1 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Renames NAMES command to USERS command. The NAMES was named that
4 due to historical reasons. Now it is renamed. Also, rewrote
5 parts of the USERS command. The nickname list is not sent anymore
6 by the server. Only Client ID and mode lists are sent in the USERS
7 command. Changed this also to the protocol specification.
9 The client now resolves the names and stuff after it receives
10 the USERS list from the server when joining to the channel.
12 * WHOIS and IDENTIFY commands has been changed to support multiple
13 Client ID's per command. One can now search for multiple users
14 in the network by sending only one WHOIS or IDENTIFY command.
15 Changed the code and the protocol specifications.
17 * Remove silc_server_command_identify_parse and changed that IDENTIFY
18 uses silc_server_command_whois_parse to parse the request. */
20 * If normal server, do not parse the WHOIS and IDENTIFY requests
21 before sending it to the router. Saves some time.
23 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
25 * Fixed JOIN command on client library. Wrong number of arguments
26 used to crash the client.
28 * Added silc_server_channel_has_global function to check whether
29 channel has global users or not.
31 * Added silc_server_channel_has_local function to check whether channel
32 has locally connected clients on the channel.
34 * The silc_server_remove_from_one_channel now checks whether the
35 channel has global users or not after given client was removed from
36 the channel. It also checks whether the channel has local clients
37 on the channel anymore. If it does not have then the channel entry
38 is removed as it is not needed anymore.
40 * The silc_server_notify now checks on JOIN notify whether the joining
41 client is one of locally connected or global. If it is global then
42 the channel has now global users on the channel and that is marked
43 to the channel entry. Also, it now saves the global client to
44 global list who is joining and JOINs it to the channel. This is
45 for normal server, that is.
47 Changed silc_server_send_notify_on_channel,
48 silc_server_packet_relay_to_channel and
49 silc_server_packet_send_to_channel check if we are normal server
50 and client has router set (ie. global client) do not send the
51 message to that client, as it is already routed to our router.
53 * Implemented LEAVE notify type handling in silc_server_notify
56 * Tested LEAVE command in router environment successfully. Tested
57 with two routers, two servers and two clients.
61 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
63 * Implemented SIGNOFF notify type handling in silc_server_notify
66 * silc_server_remove_id now removes the client entry from all channels
67 it has joined and thusly sends SIGNOFF notify type.
69 * Rewrote the NAMES list generation in server by removing two excess
70 loops. The lists are created now inside one loop.
72 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
74 * silc_server_remove_channel_user checks now also global list
75 for channel and client.
77 * silc_server_new_channel_user checks now both local and global
78 list for channel and client. Fixed a bug in client id decoding.
79 Used to decode wrong buffer.
81 * silc_server_channel_message checks now both local and global
82 list for channel entry.
84 * Tested channel joining (hence JOIN) in router environment
85 successfully. Tested with two routers, two servers and two
88 * Tested channel message sending in router environment successfully.
90 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Added silc_server_save_channel_key into server.[ch] to save the
93 received channel key in Channel Key payload processing. It is
94 also used in JOIN command reply handling.
96 Equivalent function silc_client_save_channel_key added into
97 client.[ch] into client library.
99 * Changed JOIN command reply to send information whether the channel
100 was created or not (is existing already) and the channel key
101 payload. Changed protocol specs accordingly.
103 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
104 the request was sent by ID and not by nickname. Crashed on
107 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
110 now correctly save the received data.
112 * silc_server_free_sock_user_data now notifies routers in the
113 network about entities leaving the network.
115 At the same time implemented functions silc_server_remove_id
116 and silc_server_send_remove_id to receive and send REMOVE_ID
117 packets. The packet is used to notify routers in the network
118 about leaving entities. The ID removed will become invalid in
121 * Added function silc_idlist_del_server into server. Removes and
122 free's server entry from ID list.
124 * silc_server_private_message function now checks, if we are router,
125 that the destination ID really is valid ID, naturally.
127 * In router when NEW_ID packet is received (for new client) the
128 hash of the Client ID is saved in the ID Cache but the
129 client->nickname is set to NULL, instead of putting the hash
132 IDENTIFY command now also checks that client->nickname must be
133 valid. If it is not if will request the data from the server who
134 owns the client. Added new function
135 silc_server_command_identify_check.
137 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
138 to set the command to already allocated Command Payload.
140 * Tested private message sending in router environment with two
141 routers, two servers and two clients. Fixed minor bugs and now
144 * Fixed segfault from client's NAMES command. Used to crash if
147 * Forwarded packets must not be routed even if it is not destined
148 to the receiver. Changed server code comply with this.
150 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
152 * Added `require_reverse_mapping' boolean value to ServerParams
153 structure. If TRUE (not default) the server will require that
154 the connecting host has fully qualified domain name.
156 If the reverse mapping is not required and hostname could not be
157 found the IP address is used as hostname.
159 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Implemented version string checking to both client and server.
162 The check is incomplete currently due to the abnormal version
163 strings used in development version of SILC.
165 * Changed all command functions in server to use the new
168 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
170 * Changed char *data to unsigned char *data in ID Cache system to
171 support binary data as ID Cache data. Changed code to support
172 binary data in lib/silccore/idcache.c.
174 * Renamed silc_server_packet_relay_command_reply to
175 silc_server_command_reply as it is normal packet receiving
176 function. Rewrote the function to accept command replys for
177 servers and not only for clients.
179 * Mark remote router always as registered server if we are connecting
180 to it. Otherwise, commands sent by the router to us are ignored.
182 * All ID List find routines now returns the ID Cache Entry pointer
183 as well if requested.
185 * WHOIS command works now in router environment, tested with two
186 routers, two servers and two clients.
188 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
189 in router environment (as it is almost equivalent to WHOIS) but
190 hasn't been tested thoroughly. Added new functions:
192 silc_server_command_identify_parse
193 silc_server_command_identify_send_reply
194 silc_server_command_identify_from_client
195 silc_server_command_identify_from_server
197 * Disabled route cache adding because adding two different ID's with
198 same IP replaces the old cache entry thus giving wrong route.
199 The entry->router->connection is always the fastest route anyway
200 so route cache may not be needed. Of course, new routes maybe
201 established after receiving the ID when the entry->router->connection
202 might not be anymore the most optimal.
204 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * Add route cache for received ID for fast routing.
208 * Added silc_server_packet_route to route received packet on router
209 that is not destined to us.
211 * Renamed silc_server_get_route to silc_server_route_get.
213 * Added id_string and id_string_len fields into SilcServer to
214 include encoded ServerID for fast comparing without excess
215 encoding of the ID's.
217 * Cleaned up WHOIS command on server side. Added following static
220 silc_server_command_whois_parse
221 silc_server_command_whois_check
222 silc_server_command_whois_send_reply
223 silc_server_command_whois_from_client
224 silc_server_command_whois_from_server
226 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
227 arguments in command replies. All command functions should be
228 updated to use this macro.
230 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
232 * Minor typo fixes on command reply handling on server.
234 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Added silc_server_command_add_to_channel internal routine to add
237 the client to the channel after router has created the channel and
238 sent command reply to the server.
240 * Added generic silc_server_send_command to send any command from
243 * Use static buffer with ID rendering instead of duplicating data.
245 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
247 * Fixed a channel user mode bug when joining to a channel server gave
248 everybody channel founder rights, oops.
250 * We mark ourselves as the router of the incoming server connection
251 if we are router ourselves. This way we can check in some packet
252 sending functions whether it is locally connected server. For
253 incoming router connections we put NULL.
255 * For router sending packets locally means now always sending the
256 packet cell wide; to local clients and local servers. For normal
257 server sending packet locally means sending it to only local
260 * Fixed the JOIN command to really work in router environment. If the
261 channel is created it is always created by the router. Router is
262 also responsible of making the initial joining to the channel,
263 sending JOIN notify to the sending server and distributing
264 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
265 does not exist server doesn't do anything else but forward the
266 command to the router which performs everything.
268 * Added silc_server_send_channel_key function to send the Channel Key
271 * Added silc_server_create_channel_key to create new channel key. The
272 channel key is now re-generated everytime someone joins or leaves
273 a channel, as protocol dictates. Note: channel->key_len is the
276 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Splitted server.[ch] finally. Created now packet_send.[ch] and
279 packet_receive.[ch] to separate packet sending and receiving
280 routines. The server.[ch] now includes everything else including
281 actual packet processing (writing and reading data) and other
284 Renamed silc_server_private_message_send_internal to
285 silc_server_send_private_message. The routine is still though
286 used only to relay private messages as server does not send
287 private messages itself.
289 Renamed silc_server_new_channel to silc_server_create_new_channel
290 and added new function sicl_server_new_channel that handles the
291 incoming New Channel packet. Added also new sending function
292 silc_server_send_new_channel to send New Channel Payload.
294 * Added new function silc_server_notify to process incoming notify
295 packet to the server/router. Server may then relay the notify
296 to clients if needed.
298 * Added new function silc_server_new_channel_user to process incoming
299 New Channel User packet. Router will redistribute the packet and
300 send JOIN notify to its local clients and locally connected servers
301 if needed. Normal server will send JOIN notify to its local client
302 on same channel when received this packet. Added also corresponding
303 sending function silc_server_send_new_channel_user to sent the
306 * Added boolean route argument to send_notif_to_channel and
307 packet_send_to_channel functions to attempt to route the packet
308 if it is TRUE and send only locally if it is FALSE.
310 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * silc_server_replace_id now broadcasts the received replace ID
313 packet if it is not broadcast packet already. The router must
314 broadcast to inform other routers about changed ID.
316 * Added backpointer to server's router into SilcServer context in
317 silcd/server_internal.h.
319 * Fixed silc_server_packet_broadcast to send correct broadcast
322 * The channel key is now distributed to the local client as soon
323 as it is received from the router (in router environment) so that
324 no other packet may be sent for the channel until client has
327 * silc_server_remove_channel_user now broadcasts the received
328 Remove Channel User packet if it is not broadcast packet already.
329 The router must broadcast to inform other routers about removed
332 * Added users field into SilcPacketContext that is a reference count
333 of the context. One can increase the reference count by calling
334 silc_packet_context_dup which is now changed to just increase the
335 reference count instead of duplicating the data. The reference
336 count is decresed by calling silc_packet_context_free that will
337 free the data after the reference count hits zero.
339 For now on the packet context and everything allocated into it
340 (including the raw packet from network) must be freed by calling
341 the new silc_packet_context_free function. Added also new function
342 silc_packet_context_alloc that must be used now to allocate the
343 context. This also means that if a routine is asynchronous from
344 silc_[client/server]_packet_parse_type the packet context must
345 be duplicated by calling silc_packet_context_dup. Otherwise it
346 gets free'd after silc_[client/server]_packet_parse_type returns.
347 Also, one must remember that if packet is duplicated then its
348 reference count must be decresed by calling the free function as
349 many times as it was duplicated.
351 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
352 from both client and server.
354 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
356 * Made joining to a channel working in router environment.
358 * Cleaned up JOIN command on server side and create function
359 silc_server_command_join_channel internal routine to make the
362 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Changed silc_command_pending list to SilcDList. Also, added
365 `ident' field to SilcServerCommandPending structure to identify
366 the reply and to call correct callback.
368 Added silc_server_command_pending_check function to replace the
369 corresnponding macro. The silc_command_pending list is not
372 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
373 to set identifier to previously allocated Command Payload. It
374 is used to set identifier for command when resending Command
377 * Added silc_command_payload_encode_payload to encode Command
378 Payload buffer from SilcCommandPayload structure.
380 * Added silc_argument_payload_encode_payload to encode Argument
381 payload buffer from SilcArgumentPayload structure.
383 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Changed WHOIS command to support router connection on server side.
386 The whois request is always sent to router unless the server is
387 standalone server. After server has received the reply from the
388 router will it send the reply to the client.
390 * Added silc_server_packet_broadcast into silcd/server.[ch] to
391 broadcast received broadcast packet. The function is used only
392 by router. The broadcast packet is always sent to the router's
395 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
396 render given ID to printable string, for log files for example.
398 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Made basic router to router connections working. At least they
401 can now connect to each other but nothing really works the way
402 they are supposed - yet.
404 * Added new initiator token to RouterConnection configuration
405 file in silcd/serverconfig.[ch]. It is used to tell whether we
406 are the initiator to the remote router or whether we'll expect
407 the other end to connect.
409 * Moved registering of listener task to silc_server_init, hence
410 the server starts listenning as soon as it is run, even if it
411 does not have connections to other routers. Let's see how well
414 * Changed default connection retry timeouts for more suitable in
417 * Removed cipher and such arguments from silc_idlist_add_client
418 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
419 Added new function silc_idlist_add_data to add the keys and stuff
422 * Added SilcIDListData structure and added it to SilcClientEntry
423 and SilcServerEntry as their first field in the structure. This
424 way we can explicitly cast the ID entries to the SilcIDListData
425 structure and get common data for the entries. In past, we had
426 to first check what type of connection it is and then cast it to
427 correct ID entry type. Now, we can directly cast the opaque
428 pointer to the SilcIDListData (no matter what ID entry it actually
429 is) and get the data needed.
431 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Wow, found a bug in scheduler. The scheduler uninitialized itself
434 in some circumstances even if threre were timeout tasks, though not
435 IO tasks, but tasks anyway. Now fixed.
437 * Defined SilcServerConnection structure to hold connection specific
438 stuff about directly connected servers and routers. The definition
439 is currently in silcd/server_internal.h. I thought about having
440 a bit more important role fro this struct but for now it is used
441 only when connecting to other server (or router actually).
443 * Added connecting retry support in server when connecting to
444 router(s). The retry feature implement exponential backoff
445 algorithm. Also, added SilcServerParams structure to hold default
446 parameters for server. For now, it include these retry settings
447 and are hard coded. After server is moded to be as Silc Server
448 Library this structure will be more important.
450 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Changed client librarys channel->clients table to SilcList and
453 changed code accordingly.
455 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
457 * Changed client's channel table to SilcList and changed code
458 accordingly. Also changed SilcChannelClientEntry to include back-
459 pointer to the channel so that client entry can use that structure
460 as list as well and we have fast cross-reference to the channel.
461 This change dramatically decreased the complexity of channel
462 handling with client entry and vice versa (removed one extra
463 loop when searching for channel entry from many functions).
465 * Changed server->sim from table to SilcDList and changed code
468 * NAMES command can now be used from user interface. It will show
469 the user list on the channel, neatly.
471 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
472 Code now saves realname of the user if it becomes available.
474 * Renamed configure.in to configure.in.pre and made ./prepare
475 script to automatically add correct version string to
476 configure.in which it creates from configure.in.pre.
478 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * NAMES command reply now shows users mode with the nickname when
483 * Moved silc_client_ch[u]mode[_char] functions from
484 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
485 place sucks, they are utility functions and should be in some
488 * Fixed some unsigned int's to unsigned short's. Patch by cras.
490 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
493 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
497 * Added TRQ (efficient deque and list library) into lib/trq. This is
498 a very good list library that is currently used in the SILC. Defined
499 SilcList API over the library because I didn't like the API very
500 much. See lib/trq/silclist.h for the API and examples of how to
501 use the API. Fixed various places in the code to use the new
502 SilcList API. The SilcList is meant for lists that has a structure
503 already defined as a list. It is not suitable to add just some
504 context to the list (in TRQ, the context is the list actually).
506 So, I defined SilcDList that can be used for the purpose where
507 predefined list structure does not exit. This can be used as
508 such list. Now some context just can be added to the SilcDList.
509 Currently this list is not used in the SILC just yet, though there
510 are a lot places where this can replace dynamically allocated
511 tables and I will fix these places, later, to use SilcDList.
512 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
513 and use TRQ internally).
515 Also fixed some annoying warning messages that the original TRQ
516 code generated. Also minor changes to TRQ's Makefile.in.
518 * Added support for querying by Client ID to both WHOIS and
519 IDENTIFY commands into server, as required by the protocol.
521 * Removed method function pointers from SilcBuffer structure. They
522 weren't used to anything and just increased the context size for
523 no good reason. This change also made silc_buffer_alloc and
524 silc_buffer_free functions inline functions.
526 * Disabled command flooding detection support until it's fixed so
527 that it accepts commands in but does not execute them more than once
530 * Added silc_net_localhost(), to return local hostname, into
531 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
532 that must be initialized before calling silc_client_init.
534 * Added new function: silc_server_send_notify_on_channels to send
535 notify messages to all channels client has joined. It is assured
536 that the message is sent only once per client.
538 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
539 lib/silcutil/silcutil.[ch] as silc_format function. The new
540 function is generic and is used by server as well, not only by
541 the logging routines.
543 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
544 the provided version string was not acceptable. Added new function:
545 silc_ske_check_version into lib/silcske/silcske.h. The function
546 must be implemented by the application (client or server) and it
547 does not reside in the SKE library. The function checks the version
548 string remote end sent.
550 * Added back pointers (to opaque context and to SilcSocketConnection)
551 into SilcPacketContext structure into lib/silccore/silcpacket.h.
553 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
554 duplicate packet context structure.
556 * Changed `notify' client operation to send same arguments as client
557 receives from server except for ID's. ID's are mapped to correct
558 ID entry and that is returned. Also, if channel entry is not sent
559 by server but the notify is for channel the channel entry is sent
560 to application (otherwise application doesn't know that it is for
561 channel (library gets it from packet's Destination ID)).
563 * Added silc_client_remove_from_channels into client library to
564 remove a client from all channels it has joined to. Used when
565 received SIGNOFF notify from server. Added also new function
566 silc_client_replace_from_channels to replace old ID entry with
567 new ID entry on all channels. Used when received NICK_CHANGE
570 * Fixed ID Cache list handling in silc_idlist_get_client in
571 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
572 to get (or query) client by ID.
576 * Added connection authentication status message defined by the
577 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
578 support for these into the code in client and server side.
580 * Added generic function silc_client_send_command to send any command
581 with variable argument list. Application should use this function
582 to send commands if the command functions provided by the library
583 does not suite for the application's user interface needs.
585 * Added new `failure' client operation. Application is notified about
586 received failure packet if client is executing a protocol. In this
587 case the protocol's execution has failed.
589 * Added SKE's end notify to send the SKE_SUCCESS notify message that
590 is required by the protocol.
592 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
593 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
596 * Added status flag to SilcSKE object to indicate realtime status
599 * Application receives now exactly same command reply arguments as
600 the library receives from server. However, if ID is received the
601 corresponding ID entry is returned to the application (eg. Client
602 ID is mapped to correct SilcClientEntry entry and that is returned).
603 Changed command_reply client operation due to this change.
605 * Changed all ID's in commands and in command replys as ID Payloads.
606 Change affected both client and server side codes.
608 All ID's sent in SILC network (with execption of ID's in SILC
609 Packet header) are sent in ID Payload to support variable length
612 * Server now notifies nick changes and notifies all clients on
613 the channels about the new nickname (about the new Client ID,
616 * Implemented CMODE command to change channel modes. Supports all
617 channel modes defined by the protocol specs except ban and invite
618 lists. (Also, private channel key mode is supported but support for
619 setting private channel key in client is missing, thus, this mode
620 has no effect on client side (except that server requires that the
621 client uses private channel key and normal channel traffic does not
624 Also, invite mode works per se, but INVITE command does not work
625 yet correctly, so you can set channel as invite only channel but
626 inviting clients to the channel does not work (it is yet to be
627 thought what's the best way to do it).
629 * Added new command SILC_COMMAND_CUMODE to change user mode on the
630 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
631 Implemented CUMODE command to change user's mode on the channel.
632 Supports all modes defined by the protocol specs.
634 * Added NAMES command reply to return users modes on the channel.
636 * Removed unnecessary and slow ciphers from lib/silccrypt.
638 * Set SO_KEEPALIVE option to connection sockets by default.
640 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
642 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
643 redefined the Notify Payload into protocol specs.
645 * Added silc_id_payload_parse_id to get ID directly from raw
648 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
651 accept searching by Client ID as well.
653 * Added support for LEAVE and SIGNOFF notify types in client library.
655 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
656 to parse ID Payload from raw data.
658 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Added flags parameter into silc_ske_assemble_security_properties
661 function in lib/silcske/silcske.[ch].
663 * Changed notify client operation to fit better for notify messages
664 sent by server. The notify payload received from server is now
665 passed to the application (after parsing it to SilcNotifyPayload).
666 It is application's responsibility to retrieve the arguments
667 from the payload and show the message the way it wants. The message
668 sent by server is implementation specific.
670 * Changed public keys to comply with the protocol specification.
671 Old public keys are not supported anymore and are not compatible.
673 * Removed nickname from Channel Payload as the latest draft removed
674 it. The client must resolve the nickname from the NAMES command
675 reply received when it joined the channel.
677 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
679 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Fixed some errors in protocol specification drafts.
683 * Created lib/silccore/silcnotify.c to implement Notify Payload
684 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
685 generic payloads described by protocol specifications. The file
686 includes implementations for ID Payload and Argument Payload.
688 * Changed Command Payload implementation to use the new Argument
689 Payload. Changed command_xxxx_payload to command_payload_xxxx
690 to comply with SILC coding conventions.
692 * Added suppport for Argument Payload handling in Notify Payload
693 implementation as protocol requires it. Added the new support
694 into server and client lib as well.
696 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Added support for multiple nicknames on same channel. [n] is
699 added locally to the nickname if there are more than one same
700 nicknames on the channel.
702 * Server now sends all nicknames that matched WHOIS request.
703 Client also shows the list received from server.
705 * Added TOPIC command to client side. User can now set and show
706 current topic on channel.
708 * Added MOTD command to client and server. Also, server sends the
709 motd when client connects to the server.
711 * Changed version strings to comply ISO 8601.
713 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * Fixed protocol error handling in client library. It should now
716 cope even if the SKE fails for some reason.
718 * Made new protocol specification drafts for submitting to IETF.
720 * Implemented TOPIC command to server in silcd/command.c.
722 * Added two new notify types into lib/silccore/silcnotify.h:
723 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
724 notify nickname change and topic setting/change on a channel.
726 * API change of command_reply operation in client library. The
727 application gets now the status type received from server as well.
729 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Removed the function just added to lib/silcutil/silcschedule.[ch].
733 * Cras fixed and optimized the packet handling even further and
734 it should work now. Minor change to the prototype of function
735 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
737 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Added new function into lib/silcutil/silcschedule.[ch]:
740 silc_schedule_with_fd to select() a specified fd. The function
741 returns after timeout expires or data arrives or goes. The
742 function is used by packet routines to wait that all data is
743 received from network.
745 * Fixed data reading from network in lib/silccore/silcpacket.c.
746 The code now assures that all data is read from the fd and then
747 continues packet processing. This was a bug fix since the code
748 used to drop some data in some circumstances.
750 * Added new function into lib/silcclient/client.[ch]:
751 silc_client_start_key_exchange to start key exchange after
752 connection has been established to server. The code internally
753 now uses this funtion but its main purpose was to provide it
754 for applications that perform their own connecting. After
755 application has created a connection it merely calls this
756 function to start the key exchange between client and server.
757 The library takes care of everything else after that.
759 Updated also lib/silcclient/README to explain the usage of
762 * Do not send to application information that connection has
763 been established. Application gets notified it by connect
766 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
768 * Applied cras's patch to add silc_schedule_one function. The
769 function runs scheduler once and returns.
771 * Fixed the scheduler after cras messed it up. The timeout
772 handling works now as it's supposed to work.
774 * Added into lib/silccore/ silcnotify.h to include notify
775 message types support. Changed silc_server_send_notify*
776 functions, in server.[ch], to support those new notify types.
777 Added the support for the notify types into client library,
778 as well. Added new notify client operation into ops.h in
781 * Changed silc_server_packet_send_to_channel to send normal
782 packets instead of just channel message packets. The function
783 is now used to send the notify packets to channels. It is not
784 used to send channel message packets anymore, as server never
787 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
788 va_arg()s as it seems to require it nowadays. I guess, if SILC
789 is compiled with older va_arg() the new code should work anyway.
791 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Splitted core library. Core library (lib/silccore) includes
794 now only SILC protocol specific core (and common) components.
795 Created new utility library (lib/silcutil) that includes more
796 generic purpose stuff. The stuff for util library was taken
797 from the old core library. This was minor and easy split.
799 * Created SILC Client Library (lib/silcclient) that includes
800 implementation of the SILC client without user interface. This
801 was major move from silc/ directory. The code has been changed
802 so that it is transparent towards the user interface. The
803 silc/ directory includes now the same user interface as before
804 and it uses the new client library. Read lib/silcclient/README.
805 Basicly, the client library performs everything else related
806 to SILC except user interface handling. Also, configuration
807 files are considered to be part of user interface and library
808 does not handle them.
810 This change also changed a lot of structures, function naming etc.
811 Most important change was that SilcClientWindow object was
812 renamed to SilcClientConnection in the client library. Created
813 also new file lib/silcclient/ops.h. Also added new files
814 silc/local_command.[ch] and silc/client_ops.[ch].
816 All these changes were made to make it easier for user interface
817 designers to create what ever user interface for the SILC client
820 It is also expected that the server will be moved to lib
821 directory as well and SILC Server Library will be created;
822 sometimes in the future.
824 * Removed Local commands from lib/silccore/silccommand.h as
825 they are application specific and new client library does not
826 handle any of those anymore.
828 * Several functions moved to lib/silcutil/silcutilc.[ch] from
829 old client implementation in silc/.
831 * Added support for callback functions in SILC_LOG_* macros.
832 Application can now set its own callbacks that will be called
833 instead of using the default functions that will always print
834 the debug messages to stderr (or stdout). Also, debugging can
835 now be disabled by setting silc_debug to FALSE and re-enabled by
836 setting it to TRUE. Note, that logging will still work even
837 if debugging is disabled.
839 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
840 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
841 silc_log_reset_debug_callbacks.
843 * To enable debugging in silc client one must give now -d
844 option on command line.
846 * Changed silc_schedule_init to automatically allocate task queues
847 if they are not allocated before calling it.
849 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Added GMP 3.1 into math library.
853 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
856 a channel in SILC network. The packet is used by servers and
857 routers to notify other routers that user has left a channel.
858 This little feature was missing until now. Added the feature
859 to protocol specification as well.
861 Added functions: silc_server_send_remove_channel_user and
862 silc_server_remove_channel_user into server.[ch].
864 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
865 lib/silccore/silcpacket.h. However, they are not implemented
868 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
870 * Fixed joining to a channel and sending channel messages
871 between server and router. The channel message sending should
872 now work inside a cell.
874 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Fixed the private message sending between server and router.
877 The private message sending should now work inside a cell.
879 * Added silc_server_replace_id into server.[ch] to replace
880 existing ID in the SILC network.
882 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
883 and silc_idlist_replace_server_id into idlist.[ch] in server.
885 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Fixed the server to server connections. Server can again now
888 connect to router. Router to router connections probably does
891 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Added dynamic protocol registering support. Now protocols can
894 registered and unregistered on the fly. Patch by cras.
896 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Added lib/contrib directory to hold routines that some platforms
899 don't have but are needed by SILC.
901 * Added getopt.c, getopt1.c and getopt.h from GNU C library
902 into lin/contrib to provide getopt() and getopt_long() for
903 those who don't have it.
905 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
907 * Added AWAY command to client. When away message is set and
908 client receives a private message packet the client automatically
909 replies to the sender with the away message.
911 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
912 bug seemed to be the cause of recent problems when compiling
915 * Added version detection support to SKE protocol specification
916 and added the new changes to the SKE implementation as well.
917 There were other minor changes in the SKE protocol as well.
919 Many changes in lib/silcske/silcske.[ch] and in
920 lib/silcske/payload.[ch].
922 * Added ^U functionality, clear input line. Patch from cras.
924 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Mainly small bugfixes on core library. Fixed some debugging
927 logging and buffer overflow in silclog.c.
929 * Updated config.sub and config.guess on the distribution tree.
931 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Added command lagging support in server. Client may execute
934 commands now only once in two seconds.
936 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
938 * Optimized packet reception. MAC computation and checking is now
939 also more optimized. A lot previously duplicated code is now
940 used as generic by both client and server.
942 * Fixed key pair generation in clientutil.c
944 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
946 * Added into lib/silccore/silcbufutil.[ch] new function;
949 * Moved generic packet sending/encryption functions to
950 lib/silccore/silcpacket.[ch] from client and server. Some
951 rewriting of the functions.
953 * Moved all generic packet reception/decryption functions to
954 lib/silccore/silcpacket.[ch] from client and server. The
955 packet processing is now much cleaner in both client and server.
956 These were major changes in both client and server.
958 * Created many common functions in server to do packet sending.
959 Previously code were duplicated a lot, this has been removed
962 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Rewrote major parts of the ID cache system. Don't know
965 whether it is better now or not but at least the API is more
968 * Major rewrite on ID cache stuff on client because of the ID
969 cache API changes. Added idlist.c to client.
971 * Also major rewrite on ID cache stuff on server as well.
972 Major rewrite of idlist.[ch]. SilcXXXList's are now named
973 SilcXXXEntry's. We won't keep anymore idlist specific pointers
974 in hand, instead they are all put into the ID cache system now.
975 All server_idlist_* routines uses ID cache now instead of
976 traversing its own lists (those lists does not exist anymore).
977 SilcIDList though still exists. Also, SilcXXXEntry's are
980 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
982 * Finally made the SKE implementation compliant to the protocol
983 specification. All mp integers are now binary encoded as
984 opposed being HEX encoded.
986 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
989 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
990 functions: silc_[encode/decode]_pem. Also added function
991 silc_encode_pem_file to PEM encode with newlines ('\n') for
994 * SILC public keys are now encoded either PEM or binary. Same
995 option is for private keys as well. By default private keys
996 are binary encoded and public keys PEM encoded. Silly HEX
997 encoding were removed.
999 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1000 function to create fingerprints.
1002 * Fixed a bug in SHA1; does not change the original data anymore.
1004 * Partly implemented INFO command on client and server side.
1005 Fixed CLEAR command. Changes to SERVER command; show current
1006 server(s) when giving command without arguments. Added
1007 VERSION command to client.
1009 * Added check to server that unregistered connections cannot
1010 execute commands (unless it is specificly allowed).
1012 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1014 * Fixed screen refresh.
1016 * Fixed channel joining bug from client. On some circumstances
1017 client tried to join to a channel it had already joined.
1019 * Added public key verification process into client's protocol.c.
1020 The client now verifies the public key from user and saves
1021 it into ~./silc/serverkeys/ directory.
1023 Added into: clientutil.[ch]: silc_client_verify_server_key.
1025 * Changed SKE protocol's silc_ske_initiator_finish function
1026 to accept callback function that verifies the received public
1027 key. Removed old silc_ske_verify_public_key function.
1029 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1032 silc_pkcs_private_key[_data]_set.
1034 * Made the password and public authentication more cleaner in
1035 server's protocol.c.
1037 * Removed historic and obsolete protocol `channel_auth' from
1038 both client and server.
1040 * Removed wrong way of sending command status messages from
1041 server to client in server's command.c. The old way violated
1042 protocol specification.
1044 Changes to silccore/silccommand.[ch]: removed
1045 silc_command_encode_status_payload -> not needed anymore,
1046 changed silc_command_encode_payload_va to accept extra
1047 argument on variable argument list. The argument type must
1048 now be provided to the function. Also, added new function:
1049 silc_command_encode_reply_payload_va which is same as
1050 normal command_encode_payload_va except command status type
1051 is provided as extra argument.
1053 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Added ~./silc directory handling. The directory includes the
1056 public and private keys for the client.
1058 Added silc_client_check_silc_dir, silc_client_create_identifier
1059 and silc_client_load_keys.
1061 * Implemented SILC protocol compliant public key. Added public
1062 and private key saving to and loading from files.
1064 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1065 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1066 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1067 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1068 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1070 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1071 silc_pkcs_load_[public/private]_key.
1073 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Added silc_server_get_route (route.[ch]) to get connection
1076 data for the fastest route for given ID.
1078 * Implemented INVITE command on client and server. The command
1079 were re-defined in the SILC Protocol Specification and the
1080 implementation now complies with the specification.
1082 * Implemented PING command on client and server.
1084 * Implemented NAMES command on client and server. The server side
1085 supports currently only normal server not router server yet.
1086 Some changes to NAMES definition in SILC protocol specification.
1088 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1090 * Implemented LEAVE command on client and server.
1092 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1093 again. This change was made to the protocol as well. Server
1094 should not violate the protocol specification anymore.
1096 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1098 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1099 was tested. SOCKS4 was not but should work anyway.
