key is loaded from the provided path
682 and saved as authentication data to void * pointer. Thus,
683 changed the unsigned char *auth_data to void *auth_data;
685 * Fixed SHUTDOWN command to send the reply before the server
686 is shutdown. :) Affected file silcd/command.c.
688 * Fixed fatal bug in CONNECT command. The hostname was invalid
689 memory and server crashed. Affected file silcd/command.c.
691 * Fixed fatal bug in CLOSE command. The server_entry became
692 invalid but was referenced later in the command. Affected file
695 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
697 * Fixed fatal bug in failure packet handling. Server ignored
698 the failure and thus crashed when it came.
702 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
705 that the command may be executed only once in (about) 2 seconds.
706 The old SILC_CF_LAG flag is same but allows command bursts up
707 to five before limiting.
709 Added the support for CF_LAG and CF_LAG_STRICT flags to the
710 server code. Various commands now includes the CF_LAG_STRICT
711 flag to disallow any kind of miss-use of the command.
713 * Fixed the silc_buffer_unformat to not to allocate any data
714 if the length of the data is zero. It used to allocate the
715 length + 1. Affected file lib/silcutil/silcbuffmt.c.
717 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
719 * Changed the format of AdminConnection configuration section
720 in the server. Added username of the admin to the format.
721 Affected files silcd/serverconfig.[ch].
723 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
724 to return admin configuration data by host, username and/or
727 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
729 * Implemented WHOWAS command to the server. Added the functions:
731 silc_server_command_whowas_parse,
732 silc_server_command_whowas_send_reply,
733 silc_server_command_whowas_from_client and
734 silc_server_command_whowas_from_server
736 * Added <Client ID> argument to the WHOWAS command reply. Updated
737 the protocol specs accordingly.
739 * Implemented WHOWAS command and command_reply to the client
742 Implemented the WHOWAS printing on the user interface.
744 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Added new argument to the WHOWAS command reply, the real name.
747 It is an optional argument. Updated the protocol specs.
749 * Added SilcIDCacheDestructor callback that is registered when
750 the SilcIDCache is allocated. The callback is called when
751 an cache entry in the ID Cache expires, or is purged from the
752 cache. Added into lib/silccore/idcache.[ch].
754 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
755 to destruct the client entries when the cache entry expires.
756 Other ID Cache's in server and in the client library ignores
759 * If the ID Cache entry's `expire' field is zero then the entry
760 never expires. Added boolean `expire' argument to the
761 silc_idcache_add function in the lib/silccore/idcache.[ch].
762 If it is TRUE the default expiry value is used.
764 * Added silc_server_free_client_data_timeout that is registered
765 when client disconnects. By default for 5 minutes we preserve
766 the client entry for history - for WHOWAS command.
768 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Added support to the server to enforce that commands are not
771 executed more than once in 2 seconds. If server receives
772 commands from client more frequently, timeout is registered
773 to process the commands. Affected file silcd/command.c.
774 Added new function silc_server_command_process_timeout.
776 * Changed NICK_NOTIFY handling in client library to check that
777 if the client's nickname was changed, so there is no need to
778 resolve anything from the server.
780 * Removed error printing from the WHOIS and IDENTIFY commands.
781 If error occurs then it is ignored silently in the client library.
782 The application, however, may map the received error to
783 human readable error string. The application currently maps
784 the NO_SUCH_NICKNAME error to string.
786 * Made the command status message public to the application. Moved
787 them from lib/silcclient/command_reply.c to
788 lib/silcclient/command_reply.h. The application can map the
789 received command status to the string with the
790 silc_client_command_status_message function.
792 * Added check to the server to check that client's ID is same
793 as the Source ID in the packet the client sent. They must
796 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Added dist-bzip hook to the Makefile.am to make bzip2
799 compressed distributions.
801 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
803 * Server now enforces the maximum length for the nickname and
804 the channel as protocol specification dictates. 128 bytes for
805 nickname and 256 bytes for channel name.
807 * Moved the WHOIS printing to the application. The client libary
808 does not print out the WHOIS information anymore, the application
809 must do it. Renamed silc_client_command_reply_whois_print to
810 the silc_client_command_reply_whois_save.
812 The client's idle time is also sent to the application now, and
813 the idle is shown on screen.
815 * Added silc_client_command_reply_identify_save to save the
816 received IDENTIFY entries.
818 * Do not check for channel private keys in message sending and
819 reception if the channel does not have the PRIVKEY mode set.
820 Affected file lib/silclient/client_channel.c.
822 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
825 just surfaced after chaning the JOIN procedure.
827 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Added silc_client_get_clients_by_list to get client entries
830 from Client ID list, that is returned for example by JOIN
831 and USERS command replies. The application should use this
832 function for example when JOIN command reply is received to
833 resolve the clients already on the channel (library does not
834 do that anymore as USERS command reply is not used in the JOIN
835 procedure anymore). Affected files lib/silcclient/silcapi.h and
836 lib/silcclient/idlist.c.
838 * JOIN command reply and USERS command reply returns now SilcBuffer
839 pointers instead of unsigned char pointers when returning
840 the client list and mode list.
842 * Added <Client ID> argument to the JOIN command reply, mainly
843 for the server to identify for which client the command was
844 originally sent. Updated protocol specs accordingly.
846 * Added SilcDlist private_key pointer to the SilcChannelEntry
847 in the client to support the channel private keys. Affected
848 file is lib/silcclient/idlist.h.
850 * Added SilcChannelPrivateKey argument to the function
851 silc_client_send_channel_message so that application can choose
852 to use specific private ke if it wants to. If it is not provided,
853 the normal channel key is used, unless private keys are set.
854 In this case the first (key that was added first) is used
855 as the encryption key.
857 * Implemented the support for channel private key handling.
858 Implemented the following functions:
860 silc_client_add_channel_private_key,
861 silc_client_del_channel_private_keys,
862 silc_client_del_channel_private_key,
863 silc_client_list_channel_private_keys and
864 silc_client_free_channel_private_keys
866 Affected file lib/silcclient/client_channel.c.
868 * Added the support for the private keys in the channel message
869 sending and encryption and in the message reception and
870 decryption. Affected funtions are
871 silc_client_send_channel_message and silc_client_channel_message.
873 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Added SKE's key verify callback to the client library's
876 KE protocol context. Affected files lib/silcclient/protocol.[ch].
878 * Removed the statement that server (or router) must send USERS
879 command reply when joining to the channel so that the client
880 knows who are on the channel. Instead, the client list and
881 client's mode list is now sent in the JOIN command reply to the
882 client who joined channel. This is better solution.
884 * Added function silc_server_get_users_on_channel and function
885 silc_server_save_users_on_channel to the silcd/server.[ch].
887 * Removed function silc_server_command_send_users from the
890 * Do not show topic on the client library anymore. The topic is
891 sent in the command reply notify to the application and the
892 application must show the topic now.
894 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Added client searching by nickname hash into the IDENTIFY and
897 WHOIS commands in the server as they were clearly missing from
898 them. Affected file is silcd/command.c.
900 * Fixed a bug in private message receiving in the client library.
901 The remote ID was freed and it wasn't supposed, now it is
904 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
906 * Minor fix to the channel payload; allocate the data area, as it
907 needs to be of specific length.
909 * If the key agreement port is zero then the operating
910 system will define the bound port. Affected files are
911 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
913 * Added new function silc_channel_payload_decrypt into the file
914 lib/silccore/silcchannel.[ch].
916 * Moved the channel message etc, check from silc_packet_decrypt
917 to applications. The library calls now a generic
918 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
919 when the packet is either normal or special. This was done to
920 allow more wide range of checking that was not allowed when
921 the code was in library. Now applications can do virtually any
922 checks to the packet and return to the library the decision how
923 the packet should be processed. Affected files are
924 lib/silccore/silcpacket.[ch].
926 Added silc_server_packet_decrypt_check to the server and
927 silc_client_packet_decrypt_check to the client library.
929 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
930 to send with specified source and destination information.
932 * Channel message delivery between routers was broken after the
933 channel key distribution was fixed earlier. The channel key
934 was used be to distributed to other routers as well which is not
935 allowed by the protocol. Now this is fixed and channel keys
936 really are cell specific and the channel message delivery between
937 routers comply with the protocol specification.
939 * Fixed various commands in server to check also the global list
940 for the channel entry and not just the local list. The affected
941 file silcd/command.c.
943 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Added assert()s to buffer formatting and unformatting routines
946 to assert (if --enable-debug) when error occurs. Affected
947 file: lib/silcutil/silcbuffmt.c.
949 * Changed to auto-reconnect to check whether the remote host is
950 router and register the re-connect timeout if it is. It used
951 to check that whether we are normal server, but router must do
952 auto-reconnect with another router as well. Affected file
955 * Removed the [<key len>] option from CMODE command as the cipher
956 name decides the key length, nowadays. See the defined ciphers
957 from the protocol specification.
959 * Added [<hmac>] option to the CMODE command to define the HMAC
960 for the channel. Added SILC_CMODE_HMAC channel mode.
962 * Added [<hmac>] option for the JOIN command so that user can
963 select which HMAC is used to compute the MACs of the channel
966 * Added Hmac field to the Channel Message Payload. The integrity
967 of plaintext channel messages are now protected by computing
968 MAC of the message and attaching the MAC to the payload. The
969 MAC is encrypted. Now, it is clear that this causes some
970 overhead to the size of the packet but rationale for this is that
971 now the receiver can verify whether the channel message decrypted
972 correctly and also when private keys are set for the channel the
973 receiver can decrypt the packet with several keys and check from
974 the MAC which key decrypted the message correctly.
976 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
977 lib/silccrypt/silccipher.[ch].
979 * Added silc_hash_len to return the digest length into the
980 lib/silcrypt/silchash.[ch].
982 * Rewrote parts of Silc Channel Payload interface in the
983 lib/silccore/silcchannel.[ch]. The encode function now also
984 encrypts the packet and parse function decrypts it.
986 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
988 * Fixed a minor formatting bug in the SKE's key material processing.
989 It actually might have processed the keys wrong way resulting
992 * Redefined the mandatory HMAC algorithms and added new algorithms.
993 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
994 and hmac-md5 truncated to 96 bits. The mandatory is now
995 hmac-sha1-96. Rest are optional (including the one that used
996 to be mandatory). Rationale for this is that the truncated HMAC
997 length is sufficient from security point of view and can actually
998 make the attack against the HMAC harder. Also, the truncated
999 HMAC causes less overhead to the packets. See the RFC2104 for
1002 * Added new [hmac] configuration section. The SKE used to use
1003 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1004 is of course wrong. The official names that must be proposed in
1005 the SKE are the ones defined in the protocol specification
1006 (hmac-sha1-96 for example). The user can configure any hmac
1007 using any hash function configured in the [hash] section. At
1008 least, the mandatory must be configured.
1010 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1012 * Added HMAC list to the SKE proposal list. It has now both
1013 hash algorithm list and HMAC list. This makes the protocol
1014 incompatible with previous versions. The SKE now seems to work
1015 the way it is supposed to work, for the first time actually.
1017 * Defined plain Hash algorithms to the protocol specification.
1020 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1022 * Implemented support for key agreement packets into the server.
1023 Added functions silc_server_key_agreement and
1024 silc_server_send_key_agreement. Other than these functions,
1025 server has nothing to do with this packet.
1027 * Added support for private message key packets into the server.
1028 Added functions silc_server_private_message_key and
1029 silc_server_send_private_message_key.
1033 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1034 called in the protocol's final callback instead in the END
1035 protocol state. This makes a little more sense and in the same
1036 time in client we can use the same protocol routines for normal
1037 key exchange and to key agreement packet handling as well.
1039 * Added to both client's and server's KE protocol context the
1040 SilcSKEKeyMaterial pointer to save the key material. We will
1041 bring the key material to the protocol's final callback by doing
1042 this. The final callback must free the key material.
1044 * Added SKE's packet_send callback into client's KE protocol
1045 context so that the caller can choose what packet sending function
1046 is used. This way we can use different packet sending when
1047 doing normal SKE when doing key agreement packet handling (in
1048 the key agreement packet handling we do not want to encrypt
1051 * Implemented the responder side of the key agreement routines
1052 in the client. The client can now bind to specified port and
1053 accept incoming key negotiation. The key material is passed
1054 to the application after the protocol is over.
1056 * Implemented the processing of incoming Key Agreement packet
1057 in the client. Added function silc_client_key_agreement to
1060 * Implemented the intiator side of the key agreement routines
1061 in the client. The client can now initiate key agreement with
1062 another remote client. The key material is passed to the
1063 application after the protocol is over.
1065 * Created client_keyagr.c to include all the key agreement
1068 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1069 SILC_TASK_CALLBACK except that it is not static.
1071 * Created client_notify.c and moved the Notify packet handling
1072 from the client.[ch] into that file.
1074 * Created client_prvmsg.c and moved all private message and
1075 private message key routines from the client.[ch] into that file.
1077 * Create client_channel.c and moved all channel message and
1078 channel private key routines from the client.[ch] into that file.
1080 * Changed silc_client_get_client_by_id_resolve to resolve with
1081 WHOIS command instead of IDENTIFY command, in the file
1082 lib/silclient/idlist.c.
1084 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * Implemented the SKE's responder side to the Client library.
1088 * When FAILURE is received to the protocol do not trust it
1089 blindly. Register a timeout to wait whether the remote closes
1090 the connection as it should do it, only after that process the
1091 actual failure. This was changed to both client and server.
1093 * Added client_internal.h to include some of the structures
1094 there instead of client.h in lib/silcclient/.
1096 * Added function silc_task_unregister_by_callback to unregister
1097 timeouts by the callback function.
1099 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Some "Incomplete WHOIS info" errors has been appearing on the
1102 log files. Took away the entry->userinfo check from WHOIS
1103 reply sending. The entry->userinfo is now " " if client did not
1104 provide one. I thought this was fixed earlier but something
1105 is wrong still. Let's see if the error still appears.
1107 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Fixed a minor bug in the login when the channel key is
1110 re-generated in the server. It used to generate the key in
1111 wrong order and thus caused problems in the channel traffic.
1113 * Fixed a minor bug in channel key distsribution after
1114 KICK command. The key was not sent to the router even though
1117 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1119 * Added silc_ske_process_key_material_data as generic routine
1120 to process any key material as the SILC protocol dictates. The
1121 function is used by the actual SKE library but can be used by
1122 applications as well. This relates to the private message keys
1123 and the channel private keys since they must be processed the
1124 same way the normal SILC session keys. The protocol dictates
1125 this. Affected files: lib/silcske/silcske.[ch].
1127 Added also silc_ske_free_key_material to free the
1128 SilcSKEKeyMaterial structure.
1130 * Defined silc_cipher_set_key function to set the key for
1131 cipher without using the object's method function. The affected
1132 files: lib/silccrypt/silccipher.[ch].
1134 * Implemented silc silc_client_add_private_message_key,
1135 silc_client_add_private_message_key_ske,
1136 silc_client_del_private_message_key,
1137 silc_client_list_private_message_keys and
1138 silc_client_free_private_message_keys functions in the
1141 Added functions silc_client_send_private_message_key to send
1142 the Private Message Key payload and silc_client_private_message_key
1143 to handle incoming Private Message Key payload.
1145 * Added Cipher field to the Private Message Key payload to set
1146 the cipher to be used. If ignored, the default cipher defined
1147 in the SILC protocol (aes-256-cbc) is used.
1149 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Removed lib/silcclient/ops.h file.
1153 Redefined parts of the SILC Client Library API. Created new
1154 file silcapi.h that deprecates the ops.h file and defines the
1155 published Client Library API. Defined also private message key
1156 API and channel private key API into the file.
1158 This is the file that the application must include from the
1159 SILC Client Library. Other files need not be included by
1160 the application anymore.
1162 * Added new key_agreement client operation callback and also
1163 defined the Key Agreement library API for the application.
1165 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1167 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1168 is used by clients to request key negotiation between another
1169 client in the SILC network. If the negotiation is started it
1170 is performed using the SKE protocol. The result of the
1171 negotiation, the secret key material, can be used for example
1172 as private message key.
1174 Implemented the Key Agreement payload into the files
1175 lib/silccore/silauth.[ch].
1177 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1179 * Redefined ciphers for the SILC protocol. Added some new ciphers
1180 and defined the key lengths for the algorithms. Changed the
1181 code accordingly. The default key length is now 256 bits.
1183 * Fixed SKE key distribution function silc_ske_process_key_material
1184 when the key length is more than 128 bits. The default key
1185 length in SILC is now 256 bits.
1187 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1188 to indicate unsupported algorithm.
1190 * Renamed rijndael.c to aes.c and all functions as well.
1192 * Fixed a long standing channel key setting bug in client library.
1193 Weird that it has never surfaced before.
1195 * Fixed bug in channel deletion. If the entire channel is removed
1196 then it must also delete the references of the channel entry
1197 from the client's channel list as the client's channel entry and
1198 the channel's client entry share same memory.
1200 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Implemented CONNECT and SHUTDOWN commands in the client.
1204 * Implemented CLOSE command to the client.
1206 * Added the function silc_idlist_find_server_by_name into the
1207 files silcd/idlist.[ch].
1209 Added the function silc_idlist_find_server_by_conn into the
1210 files silcd/idlist.[ch].
1212 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * DIE command was renamed to SHUTDOWN. Updated the both code
1217 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1218 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1220 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1223 * Added function silc_server_create_connection function to create
1224 connection to remote router. My server implementation actually
1225 does not allow router to connect to normal server (it expects
1226 that normal server always initiates the connection to the router)
1227 so the CONNECT command is only good for connecting to another
1230 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1233 or some other client was kicked from the channel.
1235 Implemented the handling of the notify type to both client
1238 Implemented silc_server_send_notify_kicked to send the KICKED
1239 notify. It is used to send it to the server's primary router.
1241 * Implemented the KICK command into server and client.
1243 * Added `query' argument to the silc_idlist_get_client function
1244 to indicate whether to query the client from server or not if
1247 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1248 to indicate that the client is not channel founder.
1252 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Removed the rng context from SilcPacketContext structure and
1255 changed that the packet routine uses the Global RNG API.
1257 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Added support for quit message that client can "leave" on the
1260 channel when it quits the SILC. It is ditributed inside the
1261 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1263 Added silc_server_free_client_data that will take the
1264 signoff message as argument.
1266 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1268 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1270 * Updated parts of the protocol specification to keep it up
1273 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1276 payloads in one packet.
1278 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1279 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1280 use now the new List flag.
1282 * Also deprecated the following packet types: REPLACE_ID,
1283 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1285 * Added list support for Notify packet in server.
1287 * Added silc_server_send_notify_channel_change to send the
1288 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1289 the silc_server_send_replace_id.
1291 * Added silc_server_send_notify_nick_change to send the
1292 NICK_CHANGE notify type. Deprecates the function
1293 silc_server_send_replace_id.
1295 * Added silc_server_send_notify_join to send the JOIN notify type.
1296 Deprecates the function silc_server_send_new_channel_user.
1298 * Added silc_server_send_notify_leave to send LEAVE notify type.
1299 Deprecates the function silc_server_send_remove_channel_user.
1301 * Added silc_server_send_notify_cmode and
1302 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1303 types. Deprecates the silc_server_send_set_mode function.
1305 * Added SERVER_SIGNOFF notify type to indicate that server has
1306 quit. This means that all clients on the channel from that
1307 server will drop. This can be also used when netsplit happens.
1309 Deprecated REMOVE_ID packet type since it is not needed anymore
1312 Added silc_server_send_notify_server_signoff to send the
1313 SERVER_SIGNOFF notify type. Deprecates the function
1314 silc_server_send_remove_id.
1316 Added also silc_server_send_notify_signoff to send the
1317 SIGNOFF notify type.
1319 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1320 SILC protocol from this day on. Changed the protocol
1321 specification as well.
1323 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1324 notify type. It is used between routers to notify about
1325 topic changes on a channel.
1327 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1330 * Partly updated the protocol specification to comply with the
1331 changes now made. It is still though a bit outdated.
1333 * The JOIN notify type now takes one extra argument <Channel ID>.
1334 The packet used to be destined to the channel but now the
1335 JOIN type may be sent as list thus it is impossible to
1336 destine it to any specific channel. By adding this argument
1337 it is again possible.
1339 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Added CREDITS file. The CHANGES and CREDITS file will appear
1342 in the distribution as well.
1344 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1346 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1347 types in the server's silcd/packet_receive.c.
1349 * Implemented CMODE and CUMODE to work in router environment.
1351 * Fixed minor encoding and decoding buglet from the
1352 lib/silccore/silcmode.c.
1354 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1357 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1359 * Changed all SilcConfigServer* and silc_config_server* to
1360 SilcServerConfig* and silc_server_config*, respectively.
1363 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1365 * Associated the ID (client or server ID) to the Authentication
1366 Payload to avoid any possibility of forging. Updated the
1367 protocol specification and the code accordingly.
1369 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * The RSA key length is now save to the RsaKey context in the
1372 key generation process in lib/silccrypt/rsa.c. The key length
1373 is now used to figure out the maximum size of the block allowed
1374 to be encrypted/signed.
1376 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1377 is equivalent to the silc_mp_mp2bin but does not allocate any
1380 * Changed silc_mp_mp2bin API to take length argument. If it is
1381 non-zero then the buffer is allocated that large. If zero, then
1382 the size is approximated using silc_mp_sizeinbase, which however
1385 * Created Global RNG API which is global RNG that application can
1386 initialize. After initializing, any routine anywhere in the
1387 code (including library) can use RNG without allocating a new
1388 RNG object. This was done to allow this sort of use of the
1389 RNG in code that has no chance to allocate RNG object. All
1390 applications currently allocate this and many routines in the
1391 library use this. Affected file lib/silccrypt/silcrng.[ch].
1393 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1394 it to use the Global RNG API.
1396 * Defined Authentication Payload into protocol specification that
1397 is used during SILC session to authenticate entities. It is
1398 used for example by client to authenticate itself to the server
1399 to obtain server operator privileges.
1401 Implemented this payload into the lib/silccore/silcauth.[ch].
1402 Implemented also routines for public key based authentication
1403 as the new protocol specification dictates.
1405 Moved definitions of different authentication methods from
1406 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1408 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1409 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1410 silc_pkcs_verify_with_hash functions into the file
1411 lib/silccrypt/silcpkcs.[ch].
1413 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * The client entry's userinfo pointer must be always valid.
1416 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1417 will fail since it requires the userinfo. Now, the userinfo
1418 is allocated as "" if actual userinfo does not exist. Actually,
1419 it must exist and it is totally Ok to drop client connections
1420 that does not announce the userinfo. However, we will make
1421 this workaround for now.
1423 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1424 to return the remote port by socket.
1426 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1428 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1429 SILC_SERVER_PENDING_EXEC and added an new macro
1430 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1431 data or when error occurs while processing the pending command.
1433 Added new argument `destructor' into silc_server_command_pending
1434 and to the SilcServerCommandPending object. This destructor is
1435 now called after calling the pending callback or if error occurs
1436 immediately. If error occurs the actual pending callback won't
1437 be called at all - only the destructor. The destructor may be
1438 NULL if destructor is not needed.
1440 All this applies for client library code as well. Similar
1441 changes were made there as well for the pending commands.
1443 In the client, the application must now allocate the
1444 SilcClientCommandContext with the silc_client_command_alloc
1447 * Added reference counter to the SilcServerCommandContext. Added
1448 function silc_server_command_alloc and silc_server_command_dup
1451 Same type of functions added to the client library for the same
1454 * Removed the cmd_ident from IDListData away since it is now
1455 global for all connections. It is the command identifier used
1456 in command sending and with pending commands. The affected file
1459 * Added reference counter to the SilcSocketConnection objecet to
1460 indicate the usage count of the object. The object won't be
1461 freed untill the reference counter hits zero. Currently only
1462 server uses this, and client ignores it. The client must be
1463 set to use this too later. The affected files are
1464 lib/silccore/silcsockconn.[ch]. Added also the function
1465 silc_socket_dup to increase the reference counter.
1467 This was mainly added because it is possible that the socket
1468 is removed underneath of pending command or other async
1469 operation. Now it won't be free'd and proper DISCONNECTING
1470 flags, etc. can be set to avoid sending data to connection that
1471 is not valid anymore.
1473 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1474 the connection. After that it sets SILC_SET_DISCONNECTED.
1475 It is, however, possible that the socket data is not still freed.
1476 The silc_server_packet_process now checks that data is not
1477 read or written to connection that is DISCONNECTED. The socket
1478 get's freed when the reference counter hits zero.
1480 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Changed the client operation API: channel_message operation's
1483 `sender' is now the client entry of the sender, not the nickname
1484 and the `channel' is the channel entry, not the channel name.
1486 In the private_message operation the `sender' is now also the
1487 client entry of the sender not the nickname.
1489 Affected file is lib/silcclient/ops.h and all applications
1490 using the client operations.
1492 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Moved the calling of ops->connect() from connect_to_server_final
1495 into receive_new_id functin since that is the point when the
1496 client is actually allowed to send traffic to network. The
1497 affected file is lib/silcclient/client.c.
1499 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1501 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1502 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1503 (if needs broadcasting) instead of broadcasting the packets one
1504 by one which would make a burst in the network traffic.
1506 * Added `broadcast' argument to the functions in silcd/server.[ch]
1507 silc_server_create_new_channel[_with_id] to indicate whether
1508 to send New Channel packet to primary router.
1510 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1512 * Added new function into the silcd/server.[ch] files:
1513 silc_server_create_new_channel_with_id to create new channel with
1514 already existing Channel ID.
1516 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1517 lib/silccore/silcpacket.h. This packet is used t send list of
1518 Set Mode payloads inside one packet. Server uses this to set
1519 the modes for the channels and clients on those channels, that it
1520 announced to the router when it connected to it. The protocol
1521 specification has been updated accordingly.
1523 * The silc_server_new_channel did not handle the packet coming
1524 from normal server as it normally does not send that. However,
1525 when it announces its channels it does send it. Implemented
1526 the support for that.
1528 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1529 into the file lib/silccore/id.h.
1531 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1533 * Fixed memory leaks in the functions silc_idlist_del_client,
1534 silc_idlist_del_channel and silc_idlist_del_server in the file
1535 silcd/idlist.c. All of those leaked like a sieve.
1537 * Fixed some small memory leaks in the client's function
1538 silc_client_notify_by_server.
1540 * Added functions into silcd/server.c: silc_server_announce_clients,
1541 silc_server_announce_channels and silc_server_announce_server.
1542 These functions are used by normal and router server to announce
1543 to its primary router about clients, channels and servers (when
1544 router) that we own. This is done after we've connected to the
1547 These functions effectively implements the following packet types:
1548 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1549 and SILC_PACKET_NEW_ID_LIST.
1551 * Added new functions into the silcd/packet_receive.[ch]:
1552 silc_server_new_id_list, silc_server_new_channel_list and
1553 silc_server_new_channel_user_list to handle the incoming
1554 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1556 * Added support of changing Channel ID in the function
1557 silc_server_replace_id. If the server that announces a channel
1558 to the router already exists in the router (with same name but
1559 with different Channel ID), router is responsible to send
1560 Replace ID packet to the server and force the server to change
1561 the Channel ID to the one router has.
1563 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1564 client that the Channel ID has been changed by the router. The
1565 normal server sends this to the client. Client must start using
1566 the new Channel ID as the channel's ID.
1568 Implemented handling of this new type into lib/silcclient/client.c
1569 into the function silc_client_notify_by_server.
1571 * Added new function silc_idlist_replace_channel_id into the files
1572 silcd/idlist.[ch] to replace the Channel ID.
1574 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Call silc_server_command_identify_check always when processing
1577 the IDENTIFY command in silcd/command.c
1579 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1581 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1582 send keepalive packets. The packet can be sent by clients,
1583 servers and routers.
1585 Added function silc_socket_set_heartbeat into the file
1586 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1587 If not set, the heartbeat is not performed. The actual
1588 heartbeat is implemented in the low level socket connection
1589 library. However, application is responsible of actually
1592 Added silc_server_send_heartbeat to send the actual heartbeat
1593 packet into silcd/packet_send.[ch]. Server now performs
1594 keepalive with all connections.
1596 * Added silc_task_get_first function into lib/silcutil/silctask.c
1597 to return the timeout task with shortest timeout. There was a bug
1598 in task unregistration that caused problems. TODO has been
1599 updated to include that task system must be rewritten.
1601 * The client library will now resolve the client information when
1602 receiving JOIN notify from server for client that we know but
1603 have incomplete information.
1605 * Rewrote parts of silc_server_remove_from_channels and
1606 silc_server_remove_from_one_channel as they did not remove the
1607 channel in some circumstances even though they should've.
1609 * Encryption problem encountered in server:
1611 The LEAVE command used to send the Channel Key packet to the
1612 router immediately after generating it. However, the code
1613 had earlier sent Remove Channel user packet but not immediately,
1614 ie. it was put to queue. The order of packets in the router
1615 was that Channel Key packet was first and Remove Channel User
1616 packet was second, even though they were encrypted in the
1617 reverse order. For this reason, MAC check failed. Now, this
1618 is fixed by not sending the Channel Key packet immediately but
1619 putting it to queue. However, this is more fundamental problem:
1620 packets that are in queue should actually not be encrypted
1621 because packets that are sent immediately gets encrypted
1622 actually with wrong IV (and thus MAC check fails). So, packets
1623 that are in queue should be encrypted when they are sent to
1624 the wire and not when they put to the queue.
1626 However, the problem is that the current system has not been
1627 designed to work that way. Instead, the packet is encrypted
1628 as soon as possible and left to the queue. The queue is then
1629 just purged into wire. There won't be any fixes for this
1630 any time soon. So, the current semantic for packet sending
1633 o If you send packet to remote host and do not force the send
1634 (the packet will be in queue) then all subsequent packets to the
1635 same remote host must also be put to the queue. Only after the
1636 queue has been purged is it safe again to force the packet
1639 o If you send all packets immediately then it safe to send
1640 any of subsequent packets through the queue, however, after
1641 the first packet is put to queue then any subsequent packets
1642 must also be put to the queue.
1644 Follow these rules and everything works fine.
1646 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1648 * Added new function silc_server_remove_clients_by_server to
1649 remove all client entries from ID list when the server connection
1650 is lost. In this case it is also important to invalidate all
1651 client entires as they hold the invalid server entry. This
1652 fixes fatal bug when server has lost connection and will reconnect
1655 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Made some sanity checks to silc_server_daemonise like to check
1658 whether the requested user and group actually exists.
1660 * Added sanity check to SKE's silc_ske_responder_finish to check
1661 that the public and private key actually is valid.
1663 * Invalidate the client's nickname when receiving Replace ID
1664 packet and the Client ID is being replaced. This means that the
1665 server will query the nickname if someone needs it (client)
1668 * Sort the ID Cache in client library when the ID Cache data
1669 has changed (needs sorting).
1671 * Do not allow for SILC client to create several connections to
1672 several servers. The client does not support windows right now
1673 and generating multiple connections causes weird behaviour.
1675 Irssi-silc client does support windows and can handle several
1676 connections without problems, see: www.irssi.org and SILC plugin.
1678 * Fixed some places where client was added to the IDList. The
1679 rule of thumb is following (in order to get everything right):
1680 If the client is directly connected local client then the
1681 `connection' argument must be set and `router' argument must be
1682 NULL to silc_idlist_add_client function. If the client is not
1683 directly connected client then the `router' argument must
1684 bet set and the `connection' argument must be NULL to the
1685 silc_idlist_add_client function.
1687 * The funtion silc_server_packet_send_local_channel actually did
1688 not check whether the client was locally connected or not. It
1689 does that now. Fixed a bug related to LEAVE command.
1691 * Fixed Remove Channel User payload parsing bug in server's
1692 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1694 * The server's silc_server_save_channel_key now checks also the
1695 global ID list for the channel as it might not be in the local
1696 list. Fixed a bug related to LEAVE command.
1698 * Is this the end of the [<unknown>] buglet that has been lurking
1699 around for a long time? A little for loop fix in server's
1700 silc_server_command_whois_parse that is used by both IDENTIFY
1701 and WHOIS command. At least, this was a clear bug and a cause
1702 of one type of [<unknown>] buglet.
1704 * WHOIS and IDENTIFY commands call the function
1705 silc_server_command_[whois/identify]_check function even if
1706 we are not router server.
1708 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Added --with-gmp configuration option. If set the GMP
1711 is always compiled in the SILC source tree. If not set then
1712 it is checked whether the system has the GMP3 installed. If
1713 it has then the GMP won't be compiled (the system's headers
1714 and library is used), if it doesn't have it then the GMP is
1715 compiled in the SILC source tree.
1717 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1719 * Changed RSA private exponent generation to what PKCS #1
1720 suggests. We try to find the smallest possible d by doing
1721 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1722 not security fix but optimization.
1724 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Added new config entry [Identity] to fork the server and run
1727 it as specific user and group. A patch from Bostik.
1729 * Imported Dotconf configuration library into lib/dotconf.
1730 This will be used to create the SILC configuration files later.
1731 It will appear in the distsribution after this commit.
1733 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * A big code auditing weekend happening. Auditing code for
1736 obvious mistakes, bugs and errors. Also, removing any code
1739 Removed files for being obsolete:
1741 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1742 inline in the file lib/silcutil/silcbuffer.h)
1744 o lib/silcutil/silcbufutil.c (the header has inline versions)
1746 Changed code to fix possible error conditions:
1748 o The buffer formatting routines now check that the destination
1749 buffer really has enough space to add the data. This applies for
1750 both buffer formatting and unformatting
1751 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1752 unformatting was changed to accomodate following rules:
1753 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1754 sent to the function while XXX_*STRING will not allocate or copy
1755 the data into the buffer. Instead it sets the pointer from the
1756 buffer into the pointer sent as argument (XXX_*STRING used to
1757 require that the pointer must be allocated already). This change
1758 makes this whole thing a bit more consistent and more optimized
1759 (note that the data returned in the unformatting with XXX_*STRING
1760 must not be freed now). The routines return now -1 on error.
1762 o Tried to find all code that use buffer_format and buffer_unformat
1763 and added return value checking to prevent formatting and
1764 especially unformatting errors and possible subsequent fatal
1767 o Changed ske->x and ske->KEY to mallocated pointers in
1768 lib/silcske/silcske.h. Fixed possible data and memory leak.
1770 o Added return value checking to all *_parse* functions. Fixed
1771 many memory leaks as well.
1773 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1774 so that buffer overflows would not happen. All code now also
1775 checks the return value as it can fail.
1777 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * Added reconnection support to server if the normal server looses
1780 its connection to the router (for example if router is rebooted).
1781 The server performs normal reconnection strategy implemented
1782 to the server. Affected file silcd/server.c.
1784 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Added new packet type SILC_PACKET_SET_MODE that is used to
1787 distribute the information about changed modes (for clients,
1788 channels and clients channel modes) to all routers in the
1789 network. Updated the protocol specification accordingly.
1791 Added functions into silcd/packet_send.c and
1792 silcd/packet_receive.c: silc_server_send_set_mode,
1793 silc_server_set_mode.
1795 Added new files silcmode.[ch] into lib/silccore that implements
1796 the encoding and decoding of Set Mode Payload. Added new type
1797 SilcSetModePayload. Moved the definitions of different modes
1798 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1800 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Oops, a little mistake in server's connection authentication
1803 protocol. The protocol is not ended with FAILURE but with
1804 SUCCESS if the authentication is Ok. :) Affected file is
1807 * Implemented NICK_CHANGE notify handling in server in the file
1808 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1809 the local clients on the channel. After the changing nickname
1810 in router environment snhould work and the [<unknown>] nickname
1811 should appear no more.
1813 The silc_server_replace_id function that receives the Replace ID
1814 payload now sends the NICK_CHANGE notify type also in the file
1815 silcd/packet_receive.c
1817 * Changed WHOIS and IDENTIFY command to support the maximum amount
1818 of arguments defined in protocol specs (3328 arguments). This
1819 fixed a bug that caused problems when there were more than three
1822 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Added extra parameter, command identifier, to the
1825 silc_client_send_command so that explicit command identifier
1828 Changed that ID list routines uses specific command identifier
1829 when sending WHOIS/IDENTIFY requests to the server so that they
1830 can be identified when the reply comes back.
1832 Affected files lib/silcclient/command.[ch],
1833 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1835 * Added `sender' argument to silc_server_packet_send_to_channel
1836 to indicaet the sender who originally sent the packet to us
1837 that we are now re-sending. Ignored if NULL. Affected file
1838 silcd/packet_send.[ch].
1840 * Added some server statistics support in silcd/server_internal.h
1841 SilcServerStatistics structure and around the server code. Also
1842 send some nice statistics information when client is connecting
1845 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * Fixed channel ID decoding in server's JOIN command reply in
1848 silcd/command_reply.c
1850 * Fixed braodcasting of replace ID payload to not to send it if
1851 we are standalone server in silcd/packet_receive.c.
1853 * Fixed all channel message sending routines to not to send
1854 packets to clients that has router set, since they are routed
1855 separately in the same function earlier. Affects file
1856 silcd/packet_send.c and all channel packet sending functions.
1858 * In USERS reply, res_argv[i] are not allocated, the table
1859 is allocated. Thus changed that free the table, not its
1862 * In server's whois_check and identify_check if the client is
1863 locally connected do not send any WHOIS commands - they are not
1866 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1868 * Fixed some minor bugs in client when sending WHOIS command. The
1869 arguments was in wrong order.
1871 * Removed statis function add_to_channel from server in
1872 silcd/command.c that was previously used with the joining but
1875 * Tested USERS command in router environment successfully with two
1876 routers, two servers and two clients.
1878 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Reorganized the USERS command and command reply in client library
1881 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1882 When the command is given by user we register a pending command
1883 callback that will reprocess the command after the reply has been
1884 received from the server. When reprocessing the packet we then
1885 display the information. Thus, the USERS information is displayed
1886 now in the command callback instead of in the command reply
1887 callback. The processing of the command is same as previously
1888 when server has sent the command reply in the JOINing process.
1890 * Added to USERS command in silcd/command_reply.c to join the client,
1891 we didn't use to know about, to the channel after we've created
1892 a client entry for it. Also, for clienet we did know already still
1893 check whether it is on the channel or not and add it if not.
1895 * Removed silc_server_command_join_notify as the function and its
1898 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Changed the client's pending command handling to the same as the
1901 server's pending command handling. It is also now possible to
1902 execute command reply functions from other command reply
1903 function as the function callbacks for commands and command
1904 replies are one and same. The pending commands are not static
1905 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1906 in client connection context. Thus, pending commands are server
1907 connection specific as it is convenient.
1909 Changed the function silc_client_command_pending and
1910 silc_client_command_pending_del and added new function
1911 silc_client_command_pending_check. Removed the
1912 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1915 * Added cmd_ident, current command identifier, to the client
1916 connection context in lib/silcclient/client.h to keep track on
1917 command identifiers used in command sending. Client's command reply
1918 function handling now supports the mandatory command identifiers.
1920 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1921 funtions in client to fully support pending command callbacks.
1923 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1924 as one of the arguments to the application in the command reply
1927 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1928 before first releasing SILC but came back. Now it is removed again
1929 and should come back nomore. The FORWARDED flag was used only
1930 by the JOINing procedure by forwarding the command packet to router.
1931 Now, the JOINing procedure has been changed to more generic (due
1932 to various router environment issues) and FORWARDED is not needed
1933 anymore for anything. The protocol specification is yet to be
1936 Now, removed silc_server_packet_forward from server and the flag
1937 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1939 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Renamed NAMES command to USERS command. The NAMES was named that
1942 due to historical reasons. Now it is renamed. Also, rewrote
1943 parts of the USERS command. The nickname list is not sent anymore
1944 by the server. Only Client ID and mode lists are sent in the USERS
1945 command. Changed this also to the protocol specification.
1947 The client now resolves the names and stuff after it receives
1948 the USERS list from the server when joining to the channel.
1950 * WHOIS and IDENTIFY commands has been changed to support multiple
1951 Client ID's per command. One can now search for multiple users
1952 in the network by sending only one WHOIS or IDENTIFY command.
1953 Changed the code and the protocol specifications.
1955 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1956 uses silc_server_command_whois_parse to parse the request. */
1958 * If normal server, do not parse the WHOIS and IDENTIFY requests
1959 before sending it to the router. Saves some time.
1961 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Fixed JOIN command on client library. Wrong number of arguments
1964 used to crash the client.
1966 * Added silc_server_channel_has_global function to check whether
1967 channel has global users or not.
1969 * Added silc_server_channel_has_local function to check whether channel
1970 has locally connected clients on the channel.
1972 * The silc_server_remove_from_one_channel now checks whether the
1973 channel has global users or not after given client was removed from
1974 the channel. It also checks whether the channel has local clients
1975 on the channel anymore. If it does not have then the channel entry
1976 is removed as it is not needed anymore.
1978 * The silc_server_notify now checks on JOIN notify whether the joining
1979 client is one of locally connected or global. If it is global then
1980 the channel has now global users on the channel and that is marked
1981 to the channel entry. Also, it now saves the global client to
1982 global list who is joining and JOINs it to the channel. This is
1983 for normal server, that is.
1985 Changed silc_server_send_notify_on_channel,
1986 silc_server_packet_relay_to_channel and
1987 silc_server_packet_send_to_channel check if we are normal server
1988 and client has router set (ie. global client) do not send the
1989 message to that client, as it is already routed to our router.
1991 * Implemented LEAVE notify type handling in silc_server_notify
1994 * Tested LEAVE command in router environment successfully. Tested
1995 with two routers, two servers and two clients.
1999 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2001 * Implemented SIGNOFF notify type handling in silc_server_notify
2004 * silc_server_remove_id now removes the client entry from all channels
2005 it has joined and thusly sends SIGNOFF notify type.
2007 * Rewrote the NAMES list generation in server by removing two excess
2008 loops. The lists are created now inside one loop.
2010 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2012 * silc_server_remove_channel_user checks now also global list
2013 for channel and client.
2015 * silc_server_new_channel_user checks now both local and global
2016 list for channel and client. Fixed a bug in client id decoding.
2017 Used to decode wrong buffer.
2019 * silc_server_channel_message checks now both local and global
2020 list for channel entry.
2022 * Tested channel joining (hence JOIN) in router environment
2023 successfully. Tested with two routers, two servers and two
2026 * Tested channel message sending in router environment successfully.
2028 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Added silc_server_save_channel_key into server.[ch] to save the
2031 received channel key in Channel Key payload processing. It is
2032 also used in JOIN command reply handling.
2034 Equivalent function silc_client_save_channel_key added into
2035 client.[ch] into client library.
2037 * Changed JOIN command reply to send information whether the channel
2038 was created or not (is existing already) and the channel key
2039 payload. Changed protocol specs accordingly.
2041 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2042 the request was sent by ID and not by nickname. Crashed on
2045 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2048 now correctly save the received data.
2050 * silc_server_free_sock_user_data now notifies routers in the
2051 network about entities leaving the network.
2053 At the same time implemented functions silc_server_remove_id
2054 and silc_server_send_remove_id to receive and send REMOVE_ID
2055 packets. The packet is used to notify routers in the network
2056 about leaving entities. The ID removed will become invalid in
2059 * Added function silc_idlist_del_server into server. Removes and
2060 free's server entry from ID list.
2062 * silc_server_private_message function now checks, if we are router,
2063 that the destination ID really is valid ID, naturally.
2065 * In router when NEW_ID packet is received (for new client) the
2066 hash of the Client ID is saved in the ID Cache but the
2067 client->nickname is set to NULL, instead of putting the hash
2070 IDENTIFY command now also checks that client->nickname must be
2071 valid. If it is not if will request the data from the server who
2072 owns the client. Added new function
2073 silc_server_command_identify_check.
2075 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2076 to set the command to already allocated Command Payload.
2078 * Tested private message sending in router environment with two
2079 routers, two servers and two clients. Fixed minor bugs and now
2082 * Fixed segfault from client's NAMES command. Used to crash if
2085 * Forwarded packets must not be routed even if it is not destined
2086 to the receiver. Changed server code comply with this.
2088 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added `require_reverse_mapping' boolean value to ServerParams
2091 structure. If TRUE (not default) the server will require that
2092 the connecting host has fully qualified domain name.
2094 If the reverse mapping is not required and hostname could not be
2095 found the IP address is used as hostname.
2097 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Implemented version string checking to both client and server.
2100 The check is incomplete currently due to the abnormal version
2101 strings used in development version of SILC.
2103 * Changed all command functions in server to use the new
2106 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Changed char *data to unsigned char *data in ID Cache system to
2109 support binary data as ID Cache data. Changed code to support
2110 binary data in lib/silccore/idcache.c.
2112 * Renamed silc_server_packet_relay_command_reply to
2113 silc_server_command_reply as it is normal packet receiving
2114 function. Rewrote the function to accept command replys for
2115 servers and not only for clients.
2117 * Mark remote router always as registered server if we are connecting
2118 to it. Otherwise, commands sent by the router to us are ignored.
2120 * All ID List find routines now returns the ID Cache Entry pointer
2121 as well if requested.
2123 * WHOIS command works now in router environment, tested with two
2124 routers, two servers and two clients.
2126 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2127 in router environment (as it is almost equivalent to WHOIS) but
2128 hasn't been tested thoroughly. Added new functions:
2130 silc_server_command_identify_parse
2131 silc_server_command_identify_send_reply
2132 silc_server_command_identify_from_client
2133 silc_server_command_identify_from_server
2135 * Disabled route cache adding because adding two different ID's with
2136 same IP replaces the old cache entry thus giving wrong route.
2137 The entry->router->connection is always the fastest route anyway
2138 so route cache may not be needed. Of course, new routes maybe
2139 established after receiving the ID when the entry->router->connection
2140 might not be anymore the most optimal.
2142 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2144 * Add route cache for received ID for fast routing.
2146 * Added silc_server_packet_route to route received packet on router
2147 that is not destined to us.
2149 * Renamed silc_server_get_route to silc_server_route_get.
2151 * Added id_string and id_string_len fields into SilcServer to
2152 include encoded ServerID for fast comparing without excess
2153 encoding of the ID's.
2155 * Cleaned up WHOIS command on server side. Added following static
2158 silc_server_command_whois_parse
2159 silc_server_command_whois_check
2160 silc_server_command_whois_send_reply
2161 silc_server_command_whois_from_client
2162 silc_server_command_whois_from_server
2164 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2165 arguments in command replies. All command functions should be
2166 updated to use this macro.
2168 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Minor typo fixes on command reply handling on server.
2172 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Added silc_server_command_add_to_channel internal routine to add
2175 the client to the channel after router has created the channel and
2176 sent command reply to the server.
2178 * Added generic silc_server_send_command to send any command from
2181 * Use static buffer with ID rendering instead of duplicating data.
2183 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2185 * Fixed a channel user mode bug when joining to a channel server gave
2186 everybody channel founder rights, oops.
2188 * We mark ourselves as the router of the incoming server connection
2189 if we are router ourselves. This way we can check in some packet
2190 sending functions whether it is locally connected server. For
2191 incoming router connections we put NULL.
2193 * For router sending packets locally means now always sending the
2194 packet cell wide; to local clients and local servers. For normal
2195 server sending packet locally means sending it to only local
2198 * Fixed the JOIN command to really work in router environment. If the
2199 channel is created it is always created by the router. Router is
2200 also responsible of making the initial joining to the channel,
2201 sending JOIN notify to the sending server and distributing
2202 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2203 does not exist server doesn't do anything else but forward the
2204 command to the router which performs everything.
2206 * Added silc_server_send_channel_key function to send the Channel Key
2209 * Added silc_server_create_channel_key to create new channel key. The
2210 channel key is now re-generated everytime someone joins or leaves
2211 a channel, as protocol dictates. Note: channel->key_len is the
2214 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2216 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2217 packet_receive.[ch] to separate packet sending and receiving
2218 routines. The server.[ch] now includes everything else including
2219 actual packet processing (writing and reading data) and other
2222 Renamed silc_server_private_message_send_internal to
2223 silc_server_send_private_message. The routine is still though
2224 used only to relay private messages as server does not send
2225 private messages itself.
2227 Renamed silc_server_new_channel to silc_server_create_new_channel
2228 and added new function sicl_server_new_channel that handles the
2229 incoming New Channel packet. Added also new sending function
2230 silc_server_send_new_channel to send New Channel Payload.
2232 * Added new function silc_server_notify to process incoming notify
2233 packet to the server/router. Server may then relay the notify
2234 to clients if needed.
2236 * Added new function silc_server_new_channel_user to process incoming
2237 New Channel User packet. Router will redistribute the packet and
2238 send JOIN notify to its local clients and locally connected servers
2239 if needed. Normal server will send JOIN notify to its local client
2240 on same channel when received this packet. Added also corresponding
2241 sending function silc_server_send_new_channel_user to sent the
2244 * Added boolean route argument to send_notif_to_channel and
2245 packet_send_to_channel functions to attempt to route the packet
2246 if it is TRUE and send only locally if it is FALSE.
2248 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * silc_server_replace_id now broadcasts the received replace ID
2251 packet if it is not broadcast packet already. The router must
2252 broadcast to inform other routers about changed ID.
2254 * Added backpointer to server's router into SilcServer context in
2255 silcd/server_internal.h.
2257 * Fixed silc_server_packet_broadcast to send correct broadcast
2260 * The channel key is now distributed to the local client as soon
2261 as it is received from the router (in router environment) so that
2262 no other packet may be sent for the channel until client has
2265 * silc_server_remove_channel_user now broadcasts the received
2266 Remove Channel User packet if it is not broadcast packet already.
2267 The router must broadcast to inform other routers about removed
2270 * Added users field into SilcPacketContext that is a reference count
2271 of the context. One can increase the reference count by calling
2272 silc_packet_context_dup which is now changed to just increase the
2273 reference count instead of duplicating the data. The reference
2274 count is decresed by calling silc_packet_context_free that will
2275 free the data after the reference count hits zero.
2277 For now on the packet context and everything allocated into it
2278 (including the raw packet from network) must be freed by calling
2279 the new silc_packet_context_free function. Added also new function
2280 silc_packet_context_alloc that must be used now to allocate the
2281 context. This also means that if a routine is asynchronous from
2282 silc_[client/server]_packet_parse_type the packet context must
2283 be duplicated by calling silc_packet_context_dup. Otherwise it
2284 gets free'd after silc_[client/server]_packet_parse_type returns.
2285 Also, one must remember that if packet is duplicated then its
2286 reference count must be decresed by calling the free function as
2287 many times as it was duplicated.
2289 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2290 from both client and server.
2292 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Made joining to a channel working in router environment.
2296 * Cleaned up JOIN command on server side and create function
2297 silc_server_command_join_channel internal routine to make the
2300 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Changed silc_command_pending list to SilcDList. Also, added
2303 `ident' field to SilcServerCommandPending structure to identify
2304 the reply and to call correct callback.
2306 Added silc_server_command_pending_check function to replace the
2307 corresnponding macro. The silc_command_pending list is not
2310 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2311 to set identifier to previously allocated Command Payload. It
2312 is used to set identifier for command when resending Command
2315 * Added silc_command_payload_encode_payload to encode Command
2316 Payload buffer from SilcCommandPayload structure.
2318 * Added silc_argument_payload_encode_payload to encode Argument
2319 payload buffer from SilcArgumentPayload structure.
2321 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Changed WHOIS command to support router connection on server side.
2324 The whois request is always sent to router unless the server is
2325 standalone server. After server has received the reply from the
2326 router will it send the reply to the client.
2328 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2329 broadcast received broadcast packet. The function is used only
2330 by router. The broadcast packet is always sent to the router's
2333 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2334 render given ID to printable string, for log files for example.
2336 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Made basic router to router connections working. At least they
2339 can now connect to each other but nothing really works the way
2340 they are supposed - yet.
2342 * Added new initiator token to RouterConnection configuration
2343 file in silcd/serverconfig.[ch]. It is used to tell whether we
2344 are the initiator to the remote router or whether we'll expect
2345 the other end to connect.
2347 * Moved registering of listener task to silc_server_init, hence
2348 the server starts listenning as soon as it is run, even if it
2349 does not have connections to other routers. Let's see how well
2352 * Changed default connection retry timeouts for more suitable in
2355 * Removed cipher and such arguments from silc_idlist_add_client
2356 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2357 Added new function silc_idlist_add_data to add the keys and stuff
2360 * Added SilcIDListData structure and added it to SilcClientEntry
2361 and SilcServerEntry as their first field in the structure. This
2362 way we can explicitly cast the ID entries to the SilcIDListData
2363 structure and get common data for the entries. In past, we had
2364 to first check what type of connection it is and then cast it to
2365 correct ID entry type. Now, we can directly cast the opaque
2366 pointer to the SilcIDListData (no matter what ID entry it actually
2367 is) and get the data needed.
2369 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2372 in some circumstances even if threre were timeout tasks, though not
2373 IO tasks, but tasks anyway. Now fixed.
2375 * Defined SilcServerConnection structure to hold connection specific
2376 stuff about directly connected servers and routers. The definition
2377 is currently in silcd/server_internal.h. I thought about having
2378 a bit more important role fro this struct but for now it is used
2379 only when connecting to other server (or router actually).
2381 * Added connecting retry support in server when connecting to
2382 router(s). The retry feature implement exponential backoff
2383 algorithm. Also, added SilcServerParams structure to hold default
2384 parameters for server. For now, it include these retry settings
2385 and are hard coded. After server is moded to be as Silc Server
2386 Library this structure will be more important.
2388 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Changed client librarys channel->clients table to SilcList and
2391 changed code accordingly.
2393 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Changed client's channel table to SilcList and changed code
2396 accordingly. Also changed SilcChannelClientEntry to include back-
2397 pointer to the channel so that client entry can use that structure
2398 as list as well and we have fast cross-reference to the channel.
2399 This change dramatically decreased the complexity of channel
2400 handling with client entry and vice versa (removed one extra
2401 loop when searching for channel entry from many functions).
2403 * Changed server->sim from table to SilcDList and changed code
2406 * NAMES command can now be used from user interface. It will show
2407 the user list on the channel, neatly.
2409 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2410 Code now saves realname of the user if it becomes available.
2412 * Renamed configure.in to configure.in.pre and made ./prepare
2413 script to automatically add correct version string to
2414 configure.in which it creates from configure.in.pre.
2416 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * NAMES command reply now shows users mode with the nickname when
2421 * Moved silc_client_ch[u]mode[_char] functions from
2422 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2423 place sucks, they are utility functions and should be in some
2426 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2428 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2431 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Added TRQ (efficient deque and list library) into lib/trq. This is
2436 a very good list library that is currently used in the SILC. Defined
2437 SilcList API over the library because I didn't like the API very
2438 much. See lib/trq/silclist.h for the API and examples of how to
2439 use the API. Fixed various places in the code to use the new
2440 SilcList API. The SilcList is meant for lists that has a structure
2441 already defined as a list. It is not suitable to add just some
2442 context to the list (in TRQ, the context is the list actually).
2444 So, I defined SilcDList that can be used for the purpose where
2445 predefined list structure does not exit. This can be used as
2446 such list. Now some context just can be added to the SilcDList.
2447 Currently this list is not used in the SILC just yet, though there
2448 are a lot places where this can replace dynamically allocated
2449 tables and I will fix these places, later, to use SilcDList.
2450 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2451 and use TRQ internally).
2453 Also fixed some annoying warning messages that the original TRQ
2454 code generated. Also minor changes to TRQ's Makefile.in.
2456 * Added support for querying by Client ID to both WHOIS and
2457 IDENTIFY commands into server, as required by the protocol.
2459 * Removed method function pointers from SilcBuffer structure. They
2460 weren't used to anything and just increased the context size for
2461 no good reason. This change also made silc_buffer_alloc and
2462 silc_buffer_free functions inline functions.
2464 * Disabled command flooding detection support until it's fixed so
2465 that it accepts commands in but does not execute them more than once
2468 * Added silc_net_localhost(), to return local hostname, into
2469 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2470 that must be initialized before calling silc_client_init.
2472 * Added new function: silc_server_send_notify_on_channels to send
2473 notify messages to all channels client has joined. It is assured
2474 that the message is sent only once per client.
2476 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2477 lib/silcutil/silcutil.[ch] as silc_format function. The new
2478 function is generic and is used by server as well, not only by
2479 the logging routines.
2481 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2482 the provided version string was not acceptable. Added new function:
2483 silc_ske_check_version into lib/silcske/silcske.h. The function
2484 must be implemented by the application (client or server) and it
2485 does not reside in the SKE library. The function checks the version
2486 string remote end sent.
2488 * Added back pointers (to opaque context and to SilcSocketConnection)
2489 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2491 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2492 duplicate packet context structure.
2494 * Changed `notify' client operation to send same arguments as client
2495 receives from server except for ID's. ID's are mapped to correct
2496 ID entry and that is returned. Also, if channel entry is not sent
2497 by server but the notify is for channel the channel entry is sent
2498 to application (otherwise application doesn't know that it is for
2499 channel (library gets it from packet's Destination ID)).
2501 * Added silc_client_remove_from_channels into client library to
2502 remove a client from all channels it has joined to. Used when
2503 received SIGNOFF notify from server. Added also new function
2504 silc_client_replace_from_channels to replace old ID entry with
2505 new ID entry on all channels. Used when received NICK_CHANGE
2508 * Fixed ID Cache list handling in silc_idlist_get_client in
2509 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2510 to get (or query) client by ID.
2512 * Updated TODO list.
2514 * Added connection authentication status message defined by the
2515 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2516 support for these into the code in client and server side.
2518 * Added generic function silc_client_send_command to send any command
2519 with variable argument list. Application should use this function
2520 to send commands if the command functions provided by the library
2521 does not suite for the application's user interface needs.
2523 * Added new `failure' client operation. Application is notified about
2524 received failure packet if client is executing a protocol. In this
2525 case the protocol's execution has failed.
2527 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2528 is required by the protocol.
2530 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2531 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2534 * Added status flag to SilcSKE object to indicate realtime status
2535 of the SKE protocol.
2537 * Application receives now exactly same command reply arguments as
2538 the library receives from server. However, if ID is received the
2539 corresponding ID entry is returned to the application (eg. Client
2540 ID is mapped to correct SilcClientEntry entry and that is returned).
2541 Changed command_reply client operation due to this change.
2543 * Changed all ID's in commands and in command replys as ID Payloads.
2544 Change affected both client and server side codes.
2546 All ID's sent in SILC network (with execption of ID's in SILC
2547 Packet header) are sent in ID Payload to support variable length
2550 * Server now notifies nick changes and notifies all clients on
2551 the channels about the new nickname (about the new Client ID,
2554 * Implemented CMODE command to change channel modes. Supports all
2555 channel modes defined by the protocol specs except ban and invite
2556 lists. (Also, private channel key mode is supported but support for
2557 setting private channel key in client is missing, thus, this mode
2558 has no effect on client side (except that server requires that the
2559 client uses private channel key and normal channel traffic does not
2562 Also, invite mode works per se, but INVITE command does not work
2563 yet correctly, so you can set channel as invite only channel but
2564 inviting clients to the channel does not work (it is yet to be
2565 thought what's the best way to do it).
2567 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2568 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2569 Implemented CUMODE command to change user's mode on the channel.
2570 Supports all modes defined by the protocol specs.
2572 * Added NAMES command reply to return users modes on the channel.
2574 * Removed unnecessary and slow ciphers from lib/silccrypt.
2576 * Set SO_KEEPALIVE option to connection sockets by default.
2578 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2580 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2581 redefined the Notify Payload into protocol specs.
2583 * Added silc_id_payload_parse_id to get ID directly from raw
2586 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2588 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2589 accept searching by Client ID as well.
2591 * Added support for LEAVE and SIGNOFF notify types in client library.
2593 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2594 to parse ID Payload from raw data.
2596 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2598 * Added flags parameter into silc_ske_assemble_security_properties
2599 function in lib/silcske/silcske.[ch].
2601 * Changed notify client operation to fit better for notify messages
2602 sent by server. The notify payload received from server is now
2603 passed to the application (after parsing it to SilcNotifyPayload).
2604 It is application's responsibility to retrieve the arguments
2605 from the payload and show the message the way it wants. The message
2606 sent by server is implementation specific.
2608 * Changed public keys to comply with the protocol specification.
2609 Old public keys are not supported anymore and are not compatible.
2611 * Removed nickname from Channel Payload as the latest draft removed
2612 it. The client must resolve the nickname from the NAMES command
2613 reply received when it joined the channel.
2615 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2617 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Fixed some errors in protocol specification drafts.
2621 * Created lib/silccore/silcnotify.c to implement Notify Payload
2622 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2623 generic payloads described by protocol specifications. The file
2624 includes implementations for ID Payload and Argument Payload.
2626 * Changed Command Payload implementation to use the new Argument
2627 Payload. Changed command_xxxx_payload to command_payload_xxxx
2628 to comply with SILC coding conventions.
2630 * Added suppport for Argument Payload handling in Notify Payload
2631 implementation as protocol requires it. Added the new support
2632 into server and client lib as well.
2634 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2636 * Added support for multiple nicknames on same channel. [n] is
2637 added locally to the nickname if there are more than one same
2638 nicknames on the channel.
2640 * Server now sends all nicknames that matched WHOIS request.
2641 Client also shows the list received from server.
2643 * Added TOPIC command to client side. User can now set and show
2644 current topic on channel.
2646 * Added MOTD command to client and server. Also, server sends the
2647 motd when client connects to the server.
2649 * Changed version strings to comply ISO 8601.
2651 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2653 * Fixed protocol error handling in client library. It should now
2654 cope even if the SKE fails for some reason.
2656 * Made new protocol specification drafts for submitting to IETF.
2658 * Implemented TOPIC command to server in silcd/command.c.
2660 * Added two new notify types into lib/silccore/silcnotify.h:
2661 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2662 notify nickname change and topic setting/change on a channel.
2664 * API change of command_reply operation in client library. The
2665 application gets now the status type received from server as well.
2667 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2671 * Cras fixed and optimized the packet handling even further and
2672 it should work now. Minor change to the prototype of function
2673 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2675 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Added new function into lib/silcutil/silcschedule.[ch]:
2678 silc_schedule_with_fd to select() a specified fd. The function
2679 returns after timeout expires or data arrives or goes. The
2680 function is used by packet routines to wait that all data is
2681 received from network.
2683 * Fixed data reading from network in lib/silccore/silcpacket.c.
2684 The code now assures that all data is read from the fd and then
2685 continues packet processing. This was a bug fix since the code
2686 used to drop some data in some circumstances.
2688 * Added new function into lib/silcclient/client.[ch]:
2689 silc_client_start_key_exchange to start key exchange after
2690 connection has been established to server. The code internally
2691 now uses this funtion but its main purpose was to provide it
2692 for applications that perform their own connecting. After
2693 application has created a connection it merely calls this
2694 function to start the key exchange between client and server.
2695 The library takes care of everything else after that.
2697 Updated also lib/silcclient/README to explain the usage of
2700 * Do not send to application information that connection has
2701 been established. Application gets notified it by connect
2704 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Applied cras's patch to add silc_schedule_one function. The
2707 function runs scheduler once and returns.
2709 * Fixed the scheduler after cras messed it up. The timeout
2710 handling works now as it's supposed to work.
2712 * Added into lib/silccore/ silcnotify.h to include notify
2713 message types support. Changed silc_server_send_notify*
2714 functions, in server.[ch], to support those new notify types.
2715 Added the support for the notify types into client library,
2716 as well. Added new notify client operation into ops.h in
2719 * Changed silc_server_packet_send_to_channel to send normal
2720 packets instead of just channel message packets. The function
2721 is now used to send the notify packets to channels. It is not
2722 used to send channel message packets anymore, as server never
2725 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2726 va_arg()s as it seems to require it nowadays. I guess, if SILC
2727 is compiled with older va_arg() the new code should work anyway.
2729 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Splitted core library. Core library (lib/silccore) includes
2732 now only SILC protocol specific core (and common) components.
2733 Created new utility library (lib/silcutil) that includes more
2734 generic purpose stuff. The stuff for util library was taken
2735 from the old core library. This was minor and easy split.
2737 * Created SILC Client Library (lib/silcclient) that includes
2738 implementation of the SILC client without user interface. This
2739 was major move from silc/ directory. The code has been changed
2740 so that it is transparent towards the user interface. The
2741 silc/ directory includes now the same user interface as before
2742 and it uses the new client library. Read lib/silcclient/README.
2743 Basicly, the client library performs everything else related
2744 to SILC except user interface handling. Also, configuration
2745 files are considered to be part of user interface and library
2746 does not handle them.
2748 This change also changed a lot of structures, function naming etc.
2749 Most important change was that SilcClientWindow object was
2750 renamed to SilcClientConnection in the client library. Created
2751 also new file lib/silcclient/ops.h. Also added new files
2752 silc/local_command.[ch] and silc/client_ops.[ch].
2754 All these changes were made to make it easier for user interface
2755 designers to create what ever user interface for the SILC client
2758 It is also expected that the server will be moved to lib
2759 directory as well and SILC Server Library will be created;
2760 sometimes in the future.
2762 * Removed Local commands from lib/silccore/silccommand.h as
2763 they are application specific and new client library does not
2764 handle any of those anymore.
2766 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2767 old client implementation in silc/.
2769 * Added support for callback functions in SILC_LOG_* macros.
2770 Application can now set its own callbacks that will be called
2771 instead of using the default functions that will always print
2772 the debug messages to stderr (or stdout). Also, debugging can
2773 now be disabled by setting silc_debug to FALSE and re-enabled by
2774 setting it to TRUE. Note, that logging will still work even
2775 if debugging is disabled.
2777 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2778 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2779 silc_log_reset_debug_callbacks.
2781 * To enable debugging in silc client one must give now -d
2782 option on command line.
2784 * Changed silc_schedule_init to automatically allocate task queues
2785 if they are not allocated before calling it.
2787 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Added GMP 3.1 into math library.
2791 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2794 a channel in SILC network. The packet is used by servers and
2795 routers to notify other routers that user has left a channel.
2796 This little feature was missing until now. Added the feature
2797 to protocol specification as well.
2799 Added functions: silc_server_send_remove_channel_user and
2800 silc_server_remove_channel_user into server.[ch].
2802 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2803 lib/silccore/silcpacket.h. However, they are not implemented
2806 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Fixed joining to a channel and sending channel messages
2809 between server and router. The channel message sending should
2810 now work inside a cell.
2812 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Fixed the private message sending between server and router.
2815 The private message sending should now work inside a cell.
2817 * Added silc_server_replace_id into server.[ch] to replace
2818 existing ID in the SILC network.
2820 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2821 and silc_idlist_replace_server_id into idlist.[ch] in server.
2823 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Fixed the server to server connections. Server can again now
2826 connect to router. Router to router connections probably does
2829 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Added dynamic protocol registering support. Now protocols can
2832 registered and unregistered on the fly. Patch by cras.
2834 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Added lib/contrib directory to hold routines that some platforms
2837 don't have but are needed by SILC.
2839 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2840 into lin/contrib to provide getopt() and getopt_long() for
2841 those who don't have it.
2843 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * Added AWAY command to client. When away message is set and
2846 client receives a private message packet the client automatically
2847 replies to the sender with the away message.
2849 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2850 bug seemed to be the cause of recent problems when compiling
2853 * Added version detection support to SKE protocol specification
2854 and added the new changes to the SKE implementation as well.
2855 There were other minor changes in the SKE protocol as well.
2857 Many changes in lib/silcske/silcske.[ch] and in
2858 lib/silcske/payload.[ch].
2860 * Added ^U functionality, clear input line. Patch from cras.
2862 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Mainly small bugfixes on core library. Fixed some debugging
2865 logging and buffer overflow in silclog.c.
2867 * Updated config.sub and config.guess on the distribution tree.
2869 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Added command lagging support in server. Client may execute
2872 commands now only once in two seconds.
2874 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Optimized packet reception. MAC computation and checking is now
2877 also more optimized. A lot previously duplicated code is now
2878 used as generic by both client and server.
2880 * Fixed key pair generation in clientutil.c
2882 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Added into lib/silccore/silcbufutil.[ch] new function;
2885 silc_buffer_realloc.
2887 * Moved generic packet sending/encryption functions to
2888 lib/silccore/silcpacket.[ch] from client and server. Some
2889 rewriting of the functions.
2891 * Moved all generic packet reception/decryption functions to
2892 lib/silccore/silcpacket.[ch] from client and server. The
2893 packet processing is now much cleaner in both client and server.
2894 These were major changes in both client and server.
2896 * Created many common functions in server to do packet sending.
2897 Previously code were duplicated a lot, this has been removed
2900 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * Rewrote major parts of the ID cache system. Don't know
2903 whether it is better now or not but at least the API is more
2906 * Major rewrite on ID cache stuff on client because of the ID
2907 cache API changes. Added idlist.c to client.
2909 * Also major rewrite on ID cache stuff on server as well.
2910 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2911 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2912 in hand, instead they are all put into the ID cache system now.
2913 All server_idlist_* routines uses ID cache now instead of
2914 traversing its own lists (those lists does not exist anymore).
2915 SilcIDList though still exists. Also, SilcXXXEntry's are
2918 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2920 * Finally made the SKE implementation compliant to the protocol
2921 specification. All mp integers are now binary encoded as
2922 opposed being HEX encoded.
2924 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2927 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2928 functions: silc_[encode/decode]_pem. Also added function
2929 silc_encode_pem_file to PEM encode with newlines ('\n') for
2932 * SILC public keys are now encoded either PEM or binary. Same
2933 option is for private keys as well. By default private keys
2934 are binary encoded and public keys PEM encoded. Silly HEX
2935 encoding were removed.
2937 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2938 function to create fingerprints.
2940 * Fixed a bug in SHA1; does not change the original data anymore.
2942 * Partly implemented INFO command on client and server side.
2943 Fixed CLEAR command. Changes to SERVER command; show current
2944 server(s) when giving command without arguments. Added
2945 VERSION command to client.
2947 * Added check to server that unregistered connections cannot
2948 execute commands (unless it is specificly allowed).
2950 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Fixed screen refresh.
2954 * Fixed channel joining bug from client. On some circumstances
2955 client tried to join to a channel it had already joined.
2957 * Added public key verification process into client's protocol.c.
2958 The client now verifies the public key from user and saves
2959 it into ~./silc/serverkeys/ directory.
2961 Added into: clientutil.[ch]: silc_client_verify_server_key.
2963 * Changed SKE protocol's silc_ske_initiator_finish function
2964 to accept callback function that verifies the received public
2965 key. Removed old silc_ske_verify_public_key function.
2967 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2970 silc_pkcs_private_key[_data]_set.
2972 * Made the password and public authentication more cleaner in
2973 server's protocol.c.
2975 * Removed historic and obsolete protocol `channel_auth' from
2976 both client and server.
2978 * Removed wrong way of sending command status messages from
2979 server to client in server's command.c. The old way violated
2980 protocol specification.
2982 Changes to silccore/silccommand.[ch]: removed
2983 silc_command_encode_status_payload -> not needed anymore,
2984 changed silc_command_encode_payload_va to accept extra
2985 argument on variable argument list. The argument type must
2986 now be provided to the function. Also, added new function:
2987 silc_command_encode_reply_payload_va which is same as
2988 normal command_encode_payload_va except command status type
2989 is provided as extra argument.
2991 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Added ~./silc directory handling. The directory includes the
2994 public and private keys for the client.
2996 Added silc_client_check_silc_dir, silc_client_create_identifier
2997 and silc_client_load_keys.
2999 * Implemented SILC protocol compliant public key. Added public
3000 and private key saving to and loading from files.
3002 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3003 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3004 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3005 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3006 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3008 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3009 silc_pkcs_load_[public/private]_key.
3011 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Added silc_server_get_route (route.[ch]) to get connection
3014 data for the fastest route for given ID.
3016 * Implemented INVITE command on client and server. The command
3017 were re-defined in the SILC Protocol Specification and the
3018 implementation now complies with the specification.
3020 * Implemented PING command on client and server.
3022 * Implemented NAMES command on client and server. The server side
3023 supports currently only normal server not router server yet.
3024 Some changes to NAMES definition in SILC protocol specification.
3026 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3028 * Implemented LEAVE command on client and server.
3030 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3031 again. This change was made to the protocol as well. Server
3032 should not violate the protocol specification anymore.
3034 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3037 was tested. SOCKS4 was not but should work anyway.
