3 * Added functions silc_server_config_[ref/unref], these are used
4 to prevent that the config object is destroyed.
6 No longer directly affect global variables silc_log_quick and
7 silc_log_delay, they are first cached inside the config object
8 and then applied with silc_server_config_setlogfiles().
10 silc_server_config_set_defaults() is now internal to
11 serverconfig.c, there are no reasons to show this internal stuff
14 Affected files are silcd/serverconfig.[ch].
16 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
17 fprintf's to stderr, since some code may be executed again after
18 the server went into the background. Affected files are
21 * Added rehash support. Added function silc_server_rehash() that
22 will perform all the basic tasks of the rehashing procedure.
24 * Added command line option `-x, --hexdump'. This will enable the
25 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
26 The option `--hexdump' implies `--debug'.
28 * Fixed a bad bug in the logging APIs (silcutil library) where
29 the application would crash after calling silc_log_reset_all().
31 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
33 * Fixed the KICKED notify handling in client library to
34 correctly remove the channel and all entries from the
35 channel when I was kicked. This bug crashed the client.
37 Fixed yet another but in KICKED notify handling to remove
38 the kicked client correctly from the channel.
40 Affected file is lib/silcclient/client_notify.c.
42 * Fixed a minor bug in looking up correct client entry
43 in KICKED notify in server. Affected file is
44 silcd/packet_receive.c.
46 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
47 sources correctly to distribution. Fixes --with-gmp option.
49 * Removed the manual rehashing from ID Cache, and changed it
50 to use the SILC Hash Table's auto rehash feature. Affected
51 file is lib/silccore/silcidcache.c.
53 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
55 * Fixed a bug in the silc_client_nickname_format function that
56 handles the multiple same nickname formatting. Two clients
57 with same nickname caused problems after the first one left
58 and rejoined. It didn't format the nickname correctly.
59 Affected file is lib/silcclient/idlist.c.
61 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
63 * Don't change the topic if olod topic is same as new one.
64 Affected file is silcd/packet_receive.c.
66 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
68 * Added cross-reference support to the SILC Documentation
69 generator. All types across all HTML files are now cross-
70 referenced. Affected files util/robodoc/generator.c and
71 scripts/silcdoc/silcdoc.
73 * Added file lib/silcutil/silctypes.h to include all the
74 arithmetic type definitions and some macros. Removed
75 includes/bitmove.h and moved macros to silctypes.h.
77 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
79 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
81 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
83 * Added `type' argument to silc_id_payload_parse_id function which
84 now returns the type of the ID to the sent pointer. Affected
85 file is lib/silccore/silcid.[ch].
87 * Added check for CMODE_CHANGE notify type that mode change is
88 allowed by the sender. Affected file silcd/packet_receive.c.
90 * Added check for CUMODE_CHANGE notify type that mode change is
91 allowed by the sender. Affected file silcd/packet_receive.c.
92 Added the ID type as CUMODE_CHANGE notify type as argument
93 to the `notify' client operation. Affected files are
94 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
96 * Added function silc_client_add_server to the client library.
97 Added support for resolving also channel and server info when
98 received unknown entity in notify packet. Affected files are
99 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
101 * Added function silc_command_get_status to return the command
102 status from the command reply's argument payload. Affected files
103 are lib/silccore/silccommand.[ch].
105 * Added check for KICKED notify type that the kicking is
106 allowed by the client. Affected file silcd/packet_receive.c.
108 * Created function silc_get_input which can be used to get input
109 (echo on or off) from user on command line. Affected files are
110 lib/silcutil/silcutil.[ch].
112 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
114 * Optimized silc_server_packet_relay_to_channel function.
115 Added new function silc_channel_message_payload_encrypt which
116 can be called directly if channel message payload needs to
117 be encrypted and is already encoded (no need to call _encode
118 function). Packet relaying is now done by router without any
119 extra memory allocations. Affected files are
120 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
123 * Fixed the INVITE notify handling. It took wrong arguments
124 as invite list and invite delete. Affected file is
125 silcd/packet_receive.c.
127 * Added check for TOPIC_SET notify type that the topic change is
128 allowed by the client. Affected file silcd/packet_receive.c.
130 * Added check for INVITE notify type that inviting is allowed by
131 the client. Affected file silcd/packet_receive.c.
133 * Changed the silc_server_client_on_channel to return the
134 SilcChannelClientEntry as well. Moved the function
135 silc_server_check_cmode_rights to server_util.[ch].
136 Affected files are silcd/server_util.[ch], silcd/command.c.
138 * Added function silc_server_check_umode_rights to check whether
139 changing client's user mode is allowed. Added check for
140 UMODE_CHANGE notify type that the umode change is allowed
141 by the client. Affected files are silcd/server_util.[ch],
142 silcd/packet_receive.c and silcd/command.c.
144 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
147 ID length. It ignored that ID can be IPv6 based as well.
148 Affected file lib/silccore/silcpacket.h.
150 * Fixed the silc_id_id2str and silc_id_str2id to take the
151 IPv6 address offset's into consideration. Affecte file is
152 lib/silccore/silcid.c.
154 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Fixed the internal Unix scheduler functions to check for
157 NULL context they may receive. The affected file is
158 lib/silcutil/unix/silcunixschedule.c.
160 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
162 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
163 can specify different directory with --home command line
164 parameter. Affected files irssi/src/silc/core/client_ops.c,
167 * SILC-specific commands aren't now executed if the active server
168 isn't of SILC-type, so there won't be problems with having
169 IRC and SILC protocol support in same client. Affected files
170 irssi/src/silc/core/silc-channels.c, silc-servers.c,
173 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
175 * Improved the signal support in SILC Schedule. Added new
176 function silc_schedule_signal_call which is used by application
177 to mark a signal to be called. It is now safe to perform
178 any kind of tasks in signal callbacks since it is guaranteed
179 that the application specified signal callback is called
180 after the signal is over. Affected files are
181 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
183 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
185 * Added `name' field to SilcChannelPrivateKey to represent
186 application given name for the key. Moved also the context from
187 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
188 Added the `name' argument also to the function
189 silc_client_add_channel_private_key.
191 Added function silc_client_current_channel_private_key to set the
192 current channel private key in use.
194 Added "change" command to KEY command which can be used to change
195 the current channel private key. Bound the command also to
198 Also affected files lib/silcclient/client_channel.c,
199 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
201 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
203 * Added silc_rng_get_byte_fast function in to the
204 lib/silccrypt/silcrng.[ch].
206 * Changed the interface of silc_packet_assemble and the
207 silc_packet_send_prepare. If silc_packet_assmble is now
208 called the application does not call silc_packet_send_prepare
209 because the library will call it automatically. These
210 interfaces now also return a reference to the outgoing buffer
211 which includes the assembled packet, which the application can
212 use to encrypt the packet.
214 Affected files are lib/silccore/silcpacket.[ch],
215 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
216 silcd/packet_send.c, server_backup.c and packet_receive.c.
218 * Fixed a packet sending bug on very high load, where outgoing
219 packet queue wasn't handled correctly and packets got corrupted.
220 Affected files are lib/silcutil/*/silc*sockconn.c,
221 lib/silcclient/client.c and silcd/server.c.
223 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Added macro SILC_PACKET_DATALEN which can be used during
226 packet assembling to check whether the data to be added to
227 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
228 len is truncated until it fits it.
230 Added checks for maximum length of channel message payload and
231 private message payload also.
233 Added checks for maximum packet length in server and in
236 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
237 lib/silcclient/client.c, lib/silccore/silcchannel.c and
238 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
239 lib/silcclient/client_prvmsg.c.
241 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Added silc_server_packet_queue_purge call to the
244 silc_server_disconnect_remote to assure that all data in the
245 queue before disconnecting is sent to the network. Affected
248 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
250 * Added the deleting of server's own ID cache entry to the
251 silc_server_free function. Free also everything else that
252 has been allocated in silc_server_init. The affected file
255 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Added functions silc_parse_version_string, silc_version_to_num,
258 and silc_ske_parse_version to parse SILC protocol style version
259 strings. Affected files lib/silcutil/silcutil.[ch] and
260 lib/silcske/silcske.[ch].
262 * Added new configuration params: version_protocol, version_software
263 and version_software_vendor to specify what version the remote
264 host must at least be to be able to connect to server. The vendor
265 string can be regex matched too. Added new function
266 silc_server_connection_allowed to check maximum number of allowed
267 connections, and allowed versions for incoming connections.
268 Affected files are silcd/server.c, server_util.[ch] and
271 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
273 * Added preliminary support for signals in scheduler. The
274 signals we care about are now blocked always when the scheduler
275 is locked. This way we can synchronise the use of signal with
276 scheduler. It is guaranteed that when signal occurs the scheduler
277 is not locked, and thus new tasks can be safely added to the
280 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
281 to silc_schedule_internal_init and silc_schedule_internal_uninit.
282 Added new platform specific routines
283 silc_schedule_internal_signals_[un]block and
284 silc_schedule_internal_signal_[un]register.
286 Added new functions to SILC Schedule API:
287 silc_schedule_signal_[un]register. Each signal that application
288 is going to use should be registered to the scheduler.
290 Affected files are lib/silcutil/silcschedule.[ch],
291 lib/silcutil/*/silc*schedule.c.
293 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
295 * Check for unauthenticated client and server in the
296 silc_server_new_client and silc_server_new_server functions.
297 Affected file silcd/packet_receive.c.
299 * Added function silc_string_is_ascii to check whether given
300 string is 7-bit ASCII string. Affected files are
301 lib/silcutil/silcutil.[ch].
303 * Added function silc_id_is_valid_server_id into the
304 silcd/serverid.c and added checking for valid Server ID's in
305 silc_server_new_server. The Server ID must always be based
306 on the server's public IP address.
308 * Added logging of DISCONNECT packet message in the server.
309 Affected file silcd/server.c.
311 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
313 * Changed all library interfaces that use Global RNG to also
314 accept SilcRng as argument. Affected files are
315 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
316 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
317 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
318 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
321 * Added function silc_pkcs_generate_key to the
322 lib/silccrypt/silcpkcs.[ch] for applications so that they
323 don't need to do pkcs->pkcs->init calls anymore.
325 * Remove SilcSocketConnection from the SFTP API since it really
326 wasn't needed there. The application has the information
327 saved in its contexts anyway and the SFTP layer doesn't need
328 know about it. Affected files lib/silcsft/silcsftp.h and
329 lib/silcsftp/sftp_[server/client].c.
331 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
332 The SilcSimContext is not SilcSim.
334 * Fixed possible buffer overflows in silc_id_render in the
335 lib/silcutil/silcutil.c.
337 * On EPOC the global crypto module lists are not used at all
338 in the crypto library. Added support for using the constant
339 algorithm list on EPOC. Affected files are
340 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
343 * Fixed the handling of third parameter of KICKED notify, since
344 it was mistakenly updated to SILC Protocol 1.0 even though it
345 is to be included in 1.1. Since it is not in 1.0 it is not
346 mandatory, and this fix now handles it only if it is provided,
347 and it is not error if it is not provided. Affected file
348 lib/silcclient/client_notify.c.
350 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
352 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
353 client. Affected file irssi/src/silc/core/client_ops.c.
355 * Merged with Irssi 0.8.4 from irssi.org CVS.
357 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Check for valid socket connection in client entries before
360 sending any messages. Fixes a crash, but doesn't fix some
361 other underlaying bug that is lurking there. Affected
362 file silcd/packet_send.c.
364 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
366 * $usermode, $cumode and $cumode_space expandos shouldn't do
367 anything with non-SILC server records. Affected file
368 irssi/src/silc/core/silc-expandos.c
370 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
372 * Fixed the silc_net_check_[host/local]_by_sock to support
373 IPv6 bound sockets as well. Now they can return IPv6 addresses
374 as well. Affected file lib/silcutil/silcnet.c.
376 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
377 Affected lib/silcutil/unix/silcunixnet.c.
379 * Fixed ID rendering (at least on some platforms, not NetBSD)
380 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
382 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
384 * Added silc_hash_public_key and silc_hash_public_key_compare
385 functions to be used with SilcHashTable. They can be used to
386 hash public keys and compare public keys in hash table. Affected
387 file lib/silcutil/silcutil.[ch].
389 * Added support for specifying multiple public keys for Client
390 connection section in server configuration file. This makes it
391 possible to accept multiple public keys from same host, or to
392 make a section that accepts any incoming host, and have the
393 accepted public keys listed in the section.
395 Added functions silc_sever_[find/get]_public_key, added the
396 support for this actually to all connection sections but only
397 the Client section is currently allowed to specify multiple
400 Affected files are silcd/server.c, server_internal.h,
401 command.c, protocol.c, server_util.[ch], packet_receive.c.
403 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
405 * Merged Irssi 0.8.2 from irssi.org CVS.
407 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
409 * If silc_debug is TRUE, also output standard logging messages
410 to stderr with the debug output.
412 Made silc_log_reset_all() flushing all channels before returning.
413 Also fixed some documentation typos.
415 Affected files are lib/silcutil/silclog.[ch].
417 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
419 * Fixed the server to check correctly the amount of connections
420 from single host, by checking also the type of the connection.
421 Fixed also the comparison of number of connections and number
422 of allowed connections. Affected files are silcd/server.c,
425 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Fixed the USERS command reply to save the user's mode on the
428 channel as well. Fixed JOIN command reply to check whether a
429 client is on channel already and not join it twice. Affected
430 file lib/silcclient/command_reply.c.
432 * Added new file silc-expandos.c into irssi/silc/core/ to return
433 various stuff for various signal for the statusbar etc. updating.
434 Now Irssi SILC client prints channel user modes etc. on the
437 * The user mode (like server/router operator changes) is now shown
438 on the Irssi SILC client's statusbar. The affected files are
439 irssi/src/silc/core/client_ops.c, silc-expandos.c.
441 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
443 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
444 to SILC_SCHEDULE_[UN]LOCK macros.
446 * Added more error printing to logs in server code. Affected
447 files silcd/server.c and silcd/protocol.c.
449 * Fixed -S option parsing in Irssi SILC Client. Affected file
450 irssi/src/silc/core/silc-core.c.
452 * Added silc_buffer_alloc_size function. Affected file is
453 lib/silcutil/silcbuffer.h.
455 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
458 constants. Affected files in
459 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
462 * Changed the internal SFTP Memory FS table to const. Affected
463 file lib/silcsftp/sftp_fs_memory.c.
465 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
467 * Fixed the buffer formatting and unformatting routines to
468 check the size of 64 bits types with sizeof(). Affected
469 file is lib/silcutil/silcbuffmt.c.
471 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
473 * Removed 0.6.x backwards support.
475 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Changed all integer type names:
478 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
479 to avoid collisions with other libraries using same type names
482 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Added `prefer_ipv6' argument to the functions
485 silc_net_gethostbyname[_async]. If it is TRUE it will return
486 IPv6 address over IPv4. If FALSE IPv4 address is returned
487 even if IPv6 address was found. Affected files
488 lib/silcutil/silcnet.[ch].
490 * Added support silc_net_create_connection[_async] to fallback
491 to IPv4 address if IPv6 address could not be used (like if
492 it doesn't work on a specific system). Affected file in
493 lib/silcutil/unix/silcunixnet.c.
495 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
497 * Added silc_schedule_reinit function to do the enlarging
498 of the max tasks handling capabilities of the scheduler.
499 Affected files lib/silcutil/silcschedule.[ch].
501 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Added automatic extern "C" { ... } for C++ compilers so the
504 application does not need to define them. Affected file
505 includes/silcincludes.h.
507 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
508 old name went against naming convention. Applications now
509 include "silcclient.h" instead of "clientlibincludes.h".
510 Removed includes/clientlibincludes.h, it is redundant now.
512 * Renamed includes/version.h to silcversion.h.
514 * Added really preliminary support for OS/2 into the util
515 library. Only thread & mutex API is implemented, others
516 are still to be implemented. Created the lib/silcutil/os2/
517 directory. Created also file includes/silcos2.h.
519 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Added preliminary BeOS support into the util library.
522 Created lib/silcutil/beos/, and implemented all the needed
523 functions to support SILC on BeOS. Created also file
526 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
528 * Added proper initializations to silc's irssi code, so it's

552 in normal server of global channels as well. Affected files
553 silcd/server.c, idlist.h, packet_receive.c and command.c.
555 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

572 the SKE interface a bit.
574 * Fixed padding problem in PKCS#1. The padding was not actually
575 random since the random number generator was used incorrectly.
576 This security bug affects only when encrypting with PKCS#1, and
577 it is not currently used at all in SILC. SILC only use signing
578 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
580 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

654 whether given configuration value has been given already.
656 Affected files silcd/serverconfig.[c], server.[c].
658 * Splitted the doc/example_silcd.conf.in. Separated the crypto
659 algorithm parts and created new file silcalgs.conf, that
660 is now included from the example_silcd.conf.in.
662 * Optimized the silc_server_connect_to_router_second to take
663 the connection configuration object from the SilcServerConnection
664 object instead of finding it during the connecting phase.
665 Added the configuration object to SilcServerConnection struct.
666 Affected files silcd/server_internal.h, server.c.

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

746 hash algorithm. Affected file lib/silccrypt/silcrng.c.
748 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
750 * Fixed the file transfer's key agreement payload to include
751 zero port also if the hostname is NULL because it could not
754 Call file transfer monitor callback now also if error occurs
755 during key agreement protocol.
757 Changed the silc_client_file_send interface to return the
758 SilcClientFileError instead of session id. The session ID
759 is returned into pointer provided as argument.
761 Check that the file exists locally before sending the
762 file transfer request at all.
764 Affected file lib/silcclient/client_ftp.c, silcapi.h.

776 file lib/silcutil/silclog.c.
778 * Fixed the channel message payload decryption in the function
779 silc_channel_message_payload_decrypt to not modify the original
780 buffer before it is verified that the message decrypted
781 correctly. Otherwise, next time it is called with correct
782 channel key it won't encrypt since the payload is corrupted.
783 Affected file lib/silccore/silcchannel.c.
785 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

823 silc_client_new_channel_id and silc_idlist_get_channel_by_id
826 * Added cross reference of the joined channels to the
827 SilcClientEntry, and changed the SilcChannelEntry's
828 users list to SilcHashTable. The affected files are
829 lib/silcclient/idlist.[ch].
831 * Fixed a bug in hash table tarversing. While the hash table
832 is traversed with SilcHashTableList the table must not be
833 rehashed. It is now guaranteed that auto rehashable tables
834 are not rehashed while tarversing the list. Also defined that
835 silc_hash_table_rehash must not be called while tarversing
836 the table. Added function silc_hash_table_list_reset that must
837 be called after the tarversing is over. The affected files are
838 lib/silcutil/silchashtable.[ch].
840 * Changed all hash table traversing to call the new
841 silc_hash_table_list_reset in server and in client library.
843 * Added function silc_client_on_channel to return the
844 SilcChannelUser entry if the specified client entry is joined
845 on the specified channel. This is exported to application as
846 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

855 lists correctly. Affected file silcd/command.c.
857 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
859 * When sending JOIN command to router for processing the
860 sender's old command identifier was not saved back to the
861 sender's command context, fixed now. The affected file is
864 * Create the key in JOIN command of the router did not return
865 the channel key, added check for this. Affected file is
868 * Fixed a channel ID update bug in JOIN command reply. Do
869 not directly upgrade the ID but call the function
870 silc_idlist_replace_channel_id if the ID was changed.
871 Affected file silcd/command_reply.c.
873 * Fixed memory leaks from command calling if it would fail.
874 Affected file silcd/command.c.

886 * Removed TRQ from lib/trq, not needed anymore.
888 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
889 with server connections. Later this will be configurable
890 in config file after new config file is done. Affected file
893 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Fixed a crash in server related to channel announcements.
896 Affected file silcd/server.c.
898 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
900 * Fixed memory leaks in silc_server_create_new_channel*
901 functions. Affected file silcd/server.c.
903 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
904 which ID was changed. This way the router will send the
905 user list for the channel again, and server won't be in
906 desync in some rare circumstances. Affected file is
907 silcd/packet_receive.c.
909 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

938 file silcd/packet_receive.c and silcd/command.c.
940 * Fixed the SERVER_SIGNOFF notify handling on normal server
941 not to save the history information for clients. Same was
942 fixed earlier in remove_clients_by_server function, but not
943 here. Affected file silcd/packet_receive.c.
945 * Raised the default connection-retry count from 4 to 7 in
946 server. Affected file silcd/server.h.
948 * Cancel any possible reconnect timeouts when we start the

969 little bug. Affected file silcd/command.c.
971 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
973 * Removed the SilcClientCommandDestructor from the client
974 libary, it is not needed anymore. Affected files are
975 lib/silcclient/silcapi.h, command[_reply].[ch],
976 client_notify, idlist.c.
978 * Fixed GETKEY command to first resolve client, and then
979 resolve the server only if the client was not found, instead
980 of resolving both at the same time. Affected file is
981 lib/silcclient/command.c.
983 * Added silc_client_start_key_exchange_cb and lookup the
984 remote hostname and IP address before starting the key
985 exchange with server. The affected file is
986 lib/silcclient/client.c.
988 * The server's public key is now saved using the IP address
989 of the server and not the servername for the filename.
990 The hostname public key filename is checked as an fall back
991 method if the IP address based filename is not found.
993 Fixed the GETKEY command to save the fetched server key
996 Print the remote server's hostname now when new key is
997 received during connection process. Affected file is
998 irssi/src/silc/core/client_ops.c.
1000 * Return always our own public key to the client if it asks
1001 for it with GETKEY command. Affected file silcd/command.c.
1003 * Removed the use_auto_addr variable from default config
1004 file since it was in wrong section. Affected file is

1009 Affected file silcd/command.c.
1011 * Fixed silc_server_send_notify_kicked to send the kicker's
1012 Client ID also, it was missing. Affected files are
1013 silcd/command.c, silcd/packet_send.[ch].
1015 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Do not save client history information in SERVER_SIGNOFF.
1018 Fixes the bug in normal server that it does not detect
1019 the client becoming valid after the server becomes back
1020 online. Affected file silcd/server_util.c.
1022 * Added `sock_error' field into the SilcSocketConnection
1023 context. When error occurs during socket operation (read
1024 or write) the error is saved. Added also new function
1025 silc_socket_get_error to return human readable socket error
1026 message. Affected files are lib/silcutil/silcsockconn.[ch],
1027 lib/silcutil/unix/silcunixsockconn.c, and

1030 * The server now prints the socket error message in the
1031 signoff for client. Affected file silcd/server.c.
1033 * Fixed the `created' channel information sending from router
1034 to server in JOIN command. Checks now whether the channel
1035 really was created or not and set it according that.
1037 Fixed the JOIN command to use the client entry's current
1038 ID during the joining procedure instead of the one it sent
1039 in the command (it is checked though), since it can change
1040 between the packet processing and command processing, and
1041 would just case unnecessary pain in the client end. Affected
1042 file silcd/command.c.
1044 * Fixed a channel key payload sending to use correct channel
1045 ID when the server was forced to change the channel's ID by
1046 router. Router sent the key payload with the old Channel ID.
1047 Affected file silcd/packet_receive.c.
1049 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1064 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1066 * Simple handling of TERM and HUP signals. Also added some log
1067 flushing call around. Affected file is
1070 * Fixed small bugs in silclog.c. Now buffering output will take
1071 effect after 10 seconds since startup: This will ensure that
1072 no important startup messages are lost. Also output redirection
1073 will preserve original format ([Date] [Type] message).
1074 Affected file is lib/silcutil/silclog.c.
1076 * Added two options to the config file, in the logging section:
1077 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1078 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1080 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1083 more than once to avoid excess logging. Affected file is
1084 lib/silcutil/silclog.c.
1086 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1087 the SIM copying in make install in Makefile.am.pre.
1089 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1091 * Rewritten silclog APIs. Globally interesting changes follows:
1092 silc_log_set_files() changed to silc_log_set_file().
1093 silc_log_set_callbacks() changed to silc_log_set_callback().
1094 ROBOdoc documented silclog header file.
1095 SilcLogCb now returns bool to wether inihibit the default
1096 handler or not (to keep the old behaviour return always TRUE).
1097 The new APIs should also fix the problem of the
1098 silcd_error.log file that was written in the current directory.
1101 Log files streams will remain opened after silc_log_set_file()
1102 call, means less CPU usage notably on high traffic servers.
1103 File streams are now full buffered, and flushed to the disk
1104 every 5 minutes, lesses HD activity and CPU usage.
1105 Messages can be redirected, allowing admins to configure
1106 one single logfile for all server messages.
1107 the silc_log_quick global variable to activate fast-logging.
1108 Affected files lib/silcutil/silclog.[ch]
1110 * Changed some code to conform new silclog APIs. Affected
1111 files are doc/example_silcd.conf.in, silcd/server.c
1112 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1115 * Fixed a memory leak that could occur in some situations.
1116 Affected file silcd/serverconfig.c.
1118 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1120 * Added the silc_client_del_client to remove the client from
1121 all channels as well. Affected file lib/silcclient/idlist.c.
1123 * Fixed the client library to correctly remove the client
1124 from all channels when the client entry is being destroyed.
1125 Affected file lib/silcclient/client_notify.c, command.c.
1127 * Added auto-nicking support to the client library. If the
1128 applicatio now sets client->nickname it will be sent to the
1129 server after connecting by the library. This way for example
1130 SILCNICK (or IRCNICK) environment variables will have effect
1131 and always change the nickname automatically to whatever
1132 it is wanted. Affected file lib/silcclient/client.[ch].
1134 * Renamed silc_server_command_bad_chars to the
1135 silc_server_name_bad_chars and moved it to the
1136 silcd/server_util.[ch]. Added also new function
1137 silc_server_name_modify_bad to return nickname that
1138 includes bad characters as new nickname without those
1139 bad characters. This check and modify is now used in
1140 silc_server_new_client when the username is initially set
1141 as nickname, so it must be checked to be valid nickname.
1142 Affected file silcd/packet_receive.c.
1144 * The nickname length is now taken from the packet for real
1145 and not trusted to strlen() since it clearly can return
1146 wrong length for nickname including bad characters. This
1147 also applies to channel names. Affected file silcd/command.c.
1149 * Removed the lib/silcsilm/modules directory. Modules are now
1150 compiled into the lib/silcsim. Fixed the copying of the
1151 modules to follow symbolic links in Makefile.am.pre.
1153 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1155 * Fixed silc_string_regexify list creation. Fixes bugs with
1156 BAN and INVITE commands in server. The affected file is
1157 lib/silcutil/unix/silcunixutil.c.
1159 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * Removed the command destructor entirely from the server's
1162 command and command reply routines. It is not needed, and
1163 its usage was buggy and caused crashes. Affected files are
1164 silcd/command[_reply].[ch].
1166 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Cancel protocol and NULL sock->protocol if timeout
1169 occurred during protocol. Affected file silcd/server.c.
1171 * Cancel protocol timeouts always before calling the final
1172 callback, to assure that after final callback is called
1173 no other state will be called for the protocol anymore.
1174 Affected file silcd/protocol.c.
1176 * Print error log if incoming connection configuration could
1177 not be found. Affected file silcd/server.c.
1179 * Fixed JOIN command to correctly save the founder mode
1180 to the client on normal SILC server, when the channel
1181 was created by the router. Affected file silcd/command.c.
1183 * Fixed LIST command (hopefully) to send correct reply
1184 packets. Affected file silcd/command.c.
1186 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * The silc_packet_receive_process now returns FALSE if the
1189 read data was invalid packet, and TRUE if it was ok.
1191 The server now checks that if unauthenticated connection
1192 sends data and its processing fails the server will close
1193 the connection since it could be a malicious flooder.
1195 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1197 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Make sure the warning about error opening a log file is
1200 printed only once and not everytime it fails (produces
1201 too much useless log). Affected file lib/silcutil/silclog.c.
1203 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1205 * Made the silc_server_daemonise() function more readable.
1206 Affected file silcd/server.c.
1208 * Pid file is now optional, the user may comment it out from
1209 the config file. Removed define SILC_SERVER_PID_FILE, we
1210 don't need a default any longer. Affected file
1211 configure.in.pre, lib/Makefile.am.pre.
1213 * Make some use of the pid file. The server now dies at startup
1214 if it detects a valid pid file on his path. The server would
1215 die anyway in this circumstance, because of the bind() failure.
1216 Affected file silcd/silcd.c.
1218 * No longer compiling lib/dotconf.
1220 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Fixed JOIN command parsing not to crash. Affected file
1223 lib/silcclient/command.c.
1225 * Fied the NICK_CHANGE notify to add the new client entry
1226 even it is resolved. This removes an <[unknown]> nick
1227 thingy bug in the client. Affected file is
1228 lib/silcclient/client_notify.c.
1230 * Do not try to allocate 0 bytes (efence does not like it)
1231 in lib/silccore/silccomand.c when encoding payload.
1233 * Do not take IRCNICK as nickname in Irssi SILC client since
1234 it is not possible to set nickname before hand connecting
1235 the server (TODO has an entry about adding auto-nicking
1238 * Changed the silc_server_command_pending to check whether
1239 there already exists an pending entry with the specified
1240 command, command identifier and pending callback. This is
1241 to fix IDENTIFY and WHOIS related crashes that may register
1242 multiple pending commands with same identifier. Affected
1243 file silcd/command.c.
1245 * Fixed the server to reconnect to the router even if it
1246 was already reconnecting and EOF was received. This to
1247 fix a possibility that the server wouldn't ever try to
1248 auto-reconnect to the router. Affected file silcd/server.c.
1250 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Fixed the server's password authentication to use the
1253 length of the locally saved password, and not the one
1254 sent in the packet. Affected file silcd/protocol.c.
1256 * Fixed same password authentication problem in the
1257 Authentication Payload handling routines in
1258 lib/silccore/silcauth.c.
1260 * Yet another password authentication problem fixed with
1261 channel password handling in silcd/command.c.
1263 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * If first character of string in silc_parse_userfqdn is '@'
1266 then do not parse it. Affected file is
1267 lib/silcutil/silcutil.c.
1269 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1271 * Fixed minor bug in IDENTIFY command reply sending, which
1272 caused various weird problems during JOIN when it was
1273 resolving names for users. Affected file silcd/command.c.
1275 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Fixed the IDENTIFY command reply sending to chech better valid
1278 clients. It was possible to send incomplete list of replies.
1279 Affected file silcd/command.c.
1281 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Added silc_client_command[s]_[un]register functions now to
1284 dynamically register the commands in client library. Removed
1285 the static table of commands. This allows the client library
1286 to call commands without causing the application to know about
1287 what commands library has called.
1289 Removed the INFO command reply kludge to detect when the command
1290 was called by library. Now library use its own command reply
1291 function for INFO command.
1293 Added function silc_client_command_call to call a command.
1294 Application can use it to call command, not access the structure
1297 Now all commands that are sent by the client library (not
1298 explicitly sent by application) use own command reply functions.
1300 Affected files around lib/silcclient/ and in
1301 irssi/src/silc/core/.
1303 * Fixed the WHOIS command reply sending to chech better valid
1304 clients. It was possible to send incomplete list of replies.
1306 Fixed the WHOIS and IDENTIFY to send the request to router
1307 if normal server did not do it and did not find any results.
1309 Affected file silcd/command.c.
1311 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Moved the internal data from SilcClient context into its
1314 own file, not accesible to application. Affected files
1315 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1316 and other files in client library.
1318 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1320 * Added doc/examples installation target in Makefile.am.pre.
1323 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1326 commands the found client entry will be removed from the
1327 cache, after notifying application about the error. Affected
1328 file lib/silcclient/command_reply.c.
1330 * Changed the /MSG to check for exact nickname user gave, and
1331 not let `nick' match `nick@host' if it is only one found. Now,
1332 user must type the exact nickname (like nick@host2) even if
1333 there are no more than one same nicks found. This is to avoid
1334 a possibility of sending nickname to wrong nickname since
1335 `nick' could match `nick@host'. Affected file is
1336 irssi/src/core/silc-servers.c.
1338 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Do not print "you are now server operator" or similar when
1341 giving /away command. Affected files are
1342 irssi/src/silc/core/client_ops.c, silc-servers.h.
1344 * Made the silc_server_command_pending_error_check to send
1345 the same command reply payload it received back to the
1346 original sender of the command. This way all arguments
1347 that was received by the server will be received by the
1348 client too. Affected file silcd/command.c.
1350 * Added the silc_idcache_add to return the created cache entry
1351 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1353 * Add global clients to expire if they are not on any channel.
1354 This is because normal server will never know if they signoff
1355 if they are not on any channel. The cache expiry will take
1356 case of these entries. This is done by normal servers only.
1357 The affected files are silcd/command_reply.c,
1358 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1360 * If server receives invalid ID notification for WHOIS or
1361 IDENTIFY and the ID exists in the lists, it is removed.
1362 Affected file silcd/command_reply.c.
1364 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1365 in client then client entry that it matches is searched and
1366 the nickname is printed on the screen for user. Affected
1367 file irssi/src/silc/core/client_ops.c.
1369 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Use cache entry expire time in the LIST command reply to
1372 purge old entries from the cache after the LIST command
1373 reply has been received. This way we don't have non-existent
1374 entries in the cache for too long. Affected file is
1375 silcd/command_reply.c.
1377 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * If we are normal server, and we've not resolved client info
1380 in WHOIS or IDENTIFY from router, and it is global client,
1381 we'll check whether it is on some channel. If it is not
1382 then we cannot be sure about its validity and will resolve it
1383 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1384 file silcd/command.c.
1386 * Search channel by name (if possible) rather than by ID
1387 in IDENTIFY command's command reply. Affected file is
1388 silcd/command_reply.c.
1390 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1393 Updated specs and implemented it. Affected file silcd/command.c,
1394 silcd/packet_send.c and silcd/packet_receive.c.
1396 * Implemented the <founder auth> payload handling in the JOIN
1397 command. If provided all conditions for channel joining
1398 except requirement to provide correct passphrase can be
1399 overrided by the channel founder. Updated the protocol specs.
1400 Affected file silcd/command.c.
1402 Added support for founder auth in JOIN command in client
1403 library. Fixed the parsing of the JOIN command now to support
1404 all options as they should be. The affected file is
1405 lib/silcclient/command.c.
1407 * Optimized the WHOIS and IDENTIFY commands to send the request
1408 to router only if it includes nicknames or other names. If
1409 they include only IDs then check the local cache first before
1410 routing. Affected file is silcd/command.c.
1412 * Added channels topic announcements. Affected file is
1413 silcd/packet_receive.c and silcd/server.c.
1415 * Fixed the silc_server_send_notify_topic_set to really destine
1416 the packet to channel. Affected file silcd/packet_send.c.
1418 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1419 library. Affected file lib/silcclient/client_notify.c.
1421 * Added UMODE announcements. Affected file silcd/server.c.
1423 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1425 * Memory leak fixes in:
1427 lib/silcutil/silcsockconn.c
1428 lib/silcske/silcske.c
1429 lib/silcske/groups.c
1431 lib/silccrypt/silcpkcs.c
1432 lib/silccore/silccommand.c
1433 lib/silccore/silcidcache.c
1438 * ROBOdoc documented the lib/silcske/groups.h file and a
1439 bit changed the interface for better.
1441 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1443 * Update the client entry context in the ID cache after
1444 nick change. Affected file lib/silcclient/command.c.
1445 Fixes the CUMODE command when regaining founder privileges,
1446 and a little WHOIS problem.
1448 * Fixed silc_net_gethostbyname to correctly call the
1449 inet_ntop. Affected file lib/silcutil/silcnet.c.
1451 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1453 * Added IPv6 support checking to the configure.in.pre, added
1454 also --enable-ipv6 option to override the check. Affected
1455 file configure.in.pre.
1457 * The silc_thread_create now calls the start function
1458 directly if threads support is not compiled in. Removes
1459 ugly #ifdef's from generic code. Affected files are
1460 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1462 * Added silc_net_gethostby[name/addr]_async to asynchronously
1463 resolve. Affected files are lib/silcutil/silcnet.[ch].
1465 * Added support for rendering IPv6 based server, client and
1466 channel IDs. Affected file lib/silcutil/silcutil.c.
1468 * Added support for creating IPv6 based server IDs. Affected
1469 file is silcd/serverid.c.
1471 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1473 * Added silc_net_gethostby[addr/name] into the
1474 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1475 routines. Added silc_net_is_ip[4/6]. Affected file is
1476 lib/silcutil/unix/silcunixnet.c. All routines that take
1477 address as argument now supports both IPv4 and IPv6 addresses.
1479 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1481 * Fixed LIST command reply sending in server. Affected file
1484 * Server now sends the kicker's client ID in the KICK notify
1485 to the kicked client. Affected file silcd/command.c.
1487 * The client library now parses the kickers client ID and
1488 UI displays it. Affected files lib/silcclient/client_notify.c
1489 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1491 * Made all payload parsing function prototypes consistent.
1492 They all take now const unsigned char * and uint32 pair as
1493 the payload data instead of SilcBuffer. Changes all around
1494 the source tree. Other unsigned char* -> const unsigned char*
1495 changes around the tree as well.
1497 * Optimized SFTP client and server packet sending not to
1498 allocate new buffer for each packet but to recycle the
1499 first allocated buffer. Affected files are
1500 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1502 * Optimized the SFTP client to use SilcList instead of
1503 SilcDList for requests, because it is faster. Affected file
1504 is lib/silcsftp/sftp_client.c.
1506 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1507 into lib/silccore/silcid.[ch].
1509 Renamed silcpayload.[ch] into silcargument.[ch].
1511 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * If client entry is deleted with active key agreement
1514 session, abort the session.
1516 The silc_client_abort_key_agreement now calls the completion
1517 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1519 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1522 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1524 * Don't use __restrict in older GCC's. Affected file is
1525 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1527 * silc_net_localhost now attempts to reverse lookup the
1528 IP/hostname. Affected file lib/silcutil/silcnet.c.
1530 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1531 command. It can be used to gain founder privileges at
1532 the same time when joining the channel.
1534 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1535 kicker's client ID as well. Updated protocol specs.
1537 Defined that the server must send SILC_COMMAND_IDENTIFY
1538 command reply with error status to client who sent
1539 private message with invalid client ID.
1541 Updated the protocol specification.
1543 * Added silc_server_send_command_reply to send any
1544 command reply. Affected file silcd/packet_send.[ch].
1546 * Added silc_id_payload_encode_data to encode ID payload
1547 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1549 * The server now send IDENTIFY command reply with error
1550 status if client ID in private message is invalid. Affected
1551 file silcd/packet_receive.c.
1553 * Save the server key file with server's IP address in
1554 the filename instead of hostname. The affected file is
1555 irssi/src/silc/core/client_ops.c.
1557 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1559 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1562 * Added libtool support for compiling shared objects in
1563 lib/silcsim. Affected file configure.in.pre and
1564 lib/silcsim/Makefile.am. Original patch by cras.
1566 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Pid file configuration, and server's config file fixes
1569 patch by toma. Updated CREDITS file.
1571 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Fixed silc_client_channel_message to not try to decrypt
1574 the message twice if it resolved the destination client
1575 information. This could cause of dropping one channel
1576 message. Affected file lib/silcclient/client_channel.c.
1578 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1581 lib/silcclient/client.c. This function is used when the SILC
1582 Client is run under some other scheduler, or event loop or
1583 main loop. On GUI applications, for example this may be
1584 desired to used to run the client under the GUI application's
1585 main loop. Typically the GUI application would register an
1586 idle task that calls this function multiple times in a second
1587 to quickly process the SILC specific data.
1589 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1591 * Fixed silc_server_drop() for dropping the supplementary
1592 groups as well, this could cause a security hole on some
1595 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1600 * Write PID file after dropping privileges. Added -F option
1601 to run server on foreground. A patch by debolaz.
1602 Affected files silcd/server.c, silcd/silcd.c.
1604 * Fixed MOTD to return the MOTD file server name. Affected
1605 file silcd/command.c.
1607 * Added INFO command reply handling to the Irssi SILC Client.
1608 Affected file irssi/src/silc/core/client_ops.c.
1610 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Fixed the silc_idcache_list_* routines to really support
1613 the dynamic list. Fixes a crash. Affected file is
1614 lib/silccore/silcidcache.c.
1616 * Fixed the LIST command reply to really call LIST command's
1617 pending callbacks. Affected file silcd/command_reply.c.
1619 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1621 * Update conn->local_entry->nickname after giving NICK
1622 command. Affected file lib/silcclient/command.c.
1624 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1626 * Added the [pid] option to the silcd configuration file
1628 Affected files: serverconfig.[ch] and silcd.c
1630 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Save fingerprint in WHOIS command reply in server.
1633 Affected file silcd/command_reply.c.
1635 * Fixed NICK commands pending callback registration.
1636 Affected file lib/silcclient/command.c.
1638 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Use ++server->cmd_ident when sending commands in server,
1641 instead of random number. Affected file silcd/command.c.
1643 * Fixed GETKEY command reply to call actually GETKEY pending
1644 command callbacks. Affected file silcd/command_reply.c.
1646 * A bit stricter check for nicknames. Check for same nickname
1647 in NICK command also. Affected file silcd/command.c.
1649 * Do not call INFO command everytime client ID changes, only
1650 during first connecting. Affected file lib/silcclient/client.c.
1652 * Set the new nickname only after successful command reply for
1653 NICK command is returned by server. Affected file
1654 lib/silcclient/command.c.
1656 * Remove nicknames from nicklist during server_signoff notify.
1657 Should fix /NAMES bit more. The affected file is
1658 irssi/src/silc/core/silc-channels.c.
1660 * Added `fingerprint' field to the SilcIDListData in the
1661 silcd/idlist.h to hold the fingerprint of the client's
1664 Send the fingerprint of the client's public key in WHOIS
1667 Affected files silcd/command.c, and silcd/idlist.[ch].
1669 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1670 create fingerprint from given data.
1672 * Show the fingerprint of the client's public key in WHOIS.
1673 Affected files irssi/src/module-formats.[ch] and
1674 irssi/src/silc/core/client_ops.c.
1676 * Format the multiple same nicknames also during JOIN and
1677 NICK_CHANGE notifys. Affected file is
1678 lib/silcclient/client_notify.c.
1680 * Do not print error on screen for invalid private message
1681 payload since it can come if someone is sending private
1682 messages with wrong key. Affected file
1683 lib/silccore/silcprivate.c.
1685 * Fixed multiple concurrent /PING crash. Affected file
1686 lib/silcclient/command.c.
1688 * Changed the wrong ID encoding. All IP addresses must be
1689 in MSB first order in encoded format. They were encoded
1690 wrong and was in LSB format. Affected files are
1691 silcd/serverid.c, lib/silcutil/silcutil.c.
1693 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1695 * Call the `connect' client operation through the scheduler
1696 in case of error. Affected file lib/silcclient/client.c.
1698 * Call the `failure' client operation even if the error
1699 occurred locally during a protocol. Affected file is
1700 lib/silcclient/protocol.c.
1702 * Added support of sending LIST command to router from normal
1703 server. This way normal server can get list of all channels
1704 in the network too. Fixed the channel list sending in the
1705 server too. Affected files are silcd/command.c, and
1706 silcd/command_reply.[ch].
1708 * Added silc_server_update_channels_by_server and
1709 silc_server_remove_channels_by_server. They are used during
1710 disconnection of primary router and in backup router protocol.
1711 Affected file silcd/server_util.[ch], silcd/server.c and
1712 silcd/server_backup.c.
1714 * Fixed channel adding to global list in IDENTIFY command
1715 reply in server. Affected file silcd/command_reply.c.
1717 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1719 * If the incoming packet type is REKEY or REKEY_DONE process
1720 that packet always synchronously. Fixes yet another MAC
1721 failed error on slow (dialup) connections. Affected file
1722 lib/silcclient/client.c and silcd/server.c.
1724 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Call check_version SKE callback for initiator too. Affected
1727 file lib/silcske/silcske.c.
1729 * Implemented fix for security hole found in the SKE that was
1730 fixed in the specification few days back; the initiator's
1731 public key is now added to the HASH value computation.
1732 Added backwards support for the old way of doing it too, for
1733 old clients and old servers. Affected file is
1734 lib/silcske/silcske.c.
1736 * Enabled mutual authentication by default in SKE. If initiator
1737 is not providing mutual authentication the responder will
1738 force it. This will provide the proof of posession of the
1739 private key for responder. The affected files are
1740 lib/silcclient/protocol.c and silcd/protocol.c.
1742 * Do not cache anymore the server's public key during SKE.
1743 We do mutual authentication so the proof of posession of
1744 private key is done, and if the server is authenticated in
1745 conn auth protocol with public key we must have the public
1746 key already. Affected file silcd/protocol.c.
1748 * Added new global debug variable: silc_debug_hexdump. If
1749 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1750 file lib/silcutil/silclog.[ch].
1752 * Fixed compilation warning due to char * -> const char *.
1753 Affected files lib/silcutil/silcnet.h, and
1754 lib/silccore/silcauth.[ch].
1756 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Fixed CMODE command when new channel key was created. If
1759 the creation failed the old key was removed. Next time giving
1760 same command would crash the server since the old key was
1761 freed already. Affected file silcd/command.c.
1763 * Fixed the silc_server_announce_get_channels to not crash
1764 on reconnect. Affected file silcd/server.c.
1766 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Added silc_log_set_debug_string function to set a regex
1769 string to match for debug output. Only the function names,
1770 or filenames matching the given debug string is actually
1771 printed. This way it is possible to filter out those debug
1772 strings that user is not interested in.
1774 Fixed a bug in silc_string_regexify.
1776 Affected files lib/silcutil/silclog.[ch], and
1777 lib/silcutil/unix/silcunixutil.c.
1779 * Changed the -d options in both server and Irssi SILC client
1780 to take the debug string as argument. Affected files
1781 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1783 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Added silc_hash_babbleprint to create a Bubble Babble
1786 Encoded fingerprint. The encoding is developed by Antti
1787 Huima (draft-huima-babble-01.txt), and it creates human
1788 readable strings out of binary data. Affected file
1789 lib/silccrypt/silchash.[ch].
1791 * Print the babble print now in addition of fingerprint as well
1792 in Irssi SILC client. Affected files are
1793 irssi/src/fe-common/silc/module-formats.[ch],
1794 irssi/src/fe-common/silc/core/client_ops.c.
1796 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Fixed a security problem found in SKE. The initiator's
1799 public key too is now added to the HASH hash value creation
1800 which is signed by the responder to create the SIGN value.
1801 This will prevent anyone in the middle to lie to the responder
1802 about the initiator's public key. If this is done now, the
1803 man in the middle will get caught. Updated the protocol
1806 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Better installation directory handling. Configure module
1809 paths and other paths automatically to example_silc* files
1810 in doc/. A patch by toma.
1812 * Fixed compiler warning from MPI library, and from SILC RNG.
1815 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1816 It can be configured with ./configure. A patch by toma.
1818 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Find correct make to use in prepare-clean. A patch by
1821 toma. Affected file prepare-clean.
1823 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1825 * Added irssi variables use_auto_addr, auto_bind_ip,
1826 auto_bind_port and auto_public_ip.
1828 * Changed the interface for silc_client_send_key_agreement
1829 in lib/silcclient/silcapi.h
1833 irssi/src/silc/core/silc-core.c
1835 lib/silcclient/silcapi.h
1836 irssi/src/silc/core/silc-channels.c
1837 lib/silcclient/client_keyagr.c
1840 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Added silc_pkcs_public_key_compare to compare two
1843 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1845 * Check that the client who set the founder mode on the
1846 channel is the same client that is giving the founder
1847 mode to itself. It is done by comparing the saved public
1848 key (it is saved even in the authentication is passphrase).
1849 Affected file silcd/command.c.
1851 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Do not process packet for disconnected socket connection.
1854 Affected file lib/silccore/silcpacket.c.
1856 * Process the DISCONNECT packet through scheduler in the
1857 client library. Affected file lib/silcclient/client.c.
1859 * Fixed the silc_client_packet_parse to not to increase
1860 the packet sequence number if the conn->sock and the
1861 current socket connection is not same. This can happen
1862 for example during key agreement when the conn includes
1863 multiple socket connections (listeners). Affected file
1864 lib/silcclient/client.c.
1866 * The sender of the file transfer request now provides also
1867 the pointer (listener) for the key exchange protocol. If
1868 the listener cannot be created then it sends empty key
1869 agreement and lets the receiver provide the listener.
1871 Added `local_ip' and `local_port' arguments to the
1872 silc_client_file_send. If they are provided they are used,
1873 if not then it will attempt to find local IP address, if
1874 not found or bind fails then the remote client will provide
1877 Affected files are lib/silcclient/client_ftp.c and
1878 lib/silcclient/silcapi.h.
1880 * Extended the FILE SEND command to support defining the
1881 local IP and port for key exchange listener. They are
1882 optional. Affected file irssi/src/silc/core/silc-servers.c.
1884 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Defined to WHOIS command reply the sending of fingerprint
1887 of the client's public key (if the proof of posession of the
1888 corresponding private key is verified by the server).
1889 Updated to the protocol specification.
1891 * Added support of receiving the client's public key's
1892 fingerprint in command reply in client library. Affected
1893 file is lib/silcclient/command_reply.c, and
1894 lib/silcclient/idlist.[ch].
1896 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1898 * Do not send over 128 chars long nickname to the server
1899 in NICK command. Affected file lib/silcclient/command.c.
1901 * Do not send over 256 chars long channel names to the server
1902 in JOIN command. Affected file lib/silcclient/command.c.
1904 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Assure that silc_server_close_connection cannot be called
1907 twice for same socket context. Affected file is
1910 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Send error message to application if opening file for
1913 writing during file transfer fails. Affected file is
1914 lib/silcclient/client_ftp.c.
1916 Remove all file transfer sessions for a client that we're
1917 removing from ID cache.
1919 Affected file is lib/silcclient/client_ftp.c.
1921 * Fixed silc_net_addr2bin to return correct address. Affected
1922 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1924 * Fixed file transfer session removing on signoff notify.
1925 Affected file irssi/src/silc/core/silc-servers.c.
1927 * Added the SilcClientFileError to be returned in the monitor
1928 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1929 Affected file lib/silcclient/silcapi.h.
1931 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Fixed a crash in silc_client_ftp_free_sessions and
1934 silc_client_ftp_session_free_client. Affected file
1935 lib/silcclient/client_ftp.c.
1937 * Added `disabled' field in the SilcChannelEntry in the server
1938 to indicate if the server entry is disabled. Affected file
1939 silcd/idlist.h, silcd/command[_reply].c.

1948 * Fixed a crash in client resolving in client_prvmsg.c in
1949 client library. Affected file lib/silcclient/client_prvmsg.c.
1951 * Do not actually remove the client directly from ID cache
1952 during SERVER_SIGNOFF, but invalidate it. This way we
1953 preserve the WHOWAS info for the client. Affected file
1954 silcd/server_util.c.
1956 * Fixed SERVER_SIGNOFF notify handling in the server. The
1957 server is now able to process incoming SERVER_SIGNOFF notify
1958 for a server that it doesn't even know about. It will remove
1959 the clients provided in the notify. Affected file
1960 silcd/packet_receive.c.
1962 * Check for partial packet in data queue after every packet that
1963 was found from the queue. Return and wait for more data if
1964 there is partial data in queue. Affected file is
1965 lib/silccore/silcpacket.c.
1967 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1972 Affected files lib/silcclient/silcapi.h and
1973 lib/silcclient/client_ftp.c.
1975 * Check that newsize in silc_buffer_realloc is larger than
1976 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1978 * Added better monitor of file transfers. It now monitors
1979 key agreement protocol during the file transfer too. Added
1980 error reporting too. Affected files

1982 irssi/src/fe-common/silc/module-formats.[ch].
1984 * Wrote a help file for FILE command.
1986 * Added silc_rng_global_get_byte_fast to get not-so-secure
1987 random data as fast as possible. Random data is read from
1988 /dev/urandom if available and from the SILC RNG if not
1989 available. It is used in padding generation. Affected file
1990 lib/silccrypt/silcrng.[ch].
1992 * All packets in client library are now processed synchronously.
1993 Optimized packet processing a lot. Affected file
1994 lib/silcclient/client.c.
1996 * All server connection packets are processing synchronously
1997 now in server, to optimize packet processing. Affected file
2000 * Include files are installed now only in Toolkit distribution
2001 if make install is given. Affected files: all Makefile.am's.
2003 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2005 * Assure that silc_client_notify_by_server_resolve does not
2006 resolve the client information multiple times. If it cannot
2007 be found by the first it cannot be found at all. Affected
2008 file lib/silcclient/client_notify.c.
2010 * Fixed WHOWAS command reply calling. Affected file
2011 lib/silcclient/command_reply.c.
2013 * Removed all references to silc_idlist_get_client from the
2014 Irssi SILC client since that call is internal call used by
2015 the library. The Irssi SILC client will use now client
2016 retrieval functions found in silcapi.h.
2018 * Fixed a bug in resolving nickname info before sending
2019 private message. It used freed memory. Affected file
2020 irssi/src/silc/core/silc-servers.c.
2022 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2024 * Assure my_channels statistics cannot go negative in server.
2025 Affected files silcd/server.c, silcd/server_util.c.
2027 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2041 * Added silc_net_localip to return local host's IP address.
2042 Affected file lib/silcutil/silcnet.[ch].
2044 * If key exchange or rekey protocol is active for a connection
2045 parse all packets syncronously since there might be packets
2046 in packet queue that we are not able to process without first
2047 processing packets before them. Affected file silcd/server,
2048 lib/silcclient/client.c.
2050 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2051 whether library should continue processing the packet.
2052 Affected file lib/silccore/silcpacket.h.

2125 * Call the silc_server_udpate_servers_by_server in the
2126 primary router that comes back online in the backup resuming
2127 protocol. Otherwise it routes packets wrong. Affected file
2128 silcd/server_util.[ch], silcd/server_backup.c.
2130 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2132 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2133 lib/silcutil/silcbuffmt.[ch].
2135 * Redefined the SILC packet header to include the padding
2136 length. Affected file lib/silccore/silcpacket.[ch].
2138 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2139 length for maximum padding up to 128 bytes). Affected
2140 file lib/silccore/silcpacket.h.
2142 * Removed all backwards support for old 0.5.x MAC thingies.
2143 The SILC packet header change makes it impossible to be
2144 backwards compatible.
2146 * Send the ENDING packet with timeout in the backup resuming
2147 protocol. This is to assure that all routers has connected
2148 to the primary router. Affected file silcd/server_backup.c.
2150 * Changed the RNG to take the first IV from random data. It
2151 used to take it from zero actually. Changed the RNG also
2152 to use /dev/urandom during session. /dev/random is used
2153 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2155 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * Changed the SILC packet header to have the first two bytes
2158 (the packet length) encrypted. Affected files aroung the
2159 code tree, lib/silccore/silcpacket.[ch]. Removed the
2160 SilcPacketCheckDecrypt callback. It is not needed anymore
2161 since the silc_packet_receive_process will determine now
2162 whether the packet is normal or special.
2164 * Implemented the unidirectional MAC keys. Affected files
2165 lib/silcske/silcske.c, silcd/protocol.c and
2166 lib/silcclient/protocol.c.
2168 * Implemented the packet sequence number to the MAC computation.
2169 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2170 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2171 lib/silcclient/protocol.c.
2173 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Allow backup router to announce servers. All servers
2176 announced by backup router are added to the global list
2177 automatically. Update hte server's socket to our primary
2178 router also when backup router announces a server.
2179 Affected file silcd/packet_receive.c.
2181 * Do not update the client->router in the function
2182 silc_server_udpate_clients_by_server if the client is on
2183 global list. We might fail to find any specific server
2184 for locally connected clients and local cell clients. They
2185 should still use the `from' and not `to' as client->router.
2186 This fixes backup router resuming protocol. Affected file
2187 silcd/server_util.c.
2189 * Decrease channel statistics count only if the channel
2190 deletion worked. Affected files are silcd/server.c and
2191 silcd/server_util.c.
2193 * Added silc_server_update_servers_by_server to update origin
2194 of all server entries. Used during backup router protocol.
2195 Affected files silcd/server_util.[ch], silcd/server.c. and
2196 silcd/backup_router.c.
2198 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2199 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2200 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2201 lib/silccrypt/silchmac.c.
2203 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2205 * Assure that router cannot reroute the same channel message
2206 to the sender. Affected file silcd/packet_receive.c.
2208 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Made better checks that the channel message is not sent
2211 to the router it came from. Affected file is
2212 silcd/packet_send.c. Fixed memory leak too.
2214 * Announce informations for incoming router connection, but
2215 only after checking if it is replaced by backup router.
2216 Affected file silcd/packet_receive.c.
2218 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2220 * Fixed the backup resuming protocol to work in multiple
2221 router environment. Affected file silcd/server_backup.c.
2223 * Route packet only to one router in the function
2224 silc_server_packet_send_to_channel. Affected file is
2225 silcd/packet_send.c.
2227 * Fixed silc_server_send_notify_dest to set the broadcast
2228 flag. Fixed the silc_server_send_notify_topic to actually
2229 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2230 Affected file silcd/packet_send.c.
2232 * Changed the SFTP Filesystem interface. Changed the
2233 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2234 the filesystem operation function. The SilcSFTPFilesystem
2235 is now a context that is allocated by all filesystem allocation
2236 functions and it already includes the operations structure
2237 and filesystem specific context. It is given as argument
2238 now to the silc_sftp_server_start. This made the interface
2239 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2240 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2242 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Changed the backup router adding and getting interfaces
2245 in the server. The router that will be replaced by the
2246 specified backup router is now sent as argument. Affected
2247 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2250 * Added silc_net_addr2bin_ne to return the binary form of
2251 the IP address in network byte order. Affected files
2252 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2254 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Check for existing server ID in silc_server_new_server
2257 and in silc_server_connect_to_router_final and remove the
2258 old entry if it exists. Affected file silcd/packet_receive.c,
2261 * Send the channel message always to only one router, either
2262 in upstream or downstream. Affected file is
2263 silcd/packet_send.c.
2265 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Wrote the definition of the backup resuming protocol to the
2268 protocol specification.
2270 * Removed one redundant channel key generation from normal
2271 server during joining procedure. Removed one redundant
2272 channel key sending from server to router during joining
2273 procedure. Affected file silcd/command.c.
2275 * Made minor bugfixes to the backup router resuming protocol.
2276 Affected file silcd/server_backup.c, server.c.
2278 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Added --disable-asm configuration option. Affected files
2281 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2284 * Implemented the backup resuming protocol that is used to
2285 resume the primary router position in the cell after the
2286 primary router comes back online. Affected files
2287 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2288 and silcd/server_util.[ch].
2290 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Sleep two (2) seconds after sending QUIT command to server.
2293 Affected file lib/silcclient/command.c.
2295 * Assure that if outgoing data buffer is pending do not force
2296 send any data. Affected file silcd/packet_send.c.
2298 * Assure that if outgoing data buffer is pending do not force
2299 send any data. Affected file lib/silcclient/client.c.
2301 * Implemented the backup router support when the primary router
2302 goes down. The servers and routers can now use the backup
2303 router as new primary router without loosing connectivity.
2305 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2307 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2308 in the server to indicate disabled entry. All data read
2309 from the connection will be ignored and no data is sent
2310 for entry that is disabled. Affected files are
2311 silcd/idlist.h, silcd/server.c.
2313 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Created SFTP client and server test programs in the
2316 lib/silcsftp/tests directory.
2318 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Implemented memory filesystem (virtual filesystem) for
2321 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2324 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Implemented the SFTP (SSH File Transfer Protocol) to the
2327 lib/silcsftp. It includes SFTP client and SFTP server
2330 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Moved lib/silccore/silcprotocol.[ch] to the
2333 lib/silcutil library.
2335 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2336 take variable argument list pointer as argument. Affected
2337 file lib/silcutil/silcbuffmt.[ch].
2339 * Added silc_buffer_set function that is used to set data
2340 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2341 Affected file lib/silcutil/silcbuffer.h.
2343 * Changed various routines in the core library to use the new
2344 silc_buffer_set instead of allocating new buffer only for
2347 * Added 64-bit value formatting and unformatting support to the
2348 silc_buffer_[un]format routines. Affected file is
2349 lib/silcutil/silcbuffmt.[ch].
2351 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2352 to includes/bitmove.h.
2354 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Fixed channel user mode saving in client library. Affected
2357 file lib/silcclient/command[_reply].c.
2359 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * Defined the file transfer to the SILC Protocol. Added
2362 new packet type SILC_PACKET_FTP and defined File Transfer
2363 Payload. The mandatory file transfer protocol is SFTP
2364 (SSH File Transfer Protocol). Affected file in addition
2365 of the internet draft is lib/silccore/silcpacket.h.
2367 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2368 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2369 is used as part of backup router protocol when the primary
2370 router of the cell is back online and wishes to resume
2371 the position as primary router.
2373 * Redefined the MAC generation keys in the protocol. The
2374 same key is not used anymore in both direction. Both
2375 direction will now use different keys for sending and
2376 receiving. This fixes a potential security flaw. This
2377 change causes incompatibilities in the protocol.
2379 * Redefined also the MAC computation from the packet.
2380 An packet sequence number is now added to the MAC
2381 computation. This prevents possible replay attacks against
2382 the protocol. This change too causes incompatibilities
2385 Added `sequence' field to the SilcPacketContext to hold
2386 the current sequence number for the packet.
2388 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Added `created' field to the SilcIDListData in the file
2391 silcd/idlist.h to indicate the time when the entry was
2394 * Added `created' field to the SilcChannelEntry too. Affected
2395 file silcd/idlist.h.
2397 * Added `creation_time' aguments to all the announcement functions
2398 in the server. If it is provided then only the entries that
2399 was created after the provided time frame are actually
2400 announced. Affected file silcd/server.[ch].
2402 * The protocol says that the Channel ID's IP address must be
2403 based on the router's IP address. Added check for this in
2404 the silc_server_new_channel when processing incoming New Channel
2405 Payload. Affected file silcd/packet_receive.c.
2407 * Print out the correct version with --version in SILC client.
2408 Affected file irssi/src/silc/core/silc-core.c.
2410 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2412 * Fixed WHOWAS command to check for completnes of the client
2413 entry always, not just when the command is coming from client.
2414 Affected file silcd/command.c.
2416 * Added new function silc_server_packet_queue_purge to purge the
2417 outgoing data queue to the network. After the function returns
2418 it is guaranteed that the outgoing packet queue is empty.
2419 Affected file silcd/packet_send.[ch].
2421 * Purge the outgoing packet queue in the rekey protocol's final
2422 callback to assure that all rekey packets go to the network
2423 before quitting the protocol. Affected file silcd/server.c.
2425 * Added silc_client_packet_queue_parse as similar function as
2426 in server to the client library. The affected file is
2427 lib/silcclient/client.c.
2429 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Splitted silcd/server.c and created silcd/server_util.[ch]
2432 for utility functions.
2434 * Added new socket flag SILC_SF_DISABLED to indicate that the
2435 connection is open but nothing can be sent to or received from
2436 the connection. Affected file lib/silcutil/silsockconn.[ch].
2437 The checking for disabled socket is checked in the low level
2438 silc_socket_write and silc_socket_read functions.
2440 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Allow only nicknames and channel names that fits into the
2443 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2445 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * When processing JOIN command reply in server check that if
2448 the channel exists in our global list we'll move it the local
2449 list. Affected file silcd/command_reply.c.
2451 * Fixed the check whether client is joined on the channel already
2452 in JOIN command. Affected file lib/silcclient/command.c.
2454 * Fixed the JOIN command reply to check whether the channel
2455 already exists. Affected file lib/silcclient/command_reply.c.
2457 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Added silc_ske_status_string to map the SKE error numbers
2460 to readable strings. The affected files are
2461 lib/silcske/silcske[_status].[ch].
2463 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Do not show the private channels on the WHOIS channel list
2466 as it is not allowed by the protocol. The affected file is
2469 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Assure that the packet length digged from the actual packet
2472 is something sensible in the silc_packet_decrypt_rest_special
2473 in lib/silccrypt/silcpacket.c.
2475 * Free and NULL the allocated pointer in silc_hmac_alloc if
2476 the HMAC allocation fails. The affected file is
2477 lib/silccrypt/silchmac.c.
2479 * Print the selected security properties to the log files in
2480 the server. Affected file silcd/protocol.c.
2482 * Add SKE's reference counter even if calling the completion
2483 callback manually. Otherwise it goes negative, although it
2484 does not cause any problems. The affected file is
2485 lib/silcske/silcske.c.
2487 * Remove the client entry with short timeout after giving the
2488 KILL command. Affected file lib/silcclient/command.c.
2490 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2491 case all found clients are already disconnected (WHOWAS would
2492 found them) in the server. Affected file silcd/command.c.
2494 * Update the last_receive (time of last data received) to be
2495 updated only when received private or channel message so that
2496 the idle time showed in WHOIS makes more sense.
2498 * Added boolean field `valid' in to the SilcClientEntry in the
2499 client library to indicate whether the entry is valid or not.
2500 This fixes the nickname change bug on channel when changing
2501 the nickname to be same than the old (like nick to Nick) the
2502 nickname formatter doesn't set the new nick anymore to Nick@host.
2503 Affected file lib/silcclient/idlist.[ch].
2505 * Now actually fixed the nickname changing on disconnection.
2506 Added new function silc_change_nick to the Irssi SILC Client.
2507 Affected file irssi/src/silc/core/client_ops.c,
2508 irssi/src/silc/core/silc-nicklist.[ch].
2510 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Check that the public key exists in the GETKEY command before
2513 trying to encode it. Affected file silcd/command.c.
2515 * Print some notifications on received public keys with GETKEY
2516 command in the Irssi SILC Client. Affected files are
2517 irssi/src/fe-common/silc/module-formats.[ch],
2518 irssi/src/silc/core/client_ops.c.
2520 * Use IDENTIFY command to resolve the server information in the
2521 GETKEY command instead of INFO command. Affected file
2522 lib/silcclient/command.c.
2524 * All command reply functions in the client library now calls
2525 the pending command reply callbacks even if an error has
2526 occurred. The server has done this a long time and now it was
2527 time to move the client library to this as well. Now all
2528 errors can be delivered back to the pending command reply
2529 callbacks if necessary. Affected files are
2530 lib/silcclient/command[_reply].[ch].
2532 * Change the nickname on disconnection back to the username
2533 because in reconnect the server will enforce it to it anyway.
2534 Affected file irssi/src/silc/core/silc-servers.c.
2536 * Fixed a config file parsing bug in the Irssi SILC client.
2537 Affected file irssi/src/silc/core/clientconfig.c.
2539 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * When printing the channel mode on JOIN, verify that the
2542 channel key and channel's HMAC are valid. Affected file
2543 irssi/src/silc/core/client_ops.c.
2545 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2548 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2549 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2551 * Removed channel key rekey task deleting from the function
2552 silc_server_save_channel_key. Affected file silcd/server.c.
2553 Added explicit timeout task context instead that is used to
2554 delete the task if we are registering a new task before the
2555 new task has elapsed.
2557 * When channel key rekey occurs the client library now saves
2558 the old channel key for a short period of time (10 seconds) and
2559 is able to use it in case some is still sending channel
2560 messages encrypted with the old key after the rekey. Affected
2561 file lib/silcclient/[idlist.h|client_channel.c].
2563 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Added check to the silc_server_new_id_real to not accept
2566 new ID if it is the sender's own ID. Affected file is
2567 silcd/packet_receive.c.
2569 * Assure that we do not announce ourself or the one we've
2570 sending our announcements when we're router and are announcing
2571 servers to our primary router. Affected file silcd/server.c.
2573 * Fixed silc_server_command_identify_check_client to assemble
2574 correct WHOIS packet. It send corrupted WHOIS packet and
2575 caused problem with router to router connections. Affected
2576 file silcd/command.c.
2578 Fixed also silc_server_command_whois_check the same way
2579 as for the IDENTIFY command.
2581 * Added new SilcIDListStatus to the server in the SilcIDListData
2582 structure. The status now includes the current status of
2583 the entry (like registered, resolved etc.). Affected file
2584 silcd/idlist.[ch]. Defined a bunch of different status types
2585 as well. This replaced the old boolean registered field as well.
2587 Added resolve_cmd_ident field to the SilcClientEntry structure
2588 too so that if the entry is for example being resolved so
2589 another command may attach to the same pending command reply
2590 without requiring to resolve the same entry again. This concept
2591 should optimize the WHOIS and the IDENTIFY resolving under
2592 heavy load by taking away unnecessary resolving for entries
2593 that are being resolved already.
2595 Added support for adding multiple pending commands for one
2596 command idenfier. Affected file silcd/command[_reply].[ch].
2598 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2599 before deleting the data. Otherwise the hash table will have
2600 freed data in comparison functions. Affected file is
2601 silcd/command_reply.c.
2603 * Fixed silc_idlist_replace_client_id to add the new entry to
2604 the cache with NULL nickname. Otherwise there will be invalid
2605 memory as the nickname after the nickname is freed. Affected
2606 file silcd/packet_receive.c.
2608 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2609 saved into wrong slots because the previous number of entries
2610 was not taken into account. Affected file silcd/idlist.c.
2611 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2613 * If we are router and we receive JOIN notify to a channel that
2614 does not have any users then notified client is marked as the
2615 channel founder, as it is it. The affected file is
2616 silcd/packet_receive.c
2618 * Added to the extended hash table API's table_del_*ext functions
2619 the destructor as argument too, so that the caller can decide
2620 which destructor to use or whether to use destructor at all.
2621 Affected file lib/silcutil/silchashtable.[ch].
2623 * Fixed ID Cache purging. It actually deleted the entries from
2624 the hash table after the data was freed. The hash table ended
2625 up comparing freed memory. The affected file is
2626 lib/silccore/silcidcache.c.
2628 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Fixed Irssi SILC client's KILL command's HELP syntax.
2632 * The USERS command now resolves the detailed user information
2633 if the userinfo field is missing. Affected file is
2634 lib/silcclient/command_reply.c.
2636 * Do not print error in silc_file_read if the read file does
2637 not exist. Just silently return NULL. Affected file is
2638 lib/silcutil/silcutil.c.
2640 * Fixed the silc_log_output to not wine about NULL filename
2641 and to not create some bogus " " filename. Affected file is
2642 lib/silcutil/silclog.c.
2644 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Fixed various printing bugs on the user interface in the
2647 Irssi SILC Client. Minor changes that were forgotten from
2650 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Fixed the configure.in.pre and the compilation and distribution
2653 environment to support the new autoconf 2.52. That version is
2654 now required to compile the CVS trunk.
2656 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2658 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2659 to generally parse user@fqdn format strings. Affected file
2660 lib/silcutil/silcutil.c.
2662 * Added nickname_format and nickname_force_format fields to the
2663 SilcClientParams structure. The first one defines the format
2664 for the nicknames that the library will enforce if the receives
2665 multiple same nicknames. The second one is boolean value and
2666 can be used to force the library to always enforce the format
2667 to the nicknames regardles whether there are multiple nicknames
2668 or not. This configurable formatting was employed to flexibly
2669 support accessing multiple nicknames from the user interface.
2670 The userinterface can now set the nicknames to what ever format
2671 they prefer. Affected file lib/silcclient/silcapi.h.
2673 Added function silc_client_nickname_format to the file
2674 lib/silcclient/idlist.c. It performs the nickname formatting.
2676 Added new field `hostname´ to the SilcClientEntry context.
2677 It holds the hostname of the client. Affected file is
2678 lib/silcclient/idlist.h.
2680 * Irssi SILC Client sets the nicknames in nick@hostn format.
2681 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2682 irssi/src/silc/core/silc-core.c.
2684 The WHOIS printing now also shows both the real nickname and
2685 the formatted nickname so that user knows how to access the
2686 user if there are multiple same nicknames cached. Affected
2687 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2688 printing formatting too to take the hostname now as a separate
2689 argument. The Affected file is
2690 irssi/src/fe-common/silc/modules-formats.[ch].
2692 * Changed the silc_client_get_clients_local to accept the formatted
2693 nickname as argument. It accepts the real nickname too but the
2694 formatted nickname can be used to find the true entry from
2695 multiple entries. Affected file lib/silcclient/silcapi.h and
2696 lib/silcclient/idlist.c.
2698 * Added nickname_format_parse field to the SilcClientParams.
2699 It is a callback function provided by the application to parse
2700 the nickname out of the formatted nickname string. The library
2701 calls it to get the nickname from the formatted string. Since
2702 the application generally knows better the format of the nickname
2703 string it parses it instead of the library, even though library
2704 encodes the formatted string. If the callback function is not
2705 provided then the library will use the string as is. The
2706 affected file is lib/silcclient/silcapi.h.
2708 * All the nickname strings passed to the client library in
2709 commands are now expected to be formatted nickname strings.
2710 If the command does not support the formatted nickname string
2711 it will assume that the sent string is the actual nickname.
2712 Affected file lib/silcclient/command.c.
2714 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Added public key authentication support to OPER and SILCOPER
2717 commands in the client library. Affected file is
2718 lib/silcclient/command.c.
2720 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Changed the get_auth_methdod client operation to be asynchronous.
2723 It can be async if the application resolves the authentication
2724 method from the server during the negotiation. Added new
2725 SilcGetAuthMeth completion callback that the application will
2726 call after resolving the authentication method.
2728 Added function silc_client_request_authentication_method that
2729 the application can use to resolve the authentication method
2730 from the server. Added also SilcConnectionAuthRequest callback
2731 that the library will call after the server has replied. The
2732 application can call this function if it does not know the
2733 current authentication method.
2735 Affected files are lib/silcclient/client.c and
2736 lib/silcclient/silcapi.h.
2738 * The Irssi SILC client now automatically resolves the authentication
2739 method incase any configuration information is not present (and
2740 currently there never is). The affected file is
2741 irssi/src/silc/core/client_ops.c.
2743 * Fixed public key authentication from the client library.
2744 Affected file lib/silcclient/protocol.c. Changed also the
2745 protocol specification about the public key authentication in
2746 the connection authentication protocol. The actual data to be
2747 signed is now computed with a hash function before signing.
2749 * Fixed the public key authentication from the server as well.
2750 Affected file silcd/protocol.c.
2752 * Removed the mlock()'s from the memory allocation routines.
2753 Affected file lib/silcutil/silcmemory.c. The ./configure does
2754 not check anymore for the mlock(). Affected file is
2757 * Fixed USERS command in server to allow the execution of the
2758 command for private and secret channels if the client sending
2759 the command is on the channel. Affected file silcd/command.c.
2761 * Fixed silc_client_get_clients_local to return the clients
2762 count correctly. It could return wrong value. Affected file
2763 lib/silcclient/idlist.c.
2765 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2768 types. The assembler optimizations seemed not to like 64-bit
2769 data types. The assmebler optimizations thus are now enabled
2770 also for BSD systems as opposed to only enable them for Linux.
2772 * Do not check for threads at all on BSD systems. Affected
2773 file configure.in.pre.
2775 * Removed -n and -h options from the Irssi SILC Client since
2776 they are not used in silc.
2778 * Fixed the prime generation to assure that the first digit
2779 of the generated random number is not zero since our conversion
2780 routines does not like number strings that starts with zero
2781 digit. If zero digit is seen the random number is regenerated.
2782 This caused some corrupted RSA keys when the zero first digit
2783 was met. Affected file lib/silcmath/silcprimegen.c.
2785 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Fixed WIN32 configuration in the ./configure script.
2788 Fixed to include xti.h on environments that has it.
2789 Patches by Carsten Ilchmann and andrew.
2791 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * Changed the silc_id_create_client_id to be collision
2794 resistant. It is now assured that there cannot be created
2795 two same client ID's. I suspect that some weird bugs in
2796 the server were actually caused by duplicate Client IDs.
2797 Affected file silcd/serverid.[ch]. A router receiving
2798 new ID now also assures and informs the sending server
2799 if the ID caused collision.
2801 * Changed the silc_id_create_channel_id to also assure that
2802 there are no collisions.
2804 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2806 * Statement about ignoring the Mutual Authentication flag when
2807 performing rekey with PFS was a bit misleading. It is ignored
2808 if it was set in the initial negotiation, it cannot be even
2809 set in the rekey. Fixed in the ke-auth draft. Started the
2810 new versions of the protocol drafts in the doc/.
2812 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Fixed a bug in silc_client_command_identify_save when saving
2815 new channel information. The channel name was no duplicated
2816 and caused crash on exit. Affected file is
2817 lib/silcclient/command_reply.c.
2819 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Fixed the getkey command handling in the server. Send just
2822 empty OK reply to the sender if the key could not be fetched
2823 (but everything else was ok, like the key just was not available).
2824 Changed the public key parameter to optional in the protocol
2825 specs so that empty OK reply can be sent. Affected file
2828 Added a message to Irssi SILC client to tell to user if the
2829 server did not return a public key.
2831 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Fixed a channel key regeneration bug. It registered new
2834 timeout tasks exponentially until all system resources were
2835 used. Affected file silcd/server.c.
2837 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Added the SILC Document generator to the scripts/silcdoc.
2840 It can be used to generate the Toolkit Reference Manual out
2841 of the source tree. Internally it will also use the RoboDoc
2842 generator now imported in util/robodoc.
2844 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Added couple of return's in rekey protocol if error orccurred
2847 during the protocol. The execution must be terminated.
2848 Affected file silcd/protocol.c. Also, terminate the protocol
2849 always with timeout.
2851 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * The client's Client ID was created initally from the wrong
2854 nickname (it could have been in format nick@host) in the
2855 silc_server_new_client. Affected file silcd/packet_receive.c
2857 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * Added some SILC_LOG_ERROR's to various error conditions
2860 if client could not be added to ID cache. Affected files
2861 silcd/packet_receive.c and silcd/server.c.
2863 * When client's sock->user_data is freed, NULL also the
2864 client->router and client->connection pointers. Added check
2865 for these pointers being NULL to various places around the
2866 code. Affected file silcd/server.c.
2868 * Added client->data.registered == TRUE checks to various
2869 places around the code to assure that unregistered client's
2870 are not handled when it is not allowed. Affected file
2873 * Added `bool registered' fields to all
2874 silc_idlist_[server|client]_get_* routines to indicate whether
2875 the fetched client needs to be registered or not. Affected
2876 file silcd/idlist.[ch].
2878 * Add your own entry as registered to the ID cache in the
2879 server. Affected file server.c.
2881 * Fixed a bug in silc_server_new_server. The SilcServer was
2882 set as the new server's context instead of SilcServerEntry.
2883 This naturally caused some weird bugs.
2885 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Do not delete the channel rekey task when adding it
2888 for in silc_server_create_channel_key.
2890 * Changed the silc_server_create_channel_key to return
2891 TRUE or FALSE to indicate the success of the channel key
2894 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Fixed MSVC++ project files and added missing files to
2897 Makefiles under win32/.
2899 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Do not add TCP_NODELAY flag if the operating system
2902 does not have it defined. Affected files are
2903 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2905 * Fixed buffer overflow from Irssi SILC Client. Affected
2906 file irssi/src/fe-common/core/themes.c.
2908 * Fixed double free in client library in the file
2909 lib/silcclient/client.c when disconnecting from server.
2911 * Applied double free patch from cras to Irssi SILC client.
2912 Affected files irssi/src/core/[modules/expandos].c
2914 * Fixed the disconnection handling to Irssi SILC Client.
2915 The application must call silc_client_close_connection
2916 in ops->connect client operation in case of failure of
2917 the connection. Affected file is
2918 irssi/src/silc/core/client_ops.c.
2920 * Do not set sock->protocol to NULL in the function
2921 silc_client_close_connection after executing the protocol's
2922 final callback since the sock might not be valid anymore.
2923 Affected file lib/silcclient/client.c.
2925 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2927 * Do not enable SILC_THREADS if the linking with libpthread
2928 did not happen. Affected file configure.in.pre.
2930 * Added notion to protocol specification that server must
2931 verify the sent authentication payload with CMODE when
2932 setting the channel founder key. Implemented it to the
2933 server. Affected file silcd/command.c.
2935 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Added _EXTRA_DIST SILC distribution variable to the
2938 distributions file. It is used to conditionally add extra
2939 files or directories to the specific distribution. Affected
2940 files ./prepare, Makefile.am.pre and distributions.
2942 Removed the `_' from the start of the distribution names.
2945 * Added README.WIN32 for instructions to compile the Toolkit
2948 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Fixed a double free in disconnection in the server. Affected
2951 file is silcd/server.c.
2953 * Fixed the lib/silcske/groups.c to work now also with GMP
2954 MP library. The string conversion did not work when using
2955 specific base and the base is indicated in the string as well.
2957 * Created win32/ directory which now includes MSVC++ specific
2958 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2959 It will appear only in the toolkit distribution
2961 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Changed the key material distribution function in case when
2964 the hash output is too short. The data is now concatenated
2965 a bit differently than it used to. Made the change to the
2966 SKE protocol specification.
2968 * Added better GMP detection to configure.in.pre. A patch
2971 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Fixed a minor bug in SKE that might cause some problem on
2974 some platforms. Affected file lib/silcske/silcske.c.
2976 * Added the cookie checking for initiator in the SKE. It checks
2977 that the responder returns the sent cookie unmodified. The
2978 affected file is lib/silcske/silcske.c. Added new SKE
2979 error type INVALID_COOKIE that can be sent during the
2980 negotiation. Fixed some memory leaks as well.
2982 * Added the "invalid cookie" error message to Irssi SILC client's
2985 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Added `task_max' field to the SilcClientParams to indicate
2988 the maximum tasks the scheduler can handle. If set to zero,
2989 default values are used. Affected file lib/silcclient/silcapi.h.
2991 * Fixed memory leaks in silc_client_close_connection. Affected
2992 file lib/silcclient/client.c.
2994 * Added silc_client_del_client_entry to client library to free
2995 all memory of given client entry. Affected file is
2996 lib/silcclient/idlist.[ch].
2998 * Added new functions silc_client_del_channel and
2999 silc_client_del_server to delete channel and server entries.
3000 Affected file lib/silcclient/[silcapi.h/idlist.c].
3002 * Removed silc_client_del_client_by_id from silcapi.h.
3004 * Fixed the INFO command to return the server's own info
3005 correctly when querying by Server ID. Affected file is
3008 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Removed the non-blocking settings in WIN32 code in the
3011 silc_sock_[read/write] and added SleepEx instead. Affected
3012 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3013 of input data is now checked with FIONREAD and ioctlsocket.
3015 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Call silc_schedule_task_del_by_context in the
3018 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3019 Affected file lib/silccore/silcprotocol.c.
3021 * Call silc_protocol_cancel for active protocols in the
3022 silc_server_close_connection if the funtion
3023 silc_server_free_sock_user_data has not been called.
3024 Affected file silcd/server.c.
3026 * Generic tasks cannot be deleted using the del_by_fd
3027 task deleting function since generic tasks does not match
3028 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3030 * Added a notion to SILCOPER help file that the SILCOPER works
3031 only on router server, not on normal server.
3033 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3035 * Added for WIN32 support for the new scheduler as well.
3036 Affected file lib/silcutil/win32/silcwin32schedule.c.
3038 * Fixed the SHA1 implementation to work on various platforms.
3040 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3043 API. It is part of the scheduler now. Everything else is
3044 as previously but some functions has changed their names.
3045 Checkout the lib/silcutil/silcschedule.h for the interface.
3046 Updated all applications to use the new interface. Affected
3047 files are lib/silcutil/silcschedule.[ch].
3049 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Found a bug in the SKE implementation. The HASH value,
3052 specified by the protocol, was not computed correctly. The
3053 public key of the responder was not added to the computation
3054 even though it is mandatory. Affected file lib/silcske/silcske.c.
3055 This unfortunately causes incompatibilities with older
3056 clients and servers.
3058 * Added WIN32 specific network init and uninit functions:
3059 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3060 the Winsock2. Affected file lib/silcutil/silcnet.h and
3061 lib/silcutil/win32/silcwin32net.c.
3063 * Set the socket always to nonblocking mode on WIN32 after
3064 reading data or writing data. Affected file is
3065 lib/silcutil/win32/silcwin32sockconn.c.
3067 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Fixed various compilation problems under WIN32. Affected
3070 files lib/silcutil/win32/silcwin32thread.c and
3071 lib/silcutil/win32/silcwin32schedule.c.
3073 * Removed all _internal.h #includes from public header
3074 files. Internal headers must never be included from
3077 Removed also the lib/silcske/payload_internal.h file.
3079 * All include files that may be needed (public and some others
3080 included by the public headers) by application developers are
3081 now copied to the ./includes directory. It does not copy any
3082 internal headers. Affected file Makefile.defines.pre and all
3083 Makefile.am's under lib/ and subdirs.
3085 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Do not change the ~/.silc directory's permissions automatically.
3088 Affected file irssi/src/silc/core/clientutil.c.
3090 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Do not cancel the protocol in silc_server_close_connection
3093 it might cause recursion. Now cancelled in the function
3094 silc_server_free_sock_user_data. Affected file silcd/server.c.
3096 * Fixed the silc_server_remove_clients_by_server to regenerate
3097 the channel keys correctly finally. Added also new function
3098 silc_server_remove_clients_channels to actually do it.
3099 Affected file silcd/server.c.
3101 * Fixed the silc_server_new_channel to not crash by giving
3102 wrong router to the new channel. Affected file is
3103 silcd/packet_receive.c.
3105 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3108 which is given as argument to the silc_client_alloc now.
3109 It can be used to configure the client and set various parameters
3110 that affect the function of the client.
3112 * The USERS command in server did not check whether the channel
3113 is private or secret. Affected file silcd/command.c.
3115 * Added new argument to the USERS command in protocol specification.
3116 The USERS command now can take the channel name as argument
3117 as well. Added support for this in client and server and
3118 updated the protocol specs.
3120 * Completed the GETKEY command in client. It can be now used
3121 to fetch also servers public key not only some clients.
3122 Affected files lib/silcclient/command[_reply].c.
3124 * Added silc_client_get_server to return server entry by the
3125 server name. Affected files lib/silcclient/silcapi.h and
3128 * Redefined the IDENTIFY command in protocol specification to be
3129 more generic. It now can be used to query information about
3130 any entity in the SILC Network, including clients, servers and
3131 channels. The query may be based either the entity's name
3132 or the ID. Added support for this in both client and server.
3134 Affected files silcd/command.c and lib/silcclient/command.c
3135 and command_reply.c.
3137 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3138 the _from_client and _from_server functions. Affected file
3141 * Added silc_client_get_channel_by_id_resolve to the file
3142 lib/silcclient/silcapi.h to resolve channel information by
3143 its ID. Added also silc_client_get_channel_by_id that
3144 does not resolve it from the server.
3146 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3148 * Added SilcServerEntry context into the client library
3149 to represent one server. The INFO command now allocates
3150 these to save the resolved server info. For now on the
3151 client library will also keep information about servers,
3152 connected and resolved with INFO.
3154 The INFO command now allocates the SilcServerEntry context
3155 and saves the server info there. The COMMAND_REPLY in
3156 the INFO now returns the parameters to application in
3157 same order as defined in the protocol specification.
3159 The entries are cached in the client->server_cache.
3161 * The INFO command is now issued after received the Client ID
3162 from the server. Affected file lib/silcclient/client.c.
3164 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3165 to the application as the mode changer might be server.
3166 It is guaranteed that NULL is not returned anymore to the
3167 application. Affected file lib/silcclient/client_notify.c.
3169 The ID Type is now also passed to the application so that
3170 it can check whether the returned entry is SilcClientEntry
3173 Added new function silc_client_get_server_by_id to return
3174 the server entry by ID. Affected files are the
3175 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3177 * Do not create the channel in the Irssi SILC Client when issuing
3178 the JOIN command but when received the sucessful JOIN command
3179 reply. Otherwise the channel might get created even though we
3180 could not join it. The Affected file is
3181 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3183 * Fixed a channel joining bug in router. The router must also
3184 check the channel modes, invite and ban lists etc. when serving
3185 the JOIN command sent by normal server. Affected file is
3186 silcd/command.c. The router now resolves the client's
3187 information from the server who sent the JOIN command if it
3188 does not know it, and processes the JOIN command only after
3191 * Changed the SilcCommandCb to take new argument; void *context2.
3192 Affected file lib/silccore/silccommand.h
3194 The second argument in the command callbacks in the server now
3195 includes the SilcServerCommandReplyContext if the command was
3196 called as pending command callback from the command reply.
3197 Otherwise it is NULL. When called as pending the status of the
3198 command reply will be checked and if it was erronous the
3199 error will be sent to the original sender of the command.
3200 This way the client always receives the error messages even
3201 though the server was actually the one who received the error
3202 when it resent the command to router, for example. Affected
3203 files silcd/command[_reply].[ch].
3205 * Fixed sending WHOWAS command's error message to client if
3206 the requested client could not be found. It was missing.
3209 * Changed the CMODE and CUMODE commands reply arguments in the
3210 protocol specification. The Channel ID is now sent in both
3211 of the commands to identify the channel. Implemented this
3212 new feature to the client and server. Affected files
3213 lib/silcclient/command_reply.c and silcd/command.c.
3215 * Made better checks for invite and ban lists in the JOIN
3216 command in server. Affected file silcd/command.c.
3218 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * The server now performs the incoming host IP/DNS lookup
3221 using the silc_socket_host_lookup and thus does not block
3222 the server anymore. Affected file silcd/server.c.
3224 * Completed the multi-thread support for SILC Scheduler in
3225 the lib/silcutil/silcschedule.c.
3227 * Fixed the configure.in.pre to detect the pthread correctly
3230 * Fixed a deadlock in silc_task_queue_wakeup in the file
3231 lib/silcutil/silctask.c.
3233 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Added new function silc_schedule_wakeup that is used in
3236 multi-threaded environment to wakeup the main thread's
3237 schduler. It needs to be used when a thread adds a new task
3238 or removes a task from task queues. After waking up, the
3239 scheduler will detect the task queue changes. If threads
3240 support is not compiled in this function has no effect.
3241 Implemented the wakeup mechanism to both Unix and WIN32
3242 systems. Affected files are lib/silcutil/silcschedule.[ch],
3243 lib/silcutil/unix/silcunixschedule.c and the
3244 lib/silcutil/win32/silcwin32schedule.c.
3246 * Added new function silc_task_queue_wakeup to wakeup the
3247 scheduler by the specified task queue. Affected file
3248 lib/silcutil/silctask.[ch].
3250 * The silc_socket_host_lookup_start now wakes up the scheduler
3251 after adding the timeout task. Affected file is
3252 lib/silcutil/silcsockconn.c.
3254 * The silc_socket_host_lookup is synchronous now if the threads
3255 support is not compiled in. However, the callback is still
3256 called asyncronously through the scheduler, anyway. Affected
3257 file lib/silcutil/silcsockconn.c.
3259 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3261 * Added new function silc_socket_host_lookup to perform
3262 asynchronous IP and FQDN lookups for the socket connection.
3263 Affected files lib/silcutil/silcsockconn.[ch].
3265 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3268 that may or may not compile the mutex support in.
3270 Changed the silc_mutex_alloc interface. It allocates the
3271 mutex now to the sent pointer and returns TRUE or FALSE.
3273 Affected file lib/silcutil/silcmutex.h.
3275 * Wrote the SILC Task Queue interface to support multi-threads.
3276 Affected file lib/silcutil/silctask.[ch].
3278 * Wrote the SILC Scheduler to support multi-threads. Affected
3279 file lib/silcutil/silcschedule.c.
3281 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3283 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3284 in lib/silcutil/win32/.
3286 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Defined SILC Mutex API and SILC Thread API and implemented
3289 them for Unix. Affected files are
3290 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3291 lib/silcutil/unix/silcunixmutex.c and
3292 lib/silcutil/unix/silcunixthread.c.
3294 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Fixed the silc_server_remove_clients_by_server's channel
3297 key re-generation. The hash table handling was incorrect
3298 and would not work with many channels. Affected file is
3301 * Fixed some memory leaks around the server code.
3303 * Rewrote the silc_server_get_users_on_channel to support IPv6
3304 based Client ID's. Affected file silcd/server.c.
3306 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3307 specification. However, a separate document must be written
3308 to define the detailed signing procedure and the payload
3309 associated with the flag. Defined the flag to the
3310 lib/silccore/silcchannel.h as well.
3312 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * Changed the dynamic tables to static size tables in the
3315 lib/silccrypt/silchmac.c.
3317 * Removed GCC dependencies from the code. A patch by cras.
3319 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Do not show the error "Error receiving packet bla bla"
3322 in server if it really was not an error (-2 means that reading
3323 is pending). Affected file silcd/server.c.
3325 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Fixed a possible crash in silc_server_remove_clients_by_server
3328 in silcd/server.c. Fixed there also some memory leaks.
3330 * Fixed the silc_idlist_replace_client_id. It could replace
3331 wrong key in the hash table. Affected file silcd/idlist.c.
3333 * Do not check whether there are global users on the channel
3334 if the channel->global_users is FALSE. Affected functions
3335 silc_server_remove_from_one_channel and
3336 silc_server_remove_from_channels in silcd/server.c. Also,
3337 do not check if the removed client is local as we can be
3338 sure that global client was not removed from the channel
3339 and checking for global users is not needed.
3341 * The silc_server_remove_clients_by_server now re-generates
3342 the channel keys correctly for those channels that had
3343 clients removed from them. Affected file silcd/server.c.
3345 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Found the reason of random crashes in the server. We weren't
3348 ignoring the SIGPIPE signal (which can be sent in write())
3349 and it crashed the server. Affected file silcd/silcd.c.
3351 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3353 * Assure that sock->user_data is not NULL in the function
3354 silc_server_packet_send in silcd/packet_send.c.
3356 * Disconnect the remote connection if it could not be added
3357 to any ID lists in the server. The affected file is
3360 * Check in silc_server_packet_send[_real/dest] that the
3361 socket is not disconnecting and ignore the data if it is.
3362 Affected file silcd/packet_send.c.
3364 * Define inline to __inline on native WIN32 compilation.
3365 Affected file includes/silcwin32.h.
3367 * Added some explicit type casts for inline code since MSVC
3368 require them. Affected files lib/silcutil/silcbuffer.h,
3369 lib/trq/silcdlist.h and lib/trq/silclist.h.
3371 * Print warning in log files from now on if the packet
3372 decryption fails. Affected file silcd/server.c.
3374 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3376 * Changed the `say' client operation's interface to accept
3377 new `type' argument to indicate the type of the message sent
3378 by the library. The application may filter the library's
3379 messages according the type. The affected file is the
3380 lib/silcclient/silcapi.h.
3382 * Added two new functions to lib/silcclient/silcapi.h:
3383 silc_client_del_client and silc_client_del_client_by_id.
3384 Affected file lib/silcclient/idlist.c.
3386 * Moved the clientincludes.h from includes/ to silc/ and
3387 serverincludes.h from includes/ to silcd/.
3389 * The modes for the CMODE and CUMODE are now passed as
3390 uint32 for application with COMMAND_REPLY. The affected
3391 file is lib/silcclient/command_reply.c.
3393 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * /WHOIS without arguments shows client's own information.
3396 Affected file lib/silcclient/command.c.
3398 * Changed PING to not accept any arguments. The specs
3399 says that client can ping only the connected server so
3400 requiring an argument is not needed. Affected file is
3401 lib/silcclient/command.c.
3403 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Fixed a fatal bug in private message sending and reception
3406 encryption and decryption when using private message keys.
3407 The implementation was incorrect and did not follow the
3408 specification. It causd that some of the message were
3409 lost since it did not use the sending and receiving keys
3410 as the protocol suggests. This has been fixed and will cause
3411 incompatibilities with older clients when sending private
3412 message encrypted with private message keys. Affected files
3413 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3414 and various other in Irssi SILC Client.
3416 Added `responder' boolean argument to the functions
3417 silc_client_add_private_message_key[_ske] to indicate when
3418 the key is added as responder or initiator of the key
3421 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Removed the silc_ske_check_version function and created
3424 a SilcSKECheckVersion callback. Added also a function
3425 silc_ske_set_callbacks that is now used to set all SKE
3426 callbacks. The callback functions are not given to
3427 the SKE functions anymore, but this function is used to
3430 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3432 * Added `silc_version' argument to the silc_client_alloc
3433 to define the version of the application for the library.
3434 The library will use the version string to compare it
3435 against the remote host's (usually a server) version
3436 string. Affected file lib/silcclient/silcapi.h
3438 * Added the KE protocol context to Key Agreement context
3439 in client library so that we can abort the SKE if it
3440 is in process when we get timeout. Affected file is
3441 lib/silcclient/client_keyagr.c.
3443 * Do not resolve the client ID forever if it returns in the
3444 first time that such client does not exist. This was done
3445 for example with private message. Affected file is
3446 lib/silcclient/client_prvmsg.c.
3448 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Do not add regex.h for WIN32. The affected file
3451 includes/silcincludes.h.
3453 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3454 not work yet 100%. It generates the DLL's automatically
3455 when compiling with --with-win32 under cygwin.
3457 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * lib/contrib/regex.c is not compiled on WIN32.
3461 * Added silc_net_get_socket_opt function to the
3462 lib/silcutil/silcnet.h.
3464 * Added includes/silcwin32.h for WIN32 specific includes
3467 * Do not use ptime structure or any of the posix process
3468 functions on WIN32 in lib/silccrypt/silrng.c.
3470 * Added silc_gettimeofday to provide generic function
3471 for struct timeval on all platforms. Added the function
3472 to lib/silcutil/silcutil.h.
3474 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3476 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3477 library as they clearly belong there. As a plus side we
3478 can make the actual socket connection routines platform
3481 Added also new generic function silc_socket_read and
3482 silc_socket_write (that used to be silc_packet_[read/write].
3483 The implementation of these are platform specific.
3485 * Added WIN32 specific routines of silc_socket_[read/write]
3486 to lib/silcutil/win32/silcwin32sockconn.c.
3488 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3490 * Added preliminary support for native WIN32 compilation under
3491 cygwin (using the -mno-cygwin option for GCC) to the
3492 ./configure.in.pre. The --with-win32 now prepares the
3493 compilation for native WIN32.
3495 * Rewrote the SILC Scheduler interface in the file
3496 lib/silcutil/silcschedule.h. The scheduler is now context
3497 based and does not have anymore any global static scheduler.
3498 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3499 and created lib/silcutil/win32 directory for WIN32 based
3502 * Added Unix specific network routines to the
3503 lib/silcutil/unix/silcunixnet.c and the old
3504 lib/silcutil/silcnet.c includes now only generic routines.
3506 Added WIN32 specific network routines to the
3507 lib/silcutil/win32/silcwin32net.c.
3509 * Added Unix specific utility functions from the
3510 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3512 * Added WIN32 SILC Scheduler to the file
3513 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3516 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Do not handle JOIN notify in the server if the target client
3519 is not registered (idata->registered == FALSE). The affected
3520 file is silcd/packet_receive.c.
3522 * Update the nickrec->founder in event_cumode in the Irssi SILC
3523 client. Affected file irssi/src/silc/core/silc-channels.c.
3525 * Fixed the CUMODE_CHANGE notify handling in the server when
3526 server and router are announcing their clients on channels.
3527 Now the mode changes are saved and notified correctly. The
3528 affected file is /silcd/packet_receive.c.
3530 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3531 They really did not replace the cache entry in the ID Cache.
3532 Now they do that. Affected file silcd/idlist.c.
3534 * Fixed the KICK notify handling in the Irssi SILC client to
3535 update the channel records so that the kicked client does not
3536 appear to be on the channel. The affected file is
3537 irssi/src/silc/core/silc-channels.c.
3539 * Always update the conn->current_channel when executing command
3540 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3542 * Fixed the KILL notify handling in Irssi SILC client to remove
3543 the killed client on all channels.
3545 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Fixed the silc_parse_command_line to remove extra spaces
3548 from the start and end of the arguments. Affected file is
3549 lib/silcutil/silcutil.c.
3551 * Cancel and free any active protocol in the function
3552 silc_server_close_connection. Affected file silcd/server.c.
3554 * Cancel and free any active protocol in the function
3555 silc_client_close_connction. Affected file is
3556 lib/silcclient/client.c.
3558 * Do not execute the KILL command for clients that are in
3559 history (ie. they are not in the network). Affected file is
3562 * Fixed KILL notify handling, client does not crash anymore.
3563 Affected file irssi/src/silc/core/silc-channels.c.
3565 * Reduced the default packet buffer size from 2048 to 1024 in
3566 lib/silccore/silcpacket.c.
3568 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3569 counter to the SKE context that is incresed when the SKE library
3570 performs async operation outside the library. If the outside
3571 process frees the SKE context and FREED status will be set
3572 and the library will detect after the sync operation that the
3573 libary is freed. The affected files are
3574 lib/silcske/silcske[_status].[ch].
3576 * Resolve the client entry information in the function
3577 silc_client_channel_message to assure that NULL pointer is not
3578 passed as client entry to the application. */
3580 * Fixed the task timeout calculation to assure that there is
3581 never negative timeouts. The affected file is
3582 lib/silcutil/silcschedule.c.
3584 * Fixed the channel user mode notification sending in server.
3585 It was sent point-to-point to the router (or to server by router)
3586 but it needs to be destined to a channel. The routines now
3587 supports sending the channel user mode notifys to the channels
3588 when announcing clients and channels. Affected files are
3589 silcd/server.c and silcd/packet_receive.c.
3591 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3592 It did not actually replace the old channel entry in the cache.
3593 Affected file lib/silcclient/client_notify.c.
3595 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Fixed a possible crash in silc_packet_send_prepare. It now
3598 assures always that there is enough space in the buffer and
3599 at the tail area of the buffer (for MAC).
3601 Fixed the inbound buffer reallocation in silc_packet_read.
3602 It was old code and did not handle the reallocation correctly.
3605 The affected file is lib/silccore/silcpacket.c.
3607 * Fixed buffer overflow in silc_parse_nickname in the file
3608 lib/silcutil/silcutil.c.
3610 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * make install generates new server keys only if there is not
3615 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3618 Added check that if the NOREPLY is set then we will not send
3619 the away message. This avoids infinite loop of away messages
3620 if both clients are away. The affected file is
3621 lib/silcclient/client_prvmsg.c.
3623 * Fixed client crash if /NICK was given without arguments.
3624 Affected file lib/silcclient/command.c.
3626 * Server does not send the invite list in INVITE command back
3627 to the client if the list was not altered. Added this notion
3628 to the protocol spec as well. Affected file silcd/command.c.
3630 Fixed possible crash in INVITE command by checking the
3631 value of silc_server_get_client_route command.
3633 * Fixed the INVITE notify type handling. The arguments are now
3634 taken in correct order and client does not crash. The affected
3635 file is irssi/src/silc/core/silc-channels.c.
3637 Removed the "Inviting xxx to channel" message from the
3638 client library away and let the application handle it.
3639 Affected file lib/silcclient/command.c. Added that message
3640 to Irssi SILC client's message formats.
3642 * Fixed CMODE command crash in client. It now checks the
3643 amount of arguments correctly and does not crash. The affected
3644 file is lib/silcclient/command.c.
3646 * Do not create new channel automatically in silc_channels_join
3647 but check whether the channel by that name already exists.
3648 Affected file irssi/silc/core/silc-channels.c.
3650 * Do not send the SERVER_SIGNOFF to router if the disconnected
3651 entity was the router. Affected file silcd/server.c.
3653 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3654 SILC client as it was missing from there.
3656 Added the handling of the KICK notify to the Irssi SILC client
3657 as it was missing. Added "you have been kicked" message to
3658 Irssi SILC client's message modules formats.
3660 Added the handing of the KILL notify to the Irssi SILC client
3661 as it was missing. Added the kill message module formats
3664 The affected file is irssi/src/silc/core/silc-channels.c.
3666 * The router did not save the channel mode the server announced.
3667 Affected file silcd/packet_receive.c.
3669 * Fixed a possible crash in INFO command in server. If the
3670 server did not provide the server info it crashed. Affected
3671 file silcd/command.c.
3673 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Fixed the GETKEY command in the server to check also the
3676 global list. Otherwise the GETKEY would not work correctly
3677 in normal SILC server. Affected file silcd/command.c.
3679 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Fixed GETKEY crash, it crashed if the command did not succseed.
3683 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3686 is now real and not just an macro interface to GMP.
3688 Removed the entire GMP from the source tree and imported new
3689 NSS MPI library instead. Reason for removing GMP is that it is
3690 extremely large and compiles extremely slow. The NSS MPI
3691 is only a few files and compiles in less than 10 seconds.
3692 The speed is also about the same as GMP. The MPI is imported
3693 to lib/silcmath/mpi.
3695 If the system has GMP installed we will still use the GMP.
3696 If it is not then the NSS MPI will be compiled.
3698 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Merged a long nickname (127 characters long) crash bugfix from
3701 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3703 * Merged a freed memory reference bugfix from Irssi CVS tree.
3704 Affected file irssi/src/core/commands.c.
3706 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Added the server's public key sving and verification to the
3709 server when performing the SKE. This was missing and the
3710 remote server's (or router's) public key was accepted without
3711 checking whether we have it previously or trust it at all.
3712 Affected file silcd/protocol.c.
3714 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Check in the silc_server_timeout_remote if protocol is active
3717 and make sure that the protocol's final callback is called so
3718 that all memory if freed. Affected file silcd/server.c.
3720 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * silc_server_whois_send_reply crashed the server if the nickname
3723 was 127 characters long. Affected file silcd/command.c.
3725 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Added sanity check to the silc_server_new_client. If the hostname
3728 is provided inside username then check that the provided hostname
3729 really is the same as the resolved one. If the hostname was not
3730 resolved then check it from the public key. Affected file is
3731 silcd/packet_receive.c.
3733 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3734 if the server disconnected us and the connection is not valid
3735 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3737 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3738 the library to the lib/silcutil/silcutil.[ch].
3740 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Close log file after open. Affected file
3743 lib/silcutil/silclog.c.
3745 * Check whether sock == NULL in silc_client_send_packet and return
3746 if it is. Affected file lib/silcclient/silcclient.c.
3748 * Check rec->entry == NULL in the Irssi SILC Client before
3749 sending the channel message. Affecte file is
3750 irssi/src/silc/core/silc-servers.c.
3752 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Merged a splitted window bugfix from Irssi CVS tree. The
3755 affected file is irssi/src/fe-text/textbuffer-view.c.
3757 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3758 It did not print nickname.
3760 * Improved the distributions system a bit.
3762 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3765 irssi/src/fe-text/gui-window.c.
3767 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3768 to in-active server. The affected file is
3769 irssi/src/silc/core/client_ops.c.
3771 * Resolve the client in USERS command reply if the entry does
3772 not have username resolved. The affected file is
3773 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3774 command to WHOIS command to really resolve stuff. The USERS
3775 is not used any more in any critical section so WHOIS can
3776 be used even though it might be slower than IDENTIFY.
3778 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3781 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Changed the protocol API a bit more consistent in the
3784 lib/silccore/silcprotocol.[ch].
3786 * Changed the following headers to ROBODoc format:
3788 lib/silccore/silcpayload.h
3789 lib/silccore/silcprotocol.h
3790 lib/silccore/silcsockconn.h
3792 All core library headers are now formatted.
3794 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Fixed a bug in Irssi SILC client; do not show that you are
3797 server/router operator if you really are not. Affected file is
3798 irssi/src/silc/core/client_ops.c.
3800 * Renamed silc_command_free_payload to silc_command_payload_free.
3801 Affected file lib/silccore/silccommand.h
3803 * Added silcmath.h to include the prototoypes of various routines
3804 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3807 * Changed the following headers to ROBODoc format:
3809 lib/silccore/silcchannel.h
3810 lib/silccore/silccommand.h
3811 lib/silccore/silcid.h
3812 lib/silccore/silcidcache.h
3813 lib/silccore/silcmode.h
3814 lib/silccore/silcnotify.h
3815 lib/silccore/silcpacket.h
3816 lib/silcmath/silcmath.h
3818 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Added checking to the server code not to start the server if
3821 ciphers and stuff are not configured properly. Affected files
3822 silcd/serverconfig.[h] and silcd/server.c.
3824 * Changed the layout of the header files of the public interfaces
3825 in the SILC libraries. The new layout supports ROBODoc
3826 documentation tool (and some others) so that it is easy to create
3827 a library reference manual. All the other headers and source
3828 code must still follow the CodingStyle document. Also source
3829 code must not include these ROBODoc stuffs, only the headers.
3830 Furthermore, all public interface headers must now be named
3831 by using `silc' prefix, example: silcapi.h, silccipher.h.
3832 Some files were renamed due to this. All the other headers
3833 must not be used as public interfaces. I will update the
3834 CodingStyle document later. Changed following headers, so far:
3836 lib/silcclient/silcapi.h
3837 lib/silccore/silcauth.h
3838 lib/silccore/silcprivate.h
3839 lib/silccrypt/silcdh.h
3841 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3845 * Removed silc_client_packet_send_flush from the client library
3846 as it is not needed. Affected file lib/silcclient/client.[ch].
3848 * Added printing of message of unresolved authentication method
3849 to the Irssi SILC client. Added it to the module formats.
3850 Removed the same message from the client library.
3852 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Added new distribution feature, DISTLABEL. Every distribution
3855 can define own preprocessor label that can be used in the
3856 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3857 file distributions, acconfig.h.pre and prepare.
3859 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Added Makefile.defines_int to include the actual definitions
3862 for Makefile.defines.in. Tested the new distribution system,
3863 created distributions and tested installation.
3865 * Added AWAY message printing to the Irssi SILC client. Added
3866 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3868 * Added SCONNECT command to call the SILC's CONNECT command.
3869 Cannot use CONNECT directly since Irssi uses that internally.
3870 Affected file irssi/src/silc/core/silc-servers.c.
3872 Added ACTION local command. It is same as ME command but takes
3873 the channel as mandatory argument.
3875 Rewrote some of the Irssi's help files to suite for SILC
3878 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Added Makefile.defines[.in] that should for now on be included
3881 in all Makefile.am file in the source tree. That file includes
3882 all common compilation definitions for SILC source tree.
3884 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Minor changes to the ./prepare script to change the package
3887 name according the distribution name to the configure.in.
3889 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3891 * Created new distribution system. Added file `distributions'
3892 that defines all the distributions that can be created out of
3893 the SILC source tree. The ./prepare script now reads that
3894 file to determine how to prepare the distributions. The
3895 first argument to the ./prepare is the name of the distribution
3896 and second is the version of the distribution. If given
3897 without arguments it creates the default (toolkit) distribution
3898 with the default version (defined in ./prepare).
3900 All Makefile.am files that are subject to the distributions
3901 are now named as Makefile.am.pre. These are ./Makefile.am
3902 and lib/Makefile.am. Others may be changed later.
3904 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Added invite list, ban list, some key management and connection
3907 error message printing to module formats in the Irssi SILC client.
3909 * Added new silc_client_set_away_message to set the away message
3910 that is back to the person who sent private message. The
3911 affected file lib/silcclient/silcapi.h and the
3912 lib/silcclient/client_prvmsg.c.
3914 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3916 * Fixed the private message sending in the Irssi SILC client,
3917 added local command KEY to the Irssi SILC client.
3919 Added key management and key agreement message formats to the
3920 irssi/src/fe-common/silc/module-formats.[ch].
3922 Added USERS (alias WHO) printing, server/router operator
3923 indication and LIST command printing to the module formats.
3925 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3927 * Fixed channel joining notify handling, cumode notify handling
3928 from Irssi SILC client.
3930 * Added SILC specific module-formats to the Irssi SILC client so
3931 that SILC specific message hilighting, colors etc is possible.
3932 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3934 Added channel mode, channel user mode, actions, notices,
3935 whois and whowas printing to the the module-formats.c.
3937 * Fixed a bug in channel deletion in the server. The channel
3938 is not left to the cache even if the channel founder auth mode
3939 is set when there are no users anymore on the channel. Affected
3940 file silcd/server.c.
3942 * The silc_net_localhost now resolves the entire hostname including
3943 the domain name. Affected file lib/silcutil/silcnet.c.
3945 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Changed the ask_passphrase client operation to be ascynchronous.
3948 It has now a completion callback and a context that the
3949 application must call after it has got the passphrase from
3950 the user. Affected files lib/silcclient/silcapi.h,
3951 lib/silcclient/protocol.c, lib/silcclient/command.c and
3954 Added SilcAskPassphrase callback that the application calls
3955 to deliver the passphrase to the library.
3957 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3958 The public key verification and especially a certificate
3959 verification is asynchronous procedure.
3961 Added new SILC_SKE_STATUS_PENDING status to indicate the
3962 request is pending and a callback will be called to finalize
3965 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3966 indicate that remote end did not send its public key (or
3967 certificate), even though we require it. Added check for this
3968 condition in the SKE. This was a security bug, now fixed.
3970 Defined new SilcSKEVerifyCbCompletion callback that is called
3971 when the verification process is completed.
3973 The affected files lib/silcske/silcske_status.h and
3974 lib/silcske/silcske.[ch].
3976 * Changed the verify_public_key client operation to be async
3977 as well. Defined SilcVerifyPublicKey callback that is used to
3978 indicate the success of the public key verification process.
3980 Changed the server and client to use the new async client
3983 * Changed the Irssi SILC client's internal scheduler to be called
3984 twice as many times as it used to be. As a result the client
3985 should be a bit faster now. Affected file is
3986 irssi/src/silc/core/silc-core.c.
3988 * Added support to Irssi SILC client of asynchronous public key
3989 verification and passphrase inquiry. Affected file is
3990 irssi/src/silc/core/silc-core.c.
3992 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Do not say "You have left channel %s" in client library.
3995 Moved it to the application. Affected files are
3996 lib/silcclient/command.c and silc/client_ops.c.
3998 * Fixed silc_client_get_clients. Command context was not
3999 duplicated and was freed memory in the callback. Affected
4000 file lib/silcclient/idlist.c.
4002 * Do not say "you are now talking..." on JOIN command in the
4003 client library. The appliation must handle it.
4005 * Do not say ".. changed topic to" in command reply in the
4006 client libary. The application must handle it.
4008 * Fixed TOPIC command sending in the client library.
4010 * Fixed a memory leak in silc_client_command_free in the file
4011 lib/silcclient/command.c.
4013 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Imported a modified version of Irssi client to the source tree.
4016 The Irssi will be used to create a new client called
4017 Irssi SILC. Imported to irssi/.
4019 Added silc_core_init_finish function to the Irssi. Affected
4020 file irssi/configure.in.
4022 A lot changes in the Makefile.ams around the irssi tree.
4024 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Do not rehash if the new size is same as the old size of the
4027 hash table, in the silc_hash_table_rehash*. The affected file
4028 lib/silcutil/silchashtable.c.
4030 * Replaced hash_table_del_by_context calls from the server
4031 (when channel->user_list and client->channels) to the
4032 hash_table_del as it is sufficient and faster.
4034 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Added silc_hash_table_list, silc_hash_table_get and the
4037 SilcHashTableList structure to provide an alternative way to
4038 traverse the hash table. The affected files are
4039 lib/silcutil/silchashtable.[ch].
4041 * Changed the server's idlist routines to use the hash table
4042 routines to optimize the code.
4044 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Replaced the client entry's `channel' list and channel entry's
4047 `user_list' list to hash tables for optimized lookup. Changed
4048 the code to use the hash table interface around the code.
4049 Affected file lib/silcd/idlist.[ch].
4051 * Added `auto_rehash' boolean argument to the function
4052 silc_hash_table_alloc to indicate whether the hash table should
4053 auto-rehash when it thinks is appropriate time. It will
4054 increase the hash table size if the there is twice as much
4055 entries in the table than the size of the table, and will
4056 decrease the size if there are twice as less entries than
4057 the size of the table.
4059 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4063 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * silc_idcache_purge_by_context deletes the entry now by context
4066 as it is supposed to do. Affected file lib/silccore/idcache.c.
4068 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4069 client is not anymore valid (WHOWAS givens the info) and not
4070 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4072 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Removed the `data' and `data_len' arguments from the ID Cache
4075 interfaces and added `name' argument. ID Cache does not handle
4076 anymore the binary data only a names associated with given ID.
4078 * When hashing a Client ID with silc_hash_id the entire ID is
4079 not hashed anymore, instead only the hash of the Client ID is
4080 hashed. This way we can access the Client ID from the cache
4081 with Client ID but with the hash of the ID (which is a hash of
4082 the nickname) as well without any difference in performance.
4084 Added also silc_idcache_find_by_id_one_ext to do one on one
4085 searching when we have the actual ID. Added also function
4086 silc_hash_client_id_compare. The affected files are
4087 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4089 * When hashing the name associated with a ID it is always done
4090 in lowercase. This way we can access the cache without worrying
4091 about case-sensitivity, even though, for example nicknames are
4094 * Fixed a bug in server with channel message sending. It put
4095 wrong ID type as destination ID. The affected file
4096 silcd/packet_send.c.
4098 * silc_idcache_del_by_context now deletes from all hash tables
4099 by context. Affected file lib/silccore/idcache.c.
4101 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Changed the client library to use the new ID Cache interface.
4104 Changes around the source tree.
4106 * Added silc_hash_table_rehash_ext to rehash with specific
4107 hash function. Affected file lib/silcutil/silchashtable.[ch].
4109 * Added silc_hash_string_compare to compare two strings in the
4110 hash table. Affected file lib/silcutil/silcutil.[ch].
4112 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4114 * Added new function silc_idcache_del_by_context into the
4115 lib/silccore/idcache.[ch].
4117 * Changed the server's ID list routines to use the new ID Cache
4118 interface. Changes around the source tree.
4120 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Added silc_hash_table_del[_by_context]_ext functions in to the
4123 lib/silcutil/silchashtable.[ch].
4125 Removed silc_hash_table_find_all* routines and added new
4126 silc_hash_table_find_foreach to replace them.
4128 Added silc_hash_table_replace_ext function as extended
4129 replacing function. Separated the simple hash table interface
4130 from the extended hash table interface in the file
4131 lib/silcutil/silchashtable.h.
4133 * Fixed minor bugs and changed it to use some of the new
4134 hash table functions in lib/silccore/idcache.c
4136 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added new function silc_hash_table_find_all to return all keys
4139 in the hash table by the specified key. As the hash table is
4140 collision resistant it also makes it possible to have several
4141 duplicate keys in the hash table. This function may be used to
4142 find all of the keys from the hash.
4144 Added user_context arguments to the SilcHashFunction,
4145 SilcHashCompare and SilcHashDestructor to deliver user specified
4148 Added new fuctions silc_hash_table_find[_all]_ext to do
4149 extended lookup with specified hash and compare functions and
4150 specified user contexts.
4152 Added new function silc_hash_table_add_ext to add the key
4153 with specified hash function and user context.
4155 Added new function silc_hash_table_foreach to traverse all
4156 entrys in the hash table. Added SilcHashForeach callback
4159 Added new function silc_hash_table_del_by_context to delete
4160 the entry only if the context associated with the key matches.
4162 Affected files are lib/silcutil/silchashtable.[ch].
4164 * Removed silc_hash_[server/client/channel]_id and added just
4165 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4166 silc_hash_id_compare to compare two ID's using as the hash table
4167 comparison function. Added also silc_hash_data to hash
4168 binary data and silc_hash_data_compare to compare it.
4170 * Removed silc_idlist_find_client_by_hash as it is not needed
4171 anymore. Affected file silcd/idlist.[ch].
4173 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4174 to use internally the SilcHashTable. The new ID Cache is a lot
4175 faster than the old one. Some of the ID Cache interface was also
4176 rewritten and obsolete and stupid functions were removed.
4178 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added entry_count field to the SilcHashTable to keep the number
4181 of the entries in the table. Implemented the function
4182 silc_hash_table_rehash. Added new function
4183 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4185 Fixed a minor bug in silc_hash_table_free.
4187 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4188 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4189 into the lib/silcutil/silcutil.[ch].
4191 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Implemented a collision resistant hash table into the
4194 lib/silcutil/silchashtable[ch]. See the header and the source
4195 for the SilcHashTable API.
4197 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Merged dotconf version 1.0.2 into lib/dotconf.
4201 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Do not compile anything in lib/silcsim/* if the SIM support
4204 is not enabled. The tree should now compile without problems
4207 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Compiled the SILC under cygwin. Compiled and tested briefly
4210 without problems. More tests needed. The SIMs didn't compile
4213 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4215 * Fixed possible crash in silc_get_username in the
4216 lib/silcutil/silcutil.c.
4218 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Fixed a va_arg in silc/client_ops.c.
4222 * Oops, RC5 routines were named AES and caused some problems
4223 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4225 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Added new SilcIDIP structure into the lib/silccore/id.h and
4228 replaced the old `ip' fields from all SILC ID's to that type.
4229 This is a step towards IPv6 support.
4231 The silc_id_get_len takes now the ID as an extra argument.
4232 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4233 both IPv4 and IPv6 based ID's.
4235 The affected files are lib/silccore/id.[ch] and other files
4236 around the tree using these routines.
4238 * Removed the ID length arguments in server from various
4239 silc_server_send_notify_* routines -> they are not needed
4242 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Fixed memory leak in silc_encode_pem_file in the file
4245 lib/silcutil/silcutil.c.
4247 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Check minor version as well in the SKE. Affected files are
4250 silcd/protocol.c and lib/silcclient/protocol.c.
4252 * Added --identifier option to the server so that an identifier
4253 can be when creating the public key for the server. Affected
4254 file is silcd/silcd.c.
4256 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4257 lib/silccrypt/silcpkcs.c.
4259 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Register default ciphers and stuff when using -C option with
4262 the server. Affected file sildc/silcd.c.
4264 * Put back the servers public key filename format, it is better
4265 than the new one. For now, the client keys are saved with the
4266 new filename format. The affected file silc/client_ops.c.
4268 * Implemented the Cipher API for the rest of the ciphers that
4269 did not implement it or implemented it the wrong way.
4271 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Register default ciphers and stuff when using the -S option
4274 in the client. Affected file silc/silc.c. Same also when
4275 creating new key pair with -C option.
4277 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Fixed the silc_verify_public_key client operation function to
4280 save the public keys differently. The fingerprint is now
4281 used as filename and not the hostname. This way also the
4282 client keys are saved uniquely and not with hostnames. The
4283 affected file is silc/client_ops.c.
4285 * Trimmed the silc_hash_fingerprint function to remove extra
4286 whitespaces from the end of the fingerprint. The affected
4287 file is lib/silccrypt/silchash.c.
4291 * Added silc_cipher_register_default function to register all
4292 default ciphers. It can be used when configuration files
4293 does not exist and the application does not want any specific
4294 ciphers in any specific order.
4296 The SilcDList is now used as silc_cipher_list dynamically
4297 allocated cipher list. Removed the static list all together
4298 and now all ciphers must be allocated to the dynamic list.
4299 The silc_cipher_alloc routine was changed to check only the
4302 All silc_cipher_* routines that used to return int returns
4305 The affected files lib/silccrypt/silccrypt.[ch].
4307 * The same thing was done to silc_hash_* as for silc_cipher_*
4308 routines. Affected files lib/silccrypt/silchash.[ch].
4310 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4311 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4312 Added also silc_pkcs_[un]register[_default] functions.
4313 Removed the data_context from the PKCS API.
4315 * Added silc_hmac_register_default function to register default
4316 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4317 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4318 to unregister all hmacs at once.
4320 * Register the default ciphers, hash functions, PKCSs and HMACs
4321 if client's configuration file does not exist. The affected
4324 * The client did not load the hash functions from the SIM
4325 modules at all. Added support for this. Affected file is
4326 silc/clientconfig.c.
4328 * When decoding public key with silc_pkcs_public_key_decode, check
4329 the supported algorithm only if PKCS are registered. Affected
4330 file lib/silccrypt/silcpkcs.c. The same was done with the
4331 silc_pkcs_private_key_decode.
4333 * Fixed the SILC List routines to keep the list always in order.
4334 It used to change the list's order when traversing the list but
4335 not it preserves the order. Affected file lib/trq/silclist.h.
4337 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Added the client library to use the SilcSocketConnection's
4340 reference counter (by silc_socket_dup) to prevent the bug that
4341 the socket object may be freed underneath async operation.
4343 * The name resolv library checking fixes in the configure.in.pre.
4346 * Created new version of the protocol drafts for future
4347 development. The -03 drafts are the ones that will be changed
4348 in the trunk now and the -02 will remain as they are.
4350 * Send list of CUMODE notifys to the router when announcing
4351 the channel users to the router. Affected file silcd/server.c.
4352 If the router receiving channel founder CUMODE for a channel
4353 that already has channel founder it will send CUMODE notify
4354 to the sender to remove the channel founder rights from the
4355 announced client. Affected file silcd/packet_receive.c.
4357 * The CUMODE notify may now use Server ID as well as the entity
4358 who changes the mode. Updated protocool specs.
4360 * Updated INSTALL and README files.
4362 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * New web pages in the http://silc.pspt.fi. The pages was
4369 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Implemented the [DenyConnectin] config section in the server.
4372 Added silc_server_config_denied_conn to check whether incoming
4373 connection is denied. Affected file silcd/serverconfig.[ch].
4375 * Do not check the ports when checking the incoming configuration
4376 data if the port is 0, meaning any. Affected file is
4377 silcd/serverconfig.c.
4379 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Fixed buffer overflow in silc_string_compare in the file
4382 lib/silcutil/silcutil.c.
4384 * Fixed double free in silc_server_command_leave in the file
4387 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Fixed the version checking in the server. Affected file is
4392 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4394 * Fixed the configuration data fetching when accepting new
4395 connections in the server. Affected file silcd/server.c.
4397 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Added `sender_entry' argument to the function
4400 silc_server_packet_relay_to_channel so that we can check
4401 whether some destination actually belongs to the same route
4402 the sender belongs (ie, we must not resend the packet to the
4403 sender). Affected file silcd/packet_send.[ch].
4405 * Added `servername' field to the SilcClientEntry in the server
4406 to hold the name of the server where client is from. Affected
4407 file is silcd/idlist.h.
4409 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Moved the channel message encrypting in the router betwen
4412 router connections from silc_server_channel_message to the
4413 silc_server_packet_relay_to_channel since we want to check
4414 whether we have anybody channel before encrypting anything.
4415 Affected files silcd/packet_[receive/send].c.
4417 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Fixed the [AdminConnection] server config section to support
4420 multiple entries. Affected file silcd/serverconfig.c.
4422 * Added support into the server to check the validity of the
4423 incoming connection before executing any KE or authentication
4426 * The connection configuration is now saved to the KE and
4427 connection auth protocol contexts and not fetched anymore in
4428 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4430 * The local hosts listenning address and port is also resolved
4431 now when starting the server. We want to have the socket object
4432 to include the real address and port for the listener. Added
4433 new function silc_net_check_local_by_sock into the files
4434 lib/silcutil/silcnet.[ch].
4436 * Fixed a broadcast bug in server -> do not broadcast if we
4439 * Fixed a routing bug. Do not route broadcast packets ever.
4440 Broadcast packets must be processed always and not routed since
4441 they may be destined to some other host than yourself and thus
4442 would get routed without no good reason. Affected file is
4445 * Added function silc_server_config_is_primary_route to check
4446 whether primary router connection has been configured (a router
4447 configuration that we are initiating). If there is not, we
4448 will assume that there is only two routers in the SILC network
4449 and we will use the incoming router connection as our primary
4450 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4452 * Changed the order of the broadcasting. Broadcast _after_ the
4453 packet has been processed not before. Affected file is
4456 * Fixed a [ClientConnection] parsing bug. The port was never
4457 parsed correctly thus resulting to port 0. Affected file
4458 silcd/serverconfig.c.
4460 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4461 argument and did not set the broadcast packet flag. Affected
4462 file silcd/packet_send.c. Fixed same bug in the function
4463 silc_server_send_notify as well.
4465 * If we receive NEW_ID packet for our own ID in the server, ignore
4468 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Removed the nickname from the Private Message Payload.
4473 Updated the code and the protocol specs.
4475 * Updated protocol specs for submitting to the IETF.
4477 * Tweaked the Random Number Generator a bit. Affected file
4478 lib/silccrypt/silcrng.c. Exported a new function
4479 silc_rng_[global]_add_noise which can be used to add more
4482 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Do not parse packets with different timeout when protocol
4485 is active -> may cause problem with rekey. Affected file
4488 * When server receives signoff notify it must not create
4489 new channel key if the client is on any channels since the
4490 sender of the signoff notify will create it.
4492 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Added printing of error messages during SKE protocol from the
4495 failure packet sent by server during SKE. Affected file
4498 * Removed the client's failure_callback handling with timeout
4499 and handle it immediately when received.
4501 * The SKE library returned wrong type in SUCCESS and FAILURE
4502 packets. They must be 32 bit MSB not 16 bit MSB.
4504 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Ok, rewrote the logic of the re-key and now it seems to work.
4507 I tested it on high traffic with frequent re-keys without
4508 problems. Added hmac_receive (and renamed hmac to hmac_send)
4509 in SilcClientConnection in lib/silcclient/client.h and
4510 in SilcIDListData in silcd/idlist.h. Also, removed the
4511 SilcPacketParserContext's cipher and hmac fields as they are
4512 not needed anymore and actually caused some problems when
4513 the ciphers and hmac's changed underneath the packet parser.
4515 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * If re-key protocol is active then process the incoming packets
4518 synchronously since we must assure that icoming packets encrypted
4519 with the old key is processed before the new keys is set to
4520 use. This is true other packets than for REKEY packets.
4521 Affected file silcd/server.c. The same was done to client library
4522 as well, affected file lib/silcclient/client.c.
4524 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Fixed bug in client and server to accept the force send if
4527 the packet is send from silc_[server/client]_packet_process
4528 function. Otherwise the packets are never delivered, oops.
4530 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Disable force sending of packets when REKEY protocol is active.
4533 We must assure that no packet is sent directly when rekey is
4534 performed. All packets must be sent through packet queue.
4535 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4536 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4537 function is silc_[server/client]_packet_send_real to check
4540 * Replaced the SIM paths from example config files to
4541 /usr/local/modules. Also, make install creates now
4542 /usr/local/silc/logs directory to hold all the SILC server
4545 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Made the configure.in.pre work on Solaris. Patch by salo.

4550 CBC mode macros into lib/silccrypt/ciphers_def.h.
4552 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Fixed the make install.
4556 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * When MAC computation fails the silc_packet_decrypt returned 0
4559 even though it was supposed to return -1. Fixed this. The
4560 affected file is lib/silccore/silcpacket.c.
4562 * Do not replace the config files in /etc/silc (in make install)
4563 if they already exist. Affected file ./Makefile.am.
4565 * Do not send re-key packets immediately but through packet queue.
4566 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4568 * Changed silc_net_check_host_by_sock to return FALSE if the
4569 IP/DNS could not be resolved. Though, it returns the IP address
4570 now even if it could not resolve it (but returns also FALSE).
4571 Affected file lib/silcutil/silcnet.[ch].
4573 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added silc_pkcs_decode_identifier to decode the public key's
4576 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4577 Added also silc_pkcs_free_identifier. Added also new context
4578 SilcPublicKeyIdentifier.
4580 * Added -S option to the silc client. It is used to dump the
4581 contents of the specified public key file.
4583 * Changed the PKCS api to return the public key length when
4584 setting the public key.
4586 * Fixed a fatal bug in the public and private key file loading.
4587 Affected file lib/silccrypt/silcpkcs.c.
4589 * Execute the packet parsing for client with zero (0) timeout
4590 if the protocol is active. Affected file silcd/server.c.
4592 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Made the key generation options to the silcd program. Added
4595 -C option, equivalent to client's option.
4597 * Added new [ServerKeys] config section to the server. It
4598 configures the server's public and private key.
4600 * Defined generic Public Key Payload into the protocol
4601 specification to send specific type of public keys and
4604 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4605 public key or certificate.
4607 * Implemented the GETKEY command to the server and to the
4608 client library and on user interface.
4610 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4642 lib/silcclient/client.h.
4646 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Do not ask whether user wants to use the negotiated private key
4649 for private messages, just use it. Affected file is
4650 silc/local_command.c.
4652 * Added `send_enc_key' and `enc_key_len' fields to the
4653 SilcIDListData structure since they are needed in the re-key

4677 * Changed _ALL_ unsigned long and unsigned int to uint32,
4678 unsgined short to uint16 in the source tree.
4680 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4681 not handle clients that has entry->data.registered == FALSE.
4682 They are not in the network anymore. Affected file is
4685 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4703 if the deleting was successful. Affected file silcd/idlist.[ch].
4705 * Added support for public key authentication in the connection
4706 authentication protocol in the client library. Affected file
4707 lib/silcclient/protocol.c.
4709 * Changed the server's silc_idlist_get_clients_by_* interface
4710 to support already allocated array so that new entries may be

4712 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4713 and command replies.
4715 * All command reply functions in the server now calls the
4716 pending command callback even if error occured. This way the
4717 error will be delivered to the client as well. Affected files
4718 silcd/command.c and silcd/command_reply.c.
4720 * Fixed INFO command to return local server's info if no server
4721 was provided. Affected file lib/silcclient/command.c.

4749 * Added SILC_UMODE_GONE mode to indicate when the client is not
4750 present in the SILC network. Added also support to the local
4751 command AWAY that will set this mode. Added support of showing
4752 "xxx is gone" in WHOIS command. The USERS command shows the
4753 gone status as well.
4755 * Fixed setting server and router operator privileges in the
4756 server's UMODE command. Affected file silcd/command.c.
4758 * Merged the SKE KE1 and KE2 payloads into one payload. The
4759 new KE payload is equivalent to the old KE2 payload.
4761 Cleaned up the SKE Start Payload parsing. It now uses the
4762 simple buffer unformatting to do the parsing. A lot faster
4765 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4766 to the SKE that is used to indicate whether both of the SKE
4767 parties should perform authentication. By default only the
4768 responder performs authentication. By setting this flag also
4769 the initiator must do authentication. By default it is unset
4770 since in normal SKE case, client to server connection, only
4771 the responder should do authentication. When doing SKE between
4772 two clients both should perform authentication. Updated the
4773 code and the protocol specs.
4775 * A little fix to IDENTIFY command in the server. Search the
4776 client first by hash not nickname. Affected file is
4779 * Fixed the silc_client_close_connection to support closing
4780 the client to client connections wihtout deleting too much
4781 data. Affected file lib/silcclient/client.c.
4783 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4784 are received if protocol used to be active but is not anymore
4785 the application would crash due to NULL pointer dereference.
4786 Affected files silcd/server.c and lib/silcclient/client.c.
4788 * Added `hash' field to the SilcClientConnection to include
4789 the hash function negotiated in the SKE protocol.
4791 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4792 to set the channel founder authentication data. A client can
4793 claim the founder rights later by providing the authentication
4794 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4795 This way the channel founder can regain the channel founder
4796 privileges even it is left the channel. This works only on
4797 local server and the client must be connected to the same
4798 server to be able to regain the founder rights. Updated the
4799 protocol specs accordingly.
4801 Added support to the CMODE command in the client to set the
4802 founder auth data. Read the README to see how to set it.
4804 Added support to the CUMODE command to claim the founder
4805 rights. Read the README to see how to do it.
4807 Added support for the founder authentication to the Channel
4808 Entry in the server. Affected file silcd/idlist.h.
4810 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4811 server's CMODE command. Affected file silcd/command.c.
4813 * Added the following new functions into lib/silccore/silcauth.[ch]:
4814 silc_auth_get_method and silc_auth_get_data.
4816 * The server now saves the remote hosts public key to the
4817 SilcIDListData pointer. Affected file silcd/protocol.c.
4819 * The normal server now does not remove the channel entry from
4820 the cache if the founder authentication data is set. It used
4821 to remove it if the founder was the last one on the channel on
4822 the server and left the channel. The auth data is saved and
4823 if the channel is re-joined later the old entry is used with
4824 the old auth data. Affected files silcd/command_reply.c and
4827 * Removed the `pkcs' field from the SilcIDListData structure
4828 in the server; it is not used. Affected file silcd/idlist.h.
4830 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Fixed packet processing on slow links. Partial packets were
4833 never re-processed because the incoming data buffer was cleared
4834 by the application. Application must not directly clear the
4835 sock->inbuf, the packet processing routines handle it. Fixed
4836 this in client library and in server.
4838 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Fixed the WHOIS and IDENTIFY send reply function to really
4841 check whether to send list or just one entry. Affected file
4844 * Cleaned up the LEAVE command's channel key distribution. The
4845 affected file silcd/command.c.
4847 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4848 can enforce the channel mode as well. In that case the ID
4849 includes the ID of the server. The code now enforces the
4850 mode change if the router have different mode than the server.
4852 * The notify client operation with CMODE_CHANGE notify can now
4853 return NULL client_entry pointer if the CMODE was not changed
4854 by client. Application must check for this.
4856 * Added <Server ID> argument to INFO command to support server
4857 info fetching by Server ID.
4859 * Added silc_server_announce_get_channel_users to get assembled
4860 packets of channel users of the specified channel. Affected
4861 file silcd/server.[ch].
4863 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4864 was freed underneath the ID Cache.
4866 * Re-announce clients when the server received CHANNEL_CHANGE
4867 notify from the router. Affected file silcd/packet_send.c.
4869 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4872 crashed since it did not handle the fact that there is no cipher
4873 called "3" and didn't check the error condition. Now fixed.
4875 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4876 flag. It can be used to send message requests.
4878 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Implemented the RESTART command in the client.
4882 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4883 notice type messages. Added notice printing to the user
4886 * The channel keys are not re-generated if the channel's mode
4887 is PRIVKEY, ie private key on the channel exists. Affected
4888 files silcd/server.c and silcd/command.c.
4890 * Fixed a little bug in channel message delivery when channel
4891 private keys are set in the server. Affected file is
4892 silcd/packet_send.c.
4894 * Changed the setting on channel->on_channel = TRUE from the
4895 silc_client_save_channel_key to the JOIN command reply. The
4896 key payload is not received if the private channel key is set.
4897 Affected file lib/silcclient/command_reply.c and the
4898 lib/silcclient/client_channel.c.
4900 * When the CMODE_CHANGE notify is sent and the channel private
4901 key mode is removed the channel key must be re-generated in
4902 other cells as well. Added this support for the router in the
4903 silcd/packet_receive.c.
4905 * Added new local command NOTICE to send notice message on
4906 channel. Affected file silc/local_command.[ch].
4908 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Added new local command ME to the client. It is used to send
4911 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4912 some action. Affected file silc/local_command.[ch].
4914 * Changed channel_message and private_message client operations
4915 to deliver the message flags to the application. Added also
4916 the `flags' arguments to the silc_client_send_channel_message
4917 and silc_client_send_private_message functions. Affected file
4920 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Redefined the Private Message Payload to support private message
4923 keys and to support the new private message flags. Updated
4924 the protocol specs. Flags makes it possible to have for example
4925 CTCP style messages.
4927 * Added new type SilcPrivateMessagePayload and defined an API
4928 for it in the lib/silcclient/silcprivate.[ch].
4930 * Tested private message private keys successfully. Tested the
4931 private message key set, unset and list commands with the new
4934 * Redefined the Channel Message Payload to include the channel
4935 message flags (equal with private message flags) to support
4936 for example CTCP style messages.
4938 * Defined some of the message (for channel and private message)
4939 flags. Updated the protocol specs and added the flags to the
4940 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4942 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Added SilcKeyAgreementStatus type to the key agreement routines
4945 to indicate the current status and error if one occured.
4946 The status types are defined in the lib/silcclient/silcapi.h.
4948 * Added new local command KEY that is used to set and unset private
4949 keys for channels, set and unset private keys for private messages
4950 with remote clients and to send key agreement requests and
4951 negotiate the key agreement protocol with remote client. The
4952 key agreement is supported only to negotiate private message keys,
4953 it currently cannot be used to negotiate private keys for channels,
4954 as it is not convenient for that purpose.
4956 * Fixed a minor pending callback setting bug in the function
4957 silc_client_get_client_by_id_resolve, now the function works.
4958 Affected file lib/silcclient/idlist.c.
4960 * Added function silc_net_get_local_port to get local bound
4961 port by socket. Added to lib/silcutil/silcnet.[ch].
4963 * Added `sockets' and `sockets_count' fields to the SilcClient
4964 object. They hold the sockets of the listenning sockets in
4965 the client. Listenning sockets may be for example the key
4966 agreement server. Affected file lib/silcclient/client.[ch].
4967 Added functions the silc_client_add_socket and the
4968 silc_client_del_socket. They are exported to the application
4971 * Added ~./silc/clientkeys to support other client's public keys.
4973 * Renamed verify_server_key client operation to verify_public_key
4974 and added one argument to indicate the type of the connection
4975 (server, client etc.).
4977 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Added silc_server_connection_auth_request to handle the
4980 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4981 silcd/packet_receive.[ch].
4983 * Added silc_server_send_connection_auth_request into the
4984 silcd/packet_send.c to send the connection auth request packet.
4986 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4989 * Fixed the public key authentication in responder side in the
4990 server. The `auth_data' pointer includes the SilcPublicKey
4991 not the path to the public key. Affected file silcd/protocol.c.
4993 * Implemented the public key authentication in the initiator side
4994 in the server. Affected file silcd/protocol.c.
4996 * Removed the [RedirectClient] config section from the server
4997 configuration. Is not needed and I don't want to implement it.
4999 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Cleaned up the CMODE command in the server. It now works
5002 correctly and supports all the modes defined in the protocol.
5003 Affected file is silcd/command.c.
5005 * Added `hmac_name' field to the SilcChannelEntry in the server
5006 to hold the default HMAC of the channel. It can be set when
5007 creating the channel (with JOIN command). Affected files
5010 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5011 type to indicate the change of the current cipher and hmac
5012 on the channel. Client can safely ignore the <cipher> argument
5013 (if it chooses to do so) since the CHANNEL_KEY packet will
5014 force the channel key change anyway. The <hmac> argument is
5015 important since the client is responsible of setting the new
5016 HMAC and the hmac key into use.
5018 * Fixed the CMODE command in the client library as well.
5020 * Tested CMODE command in router environment successfully.
5022 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Show the version of the remote client (or server) when connecting
5025 to the server. It is logged to the log file. Affected file
5026 is silcd/protocol.c.
5028 * Fixed the KILLED notify handling in the client library. The
5029 client must be removed from all channels when receiving the
5032 Also, do not remove the client entry when giving the KILL
5033 command but when the KILLED notify is received.
5035 * Removed silc_idlist_find_client_by_nickname from the server.
5036 Not needed anymore. Affected files silcd/idlist.[ch].
5038 * Implemented the CHANNEL_CHANGE notify type handling to the
5039 server. Affected file silcd/server.c.
5043 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5045 * Added silc_server_send_notify_invite to send the INVITE
5046 notify between routers.
5048 * Implemented the INVITE command correctly to the server.
5050 * Implemented the INVITE notify type handling in the server.
5052 * Implemented the INVITE command to the client library and on the
5055 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Added function silc_server_get_client_resolve to find the
5058 client entry by ID from all ID lists and then resolve it
5059 (using WHOIS) if it cannot be found. Affected file is
5062 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Implemented the BAN command to the client library.
5066 * The JOIN command in the server now checks the invite list
5069 * Changed the silc_command_reply_payload_encode_va and the
5070 silc_command_payload_encode_va to support that if argument is
5071 NULL it ignores and checks the next argument. Affected file
5072 lib/silccore/silccommand.c.
5074 * Added silc_server_send_notify_ban to send the BAN notify
5075 type between routers.
5077 * Chaned the silc_notify_payload_encode to support that if
5078 argument is NULL it ignores and checks the next argument.
5079 Affected file lib/silccore/silcnotify.c.
5081 * Tested ban lists in router environment successfully.
5083 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Implemented BAN command to the server, in silcd/command.[ch].
5087 * Removed the BAN and INVITE_LIST modes from the CMODE command
5090 * Added function silc_string_match to regex match two strings.
5091 Affected files lib/silcutil/silcutil.[ch].
5093 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Redefined parts of the SilcChannelEntry in the server to support
5096 the new ban and invite lists.
5098 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Redefined the INVITE command. The same command can be used to
5101 invite individuals to the channel but also to manage the invite
5102 list of the channel (to add to and remove from the invite list).
5103 Updated the protocol specs.
5105 * Added new command SILC_COMMAND_BAN that can be used to manage
5106 the ban list of the channel. Updated the protocol specs.
5108 * Removed the channel modes: the SILC_CMODE_BAN and the
5109 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5110 in the CMODE command. The equivalent features are now available
5111 using INVITE and BAN commands. Updated the protocol specs.
5113 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5114 in the network about change in the current ban list. The notify
5115 type is not used by the client.
5117 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5118 support the invite lists.
5120 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Added new function silc_string_regexify that converts string
5123 including wildcard characters into regex string that can
5124 be used by the GNU regex library. Added into the file
5125 lib/silcutil/silcutil.[ch].
5127 Added silc_string_regex_combine to combine to regex strings
5128 into one so that they can be used as one regex string by
5129 the GNU regex library. Added into the file
5130 lib/silcutil/silcutil.[ch].
5132 Added silc_string_regex_match to match two strings. It returns
5133 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5135 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Imported GNU regex to the soruce tree into lib/contrib.
5138 Fixed some compiler warning from the regex.c.
5140 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Fixed MOTD command in the server to work in router environment.
5144 * Fixed the MOTD command in the client library to support
5145 the server argument in the command.
5147 * Added `nickname_len' argument to the silc_idlist_add_client
5148 in the server, as the `nickname' argument may be binary data
5151 * Added silc_idlist_get_channels to return all channels from
5154 * Implemented LIST command to the server. Affected file is
5157 * Implemented the LIST command to the client library and on the
5160 * Added [<user count>] argument to the LIST command reply.
5161 With private channels the user count is not shown.
5163 * Updated TODO and README.
5165 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * The client entry's data.registered must be TRUE even with
5168 global client entry on global client list. The data.registered
5169 is used to check whether the client is anymore in the network,
5170 for example with WHOWAS command so it must be valid.
5172 * Fixed the WHOWAS command in the server. It now actually works
5173 in router environment. Added function into silcd/command_reply.c
5174 silc_server_command_reply_whowas_save.
5176 * Added silc_idlist_purge function to the silcd/idlist.c
5177 to periodically purge the ID Cache.
5179 * Fixed INFO command in the server. It works now in router
5180 environment. Added <server name> argument to the INFO command
5181 reply. Updated the protocol specs.
5183 * Fixed minor bug in silc_idcache_purge to not purge if the
5184 expire value is zero.
5186 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5187 they were buggy because of the WHOWAS information.
5189 * Fixed local command MSG to handle the async resolving of
5190 the remote client properly. It used to fail the first MSG.
5191 Affected file silc/local_command.c.
5193 * Added `data_len' field to SilcIDCache context.
5195 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Update TODO. Todo in commands in the server.
5199 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5202 used by routers as broadcast packet to inform other routers
5203 about the changed user mode.
5205 Implemented the notify handling in the server. Affected file is
5206 silcd/packet_receive.c. Added the function
5207 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5209 * Added new generic Channel Payload and deprecated the New Channel
5210 Payload. The New Channel Payload is now the generic Channel
5213 * Added new argument `mode' to the silc_server_send_new_channel
5214 as it is required in the Channel Payload now.
5216 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5217 and created a new and real SilChannelPayload to represent the
5218 new generic Channel Payload. Implemented the encode/decode
5219 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5221 * Added silc_server_get_client_channel_list to return the list
5222 of channels the client has joined for WHOIS command reply.
5223 Affected file silcd/server.[ch].
5225 * Implemented the channel list sending in the WHOIS command reply
5226 in server and in the client.
5228 Implemented the channel list displaying on the user interface
5229 as well. Affected file silc/client_ops.c.
5231 * Added silc_channel_payload_parse_list to parse list of Channel
5232 Payloads. It returns SilcDList list of SilcChannelPayloads.
5233 Client for example can use this function to parse the list of
5234 channels it receives in the WHOIS command reply. The caller
5235 must free the list by calling silc_channel_payload_list_free.
5236 Affected files lib/silccore/silcchannel.[ch].
5238 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Added one new argument <user mode> to the WHOIS command reply
5241 to return the mode of the user in SILC. Updated the protocol
5244 Implemented it to the server and client.
5246 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Fixed the mode printing on the user interface on joining.
5249 Affected file silc/client_ops.c.
5251 * Implemented the UMODE command and user modes in general to the
5252 client library and to the user interface.
5254 * Implemented the UMODE command to the server.
5256 * The server now sends UNKNOWN_COMMAND error status if client sends
5257 unknown command. Affected file silcd/command.c.
5259 * All server commands now handle the command identifier the right
5260 way when sending the command reply to the client. The client can
5261 use to identify the command replies with the identifier.
5263 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Added silc_server_get_client_route to resolve the route to
5266 the client indicated by the client ID. Affected file is
5269 * Added silc_server_relay_packet as general function to relay
5270 packet to arbitrary destination. This deprecates functions
5271 like _send_private_message_key, _relay_notify etc. Affected
5272 file is silcd/packet_send.[ch].
5274 Removed silc_server_send_key_agreement,
5275 silc_server_send_private_message_key and
5276 silc_server_packet_relay_notify functions from the file
5277 silcd/packet_send.[ch].
5281 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5282 server. Affected file silcd/packet_receive.[ch].
5284 * Implemented the KILL command to the client. Implemented the
5285 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5286 Affected files lib/silcclient/command[_reply].c and
5287 lib/silcclient/client_notify.c. Implemented the KILL notify
5288 printing in the user inteface.
5290 * Fixed a lot silc_parse_nick memory leaks from the client
5291 library in the file lib/silcclient/command.c.
5293 * Changed the silc_server_send_notify_on_channels's `sender'
5294 argument from SilcSocketConnection to SilcClientEntry to
5295 check the sender as entry and not as connection object and not
5296 to send to the client provided as argument. The affected file
5297 is silcd/packet_send.[ch].
5299 * The notify packets that are destined directly to the client used
5300 to not to be processed by the server. Now changed that and the
5301 server processes all notify packets. After relaying the packet
5302 to the client the notify packet is processed in the server.
5304 * The silc_server_free_client_data now checks whether there is
5305 pending outgoing traffic for the client and purges the data to
5306 the network before removing the client entry.
5308 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5311 an client is killed from the SILC Network. Updated the protocol
5314 Added new function silc_server_send_notify_killed to the
5315 silcd/packet_send.[ch].
5317 * Added function silc_server_packet_relay_notify to relay notify
5318 packets that are destined directly to a client. In this case
5319 the server does not process the notify packets but merely relays
5320 it to the client. Affected file silcd/packet_send.[ch].
5322 Added also silc_server_packet_process_relay_notify to check
5323 whereto relay the notify. Affected file is
5324 silcd/packet_receive.[ch].
5326 * Implemented the KILL command to the server.
5330 * Added the backup schema desgined last fall to the protocol
5331 specs for everyone to see. The specification is in the
5332 *-spec-xx.txt draft and the packet type definitions for the
5333 backup routers is in *-pp-xx.txt draft. Thusly, added also
5334 new packet type SILC_PACKET_CELL_ROUTERS.
5336 * A big security problem in the implementation discovered. The
5337 signoff of an client did not cause new channel key generation
5338 which it of course should've done. The channel keys must be
5339 always re-generated when client leaves (or signoffs) the channel.
5340 The silc_server_remove_from_channels funtion now handles
5341 the channel key re-generation.
5343 * Added `sender' argument to the silc_server_send_notify_on_channels
5344 to not to send the client provided as argument. Affected file
5345 silcd/packet_send.[ch].
5347 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Implemented OPER and SILCOPER commands into the server and
5352 * Added silc_auth_verify and silc_auth_verify_data to verify
5353 the authentication directly from the authentication payload.
5354 It supports verifying both passphrase and public key based
5355 authentication. Affected file lib/silccore/silcauth.[ch].
5357 * Added `hash' field to the SilcIDListData structure. It is the
5358 hash negotiated in the SKE protocol. Affected file is
5361 * Slight redesigning of the SilcAuthPayload handling routines.
5362 Do not send SilcPKCS but SilcPublicKey as argument.
5364 * Implemented the public key authentication support to the
5365 serverconfig. The public key is loaded from the provided path
5366 and saved as authentication data to void * pointer. Thus,
5367 changed the unsigned char *auth_data to void *auth_data;
5369 * Fixed SHUTDOWN command to send the reply before the server
5370 is shutdown. :) Affected file silcd/command.c.
5372 * Fixed fatal bug in CONNECT command. The hostname was invalid
5373 memory and server crashed. Affected file silcd/command.c.
5375 * Fixed fatal bug in CLOSE command. The server_entry became
5376 invalid but was referenced later in the command. Affected file
5379 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Fixed fatal bug in failure packet handling. Server ignored
5382 the failure and thus crashed when it came.
5386 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5389 that the command may be executed only once in (about) 2 seconds.
5390 The old SILC_CF_LAG flag is same but allows command bursts up
5391 to five before limiting.
5393 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5394 server code. Various commands now includes the CF_LAG_STRICT
5395 flag to disallow any kind of miss-use of the command.
5397 * Fixed the silc_buffer_unformat to not to allocate any data
5398 if the length of the data is zero. It used to allocate the
5399 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5401 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5403 * Changed the format of AdminConnection configuration section
5404 in the server. Added username of the admin to the format.
5405 Affected files silcd/serverconfig.[ch].
5407 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5408 to return admin configuration data by host, username and/or
5411 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Implemented WHOWAS command to the server. Added the functions:
5415 silc_server_command_whowas_parse,
5416 silc_server_command_whowas_send_reply,
5417 silc_server_command_whowas_from_client and
5418 silc_server_command_whowas_from_server
5420 * Added <Client ID> argument to the WHOWAS command reply. Updated
5421 the protocol specs accordingly.
5423 * Implemented WHOWAS command and command_reply to the client
5426 Implemented the WHOWAS printing on the user interface.
5428 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Added new argument to the WHOWAS command reply, the real name.
5431 It is an optional argument. Updated the protocol specs.
5433 * Added SilcIDCacheDestructor callback that is registered when
5434 the SilcIDCache is allocated. The callback is called when
5435 an cache entry in the ID Cache expires, or is purged from the
5436 cache. Added into lib/silccore/idcache.[ch].
5438 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5439 to destruct the client entries when the cache entry expires.
5440 Other ID Cache's in server and in the client library ignores
5443 * If the ID Cache entry's `expire' field is zero then the entry
5444 never expires. Added boolean `expire' argument to the
5445 silc_idcache_add function in the lib/silccore/idcache.[ch].
5446 If it is TRUE the default expiry value is used.
5448 * Added silc_server_free_client_data_timeout that is registered
5449 when client disconnects. By default for 5 minutes we preserve
5450 the client entry for history - for WHOWAS command.
5452 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added support to the server to enforce that commands are not
5455 executed more than once in 2 seconds. If server receives
5456 commands from client more frequently, timeout is registered
5457 to process the commands. Affected file silcd/command.c.
5458 Added new function silc_server_command_process_timeout.
5460 * Changed NICK_NOTIFY handling in client library to check that
5461 if the client's nickname was changed, so there is no need to
5462 resolve anything from the server.
5464 * Removed error printing from the WHOIS and IDENTIFY commands.
5465 If error occurs then it is ignored silently in the client library.
5466 The application, however, may map the received error to
5467 human readable error string. The application currently maps
5468 the NO_SUCH_NICKNAME error to string.
5470 * Made the command status message public to the application. Moved
5471 them from lib/silcclient/command_reply.c to
5472 lib/silcclient/command_reply.h. The application can map the
5473 received command status to the string with the
5474 silc_client_command_status_message function.
5476 * Added check to the server to check that client's ID is same
5477 as the Source ID in the packet the client sent. They must
5480 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added dist-bzip hook to the Makefile.am to make bzip2
5483 compressed distributions.
5485 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Server now enforces the maximum length for the nickname and
5488 the channel as protocol specification dictates. 128 bytes for
5489 nickname and 256 bytes for channel name.
5491 * Moved the WHOIS printing to the application. The client libary
5492 does not print out the WHOIS information anymore, the application
5493 must do it. Renamed silc_client_command_reply_whois_print to
5494 the silc_client_command_reply_whois_save.
5496 The client's idle time is also sent to the application now, and
5497 the idle is shown on screen.
5499 * Added silc_client_command_reply_identify_save to save the
5500 received IDENTIFY entries.
5502 * Do not check for channel private keys in message sending and
5503 reception if the channel does not have the PRIVKEY mode set.
5504 Affected file lib/silclient/client_channel.c.
5506 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5509 just surfaced after chaning the JOIN procedure.
5511 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added silc_client_get_clients_by_list to get client entries
5514 from Client ID list, that is returned for example by JOIN
5515 and USERS command replies. The application should use this
5516 function for example when JOIN command reply is received to
5517 resolve the clients already on the channel (library does not
5518 do that anymore as USERS command reply is not used in the JOIN
5519 procedure anymore). Affected files lib/silcclient/silcapi.h and
5520 lib/silcclient/idlist.c.
5522 * JOIN command reply and USERS command reply returns now SilcBuffer
5523 pointers instead of unsigned char pointers when returning
5524 the client list and mode list.
5526 * Added <Client ID> argument to the JOIN command reply, mainly
5527 for the server to identify for which client the command was
5528 originally sent. Updated protocol specs accordingly.
5530 * Added SilcDlist private_key pointer to the SilcChannelEntry
5531 in the client to support the channel private keys. Affected
5532 file is lib/silcclient/idlist.h.
5534 * Added SilcChannelPrivateKey argument to the function
5535 silc_client_send_channel_message so that application can choose
5536 to use specific private ke if it wants to. If it is not provided,
5537 the normal channel key is used, unless private keys are set.
5538 In this case the first (key that was added first) is used
5539 as the encryption key.
5541 * Implemented the support for channel private key handling.
5542 Implemented the following functions:
5544 silc_client_add_channel_private_key,
5545 silc_client_del_channel_private_keys,
5546 silc_client_del_channel_private_key,
5547 silc_client_list_channel_private_keys and
5548 silc_client_free_channel_private_keys
5550 Affected file lib/silcclient/client_channel.c.
5552 * Added the support for the private keys in the channel message
5553 sending and encryption and in the message reception and
5554 decryption. Affected funtions are
5555 silc_client_send_channel_message and silc_client_channel_message.
5557 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5559 * Added SKE's key verify callback to the client library's
5560 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5562 * Removed the statement that server (or router) must send USERS
5563 command reply when joining to the channel so that the client
5564 knows who are on the channel. Instead, the client list and
5565 client's mode list is now sent in the JOIN command reply to the
5566 client who joined channel. This is better solution.
5568 * Added function silc_server_get_users_on_channel and function
5569 silc_server_save_users_on_channel to the silcd/server.[ch].
5571 * Removed function silc_server_command_send_users from the
5574 * Do not show topic on the client library anymore. The topic is
5575 sent in the command reply notify to the application and the
5576 application must show the topic now.
5578 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Added client searching by nickname hash into the IDENTIFY and
5581 WHOIS commands in the server as they were clearly missing from
5582 them. Affected file is silcd/command.c.
5584 * Fixed a bug in private message receiving in the client library.
5585 The remote ID was freed and it wasn't supposed, now it is
5588 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Minor fix to the channel payload; allocate the data area, as it
5591 needs to be of specific length.
5593 * If the key agreement port is zero then the operating
5594 system will define the bound port. Affected files are
5595 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5597 * Added new function silc_channel_payload_decrypt into the file
5598 lib/silccore/silcchannel.[ch].
5600 * Moved the channel message etc, check from silc_packet_decrypt
5601 to applications. The library calls now a generic
5602 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5603 when the packet is either normal or special. This was done to
5604 allow more wide range of checking that was not allowed when
5605 the code was in library. Now applications can do virtually any
5606 checks to the packet and return to the library the decision how
5607 the packet should be processed. Affected files are
5608 lib/silccore/silcpacket.[ch].
5610 Added silc_server_packet_decrypt_check to the server and
5611 silc_client_packet_decrypt_check to the client library.
5613 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5614 to send with specified source and destination information.
5616 * Channel message delivery between routers was broken after the
5617 channel key distribution was fixed earlier. The channel key
5618 was used be to distributed to other routers as well which is not
5619 allowed by the protocol. Now this is fixed and channel keys
5620 really are cell specific and the channel message delivery between
5621 routers comply with the protocol specification.
5623 * Fixed various commands in server to check also the global list
5624 for the channel entry and not just the local list. The affected
5625 file silcd/command.c.
5627 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Added assert()s to buffer formatting and unformatting routines
5630 to assert (if --enable-debug) when error occurs. Affected
5631 file: lib/silcutil/silcbuffmt.c.
5633 * Changed to auto-reconnect to check whether the remote host is
5634 router and register the re-connect timeout if it is. It used
5635 to check that whether we are normal server, but router must do
5636 auto-reconnect with another router as well. Affected file
5639 * Removed the [<key len>] option from CMODE command as the cipher
5640 name decides the key length, nowadays. See the defined ciphers
5641 from the protocol specification.
5643 * Added [<hmac>] option to the CMODE command to define the HMAC
5644 for the channel. Added SILC_CMODE_HMAC channel mode.
5646 * Added [<hmac>] option for the JOIN command so that user can
5647 select which HMAC is used to compute the MACs of the channel
5650 * Added Hmac field to the Channel Message Payload. The integrity
5651 of plaintext channel messages are now protected by computing
5652 MAC of the message and attaching the MAC to the payload. The
5653 MAC is encrypted. Now, it is clear that this causes some
5654 overhead to the size of the packet but rationale for this is that
5655 now the receiver can verify whether the channel message decrypted
5656 correctly and also when private keys are set for the channel the
5657 receiver can decrypt the packet with several keys and check from
5658 the MAC which key decrypted the message correctly.
5660 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5661 lib/silccrypt/silccipher.[ch].
5663 * Added silc_hash_len to return the digest length into the
5664 lib/silcrypt/silchash.[ch].
5666 * Rewrote parts of Silc Channel Payload interface in the
5667 lib/silccore/silcchannel.[ch]. The encode function now also
5668 encrypts the packet and parse function decrypts it.
5670 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Fixed a minor formatting bug in the SKE's key material processing.
5673 It actually might have processed the keys wrong way resulting
5676 * Redefined the mandatory HMAC algorithms and added new algorithms.
5677 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5678 and hmac-md5 truncated to 96 bits. The mandatory is now
5679 hmac-sha1-96. Rest are optional (including the one that used
5680 to be mandatory). Rationale for this is that the truncated HMAC
5681 length is sufficient from security point of view and can actually
5682 make the attack against the HMAC harder. Also, the truncated
5683 HMAC causes less overhead to the packets. See the RFC2104 for
5686 * Added new [hmac] configuration section. The SKE used to use
5687 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5688 is of course wrong. The official names that must be proposed in
5689 the SKE are the ones defined in the protocol specification
5690 (hmac-sha1-96 for example). The user can configure any hmac
5691 using any hash function configured in the [hash] section. At
5692 least, the mandatory must be configured.
5694 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5696 * Added HMAC list to the SKE proposal list. It has now both
5697 hash algorithm list and HMAC list. This makes the protocol
5698 incompatible with previous versions. The SKE now seems to work
5699 the way it is supposed to work, for the first time actually.
5701 * Defined plain Hash algorithms to the protocol specification.
5704 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Implemented support for key agreement packets into the server.
5707 Added functions silc_server_key_agreement and
5708 silc_server_send_key_agreement. Other than these functions,
5709 server has nothing to do with this packet.
5711 * Added support for private message key packets into the server.
5712 Added functions silc_server_private_message_key and
5713 silc_server_send_private_message_key.
5717 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5718 called in the protocol's final callback instead in the END
5719 protocol state. This makes a little more sense and in the same
5720 time in client we can use the same protocol routines for normal
5721 key exchange and to key agreement packet handling as well.
5723 * Added to both client's and server's KE protocol context the
5724 SilcSKEKeyMaterial pointer to save the key material. We will
5725 bring the key material to the protocol's final callback by doing
5726 this. The final callback must free the key material.
5728 * Added SKE's packet_send callback into client's KE protocol
5729 context so that the caller can choose what packet sending function
5730 is used. This way we can use different packet sending when
5731 doing normal SKE when doing key agreement packet handling (in
5732 the key agreement packet handling we do not want to encrypt
5735 * Implemented the responder side of the key agreement routines
5736 in the client. The client can now bind to specified port and
5737 accept incoming key negotiation. The key material is passed
5738 to the application after the protocol is over.
5740 * Implemented the processing of incoming Key Agreement packet
5741 in the client. Added function silc_client_key_agreement to
5744 * Implemented the intiator side of the key agreement routines
5745 in the client. The client can now initiate key agreement with
5746 another remote client. The key material is passed to the
5747 application after the protocol is over.
5749 * Created client_keyagr.c to include all the key agreement
5752 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5753 SILC_TASK_CALLBACK except that it is not static.
5755 * Created client_notify.c and moved the Notify packet handling
5756 from the client.[ch] into that file.
5758 * Created client_prvmsg.c and moved all private message and
5759 private message key routines from the client.[ch] into that file.
5761 * Create client_channel.c and moved all channel message and
5762 channel private key routines from the client.[ch] into that file.
5764 * Changed silc_client_get_client_by_id_resolve to resolve with
5765 WHOIS command instead of IDENTIFY command, in the file
5766 lib/silclient/idlist.c.
5768 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Implemented the SKE's responder side to the Client library.
5772 * When FAILURE is received to the protocol do not trust it
5773 blindly. Register a timeout to wait whether the remote closes
5774 the connection as it should do it, only after that process the
5775 actual failure. This was changed to both client and server.
5777 * Added client_internal.h to include some of the structures
5778 there instead of client.h in lib/silcclient/.
5780 * Added function silc_task_unregister_by_callback to unregister
5781 timeouts by the callback function.
5783 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Some "Incomplete WHOIS info" errors has been appearing on the
5786 log files. Took away the entry->userinfo check from WHOIS
5787 reply sending. The entry->userinfo is now " " if client did not
5788 provide one. I thought this was fixed earlier but something
5789 is wrong still. Let's see if the error still appears.
5791 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Fixed a minor bug in the login when the channel key is
5794 re-generated in the server. It used to generate the key in
5795 wrong order and thus caused problems in the channel traffic.
5797 * Fixed a minor bug in channel key distsribution after
5798 KICK command. The key was not sent to the router even though
5801 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added silc_ske_process_key_material_data as generic routine
5804 to process any key material as the SILC protocol dictates. The
5805 function is used by the actual SKE library but can be used by
5806 applications as well. This relates to the private message keys
5807 and the channel private keys since they must be processed the
5808 same way the normal SILC session keys. The protocol dictates
5809 this. Affected files: lib/silcske/silcske.[ch].
5811 Added also silc_ske_free_key_material to free the
5812 SilcSKEKeyMaterial structure.
5814 * Defined silc_cipher_set_key function to set the key for
5815 cipher without using the object's method function. The affected
5816 files: lib/silccrypt/silccipher.[ch].
5818 * Implemented silc silc_client_add_private_message_key,
5819 silc_client_add_private_message_key_ske,
5820 silc_client_del_private_message_key,
5821 silc_client_list_private_message_keys and
5822 silc_client_free_private_message_keys functions in the
5825 Added functions silc_client_send_private_message_key to send
5826 the Private Message Key payload and silc_client_private_message_key
5827 to handle incoming Private Message Key payload.
5829 * Added Cipher field to the Private Message Key payload to set
5830 the cipher to be used. If ignored, the default cipher defined
5831 in the SILC protocol (aes-256-cbc) is used.
5833 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Removed lib/silcclient/ops.h file.
5837 Redefined parts of the SILC Client Library API. Created new
5838 file silcapi.h that deprecates the ops.h file and defines the
5839 published Client Library API. Defined also private message key
5840 API and channel private key API into the file.
5842 This is the file that the application must include from the
5843 SILC Client Library. Other files need not be included by
5844 the application anymore.
5846 * Added new key_agreement client operation callback and also
5847 defined the Key Agreement library API for the application.
5849 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5852 is used by clients to request key negotiation between another
5853 client in the SILC network. If the negotiation is started it
5854 is performed using the SKE protocol. The result of the
5855 negotiation, the secret key material, can be used for example
5856 as private message key.
5858 Implemented the Key Agreement payload into the files
5859 lib/silccore/silauth.[ch].
5861 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Redefined ciphers for the SILC protocol. Added some new ciphers
5864 and defined the key lengths for the algorithms. Changed the
5865 code accordingly. The default key length is now 256 bits.
5867 * Fixed SKE key distribution function silc_ske_process_key_material
5868 when the key length is more than 128 bits. The default key
5869 length in SILC is now 256 bits.
5871 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5872 to indicate unsupported algorithm.
5874 * Renamed rijndael.c to aes.c and all functions as well.
5876 * Fixed a long standing channel key setting bug in client library.
5877 Weird that it has never surfaced before.
5879 * Fixed bug in channel deletion. If the entire channel is removed
5880 then it must also delete the references of the channel entry
5881 from the client's channel list as the client's channel entry and
5882 the channel's client entry share same memory.
5884 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Implemented CONNECT and SHUTDOWN commands in the client.
5888 * Implemented CLOSE command to the client.
5890 * Added the function silc_idlist_find_server_by_name into the
5891 files silcd/idlist.[ch].
5893 Added the function silc_idlist_find_server_by_conn into the
5894 files silcd/idlist.[ch].
5896 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * DIE command was renamed to SHUTDOWN. Updated the both code
5901 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5902 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5904 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5907 * Added function silc_server_create_connection function to create
5908 connection to remote router. My server implementation actually
5909 does not allow router to connect to normal server (it expects
5910 that normal server always initiates the connection to the router)
5911 so the CONNECT command is only good for connecting to another
5914 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5917 or some other client was kicked from the channel.
5919 Implemented the handling of the notify type to both client
5922 Implemented silc_server_send_notify_kicked to send the KICKED
5923 notify. It is used to send it to the server's primary router.
5925 * Implemented the KICK command into server and client.
5927 * Added `query' argument to the silc_idlist_get_client function
5928 to indicate whether to query the client from server or not if
5931 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5932 to indicate that the client is not channel founder.
5936 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Removed the rng context from SilcPacketContext structure and
5939 changed that the packet routine uses the Global RNG API.
5941 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Added support for quit message that client can "leave" on the
5944 channel when it quits the SILC. It is ditributed inside the
5945 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5947 Added silc_server_free_client_data that will take the
5948 signoff message as argument.
5950 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5952 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Updated parts of the protocol specification to keep it up
5957 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5960 payloads in one packet.
5962 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5963 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5964 use now the new List flag.
5966 * Also deprecated the following packet types: REPLACE_ID,
5967 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5969 * Added list support for Notify packet in server.
5971 * Added silc_server_send_notify_channel_change to send the
5972 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5973 the silc_server_send_replace_id.
5975 * Added silc_server_send_notify_nick_change to send the
5976 NICK_CHANGE notify type. Deprecates the function
5977 silc_server_send_replace_id.
5979 * Added silc_server_send_notify_join to send the JOIN notify type.
5980 Deprecates the function silc_server_send_new_channel_user.
5982 * Added silc_server_send_notify_leave to send LEAVE notify type.
5983 Deprecates the function silc_server_send_remove_channel_user.
5985 * Added silc_server_send_notify_cmode and
5986 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5987 types. Deprecates the silc_server_send_set_mode function.
5989 * Added SERVER_SIGNOFF notify type to indicate that server has
5990 quit. This means that all clients on the channel from that
5991 server will drop. This can be also used when netsplit happens.
5993 Deprecated REMOVE_ID packet type since it is not needed anymore
5996 Added silc_server_send_notify_server_signoff to send the
5997 SERVER_SIGNOFF notify type. Deprecates the function
5998 silc_server_send_remove_id.
6000 Added also silc_server_send_notify_signoff to send the
6001 SIGNOFF notify type.
6003 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6004 SILC protocol from this day on. Changed the protocol
6005 specification as well.
6007 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6008 notify type. It is used between routers to notify about
6009 topic changes on a channel.
6011 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6014 * Partly updated the protocol specification to comply with the
6015 changes now made. It is still though a bit outdated.
6017 * The JOIN notify type now takes one extra argument <Channel ID>.
6018 The packet used to be destined to the channel but now the
6019 JOIN type may be sent as list thus it is impossible to
6020 destine it to any specific channel. By adding this argument
6021 it is again possible.
6023 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Added CREDITS file. The CHANGES and CREDITS file will appear
6026 in the distribution as well.
6028 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6031 types in the server's silcd/packet_receive.c.
6033 * Implemented CMODE and CUMODE to work in router environment.
6035 * Fixed minor encoding and decoding buglet from the
6036 lib/silccore/silcmode.c.
6038 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6041 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6043 * Changed all SilcConfigServer* and silc_config_server* to
6044 SilcServerConfig* and silc_server_config*, respectively.
6047 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * Associated the ID (client or server ID) to the Authentication
6050 Payload to avoid any possibility of forging. Updated the
6051 protocol specification and the code accordingly.
6053 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * The RSA key length is now save to the RsaKey context in the
6056 key generation process in lib/silccrypt/rsa.c. The key length
6057 is now used to figure out the maximum size of the block allowed
6058 to be encrypted/signed.
6060 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6061 is equivalent to the silc_mp_mp2bin but does not allocate any
6064 * Changed silc_mp_mp2bin API to take length argument. If it is
6065 non-zero then the buffer is allocated that large. If zero, then
6066 the size is approximated using silc_mp_sizeinbase, which however
6069 * Created Global RNG API which is global RNG that application can
6070 initialize. After initializing, any routine anywhere in the
6071 code (including library) can use RNG without allocating a new
6072 RNG object. This was done to allow this sort of use of the
6073 RNG in code that has no chance to allocate RNG object. All
6074 applications currently allocate this and many routines in the
6075 library use this. Affected file lib/silccrypt/silcrng.[ch].
6077 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6078 it to use the Global RNG API.
6080 * Defined Authentication Payload into protocol specification that
6081 is used during SILC session to authenticate entities. It is
6082 used for example by client to authenticate itself to the server
6083 to obtain server operator privileges.
6085 Implemented this payload into the lib/silccore/silcauth.[ch].
6086 Implemented also routines for public key based authentication
6087 as the new protocol specification dictates.
6089 Moved definitions of different authentication methods from
6090 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6092 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6093 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6094 silc_pkcs_verify_with_hash functions into the file
6095 lib/silccrypt/silcpkcs.[ch].
6097 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6099 * The client entry's userinfo pointer must be always valid.
6100 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6101 will fail since it requires the userinfo. Now, the userinfo
6102 is allocated as "" if actual userinfo does not exist. Actually,
6103 it must exist and it is totally Ok to drop client connections
6104 that does not announce the userinfo. However, we will make
6105 this workaround for now.
6107 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6108 to return the remote port by socket.
6110 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6113 SILC_SERVER_PENDING_EXEC and added an new macro
6114 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6115 data or when error occurs while processing the pending command.
6117 Added new argument `destructor' into silc_server_command_pending
6118 and to the SilcServerCommandPending object. This destructor is
6119 now called after calling the pending callback or if error occurs
6120 immediately. If error occurs the actual pending callback won't
6121 be called at all - only the destructor. The destructor may be
6122 NULL if destructor is not needed.
6124 All this applies for client library code as well. Similar
6125 changes were made there as well for the pending commands.
6127 In the client, the application must now allocate the
6128 SilcClientCommandContext with the silc_client_command_alloc
6131 * Added reference counter to the SilcServerCommandContext. Added
6132 function silc_server_command_alloc and silc_server_command_dup
6135 Same type of functions added to the client library for the same
6138 * Removed the cmd_ident from IDListData away since it is now
6139 global for all connections. It is the command identifier used
6140 in command sending and with pending commands. The affected file
6143 * Added reference counter to the SilcSocketConnection objecet to
6144 indicate the usage count of the object. The object won't be
6145 freed untill the reference counter hits zero. Currently only
6146 server uses this, and client ignores it. The client must be
6147 set to use this too later. The affected files are
6148 lib/silccore/silcsockconn.[ch]. Added also the function
6149 silc_socket_dup to increase the reference counter.
6151 This was mainly added because it is possible that the socket
6152 is removed underneath of pending command or other async
6153 operation. Now it won't be free'd and proper DISCONNECTING
6154 flags, etc. can be set to avoid sending data to connection that
6155 is not valid anymore.
6157 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6158 the connection. After that it sets SILC_SET_DISCONNECTED.
6159 It is, however, possible that the socket data is not still freed.
6160 The silc_server_packet_process now checks that data is not
6161 read or written to connection that is DISCONNECTED. The socket
6162 get's freed when the reference counter hits zero.
6164 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Changed the client operation API: channel_message operation's
6167 `sender' is now the client entry of the sender, not the nickname
6168 and the `channel' is the channel entry, not the channel name.
6170 In the private_message operation the `sender' is now also the
6171 client entry of the sender not the nickname.
6173 Affected file is lib/silcclient/ops.h and all applications
6174 using the client operations.
6176 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Moved the calling of ops->connect() from connect_to_server_final
6179 into receive_new_id functin since that is the point when the
6180 client is actually allowed to send traffic to network. The
6181 affected file is lib/silcclient/client.c.
6183 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6186 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6187 (if needs broadcasting) instead of broadcasting the packets one
6188 by one which would make a burst in the network traffic.
6190 * Added `broadcast' argument to the functions in silcd/server.[ch]
6191 silc_server_create_new_channel[_with_id] to indicate whether
6192 to send New Channel packet to primary router.
6194 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Added new function into the silcd/server.[ch] files:
6197 silc_server_create_new_channel_with_id to create new channel with
6198 already existing Channel ID.
6200 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6201 lib/silccore/silcpacket.h. This packet is used t send list of
6202 Set Mode payloads inside one packet. Server uses this to set
6203 the modes for the channels and clients on those channels, that it
6204 announced to the router when it connected to it. The protocol
6205 specification has been updated accordingly.
6207 * The silc_server_new_channel did not handle the packet coming
6208 from normal server as it normally does not send that. However,
6209 when it announces its channels it does send it. Implemented
6210 the support for that.
6212 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6213 into the file lib/silccore/id.h.
6215 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Fixed memory leaks in the functions silc_idlist_del_client,
6218 silc_idlist_del_channel and silc_idlist_del_server in the file
6219 silcd/idlist.c. All of those leaked like a sieve.
6221 * Fixed some small memory leaks in the client's function
6222 silc_client_notify_by_server.
6224 * Added functions into silcd/server.c: silc_server_announce_clients,
6225 silc_server_announce_channels and silc_server_announce_server.
6226 These functions are used by normal and router server to announce
6227 to its primary router about clients, channels and servers (when
6228 router) that we own. This is done after we've connected to the
6231 These functions effectively implements the following packet types:
6232 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6233 and SILC_PACKET_NEW_ID_LIST.
6235 * Added new functions into the silcd/packet_receive.[ch]:
6236 silc_server_new_id_list, silc_server_new_channel_list and
6237 silc_server_new_channel_user_list to handle the incoming
6238 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6240 * Added support of changing Channel ID in the function
6241 silc_server_replace_id. If the server that announces a channel
6242 to the router already exists in the router (with same name but
6243 with different Channel ID), router is responsible to send
6244 Replace ID packet to the server and force the server to change
6245 the Channel ID to the one router has.
6247 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6248 client that the Channel ID has been changed by the router. The
6249 normal server sends this to the client. Client must start using
6250 the new Channel ID as the channel's ID.
6252 Implemented handling of this new type into lib/silcclient/client.c
6253 into the function silc_client_notify_by_server.
6255 * Added new function silc_idlist_replace_channel_id into the files
6256 silcd/idlist.[ch] to replace the Channel ID.
6258 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Call silc_server_command_identify_check always when processing
6261 the IDENTIFY command in silcd/command.c
6263 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6266 send keepalive packets. The packet can be sent by clients,
6267 servers and routers.
6269 Added function silc_socket_set_heartbeat into the file
6270 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6271 If not set, the heartbeat is not performed. The actual
6272 heartbeat is implemented in the low level socket connection
6273 library. However, application is responsible of actually
6276 Added silc_server_send_heartbeat to send the actual heartbeat
6277 packet into silcd/packet_send.[ch]. Server now performs
6278 keepalive with all connections.
6280 * Added silc_task_get_first function into lib/silcutil/silctask.c
6281 to return the timeout task with shortest timeout. There was a bug
6282 in task unregistration that caused problems. TODO has been
6283 updated to include that task system must be rewritten.
6285 * The client library will now resolve the client information when
6286 receiving JOIN notify from server for client that we know but
6287 have incomplete information.
6289 * Rewrote parts of silc_server_remove_from_channels and
6290 silc_server_remove_from_one_channel as they did not remove the
6291 channel in some circumstances even though they should've.
6293 * Encryption problem encountered in server:
6295 The LEAVE command used to send the Channel Key packet to the
6296 router immediately after generating it. However, the code
6297 had earlier sent Remove Channel user packet but not immediately,
6298 ie. it was put to queue. The order of packets in the router
6299 was that Channel Key packet was first and Remove Channel User
6300 packet was second, even though they were encrypted in the
6301 reverse order. For this reason, MAC check failed. Now, this
6302 is fixed by not sending the Channel Key packet immediately but
6303 putting it to queue. However, this is more fundamental problem:
6304 packets that are in queue should actually not be encrypted
6305 because packets that are sent immediately gets encrypted
6306 actually with wrong IV (and thus MAC check fails). So, packets
6307 that are in queue should be encrypted when they are sent to
6308 the wire and not when they put to the queue.
6310 However, the problem is that the current system has not been
6311 designed to work that way. Instead, the packet is encrypted
6312 as soon as possible and left to the queue. The queue is then
6313 just purged into wire. There won't be any fixes for this
6314 any time soon. So, the current semantic for packet sending
6317 o If you send packet to remote host and do not force the send
6318 (the packet will be in queue) then all subsequent packets to the
6319 same remote host must also be put to the queue. Only after the
6320 queue has been purged is it safe again to force the packet
6323 o If you send all packets immediately then it safe to send
6324 any of subsequent packets through the queue, however, after
6325 the first packet is put to queue then any subsequent packets
6326 must also be put to the queue.
6328 Follow these rules and everything works fine.
6330 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Added new function silc_server_remove_clients_by_server to
6333 remove all client entries from ID list when the server connection
6334 is lost. In this case it is also important to invalidate all
6335 client entires as they hold the invalid server entry. This
6336 fixes fatal bug when server has lost connection and will reconnect
6339 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6341 * Made some sanity checks to silc_server_daemonise like to check
6342 whether the requested user and group actually exists.
6344 * Added sanity check to SKE's silc_ske_responder_finish to check
6345 that the public and private key actually is valid.
6347 * Invalidate the client's nickname when receiving Replace ID
6348 packet and the Client ID is being replaced. This means that the
6349 server will query the nickname if someone needs it (client)
6352 * Sort the ID Cache in client library when the ID Cache data
6353 has changed (needs sorting).
6355 * Do not allow for SILC client to create several connections to
6356 several servers. The client does not support windows right now
6357 and generating multiple connections causes weird behaviour.
6359 Irssi-silc client does support windows and can handle several
6360 connections without problems, see: www.irssi.org and SILC plugin.
6362 * Fixed some places where client was added to the IDList. The
6363 rule of thumb is following (in order to get everything right):
6364 If the client is directly connected local client then the
6365 `connection' argument must be set and `router' argument must be
6366 NULL to silc_idlist_add_client function. If the client is not
6367 directly connected client then the `router' argument must
6368 bet set and the `connection' argument must be NULL to the
6369 silc_idlist_add_client function.
6371 * The funtion silc_server_packet_send_local_channel actually did
6372 not check whether the client was locally connected or not. It
6373 does that now. Fixed a bug related to LEAVE command.
6375 * Fixed Remove Channel User payload parsing bug in server's
6376 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6378 * The server's silc_server_save_channel_key now checks also the
6379 global ID list for the channel as it might not be in the local
6380 list. Fixed a bug related to LEAVE command.
6382 * Is this the end of the [<unknown>] buglet that has been lurking
6383 around for a long time? A little for loop fix in server's
6384 silc_server_command_whois_parse that is used by both IDENTIFY
6385 and WHOIS command. At least, this was a clear bug and a cause
6386 of one type of [<unknown>] buglet.
6388 * WHOIS and IDENTIFY commands call the function
6389 silc_server_command_[whois/identify]_check function even if
6390 we are not router server.
6392 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Added --with-gmp configuration option. If set the GMP
6395 is always compiled in the SILC source tree. If not set then
6396 it is checked whether the system has the GMP3 installed. If
6397 it has then the GMP won't be compiled (the system's headers
6398 and library is used), if it doesn't have it then the GMP is
6399 compiled in the SILC source tree.
6401 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Changed RSA private exponent generation to what PKCS #1
6404 suggests. We try to find the smallest possible d by doing
6405 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6406 not security fix but optimization.
6408 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Added new config entry [Identity] to fork the server and run
6411 it as specific user and group. A patch from Bostik.
6413 * Imported Dotconf configuration library into lib/dotconf.
6414 This will be used to create the SILC configuration files later.
6415 It will appear in the distsribution after this commit.
6417 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * A big code auditing weekend happening. Auditing code for
6420 obvious mistakes, bugs and errors. Also, removing any code
6423 Removed files for being obsolete:
6425 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6426 inline in the file lib/silcutil/silcbuffer.h)
6428 o lib/silcutil/silcbufutil.c (the header has inline versions)
6430 Changed code to fix possible error conditions:
6432 o The buffer formatting routines now check that the destination
6433 buffer really has enough space to add the data. This applies for
6434 both buffer formatting and unformatting
6435 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6436 unformatting was changed to accomodate following rules:
6437 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6438 sent to the function while XXX_*STRING will not allocate or copy
6439 the data into the buffer. Instead it sets the pointer from the
6440 buffer into the pointer sent as argument (XXX_*STRING used to
6441 require that the pointer must be allocated already). This change
6442 makes this whole thing a bit more consistent and more optimized
6443 (note that the data returned in the unformatting with XXX_*STRING
6444 must not be freed now). The routines return now -1 on error.
6446 o Tried to find all code that use buffer_format and buffer_unformat
6447 and added return value checking to prevent formatting and
6448 especially unformatting errors and possible subsequent fatal
6451 o Changed ske->x and ske->KEY to mallocated pointers in
6452 lib/silcske/silcske.h. Fixed possible data and memory leak.
6454 o Added return value checking to all *_parse* functions. Fixed
6455 many memory leaks as well.
6457 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6458 so that buffer overflows would not happen. All code now also
6459 checks the return value as it can fail.
6461 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Added reconnection support to server if the normal server looses
6464 its connection to the router (for example if router is rebooted).
6465 The server performs normal reconnection strategy implemented
6466 to the server. Affected file silcd/server.c.
6468 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Added new packet type SILC_PACKET_SET_MODE that is used to
6471 distribute the information about changed modes (for clients,
6472 channels and clients channel modes) to all routers in the
6473 network. Updated the protocol specification accordingly.
6475 Added functions into silcd/packet_send.c and
6476 silcd/packet_receive.c: silc_server_send_set_mode,
6477 silc_server_set_mode.
6479 Added new files silcmode.[ch] into lib/silccore that implements
6480 the encoding and decoding of Set Mode Payload. Added new type
6481 SilcSetModePayload. Moved the definitions of different modes
6482 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6484 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * Oops, a little mistake in server's connection authentication
6487 protocol. The protocol is not ended with FAILURE but with
6488 SUCCESS if the authentication is Ok. :) Affected file is
6491 * Implemented NICK_CHANGE notify handling in server in the file
6492 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6493 the local clients on the channel. After the changing nickname
6494 in router environment snhould work and the [<unknown>] nickname
6495 should appear no more.
6497 The silc_server_replace_id function that receives the Replace ID
6498 payload now sends the NICK_CHANGE notify type also in the file
6499 silcd/packet_receive.c
6501 * Changed WHOIS and IDENTIFY command to support the maximum amount
6502 of arguments defined in protocol specs (3328 arguments). This
6503 fixed a bug that caused problems when there were more than three
6506 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Added extra parameter, command identifier, to the
6509 silc_client_send_command so that explicit command identifier
6512 Changed that ID list routines uses specific command identifier
6513 when sending WHOIS/IDENTIFY requests to the server so that they
6514 can be identified when the reply comes back.
6516 Affected files lib/silcclient/command.[ch],
6517 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6519 * Added `sender' argument to silc_server_packet_send_to_channel
6520 to indicaet the sender who originally sent the packet to us
6521 that we are now re-sending. Ignored if NULL. Affected file
6522 silcd/packet_send.[ch].
6524 * Added some server statistics support in silcd/server_internal.h
6525 SilcServerStatistics structure and around the server code. Also
6526 send some nice statistics information when client is connecting
6529 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Fixed channel ID decoding in server's JOIN command reply in
6532 silcd/command_reply.c
6534 * Fixed braodcasting of replace ID payload to not to send it if
6535 we are standalone server in silcd/packet_receive.c.
6537 * Fixed all channel message sending routines to not to send
6538 packets to clients that has router set, since they are routed
6539 separately in the same function earlier. Affects file
6540 silcd/packet_send.c and all channel packet sending functions.
6542 * In USERS reply, res_argv[i] are not allocated, the table
6543 is allocated. Thus changed that free the table, not its
6546 * In server's whois_check and identify_check if the client is
6547 locally connected do not send any WHOIS commands - they are not
6550 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Fixed some minor bugs in client when sending WHOIS command. The
6553 arguments was in wrong order.
6555 * Removed statis function add_to_channel from server in
6556 silcd/command.c that was previously used with the joining but
6559 * Tested USERS command in router environment successfully with two
6560 routers, two servers and two clients.
6562 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Reorganized the USERS command and command reply in client library
6565 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6566 When the command is given by user we register a pending command
6567 callback that will reprocess the command after the reply has been
6568 received from the server. When reprocessing the packet we then
6569 display the information. Thus, the USERS information is displayed
6570 now in the command callback instead of in the command reply
6571 callback. The processing of the command is same as previously
6572 when server has sent the command reply in the JOINing process.
6574 * Added to USERS command in silcd/command_reply.c to join the client,
6575 we didn't use to know about, to the channel after we've created
6576 a client entry for it. Also, for clienet we did know already still
6577 check whether it is on the channel or not and add it if not.
6579 * Removed silc_server_command_join_notify as the function and its
6582 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Changed the client's pending command handling to the same as the
6585 server's pending command handling. It is also now possible to
6586 execute command reply functions from other command reply
6587 function as the function callbacks for commands and command
6588 replies are one and same. The pending commands are not static
6589 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6590 in client connection context. Thus, pending commands are server
6591 connection specific as it is convenient.
6593 Changed the function silc_client_command_pending and
6594 silc_client_command_pending_del and added new function
6595 silc_client_command_pending_check. Removed the
6596 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6599 * Added cmd_ident, current command identifier, to the client
6600 connection context in lib/silcclient/client.h to keep track on
6601 command identifiers used in command sending. Client's command reply
6602 function handling now supports the mandatory command identifiers.
6604 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6605 funtions in client to fully support pending command callbacks.
6607 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6608 as one of the arguments to the application in the command reply
6611 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6612 before first releasing SILC but came back. Now it is removed again
6613 and should come back nomore. The FORWARDED flag was used only
6614 by the JOINing procedure by forwarding the command packet to router.
6615 Now, the JOINing procedure has been changed to more generic (due
6616 to various router environment issues) and FORWARDED is not needed
6617 anymore for anything. The protocol specification is yet to be
6620 Now, removed silc_server_packet_forward from server and the flag
6621 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6623 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6625 * Renamed NAMES command to USERS command. The NAMES was named that
6626 due to historical reasons. Now it is renamed. Also, rewrote
6627 parts of the USERS command. The nickname list is not sent anymore
6628 by the server. Only Client ID and mode lists are sent in the USERS
6629 command. Changed this also to the protocol specification.
6631 The client now resolves the names and stuff after it receives
6632 the USERS list from the server when joining to the channel.
6634 * WHOIS and IDENTIFY commands has been changed to support multiple
6635 Client ID's per command. One can now search for multiple users
6636 in the network by sending only one WHOIS or IDENTIFY command.
6637 Changed the code and the protocol specifications.
6639 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6640 uses silc_server_command_whois_parse to parse the request. */
6642 * If normal server, do not parse the WHOIS and IDENTIFY requests
6643 before sending it to the router. Saves some time.
6645 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Fixed JOIN command on client library. Wrong number of arguments
6648 used to crash the client.
6650 * Added silc_server_channel_has_global function to check whether
6651 channel has global users or not.
6653 * Added silc_server_channel_has_local function to check whether channel
6654 has locally connected clients on the channel.
6656 * The silc_server_remove_from_one_channel now checks whether the
6657 channel has global users or not after given client was removed from
6658 the channel. It also checks whether the channel has local clients
6659 on the channel anymore. If it does not have then the channel entry
6660 is removed as it is not needed anymore.
6662 * The silc_server_notify now checks on JOIN notify whether the joining
6663 client is one of locally connected or global. If it is global then
6664 the channel has now global users on the channel and that is marked
6665 to the channel entry. Also, it now saves the global client to
6666 global list who is joining and JOINs it to the channel. This is
6667 for normal server, that is.
6669 Changed silc_server_send_notify_on_channel,
6670 silc_server_packet_relay_to_channel and
6671 silc_server_packet_send_to_channel check if we are normal server
6672 and client has router set (ie. global client) do not send the
6673 message to that client, as it is already routed to our router.
6675 * Implemented LEAVE notify type handling in silc_server_notify
6678 * Tested LEAVE command in router environment successfully. Tested
6679 with two routers, two servers and two clients.
6683 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6685 * Implemented SIGNOFF notify type handling in silc_server_notify
6688 * silc_server_remove_id now removes the client entry from all channels
6689 it has joined and thusly sends SIGNOFF notify type.
6691 * Rewrote the NAMES list generation in server by removing two excess
6692 loops. The lists are created now inside one loop.
6694 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * silc_server_remove_channel_user checks now also global list
6697 for channel and client.
6699 * silc_server_new_channel_user checks now both local and global
6700 list for channel and client. Fixed a bug in client id decoding.
6701 Used to decode wrong buffer.
6703 * silc_server_channel_message checks now both local and global
6704 list for channel entry.
6706 * Tested channel joining (hence JOIN) in router environment
6707 successfully. Tested with two routers, two servers and two
6710 * Tested channel message sending in router environment successfully.
6712 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Added silc_server_save_channel_key into server.[ch] to save the
6715 received channel key in Channel Key payload processing. It is
6716 also used in JOIN command reply handling.
6718 Equivalent function silc_client_save_channel_key added into
6719 client.[ch] into client library.
6721 * Changed JOIN command reply to send information whether the channel
6722 was created or not (is existing already) and the channel key
6723 payload. Changed protocol specs accordingly.
6725 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6726 the request was sent by ID and not by nickname. Crashed on
6729 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6731 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6732 now correctly save the received data.
6734 * silc_server_free_sock_user_data now notifies routers in the
6735 network about entities leaving the network.
6737 At the same time implemented functions silc_server_remove_id
6738 and silc_server_send_remove_id to receive and send REMOVE_ID
6739 packets. The packet is used to notify routers in the network
6740 about leaving entities. The ID removed will become invalid in
6743 * Added function silc_idlist_del_server into server. Removes and
6744 free's server entry from ID list.
6746 * silc_server_private_message function now checks, if we are router,
6747 that the destination ID really is valid ID, naturally.
6749 * In router when NEW_ID packet is received (for new client) the
6750 hash of the Client ID is saved in the ID Cache but the
6751 client->nickname is set to NULL, instead of putting the hash
6754 IDENTIFY command now also checks that client->nickname must be
6755 valid. If it is not if will request the data from the server who
6756 owns the client. Added new function
6757 silc_server_command_identify_check.
6759 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6760 to set the command to already allocated Command Payload.
6762 * Tested private message sending in router environment with two
6763 routers, two servers and two clients. Fixed minor bugs and now
6766 * Fixed segfault from client's NAMES command. Used to crash if
6769 * Forwarded packets must not be routed even if it is not destined
6770 to the receiver. Changed server code comply with this.
6772 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Added `require_reverse_mapping' boolean value to ServerParams
6775 structure. If TRUE (not default) the server will require that
6776 the connecting host has fully qualified domain name.
6778 If the reverse mapping is not required and hostname could not be
6779 found the IP address is used as hostname.
6781 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6783 * Implemented version string checking to both client and server.
6784 The check is incomplete currently due to the abnormal version
6785 strings used in development version of SILC.
6787 * Changed all command functions in server to use the new
6790 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6792 * Changed char *data to unsigned char *data in ID Cache system to
6793 support binary data as ID Cache data. Changed code to support
6794 binary data in lib/silccore/idcache.c.
6796 * Renamed silc_server_packet_relay_command_reply to
6797 silc_server_command_reply as it is normal packet receiving
6798 function. Rewrote the function to accept command replys for
6799 servers and not only for clients.
6801 * Mark remote router always as registered server if we are connecting
6802 to it. Otherwise, commands sent by the router to us are ignored.
6804 * All ID List find routines now returns the ID Cache Entry pointer
6805 as well if requested.
6807 * WHOIS command works now in router environment, tested with two
6808 routers, two servers and two clients.
6810 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6811 in router environment (as it is almost equivalent to WHOIS) but
6812 hasn't been tested thoroughly. Added new functions:
6814 silc_server_command_identify_parse
6815 silc_server_command_identify_send_reply
6816 silc_server_command_identify_from_client
6817 silc_server_command_identify_from_server
6819 * Disabled route cache adding because adding two different ID's with
6820 same IP replaces the old cache entry thus giving wrong route.
6821 The entry->router->connection is always the fastest route anyway
6822 so route cache may not be needed. Of course, new routes maybe
6823 established after receiving the ID when the entry->router->connection
6824 might not be anymore the most optimal.
6826 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Add route cache for received ID for fast routing.
6830 * Added silc_server_packet_route to route received packet on router
6831 that is not destined to us.
6833 * Renamed silc_server_get_route to silc_server_route_get.
6835 * Added id_string and id_string_len fields into SilcServer to
6836 include encoded ServerID for fast comparing without excess
6837 encoding of the ID's.
6839 * Cleaned up WHOIS command on server side. Added following static
6842 silc_server_command_whois_parse
6843 silc_server_command_whois_check
6844 silc_server_command_whois_send_reply
6845 silc_server_command_whois_from_client
6846 silc_server_command_whois_from_server
6848 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6849 arguments in command replies. All command functions should be
6850 updated to use this macro.
6852 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Minor typo fixes on command reply handling on server.
6856 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Added silc_server_command_add_to_channel internal routine to add
6859 the client to the channel after router has created the channel and
6860 sent command reply to the server.
6862 * Added generic silc_server_send_command to send any command from
6865 * Use static buffer with ID rendering instead of duplicating data.
6867 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * Fixed a channel user mode bug when joining to a channel server gave
6870 everybody channel founder rights, oops.
6872 * We mark ourselves as the router of the incoming server connection
6873 if we are router ourselves. This way we can check in some packet
6874 sending functions whether it is locally connected server. For
6875 incoming router connections we put NULL.
6877 * For router sending packets locally means now always sending the
6878 packet cell wide; to local clients and local servers. For normal
6879 server sending packet locally means sending it to only local
6882 * Fixed the JOIN command to really work in router environment. If the
6883 channel is created it is always created by the router. Router is
6884 also responsible of making the initial joining to the channel,
6885 sending JOIN notify to the sending server and distributing
6886 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6887 does not exist server doesn't do anything else but forward the
6888 command to the router which performs everything.
6890 * Added silc_server_send_channel_key function to send the Channel Key
6893 * Added silc_server_create_channel_key to create new channel key. The
6894 channel key is now re-generated everytime someone joins or leaves
6895 a channel, as protocol dictates. Note: channel->key_len is the
6898 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6901 packet_receive.[ch] to separate packet sending and receiving
6902 routines. The server.[ch] now includes everything else including
6903 actual packet processing (writing and reading data) and other
6906 Renamed silc_server_private_message_send_internal to
6907 silc_server_send_private_message. The routine is still though
6908 used only to relay private messages as server does not send
6909 private messages itself.
6911 Renamed silc_server_new_channel to silc_server_create_new_channel
6912 and added new function sicl_server_new_channel that handles the
6913 incoming New Channel packet. Added also new sending function
6914 silc_server_send_new_channel to send New Channel Payload.
6916 * Added new function silc_server_notify to process incoming notify
6917 packet to the server/router. Server may then relay the notify
6918 to clients if needed.
6920 * Added new function silc_server_new_channel_user to process incoming
6921 New Channel User packet. Router will redistribute the packet and
6922 send JOIN notify to its local clients and locally connected servers
6923 if needed. Normal server will send JOIN notify to its local client
6924 on same channel when received this packet. Added also corresponding
6925 sending function silc_server_send_new_channel_user to sent the
6928 * Added boolean route argument to send_notif_to_channel and
6929 packet_send_to_channel functions to attempt to route the packet
6930 if it is TRUE and send only locally if it is FALSE.
6932 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * silc_server_replace_id now broadcasts the received replace ID
6935 packet if it is not broadcast packet already. The router must
6936 broadcast to inform other routers about changed ID.
6938 * Added backpointer to server's router into SilcServer context in
6939 silcd/server_internal.h.
6941 * Fixed silc_server_packet_broadcast to send correct broadcast
6944 * The channel key is now distributed to the local client as soon
6945 as it is received from the router (in router environment) so that
6946 no other packet may be sent for the channel until client has
6949 * silc_server_remove_channel_user now broadcasts the received
6950 Remove Channel User packet if it is not broadcast packet already.
6951 The router must broadcast to inform other routers about removed
6954 * Added users field into SilcPacketContext that is a reference count
6955 of the context. One can increase the reference count by calling
6956 silc_packet_context_dup which is now changed to just increase the
6957 reference count instead of duplicating the data. The reference
6958 count is decresed by calling silc_packet_context_free that will
6959 free the data after the reference count hits zero.
6961 For now on the packet context and everything allocated into it
6962 (including the raw packet from network) must be freed by calling
6963 the new silc_packet_context_free function. Added also new function
6964 silc_packet_context_alloc that must be used now to allocate the
6965 context. This also means that if a routine is asynchronous from
6966 silc_[client/server]_packet_parse_type the packet context must
6967 be duplicated by calling silc_packet_context_dup. Otherwise it
6968 gets free'd after silc_[client/server]_packet_parse_type returns.
6969 Also, one must remember that if packet is duplicated then its
6970 reference count must be decresed by calling the free function as
6971 many times as it was duplicated.
6973 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6974 from both client and server.
6976 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Made joining to a channel working in router environment.
6980 * Cleaned up JOIN command on server side and create function
6981 silc_server_command_join_channel internal routine to make the
6984 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Changed silc_command_pending list to SilcDList. Also, added
6987 `ident' field to SilcServerCommandPending structure to identify
6988 the reply and to call correct callback.
6990 Added silc_server_command_pending_check function to replace the
6991 corresnponding macro. The silc_command_pending list is not
6994 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6995 to set identifier to previously allocated Command Payload. It
6996 is used to set identifier for command when resending Command
6999 * Added silc_command_payload_encode_payload to encode Command
7000 Payload buffer from SilcCommandPayload structure.
7002 * Added silc_argument_payload_encode_payload to encode Argument
7003 payload buffer from SilcArgumentPayload structure.
7005 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Changed WHOIS command to support router connection on server side.
7008 The whois request is always sent to router unless the server is
7009 standalone server. After server has received the reply from the
7010 router will it send the reply to the client.
7012 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7013 broadcast received broadcast packet. The function is used only
7014 by router. The broadcast packet is always sent to the router's
7017 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7018 render given ID to printable string, for log files for example.
7020 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Made basic router to router connections working. At least they
7023 can now connect to each other but nothing really works the way
7024 they are supposed - yet.
7026 * Added new initiator token to RouterConnection configuration
7027 file in silcd/serverconfig.[ch]. It is used to tell whether we
7028 are the initiator to the remote router or whether we'll expect
7029 the other end to connect.
7031 * Moved registering of listener task to silc_server_init, hence
7032 the server starts listenning as soon as it is run, even if it
7033 does not have connections to other routers. Let's see how well
7036 * Changed default connection retry timeouts for more suitable in
7039 * Removed cipher and such arguments from silc_idlist_add_client
7040 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7041 Added new function silc_idlist_add_data to add the keys and stuff
7044 * Added SilcIDListData structure and added it to SilcClientEntry
7045 and SilcServerEntry as their first field in the structure. This
7046 way we can explicitly cast the ID entries to the SilcIDListData
7047 structure and get common data for the entries. In past, we had
7048 to first check what type of connection it is and then cast it to
7049 correct ID entry type. Now, we can directly cast the opaque
7050 pointer to the SilcIDListData (no matter what ID entry it actually
7051 is) and get the data needed.
7053 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7055 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7056 in some circumstances even if threre were timeout tasks, though not
7057 IO tasks, but tasks anyway. Now fixed.
7059 * Defined SilcServerConnection structure to hold connection specific
7060 stuff about directly connected servers and routers. The definition
7061 is currently in silcd/server_internal.h. I thought about having
7062 a bit more important role fro this struct but for now it is used
7063 only when connecting to other server (or router actually).
7065 * Added connecting retry support in server when connecting to
7066 router(s). The retry feature implement exponential backoff
7067 algorithm. Also, added SilcServerParams structure to hold default
7068 parameters for server. For now, it include these retry settings
7069 and are hard coded. After server is moded to be as Silc Server
7070 Library this structure will be more important.
7072 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Changed client librarys channel->clients table to SilcList and
7075 changed code accordingly.
7077 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7079 * Changed client's channel table to SilcList and changed code
7080 accordingly. Also changed SilcChannelClientEntry to include back-
7081 pointer to the channel so that client entry can use that structure
7082 as list as well and we have fast cross-reference to the channel.
7083 This change dramatically decreased the complexity of channel
7084 handling with client entry and vice versa (removed one extra
7085 loop when searching for channel entry from many functions).
7087 * Changed server->sim from table to SilcDList and changed code
7090 * NAMES command can now be used from user interface. It will show
7091 the user list on the channel, neatly.
7093 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7094 Code now saves realname of the user if it becomes available.
7096 * Renamed configure.in to configure.in.pre and made ./prepare
7097 script to automatically add correct version string to
7098 configure.in which it creates from configure.in.pre.
7100 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * NAMES command reply now shows users mode with the nickname when
7105 * Moved silc_client_ch[u]mode[_char] functions from
7106 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7107 place sucks, they are utility functions and should be in some
7110 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7112 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7115 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Added TRQ (efficient deque and list library) into lib/trq. This is
7120 a very good list library that is currently used in the SILC. Defined
7121 SilcList API over the library because I didn't like the API very
7122 much. See lib/trq/silclist.h for the API and examples of how to
7123 use the API. Fixed various places in the code to use the new
7124 SilcList API. The SilcList is meant for lists that has a structure
7125 already defined as a list. It is not suitable to add just some
7126 context to the list (in TRQ, the context is the list actually).
7128 So, I defined SilcDList that can be used for the purpose where
7129 predefined list structure does not exit. This can be used as
7130 such list. Now some context just can be added to the SilcDList.
7131 Currently this list is not used in the SILC just yet, though there
7132 are a lot places where this can replace dynamically allocated
7133 tables and I will fix these places, later, to use SilcDList.
7134 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7135 and use TRQ internally).
7137 Also fixed some annoying warning messages that the original TRQ
7138 code generated. Also minor changes to TRQ's Makefile.in.
7140 * Added support for querying by Client ID to both WHOIS and
7141 IDENTIFY commands into server, as required by the protocol.
7143 * Removed method function pointers from SilcBuffer structure. They
7144 weren't used to anything and just increased the context size for
7145 no good reason. This change also made silc_buffer_alloc and
7146 silc_buffer_free functions inline functions.
7148 * Disabled command flooding detection support until it's fixed so
7149 that it accepts commands in but does not execute them more than once
7152 * Added silc_net_localhost(), to return local hostname, into
7153 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7154 that must be initialized before calling silc_client_init.
7156 * Added new function: silc_server_send_notify_on_channels to send
7157 notify messages to all channels client has joined. It is assured
7158 that the message is sent only once per client.
7160 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7161 lib/silcutil/silcutil.[ch] as silc_format function. The new
7162 function is generic and is used by server as well, not only by
7163 the logging routines.
7165 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7166 the provided version string was not acceptable. Added new function:
7167 silc_ske_check_version into lib/silcske/silcske.h. The function
7168 must be implemented by the application (client or server) and it
7169 does not reside in the SKE library. The function checks the version
7170 string remote end sent.
7172 * Added back pointers (to opaque context and to SilcSocketConnection)
7173 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7175 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7176 duplicate packet context structure.
7178 * Changed `notify' client operation to send same arguments as client
7179 receives from server except for ID's. ID's are mapped to correct
7180 ID entry and that is returned. Also, if channel entry is not sent
7181 by server but the notify is for channel the channel entry is sent
7182 to application (otherwise application doesn't know that it is for
7183 channel (library gets it from packet's Destination ID)).
7185 * Added silc_client_remove_from_channels into client library to
7186 remove a client from all channels it has joined to. Used when
7187 received SIGNOFF notify from server. Added also new function
7188 silc_client_replace_from_channels to replace old ID entry with
7189 new ID entry on all channels. Used when received NICK_CHANGE
7192 * Fixed ID Cache list handling in silc_idlist_get_client in
7193 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7194 to get (or query) client by ID.
7196 * Updated TODO list.
7198 * Added connection authentication status message defined by the
7199 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7200 support for these into the code in client and server side.
7202 * Added generic function silc_client_send_command to send any command
7203 with variable argument list. Application should use this function
7204 to send commands if the command functions provided by the library
7205 does not suite for the application's user interface needs.
7207 * Added new `failure' client operation. Application is notified about
7208 received failure packet if client is executing a protocol. In this
7209 case the protocol's execution has failed.
7211 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7212 is required by the protocol.
7214 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7215 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7218 * Added status flag to SilcSKE object to indicate realtime status
7219 of the SKE protocol.
7221 * Application receives now exactly same command reply arguments as
7222 the library receives from server. However, if ID is received the
7223 corresponding ID entry is returned to the application (eg. Client
7224 ID is mapped to correct SilcClientEntry entry and that is returned).
7225 Changed command_reply client operation due to this change.
7227 * Changed all ID's in commands and in command replys as ID Payloads.
7228 Change affected both client and server side codes.
7230 All ID's sent in SILC network (with execption of ID's in SILC
7231 Packet header) are sent in ID Payload to support variable length
7234 * Server now notifies nick changes and notifies all clients on
7235 the channels about the new nickname (about the new Client ID,
7238 * Implemented CMODE command to change channel modes. Supports all
7239 channel modes defined by the protocol specs except ban and invite
7240 lists. (Also, private channel key mode is supported but support for
7241 setting private channel key in client is missing, thus, this mode
7242 has no effect on client side (except that server requires that the
7243 client uses private channel key and normal channel traffic does not
7246 Also, invite mode works per se, but INVITE command does not work
7247 yet correctly, so you can set channel as invite only channel but
7248 inviting clients to the channel does not work (it is yet to be
7249 thought what's the best way to do it).
7251 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7252 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7253 Implemented CUMODE command to change user's mode on the channel.
7254 Supports all modes defined by the protocol specs.
7256 * Added NAMES command reply to return users modes on the channel.
7258 * Removed unnecessary and slow ciphers from lib/silccrypt.
7260 * Set SO_KEEPALIVE option to connection sockets by default.
7262 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7264 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7265 redefined the Notify Payload into protocol specs.
7267 * Added silc_id_payload_parse_id to get ID directly from raw
7270 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7273 accept searching by Client ID as well.
7275 * Added support for LEAVE and SIGNOFF notify types in client library.
7277 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7278 to parse ID Payload from raw data.
7280 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Added flags parameter into silc_ske_assemble_security_properties
7283 function in lib/silcske/silcske.[ch].
7285 * Changed notify client operation to fit better for notify messages
7286 sent by server. The notify payload received from server is now
7287 passed to the application (after parsing it to SilcNotifyPayload).
7288 It is application's responsibility to retrieve the arguments
7289 from the payload and show the message the way it wants. The message
7290 sent by server is implementation specific.
7292 * Changed public keys to comply with the protocol specification.
7293 Old public keys are not supported anymore and are not compatible.
7295 * Removed nickname from Channel Payload as the latest draft removed
7296 it. The client must resolve the nickname from the NAMES command
7297 reply received when it joined the channel.
7299 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7301 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * Fixed some errors in protocol specification drafts.
7305 * Created lib/silccore/silcnotify.c to implement Notify Payload
7306 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7307 generic payloads described by protocol specifications. The file
7308 includes implementations for ID Payload and Argument Payload.
7310 * Changed Command Payload implementation to use the new Argument
7311 Payload. Changed command_xxxx_payload to command_payload_xxxx
7312 to comply with SILC coding conventions.
7314 * Added suppport for Argument Payload handling in Notify Payload
7315 implementation as protocol requires it. Added the new support
7316 into server and client lib as well.
7318 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Added support for multiple nicknames on same channel. [n] is
7321 added locally to the nickname if there are more than one same
7322 nicknames on the channel.
7324 * Server now sends all nicknames that matched WHOIS request.
7325 Client also shows the list received from server.
7327 * Added TOPIC command to client side. User can now set and show
7328 current topic on channel.
7330 * Added MOTD command to client and server. Also, server sends the
7331 motd when client connects to the server.
7333 * Changed version strings to comply ISO 8601.
7335 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7337 * Fixed protocol error handling in client library. It should now
7338 cope even if the SKE fails for some reason.
7340 * Made new protocol specification drafts for submitting to IETF.
7342 * Implemented TOPIC command to server in silcd/command.c.
7344 * Added two new notify types into lib/silccore/silcnotify.h:
7345 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7346 notify nickname change and topic setting/change on a channel.
7348 * API change of command_reply operation in client library. The
7349 application gets now the status type received from server as well.
7351 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7353 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7355 * Cras fixed and optimized the packet handling even further and
7356 it should work now. Minor change to the prototype of function
7357 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7359 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Added new function into lib/silcutil/silcschedule.[ch]:
7362 silc_schedule_with_fd to select() a specified fd. The function
7363 returns after timeout expires or data arrives or goes. The
7364 function is used by packet routines to wait that all data is
7365 received from network.
7367 * Fixed data reading from network in lib/silccore/silcpacket.c.
7368 The code now assures that all data is read from the fd and then
7369 continues packet processing. This was a bug fix since the code
7370 used to drop some data in some circumstances.
7372 * Added new function into lib/silcclient/client.[ch]:
7373 silc_client_start_key_exchange to start key exchange after
7374 connection has been established to server. The code internally
7375 now uses this funtion but its main purpose was to provide it
7376 for applications that perform their own connecting. After
7377 application has created a connection it merely calls this
7378 function to start the key exchange between client and server.
7379 The library takes care of everything else after that.
7381 Updated also lib/silcclient/README to explain the usage of
7384 * Do not send to application information that connection has
7385 been established. Application gets notified it by connect
7388 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * Applied cras's patch to add silc_schedule_one function. The
7391 function runs scheduler once and returns.
7393 * Fixed the scheduler after cras messed it up. The timeout
7394 handling works now as it's supposed to work.
7396 * Added into lib/silccore/ silcnotify.h to include notify
7397 message types support. Changed silc_server_send_notify*
7398 functions, in server.[ch], to support those new notify types.
7399 Added the support for the notify types into client library,
7400 as well. Added new notify client operation into ops.h in
7403 * Changed silc_server_packet_send_to_channel to send normal
7404 packets instead of just channel message packets. The function
7405 is now used to send the notify packets to channels. It is not
7406 used to send channel message packets anymore, as server never
7409 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7410 va_arg()s as it seems to require it nowadays. I guess, if SILC
7411 is compiled with older va_arg() the new code should work anyway.
7413 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Splitted core library. Core library (lib/silccore) includes
7416 now only SILC protocol specific core (and common) components.
7417 Created new utility library (lib/silcutil) that includes more
7418 generic purpose stuff. The stuff for util library was taken
7419 from the old core library. This was minor and easy split.
7421 * Created SILC Client Library (lib/silcclient) that includes
7422 implementation of the SILC client without user interface. This
7423 was major move from silc/ directory. The code has been changed
7424 so that it is transparent towards the user interface. The
7425 silc/ directory includes now the same user interface as before
7426 and it uses the new client library. Read lib/silcclient/README.
7427 Basicly, the client library performs everything else related
7428 to SILC except user interface handling. Also, configuration
7429 files are considered to be part of user interface and library
7430 does not handle them.
7432 This change also changed a lot of structures, function naming etc.
7433 Most important change was that SilcClientWindow object was
7434 renamed to SilcClientConnection in the client library. Created
7435 also new file lib/silcclient/ops.h. Also added new files
7436 silc/local_command.[ch] and silc/client_ops.[ch].
7438 All these changes were made to make it easier for user interface
7439 designers to create what ever user interface for the SILC client
7442 It is also expected that the server will be moved to lib
7443 directory as well and SILC Server Library will be created;
7444 sometimes in the future.
7446 * Removed Local commands from lib/silccore/silccommand.h as
7447 they are application specific and new client library does not
7448 handle any of those anymore.
7450 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7451 old client implementation in silc/.
7453 * Added support for callback functions in SILC_LOG_* macros.
7454 Application can now set its own callbacks that will be called
7455 instead of using the default functions that will always print
7456 the debug messages to stderr (or stdout). Also, debugging can
7457 now be disabled by setting silc_debug to FALSE and re-enabled by
7458 setting it to TRUE. Note, that logging will still work even
7459 if debugging is disabled.
7461 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7462 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7463 silc_log_reset_debug_callbacks.
7465 * To enable debugging in silc client one must give now -d
7466 option on command line.
7468 * Changed silc_schedule_init to automatically allocate task queues
7469 if they are not allocated before calling it.
7471 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Added GMP 3.1 into math library.
7475 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7478 a channel in SILC network. The packet is used by servers and
7479 routers to notify other routers that user has left a channel.
7480 This little feature was missing until now. Added the feature
7481 to protocol specification as well.
7483 Added functions: silc_server_send_remove_channel_user and
7484 silc_server_remove_channel_user into server.[ch].
7486 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7487 lib/silccore/silcpacket.h. However, they are not implemented
7490 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Fixed joining to a channel and sending channel messages
7493 between server and router. The channel message sending should
7494 now work inside a cell.
7496 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7498 * Fixed the private message sending between server and router.
7499 The private message sending should now work inside a cell.
7501 * Added silc_server_replace_id into server.[ch] to replace
7502 existing ID in the SILC network.
7504 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7505 and silc_idlist_replace_server_id into idlist.[ch] in server.
7507 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7509 * Fixed the server to server connections. Server can again now
7510 connect to router. Router to router connections probably does
7513 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added dynamic protocol registering support. Now protocols can
7516 registered and unregistered on the fly. Patch by cras.
7518 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7520 * Added lib/contrib directory to hold routines that some platforms
7521 don't have but are needed by SILC.
7523 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7524 into lin/contrib to provide getopt() and getopt_long() for
7525 those who don't have it.
7527 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7529 * Added AWAY command to client. When away message is set and
7530 client receives a private message packet the client automatically
7531 replies to the sender with the away message.
7533 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7534 bug seemed to be the cause of recent problems when compiling
7537 * Added version detection support to SKE protocol specification
7538 and added the new changes to the SKE implementation as well.
7539 There were other minor changes in the SKE protocol as well.
7541 Many changes in lib/silcske/silcske.[ch] and in
7542 lib/silcske/payload.[ch].
7544 * Added ^U functionality, clear input line. Patch from cras.
7546 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7548 * Mainly small bugfixes on core library. Fixed some debugging
7549 logging and buffer overflow in silclog.c.
7551 * Updated config.sub and config.guess on the distribution tree.
7553 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7555 * Added command lagging support in server. Client may execute
7556 commands now only once in two seconds.
7558 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Optimized packet reception. MAC computation and checking is now
7561 also more optimized. A lot previously duplicated code is now
7562 used as generic by both client and server.
7564 * Fixed key pair generation in clientutil.c
7566 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7568 * Added into lib/silccore/silcbufutil.[ch] new function;
7569 silc_buffer_realloc.
7571 * Moved generic packet sending/encryption functions to
7572 lib/silccore/silcpacket.[ch] from client and server. Some
7573 rewriting of the functions.
7575 * Moved all generic packet reception/decryption functions to
7576 lib/silccore/silcpacket.[ch] from client and server. The
7577 packet processing is now much cleaner in both client and server.
7578 These were major changes in both client and server.
7580 * Created many common functions in server to do packet sending.
7581 Previously code were duplicated a lot, this has been removed
7584 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7586 * Rewrote major parts of the ID cache system. Don't know
7587 whether it is better now or not but at least the API is more
7590 * Major rewrite on ID cache stuff on client because of the ID
7591 cache API changes. Added idlist.c to client.
7593 * Also major rewrite on ID cache stuff on server as well.
7594 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7595 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7596 in hand, instead they are all put into the ID cache system now.
7597 All server_idlist_* routines uses ID cache now instead of
7598 traversing its own lists (those lists does not exist anymore).
7599 SilcIDList though still exists. Also, SilcXXXEntry's are
7602 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7604 * Finally made the SKE implementation compliant to the protocol
7605 specification. All mp integers are now binary encoded as
7606 opposed being HEX encoded.
7608 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7611 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7612 functions: silc_[encode/decode]_pem. Also added function
7613 silc_encode_pem_file to PEM encode with newlines ('\n') for
7616 * SILC public keys are now encoded either PEM or binary. Same
7617 option is for private keys as well. By default private keys
7618 are binary encoded and public keys PEM encoded. Silly HEX
7619 encoding were removed.
7621 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7622 function to create fingerprints.
7624 * Fixed a bug in SHA1; does not change the original data anymore.
7626 * Partly implemented INFO command on client and server side.
7627 Fixed CLEAR command. Changes to SERVER command; show current
7628 server(s) when giving command without arguments. Added
7629 VERSION command to client.
7631 * Added check to server that unregistered connections cannot
7632 execute commands (unless it is specificly allowed).
7634 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Fixed screen refresh.
7638 * Fixed channel joining bug from client. On some circumstances
7639 client tried to join to a channel it had already joined.
7641 * Added public key verification process into client's protocol.c.
7642 The client now verifies the public key from user and saves
7643 it into ~./silc/serverkeys/ directory.
7645 Added into: clientutil.[ch]: silc_client_verify_server_key.
7647 * Changed SKE protocol's silc_ske_initiator_finish function
7648 to accept callback function that verifies the received public
7649 key. Removed old silc_ske_verify_public_key function.
7651 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7654 silc_pkcs_private_key[_data]_set.
7656 * Made the password and public authentication more cleaner in
7657 server's protocol.c.
7659 * Removed historic and obsolete protocol `channel_auth' from
7660 both client and server.
7662 * Removed wrong way of sending command status messages from
7663 server to client in server's command.c. The old way violated
7664 protocol specification.
7666 Changes to silccore/silccommand.[ch]: removed
7667 silc_command_encode_status_payload -> not needed anymore,
7668 changed silc_command_encode_payload_va to accept extra
7669 argument on variable argument list. The argument type must
7670 now be provided to the function. Also, added new function:
7671 silc_command_encode_reply_payload_va which is same as
7672 normal command_encode_payload_va except command status type
7673 is provided as extra argument.
7675 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Added ~./silc directory handling. The directory includes the
7678 public and private keys for the client.
7680 Added silc_client_check_silc_dir, silc_client_create_identifier
7681 and silc_client_load_keys.
7683 * Implemented SILC protocol compliant public key. Added public
7684 and private key saving to and loading from files.
7686 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7687 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7688 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7689 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7690 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7692 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7693 silc_pkcs_load_[public/private]_key.
7695 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Added silc_server_get_route (route.[ch]) to get connection
7698 data for the fastest route for given ID.
7700 * Implemented INVITE command on client and server. The command
7701 were re-defined in the SILC Protocol Specification and the
7702 implementation now complies with the specification.
7704 * Implemented PING command on client and server.
7706 * Implemented NAMES command on client and server. The server side
7707 supports currently only normal server not router server yet.
7708 Some changes to NAMES definition in SILC protocol specification.
7710 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7712 * Implemented LEAVE command on client and server.
7714 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7715 again. This change was made to the protocol as well. Server
7716 should not violate the protocol specification anymore.
7718 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7721 was tested. SOCKS4 was not but should work anyway.
