1 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added silc_ske_process_key_material_data as generic routine
4 to process any key material as the SILC protocol dictates. The
5 function is used by the actual SKE library but can be used by
6 applications as well. This relates to the private message keys
7 and the channel private keys since they must be processed the
8 same way the normal SILC session keys. The protocol dictates
9 this. Affected files: lib/silcske/silcske.[ch].
11 Added also silc_ske_free_key_material to free the
12 SilcSKEKeyMaterial structure.
14 * Defined silc_cipher_set_key function to set the key for
15 cipher without using the object's method function. The affected
16 files: lib/silccrypt/silccipher.[ch].
18 * Implemented silc silc_client_add_private_message_key,
19 silc_client_add_private_message_key_ske,
20 silc_client_del_private_message_key,
21 silc_client_list_private_message_keys and
22 silc_client_free_private_message_keys functions in the
25 Added functions silc_client_send_private_message_key to send
26 the Private Message Key payload and silc_client_private_message_key
27 to handle incoming Private Message Key payload.
29 * Added Cipher field to the Private Message Key payload to set
30 the cipher to be used. If ignored, the default cipher defined
31 in the SILC protocol (aes-256-cbc) is used.
33 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
35 * Removed lib/silcclient/ops.h file.
37 Redefined parts of the SILC Client Library API. Created new
38 file silcapi.h that deprecates the ops.h file and defines the
39 published Client Library API. Defined also private message key
40 API and channel private key API into the file.
42 This is the file that the application must include from the
43 SILC Client Library. Other files need not be included by
44 the application anymore.
46 * Added new key_agreement client operation callback and also
47 defined the Key Agreement library API for the application.
49 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
51 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
52 is used by clients to request key negotiation between another
53 client in the SILC network. If the negotiation is started it
54 is performed using the SKE protocol. The result of the
55 negotiation, the secret key material, can be used for example
56 as private message key.
58 Implemented the Key Agreement payload into the files
59 lib/silccore/silauth.[ch].
61 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * Redefined ciphers for the SILC protocol. Added some new ciphers
64 and defined the key lengths for the algorithms. Changed the
65 code accordingly. The default key length is now 256 bits.
67 * Fixed SKE key distribution function silc_ske_process_key_material
68 when the key length is more than 128 bits. The default key
69 length in SILC is now 256 bits.
71 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
72 to indicate unsupported algorithm.
74 * Renamed rijndael.c to aes.c and all functions as well.
76 * Fixed a long standing channel key setting bug in client library.
77 Weird that it has never surfaced before.
79 * Fixed bug in channel deletion. If the entire channel is removed
80 then it must also delete the references of the channel entry
81 from the client's channel list as the client's channel entry and
82 the channel's client entry share same memory.
84 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Implemented CONNECT and SHUTDOWN commands in the client.
88 * Implemented CLOSE command to the client.
90 * Added the function silc_idlist_find_server_by_name into the
91 files silcd/idlist.[ch].
93 Added the function silc_idlist_find_server_by_conn into the
94 files silcd/idlist.[ch].
96 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * DIE command was renamed to SHUTDOWN. Updated the both code
101 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
102 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
104 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
107 * Added function silc_server_create_connection function to create
108 connection to remote router. My server implementation actually
109 does not allow router to connect to normal server (it expects
110 that normal server always initiates the connection to the router)
111 so the CONNECT command is only good for connecting to another
114 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
116 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
117 or some other client was kicked from the channel.
119 Implemented the handling of the notify type to both client
122 Implemented silc_server_send_notify_kicked to send the KICKED
123 notify. It is used to send it to the server's primary router.
125 * Implemented the KICK command into server and client.
127 * Added `query' argument to the silc_idlist_get_client function
128 to indicate whether to query the client from server or not if
131 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
132 to indicate that the client is not channel founder.
136 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
138 * Removed the rng context from SilcPacketContext structure and
139 changed that the packet routine uses the Global RNG API.
141 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Added support for quit message that client can "leave" on the
144 channel when it quits the SILC. It is ditributed inside the
145 SILC_NOTIFY_TYPE_SIGNOFF notify type.
147 Added silc_server_free_client_data that will take the
148 signoff message as argument.
150 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
152 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
154 * Updated parts of the protocol specification to keep it up
157 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
159 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
160 payloads in one packet.
162 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
163 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
164 use now the new List flag.
166 * Also deprecated the following packet types: REPLACE_ID,
167 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
169 * Added list support for Notify packet in server.
171 * Added silc_server_send_notify_channel_change to send the
172 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
173 the silc_server_send_replace_id.
175 * Added silc_server_send_notify_nick_change to send the
176 NICK_CHANGE notify type. Deprecates the function
177 silc_server_send_replace_id.
179 * Added silc_server_send_notify_join to send the JOIN notify type.
180 Deprecates the function silc_server_send_new_channel_user.
182 * Added silc_server_send_notify_leave to send LEAVE notify type.
183 Deprecates the function silc_server_send_remove_channel_user.
185 * Added silc_server_send_notify_cmode and
186 silc_server_send_notify_cumode to send CMODE and CUMODE notify
187 types. Deprecates the silc_server_send_set_mode function.
189 * Added SERVER_SIGNOFF notify type to indicate that server has
190 quit. This means that all clients on the channel from that
191 server will drop. This can be also used when netsplit happens.
193 Deprecated REMOVE_ID packet type since it is not needed anymore
196 Added silc_server_send_notify_server_signoff to send the
197 SERVER_SIGNOFF notify type. Deprecates the function
198 silc_server_send_remove_id.
200 Added also silc_server_send_notify_signoff to send the
203 * Employed the PKCS #1. It is the mandatory way to do RSA in the
204 SILC protocol from this day on. Changed the protocol
205 specification as well.
207 * Added silc_server_send_notify_topic_set to send TOPIC_SET
208 notify type. It is used between routers to notify about
209 topic changes on a channel.
211 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
214 * Partly updated the protocol specification to comply with the
215 changes now made. It is still though a bit outdated.
217 * The JOIN notify type now takes one extra argument <Channel ID>.
218 The packet used to be destined to the channel but now the
219 JOIN type may be sent as list thus it is impossible to
220 destine it to any specific channel. By adding this argument
221 it is again possible.
223 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Added CREDITS file. The CHANGES and CREDITS file will appear
226 in the distribution as well.
228 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
231 types in the server's silcd/packet_receive.c.
233 * Implemented CMODE and CUMODE to work in router environment.
235 * Fixed minor encoding and decoding buglet from the
236 lib/silccore/silcmode.c.
238 * Fixed buffer overflow from lib/silcclient/command.c in USERS
241 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
243 * Changed all SilcConfigServer* and silc_config_server* to
244 SilcServerConfig* and silc_server_config*, respectively.
247 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
249 * Associated the ID (client or server ID) to the Authentication
250 Payload to avoid any possibility of forging. Updated the
251 protocol specification and the code accordingly.
253 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * The RSA key length is now save to the RsaKey context in the
256 key generation process in lib/silccrypt/rsa.c. The key length
257 is now used to figure out the maximum size of the block allowed
258 to be encrypted/signed.
260 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
261 is equivalent to the silc_mp_mp2bin but does not allocate any
264 * Changed silc_mp_mp2bin API to take length argument. If it is
265 non-zero then the buffer is allocated that large. If zero, then
266 the size is approximated using silc_mp_sizeinbase, which however
269 * Created Global RNG API which is global RNG that application can
270 initialize. After initializing, any routine anywhere in the
271 code (including library) can use RNG without allocating a new
272 RNG object. This was done to allow this sort of use of the
273 RNG in code that has no chance to allocate RNG object. All
274 applications currently allocate this and many routines in the
275 library use this. Affected file lib/silccrypt/silcrng.[ch].
277 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
278 it to use the Global RNG API.
280 * Defined Authentication Payload into protocol specification that
281 is used during SILC session to authenticate entities. It is
282 used for example by client to authenticate itself to the server
283 to obtain server operator privileges.
285 Implemented this payload into the lib/silccore/silcauth.[ch].
286 Implemented also routines for public key based authentication
287 as the new protocol specification dictates.
289 Moved definitions of different authentication methods from
290 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
292 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
293 silc_pkcs_verify and silc_pkcs_sign_with_hash and
294 silc_pkcs_verify_with_hash functions into the file
295 lib/silccrypt/silcpkcs.[ch].
297 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
299 * The client entry's userinfo pointer must be always valid.
300 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
301 will fail since it requires the userinfo. Now, the userinfo
302 is allocated as "" if actual userinfo does not exist. Actually,
303 it must exist and it is totally Ok to drop client connections
304 that does not announce the userinfo. However, we will make
305 this workaround for now.
307 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
308 to return the remote port by socket.
310 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
312 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
313 SILC_SERVER_PENDING_EXEC and added an new macro
314 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
315 data or when error occurs while processing the pending command.
317 Added new argument `destructor' into silc_server_command_pending
318 and to the SilcServerCommandPending object. This destructor is
319 now called after calling the pending callback or if error occurs
320 immediately. If error occurs the actual pending callback won't
321 be called at all - only the destructor. The destructor may be
322 NULL if destructor is not needed.
324 All this applies for client library code as well. Similar
325 changes were made there as well for the pending commands.
327 In the client, the application must now allocate the
328 SilcClientCommandContext with the silc_client_command_alloc
331 * Added reference counter to the SilcServerCommandContext. Added
332 function silc_server_command_alloc and silc_server_command_dup
335 Same type of functions added to the client library for the same
338 * Removed the cmd_ident from IDListData away since it is now
339 global for all connections. It is the command identifier used
340 in command sending and with pending commands. The affected file
343 * Added reference counter to the SilcSocketConnection objecet to
344 indicate the usage count of the object. The object won't be
345 freed untill the reference counter hits zero. Currently only
346 server uses this, and client ignores it. The client must be
347 set to use this too later. The affected files are
348 lib/silccore/silcsockconn.[ch]. Added also the function
349 silc_socket_dup to increase the reference counter.
351 This was mainly added because it is possible that the socket
352 is removed underneath of pending command or other async
353 operation. Now it won't be free'd and proper DISCONNECTING
354 flags, etc. can be set to avoid sending data to connection that
355 is not valid anymore.
357 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
358 the connection. After that it sets SILC_SET_DISCONNECTED.
359 It is, however, possible that the socket data is not still freed.
360 The silc_server_packet_process now checks that data is not
361 read or written to connection that is DISCONNECTED. The socket
362 get's freed when the reference counter hits zero.
364 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Changed the client operation API: channel_message operation's
367 `sender' is now the client entry of the sender, not the nickname
368 and the `channel' is the channel entry, not the channel name.
370 In the private_message operation the `sender' is now also the
371 client entry of the sender not the nickname.
373 Affected file is lib/silcclient/ops.h and all applications
374 using the client operations.
376 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
378 * Moved the calling of ops->connect() from connect_to_server_final
379 into receive_new_id functin since that is the point when the
380 client is actually allowed to send traffic to network. The
381 affected file is lib/silcclient/client.c.
383 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
386 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
387 (if needs broadcasting) instead of broadcasting the packets one
388 by one which would make a burst in the network traffic.
390 * Added `broadcast' argument to the functions in silcd/server.[ch]
391 silc_server_create_new_channel[_with_id] to indicate whether
392 to send New Channel packet to primary router.
394 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
396 * Added new function into the silcd/server.[ch] files:
397 silc_server_create_new_channel_with_id to create new channel with
398 already existing Channel ID.
400 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
401 lib/silccore/silcpacket.h. This packet is used t send list of
402 Set Mode payloads inside one packet. Server uses this to set
403 the modes for the channels and clients on those channels, that it
404 announced to the router when it connected to it. The protocol
405 specification has been updated accordingly.
407 * The silc_server_new_channel did not handle the packet coming
408 from normal server as it normally does not send that. However,
409 when it announces its channels it does send it. Implemented
410 the support for that.
412 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
413 into the file lib/silccore/id.h.
415 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
417 * Fixed memory leaks in the functions silc_idlist_del_client,
418 silc_idlist_del_channel and silc_idlist_del_server in the file
419 silcd/idlist.c. All of those leaked like a sieve.
421 * Fixed some small memory leaks in the client's function
422 silc_client_notify_by_server.
424 * Added functions into silcd/server.c: silc_server_announce_clients,
425 silc_server_announce_channels and silc_server_announce_server.
426 These functions are used by normal and router server to announce
427 to its primary router about clients, channels and servers (when
428 router) that we own. This is done after we've connected to the
431 These functions effectively implements the following packet types:
432 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
433 and SILC_PACKET_NEW_ID_LIST.
435 * Added new functions into the silcd/packet_receive.[ch]:
436 silc_server_new_id_list, silc_server_new_channel_list and
437 silc_server_new_channel_user_list to handle the incoming
438 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
440 * Added support of changing Channel ID in the function
441 silc_server_replace_id. If the server that announces a channel
442 to the router already exists in the router (with same name but
443 with different Channel ID), router is responsible to send
444 Replace ID packet to the server and force the server to change
445 the Channel ID to the one router has.
447 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
448 client that the Channel ID has been changed by the router. The
449 normal server sends this to the client. Client must start using
450 the new Channel ID as the channel's ID.
452 Implemented handling of this new type into lib/silcclient/client.c
453 into the function silc_client_notify_by_server.
455 * Added new function silc_idlist_replace_channel_id into the files
456 silcd/idlist.[ch] to replace the Channel ID.
458 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
460 * Call silc_server_command_identify_check always when processing
461 the IDENTIFY command in silcd/command.c
463 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
465 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
466 send keepalive packets. The packet can be sent by clients,
469 Added function silc_socket_set_heartbeat into the file
470 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
471 If not set, the heartbeat is not performed. The actual
472 heartbeat is implemented in the low level socket connection
473 library. However, application is responsible of actually
476 Added silc_server_send_heartbeat to send the actual heartbeat
477 packet into silcd/packet_send.[ch]. Server now performs
478 keepalive with all connections.
480 * Added silc_task_get_first function into lib/silcutil/silctask.c
481 to return the timeout task with shortest timeout. There was a bug
482 in task unregistration that caused problems. TODO has been
483 updated to include that task system must be rewritten.
485 * The client library will now resolve the client information when
486 receiving JOIN notify from server for client that we know but
487 have incomplete information.
489 * Rewrote parts of silc_server_remove_from_channels and
490 silc_server_remove_from_one_channel as they did not remove the
491 channel in some circumstances even though they should've.
493 * Encryption problem encountered in server:
495 The LEAVE command used to send the Channel Key packet to the
496 router immediately after generating it. However, the code
497 had earlier sent Remove Channel user packet but not immediately,
498 ie. it was put to queue. The order of packets in the router
499 was that Channel Key packet was first and Remove Channel User
500 packet was second, even though they were encrypted in the
501 reverse order. For this reason, MAC check failed. Now, this
502 is fixed by not sending the Channel Key packet immediately but
503 putting it to queue. However, this is more fundamental problem:
504 packets that are in queue should actually not be encrypted
505 because packets that are sent immediately gets encrypted
506 actually with wrong IV (and thus MAC check fails). So, packets
507 that are in queue should be encrypted when they are sent to
508 the wire and not when they put to the queue.
510 However, the problem is that the current system has not been
511 designed to work that way. Instead, the packet is encrypted
512 as soon as possible and left to the queue. The queue is then
513 just purged into wire. There won't be any fixes for this
514 any time soon. So, the current semantic for packet sending
517 o If you send packet to remote host and do not force the send
518 (the packet will be in queue) then all subsequent packets to the
519 same remote host must also be put to the queue. Only after the
520 queue has been purged is it safe again to force the packet
523 o If you send all packets immediately then it safe to send
524 any of subsequent packets through the queue, however, after
525 the first packet is put to queue then any subsequent packets
526 must also be put to the queue.
528 Follow these rules and everything works fine.
530 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Added new function silc_server_remove_clients_by_server to
533 remove all client entries from ID list when the server connection
534 is lost. In this case it is also important to invalidate all
535 client entires as they hold the invalid server entry. This
536 fixes fatal bug when server has lost connection and will reconnect
539 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Made some sanity checks to silc_server_daemonise like to check
542 whether the requested user and group actually exists.
544 * Added sanity check to SKE's silc_ske_responder_finish to check
545 that the public and private key actually is valid.
547 * Invalidate the client's nickname when receiving Replace ID
548 packet and the Client ID is being replaced. This means that the
549 server will query the nickname if someone needs it (client)
552 * Sort the ID Cache in client library when the ID Cache data
553 has changed (needs sorting).
555 * Do not allow for SILC client to create several connections to
556 several servers. The client does not support windows right now
557 and generating multiple connections causes weird behaviour.
559 Irssi-silc client does support windows and can handle several
560 connections without problems, see: www.irssi.org and SILC plugin.
562 * Fixed some places where client was added to the IDList. The
563 rule of thumb is following (in order to get everything right):
564 If the client is directly connected local client then the
565 `connection' argument must be set and `router' argument must be
566 NULL to silc_idlist_add_client function. If the client is not
567 directly connected client then the `router' argument must
568 bet set and the `connection' argument must be NULL to the
569 silc_idlist_add_client function.
571 * The funtion silc_server_packet_send_local_channel actually did
572 not check whether the client was locally connected or not. It
573 does that now. Fixed a bug related to LEAVE command.
575 * Fixed Remove Channel User payload parsing bug in server's
576 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
578 * The server's silc_server_save_channel_key now checks also the
579 global ID list for the channel as it might not be in the local
580 list. Fixed a bug related to LEAVE command.
582 * Is this the end of the [<unknown>] buglet that has been lurking
583 around for a long time? A little for loop fix in server's
584 silc_server_command_whois_parse that is used by both IDENTIFY
585 and WHOIS command. At least, this was a clear bug and a cause
586 of one type of [<unknown>] buglet.
588 * WHOIS and IDENTIFY commands call the function
589 silc_server_command_[whois/identify]_check function even if
590 we are not router server.
592 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * Added --with-gmp configuration option. If set the GMP
595 is always compiled in the SILC source tree. If not set then
596 it is checked whether the system has the GMP3 installed. If
597 it has then the GMP won't be compiled (the system's headers
598 and library is used), if it doesn't have it then the GMP is
599 compiled in the SILC source tree.
601 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Changed RSA private exponent generation to what PKCS #1
604 suggests. We try to find the smallest possible d by doing
605 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
606 not security fix but optimization.
608 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
610 * Added new config entry [Identity] to fork the server and run
611 it as specific user and group. A patch from Bostik.
613 * Imported Dotconf configuration library into lib/dotconf.
614 This will be used to create the SILC configuration files later.
615 It will appear in the distsribution after this commit.
617 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * A big code auditing weekend happening. Auditing code for
620 obvious mistakes, bugs and errors. Also, removing any code
623 Removed files for being obsolete:
625 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
626 inline in the file lib/silcutil/silcbuffer.h)
628 o lib/silcutil/silcbufutil.c (the header has inline versions)
630 Changed code to fix possible error conditions:
632 o The buffer formatting routines now check that the destination
633 buffer really has enough space to add the data. This applies for
634 both buffer formatting and unformatting
635 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
636 unformatting was changed to accomodate following rules:
637 XXX_*STRING_ALLOC will allocate space for the data into the pointer
638 sent to the function while XXX_*STRING will not allocate or copy
639 the data into the buffer. Instead it sets the pointer from the
640 buffer into the pointer sent as argument (XXX_*STRING used to
641 require that the pointer must be allocated already). This change
642 makes this whole thing a bit more consistent and more optimized
643 (note that the data returned in the unformatting with XXX_*STRING
644 must not be freed now). The routines return now -1 on error.
646 o Tried to find all code that use buffer_format and buffer_unformat
647 and added return value checking to prevent formatting and
648 especially unformatting errors and possible subsequent fatal
651 o Changed ske->x and ske->KEY to mallocated pointers in
652 lib/silcske/silcske.h. Fixed possible data and memory leak.
654 o Added return value checking to all *_parse* functions. Fixed
655 many memory leaks as well.
657 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
658 so that buffer overflows would not happen. All code now also
659 checks the return value as it can fail.
661 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
663 * Added reconnection support to server if the normal server looses
664 its connection to the router (for example if router is rebooted).
665 The server performs normal reconnection strategy implemented
666 to the server. Affected file silcd/server.c.
668 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Added new packet type SILC_PACKET_SET_MODE that is used to
671 distribute the information about changed modes (for clients,
672 channels and clients channel modes) to all routers in the
673 network. Updated the protocol specification accordingly.
675 Added functions into silcd/packet_send.c and
676 silcd/packet_receive.c: silc_server_send_set_mode,
677 silc_server_set_mode.
679 Added new files silcmode.[ch] into lib/silccore that implements
680 the encoding and decoding of Set Mode Payload. Added new type
681 SilcSetModePayload. Moved the definitions of different modes
682 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
684 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * Oops, a little mistake in server's connection authentication
687 protocol. The protocol is not ended with FAILURE but with
688 SUCCESS if the authentication is Ok. :) Affected file is
691 * Implemented NICK_CHANGE notify handling in server in the file
692 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
693 the local clients on the channel. After the changing nickname
694 in router environment snhould work and the [<unknown>] nickname
695 should appear no more.
697 The silc_server_replace_id function that receives the Replace ID
698 payload now sends the NICK_CHANGE notify type also in the file
699 silcd/packet_receive.c
701 * Changed WHOIS and IDENTIFY command to support the maximum amount
702 of arguments defined in protocol specs (3328 arguments). This
703 fixed a bug that caused problems when there were more than three
706 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
708 * Added extra parameter, command identifier, to the
709 silc_client_send_command so that explicit command identifier
712 Changed that ID list routines uses specific command identifier
713 when sending WHOIS/IDENTIFY requests to the server so that they
714 can be identified when the reply comes back.
716 Affected files lib/silcclient/command.[ch],
717 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
719 * Added `sender' argument to silc_server_packet_send_to_channel
720 to indicaet the sender who originally sent the packet to us
721 that we are now re-sending. Ignored if NULL. Affected file
722 silcd/packet_send.[ch].
724 * Added some server statistics support in silcd/server_internal.h
725 SilcServerStatistics structure and around the server code. Also
726 send some nice statistics information when client is connecting
729 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Fixed channel ID decoding in server's JOIN command reply in
732 silcd/command_reply.c
734 * Fixed braodcasting of replace ID payload to not to send it if
735 we are standalone server in silcd/packet_receive.c.
737 * Fixed all channel message sending routines to not to send
738 packets to clients that has router set, since they are routed
739 separately in the same function earlier. Affects file
740 silcd/packet_send.c and all channel packet sending functions.
742 * In USERS reply, res_argv[i] are not allocated, the table
743 is allocated. Thus changed that free the table, not its
746 * In server's whois_check and identify_check if the client is
747 locally connected do not send any WHOIS commands - they are not
750 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
752 * Fixed some minor bugs in client when sending WHOIS command. The
753 arguments was in wrong order.
755 * Removed statis function add_to_channel from server in
756 silcd/command.c that was previously used with the joining but
759 * Tested USERS command in router environment successfully with two
760 routers, two servers and two clients.
762 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Reorganized the USERS command and command reply in client library
765 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
766 When the command is given by user we register a pending command
767 callback that will reprocess the command after the reply has been
768 received from the server. When reprocessing the packet we then
769 display the information. Thus, the USERS information is displayed
770 now in the command callback instead of in the command reply
771 callback. The processing of the command is same as previously
772 when server has sent the command reply in the JOINing process.
774 * Added to USERS command in silcd/command_reply.c to join the client,
775 we didn't use to know about, to the channel after we've created
776 a client entry for it. Also, for clienet we did know already still
777 check whether it is on the channel or not and add it if not.
779 * Removed silc_server_command_join_notify as the function and its
782 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Changed the client's pending command handling to the same as the
785 server's pending command handling. It is also now possible to
786 execute command reply functions from other command reply
787 function as the function callbacks for commands and command
788 replies are one and same. The pending commands are not static
789 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
790 in client connection context. Thus, pending commands are server
791 connection specific as it is convenient.
793 Changed the function silc_client_command_pending and
794 silc_client_command_pending_del and added new function
795 silc_client_command_pending_check. Removed the
796 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
799 * Added cmd_ident, current command identifier, to the client
800 connection context in lib/silcclient/client.h to keep track on
801 command identifiers used in command sending. Client's command reply
802 function handling now supports the mandatory command identifiers.
804 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
805 funtions in client to fully support pending command callbacks.
807 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
808 as one of the arguments to the application in the command reply
811 * NOTE: The FORWARDED flag is depracated. It used to be depracated
812 before first releasing SILC but came back. Now it is removed again
813 and should come back nomore. The FORWARDED flag was used only
814 by the JOINing procedure by forwarding the command packet to router.
815 Now, the JOINing procedure has been changed to more generic (due
816 to various router environment issues) and FORWARDED is not needed
817 anymore for anything. The protocol specification is yet to be
820 Now, removed silc_server_packet_forward from server and the flag
821 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
823 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
825 * Renamed NAMES command to USERS command. The NAMES was named that
826 due to historical reasons. Now it is renamed. Also, rewrote
827 parts of the USERS command. The nickname list is not sent anymore
828 by the server. Only Client ID and mode lists are sent in the USERS
829 command. Changed this also to the protocol specification.
831 The client now resolves the names and stuff after it receives
832 the USERS list from the server when joining to the channel.
834 * WHOIS and IDENTIFY commands has been changed to support multiple
835 Client ID's per command. One can now search for multiple users
836 in the network by sending only one WHOIS or IDENTIFY command.
837 Changed the code and the protocol specifications.
839 * Removed silc_server_command_identify_parse and changed that IDENTIFY
840 uses silc_server_command_whois_parse to parse the request. */
842 * If normal server, do not parse the WHOIS and IDENTIFY requests
843 before sending it to the router. Saves some time.
845 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Fixed JOIN command on client library. Wrong number of arguments
848 used to crash the client.
850 * Added silc_server_channel_has_global function to check whether
851 channel has global users or not.
853 * Added silc_server_channel_has_local function to check whether channel
854 has locally connected clients on the channel.
856 * The silc_server_remove_from_one_channel now checks whether the
857 channel has global users or not after given client was removed from
858 the channel. It also checks whether the channel has local clients
859 on the channel anymore. If it does not have then the channel entry
860 is removed as it is not needed anymore.
862 * The silc_server_notify now checks on JOIN notify whether the joining
863 client is one of locally connected or global. If it is global then
864 the channel has now global users on the channel and that is marked
865 to the channel entry. Also, it now saves the global client to
866 global list who is joining and JOINs it to the channel. This is
867 for normal server, that is.
869 Changed silc_server_send_notify_on_channel,
870 silc_server_packet_relay_to_channel and
871 silc_server_packet_send_to_channel check if we are normal server
872 and client has router set (ie. global client) do not send the
873 message to that client, as it is already routed to our router.
875 * Implemented LEAVE notify type handling in silc_server_notify
878 * Tested LEAVE command in router environment successfully. Tested
879 with two routers, two servers and two clients.
883 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
885 * Implemented SIGNOFF notify type handling in silc_server_notify
888 * silc_server_remove_id now removes the client entry from all channels
889 it has joined and thusly sends SIGNOFF notify type.
891 * Rewrote the NAMES list generation in server by removing two excess
892 loops. The lists are created now inside one loop.
894 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * silc_server_remove_channel_user checks now also global list
897 for channel and client.
899 * silc_server_new_channel_user checks now both local and global
900 list for channel and client. Fixed a bug in client id decoding.
901 Used to decode wrong buffer.
903 * silc_server_channel_message checks now both local and global
904 list for channel entry.
906 * Tested channel joining (hence JOIN) in router environment
907 successfully. Tested with two routers, two servers and two
910 * Tested channel message sending in router environment successfully.
912 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * Added silc_server_save_channel_key into server.[ch] to save the
915 received channel key in Channel Key payload processing. It is
916 also used in JOIN command reply handling.
918 Equivalent function silc_client_save_channel_key added into
919 client.[ch] into client library.
921 * Changed JOIN command reply to send information whether the channel
922 was created or not (is existing already) and the channel key
923 payload. Changed protocol specs accordingly.
925 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
926 the request was sent by ID and not by nickname. Crashed on
929 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
932 now correctly save the received data.
934 * silc_server_free_sock_user_data now notifies routers in the
935 network about entities leaving the network.
937 At the same time implemented functions silc_server_remove_id
938 and silc_server_send_remove_id to receive and send REMOVE_ID
939 packets. The packet is used to notify routers in the network
940 about leaving entities. The ID removed will become invalid in
943 * Added function silc_idlist_del_server into server. Removes and
944 free's server entry from ID list.
946 * silc_server_private_message function now checks, if we are router,
947 that the destination ID really is valid ID, naturally.
949 * In router when NEW_ID packet is received (for new client) the
950 hash of the Client ID is saved in the ID Cache but the
951 client->nickname is set to NULL, instead of putting the hash
954 IDENTIFY command now also checks that client->nickname must be
955 valid. If it is not if will request the data from the server who
956 owns the client. Added new function
957 silc_server_command_identify_check.
959 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
960 to set the command to already allocated Command Payload.
962 * Tested private message sending in router environment with two
963 routers, two servers and two clients. Fixed minor bugs and now
966 * Fixed segfault from client's NAMES command. Used to crash if
969 * Forwarded packets must not be routed even if it is not destined
970 to the receiver. Changed server code comply with this.
972 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Added `require_reverse_mapping' boolean value to ServerParams
975 structure. If TRUE (not default) the server will require that
976 the connecting host has fully qualified domain name.
978 If the reverse mapping is not required and hostname could not be
979 found the IP address is used as hostname.
981 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
983 * Implemented version string checking to both client and server.
984 The check is incomplete currently due to the abnormal version
985 strings used in development version of SILC.
987 * Changed all command functions in server to use the new
990 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
992 * Changed char *data to unsigned char *data in ID Cache system to
993 support binary data as ID Cache data. Changed code to support
994 binary data in lib/silccore/idcache.c.
996 * Renamed silc_server_packet_relay_command_reply to
997 silc_server_command_reply as it is normal packet receiving
998 function. Rewrote the function to accept command replys for
999 servers and not only for clients.
1001 * Mark remote router always as registered server if we are connecting
1002 to it. Otherwise, commands sent by the router to us are ignored.
1004 * All ID List find routines now returns the ID Cache Entry pointer
1005 as well if requested.
1007 * WHOIS command works now in router environment, tested with two
1008 routers, two servers and two clients.
1010 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1011 in router environment (as it is almost equivalent to WHOIS) but
1012 hasn't been tested thoroughly. Added new functions:
1014 silc_server_command_identify_parse
1015 silc_server_command_identify_send_reply
1016 silc_server_command_identify_from_client
1017 silc_server_command_identify_from_server
1019 * Disabled route cache adding because adding two different ID's with
1020 same IP replaces the old cache entry thus giving wrong route.
1021 The entry->router->connection is always the fastest route anyway
1022 so route cache may not be needed. Of course, new routes maybe
1023 established after receiving the ID when the entry->router->connection
1024 might not be anymore the most optimal.
1026 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Add route cache for received ID for fast routing.
1030 * Added silc_server_packet_route to route received packet on router
1031 that is not destined to us.
1033 * Renamed silc_server_get_route to silc_server_route_get.
1035 * Added id_string and id_string_len fields into SilcServer to
1036 include encoded ServerID for fast comparing without excess
1037 encoding of the ID's.
1039 * Cleaned up WHOIS command on server side. Added following static
1042 silc_server_command_whois_parse
1043 silc_server_command_whois_check
1044 silc_server_command_whois_send_reply
1045 silc_server_command_whois_from_client
1046 silc_server_command_whois_from_server
1048 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1049 arguments in command replies. All command functions should be
1050 updated to use this macro.
1052 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Minor typo fixes on command reply handling on server.
1056 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Added silc_server_command_add_to_channel internal routine to add
1059 the client to the channel after router has created the channel and
1060 sent command reply to the server.
1062 * Added generic silc_server_send_command to send any command from
1065 * Use static buffer with ID rendering instead of duplicating data.
1067 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1069 * Fixed a channel user mode bug when joining to a channel server gave
1070 everybody channel founder rights, oops.
1072 * We mark ourselves as the router of the incoming server connection
1073 if we are router ourselves. This way we can check in some packet
1074 sending functions whether it is locally connected server. For
1075 incoming router connections we put NULL.
1077 * For router sending packets locally means now always sending the
1078 packet cell wide; to local clients and local servers. For normal
1079 server sending packet locally means sending it to only local
1082 * Fixed the JOIN command to really work in router environment. If the
1083 channel is created it is always created by the router. Router is
1084 also responsible of making the initial joining to the channel,
1085 sending JOIN notify to the sending server and distributing
1086 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1087 does not exist server doesn't do anything else but forward the
1088 command to the router which performs everything.
1090 * Added silc_server_send_channel_key function to send the Channel Key
1093 * Added silc_server_create_channel_key to create new channel key. The
1094 channel key is now re-generated everytime someone joins or leaves
1095 a channel, as protocol dictates. Note: channel->key_len is the
1098 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1101 packet_receive.[ch] to separate packet sending and receiving
1102 routines. The server.[ch] now includes everything else including
1103 actual packet processing (writing and reading data) and other
1106 Renamed silc_server_private_message_send_internal to
1107 silc_server_send_private_message. The routine is still though
1108 used only to relay private messages as server does not send
1109 private messages itself.
1111 Renamed silc_server_new_channel to silc_server_create_new_channel
1112 and added new function sicl_server_new_channel that handles the
1113 incoming New Channel packet. Added also new sending function
1114 silc_server_send_new_channel to send New Channel Payload.
1116 * Added new function silc_server_notify to process incoming notify
1117 packet to the server/router. Server may then relay the notify
1118 to clients if needed.
1120 * Added new function silc_server_new_channel_user to process incoming
1121 New Channel User packet. Router will redistribute the packet and
1122 send JOIN notify to its local clients and locally connected servers
1123 if needed. Normal server will send JOIN notify to its local client
1124 on same channel when received this packet. Added also corresponding
1125 sending function silc_server_send_new_channel_user to sent the
1128 * Added boolean route argument to send_notif_to_channel and
1129 packet_send_to_channel functions to attempt to route the packet
1130 if it is TRUE and send only locally if it is FALSE.
1132 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1134 * silc_server_replace_id now broadcasts the received replace ID
1135 packet if it is not broadcast packet already. The router must
1136 broadcast to inform other routers about changed ID.
1138 * Added backpointer to server's router into SilcServer context in
1139 silcd/server_internal.h.
1141 * Fixed silc_server_packet_broadcast to send correct broadcast
1144 * The channel key is now distributed to the local client as soon
1145 as it is received from the router (in router environment) so that
1146 no other packet may be sent for the channel until client has
1149 * silc_server_remove_channel_user now broadcasts the received
1150 Remove Channel User packet if it is not broadcast packet already.
1151 The router must broadcast to inform other routers about removed
1154 * Added users field into SilcPacketContext that is a reference count
1155 of the context. One can increase the reference count by calling
1156 silc_packet_context_dup which is now changed to just increase the
1157 reference count instead of duplicating the data. The reference
1158 count is decresed by calling silc_packet_context_free that will
1159 free the data after the reference count hits zero.
1161 For now on the packet context and everything allocated into it
1162 (including the raw packet from network) must be freed by calling
1163 the new silc_packet_context_free function. Added also new function
1164 silc_packet_context_alloc that must be used now to allocate the
1165 context. This also means that if a routine is asynchronous from
1166 silc_[client/server]_packet_parse_type the packet context must
1167 be duplicated by calling silc_packet_context_dup. Otherwise it
1168 gets free'd after silc_[client/server]_packet_parse_type returns.
1169 Also, one must remember that if packet is duplicated then its
1170 reference count must be decresed by calling the free function as
1171 many times as it was duplicated.
1173 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1174 from both client and server.
1176 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Made joining to a channel working in router environment.
1180 * Cleaned up JOIN command on server side and create function
1181 silc_server_command_join_channel internal routine to make the
1184 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * Changed silc_command_pending list to SilcDList. Also, added
1187 `ident' field to SilcServerCommandPending structure to identify
1188 the reply and to call correct callback.
1190 Added silc_server_command_pending_check function to replace the
1191 corresnponding macro. The silc_command_pending list is not
1194 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1195 to set identifier to previously allocated Command Payload. It
1196 is used to set identifier for command when resending Command
1199 * Added silc_command_payload_encode_payload to encode Command
1200 Payload buffer from SilcCommandPayload structure.
1202 * Added silc_argument_payload_encode_payload to encode Argument
1203 payload buffer from SilcArgumentPayload structure.
1205 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Changed WHOIS command to support router connection on server side.
1208 The whois request is always sent to router unless the server is
1209 standalone server. After server has received the reply from the
1210 router will it send the reply to the client.
1212 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1213 broadcast received broadcast packet. The function is used only
1214 by router. The broadcast packet is always sent to the router's
1217 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1218 render given ID to printable string, for log files for example.
1220 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1222 * Made basic router to router connections working. At least they
1223 can now connect to each other but nothing really works the way
1224 they are supposed - yet.
1226 * Added new initiator token to RouterConnection configuration
1227 file in silcd/serverconfig.[ch]. It is used to tell whether we
1228 are the initiator to the remote router or whether we'll expect
1229 the other end to connect.
1231 * Moved registering of listener task to silc_server_init, hence
1232 the server starts listenning as soon as it is run, even if it
1233 does not have connections to other routers. Let's see how well
1236 * Changed default connection retry timeouts for more suitable in
1239 * Removed cipher and such arguments from silc_idlist_add_client
1240 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1241 Added new function silc_idlist_add_data to add the keys and stuff
1244 * Added SilcIDListData structure and added it to SilcClientEntry
1245 and SilcServerEntry as their first field in the structure. This
1246 way we can explicitly cast the ID entries to the SilcIDListData
1247 structure and get common data for the entries. In past, we had
1248 to first check what type of connection it is and then cast it to
1249 correct ID entry type. Now, we can directly cast the opaque
1250 pointer to the SilcIDListData (no matter what ID entry it actually
1251 is) and get the data needed.
1253 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1255 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1256 in some circumstances even if threre were timeout tasks, though not
1257 IO tasks, but tasks anyway. Now fixed.
1259 * Defined SilcServerConnection structure to hold connection specific
1260 stuff about directly connected servers and routers. The definition
1261 is currently in silcd/server_internal.h. I thought about having
1262 a bit more important role fro this struct but for now it is used
1263 only when connecting to other server (or router actually).
1265 * Added connecting retry support in server when connecting to
1266 router(s). The retry feature implement exponential backoff
1267 algorithm. Also, added SilcServerParams structure to hold default
1268 parameters for server. For now, it include these retry settings
1269 and are hard coded. After server is moded to be as Silc Server
1270 Library this structure will be more important.
1272 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Changed client librarys channel->clients table to SilcList and
1275 changed code accordingly.
1277 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1279 * Changed client's channel table to SilcList and changed code
1280 accordingly. Also changed SilcChannelClientEntry to include back-
1281 pointer to the channel so that client entry can use that structure
1282 as list as well and we have fast cross-reference to the channel.
1283 This change dramatically decreased the complexity of channel
1284 handling with client entry and vice versa (removed one extra
1285 loop when searching for channel entry from many functions).
1287 * Changed server->sim from table to SilcDList and changed code
1290 * NAMES command can now be used from user interface. It will show
1291 the user list on the channel, neatly.
1293 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1294 Code now saves realname of the user if it becomes available.
1296 * Renamed configure.in to configure.in.pre and made ./prepare
1297 script to automatically add correct version string to
1298 configure.in which it creates from configure.in.pre.
1300 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * NAMES command reply now shows users mode with the nickname when
1305 * Moved silc_client_ch[u]mode[_char] functions from
1306 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1307 place sucks, they are utility functions and should be in some
1310 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1312 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1315 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Added TRQ (efficient deque and list library) into lib/trq. This is
1320 a very good list library that is currently used in the SILC. Defined
1321 SilcList API over the library because I didn't like the API very
1322 much. See lib/trq/silclist.h for the API and examples of how to
1323 use the API. Fixed various places in the code to use the new
1324 SilcList API. The SilcList is meant for lists that has a structure
1325 already defined as a list. It is not suitable to add just some
1326 context to the list (in TRQ, the context is the list actually).
1328 So, I defined SilcDList that can be used for the purpose where
1329 predefined list structure does not exit. This can be used as
1330 such list. Now some context just can be added to the SilcDList.
1331 Currently this list is not used in the SILC just yet, though there
1332 are a lot places where this can replace dynamically allocated
1333 tables and I will fix these places, later, to use SilcDList.
1334 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1335 and use TRQ internally).
1337 Also fixed some annoying warning messages that the original TRQ
1338 code generated. Also minor changes to TRQ's Makefile.in.
1340 * Added support for querying by Client ID to both WHOIS and
1341 IDENTIFY commands into server, as required by the protocol.
1343 * Removed method function pointers from SilcBuffer structure. They
1344 weren't used to anything and just increased the context size for
1345 no good reason. This change also made silc_buffer_alloc and
1346 silc_buffer_free functions inline functions.
1348 * Disabled command flooding detection support until it's fixed so
1349 that it accepts commands in but does not execute them more than once
1352 * Added silc_net_localhost(), to return local hostname, into
1353 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1354 that must be initialized before calling silc_client_init.
1356 * Added new function: silc_server_send_notify_on_channels to send
1357 notify messages to all channels client has joined. It is assured
1358 that the message is sent only once per client.
1360 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1361 lib/silcutil/silcutil.[ch] as silc_format function. The new
1362 function is generic and is used by server as well, not only by
1363 the logging routines.
1365 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1366 the provided version string was not acceptable. Added new function:
1367 silc_ske_check_version into lib/silcske/silcske.h. The function
1368 must be implemented by the application (client or server) and it
1369 does not reside in the SKE library. The function checks the version
1370 string remote end sent.
1372 * Added back pointers (to opaque context and to SilcSocketConnection)
1373 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1375 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1376 duplicate packet context structure.
1378 * Changed `notify' client operation to send same arguments as client
1379 receives from server except for ID's. ID's are mapped to correct
1380 ID entry and that is returned. Also, if channel entry is not sent
1381 by server but the notify is for channel the channel entry is sent
1382 to application (otherwise application doesn't know that it is for
1383 channel (library gets it from packet's Destination ID)).
1385 * Added silc_client_remove_from_channels into client library to
1386 remove a client from all channels it has joined to. Used when
1387 received SIGNOFF notify from server. Added also new function
1388 silc_client_replace_from_channels to replace old ID entry with
1389 new ID entry on all channels. Used when received NICK_CHANGE
1392 * Fixed ID Cache list handling in silc_idlist_get_client in
1393 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1394 to get (or query) client by ID.
1396 * Updated TODO list.
1398 * Added connection authentication status message defined by the
1399 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1400 support for these into the code in client and server side.
1402 * Added generic function silc_client_send_command to send any command
1403 with variable argument list. Application should use this function
1404 to send commands if the command functions provided by the library
1405 does not suite for the application's user interface needs.
1407 * Added new `failure' client operation. Application is notified about
1408 received failure packet if client is executing a protocol. In this
1409 case the protocol's execution has failed.
1411 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1412 is required by the protocol.
1414 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1415 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1418 * Added status flag to SilcSKE object to indicate realtime status
1419 of the SKE protocol.
1421 * Application receives now exactly same command reply arguments as
1422 the library receives from server. However, if ID is received the
1423 corresponding ID entry is returned to the application (eg. Client
1424 ID is mapped to correct SilcClientEntry entry and that is returned).
1425 Changed command_reply client operation due to this change.
1427 * Changed all ID's in commands and in command replys as ID Payloads.
1428 Change affected both client and server side codes.
1430 All ID's sent in SILC network (with execption of ID's in SILC
1431 Packet header) are sent in ID Payload to support variable length
1434 * Server now notifies nick changes and notifies all clients on
1435 the channels about the new nickname (about the new Client ID,
1438 * Implemented CMODE command to change channel modes. Supports all
1439 channel modes defined by the protocol specs except ban and invite
1440 lists. (Also, private channel key mode is supported but support for
1441 setting private channel key in client is missing, thus, this mode
1442 has no effect on client side (except that server requires that the
1443 client uses private channel key and normal channel traffic does not
1446 Also, invite mode works per se, but INVITE command does not work
1447 yet correctly, so you can set channel as invite only channel but
1448 inviting clients to the channel does not work (it is yet to be
1449 thought what's the best way to do it).
1451 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1452 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1453 Implemented CUMODE command to change user's mode on the channel.
1454 Supports all modes defined by the protocol specs.
1456 * Added NAMES command reply to return users modes on the channel.
1458 * Removed unnecessary and slow ciphers from lib/silccrypt.
1460 * Set SO_KEEPALIVE option to connection sockets by default.
1462 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1464 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1465 redefined the Notify Payload into protocol specs.
1467 * Added silc_id_payload_parse_id to get ID directly from raw
1470 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1473 accept searching by Client ID as well.
1475 * Added support for LEAVE and SIGNOFF notify types in client library.
1477 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1478 to parse ID Payload from raw data.
1480 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Added flags parameter into silc_ske_assemble_security_properties
1483 function in lib/silcske/silcske.[ch].
1485 * Changed notify client operation to fit better for notify messages
1486 sent by server. The notify payload received from server is now
1487 passed to the application (after parsing it to SilcNotifyPayload).
1488 It is application's responsibility to retrieve the arguments
1489 from the payload and show the message the way it wants. The message
1490 sent by server is implementation specific.
1492 * Changed public keys to comply with the protocol specification.
1493 Old public keys are not supported anymore and are not compatible.
1495 * Removed nickname from Channel Payload as the latest draft removed
1496 it. The client must resolve the nickname from the NAMES command
1497 reply received when it joined the channel.
1499 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1501 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1503 * Fixed some errors in protocol specification drafts.
1505 * Created lib/silccore/silcnotify.c to implement Notify Payload
1506 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1507 generic payloads described by protocol specifications. The file
1508 includes implementations for ID Payload and Argument Payload.
1510 * Changed Command Payload implementation to use the new Argument
1511 Payload. Changed command_xxxx_payload to command_payload_xxxx
1512 to comply with SILC coding conventions.
1514 * Added suppport for Argument Payload handling in Notify Payload
1515 implementation as protocol requires it. Added the new support
1516 into server and client lib as well.
1518 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1520 * Added support for multiple nicknames on same channel. [n] is
1521 added locally to the nickname if there are more than one same
1522 nicknames on the channel.
1524 * Server now sends all nicknames that matched WHOIS request.
1525 Client also shows the list received from server.
1527 * Added TOPIC command to client side. User can now set and show
1528 current topic on channel.
1530 * Added MOTD command to client and server. Also, server sends the
1531 motd when client connects to the server.
1533 * Changed version strings to comply ISO 8601.
1535 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Fixed protocol error handling in client library. It should now
1538 cope even if the SKE fails for some reason.
1540 * Made new protocol specification drafts for submitting to IETF.
1542 * Implemented TOPIC command to server in silcd/command.c.
1544 * Added two new notify types into lib/silccore/silcnotify.h:
1545 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1546 notify nickname change and topic setting/change on a channel.
1548 * API change of command_reply operation in client library. The
1549 application gets now the status type received from server as well.
1551 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1555 * Cras fixed and optimized the packet handling even further and
1556 it should work now. Minor change to the prototype of function
1557 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1559 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1561 * Added new function into lib/silcutil/silcschedule.[ch]:
1562 silc_schedule_with_fd to select() a specified fd. The function
1563 returns after timeout expires or data arrives or goes. The
1564 function is used by packet routines to wait that all data is
1565 received from network.
1567 * Fixed data reading from network in lib/silccore/silcpacket.c.
1568 The code now assures that all data is read from the fd and then
1569 continues packet processing. This was a bug fix since the code
1570 used to drop some data in some circumstances.
1572 * Added new function into lib/silcclient/client.[ch]:
1573 silc_client_start_key_exchange to start key exchange after
1574 connection has been established to server. The code internally
1575 now uses this funtion but its main purpose was to provide it
1576 for applications that perform their own connecting. After
1577 application has created a connection it merely calls this
1578 function to start the key exchange between client and server.
1579 The library takes care of everything else after that.
1581 Updated also lib/silcclient/README to explain the usage of
1584 * Do not send to application information that connection has
1585 been established. Application gets notified it by connect
1588 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * Applied cras's patch to add silc_schedule_one function. The
1591 function runs scheduler once and returns.
1593 * Fixed the scheduler after cras messed it up. The timeout
1594 handling works now as it's supposed to work.
1596 * Added into lib/silccore/ silcnotify.h to include notify
1597 message types support. Changed silc_server_send_notify*
1598 functions, in server.[ch], to support those new notify types.
1599 Added the support for the notify types into client library,
1600 as well. Added new notify client operation into ops.h in
1603 * Changed silc_server_packet_send_to_channel to send normal
1604 packets instead of just channel message packets. The function
1605 is now used to send the notify packets to channels. It is not
1606 used to send channel message packets anymore, as server never
1609 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1610 va_arg()s as it seems to require it nowadays. I guess, if SILC
1611 is compiled with older va_arg() the new code should work anyway.
1613 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1615 * Splitted core library. Core library (lib/silccore) includes
1616 now only SILC protocol specific core (and common) components.
1617 Created new utility library (lib/silcutil) that includes more
1618 generic purpose stuff. The stuff for util library was taken
1619 from the old core library. This was minor and easy split.
1621 * Created SILC Client Library (lib/silcclient) that includes
1622 implementation of the SILC client without user interface. This
1623 was major move from silc/ directory. The code has been changed
1624 so that it is transparent towards the user interface. The
1625 silc/ directory includes now the same user interface as before
1626 and it uses the new client library. Read lib/silcclient/README.
1627 Basicly, the client library performs everything else related
1628 to SILC except user interface handling. Also, configuration
1629 files are considered to be part of user interface and library
1630 does not handle them.
1632 This change also changed a lot of structures, function naming etc.
1633 Most important change was that SilcClientWindow object was
1634 renamed to SilcClientConnection in the client library. Created
1635 also new file lib/silcclient/ops.h. Also added new files
1636 silc/local_command.[ch] and silc/client_ops.[ch].
1638 All these changes were made to make it easier for user interface
1639 designers to create what ever user interface for the SILC client
1642 It is also expected that the server will be moved to lib
1643 directory as well and SILC Server Library will be created;
1644 sometimes in the future.
1646 * Removed Local commands from lib/silccore/silccommand.h as
1647 they are application specific and new client library does not
1648 handle any of those anymore.
1650 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1651 old client implementation in silc/.
1653 * Added support for callback functions in SILC_LOG_* macros.
1654 Application can now set its own callbacks that will be called
1655 instead of using the default functions that will always print
1656 the debug messages to stderr (or stdout). Also, debugging can
1657 now be disabled by setting silc_debug to FALSE and re-enabled by
1658 setting it to TRUE. Note, that logging will still work even
1659 if debugging is disabled.
1661 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1662 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1663 silc_log_reset_debug_callbacks.
1665 * To enable debugging in silc client one must give now -d
1666 option on command line.
1668 * Changed silc_schedule_init to automatically allocate task queues
1669 if they are not allocated before calling it.
1671 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Added GMP 3.1 into math library.
1675 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1678 a channel in SILC network. The packet is used by servers and
1679 routers to notify other routers that user has left a channel.
1680 This little feature was missing until now. Added the feature
1681 to protocol specification as well.
1683 Added functions: silc_server_send_remove_channel_user and
1684 silc_server_remove_channel_user into server.[ch].
1686 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1687 lib/silccore/silcpacket.h. However, they are not implemented
1690 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * Fixed joining to a channel and sending channel messages
1693 between server and router. The channel message sending should
1694 now work inside a cell.
1696 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * Fixed the private message sending between server and router.
1699 The private message sending should now work inside a cell.
1701 * Added silc_server_replace_id into server.[ch] to replace
1702 existing ID in the SILC network.
1704 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1705 and silc_idlist_replace_server_id into idlist.[ch] in server.
1707 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * Fixed the server to server connections. Server can again now
1710 connect to router. Router to router connections probably does
1713 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1715 * Added dynamic protocol registering support. Now protocols can
1716 registered and unregistered on the fly. Patch by cras.
1718 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Added lib/contrib directory to hold routines that some platforms
1721 don't have but are needed by SILC.
1723 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1724 into lin/contrib to provide getopt() and getopt_long() for
1725 those who don't have it.
1727 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Added AWAY command to client. When away message is set and
1730 client receives a private message packet the client automatically
1731 replies to the sender with the away message.
1733 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1734 bug seemed to be the cause of recent problems when compiling
1737 * Added version detection support to SKE protocol specification
1738 and added the new changes to the SKE implementation as well.
1739 There were other minor changes in the SKE protocol as well.
1741 Many changes in lib/silcske/silcske.[ch] and in
1742 lib/silcske/payload.[ch].
1744 * Added ^U functionality, clear input line. Patch from cras.
1746 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1748 * Mainly small bugfixes on core library. Fixed some debugging
1749 logging and buffer overflow in silclog.c.
1751 * Updated config.sub and config.guess on the distribution tree.
1753 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1755 * Added command lagging support in server. Client may execute
1756 commands now only once in two seconds.
1758 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Optimized packet reception. MAC computation and checking is now
1761 also more optimized. A lot previously duplicated code is now
1762 used as generic by both client and server.
1764 * Fixed key pair generation in clientutil.c
1766 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1768 * Added into lib/silccore/silcbufutil.[ch] new function;
1769 silc_buffer_realloc.
1771 * Moved generic packet sending/encryption functions to
1772 lib/silccore/silcpacket.[ch] from client and server. Some
1773 rewriting of the functions.
1775 * Moved all generic packet reception/decryption functions to
1776 lib/silccore/silcpacket.[ch] from client and server. The
1777 packet processing is now much cleaner in both client and server.
1778 These were major changes in both client and server.
1780 * Created many common functions in server to do packet sending.
1781 Previously code were duplicated a lot, this has been removed
1784 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Rewrote major parts of the ID cache system. Don't know
1787 whether it is better now or not but at least the API is more
1790 * Major rewrite on ID cache stuff on client because of the ID
1791 cache API changes. Added idlist.c to client.
1793 * Also major rewrite on ID cache stuff on server as well.
1794 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1795 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1796 in hand, instead they are all put into the ID cache system now.
1797 All server_idlist_* routines uses ID cache now instead of
1798 traversing its own lists (those lists does not exist anymore).
1799 SilcIDList though still exists. Also, SilcXXXEntry's are
1802 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1804 * Finally made the SKE implementation compliant to the protocol
1805 specification. All mp integers are now binary encoded as
1806 opposed being HEX encoded.
1808 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1811 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1812 functions: silc_[encode/decode]_pem. Also added function
1813 silc_encode_pem_file to PEM encode with newlines ('\n') for
1816 * SILC public keys are now encoded either PEM or binary. Same
1817 option is for private keys as well. By default private keys
1818 are binary encoded and public keys PEM encoded. Silly HEX
1819 encoding were removed.
1821 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
1822 function to create fingerprints.
1824 * Fixed a bug in SHA1; does not change the original data anymore.
1826 * Partly implemented INFO command on client and server side.
1827 Fixed CLEAR command. Changes to SERVER command; show current
1828 server(s) when giving command without arguments. Added
1829 VERSION command to client.
1831 * Added check to server that unregistered connections cannot
1832 execute commands (unless it is specificly allowed).
1834 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Fixed screen refresh.
1838 * Fixed channel joining bug from client. On some circumstances
1839 client tried to join to a channel it had already joined.
1841 * Added public key verification process into client's protocol.c.
1842 The client now verifies the public key from user and saves
1843 it into ~./silc/serverkeys/ directory.
1845 Added into: clientutil.[ch]: silc_client_verify_server_key.
1847 * Changed SKE protocol's silc_ske_initiator_finish function
1848 to accept callback function that verifies the received public
1849 key. Removed old silc_ske_verify_public_key function.
1851 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1853 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
1854 silc_pkcs_private_key[_data]_set.
1856 * Made the password and public authentication more cleaner in
1857 server's protocol.c.
1859 * Removed historic and obsolete protocol `channel_auth' from
1860 both client and server.
1862 * Removed wrong way of sending command status messages from
1863 server to client in server's command.c. The old way violated
1864 protocol specification.
1866 Changes to silccore/silccommand.[ch]: removed
1867 silc_command_encode_status_payload -> not needed anymore,
1868 changed silc_command_encode_payload_va to accept extra
1869 argument on variable argument list. The argument type must
1870 now be provided to the function. Also, added new function:
1871 silc_command_encode_reply_payload_va which is same as
1872 normal command_encode_payload_va except command status type
1873 is provided as extra argument.
1875 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Added ~./silc directory handling. The directory includes the
1878 public and private keys for the client.
1880 Added silc_client_check_silc_dir, silc_client_create_identifier
1881 and silc_client_load_keys.
1883 * Implemented SILC protocol compliant public key. Added public
1884 and private key saving to and loading from files.
1886 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
1887 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
1888 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
1889 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
1890 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
1892 Implemented: silc_pkcs_save_[public/private]_key[_data] and
1893 silc_pkcs_load_[public/private]_key.
1895 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * Added silc_server_get_route (route.[ch]) to get connection
1898 data for the fastest route for given ID.
1900 * Implemented INVITE command on client and server. The command
1901 were re-defined in the SILC Protocol Specification and the
1902 implementation now complies with the specification.
1904 * Implemented PING command on client and server.
1906 * Implemented NAMES command on client and server. The server side
1907 supports currently only normal server not router server yet.
1908 Some changes to NAMES definition in SILC protocol specification.
1910 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Implemented LEAVE command on client and server.
1914 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
1915 again. This change was made to the protocol as well. Server
1916 should not violate the protocol specification anymore.
1918 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
1921 was tested. SOCKS4 was not but should work anyway.
