1 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
4 ID length. It ignored that ID can be IPv6 based as well.
5 Affected file lib/silccore/silcpacket.h.
7 * Fixed the silc_id_id2str and silc_id_str2id to take the
8 IPv6 address offset's into consideration. Affecte file is
11 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
13 * Fixed the internal Unix scheduler functions to check for
14 NULL context they may receive. The affected file is
15 lib/silcutil/unix/silcunixschedule.c.
17 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
19 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
20 can specify different directory with --home command line
21 parameter. Affected files irssi/src/silc/core/client_ops.c,
24 * SILC-specific commands aren't now executed if the active server
25 isn't of SILC-type, so there won't be problems with having
26 IRC and SILC protocol support in same client. Affected files
27 irssi/src/silc/core/silc-channels.c, silc-servers.c,
30 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Improved the signal support in SILC Schedule. Added new
33 function silc_schedule_signal_call which is used by application
34 to mark a signal to be called. It is now safe to perform
35 any kind of tasks in signal callbacks since it is guaranteed
36 that the application specified signal callback is called
37 after the signal is over. Affected files are
38 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
40 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
42 * Added `name' field to SilcChannelPrivateKey to represent
43 application given name for the key. Moved also the context from
44 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
45 Added the `name' argument also to the function
46 silc_client_add_channel_private_key.
48 Added function silc_client_current_channel_private_key to set the
49 current channel private key in use.
51 Added "change" command to KEY command which can be used to change
52 the current channel private key. Bound the command also to
55 Also affected files lib/silcclient/client_channel.c,
56 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
58 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Added silc_rng_get_byte_fast function in to the
61 lib/silccrypt/silcrng.[ch].
63 * Changed the interface of silc_packet_assemble and the
64 silc_packet_send_prepare. If silc_packet_assmble is now
65 called the application does not call silc_packet_send_prepare
66 because the library will call it automatically. These
67 interfaces now also return a reference to the outgoing buffer
68 which includes the assembled packet, which the application can
69 use to encrypt the packet.
71 Affected files are lib/silccore/silcpacket.[ch],
72 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
73 silcd/packet_send.c, server_backup.c and packet_receive.c.
75 * Fixed a packet sending bug on very high load, where outgoing
76 packet queue wasn't handled correctly and packets got corrupted.
77 Affected files are lib/silcutil/*/silc*sockconn.c,
78 lib/silcclient/client.c and silcd/server.c.
80 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
82 * Added macro SILC_PACKET_DATALEN which can be used during
83 packet assembling to check whether the data to be added to
84 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
85 len is truncated until it fits it.
87 Added checks for maximum length of channel message payload and
88 private message payload also.
90 Added checks for maximum packet length in server and in
93 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
94 lib/silcclient/client.c, lib/silccore/silcchannel.c and
95 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
96 lib/silcclient/client_prvmsg.c.
98 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
100 * Added silc_server_packet_queue_purge call to the
101 silc_server_disconnect_remote to assure that all data in the
102 queue before disconnecting is sent to the network. Affected
105 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
107 * Added the deleting of server's own ID cache entry to the
108 silc_server_free function. Free also everything else that
109 has been allocated in silc_server_init. The affected file
112 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
114 * Added functions silc_parse_version_string, silc_version_to_num,
115 and silc_ske_parse_version to parse SILC protocol style version
116 strings. Affected files lib/silcutil/silcutil.[ch] and
117 lib/silcske/silcske.[ch].
119 * Added new configuration params: version_protocol, version_software
120 and version_software_vendor to specify what version the remote
121 host must at least be to be able to connect to server. The vendor
122 string can be regex matched too. Added new function
123 silc_server_connection_allowed to check maximum number of allowed
124 connections, and allowed versions for incoming connections.
125 Affected files are silcd/server.c, server_util.[ch] and
128 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Added preliminary support for signals in scheduler. The
131 signals we care about are now blocked always when the scheduler
132 is locked. This way we can synchronise the use of signal with
133 scheduler. It is guaranteed that when signal occurs the scheduler
134 is not locked, and thus new tasks can be safely added to the
137 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
138 to silc_schedule_internal_init and silc_schedule_internal_uninit.
139 Added new platform specific routines
140 silc_schedule_internal_signals_[un]block and
141 silc_schedule_internal_signal_[un]register.
143 Added new functions to SILC Schedule API:
144 silc_schedule_signal_[un]register. Each signal that application
145 is going to use should be registered to the scheduler.
147 Affected files are lib/silcutil/silcschedule.[ch],
148 lib/silcutil/*/silc*schedule.c.
150 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
152 * Check for unauthenticated client and server in the
153 silc_server_new_client and silc_server_new_server functions.
154 Affected file silcd/packet_receive.c.
156 * Added function silc_string_is_ascii to check whether given
157 string is 7-bit ASCII string. Affected files are
158 lib/silcutil/silcutil.[ch].
160 * Added function silc_id_is_valid_server_id into the
161 silcd/serverid.c and added checking for valid Server ID's in
162 silc_server_new_server. The Server ID must always be based
163 on the server's public IP address.
165 * Added logging of DISCONNECT packet message in the server.
166 Affected file silcd/server.c.
168 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
170 * Changed all library interfaces that use Global RNG to also
171 accept SilcRng as argument. Affected files are
172 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
173 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
174 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
175 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
178 * Added function silc_pkcs_generate_key to the
179 lib/silccrypt/silcpkcs.[ch] for applications so that they
180 don't need to do pkcs->pkcs->init calls anymore.
182 * Remove SilcSocketConnection from the SFTP API since it really
183 wasn't needed there. The application has the information
184 saved in its contexts anyway and the SFTP layer doesn't need
185 know about it. Affected files lib/silcsft/silcsftp.h and
186 lib/silcsftp/sftp_[server/client].c.
188 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
189 The SilcSimContext is not SilcSim.
191 * Fixed possible buffer overflows in silc_id_render in the
192 lib/silcutil/silcutil.c.
194 * On EPOC the global crypto module lists are not used at all
195 in the crypto library. Added support for using the constant
196 algorithm list on EPOC. Affected files are
197 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
200 * Fixed the handling of third parameter of KICKED notify, since
201 it was mistakenly updated to SILC Protocol 1.0 even though it
202 is to be included in 1.1. Since it is not in 1.0 it is not
203 mandatory, and this fix now handles it only if it is provided,
204 and it is not error if it is not provided. Affected file
205 lib/silcclient/client_notify.c.
207 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
209 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
210 client. Affected file irssi/src/silc/core/client_ops.c.
212 * Merged with Irssi 0.8.4 from irssi.org CVS.
214 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
216 * Check for valid socket connection in client entries before
217 sending any messages. Fixes a crash, but doesn't fix some
218 other underlaying bug that is lurking there. Affected
219 file silcd/packet_send.c.
221 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
223 * $usermode, $cumode and $cumode_space expandos shouldn't do
224 anything with non-SILC server records. Affected file
225 irssi/src/silc/core/silc-expandos.c
227 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
229 * Fixed the silc_net_check_[host/local]_by_sock to support
230 IPv6 bound sockets as well. Now they can return IPv6 addresses
231 as well. Affected file lib/silcutil/silcnet.c.
233 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
234 Affected lib/silcutil/unix/silcunixnet.c.
236 * Fixed ID rendering (at least on some platforms, not NetBSD)
237 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
239 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
241 * Added silc_hash_public_key and silc_hash_public_key_compare
242 functions to be used with SilcHashTable. They can be used to
243 hash public keys and compare public keys in hash table. Affected
244 file lib/silcutil/silcutil.[ch].
246 * Added support for specifying multiple public keys for Client
247 connection section in server configuration file. This makes it
248 possible to accept multiple public keys from same host, or to
249 make a section that accepts any incoming host, and have the
250 accepted public keys listed in the section.
252 Added functions silc_sever_[find/get]_public_key, added the
253 support for this actually to all connection sections but only
254 the Client section is currently allowed to specify multiple
257 Affected files are silcd/server.c, server_internal.h,
258 command.c, protocol.c, server_util.[ch], packet_receive.c.
260 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Merged Irssi 0.8.2 from irssi.org CVS.
264 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
266 * If silc_debug is TRUE, also output standard logging messages
267 to stderr with the debug output.
269 Made silc_log_reset_all() flushing all channels before returning.
270 Also fixed some documentation typos.
272 Affected files are lib/silcutil/silclog.[ch].
274 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Fixed the server to check correctly the amount of connections
277 from single host, by checking also the type of the connection.
278 Fixed also the comparison of number of connections and number
279 of allowed connections. Affected files are silcd/server.c,
282 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
284 * Fixed the USERS command reply to save the user's mode on the
285 channel as well. Fixed JOIN command reply to check whether a
286 client is on channel already and not join it twice. Affected
287 file lib/silcclient/command_reply.c.
289 * Added new file silc-expandos.c into irssi/silc/core/ to return
290 various stuff for various signal for the statusbar etc. updating.
291 Now Irssi SILC client prints channel user modes etc. on the
294 * The user mode (like server/router operator changes) is now shown
295 on the Irssi SILC client's statusbar. The affected files are
296 irssi/src/silc/core/client_ops.c, silc-expandos.c.
298 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
300 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
301 to SILC_SCHEDULE_[UN]LOCK macros.
303 * Added more error printing to logs in server code. Affected
304 files silcd/server.c and silcd/protocol.c.
306 * Fixed -S option parsing in Irssi SILC Client. Affected file
307 irssi/src/silc/core/silc-core.c.
309 * Added silc_buffer_alloc_size function. Affected file is
310 lib/silcutil/silcbuffer.h.
312 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
314 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
315 constants. Affected files in
316 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
319 * Changed the internal SFTP Memory FS table to const. Affected
320 file lib/silcsftp/sftp_fs_memory.c.
322 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Fixed the buffer formatting and unformatting routines to
325 check the size of 64 bits types with sizeof(). Affected
326 file is lib/silcutil/silcbuffmt.c.
328 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Removed 0.6.x backwards support.
332 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
334 * Changed all integer type names:
335 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
336 to avoid collisions with other libraries using same type names
339 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
341 * Added `prefer_ipv6' argument to the functions
342 silc_net_gethostbyname[_async]. If it is TRUE it will return
343 IPv6 address over IPv4. If FALSE IPv4 address is returned
344 even if IPv6 address was found. Affected files
345 lib/silcutil/silcnet.[ch].
347 * Added support silc_net_create_connection[_async] to fallback
348 to IPv4 address if IPv6 address could not be used (like if
349 it doesn't work on a specific system). Affected file in
350 lib/silcutil/unix/silcunixnet.c.
352 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Added silc_schedule_reinit function to do the enlarging
355 of the max tasks handling capabilities of the scheduler.
356 Affected files lib/silcutil/silcschedule.[ch].
358 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
360 * Added automatic extern "C" { ... } for C++ compilers so the
361 application does not need to define them. Affected file
362 includes/silcincludes.h.
364 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
365 old name went against naming convention. Applications now
366 include "silcclient.h" instead of "clientlibincludes.h".
367 Removed includes/clientlibincludes.h, it is redundant now.
369 * Renamed includes/version.h to silcversion.h.
371 * Added really preliminary support for OS/2 into the util
372 library. Only thread & mutex API is implemented, others
373 are still to be implemented. Created the lib/silcutil/os2/
374 directory. Created also file includes/silcos2.h.
376 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Added preliminary BeOS support into the util library.
379 Created lib/silcutil/beos/, and implemented all the needed
380 functions to support SILC on BeOS. Created also file
383 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
385 * Added proper initializations to silc's irssi code, so it's
386 now possible to load it as module. Affected files
387 irssi/src/silc/core/silc-core.c,
388 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
390 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
395 * Fixed the silcdoc document generator to correct generate
396 docs from all kinds of filenames. Affected files are
397 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
399 * ROBOdoc documented lib/silcutil/silcmemory.h.
400 Added also new function silc_memdup.
402 * Removed lib/silcutil/silcbufutil.h and moved those routines
403 to the lib/silcutil/silcbuffer.h.
405 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
407 * Added `user_count' to the SilcChannelEntry which now tells the
408 number of users on the channel. The user count is now saved
409 in normal server of global channels as well. Affected files
410 silcd/server.c, idlist.h, packet_receive.c and command.c.
412 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
413 include file utility functions.
415 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
416 instead of calling directly OS routines.
418 * Fixed NICK change printing in Irssi SILC Client. Fixed
419 KICKED notify printing in Irssi SILC Client. Affected file
420 irssi/src/silc/core/client_ops.c.
422 * Fixed a NICK change bug in client library, to not recreate the
423 client_entry->channels hash table everytime nick is changed.
424 Affected file lib/silcclient/client.c.
426 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
428 * ROBOdoc documented the lib/silcske/silcske.h, and improved
429 the SKE interface a bit.
431 * Fixed padding problem in PKCS#1. The padding was not actually
432 random since the random number generator was used incorrectly.
433 This security bug affects only when encrypting with PKCS#1, and
434 it is not currently used at all in SILC. SILC only use signing
435 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
437 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Rewrote the notify handling in Irssi SILC client to not call
440 the events as signals. Fixes problems with Perl support.
441 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
443 * Send the auto-nicking NICK command in client library with
444 little timeout after connecting. The affected file is
445 lib/silcclient/client.c.
447 * Added following new config file settings:
448 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
449 key_exchange_timeout, conn_auth_timeout, connections_max,
452 Implemented all the new config settings handling in the server.
454 Optimized the use of SKE Mutual flag usage. Use it only
455 if connection authentication protocol is not based in public
458 Renamed all SilcServerConfigSection* to SilcServerConfig*
459 to have a bit shorter names.
461 Affected files silcd/serverconfig.[ch], server.[ch], and
464 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
466 * Cleaned up the listening sockets code, preparing for the rehash
467 support. Affected file is silcd/server.c.
469 * Fixed some output messages. Affected files are silcd/silcd.c,
472 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Create lib/doc/silcrng_intro.html document as introduction
475 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
477 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
479 * Fixes to the silcd config template. Affected file is
480 doc/example_silcd.conf.in.
482 * Removed type casts from silc_calloc(), conforming to the
483 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
485 * Removed param_name member from client, server, and router
486 section structs, now identifying the param directly.
488 Added CONFIG_FREE_AUTH macro in config file parsing.
490 Affected files are silcd/serverconfig.[ch].
492 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
494 * Fixed command line parameter handling. All SILC initialization
495 is now done in silc_core_init() which also fixes autoconnecting
498 Affected files irssi/src/silc/core/silc-core.c,
499 irssi/src/fe-text/silc.c.
501 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Added new configuration options and blocks:
504 keepalive_secs, reconnect_count, reconnect_interval,
505 reconnect_interval_max, reconnect_keep_trying and
506 require_reverser_lookup. Added ConnectionParam block, and
507 implemented the connection parameters when connecting as
508 initiator and when accepting connections as responder.
510 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
511 whether given configuration value has been given already.
513 Affected files silcd/serverconfig.[c], server.[c].
515 * Splitted the doc/example_silcd.conf.in. Separated the crypto
516 algorithm parts and created new file silcalgs.conf, that
517 is now included from the example_silcd.conf.in.
519 * Optimized the silc_server_connect_to_router_second to take
520 the connection configuration object from the SilcServerConnection
521 object instead of finding it during the connecting phase.
522 Added the configuration object to SilcServerConnection struct.
523 Affected files silcd/server_internal.h, server.c.
525 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
527 * Add the client on channel after it was resolved at the
528 channel message receiving, and it was not already on the
529 channel. Affected file lib/silcclient/client_channel.c.
531 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Fixed the public key authentication to allocate always the
534 destination signature buffer instead of using static buffer.
535 Affected file silcd/protocol.c.
537 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
539 * Unified the serverconfig.[ch]'s helper function interface.
540 Affected file silcd/serverconfig.[ch].
542 * Removed doc/example_silc.conf.in since it is redundant.
543 The make install will now install irssi/silc.conf file.
545 * Added new Passphrase and Publickey authentication methods to
546 config file, allowing both public key and passphrase based
547 authentication to be set at the same time.
549 Added `prefer_passphrase_auth' setting in config file which
550 can be used to set to prefer passwd auth if both passwd and
551 public key is set. If not set, public key is preferred.
552 This has effect only when being initiator (responder will try
555 Added support for authentication with passphrase and public key
556 at the same time. The passphrase is tried first always since
557 it is faster to check.
559 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
561 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
563 * Merged the new SILC Config library, with the server parsing
564 support. Read the header file silcconfig.h or the toolkit
565 documentation for the news. Affected files are
566 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
567 silcd/command.c silcd/packet_receive.c silcd/packet_send.c

585 Sat Feb 9 14:54:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Allow zero length channel messages inside the Channel Message
588 Payload. Affected file lib/silccore/silcchannel.c.
590 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
593 * Removed lib/silcclient/README and created HTML file
594 lib/silcclient/silcclient_using.html, which is now included
595 as part of Toolkit documentation.
597 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
599 * Fixed CUMODE_CHANGE notify handling to change the mode of
600 correct client. Affected file lib/silcclient/client_notify.c.
602 * Make silc_rng_alloc fail if it cannot allocate the sha1
603 hash algorithm. Affected file lib/silccrypt/silcrng.c.
605 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
607 * Fixed the file transfer's key agreement payload to include
608 zero port also if the hostname is NULL because it could not
611 Call file transfer monitor callback now also if error occurs
612 during key agreement protocol.
614 Changed the silc_client_file_send interface to return the
615 SilcClientFileError instead of session id. The session ID
616 is returned into pointer provided as argument.
618 Check that the file exists locally before sending the
619 file transfer request at all.
621 Affected file lib/silcclient/client_ftp.c, silcapi.h.
623 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
624 error than can occur while key agreement protocol. Affected
625 file lib/silcclient/silcapi.h.

628 is changed and +k mode is set in the channel. Affected file
629 irssi/src/silc/core/silc-channels.c.
631 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
632 SILC_LOG_WARNING to give out Warning and not Error. Affected
633 file lib/silcutil/silclog.c.
635 * Fixed the channel message payload decryption in the function
636 silc_channel_message_payload_decrypt to not modify the original
637 buffer before it is verified that the message decrypted
638 correctly. Otherwise, next time it is called with correct
639 channel key it won't encrypt since the payload is corrupted.
640 Affected file lib/silccore/silcchannel.c.
642 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
644 * Do not constantly resize the window. A fix patch by cras.
645 Affected file irssi/src/fe-text/screen.c.
647 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
650 Affected file lib/silcutil/silcnet.c.
652 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Fixed a bug in hash table internal routine for traversing
655 the table with foreach callback. The current entry may
656 become invalid in the callback but it was referenced after
657 the callback returned.
659 Do not allow auto rehashing of hash table during the
660 silc_hash_table_foreach operation, for same reasons as it is
661 not allowed for SilcHashTableList. Affected files are
662 lib/silcutil/silchashtable.[ch].
664 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
666 * Defined DLLAPI into silcincludes.h and silcwin32.h for
667 Win32 DLL. extern's in header files are now declared with
670 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
672 * Fixed private message handling. It used some old code that
673 caused the client to crash. Affecte file is
674 lib/silcclient/client_prvmsg.c.
676 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Added function silc_client_add_channel,
679 silc_client_replace_channel_id, and removed functions
680 silc_client_new_channel_id and silc_idlist_get_channel_by_id
683 * Added cross reference of the joined channels to the
684 SilcClientEntry, and changed the SilcChannelEntry's
685 users list to SilcHashTable. The affected files are
686 lib/silcclient/idlist.[ch].
688 * Fixed a bug in hash table tarversing. While the hash table
689 is traversed with SilcHashTableList the table must not be
690 rehashed. It is now guaranteed that auto rehashable tables
691 are not rehashed while tarversing the list. Also defined that
692 silc_hash_table_rehash must not be called while tarversing
693 the table. Added function silc_hash_table_list_reset that must
694 be called after the tarversing is over. The affected files are
695 lib/silcutil/silchashtable.[ch].
697 * Changed all hash table traversing to call the new
698 silc_hash_table_list_reset in server and in client library.
700 * Added function silc_client_on_channel to return the
701 SilcChannelUser entry if the specified client entry is joined
702 on the specified channel. This is exported to application as
703 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
705 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
707 * Fixed founder regaining problem with JOIN command on normal
708 server. The notify for mode change must be sent always and
709 not only if !cmd->pending. Affected file silcd/command.c.
711 * Fixed the WHOWAS command's reply sending to support the
712 lists correctly. Affected file silcd/command.c.
714 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
716 * When sending JOIN command to router for processing the
717 sender's old command identifier was not saved back to the
718 sender's command context, fixed now. The affected file is
721 * Create the key in JOIN command of the router did not return
722 the channel key, added check for this. Affected file is
725 * Fixed a channel ID update bug in JOIN command reply. Do
726 not directly upgrade the ID but call the function
727 silc_idlist_replace_channel_id if the ID was changed.
728 Affected file silcd/command_reply.c.
730 * Fixed memory leaks from command calling if it would fail.
731 Affected file silcd/command.c.
733 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
735 * Applied patches from cras:
737 Memory leak fixes around libaries, irssi window resize fix,
738 new silclist.h and silcdlist.h, all extern inline changed to
741 * Removed dotconf from lib/dotconf, not needed anymore.
743 * Removed TRQ from lib/trq, not needed anymore.
745 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
746 with server connections. Later this will be configurable
747 in config file after new config file is done. Affected file
750 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
752 * Fixed a crash in server related to channel announcements.
753 Affected file silcd/server.c.
755 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Fixed memory leaks in silc_server_create_new_channel*
758 functions. Affected file silcd/server.c.
760 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
761 which ID was changed. This way the router will send the
762 user list for the channel again, and server won't be in
763 desync in some rare circumstances. Affected file is
764 silcd/packet_receive.c.
766 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
768 * Check for NULL socket pointer in the function
769 silc_server_packet_send_to_channel_real. Affected file
772 * Fixed the BAN notify handling to correctly remove ban
773 list. Affected file silcd/packet_receive.c.
775 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
777 * Fixed some header addition to Toolkit distribution in
778 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
780 * Added lib/silcclient/client_ops_example.h as an template
781 file for application programmers to quickly start using
782 the SilcClientOperation functions in their application.
783 Updated the lib/silcclient/README as well to tell about this
784 nice file made available.
786 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
788 * Call silc_server_remove_from_channels when removing client
789 entry when NO_SUCH_CLIENT_ID was received. Affected file
790 is silcd/command_reply.c.
792 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
794 * Added server & router operator statistics updating. Affected
795 file silcd/packet_receive.c and silcd/command.c.
797 * Fixed the SERVER_SIGNOFF notify handling on normal server
798 not to save the history information for clients. Same was
799 fixed earlier in remove_clients_by_server function, but not
800 here. Affected file silcd/packet_receive.c.
802 * Raised the default connection-retry count from 4 to 7 in
803 server. Affected file silcd/server.h.
805 * Cancel any possible reconnect timeouts when we start the
806 key exchange. Affected file silcd/server.c.
808 * Do not reconnect on connection failure when SCONNECT was
809 given. Affected files silcd/server.[ch].
811 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
813 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
815 * Fixed the NICK command to always give the unformatted
816 nickname to the one giving the NICK command. If unformatted
817 nickname is cached already it will be formatted and the
818 local entry will always get the unformatted nickname.
819 Affected file lib/silcclient/idlist.c.
821 * Fixed some double frees from client library commands.
822 Affected file is lib/silcclient/command.c.
824 * Fixed CUMODE command in server to assure that no one can
825 change founder's mode than the founder itself, there was a
826 little bug. Affected file silcd/command.c.
828 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
830 * Removed the SilcClientCommandDestructor from the client
831 libary, it is not needed anymore. Affected files are
832 lib/silcclient/silcapi.h, command[_reply].[ch],
833 client_notify, idlist.c.
835 * Fixed GETKEY command to first resolve client, and then
836 resolve the server only if the client was not found, instead
837 of resolving both at the same time. Affected file is
838 lib/silcclient/command.c.
840 * Added silc_client_start_key_exchange_cb and lookup the
841 remote hostname and IP address before starting the key
842 exchange with server. The affected file is
843 lib/silcclient/client.c.
845 * The server's public key is now saved using the IP address
846 of the server and not the servername for the filename.
847 The hostname public key filename is checked as an fall back
848 method if the IP address based filename is not found.
850 Fixed the GETKEY command to save the fetched server key
853 Print the remote server's hostname now when new key is
854 received during connection process. Affected file is
855 irssi/src/silc/core/client_ops.c.
857 * Return always our own public key to the client if it asks
858 for it with GETKEY command. Affected file silcd/command.c.
860 * Removed the use_auto_addr variable from default config
861 file since it was in wrong section. Affected file is
864 * Fixed TOPIC_CHANGE notification to not route it when it
865 was sent using silc_server_send_notify_to_channel function.
866 Affected file silcd/command.c.
868 * Fixed silc_server_send_notify_kicked to send the kicker's
869 Client ID also, it was missing. Affected files are
870 silcd/command.c, silcd/packet_send.[ch].
872 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
874 * Do not save client history information in SERVER_SIGNOFF.
875 Fixes the bug in normal server that it does not detect
876 the client becoming valid after the server becomes back
877 online. Affected file silcd/server_util.c.
879 * Added `sock_error' field into the SilcSocketConnection
880 context. When error occurs during socket operation (read
881 or write) the error is saved. Added also new function
882 silc_socket_get_error to return human readable socket error
883 message. Affected files are lib/silcutil/silcsockconn.[ch],
884 lib/silcutil/unix/silcunixsockconn.c, and
885 lib/silcutil/win32/silcwin32sockconn.c.
887 * The server now prints the socket error message in the
888 signoff for client. Affected file silcd/server.c.
890 * Fixed the `created' channel information sending from router
891 to server in JOIN command. Checks now whether the channel
892 really was created or not and set it according that.
894 Fixed the JOIN command to use the client entry's current
895 ID during the joining procedure instead of the one it sent
896 in the command (it is checked though), since it can change
897 between the packet processing and command processing, and
898 would just case unnecessary pain in the client end. Affected
899 file silcd/command.c.
901 * Fixed a channel key payload sending to use correct channel
902 ID when the server was forced to change the channel's ID by
903 router. Router sent the key payload with the old Channel ID.
904 Affected file silcd/packet_receive.c.
906 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Call silc_server_save_channel_key only if the key payload
909 was provided in the JOIN command's command reply. Affected
910 file silcd/command_reply.c.
912 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Fixed silc_mp_sizeinbase to return the value correctly with
915 MPI. Affected file lib/silcmath/mp_mpi.c.
917 * Fixed the stop_server signal to correctly stop the scheduler
918 and gracefully stop the server when SIGTERM or SIGINT signals
919 are received. Affected file silcd/silcd.c.
921 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
923 * Simple handling of TERM and HUP signals. Also added some log
924 flushing call around. Affected file is
927 * Fixed small bugs in silclog.c. Now buffering output will take
928 effect after 10 seconds since startup: This will ensure that
929 no important startup messages are lost. Also output redirection
930 will preserve original format ([Date] [Type] message).
931 Affected file is lib/silcutil/silclog.c.
933 * Added two options to the config file, in the logging section:
934 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
935 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
937 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
939 * Do not print the warning about log files not being initialized
940 more than once to avoid excess logging. Affected file is
941 lib/silcutil/silclog.c.
943 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
944 the SIM copying in make install in Makefile.am.pre.
946 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
948 * Rewritten silclog APIs. Globally interesting changes follows:
949 silc_log_set_files() changed to silc_log_set_file().
950 silc_log_set_callbacks() changed to silc_log_set_callback().
951 ROBOdoc documented silclog header file.
952 SilcLogCb now returns bool to wether inihibit the default
953 handler or not (to keep the old behaviour return always TRUE).
954 The new APIs should also fix the problem of the
955 silcd_error.log file that was written in the current directory.
958 Log files streams will remain opened after silc_log_set_file()
959 call, means less CPU usage notably on high traffic servers.
960 File streams are now full buffered, and flushed to the disk
961 every 5 minutes, lesses HD activity and CPU usage.
962 Messages can be redirected, allowing admins to configure
963 one single logfile for all server messages.
964 the silc_log_quick global variable to activate fast-logging.
965 Affected files lib/silcutil/silclog.[ch]
967 * Changed some code to conform new silclog APIs. Affected
968 files are doc/example_silcd.conf.in, silcd/server.c
969 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
972 * Fixed a memory leak that could occur in some situations.
973 Affected file silcd/serverconfig.c.
975 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
977 * Added the silc_client_del_client to remove the client from
978 all channels as well. Affected file lib/silcclient/idlist.c.
980 * Fixed the client library to correctly remove the client
981 from all channels when the client entry is being destroyed.
982 Affected file lib/silcclient/client_notify.c, command.c.
984 * Added auto-nicking support to the client library. If the
985 applicatio now sets client->nickname it will be sent to the
986 server after connecting by the library. This way for example
987 SILCNICK (or IRCNICK) environment variables will have effect
988 and always change the nickname automatically to whatever
989 it is wanted. Affected file lib/silcclient/client.[ch].
991 * Renamed silc_server_command_bad_chars to the
992 silc_server_name_bad_chars and moved it to the
993 silcd/server_util.[ch]. Added also new function
994 silc_server_name_modify_bad to return nickname that
995 includes bad characters as new nickname without those
996 bad characters. This check and modify is now used in
997 silc_server_new_client when the username is initially set
998 as nickname, so it must be checked to be valid nickname.
999 Affected file silcd/packet_receive.c.
1001 * The nickname length is now taken from the packet for real
1002 and not trusted to strlen() since it clearly can return
1003 wrong length for nickname including bad characters. This
1004 also applies to channel names. Affected file silcd/command.c.
1006 * Removed the lib/silcsilm/modules directory. Modules are now
1007 compiled into the lib/silcsim. Fixed the copying of the
1008 modules to follow symbolic links in Makefile.am.pre.
1010 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1012 * Fixed silc_string_regexify list creation. Fixes bugs with
1013 BAN and INVITE commands in server. The affected file is
1014 lib/silcutil/unix/silcunixutil.c.
1016 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Removed the command destructor entirely from the server's
1019 command and command reply routines. It is not needed, and
1020 its usage was buggy and caused crashes. Affected files are
1021 silcd/command[_reply].[ch].
1023 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * Cancel protocol and NULL sock->protocol if timeout
1026 occurred during protocol. Affected file silcd/server.c.
1028 * Cancel protocol timeouts always before calling the final
1029 callback, to assure that after final callback is called
1030 no other state will be called for the protocol anymore.
1031 Affected file silcd/protocol.c.
1033 * Print error log if incoming connection configuration could
1034 not be found. Affected file silcd/server.c.
1036 * Fixed JOIN command to correctly save the founder mode
1037 to the client on normal SILC server, when the channel
1038 was created by the router. Affected file silcd/command.c.
1040 * Fixed LIST command (hopefully) to send correct reply
1041 packets. Affected file silcd/command.c.
1043 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1045 * The silc_packet_receive_process now returns FALSE if the
1046 read data was invalid packet, and TRUE if it was ok.
1048 The server now checks that if unauthenticated connection
1049 sends data and its processing fails the server will close
1050 the connection since it could be a malicious flooder.
1052 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1054 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Make sure the warning about error opening a log file is
1057 printed only once and not everytime it fails (produces
1058 too much useless log). Affected file lib/silcutil/silclog.c.
1060 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1062 * Made the silc_server_daemonise() function more readable.
1063 Affected file silcd/server.c.
1065 * Pid file is now optional, the user may comment it out from
1066 the config file. Removed define SILC_SERVER_PID_FILE, we
1067 don't need a default any longer. Affected file
1068 configure.in.pre, lib/Makefile.am.pre.
1070 * Make some use of the pid file. The server now dies at startup
1071 if it detects a valid pid file on his path. The server would
1072 die anyway in this circumstance, because of the bind() failure.
1073 Affected file silcd/silcd.c.
1075 * No longer compiling lib/dotconf.
1077 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Fixed JOIN command parsing not to crash. Affected file
1080 lib/silcclient/command.c.
1082 * Fied the NICK_CHANGE notify to add the new client entry
1083 even it is resolved. This removes an <[unknown]> nick
1084 thingy bug in the client. Affected file is
1085 lib/silcclient/client_notify.c.
1087 * Do not try to allocate 0 bytes (efence does not like it)
1088 in lib/silccore/silccomand.c when encoding payload.
1090 * Do not take IRCNICK as nickname in Irssi SILC client since
1091 it is not possible to set nickname before hand connecting
1092 the server (TODO has an entry about adding auto-nicking
1095 * Changed the silc_server_command_pending to check whether
1096 there already exists an pending entry with the specified
1097 command, command identifier and pending callback. This is
1098 to fix IDENTIFY and WHOIS related crashes that may register
1099 multiple pending commands with same identifier. Affected
1100 file silcd/command.c.
1102 * Fixed the server to reconnect to the router even if it
1103 was already reconnecting and EOF was received. This to
1104 fix a possibility that the server wouldn't ever try to
1105 auto-reconnect to the router. Affected file silcd/server.c.
1107 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1109 * Fixed the server's password authentication to use the
1110 length of the locally saved password, and not the one
1111 sent in the packet. Affected file silcd/protocol.c.
1113 * Fixed same password authentication problem in the
1114 Authentication Payload handling routines in
1115 lib/silccore/silcauth.c.
1117 * Yet another password authentication problem fixed with
1118 channel password handling in silcd/command.c.
1120 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * If first character of string in silc_parse_userfqdn is '@'
1123 then do not parse it. Affected file is
1124 lib/silcutil/silcutil.c.
1126 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Fixed minor bug in IDENTIFY command reply sending, which
1129 caused various weird problems during JOIN when it was
1130 resolving names for users. Affected file silcd/command.c.
1132 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Fixed the IDENTIFY command reply sending to chech better valid
1135 clients. It was possible to send incomplete list of replies.
1136 Affected file silcd/command.c.
1138 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Added silc_client_command[s]_[un]register functions now to
1141 dynamically register the commands in client library. Removed
1142 the static table of commands. This allows the client library
1143 to call commands without causing the application to know about
1144 what commands library has called.
1146 Removed the INFO command reply kludge to detect when the command
1147 was called by library. Now library use its own command reply
1148 function for INFO command.
1150 Added function silc_client_command_call to call a command.
1151 Application can use it to call command, not access the structure
1154 Now all commands that are sent by the client library (not
1155 explicitly sent by application) use own command reply functions.
1157 Affected files around lib/silcclient/ and in
1158 irssi/src/silc/core/.
1160 * Fixed the WHOIS command reply sending to chech better valid
1161 clients. It was possible to send incomplete list of replies.
1163 Fixed the WHOIS and IDENTIFY to send the request to router
1164 if normal server did not do it and did not find any results.
1166 Affected file silcd/command.c.
1168 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1170 * Moved the internal data from SilcClient context into its
1171 own file, not accesible to application. Affected files
1172 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1173 and other files in client library.
1175 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1177 * Added doc/examples installation target in Makefile.am.pre.
1180 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1182 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1183 commands the found client entry will be removed from the
1184 cache, after notifying application about the error. Affected
1185 file lib/silcclient/command_reply.c.
1187 * Changed the /MSG to check for exact nickname user gave, and
1188 not let `nick' match `nick@host' if it is only one found. Now,
1189 user must type the exact nickname (like nick@host2) even if
1190 there are no more than one same nicks found. This is to avoid
1191 a possibility of sending nickname to wrong nickname since
1192 `nick' could match `nick@host'. Affected file is
1193 irssi/src/core/silc-servers.c.
1195 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Do not print "you are now server operator" or similar when
1198 giving /away command. Affected files are
1199 irssi/src/silc/core/client_ops.c, silc-servers.h.
1201 * Made the silc_server_command_pending_error_check to send
1202 the same command reply payload it received back to the
1203 original sender of the command. This way all arguments
1204 that was received by the server will be received by the
1205 client too. Affected file silcd/command.c.
1207 * Added the silc_idcache_add to return the created cache entry
1208 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1210 * Add global clients to expire if they are not on any channel.
1211 This is because normal server will never know if they signoff
1212 if they are not on any channel. The cache expiry will take
1213 case of these entries. This is done by normal servers only.
1214 The affected files are silcd/command_reply.c,
1215 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1217 * If server receives invalid ID notification for WHOIS or
1218 IDENTIFY and the ID exists in the lists, it is removed.
1219 Affected file silcd/command_reply.c.
1221 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1222 in client then client entry that it matches is searched and
1223 the nickname is printed on the screen for user. Affected
1224 file irssi/src/silc/core/client_ops.c.
1226 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Use cache entry expire time in the LIST command reply to
1229 purge old entries from the cache after the LIST command
1230 reply has been received. This way we don't have non-existent
1231 entries in the cache for too long. Affected file is
1232 silcd/command_reply.c.
1234 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1236 * If we are normal server, and we've not resolved client info
1237 in WHOIS or IDENTIFY from router, and it is global client,
1238 we'll check whether it is on some channel. If it is not
1239 then we cannot be sure about its validity and will resolve it
1240 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1241 file silcd/command.c.
1243 * Search channel by name (if possible) rather than by ID
1244 in IDENTIFY command's command reply. Affected file is
1245 silcd/command_reply.c.
1247 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1250 Updated specs and implemented it. Affected file silcd/command.c,
1251 silcd/packet_send.c and silcd/packet_receive.c.
1253 * Implemented the <founder auth> payload handling in the JOIN
1254 command. If provided all conditions for channel joining
1255 except requirement to provide correct passphrase can be
1256 overrided by the channel founder. Updated the protocol specs.
1257 Affected file silcd/command.c.
1259 Added support for founder auth in JOIN command in client
1260 library. Fixed the parsing of the JOIN command now to support
1261 all options as they should be. The affected file is
1262 lib/silcclient/command.c.
1264 * Optimized the WHOIS and IDENTIFY commands to send the request
1265 to router only if it includes nicknames or other names. If
1266 they include only IDs then check the local cache first before
1267 routing. Affected file is silcd/command.c.
1269 * Added channels topic announcements. Affected file is
1270 silcd/packet_receive.c and silcd/server.c.
1272 * Fixed the silc_server_send_notify_topic_set to really destine
1273 the packet to channel. Affected file silcd/packet_send.c.
1275 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1276 library. Affected file lib/silcclient/client_notify.c.
1278 * Added UMODE announcements. Affected file silcd/server.c.
1280 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Memory leak fixes in:
1284 lib/silcutil/silcsockconn.c
1285 lib/silcske/silcske.c
1286 lib/silcske/groups.c
1288 lib/silccrypt/silcpkcs.c
1289 lib/silccore/silccommand.c
1290 lib/silccore/silcidcache.c
1295 * ROBOdoc documented the lib/silcske/groups.h file and a
1296 bit changed the interface for better.
1298 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1300 * Update the client entry context in the ID cache after
1301 nick change. Affected file lib/silcclient/command.c.
1302 Fixes the CUMODE command when regaining founder privileges,
1303 and a little WHOIS problem.
1305 * Fixed silc_net_gethostbyname to correctly call the
1306 inet_ntop. Affected file lib/silcutil/silcnet.c.
1308 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1310 * Added IPv6 support checking to the configure.in.pre, added
1311 also --enable-ipv6 option to override the check. Affected
1312 file configure.in.pre.
1314 * The silc_thread_create now calls the start function
1315 directly if threads support is not compiled in. Removes
1316 ugly #ifdef's from generic code. Affected files are
1317 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1319 * Added silc_net_gethostby[name/addr]_async to asynchronously
1320 resolve. Affected files are lib/silcutil/silcnet.[ch].
1322 * Added support for rendering IPv6 based server, client and
1323 channel IDs. Affected file lib/silcutil/silcutil.c.
1325 * Added support for creating IPv6 based server IDs. Affected
1326 file is silcd/serverid.c.
1328 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1330 * Added silc_net_gethostby[addr/name] into the
1331 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1332 routines. Added silc_net_is_ip[4/6]. Affected file is
1333 lib/silcutil/unix/silcunixnet.c. All routines that take
1334 address as argument now supports both IPv4 and IPv6 addresses.
1336 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1338 * Fixed LIST command reply sending in server. Affected file
1341 * Server now sends the kicker's client ID in the KICK notify
1342 to the kicked client. Affected file silcd/command.c.
1344 * The client library now parses the kickers client ID and
1345 UI displays it. Affected files lib/silcclient/client_notify.c
1346 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1348 * Made all payload parsing function prototypes consistent.
1349 They all take now const unsigned char * and uint32 pair as
1350 the payload data instead of SilcBuffer. Changes all around
1351 the source tree. Other unsigned char* -> const unsigned char*
1352 changes around the tree as well.
1354 * Optimized SFTP client and server packet sending not to
1355 allocate new buffer for each packet but to recycle the
1356 first allocated buffer. Affected files are
1357 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1359 * Optimized the SFTP client to use SilcList instead of
1360 SilcDList for requests, because it is faster. Affected file
1361 is lib/silcsftp/sftp_client.c.
1363 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1364 into lib/silccore/silcid.[ch].
1366 Renamed silcpayload.[ch] into silcargument.[ch].
1368 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * If client entry is deleted with active key agreement
1371 session, abort the session.
1373 The silc_client_abort_key_agreement now calls the completion
1374 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1376 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1379 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Don't use __restrict in older GCC's. Affected file is
1382 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1384 * silc_net_localhost now attempts to reverse lookup the
1385 IP/hostname. Affected file lib/silcutil/silcnet.c.
1387 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1388 command. It can be used to gain founder privileges at
1389 the same time when joining the channel.
1391 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1392 kicker's client ID as well. Updated protocol specs.
1394 Defined that the server must send SILC_COMMAND_IDENTIFY
1395 command reply with error status to client who sent
1396 private message with invalid client ID.
1398 Updated the protocol specification.
1400 * Added silc_server_send_command_reply to send any
1401 command reply. Affected file silcd/packet_send.[ch].
1403 * Added silc_id_payload_encode_data to encode ID payload
1404 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1406 * The server now send IDENTIFY command reply with error
1407 status if client ID in private message is invalid. Affected
1408 file silcd/packet_receive.c.
1410 * Save the server key file with server's IP address in
1411 the filename instead of hostname. The affected file is
1412 irssi/src/silc/core/client_ops.c.
1414 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1419 * Added libtool support for compiling shared objects in
1420 lib/silcsim. Affected file configure.in.pre and
1421 lib/silcsim/Makefile.am. Original patch by cras.
1423 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Pid file configuration, and server's config file fixes
1426 patch by toma. Updated CREDITS file.
1428 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Fixed silc_client_channel_message to not try to decrypt
1431 the message twice if it resolved the destination client
1432 information. This could cause of dropping one channel
1433 message. Affected file lib/silcclient/client_channel.c.
1435 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1438 lib/silcclient/client.c. This function is used when the SILC
1439 Client is run under some other scheduler, or event loop or
1440 main loop. On GUI applications, for example this may be
1441 desired to used to run the client under the GUI application's
1442 main loop. Typically the GUI application would register an
1443 idle task that calls this function multiple times in a second
1444 to quickly process the SILC specific data.
1446 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1448 * Fixed silc_server_drop() for dropping the supplementary
1449 groups as well, this could cause a security hole on some
1452 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1454 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1457 * Write PID file after dropping privileges. Added -F option
1458 to run server on foreground. A patch by debolaz.
1459 Affected files silcd/server.c, silcd/silcd.c.
1461 * Fixed MOTD to return the MOTD file server name. Affected
1462 file silcd/command.c.
1464 * Added INFO command reply handling to the Irssi SILC Client.
1465 Affected file irssi/src/silc/core/client_ops.c.
1467 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Fixed the silc_idcache_list_* routines to really support
1470 the dynamic list. Fixes a crash. Affected file is
1471 lib/silccore/silcidcache.c.
1473 * Fixed the LIST command reply to really call LIST command's
1474 pending callbacks. Affected file silcd/command_reply.c.
1476 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Update conn->local_entry->nickname after giving NICK
1479 command. Affected file lib/silcclient/command.c.
1481 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1483 * Added the [pid] option to the silcd configuration file
1485 Affected files: serverconfig.[ch] and silcd.c
1487 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Save fingerprint in WHOIS command reply in server.
1490 Affected file silcd/command_reply.c.
1492 * Fixed NICK commands pending callback registration.
1493 Affected file lib/silcclient/command.c.
1495 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Use ++server->cmd_ident when sending commands in server,
1498 instead of random number. Affected file silcd/command.c.
1500 * Fixed GETKEY command reply to call actually GETKEY pending
1501 command callbacks. Affected file silcd/command_reply.c.
1503 * A bit stricter check for nicknames. Check for same nickname
1504 in NICK command also. Affected file silcd/command.c.
1506 * Do not call INFO command everytime client ID changes, only
1507 during first connecting. Affected file lib/silcclient/client.c.
1509 * Set the new nickname only after successful command reply for
1510 NICK command is returned by server. Affected file
1511 lib/silcclient/command.c.
1513 * Remove nicknames from nicklist during server_signoff notify.
1514 Should fix /NAMES bit more. The affected file is
1515 irssi/src/silc/core/silc-channels.c.
1517 * Added `fingerprint' field to the SilcIDListData in the
1518 silcd/idlist.h to hold the fingerprint of the client's
1521 Send the fingerprint of the client's public key in WHOIS
1524 Affected files silcd/command.c, and silcd/idlist.[ch].
1526 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1527 create fingerprint from given data.
1529 * Show the fingerprint of the client's public key in WHOIS.
1530 Affected files irssi/src/module-formats.[ch] and
1531 irssi/src/silc/core/client_ops.c.
1533 * Format the multiple same nicknames also during JOIN and
1534 NICK_CHANGE notifys. Affected file is
1535 lib/silcclient/client_notify.c.
1537 * Do not print error on screen for invalid private message
1538 payload since it can come if someone is sending private
1539 messages with wrong key. Affected file
1540 lib/silccore/silcprivate.c.
1542 * Fixed multiple concurrent /PING crash. Affected file
1543 lib/silcclient/command.c.
1545 * Changed the wrong ID encoding. All IP addresses must be
1546 in MSB first order in encoded format. They were encoded
1547 wrong and was in LSB format. Affected files are
1548 silcd/serverid.c, lib/silcutil/silcutil.c.
1550 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1552 * Call the `connect' client operation through the scheduler
1553 in case of error. Affected file lib/silcclient/client.c.
1555 * Call the `failure' client operation even if the error
1556 occurred locally during a protocol. Affected file is
1557 lib/silcclient/protocol.c.
1559 * Added support of sending LIST command to router from normal
1560 server. This way normal server can get list of all channels
1561 in the network too. Fixed the channel list sending in the
1562 server too. Affected files are silcd/command.c, and
1563 silcd/command_reply.[ch].
1565 * Added silc_server_update_channels_by_server and
1566 silc_server_remove_channels_by_server. They are used during
1567 disconnection of primary router and in backup router protocol.
1568 Affected file silcd/server_util.[ch], silcd/server.c and
1569 silcd/server_backup.c.
1571 * Fixed channel adding to global list in IDENTIFY command
1572 reply in server. Affected file silcd/command_reply.c.
1574 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * If the incoming packet type is REKEY or REKEY_DONE process
1577 that packet always synchronously. Fixes yet another MAC
1578 failed error on slow (dialup) connections. Affected file
1579 lib/silcclient/client.c and silcd/server.c.
1581 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Call check_version SKE callback for initiator too. Affected
1584 file lib/silcske/silcske.c.
1586 * Implemented fix for security hole found in the SKE that was
1587 fixed in the specification few days back; the initiator's
1588 public key is now added to the HASH value computation.
1589 Added backwards support for the old way of doing it too, for
1590 old clients and old servers. Affected file is
1591 lib/silcske/silcske.c.
1593 * Enabled mutual authentication by default in SKE. If initiator
1594 is not providing mutual authentication the responder will
1595 force it. This will provide the proof of posession of the
1596 private key for responder. The affected files are
1597 lib/silcclient/protocol.c and silcd/protocol.c.
1599 * Do not cache anymore the server's public key during SKE.
1600 We do mutual authentication so the proof of posession of
1601 private key is done, and if the server is authenticated in
1602 conn auth protocol with public key we must have the public
1603 key already. Affected file silcd/protocol.c.
1605 * Added new global debug variable: silc_debug_hexdump. If
1606 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1607 file lib/silcutil/silclog.[ch].
1609 * Fixed compilation warning due to char * -> const char *.
1610 Affected files lib/silcutil/silcnet.h, and
1611 lib/silccore/silcauth.[ch].
1613 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Fixed CMODE command when new channel key was created. If
1616 the creation failed the old key was removed. Next time giving
1617 same command would crash the server since the old key was
1618 freed already. Affected file silcd/command.c.
1620 * Fixed the silc_server_announce_get_channels to not crash
1621 on reconnect. Affected file silcd/server.c.
1623 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Added silc_log_set_debug_string function to set a regex
1626 string to match for debug output. Only the function names,
1627 or filenames matching the given debug string is actually
1628 printed. This way it is possible to filter out those debug
1629 strings that user is not interested in.
1631 Fixed a bug in silc_string_regexify.
1633 Affected files lib/silcutil/silclog.[ch], and
1634 lib/silcutil/unix/silcunixutil.c.
1636 * Changed the -d options in both server and Irssi SILC client
1637 to take the debug string as argument. Affected files
1638 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1640 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Added silc_hash_babbleprint to create a Bubble Babble
1643 Encoded fingerprint. The encoding is developed by Antti
1644 Huima (draft-huima-babble-01.txt), and it creates human
1645 readable strings out of binary data. Affected file
1646 lib/silccrypt/silchash.[ch].
1648 * Print the babble print now in addition of fingerprint as well
1649 in Irssi SILC client. Affected files are
1650 irssi/src/fe-common/silc/module-formats.[ch],
1651 irssi/src/fe-common/silc/core/client_ops.c.
1653 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Fixed a security problem found in SKE. The initiator's
1656 public key too is now added to the HASH hash value creation
1657 which is signed by the responder to create the SIGN value.
1658 This will prevent anyone in the middle to lie to the responder
1659 about the initiator's public key. If this is done now, the
1660 man in the middle will get caught. Updated the protocol
1663 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Better installation directory handling. Configure module
1666 paths and other paths automatically to example_silc* files
1667 in doc/. A patch by toma.
1669 * Fixed compiler warning from MPI library, and from SILC RNG.
1672 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1673 It can be configured with ./configure. A patch by toma.
1675 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * Find correct make to use in prepare-clean. A patch by
1678 toma. Affected file prepare-clean.
1680 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1682 * Added irssi variables use_auto_addr, auto_bind_ip,
1683 auto_bind_port and auto_public_ip.
1685 * Changed the interface for silc_client_send_key_agreement
1686 in lib/silcclient/silcapi.h
1690 irssi/src/silc/core/silc-core.c
1692 lib/silcclient/silcapi.h
1693 irssi/src/silc/core/silc-channels.c
1694 lib/silcclient/client_keyagr.c
1697 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Added silc_pkcs_public_key_compare to compare two
1700 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1702 * Check that the client who set the founder mode on the
1703 channel is the same client that is giving the founder
1704 mode to itself. It is done by comparing the saved public
1705 key (it is saved even in the authentication is passphrase).
1706 Affected file silcd/command.c.
1708 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Do not process packet for disconnected socket connection.

1713 * Process the DISCONNECT packet through scheduler in the
1714 client library. Affected file lib/silcclient/client.c.
1716 * Fixed the silc_client_packet_parse to not to increase
1717 the packet sequence number if the conn->sock and the
1718 current socket connection is not same. This can happen
1719 for example during key agreement when the conn includes
1720 multiple socket connections (listeners). Affected file
1721 lib/silcclient/client.c.
1723 * The sender of the file transfer request now provides also
1724 the pointer (listener) for the key exchange protocol. If
1725 the listener cannot be created then it sends empty key
1726 agreement and lets the receiver provide the listener.
1728 Added `local_ip' and `local_port' arguments to the
1729 silc_client_file_send. If they are provided they are used,
1730 if not then it will attempt to find local IP address, if
1731 not found or bind fails then the remote client will provide
1734 Affected files are lib/silcclient/client_ftp.c and
1735 lib/silcclient/silcapi.h.
1737 * Extended the FILE SEND command to support defining the
1738 local IP and port for key exchange listener. They are
1739 optional. Affected file irssi/src/silc/core/silc-servers.c.
1741 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Defined to WHOIS command reply the sending of fingerprint
1744 of the client's public key (if the proof of posession of the
1745 corresponding private key is verified by the server).
1746 Updated to the protocol specification.
1748 * Added support of receiving the client's public key's
1749 fingerprint in command reply in client library. Affected
1750 file is lib/silcclient/command_reply.c, and
1751 lib/silcclient/idlist.[ch].
1753 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Do not send over 128 chars long nickname to the server
1756 in NICK command. Affected file lib/silcclient/command.c.
1758 * Do not send over 256 chars long channel names to the server
1759 in JOIN command. Affected file lib/silcclient/command.c.
1761 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1763 * Assure that silc_server_close_connection cannot be called
1764 twice for same socket context. Affected file is
1767 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1769 * Send error message to application if opening file for
1770 writing during file transfer fails. Affected file is
1771 lib/silcclient/client_ftp.c.
1773 Remove all file transfer sessions for a client that we're
1774 removing from ID cache.
1776 Affected file is lib/silcclient/client_ftp.c.
1778 * Fixed silc_net_addr2bin to return correct address. Affected
1779 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1781 * Fixed file transfer session removing on signoff notify.
1782 Affected file irssi/src/silc/core/silc-servers.c.
1784 * Added the SilcClientFileError to be returned in the monitor
1785 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1786 Affected file lib/silcclient/silcapi.h.
1788 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1806 client library. Affected file lib/silcclient/client_prvmsg.c.
1808 * Do not actually remove the client directly from ID cache
1809 during SERVER_SIGNOFF, but invalidate it. This way we
1810 preserve the WHOWAS info for the client. Affected file
1811 silcd/server_util.c.
1813 * Fixed SERVER_SIGNOFF notify handling in the server. The
1814 server is now able to process incoming SERVER_SIGNOFF notify
1815 for a server that it doesn't even know about. It will remove
1816 the clients provided in the notify. Affected file
1817 silcd/packet_receive.c.
1819 * Check for partial packet in data queue after every packet that
1820 was found from the queue. Return and wait for more data if
1821 there is partial data in queue. Affected file is
1822 lib/silccore/silcpacket.c.
1824 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added SilcClietFileError enum to indicate error in
1827 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1828 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1829 Affected files lib/silcclient/silcapi.h and
1830 lib/silcclient/client_ftp.c.
1832 * Check that newsize in silc_buffer_realloc is larger than
1833 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1835 * Added better monitor of file transfers. It now monitors
1836 key agreement protocol during the file transfer too. Added
1837 error reporting too. Affected files
1838 irssi/src/silc/core/silc-servers.c,
1839 irssi/src/fe-common/silc/module-formats.[ch].
1841 * Wrote a help file for FILE command.
1843 * Added silc_rng_global_get_byte_fast to get not-so-secure
1844 random data as fast as possible. Random data is read from
1845 /dev/urandom if available and from the SILC RNG if not
1846 available. It is used in padding generation. Affected file
1847 lib/silccrypt/silcrng.[ch].
1849 * All packets in client library are now processed synchronously.
1850 Optimized packet processing a lot. Affected file
1851 lib/silcclient/client.c.
1853 * All server connection packets are processing synchronously
1854 now in server, to optimize packet processing. Affected file
1857 * Include files are installed now only in Toolkit distribution
1858 if make install is given. Affected files: all Makefile.am's.
1860 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Assure that silc_client_notify_by_server_resolve does not
1863 resolve the client information multiple times. If it cannot
1864 be found by the first it cannot be found at all. Affected
1865 file lib/silcclient/client_notify.c.
1867 * Fixed WHOWAS command reply calling. Affected file
1868 lib/silcclient/command_reply.c.
1870 * Removed all references to silc_idlist_get_client from the
1871 Irssi SILC client since that call is internal call used by
1872 the library. The Irssi SILC client will use now client
1873 retrieval functions found in silcapi.h.
1875 * Fixed a bug in resolving nickname info before sending
1876 private message. It used freed memory. Affected file
1877 irssi/src/silc/core/silc-servers.c.
1879 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Assure my_channels statistics cannot go negative in server.
1882 Affected files silcd/server.c, silcd/server_util.c.

1898 * Added silc_net_localip to return local host's IP address.
1899 Affected file lib/silcutil/silcnet.[ch].
1901 * If key exchange or rekey protocol is active for a connection
1902 parse all packets syncronously since there might be packets
1903 in packet queue that we are not able to process without first
1904 processing packets before them. Affected file silcd/server,
1905 lib/silcclient/client.c.
1907 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1908 whether library should continue processing the packet.
1909 Affected file lib/silccore/silcpacket.h.
1911 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1912 SilcSFTPMonitorData to SFTP server to monitor various
1913 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1953 lib/silcclient/idlist.h.
1955 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1956 is incomplete and is being resolved, it won't be resolved
1959 Make sure also that USERS command reply does not resolve
1960 twice information. Affected file is
1961 lib/silcclient/command_reply.c.
1963 Make sure that silc_client_get_clients_by_list does not
1964 resolve twice same information.
1966 * Check for valid client->id in the silc_server_free_client_data.
1967 Affected file silcd/server.c.
1969 * Fixed /GETKEY nick@server not to crash if the server entry
1970 is not found. Affected file lib/silcclient/command.c.
1972 * Fixed the silc_server_check_cmode_rights to check the
1973 requested modes correctly. Affected file silcd/command.c.
1975 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>

1978 Affected file silcd/command.c.
1980 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Call the silc_server_udpate_servers_by_server in the
1983 primary router that comes back online in the backup resuming
1984 protocol. Otherwise it routes packets wrong. Affected file
1985 silcd/server_util.[ch], silcd/server_backup.c.
1987 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1990 lib/silcutil/silcbuffmt.[ch].
1992 * Redefined the SILC packet header to include the padding
1993 length. Affected file lib/silccore/silcpacket.[ch].
1995 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1996 length for maximum padding up to 128 bytes). Affected
1997 file lib/silccore/silcpacket.h.
1999 * Removed all backwards support for old 0.5.x MAC thingies.
2000 The SILC packet header change makes it impossible to be
2001 backwards compatible.
2003 * Send the ENDING packet with timeout in the backup resuming
2004 protocol. This is to assure that all routers has connected
2005 to the primary router. Affected file silcd/server_backup.c.
2007 * Changed the RNG to take the first IV from random data. It
2008 used to take it from zero actually. Changed the RNG also
2009 to use /dev/urandom during session. /dev/random is used
2010 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2012 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2014 * Changed the SILC packet header to have the first two bytes
2015 (the packet length) encrypted. Affected files aroung the
2016 code tree, lib/silccore/silcpacket.[ch]. Removed the
2017 SilcPacketCheckDecrypt callback. It is not needed anymore
2018 since the silc_packet_receive_process will determine now
2019 whether the packet is normal or special.
2021 * Implemented the unidirectional MAC keys. Affected files
2022 lib/silcske/silcske.c, silcd/protocol.c and
2023 lib/silcclient/protocol.c.

2030 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Allow backup router to announce servers. All servers
2033 announced by backup router are added to the global list
2034 automatically. Update hte server's socket to our primary
2035 router also when backup router announces a server.
2036 Affected file silcd/packet_receive.c.
2038 * Do not update the client->router in the function
2039 silc_server_udpate_clients_by_server if the client is on
2040 global list. We might fail to find any specific server
2041 for locally connected clients and local cell clients. They
2042 should still use the `from' and not `to' as client->router.
2043 This fixes backup router resuming protocol. Affected file
2044 silcd/server_util.c.
2046 * Decrease channel statistics count only if the channel
2047 deletion worked. Affected files are silcd/server.c and
2048 silcd/server_util.c.
2050 * Added silc_server_update_servers_by_server to update origin
2051 of all server entries. Used during backup router protocol.
2052 Affected files silcd/server_util.[ch], silcd/server.c. and
2053 silcd/backup_router.c.
2055 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2056 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2057 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2058 lib/silccrypt/silchmac.c.
2060 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Assure that router cannot reroute the same channel message
2063 to the sender. Affected file silcd/packet_receive.c.
2065 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Made better checks that the channel message is not sent
2068 to the router it came from. Affected file is
2069 silcd/packet_send.c. Fixed memory leak too.
2071 * Announce informations for incoming router connection, but
2072 only after checking if it is replaced by backup router.
2073 Affected file silcd/packet_receive.c.
2075 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Fixed the backup resuming protocol to work in multiple
2078 router environment. Affected file silcd/server_backup.c.
2080 * Route packet only to one router in the function
2081 silc_server_packet_send_to_channel. Affected file is
2082 silcd/packet_send.c.
2084 * Fixed silc_server_send_notify_dest to set the broadcast
2085 flag. Fixed the silc_server_send_notify_topic to actually
2086 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2087 Affected file silcd/packet_send.c.
2089 * Changed the SFTP Filesystem interface. Changed the
2090 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2091 the filesystem operation function. The SilcSFTPFilesystem
2092 is now a context that is allocated by all filesystem allocation
2093 functions and it already includes the operations structure
2094 and filesystem specific context. It is given as argument
2095 now to the silc_sftp_server_start. This made the interface
2096 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2097 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2099 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Changed the backup router adding and getting interfaces
2102 in the server. The router that will be replaced by the
2103 specified backup router is now sent as argument. Affected
2104 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2107 * Added silc_net_addr2bin_ne to return the binary form of
2108 the IP address in network byte order. Affected files
2109 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2111 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2113 * Check for existing server ID in silc_server_new_server
2114 and in silc_server_connect_to_router_final and remove the
2115 old entry if it exists. Affected file silcd/packet_receive.c,
2118 * Send the channel message always to only one router, either
2119 in upstream or downstream. Affected file is
2120 silcd/packet_send.c.
2122 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2124 * Wrote the definition of the backup resuming protocol to the
2125 protocol specification.
2127 * Removed one redundant channel key generation from normal
2128 server during joining procedure. Removed one redundant
2129 channel key sending from server to router during joining
2130 procedure. Affected file silcd/command.c.
2132 * Made minor bugfixes to the backup router resuming protocol.
2133 Affected file silcd/server_backup.c, server.c.
2135 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Added --disable-asm configuration option. Affected files
2138 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2141 * Implemented the backup resuming protocol that is used to
2142 resume the primary router position in the cell after the
2143 primary router comes back online. Affected files
2144 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2145 and silcd/server_util.[ch].
2147 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Sleep two (2) seconds after sending QUIT command to server.
2150 Affected file lib/silcclient/command.c.
2152 * Assure that if outgoing data buffer is pending do not force
2153 send any data. Affected file silcd/packet_send.c.
2155 * Assure that if outgoing data buffer is pending do not force
2156 send any data. Affected file lib/silcclient/client.c.
2158 * Implemented the backup router support when the primary router
2159 goes down. The servers and routers can now use the backup
2160 router as new primary router without loosing connectivity.
2162 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2164 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2165 in the server to indicate disabled entry. All data read
2166 from the connection will be ignored and no data is sent
2167 for entry that is disabled. Affected files are
2168 silcd/idlist.h, silcd/server.c.
2170 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Created SFTP client and server test programs in the
2173 lib/silcsftp/tests directory.
2175 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * Implemented memory filesystem (virtual filesystem) for
2178 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2181 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Implemented the SFTP (SSH File Transfer Protocol) to the
2184 lib/silcsftp. It includes SFTP client and SFTP server
2187 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Moved lib/silccore/silcprotocol.[ch] to the
2190 lib/silcutil library.
2192 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2193 take variable argument list pointer as argument. Affected
2194 file lib/silcutil/silcbuffmt.[ch].
2196 * Added silc_buffer_set function that is used to set data
2197 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2198 Affected file lib/silcutil/silcbuffer.h.
2200 * Changed various routines in the core library to use the new
2201 silc_buffer_set instead of allocating new buffer only for
2204 * Added 64-bit value formatting and unformatting support to the
2205 silc_buffer_[un]format routines. Affected file is
2206 lib/silcutil/silcbuffmt.[ch].
2208 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2209 to includes/bitmove.h.
2211 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Fixed channel user mode saving in client library. Affected
2214 file lib/silcclient/command[_reply].c.
2216 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Defined the file transfer to the SILC Protocol. Added
2219 new packet type SILC_PACKET_FTP and defined File Transfer
2220 Payload. The mandatory file transfer protocol is SFTP
2221 (SSH File Transfer Protocol). Affected file in addition
2222 of the internet draft is lib/silccore/silcpacket.h.
2224 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2225 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2226 is used as part of backup router protocol when the primary
2227 router of the cell is back online and wishes to resume
2228 the position as primary router.
2230 * Redefined the MAC generation keys in the protocol. The
2231 same key is not used anymore in both direction. Both
2232 direction will now use different keys for sending and
2233 receiving. This fixes a potential security flaw. This
2234 change causes incompatibilities in the protocol.
2236 * Redefined also the MAC computation from the packet.
2237 An packet sequence number is now added to the MAC
2238 computation. This prevents possible replay attacks against
2239 the protocol. This change too causes incompatibilities
2242 Added `sequence' field to the SilcPacketContext to hold
2243 the current sequence number for the packet.
2245 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Added `created' field to the SilcIDListData in the file
2248 silcd/idlist.h to indicate the time when the entry was
2251 * Added `created' field to the SilcChannelEntry too. Affected
2252 file silcd/idlist.h.
2254 * Added `creation_time' aguments to all the announcement functions
2255 in the server. If it is provided then only the entries that
2256 was created after the provided time frame are actually
2257 announced. Affected file silcd/server.[ch].
2259 * The protocol says that the Channel ID's IP address must be
2260 based on the router's IP address. Added check for this in
2261 the silc_server_new_channel when processing incoming New Channel
2262 Payload. Affected file silcd/packet_receive.c.
2264 * Print out the correct version with --version in SILC client.
2265 Affected file irssi/src/silc/core/silc-core.c.
2267 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Fixed WHOWAS command to check for completnes of the client
2270 entry always, not just when the command is coming from client.
2271 Affected file silcd/command.c.
2273 * Added new function silc_server_packet_queue_purge to purge the
2274 outgoing data queue to the network. After the function returns
2275 it is guaranteed that the outgoing packet queue is empty.
2276 Affected file silcd/packet_send.[ch].
2278 * Purge the outgoing packet queue in the rekey protocol's final
2279 callback to assure that all rekey packets go to the network
2280 before quitting the protocol. Affected file silcd/server.c.
2282 * Added silc_client_packet_queue_parse as similar function as
2283 in server to the client library. The affected file is
2284 lib/silcclient/client.c.
2286 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Splitted silcd/server.c and created silcd/server_util.[ch]
2289 for utility functions.
2291 * Added new socket flag SILC_SF_DISABLED to indicate that the
2292 connection is open but nothing can be sent to or received from
2293 the connection. Affected file lib/silcutil/silsockconn.[ch].
2294 The checking for disabled socket is checked in the low level
2295 silc_socket_write and silc_socket_read functions.
2297 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Allow only nicknames and channel names that fits into the
2300 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2302 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * When processing JOIN command reply in server check that if
2305 the channel exists in our global list we'll move it the local
2306 list. Affected file silcd/command_reply.c.
2308 * Fixed the check whether client is joined on the channel already
2309 in JOIN command. Affected file lib/silcclient/command.c.
2311 * Fixed the JOIN command reply to check whether the channel
2312 already exists. Affected file lib/silcclient/command_reply.c.
2314 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2316 * Added silc_ske_status_string to map the SKE error numbers
2317 to readable strings. The affected files are
2318 lib/silcske/silcske[_status].[ch].
2320 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Do not show the private channels on the WHOIS channel list
2323 as it is not allowed by the protocol. The affected file is
2326 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Assure that the packet length digged from the actual packet
2329 is something sensible in the silc_packet_decrypt_rest_special
2330 in lib/silccrypt/silcpacket.c.
2332 * Free and NULL the allocated pointer in silc_hmac_alloc if
2333 the HMAC allocation fails. The affected file is
2334 lib/silccrypt/silchmac.c.
2336 * Print the selected security properties to the log files in
2337 the server. Affected file silcd/protocol.c.
2339 * Add SKE's reference counter even if calling the completion
2340 callback manually. Otherwise it goes negative, although it
2341 does not cause any problems. The affected file is
2342 lib/silcske/silcske.c.
2344 * Remove the client entry with short timeout after giving the
2345 KILL command. Affected file lib/silcclient/command.c.
2347 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2348 case all found clients are already disconnected (WHOWAS would
2349 found them) in the server. Affected file silcd/command.c.
2351 * Update the last_receive (time of last data received) to be
2352 updated only when received private or channel message so that
2353 the idle time showed in WHOIS makes more sense.
2355 * Added boolean field `valid' in to the SilcClientEntry in the
2356 client library to indicate whether the entry is valid or not.
2357 This fixes the nickname change bug on channel when changing
2358 the nickname to be same than the old (like nick to Nick) the
2359 nickname formatter doesn't set the new nick anymore to Nick@host.
2360 Affected file lib/silcclient/idlist.[ch].
2362 * Now actually fixed the nickname changing on disconnection.
2363 Added new function silc_change_nick to the Irssi SILC Client.
2364 Affected file irssi/src/silc/core/client_ops.c,
2365 irssi/src/silc/core/silc-nicklist.[ch].
2367 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Check that the public key exists in the GETKEY command before
2370 trying to encode it. Affected file silcd/command.c.
2372 * Print some notifications on received public keys with GETKEY
2373 command in the Irssi SILC Client. Affected files are
2374 irssi/src/fe-common/silc/module-formats.[ch],
2375 irssi/src/silc/core/client_ops.c.
2377 * Use IDENTIFY command to resolve the server information in the
2378 GETKEY command instead of INFO command. Affected file
2379 lib/silcclient/command.c.
2381 * All command reply functions in the client library now calls
2382 the pending command reply callbacks even if an error has
2383 occurred. The server has done this a long time and now it was
2384 time to move the client library to this as well. Now all
2385 errors can be delivered back to the pending command reply
2386 callbacks if necessary. Affected files are
2387 lib/silcclient/command[_reply].[ch].
2389 * Change the nickname on disconnection back to the username
2390 because in reconnect the server will enforce it to it anyway.
2391 Affected file irssi/src/silc/core/silc-servers.c.
2393 * Fixed a config file parsing bug in the Irssi SILC client.
2394 Affected file irssi/src/silc/core/clientconfig.c.
2396 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * When printing the channel mode on JOIN, verify that the
2399 channel key and channel's HMAC are valid. Affected file
2400 irssi/src/silc/core/client_ops.c.
2402 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2405 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2406 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2408 * Removed channel key rekey task deleting from the function
2409 silc_server_save_channel_key. Affected file silcd/server.c.
2410 Added explicit timeout task context instead that is used to
2411 delete the task if we are registering a new task before the
2412 new task has elapsed.
2414 * When channel key rekey occurs the client library now saves
2415 the old channel key for a short period of time (10 seconds) and
2416 is able to use it in case some is still sending channel
2417 messages encrypted with the old key after the rekey. Affected
2418 file lib/silcclient/[idlist.h|client_channel.c].
2420 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Added check to the silc_server_new_id_real to not accept
2423 new ID if it is the sender's own ID. Affected file is
2424 silcd/packet_receive.c.
2426 * Assure that we do not announce ourself or the one we've
2427 sending our announcements when we're router and are announcing
2428 servers to our primary router. Affected file silcd/server.c.
2430 * Fixed silc_server_command_identify_check_client to assemble
2431 correct WHOIS packet. It send corrupted WHOIS packet and
2432 caused problem with router to router connections. Affected
2433 file silcd/command.c.
2435 Fixed also silc_server_command_whois_check the same way
2436 as for the IDENTIFY command.
2438 * Added new SilcIDListStatus to the server in the SilcIDListData
2439 structure. The status now includes the current status of
2440 the entry (like registered, resolved etc.). Affected file
2441 silcd/idlist.[ch]. Defined a bunch of different status types
2442 as well. This replaced the old boolean registered field as well.
2444 Added resolve_cmd_ident field to the SilcClientEntry structure
2445 too so that if the entry is for example being resolved so
2446 another command may attach to the same pending command reply
2447 without requiring to resolve the same entry again. This concept
2448 should optimize the WHOIS and the IDENTIFY resolving under
2449 heavy load by taking away unnecessary resolving for entries
2450 that are being resolved already.
2452 Added support for adding multiple pending commands for one
2453 command idenfier. Affected file silcd/command[_reply].[ch].
2455 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2456 before deleting the data. Otherwise the hash table will have
2457 freed data in comparison functions. Affected file is
2458 silcd/command_reply.c.
2460 * Fixed silc_idlist_replace_client_id to add the new entry to
2461 the cache with NULL nickname. Otherwise there will be invalid
2462 memory as the nickname after the nickname is freed. Affected
2463 file silcd/packet_receive.c.
2465 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2466 saved into wrong slots because the previous number of entries
2467 was not taken into account. Affected file silcd/idlist.c.
2468 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2470 * If we are router and we receive JOIN notify to a channel that
2471 does not have any users then notified client is marked as the
2472 channel founder, as it is it. The affected file is
2473 silcd/packet_receive.c
2475 * Added to the extended hash table API's table_del_*ext functions
2476 the destructor as argument too, so that the caller can decide
2477 which destructor to use or whether to use destructor at all.
2478 Affected file lib/silcutil/silchashtable.[ch].
2480 * Fixed ID Cache purging. It actually deleted the entries from
2481 the hash table after the data was freed. The hash table ended
2482 up comparing freed memory. The affected file is
2483 lib/silccore/silcidcache.c.
2485 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Fixed Irssi SILC client's KILL command's HELP syntax.
2489 * The USERS command now resolves the detailed user information
2490 if the userinfo field is missing. Affected file is
2491 lib/silcclient/command_reply.c.
2493 * Do not print error in silc_file_read if the read file does
2494 not exist. Just silently return NULL. Affected file is
2495 lib/silcutil/silcutil.c.
2497 * Fixed the silc_log_output to not wine about NULL filename
2498 and to not create some bogus " " filename. Affected file is
2499 lib/silcutil/silclog.c.
2501 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Fixed various printing bugs on the user interface in the
2504 Irssi SILC Client. Minor changes that were forgotten from
2507 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Fixed the configure.in.pre and the compilation and distribution
2510 environment to support the new autoconf 2.52. That version is
2511 now required to compile the CVS trunk.
2513 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2516 to generally parse user@fqdn format strings. Affected file
2517 lib/silcutil/silcutil.c.
2519 * Added nickname_format and nickname_force_format fields to the
2520 SilcClientParams structure. The first one defines the format
2521 for the nicknames that the library will enforce if the receives
2522 multiple same nicknames. The second one is boolean value and
2523 can be used to force the library to always enforce the format
2524 to the nicknames regardles whether there are multiple nicknames
2525 or not. This configurable formatting was employed to flexibly
2526 support accessing multiple nicknames from the user interface.
2527 The userinterface can now set the nicknames to what ever format
2528 they prefer. Affected file lib/silcclient/silcapi.h.
2530 Added function silc_client_nickname_format to the file
2531 lib/silcclient/idlist.c. It performs the nickname formatting.
2533 Added new field `hostname´ to the SilcClientEntry context.
2534 It holds the hostname of the client. Affected file is
2535 lib/silcclient/idlist.h.
2537 * Irssi SILC Client sets the nicknames in nick@hostn format.
2538 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2539 irssi/src/silc/core/silc-core.c.
2541 The WHOIS printing now also shows both the real nickname and
2542 the formatted nickname so that user knows how to access the
2543 user if there are multiple same nicknames cached. Affected
2544 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2545 printing formatting too to take the hostname now as a separate
2546 argument. The Affected file is
2547 irssi/src/fe-common/silc/modules-formats.[ch].
2549 * Changed the silc_client_get_clients_local to accept the formatted
2550 nickname as argument. It accepts the real nickname too but the
2551 formatted nickname can be used to find the true entry from
2552 multiple entries. Affected file lib/silcclient/silcapi.h and
2553 lib/silcclient/idlist.c.
2555 * Added nickname_format_parse field to the SilcClientParams.
2556 It is a callback function provided by the application to parse
2557 the nickname out of the formatted nickname string. The library
2558 calls it to get the nickname from the formatted string. Since
2559 the application generally knows better the format of the nickname
2560 string it parses it instead of the library, even though library
2561 encodes the formatted string. If the callback function is not
2562 provided then the library will use the string as is. The
2563 affected file is lib/silcclient/silcapi.h.
2565 * All the nickname strings passed to the client library in
2566 commands are now expected to be formatted nickname strings.
2567 If the command does not support the formatted nickname string
2568 it will assume that the sent string is the actual nickname.
2569 Affected file lib/silcclient/command.c.
2571 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Added public key authentication support to OPER and SILCOPER
2574 commands in the client library. Affected file is
2575 lib/silcclient/command.c.
2577 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Changed the get_auth_methdod client operation to be asynchronous.
2580 It can be async if the application resolves the authentication
2581 method from the server during the negotiation. Added new
2582 SilcGetAuthMeth completion callback that the application will
2583 call after resolving the authentication method.
2585 Added function silc_client_request_authentication_method that
2586 the application can use to resolve the authentication method
2587 from the server. Added also SilcConnectionAuthRequest callback
2588 that the library will call after the server has replied. The
2589 application can call this function if it does not know the
2590 current authentication method.
2592 Affected files are lib/silcclient/client.c and
2593 lib/silcclient/silcapi.h.
2595 * The Irssi SILC client now automatically resolves the authentication
2596 method incase any configuration information is not present (and
2597 currently there never is). The affected file is
2598 irssi/src/silc/core/client_ops.c.
2600 * Fixed public key authentication from the client library.
2601 Affected file lib/silcclient/protocol.c. Changed also the
2602 protocol specification about the public key authentication in
2603 the connection authentication protocol. The actual data to be
2604 signed is now computed with a hash function before signing.
2606 * Fixed the public key authentication from the server as well.
2607 Affected file silcd/protocol.c.
2609 * Removed the mlock()'s from the memory allocation routines.
2610 Affected file lib/silcutil/silcmemory.c. The ./configure does
2611 not check anymore for the mlock(). Affected file is
2614 * Fixed USERS command in server to allow the execution of the
2615 command for private and secret channels if the client sending
2616 the command is on the channel. Affected file silcd/command.c.
2618 * Fixed silc_client_get_clients_local to return the clients
2619 count correctly. It could return wrong value. Affected file
2620 lib/silcclient/idlist.c.
2622 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2625 types. The assembler optimizations seemed not to like 64-bit
2626 data types. The assmebler optimizations thus are now enabled
2627 also for BSD systems as opposed to only enable them for Linux.
2629 * Do not check for threads at all on BSD systems. Affected
2630 file configure.in.pre.
2632 * Removed -n and -h options from the Irssi SILC Client since
2633 they are not used in silc.
2635 * Fixed the prime generation to assure that the first digit
2636 of the generated random number is not zero since our conversion
2637 routines does not like number strings that starts with zero
2638 digit. If zero digit is seen the random number is regenerated.
2639 This caused some corrupted RSA keys when the zero first digit
2640 was met. Affected file lib/silcmath/silcprimegen.c.
2642 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2644 * Fixed WIN32 configuration in the ./configure script.
2645 Fixed to include xti.h on environments that has it.
2646 Patches by Carsten Ilchmann and andrew.
2648 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Changed the silc_id_create_client_id to be collision
2651 resistant. It is now assured that there cannot be created
2652 two same client ID's. I suspect that some weird bugs in
2653 the server were actually caused by duplicate Client IDs.
2654 Affected file silcd/serverid.[ch]. A router receiving
2655 new ID now also assures and informs the sending server
2656 if the ID caused collision.
2658 * Changed the silc_id_create_channel_id to also assure that
2659 there are no collisions.
2661 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Statement about ignoring the Mutual Authentication flag when
2664 performing rekey with PFS was a bit misleading. It is ignored
2665 if it was set in the initial negotiation, it cannot be even
2666 set in the rekey. Fixed in the ke-auth draft. Started the
2667 new versions of the protocol drafts in the doc/.
2669 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Fixed a bug in silc_client_command_identify_save when saving
2672 new channel information. The channel name was no duplicated
2673 and caused crash on exit. Affected file is
2674 lib/silcclient/command_reply.c.
2676 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed the getkey command handling in the server. Send just
2679 empty OK reply to the sender if the key could not be fetched
2680 (but everything else was ok, like the key just was not available).
2681 Changed the public key parameter to optional in the protocol
2682 specs so that empty OK reply can be sent. Affected file
2685 Added a message to Irssi SILC client to tell to user if the
2686 server did not return a public key.
2688 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Fixed a channel key regeneration bug. It registered new
2691 timeout tasks exponentially until all system resources were
2692 used. Affected file silcd/server.c.
2694 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Added the SILC Document generator to the scripts/silcdoc.
2697 It can be used to generate the Toolkit Reference Manual out
2698 of the source tree. Internally it will also use the RoboDoc
2699 generator now imported in util/robodoc.
2701 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Added couple of return's in rekey protocol if error orccurred
2704 during the protocol. The execution must be terminated.
2705 Affected file silcd/protocol.c. Also, terminate the protocol
2706 always with timeout.
2708 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * The client's Client ID was created initally from the wrong
2711 nickname (it could have been in format nick@host) in the
2712 silc_server_new_client. Affected file silcd/packet_receive.c
2714 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Added some SILC_LOG_ERROR's to various error conditions
2717 if client could not be added to ID cache. Affected files
2718 silcd/packet_receive.c and silcd/server.c.
2720 * When client's sock->user_data is freed, NULL also the
2721 client->router and client->connection pointers. Added check
2722 for these pointers being NULL to various places around the
2723 code. Affected file silcd/server.c.
2725 * Added client->data.registered == TRUE checks to various
2726 places around the code to assure that unregistered client's
2727 are not handled when it is not allowed. Affected file
2730 * Added `bool registered' fields to all
2731 silc_idlist_[server|client]_get_* routines to indicate whether
2732 the fetched client needs to be registered or not. Affected
2733 file silcd/idlist.[ch].
2735 * Add your own entry as registered to the ID cache in the
2736 server. Affected file server.c.
2738 * Fixed a bug in silc_server_new_server. The SilcServer was
2739 set as the new server's context instead of SilcServerEntry.
2740 This naturally caused some weird bugs.
2742 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2744 * Do not delete the channel rekey task when adding it
2745 for in silc_server_create_channel_key.
2747 * Changed the silc_server_create_channel_key to return
2748 TRUE or FALSE to indicate the success of the channel key
2751 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Fixed MSVC++ project files and added missing files to
2754 Makefiles under win32/.
2756 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Do not add TCP_NODELAY flag if the operating system
2759 does not have it defined. Affected files are
2760 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2762 * Fixed buffer overflow from Irssi SILC Client. Affected
2763 file irssi/src/fe-common/core/themes.c.
2765 * Fixed double free in client library in the file
2766 lib/silcclient/client.c when disconnecting from server.
2768 * Applied double free patch from cras to Irssi SILC client.
2769 Affected files irssi/src/core/[modules/expandos].c
2771 * Fixed the disconnection handling to Irssi SILC Client.
2772 The application must call silc_client_close_connection
2773 in ops->connect client operation in case of failure of
2774 the connection. Affected file is
2775 irssi/src/silc/core/client_ops.c.
2777 * Do not set sock->protocol to NULL in the function
2778 silc_client_close_connection after executing the protocol's
2779 final callback since the sock might not be valid anymore.
2780 Affected file lib/silcclient/client.c.
2782 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2784 * Do not enable SILC_THREADS if the linking with libpthread
2785 did not happen. Affected file configure.in.pre.
2787 * Added notion to protocol specification that server must
2788 verify the sent authentication payload with CMODE when
2789 setting the channel founder key. Implemented it to the
2790 server. Affected file silcd/command.c.
2792 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Added _EXTRA_DIST SILC distribution variable to the
2795 distributions file. It is used to conditionally add extra
2796 files or directories to the specific distribution. Affected
2797 files ./prepare, Makefile.am.pre and distributions.
2799 Removed the `_' from the start of the distribution names.
2802 * Added README.WIN32 for instructions to compile the Toolkit
2805 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Fixed a double free in disconnection in the server. Affected
2808 file is silcd/server.c.
2810 * Fixed the lib/silcske/groups.c to work now also with GMP
2811 MP library. The string conversion did not work when using
2812 specific base and the base is indicated in the string as well.
2814 * Created win32/ directory which now includes MSVC++ specific
2815 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2816 It will appear only in the toolkit distribution
2818 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Changed the key material distribution function in case when
2821 the hash output is too short. The data is now concatenated
2822 a bit differently than it used to. Made the change to the
2823 SKE protocol specification.
2825 * Added better GMP detection to configure.in.pre. A patch
2828 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2830 * Fixed a minor bug in SKE that might cause some problem on
2831 some platforms. Affected file lib/silcske/silcske.c.
2833 * Added the cookie checking for initiator in the SKE. It checks
2834 that the responder returns the sent cookie unmodified. The
2835 affected file is lib/silcske/silcske.c. Added new SKE
2836 error type INVALID_COOKIE that can be sent during the
2837 negotiation. Fixed some memory leaks as well.
2839 * Added the "invalid cookie" error message to Irssi SILC client's
2842 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Added `task_max' field to the SilcClientParams to indicate
2845 the maximum tasks the scheduler can handle. If set to zero,
2846 default values are used. Affected file lib/silcclient/silcapi.h.
2848 * Fixed memory leaks in silc_client_close_connection. Affected
2849 file lib/silcclient/client.c.
2851 * Added silc_client_del_client_entry to client library to free
2852 all memory of given client entry. Affected file is
2853 lib/silcclient/idlist.[ch].
2855 * Added new functions silc_client_del_channel and
2856 silc_client_del_server to delete channel and server entries.
2857 Affected file lib/silcclient/[silcapi.h/idlist.c].
2859 * Removed silc_client_del_client_by_id from silcapi.h.
2861 * Fixed the INFO command to return the server's own info
2862 correctly when querying by Server ID. Affected file is
2865 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Removed the non-blocking settings in WIN32 code in the
2868 silc_sock_[read/write] and added SleepEx instead. Affected
2869 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2870 of input data is now checked with FIONREAD and ioctlsocket.
2872 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Call silc_schedule_task_del_by_context in the
2875 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2876 Affected file lib/silccore/silcprotocol.c.
2878 * Call silc_protocol_cancel for active protocols in the
2879 silc_server_close_connection if the funtion
2880 silc_server_free_sock_user_data has not been called.
2881 Affected file silcd/server.c.
2883 * Generic tasks cannot be deleted using the del_by_fd
2884 task deleting function since generic tasks does not match
2885 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2887 * Added a notion to SILCOPER help file that the SILCOPER works
2888 only on router server, not on normal server.
2890 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Added for WIN32 support for the new scheduler as well.
2893 Affected file lib/silcutil/win32/silcwin32schedule.c.
2895 * Fixed the SHA1 implementation to work on various platforms.
2897 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2900 API. It is part of the scheduler now. Everything else is
2901 as previously but some functions has changed their names.
2902 Checkout the lib/silcutil/silcschedule.h for the interface.
2903 Updated all applications to use the new interface. Affected
2904 files are lib/silcutil/silcschedule.[ch].
2906 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Found a bug in the SKE implementation. The HASH value,
2909 specified by the protocol, was not computed correctly. The
2910 public key of the responder was not added to the computation
2911 even though it is mandatory. Affected file lib/silcske/silcske.c.
2912 This unfortunately causes incompatibilities with older
2913 clients and servers.
2915 * Added WIN32 specific network init and uninit functions:
2916 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2917 the Winsock2. Affected file lib/silcutil/silcnet.h and
2918 lib/silcutil/win32/silcwin32net.c.
2920 * Set the socket always to nonblocking mode on WIN32 after
2921 reading data or writing data. Affected file is
2922 lib/silcutil/win32/silcwin32sockconn.c.
2924 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Fixed various compilation problems under WIN32. Affected
2927 files lib/silcutil/win32/silcwin32thread.c and
2928 lib/silcutil/win32/silcwin32schedule.c.
2930 * Removed all _internal.h #includes from public header
2931 files. Internal headers must never be included from
2934 Removed also the lib/silcske/payload_internal.h file.
2936 * All include files that may be needed (public and some others
2937 included by the public headers) by application developers are
2938 now copied to the ./includes directory. It does not copy any
2939 internal headers. Affected file Makefile.defines.pre and all
2940 Makefile.am's under lib/ and subdirs.
2942 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Do not change the ~/.silc directory's permissions automatically.
2945 Affected file irssi/src/silc/core/clientutil.c.
2947 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2949 * Do not cancel the protocol in silc_server_close_connection
2950 it might cause recursion. Now cancelled in the function
2951 silc_server_free_sock_user_data. Affected file silcd/server.c.
2953 * Fixed the silc_server_remove_clients_by_server to regenerate
2954 the channel keys correctly finally. Added also new function
2955 silc_server_remove_clients_channels to actually do it.
2956 Affected file silcd/server.c.
2958 * Fixed the silc_server_new_channel to not crash by giving
2959 wrong router to the new channel. Affected file is
2960 silcd/packet_receive.c.
2962 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2965 which is given as argument to the silc_client_alloc now.
2966 It can be used to configure the client and set various parameters
2967 that affect the function of the client.
2969 * The USERS command in server did not check whether the channel
2970 is private or secret. Affected file silcd/command.c.
2972 * Added new argument to the USERS command in protocol specification.
2973 The USERS command now can take the channel name as argument
2974 as well. Added support for this in client and server and
2975 updated the protocol specs.
2977 * Completed the GETKEY command in client. It can be now used
2978 to fetch also servers public key not only some clients.
2979 Affected files lib/silcclient/command[_reply].c.
2981 * Added silc_client_get_server to return server entry by the
2982 server name. Affected files lib/silcclient/silcapi.h and
2985 * Redefined the IDENTIFY command in protocol specification to be
2986 more generic. It now can be used to query information about
2987 any entity in the SILC Network, including clients, servers and
2988 channels. The query may be based either the entity's name
2989 or the ID. Added support for this in both client and server.
2991 Affected files silcd/command.c and lib/silcclient/command.c
2992 and command_reply.c.
2994 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2995 the _from_client and _from_server functions. Affected file
2998 * Added silc_client_get_channel_by_id_resolve to the file
2999 lib/silcclient/silcapi.h to resolve channel information by
3000 its ID. Added also silc_client_get_channel_by_id that
3001 does not resolve it from the server.
3003 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Added SilcServerEntry context into the client library
3006 to represent one server. The INFO command now allocates
3007 these to save the resolved server info. For now on the
3008 client library will also keep information about servers,
3009 connected and resolved with INFO.
3011 The INFO command now allocates the SilcServerEntry context
3012 and saves the server info there. The COMMAND_REPLY in
3013 the INFO now returns the parameters to application in
3014 same order as defined in the protocol specification.
3016 The entries are cached in the client->server_cache.
3018 * The INFO command is now issued after received the Client ID
3019 from the server. Affected file lib/silcclient/client.c.
3021 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3022 to the application as the mode changer might be server.
3023 It is guaranteed that NULL is not returned anymore to the
3024 application. Affected file lib/silcclient/client_notify.c.
3026 The ID Type is now also passed to the application so that
3027 it can check whether the returned entry is SilcClientEntry
3030 Added new function silc_client_get_server_by_id to return
3031 the server entry by ID. Affected files are the
3032 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3034 * Do not create the channel in the Irssi SILC Client when issuing
3035 the JOIN command but when received the sucessful JOIN command
3036 reply. Otherwise the channel might get created even though we
3037 could not join it. The Affected file is
3038 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3040 * Fixed a channel joining bug in router. The router must also
3041 check the channel modes, invite and ban lists etc. when serving
3042 the JOIN command sent by normal server. Affected file is
3043 silcd/command.c. The router now resolves the client's
3044 information from the server who sent the JOIN command if it
3045 does not know it, and processes the JOIN command only after
3048 * Changed the SilcCommandCb to take new argument; void *context2.
3049 Affected file lib/silccore/silccommand.h
3051 The second argument in the command callbacks in the server now
3052 includes the SilcServerCommandReplyContext if the command was
3053 called as pending command callback from the command reply.
3054 Otherwise it is NULL. When called as pending the status of the
3055 command reply will be checked and if it was erronous the
3056 error will be sent to the original sender of the command.
3057 This way the client always receives the error messages even
3058 though the server was actually the one who received the error
3059 when it resent the command to router, for example. Affected
3060 files silcd/command[_reply].[ch].
3062 * Fixed sending WHOWAS command's error message to client if
3063 the requested client could not be found. It was missing.
3066 * Changed the CMODE and CUMODE commands reply arguments in the
3067 protocol specification. The Channel ID is now sent in both
3068 of the commands to identify the channel. Implemented this
3069 new feature to the client and server. Affected files
3070 lib/silcclient/command_reply.c and silcd/command.c.
3072 * Made better checks for invite and ban lists in the JOIN
3073 command in server. Affected file silcd/command.c.
3075 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * The server now performs the incoming host IP/DNS lookup
3078 using the silc_socket_host_lookup and thus does not block
3079 the server anymore. Affected file silcd/server.c.
3081 * Completed the multi-thread support for SILC Scheduler in
3082 the lib/silcutil/silcschedule.c.
3084 * Fixed the configure.in.pre to detect the pthread correctly
3087 * Fixed a deadlock in silc_task_queue_wakeup in the file
3088 lib/silcutil/silctask.c.
3090 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Added new function silc_schedule_wakeup that is used in
3093 multi-threaded environment to wakeup the main thread's
3094 schduler. It needs to be used when a thread adds a new task
3095 or removes a task from task queues. After waking up, the
3096 scheduler will detect the task queue changes. If threads
3097 support is not compiled in this function has no effect.
3098 Implemented the wakeup mechanism to both Unix and WIN32
3099 systems. Affected files are lib/silcutil/silcschedule.[ch],
3100 lib/silcutil/unix/silcunixschedule.c and the
3101 lib/silcutil/win32/silcwin32schedule.c.
3103 * Added new function silc_task_queue_wakeup to wakeup the
3104 scheduler by the specified task queue. Affected file
3105 lib/silcutil/silctask.[ch].
3107 * The silc_socket_host_lookup_start now wakes up the scheduler
3108 after adding the timeout task. Affected file is
3109 lib/silcutil/silcsockconn.c.
3111 * The silc_socket_host_lookup is synchronous now if the threads
3112 support is not compiled in. However, the callback is still
3113 called asyncronously through the scheduler, anyway. Affected
3114 file lib/silcutil/silcsockconn.c.
3116 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Added new function silc_socket_host_lookup to perform
3119 asynchronous IP and FQDN lookups for the socket connection.
3120 Affected files lib/silcutil/silcsockconn.[ch].
3122 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3125 that may or may not compile the mutex support in.
3127 Changed the silc_mutex_alloc interface. It allocates the
3128 mutex now to the sent pointer and returns TRUE or FALSE.
3130 Affected file lib/silcutil/silcmutex.h.
3132 * Wrote the SILC Task Queue interface to support multi-threads.
3133 Affected file lib/silcutil/silctask.[ch].
3135 * Wrote the SILC Scheduler to support multi-threads. Affected
3136 file lib/silcutil/silcschedule.c.
3138 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3141 in lib/silcutil/win32/.
3143 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Defined SILC Mutex API and SILC Thread API and implemented
3146 them for Unix. Affected files are
3147 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3148 lib/silcutil/unix/silcunixmutex.c and
3149 lib/silcutil/unix/silcunixthread.c.
3151 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Fixed the silc_server_remove_clients_by_server's channel
3154 key re-generation. The hash table handling was incorrect
3155 and would not work with many channels. Affected file is
3158 * Fixed some memory leaks around the server code.
3160 * Rewrote the silc_server_get_users_on_channel to support IPv6
3161 based Client ID's. Affected file silcd/server.c.
3163 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3164 specification. However, a separate document must be written
3165 to define the detailed signing procedure and the payload
3166 associated with the flag. Defined the flag to the
3167 lib/silccore/silcchannel.h as well.
3169 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Changed the dynamic tables to static size tables in the
3172 lib/silccrypt/silchmac.c.
3174 * Removed GCC dependencies from the code. A patch by cras.
3176 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * Do not show the error "Error receiving packet bla bla"
3179 in server if it really was not an error (-2 means that reading
3180 is pending). Affected file silcd/server.c.
3182 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Fixed a possible crash in silc_server_remove_clients_by_server
3185 in silcd/server.c. Fixed there also some memory leaks.
3187 * Fixed the silc_idlist_replace_client_id. It could replace
3188 wrong key in the hash table. Affected file silcd/idlist.c.
3190 * Do not check whether there are global users on the channel
3191 if the channel->global_users is FALSE. Affected functions
3192 silc_server_remove_from_one_channel and
3193 silc_server_remove_from_channels in silcd/server.c. Also,
3194 do not check if the removed client is local as we can be
3195 sure that global client was not removed from the channel
3196 and checking for global users is not needed.
3198 * The silc_server_remove_clients_by_server now re-generates
3199 the channel keys correctly for those channels that had
3200 clients removed from them. Affected file silcd/server.c.
3202 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Found the reason of random crashes in the server. We weren't
3205 ignoring the SIGPIPE signal (which can be sent in write())
3206 and it crashed the server. Affected file silcd/silcd.c.
3208 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3210 * Assure that sock->user_data is not NULL in the function
3211 silc_server_packet_send in silcd/packet_send.c.
3213 * Disconnect the remote connection if it could not be added
3214 to any ID lists in the server. The affected file is
3217 * Check in silc_server_packet_send[_real/dest] that the
3218 socket is not disconnecting and ignore the data if it is.
3219 Affected file silcd/packet_send.c.
3221 * Define inline to __inline on native WIN32 compilation.
3222 Affected file includes/silcwin32.h.
3224 * Added some explicit type casts for inline code since MSVC
3225 require them. Affected files lib/silcutil/silcbuffer.h,
3226 lib/trq/silcdlist.h and lib/trq/silclist.h.
3228 * Print warning in log files from now on if the packet
3229 decryption fails. Affected file silcd/server.c.
3231 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Changed the `say' client operation's interface to accept
3234 new `type' argument to indicate the type of the message sent
3235 by the library. The application may filter the library's
3236 messages according the type. The affected file is the
3237 lib/silcclient/silcapi.h.
3239 * Added two new functions to lib/silcclient/silcapi.h:
3240 silc_client_del_client and silc_client_del_client_by_id.
3241 Affected file lib/silcclient/idlist.c.
3243 * Moved the clientincludes.h from includes/ to silc/ and
3244 serverincludes.h from includes/ to silcd/.
3246 * The modes for the CMODE and CUMODE are now passed as
3247 uint32 for application with COMMAND_REPLY. The affected
3248 file is lib/silcclient/command_reply.c.
3250 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3252 * /WHOIS without arguments shows client's own information.
3253 Affected file lib/silcclient/command.c.
3255 * Changed PING to not accept any arguments. The specs
3256 says that client can ping only the connected server so
3257 requiring an argument is not needed. Affected file is
3258 lib/silcclient/command.c.
3260 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Fixed a fatal bug in private message sending and reception
3263 encryption and decryption when using private message keys.
3264 The implementation was incorrect and did not follow the
3265 specification. It causd that some of the message were
3266 lost since it did not use the sending and receiving keys
3267 as the protocol suggests. This has been fixed and will cause
3268 incompatibilities with older clients when sending private
3269 message encrypted with private message keys. Affected files
3270 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3271 and various other in Irssi SILC Client.
3273 Added `responder' boolean argument to the functions
3274 silc_client_add_private_message_key[_ske] to indicate when
3275 the key is added as responder or initiator of the key
3278 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3280 * Removed the silc_ske_check_version function and created
3281 a SilcSKECheckVersion callback. Added also a function
3282 silc_ske_set_callbacks that is now used to set all SKE
3283 callbacks. The callback functions are not given to
3284 the SKE functions anymore, but this function is used to
3287 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3289 * Added `silc_version' argument to the silc_client_alloc
3290 to define the version of the application for the library.
3291 The library will use the version string to compare it
3292 against the remote host's (usually a server) version
3293 string. Affected file lib/silcclient/silcapi.h
3295 * Added the KE protocol context to Key Agreement context
3296 in client library so that we can abort the SKE if it
3297 is in process when we get timeout. Affected file is
3298 lib/silcclient/client_keyagr.c.
3300 * Do not resolve the client ID forever if it returns in the
3301 first time that such client does not exist. This was done
3302 for example with private message. Affected file is
3303 lib/silcclient/client_prvmsg.c.
3305 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Do not add regex.h for WIN32. The affected file
3308 includes/silcincludes.h.
3310 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3311 not work yet 100%. It generates the DLL's automatically
3312 when compiling with --with-win32 under cygwin.
3314 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * lib/contrib/regex.c is not compiled on WIN32.
3318 * Added silc_net_get_socket_opt function to the
3319 lib/silcutil/silcnet.h.
3321 * Added includes/silcwin32.h for WIN32 specific includes
3324 * Do not use ptime structure or any of the posix process
3325 functions on WIN32 in lib/silccrypt/silrng.c.
3327 * Added silc_gettimeofday to provide generic function
3328 for struct timeval on all platforms. Added the function
3329 to lib/silcutil/silcutil.h.
3331 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3334 library as they clearly belong there. As a plus side we
3335 can make the actual socket connection routines platform
3338 Added also new generic function silc_socket_read and
3339 silc_socket_write (that used to be silc_packet_[read/write].
3340 The implementation of these are platform specific.
3342 * Added WIN32 specific routines of silc_socket_[read/write]
3343 to lib/silcutil/win32/silcwin32sockconn.c.
3345 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Added preliminary support for native WIN32 compilation under
3348 cygwin (using the -mno-cygwin option for GCC) to the
3349 ./configure.in.pre. The --with-win32 now prepares the
3350 compilation for native WIN32.
3352 * Rewrote the SILC Scheduler interface in the file
3353 lib/silcutil/silcschedule.h. The scheduler is now context
3354 based and does not have anymore any global static scheduler.
3355 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3356 and created lib/silcutil/win32 directory for WIN32 based
3359 * Added Unix specific network routines to the
3360 lib/silcutil/unix/silcunixnet.c and the old
3361 lib/silcutil/silcnet.c includes now only generic routines.
3363 Added WIN32 specific network routines to the
3364 lib/silcutil/win32/silcwin32net.c.
3366 * Added Unix specific utility functions from the
3367 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3369 * Added WIN32 SILC Scheduler to the file
3370 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3373 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Do not handle JOIN notify in the server if the target client
3376 is not registered (idata->registered == FALSE). The affected
3377 file is silcd/packet_receive.c.
3379 * Update the nickrec->founder in event_cumode in the Irssi SILC
3380 client. Affected file irssi/src/silc/core/silc-channels.c.
3382 * Fixed the CUMODE_CHANGE notify handling in the server when
3383 server and router are announcing their clients on channels.
3384 Now the mode changes are saved and notified correctly. The
3385 affected file is /silcd/packet_receive.c.
3387 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3388 They really did not replace the cache entry in the ID Cache.
3389 Now they do that. Affected file silcd/idlist.c.
3391 * Fixed the KICK notify handling in the Irssi SILC client to
3392 update the channel records so that the kicked client does not
3393 appear to be on the channel. The affected file is
3394 irssi/src/silc/core/silc-channels.c.
3396 * Always update the conn->current_channel when executing command
3397 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3399 * Fixed the KILL notify handling in Irssi SILC client to remove
3400 the killed client on all channels.
3402 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Fixed the silc_parse_command_line to remove extra spaces
3405 from the start and end of the arguments. Affected file is
3406 lib/silcutil/silcutil.c.
3408 * Cancel and free any active protocol in the function
3409 silc_server_close_connection. Affected file silcd/server.c.
3411 * Cancel and free any active protocol in the function
3412 silc_client_close_connction. Affected file is
3413 lib/silcclient/client.c.
3415 * Do not execute the KILL command for clients that are in
3416 history (ie. they are not in the network). Affected file is
3419 * Fixed KILL notify handling, client does not crash anymore.
3420 Affected file irssi/src/silc/core/silc-channels.c.
3422 * Reduced the default packet buffer size from 2048 to 1024 in
3423 lib/silccore/silcpacket.c.
3425 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3426 counter to the SKE context that is incresed when the SKE library
3427 performs async operation outside the library. If the outside
3428 process frees the SKE context and FREED status will be set
3429 and the library will detect after the sync operation that the
3430 libary is freed. The affected files are
3431 lib/silcske/silcske[_status].[ch].
3433 * Resolve the client entry information in the function
3434 silc_client_channel_message to assure that NULL pointer is not
3435 passed as client entry to the application. */
3437 * Fixed the task timeout calculation to assure that there is
3438 never negative timeouts. The affected file is
3439 lib/silcutil/silcschedule.c.
3441 * Fixed the channel user mode notification sending in server.
3442 It was sent point-to-point to the router (or to server by router)
3443 but it needs to be destined to a channel. The routines now
3444 supports sending the channel user mode notifys to the channels
3445 when announcing clients and channels. Affected files are
3446 silcd/server.c and silcd/packet_receive.c.
3448 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3449 It did not actually replace the old channel entry in the cache.
3450 Affected file lib/silcclient/client_notify.c.
3452 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Fixed a possible crash in silc_packet_send_prepare. It now
3455 assures always that there is enough space in the buffer and
3456 at the tail area of the buffer (for MAC).
3458 Fixed the inbound buffer reallocation in silc_packet_read.
3459 It was old code and did not handle the reallocation correctly.
3462 The affected file is lib/silccore/silcpacket.c.
3464 * Fixed buffer overflow in silc_parse_nickname in the file
3465 lib/silcutil/silcutil.c.
3467 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3469 * make install generates new server keys only if there is not
3472 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3475 Added check that if the NOREPLY is set then we will not send
3476 the away message. This avoids infinite loop of away messages
3477 if both clients are away. The affected file is
3478 lib/silcclient/client_prvmsg.c.
3480 * Fixed client crash if /NICK was given without arguments.
3481 Affected file lib/silcclient/command.c.
3483 * Server does not send the invite list in INVITE command back
3484 to the client if the list was not altered. Added this notion
3485 to the protocol spec as well. Affected file silcd/command.c.
3487 Fixed possible crash in INVITE command by checking the
3488 value of silc_server_get_client_route command.
3490 * Fixed the INVITE notify type handling. The arguments are now
3491 taken in correct order and client does not crash. The affected
3492 file is irssi/src/silc/core/silc-channels.c.
3494 Removed the "Inviting xxx to channel" message from the
3495 client library away and let the application handle it.
3496 Affected file lib/silcclient/command.c. Added that message
3497 to Irssi SILC client's message formats.
3499 * Fixed CMODE command crash in client. It now checks the
3500 amount of arguments correctly and does not crash. The affected
3501 file is lib/silcclient/command.c.
3503 * Do not create new channel automatically in silc_channels_join
3504 but check whether the channel by that name already exists.
3505 Affected file irssi/silc/core/silc-channels.c.
3507 * Do not send the SERVER_SIGNOFF to router if the disconnected
3508 entity was the router. Affected file silcd/server.c.
3510 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3511 SILC client as it was missing from there.
3513 Added the handling of the KICK notify to the Irssi SILC client
3514 as it was missing. Added "you have been kicked" message to
3515 Irssi SILC client's message modules formats.
3517 Added the handing of the KILL notify to the Irssi SILC client
3518 as it was missing. Added the kill message module formats
3521 The affected file is irssi/src/silc/core/silc-channels.c.
3523 * The router did not save the channel mode the server announced.
3524 Affected file silcd/packet_receive.c.
3526 * Fixed a possible crash in INFO command in server. If the
3527 server did not provide the server info it crashed. Affected
3528 file silcd/command.c.
3530 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Fixed the GETKEY command in the server to check also the
3533 global list. Otherwise the GETKEY would not work correctly
3534 in normal SILC server. Affected file silcd/command.c.
3536 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Fixed GETKEY crash, it crashed if the command did not succseed.
3540 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3543 is now real and not just an macro interface to GMP.
3545 Removed the entire GMP from the source tree and imported new
3546 NSS MPI library instead. Reason for removing GMP is that it is
3547 extremely large and compiles extremely slow. The NSS MPI
3548 is only a few files and compiles in less than 10 seconds.
3549 The speed is also about the same as GMP. The MPI is imported
3550 to lib/silcmath/mpi.
3552 If the system has GMP installed we will still use the GMP.
3553 If it is not then the NSS MPI will be compiled.
3555 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Merged a long nickname (127 characters long) crash bugfix from
3558 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3560 * Merged a freed memory reference bugfix from Irssi CVS tree.
3561 Affected file irssi/src/core/commands.c.
3563 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3565 * Added the server's public key sving and verification to the
3566 server when performing the SKE. This was missing and the
3567 remote server's (or router's) public key was accepted without
3568 checking whether we have it previously or trust it at all.
3569 Affected file silcd/protocol.c.
3571 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Check in the silc_server_timeout_remote if protocol is active
3574 and make sure that the protocol's final callback is called so
3575 that all memory if freed. Affected file silcd/server.c.
3577 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * silc_server_whois_send_reply crashed the server if the nickname
3580 was 127 characters long. Affected file silcd/command.c.
3582 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Added sanity check to the silc_server_new_client. If the hostname
3585 is provided inside username then check that the provided hostname
3586 really is the same as the resolved one. If the hostname was not
3587 resolved then check it from the public key. Affected file is
3588 silcd/packet_receive.c.
3590 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3591 if the server disconnected us and the connection is not valid
3592 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3594 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3595 the library to the lib/silcutil/silcutil.[ch].
3597 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Close log file after open. Affected file
3600 lib/silcutil/silclog.c.
3602 * Check whether sock == NULL in silc_client_send_packet and return
3603 if it is. Affected file lib/silcclient/silcclient.c.
3605 * Check rec->entry == NULL in the Irssi SILC Client before
3606 sending the channel message. Affecte file is
3607 irssi/src/silc/core/silc-servers.c.
3609 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Merged a splitted window bugfix from Irssi CVS tree. The
3612 affected file is irssi/src/fe-text/textbuffer-view.c.
3614 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3615 It did not print nickname.
3617 * Improved the distributions system a bit.
3619 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3622 irssi/src/fe-text/gui-window.c.
3624 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3625 to in-active server. The affected file is
3626 irssi/src/silc/core/client_ops.c.
3628 * Resolve the client in USERS command reply if the entry does
3629 not have username resolved. The affected file is
3630 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3631 command to WHOIS command to really resolve stuff. The USERS
3632 is not used any more in any critical section so WHOIS can
3633 be used even though it might be slower than IDENTIFY.
3635 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3638 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Changed the protocol API a bit more consistent in the
3641 lib/silccore/silcprotocol.[ch].
3643 * Changed the following headers to ROBODoc format:
3645 lib/silccore/silcpayload.h
3646 lib/silccore/silcprotocol.h
3647 lib/silccore/silcsockconn.h
3649 All core library headers are now formatted.
3651 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3653 * Fixed a bug in Irssi SILC client; do not show that you are
3654 server/router operator if you really are not. Affected file is
3655 irssi/src/silc/core/client_ops.c.
3657 * Renamed silc_command_free_payload to silc_command_payload_free.
3658 Affected file lib/silccore/silccommand.h
3660 * Added silcmath.h to include the prototoypes of various routines
3661 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3664 * Changed the following headers to ROBODoc format:
3666 lib/silccore/silcchannel.h
3667 lib/silccore/silccommand.h
3668 lib/silccore/silcid.h
3669 lib/silccore/silcidcache.h
3670 lib/silccore/silcmode.h
3671 lib/silccore/silcnotify.h
3672 lib/silccore/silcpacket.h
3673 lib/silcmath/silcmath.h
3675 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Added checking to the server code not to start the server if
3678 ciphers and stuff are not configured properly. Affected files
3679 silcd/serverconfig.[h] and silcd/server.c.
3681 * Changed the layout of the header files of the public interfaces
3682 in the SILC libraries. The new layout supports ROBODoc
3683 documentation tool (and some others) so that it is easy to create
3684 a library reference manual. All the other headers and source
3685 code must still follow the CodingStyle document. Also source
3686 code must not include these ROBODoc stuffs, only the headers.
3687 Furthermore, all public interface headers must now be named
3688 by using `silc' prefix, example: silcapi.h, silccipher.h.
3689 Some files were renamed due to this. All the other headers
3690 must not be used as public interfaces. I will update the
3691 CodingStyle document later. Changed following headers, so far:
3693 lib/silcclient/silcapi.h
3694 lib/silccore/silcauth.h
3695 lib/silccore/silcprivate.h
3696 lib/silccrypt/silcdh.h
3698 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Removed silc_client_packet_send_flush from the client library
3703 as it is not needed. Affected file lib/silcclient/client.[ch].
3705 * Added printing of message of unresolved authentication method
3706 to the Irssi SILC client. Added it to the module formats.
3707 Removed the same message from the client library.
3709 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Added new distribution feature, DISTLABEL. Every distribution
3712 can define own preprocessor label that can be used in the
3713 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3714 file distributions, acconfig.h.pre and prepare.
3716 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Added Makefile.defines_int to include the actual definitions
3719 for Makefile.defines.in. Tested the new distribution system,
3720 created distributions and tested installation.
3722 * Added AWAY message printing to the Irssi SILC client. Added
3723 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3725 * Added SCONNECT command to call the SILC's CONNECT command.
3726 Cannot use CONNECT directly since Irssi uses that internally.
3727 Affected file irssi/src/silc/core/silc-servers.c.
3729 Added ACTION local command. It is same as ME command but takes
3730 the channel as mandatory argument.
3732 Rewrote some of the Irssi's help files to suite for SILC
3735 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Added Makefile.defines[.in] that should for now on be included
3738 in all Makefile.am file in the source tree. That file includes
3739 all common compilation definitions for SILC source tree.
3741 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Minor changes to the ./prepare script to change the package
3744 name according the distribution name to the configure.in.
3746 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Created new distribution system. Added file `distributions'
3749 that defines all the distributions that can be created out of
3750 the SILC source tree. The ./prepare script now reads that
3751 file to determine how to prepare the distributions. The
3752 first argument to the ./prepare is the name of the distribution
3753 and second is the version of the distribution. If given
3754 without arguments it creates the default (toolkit) distribution
3755 with the default version (defined in ./prepare).
3757 All Makefile.am files that are subject to the distributions
3758 are now named as Makefile.am.pre. These are ./Makefile.am
3759 and lib/Makefile.am. Others may be changed later.
3761 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Added invite list, ban list, some key management and connection
3764 error message printing to module formats in the Irssi SILC client.
3766 * Added new silc_client_set_away_message to set the away message
3767 that is back to the person who sent private message. The
3768 affected file lib/silcclient/silcapi.h and the
3769 lib/silcclient/client_prvmsg.c.
3771 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3773 * Fixed the private message sending in the Irssi SILC client,
3774 added local command KEY to the Irssi SILC client.
3776 Added key management and key agreement message formats to the
3777 irssi/src/fe-common/silc/module-formats.[ch].
3779 Added USERS (alias WHO) printing, server/router operator
3780 indication and LIST command printing to the module formats.
3782 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Fixed channel joining notify handling, cumode notify handling
3785 from Irssi SILC client.
3787 * Added SILC specific module-formats to the Irssi SILC client so
3788 that SILC specific message hilighting, colors etc is possible.
3789 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3791 Added channel mode, channel user mode, actions, notices,
3792 whois and whowas printing to the the module-formats.c.
3794 * Fixed a bug in channel deletion in the server. The channel
3795 is not left to the cache even if the channel founder auth mode
3796 is set when there are no users anymore on the channel. Affected
3797 file silcd/server.c.
3799 * The silc_net_localhost now resolves the entire hostname including
3800 the domain name. Affected file lib/silcutil/silcnet.c.
3802 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Changed the ask_passphrase client operation to be ascynchronous.
3805 It has now a completion callback and a context that the
3806 application must call after it has got the passphrase from
3807 the user. Affected files lib/silcclient/silcapi.h,
3808 lib/silcclient/protocol.c, lib/silcclient/command.c and
3811 Added SilcAskPassphrase callback that the application calls
3812 to deliver the passphrase to the library.
3814 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3815 The public key verification and especially a certificate
3816 verification is asynchronous procedure.
3818 Added new SILC_SKE_STATUS_PENDING status to indicate the
3819 request is pending and a callback will be called to finalize
3822 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3823 indicate that remote end did not send its public key (or
3824 certificate), even though we require it. Added check for this
3825 condition in the SKE. This was a security bug, now fixed.
3827 Defined new SilcSKEVerifyCbCompletion callback that is called
3828 when the verification process is completed.
3830 The affected files lib/silcske/silcske_status.h and
3831 lib/silcske/silcske.[ch].
3833 * Changed the verify_public_key client operation to be async
3834 as well. Defined SilcVerifyPublicKey callback that is used to
3835 indicate the success of the public key verification process.
3837 Changed the server and client to use the new async client
3840 * Changed the Irssi SILC client's internal scheduler to be called
3841 twice as many times as it used to be. As a result the client
3842 should be a bit faster now. Affected file is
3843 irssi/src/silc/core/silc-core.c.
3845 * Added support to Irssi SILC client of asynchronous public key
3846 verification and passphrase inquiry. Affected file is
3847 irssi/src/silc/core/silc-core.c.
3849 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Do not say "You have left channel %s" in client library.
3852 Moved it to the application. Affected files are
3853 lib/silcclient/command.c and silc/client_ops.c.
3855 * Fixed silc_client_get_clients. Command context was not
3856 duplicated and was freed memory in the callback. Affected
3857 file lib/silcclient/idlist.c.
3859 * Do not say "you are now talking..." on JOIN command in the
3860 client library. The appliation must handle it.
3862 * Do not say ".. changed topic to" in command reply in the
3863 client libary. The application must handle it.
3865 * Fixed TOPIC command sending in the client library.
3867 * Fixed a memory leak in silc_client_command_free in the file
3868 lib/silcclient/command.c.
3870 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3872 * Imported a modified version of Irssi client to the source tree.
3873 The Irssi will be used to create a new client called
3874 Irssi SILC. Imported to irssi/.
3876 Added silc_core_init_finish function to the Irssi. Affected
3877 file irssi/configure.in.
3879 A lot changes in the Makefile.ams around the irssi tree.
3881 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Do not rehash if the new size is same as the old size of the
3884 hash table, in the silc_hash_table_rehash*. The affected file
3885 lib/silcutil/silchashtable.c.
3887 * Replaced hash_table_del_by_context calls from the server
3888 (when channel->user_list and client->channels) to the
3889 hash_table_del as it is sufficient and faster.
3891 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Added silc_hash_table_list, silc_hash_table_get and the
3894 SilcHashTableList structure to provide an alternative way to
3895 traverse the hash table. The affected files are
3896 lib/silcutil/silchashtable.[ch].
3898 * Changed the server's idlist routines to use the hash table
3899 routines to optimize the code.
3901 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Replaced the client entry's `channel' list and channel entry's
3904 `user_list' list to hash tables for optimized lookup. Changed
3905 the code to use the hash table interface around the code.
3906 Affected file lib/silcd/idlist.[ch].
3908 * Added `auto_rehash' boolean argument to the function
3909 silc_hash_table_alloc to indicate whether the hash table should
3910 auto-rehash when it thinks is appropriate time. It will
3911 increase the hash table size if the there is twice as much
3912 entries in the table than the size of the table, and will
3913 decrease the size if there are twice as less entries than
3914 the size of the table.
3916 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3920 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * silc_idcache_purge_by_context deletes the entry now by context
3923 as it is supposed to do. Affected file lib/silccore/idcache.c.
3925 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3926 client is not anymore valid (WHOWAS givens the info) and not
3927 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3929 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Removed the `data' and `data_len' arguments from the ID Cache
3932 interfaces and added `name' argument. ID Cache does not handle
3933 anymore the binary data only a names associated with given ID.
3935 * When hashing a Client ID with silc_hash_id the entire ID is
3936 not hashed anymore, instead only the hash of the Client ID is
3937 hashed. This way we can access the Client ID from the cache
3938 with Client ID but with the hash of the ID (which is a hash of
3939 the nickname) as well without any difference in performance.
3941 Added also silc_idcache_find_by_id_one_ext to do one on one
3942 searching when we have the actual ID. Added also function
3943 silc_hash_client_id_compare. The affected files are
3944 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3946 * When hashing the name associated with a ID it is always done
3947 in lowercase. This way we can access the cache without worrying
3948 about case-sensitivity, even though, for example nicknames are
3951 * Fixed a bug in server with channel message sending. It put
3952 wrong ID type as destination ID. The affected file
3953 silcd/packet_send.c.
3955 * silc_idcache_del_by_context now deletes from all hash tables
3956 by context. Affected file lib/silccore/idcache.c.
3958 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Changed the client library to use the new ID Cache interface.
3961 Changes around the source tree.
3963 * Added silc_hash_table_rehash_ext to rehash with specific
3964 hash function. Affected file lib/silcutil/silchashtable.[ch].
3966 * Added silc_hash_string_compare to compare two strings in the
3967 hash table. Affected file lib/silcutil/silcutil.[ch].
3969 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added new function silc_idcache_del_by_context into the
3972 lib/silccore/idcache.[ch].
3974 * Changed the server's ID list routines to use the new ID Cache
3975 interface. Changes around the source tree.
3977 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added silc_hash_table_del[_by_context]_ext functions in to the
3980 lib/silcutil/silchashtable.[ch].
3982 Removed silc_hash_table_find_all* routines and added new
3983 silc_hash_table_find_foreach to replace them.
3985 Added silc_hash_table_replace_ext function as extended
3986 replacing function. Separated the simple hash table interface
3987 from the extended hash table interface in the file
3988 lib/silcutil/silchashtable.h.
3990 * Fixed minor bugs and changed it to use some of the new
3991 hash table functions in lib/silccore/idcache.c
3993 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * Added new function silc_hash_table_find_all to return all keys
3996 in the hash table by the specified key. As the hash table is
3997 collision resistant it also makes it possible to have several
3998 duplicate keys in the hash table. This function may be used to
3999 find all of the keys from the hash.
4001 Added user_context arguments to the SilcHashFunction,
4002 SilcHashCompare and SilcHashDestructor to deliver user specified
4005 Added new fuctions silc_hash_table_find[_all]_ext to do
4006 extended lookup with specified hash and compare functions and
4007 specified user contexts.
4009 Added new function silc_hash_table_add_ext to add the key
4010 with specified hash function and user context.
4012 Added new function silc_hash_table_foreach to traverse all
4013 entrys in the hash table. Added SilcHashForeach callback
4016 Added new function silc_hash_table_del_by_context to delete
4017 the entry only if the context associated with the key matches.
4019 Affected files are lib/silcutil/silchashtable.[ch].
4021 * Removed silc_hash_[server/client/channel]_id and added just
4022 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4023 silc_hash_id_compare to compare two ID's using as the hash table
4024 comparison function. Added also silc_hash_data to hash
4025 binary data and silc_hash_data_compare to compare it.
4027 * Removed silc_idlist_find_client_by_hash as it is not needed
4028 anymore. Affected file silcd/idlist.[ch].
4030 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4031 to use internally the SilcHashTable. The new ID Cache is a lot
4032 faster than the old one. Some of the ID Cache interface was also
4033 rewritten and obsolete and stupid functions were removed.
4035 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Added entry_count field to the SilcHashTable to keep the number
4038 of the entries in the table. Implemented the function
4039 silc_hash_table_rehash. Added new function
4040 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4042 Fixed a minor bug in silc_hash_table_free.
4044 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4045 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4046 into the lib/silcutil/silcutil.[ch].
4048 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Implemented a collision resistant hash table into the
4051 lib/silcutil/silchashtable[ch]. See the header and the source
4052 for the SilcHashTable API.
4054 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Merged dotconf version 1.0.2 into lib/dotconf.
4058 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Do not compile anything in lib/silcsim/* if the SIM support
4061 is not enabled. The tree should now compile without problems
4064 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Compiled the SILC under cygwin. Compiled and tested briefly
4067 without problems. More tests needed. The SIMs didn't compile
4070 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4072 * Fixed possible crash in silc_get_username in the
4073 lib/silcutil/silcutil.c.
4075 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Fixed a va_arg in silc/client_ops.c.
4079 * Oops, RC5 routines were named AES and caused some problems
4080 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4082 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Added new SilcIDIP structure into the lib/silccore/id.h and
4085 replaced the old `ip' fields from all SILC ID's to that type.
4086 This is a step towards IPv6 support.
4088 The silc_id_get_len takes now the ID as an extra argument.
4089 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4090 both IPv4 and IPv6 based ID's.
4092 The affected files are lib/silccore/id.[ch] and other files
4093 around the tree using these routines.
4095 * Removed the ID length arguments in server from various
4096 silc_server_send_notify_* routines -> they are not needed
4099 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Fixed memory leak in silc_encode_pem_file in the file
4102 lib/silcutil/silcutil.c.
4104 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4106 * Check minor version as well in the SKE. Affected files are
4107 silcd/protocol.c and lib/silcclient/protocol.c.
4109 * Added --identifier option to the server so that an identifier
4110 can be when creating the public key for the server. Affected
4111 file is silcd/silcd.c.
4113 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4114 lib/silccrypt/silcpkcs.c.
4116 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Register default ciphers and stuff when using -C option with
4119 the server. Affected file sildc/silcd.c.
4121 * Put back the servers public key filename format, it is better
4122 than the new one. For now, the client keys are saved with the
4123 new filename format. The affected file silc/client_ops.c.
4125 * Implemented the Cipher API for the rest of the ciphers that
4126 did not implement it or implemented it the wrong way.
4128 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Register default ciphers and stuff when using the -S option
4131 in the client. Affected file silc/silc.c. Same also when
4132 creating new key pair with -C option.
4134 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4136 * Fixed the silc_verify_public_key client operation function to
4137 save the public keys differently. The fingerprint is now
4138 used as filename and not the hostname. This way also the
4139 client keys are saved uniquely and not with hostnames. The
4140 affected file is silc/client_ops.c.
4142 * Trimmed the silc_hash_fingerprint function to remove extra
4143 whitespaces from the end of the fingerprint. The affected
4144 file is lib/silccrypt/silchash.c.
4148 * Added silc_cipher_register_default function to register all
4149 default ciphers. It can be used when configuration files
4150 does not exist and the application does not want any specific
4151 ciphers in any specific order.
4153 The SilcDList is now used as silc_cipher_list dynamically
4154 allocated cipher list. Removed the static list all together
4155 and now all ciphers must be allocated to the dynamic list.
4156 The silc_cipher_alloc routine was changed to check only the
4159 All silc_cipher_* routines that used to return int returns
4162 The affected files lib/silccrypt/silccrypt.[ch].
4164 * The same thing was done to silc_hash_* as for silc_cipher_*
4165 routines. Affected files lib/silccrypt/silchash.[ch].
4167 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4168 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4169 Added also silc_pkcs_[un]register[_default] functions.
4170 Removed the data_context from the PKCS API.
4172 * Added silc_hmac_register_default function to register default
4173 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4174 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4175 to unregister all hmacs at once.
4177 * Register the default ciphers, hash functions, PKCSs and HMACs
4178 if client's configuration file does not exist. The affected
4181 * The client did not load the hash functions from the SIM
4182 modules at all. Added support for this. Affected file is
4183 silc/clientconfig.c.
4185 * When decoding public key with silc_pkcs_public_key_decode, check
4186 the supported algorithm only if PKCS are registered. Affected
4187 file lib/silccrypt/silcpkcs.c. The same was done with the
4188 silc_pkcs_private_key_decode.
4190 * Fixed the SILC List routines to keep the list always in order.
4191 It used to change the list's order when traversing the list but
4192 not it preserves the order. Affected file lib/trq/silclist.h.
4194 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Added the client library to use the SilcSocketConnection's
4197 reference counter (by silc_socket_dup) to prevent the bug that
4198 the socket object may be freed underneath async operation.
4200 * The name resolv library checking fixes in the configure.in.pre.
4203 * Created new version of the protocol drafts for future
4204 development. The -03 drafts are the ones that will be changed
4205 in the trunk now and the -02 will remain as they are.
4207 * Send list of CUMODE notifys to the router when announcing
4208 the channel users to the router. Affected file silcd/server.c.
4209 If the router receiving channel founder CUMODE for a channel
4210 that already has channel founder it will send CUMODE notify
4211 to the sender to remove the channel founder rights from the
4212 announced client. Affected file silcd/packet_receive.c.
4214 * The CUMODE notify may now use Server ID as well as the entity
4215 who changes the mode. Updated protocool specs.
4217 * Updated INSTALL and README files.
4219 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * New web pages in the http://silc.pspt.fi. The pages was
4226 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Implemented the [DenyConnectin] config section in the server.
4229 Added silc_server_config_denied_conn to check whether incoming
4230 connection is denied. Affected file silcd/serverconfig.[ch].
4232 * Do not check the ports when checking the incoming configuration
4233 data if the port is 0, meaning any. Affected file is
4234 silcd/serverconfig.c.
4236 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Fixed buffer overflow in silc_string_compare in the file
4239 lib/silcutil/silcutil.c.
4241 * Fixed double free in silc_server_command_leave in the file
4244 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Fixed the version checking in the server. Affected file is
4249 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Fixed the configuration data fetching when accepting new
4252 connections in the server. Affected file silcd/server.c.
4254 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Added `sender_entry' argument to the function
4257 silc_server_packet_relay_to_channel so that we can check
4258 whether some destination actually belongs to the same route
4259 the sender belongs (ie, we must not resend the packet to the
4260 sender). Affected file silcd/packet_send.[ch].
4262 * Added `servername' field to the SilcClientEntry in the server
4263 to hold the name of the server where client is from. Affected
4264 file is silcd/idlist.h.
4266 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Moved the channel message encrypting in the router betwen
4269 router connections from silc_server_channel_message to the
4270 silc_server_packet_relay_to_channel since we want to check
4271 whether we have anybody channel before encrypting anything.
4272 Affected files silcd/packet_[receive/send].c.
4274 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Fixed the [AdminConnection] server config section to support
4277 multiple entries. Affected file silcd/serverconfig.c.
4279 * Added support into the server to check the validity of the
4280 incoming connection before executing any KE or authentication
4283 * The connection configuration is now saved to the KE and
4284 connection auth protocol contexts and not fetched anymore in
4285 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4287 * The local hosts listenning address and port is also resolved
4288 now when starting the server. We want to have the socket object
4289 to include the real address and port for the listener. Added
4290 new function silc_net_check_local_by_sock into the files
4291 lib/silcutil/silcnet.[ch].
4293 * Fixed a broadcast bug in server -> do not broadcast if we
4296 * Fixed a routing bug. Do not route broadcast packets ever.
4297 Broadcast packets must be processed always and not routed since
4298 they may be destined to some other host than yourself and thus
4299 would get routed without no good reason. Affected file is
4302 * Added function silc_server_config_is_primary_route to check
4303 whether primary router connection has been configured (a router
4304 configuration that we are initiating). If there is not, we
4305 will assume that there is only two routers in the SILC network
4306 and we will use the incoming router connection as our primary
4307 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4309 * Changed the order of the broadcasting. Broadcast _after_ the
4310 packet has been processed not before. Affected file is
4313 * Fixed a [ClientConnection] parsing bug. The port was never
4314 parsed correctly thus resulting to port 0. Affected file
4315 silcd/serverconfig.c.
4317 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4318 argument and did not set the broadcast packet flag. Affected
4319 file silcd/packet_send.c. Fixed same bug in the function
4320 silc_server_send_notify as well.
4322 * If we receive NEW_ID packet for our own ID in the server, ignore
4325 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Removed the nickname from the Private Message Payload.
4330 Updated the code and the protocol specs.
4332 * Updated protocol specs for submitting to the IETF.
4334 * Tweaked the Random Number Generator a bit. Affected file
4335 lib/silccrypt/silcrng.c. Exported a new function
4336 silc_rng_[global]_add_noise which can be used to add more
4339 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Do not parse packets with different timeout when protocol
4342 is active -> may cause problem with rekey. Affected file
4345 * When server receives signoff notify it must not create
4346 new channel key if the client is on any channels since the
4347 sender of the signoff notify will create it.
4349 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Added printing of error messages during SKE protocol from the
4352 failure packet sent by server during SKE. Affected file
4355 * Removed the client's failure_callback handling with timeout
4356 and handle it immediately when received.
4358 * The SKE library returned wrong type in SUCCESS and FAILURE
4359 packets. They must be 32 bit MSB not 16 bit MSB.
4361 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Ok, rewrote the logic of the re-key and now it seems to work.
4364 I tested it on high traffic with frequent re-keys without
4365 problems. Added hmac_receive (and renamed hmac to hmac_send)
4366 in SilcClientConnection in lib/silcclient/client.h and
4367 in SilcIDListData in silcd/idlist.h. Also, removed the
4368 SilcPacketParserContext's cipher and hmac fields as they are
4369 not needed anymore and actually caused some problems when
4370 the ciphers and hmac's changed underneath the packet parser.
4372 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * If re-key protocol is active then process the incoming packets
4375 synchronously since we must assure that icoming packets encrypted
4376 with the old key is processed before the new keys is set to
4377 use. This is true other packets than for REKEY packets.
4378 Affected file silcd/server.c. The same was done to client library
4379 as well, affected file lib/silcclient/client.c.
4381 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Fixed bug in client and server to accept the force send if
4384 the packet is send from silc_[server/client]_packet_process
4385 function. Otherwise the packets are never delivered, oops.
4387 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Disable force sending of packets when REKEY protocol is active.
4390 We must assure that no packet is sent directly when rekey is
4391 performed. All packets must be sent through packet queue.
4392 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4393 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4394 function is silc_[server/client]_packet_send_real to check
4397 * Replaced the SIM paths from example config files to
4398 /usr/local/modules. Also, make install creates now
4399 /usr/local/silc/logs directory to hold all the SILC server
4402 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Made the configure.in.pre work on Solaris. Patch by salo.
4406 * Made all ciphers compatible with non-x86 machines. Defined
4407 CBC mode macros into lib/silccrypt/ciphers_def.h.
4409 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Fixed the make install.
4413 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * When MAC computation fails the silc_packet_decrypt returned 0
4416 even though it was supposed to return -1. Fixed this. The
4417 affected file is lib/silccore/silcpacket.c.
4419 * Do not replace the config files in /etc/silc (in make install)
4420 if they already exist. Affected file ./Makefile.am.
4422 * Do not send re-key packets immediately but through packet queue.
4423 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4425 * Changed silc_net_check_host_by_sock to return FALSE if the
4426 IP/DNS could not be resolved. Though, it returns the IP address
4427 now even if it could not resolve it (but returns also FALSE).
4428 Affected file lib/silcutil/silcnet.[ch].
4430 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Added silc_pkcs_decode_identifier to decode the public key's
4433 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4434 Added also silc_pkcs_free_identifier. Added also new context
4435 SilcPublicKeyIdentifier.
4437 * Added -S option to the silc client. It is used to dump the
4438 contents of the specified public key file.
4440 * Changed the PKCS api to return the public key length when
4441 setting the public key.
4443 * Fixed a fatal bug in the public and private key file loading.
4444 Affected file lib/silccrypt/silcpkcs.c.
4446 * Execute the packet parsing for client with zero (0) timeout
4447 if the protocol is active. Affected file silcd/server.c.
4449 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Made the key generation options to the silcd program. Added
4452 -C option, equivalent to client's option.
4454 * Added new [ServerKeys] config section to the server. It
4455 configures the server's public and private key.
4457 * Defined generic Public Key Payload into the protocol
4458 specification to send specific type of public keys and
4461 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4462 public key or certificate.
4464 * Implemented the GETKEY command to the server and to the
4465 client library and on user interface.
4467 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Made preliminary `make install' work.
4471 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added SilcServerRekey context into silcd/idlist.h.
4475 * Added the PFS support as defined in the specification to the
4476 SKE protocol. Affected files lib/silcske/*.c.
4478 * Added `ske_group' field to the SilcServerRekey context to hold
4479 the number of the SKE group that is used with PFS in re-key.
4480 Affected file silcd/idlist.h.
4482 * Added PFS re-key support to the server. Affected file is
4485 * Added silc_protocol_cancel to cancel execution of the next
4486 state of the protocol. Affected file is
4487 lib/silccore/silcprotocol.[ch].
4489 * Added the re-key support with and without PFS to the client
4490 library. Re-key is performed once in an hour, by default.
4492 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4493 Added silc_client_rekey_callback and silc_client_rekey_final.
4494 Affected files are lib/silcclient/protocol.[ch] and
4495 lib/silcclient/client.[ch].
4497 * Removed the `hmac_key' and `hmac_key_len' fields from the
4498 SilcClientConnection structure; not needed. Affected file is
4499 lib/silcclient/client.h.
4503 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Do not ask whether user wants to use the negotiated private key
4506 for private messages, just use it. Affected file is
4507 silc/local_command.c.
4509 * Added `send_enc_key' and `enc_key_len' fields to the
4510 SilcIDListData structure since they are needed in the re-key
4511 phase. Affected file is silcd/idlist.[ch].
4513 * Implemented the simple re-key protocol into the server.
4514 Affected files silcd/server.c and silcd/protocol.[ch]. The
4515 re-key will be performed once in an hour, by default.
4517 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4518 Added silc_server_rekey, silc_server_rekey_callback and
4519 silc_server_rekey_final.
4521 * Removed Tunneled flag from the protocol. Updated the code
4522 and the specifications.
4524 * Adde `pfs' field to the SilcIDListData to indicate whether
4525 the PFS is to be performed in the re-key. Affected file is
4528 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4531 int64 of at least the xintXX size. If void * is less that 4
4532 bytes uint32 * will be used. Defined bool as boolean.
4534 * Changed _ALL_ unsigned long and unsigned int to uint32,
4535 unsgined short to uint16 in the source tree.
4537 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4538 not handle clients that has entry->data.registered == FALSE.
4539 They are not in the network anymore. Affected file is
4542 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Implemented the sending of the SERVER_SIGNOFF notify in the
4545 server. Affected file is silcd/server.c.
4547 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4548 Added also silc_notify_payload_encode_args into the
4549 lib/silccore/silcnotify.[ch].
4551 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4552 Affected file silcd/packet_receive.c.
4554 * Implemented the SERVER_SIGNOFF notify handling in the client
4555 library. Affected file lib/silcclient/client_notify.c. Also,
4556 implemnted the printing of the SERVER_SIGNOFF info to the
4557 application. Affected file silc/client_ops.c.
4559 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4560 if the deleting was successful. Affected file silcd/idlist.[ch].
4562 * Added support for public key authentication in the connection
4563 authentication protocol in the client library. Affected file
4564 lib/silcclient/protocol.c.
4566 * Changed the server's silc_idlist_get_clients_by_* interface
4567 to support already allocated array so that new entries may be
4568 added to pre-allocated array. Affected file silcd/idlist.[ch].
4569 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4570 and command replies.
4572 * All command reply functions in the server now calls the
4573 pending command callback even if error occured. This way the
4574 error will be delivered to the client as well. Affected files
4575 silcd/command.c and silcd/command_reply.c.
4577 * Fixed INFO command to return local server's info if no server
4578 was provided. Affected file lib/silcclient/command.c.
4580 * Removed RESTART command for good. Updated the code and the
4583 * Rewrote parts of the task system. It is a bit simpler now.
4584 Removed unsued task priorities. The affected files are
4585 lib/silcutil/silctask.[ch].
4587 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Moved the USERS printing from the library to the application.
4590 Affected files lib/silcclient/command.c and silc/client_ops.c.
4592 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Added channel key re-key support. The re-key is perfomed
4597 only by the router and is done once in an hour. Added `rekey'
4598 field to the SilcChannelEntry in the server. Affected files
4599 silcd/server.c and silcd/idlist.h.
4601 * Added silc_task_unregister_by_context into the file
4602 lib/silcutil/silctask.[ch].
4604 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Added SILC_UMODE_GONE mode to indicate when the client is not
4607 present in the SILC network. Added also support to the local
4608 command AWAY that will set this mode. Added support of showing
4609 "xxx is gone" in WHOIS command. The USERS command shows the
4610 gone status as well.
4612 * Fixed setting server and router operator privileges in the
4613 server's UMODE command. Affected file silcd/command.c.
4615 * Merged the SKE KE1 and KE2 payloads into one payload. The
4616 new KE payload is equivalent to the old KE2 payload.
4618 Cleaned up the SKE Start Payload parsing. It now uses the
4619 simple buffer unformatting to do the parsing. A lot faster
4622 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4623 to the SKE that is used to indicate whether both of the SKE
4624 parties should perform authentication. By default only the
4625 responder performs authentication. By setting this flag also
4626 the initiator must do authentication. By default it is unset
4627 since in normal SKE case, client to server connection, only
4628 the responder should do authentication. When doing SKE between
4629 two clients both should perform authentication. Updated the
4630 code and the protocol specs.
4632 * A little fix to IDENTIFY command in the server. Search the
4633 client first by hash not nickname. Affected file is
4636 * Fixed the silc_client_close_connection to support closing
4637 the client to client connections wihtout deleting too much
4638 data. Affected file lib/silcclient/client.c.
4640 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4641 are received if protocol used to be active but is not anymore
4642 the application would crash due to NULL pointer dereference.
4643 Affected files silcd/server.c and lib/silcclient/client.c.
4645 * Added `hash' field to the SilcClientConnection to include
4646 the hash function negotiated in the SKE protocol.
4648 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4649 to set the channel founder authentication data. A client can
4650 claim the founder rights later by providing the authentication
4651 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4652 This way the channel founder can regain the channel founder
4653 privileges even it is left the channel. This works only on
4654 local server and the client must be connected to the same
4655 server to be able to regain the founder rights. Updated the
4656 protocol specs accordingly.
4658 Added support to the CMODE command in the client to set the
4659 founder auth data. Read the README to see how to set it.
4661 Added support to the CUMODE command to claim the founder
4662 rights. Read the README to see how to do it.
4664 Added support for the founder authentication to the Channel
4665 Entry in the server. Affected file silcd/idlist.h.
4667 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4668 server's CMODE command. Affected file silcd/command.c.
4670 * Added the following new functions into lib/silccore/silcauth.[ch]:
4671 silc_auth_get_method and silc_auth_get_data.
4673 * The server now saves the remote hosts public key to the
4674 SilcIDListData pointer. Affected file silcd/protocol.c.
4676 * The normal server now does not remove the channel entry from
4677 the cache if the founder authentication data is set. It used
4678 to remove it if the founder was the last one on the channel on
4679 the server and left the channel. The auth data is saved and
4680 if the channel is re-joined later the old entry is used with
4681 the old auth data. Affected files silcd/command_reply.c and
4684 * Removed the `pkcs' field from the SilcIDListData structure
4685 in the server; it is not used. Affected file silcd/idlist.h.
4687 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Fixed packet processing on slow links. Partial packets were
4690 never re-processed because the incoming data buffer was cleared
4691 by the application. Application must not directly clear the
4692 sock->inbuf, the packet processing routines handle it. Fixed
4693 this in client library and in server.
4695 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Fixed the WHOIS and IDENTIFY send reply function to really
4698 check whether to send list or just one entry. Affected file
4701 * Cleaned up the LEAVE command's channel key distribution. The
4702 affected file silcd/command.c.
4704 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4705 can enforce the channel mode as well. In that case the ID
4706 includes the ID of the server. The code now enforces the
4707 mode change if the router have different mode than the server.
4709 * The notify client operation with CMODE_CHANGE notify can now
4710 return NULL client_entry pointer if the CMODE was not changed
4711 by client. Application must check for this.
4713 * Added <Server ID> argument to INFO command to support server
4714 info fetching by Server ID.
4716 * Added silc_server_announce_get_channel_users to get assembled
4717 packets of channel users of the specified channel. Affected
4718 file silcd/server.[ch].
4720 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4721 was freed underneath the ID Cache.
4723 * Re-announce clients when the server received CHANNEL_CHANGE
4724 notify from the router. Affected file silcd/packet_send.c.
4726 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4729 crashed since it did not handle the fact that there is no cipher
4730 called "3" and didn't check the error condition. Now fixed.
4732 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4733 flag. It can be used to send message requests.
4735 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Implemented the RESTART command in the client.
4739 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4740 notice type messages. Added notice printing to the user
4743 * The channel keys are not re-generated if the channel's mode
4744 is PRIVKEY, ie private key on the channel exists. Affected
4745 files silcd/server.c and silcd/command.c.
4747 * Fixed a little bug in channel message delivery when channel
4748 private keys are set in the server. Affected file is
4749 silcd/packet_send.c.
4751 * Changed the setting on channel->on_channel = TRUE from the
4752 silc_client_save_channel_key to the JOIN command reply. The
4753 key payload is not received if the private channel key is set.
4754 Affected file lib/silcclient/command_reply.c and the
4755 lib/silcclient/client_channel.c.
4757 * When the CMODE_CHANGE notify is sent and the channel private
4758 key mode is removed the channel key must be re-generated in
4759 other cells as well. Added this support for the router in the
4760 silcd/packet_receive.c.
4762 * Added new local command NOTICE to send notice message on
4763 channel. Affected file silc/local_command.[ch].
4765 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Added new local command ME to the client. It is used to send
4768 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4769 some action. Affected file silc/local_command.[ch].
4771 * Changed channel_message and private_message client operations
4772 to deliver the message flags to the application. Added also
4773 the `flags' arguments to the silc_client_send_channel_message
4774 and silc_client_send_private_message functions. Affected file
4777 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Redefined the Private Message Payload to support private message
4780 keys and to support the new private message flags. Updated
4781 the protocol specs. Flags makes it possible to have for example
4782 CTCP style messages.
4784 * Added new type SilcPrivateMessagePayload and defined an API
4785 for it in the lib/silcclient/silcprivate.[ch].
4787 * Tested private message private keys successfully. Tested the
4788 private message key set, unset and list commands with the new
4791 * Redefined the Channel Message Payload to include the channel
4792 message flags (equal with private message flags) to support
4793 for example CTCP style messages.
4795 * Defined some of the message (for channel and private message)
4796 flags. Updated the protocol specs and added the flags to the
4797 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4799 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Added SilcKeyAgreementStatus type to the key agreement routines
4802 to indicate the current status and error if one occured.
4803 The status types are defined in the lib/silcclient/silcapi.h.
4805 * Added new local command KEY that is used to set and unset private
4806 keys for channels, set and unset private keys for private messages
4807 with remote clients and to send key agreement requests and
4808 negotiate the key agreement protocol with remote client. The
4809 key agreement is supported only to negotiate private message keys,
4810 it currently cannot be used to negotiate private keys for channels,
4811 as it is not convenient for that purpose.
4813 * Fixed a minor pending callback setting bug in the function
4814 silc_client_get_client_by_id_resolve, now the function works.
4815 Affected file lib/silcclient/idlist.c.
4817 * Added function silc_net_get_local_port to get local bound
4818 port by socket. Added to lib/silcutil/silcnet.[ch].
4820 * Added `sockets' and `sockets_count' fields to the SilcClient
4821 object. They hold the sockets of the listenning sockets in
4822 the client. Listenning sockets may be for example the key
4823 agreement server. Affected file lib/silcclient/client.[ch].
4824 Added functions the silc_client_add_socket and the
4825 silc_client_del_socket. They are exported to the application
4828 * Added ~./silc/clientkeys to support other client's public keys.
4830 * Renamed verify_server_key client operation to verify_public_key
4831 and added one argument to indicate the type of the connection
4832 (server, client etc.).
4834 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Added silc_server_connection_auth_request to handle the
4837 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4838 silcd/packet_receive.[ch].
4840 * Added silc_server_send_connection_auth_request into the
4841 silcd/packet_send.c to send the connection auth request packet.
4843 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4846 * Fixed the public key authentication in responder side in the
4847 server. The `auth_data' pointer includes the SilcPublicKey
4848 not the path to the public key. Affected file silcd/protocol.c.
4850 * Implemented the public key authentication in the initiator side
4851 in the server. Affected file silcd/protocol.c.
4853 * Removed the [RedirectClient] config section from the server
4854 configuration. Is not needed and I don't want to implement it.
4856 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Cleaned up the CMODE command in the server. It now works
4859 correctly and supports all the modes defined in the protocol.
4860 Affected file is silcd/command.c.
4862 * Added `hmac_name' field to the SilcChannelEntry in the server
4863 to hold the default HMAC of the channel. It can be set when
4864 creating the channel (with JOIN command). Affected files
4867 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4868 type to indicate the change of the current cipher and hmac
4869 on the channel. Client can safely ignore the <cipher> argument
4870 (if it chooses to do so) since the CHANNEL_KEY packet will
4871 force the channel key change anyway. The <hmac> argument is
4872 important since the client is responsible of setting the new
4873 HMAC and the hmac key into use.
4875 * Fixed the CMODE command in the client library as well.
4877 * Tested CMODE command in router environment successfully.
4879 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Show the version of the remote client (or server) when connecting
4882 to the server. It is logged to the log file. Affected file
4883 is silcd/protocol.c.
4885 * Fixed the KILLED notify handling in the client library. The
4886 client must be removed from all channels when receiving the
4889 Also, do not remove the client entry when giving the KILL
4890 command but when the KILLED notify is received.
4892 * Removed silc_idlist_find_client_by_nickname from the server.
4893 Not needed anymore. Affected files silcd/idlist.[ch].
4895 * Implemented the CHANNEL_CHANGE notify type handling to the
4896 server. Affected file silcd/server.c.
4900 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added silc_server_send_notify_invite to send the INVITE
4903 notify between routers.
4905 * Implemented the INVITE command correctly to the server.
4907 * Implemented the INVITE notify type handling in the server.
4909 * Implemented the INVITE command to the client library and on the
4912 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added function silc_server_get_client_resolve to find the
4915 client entry by ID from all ID lists and then resolve it
4916 (using WHOIS) if it cannot be found. Affected file is
4919 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Implemented the BAN command to the client library.
4923 * The JOIN command in the server now checks the invite list
4926 * Changed the silc_command_reply_payload_encode_va and the
4927 silc_command_payload_encode_va to support that if argument is
4928 NULL it ignores and checks the next argument. Affected file
4929 lib/silccore/silccommand.c.
4931 * Added silc_server_send_notify_ban to send the BAN notify
4932 type between routers.
4934 * Chaned the silc_notify_payload_encode to support that if
4935 argument is NULL it ignores and checks the next argument.
4936 Affected file lib/silccore/silcnotify.c.
4938 * Tested ban lists in router environment successfully.
4940 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Implemented BAN command to the server, in silcd/command.[ch].
4944 * Removed the BAN and INVITE_LIST modes from the CMODE command
4947 * Added function silc_string_match to regex match two strings.
4948 Affected files lib/silcutil/silcutil.[ch].
4950 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Redefined parts of the SilcChannelEntry in the server to support
4953 the new ban and invite lists.
4955 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Redefined the INVITE command. The same command can be used to
4958 invite individuals to the channel but also to manage the invite
4959 list of the channel (to add to and remove from the invite list).
4960 Updated the protocol specs.
4962 * Added new command SILC_COMMAND_BAN that can be used to manage
4963 the ban list of the channel. Updated the protocol specs.
4965 * Removed the channel modes: the SILC_CMODE_BAN and the
4966 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4967 in the CMODE command. The equivalent features are now available
4968 using INVITE and BAN commands. Updated the protocol specs.
4970 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4971 in the network about change in the current ban list. The notify
4972 type is not used by the client.
4974 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4975 support the invite lists.
4977 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Added new function silc_string_regexify that converts string
4980 including wildcard characters into regex string that can
4981 be used by the GNU regex library. Added into the file
4982 lib/silcutil/silcutil.[ch].
4984 Added silc_string_regex_combine to combine to regex strings
4985 into one so that they can be used as one regex string by
4986 the GNU regex library. Added into the file
4987 lib/silcutil/silcutil.[ch].
4989 Added silc_string_regex_match to match two strings. It returns
4990 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4992 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Imported GNU regex to the soruce tree into lib/contrib.
4995 Fixed some compiler warning from the regex.c.
4997 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Fixed MOTD command in the server to work in router environment.
5001 * Fixed the MOTD command in the client library to support
5002 the server argument in the command.
5004 * Added `nickname_len' argument to the silc_idlist_add_client
5005 in the server, as the `nickname' argument may be binary data
5008 * Added silc_idlist_get_channels to return all channels from
5011 * Implemented LIST command to the server. Affected file is
5014 * Implemented the LIST command to the client library and on the
5017 * Added [<user count>] argument to the LIST command reply.
5018 With private channels the user count is not shown.
5020 * Updated TODO and README.
5022 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * The client entry's data.registered must be TRUE even with
5025 global client entry on global client list. The data.registered
5026 is used to check whether the client is anymore in the network,
5027 for example with WHOWAS command so it must be valid.
5029 * Fixed the WHOWAS command in the server. It now actually works
5030 in router environment. Added function into silcd/command_reply.c
5031 silc_server_command_reply_whowas_save.
5033 * Added silc_idlist_purge function to the silcd/idlist.c
5034 to periodically purge the ID Cache.
5036 * Fixed INFO command in the server. It works now in router
5037 environment. Added <server name> argument to the INFO command
5038 reply. Updated the protocol specs.
5040 * Fixed minor bug in silc_idcache_purge to not purge if the
5041 expire value is zero.
5043 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5044 they were buggy because of the WHOWAS information.
5046 * Fixed local command MSG to handle the async resolving of
5047 the remote client properly. It used to fail the first MSG.
5048 Affected file silc/local_command.c.
5050 * Added `data_len' field to SilcIDCache context.
5052 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Update TODO. Todo in commands in the server.
5056 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5059 used by routers as broadcast packet to inform other routers
5060 about the changed user mode.
5062 Implemented the notify handling in the server. Affected file is
5063 silcd/packet_receive.c. Added the function
5064 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5066 * Added new generic Channel Payload and deprecated the New Channel
5067 Payload. The New Channel Payload is now the generic Channel
5070 * Added new argument `mode' to the silc_server_send_new_channel
5071 as it is required in the Channel Payload now.
5073 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5074 and created a new and real SilChannelPayload to represent the
5075 new generic Channel Payload. Implemented the encode/decode
5076 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5078 * Added silc_server_get_client_channel_list to return the list
5079 of channels the client has joined for WHOIS command reply.
5080 Affected file silcd/server.[ch].
5082 * Implemented the channel list sending in the WHOIS command reply
5083 in server and in the client.
5085 Implemented the channel list displaying on the user interface
5086 as well. Affected file silc/client_ops.c.
5088 * Added silc_channel_payload_parse_list to parse list of Channel
5089 Payloads. It returns SilcDList list of SilcChannelPayloads.
5090 Client for example can use this function to parse the list of
5091 channels it receives in the WHOIS command reply. The caller
5092 must free the list by calling silc_channel_payload_list_free.
5093 Affected files lib/silccore/silcchannel.[ch].
5095 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Added one new argument <user mode> to the WHOIS command reply
5098 to return the mode of the user in SILC. Updated the protocol
5101 Implemented it to the server and client.
5103 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Fixed the mode printing on the user interface on joining.
5106 Affected file silc/client_ops.c.
5108 * Implemented the UMODE command and user modes in general to the
5109 client library and to the user interface.
5111 * Implemented the UMODE command to the server.
5113 * The server now sends UNKNOWN_COMMAND error status if client sends
5114 unknown command. Affected file silcd/command.c.
5116 * All server commands now handle the command identifier the right
5117 way when sending the command reply to the client. The client can
5118 use to identify the command replies with the identifier.
5120 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Added silc_server_get_client_route to resolve the route to
5123 the client indicated by the client ID. Affected file is
5126 * Added silc_server_relay_packet as general function to relay
5127 packet to arbitrary destination. This deprecates functions
5128 like _send_private_message_key, _relay_notify etc. Affected
5129 file is silcd/packet_send.[ch].
5131 Removed silc_server_send_key_agreement,
5132 silc_server_send_private_message_key and
5133 silc_server_packet_relay_notify functions from the file
5134 silcd/packet_send.[ch].
5138 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5139 server. Affected file silcd/packet_receive.[ch].
5141 * Implemented the KILL command to the client. Implemented the
5142 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5143 Affected files lib/silcclient/command[_reply].c and
5144 lib/silcclient/client_notify.c. Implemented the KILL notify
5145 printing in the user inteface.
5147 * Fixed a lot silc_parse_nick memory leaks from the client
5148 library in the file lib/silcclient/command.c.
5150 * Changed the silc_server_send_notify_on_channels's `sender'
5151 argument from SilcSocketConnection to SilcClientEntry to
5152 check the sender as entry and not as connection object and not
5153 to send to the client provided as argument. The affected file
5154 is silcd/packet_send.[ch].
5156 * The notify packets that are destined directly to the client used
5157 to not to be processed by the server. Now changed that and the
5158 server processes all notify packets. After relaying the packet
5159 to the client the notify packet is processed in the server.
5161 * The silc_server_free_client_data now checks whether there is
5162 pending outgoing traffic for the client and purges the data to
5163 the network before removing the client entry.
5165 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5168 an client is killed from the SILC Network. Updated the protocol
5171 Added new function silc_server_send_notify_killed to the
5172 silcd/packet_send.[ch].
5174 * Added function silc_server_packet_relay_notify to relay notify
5175 packets that are destined directly to a client. In this case
5176 the server does not process the notify packets but merely relays
5177 it to the client. Affected file silcd/packet_send.[ch].
5179 Added also silc_server_packet_process_relay_notify to check
5180 whereto relay the notify. Affected file is
5181 silcd/packet_receive.[ch].
5183 * Implemented the KILL command to the server.
5187 * Added the backup schema desgined last fall to the protocol
5188 specs for everyone to see. The specification is in the
5189 *-spec-xx.txt draft and the packet type definitions for the
5190 backup routers is in *-pp-xx.txt draft. Thusly, added also
5191 new packet type SILC_PACKET_CELL_ROUTERS.
5193 * A big security problem in the implementation discovered. The
5194 signoff of an client did not cause new channel key generation
5195 which it of course should've done. The channel keys must be
5196 always re-generated when client leaves (or signoffs) the channel.
5197 The silc_server_remove_from_channels funtion now handles
5198 the channel key re-generation.
5200 * Added `sender' argument to the silc_server_send_notify_on_channels
5201 to not to send the client provided as argument. Affected file
5202 silcd/packet_send.[ch].
5204 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Implemented OPER and SILCOPER commands into the server and
5209 * Added silc_auth_verify and silc_auth_verify_data to verify
5210 the authentication directly from the authentication payload.
5211 It supports verifying both passphrase and public key based
5212 authentication. Affected file lib/silccore/silcauth.[ch].
5214 * Added `hash' field to the SilcIDListData structure. It is the
5215 hash negotiated in the SKE protocol. Affected file is
5218 * Slight redesigning of the SilcAuthPayload handling routines.
5219 Do not send SilcPKCS but SilcPublicKey as argument.
5221 * Implemented the public key authentication support to the
5222 serverconfig. The public key is loaded from the provided path
5223 and saved as authentication data to void * pointer. Thus,
5224 changed the unsigned char *auth_data to void *auth_data;
5226 * Fixed SHUTDOWN command to send the reply before the server
5227 is shutdown. :) Affected file silcd/command.c.
5229 * Fixed fatal bug in CONNECT command. The hostname was invalid
5230 memory and server crashed. Affected file silcd/command.c.
5232 * Fixed fatal bug in CLOSE command. The server_entry became
5233 invalid but was referenced later in the command. Affected file
5236 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Fixed fatal bug in failure packet handling. Server ignored
5239 the failure and thus crashed when it came.
5243 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5246 that the command may be executed only once in (about) 2 seconds.
5247 The old SILC_CF_LAG flag is same but allows command bursts up
5248 to five before limiting.
5250 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5251 server code. Various commands now includes the CF_LAG_STRICT
5252 flag to disallow any kind of miss-use of the command.
5254 * Fixed the silc_buffer_unformat to not to allocate any data
5255 if the length of the data is zero. It used to allocate the
5256 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5258 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Changed the format of AdminConnection configuration section
5261 in the server. Added username of the admin to the format.
5262 Affected files silcd/serverconfig.[ch].
5264 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5265 to return admin configuration data by host, username and/or
5268 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Implemented WHOWAS command to the server. Added the functions:
5272 silc_server_command_whowas_parse,
5273 silc_server_command_whowas_send_reply,
5274 silc_server_command_whowas_from_client and
5275 silc_server_command_whowas_from_server
5277 * Added <Client ID> argument to the WHOWAS command reply. Updated
5278 the protocol specs accordingly.
5280 * Implemented WHOWAS command and command_reply to the client
5283 Implemented the WHOWAS printing on the user interface.
5285 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Added new argument to the WHOWAS command reply, the real name.
5288 It is an optional argument. Updated the protocol specs.
5290 * Added SilcIDCacheDestructor callback that is registered when
5291 the SilcIDCache is allocated. The callback is called when
5292 an cache entry in the ID Cache expires, or is purged from the
5293 cache. Added into lib/silccore/idcache.[ch].
5295 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5296 to destruct the client entries when the cache entry expires.
5297 Other ID Cache's in server and in the client library ignores
5300 * If the ID Cache entry's `expire' field is zero then the entry
5301 never expires. Added boolean `expire' argument to the
5302 silc_idcache_add function in the lib/silccore/idcache.[ch].
5303 If it is TRUE the default expiry value is used.
5305 * Added silc_server_free_client_data_timeout that is registered
5306 when client disconnects. By default for 5 minutes we preserve
5307 the client entry for history - for WHOWAS command.
5309 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5311 * Added support to the server to enforce that commands are not
5312 executed more than once in 2 seconds. If server receives
5313 commands from client more frequently, timeout is registered
5314 to process the commands. Affected file silcd/command.c.
5315 Added new function silc_server_command_process_timeout.
5317 * Changed NICK_NOTIFY handling in client library to check that
5318 if the client's nickname was changed, so there is no need to
5319 resolve anything from the server.
5321 * Removed error printing from the WHOIS and IDENTIFY commands.
5322 If error occurs then it is ignored silently in the client library.
5323 The application, however, may map the received error to
5324 human readable error string. The application currently maps
5325 the NO_SUCH_NICKNAME error to string.
5327 * Made the command status message public to the application. Moved
5328 them from lib/silcclient/command_reply.c to
5329 lib/silcclient/command_reply.h. The application can map the
5330 received command status to the string with the
5331 silc_client_command_status_message function.
5333 * Added check to the server to check that client's ID is same
5334 as the Source ID in the packet the client sent. They must
5337 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Added dist-bzip hook to the Makefile.am to make bzip2
5340 compressed distributions.
5342 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5344 * Server now enforces the maximum length for the nickname and
5345 the channel as protocol specification dictates. 128 bytes for
5346 nickname and 256 bytes for channel name.
5348 * Moved the WHOIS printing to the application. The client libary
5349 does not print out the WHOIS information anymore, the application
5350 must do it. Renamed silc_client_command_reply_whois_print to
5351 the silc_client_command_reply_whois_save.
5353 The client's idle time is also sent to the application now, and
5354 the idle is shown on screen.
5356 * Added silc_client_command_reply_identify_save to save the
5357 received IDENTIFY entries.
5359 * Do not check for channel private keys in message sending and
5360 reception if the channel does not have the PRIVKEY mode set.
5361 Affected file lib/silclient/client_channel.c.
5363 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5366 just surfaced after chaning the JOIN procedure.
5368 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Added silc_client_get_clients_by_list to get client entries
5371 from Client ID list, that is returned for example by JOIN
5372 and USERS command replies. The application should use this
5373 function for example when JOIN command reply is received to
5374 resolve the clients already on the channel (library does not
5375 do that anymore as USERS command reply is not used in the JOIN
5376 procedure anymore). Affected files lib/silcclient/silcapi.h and
5377 lib/silcclient/idlist.c.
5379 * JOIN command reply and USERS command reply returns now SilcBuffer
5380 pointers instead of unsigned char pointers when returning
5381 the client list and mode list.
5383 * Added <Client ID> argument to the JOIN command reply, mainly
5384 for the server to identify for which client the command was
5385 originally sent. Updated protocol specs accordingly.
5387 * Added SilcDlist private_key pointer to the SilcChannelEntry
5388 in the client to support the channel private keys. Affected
5389 file is lib/silcclient/idlist.h.
5391 * Added SilcChannelPrivateKey argument to the function
5392 silc_client_send_channel_message so that application can choose
5393 to use specific private ke if it wants to. If it is not provided,
5394 the normal channel key is used, unless private keys are set.
5395 In this case the first (key that was added first) is used
5396 as the encryption key.
5398 * Implemented the support for channel private key handling.
5399 Implemented the following functions:
5401 silc_client_add_channel_private_key,
5402 silc_client_del_channel_private_keys,
5403 silc_client_del_channel_private_key,
5404 silc_client_list_channel_private_keys and
5405 silc_client_free_channel_private_keys
5407 Affected file lib/silcclient/client_channel.c.
5409 * Added the support for the private keys in the channel message
5410 sending and encryption and in the message reception and
5411 decryption. Affected funtions are
5412 silc_client_send_channel_message and silc_client_channel_message.
5414 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Added SKE's key verify callback to the client library's
5417 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5419 * Removed the statement that server (or router) must send USERS
5420 command reply when joining to the channel so that the client
5421 knows who are on the channel. Instead, the client list and
5422 client's mode list is now sent in the JOIN command reply to the
5423 client who joined channel. This is better solution.
5425 * Added function silc_server_get_users_on_channel and function
5426 silc_server_save_users_on_channel to the silcd/server.[ch].
5428 * Removed function silc_server_command_send_users from the
5431 * Do not show topic on the client library anymore. The topic is
5432 sent in the command reply notify to the application and the
5433 application must show the topic now.
5435 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Added client searching by nickname hash into the IDENTIFY and
5438 WHOIS commands in the server as they were clearly missing from
5439 them. Affected file is silcd/command.c.
5441 * Fixed a bug in private message receiving in the client library.
5442 The remote ID was freed and it wasn't supposed, now it is
5445 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Minor fix to the channel payload; allocate the data area, as it
5448 needs to be of specific length.
5450 * If the key agreement port is zero then the operating
5451 system will define the bound port. Affected files are
5452 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5454 * Added new function silc_channel_payload_decrypt into the file
5455 lib/silccore/silcchannel.[ch].
5457 * Moved the channel message etc, check from silc_packet_decrypt
5458 to applications. The library calls now a generic
5459 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5460 when the packet is either normal or special. This was done to
5461 allow more wide range of checking that was not allowed when
5462 the code was in library. Now applications can do virtually any
5463 checks to the packet and return to the library the decision how
5464 the packet should be processed. Affected files are
5465 lib/silccore/silcpacket.[ch].
5467 Added silc_server_packet_decrypt_check to the server and
5468 silc_client_packet_decrypt_check to the client library.
5470 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5471 to send with specified source and destination information.
5473 * Channel message delivery between routers was broken after the
5474 channel key distribution was fixed earlier. The channel key
5475 was used be to distributed to other routers as well which is not
5476 allowed by the protocol. Now this is fixed and channel keys
5477 really are cell specific and the channel message delivery between
5478 routers comply with the protocol specification.
5480 * Fixed various commands in server to check also the global list
5481 for the channel entry and not just the local list. The affected
5482 file silcd/command.c.
5484 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Added assert()s to buffer formatting and unformatting routines
5487 to assert (if --enable-debug) when error occurs. Affected
5488 file: lib/silcutil/silcbuffmt.c.
5490 * Changed to auto-reconnect to check whether the remote host is
5491 router and register the re-connect timeout if it is. It used
5492 to check that whether we are normal server, but router must do
5493 auto-reconnect with another router as well. Affected file
5496 * Removed the [<key len>] option from CMODE command as the cipher
5497 name decides the key length, nowadays. See the defined ciphers
5498 from the protocol specification.
5500 * Added [<hmac>] option to the CMODE command to define the HMAC
5501 for the channel. Added SILC_CMODE_HMAC channel mode.
5503 * Added [<hmac>] option for the JOIN command so that user can
5504 select which HMAC is used to compute the MACs of the channel
5507 * Added Hmac field to the Channel Message Payload. The integrity
5508 of plaintext channel messages are now protected by computing
5509 MAC of the message and attaching the MAC to the payload. The
5510 MAC is encrypted. Now, it is clear that this causes some
5511 overhead to the size of the packet but rationale for this is that
5512 now the receiver can verify whether the channel message decrypted
5513 correctly and also when private keys are set for the channel the
5514 receiver can decrypt the packet with several keys and check from
5515 the MAC which key decrypted the message correctly.
5517 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5518 lib/silccrypt/silccipher.[ch].
5520 * Added silc_hash_len to return the digest length into the
5521 lib/silcrypt/silchash.[ch].
5523 * Rewrote parts of Silc Channel Payload interface in the
5524 lib/silccore/silcchannel.[ch]. The encode function now also
5525 encrypts the packet and parse function decrypts it.
5527 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Fixed a minor formatting bug in the SKE's key material processing.
5530 It actually might have processed the keys wrong way resulting
5533 * Redefined the mandatory HMAC algorithms and added new algorithms.
5534 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5535 and hmac-md5 truncated to 96 bits. The mandatory is now
5536 hmac-sha1-96. Rest are optional (including the one that used
5537 to be mandatory). Rationale for this is that the truncated HMAC
5538 length is sufficient from security point of view and can actually
5539 make the attack against the HMAC harder. Also, the truncated
5540 HMAC causes less overhead to the packets. See the RFC2104 for
5543 * Added new [hmac] configuration section. The SKE used to use
5544 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5545 is of course wrong. The official names that must be proposed in
5546 the SKE are the ones defined in the protocol specification
5547 (hmac-sha1-96 for example). The user can configure any hmac
5548 using any hash function configured in the [hash] section. At
5549 least, the mandatory must be configured.
5551 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5553 * Added HMAC list to the SKE proposal list. It has now both
5554 hash algorithm list and HMAC list. This makes the protocol
5555 incompatible with previous versions. The SKE now seems to work
5556 the way it is supposed to work, for the first time actually.
5558 * Defined plain Hash algorithms to the protocol specification.
5561 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Implemented support for key agreement packets into the server.
5564 Added functions silc_server_key_agreement and
5565 silc_server_send_key_agreement. Other than these functions,
5566 server has nothing to do with this packet.
5568 * Added support for private message key packets into the server.
5569 Added functions silc_server_private_message_key and
5570 silc_server_send_private_message_key.
5574 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5575 called in the protocol's final callback instead in the END
5576 protocol state. This makes a little more sense and in the same
5577 time in client we can use the same protocol routines for normal
5578 key exchange and to key agreement packet handling as well.
5580 * Added to both client's and server's KE protocol context the
5581 SilcSKEKeyMaterial pointer to save the key material. We will
5582 bring the key material to the protocol's final callback by doing
5583 this. The final callback must free the key material.
5585 * Added SKE's packet_send callback into client's KE protocol
5586 context so that the caller can choose what packet sending function
5587 is used. This way we can use different packet sending when
5588 doing normal SKE when doing key agreement packet handling (in
5589 the key agreement packet handling we do not want to encrypt
5592 * Implemented the responder side of the key agreement routines
5593 in the client. The client can now bind to specified port and
5594 accept incoming key negotiation. The key material is passed
5595 to the application after the protocol is over.
5597 * Implemented the processing of incoming Key Agreement packet
5598 in the client. Added function silc_client_key_agreement to
5601 * Implemented the intiator side of the key agreement routines
5602 in the client. The client can now initiate key agreement with
5603 another remote client. The key material is passed to the
5604 application after the protocol is over.
5606 * Created client_keyagr.c to include all the key agreement
5609 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5610 SILC_TASK_CALLBACK except that it is not static.
5612 * Created client_notify.c and moved the Notify packet handling
5613 from the client.[ch] into that file.
5615 * Created client_prvmsg.c and moved all private message and
5616 private message key routines from the client.[ch] into that file.
5618 * Create client_channel.c and moved all channel message and
5619 channel private key routines from the client.[ch] into that file.
5621 * Changed silc_client_get_client_by_id_resolve to resolve with
5622 WHOIS command instead of IDENTIFY command, in the file
5623 lib/silclient/idlist.c.
5625 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Implemented the SKE's responder side to the Client library.
5629 * When FAILURE is received to the protocol do not trust it
5630 blindly. Register a timeout to wait whether the remote closes
5631 the connection as it should do it, only after that process the
5632 actual failure. This was changed to both client and server.
5634 * Added client_internal.h to include some of the structures
5635 there instead of client.h in lib/silcclient/.
5637 * Added function silc_task_unregister_by_callback to unregister
5638 timeouts by the callback function.
5640 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Some "Incomplete WHOIS info" errors has been appearing on the
5643 log files. Took away the entry->userinfo check from WHOIS
5644 reply sending. The entry->userinfo is now " " if client did not
5645 provide one. I thought this was fixed earlier but something
5646 is wrong still. Let's see if the error still appears.
5648 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Fixed a minor bug in the login when the channel key is
5651 re-generated in the server. It used to generate the key in
5652 wrong order and thus caused problems in the channel traffic.
5654 * Fixed a minor bug in channel key distsribution after
5655 KICK command. The key was not sent to the router even though
5658 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Added silc_ske_process_key_material_data as generic routine
5661 to process any key material as the SILC protocol dictates. The
5662 function is used by the actual SKE library but can be used by
5663 applications as well. This relates to the private message keys
5664 and the channel private keys since they must be processed the
5665 same way the normal SILC session keys. The protocol dictates
5666 this. Affected files: lib/silcske/silcske.[ch].
5668 Added also silc_ske_free_key_material to free the
5669 SilcSKEKeyMaterial structure.
5671 * Defined silc_cipher_set_key function to set the key for
5672 cipher without using the object's method function. The affected
5673 files: lib/silccrypt/silccipher.[ch].
5675 * Implemented silc silc_client_add_private_message_key,
5676 silc_client_add_private_message_key_ske,
5677 silc_client_del_private_message_key,
5678 silc_client_list_private_message_keys and
5679 silc_client_free_private_message_keys functions in the
5682 Added functions silc_client_send_private_message_key to send
5683 the Private Message Key payload and silc_client_private_message_key
5684 to handle incoming Private Message Key payload.
5686 * Added Cipher field to the Private Message Key payload to set
5687 the cipher to be used. If ignored, the default cipher defined
5688 in the SILC protocol (aes-256-cbc) is used.
5690 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Removed lib/silcclient/ops.h file.
5694 Redefined parts of the SILC Client Library API. Created new
5695 file silcapi.h that deprecates the ops.h file and defines the
5696 published Client Library API. Defined also private message key
5697 API and channel private key API into the file.
5699 This is the file that the application must include from the
5700 SILC Client Library. Other files need not be included by
5701 the application anymore.
5703 * Added new key_agreement client operation callback and also
5704 defined the Key Agreement library API for the application.
5706 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5709 is used by clients to request key negotiation between another
5710 client in the SILC network. If the negotiation is started it
5711 is performed using the SKE protocol. The result of the
5712 negotiation, the secret key material, can be used for example
5713 as private message key.
5715 Implemented the Key Agreement payload into the files
5716 lib/silccore/silauth.[ch].
5718 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Redefined ciphers for the SILC protocol. Added some new ciphers
5721 and defined the key lengths for the algorithms. Changed the
5722 code accordingly. The default key length is now 256 bits.
5724 * Fixed SKE key distribution function silc_ske_process_key_material
5725 when the key length is more than 128 bits. The default key
5726 length in SILC is now 256 bits.
5728 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5729 to indicate unsupported algorithm.
5731 * Renamed rijndael.c to aes.c and all functions as well.
5733 * Fixed a long standing channel key setting bug in client library.
5734 Weird that it has never surfaced before.
5736 * Fixed bug in channel deletion. If the entire channel is removed
5737 then it must also delete the references of the channel entry
5738 from the client's channel list as the client's channel entry and
5739 the channel's client entry share same memory.
5741 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Implemented CONNECT and SHUTDOWN commands in the client.
5745 * Implemented CLOSE command to the client.
5747 * Added the function silc_idlist_find_server_by_name into the
5748 files silcd/idlist.[ch].
5750 Added the function silc_idlist_find_server_by_conn into the
5751 files silcd/idlist.[ch].
5753 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * DIE command was renamed to SHUTDOWN. Updated the both code
5758 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5759 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5761 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5764 * Added function silc_server_create_connection function to create
5765 connection to remote router. My server implementation actually
5766 does not allow router to connect to normal server (it expects
5767 that normal server always initiates the connection to the router)
5768 so the CONNECT command is only good for connecting to another
5771 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5774 or some other client was kicked from the channel.
5776 Implemented the handling of the notify type to both client
5779 Implemented silc_server_send_notify_kicked to send the KICKED
5780 notify. It is used to send it to the server's primary router.
5782 * Implemented the KICK command into server and client.
5784 * Added `query' argument to the silc_idlist_get_client function
5785 to indicate whether to query the client from server or not if
5788 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5789 to indicate that the client is not channel founder.
5793 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Removed the rng context from SilcPacketContext structure and
5796 changed that the packet routine uses the Global RNG API.
5798 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added support for quit message that client can "leave" on the
5801 channel when it quits the SILC. It is ditributed inside the
5802 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5804 Added silc_server_free_client_data that will take the
5805 signoff message as argument.
5807 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5809 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Updated parts of the protocol specification to keep it up
5814 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5817 payloads in one packet.
5819 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5820 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5821 use now the new List flag.
5823 * Also deprecated the following packet types: REPLACE_ID,
5824 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5826 * Added list support for Notify packet in server.
5828 * Added silc_server_send_notify_channel_change to send the
5829 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5830 the silc_server_send_replace_id.
5832 * Added silc_server_send_notify_nick_change to send the
5833 NICK_CHANGE notify type. Deprecates the function
5834 silc_server_send_replace_id.
5836 * Added silc_server_send_notify_join to send the JOIN notify type.
5837 Deprecates the function silc_server_send_new_channel_user.
5839 * Added silc_server_send_notify_leave to send LEAVE notify type.
5840 Deprecates the function silc_server_send_remove_channel_user.
5842 * Added silc_server_send_notify_cmode and
5843 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5844 types. Deprecates the silc_server_send_set_mode function.
5846 * Added SERVER_SIGNOFF notify type to indicate that server has
5847 quit. This means that all clients on the channel from that
5848 server will drop. This can be also used when netsplit happens.
5850 Deprecated REMOVE_ID packet type since it is not needed anymore
5853 Added silc_server_send_notify_server_signoff to send the
5854 SERVER_SIGNOFF notify type. Deprecates the function
5855 silc_server_send_remove_id.
5857 Added also silc_server_send_notify_signoff to send the
5858 SIGNOFF notify type.
5860 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5861 SILC protocol from this day on. Changed the protocol
5862 specification as well.
5864 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5865 notify type. It is used between routers to notify about
5866 topic changes on a channel.
5868 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5871 * Partly updated the protocol specification to comply with the
5872 changes now made. It is still though a bit outdated.
5874 * The JOIN notify type now takes one extra argument <Channel ID>.
5875 The packet used to be destined to the channel but now the
5876 JOIN type may be sent as list thus it is impossible to
5877 destine it to any specific channel. By adding this argument
5878 it is again possible.
5880 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Added CREDITS file. The CHANGES and CREDITS file will appear
5883 in the distribution as well.
5885 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5888 types in the server's silcd/packet_receive.c.
5890 * Implemented CMODE and CUMODE to work in router environment.
5892 * Fixed minor encoding and decoding buglet from the
5893 lib/silccore/silcmode.c.
5895 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5898 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5900 * Changed all SilcConfigServer* and silc_config_server* to
5901 SilcServerConfig* and silc_server_config*, respectively.
5904 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Associated the ID (client or server ID) to the Authentication
5907 Payload to avoid any possibility of forging. Updated the
5908 protocol specification and the code accordingly.
5910 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * The RSA key length is now save to the RsaKey context in the
5913 key generation process in lib/silccrypt/rsa.c. The key length
5914 is now used to figure out the maximum size of the block allowed
5915 to be encrypted/signed.
5917 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5918 is equivalent to the silc_mp_mp2bin but does not allocate any
5921 * Changed silc_mp_mp2bin API to take length argument. If it is
5922 non-zero then the buffer is allocated that large. If zero, then
5923 the size is approximated using silc_mp_sizeinbase, which however
5926 * Created Global RNG API which is global RNG that application can
5927 initialize. After initializing, any routine anywhere in the
5928 code (including library) can use RNG without allocating a new
5929 RNG object. This was done to allow this sort of use of the
5930 RNG in code that has no chance to allocate RNG object. All
5931 applications currently allocate this and many routines in the
5932 library use this. Affected file lib/silccrypt/silcrng.[ch].
5934 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5935 it to use the Global RNG API.
5937 * Defined Authentication Payload into protocol specification that
5938 is used during SILC session to authenticate entities. It is
5939 used for example by client to authenticate itself to the server
5940 to obtain server operator privileges.
5942 Implemented this payload into the lib/silccore/silcauth.[ch].
5943 Implemented also routines for public key based authentication
5944 as the new protocol specification dictates.
5946 Moved definitions of different authentication methods from
5947 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5949 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5950 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5951 silc_pkcs_verify_with_hash functions into the file
5952 lib/silccrypt/silcpkcs.[ch].
5954 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * The client entry's userinfo pointer must be always valid.
5957 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5958 will fail since it requires the userinfo. Now, the userinfo
5959 is allocated as "" if actual userinfo does not exist. Actually,
5960 it must exist and it is totally Ok to drop client connections
5961 that does not announce the userinfo. However, we will make
5962 this workaround for now.
5964 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5965 to return the remote port by socket.
5967 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5970 SILC_SERVER_PENDING_EXEC and added an new macro
5971 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5972 data or when error occurs while processing the pending command.
5974 Added new argument `destructor' into silc_server_command_pending
5975 and to the SilcServerCommandPending object. This destructor is
5976 now called after calling the pending callback or if error occurs
5977 immediately. If error occurs the actual pending callback won't
5978 be called at all - only the destructor. The destructor may be
5979 NULL if destructor is not needed.
5981 All this applies for client library code as well. Similar
5982 changes were made there as well for the pending commands.
5984 In the client, the application must now allocate the
5985 SilcClientCommandContext with the silc_client_command_alloc
5988 * Added reference counter to the SilcServerCommandContext. Added
5989 function silc_server_command_alloc and silc_server_command_dup
5992 Same type of functions added to the client library for the same
5995 * Removed the cmd_ident from IDListData away since it is now
5996 global for all connections. It is the command identifier used
5997 in command sending and with pending commands. The affected file
6000 * Added reference counter to the SilcSocketConnection objecet to
6001 indicate the usage count of the object. The object won't be
6002 freed untill the reference counter hits zero. Currently only
6003 server uses this, and client ignores it. The client must be
6004 set to use this too later. The affected files are
6005 lib/silccore/silcsockconn.[ch]. Added also the function
6006 silc_socket_dup to increase the reference counter.
6008 This was mainly added because it is possible that the socket
6009 is removed underneath of pending command or other async
6010 operation. Now it won't be free'd and proper DISCONNECTING
6011 flags, etc. can be set to avoid sending data to connection that
6012 is not valid anymore.
6014 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6015 the connection. After that it sets SILC_SET_DISCONNECTED.
6016 It is, however, possible that the socket data is not still freed.
6017 The silc_server_packet_process now checks that data is not
6018 read or written to connection that is DISCONNECTED. The socket
6019 get's freed when the reference counter hits zero.
6021 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Changed the client operation API: channel_message operation's
6024 `sender' is now the client entry of the sender, not the nickname
6025 and the `channel' is the channel entry, not the channel name.
6027 In the private_message operation the `sender' is now also the
6028 client entry of the sender not the nickname.
6030 Affected file is lib/silcclient/ops.h and all applications
6031 using the client operations.
6033 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Moved the calling of ops->connect() from connect_to_server_final
6036 into receive_new_id functin since that is the point when the
6037 client is actually allowed to send traffic to network. The
6038 affected file is lib/silcclient/client.c.
6040 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6043 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6044 (if needs broadcasting) instead of broadcasting the packets one
6045 by one which would make a burst in the network traffic.
6047 * Added `broadcast' argument to the functions in silcd/server.[ch]
6048 silc_server_create_new_channel[_with_id] to indicate whether
6049 to send New Channel packet to primary router.
6051 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added new function into the silcd/server.[ch] files:
6054 silc_server_create_new_channel_with_id to create new channel with
6055 already existing Channel ID.
6057 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6058 lib/silccore/silcpacket.h. This packet is used t send list of
6059 Set Mode payloads inside one packet. Server uses this to set
6060 the modes for the channels and clients on those channels, that it
6061 announced to the router when it connected to it. The protocol
6062 specification has been updated accordingly.
6064 * The silc_server_new_channel did not handle the packet coming
6065 from normal server as it normally does not send that. However,
6066 when it announces its channels it does send it. Implemented
6067 the support for that.
6069 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6070 into the file lib/silccore/id.h.
6072 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6074 * Fixed memory leaks in the functions silc_idlist_del_client,
6075 silc_idlist_del_channel and silc_idlist_del_server in the file
6076 silcd/idlist.c. All of those leaked like a sieve.
6078 * Fixed some small memory leaks in the client's function
6079 silc_client_notify_by_server.
6081 * Added functions into silcd/server.c: silc_server_announce_clients,
6082 silc_server_announce_channels and silc_server_announce_server.
6083 These functions are used by normal and router server to announce
6084 to its primary router about clients, channels and servers (when
6085 router) that we own. This is done after we've connected to the
6088 These functions effectively implements the following packet types:
6089 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6090 and SILC_PACKET_NEW_ID_LIST.
6092 * Added new functions into the silcd/packet_receive.[ch]:
6093 silc_server_new_id_list, silc_server_new_channel_list and
6094 silc_server_new_channel_user_list to handle the incoming
6095 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6097 * Added support of changing Channel ID in the function
6098 silc_server_replace_id. If the server that announces a channel
6099 to the router already exists in the router (with same name but
6100 with different Channel ID), router is responsible to send
6101 Replace ID packet to the server and force the server to change
6102 the Channel ID to the one router has.
6104 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6105 client that the Channel ID has been changed by the router. The
6106 normal server sends this to the client. Client must start using
6107 the new Channel ID as the channel's ID.
6109 Implemented handling of this new type into lib/silcclient/client.c
6110 into the function silc_client_notify_by_server.
6112 * Added new function silc_idlist_replace_channel_id into the files
6113 silcd/idlist.[ch] to replace the Channel ID.
6115 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Call silc_server_command_identify_check always when processing
6118 the IDENTIFY command in silcd/command.c
6120 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6123 send keepalive packets. The packet can be sent by clients,
6124 servers and routers.
6126 Added function silc_socket_set_heartbeat into the file
6127 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6128 If not set, the heartbeat is not performed. The actual
6129 heartbeat is implemented in the low level socket connection
6130 library. However, application is responsible of actually
6133 Added silc_server_send_heartbeat to send the actual heartbeat
6134 packet into silcd/packet_send.[ch]. Server now performs
6135 keepalive with all connections.
6137 * Added silc_task_get_first function into lib/silcutil/silctask.c
6138 to return the timeout task with shortest timeout. There was a bug
6139 in task unregistration that caused problems. TODO has been
6140 updated to include that task system must be rewritten.
6142 * The client library will now resolve the client information when
6143 receiving JOIN notify from server for client that we know but
6144 have incomplete information.
6146 * Rewrote parts of silc_server_remove_from_channels and
6147 silc_server_remove_from_one_channel as they did not remove the
6148 channel in some circumstances even though they should've.
6150 * Encryption problem encountered in server:
6152 The LEAVE command used to send the Channel Key packet to the
6153 router immediately after generating it. However, the code
6154 had earlier sent Remove Channel user packet but not immediately,
6155 ie. it was put to queue. The order of packets in the router
6156 was that Channel Key packet was first and Remove Channel User
6157 packet was second, even though they were encrypted in the
6158 reverse order. For this reason, MAC check failed. Now, this
6159 is fixed by not sending the Channel Key packet immediately but
6160 putting it to queue. However, this is more fundamental problem:
6161 packets that are in queue should actually not be encrypted
6162 because packets that are sent immediately gets encrypted
6163 actually with wrong IV (and thus MAC check fails). So, packets
6164 that are in queue should be encrypted when they are sent to
6165 the wire and not when they put to the queue.
6167 However, the problem is that the current system has not been
6168 designed to work that way. Instead, the packet is encrypted
6169 as soon as possible and left to the queue. The queue is then
6170 just purged into wire. There won't be any fixes for this
6171 any time soon. So, the current semantic for packet sending
6174 o If you send packet to remote host and do not force the send
6175 (the packet will be in queue) then all subsequent packets to the
6176 same remote host must also be put to the queue. Only after the
6177 queue has been purged is it safe again to force the packet
6180 o If you send all packets immediately then it safe to send
6181 any of subsequent packets through the queue, however, after
6182 the first packet is put to queue then any subsequent packets
6183 must also be put to the queue.
6185 Follow these rules and everything works fine.
6187 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Added new function silc_server_remove_clients_by_server to
6190 remove all client entries from ID list when the server connection
6191 is lost. In this case it is also important to invalidate all
6192 client entires as they hold the invalid server entry. This
6193 fixes fatal bug when server has lost connection and will reconnect
6196 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Made some sanity checks to silc_server_daemonise like to check
6199 whether the requested user and group actually exists.
6201 * Added sanity check to SKE's silc_ske_responder_finish to check
6202 that the public and private key actually is valid.
6204 * Invalidate the client's nickname when receiving Replace ID
6205 packet and the Client ID is being replaced. This means that the
6206 server will query the nickname if someone needs it (client)
6209 * Sort the ID Cache in client library when the ID Cache data
6210 has changed (needs sorting).
6212 * Do not allow for SILC client to create several connections to
6213 several servers. The client does not support windows right now
6214 and generating multiple connections causes weird behaviour.
6216 Irssi-silc client does support windows and can handle several
6217 connections without problems, see: www.irssi.org and SILC plugin.
6219 * Fixed some places where client was added to the IDList. The
6220 rule of thumb is following (in order to get everything right):
6221 If the client is directly connected local client then the
6222 `connection' argument must be set and `router' argument must be
6223 NULL to silc_idlist_add_client function. If the client is not
6224 directly connected client then the `router' argument must
6225 bet set and the `connection' argument must be NULL to the
6226 silc_idlist_add_client function.
6228 * The funtion silc_server_packet_send_local_channel actually did
6229 not check whether the client was locally connected or not. It
6230 does that now. Fixed a bug related to LEAVE command.
6232 * Fixed Remove Channel User payload parsing bug in server's
6233 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6235 * The server's silc_server_save_channel_key now checks also the
6236 global ID list for the channel as it might not be in the local
6237 list. Fixed a bug related to LEAVE command.
6239 * Is this the end of the [<unknown>] buglet that has been lurking
6240 around for a long time? A little for loop fix in server's
6241 silc_server_command_whois_parse that is used by both IDENTIFY
6242 and WHOIS command. At least, this was a clear bug and a cause
6243 of one type of [<unknown>] buglet.
6245 * WHOIS and IDENTIFY commands call the function
6246 silc_server_command_[whois/identify]_check function even if
6247 we are not router server.
6249 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Added --with-gmp configuration option. If set the GMP
6252 is always compiled in the SILC source tree. If not set then
6253 it is checked whether the system has the GMP3 installed. If
6254 it has then the GMP won't be compiled (the system's headers
6255 and library is used), if it doesn't have it then the GMP is
6256 compiled in the SILC source tree.
6258 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Changed RSA private exponent generation to what PKCS #1
6261 suggests. We try to find the smallest possible d by doing
6262 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6263 not security fix but optimization.
6265 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Added new config entry [Identity] to fork the server and run
6268 it as specific user and group. A patch from Bostik.
6270 * Imported Dotconf configuration library into lib/dotconf.
6271 This will be used to create the SILC configuration files later.
6272 It will appear in the distsribution after this commit.
6274 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6276 * A big code auditing weekend happening. Auditing code for
6277 obvious mistakes, bugs and errors. Also, removing any code
6280 Removed files for being obsolete:
6282 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6283 inline in the file lib/silcutil/silcbuffer.h)
6285 o lib/silcutil/silcbufutil.c (the header has inline versions)
6287 Changed code to fix possible error conditions:
6289 o The buffer formatting routines now check that the destination
6290 buffer really has enough space to add the data. This applies for
6291 both buffer formatting and unformatting
6292 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6293 unformatting was changed to accomodate following rules:
6294 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6295 sent to the function while XXX_*STRING will not allocate or copy
6296 the data into the buffer. Instead it sets the pointer from the
6297 buffer into the pointer sent as argument (XXX_*STRING used to
6298 require that the pointer must be allocated already). This change
6299 makes this whole thing a bit more consistent and more optimized
6300 (note that the data returned in the unformatting with XXX_*STRING
6301 must not be freed now). The routines return now -1 on error.
6303 o Tried to find all code that use buffer_format and buffer_unformat
6304 and added return value checking to prevent formatting and
6305 especially unformatting errors and possible subsequent fatal
6308 o Changed ske->x and ske->KEY to mallocated pointers in
6309 lib/silcske/silcske.h. Fixed possible data and memory leak.
6311 o Added return value checking to all *_parse* functions. Fixed
6312 many memory leaks as well.
6314 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6315 so that buffer overflows would not happen. All code now also
6316 checks the return value as it can fail.
6318 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6320 * Added reconnection support to server if the normal server looses
6321 its connection to the router (for example if router is rebooted).
6322 The server performs normal reconnection strategy implemented
6323 to the server. Affected file silcd/server.c.
6325 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Added new packet type SILC_PACKET_SET_MODE that is used to
6328 distribute the information about changed modes (for clients,
6329 channels and clients channel modes) to all routers in the
6330 network. Updated the protocol specification accordingly.
6332 Added functions into silcd/packet_send.c and
6333 silcd/packet_receive.c: silc_server_send_set_mode,
6334 silc_server_set_mode.
6336 Added new files silcmode.[ch] into lib/silccore that implements
6337 the encoding and decoding of Set Mode Payload. Added new type
6338 SilcSetModePayload. Moved the definitions of different modes
6339 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6341 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Oops, a little mistake in server's connection authentication
6344 protocol. The protocol is not ended with FAILURE but with
6345 SUCCESS if the authentication is Ok. :) Affected file is
6348 * Implemented NICK_CHANGE notify handling in server in the file
6349 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6350 the local clients on the channel. After the changing nickname
6351 in router environment snhould work and the [<unknown>] nickname
6352 should appear no more.
6354 The silc_server_replace_id function that receives the Replace ID
6355 payload now sends the NICK_CHANGE notify type also in the file
6356 silcd/packet_receive.c
6358 * Changed WHOIS and IDENTIFY command to support the maximum amount
6359 of arguments defined in protocol specs (3328 arguments). This
6360 fixed a bug that caused problems when there were more than three
6363 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Added extra parameter, command identifier, to the
6366 silc_client_send_command so that explicit command identifier
6369 Changed that ID list routines uses specific command identifier
6370 when sending WHOIS/IDENTIFY requests to the server so that they
6371 can be identified when the reply comes back.
6373 Affected files lib/silcclient/command.[ch],
6374 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6376 * Added `sender' argument to silc_server_packet_send_to_channel
6377 to indicaet the sender who originally sent the packet to us
6378 that we are now re-sending. Ignored if NULL. Affected file
6379 silcd/packet_send.[ch].
6381 * Added some server statistics support in silcd/server_internal.h
6382 SilcServerStatistics structure and around the server code. Also
6383 send some nice statistics information when client is connecting
6386 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Fixed channel ID decoding in server's JOIN command reply in
6389 silcd/command_reply.c
6391 * Fixed braodcasting of replace ID payload to not to send it if
6392 we are standalone server in silcd/packet_receive.c.
6394 * Fixed all channel message sending routines to not to send
6395 packets to clients that has router set, since they are routed
6396 separately in the same function earlier. Affects file
6397 silcd/packet_send.c and all channel packet sending functions.
6399 * In USERS reply, res_argv[i] are not allocated, the table
6400 is allocated. Thus changed that free the table, not its
6403 * In server's whois_check and identify_check if the client is
6404 locally connected do not send any WHOIS commands - they are not
6407 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Fixed some minor bugs in client when sending WHOIS command. The
6410 arguments was in wrong order.
6412 * Removed statis function add_to_channel from server in
6413 silcd/command.c that was previously used with the joining but
6416 * Tested USERS command in router environment successfully with two
6417 routers, two servers and two clients.
6419 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Reorganized the USERS command and command reply in client library
6422 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6423 When the command is given by user we register a pending command
6424 callback that will reprocess the command after the reply has been
6425 received from the server. When reprocessing the packet we then
6426 display the information. Thus, the USERS information is displayed
6427 now in the command callback instead of in the command reply
6428 callback. The processing of the command is same as previously
6429 when server has sent the command reply in the JOINing process.
6431 * Added to USERS command in silcd/command_reply.c to join the client,
6432 we didn't use to know about, to the channel after we've created
6433 a client entry for it. Also, for clienet we did know already still
6434 check whether it is on the channel or not and add it if not.
6436 * Removed silc_server_command_join_notify as the function and its
6439 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Changed the client's pending command handling to the same as the
6442 server's pending command handling. It is also now possible to
6443 execute command reply functions from other command reply
6444 function as the function callbacks for commands and command
6445 replies are one and same. The pending commands are not static
6446 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6447 in client connection context. Thus, pending commands are server
6448 connection specific as it is convenient.
6450 Changed the function silc_client_command_pending and
6451 silc_client_command_pending_del and added new function
6452 silc_client_command_pending_check. Removed the
6453 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6456 * Added cmd_ident, current command identifier, to the client
6457 connection context in lib/silcclient/client.h to keep track on
6458 command identifiers used in command sending. Client's command reply
6459 function handling now supports the mandatory command identifiers.
6461 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6462 funtions in client to fully support pending command callbacks.
6464 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6465 as one of the arguments to the application in the command reply
6468 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6469 before first releasing SILC but came back. Now it is removed again
6470 and should come back nomore. The FORWARDED flag was used only
6471 by the JOINing procedure by forwarding the command packet to router.
6472 Now, the JOINing procedure has been changed to more generic (due
6473 to various router environment issues) and FORWARDED is not needed
6474 anymore for anything. The protocol specification is yet to be
6477 Now, removed silc_server_packet_forward from server and the flag
6478 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6480 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Renamed NAMES command to USERS command. The NAMES was named that
6483 due to historical reasons. Now it is renamed. Also, rewrote
6484 parts of the USERS command. The nickname list is not sent anymore
6485 by the server. Only Client ID and mode lists are sent in the USERS
6486 command. Changed this also to the protocol specification.
6488 The client now resolves the names and stuff after it receives
6489 the USERS list from the server when joining to the channel.
6491 * WHOIS and IDENTIFY commands has been changed to support multiple
6492 Client ID's per command. One can now search for multiple users
6493 in the network by sending only one WHOIS or IDENTIFY command.
6494 Changed the code and the protocol specifications.
6496 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6497 uses silc_server_command_whois_parse to parse the request. */
6499 * If normal server, do not parse the WHOIS and IDENTIFY requests
6500 before sending it to the router. Saves some time.
6502 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Fixed JOIN command on client library. Wrong number of arguments
6505 used to crash the client.
6507 * Added silc_server_channel_has_global function to check whether
6508 channel has global users or not.
6510 * Added silc_server_channel_has_local function to check whether channel
6511 has locally connected clients on the channel.
6513 * The silc_server_remove_from_one_channel now checks whether the
6514 channel has global users or not after given client was removed from
6515 the channel. It also checks whether the channel has local clients
6516 on the channel anymore. If it does not have then the channel entry
6517 is removed as it is not needed anymore.
6519 * The silc_server_notify now checks on JOIN notify whether the joining
6520 client is one of locally connected or global. If it is global then
6521 the channel has now global users on the channel and that is marked
6522 to the channel entry. Also, it now saves the global client to
6523 global list who is joining and JOINs it to the channel. This is
6524 for normal server, that is.
6526 Changed silc_server_send_notify_on_channel,
6527 silc_server_packet_relay_to_channel and
6528 silc_server_packet_send_to_channel check if we are normal server
6529 and client has router set (ie. global client) do not send the
6530 message to that client, as it is already routed to our router.
6532 * Implemented LEAVE notify type handling in silc_server_notify
6535 * Tested LEAVE command in router environment successfully. Tested
6536 with two routers, two servers and two clients.
6540 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6542 * Implemented SIGNOFF notify type handling in silc_server_notify
6545 * silc_server_remove_id now removes the client entry from all channels
6546 it has joined and thusly sends SIGNOFF notify type.
6548 * Rewrote the NAMES list generation in server by removing two excess
6549 loops. The lists are created now inside one loop.
6551 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * silc_server_remove_channel_user checks now also global list
6554 for channel and client.
6556 * silc_server_new_channel_user checks now both local and global
6557 list for channel and client. Fixed a bug in client id decoding.
6558 Used to decode wrong buffer.
6560 * silc_server_channel_message checks now both local and global
6561 list for channel entry.
6563 * Tested channel joining (hence JOIN) in router environment
6564 successfully. Tested with two routers, two servers and two
6567 * Tested channel message sending in router environment successfully.
6569 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Added silc_server_save_channel_key into server.[ch] to save the
6572 received channel key in Channel Key payload processing. It is
6573 also used in JOIN command reply handling.
6575 Equivalent function silc_client_save_channel_key added into
6576 client.[ch] into client library.
6578 * Changed JOIN command reply to send information whether the channel
6579 was created or not (is existing already) and the channel key
6580 payload. Changed protocol specs accordingly.
6582 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6583 the request was sent by ID and not by nickname. Crashed on
6586 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6589 now correctly save the received data.
6591 * silc_server_free_sock_user_data now notifies routers in the
6592 network about entities leaving the network.
6594 At the same time implemented functions silc_server_remove_id
6595 and silc_server_send_remove_id to receive and send REMOVE_ID
6596 packets. The packet is used to notify routers in the network
6597 about leaving entities. The ID removed will become invalid in
6600 * Added function silc_idlist_del_server into server. Removes and
6601 free's server entry from ID list.
6603 * silc_server_private_message function now checks, if we are router,
6604 that the destination ID really is valid ID, naturally.
6606 * In router when NEW_ID packet is received (for new client) the
6607 hash of the Client ID is saved in the ID Cache but the
6608 client->nickname is set to NULL, instead of putting the hash
6611 IDENTIFY command now also checks that client->nickname must be
6612 valid. If it is not if will request the data from the server who
6613 owns the client. Added new function
6614 silc_server_command_identify_check.
6616 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6617 to set the command to already allocated Command Payload.
6619 * Tested private message sending in router environment with two
6620 routers, two servers and two clients. Fixed minor bugs and now
6623 * Fixed segfault from client's NAMES command. Used to crash if
6626 * Forwarded packets must not be routed even if it is not destined
6627 to the receiver. Changed server code comply with this.
6629 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Added `require_reverse_mapping' boolean value to ServerParams
6632 structure. If TRUE (not default) the server will require that
6633 the connecting host has fully qualified domain name.
6635 If the reverse mapping is not required and hostname could not be
6636 found the IP address is used as hostname.
6638 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Implemented version string checking to both client and server.
6641 The check is incomplete currently due to the abnormal version
6642 strings used in development version of SILC.
6644 * Changed all command functions in server to use the new
6647 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Changed char *data to unsigned char *data in ID Cache system to
6650 support binary data as ID Cache data. Changed code to support
6651 binary data in lib/silccore/idcache.c.
6653 * Renamed silc_server_packet_relay_command_reply to
6654 silc_server_command_reply as it is normal packet receiving
6655 function. Rewrote the function to accept command replys for
6656 servers and not only for clients.
6658 * Mark remote router always as registered server if we are connecting
6659 to it. Otherwise, commands sent by the router to us are ignored.
6661 * All ID List find routines now returns the ID Cache Entry pointer
6662 as well if requested.
6664 * WHOIS command works now in router environment, tested with two
6665 routers, two servers and two clients.
6667 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6668 in router environment (as it is almost equivalent to WHOIS) but
6669 hasn't been tested thoroughly. Added new functions:
6671 silc_server_command_identify_parse
6672 silc_server_command_identify_send_reply
6673 silc_server_command_identify_from_client
6674 silc_server_command_identify_from_server
6676 * Disabled route cache adding because adding two different ID's with
6677 same IP replaces the old cache entry thus giving wrong route.
6678 The entry->router->connection is always the fastest route anyway
6679 so route cache may not be needed. Of course, new routes maybe
6680 established after receiving the ID when the entry->router->connection
6681 might not be anymore the most optimal.
6683 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Add route cache for received ID for fast routing.
6687 * Added silc_server_packet_route to route received packet on router
6688 that is not destined to us.
6690 * Renamed silc_server_get_route to silc_server_route_get.
6692 * Added id_string and id_string_len fields into SilcServer to
6693 include encoded ServerID for fast comparing without excess
6694 encoding of the ID's.
6696 * Cleaned up WHOIS command on server side. Added following static
6699 silc_server_command_whois_parse
6700 silc_server_command_whois_check
6701 silc_server_command_whois_send_reply
6702 silc_server_command_whois_from_client
6703 silc_server_command_whois_from_server
6705 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6706 arguments in command replies. All command functions should be
6707 updated to use this macro.
6709 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Minor typo fixes on command reply handling on server.
6713 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Added silc_server_command_add_to_channel internal routine to add
6716 the client to the channel after router has created the channel and
6717 sent command reply to the server.
6719 * Added generic silc_server_send_command to send any command from
6722 * Use static buffer with ID rendering instead of duplicating data.
6724 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Fixed a channel user mode bug when joining to a channel server gave
6727 everybody channel founder rights, oops.
6729 * We mark ourselves as the router of the incoming server connection
6730 if we are router ourselves. This way we can check in some packet
6731 sending functions whether it is locally connected server. For
6732 incoming router connections we put NULL.
6734 * For router sending packets locally means now always sending the
6735 packet cell wide; to local clients and local servers. For normal
6736 server sending packet locally means sending it to only local
6739 * Fixed the JOIN command to really work in router environment. If the
6740 channel is created it is always created by the router. Router is
6741 also responsible of making the initial joining to the channel,
6742 sending JOIN notify to the sending server and distributing
6743 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6744 does not exist server doesn't do anything else but forward the
6745 command to the router which performs everything.
6747 * Added silc_server_send_channel_key function to send the Channel Key
6750 * Added silc_server_create_channel_key to create new channel key. The
6751 channel key is now re-generated everytime someone joins or leaves
6752 a channel, as protocol dictates. Note: channel->key_len is the
6755 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6758 packet_receive.[ch] to separate packet sending and receiving
6759 routines. The server.[ch] now includes everything else including
6760 actual packet processing (writing and reading data) and other
6763 Renamed silc_server_private_message_send_internal to
6764 silc_server_send_private_message. The routine is still though
6765 used only to relay private messages as server does not send
6766 private messages itself.
6768 Renamed silc_server_new_channel to silc_server_create_new_channel
6769 and added new function sicl_server_new_channel that handles the
6770 incoming New Channel packet. Added also new sending function
6771 silc_server_send_new_channel to send New Channel Payload.
6773 * Added new function silc_server_notify to process incoming notify
6774 packet to the server/router. Server may then relay the notify
6775 to clients if needed.
6777 * Added new function silc_server_new_channel_user to process incoming
6778 New Channel User packet. Router will redistribute the packet and
6779 send JOIN notify to its local clients and locally connected servers
6780 if needed. Normal server will send JOIN notify to its local client
6781 on same channel when received this packet. Added also corresponding
6782 sending function silc_server_send_new_channel_user to sent the
6785 * Added boolean route argument to send_notif_to_channel and
6786 packet_send_to_channel functions to attempt to route the packet
6787 if it is TRUE and send only locally if it is FALSE.
6789 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * silc_server_replace_id now broadcasts the received replace ID
6792 packet if it is not broadcast packet already. The router must
6793 broadcast to inform other routers about changed ID.
6795 * Added backpointer to server's router into SilcServer context in
6796 silcd/server_internal.h.
6798 * Fixed silc_server_packet_broadcast to send correct broadcast
6801 * The channel key is now distributed to the local client as soon
6802 as it is received from the router (in router environment) so that
6803 no other packet may be sent for the channel until client has
6806 * silc_server_remove_channel_user now broadcasts the received
6807 Remove Channel User packet if it is not broadcast packet already.
6808 The router must broadcast to inform other routers about removed
6811 * Added users field into SilcPacketContext that is a reference count
6812 of the context. One can increase the reference count by calling
6813 silc_packet_context_dup which is now changed to just increase the
6814 reference count instead of duplicating the data. The reference
6815 count is decresed by calling silc_packet_context_free that will
6816 free the data after the reference count hits zero.
6818 For now on the packet context and everything allocated into it
6819 (including the raw packet from network) must be freed by calling
6820 the new silc_packet_context_free function. Added also new function
6821 silc_packet_context_alloc that must be used now to allocate the
6822 context. This also means that if a routine is asynchronous from
6823 silc_[client/server]_packet_parse_type the packet context must
6824 be duplicated by calling silc_packet_context_dup. Otherwise it
6825 gets free'd after silc_[client/server]_packet_parse_type returns.
6826 Also, one must remember that if packet is duplicated then its
6827 reference count must be decresed by calling the free function as
6828 many times as it was duplicated.
6830 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6831 from both client and server.
6833 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Made joining to a channel working in router environment.
6837 * Cleaned up JOIN command on server side and create function
6838 silc_server_command_join_channel internal routine to make the
6841 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Changed silc_command_pending list to SilcDList. Also, added
6844 `ident' field to SilcServerCommandPending structure to identify
6845 the reply and to call correct callback.
6847 Added silc_server_command_pending_check function to replace the
6848 corresnponding macro. The silc_command_pending list is not
6851 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6852 to set identifier to previously allocated Command Payload. It
6853 is used to set identifier for command when resending Command
6856 * Added silc_command_payload_encode_payload to encode Command
6857 Payload buffer from SilcCommandPayload structure.
6859 * Added silc_argument_payload_encode_payload to encode Argument
6860 payload buffer from SilcArgumentPayload structure.
6862 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Changed WHOIS command to support router connection on server side.
6865 The whois request is always sent to router unless the server is
6866 standalone server. After server has received the reply from the
6867 router will it send the reply to the client.
6869 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6870 broadcast received broadcast packet. The function is used only
6871 by router. The broadcast packet is always sent to the router's
6874 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6875 render given ID to printable string, for log files for example.
6877 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Made basic router to router connections working. At least they
6880 can now connect to each other but nothing really works the way
6881 they are supposed - yet.
6883 * Added new initiator token to RouterConnection configuration
6884 file in silcd/serverconfig.[ch]. It is used to tell whether we
6885 are the initiator to the remote router or whether we'll expect
6886 the other end to connect.
6888 * Moved registering of listener task to silc_server_init, hence
6889 the server starts listenning as soon as it is run, even if it
6890 does not have connections to other routers. Let's see how well
6893 * Changed default connection retry timeouts for more suitable in
6896 * Removed cipher and such arguments from silc_idlist_add_client
6897 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6898 Added new function silc_idlist_add_data to add the keys and stuff
6901 * Added SilcIDListData structure and added it to SilcClientEntry
6902 and SilcServerEntry as their first field in the structure. This
6903 way we can explicitly cast the ID entries to the SilcIDListData
6904 structure and get common data for the entries. In past, we had
6905 to first check what type of connection it is and then cast it to
6906 correct ID entry type. Now, we can directly cast the opaque
6907 pointer to the SilcIDListData (no matter what ID entry it actually
6908 is) and get the data needed.
6910 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6913 in some circumstances even if threre were timeout tasks, though not
6914 IO tasks, but tasks anyway. Now fixed.
6916 * Defined SilcServerConnection structure to hold connection specific
6917 stuff about directly connected servers and routers. The definition
6918 is currently in silcd/server_internal.h. I thought about having
6919 a bit more important role fro this struct but for now it is used
6920 only when connecting to other server (or router actually).
6922 * Added connecting retry support in server when connecting to
6923 router(s). The retry feature implement exponential backoff
6924 algorithm. Also, added SilcServerParams structure to hold default
6925 parameters for server. For now, it include these retry settings
6926 and are hard coded. After server is moded to be as Silc Server
6927 Library this structure will be more important.
6929 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Changed client librarys channel->clients table to SilcList and
6932 changed code accordingly.
6934 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Changed client's channel table to SilcList and changed code
6937 accordingly. Also changed SilcChannelClientEntry to include back-
6938 pointer to the channel so that client entry can use that structure
6939 as list as well and we have fast cross-reference to the channel.
6940 This change dramatically decreased the complexity of channel
6941 handling with client entry and vice versa (removed one extra
6942 loop when searching for channel entry from many functions).
6944 * Changed server->sim from table to SilcDList and changed code
6947 * NAMES command can now be used from user interface. It will show
6948 the user list on the channel, neatly.
6950 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6951 Code now saves realname of the user if it becomes available.
6953 * Renamed configure.in to configure.in.pre and made ./prepare
6954 script to automatically add correct version string to
6955 configure.in which it creates from configure.in.pre.
6957 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6959 * NAMES command reply now shows users mode with the nickname when
6962 * Moved silc_client_ch[u]mode[_char] functions from
6963 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6964 place sucks, they are utility functions and should be in some
6967 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6969 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6972 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Added TRQ (efficient deque and list library) into lib/trq. This is
6977 a very good list library that is currently used in the SILC. Defined
6978 SilcList API over the library because I didn't like the API very
6979 much. See lib/trq/silclist.h for the API and examples of how to
6980 use the API. Fixed various places in the code to use the new
6981 SilcList API. The SilcList is meant for lists that has a structure
6982 already defined as a list. It is not suitable to add just some
6983 context to the list (in TRQ, the context is the list actually).
6985 So, I defined SilcDList that can be used for the purpose where
6986 predefined list structure does not exit. This can be used as
6987 such list. Now some context just can be added to the SilcDList.
6988 Currently this list is not used in the SILC just yet, though there
6989 are a lot places where this can replace dynamically allocated
6990 tables and I will fix these places, later, to use SilcDList.
6991 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6992 and use TRQ internally).
6994 Also fixed some annoying warning messages that the original TRQ
6995 code generated. Also minor changes to TRQ's Makefile.in.
6997 * Added support for querying by Client ID to both WHOIS and
6998 IDENTIFY commands into server, as required by the protocol.
7000 * Removed method function pointers from SilcBuffer structure. They
7001 weren't used to anything and just increased the context size for
7002 no good reason. This change also made silc_buffer_alloc and
7003 silc_buffer_free functions inline functions.
7005 * Disabled command flooding detection support until it's fixed so
7006 that it accepts commands in but does not execute them more than once
7009 * Added silc_net_localhost(), to return local hostname, into
7010 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7011 that must be initialized before calling silc_client_init.
7013 * Added new function: silc_server_send_notify_on_channels to send
7014 notify messages to all channels client has joined. It is assured
7015 that the message is sent only once per client.
7017 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7018 lib/silcutil/silcutil.[ch] as silc_format function. The new
7019 function is generic and is used by server as well, not only by
7020 the logging routines.
7022 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7023 the provided version string was not acceptable. Added new function:
7024 silc_ske_check_version into lib/silcske/silcske.h. The function
7025 must be implemented by the application (client or server) and it
7026 does not reside in the SKE library. The function checks the version
7027 string remote end sent.
7029 * Added back pointers (to opaque context and to SilcSocketConnection)
7030 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7032 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7033 duplicate packet context structure.
7035 * Changed `notify' client operation to send same arguments as client
7036 receives from server except for ID's. ID's are mapped to correct
7037 ID entry and that is returned. Also, if channel entry is not sent
7038 by server but the notify is for channel the channel entry is sent
7039 to application (otherwise application doesn't know that it is for
7040 channel (library gets it from packet's Destination ID)).
7042 * Added silc_client_remove_from_channels into client library to
7043 remove a client from all channels it has joined to. Used when
7044 received SIGNOFF notify from server. Added also new function
7045 silc_client_replace_from_channels to replace old ID entry with
7046 new ID entry on all channels. Used when received NICK_CHANGE
7049 * Fixed ID Cache list handling in silc_idlist_get_client in
7050 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7051 to get (or query) client by ID.
7053 * Updated TODO list.
7055 * Added connection authentication status message defined by the
7056 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7057 support for these into the code in client and server side.
7059 * Added generic function silc_client_send_command to send any command
7060 with variable argument list. Application should use this function
7061 to send commands if the command functions provided by the library
7062 does not suite for the application's user interface needs.
7064 * Added new `failure' client operation. Application is notified about
7065 received failure packet if client is executing a protocol. In this
7066 case the protocol's execution has failed.
7068 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7069 is required by the protocol.
7071 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7072 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7075 * Added status flag to SilcSKE object to indicate realtime status
7076 of the SKE protocol.
7078 * Application receives now exactly same command reply arguments as
7079 the library receives from server. However, if ID is received the
7080 corresponding ID entry is returned to the application (eg. Client
7081 ID is mapped to correct SilcClientEntry entry and that is returned).
7082 Changed command_reply client operation due to this change.
7084 * Changed all ID's in commands and in command replys as ID Payloads.
7085 Change affected both client and server side codes.
7087 All ID's sent in SILC network (with execption of ID's in SILC
7088 Packet header) are sent in ID Payload to support variable length
7091 * Server now notifies nick changes and notifies all clients on
7092 the channels about the new nickname (about the new Client ID,
7095 * Implemented CMODE command to change channel modes. Supports all
7096 channel modes defined by the protocol specs except ban and invite
7097 lists. (Also, private channel key mode is supported but support for
7098 setting private channel key in client is missing, thus, this mode
7099 has no effect on client side (except that server requires that the
7100 client uses private channel key and normal channel traffic does not
7103 Also, invite mode works per se, but INVITE command does not work
7104 yet correctly, so you can set channel as invite only channel but
7105 inviting clients to the channel does not work (it is yet to be
7106 thought what's the best way to do it).
7108 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7109 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7110 Implemented CUMODE command to change user's mode on the channel.
7111 Supports all modes defined by the protocol specs.
7113 * Added NAMES command reply to return users modes on the channel.
7115 * Removed unnecessary and slow ciphers from lib/silccrypt.
7117 * Set SO_KEEPALIVE option to connection sockets by default.
7119 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7121 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7122 redefined the Notify Payload into protocol specs.
7124 * Added silc_id_payload_parse_id to get ID directly from raw
7127 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7130 accept searching by Client ID as well.
7132 * Added support for LEAVE and SIGNOFF notify types in client library.
7134 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7135 to parse ID Payload from raw data.
7137 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7139 * Added flags parameter into silc_ske_assemble_security_properties
7140 function in lib/silcske/silcske.[ch].
7142 * Changed notify client operation to fit better for notify messages
7143 sent by server. The notify payload received from server is now
7144 passed to the application (after parsing it to SilcNotifyPayload).
7145 It is application's responsibility to retrieve the arguments
7146 from the payload and show the message the way it wants. The message
7147 sent by server is implementation specific.
7149 * Changed public keys to comply with the protocol specification.
7150 Old public keys are not supported anymore and are not compatible.
7152 * Removed nickname from Channel Payload as the latest draft removed
7153 it. The client must resolve the nickname from the NAMES command
7154 reply received when it joined the channel.
7156 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7158 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Fixed some errors in protocol specification drafts.
7162 * Created lib/silccore/silcnotify.c to implement Notify Payload
7163 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7164 generic payloads described by protocol specifications. The file
7165 includes implementations for ID Payload and Argument Payload.
7167 * Changed Command Payload implementation to use the new Argument
7168 Payload. Changed command_xxxx_payload to command_payload_xxxx
7169 to comply with SILC coding conventions.
7171 * Added suppport for Argument Payload handling in Notify Payload
7172 implementation as protocol requires it. Added the new support
7173 into server and client lib as well.
7175 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added support for multiple nicknames on same channel. [n] is
7178 added locally to the nickname if there are more than one same
7179 nicknames on the channel.
7181 * Server now sends all nicknames that matched WHOIS request.
7182 Client also shows the list received from server.
7184 * Added TOPIC command to client side. User can now set and show
7185 current topic on channel.
7187 * Added MOTD command to client and server. Also, server sends the
7188 motd when client connects to the server.
7190 * Changed version strings to comply ISO 8601.
7192 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Fixed protocol error handling in client library. It should now
7195 cope even if the SKE fails for some reason.
7197 * Made new protocol specification drafts for submitting to IETF.
7199 * Implemented TOPIC command to server in silcd/command.c.
7201 * Added two new notify types into lib/silccore/silcnotify.h:
7202 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7203 notify nickname change and topic setting/change on a channel.
7205 * API change of command_reply operation in client library. The
7206 application gets now the status type received from server as well.
7208 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7212 * Cras fixed and optimized the packet handling even further and
7213 it should work now. Minor change to the prototype of function
7214 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7216 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Added new function into lib/silcutil/silcschedule.[ch]:
7219 silc_schedule_with_fd to select() a specified fd. The function
7220 returns after timeout expires or data arrives or goes. The
7221 function is used by packet routines to wait that all data is
7222 received from network.
7224 * Fixed data reading from network in lib/silccore/silcpacket.c.
7225 The code now assures that all data is read from the fd and then
7226 continues packet processing. This was a bug fix since the code
7227 used to drop some data in some circumstances.
7229 * Added new function into lib/silcclient/client.[ch]:
7230 silc_client_start_key_exchange to start key exchange after
7231 connection has been established to server. The code internally
7232 now uses this funtion but its main purpose was to provide it
7233 for applications that perform their own connecting. After
7234 application has created a connection it merely calls this
7235 function to start the key exchange between client and server.
7236 The library takes care of everything else after that.
7238 Updated also lib/silcclient/README to explain the usage of
7241 * Do not send to application information that connection has
7242 been established. Application gets notified it by connect
7245 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7247 * Applied cras's patch to add silc_schedule_one function. The
7248 function runs scheduler once and returns.
7250 * Fixed the scheduler after cras messed it up. The timeout
7251 handling works now as it's supposed to work.
7253 * Added into lib/silccore/ silcnotify.h to include notify
7254 message types support. Changed silc_server_send_notify*
7255 functions, in server.[ch], to support those new notify types.
7256 Added the support for the notify types into client library,
7257 as well. Added new notify client operation into ops.h in
7260 * Changed silc_server_packet_send_to_channel to send normal
7261 packets instead of just channel message packets. The function
7262 is now used to send the notify packets to channels. It is not
7263 used to send channel message packets anymore, as server never
7266 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7267 va_arg()s as it seems to require it nowadays. I guess, if SILC
7268 is compiled with older va_arg() the new code should work anyway.
7270 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Splitted core library. Core library (lib/silccore) includes
7273 now only SILC protocol specific core (and common) components.
7274 Created new utility library (lib/silcutil) that includes more
7275 generic purpose stuff. The stuff for util library was taken
7276 from the old core library. This was minor and easy split.
7278 * Created SILC Client Library (lib/silcclient) that includes
7279 implementation of the SILC client without user interface. This
7280 was major move from silc/ directory. The code has been changed
7281 so that it is transparent towards the user interface. The
7282 silc/ directory includes now the same user interface as before
7283 and it uses the new client library. Read lib/silcclient/README.
7284 Basicly, the client library performs everything else related
7285 to SILC except user interface handling. Also, configuration
7286 files are considered to be part of user interface and library
7287 does not handle them.
7289 This change also changed a lot of structures, function naming etc.
7290 Most important change was that SilcClientWindow object was
7291 renamed to SilcClientConnection in the client library. Created
7292 also new file lib/silcclient/ops.h. Also added new files
7293 silc/local_command.[ch] and silc/client_ops.[ch].
7295 All these changes were made to make it easier for user interface
7296 designers to create what ever user interface for the SILC client
7299 It is also expected that the server will be moved to lib
7300 directory as well and SILC Server Library will be created;
7301 sometimes in the future.
7303 * Removed Local commands from lib/silccore/silccommand.h as
7304 they are application specific and new client library does not
7305 handle any of those anymore.
7307 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7308 old client implementation in silc/.
7310 * Added support for callback functions in SILC_LOG_* macros.
7311 Application can now set its own callbacks that will be called
7312 instead of using the default functions that will always print
7313 the debug messages to stderr (or stdout). Also, debugging can
7314 now be disabled by setting silc_debug to FALSE and re-enabled by
7315 setting it to TRUE. Note, that logging will still work even
7316 if debugging is disabled.
7318 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7319 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7320 silc_log_reset_debug_callbacks.
7322 * To enable debugging in silc client one must give now -d
7323 option on command line.
7325 * Changed silc_schedule_init to automatically allocate task queues
7326 if they are not allocated before calling it.
7328 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * Added GMP 3.1 into math library.
7332 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7335 a channel in SILC network. The packet is used by servers and
7336 routers to notify other routers that user has left a channel.
7337 This little feature was missing until now. Added the feature
7338 to protocol specification as well.
7340 Added functions: silc_server_send_remove_channel_user and
7341 silc_server_remove_channel_user into server.[ch].
7343 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7344 lib/silccore/silcpacket.h. However, they are not implemented
7347 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Fixed joining to a channel and sending channel messages
7350 between server and router. The channel message sending should
7351 now work inside a cell.
7353 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7355 * Fixed the private message sending between server and router.
7356 The private message sending should now work inside a cell.
7358 * Added silc_server_replace_id into server.[ch] to replace
7359 existing ID in the SILC network.
7361 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7362 and silc_idlist_replace_server_id into idlist.[ch] in server.
7364 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * Fixed the server to server connections. Server can again now
7367 connect to router. Router to router connections probably does
7370 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Added dynamic protocol registering support. Now protocols can
7373 registered and unregistered on the fly. Patch by cras.
7375 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Added lib/contrib directory to hold routines that some platforms
7378 don't have but are needed by SILC.
7380 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7381 into lin/contrib to provide getopt() and getopt_long() for
7382 those who don't have it.
7384 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Added AWAY command to client. When away message is set and
7387 client receives a private message packet the client automatically
7388 replies to the sender with the away message.
7390 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7391 bug seemed to be the cause of recent problems when compiling
7394 * Added version detection support to SKE protocol specification
7395 and added the new changes to the SKE implementation as well.
7396 There were other minor changes in the SKE protocol as well.
7398 Many changes in lib/silcske/silcske.[ch] and in
7399 lib/silcske/payload.[ch].
7401 * Added ^U functionality, clear input line. Patch from cras.
7403 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Mainly small bugfixes on core library. Fixed some debugging
7406 logging and buffer overflow in silclog.c.
7408 * Updated config.sub and config.guess on the distribution tree.
7410 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Added command lagging support in server. Client may execute
7413 commands now only once in two seconds.
7415 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7417 * Optimized packet reception. MAC computation and checking is now
7418 also more optimized. A lot previously duplicated code is now
7419 used as generic by both client and server.
7421 * Fixed key pair generation in clientutil.c
7423 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Added into lib/silccore/silcbufutil.[ch] new function;
7426 silc_buffer_realloc.
7428 * Moved generic packet sending/encryption functions to
7429 lib/silccore/silcpacket.[ch] from client and server. Some
7430 rewriting of the functions.
7432 * Moved all generic packet reception/decryption functions to
7433 lib/silccore/silcpacket.[ch] from client and server. The
7434 packet processing is now much cleaner in both client and server.
7435 These were major changes in both client and server.
7437 * Created many common functions in server to do packet sending.
7438 Previously code were duplicated a lot, this has been removed
7441 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Rewrote major parts of the ID cache system. Don't know
7444 whether it is better now or not but at least the API is more
7447 * Major rewrite on ID cache stuff on client because of the ID
7448 cache API changes. Added idlist.c to client.
7450 * Also major rewrite on ID cache stuff on server as well.
7451 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7452 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7453 in hand, instead they are all put into the ID cache system now.
7454 All server_idlist_* routines uses ID cache now instead of
7455 traversing its own lists (those lists does not exist anymore).
7456 SilcIDList though still exists. Also, SilcXXXEntry's are
7459 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7461 * Finally made the SKE implementation compliant to the protocol
7462 specification. All mp integers are now binary encoded as
7463 opposed being HEX encoded.
7465 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7468 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7469 functions: silc_[encode/decode]_pem. Also added function
7470 silc_encode_pem_file to PEM encode with newlines ('\n') for
7473 * SILC public keys are now encoded either PEM or binary. Same
7474 option is for private keys as well. By default private keys
7475 are binary encoded and public keys PEM encoded. Silly HEX
7476 encoding were removed.
7478 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7479 function to create fingerprints.
7481 * Fixed a bug in SHA1; does not change the original data anymore.
7483 * Partly implemented INFO command on client and server side.
7484 Fixed CLEAR command. Changes to SERVER command; show current
7485 server(s) when giving command without arguments. Added
7486 VERSION command to client.
7488 * Added check to server that unregistered connections cannot
7489 execute commands (unless it is specificly allowed).
7491 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7493 * Fixed screen refresh.
7495 * Fixed channel joining bug from client. On some circumstances
7496 client tried to join to a channel it had already joined.
7498 * Added public key verification process into client's protocol.c.
7499 The client now verifies the public key from user and saves
7500 it into ~./silc/serverkeys/ directory.
7502 Added into: clientutil.[ch]: silc_client_verify_server_key.
7504 * Changed SKE protocol's silc_ske_initiator_finish function
7505 to accept callback function that verifies the received public
7506 key. Removed old silc_ske_verify_public_key function.
7508 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7511 silc_pkcs_private_key[_data]_set.
7513 * Made the password and public authentication more cleaner in
7514 server's protocol.c.
7516 * Removed historic and obsolete protocol `channel_auth' from
7517 both client and server.
7519 * Removed wrong way of sending command status messages from
7520 server to client in server's command.c. The old way violated
7521 protocol specification.
7523 Changes to silccore/silccommand.[ch]: removed
7524 silc_command_encode_status_payload -> not needed anymore,
7525 changed silc_command_encode_payload_va to accept extra
7526 argument on variable argument list. The argument type must
7527 now be provided to the function. Also, added new function:
7528 silc_command_encode_reply_payload_va which is same as
7529 normal command_encode_payload_va except command status type
7530 is provided as extra argument.
7532 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Added ~./silc directory handling. The directory includes the
7535 public and private keys for the client.
7537 Added silc_client_check_silc_dir, silc_client_create_identifier
7538 and silc_client_load_keys.
7540 * Implemented SILC protocol compliant public key. Added public
7541 and private key saving to and loading from files.
7543 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7544 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7545 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7546 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

7554 * Added silc_server_get_route (route.[ch]) to get connection
7555 data for the fastest route for given ID.
7557 * Implemented INVITE command on client and server. The command
7558 were re-defined in the SILC Protocol Specification and the
7559 implementation now complies with the specification.
7561 * Implemented PING command on client and server.
7563 * Implemented NAMES command on client and server. The server side
7564 supports currently only normal server not router server yet.

7572 again. This change was made to the protocol as well. Server
7573 should not violate the protocol specification anymore.

7577 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
