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

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

296 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Added automatic extern "C" { ... } for C++ compilers so the
299 application does not need to define them. Affected file
300 includes/silcincludes.h.
302 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
303 old name went against naming convention. Applications now
304 include "silcclient.h" instead of "clientlibincludes.h".
305 Removed includes/clientlibincludes.h, it is redundant now.
307 * Renamed includes/version.h to silcversion.h.
309 * Added really preliminary support for OS/2 into the util
310 library. Only thread & mutex API is implemented, others
311 are still to be implemented. Created the lib/silcutil/os2/
312 directory. Created also file includes/silcos2.h.
314 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
316 * Added preliminary BeOS support into the util library.
317 Created lib/silcutil/beos/, and implemented all the needed
318 functions to support SILC on BeOS. Created also file

323 * Added proper initializations to silc's irssi code, so it's
324 now possible to load it as module. Affected files
325 irssi/src/silc/core/silc-core.c,
326 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
328 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

514 * The silc_cipher_register, silc_hash_register and
515 silc_hmac_register now checks if the object to be registered
516 is registered already. Affected files are
517 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
519 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

537 * Fixed CUMODE_CHANGE notify handling to change the mode of
538 correct client. Affected file lib/silcclient/client_notify.c.
540 * Make silc_rng_alloc fail if it cannot allocate the sha1
541 hash algorithm. Affected file lib/silccrypt/silcrng.c.
543 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
545 * Fixed the file transfer's key agreement payload to include
546 zero port also if the hostname is NULL because it could not
549 Call file transfer monitor callback now also if error occurs
550 during key agreement protocol.
552 Changed the silc_client_file_send interface to return the
553 SilcClientFileError instead of session id. The session ID
554 is returned into pointer provided as argument.
556 Check that the file exists locally before sending the
557 file transfer request at all.
559 Affected file lib/silcclient/client_ftp.c, silcapi.h.
561 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
562 error than can occur while key agreement protocol. Affected
563 file lib/silcclient/silcapi.h.
565 * Fixed the event_mode CMODE handler to not crash when mode
566 is changed and +k mode is set in the channel. Affected file
567 irssi/src/silc/core/silc-channels.c.
569 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
570 SILC_LOG_WARNING to give out Warning and not Error. Affected
571 file lib/silcutil/silclog.c.
573 * Fixed the channel message payload decryption in the function
574 silc_channel_message_payload_decrypt to not modify the original
575 buffer before it is verified that the message decrypted
576 correctly. Otherwise, next time it is called with correct
577 channel key it won't encrypt since the payload is corrupted.
578 Affected file lib/silccore/silcchannel.c.
580 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
582 * Do not constantly resize the window. A fix patch by cras.
583 Affected file irssi/src/fe-text/screen.c.
585 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
588 Affected file lib/silcutil/silcnet.c.
590 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Fixed a bug in hash table internal routine for traversing
593 the table with foreach callback. The current entry may
594 become invalid in the callback but it was referenced after
595 the callback returned.
597 Do not allow auto rehashing of hash table during the
598 silc_hash_table_foreach operation, for same reasons as it is
599 not allowed for SilcHashTableList. Affected files are
600 lib/silcutil/silchashtable.[ch].
602 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Defined DLLAPI into silcincludes.h and silcwin32.h for
605 Win32 DLL. extern's in header files are now declared with
608 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Fixed private message handling. It used some old code that
611 caused the client to crash. Affecte file is
612 lib/silcclient/client_prvmsg.c.
614 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
616 * Added function silc_client_add_channel,
617 silc_client_replace_channel_id, and removed functions
618 silc_client_new_channel_id and silc_idlist_get_channel_by_id
621 * Added cross reference of the joined channels to the
622 SilcClientEntry, and changed the SilcChannelEntry's
623 users list to SilcHashTable. The affected files are
624 lib/silcclient/idlist.[ch].
626 * Fixed a bug in hash table tarversing. While the hash table
627 is traversed with SilcHashTableList the table must not be
628 rehashed. It is now guaranteed that auto rehashable tables
629 are not rehashed while tarversing the list. Also defined that
630 silc_hash_table_rehash must not be called while tarversing
631 the table. Added function silc_hash_table_list_reset that must
632 be called after the tarversing is over. The affected files are
633 lib/silcutil/silchashtable.[ch].
635 * Changed all hash table traversing to call the new
636 silc_hash_table_list_reset in server and in client library.
638 * Added function silc_client_on_channel to return the
639 SilcChannelUser entry if the specified client entry is joined
640 on the specified channel. This is exported to application as
641 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
643 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Fixed founder regaining problem with JOIN command on normal
646 server. The notify for mode change must be sent always and
647 not only if !cmd->pending. Affected file silcd/command.c.
649 * Fixed the WHOWAS command's reply sending to support the
650 lists correctly. Affected file silcd/command.c.
652 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * When sending JOIN command to router for processing the
655 sender's old command identifier was not saved back to the
656 sender's command context, fixed now. The affected file is
659 * Create the key in JOIN command of the router did not return
660 the channel key, added check for this. Affected file is
663 * Fixed a channel ID update bug in JOIN command reply. Do
664 not directly upgrade the ID but call the function
665 silc_idlist_replace_channel_id if the ID was changed.
666 Affected file silcd/command_reply.c.
668 * Fixed memory leaks from command calling if it would fail.
669 Affected file silcd/command.c.
671 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
673 * Applied patches from cras:
675 Memory leak fixes around libaries, irssi window resize fix,
676 new silclist.h and silcdlist.h, all extern inline changed to
679 * Removed dotconf from lib/dotconf, not needed anymore.
681 * Removed TRQ from lib/trq, not needed anymore.
683 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
684 with server connections. Later this will be configurable
685 in config file after new config file is done. Affected file
688 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
690 * Fixed a crash in server related to channel announcements.
691 Affected file silcd/server.c.
693 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Fixed memory leaks in silc_server_create_new_channel*
696 functions. Affected file silcd/server.c.
698 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
699 which ID was changed. This way the router will send the
700 user list for the channel again, and server won't be in
701 desync in some rare circumstances. Affected file is
702 silcd/packet_receive.c.
704 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Check for NULL socket pointer in the function
707 silc_server_packet_send_to_channel_real. Affected file
710 * Fixed the BAN notify handling to correctly remove ban
711 list. Affected file silcd/packet_receive.c.
713 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
715 * Fixed some header addition to Toolkit distribution in
716 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
718 * Added lib/silcclient/client_ops_example.h as an template
719 file for application programmers to quickly start using
720 the SilcClientOperation functions in their application.
721 Updated the lib/silcclient/README as well to tell about this
722 nice file made available.
724 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
726 * Call silc_server_remove_from_channels when removing client
727 entry when NO_SUCH_CLIENT_ID was received. Affected file
728 is silcd/command_reply.c.
730 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
732 * Added server & router operator statistics updating. Affected
733 file silcd/packet_receive.c and silcd/command.c.
735 * Fixed the SERVER_SIGNOFF notify handling on normal server
736 not to save the history information for clients. Same was
737 fixed earlier in remove_clients_by_server function, but not
738 here. Affected file silcd/packet_receive.c.
740 * Raised the default connection-retry count from 4 to 7 in
741 server. Affected file silcd/server.h.
743 * Cancel any possible reconnect timeouts when we start the
744 key exchange. Affected file silcd/server.c.
746 * Do not reconnect on connection failure when SCONNECT was
747 given. Affected files silcd/server.[ch].
749 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
751 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
753 * Fixed the NICK command to always give the unformatted
754 nickname to the one giving the NICK command. If unformatted
755 nickname is cached already it will be formatted and the
756 local entry will always get the unformatted nickname.
757 Affected file lib/silcclient/idlist.c.
759 * Fixed some double frees from client library commands.
760 Affected file is lib/silcclient/command.c.
762 * Fixed CUMODE command in server to assure that no one can
763 change founder's mode than the founder itself, there was a
764 little bug. Affected file silcd/command.c.
766 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
768 * Removed the SilcClientCommandDestructor from the client
769 libary, it is not needed anymore. Affected files are
770 lib/silcclient/silcapi.h, command[_reply].[ch],
771 client_notify, idlist.c.
773 * Fixed GETKEY command to first resolve client, and then
774 resolve the server only if the client was not found, instead
775 of resolving both at the same time. Affected file is
776 lib/silcclient/command.c.
778 * Added silc_client_start_key_exchange_cb and lookup the
779 remote hostname and IP address before starting the key
780 exchange with server. The affected file is
781 lib/silcclient/client.c.
783 * The server's public key is now saved using the IP address
784 of the server and not the servername for the filename.
785 The hostname public key filename is checked as an fall back
786 method if the IP address based filename is not found.
788 Fixed the GETKEY command to save the fetched server key
791 Print the remote server's hostname now when new key is
792 received during connection process. Affected file is
793 irssi/src/silc/core/client_ops.c.
795 * Return always our own public key to the client if it asks
796 for it with GETKEY command. Affected file silcd/command.c.
798 * Removed the use_auto_addr variable from default config
799 file since it was in wrong section. Affected file is
802 * Fixed TOPIC_CHANGE notification to not route it when it
803 was sent using silc_server_send_notify_to_channel function.
804 Affected file silcd/command.c.
806 * Fixed silc_server_send_notify_kicked to send the kicker's
807 Client ID also, it was missing. Affected files are
808 silcd/command.c, silcd/packet_send.[ch].
810 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
812 * Do not save client history information in SERVER_SIGNOFF.
813 Fixes the bug in normal server that it does not detect
814 the client becoming valid after the server becomes back
815 online. Affected file silcd/server_util.c.
817 * Added `sock_error' field into the SilcSocketConnection
818 context. When error occurs during socket operation (read
819 or write) the error is saved. Added also new function
820 silc_socket_get_error to return human readable socket error
821 message. Affected files are lib/silcutil/silcsockconn.[ch],
822 lib/silcutil/unix/silcunixsockconn.c, and
823 lib/silcutil/win32/silcwin32sockconn.c.
825 * The server now prints the socket error message in the
826 signoff for client. Affected file silcd/server.c.
828 * Fixed the `created' channel information sending from router
829 to server in JOIN command. Checks now whether the channel
830 really was created or not and set it according that.
832 Fixed the JOIN command to use the client entry's current
833 ID during the joining procedure instead of the one it sent
834 in the command (it is checked though), since it can change
835 between the packet processing and command processing, and
836 would just case unnecessary pain in the client end. Affected
837 file silcd/command.c.
839 * Fixed a channel key payload sending to use correct channel
840 ID when the server was forced to change the channel's ID by
841 router. Router sent the key payload with the old Channel ID.
842 Affected file silcd/packet_receive.c.
844 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
846 * Call silc_server_save_channel_key only if the key payload
847 was provided in the JOIN command's command reply. Affected
848 file silcd/command_reply.c.
850 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
852 * Fixed silc_mp_sizeinbase to return the value correctly with
853 MPI. Affected file lib/silcmath/mp_mpi.c.
855 * Fixed the stop_server signal to correctly stop the scheduler
856 and gracefully stop the server when SIGTERM or SIGINT signals
857 are received. Affected file silcd/silcd.c.
859 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
861 * Simple handling of TERM and HUP signals. Also added some log
862 flushing call around. Affected file is
865 * Fixed small bugs in silclog.c. Now buffering output will take
866 effect after 10 seconds since startup: This will ensure that
867 no important startup messages are lost. Also output redirection
868 will preserve original format ([Date] [Type] message).
869 Affected file is lib/silcutil/silclog.c.
871 * Added two options to the config file, in the logging section:
872 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
873 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
875 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Do not print the warning about log files not being initialized
878 more than once to avoid excess logging. Affected file is
879 lib/silcutil/silclog.c.
881 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
882 the SIM copying in make install in Makefile.am.pre.
884 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
886 * Rewritten silclog APIs. Globally interesting changes follows:
887 silc_log_set_files() changed to silc_log_set_file().
888 silc_log_set_callbacks() changed to silc_log_set_callback().
889 ROBOdoc documented silclog header file.
890 SilcLogCb now returns bool to wether inihibit the default
891 handler or not (to keep the old behaviour return always TRUE).
892 The new APIs should also fix the problem of the
893 silcd_error.log file that was written in the current directory.
896 Log files streams will remain opened after silc_log_set_file()
897 call, means less CPU usage notably on high traffic servers.
898 File streams are now full buffered, and flushed to the disk
899 every 5 minutes, lesses HD activity and CPU usage.
900 Messages can be redirected, allowing admins to configure
901 one single logfile for all server messages.
902 the silc_log_quick global variable to activate fast-logging.
903 Affected files lib/silcutil/silclog.[ch]
905 * Changed some code to conform new silclog APIs. Affected
906 files are doc/example_silcd.conf.in, silcd/server.c
907 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
910 * Fixed a memory leak that could occur in some situations.
911 Affected file silcd/serverconfig.c.
913 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
915 * Added the silc_client_del_client to remove the client from
916 all channels as well. Affected file lib/silcclient/idlist.c.
918 * Fixed the client library to correctly remove the client
919 from all channels when the client entry is being destroyed.
920 Affected file lib/silcclient/client_notify.c, command.c.
922 * Added auto-nicking support to the client library. If the
923 applicatio now sets client->nickname it will be sent to the
924 server after connecting by the library. This way for example
925 SILCNICK (or IRCNICK) environment variables will have effect
926 and always change the nickname automatically to whatever
927 it is wanted. Affected file lib/silcclient/client.[ch].
929 * Renamed silc_server_command_bad_chars to the
930 silc_server_name_bad_chars and moved it to the
931 silcd/server_util.[ch]. Added also new function
932 silc_server_name_modify_bad to return nickname that
933 includes bad characters as new nickname without those
934 bad characters. This check and modify is now used in
935 silc_server_new_client when the username is initially set
936 as nickname, so it must be checked to be valid nickname.
937 Affected file silcd/packet_receive.c.
939 * The nickname length is now taken from the packet for real
940 and not trusted to strlen() since it clearly can return
941 wrong length for nickname including bad characters. This
942 also applies to channel names. Affected file silcd/command.c.
944 * Removed the lib/silcsilm/modules directory. Modules are now
945 compiled into the lib/silcsim. Fixed the copying of the
946 modules to follow symbolic links in Makefile.am.pre.
948 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
950 * Fixed silc_string_regexify list creation. Fixes bugs with
951 BAN and INVITE commands in server. The affected file is
952 lib/silcutil/unix/silcunixutil.c.
954 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Removed the command destructor entirely from the server's
957 command and command reply routines. It is not needed, and
958 its usage was buggy and caused crashes. Affected files are
959 silcd/command[_reply].[ch].
961 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
963 * Cancel protocol and NULL sock->protocol if timeout
964 occurred during protocol. Affected file silcd/server.c.
966 * Cancel protocol timeouts always before calling the final
967 callback, to assure that after final callback is called
968 no other state will be called for the protocol anymore.
969 Affected file silcd/protocol.c.
971 * Print error log if incoming connection configuration could
972 not be found. Affected file silcd/server.c.
974 * Fixed JOIN command to correctly save the founder mode
975 to the client on normal SILC server, when the channel
976 was created by the router. Affected file silcd/command.c.
978 * Fixed LIST command (hopefully) to send correct reply
979 packets. Affected file silcd/command.c.
981 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
983 * The silc_packet_receive_process now returns FALSE if the
984 read data was invalid packet, and TRUE if it was ok.
986 The server now checks that if unauthenticated connection
987 sends data and its processing fails the server will close
988 the connection since it could be a malicious flooder.
990 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
992 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Make sure the warning about error opening a log file is
995 printed only once and not everytime it fails (produces
996 too much useless log). Affected file lib/silcutil/silclog.c.
998 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1000 * Made the silc_server_daemonise() function more readable.
1001 Affected file silcd/server.c.
1003 * Pid file is now optional, the user may comment it out from
1004 the config file. Removed define SILC_SERVER_PID_FILE, we
1005 don't need a default any longer. Affected file
1006 configure.in.pre, lib/Makefile.am.pre.
1008 * Make some use of the pid file. The server now dies at startup
1009 if it detects a valid pid file on his path. The server would
1010 die anyway in this circumstance, because of the bind() failure.
1011 Affected file silcd/silcd.c.
1013 * No longer compiling lib/dotconf.
1015 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Fixed JOIN command parsing not to crash. Affected file
1018 lib/silcclient/command.c.
1020 * Fied the NICK_CHANGE notify to add the new client entry
1021 even it is resolved. This removes an <[unknown]> nick
1022 thingy bug in the client. Affected file is
1023 lib/silcclient/client_notify.c.
1025 * Do not try to allocate 0 bytes (efence does not like it)
1026 in lib/silccore/silccomand.c when encoding payload.
1028 * Do not take IRCNICK as nickname in Irssi SILC client since
1029 it is not possible to set nickname before hand connecting
1030 the server (TODO has an entry about adding auto-nicking
1033 * Changed the silc_server_command_pending to check whether
1034 there already exists an pending entry with the specified
1035 command, command identifier and pending callback. This is
1036 to fix IDENTIFY and WHOIS related crashes that may register
1037 multiple pending commands with same identifier. Affected
1038 file silcd/command.c.
1040 * Fixed the server to reconnect to the router even if it
1041 was already reconnecting and EOF was received. This to
1042 fix a possibility that the server wouldn't ever try to
1043 auto-reconnect to the router. Affected file silcd/server.c.
1045 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Fixed the server's password authentication to use the
1048 length of the locally saved password, and not the one
1049 sent in the packet. Affected file silcd/protocol.c.
1051 * Fixed same password authentication problem in the
1052 Authentication Payload handling routines in
1053 lib/silccore/silcauth.c.
1055 * Yet another password authentication problem fixed with
1056 channel password handling in silcd/command.c.
1058 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1060 * If first character of string in silc_parse_userfqdn is '@'
1061 then do not parse it. Affected file is
1062 lib/silcutil/silcutil.c.
1064 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1066 * Fixed minor bug in IDENTIFY command reply sending, which
1067 caused various weird problems during JOIN when it was
1068 resolving names for users. Affected file silcd/command.c.
1070 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1072 * Fixed the IDENTIFY command reply sending to chech better valid
1073 clients. It was possible to send incomplete list of replies.
1074 Affected file silcd/command.c.
1076 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Added silc_client_command[s]_[un]register functions now to
1079 dynamically register the commands in client library. Removed
1080 the static table of commands. This allows the client library
1081 to call commands without causing the application to know about
1082 what commands library has called.
1084 Removed the INFO command reply kludge to detect when the command
1085 was called by library. Now library use its own command reply
1086 function for INFO command.
1088 Added function silc_client_command_call to call a command.
1089 Application can use it to call command, not access the structure
1092 Now all commands that are sent by the client library (not
1093 explicitly sent by application) use own command reply functions.
1095 Affected files around lib/silcclient/ and in
1096 irssi/src/silc/core/.
1098 * Fixed the WHOIS command reply sending to chech better valid
1099 clients. It was possible to send incomplete list of replies.
1101 Fixed the WHOIS and IDENTIFY to send the request to router
1102 if normal server did not do it and did not find any results.
1104 Affected file silcd/command.c.
1106 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Moved the internal data from SilcClient context into its
1109 own file, not accesible to application. Affected files
1110 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1111 and other files in client library.
1113 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Added doc/examples installation target in Makefile.am.pre.
1118 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1120 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1121 commands the found client entry will be removed from the
1122 cache, after notifying application about the error. Affected
1123 file lib/silcclient/command_reply.c.
1125 * Changed the /MSG to check for exact nickname user gave, and
1126 not let `nick' match `nick@host' if it is only one found. Now,
1127 user must type the exact nickname (like nick@host2) even if
1128 there are no more than one same nicks found. This is to avoid
1129 a possibility of sending nickname to wrong nickname since
1130 `nick' could match `nick@host'. Affected file is
1131 irssi/src/core/silc-servers.c.
1133 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1135 * Do not print "you are now server operator" or similar when
1136 giving /away command. Affected files are
1137 irssi/src/silc/core/client_ops.c, silc-servers.h.
1139 * Made the silc_server_command_pending_error_check to send
1140 the same command reply payload it received back to the
1141 original sender of the command. This way all arguments
1142 that was received by the server will be received by the
1143 client too. Affected file silcd/command.c.
1145 * Added the silc_idcache_add to return the created cache entry
1146 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1148 * Add global clients to expire if they are not on any channel.
1149 This is because normal server will never know if they signoff
1150 if they are not on any channel. The cache expiry will take
1151 case of these entries. This is done by normal servers only.
1152 The affected files are silcd/command_reply.c,
1153 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1155 * If server receives invalid ID notification for WHOIS or
1156 IDENTIFY and the ID exists in the lists, it is removed.
1157 Affected file silcd/command_reply.c.
1159 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1160 in client then client entry that it matches is searched and
1161 the nickname is printed on the screen for user. Affected
1162 file irssi/src/silc/core/client_ops.c.
1164 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Use cache entry expire time in the LIST command reply to
1167 purge old entries from the cache after the LIST command
1168 reply has been received. This way we don't have non-existent
1169 entries in the cache for too long. Affected file is
1170 silcd/command_reply.c.
1172 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * If we are normal server, and we've not resolved client info
1175 in WHOIS or IDENTIFY from router, and it is global client,
1176 we'll check whether it is on some channel. If it is not
1177 then we cannot be sure about its validity and will resolve it
1178 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1179 file silcd/command.c.
1181 * Search channel by name (if possible) rather than by ID
1182 in IDENTIFY command's command reply. Affected file is
1183 silcd/command_reply.c.
1185 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1188 Updated specs and implemented it. Affected file silcd/command.c,
1189 silcd/packet_send.c and silcd/packet_receive.c.
1191 * Implemented the <founder auth> payload handling in the JOIN
1192 command. If provided all conditions for channel joining
1193 except requirement to provide correct passphrase can be
1194 overrided by the channel founder. Updated the protocol specs.
1195 Affected file silcd/command.c.
1197 Added support for founder auth in JOIN command in client
1198 library. Fixed the parsing of the JOIN command now to support
1199 all options as they should be. The affected file is
1200 lib/silcclient/command.c.
1202 * Optimized the WHOIS and IDENTIFY commands to send the request
1203 to router only if it includes nicknames or other names. If
1204 they include only IDs then check the local cache first before
1205 routing. Affected file is silcd/command.c.
1207 * Added channels topic announcements. Affected file is
1208 silcd/packet_receive.c and silcd/server.c.
1210 * Fixed the silc_server_send_notify_topic_set to really destine
1211 the packet to channel. Affected file silcd/packet_send.c.
1213 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1214 library. Affected file lib/silcclient/client_notify.c.
1216 * Added UMODE announcements. Affected file silcd/server.c.
1218 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1220 * Memory leak fixes in:
1222 lib/silcutil/silcsockconn.c
1223 lib/silcske/silcske.c
1224 lib/silcske/groups.c
1226 lib/silccrypt/silcpkcs.c
1227 lib/silccore/silccommand.c
1228 lib/silccore/silcidcache.c
1233 * ROBOdoc documented the lib/silcske/groups.h file and a
1234 bit changed the interface for better.
1236 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1238 * Update the client entry context in the ID cache after
1239 nick change. Affected file lib/silcclient/command.c.
1240 Fixes the CUMODE command when regaining founder privileges,
1241 and a little WHOIS problem.
1243 * Fixed silc_net_gethostbyname to correctly call the
1244 inet_ntop. Affected file lib/silcutil/silcnet.c.
1246 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1248 * Added IPv6 support checking to the configure.in.pre, added
1249 also --enable-ipv6 option to override the check. Affected
1250 file configure.in.pre.
1252 * The silc_thread_create now calls the start function
1253 directly if threads support is not compiled in. Removes
1254 ugly #ifdef's from generic code. Affected files are
1255 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1257 * Added silc_net_gethostby[name/addr]_async to asynchronously
1258 resolve. Affected files are lib/silcutil/silcnet.[ch].
1260 * Added support for rendering IPv6 based server, client and
1261 channel IDs. Affected file lib/silcutil/silcutil.c.
1263 * Added support for creating IPv6 based server IDs. Affected
1264 file is silcd/serverid.c.
1266 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1268 * Added silc_net_gethostby[addr/name] into the
1269 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1270 routines. Added silc_net_is_ip[4/6]. Affected file is
1271 lib/silcutil/unix/silcunixnet.c. All routines that take
1272 address as argument now supports both IPv4 and IPv6 addresses.
1274 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1276 * Fixed LIST command reply sending in server. Affected file
1279 * Server now sends the kicker's client ID in the KICK notify
1280 to the kicked client. Affected file silcd/command.c.
1282 * The client library now parses the kickers client ID and
1283 UI displays it. Affected files lib/silcclient/client_notify.c
1284 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1286 * Made all payload parsing function prototypes consistent.
1287 They all take now const unsigned char * and uint32 pair as
1288 the payload data instead of SilcBuffer. Changes all around
1289 the source tree. Other unsigned char* -> const unsigned char*
1290 changes around the tree as well.
1292 * Optimized SFTP client and server packet sending not to
1293 allocate new buffer for each packet but to recycle the
1294 first allocated buffer. Affected files are
1295 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1297 * Optimized the SFTP client to use SilcList instead of
1298 SilcDList for requests, because it is faster. Affected file
1299 is lib/silcsftp/sftp_client.c.
1301 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1302 into lib/silccore/silcid.[ch].
1304 Renamed silcpayload.[ch] into silcargument.[ch].
1306 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * If client entry is deleted with active key agreement
1309 session, abort the session.
1311 The silc_client_abort_key_agreement now calls the completion
1312 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1314 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1317 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Don't use __restrict in older GCC's. Affected file is
1320 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1322 * silc_net_localhost now attempts to reverse lookup the
1323 IP/hostname. Affected file lib/silcutil/silcnet.c.
1325 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1326 command. It can be used to gain founder privileges at
1327 the same time when joining the channel.
1329 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1330 kicker's client ID as well. Updated protocol specs.
1332 Defined that the server must send SILC_COMMAND_IDENTIFY
1333 command reply with error status to client who sent
1334 private message with invalid client ID.
1336 Updated the protocol specification.
1338 * Added silc_server_send_command_reply to send any
1339 command reply. Affected file silcd/packet_send.[ch].
1341 * Added silc_id_payload_encode_data to encode ID payload
1342 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1344 * The server now send IDENTIFY command reply with error
1345 status if client ID in private message is invalid. Affected
1346 file silcd/packet_receive.c.
1348 * Save the server key file with server's IP address in
1349 the filename instead of hostname. The affected file is
1350 irssi/src/silc/core/client_ops.c.
1352 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1357 * Added libtool support for compiling shared objects in
1358 lib/silcsim. Affected file configure.in.pre and
1359 lib/silcsim/Makefile.am. Original patch by cras.
1361 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Pid file configuration, and server's config file fixes
1364 patch by toma. Updated CREDITS file.
1366 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Fixed silc_client_channel_message to not try to decrypt
1369 the message twice if it resolved the destination client
1370 information. This could cause of dropping one channel
1371 message. Affected file lib/silcclient/client_channel.c.
1373 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1376 lib/silcclient/client.c. This function is used when the SILC
1377 Client is run under some other scheduler, or event loop or
1378 main loop. On GUI applications, for example this may be
1379 desired to used to run the client under the GUI application's
1380 main loop. Typically the GUI application would register an
1381 idle task that calls this function multiple times in a second
1382 to quickly process the SILC specific data.
1384 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1386 * Fixed silc_server_drop() for dropping the supplementary
1387 groups as well, this could cause a security hole on some
1390 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1395 * Write PID file after dropping privileges. Added -F option
1396 to run server on foreground. A patch by debolaz.
1397 Affected files silcd/server.c, silcd/silcd.c.
1399 * Fixed MOTD to return the MOTD file server name. Affected
1400 file silcd/command.c.
1402 * Added INFO command reply handling to the Irssi SILC Client.
1403 Affected file irssi/src/silc/core/client_ops.c.
1405 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Fixed the silc_idcache_list_* routines to really support
1408 the dynamic list. Fixes a crash. Affected file is
1409 lib/silccore/silcidcache.c.
1411 * Fixed the LIST command reply to really call LIST command's
1412 pending callbacks. Affected file silcd/command_reply.c.
1414 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Update conn->local_entry->nickname after giving NICK
1417 command. Affected file lib/silcclient/command.c.
1419 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1421 * Added the [pid] option to the silcd configuration file
1423 Affected files: serverconfig.[ch] and silcd.c
1425 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Save fingerprint in WHOIS command reply in server.
1428 Affected file silcd/command_reply.c.
1430 * Fixed NICK commands pending callback registration.
1431 Affected file lib/silcclient/command.c.
1433 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Use ++server->cmd_ident when sending commands in server,
1436 instead of random number. Affected file silcd/command.c.
1438 * Fixed GETKEY command reply to call actually GETKEY pending
1439 command callbacks. Affected file silcd/command_reply.c.
1441 * A bit stricter check for nicknames. Check for same nickname
1442 in NICK command also. Affected file silcd/command.c.
1444 * Do not call INFO command everytime client ID changes, only
1445 during first connecting. Affected file lib/silcclient/client.c.
1447 * Set the new nickname only after successful command reply for
1448 NICK command is returned by server. Affected file
1449 lib/silcclient/command.c.
1451 * Remove nicknames from nicklist during server_signoff notify.
1452 Should fix /NAMES bit more. The affected file is
1453 irssi/src/silc/core/silc-channels.c.
1455 * Added `fingerprint' field to the SilcIDListData in the
1456 silcd/idlist.h to hold the fingerprint of the client's
1459 Send the fingerprint of the client's public key in WHOIS
1462 Affected files silcd/command.c, and silcd/idlist.[ch].
1464 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1465 create fingerprint from given data.
1467 * Show the fingerprint of the client's public key in WHOIS.
1468 Affected files irssi/src/module-formats.[ch] and
1469 irssi/src/silc/core/client_ops.c.
1471 * Format the multiple same nicknames also during JOIN and
1472 NICK_CHANGE notifys. Affected file is
1473 lib/silcclient/client_notify.c.
1475 * Do not print error on screen for invalid private message
1476 payload since it can come if someone is sending private
1477 messages with wrong key. Affected file
1478 lib/silccore/silcprivate.c.
1480 * Fixed multiple concurrent /PING crash. Affected file
1481 lib/silcclient/command.c.
1483 * Changed the wrong ID encoding. All IP addresses must be
1484 in MSB first order in encoded format. They were encoded
1485 wrong and was in LSB format. Affected files are
1486 silcd/serverid.c, lib/silcutil/silcutil.c.
1488 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1490 * Call the `connect' client operation through the scheduler
1491 in case of error. Affected file lib/silcclient/client.c.
1493 * Call the `failure' client operation even if the error
1494 occurred locally during a protocol. Affected file is
1495 lib/silcclient/protocol.c.
1497 * Added support of sending LIST command to router from normal
1498 server. This way normal server can get list of all channels
1499 in the network too. Fixed the channel list sending in the
1500 server too. Affected files are silcd/command.c, and
1501 silcd/command_reply.[ch].
1503 * Added silc_server_update_channels_by_server and
1504 silc_server_remove_channels_by_server. They are used during
1505 disconnection of primary router and in backup router protocol.
1506 Affected file silcd/server_util.[ch], silcd/server.c and
1507 silcd/server_backup.c.
1509 * Fixed channel adding to global list in IDENTIFY command
1510 reply in server. Affected file silcd/command_reply.c.
1512 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * If the incoming packet type is REKEY or REKEY_DONE process
1515 that packet always synchronously. Fixes yet another MAC
1516 failed error on slow (dialup) connections. Affected file
1517 lib/silcclient/client.c and silcd/server.c.
1519 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * Call check_version SKE callback for initiator too. Affected
1522 file lib/silcske/silcske.c.
1524 * Implemented fix for security hole found in the SKE that was
1525 fixed in the specification few days back; the initiator's
1526 public key is now added to the HASH value computation.
1527 Added backwards support for the old way of doing it too, for
1528 old clients and old servers. Affected file is
1529 lib/silcske/silcske.c.
1531 * Enabled mutual authentication by default in SKE. If initiator
1532 is not providing mutual authentication the responder will
1533 force it. This will provide the proof of posession of the
1534 private key for responder. The affected files are
1535 lib/silcclient/protocol.c and silcd/protocol.c.
1537 * Do not cache anymore the server's public key during SKE.
1538 We do mutual authentication so the proof of posession of
1539 private key is done, and if the server is authenticated in
1540 conn auth protocol with public key we must have the public
1541 key already. Affected file silcd/protocol.c.
1543 * Added new global debug variable: silc_debug_hexdump. If
1544 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1545 file lib/silcutil/silclog.[ch].
1547 * Fixed compilation warning due to char * -> const char *.
1548 Affected files lib/silcutil/silcnet.h, and
1549 lib/silccore/silcauth.[ch].
1551 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed CMODE command when new channel key was created. If
1554 the creation failed the old key was removed. Next time giving
1555 same command would crash the server since the old key was
1556 freed already. Affected file silcd/command.c.
1558 * Fixed the silc_server_announce_get_channels to not crash
1559 on reconnect. Affected file silcd/server.c.
1561 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Added silc_log_set_debug_string function to set a regex
1564 string to match for debug output. Only the function names,
1565 or filenames matching the given debug string is actually
1566 printed. This way it is possible to filter out those debug
1567 strings that user is not interested in.
1569 Fixed a bug in silc_string_regexify.
1571 Affected files lib/silcutil/silclog.[ch], and
1572 lib/silcutil/unix/silcunixutil.c.
1574 * Changed the -d options in both server and Irssi SILC client
1575 to take the debug string as argument. Affected files
1576 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1578 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Added silc_hash_babbleprint to create a Bubble Babble
1581 Encoded fingerprint. The encoding is developed by Antti
1582 Huima (draft-huima-babble-01.txt), and it creates human
1583 readable strings out of binary data. Affected file
1584 lib/silccrypt/silchash.[ch].
1586 * Print the babble print now in addition of fingerprint as well
1587 in Irssi SILC client. Affected files are
1588 irssi/src/fe-common/silc/module-formats.[ch],
1589 irssi/src/fe-common/silc/core/client_ops.c.
1591 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Fixed a security problem found in SKE. The initiator's
1594 public key too is now added to the HASH hash value creation
1595 which is signed by the responder to create the SIGN value.
1596 This will prevent anyone in the middle to lie to the responder
1597 about the initiator's public key. If this is done now, the
1598 man in the middle will get caught. Updated the protocol
1601 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Better installation directory handling. Configure module
1604 paths and other paths automatically to example_silc* files
1605 in doc/. A patch by toma.
1607 * Fixed compiler warning from MPI library, and from SILC RNG.
1610 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1611 It can be configured with ./configure. A patch by toma.
1613 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Find correct make to use in prepare-clean. A patch by
1616 toma. Affected file prepare-clean.
1618 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1620 * Added irssi variables use_auto_addr, auto_bind_ip,
1621 auto_bind_port and auto_public_ip.
1623 * Changed the interface for silc_client_send_key_agreement

1637 * Added silc_pkcs_public_key_compare to compare two
1638 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1640 * Check that the client who set the founder mode on the
1641 channel is the same client that is giving the founder
1642 mode to itself. It is done by comparing the saved public
1643 key (it is saved even in the authentication is passphrase).

1652 client library. Affected file lib/silcclient/client.c.
1654 * Fixed the silc_client_packet_parse to not to increase
1655 the packet sequence number if the conn->sock and the
1656 current socket connection is not same. This can happen
1657 for example during key agreement when the conn includes
1658 multiple socket connections (listeners). Affected file
1659 lib/silcclient/client.c.
1661 * The sender of the file transfer request now provides also
1662 the pointer (listener) for the key exchange protocol. If
1663 the listener cannot be created then it sends empty key
1664 agreement and lets the receiver provide the listener.
1666 Added `local_ip' and `local_port' arguments to the
1667 silc_client_file_send. If they are provided they are used,
1668 if not then it will attempt to find local IP address, if
1669 not found or bind fails then the remote client will provide
1672 Affected files are lib/silcclient/client_ftp.c and
1673 lib/silcclient/silcapi.h.
1675 * Extended the FILE SEND command to support defining the
1676 local IP and port for key exchange listener. They are

1682 of the client's public key (if the proof of posession of the
1683 corresponding private key is verified by the server).
1684 Updated to the protocol specification.
1686 * Added support of receiving the client's public key's
1687 fingerprint in command reply in client library. Affected
1688 file is lib/silcclient/command_reply.c, and
1689 lib/silcclient/idlist.[ch].

1748 preserve the WHOWAS info for the client. Affected file
1749 silcd/server_util.c.
1751 * Fixed SERVER_SIGNOFF notify handling in the server. The
1752 server is now able to process incoming SERVER_SIGNOFF notify
1753 for a server that it doesn't even know about. It will remove
1754 the clients provided in the notify. Affected file
1755 silcd/packet_receive.c.
1757 * Check for partial packet in data queue after every packet that
1758 was found from the queue. Return and wait for more data if
1759 there is partial data in queue. Affected file is

1781 * Added silc_rng_global_get_byte_fast to get not-so-secure
1782 random data as fast as possible. Random data is read from
1783 /dev/urandom if available and from the SILC RNG if not
1784 available. It is used in padding generation. Affected file
1785 lib/silccrypt/silcrng.[ch].
1787 * All packets in client library are now processed synchronously.
1788 Optimized packet processing a lot. Affected file
1789 lib/silcclient/client.c.

1800 * Assure that silc_client_notify_by_server_resolve does not
1801 resolve the client information multiple times. If it cannot
1802 be found by the first it cannot be found at all. Affected
1803 file lib/silcclient/client_notify.c.
1805 * Fixed WHOWAS command reply calling. Affected file
1806 lib/silcclient/command_reply.c.
1808 * Removed all references to silc_idlist_get_client from the
1809 Irssi SILC client since that call is internal call used by
1810 the library. The Irssi SILC client will use now client
1811 retrieval functions found in silcapi.h.
1813 * Fixed a bug in resolving nickname info before sending
1814 private message. It used freed memory. Affected file
1815 irssi/src/silc/core/silc-servers.c.

1837 Affected file lib/silcutil/silcnet.[ch].
1839 * If key exchange or rekey protocol is active for a connection
1840 parse all packets syncronously since there might be packets
1841 in packet queue that we are not able to process without first
1842 processing packets before them. Affected file silcd/server,
1843 lib/silcclient/client.c.
1845 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1846 whether library should continue processing the packet.
1847 Affected file lib/silccore/silcpacket.h.

1920 * Call the silc_server_udpate_servers_by_server in the
1921 primary router that comes back online in the backup resuming
1922 protocol. Otherwise it routes packets wrong. Affected file
1923 silcd/server_util.[ch], silcd/server_backup.c.
1925 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1927 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1928 lib/silcutil/silcbuffmt.[ch].

1933 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1934 length for maximum padding up to 128 bytes). Affected
1935 file lib/silccore/silcpacket.h.
1937 * Removed all backwards support for old 0.5.x MAC thingies.
1938 The SILC packet header change makes it impossible to be
1939 backwards compatible.
1941 * Send the ENDING packet with timeout in the backup resuming
1942 protocol. This is to assure that all routers has connected
1943 to the primary router. Affected file silcd/server_backup.c.
1945 * Changed the RNG to take the first IV from random data. It
1946 used to take it from zero actually. Changed the RNG also
1947 to use /dev/urandom during session. /dev/random is used
1948 in initialization. Affected file lib/silccrypt/silcrng.[ch].

1953 (the packet length) encrypted. Affected files aroung the
1954 code tree, lib/silccore/silcpacket.[ch]. Removed the
1955 SilcPacketCheckDecrypt callback. It is not needed anymore
1956 since the silc_packet_receive_process will determine now
1957 whether the packet is normal or special.

1970 * Allow backup router to announce servers. All servers
1971 announced by backup router are added to the global list
1972 automatically. Update hte server's socket to our primary
1973 router also when backup router announces a server.
1974 Affected file silcd/packet_receive.c.
1976 * Do not update the client->router in the function
1977 silc_server_udpate_clients_by_server if the client is on
1978 global list. We might fail to find any specific server
1979 for locally connected clients and local cell clients. They
1980 should still use the `from' and not `to' as client->router.
1981 This fixes backup router resuming protocol. Affected file
1982 silcd/server_util.c.
1984 * Decrease channel statistics count only if the channel
1985 deletion worked. Affected files are silcd/server.c and
1986 silcd/server_util.c.
1988 * Added silc_server_update_servers_by_server to update origin
1989 of all server entries. Used during backup router protocol.

2006 to the router it came from. Affected file is
2007 silcd/packet_send.c. Fixed memory leak too.
2009 * Announce informations for incoming router connection, but
2010 only after checking if it is replaced by backup router.
2011 Affected file silcd/packet_receive.c.

2025 Affected file silcd/packet_send.c.
2027 * Changed the SFTP Filesystem interface. Changed the
2028 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2029 the filesystem operation function. The SilcSFTPFilesystem
2030 is now a context that is allocated by all filesystem allocation
2031 functions and it already includes the operations structure
2032 and filesystem specific context. It is given as argument
2033 now to the silc_sftp_server_start. This made the interface
2034 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2035 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2037 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2039 * Changed the backup router adding and getting interfaces
2040 in the server. The router that will be replaced by the

2149 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2151 * Fixed channel user mode saving in client library. Affected
2152 file lib/silcclient/command[_reply].c.
2154 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2156 * Defined the file transfer to the SILC Protocol. Added
2157 new packet type SILC_PACKET_FTP and defined File Transfer
2158 Payload. The mandatory file transfer protocol is SFTP
2159 (SSH File Transfer Protocol). Affected file in addition
2160 of the internet draft is lib/silccore/silcpacket.h.
2162 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2163 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2164 is used as part of backup router protocol when the primary
2165 router of the cell is back online and wishes to resume
2166 the position as primary router.
2168 * Redefined the MAC generation keys in the protocol. The
2169 same key is not used anymore in both direction. Both
2170 direction will now use different keys for sending and
2171 receiving. This fixes a potential security flaw. This
2172 change causes incompatibilities in the protocol.
2174 * Redefined also the MAC computation from the packet.
2175 An packet sequence number is now added to the MAC
2176 computation. This prevents possible replay attacks against
2177 the protocol. This change too causes incompatibilities
2180 Added `sequence' field to the SilcPacketContext to hold
2181 the current sequence number for the packet.
2183 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2185 * Added `created' field to the SilcIDListData in the file
2186 silcd/idlist.h to indicate the time when the entry was
2189 * Added `created' field to the SilcChannelEntry too. Affected
2190 file silcd/idlist.h.
2192 * Added `creation_time' aguments to all the announcement functions
2193 in the server. If it is provided then only the entries that
2194 was created after the provided time frame are actually
2195 announced. Affected file silcd/server.[ch].
2197 * The protocol says that the Channel ID's IP address must be
2198 based on the router's IP address. Added check for this in
2199 the silc_server_new_channel when processing incoming New Channel
2200 Payload. Affected file silcd/packet_receive.c.
2202 * Print out the correct version with --version in SILC client.
2203 Affected file irssi/src/silc/core/silc-core.c.
2205 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Fixed WHOWAS command to check for completnes of the client
2208 entry always, not just when the command is coming from client.
2209 Affected file silcd/command.c.
2211 * Added new function silc_server_packet_queue_purge to purge the
2212 outgoing data queue to the network. After the function returns
2213 it is guaranteed that the outgoing packet queue is empty.
2214 Affected file silcd/packet_send.[ch].
2216 * Purge the outgoing packet queue in the rekey protocol's final
2217 callback to assure that all rekey packets go to the network
2218 before quitting the protocol. Affected file silcd/server.c.
2220 * Added silc_client_packet_queue_parse as similar function as
2221 in server to the client library. The affected file is
2222 lib/silcclient/client.c.
2224 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Splitted silcd/server.c and created silcd/server_util.[ch]
2227 for utility functions.
2229 * Added new socket flag SILC_SF_DISABLED to indicate that the
2230 connection is open but nothing can be sent to or received from
2231 the connection. Affected file lib/silcutil/silsockconn.[ch].
2232 The checking for disabled socket is checked in the low level
2233 silc_socket_write and silc_socket_read functions.
2235 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Allow only nicknames and channel names that fits into the
2238 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2240 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * When processing JOIN command reply in server check that if
2243 the channel exists in our global list we'll move it the local
2244 list. Affected file silcd/command_reply.c.
2246 * Fixed the check whether client is joined on the channel already
2247 in JOIN command. Affected file lib/silcclient/command.c.
2249 * Fixed the JOIN command reply to check whether the channel
2250 already exists. Affected file lib/silcclient/command_reply.c.
2252 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2254 * Added silc_ske_status_string to map the SKE error numbers
2255 to readable strings. The affected files are
2256 lib/silcske/silcske[_status].[ch].
2258 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Do not show the private channels on the WHOIS channel list
2261 as it is not allowed by the protocol. The affected file is
2264 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Assure that the packet length digged from the actual packet
2267 is something sensible in the silc_packet_decrypt_rest_special
2268 in lib/silccrypt/silcpacket.c.
2270 * Free and NULL the allocated pointer in silc_hmac_alloc if
2271 the HMAC allocation fails. The affected file is
2272 lib/silccrypt/silchmac.c.
2274 * Print the selected security properties to the log files in
2275 the server. Affected file silcd/protocol.c.
2277 * Add SKE's reference counter even if calling the completion
2278 callback manually. Otherwise it goes negative, although it
2279 does not cause any problems. The affected file is
2280 lib/silcske/silcske.c.
2282 * Remove the client entry with short timeout after giving the
2283 KILL command. Affected file lib/silcclient/command.c.
2285 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2286 case all found clients are already disconnected (WHOWAS would
2287 found them) in the server. Affected file silcd/command.c.
2289 * Update the last_receive (time of last data received) to be
2290 updated only when received private or channel message so that
2291 the idle time showed in WHOIS makes more sense.
2293 * Added boolean field `valid' in to the SilcClientEntry in the
2294 client library to indicate whether the entry is valid or not.
2295 This fixes the nickname change bug on channel when changing
2296 the nickname to be same than the old (like nick to Nick) the
2297 nickname formatter doesn't set the new nick anymore to Nick@host.
2298 Affected file lib/silcclient/idlist.[ch].
2300 * Now actually fixed the nickname changing on disconnection.
2301 Added new function silc_change_nick to the Irssi SILC Client.
2302 Affected file irssi/src/silc/core/client_ops.c,
2303 irssi/src/silc/core/silc-nicklist.[ch].
2305 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Check that the public key exists in the GETKEY command before
2308 trying to encode it. Affected file silcd/command.c.
2310 * Print some notifications on received public keys with GETKEY
2311 command in the Irssi SILC Client. Affected files are
2312 irssi/src/fe-common/silc/module-formats.[ch],
2313 irssi/src/silc/core/client_ops.c.
2315 * Use IDENTIFY command to resolve the server information in the
2316 GETKEY command instead of INFO command. Affected file
2317 lib/silcclient/command.c.
2319 * All command reply functions in the client library now calls
2320 the pending command reply callbacks even if an error has
2321 occurred. The server has done this a long time and now it was
2322 time to move the client library to this as well. Now all
2323 errors can be delivered back to the pending command reply
2324 callbacks if necessary. Affected files are
2325 lib/silcclient/command[_reply].[ch].
2327 * Change the nickname on disconnection back to the username
2328 because in reconnect the server will enforce it to it anyway.
2329 Affected file irssi/src/silc/core/silc-servers.c.
2331 * Fixed a config file parsing bug in the Irssi SILC client.
2332 Affected file irssi/src/silc/core/clientconfig.c.
2334 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * When printing the channel mode on JOIN, verify that the
2337 channel key and channel's HMAC are valid. Affected file
2338 irssi/src/silc/core/client_ops.c.
2340 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2343 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2344 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2346 * Removed channel key rekey task deleting from the function
2347 silc_server_save_channel_key. Affected file silcd/server.c.
2348 Added explicit timeout task context instead that is used to
2349 delete the task if we are registering a new task before the
2350 new task has elapsed.
2352 * When channel key rekey occurs the client library now saves
2353 the old channel key for a short period of time (10 seconds) and
2354 is able to use it in case some is still sending channel
2355 messages encrypted with the old key after the rekey. Affected
2356 file lib/silcclient/[idlist.h|client_channel.c].
2358 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Added check to the silc_server_new_id_real to not accept
2361 new ID if it is the sender's own ID. Affected file is
2362 silcd/packet_receive.c.
2364 * Assure that we do not announce ourself or the one we've
2365 sending our announcements when we're router and are announcing
2366 servers to our primary router. Affected file silcd/server.c.
2368 * Fixed silc_server_command_identify_check_client to assemble
2369 correct WHOIS packet. It send corrupted WHOIS packet and
2370 caused problem with router to router connections. Affected
2371 file silcd/command.c.
2373 Fixed also silc_server_command_whois_check the same way
2374 as for the IDENTIFY command.
2376 * Added new SilcIDListStatus to the server in the SilcIDListData
2377 structure. The status now includes the current status of
2378 the entry (like registered, resolved etc.). Affected file
2379 silcd/idlist.[ch]. Defined a bunch of different status types
2380 as well. This replaced the old boolean registered field as well.
2382 Added resolve_cmd_ident field to the SilcClientEntry structure
2383 too so that if the entry is for example being resolved so
2384 another command may attach to the same pending command reply
2385 without requiring to resolve the same entry again. This concept
2386 should optimize the WHOIS and the IDENTIFY resolving under
2387 heavy load by taking away unnecessary resolving for entries
2388 that are being resolved already.
2390 Added support for adding multiple pending commands for one
2391 command idenfier. Affected file silcd/command[_reply].[ch].
2393 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2394 before deleting the data. Otherwise the hash table will have
2395 freed data in comparison functions. Affected file is
2396 silcd/command_reply.c.
2398 * Fixed silc_idlist_replace_client_id to add the new entry to
2399 the cache with NULL nickname. Otherwise there will be invalid
2400 memory as the nickname after the nickname is freed. Affected
2401 file silcd/packet_receive.c.
2403 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2404 saved into wrong slots because the previous number of entries
2405 was not taken into account. Affected file silcd/idlist.c.
2406 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2408 * If we are router and we receive JOIN notify to a channel that
2409 does not have any users then notified client is marked as the
2410 channel founder, as it is it. The affected file is
2411 silcd/packet_receive.c
2413 * Added to the extended hash table API's table_del_*ext functions
2414 the destructor as argument too, so that the caller can decide
2415 which destructor to use or whether to use destructor at all.
2416 Affected file lib/silcutil/silchashtable.[ch].
2418 * Fixed ID Cache purging. It actually deleted the entries from
2419 the hash table after the data was freed. The hash table ended
2420 up comparing freed memory. The affected file is
2421 lib/silccore/silcidcache.c.
2423 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Fixed Irssi SILC client's KILL command's HELP syntax.
2427 * The USERS command now resolves the detailed user information
2428 if the userinfo field is missing. Affected file is
2429 lib/silcclient/command_reply.c.
2431 * Do not print error in silc_file_read if the read file does
2432 not exist. Just silently return NULL. Affected file is
2433 lib/silcutil/silcutil.c.
2435 * Fixed the silc_log_output to not wine about NULL filename
2436 and to not create some bogus " " filename. Affected file is
2437 lib/silcutil/silclog.c.
2439 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Fixed various printing bugs on the user interface in the
2442 Irssi SILC Client. Minor changes that were forgotten from
2445 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * Fixed the configure.in.pre and the compilation and distribution
2448 environment to support the new autoconf 2.52. That version is
2449 now required to compile the CVS trunk.
2451 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2454 to generally parse user@fqdn format strings. Affected file
2455 lib/silcutil/silcutil.c.
2457 * Added nickname_format and nickname_force_format fields to the
2458 SilcClientParams structure. The first one defines the format
2459 for the nicknames that the library will enforce if the receives
2460 multiple same nicknames. The second one is boolean value and
2461 can be used to force the library to always enforce the format
2462 to the nicknames regardles whether there are multiple nicknames
2463 or not. This configurable formatting was employed to flexibly
2464 support accessing multiple nicknames from the user interface.
2465 The userinterface can now set the nicknames to what ever format
2466 they prefer. Affected file lib/silcclient/silcapi.h.
2468 Added function silc_client_nickname_format to the file
2469 lib/silcclient/idlist.c. It performs the nickname formatting.
2471 Added new field `hostname´ to the SilcClientEntry context.
2472 It holds the hostname of the client. Affected file is
2473 lib/silcclient/idlist.h.
2475 * Irssi SILC Client sets the nicknames in nick@hostn format.
2476 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2477 irssi/src/silc/core/silc-core.c.
2479 The WHOIS printing now also shows both the real nickname and
2480 the formatted nickname so that user knows how to access the
2481 user if there are multiple same nicknames cached. Affected
2482 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2483 printing formatting too to take the hostname now as a separate
2484 argument. The Affected file is
2485 irssi/src/fe-common/silc/modules-formats.[ch].
2487 * Changed the silc_client_get_clients_local to accept the formatted
2488 nickname as argument. It accepts the real nickname too but the
2489 formatted nickname can be used to find the true entry from
2490 multiple entries. Affected file lib/silcclient/silcapi.h and
2491 lib/silcclient/idlist.c.
2493 * Added nickname_format_parse field to the SilcClientParams.
2494 It is a callback function provided by the application to parse
2495 the nickname out of the formatted nickname string. The library
2496 calls it to get the nickname from the formatted string. Since
2497 the application generally knows better the format of the nickname
2498 string it parses it instead of the library, even though library
2499 encodes the formatted string. If the callback function is not
2500 provided then the library will use the string as is. The
2501 affected file is lib/silcclient/silcapi.h.
2503 * All the nickname strings passed to the client library in
2504 commands are now expected to be formatted nickname strings.
2505 If the command does not support the formatted nickname string
2506 it will assume that the sent string is the actual nickname.
2507 Affected file lib/silcclient/command.c.
2509 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * Added public key authentication support to OPER and SILCOPER
2512 commands in the client library. Affected file is
2513 lib/silcclient/command.c.
2515 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Changed the get_auth_methdod client operation to be asynchronous.
2518 It can be async if the application resolves the authentication
2519 method from the server during the negotiation. Added new
2520 SilcGetAuthMeth completion callback that the application will
2521 call after resolving the authentication method.
2523 Added function silc_client_request_authentication_method that
2524 the application can use to resolve the authentication method
2525 from the server. Added also SilcConnectionAuthRequest callback
2526 that the library will call after the server has replied. The
2527 application can call this function if it does not know the
2528 current authentication method.
2530 Affected files are lib/silcclient/client.c and
2531 lib/silcclient/silcapi.h.
2533 * The Irssi SILC client now automatically resolves the authentication
2534 method incase any configuration information is not present (and
2535 currently there never is). The affected file is
2536 irssi/src/silc/core/client_ops.c.
2538 * Fixed public key authentication from the client library.
2539 Affected file lib/silcclient/protocol.c. Changed also the
2540 protocol specification about the public key authentication in
2541 the connection authentication protocol. The actual data to be
2542 signed is now computed with a hash function before signing.
2544 * Fixed the public key authentication from the server as well.
2545 Affected file silcd/protocol.c.
2547 * Removed the mlock()'s from the memory allocation routines.
2548 Affected file lib/silcutil/silcmemory.c. The ./configure does
2549 not check anymore for the mlock(). Affected file is
2552 * Fixed USERS command in server to allow the execution of the
2553 command for private and secret channels if the client sending
2554 the command is on the channel. Affected file silcd/command.c.
2556 * Fixed silc_client_get_clients_local to return the clients
2557 count correctly. It could return wrong value. Affected file
2558 lib/silcclient/idlist.c.
2560 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2563 types. The assembler optimizations seemed not to like 64-bit
2564 data types. The assmebler optimizations thus are now enabled
2565 also for BSD systems as opposed to only enable them for Linux.
2567 * Do not check for threads at all on BSD systems. Affected
2568 file configure.in.pre.
2570 * Removed -n and -h options from the Irssi SILC Client since
2571 they are not used in silc.
2573 * Fixed the prime generation to assure that the first digit
2574 of the generated random number is not zero since our conversion
2575 routines does not like number strings that starts with zero
2576 digit. If zero digit is seen the random number is regenerated.
2577 This caused some corrupted RSA keys when the zero first digit
2578 was met. Affected file lib/silcmath/silcprimegen.c.
2580 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Fixed WIN32 configuration in the ./configure script.
2583 Fixed to include xti.h on environments that has it.
2584 Patches by Carsten Ilchmann and andrew.
2586 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2588 * Changed the silc_id_create_client_id to be collision
2589 resistant. It is now assured that there cannot be created
2590 two same client ID's. I suspect that some weird bugs in
2591 the server were actually caused by duplicate Client IDs.
2592 Affected file silcd/serverid.[ch]. A router receiving
2593 new ID now also assures and informs the sending server
2594 if the ID caused collision.
2596 * Changed the silc_id_create_channel_id to also assure that
2597 there are no collisions.
2599 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Statement about ignoring the Mutual Authentication flag when
2602 performing rekey with PFS was a bit misleading. It is ignored
2603 if it was set in the initial negotiation, it cannot be even
2604 set in the rekey. Fixed in the ke-auth draft. Started the
2605 new versions of the protocol drafts in the doc/.
2607 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Fixed a bug in silc_client_command_identify_save when saving
2610 new channel information. The channel name was no duplicated
2611 and caused crash on exit. Affected file is
2612 lib/silcclient/command_reply.c.
2614 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed the getkey command handling in the server. Send just
2617 empty OK reply to the sender if the key could not be fetched
2618 (but everything else was ok, like the key just was not available).
2619 Changed the public key parameter to optional in the protocol
2620 specs so that empty OK reply can be sent. Affected file
2623 Added a message to Irssi SILC client to tell to user if the
2624 server did not return a public key.
2626 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2628 * Fixed a channel key regeneration bug. It registered new
2629 timeout tasks exponentially until all system resources were
2630 used. Affected file silcd/server.c.
2632 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Added the SILC Document generator to the scripts/silcdoc.
2635 It can be used to generate the Toolkit Reference Manual out
2636 of the source tree. Internally it will also use the RoboDoc
2637 generator now imported in util/robodoc.
2639 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Added couple of return's in rekey protocol if error orccurred
2642 during the protocol. The execution must be terminated.
2643 Affected file silcd/protocol.c. Also, terminate the protocol
2644 always with timeout.
2646 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2648 * The client's Client ID was created initally from the wrong
2649 nickname (it could have been in format nick@host) in the
2650 silc_server_new_client. Affected file silcd/packet_receive.c
2652 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2654 * Added some SILC_LOG_ERROR's to various error conditions
2655 if client could not be added to ID cache. Affected files
2656 silcd/packet_receive.c and silcd/server.c.
2658 * When client's sock->user_data is freed, NULL also the
2659 client->router and client->connection pointers. Added check
2660 for these pointers being NULL to various places around the
2661 code. Affected file silcd/server.c.
2663 * Added client->data.registered == TRUE checks to various
2664 places around the code to assure that unregistered client's
2665 are not handled when it is not allowed. Affected file
2668 * Added `bool registered' fields to all
2669 silc_idlist_[server|client]_get_* routines to indicate whether
2670 the fetched client needs to be registered or not. Affected
2671 file silcd/idlist.[ch].
2673 * Add your own entry as registered to the ID cache in the
2674 server. Affected file server.c.
2676 * Fixed a bug in silc_server_new_server. The SilcServer was
2677 set as the new server's context instead of SilcServerEntry.
2678 This naturally caused some weird bugs.
2680 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2682 * Do not delete the channel rekey task when adding it
2683 for in silc_server_create_channel_key.
2685 * Changed the silc_server_create_channel_key to return
2686 TRUE or FALSE to indicate the success of the channel key
2689 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Fixed MSVC++ project files and added missing files to

2697 does not have it defined. Affected files are
2698 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2700 * Fixed buffer overflow from Irssi SILC Client. Affected
2701 file irssi/src/fe-common/core/themes.c.
2703 * Fixed double free in client library in the file
2704 lib/silcclient/client.c when disconnecting from server.
2706 * Applied double free patch from cras to Irssi SILC client.
2707 Affected files irssi/src/core/[modules/expandos].c
2709 * Fixed the disconnection handling to Irssi SILC Client.
2710 The application must call silc_client_close_connection
2711 in ops->connect client operation in case of failure of
2712 the connection. Affected file is
2713 irssi/src/silc/core/client_ops.c.
2715 * Do not set sock->protocol to NULL in the function
2716 silc_client_close_connection after executing the protocol's
2717 final callback since the sock might not be valid anymore.
2718 Affected file lib/silcclient/client.c.
2720 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Do not enable SILC_THREADS if the linking with libpthread
2723 did not happen. Affected file configure.in.pre.
2725 * Added notion to protocol specification that server must
2726 verify the sent authentication payload with CMODE when
2727 setting the channel founder key. Implemented it to the
2728 server. Affected file silcd/command.c.
2730 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Added _EXTRA_DIST SILC distribution variable to the
2733 distributions file. It is used to conditionally add extra
2734 files or directories to the specific distribution. Affected
2735 files ./prepare, Makefile.am.pre and distributions.
2737 Removed the `_' from the start of the distribution names.
2740 * Added README.WIN32 for instructions to compile the Toolkit
2743 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Fixed a double free in disconnection in the server. Affected
2746 file is silcd/server.c.
2748 * Fixed the lib/silcske/groups.c to work now also with GMP
2749 MP library. The string conversion did not work when using
2750 specific base and the base is indicated in the string as well.
2752 * Created win32/ directory which now includes MSVC++ specific
2753 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2754 It will appear only in the toolkit distribution
2756 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Changed the key material distribution function in case when
2759 the hash output is too short. The data is now concatenated
2760 a bit differently than it used to. Made the change to the
2761 SKE protocol specification.
2763 * Added better GMP detection to configure.in.pre. A patch
2766 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Fixed a minor bug in SKE that might cause some problem on
2769 some platforms. Affected file lib/silcske/silcske.c.
2771 * Added the cookie checking for initiator in the SKE. It checks
2772 that the responder returns the sent cookie unmodified. The
2773 affected file is lib/silcske/silcske.c. Added new SKE
2774 error type INVALID_COOKIE that can be sent during the
2775 negotiation. Fixed some memory leaks as well.
2777 * Added the "invalid cookie" error message to Irssi SILC client's
2780 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Added `task_max' field to the SilcClientParams to indicate
2783 the maximum tasks the scheduler can handle. If set to zero,
2784 default values are used. Affected file lib/silcclient/silcapi.h.
2786 * Fixed memory leaks in silc_client_close_connection. Affected
2787 file lib/silcclient/client.c.
2789 * Added silc_client_del_client_entry to client library to free
2790 all memory of given client entry. Affected file is
2791 lib/silcclient/idlist.[ch].
2793 * Added new functions silc_client_del_channel and
2794 silc_client_del_server to delete channel and server entries.
2795 Affected file lib/silcclient/[silcapi.h/idlist.c].
2797 * Removed silc_client_del_client_by_id from silcapi.h.
2799 * Fixed the INFO command to return the server's own info
2800 correctly when querying by Server ID. Affected file is
2803 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Removed the non-blocking settings in WIN32 code in the
2806 silc_sock_[read/write] and added SleepEx instead. Affected
2807 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2808 of input data is now checked with FIONREAD and ioctlsocket.
2810 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Call silc_schedule_task_del_by_context in the
2813 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2814 Affected file lib/silccore/silcprotocol.c.
2816 * Call silc_protocol_cancel for active protocols in the
2817 silc_server_close_connection if the funtion
2818 silc_server_free_sock_user_data has not been called.
2819 Affected file silcd/server.c.
2821 * Generic tasks cannot be deleted using the del_by_fd
2822 task deleting function since generic tasks does not match
2823 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2825 * Added a notion to SILCOPER help file that the SILCOPER works
2826 only on router server, not on normal server.
2828 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2830 * Added for WIN32 support for the new scheduler as well.
2831 Affected file lib/silcutil/win32/silcwin32schedule.c.
2833 * Fixed the SHA1 implementation to work on various platforms.
2835 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2837 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2838 API. It is part of the scheduler now. Everything else is
2839 as previously but some functions has changed their names.
2840 Checkout the lib/silcutil/silcschedule.h for the interface.
2841 Updated all applications to use the new interface. Affected
2842 files are lib/silcutil/silcschedule.[ch].
2844 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Found a bug in the SKE implementation. The HASH value,
2847 specified by the protocol, was not computed correctly. The
2848 public key of the responder was not added to the computation
2849 even though it is mandatory. Affected file lib/silcske/silcske.c.
2850 This unfortunately causes incompatibilities with older
2851 clients and servers.
2853 * Added WIN32 specific network init and uninit functions:
2854 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2855 the Winsock2. Affected file lib/silcutil/silcnet.h and
2856 lib/silcutil/win32/silcwin32net.c.
2858 * Set the socket always to nonblocking mode on WIN32 after
2859 reading data or writing data. Affected file is
2860 lib/silcutil/win32/silcwin32sockconn.c.
2862 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Fixed various compilation problems under WIN32. Affected
2865 files lib/silcutil/win32/silcwin32thread.c and
2866 lib/silcutil/win32/silcwin32schedule.c.
2868 * Removed all _internal.h #includes from public header
2869 files. Internal headers must never be included from
2872 Removed also the lib/silcske/payload_internal.h file.
2874 * All include files that may be needed (public and some others
2875 included by the public headers) by application developers are
2876 now copied to the ./includes directory. It does not copy any
2877 internal headers. Affected file Makefile.defines.pre and all
2878 Makefile.am's under lib/ and subdirs.
2880 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Do not change the ~/.silc directory's permissions automatically.
2883 Affected file irssi/src/silc/core/clientutil.c.
2885 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Do not cancel the protocol in silc_server_close_connection
2888 it might cause recursion. Now cancelled in the function
2889 silc_server_free_sock_user_data. Affected file silcd/server.c.
2891 * Fixed the silc_server_remove_clients_by_server to regenerate
2892 the channel keys correctly finally. Added also new function
2893 silc_server_remove_clients_channels to actually do it.
2894 Affected file silcd/server.c.
2896 * Fixed the silc_server_new_channel to not crash by giving
2897 wrong router to the new channel. Affected file is
2898 silcd/packet_receive.c.
2900 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2903 which is given as argument to the silc_client_alloc now.
2904 It can be used to configure the client and set various parameters
2905 that affect the function of the client.
2907 * The USERS command in server did not check whether the channel
2908 is private or secret. Affected file silcd/command.c.
2910 * Added new argument to the USERS command in protocol specification.
2911 The USERS command now can take the channel name as argument
2912 as well. Added support for this in client and server and
2913 updated the protocol specs.
2915 * Completed the GETKEY command in client. It can be now used
2916 to fetch also servers public key not only some clients.
2917 Affected files lib/silcclient/command[_reply].c.
2919 * Added silc_client_get_server to return server entry by the
2920 server name. Affected files lib/silcclient/silcapi.h and
2923 * Redefined the IDENTIFY command in protocol specification to be
2924 more generic. It now can be used to query information about
2925 any entity in the SILC Network, including clients, servers and
2926 channels. The query may be based either the entity's name
2927 or the ID. Added support for this in both client and server.
2929 Affected files silcd/command.c and lib/silcclient/command.c
2930 and command_reply.c.
2932 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2933 the _from_client and _from_server functions. Affected file
2936 * Added silc_client_get_channel_by_id_resolve to the file
2937 lib/silcclient/silcapi.h to resolve channel information by
2938 its ID. Added also silc_client_get_channel_by_id that
2939 does not resolve it from the server.
2941 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Added SilcServerEntry context into the client library
2944 to represent one server. The INFO command now allocates
2945 these to save the resolved server info. For now on the
2946 client library will also keep information about servers,
2947 connected and resolved with INFO.
2949 The INFO command now allocates the SilcServerEntry context
2950 and saves the server info there. The COMMAND_REPLY in
2951 the INFO now returns the parameters to application in
2952 same order as defined in the protocol specification.
2954 The entries are cached in the client->server_cache.
2956 * The INFO command is now issued after received the Client ID
2957 from the server. Affected file lib/silcclient/client.c.
2959 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2960 to the application as the mode changer might be server.
2961 It is guaranteed that NULL is not returned anymore to the
2962 application. Affected file lib/silcclient/client_notify.c.
2964 The ID Type is now also passed to the application so that
2965 it can check whether the returned entry is SilcClientEntry
2968 Added new function silc_client_get_server_by_id to return
2969 the server entry by ID. Affected files are the
2970 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2972 * Do not create the channel in the Irssi SILC Client when issuing
2973 the JOIN command but when received the sucessful JOIN command
2974 reply. Otherwise the channel might get created even though we
2975 could not join it. The Affected file is
2976 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2978 * Fixed a channel joining bug in router. The router must also
2979 check the channel modes, invite and ban lists etc. when serving
2980 the JOIN command sent by normal server. Affected file is
2981 silcd/command.c. The router now resolves the client's
2982 information from the server who sent the JOIN command if it
2983 does not know it, and processes the JOIN command only after
2986 * Changed the SilcCommandCb to take new argument; void *context2.
2987 Affected file lib/silccore/silccommand.h
2989 The second argument in the command callbacks in the server now
2990 includes the SilcServerCommandReplyContext if the command was
2991 called as pending command callback from the command reply.
2992 Otherwise it is NULL. When called as pending the status of the
2993 command reply will be checked and if it was erronous the
2994 error will be sent to the original sender of the command.
2995 This way the client always receives the error messages even
2996 though the server was actually the one who received the error
2997 when it resent the command to router, for example. Affected
2998 files silcd/command[_reply].[ch].
3000 * Fixed sending WHOWAS command's error message to client if
3001 the requested client could not be found. It was missing.
3004 * Changed the CMODE and CUMODE commands reply arguments in the
3005 protocol specification. The Channel ID is now sent in both
3006 of the commands to identify the channel. Implemented this
3007 new feature to the client and server. Affected files
3008 lib/silcclient/command_reply.c and silcd/command.c.
3010 * Made better checks for invite and ban lists in the JOIN
3011 command in server. Affected file silcd/command.c.
3013 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * The server now performs the incoming host IP/DNS lookup
3016 using the silc_socket_host_lookup and thus does not block
3017 the server anymore. Affected file silcd/server.c.
3019 * Completed the multi-thread support for SILC Scheduler in
3020 the lib/silcutil/silcschedule.c.
3022 * Fixed the configure.in.pre to detect the pthread correctly
3025 * Fixed a deadlock in silc_task_queue_wakeup in the file
3026 lib/silcutil/silctask.c.
3028 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Added new function silc_schedule_wakeup that is used in
3031 multi-threaded environment to wakeup the main thread's
3032 schduler. It needs to be used when a thread adds a new task
3033 or removes a task from task queues. After waking up, the
3034 scheduler will detect the task queue changes. If threads
3035 support is not compiled in this function has no effect.
3036 Implemented the wakeup mechanism to both Unix and WIN32
3037 systems. Affected files are lib/silcutil/silcschedule.[ch],
3038 lib/silcutil/unix/silcunixschedule.c and the
3039 lib/silcutil/win32/silcwin32schedule.c.
3041 * Added new function silc_task_queue_wakeup to wakeup the
3042 scheduler by the specified task queue. Affected file
3043 lib/silcutil/silctask.[ch].
3045 * The silc_socket_host_lookup_start now wakes up the scheduler
3046 after adding the timeout task. Affected file is
3047 lib/silcutil/silcsockconn.c.
3049 * The silc_socket_host_lookup is synchronous now if the threads
3050 support is not compiled in. However, the callback is still
3051 called asyncronously through the scheduler, anyway. Affected
3052 file lib/silcutil/silcsockconn.c.
3054 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3056 * Added new function silc_socket_host_lookup to perform
3057 asynchronous IP and FQDN lookups for the socket connection.
3058 Affected files lib/silcutil/silcsockconn.[ch].
3060 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3063 that may or may not compile the mutex support in.
3065 Changed the silc_mutex_alloc interface. It allocates the
3066 mutex now to the sent pointer and returns TRUE or FALSE.
3068 Affected file lib/silcutil/silcmutex.h.
3070 * Wrote the SILC Task Queue interface to support multi-threads.
3071 Affected file lib/silcutil/silctask.[ch].
3073 * Wrote the SILC Scheduler to support multi-threads. Affected
3074 file lib/silcutil/silcschedule.c.
3076 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3079 in lib/silcutil/win32/.
3081 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Defined SILC Mutex API and SILC Thread API and implemented
3084 them for Unix. Affected files are
3085 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3086 lib/silcutil/unix/silcunixmutex.c and
3087 lib/silcutil/unix/silcunixthread.c.
3089 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3091 * Fixed the silc_server_remove_clients_by_server's channel
3092 key re-generation. The hash table handling was incorrect
3093 and would not work with many channels. Affected file is
3096 * Fixed some memory leaks around the server code.
3098 * Rewrote the silc_server_get_users_on_channel to support IPv6
3099 based Client ID's. Affected file silcd/server.c.
3101 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3102 specification. However, a separate document must be written
3103 to define the detailed signing procedure and the payload
3104 associated with the flag. Defined the flag to the
3105 lib/silccore/silcchannel.h as well.
3107 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Changed the dynamic tables to static size tables in the
3110 lib/silccrypt/silchmac.c.
3112 * Removed GCC dependencies from the code. A patch by cras.
3114 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Do not show the error "Error receiving packet bla bla"
3117 in server if it really was not an error (-2 means that reading
3118 is pending). Affected file silcd/server.c.
3120 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3122 * Fixed a possible crash in silc_server_remove_clients_by_server
3123 in silcd/server.c. Fixed there also some memory leaks.
3125 * Fixed the silc_idlist_replace_client_id. It could replace
3126 wrong key in the hash table. Affected file silcd/idlist.c.
3128 * Do not check whether there are global users on the channel
3129 if the channel->global_users is FALSE. Affected functions
3130 silc_server_remove_from_one_channel and
3131 silc_server_remove_from_channels in silcd/server.c. Also,
3132 do not check if the removed client is local as we can be
3133 sure that global client was not removed from the channel
3134 and checking for global users is not needed.
3136 * The silc_server_remove_clients_by_server now re-generates
3137 the channel keys correctly for those channels that had
3138 clients removed from them. Affected file silcd/server.c.
3140 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Found the reason of random crashes in the server. We weren't
3143 ignoring the SIGPIPE signal (which can be sent in write())
3144 and it crashed the server. Affected file silcd/silcd.c.
3146 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3148 * Assure that sock->user_data is not NULL in the function
3149 silc_server_packet_send in silcd/packet_send.c.
3151 * Disconnect the remote connection if it could not be added
3152 to any ID lists in the server. The affected file is
3155 * Check in silc_server_packet_send[_real/dest] that the
3156 socket is not disconnecting and ignore the data if it is.
3157 Affected file silcd/packet_send.c.
3159 * Define inline to __inline on native WIN32 compilation.
3160 Affected file includes/silcwin32.h.
3162 * Added some explicit type casts for inline code since MSVC
3163 require them. Affected files lib/silcutil/silcbuffer.h,
3164 lib/trq/silcdlist.h and lib/trq/silclist.h.
3166 * Print warning in log files from now on if the packet
3167 decryption fails. Affected file silcd/server.c.
3169 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Changed the `say' client operation's interface to accept
3172 new `type' argument to indicate the type of the message sent
3173 by the library. The application may filter the library's
3174 messages according the type. The affected file is the
3175 lib/silcclient/silcapi.h.
3177 * Added two new functions to lib/silcclient/silcapi.h:
3178 silc_client_del_client and silc_client_del_client_by_id.
3179 Affected file lib/silcclient/idlist.c.
3181 * Moved the clientincludes.h from includes/ to silc/ and
3182 serverincludes.h from includes/ to silcd/.
3184 * The modes for the CMODE and CUMODE are now passed as
3185 uint32 for application with COMMAND_REPLY. The affected
3186 file is lib/silcclient/command_reply.c.
3188 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * /WHOIS without arguments shows client's own information.
3191 Affected file lib/silcclient/command.c.
3193 * Changed PING to not accept any arguments. The specs
3194 says that client can ping only the connected server so
3195 requiring an argument is not needed. Affected file is
3196 lib/silcclient/command.c.
3198 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Fixed a fatal bug in private message sending and reception
3201 encryption and decryption when using private message keys.
3202 The implementation was incorrect and did not follow the
3203 specification. It causd that some of the message were
3204 lost since it did not use the sending and receiving keys
3205 as the protocol suggests. This has been fixed and will cause
3206 incompatibilities with older clients when sending private
3207 message encrypted with private message keys. Affected files
3208 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3209 and various other in Irssi SILC Client.
3211 Added `responder' boolean argument to the functions
3212 silc_client_add_private_message_key[_ske] to indicate when
3213 the key is added as responder or initiator of the key
3216 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Removed the silc_ske_check_version function and created
3219 a SilcSKECheckVersion callback. Added also a function
3220 silc_ske_set_callbacks that is now used to set all SKE
3221 callbacks. The callback functions are not given to
3222 the SKE functions anymore, but this function is used to
3225 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3227 * Added `silc_version' argument to the silc_client_alloc
3228 to define the version of the application for the library.
3229 The library will use the version string to compare it
3230 against the remote host's (usually a server) version
3231 string. Affected file lib/silcclient/silcapi.h
3233 * Added the KE protocol context to Key Agreement context
3234 in client library so that we can abort the SKE if it
3235 is in process when we get timeout. Affected file is
3236 lib/silcclient/client_keyagr.c.
3238 * Do not resolve the client ID forever if it returns in the
3239 first time that such client does not exist. This was done
3240 for example with private message. Affected file is
3241 lib/silcclient/client_prvmsg.c.
3243 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Do not add regex.h for WIN32. The affected file
3246 includes/silcincludes.h.
3248 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3249 not work yet 100%. It generates the DLL's automatically
3250 when compiling with --with-win32 under cygwin.
3252 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * lib/contrib/regex.c is not compiled on WIN32.
3256 * Added silc_net_get_socket_opt function to the
3257 lib/silcutil/silcnet.h.
3259 * Added includes/silcwin32.h for WIN32 specific includes
3262 * Do not use ptime structure or any of the posix process
3263 functions on WIN32 in lib/silccrypt/silrng.c.
3265 * Added silc_gettimeofday to provide generic function
3266 for struct timeval on all platforms. Added the function
3267 to lib/silcutil/silcutil.h.
3269 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3272 library as they clearly belong there. As a plus side we
3273 can make the actual socket connection routines platform
3276 Added also new generic function silc_socket_read and
3277 silc_socket_write (that used to be silc_packet_[read/write].
3278 The implementation of these are platform specific.
3280 * Added WIN32 specific routines of silc_socket_[read/write]
3281 to lib/silcutil/win32/silcwin32sockconn.c.
3283 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3285 * Added preliminary support for native WIN32 compilation under
3286 cygwin (using the -mno-cygwin option for GCC) to the
3287 ./configure.in.pre. The --with-win32 now prepares the
3288 compilation for native WIN32.
3290 * Rewrote the SILC Scheduler interface in the file
3291 lib/silcutil/silcschedule.h. The scheduler is now context
3292 based and does not have anymore any global static scheduler.
3293 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3294 and created lib/silcutil/win32 directory for WIN32 based
3297 * Added Unix specific network routines to the
3298 lib/silcutil/unix/silcunixnet.c and the old
3299 lib/silcutil/silcnet.c includes now only generic routines.
3301 Added WIN32 specific network routines to the
3302 lib/silcutil/win32/silcwin32net.c.
3304 * Added Unix specific utility functions from the
3305 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3307 * Added WIN32 SILC Scheduler to the file
3308 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3311 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Do not handle JOIN notify in the server if the target client
3314 is not registered (idata->registered == FALSE). The affected
3315 file is silcd/packet_receive.c.
3317 * Update the nickrec->founder in event_cumode in the Irssi SILC
3318 client. Affected file irssi/src/silc/core/silc-channels.c.
3320 * Fixed the CUMODE_CHANGE notify handling in the server when
3321 server and router are announcing their clients on channels.
3322 Now the mode changes are saved and notified correctly. The
3323 affected file is /silcd/packet_receive.c.
3325 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3326 They really did not replace the cache entry in the ID Cache.
3327 Now they do that. Affected file silcd/idlist.c.
3329 * Fixed the KICK notify handling in the Irssi SILC client to
3330 update the channel records so that the kicked client does not
3331 appear to be on the channel. The affected file is
3332 irssi/src/silc/core/silc-channels.c.
3334 * Always update the conn->current_channel when executing command
3335 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3337 * Fixed the KILL notify handling in Irssi SILC client to remove
3338 the killed client on all channels.
3340 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Fixed the silc_parse_command_line to remove extra spaces
3343 from the start and end of the arguments. Affected file is
3344 lib/silcutil/silcutil.c.
3346 * Cancel and free any active protocol in the function
3347 silc_server_close_connection. Affected file silcd/server.c.
3349 * Cancel and free any active protocol in the function
3350 silc_client_close_connction. Affected file is
3351 lib/silcclient/client.c.
3353 * Do not execute the KILL command for clients that are in
3354 history (ie. they are not in the network). Affected file is
3357 * Fixed KILL notify handling, client does not crash anymore.
3358 Affected file irssi/src/silc/core/silc-channels.c.
3360 * Reduced the default packet buffer size from 2048 to 1024 in
3361 lib/silccore/silcpacket.c.
3363 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3364 counter to the SKE context that is incresed when the SKE library
3365 performs async operation outside the library. If the outside
3366 process frees the SKE context and FREED status will be set
3367 and the library will detect after the sync operation that the
3368 libary is freed. The affected files are
3369 lib/silcske/silcske[_status].[ch].
3371 * Resolve the client entry information in the function
3372 silc_client_channel_message to assure that NULL pointer is not
3373 passed as client entry to the application. */
3375 * Fixed the task timeout calculation to assure that there is
3376 never negative timeouts. The affected file is
3377 lib/silcutil/silcschedule.c.
3379 * Fixed the channel user mode notification sending in server.
3380 It was sent point-to-point to the router (or to server by router)
3381 but it needs to be destined to a channel. The routines now
3382 supports sending the channel user mode notifys to the channels
3383 when announcing clients and channels. Affected files are
3384 silcd/server.c and silcd/packet_receive.c.
3386 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3387 It did not actually replace the old channel entry in the cache.
3388 Affected file lib/silcclient/client_notify.c.
3390 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * Fixed a possible crash in silc_packet_send_prepare. It now
3393 assures always that there is enough space in the buffer and
3394 at the tail area of the buffer (for MAC).
3396 Fixed the inbound buffer reallocation in silc_packet_read.
3397 It was old code and did not handle the reallocation correctly.
3400 The affected file is lib/silccore/silcpacket.c.
3402 * Fixed buffer overflow in silc_parse_nickname in the file
3403 lib/silcutil/silcutil.c.
3405 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * make install generates new server keys only if there is not
3410 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3412 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3413 Added check that if the NOREPLY is set then we will not send
3414 the away message. This avoids infinite loop of away messages
3415 if both clients are away. The affected file is
3416 lib/silcclient/client_prvmsg.c.
3418 * Fixed client crash if /NICK was given without arguments.
3419 Affected file lib/silcclient/command.c.
3421 * Server does not send the invite list in INVITE command back
3422 to the client if the list was not altered. Added this notion
3423 to the protocol spec as well. Affected file silcd/command.c.
3425 Fixed possible crash in INVITE command by checking the
3426 value of silc_server_get_client_route command.
3428 * Fixed the INVITE notify type handling. The arguments are now
3429 taken in correct order and client does not crash. The affected
3430 file is irssi/src/silc/core/silc-channels.c.
3432 Removed the "Inviting xxx to channel" message from the
3433 client library away and let the application handle it.
3434 Affected file lib/silcclient/command.c. Added that message
3435 to Irssi SILC client's message formats.
3437 * Fixed CMODE command crash in client. It now checks the
3438 amount of arguments correctly and does not crash. The affected
3439 file is lib/silcclient/command.c.
3441 * Do not create new channel automatically in silc_channels_join
3442 but check whether the channel by that name already exists.
3443 Affected file irssi/silc/core/silc-channels.c.
3445 * Do not send the SERVER_SIGNOFF to router if the disconnected
3446 entity was the router. Affected file silcd/server.c.
3448 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3449 SILC client as it was missing from there.
3451 Added the handling of the KICK notify to the Irssi SILC client
3452 as it was missing. Added "you have been kicked" message to
3453 Irssi SILC client's message modules formats.
3455 Added the handing of the KILL notify to the Irssi SILC client
3456 as it was missing. Added the kill message module formats
3459 The affected file is irssi/src/silc/core/silc-channels.c.
3461 * The router did not save the channel mode the server announced.
3462 Affected file silcd/packet_receive.c.
3464 * Fixed a possible crash in INFO command in server. If the
3465 server did not provide the server info it crashed. Affected
3466 file silcd/command.c.
3468 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Fixed the GETKEY command in the server to check also the
3471 global list. Otherwise the GETKEY would not work correctly
3472 in normal SILC server. Affected file silcd/command.c.
3474 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Fixed GETKEY crash, it crashed if the command did not succseed.
3478 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3481 is now real and not just an macro interface to GMP.
3483 Removed the entire GMP from the source tree and imported new
3484 NSS MPI library instead. Reason for removing GMP is that it is
3485 extremely large and compiles extremely slow. The NSS MPI
3486 is only a few files and compiles in less than 10 seconds.
3487 The speed is also about the same as GMP. The MPI is imported
3488 to lib/silcmath/mpi.
3490 If the system has GMP installed we will still use the GMP.
3491 If it is not then the NSS MPI will be compiled.
3493 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3495 * Merged a long nickname (127 characters long) crash bugfix from
3496 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3498 * Merged a freed memory reference bugfix from Irssi CVS tree.
3499 Affected file irssi/src/core/commands.c.
3501 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added the server's public key sving and verification to the
3504 server when performing the SKE. This was missing and the
3505 remote server's (or router's) public key was accepted without
3506 checking whether we have it previously or trust it at all.
3507 Affected file silcd/protocol.c.
3509 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Check in the silc_server_timeout_remote if protocol is active
3512 and make sure that the protocol's final callback is called so
3513 that all memory if freed. Affected file silcd/server.c.
3515 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * silc_server_whois_send_reply crashed the server if the nickname
3518 was 127 characters long. Affected file silcd/command.c.
3520 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Added sanity check to the silc_server_new_client. If the hostname
3523 is provided inside username then check that the provided hostname
3524 really is the same as the resolved one. If the hostname was not
3525 resolved then check it from the public key. Affected file is
3526 silcd/packet_receive.c.
3528 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3529 if the server disconnected us and the connection is not valid
3530 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3532 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3533 the library to the lib/silcutil/silcutil.[ch].
3535 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Close log file after open. Affected file
3538 lib/silcutil/silclog.c.
3540 * Check whether sock == NULL in silc_client_send_packet and return
3541 if it is. Affected file lib/silcclient/silcclient.c.
3543 * Check rec->entry == NULL in the Irssi SILC Client before
3544 sending the channel message. Affecte file is
3545 irssi/src/silc/core/silc-servers.c.
3547 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Merged a splitted window bugfix from Irssi CVS tree. The
3550 affected file is irssi/src/fe-text/textbuffer-view.c.
3552 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3553 It did not print nickname.
3555 * Improved the distributions system a bit.
3557 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3559 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3560 irssi/src/fe-text/gui-window.c.
3562 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3563 to in-active server. The affected file is
3564 irssi/src/silc/core/client_ops.c.
3566 * Resolve the client in USERS command reply if the entry does
3567 not have username resolved. The affected file is
3568 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3569 command to WHOIS command to really resolve stuff. The USERS
3570 is not used any more in any critical section so WHOIS can
3571 be used even though it might be slower than IDENTIFY.
3573 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3576 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Changed the protocol API a bit more consistent in the
3579 lib/silccore/silcprotocol.[ch].
3581 * Changed the following headers to ROBODoc format:
3583 lib/silccore/silcpayload.h
3584 lib/silccore/silcprotocol.h
3585 lib/silccore/silcsockconn.h
3587 All core library headers are now formatted.
3589 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Fixed a bug in Irssi SILC client; do not show that you are
3592 server/router operator if you really are not. Affected file is
3593 irssi/src/silc/core/client_ops.c.
3595 * Renamed silc_command_free_payload to silc_command_payload_free.
3596 Affected file lib/silccore/silccommand.h
3598 * Added silcmath.h to include the prototoypes of various routines
3599 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3602 * Changed the following headers to ROBODoc format:
3604 lib/silccore/silcchannel.h
3605 lib/silccore/silccommand.h
3606 lib/silccore/silcid.h
3607 lib/silccore/silcidcache.h
3608 lib/silccore/silcmode.h
3609 lib/silccore/silcnotify.h
3610 lib/silccore/silcpacket.h
3611 lib/silcmath/silcmath.h
3613 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Added checking to the server code not to start the server if
3616 ciphers and stuff are not configured properly. Affected files
3617 silcd/serverconfig.[h] and silcd/server.c.
3619 * Changed the layout of the header files of the public interfaces
3620 in the SILC libraries. The new layout supports ROBODoc
3621 documentation tool (and some others) so that it is easy to create
3622 a library reference manual. All the other headers and source
3623 code must still follow the CodingStyle document. Also source
3624 code must not include these ROBODoc stuffs, only the headers.
3625 Furthermore, all public interface headers must now be named
3626 by using `silc' prefix, example: silcapi.h, silccipher.h.
3627 Some files were renamed due to this. All the other headers
3628 must not be used as public interfaces. I will update the
3629 CodingStyle document later. Changed following headers, so far:
3631 lib/silcclient/silcapi.h
3632 lib/silccore/silcauth.h
3633 lib/silccore/silcprivate.h
3634 lib/silccrypt/silcdh.h
3636 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Removed silc_client_packet_send_flush from the client library
3641 as it is not needed. Affected file lib/silcclient/client.[ch].
3643 * Added printing of message of unresolved authentication method
3644 to the Irssi SILC client. Added it to the module formats.
3645 Removed the same message from the client library.
3647 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * Added new distribution feature, DISTLABEL. Every distribution
3650 can define own preprocessor label that can be used in the
3651 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3652 file distributions, acconfig.h.pre and prepare.
3654 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Added Makefile.defines_int to include the actual definitions
3657 for Makefile.defines.in. Tested the new distribution system,
3658 created distributions and tested installation.
3660 * Added AWAY message printing to the Irssi SILC client. Added
3661 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3663 * Added SCONNECT command to call the SILC's CONNECT command.
3664 Cannot use CONNECT directly since Irssi uses that internally.
3665 Affected file irssi/src/silc/core/silc-servers.c.
3667 Added ACTION local command. It is same as ME command but takes
3668 the channel as mandatory argument.
3670 Rewrote some of the Irssi's help files to suite for SILC
3673 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Added Makefile.defines[.in] that should for now on be included
3676 in all Makefile.am file in the source tree. That file includes
3677 all common compilation definitions for SILC source tree.
3679 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Minor changes to the ./prepare script to change the package
3682 name according the distribution name to the configure.in.
3684 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Created new distribution system. Added file `distributions'
3687 that defines all the distributions that can be created out of
3688 the SILC source tree. The ./prepare script now reads that
3689 file to determine how to prepare the distributions. The
3690 first argument to the ./prepare is the name of the distribution
3691 and second is the version of the distribution. If given
3692 without arguments it creates the default (toolkit) distribution
3693 with the default version (defined in ./prepare).
3695 All Makefile.am files that are subject to the distributions
3696 are now named as Makefile.am.pre. These are ./Makefile.am
3697 and lib/Makefile.am. Others may be changed later.
3699 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3701 * Added invite list, ban list, some key management and connection
3702 error message printing to module formats in the Irssi SILC client.
3704 * Added new silc_client_set_away_message to set the away message
3705 that is back to the person who sent private message. The
3706 affected file lib/silcclient/silcapi.h and the
3707 lib/silcclient/client_prvmsg.c.
3709 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Fixed the private message sending in the Irssi SILC client,
3712 added local command KEY to the Irssi SILC client.
3714 Added key management and key agreement message formats to the
3715 irssi/src/fe-common/silc/module-formats.[ch].
3717 Added USERS (alias WHO) printing, server/router operator
3718 indication and LIST command printing to the module formats.
3720 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Fixed channel joining notify handling, cumode notify handling
3723 from Irssi SILC client.
3725 * Added SILC specific module-formats to the Irssi SILC client so
3726 that SILC specific message hilighting, colors etc is possible.
3727 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3729 Added channel mode, channel user mode, actions, notices,
3730 whois and whowas printing to the the module-formats.c.
3732 * Fixed a bug in channel deletion in the server. The channel
3733 is not left to the cache even if the channel founder auth mode
3734 is set when there are no users anymore on the channel. Affected
3735 file silcd/server.c.
3737 * The silc_net_localhost now resolves the entire hostname including
3738 the domain name. Affected file lib/silcutil/silcnet.c.
3740 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Changed the ask_passphrase client operation to be ascynchronous.
3743 It has now a completion callback and a context that the
3744 application must call after it has got the passphrase from
3745 the user. Affected files lib/silcclient/silcapi.h,
3746 lib/silcclient/protocol.c, lib/silcclient/command.c and
3749 Added SilcAskPassphrase callback that the application calls
3750 to deliver the passphrase to the library.
3752 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3753 The public key verification and especially a certificate
3754 verification is asynchronous procedure.
3756 Added new SILC_SKE_STATUS_PENDING status to indicate the
3757 request is pending and a callback will be called to finalize
3760 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3761 indicate that remote end did not send its public key (or
3762 certificate), even though we require it. Added check for this
3763 condition in the SKE. This was a security bug, now fixed.
3765 Defined new SilcSKEVerifyCbCompletion callback that is called
3766 when the verification process is completed.
3768 The affected files lib/silcske/silcske_status.h and
3769 lib/silcske/silcske.[ch].
3771 * Changed the verify_public_key client operation to be async
3772 as well. Defined SilcVerifyPublicKey callback that is used to
3773 indicate the success of the public key verification process.
3775 Changed the server and client to use the new async client
3778 * Changed the Irssi SILC client's internal scheduler to be called
3779 twice as many times as it used to be. As a result the client
3780 should be a bit faster now. Affected file is
3781 irssi/src/silc/core/silc-core.c.
3783 * Added support to Irssi SILC client of asynchronous public key
3784 verification and passphrase inquiry. Affected file is
3785 irssi/src/silc/core/silc-core.c.
3787 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Do not say "You have left channel %s" in client library.
3790 Moved it to the application. Affected files are
3791 lib/silcclient/command.c and silc/client_ops.c.
3793 * Fixed silc_client_get_clients. Command context was not
3794 duplicated and was freed memory in the callback. Affected
3795 file lib/silcclient/idlist.c.
3797 * Do not say "you are now talking..." on JOIN command in the
3798 client library. The appliation must handle it.
3800 * Do not say ".. changed topic to" in command reply in the
3801 client libary. The application must handle it.
3803 * Fixed TOPIC command sending in the client library.
3805 * Fixed a memory leak in silc_client_command_free in the file
3806 lib/silcclient/command.c.
3808 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Imported a modified version of Irssi client to the source tree.
3811 The Irssi will be used to create a new client called
3812 Irssi SILC. Imported to irssi/.
3814 Added silc_core_init_finish function to the Irssi. Affected
3815 file irssi/configure.in.
3817 A lot changes in the Makefile.ams around the irssi tree.
3819 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Do not rehash if the new size is same as the old size of the
3822 hash table, in the silc_hash_table_rehash*. The affected file
3823 lib/silcutil/silchashtable.c.
3825 * Replaced hash_table_del_by_context calls from the server
3826 (when channel->user_list and client->channels) to the
3827 hash_table_del as it is sufficient and faster.
3829 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Added silc_hash_table_list, silc_hash_table_get and the
3832 SilcHashTableList structure to provide an alternative way to
3833 traverse the hash table. The affected files are
3834 lib/silcutil/silchashtable.[ch].
3836 * Changed the server's idlist routines to use the hash table
3837 routines to optimize the code.
3839 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Replaced the client entry's `channel' list and channel entry's
3842 `user_list' list to hash tables for optimized lookup. Changed
3843 the code to use the hash table interface around the code.
3844 Affected file lib/silcd/idlist.[ch].
3846 * Added `auto_rehash' boolean argument to the function
3847 silc_hash_table_alloc to indicate whether the hash table should
3848 auto-rehash when it thinks is appropriate time. It will
3849 increase the hash table size if the there is twice as much
3850 entries in the table than the size of the table, and will
3851 decrease the size if there are twice as less entries than
3852 the size of the table.
3854 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3858 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * silc_idcache_purge_by_context deletes the entry now by context
3861 as it is supposed to do. Affected file lib/silccore/idcache.c.
3863 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3864 client is not anymore valid (WHOWAS givens the info) and not
3865 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3867 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Removed the `data' and `data_len' arguments from the ID Cache
3870 interfaces and added `name' argument. ID Cache does not handle
3871 anymore the binary data only a names associated with given ID.
3873 * When hashing a Client ID with silc_hash_id the entire ID is
3874 not hashed anymore, instead only the hash of the Client ID is
3875 hashed. This way we can access the Client ID from the cache
3876 with Client ID but with the hash of the ID (which is a hash of
3877 the nickname) as well without any difference in performance.
3879 Added also silc_idcache_find_by_id_one_ext to do one on one
3880 searching when we have the actual ID. Added also function
3881 silc_hash_client_id_compare. The affected files are
3882 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3884 * When hashing the name associated with a ID it is always done
3885 in lowercase. This way we can access the cache without worrying
3886 about case-sensitivity, even though, for example nicknames are
3889 * Fixed a bug in server with channel message sending. It put
3890 wrong ID type as destination ID. The affected file
3891 silcd/packet_send.c.
3893 * silc_idcache_del_by_context now deletes from all hash tables
3894 by context. Affected file lib/silccore/idcache.c.
3896 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Changed the client library to use the new ID Cache interface.
3899 Changes around the source tree.
3901 * Added silc_hash_table_rehash_ext to rehash with specific
3902 hash function. Affected file lib/silcutil/silchashtable.[ch].
3904 * Added silc_hash_string_compare to compare two strings in the
3905 hash table. Affected file lib/silcutil/silcutil.[ch].
3907 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Added new function silc_idcache_del_by_context into the
3910 lib/silccore/idcache.[ch].
3912 * Changed the server's ID list routines to use the new ID Cache
3913 interface. Changes around the source tree.
3915 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Added silc_hash_table_del[_by_context]_ext functions in to the
3918 lib/silcutil/silchashtable.[ch].
3920 Removed silc_hash_table_find_all* routines and added new
3921 silc_hash_table_find_foreach to replace them.
3923 Added silc_hash_table_replace_ext function as extended
3924 replacing function. Separated the simple hash table interface
3925 from the extended hash table interface in the file
3926 lib/silcutil/silchashtable.h.
3928 * Fixed minor bugs and changed it to use some of the new
3929 hash table functions in lib/silccore/idcache.c
3931 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Added new function silc_hash_table_find_all to return all keys
3934 in the hash table by the specified key. As the hash table is
3935 collision resistant it also makes it possible to have several
3936 duplicate keys in the hash table. This function may be used to
3937 find all of the keys from the hash.
3939 Added user_context arguments to the SilcHashFunction,
3940 SilcHashCompare and SilcHashDestructor to deliver user specified
3943 Added new fuctions silc_hash_table_find[_all]_ext to do
3944 extended lookup with specified hash and compare functions and
3945 specified user contexts.
3947 Added new function silc_hash_table_add_ext to add the key
3948 with specified hash function and user context.
3950 Added new function silc_hash_table_foreach to traverse all
3951 entrys in the hash table. Added SilcHashForeach callback
3954 Added new function silc_hash_table_del_by_context to delete
3955 the entry only if the context associated with the key matches.
3957 Affected files are lib/silcutil/silchashtable.[ch].
3959 * Removed silc_hash_[server/client/channel]_id and added just
3960 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3961 silc_hash_id_compare to compare two ID's using as the hash table
3962 comparison function. Added also silc_hash_data to hash
3963 binary data and silc_hash_data_compare to compare it.
3965 * Removed silc_idlist_find_client_by_hash as it is not needed
3966 anymore. Affected file silcd/idlist.[ch].
3968 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3969 to use internally the SilcHashTable. The new ID Cache is a lot
3970 faster than the old one. Some of the ID Cache interface was also
3971 rewritten and obsolete and stupid functions were removed.
3973 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3975 * Added entry_count field to the SilcHashTable to keep the number
3976 of the entries in the table. Implemented the function
3977 silc_hash_table_rehash. Added new function
3978 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3980 Fixed a minor bug in silc_hash_table_free.
3982 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3983 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3984 into the lib/silcutil/silcutil.[ch].
3986 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Implemented a collision resistant hash table into the
3989 lib/silcutil/silchashtable[ch]. See the header and the source
3990 for the SilcHashTable API.
3992 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Merged dotconf version 1.0.2 into lib/dotconf.
3996 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Do not compile anything in lib/silcsim/* if the SIM support
3999 is not enabled. The tree should now compile without problems
4002 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Compiled the SILC under cygwin. Compiled and tested briefly
4005 without problems. More tests needed. The SIMs didn't compile
4008 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4010 * Fixed possible crash in silc_get_username in the
4011 lib/silcutil/silcutil.c.
4013 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Fixed a va_arg in silc/client_ops.c.
4017 * Oops, RC5 routines were named AES and caused some problems
4018 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4020 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Added new SilcIDIP structure into the lib/silccore/id.h and
4023 replaced the old `ip' fields from all SILC ID's to that type.
4024 This is a step towards IPv6 support.
4026 The silc_id_get_len takes now the ID as an extra argument.
4027 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4028 both IPv4 and IPv6 based ID's.
4030 The affected files are lib/silccore/id.[ch] and other files
4031 around the tree using these routines.
4033 * Removed the ID length arguments in server from various
4034 silc_server_send_notify_* routines -> they are not needed
4037 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Fixed memory leak in silc_encode_pem_file in the file
4040 lib/silcutil/silcutil.c.
4042 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Check minor version as well in the SKE. Affected files are
4045 silcd/protocol.c and lib/silcclient/protocol.c.
4047 * Added --identifier option to the server so that an identifier
4048 can be when creating the public key for the server. Affected
4049 file is silcd/silcd.c.
4051 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4052 lib/silccrypt/silcpkcs.c.
4054 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Register default ciphers and stuff when using -C option with
4057 the server. Affected file sildc/silcd.c.
4059 * Put back the servers public key filename format, it is better
4060 than the new one. For now, the client keys are saved with the
4061 new filename format. The affected file silc/client_ops.c.
4063 * Implemented the Cipher API for the rest of the ciphers that
4064 did not implement it or implemented it the wrong way.
4066 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Register default ciphers and stuff when using the -S option
4069 in the client. Affected file silc/silc.c. Same also when
4070 creating new key pair with -C option.
4072 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Fixed the silc_verify_public_key client operation function to
4075 save the public keys differently. The fingerprint is now
4076 used as filename and not the hostname. This way also the
4077 client keys are saved uniquely and not with hostnames. The
4078 affected file is silc/client_ops.c.
4080 * Trimmed the silc_hash_fingerprint function to remove extra
4081 whitespaces from the end of the fingerprint. The affected
4082 file is lib/silccrypt/silchash.c.
4086 * Added silc_cipher_register_default function to register all
4087 default ciphers. It can be used when configuration files
4088 does not exist and the application does not want any specific
4089 ciphers in any specific order.
4091 The SilcDList is now used as silc_cipher_list dynamically
4092 allocated cipher list. Removed the static list all together
4093 and now all ciphers must be allocated to the dynamic list.
4094 The silc_cipher_alloc routine was changed to check only the
4097 All silc_cipher_* routines that used to return int returns
4100 The affected files lib/silccrypt/silccrypt.[ch].
4102 * The same thing was done to silc_hash_* as for silc_cipher_*
4103 routines. Affected files lib/silccrypt/silchash.[ch].
4105 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4106 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4107 Added also silc_pkcs_[un]register[_default] functions.
4108 Removed the data_context from the PKCS API.
4110 * Added silc_hmac_register_default function to register default
4111 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4112 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4113 to unregister all hmacs at once.
4115 * Register the default ciphers, hash functions, PKCSs and HMACs
4116 if client's configuration file does not exist. The affected
4119 * The client did not load the hash functions from the SIM
4120 modules at all. Added support for this. Affected file is
4121 silc/clientconfig.c.
4123 * When decoding public key with silc_pkcs_public_key_decode, check
4124 the supported algorithm only if PKCS are registered. Affected
4125 file lib/silccrypt/silcpkcs.c. The same was done with the
4126 silc_pkcs_private_key_decode.
4128 * Fixed the SILC List routines to keep the list always in order.
4129 It used to change the list's order when traversing the list but
4130 not it preserves the order. Affected file lib/trq/silclist.h.
4132 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Added the client library to use the SilcSocketConnection's
4135 reference counter (by silc_socket_dup) to prevent the bug that
4136 the socket object may be freed underneath async operation.
4138 * The name resolv library checking fixes in the configure.in.pre.
4141 * Created new version of the protocol drafts for future
4142 development. The -03 drafts are the ones that will be changed
4143 in the trunk now and the -02 will remain as they are.
4145 * Send list of CUMODE notifys to the router when announcing
4146 the channel users to the router. Affected file silcd/server.c.
4147 If the router receiving channel founder CUMODE for a channel
4148 that already has channel founder it will send CUMODE notify
4149 to the sender to remove the channel founder rights from the
4150 announced client. Affected file silcd/packet_receive.c.
4152 * The CUMODE notify may now use Server ID as well as the entity
4153 who changes the mode. Updated protocool specs.
4155 * Updated INSTALL and README files.
4157 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4159 * New web pages in the http://silc.pspt.fi. The pages was
4164 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Implemented the [DenyConnectin] config section in the server.
4167 Added silc_server_config_denied_conn to check whether incoming
4168 connection is denied. Affected file silcd/serverconfig.[ch].
4170 * Do not check the ports when checking the incoming configuration
4171 data if the port is 0, meaning any. Affected file is
4172 silcd/serverconfig.c.
4174 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Fixed buffer overflow in silc_string_compare in the file
4177 lib/silcutil/silcutil.c.
4179 * Fixed double free in silc_server_command_leave in the file
4182 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Fixed the version checking in the server. Affected file is
4187 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Fixed the configuration data fetching when accepting new
4190 connections in the server. Affected file silcd/server.c.
4192 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Added `sender_entry' argument to the function
4195 silc_server_packet_relay_to_channel so that we can check
4196 whether some destination actually belongs to the same route
4197 the sender belongs (ie, we must not resend the packet to the
4198 sender). Affected file silcd/packet_send.[ch].
4200 * Added `servername' field to the SilcClientEntry in the server
4201 to hold the name of the server where client is from. Affected
4202 file is silcd/idlist.h.
4204 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Moved the channel message encrypting in the router betwen
4207 router connections from silc_server_channel_message to the
4208 silc_server_packet_relay_to_channel since we want to check
4209 whether we have anybody channel before encrypting anything.
4210 Affected files silcd/packet_[receive/send].c.
4212 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Fixed the [AdminConnection] server config section to support
4215 multiple entries. Affected file silcd/serverconfig.c.
4217 * Added support into the server to check the validity of the
4218 incoming connection before executing any KE or authentication
4221 * The connection configuration is now saved to the KE and
4222 connection auth protocol contexts and not fetched anymore in
4223 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4225 * The local hosts listenning address and port is also resolved
4226 now when starting the server. We want to have the socket object
4227 to include the real address and port for the listener. Added
4228 new function silc_net_check_local_by_sock into the files
4229 lib/silcutil/silcnet.[ch].
4231 * Fixed a broadcast bug in server -> do not broadcast if we
4234 * Fixed a routing bug. Do not route broadcast packets ever.
4235 Broadcast packets must be processed always and not routed since
4236 they may be destined to some other host than yourself and thus
4237 would get routed without no good reason. Affected file is
4240 * Added function silc_server_config_is_primary_route to check
4241 whether primary router connection has been configured (a router
4242 configuration that we are initiating). If there is not, we
4243 will assume that there is only two routers in the SILC network
4244 and we will use the incoming router connection as our primary
4245 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4247 * Changed the order of the broadcasting. Broadcast _after_ the
4248 packet has been processed not before. Affected file is
4251 * Fixed a [ClientConnection] parsing bug. The port was never
4252 parsed correctly thus resulting to port 0. Affected file
4253 silcd/serverconfig.c.
4255 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4256 argument and did not set the broadcast packet flag. Affected
4257 file silcd/packet_send.c. Fixed same bug in the function
4258 silc_server_send_notify as well.
4260 * If we receive NEW_ID packet for our own ID in the server, ignore
4263 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Removed the nickname from the Private Message Payload.
4268 Updated the code and the protocol specs.
4270 * Updated protocol specs for submitting to the IETF.
4272 * Tweaked the Random Number Generator a bit. Affected file
4273 lib/silccrypt/silcrng.c. Exported a new function
4274 silc_rng_[global]_add_noise which can be used to add more
4277 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Do not parse packets with different timeout when protocol
4280 is active -> may cause problem with rekey. Affected file
4283 * When server receives signoff notify it must not create
4284 new channel key if the client is on any channels since the
4285 sender of the signoff notify will create it.
4287 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * Added printing of error messages during SKE protocol from the
4290 failure packet sent by server during SKE. Affected file
4293 * Removed the client's failure_callback handling with timeout
4294 and handle it immediately when received.
4296 * The SKE library returned wrong type in SUCCESS and FAILURE
4297 packets. They must be 32 bit MSB not 16 bit MSB.
4299 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Ok, rewrote the logic of the re-key and now it seems to work.
4302 I tested it on high traffic with frequent re-keys without
4303 problems. Added hmac_receive (and renamed hmac to hmac_send)
4304 in SilcClientConnection in lib/silcclient/client.h and
4305 in SilcIDListData in silcd/idlist.h. Also, removed the
4306 SilcPacketParserContext's cipher and hmac fields as they are
4307 not needed anymore and actually caused some problems when
4308 the ciphers and hmac's changed underneath the packet parser.
4310 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * If re-key protocol is active then process the incoming packets
4313 synchronously since we must assure that icoming packets encrypted
4314 with the old key is processed before the new keys is set to
4315 use. This is true other packets than for REKEY packets.
4316 Affected file silcd/server.c. The same was done to client library
4317 as well, affected file lib/silcclient/client.c.
4319 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Fixed bug in client and server to accept the force send if
4322 the packet is send from silc_[server/client]_packet_process
4323 function. Otherwise the packets are never delivered, oops.
4325 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Disable force sending of packets when REKEY protocol is active.
4328 We must assure that no packet is sent directly when rekey is
4329 performed. All packets must be sent through packet queue.
4330 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4331 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4332 function is silc_[server/client]_packet_send_real to check
4335 * Replaced the SIM paths from example config files to
4336 /usr/local/modules. Also, make install creates now
4337 /usr/local/silc/logs directory to hold all the SILC server
4340 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Made the configure.in.pre work on Solaris. Patch by salo.
4344 * Made all ciphers compatible with non-x86 machines. Defined
4345 CBC mode macros into lib/silccrypt/ciphers_def.h.
4347 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Fixed the make install.
4351 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * When MAC computation fails the silc_packet_decrypt returned 0
4354 even though it was supposed to return -1. Fixed this. The
4355 affected file is lib/silccore/silcpacket.c.
4357 * Do not replace the config files in /etc/silc (in make install)
4358 if they already exist. Affected file ./Makefile.am.
4360 * Do not send re-key packets immediately but through packet queue.
4361 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4363 * Changed silc_net_check_host_by_sock to return FALSE if the
4364 IP/DNS could not be resolved. Though, it returns the IP address
4365 now even if it could not resolve it (but returns also FALSE).
4366 Affected file lib/silcutil/silcnet.[ch].
4368 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Added silc_pkcs_decode_identifier to decode the public key's
4371 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4372 Added also silc_pkcs_free_identifier. Added also new context
4373 SilcPublicKeyIdentifier.
4375 * Added -S option to the silc client. It is used to dump the
4376 contents of the specified public key file.
4378 * Changed the PKCS api to return the public key length when
4379 setting the public key.
4381 * Fixed a fatal bug in the public and private key file loading.
4382 Affected file lib/silccrypt/silcpkcs.c.
4384 * Execute the packet parsing for client with zero (0) timeout
4385 if the protocol is active. Affected file silcd/server.c.
4387 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Made the key generation options to the silcd program. Added
4390 -C option, equivalent to client's option.
4392 * Added new [ServerKeys] config section to the server. It
4393 configures the server's public and private key.
4395 * Defined generic Public Key Payload into the protocol
4396 specification to send specific type of public keys and
4399 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4400 public key or certificate.
4402 * Implemented the GETKEY command to the server and to the
4403 client library and on user interface.
4405 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Made preliminary `make install' work.
4409 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Added SilcServerRekey context into silcd/idlist.h.
4413 * Added the PFS support as defined in the specification to the
4414 SKE protocol. Affected files lib/silcske/*.c.
4416 * Added `ske_group' field to the SilcServerRekey context to hold
4417 the number of the SKE group that is used with PFS in re-key.
4418 Affected file silcd/idlist.h.
4420 * Added PFS re-key support to the server. Affected file is
4423 * Added silc_protocol_cancel to cancel execution of the next
4424 state of the protocol. Affected file is
4425 lib/silccore/silcprotocol.[ch].
4427 * Added the re-key support with and without PFS to the client
4428 library. Re-key is performed once in an hour, by default.
4430 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4431 Added silc_client_rekey_callback and silc_client_rekey_final.
4432 Affected files are lib/silcclient/protocol.[ch] and
4433 lib/silcclient/client.[ch].
4435 * Removed the `hmac_key' and `hmac_key_len' fields from the
4436 SilcClientConnection structure; not needed. Affected file is
4437 lib/silcclient/client.h.
4441 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Do not ask whether user wants to use the negotiated private key
4444 for private messages, just use it. Affected file is
4445 silc/local_command.c.
4447 * Added `send_enc_key' and `enc_key_len' fields to the
4448 SilcIDListData structure since they are needed in the re-key
4449 phase. Affected file is silcd/idlist.[ch].
4451 * Implemented the simple re-key protocol into the server.
4452 Affected files silcd/server.c and silcd/protocol.[ch]. The
4453 re-key will be performed once in an hour, by default.
4455 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4456 Added silc_server_rekey, silc_server_rekey_callback and
4457 silc_server_rekey_final.
4459 * Removed Tunneled flag from the protocol. Updated the code
4460 and the specifications.
4462 * Adde `pfs' field to the SilcIDListData to indicate whether
4463 the PFS is to be performed in the re-key. Affected file is
4466 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4469 int64 of at least the xintXX size. If void * is less that 4
4470 bytes uint32 * will be used. Defined bool as boolean.
4472 * Changed _ALL_ unsigned long and unsigned int to uint32,
4473 unsgined short to uint16 in the source tree.
4475 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4476 not handle clients that has entry->data.registered == FALSE.
4477 They are not in the network anymore. Affected file is
4480 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Implemented the sending of the SERVER_SIGNOFF notify in the
4483 server. Affected file is silcd/server.c.
4485 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4486 Added also silc_notify_payload_encode_args into the
4487 lib/silccore/silcnotify.[ch].
4489 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4490 Affected file silcd/packet_receive.c.
4492 * Implemented the SERVER_SIGNOFF notify handling in the client
4493 library. Affected file lib/silcclient/client_notify.c. Also,
4494 implemnted the printing of the SERVER_SIGNOFF info to the
4495 application. Affected file silc/client_ops.c.
4497 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4498 if the deleting was successful. Affected file silcd/idlist.[ch].
4500 * Added support for public key authentication in the connection
4501 authentication protocol in the client library. Affected file
4502 lib/silcclient/protocol.c.
4504 * Changed the server's silc_idlist_get_clients_by_* interface
4505 to support already allocated array so that new entries may be
4506 added to pre-allocated array. Affected file silcd/idlist.[ch].
4507 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4508 and command replies.
4510 * All command reply functions in the server now calls the
4511 pending command callback even if error occured. This way the
4512 error will be delivered to the client as well. Affected files
4513 silcd/command.c and silcd/command_reply.c.
4515 * Fixed INFO command to return local server's info if no server
4516 was provided. Affected file lib/silcclient/command.c.
4518 * Removed RESTART command for good. Updated the code and the
4521 * Rewrote parts of the task system. It is a bit simpler now.
4522 Removed unsued task priorities. The affected files are
4523 lib/silcutil/silctask.[ch].
4525 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Moved the USERS printing from the library to the application.
4528 Affected files lib/silcclient/command.c and silc/client_ops.c.
4530 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Added channel key re-key support. The re-key is perfomed
4535 only by the router and is done once in an hour. Added `rekey'
4536 field to the SilcChannelEntry in the server. Affected files
4537 silcd/server.c and silcd/idlist.h.
4539 * Added silc_task_unregister_by_context into the file
4540 lib/silcutil/silctask.[ch].
4542 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Added SILC_UMODE_GONE mode to indicate when the client is not
4545 present in the SILC network. Added also support to the local
4546 command AWAY that will set this mode. Added support of showing
4547 "xxx is gone" in WHOIS command. The USERS command shows the
4548 gone status as well.
4550 * Fixed setting server and router operator privileges in the
4551 server's UMODE command. Affected file silcd/command.c.
4553 * Merged the SKE KE1 and KE2 payloads into one payload. The
4554 new KE payload is equivalent to the old KE2 payload.
4556 Cleaned up the SKE Start Payload parsing. It now uses the
4557 simple buffer unformatting to do the parsing. A lot faster
4560 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4561 to the SKE that is used to indicate whether both of the SKE
4562 parties should perform authentication. By default only the
4563 responder performs authentication. By setting this flag also
4564 the initiator must do authentication. By default it is unset
4565 since in normal SKE case, client to server connection, only
4566 the responder should do authentication. When doing SKE between
4567 two clients both should perform authentication. Updated the
4568 code and the protocol specs.
4570 * A little fix to IDENTIFY command in the server. Search the
4571 client first by hash not nickname. Affected file is
4574 * Fixed the silc_client_close_connection to support closing
4575 the client to client connections wihtout deleting too much
4576 data. Affected file lib/silcclient/client.c.
4578 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4579 are received if protocol used to be active but is not anymore
4580 the application would crash due to NULL pointer dereference.
4581 Affected files silcd/server.c and lib/silcclient/client.c.
4583 * Added `hash' field to the SilcClientConnection to include
4584 the hash function negotiated in the SKE protocol.
4586 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4587 to set the channel founder authentication data. A client can
4588 claim the founder rights later by providing the authentication
4589 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4590 This way the channel founder can regain the channel founder
4591 privileges even it is left the channel. This works only on
4592 local server and the client must be connected to the same
4593 server to be able to regain the founder rights. Updated the
4594 protocol specs accordingly.
4596 Added support to the CMODE command in the client to set the
4597 founder auth data. Read the README to see how to set it.
4599 Added support to the CUMODE command to claim the founder
4600 rights. Read the README to see how to do it.
4602 Added support for the founder authentication to the Channel
4603 Entry in the server. Affected file silcd/idlist.h.
4605 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4606 server's CMODE command. Affected file silcd/command.c.
4608 * Added the following new functions into lib/silccore/silcauth.[ch]:
4609 silc_auth_get_method and silc_auth_get_data.
4611 * The server now saves the remote hosts public key to the
4612 SilcIDListData pointer. Affected file silcd/protocol.c.
4614 * The normal server now does not remove the channel entry from
4615 the cache if the founder authentication data is set. It used
4616 to remove it if the founder was the last one on the channel on
4617 the server and left the channel. The auth data is saved and
4618 if the channel is re-joined later the old entry is used with
4619 the old auth data. Affected files silcd/command_reply.c and
4622 * Removed the `pkcs' field from the SilcIDListData structure
4623 in the server; it is not used. Affected file silcd/idlist.h.
4625 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Fixed packet processing on slow links. Partial packets were
4628 never re-processed because the incoming data buffer was cleared
4629 by the application. Application must not directly clear the
4630 sock->inbuf, the packet processing routines handle it. Fixed
4631 this in client library and in server.
4633 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Fixed the WHOIS and IDENTIFY send reply function to really
4636 check whether to send list or just one entry. Affected file
4639 * Cleaned up the LEAVE command's channel key distribution. The
4640 affected file silcd/command.c.
4642 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4643 can enforce the channel mode as well. In that case the ID
4644 includes the ID of the server. The code now enforces the
4645 mode change if the router have different mode than the server.
4647 * The notify client operation with CMODE_CHANGE notify can now
4648 return NULL client_entry pointer if the CMODE was not changed
4649 by client. Application must check for this.
4651 * Added <Server ID> argument to INFO command to support server
4652 info fetching by Server ID.
4654 * Added silc_server_announce_get_channel_users to get assembled
4655 packets of channel users of the specified channel. Affected
4656 file silcd/server.[ch].
4658 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4659 was freed underneath the ID Cache.
4661 * Re-announce clients when the server received CHANNEL_CHANGE
4662 notify from the router. Affected file silcd/packet_send.c.
4664 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4667 crashed since it did not handle the fact that there is no cipher
4668 called "3" and didn't check the error condition. Now fixed.
4670 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4671 flag. It can be used to send message requests.
4673 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Implemented the RESTART command in the client.
4677 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4678 notice type messages. Added notice printing to the user
4681 * The channel keys are not re-generated if the channel's mode
4682 is PRIVKEY, ie private key on the channel exists. Affected
4683 files silcd/server.c and silcd/command.c.
4685 * Fixed a little bug in channel message delivery when channel
4686 private keys are set in the server. Affected file is
4687 silcd/packet_send.c.
4689 * Changed the setting on channel->on_channel = TRUE from the
4690 silc_client_save_channel_key to the JOIN command reply. The
4691 key payload is not received if the private channel key is set.
4692 Affected file lib/silcclient/command_reply.c and the
4693 lib/silcclient/client_channel.c.
4695 * When the CMODE_CHANGE notify is sent and the channel private
4696 key mode is removed the channel key must be re-generated in
4697 other cells as well. Added this support for the router in the
4698 silcd/packet_receive.c.
4700 * Added new local command NOTICE to send notice message on
4701 channel. Affected file silc/local_command.[ch].
4703 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Added new local command ME to the client. It is used to send
4706 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4707 some action. Affected file silc/local_command.[ch].
4709 * Changed channel_message and private_message client operations
4710 to deliver the message flags to the application. Added also
4711 the `flags' arguments to the silc_client_send_channel_message
4712 and silc_client_send_private_message functions. Affected file
4715 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4717 * Redefined the Private Message Payload to support private message
4718 keys and to support the new private message flags. Updated
4719 the protocol specs. Flags makes it possible to have for example
4720 CTCP style messages.
4722 * Added new type SilcPrivateMessagePayload and defined an API
4723 for it in the lib/silcclient/silcprivate.[ch].
4725 * Tested private message private keys successfully. Tested the
4726 private message key set, unset and list commands with the new
4729 * Redefined the Channel Message Payload to include the channel
4730 message flags (equal with private message flags) to support
4731 for example CTCP style messages.
4733 * Defined some of the message (for channel and private message)
4734 flags. Updated the protocol specs and added the flags to the
4735 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4737 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Added SilcKeyAgreementStatus type to the key agreement routines
4740 to indicate the current status and error if one occured.
4741 The status types are defined in the lib/silcclient/silcapi.h.
4743 * Added new local command KEY that is used to set and unset private
4744 keys for channels, set and unset private keys for private messages
4745 with remote clients and to send key agreement requests and
4746 negotiate the key agreement protocol with remote client. The
4747 key agreement is supported only to negotiate private message keys,
4748 it currently cannot be used to negotiate private keys for channels,
4749 as it is not convenient for that purpose.
4751 * Fixed a minor pending callback setting bug in the function
4752 silc_client_get_client_by_id_resolve, now the function works.
4753 Affected file lib/silcclient/idlist.c.
4755 * Added function silc_net_get_local_port to get local bound
4756 port by socket. Added to lib/silcutil/silcnet.[ch].
4758 * Added `sockets' and `sockets_count' fields to the SilcClient
4759 object. They hold the sockets of the listenning sockets in
4760 the client. Listenning sockets may be for example the key
4761 agreement server. Affected file lib/silcclient/client.[ch].
4762 Added functions the silc_client_add_socket and the
4763 silc_client_del_socket. They are exported to the application
4766 * Added ~./silc/clientkeys to support other client's public keys.
4768 * Renamed verify_server_key client operation to verify_public_key
4769 and added one argument to indicate the type of the connection
4770 (server, client etc.).
4772 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Added silc_server_connection_auth_request to handle the
4775 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4776 silcd/packet_receive.[ch].
4778 * Added silc_server_send_connection_auth_request into the
4779 silcd/packet_send.c to send the connection auth request packet.
4781 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4784 * Fixed the public key authentication in responder side in the
4785 server. The `auth_data' pointer includes the SilcPublicKey
4786 not the path to the public key. Affected file silcd/protocol.c.
4788 * Implemented the public key authentication in the initiator side
4789 in the server. Affected file silcd/protocol.c.
4791 * Removed the [RedirectClient] config section from the server
4792 configuration. Is not needed and I don't want to implement it.
4794 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Cleaned up the CMODE command in the server. It now works
4797 correctly and supports all the modes defined in the protocol.
4798 Affected file is silcd/command.c.
4800 * Added `hmac_name' field to the SilcChannelEntry in the server
4801 to hold the default HMAC of the channel. It can be set when
4802 creating the channel (with JOIN command). Affected files
4805 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4806 type to indicate the change of the current cipher and hmac
4807 on the channel. Client can safely ignore the <cipher> argument
4808 (if it chooses to do so) since the CHANNEL_KEY packet will
4809 force the channel key change anyway. The <hmac> argument is
4810 important since the client is responsible of setting the new
4811 HMAC and the hmac key into use.
4813 * Fixed the CMODE command in the client library as well.
4815 * Tested CMODE command in router environment successfully.
4817 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Show the version of the remote client (or server) when connecting
4820 to the server. It is logged to the log file. Affected file
4821 is silcd/protocol.c.
4823 * Fixed the KILLED notify handling in the client library. The
4824 client must be removed from all channels when receiving the
4827 Also, do not remove the client entry when giving the KILL
4828 command but when the KILLED notify is received.
4830 * Removed silc_idlist_find_client_by_nickname from the server.
4831 Not needed anymore. Affected files silcd/idlist.[ch].
4833 * Implemented the CHANNEL_CHANGE notify type handling to the
4834 server. Affected file silcd/server.c.
4838 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added silc_server_send_notify_invite to send the INVITE
4841 notify between routers.
4843 * Implemented the INVITE command correctly to the server.
4845 * Implemented the INVITE notify type handling in the server.
4847 * Implemented the INVITE command to the client library and on the
4850 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added function silc_server_get_client_resolve to find the
4853 client entry by ID from all ID lists and then resolve it
4854 (using WHOIS) if it cannot be found. Affected file is
4857 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Implemented the BAN command to the client library.
4861 * The JOIN command in the server now checks the invite list
4864 * Changed the silc_command_reply_payload_encode_va and the
4865 silc_command_payload_encode_va to support that if argument is
4866 NULL it ignores and checks the next argument. Affected file
4867 lib/silccore/silccommand.c.
4869 * Added silc_server_send_notify_ban to send the BAN notify
4870 type between routers.
4872 * Chaned the silc_notify_payload_encode to support that if
4873 argument is NULL it ignores and checks the next argument.
4874 Affected file lib/silccore/silcnotify.c.
4876 * Tested ban lists in router environment successfully.
4878 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Implemented BAN command to the server, in silcd/command.[ch].
4882 * Removed the BAN and INVITE_LIST modes from the CMODE command
4885 * Added function silc_string_match to regex match two strings.
4886 Affected files lib/silcutil/silcutil.[ch].
4888 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Redefined parts of the SilcChannelEntry in the server to support
4891 the new ban and invite lists.
4893 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Redefined the INVITE command. The same command can be used to
4896 invite individuals to the channel but also to manage the invite
4897 list of the channel (to add to and remove from the invite list).
4898 Updated the protocol specs.
4900 * Added new command SILC_COMMAND_BAN that can be used to manage
4901 the ban list of the channel. Updated the protocol specs.
4903 * Removed the channel modes: the SILC_CMODE_BAN and the
4904 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4905 in the CMODE command. The equivalent features are now available
4906 using INVITE and BAN commands. Updated the protocol specs.
4908 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4909 in the network about change in the current ban list. The notify
4910 type is not used by the client.
4912 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4913 support the invite lists.
4915 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Added new function silc_string_regexify that converts string
4918 including wildcard characters into regex string that can
4919 be used by the GNU regex library. Added into the file
4920 lib/silcutil/silcutil.[ch].
4922 Added silc_string_regex_combine to combine to regex strings
4923 into one so that they can be used as one regex string by
4924 the GNU regex library. Added into the file
4925 lib/silcutil/silcutil.[ch].
4927 Added silc_string_regex_match to match two strings. It returns
4928 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4930 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Imported GNU regex to the soruce tree into lib/contrib.
4933 Fixed some compiler warning from the regex.c.
4935 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed MOTD command in the server to work in router environment.
4939 * Fixed the MOTD command in the client library to support
4940 the server argument in the command.
4942 * Added `nickname_len' argument to the silc_idlist_add_client
4943 in the server, as the `nickname' argument may be binary data
4946 * Added silc_idlist_get_channels to return all channels from
4949 * Implemented LIST command to the server. Affected file is
4952 * Implemented the LIST command to the client library and on the
4955 * Added [<user count>] argument to the LIST command reply.
4956 With private channels the user count is not shown.
4958 * Updated TODO and README.
4960 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * The client entry's data.registered must be TRUE even with
4963 global client entry on global client list. The data.registered
4964 is used to check whether the client is anymore in the network,
4965 for example with WHOWAS command so it must be valid.
4967 * Fixed the WHOWAS command in the server. It now actually works
4968 in router environment. Added function into silcd/command_reply.c
4969 silc_server_command_reply_whowas_save.
4971 * Added silc_idlist_purge function to the silcd/idlist.c
4972 to periodically purge the ID Cache.
4974 * Fixed INFO command in the server. It works now in router
4975 environment. Added <server name> argument to the INFO command
4976 reply. Updated the protocol specs.
4978 * Fixed minor bug in silc_idcache_purge to not purge if the
4979 expire value is zero.
4981 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4982 they were buggy because of the WHOWAS information.
4984 * Fixed local command MSG to handle the async resolving of
4985 the remote client properly. It used to fail the first MSG.
4986 Affected file silc/local_command.c.
4988 * Added `data_len' field to SilcIDCache context.
4990 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Update TODO. Todo in commands in the server.
4994 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4997 used by routers as broadcast packet to inform other routers
4998 about the changed user mode.
5000 Implemented the notify handling in the server. Affected file is
5001 silcd/packet_receive.c. Added the function
5002 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5004 * Added new generic Channel Payload and deprecated the New Channel
5005 Payload. The New Channel Payload is now the generic Channel
5008 * Added new argument `mode' to the silc_server_send_new_channel
5009 as it is required in the Channel Payload now.
5011 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5012 and created a new and real SilChannelPayload to represent the
5013 new generic Channel Payload. Implemented the encode/decode
5014 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5016 * Added silc_server_get_client_channel_list to return the list
5017 of channels the client has joined for WHOIS command reply.
5018 Affected file silcd/server.[ch].
5020 * Implemented the channel list sending in the WHOIS command reply
5021 in server and in the client.
5023 Implemented the channel list displaying on the user interface
5024 as well. Affected file silc/client_ops.c.
5026 * Added silc_channel_payload_parse_list to parse list of Channel
5027 Payloads. It returns SilcDList list of SilcChannelPayloads.
5028 Client for example can use this function to parse the list of
5029 channels it receives in the WHOIS command reply. The caller
5030 must free the list by calling silc_channel_payload_list_free.
5031 Affected files lib/silccore/silcchannel.[ch].
5033 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Added one new argument <user mode> to the WHOIS command reply
5036 to return the mode of the user in SILC. Updated the protocol
5039 Implemented it to the server and client.
5041 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Fixed the mode printing on the user interface on joining.
5044 Affected file silc/client_ops.c.
5046 * Implemented the UMODE command and user modes in general to the
5047 client library and to the user interface.
5049 * Implemented the UMODE command to the server.
5051 * The server now sends UNKNOWN_COMMAND error status if client sends
5052 unknown command. Affected file silcd/command.c.
5054 * All server commands now handle the command identifier the right
5055 way when sending the command reply to the client. The client can
5056 use to identify the command replies with the identifier.
5058 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Added silc_server_get_client_route to resolve the route to
5061 the client indicated by the client ID. Affected file is
5064 * Added silc_server_relay_packet as general function to relay
5065 packet to arbitrary destination. This deprecates functions
5066 like _send_private_message_key, _relay_notify etc. Affected
5067 file is silcd/packet_send.[ch].
5069 Removed silc_server_send_key_agreement,
5070 silc_server_send_private_message_key and
5071 silc_server_packet_relay_notify functions from the file
5072 silcd/packet_send.[ch].
5076 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5077 server. Affected file silcd/packet_receive.[ch].
5079 * Implemented the KILL command to the client. Implemented the
5080 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5081 Affected files lib/silcclient/command[_reply].c and
5082 lib/silcclient/client_notify.c. Implemented the KILL notify
5083 printing in the user inteface.
5085 * Fixed a lot silc_parse_nick memory leaks from the client
5086 library in the file lib/silcclient/command.c.
5088 * Changed the silc_server_send_notify_on_channels's `sender'
5089 argument from SilcSocketConnection to SilcClientEntry to
5090 check the sender as entry and not as connection object and not
5091 to send to the client provided as argument. The affected file
5092 is silcd/packet_send.[ch].
5094 * The notify packets that are destined directly to the client used
5095 to not to be processed by the server. Now changed that and the
5096 server processes all notify packets. After relaying the packet
5097 to the client the notify packet is processed in the server.
5099 * The silc_server_free_client_data now checks whether there is
5100 pending outgoing traffic for the client and purges the data to
5101 the network before removing the client entry.
5103 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5105 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5106 an client is killed from the SILC Network. Updated the protocol
5109 Added new function silc_server_send_notify_killed to the
5110 silcd/packet_send.[ch].
5112 * Added function silc_server_packet_relay_notify to relay notify
5113 packets that are destined directly to a client. In this case
5114 the server does not process the notify packets but merely relays
5115 it to the client. Affected file silcd/packet_send.[ch].
5117 Added also silc_server_packet_process_relay_notify to check
5118 whereto relay the notify. Affected file is
5119 silcd/packet_receive.[ch].
5121 * Implemented the KILL command to the server.
5125 * Added the backup schema desgined last fall to the protocol
5126 specs for everyone to see. The specification is in the
5127 *-spec-xx.txt draft and the packet type definitions for the
5128 backup routers is in *-pp-xx.txt draft. Thusly, added also
5129 new packet type SILC_PACKET_CELL_ROUTERS.
5131 * A big security problem in the implementation discovered. The
5132 signoff of an client did not cause new channel key generation
5133 which it of course should've done. The channel keys must be
5134 always re-generated when client leaves (or signoffs) the channel.
5135 The silc_server_remove_from_channels funtion now handles
5136 the channel key re-generation.
5138 * Added `sender' argument to the silc_server_send_notify_on_channels
5139 to not to send the client provided as argument. Affected file
5140 silcd/packet_send.[ch].
5142 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Implemented OPER and SILCOPER commands into the server and
5147 * Added silc_auth_verify and silc_auth_verify_data to verify
5148 the authentication directly from the authentication payload.
5149 It supports verifying both passphrase and public key based
5150 authentication. Affected file lib/silccore/silcauth.[ch].
5152 * Added `hash' field to the SilcIDListData structure. It is the
5153 hash negotiated in the SKE protocol. Affected file is
5156 * Slight redesigning of the SilcAuthPayload handling routines.
5157 Do not send SilcPKCS but SilcPublicKey as argument.
5159 * Implemented the public key authentication support to the
5160 serverconfig. The public key is loaded from the provided path
5161 and saved as authentication data to void * pointer. Thus,
5162 changed the unsigned char *auth_data to void *auth_data;
5164 * Fixed SHUTDOWN command to send the reply before the server
5165 is shutdown. :) Affected file silcd/command.c.
5167 * Fixed fatal bug in CONNECT command. The hostname was invalid
5168 memory and server crashed. Affected file silcd/command.c.
5170 * Fixed fatal bug in CLOSE command. The server_entry became
5171 invalid but was referenced later in the command. Affected file
5174 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Fixed fatal bug in failure packet handling. Server ignored
5177 the failure and thus crashed when it came.
5181 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5184 that the command may be executed only once in (about) 2 seconds.
5185 The old SILC_CF_LAG flag is same but allows command bursts up
5186 to five before limiting.
5188 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5189 server code. Various commands now includes the CF_LAG_STRICT
5190 flag to disallow any kind of miss-use of the command.
5192 * Fixed the silc_buffer_unformat to not to allocate any data
5193 if the length of the data is zero. It used to allocate the
5194 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5196 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Changed the format of AdminConnection configuration section
5199 in the server. Added username of the admin to the format.
5200 Affected files silcd/serverconfig.[ch].
5202 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5203 to return admin configuration data by host, username and/or
5206 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Implemented WHOWAS command to the server. Added the functions:
5210 silc_server_command_whowas_parse,
5211 silc_server_command_whowas_send_reply,
5212 silc_server_command_whowas_from_client and
5213 silc_server_command_whowas_from_server
5215 * Added <Client ID> argument to the WHOWAS command reply. Updated
5216 the protocol specs accordingly.
5218 * Implemented WHOWAS command and command_reply to the client
5221 Implemented the WHOWAS printing on the user interface.
5223 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Added new argument to the WHOWAS command reply, the real name.
5226 It is an optional argument. Updated the protocol specs.
5228 * Added SilcIDCacheDestructor callback that is registered when
5229 the SilcIDCache is allocated. The callback is called when
5230 an cache entry in the ID Cache expires, or is purged from the
5231 cache. Added into lib/silccore/idcache.[ch].
5233 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5234 to destruct the client entries when the cache entry expires.
5235 Other ID Cache's in server and in the client library ignores
5238 * If the ID Cache entry's `expire' field is zero then the entry
5239 never expires. Added boolean `expire' argument to the
5240 silc_idcache_add function in the lib/silccore/idcache.[ch].
5241 If it is TRUE the default expiry value is used.
5243 * Added silc_server_free_client_data_timeout that is registered
5244 when client disconnects. By default for 5 minutes we preserve
5245 the client entry for history - for WHOWAS command.
5247 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Added support to the server to enforce that commands are not
5250 executed more than once in 2 seconds. If server receives
5251 commands from client more frequently, timeout is registered
5252 to process the commands. Affected file silcd/command.c.
5253 Added new function silc_server_command_process_timeout.
5255 * Changed NICK_NOTIFY handling in client library to check that
5256 if the client's nickname was changed, so there is no need to
5257 resolve anything from the server.
5259 * Removed error printing from the WHOIS and IDENTIFY commands.
5260 If error occurs then it is ignored silently in the client library.
5261 The application, however, may map the received error to
5262 human readable error string. The application currently maps
5263 the NO_SUCH_NICKNAME error to string.
5265 * Made the command status message public to the application. Moved
5266 them from lib/silcclient/command_reply.c to
5267 lib/silcclient/command_reply.h. The application can map the
5268 received command status to the string with the
5269 silc_client_command_status_message function.
5271 * Added check to the server to check that client's ID is same
5272 as the Source ID in the packet the client sent. They must
5275 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Added dist-bzip hook to the Makefile.am to make bzip2
5278 compressed distributions.
5280 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Server now enforces the maximum length for the nickname and
5283 the channel as protocol specification dictates. 128 bytes for
5284 nickname and 256 bytes for channel name.
5286 * Moved the WHOIS printing to the application. The client libary
5287 does not print out the WHOIS information anymore, the application
5288 must do it. Renamed silc_client_command_reply_whois_print to
5289 the silc_client_command_reply_whois_save.
5291 The client's idle time is also sent to the application now, and
5292 the idle is shown on screen.
5294 * Added silc_client_command_reply_identify_save to save the
5295 received IDENTIFY entries.
5297 * Do not check for channel private keys in message sending and
5298 reception if the channel does not have the PRIVKEY mode set.
5299 Affected file lib/silclient/client_channel.c.
5301 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5304 just surfaced after chaning the JOIN procedure.
5306 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Added silc_client_get_clients_by_list to get client entries
5309 from Client ID list, that is returned for example by JOIN
5310 and USERS command replies. The application should use this
5311 function for example when JOIN command reply is received to
5312 resolve the clients already on the channel (library does not
5313 do that anymore as USERS command reply is not used in the JOIN
5314 procedure anymore). Affected files lib/silcclient/silcapi.h and
5315 lib/silcclient/idlist.c.
5317 * JOIN command reply and USERS command reply returns now SilcBuffer
5318 pointers instead of unsigned char pointers when returning
5319 the client list and mode list.
5321 * Added <Client ID> argument to the JOIN command reply, mainly
5322 for the server to identify for which client the command was
5323 originally sent. Updated protocol specs accordingly.
5325 * Added SilcDlist private_key pointer to the SilcChannelEntry
5326 in the client to support the channel private keys. Affected
5327 file is lib/silcclient/idlist.h.
5329 * Added SilcChannelPrivateKey argument to the function
5330 silc_client_send_channel_message so that application can choose
5331 to use specific private ke if it wants to. If it is not provided,
5332 the normal channel key is used, unless private keys are set.
5333 In this case the first (key that was added first) is used
5334 as the encryption key.
5336 * Implemented the support for channel private key handling.
5337 Implemented the following functions:
5339 silc_client_add_channel_private_key,
5340 silc_client_del_channel_private_keys,
5341 silc_client_del_channel_private_key,
5342 silc_client_list_channel_private_keys and
5343 silc_client_free_channel_private_keys
5345 Affected file lib/silcclient/client_channel.c.
5347 * Added the support for the private keys in the channel message
5348 sending and encryption and in the message reception and
5349 decryption. Affected funtions are
5350 silc_client_send_channel_message and silc_client_channel_message.
5352 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Added SKE's key verify callback to the client library's
5355 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5357 * Removed the statement that server (or router) must send USERS
5358 command reply when joining to the channel so that the client
5359 knows who are on the channel. Instead, the client list and
5360 client's mode list is now sent in the JOIN command reply to the
5361 client who joined channel. This is better solution.
5363 * Added function silc_server_get_users_on_channel and function
5364 silc_server_save_users_on_channel to the silcd/server.[ch].
5366 * Removed function silc_server_command_send_users from the
5369 * Do not show topic on the client library anymore. The topic is
5370 sent in the command reply notify to the application and the
5371 application must show the topic now.
5373 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Added client searching by nickname hash into the IDENTIFY and
5376 WHOIS commands in the server as they were clearly missing from
5377 them. Affected file is silcd/command.c.
5379 * Fixed a bug in private message receiving in the client library.
5380 The remote ID was freed and it wasn't supposed, now it is
5383 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Minor fix to the channel payload; allocate the data area, as it
5386 needs to be of specific length.
5388 * If the key agreement port is zero then the operating
5389 system will define the bound port. Affected files are
5390 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5392 * Added new function silc_channel_payload_decrypt into the file
5393 lib/silccore/silcchannel.[ch].
5395 * Moved the channel message etc, check from silc_packet_decrypt
5396 to applications. The library calls now a generic
5397 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5398 when the packet is either normal or special. This was done to
5399 allow more wide range of checking that was not allowed when
5400 the code was in library. Now applications can do virtually any
5401 checks to the packet and return to the library the decision how
5402 the packet should be processed. Affected files are
5403 lib/silccore/silcpacket.[ch].
5405 Added silc_server_packet_decrypt_check to the server and
5406 silc_client_packet_decrypt_check to the client library.
5408 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5409 to send with specified source and destination information.
5411 * Channel message delivery between routers was broken after the
5412 channel key distribution was fixed earlier. The channel key
5413 was used be to distributed to other routers as well which is not
5414 allowed by the protocol. Now this is fixed and channel keys
5415 really are cell specific and the channel message delivery between
5416 routers comply with the protocol specification.
5418 * Fixed various commands in server to check also the global list
5419 for the channel entry and not just the local list. The affected
5420 file silcd/command.c.
5422 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added assert()s to buffer formatting and unformatting routines
5425 to assert (if --enable-debug) when error occurs. Affected
5426 file: lib/silcutil/silcbuffmt.c.
5428 * Changed to auto-reconnect to check whether the remote host is
5429 router and register the re-connect timeout if it is. It used
5430 to check that whether we are normal server, but router must do
5431 auto-reconnect with another router as well. Affected file
5434 * Removed the [<key len>] option from CMODE command as the cipher
5435 name decides the key length, nowadays. See the defined ciphers
5436 from the protocol specification.
5438 * Added [<hmac>] option to the CMODE command to define the HMAC
5439 for the channel. Added SILC_CMODE_HMAC channel mode.
5441 * Added [<hmac>] option for the JOIN command so that user can
5442 select which HMAC is used to compute the MACs of the channel
5445 * Added Hmac field to the Channel Message Payload. The integrity
5446 of plaintext channel messages are now protected by computing
5447 MAC of the message and attaching the MAC to the payload. The
5448 MAC is encrypted. Now, it is clear that this causes some
5449 overhead to the size of the packet but rationale for this is that
5450 now the receiver can verify whether the channel message decrypted
5451 correctly and also when private keys are set for the channel the
5452 receiver can decrypt the packet with several keys and check from
5453 the MAC which key decrypted the message correctly.
5455 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5456 lib/silccrypt/silccipher.[ch].
5458 * Added silc_hash_len to return the digest length into the
5459 lib/silcrypt/silchash.[ch].
5461 * Rewrote parts of Silc Channel Payload interface in the
5462 lib/silccore/silcchannel.[ch]. The encode function now also
5463 encrypts the packet and parse function decrypts it.
5465 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Fixed a minor formatting bug in the SKE's key material processing.
5468 It actually might have processed the keys wrong way resulting
5471 * Redefined the mandatory HMAC algorithms and added new algorithms.
5472 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5473 and hmac-md5 truncated to 96 bits. The mandatory is now
5474 hmac-sha1-96. Rest are optional (including the one that used
5475 to be mandatory). Rationale for this is that the truncated HMAC
5476 length is sufficient from security point of view and can actually
5477 make the attack against the HMAC harder. Also, the truncated
5478 HMAC causes less overhead to the packets. See the RFC2104 for
5481 * Added new [hmac] configuration section. The SKE used to use
5482 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5483 is of course wrong. The official names that must be proposed in
5484 the SKE are the ones defined in the protocol specification
5485 (hmac-sha1-96 for example). The user can configure any hmac
5486 using any hash function configured in the [hash] section. At
5487 least, the mandatory must be configured.
5489 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5491 * Added HMAC list to the SKE proposal list. It has now both
5492 hash algorithm list and HMAC list. This makes the protocol
5493 incompatible with previous versions. The SKE now seems to work
5494 the way it is supposed to work, for the first time actually.
5496 * Defined plain Hash algorithms to the protocol specification.
5499 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Implemented support for key agreement packets into the server.
5502 Added functions silc_server_key_agreement and
5503 silc_server_send_key_agreement. Other than these functions,
5504 server has nothing to do with this packet.
5506 * Added support for private message key packets into the server.
5507 Added functions silc_server_private_message_key and
5508 silc_server_send_private_message_key.
5512 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5513 called in the protocol's final callback instead in the END
5514 protocol state. This makes a little more sense and in the same
5515 time in client we can use the same protocol routines for normal
5516 key exchange and to key agreement packet handling as well.
5518 * Added to both client's and server's KE protocol context the
5519 SilcSKEKeyMaterial pointer to save the key material. We will
5520 bring the key material to the protocol's final callback by doing
5521 this. The final callback must free the key material.
5523 * Added SKE's packet_send callback into client's KE protocol
5524 context so that the caller can choose what packet sending function
5525 is used. This way we can use different packet sending when
5526 doing normal SKE when doing key agreement packet handling (in
5527 the key agreement packet handling we do not want to encrypt
5530 * Implemented the responder side of the key agreement routines
5531 in the client. The client can now bind to specified port and
5532 accept incoming key negotiation. The key material is passed
5533 to the application after the protocol is over.
5535 * Implemented the processing of incoming Key Agreement packet
5536 in the client. Added function silc_client_key_agreement to
5539 * Implemented the intiator side of the key agreement routines
5540 in the client. The client can now initiate key agreement with
5541 another remote client. The key material is passed to the
5542 application after the protocol is over.
5544 * Created client_keyagr.c to include all the key agreement
5547 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5548 SILC_TASK_CALLBACK except that it is not static.
5550 * Created client_notify.c and moved the Notify packet handling
5551 from the client.[ch] into that file.
5553 * Created client_prvmsg.c and moved all private message and
5554 private message key routines from the client.[ch] into that file.
5556 * Create client_channel.c and moved all channel message and
5557 channel private key routines from the client.[ch] into that file.
5559 * Changed silc_client_get_client_by_id_resolve to resolve with
5560 WHOIS command instead of IDENTIFY command, in the file
5561 lib/silclient/idlist.c.
5563 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Implemented the SKE's responder side to the Client library.
5567 * When FAILURE is received to the protocol do not trust it
5568 blindly. Register a timeout to wait whether the remote closes
5569 the connection as it should do it, only after that process the
5570 actual failure. This was changed to both client and server.
5572 * Added client_internal.h to include some of the structures
5573 there instead of client.h in lib/silcclient/.
5575 * Added function silc_task_unregister_by_callback to unregister
5576 timeouts by the callback function.
5578 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Some "Incomplete WHOIS info" errors has been appearing on the
5581 log files. Took away the entry->userinfo check from WHOIS
5582 reply sending. The entry->userinfo is now " " if client did not
5583 provide one. I thought this was fixed earlier but something
5584 is wrong still. Let's see if the error still appears.
5586 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Fixed a minor bug in the login when the channel key is
5589 re-generated in the server. It used to generate the key in
5590 wrong order and thus caused problems in the channel traffic.
5592 * Fixed a minor bug in channel key distsribution after
5593 KICK command. The key was not sent to the router even though
5596 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added silc_ske_process_key_material_data as generic routine
5599 to process any key material as the SILC protocol dictates. The
5600 function is used by the actual SKE library but can be used by
5601 applications as well. This relates to the private message keys
5602 and the channel private keys since they must be processed the
5603 same way the normal SILC session keys. The protocol dictates
5604 this. Affected files: lib/silcske/silcske.[ch].
5606 Added also silc_ske_free_key_material to free the
5607 SilcSKEKeyMaterial structure.
5609 * Defined silc_cipher_set_key function to set the key for
5610 cipher without using the object's method function. The affected
5611 files: lib/silccrypt/silccipher.[ch].
5613 * Implemented silc silc_client_add_private_message_key,
5614 silc_client_add_private_message_key_ske,
5615 silc_client_del_private_message_key,
5616 silc_client_list_private_message_keys and
5617 silc_client_free_private_message_keys functions in the
5620 Added functions silc_client_send_private_message_key to send
5621 the Private Message Key payload and silc_client_private_message_key
5622 to handle incoming Private Message Key payload.
5624 * Added Cipher field to the Private Message Key payload to set
5625 the cipher to be used. If ignored, the default cipher defined
5626 in the SILC protocol (aes-256-cbc) is used.
5628 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Removed lib/silcclient/ops.h file.
5632 Redefined parts of the SILC Client Library API. Created new
5633 file silcapi.h that deprecates the ops.h file and defines the
5634 published Client Library API. Defined also private message key
5635 API and channel private key API into the file.
5637 This is the file that the application must include from the
5638 SILC Client Library. Other files need not be included by
5639 the application anymore.
5641 * Added new key_agreement client operation callback and also
5642 defined the Key Agreement library API for the application.
5644 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5647 is used by clients to request key negotiation between another
5648 client in the SILC network. If the negotiation is started it
5649 is performed using the SKE protocol. The result of the
5650 negotiation, the secret key material, can be used for example
5651 as private message key.
5653 Implemented the Key Agreement payload into the files
5654 lib/silccore/silauth.[ch].
5656 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Redefined ciphers for the SILC protocol. Added some new ciphers
5659 and defined the key lengths for the algorithms. Changed the
5660 code accordingly. The default key length is now 256 bits.
5662 * Fixed SKE key distribution function silc_ske_process_key_material
5663 when the key length is more than 128 bits. The default key
5664 length in SILC is now 256 bits.
5666 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5667 to indicate unsupported algorithm.
5669 * Renamed rijndael.c to aes.c and all functions as well.
5671 * Fixed a long standing channel key setting bug in client library.
5672 Weird that it has never surfaced before.
5674 * Fixed bug in channel deletion. If the entire channel is removed
5675 then it must also delete the references of the channel entry
5676 from the client's channel list as the client's channel entry and
5677 the channel's client entry share same memory.
5679 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Implemented CONNECT and SHUTDOWN commands in the client.
5683 * Implemented CLOSE command to the client.
5685 * Added the function silc_idlist_find_server_by_name into the
5686 files silcd/idlist.[ch].
5688 Added the function silc_idlist_find_server_by_conn into the
5689 files silcd/idlist.[ch].
5691 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * DIE command was renamed to SHUTDOWN. Updated the both code
5696 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5697 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5699 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5702 * Added function silc_server_create_connection function to create
5703 connection to remote router. My server implementation actually
5704 does not allow router to connect to normal server (it expects
5705 that normal server always initiates the connection to the router)
5706 so the CONNECT command is only good for connecting to another
5709 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5712 or some other client was kicked from the channel.
5714 Implemented the handling of the notify type to both client
5717 Implemented silc_server_send_notify_kicked to send the KICKED
5718 notify. It is used to send it to the server's primary router.
5720 * Implemented the KICK command into server and client.
5722 * Added `query' argument to the silc_idlist_get_client function
5723 to indicate whether to query the client from server or not if
5726 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5727 to indicate that the client is not channel founder.
5731 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Removed the rng context from SilcPacketContext structure and
5734 changed that the packet routine uses the Global RNG API.
5736 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Added support for quit message that client can "leave" on the
5739 channel when it quits the SILC. It is ditributed inside the
5740 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5742 Added silc_server_free_client_data that will take the
5743 signoff message as argument.
5745 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5747 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Updated parts of the protocol specification to keep it up
5752 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5755 payloads in one packet.
5757 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5758 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5759 use now the new List flag.
5761 * Also deprecated the following packet types: REPLACE_ID,
5762 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5764 * Added list support for Notify packet in server.
5766 * Added silc_server_send_notify_channel_change to send the
5767 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5768 the silc_server_send_replace_id.
5770 * Added silc_server_send_notify_nick_change to send the
5771 NICK_CHANGE notify type. Deprecates the function
5772 silc_server_send_replace_id.
5774 * Added silc_server_send_notify_join to send the JOIN notify type.
5775 Deprecates the function silc_server_send_new_channel_user.
5777 * Added silc_server_send_notify_leave to send LEAVE notify type.
5778 Deprecates the function silc_server_send_remove_channel_user.
5780 * Added silc_server_send_notify_cmode and
5781 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5782 types. Deprecates the silc_server_send_set_mode function.
5784 * Added SERVER_SIGNOFF notify type to indicate that server has
5785 quit. This means that all clients on the channel from that
5786 server will drop. This can be also used when netsplit happens.
5788 Deprecated REMOVE_ID packet type since it is not needed anymore
5791 Added silc_server_send_notify_server_signoff to send the
5792 SERVER_SIGNOFF notify type. Deprecates the function
5793 silc_server_send_remove_id.
5795 Added also silc_server_send_notify_signoff to send the
5796 SIGNOFF notify type.
5798 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5799 SILC protocol from this day on. Changed the protocol
5800 specification as well.
5802 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5803 notify type. It is used between routers to notify about
5804 topic changes on a channel.
5806 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5809 * Partly updated the protocol specification to comply with the
5810 changes now made. It is still though a bit outdated.
5812 * The JOIN notify type now takes one extra argument <Channel ID>.
5813 The packet used to be destined to the channel but now the
5814 JOIN type may be sent as list thus it is impossible to
5815 destine it to any specific channel. By adding this argument
5816 it is again possible.
5818 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Added CREDITS file. The CHANGES and CREDITS file will appear
5821 in the distribution as well.
5823 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5826 types in the server's silcd/packet_receive.c.
5828 * Implemented CMODE and CUMODE to work in router environment.
5830 * Fixed minor encoding and decoding buglet from the
5831 lib/silccore/silcmode.c.
5833 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5836 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5838 * Changed all SilcConfigServer* and silc_config_server* to
5839 SilcServerConfig* and silc_server_config*, respectively.
5842 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Associated the ID (client or server ID) to the Authentication
5845 Payload to avoid any possibility of forging. Updated the
5846 protocol specification and the code accordingly.
5848 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * The RSA key length is now save to the RsaKey context in the
5851 key generation process in lib/silccrypt/rsa.c. The key length
5852 is now used to figure out the maximum size of the block allowed
5853 to be encrypted/signed.
5855 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5856 is equivalent to the silc_mp_mp2bin but does not allocate any
5859 * Changed silc_mp_mp2bin API to take length argument. If it is
5860 non-zero then the buffer is allocated that large. If zero, then
5861 the size is approximated using silc_mp_sizeinbase, which however
5864 * Created Global RNG API which is global RNG that application can
5865 initialize. After initializing, any routine anywhere in the
5866 code (including library) can use RNG without allocating a new
5867 RNG object. This was done to allow this sort of use of the
5868 RNG in code that has no chance to allocate RNG object. All
5869 applications currently allocate this and many routines in the
5870 library use this. Affected file lib/silccrypt/silcrng.[ch].
5872 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5873 it to use the Global RNG API.
5875 * Defined Authentication Payload into protocol specification that
5876 is used during SILC session to authenticate entities. It is
5877 used for example by client to authenticate itself to the server
5878 to obtain server operator privileges.
5880 Implemented this payload into the lib/silccore/silcauth.[ch].
5881 Implemented also routines for public key based authentication
5882 as the new protocol specification dictates.
5884 Moved definitions of different authentication methods from
5885 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5887 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5888 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5889 silc_pkcs_verify_with_hash functions into the file
5890 lib/silccrypt/silcpkcs.[ch].
5892 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * The client entry's userinfo pointer must be always valid.
5895 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5896 will fail since it requires the userinfo. Now, the userinfo
5897 is allocated as "" if actual userinfo does not exist. Actually,
5898 it must exist and it is totally Ok to drop client connections
5899 that does not announce the userinfo. However, we will make
5900 this workaround for now.
5902 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5903 to return the remote port by socket.
5905 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5908 SILC_SERVER_PENDING_EXEC and added an new macro
5909 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5910 data or when error occurs while processing the pending command.
5912 Added new argument `destructor' into silc_server_command_pending
5913 and to the SilcServerCommandPending object. This destructor is
5914 now called after calling the pending callback or if error occurs
5915 immediately. If error occurs the actual pending callback won't
5916 be called at all - only the destructor. The destructor may be
5917 NULL if destructor is not needed.
5919 All this applies for client library code as well. Similar
5920 changes were made there as well for the pending commands.
5922 In the client, the application must now allocate the
5923 SilcClientCommandContext with the silc_client_command_alloc
5926 * Added reference counter to the SilcServerCommandContext. Added
5927 function silc_server_command_alloc and silc_server_command_dup
5930 Same type of functions added to the client library for the same
5933 * Removed the cmd_ident from IDListData away since it is now
5934 global for all connections. It is the command identifier used
5935 in command sending and with pending commands. The affected file
5938 * Added reference counter to the SilcSocketConnection objecet to
5939 indicate the usage count of the object. The object won't be
5940 freed untill the reference counter hits zero. Currently only
5941 server uses this, and client ignores it. The client must be
5942 set to use this too later. The affected files are
5943 lib/silccore/silcsockconn.[ch]. Added also the function
5944 silc_socket_dup to increase the reference counter.
5946 This was mainly added because it is possible that the socket
5947 is removed underneath of pending command or other async
5948 operation. Now it won't be free'd and proper DISCONNECTING
5949 flags, etc. can be set to avoid sending data to connection that
5950 is not valid anymore.
5952 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5953 the connection. After that it sets SILC_SET_DISCONNECTED.
5954 It is, however, possible that the socket data is not still freed.
5955 The silc_server_packet_process now checks that data is not
5956 read or written to connection that is DISCONNECTED. The socket
5957 get's freed when the reference counter hits zero.
5959 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Changed the client operation API: channel_message operation's
5962 `sender' is now the client entry of the sender, not the nickname
5963 and the `channel' is the channel entry, not the channel name.
5965 In the private_message operation the `sender' is now also the
5966 client entry of the sender not the nickname.
5968 Affected file is lib/silcclient/ops.h and all applications
5969 using the client operations.
5971 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Moved the calling of ops->connect() from connect_to_server_final
5974 into receive_new_id functin since that is the point when the
5975 client is actually allowed to send traffic to network. The
5976 affected file is lib/silcclient/client.c.
5978 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5981 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5982 (if needs broadcasting) instead of broadcasting the packets one
5983 by one which would make a burst in the network traffic.
5985 * Added `broadcast' argument to the functions in silcd/server.[ch]
5986 silc_server_create_new_channel[_with_id] to indicate whether
5987 to send New Channel packet to primary router.
5989 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Added new function into the silcd/server.[ch] files:
5992 silc_server_create_new_channel_with_id to create new channel with
5993 already existing Channel ID.
5995 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5996 lib/silccore/silcpacket.h. This packet is used t send list of
5997 Set Mode payloads inside one packet. Server uses this to set
5998 the modes for the channels and clients on those channels, that it
5999 announced to the router when it connected to it. The protocol
6000 specification has been updated accordingly.
6002 * The silc_server_new_channel did not handle the packet coming
6003 from normal server as it normally does not send that. However,
6004 when it announces its channels it does send it. Implemented
6005 the support for that.
6007 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6008 into the file lib/silccore/id.h.
6010 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6012 * Fixed memory leaks in the functions silc_idlist_del_client,
6013 silc_idlist_del_channel and silc_idlist_del_server in the file
6014 silcd/idlist.c. All of those leaked like a sieve.
6016 * Fixed some small memory leaks in the client's function
6017 silc_client_notify_by_server.
6019 * Added functions into silcd/server.c: silc_server_announce_clients,
6020 silc_server_announce_channels and silc_server_announce_server.
6021 These functions are used by normal and router server to announce
6022 to its primary router about clients, channels and servers (when
6023 router) that we own. This is done after we've connected to the
6026 These functions effectively implements the following packet types:
6027 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6028 and SILC_PACKET_NEW_ID_LIST.
6030 * Added new functions into the silcd/packet_receive.[ch]:
6031 silc_server_new_id_list, silc_server_new_channel_list and
6032 silc_server_new_channel_user_list to handle the incoming
6033 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6035 * Added support of changing Channel ID in the function
6036 silc_server_replace_id. If the server that announces a channel
6037 to the router already exists in the router (with same name but
6038 with different Channel ID), router is responsible to send
6039 Replace ID packet to the server and force the server to change
6040 the Channel ID to the one router has.
6042 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6043 client that the Channel ID has been changed by the router. The
6044 normal server sends this to the client. Client must start using
6045 the new Channel ID as the channel's ID.
6047 Implemented handling of this new type into lib/silcclient/client.c
6048 into the function silc_client_notify_by_server.
6050 * Added new function silc_idlist_replace_channel_id into the files
6051 silcd/idlist.[ch] to replace the Channel ID.
6053 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Call silc_server_command_identify_check always when processing
6056 the IDENTIFY command in silcd/command.c
6058 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6061 send keepalive packets. The packet can be sent by clients,
6062 servers and routers.
6064 Added function silc_socket_set_heartbeat into the file
6065 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6066 If not set, the heartbeat is not performed. The actual
6067 heartbeat is implemented in the low level socket connection
6068 library. However, application is responsible of actually
6071 Added silc_server_send_heartbeat to send the actual heartbeat
6072 packet into silcd/packet_send.[ch]. Server now performs
6073 keepalive with all connections.
6075 * Added silc_task_get_first function into lib/silcutil/silctask.c
6076 to return the timeout task with shortest timeout. There was a bug
6077 in task unregistration that caused problems. TODO has been
6078 updated to include that task system must be rewritten.
6080 * The client library will now resolve the client information when
6081 receiving JOIN notify from server for client that we know but
6082 have incomplete information.
6084 * Rewrote parts of silc_server_remove_from_channels and
6085 silc_server_remove_from_one_channel as they did not remove the
6086 channel in some circumstances even though they should've.
6088 * Encryption problem encountered in server:
6090 The LEAVE command used to send the Channel Key packet to the
6091 router immediately after generating it. However, the code
6092 had earlier sent Remove Channel user packet but not immediately,
6093 ie. it was put to queue. The order of packets in the router
6094 was that Channel Key packet was first and Remove Channel User
6095 packet was second, even though they were encrypted in the
6096 reverse order. For this reason, MAC check failed. Now, this
6097 is fixed by not sending the Channel Key packet immediately but
6098 putting it to queue. However, this is more fundamental problem:
6099 packets that are in queue should actually not be encrypted
6100 because packets that are sent immediately gets encrypted
6101 actually with wrong IV (and thus MAC check fails). So, packets
6102 that are in queue should be encrypted when they are sent to
6103 the wire and not when they put to the queue.
6105 However, the problem is that the current system has not been
6106 designed to work that way. Instead, the packet is encrypted
6107 as soon as possible and left to the queue. The queue is then
6108 just purged into wire. There won't be any fixes for this
6109 any time soon. So, the current semantic for packet sending
6112 o If you send packet to remote host and do not force the send
6113 (the packet will be in queue) then all subsequent packets to the
6114 same remote host must also be put to the queue. Only after the
6115 queue has been purged is it safe again to force the packet
6118 o If you send all packets immediately then it safe to send
6119 any of subsequent packets through the queue, however, after
6120 the first packet is put to queue then any subsequent packets
6121 must also be put to the queue.
6123 Follow these rules and everything works fine.
6125 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Added new function silc_server_remove_clients_by_server to
6128 remove all client entries from ID list when the server connection
6129 is lost. In this case it is also important to invalidate all
6130 client entires as they hold the invalid server entry. This
6131 fixes fatal bug when server has lost connection and will reconnect
6134 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Made some sanity checks to silc_server_daemonise like to check
6137 whether the requested user and group actually exists.
6139 * Added sanity check to SKE's silc_ske_responder_finish to check
6140 that the public and private key actually is valid.
6142 * Invalidate the client's nickname when receiving Replace ID
6143 packet and the Client ID is being replaced. This means that the
6144 server will query the nickname if someone needs it (client)
6147 * Sort the ID Cache in client library when the ID Cache data
6148 has changed (needs sorting).
6150 * Do not allow for SILC client to create several connections to
6151 several servers. The client does not support windows right now
6152 and generating multiple connections causes weird behaviour.
6154 Irssi-silc client does support windows and can handle several
6155 connections without problems, see: www.irssi.org and SILC plugin.
6157 * Fixed some places where client was added to the IDList. The
6158 rule of thumb is following (in order to get everything right):
6159 If the client is directly connected local client then the
6160 `connection' argument must be set and `router' argument must be
6161 NULL to silc_idlist_add_client function. If the client is not
6162 directly connected client then the `router' argument must
6163 bet set and the `connection' argument must be NULL to the
6164 silc_idlist_add_client function.
6166 * The funtion silc_server_packet_send_local_channel actually did
6167 not check whether the client was locally connected or not. It
6168 does that now. Fixed a bug related to LEAVE command.
6170 * Fixed Remove Channel User payload parsing bug in server's
6171 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6173 * The server's silc_server_save_channel_key now checks also the
6174 global ID list for the channel as it might not be in the local
6175 list. Fixed a bug related to LEAVE command.
6177 * Is this the end of the [<unknown>] buglet that has been lurking
6178 around for a long time? A little for loop fix in server's
6179 silc_server_command_whois_parse that is used by both IDENTIFY
6180 and WHOIS command. At least, this was a clear bug and a cause
6181 of one type of [<unknown>] buglet.
6183 * WHOIS and IDENTIFY commands call the function
6184 silc_server_command_[whois/identify]_check function even if
6185 we are not router server.
6187 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Added --with-gmp configuration option. If set the GMP
6190 is always compiled in the SILC source tree. If not set then
6191 it is checked whether the system has the GMP3 installed. If
6192 it has then the GMP won't be compiled (the system's headers
6193 and library is used), if it doesn't have it then the GMP is
6194 compiled in the SILC source tree.
6196 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6198 * Changed RSA private exponent generation to what PKCS #1
6199 suggests. We try to find the smallest possible d by doing
6200 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6201 not security fix but optimization.
6203 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Added new config entry [Identity] to fork the server and run
6206 it as specific user and group. A patch from Bostik.
6208 * Imported Dotconf configuration library into lib/dotconf.
6209 This will be used to create the SILC configuration files later.
6210 It will appear in the distsribution after this commit.
6212 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * A big code auditing weekend happening. Auditing code for
6215 obvious mistakes, bugs and errors. Also, removing any code
6218 Removed files for being obsolete:
6220 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6221 inline in the file lib/silcutil/silcbuffer.h)
6223 o lib/silcutil/silcbufutil.c (the header has inline versions)
6225 Changed code to fix possible error conditions:
6227 o The buffer formatting routines now check that the destination
6228 buffer really has enough space to add the data. This applies for
6229 both buffer formatting and unformatting
6230 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6231 unformatting was changed to accomodate following rules:
6232 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6233 sent to the function while XXX_*STRING will not allocate or copy
6234 the data into the buffer. Instead it sets the pointer from the
6235 buffer into the pointer sent as argument (XXX_*STRING used to
6236 require that the pointer must be allocated already). This change
6237 makes this whole thing a bit more consistent and more optimized
6238 (note that the data returned in the unformatting with XXX_*STRING
6239 must not be freed now). The routines return now -1 on error.
6241 o Tried to find all code that use buffer_format and buffer_unformat
6242 and added return value checking to prevent formatting and
6243 especially unformatting errors and possible subsequent fatal
6246 o Changed ske->x and ske->KEY to mallocated pointers in
6247 lib/silcske/silcske.h. Fixed possible data and memory leak.
6249 o Added return value checking to all *_parse* functions. Fixed
6250 many memory leaks as well.
6252 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6253 so that buffer overflows would not happen. All code now also
6254 checks the return value as it can fail.
6256 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * Added reconnection support to server if the normal server looses
6259 its connection to the router (for example if router is rebooted).
6260 The server performs normal reconnection strategy implemented
6261 to the server. Affected file silcd/server.c.
6263 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Added new packet type SILC_PACKET_SET_MODE that is used to
6266 distribute the information about changed modes (for clients,
6267 channels and clients channel modes) to all routers in the
6268 network. Updated the protocol specification accordingly.
6270 Added functions into silcd/packet_send.c and
6271 silcd/packet_receive.c: silc_server_send_set_mode,
6272 silc_server_set_mode.
6274 Added new files silcmode.[ch] into lib/silccore that implements
6275 the encoding and decoding of Set Mode Payload. Added new type
6276 SilcSetModePayload. Moved the definitions of different modes
6277 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6279 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Oops, a little mistake in server's connection authentication
6282 protocol. The protocol is not ended with FAILURE but with
6283 SUCCESS if the authentication is Ok. :) Affected file is
6286 * Implemented NICK_CHANGE notify handling in server in the file
6287 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6288 the local clients on the channel. After the changing nickname
6289 in router environment snhould work and the [<unknown>] nickname
6290 should appear no more.
6292 The silc_server_replace_id function that receives the Replace ID
6293 payload now sends the NICK_CHANGE notify type also in the file
6294 silcd/packet_receive.c
6296 * Changed WHOIS and IDENTIFY command to support the maximum amount
6297 of arguments defined in protocol specs (3328 arguments). This
6298 fixed a bug that caused problems when there were more than three
6301 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Added extra parameter, command identifier, to the
6304 silc_client_send_command so that explicit command identifier
6307 Changed that ID list routines uses specific command identifier
6308 when sending WHOIS/IDENTIFY requests to the server so that they
6309 can be identified when the reply comes back.
6311 Affected files lib/silcclient/command.[ch],
6312 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6314 * Added `sender' argument to silc_server_packet_send_to_channel
6315 to indicaet the sender who originally sent the packet to us
6316 that we are now re-sending. Ignored if NULL. Affected file
6317 silcd/packet_send.[ch].
6319 * Added some server statistics support in silcd/server_internal.h
6320 SilcServerStatistics structure and around the server code. Also
6321 send some nice statistics information when client is connecting
6324 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Fixed channel ID decoding in server's JOIN command reply in
6327 silcd/command_reply.c
6329 * Fixed braodcasting of replace ID payload to not to send it if
6330 we are standalone server in silcd/packet_receive.c.
6332 * Fixed all channel message sending routines to not to send
6333 packets to clients that has router set, since they are routed
6334 separately in the same function earlier. Affects file
6335 silcd/packet_send.c and all channel packet sending functions.
6337 * In USERS reply, res_argv[i] are not allocated, the table
6338 is allocated. Thus changed that free the table, not its
6341 * In server's whois_check and identify_check if the client is
6342 locally connected do not send any WHOIS commands - they are not
6345 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Fixed some minor bugs in client when sending WHOIS command. The
6348 arguments was in wrong order.
6350 * Removed statis function add_to_channel from server in
6351 silcd/command.c that was previously used with the joining but
6354 * Tested USERS command in router environment successfully with two
6355 routers, two servers and two clients.
6357 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * Reorganized the USERS command and command reply in client library
6360 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6361 When the command is given by user we register a pending command
6362 callback that will reprocess the command after the reply has been
6363 received from the server. When reprocessing the packet we then
6364 display the information. Thus, the USERS information is displayed
6365 now in the command callback instead of in the command reply
6366 callback. The processing of the command is same as previously
6367 when server has sent the command reply in the JOINing process.
6369 * Added to USERS command in silcd/command_reply.c to join the client,
6370 we didn't use to know about, to the channel after we've created
6371 a client entry for it. Also, for clienet we did know already still
6372 check whether it is on the channel or not and add it if not.
6374 * Removed silc_server_command_join_notify as the function and its
6377 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * Changed the client's pending command handling to the same as the
6380 server's pending command handling. It is also now possible to
6381 execute command reply functions from other command reply
6382 function as the function callbacks for commands and command
6383 replies are one and same. The pending commands are not static
6384 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6385 in client connection context. Thus, pending commands are server
6386 connection specific as it is convenient.
6388 Changed the function silc_client_command_pending and
6389 silc_client_command_pending_del and added new function
6390 silc_client_command_pending_check. Removed the
6391 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6394 * Added cmd_ident, current command identifier, to the client
6395 connection context in lib/silcclient/client.h to keep track on
6396 command identifiers used in command sending. Client's command reply
6397 function handling now supports the mandatory command identifiers.
6399 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6400 funtions in client to fully support pending command callbacks.
6402 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6403 as one of the arguments to the application in the command reply
6406 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6407 before first releasing SILC but came back. Now it is removed again
6408 and should come back nomore. The FORWARDED flag was used only
6409 by the JOINing procedure by forwarding the command packet to router.
6410 Now, the JOINing procedure has been changed to more generic (due
6411 to various router environment issues) and FORWARDED is not needed
6412 anymore for anything. The protocol specification is yet to be
6415 Now, removed silc_server_packet_forward from server and the flag
6416 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6418 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Renamed NAMES command to USERS command. The NAMES was named that
6421 due to historical reasons. Now it is renamed. Also, rewrote
6422 parts of the USERS command. The nickname list is not sent anymore
6423 by the server. Only Client ID and mode lists are sent in the USERS
6424 command. Changed this also to the protocol specification.
6426 The client now resolves the names and stuff after it receives
6427 the USERS list from the server when joining to the channel.
6429 * WHOIS and IDENTIFY commands has been changed to support multiple
6430 Client ID's per command. One can now search for multiple users
6431 in the network by sending only one WHOIS or IDENTIFY command.
6432 Changed the code and the protocol specifications.
6434 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6435 uses silc_server_command_whois_parse to parse the request. */
6437 * If normal server, do not parse the WHOIS and IDENTIFY requests
6438 before sending it to the router. Saves some time.
6440 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6442 * Fixed JOIN command on client library. Wrong number of arguments
6443 used to crash the client.
6445 * Added silc_server_channel_has_global function to check whether
6446 channel has global users or not.
6448 * Added silc_server_channel_has_local function to check whether channel
6449 has locally connected clients on the channel.
6451 * The silc_server_remove_from_one_channel now checks whether the
6452 channel has global users or not after given client was removed from
6453 the channel. It also checks whether the channel has local clients
6454 on the channel anymore. If it does not have then the channel entry
6455 is removed as it is not needed anymore.
6457 * The silc_server_notify now checks on JOIN notify whether the joining
6458 client is one of locally connected or global. If it is global then
6459 the channel has now global users on the channel and that is marked
6460 to the channel entry. Also, it now saves the global client to
6461 global list who is joining and JOINs it to the channel. This is
6462 for normal server, that is.
6464 Changed silc_server_send_notify_on_channel,
6465 silc_server_packet_relay_to_channel and
6466 silc_server_packet_send_to_channel check if we are normal server
6467 and client has router set (ie. global client) do not send the
6468 message to that client, as it is already routed to our router.
6470 * Implemented LEAVE notify type handling in silc_server_notify
6473 * Tested LEAVE command in router environment successfully. Tested
6474 with two routers, two servers and two clients.
6478 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6480 * Implemented SIGNOFF notify type handling in silc_server_notify
6483 * silc_server_remove_id now removes the client entry from all channels
6484 it has joined and thusly sends SIGNOFF notify type.
6486 * Rewrote the NAMES list generation in server by removing two excess
6487 loops. The lists are created now inside one loop.
6489 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * silc_server_remove_channel_user checks now also global list
6492 for channel and client.
6494 * silc_server_new_channel_user checks now both local and global
6495 list for channel and client. Fixed a bug in client id decoding.
6496 Used to decode wrong buffer.
6498 * silc_server_channel_message checks now both local and global
6499 list for channel entry.
6501 * Tested channel joining (hence JOIN) in router environment
6502 successfully. Tested with two routers, two servers and two
6505 * Tested channel message sending in router environment successfully.
6507 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6509 * Added silc_server_save_channel_key into server.[ch] to save the
6510 received channel key in Channel Key payload processing. It is
6511 also used in JOIN command reply handling.
6513 Equivalent function silc_client_save_channel_key added into
6514 client.[ch] into client library.
6516 * Changed JOIN command reply to send information whether the channel
6517 was created or not (is existing already) and the channel key
6518 payload. Changed protocol specs accordingly.
6520 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6521 the request was sent by ID and not by nickname. Crashed on
6524 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6526 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6527 now correctly save the received data.
6529 * silc_server_free_sock_user_data now notifies routers in the
6530 network about entities leaving the network.
6532 At the same time implemented functions silc_server_remove_id
6533 and silc_server_send_remove_id to receive and send REMOVE_ID
6534 packets. The packet is used to notify routers in the network
6535 about leaving entities. The ID removed will become invalid in
6538 * Added function silc_idlist_del_server into server. Removes and
6539 free's server entry from ID list.
6541 * silc_server_private_message function now checks, if we are router,
6542 that the destination ID really is valid ID, naturally.
6544 * In router when NEW_ID packet is received (for new client) the
6545 hash of the Client ID is saved in the ID Cache but the
6546 client->nickname is set to NULL, instead of putting the hash
6549 IDENTIFY command now also checks that client->nickname must be
6550 valid. If it is not if will request the data from the server who
6551 owns the client. Added new function
6552 silc_server_command_identify_check.
6554 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6555 to set the command to already allocated Command Payload.
6557 * Tested private message sending in router environment with two
6558 routers, two servers and two clients. Fixed minor bugs and now
6561 * Fixed segfault from client's NAMES command. Used to crash if
6564 * Forwarded packets must not be routed even if it is not destined
6565 to the receiver. Changed server code comply with this.
6567 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Added `require_reverse_mapping' boolean value to ServerParams
6570 structure. If TRUE (not default) the server will require that
6571 the connecting host has fully qualified domain name.
6573 If the reverse mapping is not required and hostname could not be
6574 found the IP address is used as hostname.
6576 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Implemented version string checking to both client and server.
6579 The check is incomplete currently due to the abnormal version
6580 strings used in development version of SILC.
6582 * Changed all command functions in server to use the new
6585 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6587 * Changed char *data to unsigned char *data in ID Cache system to
6588 support binary data as ID Cache data. Changed code to support
6589 binary data in lib/silccore/idcache.c.
6591 * Renamed silc_server_packet_relay_command_reply to
6592 silc_server_command_reply as it is normal packet receiving
6593 function. Rewrote the function to accept command replys for
6594 servers and not only for clients.
6596 * Mark remote router always as registered server if we are connecting
6597 to it. Otherwise, commands sent by the router to us are ignored.
6599 * All ID List find routines now returns the ID Cache Entry pointer
6600 as well if requested.
6602 * WHOIS command works now in router environment, tested with two
6603 routers, two servers and two clients.
6605 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6606 in router environment (as it is almost equivalent to WHOIS) but
6607 hasn't been tested thoroughly. Added new functions:
6609 silc_server_command_identify_parse
6610 silc_server_command_identify_send_reply
6611 silc_server_command_identify_from_client
6612 silc_server_command_identify_from_server
6614 * Disabled route cache adding because adding two different ID's with
6615 same IP replaces the old cache entry thus giving wrong route.
6616 The entry->router->connection is always the fastest route anyway
6617 so route cache may not be needed. Of course, new routes maybe
6618 established after receiving the ID when the entry->router->connection
6619 might not be anymore the most optimal.
6621 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Add route cache for received ID for fast routing.
6625 * Added silc_server_packet_route to route received packet on router
6626 that is not destined to us.
6628 * Renamed silc_server_get_route to silc_server_route_get.
6630 * Added id_string and id_string_len fields into SilcServer to
6631 include encoded ServerID for fast comparing without excess
6632 encoding of the ID's.
6634 * Cleaned up WHOIS command on server side. Added following static
6637 silc_server_command_whois_parse
6638 silc_server_command_whois_check
6639 silc_server_command_whois_send_reply
6640 silc_server_command_whois_from_client
6641 silc_server_command_whois_from_server
6643 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6644 arguments in command replies. All command functions should be
6645 updated to use this macro.
6647 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Minor typo fixes on command reply handling on server.
6651 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Added silc_server_command_add_to_channel internal routine to add
6654 the client to the channel after router has created the channel and
6655 sent command reply to the server.
6657 * Added generic silc_server_send_command to send any command from
6660 * Use static buffer with ID rendering instead of duplicating data.
6662 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Fixed a channel user mode bug when joining to a channel server gave
6665 everybody channel founder rights, oops.
6667 * We mark ourselves as the router of the incoming server connection
6668 if we are router ourselves. This way we can check in some packet
6669 sending functions whether it is locally connected server. For
6670 incoming router connections we put NULL.
6672 * For router sending packets locally means now always sending the
6673 packet cell wide; to local clients and local servers. For normal
6674 server sending packet locally means sending it to only local
6677 * Fixed the JOIN command to really work in router environment. If the
6678 channel is created it is always created by the router. Router is
6679 also responsible of making the initial joining to the channel,
6680 sending JOIN notify to the sending server and distributing
6681 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6682 does not exist server doesn't do anything else but forward the
6683 command to the router which performs everything.
6685 * Added silc_server_send_channel_key function to send the Channel Key
6688 * Added silc_server_create_channel_key to create new channel key. The
6689 channel key is now re-generated everytime someone joins or leaves
6690 a channel, as protocol dictates. Note: channel->key_len is the
6693 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6695 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6696 packet_receive.[ch] to separate packet sending and receiving
6697 routines. The server.[ch] now includes everything else including
6698 actual packet processing (writing and reading data) and other
6701 Renamed silc_server_private_message_send_internal to
6702 silc_server_send_private_message. The routine is still though
6703 used only to relay private messages as server does not send
6704 private messages itself.
6706 Renamed silc_server_new_channel to silc_server_create_new_channel
6707 and added new function sicl_server_new_channel that handles the
6708 incoming New Channel packet. Added also new sending function
6709 silc_server_send_new_channel to send New Channel Payload.
6711 * Added new function silc_server_notify to process incoming notify
6712 packet to the server/router. Server may then relay the notify
6713 to clients if needed.
6715 * Added new function silc_server_new_channel_user to process incoming
6716 New Channel User packet. Router will redistribute the packet and
6717 send JOIN notify to its local clients and locally connected servers
6718 if needed. Normal server will send JOIN notify to its local client
6719 on same channel when received this packet. Added also corresponding
6720 sending function silc_server_send_new_channel_user to sent the
6723 * Added boolean route argument to send_notif_to_channel and
6724 packet_send_to_channel functions to attempt to route the packet
6725 if it is TRUE and send only locally if it is FALSE.
6727 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6729 * silc_server_replace_id now broadcasts the received replace ID
6730 packet if it is not broadcast packet already. The router must
6731 broadcast to inform other routers about changed ID.
6733 * Added backpointer to server's router into SilcServer context in
6734 silcd/server_internal.h.
6736 * Fixed silc_server_packet_broadcast to send correct broadcast
6739 * The channel key is now distributed to the local client as soon
6740 as it is received from the router (in router environment) so that
6741 no other packet may be sent for the channel until client has
6744 * silc_server_remove_channel_user now broadcasts the received
6745 Remove Channel User packet if it is not broadcast packet already.
6746 The router must broadcast to inform other routers about removed
6749 * Added users field into SilcPacketContext that is a reference count
6750 of the context. One can increase the reference count by calling
6751 silc_packet_context_dup which is now changed to just increase the
6752 reference count instead of duplicating the data. The reference
6753 count is decresed by calling silc_packet_context_free that will
6754 free the data after the reference count hits zero.
6756 For now on the packet context and everything allocated into it
6757 (including the raw packet from network) must be freed by calling
6758 the new silc_packet_context_free function. Added also new function
6759 silc_packet_context_alloc that must be used now to allocate the
6760 context. This also means that if a routine is asynchronous from
6761 silc_[client/server]_packet_parse_type the packet context must
6762 be duplicated by calling silc_packet_context_dup. Otherwise it
6763 gets free'd after silc_[client/server]_packet_parse_type returns.
6764 Also, one must remember that if packet is duplicated then its
6765 reference count must be decresed by calling the free function as
6766 many times as it was duplicated.
6768 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6769 from both client and server.
6771 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Made joining to a channel working in router environment.
6775 * Cleaned up JOIN command on server side and create function
6776 silc_server_command_join_channel internal routine to make the
6779 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Changed silc_command_pending list to SilcDList. Also, added
6782 `ident' field to SilcServerCommandPending structure to identify
6783 the reply and to call correct callback.
6785 Added silc_server_command_pending_check function to replace the
6786 corresnponding macro. The silc_command_pending list is not
6789 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6790 to set identifier to previously allocated Command Payload. It
6791 is used to set identifier for command when resending Command
6794 * Added silc_command_payload_encode_payload to encode Command
6795 Payload buffer from SilcCommandPayload structure.
6797 * Added silc_argument_payload_encode_payload to encode Argument
6798 payload buffer from SilcArgumentPayload structure.
6800 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Changed WHOIS command to support router connection on server side.
6803 The whois request is always sent to router unless the server is
6804 standalone server. After server has received the reply from the
6805 router will it send the reply to the client.
6807 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6808 broadcast received broadcast packet. The function is used only
6809 by router. The broadcast packet is always sent to the router's
6812 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6813 render given ID to printable string, for log files for example.
6815 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Made basic router to router connections working. At least they
6818 can now connect to each other but nothing really works the way
6819 they are supposed - yet.
6821 * Added new initiator token to RouterConnection configuration
6822 file in silcd/serverconfig.[ch]. It is used to tell whether we
6823 are the initiator to the remote router or whether we'll expect
6824 the other end to connect.
6826 * Moved registering of listener task to silc_server_init, hence
6827 the server starts listenning as soon as it is run, even if it
6828 does not have connections to other routers. Let's see how well
6831 * Changed default connection retry timeouts for more suitable in
6834 * Removed cipher and such arguments from silc_idlist_add_client
6835 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6836 Added new function silc_idlist_add_data to add the keys and stuff
6839 * Added SilcIDListData structure and added it to SilcClientEntry
6840 and SilcServerEntry as their first field in the structure. This
6841 way we can explicitly cast the ID entries to the SilcIDListData
6842 structure and get common data for the entries. In past, we had
6843 to first check what type of connection it is and then cast it to
6844 correct ID entry type. Now, we can directly cast the opaque
6845 pointer to the SilcIDListData (no matter what ID entry it actually
6846 is) and get the data needed.
6848 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6851 in some circumstances even if threre were timeout tasks, though not
6852 IO tasks, but tasks anyway. Now fixed.
6854 * Defined SilcServerConnection structure to hold connection specific
6855 stuff about directly connected servers and routers. The definition
6856 is currently in silcd/server_internal.h. I thought about having
6857 a bit more important role fro this struct but for now it is used
6858 only when connecting to other server (or router actually).
6860 * Added connecting retry support in server when connecting to
6861 router(s). The retry feature implement exponential backoff
6862 algorithm. Also, added SilcServerParams structure to hold default
6863 parameters for server. For now, it include these retry settings
6864 and are hard coded. After server is moded to be as Silc Server
6865 Library this structure will be more important.
6867 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Changed client librarys channel->clients table to SilcList and
6870 changed code accordingly.
6872 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Changed client's channel table to SilcList and changed code
6875 accordingly. Also changed SilcChannelClientEntry to include back-
6876 pointer to the channel so that client entry can use that structure
6877 as list as well and we have fast cross-reference to the channel.
6878 This change dramatically decreased the complexity of channel
6879 handling with client entry and vice versa (removed one extra
6880 loop when searching for channel entry from many functions).
6882 * Changed server->sim from table to SilcDList and changed code
6885 * NAMES command can now be used from user interface. It will show
6886 the user list on the channel, neatly.
6888 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6889 Code now saves realname of the user if it becomes available.
6891 * Renamed configure.in to configure.in.pre and made ./prepare
6892 script to automatically add correct version string to
6893 configure.in which it creates from configure.in.pre.
6895 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * NAMES command reply now shows users mode with the nickname when
6900 * Moved silc_client_ch[u]mode[_char] functions from
6901 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6902 place sucks, they are utility functions and should be in some
6905 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6907 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6910 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added TRQ (efficient deque and list library) into lib/trq. This is
6915 a very good list library that is currently used in the SILC. Defined
6916 SilcList API over the library because I didn't like the API very
6917 much. See lib/trq/silclist.h for the API and examples of how to
6918 use the API. Fixed various places in the code to use the new
6919 SilcList API. The SilcList is meant for lists that has a structure
6920 already defined as a list. It is not suitable to add just some
6921 context to the list (in TRQ, the context is the list actually).
6923 So, I defined SilcDList that can be used for the purpose where
6924 predefined list structure does not exit. This can be used as
6925 such list. Now some context just can be added to the SilcDList.
6926 Currently this list is not used in the SILC just yet, though there
6927 are a lot places where this can replace dynamically allocated
6928 tables and I will fix these places, later, to use SilcDList.
6929 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6930 and use TRQ internally).
6932 Also fixed some annoying warning messages that the original TRQ
6933 code generated. Also minor changes to TRQ's Makefile.in.
6935 * Added support for querying by Client ID to both WHOIS and
6936 IDENTIFY commands into server, as required by the protocol.
6938 * Removed method function pointers from SilcBuffer structure. They
6939 weren't used to anything and just increased the context size for
6940 no good reason. This change also made silc_buffer_alloc and
6941 silc_buffer_free functions inline functions.
6943 * Disabled command flooding detection support until it's fixed so
6944 that it accepts commands in but does not execute them more than once
6947 * Added silc_net_localhost(), to return local hostname, into
6948 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6949 that must be initialized before calling silc_client_init.
6951 * Added new function: silc_server_send_notify_on_channels to send
6952 notify messages to all channels client has joined. It is assured
6953 that the message is sent only once per client.
6955 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6956 lib/silcutil/silcutil.[ch] as silc_format function. The new
6957 function is generic and is used by server as well, not only by
6958 the logging routines.
6960 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6961 the provided version string was not acceptable. Added new function:
6962 silc_ske_check_version into lib/silcske/silcske.h. The function
6963 must be implemented by the application (client or server) and it
6964 does not reside in the SKE library. The function checks the version
6965 string remote end sent.
6967 * Added back pointers (to opaque context and to SilcSocketConnection)
6968 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6970 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6971 duplicate packet context structure.
6973 * Changed `notify' client operation to send same arguments as client
6974 receives from server except for ID's. ID's are mapped to correct
6975 ID entry and that is returned. Also, if channel entry is not sent
6976 by server but the notify is for channel the channel entry is sent
6977 to application (otherwise application doesn't know that it is for
6978 channel (library gets it from packet's Destination ID)).
6980 * Added silc_client_remove_from_channels into client library to
6981 remove a client from all channels it has joined to. Used when
6982 received SIGNOFF notify from server. Added also new function
6983 silc_client_replace_from_channels to replace old ID entry with
6984 new ID entry on all channels. Used when received NICK_CHANGE
6987 * Fixed ID Cache list handling in silc_idlist_get_client in
6988 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6989 to get (or query) client by ID.
6991 * Updated TODO list.
6993 * Added connection authentication status message defined by the
6994 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6995 support for these into the code in client and server side.
6997 * Added generic function silc_client_send_command to send any command
6998 with variable argument list. Application should use this function
6999 to send commands if the command functions provided by the library
7000 does not suite for the application's user interface needs.
7002 * Added new `failure' client operation. Application is notified about
7003 received failure packet if client is executing a protocol. In this
7004 case the protocol's execution has failed.
7006 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7007 is required by the protocol.
7009 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7010 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7013 * Added status flag to SilcSKE object to indicate realtime status
7014 of the SKE protocol.
7016 * Application receives now exactly same command reply arguments as
7017 the library receives from server. However, if ID is received the
7018 corresponding ID entry is returned to the application (eg. Client
7019 ID is mapped to correct SilcClientEntry entry and that is returned).
7020 Changed command_reply client operation due to this change.
7022 * Changed all ID's in commands and in command replys as ID Payloads.
7023 Change affected both client and server side codes.
7025 All ID's sent in SILC network (with execption of ID's in SILC
7026 Packet header) are sent in ID Payload to support variable length
7029 * Server now notifies nick changes and notifies all clients on
7030 the channels about the new nickname (about the new Client ID,
7033 * Implemented CMODE command to change channel modes. Supports all
7034 channel modes defined by the protocol specs except ban and invite
7035 lists. (Also, private channel key mode is supported but support for
7036 setting private channel key in client is missing, thus, this mode
7037 has no effect on client side (except that server requires that the
7038 client uses private channel key and normal channel traffic does not
7041 Also, invite mode works per se, but INVITE command does not work
7042 yet correctly, so you can set channel as invite only channel but
7043 inviting clients to the channel does not work (it is yet to be
7044 thought what's the best way to do it).
7046 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7047 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7048 Implemented CUMODE command to change user's mode on the channel.
7049 Supports all modes defined by the protocol specs.
7051 * Added NAMES command reply to return users modes on the channel.
7053 * Removed unnecessary and slow ciphers from lib/silccrypt.
7055 * Set SO_KEEPALIVE option to connection sockets by default.
7057 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7059 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7060 redefined the Notify Payload into protocol specs.
7062 * Added silc_id_payload_parse_id to get ID directly from raw
7065 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7068 accept searching by Client ID as well.
7070 * Added support for LEAVE and SIGNOFF notify types in client library.
7072 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7073 to parse ID Payload from raw data.
7075 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7077 * Added flags parameter into silc_ske_assemble_security_properties
7078 function in lib/silcske/silcske.[ch].
7080 * Changed notify client operation to fit better for notify messages
7081 sent by server. The notify payload received from server is now
7082 passed to the application (after parsing it to SilcNotifyPayload).
7083 It is application's responsibility to retrieve the arguments
7084 from the payload and show the message the way it wants. The message
7085 sent by server is implementation specific.
7087 * Changed public keys to comply with the protocol specification.
7088 Old public keys are not supported anymore and are not compatible.
7090 * Removed nickname from Channel Payload as the latest draft removed
7091 it. The client must resolve the nickname from the NAMES command
7092 reply received when it joined the channel.
7094 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7096 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Fixed some errors in protocol specification drafts.
7100 * Created lib/silccore/silcnotify.c to implement Notify Payload
7101 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7102 generic payloads described by protocol specifications. The file
7103 includes implementations for ID Payload and Argument Payload.
7105 * Changed Command Payload implementation to use the new Argument
7106 Payload. Changed command_xxxx_payload to command_payload_xxxx
7107 to comply with SILC coding conventions.
7109 * Added suppport for Argument Payload handling in Notify Payload
7110 implementation as protocol requires it. Added the new support
7111 into server and client lib as well.
7113 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Added support for multiple nicknames on same channel. [n] is
7116 added locally to the nickname if there are more than one same
7117 nicknames on the channel.
7119 * Server now sends all nicknames that matched WHOIS request.
7120 Client also shows the list received from server.
7122 * Added TOPIC command to client side. User can now set and show
7123 current topic on channel.
7125 * Added MOTD command to client and server. Also, server sends the
7126 motd when client connects to the server.
7128 * Changed version strings to comply ISO 8601.
7130 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Fixed protocol error handling in client library. It should now
7133 cope even if the SKE fails for some reason.
7135 * Made new protocol specification drafts for submitting to IETF.
7137 * Implemented TOPIC command to server in silcd/command.c.
7139 * Added two new notify types into lib/silccore/silcnotify.h:
7140 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7141 notify nickname change and topic setting/change on a channel.
7143 * API change of command_reply operation in client library. The
7144 application gets now the status type received from server as well.
7146 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7150 * Cras fixed and optimized the packet handling even further and
7151 it should work now. Minor change to the prototype of function
7152 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7154 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Added new function into lib/silcutil/silcschedule.[ch]:
7157 silc_schedule_with_fd to select() a specified fd. The function
7158 returns after timeout expires or data arrives or goes. The
7159 function is used by packet routines to wait that all data is
7160 received from network.
7162 * Fixed data reading from network in lib/silccore/silcpacket.c.
7163 The code now assures that all data is read from the fd and then
7164 continues packet processing. This was a bug fix since the code
7165 used to drop some data in some circumstances.
7167 * Added new function into lib/silcclient/client.[ch]:
7168 silc_client_start_key_exchange to start key exchange after
7169 connection has been established to server. The code internally
7170 now uses this funtion but its main purpose was to provide it
7171 for applications that perform their own connecting. After
7172 application has created a connection it merely calls this
7173 function to start the key exchange between client and server.
7174 The library takes care of everything else after that.
7176 Updated also lib/silcclient/README to explain the usage of
7179 * Do not send to application information that connection has
7180 been established. Application gets notified it by connect
7183 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Applied cras's patch to add silc_schedule_one function. The
7186 function runs scheduler once and returns.
7188 * Fixed the scheduler after cras messed it up. The timeout
7189 handling works now as it's supposed to work.
7191 * Added into lib/silccore/ silcnotify.h to include notify
7192 message types support. Changed silc_server_send_notify*
7193 functions, in server.[ch], to support those new notify types.
7194 Added the support for the notify types into client library,
7195 as well. Added new notify client operation into ops.h in
7198 * Changed silc_server_packet_send_to_channel to send normal
7199 packets instead of just channel message packets. The function
7200 is now used to send the notify packets to channels. It is not
7201 used to send channel message packets anymore, as server never
7204 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7205 va_arg()s as it seems to require it nowadays. I guess, if SILC
7206 is compiled with older va_arg() the new code should work anyway.
7208 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Splitted core library. Core library (lib/silccore) includes
7211 now only SILC protocol specific core (and common) components.
7212 Created new utility library (lib/silcutil) that includes more
7213 generic purpose stuff. The stuff for util library was taken
7214 from the old core library. This was minor and easy split.
7216 * Created SILC Client Library (lib/silcclient) that includes
7217 implementation of the SILC client without user interface. This
7218 was major move from silc/ directory. The code has been changed
7219 so that it is transparent towards the user interface. The
7220 silc/ directory includes now the same user interface as before
7221 and it uses the new client library. Read lib/silcclient/README.
7222 Basicly, the client library performs everything else related
7223 to SILC except user interface handling. Also, configuration
7224 files are considered to be part of user interface and library
7225 does not handle them.
7227 This change also changed a lot of structures, function naming etc.
7228 Most important change was that SilcClientWindow object was
7229 renamed to SilcClientConnection in the client library. Created
7230 also new file lib/silcclient/ops.h. Also added new files
7231 silc/local_command.[ch] and silc/client_ops.[ch].
7233 All these changes were made to make it easier for user interface
7234 designers to create what ever user interface for the SILC client
7237 It is also expected that the server will be moved to lib
7238 directory as well and SILC Server Library will be created;
7239 sometimes in the future.
7241 * Removed Local commands from lib/silccore/silccommand.h as
7242 they are application specific and new client library does not
7243 handle any of those anymore.
7245 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7246 old client implementation in silc/.
7248 * Added support for callback functions in SILC_LOG_* macros.
7249 Application can now set its own callbacks that will be called
7250 instead of using the default functions that will always print
7251 the debug messages to stderr (or stdout). Also, debugging can
7252 now be disabled by setting silc_debug to FALSE and re-enabled by
7253 setting it to TRUE. Note, that logging will still work even
7254 if debugging is disabled.
7256 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7257 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7258 silc_log_reset_debug_callbacks.
7260 * To enable debugging in silc client one must give now -d
7261 option on command line.
7263 * Changed silc_schedule_init to automatically allocate task queues
7264 if they are not allocated before calling it.
7266 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added GMP 3.1 into math library.
7270 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7273 a channel in SILC network. The packet is used by servers and
7274 routers to notify other routers that user has left a channel.
7275 This little feature was missing until now. Added the feature
7276 to protocol specification as well.
7278 Added functions: silc_server_send_remove_channel_user and
7279 silc_server_remove_channel_user into server.[ch].
7281 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7282 lib/silccore/silcpacket.h. However, they are not implemented
7285 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7287 * Fixed joining to a channel and sending channel messages
7288 between server and router. The channel message sending should
7289 now work inside a cell.
7291 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Fixed the private message sending between server and router.
7294 The private message sending should now work inside a cell.
7296 * Added silc_server_replace_id into server.[ch] to replace
7297 existing ID in the SILC network.
7299 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7300 and silc_idlist_replace_server_id into idlist.[ch] in server.
7302 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * Fixed the server to server connections. Server can again now
7305 connect to router. Router to router connections probably does
7308 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Added dynamic protocol registering support. Now protocols can
7311 registered and unregistered on the fly. Patch by cras.
7313 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7315 * Added lib/contrib directory to hold routines that some platforms
7316 don't have but are needed by SILC.
7318 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7319 into lin/contrib to provide getopt() and getopt_long() for
7320 those who don't have it.
7322 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Added AWAY command to client. When away message is set and
7325 client receives a private message packet the client automatically
7326 replies to the sender with the away message.
7328 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7329 bug seemed to be the cause of recent problems when compiling
7332 * Added version detection support to SKE protocol specification
7333 and added the new changes to the SKE implementation as well.
7334 There were other minor changes in the SKE protocol as well.
7336 Many changes in lib/silcske/silcske.[ch] and in
7337 lib/silcske/payload.[ch].
7339 * Added ^U functionality, clear input line. Patch from cras.
7341 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Mainly small bugfixes on core library. Fixed some debugging
7344 logging and buffer overflow in silclog.c.
7346 * Updated config.sub and config.guess on the distribution tree.
7348 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Added command lagging support in server. Client may execute
7351 commands now only once in two seconds.
7353 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7355 * Optimized packet reception. MAC computation and checking is now
7356 also more optimized. A lot previously duplicated code is now
7357 used as generic by both client and server.
7359 * Fixed key pair generation in clientutil.c
7361 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7363 * Added into lib/silccore/silcbufutil.[ch] new function;
7364 silc_buffer_realloc.
7366 * Moved generic packet sending/encryption functions to
7367 lib/silccore/silcpacket.[ch] from client and server. Some
7368 rewriting of the functions.
7370 * Moved all generic packet reception/decryption functions to
7371 lib/silccore/silcpacket.[ch] from client and server. The
7372 packet processing is now much cleaner in both client and server.
7373 These were major changes in both client and server.
7375 * Created many common functions in server to do packet sending.
7376 Previously code were duplicated a lot, this has been removed
7379 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7381 * Rewrote major parts of the ID cache system. Don't know
7382 whether it is better now or not but at least the API is more
7385 * Major rewrite on ID cache stuff on client because of the ID
7386 cache API changes. Added idlist.c to client.
7388 * Also major rewrite on ID cache stuff on server as well.
7389 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7390 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7391 in hand, instead they are all put into the ID cache system now.
7392 All server_idlist_* routines uses ID cache now instead of
7393 traversing its own lists (those lists does not exist anymore).
7394 SilcIDList though still exists. Also, SilcXXXEntry's are
7397 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Finally made the SKE implementation compliant to the protocol
7400 specification. All mp integers are now binary encoded as
7401 opposed being HEX encoded.
7403 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7406 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7407 functions: silc_[encode/decode]_pem. Also added function
7408 silc_encode_pem_file to PEM encode with newlines ('\n') for
7411 * SILC public keys are now encoded either PEM or binary. Same
7412 option is for private keys as well. By default private keys
7413 are binary encoded and public keys PEM encoded. Silly HEX
7414 encoding were removed.
7416 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7417 function to create fingerprints.
7419 * Fixed a bug in SHA1; does not change the original data anymore.
7421 * Partly implemented INFO command on client and server side.
7422 Fixed CLEAR command. Changes to SERVER command; show current
7423 server(s) when giving command without arguments. Added
7424 VERSION command to client.
7426 * Added check to server that unregistered connections cannot
7427 execute commands (unless it is specificly allowed).
7429 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Fixed screen refresh.
7433 * Fixed channel joining bug from client. On some circumstances
7434 client tried to join to a channel it had already joined.
7436 * Added public key verification process into client's protocol.c.
7437 The client now verifies the public key from user and saves
7438 it into ~./silc/serverkeys/ directory.
7440 Added into: clientutil.[ch]: silc_client_verify_server_key.
7442 * Changed SKE protocol's silc_ske_initiator_finish function
7443 to accept callback function that verifies the received public
7444 key. Removed old silc_ske_verify_public_key function.
7446 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7449 silc_pkcs_private_key[_data]_set.
7451 * Made the password and public authentication more cleaner in
7452 server's protocol.c.
7454 * Removed historic and obsolete protocol `channel_auth' from
7455 both client and server.
7457 * Removed wrong way of sending command status messages from
7458 server to client in server's command.c. The old way violated
7459 protocol specification.
7461 Changes to silccore/silccommand.[ch]: removed
7462 silc_command_encode_status_payload -> not needed anymore,
7463 changed silc_command_encode_payload_va to accept extra
7464 argument on variable argument list. The argument type must
7465 now be provided to the function. Also, added new function:
7466 silc_command_encode_reply_payload_va which is same as
7467 normal command_encode_payload_va except command status type
7468 is provided as extra argument.
7470 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Added ~./silc directory handling. The directory includes the
7473 public and private keys for the client.
7475 Added silc_client_check_silc_dir, silc_client_create_identifier
7476 and silc_client_load_keys.
7478 * Implemented SILC protocol compliant public key. Added public
7479 and private key saving to and loading from files.
7481 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7482 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7483 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7484 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7485 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7487 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7488 silc_pkcs_load_[public/private]_key.
7490 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Added silc_server_get_route (route.[ch]) to get connection
7493 data for the fastest route for given ID.
7495 * Implemented INVITE command on client and server. The command
7496 were re-defined in the SILC Protocol Specification and the
7497 implementation now complies with the specification.
7499 * Implemented PING command on client and server.
7501 * Implemented NAMES command on client and server. The server side
7502 supports currently only normal server not router server yet.
7503 Some changes to NAMES definition in SILC protocol specification.
7505 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7507 * Implemented LEAVE command on client and server.
7509 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7510 again. This change was made to the protocol as well. Server
7511 should not violate the protocol specification anymore.
7513 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7516 was tested. SOCKS4 was not but should work anyway.
