3 * Use cache entry expire time in the LIST command reply to
4 purge old entries from the cache after the LIST command
5 reply has been received. This way we don't have non-existent
6 entries in the cache for too long. Affected file is
9 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
11 * If we are normal server, and we've not resolved client info
12 in WHOIS or IDENTIFY from router, and it is global client,
13 we'll check whether it is on some channel. If it is not
14 then we cannot be sure about its validity and will resolve it
15 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
18 * Search channel by name (if possible) rather than by ID
19 in IDENTIFY command's command reply. Affected file is
20 silcd/command_reply.c.
22 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
24 * Distribute to the channel passphrase in CMODE_CHANGE notify.
25 Updated specs and implemented it. Affected file silcd/command.c,
26 silcd/packet_send.c and silcd/packet_receive.c.
28 * Implemented the <founder auth> payload handling in the JOIN
29 command. If provided all conditions for channel joining
30 except requirement to provide correct passphrase can be
31 overrided by the channel founder. Updated the protocol specs.
32 Affected file silcd/command.c.
34 Added support for founder auth in JOIN command in client
35 library. Fixed the parsing of the JOIN command now to support
36 all options as they should be. The affected file is
37 lib/silcclient/command.c.
39 * Optimized the WHOIS and IDENTIFY commands to send the request
40 to router only if it includes nicknames or other names. If
41 they include only IDs then check the local cache first before
42 routing. Affected file is silcd/command.c.
44 * Added channels topic announcements. Affected file is
45 silcd/packet_receive.c and silcd/server.c.
47 * Fixed the silc_server_send_notify_topic_set to really destine
48 the packet to channel. Affected file silcd/packet_send.c.
50 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
51 library. Affected file lib/silcclient/client_notify.c.
53 * Added UMODE announcements. Affected file silcd/server.c.
55 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
57 * Memory leak fixes in:
59 lib/silcutil/silcsockconn.c
63 lib/silccrypt/silcpkcs.c
64 lib/silccore/silccommand.c
65 lib/silccore/silcidcache.c
70 * ROBOdoc documented the lib/silcske/groups.h file and a
71 bit changed the interface for better.
73 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
75 * Update the client entry context in the ID cache after
76 nick change. Affected file lib/silcclient/command.c.
77 Fixes the CUMODE command when regaining founder privileges,
78 and a little WHOIS problem.
80 * Fixed silc_net_gethostbyname to correctly call the
81 inet_ntop. Affected file lib/silcutil/silcnet.c.
83 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
85 * Added IPv6 support checking to the configure.in.pre, added
86 also --enable-ipv6 option to override the check. Affected
87 file configure.in.pre.
89 * The silc_thread_create now calls the start function
90 directly if threads support is not compiled in. Removes
91 ugly #ifdef's from generic code. Affected files are
92 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
94 * Added silc_net_gethostby[name/addr]_async to asynchronously

106 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
107 routines. Added silc_net_is_ip[4/6]. Affected file is
108 lib/silcutil/unix/silcunixnet.c. All routines that take
109 address as argument now supports both IPv4 and IPv6 addresses.
111 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
113 * Fixed LIST command reply sending in server. Affected file
116 * Server now sends the kicker's client ID in the KICK notify
117 to the kicked client. Affected file silcd/command.c.
119 * The client library now parses the kickers client ID and
120 UI displays it. Affected files lib/silcclient/client_notify.c
121 and irssi/src/silc/core/silc-channels.c, module-formats.c.
123 * Made all payload parsing function prototypes consistent.
124 They all take now const unsigned char * and uint32 pair as
125 the payload data instead of SilcBuffer. Changes all around
126 the source tree. Other unsigned char* -> const unsigned char*
127 changes around the tree as well.
129 * Optimized SFTP client and server packet sending not to
130 allocate new buffer for each packet but to recycle the
131 first allocated buffer. Affected files are
132 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
134 * Optimized the SFTP client to use SilcList instead of
135 SilcDList for requests, because it is faster. Affected file
136 is lib/silcsftp/sftp_client.c.
138 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
139 into lib/silccore/silcid.[ch].
141 Renamed silcpayload.[ch] into silcargument.[ch].
143 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
145 * If client entry is deleted with active key agreement
146 session, abort the session.
148 The silc_client_abort_key_agreement now calls the completion
149 callback with new SILC_KEY_AGREEMENT_ABORTED status.
151 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
154 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
156 * Don't use __restrict in older GCC's. Affected file is
157 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
159 * silc_net_localhost now attempts to reverse lookup the
160 IP/hostname. Affected file lib/silcutil/silcnet.c.
162 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
163 command. It can be used to gain founder privileges at
164 the same time when joining the channel.
166 Defined that the SILC_NOTIFY_TYPE_KICKED send the
167 kicker's client ID as well. Updated protocol specs.
169 Defined that the server must send SILC_COMMAND_IDENTIFY
170 command reply with error status to client who sent
171 private message with invalid client ID.
173 Updated the protocol specification.
175 * Added silc_server_send_command_reply to send any
176 command reply. Affected file silcd/packet_send.[ch].
178 * Added silc_id_payload_encode_data to encode ID payload
179 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
181 * The server now send IDENTIFY command reply with error
182 status if client ID in private message is invalid. Affected
183 file silcd/packet_receive.c.
185 * Save the server key file with server's IP address in
186 the filename instead of hostname. The affected file is
187 irssi/src/silc/core/client_ops.c.
189 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
191 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
194 * Added libtool support for compiling shared objects in
195 lib/silcsim. Affected file configure.in.pre and
196 lib/silcsim/Makefile.am. Original patch by cras.
198 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
200 * Pid file configuration, and server's config file fixes
201 patch by toma. Updated CREDITS file.
203 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
205 * Fixed silc_client_channel_message to not try to decrypt
206 the message twice if it resolved the destination client
207 information. This could cause of dropping one channel
208 message. Affected file lib/silcclient/client_channel.c.
210 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
212 * Added silc_client_run_one into lib/silcclient/silcapi.h and
213 lib/silcclient/client.c. This function is used when the SILC
214 Client is run under some other scheduler, or event loop or
215 main loop. On GUI applications, for example this may be
216 desired to used to run the client under the GUI application's
217 main loop. Typically the GUI application would register an
218 idle task that calls this function multiple times in a second
219 to quickly process the SILC specific data.
221 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
223 * Fixed silc_server_drop() for dropping the supplementary
224 groups as well, this could cause a security hole on some
227 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
229 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

233 to run server on foreground. A patch by debolaz.
234 Affected files silcd/server.c, silcd/silcd.c.
236 * Fixed MOTD to return the MOTD file server name. Affected
237 file silcd/command.c.
239 * Added INFO command reply handling to the Irssi SILC Client.
240 Affected file irssi/src/silc/core/client_ops.c.
242 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
244 * Fixed the silc_idcache_list_* routines to really support
245 the dynamic list. Fixes a crash. Affected file is
246 lib/silccore/silcidcache.c.
248 * Fixed the LIST command reply to really call LIST command's
249 pending callbacks. Affected file silcd/command_reply.c.
251 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
253 * Update conn->local_entry->nickname after giving NICK
254 command. Affected file lib/silcclient/command.c.
256 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
258 * Added the [pid] option to the silcd configuration file
260 Affected files: serverconfig.[ch] and silcd.c
262 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
264 * Save fingerprint in WHOIS command reply in server.
265 Affected file silcd/command_reply.c.
267 * Fixed NICK commands pending callback registration.
268 Affected file lib/silcclient/command.c.
270 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
272 * Use ++server->cmd_ident when sending commands in server,
273 instead of random number. Affected file silcd/command.c.
275 * Fixed GETKEY command reply to call actually GETKEY pending
276 command callbacks. Affected file silcd/command_reply.c.
278 * A bit stricter check for nicknames. Check for same nickname
279 in NICK command also. Affected file silcd/command.c.
281 * Do not call INFO command everytime client ID changes, only
282 during first connecting. Affected file lib/silcclient/client.c.
284 * Set the new nickname only after successful command reply for
285 NICK command is returned by server. Affected file
286 lib/silcclient/command.c.
288 * Remove nicknames from nicklist during server_signoff notify.
289 Should fix /NAMES bit more. The affected file is
290 irssi/src/silc/core/silc-channels.c.
292 * Added `fingerprint' field to the SilcIDListData in the
293 silcd/idlist.h to hold the fingerprint of the client's
296 Send the fingerprint of the client's public key in WHOIS
299 Affected files silcd/command.c, and silcd/idlist.[ch].
301 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
302 create fingerprint from given data.
304 * Show the fingerprint of the client's public key in WHOIS.
305 Affected files irssi/src/module-formats.[ch] and
306 irssi/src/silc/core/client_ops.c.
308 * Format the multiple same nicknames also during JOIN and
309 NICK_CHANGE notifys. Affected file is
310 lib/silcclient/client_notify.c.
312 * Do not print error on screen for invalid private message
313 payload since it can come if someone is sending private
314 messages with wrong key. Affected file
315 lib/silccore/silcprivate.c.
317 * Fixed multiple concurrent /PING crash. Affected file
318 lib/silcclient/command.c.
320 * Changed the wrong ID encoding. All IP addresses must be
321 in MSB first order in encoded format. They were encoded
322 wrong and was in LSB format. Affected files are
323 silcd/serverid.c, lib/silcutil/silcutil.c.
325 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
327 * Call the `connect' client operation through the scheduler
328 in case of error. Affected file lib/silcclient/client.c.
330 * Call the `failure' client operation even if the error
331 occurred locally during a protocol. Affected file is
332 lib/silcclient/protocol.c.
334 * Added support of sending LIST command to router from normal
335 server. This way normal server can get list of all channels
336 in the network too. Fixed the channel list sending in the
337 server too. Affected files are silcd/command.c, and
338 silcd/command_reply.[ch].
340 * Added silc_server_update_channels_by_server and
341 silc_server_remove_channels_by_server. They are used during
342 disconnection of primary router and in backup router protocol.
343 Affected file silcd/server_util.[ch], silcd/server.c and
344 silcd/server_backup.c.
346 * Fixed channel adding to global list in IDENTIFY command
347 reply in server. Affected file silcd/command_reply.c.
349 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
351 * If the incoming packet type is REKEY or REKEY_DONE process
352 that packet always synchronously. Fixes yet another MAC
353 failed error on slow (dialup) connections. Affected file
354 lib/silcclient/client.c and silcd/server.c.
356 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Call check_version SKE callback for initiator too. Affected
359 file lib/silcske/silcske.c.
361 * Implemented fix for security hole found in the SKE that was
362 fixed in the specification few days back; the initiator's
363 public key is now added to the HASH value computation.
364 Added backwards support for the old way of doing it too, for
365 old clients and old servers. Affected file is
366 lib/silcske/silcske.c.
368 * Enabled mutual authentication by default in SKE. If initiator
369 is not providing mutual authentication the responder will
370 force it. This will provide the proof of posession of the
371 private key for responder. The affected files are
372 lib/silcclient/protocol.c and silcd/protocol.c.
374 * Do not cache anymore the server's public key during SKE.
375 We do mutual authentication so the proof of posession of
376 private key is done, and if the server is authenticated in
377 conn auth protocol with public key we must have the public
378 key already. Affected file silcd/protocol.c.
380 * Added new global debug variable: silc_debug_hexdump. If
381 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
382 file lib/silcutil/silclog.[ch].
384 * Fixed compilation warning due to char * -> const char *.
385 Affected files lib/silcutil/silcnet.h, and
386 lib/silccore/silcauth.[ch].
388 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
390 * Fixed CMODE command when new channel key was created. If
391 the creation failed the old key was removed. Next time giving
392 same command would crash the server since the old key was
393 freed already. Affected file silcd/command.c.
395 * Fixed the silc_server_announce_get_channels to not crash
396 on reconnect. Affected file silcd/server.c.
398 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
400 * Added silc_log_set_debug_string function to set a regex
401 string to match for debug output. Only the function names,
402 or filenames matching the given debug string is actually
403 printed. This way it is possible to filter out those debug
404 strings that user is not interested in.
406 Fixed a bug in silc_string_regexify.
408 Affected files lib/silcutil/silclog.[ch], and
409 lib/silcutil/unix/silcunixutil.c.
411 * Changed the -d options in both server and Irssi SILC client
412 to take the debug string as argument. Affected files
413 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
415 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
417 * Added silc_hash_babbleprint to create a Bubble Babble
418 Encoded fingerprint. The encoding is developed by Antti
419 Huima (draft-huima-babble-01.txt), and it creates human
420 readable strings out of binary data. Affected file
421 lib/silccrypt/silchash.[ch].
423 * Print the babble print now in addition of fingerprint as well
424 in Irssi SILC client. Affected files are
425 irssi/src/fe-common/silc/module-formats.[ch],
426 irssi/src/fe-common/silc/core/client_ops.c.
428 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
430 * Fixed a security problem found in SKE. The initiator's
431 public key too is now added to the HASH hash value creation
432 which is signed by the responder to create the SIGN value.
433 This will prevent anyone in the middle to lie to the responder
434 about the initiator's public key. If this is done now, the
435 man in the middle will get caught. Updated the protocol
438 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Better installation directory handling. Configure module
441 paths and other paths automatically to example_silc* files
442 in doc/. A patch by toma.
444 * Fixed compiler warning from MPI library, and from SILC RNG.
447 * Added SILC_SERVER_PID_FILE to define the pid file for server.
448 It can be configured with ./configure. A patch by toma.
450 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Find correct make to use in prepare-clean. A patch by
453 toma. Affected file prepare-clean.
455 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
457 * Added irssi variables use_auto_addr, auto_bind_ip,
458 auto_bind_port and auto_public_ip.
460 * Changed the interface for silc_client_send_key_agreement
461 in lib/silcclient/silcapi.h
465 irssi/src/silc/core/silc-core.c
467 lib/silcclient/silcapi.h
468 irssi/src/silc/core/silc-channels.c
469 lib/silcclient/client_keyagr.c
472 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
474 * Added silc_pkcs_public_key_compare to compare two
475 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
477 * Check that the client who set the founder mode on the
478 channel is the same client that is giving the founder
479 mode to itself. It is done by comparing the saved public
480 key (it is saved even in the authentication is passphrase).
481 Affected file silcd/command.c.
483 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
485 * Do not process packet for disconnected socket connection.
486 Affected file lib/silccore/silcpacket.c.
488 * Process the DISCONNECT packet through scheduler in the
489 client library. Affected file lib/silcclient/client.c.
491 * Fixed the silc_client_packet_parse to not to increase
492 the packet sequence number if the conn->sock and the
493 current socket connection is not same. This can happen
494 for example during key agreement when the conn includes
495 multiple socket connections (listeners). Affected file
496 lib/silcclient/client.c.
498 * The sender of the file transfer request now provides also
499 the pointer (listener) for the key exchange protocol. If
500 the listener cannot be created then it sends empty key
501 agreement and lets the receiver provide the listener.
503 Added `local_ip' and `local_port' arguments to the
504 silc_client_file_send. If they are provided they are used,
505 if not then it will attempt to find local IP address, if
506 not found or bind fails then the remote client will provide
509 Affected files are lib/silcclient/client_ftp.c and
510 lib/silcclient/silcapi.h.
512 * Extended the FILE SEND command to support defining the
513 local IP and port for key exchange listener. They are
514 optional. Affected file irssi/src/silc/core/silc-servers.c.
516 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
518 * Defined to WHOIS command reply the sending of fingerprint
519 of the client's public key (if the proof of posession of the
520 corresponding private key is verified by the server).
521 Updated to the protocol specification.
523 * Added support of receiving the client's public key's
524 fingerprint in command reply in client library. Affected
525 file is lib/silcclient/command_reply.c, and
526 lib/silcclient/idlist.[ch].
528 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
530 * Do not send over 128 chars long nickname to the server
531 in NICK command. Affected file lib/silcclient/command.c.
533 * Do not send over 256 chars long channel names to the server
534 in JOIN command. Affected file lib/silcclient/command.c.
536 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
538 * Assure that silc_server_close_connection cannot be called
539 twice for same socket context. Affected file is
542 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Send error message to application if opening file for
545 writing during file transfer fails. Affected file is
546 lib/silcclient/client_ftp.c.
548 Remove all file transfer sessions for a client that we're
549 removing from ID cache.
551 Affected file is lib/silcclient/client_ftp.c.
553 * Fixed silc_net_addr2bin to return correct address. Affected
554 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
556 * Fixed file transfer session removing on signoff notify.
557 Affected file irssi/src/silc/core/silc-servers.c.
559 * Added the SilcClientFileError to be returned in the monitor
560 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
561 Affected file lib/silcclient/silcapi.h.
563 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Fixed a crash in silc_client_ftp_free_sessions and
566 silc_client_ftp_session_free_client. Affected file
567 lib/silcclient/client_ftp.c.
569 * Added `disabled' field in the SilcChannelEntry in the server
570 to indicate if the server entry is disabled. Affected file
571 silcd/idlist.h, silcd/command[_reply].c.
573 * SILC server adds now /var/run/silcd.pid everytime it is
574 started. Affected file silcd/silcd.c.

581 client library. Affected file lib/silcclient/client_prvmsg.c.
583 * Do not actually remove the client directly from ID cache
584 during SERVER_SIGNOFF, but invalidate it. This way we
585 preserve the WHOWAS info for the client. Affected file
588 * Fixed SERVER_SIGNOFF notify handling in the server. The
589 server is now able to process incoming SERVER_SIGNOFF notify
590 for a server that it doesn't even know about. It will remove
591 the clients provided in the notify. Affected file
592 silcd/packet_receive.c.
594 * Check for partial packet in data queue after every packet that
595 was found from the queue. Return and wait for more data if
596 there is partial data in queue. Affected file is

607 * Check that newsize in silc_buffer_realloc is larger than
608 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
610 * Added better monitor of file transfers. It now monitors
611 key agreement protocol during the file transfer too. Added
612 error reporting too. Affected files
613 irssi/src/silc/core/silc-servers.c,
614 irssi/src/fe-common/silc/module-formats.[ch].
616 * Wrote a help file for FILE command.
618 * Added silc_rng_global_get_byte_fast to get not-so-secure
619 random data as fast as possible. Random data is read from
620 /dev/urandom if available and from the SILC RNG if not
621 available. It is used in padding generation. Affected file
622 lib/silccrypt/silcrng.[ch].
624 * All packets in client library are now processed synchronously.
625 Optimized packet processing a lot. Affected file
626 lib/silcclient/client.c.
628 * All server connection packets are processing synchronously
629 now in server, to optimize packet processing. Affected file
632 * Include files are installed now only in Toolkit distribution
633 if make install is given. Affected files: all Makefile.am's.
635 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Assure that silc_client_notify_by_server_resolve does not
638 resolve the client information multiple times. If it cannot
639 be found by the first it cannot be found at all. Affected
640 file lib/silcclient/client_notify.c.
642 * Fixed WHOWAS command reply calling. Affected file
643 lib/silcclient/command_reply.c.
645 * Removed all references to silc_idlist_get_client from the
646 Irssi SILC client since that call is internal call used by
647 the library. The Irssi SILC client will use now client
648 retrieval functions found in silcapi.h.
650 * Fixed a bug in resolving nickname info before sending
651 private message. It used freed memory. Affected file
652 irssi/src/silc/core/silc-servers.c.
654 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

673 * Added silc_net_localip to return local host's IP address.
674 Affected file lib/silcutil/silcnet.[ch].
676 * If key exchange or rekey protocol is active for a connection
677 parse all packets syncronously since there might be packets
678 in packet queue that we are not able to process without first
679 processing packets before them. Affected file silcd/server,
680 lib/silcclient/client.c.
682 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
683 whether library should continue processing the packet.
684 Affected file lib/silccore/silcpacket.h.

715 lib/silcutil/silcutil.[ch].
717 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
719 * Resolve the client info when received private message or
720 channel message for a client which nickname we don't know.
721 Affected files lib/silcclient/client_prvmsg.c and
722 lib/silcclient/client_channel.c.
724 * Do not crash in /KEY if client is not connected. Affected
725 file irssi/src/silc/core/silc-channels.c.
727 * Added SilcClientStatus field to the SilcClientEntry in the
728 lib/silcclient/idlist.h.
730 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
731 is incomplete and is being resolved, it won't be resolved
734 Make sure also that USERS command reply does not resolve
735 twice information. Affected file is
736 lib/silcclient/command_reply.c.
738 Make sure that silc_client_get_clients_by_list does not
739 resolve twice same information.
741 * Check for valid client->id in the silc_server_free_client_data.
742 Affected file silcd/server.c.
744 * Fixed /GETKEY nick@server not to crash if the server entry
745 is not found. Affected file lib/silcclient/command.c.

753 Affected file silcd/command.c.
755 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Call the silc_server_udpate_servers_by_server in the
758 primary router that comes back online in the backup resuming
759 protocol. Otherwise it routes packets wrong. Affected file
760 silcd/server_util.[ch], silcd/server_backup.c.
762 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
764 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
765 lib/silcutil/silcbuffmt.[ch].
767 * Redefined the SILC packet header to include the padding
768 length. Affected file lib/silccore/silcpacket.[ch].
770 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
771 length for maximum padding up to 128 bytes). Affected
772 file lib/silccore/silcpacket.h.
774 * Removed all backwards support for old 0.5.x MAC thingies.
775 The SILC packet header change makes it impossible to be
776 backwards compatible.
778 * Send the ENDING packet with timeout in the backup resuming
779 protocol. This is to assure that all routers has connected
780 to the primary router. Affected file silcd/server_backup.c.
782 * Changed the RNG to take the first IV from random data. It
783 used to take it from zero actually. Changed the RNG also
784 to use /dev/urandom during session. /dev/random is used
785 in initialization. Affected file lib/silccrypt/silcrng.[ch].
787 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
789 * Changed the SILC packet header to have the first two bytes
790 (the packet length) encrypted. Affected files aroung the
791 code tree, lib/silccore/silcpacket.[ch]. Removed the
792 SilcPacketCheckDecrypt callback. It is not needed anymore
793 since the silc_packet_receive_process will determine now
794 whether the packet is normal or special.
796 * Implemented the unidirectional MAC keys. Affected files
797 lib/silcske/silcske.c, silcd/protocol.c and
798 lib/silcclient/protocol.c.
800 * Implemented the packet sequence number to the MAC computation.
801 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
802 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
803 lib/silcclient/protocol.c.
805 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Allow backup router to announce servers. All servers
808 announced by backup router are added to the global list
809 automatically. Update hte server's socket to our primary
810 router also when backup router announces a server.
811 Affected file silcd/packet_receive.c.
813 * Do not update the client->router in the function
814 silc_server_udpate_clients_by_server if the client is on
815 global list. We might fail to find any specific server
816 for locally connected clients and local cell clients. They
817 should still use the `from' and not `to' as client->router.
818 This fixes backup router resuming protocol. Affected file
821 * Decrease channel statistics count only if the channel
822 deletion worked. Affected files are silcd/server.c and
825 * Added silc_server_update_servers_by_server to update origin
826 of all server entries. Used during backup router protocol.
827 Affected files silcd/server_util.[ch], silcd/server.c. and
828 silcd/backup_router.c.
830 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
831 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
832 silc_hmac_get_hash and silc_hmac_get_name. Affected file
833 lib/silccrypt/silchmac.c.
835 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
837 * Assure that router cannot reroute the same channel message
838 to the sender. Affected file silcd/packet_receive.c.
840 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
842 * Made better checks that the channel message is not sent
843 to the router it came from. Affected file is
844 silcd/packet_send.c. Fixed memory leak too.
846 * Announce informations for incoming router connection, but
847 only after checking if it is replaced by backup router.
848 Affected file silcd/packet_receive.c.
850 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
852 * Fixed the backup resuming protocol to work in multiple
853 router environment. Affected file silcd/server_backup.c.
855 * Route packet only to one router in the function
856 silc_server_packet_send_to_channel. Affected file is
859 * Fixed silc_server_send_notify_dest to set the broadcast
860 flag. Fixed the silc_server_send_notify_topic to actually
861 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
862 Affected file silcd/packet_send.c.
864 * Changed the SFTP Filesystem interface. Changed the
865 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
866 the filesystem operation function. The SilcSFTPFilesystem
867 is now a context that is allocated by all filesystem allocation
868 functions and it already includes the operations structure
869 and filesystem specific context. It is given as argument
870 now to the silc_sftp_server_start. This made the interface
871 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
872 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
874 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
876 * Changed the backup router adding and getting interfaces
877 in the server. The router that will be replaced by the
878 specified backup router is now sent as argument. Affected
879 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
882 * Added silc_net_addr2bin_ne to return the binary form of
883 the IP address in network byte order. Affected files
884 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
886 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Check for existing server ID in silc_server_new_server
889 and in silc_server_connect_to_router_final and remove the
890 old entry if it exists. Affected file silcd/packet_receive.c,

930 * Assure that if outgoing data buffer is pending do not force
931 send any data. Affected file lib/silcclient/client.c.
933 * Implemented the backup router support when the primary router
934 goes down. The servers and routers can now use the backup
935 router as new primary router without loosing connectivity.
937 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
940 in the server to indicate disabled entry. All data read
941 from the connection will be ignored and no data is sent
942 for entry that is disabled. Affected files are
943 silcd/idlist.h, silcd/server.c.
945 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
947 * Created SFTP client and server test programs in the
948 lib/silcsftp/tests directory.
950 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Implemented memory filesystem (virtual filesystem) for
953 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
956 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Implemented the SFTP (SSH File Transfer Protocol) to the
959 lib/silcsftp. It includes SFTP client and SFTP server
962 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Moved lib/silccore/silcprotocol.[ch] to the
965 lib/silcutil library.
967 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
968 take variable argument list pointer as argument. Affected
969 file lib/silcutil/silcbuffmt.[ch].
971 * Added silc_buffer_set function that is used to set data
972 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
973 Affected file lib/silcutil/silcbuffer.h.
975 * Changed various routines in the core library to use the new
976 silc_buffer_set instead of allocating new buffer only for
979 * Added 64-bit value formatting and unformatting support to the
980 silc_buffer_[un]format routines. Affected file is
981 lib/silcutil/silcbuffmt.[ch].
983 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
984 to includes/bitmove.h.
986 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Fixed channel user mode saving in client library. Affected
989 file lib/silcclient/command[_reply].c.
991 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Defined the file transfer to the SILC Protocol. Added
994 new packet type SILC_PACKET_FTP and defined File Transfer
995 Payload. The mandatory file transfer protocol is SFTP
996 (SSH File Transfer Protocol). Affected file in addition
997 of the internet draft is lib/silccore/silcpacket.h.
999 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1000 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1001 is used as part of backup router protocol when the primary
1002 router of the cell is back online and wishes to resume
1003 the position as primary router.
1005 * Redefined the MAC generation keys in the protocol. The
1006 same key is not used anymore in both direction. Both
1007 direction will now use different keys for sending and
1008 receiving. This fixes a potential security flaw. This
1009 change causes incompatibilities in the protocol.
1011 * Redefined also the MAC computation from the packet.
1012 An packet sequence number is now added to the MAC
1013 computation. This prevents possible replay attacks against
1014 the protocol. This change too causes incompatibilities
1017 Added `sequence' field to the SilcPacketContext to hold
1018 the current sequence number for the packet.
1020 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Added `created' field to the SilcIDListData in the file
1023 silcd/idlist.h to indicate the time when the entry was
1026 * Added `created' field to the SilcChannelEntry too. Affected
1027 file silcd/idlist.h.
1029 * Added `creation_time' aguments to all the announcement functions
1030 in the server. If it is provided then only the entries that
1031 was created after the provided time frame are actually
1032 announced. Affected file silcd/server.[ch].
1034 * The protocol says that the Channel ID's IP address must be
1035 based on the router's IP address. Added check for this in
1036 the silc_server_new_channel when processing incoming New Channel
1037 Payload. Affected file silcd/packet_receive.c.
1039 * Print out the correct version with --version in SILC client.
1040 Affected file irssi/src/silc/core/silc-core.c.

1045 entry always, not just when the command is coming from client.
1046 Affected file silcd/command.c.
1048 * Added new function silc_server_packet_queue_purge to purge the
1049 outgoing data queue to the network. After the function returns
1050 it is guaranteed that the outgoing packet queue is empty.
1051 Affected file silcd/packet_send.[ch].
1053 * Purge the outgoing packet queue in the rekey protocol's final
1054 callback to assure that all rekey packets go to the network
1055 before quitting the protocol. Affected file silcd/server.c.
1057 * Added silc_client_packet_queue_parse as similar function as
1058 in server to the client library. The affected file is
1059 lib/silcclient/client.c.
1061 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * Splitted silcd/server.c and created silcd/server_util.[ch]
1064 for utility functions.
1066 * Added new socket flag SILC_SF_DISABLED to indicate that the
1067 connection is open but nothing can be sent to or received from
1068 the connection. Affected file lib/silcutil/silsockconn.[ch].
1069 The checking for disabled socket is checked in the low level
1070 silc_socket_write and silc_socket_read functions.
1072 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Allow only nicknames and channel names that fits into the
1075 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1077 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * When processing JOIN command reply in server check that if
1080 the channel exists in our global list we'll move it the local
1081 list. Affected file silcd/command_reply.c.
1083 * Fixed the check whether client is joined on the channel already
1084 in JOIN command. Affected file lib/silcclient/command.c.
1086 * Fixed the JOIN command reply to check whether the channel
1087 already exists. Affected file lib/silcclient/command_reply.c.
1089 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1091 * Added silc_ske_status_string to map the SKE error numbers
1092 to readable strings. The affected files are
1093 lib/silcske/silcske[_status].[ch].
1095 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1097 * Do not show the private channels on the WHOIS channel list
1098 as it is not allowed by the protocol. The affected file is
1101 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Assure that the packet length digged from the actual packet
1104 is something sensible in the silc_packet_decrypt_rest_special
1105 in lib/silccrypt/silcpacket.c.
1107 * Free and NULL the allocated pointer in silc_hmac_alloc if
1108 the HMAC allocation fails. The affected file is
1109 lib/silccrypt/silchmac.c.
1111 * Print the selected security properties to the log files in
1112 the server. Affected file silcd/protocol.c.
1114 * Add SKE's reference counter even if calling the completion
1115 callback manually. Otherwise it goes negative, although it
1116 does not cause any problems. The affected file is
1117 lib/silcske/silcske.c.
1119 * Remove the client entry with short timeout after giving the
1120 KILL command. Affected file lib/silcclient/command.c.
1122 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1123 case all found clients are already disconnected (WHOWAS would
1124 found them) in the server. Affected file silcd/command.c.
1126 * Update the last_receive (time of last data received) to be
1127 updated only when received private or channel message so that
1128 the idle time showed in WHOIS makes more sense.
1130 * Added boolean field `valid' in to the SilcClientEntry in the
1131 client library to indicate whether the entry is valid or not.
1132 This fixes the nickname change bug on channel when changing
1133 the nickname to be same than the old (like nick to Nick) the
1134 nickname formatter doesn't set the new nick anymore to Nick@host.
1135 Affected file lib/silcclient/idlist.[ch].
1137 * Now actually fixed the nickname changing on disconnection.
1138 Added new function silc_change_nick to the Irssi SILC Client.
1139 Affected file irssi/src/silc/core/client_ops.c,
1140 irssi/src/silc/core/silc-nicklist.[ch].
1142 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1144 * Check that the public key exists in the GETKEY command before
1145 trying to encode it. Affected file silcd/command.c.
1147 * Print some notifications on received public keys with GETKEY
1148 command in the Irssi SILC Client. Affected files are
1149 irssi/src/fe-common/silc/module-formats.[ch],
1150 irssi/src/silc/core/client_ops.c.
1152 * Use IDENTIFY command to resolve the server information in the
1153 GETKEY command instead of INFO command. Affected file
1154 lib/silcclient/command.c.
1156 * All command reply functions in the client library now calls
1157 the pending command reply callbacks even if an error has
1158 occurred. The server has done this a long time and now it was
1159 time to move the client library to this as well. Now all
1160 errors can be delivered back to the pending command reply
1161 callbacks if necessary. Affected files are
1162 lib/silcclient/command[_reply].[ch].
1164 * Change the nickname on disconnection back to the username
1165 because in reconnect the server will enforce it to it anyway.
1166 Affected file irssi/src/silc/core/silc-servers.c.
1168 * Fixed a config file parsing bug in the Irssi SILC client.
1169 Affected file irssi/src/silc/core/clientconfig.c.
1171 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1173 * When printing the channel mode on JOIN, verify that the
1174 channel key and channel's HMAC are valid. Affected file
1175 irssi/src/silc/core/client_ops.c.
1177 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1180 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1181 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1183 * Removed channel key rekey task deleting from the function
1184 silc_server_save_channel_key. Affected file silcd/server.c.
1185 Added explicit timeout task context instead that is used to
1186 delete the task if we are registering a new task before the
1187 new task has elapsed.
1189 * When channel key rekey occurs the client library now saves
1190 the old channel key for a short period of time (10 seconds) and
1191 is able to use it in case some is still sending channel
1192 messages encrypted with the old key after the rekey. Affected
1193 file lib/silcclient/[idlist.h|client_channel.c].
1195 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Added check to the silc_server_new_id_real to not accept
1198 new ID if it is the sender's own ID. Affected file is
1199 silcd/packet_receive.c.
1201 * Assure that we do not announce ourself or the one we've
1202 sending our announcements when we're router and are announcing
1203 servers to our primary router. Affected file silcd/server.c.
1205 * Fixed silc_server_command_identify_check_client to assemble
1206 correct WHOIS packet. It send corrupted WHOIS packet and
1207 caused problem with router to router connections. Affected
1208 file silcd/command.c.
1210 Fixed also silc_server_command_whois_check the same way
1211 as for the IDENTIFY command.
1213 * Added new SilcIDListStatus to the server in the SilcIDListData
1214 structure. The status now includes the current status of
1215 the entry (like registered, resolved etc.). Affected file
1216 silcd/idlist.[ch]. Defined a bunch of different status types
1217 as well. This replaced the old boolean registered field as well.
1219 Added resolve_cmd_ident field to the SilcClientEntry structure
1220 too so that if the entry is for example being resolved so
1221 another command may attach to the same pending command reply
1222 without requiring to resolve the same entry again. This concept
1223 should optimize the WHOIS and the IDENTIFY resolving under
1224 heavy load by taking away unnecessary resolving for entries
1225 that are being resolved already.
1227 Added support for adding multiple pending commands for one
1228 command idenfier. Affected file silcd/command[_reply].[ch].
1230 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1231 before deleting the data. Otherwise the hash table will have
1232 freed data in comparison functions. Affected file is
1233 silcd/command_reply.c.
1235 * Fixed silc_idlist_replace_client_id to add the new entry to
1236 the cache with NULL nickname. Otherwise there will be invalid
1237 memory as the nickname after the nickname is freed. Affected
1238 file silcd/packet_receive.c.
1240 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1241 saved into wrong slots because the previous number of entries
1242 was not taken into account. Affected file silcd/idlist.c.
1243 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1245 * If we are router and we receive JOIN notify to a channel that
1246 does not have any users then notified client is marked as the
1247 channel founder, as it is it. The affected file is
1248 silcd/packet_receive.c
1250 * Added to the extended hash table API's table_del_*ext functions
1251 the destructor as argument too, so that the caller can decide
1252 which destructor to use or whether to use destructor at all.
1253 Affected file lib/silcutil/silchashtable.[ch].
1255 * Fixed ID Cache purging. It actually deleted the entries from
1256 the hash table after the data was freed. The hash table ended
1257 up comparing freed memory. The affected file is
1258 lib/silccore/silcidcache.c.
1260 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1262 * Fixed Irssi SILC client's KILL command's HELP syntax.
1264 * The USERS command now resolves the detailed user information
1265 if the userinfo field is missing. Affected file is
1266 lib/silcclient/command_reply.c.
1268 * Do not print error in silc_file_read if the read file does
1269 not exist. Just silently return NULL. Affected file is
1270 lib/silcutil/silcutil.c.
1272 * Fixed the silc_log_output to not wine about NULL filename
1273 and to not create some bogus " " filename. Affected file is
1274 lib/silcutil/silclog.c.
1276 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Fixed various printing bugs on the user interface in the
1279 Irssi SILC Client. Minor changes that were forgotten from
1282 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1284 * Fixed the configure.in.pre and the compilation and distribution
1285 environment to support the new autoconf 2.52. That version is
1286 now required to compile the CVS trunk.
1288 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1291 to generally parse user@fqdn format strings. Affected file
1292 lib/silcutil/silcutil.c.
1294 * Added nickname_format and nickname_force_format fields to the
1295 SilcClientParams structure. The first one defines the format
1296 for the nicknames that the library will enforce if the receives
1297 multiple same nicknames. The second one is boolean value and
1298 can be used to force the library to always enforce the format
1299 to the nicknames regardles whether there are multiple nicknames
1300 or not. This configurable formatting was employed to flexibly
1301 support accessing multiple nicknames from the user interface.
1302 The userinterface can now set the nicknames to what ever format
1303 they prefer. Affected file lib/silcclient/silcapi.h.
1305 Added function silc_client_nickname_format to the file
1306 lib/silcclient/idlist.c. It performs the nickname formatting.
1308 Added new field `hostname´ to the SilcClientEntry context.
1309 It holds the hostname of the client. Affected file is
1310 lib/silcclient/idlist.h.
1312 * Irssi SILC Client sets the nicknames in nick@hostn format.
1313 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1314 irssi/src/silc/core/silc-core.c.
1316 The WHOIS printing now also shows both the real nickname and
1317 the formatted nickname so that user knows how to access the
1318 user if there are multiple same nicknames cached. Affected
1319 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1320 printing formatting too to take the hostname now as a separate
1321 argument. The Affected file is
1322 irssi/src/fe-common/silc/modules-formats.[ch].
1324 * Changed the silc_client_get_clients_local to accept the formatted
1325 nickname as argument. It accepts the real nickname too but the
1326 formatted nickname can be used to find the true entry from
1327 multiple entries. Affected file lib/silcclient/silcapi.h and
1328 lib/silcclient/idlist.c.
1330 * Added nickname_format_parse field to the SilcClientParams.
1331 It is a callback function provided by the application to parse
1332 the nickname out of the formatted nickname string. The library
1333 calls it to get the nickname from the formatted string. Since
1334 the application generally knows better the format of the nickname
1335 string it parses it instead of the library, even though library
1336 encodes the formatted string. If the callback function is not
1337 provided then the library will use the string as is. The
1338 affected file is lib/silcclient/silcapi.h.
1340 * All the nickname strings passed to the client library in
1341 commands are now expected to be formatted nickname strings.
1342 If the command does not support the formatted nickname string
1343 it will assume that the sent string is the actual nickname.
1344 Affected file lib/silcclient/command.c.
1346 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1348 * Added public key authentication support to OPER and SILCOPER
1349 commands in the client library. Affected file is
1350 lib/silcclient/command.c.
1352 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Changed the get_auth_methdod client operation to be asynchronous.
1355 It can be async if the application resolves the authentication
1356 method from the server during the negotiation. Added new
1357 SilcGetAuthMeth completion callback that the application will
1358 call after resolving the authentication method.
1360 Added function silc_client_request_authentication_method that
1361 the application can use to resolve the authentication method
1362 from the server. Added also SilcConnectionAuthRequest callback
1363 that the library will call after the server has replied. The
1364 application can call this function if it does not know the
1365 current authentication method.
1367 Affected files are lib/silcclient/client.c and
1368 lib/silcclient/silcapi.h.
1370 * The Irssi SILC client now automatically resolves the authentication
1371 method incase any configuration information is not present (and
1372 currently there never is). The affected file is
1373 irssi/src/silc/core/client_ops.c.
1375 * Fixed public key authentication from the client library.
1376 Affected file lib/silcclient/protocol.c. Changed also the
1377 protocol specification about the public key authentication in
1378 the connection authentication protocol. The actual data to be
1379 signed is now computed with a hash function before signing.
1381 * Fixed the public key authentication from the server as well.
1382 Affected file silcd/protocol.c.
1384 * Removed the mlock()'s from the memory allocation routines.
1385 Affected file lib/silcutil/silcmemory.c. The ./configure does
1386 not check anymore for the mlock(). Affected file is
1389 * Fixed USERS command in server to allow the execution of the
1390 command for private and secret channels if the client sending
1391 the command is on the channel. Affected file silcd/command.c.
1393 * Fixed silc_client_get_clients_local to return the clients
1394 count correctly. It could return wrong value. Affected file
1395 lib/silcclient/idlist.c.
1397 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1400 types. The assembler optimizations seemed not to like 64-bit
1401 data types. The assmebler optimizations thus are now enabled
1402 also for BSD systems as opposed to only enable them for Linux.
1404 * Do not check for threads at all on BSD systems. Affected
1405 file configure.in.pre.
1407 * Removed -n and -h options from the Irssi SILC Client since
1408 they are not used in silc.
1410 * Fixed the prime generation to assure that the first digit
1411 of the generated random number is not zero since our conversion
1412 routines does not like number strings that starts with zero
1413 digit. If zero digit is seen the random number is regenerated.
1414 This caused some corrupted RSA keys when the zero first digit
1415 was met. Affected file lib/silcmath/silcprimegen.c.
1417 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Fixed WIN32 configuration in the ./configure script.
1420 Fixed to include xti.h on environments that has it.
1421 Patches by Carsten Ilchmann and andrew.
1423 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Changed the silc_id_create_client_id to be collision
1426 resistant. It is now assured that there cannot be created
1427 two same client ID's. I suspect that some weird bugs in
1428 the server were actually caused by duplicate Client IDs.
1429 Affected file silcd/serverid.[ch]. A router receiving
1430 new ID now also assures and informs the sending server
1431 if the ID caused collision.
1433 * Changed the silc_id_create_channel_id to also assure that
1434 there are no collisions.
1436 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Statement about ignoring the Mutual Authentication flag when
1439 performing rekey with PFS was a bit misleading. It is ignored
1440 if it was set in the initial negotiation, it cannot be even
1441 set in the rekey. Fixed in the ke-auth draft. Started the
1442 new versions of the protocol drafts in the doc/.
1444 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Fixed a bug in silc_client_command_identify_save when saving
1447 new channel information. The channel name was no duplicated
1448 and caused crash on exit. Affected file is
1449 lib/silcclient/command_reply.c.
1451 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Fixed the getkey command handling in the server. Send just
1454 empty OK reply to the sender if the key could not be fetched
1455 (but everything else was ok, like the key just was not available).
1456 Changed the public key parameter to optional in the protocol
1457 specs so that empty OK reply can be sent. Affected file
1460 Added a message to Irssi SILC client to tell to user if the
1461 server did not return a public key.
1463 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Fixed a channel key regeneration bug. It registered new
1466 timeout tasks exponentially until all system resources were
1467 used. Affected file silcd/server.c.
1469 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * Added the SILC Document generator to the scripts/silcdoc.
1472 It can be used to generate the Toolkit Reference Manual out
1473 of the source tree. Internally it will also use the RoboDoc
1474 generator now imported in util/robodoc.
1476 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Added couple of return's in rekey protocol if error orccurred
1479 during the protocol. The execution must be terminated.
1480 Affected file silcd/protocol.c. Also, terminate the protocol
1481 always with timeout.
1483 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1485 * The client's Client ID was created initally from the wrong
1486 nickname (it could have been in format nick@host) in the
1487 silc_server_new_client. Affected file silcd/packet_receive.c
1489 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Added some SILC_LOG_ERROR's to various error conditions
1492 if client could not be added to ID cache. Affected files
1493 silcd/packet_receive.c and silcd/server.c.
1495 * When client's sock->user_data is freed, NULL also the
1496 client->router and client->connection pointers. Added check
1497 for these pointers being NULL to various places around the
1498 code. Affected file silcd/server.c.
1500 * Added client->data.registered == TRUE checks to various
1501 places around the code to assure that unregistered client's
1502 are not handled when it is not allowed. Affected file
1505 * Added `bool registered' fields to all
1506 silc_idlist_[server|client]_get_* routines to indicate whether
1507 the fetched client needs to be registered or not. Affected
1508 file silcd/idlist.[ch].
1510 * Add your own entry as registered to the ID cache in the
1511 server. Affected file server.c.
1513 * Fixed a bug in silc_server_new_server. The SilcServer was
1514 set as the new server's context instead of SilcServerEntry.
1515 This naturally caused some weird bugs.
1517 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Do not delete the channel rekey task when adding it
1520 for in silc_server_create_channel_key.
1522 * Changed the silc_server_create_channel_key to return
1523 TRUE or FALSE to indicate the success of the channel key
1526 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Fixed MSVC++ project files and added missing files to
1529 Makefiles under win32/.
1531 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Do not add TCP_NODELAY flag if the operating system
1534 does not have it defined. Affected files are
1535 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1537 * Fixed buffer overflow from Irssi SILC Client. Affected
1538 file irssi/src/fe-common/core/themes.c.
1540 * Fixed double free in client library in the file
1541 lib/silcclient/client.c when disconnecting from server.
1543 * Applied double free patch from cras to Irssi SILC client.
1544 Affected files irssi/src/core/[modules/expandos].c
1546 * Fixed the disconnection handling to Irssi SILC Client.
1547 The application must call silc_client_close_connection
1548 in ops->connect client operation in case of failure of
1549 the connection. Affected file is
1550 irssi/src/silc/core/client_ops.c.
1552 * Do not set sock->protocol to NULL in the function
1553 silc_client_close_connection after executing the protocol's
1554 final callback since the sock might not be valid anymore.
1555 Affected file lib/silcclient/client.c.
1557 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Do not enable SILC_THREADS if the linking with libpthread
1560 did not happen. Affected file configure.in.pre.
1562 * Added notion to protocol specification that server must
1563 verify the sent authentication payload with CMODE when
1564 setting the channel founder key. Implemented it to the
1565 server. Affected file silcd/command.c.
1567 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Added _EXTRA_DIST SILC distribution variable to the
1570 distributions file. It is used to conditionally add extra
1571 files or directories to the specific distribution. Affected
1572 files ./prepare, Makefile.am.pre and distributions.
1574 Removed the `_' from the start of the distribution names.
1577 * Added README.WIN32 for instructions to compile the Toolkit
1580 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Fixed a double free in disconnection in the server. Affected
1583 file is silcd/server.c.
1585 * Fixed the lib/silcske/groups.c to work now also with GMP
1586 MP library. The string conversion did not work when using
1587 specific base and the base is indicated in the string as well.
1589 * Created win32/ directory which now includes MSVC++ specific
1590 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1591 It will appear only in the toolkit distribution
1593 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Changed the key material distribution function in case when
1596 the hash output is too short. The data is now concatenated
1597 a bit differently than it used to. Made the change to the
1598 SKE protocol specification.
1600 * Added better GMP detection to configure.in.pre. A patch
1603 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * Fixed a minor bug in SKE that might cause some problem on
1606 some platforms. Affected file lib/silcske/silcske.c.
1608 * Added the cookie checking for initiator in the SKE. It checks
1609 that the responder returns the sent cookie unmodified. The
1610 affected file is lib/silcske/silcske.c. Added new SKE
1611 error type INVALID_COOKIE that can be sent during the
1612 negotiation. Fixed some memory leaks as well.
1614 * Added the "invalid cookie" error message to Irssi SILC client's
1617 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Added `task_max' field to the SilcClientParams to indicate
1620 the maximum tasks the scheduler can handle. If set to zero,
1621 default values are used. Affected file lib/silcclient/silcapi.h.
1623 * Fixed memory leaks in silc_client_close_connection. Affected
1624 file lib/silcclient/client.c.
1626 * Added silc_client_del_client_entry to client library to free
1627 all memory of given client entry. Affected file is
1628 lib/silcclient/idlist.[ch].
1630 * Added new functions silc_client_del_channel and
1631 silc_client_del_server to delete channel and server entries.
1632 Affected file lib/silcclient/[silcapi.h/idlist.c].
1634 * Removed silc_client_del_client_by_id from silcapi.h.
1636 * Fixed the INFO command to return the server's own info
1637 correctly when querying by Server ID. Affected file is
1640 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Removed the non-blocking settings in WIN32 code in the
1643 silc_sock_[read/write] and added SleepEx instead. Affected
1644 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1645 of input data is now checked with FIONREAD and ioctlsocket.
1647 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Call silc_schedule_task_del_by_context in the
1650 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1651 Affected file lib/silccore/silcprotocol.c.
1653 * Call silc_protocol_cancel for active protocols in the
1654 silc_server_close_connection if the funtion
1655 silc_server_free_sock_user_data has not been called.
1656 Affected file silcd/server.c.
1658 * Generic tasks cannot be deleted using the del_by_fd
1659 task deleting function since generic tasks does not match
1660 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1662 * Added a notion to SILCOPER help file that the SILCOPER works
1663 only on router server, not on normal server.
1665 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added for WIN32 support for the new scheduler as well.
1668 Affected file lib/silcutil/win32/silcwin32schedule.c.
1670 * Fixed the SHA1 implementation to work on various platforms.
1672 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1675 API. It is part of the scheduler now. Everything else is
1676 as previously but some functions has changed their names.
1677 Checkout the lib/silcutil/silcschedule.h for the interface.
1678 Updated all applications to use the new interface. Affected
1679 files are lib/silcutil/silcschedule.[ch].
1681 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Found a bug in the SKE implementation. The HASH value,
1684 specified by the protocol, was not computed correctly. The
1685 public key of the responder was not added to the computation
1686 even though it is mandatory. Affected file lib/silcske/silcske.c.
1687 This unfortunately causes incompatibilities with older
1688 clients and servers.
1690 * Added WIN32 specific network init and uninit functions:
1691 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1692 the Winsock2. Affected file lib/silcutil/silcnet.h and
1693 lib/silcutil/win32/silcwin32net.c.
1695 * Set the socket always to nonblocking mode on WIN32 after
1696 reading data or writing data. Affected file is
1697 lib/silcutil/win32/silcwin32sockconn.c.
1699 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1701 * Fixed various compilation problems under WIN32. Affected
1702 files lib/silcutil/win32/silcwin32thread.c and
1703 lib/silcutil/win32/silcwin32schedule.c.
1705 * Removed all _internal.h #includes from public header
1706 files. Internal headers must never be included from
1709 Removed also the lib/silcske/payload_internal.h file.
1711 * All include files that may be needed (public and some others
1712 included by the public headers) by application developers are
1713 now copied to the ./includes directory. It does not copy any
1714 internal headers. Affected file Makefile.defines.pre and all
1715 Makefile.am's under lib/ and subdirs.
1717 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Do not change the ~/.silc directory's permissions automatically.
1720 Affected file irssi/src/silc/core/clientutil.c.
1722 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Do not cancel the protocol in silc_server_close_connection
1725 it might cause recursion. Now cancelled in the function
1726 silc_server_free_sock_user_data. Affected file silcd/server.c.
1728 * Fixed the silc_server_remove_clients_by_server to regenerate
1729 the channel keys correctly finally. Added also new function
1730 silc_server_remove_clients_channels to actually do it.
1731 Affected file silcd/server.c.
1733 * Fixed the silc_server_new_channel to not crash by giving
1734 wrong router to the new channel. Affected file is
1735 silcd/packet_receive.c.
1737 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1739 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1740 which is given as argument to the silc_client_alloc now.
1741 It can be used to configure the client and set various parameters
1742 that affect the function of the client.
1744 * The USERS command in server did not check whether the channel
1745 is private or secret. Affected file silcd/command.c.
1747 * Added new argument to the USERS command in protocol specification.
1748 The USERS command now can take the channel name as argument
1749 as well. Added support for this in client and server and
1750 updated the protocol specs.
1752 * Completed the GETKEY command in client. It can be now used
1753 to fetch also servers public key not only some clients.
1754 Affected files lib/silcclient/command[_reply].c.
1756 * Added silc_client_get_server to return server entry by the
1757 server name. Affected files lib/silcclient/silcapi.h and
1760 * Redefined the IDENTIFY command in protocol specification to be
1761 more generic. It now can be used to query information about
1762 any entity in the SILC Network, including clients, servers and
1763 channels. The query may be based either the entity's name
1764 or the ID. Added support for this in both client and server.
1766 Affected files silcd/command.c and lib/silcclient/command.c
1767 and command_reply.c.
1769 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1770 the _from_client and _from_server functions. Affected file
1773 * Added silc_client_get_channel_by_id_resolve to the file
1774 lib/silcclient/silcapi.h to resolve channel information by
1775 its ID. Added also silc_client_get_channel_by_id that
1776 does not resolve it from the server.
1778 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Added SilcServerEntry context into the client library
1781 to represent one server. The INFO command now allocates
1782 these to save the resolved server info. For now on the
1783 client library will also keep information about servers,
1784 connected and resolved with INFO.
1786 The INFO command now allocates the SilcServerEntry context
1787 and saves the server info there. The COMMAND_REPLY in
1788 the INFO now returns the parameters to application in
1789 same order as defined in the protocol specification.
1791 The entries are cached in the client->server_cache.
1793 * The INFO command is now issued after received the Client ID
1794 from the server. Affected file lib/silcclient/client.c.
1796 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1797 to the application as the mode changer might be server.
1798 It is guaranteed that NULL is not returned anymore to the
1799 application. Affected file lib/silcclient/client_notify.c.
1801 The ID Type is now also passed to the application so that
1802 it can check whether the returned entry is SilcClientEntry
1805 Added new function silc_client_get_server_by_id to return
1806 the server entry by ID. Affected files are the
1807 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1809 * Do not create the channel in the Irssi SILC Client when issuing
1810 the JOIN command but when received the sucessful JOIN command
1811 reply. Otherwise the channel might get created even though we
1812 could not join it. The Affected file is
1813 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1815 * Fixed a channel joining bug in router. The router must also
1816 check the channel modes, invite and ban lists etc. when serving
1817 the JOIN command sent by normal server. Affected file is
1818 silcd/command.c. The router now resolves the client's
1819 information from the server who sent the JOIN command if it
1820 does not know it, and processes the JOIN command only after
1823 * Changed the SilcCommandCb to take new argument; void *context2.
1824 Affected file lib/silccore/silccommand.h
1826 The second argument in the command callbacks in the server now
1827 includes the SilcServerCommandReplyContext if the command was
1828 called as pending command callback from the command reply.
1829 Otherwise it is NULL. When called as pending the status of the
1830 command reply will be checked and if it was erronous the
1831 error will be sent to the original sender of the command.
1832 This way the client always receives the error messages even
1833 though the server was actually the one who received the error
1834 when it resent the command to router, for example. Affected
1835 files silcd/command[_reply].[ch].
1837 * Fixed sending WHOWAS command's error message to client if
1838 the requested client could not be found. It was missing.
1841 * Changed the CMODE and CUMODE commands reply arguments in the
1842 protocol specification. The Channel ID is now sent in both
1843 of the commands to identify the channel. Implemented this
1844 new feature to the client and server. Affected files
1845 lib/silcclient/command_reply.c and silcd/command.c.
1847 * Made better checks for invite and ban lists in the JOIN
1848 command in server. Affected file silcd/command.c.
1850 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * The server now performs the incoming host IP/DNS lookup
1853 using the silc_socket_host_lookup and thus does not block
1854 the server anymore. Affected file silcd/server.c.
1856 * Completed the multi-thread support for SILC Scheduler in
1857 the lib/silcutil/silcschedule.c.
1859 * Fixed the configure.in.pre to detect the pthread correctly
1862 * Fixed a deadlock in silc_task_queue_wakeup in the file
1863 lib/silcutil/silctask.c.
1865 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * Added new function silc_schedule_wakeup that is used in
1868 multi-threaded environment to wakeup the main thread's
1869 schduler. It needs to be used when a thread adds a new task
1870 or removes a task from task queues. After waking up, the
1871 scheduler will detect the task queue changes. If threads
1872 support is not compiled in this function has no effect.
1873 Implemented the wakeup mechanism to both Unix and WIN32
1874 systems. Affected files are lib/silcutil/silcschedule.[ch],
1875 lib/silcutil/unix/silcunixschedule.c and the
1876 lib/silcutil/win32/silcwin32schedule.c.
1878 * Added new function silc_task_queue_wakeup to wakeup the
1879 scheduler by the specified task queue. Affected file
1880 lib/silcutil/silctask.[ch].
1882 * The silc_socket_host_lookup_start now wakes up the scheduler
1883 after adding the timeout task. Affected file is
1884 lib/silcutil/silcsockconn.c.
1886 * The silc_socket_host_lookup is synchronous now if the threads
1887 support is not compiled in. However, the callback is still
1888 called asyncronously through the scheduler, anyway. Affected
1889 file lib/silcutil/silcsockconn.c.
1891 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Added new function silc_socket_host_lookup to perform
1894 asynchronous IP and FQDN lookups for the socket connection.
1895 Affected files lib/silcutil/silcsockconn.[ch].
1897 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1900 that may or may not compile the mutex support in.
1902 Changed the silc_mutex_alloc interface. It allocates the
1903 mutex now to the sent pointer and returns TRUE or FALSE.
1905 Affected file lib/silcutil/silcmutex.h.
1907 * Wrote the SILC Task Queue interface to support multi-threads.
1908 Affected file lib/silcutil/silctask.[ch].
1910 * Wrote the SILC Scheduler to support multi-threads. Affected
1911 file lib/silcutil/silcschedule.c.
1913 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1916 in lib/silcutil/win32/.
1918 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Defined SILC Mutex API and SILC Thread API and implemented
1921 them for Unix. Affected files are
1922 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1923 lib/silcutil/unix/silcunixmutex.c and
1924 lib/silcutil/unix/silcunixthread.c.
1926 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Fixed the silc_server_remove_clients_by_server's channel
1929 key re-generation. The hash table handling was incorrect
1930 and would not work with many channels. Affected file is
1933 * Fixed some memory leaks around the server code.
1935 * Rewrote the silc_server_get_users_on_channel to support IPv6
1936 based Client ID's. Affected file silcd/server.c.
1938 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1939 specification. However, a separate document must be written
1940 to define the detailed signing procedure and the payload
1941 associated with the flag. Defined the flag to the
1942 lib/silccore/silcchannel.h as well.
1944 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Changed the dynamic tables to static size tables in the
1947 lib/silccrypt/silchmac.c.
1949 * Removed GCC dependencies from the code. A patch by cras.
1951 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Do not show the error "Error receiving packet bla bla"
1954 in server if it really was not an error (-2 means that reading
1955 is pending). Affected file silcd/server.c.
1957 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Fixed a possible crash in silc_server_remove_clients_by_server
1960 in silcd/server.c. Fixed there also some memory leaks.
1962 * Fixed the silc_idlist_replace_client_id. It could replace
1963 wrong key in the hash table. Affected file silcd/idlist.c.
1965 * Do not check whether there are global users on the channel
1966 if the channel->global_users is FALSE. Affected functions
1967 silc_server_remove_from_one_channel and
1968 silc_server_remove_from_channels in silcd/server.c. Also,
1969 do not check if the removed client is local as we can be
1970 sure that global client was not removed from the channel
1971 and checking for global users is not needed.
1973 * The silc_server_remove_clients_by_server now re-generates
1974 the channel keys correctly for those channels that had
1975 clients removed from them. Affected file silcd/server.c.
1977 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Found the reason of random crashes in the server. We weren't
1980 ignoring the SIGPIPE signal (which can be sent in write())
1981 and it crashed the server. Affected file silcd/silcd.c.
1983 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Assure that sock->user_data is not NULL in the function
1986 silc_server_packet_send in silcd/packet_send.c.
1988 * Disconnect the remote connection if it could not be added
1989 to any ID lists in the server. The affected file is
1992 * Check in silc_server_packet_send[_real/dest] that the
1993 socket is not disconnecting and ignore the data if it is.
1994 Affected file silcd/packet_send.c.
1996 * Define inline to __inline on native WIN32 compilation.
1997 Affected file includes/silcwin32.h.
1999 * Added some explicit type casts for inline code since MSVC
2000 require them. Affected files lib/silcutil/silcbuffer.h,
2001 lib/trq/silcdlist.h and lib/trq/silclist.h.
2003 * Print warning in log files from now on if the packet
2004 decryption fails. Affected file silcd/server.c.
2006 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * Changed the `say' client operation's interface to accept
2009 new `type' argument to indicate the type of the message sent
2010 by the library. The application may filter the library's
2011 messages according the type. The affected file is the
2012 lib/silcclient/silcapi.h.
2014 * Added two new functions to lib/silcclient/silcapi.h:
2015 silc_client_del_client and silc_client_del_client_by_id.
2016 Affected file lib/silcclient/idlist.c.
2018 * Moved the clientincludes.h from includes/ to silc/ and
2019 serverincludes.h from includes/ to silcd/.
2021 * The modes for the CMODE and CUMODE are now passed as
2022 uint32 for application with COMMAND_REPLY. The affected
2023 file is lib/silcclient/command_reply.c.
2025 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * /WHOIS without arguments shows client's own information.
2028 Affected file lib/silcclient/command.c.
2030 * Changed PING to not accept any arguments. The specs
2031 says that client can ping only the connected server so
2032 requiring an argument is not needed. Affected file is
2033 lib/silcclient/command.c.
2035 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Fixed a fatal bug in private message sending and reception
2038 encryption and decryption when using private message keys.
2039 The implementation was incorrect and did not follow the
2040 specification. It causd that some of the message were
2041 lost since it did not use the sending and receiving keys
2042 as the protocol suggests. This has been fixed and will cause
2043 incompatibilities with older clients when sending private
2044 message encrypted with private message keys. Affected files
2045 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2046 and various other in Irssi SILC Client.
2048 Added `responder' boolean argument to the functions
2049 silc_client_add_private_message_key[_ske] to indicate when
2050 the key is added as responder or initiator of the key
2053 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Removed the silc_ske_check_version function and created
2056 a SilcSKECheckVersion callback. Added also a function
2057 silc_ske_set_callbacks that is now used to set all SKE
2058 callbacks. The callback functions are not given to
2059 the SKE functions anymore, but this function is used to
2062 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2064 * Added `silc_version' argument to the silc_client_alloc
2065 to define the version of the application for the library.
2066 The library will use the version string to compare it
2067 against the remote host's (usually a server) version
2068 string. Affected file lib/silcclient/silcapi.h
2070 * Added the KE protocol context to Key Agreement context
2071 in client library so that we can abort the SKE if it
2072 is in process when we get timeout. Affected file is
2073 lib/silcclient/client_keyagr.c.
2075 * Do not resolve the client ID forever if it returns in the
2076 first time that such client does not exist. This was done
2077 for example with private message. Affected file is
2078 lib/silcclient/client_prvmsg.c.
2080 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Do not add regex.h for WIN32. The affected file
2083 includes/silcincludes.h.
2085 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2086 not work yet 100%. It generates the DLL's automatically
2087 when compiling with --with-win32 under cygwin.
2089 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * lib/contrib/regex.c is not compiled on WIN32.
2093 * Added silc_net_get_socket_opt function to the
2094 lib/silcutil/silcnet.h.
2096 * Added includes/silcwin32.h for WIN32 specific includes
2099 * Do not use ptime structure or any of the posix process
2100 functions on WIN32 in lib/silccrypt/silrng.c.
2102 * Added silc_gettimeofday to provide generic function
2103 for struct timeval on all platforms. Added the function
2104 to lib/silcutil/silcutil.h.
2106 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2109 library as they clearly belong there. As a plus side we
2110 can make the actual socket connection routines platform
2113 Added also new generic function silc_socket_read and
2114 silc_socket_write (that used to be silc_packet_[read/write].
2115 The implementation of these are platform specific.
2117 * Added WIN32 specific routines of silc_socket_[read/write]
2118 to lib/silcutil/win32/silcwin32sockconn.c.
2120 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * Added preliminary support for native WIN32 compilation under
2123 cygwin (using the -mno-cygwin option for GCC) to the
2124 ./configure.in.pre. The --with-win32 now prepares the
2125 compilation for native WIN32.
2127 * Rewrote the SILC Scheduler interface in the file
2128 lib/silcutil/silcschedule.h. The scheduler is now context
2129 based and does not have anymore any global static scheduler.
2130 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2131 and created lib/silcutil/win32 directory for WIN32 based
2134 * Added Unix specific network routines to the
2135 lib/silcutil/unix/silcunixnet.c and the old
2136 lib/silcutil/silcnet.c includes now only generic routines.
2138 Added WIN32 specific network routines to the
2139 lib/silcutil/win32/silcwin32net.c.
2141 * Added Unix specific utility functions from the
2142 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2144 * Added WIN32 SILC Scheduler to the file
2145 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2148 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Do not handle JOIN notify in the server if the target client
2151 is not registered (idata->registered == FALSE). The affected
2152 file is silcd/packet_receive.c.
2154 * Update the nickrec->founder in event_cumode in the Irssi SILC
2155 client. Affected file irssi/src/silc/core/silc-channels.c.
2157 * Fixed the CUMODE_CHANGE notify handling in the server when
2158 server and router are announcing their clients on channels.
2159 Now the mode changes are saved and notified correctly. The
2160 affected file is /silcd/packet_receive.c.
2162 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2163 They really did not replace the cache entry in the ID Cache.
2164 Now they do that. Affected file silcd/idlist.c.
2166 * Fixed the KICK notify handling in the Irssi SILC client to
2167 update the channel records so that the kicked client does not
2168 appear to be on the channel. The affected file is
2169 irssi/src/silc/core/silc-channels.c.
2171 * Always update the conn->current_channel when executing command
2172 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2174 * Fixed the KILL notify handling in Irssi SILC client to remove
2175 the killed client on all channels.
2177 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Fixed the silc_parse_command_line to remove extra spaces
2180 from the start and end of the arguments. Affected file is
2181 lib/silcutil/silcutil.c.
2183 * Cancel and free any active protocol in the function
2184 silc_server_close_connection. Affected file silcd/server.c.
2186 * Cancel and free any active protocol in the function
2187 silc_client_close_connction. Affected file is
2188 lib/silcclient/client.c.
2190 * Do not execute the KILL command for clients that are in
2191 history (ie. they are not in the network). Affected file is
2194 * Fixed KILL notify handling, client does not crash anymore.
2195 Affected file irssi/src/silc/core/silc-channels.c.
2197 * Reduced the default packet buffer size from 2048 to 1024 in
2198 lib/silccore/silcpacket.c.
2200 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2201 counter to the SKE context that is incresed when the SKE library
2202 performs async operation outside the library. If the outside
2203 process frees the SKE context and FREED status will be set
2204 and the library will detect after the sync operation that the
2205 libary is freed. The affected files are
2206 lib/silcske/silcske[_status].[ch].
2208 * Resolve the client entry information in the function
2209 silc_client_channel_message to assure that NULL pointer is not
2210 passed as client entry to the application. */
2212 * Fixed the task timeout calculation to assure that there is
2213 never negative timeouts. The affected file is
2214 lib/silcutil/silcschedule.c.
2216 * Fixed the channel user mode notification sending in server.
2217 It was sent point-to-point to the router (or to server by router)
2218 but it needs to be destined to a channel. The routines now
2219 supports sending the channel user mode notifys to the channels
2220 when announcing clients and channels. Affected files are
2221 silcd/server.c and silcd/packet_receive.c.
2223 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2224 It did not actually replace the old channel entry in the cache.
2225 Affected file lib/silcclient/client_notify.c.
2227 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Fixed a possible crash in silc_packet_send_prepare. It now
2230 assures always that there is enough space in the buffer and
2231 at the tail area of the buffer (for MAC).
2233 Fixed the inbound buffer reallocation in silc_packet_read.
2234 It was old code and did not handle the reallocation correctly.
2237 The affected file is lib/silccore/silcpacket.c.
2239 * Fixed buffer overflow in silc_parse_nickname in the file
2240 lib/silcutil/silcutil.c.
2242 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * make install generates new server keys only if there is not
2247 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2250 Added check that if the NOREPLY is set then we will not send
2251 the away message. This avoids infinite loop of away messages
2252 if both clients are away. The affected file is
2253 lib/silcclient/client_prvmsg.c.
2255 * Fixed client crash if /NICK was given without arguments.
2256 Affected file lib/silcclient/command.c.
2258 * Server does not send the invite list in INVITE command back
2259 to the client if the list was not altered. Added this notion
2260 to the protocol spec as well. Affected file silcd/command.c.
2262 Fixed possible crash in INVITE command by checking the
2263 value of silc_server_get_client_route command.
2265 * Fixed the INVITE notify type handling. The arguments are now
2266 taken in correct order and client does not crash. The affected
2267 file is irssi/src/silc/core/silc-channels.c.
2269 Removed the "Inviting xxx to channel" message from the
2270 client library away and let the application handle it.
2271 Affected file lib/silcclient/command.c. Added that message
2272 to Irssi SILC client's message formats.
2274 * Fixed CMODE command crash in client. It now checks the
2275 amount of arguments correctly and does not crash. The affected
2276 file is lib/silcclient/command.c.
2278 * Do not create new channel automatically in silc_channels_join
2279 but check whether the channel by that name already exists.
2280 Affected file irssi/silc/core/silc-channels.c.
2282 * Do not send the SERVER_SIGNOFF to router if the disconnected
2283 entity was the router. Affected file silcd/server.c.
2285 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2286 SILC client as it was missing from there.
2288 Added the handling of the KICK notify to the Irssi SILC client
2289 as it was missing. Added "you have been kicked" message to
2290 Irssi SILC client's message modules formats.
2292 Added the handing of the KILL notify to the Irssi SILC client
2293 as it was missing. Added the kill message module formats
2296 The affected file is irssi/src/silc/core/silc-channels.c.
2298 * The router did not save the channel mode the server announced.
2299 Affected file silcd/packet_receive.c.
2301 * Fixed a possible crash in INFO command in server. If the
2302 server did not provide the server info it crashed. Affected
2303 file silcd/command.c.
2305 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2307 * Fixed the GETKEY command in the server to check also the
2308 global list. Otherwise the GETKEY would not work correctly
2309 in normal SILC server. Affected file silcd/command.c.
2311 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Fixed GETKEY crash, it crashed if the command did not succseed.
2315 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2318 is now real and not just an macro interface to GMP.
2320 Removed the entire GMP from the source tree and imported new
2321 NSS MPI library instead. Reason for removing GMP is that it is
2322 extremely large and compiles extremely slow. The NSS MPI
2323 is only a few files and compiles in less than 10 seconds.
2324 The speed is also about the same as GMP. The MPI is imported
2325 to lib/silcmath/mpi.
2327 If the system has GMP installed we will still use the GMP.
2328 If it is not then the NSS MPI will be compiled.
2330 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Merged a long nickname (127 characters long) crash bugfix from
2333 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2335 * Merged a freed memory reference bugfix from Irssi CVS tree.
2336 Affected file irssi/src/core/commands.c.
2338 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added the server's public key sving and verification to the
2341 server when performing the SKE. This was missing and the
2342 remote server's (or router's) public key was accepted without
2343 checking whether we have it previously or trust it at all.
2344 Affected file silcd/protocol.c.
2346 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Check in the silc_server_timeout_remote if protocol is active
2349 and make sure that the protocol's final callback is called so
2350 that all memory if freed. Affected file silcd/server.c.
2352 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * silc_server_whois_send_reply crashed the server if the nickname
2355 was 127 characters long. Affected file silcd/command.c.
2357 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Added sanity check to the silc_server_new_client. If the hostname
2360 is provided inside username then check that the provided hostname
2361 really is the same as the resolved one. If the hostname was not
2362 resolved then check it from the public key. Affected file is
2363 silcd/packet_receive.c.
2365 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2366 if the server disconnected us and the connection is not valid
2367 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2369 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2370 the library to the lib/silcutil/silcutil.[ch].
2372 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Close log file after open. Affected file
2375 lib/silcutil/silclog.c.
2377 * Check whether sock == NULL in silc_client_send_packet and return
2378 if it is. Affected file lib/silcclient/silcclient.c.
2380 * Check rec->entry == NULL in the Irssi SILC Client before
2381 sending the channel message. Affecte file is
2382 irssi/src/silc/core/silc-servers.c.
2384 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Merged a splitted window bugfix from Irssi CVS tree. The
2387 affected file is irssi/src/fe-text/textbuffer-view.c.
2389 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2390 It did not print nickname.
2392 * Improved the distributions system a bit.
2394 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2397 irssi/src/fe-text/gui-window.c.
2399 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2400 to in-active server. The affected file is
2401 irssi/src/silc/core/client_ops.c.
2403 * Resolve the client in USERS command reply if the entry does
2404 not have username resolved. The affected file is
2405 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2406 command to WHOIS command to really resolve stuff. The USERS
2407 is not used any more in any critical section so WHOIS can
2408 be used even though it might be slower than IDENTIFY.
2410 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2413 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Changed the protocol API a bit more consistent in the
2416 lib/silccore/silcprotocol.[ch].
2418 * Changed the following headers to ROBODoc format:
2420 lib/silccore/silcpayload.h
2421 lib/silccore/silcprotocol.h
2422 lib/silccore/silcsockconn.h
2424 All core library headers are now formatted.
2426 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Fixed a bug in Irssi SILC client; do not show that you are
2429 server/router operator if you really are not. Affected file is
2430 irssi/src/silc/core/client_ops.c.
2432 * Renamed silc_command_free_payload to silc_command_payload_free.
2433 Affected file lib/silccore/silccommand.h
2435 * Added silcmath.h to include the prototoypes of various routines
2436 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2439 * Changed the following headers to ROBODoc format:
2441 lib/silccore/silcchannel.h
2442 lib/silccore/silccommand.h
2443 lib/silccore/silcid.h
2444 lib/silccore/silcidcache.h
2445 lib/silccore/silcmode.h
2446 lib/silccore/silcnotify.h
2447 lib/silccore/silcpacket.h
2448 lib/silcmath/silcmath.h
2450 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Added checking to the server code not to start the server if
2453 ciphers and stuff are not configured properly. Affected files
2454 silcd/serverconfig.[h] and silcd/server.c.
2456 * Changed the layout of the header files of the public interfaces
2457 in the SILC libraries. The new layout supports ROBODoc
2458 documentation tool (and some others) so that it is easy to create
2459 a library reference manual. All the other headers and source
2460 code must still follow the CodingStyle document. Also source
2461 code must not include these ROBODoc stuffs, only the headers.
2462 Furthermore, all public interface headers must now be named
2463 by using `silc' prefix, example: silcapi.h, silccipher.h.
2464 Some files were renamed due to this. All the other headers
2465 must not be used as public interfaces. I will update the
2466 CodingStyle document later. Changed following headers, so far:
2468 lib/silcclient/silcapi.h
2469 lib/silccore/silcauth.h
2470 lib/silccore/silcprivate.h
2471 lib/silccrypt/silcdh.h
2473 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2477 * Removed silc_client_packet_send_flush from the client library
2478 as it is not needed. Affected file lib/silcclient/client.[ch].
2480 * Added printing of message of unresolved authentication method
2481 to the Irssi SILC client. Added it to the module formats.
2482 Removed the same message from the client library.
2484 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Added new distribution feature, DISTLABEL. Every distribution
2487 can define own preprocessor label that can be used in the
2488 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2489 file distributions, acconfig.h.pre and prepare.
2491 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2493 * Added Makefile.defines_int to include the actual definitions
2494 for Makefile.defines.in. Tested the new distribution system,
2495 created distributions and tested installation.
2497 * Added AWAY message printing to the Irssi SILC client. Added
2498 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2500 * Added SCONNECT command to call the SILC's CONNECT command.
2501 Cannot use CONNECT directly since Irssi uses that internally.
2502 Affected file irssi/src/silc/core/silc-servers.c.
2504 Added ACTION local command. It is same as ME command but takes
2505 the channel as mandatory argument.
2507 Rewrote some of the Irssi's help files to suite for SILC
2510 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2512 * Added Makefile.defines[.in] that should for now on be included
2513 in all Makefile.am file in the source tree. That file includes
2514 all common compilation definitions for SILC source tree.
2516 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2518 * Minor changes to the ./prepare script to change the package
2519 name according the distribution name to the configure.in.
2521 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2523 * Created new distribution system. Added file `distributions'
2524 that defines all the distributions that can be created out of
2525 the SILC source tree. The ./prepare script now reads that
2526 file to determine how to prepare the distributions. The
2527 first argument to the ./prepare is the name of the distribution
2528 and second is the version of the distribution. If given
2529 without arguments it creates the default (toolkit) distribution
2530 with the default version (defined in ./prepare).
2532 All Makefile.am files that are subject to the distributions
2533 are now named as Makefile.am.pre. These are ./Makefile.am
2534 and lib/Makefile.am. Others may be changed later.
2536 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Added invite list, ban list, some key management and connection
2539 error message printing to module formats in the Irssi SILC client.
2541 * Added new silc_client_set_away_message to set the away message
2542 that is back to the person who sent private message. The
2543 affected file lib/silcclient/silcapi.h and the
2544 lib/silcclient/client_prvmsg.c.
2546 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Fixed the private message sending in the Irssi SILC client,
2549 added local command KEY to the Irssi SILC client.
2551 Added key management and key agreement message formats to the
2552 irssi/src/fe-common/silc/module-formats.[ch].
2554 Added USERS (alias WHO) printing, server/router operator
2555 indication and LIST command printing to the module formats.
2557 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Fixed channel joining notify handling, cumode notify handling
2560 from Irssi SILC client.
2562 * Added SILC specific module-formats to the Irssi SILC client so
2563 that SILC specific message hilighting, colors etc is possible.
2564 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2566 Added channel mode, channel user mode, actions, notices,
2567 whois and whowas printing to the the module-formats.c.
2569 * Fixed a bug in channel deletion in the server. The channel
2570 is not left to the cache even if the channel founder auth mode
2571 is set when there are no users anymore on the channel. Affected
2572 file silcd/server.c.
2574 * The silc_net_localhost now resolves the entire hostname including
2575 the domain name. Affected file lib/silcutil/silcnet.c.
2577 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2579 * Changed the ask_passphrase client operation to be ascynchronous.
2580 It has now a completion callback and a context that the
2581 application must call after it has got the passphrase from
2582 the user. Affected files lib/silcclient/silcapi.h,
2583 lib/silcclient/protocol.c, lib/silcclient/command.c and
2586 Added SilcAskPassphrase callback that the application calls
2587 to deliver the passphrase to the library.
2589 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2590 The public key verification and especially a certificate
2591 verification is asynchronous procedure.
2593 Added new SILC_SKE_STATUS_PENDING status to indicate the
2594 request is pending and a callback will be called to finalize
2597 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2598 indicate that remote end did not send its public key (or
2599 certificate), even though we require it. Added check for this
2600 condition in the SKE. This was a security bug, now fixed.
2602 Defined new SilcSKEVerifyCbCompletion callback that is called
2603 when the verification process is completed.
2605 The affected files lib/silcske/silcske_status.h and
2606 lib/silcske/silcske.[ch].
2608 * Changed the verify_public_key client operation to be async
2609 as well. Defined SilcVerifyPublicKey callback that is used to
2610 indicate the success of the public key verification process.
2612 Changed the server and client to use the new async client
2615 * Changed the Irssi SILC client's internal scheduler to be called
2616 twice as many times as it used to be. As a result the client
2617 should be a bit faster now. Affected file is
2618 irssi/src/silc/core/silc-core.c.
2620 * Added support to Irssi SILC client of asynchronous public key
2621 verification and passphrase inquiry. Affected file is
2622 irssi/src/silc/core/silc-core.c.
2624 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2626 * Do not say "You have left channel %s" in client library.
2627 Moved it to the application. Affected files are
2628 lib/silcclient/command.c and silc/client_ops.c.
2630 * Fixed silc_client_get_clients. Command context was not
2631 duplicated and was freed memory in the callback. Affected
2632 file lib/silcclient/idlist.c.
2634 * Do not say "you are now talking..." on JOIN command in the
2635 client library. The appliation must handle it.
2637 * Do not say ".. changed topic to" in command reply in the
2638 client libary. The application must handle it.
2640 * Fixed TOPIC command sending in the client library.
2642 * Fixed a memory leak in silc_client_command_free in the file
2643 lib/silcclient/command.c.
2645 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Imported a modified version of Irssi client to the source tree.
2648 The Irssi will be used to create a new client called
2649 Irssi SILC. Imported to irssi/.
2651 Added silc_core_init_finish function to the Irssi. Affected
2652 file irssi/configure.in.
2654 A lot changes in the Makefile.ams around the irssi tree.
2656 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Do not rehash if the new size is same as the old size of the
2659 hash table, in the silc_hash_table_rehash*. The affected file
2660 lib/silcutil/silchashtable.c.
2662 * Replaced hash_table_del_by_context calls from the server
2663 (when channel->user_list and client->channels) to the
2664 hash_table_del as it is sufficient and faster.
2666 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Added silc_hash_table_list, silc_hash_table_get and the
2669 SilcHashTableList structure to provide an alternative way to
2670 traverse the hash table. The affected files are
2671 lib/silcutil/silchashtable.[ch].
2673 * Changed the server's idlist routines to use the hash table
2674 routines to optimize the code.
2676 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * Replaced the client entry's `channel' list and channel entry's
2679 `user_list' list to hash tables for optimized lookup. Changed
2680 the code to use the hash table interface around the code.
2681 Affected file lib/silcd/idlist.[ch].
2683 * Added `auto_rehash' boolean argument to the function
2684 silc_hash_table_alloc to indicate whether the hash table should
2685 auto-rehash when it thinks is appropriate time. It will
2686 increase the hash table size if the there is twice as much
2687 entries in the table than the size of the table, and will
2688 decrease the size if there are twice as less entries than
2689 the size of the table.
2691 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2695 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * silc_idcache_purge_by_context deletes the entry now by context
2698 as it is supposed to do. Affected file lib/silccore/idcache.c.
2700 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2701 client is not anymore valid (WHOWAS givens the info) and not
2702 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2704 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Removed the `data' and `data_len' arguments from the ID Cache
2707 interfaces and added `name' argument. ID Cache does not handle
2708 anymore the binary data only a names associated with given ID.
2710 * When hashing a Client ID with silc_hash_id the entire ID is
2711 not hashed anymore, instead only the hash of the Client ID is
2712 hashed. This way we can access the Client ID from the cache
2713 with Client ID but with the hash of the ID (which is a hash of
2714 the nickname) as well without any difference in performance.
2716 Added also silc_idcache_find_by_id_one_ext to do one on one
2717 searching when we have the actual ID. Added also function
2718 silc_hash_client_id_compare. The affected files are
2719 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2721 * When hashing the name associated with a ID it is always done
2722 in lowercase. This way we can access the cache without worrying
2723 about case-sensitivity, even though, for example nicknames are
2726 * Fixed a bug in server with channel message sending. It put
2727 wrong ID type as destination ID. The affected file
2728 silcd/packet_send.c.
2730 * silc_idcache_del_by_context now deletes from all hash tables
2731 by context. Affected file lib/silccore/idcache.c.
2733 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Changed the client library to use the new ID Cache interface.
2736 Changes around the source tree.
2738 * Added silc_hash_table_rehash_ext to rehash with specific
2739 hash function. Affected file lib/silcutil/silchashtable.[ch].
2741 * Added silc_hash_string_compare to compare two strings in the
2742 hash table. Affected file lib/silcutil/silcutil.[ch].
2744 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * Added new function silc_idcache_del_by_context into the
2747 lib/silccore/idcache.[ch].
2749 * Changed the server's ID list routines to use the new ID Cache
2750 interface. Changes around the source tree.
2752 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Added silc_hash_table_del[_by_context]_ext functions in to the
2755 lib/silcutil/silchashtable.[ch].
2757 Removed silc_hash_table_find_all* routines and added new
2758 silc_hash_table_find_foreach to replace them.
2760 Added silc_hash_table_replace_ext function as extended
2761 replacing function. Separated the simple hash table interface
2762 from the extended hash table interface in the file
2763 lib/silcutil/silchashtable.h.
2765 * Fixed minor bugs and changed it to use some of the new
2766 hash table functions in lib/silccore/idcache.c
2768 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Added new function silc_hash_table_find_all to return all keys
2771 in the hash table by the specified key. As the hash table is
2772 collision resistant it also makes it possible to have several
2773 duplicate keys in the hash table. This function may be used to
2774 find all of the keys from the hash.
2776 Added user_context arguments to the SilcHashFunction,
2777 SilcHashCompare and SilcHashDestructor to deliver user specified
2780 Added new fuctions silc_hash_table_find[_all]_ext to do
2781 extended lookup with specified hash and compare functions and
2782 specified user contexts.
2784 Added new function silc_hash_table_add_ext to add the key
2785 with specified hash function and user context.
2787 Added new function silc_hash_table_foreach to traverse all
2788 entrys in the hash table. Added SilcHashForeach callback
2791 Added new function silc_hash_table_del_by_context to delete
2792 the entry only if the context associated with the key matches.
2794 Affected files are lib/silcutil/silchashtable.[ch].
2796 * Removed silc_hash_[server/client/channel]_id and added just
2797 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2798 silc_hash_id_compare to compare two ID's using as the hash table
2799 comparison function. Added also silc_hash_data to hash
2800 binary data and silc_hash_data_compare to compare it.
2802 * Removed silc_idlist_find_client_by_hash as it is not needed
2803 anymore. Affected file silcd/idlist.[ch].
2805 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2806 to use internally the SilcHashTable. The new ID Cache is a lot
2807 faster than the old one. Some of the ID Cache interface was also
2808 rewritten and obsolete and stupid functions were removed.
2810 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Added entry_count field to the SilcHashTable to keep the number
2813 of the entries in the table. Implemented the function
2814 silc_hash_table_rehash. Added new function
2815 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2817 Fixed a minor bug in silc_hash_table_free.
2819 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2820 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2821 into the lib/silcutil/silcutil.[ch].
2823 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Implemented a collision resistant hash table into the
2826 lib/silcutil/silchashtable[ch]. See the header and the source
2827 for the SilcHashTable API.
2829 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Merged dotconf version 1.0.2 into lib/dotconf.
2833 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Do not compile anything in lib/silcsim/* if the SIM support
2836 is not enabled. The tree should now compile without problems
2839 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * Compiled the SILC under cygwin. Compiled and tested briefly
2842 without problems. More tests needed. The SIMs didn't compile
2845 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2847 * Fixed possible crash in silc_get_username in the
2848 lib/silcutil/silcutil.c.
2850 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Fixed a va_arg in silc/client_ops.c.
2854 * Oops, RC5 routines were named AES and caused some problems
2855 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2857 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Added new SilcIDIP structure into the lib/silccore/id.h and
2860 replaced the old `ip' fields from all SILC ID's to that type.
2861 This is a step towards IPv6 support.
2863 The silc_id_get_len takes now the ID as an extra argument.
2864 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2865 both IPv4 and IPv6 based ID's.
2867 The affected files are lib/silccore/id.[ch] and other files
2868 around the tree using these routines.
2870 * Removed the ID length arguments in server from various
2871 silc_server_send_notify_* routines -> they are not needed
2874 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Fixed memory leak in silc_encode_pem_file in the file
2877 lib/silcutil/silcutil.c.
2879 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Check minor version as well in the SKE. Affected files are
2882 silcd/protocol.c and lib/silcclient/protocol.c.
2884 * Added --identifier option to the server so that an identifier
2885 can be when creating the public key for the server. Affected
2886 file is silcd/silcd.c.
2888 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2889 lib/silccrypt/silcpkcs.c.
2891 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Register default ciphers and stuff when using -C option with
2894 the server. Affected file sildc/silcd.c.
2896 * Put back the servers public key filename format, it is better
2897 than the new one. For now, the client keys are saved with the
2898 new filename format. The affected file silc/client_ops.c.
2900 * Implemented the Cipher API for the rest of the ciphers that
2901 did not implement it or implemented it the wrong way.
2903 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Register default ciphers and stuff when using the -S option
2906 in the client. Affected file silc/silc.c. Same also when
2907 creating new key pair with -C option.
2909 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2911 * Fixed the silc_verify_public_key client operation function to
2912 save the public keys differently. The fingerprint is now
2913 used as filename and not the hostname. This way also the
2914 client keys are saved uniquely and not with hostnames. The
2915 affected file is silc/client_ops.c.
2917 * Trimmed the silc_hash_fingerprint function to remove extra
2918 whitespaces from the end of the fingerprint. The affected
2919 file is lib/silccrypt/silchash.c.
2923 * Added silc_cipher_register_default function to register all
2924 default ciphers. It can be used when configuration files
2925 does not exist and the application does not want any specific
2926 ciphers in any specific order.
2928 The SilcDList is now used as silc_cipher_list dynamically
2929 allocated cipher list. Removed the static list all together
2930 and now all ciphers must be allocated to the dynamic list.
2931 The silc_cipher_alloc routine was changed to check only the
2934 All silc_cipher_* routines that used to return int returns
2937 The affected files lib/silccrypt/silccrypt.[ch].
2939 * The same thing was done to silc_hash_* as for silc_cipher_*
2940 routines. Affected files lib/silccrypt/silchash.[ch].
2942 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2943 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2944 Added also silc_pkcs_[un]register[_default] functions.
2945 Removed the data_context from the PKCS API.
2947 * Added silc_hmac_register_default function to register default
2948 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2949 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2950 to unregister all hmacs at once.
2952 * Register the default ciphers, hash functions, PKCSs and HMACs
2953 if client's configuration file does not exist. The affected
2956 * The client did not load the hash functions from the SIM
2957 modules at all. Added support for this. Affected file is
2958 silc/clientconfig.c.
2960 * When decoding public key with silc_pkcs_public_key_decode, check
2961 the supported algorithm only if PKCS are registered. Affected
2962 file lib/silccrypt/silcpkcs.c. The same was done with the
2963 silc_pkcs_private_key_decode.
2965 * Fixed the SILC List routines to keep the list always in order.
2966 It used to change the list's order when traversing the list but
2967 not it preserves the order. Affected file lib/trq/silclist.h.
2969 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Added the client library to use the SilcSocketConnection's
2972 reference counter (by silc_socket_dup) to prevent the bug that
2973 the socket object may be freed underneath async operation.
2975 * The name resolv library checking fixes in the configure.in.pre.
2978 * Created new version of the protocol drafts for future
2979 development. The -03 drafts are the ones that will be changed
2980 in the trunk now and the -02 will remain as they are.
2982 * Send list of CUMODE notifys to the router when announcing
2983 the channel users to the router. Affected file silcd/server.c.
2984 If the router receiving channel founder CUMODE for a channel
2985 that already has channel founder it will send CUMODE notify
2986 to the sender to remove the channel founder rights from the
2987 announced client. Affected file silcd/packet_receive.c.
2989 * The CUMODE notify may now use Server ID as well as the entity
2990 who changes the mode. Updated protocool specs.
2992 * Updated INSTALL and README files.
2994 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * New web pages in the http://silc.pspt.fi. The pages was
3001 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3003 * Implemented the [DenyConnectin] config section in the server.
3004 Added silc_server_config_denied_conn to check whether incoming
3005 connection is denied. Affected file silcd/serverconfig.[ch].
3007 * Do not check the ports when checking the incoming configuration
3008 data if the port is 0, meaning any. Affected file is
3009 silcd/serverconfig.c.
3011 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Fixed buffer overflow in silc_string_compare in the file
3014 lib/silcutil/silcutil.c.
3016 * Fixed double free in silc_server_command_leave in the file
3019 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Fixed the version checking in the server. Affected file is
3024 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Fixed the configuration data fetching when accepting new
3027 connections in the server. Affected file silcd/server.c.
3029 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Added `sender_entry' argument to the function
3032 silc_server_packet_relay_to_channel so that we can check
3033 whether some destination actually belongs to the same route
3034 the sender belongs (ie, we must not resend the packet to the
3035 sender). Affected file silcd/packet_send.[ch].
3037 * Added `servername' field to the SilcClientEntry in the server
3038 to hold the name of the server where client is from. Affected
3039 file is silcd/idlist.h.
3041 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3043 * Moved the channel message encrypting in the router betwen
3044 router connections from silc_server_channel_message to the
3045 silc_server_packet_relay_to_channel since we want to check
3046 whether we have anybody channel before encrypting anything.
3047 Affected files silcd/packet_[receive/send].c.
3049 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Fixed the [AdminConnection] server config section to support
3052 multiple entries. Affected file silcd/serverconfig.c.
3054 * Added support into the server to check the validity of the
3055 incoming connection before executing any KE or authentication
3058 * The connection configuration is now saved to the KE and
3059 connection auth protocol contexts and not fetched anymore in
3060 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3062 * The local hosts listenning address and port is also resolved
3063 now when starting the server. We want to have the socket object
3064 to include the real address and port for the listener. Added
3065 new function silc_net_check_local_by_sock into the files
3066 lib/silcutil/silcnet.[ch].
3068 * Fixed a broadcast bug in server -> do not broadcast if we
3071 * Fixed a routing bug. Do not route broadcast packets ever.
3072 Broadcast packets must be processed always and not routed since
3073 they may be destined to some other host than yourself and thus
3074 would get routed without no good reason. Affected file is
3077 * Added function silc_server_config_is_primary_route to check
3078 whether primary router connection has been configured (a router
3079 configuration that we are initiating). If there is not, we
3080 will assume that there is only two routers in the SILC network
3081 and we will use the incoming router connection as our primary
3082 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3084 * Changed the order of the broadcasting. Broadcast _after_ the
3085 packet has been processed not before. Affected file is
3088 * Fixed a [ClientConnection] parsing bug. The port was never
3089 parsed correctly thus resulting to port 0. Affected file
3090 silcd/serverconfig.c.
3092 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3093 argument and did not set the broadcast packet flag. Affected
3094 file silcd/packet_send.c. Fixed same bug in the function
3095 silc_server_send_notify as well.
3097 * If we receive NEW_ID packet for our own ID in the server, ignore
3100 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Removed the nickname from the Private Message Payload.
3105 Updated the code and the protocol specs.
3107 * Updated protocol specs for submitting to the IETF.
3109 * Tweaked the Random Number Generator a bit. Affected file
3110 lib/silccrypt/silcrng.c. Exported a new function
3111 silc_rng_[global]_add_noise which can be used to add more
3114 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3116 * Do not parse packets with different timeout when protocol
3117 is active -> may cause problem with rekey. Affected file
3120 * When server receives signoff notify it must not create
3121 new channel key if the client is on any channels since the
3122 sender of the signoff notify will create it.
3124 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Added printing of error messages during SKE protocol from the
3127 failure packet sent by server during SKE. Affected file
3130 * Removed the client's failure_callback handling with timeout
3131 and handle it immediately when received.
3133 * The SKE library returned wrong type in SUCCESS and FAILURE
3134 packets. They must be 32 bit MSB not 16 bit MSB.
3136 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Ok, rewrote the logic of the re-key and now it seems to work.
3139 I tested it on high traffic with frequent re-keys without
3140 problems. Added hmac_receive (and renamed hmac to hmac_send)
3141 in SilcClientConnection in lib/silcclient/client.h and
3142 in SilcIDListData in silcd/idlist.h. Also, removed the
3143 SilcPacketParserContext's cipher and hmac fields as they are
3144 not needed anymore and actually caused some problems when
3145 the ciphers and hmac's changed underneath the packet parser.
3147 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * If re-key protocol is active then process the incoming packets
3150 synchronously since we must assure that icoming packets encrypted
3151 with the old key is processed before the new keys is set to
3152 use. This is true other packets than for REKEY packets.
3153 Affected file silcd/server.c. The same was done to client library
3154 as well, affected file lib/silcclient/client.c.
3156 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Fixed bug in client and server to accept the force send if
3159 the packet is send from silc_[server/client]_packet_process
3160 function. Otherwise the packets are never delivered, oops.
3162 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Disable force sending of packets when REKEY protocol is active.
3165 We must assure that no packet is sent directly when rekey is
3166 performed. All packets must be sent through packet queue.
3167 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3168 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3169 function is silc_[server/client]_packet_send_real to check
3172 * Replaced the SIM paths from example config files to
3173 /usr/local/modules. Also, make install creates now
3174 /usr/local/silc/logs directory to hold all the SILC server
3177 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Made the configure.in.pre work on Solaris. Patch by salo.
3181 * Made all ciphers compatible with non-x86 machines. Defined
3182 CBC mode macros into lib/silccrypt/ciphers_def.h.
3184 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Fixed the make install.
3188 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * When MAC computation fails the silc_packet_decrypt returned 0
3191 even though it was supposed to return -1. Fixed this. The
3192 affected file is lib/silccore/silcpacket.c.
3194 * Do not replace the config files in /etc/silc (in make install)
3195 if they already exist. Affected file ./Makefile.am.
3197 * Do not send re-key packets immediately but through packet queue.
3198 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3200 * Changed silc_net_check_host_by_sock to return FALSE if the
3201 IP/DNS could not be resolved. Though, it returns the IP address
3202 now even if it could not resolve it (but returns also FALSE).
3203 Affected file lib/silcutil/silcnet.[ch].
3205 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3213 contents of the specified public key file.
3215 * Changed the PKCS api to return the public key length when
3216 setting the public key.
3218 * Fixed a fatal bug in the public and private key file loading.
3219 Affected file lib/silccrypt/silcpkcs.c.
3221 * Execute the packet parsing for client with zero (0) timeout
3222 if the protocol is active. Affected file silcd/server.c.
3224 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3226 * Made the key generation options to the silcd program. Added
3227 -C option, equivalent to client's option.
3229 * Added new [ServerKeys] config section to the server. It
3230 configures the server's public and private key.
3232 * Defined generic Public Key Payload into the protocol
3233 specification to send specific type of public keys and
3236 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3237 public key or certificate.
3239 * Implemented the GETKEY command to the server and to the
3240 client library and on user interface.
3242 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3246 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3248 * Added SilcServerRekey context into silcd/idlist.h.
3250 * Added the PFS support as defined in the specification to the
3251 SKE protocol. Affected files lib/silcske/*.c.
3253 * Added `ske_group' field to the SilcServerRekey context to hold
3254 the number of the SKE group that is used with PFS in re-key.
3255 Affected file silcd/idlist.h.
3257 * Added PFS re-key support to the server. Affected file is
3260 * Added silc_protocol_cancel to cancel execution of the next
3261 state of the protocol. Affected file is
3262 lib/silccore/silcprotocol.[ch].
3264 * Added the re-key support with and without PFS to the client
3265 library. Re-key is performed once in an hour, by default.
3267 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3268 Added silc_client_rekey_callback and silc_client_rekey_final.
3269 Affected files are lib/silcclient/protocol.[ch] and
3270 lib/silcclient/client.[ch].
3272 * Removed the `hmac_key' and `hmac_key_len' fields from the
3273 SilcClientConnection structure; not needed. Affected file is
3274 lib/silcclient/client.h.
3278 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Do not ask whether user wants to use the negotiated private key
3281 for private messages, just use it. Affected file is
3282 silc/local_command.c.
3284 * Added `send_enc_key' and `enc_key_len' fields to the
3285 SilcIDListData structure since they are needed in the re-key
3286 phase. Affected file is silcd/idlist.[ch].
3288 * Implemented the simple re-key protocol into the server.
3289 Affected files silcd/server.c and silcd/protocol.[ch]. The
3290 re-key will be performed once in an hour, by default.
3292 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3293 Added silc_server_rekey, silc_server_rekey_callback and
3294 silc_server_rekey_final.
3296 * Removed Tunneled flag from the protocol. Updated the code
3297 and the specifications.
3299 * Adde `pfs' field to the SilcIDListData to indicate whether
3300 the PFS is to be performed in the re-key. Affected file is
3303 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3305 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3306 int64 of at least the xintXX size. If void * is less that 4
3307 bytes uint32 * will be used. Defined bool as boolean.
3309 * Changed _ALL_ unsigned long and unsigned int to uint32,
3310 unsgined short to uint16 in the source tree.
3312 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3313 not handle clients that has entry->data.registered == FALSE.
3314 They are not in the network anymore. Affected file is
3317 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Implemented the sending of the SERVER_SIGNOFF notify in the
3320 server. Affected file is silcd/server.c.
3322 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3323 Added also silc_notify_payload_encode_args into the
3324 lib/silccore/silcnotify.[ch].
3326 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3327 Affected file silcd/packet_receive.c.
3329 * Implemented the SERVER_SIGNOFF notify handling in the client
3330 library. Affected file lib/silcclient/client_notify.c. Also,
3331 implemnted the printing of the SERVER_SIGNOFF info to the
3332 application. Affected file silc/client_ops.c.
3334 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3335 if the deleting was successful. Affected file silcd/idlist.[ch].
3337 * Added support for public key authentication in the connection
3338 authentication protocol in the client library. Affected file
3339 lib/silcclient/protocol.c.
3341 * Changed the server's silc_idlist_get_clients_by_* interface
3342 to support already allocated array so that new entries may be
3343 added to pre-allocated array. Affected file silcd/idlist.[ch].
3344 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3345 and command replies.
3347 * All command reply functions in the server now calls the
3348 pending command callback even if error occured. This way the
3349 error will be delivered to the client as well. Affected files
3350 silcd/command.c and silcd/command_reply.c.
3352 * Fixed INFO command to return local server's info if no server
3353 was provided. Affected file lib/silcclient/command.c.
3355 * Removed RESTART command for good. Updated the code and the
3358 * Rewrote parts of the task system. It is a bit simpler now.
3359 Removed unsued task priorities. The affected files are
3360 lib/silcutil/silctask.[ch].
3362 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Moved the USERS printing from the library to the application.
3365 Affected files lib/silcclient/command.c and silc/client_ops.c.
3367 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Added channel key re-key support. The re-key is perfomed
3372 only by the router and is done once in an hour. Added `rekey'
3373 field to the SilcChannelEntry in the server. Affected files
3374 silcd/server.c and silcd/idlist.h.
3376 * Added silc_task_unregister_by_context into the file
3377 lib/silcutil/silctask.[ch].
3379 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Added SILC_UMODE_GONE mode to indicate when the client is not
3382 present in the SILC network. Added also support to the local
3383 command AWAY that will set this mode. Added support of showing
3384 "xxx is gone" in WHOIS command. The USERS command shows the
3385 gone status as well.
3387 * Fixed setting server and router operator privileges in the
3388 server's UMODE command. Affected file silcd/command.c.
3390 * Merged the SKE KE1 and KE2 payloads into one payload. The
3391 new KE payload is equivalent to the old KE2 payload.
3393 Cleaned up the SKE Start Payload parsing. It now uses the
3394 simple buffer unformatting to do the parsing. A lot faster
3397 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3398 to the SKE that is used to indicate whether both of the SKE
3399 parties should perform authentication. By default only the
3400 responder performs authentication. By setting this flag also
3401 the initiator must do authentication. By default it is unset
3402 since in normal SKE case, client to server connection, only
3403 the responder should do authentication. When doing SKE between
3404 two clients both should perform authentication. Updated the
3405 code and the protocol specs.
3407 * A little fix to IDENTIFY command in the server. Search the
3408 client first by hash not nickname. Affected file is
3411 * Fixed the silc_client_close_connection to support closing
3412 the client to client connections wihtout deleting too much
3413 data. Affected file lib/silcclient/client.c.
3415 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3416 are received if protocol used to be active but is not anymore
3417 the application would crash due to NULL pointer dereference.
3418 Affected files silcd/server.c and lib/silcclient/client.c.
3420 * Added `hash' field to the SilcClientConnection to include
3421 the hash function negotiated in the SKE protocol.
3423 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3424 to set the channel founder authentication data. A client can
3425 claim the founder rights later by providing the authentication
3426 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3427 This way the channel founder can regain the channel founder
3428 privileges even it is left the channel. This works only on
3429 local server and the client must be connected to the same
3430 server to be able to regain the founder rights. Updated the
3431 protocol specs accordingly.
3433 Added support to the CMODE command in the client to set the
3434 founder auth data. Read the README to see how to set it.
3436 Added support to the CUMODE command to claim the founder
3437 rights. Read the README to see how to do it.
3439 Added support for the founder authentication to the Channel
3440 Entry in the server. Affected file silcd/idlist.h.
3442 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3443 server's CMODE command. Affected file silcd/command.c.
3445 * Added the following new functions into lib/silccore/silcauth.[ch]:
3446 silc_auth_get_method and silc_auth_get_data.
3448 * The server now saves the remote hosts public key to the
3449 SilcIDListData pointer. Affected file silcd/protocol.c.
3451 * The normal server now does not remove the channel entry from
3452 the cache if the founder authentication data is set. It used
3453 to remove it if the founder was the last one on the channel on
3454 the server and left the channel. The auth data is saved and
3455 if the channel is re-joined later the old entry is used with
3456 the old auth data. Affected files silcd/command_reply.c and
3459 * Removed the `pkcs' field from the SilcIDListData structure
3460 in the server; it is not used. Affected file silcd/idlist.h.
3462 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Fixed packet processing on slow links. Partial packets were
3465 never re-processed because the incoming data buffer was cleared
3466 by the application. Application must not directly clear the
3467 sock->inbuf, the packet processing routines handle it. Fixed
3468 this in client library and in server.
3470 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Fixed the WHOIS and IDENTIFY send reply function to really
3473 check whether to send list or just one entry. Affected file
3476 * Cleaned up the LEAVE command's channel key distribution. The
3477 affected file silcd/command.c.
3479 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3480 can enforce the channel mode as well. In that case the ID
3481 includes the ID of the server. The code now enforces the
3482 mode change if the router have different mode than the server.
3484 * The notify client operation with CMODE_CHANGE notify can now
3485 return NULL client_entry pointer if the CMODE was not changed
3486 by client. Application must check for this.
3488 * Added <Server ID> argument to INFO command to support server
3489 info fetching by Server ID.
3491 * Added silc_server_announce_get_channel_users to get assembled
3492 packets of channel users of the specified channel. Affected
3493 file silcd/server.[ch].
3495 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3496 was freed underneath the ID Cache.
3498 * Re-announce clients when the server received CHANNEL_CHANGE
3499 notify from the router. Affected file silcd/packet_send.c.
3501 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3504 crashed since it did not handle the fact that there is no cipher
3505 called "3" and didn't check the error condition. Now fixed.
3507 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3508 flag. It can be used to send message requests.
3510 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Implemented the RESTART command in the client.
3514 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3515 notice type messages. Added notice printing to the user
3518 * The channel keys are not re-generated if the channel's mode
3519 is PRIVKEY, ie private key on the channel exists. Affected
3520 files silcd/server.c and silcd/command.c.
3522 * Fixed a little bug in channel message delivery when channel
3523 private keys are set in the server. Affected file is
3524 silcd/packet_send.c.
3526 * Changed the setting on channel->on_channel = TRUE from the
3527 silc_client_save_channel_key to the JOIN command reply. The
3528 key payload is not received if the private channel key is set.
3529 Affected file lib/silcclient/command_reply.c and the
3530 lib/silcclient/client_channel.c.
3532 * When the CMODE_CHANGE notify is sent and the channel private
3533 key mode is removed the channel key must be re-generated in
3534 other cells as well. Added this support for the router in the
3535 silcd/packet_receive.c.
3537 * Added new local command NOTICE to send notice message on
3538 channel. Affected file silc/local_command.[ch].
3540 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Added new local command ME to the client. It is used to send
3543 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3544 some action. Affected file silc/local_command.[ch].
3546 * Changed channel_message and private_message client operations
3547 to deliver the message flags to the application. Added also
3548 the `flags' arguments to the silc_client_send_channel_message
3549 and silc_client_send_private_message functions. Affected file
3552 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Redefined the Private Message Payload to support private message
3555 keys and to support the new private message flags. Updated
3556 the protocol specs. Flags makes it possible to have for example
3557 CTCP style messages.
3559 * Added new type SilcPrivateMessagePayload and defined an API
3560 for it in the lib/silcclient/silcprivate.[ch].
3562 * Tested private message private keys successfully. Tested the
3563 private message key set, unset and list commands with the new
3566 * Redefined the Channel Message Payload to include the channel
3567 message flags (equal with private message flags) to support
3568 for example CTCP style messages.
3570 * Defined some of the message (for channel and private message)
3571 flags. Updated the protocol specs and added the flags to the
3572 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3574 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Added SilcKeyAgreementStatus type to the key agreement routines
3577 to indicate the current status and error if one occured.
3578 The status types are defined in the lib/silcclient/silcapi.h.
3580 * Added new local command KEY that is used to set and unset private
3581 keys for channels, set and unset private keys for private messages
3582 with remote clients and to send key agreement requests and
3583 negotiate the key agreement protocol with remote client. The
3584 key agreement is supported only to negotiate private message keys,
3585 it currently cannot be used to negotiate private keys for channels,
3586 as it is not convenient for that purpose.
3588 * Fixed a minor pending callback setting bug in the function
3589 silc_client_get_client_by_id_resolve, now the function works.
3590 Affected file lib/silcclient/idlist.c.
3592 * Added function silc_net_get_local_port to get local bound
3593 port by socket. Added to lib/silcutil/silcnet.[ch].
3595 * Added `sockets' and `sockets_count' fields to the SilcClient
3596 object. They hold the sockets of the listenning sockets in
3597 the client. Listenning sockets may be for example the key
3598 agreement server. Affected file lib/silcclient/client.[ch].
3599 Added functions the silc_client_add_socket and the
3600 silc_client_del_socket. They are exported to the application
3603 * Added ~./silc/clientkeys to support other client's public keys.
3605 * Renamed verify_server_key client operation to verify_public_key
3606 and added one argument to indicate the type of the connection
3607 (server, client etc.).
3609 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Added silc_server_connection_auth_request to handle the
3612 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3613 silcd/packet_receive.[ch].
3615 * Added silc_server_send_connection_auth_request into the
3616 silcd/packet_send.c to send the connection auth request packet.
3618 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3621 * Fixed the public key authentication in responder side in the
3622 server. The `auth_data' pointer includes the SilcPublicKey
3623 not the path to the public key. Affected file silcd/protocol.c.
3625 * Implemented the public key authentication in the initiator side
3626 in the server. Affected file silcd/protocol.c.
3628 * Removed the [RedirectClient] config section from the server
3629 configuration. Is not needed and I don't want to implement it.
3631 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Cleaned up the CMODE command in the server. It now works
3634 correctly and supports all the modes defined in the protocol.
3635 Affected file is silcd/command.c.
3637 * Added `hmac_name' field to the SilcChannelEntry in the server
3638 to hold the default HMAC of the channel. It can be set when
3639 creating the channel (with JOIN command). Affected files
3642 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3643 type to indicate the change of the current cipher and hmac
3644 on the channel. Client can safely ignore the <cipher> argument
3645 (if it chooses to do so) since the CHANNEL_KEY packet will
3646 force the channel key change anyway. The <hmac> argument is
3647 important since the client is responsible of setting the new
3648 HMAC and the hmac key into use.
3650 * Fixed the CMODE command in the client library as well.
3652 * Tested CMODE command in router environment successfully.
3654 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Show the version of the remote client (or server) when connecting
3657 to the server. It is logged to the log file. Affected file
3658 is silcd/protocol.c.
3660 * Fixed the KILLED notify handling in the client library. The
3661 client must be removed from all channels when receiving the
3664 Also, do not remove the client entry when giving the KILL
3665 command but when the KILLED notify is received.
3667 * Removed silc_idlist_find_client_by_nickname from the server.
3668 Not needed anymore. Affected files silcd/idlist.[ch].
3670 * Implemented the CHANNEL_CHANGE notify type handling to the
3671 server. Affected file silcd/server.c.
3675 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Added silc_server_send_notify_invite to send the INVITE
3678 notify between routers.
3680 * Implemented the INVITE command correctly to the server.
3682 * Implemented the INVITE notify type handling in the server.
3684 * Implemented the INVITE command to the client library and on the
3687 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added function silc_server_get_client_resolve to find the
3690 client entry by ID from all ID lists and then resolve it
3691 (using WHOIS) if it cannot be found. Affected file is
3694 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3696 * Implemented the BAN command to the client library.
3698 * The JOIN command in the server now checks the invite list
3701 * Changed the silc_command_reply_payload_encode_va and the
3702 silc_command_payload_encode_va to support that if argument is
3703 NULL it ignores and checks the next argument. Affected file
3704 lib/silccore/silccommand.c.
3706 * Added silc_server_send_notify_ban to send the BAN notify
3707 type between routers.
3709 * Chaned the silc_notify_payload_encode to support that if
3710 argument is NULL it ignores and checks the next argument.
3711 Affected file lib/silccore/silcnotify.c.
3713 * Tested ban lists in router environment successfully.
3715 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Implemented BAN command to the server, in silcd/command.[ch].
3719 * Removed the BAN and INVITE_LIST modes from the CMODE command
3722 * Added function silc_string_match to regex match two strings.
3723 Affected files lib/silcutil/silcutil.[ch].
3725 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Redefined parts of the SilcChannelEntry in the server to support
3728 the new ban and invite lists.
3730 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Redefined the INVITE command. The same command can be used to
3733 invite individuals to the channel but also to manage the invite
3734 list of the channel (to add to and remove from the invite list).
3735 Updated the protocol specs.
3737 * Added new command SILC_COMMAND_BAN that can be used to manage
3738 the ban list of the channel. Updated the protocol specs.
3740 * Removed the channel modes: the SILC_CMODE_BAN and the
3741 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3742 in the CMODE command. The equivalent features are now available
3743 using INVITE and BAN commands. Updated the protocol specs.
3745 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3746 in the network about change in the current ban list. The notify
3747 type is not used by the client.
3749 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3750 support the invite lists.
3752 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Added new function silc_string_regexify that converts string
3755 including wildcard characters into regex string that can
3756 be used by the GNU regex library. Added into the file
3757 lib/silcutil/silcutil.[ch].
3759 Added silc_string_regex_combine to combine to regex strings
3760 into one so that they can be used as one regex string by
3761 the GNU regex library. Added into the file
3762 lib/silcutil/silcutil.[ch].
3764 Added silc_string_regex_match to match two strings. It returns
3765 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3767 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Imported GNU regex to the soruce tree into lib/contrib.
3770 Fixed some compiler warning from the regex.c.
3772 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Fixed MOTD command in the server to work in router environment.
3776 * Fixed the MOTD command in the client library to support
3777 the server argument in the command.
3779 * Added `nickname_len' argument to the silc_idlist_add_client
3780 in the server, as the `nickname' argument may be binary data
3783 * Added silc_idlist_get_channels to return all channels from
3786 * Implemented LIST command to the server. Affected file is
3789 * Implemented the LIST command to the client library and on the
3792 * Added [<user count>] argument to the LIST command reply.
3793 With private channels the user count is not shown.
3795 * Updated TODO and README.
3797 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * The client entry's data.registered must be TRUE even with
3800 global client entry on global client list. The data.registered
3801 is used to check whether the client is anymore in the network,
3802 for example with WHOWAS command so it must be valid.
3804 * Fixed the WHOWAS command in the server. It now actually works
3805 in router environment. Added function into silcd/command_reply.c
3806 silc_server_command_reply_whowas_save.
3808 * Added silc_idlist_purge function to the silcd/idlist.c
3809 to periodically purge the ID Cache.
3811 * Fixed INFO command in the server. It works now in router
3812 environment. Added <server name> argument to the INFO command
3813 reply. Updated the protocol specs.
3815 * Fixed minor bug in silc_idcache_purge to not purge if the
3816 expire value is zero.
3818 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3819 they were buggy because of the WHOWAS information.
3821 * Fixed local command MSG to handle the async resolving of
3822 the remote client properly. It used to fail the first MSG.
3823 Affected file silc/local_command.c.
3825 * Added `data_len' field to SilcIDCache context.
3827 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Update TODO. Todo in commands in the server.
3831 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3834 used by routers as broadcast packet to inform other routers
3835 about the changed user mode.
3837 Implemented the notify handling in the server. Affected file is
3838 silcd/packet_receive.c. Added the function
3839 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3841 * Added new generic Channel Payload and deprecated the New Channel
3842 Payload. The New Channel Payload is now the generic Channel
3845 * Added new argument `mode' to the silc_server_send_new_channel
3846 as it is required in the Channel Payload now.
3848 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3849 and created a new and real SilChannelPayload to represent the
3850 new generic Channel Payload. Implemented the encode/decode
3851 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3853 * Added silc_server_get_client_channel_list to return the list
3854 of channels the client has joined for WHOIS command reply.
3855 Affected file silcd/server.[ch].
3857 * Implemented the channel list sending in the WHOIS command reply
3858 in server and in the client.
3860 Implemented the channel list displaying on the user interface
3861 as well. Affected file silc/client_ops.c.
3863 * Added silc_channel_payload_parse_list to parse list of Channel
3864 Payloads. It returns SilcDList list of SilcChannelPayloads.
3865 Client for example can use this function to parse the list of
3866 channels it receives in the WHOIS command reply. The caller
3867 must free the list by calling silc_channel_payload_list_free.
3868 Affected files lib/silccore/silcchannel.[ch].
3870 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Added one new argument <user mode> to the WHOIS command reply
3873 to return the mode of the user in SILC. Updated the protocol
3876 Implemented it to the server and client.
3878 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Fixed the mode printing on the user interface on joining.
3881 Affected file silc/client_ops.c.
3883 * Implemented the UMODE command and user modes in general to the
3884 client library and to the user interface.
3886 * Implemented the UMODE command to the server.
3888 * The server now sends UNKNOWN_COMMAND error status if client sends
3889 unknown command. Affected file silcd/command.c.
3891 * All server commands now handle the command identifier the right
3892 way when sending the command reply to the client. The client can
3893 use to identify the command replies with the identifier.
3895 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Added silc_server_get_client_route to resolve the route to
3898 the client indicated by the client ID. Affected file is
3901 * Added silc_server_relay_packet as general function to relay
3902 packet to arbitrary destination. This deprecates functions
3903 like _send_private_message_key, _relay_notify etc. Affected
3904 file is silcd/packet_send.[ch].
3906 Removed silc_server_send_key_agreement,
3907 silc_server_send_private_message_key and
3908 silc_server_packet_relay_notify functions from the file
3909 silcd/packet_send.[ch].
3913 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3914 server. Affected file silcd/packet_receive.[ch].
3916 * Implemented the KILL command to the client. Implemented the
3917 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3918 Affected files lib/silcclient/command[_reply].c and
3919 lib/silcclient/client_notify.c. Implemented the KILL notify
3920 printing in the user inteface.
3922 * Fixed a lot silc_parse_nick memory leaks from the client
3923 library in the file lib/silcclient/command.c.
3925 * Changed the silc_server_send_notify_on_channels's `sender'
3926 argument from SilcSocketConnection to SilcClientEntry to
3927 check the sender as entry and not as connection object and not
3928 to send to the client provided as argument. The affected file
3929 is silcd/packet_send.[ch].
3931 * The notify packets that are destined directly to the client used
3932 to not to be processed by the server. Now changed that and the
3933 server processes all notify packets. After relaying the packet
3934 to the client the notify packet is processed in the server.
3936 * The silc_server_free_client_data now checks whether there is
3937 pending outgoing traffic for the client and purges the data to
3938 the network before removing the client entry.
3940 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3943 an client is killed from the SILC Network. Updated the protocol
3946 Added new function silc_server_send_notify_killed to the
3947 silcd/packet_send.[ch].
3949 * Added function silc_server_packet_relay_notify to relay notify
3950 packets that are destined directly to a client. In this case
3951 the server does not process the notify packets but merely relays
3952 it to the client. Affected file silcd/packet_send.[ch].
3954 Added also silc_server_packet_process_relay_notify to check
3955 whereto relay the notify. Affected file is
3956 silcd/packet_receive.[ch].
3958 * Implemented the KILL command to the server.
3962 * Added the backup schema desgined last fall to the protocol
3963 specs for everyone to see. The specification is in the
3964 *-spec-xx.txt draft and the packet type definitions for the
3965 backup routers is in *-pp-xx.txt draft. Thusly, added also
3966 new packet type SILC_PACKET_CELL_ROUTERS.
3968 * A big security problem in the implementation discovered. The
3969 signoff of an client did not cause new channel key generation
3970 which it of course should've done. The channel keys must be
3971 always re-generated when client leaves (or signoffs) the channel.
3972 The silc_server_remove_from_channels funtion now handles
3973 the channel key re-generation.
3975 * Added `sender' argument to the silc_server_send_notify_on_channels
3976 to not to send the client provided as argument. Affected file
3977 silcd/packet_send.[ch].
3979 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Implemented OPER and SILCOPER commands into the server and
3984 * Added silc_auth_verify and silc_auth_verify_data to verify
3985 the authentication directly from the authentication payload.
3986 It supports verifying both passphrase and public key based
3987 authentication. Affected file lib/silccore/silcauth.[ch].
3989 * Added `hash' field to the SilcIDListData structure. It is the
3990 hash negotiated in the SKE protocol. Affected file is
3993 * Slight redesigning of the SilcAuthPayload handling routines.
3994 Do not send SilcPKCS but SilcPublicKey as argument.
3996 * Implemented the public key authentication support to the
3997 serverconfig. The public key is loaded from the provided path
3998 and saved as authentication data to void * pointer. Thus,
3999 changed the unsigned char *auth_data to void *auth_data;
4001 * Fixed SHUTDOWN command to send the reply before the server
4002 is shutdown. :) Affected file silcd/command.c.
4004 * Fixed fatal bug in CONNECT command. The hostname was invalid
4005 memory and server crashed. Affected file silcd/command.c.
4007 * Fixed fatal bug in CLOSE command. The server_entry became
4008 invalid but was referenced later in the command. Affected file
4011 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Fixed fatal bug in failure packet handling. Server ignored
4014 the failure and thus crashed when it came.
4018 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4021 that the command may be executed only once in (about) 2 seconds.
4022 The old SILC_CF_LAG flag is same but allows command bursts up
4023 to five before limiting.
4025 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4026 server code. Various commands now includes the CF_LAG_STRICT
4027 flag to disallow any kind of miss-use of the command.
4029 * Fixed the silc_buffer_unformat to not to allocate any data
4030 if the length of the data is zero. It used to allocate the
4031 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4033 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Changed the format of AdminConnection configuration section
4036 in the server. Added username of the admin to the format.
4037 Affected files silcd/serverconfig.[ch].
4039 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4040 to return admin configuration data by host, username and/or
4043 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Implemented WHOWAS command to the server. Added the functions:
4047 silc_server_command_whowas_parse,
4048 silc_server_command_whowas_send_reply,
4049 silc_server_command_whowas_from_client and
4050 silc_server_command_whowas_from_server
4052 * Added <Client ID> argument to the WHOWAS command reply. Updated
4053 the protocol specs accordingly.
4055 * Implemented WHOWAS command and command_reply to the client
4058 Implemented the WHOWAS printing on the user interface.
4060 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Added new argument to the WHOWAS command reply, the real name.
4063 It is an optional argument. Updated the protocol specs.
4065 * Added SilcIDCacheDestructor callback that is registered when
4066 the SilcIDCache is allocated. The callback is called when
4067 an cache entry in the ID Cache expires, or is purged from the
4068 cache. Added into lib/silccore/idcache.[ch].
4070 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4071 to destruct the client entries when the cache entry expires.
4072 Other ID Cache's in server and in the client library ignores
4075 * If the ID Cache entry's `expire' field is zero then the entry
4076 never expires. Added boolean `expire' argument to the
4077 silc_idcache_add function in the lib/silccore/idcache.[ch].
4078 If it is TRUE the default expiry value is used.
4080 * Added silc_server_free_client_data_timeout that is registered
4081 when client disconnects. By default for 5 minutes we preserve
4082 the client entry for history - for WHOWAS command.
4084 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Added support to the server to enforce that commands are not
4087 executed more than once in 2 seconds. If server receives
4088 commands from client more frequently, timeout is registered
4089 to process the commands. Affected file silcd/command.c.
4090 Added new function silc_server_command_process_timeout.
4092 * Changed NICK_NOTIFY handling in client library to check that
4093 if the client's nickname was changed, so there is no need to
4094 resolve anything from the server.
4096 * Removed error printing from the WHOIS and IDENTIFY commands.
4097 If error occurs then it is ignored silently in the client library.
4098 The application, however, may map the received error to
4099 human readable error string. The application currently maps
4100 the NO_SUCH_NICKNAME error to string.
4102 * Made the command status message public to the application. Moved
4103 them from lib/silcclient/command_reply.c to
4104 lib/silcclient/command_reply.h. The application can map the
4105 received command status to the string with the
4106 silc_client_command_status_message function.
4108 * Added check to the server to check that client's ID is same
4109 as the Source ID in the packet the client sent. They must
4112 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Added dist-bzip hook to the Makefile.am to make bzip2
4115 compressed distributions.
4117 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Server now enforces the maximum length for the nickname and
4120 the channel as protocol specification dictates. 128 bytes for
4121 nickname and 256 bytes for channel name.
4123 * Moved the WHOIS printing to the application. The client libary
4124 does not print out the WHOIS information anymore, the application
4125 must do it. Renamed silc_client_command_reply_whois_print to
4126 the silc_client_command_reply_whois_save.
4128 The client's idle time is also sent to the application now, and
4129 the idle is shown on screen.
4131 * Added silc_client_command_reply_identify_save to save the
4132 received IDENTIFY entries.
4134 * Do not check for channel private keys in message sending and
4135 reception if the channel does not have the PRIVKEY mode set.
4136 Affected file lib/silclient/client_channel.c.
4138 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4141 just surfaced after chaning the JOIN procedure.
4143 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Added silc_client_get_clients_by_list to get client entries
4146 from Client ID list, that is returned for example by JOIN
4147 and USERS command replies. The application should use this
4148 function for example when JOIN command reply is received to
4149 resolve the clients already on the channel (library does not
4150 do that anymore as USERS command reply is not used in the JOIN
4151 procedure anymore). Affected files lib/silcclient/silcapi.h and
4152 lib/silcclient/idlist.c.
4154 * JOIN command reply and USERS command reply returns now SilcBuffer
4155 pointers instead of unsigned char pointers when returning
4156 the client list and mode list.
4158 * Added <Client ID> argument to the JOIN command reply, mainly
4159 for the server to identify for which client the command was
4160 originally sent. Updated protocol specs accordingly.
4162 * Added SilcDlist private_key pointer to the SilcChannelEntry
4163 in the client to support the channel private keys. Affected
4164 file is lib/silcclient/idlist.h.
4166 * Added SilcChannelPrivateKey argument to the function
4167 silc_client_send_channel_message so that application can choose
4168 to use specific private ke if it wants to. If it is not provided,
4169 the normal channel key is used, unless private keys are set.
4170 In this case the first (key that was added first) is used
4171 as the encryption key.
4173 * Implemented the support for channel private key handling.
4174 Implemented the following functions:
4176 silc_client_add_channel_private_key,
4177 silc_client_del_channel_private_keys,
4178 silc_client_del_channel_private_key,
4179 silc_client_list_channel_private_keys and
4180 silc_client_free_channel_private_keys
4182 Affected file lib/silcclient/client_channel.c.
4184 * Added the support for the private keys in the channel message
4185 sending and encryption and in the message reception and
4186 decryption. Affected funtions are
4187 silc_client_send_channel_message and silc_client_channel_message.
4189 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Added SKE's key verify callback to the client library's
4192 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4194 * Removed the statement that server (or router) must send USERS
4195 command reply when joining to the channel so that the client
4196 knows who are on the channel. Instead, the client list and
4197 client's mode list is now sent in the JOIN command reply to the
4198 client who joined channel. This is better solution.
4200 * Added function silc_server_get_users_on_channel and function
4201 silc_server_save_users_on_channel to the silcd/server.[ch].
4203 * Removed function silc_server_command_send_users from the
4206 * Do not show topic on the client library anymore. The topic is
4207 sent in the command reply notify to the application and the
4208 application must show the topic now.
4210 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Added client searching by nickname hash into the IDENTIFY and
4213 WHOIS commands in the server as they were clearly missing from
4214 them. Affected file is silcd/command.c.
4216 * Fixed a bug in private message receiving in the client library.
4217 The remote ID was freed and it wasn't supposed, now it is
4220 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Minor fix to the channel payload; allocate the data area, as it
4223 needs to be of specific length.
4225 * If the key agreement port is zero then the operating
4226 system will define the bound port. Affected files are
4227 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4229 * Added new function silc_channel_payload_decrypt into the file
4230 lib/silccore/silcchannel.[ch].
4232 * Moved the channel message etc, check from silc_packet_decrypt
4233 to applications. The library calls now a generic
4234 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4235 when the packet is either normal or special. This was done to
4236 allow more wide range of checking that was not allowed when
4237 the code was in library. Now applications can do virtually any
4238 checks to the packet and return to the library the decision how
4239 the packet should be processed. Affected files are
4240 lib/silccore/silcpacket.[ch].
4242 Added silc_server_packet_decrypt_check to the server and
4243 silc_client_packet_decrypt_check to the client library.
4245 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4246 to send with specified source and destination information.
4248 * Channel message delivery between routers was broken after the
4249 channel key distribution was fixed earlier. The channel key
4250 was used be to distributed to other routers as well which is not
4251 allowed by the protocol. Now this is fixed and channel keys
4252 really are cell specific and the channel message delivery between
4253 routers comply with the protocol specification.
4255 * Fixed various commands in server to check also the global list
4256 for the channel entry and not just the local list. The affected
4257 file silcd/command.c.
4259 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Added assert()s to buffer formatting and unformatting routines
4262 to assert (if --enable-debug) when error occurs. Affected
4263 file: lib/silcutil/silcbuffmt.c.
4265 * Changed to auto-reconnect to check whether the remote host is
4266 router and register the re-connect timeout if it is. It used
4267 to check that whether we are normal server, but router must do
4268 auto-reconnect with another router as well. Affected file
4271 * Removed the [<key len>] option from CMODE command as the cipher
4272 name decides the key length, nowadays. See the defined ciphers
4273 from the protocol specification.
4275 * Added [<hmac>] option to the CMODE command to define the HMAC
4276 for the channel. Added SILC_CMODE_HMAC channel mode.
4278 * Added [<hmac>] option for the JOIN command so that user can
4279 select which HMAC is used to compute the MACs of the channel
4282 * Added Hmac field to the Channel Message Payload. The integrity
4283 of plaintext channel messages are now protected by computing
4284 MAC of the message and attaching the MAC to the payload. The
4285 MAC is encrypted. Now, it is clear that this causes some
4286 overhead to the size of the packet but rationale for this is that
4287 now the receiver can verify whether the channel message decrypted
4288 correctly and also when private keys are set for the channel the
4289 receiver can decrypt the packet with several keys and check from
4290 the MAC which key decrypted the message correctly.
4292 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4293 lib/silccrypt/silccipher.[ch].
4295 * Added silc_hash_len to return the digest length into the
4296 lib/silcrypt/silchash.[ch].
4298 * Rewrote parts of Silc Channel Payload interface in the
4299 lib/silccore/silcchannel.[ch]. The encode function now also
4300 encrypts the packet and parse function decrypts it.
4302 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Fixed a minor formatting bug in the SKE's key material processing.
4305 It actually might have processed the keys wrong way resulting
4308 * Redefined the mandatory HMAC algorithms and added new algorithms.
4309 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4310 and hmac-md5 truncated to 96 bits. The mandatory is now
4311 hmac-sha1-96. Rest are optional (including the one that used
4312 to be mandatory). Rationale for this is that the truncated HMAC
4313 length is sufficient from security point of view and can actually
4314 make the attack against the HMAC harder. Also, the truncated
4315 HMAC causes less overhead to the packets. See the RFC2104 for
4318 * Added new [hmac] configuration section. The SKE used to use
4319 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4320 is of course wrong. The official names that must be proposed in
4321 the SKE are the ones defined in the protocol specification
4322 (hmac-sha1-96 for example). The user can configure any hmac
4323 using any hash function configured in the [hash] section. At
4324 least, the mandatory must be configured.
4326 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4328 * Added HMAC list to the SKE proposal list. It has now both
4329 hash algorithm list and HMAC list. This makes the protocol
4330 incompatible with previous versions. The SKE now seems to work
4331 the way it is supposed to work, for the first time actually.
4333 * Defined plain Hash algorithms to the protocol specification.
4336 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Implemented support for key agreement packets into the server.
4339 Added functions silc_server_key_agreement and
4340 silc_server_send_key_agreement. Other than these functions,
4341 server has nothing to do with this packet.
4343 * Added support for private message key packets into the server.
4344 Added functions silc_server_private_message_key and
4345 silc_server_send_private_message_key.
4349 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4350 called in the protocol's final callback instead in the END
4351 protocol state. This makes a little more sense and in the same
4352 time in client we can use the same protocol routines for normal
4353 key exchange and to key agreement packet handling as well.
4355 * Added to both client's and server's KE protocol context the
4356 SilcSKEKeyMaterial pointer to save the key material. We will
4357 bring the key material to the protocol's final callback by doing
4358 this. The final callback must free the key material.
4360 * Added SKE's packet_send callback into client's KE protocol
4361 context so that the caller can choose what packet sending function
4362 is used. This way we can use different packet sending when
4363 doing normal SKE when doing key agreement packet handling (in
4364 the key agreement packet handling we do not want to encrypt
4367 * Implemented the responder side of the key agreement routines
4368 in the client. The client can now bind to specified port and
4369 accept incoming key negotiation. The key material is passed
4370 to the application after the protocol is over.
4372 * Implemented the processing of incoming Key Agreement packet
4373 in the client. Added function silc_client_key_agreement to
4376 * Implemented the intiator side of the key agreement routines
4377 in the client. The client can now initiate key agreement with
4378 another remote client. The key material is passed to the
4379 application after the protocol is over.
4381 * Created client_keyagr.c to include all the key agreement
4384 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4385 SILC_TASK_CALLBACK except that it is not static.
4387 * Created client_notify.c and moved the Notify packet handling
4388 from the client.[ch] into that file.
4390 * Created client_prvmsg.c and moved all private message and
4391 private message key routines from the client.[ch] into that file.
4393 * Create client_channel.c and moved all channel message and
4394 channel private key routines from the client.[ch] into that file.
4396 * Changed silc_client_get_client_by_id_resolve to resolve with
4397 WHOIS command instead of IDENTIFY command, in the file
4398 lib/silclient/idlist.c.
4400 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Implemented the SKE's responder side to the Client library.
4404 * When FAILURE is received to the protocol do not trust it
4405 blindly. Register a timeout to wait whether the remote closes
4406 the connection as it should do it, only after that process the
4407 actual failure. This was changed to both client and server.
4409 * Added client_internal.h to include some of the structures
4410 there instead of client.h in lib/silcclient/.
4412 * Added function silc_task_unregister_by_callback to unregister
4413 timeouts by the callback function.
4415 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Some "Incomplete WHOIS info" errors has been appearing on the
4418 log files. Took away the entry->userinfo check from WHOIS
4419 reply sending. The entry->userinfo is now " " if client did not
4420 provide one. I thought this was fixed earlier but something
4421 is wrong still. Let's see if the error still appears.
4423 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Fixed a minor bug in the login when the channel key is
4426 re-generated in the server. It used to generate the key in
4427 wrong order and thus caused problems in the channel traffic.
4429 * Fixed a minor bug in channel key distsribution after
4430 KICK command. The key was not sent to the router even though
4433 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Added silc_ske_process_key_material_data as generic routine
4436 to process any key material as the SILC protocol dictates. The
4437 function is used by the actual SKE library but can be used by
4438 applications as well. This relates to the private message keys
4439 and the channel private keys since they must be processed the
4440 same way the normal SILC session keys. The protocol dictates
4441 this. Affected files: lib/silcske/silcske.[ch].
4443 Added also silc_ske_free_key_material to free the
4444 SilcSKEKeyMaterial structure.
4446 * Defined silc_cipher_set_key function to set the key for
4447 cipher without using the object's method function. The affected
4448 files: lib/silccrypt/silccipher.[ch].
4450 * Implemented silc silc_client_add_private_message_key,
4451 silc_client_add_private_message_key_ske,
4452 silc_client_del_private_message_key,
4453 silc_client_list_private_message_keys and
4454 silc_client_free_private_message_keys functions in the
4457 Added functions silc_client_send_private_message_key to send
4458 the Private Message Key payload and silc_client_private_message_key
4459 to handle incoming Private Message Key payload.
4461 * Added Cipher field to the Private Message Key payload to set
4462 the cipher to be used. If ignored, the default cipher defined
4463 in the SILC protocol (aes-256-cbc) is used.
4465 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Removed lib/silcclient/ops.h file.
4469 Redefined parts of the SILC Client Library API. Created new
4470 file silcapi.h that deprecates the ops.h file and defines the
4471 published Client Library API. Defined also private message key
4472 API and channel private key API into the file.
4474 This is the file that the application must include from the
4475 SILC Client Library. Other files need not be included by
4476 the application anymore.
4478 * Added new key_agreement client operation callback and also
4479 defined the Key Agreement library API for the application.
4481 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4484 is used by clients to request key negotiation between another
4485 client in the SILC network. If the negotiation is started it
4486 is performed using the SKE protocol. The result of the
4487 negotiation, the secret key material, can be used for example
4488 as private message key.
4490 Implemented the Key Agreement payload into the files
4491 lib/silccore/silauth.[ch].
4493 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Redefined ciphers for the SILC protocol. Added some new ciphers
4496 and defined the key lengths for the algorithms. Changed the
4497 code accordingly. The default key length is now 256 bits.
4499 * Fixed SKE key distribution function silc_ske_process_key_material
4500 when the key length is more than 128 bits. The default key
4501 length in SILC is now 256 bits.
4503 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4504 to indicate unsupported algorithm.
4506 * Renamed rijndael.c to aes.c and all functions as well.
4508 * Fixed a long standing channel key setting bug in client library.
4509 Weird that it has never surfaced before.
4511 * Fixed bug in channel deletion. If the entire channel is removed
4512 then it must also delete the references of the channel entry
4513 from the client's channel list as the client's channel entry and
4514 the channel's client entry share same memory.
4516 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Implemented CONNECT and SHUTDOWN commands in the client.
4520 * Implemented CLOSE command to the client.
4522 * Added the function silc_idlist_find_server_by_name into the
4523 files silcd/idlist.[ch].
4525 Added the function silc_idlist_find_server_by_conn into the
4526 files silcd/idlist.[ch].
4528 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * DIE command was renamed to SHUTDOWN. Updated the both code
4533 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4534 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4536 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4539 * Added function silc_server_create_connection function to create
4540 connection to remote router. My server implementation actually
4541 does not allow router to connect to normal server (it expects
4542 that normal server always initiates the connection to the router)
4543 so the CONNECT command is only good for connecting to another
4546 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4549 or some other client was kicked from the channel.
4551 Implemented the handling of the notify type to both client
4554 Implemented silc_server_send_notify_kicked to send the KICKED
4555 notify. It is used to send it to the server's primary router.
4557 * Implemented the KICK command into server and client.
4559 * Added `query' argument to the silc_idlist_get_client function
4560 to indicate whether to query the client from server or not if
4563 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4564 to indicate that the client is not channel founder.
4568 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Removed the rng context from SilcPacketContext structure and
4571 changed that the packet routine uses the Global RNG API.
4573 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added support for quit message that client can "leave" on the
4576 channel when it quits the SILC. It is ditributed inside the
4577 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4579 Added silc_server_free_client_data that will take the
4580 signoff message as argument.
4582 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4584 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Updated parts of the protocol specification to keep it up
4589 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4592 payloads in one packet.
4594 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4595 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4596 use now the new List flag.
4598 * Also deprecated the following packet types: REPLACE_ID,
4599 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4601 * Added list support for Notify packet in server.
4603 * Added silc_server_send_notify_channel_change to send the
4604 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4605 the silc_server_send_replace_id.
4607 * Added silc_server_send_notify_nick_change to send the
4608 NICK_CHANGE notify type. Deprecates the function
4609 silc_server_send_replace_id.
4611 * Added silc_server_send_notify_join to send the JOIN notify type.
4612 Deprecates the function silc_server_send_new_channel_user.
4614 * Added silc_server_send_notify_leave to send LEAVE notify type.
4615 Deprecates the function silc_server_send_remove_channel_user.
4617 * Added silc_server_send_notify_cmode and
4618 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4619 types. Deprecates the silc_server_send_set_mode function.
4621 * Added SERVER_SIGNOFF notify type to indicate that server has
4622 quit. This means that all clients on the channel from that
4623 server will drop. This can be also used when netsplit happens.
4625 Deprecated REMOVE_ID packet type since it is not needed anymore
4628 Added silc_server_send_notify_server_signoff to send the
4629 SERVER_SIGNOFF notify type. Deprecates the function
4630 silc_server_send_remove_id.
4632 Added also silc_server_send_notify_signoff to send the
4633 SIGNOFF notify type.
4635 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4636 SILC protocol from this day on. Changed the protocol
4637 specification as well.
4639 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4640 notify type. It is used between routers to notify about
4641 topic changes on a channel.
4643 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4646 * Partly updated the protocol specification to comply with the
4647 changes now made. It is still though a bit outdated.
4649 * The JOIN notify type now takes one extra argument <Channel ID>.
4650 The packet used to be destined to the channel but now the
4651 JOIN type may be sent as list thus it is impossible to
4652 destine it to any specific channel. By adding this argument
4653 it is again possible.
4655 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added CREDITS file. The CHANGES and CREDITS file will appear
4658 in the distribution as well.
4660 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4663 types in the server's silcd/packet_receive.c.
4665 * Implemented CMODE and CUMODE to work in router environment.
4667 * Fixed minor encoding and decoding buglet from the
4668 lib/silccore/silcmode.c.
4670 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4673 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4675 * Changed all SilcConfigServer* and silc_config_server* to
4676 SilcServerConfig* and silc_server_config*, respectively.
4679 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Associated the ID (client or server ID) to the Authentication
4682 Payload to avoid any possibility of forging. Updated the
4683 protocol specification and the code accordingly.
4685 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * The RSA key length is now save to the RsaKey context in the
4688 key generation process in lib/silccrypt/rsa.c. The key length
4689 is now used to figure out the maximum size of the block allowed
4690 to be encrypted/signed.
4692 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4693 is equivalent to the silc_mp_mp2bin but does not allocate any
4696 * Changed silc_mp_mp2bin API to take length argument. If it is
4697 non-zero then the buffer is allocated that large. If zero, then
4698 the size is approximated using silc_mp_sizeinbase, which however
4701 * Created Global RNG API which is global RNG that application can
4702 initialize. After initializing, any routine anywhere in the
4703 code (including library) can use RNG without allocating a new
4704 RNG object. This was done to allow this sort of use of the
4705 RNG in code that has no chance to allocate RNG object. All
4706 applications currently allocate this and many routines in the
4707 library use this. Affected file lib/silccrypt/silcrng.[ch].
4709 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4710 it to use the Global RNG API.
4712 * Defined Authentication Payload into protocol specification that
4713 is used during SILC session to authenticate entities. It is
4714 used for example by client to authenticate itself to the server
4715 to obtain server operator privileges.
4717 Implemented this payload into the lib/silccore/silcauth.[ch].
4718 Implemented also routines for public key based authentication
4719 as the new protocol specification dictates.
4721 Moved definitions of different authentication methods from
4722 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4724 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4725 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4726 silc_pkcs_verify_with_hash functions into the file
4727 lib/silccrypt/silcpkcs.[ch].
4729 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * The client entry's userinfo pointer must be always valid.
4732 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4733 will fail since it requires the userinfo. Now, the userinfo
4734 is allocated as "" if actual userinfo does not exist. Actually,
4735 it must exist and it is totally Ok to drop client connections
4736 that does not announce the userinfo. However, we will make
4737 this workaround for now.
4739 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4740 to return the remote port by socket.
4742 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4745 SILC_SERVER_PENDING_EXEC and added an new macro
4746 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4747 data or when error occurs while processing the pending command.
4749 Added new argument `destructor' into silc_server_command_pending
4750 and to the SilcServerCommandPending object. This destructor is
4751 now called after calling the pending callback or if error occurs
4752 immediately. If error occurs the actual pending callback won't
4753 be called at all - only the destructor. The destructor may be
4754 NULL if destructor is not needed.
4756 All this applies for client library code as well. Similar
4757 changes were made there as well for the pending commands.
4759 In the client, the application must now allocate the
4760 SilcClientCommandContext with the silc_client_command_alloc
4763 * Added reference counter to the SilcServerCommandContext. Added
4764 function silc_server_command_alloc and silc_server_command_dup
4767 Same type of functions added to the client library for the same
4770 * Removed the cmd_ident from IDListData away since it is now
4771 global for all connections. It is the command identifier used
4772 in command sending and with pending commands. The affected file
4775 * Added reference counter to the SilcSocketConnection objecet to
4776 indicate the usage count of the object. The object won't be
4777 freed untill the reference counter hits zero. Currently only
4778 server uses this, and client ignores it. The client must be
4779 set to use this too later. The affected files are
4780 lib/silccore/silcsockconn.[ch]. Added also the function
4781 silc_socket_dup to increase the reference counter.
4783 This was mainly added because it is possible that the socket
4784 is removed underneath of pending command or other async
4785 operation. Now it won't be free'd and proper DISCONNECTING
4786 flags, etc. can be set to avoid sending data to connection that
4787 is not valid anymore.
4789 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4790 the connection. After that it sets SILC_SET_DISCONNECTED.
4791 It is, however, possible that the socket data is not still freed.
4792 The silc_server_packet_process now checks that data is not
4793 read or written to connection that is DISCONNECTED. The socket
4794 get's freed when the reference counter hits zero.
4796 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Changed the client operation API: channel_message operation's
4799 `sender' is now the client entry of the sender, not the nickname
4800 and the `channel' is the channel entry, not the channel name.
4802 In the private_message operation the `sender' is now also the
4803 client entry of the sender not the nickname.
4805 Affected file is lib/silcclient/ops.h and all applications
4806 using the client operations.
4808 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Moved the calling of ops->connect() from connect_to_server_final
4811 into receive_new_id functin since that is the point when the
4812 client is actually allowed to send traffic to network. The
4813 affected file is lib/silcclient/client.c.
4815 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4818 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4819 (if needs broadcasting) instead of broadcasting the packets one
4820 by one which would make a burst in the network traffic.
4822 * Added `broadcast' argument to the functions in silcd/server.[ch]
4823 silc_server_create_new_channel[_with_id] to indicate whether
4824 to send New Channel packet to primary router.
4826 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added new function into the silcd/server.[ch] files:
4829 silc_server_create_new_channel_with_id to create new channel with
4830 already existing Channel ID.
4832 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4833 lib/silccore/silcpacket.h. This packet is used t send list of
4834 Set Mode payloads inside one packet. Server uses this to set
4835 the modes for the channels and clients on those channels, that it
4836 announced to the router when it connected to it. The protocol
4837 specification has been updated accordingly.
4839 * The silc_server_new_channel did not handle the packet coming
4840 from normal server as it normally does not send that. However,
4841 when it announces its channels it does send it. Implemented
4842 the support for that.
4844 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4845 into the file lib/silccore/id.h.
4847 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4849 * Fixed memory leaks in the functions silc_idlist_del_client,
4850 silc_idlist_del_channel and silc_idlist_del_server in the file
4851 silcd/idlist.c. All of those leaked like a sieve.
4853 * Fixed some small memory leaks in the client's function
4854 silc_client_notify_by_server.
4856 * Added functions into silcd/server.c: silc_server_announce_clients,
4857 silc_server_announce_channels and silc_server_announce_server.
4858 These functions are used by normal and router server to announce
4859 to its primary router about clients, channels and servers (when
4860 router) that we own. This is done after we've connected to the
4863 These functions effectively implements the following packet types:
4864 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4865 and SILC_PACKET_NEW_ID_LIST.
4867 * Added new functions into the silcd/packet_receive.[ch]:
4868 silc_server_new_id_list, silc_server_new_channel_list and
4869 silc_server_new_channel_user_list to handle the incoming
4870 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4872 * Added support of changing Channel ID in the function
4873 silc_server_replace_id. If the server that announces a channel
4874 to the router already exists in the router (with same name but
4875 with different Channel ID), router is responsible to send
4876 Replace ID packet to the server and force the server to change
4877 the Channel ID to the one router has.
4879 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4880 client that the Channel ID has been changed by the router. The
4881 normal server sends this to the client. Client must start using
4882 the new Channel ID as the channel's ID.
4884 Implemented handling of this new type into lib/silcclient/client.c
4885 into the function silc_client_notify_by_server.
4887 * Added new function silc_idlist_replace_channel_id into the files
4888 silcd/idlist.[ch] to replace the Channel ID.
4890 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Call silc_server_command_identify_check always when processing
4893 the IDENTIFY command in silcd/command.c
4895 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4898 send keepalive packets. The packet can be sent by clients,
4899 servers and routers.
4901 Added function silc_socket_set_heartbeat into the file
4902 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4903 If not set, the heartbeat is not performed. The actual
4904 heartbeat is implemented in the low level socket connection
4905 library. However, application is responsible of actually
4908 Added silc_server_send_heartbeat to send the actual heartbeat
4909 packet into silcd/packet_send.[ch]. Server now performs
4910 keepalive with all connections.
4912 * Added silc_task_get_first function into lib/silcutil/silctask.c
4913 to return the timeout task with shortest timeout. There was a bug
4914 in task unregistration that caused problems. TODO has been
4915 updated to include that task system must be rewritten.
4917 * The client library will now resolve the client information when
4918 receiving JOIN notify from server for client that we know but
4919 have incomplete information.
4921 * Rewrote parts of silc_server_remove_from_channels and
4922 silc_server_remove_from_one_channel as they did not remove the
4923 channel in some circumstances even though they should've.
4925 * Encryption problem encountered in server:
4927 The LEAVE command used to send the Channel Key packet to the
4928 router immediately after generating it. However, the code
4929 had earlier sent Remove Channel user packet but not immediately,
4930 ie. it was put to queue. The order of packets in the router
4931 was that Channel Key packet was first and Remove Channel User
4932 packet was second, even though they were encrypted in the
4933 reverse order. For this reason, MAC check failed. Now, this
4934 is fixed by not sending the Channel Key packet immediately but
4935 putting it to queue. However, this is more fundamental problem:
4936 packets that are in queue should actually not be encrypted
4937 because packets that are sent immediately gets encrypted
4938 actually with wrong IV (and thus MAC check fails). So, packets
4939 that are in queue should be encrypted when they are sent to
4940 the wire and not when they put to the queue.
4942 However, the problem is that the current system has not been
4943 designed to work that way. Instead, the packet is encrypted
4944 as soon as possible and left to the queue. The queue is then
4945 just purged into wire. There won't be any fixes for this
4946 any time soon. So, the current semantic for packet sending
4949 o If you send packet to remote host and do not force the send
4950 (the packet will be in queue) then all subsequent packets to the
4951 same remote host must also be put to the queue. Only after the
4952 queue has been purged is it safe again to force the packet
4955 o If you send all packets immediately then it safe to send
4956 any of subsequent packets through the queue, however, after
4957 the first packet is put to queue then any subsequent packets
4958 must also be put to the queue.
4960 Follow these rules and everything works fine.
4962 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Added new function silc_server_remove_clients_by_server to
4965 remove all client entries from ID list when the server connection
4966 is lost. In this case it is also important to invalidate all
4967 client entires as they hold the invalid server entry. This
4968 fixes fatal bug when server has lost connection and will reconnect
4971 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Made some sanity checks to silc_server_daemonise like to check
4974 whether the requested user and group actually exists.
4976 * Added sanity check to SKE's silc_ske_responder_finish to check
4977 that the public and private key actually is valid.
4979 * Invalidate the client's nickname when receiving Replace ID
4980 packet and the Client ID is being replaced. This means that the
4981 server will query the nickname if someone needs it (client)
4984 * Sort the ID Cache in client library when the ID Cache data
4985 has changed (needs sorting).
4987 * Do not allow for SILC client to create several connections to
4988 several servers. The client does not support windows right now
4989 and generating multiple connections causes weird behaviour.
4991 Irssi-silc client does support windows and can handle several
4992 connections without problems, see: www.irssi.org and SILC plugin.
4994 * Fixed some places where client was added to the IDList. The
4995 rule of thumb is following (in order to get everything right):
4996 If the client is directly connected local client then the
4997 `connection' argument must be set and `router' argument must be
4998 NULL to silc_idlist_add_client function. If the client is not
4999 directly connected client then the `router' argument must
5000 bet set and the `connection' argument must be NULL to the
5001 silc_idlist_add_client function.
5003 * The funtion silc_server_packet_send_local_channel actually did
5004 not check whether the client was locally connected or not. It
5005 does that now. Fixed a bug related to LEAVE command.
5007 * Fixed Remove Channel User payload parsing bug in server's
5008 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5010 * The server's silc_server_save_channel_key now checks also the
5011 global ID list for the channel as it might not be in the local
5012 list. Fixed a bug related to LEAVE command.
5014 * Is this the end of the [<unknown>] buglet that has been lurking
5015 around for a long time? A little for loop fix in server's
5016 silc_server_command_whois_parse that is used by both IDENTIFY
5017 and WHOIS command. At least, this was a clear bug and a cause
5018 of one type of [<unknown>] buglet.
5020 * WHOIS and IDENTIFY commands call the function
5021 silc_server_command_[whois/identify]_check function even if
5022 we are not router server.
5024 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Added --with-gmp configuration option. If set the GMP
5027 is always compiled in the SILC source tree. If not set then
5028 it is checked whether the system has the GMP3 installed. If
5029 it has then the GMP won't be compiled (the system's headers
5030 and library is used), if it doesn't have it then the GMP is
5031 compiled in the SILC source tree.
5033 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Changed RSA private exponent generation to what PKCS #1
5036 suggests. We try to find the smallest possible d by doing
5037 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5038 not security fix but optimization.
5040 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added new config entry [Identity] to fork the server and run
5043 it as specific user and group. A patch from Bostik.
5045 * Imported Dotconf configuration library into lib/dotconf.
5046 This will be used to create the SILC configuration files later.
5047 It will appear in the distsribution after this commit.
5049 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * A big code auditing weekend happening. Auditing code for
5052 obvious mistakes, bugs and errors. Also, removing any code
5055 Removed files for being obsolete:
5057 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5058 inline in the file lib/silcutil/silcbuffer.h)
5060 o lib/silcutil/silcbufutil.c (the header has inline versions)
5062 Changed code to fix possible error conditions:
5064 o The buffer formatting routines now check that the destination
5065 buffer really has enough space to add the data. This applies for
5066 both buffer formatting and unformatting
5067 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5068 unformatting was changed to accomodate following rules:
5069 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5070 sent to the function while XXX_*STRING will not allocate or copy
5071 the data into the buffer. Instead it sets the pointer from the
5072 buffer into the pointer sent as argument (XXX_*STRING used to
5073 require that the pointer must be allocated already). This change
5074 makes this whole thing a bit more consistent and more optimized
5075 (note that the data returned in the unformatting with XXX_*STRING
5076 must not be freed now). The routines return now -1 on error.
5078 o Tried to find all code that use buffer_format and buffer_unformat
5079 and added return value checking to prevent formatting and
5080 especially unformatting errors and possible subsequent fatal
5083 o Changed ske->x and ske->KEY to mallocated pointers in
5084 lib/silcske/silcske.h. Fixed possible data and memory leak.
5086 o Added return value checking to all *_parse* functions. Fixed
5087 many memory leaks as well.
5089 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5090 so that buffer overflows would not happen. All code now also
5091 checks the return value as it can fail.
5093 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Added reconnection support to server if the normal server looses
5096 its connection to the router (for example if router is rebooted).
5097 The server performs normal reconnection strategy implemented
5098 to the server. Affected file silcd/server.c.
5100 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Added new packet type SILC_PACKET_SET_MODE that is used to
5103 distribute the information about changed modes (for clients,
5104 channels and clients channel modes) to all routers in the
5105 network. Updated the protocol specification accordingly.
5107 Added functions into silcd/packet_send.c and
5108 silcd/packet_receive.c: silc_server_send_set_mode,
5109 silc_server_set_mode.
5111 Added new files silcmode.[ch] into lib/silccore that implements
5112 the encoding and decoding of Set Mode Payload. Added new type
5113 SilcSetModePayload. Moved the definitions of different modes
5114 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5116 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Oops, a little mistake in server's connection authentication
5119 protocol. The protocol is not ended with FAILURE but with
5120 SUCCESS if the authentication is Ok. :) Affected file is
5123 * Implemented NICK_CHANGE notify handling in server in the file
5124 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5125 the local clients on the channel. After the changing nickname
5126 in router environment snhould work and the [<unknown>] nickname
5127 should appear no more.
5129 The silc_server_replace_id function that receives the Replace ID
5130 payload now sends the NICK_CHANGE notify type also in the file
5131 silcd/packet_receive.c
5133 * Changed WHOIS and IDENTIFY command to support the maximum amount
5134 of arguments defined in protocol specs (3328 arguments). This
5135 fixed a bug that caused problems when there were more than three
5138 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Added extra parameter, command identifier, to the
5141 silc_client_send_command so that explicit command identifier
5144 Changed that ID list routines uses specific command identifier
5145 when sending WHOIS/IDENTIFY requests to the server so that they
5146 can be identified when the reply comes back.
5148 Affected files lib/silcclient/command.[ch],
5149 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5151 * Added `sender' argument to silc_server_packet_send_to_channel
5152 to indicaet the sender who originally sent the packet to us
5153 that we are now re-sending. Ignored if NULL. Affected file
5154 silcd/packet_send.[ch].
5156 * Added some server statistics support in silcd/server_internal.h
5157 SilcServerStatistics structure and around the server code. Also
5158 send some nice statistics information when client is connecting
5161 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Fixed channel ID decoding in server's JOIN command reply in
5164 silcd/command_reply.c
5166 * Fixed braodcasting of replace ID payload to not to send it if
5167 we are standalone server in silcd/packet_receive.c.
5169 * Fixed all channel message sending routines to not to send
5170 packets to clients that has router set, since they are routed
5171 separately in the same function earlier. Affects file
5172 silcd/packet_send.c and all channel packet sending functions.
5174 * In USERS reply, res_argv[i] are not allocated, the table
5175 is allocated. Thus changed that free the table, not its
5178 * In server's whois_check and identify_check if the client is
5179 locally connected do not send any WHOIS commands - they are not
5182 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Fixed some minor bugs in client when sending WHOIS command. The
5185 arguments was in wrong order.
5187 * Removed statis function add_to_channel from server in
5188 silcd/command.c that was previously used with the joining but
5191 * Tested USERS command in router environment successfully with two
5192 routers, two servers and two clients.
5194 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Reorganized the USERS command and command reply in client library
5197 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5198 When the command is given by user we register a pending command
5199 callback that will reprocess the command after the reply has been
5200 received from the server. When reprocessing the packet we then
5201 display the information. Thus, the USERS information is displayed
5202 now in the command callback instead of in the command reply
5203 callback. The processing of the command is same as previously
5204 when server has sent the command reply in the JOINing process.
5206 * Added to USERS command in silcd/command_reply.c to join the client,
5207 we didn't use to know about, to the channel after we've created
5208 a client entry for it. Also, for clienet we did know already still
5209 check whether it is on the channel or not and add it if not.
5211 * Removed silc_server_command_join_notify as the function and its
5214 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Changed the client's pending command handling to the same as the
5217 server's pending command handling. It is also now possible to
5218 execute command reply functions from other command reply
5219 function as the function callbacks for commands and command
5220 replies are one and same. The pending commands are not static
5221 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5222 in client connection context. Thus, pending commands are server
5223 connection specific as it is convenient.
5225 Changed the function silc_client_command_pending and
5226 silc_client_command_pending_del and added new function
5227 silc_client_command_pending_check. Removed the
5228 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5231 * Added cmd_ident, current command identifier, to the client
5232 connection context in lib/silcclient/client.h to keep track on
5233 command identifiers used in command sending. Client's command reply
5234 function handling now supports the mandatory command identifiers.
5236 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5237 funtions in client to fully support pending command callbacks.
5239 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5240 as one of the arguments to the application in the command reply
5243 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5244 before first releasing SILC but came back. Now it is removed again
5245 and should come back nomore. The FORWARDED flag was used only
5246 by the JOINing procedure by forwarding the command packet to router.
5247 Now, the JOINing procedure has been changed to more generic (due
5248 to various router environment issues) and FORWARDED is not needed
5249 anymore for anything. The protocol specification is yet to be
5252 Now, removed silc_server_packet_forward from server and the flag
5253 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5255 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Renamed NAMES command to USERS command. The NAMES was named that
5258 due to historical reasons. Now it is renamed. Also, rewrote
5259 parts of the USERS command. The nickname list is not sent anymore
5260 by the server. Only Client ID and mode lists are sent in the USERS
5261 command. Changed this also to the protocol specification.
5263 The client now resolves the names and stuff after it receives
5264 the USERS list from the server when joining to the channel.
5266 * WHOIS and IDENTIFY commands has been changed to support multiple
5267 Client ID's per command. One can now search for multiple users
5268 in the network by sending only one WHOIS or IDENTIFY command.
5269 Changed the code and the protocol specifications.
5271 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5272 uses silc_server_command_whois_parse to parse the request. */
5274 * If normal server, do not parse the WHOIS and IDENTIFY requests
5275 before sending it to the router. Saves some time.
5277 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5279 * Fixed JOIN command on client library. Wrong number of arguments
5280 used to crash the client.
5282 * Added silc_server_channel_has_global function to check whether
5283 channel has global users or not.
5285 * Added silc_server_channel_has_local function to check whether channel
5286 has locally connected clients on the channel.
5288 * The silc_server_remove_from_one_channel now checks whether the
5289 channel has global users or not after given client was removed from
5290 the channel. It also checks whether the channel has local clients
5291 on the channel anymore. If it does not have then the channel entry
5292 is removed as it is not needed anymore.
5294 * The silc_server_notify now checks on JOIN notify whether the joining
5295 client is one of locally connected or global. If it is global then
5296 the channel has now global users on the channel and that is marked
5297 to the channel entry. Also, it now saves the global client to
5298 global list who is joining and JOINs it to the channel. This is
5299 for normal server, that is.
5301 Changed silc_server_send_notify_on_channel,
5302 silc_server_packet_relay_to_channel and
5303 silc_server_packet_send_to_channel check if we are normal server
5304 and client has router set (ie. global client) do not send the
5305 message to that client, as it is already routed to our router.
5307 * Implemented LEAVE notify type handling in silc_server_notify
5310 * Tested LEAVE command in router environment successfully. Tested
5311 with two routers, two servers and two clients.
5315 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5317 * Implemented SIGNOFF notify type handling in silc_server_notify
5320 * silc_server_remove_id now removes the client entry from all channels
5321 it has joined and thusly sends SIGNOFF notify type.
5323 * Rewrote the NAMES list generation in server by removing two excess
5324 loops. The lists are created now inside one loop.
5326 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * silc_server_remove_channel_user checks now also global list
5329 for channel and client.
5331 * silc_server_new_channel_user checks now both local and global
5332 list for channel and client. Fixed a bug in client id decoding.
5333 Used to decode wrong buffer.
5335 * silc_server_channel_message checks now both local and global
5336 list for channel entry.
5338 * Tested channel joining (hence JOIN) in router environment
5339 successfully. Tested with two routers, two servers and two
5342 * Tested channel message sending in router environment successfully.
5344 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added silc_server_save_channel_key into server.[ch] to save the
5347 received channel key in Channel Key payload processing. It is
5348 also used in JOIN command reply handling.
5350 Equivalent function silc_client_save_channel_key added into
5351 client.[ch] into client library.
5353 * Changed JOIN command reply to send information whether the channel
5354 was created or not (is existing already) and the channel key
5355 payload. Changed protocol specs accordingly.
5357 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5358 the request was sent by ID and not by nickname. Crashed on
5361 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5364 now correctly save the received data.
5366 * silc_server_free_sock_user_data now notifies routers in the
5367 network about entities leaving the network.
5369 At the same time implemented functions silc_server_remove_id
5370 and silc_server_send_remove_id to receive and send REMOVE_ID
5371 packets. The packet is used to notify routers in the network
5372 about leaving entities. The ID removed will become invalid in
5375 * Added function silc_idlist_del_server into server. Removes and
5376 free's server entry from ID list.
5378 * silc_server_private_message function now checks, if we are router,
5379 that the destination ID really is valid ID, naturally.
5381 * In router when NEW_ID packet is received (for new client) the
5382 hash of the Client ID is saved in the ID Cache but the
5383 client->nickname is set to NULL, instead of putting the hash
5386 IDENTIFY command now also checks that client->nickname must be
5387 valid. If it is not if will request the data from the server who
5388 owns the client. Added new function
5389 silc_server_command_identify_check.
5391 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5392 to set the command to already allocated Command Payload.
5394 * Tested private message sending in router environment with two
5395 routers, two servers and two clients. Fixed minor bugs and now
5398 * Fixed segfault from client's NAMES command. Used to crash if
5401 * Forwarded packets must not be routed even if it is not destined
5402 to the receiver. Changed server code comply with this.
5404 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Added `require_reverse_mapping' boolean value to ServerParams
5407 structure. If TRUE (not default) the server will require that
5408 the connecting host has fully qualified domain name.
5410 If the reverse mapping is not required and hostname could not be
5411 found the IP address is used as hostname.
5413 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Implemented version string checking to both client and server.
5416 The check is incomplete currently due to the abnormal version
5417 strings used in development version of SILC.
5419 * Changed all command functions in server to use the new
5422 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Changed char *data to unsigned char *data in ID Cache system to
5425 support binary data as ID Cache data. Changed code to support
5426 binary data in lib/silccore/idcache.c.
5428 * Renamed silc_server_packet_relay_command_reply to
5429 silc_server_command_reply as it is normal packet receiving
5430 function. Rewrote the function to accept command replys for
5431 servers and not only for clients.
5433 * Mark remote router always as registered server if we are connecting
5434 to it. Otherwise, commands sent by the router to us are ignored.
5436 * All ID List find routines now returns the ID Cache Entry pointer
5437 as well if requested.
5439 * WHOIS command works now in router environment, tested with two
5440 routers, two servers and two clients.
5442 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5443 in router environment (as it is almost equivalent to WHOIS) but
5444 hasn't been tested thoroughly. Added new functions:
5446 silc_server_command_identify_parse
5447 silc_server_command_identify_send_reply
5448 silc_server_command_identify_from_client
5449 silc_server_command_identify_from_server
5451 * Disabled route cache adding because adding two different ID's with
5452 same IP replaces the old cache entry thus giving wrong route.
5453 The entry->router->connection is always the fastest route anyway
5454 so route cache may not be needed. Of course, new routes maybe
5455 established after receiving the ID when the entry->router->connection
5456 might not be anymore the most optimal.
5458 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Add route cache for received ID for fast routing.
5462 * Added silc_server_packet_route to route received packet on router
5463 that is not destined to us.
5465 * Renamed silc_server_get_route to silc_server_route_get.
5467 * Added id_string and id_string_len fields into SilcServer to
5468 include encoded ServerID for fast comparing without excess
5469 encoding of the ID's.
5471 * Cleaned up WHOIS command on server side. Added following static
5474 silc_server_command_whois_parse
5475 silc_server_command_whois_check
5476 silc_server_command_whois_send_reply
5477 silc_server_command_whois_from_client
5478 silc_server_command_whois_from_server
5480 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5481 arguments in command replies. All command functions should be
5482 updated to use this macro.
5484 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Minor typo fixes on command reply handling on server.
5488 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Added silc_server_command_add_to_channel internal routine to add
5491 the client to the channel after router has created the channel and
5492 sent command reply to the server.
5494 * Added generic silc_server_send_command to send any command from
5497 * Use static buffer with ID rendering instead of duplicating data.
5499 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Fixed a channel user mode bug when joining to a channel server gave
5502 everybody channel founder rights, oops.
5504 * We mark ourselves as the router of the incoming server connection
5505 if we are router ourselves. This way we can check in some packet
5506 sending functions whether it is locally connected server. For
5507 incoming router connections we put NULL.
5509 * For router sending packets locally means now always sending the
5510 packet cell wide; to local clients and local servers. For normal
5511 server sending packet locally means sending it to only local
5514 * Fixed the JOIN command to really work in router environment. If the
5515 channel is created it is always created by the router. Router is
5516 also responsible of making the initial joining to the channel,
5517 sending JOIN notify to the sending server and distributing
5518 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5519 does not exist server doesn't do anything else but forward the
5520 command to the router which performs everything.
5522 * Added silc_server_send_channel_key function to send the Channel Key
5525 * Added silc_server_create_channel_key to create new channel key. The
5526 channel key is now re-generated everytime someone joins or leaves
5527 a channel, as protocol dictates. Note: channel->key_len is the
5530 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5533 packet_receive.[ch] to separate packet sending and receiving
5534 routines. The server.[ch] now includes everything else including
5535 actual packet processing (writing and reading data) and other
5538 Renamed silc_server_private_message_send_internal to
5539 silc_server_send_private_message. The routine is still though
5540 used only to relay private messages as server does not send
5541 private messages itself.
5543 Renamed silc_server_new_channel to silc_server_create_new_channel
5544 and added new function sicl_server_new_channel that handles the
5545 incoming New Channel packet. Added also new sending function
5546 silc_server_send_new_channel to send New Channel Payload.
5548 * Added new function silc_server_notify to process incoming notify
5549 packet to the server/router. Server may then relay the notify
5550 to clients if needed.
5552 * Added new function silc_server_new_channel_user to process incoming
5553 New Channel User packet. Router will redistribute the packet and
5554 send JOIN notify to its local clients and locally connected servers
5555 if needed. Normal server will send JOIN notify to its local client
5556 on same channel when received this packet. Added also corresponding
5557 sending function silc_server_send_new_channel_user to sent the
5560 * Added boolean route argument to send_notif_to_channel and
5561 packet_send_to_channel functions to attempt to route the packet
5562 if it is TRUE and send only locally if it is FALSE.
5564 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * silc_server_replace_id now broadcasts the received replace ID
5567 packet if it is not broadcast packet already. The router must
5568 broadcast to inform other routers about changed ID.
5570 * Added backpointer to server's router into SilcServer context in
5571 silcd/server_internal.h.
5573 * Fixed silc_server_packet_broadcast to send correct broadcast
5576 * The channel key is now distributed to the local client as soon
5577 as it is received from the router (in router environment) so that
5578 no other packet may be sent for the channel until client has
5581 * silc_server_remove_channel_user now broadcasts the received
5582 Remove Channel User packet if it is not broadcast packet already.
5583 The router must broadcast to inform other routers about removed
5586 * Added users field into SilcPacketContext that is a reference count
5587 of the context. One can increase the reference count by calling
5588 silc_packet_context_dup which is now changed to just increase the
5589 reference count instead of duplicating the data. The reference
5590 count is decresed by calling silc_packet_context_free that will
5591 free the data after the reference count hits zero.
5593 For now on the packet context and everything allocated into it
5594 (including the raw packet from network) must be freed by calling
5595 the new silc_packet_context_free function. Added also new function
5596 silc_packet_context_alloc that must be used now to allocate the
5597 context. This also means that if a routine is asynchronous from
5598 silc_[client/server]_packet_parse_type the packet context must
5599 be duplicated by calling silc_packet_context_dup. Otherwise it
5600 gets free'd after silc_[client/server]_packet_parse_type returns.
5601 Also, one must remember that if packet is duplicated then its
5602 reference count must be decresed by calling the free function as
5603 many times as it was duplicated.
5605 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5606 from both client and server.
5608 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Made joining to a channel working in router environment.
5612 * Cleaned up JOIN command on server side and create function
5613 silc_server_command_join_channel internal routine to make the
5616 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Changed silc_command_pending list to SilcDList. Also, added
5619 `ident' field to SilcServerCommandPending structure to identify
5620 the reply and to call correct callback.
5622 Added silc_server_command_pending_check function to replace the
5623 corresnponding macro. The silc_command_pending list is not
5626 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5627 to set identifier to previously allocated Command Payload. It
5628 is used to set identifier for command when resending Command
5631 * Added silc_command_payload_encode_payload to encode Command
5632 Payload buffer from SilcCommandPayload structure.
5634 * Added silc_argument_payload_encode_payload to encode Argument
5635 payload buffer from SilcArgumentPayload structure.
5637 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Changed WHOIS command to support router connection on server side.
5640 The whois request is always sent to router unless the server is
5641 standalone server. After server has received the reply from the
5642 router will it send the reply to the client.
5644 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5645 broadcast received broadcast packet. The function is used only
5646 by router. The broadcast packet is always sent to the router's
5649 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5650 render given ID to printable string, for log files for example.
5652 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Made basic router to router connections working. At least they
5655 can now connect to each other but nothing really works the way
5656 they are supposed - yet.
5658 * Added new initiator token to RouterConnection configuration
5659 file in silcd/serverconfig.[ch]. It is used to tell whether we
5660 are the initiator to the remote router or whether we'll expect
5661 the other end to connect.
5663 * Moved registering of listener task to silc_server_init, hence
5664 the server starts listenning as soon as it is run, even if it
5665 does not have connections to other routers. Let's see how well
5668 * Changed default connection retry timeouts for more suitable in
5671 * Removed cipher and such arguments from silc_idlist_add_client
5672 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5673 Added new function silc_idlist_add_data to add the keys and stuff
5676 * Added SilcIDListData structure and added it to SilcClientEntry
5677 and SilcServerEntry as their first field in the structure. This
5678 way we can explicitly cast the ID entries to the SilcIDListData
5679 structure and get common data for the entries. In past, we had
5680 to first check what type of connection it is and then cast it to
5681 correct ID entry type. Now, we can directly cast the opaque
5682 pointer to the SilcIDListData (no matter what ID entry it actually
5683 is) and get the data needed.
5685 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5688 in some circumstances even if threre were timeout tasks, though not
5689 IO tasks, but tasks anyway. Now fixed.
5691 * Defined SilcServerConnection structure to hold connection specific
5692 stuff about directly connected servers and routers. The definition
5693 is currently in silcd/server_internal.h. I thought about having
5694 a bit more important role fro this struct but for now it is used
5695 only when connecting to other server (or router actually).
5697 * Added connecting retry support in server when connecting to
5698 router(s). The retry feature implement exponential backoff
5699 algorithm. Also, added SilcServerParams structure to hold default
5700 parameters for server. For now, it include these retry settings
5701 and are hard coded. After server is moded to be as Silc Server
5702 Library this structure will be more important.
5704 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Changed client librarys channel->clients table to SilcList and
5707 changed code accordingly.
5709 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Changed client's channel table to SilcList and changed code
5712 accordingly. Also changed SilcChannelClientEntry to include back-
5713 pointer to the channel so that client entry can use that structure
5714 as list as well and we have fast cross-reference to the channel.
5715 This change dramatically decreased the complexity of channel
5716 handling with client entry and vice versa (removed one extra
5717 loop when searching for channel entry from many functions).
5719 * Changed server->sim from table to SilcDList and changed code
5722 * NAMES command can now be used from user interface. It will show
5723 the user list on the channel, neatly.
5725 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5726 Code now saves realname of the user if it becomes available.
5728 * Renamed configure.in to configure.in.pre and made ./prepare
5729 script to automatically add correct version string to
5730 configure.in which it creates from configure.in.pre.
5732 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * NAMES command reply now shows users mode with the nickname when
5737 * Moved silc_client_ch[u]mode[_char] functions from
5738 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5739 place sucks, they are utility functions and should be in some
5742 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5744 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5747 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added TRQ (efficient deque and list library) into lib/trq. This is
5752 a very good list library that is currently used in the SILC. Defined
5753 SilcList API over the library because I didn't like the API very
5754 much. See lib/trq/silclist.h for the API and examples of how to
5755 use the API. Fixed various places in the code to use the new
5756 SilcList API. The SilcList is meant for lists that has a structure
5757 already defined as a list. It is not suitable to add just some
5758 context to the list (in TRQ, the context is the list actually).
5760 So, I defined SilcDList that can be used for the purpose where
5761 predefined list structure does not exit. This can be used as
5762 such list. Now some context just can be added to the SilcDList.
5763 Currently this list is not used in the SILC just yet, though there
5764 are a lot places where this can replace dynamically allocated
5765 tables and I will fix these places, later, to use SilcDList.
5766 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5767 and use TRQ internally).
5769 Also fixed some annoying warning messages that the original TRQ
5770 code generated. Also minor changes to TRQ's Makefile.in.
5772 * Added support for querying by Client ID to both WHOIS and
5773 IDENTIFY commands into server, as required by the protocol.
5775 * Removed method function pointers from SilcBuffer structure. They
5776 weren't used to anything and just increased the context size for
5777 no good reason. This change also made silc_buffer_alloc and
5778 silc_buffer_free functions inline functions.
5780 * Disabled command flooding detection support until it's fixed so
5781 that it accepts commands in but does not execute them more than once
5784 * Added silc_net_localhost(), to return local hostname, into
5785 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5786 that must be initialized before calling silc_client_init.
5788 * Added new function: silc_server_send_notify_on_channels to send
5789 notify messages to all channels client has joined. It is assured
5790 that the message is sent only once per client.
5792 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5793 lib/silcutil/silcutil.[ch] as silc_format function. The new
5794 function is generic and is used by server as well, not only by
5795 the logging routines.
5797 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5798 the provided version string was not acceptable. Added new function:
5799 silc_ske_check_version into lib/silcske/silcske.h. The function
5800 must be implemented by the application (client or server) and it
5801 does not reside in the SKE library. The function checks the version
5802 string remote end sent.
5804 * Added back pointers (to opaque context and to SilcSocketConnection)
5805 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5807 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5808 duplicate packet context structure.
5810 * Changed `notify' client operation to send same arguments as client
5811 receives from server except for ID's. ID's are mapped to correct
5812 ID entry and that is returned. Also, if channel entry is not sent
5813 by server but the notify is for channel the channel entry is sent
5814 to application (otherwise application doesn't know that it is for
5815 channel (library gets it from packet's Destination ID)).
5817 * Added silc_client_remove_from_channels into client library to
5818 remove a client from all channels it has joined to. Used when
5819 received SIGNOFF notify from server. Added also new function
5820 silc_client_replace_from_channels to replace old ID entry with
5821 new ID entry on all channels. Used when received NICK_CHANGE
5824 * Fixed ID Cache list handling in silc_idlist_get_client in
5825 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5826 to get (or query) client by ID.
5828 * Updated TODO list.
5830 * Added connection authentication status message defined by the
5831 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5832 support for these into the code in client and server side.
5834 * Added generic function silc_client_send_command to send any command
5835 with variable argument list. Application should use this function
5836 to send commands if the command functions provided by the library
5837 does not suite for the application's user interface needs.
5839 * Added new `failure' client operation. Application is notified about
5840 received failure packet if client is executing a protocol. In this
5841 case the protocol's execution has failed.
5843 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5844 is required by the protocol.
5846 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5847 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5850 * Added status flag to SilcSKE object to indicate realtime status
5851 of the SKE protocol.
5853 * Application receives now exactly same command reply arguments as
5854 the library receives from server. However, if ID is received the
5855 corresponding ID entry is returned to the application (eg. Client
5856 ID is mapped to correct SilcClientEntry entry and that is returned).
5857 Changed command_reply client operation due to this change.
5859 * Changed all ID's in commands and in command replys as ID Payloads.
5860 Change affected both client and server side codes.
5862 All ID's sent in SILC network (with execption of ID's in SILC
5863 Packet header) are sent in ID Payload to support variable length
5866 * Server now notifies nick changes and notifies all clients on
5867 the channels about the new nickname (about the new Client ID,
5870 * Implemented CMODE command to change channel modes. Supports all
5871 channel modes defined by the protocol specs except ban and invite
5872 lists. (Also, private channel key mode is supported but support for
5873 setting private channel key in client is missing, thus, this mode
5874 has no effect on client side (except that server requires that the
5875 client uses private channel key and normal channel traffic does not
5878 Also, invite mode works per se, but INVITE command does not work
5879 yet correctly, so you can set channel as invite only channel but
5880 inviting clients to the channel does not work (it is yet to be
5881 thought what's the best way to do it).
5883 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5884 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5885 Implemented CUMODE command to change user's mode on the channel.
5886 Supports all modes defined by the protocol specs.
5888 * Added NAMES command reply to return users modes on the channel.
5890 * Removed unnecessary and slow ciphers from lib/silccrypt.
5892 * Set SO_KEEPALIVE option to connection sockets by default.
5894 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5896 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5897 redefined the Notify Payload into protocol specs.
5899 * Added silc_id_payload_parse_id to get ID directly from raw
5902 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5905 accept searching by Client ID as well.
5907 * Added support for LEAVE and SIGNOFF notify types in client library.
5909 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5910 to parse ID Payload from raw data.
5912 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Added flags parameter into silc_ske_assemble_security_properties
5915 function in lib/silcske/silcske.[ch].
5917 * Changed notify client operation to fit better for notify messages
5918 sent by server. The notify payload received from server is now
5919 passed to the application (after parsing it to SilcNotifyPayload).
5920 It is application's responsibility to retrieve the arguments
5921 from the payload and show the message the way it wants. The message
5922 sent by server is implementation specific.
5924 * Changed public keys to comply with the protocol specification.
5925 Old public keys are not supported anymore and are not compatible.
5927 * Removed nickname from Channel Payload as the latest draft removed
5928 it. The client must resolve the nickname from the NAMES command
5929 reply received when it joined the channel.
5931 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5933 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Fixed some errors in protocol specification drafts.
5937 * Created lib/silccore/silcnotify.c to implement Notify Payload
5938 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5939 generic payloads described by protocol specifications. The file
5940 includes implementations for ID Payload and Argument Payload.
5942 * Changed Command Payload implementation to use the new Argument
5943 Payload. Changed command_xxxx_payload to command_payload_xxxx
5944 to comply with SILC coding conventions.
5946 * Added suppport for Argument Payload handling in Notify Payload
5947 implementation as protocol requires it. Added the new support
5948 into server and client lib as well.
5950 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Added support for multiple nicknames on same channel. [n] is
5953 added locally to the nickname if there are more than one same
5954 nicknames on the channel.
5956 * Server now sends all nicknames that matched WHOIS request.
5957 Client also shows the list received from server.
5959 * Added TOPIC command to client side. User can now set and show
5960 current topic on channel.
5962 * Added MOTD command to client and server. Also, server sends the
5963 motd when client connects to the server.
5965 * Changed version strings to comply ISO 8601.
5967 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Fixed protocol error handling in client library. It should now
5970 cope even if the SKE fails for some reason.
5972 * Made new protocol specification drafts for submitting to IETF.
5974 * Implemented TOPIC command to server in silcd/command.c.
5976 * Added two new notify types into lib/silccore/silcnotify.h:
5977 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5978 notify nickname change and topic setting/change on a channel.
5980 * API change of command_reply operation in client library. The
5981 application gets now the status type received from server as well.
5983 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5987 * Cras fixed and optimized the packet handling even further and
5988 it should work now. Minor change to the prototype of function
5989 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5991 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Added new function into lib/silcutil/silcschedule.[ch]:
5994 silc_schedule_with_fd to select() a specified fd. The function
5995 returns after timeout expires or data arrives or goes. The
5996 function is used by packet routines to wait that all data is
5997 received from network.
5999 * Fixed data reading from network in lib/silccore/silcpacket.c.
6000 The code now assures that all data is read from the fd and then
6001 continues packet processing. This was a bug fix since the code
6002 used to drop some data in some circumstances.
6004 * Added new function into lib/silcclient/client.[ch]:
6005 silc_client_start_key_exchange to start key exchange after
6006 connection has been established to server. The code internally
6007 now uses this funtion but its main purpose was to provide it
6008 for applications that perform their own connecting. After
6009 application has created a connection it merely calls this
6010 function to start the key exchange between client and server.
6011 The library takes care of everything else after that.
6013 Updated also lib/silcclient/README to explain the usage of
6016 * Do not send to application information that connection has
6017 been established. Application gets notified it by connect
6020 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Applied cras's patch to add silc_schedule_one function. The
6023 function runs scheduler once and returns.
6025 * Fixed the scheduler after cras messed it up. The timeout
6026 handling works now as it's supposed to work.
6028 * Added into lib/silccore/ silcnotify.h to include notify
6029 message types support. Changed silc_server_send_notify*
6030 functions, in server.[ch], to support those new notify types.
6031 Added the support for the notify types into client library,
6032 as well. Added new notify client operation into ops.h in
6035 * Changed silc_server_packet_send_to_channel to send normal
6036 packets instead of just channel message packets. The function
6037 is now used to send the notify packets to channels. It is not
6038 used to send channel message packets anymore, as server never
6041 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6042 va_arg()s as it seems to require it nowadays. I guess, if SILC
6043 is compiled with older va_arg() the new code should work anyway.
6045 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Splitted core library. Core library (lib/silccore) includes
6048 now only SILC protocol specific core (and common) components.
6049 Created new utility library (lib/silcutil) that includes more
6050 generic purpose stuff. The stuff for util library was taken
6051 from the old core library. This was minor and easy split.
6053 * Created SILC Client Library (lib/silcclient) that includes
6054 implementation of the SILC client without user interface. This
6055 was major move from silc/ directory. The code has been changed
6056 so that it is transparent towards the user interface. The
6057 silc/ directory includes now the same user interface as before
6058 and it uses the new client library. Read lib/silcclient/README.
6059 Basicly, the client library performs everything else related
6060 to SILC except user interface handling. Also, configuration
6061 files are considered to be part of user interface and library
6062 does not handle them.
6064 This change also changed a lot of structures, function naming etc.
6065 Most important change was that SilcClientWindow object was
6066 renamed to SilcClientConnection in the client library. Created
6067 also new file lib/silcclient/ops.h. Also added new files
6068 silc/local_command.[ch] and silc/client_ops.[ch].
6070 All these changes were made to make it easier for user interface
6071 designers to create what ever user interface for the SILC client
6074 It is also expected that the server will be moved to lib
6075 directory as well and SILC Server Library will be created;
6076 sometimes in the future.
6078 * Removed Local commands from lib/silccore/silccommand.h as
6079 they are application specific and new client library does not
6080 handle any of those anymore.
6082 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6083 old client implementation in silc/.
6085 * Added support for callback functions in SILC_LOG_* macros.
6086 Application can now set its own callbacks that will be called
6087 instead of using the default functions that will always print
6088 the debug messages to stderr (or stdout). Also, debugging can
6089 now be disabled by setting silc_debug to FALSE and re-enabled by
6090 setting it to TRUE. Note, that logging will still work even
6091 if debugging is disabled.
6093 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6094 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6095 silc_log_reset_debug_callbacks.
6097 * To enable debugging in silc client one must give now -d
6098 option on command line.
6100 * Changed silc_schedule_init to automatically allocate task queues
6101 if they are not allocated before calling it.
6103 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Added GMP 3.1 into math library.
6107 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6110 a channel in SILC network. The packet is used by servers and
6111 routers to notify other routers that user has left a channel.
6112 This little feature was missing until now. Added the feature
6113 to protocol specification as well.
6115 Added functions: silc_server_send_remove_channel_user and
6116 silc_server_remove_channel_user into server.[ch].
6118 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6119 lib/silccore/silcpacket.h. However, they are not implemented
6122 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Fixed joining to a channel and sending channel messages
6125 between server and router. The channel message sending should
6126 now work inside a cell.
6128 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Fixed the private message sending between server and router.
6131 The private message sending should now work inside a cell.
6133 * Added silc_server_replace_id into server.[ch] to replace
6134 existing ID in the SILC network.
6136 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6137 and silc_idlist_replace_server_id into idlist.[ch] in server.
6139 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Fixed the server to server connections. Server can again now
6142 connect to router. Router to router connections probably does
6145 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Added dynamic protocol registering support. Now protocols can
6148 registered and unregistered on the fly. Patch by cras.
6150 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added lib/contrib directory to hold routines that some platforms
6153 don't have but are needed by SILC.
6155 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6156 into lin/contrib to provide getopt() and getopt_long() for
6157 those who don't have it.
6159 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Added AWAY command to client. When away message is set and
6162 client receives a private message packet the client automatically
6163 replies to the sender with the away message.
6165 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6166 bug seemed to be the cause of recent problems when compiling
6169 * Added version detection support to SKE protocol specification
6170 and added the new changes to the SKE implementation as well.
6171 There were other minor changes in the SKE protocol as well.
6173 Many changes in lib/silcske/silcske.[ch] and in
6174 lib/silcske/payload.[ch].
6176 * Added ^U functionality, clear input line. Patch from cras.
6178 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Mainly small bugfixes on core library. Fixed some debugging
6181 logging and buffer overflow in silclog.c.
6183 * Updated config.sub and config.guess on the distribution tree.
6185 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Added command lagging support in server. Client may execute
6188 commands now only once in two seconds.
6190 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Optimized packet reception. MAC computation and checking is now
6193 also more optimized. A lot previously duplicated code is now
6194 used as generic by both client and server.
6196 * Fixed key pair generation in clientutil.c
6198 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Added into lib/silccore/silcbufutil.[ch] new function;
6201 silc_buffer_realloc.
6203 * Moved generic packet sending/encryption functions to
6204 lib/silccore/silcpacket.[ch] from client and server. Some
6205 rewriting of the functions.
6207 * Moved all generic packet reception/decryption functions to
6208 lib/silccore/silcpacket.[ch] from client and server. The
6209 packet processing is now much cleaner in both client and server.
6210 These were major changes in both client and server.
6212 * Created many common functions in server to do packet sending.
6213 Previously code were duplicated a lot, this has been removed
6216 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Rewrote major parts of the ID cache system. Don't know
6219 whether it is better now or not but at least the API is more
6222 * Major rewrite on ID cache stuff on client because of the ID
6223 cache API changes. Added idlist.c to client.
6225 * Also major rewrite on ID cache stuff on server as well.
6226 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6227 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6228 in hand, instead they are all put into the ID cache system now.
6229 All server_idlist_* routines uses ID cache now instead of
6230 traversing its own lists (those lists does not exist anymore).
6231 SilcIDList though still exists. Also, SilcXXXEntry's are
6234 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Finally made the SKE implementation compliant to the protocol
6237 specification. All mp integers are now binary encoded as
6238 opposed being HEX encoded.
6240 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6243 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6244 functions: silc_[encode/decode]_pem. Also added function
6245 silc_encode_pem_file to PEM encode with newlines ('\n') for
6248 * SILC public keys are now encoded either PEM or binary. Same
6249 option is for private keys as well. By default private keys
6250 are binary encoded and public keys PEM encoded. Silly HEX
6251 encoding were removed.
6253 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6254 function to create fingerprints.
6256 * Fixed a bug in SHA1; does not change the original data anymore.
6258 * Partly implemented INFO command on client and server side.
6259 Fixed CLEAR command. Changes to SERVER command; show current
6260 server(s) when giving command without arguments. Added
6261 VERSION command to client.
6263 * Added check to server that unregistered connections cannot
6264 execute commands (unless it is specificly allowed).
6266 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * Fixed screen refresh.
6270 * Fixed channel joining bug from client. On some circumstances
6271 client tried to join to a channel it had already joined.
6273 * Added public key verification process into client's protocol.c.
6274 The client now verifies the public key from user and saves
6275 it into ~./silc/serverkeys/ directory.
6277 Added into: clientutil.[ch]: silc_client_verify_server_key.
6279 * Changed SKE protocol's silc_ske_initiator_finish function
6280 to accept callback function that verifies the received public
6281 key. Removed old silc_ske_verify_public_key function.
6283 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6286 silc_pkcs_private_key[_data]_set.
6288 * Made the password and public authentication more cleaner in
6289 server's protocol.c.
6291 * Removed historic and obsolete protocol `channel_auth' from
6292 both client and server.
6294 * Removed wrong way of sending command status messages from
6295 server to client in server's command.c. The old way violated
6296 protocol specification.
6298 Changes to silccore/silccommand.[ch]: removed
6299 silc_command_encode_status_payload -> not needed anymore,
6300 changed silc_command_encode_payload_va to accept extra
6301 argument on variable argument list. The argument type must
6302 now be provided to the function. Also, added new function:
6303 silc_command_encode_reply_payload_va which is same as
6304 normal command_encode_payload_va except command status type
6305 is provided as extra argument.
6307 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Added ~./silc directory handling. The directory includes the
6310 public and private keys for the client.
6312 Added silc_client_check_silc_dir, silc_client_create_identifier
6313 and silc_client_load_keys.
6315 * Implemented SILC protocol compliant public key. Added public
6316 and private key saving to and loading from files.
6318 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6319 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6320 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6321 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6322 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6324 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6325 silc_pkcs_load_[public/private]_key.
6327 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added silc_server_get_route (route.[ch]) to get connection
6330 data for the fastest route for given ID.
6332 * Implemented INVITE command on client and server. The command
6333 were re-defined in the SILC Protocol Specification and the
6334 implementation now complies with the specification.
6336 * Implemented PING command on client and server.
6338 * Implemented NAMES command on client and server. The server side
6339 supports currently only normal server not router server yet.
6340 Some changes to NAMES definition in SILC protocol specification.
6342 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Implemented LEAVE command on client and server.
6346 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6347 again. This change was made to the protocol as well. Server
6348 should not violate the protocol specification anymore.
6350 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6353 was tested. SOCKS4 was not but should work anyway.
