1 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Changed the client's pending command handling to the same as the
4 server's pending command handling. It is also now possible to
5 execute command reply functions from other command reply
6 function as the function callbacks for commands and command
7 replies are one and same. The pending commands are not static
8 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
9 in client connection context. Thus, pending commands are server
10 connection specific as it is convenient.
12 Changed the function silc_client_command_pending and
13 silc_client_command_pending_del and added new function
14 silc_client_command_pending_check. Removed the
15 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
18 * Added cmd_ident, current command identifier, to the client
19 connection context in lib/silcclient/client.h to keep track on
20 command identifiers used in command sending. Client's command reply
21 function handling now supports the mandatory command identifiers.
23 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
24 funtions in client to fully support pending command callbacks.
26 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
27 as one of the arguments to the application in the command reply
30 * NOTE: The FORWARDED flag is depracated. It used to be depracated
31 before first releasing SILC but came back. Now it is removed again
32 and should come back nomore. The FORWARDED flag was used only
33 by the JOINing procedure by forwarding the command packet to router.
34 Now, the JOINing procedure has been changed to more generic (due
35 to various router environment issues) and FORWARDED is not needed
36 anymore for anything. The protocol specification is yet to be
39 Now, removed silc_server_packet_forward from server and the flag
40 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
42 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Renamed NAMES command to USERS command. The NAMES was named that
45 due to historical reasons. Now it is renamed. Also, rewrote
46 parts of the USERS command. The nickname list is not sent anymore
47 by the server. Only Client ID and mode lists are sent in the USERS
48 command. Changed this also to the protocol specification.
50 The client now resolves the names and stuff after it receives
51 the USERS list from the server when joining to the channel.
53 * WHOIS and IDENTIFY commands has been changed to support multiple
54 Client ID's per command. One can now search for multiple users
55 in the network by sending only one WHOIS or IDENTIFY command.
56 Changed the code and the protocol specifications.
58 * Removed silc_server_command_identify_parse and changed that IDENTIFY
59 uses silc_server_command_whois_parse to parse the request. */
61 * If normal server, do not parse the WHOIS and IDENTIFY requests
62 before sending it to the router. Saves some time.
64 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
66 * Fixed JOIN command on client library. Wrong number of arguments
67 used to crash the client.
69 * Added silc_server_channel_has_global function to check whether
70 channel has global users or not.
72 * Added silc_server_channel_has_local function to check whether channel
73 has locally connected clients on the channel.
75 * The silc_server_remove_from_one_channel now checks whether the
76 channel has global users or not after given client was removed from
77 the channel. It also checks whether the channel has local clients
78 on the channel anymore. If it does not have then the channel entry
79 is removed as it is not needed anymore.
81 * The silc_server_notify now checks on JOIN notify whether the joining
82 client is one of locally connected or global. If it is global then
83 the channel has now global users on the channel and that is marked
84 to the channel entry. Also, it now saves the global client to
85 global list who is joining and JOINs it to the channel. This is
86 for normal server, that is.
88 Changed silc_server_send_notify_on_channel,
89 silc_server_packet_relay_to_channel and
90 silc_server_packet_send_to_channel check if we are normal server
91 and client has router set (ie. global client) do not send the
92 message to that client, as it is already routed to our router.
94 * Implemented LEAVE notify type handling in silc_server_notify
97 * Tested LEAVE command in router environment successfully. Tested
98 with two routers, two servers and two clients.
102 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
104 * Implemented SIGNOFF notify type handling in silc_server_notify
107 * silc_server_remove_id now removes the client entry from all channels
108 it has joined and thusly sends SIGNOFF notify type.
110 * Rewrote the NAMES list generation in server by removing two excess
111 loops. The lists are created now inside one loop.
113 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * silc_server_remove_channel_user checks now also global list
116 for channel and client.
118 * silc_server_new_channel_user checks now both local and global
119 list for channel and client. Fixed a bug in client id decoding.
120 Used to decode wrong buffer.
122 * silc_server_channel_message checks now both local and global
123 list for channel entry.
125 * Tested channel joining (hence JOIN) in router environment
126 successfully. Tested with two routers, two servers and two
129 * Tested channel message sending in router environment successfully.
131 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Added silc_server_save_channel_key into server.[ch] to save the
134 received channel key in Channel Key payload processing. It is
135 also used in JOIN command reply handling.
137 Equivalent function silc_client_save_channel_key added into
138 client.[ch] into client library.
140 * Changed JOIN command reply to send information whether the channel
141 was created or not (is existing already) and the channel key
142 payload. Changed protocol specs accordingly.
144 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
145 the request was sent by ID and not by nickname. Crashed on
148 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
151 now correctly save the received data.
153 * silc_server_free_sock_user_data now notifies routers in the
154 network about entities leaving the network.
156 At the same time implemented functions silc_server_remove_id
157 and silc_server_send_remove_id to receive and send REMOVE_ID
158 packets. The packet is used to notify routers in the network
159 about leaving entities. The ID removed will become invalid in
162 * Added function silc_idlist_del_server into server. Removes and
163 free's server entry from ID list.
165 * silc_server_private_message function now checks, if we are router,
166 that the destination ID really is valid ID, naturally.
168 * In router when NEW_ID packet is received (for new client) the
169 hash of the Client ID is saved in the ID Cache but the
170 client->nickname is set to NULL, instead of putting the hash
173 IDENTIFY command now also checks that client->nickname must be
174 valid. If it is not if will request the data from the server who
175 owns the client. Added new function
176 silc_server_command_identify_check.
178 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
179 to set the command to already allocated Command Payload.
181 * Tested private message sending in router environment with two
182 routers, two servers and two clients. Fixed minor bugs and now
185 * Fixed segfault from client's NAMES command. Used to crash if
188 * Forwarded packets must not be routed even if it is not destined
189 to the receiver. Changed server code comply with this.
191 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Added `require_reverse_mapping' boolean value to ServerParams
194 structure. If TRUE (not default) the server will require that
195 the connecting host has fully qualified domain name.
197 If the reverse mapping is not required and hostname could not be
198 found the IP address is used as hostname.
200 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
202 * Implemented version string checking to both client and server.
203 The check is incomplete currently due to the abnormal version
204 strings used in development version of SILC.
206 * Changed all command functions in server to use the new
209 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Changed char *data to unsigned char *data in ID Cache system to
212 support binary data as ID Cache data. Changed code to support
213 binary data in lib/silccore/idcache.c.
215 * Renamed silc_server_packet_relay_command_reply to
216 silc_server_command_reply as it is normal packet receiving
217 function. Rewrote the function to accept command replys for
218 servers and not only for clients.
220 * Mark remote router always as registered server if we are connecting
221 to it. Otherwise, commands sent by the router to us are ignored.
223 * All ID List find routines now returns the ID Cache Entry pointer
224 as well if requested.
226 * WHOIS command works now in router environment, tested with two
227 routers, two servers and two clients.
229 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
230 in router environment (as it is almost equivalent to WHOIS) but
231 hasn't been tested thoroughly. Added new functions:
233 silc_server_command_identify_parse
234 silc_server_command_identify_send_reply
235 silc_server_command_identify_from_client
236 silc_server_command_identify_from_server
238 * Disabled route cache adding because adding two different ID's with
239 same IP replaces the old cache entry thus giving wrong route.
240 The entry->router->connection is always the fastest route anyway
241 so route cache may not be needed. Of course, new routes maybe
242 established after receiving the ID when the entry->router->connection
243 might not be anymore the most optimal.
245 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Add route cache for received ID for fast routing.
249 * Added silc_server_packet_route to route received packet on router
250 that is not destined to us.
252 * Renamed silc_server_get_route to silc_server_route_get.
254 * Added id_string and id_string_len fields into SilcServer to
255 include encoded ServerID for fast comparing without excess
256 encoding of the ID's.
258 * Cleaned up WHOIS command on server side. Added following static
261 silc_server_command_whois_parse
262 silc_server_command_whois_check
263 silc_server_command_whois_send_reply
264 silc_server_command_whois_from_client
265 silc_server_command_whois_from_server
267 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
268 arguments in command replies. All command functions should be
269 updated to use this macro.
271 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
273 * Minor typo fixes on command reply handling on server.
275 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * Added silc_server_command_add_to_channel internal routine to add
278 the client to the channel after router has created the channel and
279 sent command reply to the server.
281 * Added generic silc_server_send_command to send any command from
284 * Use static buffer with ID rendering instead of duplicating data.
286 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Fixed a channel user mode bug when joining to a channel server gave
289 everybody channel founder rights, oops.
291 * We mark ourselves as the router of the incoming server connection
292 if we are router ourselves. This way we can check in some packet
293 sending functions whether it is locally connected server. For
294 incoming router connections we put NULL.
296 * For router sending packets locally means now always sending the
297 packet cell wide; to local clients and local servers. For normal
298 server sending packet locally means sending it to only local
301 * Fixed the JOIN command to really work in router environment. If the
302 channel is created it is always created by the router. Router is
303 also responsible of making the initial joining to the channel,
304 sending JOIN notify to the sending server and distributing
305 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
306 does not exist server doesn't do anything else but forward the
307 command to the router which performs everything.
309 * Added silc_server_send_channel_key function to send the Channel Key
312 * Added silc_server_create_channel_key to create new channel key. The
313 channel key is now re-generated everytime someone joins or leaves
314 a channel, as protocol dictates. Note: channel->key_len is the
317 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
319 * Splitted server.[ch] finally. Created now packet_send.[ch] and
320 packet_receive.[ch] to separate packet sending and receiving
321 routines. The server.[ch] now includes everything else including
322 actual packet processing (writing and reading data) and other
325 Renamed silc_server_private_message_send_internal to
326 silc_server_send_private_message. The routine is still though
327 used only to relay private messages as server does not send
328 private messages itself.
330 Renamed silc_server_new_channel to silc_server_create_new_channel
331 and added new function sicl_server_new_channel that handles the
332 incoming New Channel packet. Added also new sending function
333 silc_server_send_new_channel to send New Channel Payload.
335 * Added new function silc_server_notify to process incoming notify
336 packet to the server/router. Server may then relay the notify
337 to clients if needed.
339 * Added new function silc_server_new_channel_user to process incoming
340 New Channel User packet. Router will redistribute the packet and
341 send JOIN notify to its local clients and locally connected servers
342 if needed. Normal server will send JOIN notify to its local client
343 on same channel when received this packet. Added also corresponding
344 sending function silc_server_send_new_channel_user to sent the
347 * Added boolean route argument to send_notif_to_channel and
348 packet_send_to_channel functions to attempt to route the packet
349 if it is TRUE and send only locally if it is FALSE.
351 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * silc_server_replace_id now broadcasts the received replace ID
354 packet if it is not broadcast packet already. The router must
355 broadcast to inform other routers about changed ID.
357 * Added backpointer to server's router into SilcServer context in
358 silcd/server_internal.h.
360 * Fixed silc_server_packet_broadcast to send correct broadcast
363 * The channel key is now distributed to the local client as soon
364 as it is received from the router (in router environment) so that
365 no other packet may be sent for the channel until client has
368 * silc_server_remove_channel_user now broadcasts the received
369 Remove Channel User packet if it is not broadcast packet already.
370 The router must broadcast to inform other routers about removed
373 * Added users field into SilcPacketContext that is a reference count
374 of the context. One can increase the reference count by calling
375 silc_packet_context_dup which is now changed to just increase the
376 reference count instead of duplicating the data. The reference
377 count is decresed by calling silc_packet_context_free that will
378 free the data after the reference count hits zero.
380 For now on the packet context and everything allocated into it
381 (including the raw packet from network) must be freed by calling
382 the new silc_packet_context_free function. Added also new function
383 silc_packet_context_alloc that must be used now to allocate the
384 context. This also means that if a routine is asynchronous from
385 silc_[client/server]_packet_parse_type the packet context must
386 be duplicated by calling silc_packet_context_dup. Otherwise it
387 gets free'd after silc_[client/server]_packet_parse_type returns.
388 Also, one must remember that if packet is duplicated then its
389 reference count must be decresed by calling the free function as
390 many times as it was duplicated.
392 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
393 from both client and server.
395 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Made joining to a channel working in router environment.
399 * Cleaned up JOIN command on server side and create function
400 silc_server_command_join_channel internal routine to make the
403 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
405 * Changed silc_command_pending list to SilcDList. Also, added
406 `ident' field to SilcServerCommandPending structure to identify
407 the reply and to call correct callback.
409 Added silc_server_command_pending_check function to replace the
410 corresnponding macro. The silc_command_pending list is not
413 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
414 to set identifier to previously allocated Command Payload. It
415 is used to set identifier for command when resending Command
418 * Added silc_command_payload_encode_payload to encode Command
419 Payload buffer from SilcCommandPayload structure.
421 * Added silc_argument_payload_encode_payload to encode Argument
422 payload buffer from SilcArgumentPayload structure.
424 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
426 * Changed WHOIS command to support router connection on server side.
427 The whois request is always sent to router unless the server is
428 standalone server. After server has received the reply from the
429 router will it send the reply to the client.
431 * Added silc_server_packet_broadcast into silcd/server.[ch] to
432 broadcast received broadcast packet. The function is used only
433 by router. The broadcast packet is always sent to the router's
436 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
437 render given ID to printable string, for log files for example.
439 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
441 * Made basic router to router connections working. At least they
442 can now connect to each other but nothing really works the way
443 they are supposed - yet.
445 * Added new initiator token to RouterConnection configuration
446 file in silcd/serverconfig.[ch]. It is used to tell whether we
447 are the initiator to the remote router or whether we'll expect
448 the other end to connect.
450 * Moved registering of listener task to silc_server_init, hence
451 the server starts listenning as soon as it is run, even if it
452 does not have connections to other routers. Let's see how well
455 * Changed default connection retry timeouts for more suitable in
458 * Removed cipher and such arguments from silc_idlist_add_client
459 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
460 Added new function silc_idlist_add_data to add the keys and stuff
463 * Added SilcIDListData structure and added it to SilcClientEntry
464 and SilcServerEntry as their first field in the structure. This
465 way we can explicitly cast the ID entries to the SilcIDListData
466 structure and get common data for the entries. In past, we had
467 to first check what type of connection it is and then cast it to
468 correct ID entry type. Now, we can directly cast the opaque
469 pointer to the SilcIDListData (no matter what ID entry it actually
470 is) and get the data needed.
472 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
474 * Wow, found a bug in scheduler. The scheduler uninitialized itself
475 in some circumstances even if threre were timeout tasks, though not
476 IO tasks, but tasks anyway. Now fixed.
478 * Defined SilcServerConnection structure to hold connection specific
479 stuff about directly connected servers and routers. The definition
480 is currently in silcd/server_internal.h. I thought about having
481 a bit more important role fro this struct but for now it is used
482 only when connecting to other server (or router actually).
484 * Added connecting retry support in server when connecting to
485 router(s). The retry feature implement exponential backoff
486 algorithm. Also, added SilcServerParams structure to hold default
487 parameters for server. For now, it include these retry settings
488 and are hard coded. After server is moded to be as Silc Server
489 Library this structure will be more important.
491 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Changed client librarys channel->clients table to SilcList and
494 changed code accordingly.
496 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Changed client's channel table to SilcList and changed code
499 accordingly. Also changed SilcChannelClientEntry to include back-
500 pointer to the channel so that client entry can use that structure
501 as list as well and we have fast cross-reference to the channel.
502 This change dramatically decreased the complexity of channel
503 handling with client entry and vice versa (removed one extra
504 loop when searching for channel entry from many functions).
506 * Changed server->sim from table to SilcDList and changed code
509 * NAMES command can now be used from user interface. It will show
510 the user list on the channel, neatly.
512 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
513 Code now saves realname of the user if it becomes available.
515 * Renamed configure.in to configure.in.pre and made ./prepare
516 script to automatically add correct version string to
517 configure.in which it creates from configure.in.pre.
519 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * NAMES command reply now shows users mode with the nickname when
524 * Moved silc_client_ch[u]mode[_char] functions from
525 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
526 place sucks, they are utility functions and should be in some
529 * Fixed some unsigned int's to unsigned short's. Patch by cras.
531 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
534 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
538 * Added TRQ (efficient deque and list library) into lib/trq. This is
539 a very good list library that is currently used in the SILC. Defined
540 SilcList API over the library because I didn't like the API very
541 much. See lib/trq/silclist.h for the API and examples of how to
542 use the API. Fixed various places in the code to use the new
543 SilcList API. The SilcList is meant for lists that has a structure
544 already defined as a list. It is not suitable to add just some
545 context to the list (in TRQ, the context is the list actually).
547 So, I defined SilcDList that can be used for the purpose where
548 predefined list structure does not exit. This can be used as
549 such list. Now some context just can be added to the SilcDList.
550 Currently this list is not used in the SILC just yet, though there
551 are a lot places where this can replace dynamically allocated
552 tables and I will fix these places, later, to use SilcDList.
553 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
554 and use TRQ internally).
556 Also fixed some annoying warning messages that the original TRQ
557 code generated. Also minor changes to TRQ's Makefile.in.
559 * Added support for querying by Client ID to both WHOIS and
560 IDENTIFY commands into server, as required by the protocol.
562 * Removed method function pointers from SilcBuffer structure. They
563 weren't used to anything and just increased the context size for
564 no good reason. This change also made silc_buffer_alloc and
565 silc_buffer_free functions inline functions.
567 * Disabled command flooding detection support until it's fixed so
568 that it accepts commands in but does not execute them more than once
571 * Added silc_net_localhost(), to return local hostname, into
572 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
573 that must be initialized before calling silc_client_init.
575 * Added new function: silc_server_send_notify_on_channels to send
576 notify messages to all channels client has joined. It is assured
577 that the message is sent only once per client.
579 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
580 lib/silcutil/silcutil.[ch] as silc_format function. The new
581 function is generic and is used by server as well, not only by
582 the logging routines.
584 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
585 the provided version string was not acceptable. Added new function:
586 silc_ske_check_version into lib/silcske/silcske.h. The function
587 must be implemented by the application (client or server) and it
588 does not reside in the SKE library. The function checks the version
589 string remote end sent.
591 * Added back pointers (to opaque context and to SilcSocketConnection)
592 into SilcPacketContext structure into lib/silccore/silcpacket.h.
594 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
595 duplicate packet context structure.
597 * Changed `notify' client operation to send same arguments as client
598 receives from server except for ID's. ID's are mapped to correct
599 ID entry and that is returned. Also, if channel entry is not sent
600 by server but the notify is for channel the channel entry is sent
601 to application (otherwise application doesn't know that it is for
602 channel (library gets it from packet's Destination ID)).
604 * Added silc_client_remove_from_channels into client library to
605 remove a client from all channels it has joined to. Used when
606 received SIGNOFF notify from server. Added also new function
607 silc_client_replace_from_channels to replace old ID entry with
608 new ID entry on all channels. Used when received NICK_CHANGE
611 * Fixed ID Cache list handling in silc_idlist_get_client in
612 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
613 to get (or query) client by ID.
617 * Added connection authentication status message defined by the
618 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
619 support for these into the code in client and server side.
621 * Added generic function silc_client_send_command to send any command
622 with variable argument list. Application should use this function
623 to send commands if the command functions provided by the library
624 does not suite for the application's user interface needs.
626 * Added new `failure' client operation. Application is notified about
627 received failure packet if client is executing a protocol. In this
628 case the protocol's execution has failed.
630 * Added SKE's end notify to send the SKE_SUCCESS notify message that
631 is required by the protocol.
633 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
634 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
637 * Added status flag to SilcSKE object to indicate realtime status
640 * Application receives now exactly same command reply arguments as
641 the library receives from server. However, if ID is received the
642 corresponding ID entry is returned to the application (eg. Client
643 ID is mapped to correct SilcClientEntry entry and that is returned).
644 Changed command_reply client operation due to this change.
646 * Changed all ID's in commands and in command replys as ID Payloads.
647 Change affected both client and server side codes.
649 All ID's sent in SILC network (with execption of ID's in SILC
650 Packet header) are sent in ID Payload to support variable length
653 * Server now notifies nick changes and notifies all clients on
654 the channels about the new nickname (about the new Client ID,
657 * Implemented CMODE command to change channel modes. Supports all
658 channel modes defined by the protocol specs except ban and invite
659 lists. (Also, private channel key mode is supported but support for
660 setting private channel key in client is missing, thus, this mode
661 has no effect on client side (except that server requires that the
662 client uses private channel key and normal channel traffic does not
665 Also, invite mode works per se, but INVITE command does not work
666 yet correctly, so you can set channel as invite only channel but
667 inviting clients to the channel does not work (it is yet to be
668 thought what's the best way to do it).
670 * Added new command SILC_COMMAND_CUMODE to change user mode on the
671 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
672 Implemented CUMODE command to change user's mode on the channel.
673 Supports all modes defined by the protocol specs.
675 * Added NAMES command reply to return users modes on the channel.
677 * Removed unnecessary and slow ciphers from lib/silccrypt.
679 * Set SO_KEEPALIVE option to connection sockets by default.
681 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
683 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
684 redefined the Notify Payload into protocol specs.
686 * Added silc_id_payload_parse_id to get ID directly from raw
689 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
692 accept searching by Client ID as well.
694 * Added support for LEAVE and SIGNOFF notify types in client library.
696 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
697 to parse ID Payload from raw data.
699 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Added flags parameter into silc_ske_assemble_security_properties
702 function in lib/silcske/silcske.[ch].
704 * Changed notify client operation to fit better for notify messages
705 sent by server. The notify payload received from server is now
706 passed to the application (after parsing it to SilcNotifyPayload).
707 It is application's responsibility to retrieve the arguments
708 from the payload and show the message the way it wants. The message
709 sent by server is implementation specific.
711 * Changed public keys to comply with the protocol specification.
712 Old public keys are not supported anymore and are not compatible.
714 * Removed nickname from Channel Payload as the latest draft removed
715 it. The client must resolve the nickname from the NAMES command
716 reply received when it joined the channel.
718 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
720 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Fixed some errors in protocol specification drafts.
724 * Created lib/silccore/silcnotify.c to implement Notify Payload
725 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
726 generic payloads described by protocol specifications. The file
727 includes implementations for ID Payload and Argument Payload.
729 * Changed Command Payload implementation to use the new Argument
730 Payload. Changed command_xxxx_payload to command_payload_xxxx
731 to comply with SILC coding conventions.
733 * Added suppport for Argument Payload handling in Notify Payload
734 implementation as protocol requires it. Added the new support
735 into server and client lib as well.
737 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Added support for multiple nicknames on same channel. [n] is
740 added locally to the nickname if there are more than one same
741 nicknames on the channel.
743 * Server now sends all nicknames that matched WHOIS request.
744 Client also shows the list received from server.
746 * Added TOPIC command to client side. User can now set and show
747 current topic on channel.
749 * Added MOTD command to client and server. Also, server sends the
750 motd when client connects to the server.
752 * Changed version strings to comply ISO 8601.
754 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Fixed protocol error handling in client library. It should now
757 cope even if the SKE fails for some reason.
759 * Made new protocol specification drafts for submitting to IETF.
761 * Implemented TOPIC command to server in silcd/command.c.
763 * Added two new notify types into lib/silccore/silcnotify.h:
764 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
765 notify nickname change and topic setting/change on a channel.
767 * API change of command_reply operation in client library. The
768 application gets now the status type received from server as well.
770 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
772 * Removed the function just added to lib/silcutil/silcschedule.[ch].
774 * Cras fixed and optimized the packet handling even further and
775 it should work now. Minor change to the prototype of function
776 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
778 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Added new function into lib/silcutil/silcschedule.[ch]:
781 silc_schedule_with_fd to select() a specified fd. The function
782 returns after timeout expires or data arrives or goes. The
783 function is used by packet routines to wait that all data is
784 received from network.
786 * Fixed data reading from network in lib/silccore/silcpacket.c.
787 The code now assures that all data is read from the fd and then
788 continues packet processing. This was a bug fix since the code
789 used to drop some data in some circumstances.
791 * Added new function into lib/silcclient/client.[ch]:
792 silc_client_start_key_exchange to start key exchange after
793 connection has been established to server. The code internally
794 now uses this funtion but its main purpose was to provide it
795 for applications that perform their own connecting. After
796 application has created a connection it merely calls this
797 function to start the key exchange between client and server.
798 The library takes care of everything else after that.
800 Updated also lib/silcclient/README to explain the usage of
803 * Do not send to application information that connection has
804 been established. Application gets notified it by connect
807 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Applied cras's patch to add silc_schedule_one function. The
810 function runs scheduler once and returns.
812 * Fixed the scheduler after cras messed it up. The timeout
813 handling works now as it's supposed to work.
815 * Added into lib/silccore/ silcnotify.h to include notify
816 message types support. Changed silc_server_send_notify*
817 functions, in server.[ch], to support those new notify types.
818 Added the support for the notify types into client library,
819 as well. Added new notify client operation into ops.h in
822 * Changed silc_server_packet_send_to_channel to send normal
823 packets instead of just channel message packets. The function
824 is now used to send the notify packets to channels. It is not
825 used to send channel message packets anymore, as server never
828 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
829 va_arg()s as it seems to require it nowadays. I guess, if SILC
830 is compiled with older va_arg() the new code should work anyway.
832 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Splitted core library. Core library (lib/silccore) includes
835 now only SILC protocol specific core (and common) components.
836 Created new utility library (lib/silcutil) that includes more
837 generic purpose stuff. The stuff for util library was taken
838 from the old core library. This was minor and easy split.
840 * Created SILC Client Library (lib/silcclient) that includes
841 implementation of the SILC client without user interface. This
842 was major move from silc/ directory. The code has been changed
843 so that it is transparent towards the user interface. The
844 silc/ directory includes now the same user interface as before
845 and it uses the new client library. Read lib/silcclient/README.
846 Basicly, the client library performs everything else related
847 to SILC except user interface handling. Also, configuration
848 files are considered to be part of user interface and library
849 does not handle them.
851 This change also changed a lot of structures, function naming etc.
852 Most important change was that SilcClientWindow object was
853 renamed to SilcClientConnection in the client library. Created
854 also new file lib/silcclient/ops.h. Also added new files
855 silc/local_command.[ch] and silc/client_ops.[ch].
857 All these changes were made to make it easier for user interface
858 designers to create what ever user interface for the SILC client
861 It is also expected that the server will be moved to lib
862 directory as well and SILC Server Library will be created;
863 sometimes in the future.
865 * Removed Local commands from lib/silccore/silccommand.h as
866 they are application specific and new client library does not
867 handle any of those anymore.
869 * Several functions moved to lib/silcutil/silcutilc.[ch] from
870 old client implementation in silc/.
872 * Added support for callback functions in SILC_LOG_* macros.
873 Application can now set its own callbacks that will be called
874 instead of using the default functions that will always print
875 the debug messages to stderr (or stdout). Also, debugging can
876 now be disabled by setting silc_debug to FALSE and re-enabled by
877 setting it to TRUE. Note, that logging will still work even
878 if debugging is disabled.
880 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
881 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
882 silc_log_reset_debug_callbacks.
884 * To enable debugging in silc client one must give now -d
885 option on command line.
887 * Changed silc_schedule_init to automatically allocate task queues
888 if they are not allocated before calling it.
890 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * Added GMP 3.1 into math library.
894 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
897 a channel in SILC network. The packet is used by servers and
898 routers to notify other routers that user has left a channel.
899 This little feature was missing until now. Added the feature
900 to protocol specification as well.
902 Added functions: silc_server_send_remove_channel_user and
903 silc_server_remove_channel_user into server.[ch].
905 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
906 lib/silccore/silcpacket.h. However, they are not implemented
909 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * Fixed joining to a channel and sending channel messages
912 between server and router. The channel message sending should
913 now work inside a cell.
915 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Fixed the private message sending between server and router.
918 The private message sending should now work inside a cell.
920 * Added silc_server_replace_id into server.[ch] to replace
921 existing ID in the SILC network.
923 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
924 and silc_idlist_replace_server_id into idlist.[ch] in server.
926 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
928 * Fixed the server to server connections. Server can again now
929 connect to router. Router to router connections probably does
932 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
934 * Added dynamic protocol registering support. Now protocols can
935 registered and unregistered on the fly. Patch by cras.
937 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
939 * Added lib/contrib directory to hold routines that some platforms
940 don't have but are needed by SILC.
942 * Added getopt.c, getopt1.c and getopt.h from GNU C library
943 into lin/contrib to provide getopt() and getopt_long() for
944 those who don't have it.
946 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Added AWAY command to client. When away message is set and
949 client receives a private message packet the client automatically
950 replies to the sender with the away message.
952 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
953 bug seemed to be the cause of recent problems when compiling
956 * Added version detection support to SKE protocol specification
957 and added the new changes to the SKE implementation as well.
958 There were other minor changes in the SKE protocol as well.
960 Many changes in lib/silcske/silcske.[ch] and in
961 lib/silcske/payload.[ch].
963 * Added ^U functionality, clear input line. Patch from cras.
965 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Mainly small bugfixes on core library. Fixed some debugging
968 logging and buffer overflow in silclog.c.
970 * Updated config.sub and config.guess on the distribution tree.
972 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Added command lagging support in server. Client may execute
975 commands now only once in two seconds.
977 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Optimized packet reception. MAC computation and checking is now
980 also more optimized. A lot previously duplicated code is now
981 used as generic by both client and server.
983 * Fixed key pair generation in clientutil.c
985 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added into lib/silccore/silcbufutil.[ch] new function;
990 * Moved generic packet sending/encryption functions to
991 lib/silccore/silcpacket.[ch] from client and server. Some
992 rewriting of the functions.
994 * Moved all generic packet reception/decryption functions to
995 lib/silccore/silcpacket.[ch] from client and server. The
996 packet processing is now much cleaner in both client and server.
997 These were major changes in both client and server.
999 * Created many common functions in server to do packet sending.
1000 Previously code were duplicated a lot, this has been removed
1003 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1005 * Rewrote major parts of the ID cache system. Don't know
1006 whether it is better now or not but at least the API is more
1009 * Major rewrite on ID cache stuff on client because of the ID
1010 cache API changes. Added idlist.c to client.
1012 * Also major rewrite on ID cache stuff on server as well.
1013 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1014 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1015 in hand, instead they are all put into the ID cache system now.
1016 All server_idlist_* routines uses ID cache now instead of
1017 traversing its own lists (those lists does not exist anymore).
1018 SilcIDList though still exists. Also, SilcXXXEntry's are
1021 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Finally made the SKE implementation compliant to the protocol
1024 specification. All mp integers are now binary encoded as
1025 opposed being HEX encoded.
1027 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1030 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1031 functions: silc_[encode/decode]_pem. Also added function
1032 silc_encode_pem_file to PEM encode with newlines ('\n') for
1035 * SILC public keys are now encoded either PEM or binary. Same
1036 option is for private keys as well. By default private keys
1037 are binary encoded and public keys PEM encoded. Silly HEX
1038 encoding were removed.
1040 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1041 function to create fingerprints.
1043 * Fixed a bug in SHA1; does not change the original data anymore.
1045 * Partly implemented INFO command on client and server side.
1046 Fixed CLEAR command. Changes to SERVER command; show current
1047 server(s) when giving command without arguments. Added
1048 VERSION command to client.
1050 * Added check to server that unregistered connections cannot
1051 execute commands (unless it is specificly allowed).
1053 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Fixed screen refresh.
1057 * Fixed channel joining bug from client. On some circumstances
1058 client tried to join to a channel it had already joined.
1060 * Added public key verification process into client's protocol.c.
1061 The client now verifies the public key from user and saves
1062 it into ~./silc/serverkeys/ directory.
1064 Added into: clientutil.[ch]: silc_client_verify_server_key.
1066 * Changed SKE protocol's silc_ske_initiator_finish function
1067 to accept callback function that verifies the received public
1068 key. Removed old silc_ske_verify_public_key function.
1070 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1072 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1073 silc_pkcs_private_key[_data]_set.
1075 * Made the password and public authentication more cleaner in
1076 server's protocol.c.
1078 * Removed historic and obsolete protocol `channel_auth' from
1079 both client and server.
1081 * Removed wrong way of sending command status messages from
1082 server to client in server's command.c. The old way violated
1083 protocol specification.
1085 Changes to silccore/silccommand.[ch]: removed
1086 silc_command_encode_status_payload -> not needed anymore,
1087 changed silc_command_encode_payload_va to accept extra
1088 argument on variable argument list. The argument type must
1089 now be provided to the function. Also, added new function:
1090 silc_command_encode_reply_payload_va which is same as
1091 normal command_encode_payload_va except command status type
1092 is provided as extra argument.
1094 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Added ~./silc directory handling. The directory includes the
1097 public and private keys for the client.
1099 Added silc_client_check_silc_dir, silc_client_create_identifier
1100 and silc_client_load_keys.
1102 * Implemented SILC protocol compliant public key. Added public
1103 and private key saving to and loading from files.
1105 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1106 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1107 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1108 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1109 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1111 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1112 silc_pkcs_load_[public/private]_key.
1114 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1116 * Added silc_server_get_route (route.[ch]) to get connection
1117 data for the fastest route for given ID.
1119 * Implemented INVITE command on client and server. The command
1120 were re-defined in the SILC Protocol Specification and the
1121 implementation now complies with the specification.
1123 * Implemented PING command on client and server.
1125 * Implemented NAMES command on client and server. The server side
1126 supports currently only normal server not router server yet.
1127 Some changes to NAMES definition in SILC protocol specification.
1129 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1131 * Implemented LEAVE command on client and server.
1133 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1134 again. This change was made to the protocol as well. Server
1135 should not violate the protocol specification anymore.
1137 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1140 was tested. SOCKS4 was not but should work anyway.
