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

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

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

360 * ROBOdoc documented lib/silcutil/silcmemory.h.
361 Added also new function silc_memdup.
363 * Removed lib/silcutil/silcbufutil.h and moved those routines
364 to the lib/silcutil/silcbuffer.h.
366 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
368 * Added `user_count' to the SilcChannelEntry which now tells the
369 number of users on the channel. The user count is now saved
370 in normal server of global channels as well. Affected files
371 silcd/server.c, idlist.h, packet_receive.c and command.c.
373 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
374 include file utility functions.
376 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
377 instead of calling directly OS routines.
379 * Fixed NICK change printing in Irssi SILC Client. Fixed
380 KICKED notify printing in Irssi SILC Client. Affected file
381 irssi/src/silc/core/client_ops.c.
383 * Fixed a NICK change bug in client library, to not recreate the
384 client_entry->channels hash table everytime nick is changed.
385 Affected file lib/silcclient/client.c.
387 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
389 * ROBOdoc documented the lib/silcske/silcske.h, and improved
390 the SKE interface a bit.
392 * Fixed padding problem in PKCS#1. The padding was not actually
393 random since the random number generator was used incorrectly.
394 This security bug affects only when encrypting with PKCS#1, and
395 it is not currently used at all in SILC. SILC only use signing
396 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
398 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
400 * Rewrote the notify handling in Irssi SILC client to not call

408 * Added following new config file settings:
409 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
410 key_exchange_timeout, conn_auth_timeout, connections_max,
413 Implemented all the new config settings handling in the server.
415 Optimized the use of SKE Mutual flag usage. Use it only
416 if connection authentication protocol is not based in public
419 Renamed all SilcServerConfigSection* to SilcServerConfig*
420 to have a bit shorter names.
422 Affected files silcd/serverconfig.[ch], server.[ch], and
425 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
427 * Cleaned up the listening sockets code, preparing for the rehash
428 support. Affected file is silcd/server.c.
430 * Fixed some output messages. Affected files are silcd/silcd.c,
433 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
435 * Create lib/doc/silcrng_intro.html document as introduction
436 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.

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

532 * Fixed some silclog documentation. Affected file is
533 lib/silcutil/silclog.h.
535 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * The silc_cipher_register, silc_hash_register and
538 silc_hmac_register now checks if the object to be registered
539 is registered already. Affected files are
540 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
542 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

589 is changed and +k mode is set in the channel. Affected file
590 irssi/src/silc/core/silc-channels.c.
592 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
593 SILC_LOG_WARNING to give out Warning and not Error. Affected
594 file lib/silcutil/silclog.c.
596 * Fixed the channel message payload decryption in the function
597 silc_channel_message_payload_decrypt to not modify the original
598 buffer before it is verified that the message decrypted
599 correctly. Otherwise, next time it is called with correct
600 channel key it won't encrypt since the payload is corrupted.
601 Affected file lib/silccore/silcchannel.c.
603 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
605 * Do not constantly resize the window. A fix patch by cras.
606 Affected file irssi/src/fe-text/screen.c.
608 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
611 Affected file lib/silcutil/silcnet.c.
613 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Fixed a bug in hash table internal routine for traversing
616 the table with foreach callback. The current entry may
617 become invalid in the callback but it was referenced after
618 the callback returned.
620 Do not allow auto rehashing of hash table during the
621 silc_hash_table_foreach operation, for same reasons as it is
622 not allowed for SilcHashTableList. Affected files are
623 lib/silcutil/silchashtable.[ch].
625 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Defined DLLAPI into silcincludes.h and silcwin32.h for
628 Win32 DLL. extern's in header files are now declared with
631 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed private message handling. It used some old code that
634 caused the client to crash. Affecte file is
635 lib/silcclient/client_prvmsg.c.
637 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Added function silc_client_add_channel,
640 silc_client_replace_channel_id, and removed functions
641 silc_client_new_channel_id and silc_idlist_get_channel_by_id
644 * Added cross reference of the joined channels to the
645 SilcClientEntry, and changed the SilcChannelEntry's
646 users list to SilcHashTable. The affected files are
647 lib/silcclient/idlist.[ch].
649 * Fixed a bug in hash table tarversing. While the hash table
650 is traversed with SilcHashTableList the table must not be
651 rehashed. It is now guaranteed that auto rehashable tables
652 are not rehashed while tarversing the list. Also defined that
653 silc_hash_table_rehash must not be called while tarversing
654 the table. Added function silc_hash_table_list_reset that must
655 be called after the tarversing is over. The affected files are
656 lib/silcutil/silchashtable.[ch].
658 * Changed all hash table traversing to call the new
659 silc_hash_table_list_reset in server and in client library.
661 * Added function silc_client_on_channel to return the
662 SilcChannelUser entry if the specified client entry is joined
663 on the specified channel. This is exported to application as
664 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
666 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * Fixed founder regaining problem with JOIN command on normal
669 server. The notify for mode change must be sent always and
670 not only if !cmd->pending. Affected file silcd/command.c.
672 * Fixed the WHOWAS command's reply sending to support the
673 lists correctly. Affected file silcd/command.c.
675 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
677 * When sending JOIN command to router for processing the
678 sender's old command identifier was not saved back to the
679 sender's command context, fixed now. The affected file is
682 * Create the key in JOIN command of the router did not return
683 the channel key, added check for this. Affected file is
686 * Fixed a channel ID update bug in JOIN command reply. Do
687 not directly upgrade the ID but call the function
688 silc_idlist_replace_channel_id if the ID was changed.
689 Affected file silcd/command_reply.c.
691 * Fixed memory leaks from command calling if it would fail.
692 Affected file silcd/command.c.
694 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
696 * Applied patches from cras:
698 Memory leak fixes around libaries, irssi window resize fix,
699 new silclist.h and silcdlist.h, all extern inline changed to
702 * Removed dotconf from lib/dotconf, not needed anymore.
704 * Removed TRQ from lib/trq, not needed anymore.
706 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
707 with server connections. Later this will be configurable
708 in config file after new config file is done. Affected file
711 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Fixed a crash in server related to channel announcements.
714 Affected file silcd/server.c.
716 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Fixed memory leaks in silc_server_create_new_channel*
719 functions. Affected file silcd/server.c.
721 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
722 which ID was changed. This way the router will send the
723 user list for the channel again, and server won't be in
724 desync in some rare circumstances. Affected file is
725 silcd/packet_receive.c.
727 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Check for NULL socket pointer in the function
730 silc_server_packet_send_to_channel_real. Affected file
733 * Fixed the BAN notify handling to correctly remove ban
734 list. Affected file silcd/packet_receive.c.
736 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
738 * Fixed some header addition to Toolkit distribution in
739 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
741 * Added lib/silcclient/client_ops_example.h as an template
742 file for application programmers to quickly start using
743 the SilcClientOperation functions in their application.
744 Updated the lib/silcclient/README as well to tell about this
745 nice file made available.
747 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Call silc_server_remove_from_channels when removing client
750 entry when NO_SUCH_CLIENT_ID was received. Affected file
751 is silcd/command_reply.c.
753 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
755 * Added server & router operator statistics updating. Affected
756 file silcd/packet_receive.c and silcd/command.c.
758 * Fixed the SERVER_SIGNOFF notify handling on normal server
759 not to save the history information for clients. Same was
760 fixed earlier in remove_clients_by_server function, but not
761 here. Affected file silcd/packet_receive.c.
763 * Raised the default connection-retry count from 4 to 7 in
764 server. Affected file silcd/server.h.
766 * Cancel any possible reconnect timeouts when we start the
767 key exchange. Affected file silcd/server.c.
769 * Do not reconnect on connection failure when SCONNECT was
770 given. Affected files silcd/server.[ch].
772 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
776 * Fixed the NICK command to always give the unformatted
777 nickname to the one giving the NICK command. If unformatted
778 nickname is cached already it will be formatted and the
779 local entry will always get the unformatted nickname.
780 Affected file lib/silcclient/idlist.c.
782 * Fixed some double frees from client library commands.
783 Affected file is lib/silcclient/command.c.
785 * Fixed CUMODE command in server to assure that no one can
786 change founder's mode than the founder itself, there was a
787 little bug. Affected file silcd/command.c.
789 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
791 * Removed the SilcClientCommandDestructor from the client
792 libary, it is not needed anymore. Affected files are
793 lib/silcclient/silcapi.h, command[_reply].[ch],
794 client_notify, idlist.c.
796 * Fixed GETKEY command to first resolve client, and then
797 resolve the server only if the client was not found, instead
798 of resolving both at the same time. Affected file is
799 lib/silcclient/command.c.
801 * Added silc_client_start_key_exchange_cb and lookup the
802 remote hostname and IP address before starting the key
803 exchange with server. The affected file is
804 lib/silcclient/client.c.
806 * The server's public key is now saved using the IP address
807 of the server and not the servername for the filename.
808 The hostname public key filename is checked as an fall back
809 method if the IP address based filename is not found.
811 Fixed the GETKEY command to save the fetched server key
814 Print the remote server's hostname now when new key is
815 received during connection process. Affected file is
816 irssi/src/silc/core/client_ops.c.
818 * Return always our own public key to the client if it asks
819 for it with GETKEY command. Affected file silcd/command.c.
821 * Removed the use_auto_addr variable from default config
822 file since it was in wrong section. Affected file is
825 * Fixed TOPIC_CHANGE notification to not route it when it
826 was sent using silc_server_send_notify_to_channel function.
827 Affected file silcd/command.c.
829 * Fixed silc_server_send_notify_kicked to send the kicker's
830 Client ID also, it was missing. Affected files are
831 silcd/command.c, silcd/packet_send.[ch].
833 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Do not save client history information in SERVER_SIGNOFF.
836 Fixes the bug in normal server that it does not detect
837 the client becoming valid after the server becomes back
838 online. Affected file silcd/server_util.c.
840 * Added `sock_error' field into the SilcSocketConnection
841 context. When error occurs during socket operation (read
842 or write) the error is saved. Added also new function
843 silc_socket_get_error to return human readable socket error
844 message. Affected files are lib/silcutil/silcsockconn.[ch],
845 lib/silcutil/unix/silcunixsockconn.c, and
846 lib/silcutil/win32/silcwin32sockconn.c.
848 * The server now prints the socket error message in the
849 signoff for client. Affected file silcd/server.c.
851 * Fixed the `created' channel information sending from router
852 to server in JOIN command. Checks now whether the channel
853 really was created or not and set it according that.
855 Fixed the JOIN command to use the client entry's current
856 ID during the joining procedure instead of the one it sent
857 in the command (it is checked though), since it can change
858 between the packet processing and command processing, and
859 would just case unnecessary pain in the client end. Affected
860 file silcd/command.c.
862 * Fixed a channel key payload sending to use correct channel
863 ID when the server was forced to change the channel's ID by
864 router. Router sent the key payload with the old Channel ID.
865 Affected file silcd/packet_receive.c.
867 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
869 * Call silc_server_save_channel_key only if the key payload
870 was provided in the JOIN command's command reply. Affected
871 file silcd/command_reply.c.
873 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
875 * Fixed silc_mp_sizeinbase to return the value correctly with
876 MPI. Affected file lib/silcmath/mp_mpi.c.
878 * Fixed the stop_server signal to correctly stop the scheduler
879 and gracefully stop the server when SIGTERM or SIGINT signals
880 are received. Affected file silcd/silcd.c.
882 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
884 * Simple handling of TERM and HUP signals. Also added some log
885 flushing call around. Affected file is
888 * Fixed small bugs in silclog.c. Now buffering output will take
889 effect after 10 seconds since startup: This will ensure that
890 no important startup messages are lost. Also output redirection
891 will preserve original format ([Date] [Type] message).
892 Affected file is lib/silcutil/silclog.c.
894 * Added two options to the config file, in the logging section:
895 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
896 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
898 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
900 * Do not print the warning about log files not being initialized
901 more than once to avoid excess logging. Affected file is
902 lib/silcutil/silclog.c.
904 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
905 the SIM copying in make install in Makefile.am.pre.
907 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
909 * Rewritten silclog APIs. Globally interesting changes follows:
910 silc_log_set_files() changed to silc_log_set_file().
911 silc_log_set_callbacks() changed to silc_log_set_callback().
912 ROBOdoc documented silclog header file.
913 SilcLogCb now returns bool to wether inihibit the default
914 handler or not (to keep the old behaviour return always TRUE).
915 The new APIs should also fix the problem of the
916 silcd_error.log file that was written in the current directory.
919 Log files streams will remain opened after silc_log_set_file()
920 call, means less CPU usage notably on high traffic servers.
921 File streams are now full buffered, and flushed to the disk
922 every 5 minutes, lesses HD activity and CPU usage.
923 Messages can be redirected, allowing admins to configure
924 one single logfile for all server messages.
925 the silc_log_quick global variable to activate fast-logging.
926 Affected files lib/silcutil/silclog.[ch]
928 * Changed some code to conform new silclog APIs. Affected
929 files are doc/example_silcd.conf.in, silcd/server.c
930 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
933 * Fixed a memory leak that could occur in some situations.
934 Affected file silcd/serverconfig.c.
936 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
938 * Added the silc_client_del_client to remove the client from
939 all channels as well. Affected file lib/silcclient/idlist.c.
941 * Fixed the client library to correctly remove the client
942 from all channels when the client entry is being destroyed.
943 Affected file lib/silcclient/client_notify.c, command.c.
945 * Added auto-nicking support to the client library. If the
946 applicatio now sets client->nickname it will be sent to the
947 server after connecting by the library. This way for example
948 SILCNICK (or IRCNICK) environment variables will have effect
949 and always change the nickname automatically to whatever
950 it is wanted. Affected file lib/silcclient/client.[ch].
952 * Renamed silc_server_command_bad_chars to the
953 silc_server_name_bad_chars and moved it to the
954 silcd/server_util.[ch]. Added also new function
955 silc_server_name_modify_bad to return nickname that
956 includes bad characters as new nickname without those
957 bad characters. This check and modify is now used in
958 silc_server_new_client when the username is initially set
959 as nickname, so it must be checked to be valid nickname.
960 Affected file silcd/packet_receive.c.
962 * The nickname length is now taken from the packet for real
963 and not trusted to strlen() since it clearly can return
964 wrong length for nickname including bad characters. This
965 also applies to channel names. Affected file silcd/command.c.
967 * Removed the lib/silcsilm/modules directory. Modules are now
968 compiled into the lib/silcsim. Fixed the copying of the
969 modules to follow symbolic links in Makefile.am.pre.
971 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
973 * Fixed silc_string_regexify list creation. Fixes bugs with
974 BAN and INVITE commands in server. The affected file is
975 lib/silcutil/unix/silcunixutil.c.
977 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
979 * Removed the command destructor entirely from the server's
980 command and command reply routines. It is not needed, and
981 its usage was buggy and caused crashes. Affected files are
982 silcd/command[_reply].[ch].
984 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
986 * Cancel protocol and NULL sock->protocol if timeout
987 occurred during protocol. Affected file silcd/server.c.
989 * Cancel protocol timeouts always before calling the final
990 callback, to assure that after final callback is called
991 no other state will be called for the protocol anymore.
992 Affected file silcd/protocol.c.
994 * Print error log if incoming connection configuration could
995 not be found. Affected file silcd/server.c.
997 * Fixed JOIN command to correctly save the founder mode
998 to the client on normal SILC server, when the channel
999 was created by the router. Affected file silcd/command.c.
1001 * Fixed LIST command (hopefully) to send correct reply
1002 packets. Affected file silcd/command.c.
1004 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * The silc_packet_receive_process now returns FALSE if the
1007 read data was invalid packet, and TRUE if it was ok.
1009 The server now checks that if unauthenticated connection
1010 sends data and its processing fails the server will close
1011 the connection since it could be a malicious flooder.
1013 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1015 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Make sure the warning about error opening a log file is
1018 printed only once and not everytime it fails (produces
1019 too much useless log). Affected file lib/silcutil/silclog.c.
1021 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1023 * Made the silc_server_daemonise() function more readable.
1024 Affected file silcd/server.c.
1026 * Pid file is now optional, the user may comment it out from
1027 the config file. Removed define SILC_SERVER_PID_FILE, we
1028 don't need a default any longer. Affected file
1029 configure.in.pre, lib/Makefile.am.pre.
1031 * Make some use of the pid file. The server now dies at startup
1032 if it detects a valid pid file on his path. The server would
1033 die anyway in this circumstance, because of the bind() failure.
1034 Affected file silcd/silcd.c.
1036 * No longer compiling lib/dotconf.
1038 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1040 * Fixed JOIN command parsing not to crash. Affected file
1041 lib/silcclient/command.c.
1043 * Fied the NICK_CHANGE notify to add the new client entry
1044 even it is resolved. This removes an <[unknown]> nick
1045 thingy bug in the client. Affected file is
1046 lib/silcclient/client_notify.c.
1048 * Do not try to allocate 0 bytes (efence does not like it)
1049 in lib/silccore/silccomand.c when encoding payload.
1051 * Do not take IRCNICK as nickname in Irssi SILC client since
1052 it is not possible to set nickname before hand connecting
1053 the server (TODO has an entry about adding auto-nicking
1056 * Changed the silc_server_command_pending to check whether
1057 there already exists an pending entry with the specified
1058 command, command identifier and pending callback. This is
1059 to fix IDENTIFY and WHOIS related crashes that may register
1060 multiple pending commands with same identifier. Affected
1061 file silcd/command.c.
1063 * Fixed the server to reconnect to the router even if it
1064 was already reconnecting and EOF was received. This to
1065 fix a possibility that the server wouldn't ever try to
1066 auto-reconnect to the router. Affected file silcd/server.c.
1068 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Fixed the server's password authentication to use the
1071 length of the locally saved password, and not the one
1072 sent in the packet. Affected file silcd/protocol.c.
1074 * Fixed same password authentication problem in the
1075 Authentication Payload handling routines in
1076 lib/silccore/silcauth.c.
1078 * Yet another password authentication problem fixed with
1079 channel password handling in silcd/command.c.
1081 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * If first character of string in silc_parse_userfqdn is '@'
1084 then do not parse it. Affected file is
1085 lib/silcutil/silcutil.c.
1087 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Fixed minor bug in IDENTIFY command reply sending, which
1090 caused various weird problems during JOIN when it was
1091 resolving names for users. Affected file silcd/command.c.
1093 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1095 * Fixed the IDENTIFY command reply sending to chech better valid
1096 clients. It was possible to send incomplete list of replies.
1097 Affected file silcd/command.c.
1099 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Added silc_client_command[s]_[un]register functions now to
1102 dynamically register the commands in client library. Removed
1103 the static table of commands. This allows the client library
1104 to call commands without causing the application to know about
1105 what commands library has called.
1107 Removed the INFO command reply kludge to detect when the command
1108 was called by library. Now library use its own command reply
1109 function for INFO command.
1111 Added function silc_client_command_call to call a command.
1112 Application can use it to call command, not access the structure
1115 Now all commands that are sent by the client library (not
1116 explicitly sent by application) use own command reply functions.
1118 Affected files around lib/silcclient/ and in
1119 irssi/src/silc/core/.
1121 * Fixed the WHOIS command reply sending to chech better valid
1122 clients. It was possible to send incomplete list of replies.
1124 Fixed the WHOIS and IDENTIFY to send the request to router
1125 if normal server did not do it and did not find any results.
1127 Affected file silcd/command.c.
1129 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Moved the internal data from SilcClient context into its
1132 own file, not accesible to application. Affected files
1133 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1134 and other files in client library.
1136 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Added doc/examples installation target in Makefile.am.pre.
1141 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1143 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1144 commands the found client entry will be removed from the
1145 cache, after notifying application about the error. Affected
1146 file lib/silcclient/command_reply.c.
1148 * Changed the /MSG to check for exact nickname user gave, and
1149 not let `nick' match `nick@host' if it is only one found. Now,
1150 user must type the exact nickname (like nick@host2) even if
1151 there are no more than one same nicks found. This is to avoid
1152 a possibility of sending nickname to wrong nickname since
1153 `nick' could match `nick@host'. Affected file is
1154 irssi/src/core/silc-servers.c.
1156 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1158 * Do not print "you are now server operator" or similar when
1159 giving /away command. Affected files are
1160 irssi/src/silc/core/client_ops.c, silc-servers.h.
1162 * Made the silc_server_command_pending_error_check to send
1163 the same command reply payload it received back to the
1164 original sender of the command. This way all arguments
1165 that was received by the server will be received by the
1166 client too. Affected file silcd/command.c.
1168 * Added the silc_idcache_add to return the created cache entry
1169 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1171 * Add global clients to expire if they are not on any channel.
1172 This is because normal server will never know if they signoff
1173 if they are not on any channel. The cache expiry will take
1174 case of these entries. This is done by normal servers only.
1175 The affected files are silcd/command_reply.c,
1176 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1178 * If server receives invalid ID notification for WHOIS or
1179 IDENTIFY and the ID exists in the lists, it is removed.
1180 Affected file silcd/command_reply.c.
1182 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1183 in client then client entry that it matches is searched and
1184 the nickname is printed on the screen for user. Affected
1185 file irssi/src/silc/core/client_ops.c.
1187 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * Use cache entry expire time in the LIST command reply to
1190 purge old entries from the cache after the LIST command
1191 reply has been received. This way we don't have non-existent
1192 entries in the cache for too long. Affected file is
1193 silcd/command_reply.c.
1195 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * If we are normal server, and we've not resolved client info
1198 in WHOIS or IDENTIFY from router, and it is global client,
1199 we'll check whether it is on some channel. If it is not
1200 then we cannot be sure about its validity and will resolve it
1201 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1202 file silcd/command.c.
1204 * Search channel by name (if possible) rather than by ID
1205 in IDENTIFY command's command reply. Affected file is
1206 silcd/command_reply.c.
1208 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1211 Updated specs and implemented it. Affected file silcd/command.c,
1212 silcd/packet_send.c and silcd/packet_receive.c.
1214 * Implemented the <founder auth> payload handling in the JOIN
1215 command. If provided all conditions for channel joining
1216 except requirement to provide correct passphrase can be
1217 overrided by the channel founder. Updated the protocol specs.
1218 Affected file silcd/command.c.
1220 Added support for founder auth in JOIN command in client
1221 library. Fixed the parsing of the JOIN command now to support
1222 all options as they should be. The affected file is
1223 lib/silcclient/command.c.
1225 * Optimized the WHOIS and IDENTIFY commands to send the request
1226 to router only if it includes nicknames or other names. If
1227 they include only IDs then check the local cache first before
1228 routing. Affected file is silcd/command.c.
1230 * Added channels topic announcements. Affected file is
1231 silcd/packet_receive.c and silcd/server.c.
1233 * Fixed the silc_server_send_notify_topic_set to really destine
1234 the packet to channel. Affected file silcd/packet_send.c.
1236 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1237 library. Affected file lib/silcclient/client_notify.c.
1239 * Added UMODE announcements. Affected file silcd/server.c.
1241 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1243 * Memory leak fixes in:
1245 lib/silcutil/silcsockconn.c
1246 lib/silcske/silcske.c
1247 lib/silcske/groups.c
1249 lib/silccrypt/silcpkcs.c
1250 lib/silccore/silccommand.c
1251 lib/silccore/silcidcache.c
1256 * ROBOdoc documented the lib/silcske/groups.h file and a
1257 bit changed the interface for better.
1259 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1261 * Update the client entry context in the ID cache after
1262 nick change. Affected file lib/silcclient/command.c.
1263 Fixes the CUMODE command when regaining founder privileges,
1264 and a little WHOIS problem.
1266 * Fixed silc_net_gethostbyname to correctly call the
1267 inet_ntop. Affected file lib/silcutil/silcnet.c.
1269 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1271 * Added IPv6 support checking to the configure.in.pre, added
1272 also --enable-ipv6 option to override the check. Affected
1273 file configure.in.pre.
1275 * The silc_thread_create now calls the start function
1276 directly if threads support is not compiled in. Removes
1277 ugly #ifdef's from generic code. Affected files are
1278 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1280 * Added silc_net_gethostby[name/addr]_async to asynchronously
1281 resolve. Affected files are lib/silcutil/silcnet.[ch].
1283 * Added support for rendering IPv6 based server, client and
1284 channel IDs. Affected file lib/silcutil/silcutil.c.
1286 * Added support for creating IPv6 based server IDs. Affected
1287 file is silcd/serverid.c.
1289 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1291 * Added silc_net_gethostby[addr/name] into the
1292 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1293 routines. Added silc_net_is_ip[4/6]. Affected file is
1294 lib/silcutil/unix/silcunixnet.c. All routines that take
1295 address as argument now supports both IPv4 and IPv6 addresses.
1297 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1299 * Fixed LIST command reply sending in server. Affected file
1302 * Server now sends the kicker's client ID in the KICK notify
1303 to the kicked client. Affected file silcd/command.c.
1305 * The client library now parses the kickers client ID and
1306 UI displays it. Affected files lib/silcclient/client_notify.c
1307 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1309 * Made all payload parsing function prototypes consistent.
1310 They all take now const unsigned char * and uint32 pair as
1311 the payload data instead of SilcBuffer. Changes all around
1312 the source tree. Other unsigned char* -> const unsigned char*
1313 changes around the tree as well.
1315 * Optimized SFTP client and server packet sending not to
1316 allocate new buffer for each packet but to recycle the
1317 first allocated buffer. Affected files are
1318 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1320 * Optimized the SFTP client to use SilcList instead of
1321 SilcDList for requests, because it is faster. Affected file
1322 is lib/silcsftp/sftp_client.c.
1324 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1325 into lib/silccore/silcid.[ch].
1327 Renamed silcpayload.[ch] into silcargument.[ch].
1329 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1331 * If client entry is deleted with active key agreement
1332 session, abort the session.
1334 The silc_client_abort_key_agreement now calls the completion
1335 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1337 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1340 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Don't use __restrict in older GCC's. Affected file is
1343 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1345 * silc_net_localhost now attempts to reverse lookup the
1346 IP/hostname. Affected file lib/silcutil/silcnet.c.
1348 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1349 command. It can be used to gain founder privileges at
1350 the same time when joining the channel.
1352 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1353 kicker's client ID as well. Updated protocol specs.
1355 Defined that the server must send SILC_COMMAND_IDENTIFY
1356 command reply with error status to client who sent
1357 private message with invalid client ID.
1359 Updated the protocol specification.
1361 * Added silc_server_send_command_reply to send any
1362 command reply. Affected file silcd/packet_send.[ch].
1364 * Added silc_id_payload_encode_data to encode ID payload
1365 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1367 * The server now send IDENTIFY command reply with error
1368 status if client ID in private message is invalid. Affected
1369 file silcd/packet_receive.c.
1371 * Save the server key file with server's IP address in
1372 the filename instead of hostname. The affected file is
1373 irssi/src/silc/core/client_ops.c.
1375 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1380 * Added libtool support for compiling shared objects in
1381 lib/silcsim. Affected file configure.in.pre and
1382 lib/silcsim/Makefile.am. Original patch by cras.
1384 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Pid file configuration, and server's config file fixes
1387 patch by toma. Updated CREDITS file.
1389 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Fixed silc_client_channel_message to not try to decrypt
1392 the message twice if it resolved the destination client
1393 information. This could cause of dropping one channel
1394 message. Affected file lib/silcclient/client_channel.c.
1396 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1399 lib/silcclient/client.c. This function is used when the SILC
1400 Client is run under some other scheduler, or event loop or
1401 main loop. On GUI applications, for example this may be
1402 desired to used to run the client under the GUI application's
1403 main loop. Typically the GUI application would register an
1404 idle task that calls this function multiple times in a second
1405 to quickly process the SILC specific data.
1407 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1409 * Fixed silc_server_drop() for dropping the supplementary
1410 groups as well, this could cause a security hole on some
1413 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1418 * Write PID file after dropping privileges. Added -F option
1419 to run server on foreground. A patch by debolaz.
1420 Affected files silcd/server.c, silcd/silcd.c.
1422 * Fixed MOTD to return the MOTD file server name. Affected
1423 file silcd/command.c.
1425 * Added INFO command reply handling to the Irssi SILC Client.
1426 Affected file irssi/src/silc/core/client_ops.c.
1428 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Fixed the silc_idcache_list_* routines to really support
1431 the dynamic list. Fixes a crash. Affected file is
1432 lib/silccore/silcidcache.c.
1434 * Fixed the LIST command reply to really call LIST command's
1435 pending callbacks. Affected file silcd/command_reply.c.
1437 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Update conn->local_entry->nickname after giving NICK
1440 command. Affected file lib/silcclient/command.c.
1442 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1444 * Added the [pid] option to the silcd configuration file
1446 Affected files: serverconfig.[ch] and silcd.c
1448 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Save fingerprint in WHOIS command reply in server.
1451 Affected file silcd/command_reply.c.
1453 * Fixed NICK commands pending callback registration.
1454 Affected file lib/silcclient/command.c.
1456 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Use ++server->cmd_ident when sending commands in server,
1459 instead of random number. Affected file silcd/command.c.
1461 * Fixed GETKEY command reply to call actually GETKEY pending
1462 command callbacks. Affected file silcd/command_reply.c.
1464 * A bit stricter check for nicknames. Check for same nickname
1465 in NICK command also. Affected file silcd/command.c.
1467 * Do not call INFO command everytime client ID changes, only
1468 during first connecting. Affected file lib/silcclient/client.c.
1470 * Set the new nickname only after successful command reply for
1471 NICK command is returned by server. Affected file
1472 lib/silcclient/command.c.
1474 * Remove nicknames from nicklist during server_signoff notify.
1475 Should fix /NAMES bit more. The affected file is
1476 irssi/src/silc/core/silc-channels.c.
1478 * Added `fingerprint' field to the SilcIDListData in the
1479 silcd/idlist.h to hold the fingerprint of the client's
1482 Send the fingerprint of the client's public key in WHOIS
1485 Affected files silcd/command.c, and silcd/idlist.[ch].
1487 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1488 create fingerprint from given data.
1490 * Show the fingerprint of the client's public key in WHOIS.
1491 Affected files irssi/src/module-formats.[ch] and
1492 irssi/src/silc/core/client_ops.c.
1494 * Format the multiple same nicknames also during JOIN and
1495 NICK_CHANGE notifys. Affected file is
1496 lib/silcclient/client_notify.c.
1498 * Do not print error on screen for invalid private message
1499 payload since it can come if someone is sending private
1500 messages with wrong key. Affected file
1501 lib/silccore/silcprivate.c.
1503 * Fixed multiple concurrent /PING crash. Affected file
1504 lib/silcclient/command.c.
1506 * Changed the wrong ID encoding. All IP addresses must be
1507 in MSB first order in encoded format. They were encoded
1508 wrong and was in LSB format. Affected files are
1509 silcd/serverid.c, lib/silcutil/silcutil.c.
1511 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1513 * Call the `connect' client operation through the scheduler
1514 in case of error. Affected file lib/silcclient/client.c.
1516 * Call the `failure' client operation even if the error
1517 occurred locally during a protocol. Affected file is
1518 lib/silcclient/protocol.c.
1520 * Added support of sending LIST command to router from normal
1521 server. This way normal server can get list of all channels
1522 in the network too. Fixed the channel list sending in the
1523 server too. Affected files are silcd/command.c, and
1524 silcd/command_reply.[ch].
1526 * Added silc_server_update_channels_by_server and
1527 silc_server_remove_channels_by_server. They are used during
1528 disconnection of primary router and in backup router protocol.
1529 Affected file silcd/server_util.[ch], silcd/server.c and
1530 silcd/server_backup.c.
1532 * Fixed channel adding to global list in IDENTIFY command
1533 reply in server. Affected file silcd/command_reply.c.
1535 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * If the incoming packet type is REKEY or REKEY_DONE process
1538 that packet always synchronously. Fixes yet another MAC
1539 failed error on slow (dialup) connections. Affected file
1540 lib/silcclient/client.c and silcd/server.c.
1542 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Call check_version SKE callback for initiator too. Affected
1545 file lib/silcske/silcske.c.
1547 * Implemented fix for security hole found in the SKE that was
1548 fixed in the specification few days back; the initiator's
1549 public key is now added to the HASH value computation.
1550 Added backwards support for the old way of doing it too, for
1551 old clients and old servers. Affected file is
1552 lib/silcske/silcske.c.
1554 * Enabled mutual authentication by default in SKE. If initiator
1555 is not providing mutual authentication the responder will
1556 force it. This will provide the proof of posession of the
1557 private key for responder. The affected files are
1558 lib/silcclient/protocol.c and silcd/protocol.c.
1560 * Do not cache anymore the server's public key during SKE.
1561 We do mutual authentication so the proof of posession of
1562 private key is done, and if the server is authenticated in
1563 conn auth protocol with public key we must have the public
1564 key already. Affected file silcd/protocol.c.
1566 * Added new global debug variable: silc_debug_hexdump. If
1567 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1568 file lib/silcutil/silclog.[ch].
1570 * Fixed compilation warning due to char * -> const char *.
1571 Affected files lib/silcutil/silcnet.h, and
1572 lib/silccore/silcauth.[ch].
1574 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * Fixed CMODE command when new channel key was created. If
1577 the creation failed the old key was removed. Next time giving
1578 same command would crash the server since the old key was
1579 freed already. Affected file silcd/command.c.
1581 * Fixed the silc_server_announce_get_channels to not crash
1582 on reconnect. Affected file silcd/server.c.
1584 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Added silc_log_set_debug_string function to set a regex
1587 string to match for debug output. Only the function names,
1588 or filenames matching the given debug string is actually
1589 printed. This way it is possible to filter out those debug
1590 strings that user is not interested in.
1592 Fixed a bug in silc_string_regexify.
1594 Affected files lib/silcutil/silclog.[ch], and
1595 lib/silcutil/unix/silcunixutil.c.
1597 * Changed the -d options in both server and Irssi SILC client
1598 to take the debug string as argument. Affected files
1599 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1601 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Added silc_hash_babbleprint to create a Bubble Babble
1604 Encoded fingerprint. The encoding is developed by Antti
1605 Huima (draft-huima-babble-01.txt), and it creates human
1606 readable strings out of binary data. Affected file
1607 lib/silccrypt/silchash.[ch].
1609 * Print the babble print now in addition of fingerprint as well
1610 in Irssi SILC client. Affected files are
1611 irssi/src/fe-common/silc/module-formats.[ch],
1612 irssi/src/fe-common/silc/core/client_ops.c.
1614 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1616 * Fixed a security problem found in SKE. The initiator's
1617 public key too is now added to the HASH hash value creation
1618 which is signed by the responder to create the SIGN value.
1619 This will prevent anyone in the middle to lie to the responder
1620 about the initiator's public key. If this is done now, the
1621 man in the middle will get caught. Updated the protocol

1660 * Added silc_pkcs_public_key_compare to compare two
1661 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1663 * Check that the client who set the founder mode on the
1664 channel is the same client that is giving the founder
1665 mode to itself. It is done by comparing the saved public
1666 key (it is saved even in the authentication is passphrase).

1675 client library. Affected file lib/silcclient/client.c.
1677 * Fixed the silc_client_packet_parse to not to increase
1678 the packet sequence number if the conn->sock and the
1679 current socket connection is not same. This can happen
1680 for example during key agreement when the conn includes
1681 multiple socket connections (listeners). Affected file
1682 lib/silcclient/client.c.
1684 * The sender of the file transfer request now provides also
1685 the pointer (listener) for the key exchange protocol. If
1686 the listener cannot be created then it sends empty key
1687 agreement and lets the receiver provide the listener.
1689 Added `local_ip' and `local_port' arguments to the
1690 silc_client_file_send. If they are provided they are used,
1691 if not then it will attempt to find local IP address, if
1692 not found or bind fails then the remote client will provide
1695 Affected files are lib/silcclient/client_ftp.c and
1696 lib/silcclient/silcapi.h.

1705 of the client's public key (if the proof of posession of the
1706 corresponding private key is verified by the server).
1707 Updated to the protocol specification.
1709 * Added support of receiving the client's public key's
1710 fingerprint in command reply in client library. Affected
1711 file is lib/silcclient/command_reply.c, and
1712 lib/silcclient/idlist.[ch].

1771 preserve the WHOWAS info for the client. Affected file
1772 silcd/server_util.c.
1774 * Fixed SERVER_SIGNOFF notify handling in the server. The
1775 server is now able to process incoming SERVER_SIGNOFF notify
1776 for a server that it doesn't even know about. It will remove
1777 the clients provided in the notify. Affected file
1778 silcd/packet_receive.c.
1780 * Check for partial packet in data queue after every packet that
1781 was found from the queue. Return and wait for more data if
1782 there is partial data in queue. Affected file is
1783 lib/silccore/silcpacket.c.
1785 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1800 irssi/src/fe-common/silc/module-formats.[ch].
1802 * Wrote a help file for FILE command.
1804 * Added silc_rng_global_get_byte_fast to get not-so-secure
1805 random data as fast as possible. Random data is read from
1806 /dev/urandom if available and from the SILC RNG if not
1807 available. It is used in padding generation. Affected file
1808 lib/silccrypt/silcrng.[ch].
1810 * All packets in client library are now processed synchronously.
1811 Optimized packet processing a lot. Affected file
1812 lib/silcclient/client.c.
1814 * All server connection packets are processing synchronously
1815 now in server, to optimize packet processing. Affected file
1818 * Include files are installed now only in Toolkit distribution
1819 if make install is given. Affected files: all Makefile.am's.
1821 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Assure that silc_client_notify_by_server_resolve does not
1824 resolve the client information multiple times. If it cannot
1825 be found by the first it cannot be found at all. Affected
1826 file lib/silcclient/client_notify.c.
1828 * Fixed WHOWAS command reply calling. Affected file
1829 lib/silcclient/command_reply.c.
1831 * Removed all references to silc_idlist_get_client from the
1832 Irssi SILC client since that call is internal call used by
1833 the library. The Irssi SILC client will use now client
1834 retrieval functions found in silcapi.h.
1836 * Fixed a bug in resolving nickname info before sending
1837 private message. It used freed memory. Affected file
1838 irssi/src/silc/core/silc-servers.c.

1859 * Added silc_net_localip to return local host's IP address.
1860 Affected file lib/silcutil/silcnet.[ch].
1862 * If key exchange or rekey protocol is active for a connection
1863 parse all packets syncronously since there might be packets
1864 in packet queue that we are not able to process without first
1865 processing packets before them. Affected file silcd/server,
1866 lib/silcclient/client.c.
1868 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1869 whether library should continue processing the packet.
1870 Affected file lib/silccore/silcpacket.h.

1920 Make sure also that USERS command reply does not resolve
1921 twice information. Affected file is
1922 lib/silcclient/command_reply.c.
1924 Make sure that silc_client_get_clients_by_list does not
1925 resolve twice same information.
1927 * Check for valid client->id in the silc_server_free_client_data.
1928 Affected file silcd/server.c.
1930 * Fixed /GETKEY nick@server not to crash if the server entry
1931 is not found. Affected file lib/silcclient/command.c.

1943 * Call the silc_server_udpate_servers_by_server in the
1944 primary router that comes back online in the backup resuming
1945 protocol. Otherwise it routes packets wrong. Affected file
1946 silcd/server_util.[ch], silcd/server_backup.c.
1948 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1951 lib/silcutil/silcbuffmt.[ch].
1953 * Redefined the SILC packet header to include the padding
1954 length. Affected file lib/silccore/silcpacket.[ch].
1956 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1957 length for maximum padding up to 128 bytes). Affected
1958 file lib/silccore/silcpacket.h.
1960 * Removed all backwards support for old 0.5.x MAC thingies.
1961 The SILC packet header change makes it impossible to be
1962 backwards compatible.
1964 * Send the ENDING packet with timeout in the backup resuming
1965 protocol. This is to assure that all routers has connected
1966 to the primary router. Affected file silcd/server_backup.c.
1968 * Changed the RNG to take the first IV from random data. It
1969 used to take it from zero actually. Changed the RNG also
1970 to use /dev/urandom during session. /dev/random is used
1971 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1973 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1976 (the packet length) encrypted. Affected files aroung the
1977 code tree, lib/silccore/silcpacket.[ch]. Removed the
1978 SilcPacketCheckDecrypt callback. It is not needed anymore
1979 since the silc_packet_receive_process will determine now
1980 whether the packet is normal or special.
1982 * Implemented the unidirectional MAC keys. Affected files
1983 lib/silcske/silcske.c, silcd/protocol.c and

1991 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Allow backup router to announce servers. All servers
1994 announced by backup router are added to the global list
1995 automatically. Update hte server's socket to our primary
1996 router also when backup router announces a server.
1997 Affected file silcd/packet_receive.c.
1999 * Do not update the client->router in the function
2000 silc_server_udpate_clients_by_server if the client is on
2001 global list. We might fail to find any specific server
2002 for locally connected clients and local cell clients. They
2003 should still use the `from' and not `to' as client->router.
2004 This fixes backup router resuming protocol. Affected file
2005 silcd/server_util.c.
2007 * Decrease channel statistics count only if the channel
2008 deletion worked. Affected files are silcd/server.c and
2009 silcd/server_util.c.
2011 * Added silc_server_update_servers_by_server to update origin
2012 of all server entries. Used during backup router protocol.

2029 to the router it came from. Affected file is
2030 silcd/packet_send.c. Fixed memory leak too.
2032 * Announce informations for incoming router connection, but
2033 only after checking if it is replaced by backup router.
2034 Affected file silcd/packet_receive.c.

2043 silcd/packet_send.c.
2045 * Fixed silc_server_send_notify_dest to set the broadcast
2046 flag. Fixed the silc_server_send_notify_topic to actually
2047 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2048 Affected file silcd/packet_send.c.
2050 * Changed the SFTP Filesystem interface. Changed the
2051 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2052 the filesystem operation function. The SilcSFTPFilesystem
2053 is now a context that is allocated by all filesystem allocation
2054 functions and it already includes the operations structure
2055 and filesystem specific context. It is given as argument
2056 now to the silc_sftp_server_start. This made the interface
2057 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2058 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2060 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Changed the backup router adding and getting interfaces
2063 in the server. The router that will be replaced by the
2064 specified backup router is now sent as argument. Affected

2117 send any data. Affected file lib/silcclient/client.c.
2119 * Implemented the backup router support when the primary router
2120 goes down. The servers and routers can now use the backup
2121 router as new primary router without loosing connectivity.
2123 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2126 in the server to indicate disabled entry. All data read
2127 from the connection will be ignored and no data is sent
2128 for entry that is disabled. Affected files are
2129 silcd/idlist.h, silcd/server.c.
2131 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2145 lib/silcsftp. It includes SFTP client and SFTP server
2148 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Moved lib/silccore/silcprotocol.[ch] to the
2151 lib/silcutil library.
2153 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2154 take variable argument list pointer as argument. Affected
2155 file lib/silcutil/silcbuffmt.[ch].
2157 * Added silc_buffer_set function that is used to set data
2158 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2159 Affected file lib/silcutil/silcbuffer.h.
2161 * Changed various routines in the core library to use the new
2162 silc_buffer_set instead of allocating new buffer only for
2165 * Added 64-bit value formatting and unformatting support to the
2166 silc_buffer_[un]format routines. Affected file is
2167 lib/silcutil/silcbuffmt.[ch].
2169 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2170 to includes/bitmove.h.
2172 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Fixed channel user mode saving in client library. Affected
2175 file lib/silcclient/command[_reply].c.
2177 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Defined the file transfer to the SILC Protocol. Added
2180 new packet type SILC_PACKET_FTP and defined File Transfer
2181 Payload. The mandatory file transfer protocol is SFTP
2182 (SSH File Transfer Protocol). Affected file in addition
2183 of the internet draft is lib/silccore/silcpacket.h.
2185 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2186 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2187 is used as part of backup router protocol when the primary
2188 router of the cell is back online and wishes to resume
2189 the position as primary router.
2191 * Redefined the MAC generation keys in the protocol. The
2192 same key is not used anymore in both direction. Both
2193 direction will now use different keys for sending and
2194 receiving. This fixes a potential security flaw. This
2195 change causes incompatibilities in the protocol.
2197 * Redefined also the MAC computation from the packet.
2198 An packet sequence number is now added to the MAC
2199 computation. This prevents possible replay attacks against
2200 the protocol. This change too causes incompatibilities
2203 Added `sequence' field to the SilcPacketContext to hold
2204 the current sequence number for the packet.
2206 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Added `created' field to the SilcIDListData in the file
2209 silcd/idlist.h to indicate the time when the entry was
2212 * Added `created' field to the SilcChannelEntry too. Affected
2213 file silcd/idlist.h.
2215 * Added `creation_time' aguments to all the announcement functions
2216 in the server. If it is provided then only the entries that
2217 was created after the provided time frame are actually
2218 announced. Affected file silcd/server.[ch].
2220 * The protocol says that the Channel ID's IP address must be
2221 based on the router's IP address. Added check for this in
2222 the silc_server_new_channel when processing incoming New Channel
2223 Payload. Affected file silcd/packet_receive.c.
2225 * Print out the correct version with --version in SILC client.
2226 Affected file irssi/src/silc/core/silc-core.c.
2228 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2230 * Fixed WHOWAS command to check for completnes of the client
2231 entry always, not just when the command is coming from client.
2232 Affected file silcd/command.c.
2234 * Added new function silc_server_packet_queue_purge to purge the
2235 outgoing data queue to the network. After the function returns
2236 it is guaranteed that the outgoing packet queue is empty.
2237 Affected file silcd/packet_send.[ch].
2239 * Purge the outgoing packet queue in the rekey protocol's final
2240 callback to assure that all rekey packets go to the network
2241 before quitting the protocol. Affected file silcd/server.c.
2243 * Added silc_client_packet_queue_parse as similar function as
2244 in server to the client library. The affected file is
2245 lib/silcclient/client.c.
2247 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2249 * Splitted silcd/server.c and created silcd/server_util.[ch]
2250 for utility functions.
2252 * Added new socket flag SILC_SF_DISABLED to indicate that the
2253 connection is open but nothing can be sent to or received from
2254 the connection. Affected file lib/silcutil/silsockconn.[ch].
2255 The checking for disabled socket is checked in the low level
2256 silc_socket_write and silc_socket_read functions.
2258 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Allow only nicknames and channel names that fits into the
2261 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2263 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * When processing JOIN command reply in server check that if
2266 the channel exists in our global list we'll move it the local
2267 list. Affected file silcd/command_reply.c.
2269 * Fixed the check whether client is joined on the channel already
2270 in JOIN command. Affected file lib/silcclient/command.c.
2272 * Fixed the JOIN command reply to check whether the channel
2273 already exists. Affected file lib/silcclient/command_reply.c.
2275 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Added silc_ske_status_string to map the SKE error numbers
2278 to readable strings. The affected files are
2279 lib/silcske/silcske[_status].[ch].
2281 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Do not show the private channels on the WHOIS channel list
2284 as it is not allowed by the protocol. The affected file is
2287 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Assure that the packet length digged from the actual packet
2290 is something sensible in the silc_packet_decrypt_rest_special
2291 in lib/silccrypt/silcpacket.c.
2293 * Free and NULL the allocated pointer in silc_hmac_alloc if
2294 the HMAC allocation fails. The affected file is
2295 lib/silccrypt/silchmac.c.
2297 * Print the selected security properties to the log files in
2298 the server. Affected file silcd/protocol.c.
2300 * Add SKE's reference counter even if calling the completion
2301 callback manually. Otherwise it goes negative, although it
2302 does not cause any problems. The affected file is
2303 lib/silcske/silcske.c.
2305 * Remove the client entry with short timeout after giving the
2306 KILL command. Affected file lib/silcclient/command.c.
2308 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2309 case all found clients are already disconnected (WHOWAS would
2310 found them) in the server. Affected file silcd/command.c.
2312 * Update the last_receive (time of last data received) to be
2313 updated only when received private or channel message so that
2314 the idle time showed in WHOIS makes more sense.
2316 * Added boolean field `valid' in to the SilcClientEntry in the
2317 client library to indicate whether the entry is valid or not.
2318 This fixes the nickname change bug on channel when changing
2319 the nickname to be same than the old (like nick to Nick) the
2320 nickname formatter doesn't set the new nick anymore to Nick@host.
2321 Affected file lib/silcclient/idlist.[ch].
2323 * Now actually fixed the nickname changing on disconnection.
2324 Added new function silc_change_nick to the Irssi SILC Client.
2325 Affected file irssi/src/silc/core/client_ops.c,
2326 irssi/src/silc/core/silc-nicklist.[ch].
2328 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Check that the public key exists in the GETKEY command before
2331 trying to encode it. Affected file silcd/command.c.
2333 * Print some notifications on received public keys with GETKEY
2334 command in the Irssi SILC Client. Affected files are
2335 irssi/src/fe-common/silc/module-formats.[ch],
2336 irssi/src/silc/core/client_ops.c.
2338 * Use IDENTIFY command to resolve the server information in the
2339 GETKEY command instead of INFO command. Affected file
2340 lib/silcclient/command.c.
2342 * All command reply functions in the client library now calls
2343 the pending command reply callbacks even if an error has
2344 occurred. The server has done this a long time and now it was
2345 time to move the client library to this as well. Now all
2346 errors can be delivered back to the pending command reply
2347 callbacks if necessary. Affected files are
2348 lib/silcclient/command[_reply].[ch].
2350 * Change the nickname on disconnection back to the username
2351 because in reconnect the server will enforce it to it anyway.
2352 Affected file irssi/src/silc/core/silc-servers.c.
2354 * Fixed a config file parsing bug in the Irssi SILC client.
2355 Affected file irssi/src/silc/core/clientconfig.c.
2357 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * When printing the channel mode on JOIN, verify that the
2360 channel key and channel's HMAC are valid. Affected file
2361 irssi/src/silc/core/client_ops.c.
2363 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2366 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2367 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2369 * Removed channel key rekey task deleting from the function
2370 silc_server_save_channel_key. Affected file silcd/server.c.
2371 Added explicit timeout task context instead that is used to
2372 delete the task if we are registering a new task before the
2373 new task has elapsed.
2375 * When channel key rekey occurs the client library now saves
2376 the old channel key for a short period of time (10 seconds) and
2377 is able to use it in case some is still sending channel
2378 messages encrypted with the old key after the rekey. Affected
2379 file lib/silcclient/[idlist.h|client_channel.c].
2381 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Added check to the silc_server_new_id_real to not accept
2384 new ID if it is the sender's own ID. Affected file is
2385 silcd/packet_receive.c.
2387 * Assure that we do not announce ourself or the one we've
2388 sending our announcements when we're router and are announcing
2389 servers to our primary router. Affected file silcd/server.c.
2391 * Fixed silc_server_command_identify_check_client to assemble
2392 correct WHOIS packet. It send corrupted WHOIS packet and
2393 caused problem with router to router connections. Affected
2394 file silcd/command.c.
2396 Fixed also silc_server_command_whois_check the same way
2397 as for the IDENTIFY command.
2399 * Added new SilcIDListStatus to the server in the SilcIDListData
2400 structure. The status now includes the current status of
2401 the entry (like registered, resolved etc.). Affected file
2402 silcd/idlist.[ch]. Defined a bunch of different status types
2403 as well. This replaced the old boolean registered field as well.
2405 Added resolve_cmd_ident field to the SilcClientEntry structure
2406 too so that if the entry is for example being resolved so
2407 another command may attach to the same pending command reply
2408 without requiring to resolve the same entry again. This concept
2409 should optimize the WHOIS and the IDENTIFY resolving under
2410 heavy load by taking away unnecessary resolving for entries
2411 that are being resolved already.
2413 Added support for adding multiple pending commands for one
2414 command idenfier. Affected file silcd/command[_reply].[ch].
2416 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2417 before deleting the data. Otherwise the hash table will have
2418 freed data in comparison functions. Affected file is
2419 silcd/command_reply.c.
2421 * Fixed silc_idlist_replace_client_id to add the new entry to
2422 the cache with NULL nickname. Otherwise there will be invalid
2423 memory as the nickname after the nickname is freed. Affected
2424 file silcd/packet_receive.c.
2426 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2427 saved into wrong slots because the previous number of entries
2428 was not taken into account. Affected file silcd/idlist.c.
2429 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2431 * If we are router and we receive JOIN notify to a channel that
2432 does not have any users then notified client is marked as the
2433 channel founder, as it is it. The affected file is
2434 silcd/packet_receive.c
2436 * Added to the extended hash table API's table_del_*ext functions
2437 the destructor as argument too, so that the caller can decide
2438 which destructor to use or whether to use destructor at all.
2439 Affected file lib/silcutil/silchashtable.[ch].
2441 * Fixed ID Cache purging. It actually deleted the entries from
2442 the hash table after the data was freed. The hash table ended
2443 up comparing freed memory. The affected file is
2444 lib/silccore/silcidcache.c.
2446 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Fixed Irssi SILC client's KILL command's HELP syntax.
2450 * The USERS command now resolves the detailed user information
2451 if the userinfo field is missing. Affected file is
2452 lib/silcclient/command_reply.c.
2454 * Do not print error in silc_file_read if the read file does
2455 not exist. Just silently return NULL. Affected file is
2456 lib/silcutil/silcutil.c.
2458 * Fixed the silc_log_output to not wine about NULL filename
2459 and to not create some bogus " " filename. Affected file is
2460 lib/silcutil/silclog.c.
2462 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Fixed various printing bugs on the user interface in the
2465 Irssi SILC Client. Minor changes that were forgotten from
2468 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Fixed the configure.in.pre and the compilation and distribution
2471 environment to support the new autoconf 2.52. That version is
2472 now required to compile the CVS trunk.
2474 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2477 to generally parse user@fqdn format strings. Affected file
2478 lib/silcutil/silcutil.c.
2480 * Added nickname_format and nickname_force_format fields to the
2481 SilcClientParams structure. The first one defines the format
2482 for the nicknames that the library will enforce if the receives
2483 multiple same nicknames. The second one is boolean value and
2484 can be used to force the library to always enforce the format
2485 to the nicknames regardles whether there are multiple nicknames
2486 or not. This configurable formatting was employed to flexibly
2487 support accessing multiple nicknames from the user interface.
2488 The userinterface can now set the nicknames to what ever format
2489 they prefer. Affected file lib/silcclient/silcapi.h.
2491 Added function silc_client_nickname_format to the file
2492 lib/silcclient/idlist.c. It performs the nickname formatting.
2494 Added new field `hostname´ to the SilcClientEntry context.
2495 It holds the hostname of the client. Affected file is
2496 lib/silcclient/idlist.h.
2498 * Irssi SILC Client sets the nicknames in nick@hostn format.
2499 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2500 irssi/src/silc/core/silc-core.c.
2502 The WHOIS printing now also shows both the real nickname and
2503 the formatted nickname so that user knows how to access the
2504 user if there are multiple same nicknames cached. Affected
2505 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2506 printing formatting too to take the hostname now as a separate
2507 argument. The Affected file is
2508 irssi/src/fe-common/silc/modules-formats.[ch].
2510 * Changed the silc_client_get_clients_local to accept the formatted
2511 nickname as argument. It accepts the real nickname too but the
2512 formatted nickname can be used to find the true entry from
2513 multiple entries. Affected file lib/silcclient/silcapi.h and
2514 lib/silcclient/idlist.c.
2516 * Added nickname_format_parse field to the SilcClientParams.
2517 It is a callback function provided by the application to parse
2518 the nickname out of the formatted nickname string. The library
2519 calls it to get the nickname from the formatted string. Since
2520 the application generally knows better the format of the nickname
2521 string it parses it instead of the library, even though library
2522 encodes the formatted string. If the callback function is not
2523 provided then the library will use the string as is. The
2524 affected file is lib/silcclient/silcapi.h.
2526 * All the nickname strings passed to the client library in
2527 commands are now expected to be formatted nickname strings.
2528 If the command does not support the formatted nickname string
2529 it will assume that the sent string is the actual nickname.
2530 Affected file lib/silcclient/command.c.
2532 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Added public key authentication support to OPER and SILCOPER
2535 commands in the client library. Affected file is
2536 lib/silcclient/command.c.
2538 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Changed the get_auth_methdod client operation to be asynchronous.
2541 It can be async if the application resolves the authentication
2542 method from the server during the negotiation. Added new
2543 SilcGetAuthMeth completion callback that the application will
2544 call after resolving the authentication method.
2546 Added function silc_client_request_authentication_method that
2547 the application can use to resolve the authentication method
2548 from the server. Added also SilcConnectionAuthRequest callback
2549 that the library will call after the server has replied. The
2550 application can call this function if it does not know the
2551 current authentication method.
2553 Affected files are lib/silcclient/client.c and
2554 lib/silcclient/silcapi.h.
2556 * The Irssi SILC client now automatically resolves the authentication
2557 method incase any configuration information is not present (and
2558 currently there never is). The affected file is
2559 irssi/src/silc/core/client_ops.c.
2561 * Fixed public key authentication from the client library.
2562 Affected file lib/silcclient/protocol.c. Changed also the
2563 protocol specification about the public key authentication in
2564 the connection authentication protocol. The actual data to be
2565 signed is now computed with a hash function before signing.
2567 * Fixed the public key authentication from the server as well.
2568 Affected file silcd/protocol.c.
2570 * Removed the mlock()'s from the memory allocation routines.
2571 Affected file lib/silcutil/silcmemory.c. The ./configure does
2572 not check anymore for the mlock(). Affected file is
2575 * Fixed USERS command in server to allow the execution of the
2576 command for private and secret channels if the client sending
2577 the command is on the channel. Affected file silcd/command.c.
2579 * Fixed silc_client_get_clients_local to return the clients
2580 count correctly. It could return wrong value. Affected file
2581 lib/silcclient/idlist.c.
2583 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2586 types. The assembler optimizations seemed not to like 64-bit
2587 data types. The assmebler optimizations thus are now enabled
2588 also for BSD systems as opposed to only enable them for Linux.
2590 * Do not check for threads at all on BSD systems. Affected
2591 file configure.in.pre.
2593 * Removed -n and -h options from the Irssi SILC Client since
2594 they are not used in silc.
2596 * Fixed the prime generation to assure that the first digit
2597 of the generated random number is not zero since our conversion
2598 routines does not like number strings that starts with zero
2599 digit. If zero digit is seen the random number is regenerated.
2600 This caused some corrupted RSA keys when the zero first digit
2601 was met. Affected file lib/silcmath/silcprimegen.c.
2603 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Fixed WIN32 configuration in the ./configure script.
2606 Fixed to include xti.h on environments that has it.
2607 Patches by Carsten Ilchmann and andrew.
2609 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Changed the silc_id_create_client_id to be collision
2612 resistant. It is now assured that there cannot be created
2613 two same client ID's. I suspect that some weird bugs in
2614 the server were actually caused by duplicate Client IDs.
2615 Affected file silcd/serverid.[ch]. A router receiving
2616 new ID now also assures and informs the sending server
2617 if the ID caused collision.
2619 * Changed the silc_id_create_channel_id to also assure that
2620 there are no collisions.
2622 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2624 * Statement about ignoring the Mutual Authentication flag when
2625 performing rekey with PFS was a bit misleading. It is ignored
2626 if it was set in the initial negotiation, it cannot be even
2627 set in the rekey. Fixed in the ke-auth draft. Started the
2628 new versions of the protocol drafts in the doc/.
2630 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Fixed a bug in silc_client_command_identify_save when saving
2633 new channel information. The channel name was no duplicated
2634 and caused crash on exit. Affected file is
2635 lib/silcclient/command_reply.c.
2637 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2639 * Fixed the getkey command handling in the server. Send just
2640 empty OK reply to the sender if the key could not be fetched
2641 (but everything else was ok, like the key just was not available).
2642 Changed the public key parameter to optional in the protocol
2643 specs so that empty OK reply can be sent. Affected file
2646 Added a message to Irssi SILC client to tell to user if the
2647 server did not return a public key.
2649 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2651 * Fixed a channel key regeneration bug. It registered new
2652 timeout tasks exponentially until all system resources were
2653 used. Affected file silcd/server.c.
2655 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Added the SILC Document generator to the scripts/silcdoc.
2658 It can be used to generate the Toolkit Reference Manual out
2659 of the source tree. Internally it will also use the RoboDoc
2660 generator now imported in util/robodoc.
2662 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Added couple of return's in rekey protocol if error orccurred
2665 during the protocol. The execution must be terminated.
2666 Affected file silcd/protocol.c. Also, terminate the protocol
2667 always with timeout.
2669 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * The client's Client ID was created initally from the wrong
2672 nickname (it could have been in format nick@host) in the
2673 silc_server_new_client. Affected file silcd/packet_receive.c
2675 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * Added some SILC_LOG_ERROR's to various error conditions
2678 if client could not be added to ID cache. Affected files
2679 silcd/packet_receive.c and silcd/server.c.
2681 * When client's sock->user_data is freed, NULL also the
2682 client->router and client->connection pointers. Added check
2683 for these pointers being NULL to various places around the
2684 code. Affected file silcd/server.c.
2686 * Added client->data.registered == TRUE checks to various
2687 places around the code to assure that unregistered client's
2688 are not handled when it is not allowed. Affected file
2691 * Added `bool registered' fields to all
2692 silc_idlist_[server|client]_get_* routines to indicate whether
2693 the fetched client needs to be registered or not. Affected
2694 file silcd/idlist.[ch].
2696 * Add your own entry as registered to the ID cache in the
2697 server. Affected file server.c.
2699 * Fixed a bug in silc_server_new_server. The SilcServer was
2700 set as the new server's context instead of SilcServerEntry.
2701 This naturally caused some weird bugs.
2703 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2705 * Do not delete the channel rekey task when adding it
2706 for in silc_server_create_channel_key.
2708 * Changed the silc_server_create_channel_key to return
2709 TRUE or FALSE to indicate the success of the channel key
2712 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Fixed MSVC++ project files and added missing files to

2720 does not have it defined. Affected files are
2721 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2723 * Fixed buffer overflow from Irssi SILC Client. Affected
2724 file irssi/src/fe-common/core/themes.c.
2726 * Fixed double free in client library in the file
2727 lib/silcclient/client.c when disconnecting from server.
2729 * Applied double free patch from cras to Irssi SILC client.
2730 Affected files irssi/src/core/[modules/expandos].c
2732 * Fixed the disconnection handling to Irssi SILC Client.
2733 The application must call silc_client_close_connection
2734 in ops->connect client operation in case of failure of
2735 the connection. Affected file is
2736 irssi/src/silc/core/client_ops.c.
2738 * Do not set sock->protocol to NULL in the function
2739 silc_client_close_connection after executing the protocol's
2740 final callback since the sock might not be valid anymore.
2741 Affected file lib/silcclient/client.c.
2743 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Do not enable SILC_THREADS if the linking with libpthread
2746 did not happen. Affected file configure.in.pre.
2748 * Added notion to protocol specification that server must
2749 verify the sent authentication payload with CMODE when
2750 setting the channel founder key. Implemented it to the
2751 server. Affected file silcd/command.c.
2753 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2755 * Added _EXTRA_DIST SILC distribution variable to the
2756 distributions file. It is used to conditionally add extra
2757 files or directories to the specific distribution. Affected
2758 files ./prepare, Makefile.am.pre and distributions.
2760 Removed the `_' from the start of the distribution names.
2763 * Added README.WIN32 for instructions to compile the Toolkit
2766 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Fixed a double free in disconnection in the server. Affected
2769 file is silcd/server.c.
2771 * Fixed the lib/silcske/groups.c to work now also with GMP
2772 MP library. The string conversion did not work when using
2773 specific base and the base is indicated in the string as well.
2775 * Created win32/ directory which now includes MSVC++ specific
2776 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2777 It will appear only in the toolkit distribution
2779 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Changed the key material distribution function in case when
2782 the hash output is too short. The data is now concatenated
2783 a bit differently than it used to. Made the change to the
2784 SKE protocol specification.
2786 * Added better GMP detection to configure.in.pre. A patch
2789 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Fixed a minor bug in SKE that might cause some problem on
2792 some platforms. Affected file lib/silcske/silcske.c.
2794 * Added the cookie checking for initiator in the SKE. It checks
2795 that the responder returns the sent cookie unmodified. The
2796 affected file is lib/silcske/silcske.c. Added new SKE
2797 error type INVALID_COOKIE that can be sent during the
2798 negotiation. Fixed some memory leaks as well.
2800 * Added the "invalid cookie" error message to Irssi SILC client's
2803 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Added `task_max' field to the SilcClientParams to indicate
2806 the maximum tasks the scheduler can handle. If set to zero,
2807 default values are used. Affected file lib/silcclient/silcapi.h.
2809 * Fixed memory leaks in silc_client_close_connection. Affected
2810 file lib/silcclient/client.c.
2812 * Added silc_client_del_client_entry to client library to free
2813 all memory of given client entry. Affected file is
2814 lib/silcclient/idlist.[ch].
2816 * Added new functions silc_client_del_channel and
2817 silc_client_del_server to delete channel and server entries.
2818 Affected file lib/silcclient/[silcapi.h/idlist.c].
2820 * Removed silc_client_del_client_by_id from silcapi.h.
2822 * Fixed the INFO command to return the server's own info
2823 correctly when querying by Server ID. Affected file is
2826 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Removed the non-blocking settings in WIN32 code in the
2829 silc_sock_[read/write] and added SleepEx instead. Affected
2830 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2831 of input data is now checked with FIONREAD and ioctlsocket.
2833 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Call silc_schedule_task_del_by_context in the
2836 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2837 Affected file lib/silccore/silcprotocol.c.
2839 * Call silc_protocol_cancel for active protocols in the
2840 silc_server_close_connection if the funtion
2841 silc_server_free_sock_user_data has not been called.
2842 Affected file silcd/server.c.
2844 * Generic tasks cannot be deleted using the del_by_fd
2845 task deleting function since generic tasks does not match
2846 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2848 * Added a notion to SILCOPER help file that the SILCOPER works
2849 only on router server, not on normal server.
2851 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Added for WIN32 support for the new scheduler as well.
2854 Affected file lib/silcutil/win32/silcwin32schedule.c.
2856 * Fixed the SHA1 implementation to work on various platforms.
2858 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2861 API. It is part of the scheduler now. Everything else is
2862 as previously but some functions has changed their names.
2863 Checkout the lib/silcutil/silcschedule.h for the interface.
2864 Updated all applications to use the new interface. Affected
2865 files are lib/silcutil/silcschedule.[ch].
2867 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * Found a bug in the SKE implementation. The HASH value,
2870 specified by the protocol, was not computed correctly. The
2871 public key of the responder was not added to the computation
2872 even though it is mandatory. Affected file lib/silcske/silcske.c.
2873 This unfortunately causes incompatibilities with older
2874 clients and servers.
2876 * Added WIN32 specific network init and uninit functions:
2877 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2878 the Winsock2. Affected file lib/silcutil/silcnet.h and
2879 lib/silcutil/win32/silcwin32net.c.
2881 * Set the socket always to nonblocking mode on WIN32 after
2882 reading data or writing data. Affected file is
2883 lib/silcutil/win32/silcwin32sockconn.c.
2885 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Fixed various compilation problems under WIN32. Affected
2888 files lib/silcutil/win32/silcwin32thread.c and
2889 lib/silcutil/win32/silcwin32schedule.c.
2891 * Removed all _internal.h #includes from public header
2892 files. Internal headers must never be included from
2895 Removed also the lib/silcske/payload_internal.h file.
2897 * All include files that may be needed (public and some others
2898 included by the public headers) by application developers are
2899 now copied to the ./includes directory. It does not copy any
2900 internal headers. Affected file Makefile.defines.pre and all
2901 Makefile.am's under lib/ and subdirs.
2903 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Do not change the ~/.silc directory's permissions automatically.
2906 Affected file irssi/src/silc/core/clientutil.c.
2908 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Do not cancel the protocol in silc_server_close_connection
2911 it might cause recursion. Now cancelled in the function
2912 silc_server_free_sock_user_data. Affected file silcd/server.c.
2914 * Fixed the silc_server_remove_clients_by_server to regenerate
2915 the channel keys correctly finally. Added also new function
2916 silc_server_remove_clients_channels to actually do it.
2917 Affected file silcd/server.c.
2919 * Fixed the silc_server_new_channel to not crash by giving
2920 wrong router to the new channel. Affected file is
2921 silcd/packet_receive.c.
2923 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2926 which is given as argument to the silc_client_alloc now.
2927 It can be used to configure the client and set various parameters
2928 that affect the function of the client.
2930 * The USERS command in server did not check whether the channel
2931 is private or secret. Affected file silcd/command.c.
2933 * Added new argument to the USERS command in protocol specification.
2934 The USERS command now can take the channel name as argument
2935 as well. Added support for this in client and server and
2936 updated the protocol specs.
2938 * Completed the GETKEY command in client. It can be now used
2939 to fetch also servers public key not only some clients.
2940 Affected files lib/silcclient/command[_reply].c.
2942 * Added silc_client_get_server to return server entry by the
2943 server name. Affected files lib/silcclient/silcapi.h and
2946 * Redefined the IDENTIFY command in protocol specification to be
2947 more generic. It now can be used to query information about
2948 any entity in the SILC Network, including clients, servers and
2949 channels. The query may be based either the entity's name
2950 or the ID. Added support for this in both client and server.
2952 Affected files silcd/command.c and lib/silcclient/command.c
2953 and command_reply.c.
2955 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2956 the _from_client and _from_server functions. Affected file
2959 * Added silc_client_get_channel_by_id_resolve to the file
2960 lib/silcclient/silcapi.h to resolve channel information by
2961 its ID. Added also silc_client_get_channel_by_id that
2962 does not resolve it from the server.
2964 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Added SilcServerEntry context into the client library
2967 to represent one server. The INFO command now allocates
2968 these to save the resolved server info. For now on the
2969 client library will also keep information about servers,
2970 connected and resolved with INFO.
2972 The INFO command now allocates the SilcServerEntry context
2973 and saves the server info there. The COMMAND_REPLY in
2974 the INFO now returns the parameters to application in
2975 same order as defined in the protocol specification.
2977 The entries are cached in the client->server_cache.
2979 * The INFO command is now issued after received the Client ID
2980 from the server. Affected file lib/silcclient/client.c.
2982 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2983 to the application as the mode changer might be server.
2984 It is guaranteed that NULL is not returned anymore to the
2985 application. Affected file lib/silcclient/client_notify.c.
2987 The ID Type is now also passed to the application so that
2988 it can check whether the returned entry is SilcClientEntry
2991 Added new function silc_client_get_server_by_id to return
2992 the server entry by ID. Affected files are the
2993 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2995 * Do not create the channel in the Irssi SILC Client when issuing
2996 the JOIN command but when received the sucessful JOIN command
2997 reply. Otherwise the channel might get created even though we
2998 could not join it. The Affected file is
2999 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3001 * Fixed a channel joining bug in router. The router must also
3002 check the channel modes, invite and ban lists etc. when serving
3003 the JOIN command sent by normal server. Affected file is
3004 silcd/command.c. The router now resolves the client's
3005 information from the server who sent the JOIN command if it
3006 does not know it, and processes the JOIN command only after
3009 * Changed the SilcCommandCb to take new argument; void *context2.
3010 Affected file lib/silccore/silccommand.h
3012 The second argument in the command callbacks in the server now
3013 includes the SilcServerCommandReplyContext if the command was
3014 called as pending command callback from the command reply.
3015 Otherwise it is NULL. When called as pending the status of the
3016 command reply will be checked and if it was erronous the
3017 error will be sent to the original sender of the command.
3018 This way the client always receives the error messages even
3019 though the server was actually the one who received the error
3020 when it resent the command to router, for example. Affected
3021 files silcd/command[_reply].[ch].
3023 * Fixed sending WHOWAS command's error message to client if
3024 the requested client could not be found. It was missing.
3027 * Changed the CMODE and CUMODE commands reply arguments in the
3028 protocol specification. The Channel ID is now sent in both
3029 of the commands to identify the channel. Implemented this
3030 new feature to the client and server. Affected files
3031 lib/silcclient/command_reply.c and silcd/command.c.
3033 * Made better checks for invite and ban lists in the JOIN
3034 command in server. Affected file silcd/command.c.
3036 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * The server now performs the incoming host IP/DNS lookup
3039 using the silc_socket_host_lookup and thus does not block
3040 the server anymore. Affected file silcd/server.c.
3042 * Completed the multi-thread support for SILC Scheduler in
3043 the lib/silcutil/silcschedule.c.
3045 * Fixed the configure.in.pre to detect the pthread correctly
3048 * Fixed a deadlock in silc_task_queue_wakeup in the file
3049 lib/silcutil/silctask.c.
3051 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Added new function silc_schedule_wakeup that is used in
3054 multi-threaded environment to wakeup the main thread's
3055 schduler. It needs to be used when a thread adds a new task
3056 or removes a task from task queues. After waking up, the
3057 scheduler will detect the task queue changes. If threads
3058 support is not compiled in this function has no effect.
3059 Implemented the wakeup mechanism to both Unix and WIN32
3060 systems. Affected files are lib/silcutil/silcschedule.[ch],
3061 lib/silcutil/unix/silcunixschedule.c and the
3062 lib/silcutil/win32/silcwin32schedule.c.
3064 * Added new function silc_task_queue_wakeup to wakeup the
3065 scheduler by the specified task queue. Affected file
3066 lib/silcutil/silctask.[ch].
3068 * The silc_socket_host_lookup_start now wakes up the scheduler
3069 after adding the timeout task. Affected file is
3070 lib/silcutil/silcsockconn.c.
3072 * The silc_socket_host_lookup is synchronous now if the threads
3073 support is not compiled in. However, the callback is still
3074 called asyncronously through the scheduler, anyway. Affected
3075 file lib/silcutil/silcsockconn.c.
3077 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3079 * Added new function silc_socket_host_lookup to perform
3080 asynchronous IP and FQDN lookups for the socket connection.
3081 Affected files lib/silcutil/silcsockconn.[ch].
3083 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3086 that may or may not compile the mutex support in.
3088 Changed the silc_mutex_alloc interface. It allocates the
3089 mutex now to the sent pointer and returns TRUE or FALSE.
3091 Affected file lib/silcutil/silcmutex.h.
3093 * Wrote the SILC Task Queue interface to support multi-threads.
3094 Affected file lib/silcutil/silctask.[ch].
3096 * Wrote the SILC Scheduler to support multi-threads. Affected
3097 file lib/silcutil/silcschedule.c.
3099 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3102 in lib/silcutil/win32/.
3104 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Defined SILC Mutex API and SILC Thread API and implemented
3107 them for Unix. Affected files are
3108 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3109 lib/silcutil/unix/silcunixmutex.c and
3110 lib/silcutil/unix/silcunixthread.c.
3112 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * Fixed the silc_server_remove_clients_by_server's channel
3115 key re-generation. The hash table handling was incorrect
3116 and would not work with many channels. Affected file is
3119 * Fixed some memory leaks around the server code.
3121 * Rewrote the silc_server_get_users_on_channel to support IPv6
3122 based Client ID's. Affected file silcd/server.c.
3124 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3125 specification. However, a separate document must be written
3126 to define the detailed signing procedure and the payload
3127 associated with the flag. Defined the flag to the
3128 lib/silccore/silcchannel.h as well.
3130 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3132 * Changed the dynamic tables to static size tables in the
3133 lib/silccrypt/silchmac.c.
3135 * Removed GCC dependencies from the code. A patch by cras.
3137 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Do not show the error "Error receiving packet bla bla"
3140 in server if it really was not an error (-2 means that reading
3141 is pending). Affected file silcd/server.c.
3143 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Fixed a possible crash in silc_server_remove_clients_by_server
3146 in silcd/server.c. Fixed there also some memory leaks.
3148 * Fixed the silc_idlist_replace_client_id. It could replace
3149 wrong key in the hash table. Affected file silcd/idlist.c.
3151 * Do not check whether there are global users on the channel
3152 if the channel->global_users is FALSE. Affected functions
3153 silc_server_remove_from_one_channel and
3154 silc_server_remove_from_channels in silcd/server.c. Also,
3155 do not check if the removed client is local as we can be
3156 sure that global client was not removed from the channel
3157 and checking for global users is not needed.
3159 * The silc_server_remove_clients_by_server now re-generates
3160 the channel keys correctly for those channels that had
3161 clients removed from them. Affected file silcd/server.c.
3163 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Found the reason of random crashes in the server. We weren't
3166 ignoring the SIGPIPE signal (which can be sent in write())
3167 and it crashed the server. Affected file silcd/silcd.c.
3169 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Assure that sock->user_data is not NULL in the function
3172 silc_server_packet_send in silcd/packet_send.c.
3174 * Disconnect the remote connection if it could not be added
3175 to any ID lists in the server. The affected file is
3178 * Check in silc_server_packet_send[_real/dest] that the
3179 socket is not disconnecting and ignore the data if it is.
3180 Affected file silcd/packet_send.c.
3182 * Define inline to __inline on native WIN32 compilation.
3183 Affected file includes/silcwin32.h.
3185 * Added some explicit type casts for inline code since MSVC
3186 require them. Affected files lib/silcutil/silcbuffer.h,
3187 lib/trq/silcdlist.h and lib/trq/silclist.h.
3189 * Print warning in log files from now on if the packet
3190 decryption fails. Affected file silcd/server.c.
3192 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Changed the `say' client operation's interface to accept
3195 new `type' argument to indicate the type of the message sent
3196 by the library. The application may filter the library's
3197 messages according the type. The affected file is the
3198 lib/silcclient/silcapi.h.
3200 * Added two new functions to lib/silcclient/silcapi.h:
3201 silc_client_del_client and silc_client_del_client_by_id.
3202 Affected file lib/silcclient/idlist.c.
3204 * Moved the clientincludes.h from includes/ to silc/ and
3205 serverincludes.h from includes/ to silcd/.
3207 * The modes for the CMODE and CUMODE are now passed as
3208 uint32 for application with COMMAND_REPLY. The affected
3209 file is lib/silcclient/command_reply.c.
3211 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3213 * /WHOIS without arguments shows client's own information.
3214 Affected file lib/silcclient/command.c.
3216 * Changed PING to not accept any arguments. The specs
3217 says that client can ping only the connected server so
3218 requiring an argument is not needed. Affected file is
3219 lib/silcclient/command.c.
3221 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Fixed a fatal bug in private message sending and reception
3224 encryption and decryption when using private message keys.
3225 The implementation was incorrect and did not follow the
3226 specification. It causd that some of the message were
3227 lost since it did not use the sending and receiving keys
3228 as the protocol suggests. This has been fixed and will cause
3229 incompatibilities with older clients when sending private
3230 message encrypted with private message keys. Affected files
3231 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3232 and various other in Irssi SILC Client.
3234 Added `responder' boolean argument to the functions
3235 silc_client_add_private_message_key[_ske] to indicate when
3236 the key is added as responder or initiator of the key
3239 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Removed the silc_ske_check_version function and created
3242 a SilcSKECheckVersion callback. Added also a function
3243 silc_ske_set_callbacks that is now used to set all SKE
3244 callbacks. The callback functions are not given to
3245 the SKE functions anymore, but this function is used to
3248 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3250 * Added `silc_version' argument to the silc_client_alloc
3251 to define the version of the application for the library.
3252 The library will use the version string to compare it
3253 against the remote host's (usually a server) version
3254 string. Affected file lib/silcclient/silcapi.h
3256 * Added the KE protocol context to Key Agreement context
3257 in client library so that we can abort the SKE if it
3258 is in process when we get timeout. Affected file is
3259 lib/silcclient/client_keyagr.c.
3261 * Do not resolve the client ID forever if it returns in the
3262 first time that such client does not exist. This was done
3263 for example with private message. Affected file is
3264 lib/silcclient/client_prvmsg.c.
3266 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Do not add regex.h for WIN32. The affected file
3269 includes/silcincludes.h.
3271 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3272 not work yet 100%. It generates the DLL's automatically
3273 when compiling with --with-win32 under cygwin.
3275 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * lib/contrib/regex.c is not compiled on WIN32.
3279 * Added silc_net_get_socket_opt function to the
3280 lib/silcutil/silcnet.h.
3282 * Added includes/silcwin32.h for WIN32 specific includes
3285 * Do not use ptime structure or any of the posix process
3286 functions on WIN32 in lib/silccrypt/silrng.c.
3288 * Added silc_gettimeofday to provide generic function
3289 for struct timeval on all platforms. Added the function
3290 to lib/silcutil/silcutil.h.
3292 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3295 library as they clearly belong there. As a plus side we
3296 can make the actual socket connection routines platform
3299 Added also new generic function silc_socket_read and
3300 silc_socket_write (that used to be silc_packet_[read/write].
3301 The implementation of these are platform specific.
3303 * Added WIN32 specific routines of silc_socket_[read/write]
3304 to lib/silcutil/win32/silcwin32sockconn.c.
3306 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Added preliminary support for native WIN32 compilation under
3309 cygwin (using the -mno-cygwin option for GCC) to the
3310 ./configure.in.pre. The --with-win32 now prepares the
3311 compilation for native WIN32.
3313 * Rewrote the SILC Scheduler interface in the file
3314 lib/silcutil/silcschedule.h. The scheduler is now context
3315 based and does not have anymore any global static scheduler.
3316 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3317 and created lib/silcutil/win32 directory for WIN32 based
3320 * Added Unix specific network routines to the
3321 lib/silcutil/unix/silcunixnet.c and the old
3322 lib/silcutil/silcnet.c includes now only generic routines.
3324 Added WIN32 specific network routines to the
3325 lib/silcutil/win32/silcwin32net.c.
3327 * Added Unix specific utility functions from the
3328 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3330 * Added WIN32 SILC Scheduler to the file
3331 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3334 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Do not handle JOIN notify in the server if the target client
3337 is not registered (idata->registered == FALSE). The affected
3338 file is silcd/packet_receive.c.
3340 * Update the nickrec->founder in event_cumode in the Irssi SILC
3341 client. Affected file irssi/src/silc/core/silc-channels.c.
3343 * Fixed the CUMODE_CHANGE notify handling in the server when
3344 server and router are announcing their clients on channels.
3345 Now the mode changes are saved and notified correctly. The
3346 affected file is /silcd/packet_receive.c.
3348 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3349 They really did not replace the cache entry in the ID Cache.
3350 Now they do that. Affected file silcd/idlist.c.
3352 * Fixed the KICK notify handling in the Irssi SILC client to
3353 update the channel records so that the kicked client does not
3354 appear to be on the channel. The affected file is
3355 irssi/src/silc/core/silc-channels.c.
3357 * Always update the conn->current_channel when executing command
3358 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3360 * Fixed the KILL notify handling in Irssi SILC client to remove
3361 the killed client on all channels.
3363 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Fixed the silc_parse_command_line to remove extra spaces
3366 from the start and end of the arguments. Affected file is
3367 lib/silcutil/silcutil.c.
3369 * Cancel and free any active protocol in the function
3370 silc_server_close_connection. Affected file silcd/server.c.
3372 * Cancel and free any active protocol in the function
3373 silc_client_close_connction. Affected file is
3374 lib/silcclient/client.c.
3376 * Do not execute the KILL command for clients that are in
3377 history (ie. they are not in the network). Affected file is
3380 * Fixed KILL notify handling, client does not crash anymore.
3381 Affected file irssi/src/silc/core/silc-channels.c.
3383 * Reduced the default packet buffer size from 2048 to 1024 in
3384 lib/silccore/silcpacket.c.
3386 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3387 counter to the SKE context that is incresed when the SKE library
3388 performs async operation outside the library. If the outside
3389 process frees the SKE context and FREED status will be set
3390 and the library will detect after the sync operation that the
3391 libary is freed. The affected files are
3392 lib/silcske/silcske[_status].[ch].
3394 * Resolve the client entry information in the function
3395 silc_client_channel_message to assure that NULL pointer is not
3396 passed as client entry to the application. */
3398 * Fixed the task timeout calculation to assure that there is
3399 never negative timeouts. The affected file is
3400 lib/silcutil/silcschedule.c.
3402 * Fixed the channel user mode notification sending in server.
3403 It was sent point-to-point to the router (or to server by router)
3404 but it needs to be destined to a channel. The routines now
3405 supports sending the channel user mode notifys to the channels
3406 when announcing clients and channels. Affected files are
3407 silcd/server.c and silcd/packet_receive.c.
3409 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3410 It did not actually replace the old channel entry in the cache.
3411 Affected file lib/silcclient/client_notify.c.
3413 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Fixed a possible crash in silc_packet_send_prepare. It now
3416 assures always that there is enough space in the buffer and
3417 at the tail area of the buffer (for MAC).
3419 Fixed the inbound buffer reallocation in silc_packet_read.
3420 It was old code and did not handle the reallocation correctly.
3423 The affected file is lib/silccore/silcpacket.c.
3425 * Fixed buffer overflow in silc_parse_nickname in the file
3426 lib/silcutil/silcutil.c.
3428 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * make install generates new server keys only if there is not
3433 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3436 Added check that if the NOREPLY is set then we will not send
3437 the away message. This avoids infinite loop of away messages
3438 if both clients are away. The affected file is
3439 lib/silcclient/client_prvmsg.c.
3441 * Fixed client crash if /NICK was given without arguments.
3442 Affected file lib/silcclient/command.c.
3444 * Server does not send the invite list in INVITE command back
3445 to the client if the list was not altered. Added this notion
3446 to the protocol spec as well. Affected file silcd/command.c.
3448 Fixed possible crash in INVITE command by checking the
3449 value of silc_server_get_client_route command.
3451 * Fixed the INVITE notify type handling. The arguments are now
3452 taken in correct order and client does not crash. The affected
3453 file is irssi/src/silc/core/silc-channels.c.
3455 Removed the "Inviting xxx to channel" message from the
3456 client library away and let the application handle it.
3457 Affected file lib/silcclient/command.c. Added that message
3458 to Irssi SILC client's message formats.
3460 * Fixed CMODE command crash in client. It now checks the
3461 amount of arguments correctly and does not crash. The affected
3462 file is lib/silcclient/command.c.
3464 * Do not create new channel automatically in silc_channels_join
3465 but check whether the channel by that name already exists.
3466 Affected file irssi/silc/core/silc-channels.c.
3468 * Do not send the SERVER_SIGNOFF to router if the disconnected
3469 entity was the router. Affected file silcd/server.c.
3471 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3472 SILC client as it was missing from there.
3474 Added the handling of the KICK notify to the Irssi SILC client
3475 as it was missing. Added "you have been kicked" message to
3476 Irssi SILC client's message modules formats.
3478 Added the handing of the KILL notify to the Irssi SILC client
3479 as it was missing. Added the kill message module formats
3482 The affected file is irssi/src/silc/core/silc-channels.c.
3484 * The router did not save the channel mode the server announced.
3485 Affected file silcd/packet_receive.c.
3487 * Fixed a possible crash in INFO command in server. If the
3488 server did not provide the server info it crashed. Affected
3489 file silcd/command.c.
3491 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Fixed the GETKEY command in the server to check also the
3494 global list. Otherwise the GETKEY would not work correctly
3495 in normal SILC server. Affected file silcd/command.c.
3497 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3499 * Fixed GETKEY crash, it crashed if the command did not succseed.
3501 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3504 is now real and not just an macro interface to GMP.
3506 Removed the entire GMP from the source tree and imported new
3507 NSS MPI library instead. Reason for removing GMP is that it is
3508 extremely large and compiles extremely slow. The NSS MPI
3509 is only a few files and compiles in less than 10 seconds.
3510 The speed is also about the same as GMP. The MPI is imported
3511 to lib/silcmath/mpi.
3513 If the system has GMP installed we will still use the GMP.
3514 If it is not then the NSS MPI will be compiled.
3516 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Merged a long nickname (127 characters long) crash bugfix from
3519 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3521 * Merged a freed memory reference bugfix from Irssi CVS tree.
3522 Affected file irssi/src/core/commands.c.
3524 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Added the server's public key sving and verification to the
3527 server when performing the SKE. This was missing and the
3528 remote server's (or router's) public key was accepted without
3529 checking whether we have it previously or trust it at all.
3530 Affected file silcd/protocol.c.
3532 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Check in the silc_server_timeout_remote if protocol is active
3535 and make sure that the protocol's final callback is called so
3536 that all memory if freed. Affected file silcd/server.c.
3538 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * silc_server_whois_send_reply crashed the server if the nickname
3541 was 127 characters long. Affected file silcd/command.c.
3543 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Added sanity check to the silc_server_new_client. If the hostname
3546 is provided inside username then check that the provided hostname
3547 really is the same as the resolved one. If the hostname was not
3548 resolved then check it from the public key. Affected file is
3549 silcd/packet_receive.c.
3551 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3552 if the server disconnected us and the connection is not valid
3553 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3555 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3556 the library to the lib/silcutil/silcutil.[ch].
3558 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Close log file after open. Affected file
3561 lib/silcutil/silclog.c.
3563 * Check whether sock == NULL in silc_client_send_packet and return
3564 if it is. Affected file lib/silcclient/silcclient.c.
3566 * Check rec->entry == NULL in the Irssi SILC Client before
3567 sending the channel message. Affecte file is
3568 irssi/src/silc/core/silc-servers.c.
3570 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Merged a splitted window bugfix from Irssi CVS tree. The
3573 affected file is irssi/src/fe-text/textbuffer-view.c.
3575 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3576 It did not print nickname.
3578 * Improved the distributions system a bit.
3580 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3583 irssi/src/fe-text/gui-window.c.
3585 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3586 to in-active server. The affected file is
3587 irssi/src/silc/core/client_ops.c.
3589 * Resolve the client in USERS command reply if the entry does
3590 not have username resolved. The affected file is
3591 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3592 command to WHOIS command to really resolve stuff. The USERS
3593 is not used any more in any critical section so WHOIS can
3594 be used even though it might be slower than IDENTIFY.
3596 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3599 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Changed the protocol API a bit more consistent in the
3602 lib/silccore/silcprotocol.[ch].
3604 * Changed the following headers to ROBODoc format:
3606 lib/silccore/silcpayload.h
3607 lib/silccore/silcprotocol.h
3608 lib/silccore/silcsockconn.h
3610 All core library headers are now formatted.
3612 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Fixed a bug in Irssi SILC client; do not show that you are
3615 server/router operator if you really are not. Affected file is
3616 irssi/src/silc/core/client_ops.c.
3618 * Renamed silc_command_free_payload to silc_command_payload_free.
3619 Affected file lib/silccore/silccommand.h
3621 * Added silcmath.h to include the prototoypes of various routines
3622 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3625 * Changed the following headers to ROBODoc format:
3627 lib/silccore/silcchannel.h
3628 lib/silccore/silccommand.h
3629 lib/silccore/silcid.h
3630 lib/silccore/silcidcache.h
3631 lib/silccore/silcmode.h
3632 lib/silccore/silcnotify.h
3633 lib/silccore/silcpacket.h
3634 lib/silcmath/silcmath.h
3636 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added checking to the server code not to start the server if
3639 ciphers and stuff are not configured properly. Affected files
3640 silcd/serverconfig.[h] and silcd/server.c.
3642 * Changed the layout of the header files of the public interfaces
3643 in the SILC libraries. The new layout supports ROBODoc
3644 documentation tool (and some others) so that it is easy to create
3645 a library reference manual. All the other headers and source
3646 code must still follow the CodingStyle document. Also source
3647 code must not include these ROBODoc stuffs, only the headers.
3648 Furthermore, all public interface headers must now be named
3649 by using `silc' prefix, example: silcapi.h, silccipher.h.
3650 Some files were renamed due to this. All the other headers
3651 must not be used as public interfaces. I will update the
3652 CodingStyle document later. Changed following headers, so far:
3654 lib/silcclient/silcapi.h
3655 lib/silccore/silcauth.h
3656 lib/silccore/silcprivate.h
3657 lib/silccrypt/silcdh.h
3659 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Removed silc_client_packet_send_flush from the client library
3664 as it is not needed. Affected file lib/silcclient/client.[ch].
3666 * Added printing of message of unresolved authentication method
3667 to the Irssi SILC client. Added it to the module formats.
3668 Removed the same message from the client library.
3670 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added new distribution feature, DISTLABEL. Every distribution
3673 can define own preprocessor label that can be used in the
3674 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3675 file distributions, acconfig.h.pre and prepare.
3677 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Added Makefile.defines_int to include the actual definitions
3680 for Makefile.defines.in. Tested the new distribution system,
3681 created distributions and tested installation.
3683 * Added AWAY message printing to the Irssi SILC client. Added
3684 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3686 * Added SCONNECT command to call the SILC's CONNECT command.
3687 Cannot use CONNECT directly since Irssi uses that internally.
3688 Affected file irssi/src/silc/core/silc-servers.c.
3690 Added ACTION local command. It is same as ME command but takes
3691 the channel as mandatory argument.
3693 Rewrote some of the Irssi's help files to suite for SILC
3696 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Added Makefile.defines[.in] that should for now on be included
3699 in all Makefile.am file in the source tree. That file includes
3700 all common compilation definitions for SILC source tree.
3702 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Minor changes to the ./prepare script to change the package
3705 name according the distribution name to the configure.in.
3707 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3709 * Created new distribution system. Added file `distributions'
3710 that defines all the distributions that can be created out of
3711 the SILC source tree. The ./prepare script now reads that
3712 file to determine how to prepare the distributions. The
3713 first argument to the ./prepare is the name of the distribution
3714 and second is the version of the distribution. If given
3715 without arguments it creates the default (toolkit) distribution
3716 with the default version (defined in ./prepare).
3718 All Makefile.am files that are subject to the distributions
3719 are now named as Makefile.am.pre. These are ./Makefile.am
3720 and lib/Makefile.am. Others may be changed later.
3722 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Added invite list, ban list, some key management and connection
3725 error message printing to module formats in the Irssi SILC client.
3727 * Added new silc_client_set_away_message to set the away message
3728 that is back to the person who sent private message. The
3729 affected file lib/silcclient/silcapi.h and the
3730 lib/silcclient/client_prvmsg.c.
3732 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Fixed the private message sending in the Irssi SILC client,
3735 added local command KEY to the Irssi SILC client.
3737 Added key management and key agreement message formats to the
3738 irssi/src/fe-common/silc/module-formats.[ch].
3740 Added USERS (alias WHO) printing, server/router operator
3741 indication and LIST command printing to the module formats.
3743 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Fixed channel joining notify handling, cumode notify handling
3746 from Irssi SILC client.
3748 * Added SILC specific module-formats to the Irssi SILC client so
3749 that SILC specific message hilighting, colors etc is possible.
3750 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3752 Added channel mode, channel user mode, actions, notices,
3753 whois and whowas printing to the the module-formats.c.
3755 * Fixed a bug in channel deletion in the server. The channel
3756 is not left to the cache even if the channel founder auth mode
3757 is set when there are no users anymore on the channel. Affected
3758 file silcd/server.c.
3760 * The silc_net_localhost now resolves the entire hostname including
3761 the domain name. Affected file lib/silcutil/silcnet.c.
3763 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Changed the ask_passphrase client operation to be ascynchronous.
3766 It has now a completion callback and a context that the
3767 application must call after it has got the passphrase from
3768 the user. Affected files lib/silcclient/silcapi.h,
3769 lib/silcclient/protocol.c, lib/silcclient/command.c and
3772 Added SilcAskPassphrase callback that the application calls
3773 to deliver the passphrase to the library.
3775 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3776 The public key verification and especially a certificate
3777 verification is asynchronous procedure.
3779 Added new SILC_SKE_STATUS_PENDING status to indicate the
3780 request is pending and a callback will be called to finalize
3783 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3784 indicate that remote end did not send its public key (or
3785 certificate), even though we require it. Added check for this
3786 condition in the SKE. This was a security bug, now fixed.
3788 Defined new SilcSKEVerifyCbCompletion callback that is called
3789 when the verification process is completed.
3791 The affected files lib/silcske/silcske_status.h and
3792 lib/silcske/silcske.[ch].
3794 * Changed the verify_public_key client operation to be async
3795 as well. Defined SilcVerifyPublicKey callback that is used to
3796 indicate the success of the public key verification process.
3798 Changed the server and client to use the new async client
3801 * Changed the Irssi SILC client's internal scheduler to be called
3802 twice as many times as it used to be. As a result the client
3803 should be a bit faster now. Affected file is
3804 irssi/src/silc/core/silc-core.c.
3806 * Added support to Irssi SILC client of asynchronous public key
3807 verification and passphrase inquiry. Affected file is
3808 irssi/src/silc/core/silc-core.c.
3810 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Do not say "You have left channel %s" in client library.
3813 Moved it to the application. Affected files are
3814 lib/silcclient/command.c and silc/client_ops.c.
3816 * Fixed silc_client_get_clients. Command context was not
3817 duplicated and was freed memory in the callback. Affected
3818 file lib/silcclient/idlist.c.
3820 * Do not say "you are now talking..." on JOIN command in the
3821 client library. The appliation must handle it.
3823 * Do not say ".. changed topic to" in command reply in the
3824 client libary. The application must handle it.
3826 * Fixed TOPIC command sending in the client library.
3828 * Fixed a memory leak in silc_client_command_free in the file
3829 lib/silcclient/command.c.
3831 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Imported a modified version of Irssi client to the source tree.
3834 The Irssi will be used to create a new client called
3835 Irssi SILC. Imported to irssi/.
3837 Added silc_core_init_finish function to the Irssi. Affected
3838 file irssi/configure.in.
3840 A lot changes in the Makefile.ams around the irssi tree.
3842 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3844 * Do not rehash if the new size is same as the old size of the
3845 hash table, in the silc_hash_table_rehash*. The affected file
3846 lib/silcutil/silchashtable.c.
3848 * Replaced hash_table_del_by_context calls from the server
3849 (when channel->user_list and client->channels) to the
3850 hash_table_del as it is sufficient and faster.
3852 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Added silc_hash_table_list, silc_hash_table_get and the
3855 SilcHashTableList structure to provide an alternative way to
3856 traverse the hash table. The affected files are
3857 lib/silcutil/silchashtable.[ch].
3859 * Changed the server's idlist routines to use the hash table
3860 routines to optimize the code.
3862 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Replaced the client entry's `channel' list and channel entry's
3865 `user_list' list to hash tables for optimized lookup. Changed
3866 the code to use the hash table interface around the code.
3867 Affected file lib/silcd/idlist.[ch].
3869 * Added `auto_rehash' boolean argument to the function
3870 silc_hash_table_alloc to indicate whether the hash table should
3871 auto-rehash when it thinks is appropriate time. It will
3872 increase the hash table size if the there is twice as much
3873 entries in the table than the size of the table, and will
3874 decrease the size if there are twice as less entries than
3875 the size of the table.
3877 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3881 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * silc_idcache_purge_by_context deletes the entry now by context
3884 as it is supposed to do. Affected file lib/silccore/idcache.c.
3886 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3887 client is not anymore valid (WHOWAS givens the info) and not
3888 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3890 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Removed the `data' and `data_len' arguments from the ID Cache
3893 interfaces and added `name' argument. ID Cache does not handle
3894 anymore the binary data only a names associated with given ID.
3896 * When hashing a Client ID with silc_hash_id the entire ID is
3897 not hashed anymore, instead only the hash of the Client ID is
3898 hashed. This way we can access the Client ID from the cache
3899 with Client ID but with the hash of the ID (which is a hash of
3900 the nickname) as well without any difference in performance.
3902 Added also silc_idcache_find_by_id_one_ext to do one on one
3903 searching when we have the actual ID. Added also function
3904 silc_hash_client_id_compare. The affected files are
3905 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3907 * When hashing the name associated with a ID it is always done
3908 in lowercase. This way we can access the cache without worrying
3909 about case-sensitivity, even though, for example nicknames are
3912 * Fixed a bug in server with channel message sending. It put
3913 wrong ID type as destination ID. The affected file
3914 silcd/packet_send.c.
3916 * silc_idcache_del_by_context now deletes from all hash tables
3917 by context. Affected file lib/silccore/idcache.c.
3919 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Changed the client library to use the new ID Cache interface.
3922 Changes around the source tree.
3924 * Added silc_hash_table_rehash_ext to rehash with specific
3925 hash function. Affected file lib/silcutil/silchashtable.[ch].
3927 * Added silc_hash_string_compare to compare two strings in the
3928 hash table. Affected file lib/silcutil/silcutil.[ch].
3930 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Added new function silc_idcache_del_by_context into the
3933 lib/silccore/idcache.[ch].
3935 * Changed the server's ID list routines to use the new ID Cache
3936 interface. Changes around the source tree.
3938 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added silc_hash_table_del[_by_context]_ext functions in to the
3941 lib/silcutil/silchashtable.[ch].
3943 Removed silc_hash_table_find_all* routines and added new
3944 silc_hash_table_find_foreach to replace them.
3946 Added silc_hash_table_replace_ext function as extended
3947 replacing function. Separated the simple hash table interface
3948 from the extended hash table interface in the file
3949 lib/silcutil/silchashtable.h.
3951 * Fixed minor bugs and changed it to use some of the new
3952 hash table functions in lib/silccore/idcache.c
3954 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added new function silc_hash_table_find_all to return all keys
3957 in the hash table by the specified key. As the hash table is
3958 collision resistant it also makes it possible to have several
3959 duplicate keys in the hash table. This function may be used to
3960 find all of the keys from the hash.
3962 Added user_context arguments to the SilcHashFunction,
3963 SilcHashCompare and SilcHashDestructor to deliver user specified
3966 Added new fuctions silc_hash_table_find[_all]_ext to do
3967 extended lookup with specified hash and compare functions and
3968 specified user contexts.
3970 Added new function silc_hash_table_add_ext to add the key
3971 with specified hash function and user context.
3973 Added new function silc_hash_table_foreach to traverse all
3974 entrys in the hash table. Added SilcHashForeach callback
3977 Added new function silc_hash_table_del_by_context to delete
3978 the entry only if the context associated with the key matches.
3980 Affected files are lib/silcutil/silchashtable.[ch].
3982 * Removed silc_hash_[server/client/channel]_id and added just
3983 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3984 silc_hash_id_compare to compare two ID's using as the hash table
3985 comparison function. Added also silc_hash_data to hash
3986 binary data and silc_hash_data_compare to compare it.
3988 * Removed silc_idlist_find_client_by_hash as it is not needed
3989 anymore. Affected file silcd/idlist.[ch].
3991 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3992 to use internally the SilcHashTable. The new ID Cache is a lot
3993 faster than the old one. Some of the ID Cache interface was also
3994 rewritten and obsolete and stupid functions were removed.
3996 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Added entry_count field to the SilcHashTable to keep the number
3999 of the entries in the table. Implemented the function
4000 silc_hash_table_rehash. Added new function
4001 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4003 Fixed a minor bug in silc_hash_table_free.
4005 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4006 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4007 into the lib/silcutil/silcutil.[ch].
4009 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Implemented a collision resistant hash table into the
4012 lib/silcutil/silchashtable[ch]. See the header and the source
4013 for the SilcHashTable API.
4015 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Merged dotconf version 1.0.2 into lib/dotconf.
4019 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Do not compile anything in lib/silcsim/* if the SIM support
4022 is not enabled. The tree should now compile without problems
4025 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Compiled the SILC under cygwin. Compiled and tested briefly
4028 without problems. More tests needed. The SIMs didn't compile
4031 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4033 * Fixed possible crash in silc_get_username in the
4034 lib/silcutil/silcutil.c.
4036 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Fixed a va_arg in silc/client_ops.c.
4040 * Oops, RC5 routines were named AES and caused some problems
4041 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4043 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Added new SilcIDIP structure into the lib/silccore/id.h and
4046 replaced the old `ip' fields from all SILC ID's to that type.
4047 This is a step towards IPv6 support.
4049 The silc_id_get_len takes now the ID as an extra argument.
4050 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4051 both IPv4 and IPv6 based ID's.
4053 The affected files are lib/silccore/id.[ch] and other files
4054 around the tree using these routines.
4056 * Removed the ID length arguments in server from various
4057 silc_server_send_notify_* routines -> they are not needed
4060 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Fixed memory leak in silc_encode_pem_file in the file
4063 lib/silcutil/silcutil.c.
4065 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Check minor version as well in the SKE. Affected files are
4068 silcd/protocol.c and lib/silcclient/protocol.c.
4070 * Added --identifier option to the server so that an identifier
4071 can be when creating the public key for the server. Affected
4072 file is silcd/silcd.c.
4074 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4075 lib/silccrypt/silcpkcs.c.
4077 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Register default ciphers and stuff when using -C option with
4080 the server. Affected file sildc/silcd.c.
4082 * Put back the servers public key filename format, it is better
4083 than the new one. For now, the client keys are saved with the
4084 new filename format. The affected file silc/client_ops.c.
4086 * Implemented the Cipher API for the rest of the ciphers that
4087 did not implement it or implemented it the wrong way.
4089 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Register default ciphers and stuff when using the -S option
4092 in the client. Affected file silc/silc.c. Same also when
4093 creating new key pair with -C option.
4095 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Fixed the silc_verify_public_key client operation function to
4098 save the public keys differently. The fingerprint is now
4099 used as filename and not the hostname. This way also the
4100 client keys are saved uniquely and not with hostnames. The
4101 affected file is silc/client_ops.c.
4103 * Trimmed the silc_hash_fingerprint function to remove extra
4104 whitespaces from the end of the fingerprint. The affected
4105 file is lib/silccrypt/silchash.c.
4109 * Added silc_cipher_register_default function to register all
4110 default ciphers. It can be used when configuration files
4111 does not exist and the application does not want any specific
4112 ciphers in any specific order.
4114 The SilcDList is now used as silc_cipher_list dynamically
4115 allocated cipher list. Removed the static list all together
4116 and now all ciphers must be allocated to the dynamic list.
4117 The silc_cipher_alloc routine was changed to check only the
4120 All silc_cipher_* routines that used to return int returns
4123 The affected files lib/silccrypt/silccrypt.[ch].
4125 * The same thing was done to silc_hash_* as for silc_cipher_*
4126 routines. Affected files lib/silccrypt/silchash.[ch].
4128 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4129 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4130 Added also silc_pkcs_[un]register[_default] functions.
4131 Removed the data_context from the PKCS API.
4133 * Added silc_hmac_register_default function to register default
4134 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4135 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4136 to unregister all hmacs at once.
4138 * Register the default ciphers, hash functions, PKCSs and HMACs
4139 if client's configuration file does not exist. The affected
4142 * The client did not load the hash functions from the SIM
4143 modules at all. Added support for this. Affected file is
4144 silc/clientconfig.c.
4146 * When decoding public key with silc_pkcs_public_key_decode, check
4147 the supported algorithm only if PKCS are registered. Affected
4148 file lib/silccrypt/silcpkcs.c. The same was done with the
4149 silc_pkcs_private_key_decode.
4151 * Fixed the SILC List routines to keep the list always in order.
4152 It used to change the list's order when traversing the list but
4153 not it preserves the order. Affected file lib/trq/silclist.h.
4155 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Added the client library to use the SilcSocketConnection's
4158 reference counter (by silc_socket_dup) to prevent the bug that
4159 the socket object may be freed underneath async operation.
4161 * The name resolv library checking fixes in the configure.in.pre.
4164 * Created new version of the protocol drafts for future
4165 development. The -03 drafts are the ones that will be changed
4166 in the trunk now and the -02 will remain as they are.
4168 * Send list of CUMODE notifys to the router when announcing
4169 the channel users to the router. Affected file silcd/server.c.
4170 If the router receiving channel founder CUMODE for a channel
4171 that already has channel founder it will send CUMODE notify
4172 to the sender to remove the channel founder rights from the
4173 announced client. Affected file silcd/packet_receive.c.
4175 * The CUMODE notify may now use Server ID as well as the entity
4176 who changes the mode. Updated protocool specs.
4178 * Updated INSTALL and README files.
4180 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * New web pages in the http://silc.pspt.fi. The pages was
4187 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Implemented the [DenyConnectin] config section in the server.
4190 Added silc_server_config_denied_conn to check whether incoming
4191 connection is denied. Affected file silcd/serverconfig.[ch].
4193 * Do not check the ports when checking the incoming configuration
4194 data if the port is 0, meaning any. Affected file is
4195 silcd/serverconfig.c.
4197 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Fixed buffer overflow in silc_string_compare in the file
4200 lib/silcutil/silcutil.c.
4202 * Fixed double free in silc_server_command_leave in the file
4205 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Fixed the version checking in the server. Affected file is
4210 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Fixed the configuration data fetching when accepting new
4213 connections in the server. Affected file silcd/server.c.
4215 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Added `sender_entry' argument to the function
4218 silc_server_packet_relay_to_channel so that we can check
4219 whether some destination actually belongs to the same route
4220 the sender belongs (ie, we must not resend the packet to the
4221 sender). Affected file silcd/packet_send.[ch].
4223 * Added `servername' field to the SilcClientEntry in the server
4224 to hold the name of the server where client is from. Affected
4225 file is silcd/idlist.h.
4227 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Moved the channel message encrypting in the router betwen
4230 router connections from silc_server_channel_message to the
4231 silc_server_packet_relay_to_channel since we want to check
4232 whether we have anybody channel before encrypting anything.
4233 Affected files silcd/packet_[receive/send].c.
4235 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Fixed the [AdminConnection] server config section to support
4238 multiple entries. Affected file silcd/serverconfig.c.
4240 * Added support into the server to check the validity of the
4241 incoming connection before executing any KE or authentication
4244 * The connection configuration is now saved to the KE and
4245 connection auth protocol contexts and not fetched anymore in
4246 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4248 * The local hosts listenning address and port is also resolved
4249 now when starting the server. We want to have the socket object
4250 to include the real address and port for the listener. Added
4251 new function silc_net_check_local_by_sock into the files
4252 lib/silcutil/silcnet.[ch].
4254 * Fixed a broadcast bug in server -> do not broadcast if we
4257 * Fixed a routing bug. Do not route broadcast packets ever.
4258 Broadcast packets must be processed always and not routed since
4259 they may be destined to some other host than yourself and thus
4260 would get routed without no good reason. Affected file is
4263 * Added function silc_server_config_is_primary_route to check
4264 whether primary router connection has been configured (a router
4265 configuration that we are initiating). If there is not, we
4266 will assume that there is only two routers in the SILC network
4267 and we will use the incoming router connection as our primary
4268 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4270 * Changed the order of the broadcasting. Broadcast _after_ the
4271 packet has been processed not before. Affected file is
4274 * Fixed a [ClientConnection] parsing bug. The port was never
4275 parsed correctly thus resulting to port 0. Affected file
4276 silcd/serverconfig.c.
4278 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4279 argument and did not set the broadcast packet flag. Affected
4280 file silcd/packet_send.c. Fixed same bug in the function
4281 silc_server_send_notify as well.
4283 * If we receive NEW_ID packet for our own ID in the server, ignore
4286 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Removed the nickname from the Private Message Payload.
4291 Updated the code and the protocol specs.
4293 * Updated protocol specs for submitting to the IETF.
4295 * Tweaked the Random Number Generator a bit. Affected file
4296 lib/silccrypt/silcrng.c. Exported a new function
4297 silc_rng_[global]_add_noise which can be used to add more
4300 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Do not parse packets with different timeout when protocol
4303 is active -> may cause problem with rekey. Affected file
4306 * When server receives signoff notify it must not create
4307 new channel key if the client is on any channels since the
4308 sender of the signoff notify will create it.
4310 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added printing of error messages during SKE protocol from the
4313 failure packet sent by server during SKE. Affected file
4316 * Removed the client's failure_callback handling with timeout
4317 and handle it immediately when received.
4319 * The SKE library returned wrong type in SUCCESS and FAILURE
4320 packets. They must be 32 bit MSB not 16 bit MSB.
4322 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Ok, rewrote the logic of the re-key and now it seems to work.
4325 I tested it on high traffic with frequent re-keys without
4326 problems. Added hmac_receive (and renamed hmac to hmac_send)
4327 in SilcClientConnection in lib/silcclient/client.h and
4328 in SilcIDListData in silcd/idlist.h. Also, removed the
4329 SilcPacketParserContext's cipher and hmac fields as they are
4330 not needed anymore and actually caused some problems when
4331 the ciphers and hmac's changed underneath the packet parser.
4333 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * If re-key protocol is active then process the incoming packets
4336 synchronously since we must assure that icoming packets encrypted
4337 with the old key is processed before the new keys is set to
4338 use. This is true other packets than for REKEY packets.
4339 Affected file silcd/server.c. The same was done to client library
4340 as well, affected file lib/silcclient/client.c.
4342 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Fixed bug in client and server to accept the force send if
4345 the packet is send from silc_[server/client]_packet_process
4346 function. Otherwise the packets are never delivered, oops.
4348 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Disable force sending of packets when REKEY protocol is active.
4351 We must assure that no packet is sent directly when rekey is
4352 performed. All packets must be sent through packet queue.
4353 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4354 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4355 function is silc_[server/client]_packet_send_real to check
4358 * Replaced the SIM paths from example config files to
4359 /usr/local/modules. Also, make install creates now
4360 /usr/local/silc/logs directory to hold all the SILC server
4363 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Made the configure.in.pre work on Solaris. Patch by salo.
4367 * Made all ciphers compatible with non-x86 machines. Defined
4368 CBC mode macros into lib/silccrypt/ciphers_def.h.
4370 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Fixed the make install.
4374 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * When MAC computation fails the silc_packet_decrypt returned 0
4377 even though it was supposed to return -1. Fixed this. The
4378 affected file is lib/silccore/silcpacket.c.
4380 * Do not replace the config files in /etc/silc (in make install)
4381 if they already exist. Affected file ./Makefile.am.
4383 * Do not send re-key packets immediately but through packet queue.
4384 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4386 * Changed silc_net_check_host_by_sock to return FALSE if the
4387 IP/DNS could not be resolved. Though, it returns the IP address
4388 now even if it could not resolve it (but returns also FALSE).
4389 Affected file lib/silcutil/silcnet.[ch].
4391 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added silc_pkcs_decode_identifier to decode the public key's
4394 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4395 Added also silc_pkcs_free_identifier. Added also new context
4396 SilcPublicKeyIdentifier.
4398 * Added -S option to the silc client. It is used to dump the
4399 contents of the specified public key file.
4401 * Changed the PKCS api to return the public key length when
4402 setting the public key.
4404 * Fixed a fatal bug in the public and private key file loading.
4405 Affected file lib/silccrypt/silcpkcs.c.
4407 * Execute the packet parsing for client with zero (0) timeout
4408 if the protocol is active. Affected file silcd/server.c.
4410 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Made the key generation options to the silcd program. Added
4413 -C option, equivalent to client's option.
4415 * Added new [ServerKeys] config section to the server. It
4416 configures the server's public and private key.
4418 * Defined generic Public Key Payload into the protocol
4419 specification to send specific type of public keys and
4422 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4423 public key or certificate.
4425 * Implemented the GETKEY command to the server and to the
4426 client library and on user interface.
4428 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Made preliminary `make install' work.
4432 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added SilcServerRekey context into silcd/idlist.h.
4436 * Added the PFS support as defined in the specification to the
4437 SKE protocol. Affected files lib/silcske/*.c.
4439 * Added `ske_group' field to the SilcServerRekey context to hold
4440 the number of the SKE group that is used with PFS in re-key.
4441 Affected file silcd/idlist.h.
4443 * Added PFS re-key support to the server. Affected file is
4446 * Added silc_protocol_cancel to cancel execution of the next
4447 state of the protocol. Affected file is
4448 lib/silccore/silcprotocol.[ch].
4450 * Added the re-key support with and without PFS to the client
4451 library. Re-key is performed once in an hour, by default.
4453 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4454 Added silc_client_rekey_callback and silc_client_rekey_final.
4455 Affected files are lib/silcclient/protocol.[ch] and
4456 lib/silcclient/client.[ch].
4458 * Removed the `hmac_key' and `hmac_key_len' fields from the
4459 SilcClientConnection structure; not needed. Affected file is
4460 lib/silcclient/client.h.
4464 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Do not ask whether user wants to use the negotiated private key
4467 for private messages, just use it. Affected file is
4468 silc/local_command.c.
4470 * Added `send_enc_key' and `enc_key_len' fields to the
4471 SilcIDListData structure since they are needed in the re-key
4472 phase. Affected file is silcd/idlist.[ch].
4474 * Implemented the simple re-key protocol into the server.
4475 Affected files silcd/server.c and silcd/protocol.[ch]. The
4476 re-key will be performed once in an hour, by default.
4478 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4479 Added silc_server_rekey, silc_server_rekey_callback and
4480 silc_server_rekey_final.
4482 * Removed Tunneled flag from the protocol. Updated the code
4483 and the specifications.
4485 * Adde `pfs' field to the SilcIDListData to indicate whether
4486 the PFS is to be performed in the re-key. Affected file is
4489 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4492 int64 of at least the xintXX size. If void * is less that 4
4493 bytes uint32 * will be used. Defined bool as boolean.
4495 * Changed _ALL_ unsigned long and unsigned int to uint32,
4496 unsgined short to uint16 in the source tree.
4498 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4499 not handle clients that has entry->data.registered == FALSE.
4500 They are not in the network anymore. Affected file is
4503 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Implemented the sending of the SERVER_SIGNOFF notify in the
4506 server. Affected file is silcd/server.c.
4508 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4509 Added also silc_notify_payload_encode_args into the
4510 lib/silccore/silcnotify.[ch].
4512 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4513 Affected file silcd/packet_receive.c.
4515 * Implemented the SERVER_SIGNOFF notify handling in the client
4516 library. Affected file lib/silcclient/client_notify.c. Also,
4517 implemnted the printing of the SERVER_SIGNOFF info to the
4518 application. Affected file silc/client_ops.c.
4520 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4521 if the deleting was successful. Affected file silcd/idlist.[ch].
4523 * Added support for public key authentication in the connection
4524 authentication protocol in the client library. Affected file
4525 lib/silcclient/protocol.c.
4527 * Changed the server's silc_idlist_get_clients_by_* interface
4528 to support already allocated array so that new entries may be
4529 added to pre-allocated array. Affected file silcd/idlist.[ch].
4530 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4531 and command replies.
4533 * All command reply functions in the server now calls the
4534 pending command callback even if error occured. This way the
4535 error will be delivered to the client as well. Affected files
4536 silcd/command.c and silcd/command_reply.c.
4538 * Fixed INFO command to return local server's info if no server
4539 was provided. Affected file lib/silcclient/command.c.
4541 * Removed RESTART command for good. Updated the code and the
4544 * Rewrote parts of the task system. It is a bit simpler now.
4545 Removed unsued task priorities. The affected files are
4546 lib/silcutil/silctask.[ch].
4548 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Moved the USERS printing from the library to the application.
4551 Affected files lib/silcclient/command.c and silc/client_ops.c.
4553 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Added channel key re-key support. The re-key is perfomed
4558 only by the router and is done once in an hour. Added `rekey'
4559 field to the SilcChannelEntry in the server. Affected files
4560 silcd/server.c and silcd/idlist.h.
4562 * Added silc_task_unregister_by_context into the file
4563 lib/silcutil/silctask.[ch].
4565 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added SILC_UMODE_GONE mode to indicate when the client is not
4568 present in the SILC network. Added also support to the local
4569 command AWAY that will set this mode. Added support of showing
4570 "xxx is gone" in WHOIS command. The USERS command shows the
4571 gone status as well.
4573 * Fixed setting server and router operator privileges in the
4574 server's UMODE command. Affected file silcd/command.c.
4576 * Merged the SKE KE1 and KE2 payloads into one payload. The
4577 new KE payload is equivalent to the old KE2 payload.
4579 Cleaned up the SKE Start Payload parsing. It now uses the
4580 simple buffer unformatting to do the parsing. A lot faster
4583 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4584 to the SKE that is used to indicate whether both of the SKE
4585 parties should perform authentication. By default only the
4586 responder performs authentication. By setting this flag also
4587 the initiator must do authentication. By default it is unset
4588 since in normal SKE case, client to server connection, only
4589 the responder should do authentication. When doing SKE between
4590 two clients both should perform authentication. Updated the
4591 code and the protocol specs.
4593 * A little fix to IDENTIFY command in the server. Search the
4594 client first by hash not nickname. Affected file is
4597 * Fixed the silc_client_close_connection to support closing
4598 the client to client connections wihtout deleting too much
4599 data. Affected file lib/silcclient/client.c.
4601 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4602 are received if protocol used to be active but is not anymore
4603 the application would crash due to NULL pointer dereference.
4604 Affected files silcd/server.c and lib/silcclient/client.c.
4606 * Added `hash' field to the SilcClientConnection to include
4607 the hash function negotiated in the SKE protocol.
4609 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4610 to set the channel founder authentication data. A client can
4611 claim the founder rights later by providing the authentication
4612 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4613 This way the channel founder can regain the channel founder
4614 privileges even it is left the channel. This works only on
4615 local server and the client must be connected to the same
4616 server to be able to regain the founder rights. Updated the
4617 protocol specs accordingly.
4619 Added support to the CMODE command in the client to set the
4620 founder auth data. Read the README to see how to set it.
4622 Added support to the CUMODE command to claim the founder
4623 rights. Read the README to see how to do it.
4625 Added support for the founder authentication to the Channel
4626 Entry in the server. Affected file silcd/idlist.h.
4628 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4629 server's CMODE command. Affected file silcd/command.c.
4631 * Added the following new functions into lib/silccore/silcauth.[ch]:
4632 silc_auth_get_method and silc_auth_get_data.
4634 * The server now saves the remote hosts public key to the
4635 SilcIDListData pointer. Affected file silcd/protocol.c.
4637 * The normal server now does not remove the channel entry from
4638 the cache if the founder authentication data is set. It used
4639 to remove it if the founder was the last one on the channel on
4640 the server and left the channel. The auth data is saved and
4641 if the channel is re-joined later the old entry is used with
4642 the old auth data. Affected files silcd/command_reply.c and
4645 * Removed the `pkcs' field from the SilcIDListData structure
4646 in the server; it is not used. Affected file silcd/idlist.h.
4648 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Fixed packet processing on slow links. Partial packets were
4651 never re-processed because the incoming data buffer was cleared
4652 by the application. Application must not directly clear the
4653 sock->inbuf, the packet processing routines handle it. Fixed
4654 this in client library and in server.
4656 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Fixed the WHOIS and IDENTIFY send reply function to really
4659 check whether to send list or just one entry. Affected file
4662 * Cleaned up the LEAVE command's channel key distribution. The
4663 affected file silcd/command.c.
4665 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4666 can enforce the channel mode as well. In that case the ID
4667 includes the ID of the server. The code now enforces the
4668 mode change if the router have different mode than the server.
4670 * The notify client operation with CMODE_CHANGE notify can now
4671 return NULL client_entry pointer if the CMODE was not changed
4672 by client. Application must check for this.
4674 * Added <Server ID> argument to INFO command to support server
4675 info fetching by Server ID.
4677 * Added silc_server_announce_get_channel_users to get assembled
4678 packets of channel users of the specified channel. Affected
4679 file silcd/server.[ch].
4681 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4682 was freed underneath the ID Cache.
4684 * Re-announce clients when the server received CHANNEL_CHANGE
4685 notify from the router. Affected file silcd/packet_send.c.
4687 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4690 crashed since it did not handle the fact that there is no cipher
4691 called "3" and didn't check the error condition. Now fixed.
4693 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4694 flag. It can be used to send message requests.
4696 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Implemented the RESTART command in the client.
4700 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4701 notice type messages. Added notice printing to the user
4704 * The channel keys are not re-generated if the channel's mode
4705 is PRIVKEY, ie private key on the channel exists. Affected
4706 files silcd/server.c and silcd/command.c.
4708 * Fixed a little bug in channel message delivery when channel
4709 private keys are set in the server. Affected file is
4710 silcd/packet_send.c.
4712 * Changed the setting on channel->on_channel = TRUE from the
4713 silc_client_save_channel_key to the JOIN command reply. The
4714 key payload is not received if the private channel key is set.
4715 Affected file lib/silcclient/command_reply.c and the
4716 lib/silcclient/client_channel.c.
4718 * When the CMODE_CHANGE notify is sent and the channel private
4719 key mode is removed the channel key must be re-generated in
4720 other cells as well. Added this support for the router in the
4721 silcd/packet_receive.c.
4723 * Added new local command NOTICE to send notice message on
4724 channel. Affected file silc/local_command.[ch].
4726 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4728 * Added new local command ME to the client. It is used to send
4729 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4730 some action. Affected file silc/local_command.[ch].
4732 * Changed channel_message and private_message client operations
4733 to deliver the message flags to the application. Added also
4734 the `flags' arguments to the silc_client_send_channel_message
4735 and silc_client_send_private_message functions. Affected file
4738 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Redefined the Private Message Payload to support private message
4741 keys and to support the new private message flags. Updated
4742 the protocol specs. Flags makes it possible to have for example
4743 CTCP style messages.
4745 * Added new type SilcPrivateMessagePayload and defined an API
4746 for it in the lib/silcclient/silcprivate.[ch].
4748 * Tested private message private keys successfully. Tested the
4749 private message key set, unset and list commands with the new
4752 * Redefined the Channel Message Payload to include the channel
4753 message flags (equal with private message flags) to support
4754 for example CTCP style messages.
4756 * Defined some of the message (for channel and private message)
4757 flags. Updated the protocol specs and added the flags to the
4758 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4760 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Added SilcKeyAgreementStatus type to the key agreement routines
4763 to indicate the current status and error if one occured.
4764 The status types are defined in the lib/silcclient/silcapi.h.
4766 * Added new local command KEY that is used to set and unset private
4767 keys for channels, set and unset private keys for private messages
4768 with remote clients and to send key agreement requests and
4769 negotiate the key agreement protocol with remote client. The
4770 key agreement is supported only to negotiate private message keys,
4771 it currently cannot be used to negotiate private keys for channels,
4772 as it is not convenient for that purpose.
4774 * Fixed a minor pending callback setting bug in the function
4775 silc_client_get_client_by_id_resolve, now the function works.
4776 Affected file lib/silcclient/idlist.c.
4778 * Added function silc_net_get_local_port to get local bound
4779 port by socket. Added to lib/silcutil/silcnet.[ch].
4781 * Added `sockets' and `sockets_count' fields to the SilcClient
4782 object. They hold the sockets of the listenning sockets in
4783 the client. Listenning sockets may be for example the key
4784 agreement server. Affected file lib/silcclient/client.[ch].
4785 Added functions the silc_client_add_socket and the
4786 silc_client_del_socket. They are exported to the application
4789 * Added ~./silc/clientkeys to support other client's public keys.
4791 * Renamed verify_server_key client operation to verify_public_key
4792 and added one argument to indicate the type of the connection
4793 (server, client etc.).
4795 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added silc_server_connection_auth_request to handle the
4798 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4799 silcd/packet_receive.[ch].
4801 * Added silc_server_send_connection_auth_request into the
4802 silcd/packet_send.c to send the connection auth request packet.
4804 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4807 * Fixed the public key authentication in responder side in the
4808 server. The `auth_data' pointer includes the SilcPublicKey
4809 not the path to the public key. Affected file silcd/protocol.c.
4811 * Implemented the public key authentication in the initiator side
4812 in the server. Affected file silcd/protocol.c.
4814 * Removed the [RedirectClient] config section from the server
4815 configuration. Is not needed and I don't want to implement it.
4817 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Cleaned up the CMODE command in the server. It now works
4820 correctly and supports all the modes defined in the protocol.
4821 Affected file is silcd/command.c.
4823 * Added `hmac_name' field to the SilcChannelEntry in the server
4824 to hold the default HMAC of the channel. It can be set when
4825 creating the channel (with JOIN command). Affected files
4828 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4829 type to indicate the change of the current cipher and hmac
4830 on the channel. Client can safely ignore the <cipher> argument
4831 (if it chooses to do so) since the CHANNEL_KEY packet will
4832 force the channel key change anyway. The <hmac> argument is
4833 important since the client is responsible of setting the new
4834 HMAC and the hmac key into use.
4836 * Fixed the CMODE command in the client library as well.
4838 * Tested CMODE command in router environment successfully.
4840 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Show the version of the remote client (or server) when connecting
4843 to the server. It is logged to the log file. Affected file
4844 is silcd/protocol.c.
4846 * Fixed the KILLED notify handling in the client library. The
4847 client must be removed from all channels when receiving the
4850 Also, do not remove the client entry when giving the KILL
4851 command but when the KILLED notify is received.
4853 * Removed silc_idlist_find_client_by_nickname from the server.
4854 Not needed anymore. Affected files silcd/idlist.[ch].
4856 * Implemented the CHANNEL_CHANGE notify type handling to the
4857 server. Affected file silcd/server.c.
4861 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added silc_server_send_notify_invite to send the INVITE
4864 notify between routers.
4866 * Implemented the INVITE command correctly to the server.
4868 * Implemented the INVITE notify type handling in the server.
4870 * Implemented the INVITE command to the client library and on the
4873 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added function silc_server_get_client_resolve to find the
4876 client entry by ID from all ID lists and then resolve it
4877 (using WHOIS) if it cannot be found. Affected file is
4880 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Implemented the BAN command to the client library.
4884 * The JOIN command in the server now checks the invite list
4887 * Changed the silc_command_reply_payload_encode_va and the
4888 silc_command_payload_encode_va to support that if argument is
4889 NULL it ignores and checks the next argument. Affected file
4890 lib/silccore/silccommand.c.
4892 * Added silc_server_send_notify_ban to send the BAN notify
4893 type between routers.
4895 * Chaned the silc_notify_payload_encode to support that if
4896 argument is NULL it ignores and checks the next argument.
4897 Affected file lib/silccore/silcnotify.c.
4899 * Tested ban lists in router environment successfully.
4901 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Implemented BAN command to the server, in silcd/command.[ch].
4905 * Removed the BAN and INVITE_LIST modes from the CMODE command
4908 * Added function silc_string_match to regex match two strings.
4909 Affected files lib/silcutil/silcutil.[ch].
4911 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Redefined parts of the SilcChannelEntry in the server to support
4914 the new ban and invite lists.
4916 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Redefined the INVITE command. The same command can be used to
4919 invite individuals to the channel but also to manage the invite
4920 list of the channel (to add to and remove from the invite list).
4921 Updated the protocol specs.
4923 * Added new command SILC_COMMAND_BAN that can be used to manage
4924 the ban list of the channel. Updated the protocol specs.
4926 * Removed the channel modes: the SILC_CMODE_BAN and the
4927 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4928 in the CMODE command. The equivalent features are now available
4929 using INVITE and BAN commands. Updated the protocol specs.
4931 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4932 in the network about change in the current ban list. The notify
4933 type is not used by the client.
4935 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4936 support the invite lists.
4938 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4940 * Added new function silc_string_regexify that converts string
4941 including wildcard characters into regex string that can
4942 be used by the GNU regex library. Added into the file
4943 lib/silcutil/silcutil.[ch].
4945 Added silc_string_regex_combine to combine to regex strings
4946 into one so that they can be used as one regex string by
4947 the GNU regex library. Added into the file
4948 lib/silcutil/silcutil.[ch].
4950 Added silc_string_regex_match to match two strings. It returns
4951 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4953 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Imported GNU regex to the soruce tree into lib/contrib.
4956 Fixed some compiler warning from the regex.c.
4958 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Fixed MOTD command in the server to work in router environment.
4962 * Fixed the MOTD command in the client library to support
4963 the server argument in the command.
4965 * Added `nickname_len' argument to the silc_idlist_add_client
4966 in the server, as the `nickname' argument may be binary data
4969 * Added silc_idlist_get_channels to return all channels from
4972 * Implemented LIST command to the server. Affected file is
4975 * Implemented the LIST command to the client library and on the
4978 * Added [<user count>] argument to the LIST command reply.
4979 With private channels the user count is not shown.
4981 * Updated TODO and README.
4983 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * The client entry's data.registered must be TRUE even with
4986 global client entry on global client list. The data.registered
4987 is used to check whether the client is anymore in the network,
4988 for example with WHOWAS command so it must be valid.
4990 * Fixed the WHOWAS command in the server. It now actually works
4991 in router environment. Added function into silcd/command_reply.c
4992 silc_server_command_reply_whowas_save.
4994 * Added silc_idlist_purge function to the silcd/idlist.c
4995 to periodically purge the ID Cache.
4997 * Fixed INFO command in the server. It works now in router
4998 environment. Added <server name> argument to the INFO command
4999 reply. Updated the protocol specs.
5001 * Fixed minor bug in silc_idcache_purge to not purge if the
5002 expire value is zero.
5004 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5005 they were buggy because of the WHOWAS information.
5007 * Fixed local command MSG to handle the async resolving of
5008 the remote client properly. It used to fail the first MSG.
5009 Affected file silc/local_command.c.
5011 * Added `data_len' field to SilcIDCache context.
5013 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Update TODO. Todo in commands in the server.
5017 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5020 used by routers as broadcast packet to inform other routers
5021 about the changed user mode.
5023 Implemented the notify handling in the server. Affected file is
5024 silcd/packet_receive.c. Added the function
5025 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5027 * Added new generic Channel Payload and deprecated the New Channel
5028 Payload. The New Channel Payload is now the generic Channel
5031 * Added new argument `mode' to the silc_server_send_new_channel
5032 as it is required in the Channel Payload now.
5034 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5035 and created a new and real SilChannelPayload to represent the
5036 new generic Channel Payload. Implemented the encode/decode
5037 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5039 * Added silc_server_get_client_channel_list to return the list
5040 of channels the client has joined for WHOIS command reply.
5041 Affected file silcd/server.[ch].
5043 * Implemented the channel list sending in the WHOIS command reply
5044 in server and in the client.
5046 Implemented the channel list displaying on the user interface
5047 as well. Affected file silc/client_ops.c.
5049 * Added silc_channel_payload_parse_list to parse list of Channel
5050 Payloads. It returns SilcDList list of SilcChannelPayloads.
5051 Client for example can use this function to parse the list of
5052 channels it receives in the WHOIS command reply. The caller
5053 must free the list by calling silc_channel_payload_list_free.
5054 Affected files lib/silccore/silcchannel.[ch].
5056 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added one new argument <user mode> to the WHOIS command reply
5059 to return the mode of the user in SILC. Updated the protocol
5062 Implemented it to the server and client.
5064 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Fixed the mode printing on the user interface on joining.
5067 Affected file silc/client_ops.c.
5069 * Implemented the UMODE command and user modes in general to the
5070 client library and to the user interface.
5072 * Implemented the UMODE command to the server.
5074 * The server now sends UNKNOWN_COMMAND error status if client sends
5075 unknown command. Affected file silcd/command.c.
5077 * All server commands now handle the command identifier the right
5078 way when sending the command reply to the client. The client can
5079 use to identify the command replies with the identifier.
5081 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Added silc_server_get_client_route to resolve the route to
5084 the client indicated by the client ID. Affected file is
5087 * Added silc_server_relay_packet as general function to relay
5088 packet to arbitrary destination. This deprecates functions
5089 like _send_private_message_key, _relay_notify etc. Affected
5090 file is silcd/packet_send.[ch].
5092 Removed silc_server_send_key_agreement,
5093 silc_server_send_private_message_key and
5094 silc_server_packet_relay_notify functions from the file
5095 silcd/packet_send.[ch].
5099 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5100 server. Affected file silcd/packet_receive.[ch].
5102 * Implemented the KILL command to the client. Implemented the
5103 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5104 Affected files lib/silcclient/command[_reply].c and
5105 lib/silcclient/client_notify.c. Implemented the KILL notify
5106 printing in the user inteface.
5108 * Fixed a lot silc_parse_nick memory leaks from the client
5109 library in the file lib/silcclient/command.c.
5111 * Changed the silc_server_send_notify_on_channels's `sender'
5112 argument from SilcSocketConnection to SilcClientEntry to
5113 check the sender as entry and not as connection object and not
5114 to send to the client provided as argument. The affected file
5115 is silcd/packet_send.[ch].
5117 * The notify packets that are destined directly to the client used
5118 to not to be processed by the server. Now changed that and the
5119 server processes all notify packets. After relaying the packet
5120 to the client the notify packet is processed in the server.
5122 * The silc_server_free_client_data now checks whether there is
5123 pending outgoing traffic for the client and purges the data to
5124 the network before removing the client entry.
5126 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5129 an client is killed from the SILC Network. Updated the protocol
5132 Added new function silc_server_send_notify_killed to the
5133 silcd/packet_send.[ch].
5135 * Added function silc_server_packet_relay_notify to relay notify
5136 packets that are destined directly to a client. In this case
5137 the server does not process the notify packets but merely relays
5138 it to the client. Affected file silcd/packet_send.[ch].
5140 Added also silc_server_packet_process_relay_notify to check
5141 whereto relay the notify. Affected file is
5142 silcd/packet_receive.[ch].
5144 * Implemented the KILL command to the server.
5148 * Added the backup schema desgined last fall to the protocol
5149 specs for everyone to see. The specification is in the
5150 *-spec-xx.txt draft and the packet type definitions for the
5151 backup routers is in *-pp-xx.txt draft. Thusly, added also
5152 new packet type SILC_PACKET_CELL_ROUTERS.
5154 * A big security problem in the implementation discovered. The
5155 signoff of an client did not cause new channel key generation
5156 which it of course should've done. The channel keys must be
5157 always re-generated when client leaves (or signoffs) the channel.
5158 The silc_server_remove_from_channels funtion now handles
5159 the channel key re-generation.
5161 * Added `sender' argument to the silc_server_send_notify_on_channels
5162 to not to send the client provided as argument. Affected file
5163 silcd/packet_send.[ch].
5165 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Implemented OPER and SILCOPER commands into the server and
5170 * Added silc_auth_verify and silc_auth_verify_data to verify
5171 the authentication directly from the authentication payload.
5172 It supports verifying both passphrase and public key based
5173 authentication. Affected file lib/silccore/silcauth.[ch].
5175 * Added `hash' field to the SilcIDListData structure. It is the
5176 hash negotiated in the SKE protocol. Affected file is
5179 * Slight redesigning of the SilcAuthPayload handling routines.
5180 Do not send SilcPKCS but SilcPublicKey as argument.
5182 * Implemented the public key authentication support to the
5183 serverconfig. The public key is loaded from the provided path
5184 and saved as authentication data to void * pointer. Thus,
5185 changed the unsigned char *auth_data to void *auth_data;
5187 * Fixed SHUTDOWN command to send the reply before the server
5188 is shutdown. :) Affected file silcd/command.c.
5190 * Fixed fatal bug in CONNECT command. The hostname was invalid
5191 memory and server crashed. Affected file silcd/command.c.
5193 * Fixed fatal bug in CLOSE command. The server_entry became
5194 invalid but was referenced later in the command. Affected file
5197 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Fixed fatal bug in failure packet handling. Server ignored
5200 the failure and thus crashed when it came.
5204 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5207 that the command may be executed only once in (about) 2 seconds.
5208 The old SILC_CF_LAG flag is same but allows command bursts up
5209 to five before limiting.
5211 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5212 server code. Various commands now includes the CF_LAG_STRICT
5213 flag to disallow any kind of miss-use of the command.
5215 * Fixed the silc_buffer_unformat to not to allocate any data
5216 if the length of the data is zero. It used to allocate the
5217 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5219 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Changed the format of AdminConnection configuration section
5222 in the server. Added username of the admin to the format.
5223 Affected files silcd/serverconfig.[ch].
5225 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5226 to return admin configuration data by host, username and/or
5229 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * Implemented WHOWAS command to the server. Added the functions:
5233 silc_server_command_whowas_parse,
5234 silc_server_command_whowas_send_reply,
5235 silc_server_command_whowas_from_client and
5236 silc_server_command_whowas_from_server
5238 * Added <Client ID> argument to the WHOWAS command reply. Updated
5239 the protocol specs accordingly.
5241 * Implemented WHOWAS command and command_reply to the client
5244 Implemented the WHOWAS printing on the user interface.
5246 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Added new argument to the WHOWAS command reply, the real name.
5249 It is an optional argument. Updated the protocol specs.
5251 * Added SilcIDCacheDestructor callback that is registered when
5252 the SilcIDCache is allocated. The callback is called when
5253 an cache entry in the ID Cache expires, or is purged from the
5254 cache. Added into lib/silccore/idcache.[ch].
5256 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5257 to destruct the client entries when the cache entry expires.
5258 Other ID Cache's in server and in the client library ignores
5261 * If the ID Cache entry's `expire' field is zero then the entry
5262 never expires. Added boolean `expire' argument to the
5263 silc_idcache_add function in the lib/silccore/idcache.[ch].
5264 If it is TRUE the default expiry value is used.
5266 * Added silc_server_free_client_data_timeout that is registered
5267 when client disconnects. By default for 5 minutes we preserve
5268 the client entry for history - for WHOWAS command.
5270 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * Added support to the server to enforce that commands are not
5273 executed more than once in 2 seconds. If server receives
5274 commands from client more frequently, timeout is registered
5275 to process the commands. Affected file silcd/command.c.
5276 Added new function silc_server_command_process_timeout.
5278 * Changed NICK_NOTIFY handling in client library to check that
5279 if the client's nickname was changed, so there is no need to
5280 resolve anything from the server.
5282 * Removed error printing from the WHOIS and IDENTIFY commands.
5283 If error occurs then it is ignored silently in the client library.
5284 The application, however, may map the received error to
5285 human readable error string. The application currently maps
5286 the NO_SUCH_NICKNAME error to string.
5288 * Made the command status message public to the application. Moved
5289 them from lib/silcclient/command_reply.c to
5290 lib/silcclient/command_reply.h. The application can map the
5291 received command status to the string with the
5292 silc_client_command_status_message function.
5294 * Added check to the server to check that client's ID is same
5295 as the Source ID in the packet the client sent. They must
5298 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Added dist-bzip hook to the Makefile.am to make bzip2
5301 compressed distributions.
5303 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Server now enforces the maximum length for the nickname and
5306 the channel as protocol specification dictates. 128 bytes for
5307 nickname and 256 bytes for channel name.
5309 * Moved the WHOIS printing to the application. The client libary
5310 does not print out the WHOIS information anymore, the application
5311 must do it. Renamed silc_client_command_reply_whois_print to
5312 the silc_client_command_reply_whois_save.
5314 The client's idle time is also sent to the application now, and
5315 the idle is shown on screen.
5317 * Added silc_client_command_reply_identify_save to save the
5318 received IDENTIFY entries.
5320 * Do not check for channel private keys in message sending and
5321 reception if the channel does not have the PRIVKEY mode set.
5322 Affected file lib/silclient/client_channel.c.
5324 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5327 just surfaced after chaning the JOIN procedure.
5329 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Added silc_client_get_clients_by_list to get client entries
5332 from Client ID list, that is returned for example by JOIN
5333 and USERS command replies. The application should use this
5334 function for example when JOIN command reply is received to
5335 resolve the clients already on the channel (library does not
5336 do that anymore as USERS command reply is not used in the JOIN
5337 procedure anymore). Affected files lib/silcclient/silcapi.h and
5338 lib/silcclient/idlist.c.
5340 * JOIN command reply and USERS command reply returns now SilcBuffer
5341 pointers instead of unsigned char pointers when returning
5342 the client list and mode list.
5344 * Added <Client ID> argument to the JOIN command reply, mainly
5345 for the server to identify for which client the command was
5346 originally sent. Updated protocol specs accordingly.
5348 * Added SilcDlist private_key pointer to the SilcChannelEntry
5349 in the client to support the channel private keys. Affected
5350 file is lib/silcclient/idlist.h.
5352 * Added SilcChannelPrivateKey argument to the function
5353 silc_client_send_channel_message so that application can choose
5354 to use specific private ke if it wants to. If it is not provided,
5355 the normal channel key is used, unless private keys are set.
5356 In this case the first (key that was added first) is used
5357 as the encryption key.
5359 * Implemented the support for channel private key handling.
5360 Implemented the following functions:
5362 silc_client_add_channel_private_key,
5363 silc_client_del_channel_private_keys,
5364 silc_client_del_channel_private_key,
5365 silc_client_list_channel_private_keys and
5366 silc_client_free_channel_private_keys
5368 Affected file lib/silcclient/client_channel.c.
5370 * Added the support for the private keys in the channel message
5371 sending and encryption and in the message reception and
5372 decryption. Affected funtions are
5373 silc_client_send_channel_message and silc_client_channel_message.
5375 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Added SKE's key verify callback to the client library's
5378 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5380 * Removed the statement that server (or router) must send USERS
5381 command reply when joining to the channel so that the client
5382 knows who are on the channel. Instead, the client list and
5383 client's mode list is now sent in the JOIN command reply to the
5384 client who joined channel. This is better solution.
5386 * Added function silc_server_get_users_on_channel and function
5387 silc_server_save_users_on_channel to the silcd/server.[ch].
5389 * Removed function silc_server_command_send_users from the
5392 * Do not show topic on the client library anymore. The topic is
5393 sent in the command reply notify to the application and the
5394 application must show the topic now.
5396 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Added client searching by nickname hash into the IDENTIFY and
5399 WHOIS commands in the server as they were clearly missing from
5400 them. Affected file is silcd/command.c.
5402 * Fixed a bug in private message receiving in the client library.
5403 The remote ID was freed and it wasn't supposed, now it is
5406 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Minor fix to the channel payload; allocate the data area, as it
5409 needs to be of specific length.
5411 * If the key agreement port is zero then the operating
5412 system will define the bound port. Affected files are
5413 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5415 * Added new function silc_channel_payload_decrypt into the file
5416 lib/silccore/silcchannel.[ch].
5418 * Moved the channel message etc, check from silc_packet_decrypt
5419 to applications. The library calls now a generic
5420 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5421 when the packet is either normal or special. This was done to
5422 allow more wide range of checking that was not allowed when
5423 the code was in library. Now applications can do virtually any
5424 checks to the packet and return to the library the decision how
5425 the packet should be processed. Affected files are
5426 lib/silccore/silcpacket.[ch].
5428 Added silc_server_packet_decrypt_check to the server and
5429 silc_client_packet_decrypt_check to the client library.
5431 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5432 to send with specified source and destination information.
5434 * Channel message delivery between routers was broken after the
5435 channel key distribution was fixed earlier. The channel key
5436 was used be to distributed to other routers as well which is not
5437 allowed by the protocol. Now this is fixed and channel keys
5438 really are cell specific and the channel message delivery between
5439 routers comply with the protocol specification.
5441 * Fixed various commands in server to check also the global list
5442 for the channel entry and not just the local list. The affected
5443 file silcd/command.c.
5445 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added assert()s to buffer formatting and unformatting routines
5448 to assert (if --enable-debug) when error occurs. Affected
5449 file: lib/silcutil/silcbuffmt.c.
5451 * Changed to auto-reconnect to check whether the remote host is
5452 router and register the re-connect timeout if it is. It used
5453 to check that whether we are normal server, but router must do
5454 auto-reconnect with another router as well. Affected file
5457 * Removed the [<key len>] option from CMODE command as the cipher
5458 name decides the key length, nowadays. See the defined ciphers
5459 from the protocol specification.
5461 * Added [<hmac>] option to the CMODE command to define the HMAC
5462 for the channel. Added SILC_CMODE_HMAC channel mode.
5464 * Added [<hmac>] option for the JOIN command so that user can
5465 select which HMAC is used to compute the MACs of the channel
5468 * Added Hmac field to the Channel Message Payload. The integrity
5469 of plaintext channel messages are now protected by computing
5470 MAC of the message and attaching the MAC to the payload. The
5471 MAC is encrypted. Now, it is clear that this causes some
5472 overhead to the size of the packet but rationale for this is that
5473 now the receiver can verify whether the channel message decrypted
5474 correctly and also when private keys are set for the channel the
5475 receiver can decrypt the packet with several keys and check from
5476 the MAC which key decrypted the message correctly.
5478 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5479 lib/silccrypt/silccipher.[ch].
5481 * Added silc_hash_len to return the digest length into the
5482 lib/silcrypt/silchash.[ch].
5484 * Rewrote parts of Silc Channel Payload interface in the
5485 lib/silccore/silcchannel.[ch]. The encode function now also
5486 encrypts the packet and parse function decrypts it.
5488 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Fixed a minor formatting bug in the SKE's key material processing.
5491 It actually might have processed the keys wrong way resulting
5494 * Redefined the mandatory HMAC algorithms and added new algorithms.
5495 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5496 and hmac-md5 truncated to 96 bits. The mandatory is now
5497 hmac-sha1-96. Rest are optional (including the one that used
5498 to be mandatory). Rationale for this is that the truncated HMAC
5499 length is sufficient from security point of view and can actually
5500 make the attack against the HMAC harder. Also, the truncated
5501 HMAC causes less overhead to the packets. See the RFC2104 for
5504 * Added new [hmac] configuration section. The SKE used to use
5505 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5506 is of course wrong. The official names that must be proposed in
5507 the SKE are the ones defined in the protocol specification
5508 (hmac-sha1-96 for example). The user can configure any hmac
5509 using any hash function configured in the [hash] section. At
5510 least, the mandatory must be configured.
5512 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5514 * Added HMAC list to the SKE proposal list. It has now both
5515 hash algorithm list and HMAC list. This makes the protocol
5516 incompatible with previous versions. The SKE now seems to work
5517 the way it is supposed to work, for the first time actually.
5519 * Defined plain Hash algorithms to the protocol specification.
5522 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Implemented support for key agreement packets into the server.
5525 Added functions silc_server_key_agreement and
5526 silc_server_send_key_agreement. Other than these functions,
5527 server has nothing to do with this packet.
5529 * Added support for private message key packets into the server.
5530 Added functions silc_server_private_message_key and
5531 silc_server_send_private_message_key.
5535 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5536 called in the protocol's final callback instead in the END
5537 protocol state. This makes a little more sense and in the same
5538 time in client we can use the same protocol routines for normal
5539 key exchange and to key agreement packet handling as well.
5541 * Added to both client's and server's KE protocol context the
5542 SilcSKEKeyMaterial pointer to save the key material. We will
5543 bring the key material to the protocol's final callback by doing
5544 this. The final callback must free the key material.
5546 * Added SKE's packet_send callback into client's KE protocol
5547 context so that the caller can choose what packet sending function
5548 is used. This way we can use different packet sending when
5549 doing normal SKE when doing key agreement packet handling (in
5550 the key agreement packet handling we do not want to encrypt
5553 * Implemented the responder side of the key agreement routines
5554 in the client. The client can now bind to specified port and
5555 accept incoming key negotiation. The key material is passed
5556 to the application after the protocol is over.
5558 * Implemented the processing of incoming Key Agreement packet
5559 in the client. Added function silc_client_key_agreement to
5562 * Implemented the intiator side of the key agreement routines
5563 in the client. The client can now initiate key agreement with
5564 another remote client. The key material is passed to the
5565 application after the protocol is over.
5567 * Created client_keyagr.c to include all the key agreement
5570 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5571 SILC_TASK_CALLBACK except that it is not static.
5573 * Created client_notify.c and moved the Notify packet handling
5574 from the client.[ch] into that file.
5576 * Created client_prvmsg.c and moved all private message and
5577 private message key routines from the client.[ch] into that file.
5579 * Create client_channel.c and moved all channel message and
5580 channel private key routines from the client.[ch] into that file.
5582 * Changed silc_client_get_client_by_id_resolve to resolve with
5583 WHOIS command instead of IDENTIFY command, in the file
5584 lib/silclient/idlist.c.
5586 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Implemented the SKE's responder side to the Client library.
5590 * When FAILURE is received to the protocol do not trust it
5591 blindly. Register a timeout to wait whether the remote closes
5592 the connection as it should do it, only after that process the
5593 actual failure. This was changed to both client and server.
5595 * Added client_internal.h to include some of the structures
5596 there instead of client.h in lib/silcclient/.
5598 * Added function silc_task_unregister_by_callback to unregister
5599 timeouts by the callback function.
5601 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Some "Incomplete WHOIS info" errors has been appearing on the
5604 log files. Took away the entry->userinfo check from WHOIS
5605 reply sending. The entry->userinfo is now " " if client did not
5606 provide one. I thought this was fixed earlier but something
5607 is wrong still. Let's see if the error still appears.
5609 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Fixed a minor bug in the login when the channel key is
5612 re-generated in the server. It used to generate the key in
5613 wrong order and thus caused problems in the channel traffic.
5615 * Fixed a minor bug in channel key distsribution after
5616 KICK command. The key was not sent to the router even though
5619 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Added silc_ske_process_key_material_data as generic routine
5622 to process any key material as the SILC protocol dictates. The
5623 function is used by the actual SKE library but can be used by
5624 applications as well. This relates to the private message keys
5625 and the channel private keys since they must be processed the
5626 same way the normal SILC session keys. The protocol dictates
5627 this. Affected files: lib/silcske/silcske.[ch].
5629 Added also silc_ske_free_key_material to free the
5630 SilcSKEKeyMaterial structure.
5632 * Defined silc_cipher_set_key function to set the key for
5633 cipher without using the object's method function. The affected
5634 files: lib/silccrypt/silccipher.[ch].
5636 * Implemented silc silc_client_add_private_message_key,
5637 silc_client_add_private_message_key_ske,
5638 silc_client_del_private_message_key,
5639 silc_client_list_private_message_keys and
5640 silc_client_free_private_message_keys functions in the
5643 Added functions silc_client_send_private_message_key to send
5644 the Private Message Key payload and silc_client_private_message_key
5645 to handle incoming Private Message Key payload.
5647 * Added Cipher field to the Private Message Key payload to set
5648 the cipher to be used. If ignored, the default cipher defined
5649 in the SILC protocol (aes-256-cbc) is used.
5651 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Removed lib/silcclient/ops.h file.
5655 Redefined parts of the SILC Client Library API. Created new
5656 file silcapi.h that deprecates the ops.h file and defines the
5657 published Client Library API. Defined also private message key
5658 API and channel private key API into the file.
5660 This is the file that the application must include from the
5661 SILC Client Library. Other files need not be included by
5662 the application anymore.
5664 * Added new key_agreement client operation callback and also
5665 defined the Key Agreement library API for the application.
5667 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5670 is used by clients to request key negotiation between another
5671 client in the SILC network. If the negotiation is started it
5672 is performed using the SKE protocol. The result of the
5673 negotiation, the secret key material, can be used for example
5674 as private message key.
5676 Implemented the Key Agreement payload into the files
5677 lib/silccore/silauth.[ch].
5679 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Redefined ciphers for the SILC protocol. Added some new ciphers
5682 and defined the key lengths for the algorithms. Changed the
5683 code accordingly. The default key length is now 256 bits.
5685 * Fixed SKE key distribution function silc_ske_process_key_material
5686 when the key length is more than 128 bits. The default key
5687 length in SILC is now 256 bits.
5689 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5690 to indicate unsupported algorithm.
5692 * Renamed rijndael.c to aes.c and all functions as well.
5694 * Fixed a long standing channel key setting bug in client library.
5695 Weird that it has never surfaced before.
5697 * Fixed bug in channel deletion. If the entire channel is removed
5698 then it must also delete the references of the channel entry
5699 from the client's channel list as the client's channel entry and
5700 the channel's client entry share same memory.
5702 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Implemented CONNECT and SHUTDOWN commands in the client.
5706 * Implemented CLOSE command to the client.
5708 * Added the function silc_idlist_find_server_by_name into the
5709 files silcd/idlist.[ch].
5711 Added the function silc_idlist_find_server_by_conn into the
5712 files silcd/idlist.[ch].
5714 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * DIE command was renamed to SHUTDOWN. Updated the both code
5719 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5720 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5722 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5725 * Added function silc_server_create_connection function to create
5726 connection to remote router. My server implementation actually
5727 does not allow router to connect to normal server (it expects
5728 that normal server always initiates the connection to the router)
5729 so the CONNECT command is only good for connecting to another
5732 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5735 or some other client was kicked from the channel.
5737 Implemented the handling of the notify type to both client
5740 Implemented silc_server_send_notify_kicked to send the KICKED
5741 notify. It is used to send it to the server's primary router.
5743 * Implemented the KICK command into server and client.
5745 * Added `query' argument to the silc_idlist_get_client function
5746 to indicate whether to query the client from server or not if
5749 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5750 to indicate that the client is not channel founder.
5754 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Removed the rng context from SilcPacketContext structure and
5757 changed that the packet routine uses the Global RNG API.
5759 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added support for quit message that client can "leave" on the
5762 channel when it quits the SILC. It is ditributed inside the
5763 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5765 Added silc_server_free_client_data that will take the
5766 signoff message as argument.
5768 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5770 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Updated parts of the protocol specification to keep it up
5775 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5778 payloads in one packet.
5780 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5781 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5782 use now the new List flag.
5784 * Also deprecated the following packet types: REPLACE_ID,
5785 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5787 * Added list support for Notify packet in server.
5789 * Added silc_server_send_notify_channel_change to send the
5790 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5791 the silc_server_send_replace_id.
5793 * Added silc_server_send_notify_nick_change to send the
5794 NICK_CHANGE notify type. Deprecates the function
5795 silc_server_send_replace_id.
5797 * Added silc_server_send_notify_join to send the JOIN notify type.
5798 Deprecates the function silc_server_send_new_channel_user.
5800 * Added silc_server_send_notify_leave to send LEAVE notify type.
5801 Deprecates the function silc_server_send_remove_channel_user.
5803 * Added silc_server_send_notify_cmode and
5804 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5805 types. Deprecates the silc_server_send_set_mode function.
5807 * Added SERVER_SIGNOFF notify type to indicate that server has
5808 quit. This means that all clients on the channel from that
5809 server will drop. This can be also used when netsplit happens.
5811 Deprecated REMOVE_ID packet type since it is not needed anymore
5814 Added silc_server_send_notify_server_signoff to send the
5815 SERVER_SIGNOFF notify type. Deprecates the function
5816 silc_server_send_remove_id.
5818 Added also silc_server_send_notify_signoff to send the
5819 SIGNOFF notify type.
5821 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5822 SILC protocol from this day on. Changed the protocol
5823 specification as well.
5825 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5826 notify type. It is used between routers to notify about
5827 topic changes on a channel.
5829 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5832 * Partly updated the protocol specification to comply with the
5833 changes now made. It is still though a bit outdated.
5835 * The JOIN notify type now takes one extra argument <Channel ID>.
5836 The packet used to be destined to the channel but now the
5837 JOIN type may be sent as list thus it is impossible to
5838 destine it to any specific channel. By adding this argument
5839 it is again possible.
5841 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Added CREDITS file. The CHANGES and CREDITS file will appear
5844 in the distribution as well.
5846 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5849 types in the server's silcd/packet_receive.c.
5851 * Implemented CMODE and CUMODE to work in router environment.
5853 * Fixed minor encoding and decoding buglet from the
5854 lib/silccore/silcmode.c.
5856 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5859 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5861 * Changed all SilcConfigServer* and silc_config_server* to
5862 SilcServerConfig* and silc_server_config*, respectively.
5865 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Associated the ID (client or server ID) to the Authentication
5868 Payload to avoid any possibility of forging. Updated the
5869 protocol specification and the code accordingly.
5871 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * The RSA key length is now save to the RsaKey context in the
5874 key generation process in lib/silccrypt/rsa.c. The key length
5875 is now used to figure out the maximum size of the block allowed
5876 to be encrypted/signed.
5878 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5879 is equivalent to the silc_mp_mp2bin but does not allocate any
5882 * Changed silc_mp_mp2bin API to take length argument. If it is
5883 non-zero then the buffer is allocated that large. If zero, then
5884 the size is approximated using silc_mp_sizeinbase, which however
5887 * Created Global RNG API which is global RNG that application can
5888 initialize. After initializing, any routine anywhere in the
5889 code (including library) can use RNG without allocating a new
5890 RNG object. This was done to allow this sort of use of the
5891 RNG in code that has no chance to allocate RNG object. All
5892 applications currently allocate this and many routines in the
5893 library use this. Affected file lib/silccrypt/silcrng.[ch].
5895 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5896 it to use the Global RNG API.
5898 * Defined Authentication Payload into protocol specification that
5899 is used during SILC session to authenticate entities. It is
5900 used for example by client to authenticate itself to the server
5901 to obtain server operator privileges.
5903 Implemented this payload into the lib/silccore/silcauth.[ch].
5904 Implemented also routines for public key based authentication
5905 as the new protocol specification dictates.
5907 Moved definitions of different authentication methods from
5908 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5910 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5911 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5912 silc_pkcs_verify_with_hash functions into the file
5913 lib/silccrypt/silcpkcs.[ch].
5915 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * The client entry's userinfo pointer must be always valid.
5918 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5919 will fail since it requires the userinfo. Now, the userinfo
5920 is allocated as "" if actual userinfo does not exist. Actually,
5921 it must exist and it is totally Ok to drop client connections
5922 that does not announce the userinfo. However, we will make
5923 this workaround for now.
5925 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5926 to return the remote port by socket.
5928 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5931 SILC_SERVER_PENDING_EXEC and added an new macro
5932 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5933 data or when error occurs while processing the pending command.
5935 Added new argument `destructor' into silc_server_command_pending
5936 and to the SilcServerCommandPending object. This destructor is
5937 now called after calling the pending callback or if error occurs
5938 immediately. If error occurs the actual pending callback won't
5939 be called at all - only the destructor. The destructor may be
5940 NULL if destructor is not needed.
5942 All this applies for client library code as well. Similar
5943 changes were made there as well for the pending commands.
5945 In the client, the application must now allocate the
5946 SilcClientCommandContext with the silc_client_command_alloc
5949 * Added reference counter to the SilcServerCommandContext. Added
5950 function silc_server_command_alloc and silc_server_command_dup
5953 Same type of functions added to the client library for the same
5956 * Removed the cmd_ident from IDListData away since it is now
5957 global for all connections. It is the command identifier used
5958 in command sending and with pending commands. The affected file
5961 * Added reference counter to the SilcSocketConnection objecet to
5962 indicate the usage count of the object. The object won't be
5963 freed untill the reference counter hits zero. Currently only
5964 server uses this, and client ignores it. The client must be
5965 set to use this too later. The affected files are
5966 lib/silccore/silcsockconn.[ch]. Added also the function
5967 silc_socket_dup to increase the reference counter.
5969 This was mainly added because it is possible that the socket
5970 is removed underneath of pending command or other async
5971 operation. Now it won't be free'd and proper DISCONNECTING
5972 flags, etc. can be set to avoid sending data to connection that
5973 is not valid anymore.
5975 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5976 the connection. After that it sets SILC_SET_DISCONNECTED.
5977 It is, however, possible that the socket data is not still freed.
5978 The silc_server_packet_process now checks that data is not
5979 read or written to connection that is DISCONNECTED. The socket
5980 get's freed when the reference counter hits zero.
5982 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Changed the client operation API: channel_message operation's
5985 `sender' is now the client entry of the sender, not the nickname
5986 and the `channel' is the channel entry, not the channel name.
5988 In the private_message operation the `sender' is now also the
5989 client entry of the sender not the nickname.
5991 Affected file is lib/silcclient/ops.h and all applications
5992 using the client operations.
5994 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Moved the calling of ops->connect() from connect_to_server_final
5997 into receive_new_id functin since that is the point when the
5998 client is actually allowed to send traffic to network. The
5999 affected file is lib/silcclient/client.c.
6001 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6004 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6005 (if needs broadcasting) instead of broadcasting the packets one
6006 by one which would make a burst in the network traffic.
6008 * Added `broadcast' argument to the functions in silcd/server.[ch]
6009 silc_server_create_new_channel[_with_id] to indicate whether
6010 to send New Channel packet to primary router.
6012 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Added new function into the silcd/server.[ch] files:
6015 silc_server_create_new_channel_with_id to create new channel with
6016 already existing Channel ID.
6018 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6019 lib/silccore/silcpacket.h. This packet is used t send list of
6020 Set Mode payloads inside one packet. Server uses this to set
6021 the modes for the channels and clients on those channels, that it
6022 announced to the router when it connected to it. The protocol
6023 specification has been updated accordingly.
6025 * The silc_server_new_channel did not handle the packet coming
6026 from normal server as it normally does not send that. However,
6027 when it announces its channels it does send it. Implemented
6028 the support for that.
6030 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6031 into the file lib/silccore/id.h.
6033 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Fixed memory leaks in the functions silc_idlist_del_client,
6036 silc_idlist_del_channel and silc_idlist_del_server in the file
6037 silcd/idlist.c. All of those leaked like a sieve.
6039 * Fixed some small memory leaks in the client's function
6040 silc_client_notify_by_server.
6042 * Added functions into silcd/server.c: silc_server_announce_clients,
6043 silc_server_announce_channels and silc_server_announce_server.
6044 These functions are used by normal and router server to announce
6045 to its primary router about clients, channels and servers (when
6046 router) that we own. This is done after we've connected to the
6049 These functions effectively implements the following packet types:
6050 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6051 and SILC_PACKET_NEW_ID_LIST.
6053 * Added new functions into the silcd/packet_receive.[ch]:
6054 silc_server_new_id_list, silc_server_new_channel_list and
6055 silc_server_new_channel_user_list to handle the incoming
6056 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6058 * Added support of changing Channel ID in the function
6059 silc_server_replace_id. If the server that announces a channel
6060 to the router already exists in the router (with same name but
6061 with different Channel ID), router is responsible to send
6062 Replace ID packet to the server and force the server to change
6063 the Channel ID to the one router has.
6065 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6066 client that the Channel ID has been changed by the router. The
6067 normal server sends this to the client. Client must start using
6068 the new Channel ID as the channel's ID.
6070 Implemented handling of this new type into lib/silcclient/client.c
6071 into the function silc_client_notify_by_server.
6073 * Added new function silc_idlist_replace_channel_id into the files
6074 silcd/idlist.[ch] to replace the Channel ID.
6076 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * Call silc_server_command_identify_check always when processing
6079 the IDENTIFY command in silcd/command.c
6081 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6084 send keepalive packets. The packet can be sent by clients,
6085 servers and routers.
6087 Added function silc_socket_set_heartbeat into the file
6088 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6089 If not set, the heartbeat is not performed. The actual
6090 heartbeat is implemented in the low level socket connection
6091 library. However, application is responsible of actually
6094 Added silc_server_send_heartbeat to send the actual heartbeat
6095 packet into silcd/packet_send.[ch]. Server now performs
6096 keepalive with all connections.
6098 * Added silc_task_get_first function into lib/silcutil/silctask.c
6099 to return the timeout task with shortest timeout. There was a bug
6100 in task unregistration that caused problems. TODO has been
6101 updated to include that task system must be rewritten.
6103 * The client library will now resolve the client information when
6104 receiving JOIN notify from server for client that we know but
6105 have incomplete information.
6107 * Rewrote parts of silc_server_remove_from_channels and
6108 silc_server_remove_from_one_channel as they did not remove the
6109 channel in some circumstances even though they should've.
6111 * Encryption problem encountered in server:
6113 The LEAVE command used to send the Channel Key packet to the
6114 router immediately after generating it. However, the code
6115 had earlier sent Remove Channel user packet but not immediately,
6116 ie. it was put to queue. The order of packets in the router
6117 was that Channel Key packet was first and Remove Channel User
6118 packet was second, even though they were encrypted in the
6119 reverse order. For this reason, MAC check failed. Now, this
6120 is fixed by not sending the Channel Key packet immediately but
6121 putting it to queue. However, this is more fundamental problem:
6122 packets that are in queue should actually not be encrypted
6123 because packets that are sent immediately gets encrypted
6124 actually with wrong IV (and thus MAC check fails). So, packets
6125 that are in queue should be encrypted when they are sent to
6126 the wire and not when they put to the queue.
6128 However, the problem is that the current system has not been
6129 designed to work that way. Instead, the packet is encrypted
6130 as soon as possible and left to the queue. The queue is then
6131 just purged into wire. There won't be any fixes for this
6132 any time soon. So, the current semantic for packet sending
6135 o If you send packet to remote host and do not force the send
6136 (the packet will be in queue) then all subsequent packets to the
6137 same remote host must also be put to the queue. Only after the
6138 queue has been purged is it safe again to force the packet
6141 o If you send all packets immediately then it safe to send
6142 any of subsequent packets through the queue, however, after
6143 the first packet is put to queue then any subsequent packets
6144 must also be put to the queue.
6146 Follow these rules and everything works fine.
6148 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Added new function silc_server_remove_clients_by_server to
6151 remove all client entries from ID list when the server connection
6152 is lost. In this case it is also important to invalidate all
6153 client entires as they hold the invalid server entry. This
6154 fixes fatal bug when server has lost connection and will reconnect
6157 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Made some sanity checks to silc_server_daemonise like to check
6160 whether the requested user and group actually exists.
6162 * Added sanity check to SKE's silc_ske_responder_finish to check
6163 that the public and private key actually is valid.
6165 * Invalidate the client's nickname when receiving Replace ID
6166 packet and the Client ID is being replaced. This means that the
6167 server will query the nickname if someone needs it (client)
6170 * Sort the ID Cache in client library when the ID Cache data
6171 has changed (needs sorting).
6173 * Do not allow for SILC client to create several connections to
6174 several servers. The client does not support windows right now
6175 and generating multiple connections causes weird behaviour.
6177 Irssi-silc client does support windows and can handle several
6178 connections without problems, see: www.irssi.org and SILC plugin.
6180 * Fixed some places where client was added to the IDList. The
6181 rule of thumb is following (in order to get everything right):
6182 If the client is directly connected local client then the
6183 `connection' argument must be set and `router' argument must be
6184 NULL to silc_idlist_add_client function. If the client is not
6185 directly connected client then the `router' argument must
6186 bet set and the `connection' argument must be NULL to the
6187 silc_idlist_add_client function.
6189 * The funtion silc_server_packet_send_local_channel actually did
6190 not check whether the client was locally connected or not. It
6191 does that now. Fixed a bug related to LEAVE command.
6193 * Fixed Remove Channel User payload parsing bug in server's
6194 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6196 * The server's silc_server_save_channel_key now checks also the
6197 global ID list for the channel as it might not be in the local
6198 list. Fixed a bug related to LEAVE command.
6200 * Is this the end of the [<unknown>] buglet that has been lurking
6201 around for a long time? A little for loop fix in server's
6202 silc_server_command_whois_parse that is used by both IDENTIFY
6203 and WHOIS command. At least, this was a clear bug and a cause
6204 of one type of [<unknown>] buglet.
6206 * WHOIS and IDENTIFY commands call the function
6207 silc_server_command_[whois/identify]_check function even if
6208 we are not router server.
6210 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6212 * Added --with-gmp configuration option. If set the GMP
6213 is always compiled in the SILC source tree. If not set then
6214 it is checked whether the system has the GMP3 installed. If
6215 it has then the GMP won't be compiled (the system's headers
6216 and library is used), if it doesn't have it then the GMP is
6217 compiled in the SILC source tree.
6219 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Changed RSA private exponent generation to what PKCS #1
6222 suggests. We try to find the smallest possible d by doing
6223 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6224 not security fix but optimization.
6226 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Added new config entry [Identity] to fork the server and run
6229 it as specific user and group. A patch from Bostik.
6231 * Imported Dotconf configuration library into lib/dotconf.
6232 This will be used to create the SILC configuration files later.
6233 It will appear in the distsribution after this commit.
6235 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * A big code auditing weekend happening. Auditing code for
6238 obvious mistakes, bugs and errors. Also, removing any code
6241 Removed files for being obsolete:
6243 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6244 inline in the file lib/silcutil/silcbuffer.h)
6246 o lib/silcutil/silcbufutil.c (the header has inline versions)
6248 Changed code to fix possible error conditions:
6250 o The buffer formatting routines now check that the destination
6251 buffer really has enough space to add the data. This applies for
6252 both buffer formatting and unformatting
6253 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6254 unformatting was changed to accomodate following rules:
6255 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6256 sent to the function while XXX_*STRING will not allocate or copy
6257 the data into the buffer. Instead it sets the pointer from the
6258 buffer into the pointer sent as argument (XXX_*STRING used to
6259 require that the pointer must be allocated already). This change
6260 makes this whole thing a bit more consistent and more optimized
6261 (note that the data returned in the unformatting with XXX_*STRING
6262 must not be freed now). The routines return now -1 on error.
6264 o Tried to find all code that use buffer_format and buffer_unformat
6265 and added return value checking to prevent formatting and
6266 especially unformatting errors and possible subsequent fatal
6269 o Changed ske->x and ske->KEY to mallocated pointers in
6270 lib/silcske/silcske.h. Fixed possible data and memory leak.
6272 o Added return value checking to all *_parse* functions. Fixed
6273 many memory leaks as well.
6275 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6276 so that buffer overflows would not happen. All code now also
6277 checks the return value as it can fail.
6279 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Added reconnection support to server if the normal server looses
6282 its connection to the router (for example if router is rebooted).
6283 The server performs normal reconnection strategy implemented
6284 to the server. Affected file silcd/server.c.
6286 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Added new packet type SILC_PACKET_SET_MODE that is used to
6289 distribute the information about changed modes (for clients,
6290 channels and clients channel modes) to all routers in the
6291 network. Updated the protocol specification accordingly.
6293 Added functions into silcd/packet_send.c and
6294 silcd/packet_receive.c: silc_server_send_set_mode,
6295 silc_server_set_mode.
6297 Added new files silcmode.[ch] into lib/silccore that implements
6298 the encoding and decoding of Set Mode Payload. Added new type
6299 SilcSetModePayload. Moved the definitions of different modes
6300 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6302 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Oops, a little mistake in server's connection authentication
6305 protocol. The protocol is not ended with FAILURE but with
6306 SUCCESS if the authentication is Ok. :) Affected file is
6309 * Implemented NICK_CHANGE notify handling in server in the file
6310 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6311 the local clients on the channel. After the changing nickname
6312 in router environment snhould work and the [<unknown>] nickname
6313 should appear no more.
6315 The silc_server_replace_id function that receives the Replace ID
6316 payload now sends the NICK_CHANGE notify type also in the file
6317 silcd/packet_receive.c
6319 * Changed WHOIS and IDENTIFY command to support the maximum amount
6320 of arguments defined in protocol specs (3328 arguments). This
6321 fixed a bug that caused problems when there were more than three
6324 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6326 * Added extra parameter, command identifier, to the
6327 silc_client_send_command so that explicit command identifier
6330 Changed that ID list routines uses specific command identifier
6331 when sending WHOIS/IDENTIFY requests to the server so that they
6332 can be identified when the reply comes back.
6334 Affected files lib/silcclient/command.[ch],
6335 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6337 * Added `sender' argument to silc_server_packet_send_to_channel
6338 to indicaet the sender who originally sent the packet to us
6339 that we are now re-sending. Ignored if NULL. Affected file
6340 silcd/packet_send.[ch].
6342 * Added some server statistics support in silcd/server_internal.h
6343 SilcServerStatistics structure and around the server code. Also
6344 send some nice statistics information when client is connecting
6347 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Fixed channel ID decoding in server's JOIN command reply in
6350 silcd/command_reply.c
6352 * Fixed braodcasting of replace ID payload to not to send it if
6353 we are standalone server in silcd/packet_receive.c.
6355 * Fixed all channel message sending routines to not to send
6356 packets to clients that has router set, since they are routed
6357 separately in the same function earlier. Affects file
6358 silcd/packet_send.c and all channel packet sending functions.
6360 * In USERS reply, res_argv[i] are not allocated, the table
6361 is allocated. Thus changed that free the table, not its
6364 * In server's whois_check and identify_check if the client is
6365 locally connected do not send any WHOIS commands - they are not
6368 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Fixed some minor bugs in client when sending WHOIS command. The
6371 arguments was in wrong order.
6373 * Removed statis function add_to_channel from server in
6374 silcd/command.c that was previously used with the joining but
6377 * Tested USERS command in router environment successfully with two
6378 routers, two servers and two clients.
6380 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6382 * Reorganized the USERS command and command reply in client library
6383 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6384 When the command is given by user we register a pending command
6385 callback that will reprocess the command after the reply has been
6386 received from the server. When reprocessing the packet we then
6387 display the information. Thus, the USERS information is displayed
6388 now in the command callback instead of in the command reply
6389 callback. The processing of the command is same as previously
6390 when server has sent the command reply in the JOINing process.
6392 * Added to USERS command in silcd/command_reply.c to join the client,
6393 we didn't use to know about, to the channel after we've created
6394 a client entry for it. Also, for clienet we did know already still
6395 check whether it is on the channel or not and add it if not.
6397 * Removed silc_server_command_join_notify as the function and its
6400 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Changed the client's pending command handling to the same as the
6403 server's pending command handling. It is also now possible to
6404 execute command reply functions from other command reply
6405 function as the function callbacks for commands and command
6406 replies are one and same. The pending commands are not static
6407 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6408 in client connection context. Thus, pending commands are server
6409 connection specific as it is convenient.
6411 Changed the function silc_client_command_pending and
6412 silc_client_command_pending_del and added new function
6413 silc_client_command_pending_check. Removed the
6414 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6417 * Added cmd_ident, current command identifier, to the client
6418 connection context in lib/silcclient/client.h to keep track on
6419 command identifiers used in command sending. Client's command reply
6420 function handling now supports the mandatory command identifiers.
6422 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6423 funtions in client to fully support pending command callbacks.
6425 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6426 as one of the arguments to the application in the command reply
6429 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6430 before first releasing SILC but came back. Now it is removed again
6431 and should come back nomore. The FORWARDED flag was used only
6432 by the JOINing procedure by forwarding the command packet to router.
6433 Now, the JOINing procedure has been changed to more generic (due
6434 to various router environment issues) and FORWARDED is not needed
6435 anymore for anything. The protocol specification is yet to be
6438 Now, removed silc_server_packet_forward from server and the flag
6439 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6441 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Renamed NAMES command to USERS command. The NAMES was named that
6444 due to historical reasons. Now it is renamed. Also, rewrote
6445 parts of the USERS command. The nickname list is not sent anymore
6446 by the server. Only Client ID and mode lists are sent in the USERS
6447 command. Changed this also to the protocol specification.
6449 The client now resolves the names and stuff after it receives
6450 the USERS list from the server when joining to the channel.
6452 * WHOIS and IDENTIFY commands has been changed to support multiple
6453 Client ID's per command. One can now search for multiple users
6454 in the network by sending only one WHOIS or IDENTIFY command.
6455 Changed the code and the protocol specifications.
6457 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6458 uses silc_server_command_whois_parse to parse the request. */
6460 * If normal server, do not parse the WHOIS and IDENTIFY requests
6461 before sending it to the router. Saves some time.
6463 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6465 * Fixed JOIN command on client library. Wrong number of arguments
6466 used to crash the client.
6468 * Added silc_server_channel_has_global function to check whether
6469 channel has global users or not.
6471 * Added silc_server_channel_has_local function to check whether channel
6472 has locally connected clients on the channel.
6474 * The silc_server_remove_from_one_channel now checks whether the
6475 channel has global users or not after given client was removed from
6476 the channel. It also checks whether the channel has local clients
6477 on the channel anymore. If it does not have then the channel entry
6478 is removed as it is not needed anymore.
6480 * The silc_server_notify now checks on JOIN notify whether the joining
6481 client is one of locally connected or global. If it is global then
6482 the channel has now global users on the channel and that is marked
6483 to the channel entry. Also, it now saves the global client to
6484 global list who is joining and JOINs it to the channel. This is
6485 for normal server, that is.
6487 Changed silc_server_send_notify_on_channel,
6488 silc_server_packet_relay_to_channel and
6489 silc_server_packet_send_to_channel check if we are normal server
6490 and client has router set (ie. global client) do not send the
6491 message to that client, as it is already routed to our router.
6493 * Implemented LEAVE notify type handling in silc_server_notify
6496 * Tested LEAVE command in router environment successfully. Tested
6497 with two routers, two servers and two clients.
6501 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6503 * Implemented SIGNOFF notify type handling in silc_server_notify
6506 * silc_server_remove_id now removes the client entry from all channels
6507 it has joined and thusly sends SIGNOFF notify type.
6509 * Rewrote the NAMES list generation in server by removing two excess
6510 loops. The lists are created now inside one loop.
6512 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * silc_server_remove_channel_user checks now also global list
6515 for channel and client.
6517 * silc_server_new_channel_user checks now both local and global
6518 list for channel and client. Fixed a bug in client id decoding.
6519 Used to decode wrong buffer.
6521 * silc_server_channel_message checks now both local and global
6522 list for channel entry.
6524 * Tested channel joining (hence JOIN) in router environment
6525 successfully. Tested with two routers, two servers and two
6528 * Tested channel message sending in router environment successfully.
6530 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Added silc_server_save_channel_key into server.[ch] to save the
6533 received channel key in Channel Key payload processing. It is
6534 also used in JOIN command reply handling.
6536 Equivalent function silc_client_save_channel_key added into
6537 client.[ch] into client library.
6539 * Changed JOIN command reply to send information whether the channel
6540 was created or not (is existing already) and the channel key
6541 payload. Changed protocol specs accordingly.
6543 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6544 the request was sent by ID and not by nickname. Crashed on
6547 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6550 now correctly save the received data.
6552 * silc_server_free_sock_user_data now notifies routers in the
6553 network about entities leaving the network.
6555 At the same time implemented functions silc_server_remove_id
6556 and silc_server_send_remove_id to receive and send REMOVE_ID
6557 packets. The packet is used to notify routers in the network
6558 about leaving entities. The ID removed will become invalid in
6561 * Added function silc_idlist_del_server into server. Removes and
6562 free's server entry from ID list.
6564 * silc_server_private_message function now checks, if we are router,
6565 that the destination ID really is valid ID, naturally.
6567 * In router when NEW_ID packet is received (for new client) the
6568 hash of the Client ID is saved in the ID Cache but the
6569 client->nickname is set to NULL, instead of putting the hash
6572 IDENTIFY command now also checks that client->nickname must be
6573 valid. If it is not if will request the data from the server who
6574 owns the client. Added new function
6575 silc_server_command_identify_check.
6577 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6578 to set the command to already allocated Command Payload.
6580 * Tested private message sending in router environment with two
6581 routers, two servers and two clients. Fixed minor bugs and now
6584 * Fixed segfault from client's NAMES command. Used to crash if
6587 * Forwarded packets must not be routed even if it is not destined
6588 to the receiver. Changed server code comply with this.
6590 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Added `require_reverse_mapping' boolean value to ServerParams
6593 structure. If TRUE (not default) the server will require that
6594 the connecting host has fully qualified domain name.
6596 If the reverse mapping is not required and hostname could not be
6597 found the IP address is used as hostname.
6599 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Implemented version string checking to both client and server.
6602 The check is incomplete currently due to the abnormal version
6603 strings used in development version of SILC.
6605 * Changed all command functions in server to use the new
6608 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Changed char *data to unsigned char *data in ID Cache system to
6611 support binary data as ID Cache data. Changed code to support
6612 binary data in lib/silccore/idcache.c.
6614 * Renamed silc_server_packet_relay_command_reply to
6615 silc_server_command_reply as it is normal packet receiving
6616 function. Rewrote the function to accept command replys for
6617 servers and not only for clients.
6619 * Mark remote router always as registered server if we are connecting
6620 to it. Otherwise, commands sent by the router to us are ignored.
6622 * All ID List find routines now returns the ID Cache Entry pointer
6623 as well if requested.
6625 * WHOIS command works now in router environment, tested with two
6626 routers, two servers and two clients.
6628 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6629 in router environment (as it is almost equivalent to WHOIS) but
6630 hasn't been tested thoroughly. Added new functions:
6632 silc_server_command_identify_parse
6633 silc_server_command_identify_send_reply
6634 silc_server_command_identify_from_client
6635 silc_server_command_identify_from_server
6637 * Disabled route cache adding because adding two different ID's with
6638 same IP replaces the old cache entry thus giving wrong route.
6639 The entry->router->connection is always the fastest route anyway
6640 so route cache may not be needed. Of course, new routes maybe
6641 established after receiving the ID when the entry->router->connection
6642 might not be anymore the most optimal.
6644 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Add route cache for received ID for fast routing.
6648 * Added silc_server_packet_route to route received packet on router
6649 that is not destined to us.
6651 * Renamed silc_server_get_route to silc_server_route_get.
6653 * Added id_string and id_string_len fields into SilcServer to
6654 include encoded ServerID for fast comparing without excess
6655 encoding of the ID's.
6657 * Cleaned up WHOIS command on server side. Added following static
6660 silc_server_command_whois_parse
6661 silc_server_command_whois_check
6662 silc_server_command_whois_send_reply
6663 silc_server_command_whois_from_client
6664 silc_server_command_whois_from_server
6666 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6667 arguments in command replies. All command functions should be
6668 updated to use this macro.
6670 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Minor typo fixes on command reply handling on server.
6674 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added silc_server_command_add_to_channel internal routine to add
6677 the client to the channel after router has created the channel and
6678 sent command reply to the server.
6680 * Added generic silc_server_send_command to send any command from
6683 * Use static buffer with ID rendering instead of duplicating data.
6685 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Fixed a channel user mode bug when joining to a channel server gave
6688 everybody channel founder rights, oops.
6690 * We mark ourselves as the router of the incoming server connection
6691 if we are router ourselves. This way we can check in some packet
6692 sending functions whether it is locally connected server. For
6693 incoming router connections we put NULL.
6695 * For router sending packets locally means now always sending the
6696 packet cell wide; to local clients and local servers. For normal
6697 server sending packet locally means sending it to only local
6700 * Fixed the JOIN command to really work in router environment. If the
6701 channel is created it is always created by the router. Router is
6702 also responsible of making the initial joining to the channel,
6703 sending JOIN notify to the sending server and distributing
6704 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6705 does not exist server doesn't do anything else but forward the
6706 command to the router which performs everything.
6708 * Added silc_server_send_channel_key function to send the Channel Key
6711 * Added silc_server_create_channel_key to create new channel key. The
6712 channel key is now re-generated everytime someone joins or leaves
6713 a channel, as protocol dictates. Note: channel->key_len is the
6716 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6719 packet_receive.[ch] to separate packet sending and receiving
6720 routines. The server.[ch] now includes everything else including
6721 actual packet processing (writing and reading data) and other
6724 Renamed silc_server_private_message_send_internal to
6725 silc_server_send_private_message. The routine is still though
6726 used only to relay private messages as server does not send
6727 private messages itself.
6729 Renamed silc_server_new_channel to silc_server_create_new_channel
6730 and added new function sicl_server_new_channel that handles the
6731 incoming New Channel packet. Added also new sending function
6732 silc_server_send_new_channel to send New Channel Payload.
6734 * Added new function silc_server_notify to process incoming notify
6735 packet to the server/router. Server may then relay the notify
6736 to clients if needed.
6738 * Added new function silc_server_new_channel_user to process incoming
6739 New Channel User packet. Router will redistribute the packet and
6740 send JOIN notify to its local clients and locally connected servers
6741 if needed. Normal server will send JOIN notify to its local client
6742 on same channel when received this packet. Added also corresponding
6743 sending function silc_server_send_new_channel_user to sent the
6746 * Added boolean route argument to send_notif_to_channel and
6747 packet_send_to_channel functions to attempt to route the packet
6748 if it is TRUE and send only locally if it is FALSE.
6750 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * silc_server_replace_id now broadcasts the received replace ID
6753 packet if it is not broadcast packet already. The router must
6754 broadcast to inform other routers about changed ID.
6756 * Added backpointer to server's router into SilcServer context in
6757 silcd/server_internal.h.
6759 * Fixed silc_server_packet_broadcast to send correct broadcast
6762 * The channel key is now distributed to the local client as soon
6763 as it is received from the router (in router environment) so that
6764 no other packet may be sent for the channel until client has
6767 * silc_server_remove_channel_user now broadcasts the received
6768 Remove Channel User packet if it is not broadcast packet already.
6769 The router must broadcast to inform other routers about removed
6772 * Added users field into SilcPacketContext that is a reference count
6773 of the context. One can increase the reference count by calling
6774 silc_packet_context_dup which is now changed to just increase the
6775 reference count instead of duplicating the data. The reference
6776 count is decresed by calling silc_packet_context_free that will
6777 free the data after the reference count hits zero.
6779 For now on the packet context and everything allocated into it
6780 (including the raw packet from network) must be freed by calling
6781 the new silc_packet_context_free function. Added also new function
6782 silc_packet_context_alloc that must be used now to allocate the
6783 context. This also means that if a routine is asynchronous from
6784 silc_[client/server]_packet_parse_type the packet context must
6785 be duplicated by calling silc_packet_context_dup. Otherwise it
6786 gets free'd after silc_[client/server]_packet_parse_type returns.
6787 Also, one must remember that if packet is duplicated then its
6788 reference count must be decresed by calling the free function as
6789 many times as it was duplicated.
6791 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6792 from both client and server.
6794 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Made joining to a channel working in router environment.
6798 * Cleaned up JOIN command on server side and create function
6799 silc_server_command_join_channel internal routine to make the
6802 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Changed silc_command_pending list to SilcDList. Also, added
6805 `ident' field to SilcServerCommandPending structure to identify
6806 the reply and to call correct callback.
6808 Added silc_server_command_pending_check function to replace the
6809 corresnponding macro. The silc_command_pending list is not
6812 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6813 to set identifier to previously allocated Command Payload. It
6814 is used to set identifier for command when resending Command
6817 * Added silc_command_payload_encode_payload to encode Command
6818 Payload buffer from SilcCommandPayload structure.
6820 * Added silc_argument_payload_encode_payload to encode Argument
6821 payload buffer from SilcArgumentPayload structure.
6823 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Changed WHOIS command to support router connection on server side.
6826 The whois request is always sent to router unless the server is
6827 standalone server. After server has received the reply from the
6828 router will it send the reply to the client.
6830 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6831 broadcast received broadcast packet. The function is used only
6832 by router. The broadcast packet is always sent to the router's
6835 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6836 render given ID to printable string, for log files for example.
6838 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Made basic router to router connections working. At least they
6841 can now connect to each other but nothing really works the way
6842 they are supposed - yet.
6844 * Added new initiator token to RouterConnection configuration
6845 file in silcd/serverconfig.[ch]. It is used to tell whether we
6846 are the initiator to the remote router or whether we'll expect
6847 the other end to connect.
6849 * Moved registering of listener task to silc_server_init, hence
6850 the server starts listenning as soon as it is run, even if it
6851 does not have connections to other routers. Let's see how well
6854 * Changed default connection retry timeouts for more suitable in
6857 * Removed cipher and such arguments from silc_idlist_add_client
6858 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6859 Added new function silc_idlist_add_data to add the keys and stuff
6862 * Added SilcIDListData structure and added it to SilcClientEntry
6863 and SilcServerEntry as their first field in the structure. This
6864 way we can explicitly cast the ID entries to the SilcIDListData
6865 structure and get common data for the entries. In past, we had
6866 to first check what type of connection it is and then cast it to
6867 correct ID entry type. Now, we can directly cast the opaque
6868 pointer to the SilcIDListData (no matter what ID entry it actually
6869 is) and get the data needed.
6871 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6874 in some circumstances even if threre were timeout tasks, though not
6875 IO tasks, but tasks anyway. Now fixed.
6877 * Defined SilcServerConnection structure to hold connection specific
6878 stuff about directly connected servers and routers. The definition
6879 is currently in silcd/server_internal.h. I thought about having
6880 a bit more important role fro this struct but for now it is used
6881 only when connecting to other server (or router actually).
6883 * Added connecting retry support in server when connecting to
6884 router(s). The retry feature implement exponential backoff
6885 algorithm. Also, added SilcServerParams structure to hold default
6886 parameters for server. For now, it include these retry settings
6887 and are hard coded. After server is moded to be as Silc Server
6888 Library this structure will be more important.
6890 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Changed client librarys channel->clients table to SilcList and
6893 changed code accordingly.
6895 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Changed client's channel table to SilcList and changed code
6898 accordingly. Also changed SilcChannelClientEntry to include back-
6899 pointer to the channel so that client entry can use that structure
6900 as list as well and we have fast cross-reference to the channel.
6901 This change dramatically decreased the complexity of channel
6902 handling with client entry and vice versa (removed one extra
6903 loop when searching for channel entry from many functions).
6905 * Changed server->sim from table to SilcDList and changed code
6908 * NAMES command can now be used from user interface. It will show
6909 the user list on the channel, neatly.
6911 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6912 Code now saves realname of the user if it becomes available.
6914 * Renamed configure.in to configure.in.pre and made ./prepare
6915 script to automatically add correct version string to
6916 configure.in which it creates from configure.in.pre.
6918 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * NAMES command reply now shows users mode with the nickname when
6923 * Moved silc_client_ch[u]mode[_char] functions from
6924 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6925 place sucks, they are utility functions and should be in some
6928 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6930 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6933 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Added TRQ (efficient deque and list library) into lib/trq. This is
6938 a very good list library that is currently used in the SILC. Defined
6939 SilcList API over the library because I didn't like the API very
6940 much. See lib/trq/silclist.h for the API and examples of how to
6941 use the API. Fixed various places in the code to use the new
6942 SilcList API. The SilcList is meant for lists that has a structure
6943 already defined as a list. It is not suitable to add just some
6944 context to the list (in TRQ, the context is the list actually).
6946 So, I defined SilcDList that can be used for the purpose where
6947 predefined list structure does not exit. This can be used as
6948 such list. Now some context just can be added to the SilcDList.
6949 Currently this list is not used in the SILC just yet, though there
6950 are a lot places where this can replace dynamically allocated
6951 tables and I will fix these places, later, to use SilcDList.
6952 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6953 and use TRQ internally).
6955 Also fixed some annoying warning messages that the original TRQ
6956 code generated. Also minor changes to TRQ's Makefile.in.
6958 * Added support for querying by Client ID to both WHOIS and
6959 IDENTIFY commands into server, as required by the protocol.
6961 * Removed method function pointers from SilcBuffer structure. They
6962 weren't used to anything and just increased the context size for
6963 no good reason. This change also made silc_buffer_alloc and
6964 silc_buffer_free functions inline functions.
6966 * Disabled command flooding detection support until it's fixed so
6967 that it accepts commands in but does not execute them more than once
6970 * Added silc_net_localhost(), to return local hostname, into
6971 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6972 that must be initialized before calling silc_client_init.
6974 * Added new function: silc_server_send_notify_on_channels to send
6975 notify messages to all channels client has joined. It is assured
6976 that the message is sent only once per client.
6978 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6979 lib/silcutil/silcutil.[ch] as silc_format function. The new
6980 function is generic and is used by server as well, not only by
6981 the logging routines.
6983 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6984 the provided version string was not acceptable. Added new function:
6985 silc_ske_check_version into lib/silcske/silcske.h. The function
6986 must be implemented by the application (client or server) and it
6987 does not reside in the SKE library. The function checks the version
6988 string remote end sent.
6990 * Added back pointers (to opaque context and to SilcSocketConnection)
6991 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6993 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6994 duplicate packet context structure.
6996 * Changed `notify' client operation to send same arguments as client
6997 receives from server except for ID's. ID's are mapped to correct
6998 ID entry and that is returned. Also, if channel entry is not sent
6999 by server but the notify is for channel the channel entry is sent
7000 to application (otherwise application doesn't know that it is for
7001 channel (library gets it from packet's Destination ID)).
7003 * Added silc_client_remove_from_channels into client library to
7004 remove a client from all channels it has joined to. Used when
7005 received SIGNOFF notify from server. Added also new function
7006 silc_client_replace_from_channels to replace old ID entry with
7007 new ID entry on all channels. Used when received NICK_CHANGE
7010 * Fixed ID Cache list handling in silc_idlist_get_client in
7011 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7012 to get (or query) client by ID.
7014 * Updated TODO list.
7016 * Added connection authentication status message defined by the
7017 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7018 support for these into the code in client and server side.
7020 * Added generic function silc_client_send_command to send any command
7021 with variable argument list. Application should use this function
7022 to send commands if the command functions provided by the library
7023 does not suite for the application's user interface needs.
7025 * Added new `failure' client operation. Application is notified about
7026 received failure packet if client is executing a protocol. In this
7027 case the protocol's execution has failed.
7029 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7030 is required by the protocol.
7032 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7033 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7036 * Added status flag to SilcSKE object to indicate realtime status
7037 of the SKE protocol.
7039 * Application receives now exactly same command reply arguments as
7040 the library receives from server. However, if ID is received the
7041 corresponding ID entry is returned to the application (eg. Client
7042 ID is mapped to correct SilcClientEntry entry and that is returned).
7043 Changed command_reply client operation due to this change.
7045 * Changed all ID's in commands and in command replys as ID Payloads.
7046 Change affected both client and server side codes.
7048 All ID's sent in SILC network (with execption of ID's in SILC
7049 Packet header) are sent in ID Payload to support variable length
7052 * Server now notifies nick changes and notifies all clients on
7053 the channels about the new nickname (about the new Client ID,
7056 * Implemented CMODE command to change channel modes. Supports all
7057 channel modes defined by the protocol specs except ban and invite
7058 lists. (Also, private channel key mode is supported but support for
7059 setting private channel key in client is missing, thus, this mode
7060 has no effect on client side (except that server requires that the
7061 client uses private channel key and normal channel traffic does not
7064 Also, invite mode works per se, but INVITE command does not work
7065 yet correctly, so you can set channel as invite only channel but
7066 inviting clients to the channel does not work (it is yet to be
7067 thought what's the best way to do it).
7069 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7070 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7071 Implemented CUMODE command to change user's mode on the channel.
7072 Supports all modes defined by the protocol specs.
7074 * Added NAMES command reply to return users modes on the channel.
7076 * Removed unnecessary and slow ciphers from lib/silccrypt.
7078 * Set SO_KEEPALIVE option to connection sockets by default.
7080 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7082 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7083 redefined the Notify Payload into protocol specs.
7085 * Added silc_id_payload_parse_id to get ID directly from raw
7088 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7091 accept searching by Client ID as well.
7093 * Added support for LEAVE and SIGNOFF notify types in client library.
7095 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7096 to parse ID Payload from raw data.
7098 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7100 * Added flags parameter into silc_ske_assemble_security_properties
7101 function in lib/silcske/silcske.[ch].
7103 * Changed notify client operation to fit better for notify messages
7104 sent by server. The notify payload received from server is now
7105 passed to the application (after parsing it to SilcNotifyPayload).
7106 It is application's responsibility to retrieve the arguments
7107 from the payload and show the message the way it wants. The message
7108 sent by server is implementation specific.
7110 * Changed public keys to comply with the protocol specification.
7111 Old public keys are not supported anymore and are not compatible.
7113 * Removed nickname from Channel Payload as the latest draft removed
7114 it. The client must resolve the nickname from the NAMES command
7115 reply received when it joined the channel.
7117 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7119 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Fixed some errors in protocol specification drafts.
7123 * Created lib/silccore/silcnotify.c to implement Notify Payload
7124 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7125 generic payloads described by protocol specifications. The file
7126 includes implementations for ID Payload and Argument Payload.
7128 * Changed Command Payload implementation to use the new Argument
7129 Payload. Changed command_xxxx_payload to command_payload_xxxx
7130 to comply with SILC coding conventions.
7132 * Added suppport for Argument Payload handling in Notify Payload
7133 implementation as protocol requires it. Added the new support
7134 into server and client lib as well.
7136 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Added support for multiple nicknames on same channel. [n] is
7139 added locally to the nickname if there are more than one same
7140 nicknames on the channel.
7142 * Server now sends all nicknames that matched WHOIS request.
7143 Client also shows the list received from server.
7145 * Added TOPIC command to client side. User can now set and show
7146 current topic on channel.
7148 * Added MOTD command to client and server. Also, server sends the
7149 motd when client connects to the server.
7151 * Changed version strings to comply ISO 8601.
7153 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7155 * Fixed protocol error handling in client library. It should now
7156 cope even if the SKE fails for some reason.
7158 * Made new protocol specification drafts for submitting to IETF.
7160 * Implemented TOPIC command to server in silcd/command.c.
7162 * Added two new notify types into lib/silccore/silcnotify.h:
7163 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7164 notify nickname change and topic setting/change on a channel.
7166 * API change of command_reply operation in client library. The
7167 application gets now the status type received from server as well.
7169 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7173 * Cras fixed and optimized the packet handling even further and
7174 it should work now. Minor change to the prototype of function
7175 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7177 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Added new function into lib/silcutil/silcschedule.[ch]:
7180 silc_schedule_with_fd to select() a specified fd. The function
7181 returns after timeout expires or data arrives or goes. The
7182 function is used by packet routines to wait that all data is
7183 received from network.
7185 * Fixed data reading from network in lib/silccore/silcpacket.c.
7186 The code now assures that all data is read from the fd and then
7187 continues packet processing. This was a bug fix since the code
7188 used to drop some data in some circumstances.
7190 * Added new function into lib/silcclient/client.[ch]:
7191 silc_client_start_key_exchange to start key exchange after
7192 connection has been established to server. The code internally
7193 now uses this funtion but its main purpose was to provide it
7194 for applications that perform their own connecting. After
7195 application has created a connection it merely calls this
7196 function to start the key exchange between client and server.
7197 The library takes care of everything else after that.
7199 Updated also lib/silcclient/README to explain the usage of
7202 * Do not send to application information that connection has
7203 been established. Application gets notified it by connect
7206 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7208 * Applied cras's patch to add silc_schedule_one function. The
7209 function runs scheduler once and returns.
7211 * Fixed the scheduler after cras messed it up. The timeout
7212 handling works now as it's supposed to work.
7214 * Added into lib/silccore/ silcnotify.h to include notify
7215 message types support. Changed silc_server_send_notify*
7216 functions, in server.[ch], to support those new notify types.
7217 Added the support for the notify types into client library,
7218 as well. Added new notify client operation into ops.h in
7221 * Changed silc_server_packet_send_to_channel to send normal
7222 packets instead of just channel message packets. The function
7223 is now used to send the notify packets to channels. It is not
7224 used to send channel message packets anymore, as server never
7227 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7228 va_arg()s as it seems to require it nowadays. I guess, if SILC
7229 is compiled with older va_arg() the new code should work anyway.
7231 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Splitted core library. Core library (lib/silccore) includes
7234 now only SILC protocol specific core (and common) components.
7235 Created new utility library (lib/silcutil) that includes more
7236 generic purpose stuff. The stuff for util library was taken
7237 from the old core library. This was minor and easy split.
7239 * Created SILC Client Library (lib/silcclient) that includes
7240 implementation of the SILC client without user interface. This
7241 was major move from silc/ directory. The code has been changed
7242 so that it is transparent towards the user interface. The
7243 silc/ directory includes now the same user interface as before
7244 and it uses the new client library. Read lib/silcclient/README.
7245 Basicly, the client library performs everything else related
7246 to SILC except user interface handling. Also, configuration
7247 files are considered to be part of user interface and library
7248 does not handle them.
7250 This change also changed a lot of structures, function naming etc.
7251 Most important change was that SilcClientWindow object was
7252 renamed to SilcClientConnection in the client library. Created
7253 also new file lib/silcclient/ops.h. Also added new files
7254 silc/local_command.[ch] and silc/client_ops.[ch].
7256 All these changes were made to make it easier for user interface
7257 designers to create what ever user interface for the SILC client
7260 It is also expected that the server will be moved to lib
7261 directory as well and SILC Server Library will be created;
7262 sometimes in the future.
7264 * Removed Local commands from lib/silccore/silccommand.h as
7265 they are application specific and new client library does not
7266 handle any of those anymore.
7268 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7269 old client implementation in silc/.
7271 * Added support for callback functions in SILC_LOG_* macros.
7272 Application can now set its own callbacks that will be called
7273 instead of using the default functions that will always print
7274 the debug messages to stderr (or stdout). Also, debugging can
7275 now be disabled by setting silc_debug to FALSE and re-enabled by
7276 setting it to TRUE. Note, that logging will still work even
7277 if debugging is disabled.
7279 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7280 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7281 silc_log_reset_debug_callbacks.
7283 * To enable debugging in silc client one must give now -d
7284 option on command line.
7286 * Changed silc_schedule_init to automatically allocate task queues
7287 if they are not allocated before calling it.
7289 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Added GMP 3.1 into math library.
7293 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7296 a channel in SILC network. The packet is used by servers and
7297 routers to notify other routers that user has left a channel.
7298 This little feature was missing until now. Added the feature
7299 to protocol specification as well.
7301 Added functions: silc_server_send_remove_channel_user and
7302 silc_server_remove_channel_user into server.[ch].
7304 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7305 lib/silccore/silcpacket.h. However, they are not implemented
7308 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Fixed joining to a channel and sending channel messages
7311 between server and router. The channel message sending should
7312 now work inside a cell.
7314 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Fixed the private message sending between server and router.
7317 The private message sending should now work inside a cell.
7319 * Added silc_server_replace_id into server.[ch] to replace
7320 existing ID in the SILC network.
7322 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7323 and silc_idlist_replace_server_id into idlist.[ch] in server.
7325 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Fixed the server to server connections. Server can again now
7328 connect to router. Router to router connections probably does
7331 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Added dynamic protocol registering support. Now protocols can
7334 registered and unregistered on the fly. Patch by cras.
7336 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Added lib/contrib directory to hold routines that some platforms
7339 don't have but are needed by SILC.
7341 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7342 into lin/contrib to provide getopt() and getopt_long() for
7343 those who don't have it.
7345 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7347 * Added AWAY command to client. When away message is set and
7348 client receives a private message packet the client automatically
7349 replies to the sender with the away message.
7351 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7352 bug seemed to be the cause of recent problems when compiling
7355 * Added version detection support to SKE protocol specification
7356 and added the new changes to the SKE implementation as well.
7357 There were other minor changes in the SKE protocol as well.
7359 Many changes in lib/silcske/silcske.[ch] and in
7360 lib/silcske/payload.[ch].
7362 * Added ^U functionality, clear input line. Patch from cras.
7364 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7366 * Mainly small bugfixes on core library. Fixed some debugging
7367 logging and buffer overflow in silclog.c.
7369 * Updated config.sub and config.guess on the distribution tree.
7371 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7373 * Added command lagging support in server. Client may execute
7374 commands now only once in two seconds.
7376 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7378 * Optimized packet reception. MAC computation and checking is now
7379 also more optimized. A lot previously duplicated code is now
7380 used as generic by both client and server.
7382 * Fixed key pair generation in clientutil.c
7384 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Added into lib/silccore/silcbufutil.[ch] new function;
7387 silc_buffer_realloc.
7389 * Moved generic packet sending/encryption functions to
7390 lib/silccore/silcpacket.[ch] from client and server. Some
7391 rewriting of the functions.
7393 * Moved all generic packet reception/decryption functions to
7394 lib/silccore/silcpacket.[ch] from client and server. The
7395 packet processing is now much cleaner in both client and server.
7396 These were major changes in both client and server.
7398 * Created many common functions in server to do packet sending.
7399 Previously code were duplicated a lot, this has been removed
7402 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7404 * Rewrote major parts of the ID cache system. Don't know
7405 whether it is better now or not but at least the API is more
7408 * Major rewrite on ID cache stuff on client because of the ID
7409 cache API changes. Added idlist.c to client.
7411 * Also major rewrite on ID cache stuff on server as well.
7412 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7413 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7414 in hand, instead they are all put into the ID cache system now.
7415 All server_idlist_* routines uses ID cache now instead of
7416 traversing its own lists (those lists does not exist anymore).
7417 SilcIDList though still exists. Also, SilcXXXEntry's are
7420 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Finally made the SKE implementation compliant to the protocol
7423 specification. All mp integers are now binary encoded as
7424 opposed being HEX encoded.
7426 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7429 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7430 functions: silc_[encode/decode]_pem. Also added function
7431 silc_encode_pem_file to PEM encode with newlines ('\n') for
7434 * SILC public keys are now encoded either PEM or binary. Same
7435 option is for private keys as well. By default private keys
7436 are binary encoded and public keys PEM encoded. Silly HEX
7437 encoding were removed.
7439 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7440 function to create fingerprints.
7442 * Fixed a bug in SHA1; does not change the original data anymore.
7444 * Partly implemented INFO command on client and server side.
7445 Fixed CLEAR command. Changes to SERVER command; show current
7446 server(s) when giving command without arguments. Added
7447 VERSION command to client.
7449 * Added check to server that unregistered connections cannot
7450 execute commands (unless it is specificly allowed).
7452 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Fixed screen refresh.
7456 * Fixed channel joining bug from client. On some circumstances
7457 client tried to join to a channel it had already joined.
7459 * Added public key verification process into client's protocol.c.
7460 The client now verifies the public key from user and saves
7461 it into ~./silc/serverkeys/ directory.
7463 Added into: clientutil.[ch]: silc_client_verify_server_key.
7465 * Changed SKE protocol's silc_ske_initiator_finish function
7466 to accept callback function that verifies the received public
7467 key. Removed old silc_ske_verify_public_key function.
7469 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7471 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7472 silc_pkcs_private_key[_data]_set.
7474 * Made the password and public authentication more cleaner in
7475 server's protocol.c.
7477 * Removed historic and obsolete protocol `channel_auth' from
7478 both client and server.
7480 * Removed wrong way of sending command status messages from
7481 server to client in server's command.c. The old way violated
7482 protocol specification.
7484 Changes to silccore/silccommand.[ch]: removed
7485 silc_command_encode_status_payload -> not needed anymore,
7486 changed silc_command_encode_payload_va to accept extra
7487 argument on variable argument list. The argument type must
7488 now be provided to the function. Also, added new function:
7489 silc_command_encode_reply_payload_va which is same as
7490 normal command_encode_payload_va except command status type
7491 is provided as extra argument.
7493 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added ~./silc directory handling. The directory includes the
7496 public and private keys for the client.
7498 Added silc_client_check_silc_dir, silc_client_create_identifier
7499 and silc_client_load_keys.
7501 * Implemented SILC protocol compliant public key. Added public
7502 and private key saving to and loading from files.
7504 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7505 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7506 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7507 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7508 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7510 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7511 silc_pkcs_load_[public/private]_key.
7513 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added silc_server_get_route (route.[ch]) to get connection
7516 data for the fastest route for given ID.
7518 * Implemented INVITE command on client and server. The command
7519 were re-defined in the SILC Protocol Specification and the
