1 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed a bug in the silc_client_nickname_format function that
4 handles the multiple same nickname formatting. Two clients
5 with same nickname caused problems after the first one left
6 and rejoined. It didn't format the nickname correctly.
7 Affected file is lib/silcclient/idlist.c.
9 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
11 * Don't change the topic if olod topic is same as new one.
12 Affected file is silcd/packet_receive.c.
14 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
16 * Added cross-reference support to the SILC Documentation
17 generator. All types across all HTML files are now cross-
18 referenced. Affected files util/robodoc/generator.c and
19 scripts/silcdoc/silcdoc.
21 * Added file lib/silcutil/silctypes.h to include all the
22 arithmetic type definitions and some macros. Removed
23 includes/bitmove.h and moved macros to silctypes.h.
25 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
27 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
29 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Added `type' argument to silc_id_payload_parse_id function which
32 now returns the type of the ID to the sent pointer. Affected
33 file is lib/silccore/silcid.[ch].
35 * Added check for CMODE_CHANGE notify type that mode change is
36 allowed by the sender. Affected file silcd/packet_receive.c.
38 * Added check for CUMODE_CHANGE notify type that mode change is
39 allowed by the sender. Affected file silcd/packet_receive.c.
40 Added the ID type as CUMODE_CHANGE notify type as argument
41 to the `notify' client operation. Affected files are
42 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
44 * Added function silc_client_add_server to the client library.
45 Added support for resolving also channel and server info when
46 received unknown entity in notify packet. Affected files are
47 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
49 * Added function silc_command_get_status to return the command
50 status from the command reply's argument payload. Affected files
51 are lib/silccore/silccommand.[ch].
53 * Added check for KICKED notify type that the kicking is
54 allowed by the client. Affected file silcd/packet_receive.c.
56 * Created function silc_get_input which can be used to get input
57 (echo on or off) from user on command line. Affected files are
58 lib/silcutil/silcutil.[ch].
60 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
62 * Optimized silc_server_packet_relay_to_channel function.
63 Added new function silc_channel_message_payload_encrypt which
64 can be called directly if channel message payload needs to
65 be encrypted and is already encoded (no need to call _encode
66 function). Packet relaying is now done by router without any
67 extra memory allocations. Affected files are
68 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
71 * Fixed the INVITE notify handling. It took wrong arguments
72 as invite list and invite delete. Affected file is
73 silcd/packet_receive.c.
75 * Added check for TOPIC_SET notify type that the topic change is
76 allowed by the client. Affected file silcd/packet_receive.c.
78 * Added check for INVITE notify type that inviting is allowed by
79 the client. Affected file silcd/packet_receive.c.
81 * Changed the silc_server_client_on_channel to return the
82 SilcChannelClientEntry as well. Moved the function
83 silc_server_check_cmode_rights to server_util.[ch].
84 Affected files are silcd/server_util.[ch], silcd/command.c.
86 * Added function silc_server_check_umode_rights to check whether
87 changing client's user mode is allowed. Added check for
88 UMODE_CHANGE notify type that the umode change is allowed
89 by the client. Affected files are silcd/server_util.[ch],
90 silcd/packet_receive.c and silcd/command.c.
92 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
95 ID length. It ignored that ID can be IPv6 based as well.
96 Affected file lib/silccore/silcpacket.h.
98 * Fixed the silc_id_id2str and silc_id_str2id to take the
99 IPv6 address offset's into consideration. Affecte file is
100 lib/silccore/silcid.c.
102 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
104 * Fixed the internal Unix scheduler functions to check for
105 NULL context they may receive. The affected file is
106 lib/silcutil/unix/silcunixschedule.c.
108 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
110 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
111 can specify different directory with --home command line
112 parameter. Affected files irssi/src/silc/core/client_ops.c,
115 * SILC-specific commands aren't now executed if the active server
116 isn't of SILC-type, so there won't be problems with having
117 IRC and SILC protocol support in same client. Affected files
118 irssi/src/silc/core/silc-channels.c, silc-servers.c,
121 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
123 * Improved the signal support in SILC Schedule. Added new
124 function silc_schedule_signal_call which is used by application
125 to mark a signal to be called. It is now safe to perform
126 any kind of tasks in signal callbacks since it is guaranteed
127 that the application specified signal callback is called
128 after the signal is over. Affected files are
129 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
131 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
133 * Added `name' field to SilcChannelPrivateKey to represent
134 application given name for the key. Moved also the context from
135 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
136 Added the `name' argument also to the function
137 silc_client_add_channel_private_key.
139 Added function silc_client_current_channel_private_key to set the
140 current channel private key in use.
142 Added "change" command to KEY command which can be used to change
143 the current channel private key. Bound the command also to
146 Also affected files lib/silcclient/client_channel.c,
147 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
149 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
151 * Added silc_rng_get_byte_fast function in to the
152 lib/silccrypt/silcrng.[ch].
154 * Changed the interface of silc_packet_assemble and the
155 silc_packet_send_prepare. If silc_packet_assmble is now
156 called the application does not call silc_packet_send_prepare
157 because the library will call it automatically. These
158 interfaces now also return a reference to the outgoing buffer
159 which includes the assembled packet, which the application can
160 use to encrypt the packet.
162 Affected files are lib/silccore/silcpacket.[ch],
163 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
164 silcd/packet_send.c, server_backup.c and packet_receive.c.
166 * Fixed a packet sending bug on very high load, where outgoing
167 packet queue wasn't handled correctly and packets got corrupted.
168 Affected files are lib/silcutil/*/silc*sockconn.c,
169 lib/silcclient/client.c and silcd/server.c.
171 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
173 * Added macro SILC_PACKET_DATALEN which can be used during
174 packet assembling to check whether the data to be added to
175 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
176 len is truncated until it fits it.
178 Added checks for maximum length of channel message payload and
179 private message payload also.
181 Added checks for maximum packet length in server and in
184 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
185 lib/silcclient/client.c, lib/silccore/silcchannel.c and
186 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
187 lib/silcclient/client_prvmsg.c.
189 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
191 * Added silc_server_packet_queue_purge call to the
192 silc_server_disconnect_remote to assure that all data in the
193 queue before disconnecting is sent to the network. Affected
196 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
198 * Added the deleting of server's own ID cache entry to the
199 silc_server_free function. Free also everything else that
200 has been allocated in silc_server_init. The affected file
203 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Added functions silc_parse_version_string, silc_version_to_num,
206 and silc_ske_parse_version to parse SILC protocol style version
207 strings. Affected files lib/silcutil/silcutil.[ch] and
208 lib/silcske/silcske.[ch].
210 * Added new configuration params: version_protocol, version_software
211 and version_software_vendor to specify what version the remote
212 host must at least be to be able to connect to server. The vendor
213 string can be regex matched too. Added new function
214 silc_server_connection_allowed to check maximum number of allowed
215 connections, and allowed versions for incoming connections.
216 Affected files are silcd/server.c, server_util.[ch] and
219 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Added preliminary support for signals in scheduler. The
222 signals we care about are now blocked always when the scheduler
223 is locked. This way we can synchronise the use of signal with
224 scheduler. It is guaranteed that when signal occurs the scheduler
225 is not locked, and thus new tasks can be safely added to the
228 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
229 to silc_schedule_internal_init and silc_schedule_internal_uninit.
230 Added new platform specific routines
231 silc_schedule_internal_signals_[un]block and
232 silc_schedule_internal_signal_[un]register.
234 Added new functions to SILC Schedule API:
235 silc_schedule_signal_[un]register. Each signal that application
236 is going to use should be registered to the scheduler.
238 Affected files are lib/silcutil/silcschedule.[ch],
239 lib/silcutil/*/silc*schedule.c.
241 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Check for unauthenticated client and server in the
244 silc_server_new_client and silc_server_new_server functions.
245 Affected file silcd/packet_receive.c.
247 * Added function silc_string_is_ascii to check whether given
248 string is 7-bit ASCII string. Affected files are
249 lib/silcutil/silcutil.[ch].
251 * Added function silc_id_is_valid_server_id into the
252 silcd/serverid.c and added checking for valid Server ID's in
253 silc_server_new_server. The Server ID must always be based
254 on the server's public IP address.
256 * Added logging of DISCONNECT packet message in the server.
257 Affected file silcd/server.c.
259 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
261 * Changed all library interfaces that use Global RNG to also
262 accept SilcRng as argument. Affected files are
263 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
264 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
265 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
266 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
269 * Added function silc_pkcs_generate_key to the
270 lib/silccrypt/silcpkcs.[ch] for applications so that they
271 don't need to do pkcs->pkcs->init calls anymore.
273 * Remove SilcSocketConnection from the SFTP API since it really
274 wasn't needed there. The application has the information
275 saved in its contexts anyway and the SFTP layer doesn't need
276 know about it. Affected files lib/silcsft/silcsftp.h and
277 lib/silcsftp/sftp_[server/client].c.
279 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
280 The SilcSimContext is not SilcSim.
282 * Fixed possible buffer overflows in silc_id_render in the
283 lib/silcutil/silcutil.c.
285 * On EPOC the global crypto module lists are not used at all
286 in the crypto library. Added support for using the constant
287 algorithm list on EPOC. Affected files are
288 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
291 * Fixed the handling of third parameter of KICKED notify, since
292 it was mistakenly updated to SILC Protocol 1.0 even though it
293 is to be included in 1.1. Since it is not in 1.0 it is not
294 mandatory, and this fix now handles it only if it is provided,
295 and it is not error if it is not provided. Affected file
296 lib/silcclient/client_notify.c.
298 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
300 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
301 client. Affected file irssi/src/silc/core/client_ops.c.
303 * Merged with Irssi 0.8.4 from irssi.org CVS.
305 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
307 * Check for valid socket connection in client entries before
308 sending any messages. Fixes a crash, but doesn't fix some
309 other underlaying bug that is lurking there. Affected
310 file silcd/packet_send.c.
312 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
314 * $usermode, $cumode and $cumode_space expandos shouldn't do
315 anything with non-SILC server records. Affected file
316 irssi/src/silc/core/silc-expandos.c
318 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
320 * Fixed the silc_net_check_[host/local]_by_sock to support
321 IPv6 bound sockets as well. Now they can return IPv6 addresses
322 as well. Affected file lib/silcutil/silcnet.c.
324 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
325 Affected lib/silcutil/unix/silcunixnet.c.
327 * Fixed ID rendering (at least on some platforms, not NetBSD)
328 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
330 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
332 * Added silc_hash_public_key and silc_hash_public_key_compare
333 functions to be used with SilcHashTable. They can be used to
334 hash public keys and compare public keys in hash table. Affected
335 file lib/silcutil/silcutil.[ch].
337 * Added support for specifying multiple public keys for Client
338 connection section in server configuration file. This makes it
339 possible to accept multiple public keys from same host, or to
340 make a section that accepts any incoming host, and have the
341 accepted public keys listed in the section.
343 Added functions silc_sever_[find/get]_public_key, added the
344 support for this actually to all connection sections but only
345 the Client section is currently allowed to specify multiple
348 Affected files are silcd/server.c, server_internal.h,
349 command.c, protocol.c, server_util.[ch], packet_receive.c.
351 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
353 * Merged Irssi 0.8.2 from irssi.org CVS.
355 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
357 * If silc_debug is TRUE, also output standard logging messages
358 to stderr with the debug output.
360 Made silc_log_reset_all() flushing all channels before returning.
361 Also fixed some documentation typos.
363 Affected files are lib/silcutil/silclog.[ch].
365 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Fixed the server to check correctly the amount of connections
368 from single host, by checking also the type of the connection.
369 Fixed also the comparison of number of connections and number
370 of allowed connections. Affected files are silcd/server.c,
373 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
375 * Fixed the USERS command reply to save the user's mode on the
376 channel as well. Fixed JOIN command reply to check whether a
377 client is on channel already and not join it twice. Affected
378 file lib/silcclient/command_reply.c.
380 * Added new file silc-expandos.c into irssi/silc/core/ to return
381 various stuff for various signal for the statusbar etc. updating.
382 Now Irssi SILC client prints channel user modes etc. on the
385 * The user mode (like server/router operator changes) is now shown
386 on the Irssi SILC client's statusbar. The affected files are
387 irssi/src/silc/core/client_ops.c, silc-expandos.c.
389 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
391 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
392 to SILC_SCHEDULE_[UN]LOCK macros.
394 * Added more error printing to logs in server code. Affected
395 files silcd/server.c and silcd/protocol.c.
397 * Fixed -S option parsing in Irssi SILC Client. Affected file
398 irssi/src/silc/core/silc-core.c.
400 * Added silc_buffer_alloc_size function. Affected file is
401 lib/silcutil/silcbuffer.h.
403 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
406 constants. Affected files in
407 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
410 * Changed the internal SFTP Memory FS table to const. Affected
411 file lib/silcsftp/sftp_fs_memory.c.
413 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
415 * Fixed the buffer formatting and unformatting routines to
416 check the size of 64 bits types with sizeof(). Affected
417 file is lib/silcutil/silcbuffmt.c.
419 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Removed 0.6.x backwards support.
423 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
425 * Changed all integer type names:
426 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
427 to avoid collisions with other libraries using same type names
430 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
432 * Added `prefer_ipv6' argument to the functions
433 silc_net_gethostbyname[_async]. If it is TRUE it will return
434 IPv6 address over IPv4. If FALSE IPv4 address is returned
435 even if IPv6 address was found. Affected files
436 lib/silcutil/silcnet.[ch].
438 * Added support silc_net_create_connection[_async] to fallback
439 to IPv4 address if IPv6 address could not be used (like if
440 it doesn't work on a specific system). Affected file in
441 lib/silcutil/unix/silcunixnet.c.
443 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
445 * Added silc_schedule_reinit function to do the enlarging
446 of the max tasks handling capabilities of the scheduler.
447 Affected files lib/silcutil/silcschedule.[ch].
449 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
451 * Added automatic extern "C" { ... } for C++ compilers so the
452 application does not need to define them. Affected file
453 includes/silcincludes.h.
455 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
456 old name went against naming convention. Applications now
457 include "silcclient.h" instead of "clientlibincludes.h".
458 Removed includes/clientlibincludes.h, it is redundant now.
460 * Renamed includes/version.h to silcversion.h.
462 * Added really preliminary support for OS/2 into the util
463 library. Only thread & mutex API is implemented, others
464 are still to be implemented. Created the lib/silcutil/os2/
465 directory. Created also file includes/silcos2.h.
467 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
469 * Added preliminary BeOS support into the util library.
470 Created lib/silcutil/beos/, and implemented all the needed
471 functions to support SILC on BeOS. Created also file
474 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
476 * Added proper initializations to silc's irssi code, so it's
477 now possible to load it as module. Affected files
478 irssi/src/silc/core/silc-core.c,
479 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
481 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
483 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
486 * Fixed the silcdoc document generator to correct generate
487 docs from all kinds of filenames. Affected files are
488 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
490 * ROBOdoc documented lib/silcutil/silcmemory.h.
491 Added also new function silc_memdup.
493 * Removed lib/silcutil/silcbufutil.h and moved those routines
494 to the lib/silcutil/silcbuffer.h.
496 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
498 * Added `user_count' to the SilcChannelEntry which now tells the
499 number of users on the channel. The user count is now saved
500 in normal server of global channels as well. Affected files
501 silcd/server.c, idlist.h, packet_receive.c and command.c.
503 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
504 include file utility functions.
506 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
507 instead of calling directly OS routines.
509 * Fixed NICK change printing in Irssi SILC Client. Fixed
510 KICKED notify printing in Irssi SILC Client. Affected file
511 irssi/src/silc/core/client_ops.c.
513 * Fixed a NICK change bug in client library, to not recreate the
514 client_entry->channels hash table everytime nick is changed.
515 Affected file lib/silcclient/client.c.
517 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * ROBOdoc documented the lib/silcske/silcske.h, and improved
520 the SKE interface a bit.
522 * Fixed padding problem in PKCS#1. The padding was not actually
523 random since the random number generator was used incorrectly.
524 This security bug affects only when encrypting with PKCS#1, and
525 it is not currently used at all in SILC. SILC only use signing
526 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
528 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
530 * Rewrote the notify handling in Irssi SILC client to not call

540 key_exchange_timeout, conn_auth_timeout, connections_max,
543 Implemented all the new config settings handling in the server.
545 Optimized the use of SKE Mutual flag usage. Use it only
546 if connection authentication protocol is not based in public
549 Renamed all SilcServerConfigSection* to SilcServerConfig*
550 to have a bit shorter names.
552 Affected files silcd/serverconfig.[ch], server.[ch], and
555 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

592 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
594 * Added new configuration options and blocks:
595 keepalive_secs, reconnect_count, reconnect_interval,
596 reconnect_interval_max, reconnect_keep_trying and
597 require_reverser_lookup. Added ConnectionParam block, and
598 implemented the connection parameters when connecting as
599 initiator and when accepting connections as responder.

602 whether given configuration value has been given already.
604 Affected files silcd/serverconfig.[c], server.[c].
606 * Splitted the doc/example_silcd.conf.in. Separated the crypto
607 algorithm parts and created new file silcalgs.conf, that
608 is now included from the example_silcd.conf.in.
610 * Optimized the silc_server_connect_to_router_second to take
611 the connection configuration object from the SilcServerConnection
612 object instead of finding it during the connecting phase.
613 Added the configuration object to SilcServerConnection struct.
614 Affected files silcd/server_internal.h, server.c.
616 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

628 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Unified the serverconfig.[ch]'s helper function interface.
631 Affected file silcd/serverconfig.[ch].
633 * Removed doc/example_silc.conf.in since it is redundant.
634 The make install will now install irssi/silc.conf file.
636 * Added new Passphrase and Publickey authentication methods to
637 config file, allowing both public key and passphrase based
638 authentication to be set at the same time.
640 Added `prefer_passphrase_auth' setting in config file which
641 can be used to set to prefer passwd auth if both passwd and
642 public key is set. If not set, public key is preferred.
643 This has effect only when being initiator (responder will try
646 Added support for authentication with passphrase and public key
647 at the same time. The passphrase is tried first always since
648 it is faster to check.
650 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
652 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
654 * Merged the new SILC Config library, with the server parsing
655 support. Read the header file silcconfig.h or the toolkit
656 documentation for the news. Affected files are

690 * Fixed CUMODE_CHANGE notify handling to change the mode of
691 correct client. Affected file lib/silcclient/client_notify.c.
693 * Make silc_rng_alloc fail if it cannot allocate the sha1
694 hash algorithm. Affected file lib/silccrypt/silcrng.c.
696 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
698 * Fixed the file transfer's key agreement payload to include
699 zero port also if the hostname is NULL because it could not
702 Call file transfer monitor callback now also if error occurs
703 during key agreement protocol.
705 Changed the silc_client_file_send interface to return the
706 SilcClientFileError instead of session id. The session ID
707 is returned into pointer provided as argument.
709 Check that the file exists locally before sending the
710 file transfer request at all.
712 Affected file lib/silcclient/client_ftp.c, silcapi.h.
714 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

722 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
723 SILC_LOG_WARNING to give out Warning and not Error. Affected
724 file lib/silcutil/silclog.c.
726 * Fixed the channel message payload decryption in the function
727 silc_channel_message_payload_decrypt to not modify the original
728 buffer before it is verified that the message decrypted
729 correctly. Otherwise, next time it is called with correct
730 channel key it won't encrypt since the payload is corrupted.
731 Affected file lib/silccore/silcchannel.c.
733 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

745 * Fixed a bug in hash table internal routine for traversing
746 the table with foreach callback. The current entry may
747 become invalid in the callback but it was referenced after
748 the callback returned.
750 Do not allow auto rehashing of hash table during the
751 silc_hash_table_foreach operation, for same reasons as it is
752 not allowed for SilcHashTableList. Affected files are
753 lib/silcutil/silchashtable.[ch].
755 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Defined DLLAPI into silcincludes.h and silcwin32.h for

761 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Fixed private message handling. It used some old code that
764 caused the client to crash. Affecte file is
765 lib/silcclient/client_prvmsg.c.
767 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
769 * Added function silc_client_add_channel,
770 silc_client_replace_channel_id, and removed functions
771 silc_client_new_channel_id and silc_idlist_get_channel_by_id
774 * Added cross reference of the joined channels to the
775 SilcClientEntry, and changed the SilcChannelEntry's
776 users list to SilcHashTable. The affected files are
777 lib/silcclient/idlist.[ch].
779 * Fixed a bug in hash table tarversing. While the hash table
780 is traversed with SilcHashTableList the table must not be
781 rehashed. It is now guaranteed that auto rehashable tables
782 are not rehashed while tarversing the list. Also defined that
783 silc_hash_table_rehash must not be called while tarversing
784 the table. Added function silc_hash_table_list_reset that must
785 be called after the tarversing is over. The affected files are
786 lib/silcutil/silchashtable.[ch].
788 * Changed all hash table traversing to call the new
789 silc_hash_table_list_reset in server and in client library.
791 * Added function silc_client_on_channel to return the
792 SilcChannelUser entry if the specified client entry is joined
793 on the specified channel. This is exported to application as
794 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
796 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
798 * Fixed founder regaining problem with JOIN command on normal
799 server. The notify for mode change must be sent always and
800 not only if !cmd->pending. Affected file silcd/command.c.
802 * Fixed the WHOWAS command's reply sending to support the
803 lists correctly. Affected file silcd/command.c.
805 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
807 * When sending JOIN command to router for processing the
808 sender's old command identifier was not saved back to the
809 sender's command context, fixed now. The affected file is
812 * Create the key in JOIN command of the router did not return
813 the channel key, added check for this. Affected file is
816 * Fixed a channel ID update bug in JOIN command reply. Do
817 not directly upgrade the ID but call the function
818 silc_idlist_replace_channel_id if the ID was changed.
819 Affected file silcd/command_reply.c.
821 * Fixed memory leaks from command calling if it would fail.
822 Affected file silcd/command.c.
824 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

828 Memory leak fixes around libaries, irssi window resize fix,
829 new silclist.h and silcdlist.h, all extern inline changed to
832 * Removed dotconf from lib/dotconf, not needed anymore.
834 * Removed TRQ from lib/trq, not needed anymore.
836 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
837 with server connections. Later this will be configurable
838 in config file after new config file is done. Affected file
841 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Fixed a crash in server related to channel announcements.
844 Affected file silcd/server.c.
846 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
848 * Fixed memory leaks in silc_server_create_new_channel*
849 functions. Affected file silcd/server.c.
851 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
852 which ID was changed. This way the router will send the
853 user list for the channel again, and server won't be in
854 desync in some rare circumstances. Affected file is
855 silcd/packet_receive.c.
857 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
859 * Check for NULL socket pointer in the function

868 * Fixed some header addition to Toolkit distribution in
869 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
871 * Added lib/silcclient/client_ops_example.h as an template
872 file for application programmers to quickly start using
873 the SilcClientOperation functions in their application.
874 Updated the lib/silcclient/README as well to tell about this
875 nice file made available.
877 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Call silc_server_remove_from_channels when removing client
880 entry when NO_SUCH_CLIENT_ID was received. Affected file
881 is silcd/command_reply.c.
883 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
885 * Added server & router operator statistics updating. Affected
886 file silcd/packet_receive.c and silcd/command.c.
888 * Fixed the SERVER_SIGNOFF notify handling on normal server
889 not to save the history information for clients. Same was
890 fixed earlier in remove_clients_by_server function, but not
891 here. Affected file silcd/packet_receive.c.
893 * Raised the default connection-retry count from 4 to 7 in
894 server. Affected file silcd/server.h.
896 * Cancel any possible reconnect timeouts when we start the
897 key exchange. Affected file silcd/server.c.
899 * Do not reconnect on connection failure when SCONNECT was
900 given. Affected files silcd/server.[ch].
902 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
904 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
906 * Fixed the NICK command to always give the unformatted
907 nickname to the one giving the NICK command. If unformatted
908 nickname is cached already it will be formatted and the
909 local entry will always get the unformatted nickname.
910 Affected file lib/silcclient/idlist.c.
912 * Fixed some double frees from client library commands.
913 Affected file is lib/silcclient/command.c.
915 * Fixed CUMODE command in server to assure that no one can
916 change founder's mode than the founder itself, there was a
917 little bug. Affected file silcd/command.c.
919 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
921 * Removed the SilcClientCommandDestructor from the client
922 libary, it is not needed anymore. Affected files are
923 lib/silcclient/silcapi.h, command[_reply].[ch],
924 client_notify, idlist.c.
926 * Fixed GETKEY command to first resolve client, and then
927 resolve the server only if the client was not found, instead
928 of resolving both at the same time. Affected file is
929 lib/silcclient/command.c.
931 * Added silc_client_start_key_exchange_cb and lookup the
932 remote hostname and IP address before starting the key
933 exchange with server. The affected file is
934 lib/silcclient/client.c.
936 * The server's public key is now saved using the IP address
937 of the server and not the servername for the filename.
938 The hostname public key filename is checked as an fall back
939 method if the IP address based filename is not found.
941 Fixed the GETKEY command to save the fetched server key
944 Print the remote server's hostname now when new key is
945 received during connection process. Affected file is
946 irssi/src/silc/core/client_ops.c.
948 * Return always our own public key to the client if it asks
949 for it with GETKEY command. Affected file silcd/command.c.
951 * Removed the use_auto_addr variable from default config
952 file since it was in wrong section. Affected file is
955 * Fixed TOPIC_CHANGE notification to not route it when it
956 was sent using silc_server_send_notify_to_channel function.
957 Affected file silcd/command.c.
959 * Fixed silc_server_send_notify_kicked to send the kicker's
960 Client ID also, it was missing. Affected files are
961 silcd/command.c, silcd/packet_send.[ch].
963 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
965 * Do not save client history information in SERVER_SIGNOFF.
966 Fixes the bug in normal server that it does not detect
967 the client becoming valid after the server becomes back
968 online. Affected file silcd/server_util.c.
970 * Added `sock_error' field into the SilcSocketConnection
971 context. When error occurs during socket operation (read
972 or write) the error is saved. Added also new function
973 silc_socket_get_error to return human readable socket error
974 message. Affected files are lib/silcutil/silcsockconn.[ch],
975 lib/silcutil/unix/silcunixsockconn.c, and
976 lib/silcutil/win32/silcwin32sockconn.c.
978 * The server now prints the socket error message in the
979 signoff for client. Affected file silcd/server.c.
981 * Fixed the `created' channel information sending from router
982 to server in JOIN command. Checks now whether the channel
983 really was created or not and set it according that.
985 Fixed the JOIN command to use the client entry's current
986 ID during the joining procedure instead of the one it sent
987 in the command (it is checked though), since it can change
988 between the packet processing and command processing, and
989 would just case unnecessary pain in the client end. Affected
990 file silcd/command.c.
992 * Fixed a channel key payload sending to use correct channel
993 ID when the server was forced to change the channel's ID by
994 router. Router sent the key payload with the old Channel ID.
995 Affected file silcd/packet_receive.c.
997 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
999 * Call silc_server_save_channel_key only if the key payload
1000 was provided in the JOIN command's command reply. Affected
1001 file silcd/command_reply.c.
1003 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed silc_mp_sizeinbase to return the value correctly with
1006 MPI. Affected file lib/silcmath/mp_mpi.c.
1008 * Fixed the stop_server signal to correctly stop the scheduler
1009 and gracefully stop the server when SIGTERM or SIGINT signals
1010 are received. Affected file silcd/silcd.c.
1012 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1014 * Simple handling of TERM and HUP signals. Also added some log
1015 flushing call around. Affected file is
1018 * Fixed small bugs in silclog.c. Now buffering output will take
1019 effect after 10 seconds since startup: This will ensure that
1020 no important startup messages are lost. Also output redirection
1021 will preserve original format ([Date] [Type] message).
1022 Affected file is lib/silcutil/silclog.c.
1024 * Added two options to the config file, in the logging section:
1025 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1026 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1028 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1030 * Do not print the warning about log files not being initialized
1031 more than once to avoid excess logging. Affected file is
1032 lib/silcutil/silclog.c.
1034 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1035 the SIM copying in make install in Makefile.am.pre.
1037 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1039 * Rewritten silclog APIs. Globally interesting changes follows:
1040 silc_log_set_files() changed to silc_log_set_file().
1041 silc_log_set_callbacks() changed to silc_log_set_callback().
1042 ROBOdoc documented silclog header file.
1043 SilcLogCb now returns bool to wether inihibit the default
1044 handler or not (to keep the old behaviour return always TRUE).
1045 The new APIs should also fix the problem of the
1046 silcd_error.log file that was written in the current directory.
1049 Log files streams will remain opened after silc_log_set_file()
1050 call, means less CPU usage notably on high traffic servers.
1051 File streams are now full buffered, and flushed to the disk
1052 every 5 minutes, lesses HD activity and CPU usage.
1053 Messages can be redirected, allowing admins to configure
1054 one single logfile for all server messages.
1055 the silc_log_quick global variable to activate fast-logging.
1056 Affected files lib/silcutil/silclog.[ch]
1058 * Changed some code to conform new silclog APIs. Affected
1059 files are doc/example_silcd.conf.in, silcd/server.c
1060 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1063 * Fixed a memory leak that could occur in some situations.
1064 Affected file silcd/serverconfig.c.
1066 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1068 * Added the silc_client_del_client to remove the client from
1069 all channels as well. Affected file lib/silcclient/idlist.c.
1071 * Fixed the client library to correctly remove the client
1072 from all channels when the client entry is being destroyed.
1073 Affected file lib/silcclient/client_notify.c, command.c.
1075 * Added auto-nicking support to the client library. If the
1076 applicatio now sets client->nickname it will be sent to the
1077 server after connecting by the library. This way for example
1078 SILCNICK (or IRCNICK) environment variables will have effect
1079 and always change the nickname automatically to whatever
1080 it is wanted. Affected file lib/silcclient/client.[ch].
1082 * Renamed silc_server_command_bad_chars to the
1083 silc_server_name_bad_chars and moved it to the
1084 silcd/server_util.[ch]. Added also new function
1085 silc_server_name_modify_bad to return nickname that
1086 includes bad characters as new nickname without those
1087 bad characters. This check and modify is now used in
1088 silc_server_new_client when the username is initially set
1089 as nickname, so it must be checked to be valid nickname.
1090 Affected file silcd/packet_receive.c.
1092 * The nickname length is now taken from the packet for real
1093 and not trusted to strlen() since it clearly can return
1094 wrong length for nickname including bad characters. This
1095 also applies to channel names. Affected file silcd/command.c.
1097 * Removed the lib/silcsilm/modules directory. Modules are now
1098 compiled into the lib/silcsim. Fixed the copying of the
1099 modules to follow symbolic links in Makefile.am.pre.
1101 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1103 * Fixed silc_string_regexify list creation. Fixes bugs with
1104 BAN and INVITE commands in server. The affected file is
1105 lib/silcutil/unix/silcunixutil.c.
1107 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Removed the command destructor entirely from the server's
1110 command and command reply routines. It is not needed, and
1111 its usage was buggy and caused crashes. Affected files are
1112 silcd/command[_reply].[ch].
1114 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1116 * Cancel protocol and NULL sock->protocol if timeout
1117 occurred during protocol. Affected file silcd/server.c.
1119 * Cancel protocol timeouts always before calling the final
1120 callback, to assure that after final callback is called
1121 no other state will be called for the protocol anymore.
1122 Affected file silcd/protocol.c.
1124 * Print error log if incoming connection configuration could
1125 not be found. Affected file silcd/server.c.
1127 * Fixed JOIN command to correctly save the founder mode
1128 to the client on normal SILC server, when the channel
1129 was created by the router. Affected file silcd/command.c.
1131 * Fixed LIST command (hopefully) to send correct reply
1132 packets. Affected file silcd/command.c.
1134 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1136 * The silc_packet_receive_process now returns FALSE if the
1137 read data was invalid packet, and TRUE if it was ok.
1139 The server now checks that if unauthenticated connection
1140 sends data and its processing fails the server will close
1141 the connection since it could be a malicious flooder.
1143 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1145 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Make sure the warning about error opening a log file is
1148 printed only once and not everytime it fails (produces
1149 too much useless log). Affected file lib/silcutil/silclog.c.
1151 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1153 * Made the silc_server_daemonise() function more readable.
1154 Affected file silcd/server.c.
1156 * Pid file is now optional, the user may comment it out from
1157 the config file. Removed define SILC_SERVER_PID_FILE, we
1158 don't need a default any longer. Affected file
1159 configure.in.pre, lib/Makefile.am.pre.
1161 * Make some use of the pid file. The server now dies at startup
1162 if it detects a valid pid file on his path. The server would
1163 die anyway in this circumstance, because of the bind() failure.
1164 Affected file silcd/silcd.c.
1166 * No longer compiling lib/dotconf.
1168 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1170 * Fixed JOIN command parsing not to crash. Affected file
1171 lib/silcclient/command.c.
1173 * Fied the NICK_CHANGE notify to add the new client entry
1174 even it is resolved. This removes an <[unknown]> nick
1175 thingy bug in the client. Affected file is
1176 lib/silcclient/client_notify.c.
1178 * Do not try to allocate 0 bytes (efence does not like it)
1179 in lib/silccore/silccomand.c when encoding payload.
1181 * Do not take IRCNICK as nickname in Irssi SILC client since
1182 it is not possible to set nickname before hand connecting
1183 the server (TODO has an entry about adding auto-nicking
1186 * Changed the silc_server_command_pending to check whether
1187 there already exists an pending entry with the specified
1188 command, command identifier and pending callback. This is
1189 to fix IDENTIFY and WHOIS related crashes that may register
1190 multiple pending commands with same identifier. Affected
1191 file silcd/command.c.
1193 * Fixed the server to reconnect to the router even if it
1194 was already reconnecting and EOF was received. This to
1195 fix a possibility that the server wouldn't ever try to
1196 auto-reconnect to the router. Affected file silcd/server.c.
1198 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1200 * Fixed the server's password authentication to use the
1201 length of the locally saved password, and not the one
1202 sent in the packet. Affected file silcd/protocol.c.
1204 * Fixed same password authentication problem in the
1205 Authentication Payload handling routines in
1206 lib/silccore/silcauth.c.
1208 * Yet another password authentication problem fixed with
1209 channel password handling in silcd/command.c.
1211 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1213 * If first character of string in silc_parse_userfqdn is '@'
1214 then do not parse it. Affected file is
1215 lib/silcutil/silcutil.c.
1217 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Fixed minor bug in IDENTIFY command reply sending, which
1220 caused various weird problems during JOIN when it was
1221 resolving names for users. Affected file silcd/command.c.
1223 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1225 * Fixed the IDENTIFY command reply sending to chech better valid
1226 clients. It was possible to send incomplete list of replies.
1227 Affected file silcd/command.c.
1229 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1231 * Added silc_client_command[s]_[un]register functions now to
1232 dynamically register the commands in client library. Removed
1233 the static table of commands. This allows the client library
1234 to call commands without causing the application to know about
1235 what commands library has called.
1237 Removed the INFO command reply kludge to detect when the command
1238 was called by library. Now library use its own command reply
1239 function for INFO command.
1241 Added function silc_client_command_call to call a command.
1242 Application can use it to call command, not access the structure
1245 Now all commands that are sent by the client library (not
1246 explicitly sent by application) use own command reply functions.
1248 Affected files around lib/silcclient/ and in
1249 irssi/src/silc/core/.
1251 * Fixed the WHOIS command reply sending to chech better valid
1252 clients. It was possible to send incomplete list of replies.
1254 Fixed the WHOIS and IDENTIFY to send the request to router
1255 if normal server did not do it and did not find any results.
1257 Affected file silcd/command.c.
1259 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1261 * Moved the internal data from SilcClient context into its
1262 own file, not accesible to application. Affected files
1263 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1264 and other files in client library.
1266 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1268 * Added doc/examples installation target in Makefile.am.pre.
1271 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1274 commands the found client entry will be removed from the
1275 cache, after notifying application about the error. Affected
1276 file lib/silcclient/command_reply.c.
1278 * Changed the /MSG to check for exact nickname user gave, and
1279 not let `nick' match `nick@host' if it is only one found. Now,
1280 user must type the exact nickname (like nick@host2) even if
1281 there are no more than one same nicks found. This is to avoid
1282 a possibility of sending nickname to wrong nickname since
1283 `nick' could match `nick@host'. Affected file is
1284 irssi/src/core/silc-servers.c.
1286 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Do not print "you are now server operator" or similar when
1289 giving /away command. Affected files are
1290 irssi/src/silc/core/client_ops.c, silc-servers.h.
1292 * Made the silc_server_command_pending_error_check to send
1293 the same command reply payload it received back to the
1294 original sender of the command. This way all arguments
1295 that was received by the server will be received by the
1296 client too. Affected file silcd/command.c.
1298 * Added the silc_idcache_add to return the created cache entry
1299 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1301 * Add global clients to expire if they are not on any channel.
1302 This is because normal server will never know if they signoff
1303 if they are not on any channel. The cache expiry will take
1304 case of these entries. This is done by normal servers only.
1305 The affected files are silcd/command_reply.c,
1306 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1308 * If server receives invalid ID notification for WHOIS or
1309 IDENTIFY and the ID exists in the lists, it is removed.
1310 Affected file silcd/command_reply.c.
1312 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1313 in client then client entry that it matches is searched and
1314 the nickname is printed on the screen for user. Affected
1315 file irssi/src/silc/core/client_ops.c.
1317 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Use cache entry expire time in the LIST command reply to
1320 purge old entries from the cache after the LIST command
1321 reply has been received. This way we don't have non-existent
1322 entries in the cache for too long. Affected file is
1323 silcd/command_reply.c.
1325 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * If we are normal server, and we've not resolved client info
1328 in WHOIS or IDENTIFY from router, and it is global client,
1329 we'll check whether it is on some channel. If it is not
1330 then we cannot be sure about its validity and will resolve it
1331 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1332 file silcd/command.c.
1334 * Search channel by name (if possible) rather than by ID
1335 in IDENTIFY command's command reply. Affected file is
1336 silcd/command_reply.c.
1338 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1341 Updated specs and implemented it. Affected file silcd/command.c,
1342 silcd/packet_send.c and silcd/packet_receive.c.
1344 * Implemented the <founder auth> payload handling in the JOIN
1345 command. If provided all conditions for channel joining
1346 except requirement to provide correct passphrase can be
1347 overrided by the channel founder. Updated the protocol specs.
1348 Affected file silcd/command.c.
1350 Added support for founder auth in JOIN command in client
1351 library. Fixed the parsing of the JOIN command now to support
1352 all options as they should be. The affected file is
1353 lib/silcclient/command.c.
1355 * Optimized the WHOIS and IDENTIFY commands to send the request
1356 to router only if it includes nicknames or other names. If
1357 they include only IDs then check the local cache first before
1358 routing. Affected file is silcd/command.c.
1360 * Added channels topic announcements. Affected file is
1361 silcd/packet_receive.c and silcd/server.c.
1363 * Fixed the silc_server_send_notify_topic_set to really destine
1364 the packet to channel. Affected file silcd/packet_send.c.
1366 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1367 library. Affected file lib/silcclient/client_notify.c.
1369 * Added UMODE announcements. Affected file silcd/server.c.
1371 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Memory leak fixes in:
1375 lib/silcutil/silcsockconn.c
1376 lib/silcske/silcske.c
1377 lib/silcske/groups.c
1379 lib/silccrypt/silcpkcs.c
1380 lib/silccore/silccommand.c
1381 lib/silccore/silcidcache.c
1386 * ROBOdoc documented the lib/silcske/groups.h file and a
1387 bit changed the interface for better.
1389 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1391 * Update the client entry context in the ID cache after
1392 nick change. Affected file lib/silcclient/command.c.
1393 Fixes the CUMODE command when regaining founder privileges,
1394 and a little WHOIS problem.
1396 * Fixed silc_net_gethostbyname to correctly call the
1397 inet_ntop. Affected file lib/silcutil/silcnet.c.
1399 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1401 * Added IPv6 support checking to the configure.in.pre, added
1402 also --enable-ipv6 option to override the check. Affected
1403 file configure.in.pre.
1405 * The silc_thread_create now calls the start function
1406 directly if threads support is not compiled in. Removes
1407 ugly #ifdef's from generic code. Affected files are
1408 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1410 * Added silc_net_gethostby[name/addr]_async to asynchronously
1411 resolve. Affected files are lib/silcutil/silcnet.[ch].
1413 * Added support for rendering IPv6 based server, client and
1414 channel IDs. Affected file lib/silcutil/silcutil.c.
1416 * Added support for creating IPv6 based server IDs. Affected
1417 file is silcd/serverid.c.
1419 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1421 * Added silc_net_gethostby[addr/name] into the
1422 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1423 routines. Added silc_net_is_ip[4/6]. Affected file is
1424 lib/silcutil/unix/silcunixnet.c. All routines that take
1425 address as argument now supports both IPv4 and IPv6 addresses.
1427 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1429 * Fixed LIST command reply sending in server. Affected file
1432 * Server now sends the kicker's client ID in the KICK notify
1433 to the kicked client. Affected file silcd/command.c.
1435 * The client library now parses the kickers client ID and
1436 UI displays it. Affected files lib/silcclient/client_notify.c
1437 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1439 * Made all payload parsing function prototypes consistent.
1440 They all take now const unsigned char * and uint32 pair as
1441 the payload data instead of SilcBuffer. Changes all around
1442 the source tree. Other unsigned char* -> const unsigned char*
1443 changes around the tree as well.
1445 * Optimized SFTP client and server packet sending not to
1446 allocate new buffer for each packet but to recycle the
1447 first allocated buffer. Affected files are
1448 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1450 * Optimized the SFTP client to use SilcList instead of
1451 SilcDList for requests, because it is faster. Affected file
1452 is lib/silcsftp/sftp_client.c.
1454 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1455 into lib/silccore/silcid.[ch].
1457 Renamed silcpayload.[ch] into silcargument.[ch].
1459 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * If client entry is deleted with active key agreement
1462 session, abort the session.
1464 The silc_client_abort_key_agreement now calls the completion
1465 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1467 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1470 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Don't use __restrict in older GCC's. Affected file is
1473 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1475 * silc_net_localhost now attempts to reverse lookup the
1476 IP/hostname. Affected file lib/silcutil/silcnet.c.
1478 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1479 command. It can be used to gain founder privileges at
1480 the same time when joining the channel.
1482 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1483 kicker's client ID as well. Updated protocol specs.
1485 Defined that the server must send SILC_COMMAND_IDENTIFY
1486 command reply with error status to client who sent
1487 private message with invalid client ID.
1489 Updated the protocol specification.
1491 * Added silc_server_send_command_reply to send any
1492 command reply. Affected file silcd/packet_send.[ch].
1494 * Added silc_id_payload_encode_data to encode ID payload
1495 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1497 * The server now send IDENTIFY command reply with error
1498 status if client ID in private message is invalid. Affected
1499 file silcd/packet_receive.c.
1501 * Save the server key file with server's IP address in
1502 the filename instead of hostname. The affected file is
1503 irssi/src/silc/core/client_ops.c.
1505 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1510 * Added libtool support for compiling shared objects in
1511 lib/silcsim. Affected file configure.in.pre and
1512 lib/silcsim/Makefile.am. Original patch by cras.
1514 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1516 * Pid file configuration, and server's config file fixes
1517 patch by toma. Updated CREDITS file.
1519 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Fixed silc_client_channel_message to not try to decrypt
1522 the message twice if it resolved the destination client
1523 information. This could cause of dropping one channel
1524 message. Affected file lib/silcclient/client_channel.c.
1526 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1529 lib/silcclient/client.c. This function is used when the SILC
1530 Client is run under some other scheduler, or event loop or
1531 main loop. On GUI applications, for example this may be
1532 desired to used to run the client under the GUI application's
1533 main loop. Typically the GUI application would register an
1534 idle task that calls this function multiple times in a second
1535 to quickly process the SILC specific data.
1537 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1539 * Fixed silc_server_drop() for dropping the supplementary
1540 groups as well, this could cause a security hole on some
1543 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1548 * Write PID file after dropping privileges. Added -F option
1549 to run server on foreground. A patch by debolaz.
1550 Affected files silcd/server.c, silcd/silcd.c.
1552 * Fixed MOTD to return the MOTD file server name. Affected
1553 file silcd/command.c.
1555 * Added INFO command reply handling to the Irssi SILC Client.
1556 Affected file irssi/src/silc/core/client_ops.c.
1558 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Fixed the silc_idcache_list_* routines to really support
1561 the dynamic list. Fixes a crash. Affected file is
1562 lib/silccore/silcidcache.c.
1564 * Fixed the LIST command reply to really call LIST command's
1565 pending callbacks. Affected file silcd/command_reply.c.
1567 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Update conn->local_entry->nickname after giving NICK
1570 command. Affected file lib/silcclient/command.c.
1572 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1574 * Added the [pid] option to the silcd configuration file
1576 Affected files: serverconfig.[ch] and silcd.c
1578 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Save fingerprint in WHOIS command reply in server.
1581 Affected file silcd/command_reply.c.
1583 * Fixed NICK commands pending callback registration.
1584 Affected file lib/silcclient/command.c.
1586 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Use ++server->cmd_ident when sending commands in server,
1589 instead of random number. Affected file silcd/command.c.
1591 * Fixed GETKEY command reply to call actually GETKEY pending
1592 command callbacks. Affected file silcd/command_reply.c.
1594 * A bit stricter check for nicknames. Check for same nickname
1595 in NICK command also. Affected file silcd/command.c.
1597 * Do not call INFO command everytime client ID changes, only
1598 during first connecting. Affected file lib/silcclient/client.c.
1600 * Set the new nickname only after successful command reply for
1601 NICK command is returned by server. Affected file
1602 lib/silcclient/command.c.
1604 * Remove nicknames from nicklist during server_signoff notify.
1605 Should fix /NAMES bit more. The affected file is
1606 irssi/src/silc/core/silc-channels.c.
1608 * Added `fingerprint' field to the SilcIDListData in the
1609 silcd/idlist.h to hold the fingerprint of the client's
1612 Send the fingerprint of the client's public key in WHOIS
1615 Affected files silcd/command.c, and silcd/idlist.[ch].
1617 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1618 create fingerprint from given data.
1620 * Show the fingerprint of the client's public key in WHOIS.
1621 Affected files irssi/src/module-formats.[ch] and
1622 irssi/src/silc/core/client_ops.c.
1624 * Format the multiple same nicknames also during JOIN and
1625 NICK_CHANGE notifys. Affected file is
1626 lib/silcclient/client_notify.c.
1628 * Do not print error on screen for invalid private message
1629 payload since it can come if someone is sending private
1630 messages with wrong key. Affected file
1631 lib/silccore/silcprivate.c.
1633 * Fixed multiple concurrent /PING crash. Affected file
1634 lib/silcclient/command.c.
1636 * Changed the wrong ID encoding. All IP addresses must be
1637 in MSB first order in encoded format. They were encoded
1638 wrong and was in LSB format. Affected files are
1639 silcd/serverid.c, lib/silcutil/silcutil.c.
1641 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1643 * Call the `connect' client operation through the scheduler
1644 in case of error. Affected file lib/silcclient/client.c.
1646 * Call the `failure' client operation even if the error
1647 occurred locally during a protocol. Affected file is
1648 lib/silcclient/protocol.c.
1650 * Added support of sending LIST command to router from normal
1651 server. This way normal server can get list of all channels
1652 in the network too. Fixed the channel list sending in the
1653 server too. Affected files are silcd/command.c, and
1654 silcd/command_reply.[ch].
1656 * Added silc_server_update_channels_by_server and
1657 silc_server_remove_channels_by_server. They are used during
1658 disconnection of primary router and in backup router protocol.
1659 Affected file silcd/server_util.[ch], silcd/server.c and
1660 silcd/server_backup.c.
1662 * Fixed channel adding to global list in IDENTIFY command
1663 reply in server. Affected file silcd/command_reply.c.
1665 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * If the incoming packet type is REKEY or REKEY_DONE process
1668 that packet always synchronously. Fixes yet another MAC
1669 failed error on slow (dialup) connections. Affected file
1670 lib/silcclient/client.c and silcd/server.c.
1672 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Call check_version SKE callback for initiator too. Affected
1675 file lib/silcske/silcske.c.
1677 * Implemented fix for security hole found in the SKE that was
1678 fixed in the specification few days back; the initiator's
1679 public key is now added to the HASH value computation.
1680 Added backwards support for the old way of doing it too, for
1681 old clients and old servers. Affected file is
1682 lib/silcske/silcske.c.
1684 * Enabled mutual authentication by default in SKE. If initiator
1685 is not providing mutual authentication the responder will
1686 force it. This will provide the proof of posession of the
1687 private key for responder. The affected files are
1688 lib/silcclient/protocol.c and silcd/protocol.c.
1690 * Do not cache anymore the server's public key during SKE.
1691 We do mutual authentication so the proof of posession of
1692 private key is done, and if the server is authenticated in
1693 conn auth protocol with public key we must have the public
1694 key already. Affected file silcd/protocol.c.
1696 * Added new global debug variable: silc_debug_hexdump. If
1697 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1698 file lib/silcutil/silclog.[ch].
1700 * Fixed compilation warning due to char * -> const char *.
1701 Affected files lib/silcutil/silcnet.h, and
1702 lib/silccore/silcauth.[ch].
1704 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1706 * Fixed CMODE command when new channel key was created. If
1707 the creation failed the old key was removed. Next time giving
1708 same command would crash the server since the old key was
1709 freed already. Affected file silcd/command.c.
1711 * Fixed the silc_server_announce_get_channels to not crash
1712 on reconnect. Affected file silcd/server.c.
1714 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1716 * Added silc_log_set_debug_string function to set a regex
1717 string to match for debug output. Only the function names,
1718 or filenames matching the given debug string is actually
1719 printed. This way it is possible to filter out those debug
1720 strings that user is not interested in.
1722 Fixed a bug in silc_string_regexify.
1724 Affected files lib/silcutil/silclog.[ch], and
1725 lib/silcutil/unix/silcunixutil.c.
1727 * Changed the -d options in both server and Irssi SILC client
1728 to take the debug string as argument. Affected files
1729 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1731 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Added silc_hash_babbleprint to create a Bubble Babble
1734 Encoded fingerprint. The encoding is developed by Antti
1735 Huima (draft-huima-babble-01.txt), and it creates human
1736 readable strings out of binary data. Affected file
1737 lib/silccrypt/silchash.[ch].
1739 * Print the babble print now in addition of fingerprint as well
1740 in Irssi SILC client. Affected files are
1741 irssi/src/fe-common/silc/module-formats.[ch],
1742 irssi/src/fe-common/silc/core/client_ops.c.
1744 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Fixed a security problem found in SKE. The initiator's
1747 public key too is now added to the HASH hash value creation
1748 which is signed by the responder to create the SIGN value.
1749 This will prevent anyone in the middle to lie to the responder
1750 about the initiator's public key. If this is done now, the
1751 man in the middle will get caught. Updated the protocol
1754 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * Better installation directory handling. Configure module
1757 paths and other paths automatically to example_silc* files
1758 in doc/. A patch by toma.
1760 * Fixed compiler warning from MPI library, and from SILC RNG.
1763 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1764 It can be configured with ./configure. A patch by toma.
1766 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Find correct make to use in prepare-clean. A patch by
1769 toma. Affected file prepare-clean.
1771 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1773 * Added irssi variables use_auto_addr, auto_bind_ip,
1774 auto_bind_port and auto_public_ip.
1776 * Changed the interface for silc_client_send_key_agreement
1777 in lib/silcclient/silcapi.h
1781 irssi/src/silc/core/silc-core.c
1783 lib/silcclient/silcapi.h
1784 irssi/src/silc/core/silc-channels.c
1785 lib/silcclient/client_keyagr.c
1788 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Added silc_pkcs_public_key_compare to compare two
1791 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1793 * Check that the client who set the founder mode on the
1794 channel is the same client that is giving the founder
1795 mode to itself. It is done by comparing the saved public
1796 key (it is saved even in the authentication is passphrase).
1797 Affected file silcd/command.c.
1799 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * Do not process packet for disconnected socket connection.
1802 Affected file lib/silccore/silcpacket.c.
1804 * Process the DISCONNECT packet through scheduler in the
1805 client library. Affected file lib/silcclient/client.c.
1807 * Fixed the silc_client_packet_parse to not to increase
1808 the packet sequence number if the conn->sock and the
1809 current socket connection is not same. This can happen
1810 for example during key agreement when the conn includes
1811 multiple socket connections (listeners). Affected file
1812 lib/silcclient/client.c.
1814 * The sender of the file transfer request now provides also
1815 the pointer (listener) for the key exchange protocol. If
1816 the listener cannot be created then it sends empty key
1817 agreement and lets the receiver provide the listener.
1819 Added `local_ip' and `local_port' arguments to the
1820 silc_client_file_send. If they are provided they are used,
1821 if not then it will attempt to find local IP address, if
1822 not found or bind fails then the remote client will provide
1825 Affected files are lib/silcclient/client_ftp.c and
1826 lib/silcclient/silcapi.h.
1828 * Extended the FILE SEND command to support defining the
1829 local IP and port for key exchange listener. They are
1830 optional. Affected file irssi/src/silc/core/silc-servers.c.
1832 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Defined to WHOIS command reply the sending of fingerprint
1835 of the client's public key (if the proof of posession of the
1836 corresponding private key is verified by the server).
1837 Updated to the protocol specification.
1839 * Added support of receiving the client's public key's
1840 fingerprint in command reply in client library. Affected
1841 file is lib/silcclient/command_reply.c, and
1842 lib/silcclient/idlist.[ch].
1844 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Do not send over 128 chars long nickname to the server
1847 in NICK command. Affected file lib/silcclient/command.c.
1849 * Do not send over 256 chars long channel names to the server
1850 in JOIN command. Affected file lib/silcclient/command.c.
1852 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Assure that silc_server_close_connection cannot be called
1855 twice for same socket context. Affected file is
1858 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Send error message to application if opening file for
1861 writing during file transfer fails. Affected file is
1862 lib/silcclient/client_ftp.c.
1864 Remove all file transfer sessions for a client that we're
1865 removing from ID cache.
1867 Affected file is lib/silcclient/client_ftp.c.
1869 * Fixed silc_net_addr2bin to return correct address. Affected
1870 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1872 * Fixed file transfer session removing on signoff notify.
1873 Affected file irssi/src/silc/core/silc-servers.c.
1875 * Added the SilcClientFileError to be returned in the monitor
1876 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1877 Affected file lib/silcclient/silcapi.h.
1879 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Fixed a crash in silc_client_ftp_free_sessions and
1882 silc_client_ftp_session_free_client. Affected file
1883 lib/silcclient/client_ftp.c.
1885 * Added `disabled' field in the SilcChannelEntry in the server
1886 to indicate if the server entry is disabled. Affected file
1887 silcd/idlist.h, silcd/command[_reply].c.
1889 * SILC server adds now /var/run/silcd.pid everytime it is
1890 started. Affected file silcd/silcd.c.
1892 * Added silc_server_packet_send_clients to send a packet to
1893 the provided table of client entries. Affected file
1894 silcd/packet_send.[ch].
1896 * Fixed a crash in client resolving in client_prvmsg.c in
1897 client library. Affected file lib/silcclient/client_prvmsg.c.
1899 * Do not actually remove the client directly from ID cache
1900 during SERVER_SIGNOFF, but invalidate it. This way we
1901 preserve the WHOWAS info for the client. Affected file
1902 silcd/server_util.c.
1904 * Fixed SERVER_SIGNOFF notify handling in the server. The
1905 server is now able to process incoming SERVER_SIGNOFF notify
1906 for a server that it doesn't even know about. It will remove
1907 the clients provided in the notify. Affected file
1908 silcd/packet_receive.c.
1910 * Check for partial packet in data queue after every packet that
1911 was found from the queue. Return and wait for more data if
1912 there is partial data in queue. Affected file is
1913 lib/silccore/silcpacket.c.
1915 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Added SilcClietFileError enum to indicate error in
1918 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1919 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1920 Affected files lib/silcclient/silcapi.h and
1921 lib/silcclient/client_ftp.c.
1923 * Check that newsize in silc_buffer_realloc is larger than
1924 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1926 * Added better monitor of file transfers. It now monitors
1927 key agreement protocol during the file transfer too. Added
1928 error reporting too. Affected files
1929 irssi/src/silc/core/silc-servers.c,
1930 irssi/src/fe-common/silc/module-formats.[ch].
1932 * Wrote a help file for FILE command.
1934 * Added silc_rng_global_get_byte_fast to get not-so-secure
1935 random data as fast as possible. Random data is read from
1936 /dev/urandom if available and from the SILC RNG if not
1937 available. It is used in padding generation. Affected file
1938 lib/silccrypt/silcrng.[ch].
1940 * All packets in client library are now processed synchronously.
1941 Optimized packet processing a lot. Affected file
1942 lib/silcclient/client.c.
1944 * All server connection packets are processing synchronously
1945 now in server, to optimize packet processing. Affected file
1948 * Include files are installed now only in Toolkit distribution
1949 if make install is given. Affected files: all Makefile.am's.
1951 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Assure that silc_client_notify_by_server_resolve does not
1954 resolve the client information multiple times. If it cannot
1955 be found by the first it cannot be found at all. Affected
1956 file lib/silcclient/client_notify.c.
1958 * Fixed WHOWAS command reply calling. Affected file
1959 lib/silcclient/command_reply.c.
1961 * Removed all references to silc_idlist_get_client from the
1962 Irssi SILC client since that call is internal call used by
1963 the library. The Irssi SILC client will use now client
1964 retrieval functions found in silcapi.h.
1966 * Fixed a bug in resolving nickname info before sending
1967 private message. It used freed memory. Affected file
1968 irssi/src/silc/core/silc-servers.c.
1970 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Assure my_channels statistics cannot go negative in server.
1973 Affected files silcd/server.c, silcd/server_util.c.
1975 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1979 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Win32 Toolkit changes. Affected files
1982 win32/silc.dsw, win32/libsilc/libsilc.def,
1983 win32/libsilcclient/libsilc.def,
1984 lib/silcutil/silcutil.c, and
1985 lib/sftp/sftp_fs_memory.c.
1987 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * Added silc_net_localip to return local host's IP address.
1990 Affected file lib/silcutil/silcnet.[ch].
1992 * If key exchange or rekey protocol is active for a connection
1993 parse all packets syncronously since there might be packets
1994 in packet queue that we are not able to process without first
1995 processing packets before them. Affected file silcd/server,
1996 lib/silcclient/client.c.
1998 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1999 whether library should continue processing the packet.
2000 Affected file lib/silccore/silcpacket.h.
2002 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2003 SilcSFTPMonitorData to SFTP server to monitor various
2004 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2005 lib/silcsftp/sftp_server.c.
2007 * Added silc_file_size to return file size. Affected file
2008 lib/silcutil/silcutil.[ch].
2010 * Implemented the file transfer support for the client library.
2011 Added preliminary support for simple client to client one-file
2012 transmission. Affected file lib/silcclient/client_ftp.c,
2013 lib/silccilent/client.[ch].
2015 * Added new local command FILE to the Irssi SILC Client.
2016 It is used to perform the file transfer. It has subcommands
2017 SEND, RECEIVE, SHOW and CLOSE. Affected files
2018 irssi/src/silc/core/client_ops.c,
2019 irssi/src/silc/core/silc-server.[ch].
2021 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * Relay the SILC_PACKET_FTP in the server. Affected files

2026 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Renamed silc_file_read and silc_file_write to functions
2029 silc_file_readfile and silc_file_writefile. Added function
2030 silc_file_open and silc_file_close. Affected files
2031 lib/silcutil/silcutil.[ch].
2033 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Resolve the client info when received private message or
2036 channel message for a client which nickname we don't know.
2037 Affected files lib/silcclient/client_prvmsg.c and
2038 lib/silcclient/client_channel.c.
2040 * Do not crash in /KEY if client is not connected. Affected
2041 file irssi/src/silc/core/silc-channels.c.
2043 * Added SilcClientStatus field to the SilcClientEntry in the
2044 lib/silcclient/idlist.h.
2046 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2047 is incomplete and is being resolved, it won't be resolved
2050 Make sure also that USERS command reply does not resolve
2051 twice information. Affected file is
2052 lib/silcclient/command_reply.c.
2054 Make sure that silc_client_get_clients_by_list does not
2055 resolve twice same information.
2057 * Check for valid client->id in the silc_server_free_client_data.
2058 Affected file silcd/server.c.
2060 * Fixed /GETKEY nick@server not to crash if the server entry
2061 is not found. Affected file lib/silcclient/command.c.
2063 * Fixed the silc_server_check_cmode_rights to check the
2064 requested modes correctly. Affected file silcd/command.c.
2066 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Better checks for non-printable chars in nick added.
2069 Affected file silcd/command.c.
2071 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * Call the silc_server_udpate_servers_by_server in the
2074 primary router that comes back online in the backup resuming
2075 protocol. Otherwise it routes packets wrong. Affected file
2076 silcd/server_util.[ch], silcd/server_backup.c.
2078 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2081 lib/silcutil/silcbuffmt.[ch].
2083 * Redefined the SILC packet header to include the padding
2084 length. Affected file lib/silccore/silcpacket.[ch].
2086 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2087 length for maximum padding up to 128 bytes). Affected
2088 file lib/silccore/silcpacket.h.
2090 * Removed all backwards support for old 0.5.x MAC thingies.
2091 The SILC packet header change makes it impossible to be
2092 backwards compatible.
2094 * Send the ENDING packet with timeout in the backup resuming
2095 protocol. This is to assure that all routers has connected
2096 to the primary router. Affected file silcd/server_backup.c.
2098 * Changed the RNG to take the first IV from random data. It
2099 used to take it from zero actually. Changed the RNG also
2100 to use /dev/urandom during session. /dev/random is used
2101 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2103 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Changed the SILC packet header to have the first two bytes
2106 (the packet length) encrypted. Affected files aroung the
2107 code tree, lib/silccore/silcpacket.[ch]. Removed the
2108 SilcPacketCheckDecrypt callback. It is not needed anymore
2109 since the silc_packet_receive_process will determine now
2110 whether the packet is normal or special.
2112 * Implemented the unidirectional MAC keys. Affected files
2113 lib/silcske/silcske.c, silcd/protocol.c and
2114 lib/silcclient/protocol.c.
2116 * Implemented the packet sequence number to the MAC computation.
2117 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2118 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2119 lib/silcclient/protocol.c.
2121 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Allow backup router to announce servers. All servers
2124 announced by backup router are added to the global list
2125 automatically. Update hte server's socket to our primary
2126 router also when backup router announces a server.
2127 Affected file silcd/packet_receive.c.
2129 * Do not update the client->router in the function
2130 silc_server_udpate_clients_by_server if the client is on
2131 global list. We might fail to find any specific server
2132 for locally connected clients and local cell clients. They
2133 should still use the `from' and not `to' as client->router.
2134 This fixes backup router resuming protocol. Affected file
2135 silcd/server_util.c.
2137 * Decrease channel statistics count only if the channel
2138 deletion worked. Affected files are silcd/server.c and
2139 silcd/server_util.c.
2141 * Added silc_server_update_servers_by_server to update origin
2142 of all server entries. Used during backup router protocol.
2143 Affected files silcd/server_util.[ch], silcd/server.c. and
2144 silcd/backup_router.c.
2146 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2147 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2148 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2149 lib/silccrypt/silchmac.c.
2151 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2153 * Assure that router cannot reroute the same channel message
2154 to the sender. Affected file silcd/packet_receive.c.
2156 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Made better checks that the channel message is not sent
2159 to the router it came from. Affected file is
2160 silcd/packet_send.c. Fixed memory leak too.
2162 * Announce informations for incoming router connection, but
2163 only after checking if it is replaced by backup router.
2164 Affected file silcd/packet_receive.c.
2166 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Fixed the backup resuming protocol to work in multiple
2169 router environment. Affected file silcd/server_backup.c.
2171 * Route packet only to one router in the function
2172 silc_server_packet_send_to_channel. Affected file is
2173 silcd/packet_send.c.
2175 * Fixed silc_server_send_notify_dest to set the broadcast
2176 flag. Fixed the silc_server_send_notify_topic to actually
2177 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2178 Affected file silcd/packet_send.c.
2180 * Changed the SFTP Filesystem interface. Changed the
2181 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2182 the filesystem operation function. The SilcSFTPFilesystem
2183 is now a context that is allocated by all filesystem allocation
2184 functions and it already includes the operations structure
2185 and filesystem specific context. It is given as argument
2186 now to the silc_sftp_server_start. This made the interface
2187 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2188 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2190 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Changed the backup router adding and getting interfaces
2193 in the server. The router that will be replaced by the
2194 specified backup router is now sent as argument. Affected
2195 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2198 * Added silc_net_addr2bin_ne to return the binary form of
2199 the IP address in network byte order. Affected files
2200 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2202 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Check for existing server ID in silc_server_new_server
2205 and in silc_server_connect_to_router_final and remove the
2206 old entry if it exists. Affected file silcd/packet_receive.c,
2209 * Send the channel message always to only one router, either
2210 in upstream or downstream. Affected file is
2211 silcd/packet_send.c.
2213 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Wrote the definition of the backup resuming protocol to the
2216 protocol specification.
2218 * Removed one redundant channel key generation from normal
2219 server during joining procedure. Removed one redundant
2220 channel key sending from server to router during joining
2221 procedure. Affected file silcd/command.c.
2223 * Made minor bugfixes to the backup router resuming protocol.
2224 Affected file silcd/server_backup.c, server.c.
2226 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Added --disable-asm configuration option. Affected files
2229 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2232 * Implemented the backup resuming protocol that is used to
2233 resume the primary router position in the cell after the
2234 primary router comes back online. Affected files
2235 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2236 and silcd/server_util.[ch].
2238 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Sleep two (2) seconds after sending QUIT command to server.
2241 Affected file lib/silcclient/command.c.
2243 * Assure that if outgoing data buffer is pending do not force
2244 send any data. Affected file silcd/packet_send.c.
2246 * Assure that if outgoing data buffer is pending do not force
2247 send any data. Affected file lib/silcclient/client.c.
2249 * Implemented the backup router support when the primary router
2250 goes down. The servers and routers can now use the backup
2251 router as new primary router without loosing connectivity.
2253 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2256 in the server to indicate disabled entry. All data read
2257 from the connection will be ignored and no data is sent
2258 for entry that is disabled. Affected files are
2259 silcd/idlist.h, silcd/server.c.
2261 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Created SFTP client and server test programs in the
2264 lib/silcsftp/tests directory.
2266 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Implemented memory filesystem (virtual filesystem) for
2269 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2272 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Implemented the SFTP (SSH File Transfer Protocol) to the
2275 lib/silcsftp. It includes SFTP client and SFTP server
2278 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Moved lib/silccore/silcprotocol.[ch] to the
2281 lib/silcutil library.
2283 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2284 take variable argument list pointer as argument. Affected
2285 file lib/silcutil/silcbuffmt.[ch].
2287 * Added silc_buffer_set function that is used to set data
2288 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2289 Affected file lib/silcutil/silcbuffer.h.
2291 * Changed various routines in the core library to use the new
2292 silc_buffer_set instead of allocating new buffer only for
2295 * Added 64-bit value formatting and unformatting support to the
2296 silc_buffer_[un]format routines. Affected file is
2297 lib/silcutil/silcbuffmt.[ch].
2299 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2300 to includes/bitmove.h.
2302 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * Fixed channel user mode saving in client library. Affected
2305 file lib/silcclient/command[_reply].c.
2307 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Defined the file transfer to the SILC Protocol. Added
2310 new packet type SILC_PACKET_FTP and defined File Transfer
2311 Payload. The mandatory file transfer protocol is SFTP
2312 (SSH File Transfer Protocol). Affected file in addition
2313 of the internet draft is lib/silccore/silcpacket.h.
2315 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2316 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2317 is used as part of backup router protocol when the primary
2318 router of the cell is back online and wishes to resume
2319 the position as primary router.
2321 * Redefined the MAC generation keys in the protocol. The
2322 same key is not used anymore in both direction. Both
2323 direction will now use different keys for sending and
2324 receiving. This fixes a potential security flaw. This
2325 change causes incompatibilities in the protocol.
2327 * Redefined also the MAC computation from the packet.
2328 An packet sequence number is now added to the MAC
2329 computation. This prevents possible replay attacks against
2330 the protocol. This change too causes incompatibilities
2333 Added `sequence' field to the SilcPacketContext to hold
2334 the current sequence number for the packet.
2336 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Added `created' field to the SilcIDListData in the file
2339 silcd/idlist.h to indicate the time when the entry was
2342 * Added `created' field to the SilcChannelEntry too. Affected
2343 file silcd/idlist.h.
2345 * Added `creation_time' aguments to all the announcement functions
2346 in the server. If it is provided then only the entries that
2347 was created after the provided time frame are actually
2348 announced. Affected file silcd/server.[ch].
2350 * The protocol says that the Channel ID's IP address must be
2351 based on the router's IP address. Added check for this in
2352 the silc_server_new_channel when processing incoming New Channel
2353 Payload. Affected file silcd/packet_receive.c.
2355 * Print out the correct version with --version in SILC client.
2356 Affected file irssi/src/silc/core/silc-core.c.
2358 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Fixed WHOWAS command to check for completnes of the client
2361 entry always, not just when the command is coming from client.
2362 Affected file silcd/command.c.
2364 * Added new function silc_server_packet_queue_purge to purge the
2365 outgoing data queue to the network. After the function returns
2366 it is guaranteed that the outgoing packet queue is empty.
2367 Affected file silcd/packet_send.[ch].
2369 * Purge the outgoing packet queue in the rekey protocol's final
2370 callback to assure that all rekey packets go to the network
2371 before quitting the protocol. Affected file silcd/server.c.
2373 * Added silc_client_packet_queue_parse as similar function as
2374 in server to the client library. The affected file is
2375 lib/silcclient/client.c.
2377 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Splitted silcd/server.c and created silcd/server_util.[ch]
2380 for utility functions.
2382 * Added new socket flag SILC_SF_DISABLED to indicate that the
2383 connection is open but nothing can be sent to or received from
2384 the connection. Affected file lib/silcutil/silsockconn.[ch].
2385 The checking for disabled socket is checked in the low level
2386 silc_socket_write and silc_socket_read functions.
2388 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Allow only nicknames and channel names that fits into the
2391 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2393 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * When processing JOIN command reply in server check that if
2396 the channel exists in our global list we'll move it the local
2397 list. Affected file silcd/command_reply.c.
2399 * Fixed the check whether client is joined on the channel already
2400 in JOIN command. Affected file lib/silcclient/command.c.
2402 * Fixed the JOIN command reply to check whether the channel
2403 already exists. Affected file lib/silcclient/command_reply.c.
2405 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Added silc_ske_status_string to map the SKE error numbers
2408 to readable strings. The affected files are
2409 lib/silcske/silcske[_status].[ch].
2411 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Do not show the private channels on the WHOIS channel list
2414 as it is not allowed by the protocol. The affected file is
2417 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Assure that the packet length digged from the actual packet
2420 is something sensible in the silc_packet_decrypt_rest_special
2421 in lib/silccrypt/silcpacket.c.
2423 * Free and NULL the allocated pointer in silc_hmac_alloc if
2424 the HMAC allocation fails. The affected file is
2425 lib/silccrypt/silchmac.c.
2427 * Print the selected security properties to the log files in
2428 the server. Affected file silcd/protocol.c.
2430 * Add SKE's reference counter even if calling the completion
2431 callback manually. Otherwise it goes negative, although it
2432 does not cause any problems. The affected file is
2433 lib/silcske/silcske.c.
2435 * Remove the client entry with short timeout after giving the
2436 KILL command. Affected file lib/silcclient/command.c.
2438 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2439 case all found clients are already disconnected (WHOWAS would
2440 found them) in the server. Affected file silcd/command.c.
2442 * Update the last_receive (time of last data received) to be
2443 updated only when received private or channel message so that
2444 the idle time showed in WHOIS makes more sense.
2446 * Added boolean field `valid' in to the SilcClientEntry in the
2447 client library to indicate whether the entry is valid or not.
2448 This fixes the nickname change bug on channel when changing
2449 the nickname to be same than the old (like nick to Nick) the
2450 nickname formatter doesn't set the new nick anymore to Nick@host.
2451 Affected file lib/silcclient/idlist.[ch].
2453 * Now actually fixed the nickname changing on disconnection.
2454 Added new function silc_change_nick to the Irssi SILC Client.
2455 Affected file irssi/src/silc/core/client_ops.c,
2456 irssi/src/silc/core/silc-nicklist.[ch].
2458 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Check that the public key exists in the GETKEY command before
2461 trying to encode it. Affected file silcd/command.c.
2463 * Print some notifications on received public keys with GETKEY
2464 command in the Irssi SILC Client. Affected files are
2465 irssi/src/fe-common/silc/module-formats.[ch],
2466 irssi/src/silc/core/client_ops.c.
2468 * Use IDENTIFY command to resolve the server information in the
2469 GETKEY command instead of INFO command. Affected file
2470 lib/silcclient/command.c.
2472 * All command reply functions in the client library now calls
2473 the pending command reply callbacks even if an error has
2474 occurred. The server has done this a long time and now it was
2475 time to move the client library to this as well. Now all
2476 errors can be delivered back to the pending command reply
2477 callbacks if necessary. Affected files are
2478 lib/silcclient/command[_reply].[ch].
2480 * Change the nickname on disconnection back to the username
2481 because in reconnect the server will enforce it to it anyway.
2482 Affected file irssi/src/silc/core/silc-servers.c.
2484 * Fixed a config file parsing bug in the Irssi SILC client.
2485 Affected file irssi/src/silc/core/clientconfig.c.
2487 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * When printing the channel mode on JOIN, verify that the
2490 channel key and channel's HMAC are valid. Affected file
2491 irssi/src/silc/core/client_ops.c.
2493 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2496 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2497 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2499 * Removed channel key rekey task deleting from the function
2500 silc_server_save_channel_key. Affected file silcd/server.c.
2501 Added explicit timeout task context instead that is used to
2502 delete the task if we are registering a new task before the
2503 new task has elapsed.
2505 * When channel key rekey occurs the client library now saves
2506 the old channel key for a short period of time (10 seconds) and
2507 is able to use it in case some is still sending channel
2508 messages encrypted with the old key after the rekey. Affected
2509 file lib/silcclient/[idlist.h|client_channel.c].
2511 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Added check to the silc_server_new_id_real to not accept
2514 new ID if it is the sender's own ID. Affected file is
2515 silcd/packet_receive.c.
2517 * Assure that we do not announce ourself or the one we've
2518 sending our announcements when we're router and are announcing
2519 servers to our primary router. Affected file silcd/server.c.
2521 * Fixed silc_server_command_identify_check_client to assemble
2522 correct WHOIS packet. It send corrupted WHOIS packet and
2523 caused problem with router to router connections. Affected
2524 file silcd/command.c.
2526 Fixed also silc_server_command_whois_check the same way
2527 as for the IDENTIFY command.
2529 * Added new SilcIDListStatus to the server in the SilcIDListData
2530 structure. The status now includes the current status of
2531 the entry (like registered, resolved etc.). Affected file
2532 silcd/idlist.[ch]. Defined a bunch of different status types
2533 as well. This replaced the old boolean registered field as well.
2535 Added resolve_cmd_ident field to the SilcClientEntry structure
2536 too so that if the entry is for example being resolved so
2537 another command may attach to the same pending command reply
2538 without requiring to resolve the same entry again. This concept
2539 should optimize the WHOIS and the IDENTIFY resolving under
2540 heavy load by taking away unnecessary resolving for entries
2541 that are being resolved already.
2543 Added support for adding multiple pending commands for one
2544 command idenfier. Affected file silcd/command[_reply].[ch].
2546 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2547 before deleting the data. Otherwise the hash table will have
2548 freed data in comparison functions. Affected file is
2549 silcd/command_reply.c.
2551 * Fixed silc_idlist_replace_client_id to add the new entry to
2552 the cache with NULL nickname. Otherwise there will be invalid
2553 memory as the nickname after the nickname is freed. Affected
2554 file silcd/packet_receive.c.
2556 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2557 saved into wrong slots because the previous number of entries
2558 was not taken into account. Affected file silcd/idlist.c.
2559 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2561 * If we are router and we receive JOIN notify to a channel that
2562 does not have any users then notified client is marked as the
2563 channel founder, as it is it. The affected file is
2564 silcd/packet_receive.c
2566 * Added to the extended hash table API's table_del_*ext functions
2567 the destructor as argument too, so that the caller can decide
2568 which destructor to use or whether to use destructor at all.
2569 Affected file lib/silcutil/silchashtable.[ch].
2571 * Fixed ID Cache purging. It actually deleted the entries from
2572 the hash table after the data was freed. The hash table ended
2573 up comparing freed memory. The affected file is
2574 lib/silccore/silcidcache.c.
2576 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Fixed Irssi SILC client's KILL command's HELP syntax.
2580 * The USERS command now resolves the detailed user information
2581 if the userinfo field is missing. Affected file is
2582 lib/silcclient/command_reply.c.
2584 * Do not print error in silc_file_read if the read file does
2585 not exist. Just silently return NULL. Affected file is
2586 lib/silcutil/silcutil.c.
2588 * Fixed the silc_log_output to not wine about NULL filename
2589 and to not create some bogus " " filename. Affected file is
2590 lib/silcutil/silclog.c.
2592 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Fixed various printing bugs on the user interface in the
2595 Irssi SILC Client. Minor changes that were forgotten from
2598 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Fixed the configure.in.pre and the compilation and distribution
2601 environment to support the new autoconf 2.52. That version is
2602 now required to compile the CVS trunk.
2604 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2607 to generally parse user@fqdn format strings. Affected file
2608 lib/silcutil/silcutil.c.
2610 * Added nickname_format and nickname_force_format fields to the
2611 SilcClientParams structure. The first one defines the format
2612 for the nicknames that the library will enforce if the receives
2613 multiple same nicknames. The second one is boolean value and
2614 can be used to force the library to always enforce the format
2615 to the nicknames regardles whether there are multiple nicknames
2616 or not. This configurable formatting was employed to flexibly
2617 support accessing multiple nicknames from the user interface.
2618 The userinterface can now set the nicknames to what ever format
2619 they prefer. Affected file lib/silcclient/silcapi.h.
2621 Added function silc_client_nickname_format to the file
2622 lib/silcclient/idlist.c. It performs the nickname formatting.
2624 Added new field `hostname´ to the SilcClientEntry context.
2625 It holds the hostname of the client. Affected file is
2626 lib/silcclient/idlist.h.
2628 * Irssi SILC Client sets the nicknames in nick@hostn format.
2629 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2630 irssi/src/silc/core/silc-core.c.
2632 The WHOIS printing now also shows both the real nickname and
2633 the formatted nickname so that user knows how to access the
2634 user if there are multiple same nicknames cached. Affected
2635 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2636 printing formatting too to take the hostname now as a separate
2637 argument. The Affected file is
2638 irssi/src/fe-common/silc/modules-formats.[ch].
2640 * Changed the silc_client_get_clients_local to accept the formatted
2641 nickname as argument. It accepts the real nickname too but the
2642 formatted nickname can be used to find the true entry from
2643 multiple entries. Affected file lib/silcclient/silcapi.h and
2644 lib/silcclient/idlist.c.
2646 * Added nickname_format_parse field to the SilcClientParams.
2647 It is a callback function provided by the application to parse
2648 the nickname out of the formatted nickname string. The library
2649 calls it to get the nickname from the formatted string. Since
2650 the application generally knows better the format of the nickname
2651 string it parses it instead of the library, even though library
2652 encodes the formatted string. If the callback function is not
2653 provided then the library will use the string as is. The
2654 affected file is lib/silcclient/silcapi.h.
2656 * All the nickname strings passed to the client library in
2657 commands are now expected to be formatted nickname strings.
2658 If the command does not support the formatted nickname string
2659 it will assume that the sent string is the actual nickname.
2660 Affected file lib/silcclient/command.c.
2662 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Added public key authentication support to OPER and SILCOPER
2665 commands in the client library. Affected file is
2666 lib/silcclient/command.c.
2668 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2670 * Changed the get_auth_methdod client operation to be asynchronous.
2671 It can be async if the application resolves the authentication
2672 method from the server during the negotiation. Added new
2673 SilcGetAuthMeth completion callback that the application will
2674 call after resolving the authentication method.
2676 Added function silc_client_request_authentication_method that
2677 the application can use to resolve the authentication method
2678 from the server. Added also SilcConnectionAuthRequest callback
2679 that the library will call after the server has replied. The
2680 application can call this function if it does not know the
2681 current authentication method.
2683 Affected files are lib/silcclient/client.c and
2684 lib/silcclient/silcapi.h.
2686 * The Irssi SILC client now automatically resolves the authentication
2687 method incase any configuration information is not present (and
2688 currently there never is). The affected file is
2689 irssi/src/silc/core/client_ops.c.
2691 * Fixed public key authentication from the client library.
2692 Affected file lib/silcclient/protocol.c. Changed also the
2693 protocol specification about the public key authentication in
2694 the connection authentication protocol. The actual data to be
2695 signed is now computed with a hash function before signing.
2697 * Fixed the public key authentication from the server as well.
2698 Affected file silcd/protocol.c.
2700 * Removed the mlock()'s from the memory allocation routines.
2701 Affected file lib/silcutil/silcmemory.c. The ./configure does
2702 not check anymore for the mlock(). Affected file is
2705 * Fixed USERS command in server to allow the execution of the
2706 command for private and secret channels if the client sending
2707 the command is on the channel. Affected file silcd/command.c.
2709 * Fixed silc_client_get_clients_local to return the clients
2710 count correctly. It could return wrong value. Affected file
2711 lib/silcclient/idlist.c.
2713 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2716 types. The assembler optimizations seemed not to like 64-bit
2717 data types. The assmebler optimizations thus are now enabled
2718 also for BSD systems as opposed to only enable them for Linux.
2720 * Do not check for threads at all on BSD systems. Affected
2721 file configure.in.pre.
2723 * Removed -n and -h options from the Irssi SILC Client since
2724 they are not used in silc.
2726 * Fixed the prime generation to assure that the first digit
2727 of the generated random number is not zero since our conversion
2728 routines does not like number strings that starts with zero
2729 digit. If zero digit is seen the random number is regenerated.
2730 This caused some corrupted RSA keys when the zero first digit
2731 was met. Affected file lib/silcmath/silcprimegen.c.
2733 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Fixed WIN32 configuration in the ./configure script.
2736 Fixed to include xti.h on environments that has it.
2737 Patches by Carsten Ilchmann and andrew.
2739 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Changed the silc_id_create_client_id to be collision
2742 resistant. It is now assured that there cannot be created
2743 two same client ID's. I suspect that some weird bugs in
2744 the server were actually caused by duplicate Client IDs.
2745 Affected file silcd/serverid.[ch]. A router receiving
2746 new ID now also assures and informs the sending server
2747 if the ID caused collision.
2749 * Changed the silc_id_create_channel_id to also assure that
2750 there are no collisions.
2752 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Statement about ignoring the Mutual Authentication flag when
2755 performing rekey with PFS was a bit misleading. It is ignored
2756 if it was set in the initial negotiation, it cannot be even
2757 set in the rekey. Fixed in the ke-auth draft. Started the
2758 new versions of the protocol drafts in the doc/.
2760 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2762 * Fixed a bug in silc_client_command_identify_save when saving
2763 new channel information. The channel name was no duplicated
2764 and caused crash on exit. Affected file is
2765 lib/silcclient/command_reply.c.
2767 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2769 * Fixed the getkey command handling in the server. Send just
2770 empty OK reply to the sender if the key could not be fetched
2771 (but everything else was ok, like the key just was not available).
2772 Changed the public key parameter to optional in the protocol
2773 specs so that empty OK reply can be sent. Affected file
2776 Added a message to Irssi SILC client to tell to user if the
2777 server did not return a public key.
2779 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Fixed a channel key regeneration bug. It registered new
2782 timeout tasks exponentially until all system resources were
2783 used. Affected file silcd/server.c.
2785 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Added the SILC Document generator to the scripts/silcdoc.
2788 It can be used to generate the Toolkit Reference Manual out
2789 of the source tree. Internally it will also use the RoboDoc
2790 generator now imported in util/robodoc.
2792 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Added couple of return's in rekey protocol if error orccurred
2795 during the protocol. The execution must be terminated.
2796 Affected file silcd/protocol.c. Also, terminate the protocol
2797 always with timeout.
2799 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * The client's Client ID was created initally from the wrong
2802 nickname (it could have been in format nick@host) in the
2803 silc_server_new_client. Affected file silcd/packet_receive.c
2805 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Added some SILC_LOG_ERROR's to various error conditions
2808 if client could not be added to ID cache. Affected files
2809 silcd/packet_receive.c and silcd/server.c.
2811 * When client's sock->user_data is freed, NULL also the
2812 client->router and client->connection pointers. Added check
2813 for these pointers being NULL to various places around the
2814 code. Affected file silcd/server.c.
2816 * Added client->data.registered == TRUE checks to various
2817 places around the code to assure that unregistered client's
2818 are not handled when it is not allowed. Affected file
2821 * Added `bool registered' fields to all
2822 silc_idlist_[server|client]_get_* routines to indicate whether
2823 the fetched client needs to be registered or not. Affected
2824 file silcd/idlist.[ch].
2826 * Add your own entry as registered to the ID cache in the
2827 server. Affected file server.c.
2829 * Fixed a bug in silc_server_new_server. The SilcServer was
2830 set as the new server's context instead of SilcServerEntry.
2831 This naturally caused some weird bugs.
2833 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Do not delete the channel rekey task when adding it
2836 for in silc_server_create_channel_key.
2838 * Changed the silc_server_create_channel_key to return
2839 TRUE or FALSE to indicate the success of the channel key
2842 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Fixed MSVC++ project files and added missing files to
2845 Makefiles under win32/.
2847 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2849 * Do not add TCP_NODELAY flag if the operating system
2850 does not have it defined. Affected files are
2851 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2853 * Fixed buffer overflow from Irssi SILC Client. Affected
2854 file irssi/src/fe-common/core/themes.c.
2856 * Fixed double free in client library in the file
2857 lib/silcclient/client.c when disconnecting from server.
2859 * Applied double free patch from cras to Irssi SILC client.
2860 Affected files irssi/src/core/[modules/expandos].c
2862 * Fixed the disconnection handling to Irssi SILC Client.
2863 The application must call silc_client_close_connection
2864 in ops->connect client operation in case of failure of
2865 the connection. Affected file is
2866 irssi/src/silc/core/client_ops.c.
2868 * Do not set sock->protocol to NULL in the function
2869 silc_client_close_connection after executing the protocol's
2870 final callback since the sock might not be valid anymore.
2871 Affected file lib/silcclient/client.c.
2873 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Do not enable SILC_THREADS if the linking with libpthread
2876 did not happen. Affected file configure.in.pre.
2878 * Added notion to protocol specification that server must
2879 verify the sent authentication payload with CMODE when
2880 setting the channel founder key. Implemented it to the
2881 server. Affected file silcd/command.c.
2883 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Added _EXTRA_DIST SILC distribution variable to the
2886 distributions file. It is used to conditionally add extra
2887 files or directories to the specific distribution. Affected
2888 files ./prepare, Makefile.am.pre and distributions.
2890 Removed the `_' from the start of the distribution names.
2893 * Added README.WIN32 for instructions to compile the Toolkit
2896 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Fixed a double free in disconnection in the server. Affected
2899 file is silcd/server.c.
2901 * Fixed the lib/silcske/groups.c to work now also with GMP
2902 MP library. The string conversion did not work when using
2903 specific base and the base is indicated in the string as well.
2905 * Created win32/ directory which now includes MSVC++ specific
2906 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2907 It will appear only in the toolkit distribution
2909 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Changed the key material distribution function in case when
2912 the hash output is too short. The data is now concatenated
2913 a bit differently than it used to. Made the change to the
2914 SKE protocol specification.
2916 * Added better GMP detection to configure.in.pre. A patch
2919 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Fixed a minor bug in SKE that might cause some problem on
2922 some platforms. Affected file lib/silcske/silcske.c.
2924 * Added the cookie checking for initiator in the SKE. It checks
2925 that the responder returns the sent cookie unmodified. The
2926 affected file is lib/silcske/silcske.c. Added new SKE
2927 error type INVALID_COOKIE that can be sent during the
2928 negotiation. Fixed some memory leaks as well.
2930 * Added the "invalid cookie" error message to Irssi SILC client's
2933 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Added `task_max' field to the SilcClientParams to indicate
2936 the maximum tasks the scheduler can handle. If set to zero,
2937 default values are used. Affected file lib/silcclient/silcapi.h.
2939 * Fixed memory leaks in silc_client_close_connection. Affected
2940 file lib/silcclient/client.c.
2942 * Added silc_client_del_client_entry to client library to free
2943 all memory of given client entry. Affected file is
2944 lib/silcclient/idlist.[ch].
2946 * Added new functions silc_client_del_channel and
2947 silc_client_del_server to delete channel and server entries.
2948 Affected file lib/silcclient/[silcapi.h/idlist.c].
2950 * Removed silc_client_del_client_by_id from silcapi.h.
2952 * Fixed the INFO command to return the server's own info
2953 correctly when querying by Server ID. Affected file is
2956 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Removed the non-blocking settings in WIN32 code in the
2959 silc_sock_[read/write] and added SleepEx instead. Affected
2960 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2961 of input data is now checked with FIONREAD and ioctlsocket.
2963 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Call silc_schedule_task_del_by_context in the
2966 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2967 Affected file lib/silccore/silcprotocol.c.
2969 * Call silc_protocol_cancel for active protocols in the
2970 silc_server_close_connection if the funtion
2971 silc_server_free_sock_user_data has not been called.
2972 Affected file silcd/server.c.
2974 * Generic tasks cannot be deleted using the del_by_fd
2975 task deleting function since generic tasks does not match
2976 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2978 * Added a notion to SILCOPER help file that the SILCOPER works
2979 only on router server, not on normal server.
2981 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Added for WIN32 support for the new scheduler as well.
2984 Affected file lib/silcutil/win32/silcwin32schedule.c.
2986 * Fixed the SHA1 implementation to work on various platforms.
2988 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2991 API. It is part of the scheduler now. Everything else is
2992 as previously but some functions has changed their names.
2993 Checkout the lib/silcutil/silcschedule.h for the interface.
2994 Updated all applications to use the new interface. Affected
2995 files are lib/silcutil/silcschedule.[ch].
2997 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Found a bug in the SKE implementation. The HASH value,
3000 specified by the protocol, was not computed correctly. The
3001 public key of the responder was not added to the computation
3002 even though it is mandatory. Affected file lib/silcske/silcske.c.
3003 This unfortunately causes incompatibilities with older
3004 clients and servers.
3006 * Added WIN32 specific network init and uninit functions:
3007 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3008 the Winsock2. Affected file lib/silcutil/silcnet.h and
3009 lib/silcutil/win32/silcwin32net.c.
3011 * Set the socket always to nonblocking mode on WIN32 after
3012 reading data or writing data. Affected file is
3013 lib/silcutil/win32/silcwin32sockconn.c.
3015 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Fixed various compilation problems under WIN32. Affected
3018 files lib/silcutil/win32/silcwin32thread.c and
3019 lib/silcutil/win32/silcwin32schedule.c.
3021 * Removed all _internal.h #includes from public header
3022 files. Internal headers must never be included from
3025 Removed also the lib/silcske/payload_internal.h file.
3027 * All include files that may be needed (public and some others
3028 included by the public headers) by application developers are
3029 now copied to the ./includes directory. It does not copy any
3030 internal headers. Affected file Makefile.defines.pre and all
3031 Makefile.am's under lib/ and subdirs.
3033 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Do not change the ~/.silc directory's permissions automatically.
3036 Affected file irssi/src/silc/core/clientutil.c.
3038 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Do not cancel the protocol in silc_server_close_connection
3041 it might cause recursion. Now cancelled in the function
3042 silc_server_free_sock_user_data. Affected file silcd/server.c.
3044 * Fixed the silc_server_remove_clients_by_server to regenerate
3045 the channel keys correctly finally. Added also new function
3046 silc_server_remove_clients_channels to actually do it.
3047 Affected file silcd/server.c.
3049 * Fixed the silc_server_new_channel to not crash by giving
3050 wrong router to the new channel. Affected file is
3051 silcd/packet_receive.c.
3053 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3056 which is given as argument to the silc_client_alloc now.
3057 It can be used to configure the client and set various parameters
3058 that affect the function of the client.
3060 * The USERS command in server did not check whether the channel
3061 is private or secret. Affected file silcd/command.c.
3063 * Added new argument to the USERS command in protocol specification.
3064 The USERS command now can take the channel name as argument
3065 as well. Added support for this in client and server and
3066 updated the protocol specs.
3068 * Completed the GETKEY command in client. It can be now used
3069 to fetch also servers public key not only some clients.
3070 Affected files lib/silcclient/command[_reply].c.
3072 * Added silc_client_get_server to return server entry by the
3073 server name. Affected files lib/silcclient/silcapi.h and
3076 * Redefined the IDENTIFY command in protocol specification to be
3077 more generic. It now can be used to query information about
3078 any entity in the SILC Network, including clients, servers and
3079 channels. The query may be based either the entity's name
3080 or the ID. Added support for this in both client and server.
3082 Affected files silcd/command.c and lib/silcclient/command.c
3083 and command_reply.c.
3085 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3086 the _from_client and _from_server functions. Affected file
3089 * Added silc_client_get_channel_by_id_resolve to the file
3090 lib/silcclient/silcapi.h to resolve channel information by
3091 its ID. Added also silc_client_get_channel_by_id that
3092 does not resolve it from the server.
3094 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3096 * Added SilcServerEntry context into the client library
3097 to represent one server. The INFO command now allocates
3098 these to save the resolved server info. For now on the
3099 client library will also keep information about servers,
3100 connected and resolved with INFO.
3102 The INFO command now allocates the SilcServerEntry context
3103 and saves the server info there. The COMMAND_REPLY in
3104 the INFO now returns the parameters to application in
3105 same order as defined in the protocol specification.
3107 The entries are cached in the client->server_cache.
3109 * The INFO command is now issued after received the Client ID
3110 from the server. Affected file lib/silcclient/client.c.
3112 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3113 to the application as the mode changer might be server.
3114 It is guaranteed that NULL is not returned anymore to the
3115 application. Affected file lib/silcclient/client_notify.c.
3117 The ID Type is now also passed to the application so that
3118 it can check whether the returned entry is SilcClientEntry
3121 Added new function silc_client_get_server_by_id to return
3122 the server entry by ID. Affected files are the
3123 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3125 * Do not create the channel in the Irssi SILC Client when issuing
3126 the JOIN command but when received the sucessful JOIN command
3127 reply. Otherwise the channel might get created even though we
3128 could not join it. The Affected file is
3129 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3131 * Fixed a channel joining bug in router. The router must also
3132 check the channel modes, invite and ban lists etc. when serving
3133 the JOIN command sent by normal server. Affected file is
3134 silcd/command.c. The router now resolves the client's
3135 information from the server who sent the JOIN command if it
3136 does not know it, and processes the JOIN command only after
3139 * Changed the SilcCommandCb to take new argument; void *context2.
3140 Affected file lib/silccore/silccommand.h
3142 The second argument in the command callbacks in the server now
3143 includes the SilcServerCommandReplyContext if the command was
3144 called as pending command callback from the command reply.
3145 Otherwise it is NULL. When called as pending the status of the
3146 command reply will be checked and if it was erronous the
3147 error will be sent to the original sender of the command.
3148 This way the client always receives the error messages even
3149 though the server was actually the one who received the error
3150 when it resent the command to router, for example. Affected
3151 files silcd/command[_reply].[ch].
3153 * Fixed sending WHOWAS command's error message to client if
3154 the requested client could not be found. It was missing.
3157 * Changed the CMODE and CUMODE commands reply arguments in the
3158 protocol specification. The Channel ID is now sent in both
3159 of the commands to identify the channel. Implemented this
3160 new feature to the client and server. Affected files
3161 lib/silcclient/command_reply.c and silcd/command.c.
3163 * Made better checks for invite and ban lists in the JOIN
3164 command in server. Affected file silcd/command.c.
3166 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3168 * The server now performs the incoming host IP/DNS lookup
3169 using the silc_socket_host_lookup and thus does not block
3170 the server anymore. Affected file silcd/server.c.
3172 * Completed the multi-thread support for SILC Scheduler in
3173 the lib/silcutil/silcschedule.c.
3175 * Fixed the configure.in.pre to detect the pthread correctly
3178 * Fixed a deadlock in silc_task_queue_wakeup in the file
3179 lib/silcutil/silctask.c.
3181 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3183 * Added new function silc_schedule_wakeup that is used in
3184 multi-threaded environment to wakeup the main thread's
3185 schduler. It needs to be used when a thread adds a new task
3186 or removes a task from task queues. After waking up, the
3187 scheduler will detect the task queue changes. If threads
3188 support is not compiled in this function has no effect.
3189 Implemented the wakeup mechanism to both Unix and WIN32
3190 systems. Affected files are lib/silcutil/silcschedule.[ch],
3191 lib/silcutil/unix/silcunixschedule.c and the
3192 lib/silcutil/win32/silcwin32schedule.c.
3194 * Added new function silc_task_queue_wakeup to wakeup the
3195 scheduler by the specified task queue. Affected file
3196 lib/silcutil/silctask.[ch].
3198 * The silc_socket_host_lookup_start now wakes up the scheduler
3199 after adding the timeout task. Affected file is
3200 lib/silcutil/silcsockconn.c.
3202 * The silc_socket_host_lookup is synchronous now if the threads
3203 support is not compiled in. However, the callback is still
3204 called asyncronously through the scheduler, anyway. Affected
3205 file lib/silcutil/silcsockconn.c.
3207 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Added new function silc_socket_host_lookup to perform
3210 asynchronous IP and FQDN lookups for the socket connection.
3211 Affected files lib/silcutil/silcsockconn.[ch].
3213 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3215 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3216 that may or may not compile the mutex support in.
3218 Changed the silc_mutex_alloc interface. It allocates the
3219 mutex now to the sent pointer and returns TRUE or FALSE.
3221 Affected file lib/silcutil/silcmutex.h.
3223 * Wrote the SILC Task Queue interface to support multi-threads.
3224 Affected file lib/silcutil/silctask.[ch].
3226 * Wrote the SILC Scheduler to support multi-threads. Affected
3227 file lib/silcutil/silcschedule.c.
3229 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3232 in lib/silcutil/win32/.
3234 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Defined SILC Mutex API and SILC Thread API and implemented
3237 them for Unix. Affected files are
3238 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3239 lib/silcutil/unix/silcunixmutex.c and
3240 lib/silcutil/unix/silcunixthread.c.
3242 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3244 * Fixed the silc_server_remove_clients_by_server's channel
3245 key re-generation. The hash table handling was incorrect
3246 and would not work with many channels. Affected file is
3249 * Fixed some memory leaks around the server code.
3251 * Rewrote the silc_server_get_users_on_channel to support IPv6
3252 based Client ID's. Affected file silcd/server.c.
3254 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3255 specification. However, a separate document must be written
3256 to define the detailed signing procedure and the payload
3257 associated with the flag. Defined the flag to the
3258 lib/silccore/silcchannel.h as well.
3260 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Changed the dynamic tables to static size tables in the
3263 lib/silccrypt/silchmac.c.
3265 * Removed GCC dependencies from the code. A patch by cras.
3267 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Do not show the error "Error receiving packet bla bla"
3270 in server if it really was not an error (-2 means that reading
3271 is pending). Affected file silcd/server.c.
3273 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3275 * Fixed a possible crash in silc_server_remove_clients_by_server
3276 in silcd/server.c. Fixed there also some memory leaks.
3278 * Fixed the silc_idlist_replace_client_id. It could replace
3279 wrong key in the hash table. Affected file silcd/idlist.c.
3281 * Do not check whether there are global users on the channel
3282 if the channel->global_users is FALSE. Affected functions
3283 silc_server_remove_from_one_channel and
3284 silc_server_remove_from_channels in silcd/server.c. Also,
3285 do not check if the removed client is local as we can be
3286 sure that global client was not removed from the channel
3287 and checking for global users is not needed.
3289 * The silc_server_remove_clients_by_server now re-generates
3290 the channel keys correctly for those channels that had
3291 clients removed from them. Affected file silcd/server.c.
3293 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3295 * Found the reason of random crashes in the server. We weren't
3296 ignoring the SIGPIPE signal (which can be sent in write())
3297 and it crashed the server. Affected file silcd/silcd.c.
3299 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Assure that sock->user_data is not NULL in the function
3302 silc_server_packet_send in silcd/packet_send.c.
3304 * Disconnect the remote connection if it could not be added
3305 to any ID lists in the server. The affected file is
3308 * Check in silc_server_packet_send[_real/dest] that the
3309 socket is not disconnecting and ignore the data if it is.
3310 Affected file silcd/packet_send.c.
3312 * Define inline to __inline on native WIN32 compilation.
3313 Affected file includes/silcwin32.h.
3315 * Added some explicit type casts for inline code since MSVC
3316 require them. Affected files lib/silcutil/silcbuffer.h,
3317 lib/trq/silcdlist.h and lib/trq/silclist.h.
3319 * Print warning in log files from now on if the packet
3320 decryption fails. Affected file silcd/server.c.
3322 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3324 * Changed the `say' client operation's interface to accept
3325 new `type' argument to indicate the type of the message sent
3326 by the library. The application may filter the library's
3327 messages according the type. The affected file is the
3328 lib/silcclient/silcapi.h.
3330 * Added two new functions to lib/silcclient/silcapi.h:
3331 silc_client_del_client and silc_client_del_client_by_id.
3332 Affected file lib/silcclient/idlist.c.
3334 * Moved the clientincludes.h from includes/ to silc/ and
3335 serverincludes.h from includes/ to silcd/.
3337 * The modes for the CMODE and CUMODE are now passed as
3338 uint32 for application with COMMAND_REPLY. The affected
3339 file is lib/silcclient/command_reply.c.
3341 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * /WHOIS without arguments shows client's own information.
3344 Affected file lib/silcclient/command.c.
3346 * Changed PING to not accept any arguments. The specs
3347 says that client can ping only the connected server so
3348 requiring an argument is not needed. Affected file is
3349 lib/silcclient/command.c.
3351 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3353 * Fixed a fatal bug in private message sending and reception
3354 encryption and decryption when using private message keys.
3355 The implementation was incorrect and did not follow the
3356 specification. It causd that some of the message were
3357 lost since it did not use the sending and receiving keys
3358 as the protocol suggests. This has been fixed and will cause
3359 incompatibilities with older clients when sending private
3360 message encrypted with private message keys. Affected files
3361 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3362 and various other in Irssi SILC Client.
3364 Added `responder' boolean argument to the functions
3365 silc_client_add_private_message_key[_ske] to indicate when
3366 the key is added as responder or initiator of the key
3369 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3371 * Removed the silc_ske_check_version function and created
3372 a SilcSKECheckVersion callback. Added also a function
3373 silc_ske_set_callbacks that is now used to set all SKE
3374 callbacks. The callback functions are not given to
3375 the SKE functions anymore, but this function is used to
3378 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3380 * Added `silc_version' argument to the silc_client_alloc
3381 to define the version of the application for the library.
3382 The library will use the version string to compare it
3383 against the remote host's (usually a server) version
3384 string. Affected file lib/silcclient/silcapi.h
3386 * Added the KE protocol context to Key Agreement context
3387 in client library so that we can abort the SKE if it
3388 is in process when we get timeout. Affected file is
3389 lib/silcclient/client_keyagr.c.
3391 * Do not resolve the client ID forever if it returns in the
3392 first time that such client does not exist. This was done
3393 for example with private message. Affected file is
3394 lib/silcclient/client_prvmsg.c.
3396 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3398 * Do not add regex.h for WIN32. The affected file
3399 includes/silcincludes.h.
3401 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3402 not work yet 100%. It generates the DLL's automatically
3403 when compiling with --with-win32 under cygwin.
3405 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * lib/contrib/regex.c is not compiled on WIN32.
3409 * Added silc_net_get_socket_opt function to the
3410 lib/silcutil/silcnet.h.
3412 * Added includes/silcwin32.h for WIN32 specific includes
3415 * Do not use ptime structure or any of the posix process
3416 functions on WIN32 in lib/silccrypt/silrng.c.
3418 * Added silc_gettimeofday to provide generic function
3419 for struct timeval on all platforms. Added the function
3420 to lib/silcutil/silcutil.h.
3422 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3425 library as they clearly belong there. As a plus side we
3426 can make the actual socket connection routines platform
3429 Added also new generic function silc_socket_read and
3430 silc_socket_write (that used to be silc_packet_[read/write].
3431 The implementation of these are platform specific.
3433 * Added WIN32 specific routines of silc_socket_[read/write]
3434 to lib/silcutil/win32/silcwin32sockconn.c.
3436 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Added preliminary support for native WIN32 compilation under
3439 cygwin (using the -mno-cygwin option for GCC) to the
3440 ./configure.in.pre. The --with-win32 now prepares the
3441 compilation for native WIN32.
3443 * Rewrote the SILC Scheduler interface in the file
3444 lib/silcutil/silcschedule.h. The scheduler is now context
3445 based and does not have anymore any global static scheduler.
3446 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3447 and created lib/silcutil/win32 directory for WIN32 based
3450 * Added Unix specific network routines to the
3451 lib/silcutil/unix/silcunixnet.c and the old
3452 lib/silcutil/silcnet.c includes now only generic routines.
3454 Added WIN32 specific network routines to the
3455 lib/silcutil/win32/silcwin32net.c.
3457 * Added Unix specific utility functions from the
3458 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3460 * Added WIN32 SILC Scheduler to the file
3461 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3464 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Do not handle JOIN notify in the server if the target client
3467 is not registered (idata->registered == FALSE). The affected
3468 file is silcd/packet_receive.c.
3470 * Update the nickrec->founder in event_cumode in the Irssi SILC
3471 client. Affected file irssi/src/silc/core/silc-channels.c.
3473 * Fixed the CUMODE_CHANGE notify handling in the server when
3474 server and router are announcing their clients on channels.
3475 Now the mode changes are saved and notified correctly. The
3476 affected file is /silcd/packet_receive.c.
3478 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3479 They really did not replace the cache entry in the ID Cache.
3480 Now they do that. Affected file silcd/idlist.c.
3482 * Fixed the KICK notify handling in the Irssi SILC client to
3483 update the channel records so that the kicked client does not
3484 appear to be on the channel. The affected file is
3485 irssi/src/silc/core/silc-channels.c.
3487 * Always update the conn->current_channel when executing command
3488 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3490 * Fixed the KILL notify handling in Irssi SILC client to remove
3491 the killed client on all channels.
3493 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Fixed the silc_parse_command_line to remove extra spaces
3496 from the start and end of the arguments. Affected file is
3497 lib/silcutil/silcutil.c.
3499 * Cancel and free any active protocol in the function
3500 silc_server_close_connection. Affected file silcd/server.c.
3502 * Cancel and free any active protocol in the function
3503 silc_client_close_connction. Affected file is
3504 lib/silcclient/client.c.
3506 * Do not execute the KILL command for clients that are in
3507 history (ie. they are not in the network). Affected file is
3510 * Fixed KILL notify handling, client does not crash anymore.
3511 Affected file irssi/src/silc/core/silc-channels.c.
3513 * Reduced the default packet buffer size from 2048 to 1024 in
3514 lib/silccore/silcpacket.c.
3516 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3517 counter to the SKE context that is incresed when the SKE library
3518 performs async operation outside the library. If the outside
3519 process frees the SKE context and FREED status will be set
3520 and the library will detect after the sync operation that the
3521 libary is freed. The affected files are
3522 lib/silcske/silcske[_status].[ch].
3524 * Resolve the client entry information in the function
3525 silc_client_channel_message to assure that NULL pointer is not
3526 passed as client entry to the application. */
3528 * Fixed the task timeout calculation to assure that there is
3529 never negative timeouts. The affected file is
3530 lib/silcutil/silcschedule.c.
3532 * Fixed the channel user mode notification sending in server.
3533 It was sent point-to-point to the router (or to server by router)
3534 but it needs to be destined to a channel. The routines now
3535 supports sending the channel user mode notifys to the channels
3536 when announcing clients and channels. Affected files are
3537 silcd/server.c and silcd/packet_receive.c.
3539 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3540 It did not actually replace the old channel entry in the cache.
3541 Affected file lib/silcclient/client_notify.c.
3543 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Fixed a possible crash in silc_packet_send_prepare. It now
3546 assures always that there is enough space in the buffer and
3547 at the tail area of the buffer (for MAC).
3549 Fixed the inbound buffer reallocation in silc_packet_read.
3550 It was old code and did not handle the reallocation correctly.
3553 The affected file is lib/silccore/silcpacket.c.
3555 * Fixed buffer overflow in silc_parse_nickname in the file
3556 lib/silcutil/silcutil.c.
3558 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * make install generates new server keys only if there is not
3563 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3566 Added check that if the NOREPLY is set then we will not send
3567 the away message. This avoids infinite loop of away messages
3568 if both clients are away. The affected file is
3569 lib/silcclient/client_prvmsg.c.
3571 * Fixed client crash if /NICK was given without arguments.
3572 Affected file lib/silcclient/command.c.
3574 * Server does not send the invite list in INVITE command back
3575 to the client if the list was not altered. Added this notion
3576 to the protocol spec as well. Affected file silcd/command.c.
3578 Fixed possible crash in INVITE command by checking the
3579 value of silc_server_get_client_route command.
3581 * Fixed the INVITE notify type handling. The arguments are now
3582 taken in correct order and client does not crash. The affected
3583 file is irssi/src/silc/core/silc-channels.c.
3585 Removed the "Inviting xxx to channel" message from the
3586 client library away and let the application handle it.
3587 Affected file lib/silcclient/command.c. Added that message
3588 to Irssi SILC client's message formats.
3590 * Fixed CMODE command crash in client. It now checks the
3591 amount of arguments correctly and does not crash. The affected
3592 file is lib/silcclient/command.c.
3594 * Do not create new channel automatically in silc_channels_join
3595 but check whether the channel by that name already exists.
3596 Affected file irssi/silc/core/silc-channels.c.
3598 * Do not send the SERVER_SIGNOFF to router if the disconnected
3599 entity was the router. Affected file silcd/server.c.
3601 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3602 SILC client as it was missing from there.
3604 Added the handling of the KICK notify to the Irssi SILC client
3605 as it was missing. Added "you have been kicked" message to
3606 Irssi SILC client's message modules formats.
3608 Added the handing of the KILL notify to the Irssi SILC client
3609 as it was missing. Added the kill message module formats
3612 The affected file is irssi/src/silc/core/silc-channels.c.
3614 * The router did not save the channel mode the server announced.
3615 Affected file silcd/packet_receive.c.
3617 * Fixed a possible crash in INFO command in server. If the
3618 server did not provide the server info it crashed. Affected
3619 file silcd/command.c.
3621 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Fixed the GETKEY command in the server to check also the
3624 global list. Otherwise the GETKEY would not work correctly
3625 in normal SILC server. Affected file silcd/command.c.
3627 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Fixed GETKEY crash, it crashed if the command did not succseed.
3631 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3634 is now real and not just an macro interface to GMP.
3636 Removed the entire GMP from the source tree and imported new
3637 NSS MPI library instead. Reason for removing GMP is that it is
3638 extremely large and compiles extremely slow. The NSS MPI
3639 is only a few files and compiles in less than 10 seconds.
3640 The speed is also about the same as GMP. The MPI is imported
3641 to lib/silcmath/mpi.
3643 If the system has GMP installed we will still use the GMP.
3644 If it is not then the NSS MPI will be compiled.
3646 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Merged a long nickname (127 characters long) crash bugfix from
3649 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3651 * Merged a freed memory reference bugfix from Irssi CVS tree.
3652 Affected file irssi/src/core/commands.c.
3654 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Added the server's public key sving and verification to the
3657 server when performing the SKE. This was missing and the
3658 remote server's (or router's) public key was accepted without
3659 checking whether we have it previously or trust it at all.
3660 Affected file silcd/protocol.c.
3662 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Check in the silc_server_timeout_remote if protocol is active
3665 and make sure that the protocol's final callback is called so
3666 that all memory if freed. Affected file silcd/server.c.
3668 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * silc_server_whois_send_reply crashed the server if the nickname
3671 was 127 characters long. Affected file silcd/command.c.
3673 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Added sanity check to the silc_server_new_client. If the hostname
3676 is provided inside username then check that the provided hostname
3677 really is the same as the resolved one. If the hostname was not
3678 resolved then check it from the public key. Affected file is
3679 silcd/packet_receive.c.
3681 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3682 if the server disconnected us and the connection is not valid
3683 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3685 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3686 the library to the lib/silcutil/silcutil.[ch].
3688 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * Close log file after open. Affected file
3691 lib/silcutil/silclog.c.
3693 * Check whether sock == NULL in silc_client_send_packet and return
3694 if it is. Affected file lib/silcclient/silcclient.c.
3696 * Check rec->entry == NULL in the Irssi SILC Client before
3697 sending the channel message. Affecte file is
3698 irssi/src/silc/core/silc-servers.c.
3700 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Merged a splitted window bugfix from Irssi CVS tree. The
3703 affected file is irssi/src/fe-text/textbuffer-view.c.
3705 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3706 It did not print nickname.
3708 * Improved the distributions system a bit.
3710 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3713 irssi/src/fe-text/gui-window.c.
3715 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3716 to in-active server. The affected file is
3717 irssi/src/silc/core/client_ops.c.
3719 * Resolve the client in USERS command reply if the entry does
3720 not have username resolved. The affected file is
3721 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3722 command to WHOIS command to really resolve stuff. The USERS
3723 is not used any more in any critical section so WHOIS can
3724 be used even though it might be slower than IDENTIFY.
3726 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3729 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Changed the protocol API a bit more consistent in the
3732 lib/silccore/silcprotocol.[ch].
3734 * Changed the following headers to ROBODoc format:
3736 lib/silccore/silcpayload.h
3737 lib/silccore/silcprotocol.h
3738 lib/silccore/silcsockconn.h
3740 All core library headers are now formatted.
3742 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Fixed a bug in Irssi SILC client; do not show that you are
3745 server/router operator if you really are not. Affected file is
3746 irssi/src/silc/core/client_ops.c.
3748 * Renamed silc_command_free_payload to silc_command_payload_free.
3749 Affected file lib/silccore/silccommand.h
3751 * Added silcmath.h to include the prototoypes of various routines
3752 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3755 * Changed the following headers to ROBODoc format:
3757 lib/silccore/silcchannel.h
3758 lib/silccore/silccommand.h
3759 lib/silccore/silcid.h
3760 lib/silccore/silcidcache.h
3761 lib/silccore/silcmode.h
3762 lib/silccore/silcnotify.h
3763 lib/silccore/silcpacket.h
3764 lib/silcmath/silcmath.h
3766 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Added checking to the server code not to start the server if
3769 ciphers and stuff are not configured properly. Affected files
3770 silcd/serverconfig.[h] and silcd/server.c.
3772 * Changed the layout of the header files of the public interfaces
3773 in the SILC libraries. The new layout supports ROBODoc
3774 documentation tool (and some others) so that it is easy to create
3775 a library reference manual. All the other headers and source
3776 code must still follow the CodingStyle document. Also source
3777 code must not include these ROBODoc stuffs, only the headers.
3778 Furthermore, all public interface headers must now be named
3779 by using `silc' prefix, example: silcapi.h, silccipher.h.
3780 Some files were renamed due to this. All the other headers
3781 must not be used as public interfaces. I will update the
3782 CodingStyle document later. Changed following headers, so far:
3784 lib/silcclient/silcapi.h
3785 lib/silccore/silcauth.h
3786 lib/silccore/silcprivate.h
3787 lib/silccrypt/silcdh.h
3789 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Removed silc_client_packet_send_flush from the client library
3794 as it is not needed. Affected file lib/silcclient/client.[ch].
3796 * Added printing of message of unresolved authentication method
3797 to the Irssi SILC client. Added it to the module formats.
3798 Removed the same message from the client library.
3800 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Added new distribution feature, DISTLABEL. Every distribution
3803 can define own preprocessor label that can be used in the
3804 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3805 file distributions, acconfig.h.pre and prepare.
3807 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Added Makefile.defines_int to include the actual definitions
3810 for Makefile.defines.in. Tested the new distribution system,
3811 created distributions and tested installation.
3813 * Added AWAY message printing to the Irssi SILC client. Added
3814 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3816 * Added SCONNECT command to call the SILC's CONNECT command.
3817 Cannot use CONNECT directly since Irssi uses that internally.
3818 Affected file irssi/src/silc/core/silc-servers.c.
3820 Added ACTION local command. It is same as ME command but takes
3821 the channel as mandatory argument.
3823 Rewrote some of the Irssi's help files to suite for SILC
3826 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Added Makefile.defines[.in] that should for now on be included
3829 in all Makefile.am file in the source tree. That file includes
3830 all common compilation definitions for SILC source tree.
3832 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Minor changes to the ./prepare script to change the package
3835 name according the distribution name to the configure.in.
3837 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Created new distribution system. Added file `distributions'
3840 that defines all the distributions that can be created out of
3841 the SILC source tree. The ./prepare script now reads that
3842 file to determine how to prepare the distributions. The
3843 first argument to the ./prepare is the name of the distribution
3844 and second is the version of the distribution. If given
3845 without arguments it creates the default (toolkit) distribution
3846 with the default version (defined in ./prepare).
3848 All Makefile.am files that are subject to the distributions
3849 are now named as Makefile.am.pre. These are ./Makefile.am
3850 and lib/Makefile.am. Others may be changed later.
3852 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Added invite list, ban list, some key management and connection
3855 error message printing to module formats in the Irssi SILC client.
3857 * Added new silc_client_set_away_message to set the away message
3858 that is back to the person who sent private message. The
3859 affected file lib/silcclient/silcapi.h and the
3860 lib/silcclient/client_prvmsg.c.
3862 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Fixed the private message sending in the Irssi SILC client,
3865 added local command KEY to the Irssi SILC client.
3867 Added key management and key agreement message formats to the
3868 irssi/src/fe-common/silc/module-formats.[ch].
3870 Added USERS (alias WHO) printing, server/router operator
3871 indication and LIST command printing to the module formats.
3873 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Fixed channel joining notify handling, cumode notify handling
3876 from Irssi SILC client.
3878 * Added SILC specific module-formats to the Irssi SILC client so
3879 that SILC specific message hilighting, colors etc is possible.
3880 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3882 Added channel mode, channel user mode, actions, notices,
3883 whois and whowas printing to the the module-formats.c.
3885 * Fixed a bug in channel deletion in the server. The channel
3886 is not left to the cache even if the channel founder auth mode
3887 is set when there are no users anymore on the channel. Affected
3888 file silcd/server.c.
3890 * The silc_net_localhost now resolves the entire hostname including
3891 the domain name. Affected file lib/silcutil/silcnet.c.
3893 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Changed the ask_passphrase client operation to be ascynchronous.
3896 It has now a completion callback and a context that the
3897 application must call after it has got the passphrase from
3898 the user. Affected files lib/silcclient/silcapi.h,
3899 lib/silcclient/protocol.c, lib/silcclient/command.c and
3902 Added SilcAskPassphrase callback that the application calls
3903 to deliver the passphrase to the library.
3905 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3906 The public key verification and especially a certificate
3907 verification is asynchronous procedure.
3909 Added new SILC_SKE_STATUS_PENDING status to indicate the
3910 request is pending and a callback will be called to finalize
3913 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3914 indicate that remote end did not send its public key (or
3915 certificate), even though we require it. Added check for this
3916 condition in the SKE. This was a security bug, now fixed.
3918 Defined new SilcSKEVerifyCbCompletion callback that is called
3919 when the verification process is completed.
3921 The affected files lib/silcske/silcske_status.h and
3922 lib/silcske/silcske.[ch].
3924 * Changed the verify_public_key client operation to be async
3925 as well. Defined SilcVerifyPublicKey callback that is used to
3926 indicate the success of the public key verification process.
3928 Changed the server and client to use the new async client
3931 * Changed the Irssi SILC client's internal scheduler to be called
3932 twice as many times as it used to be. As a result the client
3933 should be a bit faster now. Affected file is
3934 irssi/src/silc/core/silc-core.c.
3936 * Added support to Irssi SILC client of asynchronous public key
3937 verification and passphrase inquiry. Affected file is
3938 irssi/src/silc/core/silc-core.c.
3940 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Do not say "You have left channel %s" in client library.
3943 Moved it to the application. Affected files are
3944 lib/silcclient/command.c and silc/client_ops.c.
3946 * Fixed silc_client_get_clients. Command context was not
3947 duplicated and was freed memory in the callback. Affected
3948 file lib/silcclient/idlist.c.
3950 * Do not say "you are now talking..." on JOIN command in the
3951 client library. The appliation must handle it.
3953 * Do not say ".. changed topic to" in command reply in the
3954 client libary. The application must handle it.
3956 * Fixed TOPIC command sending in the client library.
3958 * Fixed a memory leak in silc_client_command_free in the file
3959 lib/silcclient/command.c.
3961 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Imported a modified version of Irssi client to the source tree.
3964 The Irssi will be used to create a new client called
3965 Irssi SILC. Imported to irssi/.
3967 Added silc_core_init_finish function to the Irssi. Affected
3968 file irssi/configure.in.
3970 A lot changes in the Makefile.ams around the irssi tree.
3972 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Do not rehash if the new size is same as the old size of the
3975 hash table, in the silc_hash_table_rehash*. The affected file
3976 lib/silcutil/silchashtable.c.
3978 * Replaced hash_table_del_by_context calls from the server
3979 (when channel->user_list and client->channels) to the
3980 hash_table_del as it is sufficient and faster.
3982 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Added silc_hash_table_list, silc_hash_table_get and the
3985 SilcHashTableList structure to provide an alternative way to
3986 traverse the hash table. The affected files are
3987 lib/silcutil/silchashtable.[ch].
3989 * Changed the server's idlist routines to use the hash table
3990 routines to optimize the code.
3992 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Replaced the client entry's `channel' list and channel entry's
3995 `user_list' list to hash tables for optimized lookup. Changed
3996 the code to use the hash table interface around the code.
3997 Affected file lib/silcd/idlist.[ch].
3999 * Added `auto_rehash' boolean argument to the function
4000 silc_hash_table_alloc to indicate whether the hash table should
4001 auto-rehash when it thinks is appropriate time. It will
4002 increase the hash table size if the there is twice as much
4003 entries in the table than the size of the table, and will
4004 decrease the size if there are twice as less entries than
4005 the size of the table.
4007 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4011 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * silc_idcache_purge_by_context deletes the entry now by context
4014 as it is supposed to do. Affected file lib/silccore/idcache.c.
4016 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4017 client is not anymore valid (WHOWAS givens the info) and not
4018 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4020 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Removed the `data' and `data_len' arguments from the ID Cache
4023 interfaces and added `name' argument. ID Cache does not handle
4024 anymore the binary data only a names associated with given ID.
4026 * When hashing a Client ID with silc_hash_id the entire ID is
4027 not hashed anymore, instead only the hash of the Client ID is
4028 hashed. This way we can access the Client ID from the cache
4029 with Client ID but with the hash of the ID (which is a hash of
4030 the nickname) as well without any difference in performance.
4032 Added also silc_idcache_find_by_id_one_ext to do one on one
4033 searching when we have the actual ID. Added also function
4034 silc_hash_client_id_compare. The affected files are
4035 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4037 * When hashing the name associated with a ID it is always done
4038 in lowercase. This way we can access the cache without worrying
4039 about case-sensitivity, even though, for example nicknames are
4042 * Fixed a bug in server with channel message sending. It put
4043 wrong ID type as destination ID. The affected file
4044 silcd/packet_send.c.
4046 * silc_idcache_del_by_context now deletes from all hash tables
4047 by context. Affected file lib/silccore/idcache.c.
4049 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Changed the client library to use the new ID Cache interface.
4052 Changes around the source tree.
4054 * Added silc_hash_table_rehash_ext to rehash with specific
4055 hash function. Affected file lib/silcutil/silchashtable.[ch].
4057 * Added silc_hash_string_compare to compare two strings in the
4058 hash table. Affected file lib/silcutil/silcutil.[ch].
4060 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Added new function silc_idcache_del_by_context into the
4063 lib/silccore/idcache.[ch].
4065 * Changed the server's ID list routines to use the new ID Cache
4066 interface. Changes around the source tree.
4068 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Added silc_hash_table_del[_by_context]_ext functions in to the
4071 lib/silcutil/silchashtable.[ch].
4073 Removed silc_hash_table_find_all* routines and added new
4074 silc_hash_table_find_foreach to replace them.
4076 Added silc_hash_table_replace_ext function as extended
4077 replacing function. Separated the simple hash table interface
4078 from the extended hash table interface in the file
4079 lib/silcutil/silchashtable.h.
4081 * Fixed minor bugs and changed it to use some of the new
4082 hash table functions in lib/silccore/idcache.c
4084 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Added new function silc_hash_table_find_all to return all keys
4087 in the hash table by the specified key. As the hash table is
4088 collision resistant it also makes it possible to have several
4089 duplicate keys in the hash table. This function may be used to
4090 find all of the keys from the hash.
4092 Added user_context arguments to the SilcHashFunction,
4093 SilcHashCompare and SilcHashDestructor to deliver user specified
4096 Added new fuctions silc_hash_table_find[_all]_ext to do
4097 extended lookup with specified hash and compare functions and
4098 specified user contexts.
4100 Added new function silc_hash_table_add_ext to add the key
4101 with specified hash function and user context.
4103 Added new function silc_hash_table_foreach to traverse all
4104 entrys in the hash table. Added SilcHashForeach callback
4107 Added new function silc_hash_table_del_by_context to delete
4108 the entry only if the context associated with the key matches.
4110 Affected files are lib/silcutil/silchashtable.[ch].
4112 * Removed silc_hash_[server/client/channel]_id and added just
4113 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4114 silc_hash_id_compare to compare two ID's using as the hash table
4115 comparison function. Added also silc_hash_data to hash
4116 binary data and silc_hash_data_compare to compare it.
4118 * Removed silc_idlist_find_client_by_hash as it is not needed
4119 anymore. Affected file silcd/idlist.[ch].
4121 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4122 to use internally the SilcHashTable. The new ID Cache is a lot
4123 faster than the old one. Some of the ID Cache interface was also
4124 rewritten and obsolete and stupid functions were removed.
4126 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Added entry_count field to the SilcHashTable to keep the number
4129 of the entries in the table. Implemented the function
4130 silc_hash_table_rehash. Added new function
4131 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4133 Fixed a minor bug in silc_hash_table_free.
4135 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4136 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4137 into the lib/silcutil/silcutil.[ch].
4139 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Implemented a collision resistant hash table into the
4142 lib/silcutil/silchashtable[ch]. See the header and the source
4143 for the SilcHashTable API.
4145 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Merged dotconf version 1.0.2 into lib/dotconf.
4149 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Do not compile anything in lib/silcsim/* if the SIM support
4152 is not enabled. The tree should now compile without problems
4155 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Compiled the SILC under cygwin. Compiled and tested briefly
4158 without problems. More tests needed. The SIMs didn't compile
4161 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4163 * Fixed possible crash in silc_get_username in the
4164 lib/silcutil/silcutil.c.
4166 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed a va_arg in silc/client_ops.c.
4170 * Oops, RC5 routines were named AES and caused some problems
4171 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4173 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Added new SilcIDIP structure into the lib/silccore/id.h and
4176 replaced the old `ip' fields from all SILC ID's to that type.
4177 This is a step towards IPv6 support.
4179 The silc_id_get_len takes now the ID as an extra argument.
4180 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4181 both IPv4 and IPv6 based ID's.
4183 The affected files are lib/silccore/id.[ch] and other files
4184 around the tree using these routines.
4186 * Removed the ID length arguments in server from various
4187 silc_server_send_notify_* routines -> they are not needed
4190 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * Fixed memory leak in silc_encode_pem_file in the file
4193 lib/silcutil/silcutil.c.
4195 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Check minor version as well in the SKE. Affected files are
4198 silcd/protocol.c and lib/silcclient/protocol.c.
4200 * Added --identifier option to the server so that an identifier
4201 can be when creating the public key for the server. Affected
4202 file is silcd/silcd.c.
4204 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4205 lib/silccrypt/silcpkcs.c.
4207 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Register default ciphers and stuff when using -C option with
4210 the server. Affected file sildc/silcd.c.
4212 * Put back the servers public key filename format, it is better
4213 than the new one. For now, the client keys are saved with the
4214 new filename format. The affected file silc/client_ops.c.
4216 * Implemented the Cipher API for the rest of the ciphers that
4217 did not implement it or implemented it the wrong way.
4219 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Register default ciphers and stuff when using the -S option
4222 in the client. Affected file silc/silc.c. Same also when
4223 creating new key pair with -C option.
4225 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Fixed the silc_verify_public_key client operation function to
4228 save the public keys differently. The fingerprint is now
4229 used as filename and not the hostname. This way also the
4230 client keys are saved uniquely and not with hostnames. The
4231 affected file is silc/client_ops.c.
4233 * Trimmed the silc_hash_fingerprint function to remove extra
4234 whitespaces from the end of the fingerprint. The affected
4235 file is lib/silccrypt/silchash.c.
4239 * Added silc_cipher_register_default function to register all
4240 default ciphers. It can be used when configuration files
4241 does not exist and the application does not want any specific
4242 ciphers in any specific order.
4244 The SilcDList is now used as silc_cipher_list dynamically
4245 allocated cipher list. Removed the static list all together
4246 and now all ciphers must be allocated to the dynamic list.
4247 The silc_cipher_alloc routine was changed to check only the
4250 All silc_cipher_* routines that used to return int returns
4253 The affected files lib/silccrypt/silccrypt.[ch].
4255 * The same thing was done to silc_hash_* as for silc_cipher_*
4256 routines. Affected files lib/silccrypt/silchash.[ch].
4258 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4259 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4260 Added also silc_pkcs_[un]register[_default] functions.
4261 Removed the data_context from the PKCS API.
4263 * Added silc_hmac_register_default function to register default
4264 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4265 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4266 to unregister all hmacs at once.
4268 * Register the default ciphers, hash functions, PKCSs and HMACs
4269 if client's configuration file does not exist. The affected
4272 * The client did not load the hash functions from the SIM
4273 modules at all. Added support for this. Affected file is
4274 silc/clientconfig.c.
4276 * When decoding public key with silc_pkcs_public_key_decode, check
4277 the supported algorithm only if PKCS are registered. Affected
4278 file lib/silccrypt/silcpkcs.c. The same was done with the
4279 silc_pkcs_private_key_decode.
4281 * Fixed the SILC List routines to keep the list always in order.
4282 It used to change the list's order when traversing the list but
4283 not it preserves the order. Affected file lib/trq/silclist.h.
4285 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added the client library to use the SilcSocketConnection's
4288 reference counter (by silc_socket_dup) to prevent the bug that
4289 the socket object may be freed underneath async operation.
4291 * The name resolv library checking fixes in the configure.in.pre.
4294 * Created new version of the protocol drafts for future
4295 development. The -03 drafts are the ones that will be changed
4296 in the trunk now and the -02 will remain as they are.
4298 * Send list of CUMODE notifys to the router when announcing
4299 the channel users to the router. Affected file silcd/server.c.
4300 If the router receiving channel founder CUMODE for a channel
4301 that already has channel founder it will send CUMODE notify
4302 to the sender to remove the channel founder rights from the
4303 announced client. Affected file silcd/packet_receive.c.
4305 * The CUMODE notify may now use Server ID as well as the entity
4306 who changes the mode. Updated protocool specs.
4308 * Updated INSTALL and README files.
4310 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * New web pages in the http://silc.pspt.fi. The pages was
4317 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Implemented the [DenyConnectin] config section in the server.
4320 Added silc_server_config_denied_conn to check whether incoming
4321 connection is denied. Affected file silcd/serverconfig.[ch].
4323 * Do not check the ports when checking the incoming configuration
4324 data if the port is 0, meaning any. Affected file is
4325 silcd/serverconfig.c.
4327 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Fixed buffer overflow in silc_string_compare in the file
4330 lib/silcutil/silcutil.c.
4332 * Fixed double free in silc_server_command_leave in the file
4335 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Fixed the version checking in the server. Affected file is
4340 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Fixed the configuration data fetching when accepting new
4343 connections in the server. Affected file silcd/server.c.
4345 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Added `sender_entry' argument to the function
4348 silc_server_packet_relay_to_channel so that we can check
4349 whether some destination actually belongs to the same route
4350 the sender belongs (ie, we must not resend the packet to the
4351 sender). Affected file silcd/packet_send.[ch].
4353 * Added `servername' field to the SilcClientEntry in the server
4354 to hold the name of the server where client is from. Affected
4355 file is silcd/idlist.h.
4357 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Moved the channel message encrypting in the router betwen
4360 router connections from silc_server_channel_message to the
4361 silc_server_packet_relay_to_channel since we want to check
4362 whether we have anybody channel before encrypting anything.
4363 Affected files silcd/packet_[receive/send].c.
4365 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Fixed the [AdminConnection] server config section to support
4368 multiple entries. Affected file silcd/serverconfig.c.
4370 * Added support into the server to check the validity of the
4371 incoming connection before executing any KE or authentication
4374 * The connection configuration is now saved to the KE and
4375 connection auth protocol contexts and not fetched anymore in
4376 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4378 * The local hosts listenning address and port is also resolved
4379 now when starting the server. We want to have the socket object
4380 to include the real address and port for the listener. Added
4381 new function silc_net_check_local_by_sock into the files
4382 lib/silcutil/silcnet.[ch].
4384 * Fixed a broadcast bug in server -> do not broadcast if we
4387 * Fixed a routing bug. Do not route broadcast packets ever.
4388 Broadcast packets must be processed always and not routed since
4389 they may be destined to some other host than yourself and thus
4390 would get routed without no good reason. Affected file is
4393 * Added function silc_server_config_is_primary_route to check
4394 whether primary router connection has been configured (a router
4395 configuration that we are initiating). If there is not, we
4396 will assume that there is only two routers in the SILC network
4397 and we will use the incoming router connection as our primary
4398 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4400 * Changed the order of the broadcasting. Broadcast _after_ the
4401 packet has been processed not before. Affected file is
4404 * Fixed a [ClientConnection] parsing bug. The port was never
4405 parsed correctly thus resulting to port 0. Affected file
4406 silcd/serverconfig.c.
4408 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4409 argument and did not set the broadcast packet flag. Affected
4410 file silcd/packet_send.c. Fixed same bug in the function
4411 silc_server_send_notify as well.
4413 * If we receive NEW_ID packet for our own ID in the server, ignore
4416 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Removed the nickname from the Private Message Payload.
4421 Updated the code and the protocol specs.
4423 * Updated protocol specs for submitting to the IETF.
4425 * Tweaked the Random Number Generator a bit. Affected file
4426 lib/silccrypt/silcrng.c. Exported a new function
4427 silc_rng_[global]_add_noise which can be used to add more
4430 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Do not parse packets with different timeout when protocol
4433 is active -> may cause problem with rekey. Affected file
4436 * When server receives signoff notify it must not create
4437 new channel key if the client is on any channels since the
4438 sender of the signoff notify will create it.
4440 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Added printing of error messages during SKE protocol from the
4443 failure packet sent by server during SKE. Affected file
4446 * Removed the client's failure_callback handling with timeout
4447 and handle it immediately when received.
4449 * The SKE library returned wrong type in SUCCESS and FAILURE
4450 packets. They must be 32 bit MSB not 16 bit MSB.
4452 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Ok, rewrote the logic of the re-key and now it seems to work.
4455 I tested it on high traffic with frequent re-keys without
4456 problems. Added hmac_receive (and renamed hmac to hmac_send)
4457 in SilcClientConnection in lib/silcclient/client.h and
4458 in SilcIDListData in silcd/idlist.h. Also, removed the
4459 SilcPacketParserContext's cipher and hmac fields as they are
4460 not needed anymore and actually caused some problems when
4461 the ciphers and hmac's changed underneath the packet parser.
4463 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4465 * If re-key protocol is active then process the incoming packets
4466 synchronously since we must assure that icoming packets encrypted
4467 with the old key is processed before the new keys is set to
4468 use. This is true other packets than for REKEY packets.
4469 Affected file silcd/server.c. The same was done to client library
4470 as well, affected file lib/silcclient/client.c.
4472 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Fixed bug in client and server to accept the force send if
4475 the packet is send from silc_[server/client]_packet_process
4476 function. Otherwise the packets are never delivered, oops.
4478 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4480 * Disable force sending of packets when REKEY protocol is active.
4481 We must assure that no packet is sent directly when rekey is
4482 performed. All packets must be sent through packet queue.
4483 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4484 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4485 function is silc_[server/client]_packet_send_real to check
4488 * Replaced the SIM paths from example config files to
4489 /usr/local/modules. Also, make install creates now
4490 /usr/local/silc/logs directory to hold all the SILC server
4493 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Made the configure.in.pre work on Solaris. Patch by salo.
4497 * Made all ciphers compatible with non-x86 machines. Defined
4498 CBC mode macros into lib/silccrypt/ciphers_def.h.
4500 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Fixed the make install.
4504 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * When MAC computation fails the silc_packet_decrypt returned 0
4507 even though it was supposed to return -1. Fixed this. The
4508 affected file is lib/silccore/silcpacket.c.
4510 * Do not replace the config files in /etc/silc (in make install)
4511 if they already exist. Affected file ./Makefile.am.
4513 * Do not send re-key packets immediately but through packet queue.
4514 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4516 * Changed silc_net_check_host_by_sock to return FALSE if the
4517 IP/DNS could not be resolved. Though, it returns the IP address
4518 now even if it could not resolve it (but returns also FALSE).
4519 Affected file lib/silcutil/silcnet.[ch].
4521 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Added silc_pkcs_decode_identifier to decode the public key's
4524 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4525 Added also silc_pkcs_free_identifier. Added also new context
4526 SilcPublicKeyIdentifier.
4528 * Added -S option to the silc client. It is used to dump the
4529 contents of the specified public key file.
4531 * Changed the PKCS api to return the public key length when
4532 setting the public key.
4534 * Fixed a fatal bug in the public and private key file loading.
4535 Affected file lib/silccrypt/silcpkcs.c.
4537 * Execute the packet parsing for client with zero (0) timeout
4538 if the protocol is active. Affected file silcd/server.c.
4540 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Made the key generation options to the silcd program. Added
4543 -C option, equivalent to client's option.
4545 * Added new [ServerKeys] config section to the server. It
4546 configures the server's public and private key.
4548 * Defined generic Public Key Payload into the protocol
4549 specification to send specific type of public keys and
4552 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4553 public key or certificate.
4555 * Implemented the GETKEY command to the server and to the
4556 client library and on user interface.
4558 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Made preliminary `make install' work.
4562 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Added SilcServerRekey context into silcd/idlist.h.
4566 * Added the PFS support as defined in the specification to the
4567 SKE protocol. Affected files lib/silcske/*.c.
4569 * Added `ske_group' field to the SilcServerRekey context to hold
4570 the number of the SKE group that is used with PFS in re-key.
4571 Affected file silcd/idlist.h.
4573 * Added PFS re-key support to the server. Affected file is
4576 * Added silc_protocol_cancel to cancel execution of the next
4577 state of the protocol. Affected file is
4578 lib/silccore/silcprotocol.[ch].
4580 * Added the re-key support with and without PFS to the client
4581 library. Re-key is performed once in an hour, by default.
4583 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4584 Added silc_client_rekey_callback and silc_client_rekey_final.
4585 Affected files are lib/silcclient/protocol.[ch] and
4586 lib/silcclient/client.[ch].
4588 * Removed the `hmac_key' and `hmac_key_len' fields from the
4589 SilcClientConnection structure; not needed. Affected file is
4590 lib/silcclient/client.h.
4594 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Do not ask whether user wants to use the negotiated private key
4597 for private messages, just use it. Affected file is
4598 silc/local_command.c.
4600 * Added `send_enc_key' and `enc_key_len' fields to the
4601 SilcIDListData structure since they are needed in the re-key
4602 phase. Affected file is silcd/idlist.[ch].
4604 * Implemented the simple re-key protocol into the server.
4605 Affected files silcd/server.c and silcd/protocol.[ch]. The
4606 re-key will be performed once in an hour, by default.
4608 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4609 Added silc_server_rekey, silc_server_rekey_callback and
4610 silc_server_rekey_final.
4612 * Removed Tunneled flag from the protocol. Updated the code
4613 and the specifications.
4615 * Adde `pfs' field to the SilcIDListData to indicate whether
4616 the PFS is to be performed in the re-key. Affected file is
4619 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4622 int64 of at least the xintXX size. If void * is less that 4
4623 bytes uint32 * will be used. Defined bool as boolean.
4625 * Changed _ALL_ unsigned long and unsigned int to uint32,
4626 unsgined short to uint16 in the source tree.
4628 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4629 not handle clients that has entry->data.registered == FALSE.
4630 They are not in the network anymore. Affected file is
4633 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Implemented the sending of the SERVER_SIGNOFF notify in the
4636 server. Affected file is silcd/server.c.
4638 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4639 Added also silc_notify_payload_encode_args into the
4640 lib/silccore/silcnotify.[ch].
4642 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4643 Affected file silcd/packet_receive.c.
4645 * Implemented the SERVER_SIGNOFF notify handling in the client
4646 library. Affected file lib/silcclient/client_notify.c. Also,
4647 implemnted the printing of the SERVER_SIGNOFF info to the
4648 application. Affected file silc/client_ops.c.
4650 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4651 if the deleting was successful. Affected file silcd/idlist.[ch].
4653 * Added support for public key authentication in the connection
4654 authentication protocol in the client library. Affected file
4655 lib/silcclient/protocol.c.
4657 * Changed the server's silc_idlist_get_clients_by_* interface
4658 to support already allocated array so that new entries may be
4659 added to pre-allocated array. Affected file silcd/idlist.[ch].
4660 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4661 and command replies.
4663 * All command reply functions in the server now calls the
4664 pending command callback even if error occured. This way the
4665 error will be delivered to the client as well. Affected files
4666 silcd/command.c and silcd/command_reply.c.
4668 * Fixed INFO command to return local server's info if no server
4669 was provided. Affected file lib/silcclient/command.c.
4671 * Removed RESTART command for good. Updated the code and the
4674 * Rewrote parts of the task system. It is a bit simpler now.
4675 Removed unsued task priorities. The affected files are
4676 lib/silcutil/silctask.[ch].
4678 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Moved the USERS printing from the library to the application.
4681 Affected files lib/silcclient/command.c and silc/client_ops.c.
4683 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Added channel key re-key support. The re-key is perfomed
4688 only by the router and is done once in an hour. Added `rekey'
4689 field to the SilcChannelEntry in the server. Affected files
4690 silcd/server.c and silcd/idlist.h.
4692 * Added silc_task_unregister_by_context into the file
4693 lib/silcutil/silctask.[ch].
4695 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Added SILC_UMODE_GONE mode to indicate when the client is not
4698 present in the SILC network. Added also support to the local
4699 command AWAY that will set this mode. Added support of showing
4700 "xxx is gone" in WHOIS command. The USERS command shows the
4701 gone status as well.
4703 * Fixed setting server and router operator privileges in the
4704 server's UMODE command. Affected file silcd/command.c.
4706 * Merged the SKE KE1 and KE2 payloads into one payload. The
4707 new KE payload is equivalent to the old KE2 payload.
4709 Cleaned up the SKE Start Payload parsing. It now uses the
4710 simple buffer unformatting to do the parsing. A lot faster
4713 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4714 to the SKE that is used to indicate whether both of the SKE
4715 parties should perform authentication. By default only the
4716 responder performs authentication. By setting this flag also
4717 the initiator must do authentication. By default it is unset
4718 since in normal SKE case, client to server connection, only
4719 the responder should do authentication. When doing SKE between
4720 two clients both should perform authentication. Updated the
4721 code and the protocol specs.
4723 * A little fix to IDENTIFY command in the server. Search the
4724 client first by hash not nickname. Affected file is
4727 * Fixed the silc_client_close_connection to support closing
4728 the client to client connections wihtout deleting too much
4729 data. Affected file lib/silcclient/client.c.
4731 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4732 are received if protocol used to be active but is not anymore
4733 the application would crash due to NULL pointer dereference.
4734 Affected files silcd/server.c and lib/silcclient/client.c.
4736 * Added `hash' field to the SilcClientConnection to include
4737 the hash function negotiated in the SKE protocol.
4739 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4740 to set the channel founder authentication data. A client can
4741 claim the founder rights later by providing the authentication
4742 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4743 This way the channel founder can regain the channel founder
4744 privileges even it is left the channel. This works only on
4745 local server and the client must be connected to the same
4746 server to be able to regain the founder rights. Updated the
4747 protocol specs accordingly.
4749 Added support to the CMODE command in the client to set the
4750 founder auth data. Read the README to see how to set it.
4752 Added support to the CUMODE command to claim the founder
4753 rights. Read the README to see how to do it.
4755 Added support for the founder authentication to the Channel
4756 Entry in the server. Affected file silcd/idlist.h.
4758 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4759 server's CMODE command. Affected file silcd/command.c.
4761 * Added the following new functions into lib/silccore/silcauth.[ch]:
4762 silc_auth_get_method and silc_auth_get_data.
4764 * The server now saves the remote hosts public key to the
4765 SilcIDListData pointer. Affected file silcd/protocol.c.
4767 * The normal server now does not remove the channel entry from
4768 the cache if the founder authentication data is set. It used
4769 to remove it if the founder was the last one on the channel on
4770 the server and left the channel. The auth data is saved and
4771 if the channel is re-joined later the old entry is used with
4772 the old auth data. Affected files silcd/command_reply.c and
4775 * Removed the `pkcs' field from the SilcIDListData structure
4776 in the server; it is not used. Affected file silcd/idlist.h.
4778 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Fixed packet processing on slow links. Partial packets were
4781 never re-processed because the incoming data buffer was cleared
4782 by the application. Application must not directly clear the
4783 sock->inbuf, the packet processing routines handle it. Fixed
4784 this in client library and in server.
4786 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Fixed the WHOIS and IDENTIFY send reply function to really
4789 check whether to send list or just one entry. Affected file
4792 * Cleaned up the LEAVE command's channel key distribution. The
4793 affected file silcd/command.c.
4795 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4796 can enforce the channel mode as well. In that case the ID
4797 includes the ID of the server. The code now enforces the
4798 mode change if the router have different mode than the server.
4800 * The notify client operation with CMODE_CHANGE notify can now
4801 return NULL client_entry pointer if the CMODE was not changed
4802 by client. Application must check for this.
4804 * Added <Server ID> argument to INFO command to support server
4805 info fetching by Server ID.
4807 * Added silc_server_announce_get_channel_users to get assembled
4808 packets of channel users of the specified channel. Affected
4809 file silcd/server.[ch].
4811 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4812 was freed underneath the ID Cache.
4814 * Re-announce clients when the server received CHANNEL_CHANGE
4815 notify from the router. Affected file silcd/packet_send.c.
4817 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4820 crashed since it did not handle the fact that there is no cipher
4821 called "3" and didn't check the error condition. Now fixed.
4823 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4824 flag. It can be used to send message requests.
4826 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Implemented the RESTART command in the client.
4830 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4831 notice type messages. Added notice printing to the user
4834 * The channel keys are not re-generated if the channel's mode
4835 is PRIVKEY, ie private key on the channel exists. Affected
4836 files silcd/server.c and silcd/command.c.
4838 * Fixed a little bug in channel message delivery when channel
4839 private keys are set in the server. Affected file is
4840 silcd/packet_send.c.
4842 * Changed the setting on channel->on_channel = TRUE from the
4843 silc_client_save_channel_key to the JOIN command reply. The
4844 key payload is not received if the private channel key is set.
4845 Affected file lib/silcclient/command_reply.c and the
4846 lib/silcclient/client_channel.c.
4848 * When the CMODE_CHANGE notify is sent and the channel private
4849 key mode is removed the channel key must be re-generated in
4850 other cells as well. Added this support for the router in the
4851 silcd/packet_receive.c.
4853 * Added new local command NOTICE to send notice message on
4854 channel. Affected file silc/local_command.[ch].
4856 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Added new local command ME to the client. It is used to send
4859 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4860 some action. Affected file silc/local_command.[ch].
4862 * Changed channel_message and private_message client operations
4863 to deliver the message flags to the application. Added also
4864 the `flags' arguments to the silc_client_send_channel_message
4865 and silc_client_send_private_message functions. Affected file
4868 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Redefined the Private Message Payload to support private message
4871 keys and to support the new private message flags. Updated
4872 the protocol specs. Flags makes it possible to have for example
4873 CTCP style messages.
4875 * Added new type SilcPrivateMessagePayload and defined an API
4876 for it in the lib/silcclient/silcprivate.[ch].
4878 * Tested private message private keys successfully. Tested the
4879 private message key set, unset and list commands with the new
4882 * Redefined the Channel Message Payload to include the channel
4883 message flags (equal with private message flags) to support
4884 for example CTCP style messages.
4886 * Defined some of the message (for channel and private message)
4887 flags. Updated the protocol specs and added the flags to the
4888 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4890 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added SilcKeyAgreementStatus type to the key agreement routines
4893 to indicate the current status and error if one occured.
4894 The status types are defined in the lib/silcclient/silcapi.h.
4896 * Added new local command KEY that is used to set and unset private
4897 keys for channels, set and unset private keys for private messages
4898 with remote clients and to send key agreement requests and
4899 negotiate the key agreement protocol with remote client. The
4900 key agreement is supported only to negotiate private message keys,
4901 it currently cannot be used to negotiate private keys for channels,
4902 as it is not convenient for that purpose.
4904 * Fixed a minor pending callback setting bug in the function
4905 silc_client_get_client_by_id_resolve, now the function works.
4906 Affected file lib/silcclient/idlist.c.
4908 * Added function silc_net_get_local_port to get local bound
4909 port by socket. Added to lib/silcutil/silcnet.[ch].
4911 * Added `sockets' and `sockets_count' fields to the SilcClient
4912 object. They hold the sockets of the listenning sockets in
4913 the client. Listenning sockets may be for example the key
4914 agreement server. Affected file lib/silcclient/client.[ch].
4915 Added functions the silc_client_add_socket and the
4916 silc_client_del_socket. They are exported to the application
4919 * Added ~./silc/clientkeys to support other client's public keys.
4921 * Renamed verify_server_key client operation to verify_public_key
4922 and added one argument to indicate the type of the connection
4923 (server, client etc.).
4925 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Added silc_server_connection_auth_request to handle the
4928 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4929 silcd/packet_receive.[ch].
4931 * Added silc_server_send_connection_auth_request into the
4932 silcd/packet_send.c to send the connection auth request packet.
4934 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4937 * Fixed the public key authentication in responder side in the
4938 server. The `auth_data' pointer includes the SilcPublicKey
4939 not the path to the public key. Affected file silcd/protocol.c.
4941 * Implemented the public key authentication in the initiator side
4942 in the server. Affected file silcd/protocol.c.
4944 * Removed the [RedirectClient] config section from the server
4945 configuration. Is not needed and I don't want to implement it.
4947 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Cleaned up the CMODE command in the server. It now works
4950 correctly and supports all the modes defined in the protocol.
4951 Affected file is silcd/command.c.
4953 * Added `hmac_name' field to the SilcChannelEntry in the server
4954 to hold the default HMAC of the channel. It can be set when
4955 creating the channel (with JOIN command). Affected files
4958 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4959 type to indicate the change of the current cipher and hmac
4960 on the channel. Client can safely ignore the <cipher> argument
4961 (if it chooses to do so) since the CHANNEL_KEY packet will
4962 force the channel key change anyway. The <hmac> argument is
4963 important since the client is responsible of setting the new
4964 HMAC and the hmac key into use.
4966 * Fixed the CMODE command in the client library as well.
4968 * Tested CMODE command in router environment successfully.
4970 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Show the version of the remote client (or server) when connecting
4973 to the server. It is logged to the log file. Affected file
4974 is silcd/protocol.c.
4976 * Fixed the KILLED notify handling in the client library. The
4977 client must be removed from all channels when receiving the
4980 Also, do not remove the client entry when giving the KILL
4981 command but when the KILLED notify is received.
4983 * Removed silc_idlist_find_client_by_nickname from the server.
4984 Not needed anymore. Affected files silcd/idlist.[ch].
4986 * Implemented the CHANNEL_CHANGE notify type handling to the
4987 server. Affected file silcd/server.c.
4991 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4993 * Added silc_server_send_notify_invite to send the INVITE
4994 notify between routers.
4996 * Implemented the INVITE command correctly to the server.
4998 * Implemented the INVITE notify type handling in the server.
5000 * Implemented the INVITE command to the client library and on the
5003 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Added function silc_server_get_client_resolve to find the
5006 client entry by ID from all ID lists and then resolve it
5007 (using WHOIS) if it cannot be found. Affected file is
5010 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Implemented the BAN command to the client library.
5014 * The JOIN command in the server now checks the invite list
5017 * Changed the silc_command_reply_payload_encode_va and the
5018 silc_command_payload_encode_va to support that if argument is
5019 NULL it ignores and checks the next argument. Affected file
5020 lib/silccore/silccommand.c.
5022 * Added silc_server_send_notify_ban to send the BAN notify
5023 type between routers.
5025 * Chaned the silc_notify_payload_encode to support that if
5026 argument is NULL it ignores and checks the next argument.
5027 Affected file lib/silccore/silcnotify.c.
5029 * Tested ban lists in router environment successfully.
5031 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Implemented BAN command to the server, in silcd/command.[ch].
5035 * Removed the BAN and INVITE_LIST modes from the CMODE command
5038 * Added function silc_string_match to regex match two strings.
5039 Affected files lib/silcutil/silcutil.[ch].
5041 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Redefined parts of the SilcChannelEntry in the server to support
5044 the new ban and invite lists.
5046 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Redefined the INVITE command. The same command can be used to
5049 invite individuals to the channel but also to manage the invite
5050 list of the channel (to add to and remove from the invite list).
5051 Updated the protocol specs.
5053 * Added new command SILC_COMMAND_BAN that can be used to manage
5054 the ban list of the channel. Updated the protocol specs.
5056 * Removed the channel modes: the SILC_CMODE_BAN and the
5057 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5058 in the CMODE command. The equivalent features are now available
5059 using INVITE and BAN commands. Updated the protocol specs.
5061 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5062 in the network about change in the current ban list. The notify
5063 type is not used by the client.
5065 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5066 support the invite lists.
5068 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Added new function silc_string_regexify that converts string
5071 including wildcard characters into regex string that can
5072 be used by the GNU regex library. Added into the file
5073 lib/silcutil/silcutil.[ch].
5075 Added silc_string_regex_combine to combine to regex strings
5076 into one so that they can be used as one regex string by
5077 the GNU regex library. Added into the file
5078 lib/silcutil/silcutil.[ch].
5080 Added silc_string_regex_match to match two strings. It returns
5081 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5083 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Imported GNU regex to the soruce tree into lib/contrib.
5086 Fixed some compiler warning from the regex.c.
5088 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Fixed MOTD command in the server to work in router environment.
5092 * Fixed the MOTD command in the client library to support
5093 the server argument in the command.
5095 * Added `nickname_len' argument to the silc_idlist_add_client
5096 in the server, as the `nickname' argument may be binary data
5099 * Added silc_idlist_get_channels to return all channels from
5102 * Implemented LIST command to the server. Affected file is
5105 * Implemented the LIST command to the client library and on the
5108 * Added [<user count>] argument to the LIST command reply.
5109 With private channels the user count is not shown.
5111 * Updated TODO and README.
5113 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * The client entry's data.registered must be TRUE even with
5116 global client entry on global client list. The data.registered
5117 is used to check whether the client is anymore in the network,
5118 for example with WHOWAS command so it must be valid.
5120 * Fixed the WHOWAS command in the server. It now actually works
5121 in router environment. Added function into silcd/command_reply.c
5122 silc_server_command_reply_whowas_save.
5124 * Added silc_idlist_purge function to the silcd/idlist.c
5125 to periodically purge the ID Cache.
5127 * Fixed INFO command in the server. It works now in router
5128 environment. Added <server name> argument to the INFO command
5129 reply. Updated the protocol specs.
5131 * Fixed minor bug in silc_idcache_purge to not purge if the
5132 expire value is zero.
5134 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5135 they were buggy because of the WHOWAS information.
5137 * Fixed local command MSG to handle the async resolving of
5138 the remote client properly. It used to fail the first MSG.
5139 Affected file silc/local_command.c.
5141 * Added `data_len' field to SilcIDCache context.
5143 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Update TODO. Todo in commands in the server.
5147 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5150 used by routers as broadcast packet to inform other routers
5151 about the changed user mode.
5153 Implemented the notify handling in the server. Affected file is
5154 silcd/packet_receive.c. Added the function
5155 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5157 * Added new generic Channel Payload and deprecated the New Channel
5158 Payload. The New Channel Payload is now the generic Channel
5161 * Added new argument `mode' to the silc_server_send_new_channel
5162 as it is required in the Channel Payload now.
5164 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5165 and created a new and real SilChannelPayload to represent the
5166 new generic Channel Payload. Implemented the encode/decode
5167 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5169 * Added silc_server_get_client_channel_list to return the list
5170 of channels the client has joined for WHOIS command reply.
5171 Affected file silcd/server.[ch].
5173 * Implemented the channel list sending in the WHOIS command reply
5174 in server and in the client.
5176 Implemented the channel list displaying on the user interface
5177 as well. Affected file silc/client_ops.c.
5179 * Added silc_channel_payload_parse_list to parse list of Channel
5180 Payloads. It returns SilcDList list of SilcChannelPayloads.
5181 Client for example can use this function to parse the list of
5182 channels it receives in the WHOIS command reply. The caller
5183 must free the list by calling silc_channel_payload_list_free.
5184 Affected files lib/silccore/silcchannel.[ch].
5186 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Added one new argument <user mode> to the WHOIS command reply
5189 to return the mode of the user in SILC. Updated the protocol
5192 Implemented it to the server and client.
5194 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Fixed the mode printing on the user interface on joining.
5197 Affected file silc/client_ops.c.
5199 * Implemented the UMODE command and user modes in general to the
5200 client library and to the user interface.
5202 * Implemented the UMODE command to the server.
5204 * The server now sends UNKNOWN_COMMAND error status if client sends
5205 unknown command. Affected file silcd/command.c.
5207 * All server commands now handle the command identifier the right
5208 way when sending the command reply to the client. The client can
5209 use to identify the command replies with the identifier.
5211 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Added silc_server_get_client_route to resolve the route to
5214 the client indicated by the client ID. Affected file is
5217 * Added silc_server_relay_packet as general function to relay
5218 packet to arbitrary destination. This deprecates functions
5219 like _send_private_message_key, _relay_notify etc. Affected
5220 file is silcd/packet_send.[ch].
5222 Removed silc_server_send_key_agreement,
5223 silc_server_send_private_message_key and
5224 silc_server_packet_relay_notify functions from the file
5225 silcd/packet_send.[ch].
5229 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5230 server. Affected file silcd/packet_receive.[ch].
5232 * Implemented the KILL command to the client. Implemented the
5233 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5234 Affected files lib/silcclient/command[_reply].c and
5235 lib/silcclient/client_notify.c. Implemented the KILL notify
5236 printing in the user inteface.
5238 * Fixed a lot silc_parse_nick memory leaks from the client
5239 library in the file lib/silcclient/command.c.
5241 * Changed the silc_server_send_notify_on_channels's `sender'
5242 argument from SilcSocketConnection to SilcClientEntry to
5243 check the sender as entry and not as connection object and not
5244 to send to the client provided as argument. The affected file
5245 is silcd/packet_send.[ch].
5247 * The notify packets that are destined directly to the client used
5248 to not to be processed by the server. Now changed that and the
5249 server processes all notify packets. After relaying the packet
5250 to the client the notify packet is processed in the server.
5252 * The silc_server_free_client_data now checks whether there is
5253 pending outgoing traffic for the client and purges the data to
5254 the network before removing the client entry.
5256 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5259 an client is killed from the SILC Network. Updated the protocol
5262 Added new function silc_server_send_notify_killed to the
5263 silcd/packet_send.[ch].
5265 * Added function silc_server_packet_relay_notify to relay notify
5266 packets that are destined directly to a client. In this case
5267 the server does not process the notify packets but merely relays
5268 it to the client. Affected file silcd/packet_send.[ch].
5270 Added also silc_server_packet_process_relay_notify to check
5271 whereto relay the notify. Affected file is
5272 silcd/packet_receive.[ch].
5274 * Implemented the KILL command to the server.
5278 * Added the backup schema desgined last fall to the protocol
5279 specs for everyone to see. The specification is in the
5280 *-spec-xx.txt draft and the packet type definitions for the
5281 backup routers is in *-pp-xx.txt draft. Thusly, added also
5282 new packet type SILC_PACKET_CELL_ROUTERS.
5284 * A big security problem in the implementation discovered. The
5285 signoff of an client did not cause new channel key generation
5286 which it of course should've done. The channel keys must be
5287 always re-generated when client leaves (or signoffs) the channel.
5288 The silc_server_remove_from_channels funtion now handles
5289 the channel key re-generation.
5291 * Added `sender' argument to the silc_server_send_notify_on_channels
5292 to not to send the client provided as argument. Affected file
5293 silcd/packet_send.[ch].
5295 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Implemented OPER and SILCOPER commands into the server and
5300 * Added silc_auth_verify and silc_auth_verify_data to verify
5301 the authentication directly from the authentication payload.
5302 It supports verifying both passphrase and public key based
5303 authentication. Affected file lib/silccore/silcauth.[ch].
5305 * Added `hash' field to the SilcIDListData structure. It is the
5306 hash negotiated in the SKE protocol. Affected file is
5309 * Slight redesigning of the SilcAuthPayload handling routines.
5310 Do not send SilcPKCS but SilcPublicKey as argument.
5312 * Implemented the public key authentication support to the
5313 serverconfig. The public key is loaded from the provided path
5314 and saved as authentication data to void * pointer. Thus,
5315 changed the unsigned char *auth_data to void *auth_data;
5317 * Fixed SHUTDOWN command to send the reply before the server
5318 is shutdown. :) Affected file silcd/command.c.
5320 * Fixed fatal bug in CONNECT command. The hostname was invalid
5321 memory and server crashed. Affected file silcd/command.c.
5323 * Fixed fatal bug in CLOSE command. The server_entry became
5324 invalid but was referenced later in the command. Affected file
5327 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Fixed fatal bug in failure packet handling. Server ignored
5330 the failure and thus crashed when it came.
5334 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5337 that the command may be executed only once in (about) 2 seconds.
5338 The old SILC_CF_LAG flag is same but allows command bursts up
5339 to five before limiting.
5341 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5342 server code. Various commands now includes the CF_LAG_STRICT
5343 flag to disallow any kind of miss-use of the command.
5345 * Fixed the silc_buffer_unformat to not to allocate any data
5346 if the length of the data is zero. It used to allocate the
5347 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5349 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5351 * Changed the format of AdminConnection configuration section
5352 in the server. Added username of the admin to the format.
5353 Affected files silcd/serverconfig.[ch].
5355 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5356 to return admin configuration data by host, username and/or
5359 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Implemented WHOWAS command to the server. Added the functions:
5363 silc_server_command_whowas_parse,
5364 silc_server_command_whowas_send_reply,
5365 silc_server_command_whowas_from_client and
5366 silc_server_command_whowas_from_server
5368 * Added <Client ID> argument to the WHOWAS command reply. Updated
5369 the protocol specs accordingly.
5371 * Implemented WHOWAS command and command_reply to the client
5374 Implemented the WHOWAS printing on the user interface.
5376 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Added new argument to the WHOWAS command reply, the real name.
5379 It is an optional argument. Updated the protocol specs.
5381 * Added SilcIDCacheDestructor callback that is registered when
5382 the SilcIDCache is allocated. The callback is called when
5383 an cache entry in the ID Cache expires, or is purged from the
5384 cache. Added into lib/silccore/idcache.[ch].
5386 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5387 to destruct the client entries when the cache entry expires.
5388 Other ID Cache's in server and in the client library ignores
5391 * If the ID Cache entry's `expire' field is zero then the entry
5392 never expires. Added boolean `expire' argument to the
5393 silc_idcache_add function in the lib/silccore/idcache.[ch].
5394 If it is TRUE the default expiry value is used.
5396 * Added silc_server_free_client_data_timeout that is registered
5397 when client disconnects. By default for 5 minutes we preserve
5398 the client entry for history - for WHOWAS command.
5400 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Added support to the server to enforce that commands are not
5403 executed more than once in 2 seconds. If server receives
5404 commands from client more frequently, timeout is registered
5405 to process the commands. Affected file silcd/command.c.
5406 Added new function silc_server_command_process_timeout.
5408 * Changed NICK_NOTIFY handling in client library to check that
5409 if the client's nickname was changed, so there is no need to
5410 resolve anything from the server.
5412 * Removed error printing from the WHOIS and IDENTIFY commands.
5413 If error occurs then it is ignored silently in the client library.
5414 The application, however, may map the received error to
5415 human readable error string. The application currently maps
5416 the NO_SUCH_NICKNAME error to string.
5418 * Made the command status message public to the application. Moved
5419 them from lib/silcclient/command_reply.c to
5420 lib/silcclient/command_reply.h. The application can map the
5421 received command status to the string with the
5422 silc_client_command_status_message function.
5424 * Added check to the server to check that client's ID is same
5425 as the Source ID in the packet the client sent. They must
5428 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Added dist-bzip hook to the Makefile.am to make bzip2
5431 compressed distributions.
5433 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Server now enforces the maximum length for the nickname and
5436 the channel as protocol specification dictates. 128 bytes for
5437 nickname and 256 bytes for channel name.
5439 * Moved the WHOIS printing to the application. The client libary
5440 does not print out the WHOIS information anymore, the application
5441 must do it. Renamed silc_client_command_reply_whois_print to
5442 the silc_client_command_reply_whois_save.
5444 The client's idle time is also sent to the application now, and
5445 the idle is shown on screen.
5447 * Added silc_client_command_reply_identify_save to save the
5448 received IDENTIFY entries.
5450 * Do not check for channel private keys in message sending and
5451 reception if the channel does not have the PRIVKEY mode set.
5452 Affected file lib/silclient/client_channel.c.
5454 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5457 just surfaced after chaning the JOIN procedure.
5459 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Added silc_client_get_clients_by_list to get client entries
5462 from Client ID list, that is returned for example by JOIN
5463 and USERS command replies. The application should use this
5464 function for example when JOIN command reply is received to
5465 resolve the clients already on the channel (library does not
5466 do that anymore as USERS command reply is not used in the JOIN
5467 procedure anymore). Affected files lib/silcclient/silcapi.h and
5468 lib/silcclient/idlist.c.
5470 * JOIN command reply and USERS command reply returns now SilcBuffer
5471 pointers instead of unsigned char pointers when returning
5472 the client list and mode list.
5474 * Added <Client ID> argument to the JOIN command reply, mainly
5475 for the server to identify for which client the command was
5476 originally sent. Updated protocol specs accordingly.
5478 * Added SilcDlist private_key pointer to the SilcChannelEntry
5479 in the client to support the channel private keys. Affected
5480 file is lib/silcclient/idlist.h.
5482 * Added SilcChannelPrivateKey argument to the function
5483 silc_client_send_channel_message so that application can choose
5484 to use specific private ke if it wants to. If it is not provided,
5485 the normal channel key is used, unless private keys are set.
5486 In this case the first (key that was added first) is used
5487 as the encryption key.
5489 * Implemented the support for channel private key handling.
5490 Implemented the following functions:
5492 silc_client_add_channel_private_key,
5493 silc_client_del_channel_private_keys,
5494 silc_client_del_channel_private_key,
5495 silc_client_list_channel_private_keys and
5496 silc_client_free_channel_private_keys
5498 Affected file lib/silcclient/client_channel.c.
5500 * Added the support for the private keys in the channel message
5501 sending and encryption and in the message reception and
5502 decryption. Affected funtions are
5503 silc_client_send_channel_message and silc_client_channel_message.
5505 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Added SKE's key verify callback to the client library's
5508 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5510 * Removed the statement that server (or router) must send USERS
5511 command reply when joining to the channel so that the client
5512 knows who are on the channel. Instead, the client list and
5513 client's mode list is now sent in the JOIN command reply to the
5514 client who joined channel. This is better solution.
5516 * Added function silc_server_get_users_on_channel and function
5517 silc_server_save_users_on_channel to the silcd/server.[ch].
5519 * Removed function silc_server_command_send_users from the
5522 * Do not show topic on the client library anymore. The topic is
5523 sent in the command reply notify to the application and the
5524 application must show the topic now.
5526 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Added client searching by nickname hash into the IDENTIFY and
5529 WHOIS commands in the server as they were clearly missing from
5530 them. Affected file is silcd/command.c.
5532 * Fixed a bug in private message receiving in the client library.
5533 The remote ID was freed and it wasn't supposed, now it is
5536 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Minor fix to the channel payload; allocate the data area, as it
5539 needs to be of specific length.
5541 * If the key agreement port is zero then the operating
5542 system will define the bound port. Affected files are
5543 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5545 * Added new function silc_channel_payload_decrypt into the file
5546 lib/silccore/silcchannel.[ch].
5548 * Moved the channel message etc, check from silc_packet_decrypt
5549 to applications. The library calls now a generic
5550 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5551 when the packet is either normal or special. This was done to
5552 allow more wide range of checking that was not allowed when
5553 the code was in library. Now applications can do virtually any
5554 checks to the packet and return to the library the decision how
5555 the packet should be processed. Affected files are
5556 lib/silccore/silcpacket.[ch].
5558 Added silc_server_packet_decrypt_check to the server and
5559 silc_client_packet_decrypt_check to the client library.
5561 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5562 to send with specified source and destination information.
5564 * Channel message delivery between routers was broken after the
5565 channel key distribution was fixed earlier. The channel key
5566 was used be to distributed to other routers as well which is not
5567 allowed by the protocol. Now this is fixed and channel keys
5568 really are cell specific and the channel message delivery between
5569 routers comply with the protocol specification.
5571 * Fixed various commands in server to check also the global list
5572 for the channel entry and not just the local list. The affected
5573 file silcd/command.c.
5575 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Added assert()s to buffer formatting and unformatting routines
5578 to assert (if --enable-debug) when error occurs. Affected
5579 file: lib/silcutil/silcbuffmt.c.
5581 * Changed to auto-reconnect to check whether the remote host is
5582 router and register the re-connect timeout if it is. It used
5583 to check that whether we are normal server, but router must do
5584 auto-reconnect with another router as well. Affected file
5587 * Removed the [<key len>] option from CMODE command as the cipher
5588 name decides the key length, nowadays. See the defined ciphers
5589 from the protocol specification.
5591 * Added [<hmac>] option to the CMODE command to define the HMAC
5592 for the channel. Added SILC_CMODE_HMAC channel mode.
5594 * Added [<hmac>] option for the JOIN command so that user can
5595 select which HMAC is used to compute the MACs of the channel
5598 * Added Hmac field to the Channel Message Payload. The integrity
5599 of plaintext channel messages are now protected by computing
5600 MAC of the message and attaching the MAC to the payload. The
5601 MAC is encrypted. Now, it is clear that this causes some
5602 overhead to the size of the packet but rationale for this is that
5603 now the receiver can verify whether the channel message decrypted
5604 correctly and also when private keys are set for the channel the
5605 receiver can decrypt the packet with several keys and check from
5606 the MAC which key decrypted the message correctly.
5608 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5609 lib/silccrypt/silccipher.[ch].
5611 * Added silc_hash_len to return the digest length into the
5612 lib/silcrypt/silchash.[ch].
5614 * Rewrote parts of Silc Channel Payload interface in the
5615 lib/silccore/silcchannel.[ch]. The encode function now also
5616 encrypts the packet and parse function decrypts it.
5618 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Fixed a minor formatting bug in the SKE's key material processing.
5621 It actually might have processed the keys wrong way resulting
5624 * Redefined the mandatory HMAC algorithms and added new algorithms.
5625 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5626 and hmac-md5 truncated to 96 bits. The mandatory is now
5627 hmac-sha1-96. Rest are optional (including the one that used
5628 to be mandatory). Rationale for this is that the truncated HMAC
5629 length is sufficient from security point of view and can actually
5630 make the attack against the HMAC harder. Also, the truncated
5631 HMAC causes less overhead to the packets. See the RFC2104 for
5634 * Added new [hmac] configuration section. The SKE used to use
5635 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5636 is of course wrong. The official names that must be proposed in
5637 the SKE are the ones defined in the protocol specification
5638 (hmac-sha1-96 for example). The user can configure any hmac
5639 using any hash function configured in the [hash] section. At
5640 least, the mandatory must be configured.
5642 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5644 * Added HMAC list to the SKE proposal list. It has now both
5645 hash algorithm list and HMAC list. This makes the protocol
5646 incompatible with previous versions. The SKE now seems to work
5647 the way it is supposed to work, for the first time actually.
5649 * Defined plain Hash algorithms to the protocol specification.
5652 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Implemented support for key agreement packets into the server.
5655 Added functions silc_server_key_agreement and
5656 silc_server_send_key_agreement. Other than these functions,
5657 server has nothing to do with this packet.
5659 * Added support for private message key packets into the server.
5660 Added functions silc_server_private_message_key and
5661 silc_server_send_private_message_key.
5665 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5666 called in the protocol's final callback instead in the END
5667 protocol state. This makes a little more sense and in the same
5668 time in client we can use the same protocol routines for normal
5669 key exchange and to key agreement packet handling as well.
5671 * Added to both client's and server's KE protocol context the
5672 SilcSKEKeyMaterial pointer to save the key material. We will
5673 bring the key material to the protocol's final callback by doing
5674 this. The final callback must free the key material.
5676 * Added SKE's packet_send callback into client's KE protocol
5677 context so that the caller can choose what packet sending function
5678 is used. This way we can use different packet sending when
5679 doing normal SKE when doing key agreement packet handling (in
5680 the key agreement packet handling we do not want to encrypt
5683 * Implemented the responder side of the key agreement routines
5684 in the client. The client can now bind to specified port and
5685 accept incoming key negotiation. The key material is passed
5686 to the application after the protocol is over.
5688 * Implemented the processing of incoming Key Agreement packet
5689 in the client. Added function silc_client_key_agreement to
5692 * Implemented the intiator side of the key agreement routines
5693 in the client. The client can now initiate key agreement with
5694 another remote client. The key material is passed to the
5695 application after the protocol is over.
5697 * Created client_keyagr.c to include all the key agreement
5700 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5701 SILC_TASK_CALLBACK except that it is not static.
5703 * Created client_notify.c and moved the Notify packet handling
5704 from the client.[ch] into that file.
5706 * Created client_prvmsg.c and moved all private message and
5707 private message key routines from the client.[ch] into that file.
5709 * Create client_channel.c and moved all channel message and
5710 channel private key routines from the client.[ch] into that file.
5712 * Changed silc_client_get_client_by_id_resolve to resolve with
5713 WHOIS command instead of IDENTIFY command, in the file
5714 lib/silclient/idlist.c.
5716 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5718 * Implemented the SKE's responder side to the Client library.
5720 * When FAILURE is received to the protocol do not trust it
5721 blindly. Register a timeout to wait whether the remote closes
5722 the connection as it should do it, only after that process the
5723 actual failure. This was changed to both client and server.
5725 * Added client_internal.h to include some of the structures
5726 there instead of client.h in lib/silcclient/.
5728 * Added function silc_task_unregister_by_callback to unregister
5729 timeouts by the callback function.
5731 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Some "Incomplete WHOIS info" errors has been appearing on the
5734 log files. Took away the entry->userinfo check from WHOIS
5735 reply sending. The entry->userinfo is now " " if client did not
5736 provide one. I thought this was fixed earlier but something
5737 is wrong still. Let's see if the error still appears.
5739 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Fixed a minor bug in the login when the channel key is
5742 re-generated in the server. It used to generate the key in
5743 wrong order and thus caused problems in the channel traffic.
5745 * Fixed a minor bug in channel key distsribution after
5746 KICK command. The key was not sent to the router even though
5749 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added silc_ske_process_key_material_data as generic routine
5752 to process any key material as the SILC protocol dictates. The
5753 function is used by the actual SKE library but can be used by
5754 applications as well. This relates to the private message keys
5755 and the channel private keys since they must be processed the
5756 same way the normal SILC session keys. The protocol dictates
5757 this. Affected files: lib/silcske/silcske.[ch].
5759 Added also silc_ske_free_key_material to free the
5760 SilcSKEKeyMaterial structure.
5762 * Defined silc_cipher_set_key function to set the key for
5763 cipher without using the object's method function. The affected
5764 files: lib/silccrypt/silccipher.[ch].
5766 * Implemented silc silc_client_add_private_message_key,
5767 silc_client_add_private_message_key_ske,
5768 silc_client_del_private_message_key,
5769 silc_client_list_private_message_keys and
5770 silc_client_free_private_message_keys functions in the
5773 Added functions silc_client_send_private_message_key to send
5774 the Private Message Key payload and silc_client_private_message_key
5775 to handle incoming Private Message Key payload.
5777 * Added Cipher field to the Private Message Key payload to set
5778 the cipher to be used. If ignored, the default cipher defined
5779 in the SILC protocol (aes-256-cbc) is used.
5781 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Removed lib/silcclient/ops.h file.
5785 Redefined parts of the SILC Client Library API. Created new
5786 file silcapi.h that deprecates the ops.h file and defines the
5787 published Client Library API. Defined also private message key
5788 API and channel private key API into the file.
5790 This is the file that the application must include from the
5791 SILC Client Library. Other files need not be included by
5792 the application anymore.
5794 * Added new key_agreement client operation callback and also
5795 defined the Key Agreement library API for the application.
5797 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5800 is used by clients to request key negotiation between another
5801 client in the SILC network. If the negotiation is started it
5802 is performed using the SKE protocol. The result of the
5803 negotiation, the secret key material, can be used for example
5804 as private message key.
5806 Implemented the Key Agreement payload into the files
5807 lib/silccore/silauth.[ch].
5809 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Redefined ciphers for the SILC protocol. Added some new ciphers
5812 and defined the key lengths for the algorithms. Changed the
5813 code accordingly. The default key length is now 256 bits.
5815 * Fixed SKE key distribution function silc_ske_process_key_material
5816 when the key length is more than 128 bits. The default key
5817 length in SILC is now 256 bits.
5819 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5820 to indicate unsupported algorithm.
5822 * Renamed rijndael.c to aes.c and all functions as well.
5824 * Fixed a long standing channel key setting bug in client library.
5825 Weird that it has never surfaced before.
5827 * Fixed bug in channel deletion. If the entire channel is removed
5828 then it must also delete the references of the channel entry
5829 from the client's channel list as the client's channel entry and
5830 the channel's client entry share same memory.
5832 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Implemented CONNECT and SHUTDOWN commands in the client.
5836 * Implemented CLOSE command to the client.
5838 * Added the function silc_idlist_find_server_by_name into the
5839 files silcd/idlist.[ch].
5841 Added the function silc_idlist_find_server_by_conn into the
5842 files silcd/idlist.[ch].
5844 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * DIE command was renamed to SHUTDOWN. Updated the both code
5849 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5850 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5852 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5855 * Added function silc_server_create_connection function to create
5856 connection to remote router. My server implementation actually
5857 does not allow router to connect to normal server (it expects
5858 that normal server always initiates the connection to the router)
5859 so the CONNECT command is only good for connecting to another
5862 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5865 or some other client was kicked from the channel.
5867 Implemented the handling of the notify type to both client
5870 Implemented silc_server_send_notify_kicked to send the KICKED
5871 notify. It is used to send it to the server's primary router.
5873 * Implemented the KICK command into server and client.
5875 * Added `query' argument to the silc_idlist_get_client function
5876 to indicate whether to query the client from server or not if
5879 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5880 to indicate that the client is not channel founder.
5884 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Removed the rng context from SilcPacketContext structure and
5887 changed that the packet routine uses the Global RNG API.
5889 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added support for quit message that client can "leave" on the
5892 channel when it quits the SILC. It is ditributed inside the
5893 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5895 Added silc_server_free_client_data that will take the
5896 signoff message as argument.
5898 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5900 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Updated parts of the protocol specification to keep it up
5905 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5908 payloads in one packet.
5910 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5911 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5912 use now the new List flag.
5914 * Also deprecated the following packet types: REPLACE_ID,
5915 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5917 * Added list support for Notify packet in server.
5919 * Added silc_server_send_notify_channel_change to send the
5920 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5921 the silc_server_send_replace_id.
5923 * Added silc_server_send_notify_nick_change to send the
5924 NICK_CHANGE notify type. Deprecates the function
5925 silc_server_send_replace_id.
5927 * Added silc_server_send_notify_join to send the JOIN notify type.
5928 Deprecates the function silc_server_send_new_channel_user.
5930 * Added silc_server_send_notify_leave to send LEAVE notify type.
5931 Deprecates the function silc_server_send_remove_channel_user.
5933 * Added silc_server_send_notify_cmode and
5934 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5935 types. Deprecates the silc_server_send_set_mode function.
5937 * Added SERVER_SIGNOFF notify type to indicate that server has
5938 quit. This means that all clients on the channel from that
5939 server will drop. This can be also used when netsplit happens.
5941 Deprecated REMOVE_ID packet type since it is not needed anymore
5944 Added silc_server_send_notify_server_signoff to send the
5945 SERVER_SIGNOFF notify type. Deprecates the function
5946 silc_server_send_remove_id.
5948 Added also silc_server_send_notify_signoff to send the
5949 SIGNOFF notify type.
5951 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5952 SILC protocol from this day on. Changed the protocol
5953 specification as well.
5955 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5956 notify type. It is used between routers to notify about
5957 topic changes on a channel.
5959 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5962 * Partly updated the protocol specification to comply with the
5963 changes now made. It is still though a bit outdated.
5965 * The JOIN notify type now takes one extra argument <Channel ID>.
5966 The packet used to be destined to the channel but now the
5967 JOIN type may be sent as list thus it is impossible to
5968 destine it to any specific channel. By adding this argument
5969 it is again possible.
5971 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added CREDITS file. The CHANGES and CREDITS file will appear
5974 in the distribution as well.
5976 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5979 types in the server's silcd/packet_receive.c.
5981 * Implemented CMODE and CUMODE to work in router environment.
5983 * Fixed minor encoding and decoding buglet from the
5984 lib/silccore/silcmode.c.
5986 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5989 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5991 * Changed all SilcConfigServer* and silc_config_server* to
5992 SilcServerConfig* and silc_server_config*, respectively.
5995 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Associated the ID (client or server ID) to the Authentication
5998 Payload to avoid any possibility of forging. Updated the
5999 protocol specification and the code accordingly.
6001 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * The RSA key length is now save to the RsaKey context in the
6004 key generation process in lib/silccrypt/rsa.c. The key length
6005 is now used to figure out the maximum size of the block allowed
6006 to be encrypted/signed.
6008 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6009 is equivalent to the silc_mp_mp2bin but does not allocate any
6012 * Changed silc_mp_mp2bin API to take length argument. If it is
6013 non-zero then the buffer is allocated that large. If zero, then
6014 the size is approximated using silc_mp_sizeinbase, which however
6017 * Created Global RNG API which is global RNG that application can
6018 initialize. After initializing, any routine anywhere in the
6019 code (including library) can use RNG without allocating a new
6020 RNG object. This was done to allow this sort of use of the
6021 RNG in code that has no chance to allocate RNG object. All
6022 applications currently allocate this and many routines in the
6023 library use this. Affected file lib/silccrypt/silcrng.[ch].
6025 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6026 it to use the Global RNG API.
6028 * Defined Authentication Payload into protocol specification that
6029 is used during SILC session to authenticate entities. It is
6030 used for example by client to authenticate itself to the server
6031 to obtain server operator privileges.
6033 Implemented this payload into the lib/silccore/silcauth.[ch].
6034 Implemented also routines for public key based authentication
6035 as the new protocol specification dictates.
6037 Moved definitions of different authentication methods from
6038 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6040 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6041 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6042 silc_pkcs_verify_with_hash functions into the file
6043 lib/silccrypt/silcpkcs.[ch].
6045 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * The client entry's userinfo pointer must be always valid.
6048 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6049 will fail since it requires the userinfo. Now, the userinfo
6050 is allocated as "" if actual userinfo does not exist. Actually,
6051 it must exist and it is totally Ok to drop client connections
6052 that does not announce the userinfo. However, we will make
6053 this workaround for now.
6055 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6056 to return the remote port by socket.
6058 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6061 SILC_SERVER_PENDING_EXEC and added an new macro
6062 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6063 data or when error occurs while processing the pending command.
6065 Added new argument `destructor' into silc_server_command_pending
6066 and to the SilcServerCommandPending object. This destructor is
6067 now called after calling the pending callback or if error occurs
6068 immediately. If error occurs the actual pending callback won't
6069 be called at all - only the destructor. The destructor may be
6070 NULL if destructor is not needed.
6072 All this applies for client library code as well. Similar
6073 changes were made there as well for the pending commands.
6075 In the client, the application must now allocate the
6076 SilcClientCommandContext with the silc_client_command_alloc
6079 * Added reference counter to the SilcServerCommandContext. Added
6080 function silc_server_command_alloc and silc_server_command_dup
6083 Same type of functions added to the client library for the same
6086 * Removed the cmd_ident from IDListData away since it is now
6087 global for all connections. It is the command identifier used
6088 in command sending and with pending commands. The affected file
6091 * Added reference counter to the SilcSocketConnection objecet to
6092 indicate the usage count of the object. The object won't be
6093 freed untill the reference counter hits zero. Currently only
6094 server uses this, and client ignores it. The client must be
6095 set to use this too later. The affected files are
6096 lib/silccore/silcsockconn.[ch]. Added also the function
6097 silc_socket_dup to increase the reference counter.
6099 This was mainly added because it is possible that the socket
6100 is removed underneath of pending command or other async
6101 operation. Now it won't be free'd and proper DISCONNECTING
6102 flags, etc. can be set to avoid sending data to connection that
6103 is not valid anymore.
6105 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6106 the connection. After that it sets SILC_SET_DISCONNECTED.
6107 It is, however, possible that the socket data is not still freed.
6108 The silc_server_packet_process now checks that data is not
6109 read or written to connection that is DISCONNECTED. The socket
6110 get's freed when the reference counter hits zero.
6112 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Changed the client operation API: channel_message operation's
6115 `sender' is now the client entry of the sender, not the nickname
6116 and the `channel' is the channel entry, not the channel name.
6118 In the private_message operation the `sender' is now also the
6119 client entry of the sender not the nickname.
6121 Affected file is lib/silcclient/ops.h and all applications
6122 using the client operations.
6124 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Moved the calling of ops->connect() from connect_to_server_final
6127 into receive_new_id functin since that is the point when the
6128 client is actually allowed to send traffic to network. The
6129 affected file is lib/silcclient/client.c.
6131 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6134 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6135 (if needs broadcasting) instead of broadcasting the packets one
6136 by one which would make a burst in the network traffic.
6138 * Added `broadcast' argument to the functions in silcd/server.[ch]
6139 silc_server_create_new_channel[_with_id] to indicate whether
6140 to send New Channel packet to primary router.
6142 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Added new function into the silcd/server.[ch] files:
6145 silc_server_create_new_channel_with_id to create new channel with
6146 already existing Channel ID.
6148 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6149 lib/silccore/silcpacket.h. This packet is used t send list of
6150 Set Mode payloads inside one packet. Server uses this to set
6151 the modes for the channels and clients on those channels, that it
6152 announced to the router when it connected to it. The protocol
6153 specification has been updated accordingly.
6155 * The silc_server_new_channel did not handle the packet coming
6156 from normal server as it normally does not send that. However,
6157 when it announces its channels it does send it. Implemented
6158 the support for that.
6160 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6161 into the file lib/silccore/id.h.
6163 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Fixed memory leaks in the functions silc_idlist_del_client,
6166 silc_idlist_del_channel and silc_idlist_del_server in the file
6167 silcd/idlist.c. All of those leaked like a sieve.
6169 * Fixed some small memory leaks in the client's function
6170 silc_client_notify_by_server.
6172 * Added functions into silcd/server.c: silc_server_announce_clients,
6173 silc_server_announce_channels and silc_server_announce_server.
6174 These functions are used by normal and router server to announce
6175 to its primary router about clients, channels and servers (when
6176 router) that we own. This is done after we've connected to the
6179 These functions effectively implements the following packet types:
6180 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6181 and SILC_PACKET_NEW_ID_LIST.
6183 * Added new functions into the silcd/packet_receive.[ch]:
6184 silc_server_new_id_list, silc_server_new_channel_list and
6185 silc_server_new_channel_user_list to handle the incoming
6186 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6188 * Added support of changing Channel ID in the function
6189 silc_server_replace_id. If the server that announces a channel
6190 to the router already exists in the router (with same name but
6191 with different Channel ID), router is responsible to send
6192 Replace ID packet to the server and force the server to change
6193 the Channel ID to the one router has.
6195 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6196 client that the Channel ID has been changed by the router. The
6197 normal server sends this to the client. Client must start using
6198 the new Channel ID as the channel's ID.
6200 Implemented handling of this new type into lib/silcclient/client.c
6201 into the function silc_client_notify_by_server.
6203 * Added new function silc_idlist_replace_channel_id into the files
6204 silcd/idlist.[ch] to replace the Channel ID.
6206 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Call silc_server_command_identify_check always when processing
6209 the IDENTIFY command in silcd/command.c
6211 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6214 send keepalive packets. The packet can be sent by clients,
6215 servers and routers.
6217 Added function silc_socket_set_heartbeat into the file
6218 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6219 If not set, the heartbeat is not performed. The actual
6220 heartbeat is implemented in the low level socket connection
6221 library. However, application is responsible of actually
6224 Added silc_server_send_heartbeat to send the actual heartbeat
6225 packet into silcd/packet_send.[ch]. Server now performs
6226 keepalive with all connections.
6228 * Added silc_task_get_first function into lib/silcutil/silctask.c
6229 to return the timeout task with shortest timeout. There was a bug
6230 in task unregistration that caused problems. TODO has been
6231 updated to include that task system must be rewritten.
6233 * The client library will now resolve the client information when
6234 receiving JOIN notify from server for client that we know but
6235 have incomplete information.
6237 * Rewrote parts of silc_server_remove_from_channels and
6238 silc_server_remove_from_one_channel as they did not remove the
6239 channel in some circumstances even though they should've.
6241 * Encryption problem encountered in server:
6243 The LEAVE command used to send the Channel Key packet to the
6244 router immediately after generating it. However, the code
6245 had earlier sent Remove Channel user packet but not immediately,
6246 ie. it was put to queue. The order of packets in the router
6247 was that Channel Key packet was first and Remove Channel User
6248 packet was second, even though they were encrypted in the
6249 reverse order. For this reason, MAC check failed. Now, this
6250 is fixed by not sending the Channel Key packet immediately but
6251 putting it to queue. However, this is more fundamental problem:
6252 packets that are in queue should actually not be encrypted
6253 because packets that are sent immediately gets encrypted
6254 actually with wrong IV (and thus MAC check fails). So, packets
6255 that are in queue should be encrypted when they are sent to
6256 the wire and not when they put to the queue.
6258 However, the problem is that the current system has not been
6259 designed to work that way. Instead, the packet is encrypted
6260 as soon as possible and left to the queue. The queue is then
6261 just purged into wire. There won't be any fixes for this
6262 any time soon. So, the current semantic for packet sending
6265 o If you send packet to remote host and do not force the send
6266 (the packet will be in queue) then all subsequent packets to the
6267 same remote host must also be put to the queue. Only after the
6268 queue has been purged is it safe again to force the packet
6271 o If you send all packets immediately then it safe to send
6272 any of subsequent packets through the queue, however, after
6273 the first packet is put to queue then any subsequent packets
6274 must also be put to the queue.
6276 Follow these rules and everything works fine.
6278 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Added new function silc_server_remove_clients_by_server to
6281 remove all client entries from ID list when the server connection
6282 is lost. In this case it is also important to invalidate all
6283 client entires as they hold the invalid server entry. This
6284 fixes fatal bug when server has lost connection and will reconnect
6287 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6289 * Made some sanity checks to silc_server_daemonise like to check
6290 whether the requested user and group actually exists.
6292 * Added sanity check to SKE's silc_ske_responder_finish to check
6293 that the public and private key actually is valid.
6295 * Invalidate the client's nickname when receiving Replace ID
6296 packet and the Client ID is being replaced. This means that the
6297 server will query the nickname if someone needs it (client)
6300 * Sort the ID Cache in client library when the ID Cache data
6301 has changed (needs sorting).
6303 * Do not allow for SILC client to create several connections to
6304 several servers. The client does not support windows right now
6305 and generating multiple connections causes weird behaviour.
6307 Irssi-silc client does support windows and can handle several
6308 connections without problems, see: www.irssi.org and SILC plugin.
6310 * Fixed some places where client was added to the IDList. The
6311 rule of thumb is following (in order to get everything right):
6312 If the client is directly connected local client then the
6313 `connection' argument must be set and `router' argument must be
6314 NULL to silc_idlist_add_client function. If the client is not
6315 directly connected client then the `router' argument must
6316 bet set and the `connection' argument must be NULL to the
6317 silc_idlist_add_client function.
6319 * The funtion silc_server_packet_send_local_channel actually did
6320 not check whether the client was locally connected or not. It
6321 does that now. Fixed a bug related to LEAVE command.
6323 * Fixed Remove Channel User payload parsing bug in server's
6324 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6326 * The server's silc_server_save_channel_key now checks also the
6327 global ID list for the channel as it might not be in the local
6328 list. Fixed a bug related to LEAVE command.
6330 * Is this the end of the [<unknown>] buglet that has been lurking
6331 around for a long time? A little for loop fix in server's
6332 silc_server_command_whois_parse that is used by both IDENTIFY
6333 and WHOIS command. At least, this was a clear bug and a cause
6334 of one type of [<unknown>] buglet.
6336 * WHOIS and IDENTIFY commands call the function
6337 silc_server_command_[whois/identify]_check function even if
6338 we are not router server.
6340 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Added --with-gmp configuration option. If set the GMP
6343 is always compiled in the SILC source tree. If not set then
6344 it is checked whether the system has the GMP3 installed. If
6345 it has then the GMP won't be compiled (the system's headers
6346 and library is used), if it doesn't have it then the GMP is
6347 compiled in the SILC source tree.
6349 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6351 * Changed RSA private exponent generation to what PKCS #1
6352 suggests. We try to find the smallest possible d by doing
6353 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6354 not security fix but optimization.
6356 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Added new config entry [Identity] to fork the server and run
6359 it as specific user and group. A patch from Bostik.
6361 * Imported Dotconf configuration library into lib/dotconf.
6362 This will be used to create the SILC configuration files later.
6363 It will appear in the distsribution after this commit.
6365 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * A big code auditing weekend happening. Auditing code for
6368 obvious mistakes, bugs and errors. Also, removing any code
6371 Removed files for being obsolete:
6373 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6374 inline in the file lib/silcutil/silcbuffer.h)
6376 o lib/silcutil/silcbufutil.c (the header has inline versions)
6378 Changed code to fix possible error conditions:
6380 o The buffer formatting routines now check that the destination
6381 buffer really has enough space to add the data. This applies for
6382 both buffer formatting and unformatting
6383 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6384 unformatting was changed to accomodate following rules:
6385 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6386 sent to the function while XXX_*STRING will not allocate or copy
6387 the data into the buffer. Instead it sets the pointer from the
6388 buffer into the pointer sent as argument (XXX_*STRING used to
6389 require that the pointer must be allocated already). This change
6390 makes this whole thing a bit more consistent and more optimized
6391 (note that the data returned in the unformatting with XXX_*STRING
6392 must not be freed now). The routines return now -1 on error.
6394 o Tried to find all code that use buffer_format and buffer_unformat
6395 and added return value checking to prevent formatting and
6396 especially unformatting errors and possible subsequent fatal
6399 o Changed ske->x and ske->KEY to mallocated pointers in
6400 lib/silcske/silcske.h. Fixed possible data and memory leak.
6402 o Added return value checking to all *_parse* functions. Fixed
6403 many memory leaks as well.
6405 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6406 so that buffer overflows would not happen. All code now also
6407 checks the return value as it can fail.
6409 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Added reconnection support to server if the normal server looses
6412 its connection to the router (for example if router is rebooted).
6413 The server performs normal reconnection strategy implemented
6414 to the server. Affected file silcd/server.c.
6416 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6418 * Added new packet type SILC_PACKET_SET_MODE that is used to
6419 distribute the information about changed modes (for clients,
6420 channels and clients channel modes) to all routers in the
6421 network. Updated the protocol specification accordingly.
6423 Added functions into silcd/packet_send.c and
6424 silcd/packet_receive.c: silc_server_send_set_mode,
6425 silc_server_set_mode.
6427 Added new files silcmode.[ch] into lib/silccore that implements
6428 the encoding and decoding of Set Mode Payload. Added new type
6429 SilcSetModePayload. Moved the definitions of different modes
6430 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6432 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Oops, a little mistake in server's connection authentication
6435 protocol. The protocol is not ended with FAILURE but with
6436 SUCCESS if the authentication is Ok. :) Affected file is
6439 * Implemented NICK_CHANGE notify handling in server in the file
6440 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6441 the local clients on the channel. After the changing nickname
6442 in router environment snhould work and the [<unknown>] nickname
6443 should appear no more.
6445 The silc_server_replace_id function that receives the Replace ID
6446 payload now sends the NICK_CHANGE notify type also in the file
6447 silcd/packet_receive.c
6449 * Changed WHOIS and IDENTIFY command to support the maximum amount
6450 of arguments defined in protocol specs (3328 arguments). This
6451 fixed a bug that caused problems when there were more than three
6454 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Added extra parameter, command identifier, to the
6457 silc_client_send_command so that explicit command identifier
6460 Changed that ID list routines uses specific command identifier
6461 when sending WHOIS/IDENTIFY requests to the server so that they
6462 can be identified when the reply comes back.
6464 Affected files lib/silcclient/command.[ch],
6465 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6467 * Added `sender' argument to silc_server_packet_send_to_channel
6468 to indicaet the sender who originally sent the packet to us
6469 that we are now re-sending. Ignored if NULL. Affected file
6470 silcd/packet_send.[ch].
6472 * Added some server statistics support in silcd/server_internal.h
6473 SilcServerStatistics structure and around the server code. Also
6474 send some nice statistics information when client is connecting
6477 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Fixed channel ID decoding in server's JOIN command reply in
6480 silcd/command_reply.c
6482 * Fixed braodcasting of replace ID payload to not to send it if
6483 we are standalone server in silcd/packet_receive.c.
6485 * Fixed all channel message sending routines to not to send
6486 packets to clients that has router set, since they are routed
6487 separately in the same function earlier. Affects file
6488 silcd/packet_send.c and all channel packet sending functions.
6490 * In USERS reply, res_argv[i] are not allocated, the table
6491 is allocated. Thus changed that free the table, not its
6494 * In server's whois_check and identify_check if the client is
6495 locally connected do not send any WHOIS commands - they are not
6498 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6500 * Fixed some minor bugs in client when sending WHOIS command. The
6501 arguments was in wrong order.
6503 * Removed statis function add_to_channel from server in
6504 silcd/command.c that was previously used with the joining but
6507 * Tested USERS command in router environment successfully with two
6508 routers, two servers and two clients.
6510 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Reorganized the USERS command and command reply in client library
6513 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6514 When the command is given by user we register a pending command
6515 callback that will reprocess the command after the reply has been
6516 received from the server. When reprocessing the packet we then
6517 display the information. Thus, the USERS information is displayed
6518 now in the command callback instead of in the command reply
6519 callback. The processing of the command is same as previously
6520 when server has sent the command reply in the JOINing process.
6522 * Added to USERS command in silcd/command_reply.c to join the client,
6523 we didn't use to know about, to the channel after we've created
6524 a client entry for it. Also, for clienet we did know already still
6525 check whether it is on the channel or not and add it if not.
6527 * Removed silc_server_command_join_notify as the function and its
6530 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Changed the client's pending command handling to the same as the
6533 server's pending command handling. It is also now possible to
6534 execute command reply functions from other command reply
6535 function as the function callbacks for commands and command
6536 replies are one and same. The pending commands are not static
6537 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6538 in client connection context. Thus, pending commands are server
6539 connection specific as it is convenient.
6541 Changed the function silc_client_command_pending and
6542 silc_client_command_pending_del and added new function
6543 silc_client_command_pending_check. Removed the
6544 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6547 * Added cmd_ident, current command identifier, to the client
6548 connection context in lib/silcclient/client.h to keep track on
6549 command identifiers used in command sending. Client's command reply
6550 function handling now supports the mandatory command identifiers.
6552 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6553 funtions in client to fully support pending command callbacks.
6555 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6556 as one of the arguments to the application in the command reply
6559 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6560 before first releasing SILC but came back. Now it is removed again
6561 and should come back nomore. The FORWARDED flag was used only
6562 by the JOINing procedure by forwarding the command packet to router.
6563 Now, the JOINing procedure has been changed to more generic (due
6564 to various router environment issues) and FORWARDED is not needed
6565 anymore for anything. The protocol specification is yet to be
6568 Now, removed silc_server_packet_forward from server and the flag
6569 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6571 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Renamed NAMES command to USERS command. The NAMES was named that
6574 due to historical reasons. Now it is renamed. Also, rewrote
6575 parts of the USERS command. The nickname list is not sent anymore
6576 by the server. Only Client ID and mode lists are sent in the USERS
6577 command. Changed this also to the protocol specification.
6579 The client now resolves the names and stuff after it receives
6580 the USERS list from the server when joining to the channel.
6582 * WHOIS and IDENTIFY commands has been changed to support multiple
6583 Client ID's per command. One can now search for multiple users
6584 in the network by sending only one WHOIS or IDENTIFY command.
6585 Changed the code and the protocol specifications.
6587 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6588 uses silc_server_command_whois_parse to parse the request. */
6590 * If normal server, do not parse the WHOIS and IDENTIFY requests
6591 before sending it to the router. Saves some time.
6593 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Fixed JOIN command on client library. Wrong number of arguments
6596 used to crash the client.
6598 * Added silc_server_channel_has_global function to check whether
6599 channel has global users or not.
6601 * Added silc_server_channel_has_local function to check whether channel
6602 has locally connected clients on the channel.
6604 * The silc_server_remove_from_one_channel now checks whether the
6605 channel has global users or not after given client was removed from
6606 the channel. It also checks whether the channel has local clients
6607 on the channel anymore. If it does not have then the channel entry
6608 is removed as it is not needed anymore.
6610 * The silc_server_notify now checks on JOIN notify whether the joining
6611 client is one of locally connected or global. If it is global then
6612 the channel has now global users on the channel and that is marked
6613 to the channel entry. Also, it now saves the global client to
6614 global list who is joining and JOINs it to the channel. This is
6615 for normal server, that is.
6617 Changed silc_server_send_notify_on_channel,
6618 silc_server_packet_relay_to_channel and
6619 silc_server_packet_send_to_channel check if we are normal server
6620 and client has router set (ie. global client) do not send the
6621 message to that client, as it is already routed to our router.
6623 * Implemented LEAVE notify type handling in silc_server_notify
6626 * Tested LEAVE command in router environment successfully. Tested
6627 with two routers, two servers and two clients.
6631 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6633 * Implemented SIGNOFF notify type handling in silc_server_notify
6636 * silc_server_remove_id now removes the client entry from all channels
6637 it has joined and thusly sends SIGNOFF notify type.
6639 * Rewrote the NAMES list generation in server by removing two excess
6640 loops. The lists are created now inside one loop.
6642 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6644 * silc_server_remove_channel_user checks now also global list
6645 for channel and client.
6647 * silc_server_new_channel_user checks now both local and global
6648 list for channel and client. Fixed a bug in client id decoding.
6649 Used to decode wrong buffer.
6651 * silc_server_channel_message checks now both local and global
6652 list for channel entry.
6654 * Tested channel joining (hence JOIN) in router environment
6655 successfully. Tested with two routers, two servers and two
6658 * Tested channel message sending in router environment successfully.
6660 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Added silc_server_save_channel_key into server.[ch] to save the
6663 received channel key in Channel Key payload processing. It is
6664 also used in JOIN command reply handling.
6666 Equivalent function silc_client_save_channel_key added into
6667 client.[ch] into client library.
6669 * Changed JOIN command reply to send information whether the channel
6670 was created or not (is existing already) and the channel key
6671 payload. Changed protocol specs accordingly.
6673 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6674 the request was sent by ID and not by nickname. Crashed on
6677 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6680 now correctly save the received data.
6682 * silc_server_free_sock_user_data now notifies routers in the
6683 network about entities leaving the network.
6685 At the same time implemented functions silc_server_remove_id
6686 and silc_server_send_remove_id to receive and send REMOVE_ID
6687 packets. The packet is used to notify routers in the network
6688 about leaving entities. The ID removed will become invalid in
6691 * Added function silc_idlist_del_server into server. Removes and
6692 free's server entry from ID list.
6694 * silc_server_private_message function now checks, if we are router,
6695 that the destination ID really is valid ID, naturally.
6697 * In router when NEW_ID packet is received (for new client) the
6698 hash of the Client ID is saved in the ID Cache but the
6699 client->nickname is set to NULL, instead of putting the hash
6702 IDENTIFY command now also checks that client->nickname must be
6703 valid. If it is not if will request the data from the server who
6704 owns the client. Added new function
6705 silc_server_command_identify_check.
6707 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6708 to set the command to already allocated Command Payload.
6710 * Tested private message sending in router environment with two
6711 routers, two servers and two clients. Fixed minor bugs and now
6714 * Fixed segfault from client's NAMES command. Used to crash if
6717 * Forwarded packets must not be routed even if it is not destined
6718 to the receiver. Changed server code comply with this.
6720 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6722 * Added `require_reverse_mapping' boolean value to ServerParams
6723 structure. If TRUE (not default) the server will require that
6724 the connecting host has fully qualified domain name.
6726 If the reverse mapping is not required and hostname could not be
6727 found the IP address is used as hostname.
6729 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Implemented version string checking to both client and server.
6732 The check is incomplete currently due to the abnormal version
6733 strings used in development version of SILC.
6735 * Changed all command functions in server to use the new
6738 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * Changed char *data to unsigned char *data in ID Cache system to
6741 support binary data as ID Cache data. Changed code to support
6742 binary data in lib/silccore/idcache.c.
6744 * Renamed silc_server_packet_relay_command_reply to
6745 silc_server_command_reply as it is normal packet receiving
6746 function. Rewrote the function to accept command replys for
6747 servers and not only for clients.
6749 * Mark remote router always as registered server if we are connecting
6750 to it. Otherwise, commands sent by the router to us are ignored.
6752 * All ID List find routines now returns the ID Cache Entry pointer
6753 as well if requested.
6755 * WHOIS command works now in router environment, tested with two
6756 routers, two servers and two clients.
6758 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6759 in router environment (as it is almost equivalent to WHOIS) but
6760 hasn't been tested thoroughly. Added new functions:
6762 silc_server_command_identify_parse
6763 silc_server_command_identify_send_reply
6764 silc_server_command_identify_from_client
6765 silc_server_command_identify_from_server
6767 * Disabled route cache adding because adding two different ID's with
6768 same IP replaces the old cache entry thus giving wrong route.
6769 The entry->router->connection is always the fastest route anyway
6770 so route cache may not be needed. Of course, new routes maybe
6771 established after receiving the ID when the entry->router->connection
6772 might not be anymore the most optimal.
6774 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Add route cache for received ID for fast routing.
6778 * Added silc_server_packet_route to route received packet on router
6779 that is not destined to us.
6781 * Renamed silc_server_get_route to silc_server_route_get.
6783 * Added id_string and id_string_len fields into SilcServer to
6784 include encoded ServerID for fast comparing without excess
6785 encoding of the ID's.
6787 * Cleaned up WHOIS command on server side. Added following static
6790 silc_server_command_whois_parse
6791 silc_server_command_whois_check
6792 silc_server_command_whois_send_reply
6793 silc_server_command_whois_from_client
6794 silc_server_command_whois_from_server
6796 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6797 arguments in command replies. All command functions should be
6798 updated to use this macro.
6800 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Minor typo fixes on command reply handling on server.
6804 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Added silc_server_command_add_to_channel internal routine to add
6807 the client to the channel after router has created the channel and
6808 sent command reply to the server.
6810 * Added generic silc_server_send_command to send any command from
6813 * Use static buffer with ID rendering instead of duplicating data.
6815 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Fixed a channel user mode bug when joining to a channel server gave
6818 everybody channel founder rights, oops.
6820 * We mark ourselves as the router of the incoming server connection
6821 if we are router ourselves. This way we can check in some packet
6822 sending functions whether it is locally connected server. For
6823 incoming router connections we put NULL.
6825 * For router sending packets locally means now always sending the
6826 packet cell wide; to local clients and local servers. For normal
6827 server sending packet locally means sending it to only local
6830 * Fixed the JOIN command to really work in router environment. If the
6831 channel is created it is always created by the router. Router is
6832 also responsible of making the initial joining to the channel,
6833 sending JOIN notify to the sending server and distributing
6834 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6835 does not exist server doesn't do anything else but forward the
6836 command to the router which performs everything.
6838 * Added silc_server_send_channel_key function to send the Channel Key
6841 * Added silc_server_create_channel_key to create new channel key. The
6842 channel key is now re-generated everytime someone joins or leaves
6843 a channel, as protocol dictates. Note: channel->key_len is the
6846 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6849 packet_receive.[ch] to separate packet sending and receiving
6850 routines. The server.[ch] now includes everything else including
6851 actual packet processing (writing and reading data) and other
6854 Renamed silc_server_private_message_send_internal to
6855 silc_server_send_private_message. The routine is still though
6856 used only to relay private messages as server does not send
6857 private messages itself.
6859 Renamed silc_server_new_channel to silc_server_create_new_channel
6860 and added new function sicl_server_new_channel that handles the
6861 incoming New Channel packet. Added also new sending function
6862 silc_server_send_new_channel to send New Channel Payload.
6864 * Added new function silc_server_notify to process incoming notify
6865 packet to the server/router. Server may then relay the notify
6866 to clients if needed.
6868 * Added new function silc_server_new_channel_user to process incoming
6869 New Channel User packet. Router will redistribute the packet and
6870 send JOIN notify to its local clients and locally connected servers
6871 if needed. Normal server will send JOIN notify to its local client
6872 on same channel when received this packet. Added also corresponding
6873 sending function silc_server_send_new_channel_user to sent the
6876 * Added boolean route argument to send_notif_to_channel and
6877 packet_send_to_channel functions to attempt to route the packet
6878 if it is TRUE and send only locally if it is FALSE.
6880 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * silc_server_replace_id now broadcasts the received replace ID
6883 packet if it is not broadcast packet already. The router must
6884 broadcast to inform other routers about changed ID.
6886 * Added backpointer to server's router into SilcServer context in
6887 silcd/server_internal.h.
6889 * Fixed silc_server_packet_broadcast to send correct broadcast
6892 * The channel key is now distributed to the local client as soon
6893 as it is received from the router (in router environment) so that
6894 no other packet may be sent for the channel until client has
6897 * silc_server_remove_channel_user now broadcasts the received
6898 Remove Channel User packet if it is not broadcast packet already.
6899 The router must broadcast to inform other routers about removed
6902 * Added users field into SilcPacketContext that is a reference count
6903 of the context. One can increase the reference count by calling
6904 silc_packet_context_dup which is now changed to just increase the
6905 reference count instead of duplicating the data. The reference
6906 count is decresed by calling silc_packet_context_free that will
6907 free the data after the reference count hits zero.
6909 For now on the packet context and everything allocated into it
6910 (including the raw packet from network) must be freed by calling
6911 the new silc_packet_context_free function. Added also new function
6912 silc_packet_context_alloc that must be used now to allocate the
6913 context. This also means that if a routine is asynchronous from
6914 silc_[client/server]_packet_parse_type the packet context must
6915 be duplicated by calling silc_packet_context_dup. Otherwise it
6916 gets free'd after silc_[client/server]_packet_parse_type returns.
6917 Also, one must remember that if packet is duplicated then its
6918 reference count must be decresed by calling the free function as
6919 many times as it was duplicated.
6921 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6922 from both client and server.
6924 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Made joining to a channel working in router environment.
6928 * Cleaned up JOIN command on server side and create function
6929 silc_server_command_join_channel internal routine to make the
6932 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Changed silc_command_pending list to SilcDList. Also, added
6935 `ident' field to SilcServerCommandPending structure to identify
6936 the reply and to call correct callback.
6938 Added silc_server_command_pending_check function to replace the
6939 corresnponding macro. The silc_command_pending list is not
6942 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6943 to set identifier to previously allocated Command Payload. It
6944 is used to set identifier for command when resending Command
6947 * Added silc_command_payload_encode_payload to encode Command
6948 Payload buffer from SilcCommandPayload structure.
6950 * Added silc_argument_payload_encode_payload to encode Argument
6951 payload buffer from SilcArgumentPayload structure.
6953 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Changed WHOIS command to support router connection on server side.
6956 The whois request is always sent to router unless the server is
6957 standalone server. After server has received the reply from the
6958 router will it send the reply to the client.
6960 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6961 broadcast received broadcast packet. The function is used only
6962 by router. The broadcast packet is always sent to the router's
6965 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6966 render given ID to printable string, for log files for example.
6968 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Made basic router to router connections working. At least they
6971 can now connect to each other but nothing really works the way
6972 they are supposed - yet.
6974 * Added new initiator token to RouterConnection configuration
6975 file in silcd/serverconfig.[ch]. It is used to tell whether we
6976 are the initiator to the remote router or whether we'll expect
6977 the other end to connect.
6979 * Moved registering of listener task to silc_server_init, hence
6980 the server starts listenning as soon as it is run, even if it
6981 does not have connections to other routers. Let's see how well
6984 * Changed default connection retry timeouts for more suitable in
6987 * Removed cipher and such arguments from silc_idlist_add_client
6988 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6989 Added new function silc_idlist_add_data to add the keys and stuff
6992 * Added SilcIDListData structure and added it to SilcClientEntry
6993 and SilcServerEntry as their first field in the structure. This
6994 way we can explicitly cast the ID entries to the SilcIDListData
6995 structure and get common data for the entries. In past, we had
6996 to first check what type of connection it is and then cast it to
6997 correct ID entry type. Now, we can directly cast the opaque
6998 pointer to the SilcIDListData (no matter what ID entry it actually
6999 is) and get the data needed.
7001 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7004 in some circumstances even if threre were timeout tasks, though not
7005 IO tasks, but tasks anyway. Now fixed.
7007 * Defined SilcServerConnection structure to hold connection specific
7008 stuff about directly connected servers and routers. The definition
7009 is currently in silcd/server_internal.h. I thought about having
7010 a bit more important role fro this struct but for now it is used
7011 only when connecting to other server (or router actually).
7013 * Added connecting retry support in server when connecting to
7014 router(s). The retry feature implement exponential backoff
7015 algorithm. Also, added SilcServerParams structure to hold default
7016 parameters for server. For now, it include these retry settings
7017 and are hard coded. After server is moded to be as Silc Server
7018 Library this structure will be more important.
7020 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Changed client librarys channel->clients table to SilcList and
7023 changed code accordingly.
7025 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Changed client's channel table to SilcList and changed code
7028 accordingly. Also changed SilcChannelClientEntry to include back-
7029 pointer to the channel so that client entry can use that structure
7030 as list as well and we have fast cross-reference to the channel.
7031 This change dramatically decreased the complexity of channel
7032 handling with client entry and vice versa (removed one extra
7033 loop when searching for channel entry from many functions).
7035 * Changed server->sim from table to SilcDList and changed code
7038 * NAMES command can now be used from user interface. It will show
7039 the user list on the channel, neatly.
7041 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7042 Code now saves realname of the user if it becomes available.
7044 * Renamed configure.in to configure.in.pre and made ./prepare
7045 script to automatically add correct version string to
7046 configure.in which it creates from configure.in.pre.
7048 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * NAMES command reply now shows users mode with the nickname when
7053 * Moved silc_client_ch[u]mode[_char] functions from
7054 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7055 place sucks, they are utility functions and should be in some
7058 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7060 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7063 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Added TRQ (efficient deque and list library) into lib/trq. This is
7068 a very good list library that is currently used in the SILC. Defined
7069 SilcList API over the library because I didn't like the API very
7070 much. See lib/trq/silclist.h for the API and examples of how to
7071 use the API. Fixed various places in the code to use the new
7072 SilcList API. The SilcList is meant for lists that has a structure
7073 already defined as a list. It is not suitable to add just some
7074 context to the list (in TRQ, the context is the list actually).
7076 So, I defined SilcDList that can be used for the purpose where
7077 predefined list structure does not exit. This can be used as
7078 such list. Now some context just can be added to the SilcDList.
7079 Currently this list is not used in the SILC just yet, though there
7080 are a lot places where this can replace dynamically allocated
7081 tables and I will fix these places, later, to use SilcDList.
7082 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7083 and use TRQ internally).
7085 Also fixed some annoying warning messages that the original TRQ
7086 code generated. Also minor changes to TRQ's Makefile.in.
7088 * Added support for querying by Client ID to both WHOIS and
7089 IDENTIFY commands into server, as required by the protocol.
7091 * Removed method function pointers from SilcBuffer structure. They
7092 weren't used to anything and just increased the context size for
7093 no good reason. This change also made silc_buffer_alloc and
7094 silc_buffer_free functions inline functions.
7096 * Disabled command flooding detection support until it's fixed so
7097 that it accepts commands in but does not execute them more than once
7100 * Added silc_net_localhost(), to return local hostname, into
7101 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7102 that must be initialized before calling silc_client_init.
7104 * Added new function: silc_server_send_notify_on_channels to send
7105 notify messages to all channels client has joined. It is assured
7106 that the message is sent only once per client.
7108 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7109 lib/silcutil/silcutil.[ch] as silc_format function. The new
7110 function is generic and is used by server as well, not only by
7111 the logging routines.
7113 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7114 the provided version string was not acceptable. Added new function:
7115 silc_ske_check_version into lib/silcske/silcske.h. The function
7116 must be implemented by the application (client or server) and it
7117 does not reside in the SKE library. The function checks the version
7118 string remote end sent.
7120 * Added back pointers (to opaque context and to SilcSocketConnection)
7121 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7123 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7124 duplicate packet context structure.
7126 * Changed `notify' client operation to send same arguments as client
7127 receives from server except for ID's. ID's are mapped to correct
7128 ID entry and that is returned. Also, if channel entry is not sent
7129 by server but the notify is for channel the channel entry is sent
7130 to application (otherwise application doesn't know that it is for
7131 channel (library gets it from packet's Destination ID)).
7133 * Added silc_client_remove_from_channels into client library to
7134 remove a client from all channels it has joined to. Used when
7135 received SIGNOFF notify from server. Added also new function
7136 silc_client_replace_from_channels to replace old ID entry with
7137 new ID entry on all channels. Used when received NICK_CHANGE
7140 * Fixed ID Cache list handling in silc_idlist_get_client in
7141 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7142 to get (or query) client by ID.
7144 * Updated TODO list.
7146 * Added connection authentication status message defined by the
7147 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7148 support for these into the code in client and server side.
7150 * Added generic function silc_client_send_command to send any command
7151 with variable argument list. Application should use this function
7152 to send commands if the command functions provided by the library
7153 does not suite for the application's user interface needs.
7155 * Added new `failure' client operation. Application is notified about
7156 received failure packet if client is executing a protocol. In this
7157 case the protocol's execution has failed.
7159 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7160 is required by the protocol.
7162 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7163 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7166 * Added status flag to SilcSKE object to indicate realtime status
7167 of the SKE protocol.
7169 * Application receives now exactly same command reply arguments as
7170 the library receives from server. However, if ID is received the
7171 corresponding ID entry is returned to the application (eg. Client
7172 ID is mapped to correct SilcClientEntry entry and that is returned).
7173 Changed command_reply client operation due to this change.
7175 * Changed all ID's in commands and in command replys as ID Payloads.
7176 Change affected both client and server side codes.
7178 All ID's sent in SILC network (with execption of ID's in SILC
7179 Packet header) are sent in ID Payload to support variable length
7182 * Server now notifies nick changes and notifies all clients on
7183 the channels about the new nickname (about the new Client ID,
7186 * Implemented CMODE command to change channel modes. Supports all
7187 channel modes defined by the protocol specs except ban and invite
7188 lists. (Also, private channel key mode is supported but support for
7189 setting private channel key in client is missing, thus, this mode
7190 has no effect on client side (except that server requires that the
7191 client uses private channel key and normal channel traffic does not
7194 Also, invite mode works per se, but INVITE command does not work
7195 yet correctly, so you can set channel as invite only channel but
7196 inviting clients to the channel does not work (it is yet to be
7197 thought what's the best way to do it).
7199 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7200 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7201 Implemented CUMODE command to change user's mode on the channel.
7202 Supports all modes defined by the protocol specs.
7204 * Added NAMES command reply to return users modes on the channel.
7206 * Removed unnecessary and slow ciphers from lib/silccrypt.
7208 * Set SO_KEEPALIVE option to connection sockets by default.
7210 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7212 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7213 redefined the Notify Payload into protocol specs.
7215 * Added silc_id_payload_parse_id to get ID directly from raw
7218 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7221 accept searching by Client ID as well.
7223 * Added support for LEAVE and SIGNOFF notify types in client library.
7225 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7226 to parse ID Payload from raw data.
7228 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Added flags parameter into silc_ske_assemble_security_properties
7231 function in lib/silcske/silcske.[ch].
7233 * Changed notify client operation to fit better for notify messages
7234 sent by server. The notify payload received from server is now
7235 passed to the application (after parsing it to SilcNotifyPayload).
7236 It is application's responsibility to retrieve the arguments
7237 from the payload and show the message the way it wants. The message
7238 sent by server is implementation specific.
7240 * Changed public keys to comply with the protocol specification.
7241 Old public keys are not supported anymore and are not compatible.
7243 * Removed nickname from Channel Payload as the latest draft removed
7244 it. The client must resolve the nickname from the NAMES command
7245 reply received when it joined the channel.
7247 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7249 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7251 * Fixed some errors in protocol specification drafts.
7253 * Created lib/silccore/silcnotify.c to implement Notify Payload
7254 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7255 generic payloads described by protocol specifications. The file
7256 includes implementations for ID Payload and Argument Payload.
7258 * Changed Command Payload implementation to use the new Argument
7259 Payload. Changed command_xxxx_payload to command_payload_xxxx
7260 to comply with SILC coding conventions.
7262 * Added suppport for Argument Payload handling in Notify Payload
7263 implementation as protocol requires it. Added the new support
7264 into server and client lib as well.
7266 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added support for multiple nicknames on same channel. [n] is
7269 added locally to the nickname if there are more than one same
7270 nicknames on the channel.
7272 * Server now sends all nicknames that matched WHOIS request.
7273 Client also shows the list received from server.
7275 * Added TOPIC command to client side. User can now set and show
7276 current topic on channel.
7278 * Added MOTD command to client and server. Also, server sends the
7279 motd when client connects to the server.
7281 * Changed version strings to comply ISO 8601.
7283 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Fixed protocol error handling in client library. It should now
7286 cope even if the SKE fails for some reason.
7288 * Made new protocol specification drafts for submitting to IETF.
7290 * Implemented TOPIC command to server in silcd/command.c.
7292 * Added two new notify types into lib/silccore/silcnotify.h:
7293 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7294 notify nickname change and topic setting/change on a channel.
7296 * API change of command_reply operation in client library. The
7297 application gets now the status type received from server as well.
7299 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7303 * Cras fixed and optimized the packet handling even further and
7304 it should work now. Minor change to the prototype of function
7305 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7307 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Added new function into lib/silcutil/silcschedule.[ch]:
7310 silc_schedule_with_fd to select() a specified fd. The function
7311 returns after timeout expires or data arrives or goes. The
7312 function is used by packet routines to wait that all data is
7313 received from network.
7315 * Fixed data reading from network in lib/silccore/silcpacket.c.
7316 The code now assures that all data is read from the fd and then
7317 continues packet processing. This was a bug fix since the code
7318 used to drop some data in some circumstances.
7320 * Added new function into lib/silcclient/client.[ch]:
7321 silc_client_start_key_exchange to start key exchange after
7322 connection has been established to server. The code internally
7323 now uses this funtion but its main purpose was to provide it
7324 for applications that perform their own connecting. After
7325 application has created a connection it merely calls this
7326 function to start the key exchange between client and server.
7327 The library takes care of everything else after that.
7329 Updated also lib/silcclient/README to explain the usage of
7332 * Do not send to application information that connection has
7333 been established. Application gets notified it by connect
7336 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Applied cras's patch to add silc_schedule_one function. The
7339 function runs scheduler once and returns.
7341 * Fixed the scheduler after cras messed it up. The timeout
7342 handling works now as it's supposed to work.
7344 * Added into lib/silccore/ silcnotify.h to include notify
7345 message types support. Changed silc_server_send_notify*
7346 functions, in server.[ch], to support those new notify types.
7347 Added the support for the notify types into client library,
7348 as well. Added new notify client operation into ops.h in
7351 * Changed silc_server_packet_send_to_channel to send normal
7352 packets instead of just channel message packets. The function
7353 is now used to send the notify packets to channels. It is not
7354 used to send channel message packets anymore, as server never
7357 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7358 va_arg()s as it seems to require it nowadays. I guess, if SILC
7359 is compiled with older va_arg() the new code should work anyway.
7361 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Splitted core library. Core library (lib/silccore) includes
7364 now only SILC protocol specific core (and common) components.
7365 Created new utility library (lib/silcutil) that includes more
7366 generic purpose stuff. The stuff for util library was taken
7367 from the old core library. This was minor and easy split.
7369 * Created SILC Client Library (lib/silcclient) that includes
7370 implementation of the SILC client without user interface. This
7371 was major move from silc/ directory. The code has been changed
7372 so that it is transparent towards the user interface. The
7373 silc/ directory includes now the same user interface as before
7374 and it uses the new client library. Read lib/silcclient/README.
7375 Basicly, the client library performs everything else related
7376 to SILC except user interface handling. Also, configuration
7377 files are considered to be part of user interface and library
7378 does not handle them.
7380 This change also changed a lot of structures, function naming etc.
7381 Most important change was that SilcClientWindow object was
7382 renamed to SilcClientConnection in the client library. Created
7383 also new file lib/silcclient/ops.h. Also added new files
7384 silc/local_command.[ch] and silc/client_ops.[ch].
7386 All these changes were made to make it easier for user interface
7387 designers to create what ever user interface for the SILC client
7390 It is also expected that the server will be moved to lib
7391 directory as well and SILC Server Library will be created;
7392 sometimes in the future.
7394 * Removed Local commands from lib/silccore/silccommand.h as
7395 they are application specific and new client library does not
7396 handle any of those anymore.
7398 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7399 old client implementation in silc/.
7401 * Added support for callback functions in SILC_LOG_* macros.
7402 Application can now set its own callbacks that will be called
7403 instead of using the default functions that will always print
7404 the debug messages to stderr (or stdout). Also, debugging can
7405 now be disabled by setting silc_debug to FALSE and re-enabled by
7406 setting it to TRUE. Note, that logging will still work even
7407 if debugging is disabled.
7409 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7410 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7411 silc_log_reset_debug_callbacks.
7413 * To enable debugging in silc client one must give now -d
7414 option on command line.
7416 * Changed silc_schedule_init to automatically allocate task queues
7417 if they are not allocated before calling it.
7419 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Added GMP 3.1 into math library.
7423 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7426 a channel in SILC network. The packet is used by servers and
7427 routers to notify other routers that user has left a channel.
7428 This little feature was missing until now. Added the feature
7429 to protocol specification as well.
7431 Added functions: silc_server_send_remove_channel_user and
7432 silc_server_remove_channel_user into server.[ch].
7434 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7435 lib/silccore/silcpacket.h. However, they are not implemented
7438 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7440 * Fixed joining to a channel and sending channel messages
7441 between server and router. The channel message sending should
7442 now work inside a cell.
7444 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7446 * Fixed the private message sending between server and router.
7447 The private message sending should now work inside a cell.
7449 * Added silc_server_replace_id into server.[ch] to replace
7450 existing ID in the SILC network.
7452 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7453 and silc_idlist_replace_server_id into idlist.[ch] in server.
7455 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Fixed the server to server connections. Server can again now
7458 connect to router. Router to router connections probably does
7461 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7463 * Added dynamic protocol registering support. Now protocols can
7464 registered and unregistered on the fly. Patch by cras.
7466 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Added lib/contrib directory to hold routines that some platforms
7469 don't have but are needed by SILC.
7471 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7472 into lin/contrib to provide getopt() and getopt_long() for
7473 those who don't have it.
7475 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Added AWAY command to client. When away message is set and
7478 client receives a private message packet the client automatically
7479 replies to the sender with the away message.
7481 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7482 bug seemed to be the cause of recent problems when compiling
7485 * Added version detection support to SKE protocol specification
7486 and added the new changes to the SKE implementation as well.
7487 There were other minor changes in the SKE protocol as well.
7489 Many changes in lib/silcske/silcske.[ch] and in
7490 lib/silcske/payload.[ch].
7492 * Added ^U functionality, clear input line. Patch from cras.
7494 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7496 * Mainly small bugfixes on core library. Fixed some debugging
7497 logging and buffer overflow in silclog.c.
7499 * Updated config.sub and config.guess on the distribution tree.
7501 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Added command lagging support in server. Client may execute
7504 commands now only once in two seconds.
7506 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Optimized packet reception. MAC computation and checking is now
7509 also more optimized. A lot previously duplicated code is now
7510 used as generic by both client and server.
7512 * Fixed key pair generation in clientutil.c
7514 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7516 * Added into lib/silccore/silcbufutil.[ch] new function;
7517 silc_buffer_realloc.
7519 * Moved generic packet sending/encryption functions to
7520 lib/silccore/silcpacket.[ch] from client and server. Some
7521 rewriting of the functions.
7523 * Moved all generic packet reception/decryption functions to
7524 lib/silccore/silcpacket.[ch] from client and server. The
7525 packet processing is now much cleaner in both client and server.
7526 These were major changes in both client and server.
7528 * Created many common functions in server to do packet sending.
7529 Previously code were duplicated a lot, this has been removed
7532 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Rewrote major parts of the ID cache system. Don't know
7535 whether it is better now or not but at least the API is more
7538 * Major rewrite on ID cache stuff on client because of the ID
7539 cache API changes. Added idlist.c to client.
7541 * Also major rewrite on ID cache stuff on server as well.
7542 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7543 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7544 in hand, instead they are all put into the ID cache system now.
7545 All server_idlist_* routines uses ID cache now instead of
7546 traversing its own lists (those lists does not exist anymore).
7547 SilcIDList though still exists. Also, SilcXXXEntry's are
7550 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7552 * Finally made the SKE implementation compliant to the protocol
7553 specification. All mp integers are now binary encoded as
7554 opposed being HEX encoded.
7556 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7559 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7560 functions: silc_[encode/decode]_pem. Also added function
7561 silc_encode_pem_file to PEM encode with newlines ('\n') for
7564 * SILC public keys are now encoded either PEM or binary. Same
7565 option is for private keys as well. By default private keys
7566 are binary encoded and public keys PEM encoded. Silly HEX
7567 encoding were removed.
7569 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7570 function to create fingerprints.
7572 * Fixed a bug in SHA1; does not change the original data anymore.
7574 * Partly implemented INFO command on client and server side.
7575 Fixed CLEAR command. Changes to SERVER command; show current
7576 server(s) when giving command without arguments. Added
7577 VERSION command to client.
7579 * Added check to server that unregistered connections cannot
7580 execute commands (unless it is specificly allowed).
7582 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * Fixed screen refresh.
7586 * Fixed channel joining bug from client. On some circumstances
7587 client tried to join to a channel it had already joined.
7589 * Added public key verification process into client's protocol.c.
7590 The client now verifies the public key from user and saves
7591 it into ~./silc/serverkeys/ directory.
7593 Added into: clientutil.[ch]: silc_client_verify_server_key.
7595 * Changed SKE protocol's silc_ske_initiator_finish function
7596 to accept callback function that verifies the received public
7597 key. Removed old silc_ske_verify_public_key function.
7599 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7602 silc_pkcs_private_key[_data]_set.
7604 * Made the password and public authentication more cleaner in
7605 server's protocol.c.
7607 * Removed historic and obsolete protocol `channel_auth' from
7608 both client and server.
7610 * Removed wrong way of sending command status messages from
7611 server to client in server's command.c. The old way violated
7612 protocol specification.
7614 Changes to silccore/silccommand.[ch]: removed
7615 silc_command_encode_status_payload -> not needed anymore,
7616 changed silc_command_encode_payload_va to accept extra
7617 argument on variable argument list. The argument type must
7618 now be provided to the function. Also, added new function:
7619 silc_command_encode_reply_payload_va which is same as
7620 normal command_encode_payload_va except command status type
7621 is provided as extra argument.
7623 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7625 * Added ~./silc directory handling. The directory includes the
7626 public and private keys for the client.
7628 Added silc_client_check_silc_dir, silc_client_create_identifier
7629 and silc_client_load_keys.
7631 * Implemented SILC protocol compliant public key. Added public
7632 and private key saving to and loading from files.
7634 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7635 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7636 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7637 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7638 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7640 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7641 silc_pkcs_load_[public/private]_key.
7643 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Added silc_server_get_route (route.[ch]) to get connection
7646 data for the fastest route for given ID.
7648 * Implemented INVITE command on client and server. The command
7649 were re-defined in the SILC Protocol Specification and the
7650 implementation now complies with the specification.
7652 * Implemented PING command on client and server.
7654 * Implemented NAMES command on client and server. The server side
7655 supports currently only normal server not router server yet.
7656 Some changes to NAMES definition in SILC protocol specification.
7658 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7660 * Implemented LEAVE command on client and server.
7662 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7663 again. This change was made to the protocol as well. Server
7664 should not violate the protocol specification anymore.
7666 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7668 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7669 was tested. SOCKS4 was not but should work anyway.
