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

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

612 is changed and +k mode is set in the channel. Affected file
613 irssi/src/silc/core/silc-channels.c.
615 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
616 SILC_LOG_WARNING to give out Warning and not Error. Affected
617 file lib/silcutil/silclog.c.
619 * Fixed the channel message payload decryption in the function
620 silc_channel_message_payload_decrypt to not modify the original
621 buffer before it is verified that the message decrypted
622 correctly. Otherwise, next time it is called with correct
623 channel key it won't encrypt since the payload is corrupted.
624 Affected file lib/silccore/silcchannel.c.
626 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Do not constantly resize the window. A fix patch by cras.
629 Affected file irssi/src/fe-text/screen.c.
631 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
634 Affected file lib/silcutil/silcnet.c.
636 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
638 * Fixed a bug in hash table internal routine for traversing
639 the table with foreach callback. The current entry may
640 become invalid in the callback but it was referenced after
641 the callback returned.
643 Do not allow auto rehashing of hash table during the
644 silc_hash_table_foreach operation, for same reasons as it is
645 not allowed for SilcHashTableList. Affected files are
646 lib/silcutil/silchashtable.[ch].
648 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Defined DLLAPI into silcincludes.h and silcwin32.h for
651 Win32 DLL. extern's in header files are now declared with
654 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Fixed private message handling. It used some old code that
657 caused the client to crash. Affecte file is
658 lib/silcclient/client_prvmsg.c.
660 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
662 * Added function silc_client_add_channel,
663 silc_client_replace_channel_id, and removed functions
664 silc_client_new_channel_id and silc_idlist_get_channel_by_id
667 * Added cross reference of the joined channels to the
668 SilcClientEntry, and changed the SilcChannelEntry's
669 users list to SilcHashTable. The affected files are
670 lib/silcclient/idlist.[ch].
672 * Fixed a bug in hash table tarversing. While the hash table
673 is traversed with SilcHashTableList the table must not be
674 rehashed. It is now guaranteed that auto rehashable tables
675 are not rehashed while tarversing the list. Also defined that
676 silc_hash_table_rehash must not be called while tarversing
677 the table. Added function silc_hash_table_list_reset that must
678 be called after the tarversing is over. The affected files are
679 lib/silcutil/silchashtable.[ch].
681 * Changed all hash table traversing to call the new
682 silc_hash_table_list_reset in server and in client library.
684 * Added function silc_client_on_channel to return the
685 SilcChannelUser entry if the specified client entry is joined
686 on the specified channel. This is exported to application as
687 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
689 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Fixed founder regaining problem with JOIN command on normal
692 server. The notify for mode change must be sent always and
693 not only if !cmd->pending. Affected file silcd/command.c.
695 * Fixed the WHOWAS command's reply sending to support the
696 lists correctly. Affected file silcd/command.c.
698 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * When sending JOIN command to router for processing the
701 sender's old command identifier was not saved back to the
702 sender's command context, fixed now. The affected file is
705 * Create the key in JOIN command of the router did not return
706 the channel key, added check for this. Affected file is
709 * Fixed a channel ID update bug in JOIN command reply. Do
710 not directly upgrade the ID but call the function
711 silc_idlist_replace_channel_id if the ID was changed.
712 Affected file silcd/command_reply.c.
714 * Fixed memory leaks from command calling if it would fail.
715 Affected file silcd/command.c.
717 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
719 * Applied patches from cras:
721 Memory leak fixes around libaries, irssi window resize fix,
722 new silclist.h and silcdlist.h, all extern inline changed to
725 * Removed dotconf from lib/dotconf, not needed anymore.
727 * Removed TRQ from lib/trq, not needed anymore.
729 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
730 with server connections. Later this will be configurable
731 in config file after new config file is done. Affected file
734 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
736 * Fixed a crash in server related to channel announcements.
737 Affected file silcd/server.c.
739 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Fixed memory leaks in silc_server_create_new_channel*
742 functions. Affected file silcd/server.c.
744 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
745 which ID was changed. This way the router will send the
746 user list for the channel again, and server won't be in
747 desync in some rare circumstances. Affected file is
748 silcd/packet_receive.c.
750 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
752 * Check for NULL socket pointer in the function
753 silc_server_packet_send_to_channel_real. Affected file
756 * Fixed the BAN notify handling to correctly remove ban
757 list. Affected file silcd/packet_receive.c.
759 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
761 * Fixed some header addition to Toolkit distribution in
762 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
764 * Added lib/silcclient/client_ops_example.h as an template
765 file for application programmers to quickly start using
766 the SilcClientOperation functions in their application.
767 Updated the lib/silcclient/README as well to tell about this
768 nice file made available.
770 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
772 * Call silc_server_remove_from_channels when removing client
773 entry when NO_SUCH_CLIENT_ID was received. Affected file
774 is silcd/command_reply.c.
776 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
778 * Added server & router operator statistics updating. Affected
779 file silcd/packet_receive.c and silcd/command.c.
781 * Fixed the SERVER_SIGNOFF notify handling on normal server
782 not to save the history information for clients. Same was
783 fixed earlier in remove_clients_by_server function, but not
784 here. Affected file silcd/packet_receive.c.
786 * Raised the default connection-retry count from 4 to 7 in
787 server. Affected file silcd/server.h.
789 * Cancel any possible reconnect timeouts when we start the
790 key exchange. Affected file silcd/server.c.
792 * Do not reconnect on connection failure when SCONNECT was
793 given. Affected files silcd/server.[ch].
795 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
799 * Fixed the NICK command to always give the unformatted
800 nickname to the one giving the NICK command. If unformatted
801 nickname is cached already it will be formatted and the
802 local entry will always get the unformatted nickname.
803 Affected file lib/silcclient/idlist.c.
805 * Fixed some double frees from client library commands.
806 Affected file is lib/silcclient/command.c.
808 * Fixed CUMODE command in server to assure that no one can
809 change founder's mode than the founder itself, there was a
810 little bug. Affected file silcd/command.c.
812 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
814 * Removed the SilcClientCommandDestructor from the client
815 libary, it is not needed anymore. Affected files are
816 lib/silcclient/silcapi.h, command[_reply].[ch],
817 client_notify, idlist.c.
819 * Fixed GETKEY command to first resolve client, and then
820 resolve the server only if the client was not found, instead
821 of resolving both at the same time. Affected file is
822 lib/silcclient/command.c.
824 * Added silc_client_start_key_exchange_cb and lookup the
825 remote hostname and IP address before starting the key
826 exchange with server. The affected file is
827 lib/silcclient/client.c.
829 * The server's public key is now saved using the IP address
830 of the server and not the servername for the filename.
831 The hostname public key filename is checked as an fall back
832 method if the IP address based filename is not found.
834 Fixed the GETKEY command to save the fetched server key
837 Print the remote server's hostname now when new key is
838 received during connection process. Affected file is
839 irssi/src/silc/core/client_ops.c.
841 * Return always our own public key to the client if it asks
842 for it with GETKEY command. Affected file silcd/command.c.
844 * Removed the use_auto_addr variable from default config
845 file since it was in wrong section. Affected file is
848 * Fixed TOPIC_CHANGE notification to not route it when it
849 was sent using silc_server_send_notify_to_channel function.
850 Affected file silcd/command.c.
852 * Fixed silc_server_send_notify_kicked to send the kicker's
853 Client ID also, it was missing. Affected files are
854 silcd/command.c, silcd/packet_send.[ch].
856 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
858 * Do not save client history information in SERVER_SIGNOFF.
859 Fixes the bug in normal server that it does not detect
860 the client becoming valid after the server becomes back
861 online. Affected file silcd/server_util.c.
863 * Added `sock_error' field into the SilcSocketConnection
864 context. When error occurs during socket operation (read
865 or write) the error is saved. Added also new function
866 silc_socket_get_error to return human readable socket error
867 message. Affected files are lib/silcutil/silcsockconn.[ch],
868 lib/silcutil/unix/silcunixsockconn.c, and
869 lib/silcutil/win32/silcwin32sockconn.c.
871 * The server now prints the socket error message in the
872 signoff for client. Affected file silcd/server.c.
874 * Fixed the `created' channel information sending from router
875 to server in JOIN command. Checks now whether the channel
876 really was created or not and set it according that.
878 Fixed the JOIN command to use the client entry's current
879 ID during the joining procedure instead of the one it sent
880 in the command (it is checked though), since it can change
881 between the packet processing and command processing, and
882 would just case unnecessary pain in the client end. Affected
883 file silcd/command.c.
885 * Fixed a channel key payload sending to use correct channel
886 ID when the server was forced to change the channel's ID by
887 router. Router sent the key payload with the old Channel ID.
888 Affected file silcd/packet_receive.c.
890 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
892 * Call silc_server_save_channel_key only if the key payload
893 was provided in the JOIN command's command reply. Affected
894 file silcd/command_reply.c.
896 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
898 * Fixed silc_mp_sizeinbase to return the value correctly with
899 MPI. Affected file lib/silcmath/mp_mpi.c.
901 * Fixed the stop_server signal to correctly stop the scheduler
902 and gracefully stop the server when SIGTERM or SIGINT signals
903 are received. Affected file silcd/silcd.c.
905 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
907 * Simple handling of TERM and HUP signals. Also added some log
908 flushing call around. Affected file is
911 * Fixed small bugs in silclog.c. Now buffering output will take
912 effect after 10 seconds since startup: This will ensure that
913 no important startup messages are lost. Also output redirection
914 will preserve original format ([Date] [Type] message).
915 Affected file is lib/silcutil/silclog.c.
917 * Added two options to the config file, in the logging section:
918 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
919 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
921 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Do not print the warning about log files not being initialized
924 more than once to avoid excess logging. Affected file is
925 lib/silcutil/silclog.c.
927 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
928 the SIM copying in make install in Makefile.am.pre.
930 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
932 * Rewritten silclog APIs. Globally interesting changes follows:
933 silc_log_set_files() changed to silc_log_set_file().
934 silc_log_set_callbacks() changed to silc_log_set_callback().
935 ROBOdoc documented silclog header file.
936 SilcLogCb now returns bool to wether inihibit the default
937 handler or not (to keep the old behaviour return always TRUE).
938 The new APIs should also fix the problem of the
939 silcd_error.log file that was written in the current directory.
942 Log files streams will remain opened after silc_log_set_file()
943 call, means less CPU usage notably on high traffic servers.
944 File streams are now full buffered, and flushed to the disk
945 every 5 minutes, lesses HD activity and CPU usage.
946 Messages can be redirected, allowing admins to configure
947 one single logfile for all server messages.
948 the silc_log_quick global variable to activate fast-logging.
949 Affected files lib/silcutil/silclog.[ch]
951 * Changed some code to conform new silclog APIs. Affected
952 files are doc/example_silcd.conf.in, silcd/server.c
953 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
956 * Fixed a memory leak that could occur in some situations.
957 Affected file silcd/serverconfig.c.
959 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Added the silc_client_del_client to remove the client from
962 all channels as well. Affected file lib/silcclient/idlist.c.
964 * Fixed the client library to correctly remove the client
965 from all channels when the client entry is being destroyed.
966 Affected file lib/silcclient/client_notify.c, command.c.
968 * Added auto-nicking support to the client library. If the
969 applicatio now sets client->nickname it will be sent to the
970 server after connecting by the library. This way for example
971 SILCNICK (or IRCNICK) environment variables will have effect
972 and always change the nickname automatically to whatever
973 it is wanted. Affected file lib/silcclient/client.[ch].
975 * Renamed silc_server_command_bad_chars to the
976 silc_server_name_bad_chars and moved it to the
977 silcd/server_util.[ch]. Added also new function
978 silc_server_name_modify_bad to return nickname that
979 includes bad characters as new nickname without those
980 bad characters. This check and modify is now used in
981 silc_server_new_client when the username is initially set
982 as nickname, so it must be checked to be valid nickname.
983 Affected file silcd/packet_receive.c.
985 * The nickname length is now taken from the packet for real
986 and not trusted to strlen() since it clearly can return
987 wrong length for nickname including bad characters. This
988 also applies to channel names. Affected file silcd/command.c.
990 * Removed the lib/silcsilm/modules directory. Modules are now
991 compiled into the lib/silcsim. Fixed the copying of the
992 modules to follow symbolic links in Makefile.am.pre.
994 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
996 * Fixed silc_string_regexify list creation. Fixes bugs with
997 BAN and INVITE commands in server. The affected file is
998 lib/silcutil/unix/silcunixutil.c.
1000 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Removed the command destructor entirely from the server's
1003 command and command reply routines. It is not needed, and
1004 its usage was buggy and caused crashes. Affected files are
1005 silcd/command[_reply].[ch].
1007 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Cancel protocol and NULL sock->protocol if timeout
1010 occurred during protocol. Affected file silcd/server.c.
1012 * Cancel protocol timeouts always before calling the final
1013 callback, to assure that after final callback is called
1014 no other state will be called for the protocol anymore.
1015 Affected file silcd/protocol.c.
1017 * Print error log if incoming connection configuration could
1018 not be found. Affected file silcd/server.c.
1020 * Fixed JOIN command to correctly save the founder mode
1021 to the client on normal SILC server, when the channel
1022 was created by the router. Affected file silcd/command.c.
1024 * Fixed LIST command (hopefully) to send correct reply
1025 packets. Affected file silcd/command.c.
1027 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * The silc_packet_receive_process now returns FALSE if the
1030 read data was invalid packet, and TRUE if it was ok.
1032 The server now checks that if unauthenticated connection
1033 sends data and its processing fails the server will close
1034 the connection since it could be a malicious flooder.
1036 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1038 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Make sure the warning about error opening a log file is
1041 printed only once and not everytime it fails (produces
1042 too much useless log). Affected file lib/silcutil/silclog.c.
1044 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1046 * Made the silc_server_daemonise() function more readable.
1047 Affected file silcd/server.c.
1049 * Pid file is now optional, the user may comment it out from
1050 the config file. Removed define SILC_SERVER_PID_FILE, we
1051 don't need a default any longer. Affected file
1052 configure.in.pre, lib/Makefile.am.pre.
1054 * Make some use of the pid file. The server now dies at startup
1055 if it detects a valid pid file on his path. The server would
1056 die anyway in this circumstance, because of the bind() failure.
1057 Affected file silcd/silcd.c.
1059 * No longer compiling lib/dotconf.
1061 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * Fixed JOIN command parsing not to crash. Affected file
1064 lib/silcclient/command.c.
1066 * Fied the NICK_CHANGE notify to add the new client entry
1067 even it is resolved. This removes an <[unknown]> nick
1068 thingy bug in the client. Affected file is
1069 lib/silcclient/client_notify.c.
1071 * Do not try to allocate 0 bytes (efence does not like it)
1072 in lib/silccore/silccomand.c when encoding payload.
1074 * Do not take IRCNICK as nickname in Irssi SILC client since
1075 it is not possible to set nickname before hand connecting
1076 the server (TODO has an entry about adding auto-nicking
1079 * Changed the silc_server_command_pending to check whether
1080 there already exists an pending entry with the specified
1081 command, command identifier and pending callback. This is
1082 to fix IDENTIFY and WHOIS related crashes that may register
1083 multiple pending commands with same identifier. Affected
1084 file silcd/command.c.
1086 * Fixed the server to reconnect to the router even if it
1087 was already reconnecting and EOF was received. This to
1088 fix a possibility that the server wouldn't ever try to
1089 auto-reconnect to the router. Affected file silcd/server.c.
1091 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Fixed the server's password authentication to use the
1094 length of the locally saved password, and not the one
1095 sent in the packet. Affected file silcd/protocol.c.
1097 * Fixed same password authentication problem in the
1098 Authentication Payload handling routines in
1099 lib/silccore/silcauth.c.
1101 * Yet another password authentication problem fixed with
1102 channel password handling in silcd/command.c.
1104 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1106 * If first character of string in silc_parse_userfqdn is '@'
1107 then do not parse it. Affected file is
1108 lib/silcutil/silcutil.c.
1110 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Fixed minor bug in IDENTIFY command reply sending, which
1113 caused various weird problems during JOIN when it was
1114 resolving names for users. Affected file silcd/command.c.
1116 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Fixed the IDENTIFY command reply sending to chech better valid
1119 clients. It was possible to send incomplete list of replies.
1120 Affected file silcd/command.c.
1122 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1124 * Added silc_client_command[s]_[un]register functions now to
1125 dynamically register the commands in client library. Removed
1126 the static table of commands. This allows the client library
1127 to call commands without causing the application to know about
1128 what commands library has called.
1130 Removed the INFO command reply kludge to detect when the command
1131 was called by library. Now library use its own command reply
1132 function for INFO command.
1134 Added function silc_client_command_call to call a command.
1135 Application can use it to call command, not access the structure
1138 Now all commands that are sent by the client library (not
1139 explicitly sent by application) use own command reply functions.
1141 Affected files around lib/silcclient/ and in
1142 irssi/src/silc/core/.
1144 * Fixed the WHOIS command reply sending to chech better valid
1145 clients. It was possible to send incomplete list of replies.
1147 Fixed the WHOIS and IDENTIFY to send the request to router
1148 if normal server did not do it and did not find any results.
1150 Affected file silcd/command.c.
1152 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1154 * Moved the internal data from SilcClient context into its
1155 own file, not accesible to application. Affected files
1156 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1157 and other files in client library.
1159 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * Added doc/examples installation target in Makefile.am.pre.
1164 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1167 commands the found client entry will be removed from the
1168 cache, after notifying application about the error. Affected
1169 file lib/silcclient/command_reply.c.
1171 * Changed the /MSG to check for exact nickname user gave, and
1172 not let `nick' match `nick@host' if it is only one found. Now,
1173 user must type the exact nickname (like nick@host2) even if
1174 there are no more than one same nicks found. This is to avoid
1175 a possibility of sending nickname to wrong nickname since
1176 `nick' could match `nick@host'. Affected file is
1177 irssi/src/core/silc-servers.c.
1179 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1181 * Do not print "you are now server operator" or similar when
1182 giving /away command. Affected files are
1183 irssi/src/silc/core/client_ops.c, silc-servers.h.
1185 * Made the silc_server_command_pending_error_check to send
1186 the same command reply payload it received back to the
1187 original sender of the command. This way all arguments
1188 that was received by the server will be received by the
1189 client too. Affected file silcd/command.c.
1191 * Added the silc_idcache_add to return the created cache entry
1192 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1194 * Add global clients to expire if they are not on any channel.
1195 This is because normal server will never know if they signoff
1196 if they are not on any channel. The cache expiry will take
1197 case of these entries. This is done by normal servers only.
1198 The affected files are silcd/command_reply.c,
1199 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1201 * If server receives invalid ID notification for WHOIS or
1202 IDENTIFY and the ID exists in the lists, it is removed.
1203 Affected file silcd/command_reply.c.
1205 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1206 in client then client entry that it matches is searched and
1207 the nickname is printed on the screen for user. Affected
1208 file irssi/src/silc/core/client_ops.c.
1210 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Use cache entry expire time in the LIST command reply to
1213 purge old entries from the cache after the LIST command
1214 reply has been received. This way we don't have non-existent
1215 entries in the cache for too long. Affected file is
1216 silcd/command_reply.c.
1218 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1220 * If we are normal server, and we've not resolved client info
1221 in WHOIS or IDENTIFY from router, and it is global client,
1222 we'll check whether it is on some channel. If it is not
1223 then we cannot be sure about its validity and will resolve it
1224 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1225 file silcd/command.c.
1227 * Search channel by name (if possible) rather than by ID
1228 in IDENTIFY command's command reply. Affected file is
1229 silcd/command_reply.c.
1231 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1234 Updated specs and implemented it. Affected file silcd/command.c,
1235 silcd/packet_send.c and silcd/packet_receive.c.
1237 * Implemented the <founder auth> payload handling in the JOIN
1238 command. If provided all conditions for channel joining
1239 except requirement to provide correct passphrase can be
1240 overrided by the channel founder. Updated the protocol specs.
1241 Affected file silcd/command.c.
1243 Added support for founder auth in JOIN command in client
1244 library. Fixed the parsing of the JOIN command now to support
1245 all options as they should be. The affected file is
1246 lib/silcclient/command.c.
1248 * Optimized the WHOIS and IDENTIFY commands to send the request
1249 to router only if it includes nicknames or other names. If
1250 they include only IDs then check the local cache first before
1251 routing. Affected file is silcd/command.c.
1253 * Added channels topic announcements. Affected file is
1254 silcd/packet_receive.c and silcd/server.c.
1256 * Fixed the silc_server_send_notify_topic_set to really destine
1257 the packet to channel. Affected file silcd/packet_send.c.
1259 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1260 library. Affected file lib/silcclient/client_notify.c.
1262 * Added UMODE announcements. Affected file silcd/server.c.
1264 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Memory leak fixes in:
1268 lib/silcutil/silcsockconn.c
1269 lib/silcske/silcske.c
1270 lib/silcske/groups.c
1272 lib/silccrypt/silcpkcs.c
1273 lib/silccore/silccommand.c
1274 lib/silccore/silcidcache.c
1279 * ROBOdoc documented the lib/silcske/groups.h file and a
1280 bit changed the interface for better.
1282 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1284 * Update the client entry context in the ID cache after
1285 nick change. Affected file lib/silcclient/command.c.
1286 Fixes the CUMODE command when regaining founder privileges,
1287 and a little WHOIS problem.
1289 * Fixed silc_net_gethostbyname to correctly call the
1290 inet_ntop. Affected file lib/silcutil/silcnet.c.
1292 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1294 * Added IPv6 support checking to the configure.in.pre, added
1295 also --enable-ipv6 option to override the check. Affected
1296 file configure.in.pre.
1298 * The silc_thread_create now calls the start function
1299 directly if threads support is not compiled in. Removes
1300 ugly #ifdef's from generic code. Affected files are
1301 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1303 * Added silc_net_gethostby[name/addr]_async to asynchronously
1304 resolve. Affected files are lib/silcutil/silcnet.[ch].
1306 * Added support for rendering IPv6 based server, client and
1307 channel IDs. Affected file lib/silcutil/silcutil.c.
1309 * Added support for creating IPv6 based server IDs. Affected
1310 file is silcd/serverid.c.
1312 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1314 * Added silc_net_gethostby[addr/name] into the
1315 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1316 routines. Added silc_net_is_ip[4/6]. Affected file is
1317 lib/silcutil/unix/silcunixnet.c. All routines that take
1318 address as argument now supports both IPv4 and IPv6 addresses.
1320 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1322 * Fixed LIST command reply sending in server. Affected file
1325 * Server now sends the kicker's client ID in the KICK notify
1326 to the kicked client. Affected file silcd/command.c.
1328 * The client library now parses the kickers client ID and
1329 UI displays it. Affected files lib/silcclient/client_notify.c
1330 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1332 * Made all payload parsing function prototypes consistent.
1333 They all take now const unsigned char * and uint32 pair as
1334 the payload data instead of SilcBuffer. Changes all around
1335 the source tree. Other unsigned char* -> const unsigned char*
1336 changes around the tree as well.
1338 * Optimized SFTP client and server packet sending not to
1339 allocate new buffer for each packet but to recycle the
1340 first allocated buffer. Affected files are
1341 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1343 * Optimized the SFTP client to use SilcList instead of
1344 SilcDList for requests, because it is faster. Affected file
1345 is lib/silcsftp/sftp_client.c.
1347 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1348 into lib/silccore/silcid.[ch].
1350 Renamed silcpayload.[ch] into silcargument.[ch].
1352 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * If client entry is deleted with active key agreement
1355 session, abort the session.
1357 The silc_client_abort_key_agreement now calls the completion
1358 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1360 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1363 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * Don't use __restrict in older GCC's. Affected file is
1366 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1368 * silc_net_localhost now attempts to reverse lookup the
1369 IP/hostname. Affected file lib/silcutil/silcnet.c.
1371 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1372 command. It can be used to gain founder privileges at
1373 the same time when joining the channel.
1375 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1376 kicker's client ID as well. Updated protocol specs.
1378 Defined that the server must send SILC_COMMAND_IDENTIFY
1379 command reply with error status to client who sent
1380 private message with invalid client ID.
1382 Updated the protocol specification.
1384 * Added silc_server_send_command_reply to send any
1385 command reply. Affected file silcd/packet_send.[ch].
1387 * Added silc_id_payload_encode_data to encode ID payload
1388 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1390 * The server now send IDENTIFY command reply with error
1391 status if client ID in private message is invalid. Affected
1392 file silcd/packet_receive.c.
1394 * Save the server key file with server's IP address in
1395 the filename instead of hostname. The affected file is
1396 irssi/src/silc/core/client_ops.c.
1398 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1403 * Added libtool support for compiling shared objects in
1404 lib/silcsim. Affected file configure.in.pre and
1405 lib/silcsim/Makefile.am. Original patch by cras.
1407 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Pid file configuration, and server's config file fixes
1410 patch by toma. Updated CREDITS file.
1412 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1414 * Fixed silc_client_channel_message to not try to decrypt
1415 the message twice if it resolved the destination client
1416 information. This could cause of dropping one channel
1417 message. Affected file lib/silcclient/client_channel.c.
1419 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1422 lib/silcclient/client.c. This function is used when the SILC
1423 Client is run under some other scheduler, or event loop or
1424 main loop. On GUI applications, for example this may be
1425 desired to used to run the client under the GUI application's
1426 main loop. Typically the GUI application would register an
1427 idle task that calls this function multiple times in a second
1428 to quickly process the SILC specific data.
1430 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1432 * Fixed silc_server_drop() for dropping the supplementary
1433 groups as well, this could cause a security hole on some
1436 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1441 * Write PID file after dropping privileges. Added -F option
1442 to run server on foreground. A patch by debolaz.
1443 Affected files silcd/server.c, silcd/silcd.c.
1445 * Fixed MOTD to return the MOTD file server name. Affected
1446 file silcd/command.c.
1448 * Added INFO command reply handling to the Irssi SILC Client.
1449 Affected file irssi/src/silc/core/client_ops.c.
1451 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Fixed the silc_idcache_list_* routines to really support
1454 the dynamic list. Fixes a crash. Affected file is
1455 lib/silccore/silcidcache.c.
1457 * Fixed the LIST command reply to really call LIST command's
1458 pending callbacks. Affected file silcd/command_reply.c.
1460 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1462 * Update conn->local_entry->nickname after giving NICK
1463 command. Affected file lib/silcclient/command.c.
1465 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1467 * Added the [pid] option to the silcd configuration file
1469 Affected files: serverconfig.[ch] and silcd.c
1471 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Save fingerprint in WHOIS command reply in server.
1474 Affected file silcd/command_reply.c.
1476 * Fixed NICK commands pending callback registration.
1477 Affected file lib/silcclient/command.c.
1479 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Use ++server->cmd_ident when sending commands in server,
1482 instead of random number. Affected file silcd/command.c.
1484 * Fixed GETKEY command reply to call actually GETKEY pending
1485 command callbacks. Affected file silcd/command_reply.c.
1487 * A bit stricter check for nicknames. Check for same nickname
1488 in NICK command also. Affected file silcd/command.c.
1490 * Do not call INFO command everytime client ID changes, only
1491 during first connecting. Affected file lib/silcclient/client.c.
1493 * Set the new nickname only after successful command reply for
1494 NICK command is returned by server. Affected file
1495 lib/silcclient/command.c.
1497 * Remove nicknames from nicklist during server_signoff notify.
1498 Should fix /NAMES bit more. The affected file is
1499 irssi/src/silc/core/silc-channels.c.
1501 * Added `fingerprint' field to the SilcIDListData in the
1502 silcd/idlist.h to hold the fingerprint of the client's
1505 Send the fingerprint of the client's public key in WHOIS
1508 Affected files silcd/command.c, and silcd/idlist.[ch].
1510 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1511 create fingerprint from given data.
1513 * Show the fingerprint of the client's public key in WHOIS.
1514 Affected files irssi/src/module-formats.[ch] and
1515 irssi/src/silc/core/client_ops.c.
1517 * Format the multiple same nicknames also during JOIN and
1518 NICK_CHANGE notifys. Affected file is
1519 lib/silcclient/client_notify.c.
1521 * Do not print error on screen for invalid private message
1522 payload since it can come if someone is sending private
1523 messages with wrong key. Affected file
1524 lib/silccore/silcprivate.c.
1526 * Fixed multiple concurrent /PING crash. Affected file
1527 lib/silcclient/command.c.
1529 * Changed the wrong ID encoding. All IP addresses must be
1530 in MSB first order in encoded format. They were encoded
1531 wrong and was in LSB format. Affected files are
1532 silcd/serverid.c, lib/silcutil/silcutil.c.
1534 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1536 * Call the `connect' client operation through the scheduler
1537 in case of error. Affected file lib/silcclient/client.c.
1539 * Call the `failure' client operation even if the error
1540 occurred locally during a protocol. Affected file is
1541 lib/silcclient/protocol.c.
1543 * Added support of sending LIST command to router from normal
1544 server. This way normal server can get list of all channels
1545 in the network too. Fixed the channel list sending in the
1546 server too. Affected files are silcd/command.c, and
1547 silcd/command_reply.[ch].
1549 * Added silc_server_update_channels_by_server and
1550 silc_server_remove_channels_by_server. They are used during
1551 disconnection of primary router and in backup router protocol.
1552 Affected file silcd/server_util.[ch], silcd/server.c and
1553 silcd/server_backup.c.
1555 * Fixed channel adding to global list in IDENTIFY command
1556 reply in server. Affected file silcd/command_reply.c.
1558 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * If the incoming packet type is REKEY or REKEY_DONE process
1561 that packet always synchronously. Fixes yet another MAC
1562 failed error on slow (dialup) connections. Affected file
1563 lib/silcclient/client.c and silcd/server.c.
1565 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Call check_version SKE callback for initiator too. Affected
1568 file lib/silcske/silcske.c.
1570 * Implemented fix for security hole found in the SKE that was
1571 fixed in the specification few days back; the initiator's
1572 public key is now added to the HASH value computation.
1573 Added backwards support for the old way of doing it too, for
1574 old clients and old servers. Affected file is
1575 lib/silcske/silcske.c.
1577 * Enabled mutual authentication by default in SKE. If initiator
1578 is not providing mutual authentication the responder will
1579 force it. This will provide the proof of posession of the
1580 private key for responder. The affected files are
1581 lib/silcclient/protocol.c and silcd/protocol.c.
1583 * Do not cache anymore the server's public key during SKE.
1584 We do mutual authentication so the proof of posession of
1585 private key is done, and if the server is authenticated in
1586 conn auth protocol with public key we must have the public
1587 key already. Affected file silcd/protocol.c.
1589 * Added new global debug variable: silc_debug_hexdump. If
1590 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1591 file lib/silcutil/silclog.[ch].
1593 * Fixed compilation warning due to char * -> const char *.
1594 Affected files lib/silcutil/silcnet.h, and
1595 lib/silccore/silcauth.[ch].
1597 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Fixed CMODE command when new channel key was created. If
1600 the creation failed the old key was removed. Next time giving
1601 same command would crash the server since the old key was
1602 freed already. Affected file silcd/command.c.
1604 * Fixed the silc_server_announce_get_channels to not crash
1605 on reconnect. Affected file silcd/server.c.
1607 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Added silc_log_set_debug_string function to set a regex
1610 string to match for debug output. Only the function names,
1611 or filenames matching the given debug string is actually
1612 printed. This way it is possible to filter out those debug
1613 strings that user is not interested in.
1615 Fixed a bug in silc_string_regexify.
1617 Affected files lib/silcutil/silclog.[ch], and
1618 lib/silcutil/unix/silcunixutil.c.
1620 * Changed the -d options in both server and Irssi SILC client
1621 to take the debug string as argument. Affected files
1622 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1624 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Added silc_hash_babbleprint to create a Bubble Babble
1627 Encoded fingerprint. The encoding is developed by Antti
1628 Huima (draft-huima-babble-01.txt), and it creates human
1629 readable strings out of binary data. Affected file
1630 lib/silccrypt/silchash.[ch].
1632 * Print the babble print now in addition of fingerprint as well
1633 in Irssi SILC client. Affected files are
1634 irssi/src/fe-common/silc/module-formats.[ch],
1635 irssi/src/fe-common/silc/core/client_ops.c.
1637 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * Fixed a security problem found in SKE. The initiator's
1640 public key too is now added to the HASH hash value creation
1641 which is signed by the responder to create the SIGN value.
1642 This will prevent anyone in the middle to lie to the responder
1643 about the initiator's public key. If this is done now, the
1644 man in the middle will get caught. Updated the protocol
1647 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Better installation directory handling. Configure module
1650 paths and other paths automatically to example_silc* files
1651 in doc/. A patch by toma.
1653 * Fixed compiler warning from MPI library, and from SILC RNG.
1656 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1657 It can be configured with ./configure. A patch by toma.
1659 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Find correct make to use in prepare-clean. A patch by
1662 toma. Affected file prepare-clean.

1683 * Added silc_pkcs_public_key_compare to compare two
1684 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1686 * Check that the client who set the founder mode on the
1687 channel is the same client that is giving the founder
1688 mode to itself. It is done by comparing the saved public
1689 key (it is saved even in the authentication is passphrase).

1697 * Process the DISCONNECT packet through scheduler in the
1698 client library. Affected file lib/silcclient/client.c.
1700 * Fixed the silc_client_packet_parse to not to increase
1701 the packet sequence number if the conn->sock and the
1702 current socket connection is not same. This can happen
1703 for example during key agreement when the conn includes
1704 multiple socket connections (listeners). Affected file
1705 lib/silcclient/client.c.
1707 * The sender of the file transfer request now provides also
1708 the pointer (listener) for the key exchange protocol. If
1709 the listener cannot be created then it sends empty key
1710 agreement and lets the receiver provide the listener.
1712 Added `local_ip' and `local_port' arguments to the
1713 silc_client_file_send. If they are provided they are used,
1714 if not then it will attempt to find local IP address, if
1715 not found or bind fails then the remote client will provide
1718 Affected files are lib/silcclient/client_ftp.c and
1719 lib/silcclient/silcapi.h.
1721 * Extended the FILE SEND command to support defining the
1722 local IP and port for key exchange listener. They are
1723 optional. Affected file irssi/src/silc/core/silc-servers.c.

1727 * Defined to WHOIS command reply the sending of fingerprint
1728 of the client's public key (if the proof of posession of the
1729 corresponding private key is verified by the server).
1730 Updated to the protocol specification.
1732 * Added support of receiving the client's public key's
1733 fingerprint in command reply in client library. Affected
1734 file is lib/silcclient/command_reply.c, and
1735 lib/silcclient/idlist.[ch].
1737 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1790 client library. Affected file lib/silcclient/client_prvmsg.c.
1792 * Do not actually remove the client directly from ID cache
1793 during SERVER_SIGNOFF, but invalidate it. This way we
1794 preserve the WHOWAS info for the client. Affected file
1795 silcd/server_util.c.
1797 * Fixed SERVER_SIGNOFF notify handling in the server. The
1798 server is now able to process incoming SERVER_SIGNOFF notify
1799 for a server that it doesn't even know about. It will remove
1800 the clients provided in the notify. Affected file
1801 silcd/packet_receive.c.
1803 * Check for partial packet in data queue after every packet that
1804 was found from the queue. Return and wait for more data if
1805 there is partial data in queue. Affected file is
1806 lib/silccore/silcpacket.c.
1808 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1823 irssi/src/fe-common/silc/module-formats.[ch].
1825 * Wrote a help file for FILE command.
1827 * Added silc_rng_global_get_byte_fast to get not-so-secure
1828 random data as fast as possible. Random data is read from
1829 /dev/urandom if available and from the SILC RNG if not
1830 available. It is used in padding generation. Affected file
1831 lib/silccrypt/silcrng.[ch].
1833 * All packets in client library are now processed synchronously.
1834 Optimized packet processing a lot. Affected file
1835 lib/silcclient/client.c.
1837 * All server connection packets are processing synchronously
1838 now in server, to optimize packet processing. Affected file
1841 * Include files are installed now only in Toolkit distribution
1842 if make install is given. Affected files: all Makefile.am's.
1844 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Assure that silc_client_notify_by_server_resolve does not
1847 resolve the client information multiple times. If it cannot
1848 be found by the first it cannot be found at all. Affected
1849 file lib/silcclient/client_notify.c.
1851 * Fixed WHOWAS command reply calling. Affected file
1852 lib/silcclient/command_reply.c.
1854 * Removed all references to silc_idlist_get_client from the
1855 Irssi SILC client since that call is internal call used by
1856 the library. The Irssi SILC client will use now client
1857 retrieval functions found in silcapi.h.
1859 * Fixed a bug in resolving nickname info before sending
1860 private message. It used freed memory. Affected file
1861 irssi/src/silc/core/silc-servers.c.

1882 * Added silc_net_localip to return local host's IP address.
1883 Affected file lib/silcutil/silcnet.[ch].
1885 * If key exchange or rekey protocol is active for a connection
1886 parse all packets syncronously since there might be packets
1887 in packet queue that we are not able to process without first
1888 processing packets before them. Affected file silcd/server,
1889 lib/silcclient/client.c.
1891 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1892 whether library should continue processing the packet.
1893 Affected file lib/silccore/silcpacket.h.
1895 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1943 Make sure also that USERS command reply does not resolve
1944 twice information. Affected file is
1945 lib/silcclient/command_reply.c.
1947 Make sure that silc_client_get_clients_by_list does not
1948 resolve twice same information.
1950 * Check for valid client->id in the silc_server_free_client_data.
1951 Affected file silcd/server.c.
1953 * Fixed /GETKEY nick@server not to crash if the server entry
1954 is not found. Affected file lib/silcclient/command.c.

1966 * Call the silc_server_udpate_servers_by_server in the
1967 primary router that comes back online in the backup resuming
1968 protocol. Otherwise it routes packets wrong. Affected file
1969 silcd/server_util.[ch], silcd/server_backup.c.
1971 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1974 lib/silcutil/silcbuffmt.[ch].
1976 * Redefined the SILC packet header to include the padding
1977 length. Affected file lib/silccore/silcpacket.[ch].
1979 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1980 length for maximum padding up to 128 bytes). Affected
1981 file lib/silccore/silcpacket.h.
1983 * Removed all backwards support for old 0.5.x MAC thingies.
1984 The SILC packet header change makes it impossible to be
1985 backwards compatible.
1987 * Send the ENDING packet with timeout in the backup resuming
1988 protocol. This is to assure that all routers has connected
1989 to the primary router. Affected file silcd/server_backup.c.
1991 * Changed the RNG to take the first IV from random data. It
1992 used to take it from zero actually. Changed the RNG also
1993 to use /dev/urandom during session. /dev/random is used
1994 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1996 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1999 (the packet length) encrypted. Affected files aroung the
2000 code tree, lib/silccore/silcpacket.[ch]. Removed the
2001 SilcPacketCheckDecrypt callback. It is not needed anymore
2002 since the silc_packet_receive_process will determine now
2003 whether the packet is normal or special.

2016 * Allow backup router to announce servers. All servers
2017 announced by backup router are added to the global list
2018 automatically. Update hte server's socket to our primary
2019 router also when backup router announces a server.
2020 Affected file silcd/packet_receive.c.
2022 * Do not update the client->router in the function
2023 silc_server_udpate_clients_by_server if the client is on
2024 global list. We might fail to find any specific server
2025 for locally connected clients and local cell clients. They
2026 should still use the `from' and not `to' as client->router.
2027 This fixes backup router resuming protocol. Affected file
2028 silcd/server_util.c.
2030 * Decrease channel statistics count only if the channel
2031 deletion worked. Affected files are silcd/server.c and
2032 silcd/server_util.c.
2034 * Added silc_server_update_servers_by_server to update origin
2035 of all server entries. Used during backup router protocol.

2044 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Assure that router cannot reroute the same channel message
2047 to the sender. Affected file silcd/packet_receive.c.
2049 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Made better checks that the channel message is not sent
2052 to the router it came from. Affected file is
2053 silcd/packet_send.c. Fixed memory leak too.
2055 * Announce informations for incoming router connection, but
2056 only after checking if it is replaced by backup router.
2057 Affected file silcd/packet_receive.c.
2059 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2062 router environment. Affected file silcd/server_backup.c.
2064 * Route packet only to one router in the function
2065 silc_server_packet_send_to_channel. Affected file is
2066 silcd/packet_send.c.
2068 * Fixed silc_server_send_notify_dest to set the broadcast
2069 flag. Fixed the silc_server_send_notify_topic to actually
2070 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2071 Affected file silcd/packet_send.c.
2073 * Changed the SFTP Filesystem interface. Changed the
2074 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2075 the filesystem operation function. The SilcSFTPFilesystem
2076 is now a context that is allocated by all filesystem allocation
2077 functions and it already includes the operations structure
2078 and filesystem specific context. It is given as argument
2079 now to the silc_sftp_server_start. This made the interface
2080 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2081 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2083 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2085 * Changed the backup router adding and getting interfaces
2086 in the server. The router that will be replaced by the
2087 specified backup router is now sent as argument. Affected
2088 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2091 * Added silc_net_addr2bin_ne to return the binary form of
2092 the IP address in network byte order. Affected files

2140 send any data. Affected file lib/silcclient/client.c.
2142 * Implemented the backup router support when the primary router
2143 goes down. The servers and routers can now use the backup
2144 router as new primary router without loosing connectivity.
2146 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2149 in the server to indicate disabled entry. All data read
2150 from the connection will be ignored and no data is sent
2151 for entry that is disabled. Affected files are
2152 silcd/idlist.h, silcd/server.c.
2154 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Created SFTP client and server test programs in the
2157 lib/silcsftp/tests directory.
2159 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Implemented memory filesystem (virtual filesystem) for
2162 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2165 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Implemented the SFTP (SSH File Transfer Protocol) to the
2168 lib/silcsftp. It includes SFTP client and SFTP server
2171 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Moved lib/silccore/silcprotocol.[ch] to the
2174 lib/silcutil library.
2176 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2177 take variable argument list pointer as argument. Affected
2178 file lib/silcutil/silcbuffmt.[ch].
2180 * Added silc_buffer_set function that is used to set data
2181 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2182 Affected file lib/silcutil/silcbuffer.h.
2184 * Changed various routines in the core library to use the new
2185 silc_buffer_set instead of allocating new buffer only for
2188 * Added 64-bit value formatting and unformatting support to the
2189 silc_buffer_[un]format routines. Affected file is
2190 lib/silcutil/silcbuffmt.[ch].
2192 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2193 to includes/bitmove.h.
2195 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2197 * Fixed channel user mode saving in client library. Affected
2198 file lib/silcclient/command[_reply].c.
2200 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Defined the file transfer to the SILC Protocol. Added
2203 new packet type SILC_PACKET_FTP and defined File Transfer
2204 Payload. The mandatory file transfer protocol is SFTP
2205 (SSH File Transfer Protocol). Affected file in addition
2206 of the internet draft is lib/silccore/silcpacket.h.
2208 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2209 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2210 is used as part of backup router protocol when the primary
2211 router of the cell is back online and wishes to resume
2212 the position as primary router.
2214 * Redefined the MAC generation keys in the protocol. The
2215 same key is not used anymore in both direction. Both
2216 direction will now use different keys for sending and
2217 receiving. This fixes a potential security flaw. This
2218 change causes incompatibilities in the protocol.
2220 * Redefined also the MAC computation from the packet.
2221 An packet sequence number is now added to the MAC
2222 computation. This prevents possible replay attacks against
2223 the protocol. This change too causes incompatibilities
2226 Added `sequence' field to the SilcPacketContext to hold
2227 the current sequence number for the packet.
2229 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Added `created' field to the SilcIDListData in the file
2232 silcd/idlist.h to indicate the time when the entry was
2235 * Added `created' field to the SilcChannelEntry too. Affected
2236 file silcd/idlist.h.
2238 * Added `creation_time' aguments to all the announcement functions
2239 in the server. If it is provided then only the entries that
2240 was created after the provided time frame are actually
2241 announced. Affected file silcd/server.[ch].
2243 * The protocol says that the Channel ID's IP address must be
2244 based on the router's IP address. Added check for this in
2245 the silc_server_new_channel when processing incoming New Channel
2246 Payload. Affected file silcd/packet_receive.c.
2248 * Print out the correct version with --version in SILC client.
2249 Affected file irssi/src/silc/core/silc-core.c.
2251 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Fixed WHOWAS command to check for completnes of the client
2254 entry always, not just when the command is coming from client.
2255 Affected file silcd/command.c.
2257 * Added new function silc_server_packet_queue_purge to purge the
2258 outgoing data queue to the network. After the function returns
2259 it is guaranteed that the outgoing packet queue is empty.
2260 Affected file silcd/packet_send.[ch].
2262 * Purge the outgoing packet queue in the rekey protocol's final
2263 callback to assure that all rekey packets go to the network
2264 before quitting the protocol. Affected file silcd/server.c.
2266 * Added silc_client_packet_queue_parse as similar function as
2267 in server to the client library. The affected file is
2268 lib/silcclient/client.c.
2270 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Splitted silcd/server.c and created silcd/server_util.[ch]
2273 for utility functions.
2275 * Added new socket flag SILC_SF_DISABLED to indicate that the
2276 connection is open but nothing can be sent to or received from
2277 the connection. Affected file lib/silcutil/silsockconn.[ch].
2278 The checking for disabled socket is checked in the low level
2279 silc_socket_write and silc_socket_read functions.
2281 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Allow only nicknames and channel names that fits into the
2284 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2286 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * When processing JOIN command reply in server check that if
2289 the channel exists in our global list we'll move it the local
2290 list. Affected file silcd/command_reply.c.
2292 * Fixed the check whether client is joined on the channel already
2293 in JOIN command. Affected file lib/silcclient/command.c.
2295 * Fixed the JOIN command reply to check whether the channel
2296 already exists. Affected file lib/silcclient/command_reply.c.
2298 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Added silc_ske_status_string to map the SKE error numbers
2301 to readable strings. The affected files are
2302 lib/silcske/silcske[_status].[ch].
2304 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Do not show the private channels on the WHOIS channel list
2307 as it is not allowed by the protocol. The affected file is
2310 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Assure that the packet length digged from the actual packet
2313 is something sensible in the silc_packet_decrypt_rest_special
2314 in lib/silccrypt/silcpacket.c.
2316 * Free and NULL the allocated pointer in silc_hmac_alloc if
2317 the HMAC allocation fails. The affected file is
2318 lib/silccrypt/silchmac.c.
2320 * Print the selected security properties to the log files in
2321 the server. Affected file silcd/protocol.c.
2323 * Add SKE's reference counter even if calling the completion
2324 callback manually. Otherwise it goes negative, although it
2325 does not cause any problems. The affected file is
2326 lib/silcske/silcske.c.
2328 * Remove the client entry with short timeout after giving the
2329 KILL command. Affected file lib/silcclient/command.c.
2331 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2332 case all found clients are already disconnected (WHOWAS would
2333 found them) in the server. Affected file silcd/command.c.
2335 * Update the last_receive (time of last data received) to be
2336 updated only when received private or channel message so that
2337 the idle time showed in WHOIS makes more sense.
2339 * Added boolean field `valid' in to the SilcClientEntry in the
2340 client library to indicate whether the entry is valid or not.
2341 This fixes the nickname change bug on channel when changing
2342 the nickname to be same than the old (like nick to Nick) the
2343 nickname formatter doesn't set the new nick anymore to Nick@host.
2344 Affected file lib/silcclient/idlist.[ch].
2346 * Now actually fixed the nickname changing on disconnection.
2347 Added new function silc_change_nick to the Irssi SILC Client.
2348 Affected file irssi/src/silc/core/client_ops.c,
2349 irssi/src/silc/core/silc-nicklist.[ch].
2351 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Check that the public key exists in the GETKEY command before
2354 trying to encode it. Affected file silcd/command.c.
2356 * Print some notifications on received public keys with GETKEY
2357 command in the Irssi SILC Client. Affected files are
2358 irssi/src/fe-common/silc/module-formats.[ch],
2359 irssi/src/silc/core/client_ops.c.
2361 * Use IDENTIFY command to resolve the server information in the
2362 GETKEY command instead of INFO command. Affected file
2363 lib/silcclient/command.c.
2365 * All command reply functions in the client library now calls
2366 the pending command reply callbacks even if an error has
2367 occurred. The server has done this a long time and now it was
2368 time to move the client library to this as well. Now all
2369 errors can be delivered back to the pending command reply
2370 callbacks if necessary. Affected files are
2371 lib/silcclient/command[_reply].[ch].
2373 * Change the nickname on disconnection back to the username
2374 because in reconnect the server will enforce it to it anyway.
2375 Affected file irssi/src/silc/core/silc-servers.c.
2377 * Fixed a config file parsing bug in the Irssi SILC client.
2378 Affected file irssi/src/silc/core/clientconfig.c.
2380 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * When printing the channel mode on JOIN, verify that the
2383 channel key and channel's HMAC are valid. Affected file
2384 irssi/src/silc/core/client_ops.c.
2386 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2389 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2390 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2392 * Removed channel key rekey task deleting from the function
2393 silc_server_save_channel_key. Affected file silcd/server.c.
2394 Added explicit timeout task context instead that is used to
2395 delete the task if we are registering a new task before the
2396 new task has elapsed.
2398 * When channel key rekey occurs the client library now saves
2399 the old channel key for a short period of time (10 seconds) and
2400 is able to use it in case some is still sending channel
2401 messages encrypted with the old key after the rekey. Affected
2402 file lib/silcclient/[idlist.h|client_channel.c].
2404 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Added check to the silc_server_new_id_real to not accept
2407 new ID if it is the sender's own ID. Affected file is
2408 silcd/packet_receive.c.
2410 * Assure that we do not announce ourself or the one we've
2411 sending our announcements when we're router and are announcing
2412 servers to our primary router. Affected file silcd/server.c.
2414 * Fixed silc_server_command_identify_check_client to assemble
2415 correct WHOIS packet. It send corrupted WHOIS packet and
2416 caused problem with router to router connections. Affected
2417 file silcd/command.c.
2419 Fixed also silc_server_command_whois_check the same way
2420 as for the IDENTIFY command.
2422 * Added new SilcIDListStatus to the server in the SilcIDListData
2423 structure. The status now includes the current status of
2424 the entry (like registered, resolved etc.). Affected file
2425 silcd/idlist.[ch]. Defined a bunch of different status types
2426 as well. This replaced the old boolean registered field as well.
2428 Added resolve_cmd_ident field to the SilcClientEntry structure
2429 too so that if the entry is for example being resolved so
2430 another command may attach to the same pending command reply
2431 without requiring to resolve the same entry again. This concept
2432 should optimize the WHOIS and the IDENTIFY resolving under
2433 heavy load by taking away unnecessary resolving for entries
2434 that are being resolved already.
2436 Added support for adding multiple pending commands for one
2437 command idenfier. Affected file silcd/command[_reply].[ch].
2439 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2440 before deleting the data. Otherwise the hash table will have
2441 freed data in comparison functions. Affected file is
2442 silcd/command_reply.c.
2444 * Fixed silc_idlist_replace_client_id to add the new entry to
2445 the cache with NULL nickname. Otherwise there will be invalid
2446 memory as the nickname after the nickname is freed. Affected
2447 file silcd/packet_receive.c.
2449 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2450 saved into wrong slots because the previous number of entries
2451 was not taken into account. Affected file silcd/idlist.c.
2452 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2454 * If we are router and we receive JOIN notify to a channel that
2455 does not have any users then notified client is marked as the
2456 channel founder, as it is it. The affected file is
2457 silcd/packet_receive.c
2459 * Added to the extended hash table API's table_del_*ext functions
2460 the destructor as argument too, so that the caller can decide
2461 which destructor to use or whether to use destructor at all.
2462 Affected file lib/silcutil/silchashtable.[ch].
2464 * Fixed ID Cache purging. It actually deleted the entries from
2465 the hash table after the data was freed. The hash table ended
2466 up comparing freed memory. The affected file is
2467 lib/silccore/silcidcache.c.
2469 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Fixed Irssi SILC client's KILL command's HELP syntax.
2473 * The USERS command now resolves the detailed user information
2474 if the userinfo field is missing. Affected file is
2475 lib/silcclient/command_reply.c.
2477 * Do not print error in silc_file_read if the read file does
2478 not exist. Just silently return NULL. Affected file is
2479 lib/silcutil/silcutil.c.
2481 * Fixed the silc_log_output to not wine about NULL filename
2482 and to not create some bogus " " filename. Affected file is
2483 lib/silcutil/silclog.c.
2485 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Fixed various printing bugs on the user interface in the
2488 Irssi SILC Client. Minor changes that were forgotten from
2491 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Fixed the configure.in.pre and the compilation and distribution
2494 environment to support the new autoconf 2.52. That version is
2495 now required to compile the CVS trunk.
2497 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2500 to generally parse user@fqdn format strings. Affected file
2501 lib/silcutil/silcutil.c.
2503 * Added nickname_format and nickname_force_format fields to the
2504 SilcClientParams structure. The first one defines the format
2505 for the nicknames that the library will enforce if the receives
2506 multiple same nicknames. The second one is boolean value and
2507 can be used to force the library to always enforce the format
2508 to the nicknames regardles whether there are multiple nicknames
2509 or not. This configurable formatting was employed to flexibly
2510 support accessing multiple nicknames from the user interface.
2511 The userinterface can now set the nicknames to what ever format
2512 they prefer. Affected file lib/silcclient/silcapi.h.
2514 Added function silc_client_nickname_format to the file
2515 lib/silcclient/idlist.c. It performs the nickname formatting.
2517 Added new field `hostname´ to the SilcClientEntry context.
2518 It holds the hostname of the client. Affected file is
2519 lib/silcclient/idlist.h.
2521 * Irssi SILC Client sets the nicknames in nick@hostn format.
2522 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2523 irssi/src/silc/core/silc-core.c.
2525 The WHOIS printing now also shows both the real nickname and
2526 the formatted nickname so that user knows how to access the
2527 user if there are multiple same nicknames cached. Affected
2528 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2529 printing formatting too to take the hostname now as a separate
2530 argument. The Affected file is
2531 irssi/src/fe-common/silc/modules-formats.[ch].
2533 * Changed the silc_client_get_clients_local to accept the formatted
2534 nickname as argument. It accepts the real nickname too but the
2535 formatted nickname can be used to find the true entry from
2536 multiple entries. Affected file lib/silcclient/silcapi.h and
2537 lib/silcclient/idlist.c.
2539 * Added nickname_format_parse field to the SilcClientParams.
2540 It is a callback function provided by the application to parse
2541 the nickname out of the formatted nickname string. The library
2542 calls it to get the nickname from the formatted string. Since
2543 the application generally knows better the format of the nickname
2544 string it parses it instead of the library, even though library
2545 encodes the formatted string. If the callback function is not
2546 provided then the library will use the string as is. The
2547 affected file is lib/silcclient/silcapi.h.
2549 * All the nickname strings passed to the client library in
2550 commands are now expected to be formatted nickname strings.
2551 If the command does not support the formatted nickname string
2552 it will assume that the sent string is the actual nickname.
2553 Affected file lib/silcclient/command.c.
2555 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2557 * Added public key authentication support to OPER and SILCOPER
2558 commands in the client library. Affected file is
2559 lib/silcclient/command.c.
2561 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Changed the get_auth_methdod client operation to be asynchronous.
2564 It can be async if the application resolves the authentication
2565 method from the server during the negotiation. Added new
2566 SilcGetAuthMeth completion callback that the application will
2567 call after resolving the authentication method.
2569 Added function silc_client_request_authentication_method that
2570 the application can use to resolve the authentication method
2571 from the server. Added also SilcConnectionAuthRequest callback
2572 that the library will call after the server has replied. The
2573 application can call this function if it does not know the
2574 current authentication method.
2576 Affected files are lib/silcclient/client.c and
2577 lib/silcclient/silcapi.h.
2579 * The Irssi SILC client now automatically resolves the authentication
2580 method incase any configuration information is not present (and
2581 currently there never is). The affected file is
2582 irssi/src/silc/core/client_ops.c.
2584 * Fixed public key authentication from the client library.
2585 Affected file lib/silcclient/protocol.c. Changed also the
2586 protocol specification about the public key authentication in
2587 the connection authentication protocol. The actual data to be
2588 signed is now computed with a hash function before signing.
2590 * Fixed the public key authentication from the server as well.
2591 Affected file silcd/protocol.c.
2593 * Removed the mlock()'s from the memory allocation routines.
2594 Affected file lib/silcutil/silcmemory.c. The ./configure does
2595 not check anymore for the mlock(). Affected file is
2598 * Fixed USERS command in server to allow the execution of the
2599 command for private and secret channels if the client sending
2600 the command is on the channel. Affected file silcd/command.c.
2602 * Fixed silc_client_get_clients_local to return the clients
2603 count correctly. It could return wrong value. Affected file
2604 lib/silcclient/idlist.c.
2606 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2609 types. The assembler optimizations seemed not to like 64-bit
2610 data types. The assmebler optimizations thus are now enabled
2611 also for BSD systems as opposed to only enable them for Linux.
2613 * Do not check for threads at all on BSD systems. Affected
2614 file configure.in.pre.
2616 * Removed -n and -h options from the Irssi SILC Client since
2617 they are not used in silc.
2619 * Fixed the prime generation to assure that the first digit
2620 of the generated random number is not zero since our conversion
2621 routines does not like number strings that starts with zero
2622 digit. If zero digit is seen the random number is regenerated.
2623 This caused some corrupted RSA keys when the zero first digit
2624 was met. Affected file lib/silcmath/silcprimegen.c.
2626 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Fixed WIN32 configuration in the ./configure script.
2629 Fixed to include xti.h on environments that has it.
2630 Patches by Carsten Ilchmann and andrew.
2632 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Changed the silc_id_create_client_id to be collision
2635 resistant. It is now assured that there cannot be created
2636 two same client ID's. I suspect that some weird bugs in
2637 the server were actually caused by duplicate Client IDs.
2638 Affected file silcd/serverid.[ch]. A router receiving
2639 new ID now also assures and informs the sending server
2640 if the ID caused collision.
2642 * Changed the silc_id_create_channel_id to also assure that
2643 there are no collisions.
2645 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Statement about ignoring the Mutual Authentication flag when
2648 performing rekey with PFS was a bit misleading. It is ignored
2649 if it was set in the initial negotiation, it cannot be even
2650 set in the rekey. Fixed in the ke-auth draft. Started the
2651 new versions of the protocol drafts in the doc/.
2653 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Fixed a bug in silc_client_command_identify_save when saving
2656 new channel information. The channel name was no duplicated
2657 and caused crash on exit. Affected file is
2658 lib/silcclient/command_reply.c.
2660 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Fixed the getkey command handling in the server. Send just
2663 empty OK reply to the sender if the key could not be fetched
2664 (but everything else was ok, like the key just was not available).
2665 Changed the public key parameter to optional in the protocol
2666 specs so that empty OK reply can be sent. Affected file
2669 Added a message to Irssi SILC client to tell to user if the
2670 server did not return a public key.
2672 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Fixed a channel key regeneration bug. It registered new
2675 timeout tasks exponentially until all system resources were
2676 used. Affected file silcd/server.c.
2678 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Added the SILC Document generator to the scripts/silcdoc.
2681 It can be used to generate the Toolkit Reference Manual out
2682 of the source tree. Internally it will also use the RoboDoc
2683 generator now imported in util/robodoc.
2685 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Added couple of return's in rekey protocol if error orccurred
2688 during the protocol. The execution must be terminated.
2689 Affected file silcd/protocol.c. Also, terminate the protocol
2690 always with timeout.
2692 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * The client's Client ID was created initally from the wrong
2695 nickname (it could have been in format nick@host) in the
2696 silc_server_new_client. Affected file silcd/packet_receive.c
2698 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Added some SILC_LOG_ERROR's to various error conditions
2701 if client could not be added to ID cache. Affected files
2702 silcd/packet_receive.c and silcd/server.c.
2704 * When client's sock->user_data is freed, NULL also the
2705 client->router and client->connection pointers. Added check
2706 for these pointers being NULL to various places around the
2707 code. Affected file silcd/server.c.
2709 * Added client->data.registered == TRUE checks to various
2710 places around the code to assure that unregistered client's
2711 are not handled when it is not allowed. Affected file
2714 * Added `bool registered' fields to all
2715 silc_idlist_[server|client]_get_* routines to indicate whether
2716 the fetched client needs to be registered or not. Affected
2717 file silcd/idlist.[ch].
2719 * Add your own entry as registered to the ID cache in the
2720 server. Affected file server.c.
2722 * Fixed a bug in silc_server_new_server. The SilcServer was
2723 set as the new server's context instead of SilcServerEntry.
2724 This naturally caused some weird bugs.
2726 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Do not delete the channel rekey task when adding it
2729 for in silc_server_create_channel_key.
2731 * Changed the silc_server_create_channel_key to return
2732 TRUE or FALSE to indicate the success of the channel key
2735 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Fixed MSVC++ project files and added missing files to

2740 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2742 * Do not add TCP_NODELAY flag if the operating system
2743 does not have it defined. Affected files are
2744 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2746 * Fixed buffer overflow from Irssi SILC Client. Affected
2747 file irssi/src/fe-common/core/themes.c.
2749 * Fixed double free in client library in the file
2750 lib/silcclient/client.c when disconnecting from server.
2752 * Applied double free patch from cras to Irssi SILC client.
2753 Affected files irssi/src/core/[modules/expandos].c
2755 * Fixed the disconnection handling to Irssi SILC Client.
2756 The application must call silc_client_close_connection
2757 in ops->connect client operation in case of failure of
2758 the connection. Affected file is
2759 irssi/src/silc/core/client_ops.c.
2761 * Do not set sock->protocol to NULL in the function
2762 silc_client_close_connection after executing the protocol's
2763 final callback since the sock might not be valid anymore.
2764 Affected file lib/silcclient/client.c.
2766 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Do not enable SILC_THREADS if the linking with libpthread
2769 did not happen. Affected file configure.in.pre.
2771 * Added notion to protocol specification that server must
2772 verify the sent authentication payload with CMODE when
2773 setting the channel founder key. Implemented it to the
2774 server. Affected file silcd/command.c.
2776 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Added _EXTRA_DIST SILC distribution variable to the
2779 distributions file. It is used to conditionally add extra
2780 files or directories to the specific distribution. Affected
2781 files ./prepare, Makefile.am.pre and distributions.
2783 Removed the `_' from the start of the distribution names.
2786 * Added README.WIN32 for instructions to compile the Toolkit
2789 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Fixed a double free in disconnection in the server. Affected
2792 file is silcd/server.c.
2794 * Fixed the lib/silcske/groups.c to work now also with GMP
2795 MP library. The string conversion did not work when using
2796 specific base and the base is indicated in the string as well.
2798 * Created win32/ directory which now includes MSVC++ specific
2799 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2800 It will appear only in the toolkit distribution
2802 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * Changed the key material distribution function in case when
2805 the hash output is too short. The data is now concatenated
2806 a bit differently than it used to. Made the change to the
2807 SKE protocol specification.
2809 * Added better GMP detection to configure.in.pre. A patch
2812 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Fixed a minor bug in SKE that might cause some problem on
2815 some platforms. Affected file lib/silcske/silcske.c.
2817 * Added the cookie checking for initiator in the SKE. It checks
2818 that the responder returns the sent cookie unmodified. The
2819 affected file is lib/silcske/silcske.c. Added new SKE
2820 error type INVALID_COOKIE that can be sent during the
2821 negotiation. Fixed some memory leaks as well.
2823 * Added the "invalid cookie" error message to Irssi SILC client's
2826 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Added `task_max' field to the SilcClientParams to indicate
2829 the maximum tasks the scheduler can handle. If set to zero,
2830 default values are used. Affected file lib/silcclient/silcapi.h.
2832 * Fixed memory leaks in silc_client_close_connection. Affected
2833 file lib/silcclient/client.c.
2835 * Added silc_client_del_client_entry to client library to free
2836 all memory of given client entry. Affected file is
2837 lib/silcclient/idlist.[ch].
2839 * Added new functions silc_client_del_channel and
2840 silc_client_del_server to delete channel and server entries.
2841 Affected file lib/silcclient/[silcapi.h/idlist.c].
2843 * Removed silc_client_del_client_by_id from silcapi.h.
2845 * Fixed the INFO command to return the server's own info
2846 correctly when querying by Server ID. Affected file is
2849 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Removed the non-blocking settings in WIN32 code in the
2852 silc_sock_[read/write] and added SleepEx instead. Affected
2853 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2854 of input data is now checked with FIONREAD and ioctlsocket.
2856 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Call silc_schedule_task_del_by_context in the
2859 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2860 Affected file lib/silccore/silcprotocol.c.
2862 * Call silc_protocol_cancel for active protocols in the
2863 silc_server_close_connection if the funtion
2864 silc_server_free_sock_user_data has not been called.
2865 Affected file silcd/server.c.
2867 * Generic tasks cannot be deleted using the del_by_fd
2868 task deleting function since generic tasks does not match
2869 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2871 * Added a notion to SILCOPER help file that the SILCOPER works
2872 only on router server, not on normal server.
2874 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Added for WIN32 support for the new scheduler as well.
2877 Affected file lib/silcutil/win32/silcwin32schedule.c.
2879 * Fixed the SHA1 implementation to work on various platforms.
2881 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2884 API. It is part of the scheduler now. Everything else is
2885 as previously but some functions has changed their names.
2886 Checkout the lib/silcutil/silcschedule.h for the interface.
2887 Updated all applications to use the new interface. Affected
2888 files are lib/silcutil/silcschedule.[ch].
2890 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Found a bug in the SKE implementation. The HASH value,
2893 specified by the protocol, was not computed correctly. The
2894 public key of the responder was not added to the computation
2895 even though it is mandatory. Affected file lib/silcske/silcske.c.
2896 This unfortunately causes incompatibilities with older
2897 clients and servers.
2899 * Added WIN32 specific network init and uninit functions:
2900 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2901 the Winsock2. Affected file lib/silcutil/silcnet.h and
2902 lib/silcutil/win32/silcwin32net.c.
2904 * Set the socket always to nonblocking mode on WIN32 after
2905 reading data or writing data. Affected file is
2906 lib/silcutil/win32/silcwin32sockconn.c.
2908 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Fixed various compilation problems under WIN32. Affected
2911 files lib/silcutil/win32/silcwin32thread.c and
2912 lib/silcutil/win32/silcwin32schedule.c.
2914 * Removed all _internal.h #includes from public header
2915 files. Internal headers must never be included from
2918 Removed also the lib/silcske/payload_internal.h file.
2920 * All include files that may be needed (public and some others
2921 included by the public headers) by application developers are
2922 now copied to the ./includes directory. It does not copy any
2923 internal headers. Affected file Makefile.defines.pre and all
2924 Makefile.am's under lib/ and subdirs.
2926 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Do not change the ~/.silc directory's permissions automatically.
2929 Affected file irssi/src/silc/core/clientutil.c.
2931 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Do not cancel the protocol in silc_server_close_connection
2934 it might cause recursion. Now cancelled in the function
2935 silc_server_free_sock_user_data. Affected file silcd/server.c.
2937 * Fixed the silc_server_remove_clients_by_server to regenerate
2938 the channel keys correctly finally. Added also new function
2939 silc_server_remove_clients_channels to actually do it.
2940 Affected file silcd/server.c.
2942 * Fixed the silc_server_new_channel to not crash by giving
2943 wrong router to the new channel. Affected file is
2944 silcd/packet_receive.c.
2946 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2949 which is given as argument to the silc_client_alloc now.
2950 It can be used to configure the client and set various parameters
2951 that affect the function of the client.
2953 * The USERS command in server did not check whether the channel
2954 is private or secret. Affected file silcd/command.c.
2956 * Added new argument to the USERS command in protocol specification.
2957 The USERS command now can take the channel name as argument
2958 as well. Added support for this in client and server and
2959 updated the protocol specs.
2961 * Completed the GETKEY command in client. It can be now used
2962 to fetch also servers public key not only some clients.
2963 Affected files lib/silcclient/command[_reply].c.
2965 * Added silc_client_get_server to return server entry by the
2966 server name. Affected files lib/silcclient/silcapi.h and
2969 * Redefined the IDENTIFY command in protocol specification to be
2970 more generic. It now can be used to query information about
2971 any entity in the SILC Network, including clients, servers and
2972 channels. The query may be based either the entity's name
2973 or the ID. Added support for this in both client and server.
2975 Affected files silcd/command.c and lib/silcclient/command.c
2976 and command_reply.c.
2978 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2979 the _from_client and _from_server functions. Affected file
2982 * Added silc_client_get_channel_by_id_resolve to the file
2983 lib/silcclient/silcapi.h to resolve channel information by
2984 its ID. Added also silc_client_get_channel_by_id that
2985 does not resolve it from the server.
2987 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Added SilcServerEntry context into the client library
2990 to represent one server. The INFO command now allocates
2991 these to save the resolved server info. For now on the
2992 client library will also keep information about servers,
2993 connected and resolved with INFO.
2995 The INFO command now allocates the SilcServerEntry context
2996 and saves the server info there. The COMMAND_REPLY in
2997 the INFO now returns the parameters to application in
2998 same order as defined in the protocol specification.
3000 The entries are cached in the client->server_cache.
3002 * The INFO command is now issued after received the Client ID
3003 from the server. Affected file lib/silcclient/client.c.
3005 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3006 to the application as the mode changer might be server.
3007 It is guaranteed that NULL is not returned anymore to the
3008 application. Affected file lib/silcclient/client_notify.c.
3010 The ID Type is now also passed to the application so that
3011 it can check whether the returned entry is SilcClientEntry
3014 Added new function silc_client_get_server_by_id to return
3015 the server entry by ID. Affected files are the
3016 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3018 * Do not create the channel in the Irssi SILC Client when issuing
3019 the JOIN command but when received the sucessful JOIN command
3020 reply. Otherwise the channel might get created even though we
3021 could not join it. The Affected file is
3022 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3024 * Fixed a channel joining bug in router. The router must also
3025 check the channel modes, invite and ban lists etc. when serving
3026 the JOIN command sent by normal server. Affected file is
3027 silcd/command.c. The router now resolves the client's
3028 information from the server who sent the JOIN command if it
3029 does not know it, and processes the JOIN command only after
3032 * Changed the SilcCommandCb to take new argument; void *context2.
3033 Affected file lib/silccore/silccommand.h
3035 The second argument in the command callbacks in the server now
3036 includes the SilcServerCommandReplyContext if the command was
3037 called as pending command callback from the command reply.
3038 Otherwise it is NULL. When called as pending the status of the
3039 command reply will be checked and if it was erronous the
3040 error will be sent to the original sender of the command.
3041 This way the client always receives the error messages even
3042 though the server was actually the one who received the error
3043 when it resent the command to router, for example. Affected
3044 files silcd/command[_reply].[ch].
3046 * Fixed sending WHOWAS command's error message to client if
3047 the requested client could not be found. It was missing.
3050 * Changed the CMODE and CUMODE commands reply arguments in the
3051 protocol specification. The Channel ID is now sent in both
3052 of the commands to identify the channel. Implemented this
3053 new feature to the client and server. Affected files
3054 lib/silcclient/command_reply.c and silcd/command.c.
3056 * Made better checks for invite and ban lists in the JOIN
3057 command in server. Affected file silcd/command.c.
3059 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * The server now performs the incoming host IP/DNS lookup
3062 using the silc_socket_host_lookup and thus does not block
3063 the server anymore. Affected file silcd/server.c.
3065 * Completed the multi-thread support for SILC Scheduler in
3066 the lib/silcutil/silcschedule.c.
3068 * Fixed the configure.in.pre to detect the pthread correctly
3071 * Fixed a deadlock in silc_task_queue_wakeup in the file
3072 lib/silcutil/silctask.c.
3074 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3076 * Added new function silc_schedule_wakeup that is used in
3077 multi-threaded environment to wakeup the main thread's
3078 schduler. It needs to be used when a thread adds a new task
3079 or removes a task from task queues. After waking up, the
3080 scheduler will detect the task queue changes. If threads
3081 support is not compiled in this function has no effect.
3082 Implemented the wakeup mechanism to both Unix and WIN32
3083 systems. Affected files are lib/silcutil/silcschedule.[ch],
3084 lib/silcutil/unix/silcunixschedule.c and the
3085 lib/silcutil/win32/silcwin32schedule.c.
3087 * Added new function silc_task_queue_wakeup to wakeup the
3088 scheduler by the specified task queue. Affected file
3089 lib/silcutil/silctask.[ch].
3091 * The silc_socket_host_lookup_start now wakes up the scheduler
3092 after adding the timeout task. Affected file is
3093 lib/silcutil/silcsockconn.c.
3095 * The silc_socket_host_lookup is synchronous now if the threads
3096 support is not compiled in. However, the callback is still
3097 called asyncronously through the scheduler, anyway. Affected
3098 file lib/silcutil/silcsockconn.c.
3100 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Added new function silc_socket_host_lookup to perform
3103 asynchronous IP and FQDN lookups for the socket connection.
3104 Affected files lib/silcutil/silcsockconn.[ch].
3106 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3109 that may or may not compile the mutex support in.
3111 Changed the silc_mutex_alloc interface. It allocates the
3112 mutex now to the sent pointer and returns TRUE or FALSE.
3114 Affected file lib/silcutil/silcmutex.h.
3116 * Wrote the SILC Task Queue interface to support multi-threads.
3117 Affected file lib/silcutil/silctask.[ch].
3119 * Wrote the SILC Scheduler to support multi-threads. Affected
3120 file lib/silcutil/silcschedule.c.
3122 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3125 in lib/silcutil/win32/.
3127 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Defined SILC Mutex API and SILC Thread API and implemented
3130 them for Unix. Affected files are
3131 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3132 lib/silcutil/unix/silcunixmutex.c and
3133 lib/silcutil/unix/silcunixthread.c.
3135 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Fixed the silc_server_remove_clients_by_server's channel
3138 key re-generation. The hash table handling was incorrect
3139 and would not work with many channels. Affected file is
3142 * Fixed some memory leaks around the server code.
3144 * Rewrote the silc_server_get_users_on_channel to support IPv6
3145 based Client ID's. Affected file silcd/server.c.
3147 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3148 specification. However, a separate document must be written
3149 to define the detailed signing procedure and the payload
3150 associated with the flag. Defined the flag to the
3151 lib/silccore/silcchannel.h as well.
3153 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Changed the dynamic tables to static size tables in the
3156 lib/silccrypt/silchmac.c.
3158 * Removed GCC dependencies from the code. A patch by cras.
3160 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3162 * Do not show the error "Error receiving packet bla bla"
3163 in server if it really was not an error (-2 means that reading
3164 is pending). Affected file silcd/server.c.
3166 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3168 * Fixed a possible crash in silc_server_remove_clients_by_server
3169 in silcd/server.c. Fixed there also some memory leaks.
3171 * Fixed the silc_idlist_replace_client_id. It could replace
3172 wrong key in the hash table. Affected file silcd/idlist.c.
3174 * Do not check whether there are global users on the channel
3175 if the channel->global_users is FALSE. Affected functions
3176 silc_server_remove_from_one_channel and
3177 silc_server_remove_from_channels in silcd/server.c. Also,
3178 do not check if the removed client is local as we can be
3179 sure that global client was not removed from the channel
3180 and checking for global users is not needed.
3182 * The silc_server_remove_clients_by_server now re-generates
3183 the channel keys correctly for those channels that had
3184 clients removed from them. Affected file silcd/server.c.
3186 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Found the reason of random crashes in the server. We weren't
3189 ignoring the SIGPIPE signal (which can be sent in write())
3190 and it crashed the server. Affected file silcd/silcd.c.
3192 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Assure that sock->user_data is not NULL in the function
3195 silc_server_packet_send in silcd/packet_send.c.
3197 * Disconnect the remote connection if it could not be added
3198 to any ID lists in the server. The affected file is
3201 * Check in silc_server_packet_send[_real/dest] that the
3202 socket is not disconnecting and ignore the data if it is.
3203 Affected file silcd/packet_send.c.
3205 * Define inline to __inline on native WIN32 compilation.
3206 Affected file includes/silcwin32.h.
3208 * Added some explicit type casts for inline code since MSVC
3209 require them. Affected files lib/silcutil/silcbuffer.h,
3210 lib/trq/silcdlist.h and lib/trq/silclist.h.
3212 * Print warning in log files from now on if the packet
3213 decryption fails. Affected file silcd/server.c.
3215 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Changed the `say' client operation's interface to accept
3218 new `type' argument to indicate the type of the message sent
3219 by the library. The application may filter the library's
3220 messages according the type. The affected file is the
3221 lib/silcclient/silcapi.h.
3223 * Added two new functions to lib/silcclient/silcapi.h:
3224 silc_client_del_client and silc_client_del_client_by_id.
3225 Affected file lib/silcclient/idlist.c.
3227 * Moved the clientincludes.h from includes/ to silc/ and
3228 serverincludes.h from includes/ to silcd/.
3230 * The modes for the CMODE and CUMODE are now passed as
3231 uint32 for application with COMMAND_REPLY. The affected
3232 file is lib/silcclient/command_reply.c.
3234 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * /WHOIS without arguments shows client's own information.
3237 Affected file lib/silcclient/command.c.
3239 * Changed PING to not accept any arguments. The specs
3240 says that client can ping only the connected server so
3241 requiring an argument is not needed. Affected file is
3242 lib/silcclient/command.c.
3244 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3246 * Fixed a fatal bug in private message sending and reception
3247 encryption and decryption when using private message keys.
3248 The implementation was incorrect and did not follow the
3249 specification. It causd that some of the message were
3250 lost since it did not use the sending and receiving keys
3251 as the protocol suggests. This has been fixed and will cause
3252 incompatibilities with older clients when sending private
3253 message encrypted with private message keys. Affected files
3254 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3255 and various other in Irssi SILC Client.
3257 Added `responder' boolean argument to the functions
3258 silc_client_add_private_message_key[_ske] to indicate when
3259 the key is added as responder or initiator of the key
3262 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Removed the silc_ske_check_version function and created
3265 a SilcSKECheckVersion callback. Added also a function
3266 silc_ske_set_callbacks that is now used to set all SKE
3267 callbacks. The callback functions are not given to
3268 the SKE functions anymore, but this function is used to
3271 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3273 * Added `silc_version' argument to the silc_client_alloc
3274 to define the version of the application for the library.
3275 The library will use the version string to compare it
3276 against the remote host's (usually a server) version
3277 string. Affected file lib/silcclient/silcapi.h
3279 * Added the KE protocol context to Key Agreement context
3280 in client library so that we can abort the SKE if it
3281 is in process when we get timeout. Affected file is
3282 lib/silcclient/client_keyagr.c.
3284 * Do not resolve the client ID forever if it returns in the
3285 first time that such client does not exist. This was done
3286 for example with private message. Affected file is
3287 lib/silcclient/client_prvmsg.c.
3289 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Do not add regex.h for WIN32. The affected file
3292 includes/silcincludes.h.
3294 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3295 not work yet 100%. It generates the DLL's automatically
3296 when compiling with --with-win32 under cygwin.
3298 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3300 * lib/contrib/regex.c is not compiled on WIN32.
3302 * Added silc_net_get_socket_opt function to the
3303 lib/silcutil/silcnet.h.
3305 * Added includes/silcwin32.h for WIN32 specific includes
3308 * Do not use ptime structure or any of the posix process
3309 functions on WIN32 in lib/silccrypt/silrng.c.
3311 * Added silc_gettimeofday to provide generic function
3312 for struct timeval on all platforms. Added the function
3313 to lib/silcutil/silcutil.h.
3315 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3318 library as they clearly belong there. As a plus side we
3319 can make the actual socket connection routines platform
3322 Added also new generic function silc_socket_read and
3323 silc_socket_write (that used to be silc_packet_[read/write].
3324 The implementation of these are platform specific.
3326 * Added WIN32 specific routines of silc_socket_[read/write]
3327 to lib/silcutil/win32/silcwin32sockconn.c.
3329 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Added preliminary support for native WIN32 compilation under
3332 cygwin (using the -mno-cygwin option for GCC) to the
3333 ./configure.in.pre. The --with-win32 now prepares the
3334 compilation for native WIN32.
3336 * Rewrote the SILC Scheduler interface in the file
3337 lib/silcutil/silcschedule.h. The scheduler is now context
3338 based and does not have anymore any global static scheduler.
3339 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3340 and created lib/silcutil/win32 directory for WIN32 based
3343 * Added Unix specific network routines to the
3344 lib/silcutil/unix/silcunixnet.c and the old
3345 lib/silcutil/silcnet.c includes now only generic routines.
3347 Added WIN32 specific network routines to the
3348 lib/silcutil/win32/silcwin32net.c.
3350 * Added Unix specific utility functions from the
3351 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3353 * Added WIN32 SILC Scheduler to the file
3354 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3357 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Do not handle JOIN notify in the server if the target client
3360 is not registered (idata->registered == FALSE). The affected
3361 file is silcd/packet_receive.c.
3363 * Update the nickrec->founder in event_cumode in the Irssi SILC
3364 client. Affected file irssi/src/silc/core/silc-channels.c.
3366 * Fixed the CUMODE_CHANGE notify handling in the server when
3367 server and router are announcing their clients on channels.
3368 Now the mode changes are saved and notified correctly. The
3369 affected file is /silcd/packet_receive.c.
3371 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3372 They really did not replace the cache entry in the ID Cache.
3373 Now they do that. Affected file silcd/idlist.c.
3375 * Fixed the KICK notify handling in the Irssi SILC client to
3376 update the channel records so that the kicked client does not
3377 appear to be on the channel. The affected file is
3378 irssi/src/silc/core/silc-channels.c.
3380 * Always update the conn->current_channel when executing command
3381 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3383 * Fixed the KILL notify handling in Irssi SILC client to remove
3384 the killed client on all channels.
3386 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Fixed the silc_parse_command_line to remove extra spaces
3389 from the start and end of the arguments. Affected file is
3390 lib/silcutil/silcutil.c.
3392 * Cancel and free any active protocol in the function
3393 silc_server_close_connection. Affected file silcd/server.c.
3395 * Cancel and free any active protocol in the function
3396 silc_client_close_connction. Affected file is
3397 lib/silcclient/client.c.
3399 * Do not execute the KILL command for clients that are in
3400 history (ie. they are not in the network). Affected file is
3403 * Fixed KILL notify handling, client does not crash anymore.
3404 Affected file irssi/src/silc/core/silc-channels.c.
3406 * Reduced the default packet buffer size from 2048 to 1024 in
3407 lib/silccore/silcpacket.c.
3409 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3410 counter to the SKE context that is incresed when the SKE library
3411 performs async operation outside the library. If the outside
3412 process frees the SKE context and FREED status will be set
3413 and the library will detect after the sync operation that the
3414 libary is freed. The affected files are
3415 lib/silcske/silcske[_status].[ch].
3417 * Resolve the client entry information in the function
3418 silc_client_channel_message to assure that NULL pointer is not
3419 passed as client entry to the application. */
3421 * Fixed the task timeout calculation to assure that there is
3422 never negative timeouts. The affected file is
3423 lib/silcutil/silcschedule.c.
3425 * Fixed the channel user mode notification sending in server.
3426 It was sent point-to-point to the router (or to server by router)
3427 but it needs to be destined to a channel. The routines now
3428 supports sending the channel user mode notifys to the channels
3429 when announcing clients and channels. Affected files are
3430 silcd/server.c and silcd/packet_receive.c.
3432 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3433 It did not actually replace the old channel entry in the cache.
3434 Affected file lib/silcclient/client_notify.c.
3436 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3438 * Fixed a possible crash in silc_packet_send_prepare. It now
3439 assures always that there is enough space in the buffer and
3440 at the tail area of the buffer (for MAC).
3442 Fixed the inbound buffer reallocation in silc_packet_read.
3443 It was old code and did not handle the reallocation correctly.
3446 The affected file is lib/silccore/silcpacket.c.
3448 * Fixed buffer overflow in silc_parse_nickname in the file
3449 lib/silcutil/silcutil.c.
3451 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * make install generates new server keys only if there is not
3456 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3459 Added check that if the NOREPLY is set then we will not send
3460 the away message. This avoids infinite loop of away messages
3461 if both clients are away. The affected file is
3462 lib/silcclient/client_prvmsg.c.
3464 * Fixed client crash if /NICK was given without arguments.
3465 Affected file lib/silcclient/command.c.
3467 * Server does not send the invite list in INVITE command back
3468 to the client if the list was not altered. Added this notion
3469 to the protocol spec as well. Affected file silcd/command.c.
3471 Fixed possible crash in INVITE command by checking the
3472 value of silc_server_get_client_route command.
3474 * Fixed the INVITE notify type handling. The arguments are now
3475 taken in correct order and client does not crash. The affected
3476 file is irssi/src/silc/core/silc-channels.c.
3478 Removed the "Inviting xxx to channel" message from the
3479 client library away and let the application handle it.
3480 Affected file lib/silcclient/command.c. Added that message
3481 to Irssi SILC client's message formats.
3483 * Fixed CMODE command crash in client. It now checks the
3484 amount of arguments correctly and does not crash. The affected
3485 file is lib/silcclient/command.c.
3487 * Do not create new channel automatically in silc_channels_join
3488 but check whether the channel by that name already exists.
3489 Affected file irssi/silc/core/silc-channels.c.
3491 * Do not send the SERVER_SIGNOFF to router if the disconnected
3492 entity was the router. Affected file silcd/server.c.
3494 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3495 SILC client as it was missing from there.
3497 Added the handling of the KICK notify to the Irssi SILC client
3498 as it was missing. Added "you have been kicked" message to
3499 Irssi SILC client's message modules formats.
3501 Added the handing of the KILL notify to the Irssi SILC client
3502 as it was missing. Added the kill message module formats
3505 The affected file is irssi/src/silc/core/silc-channels.c.
3507 * The router did not save the channel mode the server announced.
3508 Affected file silcd/packet_receive.c.
3510 * Fixed a possible crash in INFO command in server. If the
3511 server did not provide the server info it crashed. Affected
3512 file silcd/command.c.
3514 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Fixed the GETKEY command in the server to check also the
3517 global list. Otherwise the GETKEY would not work correctly
3518 in normal SILC server. Affected file silcd/command.c.
3520 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Fixed GETKEY crash, it crashed if the command did not succseed.
3524 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3527 is now real and not just an macro interface to GMP.
3529 Removed the entire GMP from the source tree and imported new
3530 NSS MPI library instead. Reason for removing GMP is that it is
3531 extremely large and compiles extremely slow. The NSS MPI
3532 is only a few files and compiles in less than 10 seconds.
3533 The speed is also about the same as GMP. The MPI is imported
3534 to lib/silcmath/mpi.
3536 If the system has GMP installed we will still use the GMP.
3537 If it is not then the NSS MPI will be compiled.
3539 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Merged a long nickname (127 characters long) crash bugfix from
3542 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3544 * Merged a freed memory reference bugfix from Irssi CVS tree.
3545 Affected file irssi/src/core/commands.c.
3547 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Added the server's public key sving and verification to the
3550 server when performing the SKE. This was missing and the
3551 remote server's (or router's) public key was accepted without
3552 checking whether we have it previously or trust it at all.
3553 Affected file silcd/protocol.c.
3555 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Check in the silc_server_timeout_remote if protocol is active
3558 and make sure that the protocol's final callback is called so
3559 that all memory if freed. Affected file silcd/server.c.
3561 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * silc_server_whois_send_reply crashed the server if the nickname
3564 was 127 characters long. Affected file silcd/command.c.
3566 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Added sanity check to the silc_server_new_client. If the hostname
3569 is provided inside username then check that the provided hostname
3570 really is the same as the resolved one. If the hostname was not
3571 resolved then check it from the public key. Affected file is
3572 silcd/packet_receive.c.
3574 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3575 if the server disconnected us and the connection is not valid
3576 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3578 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3579 the library to the lib/silcutil/silcutil.[ch].
3581 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Close log file after open. Affected file
3584 lib/silcutil/silclog.c.
3586 * Check whether sock == NULL in silc_client_send_packet and return
3587 if it is. Affected file lib/silcclient/silcclient.c.
3589 * Check rec->entry == NULL in the Irssi SILC Client before
3590 sending the channel message. Affecte file is
3591 irssi/src/silc/core/silc-servers.c.
3593 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Merged a splitted window bugfix from Irssi CVS tree. The
3596 affected file is irssi/src/fe-text/textbuffer-view.c.
3598 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3599 It did not print nickname.
3601 * Improved the distributions system a bit.
3603 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3606 irssi/src/fe-text/gui-window.c.
3608 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3609 to in-active server. The affected file is
3610 irssi/src/silc/core/client_ops.c.
3612 * Resolve the client in USERS command reply if the entry does
3613 not have username resolved. The affected file is
3614 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3615 command to WHOIS command to really resolve stuff. The USERS
3616 is not used any more in any critical section so WHOIS can
3617 be used even though it might be slower than IDENTIFY.
3619 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3622 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Changed the protocol API a bit more consistent in the
3625 lib/silccore/silcprotocol.[ch].
3627 * Changed the following headers to ROBODoc format:
3629 lib/silccore/silcpayload.h
3630 lib/silccore/silcprotocol.h
3631 lib/silccore/silcsockconn.h
3633 All core library headers are now formatted.
3635 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Fixed a bug in Irssi SILC client; do not show that you are
3638 server/router operator if you really are not. Affected file is
3639 irssi/src/silc/core/client_ops.c.
3641 * Renamed silc_command_free_payload to silc_command_payload_free.
3642 Affected file lib/silccore/silccommand.h
3644 * Added silcmath.h to include the prototoypes of various routines
3645 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3648 * Changed the following headers to ROBODoc format:
3650 lib/silccore/silcchannel.h
3651 lib/silccore/silccommand.h
3652 lib/silccore/silcid.h
3653 lib/silccore/silcidcache.h
3654 lib/silccore/silcmode.h
3655 lib/silccore/silcnotify.h
3656 lib/silccore/silcpacket.h
3657 lib/silcmath/silcmath.h
3659 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Added checking to the server code not to start the server if
3662 ciphers and stuff are not configured properly. Affected files
3663 silcd/serverconfig.[h] and silcd/server.c.
3665 * Changed the layout of the header files of the public interfaces
3666 in the SILC libraries. The new layout supports ROBODoc
3667 documentation tool (and some others) so that it is easy to create
3668 a library reference manual. All the other headers and source
3669 code must still follow the CodingStyle document. Also source
3670 code must not include these ROBODoc stuffs, only the headers.
3671 Furthermore, all public interface headers must now be named
3672 by using `silc' prefix, example: silcapi.h, silccipher.h.
3673 Some files were renamed due to this. All the other headers
3674 must not be used as public interfaces. I will update the
3675 CodingStyle document later. Changed following headers, so far:
3677 lib/silcclient/silcapi.h
3678 lib/silccore/silcauth.h
3679 lib/silccore/silcprivate.h
3680 lib/silccrypt/silcdh.h
3682 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Removed silc_client_packet_send_flush from the client library
3687 as it is not needed. Affected file lib/silcclient/client.[ch].
3689 * Added printing of message of unresolved authentication method
3690 to the Irssi SILC client. Added it to the module formats.
3691 Removed the same message from the client library.
3693 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added new distribution feature, DISTLABEL. Every distribution
3696 can define own preprocessor label that can be used in the
3697 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3698 file distributions, acconfig.h.pre and prepare.
3700 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Added Makefile.defines_int to include the actual definitions
3703 for Makefile.defines.in. Tested the new distribution system,
3704 created distributions and tested installation.
3706 * Added AWAY message printing to the Irssi SILC client. Added
3707 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3709 * Added SCONNECT command to call the SILC's CONNECT command.
3710 Cannot use CONNECT directly since Irssi uses that internally.
3711 Affected file irssi/src/silc/core/silc-servers.c.
3713 Added ACTION local command. It is same as ME command but takes
3714 the channel as mandatory argument.
3716 Rewrote some of the Irssi's help files to suite for SILC
3719 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3721 * Added Makefile.defines[.in] that should for now on be included
3722 in all Makefile.am file in the source tree. That file includes
3723 all common compilation definitions for SILC source tree.
3725 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Minor changes to the ./prepare script to change the package
3728 name according the distribution name to the configure.in.
3730 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3732 * Created new distribution system. Added file `distributions'
3733 that defines all the distributions that can be created out of
3734 the SILC source tree. The ./prepare script now reads that
3735 file to determine how to prepare the distributions. The
3736 first argument to the ./prepare is the name of the distribution
3737 and second is the version of the distribution. If given
3738 without arguments it creates the default (toolkit) distribution
3739 with the default version (defined in ./prepare).
3741 All Makefile.am files that are subject to the distributions
3742 are now named as Makefile.am.pre. These are ./Makefile.am
3743 and lib/Makefile.am. Others may be changed later.
3745 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Added invite list, ban list, some key management and connection
3748 error message printing to module formats in the Irssi SILC client.
3750 * Added new silc_client_set_away_message to set the away message
3751 that is back to the person who sent private message. The
3752 affected file lib/silcclient/silcapi.h and the
3753 lib/silcclient/client_prvmsg.c.
3755 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Fixed the private message sending in the Irssi SILC client,
3758 added local command KEY to the Irssi SILC client.
3760 Added key management and key agreement message formats to the
3761 irssi/src/fe-common/silc/module-formats.[ch].
3763 Added USERS (alias WHO) printing, server/router operator
3764 indication and LIST command printing to the module formats.
3766 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Fixed channel joining notify handling, cumode notify handling
3769 from Irssi SILC client.
3771 * Added SILC specific module-formats to the Irssi SILC client so
3772 that SILC specific message hilighting, colors etc is possible.
3773 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3775 Added channel mode, channel user mode, actions, notices,
3776 whois and whowas printing to the the module-formats.c.
3778 * Fixed a bug in channel deletion in the server. The channel
3779 is not left to the cache even if the channel founder auth mode
3780 is set when there are no users anymore on the channel. Affected
3781 file silcd/server.c.
3783 * The silc_net_localhost now resolves the entire hostname including
3784 the domain name. Affected file lib/silcutil/silcnet.c.
3786 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3788 * Changed the ask_passphrase client operation to be ascynchronous.
3789 It has now a completion callback and a context that the
3790 application must call after it has got the passphrase from
3791 the user. Affected files lib/silcclient/silcapi.h,
3792 lib/silcclient/protocol.c, lib/silcclient/command.c and
3795 Added SilcAskPassphrase callback that the application calls
3796 to deliver the passphrase to the library.
3798 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3799 The public key verification and especially a certificate
3800 verification is asynchronous procedure.
3802 Added new SILC_SKE_STATUS_PENDING status to indicate the
3803 request is pending and a callback will be called to finalize
3806 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3807 indicate that remote end did not send its public key (or
3808 certificate), even though we require it. Added check for this
3809 condition in the SKE. This was a security bug, now fixed.
3811 Defined new SilcSKEVerifyCbCompletion callback that is called
3812 when the verification process is completed.
3814 The affected files lib/silcske/silcske_status.h and
3815 lib/silcske/silcske.[ch].
3817 * Changed the verify_public_key client operation to be async
3818 as well. Defined SilcVerifyPublicKey callback that is used to
3819 indicate the success of the public key verification process.
3821 Changed the server and client to use the new async client
3824 * Changed the Irssi SILC client's internal scheduler to be called
3825 twice as many times as it used to be. As a result the client
3826 should be a bit faster now. Affected file is
3827 irssi/src/silc/core/silc-core.c.
3829 * Added support to Irssi SILC client of asynchronous public key
3830 verification and passphrase inquiry. Affected file is
3831 irssi/src/silc/core/silc-core.c.
3833 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * Do not say "You have left channel %s" in client library.
3836 Moved it to the application. Affected files are
3837 lib/silcclient/command.c and silc/client_ops.c.
3839 * Fixed silc_client_get_clients. Command context was not
3840 duplicated and was freed memory in the callback. Affected
3841 file lib/silcclient/idlist.c.
3843 * Do not say "you are now talking..." on JOIN command in the
3844 client library. The appliation must handle it.
3846 * Do not say ".. changed topic to" in command reply in the
3847 client libary. The application must handle it.
3849 * Fixed TOPIC command sending in the client library.
3851 * Fixed a memory leak in silc_client_command_free in the file
3852 lib/silcclient/command.c.
3854 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Imported a modified version of Irssi client to the source tree.
3857 The Irssi will be used to create a new client called
3858 Irssi SILC. Imported to irssi/.
3860 Added silc_core_init_finish function to the Irssi. Affected
3861 file irssi/configure.in.
3863 A lot changes in the Makefile.ams around the irssi tree.
3865 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Do not rehash if the new size is same as the old size of the
3868 hash table, in the silc_hash_table_rehash*. The affected file
3869 lib/silcutil/silchashtable.c.
3871 * Replaced hash_table_del_by_context calls from the server
3872 (when channel->user_list and client->channels) to the
3873 hash_table_del as it is sufficient and faster.
3875 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3877 * Added silc_hash_table_list, silc_hash_table_get and the
3878 SilcHashTableList structure to provide an alternative way to
3879 traverse the hash table. The affected files are
3880 lib/silcutil/silchashtable.[ch].
3882 * Changed the server's idlist routines to use the hash table
3883 routines to optimize the code.
3885 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Replaced the client entry's `channel' list and channel entry's
3888 `user_list' list to hash tables for optimized lookup. Changed
3889 the code to use the hash table interface around the code.
3890 Affected file lib/silcd/idlist.[ch].
3892 * Added `auto_rehash' boolean argument to the function
3893 silc_hash_table_alloc to indicate whether the hash table should
3894 auto-rehash when it thinks is appropriate time. It will
3895 increase the hash table size if the there is twice as much
3896 entries in the table than the size of the table, and will
3897 decrease the size if there are twice as less entries than
3898 the size of the table.
3900 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3904 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * silc_idcache_purge_by_context deletes the entry now by context
3907 as it is supposed to do. Affected file lib/silccore/idcache.c.
3909 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3910 client is not anymore valid (WHOWAS givens the info) and not
3911 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3913 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3915 * Removed the `data' and `data_len' arguments from the ID Cache
3916 interfaces and added `name' argument. ID Cache does not handle
3917 anymore the binary data only a names associated with given ID.
3919 * When hashing a Client ID with silc_hash_id the entire ID is
3920 not hashed anymore, instead only the hash of the Client ID is
3921 hashed. This way we can access the Client ID from the cache
3922 with Client ID but with the hash of the ID (which is a hash of
3923 the nickname) as well without any difference in performance.
3925 Added also silc_idcache_find_by_id_one_ext to do one on one
3926 searching when we have the actual ID. Added also function
3927 silc_hash_client_id_compare. The affected files are
3928 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3930 * When hashing the name associated with a ID it is always done
3931 in lowercase. This way we can access the cache without worrying
3932 about case-sensitivity, even though, for example nicknames are
3935 * Fixed a bug in server with channel message sending. It put
3936 wrong ID type as destination ID. The affected file
3937 silcd/packet_send.c.
3939 * silc_idcache_del_by_context now deletes from all hash tables
3940 by context. Affected file lib/silccore/idcache.c.
3942 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Changed the client library to use the new ID Cache interface.
3945 Changes around the source tree.
3947 * Added silc_hash_table_rehash_ext to rehash with specific
3948 hash function. Affected file lib/silcutil/silchashtable.[ch].
3950 * Added silc_hash_string_compare to compare two strings in the
3951 hash table. Affected file lib/silcutil/silcutil.[ch].
3953 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Added new function silc_idcache_del_by_context into the
3956 lib/silccore/idcache.[ch].
3958 * Changed the server's ID list routines to use the new ID Cache
3959 interface. Changes around the source tree.
3961 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Added silc_hash_table_del[_by_context]_ext functions in to the
3964 lib/silcutil/silchashtable.[ch].
3966 Removed silc_hash_table_find_all* routines and added new
3967 silc_hash_table_find_foreach to replace them.
3969 Added silc_hash_table_replace_ext function as extended
3970 replacing function. Separated the simple hash table interface
3971 from the extended hash table interface in the file
3972 lib/silcutil/silchashtable.h.
3974 * Fixed minor bugs and changed it to use some of the new
3975 hash table functions in lib/silccore/idcache.c
3977 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Added new function silc_hash_table_find_all to return all keys
3980 in the hash table by the specified key. As the hash table is
3981 collision resistant it also makes it possible to have several
3982 duplicate keys in the hash table. This function may be used to
3983 find all of the keys from the hash.
3985 Added user_context arguments to the SilcHashFunction,
3986 SilcHashCompare and SilcHashDestructor to deliver user specified
3989 Added new fuctions silc_hash_table_find[_all]_ext to do
3990 extended lookup with specified hash and compare functions and
3991 specified user contexts.
3993 Added new function silc_hash_table_add_ext to add the key
3994 with specified hash function and user context.
3996 Added new function silc_hash_table_foreach to traverse all
3997 entrys in the hash table. Added SilcHashForeach callback
4000 Added new function silc_hash_table_del_by_context to delete
4001 the entry only if the context associated with the key matches.
4003 Affected files are lib/silcutil/silchashtable.[ch].
4005 * Removed silc_hash_[server/client/channel]_id and added just
4006 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4007 silc_hash_id_compare to compare two ID's using as the hash table
4008 comparison function. Added also silc_hash_data to hash
4009 binary data and silc_hash_data_compare to compare it.
4011 * Removed silc_idlist_find_client_by_hash as it is not needed
4012 anymore. Affected file silcd/idlist.[ch].
4014 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4015 to use internally the SilcHashTable. The new ID Cache is a lot
4016 faster than the old one. Some of the ID Cache interface was also
4017 rewritten and obsolete and stupid functions were removed.
4019 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Added entry_count field to the SilcHashTable to keep the number
4022 of the entries in the table. Implemented the function
4023 silc_hash_table_rehash. Added new function
4024 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4026 Fixed a minor bug in silc_hash_table_free.
4028 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4029 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4030 into the lib/silcutil/silcutil.[ch].
4032 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Implemented a collision resistant hash table into the
4035 lib/silcutil/silchashtable[ch]. See the header and the source
4036 for the SilcHashTable API.
4038 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Merged dotconf version 1.0.2 into lib/dotconf.
4042 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Do not compile anything in lib/silcsim/* if the SIM support
4045 is not enabled. The tree should now compile without problems
4048 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Compiled the SILC under cygwin. Compiled and tested briefly
4051 without problems. More tests needed. The SIMs didn't compile
4054 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4056 * Fixed possible crash in silc_get_username in the
4057 lib/silcutil/silcutil.c.
4059 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Fixed a va_arg in silc/client_ops.c.
4063 * Oops, RC5 routines were named AES and caused some problems
4064 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4066 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added new SilcIDIP structure into the lib/silccore/id.h and
4069 replaced the old `ip' fields from all SILC ID's to that type.
4070 This is a step towards IPv6 support.
4072 The silc_id_get_len takes now the ID as an extra argument.
4073 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4074 both IPv4 and IPv6 based ID's.
4076 The affected files are lib/silccore/id.[ch] and other files
4077 around the tree using these routines.
4079 * Removed the ID length arguments in server from various
4080 silc_server_send_notify_* routines -> they are not needed
4083 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Fixed memory leak in silc_encode_pem_file in the file
4086 lib/silcutil/silcutil.c.
4088 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Check minor version as well in the SKE. Affected files are
4091 silcd/protocol.c and lib/silcclient/protocol.c.
4093 * Added --identifier option to the server so that an identifier
4094 can be when creating the public key for the server. Affected
4095 file is silcd/silcd.c.
4097 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4098 lib/silccrypt/silcpkcs.c.
4100 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Register default ciphers and stuff when using -C option with
4103 the server. Affected file sildc/silcd.c.
4105 * Put back the servers public key filename format, it is better
4106 than the new one. For now, the client keys are saved with the
4107 new filename format. The affected file silc/client_ops.c.
4109 * Implemented the Cipher API for the rest of the ciphers that
4110 did not implement it or implemented it the wrong way.
4112 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Register default ciphers and stuff when using the -S option
4115 in the client. Affected file silc/silc.c. Same also when
4116 creating new key pair with -C option.
4118 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Fixed the silc_verify_public_key client operation function to
4121 save the public keys differently. The fingerprint is now
4122 used as filename and not the hostname. This way also the
4123 client keys are saved uniquely and not with hostnames. The
4124 affected file is silc/client_ops.c.
4126 * Trimmed the silc_hash_fingerprint function to remove extra
4127 whitespaces from the end of the fingerprint. The affected
4128 file is lib/silccrypt/silchash.c.
4132 * Added silc_cipher_register_default function to register all
4133 default ciphers. It can be used when configuration files
4134 does not exist and the application does not want any specific
4135 ciphers in any specific order.
4137 The SilcDList is now used as silc_cipher_list dynamically
4138 allocated cipher list. Removed the static list all together
4139 and now all ciphers must be allocated to the dynamic list.
4140 The silc_cipher_alloc routine was changed to check only the
4143 All silc_cipher_* routines that used to return int returns
4146 The affected files lib/silccrypt/silccrypt.[ch].
4148 * The same thing was done to silc_hash_* as for silc_cipher_*
4149 routines. Affected files lib/silccrypt/silchash.[ch].
4151 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4152 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4153 Added also silc_pkcs_[un]register[_default] functions.
4154 Removed the data_context from the PKCS API.
4156 * Added silc_hmac_register_default function to register default
4157 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4158 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4159 to unregister all hmacs at once.
4161 * Register the default ciphers, hash functions, PKCSs and HMACs
4162 if client's configuration file does not exist. The affected
4165 * The client did not load the hash functions from the SIM
4166 modules at all. Added support for this. Affected file is
4167 silc/clientconfig.c.
4169 * When decoding public key with silc_pkcs_public_key_decode, check
4170 the supported algorithm only if PKCS are registered. Affected
4171 file lib/silccrypt/silcpkcs.c. The same was done with the
4172 silc_pkcs_private_key_decode.
4174 * Fixed the SILC List routines to keep the list always in order.
4175 It used to change the list's order when traversing the list but
4176 not it preserves the order. Affected file lib/trq/silclist.h.
4178 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added the client library to use the SilcSocketConnection's
4181 reference counter (by silc_socket_dup) to prevent the bug that
4182 the socket object may be freed underneath async operation.
4184 * The name resolv library checking fixes in the configure.in.pre.
4187 * Created new version of the protocol drafts for future
4188 development. The -03 drafts are the ones that will be changed
4189 in the trunk now and the -02 will remain as they are.
4191 * Send list of CUMODE notifys to the router when announcing
4192 the channel users to the router. Affected file silcd/server.c.
4193 If the router receiving channel founder CUMODE for a channel
4194 that already has channel founder it will send CUMODE notify
4195 to the sender to remove the channel founder rights from the
4196 announced client. Affected file silcd/packet_receive.c.
4198 * The CUMODE notify may now use Server ID as well as the entity
4199 who changes the mode. Updated protocool specs.
4201 * Updated INSTALL and README files.
4203 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * New web pages in the http://silc.pspt.fi. The pages was
4210 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Implemented the [DenyConnectin] config section in the server.
4213 Added silc_server_config_denied_conn to check whether incoming
4214 connection is denied. Affected file silcd/serverconfig.[ch].
4216 * Do not check the ports when checking the incoming configuration
4217 data if the port is 0, meaning any. Affected file is
4218 silcd/serverconfig.c.
4220 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed buffer overflow in silc_string_compare in the file
4223 lib/silcutil/silcutil.c.
4225 * Fixed double free in silc_server_command_leave in the file
4228 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Fixed the version checking in the server. Affected file is
4233 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Fixed the configuration data fetching when accepting new
4236 connections in the server. Affected file silcd/server.c.
4238 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Added `sender_entry' argument to the function
4241 silc_server_packet_relay_to_channel so that we can check
4242 whether some destination actually belongs to the same route
4243 the sender belongs (ie, we must not resend the packet to the
4244 sender). Affected file silcd/packet_send.[ch].
4246 * Added `servername' field to the SilcClientEntry in the server
4247 to hold the name of the server where client is from. Affected
4248 file is silcd/idlist.h.
4250 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Moved the channel message encrypting in the router betwen
4253 router connections from silc_server_channel_message to the
4254 silc_server_packet_relay_to_channel since we want to check
4255 whether we have anybody channel before encrypting anything.
4256 Affected files silcd/packet_[receive/send].c.
4258 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Fixed the [AdminConnection] server config section to support
4261 multiple entries. Affected file silcd/serverconfig.c.
4263 * Added support into the server to check the validity of the
4264 incoming connection before executing any KE or authentication
4267 * The connection configuration is now saved to the KE and
4268 connection auth protocol contexts and not fetched anymore in
4269 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4271 * The local hosts listenning address and port is also resolved
4272 now when starting the server. We want to have the socket object
4273 to include the real address and port for the listener. Added
4274 new function silc_net_check_local_by_sock into the files
4275 lib/silcutil/silcnet.[ch].
4277 * Fixed a broadcast bug in server -> do not broadcast if we
4280 * Fixed a routing bug. Do not route broadcast packets ever.
4281 Broadcast packets must be processed always and not routed since
4282 they may be destined to some other host than yourself and thus
4283 would get routed without no good reason. Affected file is
4286 * Added function silc_server_config_is_primary_route to check
4287 whether primary router connection has been configured (a router
4288 configuration that we are initiating). If there is not, we
4289 will assume that there is only two routers in the SILC network
4290 and we will use the incoming router connection as our primary
4291 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4293 * Changed the order of the broadcasting. Broadcast _after_ the
4294 packet has been processed not before. Affected file is
4297 * Fixed a [ClientConnection] parsing bug. The port was never
4298 parsed correctly thus resulting to port 0. Affected file
4299 silcd/serverconfig.c.
4301 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4302 argument and did not set the broadcast packet flag. Affected
4303 file silcd/packet_send.c. Fixed same bug in the function
4304 silc_server_send_notify as well.
4306 * If we receive NEW_ID packet for our own ID in the server, ignore
4309 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Removed the nickname from the Private Message Payload.
4314 Updated the code and the protocol specs.
4316 * Updated protocol specs for submitting to the IETF.
4318 * Tweaked the Random Number Generator a bit. Affected file
4319 lib/silccrypt/silcrng.c. Exported a new function
4320 silc_rng_[global]_add_noise which can be used to add more
4323 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Do not parse packets with different timeout when protocol
4326 is active -> may cause problem with rekey. Affected file
4329 * When server receives signoff notify it must not create
4330 new channel key if the client is on any channels since the
4331 sender of the signoff notify will create it.
4333 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Added printing of error messages during SKE protocol from the
4336 failure packet sent by server during SKE. Affected file
4339 * Removed the client's failure_callback handling with timeout
4340 and handle it immediately when received.
4342 * The SKE library returned wrong type in SUCCESS and FAILURE
4343 packets. They must be 32 bit MSB not 16 bit MSB.
4345 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Ok, rewrote the logic of the re-key and now it seems to work.
4348 I tested it on high traffic with frequent re-keys without
4349 problems. Added hmac_receive (and renamed hmac to hmac_send)
4350 in SilcClientConnection in lib/silcclient/client.h and
4351 in SilcIDListData in silcd/idlist.h. Also, removed the
4352 SilcPacketParserContext's cipher and hmac fields as they are
4353 not needed anymore and actually caused some problems when
4354 the ciphers and hmac's changed underneath the packet parser.
4356 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * If re-key protocol is active then process the incoming packets
4359 synchronously since we must assure that icoming packets encrypted
4360 with the old key is processed before the new keys is set to
4361 use. This is true other packets than for REKEY packets.
4362 Affected file silcd/server.c. The same was done to client library
4363 as well, affected file lib/silcclient/client.c.
4365 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4367 * Fixed bug in client and server to accept the force send if
4368 the packet is send from silc_[server/client]_packet_process
4369 function. Otherwise the packets are never delivered, oops.
4371 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Disable force sending of packets when REKEY protocol is active.
4374 We must assure that no packet is sent directly when rekey is
4375 performed. All packets must be sent through packet queue.
4376 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4377 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4378 function is silc_[server/client]_packet_send_real to check
4381 * Replaced the SIM paths from example config files to
4382 /usr/local/modules. Also, make install creates now
4383 /usr/local/silc/logs directory to hold all the SILC server
4386 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Made the configure.in.pre work on Solaris. Patch by salo.
4390 * Made all ciphers compatible with non-x86 machines. Defined
4391 CBC mode macros into lib/silccrypt/ciphers_def.h.
4393 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed the make install.
4397 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * When MAC computation fails the silc_packet_decrypt returned 0
4400 even though it was supposed to return -1. Fixed this. The
4401 affected file is lib/silccore/silcpacket.c.
4403 * Do not replace the config files in /etc/silc (in make install)
4404 if they already exist. Affected file ./Makefile.am.
4406 * Do not send re-key packets immediately but through packet queue.
4407 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4409 * Changed silc_net_check_host_by_sock to return FALSE if the
4410 IP/DNS could not be resolved. Though, it returns the IP address
4411 now even if it could not resolve it (but returns also FALSE).
4412 Affected file lib/silcutil/silcnet.[ch].
4414 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added silc_pkcs_decode_identifier to decode the public key's
4417 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4418 Added also silc_pkcs_free_identifier. Added also new context
4419 SilcPublicKeyIdentifier.
4421 * Added -S option to the silc client. It is used to dump the
4422 contents of the specified public key file.
4424 * Changed the PKCS api to return the public key length when
4425 setting the public key.
4427 * Fixed a fatal bug in the public and private key file loading.
4428 Affected file lib/silccrypt/silcpkcs.c.
4430 * Execute the packet parsing for client with zero (0) timeout
4431 if the protocol is active. Affected file silcd/server.c.
4433 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Made the key generation options to the silcd program. Added
4436 -C option, equivalent to client's option.
4438 * Added new [ServerKeys] config section to the server. It
4439 configures the server's public and private key.
4441 * Defined generic Public Key Payload into the protocol
4442 specification to send specific type of public keys and
4445 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4446 public key or certificate.
4448 * Implemented the GETKEY command to the server and to the
4449 client library and on user interface.
4451 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Made preliminary `make install' work.
4455 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Added SilcServerRekey context into silcd/idlist.h.
4459 * Added the PFS support as defined in the specification to the
4460 SKE protocol. Affected files lib/silcske/*.c.
4462 * Added `ske_group' field to the SilcServerRekey context to hold
4463 the number of the SKE group that is used with PFS in re-key.
4464 Affected file silcd/idlist.h.
4466 * Added PFS re-key support to the server. Affected file is
4469 * Added silc_protocol_cancel to cancel execution of the next
4470 state of the protocol. Affected file is
4471 lib/silccore/silcprotocol.[ch].
4473 * Added the re-key support with and without PFS to the client
4474 library. Re-key is performed once in an hour, by default.
4476 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4477 Added silc_client_rekey_callback and silc_client_rekey_final.
4478 Affected files are lib/silcclient/protocol.[ch] and
4479 lib/silcclient/client.[ch].
4481 * Removed the `hmac_key' and `hmac_key_len' fields from the
4482 SilcClientConnection structure; not needed. Affected file is
4483 lib/silcclient/client.h.
4487 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Do not ask whether user wants to use the negotiated private key
4490 for private messages, just use it. Affected file is
4491 silc/local_command.c.
4493 * Added `send_enc_key' and `enc_key_len' fields to the
4494 SilcIDListData structure since they are needed in the re-key
4495 phase. Affected file is silcd/idlist.[ch].
4497 * Implemented the simple re-key protocol into the server.
4498 Affected files silcd/server.c and silcd/protocol.[ch]. The
4499 re-key will be performed once in an hour, by default.
4501 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4502 Added silc_server_rekey, silc_server_rekey_callback and
4503 silc_server_rekey_final.
4505 * Removed Tunneled flag from the protocol. Updated the code
4506 and the specifications.
4508 * Adde `pfs' field to the SilcIDListData to indicate whether
4509 the PFS is to be performed in the re-key. Affected file is
4512 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4515 int64 of at least the xintXX size. If void * is less that 4
4516 bytes uint32 * will be used. Defined bool as boolean.
4518 * Changed _ALL_ unsigned long and unsigned int to uint32,
4519 unsgined short to uint16 in the source tree.
4521 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4522 not handle clients that has entry->data.registered == FALSE.
4523 They are not in the network anymore. Affected file is
4526 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Implemented the sending of the SERVER_SIGNOFF notify in the
4529 server. Affected file is silcd/server.c.
4531 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4532 Added also silc_notify_payload_encode_args into the
4533 lib/silccore/silcnotify.[ch].
4535 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4536 Affected file silcd/packet_receive.c.
4538 * Implemented the SERVER_SIGNOFF notify handling in the client
4539 library. Affected file lib/silcclient/client_notify.c. Also,
4540 implemnted the printing of the SERVER_SIGNOFF info to the
4541 application. Affected file silc/client_ops.c.
4543 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4544 if the deleting was successful. Affected file silcd/idlist.[ch].
4546 * Added support for public key authentication in the connection
4547 authentication protocol in the client library. Affected file
4548 lib/silcclient/protocol.c.
4550 * Changed the server's silc_idlist_get_clients_by_* interface
4551 to support already allocated array so that new entries may be
4552 added to pre-allocated array. Affected file silcd/idlist.[ch].
4553 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4554 and command replies.
4556 * All command reply functions in the server now calls the
4557 pending command callback even if error occured. This way the
4558 error will be delivered to the client as well. Affected files
4559 silcd/command.c and silcd/command_reply.c.
4561 * Fixed INFO command to return local server's info if no server
4562 was provided. Affected file lib/silcclient/command.c.
4564 * Removed RESTART command for good. Updated the code and the
4567 * Rewrote parts of the task system. It is a bit simpler now.
4568 Removed unsued task priorities. The affected files are
4569 lib/silcutil/silctask.[ch].
4571 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Moved the USERS printing from the library to the application.
4574 Affected files lib/silcclient/command.c and silc/client_ops.c.
4576 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Added channel key re-key support. The re-key is perfomed
4581 only by the router and is done once in an hour. Added `rekey'
4582 field to the SilcChannelEntry in the server. Affected files
4583 silcd/server.c and silcd/idlist.h.
4585 * Added silc_task_unregister_by_context into the file
4586 lib/silcutil/silctask.[ch].
4588 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added SILC_UMODE_GONE mode to indicate when the client is not
4591 present in the SILC network. Added also support to the local
4592 command AWAY that will set this mode. Added support of showing
4593 "xxx is gone" in WHOIS command. The USERS command shows the
4594 gone status as well.
4596 * Fixed setting server and router operator privileges in the
4597 server's UMODE command. Affected file silcd/command.c.
4599 * Merged the SKE KE1 and KE2 payloads into one payload. The
4600 new KE payload is equivalent to the old KE2 payload.
4602 Cleaned up the SKE Start Payload parsing. It now uses the
4603 simple buffer unformatting to do the parsing. A lot faster
4606 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4607 to the SKE that is used to indicate whether both of the SKE
4608 parties should perform authentication. By default only the
4609 responder performs authentication. By setting this flag also
4610 the initiator must do authentication. By default it is unset
4611 since in normal SKE case, client to server connection, only
4612 the responder should do authentication. When doing SKE between
4613 two clients both should perform authentication. Updated the
4614 code and the protocol specs.
4616 * A little fix to IDENTIFY command in the server. Search the
4617 client first by hash not nickname. Affected file is
4620 * Fixed the silc_client_close_connection to support closing
4621 the client to client connections wihtout deleting too much
4622 data. Affected file lib/silcclient/client.c.
4624 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4625 are received if protocol used to be active but is not anymore
4626 the application would crash due to NULL pointer dereference.
4627 Affected files silcd/server.c and lib/silcclient/client.c.
4629 * Added `hash' field to the SilcClientConnection to include
4630 the hash function negotiated in the SKE protocol.
4632 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4633 to set the channel founder authentication data. A client can
4634 claim the founder rights later by providing the authentication
4635 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4636 This way the channel founder can regain the channel founder
4637 privileges even it is left the channel. This works only on
4638 local server and the client must be connected to the same
4639 server to be able to regain the founder rights. Updated the
4640 protocol specs accordingly.
4642 Added support to the CMODE command in the client to set the
4643 founder auth data. Read the README to see how to set it.
4645 Added support to the CUMODE command to claim the founder
4646 rights. Read the README to see how to do it.
4648 Added support for the founder authentication to the Channel
4649 Entry in the server. Affected file silcd/idlist.h.
4651 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4652 server's CMODE command. Affected file silcd/command.c.
4654 * Added the following new functions into lib/silccore/silcauth.[ch]:
4655 silc_auth_get_method and silc_auth_get_data.
4657 * The server now saves the remote hosts public key to the
4658 SilcIDListData pointer. Affected file silcd/protocol.c.
4660 * The normal server now does not remove the channel entry from
4661 the cache if the founder authentication data is set. It used
4662 to remove it if the founder was the last one on the channel on
4663 the server and left the channel. The auth data is saved and
4664 if the channel is re-joined later the old entry is used with
4665 the old auth data. Affected files silcd/command_reply.c and
4668 * Removed the `pkcs' field from the SilcIDListData structure
4669 in the server; it is not used. Affected file silcd/idlist.h.
4671 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Fixed packet processing on slow links. Partial packets were
4674 never re-processed because the incoming data buffer was cleared
4675 by the application. Application must not directly clear the
4676 sock->inbuf, the packet processing routines handle it. Fixed
4677 this in client library and in server.
4679 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Fixed the WHOIS and IDENTIFY send reply function to really
4682 check whether to send list or just one entry. Affected file
4685 * Cleaned up the LEAVE command's channel key distribution. The
4686 affected file silcd/command.c.
4688 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4689 can enforce the channel mode as well. In that case the ID
4690 includes the ID of the server. The code now enforces the
4691 mode change if the router have different mode than the server.
4693 * The notify client operation with CMODE_CHANGE notify can now
4694 return NULL client_entry pointer if the CMODE was not changed
4695 by client. Application must check for this.
4697 * Added <Server ID> argument to INFO command to support server
4698 info fetching by Server ID.
4700 * Added silc_server_announce_get_channel_users to get assembled
4701 packets of channel users of the specified channel. Affected
4702 file silcd/server.[ch].
4704 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4705 was freed underneath the ID Cache.
4707 * Re-announce clients when the server received CHANNEL_CHANGE
4708 notify from the router. Affected file silcd/packet_send.c.
4710 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4713 crashed since it did not handle the fact that there is no cipher
4714 called "3" and didn't check the error condition. Now fixed.
4716 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4717 flag. It can be used to send message requests.
4719 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Implemented the RESTART command in the client.
4723 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4724 notice type messages. Added notice printing to the user
4727 * The channel keys are not re-generated if the channel's mode
4728 is PRIVKEY, ie private key on the channel exists. Affected
4729 files silcd/server.c and silcd/command.c.
4731 * Fixed a little bug in channel message delivery when channel
4732 private keys are set in the server. Affected file is
4733 silcd/packet_send.c.
4735 * Changed the setting on channel->on_channel = TRUE from the
4736 silc_client_save_channel_key to the JOIN command reply. The
4737 key payload is not received if the private channel key is set.
4738 Affected file lib/silcclient/command_reply.c and the
4739 lib/silcclient/client_channel.c.
4741 * When the CMODE_CHANGE notify is sent and the channel private
4742 key mode is removed the channel key must be re-generated in
4743 other cells as well. Added this support for the router in the
4744 silcd/packet_receive.c.
4746 * Added new local command NOTICE to send notice message on
4747 channel. Affected file silc/local_command.[ch].
4749 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Added new local command ME to the client. It is used to send
4752 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4753 some action. Affected file silc/local_command.[ch].
4755 * Changed channel_message and private_message client operations
4756 to deliver the message flags to the application. Added also
4757 the `flags' arguments to the silc_client_send_channel_message
4758 and silc_client_send_private_message functions. Affected file
4761 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Redefined the Private Message Payload to support private message
4764 keys and to support the new private message flags. Updated
4765 the protocol specs. Flags makes it possible to have for example
4766 CTCP style messages.
4768 * Added new type SilcPrivateMessagePayload and defined an API
4769 for it in the lib/silcclient/silcprivate.[ch].
4771 * Tested private message private keys successfully. Tested the
4772 private message key set, unset and list commands with the new
4775 * Redefined the Channel Message Payload to include the channel
4776 message flags (equal with private message flags) to support
4777 for example CTCP style messages.
4779 * Defined some of the message (for channel and private message)
4780 flags. Updated the protocol specs and added the flags to the
4781 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4783 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Added SilcKeyAgreementStatus type to the key agreement routines
4786 to indicate the current status and error if one occured.
4787 The status types are defined in the lib/silcclient/silcapi.h.
4789 * Added new local command KEY that is used to set and unset private
4790 keys for channels, set and unset private keys for private messages
4791 with remote clients and to send key agreement requests and
4792 negotiate the key agreement protocol with remote client. The
4793 key agreement is supported only to negotiate private message keys,
4794 it currently cannot be used to negotiate private keys for channels,
4795 as it is not convenient for that purpose.
4797 * Fixed a minor pending callback setting bug in the function
4798 silc_client_get_client_by_id_resolve, now the function works.
4799 Affected file lib/silcclient/idlist.c.
4801 * Added function silc_net_get_local_port to get local bound
4802 port by socket. Added to lib/silcutil/silcnet.[ch].
4804 * Added `sockets' and `sockets_count' fields to the SilcClient
4805 object. They hold the sockets of the listenning sockets in
4806 the client. Listenning sockets may be for example the key
4807 agreement server. Affected file lib/silcclient/client.[ch].
4808 Added functions the silc_client_add_socket and the
4809 silc_client_del_socket. They are exported to the application
4812 * Added ~./silc/clientkeys to support other client's public keys.
4814 * Renamed verify_server_key client operation to verify_public_key
4815 and added one argument to indicate the type of the connection
4816 (server, client etc.).
4818 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Added silc_server_connection_auth_request to handle the
4821 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4822 silcd/packet_receive.[ch].
4824 * Added silc_server_send_connection_auth_request into the
4825 silcd/packet_send.c to send the connection auth request packet.
4827 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4830 * Fixed the public key authentication in responder side in the
4831 server. The `auth_data' pointer includes the SilcPublicKey
4832 not the path to the public key. Affected file silcd/protocol.c.
4834 * Implemented the public key authentication in the initiator side
4835 in the server. Affected file silcd/protocol.c.
4837 * Removed the [RedirectClient] config section from the server
4838 configuration. Is not needed and I don't want to implement it.
4840 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Cleaned up the CMODE command in the server. It now works
4843 correctly and supports all the modes defined in the protocol.
4844 Affected file is silcd/command.c.
4846 * Added `hmac_name' field to the SilcChannelEntry in the server
4847 to hold the default HMAC of the channel. It can be set when
4848 creating the channel (with JOIN command). Affected files
4851 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4852 type to indicate the change of the current cipher and hmac
4853 on the channel. Client can safely ignore the <cipher> argument
4854 (if it chooses to do so) since the CHANNEL_KEY packet will
4855 force the channel key change anyway. The <hmac> argument is
4856 important since the client is responsible of setting the new
4857 HMAC and the hmac key into use.
4859 * Fixed the CMODE command in the client library as well.
4861 * Tested CMODE command in router environment successfully.
4863 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Show the version of the remote client (or server) when connecting
4866 to the server. It is logged to the log file. Affected file
4867 is silcd/protocol.c.
4869 * Fixed the KILLED notify handling in the client library. The
4870 client must be removed from all channels when receiving the
4873 Also, do not remove the client entry when giving the KILL
4874 command but when the KILLED notify is received.
4876 * Removed silc_idlist_find_client_by_nickname from the server.
4877 Not needed anymore. Affected files silcd/idlist.[ch].
4879 * Implemented the CHANNEL_CHANGE notify type handling to the
4880 server. Affected file silcd/server.c.
4884 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Added silc_server_send_notify_invite to send the INVITE
4887 notify between routers.
4889 * Implemented the INVITE command correctly to the server.
4891 * Implemented the INVITE notify type handling in the server.
4893 * Implemented the INVITE command to the client library and on the
4896 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Added function silc_server_get_client_resolve to find the
4899 client entry by ID from all ID lists and then resolve it
4900 (using WHOIS) if it cannot be found. Affected file is
4903 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Implemented the BAN command to the client library.
4907 * The JOIN command in the server now checks the invite list
4910 * Changed the silc_command_reply_payload_encode_va and the
4911 silc_command_payload_encode_va to support that if argument is
4912 NULL it ignores and checks the next argument. Affected file
4913 lib/silccore/silccommand.c.
4915 * Added silc_server_send_notify_ban to send the BAN notify
4916 type between routers.
4918 * Chaned the silc_notify_payload_encode to support that if
4919 argument is NULL it ignores and checks the next argument.
4920 Affected file lib/silccore/silcnotify.c.
4922 * Tested ban lists in router environment successfully.
4924 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Implemented BAN command to the server, in silcd/command.[ch].
4928 * Removed the BAN and INVITE_LIST modes from the CMODE command
4931 * Added function silc_string_match to regex match two strings.
4932 Affected files lib/silcutil/silcutil.[ch].
4934 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Redefined parts of the SilcChannelEntry in the server to support
4937 the new ban and invite lists.
4939 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Redefined the INVITE command. The same command can be used to
4942 invite individuals to the channel but also to manage the invite
4943 list of the channel (to add to and remove from the invite list).
4944 Updated the protocol specs.
4946 * Added new command SILC_COMMAND_BAN that can be used to manage
4947 the ban list of the channel. Updated the protocol specs.
4949 * Removed the channel modes: the SILC_CMODE_BAN and the
4950 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4951 in the CMODE command. The equivalent features are now available
4952 using INVITE and BAN commands. Updated the protocol specs.
4954 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4955 in the network about change in the current ban list. The notify
4956 type is not used by the client.
4958 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4959 support the invite lists.
4961 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Added new function silc_string_regexify that converts string
4964 including wildcard characters into regex string that can
4965 be used by the GNU regex library. Added into the file
4966 lib/silcutil/silcutil.[ch].
4968 Added silc_string_regex_combine to combine to regex strings
4969 into one so that they can be used as one regex string by
4970 the GNU regex library. Added into the file
4971 lib/silcutil/silcutil.[ch].
4973 Added silc_string_regex_match to match two strings. It returns
4974 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4976 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4978 * Imported GNU regex to the soruce tree into lib/contrib.
4979 Fixed some compiler warning from the regex.c.
4981 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Fixed MOTD command in the server to work in router environment.
4985 * Fixed the MOTD command in the client library to support
4986 the server argument in the command.
4988 * Added `nickname_len' argument to the silc_idlist_add_client
4989 in the server, as the `nickname' argument may be binary data
4992 * Added silc_idlist_get_channels to return all channels from
4995 * Implemented LIST command to the server. Affected file is
4998 * Implemented the LIST command to the client library and on the
5001 * Added [<user count>] argument to the LIST command reply.
5002 With private channels the user count is not shown.
5004 * Updated TODO and README.
5006 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * The client entry's data.registered must be TRUE even with
5009 global client entry on global client list. The data.registered
5010 is used to check whether the client is anymore in the network,
5011 for example with WHOWAS command so it must be valid.
5013 * Fixed the WHOWAS command in the server. It now actually works
5014 in router environment. Added function into silcd/command_reply.c
5015 silc_server_command_reply_whowas_save.
5017 * Added silc_idlist_purge function to the silcd/idlist.c
5018 to periodically purge the ID Cache.
5020 * Fixed INFO command in the server. It works now in router
5021 environment. Added <server name> argument to the INFO command
5022 reply. Updated the protocol specs.
5024 * Fixed minor bug in silc_idcache_purge to not purge if the
5025 expire value is zero.
5027 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5028 they were buggy because of the WHOWAS information.
5030 * Fixed local command MSG to handle the async resolving of
5031 the remote client properly. It used to fail the first MSG.
5032 Affected file silc/local_command.c.
5034 * Added `data_len' field to SilcIDCache context.
5036 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Update TODO. Todo in commands in the server.
5040 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5043 used by routers as broadcast packet to inform other routers
5044 about the changed user mode.
5046 Implemented the notify handling in the server. Affected file is
5047 silcd/packet_receive.c. Added the function
5048 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5050 * Added new generic Channel Payload and deprecated the New Channel
5051 Payload. The New Channel Payload is now the generic Channel
5054 * Added new argument `mode' to the silc_server_send_new_channel
5055 as it is required in the Channel Payload now.
5057 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5058 and created a new and real SilChannelPayload to represent the
5059 new generic Channel Payload. Implemented the encode/decode
5060 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5062 * Added silc_server_get_client_channel_list to return the list
5063 of channels the client has joined for WHOIS command reply.
5064 Affected file silcd/server.[ch].
5066 * Implemented the channel list sending in the WHOIS command reply
5067 in server and in the client.
5069 Implemented the channel list displaying on the user interface
5070 as well. Affected file silc/client_ops.c.
5072 * Added silc_channel_payload_parse_list to parse list of Channel
5073 Payloads. It returns SilcDList list of SilcChannelPayloads.
5074 Client for example can use this function to parse the list of
5075 channels it receives in the WHOIS command reply. The caller
5076 must free the list by calling silc_channel_payload_list_free.
5077 Affected files lib/silccore/silcchannel.[ch].
5079 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5081 * Added one new argument <user mode> to the WHOIS command reply
5082 to return the mode of the user in SILC. Updated the protocol
5085 Implemented it to the server and client.
5087 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Fixed the mode printing on the user interface on joining.
5090 Affected file silc/client_ops.c.
5092 * Implemented the UMODE command and user modes in general to the
5093 client library and to the user interface.
5095 * Implemented the UMODE command to the server.
5097 * The server now sends UNKNOWN_COMMAND error status if client sends
5098 unknown command. Affected file silcd/command.c.
5100 * All server commands now handle the command identifier the right
5101 way when sending the command reply to the client. The client can
5102 use to identify the command replies with the identifier.
5104 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Added silc_server_get_client_route to resolve the route to
5107 the client indicated by the client ID. Affected file is
5110 * Added silc_server_relay_packet as general function to relay
5111 packet to arbitrary destination. This deprecates functions
5112 like _send_private_message_key, _relay_notify etc. Affected
5113 file is silcd/packet_send.[ch].
5115 Removed silc_server_send_key_agreement,
5116 silc_server_send_private_message_key and
5117 silc_server_packet_relay_notify functions from the file
5118 silcd/packet_send.[ch].
5122 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5123 server. Affected file silcd/packet_receive.[ch].
5125 * Implemented the KILL command to the client. Implemented the
5126 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5127 Affected files lib/silcclient/command[_reply].c and
5128 lib/silcclient/client_notify.c. Implemented the KILL notify
5129 printing in the user inteface.
5131 * Fixed a lot silc_parse_nick memory leaks from the client
5132 library in the file lib/silcclient/command.c.
5134 * Changed the silc_server_send_notify_on_channels's `sender'
5135 argument from SilcSocketConnection to SilcClientEntry to
5136 check the sender as entry and not as connection object and not
5137 to send to the client provided as argument. The affected file
5138 is silcd/packet_send.[ch].
5140 * The notify packets that are destined directly to the client used
5141 to not to be processed by the server. Now changed that and the
5142 server processes all notify packets. After relaying the packet
5143 to the client the notify packet is processed in the server.
5145 * The silc_server_free_client_data now checks whether there is
5146 pending outgoing traffic for the client and purges the data to
5147 the network before removing the client entry.
5149 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5152 an client is killed from the SILC Network. Updated the protocol
5155 Added new function silc_server_send_notify_killed to the
5156 silcd/packet_send.[ch].
5158 * Added function silc_server_packet_relay_notify to relay notify
5159 packets that are destined directly to a client. In this case
5160 the server does not process the notify packets but merely relays
5161 it to the client. Affected file silcd/packet_send.[ch].
5163 Added also silc_server_packet_process_relay_notify to check
5164 whereto relay the notify. Affected file is
5165 silcd/packet_receive.[ch].
5167 * Implemented the KILL command to the server.
5171 * Added the backup schema desgined last fall to the protocol
5172 specs for everyone to see. The specification is in the
5173 *-spec-xx.txt draft and the packet type definitions for the
5174 backup routers is in *-pp-xx.txt draft. Thusly, added also
5175 new packet type SILC_PACKET_CELL_ROUTERS.
5177 * A big security problem in the implementation discovered. The
5178 signoff of an client did not cause new channel key generation
5179 which it of course should've done. The channel keys must be
5180 always re-generated when client leaves (or signoffs) the channel.
5181 The silc_server_remove_from_channels funtion now handles
5182 the channel key re-generation.
5184 * Added `sender' argument to the silc_server_send_notify_on_channels
5185 to not to send the client provided as argument. Affected file
5186 silcd/packet_send.[ch].
5188 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Implemented OPER and SILCOPER commands into the server and
5193 * Added silc_auth_verify and silc_auth_verify_data to verify
5194 the authentication directly from the authentication payload.
5195 It supports verifying both passphrase and public key based
5196 authentication. Affected file lib/silccore/silcauth.[ch].
5198 * Added `hash' field to the SilcIDListData structure. It is the
5199 hash negotiated in the SKE protocol. Affected file is
5202 * Slight redesigning of the SilcAuthPayload handling routines.
5203 Do not send SilcPKCS but SilcPublicKey as argument.
5205 * Implemented the public key authentication support to the
5206 serverconfig. The public key is loaded from the provided path
5207 and saved as authentication data to void * pointer. Thus,
5208 changed the unsigned char *auth_data to void *auth_data;
5210 * Fixed SHUTDOWN command to send the reply before the server
5211 is shutdown. :) Affected file silcd/command.c.
5213 * Fixed fatal bug in CONNECT command. The hostname was invalid
5214 memory and server crashed. Affected file silcd/command.c.
5216 * Fixed fatal bug in CLOSE command. The server_entry became
5217 invalid but was referenced later in the command. Affected file
5220 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5222 * Fixed fatal bug in failure packet handling. Server ignored
5223 the failure and thus crashed when it came.
5227 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5229 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5230 that the command may be executed only once in (about) 2 seconds.
5231 The old SILC_CF_LAG flag is same but allows command bursts up
5232 to five before limiting.
5234 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5235 server code. Various commands now includes the CF_LAG_STRICT
5236 flag to disallow any kind of miss-use of the command.
5238 * Fixed the silc_buffer_unformat to not to allocate any data
5239 if the length of the data is zero. It used to allocate the
5240 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5242 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Changed the format of AdminConnection configuration section
5245 in the server. Added username of the admin to the format.
5246 Affected files silcd/serverconfig.[ch].
5248 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5249 to return admin configuration data by host, username and/or
5252 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Implemented WHOWAS command to the server. Added the functions:
5256 silc_server_command_whowas_parse,
5257 silc_server_command_whowas_send_reply,
5258 silc_server_command_whowas_from_client and
5259 silc_server_command_whowas_from_server
5261 * Added <Client ID> argument to the WHOWAS command reply. Updated
5262 the protocol specs accordingly.
5264 * Implemented WHOWAS command and command_reply to the client
5267 Implemented the WHOWAS printing on the user interface.
5269 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added new argument to the WHOWAS command reply, the real name.
5272 It is an optional argument. Updated the protocol specs.
5274 * Added SilcIDCacheDestructor callback that is registered when
5275 the SilcIDCache is allocated. The callback is called when
5276 an cache entry in the ID Cache expires, or is purged from the
5277 cache. Added into lib/silccore/idcache.[ch].
5279 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5280 to destruct the client entries when the cache entry expires.
5281 Other ID Cache's in server and in the client library ignores
5284 * If the ID Cache entry's `expire' field is zero then the entry
5285 never expires. Added boolean `expire' argument to the
5286 silc_idcache_add function in the lib/silccore/idcache.[ch].
5287 If it is TRUE the default expiry value is used.
5289 * Added silc_server_free_client_data_timeout that is registered
5290 when client disconnects. By default for 5 minutes we preserve
5291 the client entry for history - for WHOWAS command.
5293 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Added support to the server to enforce that commands are not
5296 executed more than once in 2 seconds. If server receives
5297 commands from client more frequently, timeout is registered
5298 to process the commands. Affected file silcd/command.c.
5299 Added new function silc_server_command_process_timeout.
5301 * Changed NICK_NOTIFY handling in client library to check that
5302 if the client's nickname was changed, so there is no need to
5303 resolve anything from the server.
5305 * Removed error printing from the WHOIS and IDENTIFY commands.
5306 If error occurs then it is ignored silently in the client library.
5307 The application, however, may map the received error to
5308 human readable error string. The application currently maps
5309 the NO_SUCH_NICKNAME error to string.
5311 * Made the command status message public to the application. Moved
5312 them from lib/silcclient/command_reply.c to
5313 lib/silcclient/command_reply.h. The application can map the
5314 received command status to the string with the
5315 silc_client_command_status_message function.
5317 * Added check to the server to check that client's ID is same
5318 as the Source ID in the packet the client sent. They must
5321 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Added dist-bzip hook to the Makefile.am to make bzip2
5324 compressed distributions.
5326 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Server now enforces the maximum length for the nickname and
5329 the channel as protocol specification dictates. 128 bytes for
5330 nickname and 256 bytes for channel name.
5332 * Moved the WHOIS printing to the application. The client libary
5333 does not print out the WHOIS information anymore, the application
5334 must do it. Renamed silc_client_command_reply_whois_print to
5335 the silc_client_command_reply_whois_save.
5337 The client's idle time is also sent to the application now, and
5338 the idle is shown on screen.
5340 * Added silc_client_command_reply_identify_save to save the
5341 received IDENTIFY entries.
5343 * Do not check for channel private keys in message sending and
5344 reception if the channel does not have the PRIVKEY mode set.
5345 Affected file lib/silclient/client_channel.c.
5347 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5350 just surfaced after chaning the JOIN procedure.
5352 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Added silc_client_get_clients_by_list to get client entries
5355 from Client ID list, that is returned for example by JOIN
5356 and USERS command replies. The application should use this
5357 function for example when JOIN command reply is received to
5358 resolve the clients already on the channel (library does not
5359 do that anymore as USERS command reply is not used in the JOIN
5360 procedure anymore). Affected files lib/silcclient/silcapi.h and
5361 lib/silcclient/idlist.c.
5363 * JOIN command reply and USERS command reply returns now SilcBuffer
5364 pointers instead of unsigned char pointers when returning
5365 the client list and mode list.
5367 * Added <Client ID> argument to the JOIN command reply, mainly
5368 for the server to identify for which client the command was
5369 originally sent. Updated protocol specs accordingly.
5371 * Added SilcDlist private_key pointer to the SilcChannelEntry
5372 in the client to support the channel private keys. Affected
5373 file is lib/silcclient/idlist.h.
5375 * Added SilcChannelPrivateKey argument to the function
5376 silc_client_send_channel_message so that application can choose
5377 to use specific private ke if it wants to. If it is not provided,
5378 the normal channel key is used, unless private keys are set.
5379 In this case the first (key that was added first) is used
5380 as the encryption key.
5382 * Implemented the support for channel private key handling.
5383 Implemented the following functions:
5385 silc_client_add_channel_private_key,
5386 silc_client_del_channel_private_keys,
5387 silc_client_del_channel_private_key,
5388 silc_client_list_channel_private_keys and
5389 silc_client_free_channel_private_keys
5391 Affected file lib/silcclient/client_channel.c.
5393 * Added the support for the private keys in the channel message
5394 sending and encryption and in the message reception and
5395 decryption. Affected funtions are
5396 silc_client_send_channel_message and silc_client_channel_message.
5398 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Added SKE's key verify callback to the client library's
5401 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5403 * Removed the statement that server (or router) must send USERS
5404 command reply when joining to the channel so that the client
5405 knows who are on the channel. Instead, the client list and
5406 client's mode list is now sent in the JOIN command reply to the
5407 client who joined channel. This is better solution.
5409 * Added function silc_server_get_users_on_channel and function
5410 silc_server_save_users_on_channel to the silcd/server.[ch].
5412 * Removed function silc_server_command_send_users from the
5415 * Do not show topic on the client library anymore. The topic is
5416 sent in the command reply notify to the application and the
5417 application must show the topic now.
5419 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Added client searching by nickname hash into the IDENTIFY and
5422 WHOIS commands in the server as they were clearly missing from
5423 them. Affected file is silcd/command.c.
5425 * Fixed a bug in private message receiving in the client library.
5426 The remote ID was freed and it wasn't supposed, now it is
5429 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Minor fix to the channel payload; allocate the data area, as it
5432 needs to be of specific length.
5434 * If the key agreement port is zero then the operating
5435 system will define the bound port. Affected files are
5436 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5438 * Added new function silc_channel_payload_decrypt into the file
5439 lib/silccore/silcchannel.[ch].
5441 * Moved the channel message etc, check from silc_packet_decrypt
5442 to applications. The library calls now a generic
5443 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5444 when the packet is either normal or special. This was done to
5445 allow more wide range of checking that was not allowed when
5446 the code was in library. Now applications can do virtually any
5447 checks to the packet and return to the library the decision how
5448 the packet should be processed. Affected files are
5449 lib/silccore/silcpacket.[ch].
5451 Added silc_server_packet_decrypt_check to the server and
5452 silc_client_packet_decrypt_check to the client library.
5454 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5455 to send with specified source and destination information.
5457 * Channel message delivery between routers was broken after the
5458 channel key distribution was fixed earlier. The channel key
5459 was used be to distributed to other routers as well which is not
5460 allowed by the protocol. Now this is fixed and channel keys
5461 really are cell specific and the channel message delivery between
5462 routers comply with the protocol specification.
5464 * Fixed various commands in server to check also the global list
5465 for the channel entry and not just the local list. The affected
5466 file silcd/command.c.
5468 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Added assert()s to buffer formatting and unformatting routines
5471 to assert (if --enable-debug) when error occurs. Affected
5472 file: lib/silcutil/silcbuffmt.c.
5474 * Changed to auto-reconnect to check whether the remote host is
5475 router and register the re-connect timeout if it is. It used
5476 to check that whether we are normal server, but router must do
5477 auto-reconnect with another router as well. Affected file
5480 * Removed the [<key len>] option from CMODE command as the cipher
5481 name decides the key length, nowadays. See the defined ciphers
5482 from the protocol specification.
5484 * Added [<hmac>] option to the CMODE command to define the HMAC
5485 for the channel. Added SILC_CMODE_HMAC channel mode.
5487 * Added [<hmac>] option for the JOIN command so that user can
5488 select which HMAC is used to compute the MACs of the channel
5491 * Added Hmac field to the Channel Message Payload. The integrity
5492 of plaintext channel messages are now protected by computing
5493 MAC of the message and attaching the MAC to the payload. The
5494 MAC is encrypted. Now, it is clear that this causes some
5495 overhead to the size of the packet but rationale for this is that
5496 now the receiver can verify whether the channel message decrypted
5497 correctly and also when private keys are set for the channel the
5498 receiver can decrypt the packet with several keys and check from
5499 the MAC which key decrypted the message correctly.
5501 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5502 lib/silccrypt/silccipher.[ch].
5504 * Added silc_hash_len to return the digest length into the
5505 lib/silcrypt/silchash.[ch].
5507 * Rewrote parts of Silc Channel Payload interface in the
5508 lib/silccore/silcchannel.[ch]. The encode function now also
5509 encrypts the packet and parse function decrypts it.
5511 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Fixed a minor formatting bug in the SKE's key material processing.
5514 It actually might have processed the keys wrong way resulting
5517 * Redefined the mandatory HMAC algorithms and added new algorithms.
5518 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5519 and hmac-md5 truncated to 96 bits. The mandatory is now
5520 hmac-sha1-96. Rest are optional (including the one that used
5521 to be mandatory). Rationale for this is that the truncated HMAC
5522 length is sufficient from security point of view and can actually
5523 make the attack against the HMAC harder. Also, the truncated
5524 HMAC causes less overhead to the packets. See the RFC2104 for
5527 * Added new [hmac] configuration section. The SKE used to use
5528 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5529 is of course wrong. The official names that must be proposed in
5530 the SKE are the ones defined in the protocol specification
5531 (hmac-sha1-96 for example). The user can configure any hmac
5532 using any hash function configured in the [hash] section. At
5533 least, the mandatory must be configured.
5535 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5537 * Added HMAC list to the SKE proposal list. It has now both
5538 hash algorithm list and HMAC list. This makes the protocol
5539 incompatible with previous versions. The SKE now seems to work
5540 the way it is supposed to work, for the first time actually.
5542 * Defined plain Hash algorithms to the protocol specification.
5545 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Implemented support for key agreement packets into the server.
5548 Added functions silc_server_key_agreement and
5549 silc_server_send_key_agreement. Other than these functions,
5550 server has nothing to do with this packet.
5552 * Added support for private message key packets into the server.
5553 Added functions silc_server_private_message_key and
5554 silc_server_send_private_message_key.
5558 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5559 called in the protocol's final callback instead in the END
5560 protocol state. This makes a little more sense and in the same
5561 time in client we can use the same protocol routines for normal
5562 key exchange and to key agreement packet handling as well.
5564 * Added to both client's and server's KE protocol context the
5565 SilcSKEKeyMaterial pointer to save the key material. We will
5566 bring the key material to the protocol's final callback by doing
5567 this. The final callback must free the key material.
5569 * Added SKE's packet_send callback into client's KE protocol
5570 context so that the caller can choose what packet sending function
5571 is used. This way we can use different packet sending when
5572 doing normal SKE when doing key agreement packet handling (in
5573 the key agreement packet handling we do not want to encrypt
5576 * Implemented the responder side of the key agreement routines
5577 in the client. The client can now bind to specified port and
5578 accept incoming key negotiation. The key material is passed
5579 to the application after the protocol is over.
5581 * Implemented the processing of incoming Key Agreement packet
5582 in the client. Added function silc_client_key_agreement to
5585 * Implemented the intiator side of the key agreement routines
5586 in the client. The client can now initiate key agreement with
5587 another remote client. The key material is passed to the
5588 application after the protocol is over.
5590 * Created client_keyagr.c to include all the key agreement
5593 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5594 SILC_TASK_CALLBACK except that it is not static.
5596 * Created client_notify.c and moved the Notify packet handling
5597 from the client.[ch] into that file.
5599 * Created client_prvmsg.c and moved all private message and
5600 private message key routines from the client.[ch] into that file.
5602 * Create client_channel.c and moved all channel message and
5603 channel private key routines from the client.[ch] into that file.
5605 * Changed silc_client_get_client_by_id_resolve to resolve with
5606 WHOIS command instead of IDENTIFY command, in the file
5607 lib/silclient/idlist.c.
5609 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Implemented the SKE's responder side to the Client library.
5613 * When FAILURE is received to the protocol do not trust it
5614 blindly. Register a timeout to wait whether the remote closes
5615 the connection as it should do it, only after that process the
5616 actual failure. This was changed to both client and server.
5618 * Added client_internal.h to include some of the structures
5619 there instead of client.h in lib/silcclient/.
5621 * Added function silc_task_unregister_by_callback to unregister
5622 timeouts by the callback function.
5624 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Some "Incomplete WHOIS info" errors has been appearing on the
5627 log files. Took away the entry->userinfo check from WHOIS
5628 reply sending. The entry->userinfo is now " " if client did not
5629 provide one. I thought this was fixed earlier but something
5630 is wrong still. Let's see if the error still appears.
5632 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Fixed a minor bug in the login when the channel key is
5635 re-generated in the server. It used to generate the key in
5636 wrong order and thus caused problems in the channel traffic.
5638 * Fixed a minor bug in channel key distsribution after
5639 KICK command. The key was not sent to the router even though
5642 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Added silc_ske_process_key_material_data as generic routine
5645 to process any key material as the SILC protocol dictates. The
5646 function is used by the actual SKE library but can be used by
5647 applications as well. This relates to the private message keys
5648 and the channel private keys since they must be processed the
5649 same way the normal SILC session keys. The protocol dictates
5650 this. Affected files: lib/silcske/silcske.[ch].
5652 Added also silc_ske_free_key_material to free the
5653 SilcSKEKeyMaterial structure.
5655 * Defined silc_cipher_set_key function to set the key for
5656 cipher without using the object's method function. The affected
5657 files: lib/silccrypt/silccipher.[ch].
5659 * Implemented silc silc_client_add_private_message_key,
5660 silc_client_add_private_message_key_ske,
5661 silc_client_del_private_message_key,
5662 silc_client_list_private_message_keys and
5663 silc_client_free_private_message_keys functions in the
5666 Added functions silc_client_send_private_message_key to send
5667 the Private Message Key payload and silc_client_private_message_key
5668 to handle incoming Private Message Key payload.
5670 * Added Cipher field to the Private Message Key payload to set
5671 the cipher to be used. If ignored, the default cipher defined
5672 in the SILC protocol (aes-256-cbc) is used.
5674 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Removed lib/silcclient/ops.h file.
5678 Redefined parts of the SILC Client Library API. Created new
5679 file silcapi.h that deprecates the ops.h file and defines the
5680 published Client Library API. Defined also private message key
5681 API and channel private key API into the file.
5683 This is the file that the application must include from the
5684 SILC Client Library. Other files need not be included by
5685 the application anymore.
5687 * Added new key_agreement client operation callback and also
5688 defined the Key Agreement library API for the application.
5690 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5693 is used by clients to request key negotiation between another
5694 client in the SILC network. If the negotiation is started it
5695 is performed using the SKE protocol. The result of the
5696 negotiation, the secret key material, can be used for example
5697 as private message key.
5699 Implemented the Key Agreement payload into the files
5700 lib/silccore/silauth.[ch].
5702 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Redefined ciphers for the SILC protocol. Added some new ciphers
5705 and defined the key lengths for the algorithms. Changed the
5706 code accordingly. The default key length is now 256 bits.
5708 * Fixed SKE key distribution function silc_ske_process_key_material
5709 when the key length is more than 128 bits. The default key
5710 length in SILC is now 256 bits.
5712 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5713 to indicate unsupported algorithm.
5715 * Renamed rijndael.c to aes.c and all functions as well.
5717 * Fixed a long standing channel key setting bug in client library.
5718 Weird that it has never surfaced before.
5720 * Fixed bug in channel deletion. If the entire channel is removed
5721 then it must also delete the references of the channel entry
5722 from the client's channel list as the client's channel entry and
5723 the channel's client entry share same memory.
5725 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Implemented CONNECT and SHUTDOWN commands in the client.
5729 * Implemented CLOSE command to the client.
5731 * Added the function silc_idlist_find_server_by_name into the
5732 files silcd/idlist.[ch].
5734 Added the function silc_idlist_find_server_by_conn into the
5735 files silcd/idlist.[ch].
5737 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * DIE command was renamed to SHUTDOWN. Updated the both code
5742 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5743 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5745 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5748 * Added function silc_server_create_connection function to create
5749 connection to remote router. My server implementation actually
5750 does not allow router to connect to normal server (it expects
5751 that normal server always initiates the connection to the router)
5752 so the CONNECT command is only good for connecting to another
5755 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5758 or some other client was kicked from the channel.
5760 Implemented the handling of the notify type to both client
5763 Implemented silc_server_send_notify_kicked to send the KICKED
5764 notify. It is used to send it to the server's primary router.
5766 * Implemented the KICK command into server and client.
5768 * Added `query' argument to the silc_idlist_get_client function
5769 to indicate whether to query the client from server or not if
5772 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5773 to indicate that the client is not channel founder.
5777 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Removed the rng context from SilcPacketContext structure and
5780 changed that the packet routine uses the Global RNG API.
5782 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Added support for quit message that client can "leave" on the
5785 channel when it quits the SILC. It is ditributed inside the
5786 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5788 Added silc_server_free_client_data that will take the
5789 signoff message as argument.
5791 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5793 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Updated parts of the protocol specification to keep it up
5798 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5801 payloads in one packet.
5803 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5804 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5805 use now the new List flag.
5807 * Also deprecated the following packet types: REPLACE_ID,
5808 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5810 * Added list support for Notify packet in server.
5812 * Added silc_server_send_notify_channel_change to send the
5813 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5814 the silc_server_send_replace_id.
5816 * Added silc_server_send_notify_nick_change to send the
5817 NICK_CHANGE notify type. Deprecates the function
5818 silc_server_send_replace_id.
5820 * Added silc_server_send_notify_join to send the JOIN notify type.
5821 Deprecates the function silc_server_send_new_channel_user.
5823 * Added silc_server_send_notify_leave to send LEAVE notify type.
5824 Deprecates the function silc_server_send_remove_channel_user.
5826 * Added silc_server_send_notify_cmode and
5827 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5828 types. Deprecates the silc_server_send_set_mode function.
5830 * Added SERVER_SIGNOFF notify type to indicate that server has
5831 quit. This means that all clients on the channel from that
5832 server will drop. This can be also used when netsplit happens.
5834 Deprecated REMOVE_ID packet type since it is not needed anymore
5837 Added silc_server_send_notify_server_signoff to send the
5838 SERVER_SIGNOFF notify type. Deprecates the function
5839 silc_server_send_remove_id.
5841 Added also silc_server_send_notify_signoff to send the
5842 SIGNOFF notify type.
5844 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5845 SILC protocol from this day on. Changed the protocol
5846 specification as well.
5848 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5849 notify type. It is used between routers to notify about
5850 topic changes on a channel.
5852 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5855 * Partly updated the protocol specification to comply with the
5856 changes now made. It is still though a bit outdated.
5858 * The JOIN notify type now takes one extra argument <Channel ID>.
5859 The packet used to be destined to the channel but now the
5860 JOIN type may be sent as list thus it is impossible to
5861 destine it to any specific channel. By adding this argument
5862 it is again possible.
5864 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5866 * Added CREDITS file. The CHANGES and CREDITS file will appear
5867 in the distribution as well.
5869 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5872 types in the server's silcd/packet_receive.c.
5874 * Implemented CMODE and CUMODE to work in router environment.
5876 * Fixed minor encoding and decoding buglet from the
5877 lib/silccore/silcmode.c.
5879 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5882 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5884 * Changed all SilcConfigServer* and silc_config_server* to
5885 SilcServerConfig* and silc_server_config*, respectively.
5888 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Associated the ID (client or server ID) to the Authentication
5891 Payload to avoid any possibility of forging. Updated the
5892 protocol specification and the code accordingly.
5894 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * The RSA key length is now save to the RsaKey context in the
5897 key generation process in lib/silccrypt/rsa.c. The key length
5898 is now used to figure out the maximum size of the block allowed
5899 to be encrypted/signed.
5901 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5902 is equivalent to the silc_mp_mp2bin but does not allocate any
5905 * Changed silc_mp_mp2bin API to take length argument. If it is
5906 non-zero then the buffer is allocated that large. If zero, then
5907 the size is approximated using silc_mp_sizeinbase, which however
5910 * Created Global RNG API which is global RNG that application can
5911 initialize. After initializing, any routine anywhere in the
5912 code (including library) can use RNG without allocating a new
5913 RNG object. This was done to allow this sort of use of the
5914 RNG in code that has no chance to allocate RNG object. All
5915 applications currently allocate this and many routines in the
5916 library use this. Affected file lib/silccrypt/silcrng.[ch].
5918 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5919 it to use the Global RNG API.
5921 * Defined Authentication Payload into protocol specification that
5922 is used during SILC session to authenticate entities. It is
5923 used for example by client to authenticate itself to the server
5924 to obtain server operator privileges.
5926 Implemented this payload into the lib/silccore/silcauth.[ch].
5927 Implemented also routines for public key based authentication
5928 as the new protocol specification dictates.
5930 Moved definitions of different authentication methods from
5931 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5933 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5934 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5935 silc_pkcs_verify_with_hash functions into the file
5936 lib/silccrypt/silcpkcs.[ch].
5938 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * The client entry's userinfo pointer must be always valid.
5941 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5942 will fail since it requires the userinfo. Now, the userinfo
5943 is allocated as "" if actual userinfo does not exist. Actually,
5944 it must exist and it is totally Ok to drop client connections
5945 that does not announce the userinfo. However, we will make
5946 this workaround for now.
5948 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5949 to return the remote port by socket.
5951 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5954 SILC_SERVER_PENDING_EXEC and added an new macro
5955 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5956 data or when error occurs while processing the pending command.
5958 Added new argument `destructor' into silc_server_command_pending
5959 and to the SilcServerCommandPending object. This destructor is
5960 now called after calling the pending callback or if error occurs
5961 immediately. If error occurs the actual pending callback won't
5962 be called at all - only the destructor. The destructor may be
5963 NULL if destructor is not needed.
5965 All this applies for client library code as well. Similar
5966 changes were made there as well for the pending commands.
5968 In the client, the application must now allocate the
5969 SilcClientCommandContext with the silc_client_command_alloc
5972 * Added reference counter to the SilcServerCommandContext. Added
5973 function silc_server_command_alloc and silc_server_command_dup
5976 Same type of functions added to the client library for the same
5979 * Removed the cmd_ident from IDListData away since it is now
5980 global for all connections. It is the command identifier used
5981 in command sending and with pending commands. The affected file
5984 * Added reference counter to the SilcSocketConnection objecet to
5985 indicate the usage count of the object. The object won't be
5986 freed untill the reference counter hits zero. Currently only
5987 server uses this, and client ignores it. The client must be
5988 set to use this too later. The affected files are
5989 lib/silccore/silcsockconn.[ch]. Added also the function
5990 silc_socket_dup to increase the reference counter.
5992 This was mainly added because it is possible that the socket
5993 is removed underneath of pending command or other async
5994 operation. Now it won't be free'd and proper DISCONNECTING
5995 flags, etc. can be set to avoid sending data to connection that
5996 is not valid anymore.
5998 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5999 the connection. After that it sets SILC_SET_DISCONNECTED.
6000 It is, however, possible that the socket data is not still freed.
6001 The silc_server_packet_process now checks that data is not
6002 read or written to connection that is DISCONNECTED. The socket
6003 get's freed when the reference counter hits zero.
6005 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Changed the client operation API: channel_message operation's
6008 `sender' is now the client entry of the sender, not the nickname
6009 and the `channel' is the channel entry, not the channel name.
6011 In the private_message operation the `sender' is now also the
6012 client entry of the sender not the nickname.
6014 Affected file is lib/silcclient/ops.h and all applications
6015 using the client operations.
6017 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Moved the calling of ops->connect() from connect_to_server_final
6020 into receive_new_id functin since that is the point when the
6021 client is actually allowed to send traffic to network. The
6022 affected file is lib/silcclient/client.c.
6024 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6027 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6028 (if needs broadcasting) instead of broadcasting the packets one
6029 by one which would make a burst in the network traffic.
6031 * Added `broadcast' argument to the functions in silcd/server.[ch]
6032 silc_server_create_new_channel[_with_id] to indicate whether
6033 to send New Channel packet to primary router.
6035 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Added new function into the silcd/server.[ch] files:
6038 silc_server_create_new_channel_with_id to create new channel with
6039 already existing Channel ID.
6041 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6042 lib/silccore/silcpacket.h. This packet is used t send list of
6043 Set Mode payloads inside one packet. Server uses this to set
6044 the modes for the channels and clients on those channels, that it
6045 announced to the router when it connected to it. The protocol
6046 specification has been updated accordingly.
6048 * The silc_server_new_channel did not handle the packet coming
6049 from normal server as it normally does not send that. However,
6050 when it announces its channels it does send it. Implemented
6051 the support for that.
6053 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6054 into the file lib/silccore/id.h.
6056 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Fixed memory leaks in the functions silc_idlist_del_client,
6059 silc_idlist_del_channel and silc_idlist_del_server in the file
6060 silcd/idlist.c. All of those leaked like a sieve.
6062 * Fixed some small memory leaks in the client's function
6063 silc_client_notify_by_server.
6065 * Added functions into silcd/server.c: silc_server_announce_clients,
6066 silc_server_announce_channels and silc_server_announce_server.
6067 These functions are used by normal and router server to announce
6068 to its primary router about clients, channels and servers (when
6069 router) that we own. This is done after we've connected to the
6072 These functions effectively implements the following packet types:
6073 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6074 and SILC_PACKET_NEW_ID_LIST.
6076 * Added new functions into the silcd/packet_receive.[ch]:
6077 silc_server_new_id_list, silc_server_new_channel_list and
6078 silc_server_new_channel_user_list to handle the incoming
6079 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6081 * Added support of changing Channel ID in the function
6082 silc_server_replace_id. If the server that announces a channel
6083 to the router already exists in the router (with same name but
6084 with different Channel ID), router is responsible to send
6085 Replace ID packet to the server and force the server to change
6086 the Channel ID to the one router has.
6088 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6089 client that the Channel ID has been changed by the router. The
6090 normal server sends this to the client. Client must start using
6091 the new Channel ID as the channel's ID.
6093 Implemented handling of this new type into lib/silcclient/client.c
6094 into the function silc_client_notify_by_server.
6096 * Added new function silc_idlist_replace_channel_id into the files
6097 silcd/idlist.[ch] to replace the Channel ID.
6099 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Call silc_server_command_identify_check always when processing
6102 the IDENTIFY command in silcd/command.c
6104 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6107 send keepalive packets. The packet can be sent by clients,
6108 servers and routers.
6110 Added function silc_socket_set_heartbeat into the file
6111 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6112 If not set, the heartbeat is not performed. The actual
6113 heartbeat is implemented in the low level socket connection
6114 library. However, application is responsible of actually
6117 Added silc_server_send_heartbeat to send the actual heartbeat
6118 packet into silcd/packet_send.[ch]. Server now performs
6119 keepalive with all connections.
6121 * Added silc_task_get_first function into lib/silcutil/silctask.c
6122 to return the timeout task with shortest timeout. There was a bug
6123 in task unregistration that caused problems. TODO has been
6124 updated to include that task system must be rewritten.
6126 * The client library will now resolve the client information when
6127 receiving JOIN notify from server for client that we know but
6128 have incomplete information.
6130 * Rewrote parts of silc_server_remove_from_channels and
6131 silc_server_remove_from_one_channel as they did not remove the
6132 channel in some circumstances even though they should've.
6134 * Encryption problem encountered in server:
6136 The LEAVE command used to send the Channel Key packet to the
6137 router immediately after generating it. However, the code
6138 had earlier sent Remove Channel user packet but not immediately,
6139 ie. it was put to queue. The order of packets in the router
6140 was that Channel Key packet was first and Remove Channel User
6141 packet was second, even though they were encrypted in the
6142 reverse order. For this reason, MAC check failed. Now, this
6143 is fixed by not sending the Channel Key packet immediately but
6144 putting it to queue. However, this is more fundamental problem:
6145 packets that are in queue should actually not be encrypted
6146 because packets that are sent immediately gets encrypted
6147 actually with wrong IV (and thus MAC check fails). So, packets
6148 that are in queue should be encrypted when they are sent to
6149 the wire and not when they put to the queue.
6151 However, the problem is that the current system has not been
6152 designed to work that way. Instead, the packet is encrypted
6153 as soon as possible and left to the queue. The queue is then
6154 just purged into wire. There won't be any fixes for this
6155 any time soon. So, the current semantic for packet sending
6158 o If you send packet to remote host and do not force the send
6159 (the packet will be in queue) then all subsequent packets to the
6160 same remote host must also be put to the queue. Only after the
6161 queue has been purged is it safe again to force the packet
6164 o If you send all packets immediately then it safe to send
6165 any of subsequent packets through the queue, however, after
6166 the first packet is put to queue then any subsequent packets
6167 must also be put to the queue.
6169 Follow these rules and everything works fine.
6171 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Added new function silc_server_remove_clients_by_server to
6174 remove all client entries from ID list when the server connection
6175 is lost. In this case it is also important to invalidate all
6176 client entires as they hold the invalid server entry. This
6177 fixes fatal bug when server has lost connection and will reconnect
6180 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Made some sanity checks to silc_server_daemonise like to check
6183 whether the requested user and group actually exists.
6185 * Added sanity check to SKE's silc_ske_responder_finish to check
6186 that the public and private key actually is valid.
6188 * Invalidate the client's nickname when receiving Replace ID
6189 packet and the Client ID is being replaced. This means that the
6190 server will query the nickname if someone needs it (client)
6193 * Sort the ID Cache in client library when the ID Cache data
6194 has changed (needs sorting).
6196 * Do not allow for SILC client to create several connections to
6197 several servers. The client does not support windows right now
6198 and generating multiple connections causes weird behaviour.
6200 Irssi-silc client does support windows and can handle several
6201 connections without problems, see: www.irssi.org and SILC plugin.
6203 * Fixed some places where client was added to the IDList. The
6204 rule of thumb is following (in order to get everything right):
6205 If the client is directly connected local client then the
6206 `connection' argument must be set and `router' argument must be
6207 NULL to silc_idlist_add_client function. If the client is not
6208 directly connected client then the `router' argument must
6209 bet set and the `connection' argument must be NULL to the
6210 silc_idlist_add_client function.
6212 * The funtion silc_server_packet_send_local_channel actually did
6213 not check whether the client was locally connected or not. It
6214 does that now. Fixed a bug related to LEAVE command.
6216 * Fixed Remove Channel User payload parsing bug in server's
6217 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6219 * The server's silc_server_save_channel_key now checks also the
6220 global ID list for the channel as it might not be in the local
6221 list. Fixed a bug related to LEAVE command.
6223 * Is this the end of the [<unknown>] buglet that has been lurking
6224 around for a long time? A little for loop fix in server's
6225 silc_server_command_whois_parse that is used by both IDENTIFY
6226 and WHOIS command. At least, this was a clear bug and a cause
6227 of one type of [<unknown>] buglet.
6229 * WHOIS and IDENTIFY commands call the function
6230 silc_server_command_[whois/identify]_check function even if
6231 we are not router server.
6233 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Added --with-gmp configuration option. If set the GMP
6236 is always compiled in the SILC source tree. If not set then
6237 it is checked whether the system has the GMP3 installed. If
6238 it has then the GMP won't be compiled (the system's headers
6239 and library is used), if it doesn't have it then the GMP is
6240 compiled in the SILC source tree.
6242 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Changed RSA private exponent generation to what PKCS #1
6245 suggests. We try to find the smallest possible d by doing
6246 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6247 not security fix but optimization.
6249 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Added new config entry [Identity] to fork the server and run
6252 it as specific user and group. A patch from Bostik.
6254 * Imported Dotconf configuration library into lib/dotconf.
6255 This will be used to create the SILC configuration files later.
6256 It will appear in the distsribution after this commit.
6258 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * A big code auditing weekend happening. Auditing code for
6261 obvious mistakes, bugs and errors. Also, removing any code
6264 Removed files for being obsolete:
6266 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6267 inline in the file lib/silcutil/silcbuffer.h)
6269 o lib/silcutil/silcbufutil.c (the header has inline versions)
6271 Changed code to fix possible error conditions:
6273 o The buffer formatting routines now check that the destination
6274 buffer really has enough space to add the data. This applies for
6275 both buffer formatting and unformatting
6276 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6277 unformatting was changed to accomodate following rules:
6278 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6279 sent to the function while XXX_*STRING will not allocate or copy
6280 the data into the buffer. Instead it sets the pointer from the
6281 buffer into the pointer sent as argument (XXX_*STRING used to
6282 require that the pointer must be allocated already). This change
6283 makes this whole thing a bit more consistent and more optimized
6284 (note that the data returned in the unformatting with XXX_*STRING
6285 must not be freed now). The routines return now -1 on error.
6287 o Tried to find all code that use buffer_format and buffer_unformat
6288 and added return value checking to prevent formatting and
6289 especially unformatting errors and possible subsequent fatal
6292 o Changed ske->x and ske->KEY to mallocated pointers in
6293 lib/silcske/silcske.h. Fixed possible data and memory leak.
6295 o Added return value checking to all *_parse* functions. Fixed
6296 many memory leaks as well.
6298 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6299 so that buffer overflows would not happen. All code now also
6300 checks the return value as it can fail.
6302 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Added reconnection support to server if the normal server looses
6305 its connection to the router (for example if router is rebooted).
6306 The server performs normal reconnection strategy implemented
6307 to the server. Affected file silcd/server.c.
6309 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * Added new packet type SILC_PACKET_SET_MODE that is used to
6312 distribute the information about changed modes (for clients,
6313 channels and clients channel modes) to all routers in the
6314 network. Updated the protocol specification accordingly.
6316 Added functions into silcd/packet_send.c and
6317 silcd/packet_receive.c: silc_server_send_set_mode,
6318 silc_server_set_mode.
6320 Added new files silcmode.[ch] into lib/silccore that implements
6321 the encoding and decoding of Set Mode Payload. Added new type
6322 SilcSetModePayload. Moved the definitions of different modes
6323 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6325 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Oops, a little mistake in server's connection authentication
6328 protocol. The protocol is not ended with FAILURE but with
6329 SUCCESS if the authentication is Ok. :) Affected file is
6332 * Implemented NICK_CHANGE notify handling in server in the file
6333 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6334 the local clients on the channel. After the changing nickname
6335 in router environment snhould work and the [<unknown>] nickname
6336 should appear no more.
6338 The silc_server_replace_id function that receives the Replace ID
6339 payload now sends the NICK_CHANGE notify type also in the file
6340 silcd/packet_receive.c
6342 * Changed WHOIS and IDENTIFY command to support the maximum amount
6343 of arguments defined in protocol specs (3328 arguments). This
6344 fixed a bug that caused problems when there were more than three
6347 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Added extra parameter, command identifier, to the
6350 silc_client_send_command so that explicit command identifier
6353 Changed that ID list routines uses specific command identifier
6354 when sending WHOIS/IDENTIFY requests to the server so that they
6355 can be identified when the reply comes back.
6357 Affected files lib/silcclient/command.[ch],
6358 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6360 * Added `sender' argument to silc_server_packet_send_to_channel
6361 to indicaet the sender who originally sent the packet to us
6362 that we are now re-sending. Ignored if NULL. Affected file
6363 silcd/packet_send.[ch].
6365 * Added some server statistics support in silcd/server_internal.h
6366 SilcServerStatistics structure and around the server code. Also
6367 send some nice statistics information when client is connecting
6370 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Fixed channel ID decoding in server's JOIN command reply in
6373 silcd/command_reply.c
6375 * Fixed braodcasting of replace ID payload to not to send it if
6376 we are standalone server in silcd/packet_receive.c.
6378 * Fixed all channel message sending routines to not to send
6379 packets to clients that has router set, since they are routed
6380 separately in the same function earlier. Affects file
6381 silcd/packet_send.c and all channel packet sending functions.
6383 * In USERS reply, res_argv[i] are not allocated, the table
6384 is allocated. Thus changed that free the table, not its
6387 * In server's whois_check and identify_check if the client is
6388 locally connected do not send any WHOIS commands - they are not
6391 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6393 * Fixed some minor bugs in client when sending WHOIS command. The
6394 arguments was in wrong order.
6396 * Removed statis function add_to_channel from server in
6397 silcd/command.c that was previously used with the joining but
6400 * Tested USERS command in router environment successfully with two
6401 routers, two servers and two clients.
6403 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Reorganized the USERS command and command reply in client library
6406 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6407 When the command is given by user we register a pending command
6408 callback that will reprocess the command after the reply has been
6409 received from the server. When reprocessing the packet we then
6410 display the information. Thus, the USERS information is displayed
6411 now in the command callback instead of in the command reply
6412 callback. The processing of the command is same as previously
6413 when server has sent the command reply in the JOINing process.
6415 * Added to USERS command in silcd/command_reply.c to join the client,
6416 we didn't use to know about, to the channel after we've created
6417 a client entry for it. Also, for clienet we did know already still
6418 check whether it is on the channel or not and add it if not.
6420 * Removed silc_server_command_join_notify as the function and its
6423 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Changed the client's pending command handling to the same as the
6426 server's pending command handling. It is also now possible to
6427 execute command reply functions from other command reply
6428 function as the function callbacks for commands and command
6429 replies are one and same. The pending commands are not static
6430 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6431 in client connection context. Thus, pending commands are server
6432 connection specific as it is convenient.
6434 Changed the function silc_client_command_pending and
6435 silc_client_command_pending_del and added new function
6436 silc_client_command_pending_check. Removed the
6437 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6440 * Added cmd_ident, current command identifier, to the client
6441 connection context in lib/silcclient/client.h to keep track on
6442 command identifiers used in command sending. Client's command reply
6443 function handling now supports the mandatory command identifiers.
6445 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6446 funtions in client to fully support pending command callbacks.
6448 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6449 as one of the arguments to the application in the command reply
6452 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6453 before first releasing SILC but came back. Now it is removed again
6454 and should come back nomore. The FORWARDED flag was used only
6455 by the JOINing procedure by forwarding the command packet to router.
6456 Now, the JOINing procedure has been changed to more generic (due
6457 to various router environment issues) and FORWARDED is not needed
6458 anymore for anything. The protocol specification is yet to be
6461 Now, removed silc_server_packet_forward from server and the flag
6462 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6464 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Renamed NAMES command to USERS command. The NAMES was named that
6467 due to historical reasons. Now it is renamed. Also, rewrote
6468 parts of the USERS command. The nickname list is not sent anymore
6469 by the server. Only Client ID and mode lists are sent in the USERS
6470 command. Changed this also to the protocol specification.
6472 The client now resolves the names and stuff after it receives
6473 the USERS list from the server when joining to the channel.
6475 * WHOIS and IDENTIFY commands has been changed to support multiple
6476 Client ID's per command. One can now search for multiple users
6477 in the network by sending only one WHOIS or IDENTIFY command.
6478 Changed the code and the protocol specifications.
6480 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6481 uses silc_server_command_whois_parse to parse the request. */
6483 * If normal server, do not parse the WHOIS and IDENTIFY requests
6484 before sending it to the router. Saves some time.
6486 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Fixed JOIN command on client library. Wrong number of arguments
6489 used to crash the client.
6491 * Added silc_server_channel_has_global function to check whether
6492 channel has global users or not.
6494 * Added silc_server_channel_has_local function to check whether channel
6495 has locally connected clients on the channel.
6497 * The silc_server_remove_from_one_channel now checks whether the
6498 channel has global users or not after given client was removed from
6499 the channel. It also checks whether the channel has local clients
6500 on the channel anymore. If it does not have then the channel entry
6501 is removed as it is not needed anymore.
6503 * The silc_server_notify now checks on JOIN notify whether the joining
6504 client is one of locally connected or global. If it is global then
6505 the channel has now global users on the channel and that is marked
6506 to the channel entry. Also, it now saves the global client to
6507 global list who is joining and JOINs it to the channel. This is
6508 for normal server, that is.
6510 Changed silc_server_send_notify_on_channel,
6511 silc_server_packet_relay_to_channel and
6512 silc_server_packet_send_to_channel check if we are normal server
6513 and client has router set (ie. global client) do not send the
6514 message to that client, as it is already routed to our router.
6516 * Implemented LEAVE notify type handling in silc_server_notify
6519 * Tested LEAVE command in router environment successfully. Tested
6520 with two routers, two servers and two clients.
6524 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6526 * Implemented SIGNOFF notify type handling in silc_server_notify
6529 * silc_server_remove_id now removes the client entry from all channels
6530 it has joined and thusly sends SIGNOFF notify type.
6532 * Rewrote the NAMES list generation in server by removing two excess
6533 loops. The lists are created now inside one loop.
6535 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * silc_server_remove_channel_user checks now also global list
6538 for channel and client.
6540 * silc_server_new_channel_user checks now both local and global
6541 list for channel and client. Fixed a bug in client id decoding.
6542 Used to decode wrong buffer.
6544 * silc_server_channel_message checks now both local and global
6545 list for channel entry.
6547 * Tested channel joining (hence JOIN) in router environment
6548 successfully. Tested with two routers, two servers and two
6551 * Tested channel message sending in router environment successfully.
6553 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Added silc_server_save_channel_key into server.[ch] to save the
6556 received channel key in Channel Key payload processing. It is
6557 also used in JOIN command reply handling.
6559 Equivalent function silc_client_save_channel_key added into
6560 client.[ch] into client library.
6562 * Changed JOIN command reply to send information whether the channel
6563 was created or not (is existing already) and the channel key
6564 payload. Changed protocol specs accordingly.
6566 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6567 the request was sent by ID and not by nickname. Crashed on
6570 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6573 now correctly save the received data.
6575 * silc_server_free_sock_user_data now notifies routers in the
6576 network about entities leaving the network.
6578 At the same time implemented functions silc_server_remove_id
6579 and silc_server_send_remove_id to receive and send REMOVE_ID
6580 packets. The packet is used to notify routers in the network
6581 about leaving entities. The ID removed will become invalid in
6584 * Added function silc_idlist_del_server into server. Removes and
6585 free's server entry from ID list.
6587 * silc_server_private_message function now checks, if we are router,
6588 that the destination ID really is valid ID, naturally.
6590 * In router when NEW_ID packet is received (for new client) the
6591 hash of the Client ID is saved in the ID Cache but the
6592 client->nickname is set to NULL, instead of putting the hash
6595 IDENTIFY command now also checks that client->nickname must be
6596 valid. If it is not if will request the data from the server who
6597 owns the client. Added new function
6598 silc_server_command_identify_check.
6600 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6601 to set the command to already allocated Command Payload.
6603 * Tested private message sending in router environment with two
6604 routers, two servers and two clients. Fixed minor bugs and now
6607 * Fixed segfault from client's NAMES command. Used to crash if
6610 * Forwarded packets must not be routed even if it is not destined
6611 to the receiver. Changed server code comply with this.
6613 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added `require_reverse_mapping' boolean value to ServerParams
6616 structure. If TRUE (not default) the server will require that
6617 the connecting host has fully qualified domain name.
6619 If the reverse mapping is not required and hostname could not be
6620 found the IP address is used as hostname.
6622 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Implemented version string checking to both client and server.
6625 The check is incomplete currently due to the abnormal version
6626 strings used in development version of SILC.
6628 * Changed all command functions in server to use the new
6631 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Changed char *data to unsigned char *data in ID Cache system to
6634 support binary data as ID Cache data. Changed code to support
6635 binary data in lib/silccore/idcache.c.
6637 * Renamed silc_server_packet_relay_command_reply to
6638 silc_server_command_reply as it is normal packet receiving
6639 function. Rewrote the function to accept command replys for
6640 servers and not only for clients.
6642 * Mark remote router always as registered server if we are connecting
6643 to it. Otherwise, commands sent by the router to us are ignored.
6645 * All ID List find routines now returns the ID Cache Entry pointer
6646 as well if requested.
6648 * WHOIS command works now in router environment, tested with two
6649 routers, two servers and two clients.
6651 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6652 in router environment (as it is almost equivalent to WHOIS) but
6653 hasn't been tested thoroughly. Added new functions:
6655 silc_server_command_identify_parse
6656 silc_server_command_identify_send_reply
6657 silc_server_command_identify_from_client
6658 silc_server_command_identify_from_server
6660 * Disabled route cache adding because adding two different ID's with
6661 same IP replaces the old cache entry thus giving wrong route.
6662 The entry->router->connection is always the fastest route anyway
6663 so route cache may not be needed. Of course, new routes maybe
6664 established after receiving the ID when the entry->router->connection
6665 might not be anymore the most optimal.
6667 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Add route cache for received ID for fast routing.
6671 * Added silc_server_packet_route to route received packet on router
6672 that is not destined to us.
6674 * Renamed silc_server_get_route to silc_server_route_get.
6676 * Added id_string and id_string_len fields into SilcServer to
6677 include encoded ServerID for fast comparing without excess
6678 encoding of the ID's.
6680 * Cleaned up WHOIS command on server side. Added following static
6683 silc_server_command_whois_parse
6684 silc_server_command_whois_check
6685 silc_server_command_whois_send_reply
6686 silc_server_command_whois_from_client
6687 silc_server_command_whois_from_server
6689 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6690 arguments in command replies. All command functions should be
6691 updated to use this macro.
6693 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Minor typo fixes on command reply handling on server.
6697 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Added silc_server_command_add_to_channel internal routine to add
6700 the client to the channel after router has created the channel and
6701 sent command reply to the server.
6703 * Added generic silc_server_send_command to send any command from
6706 * Use static buffer with ID rendering instead of duplicating data.
6708 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Fixed a channel user mode bug when joining to a channel server gave
6711 everybody channel founder rights, oops.
6713 * We mark ourselves as the router of the incoming server connection
6714 if we are router ourselves. This way we can check in some packet
6715 sending functions whether it is locally connected server. For
6716 incoming router connections we put NULL.
6718 * For router sending packets locally means now always sending the
6719 packet cell wide; to local clients and local servers. For normal
6720 server sending packet locally means sending it to only local
6723 * Fixed the JOIN command to really work in router environment. If the
6724 channel is created it is always created by the router. Router is
6725 also responsible of making the initial joining to the channel,
6726 sending JOIN notify to the sending server and distributing
6727 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6728 does not exist server doesn't do anything else but forward the
6729 command to the router which performs everything.
6731 * Added silc_server_send_channel_key function to send the Channel Key
6734 * Added silc_server_create_channel_key to create new channel key. The
6735 channel key is now re-generated everytime someone joins or leaves
6736 a channel, as protocol dictates. Note: channel->key_len is the
6739 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6742 packet_receive.[ch] to separate packet sending and receiving
6743 routines. The server.[ch] now includes everything else including
6744 actual packet processing (writing and reading data) and other
6747 Renamed silc_server_private_message_send_internal to
6748 silc_server_send_private_message. The routine is still though
6749 used only to relay private messages as server does not send
6750 private messages itself.
6752 Renamed silc_server_new_channel to silc_server_create_new_channel
6753 and added new function sicl_server_new_channel that handles the
6754 incoming New Channel packet. Added also new sending function
6755 silc_server_send_new_channel to send New Channel Payload.
6757 * Added new function silc_server_notify to process incoming notify
6758 packet to the server/router. Server may then relay the notify
6759 to clients if needed.
6761 * Added new function silc_server_new_channel_user to process incoming
6762 New Channel User packet. Router will redistribute the packet and
6763 send JOIN notify to its local clients and locally connected servers
6764 if needed. Normal server will send JOIN notify to its local client
6765 on same channel when received this packet. Added also corresponding
6766 sending function silc_server_send_new_channel_user to sent the
6769 * Added boolean route argument to send_notif_to_channel and
6770 packet_send_to_channel functions to attempt to route the packet
6771 if it is TRUE and send only locally if it is FALSE.
6773 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6775 * silc_server_replace_id now broadcasts the received replace ID
6776 packet if it is not broadcast packet already. The router must
6777 broadcast to inform other routers about changed ID.
6779 * Added backpointer to server's router into SilcServer context in
6780 silcd/server_internal.h.
6782 * Fixed silc_server_packet_broadcast to send correct broadcast
6785 * The channel key is now distributed to the local client as soon
6786 as it is received from the router (in router environment) so that
6787 no other packet may be sent for the channel until client has
6790 * silc_server_remove_channel_user now broadcasts the received
6791 Remove Channel User packet if it is not broadcast packet already.
6792 The router must broadcast to inform other routers about removed
6795 * Added users field into SilcPacketContext that is a reference count
6796 of the context. One can increase the reference count by calling
6797 silc_packet_context_dup which is now changed to just increase the
6798 reference count instead of duplicating the data. The reference
6799 count is decresed by calling silc_packet_context_free that will
6800 free the data after the reference count hits zero.
6802 For now on the packet context and everything allocated into it
6803 (including the raw packet from network) must be freed by calling
6804 the new silc_packet_context_free function. Added also new function
6805 silc_packet_context_alloc that must be used now to allocate the
6806 context. This also means that if a routine is asynchronous from
6807 silc_[client/server]_packet_parse_type the packet context must
6808 be duplicated by calling silc_packet_context_dup. Otherwise it
6809 gets free'd after silc_[client/server]_packet_parse_type returns.
6810 Also, one must remember that if packet is duplicated then its
6811 reference count must be decresed by calling the free function as
6812 many times as it was duplicated.
6814 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6815 from both client and server.
6817 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Made joining to a channel working in router environment.
6821 * Cleaned up JOIN command on server side and create function
6822 silc_server_command_join_channel internal routine to make the
6825 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Changed silc_command_pending list to SilcDList. Also, added
6828 `ident' field to SilcServerCommandPending structure to identify
6829 the reply and to call correct callback.
6831 Added silc_server_command_pending_check function to replace the
6832 corresnponding macro. The silc_command_pending list is not
6835 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6836 to set identifier to previously allocated Command Payload. It
6837 is used to set identifier for command when resending Command
6840 * Added silc_command_payload_encode_payload to encode Command
6841 Payload buffer from SilcCommandPayload structure.
6843 * Added silc_argument_payload_encode_payload to encode Argument
6844 payload buffer from SilcArgumentPayload structure.
6846 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Changed WHOIS command to support router connection on server side.
6849 The whois request is always sent to router unless the server is
6850 standalone server. After server has received the reply from the
6851 router will it send the reply to the client.
6853 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6854 broadcast received broadcast packet. The function is used only
6855 by router. The broadcast packet is always sent to the router's
6858 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6859 render given ID to printable string, for log files for example.
6861 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Made basic router to router connections working. At least they
6864 can now connect to each other but nothing really works the way
6865 they are supposed - yet.
6867 * Added new initiator token to RouterConnection configuration
6868 file in silcd/serverconfig.[ch]. It is used to tell whether we
6869 are the initiator to the remote router or whether we'll expect
6870 the other end to connect.
6872 * Moved registering of listener task to silc_server_init, hence
6873 the server starts listenning as soon as it is run, even if it
6874 does not have connections to other routers. Let's see how well
6877 * Changed default connection retry timeouts for more suitable in
6880 * Removed cipher and such arguments from silc_idlist_add_client
6881 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6882 Added new function silc_idlist_add_data to add the keys and stuff
6885 * Added SilcIDListData structure and added it to SilcClientEntry
6886 and SilcServerEntry as their first field in the structure. This
6887 way we can explicitly cast the ID entries to the SilcIDListData
6888 structure and get common data for the entries. In past, we had
6889 to first check what type of connection it is and then cast it to
6890 correct ID entry type. Now, we can directly cast the opaque
6891 pointer to the SilcIDListData (no matter what ID entry it actually
6892 is) and get the data needed.
6894 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6897 in some circumstances even if threre were timeout tasks, though not
6898 IO tasks, but tasks anyway. Now fixed.
6900 * Defined SilcServerConnection structure to hold connection specific
6901 stuff about directly connected servers and routers. The definition
6902 is currently in silcd/server_internal.h. I thought about having
6903 a bit more important role fro this struct but for now it is used
6904 only when connecting to other server (or router actually).
6906 * Added connecting retry support in server when connecting to
6907 router(s). The retry feature implement exponential backoff
6908 algorithm. Also, added SilcServerParams structure to hold default
6909 parameters for server. For now, it include these retry settings
6910 and are hard coded. After server is moded to be as Silc Server
6911 Library this structure will be more important.
6913 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * Changed client librarys channel->clients table to SilcList and
6916 changed code accordingly.
6918 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Changed client's channel table to SilcList and changed code
6921 accordingly. Also changed SilcChannelClientEntry to include back-
6922 pointer to the channel so that client entry can use that structure
6923 as list as well and we have fast cross-reference to the channel.
6924 This change dramatically decreased the complexity of channel
6925 handling with client entry and vice versa (removed one extra
6926 loop when searching for channel entry from many functions).
6928 * Changed server->sim from table to SilcDList and changed code
6931 * NAMES command can now be used from user interface. It will show
6932 the user list on the channel, neatly.
6934 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6935 Code now saves realname of the user if it becomes available.
6937 * Renamed configure.in to configure.in.pre and made ./prepare
6938 script to automatically add correct version string to
6939 configure.in which it creates from configure.in.pre.
6941 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * NAMES command reply now shows users mode with the nickname when
6946 * Moved silc_client_ch[u]mode[_char] functions from
6947 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6948 place sucks, they are utility functions and should be in some
6951 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6953 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6956 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * Added TRQ (efficient deque and list library) into lib/trq. This is
6961 a very good list library that is currently used in the SILC. Defined
6962 SilcList API over the library because I didn't like the API very
6963 much. See lib/trq/silclist.h for the API and examples of how to
6964 use the API. Fixed various places in the code to use the new
6965 SilcList API. The SilcList is meant for lists that has a structure
6966 already defined as a list. It is not suitable to add just some
6967 context to the list (in TRQ, the context is the list actually).
6969 So, I defined SilcDList that can be used for the purpose where
6970 predefined list structure does not exit. This can be used as
6971 such list. Now some context just can be added to the SilcDList.
6972 Currently this list is not used in the SILC just yet, though there
6973 are a lot places where this can replace dynamically allocated
6974 tables and I will fix these places, later, to use SilcDList.
6975 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6976 and use TRQ internally).
6978 Also fixed some annoying warning messages that the original TRQ
6979 code generated. Also minor changes to TRQ's Makefile.in.
6981 * Added support for querying by Client ID to both WHOIS and
6982 IDENTIFY commands into server, as required by the protocol.
6984 * Removed method function pointers from SilcBuffer structure. They
6985 weren't used to anything and just increased the context size for
6986 no good reason. This change also made silc_buffer_alloc and
6987 silc_buffer_free functions inline functions.
6989 * Disabled command flooding detection support until it's fixed so
6990 that it accepts commands in but does not execute them more than once
6993 * Added silc_net_localhost(), to return local hostname, into
6994 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6995 that must be initialized before calling silc_client_init.
6997 * Added new function: silc_server_send_notify_on_channels to send
6998 notify messages to all channels client has joined. It is assured
6999 that the message is sent only once per client.
7001 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7002 lib/silcutil/silcutil.[ch] as silc_format function. The new
7003 function is generic and is used by server as well, not only by
7004 the logging routines.
7006 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7007 the provided version string was not acceptable. Added new function:
7008 silc_ske_check_version into lib/silcske/silcske.h. The function
7009 must be implemented by the application (client or server) and it
7010 does not reside in the SKE library. The function checks the version
7011 string remote end sent.
7013 * Added back pointers (to opaque context and to SilcSocketConnection)
7014 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7016 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7017 duplicate packet context structure.
7019 * Changed `notify' client operation to send same arguments as client
7020 receives from server except for ID's. ID's are mapped to correct
7021 ID entry and that is returned. Also, if channel entry is not sent
7022 by server but the notify is for channel the channel entry is sent
7023 to application (otherwise application doesn't know that it is for
7024 channel (library gets it from packet's Destination ID)).
7026 * Added silc_client_remove_from_channels into client library to
7027 remove a client from all channels it has joined to. Used when
7028 received SIGNOFF notify from server. Added also new function
7029 silc_client_replace_from_channels to replace old ID entry with
7030 new ID entry on all channels. Used when received NICK_CHANGE
7033 * Fixed ID Cache list handling in silc_idlist_get_client in
7034 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7035 to get (or query) client by ID.
7037 * Updated TODO list.
7039 * Added connection authentication status message defined by the
7040 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7041 support for these into the code in client and server side.
7043 * Added generic function silc_client_send_command to send any command
7044 with variable argument list. Application should use this function
7045 to send commands if the command functions provided by the library
7046 does not suite for the application's user interface needs.
7048 * Added new `failure' client operation. Application is notified about
7049 received failure packet if client is executing a protocol. In this
7050 case the protocol's execution has failed.
7052 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7053 is required by the protocol.
7055 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7056 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7059 * Added status flag to SilcSKE object to indicate realtime status
7060 of the SKE protocol.
7062 * Application receives now exactly same command reply arguments as
7063 the library receives from server. However, if ID is received the
7064 corresponding ID entry is returned to the application (eg. Client
7065 ID is mapped to correct SilcClientEntry entry and that is returned).
7066 Changed command_reply client operation due to this change.
7068 * Changed all ID's in commands and in command replys as ID Payloads.
7069 Change affected both client and server side codes.
7071 All ID's sent in SILC network (with execption of ID's in SILC
7072 Packet header) are sent in ID Payload to support variable length
7075 * Server now notifies nick changes and notifies all clients on
7076 the channels about the new nickname (about the new Client ID,
7079 * Implemented CMODE command to change channel modes. Supports all
7080 channel modes defined by the protocol specs except ban and invite
7081 lists. (Also, private channel key mode is supported but support for
7082 setting private channel key in client is missing, thus, this mode
7083 has no effect on client side (except that server requires that the
7084 client uses private channel key and normal channel traffic does not
7087 Also, invite mode works per se, but INVITE command does not work
7088 yet correctly, so you can set channel as invite only channel but
7089 inviting clients to the channel does not work (it is yet to be
7090 thought what's the best way to do it).
7092 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7093 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7094 Implemented CUMODE command to change user's mode on the channel.
7095 Supports all modes defined by the protocol specs.
7097 * Added NAMES command reply to return users modes on the channel.
7099 * Removed unnecessary and slow ciphers from lib/silccrypt.
7101 * Set SO_KEEPALIVE option to connection sockets by default.
7103 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7105 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7106 redefined the Notify Payload into protocol specs.
7108 * Added silc_id_payload_parse_id to get ID directly from raw
7111 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7114 accept searching by Client ID as well.
7116 * Added support for LEAVE and SIGNOFF notify types in client library.
7118 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7119 to parse ID Payload from raw data.
7121 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7123 * Added flags parameter into silc_ske_assemble_security_properties
7124 function in lib/silcske/silcske.[ch].
7126 * Changed notify client operation to fit better for notify messages
7127 sent by server. The notify payload received from server is now
7128 passed to the application (after parsing it to SilcNotifyPayload).
7129 It is application's responsibility to retrieve the arguments
7130 from the payload and show the message the way it wants. The message
7131 sent by server is implementation specific.
7133 * Changed public keys to comply with the protocol specification.
7134 Old public keys are not supported anymore and are not compatible.
7136 * Removed nickname from Channel Payload as the latest draft removed
7137 it. The client must resolve the nickname from the NAMES command
7138 reply received when it joined the channel.
7140 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7142 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Fixed some errors in protocol specification drafts.
7146 * Created lib/silccore/silcnotify.c to implement Notify Payload
7147 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7148 generic payloads described by protocol specifications. The file
7149 includes implementations for ID Payload and Argument Payload.
7151 * Changed Command Payload implementation to use the new Argument
7152 Payload. Changed command_xxxx_payload to command_payload_xxxx
7153 to comply with SILC coding conventions.
7155 * Added suppport for Argument Payload handling in Notify Payload
7156 implementation as protocol requires it. Added the new support
7157 into server and client lib as well.
7159 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Added support for multiple nicknames on same channel. [n] is
7162 added locally to the nickname if there are more than one same
7163 nicknames on the channel.
7165 * Server now sends all nicknames that matched WHOIS request.
7166 Client also shows the list received from server.
7168 * Added TOPIC command to client side. User can now set and show
7169 current topic on channel.
7171 * Added MOTD command to client and server. Also, server sends the
7172 motd when client connects to the server.
7174 * Changed version strings to comply ISO 8601.
7176 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Fixed protocol error handling in client library. It should now
7179 cope even if the SKE fails for some reason.
7181 * Made new protocol specification drafts for submitting to IETF.
7183 * Implemented TOPIC command to server in silcd/command.c.
7185 * Added two new notify types into lib/silccore/silcnotify.h:
7186 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7187 notify nickname change and topic setting/change on a channel.
7189 * API change of command_reply operation in client library. The
7190 application gets now the status type received from server as well.
7192 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7196 * Cras fixed and optimized the packet handling even further and
7197 it should work now. Minor change to the prototype of function
7198 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7200 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Added new function into lib/silcutil/silcschedule.[ch]:
7203 silc_schedule_with_fd to select() a specified fd. The function
7204 returns after timeout expires or data arrives or goes. The
7205 function is used by packet routines to wait that all data is
7206 received from network.
7208 * Fixed data reading from network in lib/silccore/silcpacket.c.
7209 The code now assures that all data is read from the fd and then
7210 continues packet processing. This was a bug fix since the code
7211 used to drop some data in some circumstances.
7213 * Added new function into lib/silcclient/client.[ch]:
7214 silc_client_start_key_exchange to start key exchange after
7215 connection has been established to server. The code internally
7216 now uses this funtion but its main purpose was to provide it
7217 for applications that perform their own connecting. After
7218 application has created a connection it merely calls this
7219 function to start the key exchange between client and server.
7220 The library takes care of everything else after that.
7222 Updated also lib/silcclient/README to explain the usage of
7225 * Do not send to application information that connection has
7226 been established. Application gets notified it by connect
7229 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Applied cras's patch to add silc_schedule_one function. The
7232 function runs scheduler once and returns.
7234 * Fixed the scheduler after cras messed it up. The timeout
7235 handling works now as it's supposed to work.
7237 * Added into lib/silccore/ silcnotify.h to include notify
7238 message types support. Changed silc_server_send_notify*
7239 functions, in server.[ch], to support those new notify types.
7240 Added the support for the notify types into client library,
7241 as well. Added new notify client operation into ops.h in
7244 * Changed silc_server_packet_send_to_channel to send normal
7245 packets instead of just channel message packets. The function
7246 is now used to send the notify packets to channels. It is not
7247 used to send channel message packets anymore, as server never
7250 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7251 va_arg()s as it seems to require it nowadays. I guess, if SILC
7252 is compiled with older va_arg() the new code should work anyway.
7254 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Splitted core library. Core library (lib/silccore) includes
7257 now only SILC protocol specific core (and common) components.
7258 Created new utility library (lib/silcutil) that includes more
7259 generic purpose stuff. The stuff for util library was taken
7260 from the old core library. This was minor and easy split.
7262 * Created SILC Client Library (lib/silcclient) that includes
7263 implementation of the SILC client without user interface. This
7264 was major move from silc/ directory. The code has been changed
7265 so that it is transparent towards the user interface. The
7266 silc/ directory includes now the same user interface as before
7267 and it uses the new client library. Read lib/silcclient/README.
7268 Basicly, the client library performs everything else related
7269 to SILC except user interface handling. Also, configuration
7270 files are considered to be part of user interface and library
7271 does not handle them.
7273 This change also changed a lot of structures, function naming etc.
7274 Most important change was that SilcClientWindow object was
7275 renamed to SilcClientConnection in the client library. Created
7276 also new file lib/silcclient/ops.h. Also added new files
7277 silc/local_command.[ch] and silc/client_ops.[ch].
7279 All these changes were made to make it easier for user interface
7280 designers to create what ever user interface for the SILC client
7283 It is also expected that the server will be moved to lib
7284 directory as well and SILC Server Library will be created;
7285 sometimes in the future.
7287 * Removed Local commands from lib/silccore/silccommand.h as
7288 they are application specific and new client library does not
7289 handle any of those anymore.
7291 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7292 old client implementation in silc/.
7294 * Added support for callback functions in SILC_LOG_* macros.
7295 Application can now set its own callbacks that will be called
7296 instead of using the default functions that will always print
7297 the debug messages to stderr (or stdout). Also, debugging can
7298 now be disabled by setting silc_debug to FALSE and re-enabled by
7299 setting it to TRUE. Note, that logging will still work even
7300 if debugging is disabled.
7302 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7303 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7304 silc_log_reset_debug_callbacks.
7306 * To enable debugging in silc client one must give now -d
7307 option on command line.
7309 * Changed silc_schedule_init to automatically allocate task queues
7310 if they are not allocated before calling it.
7312 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Added GMP 3.1 into math library.
7316 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7318 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7319 a channel in SILC network. The packet is used by servers and
7320 routers to notify other routers that user has left a channel.
7321 This little feature was missing until now. Added the feature
7322 to protocol specification as well.
7324 Added functions: silc_server_send_remove_channel_user and
7325 silc_server_remove_channel_user into server.[ch].
7327 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7328 lib/silccore/silcpacket.h. However, they are not implemented
7331 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Fixed joining to a channel and sending channel messages
7334 between server and router. The channel message sending should
7335 now work inside a cell.
7337 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Fixed the private message sending between server and router.
7340 The private message sending should now work inside a cell.
7342 * Added silc_server_replace_id into server.[ch] to replace
7343 existing ID in the SILC network.
7345 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7346 and silc_idlist_replace_server_id into idlist.[ch] in server.
7348 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Fixed the server to server connections. Server can again now
7351 connect to router. Router to router connections probably does
7354 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Added dynamic protocol registering support. Now protocols can
7357 registered and unregistered on the fly. Patch by cras.
7359 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Added lib/contrib directory to hold routines that some platforms
7362 don't have but are needed by SILC.
7364 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7365 into lin/contrib to provide getopt() and getopt_long() for
7366 those who don't have it.
7368 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Added AWAY command to client. When away message is set and
7371 client receives a private message packet the client automatically
7372 replies to the sender with the away message.
7374 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7375 bug seemed to be the cause of recent problems when compiling
7378 * Added version detection support to SKE protocol specification
7379 and added the new changes to the SKE implementation as well.
7380 There were other minor changes in the SKE protocol as well.
7382 Many changes in lib/silcske/silcske.[ch] and in
7383 lib/silcske/payload.[ch].
7385 * Added ^U functionality, clear input line. Patch from cras.
7387 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Mainly small bugfixes on core library. Fixed some debugging
7390 logging and buffer overflow in silclog.c.
7392 * Updated config.sub and config.guess on the distribution tree.
7394 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * Added command lagging support in server. Client may execute
7397 commands now only once in two seconds.
7399 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Optimized packet reception. MAC computation and checking is now
7402 also more optimized. A lot previously duplicated code is now
7403 used as generic by both client and server.
7405 * Fixed key pair generation in clientutil.c
7407 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7409 * Added into lib/silccore/silcbufutil.[ch] new function;
7410 silc_buffer_realloc.
7412 * Moved generic packet sending/encryption functions to
7413 lib/silccore/silcpacket.[ch] from client and server. Some
7414 rewriting of the functions.
7416 * Moved all generic packet reception/decryption functions to
7417 lib/silccore/silcpacket.[ch] from client and server. The
7418 packet processing is now much cleaner in both client and server.
7419 These were major changes in both client and server.
7421 * Created many common functions in server to do packet sending.
7422 Previously code were duplicated a lot, this has been removed
7425 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * Rewrote major parts of the ID cache system. Don't know
7428 whether it is better now or not but at least the API is more
7431 * Major rewrite on ID cache stuff on client because of the ID
7432 cache API changes. Added idlist.c to client.
7434 * Also major rewrite on ID cache stuff on server as well.
7435 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7436 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7437 in hand, instead they are all put into the ID cache system now.
7438 All server_idlist_* routines uses ID cache now instead of
7439 traversing its own lists (those lists does not exist anymore).
7440 SilcIDList though still exists. Also, SilcXXXEntry's are
7443 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7445 * Finally made the SKE implementation compliant to the protocol
7446 specification. All mp integers are now binary encoded as
7447 opposed being HEX encoded.
7449 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7452 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7453 functions: silc_[encode/decode]_pem. Also added function
7454 silc_encode_pem_file to PEM encode with newlines ('\n') for
7457 * SILC public keys are now encoded either PEM or binary. Same
7458 option is for private keys as well. By default private keys
7459 are binary encoded and public keys PEM encoded. Silly HEX
7460 encoding were removed.
7462 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7463 function to create fingerprints.
7465 * Fixed a bug in SHA1; does not change the original data anymore.
7467 * Partly implemented INFO command on client and server side.
7468 Fixed CLEAR command. Changes to SERVER command; show current
7469 server(s) when giving command without arguments. Added
7470 VERSION command to client.
7472 * Added check to server that unregistered connections cannot
7473 execute commands (unless it is specificly allowed).
7475 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Fixed screen refresh.
7479 * Fixed channel joining bug from client. On some circumstances
7480 client tried to join to a channel it had already joined.
7482 * Added public key verification process into client's protocol.c.
7483 The client now verifies the public key from user and saves
7484 it into ~./silc/serverkeys/ directory.
7486 Added into: clientutil.[ch]: silc_client_verify_server_key.
7488 * Changed SKE protocol's silc_ske_initiator_finish function
7489 to accept callback function that verifies the received public
7490 key. Removed old silc_ske_verify_public_key function.
7492 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7494 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7495 silc_pkcs_private_key[_data]_set.
7497 * Made the password and public authentication more cleaner in
7498 server's protocol.c.
7500 * Removed historic and obsolete protocol `channel_auth' from
7501 both client and server.
7503 * Removed wrong way of sending command status messages from
7504 server to client in server's command.c. The old way violated
7505 protocol specification.
7507 Changes to silccore/silccommand.[ch]: removed
7508 silc_command_encode_status_payload -> not needed anymore,
7509 changed silc_command_encode_payload_va to accept extra
7510 argument on variable argument list. The argument type must
7511 now be provided to the function. Also, added new function:
7512 silc_command_encode_reply_payload_va which is same as
7513 normal command_encode_payload_va except command status type
7514 is provided as extra argument.
7516 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
