3 * Fixed a channel user mode bug when joining to a channel server gave
4 everybody channel founder rights, oops.
6 * We mark ourselves as the router of the incoming server connection
7 if we are router ourselves. This way we can check in some packet
8 sending functions whether it is locally connected server. For
9 incoming router connections we put NULL.
11 * For router sending packets locally means now always sending the
12 packet cell wide; to local clients and local servers. For normal
13 server sending packet locally means sending it to only local
16 * Fixed the JOIN command to really work in router environment. If the
17 channel is created it is always created by the router. Router is
18 also responsible of making the initial joining to the channel,
19 sending JOIN notify to the sending server and distributing
20 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
21 does not exist server doesn't do anything else but forward the
22 command to the router which performs everything.
24 * Added silc_server_send_channel_key function to send the Channel Key
27 * Added silc_server_create_channel_key to create new channel key. The
28 channel key is now re-generated everytime someone joins or leaves
29 a channel, as protocol dictates. Note: channel->key_len is the
32 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
34 * Splitted server.[ch] finally. Created now packet_send.[ch] and
35 packet_receive.[ch] to separate packet sending and receiving
36 routines. The server.[ch] now includes everything else including
37 actual packet processing (writing and reading data) and other
40 Renamed silc_server_private_message_send_internal to
41 silc_server_send_private_message. The routine is still though
42 used only to relay private messages as server does not send
43 private messages itself.
45 Renamed silc_server_new_channel to silc_server_create_new_channel
46 and added new function sicl_server_new_channel that handles the
47 incoming New Channel packet. Added also new sending function
48 silc_server_send_new_channel to send New Channel Payload.
50 * Added new function silc_server_notify to process incoming notify
51 packet to the server/router. Server may then relay the notify
54 * Added new function silc_server_new_channel_user to process incoming
55 New Channel User packet. Router will redistribute the packet and
56 send JOIN notify to its local clients and locally connected servers
57 if needed. Normal server will send JOIN notify to its local client
58 on same channel when received this packet. Added also corresponding
59 sending function silc_server_send_new_channel_user to sent the
62 * Added boolean route argument to send_notif_to_channel and
63 packet_send_to_channel functions to attempt to route the packet
64 if it is TRUE and send only locally if it is FALSE.
66 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
68 * silc_server_replace_id now broadcasts the received replace ID
69 packet if it is not broadcast packet already. The router must
70 broadcast to inform other routers about changed ID.
72 * Added backpointer to server's router into SilcServer context in
73 silcd/server_internal.h.
75 * Fixed silc_server_packet_broadcast to send correct broadcast
78 * The channel key is now distributed to the local client as soon
79 as it is received from the router (in router environment) so that
80 no other packet may be sent for the channel until client has
83 * silc_server_remove_channel_user now broadcasts the received
84 Remove Channel User packet if it is not broadcast packet already.
85 The router must broadcast to inform other routers about removed
88 * Added users field into SilcPacketContext that is a reference count
89 of the context. One can increase the reference count by calling
90 silc_packet_context_dup which is now changed to just increase the
91 reference count instead of duplicating the data. The reference
92 count is decresed by calling silc_packet_context_free that will
93 free the data after the reference count hits zero.
95 For now on the packet context and everything allocated into it
96 (including the raw packet from network) must be freed by calling
97 the new silc_packet_context_free function. Added also new function
98 silc_packet_context_alloc that must be used now to allocate the
99 context. This also means that if a routine is asynchronous from
100 silc_[client/server]_packet_parse_type the packet context must
101 be duplicated by calling silc_packet_context_dup. Otherwise it
102 gets free'd after silc_[client/server]_packet_parse_type returns.
103 Also, one must remember that if packet is duplicated then its
104 reference count must be decresed by calling the free function as
105 many times as it was duplicated.
107 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
108 from both client and server.
110 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
112 * Made joining to a channel working in router environment.
114 * Cleaned up JOIN command on server side and create function
115 silc_server_command_join_channel internal routine to make the
118 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Changed silc_command_pending list to SilcDList. Also, added
121 `ident' field to SilcServerCommandPending structure to identify
122 the reply and to call correct callback.
124 Added silc_server_command_pending_check function to replace the
125 corresnponding macro. The silc_command_pending list is not
128 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
129 to set identifier to previously allocated Command Payload. It
130 is used to set identifier for command when resending Command
133 * Added silc_command_payload_encode_payload to encode Command
134 Payload buffer from SilcCommandPayload structure.
136 * Added silc_argument_payload_encode_payload to encode Argument
137 payload buffer from SilcArgumentPayload structure.
139 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Changed WHOIS command to support router connection on server side.
142 The whois request is always sent to router unless the server is
143 standalone server. After server has received the reply from the
144 router will it send the reply to the client.
146 * Added silc_server_packet_broadcast into silcd/server.[ch] to
147 broadcast received broadcast packet. The function is used only
148 by router. The broadcast packet is always sent to the router's
151 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
152 render given ID to printable string, for log files for example.
154 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
156 * Made basic router to router connections working. At least they
157 can now connect to each other but nothing really works the way
158 they are supposed - yet.
160 * Added new initiator token to RouterConnection configuration
161 file in silcd/serverconfig.[ch]. It is used to tell whether we
162 are the initiator to the remote router or whether we'll expect
163 the other end to connect.
165 * Moved registering of listener task to silc_server_init, hence
166 the server starts listenning as soon as it is run, even if it
167 does not have connections to other routers. Let's see how well
170 * Changed default connection retry timeouts for more suitable in
173 * Removed cipher and such arguments from silc_idlist_add_client
174 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
175 Added new function silc_idlist_add_data to add the keys and stuff
178 * Added SilcIDListData structure and added it to SilcClientEntry
179 and SilcServerEntry as their first field in the structure. This
180 way we can explicitly cast the ID entries to the SilcIDListData
181 structure and get common data for the entries. In past, we had
182 to first check what type of connection it is and then cast it to
183 correct ID entry type. Now, we can directly cast the opaque
184 pointer to the SilcIDListData (no matter what ID entry it actually
185 is) and get the data needed.
187 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Wow, found a bug in scheduler. The scheduler uninitialized itself
190 in some circumstances even if threre were timeout tasks, though not
191 IO tasks, but tasks anyway. Now fixed.
193 * Defined SilcServerConnection structure to hold connection specific
194 stuff about directly connected servers and routers. The definition
195 is currently in silcd/server_internal.h. I thought about having
196 a bit more important role fro this struct but for now it is used
197 only when connecting to other server (or router actually).
199 * Added connecting retry support in server when connecting to
200 router(s). The retry feature implement exponential backoff
201 algorithm. Also, added SilcServerParams structure to hold default
202 parameters for server. For now, it include these retry settings
203 and are hard coded. After server is moded to be as Silc Server
204 Library this structure will be more important.
206 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Changed client librarys channel->clients table to SilcList and
209 changed code accordingly.
211 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Changed client's channel table to SilcList and changed code
214 accordingly. Also changed SilcChannelClientEntry to include back-
215 pointer to the channel so that client entry can use that structure
216 as list as well and we have fast cross-reference to the channel.
217 This change dramatically decreased the complexity of channel
218 handling with client entry and vice versa (removed one extra
219 loop when searching for channel entry from many functions).
221 * Changed server->sim from table to SilcDList and changed code
224 * NAMES command can now be used from user interface. It will show
225 the user list on the channel, neatly.
227 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
228 Code now saves realname of the user if it becomes available.
230 * Renamed configure.in to configure.in.pre and made ./prepare
231 script to automatically add correct version string to
232 configure.in which it creates from configure.in.pre.
234 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * NAMES command reply now shows users mode with the nickname when
239 * Moved silc_client_ch[u]mode[_char] functions from
240 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
241 place sucks, they are utility functions and should be in some
244 * Fixed some unsigned int's to unsigned short's. Patch by cras.
246 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
249 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Added TRQ (efficient deque and list library) into lib/trq. This is
254 a very good list library that is currently used in the SILC. Defined
255 SilcList API over the library because I didn't like the API very
256 much. See lib/trq/silclist.h for the API and examples of how to
257 use the API. Fixed various places in the code to use the new
258 SilcList API. The SilcList is meant for lists that has a structure
259 already defined as a list. It is not suitable to add just some
260 context to the list (in TRQ, the context is the list actually).
262 So, I defined SilcDList that can be used for the purpose where
263 predefined list structure does not exit. This can be used as
264 such list. Now some context just can be added to the SilcDList.
265 Currently this list is not used in the SILC just yet, though there
266 are a lot places where this can replace dynamically allocated
267 tables and I will fix these places, later, to use SilcDList.
268 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
269 and use TRQ internally).
271 Also fixed some annoying warning messages that the original TRQ
272 code generated. Also minor changes to TRQ's Makefile.in.
274 * Added support for querying by Client ID to both WHOIS and
275 IDENTIFY commands into server, as required by the protocol.
277 * Removed method function pointers from SilcBuffer structure. They
278 weren't used to anything and just increased the context size for
279 no good reason. This change also made silc_buffer_alloc and
280 silc_buffer_free functions inline functions.
282 * Disabled command flooding detection support until it's fixed so
283 that it accepts commands in but does not execute them more than once
286 * Added silc_net_localhost(), to return local hostname, into
287 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
288 that must be initialized before calling silc_client_init.
290 * Added new function: silc_server_send_notify_on_channels to send
291 notify messages to all channels client has joined. It is assured
292 that the message is sent only once per client.
294 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
295 lib/silcutil/silcutil.[ch] as silc_format function. The new
296 function is generic and is used by server as well, not only by
297 the logging routines.
299 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
300 the provided version string was not acceptable. Added new function:
301 silc_ske_check_version into lib/silcske/silcske.h. The function
302 must be implemented by the application (client or server) and it
303 does not reside in the SKE library. The function checks the version
304 string remote end sent.
306 * Added back pointers (to opaque context and to SilcSocketConnection)
307 into SilcPacketContext structure into lib/silccore/silcpacket.h.
309 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
310 duplicate packet context structure.
312 * Changed `notify' client operation to send same arguments as client
313 receives from server except for ID's. ID's are mapped to correct
314 ID entry and that is returned. Also, if channel entry is not sent
315 by server but the notify is for channel the channel entry is sent
316 to application (otherwise application doesn't know that it is for
317 channel (library gets it from packet's Destination ID)).
319 * Added silc_client_remove_from_channels into client library to
320 remove a client from all channels it has joined to. Used when
321 received SIGNOFF notify from server. Added also new function
322 silc_client_replace_from_channels to replace old ID entry with
323 new ID entry on all channels. Used when received NICK_CHANGE
326 * Fixed ID Cache list handling in silc_idlist_get_client in
327 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
328 to get (or query) client by ID.
332 * Added connection authentication status message defined by the
333 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
334 support for these into the code in client and server side.
336 * Added generic function silc_client_send_command to send any command
337 with variable argument list. Application should use this function
338 to send commands if the command functions provided by the library
339 does not suite for the application's user interface needs.
341 * Added new `failure' client operation. Application is notified about
342 received failure packet if client is executing a protocol. In this
343 case the protocol's execution has failed.
345 * Added SKE's end notify to send the SKE_SUCCESS notify message that
346 is required by the protocol.
348 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
349 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
352 * Added status flag to SilcSKE object to indicate realtime status
355 * Application receives now exactly same command reply arguments as
356 the library receives from server. However, if ID is received the
357 corresponding ID entry is returned to the application (eg. Client
358 ID is mapped to correct SilcClientEntry entry and that is returned).
359 Changed command_reply client operation due to this change.
361 * Changed all ID's in commands and in command replys as ID Payloads.
362 Change affected both client and server side codes.
364 All ID's sent in SILC network (with execption of ID's in SILC
365 Packet header) are sent in ID Payload to support variable length
368 * Server now notifies nick changes and notifies all clients on
369 the channels about the new nickname (about the new Client ID,
372 * Implemented CMODE command to change channel modes. Supports all
373 channel modes defined by the protocol specs except ban and invite
374 lists. (Also, private channel key mode is supported but support for
375 setting private channel key in client is missing, thus, this mode
376 has no effect on client side (except that server requires that the
377 client uses private channel key and normal channel traffic does not
380 Also, invite mode works per se, but INVITE command does not work
381 yet correctly, so you can set channel as invite only channel but
382 inviting clients to the channel does not work (it is yet to be
383 thought what's the best way to do it).
385 * Added new command SILC_COMMAND_CUMODE to change user mode on the
386 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
387 Implemented CUMODE command to change user's mode on the channel.
388 Supports all modes defined by the protocol specs.
390 * Added NAMES command reply to return users modes on the channel.
392 * Removed unnecessary and slow ciphers from lib/silccrypt.
394 * Set SO_KEEPALIVE option to connection sockets by default.
396 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
398 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
399 redefined the Notify Payload into protocol specs.
401 * Added silc_id_payload_parse_id to get ID directly from raw
404 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
407 accept searching by Client ID as well.
409 * Added support for LEAVE and SIGNOFF notify types in client library.
411 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
412 to parse ID Payload from raw data.
414 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Added flags parameter into silc_ske_assemble_security_properties
417 function in lib/silcske/silcske.[ch].
419 * Changed notify client operation to fit better for notify messages
420 sent by server. The notify payload received from server is now
421 passed to the application (after parsing it to SilcNotifyPayload).
422 It is application's responsibility to retrieve the arguments
423 from the payload and show the message the way it wants. The message
424 sent by server is implementation specific.
426 * Changed public keys to comply with the protocol specification.
427 Old public keys are not supported anymore and are not compatible.
429 * Removed nickname from Channel Payload as the latest draft removed
430 it. The client must resolve the nickname from the NAMES command
431 reply received when it joined the channel.
433 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
435 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Fixed some errors in protocol specification drafts.
439 * Created lib/silccore/silcnotify.c to implement Notify Payload
440 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
441 generic payloads described by protocol specifications. The file
442 includes implementations for ID Payload and Argument Payload.
444 * Changed Command Payload implementation to use the new Argument
445 Payload. Changed command_xxxx_payload to command_payload_xxxx
446 to comply with SILC coding conventions.
448 * Added suppport for Argument Payload handling in Notify Payload
449 implementation as protocol requires it. Added the new support
450 into server and client lib as well.
452 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Added support for multiple nicknames on same channel. [n] is
455 added locally to the nickname if there are more than one same
456 nicknames on the channel.
458 * Server now sends all nicknames that matched WHOIS request.
459 Client also shows the list received from server.
461 * Added TOPIC command to client side. User can now set and show
462 current topic on channel.
464 * Added MOTD command to client and server. Also, server sends the
465 motd when client connects to the server.
467 * Changed version strings to comply ISO 8601.
469 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Fixed protocol error handling in client library. It should now
472 cope even if the SKE fails for some reason.
474 * Made new protocol specification drafts for submitting to IETF.
476 * Implemented TOPIC command to server in silcd/command.c.
478 * Added two new notify types into lib/silccore/silcnotify.h:
479 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
480 notify nickname change and topic setting/change on a channel.
482 * API change of command_reply operation in client library. The
483 application gets now the status type received from server as well.
485 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * Removed the function just added to lib/silcutil/silcschedule.[ch].
489 * Cras fixed and optimized the packet handling even further and
490 it should work now. Minor change to the prototype of function
491 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
493 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
495 * Added new function into lib/silcutil/silcschedule.[ch]:
496 silc_schedule_with_fd to select() a specified fd. The function
497 returns after timeout expires or data arrives or goes. The
498 function is used by packet routines to wait that all data is
499 received from network.
501 * Fixed data reading from network in lib/silccore/silcpacket.c.
502 The code now assures that all data is read from the fd and then
503 continues packet processing. This was a bug fix since the code
504 used to drop some data in some circumstances.
506 * Added new function into lib/silcclient/client.[ch]:
507 silc_client_start_key_exchange to start key exchange after
508 connection has been established to server. The code internally
509 now uses this funtion but its main purpose was to provide it
510 for applications that perform their own connecting. After
511 application has created a connection it merely calls this
512 function to start the key exchange between client and server.
513 The library takes care of everything else after that.
515 Updated also lib/silcclient/README to explain the usage of
518 * Do not send to application information that connection has
519 been established. Application gets notified it by connect
522 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
524 * Applied cras's patch to add silc_schedule_one function. The
525 function runs scheduler once and returns.
527 * Fixed the scheduler after cras messed it up. The timeout
528 handling works now as it's supposed to work.
530 * Added into lib/silccore/ silcnotify.h to include notify
531 message types support. Changed silc_server_send_notify*
532 functions, in server.[ch], to support those new notify types.
533 Added the support for the notify types into client library,
534 as well. Added new notify client operation into ops.h in
537 * Changed silc_server_packet_send_to_channel to send normal
538 packets instead of just channel message packets. The function
539 is now used to send the notify packets to channels. It is not
540 used to send channel message packets anymore, as server never
543 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
544 va_arg()s as it seems to require it nowadays. I guess, if SILC
545 is compiled with older va_arg() the new code should work anyway.
547 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Splitted core library. Core library (lib/silccore) includes
550 now only SILC protocol specific core (and common) components.
551 Created new utility library (lib/silcutil) that includes more
552 generic purpose stuff. The stuff for util library was taken
553 from the old core library. This was minor and easy split.
555 * Created SILC Client Library (lib/silcclient) that includes
556 implementation of the SILC client without user interface. This
557 was major move from silc/ directory. The code has been changed
558 so that it is transparent towards the user interface. The
559 silc/ directory includes now the same user interface as before
560 and it uses the new client library. Read lib/silcclient/README.
561 Basicly, the client library performs everything else related
562 to SILC except user interface handling. Also, configuration
563 files are considered to be part of user interface and library
564 does not handle them.
566 This change also changed a lot of structures, function naming etc.
567 Most important change was that SilcClientWindow object was
568 renamed to SilcClientConnection in the client library. Created
569 also new file lib/silcclient/ops.h. Also added new files
570 silc/local_command.[ch] and silc/client_ops.[ch].
572 All these changes were made to make it easier for user interface
573 designers to create what ever user interface for the SILC client
576 It is also expected that the server will be moved to lib
577 directory as well and SILC Server Library will be created;
578 sometimes in the future.
580 * Removed Local commands from lib/silccore/silccommand.h as
581 they are application specific and new client library does not
582 handle any of those anymore.
584 * Several functions moved to lib/silcutil/silcutilc.[ch] from
585 old client implementation in silc/.
587 * Added support for callback functions in SILC_LOG_* macros.
588 Application can now set its own callbacks that will be called
589 instead of using the default functions that will always print
590 the debug messages to stderr (or stdout). Also, debugging can
591 now be disabled by setting silc_debug to FALSE and re-enabled by
592 setting it to TRUE. Note, that logging will still work even
593 if debugging is disabled.
595 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
596 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
597 silc_log_reset_debug_callbacks.
599 * To enable debugging in silc client one must give now -d
600 option on command line.
602 * Changed silc_schedule_init to automatically allocate task queues
603 if they are not allocated before calling it.
605 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Added GMP 3.1 into math library.
609 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
612 a channel in SILC network. The packet is used by servers and
613 routers to notify other routers that user has left a channel.
614 This little feature was missing until now. Added the feature
615 to protocol specification as well.
617 Added functions: silc_server_send_remove_channel_user and
618 silc_server_remove_channel_user into server.[ch].
620 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
621 lib/silccore/silcpacket.h. However, they are not implemented
624 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Fixed joining to a channel and sending channel messages
627 between server and router. The channel message sending should
628 now work inside a cell.
630 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
632 * Fixed the private message sending between server and router.
633 The private message sending should now work inside a cell.
635 * Added silc_server_replace_id into server.[ch] to replace
636 existing ID in the SILC network.
638 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
639 and silc_idlist_replace_server_id into idlist.[ch] in server.
641 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
643 * Fixed the server to server connections. Server can again now
644 connect to router. Router to router connections probably does
647 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Added dynamic protocol registering support. Now protocols can
650 registered and unregistered on the fly. Patch by cras.
652 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
654 * Added lib/contrib directory to hold routines that some platforms
655 don't have but are needed by SILC.
657 * Added getopt.c, getopt1.c and getopt.h from GNU C library
658 into lin/contrib to provide getopt() and getopt_long() for
659 those who don't have it.
661 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Added AWAY command to client. When away message is set and
664 client receives a private message packet the client automatically
665 replies to the sender with the away message.
667 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
668 bug seemed to be the cause of recent problems when compiling
671 * Added version detection support to SKE protocol specification
672 and added the new changes to the SKE implementation as well.
673 There were other minor changes in the SKE protocol as well.
675 Many changes in lib/silcske/silcske.[ch] and in
676 lib/silcske/payload.[ch].
678 * Added ^U functionality, clear input line. Patch from cras.
680 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * Mainly small bugfixes on core library. Fixed some debugging
683 logging and buffer overflow in silclog.c.
685 * Updated config.sub and config.guess on the distribution tree.
687 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
689 * Added command lagging support in server. Client may execute
690 commands now only once in two seconds.
692 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Optimized packet reception. MAC computation and checking is now
695 also more optimized. A lot previously duplicated code is now
696 used as generic by both client and server.
698 * Fixed key pair generation in clientutil.c
700 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Added into lib/silccore/silcbufutil.[ch] new function;
705 * Moved generic packet sending/encryption functions to
706 lib/silccore/silcpacket.[ch] from client and server. Some
707 rewriting of the functions.
709 * Moved all generic packet reception/decryption functions to
710 lib/silccore/silcpacket.[ch] from client and server. The
711 packet processing is now much cleaner in both client and server.
712 These were major changes in both client and server.
714 * Created many common functions in server to do packet sending.
715 Previously code were duplicated a lot, this has been removed
718 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Rewrote major parts of the ID cache system. Don't know
721 whether it is better now or not but at least the API is more
724 * Major rewrite on ID cache stuff on client because of the ID
725 cache API changes. Added idlist.c to client.
727 * Also major rewrite on ID cache stuff on server as well.
728 Major rewrite of idlist.[ch]. SilcXXXList's are now named
729 SilcXXXEntry's. We won't keep anymore idlist specific pointers
730 in hand, instead they are all put into the ID cache system now.
731 All server_idlist_* routines uses ID cache now instead of
732 traversing its own lists (those lists does not exist anymore).
733 SilcIDList though still exists. Also, SilcXXXEntry's are
736 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Finally made the SKE implementation compliant to the protocol
739 specification. All mp integers are now binary encoded as
740 opposed being HEX encoded.
742 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
745 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
746 functions: silc_[encode/decode]_pem. Also added function
747 silc_encode_pem_file to PEM encode with newlines ('\n') for
750 * SILC public keys are now encoded either PEM or binary. Same
751 option is for private keys as well. By default private keys
752 are binary encoded and public keys PEM encoded. Silly HEX
753 encoding were removed.
755 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
756 function to create fingerprints.
758 * Fixed a bug in SHA1; does not change the original data anymore.
760 * Partly implemented INFO command on client and server side.
761 Fixed CLEAR command. Changes to SERVER command; show current
762 server(s) when giving command without arguments. Added
763 VERSION command to client.
765 * Added check to server that unregistered connections cannot
766 execute commands (unless it is specificly allowed).
768 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Fixed screen refresh.
772 * Fixed channel joining bug from client. On some circumstances
773 client tried to join to a channel it had already joined.
775 * Added public key verification process into client's protocol.c.
776 The client now verifies the public key from user and saves
777 it into ~./silc/serverkeys/ directory.
779 Added into: clientutil.[ch]: silc_client_verify_server_key.
781 * Changed SKE protocol's silc_ske_initiator_finish function
782 to accept callback function that verifies the received public
783 key. Removed old silc_ske_verify_public_key function.
785 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
787 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
788 silc_pkcs_private_key[_data]_set.
790 * Made the password and public authentication more cleaner in
793 * Removed historic and obsolete protocol `channel_auth' from
794 both client and server.
796 * Removed wrong way of sending command status messages from
797 server to client in server's command.c. The old way violated
798 protocol specification.
800 Changes to silccore/silccommand.[ch]: removed
801 silc_command_encode_status_payload -> not needed anymore,
802 changed silc_command_encode_payload_va to accept extra
803 argument on variable argument list. The argument type must
804 now be provided to the function. Also, added new function:
805 silc_command_encode_reply_payload_va which is same as
806 normal command_encode_payload_va except command status type
807 is provided as extra argument.
809 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Added ~./silc directory handling. The directory includes the
812 public and private keys for the client.
814 Added silc_client_check_silc_dir, silc_client_create_identifier
815 and silc_client_load_keys.
817 * Implemented SILC protocol compliant public key. Added public
818 and private key saving to and loading from files.
820 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
821 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
822 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
823 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
824 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
826 Implemented: silc_pkcs_save_[public/private]_key[_data] and
827 silc_pkcs_load_[public/private]_key.
829 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Added silc_server_get_route (route.[ch]) to get connection
832 data for the fastest route for given ID.
834 * Implemented INVITE command on client and server. The command
835 were re-defined in the SILC Protocol Specification and the
836 implementation now complies with the specification.
838 * Implemented PING command on client and server.
840 * Implemented NAMES command on client and server. The server side
841 supports currently only normal server not router server yet.
842 Some changes to NAMES definition in SILC protocol specification.
844 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Implemented LEAVE command on client and server.
848 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
849 again. This change was made to the protocol as well. Server
850 should not violate the protocol specification anymore.
852 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
855 was tested. SOCKS4 was not but should work anyway.
