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

265 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Fixed the buffer formatting and unformatting routines to
268 check the size of 64 bits types with sizeof(). Affected
269 file is lib/silcutil/silcbuffmt.c.
271 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
273 * Removed 0.6.x backwards support.
275 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
277 * Changed all integer type names:
278 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
279 to avoid collisions with other libraries using same type names
282 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
284 * Added `prefer_ipv6' argument to the functions
285 silc_net_gethostbyname[_async]. If it is TRUE it will return
286 IPv6 address over IPv4. If FALSE IPv4 address is returned
287 even if IPv6 address was found. Affected files
288 lib/silcutil/silcnet.[ch].
290 * Added support silc_net_create_connection[_async] to fallback
291 to IPv4 address if IPv6 address could not be used (like if
292 it doesn't work on a specific system). Affected file in
293 lib/silcutil/unix/silcunixnet.c.
295 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

301 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
303 * Added automatic extern "C" { ... } for C++ compilers so the
304 application does not need to define them. Affected file
305 includes/silcincludes.h.
307 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
308 old name went against naming convention. Applications now
309 include "silcclient.h" instead of "clientlibincludes.h".
310 Removed includes/clientlibincludes.h, it is redundant now.
312 * Renamed includes/version.h to silcversion.h.
314 * Added really preliminary support for OS/2 into the util
315 library. Only thread & mutex API is implemented, others
316 are still to be implemented. Created the lib/silcutil/os2/
317 directory. Created also file includes/silcos2.h.
319 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
321 * Added preliminary BeOS support into the util library.
322 Created lib/silcutil/beos/, and implemented all the needed
323 functions to support SILC on BeOS. Created also file
326 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
328 * Added proper initializations to silc's irssi code, so it's
329 now possible to load it as module. Affected files
330 irssi/src/silc/core/silc-core.c,
331 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
333 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

342 * ROBOdoc documented lib/silcutil/silcmemory.h.
343 Added also new function silc_memdup.
345 * Removed lib/silcutil/silcbufutil.h and moved those routines
346 to the lib/silcutil/silcbuffer.h.
348 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Added `user_count' to the SilcChannelEntry which now tells the
351 number of users on the channel. The user count is now saved
352 in normal server of global channels as well. Affected files
353 silcd/server.c, idlist.h, packet_receive.c and command.c.
355 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
356 include file utility functions.
358 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
359 instead of calling directly OS routines.
361 * Fixed NICK change printing in Irssi SILC Client. Fixed
362 KICKED notify printing in Irssi SILC Client. Affected file
363 irssi/src/silc/core/client_ops.c.
365 * Fixed a NICK change bug in client library, to not recreate the
366 client_entry->channels hash table everytime nick is changed.
367 Affected file lib/silcclient/client.c.
369 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
371 * ROBOdoc documented the lib/silcske/silcske.h, and improved
372 the SKE interface a bit.
374 * Fixed padding problem in PKCS#1. The padding was not actually
375 random since the random number generator was used incorrectly.
376 This security bug affects only when encrypting with PKCS#1, and
377 it is not currently used at all in SILC. SILC only use signing
378 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
380 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

390 * Added following new config file settings:
391 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
392 key_exchange_timeout, conn_auth_timeout, connections_max,
395 Implemented all the new config settings handling in the server.
397 Optimized the use of SKE Mutual flag usage. Use it only
398 if connection authentication protocol is not based in public
401 Renamed all SilcServerConfigSection* to SilcServerConfig*
402 to have a bit shorter names.
404 Affected files silcd/serverconfig.[ch], server.[ch], and
407 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

422 * Fixes to the silcd config template. Affected file is
423 doc/example_silcd.conf.in.
425 * Removed type casts from silc_calloc(), conforming to the
426 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
428 * Removed param_name member from client, server, and router
429 section structs, now identifying the param directly.
431 Added CONFIG_FREE_AUTH macro in config file parsing.
433 Affected files are silcd/serverconfig.[ch].
435 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
437 * Fixed command line parameter handling. All SILC initialization
438 is now done in silc_core_init() which also fixes autoconnecting
441 Affected files irssi/src/silc/core/silc-core.c,
442 irssi/src/fe-text/silc.c.
444 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
446 * Added new configuration options and blocks:
447 keepalive_secs, reconnect_count, reconnect_interval,
448 reconnect_interval_max, reconnect_keep_trying and
449 require_reverser_lookup. Added ConnectionParam block, and
450 implemented the connection parameters when connecting as
451 initiator and when accepting connections as responder.
453 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
454 whether given configuration value has been given already.
456 Affected files silcd/serverconfig.[c], server.[c].
458 * Splitted the doc/example_silcd.conf.in. Separated the crypto
459 algorithm parts and created new file silcalgs.conf, that
460 is now included from the example_silcd.conf.in.
462 * Optimized the silc_server_connect_to_router_second to take
463 the connection configuration object from the SilcServerConnection
464 object instead of finding it during the connecting phase.
465 Added the configuration object to SilcServerConnection struct.
466 Affected files silcd/server_internal.h, server.c.
468 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
470 * Add the client on channel after it was resolved at the
471 channel message receiving, and it was not already on the
472 channel. Affected file lib/silcclient/client_channel.c.
474 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
476 * Fixed the public key authentication to allocate always the
477 destination signature buffer instead of using static buffer.
478 Affected file silcd/protocol.c.
480 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
482 * Unified the serverconfig.[ch]'s helper function interface.
483 Affected file silcd/serverconfig.[ch].
485 * Removed doc/example_silc.conf.in since it is redundant.
486 The make install will now install irssi/silc.conf file.
488 * Added new Passphrase and Publickey authentication methods to
489 config file, allowing both public key and passphrase based
490 authentication to be set at the same time.
492 Added `prefer_passphrase_auth' setting in config file which
493 can be used to set to prefer passwd auth if both passwd and
494 public key is set. If not set, public key is preferred.
495 This has effect only when being initiator (responder will try
498 Added support for authentication with passphrase and public key
499 at the same time. The passphrase is tried first always since
500 it is faster to check.
502 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
504 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
506 * Merged the new SILC Config library, with the server parsing
507 support. Read the header file silcconfig.h or the toolkit
508 documentation for the news. Affected files are
509 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
510 silcd/command.c silcd/packet_receive.c silcd/packet_send.c

517 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * The silc_cipher_register, silc_hash_register and
520 silc_hmac_register now checks if the object to be registered
521 is registered already. Affected files are
522 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
524 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Merged new irssi from irssi.org's CVS, the version 0.7.99.
528 Sat Feb 9 14:54:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>

542 * Fixed CUMODE_CHANGE notify handling to change the mode of
543 correct client. Affected file lib/silcclient/client_notify.c.
545 * Make silc_rng_alloc fail if it cannot allocate the sha1
546 hash algorithm. Affected file lib/silccrypt/silcrng.c.
548 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
550 * Fixed the file transfer's key agreement payload to include
551 zero port also if the hostname is NULL because it could not
554 Call file transfer monitor callback now also if error occurs
555 during key agreement protocol.
557 Changed the silc_client_file_send interface to return the
558 SilcClientFileError instead of session id. The session ID
559 is returned into pointer provided as argument.
561 Check that the file exists locally before sending the
562 file transfer request at all.
564 Affected file lib/silcclient/client_ftp.c, silcapi.h.
566 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
567 error than can occur while key agreement protocol. Affected
568 file lib/silcclient/silcapi.h.
570 * Fixed the event_mode CMODE handler to not crash when mode
571 is changed and +k mode is set in the channel. Affected file
572 irssi/src/silc/core/silc-channels.c.
574 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
575 SILC_LOG_WARNING to give out Warning and not Error. Affected
576 file lib/silcutil/silclog.c.
578 * Fixed the channel message payload decryption in the function
579 silc_channel_message_payload_decrypt to not modify the original
580 buffer before it is verified that the message decrypted
581 correctly. Otherwise, next time it is called with correct
582 channel key it won't encrypt since the payload is corrupted.
583 Affected file lib/silccore/silcchannel.c.
585 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Do not constantly resize the window. A fix patch by cras.
588 Affected file irssi/src/fe-text/screen.c.
590 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
593 Affected file lib/silcutil/silcnet.c.
595 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
597 * Fixed a bug in hash table internal routine for traversing
598 the table with foreach callback. The current entry may
599 become invalid in the callback but it was referenced after
600 the callback returned.
602 Do not allow auto rehashing of hash table during the
603 silc_hash_table_foreach operation, for same reasons as it is
604 not allowed for SilcHashTableList. Affected files are
605 lib/silcutil/silchashtable.[ch].
607 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
609 * Defined DLLAPI into silcincludes.h and silcwin32.h for
610 Win32 DLL. extern's in header files are now declared with
613 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Fixed private message handling. It used some old code that
616 caused the client to crash. Affecte file is
617 lib/silcclient/client_prvmsg.c.
619 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
621 * Added function silc_client_add_channel,
622 silc_client_replace_channel_id, and removed functions
623 silc_client_new_channel_id and silc_idlist_get_channel_by_id
626 * Added cross reference of the joined channels to the
627 SilcClientEntry, and changed the SilcChannelEntry's
628 users list to SilcHashTable. The affected files are
629 lib/silcclient/idlist.[ch].
631 * Fixed a bug in hash table tarversing. While the hash table
632 is traversed with SilcHashTableList the table must not be
633 rehashed. It is now guaranteed that auto rehashable tables
634 are not rehashed while tarversing the list. Also defined that
635 silc_hash_table_rehash must not be called while tarversing
636 the table. Added function silc_hash_table_list_reset that must
637 be called after the tarversing is over. The affected files are
638 lib/silcutil/silchashtable.[ch].
640 * Changed all hash table traversing to call the new
641 silc_hash_table_list_reset in server and in client library.
643 * Added function silc_client_on_channel to return the
644 SilcChannelUser entry if the specified client entry is joined
645 on the specified channel. This is exported to application as
646 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
648 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Fixed founder regaining problem with JOIN command on normal
651 server. The notify for mode change must be sent always and
652 not only if !cmd->pending. Affected file silcd/command.c.
654 * Fixed the WHOWAS command's reply sending to support the
655 lists correctly. Affected file silcd/command.c.
657 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
659 * When sending JOIN command to router for processing the
660 sender's old command identifier was not saved back to the
661 sender's command context, fixed now. The affected file is
664 * Create the key in JOIN command of the router did not return
665 the channel key, added check for this. Affected file is
668 * Fixed a channel ID update bug in JOIN command reply. Do
669 not directly upgrade the ID but call the function
670 silc_idlist_replace_channel_id if the ID was changed.
671 Affected file silcd/command_reply.c.
673 * Fixed memory leaks from command calling if it would fail.
674 Affected file silcd/command.c.
676 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Applied patches from cras:
680 Memory leak fixes around libaries, irssi window resize fix,
681 new silclist.h and silcdlist.h, all extern inline changed to
684 * Removed dotconf from lib/dotconf, not needed anymore.
686 * Removed TRQ from lib/trq, not needed anymore.
688 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
689 with server connections. Later this will be configurable
690 in config file after new config file is done. Affected file
693 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Fixed a crash in server related to channel announcements.
696 Affected file silcd/server.c.
698 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Fixed memory leaks in silc_server_create_new_channel*
701 functions. Affected file silcd/server.c.
703 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
704 which ID was changed. This way the router will send the
705 user list for the channel again, and server won't be in
706 desync in some rare circumstances. Affected file is
707 silcd/packet_receive.c.
709 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
711 * Check for NULL socket pointer in the function
712 silc_server_packet_send_to_channel_real. Affected file
715 * Fixed the BAN notify handling to correctly remove ban
716 list. Affected file silcd/packet_receive.c.
718 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
720 * Fixed some header addition to Toolkit distribution in
721 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
723 * Added lib/silcclient/client_ops_example.h as an template
724 file for application programmers to quickly start using
725 the SilcClientOperation functions in their application.
726 Updated the lib/silcclient/README as well to tell about this
727 nice file made available.
729 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
731 * Call silc_server_remove_from_channels when removing client
732 entry when NO_SUCH_CLIENT_ID was received. Affected file
733 is silcd/command_reply.c.
735 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
737 * Added server & router operator statistics updating. Affected
738 file silcd/packet_receive.c and silcd/command.c.
740 * Fixed the SERVER_SIGNOFF notify handling on normal server
741 not to save the history information for clients. Same was
742 fixed earlier in remove_clients_by_server function, but not
743 here. Affected file silcd/packet_receive.c.
745 * Raised the default connection-retry count from 4 to 7 in
746 server. Affected file silcd/server.h.
748 * Cancel any possible reconnect timeouts when we start the
749 key exchange. Affected file silcd/server.c.
751 * Do not reconnect on connection failure when SCONNECT was
752 given. Affected files silcd/server.[ch].
754 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
756 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
758 * Fixed the NICK command to always give the unformatted
759 nickname to the one giving the NICK command. If unformatted
760 nickname is cached already it will be formatted and the
761 local entry will always get the unformatted nickname.
762 Affected file lib/silcclient/idlist.c.
764 * Fixed some double frees from client library commands.
765 Affected file is lib/silcclient/command.c.
767 * Fixed CUMODE command in server to assure that no one can
768 change founder's mode than the founder itself, there was a
769 little bug. Affected file silcd/command.c.
771 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
773 * Removed the SilcClientCommandDestructor from the client
774 libary, it is not needed anymore. Affected files are
775 lib/silcclient/silcapi.h, command[_reply].[ch],
776 client_notify, idlist.c.
778 * Fixed GETKEY command to first resolve client, and then
779 resolve the server only if the client was not found, instead
780 of resolving both at the same time. Affected file is
781 lib/silcclient/command.c.
783 * Added silc_client_start_key_exchange_cb and lookup the
784 remote hostname and IP address before starting the key
785 exchange with server. The affected file is
786 lib/silcclient/client.c.
788 * The server's public key is now saved using the IP address
789 of the server and not the servername for the filename.
790 The hostname public key filename is checked as an fall back
791 method if the IP address based filename is not found.
793 Fixed the GETKEY command to save the fetched server key
796 Print the remote server's hostname now when new key is
797 received during connection process. Affected file is
798 irssi/src/silc/core/client_ops.c.
800 * Return always our own public key to the client if it asks
801 for it with GETKEY command. Affected file silcd/command.c.
803 * Removed the use_auto_addr variable from default config
804 file since it was in wrong section. Affected file is
807 * Fixed TOPIC_CHANGE notification to not route it when it
808 was sent using silc_server_send_notify_to_channel function.
809 Affected file silcd/command.c.
811 * Fixed silc_server_send_notify_kicked to send the kicker's
812 Client ID also, it was missing. Affected files are
813 silcd/command.c, silcd/packet_send.[ch].
815 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
817 * Do not save client history information in SERVER_SIGNOFF.
818 Fixes the bug in normal server that it does not detect
819 the client becoming valid after the server becomes back
820 online. Affected file silcd/server_util.c.
822 * Added `sock_error' field into the SilcSocketConnection
823 context. When error occurs during socket operation (read
824 or write) the error is saved. Added also new function
825 silc_socket_get_error to return human readable socket error
826 message. Affected files are lib/silcutil/silcsockconn.[ch],
827 lib/silcutil/unix/silcunixsockconn.c, and
828 lib/silcutil/win32/silcwin32sockconn.c.
830 * The server now prints the socket error message in the
831 signoff for client. Affected file silcd/server.c.
833 * Fixed the `created' channel information sending from router
834 to server in JOIN command. Checks now whether the channel
835 really was created or not and set it according that.
837 Fixed the JOIN command to use the client entry's current
838 ID during the joining procedure instead of the one it sent
839 in the command (it is checked though), since it can change
840 between the packet processing and command processing, and
841 would just case unnecessary pain in the client end. Affected
842 file silcd/command.c.
844 * Fixed a channel key payload sending to use correct channel
845 ID when the server was forced to change the channel's ID by
846 router. Router sent the key payload with the old Channel ID.
847 Affected file silcd/packet_receive.c.
849 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Call silc_server_save_channel_key only if the key payload
852 was provided in the JOIN command's command reply. Affected
853 file silcd/command_reply.c.
855 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
857 * Fixed silc_mp_sizeinbase to return the value correctly with
858 MPI. Affected file lib/silcmath/mp_mpi.c.
860 * Fixed the stop_server signal to correctly stop the scheduler
861 and gracefully stop the server when SIGTERM or SIGINT signals
862 are received. Affected file silcd/silcd.c.
864 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
866 * Simple handling of TERM and HUP signals. Also added some log
867 flushing call around. Affected file is
870 * Fixed small bugs in silclog.c. Now buffering output will take
871 effect after 10 seconds since startup: This will ensure that
872 no important startup messages are lost. Also output redirection
873 will preserve original format ([Date] [Type] message).
874 Affected file is lib/silcutil/silclog.c.
876 * Added two options to the config file, in the logging section:
877 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
878 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
880 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
882 * Do not print the warning about log files not being initialized
883 more than once to avoid excess logging. Affected file is
884 lib/silcutil/silclog.c.
886 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
887 the SIM copying in make install in Makefile.am.pre.
889 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
891 * Rewritten silclog APIs. Globally interesting changes follows:
892 silc_log_set_files() changed to silc_log_set_file().
893 silc_log_set_callbacks() changed to silc_log_set_callback().
894 ROBOdoc documented silclog header file.
895 SilcLogCb now returns bool to wether inihibit the default
896 handler or not (to keep the old behaviour return always TRUE).
897 The new APIs should also fix the problem of the
898 silcd_error.log file that was written in the current directory.
901 Log files streams will remain opened after silc_log_set_file()
902 call, means less CPU usage notably on high traffic servers.
903 File streams are now full buffered, and flushed to the disk
904 every 5 minutes, lesses HD activity and CPU usage.
905 Messages can be redirected, allowing admins to configure
906 one single logfile for all server messages.
907 the silc_log_quick global variable to activate fast-logging.
908 Affected files lib/silcutil/silclog.[ch]
910 * Changed some code to conform new silclog APIs. Affected
911 files are doc/example_silcd.conf.in, silcd/server.c
912 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
915 * Fixed a memory leak that could occur in some situations.
916 Affected file silcd/serverconfig.c.
918 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Added the silc_client_del_client to remove the client from
921 all channels as well. Affected file lib/silcclient/idlist.c.
923 * Fixed the client library to correctly remove the client
924 from all channels when the client entry is being destroyed.
925 Affected file lib/silcclient/client_notify.c, command.c.
927 * Added auto-nicking support to the client library. If the
928 applicatio now sets client->nickname it will be sent to the
929 server after connecting by the library. This way for example
930 SILCNICK (or IRCNICK) environment variables will have effect
931 and always change the nickname automatically to whatever
932 it is wanted. Affected file lib/silcclient/client.[ch].
934 * Renamed silc_server_command_bad_chars to the
935 silc_server_name_bad_chars and moved it to the
936 silcd/server_util.[ch]. Added also new function
937 silc_server_name_modify_bad to return nickname that
938 includes bad characters as new nickname without those
939 bad characters. This check and modify is now used in
940 silc_server_new_client when the username is initially set
941 as nickname, so it must be checked to be valid nickname.
942 Affected file silcd/packet_receive.c.
944 * The nickname length is now taken from the packet for real
945 and not trusted to strlen() since it clearly can return
946 wrong length for nickname including bad characters. This
947 also applies to channel names. Affected file silcd/command.c.
949 * Removed the lib/silcsilm/modules directory. Modules are now
950 compiled into the lib/silcsim. Fixed the copying of the
951 modules to follow symbolic links in Makefile.am.pre.
953 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
955 * Fixed silc_string_regexify list creation. Fixes bugs with
956 BAN and INVITE commands in server. The affected file is
957 lib/silcutil/unix/silcunixutil.c.
959 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Removed the command destructor entirely from the server's
962 command and command reply routines. It is not needed, and
963 its usage was buggy and caused crashes. Affected files are
964 silcd/command[_reply].[ch].
966 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Cancel protocol and NULL sock->protocol if timeout
969 occurred during protocol. Affected file silcd/server.c.
971 * Cancel protocol timeouts always before calling the final
972 callback, to assure that after final callback is called
973 no other state will be called for the protocol anymore.
974 Affected file silcd/protocol.c.
976 * Print error log if incoming connection configuration could
977 not be found. Affected file silcd/server.c.
979 * Fixed JOIN command to correctly save the founder mode
980 to the client on normal SILC server, when the channel
981 was created by the router. Affected file silcd/command.c.
983 * Fixed LIST command (hopefully) to send correct reply
984 packets. Affected file silcd/command.c.
986 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
988 * The silc_packet_receive_process now returns FALSE if the
989 read data was invalid packet, and TRUE if it was ok.
991 The server now checks that if unauthenticated connection
992 sends data and its processing fails the server will close
993 the connection since it could be a malicious flooder.
995 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
997 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Make sure the warning about error opening a log file is
1000 printed only once and not everytime it fails (produces
1001 too much useless log). Affected file lib/silcutil/silclog.c.
1003 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1005 * Made the silc_server_daemonise() function more readable.
1006 Affected file silcd/server.c.
1008 * Pid file is now optional, the user may comment it out from
1009 the config file. Removed define SILC_SERVER_PID_FILE, we
1010 don't need a default any longer. Affected file
1011 configure.in.pre, lib/Makefile.am.pre.
1013 * Make some use of the pid file. The server now dies at startup
1014 if it detects a valid pid file on his path. The server would
1015 die anyway in this circumstance, because of the bind() failure.
1016 Affected file silcd/silcd.c.
1018 * No longer compiling lib/dotconf.
1020 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Fixed JOIN command parsing not to crash. Affected file
1023 lib/silcclient/command.c.
1025 * Fied the NICK_CHANGE notify to add the new client entry
1026 even it is resolved. This removes an <[unknown]> nick
1027 thingy bug in the client. Affected file is
1028 lib/silcclient/client_notify.c.
1030 * Do not try to allocate 0 bytes (efence does not like it)
1031 in lib/silccore/silccomand.c when encoding payload.
1033 * Do not take IRCNICK as nickname in Irssi SILC client since
1034 it is not possible to set nickname before hand connecting
1035 the server (TODO has an entry about adding auto-nicking
1038 * Changed the silc_server_command_pending to check whether
1039 there already exists an pending entry with the specified
1040 command, command identifier and pending callback. This is
1041 to fix IDENTIFY and WHOIS related crashes that may register
1042 multiple pending commands with same identifier. Affected
1043 file silcd/command.c.
1045 * Fixed the server to reconnect to the router even if it
1046 was already reconnecting and EOF was received. This to
1047 fix a possibility that the server wouldn't ever try to
1048 auto-reconnect to the router. Affected file silcd/server.c.
1050 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Fixed the server's password authentication to use the
1053 length of the locally saved password, and not the one
1054 sent in the packet. Affected file silcd/protocol.c.
1056 * Fixed same password authentication problem in the
1057 Authentication Payload handling routines in
1058 lib/silccore/silcauth.c.
1060 * Yet another password authentication problem fixed with
1061 channel password handling in silcd/command.c.
1063 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * If first character of string in silc_parse_userfqdn is '@'
1066 then do not parse it. Affected file is
1067 lib/silcutil/silcutil.c.
1069 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Fixed minor bug in IDENTIFY command reply sending, which
1072 caused various weird problems during JOIN when it was
1073 resolving names for users. Affected file silcd/command.c.
1075 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Fixed the IDENTIFY command reply sending to chech better valid
1078 clients. It was possible to send incomplete list of replies.
1079 Affected file silcd/command.c.
1081 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * Added silc_client_command[s]_[un]register functions now to
1084 dynamically register the commands in client library. Removed
1085 the static table of commands. This allows the client library
1086 to call commands without causing the application to know about
1087 what commands library has called.
1089 Removed the INFO command reply kludge to detect when the command
1090 was called by library. Now library use its own command reply
1091 function for INFO command.
1093 Added function silc_client_command_call to call a command.
1094 Application can use it to call command, not access the structure
1097 Now all commands that are sent by the client library (not
1098 explicitly sent by application) use own command reply functions.
1100 Affected files around lib/silcclient/ and in
1101 irssi/src/silc/core/.
1103 * Fixed the WHOIS command reply sending to chech better valid
1104 clients. It was possible to send incomplete list of replies.
1106 Fixed the WHOIS and IDENTIFY to send the request to router
1107 if normal server did not do it and did not find any results.
1109 Affected file silcd/command.c.
1111 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Moved the internal data from SilcClient context into its
1114 own file, not accesible to application. Affected files
1115 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1116 and other files in client library.
1118 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1120 * Added doc/examples installation target in Makefile.am.pre.
1123 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1126 commands the found client entry will be removed from the
1127 cache, after notifying application about the error. Affected
1128 file lib/silcclient/command_reply.c.
1130 * Changed the /MSG to check for exact nickname user gave, and
1131 not let `nick' match `nick@host' if it is only one found. Now,
1132 user must type the exact nickname (like nick@host2) even if
1133 there are no more than one same nicks found. This is to avoid
1134 a possibility of sending nickname to wrong nickname since
1135 `nick' could match `nick@host'. Affected file is
1136 irssi/src/core/silc-servers.c.
1138 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Do not print "you are now server operator" or similar when
1141 giving /away command. Affected files are
1142 irssi/src/silc/core/client_ops.c, silc-servers.h.
1144 * Made the silc_server_command_pending_error_check to send
1145 the same command reply payload it received back to the
1146 original sender of the command. This way all arguments
1147 that was received by the server will be received by the
1148 client too. Affected file silcd/command.c.
1150 * Added the silc_idcache_add to return the created cache entry
1151 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1153 * Add global clients to expire if they are not on any channel.
1154 This is because normal server will never know if they signoff
1155 if they are not on any channel. The cache expiry will take
1156 case of these entries. This is done by normal servers only.
1157 The affected files are silcd/command_reply.c,
1158 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1160 * If server receives invalid ID notification for WHOIS or
1161 IDENTIFY and the ID exists in the lists, it is removed.
1162 Affected file silcd/command_reply.c.
1164 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1165 in client then client entry that it matches is searched and
1166 the nickname is printed on the screen for user. Affected
1167 file irssi/src/silc/core/client_ops.c.
1169 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Use cache entry expire time in the LIST command reply to
1172 purge old entries from the cache after the LIST command
1173 reply has been received. This way we don't have non-existent
1174 entries in the cache for too long. Affected file is
1175 silcd/command_reply.c.
1177 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1179 * If we are normal server, and we've not resolved client info
1180 in WHOIS or IDENTIFY from router, and it is global client,
1181 we'll check whether it is on some channel. If it is not
1182 then we cannot be sure about its validity and will resolve it
1183 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1184 file silcd/command.c.
1186 * Search channel by name (if possible) rather than by ID
1187 in IDENTIFY command's command reply. Affected file is
1188 silcd/command_reply.c.
1190 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1193 Updated specs and implemented it. Affected file silcd/command.c,
1194 silcd/packet_send.c and silcd/packet_receive.c.
1196 * Implemented the <founder auth> payload handling in the JOIN
1197 command. If provided all conditions for channel joining
1198 except requirement to provide correct passphrase can be
1199 overrided by the channel founder. Updated the protocol specs.
1200 Affected file silcd/command.c.
1202 Added support for founder auth in JOIN command in client
1203 library. Fixed the parsing of the JOIN command now to support
1204 all options as they should be. The affected file is
1205 lib/silcclient/command.c.
1207 * Optimized the WHOIS and IDENTIFY commands to send the request
1208 to router only if it includes nicknames or other names. If
1209 they include only IDs then check the local cache first before
1210 routing. Affected file is silcd/command.c.
1212 * Added channels topic announcements. Affected file is
1213 silcd/packet_receive.c and silcd/server.c.
1215 * Fixed the silc_server_send_notify_topic_set to really destine
1216 the packet to channel. Affected file silcd/packet_send.c.
1218 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1219 library. Affected file lib/silcclient/client_notify.c.
1221 * Added UMODE announcements. Affected file silcd/server.c.
1223 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1225 * Memory leak fixes in:
1227 lib/silcutil/silcsockconn.c
1228 lib/silcske/silcske.c
1229 lib/silcske/groups.c
1231 lib/silccrypt/silcpkcs.c
1232 lib/silccore/silccommand.c
1233 lib/silccore/silcidcache.c
1238 * ROBOdoc documented the lib/silcske/groups.h file and a
1239 bit changed the interface for better.
1241 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1243 * Update the client entry context in the ID cache after
1244 nick change. Affected file lib/silcclient/command.c.
1245 Fixes the CUMODE command when regaining founder privileges,
1246 and a little WHOIS problem.
1248 * Fixed silc_net_gethostbyname to correctly call the
1249 inet_ntop. Affected file lib/silcutil/silcnet.c.
1251 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1253 * Added IPv6 support checking to the configure.in.pre, added
1254 also --enable-ipv6 option to override the check. Affected
1255 file configure.in.pre.
1257 * The silc_thread_create now calls the start function
1258 directly if threads support is not compiled in. Removes
1259 ugly #ifdef's from generic code. Affected files are
1260 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1262 * Added silc_net_gethostby[name/addr]_async to asynchronously
1263 resolve. Affected files are lib/silcutil/silcnet.[ch].
1265 * Added support for rendering IPv6 based server, client and
1266 channel IDs. Affected file lib/silcutil/silcutil.c.
1268 * Added support for creating IPv6 based server IDs. Affected
1269 file is silcd/serverid.c.
1271 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1273 * Added silc_net_gethostby[addr/name] into the
1274 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1275 routines. Added silc_net_is_ip[4/6]. Affected file is
1276 lib/silcutil/unix/silcunixnet.c. All routines that take
1277 address as argument now supports both IPv4 and IPv6 addresses.
1279 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1281 * Fixed LIST command reply sending in server. Affected file
1284 * Server now sends the kicker's client ID in the KICK notify
1285 to the kicked client. Affected file silcd/command.c.
1287 * The client library now parses the kickers client ID and
1288 UI displays it. Affected files lib/silcclient/client_notify.c
1289 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1291 * Made all payload parsing function prototypes consistent.
1292 They all take now const unsigned char * and uint32 pair as
1293 the payload data instead of SilcBuffer. Changes all around
1294 the source tree. Other unsigned char* -> const unsigned char*
1295 changes around the tree as well.
1297 * Optimized SFTP client and server packet sending not to
1298 allocate new buffer for each packet but to recycle the
1299 first allocated buffer. Affected files are
1300 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1302 * Optimized the SFTP client to use SilcList instead of
1303 SilcDList for requests, because it is faster. Affected file
1304 is lib/silcsftp/sftp_client.c.
1306 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1307 into lib/silccore/silcid.[ch].
1309 Renamed silcpayload.[ch] into silcargument.[ch].
1311 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * If client entry is deleted with active key agreement
1314 session, abort the session.
1316 The silc_client_abort_key_agreement now calls the completion
1317 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1319 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1322 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * Don't use __restrict in older GCC's. Affected file is
1325 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1327 * silc_net_localhost now attempts to reverse lookup the
1328 IP/hostname. Affected file lib/silcutil/silcnet.c.
1330 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1331 command. It can be used to gain founder privileges at
1332 the same time when joining the channel.
1334 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1335 kicker's client ID as well. Updated protocol specs.
1337 Defined that the server must send SILC_COMMAND_IDENTIFY
1338 command reply with error status to client who sent
1339 private message with invalid client ID.
1341 Updated the protocol specification.
1343 * Added silc_server_send_command_reply to send any
1344 command reply. Affected file silcd/packet_send.[ch].
1346 * Added silc_id_payload_encode_data to encode ID payload
1347 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1349 * The server now send IDENTIFY command reply with error
1350 status if client ID in private message is invalid. Affected
1351 file silcd/packet_receive.c.
1353 * Save the server key file with server's IP address in
1354 the filename instead of hostname. The affected file is
1355 irssi/src/silc/core/client_ops.c.
1357 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1359 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1362 * Added libtool support for compiling shared objects in
1363 lib/silcsim. Affected file configure.in.pre and
1364 lib/silcsim/Makefile.am. Original patch by cras.
1366 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Pid file configuration, and server's config file fixes
1369 patch by toma. Updated CREDITS file.
1371 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Fixed silc_client_channel_message to not try to decrypt
1374 the message twice if it resolved the destination client
1375 information. This could cause of dropping one channel
1376 message. Affected file lib/silcclient/client_channel.c.
1378 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1381 lib/silcclient/client.c. This function is used when the SILC
1382 Client is run under some other scheduler, or event loop or
1383 main loop. On GUI applications, for example this may be
1384 desired to used to run the client under the GUI application's
1385 main loop. Typically the GUI application would register an
1386 idle task that calls this function multiple times in a second
1387 to quickly process the SILC specific data.
1389 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1391 * Fixed silc_server_drop() for dropping the supplementary
1392 groups as well, this could cause a security hole on some
1395 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1397 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1400 * Write PID file after dropping privileges. Added -F option
1401 to run server on foreground. A patch by debolaz.
1402 Affected files silcd/server.c, silcd/silcd.c.
1404 * Fixed MOTD to return the MOTD file server name. Affected
1405 file silcd/command.c.
1407 * Added INFO command reply handling to the Irssi SILC Client.
1408 Affected file irssi/src/silc/core/client_ops.c.
1410 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Fixed the silc_idcache_list_* routines to really support
1413 the dynamic list. Fixes a crash. Affected file is
1414 lib/silccore/silcidcache.c.
1416 * Fixed the LIST command reply to really call LIST command's
1417 pending callbacks. Affected file silcd/command_reply.c.
1419 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Update conn->local_entry->nickname after giving NICK
1422 command. Affected file lib/silcclient/command.c.
1424 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1426 * Added the [pid] option to the silcd configuration file
1428 Affected files: serverconfig.[ch] and silcd.c
1430 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Save fingerprint in WHOIS command reply in server.
1433 Affected file silcd/command_reply.c.
1435 * Fixed NICK commands pending callback registration.
1436 Affected file lib/silcclient/command.c.
1438 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Use ++server->cmd_ident when sending commands in server,
1441 instead of random number. Affected file silcd/command.c.
1443 * Fixed GETKEY command reply to call actually GETKEY pending
1444 command callbacks. Affected file silcd/command_reply.c.
1446 * A bit stricter check for nicknames. Check for same nickname
1447 in NICK command also. Affected file silcd/command.c.
1449 * Do not call INFO command everytime client ID changes, only
1450 during first connecting. Affected file lib/silcclient/client.c.
1452 * Set the new nickname only after successful command reply for
1453 NICK command is returned by server. Affected file
1454 lib/silcclient/command.c.
1456 * Remove nicknames from nicklist during server_signoff notify.
1457 Should fix /NAMES bit more. The affected file is
1458 irssi/src/silc/core/silc-channels.c.
1460 * Added `fingerprint' field to the SilcIDListData in the
1461 silcd/idlist.h to hold the fingerprint of the client's
1464 Send the fingerprint of the client's public key in WHOIS
1467 Affected files silcd/command.c, and silcd/idlist.[ch].
1469 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1470 create fingerprint from given data.
1472 * Show the fingerprint of the client's public key in WHOIS.
1473 Affected files irssi/src/module-formats.[ch] and
1474 irssi/src/silc/core/client_ops.c.
1476 * Format the multiple same nicknames also during JOIN and
1477 NICK_CHANGE notifys. Affected file is
1478 lib/silcclient/client_notify.c.
1480 * Do not print error on screen for invalid private message
1481 payload since it can come if someone is sending private
1482 messages with wrong key. Affected file
1483 lib/silccore/silcprivate.c.
1485 * Fixed multiple concurrent /PING crash. Affected file
1486 lib/silcclient/command.c.
1488 * Changed the wrong ID encoding. All IP addresses must be
1489 in MSB first order in encoded format. They were encoded
1490 wrong and was in LSB format. Affected files are
1491 silcd/serverid.c, lib/silcutil/silcutil.c.
1493 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1495 * Call the `connect' client operation through the scheduler
1496 in case of error. Affected file lib/silcclient/client.c.
1498 * Call the `failure' client operation even if the error
1499 occurred locally during a protocol. Affected file is
1500 lib/silcclient/protocol.c.
1502 * Added support of sending LIST command to router from normal
1503 server. This way normal server can get list of all channels
1504 in the network too. Fixed the channel list sending in the
1505 server too. Affected files are silcd/command.c, and
1506 silcd/command_reply.[ch].
1508 * Added silc_server_update_channels_by_server and
1509 silc_server_remove_channels_by_server. They are used during
1510 disconnection of primary router and in backup router protocol.
1511 Affected file silcd/server_util.[ch], silcd/server.c and
1512 silcd/server_backup.c.
1514 * Fixed channel adding to global list in IDENTIFY command
1515 reply in server. Affected file silcd/command_reply.c.
1517 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * If the incoming packet type is REKEY or REKEY_DONE process
1520 that packet always synchronously. Fixes yet another MAC
1521 failed error on slow (dialup) connections. Affected file
1522 lib/silcclient/client.c and silcd/server.c.
1524 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1526 * Call check_version SKE callback for initiator too. Affected
1527 file lib/silcske/silcske.c.
1529 * Implemented fix for security hole found in the SKE that was
1530 fixed in the specification few days back; the initiator's
1531 public key is now added to the HASH value computation.
1532 Added backwards support for the old way of doing it too, for
1533 old clients and old servers. Affected file is
1534 lib/silcske/silcske.c.
1536 * Enabled mutual authentication by default in SKE. If initiator
1537 is not providing mutual authentication the responder will
1538 force it. This will provide the proof of posession of the
1539 private key for responder. The affected files are
1540 lib/silcclient/protocol.c and silcd/protocol.c.
1542 * Do not cache anymore the server's public key during SKE.
1543 We do mutual authentication so the proof of posession of
1544 private key is done, and if the server is authenticated in
1545 conn auth protocol with public key we must have the public
1546 key already. Affected file silcd/protocol.c.
1548 * Added new global debug variable: silc_debug_hexdump. If
1549 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1550 file lib/silcutil/silclog.[ch].
1552 * Fixed compilation warning due to char * -> const char *.
1553 Affected files lib/silcutil/silcnet.h, and
1554 lib/silccore/silcauth.[ch].
1556 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1558 * Fixed CMODE command when new channel key was created. If
1559 the creation failed the old key was removed. Next time giving
1560 same command would crash the server since the old key was
1561 freed already. Affected file silcd/command.c.
1563 * Fixed the silc_server_announce_get_channels to not crash
1564 on reconnect. Affected file silcd/server.c.
1566 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Added silc_log_set_debug_string function to set a regex
1569 string to match for debug output. Only the function names,
1570 or filenames matching the given debug string is actually
1571 printed. This way it is possible to filter out those debug
1572 strings that user is not interested in.
1574 Fixed a bug in silc_string_regexify.
1576 Affected files lib/silcutil/silclog.[ch], and
1577 lib/silcutil/unix/silcunixutil.c.
1579 * Changed the -d options in both server and Irssi SILC client
1580 to take the debug string as argument. Affected files
1581 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1583 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Added silc_hash_babbleprint to create a Bubble Babble
1586 Encoded fingerprint. The encoding is developed by Antti
1587 Huima (draft-huima-babble-01.txt), and it creates human
1588 readable strings out of binary data. Affected file
1589 lib/silccrypt/silchash.[ch].
1591 * Print the babble print now in addition of fingerprint as well
1592 in Irssi SILC client. Affected files are
1593 irssi/src/fe-common/silc/module-formats.[ch],
1594 irssi/src/fe-common/silc/core/client_ops.c.
1596 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Fixed a security problem found in SKE. The initiator's
1599 public key too is now added to the HASH hash value creation
1600 which is signed by the responder to create the SIGN value.
1601 This will prevent anyone in the middle to lie to the responder
1602 about the initiator's public key. If this is done now, the
1603 man in the middle will get caught. Updated the protocol
1606 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1608 * Better installation directory handling. Configure module
1609 paths and other paths automatically to example_silc* files
1610 in doc/. A patch by toma.
1612 * Fixed compiler warning from MPI library, and from SILC RNG.
1615 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1616 It can be configured with ./configure. A patch by toma.
1618 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Find correct make to use in prepare-clean. A patch by
1621 toma. Affected file prepare-clean.
1623 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1625 * Added irssi variables use_auto_addr, auto_bind_ip,

1640 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1642 * Added silc_pkcs_public_key_compare to compare two
1643 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1645 * Check that the client who set the founder mode on the
1646 channel is the same client that is giving the founder
1647 mode to itself. It is done by comparing the saved public
1648 key (it is saved even in the authentication is passphrase).

1656 * Process the DISCONNECT packet through scheduler in the
1657 client library. Affected file lib/silcclient/client.c.
1659 * Fixed the silc_client_packet_parse to not to increase
1660 the packet sequence number if the conn->sock and the
1661 current socket connection is not same. This can happen
1662 for example during key agreement when the conn includes
1663 multiple socket connections (listeners). Affected file
1664 lib/silcclient/client.c.
1666 * The sender of the file transfer request now provides also
1667 the pointer (listener) for the key exchange protocol. If
1668 the listener cannot be created then it sends empty key
1669 agreement and lets the receiver provide the listener.
1671 Added `local_ip' and `local_port' arguments to the
1672 silc_client_file_send. If they are provided they are used,
1673 if not then it will attempt to find local IP address, if
1674 not found or bind fails then the remote client will provide
1677 Affected files are lib/silcclient/client_ftp.c and
1678 lib/silcclient/silcapi.h.
1680 * Extended the FILE SEND command to support defining the
1681 local IP and port for key exchange listener. They are

1686 * Defined to WHOIS command reply the sending of fingerprint
1687 of the client's public key (if the proof of posession of the
1688 corresponding private key is verified by the server).
1689 Updated to the protocol specification.
1691 * Added support of receiving the client's public key's
1692 fingerprint in command reply in client library. Affected
1693 file is lib/silcclient/command_reply.c, and
1694 lib/silcclient/idlist.[ch].
1696 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1749 client library. Affected file lib/silcclient/client_prvmsg.c.
1751 * Do not actually remove the client directly from ID cache
1752 during SERVER_SIGNOFF, but invalidate it. This way we
1753 preserve the WHOWAS info for the client. Affected file
1754 silcd/server_util.c.
1756 * Fixed SERVER_SIGNOFF notify handling in the server. The
1757 server is now able to process incoming SERVER_SIGNOFF notify
1758 for a server that it doesn't even know about. It will remove
1759 the clients provided in the notify. Affected file
1760 silcd/packet_receive.c.
1762 * Check for partial packet in data queue after every packet that
1763 was found from the queue. Return and wait for more data if
1764 there is partial data in queue. Affected file is
1765 lib/silccore/silcpacket.c.
1767 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1782 irssi/src/fe-common/silc/module-formats.[ch].
1784 * Wrote a help file for FILE command.
1786 * Added silc_rng_global_get_byte_fast to get not-so-secure
1787 random data as fast as possible. Random data is read from
1788 /dev/urandom if available and from the SILC RNG if not
1789 available. It is used in padding generation. Affected file
1790 lib/silccrypt/silcrng.[ch].
1792 * All packets in client library are now processed synchronously.
1793 Optimized packet processing a lot. Affected file
1794 lib/silcclient/client.c.
1796 * All server connection packets are processing synchronously
1797 now in server, to optimize packet processing. Affected file
1800 * Include files are installed now only in Toolkit distribution
1801 if make install is given. Affected files: all Makefile.am's.
1803 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Assure that silc_client_notify_by_server_resolve does not
1806 resolve the client information multiple times. If it cannot
1807 be found by the first it cannot be found at all. Affected
1808 file lib/silcclient/client_notify.c.
1810 * Fixed WHOWAS command reply calling. Affected file
1811 lib/silcclient/command_reply.c.
1813 * Removed all references to silc_idlist_get_client from the
1814 Irssi SILC client since that call is internal call used by
1815 the library. The Irssi SILC client will use now client
1816 retrieval functions found in silcapi.h.
1818 * Fixed a bug in resolving nickname info before sending
1819 private message. It used freed memory. Affected file
1820 irssi/src/silc/core/silc-servers.c.

1841 * Added silc_net_localip to return local host's IP address.
1842 Affected file lib/silcutil/silcnet.[ch].
1844 * If key exchange or rekey protocol is active for a connection
1845 parse all packets syncronously since there might be packets
1846 in packet queue that we are not able to process without first
1847 processing packets before them. Affected file silcd/server,
1848 lib/silcclient/client.c.
1850 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1851 whether library should continue processing the packet.
1852 Affected file lib/silccore/silcpacket.h.

1898 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1899 is incomplete and is being resolved, it won't be resolved
1902 Make sure also that USERS command reply does not resolve
1903 twice information. Affected file is
1904 lib/silcclient/command_reply.c.
1906 Make sure that silc_client_get_clients_by_list does not
1907 resolve twice same information.
1909 * Check for valid client->id in the silc_server_free_client_data.
1910 Affected file silcd/server.c.
1912 * Fixed /GETKEY nick@server not to crash if the server entry
1913 is not found. Affected file lib/silcclient/command.c.

1925 * Call the silc_server_udpate_servers_by_server in the
1926 primary router that comes back online in the backup resuming
1927 protocol. Otherwise it routes packets wrong. Affected file
1928 silcd/server_util.[ch], silcd/server_backup.c.
1930 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1932 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1933 lib/silcutil/silcbuffmt.[ch].
1935 * Redefined the SILC packet header to include the padding
1936 length. Affected file lib/silccore/silcpacket.[ch].
1938 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1939 length for maximum padding up to 128 bytes). Affected
1940 file lib/silccore/silcpacket.h.
1942 * Removed all backwards support for old 0.5.x MAC thingies.
1943 The SILC packet header change makes it impossible to be
1944 backwards compatible.
1946 * Send the ENDING packet with timeout in the backup resuming
1947 protocol. This is to assure that all routers has connected
1948 to the primary router. Affected file silcd/server_backup.c.
1950 * Changed the RNG to take the first IV from random data. It
1951 used to take it from zero actually. Changed the RNG also
1952 to use /dev/urandom during session. /dev/random is used
1953 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1955 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1958 (the packet length) encrypted. Affected files aroung the
1959 code tree, lib/silccore/silcpacket.[ch]. Removed the
1960 SilcPacketCheckDecrypt callback. It is not needed anymore
1961 since the silc_packet_receive_process will determine now
1962 whether the packet is normal or special.
1964 * Implemented the unidirectional MAC keys. Affected files
1965 lib/silcske/silcske.c, silcd/protocol.c and

1973 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Allow backup router to announce servers. All servers
1976 announced by backup router are added to the global list
1977 automatically. Update hte server's socket to our primary
1978 router also when backup router announces a server.
1979 Affected file silcd/packet_receive.c.
1981 * Do not update the client->router in the function
1982 silc_server_udpate_clients_by_server if the client is on
1983 global list. We might fail to find any specific server
1984 for locally connected clients and local cell clients. They
1985 should still use the `from' and not `to' as client->router.
1986 This fixes backup router resuming protocol. Affected file
1987 silcd/server_util.c.
1989 * Decrease channel statistics count only if the channel
1990 deletion worked. Affected files are silcd/server.c and
1991 silcd/server_util.c.
1993 * Added silc_server_update_servers_by_server to update origin
1994 of all server entries. Used during backup router protocol.

2011 to the router it came from. Affected file is
2012 silcd/packet_send.c. Fixed memory leak too.
2014 * Announce informations for incoming router connection, but
2015 only after checking if it is replaced by backup router.
2016 Affected file silcd/packet_receive.c.
2018 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2021 router environment. Affected file silcd/server_backup.c.
2023 * Route packet only to one router in the function
2024 silc_server_packet_send_to_channel. Affected file is
2025 silcd/packet_send.c.
2027 * Fixed silc_server_send_notify_dest to set the broadcast
2028 flag. Fixed the silc_server_send_notify_topic to actually
2029 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2030 Affected file silcd/packet_send.c.
2032 * Changed the SFTP Filesystem interface. Changed the
2033 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2034 the filesystem operation function. The SilcSFTPFilesystem
2035 is now a context that is allocated by all filesystem allocation
2036 functions and it already includes the operations structure
2037 and filesystem specific context. It is given as argument
2038 now to the silc_sftp_server_start. This made the interface
2039 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2040 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2042 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Changed the backup router adding and getting interfaces
2045 in the server. The router that will be replaced by the
2046 specified backup router is now sent as argument. Affected

2099 send any data. Affected file lib/silcclient/client.c.
2101 * Implemented the backup router support when the primary router
2102 goes down. The servers and routers can now use the backup
2103 router as new primary router without loosing connectivity.

2107 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2108 in the server to indicate disabled entry. All data read
2109 from the connection will be ignored and no data is sent
2110 for entry that is disabled. Affected files are
2111 silcd/idlist.h, silcd/server.c.

2144 silc_buffer_set instead of allocating new buffer only for
2147 * Added 64-bit value formatting and unformatting support to the
2148 silc_buffer_[un]format routines. Affected file is
2149 lib/silcutil/silcbuffmt.[ch].
2151 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2152 to includes/bitmove.h.
2154 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Fixed channel user mode saving in client library. Affected
2157 file lib/silcclient/command[_reply].c.
2159 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Defined the file transfer to the SILC Protocol. Added
2162 new packet type SILC_PACKET_FTP and defined File Transfer
2163 Payload. The mandatory file transfer protocol is SFTP
2164 (SSH File Transfer Protocol). Affected file in addition
2165 of the internet draft is lib/silccore/silcpacket.h.
2167 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2168 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2169 is used as part of backup router protocol when the primary
2170 router of the cell is back online and wishes to resume
2171 the position as primary router.
2173 * Redefined the MAC generation keys in the protocol. The
2174 same key is not used anymore in both direction. Both
2175 direction will now use different keys for sending and
2176 receiving. This fixes a potential security flaw. This
2177 change causes incompatibilities in the protocol.
2179 * Redefined also the MAC computation from the packet.
2180 An packet sequence number is now added to the MAC
2181 computation. This prevents possible replay attacks against
2182 the protocol. This change too causes incompatibilities
2185 Added `sequence' field to the SilcPacketContext to hold
2186 the current sequence number for the packet.
2188 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Added `created' field to the SilcIDListData in the file
2191 silcd/idlist.h to indicate the time when the entry was
2194 * Added `created' field to the SilcChannelEntry too. Affected
2195 file silcd/idlist.h.
2197 * Added `creation_time' aguments to all the announcement functions
2198 in the server. If it is provided then only the entries that
2199 was created after the provided time frame are actually
2200 announced. Affected file silcd/server.[ch].
2202 * The protocol says that the Channel ID's IP address must be
2203 based on the router's IP address. Added check for this in
2204 the silc_server_new_channel when processing incoming New Channel
2205 Payload. Affected file silcd/packet_receive.c.
2207 * Print out the correct version with --version in SILC client.
2208 Affected file irssi/src/silc/core/silc-core.c.
2210 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Fixed WHOWAS command to check for completnes of the client
2213 entry always, not just when the command is coming from client.
2214 Affected file silcd/command.c.
2216 * Added new function silc_server_packet_queue_purge to purge the
2217 outgoing data queue to the network. After the function returns
2218 it is guaranteed that the outgoing packet queue is empty.
2219 Affected file silcd/packet_send.[ch].
2221 * Purge the outgoing packet queue in the rekey protocol's final
2222 callback to assure that all rekey packets go to the network
2223 before quitting the protocol. Affected file silcd/server.c.
2225 * Added silc_client_packet_queue_parse as similar function as
2226 in server to the client library. The affected file is
2227 lib/silcclient/client.c.
2229 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Splitted silcd/server.c and created silcd/server_util.[ch]
2232 for utility functions.
2234 * Added new socket flag SILC_SF_DISABLED to indicate that the
2235 connection is open but nothing can be sent to or received from
2236 the connection. Affected file lib/silcutil/silsockconn.[ch].
2237 The checking for disabled socket is checked in the low level
2238 silc_socket_write and silc_socket_read functions.
2240 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Allow only nicknames and channel names that fits into the
2243 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2245 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * When processing JOIN command reply in server check that if
2248 the channel exists in our global list we'll move it the local
2249 list. Affected file silcd/command_reply.c.
2251 * Fixed the check whether client is joined on the channel already
2252 in JOIN command. Affected file lib/silcclient/command.c.
2254 * Fixed the JOIN command reply to check whether the channel
2255 already exists. Affected file lib/silcclient/command_reply.c.
2257 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2259 * Added silc_ske_status_string to map the SKE error numbers
2260 to readable strings. The affected files are
2261 lib/silcske/silcske[_status].[ch].
2263 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Do not show the private channels on the WHOIS channel list
2266 as it is not allowed by the protocol. The affected file is
2269 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Assure that the packet length digged from the actual packet
2272 is something sensible in the silc_packet_decrypt_rest_special
2273 in lib/silccrypt/silcpacket.c.
2275 * Free and NULL the allocated pointer in silc_hmac_alloc if
2276 the HMAC allocation fails. The affected file is
2277 lib/silccrypt/silchmac.c.
2279 * Print the selected security properties to the log files in
2280 the server. Affected file silcd/protocol.c.
2282 * Add SKE's reference counter even if calling the completion
2283 callback manually. Otherwise it goes negative, although it
2284 does not cause any problems. The affected file is
2285 lib/silcske/silcske.c.
2287 * Remove the client entry with short timeout after giving the
2288 KILL command. Affected file lib/silcclient/command.c.
2290 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2291 case all found clients are already disconnected (WHOWAS would
2292 found them) in the server. Affected file silcd/command.c.
2294 * Update the last_receive (time of last data received) to be
2295 updated only when received private or channel message so that
2296 the idle time showed in WHOIS makes more sense.
2298 * Added boolean field `valid' in to the SilcClientEntry in the
2299 client library to indicate whether the entry is valid or not.
2300 This fixes the nickname change bug on channel when changing
2301 the nickname to be same than the old (like nick to Nick) the
2302 nickname formatter doesn't set the new nick anymore to Nick@host.
2303 Affected file lib/silcclient/idlist.[ch].
2305 * Now actually fixed the nickname changing on disconnection.
2306 Added new function silc_change_nick to the Irssi SILC Client.
2307 Affected file irssi/src/silc/core/client_ops.c,
2308 irssi/src/silc/core/silc-nicklist.[ch].
2310 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Check that the public key exists in the GETKEY command before
2313 trying to encode it. Affected file silcd/command.c.
2315 * Print some notifications on received public keys with GETKEY
2316 command in the Irssi SILC Client. Affected files are
2317 irssi/src/fe-common/silc/module-formats.[ch],
2318 irssi/src/silc/core/client_ops.c.
2320 * Use IDENTIFY command to resolve the server information in the
2321 GETKEY command instead of INFO command. Affected file
2322 lib/silcclient/command.c.
2324 * All command reply functions in the client library now calls
2325 the pending command reply callbacks even if an error has
2326 occurred. The server has done this a long time and now it was
2327 time to move the client library to this as well. Now all
2328 errors can be delivered back to the pending command reply
2329 callbacks if necessary. Affected files are
2330 lib/silcclient/command[_reply].[ch].
2332 * Change the nickname on disconnection back to the username
2333 because in reconnect the server will enforce it to it anyway.
2334 Affected file irssi/src/silc/core/silc-servers.c.
2336 * Fixed a config file parsing bug in the Irssi SILC client.
2337 Affected file irssi/src/silc/core/clientconfig.c.
2339 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * When printing the channel mode on JOIN, verify that the
2342 channel key and channel's HMAC are valid. Affected file
2343 irssi/src/silc/core/client_ops.c.
2345 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2348 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2349 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2351 * Removed channel key rekey task deleting from the function
2352 silc_server_save_channel_key. Affected file silcd/server.c.
2353 Added explicit timeout task context instead that is used to
2354 delete the task if we are registering a new task before the
2355 new task has elapsed.
2357 * When channel key rekey occurs the client library now saves
2358 the old channel key for a short period of time (10 seconds) and
2359 is able to use it in case some is still sending channel
2360 messages encrypted with the old key after the rekey. Affected
2361 file lib/silcclient/[idlist.h|client_channel.c].
2363 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added check to the silc_server_new_id_real to not accept
2366 new ID if it is the sender's own ID. Affected file is
2367 silcd/packet_receive.c.
2369 * Assure that we do not announce ourself or the one we've
2370 sending our announcements when we're router and are announcing
2371 servers to our primary router. Affected file silcd/server.c.
2373 * Fixed silc_server_command_identify_check_client to assemble
2374 correct WHOIS packet. It send corrupted WHOIS packet and
2375 caused problem with router to router connections. Affected
2376 file silcd/command.c.
2378 Fixed also silc_server_command_whois_check the same way
2379 as for the IDENTIFY command.
2381 * Added new SilcIDListStatus to the server in the SilcIDListData
2382 structure. The status now includes the current status of
2383 the entry (like registered, resolved etc.). Affected file
2384 silcd/idlist.[ch]. Defined a bunch of different status types
2385 as well. This replaced the old boolean registered field as well.
2387 Added resolve_cmd_ident field to the SilcClientEntry structure
2388 too so that if the entry is for example being resolved so
2389 another command may attach to the same pending command reply
2390 without requiring to resolve the same entry again. This concept
2391 should optimize the WHOIS and the IDENTIFY resolving under
2392 heavy load by taking away unnecessary resolving for entries
2393 that are being resolved already.
2395 Added support for adding multiple pending commands for one
2396 command idenfier. Affected file silcd/command[_reply].[ch].
2398 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2399 before deleting the data. Otherwise the hash table will have
2400 freed data in comparison functions. Affected file is
2401 silcd/command_reply.c.
2403 * Fixed silc_idlist_replace_client_id to add the new entry to
2404 the cache with NULL nickname. Otherwise there will be invalid
2405 memory as the nickname after the nickname is freed. Affected
2406 file silcd/packet_receive.c.
2408 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2409 saved into wrong slots because the previous number of entries
2410 was not taken into account. Affected file silcd/idlist.c.
2411 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2413 * If we are router and we receive JOIN notify to a channel that
2414 does not have any users then notified client is marked as the
2415 channel founder, as it is it. The affected file is
2416 silcd/packet_receive.c
2418 * Added to the extended hash table API's table_del_*ext functions
2419 the destructor as argument too, so that the caller can decide
2420 which destructor to use or whether to use destructor at all.
2421 Affected file lib/silcutil/silchashtable.[ch].
2423 * Fixed ID Cache purging. It actually deleted the entries from
2424 the hash table after the data was freed. The hash table ended
2425 up comparing freed memory. The affected file is
2426 lib/silccore/silcidcache.c.
2428 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Fixed Irssi SILC client's KILL command's HELP syntax.
2432 * The USERS command now resolves the detailed user information
2433 if the userinfo field is missing. Affected file is
2434 lib/silcclient/command_reply.c.
2436 * Do not print error in silc_file_read if the read file does
2437 not exist. Just silently return NULL. Affected file is
2438 lib/silcutil/silcutil.c.
2440 * Fixed the silc_log_output to not wine about NULL filename
2441 and to not create some bogus " " filename. Affected file is
2442 lib/silcutil/silclog.c.
2444 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Fixed various printing bugs on the user interface in the
2447 Irssi SILC Client. Minor changes that were forgotten from
2450 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Fixed the configure.in.pre and the compilation and distribution
2453 environment to support the new autoconf 2.52. That version is
2454 now required to compile the CVS trunk.
2456 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2459 to generally parse user@fqdn format strings. Affected file
2460 lib/silcutil/silcutil.c.
2462 * Added nickname_format and nickname_force_format fields to the
2463 SilcClientParams structure. The first one defines the format
2464 for the nicknames that the library will enforce if the receives
2465 multiple same nicknames. The second one is boolean value and
2466 can be used to force the library to always enforce the format
2467 to the nicknames regardles whether there are multiple nicknames
2468 or not. This configurable formatting was employed to flexibly
2469 support accessing multiple nicknames from the user interface.
2470 The userinterface can now set the nicknames to what ever format
2471 they prefer. Affected file lib/silcclient/silcapi.h.
2473 Added function silc_client_nickname_format to the file
2474 lib/silcclient/idlist.c. It performs the nickname formatting.
2476 Added new field `hostname´ to the SilcClientEntry context.
2477 It holds the hostname of the client. Affected file is
2478 lib/silcclient/idlist.h.
2480 * Irssi SILC Client sets the nicknames in nick@hostn format.
2481 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2482 irssi/src/silc/core/silc-core.c.
2484 The WHOIS printing now also shows both the real nickname and
2485 the formatted nickname so that user knows how to access the
2486 user if there are multiple same nicknames cached. Affected
2487 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2488 printing formatting too to take the hostname now as a separate
2489 argument. The Affected file is
2490 irssi/src/fe-common/silc/modules-formats.[ch].
2492 * Changed the silc_client_get_clients_local to accept the formatted
2493 nickname as argument. It accepts the real nickname too but the
2494 formatted nickname can be used to find the true entry from
2495 multiple entries. Affected file lib/silcclient/silcapi.h and
2496 lib/silcclient/idlist.c.
2498 * Added nickname_format_parse field to the SilcClientParams.
2499 It is a callback function provided by the application to parse
2500 the nickname out of the formatted nickname string. The library
2501 calls it to get the nickname from the formatted string. Since
2502 the application generally knows better the format of the nickname
2503 string it parses it instead of the library, even though library
2504 encodes the formatted string. If the callback function is not
2505 provided then the library will use the string as is. The
2506 affected file is lib/silcclient/silcapi.h.
2508 * All the nickname strings passed to the client library in
2509 commands are now expected to be formatted nickname strings.
2510 If the command does not support the formatted nickname string
2511 it will assume that the sent string is the actual nickname.
2512 Affected file lib/silcclient/command.c.
2514 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Added public key authentication support to OPER and SILCOPER
2517 commands in the client library. Affected file is
2518 lib/silcclient/command.c.
2520 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2522 * Changed the get_auth_methdod client operation to be asynchronous.
2523 It can be async if the application resolves the authentication
2524 method from the server during the negotiation. Added new
2525 SilcGetAuthMeth completion callback that the application will
2526 call after resolving the authentication method.
2528 Added function silc_client_request_authentication_method that
2529 the application can use to resolve the authentication method
2530 from the server. Added also SilcConnectionAuthRequest callback
2531 that the library will call after the server has replied. The
2532 application can call this function if it does not know the
2533 current authentication method.
2535 Affected files are lib/silcclient/client.c and
2536 lib/silcclient/silcapi.h.
2538 * The Irssi SILC client now automatically resolves the authentication
2539 method incase any configuration information is not present (and
2540 currently there never is). The affected file is
2541 irssi/src/silc/core/client_ops.c.
2543 * Fixed public key authentication from the client library.
2544 Affected file lib/silcclient/protocol.c. Changed also the
2545 protocol specification about the public key authentication in
2546 the connection authentication protocol. The actual data to be
2547 signed is now computed with a hash function before signing.
2549 * Fixed the public key authentication from the server as well.
2550 Affected file silcd/protocol.c.
2552 * Removed the mlock()'s from the memory allocation routines.
2553 Affected file lib/silcutil/silcmemory.c. The ./configure does
2554 not check anymore for the mlock(). Affected file is
2557 * Fixed USERS command in server to allow the execution of the
2558 command for private and secret channels if the client sending
2559 the command is on the channel. Affected file silcd/command.c.
2561 * Fixed silc_client_get_clients_local to return the clients
2562 count correctly. It could return wrong value. Affected file
2563 lib/silcclient/idlist.c.
2565 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2568 types. The assembler optimizations seemed not to like 64-bit
2569 data types. The assmebler optimizations thus are now enabled
2570 also for BSD systems as opposed to only enable them for Linux.
2572 * Do not check for threads at all on BSD systems. Affected
2573 file configure.in.pre.
2575 * Removed -n and -h options from the Irssi SILC Client since
2576 they are not used in silc.
2578 * Fixed the prime generation to assure that the first digit
2579 of the generated random number is not zero since our conversion
2580 routines does not like number strings that starts with zero
2581 digit. If zero digit is seen the random number is regenerated.
2582 This caused some corrupted RSA keys when the zero first digit
2583 was met. Affected file lib/silcmath/silcprimegen.c.
2585 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Fixed WIN32 configuration in the ./configure script.
2588 Fixed to include xti.h on environments that has it.
2589 Patches by Carsten Ilchmann and andrew.
2591 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Changed the silc_id_create_client_id to be collision
2594 resistant. It is now assured that there cannot be created
2595 two same client ID's. I suspect that some weird bugs in
2596 the server were actually caused by duplicate Client IDs.
2597 Affected file silcd/serverid.[ch]. A router receiving
2598 new ID now also assures and informs the sending server
2599 if the ID caused collision.
2601 * Changed the silc_id_create_channel_id to also assure that
2602 there are no collisions.
2604 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Statement about ignoring the Mutual Authentication flag when
2607 performing rekey with PFS was a bit misleading. It is ignored
2608 if it was set in the initial negotiation, it cannot be even
2609 set in the rekey. Fixed in the ke-auth draft. Started the
2610 new versions of the protocol drafts in the doc/.
2612 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Fixed a bug in silc_client_command_identify_save when saving
2615 new channel information. The channel name was no duplicated
2616 and caused crash on exit. Affected file is
2617 lib/silcclient/command_reply.c.
2619 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Fixed the getkey command handling in the server. Send just
2622 empty OK reply to the sender if the key could not be fetched
2623 (but everything else was ok, like the key just was not available).
2624 Changed the public key parameter to optional in the protocol
2625 specs so that empty OK reply can be sent. Affected file
2628 Added a message to Irssi SILC client to tell to user if the
2629 server did not return a public key.
2631 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Fixed a channel key regeneration bug. It registered new
2634 timeout tasks exponentially until all system resources were
2635 used. Affected file silcd/server.c.
2637 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Added the SILC Document generator to the scripts/silcdoc.
2640 It can be used to generate the Toolkit Reference Manual out
2641 of the source tree. Internally it will also use the RoboDoc
2642 generator now imported in util/robodoc.
2644 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Added couple of return's in rekey protocol if error orccurred
2647 during the protocol. The execution must be terminated.
2648 Affected file silcd/protocol.c. Also, terminate the protocol
2649 always with timeout.
2651 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2653 * The client's Client ID was created initally from the wrong
2654 nickname (it could have been in format nick@host) in the
2655 silc_server_new_client. Affected file silcd/packet_receive.c
2657 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Added some SILC_LOG_ERROR's to various error conditions
2660 if client could not be added to ID cache. Affected files
2661 silcd/packet_receive.c and silcd/server.c.
2663 * When client's sock->user_data is freed, NULL also the
2664 client->router and client->connection pointers. Added check
2665 for these pointers being NULL to various places around the
2666 code. Affected file silcd/server.c.
2668 * Added client->data.registered == TRUE checks to various
2669 places around the code to assure that unregistered client's
2670 are not handled when it is not allowed. Affected file
2673 * Added `bool registered' fields to all
2674 silc_idlist_[server|client]_get_* routines to indicate whether
2675 the fetched client needs to be registered or not. Affected
2676 file silcd/idlist.[ch].
2678 * Add your own entry as registered to the ID cache in the
2679 server. Affected file server.c.
2681 * Fixed a bug in silc_server_new_server. The SilcServer was
2682 set as the new server's context instead of SilcServerEntry.
2683 This naturally caused some weird bugs.
2685 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Do not delete the channel rekey task when adding it
2688 for in silc_server_create_channel_key.
2690 * Changed the silc_server_create_channel_key to return
2691 TRUE or FALSE to indicate the success of the channel key
2694 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Fixed MSVC++ project files and added missing files to
2697 Makefiles under win32/.
2699 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2701 * Do not add TCP_NODELAY flag if the operating system
2702 does not have it defined. Affected files are
2703 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2705 * Fixed buffer overflow from Irssi SILC Client. Affected
2706 file irssi/src/fe-common/core/themes.c.
2708 * Fixed double free in client library in the file
2709 lib/silcclient/client.c when disconnecting from server.
2711 * Applied double free patch from cras to Irssi SILC client.
2712 Affected files irssi/src/core/[modules/expandos].c
2714 * Fixed the disconnection handling to Irssi SILC Client.
2715 The application must call silc_client_close_connection
2716 in ops->connect client operation in case of failure of
2717 the connection. Affected file is
2718 irssi/src/silc/core/client_ops.c.
2720 * Do not set sock->protocol to NULL in the function
2721 silc_client_close_connection after executing the protocol's
2722 final callback since the sock might not be valid anymore.
2723 Affected file lib/silcclient/client.c.
2725 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Do not enable SILC_THREADS if the linking with libpthread
2728 did not happen. Affected file configure.in.pre.
2730 * Added notion to protocol specification that server must
2731 verify the sent authentication payload with CMODE when
2732 setting the channel founder key. Implemented it to the
2733 server. Affected file silcd/command.c.
2735 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Added _EXTRA_DIST SILC distribution variable to the
2738 distributions file. It is used to conditionally add extra
2739 files or directories to the specific distribution. Affected
2740 files ./prepare, Makefile.am.pre and distributions.
2742 Removed the `_' from the start of the distribution names.
2745 * Added README.WIN32 for instructions to compile the Toolkit
2748 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * Fixed a double free in disconnection in the server. Affected
2751 file is silcd/server.c.
2753 * Fixed the lib/silcske/groups.c to work now also with GMP
2754 MP library. The string conversion did not work when using
2755 specific base and the base is indicated in the string as well.
2757 * Created win32/ directory which now includes MSVC++ specific
2758 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2759 It will appear only in the toolkit distribution
2761 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Changed the key material distribution function in case when
2764 the hash output is too short. The data is now concatenated
2765 a bit differently than it used to. Made the change to the
2766 SKE protocol specification.
2768 * Added better GMP detection to configure.in.pre. A patch
2771 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Fixed a minor bug in SKE that might cause some problem on
2774 some platforms. Affected file lib/silcske/silcske.c.
2776 * Added the cookie checking for initiator in the SKE. It checks
2777 that the responder returns the sent cookie unmodified. The
2778 affected file is lib/silcske/silcske.c. Added new SKE
2779 error type INVALID_COOKIE that can be sent during the
2780 negotiation. Fixed some memory leaks as well.
2782 * Added the "invalid cookie" error message to Irssi SILC client's
2785 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Added `task_max' field to the SilcClientParams to indicate
2788 the maximum tasks the scheduler can handle. If set to zero,
2789 default values are used. Affected file lib/silcclient/silcapi.h.
2791 * Fixed memory leaks in silc_client_close_connection. Affected
2792 file lib/silcclient/client.c.
2794 * Added silc_client_del_client_entry to client library to free
2795 all memory of given client entry. Affected file is
2796 lib/silcclient/idlist.[ch].
2798 * Added new functions silc_client_del_channel and
2799 silc_client_del_server to delete channel and server entries.
2800 Affected file lib/silcclient/[silcapi.h/idlist.c].
2802 * Removed silc_client_del_client_by_id from silcapi.h.
2804 * Fixed the INFO command to return the server's own info
2805 correctly when querying by Server ID. Affected file is
2808 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Removed the non-blocking settings in WIN32 code in the
2811 silc_sock_[read/write] and added SleepEx instead. Affected
2812 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2813 of input data is now checked with FIONREAD and ioctlsocket.
2815 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * Call silc_schedule_task_del_by_context in the
2818 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2819 Affected file lib/silccore/silcprotocol.c.
2821 * Call silc_protocol_cancel for active protocols in the
2822 silc_server_close_connection if the funtion
2823 silc_server_free_sock_user_data has not been called.
2824 Affected file silcd/server.c.
2826 * Generic tasks cannot be deleted using the del_by_fd
2827 task deleting function since generic tasks does not match
2828 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2830 * Added a notion to SILCOPER help file that the SILCOPER works
2831 only on router server, not on normal server.
2833 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Added for WIN32 support for the new scheduler as well.
2836 Affected file lib/silcutil/win32/silcwin32schedule.c.
2838 * Fixed the SHA1 implementation to work on various platforms.
2840 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2843 API. It is part of the scheduler now. Everything else is
2844 as previously but some functions has changed their names.
2845 Checkout the lib/silcutil/silcschedule.h for the interface.
2846 Updated all applications to use the new interface. Affected
2847 files are lib/silcutil/silcschedule.[ch].
2849 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Found a bug in the SKE implementation. The HASH value,
2852 specified by the protocol, was not computed correctly. The
2853 public key of the responder was not added to the computation
2854 even though it is mandatory. Affected file lib/silcske/silcske.c.
2855 This unfortunately causes incompatibilities with older
2856 clients and servers.
2858 * Added WIN32 specific network init and uninit functions:
2859 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2860 the Winsock2. Affected file lib/silcutil/silcnet.h and
2861 lib/silcutil/win32/silcwin32net.c.
2863 * Set the socket always to nonblocking mode on WIN32 after
2864 reading data or writing data. Affected file is
2865 lib/silcutil/win32/silcwin32sockconn.c.
2867 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * Fixed various compilation problems under WIN32. Affected
2870 files lib/silcutil/win32/silcwin32thread.c and
2871 lib/silcutil/win32/silcwin32schedule.c.
2873 * Removed all _internal.h #includes from public header
2874 files. Internal headers must never be included from
2877 Removed also the lib/silcske/payload_internal.h file.
2879 * All include files that may be needed (public and some others
2880 included by the public headers) by application developers are
2881 now copied to the ./includes directory. It does not copy any
2882 internal headers. Affected file Makefile.defines.pre and all
2883 Makefile.am's under lib/ and subdirs.
2885 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Do not change the ~/.silc directory's permissions automatically.
2888 Affected file irssi/src/silc/core/clientutil.c.
2890 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Do not cancel the protocol in silc_server_close_connection
2893 it might cause recursion. Now cancelled in the function
2894 silc_server_free_sock_user_data. Affected file silcd/server.c.
2896 * Fixed the silc_server_remove_clients_by_server to regenerate
2897 the channel keys correctly finally. Added also new function
2898 silc_server_remove_clients_channels to actually do it.
2899 Affected file silcd/server.c.
2901 * Fixed the silc_server_new_channel to not crash by giving
2902 wrong router to the new channel. Affected file is
2903 silcd/packet_receive.c.
2905 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2908 which is given as argument to the silc_client_alloc now.
2909 It can be used to configure the client and set various parameters
2910 that affect the function of the client.
2912 * The USERS command in server did not check whether the channel
2913 is private or secret. Affected file silcd/command.c.
2915 * Added new argument to the USERS command in protocol specification.
2916 The USERS command now can take the channel name as argument
2917 as well. Added support for this in client and server and
2918 updated the protocol specs.
2920 * Completed the GETKEY command in client. It can be now used
2921 to fetch also servers public key not only some clients.
2922 Affected files lib/silcclient/command[_reply].c.
2924 * Added silc_client_get_server to return server entry by the
2925 server name. Affected files lib/silcclient/silcapi.h and
2928 * Redefined the IDENTIFY command in protocol specification to be
2929 more generic. It now can be used to query information about
2930 any entity in the SILC Network, including clients, servers and
2931 channels. The query may be based either the entity's name
2932 or the ID. Added support for this in both client and server.
2934 Affected files silcd/command.c and lib/silcclient/command.c
2935 and command_reply.c.
2937 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2938 the _from_client and _from_server functions. Affected file
2941 * Added silc_client_get_channel_by_id_resolve to the file
2942 lib/silcclient/silcapi.h to resolve channel information by
2943 its ID. Added also silc_client_get_channel_by_id that
2944 does not resolve it from the server.
2946 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Added SilcServerEntry context into the client library
2949 to represent one server. The INFO command now allocates
2950 these to save the resolved server info. For now on the
2951 client library will also keep information about servers,
2952 connected and resolved with INFO.
2954 The INFO command now allocates the SilcServerEntry context
2955 and saves the server info there. The COMMAND_REPLY in
2956 the INFO now returns the parameters to application in
2957 same order as defined in the protocol specification.
2959 The entries are cached in the client->server_cache.
2961 * The INFO command is now issued after received the Client ID
2962 from the server. Affected file lib/silcclient/client.c.
2964 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2965 to the application as the mode changer might be server.
2966 It is guaranteed that NULL is not returned anymore to the
2967 application. Affected file lib/silcclient/client_notify.c.
2969 The ID Type is now also passed to the application so that
2970 it can check whether the returned entry is SilcClientEntry
2973 Added new function silc_client_get_server_by_id to return
2974 the server entry by ID. Affected files are the
2975 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2977 * Do not create the channel in the Irssi SILC Client when issuing
2978 the JOIN command but when received the sucessful JOIN command
2979 reply. Otherwise the channel might get created even though we
2980 could not join it. The Affected file is
2981 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2983 * Fixed a channel joining bug in router. The router must also
2984 check the channel modes, invite and ban lists etc. when serving
2985 the JOIN command sent by normal server. Affected file is
2986 silcd/command.c. The router now resolves the client's
2987 information from the server who sent the JOIN command if it
2988 does not know it, and processes the JOIN command only after
2991 * Changed the SilcCommandCb to take new argument; void *context2.
2992 Affected file lib/silccore/silccommand.h
2994 The second argument in the command callbacks in the server now
2995 includes the SilcServerCommandReplyContext if the command was
2996 called as pending command callback from the command reply.
2997 Otherwise it is NULL. When called as pending the status of the
2998 command reply will be checked and if it was erronous the
2999 error will be sent to the original sender of the command.
3000 This way the client always receives the error messages even
3001 though the server was actually the one who received the error
3002 when it resent the command to router, for example. Affected
3003 files silcd/command[_reply].[ch].
3005 * Fixed sending WHOWAS command's error message to client if
3006 the requested client could not be found. It was missing.
3009 * Changed the CMODE and CUMODE commands reply arguments in the
3010 protocol specification. The Channel ID is now sent in both
3011 of the commands to identify the channel. Implemented this
3012 new feature to the client and server. Affected files
3013 lib/silcclient/command_reply.c and silcd/command.c.
3015 * Made better checks for invite and ban lists in the JOIN
3016 command in server. Affected file silcd/command.c.
3018 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * The server now performs the incoming host IP/DNS lookup
3021 using the silc_socket_host_lookup and thus does not block
3022 the server anymore. Affected file silcd/server.c.
3024 * Completed the multi-thread support for SILC Scheduler in
3025 the lib/silcutil/silcschedule.c.
3027 * Fixed the configure.in.pre to detect the pthread correctly
3030 * Fixed a deadlock in silc_task_queue_wakeup in the file
3031 lib/silcutil/silctask.c.
3033 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Added new function silc_schedule_wakeup that is used in
3036 multi-threaded environment to wakeup the main thread's
3037 schduler. It needs to be used when a thread adds a new task
3038 or removes a task from task queues. After waking up, the
3039 scheduler will detect the task queue changes. If threads
3040 support is not compiled in this function has no effect.
3041 Implemented the wakeup mechanism to both Unix and WIN32
3042 systems. Affected files are lib/silcutil/silcschedule.[ch],
3043 lib/silcutil/unix/silcunixschedule.c and the
3044 lib/silcutil/win32/silcwin32schedule.c.
3046 * Added new function silc_task_queue_wakeup to wakeup the
3047 scheduler by the specified task queue. Affected file
3048 lib/silcutil/silctask.[ch].
3050 * The silc_socket_host_lookup_start now wakes up the scheduler
3051 after adding the timeout task. Affected file is
3052 lib/silcutil/silcsockconn.c.
3054 * The silc_socket_host_lookup is synchronous now if the threads
3055 support is not compiled in. However, the callback is still
3056 called asyncronously through the scheduler, anyway. Affected
3057 file lib/silcutil/silcsockconn.c.
3059 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Added new function silc_socket_host_lookup to perform
3062 asynchronous IP and FQDN lookups for the socket connection.
3063 Affected files lib/silcutil/silcsockconn.[ch].
3065 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3068 that may or may not compile the mutex support in.
3070 Changed the silc_mutex_alloc interface. It allocates the
3071 mutex now to the sent pointer and returns TRUE or FALSE.
3073 Affected file lib/silcutil/silcmutex.h.
3075 * Wrote the SILC Task Queue interface to support multi-threads.
3076 Affected file lib/silcutil/silctask.[ch].
3078 * Wrote the SILC Scheduler to support multi-threads. Affected
3079 file lib/silcutil/silcschedule.c.
3081 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3084 in lib/silcutil/win32/.
3086 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Defined SILC Mutex API and SILC Thread API and implemented
3089 them for Unix. Affected files are
3090 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3091 lib/silcutil/unix/silcunixmutex.c and
3092 lib/silcutil/unix/silcunixthread.c.
3094 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3096 * Fixed the silc_server_remove_clients_by_server's channel
3097 key re-generation. The hash table handling was incorrect
3098 and would not work with many channels. Affected file is
3101 * Fixed some memory leaks around the server code.
3103 * Rewrote the silc_server_get_users_on_channel to support IPv6
3104 based Client ID's. Affected file silcd/server.c.
3106 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3107 specification. However, a separate document must be written
3108 to define the detailed signing procedure and the payload
3109 associated with the flag. Defined the flag to the
3110 lib/silccore/silcchannel.h as well.
3112 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Changed the dynamic tables to static size tables in the
3115 lib/silccrypt/silchmac.c.
3117 * Removed GCC dependencies from the code. A patch by cras.
3119 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Do not show the error "Error receiving packet bla bla"
3122 in server if it really was not an error (-2 means that reading
3123 is pending). Affected file silcd/server.c.
3125 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Fixed a possible crash in silc_server_remove_clients_by_server
3128 in silcd/server.c. Fixed there also some memory leaks.
3130 * Fixed the silc_idlist_replace_client_id. It could replace
3131 wrong key in the hash table. Affected file silcd/idlist.c.
3133 * Do not check whether there are global users on the channel
3134 if the channel->global_users is FALSE. Affected functions
3135 silc_server_remove_from_one_channel and
3136 silc_server_remove_from_channels in silcd/server.c. Also,
3137 do not check if the removed client is local as we can be
3138 sure that global client was not removed from the channel
3139 and checking for global users is not needed.
3141 * The silc_server_remove_clients_by_server now re-generates
3142 the channel keys correctly for those channels that had
3143 clients removed from them. Affected file silcd/server.c.
3145 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Found the reason of random crashes in the server. We weren't
3148 ignoring the SIGPIPE signal (which can be sent in write())
3149 and it crashed the server. Affected file silcd/silcd.c.
3151 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Assure that sock->user_data is not NULL in the function
3154 silc_server_packet_send in silcd/packet_send.c.
3156 * Disconnect the remote connection if it could not be added
3157 to any ID lists in the server. The affected file is
3160 * Check in silc_server_packet_send[_real/dest] that the
3161 socket is not disconnecting and ignore the data if it is.
3162 Affected file silcd/packet_send.c.
3164 * Define inline to __inline on native WIN32 compilation.
3165 Affected file includes/silcwin32.h.
3167 * Added some explicit type casts for inline code since MSVC
3168 require them. Affected files lib/silcutil/silcbuffer.h,
3169 lib/trq/silcdlist.h and lib/trq/silclist.h.
3171 * Print warning in log files from now on if the packet
3172 decryption fails. Affected file silcd/server.c.
3174 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Changed the `say' client operation's interface to accept
3177 new `type' argument to indicate the type of the message sent
3178 by the library. The application may filter the library's
3179 messages according the type. The affected file is the
3180 lib/silcclient/silcapi.h.
3182 * Added two new functions to lib/silcclient/silcapi.h:
3183 silc_client_del_client and silc_client_del_client_by_id.
3184 Affected file lib/silcclient/idlist.c.
3186 * Moved the clientincludes.h from includes/ to silc/ and
3187 serverincludes.h from includes/ to silcd/.
3189 * The modes for the CMODE and CUMODE are now passed as
3190 uint32 for application with COMMAND_REPLY. The affected
3191 file is lib/silcclient/command_reply.c.
3193 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3195 * /WHOIS without arguments shows client's own information.
3196 Affected file lib/silcclient/command.c.
3198 * Changed PING to not accept any arguments. The specs
3199 says that client can ping only the connected server so
3200 requiring an argument is not needed. Affected file is
3201 lib/silcclient/command.c.
3203 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Fixed a fatal bug in private message sending and reception
3206 encryption and decryption when using private message keys.
3207 The implementation was incorrect and did not follow the
3208 specification. It causd that some of the message were
3209 lost since it did not use the sending and receiving keys
3210 as the protocol suggests. This has been fixed and will cause
3211 incompatibilities with older clients when sending private
3212 message encrypted with private message keys. Affected files
3213 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3214 and various other in Irssi SILC Client.
3216 Added `responder' boolean argument to the functions
3217 silc_client_add_private_message_key[_ske] to indicate when
3218 the key is added as responder or initiator of the key
3221 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Removed the silc_ske_check_version function and created
3224 a SilcSKECheckVersion callback. Added also a function
3225 silc_ske_set_callbacks that is now used to set all SKE
3226 callbacks. The callback functions are not given to
3227 the SKE functions anymore, but this function is used to
3230 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3232 * Added `silc_version' argument to the silc_client_alloc
3233 to define the version of the application for the library.
3234 The library will use the version string to compare it
3235 against the remote host's (usually a server) version
3236 string. Affected file lib/silcclient/silcapi.h
3238 * Added the KE protocol context to Key Agreement context
3239 in client library so that we can abort the SKE if it
3240 is in process when we get timeout. Affected file is
3241 lib/silcclient/client_keyagr.c.
3243 * Do not resolve the client ID forever if it returns in the
3244 first time that such client does not exist. This was done
3245 for example with private message. Affected file is
3246 lib/silcclient/client_prvmsg.c.
3248 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * Do not add regex.h for WIN32. The affected file
3251 includes/silcincludes.h.
3253 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3254 not work yet 100%. It generates the DLL's automatically
3255 when compiling with --with-win32 under cygwin.
3257 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * lib/contrib/regex.c is not compiled on WIN32.
3261 * Added silc_net_get_socket_opt function to the
3262 lib/silcutil/silcnet.h.
3264 * Added includes/silcwin32.h for WIN32 specific includes
3267 * Do not use ptime structure or any of the posix process
3268 functions on WIN32 in lib/silccrypt/silrng.c.
3270 * Added silc_gettimeofday to provide generic function
3271 for struct timeval on all platforms. Added the function
3272 to lib/silcutil/silcutil.h.
3274 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3277 library as they clearly belong there. As a plus side we
3278 can make the actual socket connection routines platform
3281 Added also new generic function silc_socket_read and
3282 silc_socket_write (that used to be silc_packet_[read/write].
3283 The implementation of these are platform specific.
3285 * Added WIN32 specific routines of silc_socket_[read/write]
3286 to lib/silcutil/win32/silcwin32sockconn.c.
3288 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Added preliminary support for native WIN32 compilation under
3291 cygwin (using the -mno-cygwin option for GCC) to the
3292 ./configure.in.pre. The --with-win32 now prepares the
3293 compilation for native WIN32.
3295 * Rewrote the SILC Scheduler interface in the file
3296 lib/silcutil/silcschedule.h. The scheduler is now context
3297 based and does not have anymore any global static scheduler.
3298 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3299 and created lib/silcutil/win32 directory for WIN32 based
3302 * Added Unix specific network routines to the
3303 lib/silcutil/unix/silcunixnet.c and the old
3304 lib/silcutil/silcnet.c includes now only generic routines.
3306 Added WIN32 specific network routines to the
3307 lib/silcutil/win32/silcwin32net.c.
3309 * Added Unix specific utility functions from the
3310 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3312 * Added WIN32 SILC Scheduler to the file
3313 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3316 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Do not handle JOIN notify in the server if the target client
3319 is not registered (idata->registered == FALSE). The affected
3320 file is silcd/packet_receive.c.
3322 * Update the nickrec->founder in event_cumode in the Irssi SILC
3323 client. Affected file irssi/src/silc/core/silc-channels.c.
3325 * Fixed the CUMODE_CHANGE notify handling in the server when
3326 server and router are announcing their clients on channels.
3327 Now the mode changes are saved and notified correctly. The
3328 affected file is /silcd/packet_receive.c.
3330 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3331 They really did not replace the cache entry in the ID Cache.
3332 Now they do that. Affected file silcd/idlist.c.
3334 * Fixed the KICK notify handling in the Irssi SILC client to
3335 update the channel records so that the kicked client does not
3336 appear to be on the channel. The affected file is
3337 irssi/src/silc/core/silc-channels.c.
3339 * Always update the conn->current_channel when executing command
3340 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3342 * Fixed the KILL notify handling in Irssi SILC client to remove
3343 the killed client on all channels.
3345 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Fixed the silc_parse_command_line to remove extra spaces
3348 from the start and end of the arguments. Affected file is
3349 lib/silcutil/silcutil.c.
3351 * Cancel and free any active protocol in the function
3352 silc_server_close_connection. Affected file silcd/server.c.
3354 * Cancel and free any active protocol in the function
3355 silc_client_close_connction. Affected file is
3356 lib/silcclient/client.c.
3358 * Do not execute the KILL command for clients that are in
3359 history (ie. they are not in the network). Affected file is
3362 * Fixed KILL notify handling, client does not crash anymore.
3363 Affected file irssi/src/silc/core/silc-channels.c.
3365 * Reduced the default packet buffer size from 2048 to 1024 in
3366 lib/silccore/silcpacket.c.
3368 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3369 counter to the SKE context that is incresed when the SKE library
3370 performs async operation outside the library. If the outside
3371 process frees the SKE context and FREED status will be set
3372 and the library will detect after the sync operation that the
3373 libary is freed. The affected files are
3374 lib/silcske/silcske[_status].[ch].
3376 * Resolve the client entry information in the function
3377 silc_client_channel_message to assure that NULL pointer is not
3378 passed as client entry to the application. */
3380 * Fixed the task timeout calculation to assure that there is
3381 never negative timeouts. The affected file is
3382 lib/silcutil/silcschedule.c.
3384 * Fixed the channel user mode notification sending in server.
3385 It was sent point-to-point to the router (or to server by router)
3386 but it needs to be destined to a channel. The routines now
3387 supports sending the channel user mode notifys to the channels
3388 when announcing clients and channels. Affected files are
3389 silcd/server.c and silcd/packet_receive.c.
3391 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3392 It did not actually replace the old channel entry in the cache.
3393 Affected file lib/silcclient/client_notify.c.
3395 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Fixed a possible crash in silc_packet_send_prepare. It now
3398 assures always that there is enough space in the buffer and
3399 at the tail area of the buffer (for MAC).
3401 Fixed the inbound buffer reallocation in silc_packet_read.
3402 It was old code and did not handle the reallocation correctly.
3405 The affected file is lib/silccore/silcpacket.c.
3407 * Fixed buffer overflow in silc_parse_nickname in the file
3408 lib/silcutil/silcutil.c.
3410 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * make install generates new server keys only if there is not
3415 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3418 Added check that if the NOREPLY is set then we will not send
3419 the away message. This avoids infinite loop of away messages
3420 if both clients are away. The affected file is
3421 lib/silcclient/client_prvmsg.c.
3423 * Fixed client crash if /NICK was given without arguments.
3424 Affected file lib/silcclient/command.c.
3426 * Server does not send the invite list in INVITE command back
3427 to the client if the list was not altered. Added this notion
3428 to the protocol spec as well. Affected file silcd/command.c.
3430 Fixed possible crash in INVITE command by checking the
3431 value of silc_server_get_client_route command.
3433 * Fixed the INVITE notify type handling. The arguments are now
3434 taken in correct order and client does not crash. The affected
3435 file is irssi/src/silc/core/silc-channels.c.
3437 Removed the "Inviting xxx to channel" message from the
3438 client library away and let the application handle it.
3439 Affected file lib/silcclient/command.c. Added that message
3440 to Irssi SILC client's message formats.
3442 * Fixed CMODE command crash in client. It now checks the
3443 amount of arguments correctly and does not crash. The affected
3444 file is lib/silcclient/command.c.
3446 * Do not create new channel automatically in silc_channels_join
3447 but check whether the channel by that name already exists.
3448 Affected file irssi/silc/core/silc-channels.c.
3450 * Do not send the SERVER_SIGNOFF to router if the disconnected
3451 entity was the router. Affected file silcd/server.c.
3453 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3454 SILC client as it was missing from there.
3456 Added the handling of the KICK notify to the Irssi SILC client
3457 as it was missing. Added "you have been kicked" message to
3458 Irssi SILC client's message modules formats.
3460 Added the handing of the KILL notify to the Irssi SILC client
3461 as it was missing. Added the kill message module formats
3464 The affected file is irssi/src/silc/core/silc-channels.c.
3466 * The router did not save the channel mode the server announced.
3467 Affected file silcd/packet_receive.c.
3469 * Fixed a possible crash in INFO command in server. If the
3470 server did not provide the server info it crashed. Affected
3471 file silcd/command.c.
3473 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Fixed the GETKEY command in the server to check also the
3476 global list. Otherwise the GETKEY would not work correctly
3477 in normal SILC server. Affected file silcd/command.c.
3479 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Fixed GETKEY crash, it crashed if the command did not succseed.
3483 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3486 is now real and not just an macro interface to GMP.
3488 Removed the entire GMP from the source tree and imported new
3489 NSS MPI library instead. Reason for removing GMP is that it is
3490 extremely large and compiles extremely slow. The NSS MPI
3491 is only a few files and compiles in less than 10 seconds.
3492 The speed is also about the same as GMP. The MPI is imported
3493 to lib/silcmath/mpi.
3495 If the system has GMP installed we will still use the GMP.
3496 If it is not then the NSS MPI will be compiled.
3498 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Merged a long nickname (127 characters long) crash bugfix from
3501 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3503 * Merged a freed memory reference bugfix from Irssi CVS tree.
3504 Affected file irssi/src/core/commands.c.
3506 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Added the server's public key sving and verification to the
3509 server when performing the SKE. This was missing and the
3510 remote server's (or router's) public key was accepted without
3511 checking whether we have it previously or trust it at all.
3512 Affected file silcd/protocol.c.
3514 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Check in the silc_server_timeout_remote if protocol is active
3517 and make sure that the protocol's final callback is called so
3518 that all memory if freed. Affected file silcd/server.c.
3520 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * silc_server_whois_send_reply crashed the server if the nickname
3523 was 127 characters long. Affected file silcd/command.c.
3525 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Added sanity check to the silc_server_new_client. If the hostname
3528 is provided inside username then check that the provided hostname
3529 really is the same as the resolved one. If the hostname was not
3530 resolved then check it from the public key. Affected file is
3531 silcd/packet_receive.c.
3533 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3534 if the server disconnected us and the connection is not valid
3535 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3537 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3538 the library to the lib/silcutil/silcutil.[ch].
3540 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Close log file after open. Affected file
3543 lib/silcutil/silclog.c.
3545 * Check whether sock == NULL in silc_client_send_packet and return
3546 if it is. Affected file lib/silcclient/silcclient.c.
3548 * Check rec->entry == NULL in the Irssi SILC Client before
3549 sending the channel message. Affecte file is
3550 irssi/src/silc/core/silc-servers.c.
3552 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Merged a splitted window bugfix from Irssi CVS tree. The
3555 affected file is irssi/src/fe-text/textbuffer-view.c.
3557 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3558 It did not print nickname.
3560 * Improved the distributions system a bit.
3562 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3565 irssi/src/fe-text/gui-window.c.
3567 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3568 to in-active server. The affected file is
3569 irssi/src/silc/core/client_ops.c.
3571 * Resolve the client in USERS command reply if the entry does
3572 not have username resolved. The affected file is
3573 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3574 command to WHOIS command to really resolve stuff. The USERS
3575 is not used any more in any critical section so WHOIS can
3576 be used even though it might be slower than IDENTIFY.
3578 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3581 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3583 * Changed the protocol API a bit more consistent in the
3584 lib/silccore/silcprotocol.[ch].
3586 * Changed the following headers to ROBODoc format:
3588 lib/silccore/silcpayload.h
3589 lib/silccore/silcprotocol.h
3590 lib/silccore/silcsockconn.h
3592 All core library headers are now formatted.
3594 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Fixed a bug in Irssi SILC client; do not show that you are
3597 server/router operator if you really are not. Affected file is
3598 irssi/src/silc/core/client_ops.c.
3600 * Renamed silc_command_free_payload to silc_command_payload_free.
3601 Affected file lib/silccore/silccommand.h
3603 * Added silcmath.h to include the prototoypes of various routines
3604 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3607 * Changed the following headers to ROBODoc format:
3609 lib/silccore/silcchannel.h
3610 lib/silccore/silccommand.h
3611 lib/silccore/silcid.h
3612 lib/silccore/silcidcache.h
3613 lib/silccore/silcmode.h
3614 lib/silccore/silcnotify.h
3615 lib/silccore/silcpacket.h
3616 lib/silcmath/silcmath.h
3618 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Added checking to the server code not to start the server if
3621 ciphers and stuff are not configured properly. Affected files
3622 silcd/serverconfig.[h] and silcd/server.c.
3624 * Changed the layout of the header files of the public interfaces
3625 in the SILC libraries. The new layout supports ROBODoc
3626 documentation tool (and some others) so that it is easy to create
3627 a library reference manual. All the other headers and source
3628 code must still follow the CodingStyle document. Also source
3629 code must not include these ROBODoc stuffs, only the headers.
3630 Furthermore, all public interface headers must now be named
3631 by using `silc' prefix, example: silcapi.h, silccipher.h.
3632 Some files were renamed due to this. All the other headers
3633 must not be used as public interfaces. I will update the
3634 CodingStyle document later. Changed following headers, so far:
3636 lib/silcclient/silcapi.h
3637 lib/silccore/silcauth.h
3638 lib/silccore/silcprivate.h
3639 lib/silccrypt/silcdh.h
3641 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Removed silc_client_packet_send_flush from the client library
3646 as it is not needed. Affected file lib/silcclient/client.[ch].
3648 * Added printing of message of unresolved authentication method
3649 to the Irssi SILC client. Added it to the module formats.
3650 Removed the same message from the client library.
3652 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Added new distribution feature, DISTLABEL. Every distribution
3655 can define own preprocessor label that can be used in the
3656 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3657 file distributions, acconfig.h.pre and prepare.
3659 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Added Makefile.defines_int to include the actual definitions
3662 for Makefile.defines.in. Tested the new distribution system,
3663 created distributions and tested installation.
3665 * Added AWAY message printing to the Irssi SILC client. Added
3666 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3668 * Added SCONNECT command to call the SILC's CONNECT command.
3669 Cannot use CONNECT directly since Irssi uses that internally.
3670 Affected file irssi/src/silc/core/silc-servers.c.
3672 Added ACTION local command. It is same as ME command but takes
3673 the channel as mandatory argument.
3675 Rewrote some of the Irssi's help files to suite for SILC
3678 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3680 * Added Makefile.defines[.in] that should for now on be included
3681 in all Makefile.am file in the source tree. That file includes
3682 all common compilation definitions for SILC source tree.
3684 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Minor changes to the ./prepare script to change the package
3687 name according the distribution name to the configure.in.
3689 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Created new distribution system. Added file `distributions'
3692 that defines all the distributions that can be created out of
3693 the SILC source tree. The ./prepare script now reads that
3694 file to determine how to prepare the distributions. The
3695 first argument to the ./prepare is the name of the distribution
3696 and second is the version of the distribution. If given
3697 without arguments it creates the default (toolkit) distribution
3698 with the default version (defined in ./prepare).
3700 All Makefile.am files that are subject to the distributions
3701 are now named as Makefile.am.pre. These are ./Makefile.am
3702 and lib/Makefile.am. Others may be changed later.
3704 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Added invite list, ban list, some key management and connection
3707 error message printing to module formats in the Irssi SILC client.
3709 * Added new silc_client_set_away_message to set the away message
3710 that is back to the person who sent private message. The
3711 affected file lib/silcclient/silcapi.h and the
3712 lib/silcclient/client_prvmsg.c.
3714 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed the private message sending in the Irssi SILC client,
3717 added local command KEY to the Irssi SILC client.
3719 Added key management and key agreement message formats to the
3720 irssi/src/fe-common/silc/module-formats.[ch].
3722 Added USERS (alias WHO) printing, server/router operator
3723 indication and LIST command printing to the module formats.
3725 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Fixed channel joining notify handling, cumode notify handling
3728 from Irssi SILC client.
3730 * Added SILC specific module-formats to the Irssi SILC client so
3731 that SILC specific message hilighting, colors etc is possible.
3732 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3734 Added channel mode, channel user mode, actions, notices,
3735 whois and whowas printing to the the module-formats.c.
3737 * Fixed a bug in channel deletion in the server. The channel
3738 is not left to the cache even if the channel founder auth mode
3739 is set when there are no users anymore on the channel. Affected
3740 file silcd/server.c.
3742 * The silc_net_localhost now resolves the entire hostname including
3743 the domain name. Affected file lib/silcutil/silcnet.c.
3745 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Changed the ask_passphrase client operation to be ascynchronous.
3748 It has now a completion callback and a context that the
3749 application must call after it has got the passphrase from
3750 the user. Affected files lib/silcclient/silcapi.h,
3751 lib/silcclient/protocol.c, lib/silcclient/command.c and
3754 Added SilcAskPassphrase callback that the application calls
3755 to deliver the passphrase to the library.
3757 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3758 The public key verification and especially a certificate
3759 verification is asynchronous procedure.
3761 Added new SILC_SKE_STATUS_PENDING status to indicate the
3762 request is pending and a callback will be called to finalize
3765 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3766 indicate that remote end did not send its public key (or
3767 certificate), even though we require it. Added check for this
3768 condition in the SKE. This was a security bug, now fixed.
3770 Defined new SilcSKEVerifyCbCompletion callback that is called
3771 when the verification process is completed.
3773 The affected files lib/silcske/silcske_status.h and
3774 lib/silcske/silcske.[ch].
3776 * Changed the verify_public_key client operation to be async
3777 as well. Defined SilcVerifyPublicKey callback that is used to
3778 indicate the success of the public key verification process.
3780 Changed the server and client to use the new async client
3783 * Changed the Irssi SILC client's internal scheduler to be called
3784 twice as many times as it used to be. As a result the client
3785 should be a bit faster now. Affected file is
3786 irssi/src/silc/core/silc-core.c.
3788 * Added support to Irssi SILC client of asynchronous public key
3789 verification and passphrase inquiry. Affected file is
3790 irssi/src/silc/core/silc-core.c.
3792 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Do not say "You have left channel %s" in client library.
3795 Moved it to the application. Affected files are
3796 lib/silcclient/command.c and silc/client_ops.c.
3798 * Fixed silc_client_get_clients. Command context was not
3799 duplicated and was freed memory in the callback. Affected
3800 file lib/silcclient/idlist.c.
3802 * Do not say "you are now talking..." on JOIN command in the
3803 client library. The appliation must handle it.
3805 * Do not say ".. changed topic to" in command reply in the
3806 client libary. The application must handle it.
3808 * Fixed TOPIC command sending in the client library.
3810 * Fixed a memory leak in silc_client_command_free in the file
3811 lib/silcclient/command.c.
3813 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Imported a modified version of Irssi client to the source tree.
3816 The Irssi will be used to create a new client called
3817 Irssi SILC. Imported to irssi/.
3819 Added silc_core_init_finish function to the Irssi. Affected
3820 file irssi/configure.in.
3822 A lot changes in the Makefile.ams around the irssi tree.
3824 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Do not rehash if the new size is same as the old size of the
3827 hash table, in the silc_hash_table_rehash*. The affected file
3828 lib/silcutil/silchashtable.c.
3830 * Replaced hash_table_del_by_context calls from the server
3831 (when channel->user_list and client->channels) to the
3832 hash_table_del as it is sufficient and faster.
3834 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Added silc_hash_table_list, silc_hash_table_get and the
3837 SilcHashTableList structure to provide an alternative way to
3838 traverse the hash table. The affected files are
3839 lib/silcutil/silchashtable.[ch].
3841 * Changed the server's idlist routines to use the hash table
3842 routines to optimize the code.
3844 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Replaced the client entry's `channel' list and channel entry's
3847 `user_list' list to hash tables for optimized lookup. Changed
3848 the code to use the hash table interface around the code.
3849 Affected file lib/silcd/idlist.[ch].
3851 * Added `auto_rehash' boolean argument to the function
3852 silc_hash_table_alloc to indicate whether the hash table should
3853 auto-rehash when it thinks is appropriate time. It will
3854 increase the hash table size if the there is twice as much
3855 entries in the table than the size of the table, and will
3856 decrease the size if there are twice as less entries than
3857 the size of the table.
3859 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3863 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3865 * silc_idcache_purge_by_context deletes the entry now by context
3866 as it is supposed to do. Affected file lib/silccore/idcache.c.
3868 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3869 client is not anymore valid (WHOWAS givens the info) and not
3870 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3872 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3874 * Removed the `data' and `data_len' arguments from the ID Cache
3875 interfaces and added `name' argument. ID Cache does not handle
3876 anymore the binary data only a names associated with given ID.
3878 * When hashing a Client ID with silc_hash_id the entire ID is
3879 not hashed anymore, instead only the hash of the Client ID is
3880 hashed. This way we can access the Client ID from the cache
3881 with Client ID but with the hash of the ID (which is a hash of
3882 the nickname) as well without any difference in performance.
3884 Added also silc_idcache_find_by_id_one_ext to do one on one
3885 searching when we have the actual ID. Added also function
3886 silc_hash_client_id_compare. The affected files are
3887 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3889 * When hashing the name associated with a ID it is always done
3890 in lowercase. This way we can access the cache without worrying
3891 about case-sensitivity, even though, for example nicknames are
3894 * Fixed a bug in server with channel message sending. It put
3895 wrong ID type as destination ID. The affected file
3896 silcd/packet_send.c.
3898 * silc_idcache_del_by_context now deletes from all hash tables
3899 by context. Affected file lib/silccore/idcache.c.
3901 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Changed the client library to use the new ID Cache interface.
3904 Changes around the source tree.
3906 * Added silc_hash_table_rehash_ext to rehash with specific
3907 hash function. Affected file lib/silcutil/silchashtable.[ch].
3909 * Added silc_hash_string_compare to compare two strings in the
3910 hash table. Affected file lib/silcutil/silcutil.[ch].
3912 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Added new function silc_idcache_del_by_context into the
3915 lib/silccore/idcache.[ch].
3917 * Changed the server's ID list routines to use the new ID Cache
3918 interface. Changes around the source tree.
3920 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Added silc_hash_table_del[_by_context]_ext functions in to the
3923 lib/silcutil/silchashtable.[ch].
3925 Removed silc_hash_table_find_all* routines and added new
3926 silc_hash_table_find_foreach to replace them.
3928 Added silc_hash_table_replace_ext function as extended
3929 replacing function. Separated the simple hash table interface
3930 from the extended hash table interface in the file
3931 lib/silcutil/silchashtable.h.
3933 * Fixed minor bugs and changed it to use some of the new
3934 hash table functions in lib/silccore/idcache.c
3936 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added new function silc_hash_table_find_all to return all keys
3939 in the hash table by the specified key. As the hash table is
3940 collision resistant it also makes it possible to have several
3941 duplicate keys in the hash table. This function may be used to
3942 find all of the keys from the hash.
3944 Added user_context arguments to the SilcHashFunction,
3945 SilcHashCompare and SilcHashDestructor to deliver user specified
3948 Added new fuctions silc_hash_table_find[_all]_ext to do
3949 extended lookup with specified hash and compare functions and
3950 specified user contexts.
3952 Added new function silc_hash_table_add_ext to add the key
3953 with specified hash function and user context.
3955 Added new function silc_hash_table_foreach to traverse all
3956 entrys in the hash table. Added SilcHashForeach callback
3959 Added new function silc_hash_table_del_by_context to delete
3960 the entry only if the context associated with the key matches.
3962 Affected files are lib/silcutil/silchashtable.[ch].
3964 * Removed silc_hash_[server/client/channel]_id and added just
3965 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3966 silc_hash_id_compare to compare two ID's using as the hash table
3967 comparison function. Added also silc_hash_data to hash
3968 binary data and silc_hash_data_compare to compare it.
3970 * Removed silc_idlist_find_client_by_hash as it is not needed
3971 anymore. Affected file silcd/idlist.[ch].
3973 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3974 to use internally the SilcHashTable. The new ID Cache is a lot
3975 faster than the old one. Some of the ID Cache interface was also
3976 rewritten and obsolete and stupid functions were removed.
3978 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Added entry_count field to the SilcHashTable to keep the number
3981 of the entries in the table. Implemented the function
3982 silc_hash_table_rehash. Added new function
3983 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3985 Fixed a minor bug in silc_hash_table_free.
3987 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3988 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3989 into the lib/silcutil/silcutil.[ch].
3991 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Implemented a collision resistant hash table into the
3994 lib/silcutil/silchashtable[ch]. See the header and the source
3995 for the SilcHashTable API.
3997 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Merged dotconf version 1.0.2 into lib/dotconf.
4001 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Do not compile anything in lib/silcsim/* if the SIM support
4004 is not enabled. The tree should now compile without problems
4007 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Compiled the SILC under cygwin. Compiled and tested briefly
4010 without problems. More tests needed. The SIMs didn't compile
4013 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4015 * Fixed possible crash in silc_get_username in the
4016 lib/silcutil/silcutil.c.
4018 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Fixed a va_arg in silc/client_ops.c.
4022 * Oops, RC5 routines were named AES and caused some problems
4023 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4025 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Added new SilcIDIP structure into the lib/silccore/id.h and
4028 replaced the old `ip' fields from all SILC ID's to that type.
4029 This is a step towards IPv6 support.
4031 The silc_id_get_len takes now the ID as an extra argument.
4032 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4033 both IPv4 and IPv6 based ID's.
4035 The affected files are lib/silccore/id.[ch] and other files
4036 around the tree using these routines.
4038 * Removed the ID length arguments in server from various
4039 silc_server_send_notify_* routines -> they are not needed
4042 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Fixed memory leak in silc_encode_pem_file in the file
4045 lib/silcutil/silcutil.c.
4047 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Check minor version as well in the SKE. Affected files are
4050 silcd/protocol.c and lib/silcclient/protocol.c.
4052 * Added --identifier option to the server so that an identifier
4053 can be when creating the public key for the server. Affected
4054 file is silcd/silcd.c.
4056 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4057 lib/silccrypt/silcpkcs.c.
4059 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Register default ciphers and stuff when using -C option with
4062 the server. Affected file sildc/silcd.c.
4064 * Put back the servers public key filename format, it is better
4065 than the new one. For now, the client keys are saved with the
4066 new filename format. The affected file silc/client_ops.c.
4068 * Implemented the Cipher API for the rest of the ciphers that
4069 did not implement it or implemented it the wrong way.
4071 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Register default ciphers and stuff when using the -S option
4074 in the client. Affected file silc/silc.c. Same also when
4075 creating new key pair with -C option.
4077 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed the silc_verify_public_key client operation function to
4080 save the public keys differently. The fingerprint is now
4081 used as filename and not the hostname. This way also the
4082 client keys are saved uniquely and not with hostnames. The
4083 affected file is silc/client_ops.c.
4085 * Trimmed the silc_hash_fingerprint function to remove extra
4086 whitespaces from the end of the fingerprint. The affected
4087 file is lib/silccrypt/silchash.c.
4091 * Added silc_cipher_register_default function to register all
4092 default ciphers. It can be used when configuration files
4093 does not exist and the application does not want any specific
4094 ciphers in any specific order.
4096 The SilcDList is now used as silc_cipher_list dynamically
4097 allocated cipher list. Removed the static list all together
4098 and now all ciphers must be allocated to the dynamic list.
4099 The silc_cipher_alloc routine was changed to check only the
4102 All silc_cipher_* routines that used to return int returns
4105 The affected files lib/silccrypt/silccrypt.[ch].
4107 * The same thing was done to silc_hash_* as for silc_cipher_*
4108 routines. Affected files lib/silccrypt/silchash.[ch].
4110 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4111 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4112 Added also silc_pkcs_[un]register[_default] functions.
4113 Removed the data_context from the PKCS API.
4115 * Added silc_hmac_register_default function to register default
4116 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4117 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4118 to unregister all hmacs at once.
4120 * Register the default ciphers, hash functions, PKCSs and HMACs
4121 if client's configuration file does not exist. The affected
4124 * The client did not load the hash functions from the SIM
4125 modules at all. Added support for this. Affected file is
4126 silc/clientconfig.c.
4128 * When decoding public key with silc_pkcs_public_key_decode, check
4129 the supported algorithm only if PKCS are registered. Affected
4130 file lib/silccrypt/silcpkcs.c. The same was done with the
4131 silc_pkcs_private_key_decode.
4133 * Fixed the SILC List routines to keep the list always in order.
4134 It used to change the list's order when traversing the list but
4135 not it preserves the order. Affected file lib/trq/silclist.h.
4137 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Added the client library to use the SilcSocketConnection's
4140 reference counter (by silc_socket_dup) to prevent the bug that
4141 the socket object may be freed underneath async operation.
4143 * The name resolv library checking fixes in the configure.in.pre.
4146 * Created new version of the protocol drafts for future
4147 development. The -03 drafts are the ones that will be changed
4148 in the trunk now and the -02 will remain as they are.
4150 * Send list of CUMODE notifys to the router when announcing
4151 the channel users to the router. Affected file silcd/server.c.
4152 If the router receiving channel founder CUMODE for a channel
4153 that already has channel founder it will send CUMODE notify
4154 to the sender to remove the channel founder rights from the
4155 announced client. Affected file silcd/packet_receive.c.
4157 * The CUMODE notify may now use Server ID as well as the entity
4158 who changes the mode. Updated protocool specs.
4160 * Updated INSTALL and README files.
4162 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * New web pages in the http://silc.pspt.fi. The pages was
4169 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Implemented the [DenyConnectin] config section in the server.
4172 Added silc_server_config_denied_conn to check whether incoming
4173 connection is denied. Affected file silcd/serverconfig.[ch].
4175 * Do not check the ports when checking the incoming configuration
4176 data if the port is 0, meaning any. Affected file is
4177 silcd/serverconfig.c.
4179 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Fixed buffer overflow in silc_string_compare in the file
4182 lib/silcutil/silcutil.c.
4184 * Fixed double free in silc_server_command_leave in the file
4187 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Fixed the version checking in the server. Affected file is
4192 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Fixed the configuration data fetching when accepting new
4195 connections in the server. Affected file silcd/server.c.
4197 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Added `sender_entry' argument to the function
4200 silc_server_packet_relay_to_channel so that we can check
4201 whether some destination actually belongs to the same route
4202 the sender belongs (ie, we must not resend the packet to the
4203 sender). Affected file silcd/packet_send.[ch].
4205 * Added `servername' field to the SilcClientEntry in the server
4206 to hold the name of the server where client is from. Affected
4207 file is silcd/idlist.h.
4209 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Moved the channel message encrypting in the router betwen
4212 router connections from silc_server_channel_message to the
4213 silc_server_packet_relay_to_channel since we want to check
4214 whether we have anybody channel before encrypting anything.
4215 Affected files silcd/packet_[receive/send].c.
4217 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Fixed the [AdminConnection] server config section to support
4220 multiple entries. Affected file silcd/serverconfig.c.
4222 * Added support into the server to check the validity of the
4223 incoming connection before executing any KE or authentication
4226 * The connection configuration is now saved to the KE and
4227 connection auth protocol contexts and not fetched anymore in
4228 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4230 * The local hosts listenning address and port is also resolved
4231 now when starting the server. We want to have the socket object
4232 to include the real address and port for the listener. Added
4233 new function silc_net_check_local_by_sock into the files
4234 lib/silcutil/silcnet.[ch].
4236 * Fixed a broadcast bug in server -> do not broadcast if we
4239 * Fixed a routing bug. Do not route broadcast packets ever.
4240 Broadcast packets must be processed always and not routed since
4241 they may be destined to some other host than yourself and thus
4242 would get routed without no good reason. Affected file is
4245 * Added function silc_server_config_is_primary_route to check
4246 whether primary router connection has been configured (a router
4247 configuration that we are initiating). If there is not, we
4248 will assume that there is only two routers in the SILC network
4249 and we will use the incoming router connection as our primary
4250 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4252 * Changed the order of the broadcasting. Broadcast _after_ the
4253 packet has been processed not before. Affected file is
4256 * Fixed a [ClientConnection] parsing bug. The port was never
4257 parsed correctly thus resulting to port 0. Affected file
4258 silcd/serverconfig.c.
4260 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4261 argument and did not set the broadcast packet flag. Affected
4262 file silcd/packet_send.c. Fixed same bug in the function
4263 silc_server_send_notify as well.
4265 * If we receive NEW_ID packet for our own ID in the server, ignore
4268 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Removed the nickname from the Private Message Payload.
4273 Updated the code and the protocol specs.
4275 * Updated protocol specs for submitting to the IETF.
4277 * Tweaked the Random Number Generator a bit. Affected file
4278 lib/silccrypt/silcrng.c. Exported a new function
4279 silc_rng_[global]_add_noise which can be used to add more
4282 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Do not parse packets with different timeout when protocol
4285 is active -> may cause problem with rekey. Affected file
4288 * When server receives signoff notify it must not create
4289 new channel key if the client is on any channels since the
4290 sender of the signoff notify will create it.
4292 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Added printing of error messages during SKE protocol from the
4295 failure packet sent by server during SKE. Affected file
4298 * Removed the client's failure_callback handling with timeout
4299 and handle it immediately when received.
4301 * The SKE library returned wrong type in SUCCESS and FAILURE
4302 packets. They must be 32 bit MSB not 16 bit MSB.
4304 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Ok, rewrote the logic of the re-key and now it seems to work.
4307 I tested it on high traffic with frequent re-keys without
4308 problems. Added hmac_receive (and renamed hmac to hmac_send)
4309 in SilcClientConnection in lib/silcclient/client.h and
4310 in SilcIDListData in silcd/idlist.h. Also, removed the
4311 SilcPacketParserContext's cipher and hmac fields as they are
4312 not needed anymore and actually caused some problems when
4313 the ciphers and hmac's changed underneath the packet parser.
4315 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * If re-key protocol is active then process the incoming packets
4318 synchronously since we must assure that icoming packets encrypted
4319 with the old key is processed before the new keys is set to
4320 use. This is true other packets than for REKEY packets.
4321 Affected file silcd/server.c. The same was done to client library
4322 as well, affected file lib/silcclient/client.c.
4324 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Fixed bug in client and server to accept the force send if
4327 the packet is send from silc_[server/client]_packet_process
4328 function. Otherwise the packets are never delivered, oops.
4330 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Disable force sending of packets when REKEY protocol is active.
4333 We must assure that no packet is sent directly when rekey is
4334 performed. All packets must be sent through packet queue.
4335 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4336 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4337 function is silc_[server/client]_packet_send_real to check
4340 * Replaced the SIM paths from example config files to
4341 /usr/local/modules. Also, make install creates now
4342 /usr/local/silc/logs directory to hold all the SILC server
4345 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Made the configure.in.pre work on Solaris. Patch by salo.
4349 * Made all ciphers compatible with non-x86 machines. Defined
4350 CBC mode macros into lib/silccrypt/ciphers_def.h.
4352 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Fixed the make install.
4356 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * When MAC computation fails the silc_packet_decrypt returned 0
4359 even though it was supposed to return -1. Fixed this. The
4360 affected file is lib/silccore/silcpacket.c.
4362 * Do not replace the config files in /etc/silc (in make install)
4363 if they already exist. Affected file ./Makefile.am.
4365 * Do not send re-key packets immediately but through packet queue.
4366 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4368 * Changed silc_net_check_host_by_sock to return FALSE if the
4369 IP/DNS could not be resolved. Though, it returns the IP address
4370 now even if it could not resolve it (but returns also FALSE).
4371 Affected file lib/silcutil/silcnet.[ch].
4373 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4375 * Added silc_pkcs_decode_identifier to decode the public key's
4376 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4377 Added also silc_pkcs_free_identifier. Added also new context
4378 SilcPublicKeyIdentifier.
4380 * Added -S option to the silc client. It is used to dump the
4381 contents of the specified public key file.
4383 * Changed the PKCS api to return the public key length when
4384 setting the public key.
4386 * Fixed a fatal bug in the public and private key file loading.
4387 Affected file lib/silccrypt/silcpkcs.c.
4389 * Execute the packet parsing for client with zero (0) timeout
4390 if the protocol is active. Affected file silcd/server.c.
4392 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Made the key generation options to the silcd program. Added
4395 -C option, equivalent to client's option.
4397 * Added new [ServerKeys] config section to the server. It
4398 configures the server's public and private key.
4400 * Defined generic Public Key Payload into the protocol
4401 specification to send specific type of public keys and
4404 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4405 public key or certificate.
4407 * Implemented the GETKEY command to the server and to the
4408 client library and on user interface.
4410 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Made preliminary `make install' work.
4414 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added SilcServerRekey context into silcd/idlist.h.
4418 * Added the PFS support as defined in the specification to the
4419 SKE protocol. Affected files lib/silcske/*.c.
4421 * Added `ske_group' field to the SilcServerRekey context to hold
4422 the number of the SKE group that is used with PFS in re-key.
4423 Affected file silcd/idlist.h.
4425 * Added PFS re-key support to the server. Affected file is
4428 * Added silc_protocol_cancel to cancel execution of the next
4429 state of the protocol. Affected file is
4430 lib/silccore/silcprotocol.[ch].
4432 * Added the re-key support with and without PFS to the client
4433 library. Re-key is performed once in an hour, by default.
4435 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4436 Added silc_client_rekey_callback and silc_client_rekey_final.
4437 Affected files are lib/silcclient/protocol.[ch] and
4438 lib/silcclient/client.[ch].
4440 * Removed the `hmac_key' and `hmac_key_len' fields from the
4441 SilcClientConnection structure; not needed. Affected file is
4442 lib/silcclient/client.h.
4446 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Do not ask whether user wants to use the negotiated private key
4449 for private messages, just use it. Affected file is
4450 silc/local_command.c.
4452 * Added `send_enc_key' and `enc_key_len' fields to the
4453 SilcIDListData structure since they are needed in the re-key
4454 phase. Affected file is silcd/idlist.[ch].
4456 * Implemented the simple re-key protocol into the server.
4457 Affected files silcd/server.c and silcd/protocol.[ch]. The
4458 re-key will be performed once in an hour, by default.
4460 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4461 Added silc_server_rekey, silc_server_rekey_callback and
4462 silc_server_rekey_final.
4464 * Removed Tunneled flag from the protocol. Updated the code
4465 and the specifications.
4467 * Adde `pfs' field to the SilcIDListData to indicate whether
4468 the PFS is to be performed in the re-key. Affected file is
4471 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4474 int64 of at least the xintXX size. If void * is less that 4
4475 bytes uint32 * will be used. Defined bool as boolean.
4477 * Changed _ALL_ unsigned long and unsigned int to uint32,
4478 unsgined short to uint16 in the source tree.
4480 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4481 not handle clients that has entry->data.registered == FALSE.
4482 They are not in the network anymore. Affected file is
4485 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Implemented the sending of the SERVER_SIGNOFF notify in the
4488 server. Affected file is silcd/server.c.
4490 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4491 Added also silc_notify_payload_encode_args into the
4492 lib/silccore/silcnotify.[ch].
4494 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4495 Affected file silcd/packet_receive.c.
4497 * Implemented the SERVER_SIGNOFF notify handling in the client
4498 library. Affected file lib/silcclient/client_notify.c. Also,
4499 implemnted the printing of the SERVER_SIGNOFF info to the
4500 application. Affected file silc/client_ops.c.
4502 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4503 if the deleting was successful. Affected file silcd/idlist.[ch].
4505 * Added support for public key authentication in the connection
4506 authentication protocol in the client library. Affected file
4507 lib/silcclient/protocol.c.
4509 * Changed the server's silc_idlist_get_clients_by_* interface
4510 to support already allocated array so that new entries may be
4511 added to pre-allocated array. Affected file silcd/idlist.[ch].
4512 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4513 and command replies.
4515 * All command reply functions in the server now calls the
4516 pending command callback even if error occured. This way the
4517 error will be delivered to the client as well. Affected files
4518 silcd/command.c and silcd/command_reply.c.
4520 * Fixed INFO command to return local server's info if no server
4521 was provided. Affected file lib/silcclient/command.c.
4523 * Removed RESTART command for good. Updated the code and the
4526 * Rewrote parts of the task system. It is a bit simpler now.
4527 Removed unsued task priorities. The affected files are
4528 lib/silcutil/silctask.[ch].
4530 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Moved the USERS printing from the library to the application.
4533 Affected files lib/silcclient/command.c and silc/client_ops.c.
4535 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Added channel key re-key support. The re-key is perfomed
4540 only by the router and is done once in an hour. Added `rekey'
4541 field to the SilcChannelEntry in the server. Affected files
4542 silcd/server.c and silcd/idlist.h.
4544 * Added silc_task_unregister_by_context into the file
4545 lib/silcutil/silctask.[ch].
4547 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Added SILC_UMODE_GONE mode to indicate when the client is not
4550 present in the SILC network. Added also support to the local
4551 command AWAY that will set this mode. Added support of showing
4552 "xxx is gone" in WHOIS command. The USERS command shows the
4553 gone status as well.
4555 * Fixed setting server and router operator privileges in the
4556 server's UMODE command. Affected file silcd/command.c.
4558 * Merged the SKE KE1 and KE2 payloads into one payload. The
4559 new KE payload is equivalent to the old KE2 payload.
4561 Cleaned up the SKE Start Payload parsing. It now uses the
4562 simple buffer unformatting to do the parsing. A lot faster
4565 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4566 to the SKE that is used to indicate whether both of the SKE
4567 parties should perform authentication. By default only the
4568 responder performs authentication. By setting this flag also
4569 the initiator must do authentication. By default it is unset
4570 since in normal SKE case, client to server connection, only
4571 the responder should do authentication. When doing SKE between
4572 two clients both should perform authentication. Updated the
4573 code and the protocol specs.
4575 * A little fix to IDENTIFY command in the server. Search the
4576 client first by hash not nickname. Affected file is
4579 * Fixed the silc_client_close_connection to support closing
4580 the client to client connections wihtout deleting too much
4581 data. Affected file lib/silcclient/client.c.
4583 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4584 are received if protocol used to be active but is not anymore
4585 the application would crash due to NULL pointer dereference.
4586 Affected files silcd/server.c and lib/silcclient/client.c.
4588 * Added `hash' field to the SilcClientConnection to include
4589 the hash function negotiated in the SKE protocol.
4591 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4592 to set the channel founder authentication data. A client can
4593 claim the founder rights later by providing the authentication
4594 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4595 This way the channel founder can regain the channel founder
4596 privileges even it is left the channel. This works only on
4597 local server and the client must be connected to the same
4598 server to be able to regain the founder rights. Updated the
4599 protocol specs accordingly.
4601 Added support to the CMODE command in the client to set the
4602 founder auth data. Read the README to see how to set it.
4604 Added support to the CUMODE command to claim the founder
4605 rights. Read the README to see how to do it.
4607 Added support for the founder authentication to the Channel
4608 Entry in the server. Affected file silcd/idlist.h.
4610 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4611 server's CMODE command. Affected file silcd/command.c.
4613 * Added the following new functions into lib/silccore/silcauth.[ch]:
4614 silc_auth_get_method and silc_auth_get_data.
4616 * The server now saves the remote hosts public key to the
4617 SilcIDListData pointer. Affected file silcd/protocol.c.
4619 * The normal server now does not remove the channel entry from
4620 the cache if the founder authentication data is set. It used
4621 to remove it if the founder was the last one on the channel on
4622 the server and left the channel. The auth data is saved and
4623 if the channel is re-joined later the old entry is used with
4624 the old auth data. Affected files silcd/command_reply.c and
4627 * Removed the `pkcs' field from the SilcIDListData structure
4628 in the server; it is not used. Affected file silcd/idlist.h.
4630 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Fixed packet processing on slow links. Partial packets were
4633 never re-processed because the incoming data buffer was cleared
4634 by the application. Application must not directly clear the
4635 sock->inbuf, the packet processing routines handle it. Fixed
4636 this in client library and in server.
4638 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Fixed the WHOIS and IDENTIFY send reply function to really
4641 check whether to send list or just one entry. Affected file
4644 * Cleaned up the LEAVE command's channel key distribution. The
4645 affected file silcd/command.c.
4647 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4648 can enforce the channel mode as well. In that case the ID
4649 includes the ID of the server. The code now enforces the
4650 mode change if the router have different mode than the server.
4652 * The notify client operation with CMODE_CHANGE notify can now
4653 return NULL client_entry pointer if the CMODE was not changed
4654 by client. Application must check for this.
4656 * Added <Server ID> argument to INFO command to support server
4657 info fetching by Server ID.
4659 * Added silc_server_announce_get_channel_users to get assembled
4660 packets of channel users of the specified channel. Affected
4661 file silcd/server.[ch].
4663 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4664 was freed underneath the ID Cache.
4666 * Re-announce clients when the server received CHANNEL_CHANGE
4667 notify from the router. Affected file silcd/packet_send.c.
4669 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4672 crashed since it did not handle the fact that there is no cipher
4673 called "3" and didn't check the error condition. Now fixed.
4675 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4676 flag. It can be used to send message requests.
4678 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Implemented the RESTART command in the client.
4682 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4683 notice type messages. Added notice printing to the user
4686 * The channel keys are not re-generated if the channel's mode
4687 is PRIVKEY, ie private key on the channel exists. Affected
4688 files silcd/server.c and silcd/command.c.
4690 * Fixed a little bug in channel message delivery when channel
4691 private keys are set in the server. Affected file is
4692 silcd/packet_send.c.
4694 * Changed the setting on channel->on_channel = TRUE from the
4695 silc_client_save_channel_key to the JOIN command reply. The
4696 key payload is not received if the private channel key is set.
4697 Affected file lib/silcclient/command_reply.c and the
4698 lib/silcclient/client_channel.c.
4700 * When the CMODE_CHANGE notify is sent and the channel private
4701 key mode is removed the channel key must be re-generated in
4702 other cells as well. Added this support for the router in the
4703 silcd/packet_receive.c.
4705 * Added new local command NOTICE to send notice message on
4706 channel. Affected file silc/local_command.[ch].
4708 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Added new local command ME to the client. It is used to send
4711 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4712 some action. Affected file silc/local_command.[ch].
4714 * Changed channel_message and private_message client operations
4715 to deliver the message flags to the application. Added also
4716 the `flags' arguments to the silc_client_send_channel_message
4717 and silc_client_send_private_message functions. Affected file
4720 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Redefined the Private Message Payload to support private message
4723 keys and to support the new private message flags. Updated
4724 the protocol specs. Flags makes it possible to have for example
4725 CTCP style messages.
4727 * Added new type SilcPrivateMessagePayload and defined an API
4728 for it in the lib/silcclient/silcprivate.[ch].
4730 * Tested private message private keys successfully. Tested the
4731 private message key set, unset and list commands with the new
4734 * Redefined the Channel Message Payload to include the channel
4735 message flags (equal with private message flags) to support
4736 for example CTCP style messages.
4738 * Defined some of the message (for channel and private message)
4739 flags. Updated the protocol specs and added the flags to the
4740 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4742 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added SilcKeyAgreementStatus type to the key agreement routines
4745 to indicate the current status and error if one occured.
4746 The status types are defined in the lib/silcclient/silcapi.h.
4748 * Added new local command KEY that is used to set and unset private
4749 keys for channels, set and unset private keys for private messages
4750 with remote clients and to send key agreement requests and
4751 negotiate the key agreement protocol with remote client. The
4752 key agreement is supported only to negotiate private message keys,
4753 it currently cannot be used to negotiate private keys for channels,
4754 as it is not convenient for that purpose.
4756 * Fixed a minor pending callback setting bug in the function
4757 silc_client_get_client_by_id_resolve, now the function works.
4758 Affected file lib/silcclient/idlist.c.
4760 * Added function silc_net_get_local_port to get local bound
4761 port by socket. Added to lib/silcutil/silcnet.[ch].
4763 * Added `sockets' and `sockets_count' fields to the SilcClient
4764 object. They hold the sockets of the listenning sockets in
4765 the client. Listenning sockets may be for example the key
4766 agreement server. Affected file lib/silcclient/client.[ch].
4767 Added functions the silc_client_add_socket and the
4768 silc_client_del_socket. They are exported to the application
4771 * Added ~./silc/clientkeys to support other client's public keys.
4773 * Renamed verify_server_key client operation to verify_public_key
4774 and added one argument to indicate the type of the connection
4775 (server, client etc.).
4777 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added silc_server_connection_auth_request to handle the
4780 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4781 silcd/packet_receive.[ch].
4783 * Added silc_server_send_connection_auth_request into the
4784 silcd/packet_send.c to send the connection auth request packet.
4786 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4789 * Fixed the public key authentication in responder side in the
4790 server. The `auth_data' pointer includes the SilcPublicKey
4791 not the path to the public key. Affected file silcd/protocol.c.
4793 * Implemented the public key authentication in the initiator side
4794 in the server. Affected file silcd/protocol.c.
4796 * Removed the [RedirectClient] config section from the server
4797 configuration. Is not needed and I don't want to implement it.
4799 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * Cleaned up the CMODE command in the server. It now works
4802 correctly and supports all the modes defined in the protocol.
4803 Affected file is silcd/command.c.
4805 * Added `hmac_name' field to the SilcChannelEntry in the server
4806 to hold the default HMAC of the channel. It can be set when
4807 creating the channel (with JOIN command). Affected files
4810 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4811 type to indicate the change of the current cipher and hmac
4812 on the channel. Client can safely ignore the <cipher> argument
4813 (if it chooses to do so) since the CHANNEL_KEY packet will
4814 force the channel key change anyway. The <hmac> argument is
4815 important since the client is responsible of setting the new
4816 HMAC and the hmac key into use.
4818 * Fixed the CMODE command in the client library as well.
4820 * Tested CMODE command in router environment successfully.
4822 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4824 * Show the version of the remote client (or server) when connecting
4825 to the server. It is logged to the log file. Affected file
4826 is silcd/protocol.c.
4828 * Fixed the KILLED notify handling in the client library. The
4829 client must be removed from all channels when receiving the
4832 Also, do not remove the client entry when giving the KILL
4833 command but when the KILLED notify is received.
4835 * Removed silc_idlist_find_client_by_nickname from the server.
4836 Not needed anymore. Affected files silcd/idlist.[ch].
4838 * Implemented the CHANNEL_CHANGE notify type handling to the
4839 server. Affected file silcd/server.c.
4843 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Added silc_server_send_notify_invite to send the INVITE
4846 notify between routers.
4848 * Implemented the INVITE command correctly to the server.
4850 * Implemented the INVITE notify type handling in the server.
4852 * Implemented the INVITE command to the client library and on the
4855 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Added function silc_server_get_client_resolve to find the
4858 client entry by ID from all ID lists and then resolve it
4859 (using WHOIS) if it cannot be found. Affected file is
4862 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Implemented the BAN command to the client library.
4866 * The JOIN command in the server now checks the invite list
4869 * Changed the silc_command_reply_payload_encode_va and the
4870 silc_command_payload_encode_va to support that if argument is
4871 NULL it ignores and checks the next argument. Affected file
4872 lib/silccore/silccommand.c.
4874 * Added silc_server_send_notify_ban to send the BAN notify
4875 type between routers.
4877 * Chaned the silc_notify_payload_encode to support that if
4878 argument is NULL it ignores and checks the next argument.
4879 Affected file lib/silccore/silcnotify.c.
4881 * Tested ban lists in router environment successfully.
4883 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Implemented BAN command to the server, in silcd/command.[ch].
4887 * Removed the BAN and INVITE_LIST modes from the CMODE command
4890 * Added function silc_string_match to regex match two strings.
4891 Affected files lib/silcutil/silcutil.[ch].
4893 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Redefined parts of the SilcChannelEntry in the server to support
4896 the new ban and invite lists.
4898 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Redefined the INVITE command. The same command can be used to
4901 invite individuals to the channel but also to manage the invite
4902 list of the channel (to add to and remove from the invite list).
4903 Updated the protocol specs.
4905 * Added new command SILC_COMMAND_BAN that can be used to manage
4906 the ban list of the channel. Updated the protocol specs.
4908 * Removed the channel modes: the SILC_CMODE_BAN and the
4909 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4910 in the CMODE command. The equivalent features are now available
4911 using INVITE and BAN commands. Updated the protocol specs.
4913 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4914 in the network about change in the current ban list. The notify
4915 type is not used by the client.
4917 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4918 support the invite lists.
4920 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Added new function silc_string_regexify that converts string
4923 including wildcard characters into regex string that can
4924 be used by the GNU regex library. Added into the file
4925 lib/silcutil/silcutil.[ch].
4927 Added silc_string_regex_combine to combine to regex strings
4928 into one so that they can be used as one regex string by
4929 the GNU regex library. Added into the file
4930 lib/silcutil/silcutil.[ch].
4932 Added silc_string_regex_match to match two strings. It returns
4933 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4935 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Imported GNU regex to the soruce tree into lib/contrib.
4938 Fixed some compiler warning from the regex.c.
4940 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Fixed MOTD command in the server to work in router environment.
4944 * Fixed the MOTD command in the client library to support
4945 the server argument in the command.
4947 * Added `nickname_len' argument to the silc_idlist_add_client
4948 in the server, as the `nickname' argument may be binary data
4951 * Added silc_idlist_get_channels to return all channels from
4954 * Implemented LIST command to the server. Affected file is
4957 * Implemented the LIST command to the client library and on the
4960 * Added [<user count>] argument to the LIST command reply.
4961 With private channels the user count is not shown.
4963 * Updated TODO and README.
4965 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * The client entry's data.registered must be TRUE even with
4968 global client entry on global client list. The data.registered
4969 is used to check whether the client is anymore in the network,
4970 for example with WHOWAS command so it must be valid.
4972 * Fixed the WHOWAS command in the server. It now actually works
4973 in router environment. Added function into silcd/command_reply.c
4974 silc_server_command_reply_whowas_save.
4976 * Added silc_idlist_purge function to the silcd/idlist.c
4977 to periodically purge the ID Cache.
4979 * Fixed INFO command in the server. It works now in router
4980 environment. Added <server name> argument to the INFO command
4981 reply. Updated the protocol specs.
4983 * Fixed minor bug in silc_idcache_purge to not purge if the
4984 expire value is zero.
4986 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4987 they were buggy because of the WHOWAS information.
4989 * Fixed local command MSG to handle the async resolving of
4990 the remote client properly. It used to fail the first MSG.
4991 Affected file silc/local_command.c.
4993 * Added `data_len' field to SilcIDCache context.
4995 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Update TODO. Todo in commands in the server.
4999 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5002 used by routers as broadcast packet to inform other routers
5003 about the changed user mode.
5005 Implemented the notify handling in the server. Affected file is
5006 silcd/packet_receive.c. Added the function
5007 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5009 * Added new generic Channel Payload and deprecated the New Channel
5010 Payload. The New Channel Payload is now the generic Channel
5013 * Added new argument `mode' to the silc_server_send_new_channel
5014 as it is required in the Channel Payload now.
5016 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5017 and created a new and real SilChannelPayload to represent the
5018 new generic Channel Payload. Implemented the encode/decode
5019 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5021 * Added silc_server_get_client_channel_list to return the list
5022 of channels the client has joined for WHOIS command reply.
5023 Affected file silcd/server.[ch].
5025 * Implemented the channel list sending in the WHOIS command reply
5026 in server and in the client.
5028 Implemented the channel list displaying on the user interface
5029 as well. Affected file silc/client_ops.c.
5031 * Added silc_channel_payload_parse_list to parse list of Channel
5032 Payloads. It returns SilcDList list of SilcChannelPayloads.
5033 Client for example can use this function to parse the list of
5034 channels it receives in the WHOIS command reply. The caller
5035 must free the list by calling silc_channel_payload_list_free.
5036 Affected files lib/silccore/silcchannel.[ch].
5038 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Added one new argument <user mode> to the WHOIS command reply
5041 to return the mode of the user in SILC. Updated the protocol
5044 Implemented it to the server and client.
5046 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Fixed the mode printing on the user interface on joining.
5049 Affected file silc/client_ops.c.
5051 * Implemented the UMODE command and user modes in general to the
5052 client library and to the user interface.
5054 * Implemented the UMODE command to the server.
5056 * The server now sends UNKNOWN_COMMAND error status if client sends
5057 unknown command. Affected file silcd/command.c.
5059 * All server commands now handle the command identifier the right
5060 way when sending the command reply to the client. The client can
5061 use to identify the command replies with the identifier.
5063 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Added silc_server_get_client_route to resolve the route to
5066 the client indicated by the client ID. Affected file is
5069 * Added silc_server_relay_packet as general function to relay
5070 packet to arbitrary destination. This deprecates functions
5071 like _send_private_message_key, _relay_notify etc. Affected
5072 file is silcd/packet_send.[ch].
5074 Removed silc_server_send_key_agreement,
5075 silc_server_send_private_message_key and
5076 silc_server_packet_relay_notify functions from the file
5077 silcd/packet_send.[ch].
5081 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5082 server. Affected file silcd/packet_receive.[ch].
5084 * Implemented the KILL command to the client. Implemented the
5085 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5086 Affected files lib/silcclient/command[_reply].c and
5087 lib/silcclient/client_notify.c. Implemented the KILL notify
5088 printing in the user inteface.
5090 * Fixed a lot silc_parse_nick memory leaks from the client
5091 library in the file lib/silcclient/command.c.
5093 * Changed the silc_server_send_notify_on_channels's `sender'
5094 argument from SilcSocketConnection to SilcClientEntry to
5095 check the sender as entry and not as connection object and not
5096 to send to the client provided as argument. The affected file
5097 is silcd/packet_send.[ch].
5099 * The notify packets that are destined directly to the client used
5100 to not to be processed by the server. Now changed that and the
5101 server processes all notify packets. After relaying the packet
5102 to the client the notify packet is processed in the server.
5104 * The silc_server_free_client_data now checks whether there is
5105 pending outgoing traffic for the client and purges the data to
5106 the network before removing the client entry.
5108 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5111 an client is killed from the SILC Network. Updated the protocol
5114 Added new function silc_server_send_notify_killed to the
5115 silcd/packet_send.[ch].
5117 * Added function silc_server_packet_relay_notify to relay notify
5118 packets that are destined directly to a client. In this case
5119 the server does not process the notify packets but merely relays
5120 it to the client. Affected file silcd/packet_send.[ch].
5122 Added also silc_server_packet_process_relay_notify to check
5123 whereto relay the notify. Affected file is
5124 silcd/packet_receive.[ch].
5126 * Implemented the KILL command to the server.
5130 * Added the backup schema desgined last fall to the protocol
5131 specs for everyone to see. The specification is in the
5132 *-spec-xx.txt draft and the packet type definitions for the
5133 backup routers is in *-pp-xx.txt draft. Thusly, added also
5134 new packet type SILC_PACKET_CELL_ROUTERS.
5136 * A big security problem in the implementation discovered. The
5137 signoff of an client did not cause new channel key generation
5138 which it of course should've done. The channel keys must be
5139 always re-generated when client leaves (or signoffs) the channel.
5140 The silc_server_remove_from_channels funtion now handles
5141 the channel key re-generation.
5143 * Added `sender' argument to the silc_server_send_notify_on_channels
5144 to not to send the client provided as argument. Affected file
5145 silcd/packet_send.[ch].
5147 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Implemented OPER and SILCOPER commands into the server and
5152 * Added silc_auth_verify and silc_auth_verify_data to verify
5153 the authentication directly from the authentication payload.
5154 It supports verifying both passphrase and public key based
5155 authentication. Affected file lib/silccore/silcauth.[ch].
5157 * Added `hash' field to the SilcIDListData structure. It is the
5158 hash negotiated in the SKE protocol. Affected file is
5161 * Slight redesigning of the SilcAuthPayload handling routines.
5162 Do not send SilcPKCS but SilcPublicKey as argument.
5164 * Implemented the public key authentication support to the
5165 serverconfig. The public key is loaded from the provided path
5166 and saved as authentication data to void * pointer. Thus,
5167 changed the unsigned char *auth_data to void *auth_data;
5169 * Fixed SHUTDOWN command to send the reply before the server
5170 is shutdown. :) Affected file silcd/command.c.
5172 * Fixed fatal bug in CONNECT command. The hostname was invalid
5173 memory and server crashed. Affected file silcd/command.c.
5175 * Fixed fatal bug in CLOSE command. The server_entry became
5176 invalid but was referenced later in the command. Affected file
5179 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Fixed fatal bug in failure packet handling. Server ignored
5182 the failure and thus crashed when it came.
5186 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5189 that the command may be executed only once in (about) 2 seconds.
5190 The old SILC_CF_LAG flag is same but allows command bursts up
5191 to five before limiting.
5193 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5194 server code. Various commands now includes the CF_LAG_STRICT
5195 flag to disallow any kind of miss-use of the command.
5197 * Fixed the silc_buffer_unformat to not to allocate any data
5198 if the length of the data is zero. It used to allocate the
5199 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5201 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Changed the format of AdminConnection configuration section
5204 in the server. Added username of the admin to the format.
5205 Affected files silcd/serverconfig.[ch].
5207 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5208 to return admin configuration data by host, username and/or
5211 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Implemented WHOWAS command to the server. Added the functions:
5215 silc_server_command_whowas_parse,
5216 silc_server_command_whowas_send_reply,
5217 silc_server_command_whowas_from_client and
5218 silc_server_command_whowas_from_server
5220 * Added <Client ID> argument to the WHOWAS command reply. Updated
5221 the protocol specs accordingly.
5223 * Implemented WHOWAS command and command_reply to the client
5226 Implemented the WHOWAS printing on the user interface.
5228 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Added new argument to the WHOWAS command reply, the real name.
5231 It is an optional argument. Updated the protocol specs.
5233 * Added SilcIDCacheDestructor callback that is registered when
5234 the SilcIDCache is allocated. The callback is called when
5235 an cache entry in the ID Cache expires, or is purged from the
5236 cache. Added into lib/silccore/idcache.[ch].
5238 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5239 to destruct the client entries when the cache entry expires.
5240 Other ID Cache's in server and in the client library ignores
5243 * If the ID Cache entry's `expire' field is zero then the entry
5244 never expires. Added boolean `expire' argument to the
5245 silc_idcache_add function in the lib/silccore/idcache.[ch].
5246 If it is TRUE the default expiry value is used.
5248 * Added silc_server_free_client_data_timeout that is registered
5249 when client disconnects. By default for 5 minutes we preserve
5250 the client entry for history - for WHOWAS command.
5252 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Added support to the server to enforce that commands are not
5255 executed more than once in 2 seconds. If server receives
5256 commands from client more frequently, timeout is registered
5257 to process the commands. Affected file silcd/command.c.
5258 Added new function silc_server_command_process_timeout.
5260 * Changed NICK_NOTIFY handling in client library to check that
5261 if the client's nickname was changed, so there is no need to
5262 resolve anything from the server.
5264 * Removed error printing from the WHOIS and IDENTIFY commands.
5265 If error occurs then it is ignored silently in the client library.
5266 The application, however, may map the received error to
5267 human readable error string. The application currently maps
5268 the NO_SUCH_NICKNAME error to string.
5270 * Made the command status message public to the application. Moved
5271 them from lib/silcclient/command_reply.c to
5272 lib/silcclient/command_reply.h. The application can map the
5273 received command status to the string with the
5274 silc_client_command_status_message function.
5276 * Added check to the server to check that client's ID is same
5277 as the Source ID in the packet the client sent. They must
5280 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Added dist-bzip hook to the Makefile.am to make bzip2
5283 compressed distributions.
5285 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5287 * Server now enforces the maximum length for the nickname and
5288 the channel as protocol specification dictates. 128 bytes for
5289 nickname and 256 bytes for channel name.
5291 * Moved the WHOIS printing to the application. The client libary
5292 does not print out the WHOIS information anymore, the application
5293 must do it. Renamed silc_client_command_reply_whois_print to
5294 the silc_client_command_reply_whois_save.
5296 The client's idle time is also sent to the application now, and
5297 the idle is shown on screen.
5299 * Added silc_client_command_reply_identify_save to save the
5300 received IDENTIFY entries.
5302 * Do not check for channel private keys in message sending and
5303 reception if the channel does not have the PRIVKEY mode set.
5304 Affected file lib/silclient/client_channel.c.
5306 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5309 just surfaced after chaning the JOIN procedure.
5311 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Added silc_client_get_clients_by_list to get client entries
5314 from Client ID list, that is returned for example by JOIN
5315 and USERS command replies. The application should use this
5316 function for example when JOIN command reply is received to
5317 resolve the clients already on the channel (library does not
5318 do that anymore as USERS command reply is not used in the JOIN
5319 procedure anymore). Affected files lib/silcclient/silcapi.h and
5320 lib/silcclient/idlist.c.
5322 * JOIN command reply and USERS command reply returns now SilcBuffer
5323 pointers instead of unsigned char pointers when returning
5324 the client list and mode list.
5326 * Added <Client ID> argument to the JOIN command reply, mainly
5327 for the server to identify for which client the command was
5328 originally sent. Updated protocol specs accordingly.
5330 * Added SilcDlist private_key pointer to the SilcChannelEntry
5331 in the client to support the channel private keys. Affected
5332 file is lib/silcclient/idlist.h.
5334 * Added SilcChannelPrivateKey argument to the function
5335 silc_client_send_channel_message so that application can choose
5336 to use specific private ke if it wants to. If it is not provided,
5337 the normal channel key is used, unless private keys are set.
5338 In this case the first (key that was added first) is used
5339 as the encryption key.
5341 * Implemented the support for channel private key handling.
5342 Implemented the following functions:
5344 silc_client_add_channel_private_key,
5345 silc_client_del_channel_private_keys,
5346 silc_client_del_channel_private_key,
5347 silc_client_list_channel_private_keys and
5348 silc_client_free_channel_private_keys
5350 Affected file lib/silcclient/client_channel.c.
5352 * Added the support for the private keys in the channel message
5353 sending and encryption and in the message reception and
5354 decryption. Affected funtions are
5355 silc_client_send_channel_message and silc_client_channel_message.
5357 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5359 * Added SKE's key verify callback to the client library's
5360 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5362 * Removed the statement that server (or router) must send USERS
5363 command reply when joining to the channel so that the client
5364 knows who are on the channel. Instead, the client list and
5365 client's mode list is now sent in the JOIN command reply to the
5366 client who joined channel. This is better solution.
5368 * Added function silc_server_get_users_on_channel and function
5369 silc_server_save_users_on_channel to the silcd/server.[ch].
5371 * Removed function silc_server_command_send_users from the
5374 * Do not show topic on the client library anymore. The topic is
5375 sent in the command reply notify to the application and the
5376 application must show the topic now.
5378 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added client searching by nickname hash into the IDENTIFY and
5381 WHOIS commands in the server as they were clearly missing from
5382 them. Affected file is silcd/command.c.
5384 * Fixed a bug in private message receiving in the client library.
5385 The remote ID was freed and it wasn't supposed, now it is
5388 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Minor fix to the channel payload; allocate the data area, as it
5391 needs to be of specific length.
5393 * If the key agreement port is zero then the operating
5394 system will define the bound port. Affected files are
5395 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5397 * Added new function silc_channel_payload_decrypt into the file
5398 lib/silccore/silcchannel.[ch].
5400 * Moved the channel message etc, check from silc_packet_decrypt
5401 to applications. The library calls now a generic
5402 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5403 when the packet is either normal or special. This was done to
5404 allow more wide range of checking that was not allowed when
5405 the code was in library. Now applications can do virtually any
5406 checks to the packet and return to the library the decision how
5407 the packet should be processed. Affected files are
5408 lib/silccore/silcpacket.[ch].
5410 Added silc_server_packet_decrypt_check to the server and
5411 silc_client_packet_decrypt_check to the client library.
5413 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5414 to send with specified source and destination information.
5416 * Channel message delivery between routers was broken after the
5417 channel key distribution was fixed earlier. The channel key
5418 was used be to distributed to other routers as well which is not
5419 allowed by the protocol. Now this is fixed and channel keys
5420 really are cell specific and the channel message delivery between
5421 routers comply with the protocol specification.
5423 * Fixed various commands in server to check also the global list
5424 for the channel entry and not just the local list. The affected
5425 file silcd/command.c.
5427 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added assert()s to buffer formatting and unformatting routines
5430 to assert (if --enable-debug) when error occurs. Affected
5431 file: lib/silcutil/silcbuffmt.c.
5433 * Changed to auto-reconnect to check whether the remote host is
5434 router and register the re-connect timeout if it is. It used
5435 to check that whether we are normal server, but router must do
5436 auto-reconnect with another router as well. Affected file
5439 * Removed the [<key len>] option from CMODE command as the cipher
5440 name decides the key length, nowadays. See the defined ciphers
5441 from the protocol specification.
5443 * Added [<hmac>] option to the CMODE command to define the HMAC
5444 for the channel. Added SILC_CMODE_HMAC channel mode.
5446 * Added [<hmac>] option for the JOIN command so that user can
5447 select which HMAC is used to compute the MACs of the channel
5450 * Added Hmac field to the Channel Message Payload. The integrity
5451 of plaintext channel messages are now protected by computing
5452 MAC of the message and attaching the MAC to the payload. The
5453 MAC is encrypted. Now, it is clear that this causes some
5454 overhead to the size of the packet but rationale for this is that
5455 now the receiver can verify whether the channel message decrypted
5456 correctly and also when private keys are set for the channel the
5457 receiver can decrypt the packet with several keys and check from
5458 the MAC which key decrypted the message correctly.
5460 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5461 lib/silccrypt/silccipher.[ch].
5463 * Added silc_hash_len to return the digest length into the
5464 lib/silcrypt/silchash.[ch].
5466 * Rewrote parts of Silc Channel Payload interface in the
5467 lib/silccore/silcchannel.[ch]. The encode function now also
5468 encrypts the packet and parse function decrypts it.
5470 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Fixed a minor formatting bug in the SKE's key material processing.
5473 It actually might have processed the keys wrong way resulting
5476 * Redefined the mandatory HMAC algorithms and added new algorithms.
5477 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5478 and hmac-md5 truncated to 96 bits. The mandatory is now
5479 hmac-sha1-96. Rest are optional (including the one that used
5480 to be mandatory). Rationale for this is that the truncated HMAC
5481 length is sufficient from security point of view and can actually
5482 make the attack against the HMAC harder. Also, the truncated
5483 HMAC causes less overhead to the packets. See the RFC2104 for
5486 * Added new [hmac] configuration section. The SKE used to use
5487 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5488 is of course wrong. The official names that must be proposed in
5489 the SKE are the ones defined in the protocol specification
5490 (hmac-sha1-96 for example). The user can configure any hmac
5491 using any hash function configured in the [hash] section. At
5492 least, the mandatory must be configured.
5494 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5496 * Added HMAC list to the SKE proposal list. It has now both
5497 hash algorithm list and HMAC list. This makes the protocol
5498 incompatible with previous versions. The SKE now seems to work
5499 the way it is supposed to work, for the first time actually.
5501 * Defined plain Hash algorithms to the protocol specification.
5504 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Implemented support for key agreement packets into the server.
5507 Added functions silc_server_key_agreement and
5508 silc_server_send_key_agreement. Other than these functions,
5509 server has nothing to do with this packet.
5511 * Added support for private message key packets into the server.
5512 Added functions silc_server_private_message_key and
5513 silc_server_send_private_message_key.
5517 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5518 called in the protocol's final callback instead in the END
5519 protocol state. This makes a little more sense and in the same
5520 time in client we can use the same protocol routines for normal
5521 key exchange and to key agreement packet handling as well.
5523 * Added to both client's and server's KE protocol context the
5524 SilcSKEKeyMaterial pointer to save the key material. We will
5525 bring the key material to the protocol's final callback by doing
5526 this. The final callback must free the key material.
5528 * Added SKE's packet_send callback into client's KE protocol
5529 context so that the caller can choose what packet sending function
5530 is used. This way we can use different packet sending when
5531 doing normal SKE when doing key agreement packet handling (in
5532 the key agreement packet handling we do not want to encrypt
5535 * Implemented the responder side of the key agreement routines
5536 in the client. The client can now bind to specified port and
5537 accept incoming key negotiation. The key material is passed
5538 to the application after the protocol is over.
5540 * Implemented the processing of incoming Key Agreement packet
5541 in the client. Added function silc_client_key_agreement to
5544 * Implemented the intiator side of the key agreement routines
5545 in the client. The client can now initiate key agreement with
5546 another remote client. The key material is passed to the
5547 application after the protocol is over.
5549 * Created client_keyagr.c to include all the key agreement
5552 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5553 SILC_TASK_CALLBACK except that it is not static.
5555 * Created client_notify.c and moved the Notify packet handling
5556 from the client.[ch] into that file.
5558 * Created client_prvmsg.c and moved all private message and
5559 private message key routines from the client.[ch] into that file.
5561 * Create client_channel.c and moved all channel message and
5562 channel private key routines from the client.[ch] into that file.
5564 * Changed silc_client_get_client_by_id_resolve to resolve with
5565 WHOIS command instead of IDENTIFY command, in the file
5566 lib/silclient/idlist.c.
5568 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Implemented the SKE's responder side to the Client library.
5572 * When FAILURE is received to the protocol do not trust it
5573 blindly. Register a timeout to wait whether the remote closes
5574 the connection as it should do it, only after that process the
5575 actual failure. This was changed to both client and server.
5577 * Added client_internal.h to include some of the structures
5578 there instead of client.h in lib/silcclient/.
5580 * Added function silc_task_unregister_by_callback to unregister
5581 timeouts by the callback function.
5583 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Some "Incomplete WHOIS info" errors has been appearing on the
5586 log files. Took away the entry->userinfo check from WHOIS
5587 reply sending. The entry->userinfo is now " " if client did not
5588 provide one. I thought this was fixed earlier but something
5589 is wrong still. Let's see if the error still appears.
5591 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Fixed a minor bug in the login when the channel key is
5594 re-generated in the server. It used to generate the key in
5595 wrong order and thus caused problems in the channel traffic.
5597 * Fixed a minor bug in channel key distsribution after
5598 KICK command. The key was not sent to the router even though
5601 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Added silc_ske_process_key_material_data as generic routine
5604 to process any key material as the SILC protocol dictates. The
5605 function is used by the actual SKE library but can be used by
5606 applications as well. This relates to the private message keys
5607 and the channel private keys since they must be processed the
5608 same way the normal SILC session keys. The protocol dictates
5609 this. Affected files: lib/silcske/silcske.[ch].
5611 Added also silc_ske_free_key_material to free the
5612 SilcSKEKeyMaterial structure.
5614 * Defined silc_cipher_set_key function to set the key for
5615 cipher without using the object's method function. The affected
5616 files: lib/silccrypt/silccipher.[ch].
5618 * Implemented silc silc_client_add_private_message_key,
5619 silc_client_add_private_message_key_ske,
5620 silc_client_del_private_message_key,
5621 silc_client_list_private_message_keys and
5622 silc_client_free_private_message_keys functions in the
5625 Added functions silc_client_send_private_message_key to send
5626 the Private Message Key payload and silc_client_private_message_key
5627 to handle incoming Private Message Key payload.
5629 * Added Cipher field to the Private Message Key payload to set
5630 the cipher to be used. If ignored, the default cipher defined
5631 in the SILC protocol (aes-256-cbc) is used.
5633 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Removed lib/silcclient/ops.h file.
5637 Redefined parts of the SILC Client Library API. Created new
5638 file silcapi.h that deprecates the ops.h file and defines the
5639 published Client Library API. Defined also private message key
5640 API and channel private key API into the file.
5642 This is the file that the application must include from the
5643 SILC Client Library. Other files need not be included by
5644 the application anymore.
5646 * Added new key_agreement client operation callback and also
5647 defined the Key Agreement library API for the application.
5649 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5652 is used by clients to request key negotiation between another
5653 client in the SILC network. If the negotiation is started it
5654 is performed using the SKE protocol. The result of the
5655 negotiation, the secret key material, can be used for example
5656 as private message key.
5658 Implemented the Key Agreement payload into the files
5659 lib/silccore/silauth.[ch].
5661 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Redefined ciphers for the SILC protocol. Added some new ciphers
5664 and defined the key lengths for the algorithms. Changed the
5665 code accordingly. The default key length is now 256 bits.
5667 * Fixed SKE key distribution function silc_ske_process_key_material
5668 when the key length is more than 128 bits. The default key
5669 length in SILC is now 256 bits.
5671 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5672 to indicate unsupported algorithm.
5674 * Renamed rijndael.c to aes.c and all functions as well.
5676 * Fixed a long standing channel key setting bug in client library.
5677 Weird that it has never surfaced before.
5679 * Fixed bug in channel deletion. If the entire channel is removed
5680 then it must also delete the references of the channel entry
5681 from the client's channel list as the client's channel entry and
5682 the channel's client entry share same memory.
5684 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Implemented CONNECT and SHUTDOWN commands in the client.
5688 * Implemented CLOSE command to the client.
5690 * Added the function silc_idlist_find_server_by_name into the
5691 files silcd/idlist.[ch].
5693 Added the function silc_idlist_find_server_by_conn into the
5694 files silcd/idlist.[ch].
5696 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * DIE command was renamed to SHUTDOWN. Updated the both code
5701 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5702 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5704 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5707 * Added function silc_server_create_connection function to create
5708 connection to remote router. My server implementation actually
5709 does not allow router to connect to normal server (it expects
5710 that normal server always initiates the connection to the router)
5711 so the CONNECT command is only good for connecting to another
5714 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5717 or some other client was kicked from the channel.
5719 Implemented the handling of the notify type to both client
5722 Implemented silc_server_send_notify_kicked to send the KICKED
5723 notify. It is used to send it to the server's primary router.
5725 * Implemented the KICK command into server and client.
5727 * Added `query' argument to the silc_idlist_get_client function
5728 to indicate whether to query the client from server or not if
5731 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5732 to indicate that the client is not channel founder.
5736 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Removed the rng context from SilcPacketContext structure and
5739 changed that the packet routine uses the Global RNG API.
5741 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added support for quit message that client can "leave" on the
5744 channel when it quits the SILC. It is ditributed inside the
5745 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5747 Added silc_server_free_client_data that will take the
5748 signoff message as argument.
5750 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5752 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Updated parts of the protocol specification to keep it up
5757 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5760 payloads in one packet.
5762 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5763 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5764 use now the new List flag.
5766 * Also deprecated the following packet types: REPLACE_ID,
5767 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5769 * Added list support for Notify packet in server.
5771 * Added silc_server_send_notify_channel_change to send the
5772 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5773 the silc_server_send_replace_id.
5775 * Added silc_server_send_notify_nick_change to send the
5776 NICK_CHANGE notify type. Deprecates the function
5777 silc_server_send_replace_id.
5779 * Added silc_server_send_notify_join to send the JOIN notify type.
5780 Deprecates the function silc_server_send_new_channel_user.
5782 * Added silc_server_send_notify_leave to send LEAVE notify type.
5783 Deprecates the function silc_server_send_remove_channel_user.
5785 * Added silc_server_send_notify_cmode and
5786 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5787 types. Deprecates the silc_server_send_set_mode function.
5789 * Added SERVER_SIGNOFF notify type to indicate that server has
5790 quit. This means that all clients on the channel from that
5791 server will drop. This can be also used when netsplit happens.
5793 Deprecated REMOVE_ID packet type since it is not needed anymore
5796 Added silc_server_send_notify_server_signoff to send the
5797 SERVER_SIGNOFF notify type. Deprecates the function
5798 silc_server_send_remove_id.
5800 Added also silc_server_send_notify_signoff to send the
5801 SIGNOFF notify type.
5803 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5804 SILC protocol from this day on. Changed the protocol
5805 specification as well.
5807 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5808 notify type. It is used between routers to notify about
5809 topic changes on a channel.
5811 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5814 * Partly updated the protocol specification to comply with the
5815 changes now made. It is still though a bit outdated.
5817 * The JOIN notify type now takes one extra argument <Channel ID>.
5818 The packet used to be destined to the channel but now the
5819 JOIN type may be sent as list thus it is impossible to
5820 destine it to any specific channel. By adding this argument
5821 it is again possible.
5823 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Added CREDITS file. The CHANGES and CREDITS file will appear
5826 in the distribution as well.
5828 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5831 types in the server's silcd/packet_receive.c.
5833 * Implemented CMODE and CUMODE to work in router environment.
5835 * Fixed minor encoding and decoding buglet from the
5836 lib/silccore/silcmode.c.
5838 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5841 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5843 * Changed all SilcConfigServer* and silc_config_server* to
5844 SilcServerConfig* and silc_server_config*, respectively.
5847 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Associated the ID (client or server ID) to the Authentication
5850 Payload to avoid any possibility of forging. Updated the
5851 protocol specification and the code accordingly.
5853 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * The RSA key length is now save to the RsaKey context in the
5856 key generation process in lib/silccrypt/rsa.c. The key length
5857 is now used to figure out the maximum size of the block allowed
5858 to be encrypted/signed.
5860 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5861 is equivalent to the silc_mp_mp2bin but does not allocate any
5864 * Changed silc_mp_mp2bin API to take length argument. If it is
5865 non-zero then the buffer is allocated that large. If zero, then
5866 the size is approximated using silc_mp_sizeinbase, which however
5869 * Created Global RNG API which is global RNG that application can
5870 initialize. After initializing, any routine anywhere in the
5871 code (including library) can use RNG without allocating a new
5872 RNG object. This was done to allow this sort of use of the
5873 RNG in code that has no chance to allocate RNG object. All
5874 applications currently allocate this and many routines in the
5875 library use this. Affected file lib/silccrypt/silcrng.[ch].
5877 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5878 it to use the Global RNG API.
5880 * Defined Authentication Payload into protocol specification that
5881 is used during SILC session to authenticate entities. It is
5882 used for example by client to authenticate itself to the server
5883 to obtain server operator privileges.
5885 Implemented this payload into the lib/silccore/silcauth.[ch].
5886 Implemented also routines for public key based authentication
5887 as the new protocol specification dictates.
5889 Moved definitions of different authentication methods from
5890 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5892 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5893 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5894 silc_pkcs_verify_with_hash functions into the file
5895 lib/silccrypt/silcpkcs.[ch].
5897 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * The client entry's userinfo pointer must be always valid.
5900 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5901 will fail since it requires the userinfo. Now, the userinfo
5902 is allocated as "" if actual userinfo does not exist. Actually,
5903 it must exist and it is totally Ok to drop client connections
5904 that does not announce the userinfo. However, we will make
5905 this workaround for now.
5907 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5908 to return the remote port by socket.
5910 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5913 SILC_SERVER_PENDING_EXEC and added an new macro
5914 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5915 data or when error occurs while processing the pending command.
5917 Added new argument `destructor' into silc_server_command_pending
5918 and to the SilcServerCommandPending object. This destructor is
5919 now called after calling the pending callback or if error occurs
5920 immediately. If error occurs the actual pending callback won't
5921 be called at all - only the destructor. The destructor may be
5922 NULL if destructor is not needed.
5924 All this applies for client library code as well. Similar
5925 changes were made there as well for the pending commands.
5927 In the client, the application must now allocate the
5928 SilcClientCommandContext with the silc_client_command_alloc
5931 * Added reference counter to the SilcServerCommandContext. Added
5932 function silc_server_command_alloc and silc_server_command_dup
5935 Same type of functions added to the client library for the same
5938 * Removed the cmd_ident from IDListData away since it is now
5939 global for all connections. It is the command identifier used
5940 in command sending and with pending commands. The affected file
5943 * Added reference counter to the SilcSocketConnection objecet to
5944 indicate the usage count of the object. The object won't be
5945 freed untill the reference counter hits zero. Currently only
5946 server uses this, and client ignores it. The client must be
5947 set to use this too later. The affected files are
5948 lib/silccore/silcsockconn.[ch]. Added also the function
5949 silc_socket_dup to increase the reference counter.
5951 This was mainly added because it is possible that the socket
5952 is removed underneath of pending command or other async
5953 operation. Now it won't be free'd and proper DISCONNECTING
5954 flags, etc. can be set to avoid sending data to connection that
5955 is not valid anymore.
5957 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5958 the connection. After that it sets SILC_SET_DISCONNECTED.
5959 It is, however, possible that the socket data is not still freed.
5960 The silc_server_packet_process now checks that data is not
5961 read or written to connection that is DISCONNECTED. The socket
5962 get's freed when the reference counter hits zero.
5964 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Changed the client operation API: channel_message operation's
5967 `sender' is now the client entry of the sender, not the nickname
5968 and the `channel' is the channel entry, not the channel name.
5970 In the private_message operation the `sender' is now also the
5971 client entry of the sender not the nickname.
5973 Affected file is lib/silcclient/ops.h and all applications
5974 using the client operations.
5976 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Moved the calling of ops->connect() from connect_to_server_final
5979 into receive_new_id functin since that is the point when the
5980 client is actually allowed to send traffic to network. The
5981 affected file is lib/silcclient/client.c.
5983 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5986 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5987 (if needs broadcasting) instead of broadcasting the packets one
5988 by one which would make a burst in the network traffic.
5990 * Added `broadcast' argument to the functions in silcd/server.[ch]
5991 silc_server_create_new_channel[_with_id] to indicate whether
5992 to send New Channel packet to primary router.
5994 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Added new function into the silcd/server.[ch] files:
5997 silc_server_create_new_channel_with_id to create new channel with
5998 already existing Channel ID.
6000 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6001 lib/silccore/silcpacket.h. This packet is used t send list of
6002 Set Mode payloads inside one packet. Server uses this to set
6003 the modes for the channels and clients on those channels, that it
6004 announced to the router when it connected to it. The protocol
6005 specification has been updated accordingly.
6007 * The silc_server_new_channel did not handle the packet coming
6008 from normal server as it normally does not send that. However,
6009 when it announces its channels it does send it. Implemented
6010 the support for that.
6012 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6013 into the file lib/silccore/id.h.
6015 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Fixed memory leaks in the functions silc_idlist_del_client,
6018 silc_idlist_del_channel and silc_idlist_del_server in the file
6019 silcd/idlist.c. All of those leaked like a sieve.
6021 * Fixed some small memory leaks in the client's function
6022 silc_client_notify_by_server.
6024 * Added functions into silcd/server.c: silc_server_announce_clients,
6025 silc_server_announce_channels and silc_server_announce_server.
6026 These functions are used by normal and router server to announce
6027 to its primary router about clients, channels and servers (when
6028 router) that we own. This is done after we've connected to the
6031 These functions effectively implements the following packet types:
6032 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6033 and SILC_PACKET_NEW_ID_LIST.
6035 * Added new functions into the silcd/packet_receive.[ch]:
6036 silc_server_new_id_list, silc_server_new_channel_list and
6037 silc_server_new_channel_user_list to handle the incoming
6038 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6040 * Added support of changing Channel ID in the function
6041 silc_server_replace_id. If the server that announces a channel
6042 to the router already exists in the router (with same name but
6043 with different Channel ID), router is responsible to send
6044 Replace ID packet to the server and force the server to change
6045 the Channel ID to the one router has.
6047 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6048 client that the Channel ID has been changed by the router. The
6049 normal server sends this to the client. Client must start using
6050 the new Channel ID as the channel's ID.
6052 Implemented handling of this new type into lib/silcclient/client.c
6053 into the function silc_client_notify_by_server.
6055 * Added new function silc_idlist_replace_channel_id into the files
6056 silcd/idlist.[ch] to replace the Channel ID.
6058 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Call silc_server_command_identify_check always when processing
6061 the IDENTIFY command in silcd/command.c
6063 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6066 send keepalive packets. The packet can be sent by clients,
6067 servers and routers.
6069 Added function silc_socket_set_heartbeat into the file
6070 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6071 If not set, the heartbeat is not performed. The actual
6072 heartbeat is implemented in the low level socket connection
6073 library. However, application is responsible of actually
6076 Added silc_server_send_heartbeat to send the actual heartbeat
6077 packet into silcd/packet_send.[ch]. Server now performs
6078 keepalive with all connections.
6080 * Added silc_task_get_first function into lib/silcutil/silctask.c
6081 to return the timeout task with shortest timeout. There was a bug
6082 in task unregistration that caused problems. TODO has been
6083 updated to include that task system must be rewritten.
6085 * The client library will now resolve the client information when
6086 receiving JOIN notify from server for client that we know but
6087 have incomplete information.
6089 * Rewrote parts of silc_server_remove_from_channels and
6090 silc_server_remove_from_one_channel as they did not remove the
6091 channel in some circumstances even though they should've.
6093 * Encryption problem encountered in server:
6095 The LEAVE command used to send the Channel Key packet to the
6096 router immediately after generating it. However, the code
6097 had earlier sent Remove Channel user packet but not immediately,
6098 ie. it was put to queue. The order of packets in the router
6099 was that Channel Key packet was first and Remove Channel User
6100 packet was second, even though they were encrypted in the
6101 reverse order. For this reason, MAC check failed. Now, this
6102 is fixed by not sending the Channel Key packet immediately but
6103 putting it to queue. However, this is more fundamental problem:
6104 packets that are in queue should actually not be encrypted
6105 because packets that are sent immediately gets encrypted
6106 actually with wrong IV (and thus MAC check fails). So, packets
6107 that are in queue should be encrypted when they are sent to
6108 the wire and not when they put to the queue.
6110 However, the problem is that the current system has not been
6111 designed to work that way. Instead, the packet is encrypted
6112 as soon as possible and left to the queue. The queue is then
6113 just purged into wire. There won't be any fixes for this
6114 any time soon. So, the current semantic for packet sending
6117 o If you send packet to remote host and do not force the send
6118 (the packet will be in queue) then all subsequent packets to the
6119 same remote host must also be put to the queue. Only after the
6120 queue has been purged is it safe again to force the packet
6123 o If you send all packets immediately then it safe to send
6124 any of subsequent packets through the queue, however, after
6125 the first packet is put to queue then any subsequent packets
6126 must also be put to the queue.
6128 Follow these rules and everything works fine.
6130 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * Added new function silc_server_remove_clients_by_server to
6133 remove all client entries from ID list when the server connection
6134 is lost. In this case it is also important to invalidate all
6135 client entires as they hold the invalid server entry. This
6136 fixes fatal bug when server has lost connection and will reconnect
6139 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Made some sanity checks to silc_server_daemonise like to check
6142 whether the requested user and group actually exists.
6144 * Added sanity check to SKE's silc_ske_responder_finish to check
6145 that the public and private key actually is valid.
6147 * Invalidate the client's nickname when receiving Replace ID
6148 packet and the Client ID is being replaced. This means that the
6149 server will query the nickname if someone needs it (client)
6152 * Sort the ID Cache in client library when the ID Cache data
6153 has changed (needs sorting).
6155 * Do not allow for SILC client to create several connections to
6156 several servers. The client does not support windows right now
6157 and generating multiple connections causes weird behaviour.
6159 Irssi-silc client does support windows and can handle several
6160 connections without problems, see: www.irssi.org and SILC plugin.
6162 * Fixed some places where client was added to the IDList. The
6163 rule of thumb is following (in order to get everything right):
6164 If the client is directly connected local client then the
6165 `connection' argument must be set and `router' argument must be
6166 NULL to silc_idlist_add_client function. If the client is not
6167 directly connected client then the `router' argument must
6168 bet set and the `connection' argument must be NULL to the
6169 silc_idlist_add_client function.
6171 * The funtion silc_server_packet_send_local_channel actually did
6172 not check whether the client was locally connected or not. It
6173 does that now. Fixed a bug related to LEAVE command.
6175 * Fixed Remove Channel User payload parsing bug in server's
6176 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6178 * The server's silc_server_save_channel_key now checks also the
6179 global ID list for the channel as it might not be in the local
6180 list. Fixed a bug related to LEAVE command.
6182 * Is this the end of the [<unknown>] buglet that has been lurking
6183 around for a long time? A little for loop fix in server's
6184 silc_server_command_whois_parse that is used by both IDENTIFY
6185 and WHOIS command. At least, this was a clear bug and a cause
6186 of one type of [<unknown>] buglet.
6188 * WHOIS and IDENTIFY commands call the function
6189 silc_server_command_[whois/identify]_check function even if
6190 we are not router server.
6192 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Added --with-gmp configuration option. If set the GMP
6195 is always compiled in the SILC source tree. If not set then
6196 it is checked whether the system has the GMP3 installed. If
6197 it has then the GMP won't be compiled (the system's headers
6198 and library is used), if it doesn't have it then the GMP is
6199 compiled in the SILC source tree.
6201 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6203 * Changed RSA private exponent generation to what PKCS #1
6204 suggests. We try to find the smallest possible d by doing
6205 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6206 not security fix but optimization.
6208 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Added new config entry [Identity] to fork the server and run
6211 it as specific user and group. A patch from Bostik.
6213 * Imported Dotconf configuration library into lib/dotconf.
6214 This will be used to create the SILC configuration files later.
6215 It will appear in the distsribution after this commit.
6217 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * A big code auditing weekend happening. Auditing code for
6220 obvious mistakes, bugs and errors. Also, removing any code
6223 Removed files for being obsolete:
6225 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6226 inline in the file lib/silcutil/silcbuffer.h)
6228 o lib/silcutil/silcbufutil.c (the header has inline versions)
6230 Changed code to fix possible error conditions:
6232 o The buffer formatting routines now check that the destination
6233 buffer really has enough space to add the data. This applies for
6234 both buffer formatting and unformatting
6235 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6236 unformatting was changed to accomodate following rules:
6237 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6238 sent to the function while XXX_*STRING will not allocate or copy
6239 the data into the buffer. Instead it sets the pointer from the
6240 buffer into the pointer sent as argument (XXX_*STRING used to
6241 require that the pointer must be allocated already). This change
6242 makes this whole thing a bit more consistent and more optimized
6243 (note that the data returned in the unformatting with XXX_*STRING
6244 must not be freed now). The routines return now -1 on error.
6246 o Tried to find all code that use buffer_format and buffer_unformat
6247 and added return value checking to prevent formatting and
6248 especially unformatting errors and possible subsequent fatal
6251 o Changed ske->x and ske->KEY to mallocated pointers in
6252 lib/silcske/silcske.h. Fixed possible data and memory leak.
6254 o Added return value checking to all *_parse* functions. Fixed
6255 many memory leaks as well.
6257 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6258 so that buffer overflows would not happen. All code now also
6259 checks the return value as it can fail.
6261 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Added reconnection support to server if the normal server looses
6264 its connection to the router (for example if router is rebooted).
6265 The server performs normal reconnection strategy implemented
6266 to the server. Affected file silcd/server.c.
6268 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * Added new packet type SILC_PACKET_SET_MODE that is used to
6271 distribute the information about changed modes (for clients,
6272 channels and clients channel modes) to all routers in the
6273 network. Updated the protocol specification accordingly.
6275 Added functions into silcd/packet_send.c and
6276 silcd/packet_receive.c: silc_server_send_set_mode,
6277 silc_server_set_mode.
6279 Added new files silcmode.[ch] into lib/silccore that implements
6280 the encoding and decoding of Set Mode Payload. Added new type
6281 SilcSetModePayload. Moved the definitions of different modes
6282 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6284 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Oops, a little mistake in server's connection authentication
6287 protocol. The protocol is not ended with FAILURE but with
6288 SUCCESS if the authentication is Ok. :) Affected file is
6291 * Implemented NICK_CHANGE notify handling in server in the file
6292 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6293 the local clients on the channel. After the changing nickname
6294 in router environment snhould work and the [<unknown>] nickname
6295 should appear no more.
6297 The silc_server_replace_id function that receives the Replace ID
6298 payload now sends the NICK_CHANGE notify type also in the file
6299 silcd/packet_receive.c
6301 * Changed WHOIS and IDENTIFY command to support the maximum amount
6302 of arguments defined in protocol specs (3328 arguments). This
6303 fixed a bug that caused problems when there were more than three
6306 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Added extra parameter, command identifier, to the
6309 silc_client_send_command so that explicit command identifier
6312 Changed that ID list routines uses specific command identifier
6313 when sending WHOIS/IDENTIFY requests to the server so that they
6314 can be identified when the reply comes back.
6316 Affected files lib/silcclient/command.[ch],
6317 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6319 * Added `sender' argument to silc_server_packet_send_to_channel
6320 to indicaet the sender who originally sent the packet to us
6321 that we are now re-sending. Ignored if NULL. Affected file
6322 silcd/packet_send.[ch].
6324 * Added some server statistics support in silcd/server_internal.h
6325 SilcServerStatistics structure and around the server code. Also
6326 send some nice statistics information when client is connecting
6329 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Fixed channel ID decoding in server's JOIN command reply in
6332 silcd/command_reply.c
6334 * Fixed braodcasting of replace ID payload to not to send it if
6335 we are standalone server in silcd/packet_receive.c.
6337 * Fixed all channel message sending routines to not to send
6338 packets to clients that has router set, since they are routed
6339 separately in the same function earlier. Affects file
6340 silcd/packet_send.c and all channel packet sending functions.
6342 * In USERS reply, res_argv[i] are not allocated, the table
6343 is allocated. Thus changed that free the table, not its
6346 * In server's whois_check and identify_check if the client is
6347 locally connected do not send any WHOIS commands - they are not
6350 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Fixed some minor bugs in client when sending WHOIS command. The
6353 arguments was in wrong order.
6355 * Removed statis function add_to_channel from server in
6356 silcd/command.c that was previously used with the joining but
6359 * Tested USERS command in router environment successfully with two
6360 routers, two servers and two clients.
6362 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Reorganized the USERS command and command reply in client library
6365 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6366 When the command is given by user we register a pending command
6367 callback that will reprocess the command after the reply has been
6368 received from the server. When reprocessing the packet we then
6369 display the information. Thus, the USERS information is displayed
6370 now in the command callback instead of in the command reply
6371 callback. The processing of the command is same as previously
6372 when server has sent the command reply in the JOINing process.
6374 * Added to USERS command in silcd/command_reply.c to join the client,
6375 we didn't use to know about, to the channel after we've created
6376 a client entry for it. Also, for clienet we did know already still
6377 check whether it is on the channel or not and add it if not.
6379 * Removed silc_server_command_join_notify as the function and its
6382 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Changed the client's pending command handling to the same as the
6385 server's pending command handling. It is also now possible to
6386 execute command reply functions from other command reply
6387 function as the function callbacks for commands and command
6388 replies are one and same. The pending commands are not static
6389 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6390 in client connection context. Thus, pending commands are server
6391 connection specific as it is convenient.
6393 Changed the function silc_client_command_pending and
6394 silc_client_command_pending_del and added new function
6395 silc_client_command_pending_check. Removed the
6396 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6399 * Added cmd_ident, current command identifier, to the client
6400 connection context in lib/silcclient/client.h to keep track on
6401 command identifiers used in command sending. Client's command reply
6402 function handling now supports the mandatory command identifiers.
6404 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6405 funtions in client to fully support pending command callbacks.
6407 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6408 as one of the arguments to the application in the command reply
6411 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6412 before first releasing SILC but came back. Now it is removed again
6413 and should come back nomore. The FORWARDED flag was used only
6414 by the JOINing procedure by forwarding the command packet to router.
6415 Now, the JOINing procedure has been changed to more generic (due
6416 to various router environment issues) and FORWARDED is not needed
6417 anymore for anything. The protocol specification is yet to be
6420 Now, removed silc_server_packet_forward from server and the flag
6421 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6423 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Renamed NAMES command to USERS command. The NAMES was named that
6426 due to historical reasons. Now it is renamed. Also, rewrote
6427 parts of the USERS command. The nickname list is not sent anymore
6428 by the server. Only Client ID and mode lists are sent in the USERS
6429 command. Changed this also to the protocol specification.
6431 The client now resolves the names and stuff after it receives
6432 the USERS list from the server when joining to the channel.
6434 * WHOIS and IDENTIFY commands has been changed to support multiple
6435 Client ID's per command. One can now search for multiple users
6436 in the network by sending only one WHOIS or IDENTIFY command.
6437 Changed the code and the protocol specifications.
6439 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6440 uses silc_server_command_whois_parse to parse the request. */
6442 * If normal server, do not parse the WHOIS and IDENTIFY requests
6443 before sending it to the router. Saves some time.
6445 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Fixed JOIN command on client library. Wrong number of arguments
6448 used to crash the client.
6450 * Added silc_server_channel_has_global function to check whether
6451 channel has global users or not.
6453 * Added silc_server_channel_has_local function to check whether channel
6454 has locally connected clients on the channel.
6456 * The silc_server_remove_from_one_channel now checks whether the
6457 channel has global users or not after given client was removed from
6458 the channel. It also checks whether the channel has local clients
6459 on the channel anymore. If it does not have then the channel entry
6460 is removed as it is not needed anymore.
6462 * The silc_server_notify now checks on JOIN notify whether the joining
6463 client is one of locally connected or global. If it is global then
6464 the channel has now global users on the channel and that is marked
6465 to the channel entry. Also, it now saves the global client to
6466 global list who is joining and JOINs it to the channel. This is
6467 for normal server, that is.
6469 Changed silc_server_send_notify_on_channel,
6470 silc_server_packet_relay_to_channel and
6471 silc_server_packet_send_to_channel check if we are normal server
6472 and client has router set (ie. global client) do not send the
6473 message to that client, as it is already routed to our router.
6475 * Implemented LEAVE notify type handling in silc_server_notify
6478 * Tested LEAVE command in router environment successfully. Tested
6479 with two routers, two servers and two clients.
6483 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6485 * Implemented SIGNOFF notify type handling in silc_server_notify
6488 * silc_server_remove_id now removes the client entry from all channels
6489 it has joined and thusly sends SIGNOFF notify type.
6491 * Rewrote the NAMES list generation in server by removing two excess
6492 loops. The lists are created now inside one loop.
6494 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6496 * silc_server_remove_channel_user checks now also global list
6497 for channel and client.
6499 * silc_server_new_channel_user checks now both local and global
6500 list for channel and client. Fixed a bug in client id decoding.
6501 Used to decode wrong buffer.
6503 * silc_server_channel_message checks now both local and global
6504 list for channel entry.
6506 * Tested channel joining (hence JOIN) in router environment
6507 successfully. Tested with two routers, two servers and two
6510 * Tested channel message sending in router environment successfully.
6512 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Added silc_server_save_channel_key into server.[ch] to save the
6515 received channel key in Channel Key payload processing. It is
6516 also used in JOIN command reply handling.
6518 Equivalent function silc_client_save_channel_key added into
6519 client.[ch] into client library.
6521 * Changed JOIN command reply to send information whether the channel
6522 was created or not (is existing already) and the channel key
6523 payload. Changed protocol specs accordingly.
6525 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6526 the request was sent by ID and not by nickname. Crashed on
6529 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6532 now correctly save the received data.
6534 * silc_server_free_sock_user_data now notifies routers in the
6535 network about entities leaving the network.
6537 At the same time implemented functions silc_server_remove_id
6538 and silc_server_send_remove_id to receive and send REMOVE_ID
6539 packets. The packet is used to notify routers in the network
6540 about leaving entities. The ID removed will become invalid in
6543 * Added function silc_idlist_del_server into server. Removes and
6544 free's server entry from ID list.
6546 * silc_server_private_message function now checks, if we are router,
6547 that the destination ID really is valid ID, naturally.
6549 * In router when NEW_ID packet is received (for new client) the
6550 hash of the Client ID is saved in the ID Cache but the
6551 client->nickname is set to NULL, instead of putting the hash
6554 IDENTIFY command now also checks that client->nickname must be
6555 valid. If it is not if will request the data from the server who
6556 owns the client. Added new function
6557 silc_server_command_identify_check.
6559 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6560 to set the command to already allocated Command Payload.
6562 * Tested private message sending in router environment with two
6563 routers, two servers and two clients. Fixed minor bugs and now
6566 * Fixed segfault from client's NAMES command. Used to crash if
6569 * Forwarded packets must not be routed even if it is not destined
6570 to the receiver. Changed server code comply with this.
6572 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6574 * Added `require_reverse_mapping' boolean value to ServerParams
6575 structure. If TRUE (not default) the server will require that
6576 the connecting host has fully qualified domain name.
6578 If the reverse mapping is not required and hostname could not be
6579 found the IP address is used as hostname.
6581 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Implemented version string checking to both client and server.
6584 The check is incomplete currently due to the abnormal version
6585 strings used in development version of SILC.
6587 * Changed all command functions in server to use the new
6590 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Changed char *data to unsigned char *data in ID Cache system to
6593 support binary data as ID Cache data. Changed code to support
6594 binary data in lib/silccore/idcache.c.
6596 * Renamed silc_server_packet_relay_command_reply to
6597 silc_server_command_reply as it is normal packet receiving
6598 function. Rewrote the function to accept command replys for
6599 servers and not only for clients.
6601 * Mark remote router always as registered server if we are connecting
6602 to it. Otherwise, commands sent by the router to us are ignored.
6604 * All ID List find routines now returns the ID Cache Entry pointer
6605 as well if requested.
6607 * WHOIS command works now in router environment, tested with two
6608 routers, two servers and two clients.
6610 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6611 in router environment (as it is almost equivalent to WHOIS) but
6612 hasn't been tested thoroughly. Added new functions:
6614 silc_server_command_identify_parse
6615 silc_server_command_identify_send_reply
6616 silc_server_command_identify_from_client
6617 silc_server_command_identify_from_server
6619 * Disabled route cache adding because adding two different ID's with
6620 same IP replaces the old cache entry thus giving wrong route.
6621 The entry->router->connection is always the fastest route anyway
6622 so route cache may not be needed. Of course, new routes maybe
6623 established after receiving the ID when the entry->router->connection
6624 might not be anymore the most optimal.
6626 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Add route cache for received ID for fast routing.
6630 * Added silc_server_packet_route to route received packet on router
6631 that is not destined to us.
6633 * Renamed silc_server_get_route to silc_server_route_get.
6635 * Added id_string and id_string_len fields into SilcServer to
6636 include encoded ServerID for fast comparing without excess
6637 encoding of the ID's.
6639 * Cleaned up WHOIS command on server side. Added following static
6642 silc_server_command_whois_parse
6643 silc_server_command_whois_check
6644 silc_server_command_whois_send_reply
6645 silc_server_command_whois_from_client
6646 silc_server_command_whois_from_server
6648 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6649 arguments in command replies. All command functions should be
6650 updated to use this macro.
6652 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Minor typo fixes on command reply handling on server.
6656 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Added silc_server_command_add_to_channel internal routine to add
6659 the client to the channel after router has created the channel and
6660 sent command reply to the server.
6662 * Added generic silc_server_send_command to send any command from
6665 * Use static buffer with ID rendering instead of duplicating data.
6667 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Fixed a channel user mode bug when joining to a channel server gave
6670 everybody channel founder rights, oops.
6672 * We mark ourselves as the router of the incoming server connection
6673 if we are router ourselves. This way we can check in some packet
6674 sending functions whether it is locally connected server. For
6675 incoming router connections we put NULL.
6677 * For router sending packets locally means now always sending the
6678 packet cell wide; to local clients and local servers. For normal
6679 server sending packet locally means sending it to only local
6682 * Fixed the JOIN command to really work in router environment. If the
6683 channel is created it is always created by the router. Router is
6684 also responsible of making the initial joining to the channel,
6685 sending JOIN notify to the sending server and distributing
6686 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6687 does not exist server doesn't do anything else but forward the
6688 command to the router which performs everything.
6690 * Added silc_server_send_channel_key function to send the Channel Key
6693 * Added silc_server_create_channel_key to create new channel key. The
6694 channel key is now re-generated everytime someone joins or leaves
6695 a channel, as protocol dictates. Note: channel->key_len is the
6698 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6701 packet_receive.[ch] to separate packet sending and receiving
6702 routines. The server.[ch] now includes everything else including
6703 actual packet processing (writing and reading data) and other
6706 Renamed silc_server_private_message_send_internal to
6707 silc_server_send_private_message. The routine is still though
6708 used only to relay private messages as server does not send
6709 private messages itself.
6711 Renamed silc_server_new_channel to silc_server_create_new_channel
6712 and added new function sicl_server_new_channel that handles the
6713 incoming New Channel packet. Added also new sending function
6714 silc_server_send_new_channel to send New Channel Payload.
6716 * Added new function silc_server_notify to process incoming notify
6717 packet to the server/router. Server may then relay the notify
6718 to clients if needed.
6720 * Added new function silc_server_new_channel_user to process incoming
6721 New Channel User packet. Router will redistribute the packet and
6722 send JOIN notify to its local clients and locally connected servers
6723 if needed. Normal server will send JOIN notify to its local client
6724 on same channel when received this packet. Added also corresponding
6725 sending function silc_server_send_new_channel_user to sent the
6728 * Added boolean route argument to send_notif_to_channel and
6729 packet_send_to_channel functions to attempt to route the packet
6730 if it is TRUE and send only locally if it is FALSE.
6732 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * silc_server_replace_id now broadcasts the received replace ID
6735 packet if it is not broadcast packet already. The router must
6736 broadcast to inform other routers about changed ID.
6738 * Added backpointer to server's router into SilcServer context in
6739 silcd/server_internal.h.
6741 * Fixed silc_server_packet_broadcast to send correct broadcast
6744 * The channel key is now distributed to the local client as soon
6745 as it is received from the router (in router environment) so that
6746 no other packet may be sent for the channel until client has
6749 * silc_server_remove_channel_user now broadcasts the received
6750 Remove Channel User packet if it is not broadcast packet already.
6751 The router must broadcast to inform other routers about removed
6754 * Added users field into SilcPacketContext that is a reference count
6755 of the context. One can increase the reference count by calling
6756 silc_packet_context_dup which is now changed to just increase the
6757 reference count instead of duplicating the data. The reference
6758 count is decresed by calling silc_packet_context_free that will
6759 free the data after the reference count hits zero.
6761 For now on the packet context and everything allocated into it
6762 (including the raw packet from network) must be freed by calling
6763 the new silc_packet_context_free function. Added also new function
6764 silc_packet_context_alloc that must be used now to allocate the
6765 context. This also means that if a routine is asynchronous from
6766 silc_[client/server]_packet_parse_type the packet context must
6767 be duplicated by calling silc_packet_context_dup. Otherwise it
6768 gets free'd after silc_[client/server]_packet_parse_type returns.
6769 Also, one must remember that if packet is duplicated then its
6770 reference count must be decresed by calling the free function as
6771 many times as it was duplicated.
6773 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6774 from both client and server.
6776 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Made joining to a channel working in router environment.
6780 * Cleaned up JOIN command on server side and create function
6781 silc_server_command_join_channel internal routine to make the
6784 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Changed silc_command_pending list to SilcDList. Also, added
6787 `ident' field to SilcServerCommandPending structure to identify
6788 the reply and to call correct callback.
6790 Added silc_server_command_pending_check function to replace the
6791 corresnponding macro. The silc_command_pending list is not
6794 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6795 to set identifier to previously allocated Command Payload. It
6796 is used to set identifier for command when resending Command
6799 * Added silc_command_payload_encode_payload to encode Command
6800 Payload buffer from SilcCommandPayload structure.
6802 * Added silc_argument_payload_encode_payload to encode Argument
6803 payload buffer from SilcArgumentPayload structure.
6805 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Changed WHOIS command to support router connection on server side.
6808 The whois request is always sent to router unless the server is
6809 standalone server. After server has received the reply from the
6810 router will it send the reply to the client.
6812 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6813 broadcast received broadcast packet. The function is used only
6814 by router. The broadcast packet is always sent to the router's
6817 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6818 render given ID to printable string, for log files for example.
6820 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6822 * Made basic router to router connections working. At least they
6823 can now connect to each other but nothing really works the way
6824 they are supposed - yet.
6826 * Added new initiator token to RouterConnection configuration
6827 file in silcd/serverconfig.[ch]. It is used to tell whether we
6828 are the initiator to the remote router or whether we'll expect
6829 the other end to connect.
6831 * Moved registering of listener task to silc_server_init, hence
6832 the server starts listenning as soon as it is run, even if it
6833 does not have connections to other routers. Let's see how well
6836 * Changed default connection retry timeouts for more suitable in
6839 * Removed cipher and such arguments from silc_idlist_add_client
6840 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6841 Added new function silc_idlist_add_data to add the keys and stuff
6844 * Added SilcIDListData structure and added it to SilcClientEntry
6845 and SilcServerEntry as their first field in the structure. This
6846 way we can explicitly cast the ID entries to the SilcIDListData
6847 structure and get common data for the entries. In past, we had
6848 to first check what type of connection it is and then cast it to
6849 correct ID entry type. Now, we can directly cast the opaque
6850 pointer to the SilcIDListData (no matter what ID entry it actually
6851 is) and get the data needed.
6853 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6855 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6856 in some circumstances even if threre were timeout tasks, though not
6857 IO tasks, but tasks anyway. Now fixed.
6859 * Defined SilcServerConnection structure to hold connection specific
6860 stuff about directly connected servers and routers. The definition
6861 is currently in silcd/server_internal.h. I thought about having
6862 a bit more important role fro this struct but for now it is used
6863 only when connecting to other server (or router actually).
6865 * Added connecting retry support in server when connecting to
6866 router(s). The retry feature implement exponential backoff
6867 algorithm. Also, added SilcServerParams structure to hold default
6868 parameters for server. For now, it include these retry settings
6869 and are hard coded. After server is moded to be as Silc Server
6870 Library this structure will be more important.
6872 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Changed client librarys channel->clients table to SilcList and
6875 changed code accordingly.
6877 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * Changed client's channel table to SilcList and changed code
6880 accordingly. Also changed SilcChannelClientEntry to include back-
6881 pointer to the channel so that client entry can use that structure
6882 as list as well and we have fast cross-reference to the channel.
6883 This change dramatically decreased the complexity of channel
6884 handling with client entry and vice versa (removed one extra
6885 loop when searching for channel entry from many functions).
6887 * Changed server->sim from table to SilcDList and changed code
6890 * NAMES command can now be used from user interface. It will show
6891 the user list on the channel, neatly.
6893 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6894 Code now saves realname of the user if it becomes available.
6896 * Renamed configure.in to configure.in.pre and made ./prepare
6897 script to automatically add correct version string to
6898 configure.in which it creates from configure.in.pre.
6900 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * NAMES command reply now shows users mode with the nickname when
6905 * Moved silc_client_ch[u]mode[_char] functions from
6906 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6907 place sucks, they are utility functions and should be in some
6910 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6912 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6915 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Added TRQ (efficient deque and list library) into lib/trq. This is
6920 a very good list library that is currently used in the SILC. Defined
6921 SilcList API over the library because I didn't like the API very
6922 much. See lib/trq/silclist.h for the API and examples of how to
6923 use the API. Fixed various places in the code to use the new
6924 SilcList API. The SilcList is meant for lists that has a structure
6925 already defined as a list. It is not suitable to add just some
6926 context to the list (in TRQ, the context is the list actually).
6928 So, I defined SilcDList that can be used for the purpose where
6929 predefined list structure does not exit. This can be used as
6930 such list. Now some context just can be added to the SilcDList.
6931 Currently this list is not used in the SILC just yet, though there
6932 are a lot places where this can replace dynamically allocated
6933 tables and I will fix these places, later, to use SilcDList.
6934 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6935 and use TRQ internally).
6937 Also fixed some annoying warning messages that the original TRQ
6938 code generated. Also minor changes to TRQ's Makefile.in.
6940 * Added support for querying by Client ID to both WHOIS and
6941 IDENTIFY commands into server, as required by the protocol.
6943 * Removed method function pointers from SilcBuffer structure. They
6944 weren't used to anything and just increased the context size for
6945 no good reason. This change also made silc_buffer_alloc and
6946 silc_buffer_free functions inline functions.
6948 * Disabled command flooding detection support until it's fixed so
6949 that it accepts commands in but does not execute them more than once
6952 * Added silc_net_localhost(), to return local hostname, into
6953 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6954 that must be initialized before calling silc_client_init.
6956 * Added new function: silc_server_send_notify_on_channels to send
6957 notify messages to all channels client has joined. It is assured
6958 that the message is sent only once per client.
6960 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6961 lib/silcutil/silcutil.[ch] as silc_format function. The new
6962 function is generic and is used by server as well, not only by
6963 the logging routines.
6965 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6966 the provided version string was not acceptable. Added new function:
6967 silc_ske_check_version into lib/silcske/silcske.h. The function
6968 must be implemented by the application (client or server) and it
6969 does not reside in the SKE library. The function checks the version
6970 string remote end sent.
6972 * Added back pointers (to opaque context and to SilcSocketConnection)
6973 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6975 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6976 duplicate packet context structure.
6978 * Changed `notify' client operation to send same arguments as client
6979 receives from server except for ID's. ID's are mapped to correct
6980 ID entry and that is returned. Also, if channel entry is not sent
6981 by server but the notify is for channel the channel entry is sent
6982 to application (otherwise application doesn't know that it is for
6983 channel (library gets it from packet's Destination ID)).
6985 * Added silc_client_remove_from_channels into client library to
6986 remove a client from all channels it has joined to. Used when
6987 received SIGNOFF notify from server. Added also new function
6988 silc_client_replace_from_channels to replace old ID entry with
6989 new ID entry on all channels. Used when received NICK_CHANGE
6992 * Fixed ID Cache list handling in silc_idlist_get_client in
6993 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6994 to get (or query) client by ID.
6996 * Updated TODO list.
6998 * Added connection authentication status message defined by the
6999 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7000 support for these into the code in client and server side.
7002 * Added generic function silc_client_send_command to send any command
7003 with variable argument list. Application should use this function
7004 to send commands if the command functions provided by the library
7005 does not suite for the application's user interface needs.
7007 * Added new `failure' client operation. Application is notified about
7008 received failure packet if client is executing a protocol. In this
7009 case the protocol's execution has failed.
7011 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7012 is required by the protocol.
7014 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7015 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7018 * Added status flag to SilcSKE object to indicate realtime status
7019 of the SKE protocol.
7021 * Application receives now exactly same command reply arguments as
7022 the library receives from server. However, if ID is received the
7023 corresponding ID entry is returned to the application (eg. Client
7024 ID is mapped to correct SilcClientEntry entry and that is returned).
7025 Changed command_reply client operation due to this change.
7027 * Changed all ID's in commands and in command replys as ID Payloads.
7028 Change affected both client and server side codes.
7030 All ID's sent in SILC network (with execption of ID's in SILC
7031 Packet header) are sent in ID Payload to support variable length
7034 * Server now notifies nick changes and notifies all clients on
7035 the channels about the new nickname (about the new Client ID,
7038 * Implemented CMODE command to change channel modes. Supports all
7039 channel modes defined by the protocol specs except ban and invite
7040 lists. (Also, private channel key mode is supported but support for
7041 setting private channel key in client is missing, thus, this mode
7042 has no effect on client side (except that server requires that the
7043 client uses private channel key and normal channel traffic does not
7046 Also, invite mode works per se, but INVITE command does not work
7047 yet correctly, so you can set channel as invite only channel but
7048 inviting clients to the channel does not work (it is yet to be
7049 thought what's the best way to do it).
7051 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7052 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7053 Implemented CUMODE command to change user's mode on the channel.
7054 Supports all modes defined by the protocol specs.
7056 * Added NAMES command reply to return users modes on the channel.
7058 * Removed unnecessary and slow ciphers from lib/silccrypt.
7060 * Set SO_KEEPALIVE option to connection sockets by default.
7062 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7064 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7065 redefined the Notify Payload into protocol specs.
7067 * Added silc_id_payload_parse_id to get ID directly from raw
7070 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7073 accept searching by Client ID as well.
7075 * Added support for LEAVE and SIGNOFF notify types in client library.
7077 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7078 to parse ID Payload from raw data.
7080 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7082 * Added flags parameter into silc_ske_assemble_security_properties
7083 function in lib/silcske/silcske.[ch].
7085 * Changed notify client operation to fit better for notify messages
7086 sent by server. The notify payload received from server is now
7087 passed to the application (after parsing it to SilcNotifyPayload).
7088 It is application's responsibility to retrieve the arguments
7089 from the payload and show the message the way it wants. The message
7090 sent by server is implementation specific.
7092 * Changed public keys to comply with the protocol specification.
7093 Old public keys are not supported anymore and are not compatible.
7095 * Removed nickname from Channel Payload as the latest draft removed
7096 it. The client must resolve the nickname from the NAMES command
7097 reply received when it joined the channel.
7099 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7101 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Fixed some errors in protocol specification drafts.
7105 * Created lib/silccore/silcnotify.c to implement Notify Payload
7106 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7107 generic payloads described by protocol specifications. The file
7108 includes implementations for ID Payload and Argument Payload.
7110 * Changed Command Payload implementation to use the new Argument
7111 Payload. Changed command_xxxx_payload to command_payload_xxxx
7112 to comply with SILC coding conventions.
7114 * Added suppport for Argument Payload handling in Notify Payload
7115 implementation as protocol requires it. Added the new support
7116 into server and client lib as well.
7118 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Added support for multiple nicknames on same channel. [n] is
7121 added locally to the nickname if there are more than one same
7122 nicknames on the channel.
7124 * Server now sends all nicknames that matched WHOIS request.
7125 Client also shows the list received from server.
7127 * Added TOPIC command to client side. User can now set and show
7128 current topic on channel.
7130 * Added MOTD command to client and server. Also, server sends the
7131 motd when client connects to the server.
7133 * Changed version strings to comply ISO 8601.
7135 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Fixed protocol error handling in client library. It should now
7138 cope even if the SKE fails for some reason.
7140 * Made new protocol specification drafts for submitting to IETF.
7142 * Implemented TOPIC command to server in silcd/command.c.
7144 * Added two new notify types into lib/silccore/silcnotify.h:
7145 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7146 notify nickname change and topic setting/change on a channel.
7148 * API change of command_reply operation in client library. The
7149 application gets now the status type received from server as well.
7151 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7155 * Cras fixed and optimized the packet handling even further and
7156 it should work now. Minor change to the prototype of function
7157 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7159 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Added new function into lib/silcutil/silcschedule.[ch]:
7162 silc_schedule_with_fd to select() a specified fd. The function
7163 returns after timeout expires or data arrives or goes. The
7164 function is used by packet routines to wait that all data is
7165 received from network.
7167 * Fixed data reading from network in lib/silccore/silcpacket.c.
7168 The code now assures that all data is read from the fd and then
7169 continues packet processing. This was a bug fix since the code
7170 used to drop some data in some circumstances.
7172 * Added new function into lib/silcclient/client.[ch]:
7173 silc_client_start_key_exchange to start key exchange after
7174 connection has been established to server. The code internally
7175 now uses this funtion but its main purpose was to provide it
7176 for applications that perform their own connecting. After
7177 application has created a connection it merely calls this
7178 function to start the key exchange between client and server.
7179 The library takes care of everything else after that.
7181 Updated also lib/silcclient/README to explain the usage of
7184 * Do not send to application information that connection has
7185 been established. Application gets notified it by connect
7188 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Applied cras's patch to add silc_schedule_one function. The
7191 function runs scheduler once and returns.
7193 * Fixed the scheduler after cras messed it up. The timeout
7194 handling works now as it's supposed to work.
7196 * Added into lib/silccore/ silcnotify.h to include notify
7197 message types support. Changed silc_server_send_notify*
7198 functions, in server.[ch], to support those new notify types.
7199 Added the support for the notify types into client library,
7200 as well. Added new notify client operation into ops.h in
7203 * Changed silc_server_packet_send_to_channel to send normal
7204 packets instead of just channel message packets. The function
7205 is now used to send the notify packets to channels. It is not
7206 used to send channel message packets anymore, as server never
7209 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7210 va_arg()s as it seems to require it nowadays. I guess, if SILC
7211 is compiled with older va_arg() the new code should work anyway.
7213 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7215 * Splitted core library. Core library (lib/silccore) includes
7216 now only SILC protocol specific core (and common) components.
7217 Created new utility library (lib/silcutil) that includes more
7218 generic purpose stuff. The stuff for util library was taken
7219 from the old core library. This was minor and easy split.
7221 * Created SILC Client Library (lib/silcclient) that includes
7222 implementation of the SILC client without user interface. This
7223 was major move from silc/ directory. The code has been changed
7224 so that it is transparent towards the user interface. The
7225 silc/ directory includes now the same user interface as before
7226 and it uses the new client library. Read lib/silcclient/README.
7227 Basicly, the client library performs everything else related
7228 to SILC except user interface handling. Also, configuration
7229 files are considered to be part of user interface and library
7230 does not handle them.
7232 This change also changed a lot of structures, function naming etc.
7233 Most important change was that SilcClientWindow object was
7234 renamed to SilcClientConnection in the client library. Created
7235 also new file lib/silcclient/ops.h. Also added new files
7236 silc/local_command.[ch] and silc/client_ops.[ch].
7238 All these changes were made to make it easier for user interface
7239 designers to create what ever user interface for the SILC client
7242 It is also expected that the server will be moved to lib
7243 directory as well and SILC Server Library will be created;
7244 sometimes in the future.
7246 * Removed Local commands from lib/silccore/silccommand.h as
7247 they are application specific and new client library does not
7248 handle any of those anymore.
7250 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7251 old client implementation in silc/.
7253 * Added support for callback functions in SILC_LOG_* macros.
7254 Application can now set its own callbacks that will be called
7255 instead of using the default functions that will always print
7256 the debug messages to stderr (or stdout). Also, debugging can
7257 now be disabled by setting silc_debug to FALSE and re-enabled by
7258 setting it to TRUE. Note, that logging will still work even
7259 if debugging is disabled.
7261 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7262 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7263 silc_log_reset_debug_callbacks.
7265 * To enable debugging in silc client one must give now -d
7266 option on command line.
7268 * Changed silc_schedule_init to automatically allocate task queues
7269 if they are not allocated before calling it.
7271 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * Added GMP 3.1 into math library.
7275 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7277 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7278 a channel in SILC network. The packet is used by servers and
7279 routers to notify other routers that user has left a channel.
7280 This little feature was missing until now. Added the feature
7281 to protocol specification as well.
7283 Added functions: silc_server_send_remove_channel_user and
7284 silc_server_remove_channel_user into server.[ch].
7286 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7287 lib/silccore/silcpacket.h. However, they are not implemented
7290 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Fixed joining to a channel and sending channel messages
7293 between server and router. The channel message sending should
7294 now work inside a cell.
7296 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Fixed the private message sending between server and router.
7299 The private message sending should now work inside a cell.
7301 * Added silc_server_replace_id into server.[ch] to replace
7302 existing ID in the SILC network.
7304 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7305 and silc_idlist_replace_server_id into idlist.[ch] in server.
7307 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Fixed the server to server connections. Server can again now
7310 connect to router. Router to router connections probably does
7313 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7315 * Added dynamic protocol registering support. Now protocols can
7316 registered and unregistered on the fly. Patch by cras.
7318 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Added lib/contrib directory to hold routines that some platforms
7321 don't have but are needed by SILC.
7323 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7324 into lin/contrib to provide getopt() and getopt_long() for
7325 those who don't have it.
7327 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7329 * Added AWAY command to client. When away message is set and
7330 client receives a private message packet the client automatically
7331 replies to the sender with the away message.
7333 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7334 bug seemed to be the cause of recent problems when compiling
7337 * Added version detection support to SKE protocol specification
7338 and added the new changes to the SKE implementation as well.
7339 There were other minor changes in the SKE protocol as well.
7341 Many changes in lib/silcske/silcske.[ch] and in
7342 lib/silcske/payload.[ch].
7344 * Added ^U functionality, clear input line. Patch from cras.
7346 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Mainly small bugfixes on core library. Fixed some debugging
7349 logging and buffer overflow in silclog.c.
7351 * Updated config.sub and config.guess on the distribution tree.
7353 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7355 * Added command lagging support in server. Client may execute
7356 commands now only once in two seconds.
7358 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7360 * Optimized packet reception. MAC computation and checking is now
7361 also more optimized. A lot previously duplicated code is now
7362 used as generic by both client and server.
7364 * Fixed key pair generation in clientutil.c
7366 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7368 * Added into lib/silccore/silcbufutil.[ch] new function;
7369 silc_buffer_realloc.
7371 * Moved generic packet sending/encryption functions to
7372 lib/silccore/silcpacket.[ch] from client and server. Some
7373 rewriting of the functions.
7375 * Moved all generic packet reception/decryption functions to
7376 lib/silccore/silcpacket.[ch] from client and server. The
7377 packet processing is now much cleaner in both client and server.
7378 These were major changes in both client and server.
7380 * Created many common functions in server to do packet sending.
7381 Previously code were duplicated a lot, this has been removed
7384 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Rewrote major parts of the ID cache system. Don't know
7387 whether it is better now or not but at least the API is more
7390 * Major rewrite on ID cache stuff on client because of the ID
7391 cache API changes. Added idlist.c to client.
7393 * Also major rewrite on ID cache stuff on server as well.
7394 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7395 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7396 in hand, instead they are all put into the ID cache system now.
7397 All server_idlist_* routines uses ID cache now instead of
7398 traversing its own lists (those lists does not exist anymore).
7399 SilcIDList though still exists. Also, SilcXXXEntry's are
7402 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7404 * Finally made the SKE implementation compliant to the protocol
7405 specification. All mp integers are now binary encoded as
7406 opposed being HEX encoded.
7408 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7411 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7412 functions: silc_[encode/decode]_pem. Also added function
7413 silc_encode_pem_file to PEM encode with newlines ('\n') for
7416 * SILC public keys are now encoded either PEM or binary. Same
7417 option is for private keys as well. By default private keys
7418 are binary encoded and public keys PEM encoded. Silly HEX
7419 encoding were removed.
7421 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7422 function to create fingerprints.
7424 * Fixed a bug in SHA1; does not change the original data anymore.
7426 * Partly implemented INFO command on client and server side.
7427 Fixed CLEAR command. Changes to SERVER command; show current
7428 server(s) when giving command without arguments. Added
7429 VERSION command to client.
7431 * Added check to server that unregistered connections cannot
7432 execute commands (unless it is specificly allowed).
7434 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Fixed screen refresh.
7438 * Fixed channel joining bug from client. On some circumstances
7439 client tried to join to a channel it had already joined.
7441 * Added public key verification process into client's protocol.c.
7442 The client now verifies the public key from user and saves
7443 it into ~./silc/serverkeys/ directory.
7445 Added into: clientutil.[ch]: silc_client_verify_server_key.
7447 * Changed SKE protocol's silc_ske_initiator_finish function
7448 to accept callback function that verifies the received public
7449 key. Removed old silc_ske_verify_public_key function.
7451 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7454 silc_pkcs_private_key[_data]_set.
7456 * Made the password and public authentication more cleaner in
7457 server's protocol.c.
7459 * Removed historic and obsolete protocol `channel_auth' from
7460 both client and server.
7462 * Removed wrong way of sending command status messages from
7463 server to client in server's command.c. The old way violated
7464 protocol specification.
7466 Changes to silccore/silccommand.[ch]: removed
7467 silc_command_encode_status_payload -> not needed anymore,
7468 changed silc_command_encode_payload_va to accept extra
7469 argument on variable argument list. The argument type must
7470 now be provided to the function. Also, added new function:
7471 silc_command_encode_reply_payload_va which is same as
7472 normal command_encode_payload_va except command status type
7473 is provided as extra argument.
7475 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Added ~./silc directory handling. The directory includes the
7478 public and private keys for the client.
7480 Added silc_client_check_silc_dir, silc_client_create_identifier
7481 and silc_client_load_keys.
7483 * Implemented SILC protocol compliant public key. Added public
7484 and private key saving to and loading from files.
7486 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7487 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7488 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7489 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7490 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7492 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7493 silc_pkcs_load_[public/private]_key.
7495 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Added silc_server_get_route (route.[ch]) to get connection
7498 data for the fastest route for given ID.
7500 * Implemented INVITE command on client and server. The command
7501 were re-defined in the SILC Protocol Specification and the
7502 implementation now complies with the specification.
7504 * Implemented PING command on client and server.
7506 * Implemented NAMES command on client and server. The server side
7507 supports currently only normal server not router server yet.
7508 Some changes to NAMES definition in SILC protocol specification.
7510 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7512 * Implemented LEAVE command on client and server.
7514 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
