1 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4 packet_receive.[ch] to separate packet sending and receiving
5 routines. The server.[ch] now includes everything else including
6 actual packet processing (writing and reading data) and other
9 Renamed silc_server_private_message_send_internal to
10 silc_server_send_private_message. The routine is still though
11 used only to relay private messages as server does not send
12 private messages itself.
14 Renamed silc_server_new_channel to silc_server_create_new_channel
15 and added new function sicl_server_new_channel that handles the
16 incoming New Channel packet. Added also new sending function
17 silc_server_send_new_channel to send New Channel Payload.
19 * Added new function silc_server_notify to process incoming notify
20 packet to the server/router. Server may then relay the notify
23 * Added new function silc_server_new_channel_user to process incoming
24 New Channel User packet. Router will redistribute the packet and
25 send JOIN notify to its local clients and locally connected servers
26 if needed. Normal server will send JOIN notify to its local client
27 on same channel when received this packet. Added also corresponding
28 sending function silc_server_send_new_channel_user to sent the
31 * Added boolean route argument to send_notif_to_channel and
32 packet_send_to_channel functions to attempt to route the packet
33 if it is TRUE and send only locally if it is FALSE.
35 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
37 * silc_server_replace_id now broadcasts the received replace ID
38 packet if it is not broadcast packet already. The router must
39 broadcast to inform other routers about changed ID.
41 * Added backpointer to server's router into SilcServer context in
42 silcd/server_internal.h.
44 * Fixed silc_server_packet_broadcast to send correct broadcast
47 * The channel key is now distributed to the local client as soon
48 as it is received from the router (in router environment) so that
49 no other packet may be sent for the channel until client has
52 * silc_server_remove_channel_user now broadcasts the received
53 Remove Channel User packet if it is not broadcast packet already.
54 The router must broadcast to inform other routers about removed
57 * Added users field into SilcPacketContext that is a reference count
58 of the context. One can increase the reference count by calling
59 silc_packet_context_dup which is now changed to just increase the
60 reference count instead of duplicating the data. The reference
61 count is decresed by calling silc_packet_context_free that will
62 free the data after the reference count hits zero.
64 For now on the packet context and everything allocated into it
65 (including the raw packet from network) must be freed by calling
66 the new silc_packet_context_free function. Added also new function
67 silc_packet_context_alloc that must be used now to allocate the
68 context. This also means that if a routine is asynchronous from
69 silc_[client/server]_packet_parse_type the packet context must
70 be duplicated by calling silc_packet_context_dup. Otherwise it
71 gets free'd after silc_[client/server]_packet_parse_type returns.
72 Also, one must remember that if packet is duplicated then its
73 reference count must be decresed by calling the free function as
74 many times as it was duplicated.
76 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
77 from both client and server.
79 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Made joining to a channel working in router environment.
83 * Cleaned up JOIN command on server side and create function
84 silc_server_command_join_channel internal routine to make the
87 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
89 * Changed silc_command_pending list to SilcDList. Also, added
90 `ident' field to SilcServerCommandPending structure to identify
91 the reply and to call correct callback.
93 Added silc_server_command_pending_check function to replace the
94 corresnponding macro. The silc_command_pending list is not
97 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
98 to set identifier to previously allocated Command Payload. It
99 is used to set identifier for command when resending Command
102 * Added silc_command_payload_encode_payload to encode Command
103 Payload buffer from SilcCommandPayload structure.
105 * Added silc_argument_payload_encode_payload to encode Argument
106 payload buffer from SilcArgumentPayload structure.
108 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
110 * Changed WHOIS command to support router connection on server side.
111 The whois request is always sent to router unless the server is
112 standalone server. After server has received the reply from the
113 router will it send the reply to the client.
115 * Added silc_server_packet_broadcast into silcd/server.[ch] to
116 broadcast received broadcast packet. The function is used only
117 by router. The broadcast packet is always sent to the router's
120 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
121 render given ID to printable string, for log files for example.
123 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
125 * Made basic router to router connections working. At least they
126 can now connect to each other but nothing really works the way
127 they are supposed - yet.
129 * Added new initiator token to RouterConnection configuration
130 file in silcd/serverconfig.[ch]. It is used to tell whether we
131 are the initiator to the remote router or whether we'll expect
132 the other end to connect.
134 * Moved registering of listener task to silc_server_init, hence
135 the server starts listenning as soon as it is run, even if it
136 does not have connections to other routers. Let's see how well
139 * Changed default connection retry timeouts for more suitable in
142 * Removed cipher and such arguments from silc_idlist_add_client
143 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
144 Added new function silc_idlist_add_data to add the keys and stuff
147 * Added SilcIDListData structure and added it to SilcClientEntry
148 and SilcServerEntry as their first field in the structure. This
149 way we can explicitly cast the ID entries to the SilcIDListData
150 structure and get common data for the entries. In past, we had
151 to first check what type of connection it is and then cast it to
152 correct ID entry type. Now, we can directly cast the opaque
153 pointer to the SilcIDListData (no matter what ID entry it actually
154 is) and get the data needed.
156 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Wow, found a bug in scheduler. The scheduler uninitialized itself
159 in some circumstances even if threre were timeout tasks, though not
160 IO tasks, but tasks anyway. Now fixed.
162 * Defined SilcServerConnection structure to hold connection specific
163 stuff about directly connected servers and routers. The definition
164 is currently in silcd/server_internal.h. I thought about having
165 a bit more important role fro this struct but for now it is used
166 only when connecting to other server (or router actually).
168 * Added connecting retry support in server when connecting to
169 router(s). The retry feature implement exponential backoff
170 algorithm. Also, added SilcServerParams structure to hold default
171 parameters for server. For now, it include these retry settings
172 and are hard coded. After server is moded to be as Silc Server
173 Library this structure will be more important.
175 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
177 * Changed client librarys channel->clients table to SilcList and
178 changed code accordingly.
180 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Changed client's channel table to SilcList and changed code
183 accordingly. Also changed SilcChannelClientEntry to include back-
184 pointer to the channel so that client entry can use that structure
185 as list as well and we have fast cross-reference to the channel.
186 This change dramatically decreased the complexity of channel
187 handling with client entry and vice versa (removed one extra
188 loop when searching for channel entry from many functions).
190 * Changed server->sim from table to SilcDList and changed code
193 * NAMES command can now be used from user interface. It will show
194 the user list on the channel, neatly.
196 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
197 Code now saves realname of the user if it becomes available.
199 * Renamed configure.in to configure.in.pre and made ./prepare
200 script to automatically add correct version string to
201 configure.in which it creates from configure.in.pre.
203 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * NAMES command reply now shows users mode with the nickname when
208 * Moved silc_client_ch[u]mode[_char] functions from
209 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
210 place sucks, they are utility functions and should be in some
213 * Fixed some unsigned int's to unsigned short's. Patch by cras.
215 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
218 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
222 * Added TRQ (efficient deque and list library) into lib/trq. This is
223 a very good list library that is currently used in the SILC. Defined
224 SilcList API over the library because I didn't like the API very
225 much. See lib/trq/silclist.h for the API and examples of how to
226 use the API. Fixed various places in the code to use the new
227 SilcList API. The SilcList is meant for lists that has a structure
228 already defined as a list. It is not suitable to add just some
229 context to the list (in TRQ, the context is the list actually).
231 So, I defined SilcDList that can be used for the purpose where
232 predefined list structure does not exit. This can be used as
233 such list. Now some context just can be added to the SilcDList.
234 Currently this list is not used in the SILC just yet, though there
235 are a lot places where this can replace dynamically allocated
236 tables and I will fix these places, later, to use SilcDList.
237 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
238 and use TRQ internally).
240 Also fixed some annoying warning messages that the original TRQ
241 code generated. Also minor changes to TRQ's Makefile.in.
243 * Added support for querying by Client ID to both WHOIS and
244 IDENTIFY commands into server, as required by the protocol.
246 * Removed method function pointers from SilcBuffer structure. They
247 weren't used to anything and just increased the context size for
248 no good reason. This change also made silc_buffer_alloc and
249 silc_buffer_free functions inline functions.
251 * Disabled command flooding detection support until it's fixed so
252 that it accepts commands in but does not execute them more than once
255 * Added silc_net_localhost(), to return local hostname, into
256 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
257 that must be initialized before calling silc_client_init.
259 * Added new function: silc_server_send_notify_on_channels to send
260 notify messages to all channels client has joined. It is assured
261 that the message is sent only once per client.
263 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
264 lib/silcutil/silcutil.[ch] as silc_format function. The new
265 function is generic and is used by server as well, not only by
266 the logging routines.
268 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
269 the provided version string was not acceptable. Added new function:
270 silc_ske_check_version into lib/silcske/silcske.h. The function
271 must be implemented by the application (client or server) and it
272 does not reside in the SKE library. The function checks the version
273 string remote end sent.
275 * Added back pointers (to opaque context and to SilcSocketConnection)
276 into SilcPacketContext structure into lib/silccore/silcpacket.h.
278 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
279 duplicate packet context structure.
281 * Changed `notify' client operation to send same arguments as client
282 receives from server except for ID's. ID's are mapped to correct
283 ID entry and that is returned. Also, if channel entry is not sent
284 by server but the notify is for channel the channel entry is sent
285 to application (otherwise application doesn't know that it is for
286 channel (library gets it from packet's Destination ID)).
288 * Added silc_client_remove_from_channels into client library to
289 remove a client from all channels it has joined to. Used when
290 received SIGNOFF notify from server. Added also new function
291 silc_client_replace_from_channels to replace old ID entry with
292 new ID entry on all channels. Used when received NICK_CHANGE
295 * Fixed ID Cache list handling in silc_idlist_get_client in
296 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
297 to get (or query) client by ID.
301 * Added connection authentication status message defined by the
302 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
303 support for these into the code in client and server side.
305 * Added generic function silc_client_send_command to send any command
306 with variable argument list. Application should use this function
307 to send commands if the command functions provided by the library
308 does not suite for the application's user interface needs.
310 * Added new `failure' client operation. Application is notified about
311 received failure packet if client is executing a protocol. In this
312 case the protocol's execution has failed.
314 * Added SKE's end notify to send the SKE_SUCCESS notify message that
315 is required by the protocol.
317 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
318 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
321 * Added status flag to SilcSKE object to indicate realtime status
324 * Application receives now exactly same command reply arguments as
325 the library receives from server. However, if ID is received the
326 corresponding ID entry is returned to the application (eg. Client
327 ID is mapped to correct SilcClientEntry entry and that is returned).
328 Changed command_reply client operation due to this change.
330 * Changed all ID's in commands and in command replys as ID Payloads.
331 Change affected both client and server side codes.
333 All ID's sent in SILC network (with execption of ID's in SILC
334 Packet header) are sent in ID Payload to support variable length
337 * Server now notifies nick changes and notifies all clients on
338 the channels about the new nickname (about the new Client ID,
341 * Implemented CMODE command to change channel modes. Supports all
342 channel modes defined by the protocol specs except ban and invite
343 lists. (Also, private channel key mode is supported but support for
344 setting private channel key in client is missing, thus, this mode
345 has no effect on client side (except that server requires that the
346 client uses private channel key and normal channel traffic does not
349 Also, invite mode works per se, but INVITE command does not work
350 yet correctly, so you can set channel as invite only channel but
351 inviting clients to the channel does not work (it is yet to be
352 thought what's the best way to do it).
354 * Added new command SILC_COMMAND_CUMODE to change user mode on the
355 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
356 Implemented CUMODE command to change user's mode on the channel.
357 Supports all modes defined by the protocol specs.
359 * Added NAMES command reply to return users modes on the channel.
361 * Removed unnecessary and slow ciphers from lib/silccrypt.
363 * Set SO_KEEPALIVE option to connection sockets by default.
365 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
367 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
368 redefined the Notify Payload into protocol specs.
370 * Added silc_id_payload_parse_id to get ID directly from raw
373 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
376 accept searching by Client ID as well.
378 * Added support for LEAVE and SIGNOFF notify types in client library.
380 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
381 to parse ID Payload from raw data.
383 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Added flags parameter into silc_ske_assemble_security_properties
386 function in lib/silcske/silcske.[ch].
388 * Changed notify client operation to fit better for notify messages
389 sent by server. The notify payload received from server is now
390 passed to the application (after parsing it to SilcNotifyPayload).
391 It is application's responsibility to retrieve the arguments
392 from the payload and show the message the way it wants. The message
393 sent by server is implementation specific.
395 * Changed public keys to comply with the protocol specification.
396 Old public keys are not supported anymore and are not compatible.
398 * Removed nickname from Channel Payload as the latest draft removed
399 it. The client must resolve the nickname from the NAMES command
400 reply received when it joined the channel.
402 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
404 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Fixed some errors in protocol specification drafts.
408 * Created lib/silccore/silcnotify.c to implement Notify Payload
409 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
410 generic payloads described by protocol specifications. The file
411 includes implementations for ID Payload and Argument Payload.
413 * Changed Command Payload implementation to use the new Argument
414 Payload. Changed command_xxxx_payload to command_payload_xxxx
415 to comply with SILC coding conventions.
417 * Added suppport for Argument Payload handling in Notify Payload
418 implementation as protocol requires it. Added the new support
419 into server and client lib as well.
421 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
423 * Added support for multiple nicknames on same channel. [n] is
424 added locally to the nickname if there are more than one same
425 nicknames on the channel.
427 * Server now sends all nicknames that matched WHOIS request.
428 Client also shows the list received from server.
430 * Added TOPIC command to client side. User can now set and show
431 current topic on channel.
433 * Added MOTD command to client and server. Also, server sends the
434 motd when client connects to the server.
436 * Changed version strings to comply ISO 8601.
438 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Fixed protocol error handling in client library. It should now
441 cope even if the SKE fails for some reason.
443 * Made new protocol specification drafts for submitting to IETF.
445 * Implemented TOPIC command to server in silcd/command.c.
447 * Added two new notify types into lib/silccore/silcnotify.h:
448 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
449 notify nickname change and topic setting/change on a channel.
451 * API change of command_reply operation in client library. The
452 application gets now the status type received from server as well.
454 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Removed the function just added to lib/silcutil/silcschedule.[ch].
458 * Cras fixed and optimized the packet handling even further and
459 it should work now. Minor change to the prototype of function
460 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
462 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Added new function into lib/silcutil/silcschedule.[ch]:
465 silc_schedule_with_fd to select() a specified fd. The function
466 returns after timeout expires or data arrives or goes. The
467 function is used by packet routines to wait that all data is
468 received from network.
470 * Fixed data reading from network in lib/silccore/silcpacket.c.
471 The code now assures that all data is read from the fd and then
472 continues packet processing. This was a bug fix since the code
473 used to drop some data in some circumstances.
475 * Added new function into lib/silcclient/client.[ch]:
476 silc_client_start_key_exchange to start key exchange after
477 connection has been established to server. The code internally
478 now uses this funtion but its main purpose was to provide it
479 for applications that perform their own connecting. After
480 application has created a connection it merely calls this
481 function to start the key exchange between client and server.
482 The library takes care of everything else after that.
484 Updated also lib/silcclient/README to explain the usage of
487 * Do not send to application information that connection has
488 been established. Application gets notified it by connect
491 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Applied cras's patch to add silc_schedule_one function. The
494 function runs scheduler once and returns.
496 * Fixed the scheduler after cras messed it up. The timeout
497 handling works now as it's supposed to work.
499 * Added into lib/silccore/ silcnotify.h to include notify
500 message types support. Changed silc_server_send_notify*
501 functions, in server.[ch], to support those new notify types.
502 Added the support for the notify types into client library,
503 as well. Added new notify client operation into ops.h in
506 * Changed silc_server_packet_send_to_channel to send normal
507 packets instead of just channel message packets. The function
508 is now used to send the notify packets to channels. It is not
509 used to send channel message packets anymore, as server never
512 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
513 va_arg()s as it seems to require it nowadays. I guess, if SILC
514 is compiled with older va_arg() the new code should work anyway.
516 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * Splitted core library. Core library (lib/silccore) includes
519 now only SILC protocol specific core (and common) components.
520 Created new utility library (lib/silcutil) that includes more
521 generic purpose stuff. The stuff for util library was taken
522 from the old core library. This was minor and easy split.
524 * Created SILC Client Library (lib/silcclient) that includes
525 implementation of the SILC client without user interface. This
526 was major move from silc/ directory. The code has been changed
527 so that it is transparent towards the user interface. The
528 silc/ directory includes now the same user interface as before
529 and it uses the new client library. Read lib/silcclient/README.
530 Basicly, the client library performs everything else related
531 to SILC except user interface handling. Also, configuration
532 files are considered to be part of user interface and library
533 does not handle them.
535 This change also changed a lot of structures, function naming etc.
536 Most important change was that SilcClientWindow object was
537 renamed to SilcClientConnection in the client library. Created
538 also new file lib/silcclient/ops.h. Also added new files
539 silc/local_command.[ch] and silc/client_ops.[ch].
541 All these changes were made to make it easier for user interface
542 designers to create what ever user interface for the SILC client
545 It is also expected that the server will be moved to lib
546 directory as well and SILC Server Library will be created;
547 sometimes in the future.
549 * Removed Local commands from lib/silccore/silccommand.h as
550 they are application specific and new client library does not
551 handle any of those anymore.
553 * Several functions moved to lib/silcutil/silcutilc.[ch] from
554 old client implementation in silc/.
556 * Added support for callback functions in SILC_LOG_* macros.
557 Application can now set its own callbacks that will be called
558 instead of using the default functions that will always print
559 the debug messages to stderr (or stdout). Also, debugging can
560 now be disabled by setting silc_debug to FALSE and re-enabled by
561 setting it to TRUE. Note, that logging will still work even
562 if debugging is disabled.
564 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
565 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
566 silc_log_reset_debug_callbacks.
568 * To enable debugging in silc client one must give now -d
569 option on command line.
571 * Changed silc_schedule_init to automatically allocate task queues
572 if they are not allocated before calling it.
574 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * Added GMP 3.1 into math library.
578 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
580 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
581 a channel in SILC network. The packet is used by servers and
582 routers to notify other routers that user has left a channel.
583 This little feature was missing until now. Added the feature
584 to protocol specification as well.
586 Added functions: silc_server_send_remove_channel_user and
587 silc_server_remove_channel_user into server.[ch].
589 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
590 lib/silccore/silcpacket.h. However, they are not implemented
593 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Fixed joining to a channel and sending channel messages
596 between server and router. The channel message sending should
597 now work inside a cell.
599 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Fixed the private message sending between server and router.
602 The private message sending should now work inside a cell.
604 * Added silc_server_replace_id into server.[ch] to replace
605 existing ID in the SILC network.
607 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
608 and silc_idlist_replace_server_id into idlist.[ch] in server.
610 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
612 * Fixed the server to server connections. Server can again now
613 connect to router. Router to router connections probably does
616 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Added dynamic protocol registering support. Now protocols can
619 registered and unregistered on the fly. Patch by cras.
621 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Added lib/contrib directory to hold routines that some platforms
624 don't have but are needed by SILC.
626 * Added getopt.c, getopt1.c and getopt.h from GNU C library
627 into lin/contrib to provide getopt() and getopt_long() for
628 those who don't have it.
630 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
632 * Added AWAY command to client. When away message is set and
633 client receives a private message packet the client automatically
634 replies to the sender with the away message.
636 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
637 bug seemed to be the cause of recent problems when compiling
640 * Added version detection support to SKE protocol specification
641 and added the new changes to the SKE implementation as well.
642 There were other minor changes in the SKE protocol as well.
644 Many changes in lib/silcske/silcske.[ch] and in
645 lib/silcske/payload.[ch].
647 * Added ^U functionality, clear input line. Patch from cras.
649 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Mainly small bugfixes on core library. Fixed some debugging
652 logging and buffer overflow in silclog.c.
654 * Updated config.sub and config.guess on the distribution tree.
656 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
658 * Added command lagging support in server. Client may execute
659 commands now only once in two seconds.
661 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Optimized packet reception. MAC computation and checking is now
664 also more optimized. A lot previously duplicated code is now
665 used as generic by both client and server.
667 * Fixed key pair generation in clientutil.c
669 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Added into lib/silccore/silcbufutil.[ch] new function;
674 * Moved generic packet sending/encryption functions to
675 lib/silccore/silcpacket.[ch] from client and server. Some
676 rewriting of the functions.
678 * Moved all generic packet reception/decryption functions to
679 lib/silccore/silcpacket.[ch] from client and server. The
680 packet processing is now much cleaner in both client and server.
681 These were major changes in both client and server.
683 * Created many common functions in server to do packet sending.
684 Previously code were duplicated a lot, this has been removed
687 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Rewrote major parts of the ID cache system. Don't know
690 whether it is better now or not but at least the API is more
693 * Major rewrite on ID cache stuff on client because of the ID
694 cache API changes. Added idlist.c to client.
696 * Also major rewrite on ID cache stuff on server as well.
697 Major rewrite of idlist.[ch]. SilcXXXList's are now named
698 SilcXXXEntry's. We won't keep anymore idlist specific pointers
699 in hand, instead they are all put into the ID cache system now.
700 All server_idlist_* routines uses ID cache now instead of
701 traversing its own lists (those lists does not exist anymore).
702 SilcIDList though still exists. Also, SilcXXXEntry's are
705 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Finally made the SKE implementation compliant to the protocol
708 specification. All mp integers are now binary encoded as
709 opposed being HEX encoded.
711 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
714 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
715 functions: silc_[encode/decode]_pem. Also added function
716 silc_encode_pem_file to PEM encode with newlines ('\n') for
719 * SILC public keys are now encoded either PEM or binary. Same
720 option is for private keys as well. By default private keys
721 are binary encoded and public keys PEM encoded. Silly HEX
722 encoding were removed.
724 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
725 function to create fingerprints.
727 * Fixed a bug in SHA1; does not change the original data anymore.
729 * Partly implemented INFO command on client and server side.
730 Fixed CLEAR command. Changes to SERVER command; show current
731 server(s) when giving command without arguments. Added
732 VERSION command to client.
734 * Added check to server that unregistered connections cannot
735 execute commands (unless it is specificly allowed).
737 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
739 * Fixed screen refresh.
741 * Fixed channel joining bug from client. On some circumstances
742 client tried to join to a channel it had already joined.
744 * Added public key verification process into client's protocol.c.
745 The client now verifies the public key from user and saves
746 it into ~./silc/serverkeys/ directory.
748 Added into: clientutil.[ch]: silc_client_verify_server_key.
750 * Changed SKE protocol's silc_ske_initiator_finish function
751 to accept callback function that verifies the received public
752 key. Removed old silc_ske_verify_public_key function.
754 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
756 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
757 silc_pkcs_private_key[_data]_set.
759 * Made the password and public authentication more cleaner in
762 * Removed historic and obsolete protocol `channel_auth' from
763 both client and server.
765 * Removed wrong way of sending command status messages from
766 server to client in server's command.c. The old way violated
767 protocol specification.
769 Changes to silccore/silccommand.[ch]: removed
770 silc_command_encode_status_payload -> not needed anymore,
771 changed silc_command_encode_payload_va to accept extra
772 argument on variable argument list. The argument type must
773 now be provided to the function. Also, added new function:
774 silc_command_encode_reply_payload_va which is same as
775 normal command_encode_payload_va except command status type
776 is provided as extra argument.
778 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Added ~./silc directory handling. The directory includes the
781 public and private keys for the client.
783 Added silc_client_check_silc_dir, silc_client_create_identifier
784 and silc_client_load_keys.
786 * Implemented SILC protocol compliant public key. Added public
787 and private key saving to and loading from files.
789 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
790 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
791 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
792 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
793 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
795 Implemented: silc_pkcs_save_[public/private]_key[_data] and
796 silc_pkcs_load_[public/private]_key.
798 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Added silc_server_get_route (route.[ch]) to get connection
801 data for the fastest route for given ID.
803 * Implemented INVITE command on client and server. The command
804 were re-defined in the SILC Protocol Specification and the
805 implementation now complies with the specification.
807 * Implemented PING command on client and server.
809 * Implemented NAMES command on client and server. The server side
810 supports currently only normal server not router server yet.
811 Some changes to NAMES definition in SILC protocol specification.
813 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Implemented LEAVE command on client and server.
817 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
818 again. This change was made to the protocol as well. Server
819 should not violate the protocol specification anymore.
821 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
823 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
824 was tested. SOCKS4 was not but should work anyway.
