1 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed channel ID decoding in server's JOIN command reply in
6 * Fixed braodcasting of replace ID payload to not to send it if
7 we are standalone server in silcd/packet_receive.c.
9 * Fixed all channel message sending routines to not to send
10 packets to clients that has router set, since they are routed
11 separately in the same function earlier. Affects file
12 silcd/packet_send.c and all channel packet sending functions.
14 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
16 * Fixed some minor bugs in client when sending WHOIS command. The
17 arguments was in wrong order.
19 * Removed statis function add_to_channel from server in
20 silcd/command.c that was previously used with the joining but
23 * Tested USERS command in router environment successfully with two
24 routers, two servers and two clients.
26 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Reorganized the USERS command and command reply in client library
29 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
30 When the command is given by user we register a pending command
31 callback that will reprocess the command after the reply has been
32 received from the server. When reprocessing the packet we then
33 display the information. Thus, the USERS information is displayed
34 now in the command callback instead of in the command reply
35 callback. The processing of the command is same as previously
36 when server has sent the command reply in the JOINing process.
38 * Added to USERS command in silcd/command_reply.c to join the client,
39 we didn't use to know about, to the channel after we've created
40 a client entry for it. Also, for clienet we did know already still
41 check whether it is on the channel or not and add it if not.
43 * Removed silc_server_command_join_notify as the function and its
46 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * Changed the client's pending command handling to the same as the
49 server's pending command handling. It is also now possible to
50 execute command reply functions from other command reply
51 function as the function callbacks for commands and command
52 replies are one and same. The pending commands are not static
53 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
54 in client connection context. Thus, pending commands are server
55 connection specific as it is convenient.
57 Changed the function silc_client_command_pending and
58 silc_client_command_pending_del and added new function
59 silc_client_command_pending_check. Removed the
60 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
63 * Added cmd_ident, current command identifier, to the client
64 connection context in lib/silcclient/client.h to keep track on
65 command identifiers used in command sending. Client's command reply
66 function handling now supports the mandatory command identifiers.
68 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
69 funtions in client to fully support pending command callbacks.
71 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
72 as one of the arguments to the application in the command reply
75 * NOTE: The FORWARDED flag is depracated. It used to be depracated
76 before first releasing SILC but came back. Now it is removed again
77 and should come back nomore. The FORWARDED flag was used only
78 by the JOINing procedure by forwarding the command packet to router.
79 Now, the JOINing procedure has been changed to more generic (due
80 to various router environment issues) and FORWARDED is not needed
81 anymore for anything. The protocol specification is yet to be
84 Now, removed silc_server_packet_forward from server and the flag
85 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
87 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
89 * Renamed NAMES command to USERS command. The NAMES was named that
90 due to historical reasons. Now it is renamed. Also, rewrote
91 parts of the USERS command. The nickname list is not sent anymore
92 by the server. Only Client ID and mode lists are sent in the USERS
93 command. Changed this also to the protocol specification.
95 The client now resolves the names and stuff after it receives
96 the USERS list from the server when joining to the channel.
98 * WHOIS and IDENTIFY commands has been changed to support multiple
99 Client ID's per command. One can now search for multiple users
100 in the network by sending only one WHOIS or IDENTIFY command.
101 Changed the code and the protocol specifications.
103 * Removed silc_server_command_identify_parse and changed that IDENTIFY
104 uses silc_server_command_whois_parse to parse the request. */
106 * If normal server, do not parse the WHOIS and IDENTIFY requests
107 before sending it to the router. Saves some time.
109 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Fixed JOIN command on client library. Wrong number of arguments
112 used to crash the client.
114 * Added silc_server_channel_has_global function to check whether
115 channel has global users or not.
117 * Added silc_server_channel_has_local function to check whether channel
118 has locally connected clients on the channel.
120 * The silc_server_remove_from_one_channel now checks whether the
121 channel has global users or not after given client was removed from
122 the channel. It also checks whether the channel has local clients
123 on the channel anymore. If it does not have then the channel entry
124 is removed as it is not needed anymore.
126 * The silc_server_notify now checks on JOIN notify whether the joining
127 client is one of locally connected or global. If it is global then
128 the channel has now global users on the channel and that is marked
129 to the channel entry. Also, it now saves the global client to
130 global list who is joining and JOINs it to the channel. This is
131 for normal server, that is.
133 Changed silc_server_send_notify_on_channel,
134 silc_server_packet_relay_to_channel and
135 silc_server_packet_send_to_channel check if we are normal server
136 and client has router set (ie. global client) do not send the
137 message to that client, as it is already routed to our router.
139 * Implemented LEAVE notify type handling in silc_server_notify
142 * Tested LEAVE command in router environment successfully. Tested
143 with two routers, two servers and two clients.
147 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
149 * Implemented SIGNOFF notify type handling in silc_server_notify
152 * silc_server_remove_id now removes the client entry from all channels
153 it has joined and thusly sends SIGNOFF notify type.
155 * Rewrote the NAMES list generation in server by removing two excess
156 loops. The lists are created now inside one loop.
158 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
160 * silc_server_remove_channel_user checks now also global list
161 for channel and client.
163 * silc_server_new_channel_user checks now both local and global
164 list for channel and client. Fixed a bug in client id decoding.
165 Used to decode wrong buffer.
167 * silc_server_channel_message checks now both local and global
168 list for channel entry.
170 * Tested channel joining (hence JOIN) in router environment
171 successfully. Tested with two routers, two servers and two
174 * Tested channel message sending in router environment successfully.
176 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Added silc_server_save_channel_key into server.[ch] to save the
179 received channel key in Channel Key payload processing. It is
180 also used in JOIN command reply handling.
182 Equivalent function silc_client_save_channel_key added into
183 client.[ch] into client library.
185 * Changed JOIN command reply to send information whether the channel
186 was created or not (is existing already) and the channel key
187 payload. Changed protocol specs accordingly.
189 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
190 the request was sent by ID and not by nickname. Crashed on
193 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
195 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
196 now correctly save the received data.
198 * silc_server_free_sock_user_data now notifies routers in the
199 network about entities leaving the network.
201 At the same time implemented functions silc_server_remove_id
202 and silc_server_send_remove_id to receive and send REMOVE_ID
203 packets. The packet is used to notify routers in the network
204 about leaving entities. The ID removed will become invalid in
207 * Added function silc_idlist_del_server into server. Removes and
208 free's server entry from ID list.
210 * silc_server_private_message function now checks, if we are router,
211 that the destination ID really is valid ID, naturally.
213 * In router when NEW_ID packet is received (for new client) the
214 hash of the Client ID is saved in the ID Cache but the
215 client->nickname is set to NULL, instead of putting the hash
218 IDENTIFY command now also checks that client->nickname must be
219 valid. If it is not if will request the data from the server who
220 owns the client. Added new function
221 silc_server_command_identify_check.
223 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
224 to set the command to already allocated Command Payload.
226 * Tested private message sending in router environment with two
227 routers, two servers and two clients. Fixed minor bugs and now
230 * Fixed segfault from client's NAMES command. Used to crash if
233 * Forwarded packets must not be routed even if it is not destined
234 to the receiver. Changed server code comply with this.
236 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
238 * Added `require_reverse_mapping' boolean value to ServerParams
239 structure. If TRUE (not default) the server will require that
240 the connecting host has fully qualified domain name.
242 If the reverse mapping is not required and hostname could not be
243 found the IP address is used as hostname.
245 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Implemented version string checking to both client and server.
248 The check is incomplete currently due to the abnormal version
249 strings used in development version of SILC.
251 * Changed all command functions in server to use the new
254 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Changed char *data to unsigned char *data in ID Cache system to
257 support binary data as ID Cache data. Changed code to support
258 binary data in lib/silccore/idcache.c.
260 * Renamed silc_server_packet_relay_command_reply to
261 silc_server_command_reply as it is normal packet receiving
262 function. Rewrote the function to accept command replys for
263 servers and not only for clients.
265 * Mark remote router always as registered server if we are connecting
266 to it. Otherwise, commands sent by the router to us are ignored.
268 * All ID List find routines now returns the ID Cache Entry pointer
269 as well if requested.
271 * WHOIS command works now in router environment, tested with two
272 routers, two servers and two clients.
274 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
275 in router environment (as it is almost equivalent to WHOIS) but
276 hasn't been tested thoroughly. Added new functions:
278 silc_server_command_identify_parse
279 silc_server_command_identify_send_reply
280 silc_server_command_identify_from_client
281 silc_server_command_identify_from_server
283 * Disabled route cache adding because adding two different ID's with
284 same IP replaces the old cache entry thus giving wrong route.
285 The entry->router->connection is always the fastest route anyway
286 so route cache may not be needed. Of course, new routes maybe
287 established after receiving the ID when the entry->router->connection
288 might not be anymore the most optimal.
290 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
292 * Add route cache for received ID for fast routing.
294 * Added silc_server_packet_route to route received packet on router
295 that is not destined to us.
297 * Renamed silc_server_get_route to silc_server_route_get.
299 * Added id_string and id_string_len fields into SilcServer to
300 include encoded ServerID for fast comparing without excess
301 encoding of the ID's.
303 * Cleaned up WHOIS command on server side. Added following static
306 silc_server_command_whois_parse
307 silc_server_command_whois_check
308 silc_server_command_whois_send_reply
309 silc_server_command_whois_from_client
310 silc_server_command_whois_from_server
312 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
313 arguments in command replies. All command functions should be
314 updated to use this macro.
316 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Minor typo fixes on command reply handling on server.
320 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Added silc_server_command_add_to_channel internal routine to add
323 the client to the channel after router has created the channel and
324 sent command reply to the server.
326 * Added generic silc_server_send_command to send any command from
329 * Use static buffer with ID rendering instead of duplicating data.
331 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Fixed a channel user mode bug when joining to a channel server gave
334 everybody channel founder rights, oops.
336 * We mark ourselves as the router of the incoming server connection
337 if we are router ourselves. This way we can check in some packet
338 sending functions whether it is locally connected server. For
339 incoming router connections we put NULL.
341 * For router sending packets locally means now always sending the
342 packet cell wide; to local clients and local servers. For normal
343 server sending packet locally means sending it to only local
346 * Fixed the JOIN command to really work in router environment. If the
347 channel is created it is always created by the router. Router is
348 also responsible of making the initial joining to the channel,
349 sending JOIN notify to the sending server and distributing
350 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
351 does not exist server doesn't do anything else but forward the
352 command to the router which performs everything.
354 * Added silc_server_send_channel_key function to send the Channel Key
357 * Added silc_server_create_channel_key to create new channel key. The
358 channel key is now re-generated everytime someone joins or leaves
359 a channel, as protocol dictates. Note: channel->key_len is the
362 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Splitted server.[ch] finally. Created now packet_send.[ch] and
365 packet_receive.[ch] to separate packet sending and receiving
366 routines. The server.[ch] now includes everything else including
367 actual packet processing (writing and reading data) and other
370 Renamed silc_server_private_message_send_internal to
371 silc_server_send_private_message. The routine is still though
372 used only to relay private messages as server does not send
373 private messages itself.
375 Renamed silc_server_new_channel to silc_server_create_new_channel
376 and added new function sicl_server_new_channel that handles the
377 incoming New Channel packet. Added also new sending function
378 silc_server_send_new_channel to send New Channel Payload.
380 * Added new function silc_server_notify to process incoming notify
381 packet to the server/router. Server may then relay the notify
382 to clients if needed.
384 * Added new function silc_server_new_channel_user to process incoming
385 New Channel User packet. Router will redistribute the packet and
386 send JOIN notify to its local clients and locally connected servers
387 if needed. Normal server will send JOIN notify to its local client
388 on same channel when received this packet. Added also corresponding
389 sending function silc_server_send_new_channel_user to sent the
392 * Added boolean route argument to send_notif_to_channel and
393 packet_send_to_channel functions to attempt to route the packet
394 if it is TRUE and send only locally if it is FALSE.
396 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * silc_server_replace_id now broadcasts the received replace ID
399 packet if it is not broadcast packet already. The router must
400 broadcast to inform other routers about changed ID.
402 * Added backpointer to server's router into SilcServer context in
403 silcd/server_internal.h.
405 * Fixed silc_server_packet_broadcast to send correct broadcast
408 * The channel key is now distributed to the local client as soon
409 as it is received from the router (in router environment) so that
410 no other packet may be sent for the channel until client has
413 * silc_server_remove_channel_user now broadcasts the received
414 Remove Channel User packet if it is not broadcast packet already.
415 The router must broadcast to inform other routers about removed
418 * Added users field into SilcPacketContext that is a reference count
419 of the context. One can increase the reference count by calling
420 silc_packet_context_dup which is now changed to just increase the
421 reference count instead of duplicating the data. The reference
422 count is decresed by calling silc_packet_context_free that will
423 free the data after the reference count hits zero.
425 For now on the packet context and everything allocated into it
426 (including the raw packet from network) must be freed by calling
427 the new silc_packet_context_free function. Added also new function
428 silc_packet_context_alloc that must be used now to allocate the
429 context. This also means that if a routine is asynchronous from
430 silc_[client/server]_packet_parse_type the packet context must
431 be duplicated by calling silc_packet_context_dup. Otherwise it
432 gets free'd after silc_[client/server]_packet_parse_type returns.
433 Also, one must remember that if packet is duplicated then its
434 reference count must be decresed by calling the free function as
435 many times as it was duplicated.
437 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
438 from both client and server.
440 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Made joining to a channel working in router environment.
444 * Cleaned up JOIN command on server side and create function
445 silc_server_command_join_channel internal routine to make the
448 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
450 * Changed silc_command_pending list to SilcDList. Also, added
451 `ident' field to SilcServerCommandPending structure to identify
452 the reply and to call correct callback.
454 Added silc_server_command_pending_check function to replace the
455 corresnponding macro. The silc_command_pending list is not
458 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
459 to set identifier to previously allocated Command Payload. It
460 is used to set identifier for command when resending Command
463 * Added silc_command_payload_encode_payload to encode Command
464 Payload buffer from SilcCommandPayload structure.
466 * Added silc_argument_payload_encode_payload to encode Argument
467 payload buffer from SilcArgumentPayload structure.
469 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Changed WHOIS command to support router connection on server side.
472 The whois request is always sent to router unless the server is
473 standalone server. After server has received the reply from the
474 router will it send the reply to the client.
476 * Added silc_server_packet_broadcast into silcd/server.[ch] to
477 broadcast received broadcast packet. The function is used only
478 by router. The broadcast packet is always sent to the router's
481 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
482 render given ID to printable string, for log files for example.
484 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Made basic router to router connections working. At least they
487 can now connect to each other but nothing really works the way
488 they are supposed - yet.
490 * Added new initiator token to RouterConnection configuration
491 file in silcd/serverconfig.[ch]. It is used to tell whether we
492 are the initiator to the remote router or whether we'll expect
493 the other end to connect.
495 * Moved registering of listener task to silc_server_init, hence
496 the server starts listenning as soon as it is run, even if it
497 does not have connections to other routers. Let's see how well
500 * Changed default connection retry timeouts for more suitable in
503 * Removed cipher and such arguments from silc_idlist_add_client
504 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
505 Added new function silc_idlist_add_data to add the keys and stuff
508 * Added SilcIDListData structure and added it to SilcClientEntry
509 and SilcServerEntry as their first field in the structure. This
510 way we can explicitly cast the ID entries to the SilcIDListData
511 structure and get common data for the entries. In past, we had
512 to first check what type of connection it is and then cast it to
513 correct ID entry type. Now, we can directly cast the opaque
514 pointer to the SilcIDListData (no matter what ID entry it actually
515 is) and get the data needed.
517 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
519 * Wow, found a bug in scheduler. The scheduler uninitialized itself
520 in some circumstances even if threre were timeout tasks, though not
521 IO tasks, but tasks anyway. Now fixed.
523 * Defined SilcServerConnection structure to hold connection specific
524 stuff about directly connected servers and routers. The definition
525 is currently in silcd/server_internal.h. I thought about having
526 a bit more important role fro this struct but for now it is used
527 only when connecting to other server (or router actually).
529 * Added connecting retry support in server when connecting to
530 router(s). The retry feature implement exponential backoff
531 algorithm. Also, added SilcServerParams structure to hold default
532 parameters for server. For now, it include these retry settings
533 and are hard coded. After server is moded to be as Silc Server
534 Library this structure will be more important.
536 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Changed client librarys channel->clients table to SilcList and
539 changed code accordingly.
541 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Changed client's channel table to SilcList and changed code
544 accordingly. Also changed SilcChannelClientEntry to include back-
545 pointer to the channel so that client entry can use that structure
546 as list as well and we have fast cross-reference to the channel.
547 This change dramatically decreased the complexity of channel
548 handling with client entry and vice versa (removed one extra
549 loop when searching for channel entry from many functions).
551 * Changed server->sim from table to SilcDList and changed code
554 * NAMES command can now be used from user interface. It will show
555 the user list on the channel, neatly.
557 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
558 Code now saves realname of the user if it becomes available.
560 * Renamed configure.in to configure.in.pre and made ./prepare
561 script to automatically add correct version string to
562 configure.in which it creates from configure.in.pre.
564 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * NAMES command reply now shows users mode with the nickname when
569 * Moved silc_client_ch[u]mode[_char] functions from
570 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
571 place sucks, they are utility functions and should be in some
574 * Fixed some unsigned int's to unsigned short's. Patch by cras.
576 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
579 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Added TRQ (efficient deque and list library) into lib/trq. This is
584 a very good list library that is currently used in the SILC. Defined
585 SilcList API over the library because I didn't like the API very
586 much. See lib/trq/silclist.h for the API and examples of how to
587 use the API. Fixed various places in the code to use the new
588 SilcList API. The SilcList is meant for lists that has a structure
589 already defined as a list. It is not suitable to add just some
590 context to the list (in TRQ, the context is the list actually).
592 So, I defined SilcDList that can be used for the purpose where
593 predefined list structure does not exit. This can be used as
594 such list. Now some context just can be added to the SilcDList.
595 Currently this list is not used in the SILC just yet, though there
596 are a lot places where this can replace dynamically allocated
597 tables and I will fix these places, later, to use SilcDList.
598 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
599 and use TRQ internally).
601 Also fixed some annoying warning messages that the original TRQ
602 code generated. Also minor changes to TRQ's Makefile.in.
604 * Added support for querying by Client ID to both WHOIS and
605 IDENTIFY commands into server, as required by the protocol.
607 * Removed method function pointers from SilcBuffer structure. They
608 weren't used to anything and just increased the context size for
609 no good reason. This change also made silc_buffer_alloc and
610 silc_buffer_free functions inline functions.
612 * Disabled command flooding detection support until it's fixed so
613 that it accepts commands in but does not execute them more than once
616 * Added silc_net_localhost(), to return local hostname, into
617 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
618 that must be initialized before calling silc_client_init.
620 * Added new function: silc_server_send_notify_on_channels to send
621 notify messages to all channels client has joined. It is assured
622 that the message is sent only once per client.
624 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
625 lib/silcutil/silcutil.[ch] as silc_format function. The new
626 function is generic and is used by server as well, not only by
627 the logging routines.
629 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
630 the provided version string was not acceptable. Added new function:
631 silc_ske_check_version into lib/silcske/silcske.h. The function
632 must be implemented by the application (client or server) and it
633 does not reside in the SKE library. The function checks the version
634 string remote end sent.
636 * Added back pointers (to opaque context and to SilcSocketConnection)
637 into SilcPacketContext structure into lib/silccore/silcpacket.h.
639 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
640 duplicate packet context structure.
642 * Changed `notify' client operation to send same arguments as client
643 receives from server except for ID's. ID's are mapped to correct
644 ID entry and that is returned. Also, if channel entry is not sent
645 by server but the notify is for channel the channel entry is sent
646 to application (otherwise application doesn't know that it is for
647 channel (library gets it from packet's Destination ID)).
649 * Added silc_client_remove_from_channels into client library to
650 remove a client from all channels it has joined to. Used when
651 received SIGNOFF notify from server. Added also new function
652 silc_client_replace_from_channels to replace old ID entry with
653 new ID entry on all channels. Used when received NICK_CHANGE
656 * Fixed ID Cache list handling in silc_idlist_get_client in
657 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
658 to get (or query) client by ID.
662 * Added connection authentication status message defined by the
663 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
664 support for these into the code in client and server side.
666 * Added generic function silc_client_send_command to send any command
667 with variable argument list. Application should use this function
668 to send commands if the command functions provided by the library
669 does not suite for the application's user interface needs.
671 * Added new `failure' client operation. Application is notified about
672 received failure packet if client is executing a protocol. In this
673 case the protocol's execution has failed.
675 * Added SKE's end notify to send the SKE_SUCCESS notify message that
676 is required by the protocol.
678 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
679 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
682 * Added status flag to SilcSKE object to indicate realtime status
685 * Application receives now exactly same command reply arguments as
686 the library receives from server. However, if ID is received the
687 corresponding ID entry is returned to the application (eg. Client
688 ID is mapped to correct SilcClientEntry entry and that is returned).
689 Changed command_reply client operation due to this change.
691 * Changed all ID's in commands and in command replys as ID Payloads.
692 Change affected both client and server side codes.
694 All ID's sent in SILC network (with execption of ID's in SILC
695 Packet header) are sent in ID Payload to support variable length
698 * Server now notifies nick changes and notifies all clients on
699 the channels about the new nickname (about the new Client ID,
702 * Implemented CMODE command to change channel modes. Supports all
703 channel modes defined by the protocol specs except ban and invite
704 lists. (Also, private channel key mode is supported but support for
705 setting private channel key in client is missing, thus, this mode
706 has no effect on client side (except that server requires that the
707 client uses private channel key and normal channel traffic does not
710 Also, invite mode works per se, but INVITE command does not work
711 yet correctly, so you can set channel as invite only channel but
712 inviting clients to the channel does not work (it is yet to be
713 thought what's the best way to do it).
715 * Added new command SILC_COMMAND_CUMODE to change user mode on the
716 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
717 Implemented CUMODE command to change user's mode on the channel.
718 Supports all modes defined by the protocol specs.
720 * Added NAMES command reply to return users modes on the channel.
722 * Removed unnecessary and slow ciphers from lib/silccrypt.
724 * Set SO_KEEPALIVE option to connection sockets by default.
726 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
728 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
729 redefined the Notify Payload into protocol specs.
731 * Added silc_id_payload_parse_id to get ID directly from raw
734 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
736 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
737 accept searching by Client ID as well.
739 * Added support for LEAVE and SIGNOFF notify types in client library.
741 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
742 to parse ID Payload from raw data.
744 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Added flags parameter into silc_ske_assemble_security_properties
747 function in lib/silcske/silcske.[ch].
749 * Changed notify client operation to fit better for notify messages
750 sent by server. The notify payload received from server is now
751 passed to the application (after parsing it to SilcNotifyPayload).
752 It is application's responsibility to retrieve the arguments
753 from the payload and show the message the way it wants. The message
754 sent by server is implementation specific.
756 * Changed public keys to comply with the protocol specification.
757 Old public keys are not supported anymore and are not compatible.
759 * Removed nickname from Channel Payload as the latest draft removed
760 it. The client must resolve the nickname from the NAMES command
761 reply received when it joined the channel.
763 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
765 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Fixed some errors in protocol specification drafts.
769 * Created lib/silccore/silcnotify.c to implement Notify Payload
770 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
771 generic payloads described by protocol specifications. The file
772 includes implementations for ID Payload and Argument Payload.
774 * Changed Command Payload implementation to use the new Argument
775 Payload. Changed command_xxxx_payload to command_payload_xxxx
776 to comply with SILC coding conventions.
778 * Added suppport for Argument Payload handling in Notify Payload
779 implementation as protocol requires it. Added the new support
780 into server and client lib as well.
782 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added support for multiple nicknames on same channel. [n] is
785 added locally to the nickname if there are more than one same
786 nicknames on the channel.
788 * Server now sends all nicknames that matched WHOIS request.
789 Client also shows the list received from server.
791 * Added TOPIC command to client side. User can now set and show
792 current topic on channel.
794 * Added MOTD command to client and server. Also, server sends the
795 motd when client connects to the server.
797 * Changed version strings to comply ISO 8601.
799 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Fixed protocol error handling in client library. It should now
802 cope even if the SKE fails for some reason.
804 * Made new protocol specification drafts for submitting to IETF.
806 * Implemented TOPIC command to server in silcd/command.c.
808 * Added two new notify types into lib/silccore/silcnotify.h:
809 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
810 notify nickname change and topic setting/change on a channel.
812 * API change of command_reply operation in client library. The
813 application gets now the status type received from server as well.
815 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Removed the function just added to lib/silcutil/silcschedule.[ch].
819 * Cras fixed and optimized the packet handling even further and
820 it should work now. Minor change to the prototype of function
821 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
823 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Added new function into lib/silcutil/silcschedule.[ch]:
826 silc_schedule_with_fd to select() a specified fd. The function
827 returns after timeout expires or data arrives or goes. The
828 function is used by packet routines to wait that all data is
829 received from network.
831 * Fixed data reading from network in lib/silccore/silcpacket.c.
832 The code now assures that all data is read from the fd and then
833 continues packet processing. This was a bug fix since the code
834 used to drop some data in some circumstances.
836 * Added new function into lib/silcclient/client.[ch]:
837 silc_client_start_key_exchange to start key exchange after
838 connection has been established to server. The code internally
839 now uses this funtion but its main purpose was to provide it
840 for applications that perform their own connecting. After
841 application has created a connection it merely calls this
842 function to start the key exchange between client and server.
843 The library takes care of everything else after that.
845 Updated also lib/silcclient/README to explain the usage of
848 * Do not send to application information that connection has
849 been established. Application gets notified it by connect
852 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Applied cras's patch to add silc_schedule_one function. The
855 function runs scheduler once and returns.
857 * Fixed the scheduler after cras messed it up. The timeout
858 handling works now as it's supposed to work.
860 * Added into lib/silccore/ silcnotify.h to include notify
861 message types support. Changed silc_server_send_notify*
862 functions, in server.[ch], to support those new notify types.
863 Added the support for the notify types into client library,
864 as well. Added new notify client operation into ops.h in
867 * Changed silc_server_packet_send_to_channel to send normal
868 packets instead of just channel message packets. The function
869 is now used to send the notify packets to channels. It is not
870 used to send channel message packets anymore, as server never
873 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
874 va_arg()s as it seems to require it nowadays. I guess, if SILC
875 is compiled with older va_arg() the new code should work anyway.
877 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Splitted core library. Core library (lib/silccore) includes
880 now only SILC protocol specific core (and common) components.
881 Created new utility library (lib/silcutil) that includes more
882 generic purpose stuff. The stuff for util library was taken
883 from the old core library. This was minor and easy split.
885 * Created SILC Client Library (lib/silcclient) that includes
886 implementation of the SILC client without user interface. This
887 was major move from silc/ directory. The code has been changed
888 so that it is transparent towards the user interface. The
889 silc/ directory includes now the same user interface as before
890 and it uses the new client library. Read lib/silcclient/README.
891 Basicly, the client library performs everything else related
892 to SILC except user interface handling. Also, configuration
893 files are considered to be part of user interface and library
894 does not handle them.
896 This change also changed a lot of structures, function naming etc.
897 Most important change was that SilcClientWindow object was
898 renamed to SilcClientConnection in the client library. Created
899 also new file lib/silcclient/ops.h. Also added new files
900 silc/local_command.[ch] and silc/client_ops.[ch].
902 All these changes were made to make it easier for user interface
903 designers to create what ever user interface for the SILC client
906 It is also expected that the server will be moved to lib
907 directory as well and SILC Server Library will be created;
908 sometimes in the future.
910 * Removed Local commands from lib/silccore/silccommand.h as
911 they are application specific and new client library does not
912 handle any of those anymore.
914 * Several functions moved to lib/silcutil/silcutilc.[ch] from
915 old client implementation in silc/.
917 * Added support for callback functions in SILC_LOG_* macros.
918 Application can now set its own callbacks that will be called
919 instead of using the default functions that will always print
920 the debug messages to stderr (or stdout). Also, debugging can
921 now be disabled by setting silc_debug to FALSE and re-enabled by
922 setting it to TRUE. Note, that logging will still work even
923 if debugging is disabled.
925 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
926 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
927 silc_log_reset_debug_callbacks.
929 * To enable debugging in silc client one must give now -d
930 option on command line.
932 * Changed silc_schedule_init to automatically allocate task queues
933 if they are not allocated before calling it.
935 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Added GMP 3.1 into math library.
939 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
942 a channel in SILC network. The packet is used by servers and
943 routers to notify other routers that user has left a channel.
944 This little feature was missing until now. Added the feature
945 to protocol specification as well.
947 Added functions: silc_server_send_remove_channel_user and
948 silc_server_remove_channel_user into server.[ch].
950 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
951 lib/silccore/silcpacket.h. However, they are not implemented
954 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
956 * Fixed joining to a channel and sending channel messages
957 between server and router. The channel message sending should
958 now work inside a cell.
960 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
962 * Fixed the private message sending between server and router.
963 The private message sending should now work inside a cell.
965 * Added silc_server_replace_id into server.[ch] to replace
966 existing ID in the SILC network.
968 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
969 and silc_idlist_replace_server_id into idlist.[ch] in server.
971 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
973 * Fixed the server to server connections. Server can again now
974 connect to router. Router to router connections probably does
977 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Added dynamic protocol registering support. Now protocols can
980 registered and unregistered on the fly. Patch by cras.
982 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added lib/contrib directory to hold routines that some platforms
985 don't have but are needed by SILC.
987 * Added getopt.c, getopt1.c and getopt.h from GNU C library
988 into lin/contrib to provide getopt() and getopt_long() for
989 those who don't have it.
991 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Added AWAY command to client. When away message is set and
994 client receives a private message packet the client automatically
995 replies to the sender with the away message.
997 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
998 bug seemed to be the cause of recent problems when compiling
1001 * Added version detection support to SKE protocol specification
1002 and added the new changes to the SKE implementation as well.
1003 There were other minor changes in the SKE protocol as well.
1005 Many changes in lib/silcske/silcske.[ch] and in
1006 lib/silcske/payload.[ch].
1008 * Added ^U functionality, clear input line. Patch from cras.
1010 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Mainly small bugfixes on core library. Fixed some debugging
1013 logging and buffer overflow in silclog.c.
1015 * Updated config.sub and config.guess on the distribution tree.
1017 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Added command lagging support in server. Client may execute
1020 commands now only once in two seconds.
1022 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Optimized packet reception. MAC computation and checking is now
1025 also more optimized. A lot previously duplicated code is now
1026 used as generic by both client and server.
1028 * Fixed key pair generation in clientutil.c
1030 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1032 * Added into lib/silccore/silcbufutil.[ch] new function;
1033 silc_buffer_realloc.
1035 * Moved generic packet sending/encryption functions to
1036 lib/silccore/silcpacket.[ch] from client and server. Some
1037 rewriting of the functions.
1039 * Moved all generic packet reception/decryption functions to
1040 lib/silccore/silcpacket.[ch] from client and server. The
1041 packet processing is now much cleaner in both client and server.
1042 These were major changes in both client and server.
1044 * Created many common functions in server to do packet sending.
1045 Previously code were duplicated a lot, this has been removed
1048 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Rewrote major parts of the ID cache system. Don't know
1051 whether it is better now or not but at least the API is more
1054 * Major rewrite on ID cache stuff on client because of the ID
1055 cache API changes. Added idlist.c to client.
1057 * Also major rewrite on ID cache stuff on server as well.
1058 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1059 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1060 in hand, instead they are all put into the ID cache system now.
1061 All server_idlist_* routines uses ID cache now instead of
1062 traversing its own lists (those lists does not exist anymore).
1063 SilcIDList though still exists. Also, SilcXXXEntry's are
1066 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Finally made the SKE implementation compliant to the protocol
1069 specification. All mp integers are now binary encoded as
1070 opposed being HEX encoded.
1072 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1075 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1076 functions: silc_[encode/decode]_pem. Also added function
1077 silc_encode_pem_file to PEM encode with newlines ('\n') for
1080 * SILC public keys are now encoded either PEM or binary. Same
1081 option is for private keys as well. By default private keys
1082 are binary encoded and public keys PEM encoded. Silly HEX
1083 encoding were removed.
1085 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1086 function to create fingerprints.
1088 * Fixed a bug in SHA1; does not change the original data anymore.
1090 * Partly implemented INFO command on client and server side.
1091 Fixed CLEAR command. Changes to SERVER command; show current
1092 server(s) when giving command without arguments. Added
1093 VERSION command to client.
1095 * Added check to server that unregistered connections cannot
1096 execute commands (unless it is specificly allowed).
1098 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Fixed screen refresh.
1102 * Fixed channel joining bug from client. On some circumstances
1103 client tried to join to a channel it had already joined.
1105 * Added public key verification process into client's protocol.c.
1106 The client now verifies the public key from user and saves
1107 it into ~./silc/serverkeys/ directory.
1109 Added into: clientutil.[ch]: silc_client_verify_server_key.
1111 * Changed SKE protocol's silc_ske_initiator_finish function
1112 to accept callback function that verifies the received public
1113 key. Removed old silc_ske_verify_public_key function.
1115 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1117 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1118 silc_pkcs_private_key[_data]_set.
1120 * Made the password and public authentication more cleaner in
1121 server's protocol.c.
1123 * Removed historic and obsolete protocol `channel_auth' from
1124 both client and server.
1126 * Removed wrong way of sending command status messages from
1127 server to client in server's command.c. The old way violated
1128 protocol specification.
1130 Changes to silccore/silccommand.[ch]: removed
1131 silc_command_encode_status_payload -> not needed anymore,
1132 changed silc_command_encode_payload_va to accept extra
1133 argument on variable argument list. The argument type must
1134 now be provided to the function. Also, added new function:
1135 silc_command_encode_reply_payload_va which is same as
1136 normal command_encode_payload_va except command status type
1137 is provided as extra argument.
1139 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Added ~./silc directory handling. The directory includes the
1142 public and private keys for the client.
1144 Added silc_client_check_silc_dir, silc_client_create_identifier
1145 and silc_client_load_keys.
1147 * Implemented SILC protocol compliant public key. Added public
1148 and private key saving to and loading from files.
1150 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1151 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1152 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1153 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1154 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
