3 * Fixed JOIN command on client library. Wrong number of arguments
4 used to crash the client.
6 * Added silc_server_channel_has_global function to check whether
7 channel has global users or not.
9 * Added silc_server_channel_has_local function to check whether channel
10 has locally connected clients on the channel.
12 * The silc_server_remove_from_one_channel now checks whether the
13 channel has global users or not after given client was removed from
14 the channel. It also checks whether the channel has local clients
15 on the channel anymore. If it does not have then the channel entry
16 is removed as it is not needed anymore.
18 * The silc_server_notify now checks on JOIN notify whether the joining
19 client is one of locally connected or global. If it is global then
20 the channel has now global users on the channel and that is marked
21 to the channel entry. Also, it now saves the global client to
22 global list who is joining and JOINs it to the channel. This is
23 for normal server, that is.
25 Changed silc_server_send_notify_on_channel,
26 silc_server_packet_relay_to_channel and
27 silc_server_packet_send_to_channel check if we are normal server
28 and client has router set (ie. global client) do not send the
29 message to that client, as it is already routed to our router.
31 * Implemented LEAVE notify type handling in silc_server_notify
34 * Tested LEAVE command in router environment successfully. Tested
35 with two routers, two servers and two clients.
39 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
41 * Implemented SIGNOFF notify type handling in silc_server_notify
44 * silc_server_remove_id now removes the client entry from all channels
45 it has joined and thusly sends SIGNOFF notify type.
47 * Rewrote the NAMES list generation in server by removing two excess
48 loops. The lists are created now inside one loop.
50 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * silc_server_remove_channel_user checks now also global list
53 for channel and client.
55 * silc_server_new_channel_user checks now both local and global
56 list for channel and client. Fixed a bug in client id decoding.
57 Used to decode wrong buffer.
59 * silc_server_channel_message checks now both local and global
60 list for channel entry.
62 * Tested channel joining (hence JOIN) in router environment
63 successfully. Tested with two routers, two servers and two
66 * Tested channel message sending in router environment successfully.
68 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Added silc_server_save_channel_key into server.[ch] to save the
71 received channel key in Channel Key payload processing. It is
72 also used in JOIN command reply handling.
74 Equivalent function silc_client_save_channel_key added into
75 client.[ch] into client library.
77 * Changed JOIN command reply to send information whether the channel
78 was created or not (is existing already) and the channel key
79 payload. Changed protocol specs accordingly.
81 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
82 the request was sent by ID and not by nickname. Crashed on
85 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
88 now correctly save the received data.
90 * silc_server_free_sock_user_data now notifies routers in the
91 network about entities leaving the network.
93 At the same time implemented functions silc_server_remove_id
94 and silc_server_send_remove_id to receive and send REMOVE_ID
95 packets. The packet is used to notify routers in the network
96 about leaving entities. The ID removed will become invalid in
99 * Added function silc_idlist_del_server into server. Removes and
100 free's server entry from ID list.
102 * silc_server_private_message function now checks, if we are router,
103 that the destination ID really is valid ID, naturally.
105 * In router when NEW_ID packet is received (for new client) the
106 hash of the Client ID is saved in the ID Cache but the
107 client->nickname is set to NULL, instead of putting the hash
110 IDENTIFY command now also checks that client->nickname must be
111 valid. If it is not if will request the data from the server who
112 owns the client. Added new function
113 silc_server_command_identify_check.
115 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
116 to set the command to already allocated Command Payload.
118 * Tested private message sending in router environment with two
119 routers, two servers and two clients. Fixed minor bugs and now
122 * Fixed segfault from client's NAMES command. Used to crash if
125 * Forwarded packets must not be routed even if it is not destined
126 to the receiver. Changed server code comply with this.
128 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Added `require_reverse_mapping' boolean value to ServerParams
131 structure. If TRUE (not default) the server will require that
132 the connecting host has fully qualified domain name.
134 If the reverse mapping is not required and hostname could not be
135 found the IP address is used as hostname.
137 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Implemented version string checking to both client and server.
140 The check is incomplete currently due to the abnormal version
141 strings used in development version of SILC.
143 * Changed all command functions in server to use the new
146 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Changed char *data to unsigned char *data in ID Cache system to
149 support binary data as ID Cache data. Changed code to support
150 binary data in lib/silccore/idcache.c.
152 * Renamed silc_server_packet_relay_command_reply to
153 silc_server_command_reply as it is normal packet receiving
154 function. Rewrote the function to accept command replys for
155 servers and not only for clients.
157 * Mark remote router always as registered server if we are connecting
158 to it. Otherwise, commands sent by the router to us are ignored.
160 * All ID List find routines now returns the ID Cache Entry pointer
161 as well if requested.
163 * WHOIS command works now in router environment, tested with two
164 routers, two servers and two clients.
166 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
167 in router environment (as it is almost equivalent to WHOIS) but
168 hasn't been tested thoroughly. Added new functions:
170 silc_server_command_identify_parse
171 silc_server_command_identify_send_reply
172 silc_server_command_identify_from_client
173 silc_server_command_identify_from_server
175 * Disabled route cache adding because adding two different ID's with
176 same IP replaces the old cache entry thus giving wrong route.
177 The entry->router->connection is always the fastest route anyway
178 so route cache may not be needed. Of course, new routes maybe
179 established after receiving the ID when the entry->router->connection
180 might not be anymore the most optimal.
182 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Add route cache for received ID for fast routing.
186 * Added silc_server_packet_route to route received packet on router
187 that is not destined to us.
189 * Renamed silc_server_get_route to silc_server_route_get.
191 * Added id_string and id_string_len fields into SilcServer to
192 include encoded ServerID for fast comparing without excess
193 encoding of the ID's.
195 * Cleaned up WHOIS command on server side. Added following static
198 silc_server_command_whois_parse
199 silc_server_command_whois_check
200 silc_server_command_whois_send_reply
201 silc_server_command_whois_from_client
202 silc_server_command_whois_from_server
204 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
205 arguments in command replies. All command functions should be
206 updated to use this macro.
208 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
210 * Minor typo fixes on command reply handling on server.
212 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Added silc_server_command_add_to_channel internal routine to add
215 the client to the channel after router has created the channel and
216 sent command reply to the server.
218 * Added generic silc_server_send_command to send any command from
221 * Use static buffer with ID rendering instead of duplicating data.
223 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Fixed a channel user mode bug when joining to a channel server gave
226 everybody channel founder rights, oops.
228 * We mark ourselves as the router of the incoming server connection
229 if we are router ourselves. This way we can check in some packet
230 sending functions whether it is locally connected server. For
231 incoming router connections we put NULL.
233 * For router sending packets locally means now always sending the
234 packet cell wide; to local clients and local servers. For normal
235 server sending packet locally means sending it to only local
238 * Fixed the JOIN command to really work in router environment. If the
239 channel is created it is always created by the router. Router is
240 also responsible of making the initial joining to the channel,
241 sending JOIN notify to the sending server and distributing
242 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
243 does not exist server doesn't do anything else but forward the
244 command to the router which performs everything.
246 * Added silc_server_send_channel_key function to send the Channel Key
249 * Added silc_server_create_channel_key to create new channel key. The
250 channel key is now re-generated everytime someone joins or leaves
251 a channel, as protocol dictates. Note: channel->key_len is the
254 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Splitted server.[ch] finally. Created now packet_send.[ch] and
257 packet_receive.[ch] to separate packet sending and receiving
258 routines. The server.[ch] now includes everything else including
259 actual packet processing (writing and reading data) and other
262 Renamed silc_server_private_message_send_internal to
263 silc_server_send_private_message. The routine is still though
264 used only to relay private messages as server does not send
265 private messages itself.
267 Renamed silc_server_new_channel to silc_server_create_new_channel
268 and added new function sicl_server_new_channel that handles the
269 incoming New Channel packet. Added also new sending function
270 silc_server_send_new_channel to send New Channel Payload.
272 * Added new function silc_server_notify to process incoming notify
273 packet to the server/router. Server may then relay the notify
274 to clients if needed.
276 * Added new function silc_server_new_channel_user to process incoming
277 New Channel User packet. Router will redistribute the packet and
278 send JOIN notify to its local clients and locally connected servers
279 if needed. Normal server will send JOIN notify to its local client
280 on same channel when received this packet. Added also corresponding
281 sending function silc_server_send_new_channel_user to sent the
284 * Added boolean route argument to send_notif_to_channel and
285 packet_send_to_channel functions to attempt to route the packet
286 if it is TRUE and send only locally if it is FALSE.
288 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * silc_server_replace_id now broadcasts the received replace ID
291 packet if it is not broadcast packet already. The router must
292 broadcast to inform other routers about changed ID.
294 * Added backpointer to server's router into SilcServer context in
295 silcd/server_internal.h.
297 * Fixed silc_server_packet_broadcast to send correct broadcast
300 * The channel key is now distributed to the local client as soon
301 as it is received from the router (in router environment) so that
302 no other packet may be sent for the channel until client has
305 * silc_server_remove_channel_user now broadcasts the received
306 Remove Channel User packet if it is not broadcast packet already.
307 The router must broadcast to inform other routers about removed
310 * Added users field into SilcPacketContext that is a reference count
311 of the context. One can increase the reference count by calling
312 silc_packet_context_dup which is now changed to just increase the
313 reference count instead of duplicating the data. The reference
314 count is decresed by calling silc_packet_context_free that will
315 free the data after the reference count hits zero.
317 For now on the packet context and everything allocated into it
318 (including the raw packet from network) must be freed by calling
319 the new silc_packet_context_free function. Added also new function
320 silc_packet_context_alloc that must be used now to allocate the
321 context. This also means that if a routine is asynchronous from
322 silc_[client/server]_packet_parse_type the packet context must
323 be duplicated by calling silc_packet_context_dup. Otherwise it
324 gets free'd after silc_[client/server]_packet_parse_type returns.
325 Also, one must remember that if packet is duplicated then its
326 reference count must be decresed by calling the free function as
327 many times as it was duplicated.
329 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
330 from both client and server.
332 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Made joining to a channel working in router environment.
336 * Cleaned up JOIN command on server side and create function
337 silc_server_command_join_channel internal routine to make the
340 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Changed silc_command_pending list to SilcDList. Also, added
343 `ident' field to SilcServerCommandPending structure to identify
344 the reply and to call correct callback.
346 Added silc_server_command_pending_check function to replace the
347 corresnponding macro. The silc_command_pending list is not
350 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
351 to set identifier to previously allocated Command Payload. It
352 is used to set identifier for command when resending Command
355 * Added silc_command_payload_encode_payload to encode Command
356 Payload buffer from SilcCommandPayload structure.
358 * Added silc_argument_payload_encode_payload to encode Argument
359 payload buffer from SilcArgumentPayload structure.
361 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Changed WHOIS command to support router connection on server side.
364 The whois request is always sent to router unless the server is
365 standalone server. After server has received the reply from the
366 router will it send the reply to the client.
368 * Added silc_server_packet_broadcast into silcd/server.[ch] to
369 broadcast received broadcast packet. The function is used only
370 by router. The broadcast packet is always sent to the router's
373 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
374 render given ID to printable string, for log files for example.
376 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
378 * Made basic router to router connections working. At least they
379 can now connect to each other but nothing really works the way
380 they are supposed - yet.
382 * Added new initiator token to RouterConnection configuration
383 file in silcd/serverconfig.[ch]. It is used to tell whether we
384 are the initiator to the remote router or whether we'll expect
385 the other end to connect.
387 * Moved registering of listener task to silc_server_init, hence
388 the server starts listenning as soon as it is run, even if it
389 does not have connections to other routers. Let's see how well
392 * Changed default connection retry timeouts for more suitable in
395 * Removed cipher and such arguments from silc_idlist_add_client
396 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
397 Added new function silc_idlist_add_data to add the keys and stuff
400 * Added SilcIDListData structure and added it to SilcClientEntry
401 and SilcServerEntry as their first field in the structure. This
402 way we can explicitly cast the ID entries to the SilcIDListData
403 structure and get common data for the entries. In past, we had
404 to first check what type of connection it is and then cast it to
405 correct ID entry type. Now, we can directly cast the opaque
406 pointer to the SilcIDListData (no matter what ID entry it actually
407 is) and get the data needed.
409 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Wow, found a bug in scheduler. The scheduler uninitialized itself
412 in some circumstances even if threre were timeout tasks, though not
413 IO tasks, but tasks anyway. Now fixed.
415 * Defined SilcServerConnection structure to hold connection specific
416 stuff about directly connected servers and routers. The definition
417 is currently in silcd/server_internal.h. I thought about having
418 a bit more important role fro this struct but for now it is used
419 only when connecting to other server (or router actually).
421 * Added connecting retry support in server when connecting to
422 router(s). The retry feature implement exponential backoff
423 algorithm. Also, added SilcServerParams structure to hold default
424 parameters for server. For now, it include these retry settings
425 and are hard coded. After server is moded to be as Silc Server
426 Library this structure will be more important.
428 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Changed client librarys channel->clients table to SilcList and
431 changed code accordingly.
433 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Changed client's channel table to SilcList and changed code
436 accordingly. Also changed SilcChannelClientEntry to include back-
437 pointer to the channel so that client entry can use that structure
438 as list as well and we have fast cross-reference to the channel.
439 This change dramatically decreased the complexity of channel
440 handling with client entry and vice versa (removed one extra
441 loop when searching for channel entry from many functions).
443 * Changed server->sim from table to SilcDList and changed code
446 * NAMES command can now be used from user interface. It will show
447 the user list on the channel, neatly.
449 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
450 Code now saves realname of the user if it becomes available.
452 * Renamed configure.in to configure.in.pre and made ./prepare
453 script to automatically add correct version string to
454 configure.in which it creates from configure.in.pre.
456 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * NAMES command reply now shows users mode with the nickname when
461 * Moved silc_client_ch[u]mode[_char] functions from
462 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
463 place sucks, they are utility functions and should be in some
466 * Fixed some unsigned int's to unsigned short's. Patch by cras.
468 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
471 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Added TRQ (efficient deque and list library) into lib/trq. This is
476 a very good list library that is currently used in the SILC. Defined
477 SilcList API over the library because I didn't like the API very
478 much. See lib/trq/silclist.h for the API and examples of how to
479 use the API. Fixed various places in the code to use the new
480 SilcList API. The SilcList is meant for lists that has a structure
481 already defined as a list. It is not suitable to add just some
482 context to the list (in TRQ, the context is the list actually).
484 So, I defined SilcDList that can be used for the purpose where
485 predefined list structure does not exit. This can be used as
486 such list. Now some context just can be added to the SilcDList.
487 Currently this list is not used in the SILC just yet, though there
488 are a lot places where this can replace dynamically allocated
489 tables and I will fix these places, later, to use SilcDList.
490 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
491 and use TRQ internally).
493 Also fixed some annoying warning messages that the original TRQ
494 code generated. Also minor changes to TRQ's Makefile.in.
496 * Added support for querying by Client ID to both WHOIS and
497 IDENTIFY commands into server, as required by the protocol.
499 * Removed method function pointers from SilcBuffer structure. They
500 weren't used to anything and just increased the context size for
501 no good reason. This change also made silc_buffer_alloc and
502 silc_buffer_free functions inline functions.
504 * Disabled command flooding detection support until it's fixed so
505 that it accepts commands in but does not execute them more than once
508 * Added silc_net_localhost(), to return local hostname, into
509 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
510 that must be initialized before calling silc_client_init.
512 * Added new function: silc_server_send_notify_on_channels to send
513 notify messages to all channels client has joined. It is assured
514 that the message is sent only once per client.
516 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
517 lib/silcutil/silcutil.[ch] as silc_format function. The new
518 function is generic and is used by server as well, not only by
519 the logging routines.
521 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
522 the provided version string was not acceptable. Added new function:
523 silc_ske_check_version into lib/silcske/silcske.h. The function
524 must be implemented by the application (client or server) and it
525 does not reside in the SKE library. The function checks the version
526 string remote end sent.
528 * Added back pointers (to opaque context and to SilcSocketConnection)
529 into SilcPacketContext structure into lib/silccore/silcpacket.h.
531 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
532 duplicate packet context structure.
534 * Changed `notify' client operation to send same arguments as client
535 receives from server except for ID's. ID's are mapped to correct
536 ID entry and that is returned. Also, if channel entry is not sent
537 by server but the notify is for channel the channel entry is sent
538 to application (otherwise application doesn't know that it is for
539 channel (library gets it from packet's Destination ID)).
541 * Added silc_client_remove_from_channels into client library to
542 remove a client from all channels it has joined to. Used when
543 received SIGNOFF notify from server. Added also new function
544 silc_client_replace_from_channels to replace old ID entry with
545 new ID entry on all channels. Used when received NICK_CHANGE
548 * Fixed ID Cache list handling in silc_idlist_get_client in
549 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
550 to get (or query) client by ID.
554 * Added connection authentication status message defined by the
555 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
556 support for these into the code in client and server side.
558 * Added generic function silc_client_send_command to send any command
559 with variable argument list. Application should use this function
560 to send commands if the command functions provided by the library
561 does not suite for the application's user interface needs.
563 * Added new `failure' client operation. Application is notified about
564 received failure packet if client is executing a protocol. In this
565 case the protocol's execution has failed.
567 * Added SKE's end notify to send the SKE_SUCCESS notify message that
568 is required by the protocol.
570 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
571 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
574 * Added status flag to SilcSKE object to indicate realtime status
577 * Application receives now exactly same command reply arguments as
578 the library receives from server. However, if ID is received the
579 corresponding ID entry is returned to the application (eg. Client
580 ID is mapped to correct SilcClientEntry entry and that is returned).
581 Changed command_reply client operation due to this change.
583 * Changed all ID's in commands and in command replys as ID Payloads.
584 Change affected both client and server side codes.
586 All ID's sent in SILC network (with execption of ID's in SILC
587 Packet header) are sent in ID Payload to support variable length
590 * Server now notifies nick changes and notifies all clients on
591 the channels about the new nickname (about the new Client ID,
594 * Implemented CMODE command to change channel modes. Supports all
595 channel modes defined by the protocol specs except ban and invite
596 lists. (Also, private channel key mode is supported but support for
597 setting private channel key in client is missing, thus, this mode
598 has no effect on client side (except that server requires that the
599 client uses private channel key and normal channel traffic does not
602 Also, invite mode works per se, but INVITE command does not work
603 yet correctly, so you can set channel as invite only channel but
604 inviting clients to the channel does not work (it is yet to be
605 thought what's the best way to do it).
607 * Added new command SILC_COMMAND_CUMODE to change user mode on the
608 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
609 Implemented CUMODE command to change user's mode on the channel.
610 Supports all modes defined by the protocol specs.
612 * Added NAMES command reply to return users modes on the channel.
614 * Removed unnecessary and slow ciphers from lib/silccrypt.
616 * Set SO_KEEPALIVE option to connection sockets by default.
618 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
620 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
621 redefined the Notify Payload into protocol specs.
623 * Added silc_id_payload_parse_id to get ID directly from raw
626 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
629 accept searching by Client ID as well.
631 * Added support for LEAVE and SIGNOFF notify types in client library.
633 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
634 to parse ID Payload from raw data.
636 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
638 * Added flags parameter into silc_ske_assemble_security_properties
639 function in lib/silcske/silcske.[ch].
641 * Changed notify client operation to fit better for notify messages
642 sent by server. The notify payload received from server is now
643 passed to the application (after parsing it to SilcNotifyPayload).
644 It is application's responsibility to retrieve the arguments
645 from the payload and show the message the way it wants. The message
646 sent by server is implementation specific.
648 * Changed public keys to comply with the protocol specification.
649 Old public keys are not supported anymore and are not compatible.
651 * Removed nickname from Channel Payload as the latest draft removed
652 it. The client must resolve the nickname from the NAMES command
653 reply received when it joined the channel.
655 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
657 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
659 * Fixed some errors in protocol specification drafts.
661 * Created lib/silccore/silcnotify.c to implement Notify Payload
662 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
663 generic payloads described by protocol specifications. The file
664 includes implementations for ID Payload and Argument Payload.
666 * Changed Command Payload implementation to use the new Argument
667 Payload. Changed command_xxxx_payload to command_payload_xxxx
668 to comply with SILC coding conventions.
670 * Added suppport for Argument Payload handling in Notify Payload
671 implementation as protocol requires it. Added the new support
672 into server and client lib as well.
674 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
676 * Added support for multiple nicknames on same channel. [n] is
677 added locally to the nickname if there are more than one same
678 nicknames on the channel.
680 * Server now sends all nicknames that matched WHOIS request.
681 Client also shows the list received from server.
683 * Added TOPIC command to client side. User can now set and show
684 current topic on channel.
686 * Added MOTD command to client and server. Also, server sends the
687 motd when client connects to the server.
689 * Changed version strings to comply ISO 8601.
691 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Fixed protocol error handling in client library. It should now
694 cope even if the SKE fails for some reason.
696 * Made new protocol specification drafts for submitting to IETF.
698 * Implemented TOPIC command to server in silcd/command.c.
700 * Added two new notify types into lib/silccore/silcnotify.h:
701 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
702 notify nickname change and topic setting/change on a channel.
704 * API change of command_reply operation in client library. The
705 application gets now the status type received from server as well.
707 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Removed the function just added to lib/silcutil/silcschedule.[ch].
711 * Cras fixed and optimized the packet handling even further and
712 it should work now. Minor change to the prototype of function
713 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
715 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Added new function into lib/silcutil/silcschedule.[ch]:
718 silc_schedule_with_fd to select() a specified fd. The function
719 returns after timeout expires or data arrives or goes. The
720 function is used by packet routines to wait that all data is
721 received from network.
723 * Fixed data reading from network in lib/silccore/silcpacket.c.
724 The code now assures that all data is read from the fd and then
725 continues packet processing. This was a bug fix since the code
726 used to drop some data in some circumstances.
728 * Added new function into lib/silcclient/client.[ch]:
729 silc_client_start_key_exchange to start key exchange after
730 connection has been established to server. The code internally
731 now uses this funtion but its main purpose was to provide it
732 for applications that perform their own connecting. After
733 application has created a connection it merely calls this
734 function to start the key exchange between client and server.
735 The library takes care of everything else after that.
737 Updated also lib/silcclient/README to explain the usage of
740 * Do not send to application information that connection has
741 been established. Application gets notified it by connect
744 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
746 * Applied cras's patch to add silc_schedule_one function. The
747 function runs scheduler once and returns.
749 * Fixed the scheduler after cras messed it up. The timeout
750 handling works now as it's supposed to work.
752 * Added into lib/silccore/ silcnotify.h to include notify
753 message types support. Changed silc_server_send_notify*
754 functions, in server.[ch], to support those new notify types.
755 Added the support for the notify types into client library,
756 as well. Added new notify client operation into ops.h in
759 * Changed silc_server_packet_send_to_channel to send normal
760 packets instead of just channel message packets. The function
761 is now used to send the notify packets to channels. It is not
762 used to send channel message packets anymore, as server never
765 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
766 va_arg()s as it seems to require it nowadays. I guess, if SILC
767 is compiled with older va_arg() the new code should work anyway.
769 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Splitted core library. Core library (lib/silccore) includes
772 now only SILC protocol specific core (and common) components.
773 Created new utility library (lib/silcutil) that includes more
774 generic purpose stuff. The stuff for util library was taken
775 from the old core library. This was minor and easy split.
777 * Created SILC Client Library (lib/silcclient) that includes
778 implementation of the SILC client without user interface. This
779 was major move from silc/ directory. The code has been changed
780 so that it is transparent towards the user interface. The
781 silc/ directory includes now the same user interface as before
782 and it uses the new client library. Read lib/silcclient/README.
783 Basicly, the client library performs everything else related
784 to SILC except user interface handling. Also, configuration
785 files are considered to be part of user interface and library
786 does not handle them.
788 This change also changed a lot of structures, function naming etc.
789 Most important change was that SilcClientWindow object was
790 renamed to SilcClientConnection in the client library. Created
791 also new file lib/silcclient/ops.h. Also added new files
792 silc/local_command.[ch] and silc/client_ops.[ch].
794 All these changes were made to make it easier for user interface
795 designers to create what ever user interface for the SILC client
798 It is also expected that the server will be moved to lib
799 directory as well and SILC Server Library will be created;
800 sometimes in the future.
802 * Removed Local commands from lib/silccore/silccommand.h as
803 they are application specific and new client library does not
804 handle any of those anymore.
806 * Several functions moved to lib/silcutil/silcutilc.[ch] from
807 old client implementation in silc/.
809 * Added support for callback functions in SILC_LOG_* macros.
810 Application can now set its own callbacks that will be called
811 instead of using the default functions that will always print
812 the debug messages to stderr (or stdout). Also, debugging can
813 now be disabled by setting silc_debug to FALSE and re-enabled by
814 setting it to TRUE. Note, that logging will still work even
815 if debugging is disabled.
817 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
818 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
819 silc_log_reset_debug_callbacks.
821 * To enable debugging in silc client one must give now -d
822 option on command line.
824 * Changed silc_schedule_init to automatically allocate task queues
825 if they are not allocated before calling it.
827 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
829 * Added GMP 3.1 into math library.
831 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
833 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
834 a channel in SILC network. The packet is used by servers and
835 routers to notify other routers that user has left a channel.
836 This little feature was missing until now. Added the feature
837 to protocol specification as well.
839 Added functions: silc_server_send_remove_channel_user and
840 silc_server_remove_channel_user into server.[ch].
842 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
843 lib/silccore/silcpacket.h. However, they are not implemented
846 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Fixed joining to a channel and sending channel messages
849 between server and router. The channel message sending should
850 now work inside a cell.
852 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Fixed the private message sending between server and router.
855 The private message sending should now work inside a cell.
857 * Added silc_server_replace_id into server.[ch] to replace
858 existing ID in the SILC network.
860 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
861 and silc_idlist_replace_server_id into idlist.[ch] in server.
863 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Fixed the server to server connections. Server can again now
866 connect to router. Router to router connections probably does
869 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Added dynamic protocol registering support. Now protocols can
872 registered and unregistered on the fly. Patch by cras.
874 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Added lib/contrib directory to hold routines that some platforms
877 don't have but are needed by SILC.
879 * Added getopt.c, getopt1.c and getopt.h from GNU C library
880 into lin/contrib to provide getopt() and getopt_long() for
881 those who don't have it.
883 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Added AWAY command to client. When away message is set and
886 client receives a private message packet the client automatically
887 replies to the sender with the away message.
889 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
890 bug seemed to be the cause of recent problems when compiling
893 * Added version detection support to SKE protocol specification
894 and added the new changes to the SKE implementation as well.
895 There were other minor changes in the SKE protocol as well.
897 Many changes in lib/silcske/silcske.[ch] and in
898 lib/silcske/payload.[ch].
900 * Added ^U functionality, clear input line. Patch from cras.
902 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Mainly small bugfixes on core library. Fixed some debugging
905 logging and buffer overflow in silclog.c.
907 * Updated config.sub and config.guess on the distribution tree.
909 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * Added command lagging support in server. Client may execute
912 commands now only once in two seconds.
914 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Optimized packet reception. MAC computation and checking is now
917 also more optimized. A lot previously duplicated code is now
918 used as generic by both client and server.
920 * Fixed key pair generation in clientutil.c
922 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Added into lib/silccore/silcbufutil.[ch] new function;
927 * Moved generic packet sending/encryption functions to
928 lib/silccore/silcpacket.[ch] from client and server. Some
929 rewriting of the functions.
931 * Moved all generic packet reception/decryption functions to
932 lib/silccore/silcpacket.[ch] from client and server. The
933 packet processing is now much cleaner in both client and server.
934 These were major changes in both client and server.
936 * Created many common functions in server to do packet sending.
937 Previously code were duplicated a lot, this has been removed
940 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Rewrote major parts of the ID cache system. Don't know
943 whether it is better now or not but at least the API is more
946 * Major rewrite on ID cache stuff on client because of the ID
947 cache API changes. Added idlist.c to client.
949 * Also major rewrite on ID cache stuff on server as well.
950 Major rewrite of idlist.[ch]. SilcXXXList's are now named
951 SilcXXXEntry's. We won't keep anymore idlist specific pointers
952 in hand, instead they are all put into the ID cache system now.
953 All server_idlist_* routines uses ID cache now instead of
954 traversing its own lists (those lists does not exist anymore).
955 SilcIDList though still exists. Also, SilcXXXEntry's are
958 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Finally made the SKE implementation compliant to the protocol
961 specification. All mp integers are now binary encoded as
962 opposed being HEX encoded.
964 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
967 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
968 functions: silc_[encode/decode]_pem. Also added function
969 silc_encode_pem_file to PEM encode with newlines ('\n') for
972 * SILC public keys are now encoded either PEM or binary. Same
973 option is for private keys as well. By default private keys
974 are binary encoded and public keys PEM encoded. Silly HEX
975 encoding were removed.
977 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
978 function to create fingerprints.
980 * Fixed a bug in SHA1; does not change the original data anymore.
982 * Partly implemented INFO command on client and server side.
983 Fixed CLEAR command. Changes to SERVER command; show current
984 server(s) when giving command without arguments. Added
985 VERSION command to client.
987 * Added check to server that unregistered connections cannot
988 execute commands (unless it is specificly allowed).
990 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Fixed screen refresh.
994 * Fixed channel joining bug from client. On some circumstances
995 client tried to join to a channel it had already joined.
997 * Added public key verification process into client's protocol.c.
998 The client now verifies the public key from user and saves
999 it into ~./silc/serverkeys/ directory.
1001 Added into: clientutil.[ch]: silc_client_verify_server_key.
1003 * Changed SKE protocol's silc_ske_initiator_finish function
1004 to accept callback function that verifies the received public
1005 key. Removed old silc_ske_verify_public_key function.
1007 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1010 silc_pkcs_private_key[_data]_set.
1012 * Made the password and public authentication more cleaner in
1013 server's protocol.c.
1015 * Removed historic and obsolete protocol `channel_auth' from
1016 both client and server.
1018 * Removed wrong way of sending command status messages from
1019 server to client in server's command.c. The old way violated
1020 protocol specification.
1022 Changes to silccore/silccommand.[ch]: removed
1023 silc_command_encode_status_payload -> not needed anymore,
1024 changed silc_command_encode_payload_va to accept extra
1025 argument on variable argument list. The argument type must
1026 now be provided to the function. Also, added new function:
1027 silc_command_encode_reply_payload_va which is same as
1028 normal command_encode_payload_va except command status type
1029 is provided as extra argument.
1031 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1033 * Added ~./silc directory handling. The directory includes the
1034 public and private keys for the client.
1036 Added silc_client_check_silc_dir, silc_client_create_identifier
1037 and silc_client_load_keys.
1039 * Implemented SILC protocol compliant public key. Added public
1040 and private key saving to and loading from files.
1042 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1043 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1044 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1045 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1046 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1048 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1049 silc_pkcs_load_[public/private]_key.
1051 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1053 * Added silc_server_get_route (route.[ch]) to get connection
1054 data for the fastest route for given ID.
1056 * Implemented INVITE command on client and server. The command
1057 were re-defined in the SILC Protocol Specification and the
1058 implementation now complies with the specification.
1060 * Implemented PING command on client and server.
1062 * Implemented NAMES command on client and server. The server side
1063 supports currently only normal server not router server yet.
1064 Some changes to NAMES definition in SILC protocol specification.
1066 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Implemented LEAVE command on client and server.
1070 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1071 again. This change was made to the protocol as well. Server
1072 should not violate the protocol specification anymore.
1074 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1077 was tested. SOCKS4 was not but should work anyway.
