1 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Improved the signal support in SILC Schedule. Added new
4 function silc_schedule_signal_call which is used by application
5 to mark a signal to be called. It is now safe to perform
6 any kind of tasks in signal callbacks since it is guaranteed
7 that the application specified signal callback is called
8 after the signal is over. Affected files are
9 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
11 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
13 * Added `name' field to SilcChannelPrivateKey to represent
14 application given name for the key. Moved also the context from
15 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
16 Added the `name' argument also to the function
17 silc_client_add_channel_private_key.
19 Added function silc_client_current_channel_private_key to set the
20 current channel private key in use.
22 Added "change" command to KEY command which can be used to change
23 the current channel private key. Bound the command also to
26 Also affected files lib/silcclient/client_channel.c,
27 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
29 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
31 * Added silc_rng_get_byte_fast function in to the
32 lib/silccrypt/silcrng.[ch].
34 * Changed the interface of silc_packet_assemble and the
35 silc_packet_send_prepare. If silc_packet_assmble is now
36 called the application does not call silc_packet_send_prepare
37 because the library will call it automatically. These
38 interfaces now also return a reference to the outgoing buffer
39 which includes the assembled packet, which the application can
40 use to encrypt the packet.
42 Affected files are lib/silccore/silcpacket.[ch],
43 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
44 silcd/packet_send.c, server_backup.c and packet_receive.c.
46 * Fixed a packet sending bug on very high load, where outgoing
47 packet queue wasn't handled correctly and packets got corrupted.
48 Affected files are lib/silcutil/*/silc*sockconn.c,
49 lib/silcclient/client.c and silcd/server.c.
51 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
53 * Added macro SILC_PACKET_DATALEN which can be used during
54 packet assembling to check whether the data to be added to
55 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
56 len is truncated until it fits it.
58 Added checks for maximum length of channel message payload and
59 private message payload also.
61 Added checks for maximum packet length in server and in
64 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
65 lib/silcclient/client.c, lib/silccore/silcchannel.c and
66 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
67 lib/silcclient/client_prvmsg.c.
69 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
71 * Added silc_server_packet_queue_purge call to the
72 silc_server_disconnect_remote to assure that all data in the
73 queue before disconnecting is sent to the network. Affected
76 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
78 * Added the deleting of server's own ID cache entry to the
79 silc_server_free function. Free also everything else that
80 has been allocated in silc_server_init. The affected file
83 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
85 * Added functions silc_parse_version_string, silc_version_to_num,
86 and silc_ske_parse_version to parse SILC protocol style version
87 strings. Affected files lib/silcutil/silcutil.[ch] and
88 lib/silcske/silcske.[ch].
90 * Added new configuration params: version_protocol, version_software
91 and version_software_vendor to specify what version the remote
92 host must at least be to be able to connect to server. The vendor
93 string can be regex matched too. Added new function
94 silc_server_connection_allowed to check maximum number of allowed
95 connections, and allowed versions for incoming connections.
96 Affected files are silcd/server.c, server_util.[ch] and
99 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * Added preliminary support for signals in scheduler. The
102 signals we care about are now blocked always when the scheduler
103 is locked. This way we can synchronise the use of signal with
104 scheduler. It is guaranteed that when signal occurs the scheduler
105 is not locked, and thus new tasks can be safely added to the
108 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
109 to silc_schedule_internal_init and silc_schedule_internal_uninit.
110 Added new platform specific routines
111 silc_schedule_internal_signals_[un]block and
112 silc_schedule_internal_signal_[un]register.
114 Added new functions to SILC Schedule API:
115 silc_schedule_signal_[un]register. Each signal that application
116 is going to use should be registered to the scheduler.
118 Affected files are lib/silcutil/silcschedule.[ch],
119 lib/silcutil/*/silc*schedule.c.
121 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
123 * Check for unauthenticated client and server in the
124 silc_server_new_client and silc_server_new_server functions.
125 Affected file silcd/packet_receive.c.
127 * Added function silc_string_is_ascii to check whether given
128 string is 7-bit ASCII string. Affected files are
129 lib/silcutil/silcutil.[ch].
131 * Added function silc_id_is_valid_server_id into the
132 silcd/serverid.c and added checking for valid Server ID's in
133 silc_server_new_server. The Server ID must always be based
134 on the server's public IP address.
136 * Added logging of DISCONNECT packet message in the server.
137 Affected file silcd/server.c.
139 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
141 * Changed all library interfaces that use Global RNG to also
142 accept SilcRng as argument. Affected files are
143 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
144 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
145 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
146 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
149 * Added function silc_pkcs_generate_key to the
150 lib/silccrypt/silcpkcs.[ch] for applications so that they
151 don't need to do pkcs->pkcs->init calls anymore.
153 * Remove SilcSocketConnection from the SFTP API since it really
154 wasn't needed there. The application has the information
155 saved in its contexts anyway and the SFTP layer doesn't need
156 know about it. Affected files lib/silcsft/silcsftp.h and
157 lib/silcsftp/sftp_[server/client].c.
159 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
160 The SilcSimContext is not SilcSim.
162 * Fixed possible buffer overflows in silc_id_render in the
163 lib/silcutil/silcutil.c.
165 * On EPOC the global crypto module lists are not used at all
166 in the crypto library. Added support for using the constant
167 algorithm list on EPOC. Affected files are
168 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
171 * Fixed the handling of third parameter of KICKED notify, since
172 it was mistakenly updated to SILC Protocol 1.0 even though it
173 is to be included in 1.1. Since it is not in 1.0 it is not
174 mandatory, and this fix now handles it only if it is provided,
175 and it is not error if it is not provided. Affected file
176 lib/silcclient/client_notify.c.
178 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
180 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
181 client. Affected file irssi/src/silc/core/client_ops.c.
183 * Merged with Irssi 0.8.4 from irssi.org CVS.
185 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
187 * Check for valid socket connection in client entries before
188 sending any messages. Fixes a crash, but doesn't fix some
189 other underlaying bug that is lurking there. Affected
190 file silcd/packet_send.c.
192 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
194 * $usermode, $cumode and $cumode_space expandos shouldn't do
195 anything with non-SILC server records. Affected file
196 irssi/src/silc/core/silc-expandos.c
198 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
200 * Fixed the silc_net_check_[host/local]_by_sock to support
201 IPv6 bound sockets as well. Now they can return IPv6 addresses
202 as well. Affected file lib/silcutil/silcnet.c.
204 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
205 Affected lib/silcutil/unix/silcunixnet.c.
207 * Fixed ID rendering (at least on some platforms, not NetBSD)
208 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
210 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
212 * Added silc_hash_public_key and silc_hash_public_key_compare
213 functions to be used with SilcHashTable. They can be used to
214 hash public keys and compare public keys in hash table. Affected
215 file lib/silcutil/silcutil.[ch].
217 * Added support for specifying multiple public keys for Client
218 connection section in server configuration file. This makes it
219 possible to accept multiple public keys from same host, or to
220 make a section that accepts any incoming host, and have the
221 accepted public keys listed in the section.
223 Added functions silc_sever_[find/get]_public_key, added the
224 support for this actually to all connection sections but only
225 the Client section is currently allowed to specify multiple
228 Affected files are silcd/server.c, server_internal.h,
229 command.c, protocol.c, server_util.[ch], packet_receive.c.
231 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
233 * Merged Irssi 0.8.2 from irssi.org CVS.
235 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
237 * If silc_debug is TRUE, also output standard logging messages
238 to stderr with the debug output.
240 Made silc_log_reset_all() flushing all channels before returning.
241 Also fixed some documentation typos.
243 Affected files are lib/silcutil/silclog.[ch].
245 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
247 * Fixed the server to check correctly the amount of connections
248 from single host, by checking also the type of the connection.
249 Fixed also the comparison of number of connections and number
250 of allowed connections. Affected files are silcd/server.c,
253 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
255 * Fixed the USERS command reply to save the user's mode on the
256 channel as well. Fixed JOIN command reply to check whether a
257 client is on channel already and not join it twice. Affected
258 file lib/silcclient/command_reply.c.
260 * Added new file silc-expandos.c into irssi/silc/core/ to return
261 various stuff for various signal for the statusbar etc. updating.
262 Now Irssi SILC client prints channel user modes etc. on the
265 * The user mode (like server/router operator changes) is now shown
266 on the Irssi SILC client's statusbar. The affected files are
267 irssi/src/silc/core/client_ops.c, silc-expandos.c.
269 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
271 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
272 to SILC_SCHEDULE_[UN]LOCK macros.
274 * Added more error printing to logs in server code. Affected
275 files silcd/server.c and silcd/protocol.c.
277 * Fixed -S option parsing in Irssi SILC Client. Affected file
278 irssi/src/silc/core/silc-core.c.
280 * Added silc_buffer_alloc_size function. Affected file is
281 lib/silcutil/silcbuffer.h.
283 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
285 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
286 constants. Affected files in
287 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
290 * Changed the internal SFTP Memory FS table to const. Affected

293 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
295 * Fixed the buffer formatting and unformatting routines to
296 check the size of 64 bits types with sizeof(). Affected
297 file is lib/silcutil/silcbuffmt.c.
299 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
301 * Removed 0.6.x backwards support.
303 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
305 * Changed all integer type names:
306 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
307 to avoid collisions with other libraries using same type names
310 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Added `prefer_ipv6' argument to the functions
313 silc_net_gethostbyname[_async]. If it is TRUE it will return
314 IPv6 address over IPv4. If FALSE IPv4 address is returned
315 even if IPv6 address was found. Affected files
316 lib/silcutil/silcnet.[ch].
318 * Added support silc_net_create_connection[_async] to fallback
319 to IPv4 address if IPv6 address could not be used (like if
320 it doesn't work on a specific system). Affected file in
321 lib/silcutil/unix/silcunixnet.c.
323 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

329 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
331 * Added automatic extern "C" { ... } for C++ compilers so the
332 application does not need to define them. Affected file
333 includes/silcincludes.h.
335 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
336 old name went against naming convention. Applications now
337 include "silcclient.h" instead of "clientlibincludes.h".
338 Removed includes/clientlibincludes.h, it is redundant now.
340 * Renamed includes/version.h to silcversion.h.
342 * Added really preliminary support for OS/2 into the util
343 library. Only thread & mutex API is implemented, others
344 are still to be implemented. Created the lib/silcutil/os2/
345 directory. Created also file includes/silcos2.h.
347 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
349 * Added preliminary BeOS support into the util library.
350 Created lib/silcutil/beos/, and implemented all the needed
351 functions to support SILC on BeOS. Created also file
354 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
356 * Added proper initializations to silc's irssi code, so it's
357 now possible to load it as module. Affected files
358 irssi/src/silc/core/silc-core.c,
359 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
361 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
363 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into

367 docs from all kinds of filenames. Affected files are
368 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
370 * ROBOdoc documented lib/silcutil/silcmemory.h.
371 Added also new function silc_memdup.
373 * Removed lib/silcutil/silcbufutil.h and moved those routines
374 to the lib/silcutil/silcbuffer.h.
376 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
378 * Added `user_count' to the SilcChannelEntry which now tells the
379 number of users on the channel. The user count is now saved
380 in normal server of global channels as well. Affected files
381 silcd/server.c, idlist.h, packet_receive.c and command.c.
383 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
384 include file utility functions.
386 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
387 instead of calling directly OS routines.
389 * Fixed NICK change printing in Irssi SILC Client. Fixed
390 KICKED notify printing in Irssi SILC Client. Affected file
391 irssi/src/silc/core/client_ops.c.
393 * Fixed a NICK change bug in client library, to not recreate the
394 client_entry->channels hash table everytime nick is changed.
395 Affected file lib/silcclient/client.c.
397 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
399 * ROBOdoc documented the lib/silcske/silcske.h, and improved
400 the SKE interface a bit.
402 * Fixed padding problem in PKCS#1. The padding was not actually
403 random since the random number generator was used incorrectly.
404 This security bug affects only when encrypting with PKCS#1, and
405 it is not currently used at all in SILC. SILC only use signing
406 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
408 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
410 * Rewrote the notify handling in Irssi SILC client to not call
411 the events as signals. Fixes problems with Perl support.
412 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
414 * Send the auto-nicking NICK command in client library with
415 little timeout after connecting. The affected file is
416 lib/silcclient/client.c.
418 * Added following new config file settings:
419 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
420 key_exchange_timeout, conn_auth_timeout, connections_max,
423 Implemented all the new config settings handling in the server.
425 Optimized the use of SKE Mutual flag usage. Use it only
426 if connection authentication protocol is not based in public
429 Renamed all SilcServerConfigSection* to SilcServerConfig*
430 to have a bit shorter names.
432 Affected files silcd/serverconfig.[ch], server.[ch], and
435 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
437 * Cleaned up the listening sockets code, preparing for the rehash
438 support. Affected file is silcd/server.c.
440 * Fixed some output messages. Affected files are silcd/silcd.c,
443 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
445 * Create lib/doc/silcrng_intro.html document as introduction
446 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
448 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
450 * Fixes to the silcd config template. Affected file is
451 doc/example_silcd.conf.in.
453 * Removed type casts from silc_calloc(), conforming to the
454 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
456 * Removed param_name member from client, server, and router
457 section structs, now identifying the param directly.
459 Added CONFIG_FREE_AUTH macro in config file parsing.
461 Affected files are silcd/serverconfig.[ch].
463 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
465 * Fixed command line parameter handling. All SILC initialization
466 is now done in silc_core_init() which also fixes autoconnecting
469 Affected files irssi/src/silc/core/silc-core.c,
470 irssi/src/fe-text/silc.c.
472 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Added new configuration options and blocks:
475 keepalive_secs, reconnect_count, reconnect_interval,
476 reconnect_interval_max, reconnect_keep_trying and
477 require_reverser_lookup. Added ConnectionParam block, and
478 implemented the connection parameters when connecting as
479 initiator and when accepting connections as responder.
481 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
482 whether given configuration value has been given already.
484 Affected files silcd/serverconfig.[c], server.[c].
486 * Splitted the doc/example_silcd.conf.in. Separated the crypto
487 algorithm parts and created new file silcalgs.conf, that
488 is now included from the example_silcd.conf.in.
490 * Optimized the silc_server_connect_to_router_second to take
491 the connection configuration object from the SilcServerConnection
492 object instead of finding it during the connecting phase.
493 Added the configuration object to SilcServerConnection struct.
494 Affected files silcd/server_internal.h, server.c.
496 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
498 * Add the client on channel after it was resolved at the
499 channel message receiving, and it was not already on the
500 channel. Affected file lib/silcclient/client_channel.c.
502 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
504 * Fixed the public key authentication to allocate always the
505 destination signature buffer instead of using static buffer.
506 Affected file silcd/protocol.c.
508 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
510 * Unified the serverconfig.[ch]'s helper function interface.
511 Affected file silcd/serverconfig.[ch].
513 * Removed doc/example_silc.conf.in since it is redundant.
514 The make install will now install irssi/silc.conf file.
516 * Added new Passphrase and Publickey authentication methods to
517 config file, allowing both public key and passphrase based
518 authentication to be set at the same time.
520 Added `prefer_passphrase_auth' setting in config file which
521 can be used to set to prefer passwd auth if both passwd and
522 public key is set. If not set, public key is preferred.
523 This has effect only when being initiator (responder will try
526 Added support for authentication with passphrase and public key
527 at the same time. The passphrase is tried first always since
528 it is faster to check.
530 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
532 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
534 * Merged the new SILC Config library, with the server parsing
535 support. Read the header file silcconfig.h or the toolkit
536 documentation for the news. Affected files are
537 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]

540 silcd/serverconfig.[ch] silcd/silcd.c.
542 * Fixed some silclog documentation. Affected file is
543 lib/silcutil/silclog.h.
545 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
547 * The silc_cipher_register, silc_hash_register and
548 silc_hmac_register now checks if the object to be registered
549 is registered already. Affected files are
550 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
552 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

599 is changed and +k mode is set in the channel. Affected file
600 irssi/src/silc/core/silc-channels.c.
602 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
603 SILC_LOG_WARNING to give out Warning and not Error. Affected
604 file lib/silcutil/silclog.c.
606 * Fixed the channel message payload decryption in the function
607 silc_channel_message_payload_decrypt to not modify the original
608 buffer before it is verified that the message decrypted
609 correctly. Otherwise, next time it is called with correct
610 channel key it won't encrypt since the payload is corrupted.
611 Affected file lib/silccore/silcchannel.c.
613 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Do not constantly resize the window. A fix patch by cras.
616 Affected file irssi/src/fe-text/screen.c.
618 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
621 Affected file lib/silcutil/silcnet.c.
623 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
625 * Fixed a bug in hash table internal routine for traversing
626 the table with foreach callback. The current entry may
627 become invalid in the callback but it was referenced after
628 the callback returned.
630 Do not allow auto rehashing of hash table during the
631 silc_hash_table_foreach operation, for same reasons as it is
632 not allowed for SilcHashTableList. Affected files are
633 lib/silcutil/silchashtable.[ch].
635 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
637 * Defined DLLAPI into silcincludes.h and silcwin32.h for
638 Win32 DLL. extern's in header files are now declared with
641 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Fixed private message handling. It used some old code that
644 caused the client to crash. Affecte file is
645 lib/silcclient/client_prvmsg.c.
647 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Added function silc_client_add_channel,
650 silc_client_replace_channel_id, and removed functions
651 silc_client_new_channel_id and silc_idlist_get_channel_by_id
654 * Added cross reference of the joined channels to the
655 SilcClientEntry, and changed the SilcChannelEntry's
656 users list to SilcHashTable. The affected files are
657 lib/silcclient/idlist.[ch].
659 * Fixed a bug in hash table tarversing. While the hash table
660 is traversed with SilcHashTableList the table must not be
661 rehashed. It is now guaranteed that auto rehashable tables
662 are not rehashed while tarversing the list. Also defined that
663 silc_hash_table_rehash must not be called while tarversing
664 the table. Added function silc_hash_table_list_reset that must
665 be called after the tarversing is over. The affected files are
666 lib/silcutil/silchashtable.[ch].
668 * Changed all hash table traversing to call the new
669 silc_hash_table_list_reset in server and in client library.
671 * Added function silc_client_on_channel to return the
672 SilcChannelUser entry if the specified client entry is joined
673 on the specified channel. This is exported to application as
674 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
676 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Fixed founder regaining problem with JOIN command on normal
679 server. The notify for mode change must be sent always and
680 not only if !cmd->pending. Affected file silcd/command.c.
682 * Fixed the WHOWAS command's reply sending to support the
683 lists correctly. Affected file silcd/command.c.
685 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
687 * When sending JOIN command to router for processing the
688 sender's old command identifier was not saved back to the
689 sender's command context, fixed now. The affected file is
692 * Create the key in JOIN command of the router did not return
693 the channel key, added check for this. Affected file is
696 * Fixed a channel ID update bug in JOIN command reply. Do
697 not directly upgrade the ID but call the function
698 silc_idlist_replace_channel_id if the ID was changed.
699 Affected file silcd/command_reply.c.
701 * Fixed memory leaks from command calling if it would fail.
702 Affected file silcd/command.c.
704 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Applied patches from cras:
708 Memory leak fixes around libaries, irssi window resize fix,
709 new silclist.h and silcdlist.h, all extern inline changed to
712 * Removed dotconf from lib/dotconf, not needed anymore.
714 * Removed TRQ from lib/trq, not needed anymore.
716 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
717 with server connections. Later this will be configurable
718 in config file after new config file is done. Affected file
721 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
723 * Fixed a crash in server related to channel announcements.
724 Affected file silcd/server.c.
726 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Fixed memory leaks in silc_server_create_new_channel*
729 functions. Affected file silcd/server.c.
731 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
732 which ID was changed. This way the router will send the
733 user list for the channel again, and server won't be in
734 desync in some rare circumstances. Affected file is
735 silcd/packet_receive.c.
737 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Check for NULL socket pointer in the function
740 silc_server_packet_send_to_channel_real. Affected file

744 list. Affected file silcd/packet_receive.c.
746 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
748 * Fixed some header addition to Toolkit distribution in
749 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
751 * Added lib/silcclient/client_ops_example.h as an template
752 file for application programmers to quickly start using
753 the SilcClientOperation functions in their application.
754 Updated the lib/silcclient/README as well to tell about this
755 nice file made available.
757 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
759 * Call silc_server_remove_from_channels when removing client
760 entry when NO_SUCH_CLIENT_ID was received. Affected file
761 is silcd/command_reply.c.
763 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
765 * Added server & router operator statistics updating. Affected
766 file silcd/packet_receive.c and silcd/command.c.
768 * Fixed the SERVER_SIGNOFF notify handling on normal server
769 not to save the history information for clients. Same was
770 fixed earlier in remove_clients_by_server function, but not
771 here. Affected file silcd/packet_receive.c.
773 * Raised the default connection-retry count from 4 to 7 in
774 server. Affected file silcd/server.h.
776 * Cancel any possible reconnect timeouts when we start the
777 key exchange. Affected file silcd/server.c.
779 * Do not reconnect on connection failure when SCONNECT was
780 given. Affected files silcd/server.[ch].
782 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
784 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
786 * Fixed the NICK command to always give the unformatted
787 nickname to the one giving the NICK command. If unformatted
788 nickname is cached already it will be formatted and the
789 local entry will always get the unformatted nickname.
790 Affected file lib/silcclient/idlist.c.
792 * Fixed some double frees from client library commands.
793 Affected file is lib/silcclient/command.c.
795 * Fixed CUMODE command in server to assure that no one can
796 change founder's mode than the founder itself, there was a
797 little bug. Affected file silcd/command.c.
799 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
801 * Removed the SilcClientCommandDestructor from the client
802 libary, it is not needed anymore. Affected files are
803 lib/silcclient/silcapi.h, command[_reply].[ch],
804 client_notify, idlist.c.
806 * Fixed GETKEY command to first resolve client, and then
807 resolve the server only if the client was not found, instead
808 of resolving both at the same time. Affected file is
809 lib/silcclient/command.c.
811 * Added silc_client_start_key_exchange_cb and lookup the
812 remote hostname and IP address before starting the key
813 exchange with server. The affected file is
814 lib/silcclient/client.c.
816 * The server's public key is now saved using the IP address
817 of the server and not the servername for the filename.
818 The hostname public key filename is checked as an fall back
819 method if the IP address based filename is not found.
821 Fixed the GETKEY command to save the fetched server key
824 Print the remote server's hostname now when new key is
825 received during connection process. Affected file is
826 irssi/src/silc/core/client_ops.c.
828 * Return always our own public key to the client if it asks
829 for it with GETKEY command. Affected file silcd/command.c.
831 * Removed the use_auto_addr variable from default config
832 file since it was in wrong section. Affected file is
835 * Fixed TOPIC_CHANGE notification to not route it when it
836 was sent using silc_server_send_notify_to_channel function.
837 Affected file silcd/command.c.
839 * Fixed silc_server_send_notify_kicked to send the kicker's
840 Client ID also, it was missing. Affected files are
841 silcd/command.c, silcd/packet_send.[ch].
843 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
845 * Do not save client history information in SERVER_SIGNOFF.
846 Fixes the bug in normal server that it does not detect
847 the client becoming valid after the server becomes back
848 online. Affected file silcd/server_util.c.
850 * Added `sock_error' field into the SilcSocketConnection
851 context. When error occurs during socket operation (read
852 or write) the error is saved. Added also new function
853 silc_socket_get_error to return human readable socket error
854 message. Affected files are lib/silcutil/silcsockconn.[ch],
855 lib/silcutil/unix/silcunixsockconn.c, and
856 lib/silcutil/win32/silcwin32sockconn.c.
858 * The server now prints the socket error message in the
859 signoff for client. Affected file silcd/server.c.
861 * Fixed the `created' channel information sending from router
862 to server in JOIN command. Checks now whether the channel
863 really was created or not and set it according that.
865 Fixed the JOIN command to use the client entry's current
866 ID during the joining procedure instead of the one it sent
867 in the command (it is checked though), since it can change
868 between the packet processing and command processing, and
869 would just case unnecessary pain in the client end. Affected
870 file silcd/command.c.
872 * Fixed a channel key payload sending to use correct channel
873 ID when the server was forced to change the channel's ID by
874 router. Router sent the key payload with the old Channel ID.
875 Affected file silcd/packet_receive.c.
877 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
879 * Call silc_server_save_channel_key only if the key payload
880 was provided in the JOIN command's command reply. Affected
881 file silcd/command_reply.c.
883 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
885 * Fixed silc_mp_sizeinbase to return the value correctly with
886 MPI. Affected file lib/silcmath/mp_mpi.c.
888 * Fixed the stop_server signal to correctly stop the scheduler
889 and gracefully stop the server when SIGTERM or SIGINT signals
890 are received. Affected file silcd/silcd.c.
892 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
894 * Simple handling of TERM and HUP signals. Also added some log
895 flushing call around. Affected file is
898 * Fixed small bugs in silclog.c. Now buffering output will take
899 effect after 10 seconds since startup: This will ensure that
900 no important startup messages are lost. Also output redirection
901 will preserve original format ([Date] [Type] message).
902 Affected file is lib/silcutil/silclog.c.
904 * Added two options to the config file, in the logging section:
905 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
906 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
908 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
910 * Do not print the warning about log files not being initialized
911 more than once to avoid excess logging. Affected file is
912 lib/silcutil/silclog.c.
914 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
915 the SIM copying in make install in Makefile.am.pre.
917 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
919 * Rewritten silclog APIs. Globally interesting changes follows:
920 silc_log_set_files() changed to silc_log_set_file().
921 silc_log_set_callbacks() changed to silc_log_set_callback().
922 ROBOdoc documented silclog header file.
923 SilcLogCb now returns bool to wether inihibit the default
924 handler or not (to keep the old behaviour return always TRUE).
925 The new APIs should also fix the problem of the
926 silcd_error.log file that was written in the current directory.
929 Log files streams will remain opened after silc_log_set_file()
930 call, means less CPU usage notably on high traffic servers.
931 File streams are now full buffered, and flushed to the disk
932 every 5 minutes, lesses HD activity and CPU usage.
933 Messages can be redirected, allowing admins to configure
934 one single logfile for all server messages.
935 the silc_log_quick global variable to activate fast-logging.
936 Affected files lib/silcutil/silclog.[ch]
938 * Changed some code to conform new silclog APIs. Affected
939 files are doc/example_silcd.conf.in, silcd/server.c
940 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
943 * Fixed a memory leak that could occur in some situations.
944 Affected file silcd/serverconfig.c.
946 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Added the silc_client_del_client to remove the client from
949 all channels as well. Affected file lib/silcclient/idlist.c.
951 * Fixed the client library to correctly remove the client
952 from all channels when the client entry is being destroyed.
953 Affected file lib/silcclient/client_notify.c, command.c.
955 * Added auto-nicking support to the client library. If the
956 applicatio now sets client->nickname it will be sent to the
957 server after connecting by the library. This way for example
958 SILCNICK (or IRCNICK) environment variables will have effect
959 and always change the nickname automatically to whatever
960 it is wanted. Affected file lib/silcclient/client.[ch].
962 * Renamed silc_server_command_bad_chars to the
963 silc_server_name_bad_chars and moved it to the
964 silcd/server_util.[ch]. Added also new function
965 silc_server_name_modify_bad to return nickname that
966 includes bad characters as new nickname without those
967 bad characters. This check and modify is now used in
968 silc_server_new_client when the username is initially set
969 as nickname, so it must be checked to be valid nickname.
970 Affected file silcd/packet_receive.c.
972 * The nickname length is now taken from the packet for real
973 and not trusted to strlen() since it clearly can return
974 wrong length for nickname including bad characters. This
975 also applies to channel names. Affected file silcd/command.c.
977 * Removed the lib/silcsilm/modules directory. Modules are now
978 compiled into the lib/silcsim. Fixed the copying of the
979 modules to follow symbolic links in Makefile.am.pre.
981 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
983 * Fixed silc_string_regexify list creation. Fixes bugs with
984 BAN and INVITE commands in server. The affected file is
985 lib/silcutil/unix/silcunixutil.c.
987 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Removed the command destructor entirely from the server's
990 command and command reply routines. It is not needed, and
991 its usage was buggy and caused crashes. Affected files are
992 silcd/command[_reply].[ch].
994 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Cancel protocol and NULL sock->protocol if timeout
997 occurred during protocol. Affected file silcd/server.c.
999 * Cancel protocol timeouts always before calling the final
1000 callback, to assure that after final callback is called
1001 no other state will be called for the protocol anymore.
1002 Affected file silcd/protocol.c.
1004 * Print error log if incoming connection configuration could
1005 not be found. Affected file silcd/server.c.
1007 * Fixed JOIN command to correctly save the founder mode
1008 to the client on normal SILC server, when the channel
1009 was created by the router. Affected file silcd/command.c.
1011 * Fixed LIST command (hopefully) to send correct reply
1012 packets. Affected file silcd/command.c.
1014 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * The silc_packet_receive_process now returns FALSE if the
1017 read data was invalid packet, and TRUE if it was ok.
1019 The server now checks that if unauthenticated connection
1020 sends data and its processing fails the server will close
1021 the connection since it could be a malicious flooder.
1023 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1025 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1027 * Make sure the warning about error opening a log file is
1028 printed only once and not everytime it fails (produces
1029 too much useless log). Affected file lib/silcutil/silclog.c.
1031 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1033 * Made the silc_server_daemonise() function more readable.
1034 Affected file silcd/server.c.
1036 * Pid file is now optional, the user may comment it out from
1037 the config file. Removed define SILC_SERVER_PID_FILE, we
1038 don't need a default any longer. Affected file
1039 configure.in.pre, lib/Makefile.am.pre.
1041 * Make some use of the pid file. The server now dies at startup
1042 if it detects a valid pid file on his path. The server would
1043 die anyway in this circumstance, because of the bind() failure.
1044 Affected file silcd/silcd.c.
1046 * No longer compiling lib/dotconf.
1048 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Fixed JOIN command parsing not to crash. Affected file
1051 lib/silcclient/command.c.
1053 * Fied the NICK_CHANGE notify to add the new client entry
1054 even it is resolved. This removes an <[unknown]> nick
1055 thingy bug in the client. Affected file is
1056 lib/silcclient/client_notify.c.
1058 * Do not try to allocate 0 bytes (efence does not like it)
1059 in lib/silccore/silccomand.c when encoding payload.
1061 * Do not take IRCNICK as nickname in Irssi SILC client since
1062 it is not possible to set nickname before hand connecting
1063 the server (TODO has an entry about adding auto-nicking
1066 * Changed the silc_server_command_pending to check whether
1067 there already exists an pending entry with the specified
1068 command, command identifier and pending callback. This is
1069 to fix IDENTIFY and WHOIS related crashes that may register
1070 multiple pending commands with same identifier. Affected
1071 file silcd/command.c.
1073 * Fixed the server to reconnect to the router even if it
1074 was already reconnecting and EOF was received. This to
1075 fix a possibility that the server wouldn't ever try to
1076 auto-reconnect to the router. Affected file silcd/server.c.
1078 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Fixed the server's password authentication to use the
1081 length of the locally saved password, and not the one
1082 sent in the packet. Affected file silcd/protocol.c.
1084 * Fixed same password authentication problem in the
1085 Authentication Payload handling routines in
1086 lib/silccore/silcauth.c.
1088 * Yet another password authentication problem fixed with
1089 channel password handling in silcd/command.c.
1091 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * If first character of string in silc_parse_userfqdn is '@'
1094 then do not parse it. Affected file is
1095 lib/silcutil/silcutil.c.
1097 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1099 * Fixed minor bug in IDENTIFY command reply sending, which
1100 caused various weird problems during JOIN when it was
1101 resolving names for users. Affected file silcd/command.c.
1103 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Fixed the IDENTIFY command reply sending to chech better valid
1106 clients. It was possible to send incomplete list of replies.
1107 Affected file silcd/command.c.
1109 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * Added silc_client_command[s]_[un]register functions now to
1112 dynamically register the commands in client library. Removed
1113 the static table of commands. This allows the client library
1114 to call commands without causing the application to know about
1115 what commands library has called.
1117 Removed the INFO command reply kludge to detect when the command
1118 was called by library. Now library use its own command reply
1119 function for INFO command.
1121 Added function silc_client_command_call to call a command.
1122 Application can use it to call command, not access the structure
1125 Now all commands that are sent by the client library (not
1126 explicitly sent by application) use own command reply functions.
1128 Affected files around lib/silcclient/ and in
1129 irssi/src/silc/core/.
1131 * Fixed the WHOIS command reply sending to chech better valid
1132 clients. It was possible to send incomplete list of replies.
1134 Fixed the WHOIS and IDENTIFY to send the request to router
1135 if normal server did not do it and did not find any results.
1137 Affected file silcd/command.c.
1139 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Moved the internal data from SilcClient context into its
1142 own file, not accesible to application. Affected files
1143 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1144 and other files in client library.
1146 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Added doc/examples installation target in Makefile.am.pre.
1151 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1153 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1154 commands the found client entry will be removed from the
1155 cache, after notifying application about the error. Affected
1156 file lib/silcclient/command_reply.c.
1158 * Changed the /MSG to check for exact nickname user gave, and
1159 not let `nick' match `nick@host' if it is only one found. Now,
1160 user must type the exact nickname (like nick@host2) even if
1161 there are no more than one same nicks found. This is to avoid
1162 a possibility of sending nickname to wrong nickname since
1163 `nick' could match `nick@host'. Affected file is
1164 irssi/src/core/silc-servers.c.
1166 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Do not print "you are now server operator" or similar when
1169 giving /away command. Affected files are
1170 irssi/src/silc/core/client_ops.c, silc-servers.h.
1172 * Made the silc_server_command_pending_error_check to send
1173 the same command reply payload it received back to the
1174 original sender of the command. This way all arguments
1175 that was received by the server will be received by the
1176 client too. Affected file silcd/command.c.
1178 * Added the silc_idcache_add to return the created cache entry
1179 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1181 * Add global clients to expire if they are not on any channel.
1182 This is because normal server will never know if they signoff
1183 if they are not on any channel. The cache expiry will take
1184 case of these entries. This is done by normal servers only.
1185 The affected files are silcd/command_reply.c,
1186 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1188 * If server receives invalid ID notification for WHOIS or
1189 IDENTIFY and the ID exists in the lists, it is removed.
1190 Affected file silcd/command_reply.c.
1192 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1193 in client then client entry that it matches is searched and
1194 the nickname is printed on the screen for user. Affected
1195 file irssi/src/silc/core/client_ops.c.
1197 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Use cache entry expire time in the LIST command reply to
1200 purge old entries from the cache after the LIST command
1201 reply has been received. This way we don't have non-existent
1202 entries in the cache for too long. Affected file is
1203 silcd/command_reply.c.
1205 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1207 * If we are normal server, and we've not resolved client info
1208 in WHOIS or IDENTIFY from router, and it is global client,
1209 we'll check whether it is on some channel. If it is not
1210 then we cannot be sure about its validity and will resolve it
1211 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1212 file silcd/command.c.
1214 * Search channel by name (if possible) rather than by ID
1215 in IDENTIFY command's command reply. Affected file is
1216 silcd/command_reply.c.
1218 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1220 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1221 Updated specs and implemented it. Affected file silcd/command.c,
1222 silcd/packet_send.c and silcd/packet_receive.c.
1224 * Implemented the <founder auth> payload handling in the JOIN
1225 command. If provided all conditions for channel joining
1226 except requirement to provide correct passphrase can be
1227 overrided by the channel founder. Updated the protocol specs.
1228 Affected file silcd/command.c.
1230 Added support for founder auth in JOIN command in client
1231 library. Fixed the parsing of the JOIN command now to support
1232 all options as they should be. The affected file is
1233 lib/silcclient/command.c.
1235 * Optimized the WHOIS and IDENTIFY commands to send the request
1236 to router only if it includes nicknames or other names. If
1237 they include only IDs then check the local cache first before
1238 routing. Affected file is silcd/command.c.
1240 * Added channels topic announcements. Affected file is
1241 silcd/packet_receive.c and silcd/server.c.
1243 * Fixed the silc_server_send_notify_topic_set to really destine
1244 the packet to channel. Affected file silcd/packet_send.c.
1246 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1247 library. Affected file lib/silcclient/client_notify.c.
1249 * Added UMODE announcements. Affected file silcd/server.c.
1251 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Memory leak fixes in:
1255 lib/silcutil/silcsockconn.c
1256 lib/silcske/silcske.c
1257 lib/silcske/groups.c
1259 lib/silccrypt/silcpkcs.c
1260 lib/silccore/silccommand.c
1261 lib/silccore/silcidcache.c
1266 * ROBOdoc documented the lib/silcske/groups.h file and a
1267 bit changed the interface for better.
1269 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1271 * Update the client entry context in the ID cache after
1272 nick change. Affected file lib/silcclient/command.c.
1273 Fixes the CUMODE command when regaining founder privileges,
1274 and a little WHOIS problem.
1276 * Fixed silc_net_gethostbyname to correctly call the
1277 inet_ntop. Affected file lib/silcutil/silcnet.c.
1279 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1281 * Added IPv6 support checking to the configure.in.pre, added
1282 also --enable-ipv6 option to override the check. Affected
1283 file configure.in.pre.
1285 * The silc_thread_create now calls the start function
1286 directly if threads support is not compiled in. Removes
1287 ugly #ifdef's from generic code. Affected files are
1288 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1290 * Added silc_net_gethostby[name/addr]_async to asynchronously
1291 resolve. Affected files are lib/silcutil/silcnet.[ch].
1293 * Added support for rendering IPv6 based server, client and
1294 channel IDs. Affected file lib/silcutil/silcutil.c.
1296 * Added support for creating IPv6 based server IDs. Affected
1297 file is silcd/serverid.c.
1299 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1301 * Added silc_net_gethostby[addr/name] into the
1302 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1303 routines. Added silc_net_is_ip[4/6]. Affected file is
1304 lib/silcutil/unix/silcunixnet.c. All routines that take
1305 address as argument now supports both IPv4 and IPv6 addresses.
1307 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1309 * Fixed LIST command reply sending in server. Affected file
1312 * Server now sends the kicker's client ID in the KICK notify
1313 to the kicked client. Affected file silcd/command.c.
1315 * The client library now parses the kickers client ID and
1316 UI displays it. Affected files lib/silcclient/client_notify.c
1317 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1319 * Made all payload parsing function prototypes consistent.
1320 They all take now const unsigned char * and uint32 pair as
1321 the payload data instead of SilcBuffer. Changes all around
1322 the source tree. Other unsigned char* -> const unsigned char*
1323 changes around the tree as well.
1325 * Optimized SFTP client and server packet sending not to
1326 allocate new buffer for each packet but to recycle the
1327 first allocated buffer. Affected files are
1328 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1330 * Optimized the SFTP client to use SilcList instead of
1331 SilcDList for requests, because it is faster. Affected file
1332 is lib/silcsftp/sftp_client.c.
1334 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1335 into lib/silccore/silcid.[ch].
1337 Renamed silcpayload.[ch] into silcargument.[ch].
1339 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * If client entry is deleted with active key agreement
1342 session, abort the session.
1344 The silc_client_abort_key_agreement now calls the completion
1345 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1347 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1350 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Don't use __restrict in older GCC's. Affected file is
1353 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1355 * silc_net_localhost now attempts to reverse lookup the
1356 IP/hostname. Affected file lib/silcutil/silcnet.c.
1358 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1359 command. It can be used to gain founder privileges at
1360 the same time when joining the channel.
1362 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1363 kicker's client ID as well. Updated protocol specs.
1365 Defined that the server must send SILC_COMMAND_IDENTIFY
1366 command reply with error status to client who sent
1367 private message with invalid client ID.
1369 Updated the protocol specification.
1371 * Added silc_server_send_command_reply to send any
1372 command reply. Affected file silcd/packet_send.[ch].
1374 * Added silc_id_payload_encode_data to encode ID payload
1375 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1377 * The server now send IDENTIFY command reply with error
1378 status if client ID in private message is invalid. Affected
1379 file silcd/packet_receive.c.
1381 * Save the server key file with server's IP address in
1382 the filename instead of hostname. The affected file is
1383 irssi/src/silc/core/client_ops.c.
1385 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1390 * Added libtool support for compiling shared objects in
1391 lib/silcsim. Affected file configure.in.pre and
1392 lib/silcsim/Makefile.am. Original patch by cras.
1394 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Pid file configuration, and server's config file fixes
1397 patch by toma. Updated CREDITS file.
1399 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed silc_client_channel_message to not try to decrypt
1402 the message twice if it resolved the destination client
1403 information. This could cause of dropping one channel
1404 message. Affected file lib/silcclient/client_channel.c.
1406 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1409 lib/silcclient/client.c. This function is used when the SILC
1410 Client is run under some other scheduler, or event loop or
1411 main loop. On GUI applications, for example this may be
1412 desired to used to run the client under the GUI application's
1413 main loop. Typically the GUI application would register an
1414 idle task that calls this function multiple times in a second
1415 to quickly process the SILC specific data.
1417 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1419 * Fixed silc_server_drop() for dropping the supplementary
1420 groups as well, this could cause a security hole on some
1423 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1428 * Write PID file after dropping privileges. Added -F option
1429 to run server on foreground. A patch by debolaz.
1430 Affected files silcd/server.c, silcd/silcd.c.
1432 * Fixed MOTD to return the MOTD file server name. Affected
1433 file silcd/command.c.
1435 * Added INFO command reply handling to the Irssi SILC Client.
1436 Affected file irssi/src/silc/core/client_ops.c.
1438 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Fixed the silc_idcache_list_* routines to really support
1441 the dynamic list. Fixes a crash. Affected file is
1442 lib/silccore/silcidcache.c.
1444 * Fixed the LIST command reply to really call LIST command's
1445 pending callbacks. Affected file silcd/command_reply.c.
1447 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Update conn->local_entry->nickname after giving NICK
1450 command. Affected file lib/silcclient/command.c.
1452 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1454 * Added the [pid] option to the silcd configuration file
1456 Affected files: serverconfig.[ch] and silcd.c
1458 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Save fingerprint in WHOIS command reply in server.
1461 Affected file silcd/command_reply.c.
1463 * Fixed NICK commands pending callback registration.
1464 Affected file lib/silcclient/command.c.
1466 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Use ++server->cmd_ident when sending commands in server,
1469 instead of random number. Affected file silcd/command.c.
1471 * Fixed GETKEY command reply to call actually GETKEY pending
1472 command callbacks. Affected file silcd/command_reply.c.
1474 * A bit stricter check for nicknames. Check for same nickname
1475 in NICK command also. Affected file silcd/command.c.
1477 * Do not call INFO command everytime client ID changes, only
1478 during first connecting. Affected file lib/silcclient/client.c.
1480 * Set the new nickname only after successful command reply for
1481 NICK command is returned by server. Affected file
1482 lib/silcclient/command.c.
1484 * Remove nicknames from nicklist during server_signoff notify.
1485 Should fix /NAMES bit more. The affected file is
1486 irssi/src/silc/core/silc-channels.c.
1488 * Added `fingerprint' field to the SilcIDListData in the
1489 silcd/idlist.h to hold the fingerprint of the client's
1492 Send the fingerprint of the client's public key in WHOIS
1495 Affected files silcd/command.c, and silcd/idlist.[ch].
1497 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1498 create fingerprint from given data.
1500 * Show the fingerprint of the client's public key in WHOIS.
1501 Affected files irssi/src/module-formats.[ch] and
1502 irssi/src/silc/core/client_ops.c.
1504 * Format the multiple same nicknames also during JOIN and
1505 NICK_CHANGE notifys. Affected file is
1506 lib/silcclient/client_notify.c.
1508 * Do not print error on screen for invalid private message
1509 payload since it can come if someone is sending private
1510 messages with wrong key. Affected file
1511 lib/silccore/silcprivate.c.
1513 * Fixed multiple concurrent /PING crash. Affected file
1514 lib/silcclient/command.c.
1516 * Changed the wrong ID encoding. All IP addresses must be
1517 in MSB first order in encoded format. They were encoded
1518 wrong and was in LSB format. Affected files are
1519 silcd/serverid.c, lib/silcutil/silcutil.c.
1521 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1523 * Call the `connect' client operation through the scheduler
1524 in case of error. Affected file lib/silcclient/client.c.
1526 * Call the `failure' client operation even if the error
1527 occurred locally during a protocol. Affected file is
1528 lib/silcclient/protocol.c.
1530 * Added support of sending LIST command to router from normal
1531 server. This way normal server can get list of all channels
1532 in the network too. Fixed the channel list sending in the
1533 server too. Affected files are silcd/command.c, and
1534 silcd/command_reply.[ch].
1536 * Added silc_server_update_channels_by_server and
1537 silc_server_remove_channels_by_server. They are used during
1538 disconnection of primary router and in backup router protocol.
1539 Affected file silcd/server_util.[ch], silcd/server.c and
1540 silcd/server_backup.c.
1542 * Fixed channel adding to global list in IDENTIFY command
1543 reply in server. Affected file silcd/command_reply.c.
1545 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * If the incoming packet type is REKEY or REKEY_DONE process
1548 that packet always synchronously. Fixes yet another MAC
1549 failed error on slow (dialup) connections. Affected file
1550 lib/silcclient/client.c and silcd/server.c.
1552 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Call check_version SKE callback for initiator too. Affected
1555 file lib/silcske/silcske.c.
1557 * Implemented fix for security hole found in the SKE that was
1558 fixed in the specification few days back; the initiator's
1559 public key is now added to the HASH value computation.
1560 Added backwards support for the old way of doing it too, for
1561 old clients and old servers. Affected file is
1562 lib/silcske/silcske.c.
1564 * Enabled mutual authentication by default in SKE. If initiator
1565 is not providing mutual authentication the responder will
1566 force it. This will provide the proof of posession of the
1567 private key for responder. The affected files are
1568 lib/silcclient/protocol.c and silcd/protocol.c.
1570 * Do not cache anymore the server's public key during SKE.
1571 We do mutual authentication so the proof of posession of
1572 private key is done, and if the server is authenticated in
1573 conn auth protocol with public key we must have the public
1574 key already. Affected file silcd/protocol.c.
1576 * Added new global debug variable: silc_debug_hexdump. If
1577 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1578 file lib/silcutil/silclog.[ch].
1580 * Fixed compilation warning due to char * -> const char *.
1581 Affected files lib/silcutil/silcnet.h, and
1582 lib/silccore/silcauth.[ch].
1584 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Fixed CMODE command when new channel key was created. If
1587 the creation failed the old key was removed. Next time giving
1588 same command would crash the server since the old key was
1589 freed already. Affected file silcd/command.c.
1591 * Fixed the silc_server_announce_get_channels to not crash
1592 on reconnect. Affected file silcd/server.c.
1594 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1596 * Added silc_log_set_debug_string function to set a regex
1597 string to match for debug output. Only the function names,
1598 or filenames matching the given debug string is actually
1599 printed. This way it is possible to filter out those debug
1600 strings that user is not interested in.
1602 Fixed a bug in silc_string_regexify.
1604 Affected files lib/silcutil/silclog.[ch], and
1605 lib/silcutil/unix/silcunixutil.c.
1607 * Changed the -d options in both server and Irssi SILC client
1608 to take the debug string as argument. Affected files
1609 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1611 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * Added silc_hash_babbleprint to create a Bubble Babble
1614 Encoded fingerprint. The encoding is developed by Antti
1615 Huima (draft-huima-babble-01.txt), and it creates human
1616 readable strings out of binary data. Affected file
1617 lib/silccrypt/silchash.[ch].
1619 * Print the babble print now in addition of fingerprint as well
1620 in Irssi SILC client. Affected files are
1621 irssi/src/fe-common/silc/module-formats.[ch],

1624 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Fixed a security problem found in SKE. The initiator's
1627 public key too is now added to the HASH hash value creation
1628 which is signed by the responder to create the SIGN value.
1629 This will prevent anyone in the middle to lie to the responder
1630 about the initiator's public key. If this is done now, the
1631 man in the middle will get caught. Updated the protocol
1634 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1636 * Better installation directory handling. Configure module
1637 paths and other paths automatically to example_silc* files
1638 in doc/. A patch by toma.
1640 * Fixed compiler warning from MPI library, and from SILC RNG.
1643 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1644 It can be configured with ./configure. A patch by toma.
1646 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1648 * Find correct make to use in prepare-clean. A patch by
1649 toma. Affected file prepare-clean.

1668 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Added silc_pkcs_public_key_compare to compare two
1671 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1673 * Check that the client who set the founder mode on the
1674 channel is the same client that is giving the founder
1675 mode to itself. It is done by comparing the saved public
1676 key (it is saved even in the authentication is passphrase).

1684 * Process the DISCONNECT packet through scheduler in the
1685 client library. Affected file lib/silcclient/client.c.
1687 * Fixed the silc_client_packet_parse to not to increase
1688 the packet sequence number if the conn->sock and the
1689 current socket connection is not same. This can happen
1690 for example during key agreement when the conn includes
1691 multiple socket connections (listeners). Affected file
1692 lib/silcclient/client.c.
1694 * The sender of the file transfer request now provides also
1695 the pointer (listener) for the key exchange protocol. If
1696 the listener cannot be created then it sends empty key
1697 agreement and lets the receiver provide the listener.
1699 Added `local_ip' and `local_port' arguments to the
1700 silc_client_file_send. If they are provided they are used,
1701 if not then it will attempt to find local IP address, if
1702 not found or bind fails then the remote client will provide
1705 Affected files are lib/silcclient/client_ftp.c and
1706 lib/silcclient/silcapi.h.
1708 * Extended the FILE SEND command to support defining the
1709 local IP and port for key exchange listener. They are

1714 * Defined to WHOIS command reply the sending of fingerprint
1715 of the client's public key (if the proof of posession of the
1716 corresponding private key is verified by the server).
1717 Updated to the protocol specification.
1719 * Added support of receiving the client's public key's
1720 fingerprint in command reply in client library. Affected
1721 file is lib/silcclient/command_reply.c, and
1722 lib/silcclient/idlist.[ch].
1724 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1781 preserve the WHOWAS info for the client. Affected file
1782 silcd/server_util.c.
1784 * Fixed SERVER_SIGNOFF notify handling in the server. The
1785 server is now able to process incoming SERVER_SIGNOFF notify
1786 for a server that it doesn't even know about. It will remove
1787 the clients provided in the notify. Affected file
1788 silcd/packet_receive.c.
1790 * Check for partial packet in data queue after every packet that
1791 was found from the queue. Return and wait for more data if
1792 there is partial data in queue. Affected file is
1793 lib/silccore/silcpacket.c.
1795 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1810 irssi/src/fe-common/silc/module-formats.[ch].
1812 * Wrote a help file for FILE command.
1814 * Added silc_rng_global_get_byte_fast to get not-so-secure
1815 random data as fast as possible. Random data is read from
1816 /dev/urandom if available and from the SILC RNG if not
1817 available. It is used in padding generation. Affected file
1818 lib/silccrypt/silcrng.[ch].
1820 * All packets in client library are now processed synchronously.
1821 Optimized packet processing a lot. Affected file
1822 lib/silcclient/client.c.
1824 * All server connection packets are processing synchronously
1825 now in server, to optimize packet processing. Affected file
1828 * Include files are installed now only in Toolkit distribution
1829 if make install is given. Affected files: all Makefile.am's.
1831 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Assure that silc_client_notify_by_server_resolve does not
1834 resolve the client information multiple times. If it cannot
1835 be found by the first it cannot be found at all. Affected
1836 file lib/silcclient/client_notify.c.
1838 * Fixed WHOWAS command reply calling. Affected file
1839 lib/silcclient/command_reply.c.
1841 * Removed all references to silc_idlist_get_client from the
1842 Irssi SILC client since that call is internal call used by
1843 the library. The Irssi SILC client will use now client
1844 retrieval functions found in silcapi.h.
1846 * Fixed a bug in resolving nickname info before sending
1847 private message. It used freed memory. Affected file
1848 irssi/src/silc/core/silc-servers.c.

1869 * Added silc_net_localip to return local host's IP address.
1870 Affected file lib/silcutil/silcnet.[ch].
1872 * If key exchange or rekey protocol is active for a connection
1873 parse all packets syncronously since there might be packets
1874 in packet queue that we are not able to process without first
1875 processing packets before them. Affected file silcd/server,
1876 lib/silcclient/client.c.
1878 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1879 whether library should continue processing the packet.
1880 Affected file lib/silccore/silcpacket.h.

1926 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1927 is incomplete and is being resolved, it won't be resolved
1930 Make sure also that USERS command reply does not resolve
1931 twice information. Affected file is
1932 lib/silcclient/command_reply.c.
1934 Make sure that silc_client_get_clients_by_list does not
1935 resolve twice same information.
1937 * Check for valid client->id in the silc_server_free_client_data.
1938 Affected file silcd/server.c.
1940 * Fixed /GETKEY nick@server not to crash if the server entry
1941 is not found. Affected file lib/silcclient/command.c.

1953 * Call the silc_server_udpate_servers_by_server in the
1954 primary router that comes back online in the backup resuming
1955 protocol. Otherwise it routes packets wrong. Affected file
1956 silcd/server_util.[ch], silcd/server_backup.c.
1958 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1960 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1961 lib/silcutil/silcbuffmt.[ch].
1963 * Redefined the SILC packet header to include the padding
1964 length. Affected file lib/silccore/silcpacket.[ch].
1966 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1967 length for maximum padding up to 128 bytes). Affected
1968 file lib/silccore/silcpacket.h.
1970 * Removed all backwards support for old 0.5.x MAC thingies.
1971 The SILC packet header change makes it impossible to be
1972 backwards compatible.
1974 * Send the ENDING packet with timeout in the backup resuming
1975 protocol. This is to assure that all routers has connected
1976 to the primary router. Affected file silcd/server_backup.c.
1978 * Changed the RNG to take the first IV from random data. It
1979 used to take it from zero actually. Changed the RNG also
1980 to use /dev/urandom during session. /dev/random is used
1981 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1983 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Changed the SILC packet header to have the first two bytes
1986 (the packet length) encrypted. Affected files aroung the
1987 code tree, lib/silccore/silcpacket.[ch]. Removed the
1988 SilcPacketCheckDecrypt callback. It is not needed anymore
1989 since the silc_packet_receive_process will determine now
1990 whether the packet is normal or special.
1992 * Implemented the unidirectional MAC keys. Affected files
1993 lib/silcske/silcske.c, silcd/protocol.c and

2001 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Allow backup router to announce servers. All servers
2004 announced by backup router are added to the global list
2005 automatically. Update hte server's socket to our primary
2006 router also when backup router announces a server.
2007 Affected file silcd/packet_receive.c.
2009 * Do not update the client->router in the function
2010 silc_server_udpate_clients_by_server if the client is on
2011 global list. We might fail to find any specific server
2012 for locally connected clients and local cell clients. They
2013 should still use the `from' and not `to' as client->router.
2014 This fixes backup router resuming protocol. Affected file
2015 silcd/server_util.c.
2017 * Decrease channel statistics count only if the channel
2018 deletion worked. Affected files are silcd/server.c and
2019 silcd/server_util.c.
2021 * Added silc_server_update_servers_by_server to update origin
2022 of all server entries. Used during backup router protocol.

2031 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Assure that router cannot reroute the same channel message
2034 to the sender. Affected file silcd/packet_receive.c.
2036 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Made better checks that the channel message is not sent
2039 to the router it came from. Affected file is
2040 silcd/packet_send.c. Fixed memory leak too.
2042 * Announce informations for incoming router connection, but
2043 only after checking if it is replaced by backup router.
2044 Affected file silcd/packet_receive.c.
2046 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Fixed the backup resuming protocol to work in multiple
2049 router environment. Affected file silcd/server_backup.c.
2051 * Route packet only to one router in the function
2052 silc_server_packet_send_to_channel. Affected file is
2053 silcd/packet_send.c.
2055 * Fixed silc_server_send_notify_dest to set the broadcast
2056 flag. Fixed the silc_server_send_notify_topic to actually
2057 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2058 Affected file silcd/packet_send.c.
2060 * Changed the SFTP Filesystem interface. Changed the
2061 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2062 the filesystem operation function. The SilcSFTPFilesystem
2063 is now a context that is allocated by all filesystem allocation
2064 functions and it already includes the operations structure
2065 and filesystem specific context. It is given as argument
2066 now to the silc_sftp_server_start. This made the interface
2067 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2068 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2070 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Changed the backup router adding and getting interfaces
2073 in the server. The router that will be replaced by the
2074 specified backup router is now sent as argument. Affected
2075 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2078 * Added silc_net_addr2bin_ne to return the binary form of
2079 the IP address in network byte order. Affected files

2082 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Check for existing server ID in silc_server_new_server
2085 and in silc_server_connect_to_router_final and remove the
2086 old entry if it exists. Affected file silcd/packet_receive.c,
2089 * Send the channel message always to only one router, either
2090 in upstream or downstream. Affected file is
2091 silcd/packet_send.c.
2093 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Wrote the definition of the backup resuming protocol to the
2096 protocol specification.
2098 * Removed one redundant channel key generation from normal
2099 server during joining procedure. Removed one redundant
2100 channel key sending from server to router during joining
2101 procedure. Affected file silcd/command.c.
2103 * Made minor bugfixes to the backup router resuming protocol.
2104 Affected file silcd/server_backup.c, server.c.

2113 resume the primary router position in the cell after the
2114 primary router comes back online. Affected files
2115 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2116 and silcd/server_util.[ch].
2118 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Sleep two (2) seconds after sending QUIT command to server.
2121 Affected file lib/silcclient/command.c.
2123 * Assure that if outgoing data buffer is pending do not force
2124 send any data. Affected file silcd/packet_send.c.
2126 * Assure that if outgoing data buffer is pending do not force
2127 send any data. Affected file lib/silcclient/client.c.
2129 * Implemented the backup router support when the primary router
2130 goes down. The servers and routers can now use the backup
2131 router as new primary router without loosing connectivity.
2133 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2135 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2136 in the server to indicate disabled entry. All data read
2137 from the connection will be ignored and no data is sent
2138 for entry that is disabled. Affected files are
2139 silcd/idlist.h, silcd/server.c.
2141 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Created SFTP client and server test programs in the
2144 lib/silcsftp/tests directory.
2146 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Implemented memory filesystem (virtual filesystem) for
2149 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2152 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Implemented the SFTP (SSH File Transfer Protocol) to the
2155 lib/silcsftp. It includes SFTP client and SFTP server
2158 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Moved lib/silccore/silcprotocol.[ch] to the
2161 lib/silcutil library.
2163 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2164 take variable argument list pointer as argument. Affected
2165 file lib/silcutil/silcbuffmt.[ch].
2167 * Added silc_buffer_set function that is used to set data
2168 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2169 Affected file lib/silcutil/silcbuffer.h.
2171 * Changed various routines in the core library to use the new
2172 silc_buffer_set instead of allocating new buffer only for
2175 * Added 64-bit value formatting and unformatting support to the
2176 silc_buffer_[un]format routines. Affected file is
2177 lib/silcutil/silcbuffmt.[ch].
2179 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2180 to includes/bitmove.h.
2182 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Fixed channel user mode saving in client library. Affected
2185 file lib/silcclient/command[_reply].c.
2187 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Defined the file transfer to the SILC Protocol. Added
2190 new packet type SILC_PACKET_FTP and defined File Transfer
2191 Payload. The mandatory file transfer protocol is SFTP
2192 (SSH File Transfer Protocol). Affected file in addition
2193 of the internet draft is lib/silccore/silcpacket.h.
2195 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2196 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2197 is used as part of backup router protocol when the primary
2198 router of the cell is back online and wishes to resume
2199 the position as primary router.
2201 * Redefined the MAC generation keys in the protocol. The
2202 same key is not used anymore in both direction. Both
2203 direction will now use different keys for sending and
2204 receiving. This fixes a potential security flaw. This
2205 change causes incompatibilities in the protocol.
2207 * Redefined also the MAC computation from the packet.
2208 An packet sequence number is now added to the MAC
2209 computation. This prevents possible replay attacks against
2210 the protocol. This change too causes incompatibilities
2213 Added `sequence' field to the SilcPacketContext to hold
2214 the current sequence number for the packet.
2216 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2218 * Added `created' field to the SilcIDListData in the file
2219 silcd/idlist.h to indicate the time when the entry was
2222 * Added `created' field to the SilcChannelEntry too. Affected
2223 file silcd/idlist.h.
2225 * Added `creation_time' aguments to all the announcement functions
2226 in the server. If it is provided then only the entries that
2227 was created after the provided time frame are actually
2228 announced. Affected file silcd/server.[ch].
2230 * The protocol says that the Channel ID's IP address must be
2231 based on the router's IP address. Added check for this in
2232 the silc_server_new_channel when processing incoming New Channel
2233 Payload. Affected file silcd/packet_receive.c.
2235 * Print out the correct version with --version in SILC client.
2236 Affected file irssi/src/silc/core/silc-core.c.
2238 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Fixed WHOWAS command to check for completnes of the client
2241 entry always, not just when the command is coming from client.
2242 Affected file silcd/command.c.
2244 * Added new function silc_server_packet_queue_purge to purge the
2245 outgoing data queue to the network. After the function returns
2246 it is guaranteed that the outgoing packet queue is empty.
2247 Affected file silcd/packet_send.[ch].
2249 * Purge the outgoing packet queue in the rekey protocol's final
2250 callback to assure that all rekey packets go to the network
2251 before quitting the protocol. Affected file silcd/server.c.
2253 * Added silc_client_packet_queue_parse as similar function as
2254 in server to the client library. The affected file is
2255 lib/silcclient/client.c.
2257 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Splitted silcd/server.c and created silcd/server_util.[ch]
2260 for utility functions.
2262 * Added new socket flag SILC_SF_DISABLED to indicate that the
2263 connection is open but nothing can be sent to or received from
2264 the connection. Affected file lib/silcutil/silsockconn.[ch].
2265 The checking for disabled socket is checked in the low level
2266 silc_socket_write and silc_socket_read functions.
2268 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2270 * Allow only nicknames and channel names that fits into the
2271 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2273 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2275 * When processing JOIN command reply in server check that if
2276 the channel exists in our global list we'll move it the local
2277 list. Affected file silcd/command_reply.c.
2279 * Fixed the check whether client is joined on the channel already
2280 in JOIN command. Affected file lib/silcclient/command.c.
2282 * Fixed the JOIN command reply to check whether the channel
2283 already exists. Affected file lib/silcclient/command_reply.c.
2285 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Added silc_ske_status_string to map the SKE error numbers
2288 to readable strings. The affected files are
2289 lib/silcske/silcske[_status].[ch].
2291 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2293 * Do not show the private channels on the WHOIS channel list
2294 as it is not allowed by the protocol. The affected file is
2297 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2299 * Assure that the packet length digged from the actual packet
2300 is something sensible in the silc_packet_decrypt_rest_special
2301 in lib/silccrypt/silcpacket.c.
2303 * Free and NULL the allocated pointer in silc_hmac_alloc if
2304 the HMAC allocation fails. The affected file is
2305 lib/silccrypt/silchmac.c.
2307 * Print the selected security properties to the log files in
2308 the server. Affected file silcd/protocol.c.
2310 * Add SKE's reference counter even if calling the completion
2311 callback manually. Otherwise it goes negative, although it
2312 does not cause any problems. The affected file is
2313 lib/silcske/silcske.c.
2315 * Remove the client entry with short timeout after giving the
2316 KILL command. Affected file lib/silcclient/command.c.
2318 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2319 case all found clients are already disconnected (WHOWAS would
2320 found them) in the server. Affected file silcd/command.c.
2322 * Update the last_receive (time of last data received) to be
2323 updated only when received private or channel message so that
2324 the idle time showed in WHOIS makes more sense.
2326 * Added boolean field `valid' in to the SilcClientEntry in the
2327 client library to indicate whether the entry is valid or not.
2328 This fixes the nickname change bug on channel when changing
2329 the nickname to be same than the old (like nick to Nick) the
2330 nickname formatter doesn't set the new nick anymore to Nick@host.
2331 Affected file lib/silcclient/idlist.[ch].
2333 * Now actually fixed the nickname changing on disconnection.
2334 Added new function silc_change_nick to the Irssi SILC Client.
2335 Affected file irssi/src/silc/core/client_ops.c,
2336 irssi/src/silc/core/silc-nicklist.[ch].
2338 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Check that the public key exists in the GETKEY command before
2341 trying to encode it. Affected file silcd/command.c.
2343 * Print some notifications on received public keys with GETKEY
2344 command in the Irssi SILC Client. Affected files are
2345 irssi/src/fe-common/silc/module-formats.[ch],
2346 irssi/src/silc/core/client_ops.c.
2348 * Use IDENTIFY command to resolve the server information in the
2349 GETKEY command instead of INFO command. Affected file
2350 lib/silcclient/command.c.
2352 * All command reply functions in the client library now calls
2353 the pending command reply callbacks even if an error has
2354 occurred. The server has done this a long time and now it was
2355 time to move the client library to this as well. Now all
2356 errors can be delivered back to the pending command reply
2357 callbacks if necessary. Affected files are
2358 lib/silcclient/command[_reply].[ch].
2360 * Change the nickname on disconnection back to the username
2361 because in reconnect the server will enforce it to it anyway.
2362 Affected file irssi/src/silc/core/silc-servers.c.
2364 * Fixed a config file parsing bug in the Irssi SILC client.
2365 Affected file irssi/src/silc/core/clientconfig.c.
2367 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * When printing the channel mode on JOIN, verify that the
2370 channel key and channel's HMAC are valid. Affected file
2371 irssi/src/silc/core/client_ops.c.
2373 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2376 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2377 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2379 * Removed channel key rekey task deleting from the function
2380 silc_server_save_channel_key. Affected file silcd/server.c.
2381 Added explicit timeout task context instead that is used to
2382 delete the task if we are registering a new task before the
2383 new task has elapsed.
2385 * When channel key rekey occurs the client library now saves
2386 the old channel key for a short period of time (10 seconds) and
2387 is able to use it in case some is still sending channel
2388 messages encrypted with the old key after the rekey. Affected
2389 file lib/silcclient/[idlist.h|client_channel.c].
2391 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Added check to the silc_server_new_id_real to not accept
2394 new ID if it is the sender's own ID. Affected file is
2395 silcd/packet_receive.c.
2397 * Assure that we do not announce ourself or the one we've
2398 sending our announcements when we're router and are announcing
2399 servers to our primary router. Affected file silcd/server.c.
2401 * Fixed silc_server_command_identify_check_client to assemble
2402 correct WHOIS packet. It send corrupted WHOIS packet and
2403 caused problem with router to router connections. Affected
2404 file silcd/command.c.
2406 Fixed also silc_server_command_whois_check the same way
2407 as for the IDENTIFY command.
2409 * Added new SilcIDListStatus to the server in the SilcIDListData
2410 structure. The status now includes the current status of
2411 the entry (like registered, resolved etc.). Affected file
2412 silcd/idlist.[ch]. Defined a bunch of different status types
2413 as well. This replaced the old boolean registered field as well.
2415 Added resolve_cmd_ident field to the SilcClientEntry structure
2416 too so that if the entry is for example being resolved so
2417 another command may attach to the same pending command reply
2418 without requiring to resolve the same entry again. This concept
2419 should optimize the WHOIS and the IDENTIFY resolving under
2420 heavy load by taking away unnecessary resolving for entries
2421 that are being resolved already.
2423 Added support for adding multiple pending commands for one
2424 command idenfier. Affected file silcd/command[_reply].[ch].
2426 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2427 before deleting the data. Otherwise the hash table will have
2428 freed data in comparison functions. Affected file is
2429 silcd/command_reply.c.
2431 * Fixed silc_idlist_replace_client_id to add the new entry to
2432 the cache with NULL nickname. Otherwise there will be invalid
2433 memory as the nickname after the nickname is freed. Affected
2434 file silcd/packet_receive.c.
2436 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2437 saved into wrong slots because the previous number of entries
2438 was not taken into account. Affected file silcd/idlist.c.
2439 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2441 * If we are router and we receive JOIN notify to a channel that
2442 does not have any users then notified client is marked as the
2443 channel founder, as it is it. The affected file is
2444 silcd/packet_receive.c
2446 * Added to the extended hash table API's table_del_*ext functions
2447 the destructor as argument too, so that the caller can decide
2448 which destructor to use or whether to use destructor at all.
2449 Affected file lib/silcutil/silchashtable.[ch].
2451 * Fixed ID Cache purging. It actually deleted the entries from
2452 the hash table after the data was freed. The hash table ended
2453 up comparing freed memory. The affected file is
2454 lib/silccore/silcidcache.c.
2456 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Fixed Irssi SILC client's KILL command's HELP syntax.
2460 * The USERS command now resolves the detailed user information
2461 if the userinfo field is missing. Affected file is
2462 lib/silcclient/command_reply.c.
2464 * Do not print error in silc_file_read if the read file does
2465 not exist. Just silently return NULL. Affected file is
2466 lib/silcutil/silcutil.c.
2468 * Fixed the silc_log_output to not wine about NULL filename
2469 and to not create some bogus " " filename. Affected file is
2470 lib/silcutil/silclog.c.
2472 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Fixed various printing bugs on the user interface in the
2475 Irssi SILC Client. Minor changes that were forgotten from
2478 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Fixed the configure.in.pre and the compilation and distribution
2481 environment to support the new autoconf 2.52. That version is
2482 now required to compile the CVS trunk.
2484 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2487 to generally parse user@fqdn format strings. Affected file
2488 lib/silcutil/silcutil.c.
2490 * Added nickname_format and nickname_force_format fields to the
2491 SilcClientParams structure. The first one defines the format
2492 for the nicknames that the library will enforce if the receives
2493 multiple same nicknames. The second one is boolean value and
2494 can be used to force the library to always enforce the format
2495 to the nicknames regardles whether there are multiple nicknames
2496 or not. This configurable formatting was employed to flexibly
2497 support accessing multiple nicknames from the user interface.
2498 The userinterface can now set the nicknames to what ever format
2499 they prefer. Affected file lib/silcclient/silcapi.h.
2501 Added function silc_client_nickname_format to the file
2502 lib/silcclient/idlist.c. It performs the nickname formatting.
2504 Added new field `hostname´ to the SilcClientEntry context.
2505 It holds the hostname of the client. Affected file is
2506 lib/silcclient/idlist.h.
2508 * Irssi SILC Client sets the nicknames in nick@hostn format.
2509 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2510 irssi/src/silc/core/silc-core.c.
2512 The WHOIS printing now also shows both the real nickname and
2513 the formatted nickname so that user knows how to access the
2514 user if there are multiple same nicknames cached. Affected
2515 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2516 printing formatting too to take the hostname now as a separate
2517 argument. The Affected file is
2518 irssi/src/fe-common/silc/modules-formats.[ch].
2520 * Changed the silc_client_get_clients_local to accept the formatted
2521 nickname as argument. It accepts the real nickname too but the
2522 formatted nickname can be used to find the true entry from
2523 multiple entries. Affected file lib/silcclient/silcapi.h and
2524 lib/silcclient/idlist.c.
2526 * Added nickname_format_parse field to the SilcClientParams.
2527 It is a callback function provided by the application to parse
2528 the nickname out of the formatted nickname string. The library
2529 calls it to get the nickname from the formatted string. Since
2530 the application generally knows better the format of the nickname
2531 string it parses it instead of the library, even though library
2532 encodes the formatted string. If the callback function is not
2533 provided then the library will use the string as is. The
2534 affected file is lib/silcclient/silcapi.h.
2536 * All the nickname strings passed to the client library in
2537 commands are now expected to be formatted nickname strings.
2538 If the command does not support the formatted nickname string
2539 it will assume that the sent string is the actual nickname.
2540 Affected file lib/silcclient/command.c.
2542 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Added public key authentication support to OPER and SILCOPER
2545 commands in the client library. Affected file is
2546 lib/silcclient/command.c.
2548 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Changed the get_auth_methdod client operation to be asynchronous.
2551 It can be async if the application resolves the authentication
2552 method from the server during the negotiation. Added new
2553 SilcGetAuthMeth completion callback that the application will
2554 call after resolving the authentication method.
2556 Added function silc_client_request_authentication_method that
2557 the application can use to resolve the authentication method
2558 from the server. Added also SilcConnectionAuthRequest callback
2559 that the library will call after the server has replied. The
2560 application can call this function if it does not know the
2561 current authentication method.
2563 Affected files are lib/silcclient/client.c and
2564 lib/silcclient/silcapi.h.
2566 * The Irssi SILC client now automatically resolves the authentication
2567 method incase any configuration information is not present (and
2568 currently there never is). The affected file is
2569 irssi/src/silc/core/client_ops.c.
2571 * Fixed public key authentication from the client library.
2572 Affected file lib/silcclient/protocol.c. Changed also the
2573 protocol specification about the public key authentication in
2574 the connection authentication protocol. The actual data to be
2575 signed is now computed with a hash function before signing.
2577 * Fixed the public key authentication from the server as well.
2578 Affected file silcd/protocol.c.
2580 * Removed the mlock()'s from the memory allocation routines.
2581 Affected file lib/silcutil/silcmemory.c. The ./configure does
2582 not check anymore for the mlock(). Affected file is
2585 * Fixed USERS command in server to allow the execution of the
2586 command for private and secret channels if the client sending
2587 the command is on the channel. Affected file silcd/command.c.
2589 * Fixed silc_client_get_clients_local to return the clients
2590 count correctly. It could return wrong value. Affected file
2591 lib/silcclient/idlist.c.
2593 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2596 types. The assembler optimizations seemed not to like 64-bit
2597 data types. The assmebler optimizations thus are now enabled
2598 also for BSD systems as opposed to only enable them for Linux.
2600 * Do not check for threads at all on BSD systems. Affected
2601 file configure.in.pre.
2603 * Removed -n and -h options from the Irssi SILC Client since
2604 they are not used in silc.
2606 * Fixed the prime generation to assure that the first digit
2607 of the generated random number is not zero since our conversion
2608 routines does not like number strings that starts with zero
2609 digit. If zero digit is seen the random number is regenerated.
2610 This caused some corrupted RSA keys when the zero first digit
2611 was met. Affected file lib/silcmath/silcprimegen.c.
2613 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Fixed WIN32 configuration in the ./configure script.
2616 Fixed to include xti.h on environments that has it.
2617 Patches by Carsten Ilchmann and andrew.
2619 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Changed the silc_id_create_client_id to be collision
2622 resistant. It is now assured that there cannot be created
2623 two same client ID's. I suspect that some weird bugs in
2624 the server were actually caused by duplicate Client IDs.
2625 Affected file silcd/serverid.[ch]. A router receiving
2626 new ID now also assures and informs the sending server
2627 if the ID caused collision.
2629 * Changed the silc_id_create_channel_id to also assure that
2630 there are no collisions.
2632 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Statement about ignoring the Mutual Authentication flag when
2635 performing rekey with PFS was a bit misleading. It is ignored
2636 if it was set in the initial negotiation, it cannot be even
2637 set in the rekey. Fixed in the ke-auth draft. Started the
2638 new versions of the protocol drafts in the doc/.
2640 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Fixed a bug in silc_client_command_identify_save when saving
2643 new channel information. The channel name was no duplicated
2644 and caused crash on exit. Affected file is
2645 lib/silcclient/command_reply.c.
2647 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2649 * Fixed the getkey command handling in the server. Send just
2650 empty OK reply to the sender if the key could not be fetched
2651 (but everything else was ok, like the key just was not available).
2652 Changed the public key parameter to optional in the protocol
2653 specs so that empty OK reply can be sent. Affected file
2656 Added a message to Irssi SILC client to tell to user if the
2657 server did not return a public key.
2659 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Fixed a channel key regeneration bug. It registered new
2662 timeout tasks exponentially until all system resources were
2663 used. Affected file silcd/server.c.
2665 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Added the SILC Document generator to the scripts/silcdoc.
2668 It can be used to generate the Toolkit Reference Manual out
2669 of the source tree. Internally it will also use the RoboDoc
2670 generator now imported in util/robodoc.
2672 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Added couple of return's in rekey protocol if error orccurred
2675 during the protocol. The execution must be terminated.
2676 Affected file silcd/protocol.c. Also, terminate the protocol
2677 always with timeout.
2679 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2681 * The client's Client ID was created initally from the wrong
2682 nickname (it could have been in format nick@host) in the
2683 silc_server_new_client. Affected file silcd/packet_receive.c
2685 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Added some SILC_LOG_ERROR's to various error conditions
2688 if client could not be added to ID cache. Affected files
2689 silcd/packet_receive.c and silcd/server.c.
2691 * When client's sock->user_data is freed, NULL also the
2692 client->router and client->connection pointers. Added check
2693 for these pointers being NULL to various places around the
2694 code. Affected file silcd/server.c.
2696 * Added client->data.registered == TRUE checks to various
2697 places around the code to assure that unregistered client's
2698 are not handled when it is not allowed. Affected file
2701 * Added `bool registered' fields to all
2702 silc_idlist_[server|client]_get_* routines to indicate whether
2703 the fetched client needs to be registered or not. Affected
2704 file silcd/idlist.[ch].
2706 * Add your own entry as registered to the ID cache in the
2707 server. Affected file server.c.
2709 * Fixed a bug in silc_server_new_server. The SilcServer was
2710 set as the new server's context instead of SilcServerEntry.
2711 This naturally caused some weird bugs.
2713 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2715 * Do not delete the channel rekey task when adding it
2716 for in silc_server_create_channel_key.
2718 * Changed the silc_server_create_channel_key to return
2719 TRUE or FALSE to indicate the success of the channel key
2722 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2724 * Fixed MSVC++ project files and added missing files to

2727 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Do not add TCP_NODELAY flag if the operating system
2730 does not have it defined. Affected files are
2731 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2733 * Fixed buffer overflow from Irssi SILC Client. Affected
2734 file irssi/src/fe-common/core/themes.c.
2736 * Fixed double free in client library in the file
2737 lib/silcclient/client.c when disconnecting from server.
2739 * Applied double free patch from cras to Irssi SILC client.
2740 Affected files irssi/src/core/[modules/expandos].c
2742 * Fixed the disconnection handling to Irssi SILC Client.
2743 The application must call silc_client_close_connection
2744 in ops->connect client operation in case of failure of
2745 the connection. Affected file is
2746 irssi/src/silc/core/client_ops.c.
2748 * Do not set sock->protocol to NULL in the function
2749 silc_client_close_connection after executing the protocol's
2750 final callback since the sock might not be valid anymore.
2751 Affected file lib/silcclient/client.c.
2753 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Do not enable SILC_THREADS if the linking with libpthread
2756 did not happen. Affected file configure.in.pre.
2758 * Added notion to protocol specification that server must
2759 verify the sent authentication payload with CMODE when
2760 setting the channel founder key. Implemented it to the
2761 server. Affected file silcd/command.c.
2763 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Added _EXTRA_DIST SILC distribution variable to the
2766 distributions file. It is used to conditionally add extra
2767 files or directories to the specific distribution. Affected
2768 files ./prepare, Makefile.am.pre and distributions.
2770 Removed the `_' from the start of the distribution names.
2773 * Added README.WIN32 for instructions to compile the Toolkit
2776 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Fixed a double free in disconnection in the server. Affected
2779 file is silcd/server.c.
2781 * Fixed the lib/silcske/groups.c to work now also with GMP
2782 MP library. The string conversion did not work when using
2783 specific base and the base is indicated in the string as well.
2785 * Created win32/ directory which now includes MSVC++ specific
2786 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2787 It will appear only in the toolkit distribution
2789 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Changed the key material distribution function in case when
2792 the hash output is too short. The data is now concatenated
2793 a bit differently than it used to. Made the change to the
2794 SKE protocol specification.
2796 * Added better GMP detection to configure.in.pre. A patch
2799 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * Fixed a minor bug in SKE that might cause some problem on
2802 some platforms. Affected file lib/silcske/silcske.c.
2804 * Added the cookie checking for initiator in the SKE. It checks
2805 that the responder returns the sent cookie unmodified. The
2806 affected file is lib/silcske/silcske.c. Added new SKE
2807 error type INVALID_COOKIE that can be sent during the
2808 negotiation. Fixed some memory leaks as well.
2810 * Added the "invalid cookie" error message to Irssi SILC client's
2813 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2815 * Added `task_max' field to the SilcClientParams to indicate
2816 the maximum tasks the scheduler can handle. If set to zero,
2817 default values are used. Affected file lib/silcclient/silcapi.h.
2819 * Fixed memory leaks in silc_client_close_connection. Affected
2820 file lib/silcclient/client.c.
2822 * Added silc_client_del_client_entry to client library to free
2823 all memory of given client entry. Affected file is
2824 lib/silcclient/idlist.[ch].
2826 * Added new functions silc_client_del_channel and
2827 silc_client_del_server to delete channel and server entries.
2828 Affected file lib/silcclient/[silcapi.h/idlist.c].
2830 * Removed silc_client_del_client_by_id from silcapi.h.
2832 * Fixed the INFO command to return the server's own info
2833 correctly when querying by Server ID. Affected file is
2836 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2838 * Removed the non-blocking settings in WIN32 code in the
2839 silc_sock_[read/write] and added SleepEx instead. Affected
2840 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2841 of input data is now checked with FIONREAD and ioctlsocket.
2843 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Call silc_schedule_task_del_by_context in the
2846 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2847 Affected file lib/silccore/silcprotocol.c.
2849 * Call silc_protocol_cancel for active protocols in the
2850 silc_server_close_connection if the funtion
2851 silc_server_free_sock_user_data has not been called.
2852 Affected file silcd/server.c.
2854 * Generic tasks cannot be deleted using the del_by_fd
2855 task deleting function since generic tasks does not match
2856 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2858 * Added a notion to SILCOPER help file that the SILCOPER works
2859 only on router server, not on normal server.
2861 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Added for WIN32 support for the new scheduler as well.
2864 Affected file lib/silcutil/win32/silcwin32schedule.c.
2866 * Fixed the SHA1 implementation to work on various platforms.
2868 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2871 API. It is part of the scheduler now. Everything else is
2872 as previously but some functions has changed their names.
2873 Checkout the lib/silcutil/silcschedule.h for the interface.
2874 Updated all applications to use the new interface. Affected
2875 files are lib/silcutil/silcschedule.[ch].
2877 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Found a bug in the SKE implementation. The HASH value,
2880 specified by the protocol, was not computed correctly. The
2881 public key of the responder was not added to the computation
2882 even though it is mandatory. Affected file lib/silcske/silcske.c.
2883 This unfortunately causes incompatibilities with older
2884 clients and servers.
2886 * Added WIN32 specific network init and uninit functions:
2887 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2888 the Winsock2. Affected file lib/silcutil/silcnet.h and
2889 lib/silcutil/win32/silcwin32net.c.
2891 * Set the socket always to nonblocking mode on WIN32 after
2892 reading data or writing data. Affected file is
2893 lib/silcutil/win32/silcwin32sockconn.c.
2895 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Fixed various compilation problems under WIN32. Affected
2898 files lib/silcutil/win32/silcwin32thread.c and
2899 lib/silcutil/win32/silcwin32schedule.c.
2901 * Removed all _internal.h #includes from public header
2902 files. Internal headers must never be included from
2905 Removed also the lib/silcske/payload_internal.h file.
2907 * All include files that may be needed (public and some others
2908 included by the public headers) by application developers are
2909 now copied to the ./includes directory. It does not copy any
2910 internal headers. Affected file Makefile.defines.pre and all
2911 Makefile.am's under lib/ and subdirs.
2913 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Do not change the ~/.silc directory's permissions automatically.
2916 Affected file irssi/src/silc/core/clientutil.c.
2918 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * Do not cancel the protocol in silc_server_close_connection
2921 it might cause recursion. Now cancelled in the function
2922 silc_server_free_sock_user_data. Affected file silcd/server.c.
2924 * Fixed the silc_server_remove_clients_by_server to regenerate
2925 the channel keys correctly finally. Added also new function
2926 silc_server_remove_clients_channels to actually do it.
2927 Affected file silcd/server.c.
2929 * Fixed the silc_server_new_channel to not crash by giving
2930 wrong router to the new channel. Affected file is
2931 silcd/packet_receive.c.
2933 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2936 which is given as argument to the silc_client_alloc now.
2937 It can be used to configure the client and set various parameters
2938 that affect the function of the client.
2940 * The USERS command in server did not check whether the channel
2941 is private or secret. Affected file silcd/command.c.
2943 * Added new argument to the USERS command in protocol specification.
2944 The USERS command now can take the channel name as argument
2945 as well. Added support for this in client and server and
2946 updated the protocol specs.
2948 * Completed the GETKEY command in client. It can be now used
2949 to fetch also servers public key not only some clients.
2950 Affected files lib/silcclient/command[_reply].c.
2952 * Added silc_client_get_server to return server entry by the
2953 server name. Affected files lib/silcclient/silcapi.h and
2956 * Redefined the IDENTIFY command in protocol specification to be
2957 more generic. It now can be used to query information about
2958 any entity in the SILC Network, including clients, servers and
2959 channels. The query may be based either the entity's name
2960 or the ID. Added support for this in both client and server.
2962 Affected files silcd/command.c and lib/silcclient/command.c
2963 and command_reply.c.
2965 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2966 the _from_client and _from_server functions. Affected file
2969 * Added silc_client_get_channel_by_id_resolve to the file
2970 lib/silcclient/silcapi.h to resolve channel information by
2971 its ID. Added also silc_client_get_channel_by_id that
2972 does not resolve it from the server.
2974 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Added SilcServerEntry context into the client library
2977 to represent one server. The INFO command now allocates
2978 these to save the resolved server info. For now on the
2979 client library will also keep information about servers,
2980 connected and resolved with INFO.
2982 The INFO command now allocates the SilcServerEntry context
2983 and saves the server info there. The COMMAND_REPLY in
2984 the INFO now returns the parameters to application in
2985 same order as defined in the protocol specification.
2987 The entries are cached in the client->server_cache.
2989 * The INFO command is now issued after received the Client ID
2990 from the server. Affected file lib/silcclient/client.c.
2992 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2993 to the application as the mode changer might be server.
2994 It is guaranteed that NULL is not returned anymore to the
2995 application. Affected file lib/silcclient/client_notify.c.
2997 The ID Type is now also passed to the application so that
2998 it can check whether the returned entry is SilcClientEntry
3001 Added new function silc_client_get_server_by_id to return
3002 the server entry by ID. Affected files are the
3003 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3005 * Do not create the channel in the Irssi SILC Client when issuing
3006 the JOIN command but when received the sucessful JOIN command
3007 reply. Otherwise the channel might get created even though we
3008 could not join it. The Affected file is
3009 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3011 * Fixed a channel joining bug in router. The router must also
3012 check the channel modes, invite and ban lists etc. when serving
3013 the JOIN command sent by normal server. Affected file is
3014 silcd/command.c. The router now resolves the client's
3015 information from the server who sent the JOIN command if it
3016 does not know it, and processes the JOIN command only after
3019 * Changed the SilcCommandCb to take new argument; void *context2.
3020 Affected file lib/silccore/silccommand.h
3022 The second argument in the command callbacks in the server now
3023 includes the SilcServerCommandReplyContext if the command was
3024 called as pending command callback from the command reply.
3025 Otherwise it is NULL. When called as pending the status of the
3026 command reply will be checked and if it was erronous the
3027 error will be sent to the original sender of the command.
3028 This way the client always receives the error messages even
3029 though the server was actually the one who received the error
3030 when it resent the command to router, for example. Affected
3031 files silcd/command[_reply].[ch].
3033 * Fixed sending WHOWAS command's error message to client if
3034 the requested client could not be found. It was missing.
3037 * Changed the CMODE and CUMODE commands reply arguments in the
3038 protocol specification. The Channel ID is now sent in both
3039 of the commands to identify the channel. Implemented this
3040 new feature to the client and server. Affected files
3041 lib/silcclient/command_reply.c and silcd/command.c.
3043 * Made better checks for invite and ban lists in the JOIN
3044 command in server. Affected file silcd/command.c.
3046 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * The server now performs the incoming host IP/DNS lookup
3049 using the silc_socket_host_lookup and thus does not block
3050 the server anymore. Affected file silcd/server.c.
3052 * Completed the multi-thread support for SILC Scheduler in
3053 the lib/silcutil/silcschedule.c.
3055 * Fixed the configure.in.pre to detect the pthread correctly
3058 * Fixed a deadlock in silc_task_queue_wakeup in the file
3059 lib/silcutil/silctask.c.
3061 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Added new function silc_schedule_wakeup that is used in
3064 multi-threaded environment to wakeup the main thread's
3065 schduler. It needs to be used when a thread adds a new task
3066 or removes a task from task queues. After waking up, the
3067 scheduler will detect the task queue changes. If threads
3068 support is not compiled in this function has no effect.
3069 Implemented the wakeup mechanism to both Unix and WIN32
3070 systems. Affected files are lib/silcutil/silcschedule.[ch],
3071 lib/silcutil/unix/silcunixschedule.c and the
3072 lib/silcutil/win32/silcwin32schedule.c.
3074 * Added new function silc_task_queue_wakeup to wakeup the
3075 scheduler by the specified task queue. Affected file
3076 lib/silcutil/silctask.[ch].
3078 * The silc_socket_host_lookup_start now wakes up the scheduler
3079 after adding the timeout task. Affected file is
3080 lib/silcutil/silcsockconn.c.
3082 * The silc_socket_host_lookup is synchronous now if the threads
3083 support is not compiled in. However, the callback is still
3084 called asyncronously through the scheduler, anyway. Affected
3085 file lib/silcutil/silcsockconn.c.
3087 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Added new function silc_socket_host_lookup to perform
3090 asynchronous IP and FQDN lookups for the socket connection.
3091 Affected files lib/silcutil/silcsockconn.[ch].
3093 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3096 that may or may not compile the mutex support in.
3098 Changed the silc_mutex_alloc interface. It allocates the
3099 mutex now to the sent pointer and returns TRUE or FALSE.
3101 Affected file lib/silcutil/silcmutex.h.
3103 * Wrote the SILC Task Queue interface to support multi-threads.
3104 Affected file lib/silcutil/silctask.[ch].
3106 * Wrote the SILC Scheduler to support multi-threads. Affected
3107 file lib/silcutil/silcschedule.c.
3109 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3112 in lib/silcutil/win32/.
3114 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Defined SILC Mutex API and SILC Thread API and implemented
3117 them for Unix. Affected files are
3118 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3119 lib/silcutil/unix/silcunixmutex.c and
3120 lib/silcutil/unix/silcunixthread.c.
3122 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Fixed the silc_server_remove_clients_by_server's channel
3125 key re-generation. The hash table handling was incorrect
3126 and would not work with many channels. Affected file is
3129 * Fixed some memory leaks around the server code.
3131 * Rewrote the silc_server_get_users_on_channel to support IPv6
3132 based Client ID's. Affected file silcd/server.c.
3134 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3135 specification. However, a separate document must be written
3136 to define the detailed signing procedure and the payload
3137 associated with the flag. Defined the flag to the
3138 lib/silccore/silcchannel.h as well.
3140 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Changed the dynamic tables to static size tables in the
3143 lib/silccrypt/silchmac.c.
3145 * Removed GCC dependencies from the code. A patch by cras.
3147 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * Do not show the error "Error receiving packet bla bla"
3150 in server if it really was not an error (-2 means that reading
3151 is pending). Affected file silcd/server.c.
3153 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Fixed a possible crash in silc_server_remove_clients_by_server
3156 in silcd/server.c. Fixed there also some memory leaks.
3158 * Fixed the silc_idlist_replace_client_id. It could replace
3159 wrong key in the hash table. Affected file silcd/idlist.c.
3161 * Do not check whether there are global users on the channel
3162 if the channel->global_users is FALSE. Affected functions
3163 silc_server_remove_from_one_channel and
3164 silc_server_remove_from_channels in silcd/server.c. Also,
3165 do not check if the removed client is local as we can be
3166 sure that global client was not removed from the channel
3167 and checking for global users is not needed.
3169 * The silc_server_remove_clients_by_server now re-generates
3170 the channel keys correctly for those channels that had
3171 clients removed from them. Affected file silcd/server.c.
3173 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Found the reason of random crashes in the server. We weren't
3176 ignoring the SIGPIPE signal (which can be sent in write())
3177 and it crashed the server. Affected file silcd/silcd.c.
3179 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3181 * Assure that sock->user_data is not NULL in the function
3182 silc_server_packet_send in silcd/packet_send.c.
3184 * Disconnect the remote connection if it could not be added
3185 to any ID lists in the server. The affected file is
3188 * Check in silc_server_packet_send[_real/dest] that the
3189 socket is not disconnecting and ignore the data if it is.
3190 Affected file silcd/packet_send.c.
3192 * Define inline to __inline on native WIN32 compilation.
3193 Affected file includes/silcwin32.h.
3195 * Added some explicit type casts for inline code since MSVC
3196 require them. Affected files lib/silcutil/silcbuffer.h,
3197 lib/trq/silcdlist.h and lib/trq/silclist.h.
3199 * Print warning in log files from now on if the packet
3200 decryption fails. Affected file silcd/server.c.
3202 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Changed the `say' client operation's interface to accept
3205 new `type' argument to indicate the type of the message sent
3206 by the library. The application may filter the library's
3207 messages according the type. The affected file is the
3208 lib/silcclient/silcapi.h.
3210 * Added two new functions to lib/silcclient/silcapi.h:
3211 silc_client_del_client and silc_client_del_client_by_id.
3212 Affected file lib/silcclient/idlist.c.
3214 * Moved the clientincludes.h from includes/ to silc/ and
3215 serverincludes.h from includes/ to silcd/.
3217 * The modes for the CMODE and CUMODE are now passed as
3218 uint32 for application with COMMAND_REPLY. The affected
3219 file is lib/silcclient/command_reply.c.
3221 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * /WHOIS without arguments shows client's own information.
3224 Affected file lib/silcclient/command.c.
3226 * Changed PING to not accept any arguments. The specs
3227 says that client can ping only the connected server so
3228 requiring an argument is not needed. Affected file is
3229 lib/silcclient/command.c.
3231 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Fixed a fatal bug in private message sending and reception
3234 encryption and decryption when using private message keys.
3235 The implementation was incorrect and did not follow the
3236 specification. It causd that some of the message were
3237 lost since it did not use the sending and receiving keys
3238 as the protocol suggests. This has been fixed and will cause
3239 incompatibilities with older clients when sending private
3240 message encrypted with private message keys. Affected files
3241 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3242 and various other in Irssi SILC Client.
3244 Added `responder' boolean argument to the functions
3245 silc_client_add_private_message_key[_ske] to indicate when
3246 the key is added as responder or initiator of the key
3249 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3251 * Removed the silc_ske_check_version function and created
3252 a SilcSKECheckVersion callback. Added also a function
3253 silc_ske_set_callbacks that is now used to set all SKE
3254 callbacks. The callback functions are not given to
3255 the SKE functions anymore, but this function is used to
3258 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3260 * Added `silc_version' argument to the silc_client_alloc
3261 to define the version of the application for the library.
3262 The library will use the version string to compare it
3263 against the remote host's (usually a server) version
3264 string. Affected file lib/silcclient/silcapi.h
3266 * Added the KE protocol context to Key Agreement context
3267 in client library so that we can abort the SKE if it
3268 is in process when we get timeout. Affected file is
3269 lib/silcclient/client_keyagr.c.
3271 * Do not resolve the client ID forever if it returns in the
3272 first time that such client does not exist. This was done
3273 for example with private message. Affected file is
3274 lib/silcclient/client_prvmsg.c.
3276 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * Do not add regex.h for WIN32. The affected file
3279 includes/silcincludes.h.
3281 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3282 not work yet 100%. It generates the DLL's automatically
3283 when compiling with --with-win32 under cygwin.
3285 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * lib/contrib/regex.c is not compiled on WIN32.
3289 * Added silc_net_get_socket_opt function to the
3290 lib/silcutil/silcnet.h.
3292 * Added includes/silcwin32.h for WIN32 specific includes
3295 * Do not use ptime structure or any of the posix process
3296 functions on WIN32 in lib/silccrypt/silrng.c.
3298 * Added silc_gettimeofday to provide generic function
3299 for struct timeval on all platforms. Added the function
3300 to lib/silcutil/silcutil.h.
3302 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3305 library as they clearly belong there. As a plus side we
3306 can make the actual socket connection routines platform
3309 Added also new generic function silc_socket_read and
3310 silc_socket_write (that used to be silc_packet_[read/write].
3311 The implementation of these are platform specific.
3313 * Added WIN32 specific routines of silc_socket_[read/write]
3314 to lib/silcutil/win32/silcwin32sockconn.c.
3316 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Added preliminary support for native WIN32 compilation under
3319 cygwin (using the -mno-cygwin option for GCC) to the
3320 ./configure.in.pre. The --with-win32 now prepares the
3321 compilation for native WIN32.
3323 * Rewrote the SILC Scheduler interface in the file
3324 lib/silcutil/silcschedule.h. The scheduler is now context
3325 based and does not have anymore any global static scheduler.
3326 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3327 and created lib/silcutil/win32 directory for WIN32 based
3330 * Added Unix specific network routines to the
3331 lib/silcutil/unix/silcunixnet.c and the old
3332 lib/silcutil/silcnet.c includes now only generic routines.
3334 Added WIN32 specific network routines to the
3335 lib/silcutil/win32/silcwin32net.c.
3337 * Added Unix specific utility functions from the
3338 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3340 * Added WIN32 SILC Scheduler to the file
3341 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3344 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Do not handle JOIN notify in the server if the target client
3347 is not registered (idata->registered == FALSE). The affected
3348 file is silcd/packet_receive.c.
3350 * Update the nickrec->founder in event_cumode in the Irssi SILC
3351 client. Affected file irssi/src/silc/core/silc-channels.c.
3353 * Fixed the CUMODE_CHANGE notify handling in the server when
3354 server and router are announcing their clients on channels.
3355 Now the mode changes are saved and notified correctly. The
3356 affected file is /silcd/packet_receive.c.
3358 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3359 They really did not replace the cache entry in the ID Cache.
3360 Now they do that. Affected file silcd/idlist.c.
3362 * Fixed the KICK notify handling in the Irssi SILC client to
3363 update the channel records so that the kicked client does not
3364 appear to be on the channel. The affected file is
3365 irssi/src/silc/core/silc-channels.c.
3367 * Always update the conn->current_channel when executing command
3368 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3370 * Fixed the KILL notify handling in Irssi SILC client to remove
3371 the killed client on all channels.
3373 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Fixed the silc_parse_command_line to remove extra spaces
3376 from the start and end of the arguments. Affected file is
3377 lib/silcutil/silcutil.c.
3379 * Cancel and free any active protocol in the function
3380 silc_server_close_connection. Affected file silcd/server.c.
3382 * Cancel and free any active protocol in the function
3383 silc_client_close_connction. Affected file is
3384 lib/silcclient/client.c.
3386 * Do not execute the KILL command for clients that are in
3387 history (ie. they are not in the network). Affected file is
3390 * Fixed KILL notify handling, client does not crash anymore.
3391 Affected file irssi/src/silc/core/silc-channels.c.
3393 * Reduced the default packet buffer size from 2048 to 1024 in
3394 lib/silccore/silcpacket.c.
3396 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3397 counter to the SKE context that is incresed when the SKE library
3398 performs async operation outside the library. If the outside
3399 process frees the SKE context and FREED status will be set
3400 and the library will detect after the sync operation that the
3401 libary is freed. The affected files are
3402 lib/silcske/silcske[_status].[ch].
3404 * Resolve the client entry information in the function
3405 silc_client_channel_message to assure that NULL pointer is not
3406 passed as client entry to the application. */
3408 * Fixed the task timeout calculation to assure that there is
3409 never negative timeouts. The affected file is
3410 lib/silcutil/silcschedule.c.
3412 * Fixed the channel user mode notification sending in server.
3413 It was sent point-to-point to the router (or to server by router)
3414 but it needs to be destined to a channel. The routines now
3415 supports sending the channel user mode notifys to the channels
3416 when announcing clients and channels. Affected files are
3417 silcd/server.c and silcd/packet_receive.c.
3419 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3420 It did not actually replace the old channel entry in the cache.
3421 Affected file lib/silcclient/client_notify.c.
3423 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * Fixed a possible crash in silc_packet_send_prepare. It now
3426 assures always that there is enough space in the buffer and
3427 at the tail area of the buffer (for MAC).
3429 Fixed the inbound buffer reallocation in silc_packet_read.
3430 It was old code and did not handle the reallocation correctly.
3433 The affected file is lib/silccore/silcpacket.c.
3435 * Fixed buffer overflow in silc_parse_nickname in the file
3436 lib/silcutil/silcutil.c.
3438 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * make install generates new server keys only if there is not
3443 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3446 Added check that if the NOREPLY is set then we will not send
3447 the away message. This avoids infinite loop of away messages
3448 if both clients are away. The affected file is
3449 lib/silcclient/client_prvmsg.c.
3451 * Fixed client crash if /NICK was given without arguments.
3452 Affected file lib/silcclient/command.c.
3454 * Server does not send the invite list in INVITE command back
3455 to the client if the list was not altered. Added this notion
3456 to the protocol spec as well. Affected file silcd/command.c.
3458 Fixed possible crash in INVITE command by checking the
3459 value of silc_server_get_client_route command.
3461 * Fixed the INVITE notify type handling. The arguments are now
3462 taken in correct order and client does not crash. The affected
3463 file is irssi/src/silc/core/silc-channels.c.
3465 Removed the "Inviting xxx to channel" message from the
3466 client library away and let the application handle it.
3467 Affected file lib/silcclient/command.c. Added that message
3468 to Irssi SILC client's message formats.
3470 * Fixed CMODE command crash in client. It now checks the
3471 amount of arguments correctly and does not crash. The affected
3472 file is lib/silcclient/command.c.
3474 * Do not create new channel automatically in silc_channels_join
3475 but check whether the channel by that name already exists.
3476 Affected file irssi/silc/core/silc-channels.c.
3478 * Do not send the SERVER_SIGNOFF to router if the disconnected
3479 entity was the router. Affected file silcd/server.c.
3481 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3482 SILC client as it was missing from there.
3484 Added the handling of the KICK notify to the Irssi SILC client
3485 as it was missing. Added "you have been kicked" message to
3486 Irssi SILC client's message modules formats.
3488 Added the handing of the KILL notify to the Irssi SILC client
3489 as it was missing. Added the kill message module formats
3492 The affected file is irssi/src/silc/core/silc-channels.c.
3494 * The router did not save the channel mode the server announced.
3495 Affected file silcd/packet_receive.c.
3497 * Fixed a possible crash in INFO command in server. If the
3498 server did not provide the server info it crashed. Affected
3499 file silcd/command.c.
3501 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Fixed the GETKEY command in the server to check also the
3504 global list. Otherwise the GETKEY would not work correctly
3505 in normal SILC server. Affected file silcd/command.c.
3507 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3509 * Fixed GETKEY crash, it crashed if the command did not succseed.
3511 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3514 is now real and not just an macro interface to GMP.
3516 Removed the entire GMP from the source tree and imported new
3517 NSS MPI library instead. Reason for removing GMP is that it is
3518 extremely large and compiles extremely slow. The NSS MPI
3519 is only a few files and compiles in less than 10 seconds.
3520 The speed is also about the same as GMP. The MPI is imported
3521 to lib/silcmath/mpi.
3523 If the system has GMP installed we will still use the GMP.
3524 If it is not then the NSS MPI will be compiled.
3526 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Merged a long nickname (127 characters long) crash bugfix from
3529 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3531 * Merged a freed memory reference bugfix from Irssi CVS tree.
3532 Affected file irssi/src/core/commands.c.
3534 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Added the server's public key sving and verification to the
3537 server when performing the SKE. This was missing and the
3538 remote server's (or router's) public key was accepted without
3539 checking whether we have it previously or trust it at all.
3540 Affected file silcd/protocol.c.
3542 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Check in the silc_server_timeout_remote if protocol is active
3545 and make sure that the protocol's final callback is called so
3546 that all memory if freed. Affected file silcd/server.c.
3548 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3550 * silc_server_whois_send_reply crashed the server if the nickname
3551 was 127 characters long. Affected file silcd/command.c.
3553 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added sanity check to the silc_server_new_client. If the hostname
3556 is provided inside username then check that the provided hostname
3557 really is the same as the resolved one. If the hostname was not
3558 resolved then check it from the public key. Affected file is
3559 silcd/packet_receive.c.
3561 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3562 if the server disconnected us and the connection is not valid
3563 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3565 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3566 the library to the lib/silcutil/silcutil.[ch].
3568 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3570 * Close log file after open. Affected file
3571 lib/silcutil/silclog.c.
3573 * Check whether sock == NULL in silc_client_send_packet and return
3574 if it is. Affected file lib/silcclient/silcclient.c.
3576 * Check rec->entry == NULL in the Irssi SILC Client before
3577 sending the channel message. Affecte file is
3578 irssi/src/silc/core/silc-servers.c.
3580 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Merged a splitted window bugfix from Irssi CVS tree. The
3583 affected file is irssi/src/fe-text/textbuffer-view.c.
3585 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3586 It did not print nickname.
3588 * Improved the distributions system a bit.
3590 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3593 irssi/src/fe-text/gui-window.c.
3595 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3596 to in-active server. The affected file is
3597 irssi/src/silc/core/client_ops.c.
3599 * Resolve the client in USERS command reply if the entry does
3600 not have username resolved. The affected file is
3601 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3602 command to WHOIS command to really resolve stuff. The USERS
3603 is not used any more in any critical section so WHOIS can
3604 be used even though it might be slower than IDENTIFY.
3606 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3609 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Changed the protocol API a bit more consistent in the
3612 lib/silccore/silcprotocol.[ch].
3614 * Changed the following headers to ROBODoc format:
3616 lib/silccore/silcpayload.h
3617 lib/silccore/silcprotocol.h
3618 lib/silccore/silcsockconn.h
3620 All core library headers are now formatted.
3622 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Fixed a bug in Irssi SILC client; do not show that you are
3625 server/router operator if you really are not. Affected file is
3626 irssi/src/silc/core/client_ops.c.
3628 * Renamed silc_command_free_payload to silc_command_payload_free.
3629 Affected file lib/silccore/silccommand.h
3631 * Added silcmath.h to include the prototoypes of various routines
3632 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3635 * Changed the following headers to ROBODoc format:
3637 lib/silccore/silcchannel.h
3638 lib/silccore/silccommand.h
3639 lib/silccore/silcid.h
3640 lib/silccore/silcidcache.h
3641 lib/silccore/silcmode.h
3642 lib/silccore/silcnotify.h
3643 lib/silccore/silcpacket.h
3644 lib/silcmath/silcmath.h
3646 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added checking to the server code not to start the server if
3649 ciphers and stuff are not configured properly. Affected files
3650 silcd/serverconfig.[h] and silcd/server.c.
3652 * Changed the layout of the header files of the public interfaces
3653 in the SILC libraries. The new layout supports ROBODoc
3654 documentation tool (and some others) so that it is easy to create
3655 a library reference manual. All the other headers and source
3656 code must still follow the CodingStyle document. Also source
3657 code must not include these ROBODoc stuffs, only the headers.
3658 Furthermore, all public interface headers must now be named
3659 by using `silc' prefix, example: silcapi.h, silccipher.h.
3660 Some files were renamed due to this. All the other headers
3661 must not be used as public interfaces. I will update the
3662 CodingStyle document later. Changed following headers, so far:
3664 lib/silcclient/silcapi.h
3665 lib/silccore/silcauth.h
3666 lib/silccore/silcprivate.h
3667 lib/silccrypt/silcdh.h
3669 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Removed silc_client_packet_send_flush from the client library
3674 as it is not needed. Affected file lib/silcclient/client.[ch].
3676 * Added printing of message of unresolved authentication method
3677 to the Irssi SILC client. Added it to the module formats.
3678 Removed the same message from the client library.
3680 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Added new distribution feature, DISTLABEL. Every distribution
3683 can define own preprocessor label that can be used in the
3684 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3685 file distributions, acconfig.h.pre and prepare.
3687 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added Makefile.defines_int to include the actual definitions
3690 for Makefile.defines.in. Tested the new distribution system,
3691 created distributions and tested installation.
3693 * Added AWAY message printing to the Irssi SILC client. Added
3694 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3696 * Added SCONNECT command to call the SILC's CONNECT command.
3697 Cannot use CONNECT directly since Irssi uses that internally.
3698 Affected file irssi/src/silc/core/silc-servers.c.
3700 Added ACTION local command. It is same as ME command but takes
3701 the channel as mandatory argument.
3703 Rewrote some of the Irssi's help files to suite for SILC
3706 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added Makefile.defines[.in] that should for now on be included
3709 in all Makefile.am file in the source tree. That file includes
3710 all common compilation definitions for SILC source tree.
3712 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Minor changes to the ./prepare script to change the package
3715 name according the distribution name to the configure.in.
3717 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Created new distribution system. Added file `distributions'
3720 that defines all the distributions that can be created out of
3721 the SILC source tree. The ./prepare script now reads that
3722 file to determine how to prepare the distributions. The
3723 first argument to the ./prepare is the name of the distribution
3724 and second is the version of the distribution. If given
3725 without arguments it creates the default (toolkit) distribution
3726 with the default version (defined in ./prepare).
3728 All Makefile.am files that are subject to the distributions
3729 are now named as Makefile.am.pre. These are ./Makefile.am
3730 and lib/Makefile.am. Others may be changed later.
3732 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added invite list, ban list, some key management and connection
3735 error message printing to module formats in the Irssi SILC client.
3737 * Added new silc_client_set_away_message to set the away message
3738 that is back to the person who sent private message. The
3739 affected file lib/silcclient/silcapi.h and the
3740 lib/silcclient/client_prvmsg.c.
3742 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Fixed the private message sending in the Irssi SILC client,
3745 added local command KEY to the Irssi SILC client.
3747 Added key management and key agreement message formats to the
3748 irssi/src/fe-common/silc/module-formats.[ch].
3750 Added USERS (alias WHO) printing, server/router operator
3751 indication and LIST command printing to the module formats.
3753 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Fixed channel joining notify handling, cumode notify handling
3756 from Irssi SILC client.
3758 * Added SILC specific module-formats to the Irssi SILC client so
3759 that SILC specific message hilighting, colors etc is possible.
3760 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3762 Added channel mode, channel user mode, actions, notices,
3763 whois and whowas printing to the the module-formats.c.
3765 * Fixed a bug in channel deletion in the server. The channel
3766 is not left to the cache even if the channel founder auth mode
3767 is set when there are no users anymore on the channel. Affected
3768 file silcd/server.c.
3770 * The silc_net_localhost now resolves the entire hostname including
3771 the domain name. Affected file lib/silcutil/silcnet.c.
3773 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Changed the ask_passphrase client operation to be ascynchronous.
3776 It has now a completion callback and a context that the
3777 application must call after it has got the passphrase from
3778 the user. Affected files lib/silcclient/silcapi.h,
3779 lib/silcclient/protocol.c, lib/silcclient/command.c and
3782 Added SilcAskPassphrase callback that the application calls
3783 to deliver the passphrase to the library.
3785 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3786 The public key verification and especially a certificate
3787 verification is asynchronous procedure.
3789 Added new SILC_SKE_STATUS_PENDING status to indicate the
3790 request is pending and a callback will be called to finalize
3793 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3794 indicate that remote end did not send its public key (or
3795 certificate), even though we require it. Added check for this
3796 condition in the SKE. This was a security bug, now fixed.
3798 Defined new SilcSKEVerifyCbCompletion callback that is called
3799 when the verification process is completed.
3801 The affected files lib/silcske/silcske_status.h and
3802 lib/silcske/silcske.[ch].
3804 * Changed the verify_public_key client operation to be async
3805 as well. Defined SilcVerifyPublicKey callback that is used to
3806 indicate the success of the public key verification process.
3808 Changed the server and client to use the new async client
3811 * Changed the Irssi SILC client's internal scheduler to be called
3812 twice as many times as it used to be. As a result the client
3813 should be a bit faster now. Affected file is
3814 irssi/src/silc/core/silc-core.c.
3816 * Added support to Irssi SILC client of asynchronous public key
3817 verification and passphrase inquiry. Affected file is
3818 irssi/src/silc/core/silc-core.c.
3820 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Do not say "You have left channel %s" in client library.
3823 Moved it to the application. Affected files are
3824 lib/silcclient/command.c and silc/client_ops.c.
3826 * Fixed silc_client_get_clients. Command context was not
3827 duplicated and was freed memory in the callback. Affected
3828 file lib/silcclient/idlist.c.
3830 * Do not say "you are now talking..." on JOIN command in the
3831 client library. The appliation must handle it.
3833 * Do not say ".. changed topic to" in command reply in the
3834 client libary. The application must handle it.
3836 * Fixed TOPIC command sending in the client library.
3838 * Fixed a memory leak in silc_client_command_free in the file
3839 lib/silcclient/command.c.
3841 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3843 * Imported a modified version of Irssi client to the source tree.
3844 The Irssi will be used to create a new client called
3845 Irssi SILC. Imported to irssi/.
3847 Added silc_core_init_finish function to the Irssi. Affected
3848 file irssi/configure.in.
3850 A lot changes in the Makefile.ams around the irssi tree.
3852 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Do not rehash if the new size is same as the old size of the
3855 hash table, in the silc_hash_table_rehash*. The affected file
3856 lib/silcutil/silchashtable.c.
3858 * Replaced hash_table_del_by_context calls from the server
3859 (when channel->user_list and client->channels) to the
3860 hash_table_del as it is sufficient and faster.
3862 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added silc_hash_table_list, silc_hash_table_get and the
3865 SilcHashTableList structure to provide an alternative way to
3866 traverse the hash table. The affected files are
3867 lib/silcutil/silchashtable.[ch].
3869 * Changed the server's idlist routines to use the hash table
3870 routines to optimize the code.
3872 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Replaced the client entry's `channel' list and channel entry's
3875 `user_list' list to hash tables for optimized lookup. Changed
3876 the code to use the hash table interface around the code.
3877 Affected file lib/silcd/idlist.[ch].
3879 * Added `auto_rehash' boolean argument to the function
3880 silc_hash_table_alloc to indicate whether the hash table should
3881 auto-rehash when it thinks is appropriate time. It will
3882 increase the hash table size if the there is twice as much
3883 entries in the table than the size of the table, and will
3884 decrease the size if there are twice as less entries than
3885 the size of the table.
3887 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3891 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * silc_idcache_purge_by_context deletes the entry now by context
3894 as it is supposed to do. Affected file lib/silccore/idcache.c.
3896 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3897 client is not anymore valid (WHOWAS givens the info) and not
3898 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3900 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Removed the `data' and `data_len' arguments from the ID Cache
3903 interfaces and added `name' argument. ID Cache does not handle
3904 anymore the binary data only a names associated with given ID.
3906 * When hashing a Client ID with silc_hash_id the entire ID is
3907 not hashed anymore, instead only the hash of the Client ID is
3908 hashed. This way we can access the Client ID from the cache
3909 with Client ID but with the hash of the ID (which is a hash of
3910 the nickname) as well without any difference in performance.
3912 Added also silc_idcache_find_by_id_one_ext to do one on one
3913 searching when we have the actual ID. Added also function
3914 silc_hash_client_id_compare. The affected files are
3915 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3917 * When hashing the name associated with a ID it is always done
3918 in lowercase. This way we can access the cache without worrying
3919 about case-sensitivity, even though, for example nicknames are
3922 * Fixed a bug in server with channel message sending. It put
3923 wrong ID type as destination ID. The affected file
3924 silcd/packet_send.c.
3926 * silc_idcache_del_by_context now deletes from all hash tables
3927 by context. Affected file lib/silccore/idcache.c.
3929 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Changed the client library to use the new ID Cache interface.
3932 Changes around the source tree.
3934 * Added silc_hash_table_rehash_ext to rehash with specific
3935 hash function. Affected file lib/silcutil/silchashtable.[ch].
3937 * Added silc_hash_string_compare to compare two strings in the
3938 hash table. Affected file lib/silcutil/silcutil.[ch].
3940 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Added new function silc_idcache_del_by_context into the
3943 lib/silccore/idcache.[ch].
3945 * Changed the server's ID list routines to use the new ID Cache
3946 interface. Changes around the source tree.
3948 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Added silc_hash_table_del[_by_context]_ext functions in to the
3951 lib/silcutil/silchashtable.[ch].
3953 Removed silc_hash_table_find_all* routines and added new
3954 silc_hash_table_find_foreach to replace them.
3956 Added silc_hash_table_replace_ext function as extended
3957 replacing function. Separated the simple hash table interface
3958 from the extended hash table interface in the file
3959 lib/silcutil/silchashtable.h.
3961 * Fixed minor bugs and changed it to use some of the new
3962 hash table functions in lib/silccore/idcache.c
3964 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Added new function silc_hash_table_find_all to return all keys
3967 in the hash table by the specified key. As the hash table is
3968 collision resistant it also makes it possible to have several
3969 duplicate keys in the hash table. This function may be used to
3970 find all of the keys from the hash.
3972 Added user_context arguments to the SilcHashFunction,
3973 SilcHashCompare and SilcHashDestructor to deliver user specified
3976 Added new fuctions silc_hash_table_find[_all]_ext to do
3977 extended lookup with specified hash and compare functions and
3978 specified user contexts.
3980 Added new function silc_hash_table_add_ext to add the key
3981 with specified hash function and user context.
3983 Added new function silc_hash_table_foreach to traverse all
3984 entrys in the hash table. Added SilcHashForeach callback
3987 Added new function silc_hash_table_del_by_context to delete
3988 the entry only if the context associated with the key matches.
3990 Affected files are lib/silcutil/silchashtable.[ch].
3992 * Removed silc_hash_[server/client/channel]_id and added just
3993 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3994 silc_hash_id_compare to compare two ID's using as the hash table
3995 comparison function. Added also silc_hash_data to hash
3996 binary data and silc_hash_data_compare to compare it.
3998 * Removed silc_idlist_find_client_by_hash as it is not needed
3999 anymore. Affected file silcd/idlist.[ch].
4001 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4002 to use internally the SilcHashTable. The new ID Cache is a lot
4003 faster than the old one. Some of the ID Cache interface was also
4004 rewritten and obsolete and stupid functions were removed.
4006 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Added entry_count field to the SilcHashTable to keep the number
4009 of the entries in the table. Implemented the function
4010 silc_hash_table_rehash. Added new function
4011 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4013 Fixed a minor bug in silc_hash_table_free.
4015 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4016 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4017 into the lib/silcutil/silcutil.[ch].
4019 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Implemented a collision resistant hash table into the
4022 lib/silcutil/silchashtable[ch]. See the header and the source
4023 for the SilcHashTable API.
4025 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Merged dotconf version 1.0.2 into lib/dotconf.
4029 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Do not compile anything in lib/silcsim/* if the SIM support
4032 is not enabled. The tree should now compile without problems
4035 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Compiled the SILC under cygwin. Compiled and tested briefly
4038 without problems. More tests needed. The SIMs didn't compile
4041 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4043 * Fixed possible crash in silc_get_username in the
4044 lib/silcutil/silcutil.c.
4046 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Fixed a va_arg in silc/client_ops.c.
4050 * Oops, RC5 routines were named AES and caused some problems
4051 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4053 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Added new SilcIDIP structure into the lib/silccore/id.h and
4056 replaced the old `ip' fields from all SILC ID's to that type.
4057 This is a step towards IPv6 support.
4059 The silc_id_get_len takes now the ID as an extra argument.
4060 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4061 both IPv4 and IPv6 based ID's.
4063 The affected files are lib/silccore/id.[ch] and other files
4064 around the tree using these routines.
4066 * Removed the ID length arguments in server from various
4067 silc_server_send_notify_* routines -> they are not needed
4070 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Fixed memory leak in silc_encode_pem_file in the file
4073 lib/silcutil/silcutil.c.
4075 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Check minor version as well in the SKE. Affected files are
4078 silcd/protocol.c and lib/silcclient/protocol.c.
4080 * Added --identifier option to the server so that an identifier
4081 can be when creating the public key for the server. Affected
4082 file is silcd/silcd.c.
4084 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4085 lib/silccrypt/silcpkcs.c.
4087 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4089 * Register default ciphers and stuff when using -C option with
4090 the server. Affected file sildc/silcd.c.
4092 * Put back the servers public key filename format, it is better
4093 than the new one. For now, the client keys are saved with the
4094 new filename format. The affected file silc/client_ops.c.
4096 * Implemented the Cipher API for the rest of the ciphers that
4097 did not implement it or implemented it the wrong way.
4099 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Register default ciphers and stuff when using the -S option
4102 in the client. Affected file silc/silc.c. Same also when
4103 creating new key pair with -C option.
4105 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Fixed the silc_verify_public_key client operation function to
4108 save the public keys differently. The fingerprint is now
4109 used as filename and not the hostname. This way also the
4110 client keys are saved uniquely and not with hostnames. The
4111 affected file is silc/client_ops.c.
4113 * Trimmed the silc_hash_fingerprint function to remove extra
4114 whitespaces from the end of the fingerprint. The affected
4115 file is lib/silccrypt/silchash.c.
4119 * Added silc_cipher_register_default function to register all
4120 default ciphers. It can be used when configuration files
4121 does not exist and the application does not want any specific
4122 ciphers in any specific order.
4124 The SilcDList is now used as silc_cipher_list dynamically
4125 allocated cipher list. Removed the static list all together
4126 and now all ciphers must be allocated to the dynamic list.
4127 The silc_cipher_alloc routine was changed to check only the
4130 All silc_cipher_* routines that used to return int returns
4133 The affected files lib/silccrypt/silccrypt.[ch].
4135 * The same thing was done to silc_hash_* as for silc_cipher_*
4136 routines. Affected files lib/silccrypt/silchash.[ch].
4138 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4139 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4140 Added also silc_pkcs_[un]register[_default] functions.
4141 Removed the data_context from the PKCS API.
4143 * Added silc_hmac_register_default function to register default
4144 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4145 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4146 to unregister all hmacs at once.
4148 * Register the default ciphers, hash functions, PKCSs and HMACs
4149 if client's configuration file does not exist. The affected
4152 * The client did not load the hash functions from the SIM
4153 modules at all. Added support for this. Affected file is
4154 silc/clientconfig.c.
4156 * When decoding public key with silc_pkcs_public_key_decode, check
4157 the supported algorithm only if PKCS are registered. Affected
4158 file lib/silccrypt/silcpkcs.c. The same was done with the
4159 silc_pkcs_private_key_decode.
4161 * Fixed the SILC List routines to keep the list always in order.
4162 It used to change the list's order when traversing the list but
4163 not it preserves the order. Affected file lib/trq/silclist.h.
4165 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Added the client library to use the SilcSocketConnection's
4168 reference counter (by silc_socket_dup) to prevent the bug that
4169 the socket object may be freed underneath async operation.
4171 * The name resolv library checking fixes in the configure.in.pre.
4174 * Created new version of the protocol drafts for future
4175 development. The -03 drafts are the ones that will be changed
4176 in the trunk now and the -02 will remain as they are.
4178 * Send list of CUMODE notifys to the router when announcing
4179 the channel users to the router. Affected file silcd/server.c.
4180 If the router receiving channel founder CUMODE for a channel
4181 that already has channel founder it will send CUMODE notify
4182 to the sender to remove the channel founder rights from the
4183 announced client. Affected file silcd/packet_receive.c.
4185 * The CUMODE notify may now use Server ID as well as the entity
4186 who changes the mode. Updated protocool specs.
4188 * Updated INSTALL and README files.
4190 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4192 * New web pages in the http://silc.pspt.fi. The pages was
4197 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Implemented the [DenyConnectin] config section in the server.
4200 Added silc_server_config_denied_conn to check whether incoming
4201 connection is denied. Affected file silcd/serverconfig.[ch].
4203 * Do not check the ports when checking the incoming configuration
4204 data if the port is 0, meaning any. Affected file is
4205 silcd/serverconfig.c.
4207 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Fixed buffer overflow in silc_string_compare in the file
4210 lib/silcutil/silcutil.c.
4212 * Fixed double free in silc_server_command_leave in the file
4215 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Fixed the version checking in the server. Affected file is
4220 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed the configuration data fetching when accepting new
4223 connections in the server. Affected file silcd/server.c.
4225 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added `sender_entry' argument to the function
4228 silc_server_packet_relay_to_channel so that we can check
4229 whether some destination actually belongs to the same route
4230 the sender belongs (ie, we must not resend the packet to the
4231 sender). Affected file silcd/packet_send.[ch].
4233 * Added `servername' field to the SilcClientEntry in the server
4234 to hold the name of the server where client is from. Affected
4235 file is silcd/idlist.h.
4237 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Moved the channel message encrypting in the router betwen
4240 router connections from silc_server_channel_message to the
4241 silc_server_packet_relay_to_channel since we want to check
4242 whether we have anybody channel before encrypting anything.
4243 Affected files silcd/packet_[receive/send].c.
4245 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Fixed the [AdminConnection] server config section to support
4248 multiple entries. Affected file silcd/serverconfig.c.
4250 * Added support into the server to check the validity of the
4251 incoming connection before executing any KE or authentication
4254 * The connection configuration is now saved to the KE and
4255 connection auth protocol contexts and not fetched anymore in
4256 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4258 * The local hosts listenning address and port is also resolved
4259 now when starting the server. We want to have the socket object
4260 to include the real address and port for the listener. Added
4261 new function silc_net_check_local_by_sock into the files
4262 lib/silcutil/silcnet.[ch].
4264 * Fixed a broadcast bug in server -> do not broadcast if we
4267 * Fixed a routing bug. Do not route broadcast packets ever.
4268 Broadcast packets must be processed always and not routed since
4269 they may be destined to some other host than yourself and thus
4270 would get routed without no good reason. Affected file is
4273 * Added function silc_server_config_is_primary_route to check
4274 whether primary router connection has been configured (a router
4275 configuration that we are initiating). If there is not, we
4276 will assume that there is only two routers in the SILC network
4277 and we will use the incoming router connection as our primary
4278 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4280 * Changed the order of the broadcasting. Broadcast _after_ the
4281 packet has been processed not before. Affected file is
4284 * Fixed a [ClientConnection] parsing bug. The port was never
4285 parsed correctly thus resulting to port 0. Affected file
4286 silcd/serverconfig.c.
4288 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4289 argument and did not set the broadcast packet flag. Affected
4290 file silcd/packet_send.c. Fixed same bug in the function
4291 silc_server_send_notify as well.
4293 * If we receive NEW_ID packet for our own ID in the server, ignore
4296 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Removed the nickname from the Private Message Payload.
4301 Updated the code and the protocol specs.
4303 * Updated protocol specs for submitting to the IETF.
4305 * Tweaked the Random Number Generator a bit. Affected file
4306 lib/silccrypt/silcrng.c. Exported a new function
4307 silc_rng_[global]_add_noise which can be used to add more
4310 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Do not parse packets with different timeout when protocol
4313 is active -> may cause problem with rekey. Affected file
4316 * When server receives signoff notify it must not create
4317 new channel key if the client is on any channels since the
4318 sender of the signoff notify will create it.
4320 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Added printing of error messages during SKE protocol from the
4323 failure packet sent by server during SKE. Affected file
4326 * Removed the client's failure_callback handling with timeout
4327 and handle it immediately when received.
4329 * The SKE library returned wrong type in SUCCESS and FAILURE
4330 packets. They must be 32 bit MSB not 16 bit MSB.
4332 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Ok, rewrote the logic of the re-key and now it seems to work.
4335 I tested it on high traffic with frequent re-keys without
4336 problems. Added hmac_receive (and renamed hmac to hmac_send)
4337 in SilcClientConnection in lib/silcclient/client.h and
4338 in SilcIDListData in silcd/idlist.h. Also, removed the
4339 SilcPacketParserContext's cipher and hmac fields as they are
4340 not needed anymore and actually caused some problems when
4341 the ciphers and hmac's changed underneath the packet parser.
4343 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * If re-key protocol is active then process the incoming packets
4346 synchronously since we must assure that icoming packets encrypted
4347 with the old key is processed before the new keys is set to
4348 use. This is true other packets than for REKEY packets.
4349 Affected file silcd/server.c. The same was done to client library
4350 as well, affected file lib/silcclient/client.c.
4352 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Fixed bug in client and server to accept the force send if
4355 the packet is send from silc_[server/client]_packet_process
4356 function. Otherwise the packets are never delivered, oops.
4358 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Disable force sending of packets when REKEY protocol is active.
4361 We must assure that no packet is sent directly when rekey is
4362 performed. All packets must be sent through packet queue.
4363 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4364 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4365 function is silc_[server/client]_packet_send_real to check
4368 * Replaced the SIM paths from example config files to
4369 /usr/local/modules. Also, make install creates now
4370 /usr/local/silc/logs directory to hold all the SILC server
4373 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Made the configure.in.pre work on Solaris. Patch by salo.
4377 * Made all ciphers compatible with non-x86 machines. Defined
4378 CBC mode macros into lib/silccrypt/ciphers_def.h.
4380 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Fixed the make install.
4384 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * When MAC computation fails the silc_packet_decrypt returned 0
4387 even though it was supposed to return -1. Fixed this. The
4388 affected file is lib/silccore/silcpacket.c.
4390 * Do not replace the config files in /etc/silc (in make install)
4391 if they already exist. Affected file ./Makefile.am.
4393 * Do not send re-key packets immediately but through packet queue.
4394 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4396 * Changed silc_net_check_host_by_sock to return FALSE if the
4397 IP/DNS could not be resolved. Though, it returns the IP address
4398 now even if it could not resolve it (but returns also FALSE).
4399 Affected file lib/silcutil/silcnet.[ch].
4401 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Added silc_pkcs_decode_identifier to decode the public key's
4404 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4405 Added also silc_pkcs_free_identifier. Added also new context
4406 SilcPublicKeyIdentifier.
4408 * Added -S option to the silc client. It is used to dump the
4409 contents of the specified public key file.
4411 * Changed the PKCS api to return the public key length when
4412 setting the public key.
4414 * Fixed a fatal bug in the public and private key file loading.
4415 Affected file lib/silccrypt/silcpkcs.c.
4417 * Execute the packet parsing for client with zero (0) timeout
4418 if the protocol is active. Affected file silcd/server.c.
4420 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Made the key generation options to the silcd program. Added
4423 -C option, equivalent to client's option.
4425 * Added new [ServerKeys] config section to the server. It
4426 configures the server's public and private key.
4428 * Defined generic Public Key Payload into the protocol
4429 specification to send specific type of public keys and
4432 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4433 public key or certificate.
4435 * Implemented the GETKEY command to the server and to the
4436 client library and on user interface.
4438 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Made preliminary `make install' work.
4442 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Added SilcServerRekey context into silcd/idlist.h.
4446 * Added the PFS support as defined in the specification to the
4447 SKE protocol. Affected files lib/silcske/*.c.
4449 * Added `ske_group' field to the SilcServerRekey context to hold
4450 the number of the SKE group that is used with PFS in re-key.
4451 Affected file silcd/idlist.h.
4453 * Added PFS re-key support to the server. Affected file is
4456 * Added silc_protocol_cancel to cancel execution of the next
4457 state of the protocol. Affected file is
4458 lib/silccore/silcprotocol.[ch].
4460 * Added the re-key support with and without PFS to the client
4461 library. Re-key is performed once in an hour, by default.
4463 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4464 Added silc_client_rekey_callback and silc_client_rekey_final.
4465 Affected files are lib/silcclient/protocol.[ch] and
4466 lib/silcclient/client.[ch].
4468 * Removed the `hmac_key' and `hmac_key_len' fields from the
4469 SilcClientConnection structure; not needed. Affected file is
4470 lib/silcclient/client.h.
4474 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Do not ask whether user wants to use the negotiated private key
4477 for private messages, just use it. Affected file is
4478 silc/local_command.c.
4480 * Added `send_enc_key' and `enc_key_len' fields to the
4481 SilcIDListData structure since they are needed in the re-key
4482 phase. Affected file is silcd/idlist.[ch].
4484 * Implemented the simple re-key protocol into the server.
4485 Affected files silcd/server.c and silcd/protocol.[ch]. The
4486 re-key will be performed once in an hour, by default.
4488 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4489 Added silc_server_rekey, silc_server_rekey_callback and
4490 silc_server_rekey_final.
4492 * Removed Tunneled flag from the protocol. Updated the code
4493 and the specifications.
4495 * Adde `pfs' field to the SilcIDListData to indicate whether
4496 the PFS is to be performed in the re-key. Affected file is
4499 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4502 int64 of at least the xintXX size. If void * is less that 4
4503 bytes uint32 * will be used. Defined bool as boolean.
4505 * Changed _ALL_ unsigned long and unsigned int to uint32,
4506 unsgined short to uint16 in the source tree.
4508 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4509 not handle clients that has entry->data.registered == FALSE.
4510 They are not in the network anymore. Affected file is
4513 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Implemented the sending of the SERVER_SIGNOFF notify in the
4516 server. Affected file is silcd/server.c.
4518 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4519 Added also silc_notify_payload_encode_args into the
4520 lib/silccore/silcnotify.[ch].
4522 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4523 Affected file silcd/packet_receive.c.
4525 * Implemented the SERVER_SIGNOFF notify handling in the client
4526 library. Affected file lib/silcclient/client_notify.c. Also,
4527 implemnted the printing of the SERVER_SIGNOFF info to the
4528 application. Affected file silc/client_ops.c.
4530 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4531 if the deleting was successful. Affected file silcd/idlist.[ch].
4533 * Added support for public key authentication in the connection
4534 authentication protocol in the client library. Affected file
4535 lib/silcclient/protocol.c.
4537 * Changed the server's silc_idlist_get_clients_by_* interface
4538 to support already allocated array so that new entries may be
4539 added to pre-allocated array. Affected file silcd/idlist.[ch].
4540 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4541 and command replies.
4543 * All command reply functions in the server now calls the
4544 pending command callback even if error occured. This way the
4545 error will be delivered to the client as well. Affected files
4546 silcd/command.c and silcd/command_reply.c.
4548 * Fixed INFO command to return local server's info if no server
4549 was provided. Affected file lib/silcclient/command.c.
4551 * Removed RESTART command for good. Updated the code and the
4554 * Rewrote parts of the task system. It is a bit simpler now.
4555 Removed unsued task priorities. The affected files are
4556 lib/silcutil/silctask.[ch].
4558 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Moved the USERS printing from the library to the application.
4561 Affected files lib/silcclient/command.c and silc/client_ops.c.
4563 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added channel key re-key support. The re-key is perfomed
4568 only by the router and is done once in an hour. Added `rekey'
4569 field to the SilcChannelEntry in the server. Affected files
4570 silcd/server.c and silcd/idlist.h.
4572 * Added silc_task_unregister_by_context into the file
4573 lib/silcutil/silctask.[ch].
4575 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Added SILC_UMODE_GONE mode to indicate when the client is not
4578 present in the SILC network. Added also support to the local
4579 command AWAY that will set this mode. Added support of showing
4580 "xxx is gone" in WHOIS command. The USERS command shows the
4581 gone status as well.
4583 * Fixed setting server and router operator privileges in the
4584 server's UMODE command. Affected file silcd/command.c.
4586 * Merged the SKE KE1 and KE2 payloads into one payload. The
4587 new KE payload is equivalent to the old KE2 payload.
4589 Cleaned up the SKE Start Payload parsing. It now uses the
4590 simple buffer unformatting to do the parsing. A lot faster
4593 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4594 to the SKE that is used to indicate whether both of the SKE
4595 parties should perform authentication. By default only the
4596 responder performs authentication. By setting this flag also
4597 the initiator must do authentication. By default it is unset
4598 since in normal SKE case, client to server connection, only
4599 the responder should do authentication. When doing SKE between
4600 two clients both should perform authentication. Updated the
4601 code and the protocol specs.
4603 * A little fix to IDENTIFY command in the server. Search the
4604 client first by hash not nickname. Affected file is
4607 * Fixed the silc_client_close_connection to support closing
4608 the client to client connections wihtout deleting too much
4609 data. Affected file lib/silcclient/client.c.
4611 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4612 are received if protocol used to be active but is not anymore
4613 the application would crash due to NULL pointer dereference.
4614 Affected files silcd/server.c and lib/silcclient/client.c.
4616 * Added `hash' field to the SilcClientConnection to include
4617 the hash function negotiated in the SKE protocol.
4619 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4620 to set the channel founder authentication data. A client can
4621 claim the founder rights later by providing the authentication
4622 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4623 This way the channel founder can regain the channel founder
4624 privileges even it is left the channel. This works only on
4625 local server and the client must be connected to the same
4626 server to be able to regain the founder rights. Updated the
4627 protocol specs accordingly.
4629 Added support to the CMODE command in the client to set the
4630 founder auth data. Read the README to see how to set it.
4632 Added support to the CUMODE command to claim the founder
4633 rights. Read the README to see how to do it.
4635 Added support for the founder authentication to the Channel
4636 Entry in the server. Affected file silcd/idlist.h.
4638 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4639 server's CMODE command. Affected file silcd/command.c.
4641 * Added the following new functions into lib/silccore/silcauth.[ch]:
4642 silc_auth_get_method and silc_auth_get_data.
4644 * The server now saves the remote hosts public key to the
4645 SilcIDListData pointer. Affected file silcd/protocol.c.
4647 * The normal server now does not remove the channel entry from
4648 the cache if the founder authentication data is set. It used
4649 to remove it if the founder was the last one on the channel on
4650 the server and left the channel. The auth data is saved and
4651 if the channel is re-joined later the old entry is used with
4652 the old auth data. Affected files silcd/command_reply.c and
4655 * Removed the `pkcs' field from the SilcIDListData structure
4656 in the server; it is not used. Affected file silcd/idlist.h.
4658 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Fixed packet processing on slow links. Partial packets were
4661 never re-processed because the incoming data buffer was cleared
4662 by the application. Application must not directly clear the
4663 sock->inbuf, the packet processing routines handle it. Fixed
4664 this in client library and in server.
4666 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Fixed the WHOIS and IDENTIFY send reply function to really
4669 check whether to send list or just one entry. Affected file
4672 * Cleaned up the LEAVE command's channel key distribution. The
4673 affected file silcd/command.c.
4675 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4676 can enforce the channel mode as well. In that case the ID
4677 includes the ID of the server. The code now enforces the
4678 mode change if the router have different mode than the server.
4680 * The notify client operation with CMODE_CHANGE notify can now
4681 return NULL client_entry pointer if the CMODE was not changed
4682 by client. Application must check for this.
4684 * Added <Server ID> argument to INFO command to support server
4685 info fetching by Server ID.
4687 * Added silc_server_announce_get_channel_users to get assembled
4688 packets of channel users of the specified channel. Affected
4689 file silcd/server.[ch].
4691 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4692 was freed underneath the ID Cache.
4694 * Re-announce clients when the server received CHANNEL_CHANGE
4695 notify from the router. Affected file silcd/packet_send.c.
4697 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4700 crashed since it did not handle the fact that there is no cipher
4701 called "3" and didn't check the error condition. Now fixed.
4703 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4704 flag. It can be used to send message requests.
4706 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Implemented the RESTART command in the client.
4710 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4711 notice type messages. Added notice printing to the user
4714 * The channel keys are not re-generated if the channel's mode
4715 is PRIVKEY, ie private key on the channel exists. Affected
4716 files silcd/server.c and silcd/command.c.
4718 * Fixed a little bug in channel message delivery when channel
4719 private keys are set in the server. Affected file is
4720 silcd/packet_send.c.
4722 * Changed the setting on channel->on_channel = TRUE from the
4723 silc_client_save_channel_key to the JOIN command reply. The
4724 key payload is not received if the private channel key is set.
4725 Affected file lib/silcclient/command_reply.c and the
4726 lib/silcclient/client_channel.c.
4728 * When the CMODE_CHANGE notify is sent and the channel private
4729 key mode is removed the channel key must be re-generated in
4730 other cells as well. Added this support for the router in the
4731 silcd/packet_receive.c.
4733 * Added new local command NOTICE to send notice message on
4734 channel. Affected file silc/local_command.[ch].
4736 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added new local command ME to the client. It is used to send
4739 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4740 some action. Affected file silc/local_command.[ch].
4742 * Changed channel_message and private_message client operations
4743 to deliver the message flags to the application. Added also
4744 the `flags' arguments to the silc_client_send_channel_message
4745 and silc_client_send_private_message functions. Affected file
4748 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Redefined the Private Message Payload to support private message
4751 keys and to support the new private message flags. Updated
4752 the protocol specs. Flags makes it possible to have for example
4753 CTCP style messages.
4755 * Added new type SilcPrivateMessagePayload and defined an API
4756 for it in the lib/silcclient/silcprivate.[ch].
4758 * Tested private message private keys successfully. Tested the
4759 private message key set, unset and list commands with the new
4762 * Redefined the Channel Message Payload to include the channel
4763 message flags (equal with private message flags) to support
4764 for example CTCP style messages.
4766 * Defined some of the message (for channel and private message)
4767 flags. Updated the protocol specs and added the flags to the
4768 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4770 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Added SilcKeyAgreementStatus type to the key agreement routines
4773 to indicate the current status and error if one occured.
4774 The status types are defined in the lib/silcclient/silcapi.h.
4776 * Added new local command KEY that is used to set and unset private
4777 keys for channels, set and unset private keys for private messages
4778 with remote clients and to send key agreement requests and
4779 negotiate the key agreement protocol with remote client. The
4780 key agreement is supported only to negotiate private message keys,
4781 it currently cannot be used to negotiate private keys for channels,
4782 as it is not convenient for that purpose.
4784 * Fixed a minor pending callback setting bug in the function
4785 silc_client_get_client_by_id_resolve, now the function works.
4786 Affected file lib/silcclient/idlist.c.
4788 * Added function silc_net_get_local_port to get local bound
4789 port by socket. Added to lib/silcutil/silcnet.[ch].
4791 * Added `sockets' and `sockets_count' fields to the SilcClient
4792 object. They hold the sockets of the listenning sockets in
4793 the client. Listenning sockets may be for example the key
4794 agreement server. Affected file lib/silcclient/client.[ch].
4795 Added functions the silc_client_add_socket and the
4796 silc_client_del_socket. They are exported to the application
4799 * Added ~./silc/clientkeys to support other client's public keys.
4801 * Renamed verify_server_key client operation to verify_public_key
4802 and added one argument to indicate the type of the connection
4803 (server, client etc.).
4805 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added silc_server_connection_auth_request to handle the
4808 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4809 silcd/packet_receive.[ch].
4811 * Added silc_server_send_connection_auth_request into the
4812 silcd/packet_send.c to send the connection auth request packet.
4814 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4817 * Fixed the public key authentication in responder side in the
4818 server. The `auth_data' pointer includes the SilcPublicKey
4819 not the path to the public key. Affected file silcd/protocol.c.
4821 * Implemented the public key authentication in the initiator side
4822 in the server. Affected file silcd/protocol.c.
4824 * Removed the [RedirectClient] config section from the server
4825 configuration. Is not needed and I don't want to implement it.
4827 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Cleaned up the CMODE command in the server. It now works
4830 correctly and supports all the modes defined in the protocol.
4831 Affected file is silcd/command.c.
4833 * Added `hmac_name' field to the SilcChannelEntry in the server
4834 to hold the default HMAC of the channel. It can be set when
4835 creating the channel (with JOIN command). Affected files
4838 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4839 type to indicate the change of the current cipher and hmac
4840 on the channel. Client can safely ignore the <cipher> argument
4841 (if it chooses to do so) since the CHANNEL_KEY packet will
4842 force the channel key change anyway. The <hmac> argument is
4843 important since the client is responsible of setting the new
4844 HMAC and the hmac key into use.
4846 * Fixed the CMODE command in the client library as well.
4848 * Tested CMODE command in router environment successfully.
4850 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Show the version of the remote client (or server) when connecting
4853 to the server. It is logged to the log file. Affected file
4854 is silcd/protocol.c.
4856 * Fixed the KILLED notify handling in the client library. The
4857 client must be removed from all channels when receiving the
4860 Also, do not remove the client entry when giving the KILL
4861 command but when the KILLED notify is received.
4863 * Removed silc_idlist_find_client_by_nickname from the server.
4864 Not needed anymore. Affected files silcd/idlist.[ch].
4866 * Implemented the CHANNEL_CHANGE notify type handling to the
4867 server. Affected file silcd/server.c.
4871 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Added silc_server_send_notify_invite to send the INVITE
4874 notify between routers.
4876 * Implemented the INVITE command correctly to the server.
4878 * Implemented the INVITE notify type handling in the server.
4880 * Implemented the INVITE command to the client library and on the
4883 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Added function silc_server_get_client_resolve to find the
4886 client entry by ID from all ID lists and then resolve it
4887 (using WHOIS) if it cannot be found. Affected file is
4890 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Implemented the BAN command to the client library.
4894 * The JOIN command in the server now checks the invite list
4897 * Changed the silc_command_reply_payload_encode_va and the
4898 silc_command_payload_encode_va to support that if argument is
4899 NULL it ignores and checks the next argument. Affected file
4900 lib/silccore/silccommand.c.
4902 * Added silc_server_send_notify_ban to send the BAN notify
4903 type between routers.
4905 * Chaned the silc_notify_payload_encode to support that if
4906 argument is NULL it ignores and checks the next argument.
4907 Affected file lib/silccore/silcnotify.c.
4909 * Tested ban lists in router environment successfully.
4911 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Implemented BAN command to the server, in silcd/command.[ch].
4915 * Removed the BAN and INVITE_LIST modes from the CMODE command
4918 * Added function silc_string_match to regex match two strings.
4919 Affected files lib/silcutil/silcutil.[ch].
4921 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Redefined parts of the SilcChannelEntry in the server to support
4924 the new ban and invite lists.
4926 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Redefined the INVITE command. The same command can be used to
4929 invite individuals to the channel but also to manage the invite
4930 list of the channel (to add to and remove from the invite list).
4931 Updated the protocol specs.
4933 * Added new command SILC_COMMAND_BAN that can be used to manage
4934 the ban list of the channel. Updated the protocol specs.
4936 * Removed the channel modes: the SILC_CMODE_BAN and the
4937 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4938 in the CMODE command. The equivalent features are now available
4939 using INVITE and BAN commands. Updated the protocol specs.
4941 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4942 in the network about change in the current ban list. The notify
4943 type is not used by the client.
4945 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4946 support the invite lists.
4948 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Added new function silc_string_regexify that converts string
4951 including wildcard characters into regex string that can
4952 be used by the GNU regex library. Added into the file
4953 lib/silcutil/silcutil.[ch].
4955 Added silc_string_regex_combine to combine to regex strings
4956 into one so that they can be used as one regex string by
4957 the GNU regex library. Added into the file
4958 lib/silcutil/silcutil.[ch].
4960 Added silc_string_regex_match to match two strings. It returns
4961 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4963 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Imported GNU regex to the soruce tree into lib/contrib.
4966 Fixed some compiler warning from the regex.c.
4968 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Fixed MOTD command in the server to work in router environment.
4972 * Fixed the MOTD command in the client library to support
4973 the server argument in the command.
4975 * Added `nickname_len' argument to the silc_idlist_add_client
4976 in the server, as the `nickname' argument may be binary data
4979 * Added silc_idlist_get_channels to return all channels from
4982 * Implemented LIST command to the server. Affected file is
4985 * Implemented the LIST command to the client library and on the
4988 * Added [<user count>] argument to the LIST command reply.
4989 With private channels the user count is not shown.
4991 * Updated TODO and README.
4993 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * The client entry's data.registered must be TRUE even with
4996 global client entry on global client list. The data.registered
4997 is used to check whether the client is anymore in the network,
4998 for example with WHOWAS command so it must be valid.
5000 * Fixed the WHOWAS command in the server. It now actually works
5001 in router environment. Added function into silcd/command_reply.c
5002 silc_server_command_reply_whowas_save.
5004 * Added silc_idlist_purge function to the silcd/idlist.c
5005 to periodically purge the ID Cache.
5007 * Fixed INFO command in the server. It works now in router
5008 environment. Added <server name> argument to the INFO command
5009 reply. Updated the protocol specs.
5011 * Fixed minor bug in silc_idcache_purge to not purge if the
5012 expire value is zero.
5014 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5015 they were buggy because of the WHOWAS information.
5017 * Fixed local command MSG to handle the async resolving of
5018 the remote client properly. It used to fail the first MSG.
5019 Affected file silc/local_command.c.
5021 * Added `data_len' field to SilcIDCache context.
5023 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Update TODO. Todo in commands in the server.
5027 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5030 used by routers as broadcast packet to inform other routers
5031 about the changed user mode.
5033 Implemented the notify handling in the server. Affected file is
5034 silcd/packet_receive.c. Added the function
5035 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5037 * Added new generic Channel Payload and deprecated the New Channel
5038 Payload. The New Channel Payload is now the generic Channel
5041 * Added new argument `mode' to the silc_server_send_new_channel
5042 as it is required in the Channel Payload now.
5044 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5045 and created a new and real SilChannelPayload to represent the
5046 new generic Channel Payload. Implemented the encode/decode
5047 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5049 * Added silc_server_get_client_channel_list to return the list
5050 of channels the client has joined for WHOIS command reply.
5051 Affected file silcd/server.[ch].
5053 * Implemented the channel list sending in the WHOIS command reply
5054 in server and in the client.
5056 Implemented the channel list displaying on the user interface
5057 as well. Affected file silc/client_ops.c.
5059 * Added silc_channel_payload_parse_list to parse list of Channel
5060 Payloads. It returns SilcDList list of SilcChannelPayloads.
5061 Client for example can use this function to parse the list of
5062 channels it receives in the WHOIS command reply. The caller
5063 must free the list by calling silc_channel_payload_list_free.
5064 Affected files lib/silccore/silcchannel.[ch].
5066 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Added one new argument <user mode> to the WHOIS command reply
5069 to return the mode of the user in SILC. Updated the protocol
5072 Implemented it to the server and client.
5074 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Fixed the mode printing on the user interface on joining.
5077 Affected file silc/client_ops.c.
5079 * Implemented the UMODE command and user modes in general to the
5080 client library and to the user interface.
5082 * Implemented the UMODE command to the server.
5084 * The server now sends UNKNOWN_COMMAND error status if client sends
5085 unknown command. Affected file silcd/command.c.
5087 * All server commands now handle the command identifier the right
5088 way when sending the command reply to the client. The client can
5089 use to identify the command replies with the identifier.
5091 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added silc_server_get_client_route to resolve the route to
5094 the client indicated by the client ID. Affected file is
5097 * Added silc_server_relay_packet as general function to relay
5098 packet to arbitrary destination. This deprecates functions
5099 like _send_private_message_key, _relay_notify etc. Affected
5100 file is silcd/packet_send.[ch].
5102 Removed silc_server_send_key_agreement,
5103 silc_server_send_private_message_key and
5104 silc_server_packet_relay_notify functions from the file
5105 silcd/packet_send.[ch].
5109 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5110 server. Affected file silcd/packet_receive.[ch].
5112 * Implemented the KILL command to the client. Implemented the
5113 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5114 Affected files lib/silcclient/command[_reply].c and
5115 lib/silcclient/client_notify.c. Implemented the KILL notify
5116 printing in the user inteface.
5118 * Fixed a lot silc_parse_nick memory leaks from the client
5119 library in the file lib/silcclient/command.c.
5121 * Changed the silc_server_send_notify_on_channels's `sender'
5122 argument from SilcSocketConnection to SilcClientEntry to
5123 check the sender as entry and not as connection object and not
5124 to send to the client provided as argument. The affected file
5125 is silcd/packet_send.[ch].
5127 * The notify packets that are destined directly to the client used
5128 to not to be processed by the server. Now changed that and the
5129 server processes all notify packets. After relaying the packet
5130 to the client the notify packet is processed in the server.
5132 * The silc_server_free_client_data now checks whether there is
5133 pending outgoing traffic for the client and purges the data to
5134 the network before removing the client entry.
5136 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5139 an client is killed from the SILC Network. Updated the protocol
5142 Added new function silc_server_send_notify_killed to the
5143 silcd/packet_send.[ch].
5145 * Added function silc_server_packet_relay_notify to relay notify
5146 packets that are destined directly to a client. In this case
5147 the server does not process the notify packets but merely relays
5148 it to the client. Affected file silcd/packet_send.[ch].
5150 Added also silc_server_packet_process_relay_notify to check
5151 whereto relay the notify. Affected file is
5152 silcd/packet_receive.[ch].
5154 * Implemented the KILL command to the server.
5158 * Added the backup schema desgined last fall to the protocol
5159 specs for everyone to see. The specification is in the
5160 *-spec-xx.txt draft and the packet type definitions for the
5161 backup routers is in *-pp-xx.txt draft. Thusly, added also
5162 new packet type SILC_PACKET_CELL_ROUTERS.
5164 * A big security problem in the implementation discovered. The
5165 signoff of an client did not cause new channel key generation
5166 which it of course should've done. The channel keys must be
5167 always re-generated when client leaves (or signoffs) the channel.
5168 The silc_server_remove_from_channels funtion now handles
5169 the channel key re-generation.
5171 * Added `sender' argument to the silc_server_send_notify_on_channels
5172 to not to send the client provided as argument. Affected file
5173 silcd/packet_send.[ch].
5175 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Implemented OPER and SILCOPER commands into the server and
5180 * Added silc_auth_verify and silc_auth_verify_data to verify
5181 the authentication directly from the authentication payload.
5182 It supports verifying both passphrase and public key based
5183 authentication. Affected file lib/silccore/silcauth.[ch].
5185 * Added `hash' field to the SilcIDListData structure. It is the
5186 hash negotiated in the SKE protocol. Affected file is
5189 * Slight redesigning of the SilcAuthPayload handling routines.
5190 Do not send SilcPKCS but SilcPublicKey as argument.
5192 * Implemented the public key authentication support to the
5193 serverconfig. The public key is loaded from the provided path
5194 and saved as authentication data to void * pointer. Thus,
5195 changed the unsigned char *auth_data to void *auth_data;
5197 * Fixed SHUTDOWN command to send the reply before the server
5198 is shutdown. :) Affected file silcd/command.c.
5200 * Fixed fatal bug in CONNECT command. The hostname was invalid
5201 memory and server crashed. Affected file silcd/command.c.
5203 * Fixed fatal bug in CLOSE command. The server_entry became
5204 invalid but was referenced later in the command. Affected file
5207 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Fixed fatal bug in failure packet handling. Server ignored
5210 the failure and thus crashed when it came.
5214 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5217 that the command may be executed only once in (about) 2 seconds.
5218 The old SILC_CF_LAG flag is same but allows command bursts up
5219 to five before limiting.
5221 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5222 server code. Various commands now includes the CF_LAG_STRICT
5223 flag to disallow any kind of miss-use of the command.
5225 * Fixed the silc_buffer_unformat to not to allocate any data
5226 if the length of the data is zero. It used to allocate the
5227 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5229 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Changed the format of AdminConnection configuration section
5232 in the server. Added username of the admin to the format.
5233 Affected files silcd/serverconfig.[ch].
5235 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5236 to return admin configuration data by host, username and/or
5239 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Implemented WHOWAS command to the server. Added the functions:
5243 silc_server_command_whowas_parse,
5244 silc_server_command_whowas_send_reply,
5245 silc_server_command_whowas_from_client and
5246 silc_server_command_whowas_from_server
5248 * Added <Client ID> argument to the WHOWAS command reply. Updated
5249 the protocol specs accordingly.
5251 * Implemented WHOWAS command and command_reply to the client
5254 Implemented the WHOWAS printing on the user interface.
5256 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added new argument to the WHOWAS command reply, the real name.
5259 It is an optional argument. Updated the protocol specs.
5261 * Added SilcIDCacheDestructor callback that is registered when
5262 the SilcIDCache is allocated. The callback is called when
5263 an cache entry in the ID Cache expires, or is purged from the
5264 cache. Added into lib/silccore/idcache.[ch].
5266 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5267 to destruct the client entries when the cache entry expires.
5268 Other ID Cache's in server and in the client library ignores
5271 * If the ID Cache entry's `expire' field is zero then the entry
5272 never expires. Added boolean `expire' argument to the
5273 silc_idcache_add function in the lib/silccore/idcache.[ch].
5274 If it is TRUE the default expiry value is used.
5276 * Added silc_server_free_client_data_timeout that is registered
5277 when client disconnects. By default for 5 minutes we preserve
5278 the client entry for history - for WHOWAS command.
5280 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Added support to the server to enforce that commands are not
5283 executed more than once in 2 seconds. If server receives
5284 commands from client more frequently, timeout is registered
5285 to process the commands. Affected file silcd/command.c.
5286 Added new function silc_server_command_process_timeout.
5288 * Changed NICK_NOTIFY handling in client library to check that
5289 if the client's nickname was changed, so there is no need to
5290 resolve anything from the server.
5292 * Removed error printing from the WHOIS and IDENTIFY commands.
5293 If error occurs then it is ignored silently in the client library.
5294 The application, however, may map the received error to
5295 human readable error string. The application currently maps
5296 the NO_SUCH_NICKNAME error to string.
5298 * Made the command status message public to the application. Moved
5299 them from lib/silcclient/command_reply.c to
5300 lib/silcclient/command_reply.h. The application can map the
5301 received command status to the string with the
5302 silc_client_command_status_message function.
5304 * Added check to the server to check that client's ID is same
5305 as the Source ID in the packet the client sent. They must
5308 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Added dist-bzip hook to the Makefile.am to make bzip2
5311 compressed distributions.
5313 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Server now enforces the maximum length for the nickname and
5316 the channel as protocol specification dictates. 128 bytes for
5317 nickname and 256 bytes for channel name.
5319 * Moved the WHOIS printing to the application. The client libary
5320 does not print out the WHOIS information anymore, the application
5321 must do it. Renamed silc_client_command_reply_whois_print to
5322 the silc_client_command_reply_whois_save.
5324 The client's idle time is also sent to the application now, and
5325 the idle is shown on screen.
5327 * Added silc_client_command_reply_identify_save to save the
5328 received IDENTIFY entries.
5330 * Do not check for channel private keys in message sending and
5331 reception if the channel does not have the PRIVKEY mode set.
5332 Affected file lib/silclient/client_channel.c.
5334 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5337 just surfaced after chaning the JOIN procedure.
5339 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5341 * Added silc_client_get_clients_by_list to get client entries
5342 from Client ID list, that is returned for example by JOIN
5343 and USERS command replies. The application should use this
5344 function for example when JOIN command reply is received to
5345 resolve the clients already on the channel (library does not
5346 do that anymore as USERS command reply is not used in the JOIN
5347 procedure anymore). Affected files lib/silcclient/silcapi.h and
5348 lib/silcclient/idlist.c.
5350 * JOIN command reply and USERS command reply returns now SilcBuffer
5351 pointers instead of unsigned char pointers when returning
5352 the client list and mode list.
5354 * Added <Client ID> argument to the JOIN command reply, mainly
5355 for the server to identify for which client the command was
5356 originally sent. Updated protocol specs accordingly.
5358 * Added SilcDlist private_key pointer to the SilcChannelEntry
5359 in the client to support the channel private keys. Affected
5360 file is lib/silcclient/idlist.h.
5362 * Added SilcChannelPrivateKey argument to the function
5363 silc_client_send_channel_message so that application can choose
5364 to use specific private ke if it wants to. If it is not provided,
5365 the normal channel key is used, unless private keys are set.
5366 In this case the first (key that was added first) is used
5367 as the encryption key.
5369 * Implemented the support for channel private key handling.
5370 Implemented the following functions:
5372 silc_client_add_channel_private_key,
5373 silc_client_del_channel_private_keys,
5374 silc_client_del_channel_private_key,
5375 silc_client_list_channel_private_keys and
5376 silc_client_free_channel_private_keys
5378 Affected file lib/silcclient/client_channel.c.
5380 * Added the support for the private keys in the channel message
5381 sending and encryption and in the message reception and
5382 decryption. Affected funtions are
5383 silc_client_send_channel_message and silc_client_channel_message.
5385 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Added SKE's key verify callback to the client library's
5388 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5390 * Removed the statement that server (or router) must send USERS
5391 command reply when joining to the channel so that the client
5392 knows who are on the channel. Instead, the client list and
5393 client's mode list is now sent in the JOIN command reply to the
5394 client who joined channel. This is better solution.
5396 * Added function silc_server_get_users_on_channel and function
5397 silc_server_save_users_on_channel to the silcd/server.[ch].
5399 * Removed function silc_server_command_send_users from the
5402 * Do not show topic on the client library anymore. The topic is
5403 sent in the command reply notify to the application and the
5404 application must show the topic now.
5406 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Added client searching by nickname hash into the IDENTIFY and
5409 WHOIS commands in the server as they were clearly missing from
5410 them. Affected file is silcd/command.c.
5412 * Fixed a bug in private message receiving in the client library.
5413 The remote ID was freed and it wasn't supposed, now it is
5416 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Minor fix to the channel payload; allocate the data area, as it
5419 needs to be of specific length.
5421 * If the key agreement port is zero then the operating
5422 system will define the bound port. Affected files are
5423 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5425 * Added new function silc_channel_payload_decrypt into the file
5426 lib/silccore/silcchannel.[ch].
5428 * Moved the channel message etc, check from silc_packet_decrypt
5429 to applications. The library calls now a generic
5430 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5431 when the packet is either normal or special. This was done to
5432 allow more wide range of checking that was not allowed when
5433 the code was in library. Now applications can do virtually any
5434 checks to the packet and return to the library the decision how
5435 the packet should be processed. Affected files are
5436 lib/silccore/silcpacket.[ch].
5438 Added silc_server_packet_decrypt_check to the server and
5439 silc_client_packet_decrypt_check to the client library.
5441 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5442 to send with specified source and destination information.
5444 * Channel message delivery between routers was broken after the
5445 channel key distribution was fixed earlier. The channel key
5446 was used be to distributed to other routers as well which is not
5447 allowed by the protocol. Now this is fixed and channel keys
5448 really are cell specific and the channel message delivery between
5449 routers comply with the protocol specification.
5451 * Fixed various commands in server to check also the global list
5452 for the channel entry and not just the local list. The affected
5453 file silcd/command.c.
5455 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added assert()s to buffer formatting and unformatting routines
5458 to assert (if --enable-debug) when error occurs. Affected
5459 file: lib/silcutil/silcbuffmt.c.
5461 * Changed to auto-reconnect to check whether the remote host is
5462 router and register the re-connect timeout if it is. It used
5463 to check that whether we are normal server, but router must do
5464 auto-reconnect with another router as well. Affected file
5467 * Removed the [<key len>] option from CMODE command as the cipher
5468 name decides the key length, nowadays. See the defined ciphers
5469 from the protocol specification.
5471 * Added [<hmac>] option to the CMODE command to define the HMAC
5472 for the channel. Added SILC_CMODE_HMAC channel mode.
5474 * Added [<hmac>] option for the JOIN command so that user can
5475 select which HMAC is used to compute the MACs of the channel
5478 * Added Hmac field to the Channel Message Payload. The integrity
5479 of plaintext channel messages are now protected by computing
5480 MAC of the message and attaching the MAC to the payload. The
5481 MAC is encrypted. Now, it is clear that this causes some
5482 overhead to the size of the packet but rationale for this is that
5483 now the receiver can verify whether the channel message decrypted
5484 correctly and also when private keys are set for the channel the
5485 receiver can decrypt the packet with several keys and check from
5486 the MAC which key decrypted the message correctly.
5488 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5489 lib/silccrypt/silccipher.[ch].
5491 * Added silc_hash_len to return the digest length into the
5492 lib/silcrypt/silchash.[ch].
5494 * Rewrote parts of Silc Channel Payload interface in the
5495 lib/silccore/silcchannel.[ch]. The encode function now also
5496 encrypts the packet and parse function decrypts it.
5498 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Fixed a minor formatting bug in the SKE's key material processing.
5501 It actually might have processed the keys wrong way resulting
5504 * Redefined the mandatory HMAC algorithms and added new algorithms.
5505 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5506 and hmac-md5 truncated to 96 bits. The mandatory is now
5507 hmac-sha1-96. Rest are optional (including the one that used
5508 to be mandatory). Rationale for this is that the truncated HMAC
5509 length is sufficient from security point of view and can actually
5510 make the attack against the HMAC harder. Also, the truncated
5511 HMAC causes less overhead to the packets. See the RFC2104 for
5514 * Added new [hmac] configuration section. The SKE used to use
5515 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5516 is of course wrong. The official names that must be proposed in
5517 the SKE are the ones defined in the protocol specification
5518 (hmac-sha1-96 for example). The user can configure any hmac
5519 using any hash function configured in the [hash] section. At
5520 least, the mandatory must be configured.
5522 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5524 * Added HMAC list to the SKE proposal list. It has now both
5525 hash algorithm list and HMAC list. This makes the protocol
5526 incompatible with previous versions. The SKE now seems to work
5527 the way it is supposed to work, for the first time actually.
5529 * Defined plain Hash algorithms to the protocol specification.
5532 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Implemented support for key agreement packets into the server.
5535 Added functions silc_server_key_agreement and
5536 silc_server_send_key_agreement. Other than these functions,
5537 server has nothing to do with this packet.
5539 * Added support for private message key packets into the server.
5540 Added functions silc_server_private_message_key and
5541 silc_server_send_private_message_key.
5545 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5546 called in the protocol's final callback instead in the END
5547 protocol state. This makes a little more sense and in the same
5548 time in client we can use the same protocol routines for normal
5549 key exchange and to key agreement packet handling as well.
5551 * Added to both client's and server's KE protocol context the
5552 SilcSKEKeyMaterial pointer to save the key material. We will
5553 bring the key material to the protocol's final callback by doing
5554 this. The final callback must free the key material.
5556 * Added SKE's packet_send callback into client's KE protocol
5557 context so that the caller can choose what packet sending function
5558 is used. This way we can use different packet sending when
5559 doing normal SKE when doing key agreement packet handling (in
5560 the key agreement packet handling we do not want to encrypt
5563 * Implemented the responder side of the key agreement routines
5564 in the client. The client can now bind to specified port and
5565 accept incoming key negotiation. The key material is passed
5566 to the application after the protocol is over.
5568 * Implemented the processing of incoming Key Agreement packet
5569 in the client. Added function silc_client_key_agreement to
5572 * Implemented the intiator side of the key agreement routines
5573 in the client. The client can now initiate key agreement with
5574 another remote client. The key material is passed to the
5575 application after the protocol is over.
5577 * Created client_keyagr.c to include all the key agreement
5580 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5581 SILC_TASK_CALLBACK except that it is not static.
5583 * Created client_notify.c and moved the Notify packet handling
5584 from the client.[ch] into that file.
5586 * Created client_prvmsg.c and moved all private message and
5587 private message key routines from the client.[ch] into that file.
5589 * Create client_channel.c and moved all channel message and
5590 channel private key routines from the client.[ch] into that file.
5592 * Changed silc_client_get_client_by_id_resolve to resolve with
5593 WHOIS command instead of IDENTIFY command, in the file
5594 lib/silclient/idlist.c.
5596 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Implemented the SKE's responder side to the Client library.
5600 * When FAILURE is received to the protocol do not trust it
5601 blindly. Register a timeout to wait whether the remote closes
5602 the connection as it should do it, only after that process the
5603 actual failure. This was changed to both client and server.
5605 * Added client_internal.h to include some of the structures
5606 there instead of client.h in lib/silcclient/.
5608 * Added function silc_task_unregister_by_callback to unregister
5609 timeouts by the callback function.
5611 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Some "Incomplete WHOIS info" errors has been appearing on the
5614 log files. Took away the entry->userinfo check from WHOIS
5615 reply sending. The entry->userinfo is now " " if client did not
5616 provide one. I thought this was fixed earlier but something
5617 is wrong still. Let's see if the error still appears.
5619 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Fixed a minor bug in the login when the channel key is
5622 re-generated in the server. It used to generate the key in
5623 wrong order and thus caused problems in the channel traffic.
5625 * Fixed a minor bug in channel key distsribution after
5626 KICK command. The key was not sent to the router even though
5629 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Added silc_ske_process_key_material_data as generic routine
5632 to process any key material as the SILC protocol dictates. The
5633 function is used by the actual SKE library but can be used by
5634 applications as well. This relates to the private message keys
5635 and the channel private keys since they must be processed the
5636 same way the normal SILC session keys. The protocol dictates
5637 this. Affected files: lib/silcske/silcske.[ch].
5639 Added also silc_ske_free_key_material to free the
5640 SilcSKEKeyMaterial structure.
5642 * Defined silc_cipher_set_key function to set the key for
5643 cipher without using the object's method function. The affected
5644 files: lib/silccrypt/silccipher.[ch].
5646 * Implemented silc silc_client_add_private_message_key,
5647 silc_client_add_private_message_key_ske,
5648 silc_client_del_private_message_key,
5649 silc_client_list_private_message_keys and
5650 silc_client_free_private_message_keys functions in the
5653 Added functions silc_client_send_private_message_key to send
5654 the Private Message Key payload and silc_client_private_message_key
5655 to handle incoming Private Message Key payload.
5657 * Added Cipher field to the Private Message Key payload to set
5658 the cipher to be used. If ignored, the default cipher defined
5659 in the SILC protocol (aes-256-cbc) is used.
5661 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Removed lib/silcclient/ops.h file.
5665 Redefined parts of the SILC Client Library API. Created new
5666 file silcapi.h that deprecates the ops.h file and defines the
5667 published Client Library API. Defined also private message key
5668 API and channel private key API into the file.
5670 This is the file that the application must include from the
5671 SILC Client Library. Other files need not be included by
5672 the application anymore.
5674 * Added new key_agreement client operation callback and also
5675 defined the Key Agreement library API for the application.
5677 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5680 is used by clients to request key negotiation between another
5681 client in the SILC network. If the negotiation is started it
5682 is performed using the SKE protocol. The result of the
5683 negotiation, the secret key material, can be used for example
5684 as private message key.
5686 Implemented the Key Agreement payload into the files
5687 lib/silccore/silauth.[ch].
5689 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Redefined ciphers for the SILC protocol. Added some new ciphers
5692 and defined the key lengths for the algorithms. Changed the
5693 code accordingly. The default key length is now 256 bits.
5695 * Fixed SKE key distribution function silc_ske_process_key_material
5696 when the key length is more than 128 bits. The default key
5697 length in SILC is now 256 bits.
5699 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5700 to indicate unsupported algorithm.
5702 * Renamed rijndael.c to aes.c and all functions as well.
5704 * Fixed a long standing channel key setting bug in client library.
5705 Weird that it has never surfaced before.
5707 * Fixed bug in channel deletion. If the entire channel is removed
5708 then it must also delete the references of the channel entry
5709 from the client's channel list as the client's channel entry and
5710 the channel's client entry share same memory.
5712 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Implemented CONNECT and SHUTDOWN commands in the client.
5716 * Implemented CLOSE command to the client.
5718 * Added the function silc_idlist_find_server_by_name into the
5719 files silcd/idlist.[ch].
5721 Added the function silc_idlist_find_server_by_conn into the
5722 files silcd/idlist.[ch].
5724 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * DIE command was renamed to SHUTDOWN. Updated the both code
5729 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5730 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5732 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5735 * Added function silc_server_create_connection function to create
5736 connection to remote router. My server implementation actually
5737 does not allow router to connect to normal server (it expects
5738 that normal server always initiates the connection to the router)
5739 so the CONNECT command is only good for connecting to another
5742 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5745 or some other client was kicked from the channel.
5747 Implemented the handling of the notify type to both client
5750 Implemented silc_server_send_notify_kicked to send the KICKED
5751 notify. It is used to send it to the server's primary router.
5753 * Implemented the KICK command into server and client.
5755 * Added `query' argument to the silc_idlist_get_client function
5756 to indicate whether to query the client from server or not if
5759 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5760 to indicate that the client is not channel founder.
5764 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Removed the rng context from SilcPacketContext structure and
5767 changed that the packet routine uses the Global RNG API.
5769 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added support for quit message that client can "leave" on the
5772 channel when it quits the SILC. It is ditributed inside the
5773 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5775 Added silc_server_free_client_data that will take the
5776 signoff message as argument.
5778 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5780 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Updated parts of the protocol specification to keep it up
5785 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5788 payloads in one packet.
5790 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5791 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5792 use now the new List flag.
5794 * Also deprecated the following packet types: REPLACE_ID,
5795 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5797 * Added list support for Notify packet in server.
5799 * Added silc_server_send_notify_channel_change to send the
5800 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5801 the silc_server_send_replace_id.
5803 * Added silc_server_send_notify_nick_change to send the
5804 NICK_CHANGE notify type. Deprecates the function
5805 silc_server_send_replace_id.
5807 * Added silc_server_send_notify_join to send the JOIN notify type.
5808 Deprecates the function silc_server_send_new_channel_user.
5810 * Added silc_server_send_notify_leave to send LEAVE notify type.
5811 Deprecates the function silc_server_send_remove_channel_user.
5813 * Added silc_server_send_notify_cmode and
5814 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5815 types. Deprecates the silc_server_send_set_mode function.
5817 * Added SERVER_SIGNOFF notify type to indicate that server has
5818 quit. This means that all clients on the channel from that
5819 server will drop. This can be also used when netsplit happens.
5821 Deprecated REMOVE_ID packet type since it is not needed anymore
5824 Added silc_server_send_notify_server_signoff to send the
5825 SERVER_SIGNOFF notify type. Deprecates the function
5826 silc_server_send_remove_id.
5828 Added also silc_server_send_notify_signoff to send the
5829 SIGNOFF notify type.
5831 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5832 SILC protocol from this day on. Changed the protocol
5833 specification as well.
5835 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5836 notify type. It is used between routers to notify about
5837 topic changes on a channel.
5839 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5842 * Partly updated the protocol specification to comply with the
5843 changes now made. It is still though a bit outdated.
5845 * The JOIN notify type now takes one extra argument <Channel ID>.
5846 The packet used to be destined to the channel but now the
5847 JOIN type may be sent as list thus it is impossible to
5848 destine it to any specific channel. By adding this argument
5849 it is again possible.
5851 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Added CREDITS file. The CHANGES and CREDITS file will appear
5854 in the distribution as well.
5856 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5859 types in the server's silcd/packet_receive.c.
5861 * Implemented CMODE and CUMODE to work in router environment.
5863 * Fixed minor encoding and decoding buglet from the
5864 lib/silccore/silcmode.c.
5866 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5869 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5871 * Changed all SilcConfigServer* and silc_config_server* to
5872 SilcServerConfig* and silc_server_config*, respectively.
5875 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Associated the ID (client or server ID) to the Authentication
5878 Payload to avoid any possibility of forging. Updated the
5879 protocol specification and the code accordingly.
5881 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * The RSA key length is now save to the RsaKey context in the
5884 key generation process in lib/silccrypt/rsa.c. The key length
5885 is now used to figure out the maximum size of the block allowed
5886 to be encrypted/signed.
5888 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5889 is equivalent to the silc_mp_mp2bin but does not allocate any
5892 * Changed silc_mp_mp2bin API to take length argument. If it is
5893 non-zero then the buffer is allocated that large. If zero, then
5894 the size is approximated using silc_mp_sizeinbase, which however
5897 * Created Global RNG API which is global RNG that application can
5898 initialize. After initializing, any routine anywhere in the
5899 code (including library) can use RNG without allocating a new
5900 RNG object. This was done to allow this sort of use of the
5901 RNG in code that has no chance to allocate RNG object. All
5902 applications currently allocate this and many routines in the
5903 library use this. Affected file lib/silccrypt/silcrng.[ch].
5905 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5906 it to use the Global RNG API.
5908 * Defined Authentication Payload into protocol specification that
5909 is used during SILC session to authenticate entities. It is
5910 used for example by client to authenticate itself to the server
5911 to obtain server operator privileges.
5913 Implemented this payload into the lib/silccore/silcauth.[ch].
5914 Implemented also routines for public key based authentication
5915 as the new protocol specification dictates.
5917 Moved definitions of different authentication methods from
5918 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5920 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5921 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5922 silc_pkcs_verify_with_hash functions into the file
5923 lib/silccrypt/silcpkcs.[ch].
5925 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * The client entry's userinfo pointer must be always valid.
5928 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5929 will fail since it requires the userinfo. Now, the userinfo
5930 is allocated as "" if actual userinfo does not exist. Actually,
5931 it must exist and it is totally Ok to drop client connections
5932 that does not announce the userinfo. However, we will make
5933 this workaround for now.
5935 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5936 to return the remote port by socket.
5938 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5941 SILC_SERVER_PENDING_EXEC and added an new macro
5942 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5943 data or when error occurs while processing the pending command.
5945 Added new argument `destructor' into silc_server_command_pending
5946 and to the SilcServerCommandPending object. This destructor is
5947 now called after calling the pending callback or if error occurs
5948 immediately. If error occurs the actual pending callback won't
5949 be called at all - only the destructor. The destructor may be
5950 NULL if destructor is not needed.
5952 All this applies for client library code as well. Similar
5953 changes were made there as well for the pending commands.
5955 In the client, the application must now allocate the
5956 SilcClientCommandContext with the silc_client_command_alloc
5959 * Added reference counter to the SilcServerCommandContext. Added
5960 function silc_server_command_alloc and silc_server_command_dup
5963 Same type of functions added to the client library for the same
5966 * Removed the cmd_ident from IDListData away since it is now
5967 global for all connections. It is the command identifier used
5968 in command sending and with pending commands. The affected file
5971 * Added reference counter to the SilcSocketConnection objecet to
5972 indicate the usage count of the object. The object won't be
5973 freed untill the reference counter hits zero. Currently only
5974 server uses this, and client ignores it. The client must be
5975 set to use this too later. The affected files are
5976 lib/silccore/silcsockconn.[ch]. Added also the function
5977 silc_socket_dup to increase the reference counter.
5979 This was mainly added because it is possible that the socket
5980 is removed underneath of pending command or other async
5981 operation. Now it won't be free'd and proper DISCONNECTING
5982 flags, etc. can be set to avoid sending data to connection that
5983 is not valid anymore.
5985 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5986 the connection. After that it sets SILC_SET_DISCONNECTED.
5987 It is, however, possible that the socket data is not still freed.
5988 The silc_server_packet_process now checks that data is not
5989 read or written to connection that is DISCONNECTED. The socket
5990 get's freed when the reference counter hits zero.
5992 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Changed the client operation API: channel_message operation's
5995 `sender' is now the client entry of the sender, not the nickname
5996 and the `channel' is the channel entry, not the channel name.
5998 In the private_message operation the `sender' is now also the
5999 client entry of the sender not the nickname.
6001 Affected file is lib/silcclient/ops.h and all applications
6002 using the client operations.
6004 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6006 * Moved the calling of ops->connect() from connect_to_server_final
6007 into receive_new_id functin since that is the point when the
6008 client is actually allowed to send traffic to network. The
6009 affected file is lib/silcclient/client.c.
6011 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6014 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6015 (if needs broadcasting) instead of broadcasting the packets one
6016 by one which would make a burst in the network traffic.
6018 * Added `broadcast' argument to the functions in silcd/server.[ch]
6019 silc_server_create_new_channel[_with_id] to indicate whether
6020 to send New Channel packet to primary router.
6022 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6024 * Added new function into the silcd/server.[ch] files:
6025 silc_server_create_new_channel_with_id to create new channel with
6026 already existing Channel ID.
6028 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6029 lib/silccore/silcpacket.h. This packet is used t send list of
6030 Set Mode payloads inside one packet. Server uses this to set
6031 the modes for the channels and clients on those channels, that it
6032 announced to the router when it connected to it. The protocol
6033 specification has been updated accordingly.
6035 * The silc_server_new_channel did not handle the packet coming
6036 from normal server as it normally does not send that. However,
6037 when it announces its channels it does send it. Implemented
6038 the support for that.
6040 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6041 into the file lib/silccore/id.h.
6043 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Fixed memory leaks in the functions silc_idlist_del_client,
6046 silc_idlist_del_channel and silc_idlist_del_server in the file
6047 silcd/idlist.c. All of those leaked like a sieve.
6049 * Fixed some small memory leaks in the client's function
6050 silc_client_notify_by_server.
6052 * Added functions into silcd/server.c: silc_server_announce_clients,
6053 silc_server_announce_channels and silc_server_announce_server.
6054 These functions are used by normal and router server to announce
6055 to its primary router about clients, channels and servers (when
6056 router) that we own. This is done after we've connected to the
6059 These functions effectively implements the following packet types:
6060 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6061 and SILC_PACKET_NEW_ID_LIST.
6063 * Added new functions into the silcd/packet_receive.[ch]:
6064 silc_server_new_id_list, silc_server_new_channel_list and
6065 silc_server_new_channel_user_list to handle the incoming
6066 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6068 * Added support of changing Channel ID in the function
6069 silc_server_replace_id. If the server that announces a channel
6070 to the router already exists in the router (with same name but
6071 with different Channel ID), router is responsible to send
6072 Replace ID packet to the server and force the server to change
6073 the Channel ID to the one router has.
6075 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6076 client that the Channel ID has been changed by the router. The
6077 normal server sends this to the client. Client must start using
6078 the new Channel ID as the channel's ID.
6080 Implemented handling of this new type into lib/silcclient/client.c
6081 into the function silc_client_notify_by_server.
6083 * Added new function silc_idlist_replace_channel_id into the files
6084 silcd/idlist.[ch] to replace the Channel ID.
6086 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Call silc_server_command_identify_check always when processing
6089 the IDENTIFY command in silcd/command.c
6091 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6094 send keepalive packets. The packet can be sent by clients,
6095 servers and routers.
6097 Added function silc_socket_set_heartbeat into the file
6098 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6099 If not set, the heartbeat is not performed. The actual
6100 heartbeat is implemented in the low level socket connection
6101 library. However, application is responsible of actually
6104 Added silc_server_send_heartbeat to send the actual heartbeat
6105 packet into silcd/packet_send.[ch]. Server now performs
6106 keepalive with all connections.
6108 * Added silc_task_get_first function into lib/silcutil/silctask.c
6109 to return the timeout task with shortest timeout. There was a bug
6110 in task unregistration that caused problems. TODO has been
6111 updated to include that task system must be rewritten.
6113 * The client library will now resolve the client information when
6114 receiving JOIN notify from server for client that we know but
6115 have incomplete information.
6117 * Rewrote parts of silc_server_remove_from_channels and
6118 silc_server_remove_from_one_channel as they did not remove the
6119 channel in some circumstances even though they should've.
6121 * Encryption problem encountered in server:
6123 The LEAVE command used to send the Channel Key packet to the
6124 router immediately after generating it. However, the code
6125 had earlier sent Remove Channel user packet but not immediately,
6126 ie. it was put to queue. The order of packets in the router
6127 was that Channel Key packet was first and Remove Channel User
6128 packet was second, even though they were encrypted in the
6129 reverse order. For this reason, MAC check failed. Now, this
6130 is fixed by not sending the Channel Key packet immediately but
6131 putting it to queue. However, this is more fundamental problem:
6132 packets that are in queue should actually not be encrypted
6133 because packets that are sent immediately gets encrypted
6134 actually with wrong IV (and thus MAC check fails). So, packets
6135 that are in queue should be encrypted when they are sent to
6136 the wire and not when they put to the queue.
6138 However, the problem is that the current system has not been
6139 designed to work that way. Instead, the packet is encrypted
6140 as soon as possible and left to the queue. The queue is then
6141 just purged into wire. There won't be any fixes for this
6142 any time soon. So, the current semantic for packet sending
6145 o If you send packet to remote host and do not force the send
6146 (the packet will be in queue) then all subsequent packets to the
6147 same remote host must also be put to the queue. Only after the
6148 queue has been purged is it safe again to force the packet
6151 o If you send all packets immediately then it safe to send
6152 any of subsequent packets through the queue, however, after
6153 the first packet is put to queue then any subsequent packets
6154 must also be put to the queue.
6156 Follow these rules and everything works fine.
6158 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Added new function silc_server_remove_clients_by_server to
6161 remove all client entries from ID list when the server connection
6162 is lost. In this case it is also important to invalidate all
6163 client entires as they hold the invalid server entry. This
6164 fixes fatal bug when server has lost connection and will reconnect
6167 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Made some sanity checks to silc_server_daemonise like to check
6170 whether the requested user and group actually exists.
6172 * Added sanity check to SKE's silc_ske_responder_finish to check
6173 that the public and private key actually is valid.
6175 * Invalidate the client's nickname when receiving Replace ID
6176 packet and the Client ID is being replaced. This means that the
6177 server will query the nickname if someone needs it (client)
6180 * Sort the ID Cache in client library when the ID Cache data
6181 has changed (needs sorting).
6183 * Do not allow for SILC client to create several connections to
6184 several servers. The client does not support windows right now
6185 and generating multiple connections causes weird behaviour.
6187 Irssi-silc client does support windows and can handle several
6188 connections without problems, see: www.irssi.org and SILC plugin.
6190 * Fixed some places where client was added to the IDList. The
6191 rule of thumb is following (in order to get everything right):
6192 If the client is directly connected local client then the
6193 `connection' argument must be set and `router' argument must be
6194 NULL to silc_idlist_add_client function. If the client is not
6195 directly connected client then the `router' argument must
6196 bet set and the `connection' argument must be NULL to the
6197 silc_idlist_add_client function.
6199 * The funtion silc_server_packet_send_local_channel actually did
6200 not check whether the client was locally connected or not. It
6201 does that now. Fixed a bug related to LEAVE command.
6203 * Fixed Remove Channel User payload parsing bug in server's
6204 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6206 * The server's silc_server_save_channel_key now checks also the
6207 global ID list for the channel as it might not be in the local
6208 list. Fixed a bug related to LEAVE command.
6210 * Is this the end of the [<unknown>] buglet that has been lurking
6211 around for a long time? A little for loop fix in server's
6212 silc_server_command_whois_parse that is used by both IDENTIFY
6213 and WHOIS command. At least, this was a clear bug and a cause
6214 of one type of [<unknown>] buglet.
6216 * WHOIS and IDENTIFY commands call the function
6217 silc_server_command_[whois/identify]_check function even if
6218 we are not router server.
6220 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Added --with-gmp configuration option. If set the GMP
6223 is always compiled in the SILC source tree. If not set then
6224 it is checked whether the system has the GMP3 installed. If
6225 it has then the GMP won't be compiled (the system's headers
6226 and library is used), if it doesn't have it then the GMP is
6227 compiled in the SILC source tree.
6229 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Changed RSA private exponent generation to what PKCS #1
6232 suggests. We try to find the smallest possible d by doing
6233 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6234 not security fix but optimization.
6236 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Added new config entry [Identity] to fork the server and run
6239 it as specific user and group. A patch from Bostik.
6241 * Imported Dotconf configuration library into lib/dotconf.
6242 This will be used to create the SILC configuration files later.
6243 It will appear in the distsribution after this commit.
6245 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * A big code auditing weekend happening. Auditing code for
6248 obvious mistakes, bugs and errors. Also, removing any code
6251 Removed files for being obsolete:
6253 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6254 inline in the file lib/silcutil/silcbuffer.h)
6256 o lib/silcutil/silcbufutil.c (the header has inline versions)
6258 Changed code to fix possible error conditions:
6260 o The buffer formatting routines now check that the destination
6261 buffer really has enough space to add the data. This applies for
6262 both buffer formatting and unformatting
6263 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6264 unformatting was changed to accomodate following rules:
6265 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6266 sent to the function while XXX_*STRING will not allocate or copy
6267 the data into the buffer. Instead it sets the pointer from the
6268 buffer into the pointer sent as argument (XXX_*STRING used to
6269 require that the pointer must be allocated already). This change
6270 makes this whole thing a bit more consistent and more optimized
6271 (note that the data returned in the unformatting with XXX_*STRING
6272 must not be freed now). The routines return now -1 on error.
6274 o Tried to find all code that use buffer_format and buffer_unformat
6275 and added return value checking to prevent formatting and
6276 especially unformatting errors and possible subsequent fatal
6279 o Changed ske->x and ske->KEY to mallocated pointers in
6280 lib/silcske/silcske.h. Fixed possible data and memory leak.
6282 o Added return value checking to all *_parse* functions. Fixed
6283 many memory leaks as well.
6285 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6286 so that buffer overflows would not happen. All code now also
6287 checks the return value as it can fail.
6289 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Added reconnection support to server if the normal server looses
6292 its connection to the router (for example if router is rebooted).
6293 The server performs normal reconnection strategy implemented
6294 to the server. Affected file silcd/server.c.
6296 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added new packet type SILC_PACKET_SET_MODE that is used to
6299 distribute the information about changed modes (for clients,
6300 channels and clients channel modes) to all routers in the
6301 network. Updated the protocol specification accordingly.
6303 Added functions into silcd/packet_send.c and
6304 silcd/packet_receive.c: silc_server_send_set_mode,
6305 silc_server_set_mode.
6307 Added new files silcmode.[ch] into lib/silccore that implements
6308 the encoding and decoding of Set Mode Payload. Added new type
6309 SilcSetModePayload. Moved the definitions of different modes
6310 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6312 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Oops, a little mistake in server's connection authentication
6315 protocol. The protocol is not ended with FAILURE but with
6316 SUCCESS if the authentication is Ok. :) Affected file is
6319 * Implemented NICK_CHANGE notify handling in server in the file
6320 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6321 the local clients on the channel. After the changing nickname
6322 in router environment snhould work and the [<unknown>] nickname
6323 should appear no more.
6325 The silc_server_replace_id function that receives the Replace ID
6326 payload now sends the NICK_CHANGE notify type also in the file
6327 silcd/packet_receive.c
6329 * Changed WHOIS and IDENTIFY command to support the maximum amount
6330 of arguments defined in protocol specs (3328 arguments). This
6331 fixed a bug that caused problems when there were more than three
6334 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Added extra parameter, command identifier, to the
6337 silc_client_send_command so that explicit command identifier
6340 Changed that ID list routines uses specific command identifier
6341 when sending WHOIS/IDENTIFY requests to the server so that they
6342 can be identified when the reply comes back.
6344 Affected files lib/silcclient/command.[ch],
6345 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6347 * Added `sender' argument to silc_server_packet_send_to_channel
6348 to indicaet the sender who originally sent the packet to us
6349 that we are now re-sending. Ignored if NULL. Affected file
6350 silcd/packet_send.[ch].
6352 * Added some server statistics support in silcd/server_internal.h
6353 SilcServerStatistics structure and around the server code. Also
6354 send some nice statistics information when client is connecting
6357 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Fixed channel ID decoding in server's JOIN command reply in
6360 silcd/command_reply.c
6362 * Fixed braodcasting of replace ID payload to not to send it if
6363 we are standalone server in silcd/packet_receive.c.
6365 * Fixed all channel message sending routines to not to send
6366 packets to clients that has router set, since they are routed
6367 separately in the same function earlier. Affects file
6368 silcd/packet_send.c and all channel packet sending functions.
6370 * In USERS reply, res_argv[i] are not allocated, the table
6371 is allocated. Thus changed that free the table, not its
6374 * In server's whois_check and identify_check if the client is
6375 locally connected do not send any WHOIS commands - they are not
6378 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Fixed some minor bugs in client when sending WHOIS command. The
6381 arguments was in wrong order.
6383 * Removed statis function add_to_channel from server in
6384 silcd/command.c that was previously used with the joining but
6387 * Tested USERS command in router environment successfully with two
6388 routers, two servers and two clients.
6390 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Reorganized the USERS command and command reply in client library
6393 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6394 When the command is given by user we register a pending command
6395 callback that will reprocess the command after the reply has been
6396 received from the server. When reprocessing the packet we then
6397 display the information. Thus, the USERS information is displayed
6398 now in the command callback instead of in the command reply
6399 callback. The processing of the command is same as previously
6400 when server has sent the command reply in the JOINing process.
6402 * Added to USERS command in silcd/command_reply.c to join the client,
6403 we didn't use to know about, to the channel after we've created
6404 a client entry for it. Also, for clienet we did know already still
6405 check whether it is on the channel or not and add it if not.
6407 * Removed silc_server_command_join_notify as the function and its
6410 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Changed the client's pending command handling to the same as the
6413 server's pending command handling. It is also now possible to
6414 execute command reply functions from other command reply
6415 function as the function callbacks for commands and command
6416 replies are one and same. The pending commands are not static
6417 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6418 in client connection context. Thus, pending commands are server
6419 connection specific as it is convenient.
6421 Changed the function silc_client_command_pending and
6422 silc_client_command_pending_del and added new function
6423 silc_client_command_pending_check. Removed the
6424 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6427 * Added cmd_ident, current command identifier, to the client
6428 connection context in lib/silcclient/client.h to keep track on
6429 command identifiers used in command sending. Client's command reply
6430 function handling now supports the mandatory command identifiers.
6432 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6433 funtions in client to fully support pending command callbacks.
6435 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6436 as one of the arguments to the application in the command reply
6439 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6440 before first releasing SILC but came back. Now it is removed again
6441 and should come back nomore. The FORWARDED flag was used only
6442 by the JOINing procedure by forwarding the command packet to router.
6443 Now, the JOINing procedure has been changed to more generic (due
6444 to various router environment issues) and FORWARDED is not needed
6445 anymore for anything. The protocol specification is yet to be
6448 Now, removed silc_server_packet_forward from server and the flag
6449 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6451 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Renamed NAMES command to USERS command. The NAMES was named that
6454 due to historical reasons. Now it is renamed. Also, rewrote
6455 parts of the USERS command. The nickname list is not sent anymore
6456 by the server. Only Client ID and mode lists are sent in the USERS
6457 command. Changed this also to the protocol specification.
6459 The client now resolves the names and stuff after it receives
6460 the USERS list from the server when joining to the channel.
6462 * WHOIS and IDENTIFY commands has been changed to support multiple
6463 Client ID's per command. One can now search for multiple users
6464 in the network by sending only one WHOIS or IDENTIFY command.
6465 Changed the code and the protocol specifications.
6467 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6468 uses silc_server_command_whois_parse to parse the request. */
6470 * If normal server, do not parse the WHOIS and IDENTIFY requests
6471 before sending it to the router. Saves some time.
6473 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Fixed JOIN command on client library. Wrong number of arguments
6476 used to crash the client.
6478 * Added silc_server_channel_has_global function to check whether
6479 channel has global users or not.
6481 * Added silc_server_channel_has_local function to check whether channel
6482 has locally connected clients on the channel.
6484 * The silc_server_remove_from_one_channel now checks whether the
6485 channel has global users or not after given client was removed from
6486 the channel. It also checks whether the channel has local clients
6487 on the channel anymore. If it does not have then the channel entry
6488 is removed as it is not needed anymore.
6490 * The silc_server_notify now checks on JOIN notify whether the joining
6491 client is one of locally connected or global. If it is global then
6492 the channel has now global users on the channel and that is marked
6493 to the channel entry. Also, it now saves the global client to
6494 global list who is joining and JOINs it to the channel. This is
6495 for normal server, that is.
6497 Changed silc_server_send_notify_on_channel,
6498 silc_server_packet_relay_to_channel and
6499 silc_server_packet_send_to_channel check if we are normal server
6500 and client has router set (ie. global client) do not send the
6501 message to that client, as it is already routed to our router.
6503 * Implemented LEAVE notify type handling in silc_server_notify
6506 * Tested LEAVE command in router environment successfully. Tested
6507 with two routers, two servers and two clients.
6511 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6513 * Implemented SIGNOFF notify type handling in silc_server_notify
6516 * silc_server_remove_id now removes the client entry from all channels
6517 it has joined and thusly sends SIGNOFF notify type.
6519 * Rewrote the NAMES list generation in server by removing two excess
6520 loops. The lists are created now inside one loop.
6522 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * silc_server_remove_channel_user checks now also global list
6525 for channel and client.
6527 * silc_server_new_channel_user checks now both local and global
6528 list for channel and client. Fixed a bug in client id decoding.
6529 Used to decode wrong buffer.
6531 * silc_server_channel_message checks now both local and global
6532 list for channel entry.
6534 * Tested channel joining (hence JOIN) in router environment
6535 successfully. Tested with two routers, two servers and two
6538 * Tested channel message sending in router environment successfully.
6540 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Added silc_server_save_channel_key into server.[ch] to save the
6543 received channel key in Channel Key payload processing. It is
6544 also used in JOIN command reply handling.
6546 Equivalent function silc_client_save_channel_key added into
6547 client.[ch] into client library.
6549 * Changed JOIN command reply to send information whether the channel
6550 was created or not (is existing already) and the channel key
6551 payload. Changed protocol specs accordingly.
6553 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6554 the request was sent by ID and not by nickname. Crashed on
6557 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6560 now correctly save the received data.
6562 * silc_server_free_sock_user_data now notifies routers in the
6563 network about entities leaving the network.
6565 At the same time implemented functions silc_server_remove_id
6566 and silc_server_send_remove_id to receive and send REMOVE_ID
6567 packets. The packet is used to notify routers in the network
6568 about leaving entities. The ID removed will become invalid in
6571 * Added function silc_idlist_del_server into server. Removes and
6572 free's server entry from ID list.
6574 * silc_server_private_message function now checks, if we are router,
6575 that the destination ID really is valid ID, naturally.
6577 * In router when NEW_ID packet is received (for new client) the
6578 hash of the Client ID is saved in the ID Cache but the
6579 client->nickname is set to NULL, instead of putting the hash
6582 IDENTIFY command now also checks that client->nickname must be
6583 valid. If it is not if will request the data from the server who
6584 owns the client. Added new function
6585 silc_server_command_identify_check.
6587 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6588 to set the command to already allocated Command Payload.
6590 * Tested private message sending in router environment with two
6591 routers, two servers and two clients. Fixed minor bugs and now
6594 * Fixed segfault from client's NAMES command. Used to crash if
6597 * Forwarded packets must not be routed even if it is not destined
6598 to the receiver. Changed server code comply with this.
6600 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Added `require_reverse_mapping' boolean value to ServerParams
6603 structure. If TRUE (not default) the server will require that
6604 the connecting host has fully qualified domain name.
6606 If the reverse mapping is not required and hostname could not be
6607 found the IP address is used as hostname.
6609 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6611 * Implemented version string checking to both client and server.
6612 The check is incomplete currently due to the abnormal version
6613 strings used in development version of SILC.
6615 * Changed all command functions in server to use the new
6618 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Changed char *data to unsigned char *data in ID Cache system to
6621 support binary data as ID Cache data. Changed code to support
6622 binary data in lib/silccore/idcache.c.
6624 * Renamed silc_server_packet_relay_command_reply to
6625 silc_server_command_reply as it is normal packet receiving
6626 function. Rewrote the function to accept command replys for
6627 servers and not only for clients.
6629 * Mark remote router always as registered server if we are connecting
6630 to it. Otherwise, commands sent by the router to us are ignored.
6632 * All ID List find routines now returns the ID Cache Entry pointer
6633 as well if requested.
6635 * WHOIS command works now in router environment, tested with two
6636 routers, two servers and two clients.
6638 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6639 in router environment (as it is almost equivalent to WHOIS) but
6640 hasn't been tested thoroughly. Added new functions:
6642 silc_server_command_identify_parse
6643 silc_server_command_identify_send_reply
6644 silc_server_command_identify_from_client
6645 silc_server_command_identify_from_server
6647 * Disabled route cache adding because adding two different ID's with
6648 same IP replaces the old cache entry thus giving wrong route.
6649 The entry->router->connection is always the fastest route anyway
6650 so route cache may not be needed. Of course, new routes maybe
6651 established after receiving the ID when the entry->router->connection
6652 might not be anymore the most optimal.
6654 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Add route cache for received ID for fast routing.
6658 * Added silc_server_packet_route to route received packet on router
6659 that is not destined to us.
6661 * Renamed silc_server_get_route to silc_server_route_get.
6663 * Added id_string and id_string_len fields into SilcServer to
6664 include encoded ServerID for fast comparing without excess
6665 encoding of the ID's.
6667 * Cleaned up WHOIS command on server side. Added following static
6670 silc_server_command_whois_parse
6671 silc_server_command_whois_check
6672 silc_server_command_whois_send_reply
6673 silc_server_command_whois_from_client
6674 silc_server_command_whois_from_server
6676 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6677 arguments in command replies. All command functions should be
6678 updated to use this macro.
6680 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Minor typo fixes on command reply handling on server.
6684 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6686 * Added silc_server_command_add_to_channel internal routine to add
6687 the client to the channel after router has created the channel and
6688 sent command reply to the server.
6690 * Added generic silc_server_send_command to send any command from
6693 * Use static buffer with ID rendering instead of duplicating data.
6695 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Fixed a channel user mode bug when joining to a channel server gave
6698 everybody channel founder rights, oops.
6700 * We mark ourselves as the router of the incoming server connection
6701 if we are router ourselves. This way we can check in some packet
6702 sending functions whether it is locally connected server. For
6703 incoming router connections we put NULL.
6705 * For router sending packets locally means now always sending the
6706 packet cell wide; to local clients and local servers. For normal
6707 server sending packet locally means sending it to only local
6710 * Fixed the JOIN command to really work in router environment. If the
6711 channel is created it is always created by the router. Router is
6712 also responsible of making the initial joining to the channel,
6713 sending JOIN notify to the sending server and distributing
6714 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6715 does not exist server doesn't do anything else but forward the
6716 command to the router which performs everything.
6718 * Added silc_server_send_channel_key function to send the Channel Key
6721 * Added silc_server_create_channel_key to create new channel key. The
6722 channel key is now re-generated everytime someone joins or leaves
6723 a channel, as protocol dictates. Note: channel->key_len is the
6726 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6729 packet_receive.[ch] to separate packet sending and receiving
6730 routines. The server.[ch] now includes everything else including
6731 actual packet processing (writing and reading data) and other
6734 Renamed silc_server_private_message_send_internal to
6735 silc_server_send_private_message. The routine is still though
6736 used only to relay private messages as server does not send
6737 private messages itself.
6739 Renamed silc_server_new_channel to silc_server_create_new_channel
6740 and added new function sicl_server_new_channel that handles the
6741 incoming New Channel packet. Added also new sending function
6742 silc_server_send_new_channel to send New Channel Payload.
6744 * Added new function silc_server_notify to process incoming notify
6745 packet to the server/router. Server may then relay the notify
6746 to clients if needed.
6748 * Added new function silc_server_new_channel_user to process incoming
6749 New Channel User packet. Router will redistribute the packet and
6750 send JOIN notify to its local clients and locally connected servers
6751 if needed. Normal server will send JOIN notify to its local client
6752 on same channel when received this packet. Added also corresponding
6753 sending function silc_server_send_new_channel_user to sent the
6756 * Added boolean route argument to send_notif_to_channel and
6757 packet_send_to_channel functions to attempt to route the packet
6758 if it is TRUE and send only locally if it is FALSE.
6760 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * silc_server_replace_id now broadcasts the received replace ID
6763 packet if it is not broadcast packet already. The router must
6764 broadcast to inform other routers about changed ID.
6766 * Added backpointer to server's router into SilcServer context in
6767 silcd/server_internal.h.
6769 * Fixed silc_server_packet_broadcast to send correct broadcast
6772 * The channel key is now distributed to the local client as soon
6773 as it is received from the router (in router environment) so that
6774 no other packet may be sent for the channel until client has
6777 * silc_server_remove_channel_user now broadcasts the received
6778 Remove Channel User packet if it is not broadcast packet already.
6779 The router must broadcast to inform other routers about removed
6782 * Added users field into SilcPacketContext that is a reference count
6783 of the context. One can increase the reference count by calling
6784 silc_packet_context_dup which is now changed to just increase the
6785 reference count instead of duplicating the data. The reference
6786 count is decresed by calling silc_packet_context_free that will
6787 free the data after the reference count hits zero.
6789 For now on the packet context and everything allocated into it
6790 (including the raw packet from network) must be freed by calling
6791 the new silc_packet_context_free function. Added also new function
6792 silc_packet_context_alloc that must be used now to allocate the
6793 context. This also means that if a routine is asynchronous from
6794 silc_[client/server]_packet_parse_type the packet context must
6795 be duplicated by calling silc_packet_context_dup. Otherwise it
6796 gets free'd after silc_[client/server]_packet_parse_type returns.
6797 Also, one must remember that if packet is duplicated then its
6798 reference count must be decresed by calling the free function as
6799 many times as it was duplicated.
6801 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6802 from both client and server.
6804 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Made joining to a channel working in router environment.
6808 * Cleaned up JOIN command on server side and create function
6809 silc_server_command_join_channel internal routine to make the
6812 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Changed silc_command_pending list to SilcDList. Also, added
6815 `ident' field to SilcServerCommandPending structure to identify
6816 the reply and to call correct callback.
6818 Added silc_server_command_pending_check function to replace the
6819 corresnponding macro. The silc_command_pending list is not
6822 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6823 to set identifier to previously allocated Command Payload. It
6824 is used to set identifier for command when resending Command
6827 * Added silc_command_payload_encode_payload to encode Command
6828 Payload buffer from SilcCommandPayload structure.
6830 * Added silc_argument_payload_encode_payload to encode Argument
6831 payload buffer from SilcArgumentPayload structure.
6833 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Changed WHOIS command to support router connection on server side.
6836 The whois request is always sent to router unless the server is
6837 standalone server. After server has received the reply from the
6838 router will it send the reply to the client.
6840 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6841 broadcast received broadcast packet. The function is used only
6842 by router. The broadcast packet is always sent to the router's
6845 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6846 render given ID to printable string, for log files for example.
6848 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Made basic router to router connections working. At least they
6851 can now connect to each other but nothing really works the way
6852 they are supposed - yet.
6854 * Added new initiator token to RouterConnection configuration
6855 file in silcd/serverconfig.[ch]. It is used to tell whether we
6856 are the initiator to the remote router or whether we'll expect
6857 the other end to connect.
6859 * Moved registering of listener task to silc_server_init, hence
6860 the server starts listenning as soon as it is run, even if it
6861 does not have connections to other routers. Let's see how well
6864 * Changed default connection retry timeouts for more suitable in
6867 * Removed cipher and such arguments from silc_idlist_add_client
6868 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6869 Added new function silc_idlist_add_data to add the keys and stuff
6872 * Added SilcIDListData structure and added it to SilcClientEntry
6873 and SilcServerEntry as their first field in the structure. This
6874 way we can explicitly cast the ID entries to the SilcIDListData
6875 structure and get common data for the entries. In past, we had
6876 to first check what type of connection it is and then cast it to
6877 correct ID entry type. Now, we can directly cast the opaque
6878 pointer to the SilcIDListData (no matter what ID entry it actually
6879 is) and get the data needed.
6881 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6884 in some circumstances even if threre were timeout tasks, though not
6885 IO tasks, but tasks anyway. Now fixed.
6887 * Defined SilcServerConnection structure to hold connection specific
6888 stuff about directly connected servers and routers. The definition
6889 is currently in silcd/server_internal.h. I thought about having
6890 a bit more important role fro this struct but for now it is used
6891 only when connecting to other server (or router actually).
6893 * Added connecting retry support in server when connecting to
6894 router(s). The retry feature implement exponential backoff
6895 algorithm. Also, added SilcServerParams structure to hold default
6896 parameters for server. For now, it include these retry settings
6897 and are hard coded. After server is moded to be as Silc Server
6898 Library this structure will be more important.
6900 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Changed client librarys channel->clients table to SilcList and
6903 changed code accordingly.
6905 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Changed client's channel table to SilcList and changed code
6908 accordingly. Also changed SilcChannelClientEntry to include back-
6909 pointer to the channel so that client entry can use that structure
6910 as list as well and we have fast cross-reference to the channel.
6911 This change dramatically decreased the complexity of channel
6912 handling with client entry and vice versa (removed one extra
6913 loop when searching for channel entry from many functions).
6915 * Changed server->sim from table to SilcDList and changed code
6918 * NAMES command can now be used from user interface. It will show
6919 the user list on the channel, neatly.
6921 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6922 Code now saves realname of the user if it becomes available.
6924 * Renamed configure.in to configure.in.pre and made ./prepare
6925 script to automatically add correct version string to
6926 configure.in which it creates from configure.in.pre.
6928 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * NAMES command reply now shows users mode with the nickname when
6933 * Moved silc_client_ch[u]mode[_char] functions from
6934 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6935 place sucks, they are utility functions and should be in some
6938 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6940 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6943 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Added TRQ (efficient deque and list library) into lib/trq. This is
6948 a very good list library that is currently used in the SILC. Defined
6949 SilcList API over the library because I didn't like the API very
6950 much. See lib/trq/silclist.h for the API and examples of how to
6951 use the API. Fixed various places in the code to use the new
6952 SilcList API. The SilcList is meant for lists that has a structure
6953 already defined as a list. It is not suitable to add just some
6954 context to the list (in TRQ, the context is the list actually).
6956 So, I defined SilcDList that can be used for the purpose where
6957 predefined list structure does not exit. This can be used as
6958 such list. Now some context just can be added to the SilcDList.
6959 Currently this list is not used in the SILC just yet, though there
6960 are a lot places where this can replace dynamically allocated
6961 tables and I will fix these places, later, to use SilcDList.
6962 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6963 and use TRQ internally).
6965 Also fixed some annoying warning messages that the original TRQ
6966 code generated. Also minor changes to TRQ's Makefile.in.
6968 * Added support for querying by Client ID to both WHOIS and
6969 IDENTIFY commands into server, as required by the protocol.
6971 * Removed method function pointers from SilcBuffer structure. They
6972 weren't used to anything and just increased the context size for
6973 no good reason. This change also made silc_buffer_alloc and
6974 silc_buffer_free functions inline functions.
6976 * Disabled command flooding detection support until it's fixed so
6977 that it accepts commands in but does not execute them more than once
6980 * Added silc_net_localhost(), to return local hostname, into
6981 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6982 that must be initialized before calling silc_client_init.
6984 * Added new function: silc_server_send_notify_on_channels to send
6985 notify messages to all channels client has joined. It is assured
6986 that the message is sent only once per client.
6988 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6989 lib/silcutil/silcutil.[ch] as silc_format function. The new
6990 function is generic and is used by server as well, not only by
6991 the logging routines.
6993 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6994 the provided version string was not acceptable. Added new function:
6995 silc_ske_check_version into lib/silcske/silcske.h. The function
6996 must be implemented by the application (client or server) and it
6997 does not reside in the SKE library. The function checks the version
6998 string remote end sent.
7000 * Added back pointers (to opaque context and to SilcSocketConnection)
7001 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7003 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7004 duplicate packet context structure.
7006 * Changed `notify' client operation to send same arguments as client
7007 receives from server except for ID's. ID's are mapped to correct
7008 ID entry and that is returned. Also, if channel entry is not sent
7009 by server but the notify is for channel the channel entry is sent
7010 to application (otherwise application doesn't know that it is for
7011 channel (library gets it from packet's Destination ID)).
7013 * Added silc_client_remove_from_channels into client library to
7014 remove a client from all channels it has joined to. Used when
7015 received SIGNOFF notify from server. Added also new function
7016 silc_client_replace_from_channels to replace old ID entry with
7017 new ID entry on all channels. Used when received NICK_CHANGE
7020 * Fixed ID Cache list handling in silc_idlist_get_client in
7021 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7022 to get (or query) client by ID.
7024 * Updated TODO list.
7026 * Added connection authentication status message defined by the
7027 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7028 support for these into the code in client and server side.
7030 * Added generic function silc_client_send_command to send any command
7031 with variable argument list. Application should use this function
7032 to send commands if the command functions provided by the library
7033 does not suite for the application's user interface needs.
7035 * Added new `failure' client operation. Application is notified about
7036 received failure packet if client is executing a protocol. In this
7037 case the protocol's execution has failed.
7039 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7040 is required by the protocol.
7042 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7043 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7046 * Added status flag to SilcSKE object to indicate realtime status
7047 of the SKE protocol.
7049 * Application receives now exactly same command reply arguments as
7050 the library receives from server. However, if ID is received the
7051 corresponding ID entry is returned to the application (eg. Client
7052 ID is mapped to correct SilcClientEntry entry and that is returned).
7053 Changed command_reply client operation due to this change.
7055 * Changed all ID's in commands and in command replys as ID Payloads.
7056 Change affected both client and server side codes.
7058 All ID's sent in SILC network (with execption of ID's in SILC
7059 Packet header) are sent in ID Payload to support variable length
7062 * Server now notifies nick changes and notifies all clients on
7063 the channels about the new nickname (about the new Client ID,
7066 * Implemented CMODE command to change channel modes. Supports all
7067 channel modes defined by the protocol specs except ban and invite
7068 lists. (Also, private channel key mode is supported but support for
7069 setting private channel key in client is missing, thus, this mode
7070 has no effect on client side (except that server requires that the
7071 client uses private channel key and normal channel traffic does not
7074 Also, invite mode works per se, but INVITE command does not work
7075 yet correctly, so you can set channel as invite only channel but
7076 inviting clients to the channel does not work (it is yet to be
7077 thought what's the best way to do it).
7079 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7080 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7081 Implemented CUMODE command to change user's mode on the channel.
7082 Supports all modes defined by the protocol specs.
7084 * Added NAMES command reply to return users modes on the channel.
7086 * Removed unnecessary and slow ciphers from lib/silccrypt.
7088 * Set SO_KEEPALIVE option to connection sockets by default.
7090 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7092 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7093 redefined the Notify Payload into protocol specs.
7095 * Added silc_id_payload_parse_id to get ID directly from raw
7098 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7100 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7101 accept searching by Client ID as well.
7103 * Added support for LEAVE and SIGNOFF notify types in client library.
7105 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7106 to parse ID Payload from raw data.
7108 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7110 * Added flags parameter into silc_ske_assemble_security_properties
7111 function in lib/silcske/silcske.[ch].
7113 * Changed notify client operation to fit better for notify messages
7114 sent by server. The notify payload received from server is now
7115 passed to the application (after parsing it to SilcNotifyPayload).
7116 It is application's responsibility to retrieve the arguments
7117 from the payload and show the message the way it wants. The message
7118 sent by server is implementation specific.
7120 * Changed public keys to comply with the protocol specification.
7121 Old public keys are not supported anymore and are not compatible.
7123 * Removed nickname from Channel Payload as the latest draft removed
7124 it. The client must resolve the nickname from the NAMES command
7125 reply received when it joined the channel.
7127 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7129 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7131 * Fixed some errors in protocol specification drafts.
7133 * Created lib/silccore/silcnotify.c to implement Notify Payload
7134 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7135 generic payloads described by protocol specifications. The file
7136 includes implementations for ID Payload and Argument Payload.
7138 * Changed Command Payload implementation to use the new Argument
7139 Payload. Changed command_xxxx_payload to command_payload_xxxx
7140 to comply with SILC coding conventions.
7142 * Added suppport for Argument Payload handling in Notify Payload
7143 implementation as protocol requires it. Added the new support
7144 into server and client lib as well.
7146 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Added support for multiple nicknames on same channel. [n] is
7149 added locally to the nickname if there are more than one same
7150 nicknames on the channel.
7152 * Server now sends all nicknames that matched WHOIS request.
7153 Client also shows the list received from server.
7155 * Added TOPIC command to client side. User can now set and show
7156 current topic on channel.
7158 * Added MOTD command to client and server. Also, server sends the
7159 motd when client connects to the server.
7161 * Changed version strings to comply ISO 8601.
7163 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7165 * Fixed protocol error handling in client library. It should now
7166 cope even if the SKE fails for some reason.
7168 * Made new protocol specification drafts for submitting to IETF.
7170 * Implemented TOPIC command to server in silcd/command.c.
7172 * Added two new notify types into lib/silccore/silcnotify.h:
7173 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7174 notify nickname change and topic setting/change on a channel.
7176 * API change of command_reply operation in client library. The
7177 application gets now the status type received from server as well.
7179 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7181 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7183 * Cras fixed and optimized the packet handling even further and
7184 it should work now. Minor change to the prototype of function
7185 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7187 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Added new function into lib/silcutil/silcschedule.[ch]:
7190 silc_schedule_with_fd to select() a specified fd. The function
7191 returns after timeout expires or data arrives or goes. The
7192 function is used by packet routines to wait that all data is
7193 received from network.
7195 * Fixed data reading from network in lib/silccore/silcpacket.c.
7196 The code now assures that all data is read from the fd and then
7197 continues packet processing. This was a bug fix since the code
7198 used to drop some data in some circumstances.
7200 * Added new function into lib/silcclient/client.[ch]:
7201 silc_client_start_key_exchange to start key exchange after
7202 connection has been established to server. The code internally
7203 now uses this funtion but its main purpose was to provide it
7204 for applications that perform their own connecting. After
7205 application has created a connection it merely calls this
7206 function to start the key exchange between client and server.
7207 The library takes care of everything else after that.
7209 Updated also lib/silcclient/README to explain the usage of
7212 * Do not send to application information that connection has
7213 been established. Application gets notified it by connect
7216 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Applied cras's patch to add silc_schedule_one function. The
7219 function runs scheduler once and returns.
7221 * Fixed the scheduler after cras messed it up. The timeout
7222 handling works now as it's supposed to work.
7224 * Added into lib/silccore/ silcnotify.h to include notify
7225 message types support. Changed silc_server_send_notify*
7226 functions, in server.[ch], to support those new notify types.
7227 Added the support for the notify types into client library,
7228 as well. Added new notify client operation into ops.h in
7231 * Changed silc_server_packet_send_to_channel to send normal
7232 packets instead of just channel message packets. The function
7233 is now used to send the notify packets to channels. It is not
7234 used to send channel message packets anymore, as server never
7237 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7238 va_arg()s as it seems to require it nowadays. I guess, if SILC
7239 is compiled with older va_arg() the new code should work anyway.
7241 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Splitted core library. Core library (lib/silccore) includes
7244 now only SILC protocol specific core (and common) components.
7245 Created new utility library (lib/silcutil) that includes more
7246 generic purpose stuff. The stuff for util library was taken
7247 from the old core library. This was minor and easy split.
7249 * Created SILC Client Library (lib/silcclient) that includes
7250 implementation of the SILC client without user interface. This
7251 was major move from silc/ directory. The code has been changed
7252 so that it is transparent towards the user interface. The
7253 silc/ directory includes now the same user interface as before
7254 and it uses the new client library. Read lib/silcclient/README.
7255 Basicly, the client library performs everything else related
7256 to SILC except user interface handling. Also, configuration
7257 files are considered to be part of user interface and library
7258 does not handle them.
7260 This change also changed a lot of structures, function naming etc.
7261 Most important change was that SilcClientWindow object was
7262 renamed to SilcClientConnection in the client library. Created
7263 also new file lib/silcclient/ops.h. Also added new files
7264 silc/local_command.[ch] and silc/client_ops.[ch].
7266 All these changes were made to make it easier for user interface
7267 designers to create what ever user interface for the SILC client
7270 It is also expected that the server will be moved to lib
7271 directory as well and SILC Server Library will be created;
7272 sometimes in the future.
7274 * Removed Local commands from lib/silccore/silccommand.h as
7275 they are application specific and new client library does not
7276 handle any of those anymore.
7278 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7279 old client implementation in silc/.
7281 * Added support for callback functions in SILC_LOG_* macros.
7282 Application can now set its own callbacks that will be called
7283 instead of using the default functions that will always print
7284 the debug messages to stderr (or stdout). Also, debugging can
7285 now be disabled by setting silc_debug to FALSE and re-enabled by
7286 setting it to TRUE. Note, that logging will still work even
7287 if debugging is disabled.
7289 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7290 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7291 silc_log_reset_debug_callbacks.
7293 * To enable debugging in silc client one must give now -d
7294 option on command line.
7296 * Changed silc_schedule_init to automatically allocate task queues
7297 if they are not allocated before calling it.
7299 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Added GMP 3.1 into math library.
7303 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7306 a channel in SILC network. The packet is used by servers and
7307 routers to notify other routers that user has left a channel.
7308 This little feature was missing until now. Added the feature
7309 to protocol specification as well.
7311 Added functions: silc_server_send_remove_channel_user and
7312 silc_server_remove_channel_user into server.[ch].
7314 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7315 lib/silccore/silcpacket.h. However, they are not implemented
7318 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Fixed joining to a channel and sending channel messages
7321 between server and router. The channel message sending should
7322 now work inside a cell.
7324 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Fixed the private message sending between server and router.
7327 The private message sending should now work inside a cell.
7329 * Added silc_server_replace_id into server.[ch] to replace
7330 existing ID in the SILC network.
7332 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7333 and silc_idlist_replace_server_id into idlist.[ch] in server.
7335 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7337 * Fixed the server to server connections. Server can again now
7338 connect to router. Router to router connections probably does
7341 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Added dynamic protocol registering support. Now protocols can
7344 registered and unregistered on the fly. Patch by cras.
7346 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Added lib/contrib directory to hold routines that some platforms
7349 don't have but are needed by SILC.
7351 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7352 into lin/contrib to provide getopt() and getopt_long() for
7353 those who don't have it.
7355 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7357 * Added AWAY command to client. When away message is set and
7358 client receives a private message packet the client automatically
7359 replies to the sender with the away message.
7361 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7362 bug seemed to be the cause of recent problems when compiling
7365 * Added version detection support to SKE protocol specification
7366 and added the new changes to the SKE implementation as well.
7367 There were other minor changes in the SKE protocol as well.
7369 Many changes in lib/silcske/silcske.[ch] and in
7370 lib/silcske/payload.[ch].
7372 * Added ^U functionality, clear input line. Patch from cras.
7374 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7376 * Mainly small bugfixes on core library. Fixed some debugging
7377 logging and buffer overflow in silclog.c.
7379 * Updated config.sub and config.guess on the distribution tree.
7381 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7383 * Added command lagging support in server. Client may execute
7384 commands now only once in two seconds.
7386 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7388 * Optimized packet reception. MAC computation and checking is now
7389 also more optimized. A lot previously duplicated code is now
7390 used as generic by both client and server.
7392 * Fixed key pair generation in clientutil.c
7394 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * Added into lib/silccore/silcbufutil.[ch] new function;
7397 silc_buffer_realloc.
7399 * Moved generic packet sending/encryption functions to
7400 lib/silccore/silcpacket.[ch] from client and server. Some
7401 rewriting of the functions.
7403 * Moved all generic packet reception/decryption functions to
7404 lib/silccore/silcpacket.[ch] from client and server. The
7405 packet processing is now much cleaner in both client and server.
7406 These were major changes in both client and server.
7408 * Created many common functions in server to do packet sending.
7409 Previously code were duplicated a lot, this has been removed
7412 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Rewrote major parts of the ID cache system. Don't know
7415 whether it is better now or not but at least the API is more
7418 * Major rewrite on ID cache stuff on client because of the ID
7419 cache API changes. Added idlist.c to client.
7421 * Also major rewrite on ID cache stuff on server as well.
7422 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7423 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7424 in hand, instead they are all put into the ID cache system now.
7425 All server_idlist_* routines uses ID cache now instead of
7426 traversing its own lists (those lists does not exist anymore).
7427 SilcIDList though still exists. Also, SilcXXXEntry's are
7430 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7432 * Finally made the SKE implementation compliant to the protocol
7433 specification. All mp integers are now binary encoded as
7434 opposed being HEX encoded.
7436 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7439 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7440 functions: silc_[encode/decode]_pem. Also added function
7441 silc_encode_pem_file to PEM encode with newlines ('\n') for
7444 * SILC public keys are now encoded either PEM or binary. Same
7445 option is for private keys as well. By default private keys
7446 are binary encoded and public keys PEM encoded. Silly HEX
7447 encoding were removed.
7449 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7450 function to create fingerprints.
7452 * Fixed a bug in SHA1; does not change the original data anymore.
7454 * Partly implemented INFO command on client and server side.
7455 Fixed CLEAR command. Changes to SERVER command; show current
7456 server(s) when giving command without arguments. Added
7457 VERSION command to client.
7459 * Added check to server that unregistered connections cannot
7460 execute commands (unless it is specificly allowed).
7462 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Fixed screen refresh.
7466 * Fixed channel joining bug from client. On some circumstances
7467 client tried to join to a channel it had already joined.
7469 * Added public key verification process into client's protocol.c.
7470 The client now verifies the public key from user and saves
7471 it into ~./silc/serverkeys/ directory.
7473 Added into: clientutil.[ch]: silc_client_verify_server_key.
7475 * Changed SKE protocol's silc_ske_initiator_finish function
7476 to accept callback function that verifies the received public
7477 key. Removed old silc_ske_verify_public_key function.
7479 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7482 silc_pkcs_private_key[_data]_set.
7484 * Made the password and public authentication more cleaner in
7485 server's protocol.c.
7487 * Removed historic and obsolete protocol `channel_auth' from
7488 both client and server.
7490 * Removed wrong way of sending command status messages from
7491 server to client in server's command.c. The old way violated
7492 protocol specification.
7494 Changes to silccore/silccommand.[ch]: removed
7495 silc_command_encode_status_payload -> not needed anymore,
7496 changed silc_command_encode_payload_va to accept extra
7497 argument on variable argument list. The argument type must
7498 now be provided to the function. Also, added new function:
7499 silc_command_encode_reply_payload_va which is same as
7500 normal command_encode_payload_va except command status type
7501 is provided as extra argument.
7503 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7505 * Added ~./silc directory handling. The directory includes the
7506 public and private keys for the client.
7508 Added silc_client_check_silc_dir, silc_client_create_identifier
7509 and silc_client_load_keys.
7511 * Implemented SILC protocol compliant public key. Added public
7512 and private key saving to and loading from files.
7514 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
