1 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Add route cache for received ID for fast routing.
5 * Added silc_server_packet_route to route received packet on router
6 that is not destined to us.
8 * Renamed silc_server_get_route to silc_server_route_get.
10 * Added id_string and id_string_len fields into SilcServer to
11 include encoded ServerID for fast comparing without excess
14 * Cleaned up WHOIS command on server side. Added following static
17 silc_server_command_whois_parse
18 silc_server_command_whois_check
19 silc_server_command_whois_send_reply
20 silc_server_command_whois_from_client
21 silc_server_command_whois_from_server
23 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
24 arguments in command replies. All command functions should be
25 updated to use this macro.
27 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
29 * Minor typo fixes on command reply handling on server.
31 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
33 * Added silc_server_command_add_to_channel internal routine to add
34 the client to the channel after router has created the channel and
35 sent command reply to the server.
37 * Added generic silc_server_send_command to send any command from
40 * Use static buffer with ID rendering instead of duplicating data.
42 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Fixed a channel user mode bug when joining to a channel server gave
45 everybody channel founder rights, oops.
47 * We mark ourselves as the router of the incoming server connection
48 if we are router ourselves. This way we can check in some packet
49 sending functions whether it is locally connected server. For
50 incoming router connections we put NULL.
52 * For router sending packets locally means now always sending the
53 packet cell wide; to local clients and local servers. For normal
54 server sending packet locally means sending it to only local
57 * Fixed the JOIN command to really work in router environment. If the
58 channel is created it is always created by the router. Router is
59 also responsible of making the initial joining to the channel,
60 sending JOIN notify to the sending server and distributing
61 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
62 does not exist server doesn't do anything else but forward the
63 command to the router which performs everything.
65 * Added silc_server_send_channel_key function to send the Channel Key
68 * Added silc_server_create_channel_key to create new channel key. The
69 channel key is now re-generated everytime someone joins or leaves
70 a channel, as protocol dictates. Note: channel->key_len is the
73 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
75 * Splitted server.[ch] finally. Created now packet_send.[ch] and
76 packet_receive.[ch] to separate packet sending and receiving
77 routines. The server.[ch] now includes everything else including
78 actual packet processing (writing and reading data) and other
81 Renamed silc_server_private_message_send_internal to
82 silc_server_send_private_message. The routine is still though
83 used only to relay private messages as server does not send
84 private messages itself.
86 Renamed silc_server_new_channel to silc_server_create_new_channel
87 and added new function sicl_server_new_channel that handles the
88 incoming New Channel packet. Added also new sending function
89 silc_server_send_new_channel to send New Channel Payload.
91 * Added new function silc_server_notify to process incoming notify
92 packet to the server/router. Server may then relay the notify
95 * Added new function silc_server_new_channel_user to process incoming
96 New Channel User packet. Router will redistribute the packet and
97 send JOIN notify to its local clients and locally connected servers
98 if needed. Normal server will send JOIN notify to its local client
99 on same channel when received this packet. Added also corresponding
100 sending function silc_server_send_new_channel_user to sent the
103 * Added boolean route argument to send_notif_to_channel and
104 packet_send_to_channel functions to attempt to route the packet
105 if it is TRUE and send only locally if it is FALSE.
107 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
109 * silc_server_replace_id now broadcasts the received replace ID
110 packet if it is not broadcast packet already. The router must
111 broadcast to inform other routers about changed ID.
113 * Added backpointer to server's router into SilcServer context in
114 silcd/server_internal.h.
116 * Fixed silc_server_packet_broadcast to send correct broadcast
119 * The channel key is now distributed to the local client as soon
120 as it is received from the router (in router environment) so that
121 no other packet may be sent for the channel until client has
124 * silc_server_remove_channel_user now broadcasts the received
125 Remove Channel User packet if it is not broadcast packet already.
126 The router must broadcast to inform other routers about removed
129 * Added users field into SilcPacketContext that is a reference count
130 of the context. One can increase the reference count by calling
131 silc_packet_context_dup which is now changed to just increase the
132 reference count instead of duplicating the data. The reference
133 count is decresed by calling silc_packet_context_free that will
134 free the data after the reference count hits zero.
136 For now on the packet context and everything allocated into it
137 (including the raw packet from network) must be freed by calling
138 the new silc_packet_context_free function. Added also new function
139 silc_packet_context_alloc that must be used now to allocate the
140 context. This also means that if a routine is asynchronous from
141 silc_[client/server]_packet_parse_type the packet context must
142 be duplicated by calling silc_packet_context_dup. Otherwise it
143 gets free'd after silc_[client/server]_packet_parse_type returns.
144 Also, one must remember that if packet is duplicated then its
145 reference count must be decresed by calling the free function as
146 many times as it was duplicated.
148 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
149 from both client and server.
151 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Made joining to a channel working in router environment.
155 * Cleaned up JOIN command on server side and create function
156 silc_server_command_join_channel internal routine to make the
159 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Changed silc_command_pending list to SilcDList. Also, added
162 `ident' field to SilcServerCommandPending structure to identify
163 the reply and to call correct callback.
165 Added silc_server_command_pending_check function to replace the
166 corresnponding macro. The silc_command_pending list is not
169 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
170 to set identifier to previously allocated Command Payload. It
171 is used to set identifier for command when resending Command
174 * Added silc_command_payload_encode_payload to encode Command
175 Payload buffer from SilcCommandPayload structure.
177 * Added silc_argument_payload_encode_payload to encode Argument
178 payload buffer from SilcArgumentPayload structure.
180 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
182 * Changed WHOIS command to support router connection on server side.
183 The whois request is always sent to router unless the server is
184 standalone server. After server has received the reply from the
185 router will it send the reply to the client.
187 * Added silc_server_packet_broadcast into silcd/server.[ch] to
188 broadcast received broadcast packet. The function is used only
189 by router. The broadcast packet is always sent to the router's
192 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
193 render given ID to printable string, for log files for example.
195 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
197 * Made basic router to router connections working. At least they
198 can now connect to each other but nothing really works the way
199 they are supposed - yet.
201 * Added new initiator token to RouterConnection configuration
202 file in silcd/serverconfig.[ch]. It is used to tell whether we
203 are the initiator to the remote router or whether we'll expect
204 the other end to connect.
206 * Moved registering of listener task to silc_server_init, hence
207 the server starts listenning as soon as it is run, even if it
208 does not have connections to other routers. Let's see how well
211 * Changed default connection retry timeouts for more suitable in
214 * Removed cipher and such arguments from silc_idlist_add_client
215 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
216 Added new function silc_idlist_add_data to add the keys and stuff
219 * Added SilcIDListData structure and added it to SilcClientEntry
220 and SilcServerEntry as their first field in the structure. This
221 way we can explicitly cast the ID entries to the SilcIDListData
222 structure and get common data for the entries. In past, we had
223 to first check what type of connection it is and then cast it to
224 correct ID entry type. Now, we can directly cast the opaque
225 pointer to the SilcIDListData (no matter what ID entry it actually
226 is) and get the data needed.
228 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Wow, found a bug in scheduler. The scheduler uninitialized itself
231 in some circumstances even if threre were timeout tasks, though not
232 IO tasks, but tasks anyway. Now fixed.
234 * Defined SilcServerConnection structure to hold connection specific
235 stuff about directly connected servers and routers. The definition
236 is currently in silcd/server_internal.h. I thought about having
237 a bit more important role fro this struct but for now it is used
238 only when connecting to other server (or router actually).
240 * Added connecting retry support in server when connecting to
241 router(s). The retry feature implement exponential backoff
242 algorithm. Also, added SilcServerParams structure to hold default
243 parameters for server. For now, it include these retry settings
244 and are hard coded. After server is moded to be as Silc Server
245 Library this structure will be more important.
247 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Changed client librarys channel->clients table to SilcList and
250 changed code accordingly.
252 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
254 * Changed client's channel table to SilcList and changed code
255 accordingly. Also changed SilcChannelClientEntry to include back-
256 pointer to the channel so that client entry can use that structure
257 as list as well and we have fast cross-reference to the channel.
258 This change dramatically decreased the complexity of channel
259 handling with client entry and vice versa (removed one extra
260 loop when searching for channel entry from many functions).
262 * Changed server->sim from table to SilcDList and changed code
265 * NAMES command can now be used from user interface. It will show
266 the user list on the channel, neatly.
268 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
269 Code now saves realname of the user if it becomes available.
271 * Renamed configure.in to configure.in.pre and made ./prepare
272 script to automatically add correct version string to
273 configure.in which it creates from configure.in.pre.
275 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
277 * NAMES command reply now shows users mode with the nickname when
280 * Moved silc_client_ch[u]mode[_char] functions from
281 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
282 place sucks, they are utility functions and should be in some
285 * Fixed some unsigned int's to unsigned short's. Patch by cras.
287 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
290 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Added TRQ (efficient deque and list library) into lib/trq. This is
295 a very good list library that is currently used in the SILC. Defined
296 SilcList API over the library because I didn't like the API very
297 much. See lib/trq/silclist.h for the API and examples of how to
298 use the API. Fixed various places in the code to use the new
299 SilcList API. The SilcList is meant for lists that has a structure
300 already defined as a list. It is not suitable to add just some
301 context to the list (in TRQ, the context is the list actually).
303 So, I defined SilcDList that can be used for the purpose where
304 predefined list structure does not exit. This can be used as
305 such list. Now some context just can be added to the SilcDList.
306 Currently this list is not used in the SILC just yet, though there
307 are a lot places where this can replace dynamically allocated
308 tables and I will fix these places, later, to use SilcDList.
309 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
310 and use TRQ internally).
312 Also fixed some annoying warning messages that the original TRQ
313 code generated. Also minor changes to TRQ's Makefile.in.
315 * Added support for querying by Client ID to both WHOIS and
316 IDENTIFY commands into server, as required by the protocol.
318 * Removed method function pointers from SilcBuffer structure. They
319 weren't used to anything and just increased the context size for
320 no good reason. This change also made silc_buffer_alloc and
321 silc_buffer_free functions inline functions.
323 * Disabled command flooding detection support until it's fixed so
324 that it accepts commands in but does not execute them more than once
327 * Added silc_net_localhost(), to return local hostname, into
328 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
329 that must be initialized before calling silc_client_init.
331 * Added new function: silc_server_send_notify_on_channels to send
332 notify messages to all channels client has joined. It is assured
333 that the message is sent only once per client.
335 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
336 lib/silcutil/silcutil.[ch] as silc_format function. The new
337 function is generic and is used by server as well, not only by
338 the logging routines.
340 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
341 the provided version string was not acceptable. Added new function:
342 silc_ske_check_version into lib/silcske/silcske.h. The function
343 must be implemented by the application (client or server) and it
344 does not reside in the SKE library. The function checks the version
345 string remote end sent.
347 * Added back pointers (to opaque context and to SilcSocketConnection)
348 into SilcPacketContext structure into lib/silccore/silcpacket.h.
350 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
351 duplicate packet context structure.
353 * Changed `notify' client operation to send same arguments as client
354 receives from server except for ID's. ID's are mapped to correct
355 ID entry and that is returned. Also, if channel entry is not sent
356 by server but the notify is for channel the channel entry is sent
357 to application (otherwise application doesn't know that it is for
358 channel (library gets it from packet's Destination ID)).
360 * Added silc_client_remove_from_channels into client library to
361 remove a client from all channels it has joined to. Used when
362 received SIGNOFF notify from server. Added also new function
363 silc_client_replace_from_channels to replace old ID entry with
364 new ID entry on all channels. Used when received NICK_CHANGE
367 * Fixed ID Cache list handling in silc_idlist_get_client in
368 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
369 to get (or query) client by ID.
373 * Added connection authentication status message defined by the
374 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
375 support for these into the code in client and server side.
377 * Added generic function silc_client_send_command to send any command
378 with variable argument list. Application should use this function
379 to send commands if the command functions provided by the library
380 does not suite for the application's user interface needs.
382 * Added new `failure' client operation. Application is notified about
383 received failure packet if client is executing a protocol. In this
384 case the protocol's execution has failed.
386 * Added SKE's end notify to send the SKE_SUCCESS notify message that
387 is required by the protocol.
389 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
390 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
393 * Added status flag to SilcSKE object to indicate realtime status
396 * Application receives now exactly same command reply arguments as
397 the library receives from server. However, if ID is received the
398 corresponding ID entry is returned to the application (eg. Client
399 ID is mapped to correct SilcClientEntry entry and that is returned).
400 Changed command_reply client operation due to this change.
402 * Changed all ID's in commands and in command replys as ID Payloads.
403 Change affected both client and server side codes.
405 All ID's sent in SILC network (with execption of ID's in SILC
406 Packet header) are sent in ID Payload to support variable length
409 * Server now notifies nick changes and notifies all clients on
410 the channels about the new nickname (about the new Client ID,
413 * Implemented CMODE command to change channel modes. Supports all
414 channel modes defined by the protocol specs except ban and invite
415 lists. (Also, private channel key mode is supported but support for
416 setting private channel key in client is missing, thus, this mode
417 has no effect on client side (except that server requires that the
418 client uses private channel key and normal channel traffic does not
421 Also, invite mode works per se, but INVITE command does not work
422 yet correctly, so you can set channel as invite only channel but
423 inviting clients to the channel does not work (it is yet to be
424 thought what's the best way to do it).
426 * Added new command SILC_COMMAND_CUMODE to change user mode on the
427 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
428 Implemented CUMODE command to change user's mode on the channel.
429 Supports all modes defined by the protocol specs.
431 * Added NAMES command reply to return users modes on the channel.
433 * Removed unnecessary and slow ciphers from lib/silccrypt.
435 * Set SO_KEEPALIVE option to connection sockets by default.
437 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
439 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
440 redefined the Notify Payload into protocol specs.
442 * Added silc_id_payload_parse_id to get ID directly from raw
445 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
448 accept searching by Client ID as well.
450 * Added support for LEAVE and SIGNOFF notify types in client library.
452 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
453 to parse ID Payload from raw data.
455 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
457 * Added flags parameter into silc_ske_assemble_security_properties
458 function in lib/silcske/silcske.[ch].
460 * Changed notify client operation to fit better for notify messages
461 sent by server. The notify payload received from server is now
462 passed to the application (after parsing it to SilcNotifyPayload).
463 It is application's responsibility to retrieve the arguments
464 from the payload and show the message the way it wants. The message
465 sent by server is implementation specific.
467 * Changed public keys to comply with the protocol specification.
468 Old public keys are not supported anymore and are not compatible.
470 * Removed nickname from Channel Payload as the latest draft removed
471 it. The client must resolve the nickname from the NAMES command
472 reply received when it joined the channel.
474 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
476 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * Fixed some errors in protocol specification drafts.
480 * Created lib/silccore/silcnotify.c to implement Notify Payload
481 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
482 generic payloads described by protocol specifications. The file
483 includes implementations for ID Payload and Argument Payload.
485 * Changed Command Payload implementation to use the new Argument
486 Payload. Changed command_xxxx_payload to command_payload_xxxx
487 to comply with SILC coding conventions.
489 * Added suppport for Argument Payload handling in Notify Payload
490 implementation as protocol requires it. Added the new support
491 into server and client lib as well.
493 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
495 * Added support for multiple nicknames on same channel. [n] is
496 added locally to the nickname if there are more than one same
497 nicknames on the channel.
499 * Server now sends all nicknames that matched WHOIS request.
500 Client also shows the list received from server.
502 * Added TOPIC command to client side. User can now set and show
503 current topic on channel.
505 * Added MOTD command to client and server. Also, server sends the
506 motd when client connects to the server.
508 * Changed version strings to comply ISO 8601.
510 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
512 * Fixed protocol error handling in client library. It should now
513 cope even if the SKE fails for some reason.
515 * Made new protocol specification drafts for submitting to IETF.
517 * Implemented TOPIC command to server in silcd/command.c.
519 * Added two new notify types into lib/silccore/silcnotify.h:
520 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
521 notify nickname change and topic setting/change on a channel.
523 * API change of command_reply operation in client library. The
524 application gets now the status type received from server as well.
526 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
528 * Removed the function just added to lib/silcutil/silcschedule.[ch].
530 * Cras fixed and optimized the packet handling even further and
531 it should work now. Minor change to the prototype of function
532 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
534 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Added new function into lib/silcutil/silcschedule.[ch]:
537 silc_schedule_with_fd to select() a specified fd. The function
538 returns after timeout expires or data arrives or goes. The
539 function is used by packet routines to wait that all data is
540 received from network.
542 * Fixed data reading from network in lib/silccore/silcpacket.c.
543 The code now assures that all data is read from the fd and then
544 continues packet processing. This was a bug fix since the code
545 used to drop some data in some circumstances.
547 * Added new function into lib/silcclient/client.[ch]:
548 silc_client_start_key_exchange to start key exchange after
549 connection has been established to server. The code internally
550 now uses this funtion but its main purpose was to provide it
551 for applications that perform their own connecting. After
552 application has created a connection it merely calls this
553 function to start the key exchange between client and server.
554 The library takes care of everything else after that.
556 Updated also lib/silcclient/README to explain the usage of
559 * Do not send to application information that connection has
560 been established. Application gets notified it by connect
563 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
565 * Applied cras's patch to add silc_schedule_one function. The
566 function runs scheduler once and returns.
568 * Fixed the scheduler after cras messed it up. The timeout
569 handling works now as it's supposed to work.
571 * Added into lib/silccore/ silcnotify.h to include notify
572 message types support. Changed silc_server_send_notify*
573 functions, in server.[ch], to support those new notify types.
574 Added the support for the notify types into client library,
575 as well. Added new notify client operation into ops.h in
578 * Changed silc_server_packet_send_to_channel to send normal
579 packets instead of just channel message packets. The function
580 is now used to send the notify packets to channels. It is not
581 used to send channel message packets anymore, as server never
584 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
585 va_arg()s as it seems to require it nowadays. I guess, if SILC
586 is compiled with older va_arg() the new code should work anyway.
588 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Splitted core library. Core library (lib/silccore) includes
591 now only SILC protocol specific core (and common) components.
592 Created new utility library (lib/silcutil) that includes more
593 generic purpose stuff. The stuff for util library was taken
594 from the old core library. This was minor and easy split.
596 * Created SILC Client Library (lib/silcclient) that includes
597 implementation of the SILC client without user interface. This
598 was major move from silc/ directory. The code has been changed
599 so that it is transparent towards the user interface. The
600 silc/ directory includes now the same user interface as before
601 and it uses the new client library. Read lib/silcclient/README.
602 Basicly, the client library performs everything else related
603 to SILC except user interface handling. Also, configuration
604 files are considered to be part of user interface and library
605 does not handle them.
607 This change also changed a lot of structures, function naming etc.
608 Most important change was that SilcClientWindow object was
609 renamed to SilcClientConnection in the client library. Created
610 also new file lib/silcclient/ops.h. Also added new files
611 silc/local_command.[ch] and silc/client_ops.[ch].
613 All these changes were made to make it easier for user interface
614 designers to create what ever user interface for the SILC client
617 It is also expected that the server will be moved to lib
618 directory as well and SILC Server Library will be created;
619 sometimes in the future.
621 * Removed Local commands from lib/silccore/silccommand.h as
622 they are application specific and new client library does not
623 handle any of those anymore.
625 * Several functions moved to lib/silcutil/silcutilc.[ch] from
626 old client implementation in silc/.
628 * Added support for callback functions in SILC_LOG_* macros.
629 Application can now set its own callbacks that will be called
630 instead of using the default functions that will always print
631 the debug messages to stderr (or stdout). Also, debugging can
632 now be disabled by setting silc_debug to FALSE and re-enabled by
633 setting it to TRUE. Note, that logging will still work even
634 if debugging is disabled.
636 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
637 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
638 silc_log_reset_debug_callbacks.
640 * To enable debugging in silc client one must give now -d
641 option on command line.
643 * Changed silc_schedule_init to automatically allocate task queues
644 if they are not allocated before calling it.
646 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * Added GMP 3.1 into math library.
650 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
652 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
653 a channel in SILC network. The packet is used by servers and
654 routers to notify other routers that user has left a channel.
655 This little feature was missing until now. Added the feature
656 to protocol specification as well.
658 Added functions: silc_server_send_remove_channel_user and
659 silc_server_remove_channel_user into server.[ch].
661 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
662 lib/silccore/silcpacket.h. However, they are not implemented
665 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
667 * Fixed joining to a channel and sending channel messages
668 between server and router. The channel message sending should
669 now work inside a cell.
671 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Fixed the private message sending between server and router.
674 The private message sending should now work inside a cell.
676 * Added silc_server_replace_id into server.[ch] to replace
677 existing ID in the SILC network.
679 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
680 and silc_idlist_replace_server_id into idlist.[ch] in server.
682 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Fixed the server to server connections. Server can again now
685 connect to router. Router to router connections probably does
688 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
690 * Added dynamic protocol registering support. Now protocols can
691 registered and unregistered on the fly. Patch by cras.
693 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
695 * Added lib/contrib directory to hold routines that some platforms
696 don't have but are needed by SILC.
698 * Added getopt.c, getopt1.c and getopt.h from GNU C library
699 into lin/contrib to provide getopt() and getopt_long() for
700 those who don't have it.
702 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Added AWAY command to client. When away message is set and
705 client receives a private message packet the client automatically
706 replies to the sender with the away message.
708 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
709 bug seemed to be the cause of recent problems when compiling
712 * Added version detection support to SKE protocol specification
713 and added the new changes to the SKE implementation as well.
714 There were other minor changes in the SKE protocol as well.
716 Many changes in lib/silcske/silcske.[ch] and in
717 lib/silcske/payload.[ch].
719 * Added ^U functionality, clear input line. Patch from cras.
721 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
723 * Mainly small bugfixes on core library. Fixed some debugging
724 logging and buffer overflow in silclog.c.
726 * Updated config.sub and config.guess on the distribution tree.
728 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Added command lagging support in server. Client may execute
731 commands now only once in two seconds.
733 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Optimized packet reception. MAC computation and checking is now
736 also more optimized. A lot previously duplicated code is now
737 used as generic by both client and server.
739 * Fixed key pair generation in clientutil.c
741 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
743 * Added into lib/silccore/silcbufutil.[ch] new function;
746 * Moved generic packet sending/encryption functions to
747 lib/silccore/silcpacket.[ch] from client and server. Some
748 rewriting of the functions.
750 * Moved all generic packet reception/decryption functions to
751 lib/silccore/silcpacket.[ch] from client and server. The
752 packet processing is now much cleaner in both client and server.
753 These were major changes in both client and server.
755 * Created many common functions in server to do packet sending.
756 Previously code were duplicated a lot, this has been removed
759 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
761 * Rewrote major parts of the ID cache system. Don't know
762 whether it is better now or not but at least the API is more
765 * Major rewrite on ID cache stuff on client because of the ID
766 cache API changes. Added idlist.c to client.
768 * Also major rewrite on ID cache stuff on server as well.
769 Major rewrite of idlist.[ch]. SilcXXXList's are now named
770 SilcXXXEntry's. We won't keep anymore idlist specific pointers
771 in hand, instead they are all put into the ID cache system now.
772 All server_idlist_* routines uses ID cache now instead of
773 traversing its own lists (those lists does not exist anymore).
774 SilcIDList though still exists. Also, SilcXXXEntry's are
777 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Finally made the SKE implementation compliant to the protocol
780 specification. All mp integers are now binary encoded as
781 opposed being HEX encoded.
783 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
786 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
787 functions: silc_[encode/decode]_pem. Also added function
788 silc_encode_pem_file to PEM encode with newlines ('\n') for
791 * SILC public keys are now encoded either PEM or binary. Same
792 option is for private keys as well. By default private keys
793 are binary encoded and public keys PEM encoded. Silly HEX
794 encoding were removed.
796 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
797 function to create fingerprints.
799 * Fixed a bug in SHA1; does not change the original data anymore.
801 * Partly implemented INFO command on client and server side.
802 Fixed CLEAR command. Changes to SERVER command; show current
803 server(s) when giving command without arguments. Added
804 VERSION command to client.
806 * Added check to server that unregistered connections cannot
807 execute commands (unless it is specificly allowed).
809 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Fixed screen refresh.
813 * Fixed channel joining bug from client. On some circumstances
814 client tried to join to a channel it had already joined.
816 * Added public key verification process into client's protocol.c.
817 The client now verifies the public key from user and saves
818 it into ~./silc/serverkeys/ directory.
820 Added into: clientutil.[ch]: silc_client_verify_server_key.
822 * Changed SKE protocol's silc_ske_initiator_finish function
823 to accept callback function that verifies the received public
824 key. Removed old silc_ske_verify_public_key function.
826 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
828 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
829 silc_pkcs_private_key[_data]_set.
831 * Made the password and public authentication more cleaner in
834 * Removed historic and obsolete protocol `channel_auth' from
835 both client and server.
837 * Removed wrong way of sending command status messages from
838 server to client in server's command.c. The old way violated
839 protocol specification.
841 Changes to silccore/silccommand.[ch]: removed
842 silc_command_encode_status_payload -> not needed anymore,
843 changed silc_command_encode_payload_va to accept extra
844 argument on variable argument list. The argument type must
845 now be provided to the function. Also, added new function:
846 silc_command_encode_reply_payload_va which is same as
847 normal command_encode_payload_va except command status type
848 is provided as extra argument.
850 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
852 * Added ~./silc directory handling. The directory includes the
853 public and private keys for the client.
855 Added silc_client_check_silc_dir, silc_client_create_identifier
856 and silc_client_load_keys.
858 * Implemented SILC protocol compliant public key. Added public
859 and private key saving to and loading from files.
861 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
862 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
863 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
864 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
865 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
867 Implemented: silc_pkcs_save_[public/private]_key[_data] and
868 silc_pkcs_load_[public/private]_key.
870 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
872 * Added silc_server_get_route (route.[ch]) to get connection
873 data for the fastest route for given ID.
875 * Implemented INVITE command on client and server. The command
876 were re-defined in the SILC Protocol Specification and the
877 implementation now complies with the specification.
879 * Implemented PING command on client and server.
881 * Implemented NAMES command on client and server. The server side
882 supports currently only normal server not router server yet.
883 Some changes to NAMES definition in SILC protocol specification.
885 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Implemented LEAVE command on client and server.
889 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
890 again. This change was made to the protocol as well. Server
891 should not violate the protocol specification anymore.
893 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
896 was tested. SOCKS4 was not but should work anyway.
