3 * A big code auditing weekend happening. Auditing code for
4 obvious mistakes, bugs and errors. Also, removing any code
7 Removed files for being obsolete:
9 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
10 inline in the file lib/silcutil/silcbuffer.h)
12 o lib/silcutil/silcbufutil.c (the header has inline versions)
14 Changed code to fix possible error conditions:
16 o The buffer formatting routines now check that the destination
17 buffer really has enough space to add the data. This applies for
18 both buffer formatting and unformatting
19 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
20 unformatting was changed to accomodate following rules:
21 XXX_*STRING_ALLOC will allocate space for the data into the pointer
22 sent to the function while XXX_*STRING will not allocate or copy
23 the data into the buffer. Instead it sets the pointer from the
24 buffer into the pointer sent as argument (XXX_*STRING used to
25 require that the pointer must be allocated already). This change
26 makes this whole thing a bit more consistent and more optimized
27 (note that the data returned in the unformatting with XXX_*STRING
28 must not be freed now). The routines return now -1 on error.
30 o Tried to find all code that use buffer_format and buffer_unformat
31 and added return value checking to prevent formatting and
32 especially unformatting errors and possible subsequent fatal
35 o Changed ske->x and ske->KEY to mallocated pointers in
36 lib/silcske/silcske.h. Fixed possible data and memory leak.
38 o Added return value checking to all *_parse* functions. Fixed
39 many memory leaks as well.
41 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
42 so that buffer overflows would not happen. All code now also
43 checks the return value as it can fail.
45 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
47 * Added reconnection support to server if the normal server looses
48 its connection to the router (for example if router is rebooted).
49 The server performs normal reconnection strategy implemented
50 to the server. Affected file silcd/server.c.
52 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Added new packet type SILC_PACKET_SET_MODE that is used to
55 distribute the information about changed modes (for clients,
56 channels and clients channel modes) to all routers in the
57 network. Updated the protocol specification accordingly.
59 Added functions into silcd/packet_send.c and
60 silcd/packet_receive.c: silc_server_send_set_mode,
63 Added new files silcmode.[ch] into lib/silccore that implements
64 the encoding and decoding of Set Mode Payload. Added new type
65 SilcSetModePayload. Moved the definitions of different modes
66 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
68 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Oops, a little mistake in server's connection authentication
71 protocol. The protocol is not ended with FAILURE but with
72 SUCCESS if the authentication is Ok. :) Affected file is
75 * Implemented NICK_CHANGE notify handling in server in the file
76 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
77 the local clients on the channel. After the changing nickname
78 in router environment snhould work and the [<unknown>] nickname
79 should appear no more.
81 The silc_server_replace_id function that receives the Replace ID
82 payload now sends the NICK_CHANGE notify type also in the file
83 silcd/packet_receive.c
85 * Changed WHOIS and IDENTIFY command to support the maximum amount
86 of arguments defined in protocol specs (3328 arguments). This
87 fixed a bug that caused problems when there were more than three
90 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
92 * Added extra parameter, command identifier, to the
93 silc_client_send_command so that explicit command identifier
96 Changed that ID list routines uses specific command identifier
97 when sending WHOIS/IDENTIFY requests to the server so that they
98 can be identified when the reply comes back.
100 Affected files lib/silcclient/command.[ch],
101 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
103 * Added `sender' argument to silc_server_packet_send_to_channel
104 to indicaet the sender who originally sent the packet to us
105 that we are now re-sending. Ignored if NULL. Affected file
106 silcd/packet_send.[ch].
108 * Added some server statistics support in silcd/server_internal.h
109 SilcServerStatistics structure and around the server code. Also
110 send some nice statistics information when client is connecting
113 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
115 * Fixed channel ID decoding in server's JOIN command reply in
116 silcd/command_reply.c
118 * Fixed braodcasting of replace ID payload to not to send it if
119 we are standalone server in silcd/packet_receive.c.
121 * Fixed all channel message sending routines to not to send
122 packets to clients that has router set, since they are routed
123 separately in the same function earlier. Affects file
124 silcd/packet_send.c and all channel packet sending functions.
126 * In USERS reply, res_argv[i] are not allocated, the table
127 is allocated. Thus changed that free the table, not its
130 * In server's whois_check and identify_check if the client is
131 locally connected do not send any WHOIS commands - they are not
134 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Fixed some minor bugs in client when sending WHOIS command. The
137 arguments was in wrong order.
139 * Removed statis function add_to_channel from server in
140 silcd/command.c that was previously used with the joining but
143 * Tested USERS command in router environment successfully with two
144 routers, two servers and two clients.
146 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Reorganized the USERS command and command reply in client library
149 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
150 When the command is given by user we register a pending command
151 callback that will reprocess the command after the reply has been
152 received from the server. When reprocessing the packet we then
153 display the information. Thus, the USERS information is displayed
154 now in the command callback instead of in the command reply
155 callback. The processing of the command is same as previously
156 when server has sent the command reply in the JOINing process.
158 * Added to USERS command in silcd/command_reply.c to join the client,
159 we didn't use to know about, to the channel after we've created
160 a client entry for it. Also, for clienet we did know already still
161 check whether it is on the channel or not and add it if not.
163 * Removed silc_server_command_join_notify as the function and its
166 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * Changed the client's pending command handling to the same as the
169 server's pending command handling. It is also now possible to
170 execute command reply functions from other command reply
171 function as the function callbacks for commands and command
172 replies are one and same. The pending commands are not static
173 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
174 in client connection context. Thus, pending commands are server
175 connection specific as it is convenient.
177 Changed the function silc_client_command_pending and
178 silc_client_command_pending_del and added new function
179 silc_client_command_pending_check. Removed the
180 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
183 * Added cmd_ident, current command identifier, to the client
184 connection context in lib/silcclient/client.h to keep track on
185 command identifiers used in command sending. Client's command reply
186 function handling now supports the mandatory command identifiers.
188 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
189 funtions in client to fully support pending command callbacks.
191 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
192 as one of the arguments to the application in the command reply
195 * NOTE: The FORWARDED flag is depracated. It used to be depracated
196 before first releasing SILC but came back. Now it is removed again
197 and should come back nomore. The FORWARDED flag was used only
198 by the JOINing procedure by forwarding the command packet to router.
199 Now, the JOINing procedure has been changed to more generic (due
200 to various router environment issues) and FORWARDED is not needed
201 anymore for anything. The protocol specification is yet to be
204 Now, removed silc_server_packet_forward from server and the flag
205 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
207 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Renamed NAMES command to USERS command. The NAMES was named that
210 due to historical reasons. Now it is renamed. Also, rewrote
211 parts of the USERS command. The nickname list is not sent anymore
212 by the server. Only Client ID and mode lists are sent in the USERS
213 command. Changed this also to the protocol specification.
215 The client now resolves the names and stuff after it receives
216 the USERS list from the server when joining to the channel.
218 * WHOIS and IDENTIFY commands has been changed to support multiple
219 Client ID's per command. One can now search for multiple users
220 in the network by sending only one WHOIS or IDENTIFY command.
221 Changed the code and the protocol specifications.
223 * Removed silc_server_command_identify_parse and changed that IDENTIFY
224 uses silc_server_command_whois_parse to parse the request. */
226 * If normal server, do not parse the WHOIS and IDENTIFY requests
227 before sending it to the router. Saves some time.
229 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Fixed JOIN command on client library. Wrong number of arguments
232 used to crash the client.
234 * Added silc_server_channel_has_global function to check whether
235 channel has global users or not.
237 * Added silc_server_channel_has_local function to check whether channel
238 has locally connected clients on the channel.
240 * The silc_server_remove_from_one_channel now checks whether the
241 channel has global users or not after given client was removed from
242 the channel. It also checks whether the channel has local clients
243 on the channel anymore. If it does not have then the channel entry
244 is removed as it is not needed anymore.
246 * The silc_server_notify now checks on JOIN notify whether the joining
247 client is one of locally connected or global. If it is global then
248 the channel has now global users on the channel and that is marked
249 to the channel entry. Also, it now saves the global client to
250 global list who is joining and JOINs it to the channel. This is
251 for normal server, that is.
253 Changed silc_server_send_notify_on_channel,
254 silc_server_packet_relay_to_channel and
255 silc_server_packet_send_to_channel check if we are normal server
256 and client has router set (ie. global client) do not send the
257 message to that client, as it is already routed to our router.
259 * Implemented LEAVE notify type handling in silc_server_notify
262 * Tested LEAVE command in router environment successfully. Tested
263 with two routers, two servers and two clients.
267 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
269 * Implemented SIGNOFF notify type handling in silc_server_notify
272 * silc_server_remove_id now removes the client entry from all channels
273 it has joined and thusly sends SIGNOFF notify type.
275 * Rewrote the NAMES list generation in server by removing two excess
276 loops. The lists are created now inside one loop.
278 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * silc_server_remove_channel_user checks now also global list
281 for channel and client.
283 * silc_server_new_channel_user checks now both local and global
284 list for channel and client. Fixed a bug in client id decoding.
285 Used to decode wrong buffer.
287 * silc_server_channel_message checks now both local and global
288 list for channel entry.
290 * Tested channel joining (hence JOIN) in router environment
291 successfully. Tested with two routers, two servers and two
294 * Tested channel message sending in router environment successfully.
296 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
298 * Added silc_server_save_channel_key into server.[ch] to save the
299 received channel key in Channel Key payload processing. It is
300 also used in JOIN command reply handling.
302 Equivalent function silc_client_save_channel_key added into
303 client.[ch] into client library.
305 * Changed JOIN command reply to send information whether the channel
306 was created or not (is existing already) and the channel key
307 payload. Changed protocol specs accordingly.
309 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
310 the request was sent by ID and not by nickname. Crashed on
313 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
315 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
316 now correctly save the received data.
318 * silc_server_free_sock_user_data now notifies routers in the
319 network about entities leaving the network.
321 At the same time implemented functions silc_server_remove_id
322 and silc_server_send_remove_id to receive and send REMOVE_ID
323 packets. The packet is used to notify routers in the network
324 about leaving entities. The ID removed will become invalid in
327 * Added function silc_idlist_del_server into server. Removes and
328 free's server entry from ID list.
330 * silc_server_private_message function now checks, if we are router,
331 that the destination ID really is valid ID, naturally.
333 * In router when NEW_ID packet is received (for new client) the
334 hash of the Client ID is saved in the ID Cache but the
335 client->nickname is set to NULL, instead of putting the hash
338 IDENTIFY command now also checks that client->nickname must be
339 valid. If it is not if will request the data from the server who
340 owns the client. Added new function
341 silc_server_command_identify_check.
343 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
344 to set the command to already allocated Command Payload.
346 * Tested private message sending in router environment with two
347 routers, two servers and two clients. Fixed minor bugs and now
350 * Fixed segfault from client's NAMES command. Used to crash if
353 * Forwarded packets must not be routed even if it is not destined
354 to the receiver. Changed server code comply with this.
356 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Added `require_reverse_mapping' boolean value to ServerParams
359 structure. If TRUE (not default) the server will require that
360 the connecting host has fully qualified domain name.
362 If the reverse mapping is not required and hostname could not be
363 found the IP address is used as hostname.
365 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Implemented version string checking to both client and server.
368 The check is incomplete currently due to the abnormal version
369 strings used in development version of SILC.
371 * Changed all command functions in server to use the new
374 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Changed char *data to unsigned char *data in ID Cache system to
377 support binary data as ID Cache data. Changed code to support
378 binary data in lib/silccore/idcache.c.
380 * Renamed silc_server_packet_relay_command_reply to
381 silc_server_command_reply as it is normal packet receiving
382 function. Rewrote the function to accept command replys for
383 servers and not only for clients.
385 * Mark remote router always as registered server if we are connecting
386 to it. Otherwise, commands sent by the router to us are ignored.
388 * All ID List find routines now returns the ID Cache Entry pointer
389 as well if requested.
391 * WHOIS command works now in router environment, tested with two
392 routers, two servers and two clients.
394 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
395 in router environment (as it is almost equivalent to WHOIS) but
396 hasn't been tested thoroughly. Added new functions:
398 silc_server_command_identify_parse
399 silc_server_command_identify_send_reply
400 silc_server_command_identify_from_client
401 silc_server_command_identify_from_server
403 * Disabled route cache adding because adding two different ID's with
404 same IP replaces the old cache entry thus giving wrong route.
405 The entry->router->connection is always the fastest route anyway
406 so route cache may not be needed. Of course, new routes maybe
407 established after receiving the ID when the entry->router->connection
408 might not be anymore the most optimal.
410 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Add route cache for received ID for fast routing.
414 * Added silc_server_packet_route to route received packet on router
415 that is not destined to us.
417 * Renamed silc_server_get_route to silc_server_route_get.
419 * Added id_string and id_string_len fields into SilcServer to
420 include encoded ServerID for fast comparing without excess
421 encoding of the ID's.
423 * Cleaned up WHOIS command on server side. Added following static
426 silc_server_command_whois_parse
427 silc_server_command_whois_check
428 silc_server_command_whois_send_reply
429 silc_server_command_whois_from_client
430 silc_server_command_whois_from_server
432 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
433 arguments in command replies. All command functions should be
434 updated to use this macro.
436 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * Minor typo fixes on command reply handling on server.
440 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Added silc_server_command_add_to_channel internal routine to add
443 the client to the channel after router has created the channel and
444 sent command reply to the server.
446 * Added generic silc_server_send_command to send any command from
449 * Use static buffer with ID rendering instead of duplicating data.
451 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Fixed a channel user mode bug when joining to a channel server gave
454 everybody channel founder rights, oops.
456 * We mark ourselves as the router of the incoming server connection
457 if we are router ourselves. This way we can check in some packet
458 sending functions whether it is locally connected server. For
459 incoming router connections we put NULL.
461 * For router sending packets locally means now always sending the
462 packet cell wide; to local clients and local servers. For normal
463 server sending packet locally means sending it to only local
466 * Fixed the JOIN command to really work in router environment. If the
467 channel is created it is always created by the router. Router is
468 also responsible of making the initial joining to the channel,
469 sending JOIN notify to the sending server and distributing
470 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
471 does not exist server doesn't do anything else but forward the
472 command to the router which performs everything.
474 * Added silc_server_send_channel_key function to send the Channel Key
477 * Added silc_server_create_channel_key to create new channel key. The
478 channel key is now re-generated everytime someone joins or leaves
479 a channel, as protocol dictates. Note: channel->key_len is the
482 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
484 * Splitted server.[ch] finally. Created now packet_send.[ch] and
485 packet_receive.[ch] to separate packet sending and receiving
486 routines. The server.[ch] now includes everything else including
487 actual packet processing (writing and reading data) and other
490 Renamed silc_server_private_message_send_internal to
491 silc_server_send_private_message. The routine is still though
492 used only to relay private messages as server does not send
493 private messages itself.
495 Renamed silc_server_new_channel to silc_server_create_new_channel
496 and added new function sicl_server_new_channel that handles the
497 incoming New Channel packet. Added also new sending function
498 silc_server_send_new_channel to send New Channel Payload.
500 * Added new function silc_server_notify to process incoming notify
501 packet to the server/router. Server may then relay the notify
502 to clients if needed.
504 * Added new function silc_server_new_channel_user to process incoming
505 New Channel User packet. Router will redistribute the packet and
506 send JOIN notify to its local clients and locally connected servers
507 if needed. Normal server will send JOIN notify to its local client
508 on same channel when received this packet. Added also corresponding
509 sending function silc_server_send_new_channel_user to sent the
512 * Added boolean route argument to send_notif_to_channel and
513 packet_send_to_channel functions to attempt to route the packet
514 if it is TRUE and send only locally if it is FALSE.
516 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
518 * silc_server_replace_id now broadcasts the received replace ID
519 packet if it is not broadcast packet already. The router must
520 broadcast to inform other routers about changed ID.
522 * Added backpointer to server's router into SilcServer context in
523 silcd/server_internal.h.
525 * Fixed silc_server_packet_broadcast to send correct broadcast
528 * The channel key is now distributed to the local client as soon
529 as it is received from the router (in router environment) so that
530 no other packet may be sent for the channel until client has
533 * silc_server_remove_channel_user now broadcasts the received
534 Remove Channel User packet if it is not broadcast packet already.
535 The router must broadcast to inform other routers about removed
538 * Added users field into SilcPacketContext that is a reference count
539 of the context. One can increase the reference count by calling
540 silc_packet_context_dup which is now changed to just increase the
541 reference count instead of duplicating the data. The reference
542 count is decresed by calling silc_packet_context_free that will
543 free the data after the reference count hits zero.
545 For now on the packet context and everything allocated into it
546 (including the raw packet from network) must be freed by calling
547 the new silc_packet_context_free function. Added also new function
548 silc_packet_context_alloc that must be used now to allocate the
549 context. This also means that if a routine is asynchronous from
550 silc_[client/server]_packet_parse_type the packet context must
551 be duplicated by calling silc_packet_context_dup. Otherwise it
552 gets free'd after silc_[client/server]_packet_parse_type returns.
553 Also, one must remember that if packet is duplicated then its
554 reference count must be decresed by calling the free function as
555 many times as it was duplicated.
557 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
558 from both client and server.
560 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Made joining to a channel working in router environment.
564 * Cleaned up JOIN command on server side and create function
565 silc_server_command_join_channel internal routine to make the
568 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Changed silc_command_pending list to SilcDList. Also, added
571 `ident' field to SilcServerCommandPending structure to identify
572 the reply and to call correct callback.
574 Added silc_server_command_pending_check function to replace the
575 corresnponding macro. The silc_command_pending list is not
578 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
579 to set identifier to previously allocated Command Payload. It
580 is used to set identifier for command when resending Command
583 * Added silc_command_payload_encode_payload to encode Command
584 Payload buffer from SilcCommandPayload structure.
586 * Added silc_argument_payload_encode_payload to encode Argument
587 payload buffer from SilcArgumentPayload structure.
589 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
591 * Changed WHOIS command to support router connection on server side.
592 The whois request is always sent to router unless the server is
593 standalone server. After server has received the reply from the
594 router will it send the reply to the client.
596 * Added silc_server_packet_broadcast into silcd/server.[ch] to
597 broadcast received broadcast packet. The function is used only
598 by router. The broadcast packet is always sent to the router's
601 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
602 render given ID to printable string, for log files for example.
604 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Made basic router to router connections working. At least they
607 can now connect to each other but nothing really works the way
608 they are supposed - yet.
610 * Added new initiator token to RouterConnection configuration
611 file in silcd/serverconfig.[ch]. It is used to tell whether we
612 are the initiator to the remote router or whether we'll expect
613 the other end to connect.
615 * Moved registering of listener task to silc_server_init, hence
616 the server starts listenning as soon as it is run, even if it
617 does not have connections to other routers. Let's see how well
620 * Changed default connection retry timeouts for more suitable in
623 * Removed cipher and such arguments from silc_idlist_add_client
624 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
625 Added new function silc_idlist_add_data to add the keys and stuff
628 * Added SilcIDListData structure and added it to SilcClientEntry
629 and SilcServerEntry as their first field in the structure. This
630 way we can explicitly cast the ID entries to the SilcIDListData
631 structure and get common data for the entries. In past, we had
632 to first check what type of connection it is and then cast it to
633 correct ID entry type. Now, we can directly cast the opaque
634 pointer to the SilcIDListData (no matter what ID entry it actually
635 is) and get the data needed.
637 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
639 * Wow, found a bug in scheduler. The scheduler uninitialized itself
640 in some circumstances even if threre were timeout tasks, though not
641 IO tasks, but tasks anyway. Now fixed.
643 * Defined SilcServerConnection structure to hold connection specific
644 stuff about directly connected servers and routers. The definition
645 is currently in silcd/server_internal.h. I thought about having
646 a bit more important role fro this struct but for now it is used
647 only when connecting to other server (or router actually).
649 * Added connecting retry support in server when connecting to
650 router(s). The retry feature implement exponential backoff
651 algorithm. Also, added SilcServerParams structure to hold default
652 parameters for server. For now, it include these retry settings
653 and are hard coded. After server is moded to be as Silc Server
654 Library this structure will be more important.
656 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
658 * Changed client librarys channel->clients table to SilcList and
659 changed code accordingly.
661 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Changed client's channel table to SilcList and changed code
664 accordingly. Also changed SilcChannelClientEntry to include back-
665 pointer to the channel so that client entry can use that structure
666 as list as well and we have fast cross-reference to the channel.
667 This change dramatically decreased the complexity of channel
668 handling with client entry and vice versa (removed one extra
669 loop when searching for channel entry from many functions).
671 * Changed server->sim from table to SilcDList and changed code
674 * NAMES command can now be used from user interface. It will show
675 the user list on the channel, neatly.
677 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
678 Code now saves realname of the user if it becomes available.
680 * Renamed configure.in to configure.in.pre and made ./prepare
681 script to automatically add correct version string to
682 configure.in which it creates from configure.in.pre.
684 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * NAMES command reply now shows users mode with the nickname when
689 * Moved silc_client_ch[u]mode[_char] functions from
690 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
691 place sucks, they are utility functions and should be in some
694 * Fixed some unsigned int's to unsigned short's. Patch by cras.
696 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
699 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Added TRQ (efficient deque and list library) into lib/trq. This is
704 a very good list library that is currently used in the SILC. Defined
705 SilcList API over the library because I didn't like the API very
706 much. See lib/trq/silclist.h for the API and examples of how to
707 use the API. Fixed various places in the code to use the new
708 SilcList API. The SilcList is meant for lists that has a structure
709 already defined as a list. It is not suitable to add just some
710 context to the list (in TRQ, the context is the list actually).
712 So, I defined SilcDList that can be used for the purpose where
713 predefined list structure does not exit. This can be used as
714 such list. Now some context just can be added to the SilcDList.
715 Currently this list is not used in the SILC just yet, though there
716 are a lot places where this can replace dynamically allocated
717 tables and I will fix these places, later, to use SilcDList.
718 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
719 and use TRQ internally).
721 Also fixed some annoying warning messages that the original TRQ
722 code generated. Also minor changes to TRQ's Makefile.in.
724 * Added support for querying by Client ID to both WHOIS and
725 IDENTIFY commands into server, as required by the protocol.
727 * Removed method function pointers from SilcBuffer structure. They
728 weren't used to anything and just increased the context size for
729 no good reason. This change also made silc_buffer_alloc and
730 silc_buffer_free functions inline functions.
732 * Disabled command flooding detection support until it's fixed so
733 that it accepts commands in but does not execute them more than once
736 * Added silc_net_localhost(), to return local hostname, into
737 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
738 that must be initialized before calling silc_client_init.
740 * Added new function: silc_server_send_notify_on_channels to send
741 notify messages to all channels client has joined. It is assured
742 that the message is sent only once per client.
744 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
745 lib/silcutil/silcutil.[ch] as silc_format function. The new
746 function is generic and is used by server as well, not only by
747 the logging routines.
749 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
750 the provided version string was not acceptable. Added new function:
751 silc_ske_check_version into lib/silcske/silcske.h. The function
752 must be implemented by the application (client or server) and it
753 does not reside in the SKE library. The function checks the version
754 string remote end sent.
756 * Added back pointers (to opaque context and to SilcSocketConnection)
757 into SilcPacketContext structure into lib/silccore/silcpacket.h.
759 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
760 duplicate packet context structure.
762 * Changed `notify' client operation to send same arguments as client
763 receives from server except for ID's. ID's are mapped to correct
764 ID entry and that is returned. Also, if channel entry is not sent
765 by server but the notify is for channel the channel entry is sent
766 to application (otherwise application doesn't know that it is for
767 channel (library gets it from packet's Destination ID)).
769 * Added silc_client_remove_from_channels into client library to
770 remove a client from all channels it has joined to. Used when
771 received SIGNOFF notify from server. Added also new function
772 silc_client_replace_from_channels to replace old ID entry with
773 new ID entry on all channels. Used when received NICK_CHANGE
776 * Fixed ID Cache list handling in silc_idlist_get_client in
777 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
778 to get (or query) client by ID.
782 * Added connection authentication status message defined by the
783 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
784 support for these into the code in client and server side.
786 * Added generic function silc_client_send_command to send any command
787 with variable argument list. Application should use this function
788 to send commands if the command functions provided by the library
789 does not suite for the application's user interface needs.
791 * Added new `failure' client operation. Application is notified about
792 received failure packet if client is executing a protocol. In this
793 case the protocol's execution has failed.
795 * Added SKE's end notify to send the SKE_SUCCESS notify message that
796 is required by the protocol.
798 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
799 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
802 * Added status flag to SilcSKE object to indicate realtime status
805 * Application receives now exactly same command reply arguments as
806 the library receives from server. However, if ID is received the
807 corresponding ID entry is returned to the application (eg. Client
808 ID is mapped to correct SilcClientEntry entry and that is returned).
809 Changed command_reply client operation due to this change.
811 * Changed all ID's in commands and in command replys as ID Payloads.
812 Change affected both client and server side codes.
814 All ID's sent in SILC network (with execption of ID's in SILC
815 Packet header) are sent in ID Payload to support variable length
818 * Server now notifies nick changes and notifies all clients on
819 the channels about the new nickname (about the new Client ID,
822 * Implemented CMODE command to change channel modes. Supports all
823 channel modes defined by the protocol specs except ban and invite
824 lists. (Also, private channel key mode is supported but support for
825 setting private channel key in client is missing, thus, this mode
826 has no effect on client side (except that server requires that the
827 client uses private channel key and normal channel traffic does not
830 Also, invite mode works per se, but INVITE command does not work
831 yet correctly, so you can set channel as invite only channel but
832 inviting clients to the channel does not work (it is yet to be
833 thought what's the best way to do it).
835 * Added new command SILC_COMMAND_CUMODE to change user mode on the
836 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
837 Implemented CUMODE command to change user's mode on the channel.
838 Supports all modes defined by the protocol specs.
840 * Added NAMES command reply to return users modes on the channel.
842 * Removed unnecessary and slow ciphers from lib/silccrypt.
844 * Set SO_KEEPALIVE option to connection sockets by default.
846 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
848 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
849 redefined the Notify Payload into protocol specs.
851 * Added silc_id_payload_parse_id to get ID directly from raw
854 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
857 accept searching by Client ID as well.
859 * Added support for LEAVE and SIGNOFF notify types in client library.
861 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
862 to parse ID Payload from raw data.
864 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Added flags parameter into silc_ske_assemble_security_properties
867 function in lib/silcske/silcske.[ch].
869 * Changed notify client operation to fit better for notify messages
870 sent by server. The notify payload received from server is now
871 passed to the application (after parsing it to SilcNotifyPayload).
872 It is application's responsibility to retrieve the arguments
873 from the payload and show the message the way it wants. The message
874 sent by server is implementation specific.
876 * Changed public keys to comply with the protocol specification.
877 Old public keys are not supported anymore and are not compatible.
879 * Removed nickname from Channel Payload as the latest draft removed
880 it. The client must resolve the nickname from the NAMES command
881 reply received when it joined the channel.
883 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
885 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
887 * Fixed some errors in protocol specification drafts.
889 * Created lib/silccore/silcnotify.c to implement Notify Payload
890 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
891 generic payloads described by protocol specifications. The file
892 includes implementations for ID Payload and Argument Payload.
894 * Changed Command Payload implementation to use the new Argument
895 Payload. Changed command_xxxx_payload to command_payload_xxxx
896 to comply with SILC coding conventions.
898 * Added suppport for Argument Payload handling in Notify Payload
899 implementation as protocol requires it. Added the new support
900 into server and client lib as well.
902 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
904 * Added support for multiple nicknames on same channel. [n] is
905 added locally to the nickname if there are more than one same
906 nicknames on the channel.
908 * Server now sends all nicknames that matched WHOIS request.
909 Client also shows the list received from server.
911 * Added TOPIC command to client side. User can now set and show
912 current topic on channel.
914 * Added MOTD command to client and server. Also, server sends the
915 motd when client connects to the server.
917 * Changed version strings to comply ISO 8601.
919 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Fixed protocol error handling in client library. It should now
922 cope even if the SKE fails for some reason.
924 * Made new protocol specification drafts for submitting to IETF.
926 * Implemented TOPIC command to server in silcd/command.c.
928 * Added two new notify types into lib/silccore/silcnotify.h:
929 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
930 notify nickname change and topic setting/change on a channel.
932 * API change of command_reply operation in client library. The
933 application gets now the status type received from server as well.
935 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Removed the function just added to lib/silcutil/silcschedule.[ch].
939 * Cras fixed and optimized the packet handling even further and
940 it should work now. Minor change to the prototype of function
941 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
943 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Added new function into lib/silcutil/silcschedule.[ch]:
946 silc_schedule_with_fd to select() a specified fd. The function
947 returns after timeout expires or data arrives or goes. The
948 function is used by packet routines to wait that all data is
949 received from network.
951 * Fixed data reading from network in lib/silccore/silcpacket.c.
952 The code now assures that all data is read from the fd and then
953 continues packet processing. This was a bug fix since the code
954 used to drop some data in some circumstances.
956 * Added new function into lib/silcclient/client.[ch]:
957 silc_client_start_key_exchange to start key exchange after
958 connection has been established to server. The code internally
959 now uses this funtion but its main purpose was to provide it
960 for applications that perform their own connecting. After
961 application has created a connection it merely calls this
962 function to start the key exchange between client and server.
963 The library takes care of everything else after that.
965 Updated also lib/silcclient/README to explain the usage of
968 * Do not send to application information that connection has
969 been established. Application gets notified it by connect
972 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Applied cras's patch to add silc_schedule_one function. The
975 function runs scheduler once and returns.
977 * Fixed the scheduler after cras messed it up. The timeout
978 handling works now as it's supposed to work.
980 * Added into lib/silccore/ silcnotify.h to include notify
981 message types support. Changed silc_server_send_notify*
982 functions, in server.[ch], to support those new notify types.
983 Added the support for the notify types into client library,
984 as well. Added new notify client operation into ops.h in
987 * Changed silc_server_packet_send_to_channel to send normal
988 packets instead of just channel message packets. The function
989 is now used to send the notify packets to channels. It is not
990 used to send channel message packets anymore, as server never
993 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
994 va_arg()s as it seems to require it nowadays. I guess, if SILC
995 is compiled with older va_arg() the new code should work anyway.
997 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
999 * Splitted core library. Core library (lib/silccore) includes
1000 now only SILC protocol specific core (and common) components.
1001 Created new utility library (lib/silcutil) that includes more
1002 generic purpose stuff. The stuff for util library was taken
1003 from the old core library. This was minor and easy split.
1005 * Created SILC Client Library (lib/silcclient) that includes
1006 implementation of the SILC client without user interface. This
1007 was major move from silc/ directory. The code has been changed
1008 so that it is transparent towards the user interface. The
1009 silc/ directory includes now the same user interface as before
1010 and it uses the new client library. Read lib/silcclient/README.
1011 Basicly, the client library performs everything else related
1012 to SILC except user interface handling. Also, configuration
1013 files are considered to be part of user interface and library
1014 does not handle them.
1016 This change also changed a lot of structures, function naming etc.
1017 Most important change was that SilcClientWindow object was
1018 renamed to SilcClientConnection in the client library. Created
1019 also new file lib/silcclient/ops.h. Also added new files
1020 silc/local_command.[ch] and silc/client_ops.[ch].
1022 All these changes were made to make it easier for user interface
1023 designers to create what ever user interface for the SILC client
1026 It is also expected that the server will be moved to lib
1027 directory as well and SILC Server Library will be created;
1028 sometimes in the future.
1030 * Removed Local commands from lib/silccore/silccommand.h as
1031 they are application specific and new client library does not
1032 handle any of those anymore.
1034 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1035 old client implementation in silc/.
1037 * Added support for callback functions in SILC_LOG_* macros.
1038 Application can now set its own callbacks that will be called
1039 instead of using the default functions that will always print
1040 the debug messages to stderr (or stdout). Also, debugging can
1041 now be disabled by setting silc_debug to FALSE and re-enabled by
1042 setting it to TRUE. Note, that logging will still work even
1043 if debugging is disabled.
1045 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1046 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1047 silc_log_reset_debug_callbacks.
1049 * To enable debugging in silc client one must give now -d
1050 option on command line.
1052 * Changed silc_schedule_init to automatically allocate task queues
1053 if they are not allocated before calling it.
1055 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Added GMP 3.1 into math library.
1059 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1061 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1062 a channel in SILC network. The packet is used by servers and
1063 routers to notify other routers that user has left a channel.
1064 This little feature was missing until now. Added the feature
1065 to protocol specification as well.
1067 Added functions: silc_server_send_remove_channel_user and
1068 silc_server_remove_channel_user into server.[ch].
1070 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1071 lib/silccore/silcpacket.h. However, they are not implemented
1074 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1076 * Fixed joining to a channel and sending channel messages
1077 between server and router. The channel message sending should
1078 now work inside a cell.
1080 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1082 * Fixed the private message sending between server and router.
1083 The private message sending should now work inside a cell.
1085 * Added silc_server_replace_id into server.[ch] to replace
1086 existing ID in the SILC network.
1088 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1089 and silc_idlist_replace_server_id into idlist.[ch] in server.
1091 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1093 * Fixed the server to server connections. Server can again now
1094 connect to router. Router to router connections probably does
1097 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1099 * Added dynamic protocol registering support. Now protocols can
1100 registered and unregistered on the fly. Patch by cras.
1102 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added lib/contrib directory to hold routines that some platforms
1105 don't have but are needed by SILC.
1107 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1108 into lin/contrib to provide getopt() and getopt_long() for
1109 those who don't have it.
1111 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Added AWAY command to client. When away message is set and
1114 client receives a private message packet the client automatically
1115 replies to the sender with the away message.
1117 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1118 bug seemed to be the cause of recent problems when compiling
1121 * Added version detection support to SKE protocol specification
1122 and added the new changes to the SKE implementation as well.
1123 There were other minor changes in the SKE protocol as well.
1125 Many changes in lib/silcske/silcske.[ch] and in
1126 lib/silcske/payload.[ch].
1128 * Added ^U functionality, clear input line. Patch from cras.
1130 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1132 * Mainly small bugfixes on core library. Fixed some debugging
1133 logging and buffer overflow in silclog.c.
1135 * Updated config.sub and config.guess on the distribution tree.
1137 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * Added command lagging support in server. Client may execute
1140 commands now only once in two seconds.
1142 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Optimized packet reception. MAC computation and checking is now
1145 also more optimized. A lot previously duplicated code is now
1146 used as generic by both client and server.
1148 * Fixed key pair generation in clientutil.c
1150 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1152 * Added into lib/silccore/silcbufutil.[ch] new function;
1153 silc_buffer_realloc.
1155 * Moved generic packet sending/encryption functions to
1156 lib/silccore/silcpacket.[ch] from client and server. Some
1157 rewriting of the functions.
1159 * Moved all generic packet reception/decryption functions to
1160 lib/silccore/silcpacket.[ch] from client and server. The
1161 packet processing is now much cleaner in both client and server.
1162 These were major changes in both client and server.
1164 * Created many common functions in server to do packet sending.
1165 Previously code were duplicated a lot, this has been removed
1168 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Rewrote major parts of the ID cache system. Don't know
1171 whether it is better now or not but at least the API is more
1174 * Major rewrite on ID cache stuff on client because of the ID
1175 cache API changes. Added idlist.c to client.
1177 * Also major rewrite on ID cache stuff on server as well.
1178 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1179 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1180 in hand, instead they are all put into the ID cache system now.
1181 All server_idlist_* routines uses ID cache now instead of
1182 traversing its own lists (those lists does not exist anymore).
1183 SilcIDList though still exists. Also, SilcXXXEntry's are
1186 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Finally made the SKE implementation compliant to the protocol
1189 specification. All mp integers are now binary encoded as
1190 opposed being HEX encoded.
1192 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1195 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1196 functions: silc_[encode/decode]_pem. Also added function
1197 silc_encode_pem_file to PEM encode with newlines ('\n') for
1200 * SILC public keys are now encoded either PEM or binary. Same
1201 option is for private keys as well. By default private keys
1202 are binary encoded and public keys PEM encoded. Silly HEX
1203 encoding were removed.
1205 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1206 function to create fingerprints.
1208 * Fixed a bug in SHA1; does not change the original data anymore.
1210 * Partly implemented INFO command on client and server side.
1211 Fixed CLEAR command. Changes to SERVER command; show current
1212 server(s) when giving command without arguments. Added
1213 VERSION command to client.
1215 * Added check to server that unregistered connections cannot
1216 execute commands (unless it is specificly allowed).
1218 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1220 * Fixed screen refresh.
1222 * Fixed channel joining bug from client. On some circumstances
1223 client tried to join to a channel it had already joined.
1225 * Added public key verification process into client's protocol.c.
1226 The client now verifies the public key from user and saves
1227 it into ~./silc/serverkeys/ directory.
1229 Added into: clientutil.[ch]: silc_client_verify_server_key.
1231 * Changed SKE protocol's silc_ske_initiator_finish function
1232 to accept callback function that verifies the received public
1233 key. Removed old silc_ske_verify_public_key function.
1235 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1238 silc_pkcs_private_key[_data]_set.
1240 * Made the password and public authentication more cleaner in
1241 server's protocol.c.
1243 * Removed historic and obsolete protocol `channel_auth' from
1244 both client and server.
1246 * Removed wrong way of sending command status messages from
1247 server to client in server's command.c. The old way violated
1248 protocol specification.
1250 Changes to silccore/silccommand.[ch]: removed
1251 silc_command_encode_status_payload -> not needed anymore,
1252 changed silc_command_encode_payload_va to accept extra
1253 argument on variable argument list. The argument type must
1254 now be provided to the function. Also, added new function:
1255 silc_command_encode_reply_payload_va which is same as
1256 normal command_encode_payload_va except command status type
1257 is provided as extra argument.
1259 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1261 * Added ~./silc directory handling. The directory includes the
1262 public and private keys for the client.
1264 Added silc_client_check_silc_dir, silc_client_create_identifier
1265 and silc_client_load_keys.
1267 * Implemented SILC protocol compliant public key. Added public
1268 and private key saving to and loading from files.
1270 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1271 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1272 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1273 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1274 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1276 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1277 silc_pkcs_load_[public/private]_key.
1279 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Added silc_server_get_route (route.[ch]) to get connection
1282 data for the fastest route for given ID.
1284 * Implemented INVITE command on client and server. The command
1285 were re-defined in the SILC Protocol Specification and the
1286 implementation now complies with the specification.
1288 * Implemented PING command on client and server.
1290 * Implemented NAMES command on client and server. The server side
1291 supports currently only normal server not router server yet.
1292 Some changes to NAMES definition in SILC protocol specification.
1294 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1296 * Implemented LEAVE command on client and server.
1298 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1299 again. This change was made to the protocol as well. Server
1300 should not violate the protocol specification anymore.
1302 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1305 was tested. SOCKS4 was not but should work anyway.
