1 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new config entry [Identity] to fork the server and run
4 it as specific user and group. A patch from Bostik.
6 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * A big code auditing weekend happening. Auditing code for
9 obvious mistakes, bugs and errors. Also, removing any code
12 Removed files for being obsolete:
14 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
15 inline in the file lib/silcutil/silcbuffer.h)
17 o lib/silcutil/silcbufutil.c (the header has inline versions)
19 Changed code to fix possible error conditions:
21 o The buffer formatting routines now check that the destination
22 buffer really has enough space to add the data. This applies for
23 both buffer formatting and unformatting
24 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
25 unformatting was changed to accomodate following rules:
26 XXX_*STRING_ALLOC will allocate space for the data into the pointer
27 sent to the function while XXX_*STRING will not allocate or copy
28 the data into the buffer. Instead it sets the pointer from the
29 buffer into the pointer sent as argument (XXX_*STRING used to
30 require that the pointer must be allocated already). This change
31 makes this whole thing a bit more consistent and more optimized
32 (note that the data returned in the unformatting with XXX_*STRING
33 must not be freed now). The routines return now -1 on error.
35 o Tried to find all code that use buffer_format and buffer_unformat
36 and added return value checking to prevent formatting and
37 especially unformatting errors and possible subsequent fatal
40 o Changed ske->x and ske->KEY to mallocated pointers in
41 lib/silcske/silcske.h. Fixed possible data and memory leak.
43 o Added return value checking to all *_parse* functions. Fixed
44 many memory leaks as well.
46 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
47 so that buffer overflows would not happen. All code now also
48 checks the return value as it can fail.
50 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Added reconnection support to server if the normal server looses
53 its connection to the router (for example if router is rebooted).
54 The server performs normal reconnection strategy implemented
55 to the server. Affected file silcd/server.c.
57 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
59 * Added new packet type SILC_PACKET_SET_MODE that is used to
60 distribute the information about changed modes (for clients,
61 channels and clients channel modes) to all routers in the
62 network. Updated the protocol specification accordingly.
64 Added functions into silcd/packet_send.c and
65 silcd/packet_receive.c: silc_server_send_set_mode,
68 Added new files silcmode.[ch] into lib/silccore that implements
69 the encoding and decoding of Set Mode Payload. Added new type
70 SilcSetModePayload. Moved the definitions of different modes
71 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
73 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
75 * Oops, a little mistake in server's connection authentication
76 protocol. The protocol is not ended with FAILURE but with
77 SUCCESS if the authentication is Ok. :) Affected file is
80 * Implemented NICK_CHANGE notify handling in server in the file
81 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
82 the local clients on the channel. After the changing nickname
83 in router environment snhould work and the [<unknown>] nickname
84 should appear no more.
86 The silc_server_replace_id function that receives the Replace ID
87 payload now sends the NICK_CHANGE notify type also in the file
88 silcd/packet_receive.c
90 * Changed WHOIS and IDENTIFY command to support the maximum amount
91 of arguments defined in protocol specs (3328 arguments). This
92 fixed a bug that caused problems when there were more than three
95 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
97 * Added extra parameter, command identifier, to the
98 silc_client_send_command so that explicit command identifier
101 Changed that ID list routines uses specific command identifier
102 when sending WHOIS/IDENTIFY requests to the server so that they
103 can be identified when the reply comes back.
105 Affected files lib/silcclient/command.[ch],
106 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
108 * Added `sender' argument to silc_server_packet_send_to_channel
109 to indicaet the sender who originally sent the packet to us
110 that we are now re-sending. Ignored if NULL. Affected file
111 silcd/packet_send.[ch].
113 * Added some server statistics support in silcd/server_internal.h
114 SilcServerStatistics structure and around the server code. Also
115 send some nice statistics information when client is connecting
118 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
120 * Fixed channel ID decoding in server's JOIN command reply in
121 silcd/command_reply.c
123 * Fixed braodcasting of replace ID payload to not to send it if
124 we are standalone server in silcd/packet_receive.c.
126 * Fixed all channel message sending routines to not to send
127 packets to clients that has router set, since they are routed
128 separately in the same function earlier. Affects file
129 silcd/packet_send.c and all channel packet sending functions.
131 * In USERS reply, res_argv[i] are not allocated, the table
132 is allocated. Thus changed that free the table, not its
135 * In server's whois_check and identify_check if the client is
136 locally connected do not send any WHOIS commands - they are not
139 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Fixed some minor bugs in client when sending WHOIS command. The
142 arguments was in wrong order.
144 * Removed statis function add_to_channel from server in
145 silcd/command.c that was previously used with the joining but
148 * Tested USERS command in router environment successfully with two
149 routers, two servers and two clients.
151 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
153 * Reorganized the USERS command and command reply in client library
154 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
155 When the command is given by user we register a pending command
156 callback that will reprocess the command after the reply has been
157 received from the server. When reprocessing the packet we then
158 display the information. Thus, the USERS information is displayed
159 now in the command callback instead of in the command reply
160 callback. The processing of the command is same as previously
161 when server has sent the command reply in the JOINing process.
163 * Added to USERS command in silcd/command_reply.c to join the client,
164 we didn't use to know about, to the channel after we've created
165 a client entry for it. Also, for clienet we did know already still
166 check whether it is on the channel or not and add it if not.
168 * Removed silc_server_command_join_notify as the function and its
171 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
173 * Changed the client's pending command handling to the same as the
174 server's pending command handling. It is also now possible to
175 execute command reply functions from other command reply
176 function as the function callbacks for commands and command
177 replies are one and same. The pending commands are not static
178 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
179 in client connection context. Thus, pending commands are server
180 connection specific as it is convenient.
182 Changed the function silc_client_command_pending and
183 silc_client_command_pending_del and added new function
184 silc_client_command_pending_check. Removed the
185 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
188 * Added cmd_ident, current command identifier, to the client
189 connection context in lib/silcclient/client.h to keep track on
190 command identifiers used in command sending. Client's command reply
191 function handling now supports the mandatory command identifiers.
193 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
194 funtions in client to fully support pending command callbacks.
196 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
197 as one of the arguments to the application in the command reply
200 * NOTE: The FORWARDED flag is depracated. It used to be depracated
201 before first releasing SILC but came back. Now it is removed again
202 and should come back nomore. The FORWARDED flag was used only
203 by the JOINing procedure by forwarding the command packet to router.
204 Now, the JOINing procedure has been changed to more generic (due
205 to various router environment issues) and FORWARDED is not needed
206 anymore for anything. The protocol specification is yet to be
209 Now, removed silc_server_packet_forward from server and the flag
210 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
212 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
214 * Renamed NAMES command to USERS command. The NAMES was named that
215 due to historical reasons. Now it is renamed. Also, rewrote
216 parts of the USERS command. The nickname list is not sent anymore
217 by the server. Only Client ID and mode lists are sent in the USERS
218 command. Changed this also to the protocol specification.
220 The client now resolves the names and stuff after it receives
221 the USERS list from the server when joining to the channel.
223 * WHOIS and IDENTIFY commands has been changed to support multiple
224 Client ID's per command. One can now search for multiple users
225 in the network by sending only one WHOIS or IDENTIFY command.
226 Changed the code and the protocol specifications.
228 * Removed silc_server_command_identify_parse and changed that IDENTIFY
229 uses silc_server_command_whois_parse to parse the request. */
231 * If normal server, do not parse the WHOIS and IDENTIFY requests
232 before sending it to the router. Saves some time.
234 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Fixed JOIN command on client library. Wrong number of arguments
237 used to crash the client.
239 * Added silc_server_channel_has_global function to check whether
240 channel has global users or not.
242 * Added silc_server_channel_has_local function to check whether channel
243 has locally connected clients on the channel.
245 * The silc_server_remove_from_one_channel now checks whether the
246 channel has global users or not after given client was removed from
247 the channel. It also checks whether the channel has local clients
248 on the channel anymore. If it does not have then the channel entry
249 is removed as it is not needed anymore.
251 * The silc_server_notify now checks on JOIN notify whether the joining
252 client is one of locally connected or global. If it is global then
253 the channel has now global users on the channel and that is marked
254 to the channel entry. Also, it now saves the global client to
255 global list who is joining and JOINs it to the channel. This is
256 for normal server, that is.
258 Changed silc_server_send_notify_on_channel,
259 silc_server_packet_relay_to_channel and
260 silc_server_packet_send_to_channel check if we are normal server
261 and client has router set (ie. global client) do not send the
262 message to that client, as it is already routed to our router.
264 * Implemented LEAVE notify type handling in silc_server_notify
267 * Tested LEAVE command in router environment successfully. Tested
268 with two routers, two servers and two clients.
272 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
274 * Implemented SIGNOFF notify type handling in silc_server_notify
277 * silc_server_remove_id now removes the client entry from all channels
278 it has joined and thusly sends SIGNOFF notify type.
280 * Rewrote the NAMES list generation in server by removing two excess
281 loops. The lists are created now inside one loop.
283 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
285 * silc_server_remove_channel_user checks now also global list
286 for channel and client.
288 * silc_server_new_channel_user checks now both local and global
289 list for channel and client. Fixed a bug in client id decoding.
290 Used to decode wrong buffer.
292 * silc_server_channel_message checks now both local and global
293 list for channel entry.
295 * Tested channel joining (hence JOIN) in router environment
296 successfully. Tested with two routers, two servers and two
299 * Tested channel message sending in router environment successfully.
301 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
303 * Added silc_server_save_channel_key into server.[ch] to save the
304 received channel key in Channel Key payload processing. It is
305 also used in JOIN command reply handling.
307 Equivalent function silc_client_save_channel_key added into
308 client.[ch] into client library.
310 * Changed JOIN command reply to send information whether the channel
311 was created or not (is existing already) and the channel key
312 payload. Changed protocol specs accordingly.
314 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
315 the request was sent by ID and not by nickname. Crashed on
318 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
321 now correctly save the received data.
323 * silc_server_free_sock_user_data now notifies routers in the
324 network about entities leaving the network.
326 At the same time implemented functions silc_server_remove_id
327 and silc_server_send_remove_id to receive and send REMOVE_ID
328 packets. The packet is used to notify routers in the network
329 about leaving entities. The ID removed will become invalid in
332 * Added function silc_idlist_del_server into server. Removes and
333 free's server entry from ID list.
335 * silc_server_private_message function now checks, if we are router,
336 that the destination ID really is valid ID, naturally.
338 * In router when NEW_ID packet is received (for new client) the
339 hash of the Client ID is saved in the ID Cache but the
340 client->nickname is set to NULL, instead of putting the hash
343 IDENTIFY command now also checks that client->nickname must be
344 valid. If it is not if will request the data from the server who
345 owns the client. Added new function
346 silc_server_command_identify_check.
348 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
349 to set the command to already allocated Command Payload.
351 * Tested private message sending in router environment with two
352 routers, two servers and two clients. Fixed minor bugs and now
355 * Fixed segfault from client's NAMES command. Used to crash if
358 * Forwarded packets must not be routed even if it is not destined
359 to the receiver. Changed server code comply with this.
361 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added `require_reverse_mapping' boolean value to ServerParams
364 structure. If TRUE (not default) the server will require that
365 the connecting host has fully qualified domain name.
367 If the reverse mapping is not required and hostname could not be
368 found the IP address is used as hostname.
370 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Implemented version string checking to both client and server.
373 The check is incomplete currently due to the abnormal version
374 strings used in development version of SILC.
376 * Changed all command functions in server to use the new
379 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Changed char *data to unsigned char *data in ID Cache system to
382 support binary data as ID Cache data. Changed code to support
383 binary data in lib/silccore/idcache.c.
385 * Renamed silc_server_packet_relay_command_reply to
386 silc_server_command_reply as it is normal packet receiving
387 function. Rewrote the function to accept command replys for
388 servers and not only for clients.
390 * Mark remote router always as registered server if we are connecting
391 to it. Otherwise, commands sent by the router to us are ignored.
393 * All ID List find routines now returns the ID Cache Entry pointer
394 as well if requested.
396 * WHOIS command works now in router environment, tested with two
397 routers, two servers and two clients.
399 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
400 in router environment (as it is almost equivalent to WHOIS) but
401 hasn't been tested thoroughly. Added new functions:
403 silc_server_command_identify_parse
404 silc_server_command_identify_send_reply
405 silc_server_command_identify_from_client
406 silc_server_command_identify_from_server
408 * Disabled route cache adding because adding two different ID's with
409 same IP replaces the old cache entry thus giving wrong route.
410 The entry->router->connection is always the fastest route anyway
411 so route cache may not be needed. Of course, new routes maybe
412 established after receiving the ID when the entry->router->connection
413 might not be anymore the most optimal.
415 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Add route cache for received ID for fast routing.
419 * Added silc_server_packet_route to route received packet on router
420 that is not destined to us.
422 * Renamed silc_server_get_route to silc_server_route_get.
424 * Added id_string and id_string_len fields into SilcServer to
425 include encoded ServerID for fast comparing without excess
426 encoding of the ID's.
428 * Cleaned up WHOIS command on server side. Added following static
431 silc_server_command_whois_parse
432 silc_server_command_whois_check
433 silc_server_command_whois_send_reply
434 silc_server_command_whois_from_client
435 silc_server_command_whois_from_server
437 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
438 arguments in command replies. All command functions should be
439 updated to use this macro.
441 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
443 * Minor typo fixes on command reply handling on server.
445 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * Added silc_server_command_add_to_channel internal routine to add
448 the client to the channel after router has created the channel and
449 sent command reply to the server.
451 * Added generic silc_server_send_command to send any command from
454 * Use static buffer with ID rendering instead of duplicating data.
456 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * Fixed a channel user mode bug when joining to a channel server gave
459 everybody channel founder rights, oops.
461 * We mark ourselves as the router of the incoming server connection
462 if we are router ourselves. This way we can check in some packet
463 sending functions whether it is locally connected server. For
464 incoming router connections we put NULL.
466 * For router sending packets locally means now always sending the
467 packet cell wide; to local clients and local servers. For normal
468 server sending packet locally means sending it to only local
471 * Fixed the JOIN command to really work in router environment. If the
472 channel is created it is always created by the router. Router is
473 also responsible of making the initial joining to the channel,
474 sending JOIN notify to the sending server and distributing
475 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
476 does not exist server doesn't do anything else but forward the
477 command to the router which performs everything.
479 * Added silc_server_send_channel_key function to send the Channel Key
482 * Added silc_server_create_channel_key to create new channel key. The
483 channel key is now re-generated everytime someone joins or leaves
484 a channel, as protocol dictates. Note: channel->key_len is the
487 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * Splitted server.[ch] finally. Created now packet_send.[ch] and
490 packet_receive.[ch] to separate packet sending and receiving
491 routines. The server.[ch] now includes everything else including
492 actual packet processing (writing and reading data) and other
495 Renamed silc_server_private_message_send_internal to
496 silc_server_send_private_message. The routine is still though
497 used only to relay private messages as server does not send
498 private messages itself.
500 Renamed silc_server_new_channel to silc_server_create_new_channel
501 and added new function sicl_server_new_channel that handles the
502 incoming New Channel packet. Added also new sending function
503 silc_server_send_new_channel to send New Channel Payload.
505 * Added new function silc_server_notify to process incoming notify
506 packet to the server/router. Server may then relay the notify
507 to clients if needed.
509 * Added new function silc_server_new_channel_user to process incoming
510 New Channel User packet. Router will redistribute the packet and
511 send JOIN notify to its local clients and locally connected servers
512 if needed. Normal server will send JOIN notify to its local client
513 on same channel when received this packet. Added also corresponding
514 sending function silc_server_send_new_channel_user to sent the
517 * Added boolean route argument to send_notif_to_channel and
518 packet_send_to_channel functions to attempt to route the packet
519 if it is TRUE and send only locally if it is FALSE.
521 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
523 * silc_server_replace_id now broadcasts the received replace ID
524 packet if it is not broadcast packet already. The router must
525 broadcast to inform other routers about changed ID.
527 * Added backpointer to server's router into SilcServer context in
528 silcd/server_internal.h.
530 * Fixed silc_server_packet_broadcast to send correct broadcast
533 * The channel key is now distributed to the local client as soon
534 as it is received from the router (in router environment) so that
535 no other packet may be sent for the channel until client has
538 * silc_server_remove_channel_user now broadcasts the received
539 Remove Channel User packet if it is not broadcast packet already.
540 The router must broadcast to inform other routers about removed
543 * Added users field into SilcPacketContext that is a reference count
544 of the context. One can increase the reference count by calling
545 silc_packet_context_dup which is now changed to just increase the
546 reference count instead of duplicating the data. The reference
547 count is decresed by calling silc_packet_context_free that will
548 free the data after the reference count hits zero.
550 For now on the packet context and everything allocated into it
551 (including the raw packet from network) must be freed by calling
552 the new silc_packet_context_free function. Added also new function
553 silc_packet_context_alloc that must be used now to allocate the
554 context. This also means that if a routine is asynchronous from
555 silc_[client/server]_packet_parse_type the packet context must
556 be duplicated by calling silc_packet_context_dup. Otherwise it
557 gets free'd after silc_[client/server]_packet_parse_type returns.
558 Also, one must remember that if packet is duplicated then its
559 reference count must be decresed by calling the free function as
560 many times as it was duplicated.
562 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
563 from both client and server.
565 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
567 * Made joining to a channel working in router environment.
569 * Cleaned up JOIN command on server side and create function
570 silc_server_command_join_channel internal routine to make the
573 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * Changed silc_command_pending list to SilcDList. Also, added
576 `ident' field to SilcServerCommandPending structure to identify
577 the reply and to call correct callback.
579 Added silc_server_command_pending_check function to replace the
580 corresnponding macro. The silc_command_pending list is not
583 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
584 to set identifier to previously allocated Command Payload. It
585 is used to set identifier for command when resending Command
588 * Added silc_command_payload_encode_payload to encode Command
589 Payload buffer from SilcCommandPayload structure.
591 * Added silc_argument_payload_encode_payload to encode Argument
592 payload buffer from SilcArgumentPayload structure.
594 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
596 * Changed WHOIS command to support router connection on server side.
597 The whois request is always sent to router unless the server is
598 standalone server. After server has received the reply from the
599 router will it send the reply to the client.
601 * Added silc_server_packet_broadcast into silcd/server.[ch] to
602 broadcast received broadcast packet. The function is used only
603 by router. The broadcast packet is always sent to the router's
606 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
607 render given ID to printable string, for log files for example.
609 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
611 * Made basic router to router connections working. At least they
612 can now connect to each other but nothing really works the way
613 they are supposed - yet.
615 * Added new initiator token to RouterConnection configuration
616 file in silcd/serverconfig.[ch]. It is used to tell whether we
617 are the initiator to the remote router or whether we'll expect
618 the other end to connect.
620 * Moved registering of listener task to silc_server_init, hence
621 the server starts listenning as soon as it is run, even if it
622 does not have connections to other routers. Let's see how well
625 * Changed default connection retry timeouts for more suitable in
628 * Removed cipher and such arguments from silc_idlist_add_client
629 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
630 Added new function silc_idlist_add_data to add the keys and stuff
633 * Added SilcIDListData structure and added it to SilcClientEntry
634 and SilcServerEntry as their first field in the structure. This
635 way we can explicitly cast the ID entries to the SilcIDListData
636 structure and get common data for the entries. In past, we had
637 to first check what type of connection it is and then cast it to
638 correct ID entry type. Now, we can directly cast the opaque
639 pointer to the SilcIDListData (no matter what ID entry it actually
640 is) and get the data needed.
642 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Wow, found a bug in scheduler. The scheduler uninitialized itself
645 in some circumstances even if threre were timeout tasks, though not
646 IO tasks, but tasks anyway. Now fixed.
648 * Defined SilcServerConnection structure to hold connection specific
649 stuff about directly connected servers and routers. The definition
650 is currently in silcd/server_internal.h. I thought about having
651 a bit more important role fro this struct but for now it is used
652 only when connecting to other server (or router actually).
654 * Added connecting retry support in server when connecting to
655 router(s). The retry feature implement exponential backoff
656 algorithm. Also, added SilcServerParams structure to hold default
657 parameters for server. For now, it include these retry settings
658 and are hard coded. After server is moded to be as Silc Server
659 Library this structure will be more important.
661 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Changed client librarys channel->clients table to SilcList and
664 changed code accordingly.
666 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Changed client's channel table to SilcList and changed code
669 accordingly. Also changed SilcChannelClientEntry to include back-
670 pointer to the channel so that client entry can use that structure
671 as list as well and we have fast cross-reference to the channel.
672 This change dramatically decreased the complexity of channel
673 handling with client entry and vice versa (removed one extra
674 loop when searching for channel entry from many functions).
676 * Changed server->sim from table to SilcDList and changed code
679 * NAMES command can now be used from user interface. It will show
680 the user list on the channel, neatly.
682 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
683 Code now saves realname of the user if it becomes available.
685 * Renamed configure.in to configure.in.pre and made ./prepare
686 script to automatically add correct version string to
687 configure.in which it creates from configure.in.pre.
689 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * NAMES command reply now shows users mode with the nickname when
694 * Moved silc_client_ch[u]mode[_char] functions from
695 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
696 place sucks, they are utility functions and should be in some
699 * Fixed some unsigned int's to unsigned short's. Patch by cras.
701 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
704 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Added TRQ (efficient deque and list library) into lib/trq. This is
709 a very good list library that is currently used in the SILC. Defined
710 SilcList API over the library because I didn't like the API very
711 much. See lib/trq/silclist.h for the API and examples of how to
712 use the API. Fixed various places in the code to use the new
713 SilcList API. The SilcList is meant for lists that has a structure
714 already defined as a list. It is not suitable to add just some
715 context to the list (in TRQ, the context is the list actually).
717 So, I defined SilcDList that can be used for the purpose where
718 predefined list structure does not exit. This can be used as
719 such list. Now some context just can be added to the SilcDList.
720 Currently this list is not used in the SILC just yet, though there
721 are a lot places where this can replace dynamically allocated
722 tables and I will fix these places, later, to use SilcDList.
723 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
724 and use TRQ internally).
726 Also fixed some annoying warning messages that the original TRQ
727 code generated. Also minor changes to TRQ's Makefile.in.
729 * Added support for querying by Client ID to both WHOIS and
730 IDENTIFY commands into server, as required by the protocol.
732 * Removed method function pointers from SilcBuffer structure. They
733 weren't used to anything and just increased the context size for
734 no good reason. This change also made silc_buffer_alloc and
735 silc_buffer_free functions inline functions.
737 * Disabled command flooding detection support until it's fixed so
738 that it accepts commands in but does not execute them more than once
741 * Added silc_net_localhost(), to return local hostname, into
742 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
743 that must be initialized before calling silc_client_init.
745 * Added new function: silc_server_send_notify_on_channels to send
746 notify messages to all channels client has joined. It is assured
747 that the message is sent only once per client.
749 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
750 lib/silcutil/silcutil.[ch] as silc_format function. The new
751 function is generic and is used by server as well, not only by
752 the logging routines.
754 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
755 the provided version string was not acceptable. Added new function:
756 silc_ske_check_version into lib/silcske/silcske.h. The function
757 must be implemented by the application (client or server) and it
758 does not reside in the SKE library. The function checks the version
759 string remote end sent.
761 * Added back pointers (to opaque context and to SilcSocketConnection)
762 into SilcPacketContext structure into lib/silccore/silcpacket.h.
764 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
765 duplicate packet context structure.
767 * Changed `notify' client operation to send same arguments as client
768 receives from server except for ID's. ID's are mapped to correct
769 ID entry and that is returned. Also, if channel entry is not sent
770 by server but the notify is for channel the channel entry is sent
771 to application (otherwise application doesn't know that it is for
772 channel (library gets it from packet's Destination ID)).
774 * Added silc_client_remove_from_channels into client library to
775 remove a client from all channels it has joined to. Used when
776 received SIGNOFF notify from server. Added also new function
777 silc_client_replace_from_channels to replace old ID entry with
778 new ID entry on all channels. Used when received NICK_CHANGE
781 * Fixed ID Cache list handling in silc_idlist_get_client in
782 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
783 to get (or query) client by ID.
787 * Added connection authentication status message defined by the
788 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
789 support for these into the code in client and server side.
791 * Added generic function silc_client_send_command to send any command
792 with variable argument list. Application should use this function
793 to send commands if the command functions provided by the library
794 does not suite for the application's user interface needs.
796 * Added new `failure' client operation. Application is notified about
797 received failure packet if client is executing a protocol. In this
798 case the protocol's execution has failed.
800 * Added SKE's end notify to send the SKE_SUCCESS notify message that
801 is required by the protocol.
803 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
804 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
807 * Added status flag to SilcSKE object to indicate realtime status
810 * Application receives now exactly same command reply arguments as
811 the library receives from server. However, if ID is received the
812 corresponding ID entry is returned to the application (eg. Client
813 ID is mapped to correct SilcClientEntry entry and that is returned).
814 Changed command_reply client operation due to this change.
816 * Changed all ID's in commands and in command replys as ID Payloads.
817 Change affected both client and server side codes.
819 All ID's sent in SILC network (with execption of ID's in SILC
820 Packet header) are sent in ID Payload to support variable length
823 * Server now notifies nick changes and notifies all clients on
824 the channels about the new nickname (about the new Client ID,
827 * Implemented CMODE command to change channel modes. Supports all
828 channel modes defined by the protocol specs except ban and invite
829 lists. (Also, private channel key mode is supported but support for
830 setting private channel key in client is missing, thus, this mode
831 has no effect on client side (except that server requires that the
832 client uses private channel key and normal channel traffic does not
835 Also, invite mode works per se, but INVITE command does not work
836 yet correctly, so you can set channel as invite only channel but
837 inviting clients to the channel does not work (it is yet to be
838 thought what's the best way to do it).
840 * Added new command SILC_COMMAND_CUMODE to change user mode on the
841 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
842 Implemented CUMODE command to change user's mode on the channel.
843 Supports all modes defined by the protocol specs.
845 * Added NAMES command reply to return users modes on the channel.
847 * Removed unnecessary and slow ciphers from lib/silccrypt.
849 * Set SO_KEEPALIVE option to connection sockets by default.
851 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
853 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
854 redefined the Notify Payload into protocol specs.
856 * Added silc_id_payload_parse_id to get ID directly from raw
859 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
862 accept searching by Client ID as well.
864 * Added support for LEAVE and SIGNOFF notify types in client library.
866 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
867 to parse ID Payload from raw data.
869 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
871 * Added flags parameter into silc_ske_assemble_security_properties
872 function in lib/silcske/silcske.[ch].
874 * Changed notify client operation to fit better for notify messages
875 sent by server. The notify payload received from server is now
876 passed to the application (after parsing it to SilcNotifyPayload).
877 It is application's responsibility to retrieve the arguments
878 from the payload and show the message the way it wants. The message
879 sent by server is implementation specific.
881 * Changed public keys to comply with the protocol specification.
882 Old public keys are not supported anymore and are not compatible.
884 * Removed nickname from Channel Payload as the latest draft removed
885 it. The client must resolve the nickname from the NAMES command
886 reply received when it joined the channel.
888 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
890 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
892 * Fixed some errors in protocol specification drafts.
894 * Created lib/silccore/silcnotify.c to implement Notify Payload
895 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
896 generic payloads described by protocol specifications. The file
897 includes implementations for ID Payload and Argument Payload.
899 * Changed Command Payload implementation to use the new Argument
900 Payload. Changed command_xxxx_payload to command_payload_xxxx
901 to comply with SILC coding conventions.
903 * Added suppport for Argument Payload handling in Notify Payload
904 implementation as protocol requires it. Added the new support
905 into server and client lib as well.
907 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Added support for multiple nicknames on same channel. [n] is
910 added locally to the nickname if there are more than one same
911 nicknames on the channel.
913 * Server now sends all nicknames that matched WHOIS request.
914 Client also shows the list received from server.
916 * Added TOPIC command to client side. User can now set and show
917 current topic on channel.
919 * Added MOTD command to client and server. Also, server sends the
920 motd when client connects to the server.
922 * Changed version strings to comply ISO 8601.
924 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Fixed protocol error handling in client library. It should now
927 cope even if the SKE fails for some reason.
929 * Made new protocol specification drafts for submitting to IETF.
931 * Implemented TOPIC command to server in silcd/command.c.
933 * Added two new notify types into lib/silccore/silcnotify.h:
934 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
935 notify nickname change and topic setting/change on a channel.
937 * API change of command_reply operation in client library. The
938 application gets now the status type received from server as well.
940 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Removed the function just added to lib/silcutil/silcschedule.[ch].
944 * Cras fixed and optimized the packet handling even further and
945 it should work now. Minor change to the prototype of function
946 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
948 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
950 * Added new function into lib/silcutil/silcschedule.[ch]:
951 silc_schedule_with_fd to select() a specified fd. The function
952 returns after timeout expires or data arrives or goes. The
953 function is used by packet routines to wait that all data is
954 received from network.
956 * Fixed data reading from network in lib/silccore/silcpacket.c.
957 The code now assures that all data is read from the fd and then
958 continues packet processing. This was a bug fix since the code
959 used to drop some data in some circumstances.
961 * Added new function into lib/silcclient/client.[ch]:
962 silc_client_start_key_exchange to start key exchange after
963 connection has been established to server. The code internally
964 now uses this funtion but its main purpose was to provide it
965 for applications that perform their own connecting. After
966 application has created a connection it merely calls this
967 function to start the key exchange between client and server.
968 The library takes care of everything else after that.
970 Updated also lib/silcclient/README to explain the usage of
973 * Do not send to application information that connection has
974 been established. Application gets notified it by connect
977 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Applied cras's patch to add silc_schedule_one function. The
980 function runs scheduler once and returns.
982 * Fixed the scheduler after cras messed it up. The timeout
983 handling works now as it's supposed to work.
985 * Added into lib/silccore/ silcnotify.h to include notify
986 message types support. Changed silc_server_send_notify*
987 functions, in server.[ch], to support those new notify types.
988 Added the support for the notify types into client library,
989 as well. Added new notify client operation into ops.h in
992 * Changed silc_server_packet_send_to_channel to send normal
993 packets instead of just channel message packets. The function
994 is now used to send the notify packets to channels. It is not
995 used to send channel message packets anymore, as server never
998 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
999 va_arg()s as it seems to require it nowadays. I guess, if SILC
1000 is compiled with older va_arg() the new code should work anyway.
1002 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1004 * Splitted core library. Core library (lib/silccore) includes
1005 now only SILC protocol specific core (and common) components.
1006 Created new utility library (lib/silcutil) that includes more
1007 generic purpose stuff. The stuff for util library was taken
1008 from the old core library. This was minor and easy split.
1010 * Created SILC Client Library (lib/silcclient) that includes
1011 implementation of the SILC client without user interface. This
1012 was major move from silc/ directory. The code has been changed
1013 so that it is transparent towards the user interface. The
1014 silc/ directory includes now the same user interface as before
1015 and it uses the new client library. Read lib/silcclient/README.
1016 Basicly, the client library performs everything else related
1017 to SILC except user interface handling. Also, configuration
1018 files are considered to be part of user interface and library
1019 does not handle them.
1021 This change also changed a lot of structures, function naming etc.
1022 Most important change was that SilcClientWindow object was
1023 renamed to SilcClientConnection in the client library. Created
1024 also new file lib/silcclient/ops.h. Also added new files
1025 silc/local_command.[ch] and silc/client_ops.[ch].
1027 All these changes were made to make it easier for user interface
1028 designers to create what ever user interface for the SILC client
1031 It is also expected that the server will be moved to lib
1032 directory as well and SILC Server Library will be created;
1033 sometimes in the future.
1035 * Removed Local commands from lib/silccore/silccommand.h as
1036 they are application specific and new client library does not
1037 handle any of those anymore.
1039 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1040 old client implementation in silc/.
1042 * Added support for callback functions in SILC_LOG_* macros.
1043 Application can now set its own callbacks that will be called
1044 instead of using the default functions that will always print
1045 the debug messages to stderr (or stdout). Also, debugging can
1046 now be disabled by setting silc_debug to FALSE and re-enabled by
1047 setting it to TRUE. Note, that logging will still work even
1048 if debugging is disabled.
1050 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1051 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1052 silc_log_reset_debug_callbacks.
1054 * To enable debugging in silc client one must give now -d
1055 option on command line.
1057 * Changed silc_schedule_init to automatically allocate task queues
1058 if they are not allocated before calling it.
1060 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1062 * Added GMP 3.1 into math library.
1064 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1067 a channel in SILC network. The packet is used by servers and
1068 routers to notify other routers that user has left a channel.
1069 This little feature was missing until now. Added the feature
1070 to protocol specification as well.
1072 Added functions: silc_server_send_remove_channel_user and
1073 silc_server_remove_channel_user into server.[ch].
1075 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1076 lib/silccore/silcpacket.h. However, they are not implemented
1079 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1081 * Fixed joining to a channel and sending channel messages
1082 between server and router. The channel message sending should
1083 now work inside a cell.
1085 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Fixed the private message sending between server and router.
1088 The private message sending should now work inside a cell.
1090 * Added silc_server_replace_id into server.[ch] to replace
1091 existing ID in the SILC network.
1093 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1094 and silc_idlist_replace_server_id into idlist.[ch] in server.
1096 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1098 * Fixed the server to server connections. Server can again now
1099 connect to router. Router to router connections probably does
1102 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added dynamic protocol registering support. Now protocols can
1105 registered and unregistered on the fly. Patch by cras.
1107 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1109 * Added lib/contrib directory to hold routines that some platforms
1110 don't have but are needed by SILC.
1112 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1113 into lin/contrib to provide getopt() and getopt_long() for
1114 those who don't have it.
1116 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1118 * Added AWAY command to client. When away message is set and
1119 client receives a private message packet the client automatically
1120 replies to the sender with the away message.
1122 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1123 bug seemed to be the cause of recent problems when compiling
1126 * Added version detection support to SKE protocol specification
1127 and added the new changes to the SKE implementation as well.
1128 There were other minor changes in the SKE protocol as well.
1130 Many changes in lib/silcske/silcske.[ch] and in
1131 lib/silcske/payload.[ch].
1133 * Added ^U functionality, clear input line. Patch from cras.
1135 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Mainly small bugfixes on core library. Fixed some debugging
1138 logging and buffer overflow in silclog.c.
1140 * Updated config.sub and config.guess on the distribution tree.
1142 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Added command lagging support in server. Client may execute
1145 commands now only once in two seconds.
1147 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Optimized packet reception. MAC computation and checking is now
1150 also more optimized. A lot previously duplicated code is now
1151 used as generic by both client and server.
1153 * Fixed key pair generation in clientutil.c
1155 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Added into lib/silccore/silcbufutil.[ch] new function;
1158 silc_buffer_realloc.
1160 * Moved generic packet sending/encryption functions to
1161 lib/silccore/silcpacket.[ch] from client and server. Some
1162 rewriting of the functions.
1164 * Moved all generic packet reception/decryption functions to
1165 lib/silccore/silcpacket.[ch] from client and server. The
1166 packet processing is now much cleaner in both client and server.
1167 These were major changes in both client and server.
1169 * Created many common functions in server to do packet sending.
1170 Previously code were duplicated a lot, this has been removed
1173 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Rewrote major parts of the ID cache system. Don't know
1176 whether it is better now or not but at least the API is more
1179 * Major rewrite on ID cache stuff on client because of the ID
1180 cache API changes. Added idlist.c to client.
1182 * Also major rewrite on ID cache stuff on server as well.
1183 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1184 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1185 in hand, instead they are all put into the ID cache system now.
1186 All server_idlist_* routines uses ID cache now instead of
1187 traversing its own lists (those lists does not exist anymore).
1188 SilcIDList though still exists. Also, SilcXXXEntry's are
1191 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * Finally made the SKE implementation compliant to the protocol
1194 specification. All mp integers are now binary encoded as
1195 opposed being HEX encoded.
1197 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1200 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1201 functions: silc_[encode/decode]_pem. Also added function
1202 silc_encode_pem_file to PEM encode with newlines ('\n') for
1205 * SILC public keys are now encoded either PEM or binary. Same
1206 option is for private keys as well. By default private keys
1207 are binary encoded and public keys PEM encoded. Silly HEX
1208 encoding were removed.
1210 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1211 function to create fingerprints.
1213 * Fixed a bug in SHA1; does not change the original data anymore.
1215 * Partly implemented INFO command on client and server side.
1216 Fixed CLEAR command. Changes to SERVER command; show current
1217 server(s) when giving command without arguments. Added
1218 VERSION command to client.
1220 * Added check to server that unregistered connections cannot
1221 execute commands (unless it is specificly allowed).
1223 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Fixed screen refresh.
1227 * Fixed channel joining bug from client. On some circumstances
1228 client tried to join to a channel it had already joined.
1230 * Added public key verification process into client's protocol.c.
1231 The client now verifies the public key from user and saves
1232 it into ~./silc/serverkeys/ directory.
1234 Added into: clientutil.[ch]: silc_client_verify_server_key.
1236 * Changed SKE protocol's silc_ske_initiator_finish function
1237 to accept callback function that verifies the received public
1238 key. Removed old silc_ske_verify_public_key function.
1240 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1242 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1243 silc_pkcs_private_key[_data]_set.
1245 * Made the password and public authentication more cleaner in
1246 server's protocol.c.
1248 * Removed historic and obsolete protocol `channel_auth' from
1249 both client and server.
1251 * Removed wrong way of sending command status messages from
1252 server to client in server's command.c. The old way violated
1253 protocol specification.
1255 Changes to silccore/silccommand.[ch]: removed
1256 silc_command_encode_status_payload -> not needed anymore,
1257 changed silc_command_encode_payload_va to accept extra
1258 argument on variable argument list. The argument type must
1259 now be provided to the function. Also, added new function:
1260 silc_command_encode_reply_payload_va which is same as
1261 normal command_encode_payload_va except command status type
1262 is provided as extra argument.
1264 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * Added ~./silc directory handling. The directory includes the
1267 public and private keys for the client.
1269 Added silc_client_check_silc_dir, silc_client_create_identifier
1270 and silc_client_load_keys.
1272 * Implemented SILC protocol compliant public key. Added public
1273 and private key saving to and loading from files.
1275 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1276 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1277 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1278 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1279 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1281 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1282 silc_pkcs_load_[public/private]_key.
1284 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Added silc_server_get_route (route.[ch]) to get connection
1287 data for the fastest route for given ID.
1289 * Implemented INVITE command on client and server. The command
1290 were re-defined in the SILC Protocol Specification and the
1291 implementation now complies with the specification.
1293 * Implemented PING command on client and server.
1295 * Implemented NAMES command on client and server. The server side
1296 supports currently only normal server not router server yet.
1297 Some changes to NAMES definition in SILC protocol specification.
1299 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1301 * Implemented LEAVE command on client and server.
1303 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1304 again. This change was made to the protocol as well. Server
1305 should not violate the protocol specification anymore.
1307 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1309 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1310 was tested. SOCKS4 was not but should work anyway.
