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

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

618 is changed and +k mode is set in the channel. Affected file
619 irssi/src/silc/core/silc-channels.c.
621 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
622 SILC_LOG_WARNING to give out Warning and not Error. Affected
623 file lib/silcutil/silclog.c.
625 * Fixed the channel message payload decryption in the function
626 silc_channel_message_payload_decrypt to not modify the original
627 buffer before it is verified that the message decrypted
628 correctly. Otherwise, next time it is called with correct
629 channel key it won't encrypt since the payload is corrupted.
630 Affected file lib/silccore/silcchannel.c.
632 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
634 * Do not constantly resize the window. A fix patch by cras.
635 Affected file irssi/src/fe-text/screen.c.
637 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
640 Affected file lib/silcutil/silcnet.c.
642 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
644 * Fixed a bug in hash table internal routine for traversing
645 the table with foreach callback. The current entry may
646 become invalid in the callback but it was referenced after
647 the callback returned.
649 Do not allow auto rehashing of hash table during the
650 silc_hash_table_foreach operation, for same reasons as it is
651 not allowed for SilcHashTableList. Affected files are
652 lib/silcutil/silchashtable.[ch].
654 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Defined DLLAPI into silcincludes.h and silcwin32.h for
657 Win32 DLL. extern's in header files are now declared with
660 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
662 * Fixed private message handling. It used some old code that
663 caused the client to crash. Affecte file is
664 lib/silcclient/client_prvmsg.c.
666 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * Added function silc_client_add_channel,
669 silc_client_replace_channel_id, and removed functions
670 silc_client_new_channel_id and silc_idlist_get_channel_by_id
673 * Added cross reference of the joined channels to the
674 SilcClientEntry, and changed the SilcChannelEntry's
675 users list to SilcHashTable. The affected files are
676 lib/silcclient/idlist.[ch].
678 * Fixed a bug in hash table tarversing. While the hash table
679 is traversed with SilcHashTableList the table must not be
680 rehashed. It is now guaranteed that auto rehashable tables
681 are not rehashed while tarversing the list. Also defined that
682 silc_hash_table_rehash must not be called while tarversing
683 the table. Added function silc_hash_table_list_reset that must
684 be called after the tarversing is over. The affected files are
685 lib/silcutil/silchashtable.[ch].
687 * Changed all hash table traversing to call the new
688 silc_hash_table_list_reset in server and in client library.
690 * Added function silc_client_on_channel to return the
691 SilcChannelUser entry if the specified client entry is joined
692 on the specified channel. This is exported to application as
693 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
695 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
697 * Fixed founder regaining problem with JOIN command on normal
698 server. The notify for mode change must be sent always and
699 not only if !cmd->pending. Affected file silcd/command.c.
701 * Fixed the WHOWAS command's reply sending to support the
702 lists correctly. Affected file silcd/command.c.
704 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * When sending JOIN command to router for processing the
707 sender's old command identifier was not saved back to the
708 sender's command context, fixed now. The affected file is
711 * Create the key in JOIN command of the router did not return
712 the channel key, added check for this. Affected file is
715 * Fixed a channel ID update bug in JOIN command reply. Do
716 not directly upgrade the ID but call the function
717 silc_idlist_replace_channel_id if the ID was changed.
718 Affected file silcd/command_reply.c.
720 * Fixed memory leaks from command calling if it would fail.
721 Affected file silcd/command.c.
723 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
725 * Applied patches from cras:
727 Memory leak fixes around libaries, irssi window resize fix,
728 new silclist.h and silcdlist.h, all extern inline changed to
731 * Removed dotconf from lib/dotconf, not needed anymore.
733 * Removed TRQ from lib/trq, not needed anymore.
735 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
736 with server connections. Later this will be configurable
737 in config file after new config file is done. Affected file
740 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
742 * Fixed a crash in server related to channel announcements.
743 Affected file silcd/server.c.
745 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
747 * Fixed memory leaks in silc_server_create_new_channel*
748 functions. Affected file silcd/server.c.
750 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
751 which ID was changed. This way the router will send the
752 user list for the channel again, and server won't be in
753 desync in some rare circumstances. Affected file is
754 silcd/packet_receive.c.
756 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
758 * Check for NULL socket pointer in the function
759 silc_server_packet_send_to_channel_real. Affected file
762 * Fixed the BAN notify handling to correctly remove ban
763 list. Affected file silcd/packet_receive.c.
765 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
767 * Fixed some header addition to Toolkit distribution in
768 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
770 * Added lib/silcclient/client_ops_example.h as an template
771 file for application programmers to quickly start using
772 the SilcClientOperation functions in their application.
773 Updated the lib/silcclient/README as well to tell about this
774 nice file made available.
776 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
778 * Call silc_server_remove_from_channels when removing client
779 entry when NO_SUCH_CLIENT_ID was received. Affected file
780 is silcd/command_reply.c.
782 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
784 * Added server & router operator statistics updating. Affected
785 file silcd/packet_receive.c and silcd/command.c.
787 * Fixed the SERVER_SIGNOFF notify handling on normal server
788 not to save the history information for clients. Same was
789 fixed earlier in remove_clients_by_server function, but not
790 here. Affected file silcd/packet_receive.c.
792 * Raised the default connection-retry count from 4 to 7 in
793 server. Affected file silcd/server.h.
795 * Cancel any possible reconnect timeouts when we start the
796 key exchange. Affected file silcd/server.c.
798 * Do not reconnect on connection failure when SCONNECT was
799 given. Affected files silcd/server.[ch].
801 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
805 * Fixed the NICK command to always give the unformatted
806 nickname to the one giving the NICK command. If unformatted
807 nickname is cached already it will be formatted and the
808 local entry will always get the unformatted nickname.
809 Affected file lib/silcclient/idlist.c.
811 * Fixed some double frees from client library commands.
812 Affected file is lib/silcclient/command.c.
814 * Fixed CUMODE command in server to assure that no one can
815 change founder's mode than the founder itself, there was a
816 little bug. Affected file silcd/command.c.
818 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
820 * Removed the SilcClientCommandDestructor from the client
821 libary, it is not needed anymore. Affected files are
822 lib/silcclient/silcapi.h, command[_reply].[ch],
823 client_notify, idlist.c.
825 * Fixed GETKEY command to first resolve client, and then
826 resolve the server only if the client was not found, instead
827 of resolving both at the same time. Affected file is
828 lib/silcclient/command.c.
830 * Added silc_client_start_key_exchange_cb and lookup the
831 remote hostname and IP address before starting the key
832 exchange with server. The affected file is
833 lib/silcclient/client.c.
835 * The server's public key is now saved using the IP address
836 of the server and not the servername for the filename.
837 The hostname public key filename is checked as an fall back
838 method if the IP address based filename is not found.
840 Fixed the GETKEY command to save the fetched server key
843 Print the remote server's hostname now when new key is
844 received during connection process. Affected file is
845 irssi/src/silc/core/client_ops.c.
847 * Return always our own public key to the client if it asks
848 for it with GETKEY command. Affected file silcd/command.c.
850 * Removed the use_auto_addr variable from default config
851 file since it was in wrong section. Affected file is
854 * Fixed TOPIC_CHANGE notification to not route it when it
855 was sent using silc_server_send_notify_to_channel function.
856 Affected file silcd/command.c.
858 * Fixed silc_server_send_notify_kicked to send the kicker's
859 Client ID also, it was missing. Affected files are
860 silcd/command.c, silcd/packet_send.[ch].
862 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
864 * Do not save client history information in SERVER_SIGNOFF.
865 Fixes the bug in normal server that it does not detect
866 the client becoming valid after the server becomes back
867 online. Affected file silcd/server_util.c.
869 * Added `sock_error' field into the SilcSocketConnection
870 context. When error occurs during socket operation (read
871 or write) the error is saved. Added also new function
872 silc_socket_get_error to return human readable socket error
873 message. Affected files are lib/silcutil/silcsockconn.[ch],
874 lib/silcutil/unix/silcunixsockconn.c, and
875 lib/silcutil/win32/silcwin32sockconn.c.
877 * The server now prints the socket error message in the
878 signoff for client. Affected file silcd/server.c.
880 * Fixed the `created' channel information sending from router
881 to server in JOIN command. Checks now whether the channel
882 really was created or not and set it according that.
884 Fixed the JOIN command to use the client entry's current
885 ID during the joining procedure instead of the one it sent
886 in the command (it is checked though), since it can change
887 between the packet processing and command processing, and
888 would just case unnecessary pain in the client end. Affected
889 file silcd/command.c.
891 * Fixed a channel key payload sending to use correct channel
892 ID when the server was forced to change the channel's ID by
893 router. Router sent the key payload with the old Channel ID.
894 Affected file silcd/packet_receive.c.
896 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
898 * Call silc_server_save_channel_key only if the key payload
899 was provided in the JOIN command's command reply. Affected
900 file silcd/command_reply.c.
902 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
904 * Fixed silc_mp_sizeinbase to return the value correctly with
905 MPI. Affected file lib/silcmath/mp_mpi.c.
907 * Fixed the stop_server signal to correctly stop the scheduler
908 and gracefully stop the server when SIGTERM or SIGINT signals
909 are received. Affected file silcd/silcd.c.
911 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
913 * Simple handling of TERM and HUP signals. Also added some log
914 flushing call around. Affected file is
917 * Fixed small bugs in silclog.c. Now buffering output will take
918 effect after 10 seconds since startup: This will ensure that
919 no important startup messages are lost. Also output redirection
920 will preserve original format ([Date] [Type] message).
921 Affected file is lib/silcutil/silclog.c.
923 * Added two options to the config file, in the logging section:
924 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
925 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
927 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
929 * Do not print the warning about log files not being initialized
930 more than once to avoid excess logging. Affected file is
931 lib/silcutil/silclog.c.
933 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
934 the SIM copying in make install in Makefile.am.pre.
936 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
938 * Rewritten silclog APIs. Globally interesting changes follows:
939 silc_log_set_files() changed to silc_log_set_file().
940 silc_log_set_callbacks() changed to silc_log_set_callback().
941 ROBOdoc documented silclog header file.
942 SilcLogCb now returns bool to wether inihibit the default
943 handler or not (to keep the old behaviour return always TRUE).
944 The new APIs should also fix the problem of the
945 silcd_error.log file that was written in the current directory.
948 Log files streams will remain opened after silc_log_set_file()
949 call, means less CPU usage notably on high traffic servers.
950 File streams are now full buffered, and flushed to the disk
951 every 5 minutes, lesses HD activity and CPU usage.
952 Messages can be redirected, allowing admins to configure
953 one single logfile for all server messages.
954 the silc_log_quick global variable to activate fast-logging.
955 Affected files lib/silcutil/silclog.[ch]
957 * Changed some code to conform new silclog APIs. Affected
958 files are doc/example_silcd.conf.in, silcd/server.c
959 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
962 * Fixed a memory leak that could occur in some situations.
963 Affected file silcd/serverconfig.c.
965 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
967 * Added the silc_client_del_client to remove the client from
968 all channels as well. Affected file lib/silcclient/idlist.c.
970 * Fixed the client library to correctly remove the client
971 from all channels when the client entry is being destroyed.
972 Affected file lib/silcclient/client_notify.c, command.c.
974 * Added auto-nicking support to the client library. If the
975 applicatio now sets client->nickname it will be sent to the
976 server after connecting by the library. This way for example
977 SILCNICK (or IRCNICK) environment variables will have effect
978 and always change the nickname automatically to whatever
979 it is wanted. Affected file lib/silcclient/client.[ch].
981 * Renamed silc_server_command_bad_chars to the
982 silc_server_name_bad_chars and moved it to the
983 silcd/server_util.[ch]. Added also new function
984 silc_server_name_modify_bad to return nickname that
985 includes bad characters as new nickname without those
986 bad characters. This check and modify is now used in
987 silc_server_new_client when the username is initially set
988 as nickname, so it must be checked to be valid nickname.
989 Affected file silcd/packet_receive.c.
991 * The nickname length is now taken from the packet for real
992 and not trusted to strlen() since it clearly can return
993 wrong length for nickname including bad characters. This
994 also applies to channel names. Affected file silcd/command.c.
996 * Removed the lib/silcsilm/modules directory. Modules are now
997 compiled into the lib/silcsim. Fixed the copying of the
998 modules to follow symbolic links in Makefile.am.pre.
1000 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1002 * Fixed silc_string_regexify list creation. Fixes bugs with
1003 BAN and INVITE commands in server. The affected file is
1004 lib/silcutil/unix/silcunixutil.c.
1006 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Removed the command destructor entirely from the server's
1009 command and command reply routines. It is not needed, and
1010 its usage was buggy and caused crashes. Affected files are
1011 silcd/command[_reply].[ch].
1013 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Cancel protocol and NULL sock->protocol if timeout
1016 occurred during protocol. Affected file silcd/server.c.
1018 * Cancel protocol timeouts always before calling the final
1019 callback, to assure that after final callback is called
1020 no other state will be called for the protocol anymore.
1021 Affected file silcd/protocol.c.
1023 * Print error log if incoming connection configuration could
1024 not be found. Affected file silcd/server.c.
1026 * Fixed JOIN command to correctly save the founder mode
1027 to the client on normal SILC server, when the channel
1028 was created by the router. Affected file silcd/command.c.
1030 * Fixed LIST command (hopefully) to send correct reply
1031 packets. Affected file silcd/command.c.
1033 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * The silc_packet_receive_process now returns FALSE if the
1036 read data was invalid packet, and TRUE if it was ok.
1038 The server now checks that if unauthenticated connection
1039 sends data and its processing fails the server will close
1040 the connection since it could be a malicious flooder.
1042 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1044 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1046 * Make sure the warning about error opening a log file is
1047 printed only once and not everytime it fails (produces
1048 too much useless log). Affected file lib/silcutil/silclog.c.
1050 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1052 * Made the silc_server_daemonise() function more readable.
1053 Affected file silcd/server.c.
1055 * Pid file is now optional, the user may comment it out from
1056 the config file. Removed define SILC_SERVER_PID_FILE, we
1057 don't need a default any longer. Affected file
1058 configure.in.pre, lib/Makefile.am.pre.
1060 * Make some use of the pid file. The server now dies at startup
1061 if it detects a valid pid file on his path. The server would
1062 die anyway in this circumstance, because of the bind() failure.
1063 Affected file silcd/silcd.c.
1065 * No longer compiling lib/dotconf.
1067 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Fixed JOIN command parsing not to crash. Affected file
1070 lib/silcclient/command.c.
1072 * Fied the NICK_CHANGE notify to add the new client entry
1073 even it is resolved. This removes an <[unknown]> nick
1074 thingy bug in the client. Affected file is
1075 lib/silcclient/client_notify.c.
1077 * Do not try to allocate 0 bytes (efence does not like it)
1078 in lib/silccore/silccomand.c when encoding payload.
1080 * Do not take IRCNICK as nickname in Irssi SILC client since
1081 it is not possible to set nickname before hand connecting
1082 the server (TODO has an entry about adding auto-nicking
1085 * Changed the silc_server_command_pending to check whether
1086 there already exists an pending entry with the specified
1087 command, command identifier and pending callback. This is
1088 to fix IDENTIFY and WHOIS related crashes that may register
1089 multiple pending commands with same identifier. Affected
1090 file silcd/command.c.
1092 * Fixed the server to reconnect to the router even if it
1093 was already reconnecting and EOF was received. This to
1094 fix a possibility that the server wouldn't ever try to
1095 auto-reconnect to the router. Affected file silcd/server.c.
1097 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1099 * Fixed the server's password authentication to use the
1100 length of the locally saved password, and not the one
1101 sent in the packet. Affected file silcd/protocol.c.
1103 * Fixed same password authentication problem in the
1104 Authentication Payload handling routines in
1105 lib/silccore/silcauth.c.
1107 * Yet another password authentication problem fixed with
1108 channel password handling in silcd/command.c.
1110 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * If first character of string in silc_parse_userfqdn is '@'
1113 then do not parse it. Affected file is
1114 lib/silcutil/silcutil.c.
1116 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1118 * Fixed minor bug in IDENTIFY command reply sending, which
1119 caused various weird problems during JOIN when it was
1120 resolving names for users. Affected file silcd/command.c.
1122 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1124 * Fixed the IDENTIFY command reply sending to chech better valid
1125 clients. It was possible to send incomplete list of replies.
1126 Affected file silcd/command.c.
1128 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1130 * Added silc_client_command[s]_[un]register functions now to
1131 dynamically register the commands in client library. Removed
1132 the static table of commands. This allows the client library
1133 to call commands without causing the application to know about
1134 what commands library has called.
1136 Removed the INFO command reply kludge to detect when the command
1137 was called by library. Now library use its own command reply
1138 function for INFO command.
1140 Added function silc_client_command_call to call a command.
1141 Application can use it to call command, not access the structure
1144 Now all commands that are sent by the client library (not
1145 explicitly sent by application) use own command reply functions.
1147 Affected files around lib/silcclient/ and in
1148 irssi/src/silc/core/.
1150 * Fixed the WHOIS command reply sending to chech better valid
1151 clients. It was possible to send incomplete list of replies.
1153 Fixed the WHOIS and IDENTIFY to send the request to router
1154 if normal server did not do it and did not find any results.
1156 Affected file silcd/command.c.
1158 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1160 * Moved the internal data from SilcClient context into its
1161 own file, not accesible to application. Affected files
1162 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1163 and other files in client library.
1165 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Added doc/examples installation target in Makefile.am.pre.
1170 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1173 commands the found client entry will be removed from the
1174 cache, after notifying application about the error. Affected
1175 file lib/silcclient/command_reply.c.
1177 * Changed the /MSG to check for exact nickname user gave, and
1178 not let `nick' match `nick@host' if it is only one found. Now,
1179 user must type the exact nickname (like nick@host2) even if
1180 there are no more than one same nicks found. This is to avoid
1181 a possibility of sending nickname to wrong nickname since
1182 `nick' could match `nick@host'. Affected file is
1183 irssi/src/core/silc-servers.c.
1185 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Do not print "you are now server operator" or similar when
1188 giving /away command. Affected files are
1189 irssi/src/silc/core/client_ops.c, silc-servers.h.
1191 * Made the silc_server_command_pending_error_check to send
1192 the same command reply payload it received back to the
1193 original sender of the command. This way all arguments
1194 that was received by the server will be received by the
1195 client too. Affected file silcd/command.c.
1197 * Added the silc_idcache_add to return the created cache entry
1198 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1200 * Add global clients to expire if they are not on any channel.
1201 This is because normal server will never know if they signoff
1202 if they are not on any channel. The cache expiry will take
1203 case of these entries. This is done by normal servers only.
1204 The affected files are silcd/command_reply.c,
1205 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1207 * If server receives invalid ID notification for WHOIS or
1208 IDENTIFY and the ID exists in the lists, it is removed.
1209 Affected file silcd/command_reply.c.
1211 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1212 in client then client entry that it matches is searched and
1213 the nickname is printed on the screen for user. Affected
1214 file irssi/src/silc/core/client_ops.c.
1216 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Use cache entry expire time in the LIST command reply to
1219 purge old entries from the cache after the LIST command
1220 reply has been received. This way we don't have non-existent
1221 entries in the cache for too long. Affected file is
1222 silcd/command_reply.c.
1224 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * If we are normal server, and we've not resolved client info
1227 in WHOIS or IDENTIFY from router, and it is global client,
1228 we'll check whether it is on some channel. If it is not
1229 then we cannot be sure about its validity and will resolve it
1230 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1231 file silcd/command.c.
1233 * Search channel by name (if possible) rather than by ID
1234 in IDENTIFY command's command reply. Affected file is
1235 silcd/command_reply.c.
1237 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1240 Updated specs and implemented it. Affected file silcd/command.c,
1241 silcd/packet_send.c and silcd/packet_receive.c.
1243 * Implemented the <founder auth> payload handling in the JOIN
1244 command. If provided all conditions for channel joining
1245 except requirement to provide correct passphrase can be
1246 overrided by the channel founder. Updated the protocol specs.
1247 Affected file silcd/command.c.
1249 Added support for founder auth in JOIN command in client
1250 library. Fixed the parsing of the JOIN command now to support
1251 all options as they should be. The affected file is
1252 lib/silcclient/command.c.
1254 * Optimized the WHOIS and IDENTIFY commands to send the request
1255 to router only if it includes nicknames or other names. If
1256 they include only IDs then check the local cache first before
1257 routing. Affected file is silcd/command.c.
1259 * Added channels topic announcements. Affected file is
1260 silcd/packet_receive.c and silcd/server.c.
1262 * Fixed the silc_server_send_notify_topic_set to really destine
1263 the packet to channel. Affected file silcd/packet_send.c.
1265 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1266 library. Affected file lib/silcclient/client_notify.c.
1268 * Added UMODE announcements. Affected file silcd/server.c.
1270 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1272 * Memory leak fixes in:
1274 lib/silcutil/silcsockconn.c
1275 lib/silcske/silcske.c
1276 lib/silcske/groups.c
1278 lib/silccrypt/silcpkcs.c
1279 lib/silccore/silccommand.c
1280 lib/silccore/silcidcache.c
1285 * ROBOdoc documented the lib/silcske/groups.h file and a
1286 bit changed the interface for better.
1288 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1290 * Update the client entry context in the ID cache after
1291 nick change. Affected file lib/silcclient/command.c.
1292 Fixes the CUMODE command when regaining founder privileges,
1293 and a little WHOIS problem.
1295 * Fixed silc_net_gethostbyname to correctly call the
1296 inet_ntop. Affected file lib/silcutil/silcnet.c.
1298 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1300 * Added IPv6 support checking to the configure.in.pre, added
1301 also --enable-ipv6 option to override the check. Affected
1302 file configure.in.pre.
1304 * The silc_thread_create now calls the start function
1305 directly if threads support is not compiled in. Removes
1306 ugly #ifdef's from generic code. Affected files are
1307 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1309 * Added silc_net_gethostby[name/addr]_async to asynchronously
1310 resolve. Affected files are lib/silcutil/silcnet.[ch].
1312 * Added support for rendering IPv6 based server, client and
1313 channel IDs. Affected file lib/silcutil/silcutil.c.
1315 * Added support for creating IPv6 based server IDs. Affected
1316 file is silcd/serverid.c.
1318 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1320 * Added silc_net_gethostby[addr/name] into the
1321 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1322 routines. Added silc_net_is_ip[4/6]. Affected file is
1323 lib/silcutil/unix/silcunixnet.c. All routines that take
1324 address as argument now supports both IPv4 and IPv6 addresses.
1326 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1328 * Fixed LIST command reply sending in server. Affected file
1331 * Server now sends the kicker's client ID in the KICK notify
1332 to the kicked client. Affected file silcd/command.c.
1334 * The client library now parses the kickers client ID and
1335 UI displays it. Affected files lib/silcclient/client_notify.c
1336 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1338 * Made all payload parsing function prototypes consistent.
1339 They all take now const unsigned char * and uint32 pair as
1340 the payload data instead of SilcBuffer. Changes all around
1341 the source tree. Other unsigned char* -> const unsigned char*
1342 changes around the tree as well.
1344 * Optimized SFTP client and server packet sending not to
1345 allocate new buffer for each packet but to recycle the
1346 first allocated buffer. Affected files are
1347 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1349 * Optimized the SFTP client to use SilcList instead of
1350 SilcDList for requests, because it is faster. Affected file
1351 is lib/silcsftp/sftp_client.c.
1353 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1354 into lib/silccore/silcid.[ch].
1356 Renamed silcpayload.[ch] into silcargument.[ch].
1358 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1360 * If client entry is deleted with active key agreement
1361 session, abort the session.
1363 The silc_client_abort_key_agreement now calls the completion
1364 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1366 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1369 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Don't use __restrict in older GCC's. Affected file is
1372 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1374 * silc_net_localhost now attempts to reverse lookup the
1375 IP/hostname. Affected file lib/silcutil/silcnet.c.
1377 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1378 command. It can be used to gain founder privileges at
1379 the same time when joining the channel.
1381 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1382 kicker's client ID as well. Updated protocol specs.
1384 Defined that the server must send SILC_COMMAND_IDENTIFY
1385 command reply with error status to client who sent
1386 private message with invalid client ID.
1388 Updated the protocol specification.
1390 * Added silc_server_send_command_reply to send any
1391 command reply. Affected file silcd/packet_send.[ch].
1393 * Added silc_id_payload_encode_data to encode ID payload
1394 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1396 * The server now send IDENTIFY command reply with error
1397 status if client ID in private message is invalid. Affected
1398 file silcd/packet_receive.c.
1400 * Save the server key file with server's IP address in
1401 the filename instead of hostname. The affected file is
1402 irssi/src/silc/core/client_ops.c.
1404 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1409 * Added libtool support for compiling shared objects in
1410 lib/silcsim. Affected file configure.in.pre and
1411 lib/silcsim/Makefile.am. Original patch by cras.
1413 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Pid file configuration, and server's config file fixes
1416 patch by toma. Updated CREDITS file.
1418 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Fixed silc_client_channel_message to not try to decrypt
1421 the message twice if it resolved the destination client
1422 information. This could cause of dropping one channel
1423 message. Affected file lib/silcclient/client_channel.c.
1425 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1428 lib/silcclient/client.c. This function is used when the SILC
1429 Client is run under some other scheduler, or event loop or
1430 main loop. On GUI applications, for example this may be
1431 desired to used to run the client under the GUI application's
1432 main loop. Typically the GUI application would register an
1433 idle task that calls this function multiple times in a second
1434 to quickly process the SILC specific data.
1436 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1438 * Fixed silc_server_drop() for dropping the supplementary
1439 groups as well, this could cause a security hole on some
1442 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1447 * Write PID file after dropping privileges. Added -F option
1448 to run server on foreground. A patch by debolaz.
1449 Affected files silcd/server.c, silcd/silcd.c.
1451 * Fixed MOTD to return the MOTD file server name. Affected
1452 file silcd/command.c.
1454 * Added INFO command reply handling to the Irssi SILC Client.
1455 Affected file irssi/src/silc/core/client_ops.c.
1457 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed the silc_idcache_list_* routines to really support
1460 the dynamic list. Fixes a crash. Affected file is
1461 lib/silccore/silcidcache.c.
1463 * Fixed the LIST command reply to really call LIST command's
1464 pending callbacks. Affected file silcd/command_reply.c.
1466 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Update conn->local_entry->nickname after giving NICK
1469 command. Affected file lib/silcclient/command.c.
1471 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1473 * Added the [pid] option to the silcd configuration file
1475 Affected files: serverconfig.[ch] and silcd.c
1477 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Save fingerprint in WHOIS command reply in server.
1480 Affected file silcd/command_reply.c.
1482 * Fixed NICK commands pending callback registration.
1483 Affected file lib/silcclient/command.c.
1485 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Use ++server->cmd_ident when sending commands in server,
1488 instead of random number. Affected file silcd/command.c.
1490 * Fixed GETKEY command reply to call actually GETKEY pending
1491 command callbacks. Affected file silcd/command_reply.c.
1493 * A bit stricter check for nicknames. Check for same nickname
1494 in NICK command also. Affected file silcd/command.c.
1496 * Do not call INFO command everytime client ID changes, only
1497 during first connecting. Affected file lib/silcclient/client.c.
1499 * Set the new nickname only after successful command reply for
1500 NICK command is returned by server. Affected file
1501 lib/silcclient/command.c.
1503 * Remove nicknames from nicklist during server_signoff notify.
1504 Should fix /NAMES bit more. The affected file is
1505 irssi/src/silc/core/silc-channels.c.
1507 * Added `fingerprint' field to the SilcIDListData in the
1508 silcd/idlist.h to hold the fingerprint of the client's
1511 Send the fingerprint of the client's public key in WHOIS
1514 Affected files silcd/command.c, and silcd/idlist.[ch].
1516 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1517 create fingerprint from given data.
1519 * Show the fingerprint of the client's public key in WHOIS.
1520 Affected files irssi/src/module-formats.[ch] and
1521 irssi/src/silc/core/client_ops.c.
1523 * Format the multiple same nicknames also during JOIN and
1524 NICK_CHANGE notifys. Affected file is
1525 lib/silcclient/client_notify.c.
1527 * Do not print error on screen for invalid private message
1528 payload since it can come if someone is sending private
1529 messages with wrong key. Affected file
1530 lib/silccore/silcprivate.c.
1532 * Fixed multiple concurrent /PING crash. Affected file
1533 lib/silcclient/command.c.
1535 * Changed the wrong ID encoding. All IP addresses must be
1536 in MSB first order in encoded format. They were encoded
1537 wrong and was in LSB format. Affected files are
1538 silcd/serverid.c, lib/silcutil/silcutil.c.
1540 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1542 * Call the `connect' client operation through the scheduler
1543 in case of error. Affected file lib/silcclient/client.c.
1545 * Call the `failure' client operation even if the error
1546 occurred locally during a protocol. Affected file is
1547 lib/silcclient/protocol.c.
1549 * Added support of sending LIST command to router from normal
1550 server. This way normal server can get list of all channels
1551 in the network too. Fixed the channel list sending in the
1552 server too. Affected files are silcd/command.c, and
1553 silcd/command_reply.[ch].
1555 * Added silc_server_update_channels_by_server and
1556 silc_server_remove_channels_by_server. They are used during
1557 disconnection of primary router and in backup router protocol.
1558 Affected file silcd/server_util.[ch], silcd/server.c and
1559 silcd/server_backup.c.
1561 * Fixed channel adding to global list in IDENTIFY command
1562 reply in server. Affected file silcd/command_reply.c.
1564 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * If the incoming packet type is REKEY or REKEY_DONE process
1567 that packet always synchronously. Fixes yet another MAC
1568 failed error on slow (dialup) connections. Affected file
1569 lib/silcclient/client.c and silcd/server.c.
1571 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Call check_version SKE callback for initiator too. Affected
1574 file lib/silcske/silcske.c.
1576 * Implemented fix for security hole found in the SKE that was
1577 fixed in the specification few days back; the initiator's
1578 public key is now added to the HASH value computation.
1579 Added backwards support for the old way of doing it too, for
1580 old clients and old servers. Affected file is
1581 lib/silcske/silcske.c.
1583 * Enabled mutual authentication by default in SKE. If initiator
1584 is not providing mutual authentication the responder will
1585 force it. This will provide the proof of posession of the
1586 private key for responder. The affected files are
1587 lib/silcclient/protocol.c and silcd/protocol.c.
1589 * Do not cache anymore the server's public key during SKE.
1590 We do mutual authentication so the proof of posession of
1591 private key is done, and if the server is authenticated in
1592 conn auth protocol with public key we must have the public
1593 key already. Affected file silcd/protocol.c.
1595 * Added new global debug variable: silc_debug_hexdump. If
1596 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1597 file lib/silcutil/silclog.[ch].
1599 * Fixed compilation warning due to char * -> const char *.
1600 Affected files lib/silcutil/silcnet.h, and
1601 lib/silccore/silcauth.[ch].
1603 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1605 * Fixed CMODE command when new channel key was created. If
1606 the creation failed the old key was removed. Next time giving
1607 same command would crash the server since the old key was
1608 freed already. Affected file silcd/command.c.
1610 * Fixed the silc_server_announce_get_channels to not crash
1611 on reconnect. Affected file silcd/server.c.
1613 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Added silc_log_set_debug_string function to set a regex
1616 string to match for debug output. Only the function names,
1617 or filenames matching the given debug string is actually
1618 printed. This way it is possible to filter out those debug
1619 strings that user is not interested in.
1621 Fixed a bug in silc_string_regexify.
1623 Affected files lib/silcutil/silclog.[ch], and
1624 lib/silcutil/unix/silcunixutil.c.

1627 to take the debug string as argument. Affected files
1628 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1630 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Added silc_hash_babbleprint to create a Bubble Babble
1633 Encoded fingerprint. The encoding is developed by Antti
1634 Huima (draft-huima-babble-01.txt), and it creates human
1635 readable strings out of binary data. Affected file
1636 lib/silccrypt/silchash.[ch].
1638 * Print the babble print now in addition of fingerprint as well
1639 in Irssi SILC client. Affected files are
1640 irssi/src/fe-common/silc/module-formats.[ch],
1641 irssi/src/fe-common/silc/core/client_ops.c.
1643 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1645 * Fixed a security problem found in SKE. The initiator's
1646 public key too is now added to the HASH hash value creation
1647 which is signed by the responder to create the SIGN value.
1648 This will prevent anyone in the middle to lie to the responder
1649 about the initiator's public key. If this is done now, the
1650 man in the middle will get caught. Updated the protocol
1653 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Better installation directory handling. Configure module
1656 paths and other paths automatically to example_silc* files
1657 in doc/. A patch by toma.
1659 * Fixed compiler warning from MPI library, and from SILC RNG.
1662 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1663 It can be configured with ./configure. A patch by toma.
1665 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Find correct make to use in prepare-clean. A patch by
1668 toma. Affected file prepare-clean.

1689 * Added silc_pkcs_public_key_compare to compare two
1690 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1692 * Check that the client who set the founder mode on the
1693 channel is the same client that is giving the founder
1694 mode to itself. It is done by comparing the saved public
1695 key (it is saved even in the authentication is passphrase).
1696 Affected file silcd/command.c.

1703 * Process the DISCONNECT packet through scheduler in the
1704 client library. Affected file lib/silcclient/client.c.
1706 * Fixed the silc_client_packet_parse to not to increase
1707 the packet sequence number if the conn->sock and the
1708 current socket connection is not same. This can happen
1709 for example during key agreement when the conn includes
1710 multiple socket connections (listeners). Affected file
1711 lib/silcclient/client.c.
1713 * The sender of the file transfer request now provides also
1714 the pointer (listener) for the key exchange protocol. If
1715 the listener cannot be created then it sends empty key
1716 agreement and lets the receiver provide the listener.
1718 Added `local_ip' and `local_port' arguments to the
1719 silc_client_file_send. If they are provided they are used,
1720 if not then it will attempt to find local IP address, if
1721 not found or bind fails then the remote client will provide
1724 Affected files are lib/silcclient/client_ftp.c and
1725 lib/silcclient/silcapi.h.
1727 * Extended the FILE SEND command to support defining the
1728 local IP and port for key exchange listener. They are
1729 optional. Affected file irssi/src/silc/core/silc-servers.c.

1733 * Defined to WHOIS command reply the sending of fingerprint
1734 of the client's public key (if the proof of posession of the
1735 corresponding private key is verified by the server).
1736 Updated to the protocol specification.
1738 * Added support of receiving the client's public key's
1739 fingerprint in command reply in client library. Affected
1740 file is lib/silcclient/command_reply.c, and
1741 lib/silcclient/idlist.[ch].
1743 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1796 client library. Affected file lib/silcclient/client_prvmsg.c.
1798 * Do not actually remove the client directly from ID cache
1799 during SERVER_SIGNOFF, but invalidate it. This way we
1800 preserve the WHOWAS info for the client. Affected file
1801 silcd/server_util.c.
1803 * Fixed SERVER_SIGNOFF notify handling in the server. The
1804 server is now able to process incoming SERVER_SIGNOFF notify
1805 for a server that it doesn't even know about. It will remove
1806 the clients provided in the notify. Affected file
1807 silcd/packet_receive.c.
1809 * Check for partial packet in data queue after every packet that
1810 was found from the queue. Return and wait for more data if
1811 there is partial data in queue. Affected file is
1812 lib/silccore/silcpacket.c.
1814 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1829 irssi/src/fe-common/silc/module-formats.[ch].
1831 * Wrote a help file for FILE command.
1833 * Added silc_rng_global_get_byte_fast to get not-so-secure
1834 random data as fast as possible. Random data is read from
1835 /dev/urandom if available and from the SILC RNG if not
1836 available. It is used in padding generation. Affected file
1837 lib/silccrypt/silcrng.[ch].
1839 * All packets in client library are now processed synchronously.
1840 Optimized packet processing a lot. Affected file
1841 lib/silcclient/client.c.
1843 * All server connection packets are processing synchronously
1844 now in server, to optimize packet processing. Affected file
1847 * Include files are installed now only in Toolkit distribution
1848 if make install is given. Affected files: all Makefile.am's.
1850 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Assure that silc_client_notify_by_server_resolve does not
1853 resolve the client information multiple times. If it cannot
1854 be found by the first it cannot be found at all. Affected
1855 file lib/silcclient/client_notify.c.
1857 * Fixed WHOWAS command reply calling. Affected file
1858 lib/silcclient/command_reply.c.
1860 * Removed all references to silc_idlist_get_client from the
1861 Irssi SILC client since that call is internal call used by
1862 the library. The Irssi SILC client will use now client
1863 retrieval functions found in silcapi.h.
1865 * Fixed a bug in resolving nickname info before sending
1866 private message. It used freed memory. Affected file
1867 irssi/src/silc/core/silc-servers.c.

1888 * Added silc_net_localip to return local host's IP address.
1889 Affected file lib/silcutil/silcnet.[ch].
1891 * If key exchange or rekey protocol is active for a connection
1892 parse all packets syncronously since there might be packets
1893 in packet queue that we are not able to process without first
1894 processing packets before them. Affected file silcd/server,
1895 lib/silcclient/client.c.
1897 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1898 whether library should continue processing the packet.
1899 Affected file lib/silccore/silcpacket.h.
1901 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1945 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1946 is incomplete and is being resolved, it won't be resolved
1949 Make sure also that USERS command reply does not resolve
1950 twice information. Affected file is
1951 lib/silcclient/command_reply.c.
1953 Make sure that silc_client_get_clients_by_list does not
1954 resolve twice same information.
1956 * Check for valid client->id in the silc_server_free_client_data.
1957 Affected file silcd/server.c.
1959 * Fixed /GETKEY nick@server not to crash if the server entry
1960 is not found. Affected file lib/silcclient/command.c.

1972 * Call the silc_server_udpate_servers_by_server in the
1973 primary router that comes back online in the backup resuming
1974 protocol. Otherwise it routes packets wrong. Affected file
1975 silcd/server_util.[ch], silcd/server_backup.c.
1977 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1980 lib/silcutil/silcbuffmt.[ch].
1982 * Redefined the SILC packet header to include the padding
1983 length. Affected file lib/silccore/silcpacket.[ch].
1985 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1986 length for maximum padding up to 128 bytes). Affected
1987 file lib/silccore/silcpacket.h.
1989 * Removed all backwards support for old 0.5.x MAC thingies.
1990 The SILC packet header change makes it impossible to be
1991 backwards compatible.
1993 * Send the ENDING packet with timeout in the backup resuming
1994 protocol. This is to assure that all routers has connected
1995 to the primary router. Affected file silcd/server_backup.c.
1997 * Changed the RNG to take the first IV from random data. It
1998 used to take it from zero actually. Changed the RNG also
1999 to use /dev/urandom during session. /dev/random is used
2000 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2002 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2005 (the packet length) encrypted. Affected files aroung the
2006 code tree, lib/silccore/silcpacket.[ch]. Removed the
2007 SilcPacketCheckDecrypt callback. It is not needed anymore
2008 since the silc_packet_receive_process will determine now
2009 whether the packet is normal or special.
2011 * Implemented the unidirectional MAC keys. Affected files
2012 lib/silcske/silcske.c, silcd/protocol.c and

2022 * Allow backup router to announce servers. All servers
2023 announced by backup router are added to the global list
2024 automatically. Update hte server's socket to our primary
2025 router also when backup router announces a server.
2026 Affected file silcd/packet_receive.c.
2028 * Do not update the client->router in the function
2029 silc_server_udpate_clients_by_server if the client is on
2030 global list. We might fail to find any specific server
2031 for locally connected clients and local cell clients. They
2032 should still use the `from' and not `to' as client->router.
2033 This fixes backup router resuming protocol. Affected file
2034 silcd/server_util.c.
2036 * Decrease channel statistics count only if the channel
2037 deletion worked. Affected files are silcd/server.c and
2038 silcd/server_util.c.
2040 * Added silc_server_update_servers_by_server to update origin
2041 of all server entries. Used during backup router protocol.

2050 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Assure that router cannot reroute the same channel message
2053 to the sender. Affected file silcd/packet_receive.c.
2055 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Made better checks that the channel message is not sent
2058 to the router it came from. Affected file is
2059 silcd/packet_send.c. Fixed memory leak too.
2061 * Announce informations for incoming router connection, but
2062 only after checking if it is replaced by backup router.
2063 Affected file silcd/packet_receive.c.
2065 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2068 router environment. Affected file silcd/server_backup.c.
2070 * Route packet only to one router in the function
2071 silc_server_packet_send_to_channel. Affected file is
2072 silcd/packet_send.c.
2074 * Fixed silc_server_send_notify_dest to set the broadcast
2075 flag. Fixed the silc_server_send_notify_topic to actually
2076 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2077 Affected file silcd/packet_send.c.
2079 * Changed the SFTP Filesystem interface. Changed the
2080 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2081 the filesystem operation function. The SilcSFTPFilesystem
2082 is now a context that is allocated by all filesystem allocation
2083 functions and it already includes the operations structure
2084 and filesystem specific context. It is given as argument
2085 now to the silc_sftp_server_start. This made the interface
2086 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2087 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2089 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Changed the backup router adding and getting interfaces
2092 in the server. The router that will be replaced by the
2093 specified backup router is now sent as argument. Affected
2094 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2097 * Added silc_net_addr2bin_ne to return the binary form of
2098 the IP address in network byte order. Affected files

2114 * Wrote the definition of the backup resuming protocol to the
2115 protocol specification.
2117 * Removed one redundant channel key generation from normal
2118 server during joining procedure. Removed one redundant
2119 channel key sending from server to router during joining
2120 procedure. Affected file silcd/command.c.
2122 * Made minor bugfixes to the backup router resuming protocol.
2123 Affected file silcd/server_backup.c, server.c.

2132 resume the primary router position in the cell after the
2133 primary router comes back online. Affected files
2134 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2135 and silcd/server_util.[ch].
2137 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2139 * Sleep two (2) seconds after sending QUIT command to server.
2140 Affected file lib/silcclient/command.c.
2142 * Assure that if outgoing data buffer is pending do not force
2143 send any data. Affected file silcd/packet_send.c.
2145 * Assure that if outgoing data buffer is pending do not force
2146 send any data. Affected file lib/silcclient/client.c.
2148 * Implemented the backup router support when the primary router
2149 goes down. The servers and routers can now use the backup
2150 router as new primary router without loosing connectivity.
2152 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2155 in the server to indicate disabled entry. All data read
2156 from the connection will be ignored and no data is sent
2157 for entry that is disabled. Affected files are
2158 silcd/idlist.h, silcd/server.c.
2160 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Created SFTP client and server test programs in the
2163 lib/silcsftp/tests directory.
2165 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Implemented memory filesystem (virtual filesystem) for
2168 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2171 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2173 * Implemented the SFTP (SSH File Transfer Protocol) to the
2174 lib/silcsftp. It includes SFTP client and SFTP server
2177 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Moved lib/silccore/silcprotocol.[ch] to the
2180 lib/silcutil library.
2182 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2183 take variable argument list pointer as argument. Affected
2184 file lib/silcutil/silcbuffmt.[ch].
2186 * Added silc_buffer_set function that is used to set data
2187 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2188 Affected file lib/silcutil/silcbuffer.h.
2190 * Changed various routines in the core library to use the new
2191 silc_buffer_set instead of allocating new buffer only for
2194 * Added 64-bit value formatting and unformatting support to the
2195 silc_buffer_[un]format routines. Affected file is
2196 lib/silcutil/silcbuffmt.[ch].
2198 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2199 to includes/bitmove.h.
2201 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2203 * Fixed channel user mode saving in client library. Affected
2204 file lib/silcclient/command[_reply].c.
2206 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Defined the file transfer to the SILC Protocol. Added
2209 new packet type SILC_PACKET_FTP and defined File Transfer
2210 Payload. The mandatory file transfer protocol is SFTP
2211 (SSH File Transfer Protocol). Affected file in addition
2212 of the internet draft is lib/silccore/silcpacket.h.
2214 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2215 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2216 is used as part of backup router protocol when the primary
2217 router of the cell is back online and wishes to resume
2218 the position as primary router.
2220 * Redefined the MAC generation keys in the protocol. The
2221 same key is not used anymore in both direction. Both
2222 direction will now use different keys for sending and
2223 receiving. This fixes a potential security flaw. This
2224 change causes incompatibilities in the protocol.
2226 * Redefined also the MAC computation from the packet.
2227 An packet sequence number is now added to the MAC
2228 computation. This prevents possible replay attacks against
2229 the protocol. This change too causes incompatibilities
2232 Added `sequence' field to the SilcPacketContext to hold
2233 the current sequence number for the packet.
2235 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Added `created' field to the SilcIDListData in the file
2238 silcd/idlist.h to indicate the time when the entry was
2241 * Added `created' field to the SilcChannelEntry too. Affected
2242 file silcd/idlist.h.
2244 * Added `creation_time' aguments to all the announcement functions
2245 in the server. If it is provided then only the entries that
2246 was created after the provided time frame are actually
2247 announced. Affected file silcd/server.[ch].
2249 * The protocol says that the Channel ID's IP address must be
2250 based on the router's IP address. Added check for this in
2251 the silc_server_new_channel when processing incoming New Channel
2252 Payload. Affected file silcd/packet_receive.c.
2254 * Print out the correct version with --version in SILC client.
2255 Affected file irssi/src/silc/core/silc-core.c.
2257 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Fixed WHOWAS command to check for completnes of the client
2260 entry always, not just when the command is coming from client.
2261 Affected file silcd/command.c.
2263 * Added new function silc_server_packet_queue_purge to purge the
2264 outgoing data queue to the network. After the function returns
2265 it is guaranteed that the outgoing packet queue is empty.
2266 Affected file silcd/packet_send.[ch].
2268 * Purge the outgoing packet queue in the rekey protocol's final
2269 callback to assure that all rekey packets go to the network
2270 before quitting the protocol. Affected file silcd/server.c.
2272 * Added silc_client_packet_queue_parse as similar function as
2273 in server to the client library. The affected file is
2274 lib/silcclient/client.c.
2276 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Splitted silcd/server.c and created silcd/server_util.[ch]
2279 for utility functions.
2281 * Added new socket flag SILC_SF_DISABLED to indicate that the
2282 connection is open but nothing can be sent to or received from
2283 the connection. Affected file lib/silcutil/silsockconn.[ch].
2284 The checking for disabled socket is checked in the low level
2285 silc_socket_write and silc_socket_read functions.
2287 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Allow only nicknames and channel names that fits into the
2290 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2292 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * When processing JOIN command reply in server check that if
2295 the channel exists in our global list we'll move it the local
2296 list. Affected file silcd/command_reply.c.
2298 * Fixed the check whether client is joined on the channel already
2299 in JOIN command. Affected file lib/silcclient/command.c.
2301 * Fixed the JOIN command reply to check whether the channel
2302 already exists. Affected file lib/silcclient/command_reply.c.
2304 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Added silc_ske_status_string to map the SKE error numbers
2307 to readable strings. The affected files are
2308 lib/silcske/silcske[_status].[ch].
2310 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Do not show the private channels on the WHOIS channel list
2313 as it is not allowed by the protocol. The affected file is
2316 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Assure that the packet length digged from the actual packet
2319 is something sensible in the silc_packet_decrypt_rest_special
2320 in lib/silccrypt/silcpacket.c.
2322 * Free and NULL the allocated pointer in silc_hmac_alloc if
2323 the HMAC allocation fails. The affected file is
2324 lib/silccrypt/silchmac.c.
2326 * Print the selected security properties to the log files in
2327 the server. Affected file silcd/protocol.c.
2329 * Add SKE's reference counter even if calling the completion
2330 callback manually. Otherwise it goes negative, although it
2331 does not cause any problems. The affected file is
2332 lib/silcske/silcske.c.
2334 * Remove the client entry with short timeout after giving the
2335 KILL command. Affected file lib/silcclient/command.c.
2337 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2338 case all found clients are already disconnected (WHOWAS would
2339 found them) in the server. Affected file silcd/command.c.
2341 * Update the last_receive (time of last data received) to be
2342 updated only when received private or channel message so that
2343 the idle time showed in WHOIS makes more sense.
2345 * Added boolean field `valid' in to the SilcClientEntry in the
2346 client library to indicate whether the entry is valid or not.
2347 This fixes the nickname change bug on channel when changing
2348 the nickname to be same than the old (like nick to Nick) the
2349 nickname formatter doesn't set the new nick anymore to Nick@host.
2350 Affected file lib/silcclient/idlist.[ch].
2352 * Now actually fixed the nickname changing on disconnection.
2353 Added new function silc_change_nick to the Irssi SILC Client.
2354 Affected file irssi/src/silc/core/client_ops.c,
2355 irssi/src/silc/core/silc-nicklist.[ch].
2357 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Check that the public key exists in the GETKEY command before
2360 trying to encode it. Affected file silcd/command.c.
2362 * Print some notifications on received public keys with GETKEY
2363 command in the Irssi SILC Client. Affected files are
2364 irssi/src/fe-common/silc/module-formats.[ch],
2365 irssi/src/silc/core/client_ops.c.
2367 * Use IDENTIFY command to resolve the server information in the
2368 GETKEY command instead of INFO command. Affected file
2369 lib/silcclient/command.c.
2371 * All command reply functions in the client library now calls
2372 the pending command reply callbacks even if an error has
2373 occurred. The server has done this a long time and now it was
2374 time to move the client library to this as well. Now all
2375 errors can be delivered back to the pending command reply
2376 callbacks if necessary. Affected files are
2377 lib/silcclient/command[_reply].[ch].
2379 * Change the nickname on disconnection back to the username
2380 because in reconnect the server will enforce it to it anyway.
2381 Affected file irssi/src/silc/core/silc-servers.c.
2383 * Fixed a config file parsing bug in the Irssi SILC client.
2384 Affected file irssi/src/silc/core/clientconfig.c.
2386 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * When printing the channel mode on JOIN, verify that the
2389 channel key and channel's HMAC are valid. Affected file
2390 irssi/src/silc/core/client_ops.c.
2392 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2395 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2396 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2398 * Removed channel key rekey task deleting from the function
2399 silc_server_save_channel_key. Affected file silcd/server.c.
2400 Added explicit timeout task context instead that is used to
2401 delete the task if we are registering a new task before the
2402 new task has elapsed.
2404 * When channel key rekey occurs the client library now saves
2405 the old channel key for a short period of time (10 seconds) and
2406 is able to use it in case some is still sending channel
2407 messages encrypted with the old key after the rekey. Affected
2408 file lib/silcclient/[idlist.h|client_channel.c].
2410 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Added check to the silc_server_new_id_real to not accept
2413 new ID if it is the sender's own ID. Affected file is
2414 silcd/packet_receive.c.
2416 * Assure that we do not announce ourself or the one we've
2417 sending our announcements when we're router and are announcing
2418 servers to our primary router. Affected file silcd/server.c.
2420 * Fixed silc_server_command_identify_check_client to assemble
2421 correct WHOIS packet. It send corrupted WHOIS packet and
2422 caused problem with router to router connections. Affected
2423 file silcd/command.c.
2425 Fixed also silc_server_command_whois_check the same way
2426 as for the IDENTIFY command.
2428 * Added new SilcIDListStatus to the server in the SilcIDListData
2429 structure. The status now includes the current status of
2430 the entry (like registered, resolved etc.). Affected file
2431 silcd/idlist.[ch]. Defined a bunch of different status types
2432 as well. This replaced the old boolean registered field as well.
2434 Added resolve_cmd_ident field to the SilcClientEntry structure
2435 too so that if the entry is for example being resolved so
2436 another command may attach to the same pending command reply
2437 without requiring to resolve the same entry again. This concept
2438 should optimize the WHOIS and the IDENTIFY resolving under
2439 heavy load by taking away unnecessary resolving for entries
2440 that are being resolved already.
2442 Added support for adding multiple pending commands for one
2443 command idenfier. Affected file silcd/command[_reply].[ch].
2445 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2446 before deleting the data. Otherwise the hash table will have
2447 freed data in comparison functions. Affected file is
2448 silcd/command_reply.c.
2450 * Fixed silc_idlist_replace_client_id to add the new entry to
2451 the cache with NULL nickname. Otherwise there will be invalid
2452 memory as the nickname after the nickname is freed. Affected
2453 file silcd/packet_receive.c.
2455 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2456 saved into wrong slots because the previous number of entries
2457 was not taken into account. Affected file silcd/idlist.c.
2458 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2460 * If we are router and we receive JOIN notify to a channel that
2461 does not have any users then notified client is marked as the
2462 channel founder, as it is it. The affected file is
2463 silcd/packet_receive.c
2465 * Added to the extended hash table API's table_del_*ext functions
2466 the destructor as argument too, so that the caller can decide
2467 which destructor to use or whether to use destructor at all.
2468 Affected file lib/silcutil/silchashtable.[ch].
2470 * Fixed ID Cache purging. It actually deleted the entries from
2471 the hash table after the data was freed. The hash table ended
2472 up comparing freed memory. The affected file is
2473 lib/silccore/silcidcache.c.
2475 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Fixed Irssi SILC client's KILL command's HELP syntax.
2479 * The USERS command now resolves the detailed user information
2480 if the userinfo field is missing. Affected file is
2481 lib/silcclient/command_reply.c.
2483 * Do not print error in silc_file_read if the read file does
2484 not exist. Just silently return NULL. Affected file is
2485 lib/silcutil/silcutil.c.
2487 * Fixed the silc_log_output to not wine about NULL filename
2488 and to not create some bogus " " filename. Affected file is
2489 lib/silcutil/silclog.c.
2491 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Fixed various printing bugs on the user interface in the
2494 Irssi SILC Client. Minor changes that were forgotten from
2497 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Fixed the configure.in.pre and the compilation and distribution
2500 environment to support the new autoconf 2.52. That version is
2501 now required to compile the CVS trunk.
2503 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2506 to generally parse user@fqdn format strings. Affected file
2507 lib/silcutil/silcutil.c.
2509 * Added nickname_format and nickname_force_format fields to the
2510 SilcClientParams structure. The first one defines the format
2511 for the nicknames that the library will enforce if the receives
2512 multiple same nicknames. The second one is boolean value and
2513 can be used to force the library to always enforce the format
2514 to the nicknames regardles whether there are multiple nicknames
2515 or not. This configurable formatting was employed to flexibly
2516 support accessing multiple nicknames from the user interface.
2517 The userinterface can now set the nicknames to what ever format
2518 they prefer. Affected file lib/silcclient/silcapi.h.
2520 Added function silc_client_nickname_format to the file
2521 lib/silcclient/idlist.c. It performs the nickname formatting.
2523 Added new field `hostname´ to the SilcClientEntry context.
2524 It holds the hostname of the client. Affected file is
2525 lib/silcclient/idlist.h.
2527 * Irssi SILC Client sets the nicknames in nick@hostn format.
2528 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2529 irssi/src/silc/core/silc-core.c.
2531 The WHOIS printing now also shows both the real nickname and
2532 the formatted nickname so that user knows how to access the
2533 user if there are multiple same nicknames cached. Affected
2534 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2535 printing formatting too to take the hostname now as a separate
2536 argument. The Affected file is
2537 irssi/src/fe-common/silc/modules-formats.[ch].
2539 * Changed the silc_client_get_clients_local to accept the formatted
2540 nickname as argument. It accepts the real nickname too but the
2541 formatted nickname can be used to find the true entry from
2542 multiple entries. Affected file lib/silcclient/silcapi.h and
2543 lib/silcclient/idlist.c.
2545 * Added nickname_format_parse field to the SilcClientParams.
2546 It is a callback function provided by the application to parse
2547 the nickname out of the formatted nickname string. The library
2548 calls it to get the nickname from the formatted string. Since
2549 the application generally knows better the format of the nickname
2550 string it parses it instead of the library, even though library
2551 encodes the formatted string. If the callback function is not
2552 provided then the library will use the string as is. The
2553 affected file is lib/silcclient/silcapi.h.
2555 * All the nickname strings passed to the client library in
2556 commands are now expected to be formatted nickname strings.
2557 If the command does not support the formatted nickname string
2558 it will assume that the sent string is the actual nickname.
2559 Affected file lib/silcclient/command.c.
2561 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2563 * Added public key authentication support to OPER and SILCOPER
2564 commands in the client library. Affected file is
2565 lib/silcclient/command.c.
2567 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Changed the get_auth_methdod client operation to be asynchronous.
2570 It can be async if the application resolves the authentication
2571 method from the server during the negotiation. Added new
2572 SilcGetAuthMeth completion callback that the application will
2573 call after resolving the authentication method.
2575 Added function silc_client_request_authentication_method that
2576 the application can use to resolve the authentication method
2577 from the server. Added also SilcConnectionAuthRequest callback
2578 that the library will call after the server has replied. The
2579 application can call this function if it does not know the
2580 current authentication method.
2582 Affected files are lib/silcclient/client.c and
2583 lib/silcclient/silcapi.h.
2585 * The Irssi SILC client now automatically resolves the authentication
2586 method incase any configuration information is not present (and
2587 currently there never is). The affected file is
2588 irssi/src/silc/core/client_ops.c.
2590 * Fixed public key authentication from the client library.
2591 Affected file lib/silcclient/protocol.c. Changed also the
2592 protocol specification about the public key authentication in
2593 the connection authentication protocol. The actual data to be
2594 signed is now computed with a hash function before signing.
2596 * Fixed the public key authentication from the server as well.
2597 Affected file silcd/protocol.c.
2599 * Removed the mlock()'s from the memory allocation routines.
2600 Affected file lib/silcutil/silcmemory.c. The ./configure does
2601 not check anymore for the mlock(). Affected file is
2604 * Fixed USERS command in server to allow the execution of the
2605 command for private and secret channels if the client sending
2606 the command is on the channel. Affected file silcd/command.c.
2608 * Fixed silc_client_get_clients_local to return the clients
2609 count correctly. It could return wrong value. Affected file
2610 lib/silcclient/idlist.c.
2612 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2615 types. The assembler optimizations seemed not to like 64-bit
2616 data types. The assmebler optimizations thus are now enabled
2617 also for BSD systems as opposed to only enable them for Linux.
2619 * Do not check for threads at all on BSD systems. Affected
2620 file configure.in.pre.
2622 * Removed -n and -h options from the Irssi SILC Client since
2623 they are not used in silc.
2625 * Fixed the prime generation to assure that the first digit
2626 of the generated random number is not zero since our conversion
2627 routines does not like number strings that starts with zero
2628 digit. If zero digit is seen the random number is regenerated.
2629 This caused some corrupted RSA keys when the zero first digit
2630 was met. Affected file lib/silcmath/silcprimegen.c.
2632 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Fixed WIN32 configuration in the ./configure script.
2635 Fixed to include xti.h on environments that has it.
2636 Patches by Carsten Ilchmann and andrew.
2638 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Changed the silc_id_create_client_id to be collision
2641 resistant. It is now assured that there cannot be created
2642 two same client ID's. I suspect that some weird bugs in
2643 the server were actually caused by duplicate Client IDs.
2644 Affected file silcd/serverid.[ch]. A router receiving
2645 new ID now also assures and informs the sending server
2646 if the ID caused collision.
2648 * Changed the silc_id_create_channel_id to also assure that
2649 there are no collisions.
2651 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * Statement about ignoring the Mutual Authentication flag when
2654 performing rekey with PFS was a bit misleading. It is ignored
2655 if it was set in the initial negotiation, it cannot be even
2656 set in the rekey. Fixed in the ke-auth draft. Started the
2657 new versions of the protocol drafts in the doc/.
2659 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Fixed a bug in silc_client_command_identify_save when saving
2662 new channel information. The channel name was no duplicated
2663 and caused crash on exit. Affected file is
2664 lib/silcclient/command_reply.c.
2666 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Fixed the getkey command handling in the server. Send just
2669 empty OK reply to the sender if the key could not be fetched
2670 (but everything else was ok, like the key just was not available).
2671 Changed the public key parameter to optional in the protocol
2672 specs so that empty OK reply can be sent. Affected file
2675 Added a message to Irssi SILC client to tell to user if the
2676 server did not return a public key.
2678 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Fixed a channel key regeneration bug. It registered new
2681 timeout tasks exponentially until all system resources were
2682 used. Affected file silcd/server.c.
2684 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Added the SILC Document generator to the scripts/silcdoc.
2687 It can be used to generate the Toolkit Reference Manual out
2688 of the source tree. Internally it will also use the RoboDoc
2689 generator now imported in util/robodoc.
2691 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Added couple of return's in rekey protocol if error orccurred
2694 during the protocol. The execution must be terminated.
2695 Affected file silcd/protocol.c. Also, terminate the protocol
2696 always with timeout.
2698 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * The client's Client ID was created initally from the wrong
2701 nickname (it could have been in format nick@host) in the
2702 silc_server_new_client. Affected file silcd/packet_receive.c
2704 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2706 * Added some SILC_LOG_ERROR's to various error conditions
2707 if client could not be added to ID cache. Affected files
2708 silcd/packet_receive.c and silcd/server.c.
2710 * When client's sock->user_data is freed, NULL also the
2711 client->router and client->connection pointers. Added check
2712 for these pointers being NULL to various places around the
2713 code. Affected file silcd/server.c.
2715 * Added client->data.registered == TRUE checks to various
2716 places around the code to assure that unregistered client's
2717 are not handled when it is not allowed. Affected file
2720 * Added `bool registered' fields to all
2721 silc_idlist_[server|client]_get_* routines to indicate whether
2722 the fetched client needs to be registered or not. Affected
2723 file silcd/idlist.[ch].
2725 * Add your own entry as registered to the ID cache in the
2726 server. Affected file server.c.
2728 * Fixed a bug in silc_server_new_server. The SilcServer was
2729 set as the new server's context instead of SilcServerEntry.
2730 This naturally caused some weird bugs.
2732 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Do not delete the channel rekey task when adding it
2735 for in silc_server_create_channel_key.
2737 * Changed the silc_server_create_channel_key to return
2738 TRUE or FALSE to indicate the success of the channel key
2741 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Fixed MSVC++ project files and added missing files to

2749 does not have it defined. Affected files are
2750 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2752 * Fixed buffer overflow from Irssi SILC Client. Affected
2753 file irssi/src/fe-common/core/themes.c.
2755 * Fixed double free in client library in the file
2756 lib/silcclient/client.c when disconnecting from server.
2758 * Applied double free patch from cras to Irssi SILC client.
2759 Affected files irssi/src/core/[modules/expandos].c
2761 * Fixed the disconnection handling to Irssi SILC Client.
2762 The application must call silc_client_close_connection
2763 in ops->connect client operation in case of failure of
2764 the connection. Affected file is
2765 irssi/src/silc/core/client_ops.c.
2767 * Do not set sock->protocol to NULL in the function
2768 silc_client_close_connection after executing the protocol's
2769 final callback since the sock might not be valid anymore.
2770 Affected file lib/silcclient/client.c.
2772 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Do not enable SILC_THREADS if the linking with libpthread
2775 did not happen. Affected file configure.in.pre.
2777 * Added notion to protocol specification that server must
2778 verify the sent authentication payload with CMODE when
2779 setting the channel founder key. Implemented it to the
2780 server. Affected file silcd/command.c.
2782 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2784 * Added _EXTRA_DIST SILC distribution variable to the
2785 distributions file. It is used to conditionally add extra
2786 files or directories to the specific distribution. Affected
2787 files ./prepare, Makefile.am.pre and distributions.
2789 Removed the `_' from the start of the distribution names.
2792 * Added README.WIN32 for instructions to compile the Toolkit
2795 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Fixed a double free in disconnection in the server. Affected
2798 file is silcd/server.c.
2800 * Fixed the lib/silcske/groups.c to work now also with GMP
2801 MP library. The string conversion did not work when using
2802 specific base and the base is indicated in the string as well.
2804 * Created win32/ directory which now includes MSVC++ specific
2805 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2806 It will appear only in the toolkit distribution
2808 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Changed the key material distribution function in case when
2811 the hash output is too short. The data is now concatenated
2812 a bit differently than it used to. Made the change to the
2813 SKE protocol specification.
2815 * Added better GMP detection to configure.in.pre. A patch
2818 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed a minor bug in SKE that might cause some problem on
2821 some platforms. Affected file lib/silcske/silcske.c.
2823 * Added the cookie checking for initiator in the SKE. It checks
2824 that the responder returns the sent cookie unmodified. The
2825 affected file is lib/silcske/silcske.c. Added new SKE
2826 error type INVALID_COOKIE that can be sent during the
2827 negotiation. Fixed some memory leaks as well.
2829 * Added the "invalid cookie" error message to Irssi SILC client's
2832 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Added `task_max' field to the SilcClientParams to indicate
2835 the maximum tasks the scheduler can handle. If set to zero,
2836 default values are used. Affected file lib/silcclient/silcapi.h.
2838 * Fixed memory leaks in silc_client_close_connection. Affected
2839 file lib/silcclient/client.c.
2841 * Added silc_client_del_client_entry to client library to free
2842 all memory of given client entry. Affected file is
2843 lib/silcclient/idlist.[ch].
2845 * Added new functions silc_client_del_channel and
2846 silc_client_del_server to delete channel and server entries.
2847 Affected file lib/silcclient/[silcapi.h/idlist.c].
2849 * Removed silc_client_del_client_by_id from silcapi.h.
2851 * Fixed the INFO command to return the server's own info
2852 correctly when querying by Server ID. Affected file is
2855 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Removed the non-blocking settings in WIN32 code in the
2858 silc_sock_[read/write] and added SleepEx instead. Affected
2859 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2860 of input data is now checked with FIONREAD and ioctlsocket.
2862 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Call silc_schedule_task_del_by_context in the
2865 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2866 Affected file lib/silccore/silcprotocol.c.
2868 * Call silc_protocol_cancel for active protocols in the
2869 silc_server_close_connection if the funtion
2870 silc_server_free_sock_user_data has not been called.
2871 Affected file silcd/server.c.
2873 * Generic tasks cannot be deleted using the del_by_fd
2874 task deleting function since generic tasks does not match
2875 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2877 * Added a notion to SILCOPER help file that the SILCOPER works
2878 only on router server, not on normal server.
2880 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Added for WIN32 support for the new scheduler as well.
2883 Affected file lib/silcutil/win32/silcwin32schedule.c.
2885 * Fixed the SHA1 implementation to work on various platforms.
2887 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2890 API. It is part of the scheduler now. Everything else is
2891 as previously but some functions has changed their names.
2892 Checkout the lib/silcutil/silcschedule.h for the interface.
2893 Updated all applications to use the new interface. Affected
2894 files are lib/silcutil/silcschedule.[ch].
2896 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Found a bug in the SKE implementation. The HASH value,
2899 specified by the protocol, was not computed correctly. The
2900 public key of the responder was not added to the computation
2901 even though it is mandatory. Affected file lib/silcske/silcske.c.
2902 This unfortunately causes incompatibilities with older
2903 clients and servers.
2905 * Added WIN32 specific network init and uninit functions:
2906 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2907 the Winsock2. Affected file lib/silcutil/silcnet.h and
2908 lib/silcutil/win32/silcwin32net.c.
2910 * Set the socket always to nonblocking mode on WIN32 after
2911 reading data or writing data. Affected file is
2912 lib/silcutil/win32/silcwin32sockconn.c.
2914 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Fixed various compilation problems under WIN32. Affected
2917 files lib/silcutil/win32/silcwin32thread.c and
2918 lib/silcutil/win32/silcwin32schedule.c.
2920 * Removed all _internal.h #includes from public header
2921 files. Internal headers must never be included from
2924 Removed also the lib/silcske/payload_internal.h file.
2926 * All include files that may be needed (public and some others
2927 included by the public headers) by application developers are
2928 now copied to the ./includes directory. It does not copy any
2929 internal headers. Affected file Makefile.defines.pre and all
2930 Makefile.am's under lib/ and subdirs.
2932 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Do not change the ~/.silc directory's permissions automatically.
2935 Affected file irssi/src/silc/core/clientutil.c.
2937 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Do not cancel the protocol in silc_server_close_connection
2940 it might cause recursion. Now cancelled in the function
2941 silc_server_free_sock_user_data. Affected file silcd/server.c.
2943 * Fixed the silc_server_remove_clients_by_server to regenerate
2944 the channel keys correctly finally. Added also new function
2945 silc_server_remove_clients_channels to actually do it.
2946 Affected file silcd/server.c.
2948 * Fixed the silc_server_new_channel to not crash by giving
2949 wrong router to the new channel. Affected file is
2950 silcd/packet_receive.c.
2952 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2955 which is given as argument to the silc_client_alloc now.
2956 It can be used to configure the client and set various parameters
2957 that affect the function of the client.
2959 * The USERS command in server did not check whether the channel
2960 is private or secret. Affected file silcd/command.c.
2962 * Added new argument to the USERS command in protocol specification.
2963 The USERS command now can take the channel name as argument
2964 as well. Added support for this in client and server and
2965 updated the protocol specs.
2967 * Completed the GETKEY command in client. It can be now used
2968 to fetch also servers public key not only some clients.
2969 Affected files lib/silcclient/command[_reply].c.
2971 * Added silc_client_get_server to return server entry by the
2972 server name. Affected files lib/silcclient/silcapi.h and
2975 * Redefined the IDENTIFY command in protocol specification to be
2976 more generic. It now can be used to query information about
2977 any entity in the SILC Network, including clients, servers and
2978 channels. The query may be based either the entity's name
2979 or the ID. Added support for this in both client and server.
2981 Affected files silcd/command.c and lib/silcclient/command.c
2982 and command_reply.c.
2984 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2985 the _from_client and _from_server functions. Affected file
2988 * Added silc_client_get_channel_by_id_resolve to the file
2989 lib/silcclient/silcapi.h to resolve channel information by
2990 its ID. Added also silc_client_get_channel_by_id that
2991 does not resolve it from the server.
2993 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Added SilcServerEntry context into the client library
2996 to represent one server. The INFO command now allocates
2997 these to save the resolved server info. For now on the
2998 client library will also keep information about servers,
2999 connected and resolved with INFO.
3001 The INFO command now allocates the SilcServerEntry context
3002 and saves the server info there. The COMMAND_REPLY in
3003 the INFO now returns the parameters to application in
3004 same order as defined in the protocol specification.
3006 The entries are cached in the client->server_cache.
3008 * The INFO command is now issued after received the Client ID
3009 from the server. Affected file lib/silcclient/client.c.
3011 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3012 to the application as the mode changer might be server.
3013 It is guaranteed that NULL is not returned anymore to the
3014 application. Affected file lib/silcclient/client_notify.c.
3016 The ID Type is now also passed to the application so that
3017 it can check whether the returned entry is SilcClientEntry
3020 Added new function silc_client_get_server_by_id to return
3021 the server entry by ID. Affected files are the
3022 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3024 * Do not create the channel in the Irssi SILC Client when issuing
3025 the JOIN command but when received the sucessful JOIN command
3026 reply. Otherwise the channel might get created even though we
3027 could not join it. The Affected file is
3028 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3030 * Fixed a channel joining bug in router. The router must also
3031 check the channel modes, invite and ban lists etc. when serving
3032 the JOIN command sent by normal server. Affected file is
3033 silcd/command.c. The router now resolves the client's
3034 information from the server who sent the JOIN command if it
3035 does not know it, and processes the JOIN command only after
3038 * Changed the SilcCommandCb to take new argument; void *context2.
3039 Affected file lib/silccore/silccommand.h
3041 The second argument in the command callbacks in the server now
3042 includes the SilcServerCommandReplyContext if the command was
3043 called as pending command callback from the command reply.
3044 Otherwise it is NULL. When called as pending the status of the
3045 command reply will be checked and if it was erronous the
3046 error will be sent to the original sender of the command.
3047 This way the client always receives the error messages even
3048 though the server was actually the one who received the error
3049 when it resent the command to router, for example. Affected
3050 files silcd/command[_reply].[ch].
3052 * Fixed sending WHOWAS command's error message to client if
3053 the requested client could not be found. It was missing.
3056 * Changed the CMODE and CUMODE commands reply arguments in the
3057 protocol specification. The Channel ID is now sent in both
3058 of the commands to identify the channel. Implemented this
3059 new feature to the client and server. Affected files
3060 lib/silcclient/command_reply.c and silcd/command.c.
3062 * Made better checks for invite and ban lists in the JOIN
3063 command in server. Affected file silcd/command.c.
3065 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * The server now performs the incoming host IP/DNS lookup
3068 using the silc_socket_host_lookup and thus does not block
3069 the server anymore. Affected file silcd/server.c.
3071 * Completed the multi-thread support for SILC Scheduler in
3072 the lib/silcutil/silcschedule.c.
3074 * Fixed the configure.in.pre to detect the pthread correctly
3077 * Fixed a deadlock in silc_task_queue_wakeup in the file
3078 lib/silcutil/silctask.c.
3080 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Added new function silc_schedule_wakeup that is used in
3083 multi-threaded environment to wakeup the main thread's
3084 schduler. It needs to be used when a thread adds a new task
3085 or removes a task from task queues. After waking up, the
3086 scheduler will detect the task queue changes. If threads
3087 support is not compiled in this function has no effect.
3088 Implemented the wakeup mechanism to both Unix and WIN32
3089 systems. Affected files are lib/silcutil/silcschedule.[ch],
3090 lib/silcutil/unix/silcunixschedule.c and the
3091 lib/silcutil/win32/silcwin32schedule.c.
3093 * Added new function silc_task_queue_wakeup to wakeup the
3094 scheduler by the specified task queue. Affected file
3095 lib/silcutil/silctask.[ch].
3097 * The silc_socket_host_lookup_start now wakes up the scheduler
3098 after adding the timeout task. Affected file is
3099 lib/silcutil/silcsockconn.c.
3101 * The silc_socket_host_lookup is synchronous now if the threads
3102 support is not compiled in. However, the callback is still
3103 called asyncronously through the scheduler, anyway. Affected
3104 file lib/silcutil/silcsockconn.c.
3106 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * Added new function silc_socket_host_lookup to perform
3109 asynchronous IP and FQDN lookups for the socket connection.
3110 Affected files lib/silcutil/silcsockconn.[ch].
3112 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3115 that may or may not compile the mutex support in.
3117 Changed the silc_mutex_alloc interface. It allocates the
3118 mutex now to the sent pointer and returns TRUE or FALSE.
3120 Affected file lib/silcutil/silcmutex.h.
3122 * Wrote the SILC Task Queue interface to support multi-threads.
3123 Affected file lib/silcutil/silctask.[ch].
3125 * Wrote the SILC Scheduler to support multi-threads. Affected
3126 file lib/silcutil/silcschedule.c.
3128 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3130 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3131 in lib/silcutil/win32/.
3133 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3135 * Defined SILC Mutex API and SILC Thread API and implemented
3136 them for Unix. Affected files are
3137 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3138 lib/silcutil/unix/silcunixmutex.c and
3139 lib/silcutil/unix/silcunixthread.c.
3141 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3143 * Fixed the silc_server_remove_clients_by_server's channel
3144 key re-generation. The hash table handling was incorrect
3145 and would not work with many channels. Affected file is
3148 * Fixed some memory leaks around the server code.
3150 * Rewrote the silc_server_get_users_on_channel to support IPv6
3151 based Client ID's. Affected file silcd/server.c.
3153 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3154 specification. However, a separate document must be written
3155 to define the detailed signing procedure and the payload
3156 associated with the flag. Defined the flag to the
3157 lib/silccore/silcchannel.h as well.
3159 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Changed the dynamic tables to static size tables in the
3162 lib/silccrypt/silchmac.c.
3164 * Removed GCC dependencies from the code. A patch by cras.
3166 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3168 * Do not show the error "Error receiving packet bla bla"
3169 in server if it really was not an error (-2 means that reading
3170 is pending). Affected file silcd/server.c.
3172 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Fixed a possible crash in silc_server_remove_clients_by_server
3175 in silcd/server.c. Fixed there also some memory leaks.
3177 * Fixed the silc_idlist_replace_client_id. It could replace
3178 wrong key in the hash table. Affected file silcd/idlist.c.
3180 * Do not check whether there are global users on the channel
3181 if the channel->global_users is FALSE. Affected functions
3182 silc_server_remove_from_one_channel and
3183 silc_server_remove_from_channels in silcd/server.c. Also,
3184 do not check if the removed client is local as we can be
3185 sure that global client was not removed from the channel
3186 and checking for global users is not needed.
3188 * The silc_server_remove_clients_by_server now re-generates
3189 the channel keys correctly for those channels that had
3190 clients removed from them. Affected file silcd/server.c.
3192 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Found the reason of random crashes in the server. We weren't
3195 ignoring the SIGPIPE signal (which can be sent in write())
3196 and it crashed the server. Affected file silcd/silcd.c.
3198 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Assure that sock->user_data is not NULL in the function
3201 silc_server_packet_send in silcd/packet_send.c.
3203 * Disconnect the remote connection if it could not be added
3204 to any ID lists in the server. The affected file is
3207 * Check in silc_server_packet_send[_real/dest] that the
3208 socket is not disconnecting and ignore the data if it is.
3209 Affected file silcd/packet_send.c.
3211 * Define inline to __inline on native WIN32 compilation.
3212 Affected file includes/silcwin32.h.
3214 * Added some explicit type casts for inline code since MSVC
3215 require them. Affected files lib/silcutil/silcbuffer.h,
3216 lib/trq/silcdlist.h and lib/trq/silclist.h.
3218 * Print warning in log files from now on if the packet
3219 decryption fails. Affected file silcd/server.c.
3221 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Changed the `say' client operation's interface to accept
3224 new `type' argument to indicate the type of the message sent
3225 by the library. The application may filter the library's
3226 messages according the type. The affected file is the
3227 lib/silcclient/silcapi.h.
3229 * Added two new functions to lib/silcclient/silcapi.h:
3230 silc_client_del_client and silc_client_del_client_by_id.
3231 Affected file lib/silcclient/idlist.c.
3233 * Moved the clientincludes.h from includes/ to silc/ and
3234 serverincludes.h from includes/ to silcd/.
3236 * The modes for the CMODE and CUMODE are now passed as
3237 uint32 for application with COMMAND_REPLY. The affected
3238 file is lib/silcclient/command_reply.c.
3240 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3242 * /WHOIS without arguments shows client's own information.
3243 Affected file lib/silcclient/command.c.
3245 * Changed PING to not accept any arguments. The specs
3246 says that client can ping only the connected server so
3247 requiring an argument is not needed. Affected file is
3248 lib/silcclient/command.c.
3250 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3252 * Fixed a fatal bug in private message sending and reception
3253 encryption and decryption when using private message keys.
3254 The implementation was incorrect and did not follow the
3255 specification. It causd that some of the message were
3256 lost since it did not use the sending and receiving keys
3257 as the protocol suggests. This has been fixed and will cause
3258 incompatibilities with older clients when sending private
3259 message encrypted with private message keys. Affected files
3260 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3261 and various other in Irssi SILC Client.
3263 Added `responder' boolean argument to the functions
3264 silc_client_add_private_message_key[_ske] to indicate when
3265 the key is added as responder or initiator of the key
3268 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Removed the silc_ske_check_version function and created
3271 a SilcSKECheckVersion callback. Added also a function
3272 silc_ske_set_callbacks that is now used to set all SKE
3273 callbacks. The callback functions are not given to
3274 the SKE functions anymore, but this function is used to
3277 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3279 * Added `silc_version' argument to the silc_client_alloc
3280 to define the version of the application for the library.
3281 The library will use the version string to compare it
3282 against the remote host's (usually a server) version
3283 string. Affected file lib/silcclient/silcapi.h
3285 * Added the KE protocol context to Key Agreement context
3286 in client library so that we can abort the SKE if it
3287 is in process when we get timeout. Affected file is
3288 lib/silcclient/client_keyagr.c.
3290 * Do not resolve the client ID forever if it returns in the
3291 first time that such client does not exist. This was done
3292 for example with private message. Affected file is
3293 lib/silcclient/client_prvmsg.c.
3295 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Do not add regex.h for WIN32. The affected file
3298 includes/silcincludes.h.
3300 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3301 not work yet 100%. It generates the DLL's automatically
3302 when compiling with --with-win32 under cygwin.
3304 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * lib/contrib/regex.c is not compiled on WIN32.
3308 * Added silc_net_get_socket_opt function to the
3309 lib/silcutil/silcnet.h.
3311 * Added includes/silcwin32.h for WIN32 specific includes
3314 * Do not use ptime structure or any of the posix process
3315 functions on WIN32 in lib/silccrypt/silrng.c.
3317 * Added silc_gettimeofday to provide generic function
3318 for struct timeval on all platforms. Added the function
3319 to lib/silcutil/silcutil.h.
3321 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3323 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3324 library as they clearly belong there. As a plus side we
3325 can make the actual socket connection routines platform
3328 Added also new generic function silc_socket_read and
3329 silc_socket_write (that used to be silc_packet_[read/write].
3330 The implementation of these are platform specific.
3332 * Added WIN32 specific routines of silc_socket_[read/write]
3333 to lib/silcutil/win32/silcwin32sockconn.c.
3335 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * Added preliminary support for native WIN32 compilation under
3338 cygwin (using the -mno-cygwin option for GCC) to the
3339 ./configure.in.pre. The --with-win32 now prepares the
3340 compilation for native WIN32.
3342 * Rewrote the SILC Scheduler interface in the file
3343 lib/silcutil/silcschedule.h. The scheduler is now context
3344 based and does not have anymore any global static scheduler.
3345 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3346 and created lib/silcutil/win32 directory for WIN32 based
3349 * Added Unix specific network routines to the
3350 lib/silcutil/unix/silcunixnet.c and the old
3351 lib/silcutil/silcnet.c includes now only generic routines.
3353 Added WIN32 specific network routines to the
3354 lib/silcutil/win32/silcwin32net.c.
3356 * Added Unix specific utility functions from the
3357 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3359 * Added WIN32 SILC Scheduler to the file
3360 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3363 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * Do not handle JOIN notify in the server if the target client
3366 is not registered (idata->registered == FALSE). The affected
3367 file is silcd/packet_receive.c.
3369 * Update the nickrec->founder in event_cumode in the Irssi SILC
3370 client. Affected file irssi/src/silc/core/silc-channels.c.
3372 * Fixed the CUMODE_CHANGE notify handling in the server when
3373 server and router are announcing their clients on channels.
3374 Now the mode changes are saved and notified correctly. The
3375 affected file is /silcd/packet_receive.c.
3377 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3378 They really did not replace the cache entry in the ID Cache.
3379 Now they do that. Affected file silcd/idlist.c.
3381 * Fixed the KICK notify handling in the Irssi SILC client to
3382 update the channel records so that the kicked client does not
3383 appear to be on the channel. The affected file is
3384 irssi/src/silc/core/silc-channels.c.
3386 * Always update the conn->current_channel when executing command
3387 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3389 * Fixed the KILL notify handling in Irssi SILC client to remove
3390 the killed client on all channels.
3392 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Fixed the silc_parse_command_line to remove extra spaces
3395 from the start and end of the arguments. Affected file is
3396 lib/silcutil/silcutil.c.
3398 * Cancel and free any active protocol in the function
3399 silc_server_close_connection. Affected file silcd/server.c.
3401 * Cancel and free any active protocol in the function
3402 silc_client_close_connction. Affected file is
3403 lib/silcclient/client.c.
3405 * Do not execute the KILL command for clients that are in
3406 history (ie. they are not in the network). Affected file is
3409 * Fixed KILL notify handling, client does not crash anymore.
3410 Affected file irssi/src/silc/core/silc-channels.c.
3412 * Reduced the default packet buffer size from 2048 to 1024 in
3413 lib/silccore/silcpacket.c.
3415 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3416 counter to the SKE context that is incresed when the SKE library
3417 performs async operation outside the library. If the outside
3418 process frees the SKE context and FREED status will be set
3419 and the library will detect after the sync operation that the
3420 libary is freed. The affected files are
3421 lib/silcske/silcske[_status].[ch].
3423 * Resolve the client entry information in the function
3424 silc_client_channel_message to assure that NULL pointer is not
3425 passed as client entry to the application. */
3427 * Fixed the task timeout calculation to assure that there is
3428 never negative timeouts. The affected file is
3429 lib/silcutil/silcschedule.c.
3431 * Fixed the channel user mode notification sending in server.
3432 It was sent point-to-point to the router (or to server by router)
3433 but it needs to be destined to a channel. The routines now
3434 supports sending the channel user mode notifys to the channels
3435 when announcing clients and channels. Affected files are
3436 silcd/server.c and silcd/packet_receive.c.
3438 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3439 It did not actually replace the old channel entry in the cache.
3440 Affected file lib/silcclient/client_notify.c.
3442 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Fixed a possible crash in silc_packet_send_prepare. It now
3445 assures always that there is enough space in the buffer and
3446 at the tail area of the buffer (for MAC).
3448 Fixed the inbound buffer reallocation in silc_packet_read.
3449 It was old code and did not handle the reallocation correctly.
3452 The affected file is lib/silccore/silcpacket.c.
3454 * Fixed buffer overflow in silc_parse_nickname in the file
3455 lib/silcutil/silcutil.c.
3457 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * make install generates new server keys only if there is not
3462 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3465 Added check that if the NOREPLY is set then we will not send
3466 the away message. This avoids infinite loop of away messages
3467 if both clients are away. The affected file is
3468 lib/silcclient/client_prvmsg.c.
3470 * Fixed client crash if /NICK was given without arguments.
3471 Affected file lib/silcclient/command.c.
3473 * Server does not send the invite list in INVITE command back
3474 to the client if the list was not altered. Added this notion
3475 to the protocol spec as well. Affected file silcd/command.c.
3477 Fixed possible crash in INVITE command by checking the
3478 value of silc_server_get_client_route command.
3480 * Fixed the INVITE notify type handling. The arguments are now
3481 taken in correct order and client does not crash. The affected
3482 file is irssi/src/silc/core/silc-channels.c.
3484 Removed the "Inviting xxx to channel" message from the
3485 client library away and let the application handle it.
3486 Affected file lib/silcclient/command.c. Added that message
3487 to Irssi SILC client's message formats.
3489 * Fixed CMODE command crash in client. It now checks the
3490 amount of arguments correctly and does not crash. The affected
3491 file is lib/silcclient/command.c.
3493 * Do not create new channel automatically in silc_channels_join
3494 but check whether the channel by that name already exists.
3495 Affected file irssi/silc/core/silc-channels.c.
3497 * Do not send the SERVER_SIGNOFF to router if the disconnected
3498 entity was the router. Affected file silcd/server.c.
3500 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3501 SILC client as it was missing from there.
3503 Added the handling of the KICK notify to the Irssi SILC client
3504 as it was missing. Added "you have been kicked" message to
3505 Irssi SILC client's message modules formats.
3507 Added the handing of the KILL notify to the Irssi SILC client
3508 as it was missing. Added the kill message module formats
3511 The affected file is irssi/src/silc/core/silc-channels.c.
3513 * The router did not save the channel mode the server announced.
3514 Affected file silcd/packet_receive.c.
3516 * Fixed a possible crash in INFO command in server. If the
3517 server did not provide the server info it crashed. Affected
3518 file silcd/command.c.
3520 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Fixed the GETKEY command in the server to check also the
3523 global list. Otherwise the GETKEY would not work correctly
3524 in normal SILC server. Affected file silcd/command.c.
3526 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Fixed GETKEY crash, it crashed if the command did not succseed.
3530 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3533 is now real and not just an macro interface to GMP.
3535 Removed the entire GMP from the source tree and imported new
3536 NSS MPI library instead. Reason for removing GMP is that it is
3537 extremely large and compiles extremely slow. The NSS MPI
3538 is only a few files and compiles in less than 10 seconds.
3539 The speed is also about the same as GMP. The MPI is imported
3540 to lib/silcmath/mpi.
3542 If the system has GMP installed we will still use the GMP.
3543 If it is not then the NSS MPI will be compiled.
3545 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Merged a long nickname (127 characters long) crash bugfix from
3548 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3550 * Merged a freed memory reference bugfix from Irssi CVS tree.
3551 Affected file irssi/src/core/commands.c.
3553 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added the server's public key sving and verification to the
3556 server when performing the SKE. This was missing and the
3557 remote server's (or router's) public key was accepted without
3558 checking whether we have it previously or trust it at all.
3559 Affected file silcd/protocol.c.
3561 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Check in the silc_server_timeout_remote if protocol is active
3564 and make sure that the protocol's final callback is called so
3565 that all memory if freed. Affected file silcd/server.c.
3567 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * silc_server_whois_send_reply crashed the server if the nickname
3570 was 127 characters long. Affected file silcd/command.c.
3572 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Added sanity check to the silc_server_new_client. If the hostname
3575 is provided inside username then check that the provided hostname
3576 really is the same as the resolved one. If the hostname was not
3577 resolved then check it from the public key. Affected file is
3578 silcd/packet_receive.c.
3580 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3581 if the server disconnected us and the connection is not valid
3582 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3584 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3585 the library to the lib/silcutil/silcutil.[ch].
3587 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Close log file after open. Affected file
3590 lib/silcutil/silclog.c.
3592 * Check whether sock == NULL in silc_client_send_packet and return
3593 if it is. Affected file lib/silcclient/silcclient.c.
3595 * Check rec->entry == NULL in the Irssi SILC Client before
3596 sending the channel message. Affecte file is
3597 irssi/src/silc/core/silc-servers.c.
3599 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Merged a splitted window bugfix from Irssi CVS tree. The
3602 affected file is irssi/src/fe-text/textbuffer-view.c.
3604 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3605 It did not print nickname.
3607 * Improved the distributions system a bit.
3609 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3612 irssi/src/fe-text/gui-window.c.
3614 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3615 to in-active server. The affected file is
3616 irssi/src/silc/core/client_ops.c.
3618 * Resolve the client in USERS command reply if the entry does
3619 not have username resolved. The affected file is
3620 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3621 command to WHOIS command to really resolve stuff. The USERS
3622 is not used any more in any critical section so WHOIS can
3623 be used even though it might be slower than IDENTIFY.
3625 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3628 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Changed the protocol API a bit more consistent in the
3631 lib/silccore/silcprotocol.[ch].
3633 * Changed the following headers to ROBODoc format:
3635 lib/silccore/silcpayload.h
3636 lib/silccore/silcprotocol.h
3637 lib/silccore/silcsockconn.h
3639 All core library headers are now formatted.
3641 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Fixed a bug in Irssi SILC client; do not show that you are
3644 server/router operator if you really are not. Affected file is
3645 irssi/src/silc/core/client_ops.c.
3647 * Renamed silc_command_free_payload to silc_command_payload_free.
3648 Affected file lib/silccore/silccommand.h
3650 * Added silcmath.h to include the prototoypes of various routines
3651 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3654 * Changed the following headers to ROBODoc format:
3656 lib/silccore/silcchannel.h
3657 lib/silccore/silccommand.h
3658 lib/silccore/silcid.h
3659 lib/silccore/silcidcache.h
3660 lib/silccore/silcmode.h
3661 lib/silccore/silcnotify.h
3662 lib/silccore/silcpacket.h
3663 lib/silcmath/silcmath.h
3665 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Added checking to the server code not to start the server if
3668 ciphers and stuff are not configured properly. Affected files
3669 silcd/serverconfig.[h] and silcd/server.c.
3671 * Changed the layout of the header files of the public interfaces
3672 in the SILC libraries. The new layout supports ROBODoc
3673 documentation tool (and some others) so that it is easy to create
3674 a library reference manual. All the other headers and source
3675 code must still follow the CodingStyle document. Also source
3676 code must not include these ROBODoc stuffs, only the headers.
3677 Furthermore, all public interface headers must now be named
3678 by using `silc' prefix, example: silcapi.h, silccipher.h.
3679 Some files were renamed due to this. All the other headers
3680 must not be used as public interfaces. I will update the
3681 CodingStyle document later. Changed following headers, so far:
3683 lib/silcclient/silcapi.h
3684 lib/silccore/silcauth.h
3685 lib/silccore/silcprivate.h
3686 lib/silccrypt/silcdh.h
3688 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Removed silc_client_packet_send_flush from the client library
3693 as it is not needed. Affected file lib/silcclient/client.[ch].
3695 * Added printing of message of unresolved authentication method
3696 to the Irssi SILC client. Added it to the module formats.
3697 Removed the same message from the client library.
3699 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Added new distribution feature, DISTLABEL. Every distribution
3702 can define own preprocessor label that can be used in the
3703 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3704 file distributions, acconfig.h.pre and prepare.
3706 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added Makefile.defines_int to include the actual definitions
3709 for Makefile.defines.in. Tested the new distribution system,
3710 created distributions and tested installation.
3712 * Added AWAY message printing to the Irssi SILC client. Added
3713 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3715 * Added SCONNECT command to call the SILC's CONNECT command.
3716 Cannot use CONNECT directly since Irssi uses that internally.
3717 Affected file irssi/src/silc/core/silc-servers.c.
3719 Added ACTION local command. It is same as ME command but takes
3720 the channel as mandatory argument.
3722 Rewrote some of the Irssi's help files to suite for SILC
3725 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Added Makefile.defines[.in] that should for now on be included
3728 in all Makefile.am file in the source tree. That file includes
3729 all common compilation definitions for SILC source tree.
3731 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Minor changes to the ./prepare script to change the package
3734 name according the distribution name to the configure.in.
3736 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Created new distribution system. Added file `distributions'
3739 that defines all the distributions that can be created out of
3740 the SILC source tree. The ./prepare script now reads that
3741 file to determine how to prepare the distributions. The
3742 first argument to the ./prepare is the name of the distribution
3743 and second is the version of the distribution. If given
3744 without arguments it creates the default (toolkit) distribution
3745 with the default version (defined in ./prepare).
3747 All Makefile.am files that are subject to the distributions
3748 are now named as Makefile.am.pre. These are ./Makefile.am
3749 and lib/Makefile.am. Others may be changed later.
3751 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Added invite list, ban list, some key management and connection
3754 error message printing to module formats in the Irssi SILC client.
3756 * Added new silc_client_set_away_message to set the away message
3757 that is back to the person who sent private message. The
3758 affected file lib/silcclient/silcapi.h and the
3759 lib/silcclient/client_prvmsg.c.
3761 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed the private message sending in the Irssi SILC client,
3764 added local command KEY to the Irssi SILC client.
3766 Added key management and key agreement message formats to the
3767 irssi/src/fe-common/silc/module-formats.[ch].
3769 Added USERS (alias WHO) printing, server/router operator
3770 indication and LIST command printing to the module formats.
3772 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Fixed channel joining notify handling, cumode notify handling
3775 from Irssi SILC client.
3777 * Added SILC specific module-formats to the Irssi SILC client so
3778 that SILC specific message hilighting, colors etc is possible.
3779 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3781 Added channel mode, channel user mode, actions, notices,
3782 whois and whowas printing to the the module-formats.c.
3784 * Fixed a bug in channel deletion in the server. The channel
3785 is not left to the cache even if the channel founder auth mode
3786 is set when there are no users anymore on the channel. Affected
3787 file silcd/server.c.
3789 * The silc_net_localhost now resolves the entire hostname including
3790 the domain name. Affected file lib/silcutil/silcnet.c.
3792 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Changed the ask_passphrase client operation to be ascynchronous.
3795 It has now a completion callback and a context that the
3796 application must call after it has got the passphrase from
3797 the user. Affected files lib/silcclient/silcapi.h,
3798 lib/silcclient/protocol.c, lib/silcclient/command.c and
3801 Added SilcAskPassphrase callback that the application calls
3802 to deliver the passphrase to the library.
3804 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3805 The public key verification and especially a certificate
3806 verification is asynchronous procedure.
3808 Added new SILC_SKE_STATUS_PENDING status to indicate the
3809 request is pending and a callback will be called to finalize
3812 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3813 indicate that remote end did not send its public key (or
3814 certificate), even though we require it. Added check for this
3815 condition in the SKE. This was a security bug, now fixed.
3817 Defined new SilcSKEVerifyCbCompletion callback that is called
3818 when the verification process is completed.
3820 The affected files lib/silcske/silcske_status.h and
3821 lib/silcske/silcske.[ch].
3823 * Changed the verify_public_key client operation to be async
3824 as well. Defined SilcVerifyPublicKey callback that is used to
3825 indicate the success of the public key verification process.
3827 Changed the server and client to use the new async client
3830 * Changed the Irssi SILC client's internal scheduler to be called
3831 twice as many times as it used to be. As a result the client
3832 should be a bit faster now. Affected file is
3833 irssi/src/silc/core/silc-core.c.
3835 * Added support to Irssi SILC client of asynchronous public key
3836 verification and passphrase inquiry. Affected file is
3837 irssi/src/silc/core/silc-core.c.
3839 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Do not say "You have left channel %s" in client library.
3842 Moved it to the application. Affected files are
3843 lib/silcclient/command.c and silc/client_ops.c.
3845 * Fixed silc_client_get_clients. Command context was not
3846 duplicated and was freed memory in the callback. Affected
3847 file lib/silcclient/idlist.c.
3849 * Do not say "you are now talking..." on JOIN command in the
3850 client library. The appliation must handle it.
3852 * Do not say ".. changed topic to" in command reply in the
3853 client libary. The application must handle it.
3855 * Fixed TOPIC command sending in the client library.
3857 * Fixed a memory leak in silc_client_command_free in the file
3858 lib/silcclient/command.c.
3860 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Imported a modified version of Irssi client to the source tree.
3863 The Irssi will be used to create a new client called
3864 Irssi SILC. Imported to irssi/.
3866 Added silc_core_init_finish function to the Irssi. Affected
3867 file irssi/configure.in.
3869 A lot changes in the Makefile.ams around the irssi tree.
3871 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Do not rehash if the new size is same as the old size of the
3874 hash table, in the silc_hash_table_rehash*. The affected file
3875 lib/silcutil/silchashtable.c.
3877 * Replaced hash_table_del_by_context calls from the server
3878 (when channel->user_list and client->channels) to the
3879 hash_table_del as it is sufficient and faster.
3881 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Added silc_hash_table_list, silc_hash_table_get and the
3884 SilcHashTableList structure to provide an alternative way to
3885 traverse the hash table. The affected files are
3886 lib/silcutil/silchashtable.[ch].
3888 * Changed the server's idlist routines to use the hash table
3889 routines to optimize the code.
3891 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Replaced the client entry's `channel' list and channel entry's
3894 `user_list' list to hash tables for optimized lookup. Changed
3895 the code to use the hash table interface around the code.
3896 Affected file lib/silcd/idlist.[ch].
3898 * Added `auto_rehash' boolean argument to the function
3899 silc_hash_table_alloc to indicate whether the hash table should
3900 auto-rehash when it thinks is appropriate time. It will
3901 increase the hash table size if the there is twice as much
3902 entries in the table than the size of the table, and will
3903 decrease the size if there are twice as less entries than
3904 the size of the table.
3906 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3910 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * silc_idcache_purge_by_context deletes the entry now by context
3913 as it is supposed to do. Affected file lib/silccore/idcache.c.
3915 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3916 client is not anymore valid (WHOWAS givens the info) and not
3917 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3919 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Removed the `data' and `data_len' arguments from the ID Cache
3922 interfaces and added `name' argument. ID Cache does not handle
3923 anymore the binary data only a names associated with given ID.
3925 * When hashing a Client ID with silc_hash_id the entire ID is
3926 not hashed anymore, instead only the hash of the Client ID is
3927 hashed. This way we can access the Client ID from the cache
3928 with Client ID but with the hash of the ID (which is a hash of
3929 the nickname) as well without any difference in performance.
3931 Added also silc_idcache_find_by_id_one_ext to do one on one
3932 searching when we have the actual ID. Added also function
3933 silc_hash_client_id_compare. The affected files are
3934 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3936 * When hashing the name associated with a ID it is always done
3937 in lowercase. This way we can access the cache without worrying
3938 about case-sensitivity, even though, for example nicknames are
3941 * Fixed a bug in server with channel message sending. It put
3942 wrong ID type as destination ID. The affected file
3943 silcd/packet_send.c.
3945 * silc_idcache_del_by_context now deletes from all hash tables
3946 by context. Affected file lib/silccore/idcache.c.
3948 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Changed the client library to use the new ID Cache interface.
3951 Changes around the source tree.
3953 * Added silc_hash_table_rehash_ext to rehash with specific
3954 hash function. Affected file lib/silcutil/silchashtable.[ch].
3956 * Added silc_hash_string_compare to compare two strings in the
3957 hash table. Affected file lib/silcutil/silcutil.[ch].
3959 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Added new function silc_idcache_del_by_context into the
3962 lib/silccore/idcache.[ch].
3964 * Changed the server's ID list routines to use the new ID Cache
3965 interface. Changes around the source tree.
3967 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Added silc_hash_table_del[_by_context]_ext functions in to the
3970 lib/silcutil/silchashtable.[ch].
3972 Removed silc_hash_table_find_all* routines and added new
3973 silc_hash_table_find_foreach to replace them.
3975 Added silc_hash_table_replace_ext function as extended
3976 replacing function. Separated the simple hash table interface
3977 from the extended hash table interface in the file
3978 lib/silcutil/silchashtable.h.
3980 * Fixed minor bugs and changed it to use some of the new
3981 hash table functions in lib/silccore/idcache.c
3983 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Added new function silc_hash_table_find_all to return all keys
3986 in the hash table by the specified key. As the hash table is
3987 collision resistant it also makes it possible to have several
3988 duplicate keys in the hash table. This function may be used to
3989 find all of the keys from the hash.
3991 Added user_context arguments to the SilcHashFunction,
3992 SilcHashCompare and SilcHashDestructor to deliver user specified
3995 Added new fuctions silc_hash_table_find[_all]_ext to do
3996 extended lookup with specified hash and compare functions and
3997 specified user contexts.
3999 Added new function silc_hash_table_add_ext to add the key
4000 with specified hash function and user context.
4002 Added new function silc_hash_table_foreach to traverse all
4003 entrys in the hash table. Added SilcHashForeach callback
4006 Added new function silc_hash_table_del_by_context to delete
4007 the entry only if the context associated with the key matches.
4009 Affected files are lib/silcutil/silchashtable.[ch].
4011 * Removed silc_hash_[server/client/channel]_id and added just
4012 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4013 silc_hash_id_compare to compare two ID's using as the hash table
4014 comparison function. Added also silc_hash_data to hash
4015 binary data and silc_hash_data_compare to compare it.
4017 * Removed silc_idlist_find_client_by_hash as it is not needed
4018 anymore. Affected file silcd/idlist.[ch].
4020 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4021 to use internally the SilcHashTable. The new ID Cache is a lot
4022 faster than the old one. Some of the ID Cache interface was also
4023 rewritten and obsolete and stupid functions were removed.
4025 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Added entry_count field to the SilcHashTable to keep the number
4028 of the entries in the table. Implemented the function
4029 silc_hash_table_rehash. Added new function
4030 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4032 Fixed a minor bug in silc_hash_table_free.
4034 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4035 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4036 into the lib/silcutil/silcutil.[ch].
4038 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Implemented a collision resistant hash table into the
4041 lib/silcutil/silchashtable[ch]. See the header and the source
4042 for the SilcHashTable API.
4044 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Merged dotconf version 1.0.2 into lib/dotconf.
4048 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Do not compile anything in lib/silcsim/* if the SIM support
4051 is not enabled. The tree should now compile without problems
4054 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Compiled the SILC under cygwin. Compiled and tested briefly
4057 without problems. More tests needed. The SIMs didn't compile
4060 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4062 * Fixed possible crash in silc_get_username in the
4063 lib/silcutil/silcutil.c.
4065 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Fixed a va_arg in silc/client_ops.c.
4069 * Oops, RC5 routines were named AES and caused some problems
4070 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4072 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Added new SilcIDIP structure into the lib/silccore/id.h and
4075 replaced the old `ip' fields from all SILC ID's to that type.
4076 This is a step towards IPv6 support.
4078 The silc_id_get_len takes now the ID as an extra argument.
4079 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4080 both IPv4 and IPv6 based ID's.
4082 The affected files are lib/silccore/id.[ch] and other files
4083 around the tree using these routines.
4085 * Removed the ID length arguments in server from various
4086 silc_server_send_notify_* routines -> they are not needed
4089 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Fixed memory leak in silc_encode_pem_file in the file
4092 lib/silcutil/silcutil.c.
4094 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Check minor version as well in the SKE. Affected files are
4097 silcd/protocol.c and lib/silcclient/protocol.c.
4099 * Added --identifier option to the server so that an identifier
4100 can be when creating the public key for the server. Affected
4101 file is silcd/silcd.c.
4103 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4104 lib/silccrypt/silcpkcs.c.
4106 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Register default ciphers and stuff when using -C option with
4109 the server. Affected file sildc/silcd.c.
4111 * Put back the servers public key filename format, it is better
4112 than the new one. For now, the client keys are saved with the
4113 new filename format. The affected file silc/client_ops.c.
4115 * Implemented the Cipher API for the rest of the ciphers that
4116 did not implement it or implemented it the wrong way.
4118 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Register default ciphers and stuff when using the -S option
4121 in the client. Affected file silc/silc.c. Same also when
4122 creating new key pair with -C option.
4124 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4126 * Fixed the silc_verify_public_key client operation function to
4127 save the public keys differently. The fingerprint is now
4128 used as filename and not the hostname. This way also the
4129 client keys are saved uniquely and not with hostnames. The
4130 affected file is silc/client_ops.c.
4132 * Trimmed the silc_hash_fingerprint function to remove extra
4133 whitespaces from the end of the fingerprint. The affected
4134 file is lib/silccrypt/silchash.c.
4138 * Added silc_cipher_register_default function to register all
4139 default ciphers. It can be used when configuration files
4140 does not exist and the application does not want any specific
4141 ciphers in any specific order.
4143 The SilcDList is now used as silc_cipher_list dynamically
4144 allocated cipher list. Removed the static list all together
4145 and now all ciphers must be allocated to the dynamic list.
4146 The silc_cipher_alloc routine was changed to check only the
4149 All silc_cipher_* routines that used to return int returns
4152 The affected files lib/silccrypt/silccrypt.[ch].
4154 * The same thing was done to silc_hash_* as for silc_cipher_*
4155 routines. Affected files lib/silccrypt/silchash.[ch].
4157 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4158 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4159 Added also silc_pkcs_[un]register[_default] functions.
4160 Removed the data_context from the PKCS API.
4162 * Added silc_hmac_register_default function to register default
4163 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4164 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4165 to unregister all hmacs at once.
4167 * Register the default ciphers, hash functions, PKCSs and HMACs
4168 if client's configuration file does not exist. The affected
4171 * The client did not load the hash functions from the SIM
4172 modules at all. Added support for this. Affected file is
4173 silc/clientconfig.c.
4175 * When decoding public key with silc_pkcs_public_key_decode, check
4176 the supported algorithm only if PKCS are registered. Affected
4177 file lib/silccrypt/silcpkcs.c. The same was done with the
4178 silc_pkcs_private_key_decode.
4180 * Fixed the SILC List routines to keep the list always in order.
4181 It used to change the list's order when traversing the list but
4182 not it preserves the order. Affected file lib/trq/silclist.h.
4184 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added the client library to use the SilcSocketConnection's
4187 reference counter (by silc_socket_dup) to prevent the bug that
4188 the socket object may be freed underneath async operation.
4190 * The name resolv library checking fixes in the configure.in.pre.
4193 * Created new version of the protocol drafts for future
4194 development. The -03 drafts are the ones that will be changed
4195 in the trunk now and the -02 will remain as they are.
4197 * Send list of CUMODE notifys to the router when announcing
4198 the channel users to the router. Affected file silcd/server.c.
4199 If the router receiving channel founder CUMODE for a channel
4200 that already has channel founder it will send CUMODE notify
4201 to the sender to remove the channel founder rights from the
4202 announced client. Affected file silcd/packet_receive.c.
4204 * The CUMODE notify may now use Server ID as well as the entity
4205 who changes the mode. Updated protocool specs.
4207 * Updated INSTALL and README files.
4209 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * New web pages in the http://silc.pspt.fi. The pages was
4216 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Implemented the [DenyConnectin] config section in the server.
4219 Added silc_server_config_denied_conn to check whether incoming
4220 connection is denied. Affected file silcd/serverconfig.[ch].
4222 * Do not check the ports when checking the incoming configuration
4223 data if the port is 0, meaning any. Affected file is
4224 silcd/serverconfig.c.
4226 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Fixed buffer overflow in silc_string_compare in the file
4229 lib/silcutil/silcutil.c.
4231 * Fixed double free in silc_server_command_leave in the file
4234 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Fixed the version checking in the server. Affected file is
4239 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Fixed the configuration data fetching when accepting new
4242 connections in the server. Affected file silcd/server.c.
4244 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4246 * Added `sender_entry' argument to the function
4247 silc_server_packet_relay_to_channel so that we can check
4248 whether some destination actually belongs to the same route
4249 the sender belongs (ie, we must not resend the packet to the
4250 sender). Affected file silcd/packet_send.[ch].
4252 * Added `servername' field to the SilcClientEntry in the server
4253 to hold the name of the server where client is from. Affected
4254 file is silcd/idlist.h.
4256 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Moved the channel message encrypting in the router betwen
4259 router connections from silc_server_channel_message to the
4260 silc_server_packet_relay_to_channel since we want to check
4261 whether we have anybody channel before encrypting anything.
4262 Affected files silcd/packet_[receive/send].c.
4264 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Fixed the [AdminConnection] server config section to support
4267 multiple entries. Affected file silcd/serverconfig.c.
4269 * Added support into the server to check the validity of the
4270 incoming connection before executing any KE or authentication
4273 * The connection configuration is now saved to the KE and
4274 connection auth protocol contexts and not fetched anymore in
4275 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4277 * The local hosts listenning address and port is also resolved
4278 now when starting the server. We want to have the socket object
4279 to include the real address and port for the listener. Added
4280 new function silc_net_check_local_by_sock into the files
4281 lib/silcutil/silcnet.[ch].
4283 * Fixed a broadcast bug in server -> do not broadcast if we
4286 * Fixed a routing bug. Do not route broadcast packets ever.
4287 Broadcast packets must be processed always and not routed since
4288 they may be destined to some other host than yourself and thus
4289 would get routed without no good reason. Affected file is
4292 * Added function silc_server_config_is_primary_route to check
4293 whether primary router connection has been configured (a router
4294 configuration that we are initiating). If there is not, we
4295 will assume that there is only two routers in the SILC network
4296 and we will use the incoming router connection as our primary
4297 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4299 * Changed the order of the broadcasting. Broadcast _after_ the
4300 packet has been processed not before. Affected file is
4303 * Fixed a [ClientConnection] parsing bug. The port was never
4304 parsed correctly thus resulting to port 0. Affected file
4305 silcd/serverconfig.c.
4307 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4308 argument and did not set the broadcast packet flag. Affected
4309 file silcd/packet_send.c. Fixed same bug in the function
4310 silc_server_send_notify as well.
4312 * If we receive NEW_ID packet for our own ID in the server, ignore
4315 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Removed the nickname from the Private Message Payload.
4320 Updated the code and the protocol specs.
4322 * Updated protocol specs for submitting to the IETF.
4324 * Tweaked the Random Number Generator a bit. Affected file
4325 lib/silccrypt/silcrng.c. Exported a new function
4326 silc_rng_[global]_add_noise which can be used to add more
4329 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Do not parse packets with different timeout when protocol
4332 is active -> may cause problem with rekey. Affected file
4335 * When server receives signoff notify it must not create
4336 new channel key if the client is on any channels since the
4337 sender of the signoff notify will create it.
4339 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added printing of error messages during SKE protocol from the
4342 failure packet sent by server during SKE. Affected file
4345 * Removed the client's failure_callback handling with timeout
4346 and handle it immediately when received.
4348 * The SKE library returned wrong type in SUCCESS and FAILURE
4349 packets. They must be 32 bit MSB not 16 bit MSB.
4351 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Ok, rewrote the logic of the re-key and now it seems to work.
4354 I tested it on high traffic with frequent re-keys without
4355 problems. Added hmac_receive (and renamed hmac to hmac_send)
4356 in SilcClientConnection in lib/silcclient/client.h and
4357 in SilcIDListData in silcd/idlist.h. Also, removed the
4358 SilcPacketParserContext's cipher and hmac fields as they are
4359 not needed anymore and actually caused some problems when
4360 the ciphers and hmac's changed underneath the packet parser.
4362 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * If re-key protocol is active then process the incoming packets
4365 synchronously since we must assure that icoming packets encrypted
4366 with the old key is processed before the new keys is set to
4367 use. This is true other packets than for REKEY packets.
4368 Affected file silcd/server.c. The same was done to client library
4369 as well, affected file lib/silcclient/client.c.
4371 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Fixed bug in client and server to accept the force send if
4374 the packet is send from silc_[server/client]_packet_process
4375 function. Otherwise the packets are never delivered, oops.
4377 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Disable force sending of packets when REKEY protocol is active.
4380 We must assure that no packet is sent directly when rekey is
4381 performed. All packets must be sent through packet queue.
4382 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4383 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4384 function is silc_[server/client]_packet_send_real to check
4387 * Replaced the SIM paths from example config files to
4388 /usr/local/modules. Also, make install creates now
4389 /usr/local/silc/logs directory to hold all the SILC server
4392 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Made the configure.in.pre work on Solaris. Patch by salo.
4396 * Made all ciphers compatible with non-x86 machines. Defined
4397 CBC mode macros into lib/silccrypt/ciphers_def.h.
4399 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Fixed the make install.
4403 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * When MAC computation fails the silc_packet_decrypt returned 0
4406 even though it was supposed to return -1. Fixed this. The
4407 affected file is lib/silccore/silcpacket.c.
4409 * Do not replace the config files in /etc/silc (in make install)
4410 if they already exist. Affected file ./Makefile.am.
4412 * Do not send re-key packets immediately but through packet queue.
4413 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4415 * Changed silc_net_check_host_by_sock to return FALSE if the
4416 IP/DNS could not be resolved. Though, it returns the IP address
4417 now even if it could not resolve it (but returns also FALSE).
4418 Affected file lib/silcutil/silcnet.[ch].
4420 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added silc_pkcs_decode_identifier to decode the public key's
4423 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4424 Added also silc_pkcs_free_identifier. Added also new context
4425 SilcPublicKeyIdentifier.
4427 * Added -S option to the silc client. It is used to dump the
4428 contents of the specified public key file.
4430 * Changed the PKCS api to return the public key length when
4431 setting the public key.
4433 * Fixed a fatal bug in the public and private key file loading.
4434 Affected file lib/silccrypt/silcpkcs.c.
4436 * Execute the packet parsing for client with zero (0) timeout
4437 if the protocol is active. Affected file silcd/server.c.
4439 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Made the key generation options to the silcd program. Added
4442 -C option, equivalent to client's option.
4444 * Added new [ServerKeys] config section to the server. It
4445 configures the server's public and private key.
4447 * Defined generic Public Key Payload into the protocol
4448 specification to send specific type of public keys and
4451 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4452 public key or certificate.
4454 * Implemented the GETKEY command to the server and to the
4455 client library and on user interface.
4457 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Made preliminary `make install' work.
4461 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added SilcServerRekey context into silcd/idlist.h.
4465 * Added the PFS support as defined in the specification to the
4466 SKE protocol. Affected files lib/silcske/*.c.
4468 * Added `ske_group' field to the SilcServerRekey context to hold
4469 the number of the SKE group that is used with PFS in re-key.
4470 Affected file silcd/idlist.h.
4472 * Added PFS re-key support to the server. Affected file is
4475 * Added silc_protocol_cancel to cancel execution of the next
4476 state of the protocol. Affected file is
4477 lib/silccore/silcprotocol.[ch].
4479 * Added the re-key support with and without PFS to the client
4480 library. Re-key is performed once in an hour, by default.
4482 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4483 Added silc_client_rekey_callback and silc_client_rekey_final.
4484 Affected files are lib/silcclient/protocol.[ch] and
4485 lib/silcclient/client.[ch].
4487 * Removed the `hmac_key' and `hmac_key_len' fields from the
4488 SilcClientConnection structure; not needed. Affected file is
4489 lib/silcclient/client.h.
4493 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Do not ask whether user wants to use the negotiated private key
4496 for private messages, just use it. Affected file is
4497 silc/local_command.c.
4499 * Added `send_enc_key' and `enc_key_len' fields to the
4500 SilcIDListData structure since they are needed in the re-key
4501 phase. Affected file is silcd/idlist.[ch].
4503 * Implemented the simple re-key protocol into the server.
4504 Affected files silcd/server.c and silcd/protocol.[ch]. The
4505 re-key will be performed once in an hour, by default.
4507 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4508 Added silc_server_rekey, silc_server_rekey_callback and
4509 silc_server_rekey_final.
4511 * Removed Tunneled flag from the protocol. Updated the code
4512 and the specifications.
4514 * Adde `pfs' field to the SilcIDListData to indicate whether
4515 the PFS is to be performed in the re-key. Affected file is
4518 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4521 int64 of at least the xintXX size. If void * is less that 4
4522 bytes uint32 * will be used. Defined bool as boolean.
4524 * Changed _ALL_ unsigned long and unsigned int to uint32,
4525 unsgined short to uint16 in the source tree.
4527 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4528 not handle clients that has entry->data.registered == FALSE.
4529 They are not in the network anymore. Affected file is
4532 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Implemented the sending of the SERVER_SIGNOFF notify in the
4535 server. Affected file is silcd/server.c.
4537 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4538 Added also silc_notify_payload_encode_args into the
4539 lib/silccore/silcnotify.[ch].
4541 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4542 Affected file silcd/packet_receive.c.
4544 * Implemented the SERVER_SIGNOFF notify handling in the client
4545 library. Affected file lib/silcclient/client_notify.c. Also,
4546 implemnted the printing of the SERVER_SIGNOFF info to the
4547 application. Affected file silc/client_ops.c.
4549 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4550 if the deleting was successful. Affected file silcd/idlist.[ch].
4552 * Added support for public key authentication in the connection
4553 authentication protocol in the client library. Affected file
4554 lib/silcclient/protocol.c.
4556 * Changed the server's silc_idlist_get_clients_by_* interface
4557 to support already allocated array so that new entries may be
4558 added to pre-allocated array. Affected file silcd/idlist.[ch].
4559 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4560 and command replies.
4562 * All command reply functions in the server now calls the
4563 pending command callback even if error occured. This way the
4564 error will be delivered to the client as well. Affected files
4565 silcd/command.c and silcd/command_reply.c.
4567 * Fixed INFO command to return local server's info if no server
4568 was provided. Affected file lib/silcclient/command.c.
4570 * Removed RESTART command for good. Updated the code and the
4573 * Rewrote parts of the task system. It is a bit simpler now.
4574 Removed unsued task priorities. The affected files are
4575 lib/silcutil/silctask.[ch].
4577 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Moved the USERS printing from the library to the application.
4580 Affected files lib/silcclient/command.c and silc/client_ops.c.
4582 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Added channel key re-key support. The re-key is perfomed
4587 only by the router and is done once in an hour. Added `rekey'
4588 field to the SilcChannelEntry in the server. Affected files
4589 silcd/server.c and silcd/idlist.h.
4591 * Added silc_task_unregister_by_context into the file
4592 lib/silcutil/silctask.[ch].
4594 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Added SILC_UMODE_GONE mode to indicate when the client is not
4597 present in the SILC network. Added also support to the local
4598 command AWAY that will set this mode. Added support of showing
4599 "xxx is gone" in WHOIS command. The USERS command shows the
4600 gone status as well.
4602 * Fixed setting server and router operator privileges in the
4603 server's UMODE command. Affected file silcd/command.c.
4605 * Merged the SKE KE1 and KE2 payloads into one payload. The
4606 new KE payload is equivalent to the old KE2 payload.
4608 Cleaned up the SKE Start Payload parsing. It now uses the
4609 simple buffer unformatting to do the parsing. A lot faster
4612 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4613 to the SKE that is used to indicate whether both of the SKE
4614 parties should perform authentication. By default only the
4615 responder performs authentication. By setting this flag also
4616 the initiator must do authentication. By default it is unset
4617 since in normal SKE case, client to server connection, only
4618 the responder should do authentication. When doing SKE between
4619 two clients both should perform authentication. Updated the
4620 code and the protocol specs.
4622 * A little fix to IDENTIFY command in the server. Search the
4623 client first by hash not nickname. Affected file is
4626 * Fixed the silc_client_close_connection to support closing
4627 the client to client connections wihtout deleting too much
4628 data. Affected file lib/silcclient/client.c.
4630 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4631 are received if protocol used to be active but is not anymore
4632 the application would crash due to NULL pointer dereference.
4633 Affected files silcd/server.c and lib/silcclient/client.c.
4635 * Added `hash' field to the SilcClientConnection to include
4636 the hash function negotiated in the SKE protocol.
4638 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4639 to set the channel founder authentication data. A client can
4640 claim the founder rights later by providing the authentication
4641 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4642 This way the channel founder can regain the channel founder
4643 privileges even it is left the channel. This works only on
4644 local server and the client must be connected to the same
4645 server to be able to regain the founder rights. Updated the
4646 protocol specs accordingly.
4648 Added support to the CMODE command in the client to set the
4649 founder auth data. Read the README to see how to set it.
4651 Added support to the CUMODE command to claim the founder
4652 rights. Read the README to see how to do it.
4654 Added support for the founder authentication to the Channel
4655 Entry in the server. Affected file silcd/idlist.h.
4657 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4658 server's CMODE command. Affected file silcd/command.c.
4660 * Added the following new functions into lib/silccore/silcauth.[ch]:
4661 silc_auth_get_method and silc_auth_get_data.
4663 * The server now saves the remote hosts public key to the
4664 SilcIDListData pointer. Affected file silcd/protocol.c.
4666 * The normal server now does not remove the channel entry from
4667 the cache if the founder authentication data is set. It used
4668 to remove it if the founder was the last one on the channel on
4669 the server and left the channel. The auth data is saved and
4670 if the channel is re-joined later the old entry is used with
4671 the old auth data. Affected files silcd/command_reply.c and
4674 * Removed the `pkcs' field from the SilcIDListData structure
4675 in the server; it is not used. Affected file silcd/idlist.h.
4677 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Fixed packet processing on slow links. Partial packets were
4680 never re-processed because the incoming data buffer was cleared
4681 by the application. Application must not directly clear the
4682 sock->inbuf, the packet processing routines handle it. Fixed
4683 this in client library and in server.
4685 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Fixed the WHOIS and IDENTIFY send reply function to really
4688 check whether to send list or just one entry. Affected file
4691 * Cleaned up the LEAVE command's channel key distribution. The
4692 affected file silcd/command.c.
4694 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4695 can enforce the channel mode as well. In that case the ID
4696 includes the ID of the server. The code now enforces the
4697 mode change if the router have different mode than the server.
4699 * The notify client operation with CMODE_CHANGE notify can now
4700 return NULL client_entry pointer if the CMODE was not changed
4701 by client. Application must check for this.
4703 * Added <Server ID> argument to INFO command to support server
4704 info fetching by Server ID.
4706 * Added silc_server_announce_get_channel_users to get assembled
4707 packets of channel users of the specified channel. Affected
4708 file silcd/server.[ch].
4710 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4711 was freed underneath the ID Cache.
4713 * Re-announce clients when the server received CHANNEL_CHANGE
4714 notify from the router. Affected file silcd/packet_send.c.
4716 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4719 crashed since it did not handle the fact that there is no cipher
4720 called "3" and didn't check the error condition. Now fixed.
4722 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4723 flag. It can be used to send message requests.
4725 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Implemented the RESTART command in the client.
4729 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4730 notice type messages. Added notice printing to the user
4733 * The channel keys are not re-generated if the channel's mode
4734 is PRIVKEY, ie private key on the channel exists. Affected
4735 files silcd/server.c and silcd/command.c.
4737 * Fixed a little bug in channel message delivery when channel
4738 private keys are set in the server. Affected file is
4739 silcd/packet_send.c.
4741 * Changed the setting on channel->on_channel = TRUE from the
4742 silc_client_save_channel_key to the JOIN command reply. The
4743 key payload is not received if the private channel key is set.
4744 Affected file lib/silcclient/command_reply.c and the
4745 lib/silcclient/client_channel.c.
4747 * When the CMODE_CHANGE notify is sent and the channel private
4748 key mode is removed the channel key must be re-generated in
4749 other cells as well. Added this support for the router in the
4750 silcd/packet_receive.c.
4752 * Added new local command NOTICE to send notice message on
4753 channel. Affected file silc/local_command.[ch].
4755 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added new local command ME to the client. It is used to send
4758 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4759 some action. Affected file silc/local_command.[ch].
4761 * Changed channel_message and private_message client operations
4762 to deliver the message flags to the application. Added also
4763 the `flags' arguments to the silc_client_send_channel_message
4764 and silc_client_send_private_message functions. Affected file
4767 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Redefined the Private Message Payload to support private message
4770 keys and to support the new private message flags. Updated
4771 the protocol specs. Flags makes it possible to have for example
4772 CTCP style messages.
4774 * Added new type SilcPrivateMessagePayload and defined an API
4775 for it in the lib/silcclient/silcprivate.[ch].
4777 * Tested private message private keys successfully. Tested the
4778 private message key set, unset and list commands with the new
4781 * Redefined the Channel Message Payload to include the channel
4782 message flags (equal with private message flags) to support
4783 for example CTCP style messages.
4785 * Defined some of the message (for channel and private message)
4786 flags. Updated the protocol specs and added the flags to the
4787 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4789 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Added SilcKeyAgreementStatus type to the key agreement routines
4792 to indicate the current status and error if one occured.
4793 The status types are defined in the lib/silcclient/silcapi.h.
4795 * Added new local command KEY that is used to set and unset private
4796 keys for channels, set and unset private keys for private messages
4797 with remote clients and to send key agreement requests and
4798 negotiate the key agreement protocol with remote client. The
4799 key agreement is supported only to negotiate private message keys,
4800 it currently cannot be used to negotiate private keys for channels,
4801 as it is not convenient for that purpose.
4803 * Fixed a minor pending callback setting bug in the function
4804 silc_client_get_client_by_id_resolve, now the function works.
4805 Affected file lib/silcclient/idlist.c.
4807 * Added function silc_net_get_local_port to get local bound
4808 port by socket. Added to lib/silcutil/silcnet.[ch].
4810 * Added `sockets' and `sockets_count' fields to the SilcClient
4811 object. They hold the sockets of the listenning sockets in
4812 the client. Listenning sockets may be for example the key
4813 agreement server. Affected file lib/silcclient/client.[ch].
4814 Added functions the silc_client_add_socket and the
4815 silc_client_del_socket. They are exported to the application
4818 * Added ~./silc/clientkeys to support other client's public keys.
4820 * Renamed verify_server_key client operation to verify_public_key
4821 and added one argument to indicate the type of the connection
4822 (server, client etc.).
4824 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Added silc_server_connection_auth_request to handle the
4827 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4828 silcd/packet_receive.[ch].
4830 * Added silc_server_send_connection_auth_request into the
4831 silcd/packet_send.c to send the connection auth request packet.
4833 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4836 * Fixed the public key authentication in responder side in the
4837 server. The `auth_data' pointer includes the SilcPublicKey
4838 not the path to the public key. Affected file silcd/protocol.c.
4840 * Implemented the public key authentication in the initiator side
4841 in the server. Affected file silcd/protocol.c.
4843 * Removed the [RedirectClient] config section from the server
4844 configuration. Is not needed and I don't want to implement it.
4846 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Cleaned up the CMODE command in the server. It now works
4849 correctly and supports all the modes defined in the protocol.
4850 Affected file is silcd/command.c.
4852 * Added `hmac_name' field to the SilcChannelEntry in the server
4853 to hold the default HMAC of the channel. It can be set when
4854 creating the channel (with JOIN command). Affected files
4857 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4858 type to indicate the change of the current cipher and hmac
4859 on the channel. Client can safely ignore the <cipher> argument
4860 (if it chooses to do so) since the CHANNEL_KEY packet will
4861 force the channel key change anyway. The <hmac> argument is
4862 important since the client is responsible of setting the new
4863 HMAC and the hmac key into use.
4865 * Fixed the CMODE command in the client library as well.
4867 * Tested CMODE command in router environment successfully.
4869 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Show the version of the remote client (or server) when connecting
4872 to the server. It is logged to the log file. Affected file
4873 is silcd/protocol.c.
4875 * Fixed the KILLED notify handling in the client library. The
4876 client must be removed from all channels when receiving the
4879 Also, do not remove the client entry when giving the KILL
4880 command but when the KILLED notify is received.
4882 * Removed silc_idlist_find_client_by_nickname from the server.
4883 Not needed anymore. Affected files silcd/idlist.[ch].
4885 * Implemented the CHANNEL_CHANGE notify type handling to the
4886 server. Affected file silcd/server.c.
4890 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added silc_server_send_notify_invite to send the INVITE
4893 notify between routers.
4895 * Implemented the INVITE command correctly to the server.
4897 * Implemented the INVITE notify type handling in the server.
4899 * Implemented the INVITE command to the client library and on the
4902 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Added function silc_server_get_client_resolve to find the
4905 client entry by ID from all ID lists and then resolve it
4906 (using WHOIS) if it cannot be found. Affected file is
4909 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Implemented the BAN command to the client library.
4913 * The JOIN command in the server now checks the invite list
4916 * Changed the silc_command_reply_payload_encode_va and the
4917 silc_command_payload_encode_va to support that if argument is
4918 NULL it ignores and checks the next argument. Affected file
4919 lib/silccore/silccommand.c.
4921 * Added silc_server_send_notify_ban to send the BAN notify
4922 type between routers.
4924 * Chaned the silc_notify_payload_encode to support that if
4925 argument is NULL it ignores and checks the next argument.
4926 Affected file lib/silccore/silcnotify.c.
4928 * Tested ban lists in router environment successfully.
4930 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Implemented BAN command to the server, in silcd/command.[ch].
4934 * Removed the BAN and INVITE_LIST modes from the CMODE command
4937 * Added function silc_string_match to regex match two strings.
4938 Affected files lib/silcutil/silcutil.[ch].
4940 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Redefined parts of the SilcChannelEntry in the server to support
4943 the new ban and invite lists.
4945 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Redefined the INVITE command. The same command can be used to
4948 invite individuals to the channel but also to manage the invite
4949 list of the channel (to add to and remove from the invite list).
4950 Updated the protocol specs.
4952 * Added new command SILC_COMMAND_BAN that can be used to manage
4953 the ban list of the channel. Updated the protocol specs.
4955 * Removed the channel modes: the SILC_CMODE_BAN and the
4956 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4957 in the CMODE command. The equivalent features are now available
4958 using INVITE and BAN commands. Updated the protocol specs.
4960 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4961 in the network about change in the current ban list. The notify
4962 type is not used by the client.
4964 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4965 support the invite lists.
4967 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Added new function silc_string_regexify that converts string
4970 including wildcard characters into regex string that can
4971 be used by the GNU regex library. Added into the file
4972 lib/silcutil/silcutil.[ch].
4974 Added silc_string_regex_combine to combine to regex strings
4975 into one so that they can be used as one regex string by
4976 the GNU regex library. Added into the file
4977 lib/silcutil/silcutil.[ch].
4979 Added silc_string_regex_match to match two strings. It returns
4980 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4982 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Imported GNU regex to the soruce tree into lib/contrib.
4985 Fixed some compiler warning from the regex.c.
4987 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Fixed MOTD command in the server to work in router environment.
4991 * Fixed the MOTD command in the client library to support
4992 the server argument in the command.
4994 * Added `nickname_len' argument to the silc_idlist_add_client
4995 in the server, as the `nickname' argument may be binary data
4998 * Added silc_idlist_get_channels to return all channels from
5001 * Implemented LIST command to the server. Affected file is
5004 * Implemented the LIST command to the client library and on the
5007 * Added [<user count>] argument to the LIST command reply.
5008 With private channels the user count is not shown.
5010 * Updated TODO and README.
5012 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * The client entry's data.registered must be TRUE even with
5015 global client entry on global client list. The data.registered
5016 is used to check whether the client is anymore in the network,
5017 for example with WHOWAS command so it must be valid.
5019 * Fixed the WHOWAS command in the server. It now actually works
5020 in router environment. Added function into silcd/command_reply.c
5021 silc_server_command_reply_whowas_save.
5023 * Added silc_idlist_purge function to the silcd/idlist.c
5024 to periodically purge the ID Cache.
5026 * Fixed INFO command in the server. It works now in router
5027 environment. Added <server name> argument to the INFO command
5028 reply. Updated the protocol specs.
5030 * Fixed minor bug in silc_idcache_purge to not purge if the
5031 expire value is zero.
5033 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5034 they were buggy because of the WHOWAS information.
5036 * Fixed local command MSG to handle the async resolving of
5037 the remote client properly. It used to fail the first MSG.
5038 Affected file silc/local_command.c.
5040 * Added `data_len' field to SilcIDCache context.
5042 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Update TODO. Todo in commands in the server.
5046 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5049 used by routers as broadcast packet to inform other routers
5050 about the changed user mode.
5052 Implemented the notify handling in the server. Affected file is
5053 silcd/packet_receive.c. Added the function
5054 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5056 * Added new generic Channel Payload and deprecated the New Channel
5057 Payload. The New Channel Payload is now the generic Channel
5060 * Added new argument `mode' to the silc_server_send_new_channel
5061 as it is required in the Channel Payload now.
5063 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5064 and created a new and real SilChannelPayload to represent the
5065 new generic Channel Payload. Implemented the encode/decode
5066 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5068 * Added silc_server_get_client_channel_list to return the list
5069 of channels the client has joined for WHOIS command reply.
5070 Affected file silcd/server.[ch].
5072 * Implemented the channel list sending in the WHOIS command reply
5073 in server and in the client.
5075 Implemented the channel list displaying on the user interface
5076 as well. Affected file silc/client_ops.c.
5078 * Added silc_channel_payload_parse_list to parse list of Channel
5079 Payloads. It returns SilcDList list of SilcChannelPayloads.
5080 Client for example can use this function to parse the list of
5081 channels it receives in the WHOIS command reply. The caller
5082 must free the list by calling silc_channel_payload_list_free.
5083 Affected files lib/silccore/silcchannel.[ch].
5085 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added one new argument <user mode> to the WHOIS command reply
5088 to return the mode of the user in SILC. Updated the protocol
5091 Implemented it to the server and client.
5093 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Fixed the mode printing on the user interface on joining.
5096 Affected file silc/client_ops.c.
5098 * Implemented the UMODE command and user modes in general to the
5099 client library and to the user interface.
5101 * Implemented the UMODE command to the server.
5103 * The server now sends UNKNOWN_COMMAND error status if client sends
5104 unknown command. Affected file silcd/command.c.
5106 * All server commands now handle the command identifier the right
5107 way when sending the command reply to the client. The client can
5108 use to identify the command replies with the identifier.
5110 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Added silc_server_get_client_route to resolve the route to
5113 the client indicated by the client ID. Affected file is
5116 * Added silc_server_relay_packet as general function to relay
5117 packet to arbitrary destination. This deprecates functions
5118 like _send_private_message_key, _relay_notify etc. Affected
5119 file is silcd/packet_send.[ch].
5121 Removed silc_server_send_key_agreement,
5122 silc_server_send_private_message_key and
5123 silc_server_packet_relay_notify functions from the file
5124 silcd/packet_send.[ch].
5128 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5129 server. Affected file silcd/packet_receive.[ch].
5131 * Implemented the KILL command to the client. Implemented the
5132 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5133 Affected files lib/silcclient/command[_reply].c and
5134 lib/silcclient/client_notify.c. Implemented the KILL notify
5135 printing in the user inteface.
5137 * Fixed a lot silc_parse_nick memory leaks from the client
5138 library in the file lib/silcclient/command.c.
5140 * Changed the silc_server_send_notify_on_channels's `sender'
5141 argument from SilcSocketConnection to SilcClientEntry to
5142 check the sender as entry and not as connection object and not
5143 to send to the client provided as argument. The affected file
5144 is silcd/packet_send.[ch].
5146 * The notify packets that are destined directly to the client used
5147 to not to be processed by the server. Now changed that and the
5148 server processes all notify packets. After relaying the packet
5149 to the client the notify packet is processed in the server.
5151 * The silc_server_free_client_data now checks whether there is
5152 pending outgoing traffic for the client and purges the data to
5153 the network before removing the client entry.
5155 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5158 an client is killed from the SILC Network. Updated the protocol
5161 Added new function silc_server_send_notify_killed to the
5162 silcd/packet_send.[ch].
5164 * Added function silc_server_packet_relay_notify to relay notify
5165 packets that are destined directly to a client. In this case
5166 the server does not process the notify packets but merely relays
5167 it to the client. Affected file silcd/packet_send.[ch].
5169 Added also silc_server_packet_process_relay_notify to check
5170 whereto relay the notify. Affected file is
5171 silcd/packet_receive.[ch].
5173 * Implemented the KILL command to the server.
5177 * Added the backup schema desgined last fall to the protocol
5178 specs for everyone to see. The specification is in the
5179 *-spec-xx.txt draft and the packet type definitions for the
5180 backup routers is in *-pp-xx.txt draft. Thusly, added also
5181 new packet type SILC_PACKET_CELL_ROUTERS.
5183 * A big security problem in the implementation discovered. The
5184 signoff of an client did not cause new channel key generation
5185 which it of course should've done. The channel keys must be
5186 always re-generated when client leaves (or signoffs) the channel.
5187 The silc_server_remove_from_channels funtion now handles
5188 the channel key re-generation.
5190 * Added `sender' argument to the silc_server_send_notify_on_channels
5191 to not to send the client provided as argument. Affected file
5192 silcd/packet_send.[ch].
5194 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Implemented OPER and SILCOPER commands into the server and
5199 * Added silc_auth_verify and silc_auth_verify_data to verify
5200 the authentication directly from the authentication payload.
5201 It supports verifying both passphrase and public key based
5202 authentication. Affected file lib/silccore/silcauth.[ch].
5204 * Added `hash' field to the SilcIDListData structure. It is the
5205 hash negotiated in the SKE protocol. Affected file is
5208 * Slight redesigning of the SilcAuthPayload handling routines.
5209 Do not send SilcPKCS but SilcPublicKey as argument.
5211 * Implemented the public key authentication support to the
5212 serverconfig. The public key is loaded from the provided path
5213 and saved as authentication data to void * pointer. Thus,
5214 changed the unsigned char *auth_data to void *auth_data;
5216 * Fixed SHUTDOWN command to send the reply before the server
5217 is shutdown. :) Affected file silcd/command.c.
5219 * Fixed fatal bug in CONNECT command. The hostname was invalid
5220 memory and server crashed. Affected file silcd/command.c.
5222 * Fixed fatal bug in CLOSE command. The server_entry became
5223 invalid but was referenced later in the command. Affected file
5226 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5228 * Fixed fatal bug in failure packet handling. Server ignored
5229 the failure and thus crashed when it came.
5233 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5236 that the command may be executed only once in (about) 2 seconds.
5237 The old SILC_CF_LAG flag is same but allows command bursts up
5238 to five before limiting.
5240 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5241 server code. Various commands now includes the CF_LAG_STRICT
5242 flag to disallow any kind of miss-use of the command.
5244 * Fixed the silc_buffer_unformat to not to allocate any data
5245 if the length of the data is zero. It used to allocate the
5246 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5248 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Changed the format of AdminConnection configuration section
5251 in the server. Added username of the admin to the format.
5252 Affected files silcd/serverconfig.[ch].
5254 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5255 to return admin configuration data by host, username and/or
5258 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Implemented WHOWAS command to the server. Added the functions:
5262 silc_server_command_whowas_parse,
5263 silc_server_command_whowas_send_reply,
5264 silc_server_command_whowas_from_client and
5265 silc_server_command_whowas_from_server
5267 * Added <Client ID> argument to the WHOWAS command reply. Updated
5268 the protocol specs accordingly.
5270 * Implemented WHOWAS command and command_reply to the client
5273 Implemented the WHOWAS printing on the user interface.
5275 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Added new argument to the WHOWAS command reply, the real name.
5278 It is an optional argument. Updated the protocol specs.
5280 * Added SilcIDCacheDestructor callback that is registered when
5281 the SilcIDCache is allocated. The callback is called when
5282 an cache entry in the ID Cache expires, or is purged from the
5283 cache. Added into lib/silccore/idcache.[ch].
5285 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5286 to destruct the client entries when the cache entry expires.
5287 Other ID Cache's in server and in the client library ignores
5290 * If the ID Cache entry's `expire' field is zero then the entry
5291 never expires. Added boolean `expire' argument to the
5292 silc_idcache_add function in the lib/silccore/idcache.[ch].
5293 If it is TRUE the default expiry value is used.
5295 * Added silc_server_free_client_data_timeout that is registered
5296 when client disconnects. By default for 5 minutes we preserve
5297 the client entry for history - for WHOWAS command.
5299 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Added support to the server to enforce that commands are not
5302 executed more than once in 2 seconds. If server receives
5303 commands from client more frequently, timeout is registered
5304 to process the commands. Affected file silcd/command.c.
5305 Added new function silc_server_command_process_timeout.
5307 * Changed NICK_NOTIFY handling in client library to check that
5308 if the client's nickname was changed, so there is no need to
5309 resolve anything from the server.
5311 * Removed error printing from the WHOIS and IDENTIFY commands.
5312 If error occurs then it is ignored silently in the client library.
5313 The application, however, may map the received error to
5314 human readable error string. The application currently maps
5315 the NO_SUCH_NICKNAME error to string.
5317 * Made the command status message public to the application. Moved
5318 them from lib/silcclient/command_reply.c to
5319 lib/silcclient/command_reply.h. The application can map the
5320 received command status to the string with the
5321 silc_client_command_status_message function.
5323 * Added check to the server to check that client's ID is same
5324 as the Source ID in the packet the client sent. They must
5327 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Added dist-bzip hook to the Makefile.am to make bzip2
5330 compressed distributions.
5332 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * Server now enforces the maximum length for the nickname and
5335 the channel as protocol specification dictates. 128 bytes for
5336 nickname and 256 bytes for channel name.
5338 * Moved the WHOIS printing to the application. The client libary
5339 does not print out the WHOIS information anymore, the application
5340 must do it. Renamed silc_client_command_reply_whois_print to
5341 the silc_client_command_reply_whois_save.
5343 The client's idle time is also sent to the application now, and
5344 the idle is shown on screen.
5346 * Added silc_client_command_reply_identify_save to save the
5347 received IDENTIFY entries.
5349 * Do not check for channel private keys in message sending and
5350 reception if the channel does not have the PRIVKEY mode set.
5351 Affected file lib/silclient/client_channel.c.
5353 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5356 just surfaced after chaning the JOIN procedure.
5358 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Added silc_client_get_clients_by_list to get client entries
5361 from Client ID list, that is returned for example by JOIN
5362 and USERS command replies. The application should use this
5363 function for example when JOIN command reply is received to
5364 resolve the clients already on the channel (library does not
5365 do that anymore as USERS command reply is not used in the JOIN
5366 procedure anymore). Affected files lib/silcclient/silcapi.h and
5367 lib/silcclient/idlist.c.
5369 * JOIN command reply and USERS command reply returns now SilcBuffer
5370 pointers instead of unsigned char pointers when returning
5371 the client list and mode list.
5373 * Added <Client ID> argument to the JOIN command reply, mainly
5374 for the server to identify for which client the command was
5375 originally sent. Updated protocol specs accordingly.
5377 * Added SilcDlist private_key pointer to the SilcChannelEntry
5378 in the client to support the channel private keys. Affected
5379 file is lib/silcclient/idlist.h.
5381 * Added SilcChannelPrivateKey argument to the function
5382 silc_client_send_channel_message so that application can choose
5383 to use specific private ke if it wants to. If it is not provided,
5384 the normal channel key is used, unless private keys are set.
5385 In this case the first (key that was added first) is used
5386 as the encryption key.
5388 * Implemented the support for channel private key handling.
5389 Implemented the following functions:
5391 silc_client_add_channel_private_key,
5392 silc_client_del_channel_private_keys,
5393 silc_client_del_channel_private_key,
5394 silc_client_list_channel_private_keys and
5395 silc_client_free_channel_private_keys
5397 Affected file lib/silcclient/client_channel.c.
5399 * Added the support for the private keys in the channel message
5400 sending and encryption and in the message reception and
5401 decryption. Affected funtions are
5402 silc_client_send_channel_message and silc_client_channel_message.
5404 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Added SKE's key verify callback to the client library's
5407 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5409 * Removed the statement that server (or router) must send USERS
5410 command reply when joining to the channel so that the client
5411 knows who are on the channel. Instead, the client list and
5412 client's mode list is now sent in the JOIN command reply to the
5413 client who joined channel. This is better solution.
5415 * Added function silc_server_get_users_on_channel and function
5416 silc_server_save_users_on_channel to the silcd/server.[ch].
5418 * Removed function silc_server_command_send_users from the
5421 * Do not show topic on the client library anymore. The topic is
5422 sent in the command reply notify to the application and the
5423 application must show the topic now.
5425 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Added client searching by nickname hash into the IDENTIFY and
5428 WHOIS commands in the server as they were clearly missing from
5429 them. Affected file is silcd/command.c.
5431 * Fixed a bug in private message receiving in the client library.
5432 The remote ID was freed and it wasn't supposed, now it is
5435 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Minor fix to the channel payload; allocate the data area, as it
5438 needs to be of specific length.
5440 * If the key agreement port is zero then the operating
5441 system will define the bound port. Affected files are
5442 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5444 * Added new function silc_channel_payload_decrypt into the file
5445 lib/silccore/silcchannel.[ch].
5447 * Moved the channel message etc, check from silc_packet_decrypt
5448 to applications. The library calls now a generic
5449 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5450 when the packet is either normal or special. This was done to
5451 allow more wide range of checking that was not allowed when
5452 the code was in library. Now applications can do virtually any
5453 checks to the packet and return to the library the decision how
5454 the packet should be processed. Affected files are
5455 lib/silccore/silcpacket.[ch].
5457 Added silc_server_packet_decrypt_check to the server and
5458 silc_client_packet_decrypt_check to the client library.
5460 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5461 to send with specified source and destination information.
5463 * Channel message delivery between routers was broken after the
5464 channel key distribution was fixed earlier. The channel key
5465 was used be to distributed to other routers as well which is not
5466 allowed by the protocol. Now this is fixed and channel keys
5467 really are cell specific and the channel message delivery between
5468 routers comply with the protocol specification.
5470 * Fixed various commands in server to check also the global list
5471 for the channel entry and not just the local list. The affected
5472 file silcd/command.c.
5474 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Added assert()s to buffer formatting and unformatting routines
5477 to assert (if --enable-debug) when error occurs. Affected
5478 file: lib/silcutil/silcbuffmt.c.
5480 * Changed to auto-reconnect to check whether the remote host is
5481 router and register the re-connect timeout if it is. It used
5482 to check that whether we are normal server, but router must do
5483 auto-reconnect with another router as well. Affected file
5486 * Removed the [<key len>] option from CMODE command as the cipher
5487 name decides the key length, nowadays. See the defined ciphers
5488 from the protocol specification.
5490 * Added [<hmac>] option to the CMODE command to define the HMAC
5491 for the channel. Added SILC_CMODE_HMAC channel mode.
5493 * Added [<hmac>] option for the JOIN command so that user can
5494 select which HMAC is used to compute the MACs of the channel
5497 * Added Hmac field to the Channel Message Payload. The integrity
5498 of plaintext channel messages are now protected by computing
5499 MAC of the message and attaching the MAC to the payload. The
5500 MAC is encrypted. Now, it is clear that this causes some
5501 overhead to the size of the packet but rationale for this is that
5502 now the receiver can verify whether the channel message decrypted
5503 correctly and also when private keys are set for the channel the
5504 receiver can decrypt the packet with several keys and check from
5505 the MAC which key decrypted the message correctly.
5507 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5508 lib/silccrypt/silccipher.[ch].
5510 * Added silc_hash_len to return the digest length into the
5511 lib/silcrypt/silchash.[ch].
5513 * Rewrote parts of Silc Channel Payload interface in the
5514 lib/silccore/silcchannel.[ch]. The encode function now also
5515 encrypts the packet and parse function decrypts it.
5517 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Fixed a minor formatting bug in the SKE's key material processing.
5520 It actually might have processed the keys wrong way resulting
5523 * Redefined the mandatory HMAC algorithms and added new algorithms.
5524 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5525 and hmac-md5 truncated to 96 bits. The mandatory is now
5526 hmac-sha1-96. Rest are optional (including the one that used
5527 to be mandatory). Rationale for this is that the truncated HMAC
5528 length is sufficient from security point of view and can actually
5529 make the attack against the HMAC harder. Also, the truncated
5530 HMAC causes less overhead to the packets. See the RFC2104 for
5533 * Added new [hmac] configuration section. The SKE used to use
5534 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5535 is of course wrong. The official names that must be proposed in
5536 the SKE are the ones defined in the protocol specification
5537 (hmac-sha1-96 for example). The user can configure any hmac
5538 using any hash function configured in the [hash] section. At
5539 least, the mandatory must be configured.
5541 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5543 * Added HMAC list to the SKE proposal list. It has now both
5544 hash algorithm list and HMAC list. This makes the protocol
5545 incompatible with previous versions. The SKE now seems to work
5546 the way it is supposed to work, for the first time actually.
5548 * Defined plain Hash algorithms to the protocol specification.
5551 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Implemented support for key agreement packets into the server.
5554 Added functions silc_server_key_agreement and
5555 silc_server_send_key_agreement. Other than these functions,
5556 server has nothing to do with this packet.
5558 * Added support for private message key packets into the server.
5559 Added functions silc_server_private_message_key and
5560 silc_server_send_private_message_key.
5564 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5565 called in the protocol's final callback instead in the END
5566 protocol state. This makes a little more sense and in the same
5567 time in client we can use the same protocol routines for normal
5568 key exchange and to key agreement packet handling as well.
5570 * Added to both client's and server's KE protocol context the
5571 SilcSKEKeyMaterial pointer to save the key material. We will
5572 bring the key material to the protocol's final callback by doing
5573 this. The final callback must free the key material.
5575 * Added SKE's packet_send callback into client's KE protocol
5576 context so that the caller can choose what packet sending function
5577 is used. This way we can use different packet sending when
5578 doing normal SKE when doing key agreement packet handling (in
5579 the key agreement packet handling we do not want to encrypt
5582 * Implemented the responder side of the key agreement routines
5583 in the client. The client can now bind to specified port and
5584 accept incoming key negotiation. The key material is passed
5585 to the application after the protocol is over.
5587 * Implemented the processing of incoming Key Agreement packet
5588 in the client. Added function silc_client_key_agreement to
5591 * Implemented the intiator side of the key agreement routines
5592 in the client. The client can now initiate key agreement with
5593 another remote client. The key material is passed to the
5594 application after the protocol is over.
5596 * Created client_keyagr.c to include all the key agreement
5599 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5600 SILC_TASK_CALLBACK except that it is not static.
5602 * Created client_notify.c and moved the Notify packet handling
5603 from the client.[ch] into that file.
5605 * Created client_prvmsg.c and moved all private message and
5606 private message key routines from the client.[ch] into that file.
5608 * Create client_channel.c and moved all channel message and
5609 channel private key routines from the client.[ch] into that file.
5611 * Changed silc_client_get_client_by_id_resolve to resolve with
5612 WHOIS command instead of IDENTIFY command, in the file
5613 lib/silclient/idlist.c.
5615 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Implemented the SKE's responder side to the Client library.
5619 * When FAILURE is received to the protocol do not trust it
5620 blindly. Register a timeout to wait whether the remote closes
5621 the connection as it should do it, only after that process the
5622 actual failure. This was changed to both client and server.
5624 * Added client_internal.h to include some of the structures
5625 there instead of client.h in lib/silcclient/.
5627 * Added function silc_task_unregister_by_callback to unregister
5628 timeouts by the callback function.
5630 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Some "Incomplete WHOIS info" errors has been appearing on the
5633 log files. Took away the entry->userinfo check from WHOIS
5634 reply sending. The entry->userinfo is now " " if client did not
5635 provide one. I thought this was fixed earlier but something
5636 is wrong still. Let's see if the error still appears.
5638 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Fixed a minor bug in the login when the channel key is
5641 re-generated in the server. It used to generate the key in
5642 wrong order and thus caused problems in the channel traffic.
5644 * Fixed a minor bug in channel key distsribution after
5645 KICK command. The key was not sent to the router even though
5648 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Added silc_ske_process_key_material_data as generic routine
5651 to process any key material as the SILC protocol dictates. The
5652 function is used by the actual SKE library but can be used by
5653 applications as well. This relates to the private message keys
5654 and the channel private keys since they must be processed the
5655 same way the normal SILC session keys. The protocol dictates
5656 this. Affected files: lib/silcske/silcske.[ch].
5658 Added also silc_ske_free_key_material to free the
5659 SilcSKEKeyMaterial structure.
5661 * Defined silc_cipher_set_key function to set the key for
5662 cipher without using the object's method function. The affected
5663 files: lib/silccrypt/silccipher.[ch].
5665 * Implemented silc silc_client_add_private_message_key,
5666 silc_client_add_private_message_key_ske,
5667 silc_client_del_private_message_key,
5668 silc_client_list_private_message_keys and
5669 silc_client_free_private_message_keys functions in the
5672 Added functions silc_client_send_private_message_key to send
5673 the Private Message Key payload and silc_client_private_message_key
5674 to handle incoming Private Message Key payload.
5676 * Added Cipher field to the Private Message Key payload to set
5677 the cipher to be used. If ignored, the default cipher defined
5678 in the SILC protocol (aes-256-cbc) is used.
5680 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Removed lib/silcclient/ops.h file.
5684 Redefined parts of the SILC Client Library API. Created new
5685 file silcapi.h that deprecates the ops.h file and defines the
5686 published Client Library API. Defined also private message key
5687 API and channel private key API into the file.
5689 This is the file that the application must include from the
5690 SILC Client Library. Other files need not be included by
5691 the application anymore.
5693 * Added new key_agreement client operation callback and also
5694 defined the Key Agreement library API for the application.
5696 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5699 is used by clients to request key negotiation between another
5700 client in the SILC network. If the negotiation is started it
5701 is performed using the SKE protocol. The result of the
5702 negotiation, the secret key material, can be used for example
5703 as private message key.
5705 Implemented the Key Agreement payload into the files
5706 lib/silccore/silauth.[ch].
5708 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Redefined ciphers for the SILC protocol. Added some new ciphers
5711 and defined the key lengths for the algorithms. Changed the
5712 code accordingly. The default key length is now 256 bits.
5714 * Fixed SKE key distribution function silc_ske_process_key_material
5715 when the key length is more than 128 bits. The default key
5716 length in SILC is now 256 bits.
5718 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5719 to indicate unsupported algorithm.
5721 * Renamed rijndael.c to aes.c and all functions as well.
5723 * Fixed a long standing channel key setting bug in client library.
5724 Weird that it has never surfaced before.
5726 * Fixed bug in channel deletion. If the entire channel is removed
5727 then it must also delete the references of the channel entry
5728 from the client's channel list as the client's channel entry and
5729 the channel's client entry share same memory.
5731 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Implemented CONNECT and SHUTDOWN commands in the client.
5735 * Implemented CLOSE command to the client.
5737 * Added the function silc_idlist_find_server_by_name into the
5738 files silcd/idlist.[ch].
5740 Added the function silc_idlist_find_server_by_conn into the
5741 files silcd/idlist.[ch].
5743 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * DIE command was renamed to SHUTDOWN. Updated the both code
5748 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5749 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5751 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5754 * Added function silc_server_create_connection function to create
5755 connection to remote router. My server implementation actually
5756 does not allow router to connect to normal server (it expects
5757 that normal server always initiates the connection to the router)
5758 so the CONNECT command is only good for connecting to another
5761 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5764 or some other client was kicked from the channel.
5766 Implemented the handling of the notify type to both client
5769 Implemented silc_server_send_notify_kicked to send the KICKED
5770 notify. It is used to send it to the server's primary router.
5772 * Implemented the KICK command into server and client.
5774 * Added `query' argument to the silc_idlist_get_client function
5775 to indicate whether to query the client from server or not if
5778 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5779 to indicate that the client is not channel founder.
5783 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Removed the rng context from SilcPacketContext structure and
5786 changed that the packet routine uses the Global RNG API.
5788 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added support for quit message that client can "leave" on the
5791 channel when it quits the SILC. It is ditributed inside the
5792 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5794 Added silc_server_free_client_data that will take the
5795 signoff message as argument.
5797 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5799 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Updated parts of the protocol specification to keep it up
5804 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5807 payloads in one packet.
5809 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5810 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5811 use now the new List flag.
5813 * Also deprecated the following packet types: REPLACE_ID,
5814 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5816 * Added list support for Notify packet in server.
5818 * Added silc_server_send_notify_channel_change to send the
5819 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5820 the silc_server_send_replace_id.
5822 * Added silc_server_send_notify_nick_change to send the
5823 NICK_CHANGE notify type. Deprecates the function
5824 silc_server_send_replace_id.
5826 * Added silc_server_send_notify_join to send the JOIN notify type.
5827 Deprecates the function silc_server_send_new_channel_user.
5829 * Added silc_server_send_notify_leave to send LEAVE notify type.
5830 Deprecates the function silc_server_send_remove_channel_user.
5832 * Added silc_server_send_notify_cmode and
5833 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5834 types. Deprecates the silc_server_send_set_mode function.
5836 * Added SERVER_SIGNOFF notify type to indicate that server has
5837 quit. This means that all clients on the channel from that
5838 server will drop. This can be also used when netsplit happens.
5840 Deprecated REMOVE_ID packet type since it is not needed anymore
5843 Added silc_server_send_notify_server_signoff to send the
5844 SERVER_SIGNOFF notify type. Deprecates the function
5845 silc_server_send_remove_id.
5847 Added also silc_server_send_notify_signoff to send the
5848 SIGNOFF notify type.
5850 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5851 SILC protocol from this day on. Changed the protocol
5852 specification as well.
5854 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5855 notify type. It is used between routers to notify about
5856 topic changes on a channel.
5858 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5861 * Partly updated the protocol specification to comply with the
5862 changes now made. It is still though a bit outdated.
5864 * The JOIN notify type now takes one extra argument <Channel ID>.
5865 The packet used to be destined to the channel but now the
5866 JOIN type may be sent as list thus it is impossible to
5867 destine it to any specific channel. By adding this argument
5868 it is again possible.
5870 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Added CREDITS file. The CHANGES and CREDITS file will appear
5873 in the distribution as well.
5875 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5878 types in the server's silcd/packet_receive.c.
5880 * Implemented CMODE and CUMODE to work in router environment.
5882 * Fixed minor encoding and decoding buglet from the
5883 lib/silccore/silcmode.c.
5885 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5888 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5890 * Changed all SilcConfigServer* and silc_config_server* to
5891 SilcServerConfig* and silc_server_config*, respectively.
5894 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Associated the ID (client or server ID) to the Authentication
5897 Payload to avoid any possibility of forging. Updated the
5898 protocol specification and the code accordingly.
5900 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * The RSA key length is now save to the RsaKey context in the
5903 key generation process in lib/silccrypt/rsa.c. The key length
5904 is now used to figure out the maximum size of the block allowed
5905 to be encrypted/signed.
5907 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5908 is equivalent to the silc_mp_mp2bin but does not allocate any
5911 * Changed silc_mp_mp2bin API to take length argument. If it is
5912 non-zero then the buffer is allocated that large. If zero, then
5913 the size is approximated using silc_mp_sizeinbase, which however
5916 * Created Global RNG API which is global RNG that application can
5917 initialize. After initializing, any routine anywhere in the
5918 code (including library) can use RNG without allocating a new
5919 RNG object. This was done to allow this sort of use of the
5920 RNG in code that has no chance to allocate RNG object. All
5921 applications currently allocate this and many routines in the
5922 library use this. Affected file lib/silccrypt/silcrng.[ch].
5924 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5925 it to use the Global RNG API.
5927 * Defined Authentication Payload into protocol specification that
5928 is used during SILC session to authenticate entities. It is
5929 used for example by client to authenticate itself to the server
5930 to obtain server operator privileges.
5932 Implemented this payload into the lib/silccore/silcauth.[ch].
5933 Implemented also routines for public key based authentication
5934 as the new protocol specification dictates.
5936 Moved definitions of different authentication methods from
5937 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5939 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5940 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5941 silc_pkcs_verify_with_hash functions into the file
5942 lib/silccrypt/silcpkcs.[ch].
5944 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * The client entry's userinfo pointer must be always valid.
5947 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5948 will fail since it requires the userinfo. Now, the userinfo
5949 is allocated as "" if actual userinfo does not exist. Actually,
5950 it must exist and it is totally Ok to drop client connections
5951 that does not announce the userinfo. However, we will make
5952 this workaround for now.
5954 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5955 to return the remote port by socket.
5957 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5960 SILC_SERVER_PENDING_EXEC and added an new macro
5961 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5962 data or when error occurs while processing the pending command.
5964 Added new argument `destructor' into silc_server_command_pending
5965 and to the SilcServerCommandPending object. This destructor is
5966 now called after calling the pending callback or if error occurs
5967 immediately. If error occurs the actual pending callback won't
5968 be called at all - only the destructor. The destructor may be
5969 NULL if destructor is not needed.
5971 All this applies for client library code as well. Similar
5972 changes were made there as well for the pending commands.
5974 In the client, the application must now allocate the
5975 SilcClientCommandContext with the silc_client_command_alloc
5978 * Added reference counter to the SilcServerCommandContext. Added
5979 function silc_server_command_alloc and silc_server_command_dup
5982 Same type of functions added to the client library for the same
5985 * Removed the cmd_ident from IDListData away since it is now
5986 global for all connections. It is the command identifier used
5987 in command sending and with pending commands. The affected file
5990 * Added reference counter to the SilcSocketConnection objecet to
5991 indicate the usage count of the object. The object won't be
5992 freed untill the reference counter hits zero. Currently only
5993 server uses this, and client ignores it. The client must be
5994 set to use this too later. The affected files are
5995 lib/silccore/silcsockconn.[ch]. Added also the function
5996 silc_socket_dup to increase the reference counter.
5998 This was mainly added because it is possible that the socket
5999 is removed underneath of pending command or other async
6000 operation. Now it won't be free'd and proper DISCONNECTING
6001 flags, etc. can be set to avoid sending data to connection that
6002 is not valid anymore.
6004 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6005 the connection. After that it sets SILC_SET_DISCONNECTED.
6006 It is, however, possible that the socket data is not still freed.
6007 The silc_server_packet_process now checks that data is not
6008 read or written to connection that is DISCONNECTED. The socket
6009 get's freed when the reference counter hits zero.
6011 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Changed the client operation API: channel_message operation's
6014 `sender' is now the client entry of the sender, not the nickname
6015 and the `channel' is the channel entry, not the channel name.
6017 In the private_message operation the `sender' is now also the
6018 client entry of the sender not the nickname.
6020 Affected file is lib/silcclient/ops.h and all applications
6021 using the client operations.
6023 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Moved the calling of ops->connect() from connect_to_server_final
6026 into receive_new_id functin since that is the point when the
6027 client is actually allowed to send traffic to network. The
6028 affected file is lib/silcclient/client.c.
6030 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6033 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6034 (if needs broadcasting) instead of broadcasting the packets one
6035 by one which would make a burst in the network traffic.
6037 * Added `broadcast' argument to the functions in silcd/server.[ch]
6038 silc_server_create_new_channel[_with_id] to indicate whether
6039 to send New Channel packet to primary router.
6041 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added new function into the silcd/server.[ch] files:
6044 silc_server_create_new_channel_with_id to create new channel with
6045 already existing Channel ID.
6047 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6048 lib/silccore/silcpacket.h. This packet is used t send list of
6049 Set Mode payloads inside one packet. Server uses this to set
6050 the modes for the channels and clients on those channels, that it
6051 announced to the router when it connected to it. The protocol
6052 specification has been updated accordingly.
6054 * The silc_server_new_channel did not handle the packet coming
6055 from normal server as it normally does not send that. However,
6056 when it announces its channels it does send it. Implemented
6057 the support for that.
6059 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6060 into the file lib/silccore/id.h.
6062 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Fixed memory leaks in the functions silc_idlist_del_client,
6065 silc_idlist_del_channel and silc_idlist_del_server in the file
6066 silcd/idlist.c. All of those leaked like a sieve.
6068 * Fixed some small memory leaks in the client's function
6069 silc_client_notify_by_server.
6071 * Added functions into silcd/server.c: silc_server_announce_clients,
6072 silc_server_announce_channels and silc_server_announce_server.
6073 These functions are used by normal and router server to announce
6074 to its primary router about clients, channels and servers (when
6075 router) that we own. This is done after we've connected to the
6078 These functions effectively implements the following packet types:
6079 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6080 and SILC_PACKET_NEW_ID_LIST.
6082 * Added new functions into the silcd/packet_receive.[ch]:
6083 silc_server_new_id_list, silc_server_new_channel_list and
6084 silc_server_new_channel_user_list to handle the incoming
6085 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6087 * Added support of changing Channel ID in the function
6088 silc_server_replace_id. If the server that announces a channel
6089 to the router already exists in the router (with same name but
6090 with different Channel ID), router is responsible to send
6091 Replace ID packet to the server and force the server to change
6092 the Channel ID to the one router has.
6094 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6095 client that the Channel ID has been changed by the router. The
6096 normal server sends this to the client. Client must start using
6097 the new Channel ID as the channel's ID.
6099 Implemented handling of this new type into lib/silcclient/client.c
6100 into the function silc_client_notify_by_server.
6102 * Added new function silc_idlist_replace_channel_id into the files
6103 silcd/idlist.[ch] to replace the Channel ID.
6105 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Call silc_server_command_identify_check always when processing
6108 the IDENTIFY command in silcd/command.c
6110 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6113 send keepalive packets. The packet can be sent by clients,
6114 servers and routers.
6116 Added function silc_socket_set_heartbeat into the file
6117 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6118 If not set, the heartbeat is not performed. The actual
6119 heartbeat is implemented in the low level socket connection
6120 library. However, application is responsible of actually
6123 Added silc_server_send_heartbeat to send the actual heartbeat
6124 packet into silcd/packet_send.[ch]. Server now performs
6125 keepalive with all connections.
6127 * Added silc_task_get_first function into lib/silcutil/silctask.c
6128 to return the timeout task with shortest timeout. There was a bug
6129 in task unregistration that caused problems. TODO has been
6130 updated to include that task system must be rewritten.
6132 * The client library will now resolve the client information when
6133 receiving JOIN notify from server for client that we know but
6134 have incomplete information.
6136 * Rewrote parts of silc_server_remove_from_channels and
6137 silc_server_remove_from_one_channel as they did not remove the
6138 channel in some circumstances even though they should've.
6140 * Encryption problem encountered in server:
6142 The LEAVE command used to send the Channel Key packet to the
6143 router immediately after generating it. However, the code
6144 had earlier sent Remove Channel user packet but not immediately,
6145 ie. it was put to queue. The order of packets in the router
6146 was that Channel Key packet was first and Remove Channel User
6147 packet was second, even though they were encrypted in the
6148 reverse order. For this reason, MAC check failed. Now, this
6149 is fixed by not sending the Channel Key packet immediately but
6150 putting it to queue. However, this is more fundamental problem:
6151 packets that are in queue should actually not be encrypted
6152 because packets that are sent immediately gets encrypted
6153 actually with wrong IV (and thus MAC check fails). So, packets
6154 that are in queue should be encrypted when they are sent to
6155 the wire and not when they put to the queue.
6157 However, the problem is that the current system has not been
6158 designed to work that way. Instead, the packet is encrypted
6159 as soon as possible and left to the queue. The queue is then
6160 just purged into wire. There won't be any fixes for this
6161 any time soon. So, the current semantic for packet sending
6164 o If you send packet to remote host and do not force the send
6165 (the packet will be in queue) then all subsequent packets to the
6166 same remote host must also be put to the queue. Only after the
6167 queue has been purged is it safe again to force the packet
6170 o If you send all packets immediately then it safe to send
6171 any of subsequent packets through the queue, however, after
6172 the first packet is put to queue then any subsequent packets
6173 must also be put to the queue.
6175 Follow these rules and everything works fine.
6177 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added new function silc_server_remove_clients_by_server to
6180 remove all client entries from ID list when the server connection
6181 is lost. In this case it is also important to invalidate all
6182 client entires as they hold the invalid server entry. This
6183 fixes fatal bug when server has lost connection and will reconnect
6186 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6188 * Made some sanity checks to silc_server_daemonise like to check
6189 whether the requested user and group actually exists.
6191 * Added sanity check to SKE's silc_ske_responder_finish to check
6192 that the public and private key actually is valid.
6194 * Invalidate the client's nickname when receiving Replace ID
6195 packet and the Client ID is being replaced. This means that the
6196 server will query the nickname if someone needs it (client)
6199 * Sort the ID Cache in client library when the ID Cache data
6200 has changed (needs sorting).
6202 * Do not allow for SILC client to create several connections to
6203 several servers. The client does not support windows right now
6204 and generating multiple connections causes weird behaviour.
6206 Irssi-silc client does support windows and can handle several
6207 connections without problems, see: www.irssi.org and SILC plugin.
6209 * Fixed some places where client was added to the IDList. The
6210 rule of thumb is following (in order to get everything right):
6211 If the client is directly connected local client then the
6212 `connection' argument must be set and `router' argument must be
6213 NULL to silc_idlist_add_client function. If the client is not
6214 directly connected client then the `router' argument must
6215 bet set and the `connection' argument must be NULL to the
6216 silc_idlist_add_client function.
6218 * The funtion silc_server_packet_send_local_channel actually did
6219 not check whether the client was locally connected or not. It
6220 does that now. Fixed a bug related to LEAVE command.
6222 * Fixed Remove Channel User payload parsing bug in server's
6223 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6225 * The server's silc_server_save_channel_key now checks also the
6226 global ID list for the channel as it might not be in the local
6227 list. Fixed a bug related to LEAVE command.
6229 * Is this the end of the [<unknown>] buglet that has been lurking
6230 around for a long time? A little for loop fix in server's
6231 silc_server_command_whois_parse that is used by both IDENTIFY
6232 and WHOIS command. At least, this was a clear bug and a cause
6233 of one type of [<unknown>] buglet.
6235 * WHOIS and IDENTIFY commands call the function
6236 silc_server_command_[whois/identify]_check function even if
6237 we are not router server.
6239 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Added --with-gmp configuration option. If set the GMP
6242 is always compiled in the SILC source tree. If not set then
6243 it is checked whether the system has the GMP3 installed. If
6244 it has then the GMP won't be compiled (the system's headers
6245 and library is used), if it doesn't have it then the GMP is
6246 compiled in the SILC source tree.
6248 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Changed RSA private exponent generation to what PKCS #1
6251 suggests. We try to find the smallest possible d by doing
6252 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6253 not security fix but optimization.
6255 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Added new config entry [Identity] to fork the server and run
6258 it as specific user and group. A patch from Bostik.
6260 * Imported Dotconf configuration library into lib/dotconf.
6261 This will be used to create the SILC configuration files later.
6262 It will appear in the distsribution after this commit.
6264 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * A big code auditing weekend happening. Auditing code for
6267 obvious mistakes, bugs and errors. Also, removing any code
6270 Removed files for being obsolete:
6272 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6273 inline in the file lib/silcutil/silcbuffer.h)
6275 o lib/silcutil/silcbufutil.c (the header has inline versions)
6277 Changed code to fix possible error conditions:
6279 o The buffer formatting routines now check that the destination
6280 buffer really has enough space to add the data. This applies for
6281 both buffer formatting and unformatting
6282 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6283 unformatting was changed to accomodate following rules:
6284 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6285 sent to the function while XXX_*STRING will not allocate or copy
6286 the data into the buffer. Instead it sets the pointer from the
6287 buffer into the pointer sent as argument (XXX_*STRING used to
6288 require that the pointer must be allocated already). This change
6289 makes this whole thing a bit more consistent and more optimized
6290 (note that the data returned in the unformatting with XXX_*STRING
6291 must not be freed now). The routines return now -1 on error.
6293 o Tried to find all code that use buffer_format and buffer_unformat
6294 and added return value checking to prevent formatting and
6295 especially unformatting errors and possible subsequent fatal
6298 o Changed ske->x and ske->KEY to mallocated pointers in
6299 lib/silcske/silcske.h. Fixed possible data and memory leak.
6301 o Added return value checking to all *_parse* functions. Fixed
6302 many memory leaks as well.
6304 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6305 so that buffer overflows would not happen. All code now also
6306 checks the return value as it can fail.
6308 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6310 * Added reconnection support to server if the normal server looses
6311 its connection to the router (for example if router is rebooted).
6312 The server performs normal reconnection strategy implemented
6313 to the server. Affected file silcd/server.c.
6315 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Added new packet type SILC_PACKET_SET_MODE that is used to
6318 distribute the information about changed modes (for clients,
6319 channels and clients channel modes) to all routers in the
6320 network. Updated the protocol specification accordingly.
6322 Added functions into silcd/packet_send.c and
6323 silcd/packet_receive.c: silc_server_send_set_mode,
6324 silc_server_set_mode.
6326 Added new files silcmode.[ch] into lib/silccore that implements
6327 the encoding and decoding of Set Mode Payload. Added new type
6328 SilcSetModePayload. Moved the definitions of different modes
6329 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6331 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Oops, a little mistake in server's connection authentication
6334 protocol. The protocol is not ended with FAILURE but with
6335 SUCCESS if the authentication is Ok. :) Affected file is
6338 * Implemented NICK_CHANGE notify handling in server in the file
6339 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6340 the local clients on the channel. After the changing nickname
6341 in router environment snhould work and the [<unknown>] nickname
6342 should appear no more.
6344 The silc_server_replace_id function that receives the Replace ID
6345 payload now sends the NICK_CHANGE notify type also in the file
6346 silcd/packet_receive.c
6348 * Changed WHOIS and IDENTIFY command to support the maximum amount
6349 of arguments defined in protocol specs (3328 arguments). This
6350 fixed a bug that caused problems when there were more than three
6353 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6355 * Added extra parameter, command identifier, to the
6356 silc_client_send_command so that explicit command identifier
6359 Changed that ID list routines uses specific command identifier
6360 when sending WHOIS/IDENTIFY requests to the server so that they
6361 can be identified when the reply comes back.
6363 Affected files lib/silcclient/command.[ch],
6364 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6366 * Added `sender' argument to silc_server_packet_send_to_channel
6367 to indicaet the sender who originally sent the packet to us
6368 that we are now re-sending. Ignored if NULL. Affected file
6369 silcd/packet_send.[ch].
6371 * Added some server statistics support in silcd/server_internal.h
6372 SilcServerStatistics structure and around the server code. Also
6373 send some nice statistics information when client is connecting
6376 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6378 * Fixed channel ID decoding in server's JOIN command reply in
6379 silcd/command_reply.c
6381 * Fixed braodcasting of replace ID payload to not to send it if
6382 we are standalone server in silcd/packet_receive.c.
6384 * Fixed all channel message sending routines to not to send
6385 packets to clients that has router set, since they are routed
6386 separately in the same function earlier. Affects file
6387 silcd/packet_send.c and all channel packet sending functions.
6389 * In USERS reply, res_argv[i] are not allocated, the table
6390 is allocated. Thus changed that free the table, not its
6393 * In server's whois_check and identify_check if the client is
6394 locally connected do not send any WHOIS commands - they are not
6397 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Fixed some minor bugs in client when sending WHOIS command. The
6400 arguments was in wrong order.
6402 * Removed statis function add_to_channel from server in
6403 silcd/command.c that was previously used with the joining but
6406 * Tested USERS command in router environment successfully with two
6407 routers, two servers and two clients.
6409 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Reorganized the USERS command and command reply in client library
6412 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6413 When the command is given by user we register a pending command
6414 callback that will reprocess the command after the reply has been
6415 received from the server. When reprocessing the packet we then
6416 display the information. Thus, the USERS information is displayed
6417 now in the command callback instead of in the command reply
6418 callback. The processing of the command is same as previously
6419 when server has sent the command reply in the JOINing process.
6421 * Added to USERS command in silcd/command_reply.c to join the client,
6422 we didn't use to know about, to the channel after we've created
6423 a client entry for it. Also, for clienet we did know already still
6424 check whether it is on the channel or not and add it if not.
6426 * Removed silc_server_command_join_notify as the function and its
6429 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Changed the client's pending command handling to the same as the
6432 server's pending command handling. It is also now possible to
6433 execute command reply functions from other command reply
6434 function as the function callbacks for commands and command
6435 replies are one and same. The pending commands are not static
6436 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6437 in client connection context. Thus, pending commands are server
6438 connection specific as it is convenient.
6440 Changed the function silc_client_command_pending and
6441 silc_client_command_pending_del and added new function
6442 silc_client_command_pending_check. Removed the
6443 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6446 * Added cmd_ident, current command identifier, to the client
6447 connection context in lib/silcclient/client.h to keep track on
6448 command identifiers used in command sending. Client's command reply
6449 function handling now supports the mandatory command identifiers.
6451 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6452 funtions in client to fully support pending command callbacks.
6454 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6455 as one of the arguments to the application in the command reply
6458 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6459 before first releasing SILC but came back. Now it is removed again
6460 and should come back nomore. The FORWARDED flag was used only
6461 by the JOINing procedure by forwarding the command packet to router.
6462 Now, the JOINing procedure has been changed to more generic (due
6463 to various router environment issues) and FORWARDED is not needed
6464 anymore for anything. The protocol specification is yet to be
6467 Now, removed silc_server_packet_forward from server and the flag
6468 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6470 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Renamed NAMES command to USERS command. The NAMES was named that
6473 due to historical reasons. Now it is renamed. Also, rewrote
6474 parts of the USERS command. The nickname list is not sent anymore
6475 by the server. Only Client ID and mode lists are sent in the USERS
6476 command. Changed this also to the protocol specification.
6478 The client now resolves the names and stuff after it receives
6479 the USERS list from the server when joining to the channel.
6481 * WHOIS and IDENTIFY commands has been changed to support multiple
6482 Client ID's per command. One can now search for multiple users
6483 in the network by sending only one WHOIS or IDENTIFY command.
6484 Changed the code and the protocol specifications.
6486 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6487 uses silc_server_command_whois_parse to parse the request. */
6489 * If normal server, do not parse the WHOIS and IDENTIFY requests
6490 before sending it to the router. Saves some time.
6492 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * Fixed JOIN command on client library. Wrong number of arguments
6495 used to crash the client.
6497 * Added silc_server_channel_has_global function to check whether
6498 channel has global users or not.
6500 * Added silc_server_channel_has_local function to check whether channel
6501 has locally connected clients on the channel.
6503 * The silc_server_remove_from_one_channel now checks whether the
6504 channel has global users or not after given client was removed from
6505 the channel. It also checks whether the channel has local clients
6506 on the channel anymore. If it does not have then the channel entry
6507 is removed as it is not needed anymore.
6509 * The silc_server_notify now checks on JOIN notify whether the joining
6510 client is one of locally connected or global. If it is global then
6511 the channel has now global users on the channel and that is marked
6512 to the channel entry. Also, it now saves the global client to
6513 global list who is joining and JOINs it to the channel. This is
6514 for normal server, that is.
6516 Changed silc_server_send_notify_on_channel,
6517 silc_server_packet_relay_to_channel and
6518 silc_server_packet_send_to_channel check if we are normal server
6519 and client has router set (ie. global client) do not send the
6520 message to that client, as it is already routed to our router.
6522 * Implemented LEAVE notify type handling in silc_server_notify
6525 * Tested LEAVE command in router environment successfully. Tested
6526 with two routers, two servers and two clients.
6530 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6532 * Implemented SIGNOFF notify type handling in silc_server_notify
6535 * silc_server_remove_id now removes the client entry from all channels
6536 it has joined and thusly sends SIGNOFF notify type.
6538 * Rewrote the NAMES list generation in server by removing two excess
6539 loops. The lists are created now inside one loop.
6541 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * silc_server_remove_channel_user checks now also global list
6544 for channel and client.
6546 * silc_server_new_channel_user checks now both local and global
6547 list for channel and client. Fixed a bug in client id decoding.
6548 Used to decode wrong buffer.
6550 * silc_server_channel_message checks now both local and global
6551 list for channel entry.
6553 * Tested channel joining (hence JOIN) in router environment
6554 successfully. Tested with two routers, two servers and two
6557 * Tested channel message sending in router environment successfully.
6559 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Added silc_server_save_channel_key into server.[ch] to save the
6562 received channel key in Channel Key payload processing. It is
6563 also used in JOIN command reply handling.
6565 Equivalent function silc_client_save_channel_key added into
6566 client.[ch] into client library.
6568 * Changed JOIN command reply to send information whether the channel
6569 was created or not (is existing already) and the channel key
6570 payload. Changed protocol specs accordingly.
6572 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6573 the request was sent by ID and not by nickname. Crashed on
6576 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6579 now correctly save the received data.
6581 * silc_server_free_sock_user_data now notifies routers in the
6582 network about entities leaving the network.
6584 At the same time implemented functions silc_server_remove_id
6585 and silc_server_send_remove_id to receive and send REMOVE_ID
6586 packets. The packet is used to notify routers in the network
6587 about leaving entities. The ID removed will become invalid in
6590 * Added function silc_idlist_del_server into server. Removes and
6591 free's server entry from ID list.
6593 * silc_server_private_message function now checks, if we are router,
6594 that the destination ID really is valid ID, naturally.
6596 * In router when NEW_ID packet is received (for new client) the
6597 hash of the Client ID is saved in the ID Cache but the
6598 client->nickname is set to NULL, instead of putting the hash
6601 IDENTIFY command now also checks that client->nickname must be
6602 valid. If it is not if will request the data from the server who
6603 owns the client. Added new function
6604 silc_server_command_identify_check.
6606 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6607 to set the command to already allocated Command Payload.
6609 * Tested private message sending in router environment with two
6610 routers, two servers and two clients. Fixed minor bugs and now
6613 * Fixed segfault from client's NAMES command. Used to crash if
6616 * Forwarded packets must not be routed even if it is not destined
6617 to the receiver. Changed server code comply with this.
6619 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added `require_reverse_mapping' boolean value to ServerParams
6622 structure. If TRUE (not default) the server will require that
6623 the connecting host has fully qualified domain name.
6625 If the reverse mapping is not required and hostname could not be
6626 found the IP address is used as hostname.
6628 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Implemented version string checking to both client and server.
6631 The check is incomplete currently due to the abnormal version
6632 strings used in development version of SILC.
6634 * Changed all command functions in server to use the new
6637 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Changed char *data to unsigned char *data in ID Cache system to
6640 support binary data as ID Cache data. Changed code to support
6641 binary data in lib/silccore/idcache.c.
6643 * Renamed silc_server_packet_relay_command_reply to
6644 silc_server_command_reply as it is normal packet receiving
6645 function. Rewrote the function to accept command replys for
6646 servers and not only for clients.
6648 * Mark remote router always as registered server if we are connecting
6649 to it. Otherwise, commands sent by the router to us are ignored.
6651 * All ID List find routines now returns the ID Cache Entry pointer
6652 as well if requested.
6654 * WHOIS command works now in router environment, tested with two
6655 routers, two servers and two clients.
6657 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6658 in router environment (as it is almost equivalent to WHOIS) but
6659 hasn't been tested thoroughly. Added new functions:
6661 silc_server_command_identify_parse
6662 silc_server_command_identify_send_reply
6663 silc_server_command_identify_from_client
6664 silc_server_command_identify_from_server
6666 * Disabled route cache adding because adding two different ID's with
6667 same IP replaces the old cache entry thus giving wrong route.
6668 The entry->router->connection is always the fastest route anyway
6669 so route cache may not be needed. Of course, new routes maybe
6670 established after receiving the ID when the entry->router->connection
6671 might not be anymore the most optimal.
6673 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Add route cache for received ID for fast routing.
6677 * Added silc_server_packet_route to route received packet on router
6678 that is not destined to us.
6680 * Renamed silc_server_get_route to silc_server_route_get.
6682 * Added id_string and id_string_len fields into SilcServer to
6683 include encoded ServerID for fast comparing without excess
6684 encoding of the ID's.
6686 * Cleaned up WHOIS command on server side. Added following static
6689 silc_server_command_whois_parse
6690 silc_server_command_whois_check
6691 silc_server_command_whois_send_reply
6692 silc_server_command_whois_from_client
6693 silc_server_command_whois_from_server
6695 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6696 arguments in command replies. All command functions should be
6697 updated to use this macro.
6699 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Minor typo fixes on command reply handling on server.
6703 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Added silc_server_command_add_to_channel internal routine to add
6706 the client to the channel after router has created the channel and
6707 sent command reply to the server.
6709 * Added generic silc_server_send_command to send any command from
6712 * Use static buffer with ID rendering instead of duplicating data.
6714 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Fixed a channel user mode bug when joining to a channel server gave
6717 everybody channel founder rights, oops.
6719 * We mark ourselves as the router of the incoming server connection
6720 if we are router ourselves. This way we can check in some packet
6721 sending functions whether it is locally connected server. For
6722 incoming router connections we put NULL.
6724 * For router sending packets locally means now always sending the
6725 packet cell wide; to local clients and local servers. For normal
6726 server sending packet locally means sending it to only local
6729 * Fixed the JOIN command to really work in router environment. If the
6730 channel is created it is always created by the router. Router is
6731 also responsible of making the initial joining to the channel,
6732 sending JOIN notify to the sending server and distributing
6733 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6734 does not exist server doesn't do anything else but forward the
6735 command to the router which performs everything.
6737 * Added silc_server_send_channel_key function to send the Channel Key
6740 * Added silc_server_create_channel_key to create new channel key. The
6741 channel key is now re-generated everytime someone joins or leaves
6742 a channel, as protocol dictates. Note: channel->key_len is the
6745 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6748 packet_receive.[ch] to separate packet sending and receiving
6749 routines. The server.[ch] now includes everything else including
6750 actual packet processing (writing and reading data) and other
6753 Renamed silc_server_private_message_send_internal to
6754 silc_server_send_private_message. The routine is still though
6755 used only to relay private messages as server does not send
6756 private messages itself.
6758 Renamed silc_server_new_channel to silc_server_create_new_channel
6759 and added new function sicl_server_new_channel that handles the
6760 incoming New Channel packet. Added also new sending function
6761 silc_server_send_new_channel to send New Channel Payload.
6763 * Added new function silc_server_notify to process incoming notify
6764 packet to the server/router. Server may then relay the notify
6765 to clients if needed.
6767 * Added new function silc_server_new_channel_user to process incoming
6768 New Channel User packet. Router will redistribute the packet and
6769 send JOIN notify to its local clients and locally connected servers
6770 if needed. Normal server will send JOIN notify to its local client
6771 on same channel when received this packet. Added also corresponding
6772 sending function silc_server_send_new_channel_user to sent the
6775 * Added boolean route argument to send_notif_to_channel and
6776 packet_send_to_channel functions to attempt to route the packet
6777 if it is TRUE and send only locally if it is FALSE.
6779 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * silc_server_replace_id now broadcasts the received replace ID
6782 packet if it is not broadcast packet already. The router must
6783 broadcast to inform other routers about changed ID.
6785 * Added backpointer to server's router into SilcServer context in
6786 silcd/server_internal.h.
6788 * Fixed silc_server_packet_broadcast to send correct broadcast
6791 * The channel key is now distributed to the local client as soon
6792 as it is received from the router (in router environment) so that
6793 no other packet may be sent for the channel until client has
6796 * silc_server_remove_channel_user now broadcasts the received
6797 Remove Channel User packet if it is not broadcast packet already.
6798 The router must broadcast to inform other routers about removed
6801 * Added users field into SilcPacketContext that is a reference count
6802 of the context. One can increase the reference count by calling
6803 silc_packet_context_dup which is now changed to just increase the
6804 reference count instead of duplicating the data. The reference
6805 count is decresed by calling silc_packet_context_free that will
6806 free the data after the reference count hits zero.
6808 For now on the packet context and everything allocated into it
6809 (including the raw packet from network) must be freed by calling
6810 the new silc_packet_context_free function. Added also new function
6811 silc_packet_context_alloc that must be used now to allocate the
6812 context. This also means that if a routine is asynchronous from
6813 silc_[client/server]_packet_parse_type the packet context must
6814 be duplicated by calling silc_packet_context_dup. Otherwise it
6815 gets free'd after silc_[client/server]_packet_parse_type returns.
6816 Also, one must remember that if packet is duplicated then its
6817 reference count must be decresed by calling the free function as
6818 many times as it was duplicated.
6820 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6821 from both client and server.
6823 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Made joining to a channel working in router environment.
6827 * Cleaned up JOIN command on server side and create function
6828 silc_server_command_join_channel internal routine to make the
6831 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Changed silc_command_pending list to SilcDList. Also, added
6834 `ident' field to SilcServerCommandPending structure to identify
6835 the reply and to call correct callback.
6837 Added silc_server_command_pending_check function to replace the
6838 corresnponding macro. The silc_command_pending list is not
6841 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6842 to set identifier to previously allocated Command Payload. It
6843 is used to set identifier for command when resending Command
6846 * Added silc_command_payload_encode_payload to encode Command
6847 Payload buffer from SilcCommandPayload structure.
6849 * Added silc_argument_payload_encode_payload to encode Argument
6850 payload buffer from SilcArgumentPayload structure.
6852 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Changed WHOIS command to support router connection on server side.
6855 The whois request is always sent to router unless the server is
6856 standalone server. After server has received the reply from the
6857 router will it send the reply to the client.
6859 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6860 broadcast received broadcast packet. The function is used only
6861 by router. The broadcast packet is always sent to the router's
6864 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6865 render given ID to printable string, for log files for example.
6867 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Made basic router to router connections working. At least they
6870 can now connect to each other but nothing really works the way
6871 they are supposed - yet.
6873 * Added new initiator token to RouterConnection configuration
6874 file in silcd/serverconfig.[ch]. It is used to tell whether we
6875 are the initiator to the remote router or whether we'll expect
6876 the other end to connect.
6878 * Moved registering of listener task to silc_server_init, hence
6879 the server starts listenning as soon as it is run, even if it
6880 does not have connections to other routers. Let's see how well
6883 * Changed default connection retry timeouts for more suitable in
6886 * Removed cipher and such arguments from silc_idlist_add_client
6887 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6888 Added new function silc_idlist_add_data to add the keys and stuff
6891 * Added SilcIDListData structure and added it to SilcClientEntry
6892 and SilcServerEntry as their first field in the structure. This
6893 way we can explicitly cast the ID entries to the SilcIDListData
6894 structure and get common data for the entries. In past, we had
6895 to first check what type of connection it is and then cast it to
6896 correct ID entry type. Now, we can directly cast the opaque
6897 pointer to the SilcIDListData (no matter what ID entry it actually
6898 is) and get the data needed.
6900 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6903 in some circumstances even if threre were timeout tasks, though not
6904 IO tasks, but tasks anyway. Now fixed.
6906 * Defined SilcServerConnection structure to hold connection specific
6907 stuff about directly connected servers and routers. The definition
6908 is currently in silcd/server_internal.h. I thought about having
6909 a bit more important role fro this struct but for now it is used
6910 only when connecting to other server (or router actually).
6912 * Added connecting retry support in server when connecting to
6913 router(s). The retry feature implement exponential backoff
6914 algorithm. Also, added SilcServerParams structure to hold default
6915 parameters for server. For now, it include these retry settings
6916 and are hard coded. After server is moded to be as Silc Server
6917 Library this structure will be more important.
6919 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Changed client librarys channel->clients table to SilcList and
6922 changed code accordingly.
6924 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Changed client's channel table to SilcList and changed code
6927 accordingly. Also changed SilcChannelClientEntry to include back-
6928 pointer to the channel so that client entry can use that structure
6929 as list as well and we have fast cross-reference to the channel.
6930 This change dramatically decreased the complexity of channel
6931 handling with client entry and vice versa (removed one extra
6932 loop when searching for channel entry from many functions).
6934 * Changed server->sim from table to SilcDList and changed code
6937 * NAMES command can now be used from user interface. It will show
6938 the user list on the channel, neatly.
6940 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6941 Code now saves realname of the user if it becomes available.
6943 * Renamed configure.in to configure.in.pre and made ./prepare
6944 script to automatically add correct version string to
6945 configure.in which it creates from configure.in.pre.
6947 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * NAMES command reply now shows users mode with the nickname when
6952 * Moved silc_client_ch[u]mode[_char] functions from
6953 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6954 place sucks, they are utility functions and should be in some
6957 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6959 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6962 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Added TRQ (efficient deque and list library) into lib/trq. This is
6967 a very good list library that is currently used in the SILC. Defined
6968 SilcList API over the library because I didn't like the API very
6969 much. See lib/trq/silclist.h for the API and examples of how to
6970 use the API. Fixed various places in the code to use the new
6971 SilcList API. The SilcList is meant for lists that has a structure
6972 already defined as a list. It is not suitable to add just some
6973 context to the list (in TRQ, the context is the list actually).
6975 So, I defined SilcDList that can be used for the purpose where
6976 predefined list structure does not exit. This can be used as
6977 such list. Now some context just can be added to the SilcDList.
6978 Currently this list is not used in the SILC just yet, though there
6979 are a lot places where this can replace dynamically allocated
6980 tables and I will fix these places, later, to use SilcDList.
6981 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6982 and use TRQ internally).
6984 Also fixed some annoying warning messages that the original TRQ
6985 code generated. Also minor changes to TRQ's Makefile.in.
6987 * Added support for querying by Client ID to both WHOIS and
6988 IDENTIFY commands into server, as required by the protocol.
6990 * Removed method function pointers from SilcBuffer structure. They
6991 weren't used to anything and just increased the context size for
6992 no good reason. This change also made silc_buffer_alloc and
6993 silc_buffer_free functions inline functions.
6995 * Disabled command flooding detection support until it's fixed so
6996 that it accepts commands in but does not execute them more than once
6999 * Added silc_net_localhost(), to return local hostname, into
7000 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7001 that must be initialized before calling silc_client_init.
7003 * Added new function: silc_server_send_notify_on_channels to send
7004 notify messages to all channels client has joined. It is assured
7005 that the message is sent only once per client.
7007 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7008 lib/silcutil/silcutil.[ch] as silc_format function. The new
7009 function is generic and is used by server as well, not only by
7010 the logging routines.
7012 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7013 the provided version string was not acceptable. Added new function:
7014 silc_ske_check_version into lib/silcske/silcske.h. The function
7015 must be implemented by the application (client or server) and it
7016 does not reside in the SKE library. The function checks the version
7017 string remote end sent.
7019 * Added back pointers (to opaque context and to SilcSocketConnection)
7020 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7022 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7023 duplicate packet context structure.
7025 * Changed `notify' client operation to send same arguments as client
7026 receives from server except for ID's. ID's are mapped to correct
7027 ID entry and that is returned. Also, if channel entry is not sent
7028 by server but the notify is for channel the channel entry is sent
7029 to application (otherwise application doesn't know that it is for
7030 channel (library gets it from packet's Destination ID)).
7032 * Added silc_client_remove_from_channels into client library to
7033 remove a client from all channels it has joined to. Used when
7034 received SIGNOFF notify from server. Added also new function
7035 silc_client_replace_from_channels to replace old ID entry with
7036 new ID entry on all channels. Used when received NICK_CHANGE
7039 * Fixed ID Cache list handling in silc_idlist_get_client in
7040 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7041 to get (or query) client by ID.
7043 * Updated TODO list.
7045 * Added connection authentication status message defined by the
7046 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7047 support for these into the code in client and server side.
7049 * Added generic function silc_client_send_command to send any command
7050 with variable argument list. Application should use this function
7051 to send commands if the command functions provided by the library
7052 does not suite for the application's user interface needs.
7054 * Added new `failure' client operation. Application is notified about
7055 received failure packet if client is executing a protocol. In this
7056 case the protocol's execution has failed.
7058 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7059 is required by the protocol.
7061 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7062 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7065 * Added status flag to SilcSKE object to indicate realtime status
7066 of the SKE protocol.
7068 * Application receives now exactly same command reply arguments as
7069 the library receives from server. However, if ID is received the
7070 corresponding ID entry is returned to the application (eg. Client
7071 ID is mapped to correct SilcClientEntry entry and that is returned).
7072 Changed command_reply client operation due to this change.
7074 * Changed all ID's in commands and in command replys as ID Payloads.
7075 Change affected both client and server side codes.
7077 All ID's sent in SILC network (with execption of ID's in SILC
7078 Packet header) are sent in ID Payload to support variable length
7081 * Server now notifies nick changes and notifies all clients on
7082 the channels about the new nickname (about the new Client ID,
7085 * Implemented CMODE command to change channel modes. Supports all
7086 channel modes defined by the protocol specs except ban and invite
7087 lists. (Also, private channel key mode is supported but support for
7088 setting private channel key in client is missing, thus, this mode
7089 has no effect on client side (except that server requires that the
7090 client uses private channel key and normal channel traffic does not
7093 Also, invite mode works per se, but INVITE command does not work
7094 yet correctly, so you can set channel as invite only channel but
7095 inviting clients to the channel does not work (it is yet to be
7096 thought what's the best way to do it).
7098 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7099 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7100 Implemented CUMODE command to change user's mode on the channel.
7101 Supports all modes defined by the protocol specs.
7103 * Added NAMES command reply to return users modes on the channel.
7105 * Removed unnecessary and slow ciphers from lib/silccrypt.
7107 * Set SO_KEEPALIVE option to connection sockets by default.
7109 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7111 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7112 redefined the Notify Payload into protocol specs.
7114 * Added silc_id_payload_parse_id to get ID directly from raw
7117 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7120 accept searching by Client ID as well.
7122 * Added support for LEAVE and SIGNOFF notify types in client library.
7124 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7125 to parse ID Payload from raw data.
7127 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Added flags parameter into silc_ske_assemble_security_properties
7130 function in lib/silcske/silcske.[ch].
7132 * Changed notify client operation to fit better for notify messages
7133 sent by server. The notify payload received from server is now
7134 passed to the application (after parsing it to SilcNotifyPayload).
7135 It is application's responsibility to retrieve the arguments
7136 from the payload and show the message the way it wants. The message
7137 sent by server is implementation specific.
7139 * Changed public keys to comply with the protocol specification.
7140 Old public keys are not supported anymore and are not compatible.
7142 * Removed nickname from Channel Payload as the latest draft removed
7143 it. The client must resolve the nickname from the NAMES command
7144 reply received when it joined the channel.
7146 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7148 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Fixed some errors in protocol specification drafts.
7152 * Created lib/silccore/silcnotify.c to implement Notify Payload
7153 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7154 generic payloads described by protocol specifications. The file
7155 includes implementations for ID Payload and Argument Payload.
7157 * Changed Command Payload implementation to use the new Argument
7158 Payload. Changed command_xxxx_payload to command_payload_xxxx
7159 to comply with SILC coding conventions.
7161 * Added suppport for Argument Payload handling in Notify Payload
7162 implementation as protocol requires it. Added the new support
7163 into server and client lib as well.
7165 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7167 * Added support for multiple nicknames on same channel. [n] is
7168 added locally to the nickname if there are more than one same
7169 nicknames on the channel.
7171 * Server now sends all nicknames that matched WHOIS request.
7172 Client also shows the list received from server.
7174 * Added TOPIC command to client side. User can now set and show
7175 current topic on channel.
7177 * Added MOTD command to client and server. Also, server sends the
7178 motd when client connects to the server.
7180 * Changed version strings to comply ISO 8601.
7182 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7184 * Fixed protocol error handling in client library. It should now
7185 cope even if the SKE fails for some reason.
7187 * Made new protocol specification drafts for submitting to IETF.
7189 * Implemented TOPIC command to server in silcd/command.c.
7191 * Added two new notify types into lib/silccore/silcnotify.h:
7192 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7193 notify nickname change and topic setting/change on a channel.
7195 * API change of command_reply operation in client library. The
7196 application gets now the status type received from server as well.
7198 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7200 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7202 * Cras fixed and optimized the packet handling even further and
7203 it should work now. Minor change to the prototype of function
7204 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7206 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7208 * Added new function into lib/silcutil/silcschedule.[ch]:
7209 silc_schedule_with_fd to select() a specified fd. The function
7210 returns after timeout expires or data arrives or goes. The
7211 function is used by packet routines to wait that all data is
7212 received from network.
7214 * Fixed data reading from network in lib/silccore/silcpacket.c.
7215 The code now assures that all data is read from the fd and then
7216 continues packet processing. This was a bug fix since the code
7217 used to drop some data in some circumstances.
7219 * Added new function into lib/silcclient/client.[ch]:
7220 silc_client_start_key_exchange to start key exchange after
7221 connection has been established to server. The code internally
7222 now uses this funtion but its main purpose was to provide it
7223 for applications that perform their own connecting. After
7224 application has created a connection it merely calls this
7225 function to start the key exchange between client and server.
7226 The library takes care of everything else after that.
7228 Updated also lib/silcclient/README to explain the usage of
7231 * Do not send to application information that connection has
7232 been established. Application gets notified it by connect
7235 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7237 * Applied cras's patch to add silc_schedule_one function. The
7238 function runs scheduler once and returns.
7240 * Fixed the scheduler after cras messed it up. The timeout
7241 handling works now as it's supposed to work.
7243 * Added into lib/silccore/ silcnotify.h to include notify
7244 message types support. Changed silc_server_send_notify*
7245 functions, in server.[ch], to support those new notify types.
7246 Added the support for the notify types into client library,
7247 as well. Added new notify client operation into ops.h in
7250 * Changed silc_server_packet_send_to_channel to send normal
7251 packets instead of just channel message packets. The function
7252 is now used to send the notify packets to channels. It is not
7253 used to send channel message packets anymore, as server never
7256 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7257 va_arg()s as it seems to require it nowadays. I guess, if SILC
7258 is compiled with older va_arg() the new code should work anyway.
7260 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7262 * Splitted core library. Core library (lib/silccore) includes
7263 now only SILC protocol specific core (and common) components.
7264 Created new utility library (lib/silcutil) that includes more
7265 generic purpose stuff. The stuff for util library was taken
7266 from the old core library. This was minor and easy split.
7268 * Created SILC Client Library (lib/silcclient) that includes
7269 implementation of the SILC client without user interface. This
7270 was major move from silc/ directory. The code has been changed
7271 so that it is transparent towards the user interface. The
7272 silc/ directory includes now the same user interface as before
7273 and it uses the new client library. Read lib/silcclient/README.
7274 Basicly, the client library performs everything else related
7275 to SILC except user interface handling. Also, configuration
7276 files are considered to be part of user interface and library
7277 does not handle them.
7279 This change also changed a lot of structures, function naming etc.
7280 Most important change was that SilcClientWindow object was
7281 renamed to SilcClientConnection in the client library. Created
7282 also new file lib/silcclient/ops.h. Also added new files
7283 silc/local_command.[ch] and silc/client_ops.[ch].
7285 All these changes were made to make it easier for user interface
7286 designers to create what ever user interface for the SILC client
7289 It is also expected that the server will be moved to lib
7290 directory as well and SILC Server Library will be created;
7291 sometimes in the future.
7293 * Removed Local commands from lib/silccore/silccommand.h as
7294 they are application specific and new client library does not
7295 handle any of those anymore.
7297 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7298 old client implementation in silc/.
7300 * Added support for callback functions in SILC_LOG_* macros.
7301 Application can now set its own callbacks that will be called
7302 instead of using the default functions that will always print
7303 the debug messages to stderr (or stdout). Also, debugging can
7304 now be disabled by setting silc_debug to FALSE and re-enabled by
7305 setting it to TRUE. Note, that logging will still work even
7306 if debugging is disabled.
7308 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7309 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7310 silc_log_reset_debug_callbacks.
7312 * To enable debugging in silc client one must give now -d
7313 option on command line.
7315 * Changed silc_schedule_init to automatically allocate task queues
7316 if they are not allocated before calling it.
7318 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Added GMP 3.1 into math library.
7322 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7325 a channel in SILC network. The packet is used by servers and
7326 routers to notify other routers that user has left a channel.
7327 This little feature was missing until now. Added the feature
7328 to protocol specification as well.
7330 Added functions: silc_server_send_remove_channel_user and
7331 silc_server_remove_channel_user into server.[ch].
7333 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7334 lib/silccore/silcpacket.h. However, they are not implemented
7337 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Fixed joining to a channel and sending channel messages
7340 between server and router. The channel message sending should
7341 now work inside a cell.
7343 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7345 * Fixed the private message sending between server and router.
7346 The private message sending should now work inside a cell.
7348 * Added silc_server_replace_id into server.[ch] to replace
7349 existing ID in the SILC network.
7351 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7352 and silc_idlist_replace_server_id into idlist.[ch] in server.
7354 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Fixed the server to server connections. Server can again now
7357 connect to router. Router to router connections probably does
7360 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7362 * Added dynamic protocol registering support. Now protocols can
7363 registered and unregistered on the fly. Patch by cras.
7365 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7367 * Added lib/contrib directory to hold routines that some platforms
7368 don't have but are needed by SILC.
7370 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7371 into lin/contrib to provide getopt() and getopt_long() for
7372 those who don't have it.
7374 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7376 * Added AWAY command to client. When away message is set and
7377 client receives a private message packet the client automatically
7378 replies to the sender with the away message.
7380 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7381 bug seemed to be the cause of recent problems when compiling
7384 * Added version detection support to SKE protocol specification
7385 and added the new changes to the SKE implementation as well.
7386 There were other minor changes in the SKE protocol as well.
7388 Many changes in lib/silcske/silcske.[ch] and in
7389 lib/silcske/payload.[ch].
7391 * Added ^U functionality, clear input line. Patch from cras.
7393 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Mainly small bugfixes on core library. Fixed some debugging
7396 logging and buffer overflow in silclog.c.
7398 * Updated config.sub and config.guess on the distribution tree.
7400 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Added command lagging support in server. Client may execute
7403 commands now only once in two seconds.
7405 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * Optimized packet reception. MAC computation and checking is now
7408 also more optimized. A lot previously duplicated code is now
7409 used as generic by both client and server.
7411 * Fixed key pair generation in clientutil.c
7413 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Added into lib/silccore/silcbufutil.[ch] new function;
7416 silc_buffer_realloc.
7418 * Moved generic packet sending/encryption functions to
7419 lib/silccore/silcpacket.[ch] from client and server. Some
7420 rewriting of the functions.
7422 * Moved all generic packet reception/decryption functions to
7423 lib/silccore/silcpacket.[ch] from client and server. The
7424 packet processing is now much cleaner in both client and server.
7425 These were major changes in both client and server.
7427 * Created many common functions in server to do packet sending.
7428 Previously code were duplicated a lot, this has been removed
7431 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Rewrote major parts of the ID cache system. Don't know
7434 whether it is better now or not but at least the API is more
7437 * Major rewrite on ID cache stuff on client because of the ID
7438 cache API changes. Added idlist.c to client.
7440 * Also major rewrite on ID cache stuff on server as well.
7441 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7442 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7443 in hand, instead they are all put into the ID cache system now.
7444 All server_idlist_* routines uses ID cache now instead of
7445 traversing its own lists (those lists does not exist anymore).
7446 SilcIDList though still exists. Also, SilcXXXEntry's are
7449 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7451 * Finally made the SKE implementation compliant to the protocol
7452 specification. All mp integers are now binary encoded as
7453 opposed being HEX encoded.
7455 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7458 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7459 functions: silc_[encode/decode]_pem. Also added function
7460 silc_encode_pem_file to PEM encode with newlines ('\n') for
7463 * SILC public keys are now encoded either PEM or binary. Same
7464 option is for private keys as well. By default private keys
7465 are binary encoded and public keys PEM encoded. Silly HEX
7466 encoding were removed.
7468 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7469 function to create fingerprints.
7471 * Fixed a bug in SHA1; does not change the original data anymore.
7473 * Partly implemented INFO command on client and server side.
7474 Fixed CLEAR command. Changes to SERVER command; show current
7475 server(s) when giving command without arguments. Added
7476 VERSION command to client.
7478 * Added check to server that unregistered connections cannot
7479 execute commands (unless it is specificly allowed).
7481 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Fixed screen refresh.
7485 * Fixed channel joining bug from client. On some circumstances
7486 client tried to join to a channel it had already joined.
7488 * Added public key verification process into client's protocol.c.
7489 The client now verifies the public key from user and saves
7490 it into ~./silc/serverkeys/ directory.
7492 Added into: clientutil.[ch]: silc_client_verify_server_key.
7494 * Changed SKE protocol's silc_ske_initiator_finish function
7495 to accept callback function that verifies the received public
7496 key. Removed old silc_ske_verify_public_key function.
7498 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7501 silc_pkcs_private_key[_data]_set.
7503 * Made the password and public authentication more cleaner in
7504 server's protocol.c.
7506 * Removed historic and obsolete protocol `channel_auth' from
7507 both client and server.
7509 * Removed wrong way of sending command status messages from
7510 server to client in server's command.c. The old way violated
7511 protocol specification.
7513 Changes to silccore/silccommand.[ch]: removed
7514 silc_command_encode_status_payload -> not needed anymore,
7515 changed silc_command_encode_payload_va to accept extra
7516 argument on variable argument list. The argument type must
7517 now be provided to the function. Also, added new function:
7518 silc_command_encode_reply_payload_va which is same as
