1 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Redefined the Status Payload to include now two 8 bit fields,
4 instead of one 16 bit field. This now makes it possible to
5 send list of errors. Updated the protocol specs and the code
6 in core library, client library and server. Protocol TODO #1.
7 Affected files are lib/silccore/silccommand.[ch],
8 lib/silcclient/command_reply.[ch], silcd/command.c,
9 silcd/command_reply.c and silcd/packet_receive.[ch].
11 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
13 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
14 must be handled by the application and should tell the application
15 that an error message was already printed, and it should print the
16 config coords (line, filename, ...). Affected files are
17 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
19 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
20 server config parsing code more readable.
22 Fixed a bug in the fetch_logging() config callback.
24 Affected files is silcd/serverconfig.c.
26 * Drop root privileges when started in foreground. Don't drop them
27 if debugging also. Affected file is silcd/silcd.c.
29 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Added more IM-like features by introducing new user modes
32 for setting various presence information. Added new modes:
33 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
34 specs and code. Protocol TODO #19. Affected files are
35 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
36 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
38 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
40 * Added STATS command to the protocol after all, to return
41 various statistical information about the network. It can
42 be used by clients to retrieve statistical information, and
43 servers may use it to to fetch cell and network wide
44 statistics from router. Updated the protocol specs and
45 implemented it to the server. Protocol TODO #16.
46 Affected files are lib/silccore/silccommand, silcd/command.[ch],
47 silcd/command_reply.[ch].
49 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
51 * The LIST command reply in client libary now adds new channel
52 entry if the returned channel doesn't exist yet in cache,
53 and returns the channel entry to the application in the
54 command_reply client operation. Affected file is
55 lib/silcclient/command_reply.c.
57 * Changed the channel message payload's MAC generation to
58 include the IV in the MAC as well. This way all relevant
59 parts of the channel message payload are authenticated also
60 with the channel message MAC (and not only by packet MAC).
61 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
62 Affected file is lib/silccore/silcchannel.c.
64 * Fixed the SKE to save the remote version, since the
65 silc_ske_parse_version mistakenly checked wrong version,
66 after it replaced the start payload. Affected files are
67 lib/silcske/silcske.[ch].
69 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

76 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
77 files are lib/silcutil/silcstrutil.[ch].
79 * Defined that the security property fields in SKE SHOULD be
80 UTF-8 encoded, defined that version string MUST be US-ASCII
81 encoded, defined that passphrases sent in connection
82 authentication protocol MUST be UTF-8 encoded. Implemented
83 these to the client and server. Defined also that other
84 passphrases sent in the protocol MUST be UTF-8 encoded.
85 Affected files are lib/silcske/silcske.c,
86 lib/silcclient/protocol.c, silcd/protocol.c,
87 silcd/serverconfig.c, and lib/silccore/silcauth.c.
89 * Changed the silc_client_close_connection interface to not
90 need the SilcSocketConnection which should not be visible
91 to application. Affected files are lib/silcclient/client.c
92 and lib/silcclient/silcclient.h.
94 * Rewrote the text for Private Message Key Payload in the
95 protocol specification. Protocol TODO #11.
97 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Upgraded the protocol version to 1.1, updated protocol specs
102 * Added the nickname as new argument to NICK_CHANGE notify and
103 added it to protocol specs and implemented it to client and
104 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
105 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
106 lib/silcclient/client_notify.c.

110 Protocol TODO #13. Affected files are silcd/command.c,
111 silcd/packet_receive.c, packet_send.[ch],
112 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
113 The killer's client entry is now returned to application in
114 the `notify' client operation.
116 * Fixed the Max Argument fields that had too large value set
117 in the protocol specs. Protocol TODO #14.
119 * Added the LEAVE command reply to return the ID of parted
120 channel. Updated protocol specs and implemented it to the
121 client and server. Protocol TODO #15. Affected files are
122 silcd/command.c, lib/silcclient/command_reply.c. The channel
123 entry is now returned to application in the `command_reply'
126 * Rewrote the version SKE version checking in client libary
127 and in server to use the silc_parse_version_string. Affected
128 files are lib/silcclient/protocol.c, silcd/protocol.c.
130 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
131 commands that was missing it, and updated protocol specs and
132 the server implementation. Protocol TODO #10. The affected
133 file is silcd/command.c.
135 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
136 generic reply to a generic request (REQUEST flag), and
137 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
138 way. A draft-riikonen-silc-flags-payloads-00.txt is written
139 to define the payload for DATA flag. Added the flags to
140 the implementation. Protocol TODO #9. Affected file is
141 lib/silccore/silcchannel.h.
143 Changed the client library to return the message length
144 to application as well in the channel_message and private_message
145 client operations. Affected files are
146 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
147 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
148 and lib/silcclient/client_ops_example.c.
150 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
151 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
152 the channel. Updated protocol specs and impelemented this
153 to client and server. Protocol TODO #6. Affected files are
154 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
155 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
157 Added new options m and M to CMODE command in Irssi SILC
158 client to set these modes.
160 * Deprecated all administrative commands from SILC protocol
161 since they are highly implementation specific commands.
162 Updated protocol specs. Moved the old commands in
163 implementations to private range of command types. Affected
164 files are silcd/command.c, lib/silcclient/command.c and
165 lib/silcclient/command_reply.c. Protocol TODO #8.
167 * Fixed a bug in server where sending unknown command crashes
168 the server. Affected file silcd/command.c.
170 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
172 * Added SILC_PROTOCOLVERSION macro to check protocol version
173 of a socket connection. The affected file is
174 lib/silcutil/silcsockconn.h.
176 * Added better error logging in rekey protocol. Affected file
179 * Do not check public key types in SKE during rekey. Affected
180 file lib/silcske/payload.c.
182 * Fixed the rekey protocol with PFS, which was totally broken.
183 Affected file silcd/protocol.c.
185 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
187 * Some client implementations quit network by doing first LEAVE
188 and then immediately SIGNOFF (like Bombyx). We now do check
189 after a short time after LEAVE notify and check whether the
190 client is still valid after LEAVE, and if not we remove it from
191 cache. Affected file is lib/silcclient/client_notify.c.
193 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
195 * Merged version 1.1.4 of zlib. Even if it not currently in use,
196 it's good not to have security holes here.
198 * Fixed a negative refcount situtuation for the config context.
199 Affected file is silcd/serverconfig.c.
201 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
203 * ROBOdoc documented lib/silcutil/silcutil.h.
205 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
207 * Optimized even more the SilcPacketContext structure. Now
208 totally saved 16 bytes of memory per context after optimization.
209 Affected files are lib/silccore/silcpacket.[ch].
211 * Made strict checks for valid SILC IDs. Affected file is
212 lib/silccore/silcid.c.
214 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

217 silc_hash_register, silc_hmac_register and silc_pkcs_register
218 to const. Affected files are lib/silccrypt/silccipher.[ch],
219 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
221 * Changed the silc_get_username and silc_get_real_name to
222 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
224 * Fixed the Irssi SILC Client to use the silc_get_username and
225 silc_get_real_name insted of glib routines since the glib
226 routines only corrupt stack. Fixes the Irssi SILC to work in
227 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
229 * Fixed the Irssi to not use g_get_home_dir since it crashes
230 or returns garbage on cygwin and corrupts stack. Added function
231 get_home_dir to Irssi routines. Affected files are
232 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
234 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

237 entry structure. Optimized SilcTask structure. Optimized
238 SilcPacketContext structure.
240 Affected files lib/silcsftp/sftp_fs_memory.c,
241 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
243 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * And yet again reverted back the config thing since Johnny
246 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
249 * Fixed memory leaks from config object. Affected files are
250 silcd/serverconfig.[ch].
252 * Added support for adding new connections to the server in rehash.
253 After rehash they take effect.
255 Added support for changing the maximum allowed connections in
256 rehash. The number can grow but going smaller is not supported.
258 Added function silc_server_num_sockets_by_remote to the
259 silcd/server_util.[ch].
261 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
263 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
265 * Added preliminary checking during config parsing for a valid
266 public/private key and removed further checks in the code.
267 Affected files are silcd/serverconfig.[ch], server.c.
269 * Moved functions silc_server_drop() and silc_server_daemonise()
270 from server.c to silcd.c since they are stricly related to
271 the application activity.
273 * Reverted a small part of the automatic ref/unref since
274 it caused a double unref in some situations. Affected
275 files are silcd/silcd.[ch], server.c, serverconfig.c.
277 * Added some .cvsignore files in the lib directory.
279 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
281 * Fixed silc_net_gethostbyaddr to correctly resolve by
282 address. Affected file lib/silcutil/silcnet.c.
284 * Fixed the notify relaying to client. The HMAC to be used
285 with relayed packets ws wrong and caused decryption failure
286 at the client end. Affected file is silcd/packet_receive.c.
288 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Created new branch silc_protocol_1_0_branch.
292 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
294 * Changed the silc_server_config_* routines to be SilcServer
295 independent. They are now officially application specific code
296 and not part of generic server implementation. Affected files
297 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
299 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
301 * Added automatic referencing of config context in the
302 silc_server_config_alloc, and automatic unreferencing in the
303 silc_server_config_destroy. Affected files are
304 silcd/serverconfig.[ch], silcd/silcd.c.
306 * Fixed the silc_log_quick handling in the logging routines.
307 It didn't log quickly when it was TRUE. Affected file is
308 lib/silcutil/silclog.c. Also the flush delay was set even
309 if it was 0 in config file. Affected file is
310 silcd/serverconfig.c.
312 * Added support for changing key pair of the server in rehash.
313 Affected file silcd/server.c.
315 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Fixed the TOPIC_SET notify to not cras. It changed the topic
318 too early, before getting the channel entry. Affected file
319 is silcd/packet_receive.c.
321 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
323 * Added functions silc_server_config_[ref/unref], these are used
324 to prevent that the config object is destroyed.
326 No longer directly affect global variables silc_log_quick and
327 silc_log_delay, they are first cached inside the config object
328 and then applied with silc_server_config_setlogfiles().
330 silc_server_config_set_defaults() is now internal to
331 serverconfig.c, there are no reasons to show this internal stuff
334 Affected files are silcd/serverconfig.[ch].
336 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
337 fprintf's to stderr, since some code may be executed again after
338 the server went into the background. Affected files are
341 * Added rehash support. Added function silc_server_rehash() that
342 will perform all the basic tasks of the rehashing procedure.
344 * Added command line option `-x, --hexdump'. This will enable the
345 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
346 The option `--hexdump' implies `--debug'.
348 * Fixed a bad bug in the logging APIs (silcutil library) where
349 the application would crash after calling silc_log_reset_all().
351 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
353 * Fixed the KICKED notify handling in client library to
354 correctly remove the channel and all entries from the
355 channel when I was kicked. This bug crashed the client.
357 Fixed yet another but in KICKED notify handling to remove
358 the kicked client correctly from the channel.
360 Affected file is lib/silcclient/client_notify.c.
362 * Fixed a minor bug in looking up correct client entry
363 in KICKED notify in server. Affected file is
364 silcd/packet_receive.c.
366 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
367 sources correctly to distribution. Fixes --with-gmp option.
369 * Removed the manual rehashing from ID Cache, and changed it
370 to use the SILC Hash Table's auto rehash feature. Affected
371 file is lib/silccore/silcidcache.c.
373 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
375 * Fixed a bug in the silc_client_nickname_format function that
376 handles the multiple same nickname formatting. Two clients
377 with same nickname caused problems after the first one left
378 and rejoined. It didn't format the nickname correctly.
379 Affected file is lib/silcclient/idlist.c.
381 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
383 * Don't change the topic if olod topic is same as new one.
384 Affected file is silcd/packet_receive.c.

388 * Added cross-reference support to the SILC Documentation
389 generator. All types across all HTML files are now cross-
390 referenced. Affected files util/robodoc/generator.c and
391 scripts/silcdoc/silcdoc.
393 * Added file lib/silcutil/silctypes.h to include all the
394 arithmetic type definitions and some macros. Removed
395 includes/bitmove.h and moved macros to silctypes.h.
397 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
399 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

404 now returns the type of the ID to the sent pointer. Affected
405 file is lib/silccore/silcid.[ch].
407 * Added check for CMODE_CHANGE notify type that mode change is
408 allowed by the sender. Affected file silcd/packet_receive.c.
410 * Added check for CUMODE_CHANGE notify type that mode change is
411 allowed by the sender. Affected file silcd/packet_receive.c.
412 Added the ID type as CUMODE_CHANGE notify type as argument
413 to the `notify' client operation. Affected files are
414 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
416 * Added function silc_client_add_server to the client library.
417 Added support for resolving also channel and server info when
418 received unknown entity in notify packet. Affected files are
419 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
421 * Added function silc_command_get_status to return the command
422 status from the command reply's argument payload. Affected files
423 are lib/silccore/silccommand.[ch].
425 * Added check for KICKED notify type that the kicking is
426 allowed by the client. Affected file silcd/packet_receive.c.
428 * Created function silc_get_input which can be used to get input
429 (echo on or off) from user on command line. Affected files are
430 lib/silcutil/silcutil.[ch].
432 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
434 * Optimized silc_server_packet_relay_to_channel function.
435 Added new function silc_channel_message_payload_encrypt which
436 can be called directly if channel message payload needs to
437 be encrypted and is already encoded (no need to call _encode
438 function). Packet relaying is now done by router without any
439 extra memory allocations. Affected files are
440 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
443 * Fixed the INVITE notify handling. It took wrong arguments
444 as invite list and invite delete. Affected file is
445 silcd/packet_receive.c.

461 by the client. Affected files are silcd/server_util.[ch],
462 silcd/packet_receive.c and silcd/command.c.
464 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
466 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
467 ID length. It ignored that ID can be IPv6 based as well.
468 Affected file lib/silccore/silcpacket.h.
470 * Fixed the silc_id_id2str and silc_id_str2id to take the
471 IPv6 address offset's into consideration. Affecte file is
472 lib/silccore/silcid.c.
474 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
476 * Fixed the internal Unix scheduler functions to check for
477 NULL context they may receive. The affected file is
478 lib/silcutil/unix/silcunixschedule.c.
480 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
482 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
483 can specify different directory with --home command line
484 parameter. Affected files irssi/src/silc/core/client_ops.c,
487 * SILC-specific commands aren't now executed if the active server
488 isn't of SILC-type, so there won't be problems with having
489 IRC and SILC protocol support in same client. Affected files
490 irssi/src/silc/core/silc-channels.c, silc-servers.c,
493 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
495 * Improved the signal support in SILC Schedule. Added new
496 function silc_schedule_signal_call which is used by application
497 to mark a signal to be called. It is now safe to perform
498 any kind of tasks in signal callbacks since it is guaranteed
499 that the application specified signal callback is called
500 after the signal is over. Affected files are
501 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
503 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
505 * Added `name' field to SilcChannelPrivateKey to represent
506 application given name for the key. Moved also the context from
507 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
508 Added the `name' argument also to the function
509 silc_client_add_channel_private_key.
511 Added function silc_client_current_channel_private_key to set the
512 current channel private key in use.
514 Added "change" command to KEY command which can be used to change
515 the current channel private key. Bound the command also to
518 Also affected files lib/silcclient/client_channel.c,
519 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
521 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
523 * Added silc_rng_get_byte_fast function in to the
524 lib/silccrypt/silcrng.[ch].
526 * Changed the interface of silc_packet_assemble and the
527 silc_packet_send_prepare. If silc_packet_assmble is now
528 called the application does not call silc_packet_send_prepare
529 because the library will call it automatically. These
530 interfaces now also return a reference to the outgoing buffer
531 which includes the assembled packet, which the application can
532 use to encrypt the packet.
534 Affected files are lib/silccore/silcpacket.[ch],
535 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
536 silcd/packet_send.c, server_backup.c and packet_receive.c.
538 * Fixed a packet sending bug on very high load, where outgoing
539 packet queue wasn't handled correctly and packets got corrupted.
540 Affected files are lib/silcutil/*/silc*sockconn.c,
541 lib/silcclient/client.c and silcd/server.c.
543 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
545 * Added macro SILC_PACKET_DATALEN which can be used during
546 packet assembling to check whether the data to be added to
547 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
548 len is truncated until it fits it.
550 Added checks for maximum length of channel message payload and
551 private message payload also.
553 Added checks for maximum packet length in server and in
556 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
557 lib/silcclient/client.c, lib/silccore/silcchannel.c and
558 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
559 lib/silcclient/client_prvmsg.c.
561 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
563 * Added silc_server_packet_queue_purge call to the
564 silc_server_disconnect_remote to assure that all data in the
565 queue before disconnecting is sent to the network. Affected
568 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
570 * Added the deleting of server's own ID cache entry to the
571 silc_server_free function. Free also everything else that
572 has been allocated in silc_server_init. The affected file
575 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
577 * Added functions silc_parse_version_string, silc_version_to_num,
578 and silc_ske_parse_version to parse SILC protocol style version
579 strings. Affected files lib/silcutil/silcutil.[ch] and
580 lib/silcske/silcske.[ch].
582 * Added new configuration params: version_protocol, version_software
583 and version_software_vendor to specify what version the remote
584 host must at least be to be able to connect to server. The vendor
585 string can be regex matched too. Added new function
586 silc_server_connection_allowed to check maximum number of allowed
587 connections, and allowed versions for incoming connections.
588 Affected files are silcd/server.c, server_util.[ch] and
591 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
593 * Added preliminary support for signals in scheduler. The
594 signals we care about are now blocked always when the scheduler
595 is locked. This way we can synchronise the use of signal with
596 scheduler. It is guaranteed that when signal occurs the scheduler
597 is not locked, and thus new tasks can be safely added to the
600 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
601 to silc_schedule_internal_init and silc_schedule_internal_uninit.
602 Added new platform specific routines
603 silc_schedule_internal_signals_[un]block and
604 silc_schedule_internal_signal_[un]register.
606 Added new functions to SILC Schedule API:
607 silc_schedule_signal_[un]register. Each signal that application
608 is going to use should be registered to the scheduler.
610 Affected files are lib/silcutil/silcschedule.[ch],
611 lib/silcutil/*/silc*schedule.c.
613 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Check for unauthenticated client and server in the
616 silc_server_new_client and silc_server_new_server functions.
617 Affected file silcd/packet_receive.c.
619 * Added function silc_string_is_ascii to check whether given
620 string is 7-bit ASCII string. Affected files are
621 lib/silcutil/silcutil.[ch].
623 * Added function silc_id_is_valid_server_id into the
624 silcd/serverid.c and added checking for valid Server ID's in
625 silc_server_new_server. The Server ID must always be based
626 on the server's public IP address.
628 * Added logging of DISCONNECT packet message in the server.
629 Affected file silcd/server.c.
631 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Changed all library interfaces that use Global RNG to also
634 accept SilcRng as argument. Affected files are
635 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
636 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
637 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
638 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
641 * Added function silc_pkcs_generate_key to the
642 lib/silccrypt/silcpkcs.[ch] for applications so that they
643 don't need to do pkcs->pkcs->init calls anymore.
645 * Remove SilcSocketConnection from the SFTP API since it really
646 wasn't needed there. The application has the information
647 saved in its contexts anyway and the SFTP layer doesn't need
648 know about it. Affected files lib/silcsft/silcsftp.h and
649 lib/silcsftp/sftp_[server/client].c.
651 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
652 The SilcSimContext is not SilcSim.
654 * Fixed possible buffer overflows in silc_id_render in the
655 lib/silcutil/silcutil.c.
657 * On EPOC the global crypto module lists are not used at all
658 in the crypto library. Added support for using the constant
659 algorithm list on EPOC. Affected files are
660 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
663 * Fixed the handling of third parameter of KICKED notify, since
664 it was mistakenly updated to SILC Protocol 1.0 even though it
665 is to be included in 1.1. Since it is not in 1.0 it is not
666 mandatory, and this fix now handles it only if it is provided,
667 and it is not error if it is not provided. Affected file
668 lib/silcclient/client_notify.c.
670 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
672 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
673 client. Affected file irssi/src/silc/core/client_ops.c.
675 * Merged with Irssi 0.8.4 from irssi.org CVS.
677 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
679 * Check for valid socket connection in client entries before
680 sending any messages. Fixes a crash, but doesn't fix some
681 other underlaying bug that is lurking there. Affected
682 file silcd/packet_send.c.
684 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
686 * $usermode, $cumode and $cumode_space expandos shouldn't do
687 anything with non-SILC server records. Affected file
688 irssi/src/silc/core/silc-expandos.c
690 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
692 * Fixed the silc_net_check_[host/local]_by_sock to support
693 IPv6 bound sockets as well. Now they can return IPv6 addresses
694 as well. Affected file lib/silcutil/silcnet.c.
696 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
697 Affected lib/silcutil/unix/silcunixnet.c.
699 * Fixed ID rendering (at least on some platforms, not NetBSD)
700 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
702 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
704 * Added silc_hash_public_key and silc_hash_public_key_compare
705 functions to be used with SilcHashTable. They can be used to
706 hash public keys and compare public keys in hash table. Affected
707 file lib/silcutil/silcutil.[ch].
709 * Added support for specifying multiple public keys for Client
710 connection section in server configuration file. This makes it
711 possible to accept multiple public keys from same host, or to
712 make a section that accepts any incoming host, and have the
713 accepted public keys listed in the section.
715 Added functions silc_sever_[find/get]_public_key, added the
716 support for this actually to all connection sections but only
717 the Client section is currently allowed to specify multiple
720 Affected files are silcd/server.c, server_internal.h,
721 command.c, protocol.c, server_util.[ch], packet_receive.c.
723 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Merged Irssi 0.8.2 from irssi.org CVS.
727 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
729 * If silc_debug is TRUE, also output standard logging messages
730 to stderr with the debug output.
732 Made silc_log_reset_all() flushing all channels before returning.
733 Also fixed some documentation typos.
735 Affected files are lib/silcutil/silclog.[ch].
737 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Fixed the server to check correctly the amount of connections
740 from single host, by checking also the type of the connection.
741 Fixed also the comparison of number of connections and number
742 of allowed connections. Affected files are silcd/server.c,
745 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
747 * Fixed the USERS command reply to save the user's mode on the
748 channel as well. Fixed JOIN command reply to check whether a
749 client is on channel already and not join it twice. Affected
750 file lib/silcclient/command_reply.c.
752 * Added new file silc-expandos.c into irssi/silc/core/ to return
753 various stuff for various signal for the statusbar etc. updating.
754 Now Irssi SILC client prints channel user modes etc. on the
757 * The user mode (like server/router operator changes) is now shown
758 on the Irssi SILC client's statusbar. The affected files are
759 irssi/src/silc/core/client_ops.c, silc-expandos.c.
761 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
764 to SILC_SCHEDULE_[UN]LOCK macros.
766 * Added more error printing to logs in server code. Affected
767 files silcd/server.c and silcd/protocol.c.
769 * Fixed -S option parsing in Irssi SILC Client. Affected file
770 irssi/src/silc/core/silc-core.c.
772 * Added silc_buffer_alloc_size function. Affected file is
773 lib/silcutil/silcbuffer.h.
775 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
778 constants. Affected files in
779 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
782 * Changed the internal SFTP Memory FS table to const. Affected
783 file lib/silcsftp/sftp_fs_memory.c.
785 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
787 * Fixed the buffer formatting and unformatting routines to
788 check the size of 64 bits types with sizeof(). Affected
789 file is lib/silcutil/silcbuffmt.c.
791 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Removed 0.6.x backwards support.
795 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Changed all integer type names:
798 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
799 to avoid collisions with other libraries using same type names
802 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Added `prefer_ipv6' argument to the functions
805 silc_net_gethostbyname[_async]. If it is TRUE it will return
806 IPv6 address over IPv4. If FALSE IPv4 address is returned
807 even if IPv6 address was found. Affected files
808 lib/silcutil/silcnet.[ch].
810 * Added support silc_net_create_connection[_async] to fallback
811 to IPv4 address if IPv6 address could not be used (like if
812 it doesn't work on a specific system). Affected file in
813 lib/silcutil/unix/silcunixnet.c.
815 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

821 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
823 * Added automatic extern "C" { ... } for C++ compilers so the
824 application does not need to define them. Affected file
825 includes/silcincludes.h.
827 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
828 old name went against naming convention. Applications now
829 include "silcclient.h" instead of "clientlibincludes.h".
830 Removed includes/clientlibincludes.h, it is redundant now.
832 * Renamed includes/version.h to silcversion.h.
834 * Added really preliminary support for OS/2 into the util
835 library. Only thread & mutex API is implemented, others
836 are still to be implemented. Created the lib/silcutil/os2/
837 directory. Created also file includes/silcos2.h.
839 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
841 * Added preliminary BeOS support into the util library.
842 Created lib/silcutil/beos/, and implemented all the needed
843 functions to support SILC on BeOS. Created also file
846 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
848 * Added proper initializations to silc's irssi code, so it's
849 now possible to load it as module. Affected files
850 irssi/src/silc/core/silc-core.c,
851 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
853 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
855 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into

860 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
862 * ROBOdoc documented lib/silcutil/silcmemory.h.
863 Added also new function silc_memdup.
865 * Removed lib/silcutil/silcbufutil.h and moved those routines
866 to the lib/silcutil/silcbuffer.h.
868 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
870 * Added `user_count' to the SilcChannelEntry which now tells the
871 number of users on the channel. The user count is now saved
872 in normal server of global channels as well. Affected files
873 silcd/server.c, idlist.h, packet_receive.c and command.c.
875 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
876 include file utility functions.
878 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
879 instead of calling directly OS routines.
881 * Fixed NICK change printing in Irssi SILC Client. Fixed
882 KICKED notify printing in Irssi SILC Client. Affected file
883 irssi/src/silc/core/client_ops.c.
885 * Fixed a NICK change bug in client library, to not recreate the
886 client_entry->channels hash table everytime nick is changed.
887 Affected file lib/silcclient/client.c.
889 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * ROBOdoc documented the lib/silcske/silcske.h, and improved
892 the SKE interface a bit.
894 * Fixed padding problem in PKCS#1. The padding was not actually
895 random since the random number generator was used incorrectly.
896 This security bug affects only when encrypting with PKCS#1, and
897 it is not currently used at all in SILC. SILC only use signing
898 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
900 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

911 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
912 key_exchange_timeout, conn_auth_timeout, connections_max,
915 Implemented all the new config settings handling in the server.
917 Optimized the use of SKE Mutual flag usage. Use it only
918 if connection authentication protocol is not based in public
921 Renamed all SilcServerConfigSection* to SilcServerConfig*
922 to have a bit shorter names.
924 Affected files silcd/serverconfig.[ch], server.[ch], and
927 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

942 * Fixes to the silcd config template. Affected file is
943 doc/example_silcd.conf.in.
945 * Removed type casts from silc_calloc(), conforming to the
946 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
948 * Removed param_name member from client, server, and router
949 section structs, now identifying the param directly.
951 Added CONFIG_FREE_AUTH macro in config file parsing.
953 Affected files are silcd/serverconfig.[ch].
955 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
957 * Fixed command line parameter handling. All SILC initialization
958 is now done in silc_core_init() which also fixes autoconnecting
961 Affected files irssi/src/silc/core/silc-core.c,
962 irssi/src/fe-text/silc.c.
964 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
966 * Added new configuration options and blocks:
967 keepalive_secs, reconnect_count, reconnect_interval,
968 reconnect_interval_max, reconnect_keep_trying and
969 require_reverser_lookup. Added ConnectionParam block, and
970 implemented the connection parameters when connecting as
971 initiator and when accepting connections as responder.
973 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
974 whether given configuration value has been given already.
976 Affected files silcd/serverconfig.[c], server.[c].
978 * Splitted the doc/example_silcd.conf.in. Separated the crypto
979 algorithm parts and created new file silcalgs.conf, that
980 is now included from the example_silcd.conf.in.
982 * Optimized the silc_server_connect_to_router_second to take
983 the connection configuration object from the SilcServerConnection
984 object instead of finding it during the connecting phase.
985 Added the configuration object to SilcServerConnection struct.
986 Affected files silcd/server_internal.h, server.c.
988 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
990 * Add the client on channel after it was resolved at the
991 channel message receiving, and it was not already on the
992 channel. Affected file lib/silcclient/client_channel.c.
994 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
996 * Fixed the public key authentication to allocate always the
997 destination signature buffer instead of using static buffer.
998 Affected file silcd/protocol.c.
1000 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1002 * Unified the serverconfig.[ch]'s helper function interface.
1003 Affected file silcd/serverconfig.[ch].
1005 * Removed doc/example_silc.conf.in since it is redundant.
1006 The make install will now install irssi/silc.conf file.
1008 * Added new Passphrase and Publickey authentication methods to
1009 config file, allowing both public key and passphrase based
1010 authentication to be set at the same time.
1012 Added `prefer_passphrase_auth' setting in config file which
1013 can be used to set to prefer passwd auth if both passwd and
1014 public key is set. If not set, public key is preferred.
1015 This has effect only when being initiator (responder will try
1018 Added support for authentication with passphrase and public key
1019 at the same time. The passphrase is tried first always since
1020 it is faster to check.
1022 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1024 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1026 * Merged the new SILC Config library, with the server parsing
1027 support. Read the header file silcconfig.h or the toolkit
1028 documentation for the news. Affected files are
1029 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
1030 silcd/command.c silcd/packet_receive.c silcd/packet_send.c

1039 * The silc_cipher_register, silc_hash_register and
1040 silc_hmac_register now checks if the object to be registered
1041 is registered already. Affected files are
1042 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1044 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1054 as header filenames.
1056 * Removed lib/silcclient/README and created HTML file
1057 lib/silcclient/silcclient_using.html, which is now included
1058 as part of Toolkit documentation.
1060 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1062 * Fixed CUMODE_CHANGE notify handling to change the mode of
1063 correct client. Affected file lib/silcclient/client_notify.c.
1065 * Make silc_rng_alloc fail if it cannot allocate the sha1
1066 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1068 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1070 * Fixed the file transfer's key agreement payload to include
1071 zero port also if the hostname is NULL because it could not
1074 Call file transfer monitor callback now also if error occurs
1075 during key agreement protocol.
1077 Changed the silc_client_file_send interface to return the
1078 SilcClientFileError instead of session id. The session ID
1079 is returned into pointer provided as argument.
1081 Check that the file exists locally before sending the
1082 file transfer request at all.
1084 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1086 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1087 error than can occur while key agreement protocol. Affected
1088 file lib/silcclient/silcapi.h.
1090 * Fixed the event_mode CMODE handler to not crash when mode
1091 is changed and +k mode is set in the channel. Affected file
1092 irssi/src/silc/core/silc-channels.c.
1094 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1095 SILC_LOG_WARNING to give out Warning and not Error. Affected
1096 file lib/silcutil/silclog.c.
1098 * Fixed the channel message payload decryption in the function
1099 silc_channel_message_payload_decrypt to not modify the original
1100 buffer before it is verified that the message decrypted
1101 correctly. Otherwise, next time it is called with correct
1102 channel key it won't encrypt since the payload is corrupted.
1103 Affected file lib/silccore/silcchannel.c.
1105 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1107 * Do not constantly resize the window. A fix patch by cras.
1108 Affected file irssi/src/fe-text/screen.c.
1110 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1112 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1113 Affected file lib/silcutil/silcnet.c.
1115 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1117 * Fixed a bug in hash table internal routine for traversing
1118 the table with foreach callback. The current entry may
1119 become invalid in the callback but it was referenced after
1120 the callback returned.
1122 Do not allow auto rehashing of hash table during the
1123 silc_hash_table_foreach operation, for same reasons as it is
1124 not allowed for SilcHashTableList. Affected files are
1125 lib/silcutil/silchashtable.[ch].
1127 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1129 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1130 Win32 DLL. extern's in header files are now declared with
1133 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1135 * Fixed private message handling. It used some old code that
1136 caused the client to crash. Affecte file is
1137 lib/silcclient/client_prvmsg.c.
1139 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Added function silc_client_add_channel,
1142 silc_client_replace_channel_id, and removed functions
1143 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1144 from client library.
1146 * Added cross reference of the joined channels to the
1147 SilcClientEntry, and changed the SilcChannelEntry's
1148 users list to SilcHashTable. The affected files are
1149 lib/silcclient/idlist.[ch].
1151 * Fixed a bug in hash table tarversing. While the hash table
1152 is traversed with SilcHashTableList the table must not be
1153 rehashed. It is now guaranteed that auto rehashable tables
1154 are not rehashed while tarversing the list. Also defined that
1155 silc_hash_table_rehash must not be called while tarversing
1156 the table. Added function silc_hash_table_list_reset that must
1157 be called after the tarversing is over. The affected files are
1158 lib/silcutil/silchashtable.[ch].
1160 * Changed all hash table traversing to call the new
1161 silc_hash_table_list_reset in server and in client library.
1163 * Added function silc_client_on_channel to return the
1164 SilcChannelUser entry if the specified client entry is joined
1165 on the specified channel. This is exported to application as
1166 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1168 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1170 * Fixed founder regaining problem with JOIN command on normal
1171 server. The notify for mode change must be sent always and
1172 not only if !cmd->pending. Affected file silcd/command.c.
1174 * Fixed the WHOWAS command's reply sending to support the
1175 lists correctly. Affected file silcd/command.c.
1177 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * When sending JOIN command to router for processing the
1180 sender's old command identifier was not saved back to the
1181 sender's command context, fixed now. The affected file is
1184 * Create the key in JOIN command of the router did not return
1185 the channel key, added check for this. Affected file is
1188 * Fixed a channel ID update bug in JOIN command reply. Do
1189 not directly upgrade the ID but call the function
1190 silc_idlist_replace_channel_id if the ID was changed.
1191 Affected file silcd/command_reply.c.
1193 * Fixed memory leaks from command calling if it would fail.
1194 Affected file silcd/command.c.
1196 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Applied patches from cras:
1200 Memory leak fixes around libaries, irssi window resize fix,
1201 new silclist.h and silcdlist.h, all extern inline changed to
1204 * Removed dotconf from lib/dotconf, not needed anymore.
1206 * Removed TRQ from lib/trq, not needed anymore.
1208 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1209 with server connections. Later this will be configurable
1210 in config file after new config file is done. Affected file
1213 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1215 * Fixed a crash in server related to channel announcements.
1216 Affected file silcd/server.c.
1218 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Fixed memory leaks in silc_server_create_new_channel*
1221 functions. Affected file silcd/server.c.
1223 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1224 which ID was changed. This way the router will send the
1225 user list for the channel again, and server won't be in
1226 desync in some rare circumstances. Affected file is
1227 silcd/packet_receive.c.
1229 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1231 * Check for NULL socket pointer in the function
1232 silc_server_packet_send_to_channel_real. Affected file
1233 silcd/packet_send.c.
1235 * Fixed the BAN notify handling to correctly remove ban
1236 list. Affected file silcd/packet_receive.c.
1238 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1240 * Fixed some header addition to Toolkit distribution in
1241 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1243 * Added lib/silcclient/client_ops_example.h as an template
1244 file for application programmers to quickly start using
1245 the SilcClientOperation functions in their application.
1246 Updated the lib/silcclient/README as well to tell about this
1247 nice file made available.
1249 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1251 * Call silc_server_remove_from_channels when removing client
1252 entry when NO_SUCH_CLIENT_ID was received. Affected file
1253 is silcd/command_reply.c.
1255 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1257 * Added server & router operator statistics updating. Affected
1258 file silcd/packet_receive.c and silcd/command.c.
1260 * Fixed the SERVER_SIGNOFF notify handling on normal server
1261 not to save the history information for clients. Same was
1262 fixed earlier in remove_clients_by_server function, but not
1263 here. Affected file silcd/packet_receive.c.
1265 * Raised the default connection-retry count from 4 to 7 in
1266 server. Affected file silcd/server.h.
1268 * Cancel any possible reconnect timeouts when we start the
1269 key exchange. Affected file silcd/server.c.
1271 * Do not reconnect on connection failure when SCONNECT was
1272 given. Affected files silcd/server.[ch].
1274 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1276 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1278 * Fixed the NICK command to always give the unformatted
1279 nickname to the one giving the NICK command. If unformatted
1280 nickname is cached already it will be formatted and the
1281 local entry will always get the unformatted nickname.
1282 Affected file lib/silcclient/idlist.c.
1284 * Fixed some double frees from client library commands.
1285 Affected file is lib/silcclient/command.c.
1287 * Fixed CUMODE command in server to assure that no one can
1288 change founder's mode than the founder itself, there was a
1289 little bug. Affected file silcd/command.c.
1291 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1293 * Removed the SilcClientCommandDestructor from the client
1294 libary, it is not needed anymore. Affected files are
1295 lib/silcclient/silcapi.h, command[_reply].[ch],
1296 client_notify, idlist.c.
1298 * Fixed GETKEY command to first resolve client, and then
1299 resolve the server only if the client was not found, instead
1300 of resolving both at the same time. Affected file is
1301 lib/silcclient/command.c.
1303 * Added silc_client_start_key_exchange_cb and lookup the
1304 remote hostname and IP address before starting the key
1305 exchange with server. The affected file is
1306 lib/silcclient/client.c.
1308 * The server's public key is now saved using the IP address
1309 of the server and not the servername for the filename.
1310 The hostname public key filename is checked as an fall back
1311 method if the IP address based filename is not found.
1313 Fixed the GETKEY command to save the fetched server key
1314 in correct filename.
1316 Print the remote server's hostname now when new key is
1317 received during connection process. Affected file is
1318 irssi/src/silc/core/client_ops.c.
1320 * Return always our own public key to the client if it asks
1321 for it with GETKEY command. Affected file silcd/command.c.
1323 * Removed the use_auto_addr variable from default config
1324 file since it was in wrong section. Affected file is
1327 * Fixed TOPIC_CHANGE notification to not route it when it
1328 was sent using silc_server_send_notify_to_channel function.
1329 Affected file silcd/command.c.
1331 * Fixed silc_server_send_notify_kicked to send the kicker's
1332 Client ID also, it was missing. Affected files are
1333 silcd/command.c, silcd/packet_send.[ch].
1335 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1337 * Do not save client history information in SERVER_SIGNOFF.
1338 Fixes the bug in normal server that it does not detect
1339 the client becoming valid after the server becomes back
1340 online. Affected file silcd/server_util.c.
1342 * Added `sock_error' field into the SilcSocketConnection
1343 context. When error occurs during socket operation (read
1344 or write) the error is saved. Added also new function
1345 silc_socket_get_error to return human readable socket error
1346 message. Affected files are lib/silcutil/silcsockconn.[ch],
1347 lib/silcutil/unix/silcunixsockconn.c, and
1348 lib/silcutil/win32/silcwin32sockconn.c.
1350 * The server now prints the socket error message in the
1351 signoff for client. Affected file silcd/server.c.
1353 * Fixed the `created' channel information sending from router
1354 to server in JOIN command. Checks now whether the channel
1355 really was created or not and set it according that.
1357 Fixed the JOIN command to use the client entry's current
1358 ID during the joining procedure instead of the one it sent
1359 in the command (it is checked though), since it can change
1360 between the packet processing and command processing, and
1361 would just case unnecessary pain in the client end. Affected
1362 file silcd/command.c.
1364 * Fixed a channel key payload sending to use correct channel
1365 ID when the server was forced to change the channel's ID by
1366 router. Router sent the key payload with the old Channel ID.
1367 Affected file silcd/packet_receive.c.
1369 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1371 * Call silc_server_save_channel_key only if the key payload
1372 was provided in the JOIN command's command reply. Affected
1373 file silcd/command_reply.c.
1375 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1377 * Fixed silc_mp_sizeinbase to return the value correctly with
1378 MPI. Affected file lib/silcmath/mp_mpi.c.
1380 * Fixed the stop_server signal to correctly stop the scheduler
1381 and gracefully stop the server when SIGTERM or SIGINT signals
1382 are received. Affected file silcd/silcd.c.
1384 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1386 * Simple handling of TERM and HUP signals. Also added some log
1387 flushing call around. Affected file is
1390 * Fixed small bugs in silclog.c. Now buffering output will take
1391 effect after 10 seconds since startup: This will ensure that
1392 no important startup messages are lost. Also output redirection
1393 will preserve original format ([Date] [Type] message).
1394 Affected file is lib/silcutil/silclog.c.
1396 * Added two options to the config file, in the logging section:
1397 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1398 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1400 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1402 * Do not print the warning about log files not being initialized
1403 more than once to avoid excess logging. Affected file is
1404 lib/silcutil/silclog.c.
1406 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1407 the SIM copying in make install in Makefile.am.pre.
1409 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1411 * Rewritten silclog APIs. Globally interesting changes follows:
1412 silc_log_set_files() changed to silc_log_set_file().
1413 silc_log_set_callbacks() changed to silc_log_set_callback().
1414 ROBOdoc documented silclog header file.
1415 SilcLogCb now returns bool to wether inihibit the default
1416 handler or not (to keep the old behaviour return always TRUE).
1417 The new APIs should also fix the problem of the
1418 silcd_error.log file that was written in the current directory.
1421 Log files streams will remain opened after silc_log_set_file()
1422 call, means less CPU usage notably on high traffic servers.
1423 File streams are now full buffered, and flushed to the disk
1424 every 5 minutes, lesses HD activity and CPU usage.
1425 Messages can be redirected, allowing admins to configure
1426 one single logfile for all server messages.
1427 the silc_log_quick global variable to activate fast-logging.
1428 Affected files lib/silcutil/silclog.[ch]
1430 * Changed some code to conform new silclog APIs. Affected
1431 files are doc/example_silcd.conf.in, silcd/server.c
1432 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1435 * Fixed a memory leak that could occur in some situations.
1436 Affected file silcd/serverconfig.c.
1438 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1440 * Added the silc_client_del_client to remove the client from
1441 all channels as well. Affected file lib/silcclient/idlist.c.
1443 * Fixed the client library to correctly remove the client
1444 from all channels when the client entry is being destroyed.
1445 Affected file lib/silcclient/client_notify.c, command.c.
1447 * Added auto-nicking support to the client library. If the
1448 applicatio now sets client->nickname it will be sent to the
1449 server after connecting by the library. This way for example
1450 SILCNICK (or IRCNICK) environment variables will have effect
1451 and always change the nickname automatically to whatever
1452 it is wanted. Affected file lib/silcclient/client.[ch].
1454 * Renamed silc_server_command_bad_chars to the
1455 silc_server_name_bad_chars and moved it to the
1456 silcd/server_util.[ch]. Added also new function
1457 silc_server_name_modify_bad to return nickname that
1458 includes bad characters as new nickname without those
1459 bad characters. This check and modify is now used in
1460 silc_server_new_client when the username is initially set
1461 as nickname, so it must be checked to be valid nickname.
1462 Affected file silcd/packet_receive.c.
1464 * The nickname length is now taken from the packet for real
1465 and not trusted to strlen() since it clearly can return
1466 wrong length for nickname including bad characters. This
1467 also applies to channel names. Affected file silcd/command.c.
1469 * Removed the lib/silcsilm/modules directory. Modules are now
1470 compiled into the lib/silcsim. Fixed the copying of the
1471 modules to follow symbolic links in Makefile.am.pre.
1473 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1475 * Fixed silc_string_regexify list creation. Fixes bugs with
1476 BAN and INVITE commands in server. The affected file is
1477 lib/silcutil/unix/silcunixutil.c.
1479 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Removed the command destructor entirely from the server's
1482 command and command reply routines. It is not needed, and
1483 its usage was buggy and caused crashes. Affected files are
1484 silcd/command[_reply].[ch].
1486 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Cancel protocol and NULL sock->protocol if timeout
1489 occurred during protocol. Affected file silcd/server.c.
1491 * Cancel protocol timeouts always before calling the final
1492 callback, to assure that after final callback is called
1493 no other state will be called for the protocol anymore.
1494 Affected file silcd/protocol.c.
1496 * Print error log if incoming connection configuration could
1497 not be found. Affected file silcd/server.c.
1499 * Fixed JOIN command to correctly save the founder mode
1500 to the client on normal SILC server, when the channel
1501 was created by the router. Affected file silcd/command.c.
1503 * Fixed LIST command (hopefully) to send correct reply
1504 packets. Affected file silcd/command.c.
1506 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * The silc_packet_receive_process now returns FALSE if the
1509 read data was invalid packet, and TRUE if it was ok.
1511 The server now checks that if unauthenticated connection
1512 sends data and its processing fails the server will close
1513 the connection since it could be a malicious flooder.
1515 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1517 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Make sure the warning about error opening a log file is
1520 printed only once and not everytime it fails (produces
1521 too much useless log). Affected file lib/silcutil/silclog.c.
1523 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1525 * Made the silc_server_daemonise() function more readable.
1526 Affected file silcd/server.c.
1528 * Pid file is now optional, the user may comment it out from
1529 the config file. Removed define SILC_SERVER_PID_FILE, we
1530 don't need a default any longer. Affected file
1531 configure.in.pre, lib/Makefile.am.pre.
1533 * Make some use of the pid file. The server now dies at startup
1534 if it detects a valid pid file on his path. The server would
1535 die anyway in this circumstance, because of the bind() failure.
1536 Affected file silcd/silcd.c.
1538 * No longer compiling lib/dotconf.
1540 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Fixed JOIN command parsing not to crash. Affected file
1543 lib/silcclient/command.c.
1545 * Fied the NICK_CHANGE notify to add the new client entry
1546 even it is resolved. This removes an <[unknown]> nick
1547 thingy bug in the client. Affected file is
1548 lib/silcclient/client_notify.c.
1550 * Do not try to allocate 0 bytes (efence does not like it)
1551 in lib/silccore/silccomand.c when encoding payload.
1553 * Do not take IRCNICK as nickname in Irssi SILC client since
1554 it is not possible to set nickname before hand connecting
1555 the server (TODO has an entry about adding auto-nicking
1558 * Changed the silc_server_command_pending to check whether
1559 there already exists an pending entry with the specified
1560 command, command identifier and pending callback. This is
1561 to fix IDENTIFY and WHOIS related crashes that may register
1562 multiple pending commands with same identifier. Affected
1563 file silcd/command.c.
1565 * Fixed the server to reconnect to the router even if it
1566 was already reconnecting and EOF was received. This to
1567 fix a possibility that the server wouldn't ever try to
1568 auto-reconnect to the router. Affected file silcd/server.c.
1570 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Fixed the server's password authentication to use the
1573 length of the locally saved password, and not the one
1574 sent in the packet. Affected file silcd/protocol.c.
1576 * Fixed same password authentication problem in the
1577 Authentication Payload handling routines in
1578 lib/silccore/silcauth.c.
1580 * Yet another password authentication problem fixed with
1581 channel password handling in silcd/command.c.
1583 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * If first character of string in silc_parse_userfqdn is '@'
1586 then do not parse it. Affected file is
1587 lib/silcutil/silcutil.c.
1589 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Fixed minor bug in IDENTIFY command reply sending, which
1592 caused various weird problems during JOIN when it was
1593 resolving names for users. Affected file silcd/command.c.
1595 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Fixed the IDENTIFY command reply sending to chech better valid
1598 clients. It was possible to send incomplete list of replies.
1599 Affected file silcd/command.c.
1601 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Added silc_client_command[s]_[un]register functions now to
1604 dynamically register the commands in client library. Removed
1605 the static table of commands. This allows the client library
1606 to call commands without causing the application to know about
1607 what commands library has called.
1609 Removed the INFO command reply kludge to detect when the command
1610 was called by library. Now library use its own command reply
1611 function for INFO command.
1613 Added function silc_client_command_call to call a command.
1614 Application can use it to call command, not access the structure
1617 Now all commands that are sent by the client library (not
1618 explicitly sent by application) use own command reply functions.
1620 Affected files around lib/silcclient/ and in
1621 irssi/src/silc/core/.
1623 * Fixed the WHOIS command reply sending to chech better valid
1624 clients. It was possible to send incomplete list of replies.
1626 Fixed the WHOIS and IDENTIFY to send the request to router
1627 if normal server did not do it and did not find any results.
1629 Affected file silcd/command.c.
1631 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * Moved the internal data from SilcClient context into its
1634 own file, not accesible to application. Affected files
1635 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1636 and other files in client library.
1638 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Added doc/examples installation target in Makefile.am.pre.
1643 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1645 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1646 commands the found client entry will be removed from the
1647 cache, after notifying application about the error. Affected
1648 file lib/silcclient/command_reply.c.
1650 * Changed the /MSG to check for exact nickname user gave, and
1651 not let `nick' match `nick@host' if it is only one found. Now,
1652 user must type the exact nickname (like nick@host2) even if
1653 there are no more than one same nicks found. This is to avoid
1654 a possibility of sending nickname to wrong nickname since
1655 `nick' could match `nick@host'. Affected file is
1656 irssi/src/core/silc-servers.c.
1658 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * Do not print "you are now server operator" or similar when
1661 giving /away command. Affected files are
1662 irssi/src/silc/core/client_ops.c, silc-servers.h.
1664 * Made the silc_server_command_pending_error_check to send
1665 the same command reply payload it received back to the
1666 original sender of the command. This way all arguments
1667 that was received by the server will be received by the
1668 client too. Affected file silcd/command.c.
1670 * Added the silc_idcache_add to return the created cache entry
1671 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1673 * Add global clients to expire if they are not on any channel.
1674 This is because normal server will never know if they signoff
1675 if they are not on any channel. The cache expiry will take
1676 case of these entries. This is done by normal servers only.
1677 The affected files are silcd/command_reply.c,
1678 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1680 * If server receives invalid ID notification for WHOIS or
1681 IDENTIFY and the ID exists in the lists, it is removed.
1682 Affected file silcd/command_reply.c.
1684 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1685 in client then client entry that it matches is searched and
1686 the nickname is printed on the screen for user. Affected
1687 file irssi/src/silc/core/client_ops.c.
1689 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1691 * Use cache entry expire time in the LIST command reply to
1692 purge old entries from the cache after the LIST command
1693 reply has been received. This way we don't have non-existent
1694 entries in the cache for too long. Affected file is
1695 silcd/command_reply.c.
1697 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * If we are normal server, and we've not resolved client info
1700 in WHOIS or IDENTIFY from router, and it is global client,
1701 we'll check whether it is on some channel. If it is not
1702 then we cannot be sure about its validity and will resolve it
1703 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1704 file silcd/command.c.
1706 * Search channel by name (if possible) rather than by ID
1707 in IDENTIFY command's command reply. Affected file is
1708 silcd/command_reply.c.
1710 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1713 Updated specs and implemented it. Affected file silcd/command.c,
1714 silcd/packet_send.c and silcd/packet_receive.c.
1716 * Implemented the <founder auth> payload handling in the JOIN
1717 command. If provided all conditions for channel joining
1718 except requirement to provide correct passphrase can be
1719 overrided by the channel founder. Updated the protocol specs.
1720 Affected file silcd/command.c.
1722 Added support for founder auth in JOIN command in client
1723 library. Fixed the parsing of the JOIN command now to support
1724 all options as they should be. The affected file is
1725 lib/silcclient/command.c.
1727 * Optimized the WHOIS and IDENTIFY commands to send the request
1728 to router only if it includes nicknames or other names. If
1729 they include only IDs then check the local cache first before
1730 routing. Affected file is silcd/command.c.
1732 * Added channels topic announcements. Affected file is
1733 silcd/packet_receive.c and silcd/server.c.
1735 * Fixed the silc_server_send_notify_topic_set to really destine
1736 the packet to channel. Affected file silcd/packet_send.c.
1738 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1739 library. Affected file lib/silcclient/client_notify.c.
1741 * Added UMODE announcements. Affected file silcd/server.c.
1743 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Memory leak fixes in:
1747 lib/silcutil/silcsockconn.c
1748 lib/silcske/silcske.c
1749 lib/silcske/groups.c
1751 lib/silccrypt/silcpkcs.c
1752 lib/silccore/silccommand.c
1753 lib/silccore/silcidcache.c
1758 * ROBOdoc documented the lib/silcske/groups.h file and a
1759 bit changed the interface for better.
1761 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1763 * Update the client entry context in the ID cache after
1764 nick change. Affected file lib/silcclient/command.c.
1765 Fixes the CUMODE command when regaining founder privileges,
1766 and a little WHOIS problem.
1768 * Fixed silc_net_gethostbyname to correctly call the
1769 inet_ntop. Affected file lib/silcutil/silcnet.c.
1771 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1773 * Added IPv6 support checking to the configure.in.pre, added
1774 also --enable-ipv6 option to override the check. Affected
1775 file configure.in.pre.
1777 * The silc_thread_create now calls the start function
1778 directly if threads support is not compiled in. Removes
1779 ugly #ifdef's from generic code. Affected files are
1780 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1782 * Added silc_net_gethostby[name/addr]_async to asynchronously
1783 resolve. Affected files are lib/silcutil/silcnet.[ch].
1785 * Added support for rendering IPv6 based server, client and
1786 channel IDs. Affected file lib/silcutil/silcutil.c.
1788 * Added support for creating IPv6 based server IDs. Affected
1789 file is silcd/serverid.c.
1791 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1793 * Added silc_net_gethostby[addr/name] into the
1794 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1795 routines. Added silc_net_is_ip[4/6]. Affected file is
1796 lib/silcutil/unix/silcunixnet.c. All routines that take
1797 address as argument now supports both IPv4 and IPv6 addresses.
1799 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1801 * Fixed LIST command reply sending in server. Affected file
1804 * Server now sends the kicker's client ID in the KICK notify
1805 to the kicked client. Affected file silcd/command.c.
1807 * The client library now parses the kickers client ID and
1808 UI displays it. Affected files lib/silcclient/client_notify.c
1809 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1811 * Made all payload parsing function prototypes consistent.
1812 They all take now const unsigned char * and uint32 pair as
1813 the payload data instead of SilcBuffer. Changes all around
1814 the source tree. Other unsigned char* -> const unsigned char*
1815 changes around the tree as well.
1817 * Optimized SFTP client and server packet sending not to
1818 allocate new buffer for each packet but to recycle the
1819 first allocated buffer. Affected files are
1820 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1822 * Optimized the SFTP client to use SilcList instead of
1823 SilcDList for requests, because it is faster. Affected file
1824 is lib/silcsftp/sftp_client.c.
1826 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1827 into lib/silccore/silcid.[ch].
1829 Renamed silcpayload.[ch] into silcargument.[ch].
1831 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * If client entry is deleted with active key agreement
1834 session, abort the session.
1836 The silc_client_abort_key_agreement now calls the completion
1837 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1839 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1842 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Don't use __restrict in older GCC's. Affected file is
1845 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1847 * silc_net_localhost now attempts to reverse lookup the
1848 IP/hostname. Affected file lib/silcutil/silcnet.c.
1850 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1851 command. It can be used to gain founder privileges at
1852 the same time when joining the channel.
1854 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1855 kicker's client ID as well. Updated protocol specs.
1857 Defined that the server must send SILC_COMMAND_IDENTIFY
1858 command reply with error status to client who sent
1859 private message with invalid client ID.
1861 Updated the protocol specification.
1863 * Added silc_server_send_command_reply to send any
1864 command reply. Affected file silcd/packet_send.[ch].
1866 * Added silc_id_payload_encode_data to encode ID payload
1867 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1869 * The server now send IDENTIFY command reply with error
1870 status if client ID in private message is invalid. Affected
1871 file silcd/packet_receive.c.
1873 * Save the server key file with server's IP address in
1874 the filename instead of hostname. The affected file is
1875 irssi/src/silc/core/client_ops.c.
1877 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1882 * Added libtool support for compiling shared objects in
1883 lib/silcsim. Affected file configure.in.pre and
1884 lib/silcsim/Makefile.am. Original patch by cras.
1886 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Pid file configuration, and server's config file fixes
1889 patch by toma. Updated CREDITS file.
1891 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Fixed silc_client_channel_message to not try to decrypt
1894 the message twice if it resolved the destination client
1895 information. This could cause of dropping one channel
1896 message. Affected file lib/silcclient/client_channel.c.
1898 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1901 lib/silcclient/client.c. This function is used when the SILC
1902 Client is run under some other scheduler, or event loop or
1903 main loop. On GUI applications, for example this may be
1904 desired to used to run the client under the GUI application's
1905 main loop. Typically the GUI application would register an
1906 idle task that calls this function multiple times in a second
1907 to quickly process the SILC specific data.
1909 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1911 * Fixed silc_server_drop() for dropping the supplementary
1912 groups as well, this could cause a security hole on some
1915 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1920 * Write PID file after dropping privileges. Added -F option
1921 to run server on foreground. A patch by debolaz.
1922 Affected files silcd/server.c, silcd/silcd.c.
1924 * Fixed MOTD to return the MOTD file server name. Affected
1925 file silcd/command.c.
1927 * Added INFO command reply handling to the Irssi SILC Client.
1928 Affected file irssi/src/silc/core/client_ops.c.
1930 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Fixed the silc_idcache_list_* routines to really support
1933 the dynamic list. Fixes a crash. Affected file is
1934 lib/silccore/silcidcache.c.
1936 * Fixed the LIST command reply to really call LIST command's
1937 pending callbacks. Affected file silcd/command_reply.c.
1939 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Update conn->local_entry->nickname after giving NICK
1942 command. Affected file lib/silcclient/command.c.
1944 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1946 * Added the [pid] option to the silcd configuration file
1948 Affected files: serverconfig.[ch] and silcd.c
1950 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Save fingerprint in WHOIS command reply in server.
1953 Affected file silcd/command_reply.c.
1955 * Fixed NICK commands pending callback registration.
1956 Affected file lib/silcclient/command.c.
1958 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1960 * Use ++server->cmd_ident when sending commands in server,
1961 instead of random number. Affected file silcd/command.c.
1963 * Fixed GETKEY command reply to call actually GETKEY pending
1964 command callbacks. Affected file silcd/command_reply.c.
1966 * A bit stricter check for nicknames. Check for same nickname
1967 in NICK command also. Affected file silcd/command.c.
1969 * Do not call INFO command everytime client ID changes, only
1970 during first connecting. Affected file lib/silcclient/client.c.
1972 * Set the new nickname only after successful command reply for
1973 NICK command is returned by server. Affected file
1974 lib/silcclient/command.c.
1976 * Remove nicknames from nicklist during server_signoff notify.
1977 Should fix /NAMES bit more. The affected file is
1978 irssi/src/silc/core/silc-channels.c.
1980 * Added `fingerprint' field to the SilcIDListData in the
1981 silcd/idlist.h to hold the fingerprint of the client's
1984 Send the fingerprint of the client's public key in WHOIS
1987 Affected files silcd/command.c, and silcd/idlist.[ch].
1989 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1990 create fingerprint from given data.
1992 * Show the fingerprint of the client's public key in WHOIS.
1993 Affected files irssi/src/module-formats.[ch] and
1994 irssi/src/silc/core/client_ops.c.
1996 * Format the multiple same nicknames also during JOIN and
1997 NICK_CHANGE notifys. Affected file is
1998 lib/silcclient/client_notify.c.
2000 * Do not print error on screen for invalid private message
2001 payload since it can come if someone is sending private
2002 messages with wrong key. Affected file
2003 lib/silccore/silcprivate.c.
2005 * Fixed multiple concurrent /PING crash. Affected file
2006 lib/silcclient/command.c.
2008 * Changed the wrong ID encoding. All IP addresses must be
2009 in MSB first order in encoded format. They were encoded
2010 wrong and was in LSB format. Affected files are
2011 silcd/serverid.c, lib/silcutil/silcutil.c.
2013 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2015 * Call the `connect' client operation through the scheduler
2016 in case of error. Affected file lib/silcclient/client.c.
2018 * Call the `failure' client operation even if the error
2019 occurred locally during a protocol. Affected file is
2020 lib/silcclient/protocol.c.
2022 * Added support of sending LIST command to router from normal
2023 server. This way normal server can get list of all channels
2024 in the network too. Fixed the channel list sending in the
2025 server too. Affected files are silcd/command.c, and
2026 silcd/command_reply.[ch].
2028 * Added silc_server_update_channels_by_server and
2029 silc_server_remove_channels_by_server. They are used during
2030 disconnection of primary router and in backup router protocol.
2031 Affected file silcd/server_util.[ch], silcd/server.c and
2032 silcd/server_backup.c.
2034 * Fixed channel adding to global list in IDENTIFY command
2035 reply in server. Affected file silcd/command_reply.c.
2037 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * If the incoming packet type is REKEY or REKEY_DONE process
2040 that packet always synchronously. Fixes yet another MAC
2041 failed error on slow (dialup) connections. Affected file
2042 lib/silcclient/client.c and silcd/server.c.
2044 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Call check_version SKE callback for initiator too. Affected
2047 file lib/silcske/silcske.c.
2049 * Implemented fix for security hole found in the SKE that was
2050 fixed in the specification few days back; the initiator's
2051 public key is now added to the HASH value computation.
2052 Added backwards support for the old way of doing it too, for
2053 old clients and old servers. Affected file is
2054 lib/silcske/silcske.c.
2056 * Enabled mutual authentication by default in SKE. If initiator
2057 is not providing mutual authentication the responder will
2058 force it. This will provide the proof of posession of the
2059 private key for responder. The affected files are
2060 lib/silcclient/protocol.c and silcd/protocol.c.
2062 * Do not cache anymore the server's public key during SKE.
2063 We do mutual authentication so the proof of posession of
2064 private key is done, and if the server is authenticated in
2065 conn auth protocol with public key we must have the public
2066 key already. Affected file silcd/protocol.c.
2068 * Added new global debug variable: silc_debug_hexdump. If
2069 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2070 file lib/silcutil/silclog.[ch].
2072 * Fixed compilation warning due to char * -> const char *.
2073 Affected files lib/silcutil/silcnet.h, and
2074 lib/silccore/silcauth.[ch].
2076 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Fixed CMODE command when new channel key was created. If
2079 the creation failed the old key was removed. Next time giving
2080 same command would crash the server since the old key was
2081 freed already. Affected file silcd/command.c.
2083 * Fixed the silc_server_announce_get_channels to not crash
2084 on reconnect. Affected file silcd/server.c.
2086 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Added silc_log_set_debug_string function to set a regex
2089 string to match for debug output. Only the function names,
2090 or filenames matching the given debug string is actually
2091 printed. This way it is possible to filter out those debug
2092 strings that user is not interested in.
2094 Fixed a bug in silc_string_regexify.
2096 Affected files lib/silcutil/silclog.[ch], and
2097 lib/silcutil/unix/silcunixutil.c.
2099 * Changed the -d options in both server and Irssi SILC client
2100 to take the debug string as argument. Affected files
2101 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2103 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Added silc_hash_babbleprint to create a Bubble Babble
2106 Encoded fingerprint. The encoding is developed by Antti
2107 Huima (draft-huima-babble-01.txt), and it creates human
2108 readable strings out of binary data. Affected file
2109 lib/silccrypt/silchash.[ch].
2111 * Print the babble print now in addition of fingerprint as well
2112 in Irssi SILC client. Affected files are
2113 irssi/src/fe-common/silc/module-formats.[ch],

2116 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Fixed a security problem found in SKE. The initiator's
2119 public key too is now added to the HASH hash value creation
2120 which is signed by the responder to create the SIGN value.
2121 This will prevent anyone in the middle to lie to the responder
2122 about the initiator's public key. If this is done now, the
2123 man in the middle will get caught. Updated the protocol
2126 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Better installation directory handling. Configure module
2129 paths and other paths automatically to example_silc* files
2130 in doc/. A patch by toma.
2132 * Fixed compiler warning from MPI library, and from SILC RNG.
2135 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2136 It can be configured with ./configure. A patch by toma.
2138 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Find correct make to use in prepare-clean. A patch by
2141 toma. Affected file prepare-clean.

2160 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Added silc_pkcs_public_key_compare to compare two
2163 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2165 * Check that the client who set the founder mode on the
2166 channel is the same client that is giving the founder
2167 mode to itself. It is done by comparing the saved public
2168 key (it is saved even in the authentication is passphrase).

2176 * Process the DISCONNECT packet through scheduler in the
2177 client library. Affected file lib/silcclient/client.c.
2179 * Fixed the silc_client_packet_parse to not to increase
2180 the packet sequence number if the conn->sock and the
2181 current socket connection is not same. This can happen
2182 for example during key agreement when the conn includes
2183 multiple socket connections (listeners). Affected file
2184 lib/silcclient/client.c.
2186 * The sender of the file transfer request now provides also
2187 the pointer (listener) for the key exchange protocol. If
2188 the listener cannot be created then it sends empty key
2189 agreement and lets the receiver provide the listener.
2191 Added `local_ip' and `local_port' arguments to the
2192 silc_client_file_send. If they are provided they are used,
2193 if not then it will attempt to find local IP address, if
2194 not found or bind fails then the remote client will provide
2197 Affected files are lib/silcclient/client_ftp.c and
2198 lib/silcclient/silcapi.h.
2200 * Extended the FILE SEND command to support defining the
2201 local IP and port for key exchange listener. They are

2206 * Defined to WHOIS command reply the sending of fingerprint
2207 of the client's public key (if the proof of posession of the
2208 corresponding private key is verified by the server).
2209 Updated to the protocol specification.
2211 * Added support of receiving the client's public key's
2212 fingerprint in command reply in client library. Affected
2213 file is lib/silcclient/command_reply.c, and
2214 lib/silcclient/idlist.[ch].
2216 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2273 preserve the WHOWAS info for the client. Affected file
2274 silcd/server_util.c.
2276 * Fixed SERVER_SIGNOFF notify handling in the server. The
2277 server is now able to process incoming SERVER_SIGNOFF notify
2278 for a server that it doesn't even know about. It will remove
2279 the clients provided in the notify. Affected file
2280 silcd/packet_receive.c.
2282 * Check for partial packet in data queue after every packet that
2283 was found from the queue. Return and wait for more data if
2284 there is partial data in queue. Affected file is
2285 lib/silccore/silcpacket.c.
2287 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Added SilcClietFileError enum to indicate error in
2290 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

2302 irssi/src/fe-common/silc/module-formats.[ch].
2304 * Wrote a help file for FILE command.
2306 * Added silc_rng_global_get_byte_fast to get not-so-secure
2307 random data as fast as possible. Random data is read from
2308 /dev/urandom if available and from the SILC RNG if not
2309 available. It is used in padding generation. Affected file
2310 lib/silccrypt/silcrng.[ch].
2312 * All packets in client library are now processed synchronously.
2313 Optimized packet processing a lot. Affected file
2314 lib/silcclient/client.c.
2316 * All server connection packets are processing synchronously
2317 now in server, to optimize packet processing. Affected file
2320 * Include files are installed now only in Toolkit distribution
2321 if make install is given. Affected files: all Makefile.am's.
2323 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Assure that silc_client_notify_by_server_resolve does not
2326 resolve the client information multiple times. If it cannot
2327 be found by the first it cannot be found at all. Affected
2328 file lib/silcclient/client_notify.c.
2330 * Fixed WHOWAS command reply calling. Affected file
2331 lib/silcclient/command_reply.c.
2333 * Removed all references to silc_idlist_get_client from the
2334 Irssi SILC client since that call is internal call used by
2335 the library. The Irssi SILC client will use now client
2336 retrieval functions found in silcapi.h.
2338 * Fixed a bug in resolving nickname info before sending
2339 private message. It used freed memory. Affected file
2340 irssi/src/silc/core/silc-servers.c.
2342 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Assure my_channels statistics cannot go negative in server.
2345 Affected files silcd/server.c, silcd/server_util.c.

2361 * Added silc_net_localip to return local host's IP address.
2362 Affected file lib/silcutil/silcnet.[ch].
2364 * If key exchange or rekey protocol is active for a connection
2365 parse all packets syncronously since there might be packets
2366 in packet queue that we are not able to process without first
2367 processing packets before them. Affected file silcd/server,
2368 lib/silcclient/client.c.
2370 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2371 whether library should continue processing the packet.
2372 Affected file lib/silccore/silcpacket.h.
2374 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2418 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2419 is incomplete and is being resolved, it won't be resolved
2422 Make sure also that USERS command reply does not resolve
2423 twice information. Affected file is
2424 lib/silcclient/command_reply.c.
2426 Make sure that silc_client_get_clients_by_list does not
2427 resolve twice same information.
2429 * Check for valid client->id in the silc_server_free_client_data.
2430 Affected file silcd/server.c.
2432 * Fixed /GETKEY nick@server not to crash if the server entry
2433 is not found. Affected file lib/silcclient/command.c.
2435 * Fixed the silc_server_check_cmode_rights to check the

2445 * Call the silc_server_udpate_servers_by_server in the
2446 primary router that comes back online in the backup resuming
2447 protocol. Otherwise it routes packets wrong. Affected file
2448 silcd/server_util.[ch], silcd/server_backup.c.
2450 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2453 lib/silcutil/silcbuffmt.[ch].
2455 * Redefined the SILC packet header to include the padding
2456 length. Affected file lib/silccore/silcpacket.[ch].
2458 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2459 length for maximum padding up to 128 bytes). Affected
2460 file lib/silccore/silcpacket.h.
2462 * Removed all backwards support for old 0.5.x MAC thingies.
2463 The SILC packet header change makes it impossible to be
2464 backwards compatible.
2466 * Send the ENDING packet with timeout in the backup resuming
2467 protocol. This is to assure that all routers has connected
2468 to the primary router. Affected file silcd/server_backup.c.
2470 * Changed the RNG to take the first IV from random data. It
2471 used to take it from zero actually. Changed the RNG also
2472 to use /dev/urandom during session. /dev/random is used
2473 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2475 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Changed the SILC packet header to have the first two bytes
2478 (the packet length) encrypted. Affected files aroung the
2479 code tree, lib/silccore/silcpacket.[ch]. Removed the
2480 SilcPacketCheckDecrypt callback. It is not needed anymore
2481 since the silc_packet_receive_process will determine now
2482 whether the packet is normal or special.
2484 * Implemented the unidirectional MAC keys. Affected files
2485 lib/silcske/silcske.c, silcd/protocol.c and
2486 lib/silcclient/protocol.c.

2493 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Allow backup router to announce servers. All servers
2496 announced by backup router are added to the global list
2497 automatically. Update hte server's socket to our primary
2498 router also when backup router announces a server.
2499 Affected file silcd/packet_receive.c.
2501 * Do not update the client->router in the function
2502 silc_server_udpate_clients_by_server if the client is on
2503 global list. We might fail to find any specific server
2504 for locally connected clients and local cell clients. They
2505 should still use the `from' and not `to' as client->router.
2506 This fixes backup router resuming protocol. Affected file
2507 silcd/server_util.c.
2509 * Decrease channel statistics count only if the channel
2510 deletion worked. Affected files are silcd/server.c and
2511 silcd/server_util.c.
2513 * Added silc_server_update_servers_by_server to update origin
2514 of all server entries. Used during backup router protocol.

2523 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Assure that router cannot reroute the same channel message
2526 to the sender. Affected file silcd/packet_receive.c.
2528 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2530 * Made better checks that the channel message is not sent
2531 to the router it came from. Affected file is
2532 silcd/packet_send.c. Fixed memory leak too.
2534 * Announce informations for incoming router connection, but
2535 only after checking if it is replaced by backup router.
2536 Affected file silcd/packet_receive.c.
2538 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Fixed the backup resuming protocol to work in multiple
2541 router environment. Affected file silcd/server_backup.c.
2543 * Route packet only to one router in the function
2544 silc_server_packet_send_to_channel. Affected file is
2545 silcd/packet_send.c.
2547 * Fixed silc_server_send_notify_dest to set the broadcast
2548 flag. Fixed the silc_server_send_notify_topic to actually
2549 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2550 Affected file silcd/packet_send.c.
2552 * Changed the SFTP Filesystem interface. Changed the
2553 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2554 the filesystem operation function. The SilcSFTPFilesystem
2555 is now a context that is allocated by all filesystem allocation
2556 functions and it already includes the operations structure
2557 and filesystem specific context. It is given as argument
2558 now to the silc_sftp_server_start. This made the interface
2559 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2560 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2562 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Changed the backup router adding and getting interfaces
2565 in the server. The router that will be replaced by the
2566 specified backup router is now sent as argument. Affected
2567 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2570 * Added silc_net_addr2bin_ne to return the binary form of
2571 the IP address in network byte order. Affected files
2572 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2574 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Check for existing server ID in silc_server_new_server
2577 and in silc_server_connect_to_router_final and remove the
2578 old entry if it exists. Affected file silcd/packet_receive.c,
2581 * Send the channel message always to only one router, either
2582 in upstream or downstream. Affected file is
2583 silcd/packet_send.c.
2585 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Wrote the definition of the backup resuming protocol to the
2588 protocol specification.
2590 * Removed one redundant channel key generation from normal
2591 server during joining procedure. Removed one redundant
2592 channel key sending from server to router during joining
2593 procedure. Affected file silcd/command.c.
2595 * Made minor bugfixes to the backup router resuming protocol.
2596 Affected file silcd/server_backup.c, server.c.

2605 resume the primary router position in the cell after the
2606 primary router comes back online. Affected files
2607 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2608 and silcd/server_util.[ch].
2610 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * Sleep two (2) seconds after sending QUIT command to server.
2613 Affected file lib/silcclient/command.c.
2615 * Assure that if outgoing data buffer is pending do not force
2616 send any data. Affected file silcd/packet_send.c.
2618 * Assure that if outgoing data buffer is pending do not force
2619 send any data. Affected file lib/silcclient/client.c.
2621 * Implemented the backup router support when the primary router
2622 goes down. The servers and routers can now use the backup
2623 router as new primary router without loosing connectivity.
2625 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2627 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2628 in the server to indicate disabled entry. All data read
2629 from the connection will be ignored and no data is sent
2630 for entry that is disabled. Affected files are
2631 silcd/idlist.h, silcd/server.c.
2633 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2635 * Created SFTP client and server test programs in the
2636 lib/silcsftp/tests directory.
2638 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Implemented memory filesystem (virtual filesystem) for
2641 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2644 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Implemented the SFTP (SSH File Transfer Protocol) to the
2647 lib/silcsftp. It includes SFTP client and SFTP server
2650 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Moved lib/silccore/silcprotocol.[ch] to the
2653 lib/silcutil library.
2655 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2656 take variable argument list pointer as argument. Affected
2657 file lib/silcutil/silcbuffmt.[ch].
2659 * Added silc_buffer_set function that is used to set data
2660 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2661 Affected file lib/silcutil/silcbuffer.h.
2663 * Changed various routines in the core library to use the new
2664 silc_buffer_set instead of allocating new buffer only for
2667 * Added 64-bit value formatting and unformatting support to the
2668 silc_buffer_[un]format routines. Affected file is
2669 lib/silcutil/silcbuffmt.[ch].
2671 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2672 to includes/bitmove.h.
2674 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2676 * Fixed channel user mode saving in client library. Affected
2677 file lib/silcclient/command[_reply].c.
2679 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * Defined the file transfer to the SILC Protocol. Added
2682 new packet type SILC_PACKET_FTP and defined File Transfer
2683 Payload. The mandatory file transfer protocol is SFTP
2684 (SSH File Transfer Protocol). Affected file in addition
2685 of the internet draft is lib/silccore/silcpacket.h.
2687 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2688 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2689 is used as part of backup router protocol when the primary
2690 router of the cell is back online and wishes to resume
2691 the position as primary router.
2693 * Redefined the MAC generation keys in the protocol. The
2694 same key is not used anymore in both direction. Both
2695 direction will now use different keys for sending and
2696 receiving. This fixes a potential security flaw. This
2697 change causes incompatibilities in the protocol.
2699 * Redefined also the MAC computation from the packet.
2700 An packet sequence number is now added to the MAC
2701 computation. This prevents possible replay attacks against
2702 the protocol. This change too causes incompatibilities
2705 Added `sequence' field to the SilcPacketContext to hold
2706 the current sequence number for the packet.
2708 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Added `created' field to the SilcIDListData in the file
2711 silcd/idlist.h to indicate the time when the entry was
2714 * Added `created' field to the SilcChannelEntry too. Affected
2715 file silcd/idlist.h.
2717 * Added `creation_time' aguments to all the announcement functions
2718 in the server. If it is provided then only the entries that
2719 was created after the provided time frame are actually
2720 announced. Affected file silcd/server.[ch].
2722 * The protocol says that the Channel ID's IP address must be
2723 based on the router's IP address. Added check for this in
2724 the silc_server_new_channel when processing incoming New Channel
2725 Payload. Affected file silcd/packet_receive.c.
2727 * Print out the correct version with --version in SILC client.
2728 Affected file irssi/src/silc/core/silc-core.c.
2730 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Fixed WHOWAS command to check for completnes of the client
2733 entry always, not just when the command is coming from client.
2734 Affected file silcd/command.c.
2736 * Added new function silc_server_packet_queue_purge to purge the
2737 outgoing data queue to the network. After the function returns
2738 it is guaranteed that the outgoing packet queue is empty.
2739 Affected file silcd/packet_send.[ch].
2741 * Purge the outgoing packet queue in the rekey protocol's final
2742 callback to assure that all rekey packets go to the network
2743 before quitting the protocol. Affected file silcd/server.c.
2745 * Added silc_client_packet_queue_parse as similar function as
2746 in server to the client library. The affected file is
2747 lib/silcclient/client.c.
2749 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2751 * Splitted silcd/server.c and created silcd/server_util.[ch]
2752 for utility functions.
2754 * Added new socket flag SILC_SF_DISABLED to indicate that the
2755 connection is open but nothing can be sent to or received from
2756 the connection. Affected file lib/silcutil/silsockconn.[ch].
2757 The checking for disabled socket is checked in the low level
2758 silc_socket_write and silc_socket_read functions.
2760 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * Allow only nicknames and channel names that fits into the
2763 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2765 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * When processing JOIN command reply in server check that if
2768 the channel exists in our global list we'll move it the local
2769 list. Affected file silcd/command_reply.c.
2771 * Fixed the check whether client is joined on the channel already
2772 in JOIN command. Affected file lib/silcclient/command.c.
2774 * Fixed the JOIN command reply to check whether the channel
2775 already exists. Affected file lib/silcclient/command_reply.c.
2777 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Added silc_ske_status_string to map the SKE error numbers
2780 to readable strings. The affected files are
2781 lib/silcske/silcske[_status].[ch].
2783 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2785 * Do not show the private channels on the WHOIS channel list
2786 as it is not allowed by the protocol. The affected file is
2789 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Assure that the packet length digged from the actual packet
2792 is something sensible in the silc_packet_decrypt_rest_special
2793 in lib/silccrypt/silcpacket.c.
2795 * Free and NULL the allocated pointer in silc_hmac_alloc if
2796 the HMAC allocation fails. The affected file is
2797 lib/silccrypt/silchmac.c.
2799 * Print the selected security properties to the log files in
2800 the server. Affected file silcd/protocol.c.
2802 * Add SKE's reference counter even if calling the completion
2803 callback manually. Otherwise it goes negative, although it
2804 does not cause any problems. The affected file is
2805 lib/silcske/silcske.c.
2807 * Remove the client entry with short timeout after giving the
2808 KILL command. Affected file lib/silcclient/command.c.
2810 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2811 case all found clients are already disconnected (WHOWAS would
2812 found them) in the server. Affected file silcd/command.c.
2814 * Update the last_receive (time of last data received) to be
2815 updated only when received private or channel message so that
2816 the idle time showed in WHOIS makes more sense.
2818 * Added boolean field `valid' in to the SilcClientEntry in the
2819 client library to indicate whether the entry is valid or not.
2820 This fixes the nickname change bug on channel when changing
2821 the nickname to be same than the old (like nick to Nick) the
2822 nickname formatter doesn't set the new nick anymore to Nick@host.
2823 Affected file lib/silcclient/idlist.[ch].
2825 * Now actually fixed the nickname changing on disconnection.
2826 Added new function silc_change_nick to the Irssi SILC Client.
2827 Affected file irssi/src/silc/core/client_ops.c,
2828 irssi/src/silc/core/silc-nicklist.[ch].
2830 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Check that the public key exists in the GETKEY command before
2833 trying to encode it. Affected file silcd/command.c.
2835 * Print some notifications on received public keys with GETKEY
2836 command in the Irssi SILC Client. Affected files are
2837 irssi/src/fe-common/silc/module-formats.[ch],
2838 irssi/src/silc/core/client_ops.c.
2840 * Use IDENTIFY command to resolve the server information in the
2841 GETKEY command instead of INFO command. Affected file
2842 lib/silcclient/command.c.
2844 * All command reply functions in the client library now calls
2845 the pending command reply callbacks even if an error has
2846 occurred. The server has done this a long time and now it was
2847 time to move the client library to this as well. Now all
2848 errors can be delivered back to the pending command reply
2849 callbacks if necessary. Affected files are
2850 lib/silcclient/command[_reply].[ch].
2852 * Change the nickname on disconnection back to the username
2853 because in reconnect the server will enforce it to it anyway.
2854 Affected file irssi/src/silc/core/silc-servers.c.
2856 * Fixed a config file parsing bug in the Irssi SILC client.
2857 Affected file irssi/src/silc/core/clientconfig.c.
2859 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * When printing the channel mode on JOIN, verify that the
2862 channel key and channel's HMAC are valid. Affected file
2863 irssi/src/silc/core/client_ops.c.
2865 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2868 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2869 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2871 * Removed channel key rekey task deleting from the function
2872 silc_server_save_channel_key. Affected file silcd/server.c.
2873 Added explicit timeout task context instead that is used to
2874 delete the task if we are registering a new task before the
2875 new task has elapsed.
2877 * When channel key rekey occurs the client library now saves
2878 the old channel key for a short period of time (10 seconds) and
2879 is able to use it in case some is still sending channel
2880 messages encrypted with the old key after the rekey. Affected
2881 file lib/silcclient/[idlist.h|client_channel.c].
2883 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Added check to the silc_server_new_id_real to not accept
2886 new ID if it is the sender's own ID. Affected file is
2887 silcd/packet_receive.c.
2889 * Assure that we do not announce ourself or the one we've
2890 sending our announcements when we're router and are announcing
2891 servers to our primary router. Affected file silcd/server.c.
2893 * Fixed silc_server_command_identify_check_client to assemble
2894 correct WHOIS packet. It send corrupted WHOIS packet and
2895 caused problem with router to router connections. Affected
2896 file silcd/command.c.
2898 Fixed also silc_server_command_whois_check the same way
2899 as for the IDENTIFY command.
2901 * Added new SilcIDListStatus to the server in the SilcIDListData
2902 structure. The status now includes the current status of
2903 the entry (like registered, resolved etc.). Affected file
2904 silcd/idlist.[ch]. Defined a bunch of different status types
2905 as well. This replaced the old boolean registered field as well.
2907 Added resolve_cmd_ident field to the SilcClientEntry structure
2908 too so that if the entry is for example being resolved so
2909 another command may attach to the same pending command reply
2910 without requiring to resolve the same entry again. This concept
2911 should optimize the WHOIS and the IDENTIFY resolving under
2912 heavy load by taking away unnecessary resolving for entries
2913 that are being resolved already.
2915 Added support for adding multiple pending commands for one
2916 command idenfier. Affected file silcd/command[_reply].[ch].
2918 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2919 before deleting the data. Otherwise the hash table will have
2920 freed data in comparison functions. Affected file is
2921 silcd/command_reply.c.
2923 * Fixed silc_idlist_replace_client_id to add the new entry to
2924 the cache with NULL nickname. Otherwise there will be invalid
2925 memory as the nickname after the nickname is freed. Affected
2926 file silcd/packet_receive.c.
2928 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2929 saved into wrong slots because the previous number of entries
2930 was not taken into account. Affected file silcd/idlist.c.
2931 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2933 * If we are router and we receive JOIN notify to a channel that
2934 does not have any users then notified client is marked as the
2935 channel founder, as it is it. The affected file is
2936 silcd/packet_receive.c
2938 * Added to the extended hash table API's table_del_*ext functions
2939 the destructor as argument too, so that the caller can decide
2940 which destructor to use or whether to use destructor at all.
2941 Affected file lib/silcutil/silchashtable.[ch].
2943 * Fixed ID Cache purging. It actually deleted the entries from
2944 the hash table after the data was freed. The hash table ended
2945 up comparing freed memory. The affected file is
2946 lib/silccore/silcidcache.c.
2948 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Fixed Irssi SILC client's KILL command's HELP syntax.
2952 * The USERS command now resolves the detailed user information
2953 if the userinfo field is missing. Affected file is
2954 lib/silcclient/command_reply.c.
2956 * Do not print error in silc_file_read if the read file does
2957 not exist. Just silently return NULL. Affected file is
2958 lib/silcutil/silcutil.c.
2960 * Fixed the silc_log_output to not wine about NULL filename
2961 and to not create some bogus " " filename. Affected file is
2962 lib/silcutil/silclog.c.
2964 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Fixed various printing bugs on the user interface in the
2967 Irssi SILC Client. Minor changes that were forgotten from
2970 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Fixed the configure.in.pre and the compilation and distribution
2973 environment to support the new autoconf 2.52. That version is
2974 now required to compile the CVS trunk.
2976 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2979 to generally parse user@fqdn format strings. Affected file
2980 lib/silcutil/silcutil.c.
2982 * Added nickname_format and nickname_force_format fields to the
2983 SilcClientParams structure. The first one defines the format
2984 for the nicknames that the library will enforce if the receives
2985 multiple same nicknames. The second one is boolean value and
2986 can be used to force the library to always enforce the format
2987 to the nicknames regardles whether there are multiple nicknames
2988 or not. This configurable formatting was employed to flexibly
2989 support accessing multiple nicknames from the user interface.
2990 The userinterface can now set the nicknames to what ever format
2991 they prefer. Affected file lib/silcclient/silcapi.h.
2993 Added function silc_client_nickname_format to the file
2994 lib/silcclient/idlist.c. It performs the nickname formatting.
2996 Added new field `hostname´ to the SilcClientEntry context.
2997 It holds the hostname of the client. Affected file is
2998 lib/silcclient/idlist.h.
3000 * Irssi SILC Client sets the nicknames in nick@hostn format.
3001 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3002 irssi/src/silc/core/silc-core.c.
3004 The WHOIS printing now also shows both the real nickname and
3005 the formatted nickname so that user knows how to access the
3006 user if there are multiple same nicknames cached. Affected
3007 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3008 printing formatting too to take the hostname now as a separate
3009 argument. The Affected file is
3010 irssi/src/fe-common/silc/modules-formats.[ch].
3012 * Changed the silc_client_get_clients_local to accept the formatted
3013 nickname as argument. It accepts the real nickname too but the
3014 formatted nickname can be used to find the true entry from
3015 multiple entries. Affected file lib/silcclient/silcapi.h and
3016 lib/silcclient/idlist.c.
3018 * Added nickname_format_parse field to the SilcClientParams.
3019 It is a callback function provided by the application to parse
3020 the nickname out of the formatted nickname string. The library
3021 calls it to get the nickname from the formatted string. Since
3022 the application generally knows better the format of the nickname
3023 string it parses it instead of the library, even though library
3024 encodes the formatted string. If the callback function is not
3025 provided then the library will use the string as is. The
3026 affected file is lib/silcclient/silcapi.h.
3028 * All the nickname strings passed to the client library in
3029 commands are now expected to be formatted nickname strings.
3030 If the command does not support the formatted nickname string
3031 it will assume that the sent string is the actual nickname.
3032 Affected file lib/silcclient/command.c.
3034 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Added public key authentication support to OPER and SILCOPER
3037 commands in the client library. Affected file is
3038 lib/silcclient/command.c.
3040 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Changed the get_auth_methdod client operation to be asynchronous.
3043 It can be async if the application resolves the authentication
3044 method from the server during the negotiation. Added new
3045 SilcGetAuthMeth completion callback that the application will
3046 call after resolving the authentication method.
3048 Added function silc_client_request_authentication_method that
3049 the application can use to resolve the authentication method
3050 from the server. Added also SilcConnectionAuthRequest callback
3051 that the library will call after the server has replied. The
3052 application can call this function if it does not know the
3053 current authentication method.
3055 Affected files are lib/silcclient/client.c and
3056 lib/silcclient/silcapi.h.
3058 * The Irssi SILC client now automatically resolves the authentication
3059 method incase any configuration information is not present (and
3060 currently there never is). The affected file is
3061 irssi/src/silc/core/client_ops.c.
3063 * Fixed public key authentication from the client library.
3064 Affected file lib/silcclient/protocol.c. Changed also the
3065 protocol specification about the public key authentication in
3066 the connection authentication protocol. The actual data to be
3067 signed is now computed with a hash function before signing.
3069 * Fixed the public key authentication from the server as well.
3070 Affected file silcd/protocol.c.
3072 * Removed the mlock()'s from the memory allocation routines.
3073 Affected file lib/silcutil/silcmemory.c. The ./configure does
3074 not check anymore for the mlock(). Affected file is
3077 * Fixed USERS command in server to allow the execution of the
3078 command for private and secret channels if the client sending
3079 the command is on the channel. Affected file silcd/command.c.
3081 * Fixed silc_client_get_clients_local to return the clients
3082 count correctly. It could return wrong value. Affected file
3083 lib/silcclient/idlist.c.
3085 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3088 types. The assembler optimizations seemed not to like 64-bit
3089 data types. The assmebler optimizations thus are now enabled
3090 also for BSD systems as opposed to only enable them for Linux.
3092 * Do not check for threads at all on BSD systems. Affected
3093 file configure.in.pre.
3095 * Removed -n and -h options from the Irssi SILC Client since
3096 they are not used in silc.
3098 * Fixed the prime generation to assure that the first digit
3099 of the generated random number is not zero since our conversion
3100 routines does not like number strings that starts with zero
3101 digit. If zero digit is seen the random number is regenerated.
3102 This caused some corrupted RSA keys when the zero first digit
3103 was met. Affected file lib/silcmath/silcprimegen.c.
3105 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Fixed WIN32 configuration in the ./configure script.
3108 Fixed to include xti.h on environments that has it.
3109 Patches by Carsten Ilchmann and andrew.
3111 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Changed the silc_id_create_client_id to be collision
3114 resistant. It is now assured that there cannot be created
3115 two same client ID's. I suspect that some weird bugs in
3116 the server were actually caused by duplicate Client IDs.
3117 Affected file silcd/serverid.[ch]. A router receiving
3118 new ID now also assures and informs the sending server
3119 if the ID caused collision.
3121 * Changed the silc_id_create_channel_id to also assure that
3122 there are no collisions.
3124 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * Statement about ignoring the Mutual Authentication flag when
3127 performing rekey with PFS was a bit misleading. It is ignored
3128 if it was set in the initial negotiation, it cannot be even
3129 set in the rekey. Fixed in the ke-auth draft. Started the
3130 new versions of the protocol drafts in the doc/.
3132 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Fixed a bug in silc_client_command_identify_save when saving
3135 new channel information. The channel name was no duplicated
3136 and caused crash on exit. Affected file is
3137 lib/silcclient/command_reply.c.
3139 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3141 * Fixed the getkey command handling in the server. Send just
3142 empty OK reply to the sender if the key could not be fetched
3143 (but everything else was ok, like the key just was not available).
3144 Changed the public key parameter to optional in the protocol
3145 specs so that empty OK reply can be sent. Affected file
3148 Added a message to Irssi SILC client to tell to user if the
3149 server did not return a public key.
3151 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Fixed a channel key regeneration bug. It registered new
3154 timeout tasks exponentially until all system resources were
3155 used. Affected file silcd/server.c.
3157 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Added the SILC Document generator to the scripts/silcdoc.
3160 It can be used to generate the Toolkit Reference Manual out
3161 of the source tree. Internally it will also use the RoboDoc
3162 generator now imported in util/robodoc.
3164 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Added couple of return's in rekey protocol if error orccurred
3167 during the protocol. The execution must be terminated.
3168 Affected file silcd/protocol.c. Also, terminate the protocol
3169 always with timeout.
3171 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * The client's Client ID was created initally from the wrong
3174 nickname (it could have been in format nick@host) in the
3175 silc_server_new_client. Affected file silcd/packet_receive.c
3177 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Added some SILC_LOG_ERROR's to various error conditions
3180 if client could not be added to ID cache. Affected files
3181 silcd/packet_receive.c and silcd/server.c.
3183 * When client's sock->user_data is freed, NULL also the
3184 client->router and client->connection pointers. Added check
3185 for these pointers being NULL to various places around the
3186 code. Affected file silcd/server.c.
3188 * Added client->data.registered == TRUE checks to various
3189 places around the code to assure that unregistered client's
3190 are not handled when it is not allowed. Affected file
3193 * Added `bool registered' fields to all
3194 silc_idlist_[server|client]_get_* routines to indicate whether
3195 the fetched client needs to be registered or not. Affected
3196 file silcd/idlist.[ch].
3198 * Add your own entry as registered to the ID cache in the
3199 server. Affected file server.c.
3201 * Fixed a bug in silc_server_new_server. The SilcServer was
3202 set as the new server's context instead of SilcServerEntry.
3203 This naturally caused some weird bugs.
3205 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Do not delete the channel rekey task when adding it
3208 for in silc_server_create_channel_key.
3210 * Changed the silc_server_create_channel_key to return
3211 TRUE or FALSE to indicate the success of the channel key
3214 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3216 * Fixed MSVC++ project files and added missing files to

3222 does not have it defined. Affected files are
3223 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3225 * Fixed buffer overflow from Irssi SILC Client. Affected
3226 file irssi/src/fe-common/core/themes.c.
3228 * Fixed double free in client library in the file
3229 lib/silcclient/client.c when disconnecting from server.
3231 * Applied double free patch from cras to Irssi SILC client.
3232 Affected files irssi/src/core/[modules/expandos].c
3234 * Fixed the disconnection handling to Irssi SILC Client.
3235 The application must call silc_client_close_connection
3236 in ops->connect client operation in case of failure of
3237 the connection. Affected file is
3238 irssi/src/silc/core/client_ops.c.
3240 * Do not set sock->protocol to NULL in the function
3241 silc_client_close_connection after executing the protocol's
3242 final callback since the sock might not be valid anymore.
3243 Affected file lib/silcclient/client.c.
3245 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3247 * Do not enable SILC_THREADS if the linking with libpthread
3248 did not happen. Affected file configure.in.pre.
3250 * Added notion to protocol specification that server must
3251 verify the sent authentication payload with CMODE when
3252 setting the channel founder key. Implemented it to the
3253 server. Affected file silcd/command.c.
3255 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Added _EXTRA_DIST SILC distribution variable to the
3258 distributions file. It is used to conditionally add extra
3259 files or directories to the specific distribution. Affected
3260 files ./prepare, Makefile.am.pre and distributions.
3262 Removed the `_' from the start of the distribution names.
3265 * Added README.WIN32 for instructions to compile the Toolkit
3268 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Fixed a double free in disconnection in the server. Affected
3271 file is silcd/server.c.
3273 * Fixed the lib/silcske/groups.c to work now also with GMP
3274 MP library. The string conversion did not work when using
3275 specific base and the base is indicated in the string as well.
3277 * Created win32/ directory which now includes MSVC++ specific
3278 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3279 It will appear only in the toolkit distribution
3281 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Changed the key material distribution function in case when
3284 the hash output is too short. The data is now concatenated
3285 a bit differently than it used to. Made the change to the
3286 SKE protocol specification.
3288 * Added better GMP detection to configure.in.pre. A patch
3291 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Fixed a minor bug in SKE that might cause some problem on
3294 some platforms. Affected file lib/silcske/silcske.c.
3296 * Added the cookie checking for initiator in the SKE. It checks
3297 that the responder returns the sent cookie unmodified. The
3298 affected file is lib/silcske/silcske.c. Added new SKE
3299 error type INVALID_COOKIE that can be sent during the
3300 negotiation. Fixed some memory leaks as well.
3302 * Added the "invalid cookie" error message to Irssi SILC client's
3305 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Added `task_max' field to the SilcClientParams to indicate
3308 the maximum tasks the scheduler can handle. If set to zero,
3309 default values are used. Affected file lib/silcclient/silcapi.h.
3311 * Fixed memory leaks in silc_client_close_connection. Affected
3312 file lib/silcclient/client.c.
3314 * Added silc_client_del_client_entry to client library to free
3315 all memory of given client entry. Affected file is
3316 lib/silcclient/idlist.[ch].
3318 * Added new functions silc_client_del_channel and
3319 silc_client_del_server to delete channel and server entries.
3320 Affected file lib/silcclient/[silcapi.h/idlist.c].
3322 * Removed silc_client_del_client_by_id from silcapi.h.
3324 * Fixed the INFO command to return the server's own info
3325 correctly when querying by Server ID. Affected file is
3328 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Removed the non-blocking settings in WIN32 code in the
3331 silc_sock_[read/write] and added SleepEx instead. Affected
3332 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3333 of input data is now checked with FIONREAD and ioctlsocket.
3335 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * Call silc_schedule_task_del_by_context in the
3338 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3339 Affected file lib/silccore/silcprotocol.c.
3341 * Call silc_protocol_cancel for active protocols in the
3342 silc_server_close_connection if the funtion
3343 silc_server_free_sock_user_data has not been called.
3344 Affected file silcd/server.c.
3346 * Generic tasks cannot be deleted using the del_by_fd
3347 task deleting function since generic tasks does not match
3348 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3350 * Added a notion to SILCOPER help file that the SILCOPER works
3351 only on router server, not on normal server.
3353 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Added for WIN32 support for the new scheduler as well.
3356 Affected file lib/silcutil/win32/silcwin32schedule.c.
3358 * Fixed the SHA1 implementation to work on various platforms.
3360 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3362 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3363 API. It is part of the scheduler now. Everything else is
3364 as previously but some functions has changed their names.
3365 Checkout the lib/silcutil/silcschedule.h for the interface.
3366 Updated all applications to use the new interface. Affected
3367 files are lib/silcutil/silcschedule.[ch].
3369 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * Found a bug in the SKE implementation. The HASH value,
3372 specified by the protocol, was not computed correctly. The
3373 public key of the responder was not added to the computation
3374 even though it is mandatory. Affected file lib/silcske/silcske.c.
3375 This unfortunately causes incompatibilities with older
3376 clients and servers.
3378 * Added WIN32 specific network init and uninit functions:
3379 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3380 the Winsock2. Affected file lib/silcutil/silcnet.h and
3381 lib/silcutil/win32/silcwin32net.c.
3383 * Set the socket always to nonblocking mode on WIN32 after
3384 reading data or writing data. Affected file is
3385 lib/silcutil/win32/silcwin32sockconn.c.
3387 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Fixed various compilation problems under WIN32. Affected
3390 files lib/silcutil/win32/silcwin32thread.c and
3391 lib/silcutil/win32/silcwin32schedule.c.
3393 * Removed all _internal.h #includes from public header
3394 files. Internal headers must never be included from
3397 Removed also the lib/silcske/payload_internal.h file.
3399 * All include files that may be needed (public and some others
3400 included by the public headers) by application developers are
3401 now copied to the ./includes directory. It does not copy any
3402 internal headers. Affected file Makefile.defines.pre and all
3403 Makefile.am's under lib/ and subdirs.
3405 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Do not change the ~/.silc directory's permissions automatically.
3408 Affected file irssi/src/silc/core/clientutil.c.
3410 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Do not cancel the protocol in silc_server_close_connection
3413 it might cause recursion. Now cancelled in the function
3414 silc_server_free_sock_user_data. Affected file silcd/server.c.
3416 * Fixed the silc_server_remove_clients_by_server to regenerate
3417 the channel keys correctly finally. Added also new function
3418 silc_server_remove_clients_channels to actually do it.
3419 Affected file silcd/server.c.
3421 * Fixed the silc_server_new_channel to not crash by giving
3422 wrong router to the new channel. Affected file is
3423 silcd/packet_receive.c.
3425 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3428 which is given as argument to the silc_client_alloc now.
3429 It can be used to configure the client and set various parameters
3430 that affect the function of the client.
3432 * The USERS command in server did not check whether the channel
3433 is private or secret. Affected file silcd/command.c.
3435 * Added new argument to the USERS command in protocol specification.
3436 The USERS command now can take the channel name as argument
3437 as well. Added support for this in client and server and
3438 updated the protocol specs.
3440 * Completed the GETKEY command in client. It can be now used
3441 to fetch also servers public key not only some clients.
3442 Affected files lib/silcclient/command[_reply].c.
3444 * Added silc_client_get_server to return server entry by the
3445 server name. Affected files lib/silcclient/silcapi.h and
3448 * Redefined the IDENTIFY command in protocol specification to be
3449 more generic. It now can be used to query information about
3450 any entity in the SILC Network, including clients, servers and
3451 channels. The query may be based either the entity's name
3452 or the ID. Added support for this in both client and server.
3454 Affected files silcd/command.c and lib/silcclient/command.c
3455 and command_reply.c.
3457 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3458 the _from_client and _from_server functions. Affected file
3461 * Added silc_client_get_channel_by_id_resolve to the file
3462 lib/silcclient/silcapi.h to resolve channel information by
3463 its ID. Added also silc_client_get_channel_by_id that
3464 does not resolve it from the server.
3466 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Added SilcServerEntry context into the client library
3469 to represent one server. The INFO command now allocates
3470 these to save the resolved server info. For now on the
3471 client library will also keep information about servers,
3472 connected and resolved with INFO.
3474 The INFO command now allocates the SilcServerEntry context
3475 and saves the server info there. The COMMAND_REPLY in
3476 the INFO now returns the parameters to application in
3477 same order as defined in the protocol specification.
3479 The entries are cached in the client->server_cache.
3481 * The INFO command is now issued after received the Client ID
3482 from the server. Affected file lib/silcclient/client.c.
3484 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3485 to the application as the mode changer might be server.
3486 It is guaranteed that NULL is not returned anymore to the
3487 application. Affected file lib/silcclient/client_notify.c.
3489 The ID Type is now also passed to the application so that
3490 it can check whether the returned entry is SilcClientEntry
3493 Added new function silc_client_get_server_by_id to return
3494 the server entry by ID. Affected files are the
3495 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3497 * Do not create the channel in the Irssi SILC Client when issuing
3498 the JOIN command but when received the sucessful JOIN command
3499 reply. Otherwise the channel might get created even though we
3500 could not join it. The Affected file is
3501 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3503 * Fixed a channel joining bug in router. The router must also
3504 check the channel modes, invite and ban lists etc. when serving
3505 the JOIN command sent by normal server. Affected file is
3506 silcd/command.c. The router now resolves the client's
3507 information from the server who sent the JOIN command if it
3508 does not know it, and processes the JOIN command only after
3511 * Changed the SilcCommandCb to take new argument; void *context2.
3512 Affected file lib/silccore/silccommand.h
3514 The second argument in the command callbacks in the server now
3515 includes the SilcServerCommandReplyContext if the command was
3516 called as pending command callback from the command reply.
3517 Otherwise it is NULL. When called as pending the status of the
3518 command reply will be checked and if it was erronous the
3519 error will be sent to the original sender of the command.
3520 This way the client always receives the error messages even
3521 though the server was actually the one who received the error
3522 when it resent the command to router, for example. Affected
3523 files silcd/command[_reply].[ch].
3525 * Fixed sending WHOWAS command's error message to client if
3526 the requested client could not be found. It was missing.
3529 * Changed the CMODE and CUMODE commands reply arguments in the
3530 protocol specification. The Channel ID is now sent in both
3531 of the commands to identify the channel. Implemented this
3532 new feature to the client and server. Affected files
3533 lib/silcclient/command_reply.c and silcd/command.c.
3535 * Made better checks for invite and ban lists in the JOIN
3536 command in server. Affected file silcd/command.c.
3538 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * The server now performs the incoming host IP/DNS lookup
3541 using the silc_socket_host_lookup and thus does not block
3542 the server anymore. Affected file silcd/server.c.
3544 * Completed the multi-thread support for SILC Scheduler in
3545 the lib/silcutil/silcschedule.c.
3547 * Fixed the configure.in.pre to detect the pthread correctly
3550 * Fixed a deadlock in silc_task_queue_wakeup in the file
3551 lib/silcutil/silctask.c.
3553 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Added new function silc_schedule_wakeup that is used in
3556 multi-threaded environment to wakeup the main thread's
3557 schduler. It needs to be used when a thread adds a new task
3558 or removes a task from task queues. After waking up, the
3559 scheduler will detect the task queue changes. If threads
3560 support is not compiled in this function has no effect.
3561 Implemented the wakeup mechanism to both Unix and WIN32
3562 systems. Affected files are lib/silcutil/silcschedule.[ch],
3563 lib/silcutil/unix/silcunixschedule.c and the
3564 lib/silcutil/win32/silcwin32schedule.c.
3566 * Added new function silc_task_queue_wakeup to wakeup the
3567 scheduler by the specified task queue. Affected file
3568 lib/silcutil/silctask.[ch].
3570 * The silc_socket_host_lookup_start now wakes up the scheduler
3571 after adding the timeout task. Affected file is
3572 lib/silcutil/silcsockconn.c.
3574 * The silc_socket_host_lookup is synchronous now if the threads
3575 support is not compiled in. However, the callback is still
3576 called asyncronously through the scheduler, anyway. Affected
3577 file lib/silcutil/silcsockconn.c.
3579 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3581 * Added new function silc_socket_host_lookup to perform
3582 asynchronous IP and FQDN lookups for the socket connection.
3583 Affected files lib/silcutil/silcsockconn.[ch].
3585 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3588 that may or may not compile the mutex support in.
3590 Changed the silc_mutex_alloc interface. It allocates the
3591 mutex now to the sent pointer and returns TRUE or FALSE.
3593 Affected file lib/silcutil/silcmutex.h.
3595 * Wrote the SILC Task Queue interface to support multi-threads.
3596 Affected file lib/silcutil/silctask.[ch].
3598 * Wrote the SILC Scheduler to support multi-threads. Affected
3599 file lib/silcutil/silcschedule.c.
3601 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3604 in lib/silcutil/win32/.
3606 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Defined SILC Mutex API and SILC Thread API and implemented
3609 them for Unix. Affected files are
3610 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3611 lib/silcutil/unix/silcunixmutex.c and
3612 lib/silcutil/unix/silcunixthread.c.
3614 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Fixed the silc_server_remove_clients_by_server's channel
3617 key re-generation. The hash table handling was incorrect
3618 and would not work with many channels. Affected file is
3621 * Fixed some memory leaks around the server code.
3623 * Rewrote the silc_server_get_users_on_channel to support IPv6
3624 based Client ID's. Affected file silcd/server.c.
3626 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3627 specification. However, a separate document must be written
3628 to define the detailed signing procedure and the payload
3629 associated with the flag. Defined the flag to the
3630 lib/silccore/silcchannel.h as well.
3632 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3634 * Changed the dynamic tables to static size tables in the
3635 lib/silccrypt/silchmac.c.
3637 * Removed GCC dependencies from the code. A patch by cras.
3639 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Do not show the error "Error receiving packet bla bla"
3642 in server if it really was not an error (-2 means that reading
3643 is pending). Affected file silcd/server.c.
3645 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3647 * Fixed a possible crash in silc_server_remove_clients_by_server
3648 in silcd/server.c. Fixed there also some memory leaks.
3650 * Fixed the silc_idlist_replace_client_id. It could replace
3651 wrong key in the hash table. Affected file silcd/idlist.c.
3653 * Do not check whether there are global users on the channel
3654 if the channel->global_users is FALSE. Affected functions
3655 silc_server_remove_from_one_channel and
3656 silc_server_remove_from_channels in silcd/server.c. Also,
3657 do not check if the removed client is local as we can be
3658 sure that global client was not removed from the channel
3659 and checking for global users is not needed.
3661 * The silc_server_remove_clients_by_server now re-generates
3662 the channel keys correctly for those channels that had
3663 clients removed from them. Affected file silcd/server.c.
3665 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Found the reason of random crashes in the server. We weren't
3668 ignoring the SIGPIPE signal (which can be sent in write())
3669 and it crashed the server. Affected file silcd/silcd.c.
3671 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3673 * Assure that sock->user_data is not NULL in the function
3674 silc_server_packet_send in silcd/packet_send.c.
3676 * Disconnect the remote connection if it could not be added
3677 to any ID lists in the server. The affected file is
3680 * Check in silc_server_packet_send[_real/dest] that the
3681 socket is not disconnecting and ignore the data if it is.
3682 Affected file silcd/packet_send.c.
3684 * Define inline to __inline on native WIN32 compilation.
3685 Affected file includes/silcwin32.h.
3687 * Added some explicit type casts for inline code since MSVC
3688 require them. Affected files lib/silcutil/silcbuffer.h,
3689 lib/trq/silcdlist.h and lib/trq/silclist.h.
3691 * Print warning in log files from now on if the packet
3692 decryption fails. Affected file silcd/server.c.
3694 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3696 * Changed the `say' client operation's interface to accept
3697 new `type' argument to indicate the type of the message sent
3698 by the library. The application may filter the library's
3699 messages according the type. The affected file is the
3700 lib/silcclient/silcapi.h.
3702 * Added two new functions to lib/silcclient/silcapi.h:
3703 silc_client_del_client and silc_client_del_client_by_id.
3704 Affected file lib/silcclient/idlist.c.
3706 * Moved the clientincludes.h from includes/ to silc/ and
3707 serverincludes.h from includes/ to silcd/.
3709 * The modes for the CMODE and CUMODE are now passed as
3710 uint32 for application with COMMAND_REPLY. The affected
3711 file is lib/silcclient/command_reply.c.
3713 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3715 * /WHOIS without arguments shows client's own information.
3716 Affected file lib/silcclient/command.c.
3718 * Changed PING to not accept any arguments. The specs
3719 says that client can ping only the connected server so
3720 requiring an argument is not needed. Affected file is
3721 lib/silcclient/command.c.
3723 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3725 * Fixed a fatal bug in private message sending and reception
3726 encryption and decryption when using private message keys.
3727 The implementation was incorrect and did not follow the
3728 specification. It causd that some of the message were
3729 lost since it did not use the sending and receiving keys
3730 as the protocol suggests. This has been fixed and will cause
3731 incompatibilities with older clients when sending private
3732 message encrypted with private message keys. Affected files
3733 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3734 and various other in Irssi SILC Client.
3736 Added `responder' boolean argument to the functions
3737 silc_client_add_private_message_key[_ske] to indicate when
3738 the key is added as responder or initiator of the key
3741 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Removed the silc_ske_check_version function and created
3744 a SilcSKECheckVersion callback. Added also a function
3745 silc_ske_set_callbacks that is now used to set all SKE
3746 callbacks. The callback functions are not given to
3747 the SKE functions anymore, but this function is used to
3750 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3752 * Added `silc_version' argument to the silc_client_alloc
3753 to define the version of the application for the library.
3754 The library will use the version string to compare it
3755 against the remote host's (usually a server) version
3756 string. Affected file lib/silcclient/silcapi.h
3758 * Added the KE protocol context to Key Agreement context
3759 in client library so that we can abort the SKE if it
3760 is in process when we get timeout. Affected file is
3761 lib/silcclient/client_keyagr.c.
3763 * Do not resolve the client ID forever if it returns in the
3764 first time that such client does not exist. This was done
3765 for example with private message. Affected file is
3766 lib/silcclient/client_prvmsg.c.
3768 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3770 * Do not add regex.h for WIN32. The affected file
3771 includes/silcincludes.h.
3773 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3774 not work yet 100%. It generates the DLL's automatically
3775 when compiling with --with-win32 under cygwin.
3777 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3779 * lib/contrib/regex.c is not compiled on WIN32.
3781 * Added silc_net_get_socket_opt function to the
3782 lib/silcutil/silcnet.h.
3784 * Added includes/silcwin32.h for WIN32 specific includes
3787 * Do not use ptime structure or any of the posix process
3788 functions on WIN32 in lib/silccrypt/silrng.c.
3790 * Added silc_gettimeofday to provide generic function
3791 for struct timeval on all platforms. Added the function
3792 to lib/silcutil/silcutil.h.
3794 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3796 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3797 library as they clearly belong there. As a plus side we
3798 can make the actual socket connection routines platform
3801 Added also new generic function silc_socket_read and
3802 silc_socket_write (that used to be silc_packet_[read/write].
3803 The implementation of these are platform specific.
3805 * Added WIN32 specific routines of silc_socket_[read/write]
3806 to lib/silcutil/win32/silcwin32sockconn.c.
3808 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Added preliminary support for native WIN32 compilation under
3811 cygwin (using the -mno-cygwin option for GCC) to the
3812 ./configure.in.pre. The --with-win32 now prepares the
3813 compilation for native WIN32.
3815 * Rewrote the SILC Scheduler interface in the file
3816 lib/silcutil/silcschedule.h. The scheduler is now context
3817 based and does not have anymore any global static scheduler.
3818 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3819 and created lib/silcutil/win32 directory for WIN32 based
3822 * Added Unix specific network routines to the
3823 lib/silcutil/unix/silcunixnet.c and the old
3824 lib/silcutil/silcnet.c includes now only generic routines.
3826 Added WIN32 specific network routines to the
3827 lib/silcutil/win32/silcwin32net.c.
3829 * Added Unix specific utility functions from the
3830 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3832 * Added WIN32 SILC Scheduler to the file
3833 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3836 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Do not handle JOIN notify in the server if the target client
3839 is not registered (idata->registered == FALSE). The affected
3840 file is silcd/packet_receive.c.
3842 * Update the nickrec->founder in event_cumode in the Irssi SILC
3843 client. Affected file irssi/src/silc/core/silc-channels.c.
3845 * Fixed the CUMODE_CHANGE notify handling in the server when
3846 server and router are announcing their clients on channels.
3847 Now the mode changes are saved and notified correctly. The
3848 affected file is /silcd/packet_receive.c.
3850 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3851 They really did not replace the cache entry in the ID Cache.
3852 Now they do that. Affected file silcd/idlist.c.
3854 * Fixed the KICK notify handling in the Irssi SILC client to
3855 update the channel records so that the kicked client does not
3856 appear to be on the channel. The affected file is
3857 irssi/src/silc/core/silc-channels.c.
3859 * Always update the conn->current_channel when executing command
3860 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3862 * Fixed the KILL notify handling in Irssi SILC client to remove
3863 the killed client on all channels.
3865 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Fixed the silc_parse_command_line to remove extra spaces
3868 from the start and end of the arguments. Affected file is
3869 lib/silcutil/silcutil.c.
3871 * Cancel and free any active protocol in the function
3872 silc_server_close_connection. Affected file silcd/server.c.
3874 * Cancel and free any active protocol in the function
3875 silc_client_close_connction. Affected file is
3876 lib/silcclient/client.c.
3878 * Do not execute the KILL command for clients that are in
3879 history (ie. they are not in the network). Affected file is
3882 * Fixed KILL notify handling, client does not crash anymore.
3883 Affected file irssi/src/silc/core/silc-channels.c.
3885 * Reduced the default packet buffer size from 2048 to 1024 in
3886 lib/silccore/silcpacket.c.
3888 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3889 counter to the SKE context that is incresed when the SKE library
3890 performs async operation outside the library. If the outside
3891 process frees the SKE context and FREED status will be set
3892 and the library will detect after the sync operation that the
3893 libary is freed. The affected files are
3894 lib/silcske/silcske[_status].[ch].
3896 * Resolve the client entry information in the function
3897 silc_client_channel_message to assure that NULL pointer is not
3898 passed as client entry to the application. */
3900 * Fixed the task timeout calculation to assure that there is
3901 never negative timeouts. The affected file is
3902 lib/silcutil/silcschedule.c.
3904 * Fixed the channel user mode notification sending in server.
3905 It was sent point-to-point to the router (or to server by router)
3906 but it needs to be destined to a channel. The routines now
3907 supports sending the channel user mode notifys to the channels
3908 when announcing clients and channels. Affected files are
3909 silcd/server.c and silcd/packet_receive.c.
3911 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3912 It did not actually replace the old channel entry in the cache.
3913 Affected file lib/silcclient/client_notify.c.
3915 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Fixed a possible crash in silc_packet_send_prepare. It now
3918 assures always that there is enough space in the buffer and
3919 at the tail area of the buffer (for MAC).
3921 Fixed the inbound buffer reallocation in silc_packet_read.
3922 It was old code and did not handle the reallocation correctly.
3925 The affected file is lib/silccore/silcpacket.c.
3927 * Fixed buffer overflow in silc_parse_nickname in the file
3928 lib/silcutil/silcutil.c.
3930 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * make install generates new server keys only if there is not
3935 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3938 Added check that if the NOREPLY is set then we will not send
3939 the away message. This avoids infinite loop of away messages
3940 if both clients are away. The affected file is
3941 lib/silcclient/client_prvmsg.c.
3943 * Fixed client crash if /NICK was given without arguments.
3944 Affected file lib/silcclient/command.c.
3946 * Server does not send the invite list in INVITE command back
3947 to the client if the list was not altered. Added this notion
3948 to the protocol spec as well. Affected file silcd/command.c.
3950 Fixed possible crash in INVITE command by checking the
3951 value of silc_server_get_client_route command.
3953 * Fixed the INVITE notify type handling. The arguments are now
3954 taken in correct order and client does not crash. The affected
3955 file is irssi/src/silc/core/silc-channels.c.
3957 Removed the "Inviting xxx to channel" message from the
3958 client library away and let the application handle it.
3959 Affected file lib/silcclient/command.c. Added that message
3960 to Irssi SILC client's message formats.
3962 * Fixed CMODE command crash in client. It now checks the
3963 amount of arguments correctly and does not crash. The affected
3964 file is lib/silcclient/command.c.
3966 * Do not create new channel automatically in silc_channels_join
3967 but check whether the channel by that name already exists.
3968 Affected file irssi/silc/core/silc-channels.c.
3970 * Do not send the SERVER_SIGNOFF to router if the disconnected
3971 entity was the router. Affected file silcd/server.c.
3973 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3974 SILC client as it was missing from there.
3976 Added the handling of the KICK notify to the Irssi SILC client
3977 as it was missing. Added "you have been kicked" message to
3978 Irssi SILC client's message modules formats.
3980 Added the handing of the KILL notify to the Irssi SILC client
3981 as it was missing. Added the kill message module formats
3984 The affected file is irssi/src/silc/core/silc-channels.c.
3986 * The router did not save the channel mode the server announced.
3987 Affected file silcd/packet_receive.c.
3989 * Fixed a possible crash in INFO command in server. If the
3990 server did not provide the server info it crashed. Affected
3991 file silcd/command.c.
3993 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Fixed the GETKEY command in the server to check also the
3996 global list. Otherwise the GETKEY would not work correctly
3997 in normal SILC server. Affected file silcd/command.c.
3999 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed GETKEY crash, it crashed if the command did not succseed.
4003 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4006 is now real and not just an macro interface to GMP.
4008 Removed the entire GMP from the source tree and imported new
4009 NSS MPI library instead. Reason for removing GMP is that it is
4010 extremely large and compiles extremely slow. The NSS MPI
4011 is only a few files and compiles in less than 10 seconds.
4012 The speed is also about the same as GMP. The MPI is imported
4013 to lib/silcmath/mpi.
4015 If the system has GMP installed we will still use the GMP.
4016 If it is not then the NSS MPI will be compiled.
4018 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Merged a long nickname (127 characters long) crash bugfix from
4021 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4023 * Merged a freed memory reference bugfix from Irssi CVS tree.
4024 Affected file irssi/src/core/commands.c.
4026 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Added the server's public key sving and verification to the
4029 server when performing the SKE. This was missing and the
4030 remote server's (or router's) public key was accepted without
4031 checking whether we have it previously or trust it at all.
4032 Affected file silcd/protocol.c.
4034 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Check in the silc_server_timeout_remote if protocol is active
4037 and make sure that the protocol's final callback is called so
4038 that all memory if freed. Affected file silcd/server.c.
4040 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * silc_server_whois_send_reply crashed the server if the nickname
4043 was 127 characters long. Affected file silcd/command.c.
4045 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Added sanity check to the silc_server_new_client. If the hostname
4048 is provided inside username then check that the provided hostname
4049 really is the same as the resolved one. If the hostname was not
4050 resolved then check it from the public key. Affected file is
4051 silcd/packet_receive.c.
4053 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4054 if the server disconnected us and the connection is not valid
4055 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4057 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4058 the library to the lib/silcutil/silcutil.[ch].
4060 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Close log file after open. Affected file
4063 lib/silcutil/silclog.c.
4065 * Check whether sock == NULL in silc_client_send_packet and return
4066 if it is. Affected file lib/silcclient/silcclient.c.
4068 * Check rec->entry == NULL in the Irssi SILC Client before
4069 sending the channel message. Affecte file is
4070 irssi/src/silc/core/silc-servers.c.
4072 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Merged a splitted window bugfix from Irssi CVS tree. The
4075 affected file is irssi/src/fe-text/textbuffer-view.c.
4077 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4078 It did not print nickname.
4080 * Improved the distributions system a bit.
4082 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4085 irssi/src/fe-text/gui-window.c.
4087 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4088 to in-active server. The affected file is
4089 irssi/src/silc/core/client_ops.c.
4091 * Resolve the client in USERS command reply if the entry does
4092 not have username resolved. The affected file is
4093 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4094 command to WHOIS command to really resolve stuff. The USERS
4095 is not used any more in any critical section so WHOIS can
4096 be used even though it might be slower than IDENTIFY.
4098 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4101 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Changed the protocol API a bit more consistent in the
4104 lib/silccore/silcprotocol.[ch].
4106 * Changed the following headers to ROBODoc format:
4108 lib/silccore/silcpayload.h
4109 lib/silccore/silcprotocol.h
4110 lib/silccore/silcsockconn.h
4112 All core library headers are now formatted.
4114 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Fixed a bug in Irssi SILC client; do not show that you are
4117 server/router operator if you really are not. Affected file is
4118 irssi/src/silc/core/client_ops.c.
4120 * Renamed silc_command_free_payload to silc_command_payload_free.
4121 Affected file lib/silccore/silccommand.h
4123 * Added silcmath.h to include the prototoypes of various routines
4124 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4127 * Changed the following headers to ROBODoc format:
4129 lib/silccore/silcchannel.h
4130 lib/silccore/silccommand.h
4131 lib/silccore/silcid.h
4132 lib/silccore/silcidcache.h
4133 lib/silccore/silcmode.h
4134 lib/silccore/silcnotify.h
4135 lib/silccore/silcpacket.h
4136 lib/silcmath/silcmath.h
4138 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Added checking to the server code not to start the server if
4141 ciphers and stuff are not configured properly. Affected files
4142 silcd/serverconfig.[h] and silcd/server.c.
4144 * Changed the layout of the header files of the public interfaces
4145 in the SILC libraries. The new layout supports ROBODoc
4146 documentation tool (and some others) so that it is easy to create
4147 a library reference manual. All the other headers and source
4148 code must still follow the CodingStyle document. Also source
4149 code must not include these ROBODoc stuffs, only the headers.
4150 Furthermore, all public interface headers must now be named
4151 by using `silc' prefix, example: silcapi.h, silccipher.h.
4152 Some files were renamed due to this. All the other headers
4153 must not be used as public interfaces. I will update the
4154 CodingStyle document later. Changed following headers, so far:
4156 lib/silcclient/silcapi.h
4157 lib/silccore/silcauth.h
4158 lib/silccore/silcprivate.h
4159 lib/silccrypt/silcdh.h
4161 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Removed silc_client_packet_send_flush from the client library
4166 as it is not needed. Affected file lib/silcclient/client.[ch].
4168 * Added printing of message of unresolved authentication method
4169 to the Irssi SILC client. Added it to the module formats.
4170 Removed the same message from the client library.
4172 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Added new distribution feature, DISTLABEL. Every distribution
4175 can define own preprocessor label that can be used in the
4176 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4177 file distributions, acconfig.h.pre and prepare.
4179 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Added Makefile.defines_int to include the actual definitions
4182 for Makefile.defines.in. Tested the new distribution system,
4183 created distributions and tested installation.
4185 * Added AWAY message printing to the Irssi SILC client. Added
4186 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4188 * Added SCONNECT command to call the SILC's CONNECT command.
4189 Cannot use CONNECT directly since Irssi uses that internally.
4190 Affected file irssi/src/silc/core/silc-servers.c.
4192 Added ACTION local command. It is same as ME command but takes
4193 the channel as mandatory argument.
4195 Rewrote some of the Irssi's help files to suite for SILC
4198 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Added Makefile.defines[.in] that should for now on be included
4201 in all Makefile.am file in the source tree. That file includes
4202 all common compilation definitions for SILC source tree.
4204 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Minor changes to the ./prepare script to change the package
4207 name according the distribution name to the configure.in.
4209 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Created new distribution system. Added file `distributions'
4212 that defines all the distributions that can be created out of
4213 the SILC source tree. The ./prepare script now reads that
4214 file to determine how to prepare the distributions. The
4215 first argument to the ./prepare is the name of the distribution
4216 and second is the version of the distribution. If given
4217 without arguments it creates the default (toolkit) distribution
4218 with the default version (defined in ./prepare).
4220 All Makefile.am files that are subject to the distributions
4221 are now named as Makefile.am.pre. These are ./Makefile.am
4222 and lib/Makefile.am. Others may be changed later.
4224 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Added invite list, ban list, some key management and connection
4227 error message printing to module formats in the Irssi SILC client.
4229 * Added new silc_client_set_away_message to set the away message
4230 that is back to the person who sent private message. The
4231 affected file lib/silcclient/silcapi.h and the
4232 lib/silcclient/client_prvmsg.c.
4234 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Fixed the private message sending in the Irssi SILC client,
4237 added local command KEY to the Irssi SILC client.
4239 Added key management and key agreement message formats to the
4240 irssi/src/fe-common/silc/module-formats.[ch].
4242 Added USERS (alias WHO) printing, server/router operator
4243 indication and LIST command printing to the module formats.
4245 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Fixed channel joining notify handling, cumode notify handling
4248 from Irssi SILC client.
4250 * Added SILC specific module-formats to the Irssi SILC client so
4251 that SILC specific message hilighting, colors etc is possible.
4252 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4254 Added channel mode, channel user mode, actions, notices,
4255 whois and whowas printing to the the module-formats.c.
4257 * Fixed a bug in channel deletion in the server. The channel
4258 is not left to the cache even if the channel founder auth mode
4259 is set when there are no users anymore on the channel. Affected
4260 file silcd/server.c.
4262 * The silc_net_localhost now resolves the entire hostname including
4263 the domain name. Affected file lib/silcutil/silcnet.c.
4265 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Changed the ask_passphrase client operation to be ascynchronous.
4268 It has now a completion callback and a context that the
4269 application must call after it has got the passphrase from
4270 the user. Affected files lib/silcclient/silcapi.h,
4271 lib/silcclient/protocol.c, lib/silcclient/command.c and
4274 Added SilcAskPassphrase callback that the application calls
4275 to deliver the passphrase to the library.
4277 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4278 The public key verification and especially a certificate
4279 verification is asynchronous procedure.
4281 Added new SILC_SKE_STATUS_PENDING status to indicate the
4282 request is pending and a callback will be called to finalize
4285 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4286 indicate that remote end did not send its public key (or
4287 certificate), even though we require it. Added check for this
4288 condition in the SKE. This was a security bug, now fixed.
4290 Defined new SilcSKEVerifyCbCompletion callback that is called
4291 when the verification process is completed.
4293 The affected files lib/silcske/silcske_status.h and
4294 lib/silcske/silcske.[ch].
4296 * Changed the verify_public_key client operation to be async
4297 as well. Defined SilcVerifyPublicKey callback that is used to
4298 indicate the success of the public key verification process.
4300 Changed the server and client to use the new async client
4303 * Changed the Irssi SILC client's internal scheduler to be called
4304 twice as many times as it used to be. As a result the client
4305 should be a bit faster now. Affected file is
4306 irssi/src/silc/core/silc-core.c.
4308 * Added support to Irssi SILC client of asynchronous public key
4309 verification and passphrase inquiry. Affected file is
4310 irssi/src/silc/core/silc-core.c.
4312 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Do not say "You have left channel %s" in client library.
4315 Moved it to the application. Affected files are
4316 lib/silcclient/command.c and silc/client_ops.c.
4318 * Fixed silc_client_get_clients. Command context was not
4319 duplicated and was freed memory in the callback. Affected
4320 file lib/silcclient/idlist.c.
4322 * Do not say "you are now talking..." on JOIN command in the
4323 client library. The appliation must handle it.
4325 * Do not say ".. changed topic to" in command reply in the
4326 client libary. The application must handle it.
4328 * Fixed TOPIC command sending in the client library.
4330 * Fixed a memory leak in silc_client_command_free in the file
4331 lib/silcclient/command.c.
4333 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Imported a modified version of Irssi client to the source tree.
4336 The Irssi will be used to create a new client called
4337 Irssi SILC. Imported to irssi/.
4339 Added silc_core_init_finish function to the Irssi. Affected
4340 file irssi/configure.in.
4342 A lot changes in the Makefile.ams around the irssi tree.
4344 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Do not rehash if the new size is same as the old size of the
4347 hash table, in the silc_hash_table_rehash*. The affected file
4348 lib/silcutil/silchashtable.c.
4350 * Replaced hash_table_del_by_context calls from the server
4351 (when channel->user_list and client->channels) to the
4352 hash_table_del as it is sufficient and faster.
4354 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Added silc_hash_table_list, silc_hash_table_get and the
4357 SilcHashTableList structure to provide an alternative way to
4358 traverse the hash table. The affected files are
4359 lib/silcutil/silchashtable.[ch].
4361 * Changed the server's idlist routines to use the hash table
4362 routines to optimize the code.
4364 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Replaced the client entry's `channel' list and channel entry's
4367 `user_list' list to hash tables for optimized lookup. Changed
4368 the code to use the hash table interface around the code.
4369 Affected file lib/silcd/idlist.[ch].
4371 * Added `auto_rehash' boolean argument to the function
4372 silc_hash_table_alloc to indicate whether the hash table should
4373 auto-rehash when it thinks is appropriate time. It will
4374 increase the hash table size if the there is twice as much
4375 entries in the table than the size of the table, and will
4376 decrease the size if there are twice as less entries than
4377 the size of the table.
4379 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4383 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * silc_idcache_purge_by_context deletes the entry now by context
4386 as it is supposed to do. Affected file lib/silccore/idcache.c.
4388 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4389 client is not anymore valid (WHOWAS givens the info) and not
4390 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4392 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Removed the `data' and `data_len' arguments from the ID Cache
4395 interfaces and added `name' argument. ID Cache does not handle
4396 anymore the binary data only a names associated with given ID.
4398 * When hashing a Client ID with silc_hash_id the entire ID is
4399 not hashed anymore, instead only the hash of the Client ID is
4400 hashed. This way we can access the Client ID from the cache
4401 with Client ID but with the hash of the ID (which is a hash of
4402 the nickname) as well without any difference in performance.
4404 Added also silc_idcache_find_by_id_one_ext to do one on one
4405 searching when we have the actual ID. Added also function
4406 silc_hash_client_id_compare. The affected files are
4407 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4409 * When hashing the name associated with a ID it is always done
4410 in lowercase. This way we can access the cache without worrying
4411 about case-sensitivity, even though, for example nicknames are
4414 * Fixed a bug in server with channel message sending. It put
4415 wrong ID type as destination ID. The affected file
4416 silcd/packet_send.c.
4418 * silc_idcache_del_by_context now deletes from all hash tables
4419 by context. Affected file lib/silccore/idcache.c.
4421 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Changed the client library to use the new ID Cache interface.
4424 Changes around the source tree.
4426 * Added silc_hash_table_rehash_ext to rehash with specific
4427 hash function. Affected file lib/silcutil/silchashtable.[ch].
4429 * Added silc_hash_string_compare to compare two strings in the
4430 hash table. Affected file lib/silcutil/silcutil.[ch].
4432 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added new function silc_idcache_del_by_context into the
4435 lib/silccore/idcache.[ch].
4437 * Changed the server's ID list routines to use the new ID Cache
4438 interface. Changes around the source tree.
4440 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Added silc_hash_table_del[_by_context]_ext functions in to the
4443 lib/silcutil/silchashtable.[ch].
4445 Removed silc_hash_table_find_all* routines and added new
4446 silc_hash_table_find_foreach to replace them.
4448 Added silc_hash_table_replace_ext function as extended
4449 replacing function. Separated the simple hash table interface
4450 from the extended hash table interface in the file
4451 lib/silcutil/silchashtable.h.
4453 * Fixed minor bugs and changed it to use some of the new
4454 hash table functions in lib/silccore/idcache.c
4456 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Added new function silc_hash_table_find_all to return all keys
4459 in the hash table by the specified key. As the hash table is
4460 collision resistant it also makes it possible to have several
4461 duplicate keys in the hash table. This function may be used to
4462 find all of the keys from the hash.
4464 Added user_context arguments to the SilcHashFunction,
4465 SilcHashCompare and SilcHashDestructor to deliver user specified
4468 Added new fuctions silc_hash_table_find[_all]_ext to do
4469 extended lookup with specified hash and compare functions and
4470 specified user contexts.
4472 Added new function silc_hash_table_add_ext to add the key
4473 with specified hash function and user context.
4475 Added new function silc_hash_table_foreach to traverse all
4476 entrys in the hash table. Added SilcHashForeach callback
4479 Added new function silc_hash_table_del_by_context to delete
4480 the entry only if the context associated with the key matches.
4482 Affected files are lib/silcutil/silchashtable.[ch].
4484 * Removed silc_hash_[server/client/channel]_id and added just
4485 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4486 silc_hash_id_compare to compare two ID's using as the hash table
4487 comparison function. Added also silc_hash_data to hash
4488 binary data and silc_hash_data_compare to compare it.
4490 * Removed silc_idlist_find_client_by_hash as it is not needed
4491 anymore. Affected file silcd/idlist.[ch].
4493 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4494 to use internally the SilcHashTable. The new ID Cache is a lot
4495 faster than the old one. Some of the ID Cache interface was also
4496 rewritten and obsolete and stupid functions were removed.
4498 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Added entry_count field to the SilcHashTable to keep the number
4501 of the entries in the table. Implemented the function
4502 silc_hash_table_rehash. Added new function
4503 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4505 Fixed a minor bug in silc_hash_table_free.
4507 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4508 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4509 into the lib/silcutil/silcutil.[ch].
4511 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Implemented a collision resistant hash table into the
4514 lib/silcutil/silchashtable[ch]. See the header and the source
4515 for the SilcHashTable API.
4517 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Merged dotconf version 1.0.2 into lib/dotconf.
4521 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Do not compile anything in lib/silcsim/* if the SIM support
4524 is not enabled. The tree should now compile without problems
4527 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Compiled the SILC under cygwin. Compiled and tested briefly
4530 without problems. More tests needed. The SIMs didn't compile
4533 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4535 * Fixed possible crash in silc_get_username in the
4536 lib/silcutil/silcutil.c.
4538 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Fixed a va_arg in silc/client_ops.c.
4542 * Oops, RC5 routines were named AES and caused some problems
4543 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4545 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Added new SilcIDIP structure into the lib/silccore/id.h and
4548 replaced the old `ip' fields from all SILC ID's to that type.
4549 This is a step towards IPv6 support.
4551 The silc_id_get_len takes now the ID as an extra argument.
4552 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4553 both IPv4 and IPv6 based ID's.
4555 The affected files are lib/silccore/id.[ch] and other files
4556 around the tree using these routines.
4558 * Removed the ID length arguments in server from various
4559 silc_server_send_notify_* routines -> they are not needed
4562 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Fixed memory leak in silc_encode_pem_file in the file
4565 lib/silcutil/silcutil.c.
4567 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Check minor version as well in the SKE. Affected files are
4570 silcd/protocol.c and lib/silcclient/protocol.c.
4572 * Added --identifier option to the server so that an identifier
4573 can be when creating the public key for the server. Affected
4574 file is silcd/silcd.c.
4576 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4577 lib/silccrypt/silcpkcs.c.
4579 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Register default ciphers and stuff when using -C option with
4582 the server. Affected file sildc/silcd.c.
4584 * Put back the servers public key filename format, it is better
4585 than the new one. For now, the client keys are saved with the
4586 new filename format. The affected file silc/client_ops.c.
4588 * Implemented the Cipher API for the rest of the ciphers that
4589 did not implement it or implemented it the wrong way.
4591 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Register default ciphers and stuff when using the -S option
4594 in the client. Affected file silc/silc.c. Same also when
4595 creating new key pair with -C option.
4597 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Fixed the silc_verify_public_key client operation function to
4600 save the public keys differently. The fingerprint is now
4601 used as filename and not the hostname. This way also the
4602 client keys are saved uniquely and not with hostnames. The
4603 affected file is silc/client_ops.c.
4605 * Trimmed the silc_hash_fingerprint function to remove extra
4606 whitespaces from the end of the fingerprint. The affected
4607 file is lib/silccrypt/silchash.c.
4611 * Added silc_cipher_register_default function to register all
4612 default ciphers. It can be used when configuration files
4613 does not exist and the application does not want any specific
4614 ciphers in any specific order.
4616 The SilcDList is now used as silc_cipher_list dynamically
4617 allocated cipher list. Removed the static list all together
4618 and now all ciphers must be allocated to the dynamic list.
4619 The silc_cipher_alloc routine was changed to check only the
4622 All silc_cipher_* routines that used to return int returns
4625 The affected files lib/silccrypt/silccrypt.[ch].
4627 * The same thing was done to silc_hash_* as for silc_cipher_*
4628 routines. Affected files lib/silccrypt/silchash.[ch].
4630 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4631 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4632 Added also silc_pkcs_[un]register[_default] functions.
4633 Removed the data_context from the PKCS API.
4635 * Added silc_hmac_register_default function to register default
4636 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4637 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4638 to unregister all hmacs at once.
4640 * Register the default ciphers, hash functions, PKCSs and HMACs
4641 if client's configuration file does not exist. The affected
4644 * The client did not load the hash functions from the SIM
4645 modules at all. Added support for this. Affected file is
4646 silc/clientconfig.c.
4648 * When decoding public key with silc_pkcs_public_key_decode, check
4649 the supported algorithm only if PKCS are registered. Affected
4650 file lib/silccrypt/silcpkcs.c. The same was done with the
4651 silc_pkcs_private_key_decode.
4653 * Fixed the SILC List routines to keep the list always in order.
4654 It used to change the list's order when traversing the list but
4655 not it preserves the order. Affected file lib/trq/silclist.h.
4657 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added the client library to use the SilcSocketConnection's
4660 reference counter (by silc_socket_dup) to prevent the bug that
4661 the socket object may be freed underneath async operation.
4663 * The name resolv library checking fixes in the configure.in.pre.
4666 * Created new version of the protocol drafts for future
4667 development. The -03 drafts are the ones that will be changed
4668 in the trunk now and the -02 will remain as they are.
4670 * Send list of CUMODE notifys to the router when announcing
4671 the channel users to the router. Affected file silcd/server.c.
4672 If the router receiving channel founder CUMODE for a channel
4673 that already has channel founder it will send CUMODE notify
4674 to the sender to remove the channel founder rights from the
4675 announced client. Affected file silcd/packet_receive.c.
4677 * The CUMODE notify may now use Server ID as well as the entity
4678 who changes the mode. Updated protocool specs.
4680 * Updated INSTALL and README files.
4682 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * New web pages in the http://silc.pspt.fi. The pages was
4689 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Implemented the [DenyConnectin] config section in the server.
4692 Added silc_server_config_denied_conn to check whether incoming
4693 connection is denied. Affected file silcd/serverconfig.[ch].
4695 * Do not check the ports when checking the incoming configuration
4696 data if the port is 0, meaning any. Affected file is
4697 silcd/serverconfig.c.
4699 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Fixed buffer overflow in silc_string_compare in the file
4702 lib/silcutil/silcutil.c.
4704 * Fixed double free in silc_server_command_leave in the file
4707 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Fixed the version checking in the server. Affected file is
4712 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Fixed the configuration data fetching when accepting new
4715 connections in the server. Affected file silcd/server.c.
4717 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Added `sender_entry' argument to the function
4720 silc_server_packet_relay_to_channel so that we can check
4721 whether some destination actually belongs to the same route
4722 the sender belongs (ie, we must not resend the packet to the
4723 sender). Affected file silcd/packet_send.[ch].
4725 * Added `servername' field to the SilcClientEntry in the server
4726 to hold the name of the server where client is from. Affected
4727 file is silcd/idlist.h.
4729 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Moved the channel message encrypting in the router betwen
4732 router connections from silc_server_channel_message to the
4733 silc_server_packet_relay_to_channel since we want to check
4734 whether we have anybody channel before encrypting anything.
4735 Affected files silcd/packet_[receive/send].c.
4737 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Fixed the [AdminConnection] server config section to support
4740 multiple entries. Affected file silcd/serverconfig.c.
4742 * Added support into the server to check the validity of the
4743 incoming connection before executing any KE or authentication
4746 * The connection configuration is now saved to the KE and
4747 connection auth protocol contexts and not fetched anymore in
4748 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4750 * The local hosts listenning address and port is also resolved
4751 now when starting the server. We want to have the socket object
4752 to include the real address and port for the listener. Added
4753 new function silc_net_check_local_by_sock into the files
4754 lib/silcutil/silcnet.[ch].
4756 * Fixed a broadcast bug in server -> do not broadcast if we
4759 * Fixed a routing bug. Do not route broadcast packets ever.
4760 Broadcast packets must be processed always and not routed since
4761 they may be destined to some other host than yourself and thus
4762 would get routed without no good reason. Affected file is
4765 * Added function silc_server_config_is_primary_route to check
4766 whether primary router connection has been configured (a router
4767 configuration that we are initiating). If there is not, we
4768 will assume that there is only two routers in the SILC network
4769 and we will use the incoming router connection as our primary
4770 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4772 * Changed the order of the broadcasting. Broadcast _after_ the
4773 packet has been processed not before. Affected file is
4776 * Fixed a [ClientConnection] parsing bug. The port was never
4777 parsed correctly thus resulting to port 0. Affected file
4778 silcd/serverconfig.c.
4780 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4781 argument and did not set the broadcast packet flag. Affected
4782 file silcd/packet_send.c. Fixed same bug in the function
4783 silc_server_send_notify as well.
4785 * If we receive NEW_ID packet for our own ID in the server, ignore
4788 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Removed the nickname from the Private Message Payload.
4793 Updated the code and the protocol specs.
4795 * Updated protocol specs for submitting to the IETF.
4797 * Tweaked the Random Number Generator a bit. Affected file
4798 lib/silccrypt/silcrng.c. Exported a new function
4799 silc_rng_[global]_add_noise which can be used to add more
4802 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Do not parse packets with different timeout when protocol
4805 is active -> may cause problem with rekey. Affected file
4808 * When server receives signoff notify it must not create
4809 new channel key if the client is on any channels since the
4810 sender of the signoff notify will create it.
4812 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Added printing of error messages during SKE protocol from the
4815 failure packet sent by server during SKE. Affected file
4818 * Removed the client's failure_callback handling with timeout
4819 and handle it immediately when received.
4821 * The SKE library returned wrong type in SUCCESS and FAILURE
4822 packets. They must be 32 bit MSB not 16 bit MSB.
4824 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Ok, rewrote the logic of the re-key and now it seems to work.
4827 I tested it on high traffic with frequent re-keys without
4828 problems. Added hmac_receive (and renamed hmac to hmac_send)
4829 in SilcClientConnection in lib/silcclient/client.h and
4830 in SilcIDListData in silcd/idlist.h. Also, removed the
4831 SilcPacketParserContext's cipher and hmac fields as they are
4832 not needed anymore and actually caused some problems when
4833 the ciphers and hmac's changed underneath the packet parser.
4835 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * If re-key protocol is active then process the incoming packets
4838 synchronously since we must assure that icoming packets encrypted
4839 with the old key is processed before the new keys is set to
4840 use. This is true other packets than for REKEY packets.
4841 Affected file silcd/server.c. The same was done to client library
4842 as well, affected file lib/silcclient/client.c.
4844 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Fixed bug in client and server to accept the force send if
4847 the packet is send from silc_[server/client]_packet_process
4848 function. Otherwise the packets are never delivered, oops.
4850 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Disable force sending of packets when REKEY protocol is active.
4853 We must assure that no packet is sent directly when rekey is
4854 performed. All packets must be sent through packet queue.
4855 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4856 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4857 function is silc_[server/client]_packet_send_real to check
4860 * Replaced the SIM paths from example config files to
4861 /usr/local/modules. Also, make install creates now
4862 /usr/local/silc/logs directory to hold all the SILC server
4865 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4867 * Made the configure.in.pre work on Solaris. Patch by salo.
4869 * Made all ciphers compatible with non-x86 machines. Defined
4870 CBC mode macros into lib/silccrypt/ciphers_def.h.
4872 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Fixed the make install.
4876 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * When MAC computation fails the silc_packet_decrypt returned 0
4879 even though it was supposed to return -1. Fixed this. The
4880 affected file is lib/silccore/silcpacket.c.
4882 * Do not replace the config files in /etc/silc (in make install)
4883 if they already exist. Affected file ./Makefile.am.
4885 * Do not send re-key packets immediately but through packet queue.
4886 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4888 * Changed silc_net_check_host_by_sock to return FALSE if the
4889 IP/DNS could not be resolved. Though, it returns the IP address
4890 now even if it could not resolve it (but returns also FALSE).
4891 Affected file lib/silcutil/silcnet.[ch].
4893 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Added silc_pkcs_decode_identifier to decode the public key's
4896 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4897 Added also silc_pkcs_free_identifier. Added also new context
4898 SilcPublicKeyIdentifier.
4900 * Added -S option to the silc client. It is used to dump the
4901 contents of the specified public key file.
4903 * Changed the PKCS api to return the public key length when
4904 setting the public key.
4906 * Fixed a fatal bug in the public and private key file loading.
4907 Affected file lib/silccrypt/silcpkcs.c.
4909 * Execute the packet parsing for client with zero (0) timeout
4910 if the protocol is active. Affected file silcd/server.c.
4912 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Made the key generation options to the silcd program. Added
4915 -C option, equivalent to client's option.
4917 * Added new [ServerKeys] config section to the server. It
4918 configures the server's public and private key.
4920 * Defined generic Public Key Payload into the protocol
4921 specification to send specific type of public keys and
4924 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4925 public key or certificate.
4927 * Implemented the GETKEY command to the server and to the
4928 client library and on user interface.
4930 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Made preliminary `make install' work.
4934 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Added SilcServerRekey context into silcd/idlist.h.
4938 * Added the PFS support as defined in the specification to the
4939 SKE protocol. Affected files lib/silcske/*.c.
4941 * Added `ske_group' field to the SilcServerRekey context to hold
4942 the number of the SKE group that is used with PFS in re-key.
4943 Affected file silcd/idlist.h.
4945 * Added PFS re-key support to the server. Affected file is
4948 * Added silc_protocol_cancel to cancel execution of the next
4949 state of the protocol. Affected file is
4950 lib/silccore/silcprotocol.[ch].
4952 * Added the re-key support with and without PFS to the client
4953 library. Re-key is performed once in an hour, by default.
4955 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4956 Added silc_client_rekey_callback and silc_client_rekey_final.
4957 Affected files are lib/silcclient/protocol.[ch] and
4958 lib/silcclient/client.[ch].
4960 * Removed the `hmac_key' and `hmac_key_len' fields from the
4961 SilcClientConnection structure; not needed. Affected file is
4962 lib/silcclient/client.h.
4966 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Do not ask whether user wants to use the negotiated private key
4969 for private messages, just use it. Affected file is
4970 silc/local_command.c.
4972 * Added `send_enc_key' and `enc_key_len' fields to the
4973 SilcIDListData structure since they are needed in the re-key
4974 phase. Affected file is silcd/idlist.[ch].
4976 * Implemented the simple re-key protocol into the server.
4977 Affected files silcd/server.c and silcd/protocol.[ch]. The
4978 re-key will be performed once in an hour, by default.
4980 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4981 Added silc_server_rekey, silc_server_rekey_callback and
4982 silc_server_rekey_final.
4984 * Removed Tunneled flag from the protocol. Updated the code
4985 and the specifications.
4987 * Adde `pfs' field to the SilcIDListData to indicate whether
4988 the PFS is to be performed in the re-key. Affected file is
4991 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4994 int64 of at least the xintXX size. If void * is less that 4
4995 bytes uint32 * will be used. Defined bool as boolean.
4997 * Changed _ALL_ unsigned long and unsigned int to uint32,
4998 unsgined short to uint16 in the source tree.
5000 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5001 not handle clients that has entry->data.registered == FALSE.
5002 They are not in the network anymore. Affected file is
5005 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Implemented the sending of the SERVER_SIGNOFF notify in the
5008 server. Affected file is silcd/server.c.
5010 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5011 Added also silc_notify_payload_encode_args into the
5012 lib/silccore/silcnotify.[ch].
5014 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5015 Affected file silcd/packet_receive.c.
5017 * Implemented the SERVER_SIGNOFF notify handling in the client
5018 library. Affected file lib/silcclient/client_notify.c. Also,
5019 implemnted the printing of the SERVER_SIGNOFF info to the
5020 application. Affected file silc/client_ops.c.
5022 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5023 if the deleting was successful. Affected file silcd/idlist.[ch].
5025 * Added support for public key authentication in the connection
5026 authentication protocol in the client library. Affected file
5027 lib/silcclient/protocol.c.
5029 * Changed the server's silc_idlist_get_clients_by_* interface
5030 to support already allocated array so that new entries may be
5031 added to pre-allocated array. Affected file silcd/idlist.[ch].
5032 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5033 and command replies.
5035 * All command reply functions in the server now calls the
5036 pending command callback even if error occured. This way the
5037 error will be delivered to the client as well. Affected files
5038 silcd/command.c and silcd/command_reply.c.
5040 * Fixed INFO command to return local server's info if no server
5041 was provided. Affected file lib/silcclient/command.c.
5043 * Removed RESTART command for good. Updated the code and the
5046 * Rewrote parts of the task system. It is a bit simpler now.
5047 Removed unsued task priorities. The affected files are
5048 lib/silcutil/silctask.[ch].
5050 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Moved the USERS printing from the library to the application.
5053 Affected files lib/silcclient/command.c and silc/client_ops.c.
5055 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Added channel key re-key support. The re-key is perfomed
5060 only by the router and is done once in an hour. Added `rekey'
5061 field to the SilcChannelEntry in the server. Affected files
5062 silcd/server.c and silcd/idlist.h.
5064 * Added silc_task_unregister_by_context into the file
5065 lib/silcutil/silctask.[ch].
5067 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Added SILC_UMODE_GONE mode to indicate when the client is not
5070 present in the SILC network. Added also support to the local
5071 command AWAY that will set this mode. Added support of showing
5072 "xxx is gone" in WHOIS command. The USERS command shows the
5073 gone status as well.
5075 * Fixed setting server and router operator privileges in the
5076 server's UMODE command. Affected file silcd/command.c.
5078 * Merged the SKE KE1 and KE2 payloads into one payload. The
5079 new KE payload is equivalent to the old KE2 payload.
5081 Cleaned up the SKE Start Payload parsing. It now uses the
5082 simple buffer unformatting to do the parsing. A lot faster
5085 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5086 to the SKE that is used to indicate whether both of the SKE
5087 parties should perform authentication. By default only the
5088 responder performs authentication. By setting this flag also
5089 the initiator must do authentication. By default it is unset
5090 since in normal SKE case, client to server connection, only
5091 the responder should do authentication. When doing SKE between
5092 two clients both should perform authentication. Updated the
5093 code and the protocol specs.
5095 * A little fix to IDENTIFY command in the server. Search the
5096 client first by hash not nickname. Affected file is
5099 * Fixed the silc_client_close_connection to support closing
5100 the client to client connections wihtout deleting too much
5101 data. Affected file lib/silcclient/client.c.
5103 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5104 are received if protocol used to be active but is not anymore
5105 the application would crash due to NULL pointer dereference.
5106 Affected files silcd/server.c and lib/silcclient/client.c.
5108 * Added `hash' field to the SilcClientConnection to include
5109 the hash function negotiated in the SKE protocol.
5111 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5112 to set the channel founder authentication data. A client can
5113 claim the founder rights later by providing the authentication
5114 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5115 This way the channel founder can regain the channel founder
5116 privileges even it is left the channel. This works only on
5117 local server and the client must be connected to the same
5118 server to be able to regain the founder rights. Updated the
5119 protocol specs accordingly.
5121 Added support to the CMODE command in the client to set the
5122 founder auth data. Read the README to see how to set it.
5124 Added support to the CUMODE command to claim the founder
5125 rights. Read the README to see how to do it.
5127 Added support for the founder authentication to the Channel
5128 Entry in the server. Affected file silcd/idlist.h.
5130 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5131 server's CMODE command. Affected file silcd/command.c.
5133 * Added the following new functions into lib/silccore/silcauth.[ch]:
5134 silc_auth_get_method and silc_auth_get_data.
5136 * The server now saves the remote hosts public key to the
5137 SilcIDListData pointer. Affected file silcd/protocol.c.
5139 * The normal server now does not remove the channel entry from
5140 the cache if the founder authentication data is set. It used
5141 to remove it if the founder was the last one on the channel on
5142 the server and left the channel. The auth data is saved and
5143 if the channel is re-joined later the old entry is used with
5144 the old auth data. Affected files silcd/command_reply.c and
5147 * Removed the `pkcs' field from the SilcIDListData structure
5148 in the server; it is not used. Affected file silcd/idlist.h.
5150 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Fixed packet processing on slow links. Partial packets were
5153 never re-processed because the incoming data buffer was cleared
5154 by the application. Application must not directly clear the
5155 sock->inbuf, the packet processing routines handle it. Fixed
5156 this in client library and in server.
5158 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Fixed the WHOIS and IDENTIFY send reply function to really
5161 check whether to send list or just one entry. Affected file
5164 * Cleaned up the LEAVE command's channel key distribution. The
5165 affected file silcd/command.c.
5167 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5168 can enforce the channel mode as well. In that case the ID
5169 includes the ID of the server. The code now enforces the
5170 mode change if the router have different mode than the server.
5172 * The notify client operation with CMODE_CHANGE notify can now
5173 return NULL client_entry pointer if the CMODE was not changed
5174 by client. Application must check for this.
5176 * Added <Server ID> argument to INFO command to support server
5177 info fetching by Server ID.
5179 * Added silc_server_announce_get_channel_users to get assembled
5180 packets of channel users of the specified channel. Affected
5181 file silcd/server.[ch].
5183 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5184 was freed underneath the ID Cache.
5186 * Re-announce clients when the server received CHANNEL_CHANGE
5187 notify from the router. Affected file silcd/packet_send.c.
5189 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5192 crashed since it did not handle the fact that there is no cipher
5193 called "3" and didn't check the error condition. Now fixed.
5195 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5196 flag. It can be used to send message requests.
5198 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Implemented the RESTART command in the client.
5202 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5203 notice type messages. Added notice printing to the user
5206 * The channel keys are not re-generated if the channel's mode
5207 is PRIVKEY, ie private key on the channel exists. Affected
5208 files silcd/server.c and silcd/command.c.
5210 * Fixed a little bug in channel message delivery when channel
5211 private keys are set in the server. Affected file is
5212 silcd/packet_send.c.
5214 * Changed the setting on channel->on_channel = TRUE from the
5215 silc_client_save_channel_key to the JOIN command reply. The
5216 key payload is not received if the private channel key is set.
5217 Affected file lib/silcclient/command_reply.c and the
5218 lib/silcclient/client_channel.c.
5220 * When the CMODE_CHANGE notify is sent and the channel private
5221 key mode is removed the channel key must be re-generated in
5222 other cells as well. Added this support for the router in the
5223 silcd/packet_receive.c.
5225 * Added new local command NOTICE to send notice message on
5226 channel. Affected file silc/local_command.[ch].
5228 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Added new local command ME to the client. It is used to send
5231 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5232 some action. Affected file silc/local_command.[ch].
5234 * Changed channel_message and private_message client operations
5235 to deliver the message flags to the application. Added also
5236 the `flags' arguments to the silc_client_send_channel_message
5237 and silc_client_send_private_message functions. Affected file
5240 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Redefined the Private Message Payload to support private message
5243 keys and to support the new private message flags. Updated
5244 the protocol specs. Flags makes it possible to have for example
5245 CTCP style messages.
5247 * Added new type SilcPrivateMessagePayload and defined an API
5248 for it in the lib/silcclient/silcprivate.[ch].
5250 * Tested private message private keys successfully. Tested the
5251 private message key set, unset and list commands with the new
5254 * Redefined the Channel Message Payload to include the channel
5255 message flags (equal with private message flags) to support
5256 for example CTCP style messages.
5258 * Defined some of the message (for channel and private message)
5259 flags. Updated the protocol specs and added the flags to the
5260 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5262 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added SilcKeyAgreementStatus type to the key agreement routines
5265 to indicate the current status and error if one occured.
5266 The status types are defined in the lib/silcclient/silcapi.h.
5268 * Added new local command KEY that is used to set and unset private
5269 keys for channels, set and unset private keys for private messages
5270 with remote clients and to send key agreement requests and
5271 negotiate the key agreement protocol with remote client. The
5272 key agreement is supported only to negotiate private message keys,
5273 it currently cannot be used to negotiate private keys for channels,
5274 as it is not convenient for that purpose.
5276 * Fixed a minor pending callback setting bug in the function
5277 silc_client_get_client_by_id_resolve, now the function works.
5278 Affected file lib/silcclient/idlist.c.
5280 * Added function silc_net_get_local_port to get local bound
5281 port by socket. Added to lib/silcutil/silcnet.[ch].
5283 * Added `sockets' and `sockets_count' fields to the SilcClient
5284 object. They hold the sockets of the listenning sockets in
5285 the client. Listenning sockets may be for example the key
5286 agreement server. Affected file lib/silcclient/client.[ch].
5287 Added functions the silc_client_add_socket and the
5288 silc_client_del_socket. They are exported to the application
5291 * Added ~./silc/clientkeys to support other client's public keys.
5293 * Renamed verify_server_key client operation to verify_public_key
5294 and added one argument to indicate the type of the connection
5295 (server, client etc.).
5297 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Added silc_server_connection_auth_request to handle the
5300 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5301 silcd/packet_receive.[ch].
5303 * Added silc_server_send_connection_auth_request into the
5304 silcd/packet_send.c to send the connection auth request packet.
5306 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5309 * Fixed the public key authentication in responder side in the
5310 server. The `auth_data' pointer includes the SilcPublicKey
5311 not the path to the public key. Affected file silcd/protocol.c.
5313 * Implemented the public key authentication in the initiator side
5314 in the server. Affected file silcd/protocol.c.
5316 * Removed the [RedirectClient] config section from the server
5317 configuration. Is not needed and I don't want to implement it.
5319 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Cleaned up the CMODE command in the server. It now works
5322 correctly and supports all the modes defined in the protocol.
5323 Affected file is silcd/command.c.
5325 * Added `hmac_name' field to the SilcChannelEntry in the server
5326 to hold the default HMAC of the channel. It can be set when
5327 creating the channel (with JOIN command). Affected files
5330 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5331 type to indicate the change of the current cipher and hmac
5332 on the channel. Client can safely ignore the <cipher> argument
5333 (if it chooses to do so) since the CHANNEL_KEY packet will
5334 force the channel key change anyway. The <hmac> argument is
5335 important since the client is responsible of setting the new
5336 HMAC and the hmac key into use.
5338 * Fixed the CMODE command in the client library as well.
5340 * Tested CMODE command in router environment successfully.
5342 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Show the version of the remote client (or server) when connecting
5345 to the server. It is logged to the log file. Affected file
5346 is silcd/protocol.c.
5348 * Fixed the KILLED notify handling in the client library. The
5349 client must be removed from all channels when receiving the
5352 Also, do not remove the client entry when giving the KILL
5353 command but when the KILLED notify is received.
5355 * Removed silc_idlist_find_client_by_nickname from the server.
5356 Not needed anymore. Affected files silcd/idlist.[ch].
5358 * Implemented the CHANNEL_CHANGE notify type handling to the
5359 server. Affected file silcd/server.c.
5363 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Added silc_server_send_notify_invite to send the INVITE
5366 notify between routers.
5368 * Implemented the INVITE command correctly to the server.
5370 * Implemented the INVITE notify type handling in the server.
5372 * Implemented the INVITE command to the client library and on the
5375 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Added function silc_server_get_client_resolve to find the
5378 client entry by ID from all ID lists and then resolve it
5379 (using WHOIS) if it cannot be found. Affected file is
5382 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5384 * Implemented the BAN command to the client library.
5386 * The JOIN command in the server now checks the invite list
5389 * Changed the silc_command_reply_payload_encode_va and the
5390 silc_command_payload_encode_va to support that if argument is
5391 NULL it ignores and checks the next argument. Affected file
5392 lib/silccore/silccommand.c.
5394 * Added silc_server_send_notify_ban to send the BAN notify
5395 type between routers.
5397 * Chaned the silc_notify_payload_encode to support that if
5398 argument is NULL it ignores and checks the next argument.
5399 Affected file lib/silccore/silcnotify.c.
5401 * Tested ban lists in router environment successfully.
5403 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Implemented BAN command to the server, in silcd/command.[ch].
5407 * Removed the BAN and INVITE_LIST modes from the CMODE command
5410 * Added function silc_string_match to regex match two strings.
5411 Affected files lib/silcutil/silcutil.[ch].
5413 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Redefined parts of the SilcChannelEntry in the server to support
5416 the new ban and invite lists.
5418 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Redefined the INVITE command. The same command can be used to
5421 invite individuals to the channel but also to manage the invite
5422 list of the channel (to add to and remove from the invite list).
5423 Updated the protocol specs.
5425 * Added new command SILC_COMMAND_BAN that can be used to manage
5426 the ban list of the channel. Updated the protocol specs.
5428 * Removed the channel modes: the SILC_CMODE_BAN and the
5429 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5430 in the CMODE command. The equivalent features are now available
5431 using INVITE and BAN commands. Updated the protocol specs.
5433 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5434 in the network about change in the current ban list. The notify
5435 type is not used by the client.
5437 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5438 support the invite lists.
5440 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Added new function silc_string_regexify that converts string
5443 including wildcard characters into regex string that can
5444 be used by the GNU regex library. Added into the file
5445 lib/silcutil/silcutil.[ch].
5447 Added silc_string_regex_combine to combine to regex strings
5448 into one so that they can be used as one regex string by
5449 the GNU regex library. Added into the file
5450 lib/silcutil/silcutil.[ch].
5452 Added silc_string_regex_match to match two strings. It returns
5453 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5455 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Imported GNU regex to the soruce tree into lib/contrib.
5458 Fixed some compiler warning from the regex.c.
5460 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Fixed MOTD command in the server to work in router environment.
5464 * Fixed the MOTD command in the client library to support
5465 the server argument in the command.
5467 * Added `nickname_len' argument to the silc_idlist_add_client
5468 in the server, as the `nickname' argument may be binary data
5471 * Added silc_idlist_get_channels to return all channels from
5474 * Implemented LIST command to the server. Affected file is
5477 * Implemented the LIST command to the client library and on the
5480 * Added [<user count>] argument to the LIST command reply.
5481 With private channels the user count is not shown.
5483 * Updated TODO and README.
5485 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * The client entry's data.registered must be TRUE even with
5488 global client entry on global client list. The data.registered
5489 is used to check whether the client is anymore in the network,
5490 for example with WHOWAS command so it must be valid.
5492 * Fixed the WHOWAS command in the server. It now actually works
5493 in router environment. Added function into silcd/command_reply.c
5494 silc_server_command_reply_whowas_save.
5496 * Added silc_idlist_purge function to the silcd/idlist.c
5497 to periodically purge the ID Cache.
5499 * Fixed INFO command in the server. It works now in router
5500 environment. Added <server name> argument to the INFO command
5501 reply. Updated the protocol specs.
5503 * Fixed minor bug in silc_idcache_purge to not purge if the
5504 expire value is zero.
5506 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5507 they were buggy because of the WHOWAS information.
5509 * Fixed local command MSG to handle the async resolving of
5510 the remote client properly. It used to fail the first MSG.
5511 Affected file silc/local_command.c.
5513 * Added `data_len' field to SilcIDCache context.
5515 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Update TODO. Todo in commands in the server.
5519 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5522 used by routers as broadcast packet to inform other routers
5523 about the changed user mode.
5525 Implemented the notify handling in the server. Affected file is
5526 silcd/packet_receive.c. Added the function
5527 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5529 * Added new generic Channel Payload and deprecated the New Channel
5530 Payload. The New Channel Payload is now the generic Channel
5533 * Added new argument `mode' to the silc_server_send_new_channel
5534 as it is required in the Channel Payload now.
5536 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5537 and created a new and real SilChannelPayload to represent the
5538 new generic Channel Payload. Implemented the encode/decode
5539 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5541 * Added silc_server_get_client_channel_list to return the list
5542 of channels the client has joined for WHOIS command reply.
5543 Affected file silcd/server.[ch].
5545 * Implemented the channel list sending in the WHOIS command reply
5546 in server and in the client.
5548 Implemented the channel list displaying on the user interface
5549 as well. Affected file silc/client_ops.c.
5551 * Added silc_channel_payload_parse_list to parse list of Channel
5552 Payloads. It returns SilcDList list of SilcChannelPayloads.
5553 Client for example can use this function to parse the list of
5554 channels it receives in the WHOIS command reply. The caller
5555 must free the list by calling silc_channel_payload_list_free.
5556 Affected files lib/silccore/silcchannel.[ch].
5558 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Added one new argument <user mode> to the WHOIS command reply
5561 to return the mode of the user in SILC. Updated the protocol
5564 Implemented it to the server and client.
5566 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Fixed the mode printing on the user interface on joining.
5569 Affected file silc/client_ops.c.
5571 * Implemented the UMODE command and user modes in general to the
5572 client library and to the user interface.
5574 * Implemented the UMODE command to the server.
5576 * The server now sends UNKNOWN_COMMAND error status if client sends
5577 unknown command. Affected file silcd/command.c.
5579 * All server commands now handle the command identifier the right
5580 way when sending the command reply to the client. The client can
5581 use to identify the command replies with the identifier.
5583 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added silc_server_get_client_route to resolve the route to
5586 the client indicated by the client ID. Affected file is
5589 * Added silc_server_relay_packet as general function to relay
5590 packet to arbitrary destination. This deprecates functions
5591 like _send_private_message_key, _relay_notify etc. Affected
5592 file is silcd/packet_send.[ch].
5594 Removed silc_server_send_key_agreement,
5595 silc_server_send_private_message_key and
5596 silc_server_packet_relay_notify functions from the file
5597 silcd/packet_send.[ch].
5601 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5602 server. Affected file silcd/packet_receive.[ch].
5604 * Implemented the KILL command to the client. Implemented the
5605 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5606 Affected files lib/silcclient/command[_reply].c and
5607 lib/silcclient/client_notify.c. Implemented the KILL notify
5608 printing in the user inteface.
5610 * Fixed a lot silc_parse_nick memory leaks from the client
5611 library in the file lib/silcclient/command.c.
5613 * Changed the silc_server_send_notify_on_channels's `sender'
5614 argument from SilcSocketConnection to SilcClientEntry to
5615 check the sender as entry and not as connection object and not
5616 to send to the client provided as argument. The affected file
5617 is silcd/packet_send.[ch].
5619 * The notify packets that are destined directly to the client used
5620 to not to be processed by the server. Now changed that and the
5621 server processes all notify packets. After relaying the packet
5622 to the client the notify packet is processed in the server.
5624 * The silc_server_free_client_data now checks whether there is
5625 pending outgoing traffic for the client and purges the data to
5626 the network before removing the client entry.
5628 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5631 an client is killed from the SILC Network. Updated the protocol
5634 Added new function silc_server_send_notify_killed to the
5635 silcd/packet_send.[ch].
5637 * Added function silc_server_packet_relay_notify to relay notify
5638 packets that are destined directly to a client. In this case
5639 the server does not process the notify packets but merely relays
5640 it to the client. Affected file silcd/packet_send.[ch].
5642 Added also silc_server_packet_process_relay_notify to check
5643 whereto relay the notify. Affected file is
5644 silcd/packet_receive.[ch].
5646 * Implemented the KILL command to the server.
5650 * Added the backup schema desgined last fall to the protocol
5651 specs for everyone to see. The specification is in the
5652 *-spec-xx.txt draft and the packet type definitions for the
5653 backup routers is in *-pp-xx.txt draft. Thusly, added also
5654 new packet type SILC_PACKET_CELL_ROUTERS.
5656 * A big security problem in the implementation discovered. The
5657 signoff of an client did not cause new channel key generation
5658 which it of course should've done. The channel keys must be
5659 always re-generated when client leaves (or signoffs) the channel.
5660 The silc_server_remove_from_channels funtion now handles
5661 the channel key re-generation.
5663 * Added `sender' argument to the silc_server_send_notify_on_channels
5664 to not to send the client provided as argument. Affected file
5665 silcd/packet_send.[ch].
5667 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Implemented OPER and SILCOPER commands into the server and
5672 * Added silc_auth_verify and silc_auth_verify_data to verify
5673 the authentication directly from the authentication payload.
5674 It supports verifying both passphrase and public key based
5675 authentication. Affected file lib/silccore/silcauth.[ch].
5677 * Added `hash' field to the SilcIDListData structure. It is the
5678 hash negotiated in the SKE protocol. Affected file is
5681 * Slight redesigning of the SilcAuthPayload handling routines.
5682 Do not send SilcPKCS but SilcPublicKey as argument.
5684 * Implemented the public key authentication support to the
5685 serverconfig. The public key is loaded from the provided path
5686 and saved as authentication data to void * pointer. Thus,
5687 changed the unsigned char *auth_data to void *auth_data;
5689 * Fixed SHUTDOWN command to send the reply before the server
5690 is shutdown. :) Affected file silcd/command.c.
5692 * Fixed fatal bug in CONNECT command. The hostname was invalid
5693 memory and server crashed. Affected file silcd/command.c.
5695 * Fixed fatal bug in CLOSE command. The server_entry became
5696 invalid but was referenced later in the command. Affected file
5699 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5701 * Fixed fatal bug in failure packet handling. Server ignored
5702 the failure and thus crashed when it came.
5706 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5709 that the command may be executed only once in (about) 2 seconds.
5710 The old SILC_CF_LAG flag is same but allows command bursts up
5711 to five before limiting.
5713 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5714 server code. Various commands now includes the CF_LAG_STRICT
5715 flag to disallow any kind of miss-use of the command.
5717 * Fixed the silc_buffer_unformat to not to allocate any data
5718 if the length of the data is zero. It used to allocate the
5719 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5721 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Changed the format of AdminConnection configuration section
5724 in the server. Added username of the admin to the format.
5725 Affected files silcd/serverconfig.[ch].
5727 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5728 to return admin configuration data by host, username and/or
5731 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Implemented WHOWAS command to the server. Added the functions:
5735 silc_server_command_whowas_parse,
5736 silc_server_command_whowas_send_reply,
5737 silc_server_command_whowas_from_client and
5738 silc_server_command_whowas_from_server
5740 * Added <Client ID> argument to the WHOWAS command reply. Updated
5741 the protocol specs accordingly.
5743 * Implemented WHOWAS command and command_reply to the client
5746 Implemented the WHOWAS printing on the user interface.
5748 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Added new argument to the WHOWAS command reply, the real name.
5751 It is an optional argument. Updated the protocol specs.
5753 * Added SilcIDCacheDestructor callback that is registered when
5754 the SilcIDCache is allocated. The callback is called when
5755 an cache entry in the ID Cache expires, or is purged from the
5756 cache. Added into lib/silccore/idcache.[ch].
5758 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5759 to destruct the client entries when the cache entry expires.
5760 Other ID Cache's in server and in the client library ignores
5763 * If the ID Cache entry's `expire' field is zero then the entry
5764 never expires. Added boolean `expire' argument to the
5765 silc_idcache_add function in the lib/silccore/idcache.[ch].
5766 If it is TRUE the default expiry value is used.
5768 * Added silc_server_free_client_data_timeout that is registered
5769 when client disconnects. By default for 5 minutes we preserve
5770 the client entry for history - for WHOWAS command.
5772 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added support to the server to enforce that commands are not
5775 executed more than once in 2 seconds. If server receives
5776 commands from client more frequently, timeout is registered
5777 to process the commands. Affected file silcd/command.c.
5778 Added new function silc_server_command_process_timeout.
5780 * Changed NICK_NOTIFY handling in client library to check that
5781 if the client's nickname was changed, so there is no need to
5782 resolve anything from the server.
5784 * Removed error printing from the WHOIS and IDENTIFY commands.
5785 If error occurs then it is ignored silently in the client library.
5786 The application, however, may map the received error to
5787 human readable error string. The application currently maps
5788 the NO_SUCH_NICKNAME error to string.
5790 * Made the command status message public to the application. Moved
5791 them from lib/silcclient/command_reply.c to
5792 lib/silcclient/command_reply.h. The application can map the
5793 received command status to the string with the
5794 silc_client_command_status_message function.
5796 * Added check to the server to check that client's ID is same
5797 as the Source ID in the packet the client sent. They must
5800 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Added dist-bzip hook to the Makefile.am to make bzip2
5803 compressed distributions.
5805 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Server now enforces the maximum length for the nickname and
5808 the channel as protocol specification dictates. 128 bytes for
5809 nickname and 256 bytes for channel name.
5811 * Moved the WHOIS printing to the application. The client libary
5812 does not print out the WHOIS information anymore, the application
5813 must do it. Renamed silc_client_command_reply_whois_print to
5814 the silc_client_command_reply_whois_save.
5816 The client's idle time is also sent to the application now, and
5817 the idle is shown on screen.
5819 * Added silc_client_command_reply_identify_save to save the
5820 received IDENTIFY entries.
5822 * Do not check for channel private keys in message sending and
5823 reception if the channel does not have the PRIVKEY mode set.
5824 Affected file lib/silclient/client_channel.c.
5826 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5829 just surfaced after chaning the JOIN procedure.
5831 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Added silc_client_get_clients_by_list to get client entries
5834 from Client ID list, that is returned for example by JOIN
5835 and USERS command replies. The application should use this
5836 function for example when JOIN command reply is received to
5837 resolve the clients already on the channel (library does not
5838 do that anymore as USERS command reply is not used in the JOIN
5839 procedure anymore). Affected files lib/silcclient/silcapi.h and
5840 lib/silcclient/idlist.c.
5842 * JOIN command reply and USERS command reply returns now SilcBuffer
5843 pointers instead of unsigned char pointers when returning
5844 the client list and mode list.
5846 * Added <Client ID> argument to the JOIN command reply, mainly
5847 for the server to identify for which client the command was
5848 originally sent. Updated protocol specs accordingly.
5850 * Added SilcDlist private_key pointer to the SilcChannelEntry
5851 in the client to support the channel private keys. Affected
5852 file is lib/silcclient/idlist.h.
5854 * Added SilcChannelPrivateKey argument to the function
5855 silc_client_send_channel_message so that application can choose
5856 to use specific private ke if it wants to. If it is not provided,
5857 the normal channel key is used, unless private keys are set.
5858 In this case the first (key that was added first) is used
5859 as the encryption key.
5861 * Implemented the support for channel private key handling.
5862 Implemented the following functions:
5864 silc_client_add_channel_private_key,
5865 silc_client_del_channel_private_keys,
5866 silc_client_del_channel_private_key,
5867 silc_client_list_channel_private_keys and
5868 silc_client_free_channel_private_keys
5870 Affected file lib/silcclient/client_channel.c.
5872 * Added the support for the private keys in the channel message
5873 sending and encryption and in the message reception and
5874 decryption. Affected funtions are
5875 silc_client_send_channel_message and silc_client_channel_message.
5877 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added SKE's key verify callback to the client library's
5880 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5882 * Removed the statement that server (or router) must send USERS
5883 command reply when joining to the channel so that the client
5884 knows who are on the channel. Instead, the client list and
5885 client's mode list is now sent in the JOIN command reply to the
5886 client who joined channel. This is better solution.
5888 * Added function silc_server_get_users_on_channel and function
5889 silc_server_save_users_on_channel to the silcd/server.[ch].
5891 * Removed function silc_server_command_send_users from the
5894 * Do not show topic on the client library anymore. The topic is
5895 sent in the command reply notify to the application and the
5896 application must show the topic now.
5898 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Added client searching by nickname hash into the IDENTIFY and
5901 WHOIS commands in the server as they were clearly missing from
5902 them. Affected file is silcd/command.c.
5904 * Fixed a bug in private message receiving in the client library.
5905 The remote ID was freed and it wasn't supposed, now it is
5908 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Minor fix to the channel payload; allocate the data area, as it
5911 needs to be of specific length.
5913 * If the key agreement port is zero then the operating
5914 system will define the bound port. Affected files are
5915 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5917 * Added new function silc_channel_payload_decrypt into the file
5918 lib/silccore/silcchannel.[ch].
5920 * Moved the channel message etc, check from silc_packet_decrypt
5921 to applications. The library calls now a generic
5922 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5923 when the packet is either normal or special. This was done to
5924 allow more wide range of checking that was not allowed when
5925 the code was in library. Now applications can do virtually any
5926 checks to the packet and return to the library the decision how
5927 the packet should be processed. Affected files are
5928 lib/silccore/silcpacket.[ch].
5930 Added silc_server_packet_decrypt_check to the server and
5931 silc_client_packet_decrypt_check to the client library.
5933 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5934 to send with specified source and destination information.
5936 * Channel message delivery between routers was broken after the
5937 channel key distribution was fixed earlier. The channel key
5938 was used be to distributed to other routers as well which is not
5939 allowed by the protocol. Now this is fixed and channel keys
5940 really are cell specific and the channel message delivery between
5941 routers comply with the protocol specification.
5943 * Fixed various commands in server to check also the global list
5944 for the channel entry and not just the local list. The affected
5945 file silcd/command.c.
5947 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Added assert()s to buffer formatting and unformatting routines
5950 to assert (if --enable-debug) when error occurs. Affected
5951 file: lib/silcutil/silcbuffmt.c.
5953 * Changed to auto-reconnect to check whether the remote host is
5954 router and register the re-connect timeout if it is. It used
5955 to check that whether we are normal server, but router must do
5956 auto-reconnect with another router as well. Affected file
5959 * Removed the [<key len>] option from CMODE command as the cipher
5960 name decides the key length, nowadays. See the defined ciphers
5961 from the protocol specification.
5963 * Added [<hmac>] option to the CMODE command to define the HMAC
5964 for the channel. Added SILC_CMODE_HMAC channel mode.
5966 * Added [<hmac>] option for the JOIN command so that user can
5967 select which HMAC is used to compute the MACs of the channel
5970 * Added Hmac field to the Channel Message Payload. The integrity
5971 of plaintext channel messages are now protected by computing
5972 MAC of the message and attaching the MAC to the payload. The
5973 MAC is encrypted. Now, it is clear that this causes some
5974 overhead to the size of the packet but rationale for this is that
5975 now the receiver can verify whether the channel message decrypted
5976 correctly and also when private keys are set for the channel the
5977 receiver can decrypt the packet with several keys and check from
5978 the MAC which key decrypted the message correctly.
5980 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5981 lib/silccrypt/silccipher.[ch].
5983 * Added silc_hash_len to return the digest length into the
5984 lib/silcrypt/silchash.[ch].
5986 * Rewrote parts of Silc Channel Payload interface in the
5987 lib/silccore/silcchannel.[ch]. The encode function now also
5988 encrypts the packet and parse function decrypts it.
5990 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Fixed a minor formatting bug in the SKE's key material processing.
5993 It actually might have processed the keys wrong way resulting
5996 * Redefined the mandatory HMAC algorithms and added new algorithms.
5997 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5998 and hmac-md5 truncated to 96 bits. The mandatory is now
5999 hmac-sha1-96. Rest are optional (including the one that used
6000 to be mandatory). Rationale for this is that the truncated HMAC
6001 length is sufficient from security point of view and can actually
6002 make the attack against the HMAC harder. Also, the truncated
6003 HMAC causes less overhead to the packets. See the RFC2104 for
6006 * Added new [hmac] configuration section. The SKE used to use
6007 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6008 is of course wrong. The official names that must be proposed in
6009 the SKE are the ones defined in the protocol specification
6010 (hmac-sha1-96 for example). The user can configure any hmac
6011 using any hash function configured in the [hash] section. At
6012 least, the mandatory must be configured.
6014 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6016 * Added HMAC list to the SKE proposal list. It has now both
6017 hash algorithm list and HMAC list. This makes the protocol
6018 incompatible with previous versions. The SKE now seems to work
6019 the way it is supposed to work, for the first time actually.
6021 * Defined plain Hash algorithms to the protocol specification.
6024 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Implemented support for key agreement packets into the server.
6027 Added functions silc_server_key_agreement and
6028 silc_server_send_key_agreement. Other than these functions,
6029 server has nothing to do with this packet.
6031 * Added support for private message key packets into the server.
6032 Added functions silc_server_private_message_key and
6033 silc_server_send_private_message_key.
6037 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6038 called in the protocol's final callback instead in the END
6039 protocol state. This makes a little more sense and in the same
6040 time in client we can use the same protocol routines for normal
6041 key exchange and to key agreement packet handling as well.
6043 * Added to both client's and server's KE protocol context the
6044 SilcSKEKeyMaterial pointer to save the key material. We will
6045 bring the key material to the protocol's final callback by doing
6046 this. The final callback must free the key material.
6048 * Added SKE's packet_send callback into client's KE protocol
6049 context so that the caller can choose what packet sending function
6050 is used. This way we can use different packet sending when
6051 doing normal SKE when doing key agreement packet handling (in
6052 the key agreement packet handling we do not want to encrypt
6055 * Implemented the responder side of the key agreement routines
6056 in the client. The client can now bind to specified port and
6057 accept incoming key negotiation. The key material is passed
6058 to the application after the protocol is over.
6060 * Implemented the processing of incoming Key Agreement packet
6061 in the client. Added function silc_client_key_agreement to
6064 * Implemented the intiator side of the key agreement routines
6065 in the client. The client can now initiate key agreement with
6066 another remote client. The key material is passed to the
6067 application after the protocol is over.
6069 * Created client_keyagr.c to include all the key agreement
6072 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6073 SILC_TASK_CALLBACK except that it is not static.
6075 * Created client_notify.c and moved the Notify packet handling
6076 from the client.[ch] into that file.
6078 * Created client_prvmsg.c and moved all private message and
6079 private message key routines from the client.[ch] into that file.
6081 * Create client_channel.c and moved all channel message and
6082 channel private key routines from the client.[ch] into that file.
6084 * Changed silc_client_get_client_by_id_resolve to resolve with
6085 WHOIS command instead of IDENTIFY command, in the file
6086 lib/silclient/idlist.c.
6088 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Implemented the SKE's responder side to the Client library.
6092 * When FAILURE is received to the protocol do not trust it
6093 blindly. Register a timeout to wait whether the remote closes
6094 the connection as it should do it, only after that process the
6095 actual failure. This was changed to both client and server.
6097 * Added client_internal.h to include some of the structures
6098 there instead of client.h in lib/silcclient/.
6100 * Added function silc_task_unregister_by_callback to unregister
6101 timeouts by the callback function.
6103 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Some "Incomplete WHOIS info" errors has been appearing on the
6106 log files. Took away the entry->userinfo check from WHOIS
6107 reply sending. The entry->userinfo is now " " if client did not
6108 provide one. I thought this was fixed earlier but something
6109 is wrong still. Let's see if the error still appears.
6111 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Fixed a minor bug in the login when the channel key is
6114 re-generated in the server. It used to generate the key in
6115 wrong order and thus caused problems in the channel traffic.
6117 * Fixed a minor bug in channel key distsribution after
6118 KICK command. The key was not sent to the router even though
6121 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Added silc_ske_process_key_material_data as generic routine
6124 to process any key material as the SILC protocol dictates. The
6125 function is used by the actual SKE library but can be used by
6126 applications as well. This relates to the private message keys
6127 and the channel private keys since they must be processed the
6128 same way the normal SILC session keys. The protocol dictates
6129 this. Affected files: lib/silcske/silcske.[ch].
6131 Added also silc_ske_free_key_material to free the
6132 SilcSKEKeyMaterial structure.
6134 * Defined silc_cipher_set_key function to set the key for
6135 cipher without using the object's method function. The affected
6136 files: lib/silccrypt/silccipher.[ch].
6138 * Implemented silc silc_client_add_private_message_key,
6139 silc_client_add_private_message_key_ske,
6140 silc_client_del_private_message_key,
6141 silc_client_list_private_message_keys and
6142 silc_client_free_private_message_keys functions in the
6145 Added functions silc_client_send_private_message_key to send
6146 the Private Message Key payload and silc_client_private_message_key
6147 to handle incoming Private Message Key payload.
6149 * Added Cipher field to the Private Message Key payload to set
6150 the cipher to be used. If ignored, the default cipher defined
6151 in the SILC protocol (aes-256-cbc) is used.
6153 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Removed lib/silcclient/ops.h file.
6157 Redefined parts of the SILC Client Library API. Created new
6158 file silcapi.h that deprecates the ops.h file and defines the
6159 published Client Library API. Defined also private message key
6160 API and channel private key API into the file.
6162 This is the file that the application must include from the
6163 SILC Client Library. Other files need not be included by
6164 the application anymore.
6166 * Added new key_agreement client operation callback and also
6167 defined the Key Agreement library API for the application.
6169 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6171 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6172 is used by clients to request key negotiation between another
6173 client in the SILC network. If the negotiation is started it
6174 is performed using the SKE protocol. The result of the
6175 negotiation, the secret key material, can be used for example
6176 as private message key.
6178 Implemented the Key Agreement payload into the files
6179 lib/silccore/silauth.[ch].
6181 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Redefined ciphers for the SILC protocol. Added some new ciphers
6184 and defined the key lengths for the algorithms. Changed the
6185 code accordingly. The default key length is now 256 bits.
6187 * Fixed SKE key distribution function silc_ske_process_key_material
6188 when the key length is more than 128 bits. The default key
6189 length in SILC is now 256 bits.
6191 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6192 to indicate unsupported algorithm.
6194 * Renamed rijndael.c to aes.c and all functions as well.
6196 * Fixed a long standing channel key setting bug in client library.
6197 Weird that it has never surfaced before.
6199 * Fixed bug in channel deletion. If the entire channel is removed
6200 then it must also delete the references of the channel entry
6201 from the client's channel list as the client's channel entry and
6202 the channel's client entry share same memory.
6204 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Implemented CONNECT and SHUTDOWN commands in the client.
6208 * Implemented CLOSE command to the client.
6210 * Added the function silc_idlist_find_server_by_name into the
6211 files silcd/idlist.[ch].
6213 Added the function silc_idlist_find_server_by_conn into the
6214 files silcd/idlist.[ch].
6216 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * DIE command was renamed to SHUTDOWN. Updated the both code
6221 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6222 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6224 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6227 * Added function silc_server_create_connection function to create
6228 connection to remote router. My server implementation actually
6229 does not allow router to connect to normal server (it expects
6230 that normal server always initiates the connection to the router)
6231 so the CONNECT command is only good for connecting to another
6234 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6237 or some other client was kicked from the channel.
6239 Implemented the handling of the notify type to both client
6242 Implemented silc_server_send_notify_kicked to send the KICKED
6243 notify. It is used to send it to the server's primary router.
6245 * Implemented the KICK command into server and client.
6247 * Added `query' argument to the silc_idlist_get_client function
6248 to indicate whether to query the client from server or not if
6251 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6252 to indicate that the client is not channel founder.
6256 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Removed the rng context from SilcPacketContext structure and
6259 changed that the packet routine uses the Global RNG API.
6261 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Added support for quit message that client can "leave" on the
6264 channel when it quits the SILC. It is ditributed inside the
6265 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6267 Added silc_server_free_client_data that will take the
6268 signoff message as argument.
6270 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6272 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Updated parts of the protocol specification to keep it up
6277 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6280 payloads in one packet.
6282 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6283 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6284 use now the new List flag.
6286 * Also deprecated the following packet types: REPLACE_ID,
6287 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6289 * Added list support for Notify packet in server.
6291 * Added silc_server_send_notify_channel_change to send the
6292 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6293 the silc_server_send_replace_id.
6295 * Added silc_server_send_notify_nick_change to send the
6296 NICK_CHANGE notify type. Deprecates the function
6297 silc_server_send_replace_id.
6299 * Added silc_server_send_notify_join to send the JOIN notify type.
6300 Deprecates the function silc_server_send_new_channel_user.
6302 * Added silc_server_send_notify_leave to send LEAVE notify type.
6303 Deprecates the function silc_server_send_remove_channel_user.
6305 * Added silc_server_send_notify_cmode and
6306 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6307 types. Deprecates the silc_server_send_set_mode function.
6309 * Added SERVER_SIGNOFF notify type to indicate that server has
6310 quit. This means that all clients on the channel from that
6311 server will drop. This can be also used when netsplit happens.
6313 Deprecated REMOVE_ID packet type since it is not needed anymore
6316 Added silc_server_send_notify_server_signoff to send the
6317 SERVER_SIGNOFF notify type. Deprecates the function
6318 silc_server_send_remove_id.
6320 Added also silc_server_send_notify_signoff to send the
6321 SIGNOFF notify type.
6323 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6324 SILC protocol from this day on. Changed the protocol
6325 specification as well.
6327 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6328 notify type. It is used between routers to notify about
6329 topic changes on a channel.
6331 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6334 * Partly updated the protocol specification to comply with the
6335 changes now made. It is still though a bit outdated.
6337 * The JOIN notify type now takes one extra argument <Channel ID>.
6338 The packet used to be destined to the channel but now the
6339 JOIN type may be sent as list thus it is impossible to
6340 destine it to any specific channel. By adding this argument
6341 it is again possible.
6343 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Added CREDITS file. The CHANGES and CREDITS file will appear
6346 in the distribution as well.
6348 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6351 types in the server's silcd/packet_receive.c.
6353 * Implemented CMODE and CUMODE to work in router environment.
6355 * Fixed minor encoding and decoding buglet from the
6356 lib/silccore/silcmode.c.
6358 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6361 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6363 * Changed all SilcConfigServer* and silc_config_server* to
6364 SilcServerConfig* and silc_server_config*, respectively.
6367 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Associated the ID (client or server ID) to the Authentication
6370 Payload to avoid any possibility of forging. Updated the
6371 protocol specification and the code accordingly.
6373 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * The RSA key length is now save to the RsaKey context in the
6376 key generation process in lib/silccrypt/rsa.c. The key length
6377 is now used to figure out the maximum size of the block allowed
6378 to be encrypted/signed.
6380 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6381 is equivalent to the silc_mp_mp2bin but does not allocate any
6384 * Changed silc_mp_mp2bin API to take length argument. If it is
6385 non-zero then the buffer is allocated that large. If zero, then
6386 the size is approximated using silc_mp_sizeinbase, which however
6389 * Created Global RNG API which is global RNG that application can
6390 initialize. After initializing, any routine anywhere in the
6391 code (including library) can use RNG without allocating a new
6392 RNG object. This was done to allow this sort of use of the
6393 RNG in code that has no chance to allocate RNG object. All
6394 applications currently allocate this and many routines in the
6395 library use this. Affected file lib/silccrypt/silcrng.[ch].
6397 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6398 it to use the Global RNG API.
6400 * Defined Authentication Payload into protocol specification that
6401 is used during SILC session to authenticate entities. It is
6402 used for example by client to authenticate itself to the server
6403 to obtain server operator privileges.
6405 Implemented this payload into the lib/silccore/silcauth.[ch].
6406 Implemented also routines for public key based authentication
6407 as the new protocol specification dictates.
6409 Moved definitions of different authentication methods from
6410 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6412 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6413 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6414 silc_pkcs_verify_with_hash functions into the file
6415 lib/silccrypt/silcpkcs.[ch].
6417 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * The client entry's userinfo pointer must be always valid.
6420 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6421 will fail since it requires the userinfo. Now, the userinfo
6422 is allocated as "" if actual userinfo does not exist. Actually,
6423 it must exist and it is totally Ok to drop client connections
6424 that does not announce the userinfo. However, we will make
6425 this workaround for now.
6427 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6428 to return the remote port by socket.
6430 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6433 SILC_SERVER_PENDING_EXEC and added an new macro
6434 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6435 data or when error occurs while processing the pending command.
6437 Added new argument `destructor' into silc_server_command_pending
6438 and to the SilcServerCommandPending object. This destructor is
6439 now called after calling the pending callback or if error occurs
6440 immediately. If error occurs the actual pending callback won't
6441 be called at all - only the destructor. The destructor may be
6442 NULL if destructor is not needed.
6444 All this applies for client library code as well. Similar
6445 changes were made there as well for the pending commands.
6447 In the client, the application must now allocate the
6448 SilcClientCommandContext with the silc_client_command_alloc
6451 * Added reference counter to the SilcServerCommandContext. Added
6452 function silc_server_command_alloc and silc_server_command_dup
6455 Same type of functions added to the client library for the same
6458 * Removed the cmd_ident from IDListData away since it is now
6459 global for all connections. It is the command identifier used
6460 in command sending and with pending commands. The affected file
6463 * Added reference counter to the SilcSocketConnection objecet to
6464 indicate the usage count of the object. The object won't be
6465 freed untill the reference counter hits zero. Currently only
6466 server uses this, and client ignores it. The client must be
6467 set to use this too later. The affected files are
6468 lib/silccore/silcsockconn.[ch]. Added also the function
6469 silc_socket_dup to increase the reference counter.
6471 This was mainly added because it is possible that the socket
6472 is removed underneath of pending command or other async
6473 operation. Now it won't be free'd and proper DISCONNECTING
6474 flags, etc. can be set to avoid sending data to connection that
6475 is not valid anymore.
6477 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6478 the connection. After that it sets SILC_SET_DISCONNECTED.
6479 It is, however, possible that the socket data is not still freed.
6480 The silc_server_packet_process now checks that data is not
6481 read or written to connection that is DISCONNECTED. The socket
6482 get's freed when the reference counter hits zero.
6484 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * Changed the client operation API: channel_message operation's
6487 `sender' is now the client entry of the sender, not the nickname
6488 and the `channel' is the channel entry, not the channel name.
6490 In the private_message operation the `sender' is now also the
6491 client entry of the sender not the nickname.
6493 Affected file is lib/silcclient/ops.h and all applications
6494 using the client operations.
6496 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Moved the calling of ops->connect() from connect_to_server_final
6499 into receive_new_id functin since that is the point when the
6500 client is actually allowed to send traffic to network. The
6501 affected file is lib/silcclient/client.c.
6503 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6506 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6507 (if needs broadcasting) instead of broadcasting the packets one
6508 by one which would make a burst in the network traffic.
6510 * Added `broadcast' argument to the functions in silcd/server.[ch]
6511 silc_server_create_new_channel[_with_id] to indicate whether
6512 to send New Channel packet to primary router.
6514 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * Added new function into the silcd/server.[ch] files:
6517 silc_server_create_new_channel_with_id to create new channel with
6518 already existing Channel ID.
6520 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6521 lib/silccore/silcpacket.h. This packet is used t send list of
6522 Set Mode payloads inside one packet. Server uses this to set
6523 the modes for the channels and clients on those channels, that it
6524 announced to the router when it connected to it. The protocol
6525 specification has been updated accordingly.
6527 * The silc_server_new_channel did not handle the packet coming
6528 from normal server as it normally does not send that. However,
6529 when it announces its channels it does send it. Implemented
6530 the support for that.
6532 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6533 into the file lib/silccore/id.h.
6535 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Fixed memory leaks in the functions silc_idlist_del_client,
6538 silc_idlist_del_channel and silc_idlist_del_server in the file
6539 silcd/idlist.c. All of those leaked like a sieve.
6541 * Fixed some small memory leaks in the client's function
6542 silc_client_notify_by_server.
6544 * Added functions into silcd/server.c: silc_server_announce_clients,
6545 silc_server_announce_channels and silc_server_announce_server.
6546 These functions are used by normal and router server to announce
6547 to its primary router about clients, channels and servers (when
6548 router) that we own. This is done after we've connected to the
6551 These functions effectively implements the following packet types:
6552 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6553 and SILC_PACKET_NEW_ID_LIST.
6555 * Added new functions into the silcd/packet_receive.[ch]:
6556 silc_server_new_id_list, silc_server_new_channel_list and
6557 silc_server_new_channel_user_list to handle the incoming
6558 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6560 * Added support of changing Channel ID in the function
6561 silc_server_replace_id. If the server that announces a channel
6562 to the router already exists in the router (with same name but
6563 with different Channel ID), router is responsible to send
6564 Replace ID packet to the server and force the server to change
6565 the Channel ID to the one router has.
6567 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6568 client that the Channel ID has been changed by the router. The
6569 normal server sends this to the client. Client must start using
6570 the new Channel ID as the channel's ID.
6572 Implemented handling of this new type into lib/silcclient/client.c
6573 into the function silc_client_notify_by_server.
6575 * Added new function silc_idlist_replace_channel_id into the files
6576 silcd/idlist.[ch] to replace the Channel ID.
6578 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Call silc_server_command_identify_check always when processing
6581 the IDENTIFY command in silcd/command.c
6583 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6586 send keepalive packets. The packet can be sent by clients,
6587 servers and routers.
6589 Added function silc_socket_set_heartbeat into the file
6590 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6591 If not set, the heartbeat is not performed. The actual
6592 heartbeat is implemented in the low level socket connection
6593 library. However, application is responsible of actually
6596 Added silc_server_send_heartbeat to send the actual heartbeat
6597 packet into silcd/packet_send.[ch]. Server now performs
6598 keepalive with all connections.
6600 * Added silc_task_get_first function into lib/silcutil/silctask.c
6601 to return the timeout task with shortest timeout. There was a bug
6602 in task unregistration that caused problems. TODO has been
6603 updated to include that task system must be rewritten.
6605 * The client library will now resolve the client information when
6606 receiving JOIN notify from server for client that we know but
6607 have incomplete information.
6609 * Rewrote parts of silc_server_remove_from_channels and
6610 silc_server_remove_from_one_channel as they did not remove the
6611 channel in some circumstances even though they should've.
6613 * Encryption problem encountered in server:
6615 The LEAVE command used to send the Channel Key packet to the
6616 router immediately after generating it. However, the code
6617 had earlier sent Remove Channel user packet but not immediately,
6618 ie. it was put to queue. The order of packets in the router
6619 was that Channel Key packet was first and Remove Channel User
6620 packet was second, even though they were encrypted in the
6621 reverse order. For this reason, MAC check failed. Now, this
6622 is fixed by not sending the Channel Key packet immediately but
6623 putting it to queue. However, this is more fundamental problem:
6624 packets that are in queue should actually not be encrypted
6625 because packets that are sent immediately gets encrypted
6626 actually with wrong IV (and thus MAC check fails). So, packets
6627 that are in queue should be encrypted when they are sent to
6628 the wire and not when they put to the queue.
6630 However, the problem is that the current system has not been
6631 designed to work that way. Instead, the packet is encrypted
6632 as soon as possible and left to the queue. The queue is then
6633 just purged into wire. There won't be any fixes for this
6634 any time soon. So, the current semantic for packet sending
6637 o If you send packet to remote host and do not force the send
6638 (the packet will be in queue) then all subsequent packets to the
6639 same remote host must also be put to the queue. Only after the
6640 queue has been purged is it safe again to force the packet
6643 o If you send all packets immediately then it safe to send
6644 any of subsequent packets through the queue, however, after
6645 the first packet is put to queue then any subsequent packets
6646 must also be put to the queue.
6648 Follow these rules and everything works fine.
6650 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Added new function silc_server_remove_clients_by_server to
6653 remove all client entries from ID list when the server connection
6654 is lost. In this case it is also important to invalidate all
6655 client entires as they hold the invalid server entry. This
6656 fixes fatal bug when server has lost connection and will reconnect
6659 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Made some sanity checks to silc_server_daemonise like to check
6662 whether the requested user and group actually exists.
6664 * Added sanity check to SKE's silc_ske_responder_finish to check
6665 that the public and private key actually is valid.
6667 * Invalidate the client's nickname when receiving Replace ID
6668 packet and the Client ID is being replaced. This means that the
6669 server will query the nickname if someone needs it (client)
6672 * Sort the ID Cache in client library when the ID Cache data
6673 has changed (needs sorting).
6675 * Do not allow for SILC client to create several connections to
6676 several servers. The client does not support windows right now
6677 and generating multiple connections causes weird behaviour.
6679 Irssi-silc client does support windows and can handle several
6680 connections without problems, see: www.irssi.org and SILC plugin.
6682 * Fixed some places where client was added to the IDList. The
6683 rule of thumb is following (in order to get everything right):
6684 If the client is directly connected local client then the
6685 `connection' argument must be set and `router' argument must be
6686 NULL to silc_idlist_add_client function. If the client is not
6687 directly connected client then the `router' argument must
6688 bet set and the `connection' argument must be NULL to the
6689 silc_idlist_add_client function.
6691 * The funtion silc_server_packet_send_local_channel actually did
6692 not check whether the client was locally connected or not. It
6693 does that now. Fixed a bug related to LEAVE command.
6695 * Fixed Remove Channel User payload parsing bug in server's
6696 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6698 * The server's silc_server_save_channel_key now checks also the
6699 global ID list for the channel as it might not be in the local
6700 list. Fixed a bug related to LEAVE command.
6702 * Is this the end of the [<unknown>] buglet that has been lurking
6703 around for a long time? A little for loop fix in server's
6704 silc_server_command_whois_parse that is used by both IDENTIFY
6705 and WHOIS command. At least, this was a clear bug and a cause
6706 of one type of [<unknown>] buglet.
6708 * WHOIS and IDENTIFY commands call the function
6709 silc_server_command_[whois/identify]_check function even if
6710 we are not router server.
6712 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added --with-gmp configuration option. If set the GMP
6715 is always compiled in the SILC source tree. If not set then
6716 it is checked whether the system has the GMP3 installed. If
6717 it has then the GMP won't be compiled (the system's headers
6718 and library is used), if it doesn't have it then the GMP is
6719 compiled in the SILC source tree.
6721 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Changed RSA private exponent generation to what PKCS #1
6724 suggests. We try to find the smallest possible d by doing
6725 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6726 not security fix but optimization.
6728 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Added new config entry [Identity] to fork the server and run
6731 it as specific user and group. A patch from Bostik.
6733 * Imported Dotconf configuration library into lib/dotconf.
6734 This will be used to create the SILC configuration files later.
6735 It will appear in the distsribution after this commit.
6737 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * A big code auditing weekend happening. Auditing code for
6740 obvious mistakes, bugs and errors. Also, removing any code
6743 Removed files for being obsolete:
6745 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6746 inline in the file lib/silcutil/silcbuffer.h)
6748 o lib/silcutil/silcbufutil.c (the header has inline versions)
6750 Changed code to fix possible error conditions:
6752 o The buffer formatting routines now check that the destination
6753 buffer really has enough space to add the data. This applies for
6754 both buffer formatting and unformatting
6755 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6756 unformatting was changed to accomodate following rules:
6757 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6758 sent to the function while XXX_*STRING will not allocate or copy
6759 the data into the buffer. Instead it sets the pointer from the
6760 buffer into the pointer sent as argument (XXX_*STRING used to
6761 require that the pointer must be allocated already). This change
6762 makes this whole thing a bit more consistent and more optimized
6763 (note that the data returned in the unformatting with XXX_*STRING
6764 must not be freed now). The routines return now -1 on error.
6766 o Tried to find all code that use buffer_format and buffer_unformat
6767 and added return value checking to prevent formatting and
6768 especially unformatting errors and possible subsequent fatal
6771 o Changed ske->x and ske->KEY to mallocated pointers in
6772 lib/silcske/silcske.h. Fixed possible data and memory leak.
6774 o Added return value checking to all *_parse* functions. Fixed
6775 many memory leaks as well.
6777 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6778 so that buffer overflows would not happen. All code now also
6779 checks the return value as it can fail.
6781 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * Added reconnection support to server if the normal server looses
6784 its connection to the router (for example if router is rebooted).
6785 The server performs normal reconnection strategy implemented
6786 to the server. Affected file silcd/server.c.
6788 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6790 * Added new packet type SILC_PACKET_SET_MODE that is used to
6791 distribute the information about changed modes (for clients,
6792 channels and clients channel modes) to all routers in the
6793 network. Updated the protocol specification accordingly.
6795 Added functions into silcd/packet_send.c and
6796 silcd/packet_receive.c: silc_server_send_set_mode,
6797 silc_server_set_mode.
6799 Added new files silcmode.[ch] into lib/silccore that implements
6800 the encoding and decoding of Set Mode Payload. Added new type
6801 SilcSetModePayload. Moved the definitions of different modes
6802 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6804 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Oops, a little mistake in server's connection authentication
6807 protocol. The protocol is not ended with FAILURE but with
6808 SUCCESS if the authentication is Ok. :) Affected file is
6811 * Implemented NICK_CHANGE notify handling in server in the file
6812 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6813 the local clients on the channel. After the changing nickname
6814 in router environment snhould work and the [<unknown>] nickname
6815 should appear no more.
6817 The silc_server_replace_id function that receives the Replace ID
6818 payload now sends the NICK_CHANGE notify type also in the file
6819 silcd/packet_receive.c
6821 * Changed WHOIS and IDENTIFY command to support the maximum amount
6822 of arguments defined in protocol specs (3328 arguments). This
6823 fixed a bug that caused problems when there were more than three
6826 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added extra parameter, command identifier, to the
6829 silc_client_send_command so that explicit command identifier
6832 Changed that ID list routines uses specific command identifier
6833 when sending WHOIS/IDENTIFY requests to the server so that they
6834 can be identified when the reply comes back.
6836 Affected files lib/silcclient/command.[ch],
6837 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6839 * Added `sender' argument to silc_server_packet_send_to_channel
6840 to indicaet the sender who originally sent the packet to us
6841 that we are now re-sending. Ignored if NULL. Affected file
6842 silcd/packet_send.[ch].
6844 * Added some server statistics support in silcd/server_internal.h
6845 SilcServerStatistics structure and around the server code. Also
6846 send some nice statistics information when client is connecting
6849 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6851 * Fixed channel ID decoding in server's JOIN command reply in
6852 silcd/command_reply.c
6854 * Fixed braodcasting of replace ID payload to not to send it if
6855 we are standalone server in silcd/packet_receive.c.
6857 * Fixed all channel message sending routines to not to send
6858 packets to clients that has router set, since they are routed
6859 separately in the same function earlier. Affects file
6860 silcd/packet_send.c and all channel packet sending functions.
6862 * In USERS reply, res_argv[i] are not allocated, the table
6863 is allocated. Thus changed that free the table, not its
6866 * In server's whois_check and identify_check if the client is
6867 locally connected do not send any WHOIS commands - they are not
6870 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6872 * Fixed some minor bugs in client when sending WHOIS command. The
6873 arguments was in wrong order.
6875 * Removed statis function add_to_channel from server in
6876 silcd/command.c that was previously used with the joining but
6879 * Tested USERS command in router environment successfully with two
6880 routers, two servers and two clients.
6882 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6884 * Reorganized the USERS command and command reply in client library
6885 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6886 When the command is given by user we register a pending command
6887 callback that will reprocess the command after the reply has been
6888 received from the server. When reprocessing the packet we then
6889 display the information. Thus, the USERS information is displayed
6890 now in the command callback instead of in the command reply
6891 callback. The processing of the command is same as previously
6892 when server has sent the command reply in the JOINing process.
6894 * Added to USERS command in silcd/command_reply.c to join the client,
6895 we didn't use to know about, to the channel after we've created
6896 a client entry for it. Also, for clienet we did know already still
6897 check whether it is on the channel or not and add it if not.
6899 * Removed silc_server_command_join_notify as the function and its
6902 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * Changed the client's pending command handling to the same as the
6905 server's pending command handling. It is also now possible to
6906 execute command reply functions from other command reply
6907 function as the function callbacks for commands and command
6908 replies are one and same. The pending commands are not static
6909 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6910 in client connection context. Thus, pending commands are server
6911 connection specific as it is convenient.
6913 Changed the function silc_client_command_pending and
6914 silc_client_command_pending_del and added new function
6915 silc_client_command_pending_check. Removed the
6916 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6919 * Added cmd_ident, current command identifier, to the client
6920 connection context in lib/silcclient/client.h to keep track on
6921 command identifiers used in command sending. Client's command reply
6922 function handling now supports the mandatory command identifiers.
6924 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6925 funtions in client to fully support pending command callbacks.
6927 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6928 as one of the arguments to the application in the command reply
6931 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6932 before first releasing SILC but came back. Now it is removed again
6933 and should come back nomore. The FORWARDED flag was used only
6934 by the JOINing procedure by forwarding the command packet to router.
6935 Now, the JOINing procedure has been changed to more generic (due
6936 to various router environment issues) and FORWARDED is not needed
6937 anymore for anything. The protocol specification is yet to be
6940 Now, removed silc_server_packet_forward from server and the flag
6941 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6943 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Renamed NAMES command to USERS command. The NAMES was named that
6946 due to historical reasons. Now it is renamed. Also, rewrote
6947 parts of the USERS command. The nickname list is not sent anymore
6948 by the server. Only Client ID and mode lists are sent in the USERS
6949 command. Changed this also to the protocol specification.
6951 The client now resolves the names and stuff after it receives
6952 the USERS list from the server when joining to the channel.
6954 * WHOIS and IDENTIFY commands has been changed to support multiple
6955 Client ID's per command. One can now search for multiple users
6956 in the network by sending only one WHOIS or IDENTIFY command.
6957 Changed the code and the protocol specifications.
6959 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6960 uses silc_server_command_whois_parse to parse the request. */
6962 * If normal server, do not parse the WHOIS and IDENTIFY requests
6963 before sending it to the router. Saves some time.
6965 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Fixed JOIN command on client library. Wrong number of arguments
6968 used to crash the client.
6970 * Added silc_server_channel_has_global function to check whether
6971 channel has global users or not.
6973 * Added silc_server_channel_has_local function to check whether channel
6974 has locally connected clients on the channel.
6976 * The silc_server_remove_from_one_channel now checks whether the
6977 channel has global users or not after given client was removed from
6978 the channel. It also checks whether the channel has local clients
6979 on the channel anymore. If it does not have then the channel entry
6980 is removed as it is not needed anymore.
6982 * The silc_server_notify now checks on JOIN notify whether the joining
6983 client is one of locally connected or global. If it is global then
6984 the channel has now global users on the channel and that is marked
6985 to the channel entry. Also, it now saves the global client to
6986 global list who is joining and JOINs it to the channel. This is
6987 for normal server, that is.
6989 Changed silc_server_send_notify_on_channel,
6990 silc_server_packet_relay_to_channel and
6991 silc_server_packet_send_to_channel check if we are normal server
6992 and client has router set (ie. global client) do not send the
6993 message to that client, as it is already routed to our router.
6995 * Implemented LEAVE notify type handling in silc_server_notify
6998 * Tested LEAVE command in router environment successfully. Tested
6999 with two routers, two servers and two clients.
7003 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7005 * Implemented SIGNOFF notify type handling in silc_server_notify
7008 * silc_server_remove_id now removes the client entry from all channels
7009 it has joined and thusly sends SIGNOFF notify type.
7011 * Rewrote the NAMES list generation in server by removing two excess
7012 loops. The lists are created now inside one loop.
7014 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * silc_server_remove_channel_user checks now also global list
7017 for channel and client.
7019 * silc_server_new_channel_user checks now both local and global
7020 list for channel and client. Fixed a bug in client id decoding.
7021 Used to decode wrong buffer.
7023 * silc_server_channel_message checks now both local and global
7024 list for channel entry.
7026 * Tested channel joining (hence JOIN) in router environment
7027 successfully. Tested with two routers, two servers and two
7030 * Tested channel message sending in router environment successfully.
7032 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7034 * Added silc_server_save_channel_key into server.[ch] to save the
7035 received channel key in Channel Key payload processing. It is
7036 also used in JOIN command reply handling.
7038 Equivalent function silc_client_save_channel_key added into
7039 client.[ch] into client library.
7041 * Changed JOIN command reply to send information whether the channel
7042 was created or not (is existing already) and the channel key
7043 payload. Changed protocol specs accordingly.
7045 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7046 the request was sent by ID and not by nickname. Crashed on
7049 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7052 now correctly save the received data.
7054 * silc_server_free_sock_user_data now notifies routers in the
7055 network about entities leaving the network.
7057 At the same time implemented functions silc_server_remove_id
7058 and silc_server_send_remove_id to receive and send REMOVE_ID
7059 packets. The packet is used to notify routers in the network
7060 about leaving entities. The ID removed will become invalid in
7063 * Added function silc_idlist_del_server into server. Removes and
7064 free's server entry from ID list.
7066 * silc_server_private_message function now checks, if we are router,
7067 that the destination ID really is valid ID, naturally.
7069 * In router when NEW_ID packet is received (for new client) the
7070 hash of the Client ID is saved in the ID Cache but the
7071 client->nickname is set to NULL, instead of putting the hash
7074 IDENTIFY command now also checks that client->nickname must be
7075 valid. If it is not if will request the data from the server who
7076 owns the client. Added new function
7077 silc_server_command_identify_check.
7079 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7080 to set the command to already allocated Command Payload.
7082 * Tested private message sending in router environment with two
7083 routers, two servers and two clients. Fixed minor bugs and now
7086 * Fixed segfault from client's NAMES command. Used to crash if
7089 * Forwarded packets must not be routed even if it is not destined
7090 to the receiver. Changed server code comply with this.
7092 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Added `require_reverse_mapping' boolean value to ServerParams
7095 structure. If TRUE (not default) the server will require that
7096 the connecting host has fully qualified domain name.
7098 If the reverse mapping is not required and hostname could not be
7099 found the IP address is used as hostname.
7101 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Implemented version string checking to both client and server.
7104 The check is incomplete currently due to the abnormal version
7105 strings used in development version of SILC.
7107 * Changed all command functions in server to use the new
7110 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Changed char *data to unsigned char *data in ID Cache system to
7113 support binary data as ID Cache data. Changed code to support
7114 binary data in lib/silccore/idcache.c.
7116 * Renamed silc_server_packet_relay_command_reply to
7117 silc_server_command_reply as it is normal packet receiving
7118 function. Rewrote the function to accept command replys for
7119 servers and not only for clients.
7121 * Mark remote router always as registered server if we are connecting
7122 to it. Otherwise, commands sent by the router to us are ignored.
7124 * All ID List find routines now returns the ID Cache Entry pointer
7125 as well if requested.
7127 * WHOIS command works now in router environment, tested with two
7128 routers, two servers and two clients.
7130 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7131 in router environment (as it is almost equivalent to WHOIS) but
7132 hasn't been tested thoroughly. Added new functions:
7134 silc_server_command_identify_parse
7135 silc_server_command_identify_send_reply
7136 silc_server_command_identify_from_client
7137 silc_server_command_identify_from_server
7139 * Disabled route cache adding because adding two different ID's with
7140 same IP replaces the old cache entry thus giving wrong route.
7141 The entry->router->connection is always the fastest route anyway
7142 so route cache may not be needed. Of course, new routes maybe
7143 established after receiving the ID when the entry->router->connection
7144 might not be anymore the most optimal.
7146 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Add route cache for received ID for fast routing.
7150 * Added silc_server_packet_route to route received packet on router
7151 that is not destined to us.
7153 * Renamed silc_server_get_route to silc_server_route_get.
7155 * Added id_string and id_string_len fields into SilcServer to
7156 include encoded ServerID for fast comparing without excess
7157 encoding of the ID's.
7159 * Cleaned up WHOIS command on server side. Added following static
7162 silc_server_command_whois_parse
7163 silc_server_command_whois_check
7164 silc_server_command_whois_send_reply
7165 silc_server_command_whois_from_client
7166 silc_server_command_whois_from_server
7168 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7169 arguments in command replies. All command functions should be
7170 updated to use this macro.
7172 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7174 * Minor typo fixes on command reply handling on server.
7176 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added silc_server_command_add_to_channel internal routine to add
7179 the client to the channel after router has created the channel and
7180 sent command reply to the server.
7182 * Added generic silc_server_send_command to send any command from
7185 * Use static buffer with ID rendering instead of duplicating data.
7187 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Fixed a channel user mode bug when joining to a channel server gave
7190 everybody channel founder rights, oops.
7192 * We mark ourselves as the router of the incoming server connection
7193 if we are router ourselves. This way we can check in some packet
7194 sending functions whether it is locally connected server. For
7195 incoming router connections we put NULL.
7197 * For router sending packets locally means now always sending the
7198 packet cell wide; to local clients and local servers. For normal
7199 server sending packet locally means sending it to only local
7202 * Fixed the JOIN command to really work in router environment. If the
7203 channel is created it is always created by the router. Router is
7204 also responsible of making the initial joining to the channel,
7205 sending JOIN notify to the sending server and distributing
7206 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7207 does not exist server doesn't do anything else but forward the
7208 command to the router which performs everything.
7210 * Added silc_server_send_channel_key function to send the Channel Key
7213 * Added silc_server_create_channel_key to create new channel key. The
7214 channel key is now re-generated everytime someone joins or leaves
7215 a channel, as protocol dictates. Note: channel->key_len is the
7218 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7221 packet_receive.[ch] to separate packet sending and receiving
7222 routines. The server.[ch] now includes everything else including
7223 actual packet processing (writing and reading data) and other
7226 Renamed silc_server_private_message_send_internal to
7227 silc_server_send_private_message. The routine is still though
7228 used only to relay private messages as server does not send
7229 private messages itself.
7231 Renamed silc_server_new_channel to silc_server_create_new_channel
7232 and added new function sicl_server_new_channel that handles the
7233 incoming New Channel packet. Added also new sending function
7234 silc_server_send_new_channel to send New Channel Payload.
7236 * Added new function silc_server_notify to process incoming notify
7237 packet to the server/router. Server may then relay the notify
7238 to clients if needed.
7240 * Added new function silc_server_new_channel_user to process incoming
7241 New Channel User packet. Router will redistribute the packet and
7242 send JOIN notify to its local clients and locally connected servers
7243 if needed. Normal server will send JOIN notify to its local client
7244 on same channel when received this packet. Added also corresponding
7245 sending function silc_server_send_new_channel_user to sent the
7248 * Added boolean route argument to send_notif_to_channel and
7249 packet_send_to_channel functions to attempt to route the packet
7250 if it is TRUE and send only locally if it is FALSE.
7252 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * silc_server_replace_id now broadcasts the received replace ID
7255 packet if it is not broadcast packet already. The router must
7256 broadcast to inform other routers about changed ID.
7258 * Added backpointer to server's router into SilcServer context in
7259 silcd/server_internal.h.
7261 * Fixed silc_server_packet_broadcast to send correct broadcast
7264 * The channel key is now distributed to the local client as soon
7265 as it is received from the router (in router environment) so that
7266 no other packet may be sent for the channel until client has
7269 * silc_server_remove_channel_user now broadcasts the received
7270 Remove Channel User packet if it is not broadcast packet already.
7271 The router must broadcast to inform other routers about removed
7274 * Added users field into SilcPacketContext that is a reference count
7275 of the context. One can increase the reference count by calling
7276 silc_packet_context_dup which is now changed to just increase the
7277 reference count instead of duplicating the data. The reference
7278 count is decresed by calling silc_packet_context_free that will
7279 free the data after the reference count hits zero.
7281 For now on the packet context and everything allocated into it
7282 (including the raw packet from network) must be freed by calling
7283 the new silc_packet_context_free function. Added also new function
7284 silc_packet_context_alloc that must be used now to allocate the
7285 context. This also means that if a routine is asynchronous from
7286 silc_[client/server]_packet_parse_type the packet context must
7287 be duplicated by calling silc_packet_context_dup. Otherwise it
7288 gets free'd after silc_[client/server]_packet_parse_type returns.
7289 Also, one must remember that if packet is duplicated then its
7290 reference count must be decresed by calling the free function as
7291 many times as it was duplicated.
7293 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7294 from both client and server.
7296 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Made joining to a channel working in router environment.
7300 * Cleaned up JOIN command on server side and create function
7301 silc_server_command_join_channel internal routine to make the
7304 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7306 * Changed silc_command_pending list to SilcDList. Also, added
7307 `ident' field to SilcServerCommandPending structure to identify
7308 the reply and to call correct callback.
7310 Added silc_server_command_pending_check function to replace the
7311 corresnponding macro. The silc_command_pending list is not
7314 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7315 to set identifier to previously allocated Command Payload. It
7316 is used to set identifier for command when resending Command
7319 * Added silc_command_payload_encode_payload to encode Command
7320 Payload buffer from SilcCommandPayload structure.
7322 * Added silc_argument_payload_encode_payload to encode Argument
7323 payload buffer from SilcArgumentPayload structure.
7325 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Changed WHOIS command to support router connection on server side.
7328 The whois request is always sent to router unless the server is
7329 standalone server. After server has received the reply from the
7330 router will it send the reply to the client.
7332 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7333 broadcast received broadcast packet. The function is used only
7334 by router. The broadcast packet is always sent to the router's
7337 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7338 render given ID to printable string, for log files for example.
7340 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Made basic router to router connections working. At least they
7343 can now connect to each other but nothing really works the way
7344 they are supposed - yet.
7346 * Added new initiator token to RouterConnection configuration
7347 file in silcd/serverconfig.[ch]. It is used to tell whether we
7348 are the initiator to the remote router or whether we'll expect
7349 the other end to connect.
7351 * Moved registering of listener task to silc_server_init, hence
7352 the server starts listenning as soon as it is run, even if it
7353 does not have connections to other routers. Let's see how well
7356 * Changed default connection retry timeouts for more suitable in
7359 * Removed cipher and such arguments from silc_idlist_add_client
7360 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7361 Added new function silc_idlist_add_data to add the keys and stuff
7364 * Added SilcIDListData structure and added it to SilcClientEntry
7365 and SilcServerEntry as their first field in the structure. This
7366 way we can explicitly cast the ID entries to the SilcIDListData
7367 structure and get common data for the entries. In past, we had
7368 to first check what type of connection it is and then cast it to
7369 correct ID entry type. Now, we can directly cast the opaque
7370 pointer to the SilcIDListData (no matter what ID entry it actually
7371 is) and get the data needed.
7373 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7376 in some circumstances even if threre were timeout tasks, though not
7377 IO tasks, but tasks anyway. Now fixed.
7379 * Defined SilcServerConnection structure to hold connection specific
7380 stuff about directly connected servers and routers. The definition
7381 is currently in silcd/server_internal.h. I thought about having
7382 a bit more important role fro this struct but for now it is used
7383 only when connecting to other server (or router actually).
7385 * Added connecting retry support in server when connecting to
7386 router(s). The retry feature implement exponential backoff
7387 algorithm. Also, added SilcServerParams structure to hold default
7388 parameters for server. For now, it include these retry settings
7389 and are hard coded. After server is moded to be as Silc Server
7390 Library this structure will be more important.
7392 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7394 * Changed client librarys channel->clients table to SilcList and
7395 changed code accordingly.
7397 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Changed client's channel table to SilcList and changed code
7400 accordingly. Also changed SilcChannelClientEntry to include back-
7401 pointer to the channel so that client entry can use that structure
7402 as list as well and we have fast cross-reference to the channel.
7403 This change dramatically decreased the complexity of channel
7404 handling with client entry and vice versa (removed one extra
7405 loop when searching for channel entry from many functions).
7407 * Changed server->sim from table to SilcDList and changed code
7410 * NAMES command can now be used from user interface. It will show
7411 the user list on the channel, neatly.
7413 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7414 Code now saves realname of the user if it becomes available.
7416 * Renamed configure.in to configure.in.pre and made ./prepare
7417 script to automatically add correct version string to
7418 configure.in which it creates from configure.in.pre.
7420 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * NAMES command reply now shows users mode with the nickname when
7425 * Moved silc_client_ch[u]mode[_char] functions from
7426 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7427 place sucks, they are utility functions and should be in some
7430 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7432 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7435 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Added TRQ (efficient deque and list library) into lib/trq. This is
7440 a very good list library that is currently used in the SILC. Defined
7441 SilcList API over the library because I didn't like the API very
7442 much. See lib/trq/silclist.h for the API and examples of how to
7443 use the API. Fixed various places in the code to use the new
7444 SilcList API. The SilcList is meant for lists that has a structure
7445 already defined as a list. It is not suitable to add just some
7446 context to the list (in TRQ, the context is the list actually).
7448 So, I defined SilcDList that can be used for the purpose where
7449 predefined list structure does not exit. This can be used as
7450 such list. Now some context just can be added to the SilcDList.
7451 Currently this list is not used in the SILC just yet, though there
7452 are a lot places where this can replace dynamically allocated
7453 tables and I will fix these places, later, to use SilcDList.
7454 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7455 and use TRQ internally).
7457 Also fixed some annoying warning messages that the original TRQ
7458 code generated. Also minor changes to TRQ's Makefile.in.
7460 * Added support for querying by Client ID to both WHOIS and
7461 IDENTIFY commands into server, as required by the protocol.
7463 * Removed method function pointers from SilcBuffer structure. They
7464 weren't used to anything and just increased the context size for
7465 no good reason. This change also made silc_buffer_alloc and
7466 silc_buffer_free functions inline functions.
7468 * Disabled command flooding detection support until it's fixed so
7469 that it accepts commands in but does not execute them more than once
7472 * Added silc_net_localhost(), to return local hostname, into
7473 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7474 that must be initialized before calling silc_client_init.
7476 * Added new function: silc_server_send_notify_on_channels to send
7477 notify messages to all channels client has joined. It is assured
7478 that the message is sent only once per client.
7480 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7481 lib/silcutil/silcutil.[ch] as silc_format function. The new
7482 function is generic and is used by server as well, not only by
7483 the logging routines.
7485 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7486 the provided version string was not acceptable. Added new function:
7487 silc_ske_check_version into lib/silcske/silcske.h. The function
7488 must be implemented by the application (client or server) and it
7489 does not reside in the SKE library. The function checks the version
7490 string remote end sent.
7492 * Added back pointers (to opaque context and to SilcSocketConnection)
7493 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7495 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7496 duplicate packet context structure.
7498 * Changed `notify' client operation to send same arguments as client
7499 receives from server except for ID's. ID's are mapped to correct
7500 ID entry and that is returned. Also, if channel entry is not sent
7501 by server but the notify is for channel the channel entry is sent
7502 to application (otherwise application doesn't know that it is for
7503 channel (library gets it from packet's Destination ID)).
7505 * Added silc_client_remove_from_channels into client library to
7506 remove a client from all channels it has joined to. Used when
7507 received SIGNOFF notify from server. Added also new function
7508 silc_client_replace_from_channels to replace old ID entry with
7509 new ID entry on all channels. Used when received NICK_CHANGE
7512 * Fixed ID Cache list handling in silc_idlist_get_client in
7513 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7514 to get (or query) client by ID.
7516 * Updated TODO list.
7518 * Added connection authentication status message defined by the
7519 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7520 support for these into the code in client and server side.
7522 * Added generic function silc_client_send_command to send any command
7523 with variable argument list. Application should use this function
7524 to send commands if the command functions provided by the library
7525 does not suite for the application's user interface needs.
7527 * Added new `failure' client operation. Application is notified about
7528 received failure packet if client is executing a protocol. In this
7529 case the protocol's execution has failed.
7531 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7532 is required by the protocol.
7534 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7535 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7538 * Added status flag to SilcSKE object to indicate realtime status
7539 of the SKE protocol.
7541 * Application receives now exactly same command reply arguments as
7542 the library receives from server. However, if ID is received the
7543 corresponding ID entry is returned to the application (eg. Client
7544 ID is mapped to correct SilcClientEntry entry and that is returned).
7545 Changed command_reply client operation due to this change.
7547 * Changed all ID's in commands and in command replys as ID Payloads.
7548 Change affected both client and server side codes.
7550 All ID's sent in SILC network (with execption of ID's in SILC
7551 Packet header) are sent in ID Payload to support variable length
7554 * Server now notifies nick changes and notifies all clients on
7555 the channels about the new nickname (about the new Client ID,
7558 * Implemented CMODE command to change channel modes. Supports all
7559 channel modes defined by the protocol specs except ban and invite
7560 lists. (Also, private channel key mode is supported but support for
7561 setting private channel key in client is missing, thus, this mode
7562 has no effect on client side (except that server requires that the
7563 client uses private channel key and normal channel traffic does not
7566 Also, invite mode works per se, but INVITE command does not work
7567 yet correctly, so you can set channel as invite only channel but
7568 inviting clients to the channel does not work (it is yet to be
7569 thought what's the best way to do it).
7571 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7572 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7573 Implemented CUMODE command to change user's mode on the channel.
7574 Supports all modes defined by the protocol specs.
7576 * Added NAMES command reply to return users modes on the channel.
7578 * Removed unnecessary and slow ciphers from lib/silccrypt.
7580 * Set SO_KEEPALIVE option to connection sockets by default.
7582 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7584 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7585 redefined the Notify Payload into protocol specs.
7587 * Added silc_id_payload_parse_id to get ID directly from raw
7590 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7593 accept searching by Client ID as well.
7595 * Added support for LEAVE and SIGNOFF notify types in client library.
7597 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7598 to parse ID Payload from raw data.
7600 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Added flags parameter into silc_ske_assemble_security_properties
7603 function in lib/silcske/silcske.[ch].
7605 * Changed notify client operation to fit better for notify messages
7606 sent by server. The notify payload received from server is now
7607 passed to the application (after parsing it to SilcNotifyPayload).
7608 It is application's responsibility to retrieve the arguments
7609 from the payload and show the message the way it wants. The message
7610 sent by server is implementation specific.
7612 * Changed public keys to comply with the protocol specification.
7613 Old public keys are not supported anymore and are not compatible.
7615 * Removed nickname from Channel Payload as the latest draft removed
7616 it. The client must resolve the nickname from the NAMES command
7617 reply received when it joined the channel.
7619 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7621 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Fixed some errors in protocol specification drafts.
7625 * Created lib/silccore/silcnotify.c to implement Notify Payload
7626 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7627 generic payloads described by protocol specifications. The file
7628 includes implementations for ID Payload and Argument Payload.
7630 * Changed Command Payload implementation to use the new Argument
7631 Payload. Changed command_xxxx_payload to command_payload_xxxx
7632 to comply with SILC coding conventions.
7634 * Added suppport for Argument Payload handling in Notify Payload
7635 implementation as protocol requires it. Added the new support
7636 into server and client lib as well.
7638 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Added support for multiple nicknames on same channel. [n] is
7641 added locally to the nickname if there are more than one same
7642 nicknames on the channel.
7644 * Server now sends all nicknames that matched WHOIS request.
7645 Client also shows the list received from server.
7647 * Added TOPIC command to client side. User can now set and show
7648 current topic on channel.
7650 * Added MOTD command to client and server. Also, server sends the
7651 motd when client connects to the server.
7653 * Changed version strings to comply ISO 8601.
7655 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7657 * Fixed protocol error handling in client library. It should now
7658 cope even if the SKE fails for some reason.
7660 * Made new protocol specification drafts for submitting to IETF.
7662 * Implemented TOPIC command to server in silcd/command.c.
7664 * Added two new notify types into lib/silccore/silcnotify.h:
7665 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7666 notify nickname change and topic setting/change on a channel.
7668 * API change of command_reply operation in client library. The
7669 application gets now the status type received from server as well.
7671 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7675 * Cras fixed and optimized the packet handling even further and
7676 it should work now. Minor change to the prototype of function
7677 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7679 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7681 * Added new function into lib/silcutil/silcschedule.[ch]:
7682 silc_schedule_with_fd to select() a specified fd. The function
7683 returns after timeout expires or data arrives or goes. The
7684 function is used by packet routines to wait that all data is
7685 received from network.
7687 * Fixed data reading from network in lib/silccore/silcpacket.c.
7688 The code now assures that all data is read from the fd and then
7689 continues packet processing. This was a bug fix since the code
7690 used to drop some data in some circumstances.
7692 * Added new function into lib/silcclient/client.[ch]:
7693 silc_client_start_key_exchange to start key exchange after
7694 connection has been established to server. The code internally
7695 now uses this funtion but its main purpose was to provide it
7696 for applications that perform their own connecting. After
7697 application has created a connection it merely calls this
7698 function to start the key exchange between client and server.
7699 The library takes care of everything else after that.
7701 Updated also lib/silcclient/README to explain the usage of
7704 * Do not send to application information that connection has
7705 been established. Application gets notified it by connect
7708 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7710 * Applied cras's patch to add silc_schedule_one function. The
7711 function runs scheduler once and returns.
7713 * Fixed the scheduler after cras messed it up. The timeout
7714 handling works now as it's supposed to work.
7716 * Added into lib/silccore/ silcnotify.h to include notify
7717 message types support. Changed silc_server_send_notify*
7718 functions, in server.[ch], to support those new notify types.
7719 Added the support for the notify types into client library,
7720 as well. Added new notify client operation into ops.h in
7723 * Changed silc_server_packet_send_to_channel to send normal
7724 packets instead of just channel message packets. The function
7725 is now used to send the notify packets to channels. It is not
7726 used to send channel message packets anymore, as server never
7729 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7730 va_arg()s as it seems to require it nowadays. I guess, if SILC
7731 is compiled with older va_arg() the new code should work anyway.
7733 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Splitted core library. Core library (lib/silccore) includes
7736 now only SILC protocol specific core (and common) components.
7737 Created new utility library (lib/silcutil) that includes more
7738 generic purpose stuff. The stuff for util library was taken
7739 from the old core library. This was minor and easy split.
7741 * Created SILC Client Library (lib/silcclient) that includes
7742 implementation of the SILC client without user interface. This
7743 was major move from silc/ directory. The code has been changed
7744 so that it is transparent towards the user interface. The
7745 silc/ directory includes now the same user interface as before
7746 and it uses the new client library. Read lib/silcclient/README.
7747 Basicly, the client library performs everything else related
7748 to SILC except user interface handling. Also, configuration
7749 files are considered to be part of user interface and library
7750 does not handle them.
7752 This change also changed a lot of structures, function naming etc.
7753 Most important change was that SilcClientWindow object was
7754 renamed to SilcClientConnection in the client library. Created
7755 also new file lib/silcclient/ops.h. Also added new files
7756 silc/local_command.[ch] and silc/client_ops.[ch].
7758 All these changes were made to make it easier for user interface
7759 designers to create what ever user interface for the SILC client
7762 It is also expected that the server will be moved to lib
7763 directory as well and SILC Server Library will be created;
7764 sometimes in the future.
7766 * Removed Local commands from lib/silccore/silccommand.h as
7767 they are application specific and new client library does not
7768 handle any of those anymore.
7770 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7771 old client implementation in silc/.
7773 * Added support for callback functions in SILC_LOG_* macros.
7774 Application can now set its own callbacks that will be called
7775 instead of using the default functions that will always print
7776 the debug messages to stderr (or stdout). Also, debugging can
7777 now be disabled by setting silc_debug to FALSE and re-enabled by
7778 setting it to TRUE. Note, that logging will still work even
7779 if debugging is disabled.
7781 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7782 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7783 silc_log_reset_debug_callbacks.
7785 * To enable debugging in silc client one must give now -d
7786 option on command line.
7788 * Changed silc_schedule_init to automatically allocate task queues
7789 if they are not allocated before calling it.
7791 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7793 * Added GMP 3.1 into math library.
7795 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7797 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7798 a channel in SILC network. The packet is used by servers and
7799 routers to notify other routers that user has left a channel.
7800 This little feature was missing until now. Added the feature
7801 to protocol specification as well.
7803 Added functions: silc_server_send_remove_channel_user and
7804 silc_server_remove_channel_user into server.[ch].
7806 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7807 lib/silccore/silcpacket.h. However, they are not implemented
7810 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7812 * Fixed joining to a channel and sending channel messages
7813 between server and router. The channel message sending should
7814 now work inside a cell.
7816 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Fixed the private message sending between server and router.
7819 The private message sending should now work inside a cell.
7821 * Added silc_server_replace_id into server.[ch] to replace
7822 existing ID in the SILC network.
7824 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7825 and silc_idlist_replace_server_id into idlist.[ch] in server.
7827 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7829 * Fixed the server to server connections. Server can again now
7830 connect to router. Router to router connections probably does
7833 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Added dynamic protocol registering support. Now protocols can
7836 registered and unregistered on the fly. Patch by cras.
7838 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Added lib/contrib directory to hold routines that some platforms
7841 don't have but are needed by SILC.
7843 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7844 into lin/contrib to provide getopt() and getopt_long() for
7845 those who don't have it.
7847 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * Added AWAY command to client. When away message is set and
7850 client receives a private message packet the client automatically
7851 replies to the sender with the away message.
7853 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7854 bug seemed to be the cause of recent problems when compiling
7857 * Added version detection support to SKE protocol specification
7858 and added the new changes to the SKE implementation as well.
7859 There were other minor changes in the SKE protocol as well.
7861 Many changes in lib/silcske/silcske.[ch] and in
7862 lib/silcske/payload.[ch].
7864 * Added ^U functionality, clear input line. Patch from cras.
7866 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Mainly small bugfixes on core library. Fixed some debugging
7869 logging and buffer overflow in silclog.c.
7871 * Updated config.sub and config.guess on the distribution tree.
7873 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7875 * Added command lagging support in server. Client may execute
7876 commands now only once in two seconds.
7878 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Optimized packet reception. MAC computation and checking is now
7881 also more optimized. A lot previously duplicated code is now
7882 used as generic by both client and server.
7884 * Fixed key pair generation in clientutil.c
7886 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7888 * Added into lib/silccore/silcbufutil.[ch] new function;
7889 silc_buffer_realloc.
7891 * Moved generic packet sending/encryption functions to
7892 lib/silccore/silcpacket.[ch] from client and server. Some
7893 rewriting of the functions.
7895 * Moved all generic packet reception/decryption functions to
7896 lib/silccore/silcpacket.[ch] from client and server. The
7897 packet processing is now much cleaner in both client and server.
7898 These were major changes in both client and server.
7900 * Created many common functions in server to do packet sending.
7901 Previously code were duplicated a lot, this has been removed
7904 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7906 * Rewrote major parts of the ID cache system. Don't know
7907 whether it is better now or not but at least the API is more
7910 * Major rewrite on ID cache stuff on client because of the ID
7911 cache API changes. Added idlist.c to client.
7913 * Also major rewrite on ID cache stuff on server as well.
7914 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7915 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7916 in hand, instead they are all put into the ID cache system now.
7917 All server_idlist_* routines uses ID cache now instead of
7918 traversing its own lists (those lists does not exist anymore).
7919 SilcIDList though still exists. Also, SilcXXXEntry's are
7922 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Finally made the SKE implementation compliant to the protocol
7925 specification. All mp integers are now binary encoded as
7926 opposed being HEX encoded.
7928 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7931 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7932 functions: silc_[encode/decode]_pem. Also added function
7933 silc_encode_pem_file to PEM encode with newlines ('\n') for
7936 * SILC public keys are now encoded either PEM or binary. Same
7937 option is for private keys as well. By default private keys
7938 are binary encoded and public keys PEM encoded. Silly HEX
7939 encoding were removed.
7941 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7942 function to create fingerprints.
7944 * Fixed a bug in SHA1; does not change the original data anymore.
7946 * Partly implemented INFO command on client and server side.
7947 Fixed CLEAR command. Changes to SERVER command; show current
7948 server(s) when giving command without arguments. Added
7949 VERSION command to client.
7951 * Added check to server that unregistered connections cannot
7952 execute commands (unless it is specificly allowed).
7954 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Fixed screen refresh.
7958 * Fixed channel joining bug from client. On some circumstances
7959 client tried to join to a channel it had already joined.
7961 * Added public key verification process into client's protocol.c.
7962 The client now verifies the public key from user and saves
7963 it into ~./silc/serverkeys/ directory.
7965 Added into: clientutil.[ch]: silc_client_verify_server_key.
7967 * Changed SKE protocol's silc_ske_initiator_finish function
7968 to accept callback function that verifies the received public
7969 key. Removed old silc_ske_verify_public_key function.
7971 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7974 silc_pkcs_private_key[_data]_set.
7976 * Made the password and public authentication more cleaner in
7977 server's protocol.c.
7979 * Removed historic and obsolete protocol `channel_auth' from
7980 both client and server.
7982 * Removed wrong way of sending command status messages from
7983 server to client in server's command.c. The old way violated
7984 protocol specification.
7986 Changes to silccore/silccommand.[ch]: removed
7987 silc_command_encode_status_payload -> not needed anymore,
7988 changed silc_command_encode_payload_va to accept extra
7989 argument on variable argument list. The argument type must
7990 now be provided to the function. Also, added new function:
7991 silc_command_encode_reply_payload_va which is same as
7992 normal command_encode_payload_va except command status type
7993 is provided as extra argument.
7995 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7997 * Added ~./silc directory handling. The directory includes the
7998 public and private keys for the client.
8000 Added silc_client_check_silc_dir, silc_client_create_identifier
8001 and silc_client_load_keys.
8003 * Implemented SILC protocol compliant public key. Added public
8004 and private key saving to and loading from files.
8006 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8007 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8008 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8009 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8010 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8012 Implemented: silc_pkcs_save_[public/private]_key[_data] and
