1 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Don't change the topic if olod topic is same as new one.
4 Affected file is silcd/packet_receive.c.
6 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Added cross-reference support to the SILC Documentation
9 generator. All types across all HTML files are now cross-
10 referenced. Affected files util/robodoc/generator.c and
11 scripts/silcdoc/silcdoc.
13 * Added file lib/silcutil/silctypes.h to include all the
14 arithmetic type definitions and some macros. Removed
15 includes/bitmove.h and moved macros to silctypes.h.
17 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
21 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Added `type' argument to silc_id_payload_parse_id function which
24 now returns the type of the ID to the sent pointer. Affected
25 file is lib/silccore/silcid.[ch].
27 * Added check for CMODE_CHANGE notify type that mode change is
28 allowed by the sender. Affected file silcd/packet_receive.c.
30 * Added check for CUMODE_CHANGE notify type that mode change is
31 allowed by the sender. Affected file silcd/packet_receive.c.
32 Added the ID type as CUMODE_CHANGE notify type as argument
33 to the `notify' client operation. Affected files are
34 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
36 * Added function silc_client_add_server to the client library.
37 Added support for resolving also channel and server info when
38 received unknown entity in notify packet. Affected files are
39 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
41 * Added function silc_command_get_status to return the command
42 status from the command reply's argument payload. Affected files
43 are lib/silccore/silccommand.[ch].
45 * Added check for KICKED notify type that the kicking is
46 allowed by the client. Affected file silcd/packet_receive.c.
48 * Created function silc_get_input which can be used to get input
49 (echo on or off) from user on command line. Affected files are
50 lib/silcutil/silcutil.[ch].
52 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
54 * Optimized silc_server_packet_relay_to_channel function.
55 Added new function silc_channel_message_payload_encrypt which
56 can be called directly if channel message payload needs to
57 be encrypted and is already encoded (no need to call _encode
58 function). Packet relaying is now done by router without any
59 extra memory allocations. Affected files are
60 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
63 * Fixed the INVITE notify handling. It took wrong arguments
64 as invite list and invite delete. Affected file is
65 silcd/packet_receive.c.
67 * Added check for TOPIC_SET notify type that the topic change is
68 allowed by the client. Affected file silcd/packet_receive.c.
70 * Added check for INVITE notify type that inviting is allowed by
71 the client. Affected file silcd/packet_receive.c.
73 * Changed the silc_server_client_on_channel to return the
74 SilcChannelClientEntry as well. Moved the function
75 silc_server_check_cmode_rights to server_util.[ch].
76 Affected files are silcd/server_util.[ch], silcd/command.c.
78 * Added function silc_server_check_umode_rights to check whether
79 changing client's user mode is allowed. Added check for
80 UMODE_CHANGE notify type that the umode change is allowed
81 by the client. Affected files are silcd/server_util.[ch],
82 silcd/packet_receive.c and silcd/command.c.
84 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
86 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
87 ID length. It ignored that ID can be IPv6 based as well.
88 Affected file lib/silccore/silcpacket.h.
90 * Fixed the silc_id_id2str and silc_id_str2id to take the
91 IPv6 address offset's into consideration. Affecte file is
92 lib/silccore/silcid.c.
94 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
96 * Fixed the internal Unix scheduler functions to check for
97 NULL context they may receive. The affected file is
98 lib/silcutil/unix/silcunixschedule.c.
100 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
102 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
103 can specify different directory with --home command line
104 parameter. Affected files irssi/src/silc/core/client_ops.c,
107 * SILC-specific commands aren't now executed if the active server
108 isn't of SILC-type, so there won't be problems with having
109 IRC and SILC protocol support in same client. Affected files
110 irssi/src/silc/core/silc-channels.c, silc-servers.c,
113 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
115 * Improved the signal support in SILC Schedule. Added new
116 function silc_schedule_signal_call which is used by application
117 to mark a signal to be called. It is now safe to perform
118 any kind of tasks in signal callbacks since it is guaranteed
119 that the application specified signal callback is called
120 after the signal is over. Affected files are
121 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
123 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Added `name' field to SilcChannelPrivateKey to represent
126 application given name for the key. Moved also the context from
127 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
128 Added the `name' argument also to the function
129 silc_client_add_channel_private_key.
131 Added function silc_client_current_channel_private_key to set the
132 current channel private key in use.
134 Added "change" command to KEY command which can be used to change
135 the current channel private key. Bound the command also to
138 Also affected files lib/silcclient/client_channel.c,
139 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
141 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
143 * Added silc_rng_get_byte_fast function in to the
144 lib/silccrypt/silcrng.[ch].
146 * Changed the interface of silc_packet_assemble and the
147 silc_packet_send_prepare. If silc_packet_assmble is now
148 called the application does not call silc_packet_send_prepare
149 because the library will call it automatically. These
150 interfaces now also return a reference to the outgoing buffer
151 which includes the assembled packet, which the application can
152 use to encrypt the packet.
154 Affected files are lib/silccore/silcpacket.[ch],
155 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
156 silcd/packet_send.c, server_backup.c and packet_receive.c.
158 * Fixed a packet sending bug on very high load, where outgoing
159 packet queue wasn't handled correctly and packets got corrupted.
160 Affected files are lib/silcutil/*/silc*sockconn.c,
161 lib/silcclient/client.c and silcd/server.c.
163 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
165 * Added macro SILC_PACKET_DATALEN which can be used during
166 packet assembling to check whether the data to be added to
167 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
168 len is truncated until it fits it.
170 Added checks for maximum length of channel message payload and
171 private message payload also.
173 Added checks for maximum packet length in server and in
176 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
177 lib/silcclient/client.c, lib/silccore/silcchannel.c and
178 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
179 lib/silcclient/client_prvmsg.c.
181 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
183 * Added silc_server_packet_queue_purge call to the
184 silc_server_disconnect_remote to assure that all data in the
185 queue before disconnecting is sent to the network. Affected
188 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
190 * Added the deleting of server's own ID cache entry to the
191 silc_server_free function. Free also everything else that
192 has been allocated in silc_server_init. The affected file
195 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Added functions silc_parse_version_string, silc_version_to_num,
198 and silc_ske_parse_version to parse SILC protocol style version
199 strings. Affected files lib/silcutil/silcutil.[ch] and
200 lib/silcske/silcske.[ch].
202 * Added new configuration params: version_protocol, version_software
203 and version_software_vendor to specify what version the remote
204 host must at least be to be able to connect to server. The vendor
205 string can be regex matched too. Added new function
206 silc_server_connection_allowed to check maximum number of allowed
207 connections, and allowed versions for incoming connections.
208 Affected files are silcd/server.c, server_util.[ch] and
211 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
213 * Added preliminary support for signals in scheduler. The
214 signals we care about are now blocked always when the scheduler
215 is locked. This way we can synchronise the use of signal with
216 scheduler. It is guaranteed that when signal occurs the scheduler
217 is not locked, and thus new tasks can be safely added to the
220 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
221 to silc_schedule_internal_init and silc_schedule_internal_uninit.
222 Added new platform specific routines
223 silc_schedule_internal_signals_[un]block and
224 silc_schedule_internal_signal_[un]register.
226 Added new functions to SILC Schedule API:
227 silc_schedule_signal_[un]register. Each signal that application
228 is going to use should be registered to the scheduler.
230 Affected files are lib/silcutil/silcschedule.[ch],
231 lib/silcutil/*/silc*schedule.c.
233 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
235 * Check for unauthenticated client and server in the
236 silc_server_new_client and silc_server_new_server functions.
237 Affected file silcd/packet_receive.c.
239 * Added function silc_string_is_ascii to check whether given
240 string is 7-bit ASCII string. Affected files are
241 lib/silcutil/silcutil.[ch].
243 * Added function silc_id_is_valid_server_id into the
244 silcd/serverid.c and added checking for valid Server ID's in
245 silc_server_new_server. The Server ID must always be based
246 on the server's public IP address.
248 * Added logging of DISCONNECT packet message in the server.
249 Affected file silcd/server.c.
251 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
253 * Changed all library interfaces that use Global RNG to also
254 accept SilcRng as argument. Affected files are
255 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
256 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
257 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
258 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
261 * Added function silc_pkcs_generate_key to the
262 lib/silccrypt/silcpkcs.[ch] for applications so that they
263 don't need to do pkcs->pkcs->init calls anymore.
265 * Remove SilcSocketConnection from the SFTP API since it really
266 wasn't needed there. The application has the information
267 saved in its contexts anyway and the SFTP layer doesn't need
268 know about it. Affected files lib/silcsft/silcsftp.h and
269 lib/silcsftp/sftp_[server/client].c.
271 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
272 The SilcSimContext is not SilcSim.
274 * Fixed possible buffer overflows in silc_id_render in the
275 lib/silcutil/silcutil.c.
277 * On EPOC the global crypto module lists are not used at all
278 in the crypto library. Added support for using the constant
279 algorithm list on EPOC. Affected files are
280 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
283 * Fixed the handling of third parameter of KICKED notify, since
284 it was mistakenly updated to SILC Protocol 1.0 even though it
285 is to be included in 1.1. Since it is not in 1.0 it is not
286 mandatory, and this fix now handles it only if it is provided,
287 and it is not error if it is not provided. Affected file
288 lib/silcclient/client_notify.c.
290 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
292 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
293 client. Affected file irssi/src/silc/core/client_ops.c.
295 * Merged with Irssi 0.8.4 from irssi.org CVS.
297 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Check for valid socket connection in client entries before
300 sending any messages. Fixes a crash, but doesn't fix some
301 other underlaying bug that is lurking there. Affected
302 file silcd/packet_send.c.
304 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
306 * $usermode, $cumode and $cumode_space expandos shouldn't do
307 anything with non-SILC server records. Affected file
308 irssi/src/silc/core/silc-expandos.c
310 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Fixed the silc_net_check_[host/local]_by_sock to support
313 IPv6 bound sockets as well. Now they can return IPv6 addresses
314 as well. Affected file lib/silcutil/silcnet.c.
316 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
317 Affected lib/silcutil/unix/silcunixnet.c.
319 * Fixed ID rendering (at least on some platforms, not NetBSD)
320 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
322 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Added silc_hash_public_key and silc_hash_public_key_compare
325 functions to be used with SilcHashTable. They can be used to
326 hash public keys and compare public keys in hash table. Affected
327 file lib/silcutil/silcutil.[ch].
329 * Added support for specifying multiple public keys for Client
330 connection section in server configuration file. This makes it
331 possible to accept multiple public keys from same host, or to
332 make a section that accepts any incoming host, and have the
333 accepted public keys listed in the section.
335 Added functions silc_sever_[find/get]_public_key, added the
336 support for this actually to all connection sections but only
337 the Client section is currently allowed to specify multiple
340 Affected files are silcd/server.c, server_internal.h,
341 command.c, protocol.c, server_util.[ch], packet_receive.c.
343 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
345 * Merged Irssi 0.8.2 from irssi.org CVS.
347 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
349 * If silc_debug is TRUE, also output standard logging messages
350 to stderr with the debug output.
352 Made silc_log_reset_all() flushing all channels before returning.
353 Also fixed some documentation typos.
355 Affected files are lib/silcutil/silclog.[ch].
357 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Fixed the server to check correctly the amount of connections
360 from single host, by checking also the type of the connection.
361 Fixed also the comparison of number of connections and number
362 of allowed connections. Affected files are silcd/server.c,
365 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Fixed the USERS command reply to save the user's mode on the
368 channel as well. Fixed JOIN command reply to check whether a
369 client is on channel already and not join it twice. Affected
370 file lib/silcclient/command_reply.c.
372 * Added new file silc-expandos.c into irssi/silc/core/ to return
373 various stuff for various signal for the statusbar etc. updating.
374 Now Irssi SILC client prints channel user modes etc. on the
377 * The user mode (like server/router operator changes) is now shown
378 on the Irssi SILC client's statusbar. The affected files are
379 irssi/src/silc/core/client_ops.c, silc-expandos.c.
381 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
383 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
384 to SILC_SCHEDULE_[UN]LOCK macros.
386 * Added more error printing to logs in server code. Affected
387 files silcd/server.c and silcd/protocol.c.
389 * Fixed -S option parsing in Irssi SILC Client. Affected file
390 irssi/src/silc/core/silc-core.c.
392 * Added silc_buffer_alloc_size function. Affected file is
393 lib/silcutil/silcbuffer.h.
395 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
397 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
398 constants. Affected files in
399 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
402 * Changed the internal SFTP Memory FS table to const. Affected
403 file lib/silcsftp/sftp_fs_memory.c.
405 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
407 * Fixed the buffer formatting and unformatting routines to
408 check the size of 64 bits types with sizeof(). Affected
409 file is lib/silcutil/silcbuffmt.c.
411 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
413 * Removed 0.6.x backwards support.
415 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
417 * Changed all integer type names:
418 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
419 to avoid collisions with other libraries using same type names
422 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
424 * Added `prefer_ipv6' argument to the functions
425 silc_net_gethostbyname[_async]. If it is TRUE it will return
426 IPv6 address over IPv4. If FALSE IPv4 address is returned
427 even if IPv6 address was found. Affected files
428 lib/silcutil/silcnet.[ch].
430 * Added support silc_net_create_connection[_async] to fallback
431 to IPv4 address if IPv6 address could not be used (like if
432 it doesn't work on a specific system). Affected file in
433 lib/silcutil/unix/silcunixnet.c.
435 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
437 * Added silc_schedule_reinit function to do the enlarging
438 of the max tasks handling capabilities of the scheduler.
439 Affected files lib/silcutil/silcschedule.[ch].
441 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Added automatic extern "C" { ... } for C++ compilers so the
444 application does not need to define them. Affected file
445 includes/silcincludes.h.
447 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
448 old name went against naming convention. Applications now
449 include "silcclient.h" instead of "clientlibincludes.h".
450 Removed includes/clientlibincludes.h, it is redundant now.
452 * Renamed includes/version.h to silcversion.h.
454 * Added really preliminary support for OS/2 into the util
455 library. Only thread & mutex API is implemented, others
456 are still to be implemented. Created the lib/silcutil/os2/
457 directory. Created also file includes/silcos2.h.
459 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
461 * Added preliminary BeOS support into the util library.
462 Created lib/silcutil/beos/, and implemented all the needed
463 functions to support SILC on BeOS. Created also file
466 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
468 * Added proper initializations to silc's irssi code, so it's
469 now possible to load it as module. Affected files
470 irssi/src/silc/core/silc-core.c,
471 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
473 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
475 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
478 * Fixed the silcdoc document generator to correct generate
479 docs from all kinds of filenames. Affected files are
480 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
482 * ROBOdoc documented lib/silcutil/silcmemory.h.
483 Added also new function silc_memdup.
485 * Removed lib/silcutil/silcbufutil.h and moved those routines
486 to the lib/silcutil/silcbuffer.h.
488 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
490 * Added `user_count' to the SilcChannelEntry which now tells the
491 number of users on the channel. The user count is now saved
492 in normal server of global channels as well. Affected files
493 silcd/server.c, idlist.h, packet_receive.c and command.c.
495 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
496 include file utility functions.
498 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
499 instead of calling directly OS routines.
501 * Fixed NICK change printing in Irssi SILC Client. Fixed
502 KICKED notify printing in Irssi SILC Client. Affected file
503 irssi/src/silc/core/client_ops.c.
505 * Fixed a NICK change bug in client library, to not recreate the
506 client_entry->channels hash table everytime nick is changed.
507 Affected file lib/silcclient/client.c.
509 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
511 * ROBOdoc documented the lib/silcske/silcske.h, and improved
512 the SKE interface a bit.
514 * Fixed padding problem in PKCS#1. The padding was not actually
515 random since the random number generator was used incorrectly.
516 This security bug affects only when encrypting with PKCS#1, and
517 it is not currently used at all in SILC. SILC only use signing
518 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

598 * Splitted the doc/example_silcd.conf.in. Separated the crypto
599 algorithm parts and created new file silcalgs.conf, that
600 is now included from the example_silcd.conf.in.
602 * Optimized the silc_server_connect_to_router_second to take
603 the connection configuration object from the SilcServerConnection
604 object instead of finding it during the connecting phase.
605 Added the configuration object to SilcServerConnection struct.
606 Affected files silcd/server_internal.h, server.c.

630 authentication to be set at the same time.
632 Added `prefer_passphrase_auth' setting in config file which
633 can be used to set to prefer passwd auth if both passwd and
634 public key is set. If not set, public key is preferred.
635 This has effect only when being initiator (responder will try
638 Added support for authentication with passphrase and public key
639 at the same time. The passphrase is tried first always since
640 it is faster to check.
642 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
644 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

688 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
690 * Fixed the file transfer's key agreement payload to include
691 zero port also if the hostname is NULL because it could not
694 Call file transfer monitor callback now also if error occurs
695 during key agreement protocol.
697 Changed the silc_client_file_send interface to return the
698 SilcClientFileError instead of session id. The session ID
699 is returned into pointer provided as argument.

716 file lib/silcutil/silclog.c.
718 * Fixed the channel message payload decryption in the function
719 silc_channel_message_payload_decrypt to not modify the original
720 buffer before it is verified that the message decrypted
721 correctly. Otherwise, next time it is called with correct
722 channel key it won't encrypt since the payload is corrupted.
723 Affected file lib/silccore/silcchannel.c.
725 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

738 the table with foreach callback. The current entry may
739 become invalid in the callback but it was referenced after
740 the callback returned.
742 Do not allow auto rehashing of hash table during the
743 silc_hash_table_foreach operation, for same reasons as it is
744 not allowed for SilcHashTableList. Affected files are
745 lib/silcutil/silchashtable.[ch].
747 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Defined DLLAPI into silcincludes.h and silcwin32.h for

753 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
755 * Fixed private message handling. It used some old code that
756 caused the client to crash. Affecte file is
757 lib/silcclient/client_prvmsg.c.
759 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
761 * Added function silc_client_add_channel,
762 silc_client_replace_channel_id, and removed functions
763 silc_client_new_channel_id and silc_idlist_get_channel_by_id
766 * Added cross reference of the joined channels to the
767 SilcClientEntry, and changed the SilcChannelEntry's
768 users list to SilcHashTable. The affected files are
769 lib/silcclient/idlist.[ch].
771 * Fixed a bug in hash table tarversing. While the hash table
772 is traversed with SilcHashTableList the table must not be
773 rehashed. It is now guaranteed that auto rehashable tables
774 are not rehashed while tarversing the list. Also defined that
775 silc_hash_table_rehash must not be called while tarversing
776 the table. Added function silc_hash_table_list_reset that must
777 be called after the tarversing is over. The affected files are
778 lib/silcutil/silchashtable.[ch].
780 * Changed all hash table traversing to call the new
781 silc_hash_table_list_reset in server and in client library.
783 * Added function silc_client_on_channel to return the
784 SilcChannelUser entry if the specified client entry is joined
785 on the specified channel. This is exported to application as
786 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
788 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
790 * Fixed founder regaining problem with JOIN command on normal
791 server. The notify for mode change must be sent always and
792 not only if !cmd->pending. Affected file silcd/command.c.
794 * Fixed the WHOWAS command's reply sending to support the
795 lists correctly. Affected file silcd/command.c.
797 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
799 * When sending JOIN command to router for processing the
800 sender's old command identifier was not saved back to the
801 sender's command context, fixed now. The affected file is
804 * Create the key in JOIN command of the router did not return
805 the channel key, added check for this. Affected file is
808 * Fixed a channel ID update bug in JOIN command reply. Do
809 not directly upgrade the ID but call the function
810 silc_idlist_replace_channel_id if the ID was changed.
811 Affected file silcd/command_reply.c.
813 * Fixed memory leaks from command calling if it would fail.
814 Affected file silcd/command.c.

824 * Removed dotconf from lib/dotconf, not needed anymore.
826 * Removed TRQ from lib/trq, not needed anymore.
828 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
829 with server connections. Later this will be configurable
830 in config file after new config file is done. Affected file
833 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Fixed a crash in server related to channel announcements.
836 Affected file silcd/server.c.
838 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
840 * Fixed memory leaks in silc_server_create_new_channel*
841 functions. Affected file silcd/server.c.
843 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
844 which ID was changed. This way the router will send the
845 user list for the channel again, and server won't be in
846 desync in some rare circumstances. Affected file is
847 silcd/packet_receive.c.
849 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Check for NULL socket pointer in the function

861 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
863 * Added lib/silcclient/client_ops_example.h as an template
864 file for application programmers to quickly start using
865 the SilcClientOperation functions in their application.
866 Updated the lib/silcclient/README as well to tell about this
867 nice file made available.
869 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
871 * Call silc_server_remove_from_channels when removing client
872 entry when NO_SUCH_CLIENT_ID was received. Affected file
873 is silcd/command_reply.c.
875 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Added server & router operator statistics updating. Affected
878 file silcd/packet_receive.c and silcd/command.c.
880 * Fixed the SERVER_SIGNOFF notify handling on normal server
881 not to save the history information for clients. Same was
882 fixed earlier in remove_clients_by_server function, but not
883 here. Affected file silcd/packet_receive.c.
885 * Raised the default connection-retry count from 4 to 7 in
886 server. Affected file silcd/server.h.
888 * Cancel any possible reconnect timeouts when we start the
889 key exchange. Affected file silcd/server.c.
891 * Do not reconnect on connection failure when SCONNECT was
892 given. Affected files silcd/server.[ch].
894 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
896 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
898 * Fixed the NICK command to always give the unformatted
899 nickname to the one giving the NICK command. If unformatted
900 nickname is cached already it will be formatted and the
901 local entry will always get the unformatted nickname.
902 Affected file lib/silcclient/idlist.c.
904 * Fixed some double frees from client library commands.
905 Affected file is lib/silcclient/command.c.
907 * Fixed CUMODE command in server to assure that no one can
908 change founder's mode than the founder itself, there was a
909 little bug. Affected file silcd/command.c.
911 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
913 * Removed the SilcClientCommandDestructor from the client
914 libary, it is not needed anymore. Affected files are
915 lib/silcclient/silcapi.h, command[_reply].[ch],
916 client_notify, idlist.c.
918 * Fixed GETKEY command to first resolve client, and then
919 resolve the server only if the client was not found, instead
920 of resolving both at the same time. Affected file is
921 lib/silcclient/command.c.
923 * Added silc_client_start_key_exchange_cb and lookup the
924 remote hostname and IP address before starting the key
925 exchange with server. The affected file is
926 lib/silcclient/client.c.
928 * The server's public key is now saved using the IP address
929 of the server and not the servername for the filename.
930 The hostname public key filename is checked as an fall back
931 method if the IP address based filename is not found.
933 Fixed the GETKEY command to save the fetched server key
936 Print the remote server's hostname now when new key is
937 received during connection process. Affected file is
938 irssi/src/silc/core/client_ops.c.
940 * Return always our own public key to the client if it asks
941 for it with GETKEY command. Affected file silcd/command.c.
943 * Removed the use_auto_addr variable from default config
944 file since it was in wrong section. Affected file is
947 * Fixed TOPIC_CHANGE notification to not route it when it
948 was sent using silc_server_send_notify_to_channel function.
949 Affected file silcd/command.c.
951 * Fixed silc_server_send_notify_kicked to send the kicker's
952 Client ID also, it was missing. Affected files are
953 silcd/command.c, silcd/packet_send.[ch].
955 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
957 * Do not save client history information in SERVER_SIGNOFF.
958 Fixes the bug in normal server that it does not detect
959 the client becoming valid after the server becomes back
960 online. Affected file silcd/server_util.c.
962 * Added `sock_error' field into the SilcSocketConnection
963 context. When error occurs during socket operation (read
964 or write) the error is saved. Added also new function
965 silc_socket_get_error to return human readable socket error
966 message. Affected files are lib/silcutil/silcsockconn.[ch],
967 lib/silcutil/unix/silcunixsockconn.c, and
968 lib/silcutil/win32/silcwin32sockconn.c.
970 * The server now prints the socket error message in the
971 signoff for client. Affected file silcd/server.c.
973 * Fixed the `created' channel information sending from router
974 to server in JOIN command. Checks now whether the channel
975 really was created or not and set it according that.
977 Fixed the JOIN command to use the client entry's current
978 ID during the joining procedure instead of the one it sent
979 in the command (it is checked though), since it can change
980 between the packet processing and command processing, and
981 would just case unnecessary pain in the client end. Affected
982 file silcd/command.c.
984 * Fixed a channel key payload sending to use correct channel
985 ID when the server was forced to change the channel's ID by
986 router. Router sent the key payload with the old Channel ID.
987 Affected file silcd/packet_receive.c.
989 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
991 * Call silc_server_save_channel_key only if the key payload
992 was provided in the JOIN command's command reply. Affected
993 file silcd/command_reply.c.
995 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
997 * Fixed silc_mp_sizeinbase to return the value correctly with
998 MPI. Affected file lib/silcmath/mp_mpi.c.
1000 * Fixed the stop_server signal to correctly stop the scheduler
1001 and gracefully stop the server when SIGTERM or SIGINT signals
1002 are received. Affected file silcd/silcd.c.
1004 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1006 * Simple handling of TERM and HUP signals. Also added some log
1007 flushing call around. Affected file is
1010 * Fixed small bugs in silclog.c. Now buffering output will take
1011 effect after 10 seconds since startup: This will ensure that
1012 no important startup messages are lost. Also output redirection
1013 will preserve original format ([Date] [Type] message).
1014 Affected file is lib/silcutil/silclog.c.
1016 * Added two options to the config file, in the logging section:
1017 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1018 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1020 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1022 * Do not print the warning about log files not being initialized
1023 more than once to avoid excess logging. Affected file is
1024 lib/silcutil/silclog.c.
1026 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1027 the SIM copying in make install in Makefile.am.pre.
1029 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1031 * Rewritten silclog APIs. Globally interesting changes follows:
1032 silc_log_set_files() changed to silc_log_set_file().
1033 silc_log_set_callbacks() changed to silc_log_set_callback().
1034 ROBOdoc documented silclog header file.
1035 SilcLogCb now returns bool to wether inihibit the default
1036 handler or not (to keep the old behaviour return always TRUE).
1037 The new APIs should also fix the problem of the
1038 silcd_error.log file that was written in the current directory.
1041 Log files streams will remain opened after silc_log_set_file()
1042 call, means less CPU usage notably on high traffic servers.
1043 File streams are now full buffered, and flushed to the disk
1044 every 5 minutes, lesses HD activity and CPU usage.
1045 Messages can be redirected, allowing admins to configure
1046 one single logfile for all server messages.
1047 the silc_log_quick global variable to activate fast-logging.
1048 Affected files lib/silcutil/silclog.[ch]
1050 * Changed some code to conform new silclog APIs. Affected
1051 files are doc/example_silcd.conf.in, silcd/server.c
1052 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1055 * Fixed a memory leak that could occur in some situations.
1056 Affected file silcd/serverconfig.c.
1058 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1060 * Added the silc_client_del_client to remove the client from
1061 all channels as well. Affected file lib/silcclient/idlist.c.
1063 * Fixed the client library to correctly remove the client
1064 from all channels when the client entry is being destroyed.
1065 Affected file lib/silcclient/client_notify.c, command.c.
1067 * Added auto-nicking support to the client library. If the
1068 applicatio now sets client->nickname it will be sent to the
1069 server after connecting by the library. This way for example
1070 SILCNICK (or IRCNICK) environment variables will have effect
1071 and always change the nickname automatically to whatever
1072 it is wanted. Affected file lib/silcclient/client.[ch].
1074 * Renamed silc_server_command_bad_chars to the
1075 silc_server_name_bad_chars and moved it to the
1076 silcd/server_util.[ch]. Added also new function
1077 silc_server_name_modify_bad to return nickname that
1078 includes bad characters as new nickname without those
1079 bad characters. This check and modify is now used in
1080 silc_server_new_client when the username is initially set
1081 as nickname, so it must be checked to be valid nickname.
1082 Affected file silcd/packet_receive.c.
1084 * The nickname length is now taken from the packet for real
1085 and not trusted to strlen() since it clearly can return
1086 wrong length for nickname including bad characters. This
1087 also applies to channel names. Affected file silcd/command.c.
1089 * Removed the lib/silcsilm/modules directory. Modules are now
1090 compiled into the lib/silcsim. Fixed the copying of the
1091 modules to follow symbolic links in Makefile.am.pre.
1093 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1095 * Fixed silc_string_regexify list creation. Fixes bugs with
1096 BAN and INVITE commands in server. The affected file is
1097 lib/silcutil/unix/silcunixutil.c.
1099 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Removed the command destructor entirely from the server's
1102 command and command reply routines. It is not needed, and
1103 its usage was buggy and caused crashes. Affected files are
1104 silcd/command[_reply].[ch].
1106 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Cancel protocol and NULL sock->protocol if timeout
1109 occurred during protocol. Affected file silcd/server.c.
1111 * Cancel protocol timeouts always before calling the final
1112 callback, to assure that after final callback is called
1113 no other state will be called for the protocol anymore.
1114 Affected file silcd/protocol.c.
1116 * Print error log if incoming connection configuration could
1117 not be found. Affected file silcd/server.c.
1119 * Fixed JOIN command to correctly save the founder mode
1120 to the client on normal SILC server, when the channel
1121 was created by the router. Affected file silcd/command.c.
1123 * Fixed LIST command (hopefully) to send correct reply
1124 packets. Affected file silcd/command.c.
1126 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * The silc_packet_receive_process now returns FALSE if the
1129 read data was invalid packet, and TRUE if it was ok.
1131 The server now checks that if unauthenticated connection
1132 sends data and its processing fails the server will close
1133 the connection since it could be a malicious flooder.
1135 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1137 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1139 * Make sure the warning about error opening a log file is
1140 printed only once and not everytime it fails (produces
1141 too much useless log). Affected file lib/silcutil/silclog.c.
1143 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1145 * Made the silc_server_daemonise() function more readable.
1146 Affected file silcd/server.c.
1148 * Pid file is now optional, the user may comment it out from
1149 the config file. Removed define SILC_SERVER_PID_FILE, we
1150 don't need a default any longer. Affected file
1151 configure.in.pre, lib/Makefile.am.pre.
1153 * Make some use of the pid file. The server now dies at startup
1154 if it detects a valid pid file on his path. The server would
1155 die anyway in this circumstance, because of the bind() failure.
1156 Affected file silcd/silcd.c.
1158 * No longer compiling lib/dotconf.
1160 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Fixed JOIN command parsing not to crash. Affected file
1163 lib/silcclient/command.c.
1165 * Fied the NICK_CHANGE notify to add the new client entry
1166 even it is resolved. This removes an <[unknown]> nick
1167 thingy bug in the client. Affected file is
1168 lib/silcclient/client_notify.c.
1170 * Do not try to allocate 0 bytes (efence does not like it)
1171 in lib/silccore/silccomand.c when encoding payload.
1173 * Do not take IRCNICK as nickname in Irssi SILC client since
1174 it is not possible to set nickname before hand connecting
1175 the server (TODO has an entry about adding auto-nicking
1178 * Changed the silc_server_command_pending to check whether
1179 there already exists an pending entry with the specified
1180 command, command identifier and pending callback. This is
1181 to fix IDENTIFY and WHOIS related crashes that may register
1182 multiple pending commands with same identifier. Affected
1183 file silcd/command.c.
1185 * Fixed the server to reconnect to the router even if it
1186 was already reconnecting and EOF was received. This to
1187 fix a possibility that the server wouldn't ever try to
1188 auto-reconnect to the router. Affected file silcd/server.c.
1190 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Fixed the server's password authentication to use the
1193 length of the locally saved password, and not the one
1194 sent in the packet. Affected file silcd/protocol.c.
1196 * Fixed same password authentication problem in the
1197 Authentication Payload handling routines in
1198 lib/silccore/silcauth.c.
1200 * Yet another password authentication problem fixed with
1201 channel password handling in silcd/command.c.
1203 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * If first character of string in silc_parse_userfqdn is '@'
1206 then do not parse it. Affected file is
1207 lib/silcutil/silcutil.c.
1209 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1211 * Fixed minor bug in IDENTIFY command reply sending, which
1212 caused various weird problems during JOIN when it was
1213 resolving names for users. Affected file silcd/command.c.
1215 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Fixed the IDENTIFY command reply sending to chech better valid
1218 clients. It was possible to send incomplete list of replies.
1219 Affected file silcd/command.c.
1221 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * Added silc_client_command[s]_[un]register functions now to
1224 dynamically register the commands in client library. Removed
1225 the static table of commands. This allows the client library
1226 to call commands without causing the application to know about
1227 what commands library has called.
1229 Removed the INFO command reply kludge to detect when the command
1230 was called by library. Now library use its own command reply
1231 function for INFO command.
1233 Added function silc_client_command_call to call a command.
1234 Application can use it to call command, not access the structure
1237 Now all commands that are sent by the client library (not
1238 explicitly sent by application) use own command reply functions.
1240 Affected files around lib/silcclient/ and in
1241 irssi/src/silc/core/.
1243 * Fixed the WHOIS command reply sending to chech better valid
1244 clients. It was possible to send incomplete list of replies.
1246 Fixed the WHOIS and IDENTIFY to send the request to router
1247 if normal server did not do it and did not find any results.
1249 Affected file silcd/command.c.
1251 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Moved the internal data from SilcClient context into its
1254 own file, not accesible to application. Affected files
1255 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1256 and other files in client library.
1258 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Added doc/examples installation target in Makefile.am.pre.
1263 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1266 commands the found client entry will be removed from the
1267 cache, after notifying application about the error. Affected
1268 file lib/silcclient/command_reply.c.
1270 * Changed the /MSG to check for exact nickname user gave, and
1271 not let `nick' match `nick@host' if it is only one found. Now,
1272 user must type the exact nickname (like nick@host2) even if
1273 there are no more than one same nicks found. This is to avoid
1274 a possibility of sending nickname to wrong nickname since
1275 `nick' could match `nick@host'. Affected file is
1276 irssi/src/core/silc-servers.c.
1278 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Do not print "you are now server operator" or similar when
1281 giving /away command. Affected files are
1282 irssi/src/silc/core/client_ops.c, silc-servers.h.
1284 * Made the silc_server_command_pending_error_check to send
1285 the same command reply payload it received back to the
1286 original sender of the command. This way all arguments
1287 that was received by the server will be received by the
1288 client too. Affected file silcd/command.c.
1290 * Added the silc_idcache_add to return the created cache entry
1291 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1293 * Add global clients to expire if they are not on any channel.
1294 This is because normal server will never know if they signoff
1295 if they are not on any channel. The cache expiry will take
1296 case of these entries. This is done by normal servers only.
1297 The affected files are silcd/command_reply.c,
1298 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1300 * If server receives invalid ID notification for WHOIS or
1301 IDENTIFY and the ID exists in the lists, it is removed.
1302 Affected file silcd/command_reply.c.
1304 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1305 in client then client entry that it matches is searched and
1306 the nickname is printed on the screen for user. Affected
1307 file irssi/src/silc/core/client_ops.c.
1309 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * Use cache entry expire time in the LIST command reply to
1312 purge old entries from the cache after the LIST command
1313 reply has been received. This way we don't have non-existent
1314 entries in the cache for too long. Affected file is
1315 silcd/command_reply.c.
1317 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * If we are normal server, and we've not resolved client info
1320 in WHOIS or IDENTIFY from router, and it is global client,
1321 we'll check whether it is on some channel. If it is not
1322 then we cannot be sure about its validity and will resolve it
1323 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1324 file silcd/command.c.
1326 * Search channel by name (if possible) rather than by ID
1327 in IDENTIFY command's command reply. Affected file is
1328 silcd/command_reply.c.
1330 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1333 Updated specs and implemented it. Affected file silcd/command.c,
1334 silcd/packet_send.c and silcd/packet_receive.c.
1336 * Implemented the <founder auth> payload handling in the JOIN
1337 command. If provided all conditions for channel joining
1338 except requirement to provide correct passphrase can be
1339 overrided by the channel founder. Updated the protocol specs.
1340 Affected file silcd/command.c.
1342 Added support for founder auth in JOIN command in client
1343 library. Fixed the parsing of the JOIN command now to support
1344 all options as they should be. The affected file is
1345 lib/silcclient/command.c.
1347 * Optimized the WHOIS and IDENTIFY commands to send the request
1348 to router only if it includes nicknames or other names. If
1349 they include only IDs then check the local cache first before
1350 routing. Affected file is silcd/command.c.
1352 * Added channels topic announcements. Affected file is
1353 silcd/packet_receive.c and silcd/server.c.
1355 * Fixed the silc_server_send_notify_topic_set to really destine
1356 the packet to channel. Affected file silcd/packet_send.c.
1358 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1359 library. Affected file lib/silcclient/client_notify.c.
1361 * Added UMODE announcements. Affected file silcd/server.c.
1363 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1365 * Memory leak fixes in:
1367 lib/silcutil/silcsockconn.c
1368 lib/silcske/silcske.c
1369 lib/silcske/groups.c
1371 lib/silccrypt/silcpkcs.c
1372 lib/silccore/silccommand.c
1373 lib/silccore/silcidcache.c
1378 * ROBOdoc documented the lib/silcske/groups.h file and a
1379 bit changed the interface for better.
1381 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1383 * Update the client entry context in the ID cache after
1384 nick change. Affected file lib/silcclient/command.c.
1385 Fixes the CUMODE command when regaining founder privileges,
1386 and a little WHOIS problem.
1388 * Fixed silc_net_gethostbyname to correctly call the
1389 inet_ntop. Affected file lib/silcutil/silcnet.c.
1391 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1393 * Added IPv6 support checking to the configure.in.pre, added
1394 also --enable-ipv6 option to override the check. Affected
1395 file configure.in.pre.
1397 * The silc_thread_create now calls the start function
1398 directly if threads support is not compiled in. Removes
1399 ugly #ifdef's from generic code. Affected files are
1400 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1402 * Added silc_net_gethostby[name/addr]_async to asynchronously
1403 resolve. Affected files are lib/silcutil/silcnet.[ch].
1405 * Added support for rendering IPv6 based server, client and
1406 channel IDs. Affected file lib/silcutil/silcutil.c.
1408 * Added support for creating IPv6 based server IDs. Affected
1409 file is silcd/serverid.c.
1411 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1413 * Added silc_net_gethostby[addr/name] into the
1414 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1415 routines. Added silc_net_is_ip[4/6]. Affected file is
1416 lib/silcutil/unix/silcunixnet.c. All routines that take
1417 address as argument now supports both IPv4 and IPv6 addresses.
1419 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1421 * Fixed LIST command reply sending in server. Affected file
1424 * Server now sends the kicker's client ID in the KICK notify
1425 to the kicked client. Affected file silcd/command.c.
1427 * The client library now parses the kickers client ID and
1428 UI displays it. Affected files lib/silcclient/client_notify.c
1429 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1431 * Made all payload parsing function prototypes consistent.
1432 They all take now const unsigned char * and uint32 pair as
1433 the payload data instead of SilcBuffer. Changes all around
1434 the source tree. Other unsigned char* -> const unsigned char*
1435 changes around the tree as well.
1437 * Optimized SFTP client and server packet sending not to
1438 allocate new buffer for each packet but to recycle the
1439 first allocated buffer. Affected files are
1440 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1442 * Optimized the SFTP client to use SilcList instead of
1443 SilcDList for requests, because it is faster. Affected file
1444 is lib/silcsftp/sftp_client.c.
1446 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1447 into lib/silccore/silcid.[ch].
1449 Renamed silcpayload.[ch] into silcargument.[ch].
1451 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * If client entry is deleted with active key agreement
1454 session, abort the session.
1456 The silc_client_abort_key_agreement now calls the completion
1457 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1459 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1462 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Don't use __restrict in older GCC's. Affected file is
1465 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1467 * silc_net_localhost now attempts to reverse lookup the
1468 IP/hostname. Affected file lib/silcutil/silcnet.c.
1470 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1471 command. It can be used to gain founder privileges at
1472 the same time when joining the channel.
1474 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1475 kicker's client ID as well. Updated protocol specs.
1477 Defined that the server must send SILC_COMMAND_IDENTIFY
1478 command reply with error status to client who sent
1479 private message with invalid client ID.
1481 Updated the protocol specification.
1483 * Added silc_server_send_command_reply to send any
1484 command reply. Affected file silcd/packet_send.[ch].
1486 * Added silc_id_payload_encode_data to encode ID payload
1487 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1489 * The server now send IDENTIFY command reply with error
1490 status if client ID in private message is invalid. Affected
1491 file silcd/packet_receive.c.
1493 * Save the server key file with server's IP address in
1494 the filename instead of hostname. The affected file is
1495 irssi/src/silc/core/client_ops.c.
1497 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1502 * Added libtool support for compiling shared objects in
1503 lib/silcsim. Affected file configure.in.pre and
1504 lib/silcsim/Makefile.am. Original patch by cras.
1506 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Pid file configuration, and server's config file fixes
1509 patch by toma. Updated CREDITS file.
1511 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * Fixed silc_client_channel_message to not try to decrypt
1514 the message twice if it resolved the destination client
1515 information. This could cause of dropping one channel
1516 message. Affected file lib/silcclient/client_channel.c.
1518 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1521 lib/silcclient/client.c. This function is used when the SILC
1522 Client is run under some other scheduler, or event loop or
1523 main loop. On GUI applications, for example this may be
1524 desired to used to run the client under the GUI application's
1525 main loop. Typically the GUI application would register an
1526 idle task that calls this function multiple times in a second
1527 to quickly process the SILC specific data.
1529 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1531 * Fixed silc_server_drop() for dropping the supplementary
1532 groups as well, this could cause a security hole on some
1535 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1540 * Write PID file after dropping privileges. Added -F option
1541 to run server on foreground. A patch by debolaz.
1542 Affected files silcd/server.c, silcd/silcd.c.
1544 * Fixed MOTD to return the MOTD file server name. Affected
1545 file silcd/command.c.
1547 * Added INFO command reply handling to the Irssi SILC Client.
1548 Affected file irssi/src/silc/core/client_ops.c.
1550 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Fixed the silc_idcache_list_* routines to really support
1553 the dynamic list. Fixes a crash. Affected file is
1554 lib/silccore/silcidcache.c.
1556 * Fixed the LIST command reply to really call LIST command's
1557 pending callbacks. Affected file silcd/command_reply.c.
1559 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1561 * Update conn->local_entry->nickname after giving NICK
1562 command. Affected file lib/silcclient/command.c.
1564 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1566 * Added the [pid] option to the silcd configuration file
1568 Affected files: serverconfig.[ch] and silcd.c
1570 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Save fingerprint in WHOIS command reply in server.
1573 Affected file silcd/command_reply.c.
1575 * Fixed NICK commands pending callback registration.
1576 Affected file lib/silcclient/command.c.
1578 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Use ++server->cmd_ident when sending commands in server,
1581 instead of random number. Affected file silcd/command.c.
1583 * Fixed GETKEY command reply to call actually GETKEY pending
1584 command callbacks. Affected file silcd/command_reply.c.
1586 * A bit stricter check for nicknames. Check for same nickname
1587 in NICK command also. Affected file silcd/command.c.
1589 * Do not call INFO command everytime client ID changes, only
1590 during first connecting. Affected file lib/silcclient/client.c.
1592 * Set the new nickname only after successful command reply for
1593 NICK command is returned by server. Affected file
1594 lib/silcclient/command.c.
1596 * Remove nicknames from nicklist during server_signoff notify.
1597 Should fix /NAMES bit more. The affected file is
1598 irssi/src/silc/core/silc-channels.c.
1600 * Added `fingerprint' field to the SilcIDListData in the
1601 silcd/idlist.h to hold the fingerprint of the client's
1604 Send the fingerprint of the client's public key in WHOIS
1607 Affected files silcd/command.c, and silcd/idlist.[ch].
1609 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1610 create fingerprint from given data.
1612 * Show the fingerprint of the client's public key in WHOIS.
1613 Affected files irssi/src/module-formats.[ch] and
1614 irssi/src/silc/core/client_ops.c.
1616 * Format the multiple same nicknames also during JOIN and
1617 NICK_CHANGE notifys. Affected file is
1618 lib/silcclient/client_notify.c.
1620 * Do not print error on screen for invalid private message
1621 payload since it can come if someone is sending private
1622 messages with wrong key. Affected file
1623 lib/silccore/silcprivate.c.
1625 * Fixed multiple concurrent /PING crash. Affected file
1626 lib/silcclient/command.c.
1628 * Changed the wrong ID encoding. All IP addresses must be
1629 in MSB first order in encoded format. They were encoded
1630 wrong and was in LSB format. Affected files are
1631 silcd/serverid.c, lib/silcutil/silcutil.c.
1633 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1635 * Call the `connect' client operation through the scheduler
1636 in case of error. Affected file lib/silcclient/client.c.
1638 * Call the `failure' client operation even if the error
1639 occurred locally during a protocol. Affected file is
1640 lib/silcclient/protocol.c.
1642 * Added support of sending LIST command to router from normal
1643 server. This way normal server can get list of all channels
1644 in the network too. Fixed the channel list sending in the
1645 server too. Affected files are silcd/command.c, and
1646 silcd/command_reply.[ch].
1648 * Added silc_server_update_channels_by_server and
1649 silc_server_remove_channels_by_server. They are used during
1650 disconnection of primary router and in backup router protocol.
1651 Affected file silcd/server_util.[ch], silcd/server.c and
1652 silcd/server_backup.c.
1654 * Fixed channel adding to global list in IDENTIFY command
1655 reply in server. Affected file silcd/command_reply.c.
1657 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * If the incoming packet type is REKEY or REKEY_DONE process
1660 that packet always synchronously. Fixes yet another MAC
1661 failed error on slow (dialup) connections. Affected file
1662 lib/silcclient/client.c and silcd/server.c.
1664 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1666 * Call check_version SKE callback for initiator too. Affected
1667 file lib/silcske/silcske.c.
1669 * Implemented fix for security hole found in the SKE that was
1670 fixed in the specification few days back; the initiator's
1671 public key is now added to the HASH value computation.
1672 Added backwards support for the old way of doing it too, for
1673 old clients and old servers. Affected file is
1674 lib/silcske/silcske.c.
1676 * Enabled mutual authentication by default in SKE. If initiator
1677 is not providing mutual authentication the responder will
1678 force it. This will provide the proof of posession of the
1679 private key for responder. The affected files are
1680 lib/silcclient/protocol.c and silcd/protocol.c.
1682 * Do not cache anymore the server's public key during SKE.
1683 We do mutual authentication so the proof of posession of
1684 private key is done, and if the server is authenticated in
1685 conn auth protocol with public key we must have the public
1686 key already. Affected file silcd/protocol.c.
1688 * Added new global debug variable: silc_debug_hexdump. If
1689 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1690 file lib/silcutil/silclog.[ch].
1692 * Fixed compilation warning due to char * -> const char *.
1693 Affected files lib/silcutil/silcnet.h, and
1694 lib/silccore/silcauth.[ch].
1696 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Fixed CMODE command when new channel key was created. If
1699 the creation failed the old key was removed. Next time giving
1700 same command would crash the server since the old key was
1701 freed already. Affected file silcd/command.c.
1703 * Fixed the silc_server_announce_get_channels to not crash
1704 on reconnect. Affected file silcd/server.c.
1706 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Added silc_log_set_debug_string function to set a regex
1709 string to match for debug output. Only the function names,
1710 or filenames matching the given debug string is actually
1711 printed. This way it is possible to filter out those debug
1712 strings that user is not interested in.
1714 Fixed a bug in silc_string_regexify.
1716 Affected files lib/silcutil/silclog.[ch], and
1717 lib/silcutil/unix/silcunixutil.c.
1719 * Changed the -d options in both server and Irssi SILC client
1720 to take the debug string as argument. Affected files
1721 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1723 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Added silc_hash_babbleprint to create a Bubble Babble
1726 Encoded fingerprint. The encoding is developed by Antti
1727 Huima (draft-huima-babble-01.txt), and it creates human
1728 readable strings out of binary data. Affected file
1729 lib/silccrypt/silchash.[ch].
1731 * Print the babble print now in addition of fingerprint as well
1732 in Irssi SILC client. Affected files are
1733 irssi/src/fe-common/silc/module-formats.[ch],
1734 irssi/src/fe-common/silc/core/client_ops.c.
1736 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Fixed a security problem found in SKE. The initiator's
1739 public key too is now added to the HASH hash value creation
1740 which is signed by the responder to create the SIGN value.
1741 This will prevent anyone in the middle to lie to the responder
1742 about the initiator's public key. If this is done now, the
1743 man in the middle will get caught. Updated the protocol
1746 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Better installation directory handling. Configure module
1749 paths and other paths automatically to example_silc* files
1750 in doc/. A patch by toma.
1752 * Fixed compiler warning from MPI library, and from SILC RNG.
1755 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1756 It can be configured with ./configure. A patch by toma.
1758 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Find correct make to use in prepare-clean. A patch by
1761 toma. Affected file prepare-clean.
1763 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1765 * Added irssi variables use_auto_addr, auto_bind_ip,
1766 auto_bind_port and auto_public_ip.
1768 * Changed the interface for silc_client_send_key_agreement
1769 in lib/silcclient/silcapi.h
1773 irssi/src/silc/core/silc-core.c
1775 lib/silcclient/silcapi.h
1776 irssi/src/silc/core/silc-channels.c
1777 lib/silcclient/client_keyagr.c
1780 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Added silc_pkcs_public_key_compare to compare two
1783 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1785 * Check that the client who set the founder mode on the
1786 channel is the same client that is giving the founder
1787 mode to itself. It is done by comparing the saved public
1788 key (it is saved even in the authentication is passphrase).
1789 Affected file silcd/command.c.
1791 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Do not process packet for disconnected socket connection.
1794 Affected file lib/silccore/silcpacket.c.
1796 * Process the DISCONNECT packet through scheduler in the
1797 client library. Affected file lib/silcclient/client.c.
1799 * Fixed the silc_client_packet_parse to not to increase
1800 the packet sequence number if the conn->sock and the
1801 current socket connection is not same. This can happen
1802 for example during key agreement when the conn includes
1803 multiple socket connections (listeners). Affected file
1804 lib/silcclient/client.c.
1806 * The sender of the file transfer request now provides also
1807 the pointer (listener) for the key exchange protocol. If
1808 the listener cannot be created then it sends empty key
1809 agreement and lets the receiver provide the listener.
1811 Added `local_ip' and `local_port' arguments to the
1812 silc_client_file_send. If they are provided they are used,
1813 if not then it will attempt to find local IP address, if
1814 not found or bind fails then the remote client will provide
1817 Affected files are lib/silcclient/client_ftp.c and
1818 lib/silcclient/silcapi.h.
1820 * Extended the FILE SEND command to support defining the
1821 local IP and port for key exchange listener. They are
1822 optional. Affected file irssi/src/silc/core/silc-servers.c.
1824 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Defined to WHOIS command reply the sending of fingerprint
1827 of the client's public key (if the proof of posession of the
1828 corresponding private key is verified by the server).
1829 Updated to the protocol specification.
1831 * Added support of receiving the client's public key's
1832 fingerprint in command reply in client library. Affected
1833 file is lib/silcclient/command_reply.c, and
1834 lib/silcclient/idlist.[ch].
1836 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Do not send over 128 chars long nickname to the server
1839 in NICK command. Affected file lib/silcclient/command.c.
1841 * Do not send over 256 chars long channel names to the server
1842 in JOIN command. Affected file lib/silcclient/command.c.
1844 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Assure that silc_server_close_connection cannot be called
1847 twice for same socket context. Affected file is
1850 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Send error message to application if opening file for
1853 writing during file transfer fails. Affected file is
1854 lib/silcclient/client_ftp.c.
1856 Remove all file transfer sessions for a client that we're
1857 removing from ID cache.
1859 Affected file is lib/silcclient/client_ftp.c.
1861 * Fixed silc_net_addr2bin to return correct address. Affected
1862 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1864 * Fixed file transfer session removing on signoff notify.
1865 Affected file irssi/src/silc/core/silc-servers.c.
1867 * Added the SilcClientFileError to be returned in the monitor
1868 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1869 Affected file lib/silcclient/silcapi.h.
1871 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Fixed a crash in silc_client_ftp_free_sessions and
1874 silc_client_ftp_session_free_client. Affected file
1875 lib/silcclient/client_ftp.c.
1877 * Added `disabled' field in the SilcChannelEntry in the server
1878 to indicate if the server entry is disabled. Affected file
1879 silcd/idlist.h, silcd/command[_reply].c.
1881 * SILC server adds now /var/run/silcd.pid everytime it is
1882 started. Affected file silcd/silcd.c.
1884 * Added silc_server_packet_send_clients to send a packet to
1885 the provided table of client entries. Affected file

1888 * Fixed a crash in client resolving in client_prvmsg.c in
1889 client library. Affected file lib/silcclient/client_prvmsg.c.
1891 * Do not actually remove the client directly from ID cache
1892 during SERVER_SIGNOFF, but invalidate it. This way we
1893 preserve the WHOWAS info for the client. Affected file
1894 silcd/server_util.c.
1896 * Fixed SERVER_SIGNOFF notify handling in the server. The
1897 server is now able to process incoming SERVER_SIGNOFF notify
1898 for a server that it doesn't even know about. It will remove
1899 the clients provided in the notify. Affected file
1900 silcd/packet_receive.c.
1902 * Check for partial packet in data queue after every packet that
1903 was found from the queue. Return and wait for more data if
1904 there is partial data in queue. Affected file is
1905 lib/silccore/silcpacket.c.
1907 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Added SilcClietFileError enum to indicate error in
1910 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1911 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1912 Affected files lib/silcclient/silcapi.h and
1913 lib/silcclient/client_ftp.c.
1915 * Check that newsize in silc_buffer_realloc is larger than
1916 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1918 * Added better monitor of file transfers. It now monitors
1919 key agreement protocol during the file transfer too. Added
1920 error reporting too. Affected files
1921 irssi/src/silc/core/silc-servers.c,
1922 irssi/src/fe-common/silc/module-formats.[ch].
1924 * Wrote a help file for FILE command.
1926 * Added silc_rng_global_get_byte_fast to get not-so-secure
1927 random data as fast as possible. Random data is read from
1928 /dev/urandom if available and from the SILC RNG if not
1929 available. It is used in padding generation. Affected file
1930 lib/silccrypt/silcrng.[ch].
1932 * All packets in client library are now processed synchronously.
1933 Optimized packet processing a lot. Affected file
1934 lib/silcclient/client.c.
1936 * All server connection packets are processing synchronously
1937 now in server, to optimize packet processing. Affected file
1940 * Include files are installed now only in Toolkit distribution
1941 if make install is given. Affected files: all Makefile.am's.
1943 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1945 * Assure that silc_client_notify_by_server_resolve does not
1946 resolve the client information multiple times. If it cannot
1947 be found by the first it cannot be found at all. Affected
1948 file lib/silcclient/client_notify.c.
1950 * Fixed WHOWAS command reply calling. Affected file
1951 lib/silcclient/command_reply.c.
1953 * Removed all references to silc_idlist_get_client from the
1954 Irssi SILC client since that call is internal call used by
1955 the library. The Irssi SILC client will use now client
1956 retrieval functions found in silcapi.h.
1958 * Fixed a bug in resolving nickname info before sending
1959 private message. It used freed memory. Affected file
1960 irssi/src/silc/core/silc-servers.c.
1962 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Assure my_channels statistics cannot go negative in server.
1965 Affected files silcd/server.c, silcd/server_util.c.
1967 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1971 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Win32 Toolkit changes. Affected files

1975 win32/libsilcclient/libsilc.def,
1976 lib/silcutil/silcutil.c, and
1977 lib/sftp/sftp_fs_memory.c.
1979 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Added silc_net_localip to return local host's IP address.
1982 Affected file lib/silcutil/silcnet.[ch].
1984 * If key exchange or rekey protocol is active for a connection
1985 parse all packets syncronously since there might be packets
1986 in packet queue that we are not able to process without first
1987 processing packets before them. Affected file silcd/server,
1988 lib/silcclient/client.c.
1990 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1991 whether library should continue processing the packet.
1992 Affected file lib/silccore/silcpacket.h.
1994 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1995 SilcSFTPMonitorData to SFTP server to monitor various
1996 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1997 lib/silcsftp/sftp_server.c.
1999 * Added silc_file_size to return file size. Affected file
2000 lib/silcutil/silcutil.[ch].
2002 * Implemented the file transfer support for the client library.
2003 Added preliminary support for simple client to client one-file
2004 transmission. Affected file lib/silcclient/client_ftp.c,
2005 lib/silccilent/client.[ch].
2007 * Added new local command FILE to the Irssi SILC Client.
2008 It is used to perform the file transfer. It has subcommands
2009 SEND, RECEIVE, SHOW and CLOSE. Affected files
2010 irssi/src/silc/core/client_ops.c,
2011 irssi/src/silc/core/silc-server.[ch].

2022 silc_file_open and silc_file_close. Affected files
2023 lib/silcutil/silcutil.[ch].
2025 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Resolve the client info when received private message or
2028 channel message for a client which nickname we don't know.
2029 Affected files lib/silcclient/client_prvmsg.c and
2030 lib/silcclient/client_channel.c.
2032 * Do not crash in /KEY if client is not connected. Affected
2033 file irssi/src/silc/core/silc-channels.c.
2035 * Added SilcClientStatus field to the SilcClientEntry in the
2036 lib/silcclient/idlist.h.
2038 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2039 is incomplete and is being resolved, it won't be resolved
2042 Make sure also that USERS command reply does not resolve
2043 twice information. Affected file is
2044 lib/silcclient/command_reply.c.
2046 Make sure that silc_client_get_clients_by_list does not
2047 resolve twice same information.
2049 * Check for valid client->id in the silc_server_free_client_data.
2050 Affected file silcd/server.c.
2052 * Fixed /GETKEY nick@server not to crash if the server entry
2053 is not found. Affected file lib/silcclient/command.c.
2055 * Fixed the silc_server_check_cmode_rights to check the
2056 requested modes correctly. Affected file silcd/command.c.
2058 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Better checks for non-printable chars in nick added.
2061 Affected file silcd/command.c.
2063 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Call the silc_server_udpate_servers_by_server in the
2066 primary router that comes back online in the backup resuming
2067 protocol. Otherwise it routes packets wrong. Affected file
2068 silcd/server_util.[ch], silcd/server_backup.c.
2070 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2073 lib/silcutil/silcbuffmt.[ch].
2075 * Redefined the SILC packet header to include the padding
2076 length. Affected file lib/silccore/silcpacket.[ch].
2078 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2079 length for maximum padding up to 128 bytes). Affected
2080 file lib/silccore/silcpacket.h.
2082 * Removed all backwards support for old 0.5.x MAC thingies.
2083 The SILC packet header change makes it impossible to be
2084 backwards compatible.
2086 * Send the ENDING packet with timeout in the backup resuming
2087 protocol. This is to assure that all routers has connected
2088 to the primary router. Affected file silcd/server_backup.c.
2090 * Changed the RNG to take the first IV from random data. It
2091 used to take it from zero actually. Changed the RNG also
2092 to use /dev/urandom during session. /dev/random is used
2093 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2095 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2097 * Changed the SILC packet header to have the first two bytes
2098 (the packet length) encrypted. Affected files aroung the
2099 code tree, lib/silccore/silcpacket.[ch]. Removed the
2100 SilcPacketCheckDecrypt callback. It is not needed anymore
2101 since the silc_packet_receive_process will determine now
2102 whether the packet is normal or special.
2104 * Implemented the unidirectional MAC keys. Affected files
2105 lib/silcske/silcske.c, silcd/protocol.c and
2106 lib/silcclient/protocol.c.
2108 * Implemented the packet sequence number to the MAC computation.
2109 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2110 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2111 lib/silcclient/protocol.c.
2113 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2115 * Allow backup router to announce servers. All servers
2116 announced by backup router are added to the global list
2117 automatically. Update hte server's socket to our primary
2118 router also when backup router announces a server.
2119 Affected file silcd/packet_receive.c.
2121 * Do not update the client->router in the function
2122 silc_server_udpate_clients_by_server if the client is on
2123 global list. We might fail to find any specific server
2124 for locally connected clients and local cell clients. They
2125 should still use the `from' and not `to' as client->router.
2126 This fixes backup router resuming protocol. Affected file
2127 silcd/server_util.c.
2129 * Decrease channel statistics count only if the channel
2130 deletion worked. Affected files are silcd/server.c and
2131 silcd/server_util.c.
2133 * Added silc_server_update_servers_by_server to update origin
2134 of all server entries. Used during backup router protocol.
2135 Affected files silcd/server_util.[ch], silcd/server.c. and
2136 silcd/backup_router.c.
2138 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2139 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2140 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2141 lib/silccrypt/silchmac.c.
2143 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Assure that router cannot reroute the same channel message
2146 to the sender. Affected file silcd/packet_receive.c.
2148 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Made better checks that the channel message is not sent
2151 to the router it came from. Affected file is
2152 silcd/packet_send.c. Fixed memory leak too.
2154 * Announce informations for incoming router connection, but
2155 only after checking if it is replaced by backup router.
2156 Affected file silcd/packet_receive.c.
2158 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Fixed the backup resuming protocol to work in multiple
2161 router environment. Affected file silcd/server_backup.c.
2163 * Route packet only to one router in the function
2164 silc_server_packet_send_to_channel. Affected file is
2165 silcd/packet_send.c.
2167 * Fixed silc_server_send_notify_dest to set the broadcast
2168 flag. Fixed the silc_server_send_notify_topic to actually
2169 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2170 Affected file silcd/packet_send.c.
2172 * Changed the SFTP Filesystem interface. Changed the
2173 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2174 the filesystem operation function. The SilcSFTPFilesystem
2175 is now a context that is allocated by all filesystem allocation
2176 functions and it already includes the operations structure
2177 and filesystem specific context. It is given as argument
2178 now to the silc_sftp_server_start. This made the interface
2179 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2180 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2182 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Changed the backup router adding and getting interfaces
2185 in the server. The router that will be replaced by the
2186 specified backup router is now sent as argument. Affected
2187 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2190 * Added silc_net_addr2bin_ne to return the binary form of
2191 the IP address in network byte order. Affected files
2192 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2194 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Check for existing server ID in silc_server_new_server
2197 and in silc_server_connect_to_router_final and remove the
2198 old entry if it exists. Affected file silcd/packet_receive.c,
2201 * Send the channel message always to only one router, either
2202 in upstream or downstream. Affected file is
2203 silcd/packet_send.c.
2205 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Wrote the definition of the backup resuming protocol to the
2208 protocol specification.
2210 * Removed one redundant channel key generation from normal
2211 server during joining procedure. Removed one redundant
2212 channel key sending from server to router during joining
2213 procedure. Affected file silcd/command.c.
2215 * Made minor bugfixes to the backup router resuming protocol.
2216 Affected file silcd/server_backup.c, server.c.
2218 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Added --disable-asm configuration option. Affected files
2221 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2224 * Implemented the backup resuming protocol that is used to
2225 resume the primary router position in the cell after the
2226 primary router comes back online. Affected files
2227 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2228 and silcd/server_util.[ch].
2230 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Sleep two (2) seconds after sending QUIT command to server.
2233 Affected file lib/silcclient/command.c.
2235 * Assure that if outgoing data buffer is pending do not force
2236 send any data. Affected file silcd/packet_send.c.
2238 * Assure that if outgoing data buffer is pending do not force
2239 send any data. Affected file lib/silcclient/client.c.
2241 * Implemented the backup router support when the primary router
2242 goes down. The servers and routers can now use the backup
2243 router as new primary router without loosing connectivity.
2245 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2248 in the server to indicate disabled entry. All data read
2249 from the connection will be ignored and no data is sent
2250 for entry that is disabled. Affected files are
2251 silcd/idlist.h, silcd/server.c.
2253 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Created SFTP client and server test programs in the
2256 lib/silcsftp/tests directory.
2258 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Implemented memory filesystem (virtual filesystem) for
2261 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2264 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Implemented the SFTP (SSH File Transfer Protocol) to the
2267 lib/silcsftp. It includes SFTP client and SFTP server
2270 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Moved lib/silccore/silcprotocol.[ch] to the
2273 lib/silcutil library.
2275 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2276 take variable argument list pointer as argument. Affected
2277 file lib/silcutil/silcbuffmt.[ch].
2279 * Added silc_buffer_set function that is used to set data
2280 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2281 Affected file lib/silcutil/silcbuffer.h.
2283 * Changed various routines in the core library to use the new
2284 silc_buffer_set instead of allocating new buffer only for
2287 * Added 64-bit value formatting and unformatting support to the
2288 silc_buffer_[un]format routines. Affected file is
2289 lib/silcutil/silcbuffmt.[ch].
2291 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2292 to includes/bitmove.h.
2294 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Fixed channel user mode saving in client library. Affected
2297 file lib/silcclient/command[_reply].c.
2299 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Defined the file transfer to the SILC Protocol. Added
2302 new packet type SILC_PACKET_FTP and defined File Transfer
2303 Payload. The mandatory file transfer protocol is SFTP
2304 (SSH File Transfer Protocol). Affected file in addition
2305 of the internet draft is lib/silccore/silcpacket.h.
2307 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2308 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2309 is used as part of backup router protocol when the primary
2310 router of the cell is back online and wishes to resume
2311 the position as primary router.
2313 * Redefined the MAC generation keys in the protocol. The
2314 same key is not used anymore in both direction. Both
2315 direction will now use different keys for sending and
2316 receiving. This fixes a potential security flaw. This
2317 change causes incompatibilities in the protocol.
2319 * Redefined also the MAC computation from the packet.
2320 An packet sequence number is now added to the MAC
2321 computation. This prevents possible replay attacks against
2322 the protocol. This change too causes incompatibilities
2325 Added `sequence' field to the SilcPacketContext to hold
2326 the current sequence number for the packet.
2328 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Added `created' field to the SilcIDListData in the file
2331 silcd/idlist.h to indicate the time when the entry was
2334 * Added `created' field to the SilcChannelEntry too. Affected
2335 file silcd/idlist.h.
2337 * Added `creation_time' aguments to all the announcement functions
2338 in the server. If it is provided then only the entries that
2339 was created after the provided time frame are actually
2340 announced. Affected file silcd/server.[ch].
2342 * The protocol says that the Channel ID's IP address must be
2343 based on the router's IP address. Added check for this in
2344 the silc_server_new_channel when processing incoming New Channel
2345 Payload. Affected file silcd/packet_receive.c.
2347 * Print out the correct version with --version in SILC client.
2348 Affected file irssi/src/silc/core/silc-core.c.
2350 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2352 * Fixed WHOWAS command to check for completnes of the client
2353 entry always, not just when the command is coming from client.
2354 Affected file silcd/command.c.
2356 * Added new function silc_server_packet_queue_purge to purge the
2357 outgoing data queue to the network. After the function returns
2358 it is guaranteed that the outgoing packet queue is empty.
2359 Affected file silcd/packet_send.[ch].
2361 * Purge the outgoing packet queue in the rekey protocol's final
2362 callback to assure that all rekey packets go to the network
2363 before quitting the protocol. Affected file silcd/server.c.
2365 * Added silc_client_packet_queue_parse as similar function as
2366 in server to the client library. The affected file is
2367 lib/silcclient/client.c.
2369 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Splitted silcd/server.c and created silcd/server_util.[ch]
2372 for utility functions.
2374 * Added new socket flag SILC_SF_DISABLED to indicate that the
2375 connection is open but nothing can be sent to or received from
2376 the connection. Affected file lib/silcutil/silsockconn.[ch].
2377 The checking for disabled socket is checked in the low level
2378 silc_socket_write and silc_socket_read functions.
2380 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Allow only nicknames and channel names that fits into the
2383 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2385 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * When processing JOIN command reply in server check that if
2388 the channel exists in our global list we'll move it the local
2389 list. Affected file silcd/command_reply.c.
2391 * Fixed the check whether client is joined on the channel already
2392 in JOIN command. Affected file lib/silcclient/command.c.
2394 * Fixed the JOIN command reply to check whether the channel
2395 already exists. Affected file lib/silcclient/command_reply.c.
2397 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Added silc_ske_status_string to map the SKE error numbers
2400 to readable strings. The affected files are
2401 lib/silcske/silcske[_status].[ch].
2403 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Do not show the private channels on the WHOIS channel list
2406 as it is not allowed by the protocol. The affected file is
2409 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Assure that the packet length digged from the actual packet
2412 is something sensible in the silc_packet_decrypt_rest_special
2413 in lib/silccrypt/silcpacket.c.
2415 * Free and NULL the allocated pointer in silc_hmac_alloc if
2416 the HMAC allocation fails. The affected file is
2417 lib/silccrypt/silchmac.c.
2419 * Print the selected security properties to the log files in
2420 the server. Affected file silcd/protocol.c.
2422 * Add SKE's reference counter even if calling the completion
2423 callback manually. Otherwise it goes negative, although it
2424 does not cause any problems. The affected file is
2425 lib/silcske/silcske.c.
2427 * Remove the client entry with short timeout after giving the
2428 KILL command. Affected file lib/silcclient/command.c.
2430 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2431 case all found clients are already disconnected (WHOWAS would
2432 found them) in the server. Affected file silcd/command.c.
2434 * Update the last_receive (time of last data received) to be
2435 updated only when received private or channel message so that
2436 the idle time showed in WHOIS makes more sense.
2438 * Added boolean field `valid' in to the SilcClientEntry in the
2439 client library to indicate whether the entry is valid or not.
2440 This fixes the nickname change bug on channel when changing
2441 the nickname to be same than the old (like nick to Nick) the
2442 nickname formatter doesn't set the new nick anymore to Nick@host.
2443 Affected file lib/silcclient/idlist.[ch].
2445 * Now actually fixed the nickname changing on disconnection.
2446 Added new function silc_change_nick to the Irssi SILC Client.
2447 Affected file irssi/src/silc/core/client_ops.c,
2448 irssi/src/silc/core/silc-nicklist.[ch].
2450 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Check that the public key exists in the GETKEY command before
2453 trying to encode it. Affected file silcd/command.c.
2455 * Print some notifications on received public keys with GETKEY
2456 command in the Irssi SILC Client. Affected files are
2457 irssi/src/fe-common/silc/module-formats.[ch],
2458 irssi/src/silc/core/client_ops.c.
2460 * Use IDENTIFY command to resolve the server information in the
2461 GETKEY command instead of INFO command. Affected file
2462 lib/silcclient/command.c.
2464 * All command reply functions in the client library now calls
2465 the pending command reply callbacks even if an error has
2466 occurred. The server has done this a long time and now it was
2467 time to move the client library to this as well. Now all
2468 errors can be delivered back to the pending command reply
2469 callbacks if necessary. Affected files are
2470 lib/silcclient/command[_reply].[ch].
2472 * Change the nickname on disconnection back to the username
2473 because in reconnect the server will enforce it to it anyway.
2474 Affected file irssi/src/silc/core/silc-servers.c.
2476 * Fixed a config file parsing bug in the Irssi SILC client.
2477 Affected file irssi/src/silc/core/clientconfig.c.
2479 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2481 * When printing the channel mode on JOIN, verify that the
2482 channel key and channel's HMAC are valid. Affected file
2483 irssi/src/silc/core/client_ops.c.
2485 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2488 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2489 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2491 * Removed channel key rekey task deleting from the function
2492 silc_server_save_channel_key. Affected file silcd/server.c.
2493 Added explicit timeout task context instead that is used to
2494 delete the task if we are registering a new task before the
2495 new task has elapsed.
2497 * When channel key rekey occurs the client library now saves
2498 the old channel key for a short period of time (10 seconds) and
2499 is able to use it in case some is still sending channel
2500 messages encrypted with the old key after the rekey. Affected
2501 file lib/silcclient/[idlist.h|client_channel.c].
2503 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Added check to the silc_server_new_id_real to not accept
2506 new ID if it is the sender's own ID. Affected file is
2507 silcd/packet_receive.c.
2509 * Assure that we do not announce ourself or the one we've
2510 sending our announcements when we're router and are announcing
2511 servers to our primary router. Affected file silcd/server.c.
2513 * Fixed silc_server_command_identify_check_client to assemble
2514 correct WHOIS packet. It send corrupted WHOIS packet and
2515 caused problem with router to router connections. Affected
2516 file silcd/command.c.
2518 Fixed also silc_server_command_whois_check the same way
2519 as for the IDENTIFY command.
2521 * Added new SilcIDListStatus to the server in the SilcIDListData
2522 structure. The status now includes the current status of
2523 the entry (like registered, resolved etc.). Affected file
2524 silcd/idlist.[ch]. Defined a bunch of different status types
2525 as well. This replaced the old boolean registered field as well.
2527 Added resolve_cmd_ident field to the SilcClientEntry structure
2528 too so that if the entry is for example being resolved so
2529 another command may attach to the same pending command reply
2530 without requiring to resolve the same entry again. This concept
2531 should optimize the WHOIS and the IDENTIFY resolving under
2532 heavy load by taking away unnecessary resolving for entries
2533 that are being resolved already.
2535 Added support for adding multiple pending commands for one
2536 command idenfier. Affected file silcd/command[_reply].[ch].
2538 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2539 before deleting the data. Otherwise the hash table will have
2540 freed data in comparison functions. Affected file is
2541 silcd/command_reply.c.
2543 * Fixed silc_idlist_replace_client_id to add the new entry to
2544 the cache with NULL nickname. Otherwise there will be invalid
2545 memory as the nickname after the nickname is freed. Affected
2546 file silcd/packet_receive.c.
2548 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2549 saved into wrong slots because the previous number of entries
2550 was not taken into account. Affected file silcd/idlist.c.
2551 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2553 * If we are router and we receive JOIN notify to a channel that
2554 does not have any users then notified client is marked as the
2555 channel founder, as it is it. The affected file is
2556 silcd/packet_receive.c
2558 * Added to the extended hash table API's table_del_*ext functions
2559 the destructor as argument too, so that the caller can decide
2560 which destructor to use or whether to use destructor at all.
2561 Affected file lib/silcutil/silchashtable.[ch].
2563 * Fixed ID Cache purging. It actually deleted the entries from
2564 the hash table after the data was freed. The hash table ended
2565 up comparing freed memory. The affected file is
2566 lib/silccore/silcidcache.c.
2568 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Fixed Irssi SILC client's KILL command's HELP syntax.
2572 * The USERS command now resolves the detailed user information
2573 if the userinfo field is missing. Affected file is
2574 lib/silcclient/command_reply.c.
2576 * Do not print error in silc_file_read if the read file does
2577 not exist. Just silently return NULL. Affected file is
2578 lib/silcutil/silcutil.c.
2580 * Fixed the silc_log_output to not wine about NULL filename
2581 and to not create some bogus " " filename. Affected file is
2582 lib/silcutil/silclog.c.
2584 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Fixed various printing bugs on the user interface in the
2587 Irssi SILC Client. Minor changes that were forgotten from
2590 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Fixed the configure.in.pre and the compilation and distribution
2593 environment to support the new autoconf 2.52. That version is
2594 now required to compile the CVS trunk.
2596 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2599 to generally parse user@fqdn format strings. Affected file
2600 lib/silcutil/silcutil.c.
2602 * Added nickname_format and nickname_force_format fields to the
2603 SilcClientParams structure. The first one defines the format
2604 for the nicknames that the library will enforce if the receives
2605 multiple same nicknames. The second one is boolean value and
2606 can be used to force the library to always enforce the format
2607 to the nicknames regardles whether there are multiple nicknames
2608 or not. This configurable formatting was employed to flexibly
2609 support accessing multiple nicknames from the user interface.
2610 The userinterface can now set the nicknames to what ever format
2611 they prefer. Affected file lib/silcclient/silcapi.h.
2613 Added function silc_client_nickname_format to the file
2614 lib/silcclient/idlist.c. It performs the nickname formatting.
2616 Added new field `hostname´ to the SilcClientEntry context.
2617 It holds the hostname of the client. Affected file is
2618 lib/silcclient/idlist.h.
2620 * Irssi SILC Client sets the nicknames in nick@hostn format.
2621 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2622 irssi/src/silc/core/silc-core.c.
2624 The WHOIS printing now also shows both the real nickname and
2625 the formatted nickname so that user knows how to access the
2626 user if there are multiple same nicknames cached. Affected
2627 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2628 printing formatting too to take the hostname now as a separate
2629 argument. The Affected file is
2630 irssi/src/fe-common/silc/modules-formats.[ch].
2632 * Changed the silc_client_get_clients_local to accept the formatted
2633 nickname as argument. It accepts the real nickname too but the
2634 formatted nickname can be used to find the true entry from
2635 multiple entries. Affected file lib/silcclient/silcapi.h and
2636 lib/silcclient/idlist.c.
2638 * Added nickname_format_parse field to the SilcClientParams.
2639 It is a callback function provided by the application to parse
2640 the nickname out of the formatted nickname string. The library
2641 calls it to get the nickname from the formatted string. Since
2642 the application generally knows better the format of the nickname
2643 string it parses it instead of the library, even though library
2644 encodes the formatted string. If the callback function is not
2645 provided then the library will use the string as is. The
2646 affected file is lib/silcclient/silcapi.h.
2648 * All the nickname strings passed to the client library in
2649 commands are now expected to be formatted nickname strings.
2650 If the command does not support the formatted nickname string
2651 it will assume that the sent string is the actual nickname.
2652 Affected file lib/silcclient/command.c.
2654 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Added public key authentication support to OPER and SILCOPER
2657 commands in the client library. Affected file is
2658 lib/silcclient/command.c.
2660 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Changed the get_auth_methdod client operation to be asynchronous.
2663 It can be async if the application resolves the authentication
2664 method from the server during the negotiation. Added new
2665 SilcGetAuthMeth completion callback that the application will
2666 call after resolving the authentication method.
2668 Added function silc_client_request_authentication_method that
2669 the application can use to resolve the authentication method
2670 from the server. Added also SilcConnectionAuthRequest callback
2671 that the library will call after the server has replied. The
2672 application can call this function if it does not know the
2673 current authentication method.
2675 Affected files are lib/silcclient/client.c and
2676 lib/silcclient/silcapi.h.
2678 * The Irssi SILC client now automatically resolves the authentication
2679 method incase any configuration information is not present (and
2680 currently there never is). The affected file is
2681 irssi/src/silc/core/client_ops.c.
2683 * Fixed public key authentication from the client library.
2684 Affected file lib/silcclient/protocol.c. Changed also the
2685 protocol specification about the public key authentication in
2686 the connection authentication protocol. The actual data to be
2687 signed is now computed with a hash function before signing.
2689 * Fixed the public key authentication from the server as well.
2690 Affected file silcd/protocol.c.
2692 * Removed the mlock()'s from the memory allocation routines.
2693 Affected file lib/silcutil/silcmemory.c. The ./configure does
2694 not check anymore for the mlock(). Affected file is
2697 * Fixed USERS command in server to allow the execution of the
2698 command for private and secret channels if the client sending
2699 the command is on the channel. Affected file silcd/command.c.
2701 * Fixed silc_client_get_clients_local to return the clients
2702 count correctly. It could return wrong value. Affected file
2703 lib/silcclient/idlist.c.
2705 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2708 types. The assembler optimizations seemed not to like 64-bit
2709 data types. The assmebler optimizations thus are now enabled
2710 also for BSD systems as opposed to only enable them for Linux.
2712 * Do not check for threads at all on BSD systems. Affected
2713 file configure.in.pre.
2715 * Removed -n and -h options from the Irssi SILC Client since
2716 they are not used in silc.
2718 * Fixed the prime generation to assure that the first digit
2719 of the generated random number is not zero since our conversion
2720 routines does not like number strings that starts with zero
2721 digit. If zero digit is seen the random number is regenerated.
2722 This caused some corrupted RSA keys when the zero first digit
2723 was met. Affected file lib/silcmath/silcprimegen.c.
2725 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Fixed WIN32 configuration in the ./configure script.
2728 Fixed to include xti.h on environments that has it.
2729 Patches by Carsten Ilchmann and andrew.
2731 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2733 * Changed the silc_id_create_client_id to be collision
2734 resistant. It is now assured that there cannot be created
2735 two same client ID's. I suspect that some weird bugs in
2736 the server were actually caused by duplicate Client IDs.
2737 Affected file silcd/serverid.[ch]. A router receiving
2738 new ID now also assures and informs the sending server
2739 if the ID caused collision.
2741 * Changed the silc_id_create_channel_id to also assure that
2742 there are no collisions.
2744 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Statement about ignoring the Mutual Authentication flag when
2747 performing rekey with PFS was a bit misleading. It is ignored
2748 if it was set in the initial negotiation, it cannot be even
2749 set in the rekey. Fixed in the ke-auth draft. Started the
2750 new versions of the protocol drafts in the doc/.
2752 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Fixed a bug in silc_client_command_identify_save when saving
2755 new channel information. The channel name was no duplicated
2756 and caused crash on exit. Affected file is
2757 lib/silcclient/command_reply.c.
2759 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2761 * Fixed the getkey command handling in the server. Send just
2762 empty OK reply to the sender if the key could not be fetched
2763 (but everything else was ok, like the key just was not available).
2764 Changed the public key parameter to optional in the protocol
2765 specs so that empty OK reply can be sent. Affected file
2768 Added a message to Irssi SILC client to tell to user if the
2769 server did not return a public key.
2771 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Fixed a channel key regeneration bug. It registered new
2774 timeout tasks exponentially until all system resources were
2775 used. Affected file silcd/server.c.
2777 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Added the SILC Document generator to the scripts/silcdoc.
2780 It can be used to generate the Toolkit Reference Manual out
2781 of the source tree. Internally it will also use the RoboDoc
2782 generator now imported in util/robodoc.
2784 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Added couple of return's in rekey protocol if error orccurred
2787 during the protocol. The execution must be terminated.
2788 Affected file silcd/protocol.c. Also, terminate the protocol
2789 always with timeout.
2791 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * The client's Client ID was created initally from the wrong
2794 nickname (it could have been in format nick@host) in the
2795 silc_server_new_client. Affected file silcd/packet_receive.c
2797 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Added some SILC_LOG_ERROR's to various error conditions
2800 if client could not be added to ID cache. Affected files
2801 silcd/packet_receive.c and silcd/server.c.
2803 * When client's sock->user_data is freed, NULL also the
2804 client->router and client->connection pointers. Added check
2805 for these pointers being NULL to various places around the
2806 code. Affected file silcd/server.c.
2808 * Added client->data.registered == TRUE checks to various
2809 places around the code to assure that unregistered client's
2810 are not handled when it is not allowed. Affected file
2813 * Added `bool registered' fields to all
2814 silc_idlist_[server|client]_get_* routines to indicate whether
2815 the fetched client needs to be registered or not. Affected
2816 file silcd/idlist.[ch].
2818 * Add your own entry as registered to the ID cache in the
2819 server. Affected file server.c.
2821 * Fixed a bug in silc_server_new_server. The SilcServer was
2822 set as the new server's context instead of SilcServerEntry.
2823 This naturally caused some weird bugs.
2825 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Do not delete the channel rekey task when adding it
2828 for in silc_server_create_channel_key.
2830 * Changed the silc_server_create_channel_key to return
2831 TRUE or FALSE to indicate the success of the channel key
2834 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Fixed MSVC++ project files and added missing files to
2837 Makefiles under win32/.
2839 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Do not add TCP_NODELAY flag if the operating system
2842 does not have it defined. Affected files are
2843 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2845 * Fixed buffer overflow from Irssi SILC Client. Affected
2846 file irssi/src/fe-common/core/themes.c.
2848 * Fixed double free in client library in the file
2849 lib/silcclient/client.c when disconnecting from server.
2851 * Applied double free patch from cras to Irssi SILC client.
2852 Affected files irssi/src/core/[modules/expandos].c
2854 * Fixed the disconnection handling to Irssi SILC Client.
2855 The application must call silc_client_close_connection
2856 in ops->connect client operation in case of failure of
2857 the connection. Affected file is
2858 irssi/src/silc/core/client_ops.c.
2860 * Do not set sock->protocol to NULL in the function
2861 silc_client_close_connection after executing the protocol's
2862 final callback since the sock might not be valid anymore.
2863 Affected file lib/silcclient/client.c.
2865 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Do not enable SILC_THREADS if the linking with libpthread
2868 did not happen. Affected file configure.in.pre.
2870 * Added notion to protocol specification that server must
2871 verify the sent authentication payload with CMODE when
2872 setting the channel founder key. Implemented it to the
2873 server. Affected file silcd/command.c.
2875 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Added _EXTRA_DIST SILC distribution variable to the
2878 distributions file. It is used to conditionally add extra
2879 files or directories to the specific distribution. Affected
2880 files ./prepare, Makefile.am.pre and distributions.
2882 Removed the `_' from the start of the distribution names.
2885 * Added README.WIN32 for instructions to compile the Toolkit
2888 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2890 * Fixed a double free in disconnection in the server. Affected
2891 file is silcd/server.c.
2893 * Fixed the lib/silcske/groups.c to work now also with GMP
2894 MP library. The string conversion did not work when using
2895 specific base and the base is indicated in the string as well.
2897 * Created win32/ directory which now includes MSVC++ specific
2898 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2899 It will appear only in the toolkit distribution
2901 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Changed the key material distribution function in case when
2904 the hash output is too short. The data is now concatenated
2905 a bit differently than it used to. Made the change to the
2906 SKE protocol specification.
2908 * Added better GMP detection to configure.in.pre. A patch
2911 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Fixed a minor bug in SKE that might cause some problem on
2914 some platforms. Affected file lib/silcske/silcske.c.
2916 * Added the cookie checking for initiator in the SKE. It checks
2917 that the responder returns the sent cookie unmodified. The
2918 affected file is lib/silcske/silcske.c. Added new SKE
2919 error type INVALID_COOKIE that can be sent during the
2920 negotiation. Fixed some memory leaks as well.
2922 * Added the "invalid cookie" error message to Irssi SILC client's
2925 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Added `task_max' field to the SilcClientParams to indicate
2928 the maximum tasks the scheduler can handle. If set to zero,
2929 default values are used. Affected file lib/silcclient/silcapi.h.
2931 * Fixed memory leaks in silc_client_close_connection. Affected
2932 file lib/silcclient/client.c.
2934 * Added silc_client_del_client_entry to client library to free
2935 all memory of given client entry. Affected file is
2936 lib/silcclient/idlist.[ch].
2938 * Added new functions silc_client_del_channel and
2939 silc_client_del_server to delete channel and server entries.
2940 Affected file lib/silcclient/[silcapi.h/idlist.c].
2942 * Removed silc_client_del_client_by_id from silcapi.h.
2944 * Fixed the INFO command to return the server's own info
2945 correctly when querying by Server ID. Affected file is
2948 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Removed the non-blocking settings in WIN32 code in the
2951 silc_sock_[read/write] and added SleepEx instead. Affected
2952 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2953 of input data is now checked with FIONREAD and ioctlsocket.
2955 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Call silc_schedule_task_del_by_context in the
2958 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2959 Affected file lib/silccore/silcprotocol.c.
2961 * Call silc_protocol_cancel for active protocols in the
2962 silc_server_close_connection if the funtion
2963 silc_server_free_sock_user_data has not been called.
2964 Affected file silcd/server.c.
2966 * Generic tasks cannot be deleted using the del_by_fd
2967 task deleting function since generic tasks does not match
2968 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2970 * Added a notion to SILCOPER help file that the SILCOPER works
2971 only on router server, not on normal server.
2973 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Added for WIN32 support for the new scheduler as well.
2976 Affected file lib/silcutil/win32/silcwin32schedule.c.
2978 * Fixed the SHA1 implementation to work on various platforms.
2980 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2983 API. It is part of the scheduler now. Everything else is
2984 as previously but some functions has changed their names.
2985 Checkout the lib/silcutil/silcschedule.h for the interface.
2986 Updated all applications to use the new interface. Affected
2987 files are lib/silcutil/silcschedule.[ch].
2989 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Found a bug in the SKE implementation. The HASH value,
2992 specified by the protocol, was not computed correctly. The
2993 public key of the responder was not added to the computation
2994 even though it is mandatory. Affected file lib/silcske/silcske.c.
2995 This unfortunately causes incompatibilities with older
2996 clients and servers.
2998 * Added WIN32 specific network init and uninit functions:
2999 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3000 the Winsock2. Affected file lib/silcutil/silcnet.h and
3001 lib/silcutil/win32/silcwin32net.c.
3003 * Set the socket always to nonblocking mode on WIN32 after
3004 reading data or writing data. Affected file is
3005 lib/silcutil/win32/silcwin32sockconn.c.
3007 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Fixed various compilation problems under WIN32. Affected
3010 files lib/silcutil/win32/silcwin32thread.c and
3011 lib/silcutil/win32/silcwin32schedule.c.
3013 * Removed all _internal.h #includes from public header
3014 files. Internal headers must never be included from
3017 Removed also the lib/silcske/payload_internal.h file.
3019 * All include files that may be needed (public and some others
3020 included by the public headers) by application developers are
3021 now copied to the ./includes directory. It does not copy any
3022 internal headers. Affected file Makefile.defines.pre and all
3023 Makefile.am's under lib/ and subdirs.
3025 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Do not change the ~/.silc directory's permissions automatically.
3028 Affected file irssi/src/silc/core/clientutil.c.
3030 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3032 * Do not cancel the protocol in silc_server_close_connection
3033 it might cause recursion. Now cancelled in the function
3034 silc_server_free_sock_user_data. Affected file silcd/server.c.
3036 * Fixed the silc_server_remove_clients_by_server to regenerate
3037 the channel keys correctly finally. Added also new function
3038 silc_server_remove_clients_channels to actually do it.
3039 Affected file silcd/server.c.
3041 * Fixed the silc_server_new_channel to not crash by giving
3042 wrong router to the new channel. Affected file is
3043 silcd/packet_receive.c.
3045 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3048 which is given as argument to the silc_client_alloc now.
3049 It can be used to configure the client and set various parameters
3050 that affect the function of the client.
3052 * The USERS command in server did not check whether the channel
3053 is private or secret. Affected file silcd/command.c.
3055 * Added new argument to the USERS command in protocol specification.
3056 The USERS command now can take the channel name as argument
3057 as well. Added support for this in client and server and
3058 updated the protocol specs.
3060 * Completed the GETKEY command in client. It can be now used
3061 to fetch also servers public key not only some clients.
3062 Affected files lib/silcclient/command[_reply].c.
3064 * Added silc_client_get_server to return server entry by the
3065 server name. Affected files lib/silcclient/silcapi.h and
3068 * Redefined the IDENTIFY command in protocol specification to be
3069 more generic. It now can be used to query information about
3070 any entity in the SILC Network, including clients, servers and
3071 channels. The query may be based either the entity's name
3072 or the ID. Added support for this in both client and server.
3074 Affected files silcd/command.c and lib/silcclient/command.c
3075 and command_reply.c.
3077 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3078 the _from_client and _from_server functions. Affected file
3081 * Added silc_client_get_channel_by_id_resolve to the file
3082 lib/silcclient/silcapi.h to resolve channel information by
3083 its ID. Added also silc_client_get_channel_by_id that
3084 does not resolve it from the server.
3086 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Added SilcServerEntry context into the client library
3089 to represent one server. The INFO command now allocates
3090 these to save the resolved server info. For now on the
3091 client library will also keep information about servers,
3092 connected and resolved with INFO.
3094 The INFO command now allocates the SilcServerEntry context
3095 and saves the server info there. The COMMAND_REPLY in
3096 the INFO now returns the parameters to application in
3097 same order as defined in the protocol specification.
3099 The entries are cached in the client->server_cache.
3101 * The INFO command is now issued after received the Client ID
3102 from the server. Affected file lib/silcclient/client.c.
3104 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3105 to the application as the mode changer might be server.
3106 It is guaranteed that NULL is not returned anymore to the
3107 application. Affected file lib/silcclient/client_notify.c.
3109 The ID Type is now also passed to the application so that
3110 it can check whether the returned entry is SilcClientEntry
3113 Added new function silc_client_get_server_by_id to return
3114 the server entry by ID. Affected files are the
3115 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3117 * Do not create the channel in the Irssi SILC Client when issuing
3118 the JOIN command but when received the sucessful JOIN command
3119 reply. Otherwise the channel might get created even though we
3120 could not join it. The Affected file is
3121 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3123 * Fixed a channel joining bug in router. The router must also
3124 check the channel modes, invite and ban lists etc. when serving
3125 the JOIN command sent by normal server. Affected file is
3126 silcd/command.c. The router now resolves the client's
3127 information from the server who sent the JOIN command if it
3128 does not know it, and processes the JOIN command only after
3131 * Changed the SilcCommandCb to take new argument; void *context2.
3132 Affected file lib/silccore/silccommand.h
3134 The second argument in the command callbacks in the server now
3135 includes the SilcServerCommandReplyContext if the command was
3136 called as pending command callback from the command reply.
3137 Otherwise it is NULL. When called as pending the status of the
3138 command reply will be checked and if it was erronous the
3139 error will be sent to the original sender of the command.
3140 This way the client always receives the error messages even
3141 though the server was actually the one who received the error
3142 when it resent the command to router, for example. Affected
3143 files silcd/command[_reply].[ch].
3145 * Fixed sending WHOWAS command's error message to client if
3146 the requested client could not be found. It was missing.
3149 * Changed the CMODE and CUMODE commands reply arguments in the
3150 protocol specification. The Channel ID is now sent in both
3151 of the commands to identify the channel. Implemented this
3152 new feature to the client and server. Affected files
3153 lib/silcclient/command_reply.c and silcd/command.c.
3155 * Made better checks for invite and ban lists in the JOIN
3156 command in server. Affected file silcd/command.c.
3158 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3160 * The server now performs the incoming host IP/DNS lookup
3161 using the silc_socket_host_lookup and thus does not block
3162 the server anymore. Affected file silcd/server.c.
3164 * Completed the multi-thread support for SILC Scheduler in
3165 the lib/silcutil/silcschedule.c.
3167 * Fixed the configure.in.pre to detect the pthread correctly
3170 * Fixed a deadlock in silc_task_queue_wakeup in the file
3171 lib/silcutil/silctask.c.
3173 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Added new function silc_schedule_wakeup that is used in
3176 multi-threaded environment to wakeup the main thread's
3177 schduler. It needs to be used when a thread adds a new task
3178 or removes a task from task queues. After waking up, the
3179 scheduler will detect the task queue changes. If threads
3180 support is not compiled in this function has no effect.
3181 Implemented the wakeup mechanism to both Unix and WIN32
3182 systems. Affected files are lib/silcutil/silcschedule.[ch],
3183 lib/silcutil/unix/silcunixschedule.c and the
3184 lib/silcutil/win32/silcwin32schedule.c.
3186 * Added new function silc_task_queue_wakeup to wakeup the
3187 scheduler by the specified task queue. Affected file
3188 lib/silcutil/silctask.[ch].
3190 * The silc_socket_host_lookup_start now wakes up the scheduler
3191 after adding the timeout task. Affected file is
3192 lib/silcutil/silcsockconn.c.
3194 * The silc_socket_host_lookup is synchronous now if the threads
3195 support is not compiled in. However, the callback is still
3196 called asyncronously through the scheduler, anyway. Affected
3197 file lib/silcutil/silcsockconn.c.
3199 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Added new function silc_socket_host_lookup to perform
3202 asynchronous IP and FQDN lookups for the socket connection.
3203 Affected files lib/silcutil/silcsockconn.[ch].
3205 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3208 that may or may not compile the mutex support in.
3210 Changed the silc_mutex_alloc interface. It allocates the
3211 mutex now to the sent pointer and returns TRUE or FALSE.
3213 Affected file lib/silcutil/silcmutex.h.
3215 * Wrote the SILC Task Queue interface to support multi-threads.
3216 Affected file lib/silcutil/silctask.[ch].
3218 * Wrote the SILC Scheduler to support multi-threads. Affected
3219 file lib/silcutil/silcschedule.c.
3221 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3224 in lib/silcutil/win32/.
3226 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3228 * Defined SILC Mutex API and SILC Thread API and implemented
3229 them for Unix. Affected files are
3230 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3231 lib/silcutil/unix/silcunixmutex.c and
3232 lib/silcutil/unix/silcunixthread.c.
3234 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3236 * Fixed the silc_server_remove_clients_by_server's channel
3237 key re-generation. The hash table handling was incorrect
3238 and would not work with many channels. Affected file is
3241 * Fixed some memory leaks around the server code.
3243 * Rewrote the silc_server_get_users_on_channel to support IPv6
3244 based Client ID's. Affected file silcd/server.c.
3246 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3247 specification. However, a separate document must be written
3248 to define the detailed signing procedure and the payload
3249 associated with the flag. Defined the flag to the
3250 lib/silccore/silcchannel.h as well.
3252 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Changed the dynamic tables to static size tables in the
3255 lib/silccrypt/silchmac.c.
3257 * Removed GCC dependencies from the code. A patch by cras.
3259 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Do not show the error "Error receiving packet bla bla"
3262 in server if it really was not an error (-2 means that reading
3263 is pending). Affected file silcd/server.c.
3265 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Fixed a possible crash in silc_server_remove_clients_by_server
3268 in silcd/server.c. Fixed there also some memory leaks.
3270 * Fixed the silc_idlist_replace_client_id. It could replace
3271 wrong key in the hash table. Affected file silcd/idlist.c.
3273 * Do not check whether there are global users on the channel
3274 if the channel->global_users is FALSE. Affected functions
3275 silc_server_remove_from_one_channel and
3276 silc_server_remove_from_channels in silcd/server.c. Also,
3277 do not check if the removed client is local as we can be
3278 sure that global client was not removed from the channel
3279 and checking for global users is not needed.
3281 * The silc_server_remove_clients_by_server now re-generates
3282 the channel keys correctly for those channels that had
3283 clients removed from them. Affected file silcd/server.c.
3285 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * Found the reason of random crashes in the server. We weren't
3288 ignoring the SIGPIPE signal (which can be sent in write())
3289 and it crashed the server. Affected file silcd/silcd.c.
3291 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Assure that sock->user_data is not NULL in the function
3294 silc_server_packet_send in silcd/packet_send.c.
3296 * Disconnect the remote connection if it could not be added
3297 to any ID lists in the server. The affected file is
3300 * Check in silc_server_packet_send[_real/dest] that the
3301 socket is not disconnecting and ignore the data if it is.
3302 Affected file silcd/packet_send.c.
3304 * Define inline to __inline on native WIN32 compilation.
3305 Affected file includes/silcwin32.h.
3307 * Added some explicit type casts for inline code since MSVC
3308 require them. Affected files lib/silcutil/silcbuffer.h,
3309 lib/trq/silcdlist.h and lib/trq/silclist.h.
3311 * Print warning in log files from now on if the packet
3312 decryption fails. Affected file silcd/server.c.
3314 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * Changed the `say' client operation's interface to accept
3317 new `type' argument to indicate the type of the message sent
3318 by the library. The application may filter the library's
3319 messages according the type. The affected file is the
3320 lib/silcclient/silcapi.h.
3322 * Added two new functions to lib/silcclient/silcapi.h:
3323 silc_client_del_client and silc_client_del_client_by_id.
3324 Affected file lib/silcclient/idlist.c.
3326 * Moved the clientincludes.h from includes/ to silc/ and
3327 serverincludes.h from includes/ to silcd/.
3329 * The modes for the CMODE and CUMODE are now passed as
3330 uint32 for application with COMMAND_REPLY. The affected
3331 file is lib/silcclient/command_reply.c.
3333 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3335 * /WHOIS without arguments shows client's own information.
3336 Affected file lib/silcclient/command.c.
3338 * Changed PING to not accept any arguments. The specs
3339 says that client can ping only the connected server so
3340 requiring an argument is not needed. Affected file is
3341 lib/silcclient/command.c.
3343 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Fixed a fatal bug in private message sending and reception
3346 encryption and decryption when using private message keys.
3347 The implementation was incorrect and did not follow the
3348 specification. It causd that some of the message were
3349 lost since it did not use the sending and receiving keys
3350 as the protocol suggests. This has been fixed and will cause
3351 incompatibilities with older clients when sending private
3352 message encrypted with private message keys. Affected files
3353 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3354 and various other in Irssi SILC Client.
3356 Added `responder' boolean argument to the functions
3357 silc_client_add_private_message_key[_ske] to indicate when
3358 the key is added as responder or initiator of the key
3361 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Removed the silc_ske_check_version function and created
3364 a SilcSKECheckVersion callback. Added also a function
3365 silc_ske_set_callbacks that is now used to set all SKE
3366 callbacks. The callback functions are not given to
3367 the SKE functions anymore, but this function is used to
3370 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3372 * Added `silc_version' argument to the silc_client_alloc
3373 to define the version of the application for the library.
3374 The library will use the version string to compare it
3375 against the remote host's (usually a server) version
3376 string. Affected file lib/silcclient/silcapi.h
3378 * Added the KE protocol context to Key Agreement context
3379 in client library so that we can abort the SKE if it
3380 is in process when we get timeout. Affected file is
3381 lib/silcclient/client_keyagr.c.
3383 * Do not resolve the client ID forever if it returns in the
3384 first time that such client does not exist. This was done
3385 for example with private message. Affected file is
3386 lib/silcclient/client_prvmsg.c.
3388 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Do not add regex.h for WIN32. The affected file
3391 includes/silcincludes.h.
3393 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3394 not work yet 100%. It generates the DLL's automatically
3395 when compiling with --with-win32 under cygwin.
3397 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * lib/contrib/regex.c is not compiled on WIN32.
3401 * Added silc_net_get_socket_opt function to the
3402 lib/silcutil/silcnet.h.
3404 * Added includes/silcwin32.h for WIN32 specific includes
3407 * Do not use ptime structure or any of the posix process
3408 functions on WIN32 in lib/silccrypt/silrng.c.
3410 * Added silc_gettimeofday to provide generic function
3411 for struct timeval on all platforms. Added the function
3412 to lib/silcutil/silcutil.h.
3414 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3417 library as they clearly belong there. As a plus side we
3418 can make the actual socket connection routines platform
3421 Added also new generic function silc_socket_read and
3422 silc_socket_write (that used to be silc_packet_[read/write].
3423 The implementation of these are platform specific.
3425 * Added WIN32 specific routines of silc_socket_[read/write]
3426 to lib/silcutil/win32/silcwin32sockconn.c.
3428 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Added preliminary support for native WIN32 compilation under
3431 cygwin (using the -mno-cygwin option for GCC) to the
3432 ./configure.in.pre. The --with-win32 now prepares the
3433 compilation for native WIN32.
3435 * Rewrote the SILC Scheduler interface in the file
3436 lib/silcutil/silcschedule.h. The scheduler is now context
3437 based and does not have anymore any global static scheduler.
3438 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3439 and created lib/silcutil/win32 directory for WIN32 based
3442 * Added Unix specific network routines to the
3443 lib/silcutil/unix/silcunixnet.c and the old
3444 lib/silcutil/silcnet.c includes now only generic routines.
3446 Added WIN32 specific network routines to the
3447 lib/silcutil/win32/silcwin32net.c.
3449 * Added Unix specific utility functions from the
3450 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3452 * Added WIN32 SILC Scheduler to the file
3453 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3456 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3458 * Do not handle JOIN notify in the server if the target client
3459 is not registered (idata->registered == FALSE). The affected
3460 file is silcd/packet_receive.c.
3462 * Update the nickrec->founder in event_cumode in the Irssi SILC
3463 client. Affected file irssi/src/silc/core/silc-channels.c.
3465 * Fixed the CUMODE_CHANGE notify handling in the server when
3466 server and router are announcing their clients on channels.
3467 Now the mode changes are saved and notified correctly. The
3468 affected file is /silcd/packet_receive.c.
3470 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3471 They really did not replace the cache entry in the ID Cache.
3472 Now they do that. Affected file silcd/idlist.c.
3474 * Fixed the KICK notify handling in the Irssi SILC client to
3475 update the channel records so that the kicked client does not
3476 appear to be on the channel. The affected file is
3477 irssi/src/silc/core/silc-channels.c.
3479 * Always update the conn->current_channel when executing command
3480 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3482 * Fixed the KILL notify handling in Irssi SILC client to remove
3483 the killed client on all channels.
3485 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Fixed the silc_parse_command_line to remove extra spaces
3488 from the start and end of the arguments. Affected file is
3489 lib/silcutil/silcutil.c.
3491 * Cancel and free any active protocol in the function
3492 silc_server_close_connection. Affected file silcd/server.c.
3494 * Cancel and free any active protocol in the function
3495 silc_client_close_connction. Affected file is
3496 lib/silcclient/client.c.
3498 * Do not execute the KILL command for clients that are in
3499 history (ie. they are not in the network). Affected file is
3502 * Fixed KILL notify handling, client does not crash anymore.
3503 Affected file irssi/src/silc/core/silc-channels.c.
3505 * Reduced the default packet buffer size from 2048 to 1024 in
3506 lib/silccore/silcpacket.c.
3508 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3509 counter to the SKE context that is incresed when the SKE library
3510 performs async operation outside the library. If the outside
3511 process frees the SKE context and FREED status will be set
3512 and the library will detect after the sync operation that the
3513 libary is freed. The affected files are
3514 lib/silcske/silcske[_status].[ch].
3516 * Resolve the client entry information in the function
3517 silc_client_channel_message to assure that NULL pointer is not
3518 passed as client entry to the application. */
3520 * Fixed the task timeout calculation to assure that there is
3521 never negative timeouts. The affected file is
3522 lib/silcutil/silcschedule.c.
3524 * Fixed the channel user mode notification sending in server.
3525 It was sent point-to-point to the router (or to server by router)
3526 but it needs to be destined to a channel. The routines now
3527 supports sending the channel user mode notifys to the channels
3528 when announcing clients and channels. Affected files are
3529 silcd/server.c and silcd/packet_receive.c.
3531 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3532 It did not actually replace the old channel entry in the cache.
3533 Affected file lib/silcclient/client_notify.c.
3535 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Fixed a possible crash in silc_packet_send_prepare. It now
3538 assures always that there is enough space in the buffer and
3539 at the tail area of the buffer (for MAC).
3541 Fixed the inbound buffer reallocation in silc_packet_read.
3542 It was old code and did not handle the reallocation correctly.
3545 The affected file is lib/silccore/silcpacket.c.
3547 * Fixed buffer overflow in silc_parse_nickname in the file
3548 lib/silcutil/silcutil.c.
3550 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * make install generates new server keys only if there is not
3555 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3558 Added check that if the NOREPLY is set then we will not send
3559 the away message. This avoids infinite loop of away messages
3560 if both clients are away. The affected file is
3561 lib/silcclient/client_prvmsg.c.
3563 * Fixed client crash if /NICK was given without arguments.
3564 Affected file lib/silcclient/command.c.
3566 * Server does not send the invite list in INVITE command back
3567 to the client if the list was not altered. Added this notion
3568 to the protocol spec as well. Affected file silcd/command.c.
3570 Fixed possible crash in INVITE command by checking the
3571 value of silc_server_get_client_route command.
3573 * Fixed the INVITE notify type handling. The arguments are now
3574 taken in correct order and client does not crash. The affected
3575 file is irssi/src/silc/core/silc-channels.c.
3577 Removed the "Inviting xxx to channel" message from the
3578 client library away and let the application handle it.
3579 Affected file lib/silcclient/command.c. Added that message
3580 to Irssi SILC client's message formats.
3582 * Fixed CMODE command crash in client. It now checks the
3583 amount of arguments correctly and does not crash. The affected
3584 file is lib/silcclient/command.c.
3586 * Do not create new channel automatically in silc_channels_join
3587 but check whether the channel by that name already exists.
3588 Affected file irssi/silc/core/silc-channels.c.
3590 * Do not send the SERVER_SIGNOFF to router if the disconnected
3591 entity was the router. Affected file silcd/server.c.
3593 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3594 SILC client as it was missing from there.
3596 Added the handling of the KICK notify to the Irssi SILC client
3597 as it was missing. Added "you have been kicked" message to
3598 Irssi SILC client's message modules formats.
3600 Added the handing of the KILL notify to the Irssi SILC client
3601 as it was missing. Added the kill message module formats
3604 The affected file is irssi/src/silc/core/silc-channels.c.
3606 * The router did not save the channel mode the server announced.
3607 Affected file silcd/packet_receive.c.
3609 * Fixed a possible crash in INFO command in server. If the
3610 server did not provide the server info it crashed. Affected
3611 file silcd/command.c.
3613 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Fixed the GETKEY command in the server to check also the
3616 global list. Otherwise the GETKEY would not work correctly
3617 in normal SILC server. Affected file silcd/command.c.
3619 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Fixed GETKEY crash, it crashed if the command did not succseed.
3623 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3626 is now real and not just an macro interface to GMP.
3628 Removed the entire GMP from the source tree and imported new
3629 NSS MPI library instead. Reason for removing GMP is that it is
3630 extremely large and compiles extremely slow. The NSS MPI
3631 is only a few files and compiles in less than 10 seconds.
3632 The speed is also about the same as GMP. The MPI is imported
3633 to lib/silcmath/mpi.
3635 If the system has GMP installed we will still use the GMP.
3636 If it is not then the NSS MPI will be compiled.
3638 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Merged a long nickname (127 characters long) crash bugfix from
3641 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3643 * Merged a freed memory reference bugfix from Irssi CVS tree.
3644 Affected file irssi/src/core/commands.c.
3646 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added the server's public key sving and verification to the
3649 server when performing the SKE. This was missing and the
3650 remote server's (or router's) public key was accepted without
3651 checking whether we have it previously or trust it at all.
3652 Affected file silcd/protocol.c.
3654 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Check in the silc_server_timeout_remote if protocol is active
3657 and make sure that the protocol's final callback is called so
3658 that all memory if freed. Affected file silcd/server.c.
3660 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * silc_server_whois_send_reply crashed the server if the nickname
3663 was 127 characters long. Affected file silcd/command.c.
3665 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Added sanity check to the silc_server_new_client. If the hostname
3668 is provided inside username then check that the provided hostname
3669 really is the same as the resolved one. If the hostname was not
3670 resolved then check it from the public key. Affected file is
3671 silcd/packet_receive.c.
3673 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3674 if the server disconnected us and the connection is not valid
3675 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3677 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3678 the library to the lib/silcutil/silcutil.[ch].
3680 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Close log file after open. Affected file
3683 lib/silcutil/silclog.c.
3685 * Check whether sock == NULL in silc_client_send_packet and return
3686 if it is. Affected file lib/silcclient/silcclient.c.
3688 * Check rec->entry == NULL in the Irssi SILC Client before
3689 sending the channel message. Affecte file is
3690 irssi/src/silc/core/silc-servers.c.
3692 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Merged a splitted window bugfix from Irssi CVS tree. The
3695 affected file is irssi/src/fe-text/textbuffer-view.c.
3697 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3698 It did not print nickname.
3700 * Improved the distributions system a bit.
3702 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3705 irssi/src/fe-text/gui-window.c.
3707 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3708 to in-active server. The affected file is
3709 irssi/src/silc/core/client_ops.c.
3711 * Resolve the client in USERS command reply if the entry does
3712 not have username resolved. The affected file is
3713 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3714 command to WHOIS command to really resolve stuff. The USERS
3715 is not used any more in any critical section so WHOIS can
3716 be used even though it might be slower than IDENTIFY.
3718 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3721 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Changed the protocol API a bit more consistent in the
3724 lib/silccore/silcprotocol.[ch].
3726 * Changed the following headers to ROBODoc format:
3728 lib/silccore/silcpayload.h
3729 lib/silccore/silcprotocol.h
3730 lib/silccore/silcsockconn.h
3732 All core library headers are now formatted.
3734 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3736 * Fixed a bug in Irssi SILC client; do not show that you are
3737 server/router operator if you really are not. Affected file is
3738 irssi/src/silc/core/client_ops.c.
3740 * Renamed silc_command_free_payload to silc_command_payload_free.
3741 Affected file lib/silccore/silccommand.h
3743 * Added silcmath.h to include the prototoypes of various routines
3744 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3747 * Changed the following headers to ROBODoc format:
3749 lib/silccore/silcchannel.h
3750 lib/silccore/silccommand.h
3751 lib/silccore/silcid.h
3752 lib/silccore/silcidcache.h
3753 lib/silccore/silcmode.h
3754 lib/silccore/silcnotify.h
3755 lib/silccore/silcpacket.h
3756 lib/silcmath/silcmath.h
3758 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Added checking to the server code not to start the server if
3761 ciphers and stuff are not configured properly. Affected files
3762 silcd/serverconfig.[h] and silcd/server.c.
3764 * Changed the layout of the header files of the public interfaces
3765 in the SILC libraries. The new layout supports ROBODoc
3766 documentation tool (and some others) so that it is easy to create
3767 a library reference manual. All the other headers and source
3768 code must still follow the CodingStyle document. Also source
3769 code must not include these ROBODoc stuffs, only the headers.
3770 Furthermore, all public interface headers must now be named
3771 by using `silc' prefix, example: silcapi.h, silccipher.h.
3772 Some files were renamed due to this. All the other headers
3773 must not be used as public interfaces. I will update the
3774 CodingStyle document later. Changed following headers, so far:
3776 lib/silcclient/silcapi.h
3777 lib/silccore/silcauth.h
3778 lib/silccore/silcprivate.h
3779 lib/silccrypt/silcdh.h
3781 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Removed silc_client_packet_send_flush from the client library
3786 as it is not needed. Affected file lib/silcclient/client.[ch].
3788 * Added printing of message of unresolved authentication method
3789 to the Irssi SILC client. Added it to the module formats.
3790 Removed the same message from the client library.
3792 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Added new distribution feature, DISTLABEL. Every distribution
3795 can define own preprocessor label that can be used in the
3796 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3797 file distributions, acconfig.h.pre and prepare.
3799 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Added Makefile.defines_int to include the actual definitions
3802 for Makefile.defines.in. Tested the new distribution system,
3803 created distributions and tested installation.
3805 * Added AWAY message printing to the Irssi SILC client. Added
3806 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3808 * Added SCONNECT command to call the SILC's CONNECT command.
3809 Cannot use CONNECT directly since Irssi uses that internally.
3810 Affected file irssi/src/silc/core/silc-servers.c.
3812 Added ACTION local command. It is same as ME command but takes
3813 the channel as mandatory argument.
3815 Rewrote some of the Irssi's help files to suite for SILC
3818 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Added Makefile.defines[.in] that should for now on be included
3821 in all Makefile.am file in the source tree. That file includes
3822 all common compilation definitions for SILC source tree.
3824 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Minor changes to the ./prepare script to change the package
3827 name according the distribution name to the configure.in.
3829 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Created new distribution system. Added file `distributions'
3832 that defines all the distributions that can be created out of
3833 the SILC source tree. The ./prepare script now reads that
3834 file to determine how to prepare the distributions. The
3835 first argument to the ./prepare is the name of the distribution
3836 and second is the version of the distribution. If given
3837 without arguments it creates the default (toolkit) distribution
3838 with the default version (defined in ./prepare).
3840 All Makefile.am files that are subject to the distributions
3841 are now named as Makefile.am.pre. These are ./Makefile.am
3842 and lib/Makefile.am. Others may be changed later.
3844 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3846 * Added invite list, ban list, some key management and connection
3847 error message printing to module formats in the Irssi SILC client.
3849 * Added new silc_client_set_away_message to set the away message
3850 that is back to the person who sent private message. The
3851 affected file lib/silcclient/silcapi.h and the
3852 lib/silcclient/client_prvmsg.c.
3854 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3856 * Fixed the private message sending in the Irssi SILC client,
3857 added local command KEY to the Irssi SILC client.
3859 Added key management and key agreement message formats to the
3860 irssi/src/fe-common/silc/module-formats.[ch].
3862 Added USERS (alias WHO) printing, server/router operator
3863 indication and LIST command printing to the module formats.
3865 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Fixed channel joining notify handling, cumode notify handling
3868 from Irssi SILC client.
3870 * Added SILC specific module-formats to the Irssi SILC client so
3871 that SILC specific message hilighting, colors etc is possible.
3872 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3874 Added channel mode, channel user mode, actions, notices,
3875 whois and whowas printing to the the module-formats.c.
3877 * Fixed a bug in channel deletion in the server. The channel
3878 is not left to the cache even if the channel founder auth mode
3879 is set when there are no users anymore on the channel. Affected
3880 file silcd/server.c.
3882 * The silc_net_localhost now resolves the entire hostname including
3883 the domain name. Affected file lib/silcutil/silcnet.c.
3885 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Changed the ask_passphrase client operation to be ascynchronous.
3888 It has now a completion callback and a context that the
3889 application must call after it has got the passphrase from
3890 the user. Affected files lib/silcclient/silcapi.h,
3891 lib/silcclient/protocol.c, lib/silcclient/command.c and
3894 Added SilcAskPassphrase callback that the application calls
3895 to deliver the passphrase to the library.
3897 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3898 The public key verification and especially a certificate
3899 verification is asynchronous procedure.
3901 Added new SILC_SKE_STATUS_PENDING status to indicate the
3902 request is pending and a callback will be called to finalize
3905 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3906 indicate that remote end did not send its public key (or
3907 certificate), even though we require it. Added check for this
3908 condition in the SKE. This was a security bug, now fixed.
3910 Defined new SilcSKEVerifyCbCompletion callback that is called
3911 when the verification process is completed.
3913 The affected files lib/silcske/silcske_status.h and
3914 lib/silcske/silcske.[ch].
3916 * Changed the verify_public_key client operation to be async
3917 as well. Defined SilcVerifyPublicKey callback that is used to
3918 indicate the success of the public key verification process.
3920 Changed the server and client to use the new async client
3923 * Changed the Irssi SILC client's internal scheduler to be called
3924 twice as many times as it used to be. As a result the client
3925 should be a bit faster now. Affected file is
3926 irssi/src/silc/core/silc-core.c.
3928 * Added support to Irssi SILC client of asynchronous public key
3929 verification and passphrase inquiry. Affected file is
3930 irssi/src/silc/core/silc-core.c.
3932 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3934 * Do not say "You have left channel %s" in client library.
3935 Moved it to the application. Affected files are
3936 lib/silcclient/command.c and silc/client_ops.c.
3938 * Fixed silc_client_get_clients. Command context was not
3939 duplicated and was freed memory in the callback. Affected
3940 file lib/silcclient/idlist.c.
3942 * Do not say "you are now talking..." on JOIN command in the
3943 client library. The appliation must handle it.
3945 * Do not say ".. changed topic to" in command reply in the
3946 client libary. The application must handle it.
3948 * Fixed TOPIC command sending in the client library.
3950 * Fixed a memory leak in silc_client_command_free in the file
3951 lib/silcclient/command.c.
3953 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Imported a modified version of Irssi client to the source tree.
3956 The Irssi will be used to create a new client called
3957 Irssi SILC. Imported to irssi/.
3959 Added silc_core_init_finish function to the Irssi. Affected
3960 file irssi/configure.in.
3962 A lot changes in the Makefile.ams around the irssi tree.
3964 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Do not rehash if the new size is same as the old size of the
3967 hash table, in the silc_hash_table_rehash*. The affected file
3968 lib/silcutil/silchashtable.c.
3970 * Replaced hash_table_del_by_context calls from the server
3971 (when channel->user_list and client->channels) to the
3972 hash_table_del as it is sufficient and faster.
3974 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added silc_hash_table_list, silc_hash_table_get and the
3977 SilcHashTableList structure to provide an alternative way to
3978 traverse the hash table. The affected files are
3979 lib/silcutil/silchashtable.[ch].
3981 * Changed the server's idlist routines to use the hash table
3982 routines to optimize the code.
3984 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3986 * Replaced the client entry's `channel' list and channel entry's
3987 `user_list' list to hash tables for optimized lookup. Changed
3988 the code to use the hash table interface around the code.
3989 Affected file lib/silcd/idlist.[ch].
3991 * Added `auto_rehash' boolean argument to the function
3992 silc_hash_table_alloc to indicate whether the hash table should
3993 auto-rehash when it thinks is appropriate time. It will
3994 increase the hash table size if the there is twice as much
3995 entries in the table than the size of the table, and will
3996 decrease the size if there are twice as less entries than
3997 the size of the table.
3999 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4003 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * silc_idcache_purge_by_context deletes the entry now by context
4006 as it is supposed to do. Affected file lib/silccore/idcache.c.
4008 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4009 client is not anymore valid (WHOWAS givens the info) and not
4010 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4012 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Removed the `data' and `data_len' arguments from the ID Cache
4015 interfaces and added `name' argument. ID Cache does not handle
4016 anymore the binary data only a names associated with given ID.
4018 * When hashing a Client ID with silc_hash_id the entire ID is
4019 not hashed anymore, instead only the hash of the Client ID is
4020 hashed. This way we can access the Client ID from the cache
4021 with Client ID but with the hash of the ID (which is a hash of
4022 the nickname) as well without any difference in performance.
4024 Added also silc_idcache_find_by_id_one_ext to do one on one
4025 searching when we have the actual ID. Added also function
4026 silc_hash_client_id_compare. The affected files are
4027 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4029 * When hashing the name associated with a ID it is always done
4030 in lowercase. This way we can access the cache without worrying
4031 about case-sensitivity, even though, for example nicknames are
4034 * Fixed a bug in server with channel message sending. It put
4035 wrong ID type as destination ID. The affected file
4036 silcd/packet_send.c.
4038 * silc_idcache_del_by_context now deletes from all hash tables
4039 by context. Affected file lib/silccore/idcache.c.
4041 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Changed the client library to use the new ID Cache interface.
4044 Changes around the source tree.
4046 * Added silc_hash_table_rehash_ext to rehash with specific
4047 hash function. Affected file lib/silcutil/silchashtable.[ch].
4049 * Added silc_hash_string_compare to compare two strings in the
4050 hash table. Affected file lib/silcutil/silcutil.[ch].
4052 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Added new function silc_idcache_del_by_context into the
4055 lib/silccore/idcache.[ch].
4057 * Changed the server's ID list routines to use the new ID Cache
4058 interface. Changes around the source tree.
4060 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Added silc_hash_table_del[_by_context]_ext functions in to the
4063 lib/silcutil/silchashtable.[ch].
4065 Removed silc_hash_table_find_all* routines and added new
4066 silc_hash_table_find_foreach to replace them.
4068 Added silc_hash_table_replace_ext function as extended
4069 replacing function. Separated the simple hash table interface
4070 from the extended hash table interface in the file
4071 lib/silcutil/silchashtable.h.
4073 * Fixed minor bugs and changed it to use some of the new
4074 hash table functions in lib/silccore/idcache.c
4076 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Added new function silc_hash_table_find_all to return all keys
4079 in the hash table by the specified key. As the hash table is
4080 collision resistant it also makes it possible to have several
4081 duplicate keys in the hash table. This function may be used to
4082 find all of the keys from the hash.
4084 Added user_context arguments to the SilcHashFunction,
4085 SilcHashCompare and SilcHashDestructor to deliver user specified
4088 Added new fuctions silc_hash_table_find[_all]_ext to do
4089 extended lookup with specified hash and compare functions and
4090 specified user contexts.
4092 Added new function silc_hash_table_add_ext to add the key
4093 with specified hash function and user context.
4095 Added new function silc_hash_table_foreach to traverse all
4096 entrys in the hash table. Added SilcHashForeach callback
4099 Added new function silc_hash_table_del_by_context to delete
4100 the entry only if the context associated with the key matches.
4102 Affected files are lib/silcutil/silchashtable.[ch].
4104 * Removed silc_hash_[server/client/channel]_id and added just
4105 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4106 silc_hash_id_compare to compare two ID's using as the hash table
4107 comparison function. Added also silc_hash_data to hash
4108 binary data and silc_hash_data_compare to compare it.
4110 * Removed silc_idlist_find_client_by_hash as it is not needed
4111 anymore. Affected file silcd/idlist.[ch].
4113 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4114 to use internally the SilcHashTable. The new ID Cache is a lot
4115 faster than the old one. Some of the ID Cache interface was also
4116 rewritten and obsolete and stupid functions were removed.
4118 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Added entry_count field to the SilcHashTable to keep the number
4121 of the entries in the table. Implemented the function
4122 silc_hash_table_rehash. Added new function
4123 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4125 Fixed a minor bug in silc_hash_table_free.
4127 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4128 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4129 into the lib/silcutil/silcutil.[ch].
4131 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Implemented a collision resistant hash table into the
4134 lib/silcutil/silchashtable[ch]. See the header and the source
4135 for the SilcHashTable API.
4137 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Merged dotconf version 1.0.2 into lib/dotconf.
4141 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Do not compile anything in lib/silcsim/* if the SIM support
4144 is not enabled. The tree should now compile without problems
4147 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Compiled the SILC under cygwin. Compiled and tested briefly
4150 without problems. More tests needed. The SIMs didn't compile
4153 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4155 * Fixed possible crash in silc_get_username in the
4156 lib/silcutil/silcutil.c.
4158 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Fixed a va_arg in silc/client_ops.c.
4162 * Oops, RC5 routines were named AES and caused some problems
4163 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4165 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Added new SilcIDIP structure into the lib/silccore/id.h and
4168 replaced the old `ip' fields from all SILC ID's to that type.
4169 This is a step towards IPv6 support.
4171 The silc_id_get_len takes now the ID as an extra argument.
4172 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4173 both IPv4 and IPv6 based ID's.
4175 The affected files are lib/silccore/id.[ch] and other files
4176 around the tree using these routines.
4178 * Removed the ID length arguments in server from various
4179 silc_server_send_notify_* routines -> they are not needed
4182 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Fixed memory leak in silc_encode_pem_file in the file
4185 lib/silcutil/silcutil.c.
4187 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Check minor version as well in the SKE. Affected files are
4190 silcd/protocol.c and lib/silcclient/protocol.c.
4192 * Added --identifier option to the server so that an identifier
4193 can be when creating the public key for the server. Affected
4194 file is silcd/silcd.c.
4196 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4197 lib/silccrypt/silcpkcs.c.
4199 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Register default ciphers and stuff when using -C option with
4202 the server. Affected file sildc/silcd.c.
4204 * Put back the servers public key filename format, it is better
4205 than the new one. For now, the client keys are saved with the
4206 new filename format. The affected file silc/client_ops.c.
4208 * Implemented the Cipher API for the rest of the ciphers that
4209 did not implement it or implemented it the wrong way.
4211 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Register default ciphers and stuff when using the -S option
4214 in the client. Affected file silc/silc.c. Same also when
4215 creating new key pair with -C option.
4217 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4219 * Fixed the silc_verify_public_key client operation function to
4220 save the public keys differently. The fingerprint is now
4221 used as filename and not the hostname. This way also the
4222 client keys are saved uniquely and not with hostnames. The
4223 affected file is silc/client_ops.c.
4225 * Trimmed the silc_hash_fingerprint function to remove extra
4226 whitespaces from the end of the fingerprint. The affected
4227 file is lib/silccrypt/silchash.c.
4231 * Added silc_cipher_register_default function to register all
4232 default ciphers. It can be used when configuration files
4233 does not exist and the application does not want any specific
4234 ciphers in any specific order.
4236 The SilcDList is now used as silc_cipher_list dynamically
4237 allocated cipher list. Removed the static list all together
4238 and now all ciphers must be allocated to the dynamic list.
4239 The silc_cipher_alloc routine was changed to check only the
4242 All silc_cipher_* routines that used to return int returns
4245 The affected files lib/silccrypt/silccrypt.[ch].
4247 * The same thing was done to silc_hash_* as for silc_cipher_*
4248 routines. Affected files lib/silccrypt/silchash.[ch].
4250 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4251 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4252 Added also silc_pkcs_[un]register[_default] functions.
4253 Removed the data_context from the PKCS API.
4255 * Added silc_hmac_register_default function to register default
4256 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4257 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4258 to unregister all hmacs at once.
4260 * Register the default ciphers, hash functions, PKCSs and HMACs
4261 if client's configuration file does not exist. The affected
4264 * The client did not load the hash functions from the SIM
4265 modules at all. Added support for this. Affected file is
4266 silc/clientconfig.c.
4268 * When decoding public key with silc_pkcs_public_key_decode, check
4269 the supported algorithm only if PKCS are registered. Affected
4270 file lib/silccrypt/silcpkcs.c. The same was done with the
4271 silc_pkcs_private_key_decode.
4273 * Fixed the SILC List routines to keep the list always in order.
4274 It used to change the list's order when traversing the list but
4275 not it preserves the order. Affected file lib/trq/silclist.h.
4277 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Added the client library to use the SilcSocketConnection's
4280 reference counter (by silc_socket_dup) to prevent the bug that
4281 the socket object may be freed underneath async operation.
4283 * The name resolv library checking fixes in the configure.in.pre.
4286 * Created new version of the protocol drafts for future
4287 development. The -03 drafts are the ones that will be changed
4288 in the trunk now and the -02 will remain as they are.
4290 * Send list of CUMODE notifys to the router when announcing
4291 the channel users to the router. Affected file silcd/server.c.
4292 If the router receiving channel founder CUMODE for a channel
4293 that already has channel founder it will send CUMODE notify
4294 to the sender to remove the channel founder rights from the
4295 announced client. Affected file silcd/packet_receive.c.
4297 * The CUMODE notify may now use Server ID as well as the entity
4298 who changes the mode. Updated protocool specs.
4300 * Updated INSTALL and README files.
4302 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * New web pages in the http://silc.pspt.fi. The pages was
4309 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Implemented the [DenyConnectin] config section in the server.
4312 Added silc_server_config_denied_conn to check whether incoming
4313 connection is denied. Affected file silcd/serverconfig.[ch].
4315 * Do not check the ports when checking the incoming configuration
4316 data if the port is 0, meaning any. Affected file is
4317 silcd/serverconfig.c.
4319 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Fixed buffer overflow in silc_string_compare in the file
4322 lib/silcutil/silcutil.c.
4324 * Fixed double free in silc_server_command_leave in the file
4327 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Fixed the version checking in the server. Affected file is
4332 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Fixed the configuration data fetching when accepting new
4335 connections in the server. Affected file silcd/server.c.
4337 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Added `sender_entry' argument to the function
4340 silc_server_packet_relay_to_channel so that we can check
4341 whether some destination actually belongs to the same route
4342 the sender belongs (ie, we must not resend the packet to the
4343 sender). Affected file silcd/packet_send.[ch].
4345 * Added `servername' field to the SilcClientEntry in the server
4346 to hold the name of the server where client is from. Affected
4347 file is silcd/idlist.h.
4349 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Moved the channel message encrypting in the router betwen
4352 router connections from silc_server_channel_message to the
4353 silc_server_packet_relay_to_channel since we want to check
4354 whether we have anybody channel before encrypting anything.
4355 Affected files silcd/packet_[receive/send].c.
4357 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4359 * Fixed the [AdminConnection] server config section to support
4360 multiple entries. Affected file silcd/serverconfig.c.
4362 * Added support into the server to check the validity of the
4363 incoming connection before executing any KE or authentication
4366 * The connection configuration is now saved to the KE and
4367 connection auth protocol contexts and not fetched anymore in
4368 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4370 * The local hosts listenning address and port is also resolved
4371 now when starting the server. We want to have the socket object
4372 to include the real address and port for the listener. Added
4373 new function silc_net_check_local_by_sock into the files
4374 lib/silcutil/silcnet.[ch].
4376 * Fixed a broadcast bug in server -> do not broadcast if we
4379 * Fixed a routing bug. Do not route broadcast packets ever.
4380 Broadcast packets must be processed always and not routed since
4381 they may be destined to some other host than yourself and thus
4382 would get routed without no good reason. Affected file is
4385 * Added function silc_server_config_is_primary_route to check
4386 whether primary router connection has been configured (a router
4387 configuration that we are initiating). If there is not, we
4388 will assume that there is only two routers in the SILC network
4389 and we will use the incoming router connection as our primary
4390 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4392 * Changed the order of the broadcasting. Broadcast _after_ the
4393 packet has been processed not before. Affected file is
4396 * Fixed a [ClientConnection] parsing bug. The port was never
4397 parsed correctly thus resulting to port 0. Affected file
4398 silcd/serverconfig.c.
4400 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4401 argument and did not set the broadcast packet flag. Affected
4402 file silcd/packet_send.c. Fixed same bug in the function
4403 silc_server_send_notify as well.
4405 * If we receive NEW_ID packet for our own ID in the server, ignore
4408 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4412 * Removed the nickname from the Private Message Payload.
4413 Updated the code and the protocol specs.
4415 * Updated protocol specs for submitting to the IETF.
4417 * Tweaked the Random Number Generator a bit. Affected file
4418 lib/silccrypt/silcrng.c. Exported a new function
4419 silc_rng_[global]_add_noise which can be used to add more
4422 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Do not parse packets with different timeout when protocol
4425 is active -> may cause problem with rekey. Affected file
4428 * When server receives signoff notify it must not create
4429 new channel key if the client is on any channels since the
4430 sender of the signoff notify will create it.
4432 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added printing of error messages during SKE protocol from the
4435 failure packet sent by server during SKE. Affected file
4438 * Removed the client's failure_callback handling with timeout
4439 and handle it immediately when received.
4441 * The SKE library returned wrong type in SUCCESS and FAILURE
4442 packets. They must be 32 bit MSB not 16 bit MSB.
4444 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Ok, rewrote the logic of the re-key and now it seems to work.
4447 I tested it on high traffic with frequent re-keys without
4448 problems. Added hmac_receive (and renamed hmac to hmac_send)
4449 in SilcClientConnection in lib/silcclient/client.h and
4450 in SilcIDListData in silcd/idlist.h. Also, removed the
4451 SilcPacketParserContext's cipher and hmac fields as they are
4452 not needed anymore and actually caused some problems when
4453 the ciphers and hmac's changed underneath the packet parser.
4455 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * If re-key protocol is active then process the incoming packets
4458 synchronously since we must assure that icoming packets encrypted
4459 with the old key is processed before the new keys is set to
4460 use. This is true other packets than for REKEY packets.
4461 Affected file silcd/server.c. The same was done to client library
4462 as well, affected file lib/silcclient/client.c.
4464 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Fixed bug in client and server to accept the force send if
4467 the packet is send from silc_[server/client]_packet_process
4468 function. Otherwise the packets are never delivered, oops.
4470 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Disable force sending of packets when REKEY protocol is active.
4473 We must assure that no packet is sent directly when rekey is
4474 performed. All packets must be sent through packet queue.
4475 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4476 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4477 function is silc_[server/client]_packet_send_real to check
4480 * Replaced the SIM paths from example config files to
4481 /usr/local/modules. Also, make install creates now
4482 /usr/local/silc/logs directory to hold all the SILC server
4485 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Made the configure.in.pre work on Solaris. Patch by salo.
4489 * Made all ciphers compatible with non-x86 machines. Defined
4490 CBC mode macros into lib/silccrypt/ciphers_def.h.
4492 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Fixed the make install.
4496 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * When MAC computation fails the silc_packet_decrypt returned 0
4499 even though it was supposed to return -1. Fixed this. The
4500 affected file is lib/silccore/silcpacket.c.
4502 * Do not replace the config files in /etc/silc (in make install)
4503 if they already exist. Affected file ./Makefile.am.
4505 * Do not send re-key packets immediately but through packet queue.
4506 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4508 * Changed silc_net_check_host_by_sock to return FALSE if the
4509 IP/DNS could not be resolved. Though, it returns the IP address
4510 now even if it could not resolve it (but returns also FALSE).
4511 Affected file lib/silcutil/silcnet.[ch].
4513 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Added silc_pkcs_decode_identifier to decode the public key's
4516 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4517 Added also silc_pkcs_free_identifier. Added also new context
4518 SilcPublicKeyIdentifier.
4520 * Added -S option to the silc client. It is used to dump the
4521 contents of the specified public key file.
4523 * Changed the PKCS api to return the public key length when
4524 setting the public key.
4526 * Fixed a fatal bug in the public and private key file loading.
4527 Affected file lib/silccrypt/silcpkcs.c.
4529 * Execute the packet parsing for client with zero (0) timeout
4530 if the protocol is active. Affected file silcd/server.c.
4532 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Made the key generation options to the silcd program. Added
4535 -C option, equivalent to client's option.
4537 * Added new [ServerKeys] config section to the server. It
4538 configures the server's public and private key.
4540 * Defined generic Public Key Payload into the protocol
4541 specification to send specific type of public keys and
4544 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4545 public key or certificate.
4547 * Implemented the GETKEY command to the server and to the
4548 client library and on user interface.
4550 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Made preliminary `make install' work.
4554 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Added SilcServerRekey context into silcd/idlist.h.
4558 * Added the PFS support as defined in the specification to the
4559 SKE protocol. Affected files lib/silcske/*.c.
4561 * Added `ske_group' field to the SilcServerRekey context to hold
4562 the number of the SKE group that is used with PFS in re-key.
4563 Affected file silcd/idlist.h.
4565 * Added PFS re-key support to the server. Affected file is
4568 * Added silc_protocol_cancel to cancel execution of the next
4569 state of the protocol. Affected file is
4570 lib/silccore/silcprotocol.[ch].
4572 * Added the re-key support with and without PFS to the client
4573 library. Re-key is performed once in an hour, by default.
4575 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4576 Added silc_client_rekey_callback and silc_client_rekey_final.
4577 Affected files are lib/silcclient/protocol.[ch] and
4578 lib/silcclient/client.[ch].
4580 * Removed the `hmac_key' and `hmac_key_len' fields from the
4581 SilcClientConnection structure; not needed. Affected file is
4582 lib/silcclient/client.h.
4586 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Do not ask whether user wants to use the negotiated private key
4589 for private messages, just use it. Affected file is
4590 silc/local_command.c.
4592 * Added `send_enc_key' and `enc_key_len' fields to the
4593 SilcIDListData structure since they are needed in the re-key
4594 phase. Affected file is silcd/idlist.[ch].
4596 * Implemented the simple re-key protocol into the server.
4597 Affected files silcd/server.c and silcd/protocol.[ch]. The
4598 re-key will be performed once in an hour, by default.
4600 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4601 Added silc_server_rekey, silc_server_rekey_callback and
4602 silc_server_rekey_final.
4604 * Removed Tunneled flag from the protocol. Updated the code
4605 and the specifications.
4607 * Adde `pfs' field to the SilcIDListData to indicate whether
4608 the PFS is to be performed in the re-key. Affected file is
4611 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4614 int64 of at least the xintXX size. If void * is less that 4
4615 bytes uint32 * will be used. Defined bool as boolean.
4617 * Changed _ALL_ unsigned long and unsigned int to uint32,
4618 unsgined short to uint16 in the source tree.
4620 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4621 not handle clients that has entry->data.registered == FALSE.
4622 They are not in the network anymore. Affected file is
4625 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4627 * Implemented the sending of the SERVER_SIGNOFF notify in the
4628 server. Affected file is silcd/server.c.
4630 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4631 Added also silc_notify_payload_encode_args into the
4632 lib/silccore/silcnotify.[ch].
4634 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4635 Affected file silcd/packet_receive.c.
4637 * Implemented the SERVER_SIGNOFF notify handling in the client
4638 library. Affected file lib/silcclient/client_notify.c. Also,
4639 implemnted the printing of the SERVER_SIGNOFF info to the
4640 application. Affected file silc/client_ops.c.
4642 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4643 if the deleting was successful. Affected file silcd/idlist.[ch].
4645 * Added support for public key authentication in the connection
4646 authentication protocol in the client library. Affected file
4647 lib/silcclient/protocol.c.
4649 * Changed the server's silc_idlist_get_clients_by_* interface
4650 to support already allocated array so that new entries may be
4651 added to pre-allocated array. Affected file silcd/idlist.[ch].
4652 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4653 and command replies.
4655 * All command reply functions in the server now calls the
4656 pending command callback even if error occured. This way the
4657 error will be delivered to the client as well. Affected files
4658 silcd/command.c and silcd/command_reply.c.
4660 * Fixed INFO command to return local server's info if no server
4661 was provided. Affected file lib/silcclient/command.c.
4663 * Removed RESTART command for good. Updated the code and the
4666 * Rewrote parts of the task system. It is a bit simpler now.
4667 Removed unsued task priorities. The affected files are
4668 lib/silcutil/silctask.[ch].
4670 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Moved the USERS printing from the library to the application.
4673 Affected files lib/silcclient/command.c and silc/client_ops.c.
4675 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Added channel key re-key support. The re-key is perfomed
4680 only by the router and is done once in an hour. Added `rekey'
4681 field to the SilcChannelEntry in the server. Affected files
4682 silcd/server.c and silcd/idlist.h.
4684 * Added silc_task_unregister_by_context into the file
4685 lib/silcutil/silctask.[ch].
4687 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Added SILC_UMODE_GONE mode to indicate when the client is not
4690 present in the SILC network. Added also support to the local
4691 command AWAY that will set this mode. Added support of showing
4692 "xxx is gone" in WHOIS command. The USERS command shows the
4693 gone status as well.
4695 * Fixed setting server and router operator privileges in the
4696 server's UMODE command. Affected file silcd/command.c.
4698 * Merged the SKE KE1 and KE2 payloads into one payload. The
4699 new KE payload is equivalent to the old KE2 payload.
4701 Cleaned up the SKE Start Payload parsing. It now uses the
4702 simple buffer unformatting to do the parsing. A lot faster
4705 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4706 to the SKE that is used to indicate whether both of the SKE
4707 parties should perform authentication. By default only the
4708 responder performs authentication. By setting this flag also
4709 the initiator must do authentication. By default it is unset
4710 since in normal SKE case, client to server connection, only
4711 the responder should do authentication. When doing SKE between
4712 two clients both should perform authentication. Updated the
4713 code and the protocol specs.
4715 * A little fix to IDENTIFY command in the server. Search the
4716 client first by hash not nickname. Affected file is
4719 * Fixed the silc_client_close_connection to support closing
4720 the client to client connections wihtout deleting too much
4721 data. Affected file lib/silcclient/client.c.
4723 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4724 are received if protocol used to be active but is not anymore
4725 the application would crash due to NULL pointer dereference.
4726 Affected files silcd/server.c and lib/silcclient/client.c.
4728 * Added `hash' field to the SilcClientConnection to include
4729 the hash function negotiated in the SKE protocol.
4731 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4732 to set the channel founder authentication data. A client can
4733 claim the founder rights later by providing the authentication
4734 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4735 This way the channel founder can regain the channel founder
4736 privileges even it is left the channel. This works only on
4737 local server and the client must be connected to the same
4738 server to be able to regain the founder rights. Updated the
4739 protocol specs accordingly.
4741 Added support to the CMODE command in the client to set the
4742 founder auth data. Read the README to see how to set it.
4744 Added support to the CUMODE command to claim the founder
4745 rights. Read the README to see how to do it.
4747 Added support for the founder authentication to the Channel
4748 Entry in the server. Affected file silcd/idlist.h.
4750 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4751 server's CMODE command. Affected file silcd/command.c.
4753 * Added the following new functions into lib/silccore/silcauth.[ch]:
4754 silc_auth_get_method and silc_auth_get_data.
4756 * The server now saves the remote hosts public key to the
4757 SilcIDListData pointer. Affected file silcd/protocol.c.
4759 * The normal server now does not remove the channel entry from
4760 the cache if the founder authentication data is set. It used
4761 to remove it if the founder was the last one on the channel on
4762 the server and left the channel. The auth data is saved and
4763 if the channel is re-joined later the old entry is used with
4764 the old auth data. Affected files silcd/command_reply.c and
4767 * Removed the `pkcs' field from the SilcIDListData structure
4768 in the server; it is not used. Affected file silcd/idlist.h.
4770 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Fixed packet processing on slow links. Partial packets were
4773 never re-processed because the incoming data buffer was cleared
4774 by the application. Application must not directly clear the
4775 sock->inbuf, the packet processing routines handle it. Fixed
4776 this in client library and in server.
4778 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Fixed the WHOIS and IDENTIFY send reply function to really
4781 check whether to send list or just one entry. Affected file
4784 * Cleaned up the LEAVE command's channel key distribution. The
4785 affected file silcd/command.c.
4787 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4788 can enforce the channel mode as well. In that case the ID
4789 includes the ID of the server. The code now enforces the
4790 mode change if the router have different mode than the server.
4792 * The notify client operation with CMODE_CHANGE notify can now
4793 return NULL client_entry pointer if the CMODE was not changed
4794 by client. Application must check for this.
4796 * Added <Server ID> argument to INFO command to support server
4797 info fetching by Server ID.
4799 * Added silc_server_announce_get_channel_users to get assembled
4800 packets of channel users of the specified channel. Affected
4801 file silcd/server.[ch].
4803 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4804 was freed underneath the ID Cache.
4806 * Re-announce clients when the server received CHANNEL_CHANGE
4807 notify from the router. Affected file silcd/packet_send.c.
4809 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4812 crashed since it did not handle the fact that there is no cipher
4813 called "3" and didn't check the error condition. Now fixed.
4815 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4816 flag. It can be used to send message requests.
4818 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Implemented the RESTART command in the client.
4822 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4823 notice type messages. Added notice printing to the user
4826 * The channel keys are not re-generated if the channel's mode
4827 is PRIVKEY, ie private key on the channel exists. Affected
4828 files silcd/server.c and silcd/command.c.
4830 * Fixed a little bug in channel message delivery when channel
4831 private keys are set in the server. Affected file is
4832 silcd/packet_send.c.
4834 * Changed the setting on channel->on_channel = TRUE from the
4835 silc_client_save_channel_key to the JOIN command reply. The
4836 key payload is not received if the private channel key is set.
4837 Affected file lib/silcclient/command_reply.c and the
4838 lib/silcclient/client_channel.c.
4840 * When the CMODE_CHANGE notify is sent and the channel private
4841 key mode is removed the channel key must be re-generated in
4842 other cells as well. Added this support for the router in the
4843 silcd/packet_receive.c.
4845 * Added new local command NOTICE to send notice message on
4846 channel. Affected file silc/local_command.[ch].
4848 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Added new local command ME to the client. It is used to send
4851 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4852 some action. Affected file silc/local_command.[ch].
4854 * Changed channel_message and private_message client operations
4855 to deliver the message flags to the application. Added also
4856 the `flags' arguments to the silc_client_send_channel_message
4857 and silc_client_send_private_message functions. Affected file
4860 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4862 * Redefined the Private Message Payload to support private message
4863 keys and to support the new private message flags. Updated
4864 the protocol specs. Flags makes it possible to have for example
4865 CTCP style messages.
4867 * Added new type SilcPrivateMessagePayload and defined an API
4868 for it in the lib/silcclient/silcprivate.[ch].
4870 * Tested private message private keys successfully. Tested the
4871 private message key set, unset and list commands with the new
4874 * Redefined the Channel Message Payload to include the channel
4875 message flags (equal with private message flags) to support
4876 for example CTCP style messages.
4878 * Defined some of the message (for channel and private message)
4879 flags. Updated the protocol specs and added the flags to the
4880 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4882 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4884 * Added SilcKeyAgreementStatus type to the key agreement routines
4885 to indicate the current status and error if one occured.
4886 The status types are defined in the lib/silcclient/silcapi.h.
4888 * Added new local command KEY that is used to set and unset private
4889 keys for channels, set and unset private keys for private messages
4890 with remote clients and to send key agreement requests and
4891 negotiate the key agreement protocol with remote client. The
4892 key agreement is supported only to negotiate private message keys,
4893 it currently cannot be used to negotiate private keys for channels,
4894 as it is not convenient for that purpose.
4896 * Fixed a minor pending callback setting bug in the function
4897 silc_client_get_client_by_id_resolve, now the function works.
4898 Affected file lib/silcclient/idlist.c.
4900 * Added function silc_net_get_local_port to get local bound
4901 port by socket. Added to lib/silcutil/silcnet.[ch].
4903 * Added `sockets' and `sockets_count' fields to the SilcClient
4904 object. They hold the sockets of the listenning sockets in
4905 the client. Listenning sockets may be for example the key
4906 agreement server. Affected file lib/silcclient/client.[ch].
4907 Added functions the silc_client_add_socket and the
4908 silc_client_del_socket. They are exported to the application
4911 * Added ~./silc/clientkeys to support other client's public keys.
4913 * Renamed verify_server_key client operation to verify_public_key
4914 and added one argument to indicate the type of the connection
4915 (server, client etc.).
4917 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Added silc_server_connection_auth_request to handle the
4920 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4921 silcd/packet_receive.[ch].
4923 * Added silc_server_send_connection_auth_request into the
4924 silcd/packet_send.c to send the connection auth request packet.
4926 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4929 * Fixed the public key authentication in responder side in the
4930 server. The `auth_data' pointer includes the SilcPublicKey
4931 not the path to the public key. Affected file silcd/protocol.c.
4933 * Implemented the public key authentication in the initiator side
4934 in the server. Affected file silcd/protocol.c.
4936 * Removed the [RedirectClient] config section from the server
4937 configuration. Is not needed and I don't want to implement it.
4939 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Cleaned up the CMODE command in the server. It now works
4942 correctly and supports all the modes defined in the protocol.
4943 Affected file is silcd/command.c.
4945 * Added `hmac_name' field to the SilcChannelEntry in the server
4946 to hold the default HMAC of the channel. It can be set when
4947 creating the channel (with JOIN command). Affected files
4950 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4951 type to indicate the change of the current cipher and hmac
4952 on the channel. Client can safely ignore the <cipher> argument
4953 (if it chooses to do so) since the CHANNEL_KEY packet will
4954 force the channel key change anyway. The <hmac> argument is
4955 important since the client is responsible of setting the new
4956 HMAC and the hmac key into use.
4958 * Fixed the CMODE command in the client library as well.
4960 * Tested CMODE command in router environment successfully.
4962 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Show the version of the remote client (or server) when connecting
4965 to the server. It is logged to the log file. Affected file
4966 is silcd/protocol.c.
4968 * Fixed the KILLED notify handling in the client library. The
4969 client must be removed from all channels when receiving the
4972 Also, do not remove the client entry when giving the KILL
4973 command but when the KILLED notify is received.
4975 * Removed silc_idlist_find_client_by_nickname from the server.
4976 Not needed anymore. Affected files silcd/idlist.[ch].
4978 * Implemented the CHANNEL_CHANGE notify type handling to the
4979 server. Affected file silcd/server.c.
4983 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added silc_server_send_notify_invite to send the INVITE
4986 notify between routers.
4988 * Implemented the INVITE command correctly to the server.
4990 * Implemented the INVITE notify type handling in the server.
4992 * Implemented the INVITE command to the client library and on the
4995 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Added function silc_server_get_client_resolve to find the
4998 client entry by ID from all ID lists and then resolve it
4999 (using WHOIS) if it cannot be found. Affected file is
5002 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Implemented the BAN command to the client library.
5006 * The JOIN command in the server now checks the invite list
5009 * Changed the silc_command_reply_payload_encode_va and the
5010 silc_command_payload_encode_va to support that if argument is
5011 NULL it ignores and checks the next argument. Affected file
5012 lib/silccore/silccommand.c.
5014 * Added silc_server_send_notify_ban to send the BAN notify
5015 type between routers.
5017 * Chaned the silc_notify_payload_encode to support that if
5018 argument is NULL it ignores and checks the next argument.
5019 Affected file lib/silccore/silcnotify.c.
5021 * Tested ban lists in router environment successfully.
5023 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Implemented BAN command to the server, in silcd/command.[ch].
5027 * Removed the BAN and INVITE_LIST modes from the CMODE command
5030 * Added function silc_string_match to regex match two strings.
5031 Affected files lib/silcutil/silcutil.[ch].
5033 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Redefined parts of the SilcChannelEntry in the server to support
5036 the new ban and invite lists.
5038 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Redefined the INVITE command. The same command can be used to
5041 invite individuals to the channel but also to manage the invite
5042 list of the channel (to add to and remove from the invite list).
5043 Updated the protocol specs.
5045 * Added new command SILC_COMMAND_BAN that can be used to manage
5046 the ban list of the channel. Updated the protocol specs.
5048 * Removed the channel modes: the SILC_CMODE_BAN and the
5049 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5050 in the CMODE command. The equivalent features are now available
5051 using INVITE and BAN commands. Updated the protocol specs.
5053 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5054 in the network about change in the current ban list. The notify
5055 type is not used by the client.
5057 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5058 support the invite lists.
5060 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Added new function silc_string_regexify that converts string
5063 including wildcard characters into regex string that can
5064 be used by the GNU regex library. Added into the file
5065 lib/silcutil/silcutil.[ch].
5067 Added silc_string_regex_combine to combine to regex strings
5068 into one so that they can be used as one regex string by
5069 the GNU regex library. Added into the file
5070 lib/silcutil/silcutil.[ch].
5072 Added silc_string_regex_match to match two strings. It returns
5073 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5075 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Imported GNU regex to the soruce tree into lib/contrib.
5078 Fixed some compiler warning from the regex.c.
5080 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Fixed MOTD command in the server to work in router environment.
5084 * Fixed the MOTD command in the client library to support
5085 the server argument in the command.
5087 * Added `nickname_len' argument to the silc_idlist_add_client
5088 in the server, as the `nickname' argument may be binary data
5091 * Added silc_idlist_get_channels to return all channels from
5094 * Implemented LIST command to the server. Affected file is
5097 * Implemented the LIST command to the client library and on the
5100 * Added [<user count>] argument to the LIST command reply.
5101 With private channels the user count is not shown.
5103 * Updated TODO and README.
5105 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * The client entry's data.registered must be TRUE even with
5108 global client entry on global client list. The data.registered
5109 is used to check whether the client is anymore in the network,
5110 for example with WHOWAS command so it must be valid.
5112 * Fixed the WHOWAS command in the server. It now actually works
5113 in router environment. Added function into silcd/command_reply.c
5114 silc_server_command_reply_whowas_save.
5116 * Added silc_idlist_purge function to the silcd/idlist.c
5117 to periodically purge the ID Cache.
5119 * Fixed INFO command in the server. It works now in router
5120 environment. Added <server name> argument to the INFO command
5121 reply. Updated the protocol specs.
5123 * Fixed minor bug in silc_idcache_purge to not purge if the
5124 expire value is zero.
5126 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5127 they were buggy because of the WHOWAS information.
5129 * Fixed local command MSG to handle the async resolving of
5130 the remote client properly. It used to fail the first MSG.
5131 Affected file silc/local_command.c.
5133 * Added `data_len' field to SilcIDCache context.
5135 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Update TODO. Todo in commands in the server.
5139 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5142 used by routers as broadcast packet to inform other routers
5143 about the changed user mode.
5145 Implemented the notify handling in the server. Affected file is
5146 silcd/packet_receive.c. Added the function
5147 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5149 * Added new generic Channel Payload and deprecated the New Channel
5150 Payload. The New Channel Payload is now the generic Channel
5153 * Added new argument `mode' to the silc_server_send_new_channel
5154 as it is required in the Channel Payload now.
5156 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5157 and created a new and real SilChannelPayload to represent the
5158 new generic Channel Payload. Implemented the encode/decode
5159 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5161 * Added silc_server_get_client_channel_list to return the list
5162 of channels the client has joined for WHOIS command reply.
5163 Affected file silcd/server.[ch].
5165 * Implemented the channel list sending in the WHOIS command reply
5166 in server and in the client.
5168 Implemented the channel list displaying on the user interface
5169 as well. Affected file silc/client_ops.c.
5171 * Added silc_channel_payload_parse_list to parse list of Channel
5172 Payloads. It returns SilcDList list of SilcChannelPayloads.
5173 Client for example can use this function to parse the list of
5174 channels it receives in the WHOIS command reply. The caller
5175 must free the list by calling silc_channel_payload_list_free.
5176 Affected files lib/silccore/silcchannel.[ch].
5178 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Added one new argument <user mode> to the WHOIS command reply
5181 to return the mode of the user in SILC. Updated the protocol
5184 Implemented it to the server and client.
5186 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Fixed the mode printing on the user interface on joining.
5189 Affected file silc/client_ops.c.
5191 * Implemented the UMODE command and user modes in general to the
5192 client library and to the user interface.
5194 * Implemented the UMODE command to the server.
5196 * The server now sends UNKNOWN_COMMAND error status if client sends
5197 unknown command. Affected file silcd/command.c.
5199 * All server commands now handle the command identifier the right
5200 way when sending the command reply to the client. The client can
5201 use to identify the command replies with the identifier.
5203 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * Added silc_server_get_client_route to resolve the route to
5206 the client indicated by the client ID. Affected file is
5209 * Added silc_server_relay_packet as general function to relay
5210 packet to arbitrary destination. This deprecates functions
5211 like _send_private_message_key, _relay_notify etc. Affected
5212 file is silcd/packet_send.[ch].
5214 Removed silc_server_send_key_agreement,
5215 silc_server_send_private_message_key and
5216 silc_server_packet_relay_notify functions from the file
5217 silcd/packet_send.[ch].
5221 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5222 server. Affected file silcd/packet_receive.[ch].
5224 * Implemented the KILL command to the client. Implemented the
5225 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5226 Affected files lib/silcclient/command[_reply].c and
5227 lib/silcclient/client_notify.c. Implemented the KILL notify
5228 printing in the user inteface.
5230 * Fixed a lot silc_parse_nick memory leaks from the client
5231 library in the file lib/silcclient/command.c.
5233 * Changed the silc_server_send_notify_on_channels's `sender'
5234 argument from SilcSocketConnection to SilcClientEntry to
5235 check the sender as entry and not as connection object and not
5236 to send to the client provided as argument. The affected file
5237 is silcd/packet_send.[ch].
5239 * The notify packets that are destined directly to the client used
5240 to not to be processed by the server. Now changed that and the
5241 server processes all notify packets. After relaying the packet
5242 to the client the notify packet is processed in the server.
5244 * The silc_server_free_client_data now checks whether there is
5245 pending outgoing traffic for the client and purges the data to
5246 the network before removing the client entry.
5248 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5251 an client is killed from the SILC Network. Updated the protocol
5254 Added new function silc_server_send_notify_killed to the
5255 silcd/packet_send.[ch].
5257 * Added function silc_server_packet_relay_notify to relay notify
5258 packets that are destined directly to a client. In this case
5259 the server does not process the notify packets but merely relays
5260 it to the client. Affected file silcd/packet_send.[ch].
5262 Added also silc_server_packet_process_relay_notify to check
5263 whereto relay the notify. Affected file is
5264 silcd/packet_receive.[ch].
5266 * Implemented the KILL command to the server.
5270 * Added the backup schema desgined last fall to the protocol
5271 specs for everyone to see. The specification is in the
5272 *-spec-xx.txt draft and the packet type definitions for the
5273 backup routers is in *-pp-xx.txt draft. Thusly, added also
5274 new packet type SILC_PACKET_CELL_ROUTERS.
5276 * A big security problem in the implementation discovered. The
5277 signoff of an client did not cause new channel key generation
5278 which it of course should've done. The channel keys must be
5279 always re-generated when client leaves (or signoffs) the channel.
5280 The silc_server_remove_from_channels funtion now handles
5281 the channel key re-generation.
5283 * Added `sender' argument to the silc_server_send_notify_on_channels
5284 to not to send the client provided as argument. Affected file
5285 silcd/packet_send.[ch].
5287 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Implemented OPER and SILCOPER commands into the server and
5292 * Added silc_auth_verify and silc_auth_verify_data to verify
5293 the authentication directly from the authentication payload.
5294 It supports verifying both passphrase and public key based
5295 authentication. Affected file lib/silccore/silcauth.[ch].
5297 * Added `hash' field to the SilcIDListData structure. It is the
5298 hash negotiated in the SKE protocol. Affected file is
5301 * Slight redesigning of the SilcAuthPayload handling routines.
5302 Do not send SilcPKCS but SilcPublicKey as argument.
5304 * Implemented the public key authentication support to the
5305 serverconfig. The public key is loaded from the provided path
5306 and saved as authentication data to void * pointer. Thus,
5307 changed the unsigned char *auth_data to void *auth_data;
5309 * Fixed SHUTDOWN command to send the reply before the server
5310 is shutdown. :) Affected file silcd/command.c.
5312 * Fixed fatal bug in CONNECT command. The hostname was invalid
5313 memory and server crashed. Affected file silcd/command.c.
5315 * Fixed fatal bug in CLOSE command. The server_entry became
5316 invalid but was referenced later in the command. Affected file
5319 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Fixed fatal bug in failure packet handling. Server ignored
5322 the failure and thus crashed when it came.
5326 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5329 that the command may be executed only once in (about) 2 seconds.
5330 The old SILC_CF_LAG flag is same but allows command bursts up
5331 to five before limiting.
5333 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5334 server code. Various commands now includes the CF_LAG_STRICT
5335 flag to disallow any kind of miss-use of the command.
5337 * Fixed the silc_buffer_unformat to not to allocate any data
5338 if the length of the data is zero. It used to allocate the
5339 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5341 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Changed the format of AdminConnection configuration section
5344 in the server. Added username of the admin to the format.
5345 Affected files silcd/serverconfig.[ch].
5347 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5348 to return admin configuration data by host, username and/or
5351 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Implemented WHOWAS command to the server. Added the functions:
5355 silc_server_command_whowas_parse,
5356 silc_server_command_whowas_send_reply,
5357 silc_server_command_whowas_from_client and
5358 silc_server_command_whowas_from_server
5360 * Added <Client ID> argument to the WHOWAS command reply. Updated
5361 the protocol specs accordingly.
5363 * Implemented WHOWAS command and command_reply to the client
5366 Implemented the WHOWAS printing on the user interface.
5368 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Added new argument to the WHOWAS command reply, the real name.
5371 It is an optional argument. Updated the protocol specs.
5373 * Added SilcIDCacheDestructor callback that is registered when
5374 the SilcIDCache is allocated. The callback is called when
5375 an cache entry in the ID Cache expires, or is purged from the
5376 cache. Added into lib/silccore/idcache.[ch].
5378 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5379 to destruct the client entries when the cache entry expires.
5380 Other ID Cache's in server and in the client library ignores
5383 * If the ID Cache entry's `expire' field is zero then the entry
5384 never expires. Added boolean `expire' argument to the
5385 silc_idcache_add function in the lib/silccore/idcache.[ch].
5386 If it is TRUE the default expiry value is used.
5388 * Added silc_server_free_client_data_timeout that is registered
5389 when client disconnects. By default for 5 minutes we preserve
5390 the client entry for history - for WHOWAS command.
5392 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Added support to the server to enforce that commands are not
5395 executed more than once in 2 seconds. If server receives
5396 commands from client more frequently, timeout is registered
5397 to process the commands. Affected file silcd/command.c.
5398 Added new function silc_server_command_process_timeout.
5400 * Changed NICK_NOTIFY handling in client library to check that
5401 if the client's nickname was changed, so there is no need to
5402 resolve anything from the server.
5404 * Removed error printing from the WHOIS and IDENTIFY commands.
5405 If error occurs then it is ignored silently in the client library.
5406 The application, however, may map the received error to
5407 human readable error string. The application currently maps
5408 the NO_SUCH_NICKNAME error to string.
5410 * Made the command status message public to the application. Moved
5411 them from lib/silcclient/command_reply.c to
5412 lib/silcclient/command_reply.h. The application can map the
5413 received command status to the string with the
5414 silc_client_command_status_message function.
5416 * Added check to the server to check that client's ID is same
5417 as the Source ID in the packet the client sent. They must
5420 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Added dist-bzip hook to the Makefile.am to make bzip2
5423 compressed distributions.
5425 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Server now enforces the maximum length for the nickname and
5428 the channel as protocol specification dictates. 128 bytes for
5429 nickname and 256 bytes for channel name.
5431 * Moved the WHOIS printing to the application. The client libary
5432 does not print out the WHOIS information anymore, the application
5433 must do it. Renamed silc_client_command_reply_whois_print to
5434 the silc_client_command_reply_whois_save.
5436 The client's idle time is also sent to the application now, and
5437 the idle is shown on screen.
5439 * Added silc_client_command_reply_identify_save to save the
5440 received IDENTIFY entries.
5442 * Do not check for channel private keys in message sending and
5443 reception if the channel does not have the PRIVKEY mode set.
5444 Affected file lib/silclient/client_channel.c.
5446 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5449 just surfaced after chaning the JOIN procedure.
5451 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Added silc_client_get_clients_by_list to get client entries
5454 from Client ID list, that is returned for example by JOIN
5455 and USERS command replies. The application should use this
5456 function for example when JOIN command reply is received to
5457 resolve the clients already on the channel (library does not
5458 do that anymore as USERS command reply is not used in the JOIN
5459 procedure anymore). Affected files lib/silcclient/silcapi.h and
5460 lib/silcclient/idlist.c.
5462 * JOIN command reply and USERS command reply returns now SilcBuffer
5463 pointers instead of unsigned char pointers when returning
5464 the client list and mode list.
5466 * Added <Client ID> argument to the JOIN command reply, mainly
5467 for the server to identify for which client the command was
5468 originally sent. Updated protocol specs accordingly.
5470 * Added SilcDlist private_key pointer to the SilcChannelEntry
5471 in the client to support the channel private keys. Affected
5472 file is lib/silcclient/idlist.h.
5474 * Added SilcChannelPrivateKey argument to the function
5475 silc_client_send_channel_message so that application can choose
5476 to use specific private ke if it wants to. If it is not provided,
5477 the normal channel key is used, unless private keys are set.
5478 In this case the first (key that was added first) is used
5479 as the encryption key.
5481 * Implemented the support for channel private key handling.
5482 Implemented the following functions:
5484 silc_client_add_channel_private_key,
5485 silc_client_del_channel_private_keys,
5486 silc_client_del_channel_private_key,
5487 silc_client_list_channel_private_keys and
5488 silc_client_free_channel_private_keys
5490 Affected file lib/silcclient/client_channel.c.
5492 * Added the support for the private keys in the channel message
5493 sending and encryption and in the message reception and
5494 decryption. Affected funtions are
5495 silc_client_send_channel_message and silc_client_channel_message.
5497 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Added SKE's key verify callback to the client library's
5500 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5502 * Removed the statement that server (or router) must send USERS
5503 command reply when joining to the channel so that the client
5504 knows who are on the channel. Instead, the client list and
5505 client's mode list is now sent in the JOIN command reply to the
5506 client who joined channel. This is better solution.
5508 * Added function silc_server_get_users_on_channel and function
5509 silc_server_save_users_on_channel to the silcd/server.[ch].
5511 * Removed function silc_server_command_send_users from the
5514 * Do not show topic on the client library anymore. The topic is
5515 sent in the command reply notify to the application and the
5516 application must show the topic now.
5518 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Added client searching by nickname hash into the IDENTIFY and
5521 WHOIS commands in the server as they were clearly missing from
5522 them. Affected file is silcd/command.c.
5524 * Fixed a bug in private message receiving in the client library.
5525 The remote ID was freed and it wasn't supposed, now it is
5528 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Minor fix to the channel payload; allocate the data area, as it
5531 needs to be of specific length.
5533 * If the key agreement port is zero then the operating
5534 system will define the bound port. Affected files are
5535 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5537 * Added new function silc_channel_payload_decrypt into the file
5538 lib/silccore/silcchannel.[ch].
5540 * Moved the channel message etc, check from silc_packet_decrypt
5541 to applications. The library calls now a generic
5542 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5543 when the packet is either normal or special. This was done to
5544 allow more wide range of checking that was not allowed when
5545 the code was in library. Now applications can do virtually any
5546 checks to the packet and return to the library the decision how
5547 the packet should be processed. Affected files are
5548 lib/silccore/silcpacket.[ch].
5550 Added silc_server_packet_decrypt_check to the server and
5551 silc_client_packet_decrypt_check to the client library.
5553 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5554 to send with specified source and destination information.
5556 * Channel message delivery between routers was broken after the
5557 channel key distribution was fixed earlier. The channel key
5558 was used be to distributed to other routers as well which is not
5559 allowed by the protocol. Now this is fixed and channel keys
5560 really are cell specific and the channel message delivery between
5561 routers comply with the protocol specification.
5563 * Fixed various commands in server to check also the global list
5564 for the channel entry and not just the local list. The affected
5565 file silcd/command.c.
5567 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Added assert()s to buffer formatting and unformatting routines
5570 to assert (if --enable-debug) when error occurs. Affected
5571 file: lib/silcutil/silcbuffmt.c.
5573 * Changed to auto-reconnect to check whether the remote host is
5574 router and register the re-connect timeout if it is. It used
5575 to check that whether we are normal server, but router must do
5576 auto-reconnect with another router as well. Affected file
5579 * Removed the [<key len>] option from CMODE command as the cipher
5580 name decides the key length, nowadays. See the defined ciphers
5581 from the protocol specification.
5583 * Added [<hmac>] option to the CMODE command to define the HMAC
5584 for the channel. Added SILC_CMODE_HMAC channel mode.
5586 * Added [<hmac>] option for the JOIN command so that user can
5587 select which HMAC is used to compute the MACs of the channel
5590 * Added Hmac field to the Channel Message Payload. The integrity
5591 of plaintext channel messages are now protected by computing
5592 MAC of the message and attaching the MAC to the payload. The
5593 MAC is encrypted. Now, it is clear that this causes some
5594 overhead to the size of the packet but rationale for this is that
5595 now the receiver can verify whether the channel message decrypted
5596 correctly and also when private keys are set for the channel the
5597 receiver can decrypt the packet with several keys and check from
5598 the MAC which key decrypted the message correctly.
5600 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5601 lib/silccrypt/silccipher.[ch].
5603 * Added silc_hash_len to return the digest length into the
5604 lib/silcrypt/silchash.[ch].
5606 * Rewrote parts of Silc Channel Payload interface in the
5607 lib/silccore/silcchannel.[ch]. The encode function now also
5608 encrypts the packet and parse function decrypts it.
5610 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Fixed a minor formatting bug in the SKE's key material processing.
5613 It actually might have processed the keys wrong way resulting
5616 * Redefined the mandatory HMAC algorithms and added new algorithms.
5617 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5618 and hmac-md5 truncated to 96 bits. The mandatory is now
5619 hmac-sha1-96. Rest are optional (including the one that used
5620 to be mandatory). Rationale for this is that the truncated HMAC
5621 length is sufficient from security point of view and can actually
5622 make the attack against the HMAC harder. Also, the truncated
5623 HMAC causes less overhead to the packets. See the RFC2104 for
5626 * Added new [hmac] configuration section. The SKE used to use
5627 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5628 is of course wrong. The official names that must be proposed in
5629 the SKE are the ones defined in the protocol specification
5630 (hmac-sha1-96 for example). The user can configure any hmac
5631 using any hash function configured in the [hash] section. At
5632 least, the mandatory must be configured.
5634 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5636 * Added HMAC list to the SKE proposal list. It has now both
5637 hash algorithm list and HMAC list. This makes the protocol
5638 incompatible with previous versions. The SKE now seems to work
5639 the way it is supposed to work, for the first time actually.
5641 * Defined plain Hash algorithms to the protocol specification.
5644 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Implemented support for key agreement packets into the server.
5647 Added functions silc_server_key_agreement and
5648 silc_server_send_key_agreement. Other than these functions,
5649 server has nothing to do with this packet.
5651 * Added support for private message key packets into the server.
5652 Added functions silc_server_private_message_key and
5653 silc_server_send_private_message_key.
5657 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5658 called in the protocol's final callback instead in the END
5659 protocol state. This makes a little more sense and in the same
5660 time in client we can use the same protocol routines for normal
5661 key exchange and to key agreement packet handling as well.
5663 * Added to both client's and server's KE protocol context the
5664 SilcSKEKeyMaterial pointer to save the key material. We will
5665 bring the key material to the protocol's final callback by doing
5666 this. The final callback must free the key material.
5668 * Added SKE's packet_send callback into client's KE protocol
5669 context so that the caller can choose what packet sending function
5670 is used. This way we can use different packet sending when
5671 doing normal SKE when doing key agreement packet handling (in
5672 the key agreement packet handling we do not want to encrypt
5675 * Implemented the responder side of the key agreement routines
5676 in the client. The client can now bind to specified port and
5677 accept incoming key negotiation. The key material is passed
5678 to the application after the protocol is over.
5680 * Implemented the processing of incoming Key Agreement packet
5681 in the client. Added function silc_client_key_agreement to
5684 * Implemented the intiator side of the key agreement routines
5685 in the client. The client can now initiate key agreement with
5686 another remote client. The key material is passed to the
5687 application after the protocol is over.
5689 * Created client_keyagr.c to include all the key agreement
5692 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5693 SILC_TASK_CALLBACK except that it is not static.
5695 * Created client_notify.c and moved the Notify packet handling
5696 from the client.[ch] into that file.
5698 * Created client_prvmsg.c and moved all private message and
5699 private message key routines from the client.[ch] into that file.
5701 * Create client_channel.c and moved all channel message and
5702 channel private key routines from the client.[ch] into that file.
5704 * Changed silc_client_get_client_by_id_resolve to resolve with
5705 WHOIS command instead of IDENTIFY command, in the file
5706 lib/silclient/idlist.c.
5708 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Implemented the SKE's responder side to the Client library.
5712 * When FAILURE is received to the protocol do not trust it
5713 blindly. Register a timeout to wait whether the remote closes
5714 the connection as it should do it, only after that process the
5715 actual failure. This was changed to both client and server.
5717 * Added client_internal.h to include some of the structures
5718 there instead of client.h in lib/silcclient/.
5720 * Added function silc_task_unregister_by_callback to unregister
5721 timeouts by the callback function.
5723 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Some "Incomplete WHOIS info" errors has been appearing on the
5726 log files. Took away the entry->userinfo check from WHOIS
5727 reply sending. The entry->userinfo is now " " if client did not
5728 provide one. I thought this was fixed earlier but something
5729 is wrong still. Let's see if the error still appears.
5731 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Fixed a minor bug in the login when the channel key is
5734 re-generated in the server. It used to generate the key in
5735 wrong order and thus caused problems in the channel traffic.
5737 * Fixed a minor bug in channel key distsribution after
5738 KICK command. The key was not sent to the router even though
5741 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added silc_ske_process_key_material_data as generic routine
5744 to process any key material as the SILC protocol dictates. The
5745 function is used by the actual SKE library but can be used by
5746 applications as well. This relates to the private message keys
5747 and the channel private keys since they must be processed the
5748 same way the normal SILC session keys. The protocol dictates
5749 this. Affected files: lib/silcske/silcske.[ch].
5751 Added also silc_ske_free_key_material to free the
5752 SilcSKEKeyMaterial structure.
5754 * Defined silc_cipher_set_key function to set the key for
5755 cipher without using the object's method function. The affected
5756 files: lib/silccrypt/silccipher.[ch].
5758 * Implemented silc silc_client_add_private_message_key,
5759 silc_client_add_private_message_key_ske,
5760 silc_client_del_private_message_key,
5761 silc_client_list_private_message_keys and
5762 silc_client_free_private_message_keys functions in the
5765 Added functions silc_client_send_private_message_key to send
5766 the Private Message Key payload and silc_client_private_message_key
5767 to handle incoming Private Message Key payload.
5769 * Added Cipher field to the Private Message Key payload to set
5770 the cipher to be used. If ignored, the default cipher defined
5771 in the SILC protocol (aes-256-cbc) is used.
5773 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Removed lib/silcclient/ops.h file.
5777 Redefined parts of the SILC Client Library API. Created new
5778 file silcapi.h that deprecates the ops.h file and defines the
5779 published Client Library API. Defined also private message key
5780 API and channel private key API into the file.
5782 This is the file that the application must include from the
5783 SILC Client Library. Other files need not be included by
5784 the application anymore.
5786 * Added new key_agreement client operation callback and also
5787 defined the Key Agreement library API for the application.
5789 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5792 is used by clients to request key negotiation between another
5793 client in the SILC network. If the negotiation is started it
5794 is performed using the SKE protocol. The result of the
5795 negotiation, the secret key material, can be used for example
5796 as private message key.
5798 Implemented the Key Agreement payload into the files
5799 lib/silccore/silauth.[ch].
5801 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Redefined ciphers for the SILC protocol. Added some new ciphers
5804 and defined the key lengths for the algorithms. Changed the
5805 code accordingly. The default key length is now 256 bits.
5807 * Fixed SKE key distribution function silc_ske_process_key_material
5808 when the key length is more than 128 bits. The default key
5809 length in SILC is now 256 bits.
5811 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5812 to indicate unsupported algorithm.
5814 * Renamed rijndael.c to aes.c and all functions as well.
5816 * Fixed a long standing channel key setting bug in client library.
5817 Weird that it has never surfaced before.
5819 * Fixed bug in channel deletion. If the entire channel is removed
5820 then it must also delete the references of the channel entry
5821 from the client's channel list as the client's channel entry and
5822 the channel's client entry share same memory.
5824 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Implemented CONNECT and SHUTDOWN commands in the client.
5828 * Implemented CLOSE command to the client.
5830 * Added the function silc_idlist_find_server_by_name into the
5831 files silcd/idlist.[ch].
5833 Added the function silc_idlist_find_server_by_conn into the
5834 files silcd/idlist.[ch].
5836 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * DIE command was renamed to SHUTDOWN. Updated the both code
5841 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5842 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5844 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5847 * Added function silc_server_create_connection function to create
5848 connection to remote router. My server implementation actually
5849 does not allow router to connect to normal server (it expects
5850 that normal server always initiates the connection to the router)
5851 so the CONNECT command is only good for connecting to another
5854 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5857 or some other client was kicked from the channel.
5859 Implemented the handling of the notify type to both client
5862 Implemented silc_server_send_notify_kicked to send the KICKED
5863 notify. It is used to send it to the server's primary router.
5865 * Implemented the KICK command into server and client.
5867 * Added `query' argument to the silc_idlist_get_client function
5868 to indicate whether to query the client from server or not if
5871 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5872 to indicate that the client is not channel founder.
5876 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Removed the rng context from SilcPacketContext structure and
5879 changed that the packet routine uses the Global RNG API.
5881 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added support for quit message that client can "leave" on the
5884 channel when it quits the SILC. It is ditributed inside the
5885 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5887 Added silc_server_free_client_data that will take the
5888 signoff message as argument.
5890 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5892 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Updated parts of the protocol specification to keep it up
5897 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5900 payloads in one packet.
5902 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5903 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5904 use now the new List flag.
5906 * Also deprecated the following packet types: REPLACE_ID,
5907 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5909 * Added list support for Notify packet in server.
5911 * Added silc_server_send_notify_channel_change to send the
5912 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5913 the silc_server_send_replace_id.
5915 * Added silc_server_send_notify_nick_change to send the
5916 NICK_CHANGE notify type. Deprecates the function
5917 silc_server_send_replace_id.
5919 * Added silc_server_send_notify_join to send the JOIN notify type.
5920 Deprecates the function silc_server_send_new_channel_user.
5922 * Added silc_server_send_notify_leave to send LEAVE notify type.
5923 Deprecates the function silc_server_send_remove_channel_user.
5925 * Added silc_server_send_notify_cmode and
5926 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5927 types. Deprecates the silc_server_send_set_mode function.
5929 * Added SERVER_SIGNOFF notify type to indicate that server has
5930 quit. This means that all clients on the channel from that
5931 server will drop. This can be also used when netsplit happens.
5933 Deprecated REMOVE_ID packet type since it is not needed anymore
5936 Added silc_server_send_notify_server_signoff to send the
5937 SERVER_SIGNOFF notify type. Deprecates the function
5938 silc_server_send_remove_id.
5940 Added also silc_server_send_notify_signoff to send the
5941 SIGNOFF notify type.
5943 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5944 SILC protocol from this day on. Changed the protocol
5945 specification as well.
5947 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5948 notify type. It is used between routers to notify about
5949 topic changes on a channel.
5951 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5954 * Partly updated the protocol specification to comply with the
5955 changes now made. It is still though a bit outdated.
5957 * The JOIN notify type now takes one extra argument <Channel ID>.
5958 The packet used to be destined to the channel but now the
5959 JOIN type may be sent as list thus it is impossible to
5960 destine it to any specific channel. By adding this argument
5961 it is again possible.
5963 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Added CREDITS file. The CHANGES and CREDITS file will appear
5966 in the distribution as well.
5968 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5971 types in the server's silcd/packet_receive.c.
5973 * Implemented CMODE and CUMODE to work in router environment.
5975 * Fixed minor encoding and decoding buglet from the
5976 lib/silccore/silcmode.c.
5978 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5981 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5983 * Changed all SilcConfigServer* and silc_config_server* to
5984 SilcServerConfig* and silc_server_config*, respectively.
5987 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Associated the ID (client or server ID) to the Authentication
5990 Payload to avoid any possibility of forging. Updated the
5991 protocol specification and the code accordingly.
5993 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * The RSA key length is now save to the RsaKey context in the
5996 key generation process in lib/silccrypt/rsa.c. The key length
5997 is now used to figure out the maximum size of the block allowed
5998 to be encrypted/signed.
6000 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6001 is equivalent to the silc_mp_mp2bin but does not allocate any
6004 * Changed silc_mp_mp2bin API to take length argument. If it is
6005 non-zero then the buffer is allocated that large. If zero, then
6006 the size is approximated using silc_mp_sizeinbase, which however
6009 * Created Global RNG API which is global RNG that application can
6010 initialize. After initializing, any routine anywhere in the
6011 code (including library) can use RNG without allocating a new
6012 RNG object. This was done to allow this sort of use of the
6013 RNG in code that has no chance to allocate RNG object. All
6014 applications currently allocate this and many routines in the
6015 library use this. Affected file lib/silccrypt/silcrng.[ch].
6017 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6018 it to use the Global RNG API.
6020 * Defined Authentication Payload into protocol specification that
6021 is used during SILC session to authenticate entities. It is
6022 used for example by client to authenticate itself to the server
6023 to obtain server operator privileges.
6025 Implemented this payload into the lib/silccore/silcauth.[ch].
6026 Implemented also routines for public key based authentication
6027 as the new protocol specification dictates.
6029 Moved definitions of different authentication methods from
6030 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6032 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6033 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6034 silc_pkcs_verify_with_hash functions into the file
6035 lib/silccrypt/silcpkcs.[ch].
6037 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * The client entry's userinfo pointer must be always valid.
6040 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6041 will fail since it requires the userinfo. Now, the userinfo
6042 is allocated as "" if actual userinfo does not exist. Actually,
6043 it must exist and it is totally Ok to drop client connections
6044 that does not announce the userinfo. However, we will make
6045 this workaround for now.
6047 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6048 to return the remote port by socket.
6050 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6053 SILC_SERVER_PENDING_EXEC and added an new macro
6054 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6055 data or when error occurs while processing the pending command.
6057 Added new argument `destructor' into silc_server_command_pending
6058 and to the SilcServerCommandPending object. This destructor is
6059 now called after calling the pending callback or if error occurs
6060 immediately. If error occurs the actual pending callback won't
6061 be called at all - only the destructor. The destructor may be
6062 NULL if destructor is not needed.
6064 All this applies for client library code as well. Similar
6065 changes were made there as well for the pending commands.
6067 In the client, the application must now allocate the
6068 SilcClientCommandContext with the silc_client_command_alloc
6071 * Added reference counter to the SilcServerCommandContext. Added
6072 function silc_server_command_alloc and silc_server_command_dup
6075 Same type of functions added to the client library for the same
6078 * Removed the cmd_ident from IDListData away since it is now
6079 global for all connections. It is the command identifier used
6080 in command sending and with pending commands. The affected file
6083 * Added reference counter to the SilcSocketConnection objecet to
6084 indicate the usage count of the object. The object won't be
6085 freed untill the reference counter hits zero. Currently only
6086 server uses this, and client ignores it. The client must be
6087 set to use this too later. The affected files are
6088 lib/silccore/silcsockconn.[ch]. Added also the function
6089 silc_socket_dup to increase the reference counter.
6091 This was mainly added because it is possible that the socket
6092 is removed underneath of pending command or other async
6093 operation. Now it won't be free'd and proper DISCONNECTING
6094 flags, etc. can be set to avoid sending data to connection that
6095 is not valid anymore.
6097 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6098 the connection. After that it sets SILC_SET_DISCONNECTED.
6099 It is, however, possible that the socket data is not still freed.
6100 The silc_server_packet_process now checks that data is not
6101 read or written to connection that is DISCONNECTED. The socket
6102 get's freed when the reference counter hits zero.
6104 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Changed the client operation API: channel_message operation's
6107 `sender' is now the client entry of the sender, not the nickname
6108 and the `channel' is the channel entry, not the channel name.
6110 In the private_message operation the `sender' is now also the
6111 client entry of the sender not the nickname.
6113 Affected file is lib/silcclient/ops.h and all applications
6114 using the client operations.
6116 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Moved the calling of ops->connect() from connect_to_server_final
6119 into receive_new_id functin since that is the point when the
6120 client is actually allowed to send traffic to network. The
6121 affected file is lib/silcclient/client.c.
6123 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6126 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6127 (if needs broadcasting) instead of broadcasting the packets one
6128 by one which would make a burst in the network traffic.
6130 * Added `broadcast' argument to the functions in silcd/server.[ch]
6131 silc_server_create_new_channel[_with_id] to indicate whether
6132 to send New Channel packet to primary router.
6134 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Added new function into the silcd/server.[ch] files:
6137 silc_server_create_new_channel_with_id to create new channel with
6138 already existing Channel ID.
6140 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6141 lib/silccore/silcpacket.h. This packet is used t send list of
6142 Set Mode payloads inside one packet. Server uses this to set
6143 the modes for the channels and clients on those channels, that it
6144 announced to the router when it connected to it. The protocol
6145 specification has been updated accordingly.
6147 * The silc_server_new_channel did not handle the packet coming
6148 from normal server as it normally does not send that. However,
6149 when it announces its channels it does send it. Implemented
6150 the support for that.
6152 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6153 into the file lib/silccore/id.h.
6155 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Fixed memory leaks in the functions silc_idlist_del_client,
6158 silc_idlist_del_channel and silc_idlist_del_server in the file
6159 silcd/idlist.c. All of those leaked like a sieve.
6161 * Fixed some small memory leaks in the client's function
6162 silc_client_notify_by_server.
6164 * Added functions into silcd/server.c: silc_server_announce_clients,
6165 silc_server_announce_channels and silc_server_announce_server.
6166 These functions are used by normal and router server to announce
6167 to its primary router about clients, channels and servers (when
6168 router) that we own. This is done after we've connected to the
6171 These functions effectively implements the following packet types:
6172 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6173 and SILC_PACKET_NEW_ID_LIST.
6175 * Added new functions into the silcd/packet_receive.[ch]:
6176 silc_server_new_id_list, silc_server_new_channel_list and
6177 silc_server_new_channel_user_list to handle the incoming
6178 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6180 * Added support of changing Channel ID in the function
6181 silc_server_replace_id. If the server that announces a channel
6182 to the router already exists in the router (with same name but
6183 with different Channel ID), router is responsible to send
6184 Replace ID packet to the server and force the server to change
6185 the Channel ID to the one router has.
6187 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6188 client that the Channel ID has been changed by the router. The
6189 normal server sends this to the client. Client must start using
6190 the new Channel ID as the channel's ID.
6192 Implemented handling of this new type into lib/silcclient/client.c
6193 into the function silc_client_notify_by_server.
6195 * Added new function silc_idlist_replace_channel_id into the files
6196 silcd/idlist.[ch] to replace the Channel ID.
6198 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Call silc_server_command_identify_check always when processing
6201 the IDENTIFY command in silcd/command.c
6203 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6206 send keepalive packets. The packet can be sent by clients,
6207 servers and routers.
6209 Added function silc_socket_set_heartbeat into the file
6210 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6211 If not set, the heartbeat is not performed. The actual
6212 heartbeat is implemented in the low level socket connection
6213 library. However, application is responsible of actually
6216 Added silc_server_send_heartbeat to send the actual heartbeat
6217 packet into silcd/packet_send.[ch]. Server now performs
6218 keepalive with all connections.
6220 * Added silc_task_get_first function into lib/silcutil/silctask.c
6221 to return the timeout task with shortest timeout. There was a bug
6222 in task unregistration that caused problems. TODO has been
6223 updated to include that task system must be rewritten.
6225 * The client library will now resolve the client information when
6226 receiving JOIN notify from server for client that we know but
6227 have incomplete information.
6229 * Rewrote parts of silc_server_remove_from_channels and
6230 silc_server_remove_from_one_channel as they did not remove the
6231 channel in some circumstances even though they should've.
6233 * Encryption problem encountered in server:
6235 The LEAVE command used to send the Channel Key packet to the
6236 router immediately after generating it. However, the code
6237 had earlier sent Remove Channel user packet but not immediately,
6238 ie. it was put to queue. The order of packets in the router
6239 was that Channel Key packet was first and Remove Channel User
6240 packet was second, even though they were encrypted in the
6241 reverse order. For this reason, MAC check failed. Now, this
6242 is fixed by not sending the Channel Key packet immediately but
6243 putting it to queue. However, this is more fundamental problem:
6244 packets that are in queue should actually not be encrypted
6245 because packets that are sent immediately gets encrypted
6246 actually with wrong IV (and thus MAC check fails). So, packets
6247 that are in queue should be encrypted when they are sent to
6248 the wire and not when they put to the queue.
6250 However, the problem is that the current system has not been
6251 designed to work that way. Instead, the packet is encrypted
6252 as soon as possible and left to the queue. The queue is then
6253 just purged into wire. There won't be any fixes for this
6254 any time soon. So, the current semantic for packet sending
6257 o If you send packet to remote host and do not force the send
6258 (the packet will be in queue) then all subsequent packets to the
6259 same remote host must also be put to the queue. Only after the
6260 queue has been purged is it safe again to force the packet
6263 o If you send all packets immediately then it safe to send
6264 any of subsequent packets through the queue, however, after
6265 the first packet is put to queue then any subsequent packets
6266 must also be put to the queue.
6268 Follow these rules and everything works fine.
6270 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Added new function silc_server_remove_clients_by_server to
6273 remove all client entries from ID list when the server connection
6274 is lost. In this case it is also important to invalidate all
6275 client entires as they hold the invalid server entry. This
6276 fixes fatal bug when server has lost connection and will reconnect
6279 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Made some sanity checks to silc_server_daemonise like to check
6282 whether the requested user and group actually exists.
6284 * Added sanity check to SKE's silc_ske_responder_finish to check
6285 that the public and private key actually is valid.
6287 * Invalidate the client's nickname when receiving Replace ID
6288 packet and the Client ID is being replaced. This means that the
6289 server will query the nickname if someone needs it (client)
6292 * Sort the ID Cache in client library when the ID Cache data
6293 has changed (needs sorting).
6295 * Do not allow for SILC client to create several connections to
6296 several servers. The client does not support windows right now
6297 and generating multiple connections causes weird behaviour.
6299 Irssi-silc client does support windows and can handle several
6300 connections without problems, see: www.irssi.org and SILC plugin.
6302 * Fixed some places where client was added to the IDList. The
6303 rule of thumb is following (in order to get everything right):
6304 If the client is directly connected local client then the
6305 `connection' argument must be set and `router' argument must be
6306 NULL to silc_idlist_add_client function. If the client is not
6307 directly connected client then the `router' argument must
6308 bet set and the `connection' argument must be NULL to the
6309 silc_idlist_add_client function.
6311 * The funtion silc_server_packet_send_local_channel actually did
6312 not check whether the client was locally connected or not. It
6313 does that now. Fixed a bug related to LEAVE command.
6315 * Fixed Remove Channel User payload parsing bug in server's
6316 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6318 * The server's silc_server_save_channel_key now checks also the
6319 global ID list for the channel as it might not be in the local
6320 list. Fixed a bug related to LEAVE command.
6322 * Is this the end of the [<unknown>] buglet that has been lurking
6323 around for a long time? A little for loop fix in server's
6324 silc_server_command_whois_parse that is used by both IDENTIFY
6325 and WHOIS command. At least, this was a clear bug and a cause
6326 of one type of [<unknown>] buglet.
6328 * WHOIS and IDENTIFY commands call the function
6329 silc_server_command_[whois/identify]_check function even if
6330 we are not router server.
6332 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Added --with-gmp configuration option. If set the GMP
6335 is always compiled in the SILC source tree. If not set then
6336 it is checked whether the system has the GMP3 installed. If
6337 it has then the GMP won't be compiled (the system's headers
6338 and library is used), if it doesn't have it then the GMP is
6339 compiled in the SILC source tree.
6341 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * Changed RSA private exponent generation to what PKCS #1
6344 suggests. We try to find the smallest possible d by doing
6345 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6346 not security fix but optimization.
6348 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Added new config entry [Identity] to fork the server and run
6351 it as specific user and group. A patch from Bostik.
6353 * Imported Dotconf configuration library into lib/dotconf.
6354 This will be used to create the SILC configuration files later.
6355 It will appear in the distsribution after this commit.
6357 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6359 * A big code auditing weekend happening. Auditing code for
6360 obvious mistakes, bugs and errors. Also, removing any code
6363 Removed files for being obsolete:
6365 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6366 inline in the file lib/silcutil/silcbuffer.h)
6368 o lib/silcutil/silcbufutil.c (the header has inline versions)
6370 Changed code to fix possible error conditions:
6372 o The buffer formatting routines now check that the destination
6373 buffer really has enough space to add the data. This applies for
6374 both buffer formatting and unformatting
6375 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6376 unformatting was changed to accomodate following rules:
6377 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6378 sent to the function while XXX_*STRING will not allocate or copy
6379 the data into the buffer. Instead it sets the pointer from the
6380 buffer into the pointer sent as argument (XXX_*STRING used to
6381 require that the pointer must be allocated already). This change
6382 makes this whole thing a bit more consistent and more optimized
6383 (note that the data returned in the unformatting with XXX_*STRING
6384 must not be freed now). The routines return now -1 on error.
6386 o Tried to find all code that use buffer_format and buffer_unformat
6387 and added return value checking to prevent formatting and
6388 especially unformatting errors and possible subsequent fatal
6391 o Changed ske->x and ske->KEY to mallocated pointers in
6392 lib/silcske/silcske.h. Fixed possible data and memory leak.
6394 o Added return value checking to all *_parse* functions. Fixed
6395 many memory leaks as well.
6397 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6398 so that buffer overflows would not happen. All code now also
6399 checks the return value as it can fail.
6401 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added reconnection support to server if the normal server looses
6404 its connection to the router (for example if router is rebooted).
6405 The server performs normal reconnection strategy implemented
6406 to the server. Affected file silcd/server.c.
6408 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added new packet type SILC_PACKET_SET_MODE that is used to
6411 distribute the information about changed modes (for clients,
6412 channels and clients channel modes) to all routers in the
6413 network. Updated the protocol specification accordingly.
6415 Added functions into silcd/packet_send.c and
6416 silcd/packet_receive.c: silc_server_send_set_mode,
6417 silc_server_set_mode.
6419 Added new files silcmode.[ch] into lib/silccore that implements
6420 the encoding and decoding of Set Mode Payload. Added new type
6421 SilcSetModePayload. Moved the definitions of different modes
6422 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6424 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Oops, a little mistake in server's connection authentication
6427 protocol. The protocol is not ended with FAILURE but with
6428 SUCCESS if the authentication is Ok. :) Affected file is
6431 * Implemented NICK_CHANGE notify handling in server in the file
6432 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6433 the local clients on the channel. After the changing nickname
6434 in router environment snhould work and the [<unknown>] nickname
6435 should appear no more.
6437 The silc_server_replace_id function that receives the Replace ID
6438 payload now sends the NICK_CHANGE notify type also in the file
6439 silcd/packet_receive.c
6441 * Changed WHOIS and IDENTIFY command to support the maximum amount
6442 of arguments defined in protocol specs (3328 arguments). This
6443 fixed a bug that caused problems when there were more than three
6446 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added extra parameter, command identifier, to the
6449 silc_client_send_command so that explicit command identifier
6452 Changed that ID list routines uses specific command identifier
6453 when sending WHOIS/IDENTIFY requests to the server so that they
6454 can be identified when the reply comes back.
6456 Affected files lib/silcclient/command.[ch],
6457 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6459 * Added `sender' argument to silc_server_packet_send_to_channel
6460 to indicaet the sender who originally sent the packet to us
6461 that we are now re-sending. Ignored if NULL. Affected file
6462 silcd/packet_send.[ch].
6464 * Added some server statistics support in silcd/server_internal.h
6465 SilcServerStatistics structure and around the server code. Also
6466 send some nice statistics information when client is connecting
6469 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6471 * Fixed channel ID decoding in server's JOIN command reply in
6472 silcd/command_reply.c
6474 * Fixed braodcasting of replace ID payload to not to send it if
6475 we are standalone server in silcd/packet_receive.c.
6477 * Fixed all channel message sending routines to not to send
6478 packets to clients that has router set, since they are routed
6479 separately in the same function earlier. Affects file
6480 silcd/packet_send.c and all channel packet sending functions.
6482 * In USERS reply, res_argv[i] are not allocated, the table
6483 is allocated. Thus changed that free the table, not its
6486 * In server's whois_check and identify_check if the client is
6487 locally connected do not send any WHOIS commands - they are not
6490 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Fixed some minor bugs in client when sending WHOIS command. The
6493 arguments was in wrong order.
6495 * Removed statis function add_to_channel from server in
6496 silcd/command.c that was previously used with the joining but
6499 * Tested USERS command in router environment successfully with two
6500 routers, two servers and two clients.
6502 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Reorganized the USERS command and command reply in client library
6505 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6506 When the command is given by user we register a pending command
6507 callback that will reprocess the command after the reply has been
6508 received from the server. When reprocessing the packet we then
6509 display the information. Thus, the USERS information is displayed
6510 now in the command callback instead of in the command reply
6511 callback. The processing of the command is same as previously
6512 when server has sent the command reply in the JOINing process.
6514 * Added to USERS command in silcd/command_reply.c to join the client,
6515 we didn't use to know about, to the channel after we've created
6516 a client entry for it. Also, for clienet we did know already still
6517 check whether it is on the channel or not and add it if not.
6519 * Removed silc_server_command_join_notify as the function and its
6522 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Changed the client's pending command handling to the same as the
6525 server's pending command handling. It is also now possible to
6526 execute command reply functions from other command reply
6527 function as the function callbacks for commands and command
6528 replies are one and same. The pending commands are not static
6529 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6530 in client connection context. Thus, pending commands are server
6531 connection specific as it is convenient.
6533 Changed the function silc_client_command_pending and
6534 silc_client_command_pending_del and added new function
6535 silc_client_command_pending_check. Removed the
6536 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6539 * Added cmd_ident, current command identifier, to the client
6540 connection context in lib/silcclient/client.h to keep track on
6541 command identifiers used in command sending. Client's command reply
6542 function handling now supports the mandatory command identifiers.
6544 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6545 funtions in client to fully support pending command callbacks.
6547 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6548 as one of the arguments to the application in the command reply
6551 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6552 before first releasing SILC but came back. Now it is removed again
6553 and should come back nomore. The FORWARDED flag was used only
6554 by the JOINing procedure by forwarding the command packet to router.
6555 Now, the JOINing procedure has been changed to more generic (due
6556 to various router environment issues) and FORWARDED is not needed
6557 anymore for anything. The protocol specification is yet to be
6560 Now, removed silc_server_packet_forward from server and the flag
6561 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6563 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * Renamed NAMES command to USERS command. The NAMES was named that
6566 due to historical reasons. Now it is renamed. Also, rewrote
6567 parts of the USERS command. The nickname list is not sent anymore
6568 by the server. Only Client ID and mode lists are sent in the USERS
6569 command. Changed this also to the protocol specification.
6571 The client now resolves the names and stuff after it receives
6572 the USERS list from the server when joining to the channel.
6574 * WHOIS and IDENTIFY commands has been changed to support multiple
6575 Client ID's per command. One can now search for multiple users
6576 in the network by sending only one WHOIS or IDENTIFY command.
6577 Changed the code and the protocol specifications.
6579 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6580 uses silc_server_command_whois_parse to parse the request. */
6582 * If normal server, do not parse the WHOIS and IDENTIFY requests
6583 before sending it to the router. Saves some time.
6585 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6587 * Fixed JOIN command on client library. Wrong number of arguments
6588 used to crash the client.
6590 * Added silc_server_channel_has_global function to check whether
6591 channel has global users or not.
6593 * Added silc_server_channel_has_local function to check whether channel
6594 has locally connected clients on the channel.
6596 * The silc_server_remove_from_one_channel now checks whether the
6597 channel has global users or not after given client was removed from
6598 the channel. It also checks whether the channel has local clients
6599 on the channel anymore. If it does not have then the channel entry
6600 is removed as it is not needed anymore.
6602 * The silc_server_notify now checks on JOIN notify whether the joining
6603 client is one of locally connected or global. If it is global then
6604 the channel has now global users on the channel and that is marked
6605 to the channel entry. Also, it now saves the global client to
6606 global list who is joining and JOINs it to the channel. This is
6607 for normal server, that is.
6609 Changed silc_server_send_notify_on_channel,
6610 silc_server_packet_relay_to_channel and
6611 silc_server_packet_send_to_channel check if we are normal server
6612 and client has router set (ie. global client) do not send the
6613 message to that client, as it is already routed to our router.
6615 * Implemented LEAVE notify type handling in silc_server_notify
6618 * Tested LEAVE command in router environment successfully. Tested
6619 with two routers, two servers and two clients.
6623 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6625 * Implemented SIGNOFF notify type handling in silc_server_notify
6628 * silc_server_remove_id now removes the client entry from all channels
6629 it has joined and thusly sends SIGNOFF notify type.
6631 * Rewrote the NAMES list generation in server by removing two excess
6632 loops. The lists are created now inside one loop.
6634 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * silc_server_remove_channel_user checks now also global list
6637 for channel and client.
6639 * silc_server_new_channel_user checks now both local and global
6640 list for channel and client. Fixed a bug in client id decoding.
6641 Used to decode wrong buffer.
6643 * silc_server_channel_message checks now both local and global
6644 list for channel entry.
6646 * Tested channel joining (hence JOIN) in router environment
6647 successfully. Tested with two routers, two servers and two
6650 * Tested channel message sending in router environment successfully.
6652 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Added silc_server_save_channel_key into server.[ch] to save the
6655 received channel key in Channel Key payload processing. It is
6656 also used in JOIN command reply handling.
6658 Equivalent function silc_client_save_channel_key added into
6659 client.[ch] into client library.
6661 * Changed JOIN command reply to send information whether the channel
6662 was created or not (is existing already) and the channel key
6663 payload. Changed protocol specs accordingly.
6665 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6666 the request was sent by ID and not by nickname. Crashed on
6669 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6672 now correctly save the received data.
6674 * silc_server_free_sock_user_data now notifies routers in the
6675 network about entities leaving the network.
6677 At the same time implemented functions silc_server_remove_id
6678 and silc_server_send_remove_id to receive and send REMOVE_ID
6679 packets. The packet is used to notify routers in the network
6680 about leaving entities. The ID removed will become invalid in
6683 * Added function silc_idlist_del_server into server. Removes and
6684 free's server entry from ID list.
6686 * silc_server_private_message function now checks, if we are router,
6687 that the destination ID really is valid ID, naturally.
6689 * In router when NEW_ID packet is received (for new client) the
6690 hash of the Client ID is saved in the ID Cache but the
6691 client->nickname is set to NULL, instead of putting the hash
6694 IDENTIFY command now also checks that client->nickname must be
6695 valid. If it is not if will request the data from the server who
6696 owns the client. Added new function
6697 silc_server_command_identify_check.
6699 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6700 to set the command to already allocated Command Payload.
6702 * Tested private message sending in router environment with two
6703 routers, two servers and two clients. Fixed minor bugs and now
6706 * Fixed segfault from client's NAMES command. Used to crash if
6709 * Forwarded packets must not be routed even if it is not destined
6710 to the receiver. Changed server code comply with this.
6712 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added `require_reverse_mapping' boolean value to ServerParams
6715 structure. If TRUE (not default) the server will require that
6716 the connecting host has fully qualified domain name.
6718 If the reverse mapping is not required and hostname could not be
6719 found the IP address is used as hostname.
6721 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Implemented version string checking to both client and server.
6724 The check is incomplete currently due to the abnormal version
6725 strings used in development version of SILC.
6727 * Changed all command functions in server to use the new
6730 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Changed char *data to unsigned char *data in ID Cache system to
6733 support binary data as ID Cache data. Changed code to support
6734 binary data in lib/silccore/idcache.c.
6736 * Renamed silc_server_packet_relay_command_reply to
6737 silc_server_command_reply as it is normal packet receiving
6738 function. Rewrote the function to accept command replys for
6739 servers and not only for clients.
6741 * Mark remote router always as registered server if we are connecting
6742 to it. Otherwise, commands sent by the router to us are ignored.
6744 * All ID List find routines now returns the ID Cache Entry pointer
6745 as well if requested.
6747 * WHOIS command works now in router environment, tested with two
6748 routers, two servers and two clients.
6750 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6751 in router environment (as it is almost equivalent to WHOIS) but
6752 hasn't been tested thoroughly. Added new functions:
6754 silc_server_command_identify_parse
6755 silc_server_command_identify_send_reply
6756 silc_server_command_identify_from_client
6757 silc_server_command_identify_from_server
6759 * Disabled route cache adding because adding two different ID's with
6760 same IP replaces the old cache entry thus giving wrong route.
6761 The entry->router->connection is always the fastest route anyway
6762 so route cache may not be needed. Of course, new routes maybe
6763 established after receiving the ID when the entry->router->connection
6764 might not be anymore the most optimal.
6766 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Add route cache for received ID for fast routing.
6770 * Added silc_server_packet_route to route received packet on router
6771 that is not destined to us.
6773 * Renamed silc_server_get_route to silc_server_route_get.
6775 * Added id_string and id_string_len fields into SilcServer to
6776 include encoded ServerID for fast comparing without excess
6777 encoding of the ID's.
6779 * Cleaned up WHOIS command on server side. Added following static
6782 silc_server_command_whois_parse
6783 silc_server_command_whois_check
6784 silc_server_command_whois_send_reply
6785 silc_server_command_whois_from_client
6786 silc_server_command_whois_from_server
6788 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6789 arguments in command replies. All command functions should be
6790 updated to use this macro.
6792 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Minor typo fixes on command reply handling on server.
6796 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Added silc_server_command_add_to_channel internal routine to add
6799 the client to the channel after router has created the channel and
6800 sent command reply to the server.
6802 * Added generic silc_server_send_command to send any command from
6805 * Use static buffer with ID rendering instead of duplicating data.
6807 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Fixed a channel user mode bug when joining to a channel server gave
6810 everybody channel founder rights, oops.
6812 * We mark ourselves as the router of the incoming server connection
6813 if we are router ourselves. This way we can check in some packet
6814 sending functions whether it is locally connected server. For
6815 incoming router connections we put NULL.
6817 * For router sending packets locally means now always sending the
6818 packet cell wide; to local clients and local servers. For normal
6819 server sending packet locally means sending it to only local
6822 * Fixed the JOIN command to really work in router environment. If the
6823 channel is created it is always created by the router. Router is
6824 also responsible of making the initial joining to the channel,
6825 sending JOIN notify to the sending server and distributing
6826 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6827 does not exist server doesn't do anything else but forward the
6828 command to the router which performs everything.
6830 * Added silc_server_send_channel_key function to send the Channel Key
6833 * Added silc_server_create_channel_key to create new channel key. The
6834 channel key is now re-generated everytime someone joins or leaves
6835 a channel, as protocol dictates. Note: channel->key_len is the
6838 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6841 packet_receive.[ch] to separate packet sending and receiving
6842 routines. The server.[ch] now includes everything else including
6843 actual packet processing (writing and reading data) and other
6846 Renamed silc_server_private_message_send_internal to
6847 silc_server_send_private_message. The routine is still though
6848 used only to relay private messages as server does not send
6849 private messages itself.
6851 Renamed silc_server_new_channel to silc_server_create_new_channel
6852 and added new function sicl_server_new_channel that handles the
6853 incoming New Channel packet. Added also new sending function
6854 silc_server_send_new_channel to send New Channel Payload.
6856 * Added new function silc_server_notify to process incoming notify
6857 packet to the server/router. Server may then relay the notify
6858 to clients if needed.
6860 * Added new function silc_server_new_channel_user to process incoming
6861 New Channel User packet. Router will redistribute the packet and
6862 send JOIN notify to its local clients and locally connected servers
6863 if needed. Normal server will send JOIN notify to its local client
6864 on same channel when received this packet. Added also corresponding
6865 sending function silc_server_send_new_channel_user to sent the
6868 * Added boolean route argument to send_notif_to_channel and
6869 packet_send_to_channel functions to attempt to route the packet
6870 if it is TRUE and send only locally if it is FALSE.
6872 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * silc_server_replace_id now broadcasts the received replace ID
6875 packet if it is not broadcast packet already. The router must
6876 broadcast to inform other routers about changed ID.
6878 * Added backpointer to server's router into SilcServer context in
6879 silcd/server_internal.h.
6881 * Fixed silc_server_packet_broadcast to send correct broadcast
6884 * The channel key is now distributed to the local client as soon
6885 as it is received from the router (in router environment) so that
6886 no other packet may be sent for the channel until client has
6889 * silc_server_remove_channel_user now broadcasts the received
6890 Remove Channel User packet if it is not broadcast packet already.
6891 The router must broadcast to inform other routers about removed
6894 * Added users field into SilcPacketContext that is a reference count
6895 of the context. One can increase the reference count by calling
6896 silc_packet_context_dup which is now changed to just increase the
6897 reference count instead of duplicating the data. The reference
6898 count is decresed by calling silc_packet_context_free that will
6899 free the data after the reference count hits zero.
6901 For now on the packet context and everything allocated into it
6902 (including the raw packet from network) must be freed by calling
6903 the new silc_packet_context_free function. Added also new function
6904 silc_packet_context_alloc that must be used now to allocate the
6905 context. This also means that if a routine is asynchronous from
6906 silc_[client/server]_packet_parse_type the packet context must
6907 be duplicated by calling silc_packet_context_dup. Otherwise it
6908 gets free'd after silc_[client/server]_packet_parse_type returns.
6909 Also, one must remember that if packet is duplicated then its
6910 reference count must be decresed by calling the free function as
6911 many times as it was duplicated.
6913 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6914 from both client and server.
6916 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Made joining to a channel working in router environment.
6920 * Cleaned up JOIN command on server side and create function
6921 silc_server_command_join_channel internal routine to make the
6924 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Changed silc_command_pending list to SilcDList. Also, added
6927 `ident' field to SilcServerCommandPending structure to identify
6928 the reply and to call correct callback.
6930 Added silc_server_command_pending_check function to replace the
6931 corresnponding macro. The silc_command_pending list is not
6934 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6935 to set identifier to previously allocated Command Payload. It
6936 is used to set identifier for command when resending Command
6939 * Added silc_command_payload_encode_payload to encode Command
6940 Payload buffer from SilcCommandPayload structure.
6942 * Added silc_argument_payload_encode_payload to encode Argument
6943 payload buffer from SilcArgumentPayload structure.
6945 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Changed WHOIS command to support router connection on server side.
6948 The whois request is always sent to router unless the server is
6949 standalone server. After server has received the reply from the
6950 router will it send the reply to the client.
6952 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6953 broadcast received broadcast packet. The function is used only
6954 by router. The broadcast packet is always sent to the router's
6957 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6958 render given ID to printable string, for log files for example.
6960 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Made basic router to router connections working. At least they
6963 can now connect to each other but nothing really works the way
6964 they are supposed - yet.
6966 * Added new initiator token to RouterConnection configuration
6967 file in silcd/serverconfig.[ch]. It is used to tell whether we
6968 are the initiator to the remote router or whether we'll expect
6969 the other end to connect.
6971 * Moved registering of listener task to silc_server_init, hence
6972 the server starts listenning as soon as it is run, even if it
6973 does not have connections to other routers. Let's see how well
6976 * Changed default connection retry timeouts for more suitable in
6979 * Removed cipher and such arguments from silc_idlist_add_client
6980 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6981 Added new function silc_idlist_add_data to add the keys and stuff
6984 * Added SilcIDListData structure and added it to SilcClientEntry
6985 and SilcServerEntry as their first field in the structure. This
6986 way we can explicitly cast the ID entries to the SilcIDListData
6987 structure and get common data for the entries. In past, we had
6988 to first check what type of connection it is and then cast it to
6989 correct ID entry type. Now, we can directly cast the opaque
6990 pointer to the SilcIDListData (no matter what ID entry it actually
6991 is) and get the data needed.
6993 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6996 in some circumstances even if threre were timeout tasks, though not
6997 IO tasks, but tasks anyway. Now fixed.
6999 * Defined SilcServerConnection structure to hold connection specific
7000 stuff about directly connected servers and routers. The definition
7001 is currently in silcd/server_internal.h. I thought about having
7002 a bit more important role fro this struct but for now it is used
7003 only when connecting to other server (or router actually).
7005 * Added connecting retry support in server when connecting to
7006 router(s). The retry feature implement exponential backoff
7007 algorithm. Also, added SilcServerParams structure to hold default
7008 parameters for server. For now, it include these retry settings
7009 and are hard coded. After server is moded to be as Silc Server
7010 Library this structure will be more important.
7012 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7014 * Changed client librarys channel->clients table to SilcList and
7015 changed code accordingly.
7017 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7019 * Changed client's channel table to SilcList and changed code
7020 accordingly. Also changed SilcChannelClientEntry to include back-
7021 pointer to the channel so that client entry can use that structure
7022 as list as well and we have fast cross-reference to the channel.
7023 This change dramatically decreased the complexity of channel
7024 handling with client entry and vice versa (removed one extra
7025 loop when searching for channel entry from many functions).
7027 * Changed server->sim from table to SilcDList and changed code
7030 * NAMES command can now be used from user interface. It will show
7031 the user list on the channel, neatly.
7033 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7034 Code now saves realname of the user if it becomes available.
7036 * Renamed configure.in to configure.in.pre and made ./prepare
7037 script to automatically add correct version string to
7038 configure.in which it creates from configure.in.pre.
7040 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * NAMES command reply now shows users mode with the nickname when
7045 * Moved silc_client_ch[u]mode[_char] functions from
7046 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7047 place sucks, they are utility functions and should be in some
7050 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7052 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7055 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7059 * Added TRQ (efficient deque and list library) into lib/trq. This is
7060 a very good list library that is currently used in the SILC. Defined
7061 SilcList API over the library because I didn't like the API very
7062 much. See lib/trq/silclist.h for the API and examples of how to
7063 use the API. Fixed various places in the code to use the new
7064 SilcList API. The SilcList is meant for lists that has a structure
7065 already defined as a list. It is not suitable to add just some
7066 context to the list (in TRQ, the context is the list actually).
7068 So, I defined SilcDList that can be used for the purpose where
7069 predefined list structure does not exit. This can be used as
7070 such list. Now some context just can be added to the SilcDList.
7071 Currently this list is not used in the SILC just yet, though there
7072 are a lot places where this can replace dynamically allocated
7073 tables and I will fix these places, later, to use SilcDList.
7074 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7075 and use TRQ internally).
7077 Also fixed some annoying warning messages that the original TRQ
7078 code generated. Also minor changes to TRQ's Makefile.in.
7080 * Added support for querying by Client ID to both WHOIS and
7081 IDENTIFY commands into server, as required by the protocol.
7083 * Removed method function pointers from SilcBuffer structure. They
7084 weren't used to anything and just increased the context size for
7085 no good reason. This change also made silc_buffer_alloc and
7086 silc_buffer_free functions inline functions.
7088 * Disabled command flooding detection support until it's fixed so
7089 that it accepts commands in but does not execute them more than once
7092 * Added silc_net_localhost(), to return local hostname, into
7093 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7094 that must be initialized before calling silc_client_init.
7096 * Added new function: silc_server_send_notify_on_channels to send
7097 notify messages to all channels client has joined. It is assured
7098 that the message is sent only once per client.
7100 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7101 lib/silcutil/silcutil.[ch] as silc_format function. The new
7102 function is generic and is used by server as well, not only by
7103 the logging routines.
7105 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7106 the provided version string was not acceptable. Added new function:
7107 silc_ske_check_version into lib/silcske/silcske.h. The function
7108 must be implemented by the application (client or server) and it
7109 does not reside in the SKE library. The function checks the version
7110 string remote end sent.
7112 * Added back pointers (to opaque context and to SilcSocketConnection)
7113 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7115 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7116 duplicate packet context structure.
7118 * Changed `notify' client operation to send same arguments as client
7119 receives from server except for ID's. ID's are mapped to correct
7120 ID entry and that is returned. Also, if channel entry is not sent
7121 by server but the notify is for channel the channel entry is sent
7122 to application (otherwise application doesn't know that it is for
7123 channel (library gets it from packet's Destination ID)).
7125 * Added silc_client_remove_from_channels into client library to
7126 remove a client from all channels it has joined to. Used when
7127 received SIGNOFF notify from server. Added also new function
7128 silc_client_replace_from_channels to replace old ID entry with
7129 new ID entry on all channels. Used when received NICK_CHANGE
7132 * Fixed ID Cache list handling in silc_idlist_get_client in
7133 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7134 to get (or query) client by ID.
7136 * Updated TODO list.
7138 * Added connection authentication status message defined by the
7139 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7140 support for these into the code in client and server side.
7142 * Added generic function silc_client_send_command to send any command
7143 with variable argument list. Application should use this function
7144 to send commands if the command functions provided by the library
7145 does not suite for the application's user interface needs.
7147 * Added new `failure' client operation. Application is notified about
7148 received failure packet if client is executing a protocol. In this
7149 case the protocol's execution has failed.
7151 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7152 is required by the protocol.
7154 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7155 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7158 * Added status flag to SilcSKE object to indicate realtime status
7159 of the SKE protocol.
7161 * Application receives now exactly same command reply arguments as
7162 the library receives from server. However, if ID is received the
7163 corresponding ID entry is returned to the application (eg. Client
7164 ID is mapped to correct SilcClientEntry entry and that is returned).
7165 Changed command_reply client operation due to this change.
7167 * Changed all ID's in commands and in command replys as ID Payloads.
7168 Change affected both client and server side codes.
7170 All ID's sent in SILC network (with execption of ID's in SILC
7171 Packet header) are sent in ID Payload to support variable length
7174 * Server now notifies nick changes and notifies all clients on
7175 the channels about the new nickname (about the new Client ID,
7178 * Implemented CMODE command to change channel modes. Supports all
7179 channel modes defined by the protocol specs except ban and invite
7180 lists. (Also, private channel key mode is supported but support for
7181 setting private channel key in client is missing, thus, this mode
7182 has no effect on client side (except that server requires that the
7183 client uses private channel key and normal channel traffic does not
7186 Also, invite mode works per se, but INVITE command does not work
7187 yet correctly, so you can set channel as invite only channel but
7188 inviting clients to the channel does not work (it is yet to be
7189 thought what's the best way to do it).
7191 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7192 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7193 Implemented CUMODE command to change user's mode on the channel.
7194 Supports all modes defined by the protocol specs.
7196 * Added NAMES command reply to return users modes on the channel.
7198 * Removed unnecessary and slow ciphers from lib/silccrypt.
7200 * Set SO_KEEPALIVE option to connection sockets by default.
7202 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7204 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7205 redefined the Notify Payload into protocol specs.
7207 * Added silc_id_payload_parse_id to get ID directly from raw
7210 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7213 accept searching by Client ID as well.
7215 * Added support for LEAVE and SIGNOFF notify types in client library.
7217 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7218 to parse ID Payload from raw data.
7220 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7222 * Added flags parameter into silc_ske_assemble_security_properties
7223 function in lib/silcske/silcske.[ch].
7225 * Changed notify client operation to fit better for notify messages
7226 sent by server. The notify payload received from server is now
7227 passed to the application (after parsing it to SilcNotifyPayload).
7228 It is application's responsibility to retrieve the arguments
7229 from the payload and show the message the way it wants. The message
7230 sent by server is implementation specific.
7232 * Changed public keys to comply with the protocol specification.
7233 Old public keys are not supported anymore and are not compatible.
7235 * Removed nickname from Channel Payload as the latest draft removed
7236 it. The client must resolve the nickname from the NAMES command
7237 reply received when it joined the channel.
7239 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7241 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7243 * Fixed some errors in protocol specification drafts.
7245 * Created lib/silccore/silcnotify.c to implement Notify Payload
7246 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7247 generic payloads described by protocol specifications. The file
7248 includes implementations for ID Payload and Argument Payload.
7250 * Changed Command Payload implementation to use the new Argument
7251 Payload. Changed command_xxxx_payload to command_payload_xxxx
7252 to comply with SILC coding conventions.
7254 * Added suppport for Argument Payload handling in Notify Payload
7255 implementation as protocol requires it. Added the new support
7256 into server and client lib as well.
7258 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7260 * Added support for multiple nicknames on same channel. [n] is
7261 added locally to the nickname if there are more than one same
7262 nicknames on the channel.
7264 * Server now sends all nicknames that matched WHOIS request.
7265 Client also shows the list received from server.
7267 * Added TOPIC command to client side. User can now set and show
7268 current topic on channel.
7270 * Added MOTD command to client and server. Also, server sends the
7271 motd when client connects to the server.
7273 * Changed version strings to comply ISO 8601.
7275 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7277 * Fixed protocol error handling in client library. It should now
7278 cope even if the SKE fails for some reason.
7280 * Made new protocol specification drafts for submitting to IETF.
7282 * Implemented TOPIC command to server in silcd/command.c.
7284 * Added two new notify types into lib/silccore/silcnotify.h:
7285 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7286 notify nickname change and topic setting/change on a channel.
7288 * API change of command_reply operation in client library. The
7289 application gets now the status type received from server as well.
7291 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7295 * Cras fixed and optimized the packet handling even further and
7296 it should work now. Minor change to the prototype of function
7297 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7299 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Added new function into lib/silcutil/silcschedule.[ch]:
7302 silc_schedule_with_fd to select() a specified fd. The function
7303 returns after timeout expires or data arrives or goes. The
7304 function is used by packet routines to wait that all data is
7305 received from network.
7307 * Fixed data reading from network in lib/silccore/silcpacket.c.
7308 The code now assures that all data is read from the fd and then
7309 continues packet processing. This was a bug fix since the code
7310 used to drop some data in some circumstances.
7312 * Added new function into lib/silcclient/client.[ch]:
7313 silc_client_start_key_exchange to start key exchange after
7314 connection has been established to server. The code internally
7315 now uses this funtion but its main purpose was to provide it
7316 for applications that perform their own connecting. After
7317 application has created a connection it merely calls this
7318 function to start the key exchange between client and server.
7319 The library takes care of everything else after that.
7321 Updated also lib/silcclient/README to explain the usage of
7324 * Do not send to application information that connection has
7325 been established. Application gets notified it by connect
7328 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * Applied cras's patch to add silc_schedule_one function. The
7331 function runs scheduler once and returns.
7333 * Fixed the scheduler after cras messed it up. The timeout
7334 handling works now as it's supposed to work.
7336 * Added into lib/silccore/ silcnotify.h to include notify
7337 message types support. Changed silc_server_send_notify*
7338 functions, in server.[ch], to support those new notify types.
7339 Added the support for the notify types into client library,
7340 as well. Added new notify client operation into ops.h in
7343 * Changed silc_server_packet_send_to_channel to send normal
7344 packets instead of just channel message packets. The function
7345 is now used to send the notify packets to channels. It is not
7346 used to send channel message packets anymore, as server never
7349 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7350 va_arg()s as it seems to require it nowadays. I guess, if SILC
7351 is compiled with older va_arg() the new code should work anyway.
7353 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7355 * Splitted core library. Core library (lib/silccore) includes
7356 now only SILC protocol specific core (and common) components.
7357 Created new utility library (lib/silcutil) that includes more
7358 generic purpose stuff. The stuff for util library was taken
7359 from the old core library. This was minor and easy split.
7361 * Created SILC Client Library (lib/silcclient) that includes
7362 implementation of the SILC client without user interface. This
7363 was major move from silc/ directory. The code has been changed
7364 so that it is transparent towards the user interface. The
7365 silc/ directory includes now the same user interface as before
7366 and it uses the new client library. Read lib/silcclient/README.
7367 Basicly, the client library performs everything else related
7368 to SILC except user interface handling. Also, configuration
7369 files are considered to be part of user interface and library
7370 does not handle them.
7372 This change also changed a lot of structures, function naming etc.
7373 Most important change was that SilcClientWindow object was
7374 renamed to SilcClientConnection in the client library. Created
7375 also new file lib/silcclient/ops.h. Also added new files
7376 silc/local_command.[ch] and silc/client_ops.[ch].
7378 All these changes were made to make it easier for user interface
7379 designers to create what ever user interface for the SILC client
7382 It is also expected that the server will be moved to lib
7383 directory as well and SILC Server Library will be created;
7384 sometimes in the future.
7386 * Removed Local commands from lib/silccore/silccommand.h as
7387 they are application specific and new client library does not
7388 handle any of those anymore.
7390 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7391 old client implementation in silc/.
7393 * Added support for callback functions in SILC_LOG_* macros.
7394 Application can now set its own callbacks that will be called
7395 instead of using the default functions that will always print
7396 the debug messages to stderr (or stdout). Also, debugging can
7397 now be disabled by setting silc_debug to FALSE and re-enabled by
7398 setting it to TRUE. Note, that logging will still work even
7399 if debugging is disabled.
7401 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7402 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7403 silc_log_reset_debug_callbacks.
7405 * To enable debugging in silc client one must give now -d
7406 option on command line.
7408 * Changed silc_schedule_init to automatically allocate task queues
7409 if they are not allocated before calling it.
7411 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7413 * Added GMP 3.1 into math library.
7415 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7417 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7418 a channel in SILC network. The packet is used by servers and
7419 routers to notify other routers that user has left a channel.
7420 This little feature was missing until now. Added the feature
7421 to protocol specification as well.
7423 Added functions: silc_server_send_remove_channel_user and
7424 silc_server_remove_channel_user into server.[ch].
7426 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7427 lib/silccore/silcpacket.h. However, they are not implemented
7430 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7432 * Fixed joining to a channel and sending channel messages
7433 between server and router. The channel message sending should
7434 now work inside a cell.
7436 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7438 * Fixed the private message sending between server and router.
7439 The private message sending should now work inside a cell.
7441 * Added silc_server_replace_id into server.[ch] to replace
7442 existing ID in the SILC network.
7444 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7445 and silc_idlist_replace_server_id into idlist.[ch] in server.
7447 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Fixed the server to server connections. Server can again now
7450 connect to router. Router to router connections probably does
7453 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7455 * Added dynamic protocol registering support. Now protocols can
7456 registered and unregistered on the fly. Patch by cras.
7458 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Added lib/contrib directory to hold routines that some platforms
7461 don't have but are needed by SILC.
7463 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7464 into lin/contrib to provide getopt() and getopt_long() for
7465 those who don't have it.
7467 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Added AWAY command to client. When away message is set and
7470 client receives a private message packet the client automatically
7471 replies to the sender with the away message.
7473 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7474 bug seemed to be the cause of recent problems when compiling
7477 * Added version detection support to SKE protocol specification
7478 and added the new changes to the SKE implementation as well.
7479 There were other minor changes in the SKE protocol as well.
7481 Many changes in lib/silcske/silcske.[ch] and in
7482 lib/silcske/payload.[ch].
7484 * Added ^U functionality, clear input line. Patch from cras.
7486 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * Mainly small bugfixes on core library. Fixed some debugging
7489 logging and buffer overflow in silclog.c.
7491 * Updated config.sub and config.guess on the distribution tree.
7493 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Added command lagging support in server. Client may execute
7496 commands now only once in two seconds.
7498 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Optimized packet reception. MAC computation and checking is now
7501 also more optimized. A lot previously duplicated code is now
7502 used as generic by both client and server.
7504 * Fixed key pair generation in clientutil.c
7506 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Added into lib/silccore/silcbufutil.[ch] new function;
7509 silc_buffer_realloc.
7511 * Moved generic packet sending/encryption functions to
7512 lib/silccore/silcpacket.[ch] from client and server. Some
7513 rewriting of the functions.
7515 * Moved all generic packet reception/decryption functions to
7516 lib/silccore/silcpacket.[ch] from client and server. The
7517 packet processing is now much cleaner in both client and server.
7518 These were major changes in both client and server.
7520 * Created many common functions in server to do packet sending.
7521 Previously code were duplicated a lot, this has been removed
7524 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Rewrote major parts of the ID cache system. Don't know
7527 whether it is better now or not but at least the API is more
7530 * Major rewrite on ID cache stuff on client because of the ID
7531 cache API changes. Added idlist.c to client.
7533 * Also major rewrite on ID cache stuff on server as well.
7534 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7535 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7536 in hand, instead they are all put into the ID cache system now.
7537 All server_idlist_* routines uses ID cache now instead of
7538 traversing its own lists (those lists does not exist anymore).
7539 SilcIDList though still exists. Also, SilcXXXEntry's are
7542 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Finally made the SKE implementation compliant to the protocol
7545 specification. All mp integers are now binary encoded as
7546 opposed being HEX encoded.
7548 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7551 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7552 functions: silc_[encode/decode]_pem. Also added function
7553 silc_encode_pem_file to PEM encode with newlines ('\n') for
7556 * SILC public keys are now encoded either PEM or binary. Same
7557 option is for private keys as well. By default private keys
7558 are binary encoded and public keys PEM encoded. Silly HEX
7559 encoding were removed.
7561 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7562 function to create fingerprints.
7564 * Fixed a bug in SHA1; does not change the original data anymore.
7566 * Partly implemented INFO command on client and server side.
7567 Fixed CLEAR command. Changes to SERVER command; show current
7568 server(s) when giving command without arguments. Added
7569 VERSION command to client.
7571 * Added check to server that unregistered connections cannot
7572 execute commands (unless it is specificly allowed).
7574 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7576 * Fixed screen refresh.
7578 * Fixed channel joining bug from client. On some circumstances
7579 client tried to join to a channel it had already joined.
7581 * Added public key verification process into client's protocol.c.
7582 The client now verifies the public key from user and saves
7583 it into ~./silc/serverkeys/ directory.
7585 Added into: clientutil.[ch]: silc_client_verify_server_key.
7587 * Changed SKE protocol's silc_ske_initiator_finish function
7588 to accept callback function that verifies the received public
7589 key. Removed old silc_ske_verify_public_key function.
7591 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7594 silc_pkcs_private_key[_data]_set.
7596 * Made the password and public authentication more cleaner in
7597 server's protocol.c.
7599 * Removed historic and obsolete protocol `channel_auth' from
7600 both client and server.
7602 * Removed wrong way of sending command status messages from
7603 server to client in server's command.c. The old way violated
7604 protocol specification.
7606 Changes to silccore/silccommand.[ch]: removed
7607 silc_command_encode_status_payload -> not needed anymore,
7608 changed silc_command_encode_payload_va to accept extra
7609 argument on variable argument list. The argument type must
7610 now be provided to the function. Also, added new function:
7611 silc_command_encode_reply_payload_va which is same as
7612 normal command_encode_payload_va except command status type
7613 is provided as extra argument.
7615 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Added ~./silc directory handling. The directory includes the
7618 public and private keys for the client.
7620 Added silc_client_check_silc_dir, silc_client_create_identifier
7621 and silc_client_load_keys.
7623 * Implemented SILC protocol compliant public key. Added public
7624 and private key saving to and loading from files.
7626 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7627 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7628 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7629 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7630 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7632 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7633 silc_pkcs_load_[public/private]_key.
7635 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7637 * Added silc_server_get_route (route.[ch]) to get connection
7638 data for the fastest route for given ID.
7640 * Implemented INVITE command on client and server. The command
7641 were re-defined in the SILC Protocol Specification and the
7642 implementation now complies with the specification.
7644 * Implemented PING command on client and server.
7646 * Implemented NAMES command on client and server. The server side
7647 supports currently only normal server not router server yet.
7648 Some changes to NAMES definition in SILC protocol specification.
7650 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7652 * Implemented LEAVE command on client and server.
7654 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7655 again. This change was made to the protocol as well. Server
7656 should not violate the protocol specification anymore.
7658 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7660 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7661 was tested. SOCKS4 was not but should work anyway.
