3 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4 now correctly save the received data.
6 * silc_server_free_sock_user_data now notifies routers in the
7 network about entities leaving the network.
9 At the same time implemented functions silc_server_remove_id
10 and silc_server_send_remove_id to receive and send REMOVE_ID
11 packets. The packet is used to notify routers in the network
12 about leaving entities. The ID removed will become invalid in
15 * Added function silc_idlist_del_server into server. Removes and
16 free's server entry from ID list.
18 * silc_server_private_message function now checks, if we are router,
19 that the destination ID really is valid ID, naturally.
21 * In router when NEW_ID packet is received (for new client) the
22 hash of the Client ID is saved in the ID Cache but the
23 client->nickname is set to NULL, instead of putting the hash
26 IDENTIFY command now also checks that client->nickname must be
27 valid. If it is not if will request the data from the server who
28 owns the client. Added new function
29 silc_server_command_identify_check.
31 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
32 to set the command to already allocated Command Payload.
34 * Tested private message sending in router environment with two
35 routers, two servers and two clients. Fixed minor bugs and now
38 * Fixed segfault from client's NAMES command. Used to crash if
41 * Forwarded packets must not be routed even if it is not destined
42 to the receiver. Changed server code comply with this.
44 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
46 * Added `require_reverse_mapping' boolean value to ServerParams
47 structure. If TRUE (not default) the server will require that
48 the connecting host has fully qualified domain name.
50 If the reverse mapping is not required and hostname could not be
51 found the IP address is used as hostname.
53 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Implemented version string checking to both client and server.
56 The check is incomplete currently due to the abnormal version
57 strings used in development version of SILC.
59 * Changed all command functions in server to use the new
62 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
64 * Changed char *data to unsigned char *data in ID Cache system to
65 support binary data as ID Cache data. Changed code to support
66 binary data in lib/silccore/idcache.c.
68 * Renamed silc_server_packet_relay_command_reply to
69 silc_server_command_reply as it is normal packet receiving
70 function. Rewrote the function to accept command replys for
71 servers and not only for clients.
73 * Mark remote router always as registered server if we are connecting
74 to it. Otherwise, commands sent by the router to us are ignored.
76 * All ID List find routines now returns the ID Cache Entry pointer
79 * WHOIS command works now in router environment, tested with two
80 routers, two servers and two clients.
82 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
83 in router environment (as it is almost equivalent to WHOIS) but
84 hasn't been tested thoroughly. Added new functions:
86 silc_server_command_identify_parse
87 silc_server_command_identify_send_reply
88 silc_server_command_identify_from_client
89 silc_server_command_identify_from_server
91 * Disabled route cache adding because adding two different ID's with
92 same IP replaces the old cache entry thus giving wrong route.
93 The entry->router->connection is always the fastest route anyway
94 so route cache may not be needed. Of course, new routes maybe
95 established after receiving the ID when the entry->router->connection
96 might not be anymore the most optimal.
98 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
100 * Add route cache for received ID for fast routing.
102 * Added silc_server_packet_route to route received packet on router
103 that is not destined to us.
105 * Renamed silc_server_get_route to silc_server_route_get.
107 * Added id_string and id_string_len fields into SilcServer to
108 include encoded ServerID for fast comparing without excess
109 encoding of the ID's.
111 * Cleaned up WHOIS command on server side. Added following static
114 silc_server_command_whois_parse
115 silc_server_command_whois_check
116 silc_server_command_whois_send_reply
117 silc_server_command_whois_from_client
118 silc_server_command_whois_from_server
120 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
121 arguments in command replies. All command functions should be
122 updated to use this macro.
124 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
126 * Minor typo fixes on command reply handling on server.
128 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
130 * Added silc_server_command_add_to_channel internal routine to add
131 the client to the channel after router has created the channel and
132 sent command reply to the server.
134 * Added generic silc_server_send_command to send any command from
137 * Use static buffer with ID rendering instead of duplicating data.
139 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Fixed a channel user mode bug when joining to a channel server gave
142 everybody channel founder rights, oops.
144 * We mark ourselves as the router of the incoming server connection
145 if we are router ourselves. This way we can check in some packet
146 sending functions whether it is locally connected server. For
147 incoming router connections we put NULL.
149 * For router sending packets locally means now always sending the
150 packet cell wide; to local clients and local servers. For normal
151 server sending packet locally means sending it to only local
154 * Fixed the JOIN command to really work in router environment. If the
155 channel is created it is always created by the router. Router is
156 also responsible of making the initial joining to the channel,
157 sending JOIN notify to the sending server and distributing
158 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
159 does not exist server doesn't do anything else but forward the
160 command to the router which performs everything.
162 * Added silc_server_send_channel_key function to send the Channel Key
165 * Added silc_server_create_channel_key to create new channel key. The
166 channel key is now re-generated everytime someone joins or leaves
167 a channel, as protocol dictates. Note: channel->key_len is the
170 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
172 * Splitted server.[ch] finally. Created now packet_send.[ch] and
173 packet_receive.[ch] to separate packet sending and receiving
174 routines. The server.[ch] now includes everything else including
175 actual packet processing (writing and reading data) and other
178 Renamed silc_server_private_message_send_internal to
179 silc_server_send_private_message. The routine is still though
180 used only to relay private messages as server does not send
181 private messages itself.
183 Renamed silc_server_new_channel to silc_server_create_new_channel
184 and added new function sicl_server_new_channel that handles the
185 incoming New Channel packet. Added also new sending function
186 silc_server_send_new_channel to send New Channel Payload.
188 * Added new function silc_server_notify to process incoming notify
189 packet to the server/router. Server may then relay the notify
190 to clients if needed.
192 * Added new function silc_server_new_channel_user to process incoming
193 New Channel User packet. Router will redistribute the packet and
194 send JOIN notify to its local clients and locally connected servers
195 if needed. Normal server will send JOIN notify to its local client
196 on same channel when received this packet. Added also corresponding
197 sending function silc_server_send_new_channel_user to sent the
200 * Added boolean route argument to send_notif_to_channel and
201 packet_send_to_channel functions to attempt to route the packet
202 if it is TRUE and send only locally if it is FALSE.
204 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
206 * silc_server_replace_id now broadcasts the received replace ID
207 packet if it is not broadcast packet already. The router must
208 broadcast to inform other routers about changed ID.
210 * Added backpointer to server's router into SilcServer context in
211 silcd/server_internal.h.
213 * Fixed silc_server_packet_broadcast to send correct broadcast
216 * The channel key is now distributed to the local client as soon
217 as it is received from the router (in router environment) so that
218 no other packet may be sent for the channel until client has
221 * silc_server_remove_channel_user now broadcasts the received
222 Remove Channel User packet if it is not broadcast packet already.
223 The router must broadcast to inform other routers about removed
226 * Added users field into SilcPacketContext that is a reference count
227 of the context. One can increase the reference count by calling
228 silc_packet_context_dup which is now changed to just increase the
229 reference count instead of duplicating the data. The reference
230 count is decresed by calling silc_packet_context_free that will
231 free the data after the reference count hits zero.
233 For now on the packet context and everything allocated into it
234 (including the raw packet from network) must be freed by calling
235 the new silc_packet_context_free function. Added also new function
236 silc_packet_context_alloc that must be used now to allocate the
237 context. This also means that if a routine is asynchronous from
238 silc_[client/server]_packet_parse_type the packet context must
239 be duplicated by calling silc_packet_context_dup. Otherwise it
240 gets free'd after silc_[client/server]_packet_parse_type returns.
241 Also, one must remember that if packet is duplicated then its
242 reference count must be decresed by calling the free function as
243 many times as it was duplicated.
245 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
246 from both client and server.
248 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Made joining to a channel working in router environment.
252 * Cleaned up JOIN command on server side and create function
253 silc_server_command_join_channel internal routine to make the
256 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Changed silc_command_pending list to SilcDList. Also, added
259 `ident' field to SilcServerCommandPending structure to identify
260 the reply and to call correct callback.
262 Added silc_server_command_pending_check function to replace the
263 corresnponding macro. The silc_command_pending list is not
266 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
267 to set identifier to previously allocated Command Payload. It
268 is used to set identifier for command when resending Command
271 * Added silc_command_payload_encode_payload to encode Command
272 Payload buffer from SilcCommandPayload structure.
274 * Added silc_argument_payload_encode_payload to encode Argument
275 payload buffer from SilcArgumentPayload structure.
277 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Changed WHOIS command to support router connection on server side.
280 The whois request is always sent to router unless the server is
281 standalone server. After server has received the reply from the
282 router will it send the reply to the client.
284 * Added silc_server_packet_broadcast into silcd/server.[ch] to
285 broadcast received broadcast packet. The function is used only
286 by router. The broadcast packet is always sent to the router's
289 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
290 render given ID to printable string, for log files for example.
292 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Made basic router to router connections working. At least they
295 can now connect to each other but nothing really works the way
296 they are supposed - yet.
298 * Added new initiator token to RouterConnection configuration
299 file in silcd/serverconfig.[ch]. It is used to tell whether we
300 are the initiator to the remote router or whether we'll expect
301 the other end to connect.
303 * Moved registering of listener task to silc_server_init, hence
304 the server starts listenning as soon as it is run, even if it
305 does not have connections to other routers. Let's see how well
308 * Changed default connection retry timeouts for more suitable in
311 * Removed cipher and such arguments from silc_idlist_add_client
312 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
313 Added new function silc_idlist_add_data to add the keys and stuff
316 * Added SilcIDListData structure and added it to SilcClientEntry
317 and SilcServerEntry as their first field in the structure. This
318 way we can explicitly cast the ID entries to the SilcIDListData
319 structure and get common data for the entries. In past, we had
320 to first check what type of connection it is and then cast it to
321 correct ID entry type. Now, we can directly cast the opaque
322 pointer to the SilcIDListData (no matter what ID entry it actually
323 is) and get the data needed.
325 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * Wow, found a bug in scheduler. The scheduler uninitialized itself
328 in some circumstances even if threre were timeout tasks, though not
329 IO tasks, but tasks anyway. Now fixed.
331 * Defined SilcServerConnection structure to hold connection specific
332 stuff about directly connected servers and routers. The definition
333 is currently in silcd/server_internal.h. I thought about having
334 a bit more important role fro this struct but for now it is used
335 only when connecting to other server (or router actually).
337 * Added connecting retry support in server when connecting to
338 router(s). The retry feature implement exponential backoff
339 algorithm. Also, added SilcServerParams structure to hold default
340 parameters for server. For now, it include these retry settings
341 and are hard coded. After server is moded to be as Silc Server
342 Library this structure will be more important.
344 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Changed client librarys channel->clients table to SilcList and
347 changed code accordingly.
349 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Changed client's channel table to SilcList and changed code
352 accordingly. Also changed SilcChannelClientEntry to include back-
353 pointer to the channel so that client entry can use that structure
354 as list as well and we have fast cross-reference to the channel.
355 This change dramatically decreased the complexity of channel
356 handling with client entry and vice versa (removed one extra
357 loop when searching for channel entry from many functions).
359 * Changed server->sim from table to SilcDList and changed code
362 * NAMES command can now be used from user interface. It will show
363 the user list on the channel, neatly.
365 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
366 Code now saves realname of the user if it becomes available.
368 * Renamed configure.in to configure.in.pre and made ./prepare
369 script to automatically add correct version string to
370 configure.in which it creates from configure.in.pre.
372 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
374 * NAMES command reply now shows users mode with the nickname when
377 * Moved silc_client_ch[u]mode[_char] functions from
378 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
379 place sucks, they are utility functions and should be in some
382 * Fixed some unsigned int's to unsigned short's. Patch by cras.
384 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
387 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
391 * Added TRQ (efficient deque and list library) into lib/trq. This is
392 a very good list library that is currently used in the SILC. Defined
393 SilcList API over the library because I didn't like the API very
394 much. See lib/trq/silclist.h for the API and examples of how to
395 use the API. Fixed various places in the code to use the new
396 SilcList API. The SilcList is meant for lists that has a structure
397 already defined as a list. It is not suitable to add just some
398 context to the list (in TRQ, the context is the list actually).
400 So, I defined SilcDList that can be used for the purpose where
401 predefined list structure does not exit. This can be used as
402 such list. Now some context just can be added to the SilcDList.
403 Currently this list is not used in the SILC just yet, though there
404 are a lot places where this can replace dynamically allocated
405 tables and I will fix these places, later, to use SilcDList.
406 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
407 and use TRQ internally).
409 Also fixed some annoying warning messages that the original TRQ
410 code generated. Also minor changes to TRQ's Makefile.in.
412 * Added support for querying by Client ID to both WHOIS and
413 IDENTIFY commands into server, as required by the protocol.
415 * Removed method function pointers from SilcBuffer structure. They
416 weren't used to anything and just increased the context size for
417 no good reason. This change also made silc_buffer_alloc and
418 silc_buffer_free functions inline functions.
420 * Disabled command flooding detection support until it's fixed so
421 that it accepts commands in but does not execute them more than once
424 * Added silc_net_localhost(), to return local hostname, into
425 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
426 that must be initialized before calling silc_client_init.
428 * Added new function: silc_server_send_notify_on_channels to send
429 notify messages to all channels client has joined. It is assured
430 that the message is sent only once per client.
432 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
433 lib/silcutil/silcutil.[ch] as silc_format function. The new
434 function is generic and is used by server as well, not only by
435 the logging routines.
437 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
438 the provided version string was not acceptable. Added new function:
439 silc_ske_check_version into lib/silcske/silcske.h. The function
440 must be implemented by the application (client or server) and it
441 does not reside in the SKE library. The function checks the version
442 string remote end sent.
444 * Added back pointers (to opaque context and to SilcSocketConnection)
445 into SilcPacketContext structure into lib/silccore/silcpacket.h.
447 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
448 duplicate packet context structure.
450 * Changed `notify' client operation to send same arguments as client
451 receives from server except for ID's. ID's are mapped to correct
452 ID entry and that is returned. Also, if channel entry is not sent
453 by server but the notify is for channel the channel entry is sent
454 to application (otherwise application doesn't know that it is for
455 channel (library gets it from packet's Destination ID)).
457 * Added silc_client_remove_from_channels into client library to
458 remove a client from all channels it has joined to. Used when
459 received SIGNOFF notify from server. Added also new function
460 silc_client_replace_from_channels to replace old ID entry with
461 new ID entry on all channels. Used when received NICK_CHANGE
464 * Fixed ID Cache list handling in silc_idlist_get_client in
465 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
466 to get (or query) client by ID.
470 * Added connection authentication status message defined by the
471 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
472 support for these into the code in client and server side.
474 * Added generic function silc_client_send_command to send any command
475 with variable argument list. Application should use this function
476 to send commands if the command functions provided by the library
477 does not suite for the application's user interface needs.
479 * Added new `failure' client operation. Application is notified about
480 received failure packet if client is executing a protocol. In this
481 case the protocol's execution has failed.
483 * Added SKE's end notify to send the SKE_SUCCESS notify message that
484 is required by the protocol.
486 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
487 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
490 * Added status flag to SilcSKE object to indicate realtime status
493 * Application receives now exactly same command reply arguments as
494 the library receives from server. However, if ID is received the
495 corresponding ID entry is returned to the application (eg. Client
496 ID is mapped to correct SilcClientEntry entry and that is returned).
497 Changed command_reply client operation due to this change.
499 * Changed all ID's in commands and in command replys as ID Payloads.
500 Change affected both client and server side codes.
502 All ID's sent in SILC network (with execption of ID's in SILC
503 Packet header) are sent in ID Payload to support variable length
506 * Server now notifies nick changes and notifies all clients on
507 the channels about the new nickname (about the new Client ID,
510 * Implemented CMODE command to change channel modes. Supports all
511 channel modes defined by the protocol specs except ban and invite
512 lists. (Also, private channel key mode is supported but support for
513 setting private channel key in client is missing, thus, this mode
514 has no effect on client side (except that server requires that the
515 client uses private channel key and normal channel traffic does not
518 Also, invite mode works per se, but INVITE command does not work
519 yet correctly, so you can set channel as invite only channel but
520 inviting clients to the channel does not work (it is yet to be
521 thought what's the best way to do it).
523 * Added new command SILC_COMMAND_CUMODE to change user mode on the
524 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
525 Implemented CUMODE command to change user's mode on the channel.
526 Supports all modes defined by the protocol specs.
528 * Added NAMES command reply to return users modes on the channel.
530 * Removed unnecessary and slow ciphers from lib/silccrypt.
532 * Set SO_KEEPALIVE option to connection sockets by default.
534 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
536 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
537 redefined the Notify Payload into protocol specs.
539 * Added silc_id_payload_parse_id to get ID directly from raw
542 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
545 accept searching by Client ID as well.
547 * Added support for LEAVE and SIGNOFF notify types in client library.
549 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
550 to parse ID Payload from raw data.
552 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
554 * Added flags parameter into silc_ske_assemble_security_properties
555 function in lib/silcske/silcske.[ch].
557 * Changed notify client operation to fit better for notify messages
558 sent by server. The notify payload received from server is now
559 passed to the application (after parsing it to SilcNotifyPayload).
560 It is application's responsibility to retrieve the arguments
561 from the payload and show the message the way it wants. The message
562 sent by server is implementation specific.
564 * Changed public keys to comply with the protocol specification.
565 Old public keys are not supported anymore and are not compatible.
567 * Removed nickname from Channel Payload as the latest draft removed
568 it. The client must resolve the nickname from the NAMES command
569 reply received when it joined the channel.
571 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
573 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Fixed some errors in protocol specification drafts.
577 * Created lib/silccore/silcnotify.c to implement Notify Payload
578 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
579 generic payloads described by protocol specifications. The file
580 includes implementations for ID Payload and Argument Payload.
582 * Changed Command Payload implementation to use the new Argument
583 Payload. Changed command_xxxx_payload to command_payload_xxxx
584 to comply with SILC coding conventions.
586 * Added suppport for Argument Payload handling in Notify Payload
587 implementation as protocol requires it. Added the new support
588 into server and client lib as well.
590 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Added support for multiple nicknames on same channel. [n] is
593 added locally to the nickname if there are more than one same
594 nicknames on the channel.
596 * Server now sends all nicknames that matched WHOIS request.
597 Client also shows the list received from server.
599 * Added TOPIC command to client side. User can now set and show
600 current topic on channel.
602 * Added MOTD command to client and server. Also, server sends the
603 motd when client connects to the server.
605 * Changed version strings to comply ISO 8601.
607 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
609 * Fixed protocol error handling in client library. It should now
610 cope even if the SKE fails for some reason.
612 * Made new protocol specification drafts for submitting to IETF.
614 * Implemented TOPIC command to server in silcd/command.c.
616 * Added two new notify types into lib/silccore/silcnotify.h:
617 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
618 notify nickname change and topic setting/change on a channel.
620 * API change of command_reply operation in client library. The
621 application gets now the status type received from server as well.
623 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
625 * Removed the function just added to lib/silcutil/silcschedule.[ch].
627 * Cras fixed and optimized the packet handling even further and
628 it should work now. Minor change to the prototype of function
629 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
631 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Added new function into lib/silcutil/silcschedule.[ch]:
634 silc_schedule_with_fd to select() a specified fd. The function
635 returns after timeout expires or data arrives or goes. The
636 function is used by packet routines to wait that all data is
637 received from network.
639 * Fixed data reading from network in lib/silccore/silcpacket.c.
640 The code now assures that all data is read from the fd and then
641 continues packet processing. This was a bug fix since the code
642 used to drop some data in some circumstances.
644 * Added new function into lib/silcclient/client.[ch]:
645 silc_client_start_key_exchange to start key exchange after
646 connection has been established to server. The code internally
647 now uses this funtion but its main purpose was to provide it
648 for applications that perform their own connecting. After
649 application has created a connection it merely calls this
650 function to start the key exchange between client and server.
651 The library takes care of everything else after that.
653 Updated also lib/silcclient/README to explain the usage of
656 * Do not send to application information that connection has
657 been established. Application gets notified it by connect
660 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
662 * Applied cras's patch to add silc_schedule_one function. The
663 function runs scheduler once and returns.
665 * Fixed the scheduler after cras messed it up. The timeout
666 handling works now as it's supposed to work.
668 * Added into lib/silccore/ silcnotify.h to include notify
669 message types support. Changed silc_server_send_notify*
670 functions, in server.[ch], to support those new notify types.
671 Added the support for the notify types into client library,
672 as well. Added new notify client operation into ops.h in
675 * Changed silc_server_packet_send_to_channel to send normal
676 packets instead of just channel message packets. The function
677 is now used to send the notify packets to channels. It is not
678 used to send channel message packets anymore, as server never
681 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
682 va_arg()s as it seems to require it nowadays. I guess, if SILC
683 is compiled with older va_arg() the new code should work anyway.
685 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Splitted core library. Core library (lib/silccore) includes
688 now only SILC protocol specific core (and common) components.
689 Created new utility library (lib/silcutil) that includes more
690 generic purpose stuff. The stuff for util library was taken
691 from the old core library. This was minor and easy split.
693 * Created SILC Client Library (lib/silcclient) that includes
694 implementation of the SILC client without user interface. This
695 was major move from silc/ directory. The code has been changed
696 so that it is transparent towards the user interface. The
697 silc/ directory includes now the same user interface as before
698 and it uses the new client library. Read lib/silcclient/README.
699 Basicly, the client library performs everything else related
700 to SILC except user interface handling. Also, configuration
701 files are considered to be part of user interface and library
702 does not handle them.
704 This change also changed a lot of structures, function naming etc.
705 Most important change was that SilcClientWindow object was
706 renamed to SilcClientConnection in the client library. Created
707 also new file lib/silcclient/ops.h. Also added new files
708 silc/local_command.[ch] and silc/client_ops.[ch].
710 All these changes were made to make it easier for user interface
711 designers to create what ever user interface for the SILC client
714 It is also expected that the server will be moved to lib
715 directory as well and SILC Server Library will be created;
716 sometimes in the future.
718 * Removed Local commands from lib/silccore/silccommand.h as
719 they are application specific and new client library does not
720 handle any of those anymore.
722 * Several functions moved to lib/silcutil/silcutilc.[ch] from
723 old client implementation in silc/.
725 * Added support for callback functions in SILC_LOG_* macros.
726 Application can now set its own callbacks that will be called
727 instead of using the default functions that will always print
728 the debug messages to stderr (or stdout). Also, debugging can
729 now be disabled by setting silc_debug to FALSE and re-enabled by
730 setting it to TRUE. Note, that logging will still work even
731 if debugging is disabled.
733 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
734 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
735 silc_log_reset_debug_callbacks.
737 * To enable debugging in silc client one must give now -d
738 option on command line.
740 * Changed silc_schedule_init to automatically allocate task queues
741 if they are not allocated before calling it.
743 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Added GMP 3.1 into math library.
747 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
750 a channel in SILC network. The packet is used by servers and
751 routers to notify other routers that user has left a channel.
752 This little feature was missing until now. Added the feature
753 to protocol specification as well.
755 Added functions: silc_server_send_remove_channel_user and
756 silc_server_remove_channel_user into server.[ch].
758 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
759 lib/silccore/silcpacket.h. However, they are not implemented
762 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Fixed joining to a channel and sending channel messages
765 between server and router. The channel message sending should
766 now work inside a cell.
768 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Fixed the private message sending between server and router.
771 The private message sending should now work inside a cell.
773 * Added silc_server_replace_id into server.[ch] to replace
774 existing ID in the SILC network.
776 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
777 and silc_idlist_replace_server_id into idlist.[ch] in server.
779 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Fixed the server to server connections. Server can again now
782 connect to router. Router to router connections probably does
785 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Added dynamic protocol registering support. Now protocols can
788 registered and unregistered on the fly. Patch by cras.
790 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
792 * Added lib/contrib directory to hold routines that some platforms
793 don't have but are needed by SILC.
795 * Added getopt.c, getopt1.c and getopt.h from GNU C library
796 into lin/contrib to provide getopt() and getopt_long() for
797 those who don't have it.
799 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Added AWAY command to client. When away message is set and
802 client receives a private message packet the client automatically
803 replies to the sender with the away message.
805 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
806 bug seemed to be the cause of recent problems when compiling
809 * Added version detection support to SKE protocol specification
810 and added the new changes to the SKE implementation as well.
811 There were other minor changes in the SKE protocol as well.
813 Many changes in lib/silcske/silcske.[ch] and in
814 lib/silcske/payload.[ch].
816 * Added ^U functionality, clear input line. Patch from cras.
818 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
820 * Mainly small bugfixes on core library. Fixed some debugging
821 logging and buffer overflow in silclog.c.
823 * Updated config.sub and config.guess on the distribution tree.
825 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Added command lagging support in server. Client may execute
828 commands now only once in two seconds.
830 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
832 * Optimized packet reception. MAC computation and checking is now
833 also more optimized. A lot previously duplicated code is now
834 used as generic by both client and server.
836 * Fixed key pair generation in clientutil.c
838 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Added into lib/silccore/silcbufutil.[ch] new function;
843 * Moved generic packet sending/encryption functions to
844 lib/silccore/silcpacket.[ch] from client and server. Some
845 rewriting of the functions.
847 * Moved all generic packet reception/decryption functions to
848 lib/silccore/silcpacket.[ch] from client and server. The
849 packet processing is now much cleaner in both client and server.
850 These were major changes in both client and server.
852 * Created many common functions in server to do packet sending.
853 Previously code were duplicated a lot, this has been removed
856 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Rewrote major parts of the ID cache system. Don't know
859 whether it is better now or not but at least the API is more
862 * Major rewrite on ID cache stuff on client because of the ID
863 cache API changes. Added idlist.c to client.
865 * Also major rewrite on ID cache stuff on server as well.
866 Major rewrite of idlist.[ch]. SilcXXXList's are now named
867 SilcXXXEntry's. We won't keep anymore idlist specific pointers
868 in hand, instead they are all put into the ID cache system now.
869 All server_idlist_* routines uses ID cache now instead of
870 traversing its own lists (those lists does not exist anymore).
871 SilcIDList though still exists. Also, SilcXXXEntry's are
874 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Finally made the SKE implementation compliant to the protocol
877 specification. All mp integers are now binary encoded as
878 opposed being HEX encoded.
880 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
883 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
884 functions: silc_[encode/decode]_pem. Also added function
885 silc_encode_pem_file to PEM encode with newlines ('\n') for
888 * SILC public keys are now encoded either PEM or binary. Same
889 option is for private keys as well. By default private keys
890 are binary encoded and public keys PEM encoded. Silly HEX
891 encoding were removed.
893 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
894 function to create fingerprints.
896 * Fixed a bug in SHA1; does not change the original data anymore.
898 * Partly implemented INFO command on client and server side.
899 Fixed CLEAR command. Changes to SERVER command; show current
900 server(s) when giving command without arguments. Added
901 VERSION command to client.
903 * Added check to server that unregistered connections cannot
904 execute commands (unless it is specificly allowed).
906 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
908 * Fixed screen refresh.
910 * Fixed channel joining bug from client. On some circumstances
911 client tried to join to a channel it had already joined.
913 * Added public key verification process into client's protocol.c.
914 The client now verifies the public key from user and saves
915 it into ~./silc/serverkeys/ directory.
917 Added into: clientutil.[ch]: silc_client_verify_server_key.
919 * Changed SKE protocol's silc_ske_initiator_finish function
920 to accept callback function that verifies the received public
921 key. Removed old silc_ske_verify_public_key function.
923 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
926 silc_pkcs_private_key[_data]_set.
928 * Made the password and public authentication more cleaner in
931 * Removed historic and obsolete protocol `channel_auth' from
932 both client and server.
934 * Removed wrong way of sending command status messages from
935 server to client in server's command.c. The old way violated
936 protocol specification.
938 Changes to silccore/silccommand.[ch]: removed
939 silc_command_encode_status_payload -> not needed anymore,
940 changed silc_command_encode_payload_va to accept extra
941 argument on variable argument list. The argument type must
942 now be provided to the function. Also, added new function:
943 silc_command_encode_reply_payload_va which is same as
944 normal command_encode_payload_va except command status type
945 is provided as extra argument.
947 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Added ~./silc directory handling. The directory includes the
950 public and private keys for the client.
952 Added silc_client_check_silc_dir, silc_client_create_identifier
953 and silc_client_load_keys.
955 * Implemented SILC protocol compliant public key. Added public
956 and private key saving to and loading from files.
958 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
959 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
960 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
961 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
962 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
964 Implemented: silc_pkcs_save_[public/private]_key[_data] and
965 silc_pkcs_load_[public/private]_key.
967 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
969 * Added silc_server_get_route (route.[ch]) to get connection
970 data for the fastest route for given ID.
972 * Implemented INVITE command on client and server. The command
973 were re-defined in the SILC Protocol Specification and the
974 implementation now complies with the specification.
976 * Implemented PING command on client and server.
978 * Implemented NAMES command on client and server. The server side
979 supports currently only normal server not router server yet.
980 Some changes to NAMES definition in SILC protocol specification.
982 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Implemented LEAVE command on client and server.
986 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
987 again. This change was made to the protocol as well. Server
988 should not violate the protocol specification anymore.
990 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
993 was tested. SOCKS4 was not but should work anyway.
