1 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * silc_server_remove_channel_user checks now also global list
4 for channel and client.
6 * silc_server_new_channel_user checks now both local and global
7 list for channel and client. Fixed a bug in client id decoding.
8 Used to decode wrong buffer.
10 * silc_server_channel_message checks now both local and global
11 list for channel entry.
13 * Tested channel joining (hence JOIN) in router environment
14 successfully. Tested with two routers, two servers and two
17 * Tested channel message sending in router environment successfully.
19 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Added silc_server_save_channel_key into server.[ch] to save the
22 received channel key in Channel Key payload processing. It is
23 also used in JOIN command reply handling.
25 Equivalent function silc_client_save_channel_key added into
26 client.[ch] into client library.
28 * Changed JOIN command reply to send information whether the channel
29 was created or not (is existing already) and the channel key
30 payload. Changed protocol specs accordingly.
32 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
33 the request was sent by ID and not by nickname. Crashed on
36 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
39 now correctly save the received data.
41 * silc_server_free_sock_user_data now notifies routers in the
42 network about entities leaving the network.
44 At the same time implemented functions silc_server_remove_id
45 and silc_server_send_remove_id to receive and send REMOVE_ID
46 packets. The packet is used to notify routers in the network
47 about leaving entities. The ID removed will become invalid in
50 * Added function silc_idlist_del_server into server. Removes and
51 free's server entry from ID list.
53 * silc_server_private_message function now checks, if we are router,
54 that the destination ID really is valid ID, naturally.
56 * In router when NEW_ID packet is received (for new client) the
57 hash of the Client ID is saved in the ID Cache but the
58 client->nickname is set to NULL, instead of putting the hash
61 IDENTIFY command now also checks that client->nickname must be
62 valid. If it is not if will request the data from the server who
63 owns the client. Added new function
64 silc_server_command_identify_check.
66 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
67 to set the command to already allocated Command Payload.
69 * Tested private message sending in router environment with two
70 routers, two servers and two clients. Fixed minor bugs and now
73 * Fixed segfault from client's NAMES command. Used to crash if
76 * Forwarded packets must not be routed even if it is not destined
77 to the receiver. Changed server code comply with this.
79 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Added `require_reverse_mapping' boolean value to ServerParams
82 structure. If TRUE (not default) the server will require that
83 the connecting host has fully qualified domain name.
85 If the reverse mapping is not required and hostname could not be
86 found the IP address is used as hostname.
88 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
90 * Implemented version string checking to both client and server.
91 The check is incomplete currently due to the abnormal version
92 strings used in development version of SILC.
94 * Changed all command functions in server to use the new
97 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
99 * Changed char *data to unsigned char *data in ID Cache system to
100 support binary data as ID Cache data. Changed code to support
101 binary data in lib/silccore/idcache.c.
103 * Renamed silc_server_packet_relay_command_reply to
104 silc_server_command_reply as it is normal packet receiving
105 function. Rewrote the function to accept command replys for
106 servers and not only for clients.
108 * Mark remote router always as registered server if we are connecting
109 to it. Otherwise, commands sent by the router to us are ignored.
111 * All ID List find routines now returns the ID Cache Entry pointer
112 as well if requested.
114 * WHOIS command works now in router environment, tested with two
115 routers, two servers and two clients.
117 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
118 in router environment (as it is almost equivalent to WHOIS) but
119 hasn't been tested thoroughly. Added new functions:
121 silc_server_command_identify_parse
122 silc_server_command_identify_send_reply
123 silc_server_command_identify_from_client
124 silc_server_command_identify_from_server
126 * Disabled route cache adding because adding two different ID's with
127 same IP replaces the old cache entry thus giving wrong route.
128 The entry->router->connection is always the fastest route anyway
129 so route cache may not be needed. Of course, new routes maybe
130 established after receiving the ID when the entry->router->connection
131 might not be anymore the most optimal.
133 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Add route cache for received ID for fast routing.
137 * Added silc_server_packet_route to route received packet on router
138 that is not destined to us.
140 * Renamed silc_server_get_route to silc_server_route_get.
142 * Added id_string and id_string_len fields into SilcServer to
143 include encoded ServerID for fast comparing without excess
144 encoding of the ID's.
146 * Cleaned up WHOIS command on server side. Added following static
149 silc_server_command_whois_parse
150 silc_server_command_whois_check
151 silc_server_command_whois_send_reply
152 silc_server_command_whois_from_client
153 silc_server_command_whois_from_server
155 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
156 arguments in command replies. All command functions should be
157 updated to use this macro.
159 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Minor typo fixes on command reply handling on server.
163 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Added silc_server_command_add_to_channel internal routine to add
166 the client to the channel after router has created the channel and
167 sent command reply to the server.
169 * Added generic silc_server_send_command to send any command from
172 * Use static buffer with ID rendering instead of duplicating data.
174 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Fixed a channel user mode bug when joining to a channel server gave
177 everybody channel founder rights, oops.
179 * We mark ourselves as the router of the incoming server connection
180 if we are router ourselves. This way we can check in some packet
181 sending functions whether it is locally connected server. For
182 incoming router connections we put NULL.
184 * For router sending packets locally means now always sending the
185 packet cell wide; to local clients and local servers. For normal
186 server sending packet locally means sending it to only local
189 * Fixed the JOIN command to really work in router environment. If the
190 channel is created it is always created by the router. Router is
191 also responsible of making the initial joining to the channel,
192 sending JOIN notify to the sending server and distributing
193 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
194 does not exist server doesn't do anything else but forward the
195 command to the router which performs everything.
197 * Added silc_server_send_channel_key function to send the Channel Key
200 * Added silc_server_create_channel_key to create new channel key. The
201 channel key is now re-generated everytime someone joins or leaves
202 a channel, as protocol dictates. Note: channel->key_len is the
205 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
207 * Splitted server.[ch] finally. Created now packet_send.[ch] and
208 packet_receive.[ch] to separate packet sending and receiving
209 routines. The server.[ch] now includes everything else including
210 actual packet processing (writing and reading data) and other
213 Renamed silc_server_private_message_send_internal to
214 silc_server_send_private_message. The routine is still though
215 used only to relay private messages as server does not send
216 private messages itself.
218 Renamed silc_server_new_channel to silc_server_create_new_channel
219 and added new function sicl_server_new_channel that handles the
220 incoming New Channel packet. Added also new sending function
221 silc_server_send_new_channel to send New Channel Payload.
223 * Added new function silc_server_notify to process incoming notify
224 packet to the server/router. Server may then relay the notify
225 to clients if needed.
227 * Added new function silc_server_new_channel_user to process incoming
228 New Channel User packet. Router will redistribute the packet and
229 send JOIN notify to its local clients and locally connected servers
230 if needed. Normal server will send JOIN notify to its local client
231 on same channel when received this packet. Added also corresponding
232 sending function silc_server_send_new_channel_user to sent the
235 * Added boolean route argument to send_notif_to_channel and
236 packet_send_to_channel functions to attempt to route the packet
237 if it is TRUE and send only locally if it is FALSE.
239 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
241 * silc_server_replace_id now broadcasts the received replace ID
242 packet if it is not broadcast packet already. The router must
243 broadcast to inform other routers about changed ID.
245 * Added backpointer to server's router into SilcServer context in
246 silcd/server_internal.h.
248 * Fixed silc_server_packet_broadcast to send correct broadcast
251 * The channel key is now distributed to the local client as soon
252 as it is received from the router (in router environment) so that
253 no other packet may be sent for the channel until client has
256 * silc_server_remove_channel_user now broadcasts the received
257 Remove Channel User packet if it is not broadcast packet already.
258 The router must broadcast to inform other routers about removed
261 * Added users field into SilcPacketContext that is a reference count
262 of the context. One can increase the reference count by calling
263 silc_packet_context_dup which is now changed to just increase the
264 reference count instead of duplicating the data. The reference
265 count is decresed by calling silc_packet_context_free that will
266 free the data after the reference count hits zero.
268 For now on the packet context and everything allocated into it
269 (including the raw packet from network) must be freed by calling
270 the new silc_packet_context_free function. Added also new function
271 silc_packet_context_alloc that must be used now to allocate the
272 context. This also means that if a routine is asynchronous from
273 silc_[client/server]_packet_parse_type the packet context must
274 be duplicated by calling silc_packet_context_dup. Otherwise it
275 gets free'd after silc_[client/server]_packet_parse_type returns.
276 Also, one must remember that if packet is duplicated then its
277 reference count must be decresed by calling the free function as
278 many times as it was duplicated.
280 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
281 from both client and server.
283 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * Made joining to a channel working in router environment.
287 * Cleaned up JOIN command on server side and create function
288 silc_server_command_join_channel internal routine to make the
291 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * Changed silc_command_pending list to SilcDList. Also, added
294 `ident' field to SilcServerCommandPending structure to identify
295 the reply and to call correct callback.
297 Added silc_server_command_pending_check function to replace the
298 corresnponding macro. The silc_command_pending list is not
301 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
302 to set identifier to previously allocated Command Payload. It
303 is used to set identifier for command when resending Command
306 * Added silc_command_payload_encode_payload to encode Command
307 Payload buffer from SilcCommandPayload structure.
309 * Added silc_argument_payload_encode_payload to encode Argument
310 payload buffer from SilcArgumentPayload structure.
312 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Changed WHOIS command to support router connection on server side.
315 The whois request is always sent to router unless the server is
316 standalone server. After server has received the reply from the
317 router will it send the reply to the client.
319 * Added silc_server_packet_broadcast into silcd/server.[ch] to
320 broadcast received broadcast packet. The function is used only
321 by router. The broadcast packet is always sent to the router's
324 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
325 render given ID to printable string, for log files for example.
327 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
329 * Made basic router to router connections working. At least they
330 can now connect to each other but nothing really works the way
331 they are supposed - yet.
333 * Added new initiator token to RouterConnection configuration
334 file in silcd/serverconfig.[ch]. It is used to tell whether we
335 are the initiator to the remote router or whether we'll expect
336 the other end to connect.
338 * Moved registering of listener task to silc_server_init, hence
339 the server starts listenning as soon as it is run, even if it
340 does not have connections to other routers. Let's see how well
343 * Changed default connection retry timeouts for more suitable in
346 * Removed cipher and such arguments from silc_idlist_add_client
347 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
348 Added new function silc_idlist_add_data to add the keys and stuff
351 * Added SilcIDListData structure and added it to SilcClientEntry
352 and SilcServerEntry as their first field in the structure. This
353 way we can explicitly cast the ID entries to the SilcIDListData
354 structure and get common data for the entries. In past, we had
355 to first check what type of connection it is and then cast it to
356 correct ID entry type. Now, we can directly cast the opaque
357 pointer to the SilcIDListData (no matter what ID entry it actually
358 is) and get the data needed.
360 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
362 * Wow, found a bug in scheduler. The scheduler uninitialized itself
363 in some circumstances even if threre were timeout tasks, though not
364 IO tasks, but tasks anyway. Now fixed.
366 * Defined SilcServerConnection structure to hold connection specific
367 stuff about directly connected servers and routers. The definition
368 is currently in silcd/server_internal.h. I thought about having
369 a bit more important role fro this struct but for now it is used
370 only when connecting to other server (or router actually).
372 * Added connecting retry support in server when connecting to
373 router(s). The retry feature implement exponential backoff
374 algorithm. Also, added SilcServerParams structure to hold default
375 parameters for server. For now, it include these retry settings
376 and are hard coded. After server is moded to be as Silc Server
377 Library this structure will be more important.
379 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Changed client librarys channel->clients table to SilcList and
382 changed code accordingly.
384 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
386 * Changed client's channel table to SilcList and changed code
387 accordingly. Also changed SilcChannelClientEntry to include back-
388 pointer to the channel so that client entry can use that structure
389 as list as well and we have fast cross-reference to the channel.
390 This change dramatically decreased the complexity of channel
391 handling with client entry and vice versa (removed one extra
392 loop when searching for channel entry from many functions).
394 * Changed server->sim from table to SilcDList and changed code
397 * NAMES command can now be used from user interface. It will show
398 the user list on the channel, neatly.
400 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
401 Code now saves realname of the user if it becomes available.
403 * Renamed configure.in to configure.in.pre and made ./prepare
404 script to automatically add correct version string to
405 configure.in which it creates from configure.in.pre.
407 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
409 * NAMES command reply now shows users mode with the nickname when
412 * Moved silc_client_ch[u]mode[_char] functions from
413 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
414 place sucks, they are utility functions and should be in some
417 * Fixed some unsigned int's to unsigned short's. Patch by cras.
419 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
422 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
426 * Added TRQ (efficient deque and list library) into lib/trq. This is
427 a very good list library that is currently used in the SILC. Defined
428 SilcList API over the library because I didn't like the API very
429 much. See lib/trq/silclist.h for the API and examples of how to
430 use the API. Fixed various places in the code to use the new
431 SilcList API. The SilcList is meant for lists that has a structure
432 already defined as a list. It is not suitable to add just some
433 context to the list (in TRQ, the context is the list actually).
435 So, I defined SilcDList that can be used for the purpose where
436 predefined list structure does not exit. This can be used as
437 such list. Now some context just can be added to the SilcDList.
438 Currently this list is not used in the SILC just yet, though there
439 are a lot places where this can replace dynamically allocated
440 tables and I will fix these places, later, to use SilcDList.
441 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
442 and use TRQ internally).
444 Also fixed some annoying warning messages that the original TRQ
445 code generated. Also minor changes to TRQ's Makefile.in.
447 * Added support for querying by Client ID to both WHOIS and
448 IDENTIFY commands into server, as required by the protocol.
450 * Removed method function pointers from SilcBuffer structure. They
451 weren't used to anything and just increased the context size for
452 no good reason. This change also made silc_buffer_alloc and
453 silc_buffer_free functions inline functions.
455 * Disabled command flooding detection support until it's fixed so
456 that it accepts commands in but does not execute them more than once
459 * Added silc_net_localhost(), to return local hostname, into
460 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
461 that must be initialized before calling silc_client_init.
463 * Added new function: silc_server_send_notify_on_channels to send
464 notify messages to all channels client has joined. It is assured
465 that the message is sent only once per client.
467 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
468 lib/silcutil/silcutil.[ch] as silc_format function. The new
469 function is generic and is used by server as well, not only by
470 the logging routines.
472 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
473 the provided version string was not acceptable. Added new function:
474 silc_ske_check_version into lib/silcske/silcske.h. The function
475 must be implemented by the application (client or server) and it
476 does not reside in the SKE library. The function checks the version
477 string remote end sent.
479 * Added back pointers (to opaque context and to SilcSocketConnection)
480 into SilcPacketContext structure into lib/silccore/silcpacket.h.
482 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
483 duplicate packet context structure.
485 * Changed `notify' client operation to send same arguments as client
486 receives from server except for ID's. ID's are mapped to correct
487 ID entry and that is returned. Also, if channel entry is not sent
488 by server but the notify is for channel the channel entry is sent
489 to application (otherwise application doesn't know that it is for
490 channel (library gets it from packet's Destination ID)).
492 * Added silc_client_remove_from_channels into client library to
493 remove a client from all channels it has joined to. Used when
494 received SIGNOFF notify from server. Added also new function
495 silc_client_replace_from_channels to replace old ID entry with
496 new ID entry on all channels. Used when received NICK_CHANGE
499 * Fixed ID Cache list handling in silc_idlist_get_client in
500 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
501 to get (or query) client by ID.
505 * Added connection authentication status message defined by the
506 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
507 support for these into the code in client and server side.
509 * Added generic function silc_client_send_command to send any command
510 with variable argument list. Application should use this function
511 to send commands if the command functions provided by the library
512 does not suite for the application's user interface needs.
514 * Added new `failure' client operation. Application is notified about
515 received failure packet if client is executing a protocol. In this
516 case the protocol's execution has failed.
518 * Added SKE's end notify to send the SKE_SUCCESS notify message that
519 is required by the protocol.
521 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
522 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
525 * Added status flag to SilcSKE object to indicate realtime status
528 * Application receives now exactly same command reply arguments as
529 the library receives from server. However, if ID is received the
530 corresponding ID entry is returned to the application (eg. Client
531 ID is mapped to correct SilcClientEntry entry and that is returned).
532 Changed command_reply client operation due to this change.
534 * Changed all ID's in commands and in command replys as ID Payloads.
535 Change affected both client and server side codes.
537 All ID's sent in SILC network (with execption of ID's in SILC
538 Packet header) are sent in ID Payload to support variable length
541 * Server now notifies nick changes and notifies all clients on
542 the channels about the new nickname (about the new Client ID,
545 * Implemented CMODE command to change channel modes. Supports all
546 channel modes defined by the protocol specs except ban and invite
547 lists. (Also, private channel key mode is supported but support for
548 setting private channel key in client is missing, thus, this mode
549 has no effect on client side (except that server requires that the
550 client uses private channel key and normal channel traffic does not
553 Also, invite mode works per se, but INVITE command does not work
554 yet correctly, so you can set channel as invite only channel but
555 inviting clients to the channel does not work (it is yet to be
556 thought what's the best way to do it).
558 * Added new command SILC_COMMAND_CUMODE to change user mode on the
559 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
560 Implemented CUMODE command to change user's mode on the channel.
561 Supports all modes defined by the protocol specs.
563 * Added NAMES command reply to return users modes on the channel.
565 * Removed unnecessary and slow ciphers from lib/silccrypt.
567 * Set SO_KEEPALIVE option to connection sockets by default.
569 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
571 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
572 redefined the Notify Payload into protocol specs.
574 * Added silc_id_payload_parse_id to get ID directly from raw
577 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
580 accept searching by Client ID as well.
582 * Added support for LEAVE and SIGNOFF notify types in client library.
584 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
585 to parse ID Payload from raw data.
587 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * Added flags parameter into silc_ske_assemble_security_properties
590 function in lib/silcske/silcske.[ch].
592 * Changed notify client operation to fit better for notify messages
593 sent by server. The notify payload received from server is now
594 passed to the application (after parsing it to SilcNotifyPayload).
595 It is application's responsibility to retrieve the arguments
596 from the payload and show the message the way it wants. The message
597 sent by server is implementation specific.
599 * Changed public keys to comply with the protocol specification.
600 Old public keys are not supported anymore and are not compatible.
602 * Removed nickname from Channel Payload as the latest draft removed
603 it. The client must resolve the nickname from the NAMES command
604 reply received when it joined the channel.
606 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
608 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Fixed some errors in protocol specification drafts.
612 * Created lib/silccore/silcnotify.c to implement Notify Payload
613 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
614 generic payloads described by protocol specifications. The file
615 includes implementations for ID Payload and Argument Payload.
617 * Changed Command Payload implementation to use the new Argument
618 Payload. Changed command_xxxx_payload to command_payload_xxxx
619 to comply with SILC coding conventions.
621 * Added suppport for Argument Payload handling in Notify Payload
622 implementation as protocol requires it. Added the new support
623 into server and client lib as well.
625 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * Added support for multiple nicknames on same channel. [n] is
628 added locally to the nickname if there are more than one same
629 nicknames on the channel.
631 * Server now sends all nicknames that matched WHOIS request.
632 Client also shows the list received from server.
634 * Added TOPIC command to client side. User can now set and show
635 current topic on channel.
637 * Added MOTD command to client and server. Also, server sends the
638 motd when client connects to the server.
640 * Changed version strings to comply ISO 8601.
642 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Fixed protocol error handling in client library. It should now
645 cope even if the SKE fails for some reason.
647 * Made new protocol specification drafts for submitting to IETF.
649 * Implemented TOPIC command to server in silcd/command.c.
651 * Added two new notify types into lib/silccore/silcnotify.h:
652 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
653 notify nickname change and topic setting/change on a channel.
655 * API change of command_reply operation in client library. The
656 application gets now the status type received from server as well.
658 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
660 * Removed the function just added to lib/silcutil/silcschedule.[ch].
662 * Cras fixed and optimized the packet handling even further and
663 it should work now. Minor change to the prototype of function
664 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
666 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Added new function into lib/silcutil/silcschedule.[ch]:
669 silc_schedule_with_fd to select() a specified fd. The function
670 returns after timeout expires or data arrives or goes. The
671 function is used by packet routines to wait that all data is
672 received from network.
674 * Fixed data reading from network in lib/silccore/silcpacket.c.
675 The code now assures that all data is read from the fd and then
676 continues packet processing. This was a bug fix since the code
677 used to drop some data in some circumstances.
679 * Added new function into lib/silcclient/client.[ch]:
680 silc_client_start_key_exchange to start key exchange after
681 connection has been established to server. The code internally
682 now uses this funtion but its main purpose was to provide it
683 for applications that perform their own connecting. After
684 application has created a connection it merely calls this
685 function to start the key exchange between client and server.
686 The library takes care of everything else after that.
688 Updated also lib/silcclient/README to explain the usage of
691 * Do not send to application information that connection has
692 been established. Application gets notified it by connect
695 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
697 * Applied cras's patch to add silc_schedule_one function. The
698 function runs scheduler once and returns.
700 * Fixed the scheduler after cras messed it up. The timeout
701 handling works now as it's supposed to work.
703 * Added into lib/silccore/ silcnotify.h to include notify
704 message types support. Changed silc_server_send_notify*
705 functions, in server.[ch], to support those new notify types.
706 Added the support for the notify types into client library,
707 as well. Added new notify client operation into ops.h in
710 * Changed silc_server_packet_send_to_channel to send normal
711 packets instead of just channel message packets. The function
712 is now used to send the notify packets to channels. It is not
713 used to send channel message packets anymore, as server never
716 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
717 va_arg()s as it seems to require it nowadays. I guess, if SILC
718 is compiled with older va_arg() the new code should work anyway.
720 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Splitted core library. Core library (lib/silccore) includes
723 now only SILC protocol specific core (and common) components.
724 Created new utility library (lib/silcutil) that includes more
725 generic purpose stuff. The stuff for util library was taken
726 from the old core library. This was minor and easy split.
728 * Created SILC Client Library (lib/silcclient) that includes
729 implementation of the SILC client without user interface. This
730 was major move from silc/ directory. The code has been changed
731 so that it is transparent towards the user interface. The
732 silc/ directory includes now the same user interface as before
733 and it uses the new client library. Read lib/silcclient/README.
734 Basicly, the client library performs everything else related
735 to SILC except user interface handling. Also, configuration
736 files are considered to be part of user interface and library
737 does not handle them.
739 This change also changed a lot of structures, function naming etc.
740 Most important change was that SilcClientWindow object was
741 renamed to SilcClientConnection in the client library. Created
742 also new file lib/silcclient/ops.h. Also added new files
743 silc/local_command.[ch] and silc/client_ops.[ch].
745 All these changes were made to make it easier for user interface
746 designers to create what ever user interface for the SILC client
749 It is also expected that the server will be moved to lib
750 directory as well and SILC Server Library will be created;
751 sometimes in the future.
753 * Removed Local commands from lib/silccore/silccommand.h as
754 they are application specific and new client library does not
755 handle any of those anymore.
757 * Several functions moved to lib/silcutil/silcutilc.[ch] from
758 old client implementation in silc/.
760 * Added support for callback functions in SILC_LOG_* macros.
761 Application can now set its own callbacks that will be called
762 instead of using the default functions that will always print
763 the debug messages to stderr (or stdout). Also, debugging can
764 now be disabled by setting silc_debug to FALSE and re-enabled by
765 setting it to TRUE. Note, that logging will still work even
766 if debugging is disabled.
768 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
769 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
770 silc_log_reset_debug_callbacks.
772 * To enable debugging in silc client one must give now -d
773 option on command line.
775 * Changed silc_schedule_init to automatically allocate task queues
776 if they are not allocated before calling it.
778 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Added GMP 3.1 into math library.
782 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
785 a channel in SILC network. The packet is used by servers and
786 routers to notify other routers that user has left a channel.
787 This little feature was missing until now. Added the feature
788 to protocol specification as well.
790 Added functions: silc_server_send_remove_channel_user and
791 silc_server_remove_channel_user into server.[ch].
793 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
794 lib/silccore/silcpacket.h. However, they are not implemented
797 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
799 * Fixed joining to a channel and sending channel messages
800 between server and router. The channel message sending should
801 now work inside a cell.
803 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
805 * Fixed the private message sending between server and router.
806 The private message sending should now work inside a cell.
808 * Added silc_server_replace_id into server.[ch] to replace
809 existing ID in the SILC network.
811 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
812 and silc_idlist_replace_server_id into idlist.[ch] in server.
814 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
816 * Fixed the server to server connections. Server can again now
817 connect to router. Router to router connections probably does
820 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Added dynamic protocol registering support. Now protocols can
823 registered and unregistered on the fly. Patch by cras.
825 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Added lib/contrib directory to hold routines that some platforms
828 don't have but are needed by SILC.
830 * Added getopt.c, getopt1.c and getopt.h from GNU C library
831 into lin/contrib to provide getopt() and getopt_long() for
832 those who don't have it.
834 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added AWAY command to client. When away message is set and
837 client receives a private message packet the client automatically
838 replies to the sender with the away message.
840 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
841 bug seemed to be the cause of recent problems when compiling
844 * Added version detection support to SKE protocol specification
845 and added the new changes to the SKE implementation as well.
846 There were other minor changes in the SKE protocol as well.
848 Many changes in lib/silcske/silcske.[ch] and in
849 lib/silcske/payload.[ch].
851 * Added ^U functionality, clear input line. Patch from cras.
853 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Mainly small bugfixes on core library. Fixed some debugging
856 logging and buffer overflow in silclog.c.
858 * Updated config.sub and config.guess on the distribution tree.
860 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Added command lagging support in server. Client may execute
863 commands now only once in two seconds.
865 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Optimized packet reception. MAC computation and checking is now
868 also more optimized. A lot previously duplicated code is now
869 used as generic by both client and server.
871 * Fixed key pair generation in clientutil.c
873 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Added into lib/silccore/silcbufutil.[ch] new function;
878 * Moved generic packet sending/encryption functions to
879 lib/silccore/silcpacket.[ch] from client and server. Some
880 rewriting of the functions.
882 * Moved all generic packet reception/decryption functions to
883 lib/silccore/silcpacket.[ch] from client and server. The
884 packet processing is now much cleaner in both client and server.
885 These were major changes in both client and server.
887 * Created many common functions in server to do packet sending.
888 Previously code were duplicated a lot, this has been removed
891 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Rewrote major parts of the ID cache system. Don't know
894 whether it is better now or not but at least the API is more
897 * Major rewrite on ID cache stuff on client because of the ID
898 cache API changes. Added idlist.c to client.
900 * Also major rewrite on ID cache stuff on server as well.
901 Major rewrite of idlist.[ch]. SilcXXXList's are now named
902 SilcXXXEntry's. We won't keep anymore idlist specific pointers
903 in hand, instead they are all put into the ID cache system now.
904 All server_idlist_* routines uses ID cache now instead of
905 traversing its own lists (those lists does not exist anymore).
906 SilcIDList though still exists. Also, SilcXXXEntry's are
909 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * Finally made the SKE implementation compliant to the protocol
912 specification. All mp integers are now binary encoded as
913 opposed being HEX encoded.
915 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
918 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
919 functions: silc_[encode/decode]_pem. Also added function
920 silc_encode_pem_file to PEM encode with newlines ('\n') for
923 * SILC public keys are now encoded either PEM or binary. Same
924 option is for private keys as well. By default private keys
925 are binary encoded and public keys PEM encoded. Silly HEX
926 encoding were removed.
928 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
929 function to create fingerprints.
931 * Fixed a bug in SHA1; does not change the original data anymore.
933 * Partly implemented INFO command on client and server side.
934 Fixed CLEAR command. Changes to SERVER command; show current
935 server(s) when giving command without arguments. Added
936 VERSION command to client.
938 * Added check to server that unregistered connections cannot
939 execute commands (unless it is specificly allowed).
941 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Fixed screen refresh.
945 * Fixed channel joining bug from client. On some circumstances
946 client tried to join to a channel it had already joined.
948 * Added public key verification process into client's protocol.c.
949 The client now verifies the public key from user and saves
950 it into ~./silc/serverkeys/ directory.
952 Added into: clientutil.[ch]: silc_client_verify_server_key.
954 * Changed SKE protocol's silc_ske_initiator_finish function
955 to accept callback function that verifies the received public
956 key. Removed old silc_ske_verify_public_key function.
958 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
961 silc_pkcs_private_key[_data]_set.
963 * Made the password and public authentication more cleaner in
966 * Removed historic and obsolete protocol `channel_auth' from
967 both client and server.
969 * Removed wrong way of sending command status messages from
970 server to client in server's command.c. The old way violated
971 protocol specification.
973 Changes to silccore/silccommand.[ch]: removed
974 silc_command_encode_status_payload -> not needed anymore,
975 changed silc_command_encode_payload_va to accept extra
976 argument on variable argument list. The argument type must
977 now be provided to the function. Also, added new function:
978 silc_command_encode_reply_payload_va which is same as
979 normal command_encode_payload_va except command status type
980 is provided as extra argument.
982 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added ~./silc directory handling. The directory includes the
985 public and private keys for the client.
987 Added silc_client_check_silc_dir, silc_client_create_identifier
988 and silc_client_load_keys.
990 * Implemented SILC protocol compliant public key. Added public
991 and private key saving to and loading from files.
993 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
994 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
995 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
996 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
997 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
999 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1000 silc_pkcs_load_[public/private]_key.
1002 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1004 * Added silc_server_get_route (route.[ch]) to get connection
1005 data for the fastest route for given ID.
1007 * Implemented INVITE command on client and server. The command
1008 were re-defined in the SILC Protocol Specification and the
1009 implementation now complies with the specification.
1011 * Implemented PING command on client and server.
1013 * Implemented NAMES command on client and server. The server side
1014 supports currently only normal server not router server yet.
1015 Some changes to NAMES definition in SILC protocol specification.
1017 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Implemented LEAVE command on client and server.
1021 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1022 again. This change was made to the protocol as well. Server
1023 should not violate the protocol specification anymore.
1025 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1028 was tested. SOCKS4 was not but should work anyway.
