1 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Made some structure optimizations. SFTP memory FS MemFSEntry
4 entry structure. Optimized SilcTask structure. Optimized
5 SilcPacketContext structure.
7 Affected files lib/silcsftp/sftp_fs_memory.c,
8 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
10 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
12 * And yet again reverted back the config thing since Johnny
13 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
16 * Fixed memory leaks from config object. Affected files are
17 silcd/serverconfig.[ch].
19 * Added support for adding new connections to the server in rehash.
20 After rehash they take effect.
22 Added support for changing the maximum allowed connections in
23 rehash. The number can grow but going smaller is not supported.
25 Added function silc_server_num_sockets_by_remote to the
26 silcd/server_util.[ch].
28 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
30 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
32 * Added preliminary checking during config parsing for a valid
33 public/private key and removed further checks in the code.
34 Affected files are silcd/serverconfig.[ch], server.c.
36 * Moved functions silc_server_drop() and silc_server_daemonise()
37 from server.c to silcd.c since they are stricly related to
38 the application activity.
40 * Reverted a small part of the automatic ref/unref since
41 it caused a double unref in some situations. Affected
42 files are silcd/silcd.[ch], server.c, serverconfig.c.
44 * Added some .cvsignore files in the lib directory.
46 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
48 * Fixed silc_net_gethostbyaddr to correctly resolve by
49 address. Affected file lib/silcutil/silcnet.c.
51 * Fixed the notify relaying to client. The HMAC to be used
52 with relayed packets ws wrong and caused decryption failure
53 at the client end. Affected file is silcd/packet_receive.c.
55 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
57 * Created new branch silc_protocol_1_0_branch.
59 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
61 * Changed the silc_server_config_* routines to be SilcServer
62 independent. They are now officially application specific code
63 and not part of generic server implementation. Affected files
64 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
66 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
68 * Added automatic referencing of config context in the
69 silc_server_config_alloc, and automatic unreferencing in the
70 silc_server_config_destroy. Affected files are
71 silcd/serverconfig.[ch], silcd/silcd.c.
73 * Fixed the silc_log_quick handling in the logging routines.
74 It didn't log quickly when it was TRUE. Affected file is
75 lib/silcutil/silclog.c. Also the flush delay was set even
76 if it was 0 in config file. Affected file is
79 * Added support for changing key pair of the server in rehash.
80 Affected file silcd/server.c.
82 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
84 * Fixed the TOPIC_SET notify to not cras. It changed the topic
85 too early, before getting the channel entry. Affected file
86 is silcd/packet_receive.c.
88 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
90 * Added functions silc_server_config_[ref/unref], these are used
91 to prevent that the config object is destroyed.
93 No longer directly affect global variables silc_log_quick and
94 silc_log_delay, they are first cached inside the config object
95 and then applied with silc_server_config_setlogfiles().
97 silc_server_config_set_defaults() is now internal to
98 serverconfig.c, there are no reasons to show this internal stuff
101 Affected files are silcd/serverconfig.[ch].
103 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
104 fprintf's to stderr, since some code may be executed again after
105 the server went into the background. Affected files are
108 * Added rehash support. Added function silc_server_rehash() that
109 will perform all the basic tasks of the rehashing procedure.
111 * Added command line option `-x, --hexdump'. This will enable the
112 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
113 The option `--hexdump' implies `--debug'.
115 * Fixed a bad bug in the logging APIs (silcutil library) where
116 the application would crash after calling silc_log_reset_all().
118 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Fixed the KICKED notify handling in client library to
121 correctly remove the channel and all entries from the
122 channel when I was kicked. This bug crashed the client.
124 Fixed yet another but in KICKED notify handling to remove
125 the kicked client correctly from the channel.
127 Affected file is lib/silcclient/client_notify.c.
129 * Fixed a minor bug in looking up correct client entry
130 in KICKED notify in server. Affected file is
131 silcd/packet_receive.c.
133 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
134 sources correctly to distribution. Fixes --with-gmp option.
136 * Removed the manual rehashing from ID Cache, and changed it
137 to use the SILC Hash Table's auto rehash feature. Affected
138 file is lib/silccore/silcidcache.c.
140 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Fixed a bug in the silc_client_nickname_format function that
143 handles the multiple same nickname formatting. Two clients
144 with same nickname caused problems after the first one left
145 and rejoined. It didn't format the nickname correctly.
146 Affected file is lib/silcclient/idlist.c.
148 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
150 * Don't change the topic if olod topic is same as new one.
151 Affected file is silcd/packet_receive.c.
153 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
155 * Added cross-reference support to the SILC Documentation
156 generator. All types across all HTML files are now cross-
157 referenced. Affected files util/robodoc/generator.c and
158 scripts/silcdoc/silcdoc.
160 * Added file lib/silcutil/silctypes.h to include all the
161 arithmetic type definitions and some macros. Removed
162 includes/bitmove.h and moved macros to silctypes.h.
164 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
166 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
168 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
170 * Added `type' argument to silc_id_payload_parse_id function which
171 now returns the type of the ID to the sent pointer. Affected
172 file is lib/silccore/silcid.[ch].
174 * Added check for CMODE_CHANGE notify type that mode change is
175 allowed by the sender. Affected file silcd/packet_receive.c.
177 * Added check for CUMODE_CHANGE notify type that mode change is
178 allowed by the sender. Affected file silcd/packet_receive.c.
179 Added the ID type as CUMODE_CHANGE notify type as argument
180 to the `notify' client operation. Affected files are
181 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
183 * Added function silc_client_add_server to the client library.
184 Added support for resolving also channel and server info when
185 received unknown entity in notify packet. Affected files are
186 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
188 * Added function silc_command_get_status to return the command
189 status from the command reply's argument payload. Affected files
190 are lib/silccore/silccommand.[ch].
192 * Added check for KICKED notify type that the kicking is
193 allowed by the client. Affected file silcd/packet_receive.c.
195 * Created function silc_get_input which can be used to get input
196 (echo on or off) from user on command line. Affected files are
197 lib/silcutil/silcutil.[ch].
199 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
201 * Optimized silc_server_packet_relay_to_channel function.
202 Added new function silc_channel_message_payload_encrypt which
203 can be called directly if channel message payload needs to
204 be encrypted and is already encoded (no need to call _encode
205 function). Packet relaying is now done by router without any
206 extra memory allocations. Affected files are
207 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
210 * Fixed the INVITE notify handling. It took wrong arguments
211 as invite list and invite delete. Affected file is
212 silcd/packet_receive.c.
214 * Added check for TOPIC_SET notify type that the topic change is
215 allowed by the client. Affected file silcd/packet_receive.c.
217 * Added check for INVITE notify type that inviting is allowed by
218 the client. Affected file silcd/packet_receive.c.
220 * Changed the silc_server_client_on_channel to return the
221 SilcChannelClientEntry as well. Moved the function
222 silc_server_check_cmode_rights to server_util.[ch].
223 Affected files are silcd/server_util.[ch], silcd/command.c.
225 * Added function silc_server_check_umode_rights to check whether
226 changing client's user mode is allowed. Added check for
227 UMODE_CHANGE notify type that the umode change is allowed
228 by the client. Affected files are silcd/server_util.[ch],
229 silcd/packet_receive.c and silcd/command.c.
231 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
233 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
234 ID length. It ignored that ID can be IPv6 based as well.
235 Affected file lib/silccore/silcpacket.h.
237 * Fixed the silc_id_id2str and silc_id_str2id to take the
238 IPv6 address offset's into consideration. Affecte file is
239 lib/silccore/silcid.c.
241 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Fixed the internal Unix scheduler functions to check for
244 NULL context they may receive. The affected file is
245 lib/silcutil/unix/silcunixschedule.c.
247 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
249 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
250 can specify different directory with --home command line
251 parameter. Affected files irssi/src/silc/core/client_ops.c,
254 * SILC-specific commands aren't now executed if the active server
255 isn't of SILC-type, so there won't be problems with having
256 IRC and SILC protocol support in same client. Affected files
257 irssi/src/silc/core/silc-channels.c, silc-servers.c,
260 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Improved the signal support in SILC Schedule. Added new
263 function silc_schedule_signal_call which is used by application
264 to mark a signal to be called. It is now safe to perform
265 any kind of tasks in signal callbacks since it is guaranteed
266 that the application specified signal callback is called
267 after the signal is over. Affected files are
268 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
270 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Added `name' field to SilcChannelPrivateKey to represent
273 application given name for the key. Moved also the context from
274 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
275 Added the `name' argument also to the function
276 silc_client_add_channel_private_key.
278 Added function silc_client_current_channel_private_key to set the
279 current channel private key in use.
281 Added "change" command to KEY command which can be used to change
282 the current channel private key. Bound the command also to
285 Also affected files lib/silcclient/client_channel.c,
286 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
288 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Added silc_rng_get_byte_fast function in to the
291 lib/silccrypt/silcrng.[ch].
293 * Changed the interface of silc_packet_assemble and the
294 silc_packet_send_prepare. If silc_packet_assmble is now
295 called the application does not call silc_packet_send_prepare
296 because the library will call it automatically. These
297 interfaces now also return a reference to the outgoing buffer
298 which includes the assembled packet, which the application can
299 use to encrypt the packet.
301 Affected files are lib/silccore/silcpacket.[ch],
302 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
303 silcd/packet_send.c, server_backup.c and packet_receive.c.
305 * Fixed a packet sending bug on very high load, where outgoing
306 packet queue wasn't handled correctly and packets got corrupted.
307 Affected files are lib/silcutil/*/silc*sockconn.c,
308 lib/silcclient/client.c and silcd/server.c.
310 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Added macro SILC_PACKET_DATALEN which can be used during
313 packet assembling to check whether the data to be added to
314 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
315 len is truncated until it fits it.
317 Added checks for maximum length of channel message payload and
318 private message payload also.
320 Added checks for maximum packet length in server and in
323 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
324 lib/silcclient/client.c, lib/silccore/silcchannel.c and
325 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
326 lib/silcclient/client_prvmsg.c.
328 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Added silc_server_packet_queue_purge call to the
331 silc_server_disconnect_remote to assure that all data in the
332 queue before disconnecting is sent to the network. Affected
335 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
337 * Added the deleting of server's own ID cache entry to the
338 silc_server_free function. Free also everything else that
339 has been allocated in silc_server_init. The affected file
342 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
344 * Added functions silc_parse_version_string, silc_version_to_num,
345 and silc_ske_parse_version to parse SILC protocol style version
346 strings. Affected files lib/silcutil/silcutil.[ch] and
347 lib/silcske/silcske.[ch].
349 * Added new configuration params: version_protocol, version_software
350 and version_software_vendor to specify what version the remote
351 host must at least be to be able to connect to server. The vendor
352 string can be regex matched too. Added new function
353 silc_server_connection_allowed to check maximum number of allowed
354 connections, and allowed versions for incoming connections.
355 Affected files are silcd/server.c, server_util.[ch] and
358 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
360 * Added preliminary support for signals in scheduler. The
361 signals we care about are now blocked always when the scheduler
362 is locked. This way we can synchronise the use of signal with
363 scheduler. It is guaranteed that when signal occurs the scheduler
364 is not locked, and thus new tasks can be safely added to the
367 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
368 to silc_schedule_internal_init and silc_schedule_internal_uninit.
369 Added new platform specific routines
370 silc_schedule_internal_signals_[un]block and
371 silc_schedule_internal_signal_[un]register.
373 Added new functions to SILC Schedule API:
374 silc_schedule_signal_[un]register. Each signal that application
375 is going to use should be registered to the scheduler.
377 Affected files are lib/silcutil/silcschedule.[ch],
378 lib/silcutil/*/silc*schedule.c.
380 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
382 * Check for unauthenticated client and server in the
383 silc_server_new_client and silc_server_new_server functions.
384 Affected file silcd/packet_receive.c.
386 * Added function silc_string_is_ascii to check whether given
387 string is 7-bit ASCII string. Affected files are
388 lib/silcutil/silcutil.[ch].
390 * Added function silc_id_is_valid_server_id into the
391 silcd/serverid.c and added checking for valid Server ID's in
392 silc_server_new_server. The Server ID must always be based
393 on the server's public IP address.
395 * Added logging of DISCONNECT packet message in the server.
396 Affected file silcd/server.c.
398 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Changed all library interfaces that use Global RNG to also
401 accept SilcRng as argument. Affected files are
402 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
403 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
404 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
405 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
408 * Added function silc_pkcs_generate_key to the
409 lib/silccrypt/silcpkcs.[ch] for applications so that they
410 don't need to do pkcs->pkcs->init calls anymore.
412 * Remove SilcSocketConnection from the SFTP API since it really
413 wasn't needed there. The application has the information
414 saved in its contexts anyway and the SFTP layer doesn't need
415 know about it. Affected files lib/silcsft/silcsftp.h and
416 lib/silcsftp/sftp_[server/client].c.
418 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
419 The SilcSimContext is not SilcSim.
421 * Fixed possible buffer overflows in silc_id_render in the
422 lib/silcutil/silcutil.c.
424 * On EPOC the global crypto module lists are not used at all
425 in the crypto library. Added support for using the constant
426 algorithm list on EPOC. Affected files are
427 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
430 * Fixed the handling of third parameter of KICKED notify, since
431 it was mistakenly updated to SILC Protocol 1.0 even though it
432 is to be included in 1.1. Since it is not in 1.0 it is not
433 mandatory, and this fix now handles it only if it is provided,
434 and it is not error if it is not provided. Affected file
435 lib/silcclient/client_notify.c.
437 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
440 client. Affected file irssi/src/silc/core/client_ops.c.
442 * Merged with Irssi 0.8.4 from irssi.org CVS.
444 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
446 * Check for valid socket connection in client entries before
447 sending any messages. Fixes a crash, but doesn't fix some
448 other underlaying bug that is lurking there. Affected
449 file silcd/packet_send.c.
451 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
453 * $usermode, $cumode and $cumode_space expandos shouldn't do
454 anything with non-SILC server records. Affected file
455 irssi/src/silc/core/silc-expandos.c
457 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
459 * Fixed the silc_net_check_[host/local]_by_sock to support
460 IPv6 bound sockets as well. Now they can return IPv6 addresses
461 as well. Affected file lib/silcutil/silcnet.c.
463 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
464 Affected lib/silcutil/unix/silcunixnet.c.
466 * Fixed ID rendering (at least on some platforms, not NetBSD)
467 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
469 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
471 * Added silc_hash_public_key and silc_hash_public_key_compare
472 functions to be used with SilcHashTable. They can be used to
473 hash public keys and compare public keys in hash table. Affected
474 file lib/silcutil/silcutil.[ch].
476 * Added support for specifying multiple public keys for Client
477 connection section in server configuration file. This makes it
478 possible to accept multiple public keys from same host, or to
479 make a section that accepts any incoming host, and have the
480 accepted public keys listed in the section.
482 Added functions silc_sever_[find/get]_public_key, added the
483 support for this actually to all connection sections but only
484 the Client section is currently allowed to specify multiple
487 Affected files are silcd/server.c, server_internal.h,
488 command.c, protocol.c, server_util.[ch], packet_receive.c.
490 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
492 * Merged Irssi 0.8.2 from irssi.org CVS.
494 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
496 * If silc_debug is TRUE, also output standard logging messages
497 to stderr with the debug output.
499 Made silc_log_reset_all() flushing all channels before returning.
500 Also fixed some documentation typos.
502 Affected files are lib/silcutil/silclog.[ch].
504 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Fixed the server to check correctly the amount of connections
507 from single host, by checking also the type of the connection.
508 Fixed also the comparison of number of connections and number
509 of allowed connections. Affected files are silcd/server.c,
512 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Fixed the USERS command reply to save the user's mode on the
515 channel as well. Fixed JOIN command reply to check whether a
516 client is on channel already and not join it twice. Affected
517 file lib/silcclient/command_reply.c.
519 * Added new file silc-expandos.c into irssi/silc/core/ to return
520 various stuff for various signal for the statusbar etc. updating.
521 Now Irssi SILC client prints channel user modes etc. on the
524 * The user mode (like server/router operator changes) is now shown
525 on the Irssi SILC client's statusbar. The affected files are
526 irssi/src/silc/core/client_ops.c, silc-expandos.c.
528 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
530 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
531 to SILC_SCHEDULE_[UN]LOCK macros.
533 * Added more error printing to logs in server code. Affected

591 application does not need to define them. Affected file
592 includes/silcincludes.h.
594 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
595 old name went against naming convention. Applications now
596 include "silcclient.h" instead of "clientlibincludes.h".
597 Removed includes/clientlibincludes.h, it is redundant now.
599 * Renamed includes/version.h to silcversion.h.
601 * Added really preliminary support for OS/2 into the util
602 library. Only thread & mutex API is implemented, others
603 are still to be implemented. Created the lib/silcutil/os2/
604 directory. Created also file includes/silcos2.h.
606 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

637 * Added `user_count' to the SilcChannelEntry which now tells the
638 number of users on the channel. The user count is now saved
639 in normal server of global channels as well. Affected files
640 silcd/server.c, idlist.h, packet_receive.c and command.c.
642 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

653 client_entry->channels hash table everytime nick is changed.
654 Affected file lib/silcclient/client.c.
656 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
658 * ROBOdoc documented the lib/silcske/silcske.h, and improved
659 the SKE interface a bit.
661 * Fixed padding problem in PKCS#1. The padding was not actually
662 random since the random number generator was used incorrectly.
663 This security bug affects only when encrypting with PKCS#1, and
664 it is not currently used at all in SILC. SILC only use signing
665 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
667 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

733 * Added new configuration options and blocks:
734 keepalive_secs, reconnect_count, reconnect_interval,
735 reconnect_interval_max, reconnect_keep_trying and
736 require_reverser_lookup. Added ConnectionParam block, and
737 implemented the connection parameters when connecting as
738 initiator and when accepting connections as responder.

746 algorithm parts and created new file silcalgs.conf, that
747 is now included from the example_silcd.conf.in.
749 * Optimized the silc_server_connect_to_router_second to take
750 the connection configuration object from the SilcServerConnection
751 object instead of finding it during the connecting phase.
752 Added the configuration object to SilcServerConnection struct.
753 Affected files silcd/server_internal.h, server.c.

777 authentication to be set at the same time.
779 Added `prefer_passphrase_auth' setting in config file which
780 can be used to set to prefer passwd auth if both passwd and
781 public key is set. If not set, public key is preferred.
782 This has effect only when being initiator (responder will try
785 Added support for authentication with passphrase and public key
786 at the same time. The passphrase is tried first always since
787 it is faster to check.
789 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
791 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

837 * Fixed the file transfer's key agreement payload to include
838 zero port also if the hostname is NULL because it could not
841 Call file transfer monitor callback now also if error occurs
842 during key agreement protocol.
844 Changed the silc_client_file_send interface to return the
845 SilcClientFileError instead of session id. The session ID
846 is returned into pointer provided as argument.

865 * Fixed the channel message payload decryption in the function
866 silc_channel_message_payload_decrypt to not modify the original
867 buffer before it is verified that the message decrypted
868 correctly. Otherwise, next time it is called with correct
869 channel key it won't encrypt since the payload is corrupted.
870 Affected file lib/silccore/silcchannel.c.
872 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

886 become invalid in the callback but it was referenced after
887 the callback returned.
889 Do not allow auto rehashing of hash table during the
890 silc_hash_table_foreach operation, for same reasons as it is
891 not allowed for SilcHashTableList. Affected files are
892 lib/silcutil/silchashtable.[ch].
894 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

915 users list to SilcHashTable. The affected files are
916 lib/silcclient/idlist.[ch].
918 * Fixed a bug in hash table tarversing. While the hash table
919 is traversed with SilcHashTableList the table must not be
920 rehashed. It is now guaranteed that auto rehashable tables
921 are not rehashed while tarversing the list. Also defined that
922 silc_hash_table_rehash must not be called while tarversing
923 the table. Added function silc_hash_table_list_reset that must
924 be called after the tarversing is over. The affected files are
925 lib/silcutil/silchashtable.[ch].
927 * Changed all hash table traversing to call the new
928 silc_hash_table_list_reset in server and in client library.
930 * Added function silc_client_on_channel to return the
931 SilcChannelUser entry if the specified client entry is joined

947 sender's old command identifier was not saved back to the
948 sender's command context, fixed now. The affected file is
951 * Create the key in JOIN command of the router did not return
952 the channel key, added check for this. Affected file is
955 * Fixed a channel ID update bug in JOIN command reply. Do
956 not directly upgrade the ID but call the function
957 silc_idlist_replace_channel_id if the ID was changed.
958 Affected file silcd/command_reply.c.
960 * Fixed memory leaks from command calling if it would fail.
961 Affected file silcd/command.c.

988 functions. Affected file silcd/server.c.
990 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
991 which ID was changed. This way the router will send the
992 user list for the channel again, and server won't be in
993 desync in some rare circumstances. Affected file is
994 silcd/packet_receive.c.
996 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1078 method if the IP address based filename is not found.
1080 Fixed the GETKEY command to save the fetched server key
1081 in correct filename.
1083 Print the remote server's hostname now when new key is
1084 received during connection process. Affected file is
1085 irssi/src/silc/core/client_ops.c.
1087 * Return always our own public key to the client if it asks
1088 for it with GETKEY command. Affected file silcd/command.c.
1090 * Removed the use_auto_addr variable from default config
1091 file since it was in wrong section. Affected file is
1094 * Fixed TOPIC_CHANGE notification to not route it when it
1095 was sent using silc_server_send_notify_to_channel function.
1096 Affected file silcd/command.c.
1098 * Fixed silc_server_send_notify_kicked to send the kicker's
1099 Client ID also, it was missing. Affected files are
1100 silcd/command.c, silcd/packet_send.[ch].
1102 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Do not save client history information in SERVER_SIGNOFF.
1105 Fixes the bug in normal server that it does not detect
1106 the client becoming valid after the server becomes back
1107 online. Affected file silcd/server_util.c.
1109 * Added `sock_error' field into the SilcSocketConnection
1110 context. When error occurs during socket operation (read
1111 or write) the error is saved. Added also new function
1112 silc_socket_get_error to return human readable socket error
1113 message. Affected files are lib/silcutil/silcsockconn.[ch],
1114 lib/silcutil/unix/silcunixsockconn.c, and
1115 lib/silcutil/win32/silcwin32sockconn.c.
1117 * The server now prints the socket error message in the
1118 signoff for client. Affected file silcd/server.c.
1120 * Fixed the `created' channel information sending from router
1121 to server in JOIN command. Checks now whether the channel
1122 really was created or not and set it according that.
1124 Fixed the JOIN command to use the client entry's current
1125 ID during the joining procedure instead of the one it sent
1126 in the command (it is checked though), since it can change
1127 between the packet processing and command processing, and
1128 would just case unnecessary pain in the client end. Affected
1129 file silcd/command.c.
1131 * Fixed a channel key payload sending to use correct channel
1132 ID when the server was forced to change the channel's ID by
1133 router. Router sent the key payload with the old Channel ID.
1134 Affected file silcd/packet_receive.c.
1136 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * Call silc_server_save_channel_key only if the key payload
1139 was provided in the JOIN command's command reply. Affected
1140 file silcd/command_reply.c.
1142 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed silc_mp_sizeinbase to return the value correctly with
1145 MPI. Affected file lib/silcmath/mp_mpi.c.
1147 * Fixed the stop_server signal to correctly stop the scheduler
1148 and gracefully stop the server when SIGTERM or SIGINT signals
1149 are received. Affected file silcd/silcd.c.
1151 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1153 * Simple handling of TERM and HUP signals. Also added some log
1154 flushing call around. Affected file is
1157 * Fixed small bugs in silclog.c. Now buffering output will take
1158 effect after 10 seconds since startup: This will ensure that
1159 no important startup messages are lost. Also output redirection
1160 will preserve original format ([Date] [Type] message).
1161 Affected file is lib/silcutil/silclog.c.
1163 * Added two options to the config file, in the logging section:
1164 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1165 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1167 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1169 * Do not print the warning about log files not being initialized
1170 more than once to avoid excess logging. Affected file is
1171 lib/silcutil/silclog.c.
1173 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1174 the SIM copying in make install in Makefile.am.pre.
1176 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1178 * Rewritten silclog APIs. Globally interesting changes follows:
1179 silc_log_set_files() changed to silc_log_set_file().
1180 silc_log_set_callbacks() changed to silc_log_set_callback().
1181 ROBOdoc documented silclog header file.
1182 SilcLogCb now returns bool to wether inihibit the default
1183 handler or not (to keep the old behaviour return always TRUE).
1184 The new APIs should also fix the problem of the
1185 silcd_error.log file that was written in the current directory.
1188 Log files streams will remain opened after silc_log_set_file()
1189 call, means less CPU usage notably on high traffic servers.
1190 File streams are now full buffered, and flushed to the disk
1191 every 5 minutes, lesses HD activity and CPU usage.
1192 Messages can be redirected, allowing admins to configure
1193 one single logfile for all server messages.
1194 the silc_log_quick global variable to activate fast-logging.
1195 Affected files lib/silcutil/silclog.[ch]
1197 * Changed some code to conform new silclog APIs. Affected
1198 files are doc/example_silcd.conf.in, silcd/server.c
1199 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1202 * Fixed a memory leak that could occur in some situations.
1203 Affected file silcd/serverconfig.c.
1205 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1207 * Added the silc_client_del_client to remove the client from
1208 all channels as well. Affected file lib/silcclient/idlist.c.
1210 * Fixed the client library to correctly remove the client
1211 from all channels when the client entry is being destroyed.
1212 Affected file lib/silcclient/client_notify.c, command.c.
1214 * Added auto-nicking support to the client library. If the
1215 applicatio now sets client->nickname it will be sent to the
1216 server after connecting by the library. This way for example
1217 SILCNICK (or IRCNICK) environment variables will have effect
1218 and always change the nickname automatically to whatever
1219 it is wanted. Affected file lib/silcclient/client.[ch].
1221 * Renamed silc_server_command_bad_chars to the
1222 silc_server_name_bad_chars and moved it to the
1223 silcd/server_util.[ch]. Added also new function
1224 silc_server_name_modify_bad to return nickname that
1225 includes bad characters as new nickname without those
1226 bad characters. This check and modify is now used in
1227 silc_server_new_client when the username is initially set
1228 as nickname, so it must be checked to be valid nickname.
1229 Affected file silcd/packet_receive.c.
1231 * The nickname length is now taken from the packet for real
1232 and not trusted to strlen() since it clearly can return
1233 wrong length for nickname including bad characters. This
1234 also applies to channel names. Affected file silcd/command.c.
1236 * Removed the lib/silcsilm/modules directory. Modules are now
1237 compiled into the lib/silcsim. Fixed the copying of the
1238 modules to follow symbolic links in Makefile.am.pre.
1240 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1242 * Fixed silc_string_regexify list creation. Fixes bugs with
1243 BAN and INVITE commands in server. The affected file is
1244 lib/silcutil/unix/silcunixutil.c.
1246 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1248 * Removed the command destructor entirely from the server's
1249 command and command reply routines. It is not needed, and
1250 its usage was buggy and caused crashes. Affected files are
1251 silcd/command[_reply].[ch].
1253 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * Cancel protocol and NULL sock->protocol if timeout
1256 occurred during protocol. Affected file silcd/server.c.
1258 * Cancel protocol timeouts always before calling the final
1259 callback, to assure that after final callback is called
1260 no other state will be called for the protocol anymore.
1261 Affected file silcd/protocol.c.
1263 * Print error log if incoming connection configuration could
1264 not be found. Affected file silcd/server.c.
1266 * Fixed JOIN command to correctly save the founder mode
1267 to the client on normal SILC server, when the channel
1268 was created by the router. Affected file silcd/command.c.
1270 * Fixed LIST command (hopefully) to send correct reply
1271 packets. Affected file silcd/command.c.
1273 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1275 * The silc_packet_receive_process now returns FALSE if the
1276 read data was invalid packet, and TRUE if it was ok.
1278 The server now checks that if unauthenticated connection
1279 sends data and its processing fails the server will close
1280 the connection since it could be a malicious flooder.
1282 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1284 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Make sure the warning about error opening a log file is
1287 printed only once and not everytime it fails (produces
1288 too much useless log). Affected file lib/silcutil/silclog.c.
1290 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1292 * Made the silc_server_daemonise() function more readable.
1293 Affected file silcd/server.c.
1295 * Pid file is now optional, the user may comment it out from
1296 the config file. Removed define SILC_SERVER_PID_FILE, we
1297 don't need a default any longer. Affected file
1298 configure.in.pre, lib/Makefile.am.pre.
1300 * Make some use of the pid file. The server now dies at startup
1301 if it detects a valid pid file on his path. The server would
1302 die anyway in this circumstance, because of the bind() failure.
1303 Affected file silcd/silcd.c.
1305 * No longer compiling lib/dotconf.
1307 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Fixed JOIN command parsing not to crash. Affected file
1310 lib/silcclient/command.c.
1312 * Fied the NICK_CHANGE notify to add the new client entry
1313 even it is resolved. This removes an <[unknown]> nick
1314 thingy bug in the client. Affected file is
1315 lib/silcclient/client_notify.c.
1317 * Do not try to allocate 0 bytes (efence does not like it)
1318 in lib/silccore/silccomand.c when encoding payload.
1320 * Do not take IRCNICK as nickname in Irssi SILC client since
1321 it is not possible to set nickname before hand connecting
1322 the server (TODO has an entry about adding auto-nicking
1325 * Changed the silc_server_command_pending to check whether
1326 there already exists an pending entry with the specified
1327 command, command identifier and pending callback. This is
1328 to fix IDENTIFY and WHOIS related crashes that may register
1329 multiple pending commands with same identifier. Affected
1330 file silcd/command.c.
1332 * Fixed the server to reconnect to the router even if it
1333 was already reconnecting and EOF was received. This to
1334 fix a possibility that the server wouldn't ever try to
1335 auto-reconnect to the router. Affected file silcd/server.c.
1337 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1339 * Fixed the server's password authentication to use the
1340 length of the locally saved password, and not the one
1341 sent in the packet. Affected file silcd/protocol.c.
1343 * Fixed same password authentication problem in the
1344 Authentication Payload handling routines in
1345 lib/silccore/silcauth.c.
1347 * Yet another password authentication problem fixed with
1348 channel password handling in silcd/command.c.
1350 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * If first character of string in silc_parse_userfqdn is '@'
1353 then do not parse it. Affected file is
1354 lib/silcutil/silcutil.c.
1356 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed minor bug in IDENTIFY command reply sending, which
1359 caused various weird problems during JOIN when it was
1360 resolving names for users. Affected file silcd/command.c.
1362 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Fixed the IDENTIFY command reply sending to chech better valid
1365 clients. It was possible to send incomplete list of replies.
1366 Affected file silcd/command.c.
1368 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Added silc_client_command[s]_[un]register functions now to
1371 dynamically register the commands in client library. Removed
1372 the static table of commands. This allows the client library
1373 to call commands without causing the application to know about
1374 what commands library has called.
1376 Removed the INFO command reply kludge to detect when the command
1377 was called by library. Now library use its own command reply
1378 function for INFO command.
1380 Added function silc_client_command_call to call a command.
1381 Application can use it to call command, not access the structure
1384 Now all commands that are sent by the client library (not
1385 explicitly sent by application) use own command reply functions.
1387 Affected files around lib/silcclient/ and in
1388 irssi/src/silc/core/.
1390 * Fixed the WHOIS command reply sending to chech better valid
1391 clients. It was possible to send incomplete list of replies.
1393 Fixed the WHOIS and IDENTIFY to send the request to router
1394 if normal server did not do it and did not find any results.
1396 Affected file silcd/command.c.
1398 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Moved the internal data from SilcClient context into its
1401 own file, not accesible to application. Affected files
1402 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1403 and other files in client library.
1405 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Added doc/examples installation target in Makefile.am.pre.
1410 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1413 commands the found client entry will be removed from the
1414 cache, after notifying application about the error. Affected
1415 file lib/silcclient/command_reply.c.
1417 * Changed the /MSG to check for exact nickname user gave, and
1418 not let `nick' match `nick@host' if it is only one found. Now,
1419 user must type the exact nickname (like nick@host2) even if
1420 there are no more than one same nicks found. This is to avoid
1421 a possibility of sending nickname to wrong nickname since
1422 `nick' could match `nick@host'. Affected file is
1423 irssi/src/core/silc-servers.c.
1425 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Do not print "you are now server operator" or similar when
1428 giving /away command. Affected files are
1429 irssi/src/silc/core/client_ops.c, silc-servers.h.
1431 * Made the silc_server_command_pending_error_check to send
1432 the same command reply payload it received back to the
1433 original sender of the command. This way all arguments
1434 that was received by the server will be received by the
1435 client too. Affected file silcd/command.c.
1437 * Added the silc_idcache_add to return the created cache entry
1438 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1440 * Add global clients to expire if they are not on any channel.
1441 This is because normal server will never know if they signoff
1442 if they are not on any channel. The cache expiry will take
1443 case of these entries. This is done by normal servers only.
1444 The affected files are silcd/command_reply.c,
1445 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1447 * If server receives invalid ID notification for WHOIS or
1448 IDENTIFY and the ID exists in the lists, it is removed.
1449 Affected file silcd/command_reply.c.
1451 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1452 in client then client entry that it matches is searched and
1453 the nickname is printed on the screen for user. Affected
1454 file irssi/src/silc/core/client_ops.c.
1456 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Use cache entry expire time in the LIST command reply to
1459 purge old entries from the cache after the LIST command
1460 reply has been received. This way we don't have non-existent
1461 entries in the cache for too long. Affected file is
1462 silcd/command_reply.c.
1464 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * If we are normal server, and we've not resolved client info
1467 in WHOIS or IDENTIFY from router, and it is global client,
1468 we'll check whether it is on some channel. If it is not
1469 then we cannot be sure about its validity and will resolve it
1470 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1471 file silcd/command.c.
1473 * Search channel by name (if possible) rather than by ID
1474 in IDENTIFY command's command reply. Affected file is
1475 silcd/command_reply.c.
1477 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1480 Updated specs and implemented it. Affected file silcd/command.c,
1481 silcd/packet_send.c and silcd/packet_receive.c.
1483 * Implemented the <founder auth> payload handling in the JOIN
1484 command. If provided all conditions for channel joining
1485 except requirement to provide correct passphrase can be
1486 overrided by the channel founder. Updated the protocol specs.
1487 Affected file silcd/command.c.
1489 Added support for founder auth in JOIN command in client
1490 library. Fixed the parsing of the JOIN command now to support
1491 all options as they should be. The affected file is
1492 lib/silcclient/command.c.
1494 * Optimized the WHOIS and IDENTIFY commands to send the request
1495 to router only if it includes nicknames or other names. If
1496 they include only IDs then check the local cache first before
1497 routing. Affected file is silcd/command.c.
1499 * Added channels topic announcements. Affected file is
1500 silcd/packet_receive.c and silcd/server.c.
1502 * Fixed the silc_server_send_notify_topic_set to really destine
1503 the packet to channel. Affected file silcd/packet_send.c.
1505 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1506 library. Affected file lib/silcclient/client_notify.c.
1508 * Added UMODE announcements. Affected file silcd/server.c.
1510 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * Memory leak fixes in:
1514 lib/silcutil/silcsockconn.c
1515 lib/silcske/silcske.c
1516 lib/silcske/groups.c
1518 lib/silccrypt/silcpkcs.c
1519 lib/silccore/silccommand.c
1520 lib/silccore/silcidcache.c
1525 * ROBOdoc documented the lib/silcske/groups.h file and a
1526 bit changed the interface for better.
1528 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1530 * Update the client entry context in the ID cache after
1531 nick change. Affected file lib/silcclient/command.c.
1532 Fixes the CUMODE command when regaining founder privileges,
1533 and a little WHOIS problem.
1535 * Fixed silc_net_gethostbyname to correctly call the
1536 inet_ntop. Affected file lib/silcutil/silcnet.c.
1538 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1540 * Added IPv6 support checking to the configure.in.pre, added
1541 also --enable-ipv6 option to override the check. Affected
1542 file configure.in.pre.
1544 * The silc_thread_create now calls the start function
1545 directly if threads support is not compiled in. Removes
1546 ugly #ifdef's from generic code. Affected files are
1547 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1549 * Added silc_net_gethostby[name/addr]_async to asynchronously
1550 resolve. Affected files are lib/silcutil/silcnet.[ch].
1552 * Added support for rendering IPv6 based server, client and
1553 channel IDs. Affected file lib/silcutil/silcutil.c.
1555 * Added support for creating IPv6 based server IDs. Affected
1556 file is silcd/serverid.c.
1558 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1560 * Added silc_net_gethostby[addr/name] into the
1561 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1562 routines. Added silc_net_is_ip[4/6]. Affected file is
1563 lib/silcutil/unix/silcunixnet.c. All routines that take
1564 address as argument now supports both IPv4 and IPv6 addresses.
1566 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1568 * Fixed LIST command reply sending in server. Affected file
1571 * Server now sends the kicker's client ID in the KICK notify
1572 to the kicked client. Affected file silcd/command.c.
1574 * The client library now parses the kickers client ID and
1575 UI displays it. Affected files lib/silcclient/client_notify.c
1576 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1578 * Made all payload parsing function prototypes consistent.
1579 They all take now const unsigned char * and uint32 pair as
1580 the payload data instead of SilcBuffer. Changes all around
1581 the source tree. Other unsigned char* -> const unsigned char*
1582 changes around the tree as well.
1584 * Optimized SFTP client and server packet sending not to
1585 allocate new buffer for each packet but to recycle the
1586 first allocated buffer. Affected files are
1587 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1589 * Optimized the SFTP client to use SilcList instead of
1590 SilcDList for requests, because it is faster. Affected file
1591 is lib/silcsftp/sftp_client.c.
1593 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1594 into lib/silccore/silcid.[ch].
1596 Renamed silcpayload.[ch] into silcargument.[ch].
1598 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * If client entry is deleted with active key agreement
1601 session, abort the session.
1603 The silc_client_abort_key_agreement now calls the completion
1604 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1606 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1609 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Don't use __restrict in older GCC's. Affected file is
1612 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1614 * silc_net_localhost now attempts to reverse lookup the
1615 IP/hostname. Affected file lib/silcutil/silcnet.c.
1617 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1618 command. It can be used to gain founder privileges at
1619 the same time when joining the channel.
1621 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1622 kicker's client ID as well. Updated protocol specs.
1624 Defined that the server must send SILC_COMMAND_IDENTIFY
1625 command reply with error status to client who sent
1626 private message with invalid client ID.
1628 Updated the protocol specification.
1630 * Added silc_server_send_command_reply to send any
1631 command reply. Affected file silcd/packet_send.[ch].
1633 * Added silc_id_payload_encode_data to encode ID payload
1634 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1636 * The server now send IDENTIFY command reply with error
1637 status if client ID in private message is invalid. Affected
1638 file silcd/packet_receive.c.
1640 * Save the server key file with server's IP address in
1641 the filename instead of hostname. The affected file is
1642 irssi/src/silc/core/client_ops.c.
1644 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1649 * Added libtool support for compiling shared objects in
1650 lib/silcsim. Affected file configure.in.pre and
1651 lib/silcsim/Makefile.am. Original patch by cras.
1653 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Pid file configuration, and server's config file fixes
1656 patch by toma. Updated CREDITS file.
1658 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * Fixed silc_client_channel_message to not try to decrypt
1661 the message twice if it resolved the destination client
1662 information. This could cause of dropping one channel
1663 message. Affected file lib/silcclient/client_channel.c.
1665 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1668 lib/silcclient/client.c. This function is used when the SILC
1669 Client is run under some other scheduler, or event loop or
1670 main loop. On GUI applications, for example this may be
1671 desired to used to run the client under the GUI application's
1672 main loop. Typically the GUI application would register an
1673 idle task that calls this function multiple times in a second
1674 to quickly process the SILC specific data.
1676 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1678 * Fixed silc_server_drop() for dropping the supplementary
1679 groups as well, this could cause a security hole on some
1682 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1684 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1687 * Write PID file after dropping privileges. Added -F option
1688 to run server on foreground. A patch by debolaz.
1689 Affected files silcd/server.c, silcd/silcd.c.
1691 * Fixed MOTD to return the MOTD file server name. Affected
1692 file silcd/command.c.
1694 * Added INFO command reply handling to the Irssi SILC Client.
1695 Affected file irssi/src/silc/core/client_ops.c.
1697 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Fixed the silc_idcache_list_* routines to really support
1700 the dynamic list. Fixes a crash. Affected file is
1701 lib/silccore/silcidcache.c.
1703 * Fixed the LIST command reply to really call LIST command's
1704 pending callbacks. Affected file silcd/command_reply.c.
1706 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Update conn->local_entry->nickname after giving NICK
1709 command. Affected file lib/silcclient/command.c.
1711 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1713 * Added the [pid] option to the silcd configuration file
1715 Affected files: serverconfig.[ch] and silcd.c
1717 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * Save fingerprint in WHOIS command reply in server.
1720 Affected file silcd/command_reply.c.
1722 * Fixed NICK commands pending callback registration.
1723 Affected file lib/silcclient/command.c.
1725 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1727 * Use ++server->cmd_ident when sending commands in server,
1728 instead of random number. Affected file silcd/command.c.
1730 * Fixed GETKEY command reply to call actually GETKEY pending
1731 command callbacks. Affected file silcd/command_reply.c.
1733 * A bit stricter check for nicknames. Check for same nickname
1734 in NICK command also. Affected file silcd/command.c.
1736 * Do not call INFO command everytime client ID changes, only
1737 during first connecting. Affected file lib/silcclient/client.c.
1739 * Set the new nickname only after successful command reply for
1740 NICK command is returned by server. Affected file
1741 lib/silcclient/command.c.
1743 * Remove nicknames from nicklist during server_signoff notify.
1744 Should fix /NAMES bit more. The affected file is
1745 irssi/src/silc/core/silc-channels.c.
1747 * Added `fingerprint' field to the SilcIDListData in the
1748 silcd/idlist.h to hold the fingerprint of the client's
1751 Send the fingerprint of the client's public key in WHOIS
1754 Affected files silcd/command.c, and silcd/idlist.[ch].
1756 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1757 create fingerprint from given data.
1759 * Show the fingerprint of the client's public key in WHOIS.
1760 Affected files irssi/src/module-formats.[ch] and
1761 irssi/src/silc/core/client_ops.c.
1763 * Format the multiple same nicknames also during JOIN and
1764 NICK_CHANGE notifys. Affected file is
1765 lib/silcclient/client_notify.c.
1767 * Do not print error on screen for invalid private message
1768 payload since it can come if someone is sending private
1769 messages with wrong key. Affected file
1770 lib/silccore/silcprivate.c.
1772 * Fixed multiple concurrent /PING crash. Affected file
1773 lib/silcclient/command.c.
1775 * Changed the wrong ID encoding. All IP addresses must be
1776 in MSB first order in encoded format. They were encoded
1777 wrong and was in LSB format. Affected files are
1778 silcd/serverid.c, lib/silcutil/silcutil.c.
1780 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1782 * Call the `connect' client operation through the scheduler
1783 in case of error. Affected file lib/silcclient/client.c.
1785 * Call the `failure' client operation even if the error
1786 occurred locally during a protocol. Affected file is
1787 lib/silcclient/protocol.c.
1789 * Added support of sending LIST command to router from normal
1790 server. This way normal server can get list of all channels
1791 in the network too. Fixed the channel list sending in the
1792 server too. Affected files are silcd/command.c, and
1793 silcd/command_reply.[ch].
1795 * Added silc_server_update_channels_by_server and
1796 silc_server_remove_channels_by_server. They are used during
1797 disconnection of primary router and in backup router protocol.
1798 Affected file silcd/server_util.[ch], silcd/server.c and
1799 silcd/server_backup.c.
1801 * Fixed channel adding to global list in IDENTIFY command
1802 reply in server. Affected file silcd/command_reply.c.
1804 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * If the incoming packet type is REKEY or REKEY_DONE process
1807 that packet always synchronously. Fixes yet another MAC
1808 failed error on slow (dialup) connections. Affected file
1809 lib/silcclient/client.c and silcd/server.c.
1811 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Call check_version SKE callback for initiator too. Affected
1814 file lib/silcske/silcske.c.
1816 * Implemented fix for security hole found in the SKE that was
1817 fixed in the specification few days back; the initiator's
1818 public key is now added to the HASH value computation.
1819 Added backwards support for the old way of doing it too, for
1820 old clients and old servers. Affected file is
1821 lib/silcske/silcske.c.
1823 * Enabled mutual authentication by default in SKE. If initiator
1824 is not providing mutual authentication the responder will
1825 force it. This will provide the proof of posession of the
1826 private key for responder. The affected files are
1827 lib/silcclient/protocol.c and silcd/protocol.c.
1829 * Do not cache anymore the server's public key during SKE.
1830 We do mutual authentication so the proof of posession of
1831 private key is done, and if the server is authenticated in
1832 conn auth protocol with public key we must have the public
1833 key already. Affected file silcd/protocol.c.
1835 * Added new global debug variable: silc_debug_hexdump. If
1836 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1837 file lib/silcutil/silclog.[ch].
1839 * Fixed compilation warning due to char * -> const char *.
1840 Affected files lib/silcutil/silcnet.h, and
1841 lib/silccore/silcauth.[ch].
1843 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Fixed CMODE command when new channel key was created. If
1846 the creation failed the old key was removed. Next time giving
1847 same command would crash the server since the old key was
1848 freed already. Affected file silcd/command.c.
1850 * Fixed the silc_server_announce_get_channels to not crash
1851 on reconnect. Affected file silcd/server.c.
1853 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1855 * Added silc_log_set_debug_string function to set a regex
1856 string to match for debug output. Only the function names,
1857 or filenames matching the given debug string is actually
1858 printed. This way it is possible to filter out those debug
1859 strings that user is not interested in.
1861 Fixed a bug in silc_string_regexify.
1863 Affected files lib/silcutil/silclog.[ch], and
1864 lib/silcutil/unix/silcunixutil.c.
1866 * Changed the -d options in both server and Irssi SILC client
1867 to take the debug string as argument. Affected files
1868 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1870 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Added silc_hash_babbleprint to create a Bubble Babble
1873 Encoded fingerprint. The encoding is developed by Antti
1874 Huima (draft-huima-babble-01.txt), and it creates human
1875 readable strings out of binary data. Affected file
1876 lib/silccrypt/silchash.[ch].
1878 * Print the babble print now in addition of fingerprint as well
1879 in Irssi SILC client. Affected files are
1880 irssi/src/fe-common/silc/module-formats.[ch],
1881 irssi/src/fe-common/silc/core/client_ops.c.
1883 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * Fixed a security problem found in SKE. The initiator's
1886 public key too is now added to the HASH hash value creation
1887 which is signed by the responder to create the SIGN value.
1888 This will prevent anyone in the middle to lie to the responder
1889 about the initiator's public key. If this is done now, the
1890 man in the middle will get caught. Updated the protocol
1893 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Better installation directory handling. Configure module
1896 paths and other paths automatically to example_silc* files
1897 in doc/. A patch by toma.
1899 * Fixed compiler warning from MPI library, and from SILC RNG.
1902 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1903 It can be configured with ./configure. A patch by toma.
1905 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Find correct make to use in prepare-clean. A patch by
1908 toma. Affected file prepare-clean.
1910 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1912 * Added irssi variables use_auto_addr, auto_bind_ip,
1913 auto_bind_port and auto_public_ip.
1915 * Changed the interface for silc_client_send_key_agreement
1916 in lib/silcclient/silcapi.h
1920 irssi/src/silc/core/silc-core.c
1922 lib/silcclient/silcapi.h
1923 irssi/src/silc/core/silc-channels.c
1924 lib/silcclient/client_keyagr.c
1927 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Added silc_pkcs_public_key_compare to compare two
1930 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1932 * Check that the client who set the founder mode on the
1933 channel is the same client that is giving the founder
1934 mode to itself. It is done by comparing the saved public
1935 key (it is saved even in the authentication is passphrase).
1936 Affected file silcd/command.c.
1938 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Do not process packet for disconnected socket connection.
1941 Affected file lib/silccore/silcpacket.c.
1943 * Process the DISCONNECT packet through scheduler in the
1944 client library. Affected file lib/silcclient/client.c.
1946 * Fixed the silc_client_packet_parse to not to increase
1947 the packet sequence number if the conn->sock and the
1948 current socket connection is not same. This can happen
1949 for example during key agreement when the conn includes
1950 multiple socket connections (listeners). Affected file
1951 lib/silcclient/client.c.
1953 * The sender of the file transfer request now provides also
1954 the pointer (listener) for the key exchange protocol. If
1955 the listener cannot be created then it sends empty key
1956 agreement and lets the receiver provide the listener.
1958 Added `local_ip' and `local_port' arguments to the
1959 silc_client_file_send. If they are provided they are used,
1960 if not then it will attempt to find local IP address, if
1961 not found or bind fails then the remote client will provide
1964 Affected files are lib/silcclient/client_ftp.c and
1965 lib/silcclient/silcapi.h.
1967 * Extended the FILE SEND command to support defining the
1968 local IP and port for key exchange listener. They are
1969 optional. Affected file irssi/src/silc/core/silc-servers.c.
1971 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Defined to WHOIS command reply the sending of fingerprint
1974 of the client's public key (if the proof of posession of the
1975 corresponding private key is verified by the server).
1976 Updated to the protocol specification.
1978 * Added support of receiving the client's public key's
1979 fingerprint in command reply in client library. Affected
1980 file is lib/silcclient/command_reply.c, and
1981 lib/silcclient/idlist.[ch].
1983 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Do not send over 128 chars long nickname to the server
1986 in NICK command. Affected file lib/silcclient/command.c.
1988 * Do not send over 256 chars long channel names to the server
1989 in JOIN command. Affected file lib/silcclient/command.c.
1991 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Assure that silc_server_close_connection cannot be called
1994 twice for same socket context. Affected file is
1997 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Send error message to application if opening file for
2000 writing during file transfer fails. Affected file is
2001 lib/silcclient/client_ftp.c.
2003 Remove all file transfer sessions for a client that we're
2004 removing from ID cache.
2006 Affected file is lib/silcclient/client_ftp.c.
2008 * Fixed silc_net_addr2bin to return correct address. Affected
2009 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2011 * Fixed file transfer session removing on signoff notify.
2012 Affected file irssi/src/silc/core/silc-servers.c.
2014 * Added the SilcClientFileError to be returned in the monitor
2015 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2016 Affected file lib/silcclient/silcapi.h.
2018 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * Fixed a crash in silc_client_ftp_free_sessions and
2021 silc_client_ftp_session_free_client. Affected file
2022 lib/silcclient/client_ftp.c.
2024 * Added `disabled' field in the SilcChannelEntry in the server
2025 to indicate if the server entry is disabled. Affected file
2026 silcd/idlist.h, silcd/command[_reply].c.
2028 * SILC server adds now /var/run/silcd.pid everytime it is
2029 started. Affected file silcd/silcd.c.
2031 * Added silc_server_packet_send_clients to send a packet to
2032 the provided table of client entries. Affected file
2033 silcd/packet_send.[ch].
2035 * Fixed a crash in client resolving in client_prvmsg.c in
2036 client library. Affected file lib/silcclient/client_prvmsg.c.
2038 * Do not actually remove the client directly from ID cache
2039 during SERVER_SIGNOFF, but invalidate it. This way we
2040 preserve the WHOWAS info for the client. Affected file
2041 silcd/server_util.c.
2043 * Fixed SERVER_SIGNOFF notify handling in the server. The
2044 server is now able to process incoming SERVER_SIGNOFF notify
2045 for a server that it doesn't even know about. It will remove
2046 the clients provided in the notify. Affected file
2047 silcd/packet_receive.c.
2049 * Check for partial packet in data queue after every packet that
2050 was found from the queue. Return and wait for more data if
2051 there is partial data in queue. Affected file is
2052 lib/silccore/silcpacket.c.
2054 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Added SilcClietFileError enum to indicate error in
2057 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2058 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2059 Affected files lib/silcclient/silcapi.h and
2060 lib/silcclient/client_ftp.c.
2062 * Check that newsize in silc_buffer_realloc is larger than
2063 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2065 * Added better monitor of file transfers. It now monitors
2066 key agreement protocol during the file transfer too. Added
2067 error reporting too. Affected files
2068 irssi/src/silc/core/silc-servers.c,
2069 irssi/src/fe-common/silc/module-formats.[ch].
2071 * Wrote a help file for FILE command.
2073 * Added silc_rng_global_get_byte_fast to get not-so-secure
2074 random data as fast as possible. Random data is read from
2075 /dev/urandom if available and from the SILC RNG if not
2076 available. It is used in padding generation. Affected file
2077 lib/silccrypt/silcrng.[ch].
2079 * All packets in client library are now processed synchronously.
2080 Optimized packet processing a lot. Affected file
2081 lib/silcclient/client.c.
2083 * All server connection packets are processing synchronously
2084 now in server, to optimize packet processing. Affected file
2087 * Include files are installed now only in Toolkit distribution
2088 if make install is given. Affected files: all Makefile.am's.
2090 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2092 * Assure that silc_client_notify_by_server_resolve does not
2093 resolve the client information multiple times. If it cannot
2094 be found by the first it cannot be found at all. Affected
2095 file lib/silcclient/client_notify.c.
2097 * Fixed WHOWAS command reply calling. Affected file
2098 lib/silcclient/command_reply.c.
2100 * Removed all references to silc_idlist_get_client from the
2101 Irssi SILC client since that call is internal call used by
2102 the library. The Irssi SILC client will use now client
2103 retrieval functions found in silcapi.h.
2105 * Fixed a bug in resolving nickname info before sending
2106 private message. It used freed memory. Affected file
2107 irssi/src/silc/core/silc-servers.c.
2109 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Assure my_channels statistics cannot go negative in server.
2112 Affected files silcd/server.c, silcd/server_util.c.
2114 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2118 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Win32 Toolkit changes. Affected files
2121 win32/silc.dsw, win32/libsilc/libsilc.def,
2122 win32/libsilcclient/libsilc.def,
2123 lib/silcutil/silcutil.c, and
2124 lib/sftp/sftp_fs_memory.c.
2126 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Added silc_net_localip to return local host's IP address.
2129 Affected file lib/silcutil/silcnet.[ch].
2131 * If key exchange or rekey protocol is active for a connection
2132 parse all packets syncronously since there might be packets
2133 in packet queue that we are not able to process without first
2134 processing packets before them. Affected file silcd/server,
2135 lib/silcclient/client.c.
2137 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2138 whether library should continue processing the packet.
2139 Affected file lib/silccore/silcpacket.h.

2170 lib/silcutil/silcutil.[ch].
2172 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Resolve the client info when received private message or
2175 channel message for a client which nickname we don't know.
2176 Affected files lib/silcclient/client_prvmsg.c and
2177 lib/silcclient/client_channel.c.
2179 * Do not crash in /KEY if client is not connected. Affected
2180 file irssi/src/silc/core/silc-channels.c.
2182 * Added SilcClientStatus field to the SilcClientEntry in the
2183 lib/silcclient/idlist.h.
2185 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2186 is incomplete and is being resolved, it won't be resolved
2189 Make sure also that USERS command reply does not resolve
2190 twice information. Affected file is
2191 lib/silcclient/command_reply.c.
2193 Make sure that silc_client_get_clients_by_list does not
2194 resolve twice same information.
2196 * Check for valid client->id in the silc_server_free_client_data.
2197 Affected file silcd/server.c.
2199 * Fixed /GETKEY nick@server not to crash if the server entry
2200 is not found. Affected file lib/silcclient/command.c.
2202 * Fixed the silc_server_check_cmode_rights to check the
2203 requested modes correctly. Affected file silcd/command.c.
2205 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Better checks for non-printable chars in nick added.
2208 Affected file silcd/command.c.
2210 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Call the silc_server_udpate_servers_by_server in the
2213 primary router that comes back online in the backup resuming
2214 protocol. Otherwise it routes packets wrong. Affected file
2215 silcd/server_util.[ch], silcd/server_backup.c.
2217 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2220 lib/silcutil/silcbuffmt.[ch].
2222 * Redefined the SILC packet header to include the padding
2223 length. Affected file lib/silccore/silcpacket.[ch].
2225 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2226 length for maximum padding up to 128 bytes). Affected
2227 file lib/silccore/silcpacket.h.
2229 * Removed all backwards support for old 0.5.x MAC thingies.
2230 The SILC packet header change makes it impossible to be
2231 backwards compatible.
2233 * Send the ENDING packet with timeout in the backup resuming
2234 protocol. This is to assure that all routers has connected
2235 to the primary router. Affected file silcd/server_backup.c.
2237 * Changed the RNG to take the first IV from random data. It
2238 used to take it from zero actually. Changed the RNG also
2239 to use /dev/urandom during session. /dev/random is used
2240 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2242 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Changed the SILC packet header to have the first two bytes
2245 (the packet length) encrypted. Affected files aroung the
2246 code tree, lib/silccore/silcpacket.[ch]. Removed the
2247 SilcPacketCheckDecrypt callback. It is not needed anymore
2248 since the silc_packet_receive_process will determine now
2249 whether the packet is normal or special.
2251 * Implemented the unidirectional MAC keys. Affected files
2252 lib/silcske/silcske.c, silcd/protocol.c and
2253 lib/silcclient/protocol.c.
2255 * Implemented the packet sequence number to the MAC computation.
2256 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2257 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2258 lib/silcclient/protocol.c.
2260 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Allow backup router to announce servers. All servers
2263 announced by backup router are added to the global list
2264 automatically. Update hte server's socket to our primary
2265 router also when backup router announces a server.
2266 Affected file silcd/packet_receive.c.
2268 * Do not update the client->router in the function
2269 silc_server_udpate_clients_by_server if the client is on
2270 global list. We might fail to find any specific server
2271 for locally connected clients and local cell clients. They
2272 should still use the `from' and not `to' as client->router.
2273 This fixes backup router resuming protocol. Affected file
2274 silcd/server_util.c.
2276 * Decrease channel statistics count only if the channel
2277 deletion worked. Affected files are silcd/server.c and
2278 silcd/server_util.c.
2280 * Added silc_server_update_servers_by_server to update origin
2281 of all server entries. Used during backup router protocol.
2282 Affected files silcd/server_util.[ch], silcd/server.c. and
2283 silcd/backup_router.c.
2285 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2286 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2287 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2288 lib/silccrypt/silchmac.c.
2290 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Assure that router cannot reroute the same channel message
2293 to the sender. Affected file silcd/packet_receive.c.
2295 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Made better checks that the channel message is not sent
2298 to the router it came from. Affected file is
2299 silcd/packet_send.c. Fixed memory leak too.
2301 * Announce informations for incoming router connection, but
2302 only after checking if it is replaced by backup router.
2303 Affected file silcd/packet_receive.c.
2305 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Fixed the backup resuming protocol to work in multiple
2308 router environment. Affected file silcd/server_backup.c.
2310 * Route packet only to one router in the function
2311 silc_server_packet_send_to_channel. Affected file is
2312 silcd/packet_send.c.
2314 * Fixed silc_server_send_notify_dest to set the broadcast
2315 flag. Fixed the silc_server_send_notify_topic to actually
2316 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2317 Affected file silcd/packet_send.c.
2319 * Changed the SFTP Filesystem interface. Changed the
2320 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2321 the filesystem operation function. The SilcSFTPFilesystem
2322 is now a context that is allocated by all filesystem allocation
2323 functions and it already includes the operations structure
2324 and filesystem specific context. It is given as argument
2325 now to the silc_sftp_server_start. This made the interface
2326 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2327 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2329 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Changed the backup router adding and getting interfaces
2332 in the server. The router that will be replaced by the
2333 specified backup router is now sent as argument. Affected
2334 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2337 * Added silc_net_addr2bin_ne to return the binary form of
2338 the IP address in network byte order. Affected files
2339 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2341 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Check for existing server ID in silc_server_new_server
2344 and in silc_server_connect_to_router_final and remove the
2345 old entry if it exists. Affected file silcd/packet_receive.c,
2348 * Send the channel message always to only one router, either
2349 in upstream or downstream. Affected file is
2350 silcd/packet_send.c.
2352 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2354 * Wrote the definition of the backup resuming protocol to the
2355 protocol specification.
2357 * Removed one redundant channel key generation from normal
2358 server during joining procedure. Removed one redundant
2359 channel key sending from server to router during joining
2360 procedure. Affected file silcd/command.c.
2362 * Made minor bugfixes to the backup router resuming protocol.
2363 Affected file silcd/server_backup.c, server.c.
2365 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Added --disable-asm configuration option. Affected files
2368 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2371 * Implemented the backup resuming protocol that is used to
2372 resume the primary router position in the cell after the
2373 primary router comes back online. Affected files
2374 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2375 and silcd/server_util.[ch].
2377 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Sleep two (2) seconds after sending QUIT command to server.
2380 Affected file lib/silcclient/command.c.
2382 * Assure that if outgoing data buffer is pending do not force
2383 send any data. Affected file silcd/packet_send.c.
2385 * Assure that if outgoing data buffer is pending do not force
2386 send any data. Affected file lib/silcclient/client.c.
2388 * Implemented the backup router support when the primary router
2389 goes down. The servers and routers can now use the backup
2390 router as new primary router without loosing connectivity.
2392 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2395 in the server to indicate disabled entry. All data read
2396 from the connection will be ignored and no data is sent
2397 for entry that is disabled. Affected files are
2398 silcd/idlist.h, silcd/server.c.
2400 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Created SFTP client and server test programs in the
2403 lib/silcsftp/tests directory.
2405 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Implemented memory filesystem (virtual filesystem) for
2408 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2411 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Implemented the SFTP (SSH File Transfer Protocol) to the
2414 lib/silcsftp. It includes SFTP client and SFTP server
2417 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Moved lib/silccore/silcprotocol.[ch] to the
2420 lib/silcutil library.
2422 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2423 take variable argument list pointer as argument. Affected
2424 file lib/silcutil/silcbuffmt.[ch].
2426 * Added silc_buffer_set function that is used to set data
2427 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2428 Affected file lib/silcutil/silcbuffer.h.
2430 * Changed various routines in the core library to use the new
2431 silc_buffer_set instead of allocating new buffer only for
2434 * Added 64-bit value formatting and unformatting support to the
2435 silc_buffer_[un]format routines. Affected file is
2436 lib/silcutil/silcbuffmt.[ch].
2438 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2439 to includes/bitmove.h.
2441 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2443 * Fixed channel user mode saving in client library. Affected
2444 file lib/silcclient/command[_reply].c.
2446 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Defined the file transfer to the SILC Protocol. Added
2449 new packet type SILC_PACKET_FTP and defined File Transfer
2450 Payload. The mandatory file transfer protocol is SFTP
2451 (SSH File Transfer Protocol). Affected file in addition
2452 of the internet draft is lib/silccore/silcpacket.h.
2454 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2455 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2456 is used as part of backup router protocol when the primary
2457 router of the cell is back online and wishes to resume
2458 the position as primary router.
2460 * Redefined the MAC generation keys in the protocol. The
2461 same key is not used anymore in both direction. Both
2462 direction will now use different keys for sending and
2463 receiving. This fixes a potential security flaw. This
2464 change causes incompatibilities in the protocol.
2466 * Redefined also the MAC computation from the packet.
2467 An packet sequence number is now added to the MAC
2468 computation. This prevents possible replay attacks against
2469 the protocol. This change too causes incompatibilities
2472 Added `sequence' field to the SilcPacketContext to hold
2473 the current sequence number for the packet.
2475 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Added `created' field to the SilcIDListData in the file
2478 silcd/idlist.h to indicate the time when the entry was
2481 * Added `created' field to the SilcChannelEntry too. Affected
2482 file silcd/idlist.h.
2484 * Added `creation_time' aguments to all the announcement functions
2485 in the server. If it is provided then only the entries that
2486 was created after the provided time frame are actually
2487 announced. Affected file silcd/server.[ch].
2489 * The protocol says that the Channel ID's IP address must be
2490 based on the router's IP address. Added check for this in
2491 the silc_server_new_channel when processing incoming New Channel
2492 Payload. Affected file silcd/packet_receive.c.
2494 * Print out the correct version with --version in SILC client.
2495 Affected file irssi/src/silc/core/silc-core.c.
2497 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Fixed WHOWAS command to check for completnes of the client
2500 entry always, not just when the command is coming from client.
2501 Affected file silcd/command.c.
2503 * Added new function silc_server_packet_queue_purge to purge the
2504 outgoing data queue to the network. After the function returns
2505 it is guaranteed that the outgoing packet queue is empty.
2506 Affected file silcd/packet_send.[ch].
2508 * Purge the outgoing packet queue in the rekey protocol's final
2509 callback to assure that all rekey packets go to the network
2510 before quitting the protocol. Affected file silcd/server.c.
2512 * Added silc_client_packet_queue_parse as similar function as
2513 in server to the client library. The affected file is
2514 lib/silcclient/client.c.
2516 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2518 * Splitted silcd/server.c and created silcd/server_util.[ch]
2519 for utility functions.
2521 * Added new socket flag SILC_SF_DISABLED to indicate that the
2522 connection is open but nothing can be sent to or received from
2523 the connection. Affected file lib/silcutil/silsockconn.[ch].
2524 The checking for disabled socket is checked in the low level
2525 silc_socket_write and silc_socket_read functions.
2527 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Allow only nicknames and channel names that fits into the
2530 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2532 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * When processing JOIN command reply in server check that if
2535 the channel exists in our global list we'll move it the local
2536 list. Affected file silcd/command_reply.c.
2538 * Fixed the check whether client is joined on the channel already
2539 in JOIN command. Affected file lib/silcclient/command.c.
2541 * Fixed the JOIN command reply to check whether the channel
2542 already exists. Affected file lib/silcclient/command_reply.c.
2544 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Added silc_ske_status_string to map the SKE error numbers
2547 to readable strings. The affected files are
2548 lib/silcske/silcske[_status].[ch].
2550 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Do not show the private channels on the WHOIS channel list
2553 as it is not allowed by the protocol. The affected file is
2556 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Assure that the packet length digged from the actual packet
2559 is something sensible in the silc_packet_decrypt_rest_special
2560 in lib/silccrypt/silcpacket.c.
2562 * Free and NULL the allocated pointer in silc_hmac_alloc if
2563 the HMAC allocation fails. The affected file is
2564 lib/silccrypt/silchmac.c.
2566 * Print the selected security properties to the log files in
2567 the server. Affected file silcd/protocol.c.
2569 * Add SKE's reference counter even if calling the completion
2570 callback manually. Otherwise it goes negative, although it
2571 does not cause any problems. The affected file is
2572 lib/silcske/silcske.c.
2574 * Remove the client entry with short timeout after giving the
2575 KILL command. Affected file lib/silcclient/command.c.
2577 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2578 case all found clients are already disconnected (WHOWAS would
2579 found them) in the server. Affected file silcd/command.c.
2581 * Update the last_receive (time of last data received) to be
2582 updated only when received private or channel message so that
2583 the idle time showed in WHOIS makes more sense.
2585 * Added boolean field `valid' in to the SilcClientEntry in the
2586 client library to indicate whether the entry is valid or not.
2587 This fixes the nickname change bug on channel when changing
2588 the nickname to be same than the old (like nick to Nick) the
2589 nickname formatter doesn't set the new nick anymore to Nick@host.
2590 Affected file lib/silcclient/idlist.[ch].
2592 * Now actually fixed the nickname changing on disconnection.
2593 Added new function silc_change_nick to the Irssi SILC Client.
2594 Affected file irssi/src/silc/core/client_ops.c,
2595 irssi/src/silc/core/silc-nicklist.[ch].
2597 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Check that the public key exists in the GETKEY command before
2600 trying to encode it. Affected file silcd/command.c.
2602 * Print some notifications on received public keys with GETKEY
2603 command in the Irssi SILC Client. Affected files are
2604 irssi/src/fe-common/silc/module-formats.[ch],
2605 irssi/src/silc/core/client_ops.c.
2607 * Use IDENTIFY command to resolve the server information in the
2608 GETKEY command instead of INFO command. Affected file
2609 lib/silcclient/command.c.
2611 * All command reply functions in the client library now calls
2612 the pending command reply callbacks even if an error has
2613 occurred. The server has done this a long time and now it was
2614 time to move the client library to this as well. Now all
2615 errors can be delivered back to the pending command reply
2616 callbacks if necessary. Affected files are
2617 lib/silcclient/command[_reply].[ch].
2619 * Change the nickname on disconnection back to the username
2620 because in reconnect the server will enforce it to it anyway.
2621 Affected file irssi/src/silc/core/silc-servers.c.
2623 * Fixed a config file parsing bug in the Irssi SILC client.
2624 Affected file irssi/src/silc/core/clientconfig.c.
2626 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * When printing the channel mode on JOIN, verify that the
2629 channel key and channel's HMAC are valid. Affected file
2630 irssi/src/silc/core/client_ops.c.
2632 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2635 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2636 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2638 * Removed channel key rekey task deleting from the function
2639 silc_server_save_channel_key. Affected file silcd/server.c.
2640 Added explicit timeout task context instead that is used to
2641 delete the task if we are registering a new task before the
2642 new task has elapsed.
2644 * When channel key rekey occurs the client library now saves
2645 the old channel key for a short period of time (10 seconds) and
2646 is able to use it in case some is still sending channel
2647 messages encrypted with the old key after the rekey. Affected
2648 file lib/silcclient/[idlist.h|client_channel.c].
2650 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Added check to the silc_server_new_id_real to not accept
2653 new ID if it is the sender's own ID. Affected file is
2654 silcd/packet_receive.c.
2656 * Assure that we do not announce ourself or the one we've
2657 sending our announcements when we're router and are announcing
2658 servers to our primary router. Affected file silcd/server.c.
2660 * Fixed silc_server_command_identify_check_client to assemble
2661 correct WHOIS packet. It send corrupted WHOIS packet and
2662 caused problem with router to router connections. Affected
2663 file silcd/command.c.
2665 Fixed also silc_server_command_whois_check the same way
2666 as for the IDENTIFY command.
2668 * Added new SilcIDListStatus to the server in the SilcIDListData
2669 structure. The status now includes the current status of
2670 the entry (like registered, resolved etc.). Affected file
2671 silcd/idlist.[ch]. Defined a bunch of different status types
2672 as well. This replaced the old boolean registered field as well.
2674 Added resolve_cmd_ident field to the SilcClientEntry structure
2675 too so that if the entry is for example being resolved so
2676 another command may attach to the same pending command reply
2677 without requiring to resolve the same entry again. This concept
2678 should optimize the WHOIS and the IDENTIFY resolving under
2679 heavy load by taking away unnecessary resolving for entries
2680 that are being resolved already.
2682 Added support for adding multiple pending commands for one
2683 command idenfier. Affected file silcd/command[_reply].[ch].
2685 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2686 before deleting the data. Otherwise the hash table will have
2687 freed data in comparison functions. Affected file is
2688 silcd/command_reply.c.
2690 * Fixed silc_idlist_replace_client_id to add the new entry to
2691 the cache with NULL nickname. Otherwise there will be invalid
2692 memory as the nickname after the nickname is freed. Affected
2693 file silcd/packet_receive.c.
2695 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2696 saved into wrong slots because the previous number of entries
2697 was not taken into account. Affected file silcd/idlist.c.
2698 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2700 * If we are router and we receive JOIN notify to a channel that
2701 does not have any users then notified client is marked as the
2702 channel founder, as it is it. The affected file is
2703 silcd/packet_receive.c
2705 * Added to the extended hash table API's table_del_*ext functions
2706 the destructor as argument too, so that the caller can decide
2707 which destructor to use or whether to use destructor at all.
2708 Affected file lib/silcutil/silchashtable.[ch].
2710 * Fixed ID Cache purging. It actually deleted the entries from
2711 the hash table after the data was freed. The hash table ended
2712 up comparing freed memory. The affected file is
2713 lib/silccore/silcidcache.c.
2715 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Fixed Irssi SILC client's KILL command's HELP syntax.
2719 * The USERS command now resolves the detailed user information
2720 if the userinfo field is missing. Affected file is
2721 lib/silcclient/command_reply.c.
2723 * Do not print error in silc_file_read if the read file does
2724 not exist. Just silently return NULL. Affected file is
2725 lib/silcutil/silcutil.c.
2727 * Fixed the silc_log_output to not wine about NULL filename
2728 and to not create some bogus " " filename. Affected file is
2729 lib/silcutil/silclog.c.
2731 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Fixed various printing bugs on the user interface in the
2734 Irssi SILC Client. Minor changes that were forgotten from
2737 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2739 * Fixed the configure.in.pre and the compilation and distribution
2740 environment to support the new autoconf 2.52. That version is
2741 now required to compile the CVS trunk.
2743 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2746 to generally parse user@fqdn format strings. Affected file
2747 lib/silcutil/silcutil.c.
2749 * Added nickname_format and nickname_force_format fields to the
2750 SilcClientParams structure. The first one defines the format
2751 for the nicknames that the library will enforce if the receives
2752 multiple same nicknames. The second one is boolean value and
2753 can be used to force the library to always enforce the format
2754 to the nicknames regardles whether there are multiple nicknames
2755 or not. This configurable formatting was employed to flexibly
2756 support accessing multiple nicknames from the user interface.
2757 The userinterface can now set the nicknames to what ever format
2758 they prefer. Affected file lib/silcclient/silcapi.h.
2760 Added function silc_client_nickname_format to the file
2761 lib/silcclient/idlist.c. It performs the nickname formatting.
2763 Added new field `hostname´ to the SilcClientEntry context.
2764 It holds the hostname of the client. Affected file is
2765 lib/silcclient/idlist.h.
2767 * Irssi SILC Client sets the nicknames in nick@hostn format.
2768 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2769 irssi/src/silc/core/silc-core.c.
2771 The WHOIS printing now also shows both the real nickname and
2772 the formatted nickname so that user knows how to access the
2773 user if there are multiple same nicknames cached. Affected
2774 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2775 printing formatting too to take the hostname now as a separate
2776 argument. The Affected file is
2777 irssi/src/fe-common/silc/modules-formats.[ch].
2779 * Changed the silc_client_get_clients_local to accept the formatted
2780 nickname as argument. It accepts the real nickname too but the
2781 formatted nickname can be used to find the true entry from
2782 multiple entries. Affected file lib/silcclient/silcapi.h and
2783 lib/silcclient/idlist.c.
2785 * Added nickname_format_parse field to the SilcClientParams.
2786 It is a callback function provided by the application to parse
2787 the nickname out of the formatted nickname string. The library
2788 calls it to get the nickname from the formatted string. Since
2789 the application generally knows better the format of the nickname
2790 string it parses it instead of the library, even though library
2791 encodes the formatted string. If the callback function is not
2792 provided then the library will use the string as is. The
2793 affected file is lib/silcclient/silcapi.h.
2795 * All the nickname strings passed to the client library in
2796 commands are now expected to be formatted nickname strings.
2797 If the command does not support the formatted nickname string
2798 it will assume that the sent string is the actual nickname.
2799 Affected file lib/silcclient/command.c.
2801 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Added public key authentication support to OPER and SILCOPER
2804 commands in the client library. Affected file is
2805 lib/silcclient/command.c.
2807 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Changed the get_auth_methdod client operation to be asynchronous.
2810 It can be async if the application resolves the authentication
2811 method from the server during the negotiation. Added new
2812 SilcGetAuthMeth completion callback that the application will
2813 call after resolving the authentication method.
2815 Added function silc_client_request_authentication_method that
2816 the application can use to resolve the authentication method
2817 from the server. Added also SilcConnectionAuthRequest callback
2818 that the library will call after the server has replied. The
2819 application can call this function if it does not know the
2820 current authentication method.
2822 Affected files are lib/silcclient/client.c and
2823 lib/silcclient/silcapi.h.
2825 * The Irssi SILC client now automatically resolves the authentication
2826 method incase any configuration information is not present (and
2827 currently there never is). The affected file is
2828 irssi/src/silc/core/client_ops.c.
2830 * Fixed public key authentication from the client library.
2831 Affected file lib/silcclient/protocol.c. Changed also the
2832 protocol specification about the public key authentication in
2833 the connection authentication protocol. The actual data to be
2834 signed is now computed with a hash function before signing.
2836 * Fixed the public key authentication from the server as well.
2837 Affected file silcd/protocol.c.
2839 * Removed the mlock()'s from the memory allocation routines.
2840 Affected file lib/silcutil/silcmemory.c. The ./configure does
2841 not check anymore for the mlock(). Affected file is
2844 * Fixed USERS command in server to allow the execution of the
2845 command for private and secret channels if the client sending
2846 the command is on the channel. Affected file silcd/command.c.
2848 * Fixed silc_client_get_clients_local to return the clients
2849 count correctly. It could return wrong value. Affected file
2850 lib/silcclient/idlist.c.
2852 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2855 types. The assembler optimizations seemed not to like 64-bit
2856 data types. The assmebler optimizations thus are now enabled
2857 also for BSD systems as opposed to only enable them for Linux.
2859 * Do not check for threads at all on BSD systems. Affected
2860 file configure.in.pre.
2862 * Removed -n and -h options from the Irssi SILC Client since
2863 they are not used in silc.
2865 * Fixed the prime generation to assure that the first digit
2866 of the generated random number is not zero since our conversion
2867 routines does not like number strings that starts with zero
2868 digit. If zero digit is seen the random number is regenerated.
2869 This caused some corrupted RSA keys when the zero first digit
2870 was met. Affected file lib/silcmath/silcprimegen.c.
2872 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Fixed WIN32 configuration in the ./configure script.
2875 Fixed to include xti.h on environments that has it.
2876 Patches by Carsten Ilchmann and andrew.
2878 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Changed the silc_id_create_client_id to be collision
2881 resistant. It is now assured that there cannot be created
2882 two same client ID's. I suspect that some weird bugs in
2883 the server were actually caused by duplicate Client IDs.
2884 Affected file silcd/serverid.[ch]. A router receiving
2885 new ID now also assures and informs the sending server
2886 if the ID caused collision.
2888 * Changed the silc_id_create_channel_id to also assure that
2889 there are no collisions.
2891 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Statement about ignoring the Mutual Authentication flag when
2894 performing rekey with PFS was a bit misleading. It is ignored
2895 if it was set in the initial negotiation, it cannot be even
2896 set in the rekey. Fixed in the ke-auth draft. Started the
2897 new versions of the protocol drafts in the doc/.
2899 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Fixed a bug in silc_client_command_identify_save when saving
2902 new channel information. The channel name was no duplicated
2903 and caused crash on exit. Affected file is
2904 lib/silcclient/command_reply.c.
2906 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Fixed the getkey command handling in the server. Send just
2909 empty OK reply to the sender if the key could not be fetched
2910 (but everything else was ok, like the key just was not available).
2911 Changed the public key parameter to optional in the protocol
2912 specs so that empty OK reply can be sent. Affected file
2915 Added a message to Irssi SILC client to tell to user if the
2916 server did not return a public key.
2918 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Fixed a channel key regeneration bug. It registered new
2921 timeout tasks exponentially until all system resources were
2922 used. Affected file silcd/server.c.
2924 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Added the SILC Document generator to the scripts/silcdoc.
2927 It can be used to generate the Toolkit Reference Manual out
2928 of the source tree. Internally it will also use the RoboDoc
2929 generator now imported in util/robodoc.
2931 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Added couple of return's in rekey protocol if error orccurred
2934 during the protocol. The execution must be terminated.
2935 Affected file silcd/protocol.c. Also, terminate the protocol
2936 always with timeout.
2938 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * The client's Client ID was created initally from the wrong
2941 nickname (it could have been in format nick@host) in the
2942 silc_server_new_client. Affected file silcd/packet_receive.c
2944 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Added some SILC_LOG_ERROR's to various error conditions
2947 if client could not be added to ID cache. Affected files
2948 silcd/packet_receive.c and silcd/server.c.
2950 * When client's sock->user_data is freed, NULL also the
2951 client->router and client->connection pointers. Added check
2952 for these pointers being NULL to various places around the
2953 code. Affected file silcd/server.c.
2955 * Added client->data.registered == TRUE checks to various
2956 places around the code to assure that unregistered client's
2957 are not handled when it is not allowed. Affected file
2960 * Added `bool registered' fields to all
2961 silc_idlist_[server|client]_get_* routines to indicate whether
2962 the fetched client needs to be registered or not. Affected
2963 file silcd/idlist.[ch].
2965 * Add your own entry as registered to the ID cache in the
2966 server. Affected file server.c.
2968 * Fixed a bug in silc_server_new_server. The SilcServer was
2969 set as the new server's context instead of SilcServerEntry.
2970 This naturally caused some weird bugs.
2972 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Do not delete the channel rekey task when adding it
2975 for in silc_server_create_channel_key.
2977 * Changed the silc_server_create_channel_key to return
2978 TRUE or FALSE to indicate the success of the channel key
2981 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Fixed MSVC++ project files and added missing files to
2984 Makefiles under win32/.
2986 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Do not add TCP_NODELAY flag if the operating system
2989 does not have it defined. Affected files are
2990 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2992 * Fixed buffer overflow from Irssi SILC Client. Affected
2993 file irssi/src/fe-common/core/themes.c.
2995 * Fixed double free in client library in the file
2996 lib/silcclient/client.c when disconnecting from server.
2998 * Applied double free patch from cras to Irssi SILC client.
2999 Affected files irssi/src/core/[modules/expandos].c
3001 * Fixed the disconnection handling to Irssi SILC Client.
3002 The application must call silc_client_close_connection
3003 in ops->connect client operation in case of failure of
3004 the connection. Affected file is
3005 irssi/src/silc/core/client_ops.c.
3007 * Do not set sock->protocol to NULL in the function
3008 silc_client_close_connection after executing the protocol's
3009 final callback since the sock might not be valid anymore.
3010 Affected file lib/silcclient/client.c.
3012 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Do not enable SILC_THREADS if the linking with libpthread
3015 did not happen. Affected file configure.in.pre.
3017 * Added notion to protocol specification that server must
3018 verify the sent authentication payload with CMODE when
3019 setting the channel founder key. Implemented it to the
3020 server. Affected file silcd/command.c.
3022 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Added _EXTRA_DIST SILC distribution variable to the
3025 distributions file. It is used to conditionally add extra
3026 files or directories to the specific distribution. Affected
3027 files ./prepare, Makefile.am.pre and distributions.
3029 Removed the `_' from the start of the distribution names.
3032 * Added README.WIN32 for instructions to compile the Toolkit
3035 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Fixed a double free in disconnection in the server. Affected
3038 file is silcd/server.c.
3040 * Fixed the lib/silcske/groups.c to work now also with GMP
3041 MP library. The string conversion did not work when using
3042 specific base and the base is indicated in the string as well.
3044 * Created win32/ directory which now includes MSVC++ specific
3045 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3046 It will appear only in the toolkit distribution
3048 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3050 * Changed the key material distribution function in case when
3051 the hash output is too short. The data is now concatenated
3052 a bit differently than it used to. Made the change to the
3053 SKE protocol specification.
3055 * Added better GMP detection to configure.in.pre. A patch
3058 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Fixed a minor bug in SKE that might cause some problem on
3061 some platforms. Affected file lib/silcske/silcske.c.
3063 * Added the cookie checking for initiator in the SKE. It checks
3064 that the responder returns the sent cookie unmodified. The
3065 affected file is lib/silcske/silcske.c. Added new SKE
3066 error type INVALID_COOKIE that can be sent during the
3067 negotiation. Fixed some memory leaks as well.
3069 * Added the "invalid cookie" error message to Irssi SILC client's
3072 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Added `task_max' field to the SilcClientParams to indicate
3075 the maximum tasks the scheduler can handle. If set to zero,
3076 default values are used. Affected file lib/silcclient/silcapi.h.
3078 * Fixed memory leaks in silc_client_close_connection. Affected
3079 file lib/silcclient/client.c.
3081 * Added silc_client_del_client_entry to client library to free
3082 all memory of given client entry. Affected file is
3083 lib/silcclient/idlist.[ch].
3085 * Added new functions silc_client_del_channel and
3086 silc_client_del_server to delete channel and server entries.
3087 Affected file lib/silcclient/[silcapi.h/idlist.c].
3089 * Removed silc_client_del_client_by_id from silcapi.h.
3091 * Fixed the INFO command to return the server's own info
3092 correctly when querying by Server ID. Affected file is
3095 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Removed the non-blocking settings in WIN32 code in the
3098 silc_sock_[read/write] and added SleepEx instead. Affected
3099 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3100 of input data is now checked with FIONREAD and ioctlsocket.
3102 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Call silc_schedule_task_del_by_context in the
3105 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3106 Affected file lib/silccore/silcprotocol.c.
3108 * Call silc_protocol_cancel for active protocols in the
3109 silc_server_close_connection if the funtion
3110 silc_server_free_sock_user_data has not been called.
3111 Affected file silcd/server.c.
3113 * Generic tasks cannot be deleted using the del_by_fd
3114 task deleting function since generic tasks does not match
3115 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3117 * Added a notion to SILCOPER help file that the SILCOPER works
3118 only on router server, not on normal server.
3120 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Added for WIN32 support for the new scheduler as well.
3123 Affected file lib/silcutil/win32/silcwin32schedule.c.
3125 * Fixed the SHA1 implementation to work on various platforms.
3127 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3130 API. It is part of the scheduler now. Everything else is
3131 as previously but some functions has changed their names.
3132 Checkout the lib/silcutil/silcschedule.h for the interface.
3133 Updated all applications to use the new interface. Affected
3134 files are lib/silcutil/silcschedule.[ch].
3136 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3138 * Found a bug in the SKE implementation. The HASH value,
3139 specified by the protocol, was not computed correctly. The
3140 public key of the responder was not added to the computation
3141 even though it is mandatory. Affected file lib/silcske/silcske.c.
3142 This unfortunately causes incompatibilities with older
3143 clients and servers.
3145 * Added WIN32 specific network init and uninit functions:
3146 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3147 the Winsock2. Affected file lib/silcutil/silcnet.h and
3148 lib/silcutil/win32/silcwin32net.c.
3150 * Set the socket always to nonblocking mode on WIN32 after
3151 reading data or writing data. Affected file is
3152 lib/silcutil/win32/silcwin32sockconn.c.
3154 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Fixed various compilation problems under WIN32. Affected
3157 files lib/silcutil/win32/silcwin32thread.c and
3158 lib/silcutil/win32/silcwin32schedule.c.
3160 * Removed all _internal.h #includes from public header
3161 files. Internal headers must never be included from
3164 Removed also the lib/silcske/payload_internal.h file.
3166 * All include files that may be needed (public and some others
3167 included by the public headers) by application developers are
3168 now copied to the ./includes directory. It does not copy any
3169 internal headers. Affected file Makefile.defines.pre and all
3170 Makefile.am's under lib/ and subdirs.
3172 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Do not change the ~/.silc directory's permissions automatically.
3175 Affected file irssi/src/silc/core/clientutil.c.
3177 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Do not cancel the protocol in silc_server_close_connection
3180 it might cause recursion. Now cancelled in the function
3181 silc_server_free_sock_user_data. Affected file silcd/server.c.
3183 * Fixed the silc_server_remove_clients_by_server to regenerate
3184 the channel keys correctly finally. Added also new function
3185 silc_server_remove_clients_channels to actually do it.
3186 Affected file silcd/server.c.
3188 * Fixed the silc_server_new_channel to not crash by giving
3189 wrong router to the new channel. Affected file is
3190 silcd/packet_receive.c.
3192 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3195 which is given as argument to the silc_client_alloc now.
3196 It can be used to configure the client and set various parameters
3197 that affect the function of the client.
3199 * The USERS command in server did not check whether the channel
3200 is private or secret. Affected file silcd/command.c.
3202 * Added new argument to the USERS command in protocol specification.
3203 The USERS command now can take the channel name as argument
3204 as well. Added support for this in client and server and
3205 updated the protocol specs.
3207 * Completed the GETKEY command in client. It can be now used
3208 to fetch also servers public key not only some clients.
3209 Affected files lib/silcclient/command[_reply].c.
3211 * Added silc_client_get_server to return server entry by the
3212 server name. Affected files lib/silcclient/silcapi.h and
3215 * Redefined the IDENTIFY command in protocol specification to be
3216 more generic. It now can be used to query information about
3217 any entity in the SILC Network, including clients, servers and
3218 channels. The query may be based either the entity's name
3219 or the ID. Added support for this in both client and server.
3221 Affected files silcd/command.c and lib/silcclient/command.c
3222 and command_reply.c.
3224 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3225 the _from_client and _from_server functions. Affected file
3228 * Added silc_client_get_channel_by_id_resolve to the file
3229 lib/silcclient/silcapi.h to resolve channel information by
3230 its ID. Added also silc_client_get_channel_by_id that
3231 does not resolve it from the server.
3233 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Added SilcServerEntry context into the client library
3236 to represent one server. The INFO command now allocates
3237 these to save the resolved server info. For now on the
3238 client library will also keep information about servers,
3239 connected and resolved with INFO.
3241 The INFO command now allocates the SilcServerEntry context
3242 and saves the server info there. The COMMAND_REPLY in
3243 the INFO now returns the parameters to application in
3244 same order as defined in the protocol specification.
3246 The entries are cached in the client->server_cache.
3248 * The INFO command is now issued after received the Client ID
3249 from the server. Affected file lib/silcclient/client.c.
3251 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3252 to the application as the mode changer might be server.
3253 It is guaranteed that NULL is not returned anymore to the
3254 application. Affected file lib/silcclient/client_notify.c.
3256 The ID Type is now also passed to the application so that
3257 it can check whether the returned entry is SilcClientEntry
3260 Added new function silc_client_get_server_by_id to return
3261 the server entry by ID. Affected files are the
3262 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3264 * Do not create the channel in the Irssi SILC Client when issuing
3265 the JOIN command but when received the sucessful JOIN command
3266 reply. Otherwise the channel might get created even though we
3267 could not join it. The Affected file is
3268 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3270 * Fixed a channel joining bug in router. The router must also
3271 check the channel modes, invite and ban lists etc. when serving
3272 the JOIN command sent by normal server. Affected file is
3273 silcd/command.c. The router now resolves the client's
3274 information from the server who sent the JOIN command if it
3275 does not know it, and processes the JOIN command only after
3278 * Changed the SilcCommandCb to take new argument; void *context2.
3279 Affected file lib/silccore/silccommand.h
3281 The second argument in the command callbacks in the server now
3282 includes the SilcServerCommandReplyContext if the command was
3283 called as pending command callback from the command reply.
3284 Otherwise it is NULL. When called as pending the status of the
3285 command reply will be checked and if it was erronous the
3286 error will be sent to the original sender of the command.
3287 This way the client always receives the error messages even
3288 though the server was actually the one who received the error
3289 when it resent the command to router, for example. Affected
3290 files silcd/command[_reply].[ch].
3292 * Fixed sending WHOWAS command's error message to client if
3293 the requested client could not be found. It was missing.
3296 * Changed the CMODE and CUMODE commands reply arguments in the
3297 protocol specification. The Channel ID is now sent in both
3298 of the commands to identify the channel. Implemented this
3299 new feature to the client and server. Affected files
3300 lib/silcclient/command_reply.c and silcd/command.c.
3302 * Made better checks for invite and ban lists in the JOIN
3303 command in server. Affected file silcd/command.c.
3305 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * The server now performs the incoming host IP/DNS lookup
3308 using the silc_socket_host_lookup and thus does not block
3309 the server anymore. Affected file silcd/server.c.
3311 * Completed the multi-thread support for SILC Scheduler in
3312 the lib/silcutil/silcschedule.c.
3314 * Fixed the configure.in.pre to detect the pthread correctly
3317 * Fixed a deadlock in silc_task_queue_wakeup in the file
3318 lib/silcutil/silctask.c.
3320 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Added new function silc_schedule_wakeup that is used in
3323 multi-threaded environment to wakeup the main thread's
3324 schduler. It needs to be used when a thread adds a new task
3325 or removes a task from task queues. After waking up, the
3326 scheduler will detect the task queue changes. If threads
3327 support is not compiled in this function has no effect.
3328 Implemented the wakeup mechanism to both Unix and WIN32
3329 systems. Affected files are lib/silcutil/silcschedule.[ch],
3330 lib/silcutil/unix/silcunixschedule.c and the
3331 lib/silcutil/win32/silcwin32schedule.c.
3333 * Added new function silc_task_queue_wakeup to wakeup the
3334 scheduler by the specified task queue. Affected file
3335 lib/silcutil/silctask.[ch].
3337 * The silc_socket_host_lookup_start now wakes up the scheduler
3338 after adding the timeout task. Affected file is
3339 lib/silcutil/silcsockconn.c.
3341 * The silc_socket_host_lookup is synchronous now if the threads
3342 support is not compiled in. However, the callback is still
3343 called asyncronously through the scheduler, anyway. Affected
3344 file lib/silcutil/silcsockconn.c.
3346 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3348 * Added new function silc_socket_host_lookup to perform
3349 asynchronous IP and FQDN lookups for the socket connection.
3350 Affected files lib/silcutil/silcsockconn.[ch].
3352 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3355 that may or may not compile the mutex support in.
3357 Changed the silc_mutex_alloc interface. It allocates the
3358 mutex now to the sent pointer and returns TRUE or FALSE.
3360 Affected file lib/silcutil/silcmutex.h.
3362 * Wrote the SILC Task Queue interface to support multi-threads.
3363 Affected file lib/silcutil/silctask.[ch].
3365 * Wrote the SILC Scheduler to support multi-threads. Affected
3366 file lib/silcutil/silcschedule.c.
3368 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3371 in lib/silcutil/win32/.
3373 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Defined SILC Mutex API and SILC Thread API and implemented
3376 them for Unix. Affected files are
3377 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3378 lib/silcutil/unix/silcunixmutex.c and
3379 lib/silcutil/unix/silcunixthread.c.
3381 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Fixed the silc_server_remove_clients_by_server's channel
3384 key re-generation. The hash table handling was incorrect
3385 and would not work with many channels. Affected file is
3388 * Fixed some memory leaks around the server code.
3390 * Rewrote the silc_server_get_users_on_channel to support IPv6
3391 based Client ID's. Affected file silcd/server.c.
3393 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3394 specification. However, a separate document must be written
3395 to define the detailed signing procedure and the payload
3396 associated with the flag. Defined the flag to the
3397 lib/silccore/silcchannel.h as well.
3399 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Changed the dynamic tables to static size tables in the
3402 lib/silccrypt/silchmac.c.
3404 * Removed GCC dependencies from the code. A patch by cras.
3406 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Do not show the error "Error receiving packet bla bla"
3409 in server if it really was not an error (-2 means that reading
3410 is pending). Affected file silcd/server.c.
3412 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Fixed a possible crash in silc_server_remove_clients_by_server
3415 in silcd/server.c. Fixed there also some memory leaks.
3417 * Fixed the silc_idlist_replace_client_id. It could replace
3418 wrong key in the hash table. Affected file silcd/idlist.c.
3420 * Do not check whether there are global users on the channel
3421 if the channel->global_users is FALSE. Affected functions
3422 silc_server_remove_from_one_channel and
3423 silc_server_remove_from_channels in silcd/server.c. Also,
3424 do not check if the removed client is local as we can be
3425 sure that global client was not removed from the channel
3426 and checking for global users is not needed.
3428 * The silc_server_remove_clients_by_server now re-generates
3429 the channel keys correctly for those channels that had
3430 clients removed from them. Affected file silcd/server.c.
3432 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Found the reason of random crashes in the server. We weren't
3435 ignoring the SIGPIPE signal (which can be sent in write())
3436 and it crashed the server. Affected file silcd/silcd.c.
3438 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3440 * Assure that sock->user_data is not NULL in the function
3441 silc_server_packet_send in silcd/packet_send.c.
3443 * Disconnect the remote connection if it could not be added
3444 to any ID lists in the server. The affected file is
3447 * Check in silc_server_packet_send[_real/dest] that the
3448 socket is not disconnecting and ignore the data if it is.
3449 Affected file silcd/packet_send.c.
3451 * Define inline to __inline on native WIN32 compilation.
3452 Affected file includes/silcwin32.h.
3454 * Added some explicit type casts for inline code since MSVC
3455 require them. Affected files lib/silcutil/silcbuffer.h,
3456 lib/trq/silcdlist.h and lib/trq/silclist.h.
3458 * Print warning in log files from now on if the packet
3459 decryption fails. Affected file silcd/server.c.
3461 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Changed the `say' client operation's interface to accept
3464 new `type' argument to indicate the type of the message sent
3465 by the library. The application may filter the library's
3466 messages according the type. The affected file is the
3467 lib/silcclient/silcapi.h.
3469 * Added two new functions to lib/silcclient/silcapi.h:
3470 silc_client_del_client and silc_client_del_client_by_id.
3471 Affected file lib/silcclient/idlist.c.
3473 * Moved the clientincludes.h from includes/ to silc/ and
3474 serverincludes.h from includes/ to silcd/.
3476 * The modes for the CMODE and CUMODE are now passed as
3477 uint32 for application with COMMAND_REPLY. The affected
3478 file is lib/silcclient/command_reply.c.
3480 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3482 * /WHOIS without arguments shows client's own information.
3483 Affected file lib/silcclient/command.c.
3485 * Changed PING to not accept any arguments. The specs
3486 says that client can ping only the connected server so
3487 requiring an argument is not needed. Affected file is
3488 lib/silcclient/command.c.
3490 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Fixed a fatal bug in private message sending and reception
3493 encryption and decryption when using private message keys.
3494 The implementation was incorrect and did not follow the
3495 specification. It causd that some of the message were
3496 lost since it did not use the sending and receiving keys
3497 as the protocol suggests. This has been fixed and will cause
3498 incompatibilities with older clients when sending private
3499 message encrypted with private message keys. Affected files
3500 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3501 and various other in Irssi SILC Client.
3503 Added `responder' boolean argument to the functions
3504 silc_client_add_private_message_key[_ske] to indicate when
3505 the key is added as responder or initiator of the key
3508 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Removed the silc_ske_check_version function and created
3511 a SilcSKECheckVersion callback. Added also a function
3512 silc_ske_set_callbacks that is now used to set all SKE
3513 callbacks. The callback functions are not given to
3514 the SKE functions anymore, but this function is used to
3517 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3519 * Added `silc_version' argument to the silc_client_alloc
3520 to define the version of the application for the library.
3521 The library will use the version string to compare it
3522 against the remote host's (usually a server) version
3523 string. Affected file lib/silcclient/silcapi.h
3525 * Added the KE protocol context to Key Agreement context
3526 in client library so that we can abort the SKE if it
3527 is in process when we get timeout. Affected file is
3528 lib/silcclient/client_keyagr.c.
3530 * Do not resolve the client ID forever if it returns in the
3531 first time that such client does not exist. This was done
3532 for example with private message. Affected file is
3533 lib/silcclient/client_prvmsg.c.
3535 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Do not add regex.h for WIN32. The affected file
3538 includes/silcincludes.h.
3540 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3541 not work yet 100%. It generates the DLL's automatically
3542 when compiling with --with-win32 under cygwin.
3544 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * lib/contrib/regex.c is not compiled on WIN32.
3548 * Added silc_net_get_socket_opt function to the
3549 lib/silcutil/silcnet.h.
3551 * Added includes/silcwin32.h for WIN32 specific includes
3554 * Do not use ptime structure or any of the posix process
3555 functions on WIN32 in lib/silccrypt/silrng.c.
3557 * Added silc_gettimeofday to provide generic function
3558 for struct timeval on all platforms. Added the function
3559 to lib/silcutil/silcutil.h.
3561 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3563 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3564 library as they clearly belong there. As a plus side we
3565 can make the actual socket connection routines platform
3568 Added also new generic function silc_socket_read and
3569 silc_socket_write (that used to be silc_packet_[read/write].
3570 The implementation of these are platform specific.
3572 * Added WIN32 specific routines of silc_socket_[read/write]
3573 to lib/silcutil/win32/silcwin32sockconn.c.
3575 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3577 * Added preliminary support for native WIN32 compilation under
3578 cygwin (using the -mno-cygwin option for GCC) to the
3579 ./configure.in.pre. The --with-win32 now prepares the
3580 compilation for native WIN32.
3582 * Rewrote the SILC Scheduler interface in the file
3583 lib/silcutil/silcschedule.h. The scheduler is now context
3584 based and does not have anymore any global static scheduler.
3585 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3586 and created lib/silcutil/win32 directory for WIN32 based
3589 * Added Unix specific network routines to the
3590 lib/silcutil/unix/silcunixnet.c and the old
3591 lib/silcutil/silcnet.c includes now only generic routines.
3593 Added WIN32 specific network routines to the
3594 lib/silcutil/win32/silcwin32net.c.
3596 * Added Unix specific utility functions from the
3597 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3599 * Added WIN32 SILC Scheduler to the file
3600 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3603 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Do not handle JOIN notify in the server if the target client
3606 is not registered (idata->registered == FALSE). The affected
3607 file is silcd/packet_receive.c.
3609 * Update the nickrec->founder in event_cumode in the Irssi SILC
3610 client. Affected file irssi/src/silc/core/silc-channels.c.
3612 * Fixed the CUMODE_CHANGE notify handling in the server when
3613 server and router are announcing their clients on channels.
3614 Now the mode changes are saved and notified correctly. The
3615 affected file is /silcd/packet_receive.c.
3617 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3618 They really did not replace the cache entry in the ID Cache.
3619 Now they do that. Affected file silcd/idlist.c.
3621 * Fixed the KICK notify handling in the Irssi SILC client to
3622 update the channel records so that the kicked client does not
3623 appear to be on the channel. The affected file is
3624 irssi/src/silc/core/silc-channels.c.
3626 * Always update the conn->current_channel when executing command
3627 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3629 * Fixed the KILL notify handling in Irssi SILC client to remove
3630 the killed client on all channels.
3632 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Fixed the silc_parse_command_line to remove extra spaces
3635 from the start and end of the arguments. Affected file is
3636 lib/silcutil/silcutil.c.
3638 * Cancel and free any active protocol in the function
3639 silc_server_close_connection. Affected file silcd/server.c.
3641 * Cancel and free any active protocol in the function
3642 silc_client_close_connction. Affected file is
3643 lib/silcclient/client.c.
3645 * Do not execute the KILL command for clients that are in
3646 history (ie. they are not in the network). Affected file is
3649 * Fixed KILL notify handling, client does not crash anymore.
3650 Affected file irssi/src/silc/core/silc-channels.c.
3652 * Reduced the default packet buffer size from 2048 to 1024 in
3653 lib/silccore/silcpacket.c.
3655 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3656 counter to the SKE context that is incresed when the SKE library
3657 performs async operation outside the library. If the outside
3658 process frees the SKE context and FREED status will be set
3659 and the library will detect after the sync operation that the
3660 libary is freed. The affected files are
3661 lib/silcske/silcske[_status].[ch].
3663 * Resolve the client entry information in the function
3664 silc_client_channel_message to assure that NULL pointer is not
3665 passed as client entry to the application. */
3667 * Fixed the task timeout calculation to assure that there is
3668 never negative timeouts. The affected file is
3669 lib/silcutil/silcschedule.c.
3671 * Fixed the channel user mode notification sending in server.
3672 It was sent point-to-point to the router (or to server by router)
3673 but it needs to be destined to a channel. The routines now
3674 supports sending the channel user mode notifys to the channels
3675 when announcing clients and channels. Affected files are
3676 silcd/server.c and silcd/packet_receive.c.
3678 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3679 It did not actually replace the old channel entry in the cache.
3680 Affected file lib/silcclient/client_notify.c.
3682 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Fixed a possible crash in silc_packet_send_prepare. It now
3685 assures always that there is enough space in the buffer and
3686 at the tail area of the buffer (for MAC).
3688 Fixed the inbound buffer reallocation in silc_packet_read.
3689 It was old code and did not handle the reallocation correctly.
3692 The affected file is lib/silccore/silcpacket.c.
3694 * Fixed buffer overflow in silc_parse_nickname in the file
3695 lib/silcutil/silcutil.c.
3697 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * make install generates new server keys only if there is not
3702 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3705 Added check that if the NOREPLY is set then we will not send
3706 the away message. This avoids infinite loop of away messages
3707 if both clients are away. The affected file is
3708 lib/silcclient/client_prvmsg.c.
3710 * Fixed client crash if /NICK was given without arguments.
3711 Affected file lib/silcclient/command.c.
3713 * Server does not send the invite list in INVITE command back
3714 to the client if the list was not altered. Added this notion
3715 to the protocol spec as well. Affected file silcd/command.c.
3717 Fixed possible crash in INVITE command by checking the
3718 value of silc_server_get_client_route command.
3720 * Fixed the INVITE notify type handling. The arguments are now
3721 taken in correct order and client does not crash. The affected
3722 file is irssi/src/silc/core/silc-channels.c.
3724 Removed the "Inviting xxx to channel" message from the
3725 client library away and let the application handle it.
3726 Affected file lib/silcclient/command.c. Added that message
3727 to Irssi SILC client's message formats.
3729 * Fixed CMODE command crash in client. It now checks the
3730 amount of arguments correctly and does not crash. The affected
3731 file is lib/silcclient/command.c.
3733 * Do not create new channel automatically in silc_channels_join
3734 but check whether the channel by that name already exists.
3735 Affected file irssi/silc/core/silc-channels.c.
3737 * Do not send the SERVER_SIGNOFF to router if the disconnected
3738 entity was the router. Affected file silcd/server.c.
3740 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3741 SILC client as it was missing from there.
3743 Added the handling of the KICK notify to the Irssi SILC client
3744 as it was missing. Added "you have been kicked" message to
3745 Irssi SILC client's message modules formats.
3747 Added the handing of the KILL notify to the Irssi SILC client
3748 as it was missing. Added the kill message module formats
3751 The affected file is irssi/src/silc/core/silc-channels.c.
3753 * The router did not save the channel mode the server announced.
3754 Affected file silcd/packet_receive.c.
3756 * Fixed a possible crash in INFO command in server. If the
3757 server did not provide the server info it crashed. Affected
3758 file silcd/command.c.
3760 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Fixed the GETKEY command in the server to check also the
3763 global list. Otherwise the GETKEY would not work correctly
3764 in normal SILC server. Affected file silcd/command.c.
3766 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Fixed GETKEY crash, it crashed if the command did not succseed.
3770 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3773 is now real and not just an macro interface to GMP.
3775 Removed the entire GMP from the source tree and imported new
3776 NSS MPI library instead. Reason for removing GMP is that it is
3777 extremely large and compiles extremely slow. The NSS MPI
3778 is only a few files and compiles in less than 10 seconds.
3779 The speed is also about the same as GMP. The MPI is imported
3780 to lib/silcmath/mpi.
3782 If the system has GMP installed we will still use the GMP.
3783 If it is not then the NSS MPI will be compiled.
3785 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Merged a long nickname (127 characters long) crash bugfix from
3788 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3790 * Merged a freed memory reference bugfix from Irssi CVS tree.
3791 Affected file irssi/src/core/commands.c.
3793 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Added the server's public key sving and verification to the
3796 server when performing the SKE. This was missing and the
3797 remote server's (or router's) public key was accepted without
3798 checking whether we have it previously or trust it at all.
3799 Affected file silcd/protocol.c.
3801 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Check in the silc_server_timeout_remote if protocol is active
3804 and make sure that the protocol's final callback is called so
3805 that all memory if freed. Affected file silcd/server.c.
3807 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * silc_server_whois_send_reply crashed the server if the nickname
3810 was 127 characters long. Affected file silcd/command.c.
3812 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Added sanity check to the silc_server_new_client. If the hostname
3815 is provided inside username then check that the provided hostname
3816 really is the same as the resolved one. If the hostname was not
3817 resolved then check it from the public key. Affected file is
3818 silcd/packet_receive.c.
3820 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3821 if the server disconnected us and the connection is not valid
3822 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3824 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3825 the library to the lib/silcutil/silcutil.[ch].
3827 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3829 * Close log file after open. Affected file
3830 lib/silcutil/silclog.c.
3832 * Check whether sock == NULL in silc_client_send_packet and return
3833 if it is. Affected file lib/silcclient/silcclient.c.
3835 * Check rec->entry == NULL in the Irssi SILC Client before
3836 sending the channel message. Affecte file is
3837 irssi/src/silc/core/silc-servers.c.
3839 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Merged a splitted window bugfix from Irssi CVS tree. The
3842 affected file is irssi/src/fe-text/textbuffer-view.c.
3844 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3845 It did not print nickname.
3847 * Improved the distributions system a bit.
3849 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3852 irssi/src/fe-text/gui-window.c.
3854 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3855 to in-active server. The affected file is
3856 irssi/src/silc/core/client_ops.c.
3858 * Resolve the client in USERS command reply if the entry does
3859 not have username resolved. The affected file is
3860 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3861 command to WHOIS command to really resolve stuff. The USERS
3862 is not used any more in any critical section so WHOIS can
3863 be used even though it might be slower than IDENTIFY.
3865 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3868 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Changed the protocol API a bit more consistent in the
3871 lib/silccore/silcprotocol.[ch].
3873 * Changed the following headers to ROBODoc format:
3875 lib/silccore/silcpayload.h
3876 lib/silccore/silcprotocol.h
3877 lib/silccore/silcsockconn.h
3879 All core library headers are now formatted.
3881 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Fixed a bug in Irssi SILC client; do not show that you are
3884 server/router operator if you really are not. Affected file is
3885 irssi/src/silc/core/client_ops.c.
3887 * Renamed silc_command_free_payload to silc_command_payload_free.
3888 Affected file lib/silccore/silccommand.h
3890 * Added silcmath.h to include the prototoypes of various routines
3891 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3894 * Changed the following headers to ROBODoc format:
3896 lib/silccore/silcchannel.h
3897 lib/silccore/silccommand.h
3898 lib/silccore/silcid.h
3899 lib/silccore/silcidcache.h
3900 lib/silccore/silcmode.h
3901 lib/silccore/silcnotify.h
3902 lib/silccore/silcpacket.h
3903 lib/silcmath/silcmath.h
3905 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Added checking to the server code not to start the server if
3908 ciphers and stuff are not configured properly. Affected files
3909 silcd/serverconfig.[h] and silcd/server.c.
3911 * Changed the layout of the header files of the public interfaces
3912 in the SILC libraries. The new layout supports ROBODoc
3913 documentation tool (and some others) so that it is easy to create
3914 a library reference manual. All the other headers and source
3915 code must still follow the CodingStyle document. Also source
3916 code must not include these ROBODoc stuffs, only the headers.
3917 Furthermore, all public interface headers must now be named
3918 by using `silc' prefix, example: silcapi.h, silccipher.h.
3919 Some files were renamed due to this. All the other headers
3920 must not be used as public interfaces. I will update the
3921 CodingStyle document later. Changed following headers, so far:
3923 lib/silcclient/silcapi.h
3924 lib/silccore/silcauth.h
3925 lib/silccore/silcprivate.h
3926 lib/silccrypt/silcdh.h
3928 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Removed silc_client_packet_send_flush from the client library
3933 as it is not needed. Affected file lib/silcclient/client.[ch].
3935 * Added printing of message of unresolved authentication method
3936 to the Irssi SILC client. Added it to the module formats.
3937 Removed the same message from the client library.
3939 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Added new distribution feature, DISTLABEL. Every distribution
3942 can define own preprocessor label that can be used in the
3943 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3944 file distributions, acconfig.h.pre and prepare.
3946 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added Makefile.defines_int to include the actual definitions
3949 for Makefile.defines.in. Tested the new distribution system,
3950 created distributions and tested installation.
3952 * Added AWAY message printing to the Irssi SILC client. Added
3953 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3955 * Added SCONNECT command to call the SILC's CONNECT command.
3956 Cannot use CONNECT directly since Irssi uses that internally.
3957 Affected file irssi/src/silc/core/silc-servers.c.
3959 Added ACTION local command. It is same as ME command but takes
3960 the channel as mandatory argument.
3962 Rewrote some of the Irssi's help files to suite for SILC
3965 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3967 * Added Makefile.defines[.in] that should for now on be included
3968 in all Makefile.am file in the source tree. That file includes
3969 all common compilation definitions for SILC source tree.
3971 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Minor changes to the ./prepare script to change the package
3974 name according the distribution name to the configure.in.
3976 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Created new distribution system. Added file `distributions'
3979 that defines all the distributions that can be created out of
3980 the SILC source tree. The ./prepare script now reads that
3981 file to determine how to prepare the distributions. The
3982 first argument to the ./prepare is the name of the distribution
3983 and second is the version of the distribution. If given
3984 without arguments it creates the default (toolkit) distribution
3985 with the default version (defined in ./prepare).
3987 All Makefile.am files that are subject to the distributions
3988 are now named as Makefile.am.pre. These are ./Makefile.am
3989 and lib/Makefile.am. Others may be changed later.
3991 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Added invite list, ban list, some key management and connection
3994 error message printing to module formats in the Irssi SILC client.
3996 * Added new silc_client_set_away_message to set the away message
3997 that is back to the person who sent private message. The
3998 affected file lib/silcclient/silcapi.h and the
3999 lib/silcclient/client_prvmsg.c.
4001 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Fixed the private message sending in the Irssi SILC client,
4004 added local command KEY to the Irssi SILC client.
4006 Added key management and key agreement message formats to the
4007 irssi/src/fe-common/silc/module-formats.[ch].
4009 Added USERS (alias WHO) printing, server/router operator
4010 indication and LIST command printing to the module formats.
4012 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Fixed channel joining notify handling, cumode notify handling
4015 from Irssi SILC client.
4017 * Added SILC specific module-formats to the Irssi SILC client so
4018 that SILC specific message hilighting, colors etc is possible.
4019 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4021 Added channel mode, channel user mode, actions, notices,
4022 whois and whowas printing to the the module-formats.c.
4024 * Fixed a bug in channel deletion in the server. The channel
4025 is not left to the cache even if the channel founder auth mode
4026 is set when there are no users anymore on the channel. Affected
4027 file silcd/server.c.
4029 * The silc_net_localhost now resolves the entire hostname including
4030 the domain name. Affected file lib/silcutil/silcnet.c.
4032 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Changed the ask_passphrase client operation to be ascynchronous.
4035 It has now a completion callback and a context that the
4036 application must call after it has got the passphrase from
4037 the user. Affected files lib/silcclient/silcapi.h,
4038 lib/silcclient/protocol.c, lib/silcclient/command.c and
4041 Added SilcAskPassphrase callback that the application calls
4042 to deliver the passphrase to the library.
4044 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4045 The public key verification and especially a certificate
4046 verification is asynchronous procedure.
4048 Added new SILC_SKE_STATUS_PENDING status to indicate the
4049 request is pending and a callback will be called to finalize
4052 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4053 indicate that remote end did not send its public key (or
4054 certificate), even though we require it. Added check for this
4055 condition in the SKE. This was a security bug, now fixed.
4057 Defined new SilcSKEVerifyCbCompletion callback that is called
4058 when the verification process is completed.
4060 The affected files lib/silcske/silcske_status.h and
4061 lib/silcske/silcske.[ch].
4063 * Changed the verify_public_key client operation to be async
4064 as well. Defined SilcVerifyPublicKey callback that is used to
4065 indicate the success of the public key verification process.
4067 Changed the server and client to use the new async client
4070 * Changed the Irssi SILC client's internal scheduler to be called
4071 twice as many times as it used to be. As a result the client
4072 should be a bit faster now. Affected file is
4073 irssi/src/silc/core/silc-core.c.
4075 * Added support to Irssi SILC client of asynchronous public key
4076 verification and passphrase inquiry. Affected file is
4077 irssi/src/silc/core/silc-core.c.
4079 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Do not say "You have left channel %s" in client library.
4082 Moved it to the application. Affected files are
4083 lib/silcclient/command.c and silc/client_ops.c.
4085 * Fixed silc_client_get_clients. Command context was not
4086 duplicated and was freed memory in the callback. Affected
4087 file lib/silcclient/idlist.c.
4089 * Do not say "you are now talking..." on JOIN command in the
4090 client library. The appliation must handle it.
4092 * Do not say ".. changed topic to" in command reply in the
4093 client libary. The application must handle it.
4095 * Fixed TOPIC command sending in the client library.
4097 * Fixed a memory leak in silc_client_command_free in the file
4098 lib/silcclient/command.c.
4100 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Imported a modified version of Irssi client to the source tree.
4103 The Irssi will be used to create a new client called
4104 Irssi SILC. Imported to irssi/.
4106 Added silc_core_init_finish function to the Irssi. Affected
4107 file irssi/configure.in.
4109 A lot changes in the Makefile.ams around the irssi tree.
4111 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Do not rehash if the new size is same as the old size of the
4114 hash table, in the silc_hash_table_rehash*. The affected file
4115 lib/silcutil/silchashtable.c.
4117 * Replaced hash_table_del_by_context calls from the server
4118 (when channel->user_list and client->channels) to the
4119 hash_table_del as it is sufficient and faster.
4121 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Added silc_hash_table_list, silc_hash_table_get and the
4124 SilcHashTableList structure to provide an alternative way to
4125 traverse the hash table. The affected files are
4126 lib/silcutil/silchashtable.[ch].
4128 * Changed the server's idlist routines to use the hash table
4129 routines to optimize the code.
4131 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Replaced the client entry's `channel' list and channel entry's
4134 `user_list' list to hash tables for optimized lookup. Changed
4135 the code to use the hash table interface around the code.
4136 Affected file lib/silcd/idlist.[ch].
4138 * Added `auto_rehash' boolean argument to the function
4139 silc_hash_table_alloc to indicate whether the hash table should
4140 auto-rehash when it thinks is appropriate time. It will
4141 increase the hash table size if the there is twice as much
4142 entries in the table than the size of the table, and will
4143 decrease the size if there are twice as less entries than
4144 the size of the table.
4146 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4150 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * silc_idcache_purge_by_context deletes the entry now by context
4153 as it is supposed to do. Affected file lib/silccore/idcache.c.
4155 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4156 client is not anymore valid (WHOWAS givens the info) and not
4157 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4159 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Removed the `data' and `data_len' arguments from the ID Cache
4162 interfaces and added `name' argument. ID Cache does not handle
4163 anymore the binary data only a names associated with given ID.
4165 * When hashing a Client ID with silc_hash_id the entire ID is
4166 not hashed anymore, instead only the hash of the Client ID is
4167 hashed. This way we can access the Client ID from the cache
4168 with Client ID but with the hash of the ID (which is a hash of
4169 the nickname) as well without any difference in performance.
4171 Added also silc_idcache_find_by_id_one_ext to do one on one
4172 searching when we have the actual ID. Added also function
4173 silc_hash_client_id_compare. The affected files are
4174 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4176 * When hashing the name associated with a ID it is always done
4177 in lowercase. This way we can access the cache without worrying
4178 about case-sensitivity, even though, for example nicknames are
4181 * Fixed a bug in server with channel message sending. It put
4182 wrong ID type as destination ID. The affected file
4183 silcd/packet_send.c.
4185 * silc_idcache_del_by_context now deletes from all hash tables
4186 by context. Affected file lib/silccore/idcache.c.
4188 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Changed the client library to use the new ID Cache interface.
4191 Changes around the source tree.
4193 * Added silc_hash_table_rehash_ext to rehash with specific
4194 hash function. Affected file lib/silcutil/silchashtable.[ch].
4196 * Added silc_hash_string_compare to compare two strings in the
4197 hash table. Affected file lib/silcutil/silcutil.[ch].
4199 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Added new function silc_idcache_del_by_context into the
4202 lib/silccore/idcache.[ch].
4204 * Changed the server's ID list routines to use the new ID Cache
4205 interface. Changes around the source tree.
4207 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Added silc_hash_table_del[_by_context]_ext functions in to the
4210 lib/silcutil/silchashtable.[ch].
4212 Removed silc_hash_table_find_all* routines and added new
4213 silc_hash_table_find_foreach to replace them.
4215 Added silc_hash_table_replace_ext function as extended
4216 replacing function. Separated the simple hash table interface
4217 from the extended hash table interface in the file
4218 lib/silcutil/silchashtable.h.
4220 * Fixed minor bugs and changed it to use some of the new
4221 hash table functions in lib/silccore/idcache.c
4223 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Added new function silc_hash_table_find_all to return all keys
4226 in the hash table by the specified key. As the hash table is
4227 collision resistant it also makes it possible to have several
4228 duplicate keys in the hash table. This function may be used to
4229 find all of the keys from the hash.
4231 Added user_context arguments to the SilcHashFunction,
4232 SilcHashCompare and SilcHashDestructor to deliver user specified
4235 Added new fuctions silc_hash_table_find[_all]_ext to do
4236 extended lookup with specified hash and compare functions and
4237 specified user contexts.
4239 Added new function silc_hash_table_add_ext to add the key
4240 with specified hash function and user context.
4242 Added new function silc_hash_table_foreach to traverse all
4243 entrys in the hash table. Added SilcHashForeach callback
4246 Added new function silc_hash_table_del_by_context to delete
4247 the entry only if the context associated with the key matches.
4249 Affected files are lib/silcutil/silchashtable.[ch].
4251 * Removed silc_hash_[server/client/channel]_id and added just
4252 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4253 silc_hash_id_compare to compare two ID's using as the hash table
4254 comparison function. Added also silc_hash_data to hash
4255 binary data and silc_hash_data_compare to compare it.
4257 * Removed silc_idlist_find_client_by_hash as it is not needed
4258 anymore. Affected file silcd/idlist.[ch].
4260 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4261 to use internally the SilcHashTable. The new ID Cache is a lot
4262 faster than the old one. Some of the ID Cache interface was also
4263 rewritten and obsolete and stupid functions were removed.
4265 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Added entry_count field to the SilcHashTable to keep the number
4268 of the entries in the table. Implemented the function
4269 silc_hash_table_rehash. Added new function
4270 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4272 Fixed a minor bug in silc_hash_table_free.
4274 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4275 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4276 into the lib/silcutil/silcutil.[ch].
4278 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Implemented a collision resistant hash table into the
4281 lib/silcutil/silchashtable[ch]. See the header and the source
4282 for the SilcHashTable API.
4284 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Merged dotconf version 1.0.2 into lib/dotconf.
4288 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Do not compile anything in lib/silcsim/* if the SIM support
4291 is not enabled. The tree should now compile without problems
4294 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Compiled the SILC under cygwin. Compiled and tested briefly
4297 without problems. More tests needed. The SIMs didn't compile
4300 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4302 * Fixed possible crash in silc_get_username in the
4303 lib/silcutil/silcutil.c.
4305 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Fixed a va_arg in silc/client_ops.c.
4309 * Oops, RC5 routines were named AES and caused some problems
4310 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4312 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Added new SilcIDIP structure into the lib/silccore/id.h and
4315 replaced the old `ip' fields from all SILC ID's to that type.
4316 This is a step towards IPv6 support.
4318 The silc_id_get_len takes now the ID as an extra argument.
4319 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4320 both IPv4 and IPv6 based ID's.
4322 The affected files are lib/silccore/id.[ch] and other files
4323 around the tree using these routines.
4325 * Removed the ID length arguments in server from various
4326 silc_server_send_notify_* routines -> they are not needed
4329 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Fixed memory leak in silc_encode_pem_file in the file
4332 lib/silcutil/silcutil.c.
4334 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Check minor version as well in the SKE. Affected files are
4337 silcd/protocol.c and lib/silcclient/protocol.c.
4339 * Added --identifier option to the server so that an identifier
4340 can be when creating the public key for the server. Affected
4341 file is silcd/silcd.c.
4343 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4344 lib/silccrypt/silcpkcs.c.
4346 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Register default ciphers and stuff when using -C option with
4349 the server. Affected file sildc/silcd.c.
4351 * Put back the servers public key filename format, it is better
4352 than the new one. For now, the client keys are saved with the
4353 new filename format. The affected file silc/client_ops.c.
4355 * Implemented the Cipher API for the rest of the ciphers that
4356 did not implement it or implemented it the wrong way.
4358 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Register default ciphers and stuff when using the -S option
4361 in the client. Affected file silc/silc.c. Same also when
4362 creating new key pair with -C option.
4364 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Fixed the silc_verify_public_key client operation function to
4367 save the public keys differently. The fingerprint is now
4368 used as filename and not the hostname. This way also the
4369 client keys are saved uniquely and not with hostnames. The
4370 affected file is silc/client_ops.c.
4372 * Trimmed the silc_hash_fingerprint function to remove extra
4373 whitespaces from the end of the fingerprint. The affected
4374 file is lib/silccrypt/silchash.c.
4378 * Added silc_cipher_register_default function to register all
4379 default ciphers. It can be used when configuration files
4380 does not exist and the application does not want any specific
4381 ciphers in any specific order.
4383 The SilcDList is now used as silc_cipher_list dynamically
4384 allocated cipher list. Removed the static list all together
4385 and now all ciphers must be allocated to the dynamic list.
4386 The silc_cipher_alloc routine was changed to check only the
4389 All silc_cipher_* routines that used to return int returns
4392 The affected files lib/silccrypt/silccrypt.[ch].
4394 * The same thing was done to silc_hash_* as for silc_cipher_*
4395 routines. Affected files lib/silccrypt/silchash.[ch].
4397 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4398 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4399 Added also silc_pkcs_[un]register[_default] functions.
4400 Removed the data_context from the PKCS API.
4402 * Added silc_hmac_register_default function to register default
4403 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4404 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4405 to unregister all hmacs at once.
4407 * Register the default ciphers, hash functions, PKCSs and HMACs
4408 if client's configuration file does not exist. The affected
4411 * The client did not load the hash functions from the SIM
4412 modules at all. Added support for this. Affected file is
4413 silc/clientconfig.c.
4415 * When decoding public key with silc_pkcs_public_key_decode, check
4416 the supported algorithm only if PKCS are registered. Affected
4417 file lib/silccrypt/silcpkcs.c. The same was done with the
4418 silc_pkcs_private_key_decode.
4420 * Fixed the SILC List routines to keep the list always in order.
4421 It used to change the list's order when traversing the list but
4422 not it preserves the order. Affected file lib/trq/silclist.h.
4424 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Added the client library to use the SilcSocketConnection's
4427 reference counter (by silc_socket_dup) to prevent the bug that
4428 the socket object may be freed underneath async operation.
4430 * The name resolv library checking fixes in the configure.in.pre.
4433 * Created new version of the protocol drafts for future
4434 development. The -03 drafts are the ones that will be changed
4435 in the trunk now and the -02 will remain as they are.
4437 * Send list of CUMODE notifys to the router when announcing
4438 the channel users to the router. Affected file silcd/server.c.
4439 If the router receiving channel founder CUMODE for a channel
4440 that already has channel founder it will send CUMODE notify
4441 to the sender to remove the channel founder rights from the
4442 announced client. Affected file silcd/packet_receive.c.
4444 * The CUMODE notify may now use Server ID as well as the entity
4445 who changes the mode. Updated protocool specs.
4447 * Updated INSTALL and README files.
4449 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * New web pages in the http://silc.pspt.fi. The pages was
4456 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Implemented the [DenyConnectin] config section in the server.
4459 Added silc_server_config_denied_conn to check whether incoming
4460 connection is denied. Affected file silcd/serverconfig.[ch].
4462 * Do not check the ports when checking the incoming configuration
4463 data if the port is 0, meaning any. Affected file is
4464 silcd/serverconfig.c.
4466 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Fixed buffer overflow in silc_string_compare in the file
4469 lib/silcutil/silcutil.c.
4471 * Fixed double free in silc_server_command_leave in the file
4474 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Fixed the version checking in the server. Affected file is
4479 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Fixed the configuration data fetching when accepting new
4482 connections in the server. Affected file silcd/server.c.
4484 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Added `sender_entry' argument to the function
4487 silc_server_packet_relay_to_channel so that we can check
4488 whether some destination actually belongs to the same route
4489 the sender belongs (ie, we must not resend the packet to the
4490 sender). Affected file silcd/packet_send.[ch].
4492 * Added `servername' field to the SilcClientEntry in the server
4493 to hold the name of the server where client is from. Affected
4494 file is silcd/idlist.h.
4496 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Moved the channel message encrypting in the router betwen
4499 router connections from silc_server_channel_message to the
4500 silc_server_packet_relay_to_channel since we want to check
4501 whether we have anybody channel before encrypting anything.
4502 Affected files silcd/packet_[receive/send].c.
4504 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Fixed the [AdminConnection] server config section to support
4507 multiple entries. Affected file silcd/serverconfig.c.
4509 * Added support into the server to check the validity of the
4510 incoming connection before executing any KE or authentication
4513 * The connection configuration is now saved to the KE and
4514 connection auth protocol contexts and not fetched anymore in
4515 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4517 * The local hosts listenning address and port is also resolved
4518 now when starting the server. We want to have the socket object
4519 to include the real address and port for the listener. Added
4520 new function silc_net_check_local_by_sock into the files
4521 lib/silcutil/silcnet.[ch].
4523 * Fixed a broadcast bug in server -> do not broadcast if we
4526 * Fixed a routing bug. Do not route broadcast packets ever.
4527 Broadcast packets must be processed always and not routed since
4528 they may be destined to some other host than yourself and thus
4529 would get routed without no good reason. Affected file is
4532 * Added function silc_server_config_is_primary_route to check
4533 whether primary router connection has been configured (a router
4534 configuration that we are initiating). If there is not, we
4535 will assume that there is only two routers in the SILC network
4536 and we will use the incoming router connection as our primary
4537 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4539 * Changed the order of the broadcasting. Broadcast _after_ the
4540 packet has been processed not before. Affected file is
4543 * Fixed a [ClientConnection] parsing bug. The port was never
4544 parsed correctly thus resulting to port 0. Affected file
4545 silcd/serverconfig.c.
4547 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4548 argument and did not set the broadcast packet flag. Affected
4549 file silcd/packet_send.c. Fixed same bug in the function
4550 silc_server_send_notify as well.
4552 * If we receive NEW_ID packet for our own ID in the server, ignore
4555 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Removed the nickname from the Private Message Payload.
4560 Updated the code and the protocol specs.
4562 * Updated protocol specs for submitting to the IETF.
4564 * Tweaked the Random Number Generator a bit. Affected file
4565 lib/silccrypt/silcrng.c. Exported a new function
4566 silc_rng_[global]_add_noise which can be used to add more
4569 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Do not parse packets with different timeout when protocol
4572 is active -> may cause problem with rekey. Affected file
4575 * When server receives signoff notify it must not create
4576 new channel key if the client is on any channels since the
4577 sender of the signoff notify will create it.
4579 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added printing of error messages during SKE protocol from the
4582 failure packet sent by server during SKE. Affected file
4585 * Removed the client's failure_callback handling with timeout
4586 and handle it immediately when received.
4588 * The SKE library returned wrong type in SUCCESS and FAILURE
4589 packets. They must be 32 bit MSB not 16 bit MSB.
4591 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Ok, rewrote the logic of the re-key and now it seems to work.
4594 I tested it on high traffic with frequent re-keys without
4595 problems. Added hmac_receive (and renamed hmac to hmac_send)
4596 in SilcClientConnection in lib/silcclient/client.h and
4597 in SilcIDListData in silcd/idlist.h. Also, removed the
4598 SilcPacketParserContext's cipher and hmac fields as they are
4599 not needed anymore and actually caused some problems when
4600 the ciphers and hmac's changed underneath the packet parser.
4602 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * If re-key protocol is active then process the incoming packets
4605 synchronously since we must assure that icoming packets encrypted
4606 with the old key is processed before the new keys is set to
4607 use. This is true other packets than for REKEY packets.
4608 Affected file silcd/server.c. The same was done to client library
4609 as well, affected file lib/silcclient/client.c.
4611 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Fixed bug in client and server to accept the force send if
4614 the packet is send from silc_[server/client]_packet_process
4615 function. Otherwise the packets are never delivered, oops.
4617 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Disable force sending of packets when REKEY protocol is active.
4620 We must assure that no packet is sent directly when rekey is
4621 performed. All packets must be sent through packet queue.
4622 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4623 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4624 function is silc_[server/client]_packet_send_real to check
4627 * Replaced the SIM paths from example config files to
4628 /usr/local/modules. Also, make install creates now
4629 /usr/local/silc/logs directory to hold all the SILC server
4632 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Made the configure.in.pre work on Solaris. Patch by salo.
4636 * Made all ciphers compatible with non-x86 machines. Defined
4637 CBC mode macros into lib/silccrypt/ciphers_def.h.
4639 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Fixed the make install.
4643 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * When MAC computation fails the silc_packet_decrypt returned 0
4646 even though it was supposed to return -1. Fixed this. The
4647 affected file is lib/silccore/silcpacket.c.
4649 * Do not replace the config files in /etc/silc (in make install)
4650 if they already exist. Affected file ./Makefile.am.
4652 * Do not send re-key packets immediately but through packet queue.
4653 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4655 * Changed silc_net_check_host_by_sock to return FALSE if the
4656 IP/DNS could not be resolved. Though, it returns the IP address
4657 now even if it could not resolve it (but returns also FALSE).
4658 Affected file lib/silcutil/silcnet.[ch].
4660 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Added silc_pkcs_decode_identifier to decode the public key's
4663 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4664 Added also silc_pkcs_free_identifier. Added also new context
4665 SilcPublicKeyIdentifier.
4667 * Added -S option to the silc client. It is used to dump the
4668 contents of the specified public key file.
4670 * Changed the PKCS api to return the public key length when
4671 setting the public key.
4673 * Fixed a fatal bug in the public and private key file loading.
4674 Affected file lib/silccrypt/silcpkcs.c.
4676 * Execute the packet parsing for client with zero (0) timeout
4677 if the protocol is active. Affected file silcd/server.c.
4679 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Made the key generation options to the silcd program. Added
4682 -C option, equivalent to client's option.
4684 * Added new [ServerKeys] config section to the server. It
4685 configures the server's public and private key.
4687 * Defined generic Public Key Payload into the protocol
4688 specification to send specific type of public keys and
4691 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4692 public key or certificate.
4694 * Implemented the GETKEY command to the server and to the
4695 client library and on user interface.
4697 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Made preliminary `make install' work.
4701 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added SilcServerRekey context into silcd/idlist.h.
4705 * Added the PFS support as defined in the specification to the
4706 SKE protocol. Affected files lib/silcske/*.c.
4708 * Added `ske_group' field to the SilcServerRekey context to hold
4709 the number of the SKE group that is used with PFS in re-key.
4710 Affected file silcd/idlist.h.
4712 * Added PFS re-key support to the server. Affected file is
4715 * Added silc_protocol_cancel to cancel execution of the next
4716 state of the protocol. Affected file is
4717 lib/silccore/silcprotocol.[ch].
4719 * Added the re-key support with and without PFS to the client
4720 library. Re-key is performed once in an hour, by default.
4722 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4723 Added silc_client_rekey_callback and silc_client_rekey_final.
4724 Affected files are lib/silcclient/protocol.[ch] and
4725 lib/silcclient/client.[ch].
4727 * Removed the `hmac_key' and `hmac_key_len' fields from the
4728 SilcClientConnection structure; not needed. Affected file is
4729 lib/silcclient/client.h.
4733 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Do not ask whether user wants to use the negotiated private key
4736 for private messages, just use it. Affected file is
4737 silc/local_command.c.
4739 * Added `send_enc_key' and `enc_key_len' fields to the
4740 SilcIDListData structure since they are needed in the re-key
4741 phase. Affected file is silcd/idlist.[ch].
4743 * Implemented the simple re-key protocol into the server.
4744 Affected files silcd/server.c and silcd/protocol.[ch]. The
4745 re-key will be performed once in an hour, by default.
4747 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4748 Added silc_server_rekey, silc_server_rekey_callback and
4749 silc_server_rekey_final.
4751 * Removed Tunneled flag from the protocol. Updated the code
4752 and the specifications.
4754 * Adde `pfs' field to the SilcIDListData to indicate whether
4755 the PFS is to be performed in the re-key. Affected file is
4758 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4761 int64 of at least the xintXX size. If void * is less that 4
4762 bytes uint32 * will be used. Defined bool as boolean.
4764 * Changed _ALL_ unsigned long and unsigned int to uint32,
4765 unsgined short to uint16 in the source tree.
4767 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4768 not handle clients that has entry->data.registered == FALSE.
4769 They are not in the network anymore. Affected file is
4772 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Implemented the sending of the SERVER_SIGNOFF notify in the
4775 server. Affected file is silcd/server.c.
4777 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4778 Added also silc_notify_payload_encode_args into the
4779 lib/silccore/silcnotify.[ch].
4781 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4782 Affected file silcd/packet_receive.c.
4784 * Implemented the SERVER_SIGNOFF notify handling in the client
4785 library. Affected file lib/silcclient/client_notify.c. Also,
4786 implemnted the printing of the SERVER_SIGNOFF info to the
4787 application. Affected file silc/client_ops.c.
4789 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4790 if the deleting was successful. Affected file silcd/idlist.[ch].
4792 * Added support for public key authentication in the connection
4793 authentication protocol in the client library. Affected file
4794 lib/silcclient/protocol.c.
4796 * Changed the server's silc_idlist_get_clients_by_* interface
4797 to support already allocated array so that new entries may be
4798 added to pre-allocated array. Affected file silcd/idlist.[ch].
4799 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4800 and command replies.
4802 * All command reply functions in the server now calls the
4803 pending command callback even if error occured. This way the
4804 error will be delivered to the client as well. Affected files
4805 silcd/command.c and silcd/command_reply.c.
4807 * Fixed INFO command to return local server's info if no server
4808 was provided. Affected file lib/silcclient/command.c.
4810 * Removed RESTART command for good. Updated the code and the
4813 * Rewrote parts of the task system. It is a bit simpler now.
4814 Removed unsued task priorities. The affected files are
4815 lib/silcutil/silctask.[ch].
4817 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Moved the USERS printing from the library to the application.
4820 Affected files lib/silcclient/command.c and silc/client_ops.c.
4822 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Added channel key re-key support. The re-key is perfomed
4827 only by the router and is done once in an hour. Added `rekey'
4828 field to the SilcChannelEntry in the server. Affected files
4829 silcd/server.c and silcd/idlist.h.
4831 * Added silc_task_unregister_by_context into the file
4832 lib/silcutil/silctask.[ch].
4834 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added SILC_UMODE_GONE mode to indicate when the client is not
4837 present in the SILC network. Added also support to the local
4838 command AWAY that will set this mode. Added support of showing
4839 "xxx is gone" in WHOIS command. The USERS command shows the
4840 gone status as well.
4842 * Fixed setting server and router operator privileges in the
4843 server's UMODE command. Affected file silcd/command.c.
4845 * Merged the SKE KE1 and KE2 payloads into one payload. The
4846 new KE payload is equivalent to the old KE2 payload.
4848 Cleaned up the SKE Start Payload parsing. It now uses the
4849 simple buffer unformatting to do the parsing. A lot faster
4852 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4853 to the SKE that is used to indicate whether both of the SKE
4854 parties should perform authentication. By default only the
4855 responder performs authentication. By setting this flag also
4856 the initiator must do authentication. By default it is unset
4857 since in normal SKE case, client to server connection, only
4858 the responder should do authentication. When doing SKE between
4859 two clients both should perform authentication. Updated the
4860 code and the protocol specs.
4862 * A little fix to IDENTIFY command in the server. Search the
4863 client first by hash not nickname. Affected file is
4866 * Fixed the silc_client_close_connection to support closing
4867 the client to client connections wihtout deleting too much
4868 data. Affected file lib/silcclient/client.c.
4870 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4871 are received if protocol used to be active but is not anymore
4872 the application would crash due to NULL pointer dereference.
4873 Affected files silcd/server.c and lib/silcclient/client.c.
4875 * Added `hash' field to the SilcClientConnection to include
4876 the hash function negotiated in the SKE protocol.
4878 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4879 to set the channel founder authentication data. A client can
4880 claim the founder rights later by providing the authentication
4881 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4882 This way the channel founder can regain the channel founder
4883 privileges even it is left the channel. This works only on
4884 local server and the client must be connected to the same
4885 server to be able to regain the founder rights. Updated the
4886 protocol specs accordingly.
4888 Added support to the CMODE command in the client to set the
4889 founder auth data. Read the README to see how to set it.
4891 Added support to the CUMODE command to claim the founder
4892 rights. Read the README to see how to do it.
4894 Added support for the founder authentication to the Channel
4895 Entry in the server. Affected file silcd/idlist.h.
4897 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4898 server's CMODE command. Affected file silcd/command.c.
4900 * Added the following new functions into lib/silccore/silcauth.[ch]:
4901 silc_auth_get_method and silc_auth_get_data.
4903 * The server now saves the remote hosts public key to the
4904 SilcIDListData pointer. Affected file silcd/protocol.c.
4906 * The normal server now does not remove the channel entry from
4907 the cache if the founder authentication data is set. It used
4908 to remove it if the founder was the last one on the channel on
4909 the server and left the channel. The auth data is saved and
4910 if the channel is re-joined later the old entry is used with
4911 the old auth data. Affected files silcd/command_reply.c and
4914 * Removed the `pkcs' field from the SilcIDListData structure
4915 in the server; it is not used. Affected file silcd/idlist.h.
4917 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Fixed packet processing on slow links. Partial packets were
4920 never re-processed because the incoming data buffer was cleared
4921 by the application. Application must not directly clear the
4922 sock->inbuf, the packet processing routines handle it. Fixed
4923 this in client library and in server.
4925 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Fixed the WHOIS and IDENTIFY send reply function to really
4928 check whether to send list or just one entry. Affected file
4931 * Cleaned up the LEAVE command's channel key distribution. The
4932 affected file silcd/command.c.
4934 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4935 can enforce the channel mode as well. In that case the ID
4936 includes the ID of the server. The code now enforces the
4937 mode change if the router have different mode than the server.
4939 * The notify client operation with CMODE_CHANGE notify can now
4940 return NULL client_entry pointer if the CMODE was not changed
4941 by client. Application must check for this.
4943 * Added <Server ID> argument to INFO command to support server
4944 info fetching by Server ID.
4946 * Added silc_server_announce_get_channel_users to get assembled
4947 packets of channel users of the specified channel. Affected
4948 file silcd/server.[ch].
4950 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4951 was freed underneath the ID Cache.
4953 * Re-announce clients when the server received CHANNEL_CHANGE
4954 notify from the router. Affected file silcd/packet_send.c.
4956 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4959 crashed since it did not handle the fact that there is no cipher
4960 called "3" and didn't check the error condition. Now fixed.
4962 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4963 flag. It can be used to send message requests.
4965 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Implemented the RESTART command in the client.
4969 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4970 notice type messages. Added notice printing to the user
4973 * The channel keys are not re-generated if the channel's mode
4974 is PRIVKEY, ie private key on the channel exists. Affected
4975 files silcd/server.c and silcd/command.c.
4977 * Fixed a little bug in channel message delivery when channel
4978 private keys are set in the server. Affected file is
4979 silcd/packet_send.c.
4981 * Changed the setting on channel->on_channel = TRUE from the
4982 silc_client_save_channel_key to the JOIN command reply. The
4983 key payload is not received if the private channel key is set.
4984 Affected file lib/silcclient/command_reply.c and the
4985 lib/silcclient/client_channel.c.
4987 * When the CMODE_CHANGE notify is sent and the channel private
4988 key mode is removed the channel key must be re-generated in
4989 other cells as well. Added this support for the router in the
4990 silcd/packet_receive.c.
4992 * Added new local command NOTICE to send notice message on
4993 channel. Affected file silc/local_command.[ch].
4995 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added new local command ME to the client. It is used to send
4998 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4999 some action. Affected file silc/local_command.[ch].
5001 * Changed channel_message and private_message client operations
5002 to deliver the message flags to the application. Added also
5003 the `flags' arguments to the silc_client_send_channel_message
5004 and silc_client_send_private_message functions. Affected file
5007 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Redefined the Private Message Payload to support private message
5010 keys and to support the new private message flags. Updated
5011 the protocol specs. Flags makes it possible to have for example
5012 CTCP style messages.
5014 * Added new type SilcPrivateMessagePayload and defined an API
5015 for it in the lib/silcclient/silcprivate.[ch].
5017 * Tested private message private keys successfully. Tested the
5018 private message key set, unset and list commands with the new
5021 * Redefined the Channel Message Payload to include the channel
5022 message flags (equal with private message flags) to support
5023 for example CTCP style messages.
5025 * Defined some of the message (for channel and private message)
5026 flags. Updated the protocol specs and added the flags to the
5027 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5029 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * Added SilcKeyAgreementStatus type to the key agreement routines
5032 to indicate the current status and error if one occured.
5033 The status types are defined in the lib/silcclient/silcapi.h.
5035 * Added new local command KEY that is used to set and unset private
5036 keys for channels, set and unset private keys for private messages
5037 with remote clients and to send key agreement requests and
5038 negotiate the key agreement protocol with remote client. The
5039 key agreement is supported only to negotiate private message keys,
5040 it currently cannot be used to negotiate private keys for channels,
5041 as it is not convenient for that purpose.
5043 * Fixed a minor pending callback setting bug in the function
5044 silc_client_get_client_by_id_resolve, now the function works.
5045 Affected file lib/silcclient/idlist.c.
5047 * Added function silc_net_get_local_port to get local bound
5048 port by socket. Added to lib/silcutil/silcnet.[ch].
5050 * Added `sockets' and `sockets_count' fields to the SilcClient
5051 object. They hold the sockets of the listenning sockets in
5052 the client. Listenning sockets may be for example the key
5053 agreement server. Affected file lib/silcclient/client.[ch].
5054 Added functions the silc_client_add_socket and the
5055 silc_client_del_socket. They are exported to the application
5058 * Added ~./silc/clientkeys to support other client's public keys.
5060 * Renamed verify_server_key client operation to verify_public_key
5061 and added one argument to indicate the type of the connection
5062 (server, client etc.).
5064 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Added silc_server_connection_auth_request to handle the
5067 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5068 silcd/packet_receive.[ch].
5070 * Added silc_server_send_connection_auth_request into the
5071 silcd/packet_send.c to send the connection auth request packet.
5073 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5076 * Fixed the public key authentication in responder side in the
5077 server. The `auth_data' pointer includes the SilcPublicKey
5078 not the path to the public key. Affected file silcd/protocol.c.
5080 * Implemented the public key authentication in the initiator side
5081 in the server. Affected file silcd/protocol.c.
5083 * Removed the [RedirectClient] config section from the server
5084 configuration. Is not needed and I don't want to implement it.
5086 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Cleaned up the CMODE command in the server. It now works
5089 correctly and supports all the modes defined in the protocol.
5090 Affected file is silcd/command.c.
5092 * Added `hmac_name' field to the SilcChannelEntry in the server
5093 to hold the default HMAC of the channel. It can be set when
5094 creating the channel (with JOIN command). Affected files
5097 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5098 type to indicate the change of the current cipher and hmac
5099 on the channel. Client can safely ignore the <cipher> argument
5100 (if it chooses to do so) since the CHANNEL_KEY packet will
5101 force the channel key change anyway. The <hmac> argument is
5102 important since the client is responsible of setting the new
5103 HMAC and the hmac key into use.
5105 * Fixed the CMODE command in the client library as well.
5107 * Tested CMODE command in router environment successfully.
5109 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Show the version of the remote client (or server) when connecting
5112 to the server. It is logged to the log file. Affected file
5113 is silcd/protocol.c.
5115 * Fixed the KILLED notify handling in the client library. The
5116 client must be removed from all channels when receiving the
5119 Also, do not remove the client entry when giving the KILL
5120 command but when the KILLED notify is received.
5122 * Removed silc_idlist_find_client_by_nickname from the server.
5123 Not needed anymore. Affected files silcd/idlist.[ch].
5125 * Implemented the CHANNEL_CHANGE notify type handling to the
5126 server. Affected file silcd/server.c.
5130 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Added silc_server_send_notify_invite to send the INVITE
5133 notify between routers.
5135 * Implemented the INVITE command correctly to the server.
5137 * Implemented the INVITE notify type handling in the server.
5139 * Implemented the INVITE command to the client library and on the
5142 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added function silc_server_get_client_resolve to find the
5145 client entry by ID from all ID lists and then resolve it
5146 (using WHOIS) if it cannot be found. Affected file is
5149 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Implemented the BAN command to the client library.
5153 * The JOIN command in the server now checks the invite list
5156 * Changed the silc_command_reply_payload_encode_va and the
5157 silc_command_payload_encode_va to support that if argument is
5158 NULL it ignores and checks the next argument. Affected file
5159 lib/silccore/silccommand.c.
5161 * Added silc_server_send_notify_ban to send the BAN notify
5162 type between routers.
5164 * Chaned the silc_notify_payload_encode to support that if
5165 argument is NULL it ignores and checks the next argument.
5166 Affected file lib/silccore/silcnotify.c.
5168 * Tested ban lists in router environment successfully.
5170 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Implemented BAN command to the server, in silcd/command.[ch].
5174 * Removed the BAN and INVITE_LIST modes from the CMODE command
5177 * Added function silc_string_match to regex match two strings.
5178 Affected files lib/silcutil/silcutil.[ch].
5180 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Redefined parts of the SilcChannelEntry in the server to support
5183 the new ban and invite lists.
5185 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * Redefined the INVITE command. The same command can be used to
5188 invite individuals to the channel but also to manage the invite
5189 list of the channel (to add to and remove from the invite list).
5190 Updated the protocol specs.
5192 * Added new command SILC_COMMAND_BAN that can be used to manage
5193 the ban list of the channel. Updated the protocol specs.
5195 * Removed the channel modes: the SILC_CMODE_BAN and the
5196 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5197 in the CMODE command. The equivalent features are now available
5198 using INVITE and BAN commands. Updated the protocol specs.
5200 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5201 in the network about change in the current ban list. The notify
5202 type is not used by the client.
5204 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5205 support the invite lists.
5207 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added new function silc_string_regexify that converts string
5210 including wildcard characters into regex string that can
5211 be used by the GNU regex library. Added into the file
5212 lib/silcutil/silcutil.[ch].
5214 Added silc_string_regex_combine to combine to regex strings
5215 into one so that they can be used as one regex string by
5216 the GNU regex library. Added into the file
5217 lib/silcutil/silcutil.[ch].
5219 Added silc_string_regex_match to match two strings. It returns
5220 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5222 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Imported GNU regex to the soruce tree into lib/contrib.
5225 Fixed some compiler warning from the regex.c.
5227 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Fixed MOTD command in the server to work in router environment.
5231 * Fixed the MOTD command in the client library to support
5232 the server argument in the command.
5234 * Added `nickname_len' argument to the silc_idlist_add_client
5235 in the server, as the `nickname' argument may be binary data
5238 * Added silc_idlist_get_channels to return all channels from
5241 * Implemented LIST command to the server. Affected file is
5244 * Implemented the LIST command to the client library and on the
5247 * Added [<user count>] argument to the LIST command reply.
5248 With private channels the user count is not shown.
5250 * Updated TODO and README.
5252 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * The client entry's data.registered must be TRUE even with
5255 global client entry on global client list. The data.registered
5256 is used to check whether the client is anymore in the network,
5257 for example with WHOWAS command so it must be valid.
5259 * Fixed the WHOWAS command in the server. It now actually works
5260 in router environment. Added function into silcd/command_reply.c
5261 silc_server_command_reply_whowas_save.
5263 * Added silc_idlist_purge function to the silcd/idlist.c
5264 to periodically purge the ID Cache.
5266 * Fixed INFO command in the server. It works now in router
5267 environment. Added <server name> argument to the INFO command
5268 reply. Updated the protocol specs.
5270 * Fixed minor bug in silc_idcache_purge to not purge if the
5271 expire value is zero.
5273 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5274 they were buggy because of the WHOWAS information.
5276 * Fixed local command MSG to handle the async resolving of
5277 the remote client properly. It used to fail the first MSG.
5278 Affected file silc/local_command.c.
5280 * Added `data_len' field to SilcIDCache context.
5282 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Update TODO. Todo in commands in the server.
5286 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5289 used by routers as broadcast packet to inform other routers
5290 about the changed user mode.
5292 Implemented the notify handling in the server. Affected file is
5293 silcd/packet_receive.c. Added the function
5294 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5296 * Added new generic Channel Payload and deprecated the New Channel
5297 Payload. The New Channel Payload is now the generic Channel
5300 * Added new argument `mode' to the silc_server_send_new_channel
5301 as it is required in the Channel Payload now.
5303 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5304 and created a new and real SilChannelPayload to represent the
5305 new generic Channel Payload. Implemented the encode/decode
5306 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5308 * Added silc_server_get_client_channel_list to return the list
5309 of channels the client has joined for WHOIS command reply.
5310 Affected file silcd/server.[ch].
5312 * Implemented the channel list sending in the WHOIS command reply
5313 in server and in the client.
5315 Implemented the channel list displaying on the user interface
5316 as well. Affected file silc/client_ops.c.
5318 * Added silc_channel_payload_parse_list to parse list of Channel
5319 Payloads. It returns SilcDList list of SilcChannelPayloads.
5320 Client for example can use this function to parse the list of
5321 channels it receives in the WHOIS command reply. The caller
5322 must free the list by calling silc_channel_payload_list_free.
5323 Affected files lib/silccore/silcchannel.[ch].
5325 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Added one new argument <user mode> to the WHOIS command reply
5328 to return the mode of the user in SILC. Updated the protocol
5331 Implemented it to the server and client.
5333 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * Fixed the mode printing on the user interface on joining.
5336 Affected file silc/client_ops.c.
5338 * Implemented the UMODE command and user modes in general to the
5339 client library and to the user interface.
5341 * Implemented the UMODE command to the server.
5343 * The server now sends UNKNOWN_COMMAND error status if client sends
5344 unknown command. Affected file silcd/command.c.
5346 * All server commands now handle the command identifier the right
5347 way when sending the command reply to the client. The client can
5348 use to identify the command replies with the identifier.
5350 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added silc_server_get_client_route to resolve the route to
5353 the client indicated by the client ID. Affected file is
5356 * Added silc_server_relay_packet as general function to relay
5357 packet to arbitrary destination. This deprecates functions
5358 like _send_private_message_key, _relay_notify etc. Affected
5359 file is silcd/packet_send.[ch].
5361 Removed silc_server_send_key_agreement,
5362 silc_server_send_private_message_key and
5363 silc_server_packet_relay_notify functions from the file
5364 silcd/packet_send.[ch].
5368 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5369 server. Affected file silcd/packet_receive.[ch].
5371 * Implemented the KILL command to the client. Implemented the
5372 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5373 Affected files lib/silcclient/command[_reply].c and
5374 lib/silcclient/client_notify.c. Implemented the KILL notify
5375 printing in the user inteface.
5377 * Fixed a lot silc_parse_nick memory leaks from the client
5378 library in the file lib/silcclient/command.c.
5380 * Changed the silc_server_send_notify_on_channels's `sender'
5381 argument from SilcSocketConnection to SilcClientEntry to
5382 check the sender as entry and not as connection object and not
5383 to send to the client provided as argument. The affected file
5384 is silcd/packet_send.[ch].
5386 * The notify packets that are destined directly to the client used
5387 to not to be processed by the server. Now changed that and the
5388 server processes all notify packets. After relaying the packet
5389 to the client the notify packet is processed in the server.
5391 * The silc_server_free_client_data now checks whether there is
5392 pending outgoing traffic for the client and purges the data to
5393 the network before removing the client entry.
5395 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5398 an client is killed from the SILC Network. Updated the protocol
5401 Added new function silc_server_send_notify_killed to the
5402 silcd/packet_send.[ch].
5404 * Added function silc_server_packet_relay_notify to relay notify
5405 packets that are destined directly to a client. In this case
5406 the server does not process the notify packets but merely relays
5407 it to the client. Affected file silcd/packet_send.[ch].
5409 Added also silc_server_packet_process_relay_notify to check
5410 whereto relay the notify. Affected file is
5411 silcd/packet_receive.[ch].
5413 * Implemented the KILL command to the server.
5417 * Added the backup schema desgined last fall to the protocol
5418 specs for everyone to see. The specification is in the
5419 *-spec-xx.txt draft and the packet type definitions for the
5420 backup routers is in *-pp-xx.txt draft. Thusly, added also
5421 new packet type SILC_PACKET_CELL_ROUTERS.
5423 * A big security problem in the implementation discovered. The
5424 signoff of an client did not cause new channel key generation
5425 which it of course should've done. The channel keys must be
5426 always re-generated when client leaves (or signoffs) the channel.
5427 The silc_server_remove_from_channels funtion now handles
5428 the channel key re-generation.
5430 * Added `sender' argument to the silc_server_send_notify_on_channels
5431 to not to send the client provided as argument. Affected file
5432 silcd/packet_send.[ch].
5434 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Implemented OPER and SILCOPER commands into the server and
5439 * Added silc_auth_verify and silc_auth_verify_data to verify
5440 the authentication directly from the authentication payload.
5441 It supports verifying both passphrase and public key based
5442 authentication. Affected file lib/silccore/silcauth.[ch].
5444 * Added `hash' field to the SilcIDListData structure. It is the
5445 hash negotiated in the SKE protocol. Affected file is
5448 * Slight redesigning of the SilcAuthPayload handling routines.
5449 Do not send SilcPKCS but SilcPublicKey as argument.
5451 * Implemented the public key authentication support to the
5452 serverconfig. The public key is loaded from the provided path
5453 and saved as authentication data to void * pointer. Thus,
5454 changed the unsigned char *auth_data to void *auth_data;
5456 * Fixed SHUTDOWN command to send the reply before the server
5457 is shutdown. :) Affected file silcd/command.c.
5459 * Fixed fatal bug in CONNECT command. The hostname was invalid
5460 memory and server crashed. Affected file silcd/command.c.
5462 * Fixed fatal bug in CLOSE command. The server_entry became
5463 invalid but was referenced later in the command. Affected file
5466 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Fixed fatal bug in failure packet handling. Server ignored
5469 the failure and thus crashed when it came.
5473 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5476 that the command may be executed only once in (about) 2 seconds.
5477 The old SILC_CF_LAG flag is same but allows command bursts up
5478 to five before limiting.
5480 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5481 server code. Various commands now includes the CF_LAG_STRICT
5482 flag to disallow any kind of miss-use of the command.
5484 * Fixed the silc_buffer_unformat to not to allocate any data
5485 if the length of the data is zero. It used to allocate the
5486 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5488 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Changed the format of AdminConnection configuration section
5491 in the server. Added username of the admin to the format.
5492 Affected files silcd/serverconfig.[ch].
5494 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5495 to return admin configuration data by host, username and/or
5498 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Implemented WHOWAS command to the server. Added the functions:
5502 silc_server_command_whowas_parse,
5503 silc_server_command_whowas_send_reply,
5504 silc_server_command_whowas_from_client and
5505 silc_server_command_whowas_from_server
5507 * Added <Client ID> argument to the WHOWAS command reply. Updated
5508 the protocol specs accordingly.
5510 * Implemented WHOWAS command and command_reply to the client
5513 Implemented the WHOWAS printing on the user interface.
5515 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added new argument to the WHOWAS command reply, the real name.
5518 It is an optional argument. Updated the protocol specs.
5520 * Added SilcIDCacheDestructor callback that is registered when
5521 the SilcIDCache is allocated. The callback is called when
5522 an cache entry in the ID Cache expires, or is purged from the
5523 cache. Added into lib/silccore/idcache.[ch].
5525 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5526 to destruct the client entries when the cache entry expires.
5527 Other ID Cache's in server and in the client library ignores
5530 * If the ID Cache entry's `expire' field is zero then the entry
5531 never expires. Added boolean `expire' argument to the
5532 silc_idcache_add function in the lib/silccore/idcache.[ch].
5533 If it is TRUE the default expiry value is used.
5535 * Added silc_server_free_client_data_timeout that is registered
5536 when client disconnects. By default for 5 minutes we preserve
5537 the client entry for history - for WHOWAS command.
5539 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Added support to the server to enforce that commands are not
5542 executed more than once in 2 seconds. If server receives
5543 commands from client more frequently, timeout is registered
5544 to process the commands. Affected file silcd/command.c.
5545 Added new function silc_server_command_process_timeout.
5547 * Changed NICK_NOTIFY handling in client library to check that
5548 if the client's nickname was changed, so there is no need to
5549 resolve anything from the server.
5551 * Removed error printing from the WHOIS and IDENTIFY commands.
5552 If error occurs then it is ignored silently in the client library.
5553 The application, however, may map the received error to
5554 human readable error string. The application currently maps
5555 the NO_SUCH_NICKNAME error to string.
5557 * Made the command status message public to the application. Moved
5558 them from lib/silcclient/command_reply.c to
5559 lib/silcclient/command_reply.h. The application can map the
5560 received command status to the string with the
5561 silc_client_command_status_message function.
5563 * Added check to the server to check that client's ID is same
5564 as the Source ID in the packet the client sent. They must
5567 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Added dist-bzip hook to the Makefile.am to make bzip2
5570 compressed distributions.
5572 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Server now enforces the maximum length for the nickname and
5575 the channel as protocol specification dictates. 128 bytes for
5576 nickname and 256 bytes for channel name.
5578 * Moved the WHOIS printing to the application. The client libary
5579 does not print out the WHOIS information anymore, the application
5580 must do it. Renamed silc_client_command_reply_whois_print to
5581 the silc_client_command_reply_whois_save.
5583 The client's idle time is also sent to the application now, and
5584 the idle is shown on screen.
5586 * Added silc_client_command_reply_identify_save to save the
5587 received IDENTIFY entries.
5589 * Do not check for channel private keys in message sending and
5590 reception if the channel does not have the PRIVKEY mode set.
5591 Affected file lib/silclient/client_channel.c.
5593 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5596 just surfaced after chaning the JOIN procedure.
5598 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added silc_client_get_clients_by_list to get client entries
5601 from Client ID list, that is returned for example by JOIN
5602 and USERS command replies. The application should use this
5603 function for example when JOIN command reply is received to
5604 resolve the clients already on the channel (library does not
5605 do that anymore as USERS command reply is not used in the JOIN
5606 procedure anymore). Affected files lib/silcclient/silcapi.h and
5607 lib/silcclient/idlist.c.
5609 * JOIN command reply and USERS command reply returns now SilcBuffer
5610 pointers instead of unsigned char pointers when returning
5611 the client list and mode list.
5613 * Added <Client ID> argument to the JOIN command reply, mainly
5614 for the server to identify for which client the command was
5615 originally sent. Updated protocol specs accordingly.
5617 * Added SilcDlist private_key pointer to the SilcChannelEntry
5618 in the client to support the channel private keys. Affected
5619 file is lib/silcclient/idlist.h.
5621 * Added SilcChannelPrivateKey argument to the function
5622 silc_client_send_channel_message so that application can choose
5623 to use specific private ke if it wants to. If it is not provided,
5624 the normal channel key is used, unless private keys are set.
5625 In this case the first (key that was added first) is used
5626 as the encryption key.
5628 * Implemented the support for channel private key handling.
5629 Implemented the following functions:
5631 silc_client_add_channel_private_key,
5632 silc_client_del_channel_private_keys,
5633 silc_client_del_channel_private_key,
5634 silc_client_list_channel_private_keys and
5635 silc_client_free_channel_private_keys
5637 Affected file lib/silcclient/client_channel.c.
5639 * Added the support for the private keys in the channel message
5640 sending and encryption and in the message reception and
5641 decryption. Affected funtions are
5642 silc_client_send_channel_message and silc_client_channel_message.
5644 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Added SKE's key verify callback to the client library's
5647 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5649 * Removed the statement that server (or router) must send USERS
5650 command reply when joining to the channel so that the client
5651 knows who are on the channel. Instead, the client list and
5652 client's mode list is now sent in the JOIN command reply to the
5653 client who joined channel. This is better solution.
5655 * Added function silc_server_get_users_on_channel and function
5656 silc_server_save_users_on_channel to the silcd/server.[ch].
5658 * Removed function silc_server_command_send_users from the
5661 * Do not show topic on the client library anymore. The topic is
5662 sent in the command reply notify to the application and the
5663 application must show the topic now.
5665 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added client searching by nickname hash into the IDENTIFY and
5668 WHOIS commands in the server as they were clearly missing from
5669 them. Affected file is silcd/command.c.
5671 * Fixed a bug in private message receiving in the client library.
5672 The remote ID was freed and it wasn't supposed, now it is
5675 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Minor fix to the channel payload; allocate the data area, as it
5678 needs to be of specific length.
5680 * If the key agreement port is zero then the operating
5681 system will define the bound port. Affected files are
5682 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5684 * Added new function silc_channel_payload_decrypt into the file
5685 lib/silccore/silcchannel.[ch].
5687 * Moved the channel message etc, check from silc_packet_decrypt
5688 to applications. The library calls now a generic
5689 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5690 when the packet is either normal or special. This was done to
5691 allow more wide range of checking that was not allowed when
5692 the code was in library. Now applications can do virtually any
5693 checks to the packet and return to the library the decision how
5694 the packet should be processed. Affected files are
5695 lib/silccore/silcpacket.[ch].
5697 Added silc_server_packet_decrypt_check to the server and
5698 silc_client_packet_decrypt_check to the client library.
5700 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5701 to send with specified source and destination information.
5703 * Channel message delivery between routers was broken after the
5704 channel key distribution was fixed earlier. The channel key
5705 was used be to distributed to other routers as well which is not
5706 allowed by the protocol. Now this is fixed and channel keys
5707 really are cell specific and the channel message delivery between
5708 routers comply with the protocol specification.
5710 * Fixed various commands in server to check also the global list
5711 for the channel entry and not just the local list. The affected
5712 file silcd/command.c.
5714 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added assert()s to buffer formatting and unformatting routines
5717 to assert (if --enable-debug) when error occurs. Affected
5718 file: lib/silcutil/silcbuffmt.c.
5720 * Changed to auto-reconnect to check whether the remote host is
5721 router and register the re-connect timeout if it is. It used
5722 to check that whether we are normal server, but router must do
5723 auto-reconnect with another router as well. Affected file
5726 * Removed the [<key len>] option from CMODE command as the cipher
5727 name decides the key length, nowadays. See the defined ciphers
5728 from the protocol specification.
5730 * Added [<hmac>] option to the CMODE command to define the HMAC
5731 for the channel. Added SILC_CMODE_HMAC channel mode.
5733 * Added [<hmac>] option for the JOIN command so that user can
5734 select which HMAC is used to compute the MACs of the channel
5737 * Added Hmac field to the Channel Message Payload. The integrity
5738 of plaintext channel messages are now protected by computing
5739 MAC of the message and attaching the MAC to the payload. The
5740 MAC is encrypted. Now, it is clear that this causes some
5741 overhead to the size of the packet but rationale for this is that
5742 now the receiver can verify whether the channel message decrypted
5743 correctly and also when private keys are set for the channel the
5744 receiver can decrypt the packet with several keys and check from
5745 the MAC which key decrypted the message correctly.
5747 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5748 lib/silccrypt/silccipher.[ch].
5750 * Added silc_hash_len to return the digest length into the
5751 lib/silcrypt/silchash.[ch].
5753 * Rewrote parts of Silc Channel Payload interface in the
5754 lib/silccore/silcchannel.[ch]. The encode function now also
5755 encrypts the packet and parse function decrypts it.
5757 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Fixed a minor formatting bug in the SKE's key material processing.
5760 It actually might have processed the keys wrong way resulting
5763 * Redefined the mandatory HMAC algorithms and added new algorithms.
5764 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5765 and hmac-md5 truncated to 96 bits. The mandatory is now
5766 hmac-sha1-96. Rest are optional (including the one that used
5767 to be mandatory). Rationale for this is that the truncated HMAC
5768 length is sufficient from security point of view and can actually
5769 make the attack against the HMAC harder. Also, the truncated
5770 HMAC causes less overhead to the packets. See the RFC2104 for
5773 * Added new [hmac] configuration section. The SKE used to use
5774 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5775 is of course wrong. The official names that must be proposed in
5776 the SKE are the ones defined in the protocol specification
5777 (hmac-sha1-96 for example). The user can configure any hmac
5778 using any hash function configured in the [hash] section. At
5779 least, the mandatory must be configured.
5781 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5783 * Added HMAC list to the SKE proposal list. It has now both
5784 hash algorithm list and HMAC list. This makes the protocol
5785 incompatible with previous versions. The SKE now seems to work
5786 the way it is supposed to work, for the first time actually.
5788 * Defined plain Hash algorithms to the protocol specification.
5791 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Implemented support for key agreement packets into the server.
5794 Added functions silc_server_key_agreement and
5795 silc_server_send_key_agreement. Other than these functions,
5796 server has nothing to do with this packet.
5798 * Added support for private message key packets into the server.
5799 Added functions silc_server_private_message_key and
5800 silc_server_send_private_message_key.
5804 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5805 called in the protocol's final callback instead in the END
5806 protocol state. This makes a little more sense and in the same
5807 time in client we can use the same protocol routines for normal
5808 key exchange and to key agreement packet handling as well.
5810 * Added to both client's and server's KE protocol context the
5811 SilcSKEKeyMaterial pointer to save the key material. We will
5812 bring the key material to the protocol's final callback by doing
5813 this. The final callback must free the key material.
5815 * Added SKE's packet_send callback into client's KE protocol
5816 context so that the caller can choose what packet sending function
5817 is used. This way we can use different packet sending when
5818 doing normal SKE when doing key agreement packet handling (in
5819 the key agreement packet handling we do not want to encrypt
5822 * Implemented the responder side of the key agreement routines
5823 in the client. The client can now bind to specified port and
5824 accept incoming key negotiation. The key material is passed
5825 to the application after the protocol is over.
5827 * Implemented the processing of incoming Key Agreement packet
5828 in the client. Added function silc_client_key_agreement to
5831 * Implemented the intiator side of the key agreement routines
5832 in the client. The client can now initiate key agreement with
5833 another remote client. The key material is passed to the
5834 application after the protocol is over.
5836 * Created client_keyagr.c to include all the key agreement
5839 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5840 SILC_TASK_CALLBACK except that it is not static.
5842 * Created client_notify.c and moved the Notify packet handling
5843 from the client.[ch] into that file.
5845 * Created client_prvmsg.c and moved all private message and
5846 private message key routines from the client.[ch] into that file.
5848 * Create client_channel.c and moved all channel message and
5849 channel private key routines from the client.[ch] into that file.
5851 * Changed silc_client_get_client_by_id_resolve to resolve with
5852 WHOIS command instead of IDENTIFY command, in the file
5853 lib/silclient/idlist.c.
5855 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Implemented the SKE's responder side to the Client library.
5859 * When FAILURE is received to the protocol do not trust it
5860 blindly. Register a timeout to wait whether the remote closes
5861 the connection as it should do it, only after that process the
5862 actual failure. This was changed to both client and server.
5864 * Added client_internal.h to include some of the structures
5865 there instead of client.h in lib/silcclient/.
5867 * Added function silc_task_unregister_by_callback to unregister
5868 timeouts by the callback function.
5870 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Some "Incomplete WHOIS info" errors has been appearing on the
5873 log files. Took away the entry->userinfo check from WHOIS
5874 reply sending. The entry->userinfo is now " " if client did not
5875 provide one. I thought this was fixed earlier but something
5876 is wrong still. Let's see if the error still appears.
5878 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Fixed a minor bug in the login when the channel key is
5881 re-generated in the server. It used to generate the key in
5882 wrong order and thus caused problems in the channel traffic.
5884 * Fixed a minor bug in channel key distsribution after
5885 KICK command. The key was not sent to the router even though
5888 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Added silc_ske_process_key_material_data as generic routine
5891 to process any key material as the SILC protocol dictates. The
5892 function is used by the actual SKE library but can be used by
5893 applications as well. This relates to the private message keys
5894 and the channel private keys since they must be processed the
5895 same way the normal SILC session keys. The protocol dictates
5896 this. Affected files: lib/silcske/silcske.[ch].
5898 Added also silc_ske_free_key_material to free the
5899 SilcSKEKeyMaterial structure.
5901 * Defined silc_cipher_set_key function to set the key for
5902 cipher without using the object's method function. The affected
5903 files: lib/silccrypt/silccipher.[ch].
5905 * Implemented silc silc_client_add_private_message_key,
5906 silc_client_add_private_message_key_ske,
5907 silc_client_del_private_message_key,
5908 silc_client_list_private_message_keys and
5909 silc_client_free_private_message_keys functions in the
5912 Added functions silc_client_send_private_message_key to send
5913 the Private Message Key payload and silc_client_private_message_key
5914 to handle incoming Private Message Key payload.
5916 * Added Cipher field to the Private Message Key payload to set
5917 the cipher to be used. If ignored, the default cipher defined
5918 in the SILC protocol (aes-256-cbc) is used.
5920 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Removed lib/silcclient/ops.h file.
5924 Redefined parts of the SILC Client Library API. Created new
5925 file silcapi.h that deprecates the ops.h file and defines the
5926 published Client Library API. Defined also private message key
5927 API and channel private key API into the file.
5929 This is the file that the application must include from the
5930 SILC Client Library. Other files need not be included by
5931 the application anymore.
5933 * Added new key_agreement client operation callback and also
5934 defined the Key Agreement library API for the application.
5936 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5939 is used by clients to request key negotiation between another
5940 client in the SILC network. If the negotiation is started it
5941 is performed using the SKE protocol. The result of the
5942 negotiation, the secret key material, can be used for example
5943 as private message key.
5945 Implemented the Key Agreement payload into the files
5946 lib/silccore/silauth.[ch].
5948 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Redefined ciphers for the SILC protocol. Added some new ciphers
5951 and defined the key lengths for the algorithms. Changed the
5952 code accordingly. The default key length is now 256 bits.
5954 * Fixed SKE key distribution function silc_ske_process_key_material
5955 when the key length is more than 128 bits. The default key
5956 length in SILC is now 256 bits.
5958 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5959 to indicate unsupported algorithm.
5961 * Renamed rijndael.c to aes.c and all functions as well.
5963 * Fixed a long standing channel key setting bug in client library.
5964 Weird that it has never surfaced before.
5966 * Fixed bug in channel deletion. If the entire channel is removed
5967 then it must also delete the references of the channel entry
5968 from the client's channel list as the client's channel entry and
5969 the channel's client entry share same memory.
5971 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Implemented CONNECT and SHUTDOWN commands in the client.
5975 * Implemented CLOSE command to the client.
5977 * Added the function silc_idlist_find_server_by_name into the
5978 files silcd/idlist.[ch].
5980 Added the function silc_idlist_find_server_by_conn into the
5981 files silcd/idlist.[ch].
5983 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * DIE command was renamed to SHUTDOWN. Updated the both code
5988 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5989 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5991 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5994 * Added function silc_server_create_connection function to create
5995 connection to remote router. My server implementation actually
5996 does not allow router to connect to normal server (it expects
5997 that normal server always initiates the connection to the router)
5998 so the CONNECT command is only good for connecting to another
6001 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6004 or some other client was kicked from the channel.
6006 Implemented the handling of the notify type to both client
6009 Implemented silc_server_send_notify_kicked to send the KICKED
6010 notify. It is used to send it to the server's primary router.
6012 * Implemented the KICK command into server and client.
6014 * Added `query' argument to the silc_idlist_get_client function
6015 to indicate whether to query the client from server or not if
6018 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6019 to indicate that the client is not channel founder.
6023 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Removed the rng context from SilcPacketContext structure and
6026 changed that the packet routine uses the Global RNG API.
6028 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Added support for quit message that client can "leave" on the
6031 channel when it quits the SILC. It is ditributed inside the
6032 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6034 Added silc_server_free_client_data that will take the
6035 signoff message as argument.
6037 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6039 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Updated parts of the protocol specification to keep it up
6044 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6047 payloads in one packet.
6049 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6050 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6051 use now the new List flag.
6053 * Also deprecated the following packet types: REPLACE_ID,
6054 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6056 * Added list support for Notify packet in server.
6058 * Added silc_server_send_notify_channel_change to send the
6059 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6060 the silc_server_send_replace_id.
6062 * Added silc_server_send_notify_nick_change to send the
6063 NICK_CHANGE notify type. Deprecates the function
6064 silc_server_send_replace_id.
6066 * Added silc_server_send_notify_join to send the JOIN notify type.
6067 Deprecates the function silc_server_send_new_channel_user.
6069 * Added silc_server_send_notify_leave to send LEAVE notify type.
6070 Deprecates the function silc_server_send_remove_channel_user.
6072 * Added silc_server_send_notify_cmode and
6073 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6074 types. Deprecates the silc_server_send_set_mode function.
6076 * Added SERVER_SIGNOFF notify type to indicate that server has
6077 quit. This means that all clients on the channel from that
6078 server will drop. This can be also used when netsplit happens.
6080 Deprecated REMOVE_ID packet type since it is not needed anymore
6083 Added silc_server_send_notify_server_signoff to send the
6084 SERVER_SIGNOFF notify type. Deprecates the function
6085 silc_server_send_remove_id.
6087 Added also silc_server_send_notify_signoff to send the
6088 SIGNOFF notify type.
6090 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6091 SILC protocol from this day on. Changed the protocol
6092 specification as well.
6094 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6095 notify type. It is used between routers to notify about
6096 topic changes on a channel.
6098 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6101 * Partly updated the protocol specification to comply with the
6102 changes now made. It is still though a bit outdated.
6104 * The JOIN notify type now takes one extra argument <Channel ID>.
6105 The packet used to be destined to the channel but now the
6106 JOIN type may be sent as list thus it is impossible to
6107 destine it to any specific channel. By adding this argument
6108 it is again possible.
6110 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Added CREDITS file. The CHANGES and CREDITS file will appear
6113 in the distribution as well.
6115 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6118 types in the server's silcd/packet_receive.c.
6120 * Implemented CMODE and CUMODE to work in router environment.
6122 * Fixed minor encoding and decoding buglet from the
6123 lib/silccore/silcmode.c.
6125 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6128 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6130 * Changed all SilcConfigServer* and silc_config_server* to
6131 SilcServerConfig* and silc_server_config*, respectively.
6134 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Associated the ID (client or server ID) to the Authentication
6137 Payload to avoid any possibility of forging. Updated the
6138 protocol specification and the code accordingly.
6140 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * The RSA key length is now save to the RsaKey context in the
6143 key generation process in lib/silccrypt/rsa.c. The key length
6144 is now used to figure out the maximum size of the block allowed
6145 to be encrypted/signed.
6147 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6148 is equivalent to the silc_mp_mp2bin but does not allocate any
6151 * Changed silc_mp_mp2bin API to take length argument. If it is
6152 non-zero then the buffer is allocated that large. If zero, then
6153 the size is approximated using silc_mp_sizeinbase, which however
6156 * Created Global RNG API which is global RNG that application can
6157 initialize. After initializing, any routine anywhere in the
6158 code (including library) can use RNG without allocating a new
6159 RNG object. This was done to allow this sort of use of the
6160 RNG in code that has no chance to allocate RNG object. All
6161 applications currently allocate this and many routines in the
6162 library use this. Affected file lib/silccrypt/silcrng.[ch].
6164 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6165 it to use the Global RNG API.
6167 * Defined Authentication Payload into protocol specification that
6168 is used during SILC session to authenticate entities. It is
6169 used for example by client to authenticate itself to the server
6170 to obtain server operator privileges.
6172 Implemented this payload into the lib/silccore/silcauth.[ch].
6173 Implemented also routines for public key based authentication
6174 as the new protocol specification dictates.
6176 Moved definitions of different authentication methods from
6177 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6179 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6180 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6181 silc_pkcs_verify_with_hash functions into the file
6182 lib/silccrypt/silcpkcs.[ch].
6184 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * The client entry's userinfo pointer must be always valid.
6187 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6188 will fail since it requires the userinfo. Now, the userinfo
6189 is allocated as "" if actual userinfo does not exist. Actually,
6190 it must exist and it is totally Ok to drop client connections
6191 that does not announce the userinfo. However, we will make
6192 this workaround for now.
6194 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6195 to return the remote port by socket.
6197 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6200 SILC_SERVER_PENDING_EXEC and added an new macro
6201 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6202 data or when error occurs while processing the pending command.
6204 Added new argument `destructor' into silc_server_command_pending
6205 and to the SilcServerCommandPending object. This destructor is
6206 now called after calling the pending callback or if error occurs
6207 immediately. If error occurs the actual pending callback won't
6208 be called at all - only the destructor. The destructor may be
6209 NULL if destructor is not needed.
6211 All this applies for client library code as well. Similar
6212 changes were made there as well for the pending commands.
6214 In the client, the application must now allocate the
6215 SilcClientCommandContext with the silc_client_command_alloc
6218 * Added reference counter to the SilcServerCommandContext. Added
6219 function silc_server_command_alloc and silc_server_command_dup
6222 Same type of functions added to the client library for the same
6225 * Removed the cmd_ident from IDListData away since it is now
6226 global for all connections. It is the command identifier used
6227 in command sending and with pending commands. The affected file
6230 * Added reference counter to the SilcSocketConnection objecet to
6231 indicate the usage count of the object. The object won't be
6232 freed untill the reference counter hits zero. Currently only
6233 server uses this, and client ignores it. The client must be
6234 set to use this too later. The affected files are
6235 lib/silccore/silcsockconn.[ch]. Added also the function
6236 silc_socket_dup to increase the reference counter.
6238 This was mainly added because it is possible that the socket
6239 is removed underneath of pending command or other async
6240 operation. Now it won't be free'd and proper DISCONNECTING
6241 flags, etc. can be set to avoid sending data to connection that
6242 is not valid anymore.
6244 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6245 the connection. After that it sets SILC_SET_DISCONNECTED.
6246 It is, however, possible that the socket data is not still freed.
6247 The silc_server_packet_process now checks that data is not
6248 read or written to connection that is DISCONNECTED. The socket
6249 get's freed when the reference counter hits zero.
6251 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Changed the client operation API: channel_message operation's
6254 `sender' is now the client entry of the sender, not the nickname
6255 and the `channel' is the channel entry, not the channel name.
6257 In the private_message operation the `sender' is now also the
6258 client entry of the sender not the nickname.
6260 Affected file is lib/silcclient/ops.h and all applications
6261 using the client operations.
6263 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Moved the calling of ops->connect() from connect_to_server_final
6266 into receive_new_id functin since that is the point when the
6267 client is actually allowed to send traffic to network. The
6268 affected file is lib/silcclient/client.c.
6270 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6273 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6274 (if needs broadcasting) instead of broadcasting the packets one
6275 by one which would make a burst in the network traffic.
6277 * Added `broadcast' argument to the functions in silcd/server.[ch]
6278 silc_server_create_new_channel[_with_id] to indicate whether
6279 to send New Channel packet to primary router.
6281 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Added new function into the silcd/server.[ch] files:
6284 silc_server_create_new_channel_with_id to create new channel with
6285 already existing Channel ID.
6287 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6288 lib/silccore/silcpacket.h. This packet is used t send list of
6289 Set Mode payloads inside one packet. Server uses this to set
6290 the modes for the channels and clients on those channels, that it
6291 announced to the router when it connected to it. The protocol
6292 specification has been updated accordingly.
6294 * The silc_server_new_channel did not handle the packet coming
6295 from normal server as it normally does not send that. However,
6296 when it announces its channels it does send it. Implemented
6297 the support for that.
6299 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6300 into the file lib/silccore/id.h.
6302 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Fixed memory leaks in the functions silc_idlist_del_client,
6305 silc_idlist_del_channel and silc_idlist_del_server in the file
6306 silcd/idlist.c. All of those leaked like a sieve.
6308 * Fixed some small memory leaks in the client's function
6309 silc_client_notify_by_server.
6311 * Added functions into silcd/server.c: silc_server_announce_clients,
6312 silc_server_announce_channels and silc_server_announce_server.
6313 These functions are used by normal and router server to announce
6314 to its primary router about clients, channels and servers (when
6315 router) that we own. This is done after we've connected to the
6318 These functions effectively implements the following packet types:
6319 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6320 and SILC_PACKET_NEW_ID_LIST.
6322 * Added new functions into the silcd/packet_receive.[ch]:
6323 silc_server_new_id_list, silc_server_new_channel_list and
6324 silc_server_new_channel_user_list to handle the incoming
6325 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6327 * Added support of changing Channel ID in the function
6328 silc_server_replace_id. If the server that announces a channel
6329 to the router already exists in the router (with same name but
6330 with different Channel ID), router is responsible to send
6331 Replace ID packet to the server and force the server to change
6332 the Channel ID to the one router has.
6334 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6335 client that the Channel ID has been changed by the router. The
6336 normal server sends this to the client. Client must start using
6337 the new Channel ID as the channel's ID.
6339 Implemented handling of this new type into lib/silcclient/client.c
6340 into the function silc_client_notify_by_server.
6342 * Added new function silc_idlist_replace_channel_id into the files
6343 silcd/idlist.[ch] to replace the Channel ID.
6345 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Call silc_server_command_identify_check always when processing
6348 the IDENTIFY command in silcd/command.c
6350 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6353 send keepalive packets. The packet can be sent by clients,
6354 servers and routers.
6356 Added function silc_socket_set_heartbeat into the file
6357 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6358 If not set, the heartbeat is not performed. The actual
6359 heartbeat is implemented in the low level socket connection
6360 library. However, application is responsible of actually
6363 Added silc_server_send_heartbeat to send the actual heartbeat
6364 packet into silcd/packet_send.[ch]. Server now performs
6365 keepalive with all connections.
6367 * Added silc_task_get_first function into lib/silcutil/silctask.c
6368 to return the timeout task with shortest timeout. There was a bug
6369 in task unregistration that caused problems. TODO has been
6370 updated to include that task system must be rewritten.
6372 * The client library will now resolve the client information when
6373 receiving JOIN notify from server for client that we know but
6374 have incomplete information.
6376 * Rewrote parts of silc_server_remove_from_channels and
6377 silc_server_remove_from_one_channel as they did not remove the
6378 channel in some circumstances even though they should've.
6380 * Encryption problem encountered in server:
6382 The LEAVE command used to send the Channel Key packet to the
6383 router immediately after generating it. However, the code
6384 had earlier sent Remove Channel user packet but not immediately,
6385 ie. it was put to queue. The order of packets in the router
6386 was that Channel Key packet was first and Remove Channel User
6387 packet was second, even though they were encrypted in the
6388 reverse order. For this reason, MAC check failed. Now, this
6389 is fixed by not sending the Channel Key packet immediately but
6390 putting it to queue. However, this is more fundamental problem:
6391 packets that are in queue should actually not be encrypted
6392 because packets that are sent immediately gets encrypted
6393 actually with wrong IV (and thus MAC check fails). So, packets
6394 that are in queue should be encrypted when they are sent to
6395 the wire and not when they put to the queue.
6397 However, the problem is that the current system has not been
6398 designed to work that way. Instead, the packet is encrypted
6399 as soon as possible and left to the queue. The queue is then
6400 just purged into wire. There won't be any fixes for this
6401 any time soon. So, the current semantic for packet sending
6404 o If you send packet to remote host and do not force the send
6405 (the packet will be in queue) then all subsequent packets to the
6406 same remote host must also be put to the queue. Only after the
6407 queue has been purged is it safe again to force the packet
6410 o If you send all packets immediately then it safe to send
6411 any of subsequent packets through the queue, however, after
6412 the first packet is put to queue then any subsequent packets
6413 must also be put to the queue.
6415 Follow these rules and everything works fine.
6417 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Added new function silc_server_remove_clients_by_server to
6420 remove all client entries from ID list when the server connection
6421 is lost. In this case it is also important to invalidate all
6422 client entires as they hold the invalid server entry. This
6423 fixes fatal bug when server has lost connection and will reconnect
6426 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Made some sanity checks to silc_server_daemonise like to check
6429 whether the requested user and group actually exists.
6431 * Added sanity check to SKE's silc_ske_responder_finish to check
6432 that the public and private key actually is valid.
6434 * Invalidate the client's nickname when receiving Replace ID
6435 packet and the Client ID is being replaced. This means that the
6436 server will query the nickname if someone needs it (client)
6439 * Sort the ID Cache in client library when the ID Cache data
6440 has changed (needs sorting).
6442 * Do not allow for SILC client to create several connections to
6443 several servers. The client does not support windows right now
6444 and generating multiple connections causes weird behaviour.
6446 Irssi-silc client does support windows and can handle several
6447 connections without problems, see: www.irssi.org and SILC plugin.
6449 * Fixed some places where client was added to the IDList. The
6450 rule of thumb is following (in order to get everything right):
6451 If the client is directly connected local client then the
6452 `connection' argument must be set and `router' argument must be
6453 NULL to silc_idlist_add_client function. If the client is not
6454 directly connected client then the `router' argument must
6455 bet set and the `connection' argument must be NULL to the
6456 silc_idlist_add_client function.
6458 * The funtion silc_server_packet_send_local_channel actually did
6459 not check whether the client was locally connected or not. It
6460 does that now. Fixed a bug related to LEAVE command.
6462 * Fixed Remove Channel User payload parsing bug in server's
6463 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6465 * The server's silc_server_save_channel_key now checks also the
6466 global ID list for the channel as it might not be in the local
6467 list. Fixed a bug related to LEAVE command.
6469 * Is this the end of the [<unknown>] buglet that has been lurking
6470 around for a long time? A little for loop fix in server's
6471 silc_server_command_whois_parse that is used by both IDENTIFY
6472 and WHOIS command. At least, this was a clear bug and a cause
6473 of one type of [<unknown>] buglet.
6475 * WHOIS and IDENTIFY commands call the function
6476 silc_server_command_[whois/identify]_check function even if
6477 we are not router server.
6479 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Added --with-gmp configuration option. If set the GMP
6482 is always compiled in the SILC source tree. If not set then
6483 it is checked whether the system has the GMP3 installed. If
6484 it has then the GMP won't be compiled (the system's headers
6485 and library is used), if it doesn't have it then the GMP is
6486 compiled in the SILC source tree.
6488 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Changed RSA private exponent generation to what PKCS #1
6491 suggests. We try to find the smallest possible d by doing
6492 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6493 not security fix but optimization.
6495 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added new config entry [Identity] to fork the server and run
6498 it as specific user and group. A patch from Bostik.
6500 * Imported Dotconf configuration library into lib/dotconf.
6501 This will be used to create the SILC configuration files later.
6502 It will appear in the distsribution after this commit.
6504 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * A big code auditing weekend happening. Auditing code for
6507 obvious mistakes, bugs and errors. Also, removing any code
6510 Removed files for being obsolete:
6512 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6513 inline in the file lib/silcutil/silcbuffer.h)
6515 o lib/silcutil/silcbufutil.c (the header has inline versions)
6517 Changed code to fix possible error conditions:
6519 o The buffer formatting routines now check that the destination
6520 buffer really has enough space to add the data. This applies for
6521 both buffer formatting and unformatting
6522 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6523 unformatting was changed to accomodate following rules:
6524 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6525 sent to the function while XXX_*STRING will not allocate or copy
6526 the data into the buffer. Instead it sets the pointer from the
6527 buffer into the pointer sent as argument (XXX_*STRING used to
6528 require that the pointer must be allocated already). This change
6529 makes this whole thing a bit more consistent and more optimized
6530 (note that the data returned in the unformatting with XXX_*STRING
6531 must not be freed now). The routines return now -1 on error.
6533 o Tried to find all code that use buffer_format and buffer_unformat
6534 and added return value checking to prevent formatting and
6535 especially unformatting errors and possible subsequent fatal
6538 o Changed ske->x and ske->KEY to mallocated pointers in
6539 lib/silcske/silcske.h. Fixed possible data and memory leak.
6541 o Added return value checking to all *_parse* functions. Fixed
6542 many memory leaks as well.
6544 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6545 so that buffer overflows would not happen. All code now also
6546 checks the return value as it can fail.
6548 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Added reconnection support to server if the normal server looses
6551 its connection to the router (for example if router is rebooted).
6552 The server performs normal reconnection strategy implemented
6553 to the server. Affected file silcd/server.c.
6555 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Added new packet type SILC_PACKET_SET_MODE that is used to
6558 distribute the information about changed modes (for clients,
6559 channels and clients channel modes) to all routers in the
6560 network. Updated the protocol specification accordingly.
6562 Added functions into silcd/packet_send.c and
6563 silcd/packet_receive.c: silc_server_send_set_mode,
6564 silc_server_set_mode.
6566 Added new files silcmode.[ch] into lib/silccore that implements
6567 the encoding and decoding of Set Mode Payload. Added new type
6568 SilcSetModePayload. Moved the definitions of different modes
6569 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6571 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Oops, a little mistake in server's connection authentication
6574 protocol. The protocol is not ended with FAILURE but with
6575 SUCCESS if the authentication is Ok. :) Affected file is
6578 * Implemented NICK_CHANGE notify handling in server in the file
6579 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6580 the local clients on the channel. After the changing nickname
6581 in router environment snhould work and the [<unknown>] nickname
6582 should appear no more.
6584 The silc_server_replace_id function that receives the Replace ID
6585 payload now sends the NICK_CHANGE notify type also in the file
6586 silcd/packet_receive.c
6588 * Changed WHOIS and IDENTIFY command to support the maximum amount
6589 of arguments defined in protocol specs (3328 arguments). This
6590 fixed a bug that caused problems when there were more than three
6593 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Added extra parameter, command identifier, to the
6596 silc_client_send_command so that explicit command identifier
6599 Changed that ID list routines uses specific command identifier
6600 when sending WHOIS/IDENTIFY requests to the server so that they
6601 can be identified when the reply comes back.
6603 Affected files lib/silcclient/command.[ch],
6604 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6606 * Added `sender' argument to silc_server_packet_send_to_channel
6607 to indicaet the sender who originally sent the packet to us
6608 that we are now re-sending. Ignored if NULL. Affected file
6609 silcd/packet_send.[ch].
6611 * Added some server statistics support in silcd/server_internal.h
6612 SilcServerStatistics structure and around the server code. Also
6613 send some nice statistics information when client is connecting
6616 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Fixed channel ID decoding in server's JOIN command reply in
6619 silcd/command_reply.c
6621 * Fixed braodcasting of replace ID payload to not to send it if
6622 we are standalone server in silcd/packet_receive.c.
6624 * Fixed all channel message sending routines to not to send
6625 packets to clients that has router set, since they are routed
6626 separately in the same function earlier. Affects file
6627 silcd/packet_send.c and all channel packet sending functions.
6629 * In USERS reply, res_argv[i] are not allocated, the table
6630 is allocated. Thus changed that free the table, not its
6633 * In server's whois_check and identify_check if the client is
6634 locally connected do not send any WHOIS commands - they are not
6637 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Fixed some minor bugs in client when sending WHOIS command. The
6640 arguments was in wrong order.
6642 * Removed statis function add_to_channel from server in
6643 silcd/command.c that was previously used with the joining but
6646 * Tested USERS command in router environment successfully with two
6647 routers, two servers and two clients.
6649 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Reorganized the USERS command and command reply in client library
6652 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6653 When the command is given by user we register a pending command
6654 callback that will reprocess the command after the reply has been
6655 received from the server. When reprocessing the packet we then
6656 display the information. Thus, the USERS information is displayed
6657 now in the command callback instead of in the command reply
6658 callback. The processing of the command is same as previously
6659 when server has sent the command reply in the JOINing process.
6661 * Added to USERS command in silcd/command_reply.c to join the client,
6662 we didn't use to know about, to the channel after we've created
6663 a client entry for it. Also, for clienet we did know already still
6664 check whether it is on the channel or not and add it if not.
6666 * Removed silc_server_command_join_notify as the function and its
6669 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Changed the client's pending command handling to the same as the
6672 server's pending command handling. It is also now possible to
6673 execute command reply functions from other command reply
6674 function as the function callbacks for commands and command
6675 replies are one and same. The pending commands are not static
6676 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6677 in client connection context. Thus, pending commands are server
6678 connection specific as it is convenient.
6680 Changed the function silc_client_command_pending and
6681 silc_client_command_pending_del and added new function
6682 silc_client_command_pending_check. Removed the
6683 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6686 * Added cmd_ident, current command identifier, to the client
6687 connection context in lib/silcclient/client.h to keep track on
6688 command identifiers used in command sending. Client's command reply
6689 function handling now supports the mandatory command identifiers.
6691 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6692 funtions in client to fully support pending command callbacks.
6694 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6695 as one of the arguments to the application in the command reply
6698 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6699 before first releasing SILC but came back. Now it is removed again
6700 and should come back nomore. The FORWARDED flag was used only
6701 by the JOINing procedure by forwarding the command packet to router.
6702 Now, the JOINing procedure has been changed to more generic (due
6703 to various router environment issues) and FORWARDED is not needed
6704 anymore for anything. The protocol specification is yet to be
6707 Now, removed silc_server_packet_forward from server and the flag
6708 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6710 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Renamed NAMES command to USERS command. The NAMES was named that
6713 due to historical reasons. Now it is renamed. Also, rewrote
6714 parts of the USERS command. The nickname list is not sent anymore
6715 by the server. Only Client ID and mode lists are sent in the USERS
6716 command. Changed this also to the protocol specification.
6718 The client now resolves the names and stuff after it receives
6719 the USERS list from the server when joining to the channel.
6721 * WHOIS and IDENTIFY commands has been changed to support multiple
6722 Client ID's per command. One can now search for multiple users
6723 in the network by sending only one WHOIS or IDENTIFY command.
6724 Changed the code and the protocol specifications.
6726 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6727 uses silc_server_command_whois_parse to parse the request. */
6729 * If normal server, do not parse the WHOIS and IDENTIFY requests
6730 before sending it to the router. Saves some time.
6732 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Fixed JOIN command on client library. Wrong number of arguments
6735 used to crash the client.
6737 * Added silc_server_channel_has_global function to check whether
6738 channel has global users or not.
6740 * Added silc_server_channel_has_local function to check whether channel
6741 has locally connected clients on the channel.
6743 * The silc_server_remove_from_one_channel now checks whether the
6744 channel has global users or not after given client was removed from
6745 the channel. It also checks whether the channel has local clients
6746 on the channel anymore. If it does not have then the channel entry
6747 is removed as it is not needed anymore.
6749 * The silc_server_notify now checks on JOIN notify whether the joining
6750 client is one of locally connected or global. If it is global then
6751 the channel has now global users on the channel and that is marked
6752 to the channel entry. Also, it now saves the global client to
6753 global list who is joining and JOINs it to the channel. This is
6754 for normal server, that is.
6756 Changed silc_server_send_notify_on_channel,
6757 silc_server_packet_relay_to_channel and
6758 silc_server_packet_send_to_channel check if we are normal server
6759 and client has router set (ie. global client) do not send the
6760 message to that client, as it is already routed to our router.
6762 * Implemented LEAVE notify type handling in silc_server_notify
6765 * Tested LEAVE command in router environment successfully. Tested
6766 with two routers, two servers and two clients.
6770 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6772 * Implemented SIGNOFF notify type handling in silc_server_notify
6775 * silc_server_remove_id now removes the client entry from all channels
6776 it has joined and thusly sends SIGNOFF notify type.
6778 * Rewrote the NAMES list generation in server by removing two excess
6779 loops. The lists are created now inside one loop.
6781 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * silc_server_remove_channel_user checks now also global list
6784 for channel and client.
6786 * silc_server_new_channel_user checks now both local and global
6787 list for channel and client. Fixed a bug in client id decoding.
6788 Used to decode wrong buffer.
6790 * silc_server_channel_message checks now both local and global
6791 list for channel entry.
6793 * Tested channel joining (hence JOIN) in router environment
6794 successfully. Tested with two routers, two servers and two
6797 * Tested channel message sending in router environment successfully.
6799 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Added silc_server_save_channel_key into server.[ch] to save the
6802 received channel key in Channel Key payload processing. It is
6803 also used in JOIN command reply handling.
6805 Equivalent function silc_client_save_channel_key added into
6806 client.[ch] into client library.
6808 * Changed JOIN command reply to send information whether the channel
6809 was created or not (is existing already) and the channel key
6810 payload. Changed protocol specs accordingly.
6812 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6813 the request was sent by ID and not by nickname. Crashed on
6816 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6819 now correctly save the received data.
6821 * silc_server_free_sock_user_data now notifies routers in the
6822 network about entities leaving the network.
6824 At the same time implemented functions silc_server_remove_id
6825 and silc_server_send_remove_id to receive and send REMOVE_ID
6826 packets. The packet is used to notify routers in the network
6827 about leaving entities. The ID removed will become invalid in
6830 * Added function silc_idlist_del_server into server. Removes and
6831 free's server entry from ID list.
6833 * silc_server_private_message function now checks, if we are router,
6834 that the destination ID really is valid ID, naturally.
6836 * In router when NEW_ID packet is received (for new client) the
6837 hash of the Client ID is saved in the ID Cache but the
6838 client->nickname is set to NULL, instead of putting the hash
6841 IDENTIFY command now also checks that client->nickname must be
6842 valid. If it is not if will request the data from the server who
6843 owns the client. Added new function
6844 silc_server_command_identify_check.
6846 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6847 to set the command to already allocated Command Payload.
6849 * Tested private message sending in router environment with two
6850 routers, two servers and two clients. Fixed minor bugs and now
6853 * Fixed segfault from client's NAMES command. Used to crash if
6856 * Forwarded packets must not be routed even if it is not destined
6857 to the receiver. Changed server code comply with this.
6859 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Added `require_reverse_mapping' boolean value to ServerParams
6862 structure. If TRUE (not default) the server will require that
6863 the connecting host has fully qualified domain name.
6865 If the reverse mapping is not required and hostname could not be
6866 found the IP address is used as hostname.
6868 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Implemented version string checking to both client and server.
6871 The check is incomplete currently due to the abnormal version
6872 strings used in development version of SILC.
6874 * Changed all command functions in server to use the new
6877 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Changed char *data to unsigned char *data in ID Cache system to
6880 support binary data as ID Cache data. Changed code to support
6881 binary data in lib/silccore/idcache.c.
6883 * Renamed silc_server_packet_relay_command_reply to
6884 silc_server_command_reply as it is normal packet receiving
6885 function. Rewrote the function to accept command replys for
6886 servers and not only for clients.
6888 * Mark remote router always as registered server if we are connecting
6889 to it. Otherwise, commands sent by the router to us are ignored.
6891 * All ID List find routines now returns the ID Cache Entry pointer
6892 as well if requested.
6894 * WHOIS command works now in router environment, tested with two
6895 routers, two servers and two clients.
6897 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6898 in router environment (as it is almost equivalent to WHOIS) but
6899 hasn't been tested thoroughly. Added new functions:
6901 silc_server_command_identify_parse
6902 silc_server_command_identify_send_reply
6903 silc_server_command_identify_from_client
6904 silc_server_command_identify_from_server
6906 * Disabled route cache adding because adding two different ID's with
6907 same IP replaces the old cache entry thus giving wrong route.
6908 The entry->router->connection is always the fastest route anyway
6909 so route cache may not be needed. Of course, new routes maybe
6910 established after receiving the ID when the entry->router->connection
6911 might not be anymore the most optimal.
6913 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Add route cache for received ID for fast routing.
6917 * Added silc_server_packet_route to route received packet on router
6918 that is not destined to us.
6920 * Renamed silc_server_get_route to silc_server_route_get.
6922 * Added id_string and id_string_len fields into SilcServer to
6923 include encoded ServerID for fast comparing without excess
6924 encoding of the ID's.
6926 * Cleaned up WHOIS command on server side. Added following static
6929 silc_server_command_whois_parse
6930 silc_server_command_whois_check
6931 silc_server_command_whois_send_reply
6932 silc_server_command_whois_from_client
6933 silc_server_command_whois_from_server
6935 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6936 arguments in command replies. All command functions should be
6937 updated to use this macro.
6939 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6941 * Minor typo fixes on command reply handling on server.
6943 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Added silc_server_command_add_to_channel internal routine to add
6946 the client to the channel after router has created the channel and
6947 sent command reply to the server.
6949 * Added generic silc_server_send_command to send any command from
6952 * Use static buffer with ID rendering instead of duplicating data.
6954 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6956 * Fixed a channel user mode bug when joining to a channel server gave
6957 everybody channel founder rights, oops.
6959 * We mark ourselves as the router of the incoming server connection
6960 if we are router ourselves. This way we can check in some packet
6961 sending functions whether it is locally connected server. For
6962 incoming router connections we put NULL.
6964 * For router sending packets locally means now always sending the
6965 packet cell wide; to local clients and local servers. For normal
6966 server sending packet locally means sending it to only local
6969 * Fixed the JOIN command to really work in router environment. If the
6970 channel is created it is always created by the router. Router is
6971 also responsible of making the initial joining to the channel,
6972 sending JOIN notify to the sending server and distributing
6973 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6974 does not exist server doesn't do anything else but forward the
6975 command to the router which performs everything.
6977 * Added silc_server_send_channel_key function to send the Channel Key
6980 * Added silc_server_create_channel_key to create new channel key. The
6981 channel key is now re-generated everytime someone joins or leaves
6982 a channel, as protocol dictates. Note: channel->key_len is the
6985 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6988 packet_receive.[ch] to separate packet sending and receiving
6989 routines. The server.[ch] now includes everything else including
6990 actual packet processing (writing and reading data) and other
6993 Renamed silc_server_private_message_send_internal to
6994 silc_server_send_private_message. The routine is still though
6995 used only to relay private messages as server does not send
6996 private messages itself.
6998 Renamed silc_server_new_channel to silc_server_create_new_channel
6999 and added new function sicl_server_new_channel that handles the
7000 incoming New Channel packet. Added also new sending function
7001 silc_server_send_new_channel to send New Channel Payload.
7003 * Added new function silc_server_notify to process incoming notify
7004 packet to the server/router. Server may then relay the notify
7005 to clients if needed.
7007 * Added new function silc_server_new_channel_user to process incoming
7008 New Channel User packet. Router will redistribute the packet and
7009 send JOIN notify to its local clients and locally connected servers
7010 if needed. Normal server will send JOIN notify to its local client
7011 on same channel when received this packet. Added also corresponding
7012 sending function silc_server_send_new_channel_user to sent the
7015 * Added boolean route argument to send_notif_to_channel and
7016 packet_send_to_channel functions to attempt to route the packet
7017 if it is TRUE and send only locally if it is FALSE.
7019 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7021 * silc_server_replace_id now broadcasts the received replace ID
7022 packet if it is not broadcast packet already. The router must
7023 broadcast to inform other routers about changed ID.
7025 * Added backpointer to server's router into SilcServer context in
7026 silcd/server_internal.h.
7028 * Fixed silc_server_packet_broadcast to send correct broadcast
7031 * The channel key is now distributed to the local client as soon
7032 as it is received from the router (in router environment) so that
7033 no other packet may be sent for the channel until client has
7036 * silc_server_remove_channel_user now broadcasts the received
7037 Remove Channel User packet if it is not broadcast packet already.
7038 The router must broadcast to inform other routers about removed
7041 * Added users field into SilcPacketContext that is a reference count
7042 of the context. One can increase the reference count by calling
7043 silc_packet_context_dup which is now changed to just increase the
7044 reference count instead of duplicating the data. The reference
7045 count is decresed by calling silc_packet_context_free that will
7046 free the data after the reference count hits zero.
7048 For now on the packet context and everything allocated into it
7049 (including the raw packet from network) must be freed by calling
7050 the new silc_packet_context_free function. Added also new function
7051 silc_packet_context_alloc that must be used now to allocate the
7052 context. This also means that if a routine is asynchronous from
7053 silc_[client/server]_packet_parse_type the packet context must
7054 be duplicated by calling silc_packet_context_dup. Otherwise it
7055 gets free'd after silc_[client/server]_packet_parse_type returns.
7056 Also, one must remember that if packet is duplicated then its
7057 reference count must be decresed by calling the free function as
7058 many times as it was duplicated.
7060 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7061 from both client and server.
7063 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Made joining to a channel working in router environment.
7067 * Cleaned up JOIN command on server side and create function
7068 silc_server_command_join_channel internal routine to make the
7071 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Changed silc_command_pending list to SilcDList. Also, added
7074 `ident' field to SilcServerCommandPending structure to identify
7075 the reply and to call correct callback.
7077 Added silc_server_command_pending_check function to replace the
7078 corresnponding macro. The silc_command_pending list is not
7081 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7082 to set identifier to previously allocated Command Payload. It
7083 is used to set identifier for command when resending Command
7086 * Added silc_command_payload_encode_payload to encode Command
7087 Payload buffer from SilcCommandPayload structure.
7089 * Added silc_argument_payload_encode_payload to encode Argument
7090 payload buffer from SilcArgumentPayload structure.
7092 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7094 * Changed WHOIS command to support router connection on server side.
7095 The whois request is always sent to router unless the server is
7096 standalone server. After server has received the reply from the
7097 router will it send the reply to the client.
7099 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7100 broadcast received broadcast packet. The function is used only
7101 by router. The broadcast packet is always sent to the router's
7104 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7105 render given ID to printable string, for log files for example.
7107 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Made basic router to router connections working. At least they
7110 can now connect to each other but nothing really works the way
7111 they are supposed - yet.
7113 * Added new initiator token to RouterConnection configuration
7114 file in silcd/serverconfig.[ch]. It is used to tell whether we
7115 are the initiator to the remote router or whether we'll expect
7116 the other end to connect.
7118 * Moved registering of listener task to silc_server_init, hence
7119 the server starts listenning as soon as it is run, even if it
7120 does not have connections to other routers. Let's see how well
7123 * Changed default connection retry timeouts for more suitable in
7126 * Removed cipher and such arguments from silc_idlist_add_client
7127 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7128 Added new function silc_idlist_add_data to add the keys and stuff
7131 * Added SilcIDListData structure and added it to SilcClientEntry
7132 and SilcServerEntry as their first field in the structure. This
7133 way we can explicitly cast the ID entries to the SilcIDListData
7134 structure and get common data for the entries. In past, we had
7135 to first check what type of connection it is and then cast it to
7136 correct ID entry type. Now, we can directly cast the opaque
7137 pointer to the SilcIDListData (no matter what ID entry it actually
7138 is) and get the data needed.
7140 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7143 in some circumstances even if threre were timeout tasks, though not
7144 IO tasks, but tasks anyway. Now fixed.
7146 * Defined SilcServerConnection structure to hold connection specific
7147 stuff about directly connected servers and routers. The definition
7148 is currently in silcd/server_internal.h. I thought about having
7149 a bit more important role fro this struct but for now it is used
7150 only when connecting to other server (or router actually).
7152 * Added connecting retry support in server when connecting to
7153 router(s). The retry feature implement exponential backoff
7154 algorithm. Also, added SilcServerParams structure to hold default
7155 parameters for server. For now, it include these retry settings
7156 and are hard coded. After server is moded to be as Silc Server
7157 Library this structure will be more important.
7159 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Changed client librarys channel->clients table to SilcList and
7162 changed code accordingly.
7164 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Changed client's channel table to SilcList and changed code
7167 accordingly. Also changed SilcChannelClientEntry to include back-
7168 pointer to the channel so that client entry can use that structure
7169 as list as well and we have fast cross-reference to the channel.
7170 This change dramatically decreased the complexity of channel
7171 handling with client entry and vice versa (removed one extra
7172 loop when searching for channel entry from many functions).
7174 * Changed server->sim from table to SilcDList and changed code
7177 * NAMES command can now be used from user interface. It will show
7178 the user list on the channel, neatly.
7180 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7181 Code now saves realname of the user if it becomes available.
7183 * Renamed configure.in to configure.in.pre and made ./prepare
7184 script to automatically add correct version string to
7185 configure.in which it creates from configure.in.pre.
7187 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * NAMES command reply now shows users mode with the nickname when
7192 * Moved silc_client_ch[u]mode[_char] functions from
7193 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7194 place sucks, they are utility functions and should be in some
7197 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7199 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7202 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Added TRQ (efficient deque and list library) into lib/trq. This is
7207 a very good list library that is currently used in the SILC. Defined
7208 SilcList API over the library because I didn't like the API very
7209 much. See lib/trq/silclist.h for the API and examples of how to
7210 use the API. Fixed various places in the code to use the new
7211 SilcList API. The SilcList is meant for lists that has a structure
7212 already defined as a list. It is not suitable to add just some
7213 context to the list (in TRQ, the context is the list actually).
7215 So, I defined SilcDList that can be used for the purpose where
7216 predefined list structure does not exit. This can be used as
7217 such list. Now some context just can be added to the SilcDList.
7218 Currently this list is not used in the SILC just yet, though there
7219 are a lot places where this can replace dynamically allocated
7220 tables and I will fix these places, later, to use SilcDList.
7221 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7222 and use TRQ internally).
7224 Also fixed some annoying warning messages that the original TRQ
7225 code generated. Also minor changes to TRQ's Makefile.in.
7227 * Added support for querying by Client ID to both WHOIS and
7228 IDENTIFY commands into server, as required by the protocol.
7230 * Removed method function pointers from SilcBuffer structure. They
7231 weren't used to anything and just increased the context size for
7232 no good reason. This change also made silc_buffer_alloc and
7233 silc_buffer_free functions inline functions.
7235 * Disabled command flooding detection support until it's fixed so
7236 that it accepts commands in but does not execute them more than once
7239 * Added silc_net_localhost(), to return local hostname, into
7240 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7241 that must be initialized before calling silc_client_init.
7243 * Added new function: silc_server_send_notify_on_channels to send
7244 notify messages to all channels client has joined. It is assured
7245 that the message is sent only once per client.
7247 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7248 lib/silcutil/silcutil.[ch] as silc_format function. The new
7249 function is generic and is used by server as well, not only by
7250 the logging routines.
7252 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7253 the provided version string was not acceptable. Added new function:
7254 silc_ske_check_version into lib/silcske/silcske.h. The function
7255 must be implemented by the application (client or server) and it
7256 does not reside in the SKE library. The function checks the version
7257 string remote end sent.
7259 * Added back pointers (to opaque context and to SilcSocketConnection)
7260 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7262 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7263 duplicate packet context structure.
7265 * Changed `notify' client operation to send same arguments as client
7266 receives from server except for ID's. ID's are mapped to correct
7267 ID entry and that is returned. Also, if channel entry is not sent
7268 by server but the notify is for channel the channel entry is sent
7269 to application (otherwise application doesn't know that it is for
7270 channel (library gets it from packet's Destination ID)).
7272 * Added silc_client_remove_from_channels into client library to
7273 remove a client from all channels it has joined to. Used when
7274 received SIGNOFF notify from server. Added also new function
7275 silc_client_replace_from_channels to replace old ID entry with
7276 new ID entry on all channels. Used when received NICK_CHANGE
7279 * Fixed ID Cache list handling in silc_idlist_get_client in
7280 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7281 to get (or query) client by ID.
7283 * Updated TODO list.
7285 * Added connection authentication status message defined by the
7286 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7287 support for these into the code in client and server side.
7289 * Added generic function silc_client_send_command to send any command
7290 with variable argument list. Application should use this function
7291 to send commands if the command functions provided by the library
7292 does not suite for the application's user interface needs.
7294 * Added new `failure' client operation. Application is notified about
7295 received failure packet if client is executing a protocol. In this
7296 case the protocol's execution has failed.
7298 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7299 is required by the protocol.
7301 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7302 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7305 * Added status flag to SilcSKE object to indicate realtime status
7306 of the SKE protocol.
7308 * Application receives now exactly same command reply arguments as
7309 the library receives from server. However, if ID is received the
7310 corresponding ID entry is returned to the application (eg. Client
7311 ID is mapped to correct SilcClientEntry entry and that is returned).
7312 Changed command_reply client operation due to this change.
7314 * Changed all ID's in commands and in command replys as ID Payloads.
7315 Change affected both client and server side codes.
7317 All ID's sent in SILC network (with execption of ID's in SILC
7318 Packet header) are sent in ID Payload to support variable length
7321 * Server now notifies nick changes and notifies all clients on
7322 the channels about the new nickname (about the new Client ID,
7325 * Implemented CMODE command to change channel modes. Supports all
7326 channel modes defined by the protocol specs except ban and invite
7327 lists. (Also, private channel key mode is supported but support for
7328 setting private channel key in client is missing, thus, this mode
7329 has no effect on client side (except that server requires that the
7330 client uses private channel key and normal channel traffic does not
7333 Also, invite mode works per se, but INVITE command does not work
7334 yet correctly, so you can set channel as invite only channel but
7335 inviting clients to the channel does not work (it is yet to be
7336 thought what's the best way to do it).
7338 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7339 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7340 Implemented CUMODE command to change user's mode on the channel.
7341 Supports all modes defined by the protocol specs.
7343 * Added NAMES command reply to return users modes on the channel.
7345 * Removed unnecessary and slow ciphers from lib/silccrypt.
7347 * Set SO_KEEPALIVE option to connection sockets by default.
7349 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7351 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7352 redefined the Notify Payload into protocol specs.
7354 * Added silc_id_payload_parse_id to get ID directly from raw
7357 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7359 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7360 accept searching by Client ID as well.
7362 * Added support for LEAVE and SIGNOFF notify types in client library.
7364 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7365 to parse ID Payload from raw data.
7367 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7369 * Added flags parameter into silc_ske_assemble_security_properties
7370 function in lib/silcske/silcske.[ch].
7372 * Changed notify client operation to fit better for notify messages
7373 sent by server. The notify payload received from server is now
7374 passed to the application (after parsing it to SilcNotifyPayload).
7375 It is application's responsibility to retrieve the arguments
7376 from the payload and show the message the way it wants. The message
7377 sent by server is implementation specific.
7379 * Changed public keys to comply with the protocol specification.
7380 Old public keys are not supported anymore and are not compatible.
7382 * Removed nickname from Channel Payload as the latest draft removed
7383 it. The client must resolve the nickname from the NAMES command
7384 reply received when it joined the channel.
7386 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7388 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * Fixed some errors in protocol specification drafts.
7392 * Created lib/silccore/silcnotify.c to implement Notify Payload
7393 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7394 generic payloads described by protocol specifications. The file
7395 includes implementations for ID Payload and Argument Payload.
7397 * Changed Command Payload implementation to use the new Argument
7398 Payload. Changed command_xxxx_payload to command_payload_xxxx
7399 to comply with SILC coding conventions.
7401 * Added suppport for Argument Payload handling in Notify Payload
7402 implementation as protocol requires it. Added the new support
7403 into server and client lib as well.
7405 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * Added support for multiple nicknames on same channel. [n] is
7408 added locally to the nickname if there are more than one same
7409 nicknames on the channel.
7411 * Server now sends all nicknames that matched WHOIS request.
7412 Client also shows the list received from server.
7414 * Added TOPIC command to client side. User can now set and show
7415 current topic on channel.
7417 * Added MOTD command to client and server. Also, server sends the
7418 motd when client connects to the server.
7420 * Changed version strings to comply ISO 8601.
7422 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7424 * Fixed protocol error handling in client library. It should now
7425 cope even if the SKE fails for some reason.
7427 * Made new protocol specification drafts for submitting to IETF.
7429 * Implemented TOPIC command to server in silcd/command.c.
7431 * Added two new notify types into lib/silccore/silcnotify.h:
7432 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7433 notify nickname change and topic setting/change on a channel.
7435 * API change of command_reply operation in client library. The
7436 application gets now the status type received from server as well.
7438 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7440 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7442 * Cras fixed and optimized the packet handling even further and
7443 it should work now. Minor change to the prototype of function
7444 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7446 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Added new function into lib/silcutil/silcschedule.[ch]:
7449 silc_schedule_with_fd to select() a specified fd. The function
7450 returns after timeout expires or data arrives or goes. The
7451 function is used by packet routines to wait that all data is
7452 received from network.
7454 * Fixed data reading from network in lib/silccore/silcpacket.c.
7455 The code now assures that all data is read from the fd and then
7456 continues packet processing. This was a bug fix since the code
7457 used to drop some data in some circumstances.
7459 * Added new function into lib/silcclient/client.[ch]:
7460 silc_client_start_key_exchange to start key exchange after
7461 connection has been established to server. The code internally
7462 now uses this funtion but its main purpose was to provide it
7463 for applications that perform their own connecting. After
7464 application has created a connection it merely calls this
7465 function to start the key exchange between client and server.
7466 The library takes care of everything else after that.
7468 Updated also lib/silcclient/README to explain the usage of
7471 * Do not send to application information that connection has
7472 been established. Application gets notified it by connect
7475 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Applied cras's patch to add silc_schedule_one function. The
7478 function runs scheduler once and returns.
7480 * Fixed the scheduler after cras messed it up. The timeout
7481 handling works now as it's supposed to work.
7483 * Added into lib/silccore/ silcnotify.h to include notify
7484 message types support. Changed silc_server_send_notify*
7485 functions, in server.[ch], to support those new notify types.
7486 Added the support for the notify types into client library,
7487 as well. Added new notify client operation into ops.h in
7490 * Changed silc_server_packet_send_to_channel to send normal
7491 packets instead of just channel message packets. The function
7492 is now used to send the notify packets to channels. It is not
7493 used to send channel message packets anymore, as server never
7496 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7497 va_arg()s as it seems to require it nowadays. I guess, if SILC
7498 is compiled with older va_arg() the new code should work anyway.
7500 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7502 * Splitted core library. Core library (lib/silccore) includes
7503 now only SILC protocol specific core (and common) components.
7504 Created new utility library (lib/silcutil) that includes more
7505 generic purpose stuff. The stuff for util library was taken
7506 from the old core library. This was minor and easy split.
7508 * Created SILC Client Library (lib/silcclient) that includes
7509 implementation of the SILC client without user interface. This
7510 was major move from silc/ directory. The code has been changed
7511 so that it is transparent towards the user interface. The
7512 silc/ directory includes now the same user interface as before
7513 and it uses the new client library. Read lib/silcclient/README.
7514 Basicly, the client library performs everything else related
7515 to SILC except user interface handling. Also, configuration
7516 files are considered to be part of user interface and library
7517 does not handle them.
7519 This change also changed a lot of structures, function naming etc.
7520 Most important change was that SilcClientWindow object was
7521 renamed to SilcClientConnection in the client library. Created
7522 also new file lib/silcclient/ops.h. Also added new files
7523 silc/local_command.[ch] and silc/client_ops.[ch].
7525 All these changes were made to make it easier for user interface
7526 designers to create what ever user interface for the SILC client
7529 It is also expected that the server will be moved to lib
7530 directory as well and SILC Server Library will be created;
7531 sometimes in the future.
7533 * Removed Local commands from lib/silccore/silccommand.h as
7534 they are application specific and new client library does not
7535 handle any of those anymore.
7537 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7538 old client implementation in silc/.
7540 * Added support for callback functions in SILC_LOG_* macros.
7541 Application can now set its own callbacks that will be called
7542 instead of using the default functions that will always print
7543 the debug messages to stderr (or stdout). Also, debugging can
7544 now be disabled by setting silc_debug to FALSE and re-enabled by
7545 setting it to TRUE. Note, that logging will still work even
7546 if debugging is disabled.
7548 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7549 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7550 silc_log_reset_debug_callbacks.
7552 * To enable debugging in silc client one must give now -d
7553 option on command line.
7555 * Changed silc_schedule_init to automatically allocate task queues
7556 if they are not allocated before calling it.
7558 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Added GMP 3.1 into math library.
7562 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7564 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7565 a channel in SILC network. The packet is used by servers and
7566 routers to notify other routers that user has left a channel.
7567 This little feature was missing until now. Added the feature
7568 to protocol specification as well.
7570 Added functions: silc_server_send_remove_channel_user and
7571 silc_server_remove_channel_user into server.[ch].
7573 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7574 lib/silccore/silcpacket.h. However, they are not implemented
7577 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * Fixed joining to a channel and sending channel messages
7580 between server and router. The channel message sending should
7581 now work inside a cell.
7583 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7585 * Fixed the private message sending between server and router.
7586 The private message sending should now work inside a cell.
7588 * Added silc_server_replace_id into server.[ch] to replace
7589 existing ID in the SILC network.
7591 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7592 and silc_idlist_replace_server_id into idlist.[ch] in server.
7594 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7596 * Fixed the server to server connections. Server can again now
7597 connect to router. Router to router connections probably does
7600 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Added dynamic protocol registering support. Now protocols can
7603 registered and unregistered on the fly. Patch by cras.
7605 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7607 * Added lib/contrib directory to hold routines that some platforms
7608 don't have but are needed by SILC.
7610 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7611 into lin/contrib to provide getopt() and getopt_long() for
7612 those who don't have it.
7614 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7616 * Added AWAY command to client. When away message is set and
7617 client receives a private message packet the client automatically
7618 replies to the sender with the away message.
7620 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7621 bug seemed to be the cause of recent problems when compiling
7624 * Added version detection support to SKE protocol specification
7625 and added the new changes to the SKE implementation as well.
7626 There were other minor changes in the SKE protocol as well.
7628 Many changes in lib/silcske/silcske.[ch] and in
7629 lib/silcske/payload.[ch].
7631 * Added ^U functionality, clear input line. Patch from cras.
7633 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7635 * Mainly small bugfixes on core library. Fixed some debugging
7636 logging and buffer overflow in silclog.c.
7638 * Updated config.sub and config.guess on the distribution tree.
7640 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Added command lagging support in server. Client may execute
7643 commands now only once in two seconds.
7645 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Optimized packet reception. MAC computation and checking is now
7648 also more optimized. A lot previously duplicated code is now
7649 used as generic by both client and server.
7651 * Fixed key pair generation in clientutil.c
7653 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Added into lib/silccore/silcbufutil.[ch] new function;
7656 silc_buffer_realloc.
7658 * Moved generic packet sending/encryption functions to
7659 lib/silccore/silcpacket.[ch] from client and server. Some
7660 rewriting of the functions.
7662 * Moved all generic packet reception/decryption functions to
7663 lib/silccore/silcpacket.[ch] from client and server. The
7664 packet processing is now much cleaner in both client and server.
7665 These were major changes in both client and server.
7667 * Created many common functions in server to do packet sending.
7668 Previously code were duplicated a lot, this has been removed
7671 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Rewrote major parts of the ID cache system. Don't know
7674 whether it is better now or not but at least the API is more
7677 * Major rewrite on ID cache stuff on client because of the ID
7678 cache API changes. Added idlist.c to client.
7680 * Also major rewrite on ID cache stuff on server as well.
7681 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7682 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7683 in hand, instead they are all put into the ID cache system now.
7684 All server_idlist_* routines uses ID cache now instead of
7685 traversing its own lists (those lists does not exist anymore).
7686 SilcIDList though still exists. Also, SilcXXXEntry's are
7689 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Finally made the SKE implementation compliant to the protocol
7692 specification. All mp integers are now binary encoded as
7693 opposed being HEX encoded.
7695 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7698 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7699 functions: silc_[encode/decode]_pem. Also added function
7700 silc_encode_pem_file to PEM encode with newlines ('\n') for
7703 * SILC public keys are now encoded either PEM or binary. Same
7704 option is for private keys as well. By default private keys
7705 are binary encoded and public keys PEM encoded. Silly HEX
7706 encoding were removed.
7708 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7709 function to create fingerprints.
7711 * Fixed a bug in SHA1; does not change the original data anymore.
7713 * Partly implemented INFO command on client and server side.
7714 Fixed CLEAR command. Changes to SERVER command; show current
7715 server(s) when giving command without arguments. Added
7716 VERSION command to client.
7718 * Added check to server that unregistered connections cannot
7719 execute commands (unless it is specificly allowed).
7721 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7723 * Fixed screen refresh.
7725 * Fixed channel joining bug from client. On some circumstances
7726 client tried to join to a channel it had already joined.
7728 * Added public key verification process into client's protocol.c.
7729 The client now verifies the public key from user and saves
7730 it into ~./silc/serverkeys/ directory.
7732 Added into: clientutil.[ch]: silc_client_verify_server_key.
7734 * Changed SKE protocol's silc_ske_initiator_finish function
7735 to accept callback function that verifies the received public
7736 key. Removed old silc_ske_verify_public_key function.
7738 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7741 silc_pkcs_private_key[_data]_set.
7743 * Made the password and public authentication more cleaner in
7744 server's protocol.c.
7746 * Removed historic and obsolete protocol `channel_auth' from
7747 both client and server.
7749 * Removed wrong way of sending command status messages from
7750 server to client in server's command.c. The old way violated
7751 protocol specification.
7753 Changes to silccore/silccommand.[ch]: removed
7754 silc_command_encode_status_payload -> not needed anymore,
7755 changed silc_command_encode_payload_va to accept extra
7756 argument on variable argument list. The argument type must
7757 now be provided to the function. Also, added new function:
7758 silc_command_encode_reply_payload_va which is same as
7759 normal command_encode_payload_va except command status type
7760 is provided as extra argument.
7762 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Added ~./silc directory handling. The directory includes the
7765 public and private keys for the client.
7767 Added silc_client_check_silc_dir, silc_client_create_identifier
7768 and silc_client_load_keys.
7770 * Implemented SILC protocol compliant public key. Added public
7771 and private key saving to and loading from files.
7773 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7774 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7775 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7776 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7777 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7779 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7780 silc_pkcs_load_[public/private]_key.
7782 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Added silc_server_get_route (route.[ch]) to get connection
7785 data for the fastest route for given ID.
7787 * Implemented INVITE command on client and server. The command
7788 were re-defined in the SILC Protocol Specification and the
7789 implementation now complies with the specification.
7791 * Implemented PING command on client and server.
7793 * Implemented NAMES command on client and server. The server side
7794 supports currently only normal server not router server yet.
7795 Some changes to NAMES definition in SILC protocol specification.
7797 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7799 * Implemented LEAVE command on client and server.
7801 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7802 again. This change was made to the protocol as well. Server
7803 should not violate the protocol specification anymore.
7805 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7807 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7808 was tested. SOCKS4 was not but should work anyway.
