1 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed silc_net_gethostbyaddr to correctly resolve by
4 address. Affected file lib/silcutil/silcnet.c.
6 * Fixed the notify relaying to client. The HMAC to be used
7 with relayed packets ws wrong and caused decryption failure
8 at the client end. Affected file is silcd/packet_receive.c.
10 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
12 * Created new branch silc_protocol_1_0_branch.
14 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
16 * Changed the silc_server_config_* routines to be SilcServer
17 independent. They are now officially application specific code
18 and not part of generic server implementation. Affected files
19 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
21 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Added automatic referencing of config context in the
24 silc_server_config_alloc, and automatic unreferencing in the
25 silc_server_config_destroy. Affected files are
26 silcd/serverconfig.[ch], silcd/silcd.c.
28 * Fixed the silc_log_quick handling in the logging routines.
29 It didn't log quickly when it was TRUE. Affected file is
30 lib/silcutil/silclog.c. Also the flush delay was set even
31 if it was 0 in config file. Affected file is
34 * Added support for changing key pair of the server in rehash.
35 Affected file silcd/server.c.
37 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
39 * Fixed the TOPIC_SET notify to not cras. It changed the topic
40 too early, before getting the channel entry. Affected file
41 is silcd/packet_receive.c.
43 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
45 * Added functions silc_server_config_[ref/unref], these are used
46 to prevent that the config object is destroyed.
48 No longer directly affect global variables silc_log_quick and
49 silc_log_delay, they are first cached inside the config object
50 and then applied with silc_server_config_setlogfiles().
52 silc_server_config_set_defaults() is now internal to
53 serverconfig.c, there are no reasons to show this internal stuff
56 Affected files are silcd/serverconfig.[ch].
58 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
59 fprintf's to stderr, since some code may be executed again after
60 the server went into the background. Affected files are
63 * Added rehash support. Added function silc_server_rehash() that
64 will perform all the basic tasks of the rehashing procedure.
66 * Added command line option `-x, --hexdump'. This will enable the
67 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
68 The option `--hexdump' implies `--debug'.
70 * Fixed a bad bug in the logging APIs (silcutil library) where
71 the application would crash after calling silc_log_reset_all().
73 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed the KICKED notify handling in client library to
76 correctly remove the channel and all entries from the
77 channel when I was kicked. This bug crashed the client.
79 Fixed yet another but in KICKED notify handling to remove
80 the kicked client correctly from the channel.
82 Affected file is lib/silcclient/client_notify.c.
84 * Fixed a minor bug in looking up correct client entry
85 in KICKED notify in server. Affected file is
86 silcd/packet_receive.c.
88 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
89 sources correctly to distribution. Fixes --with-gmp option.
91 * Removed the manual rehashing from ID Cache, and changed it
92 to use the SILC Hash Table's auto rehash feature. Affected
93 file is lib/silccore/silcidcache.c.
95 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
97 * Fixed a bug in the silc_client_nickname_format function that
98 handles the multiple same nickname formatting. Two clients
99 with same nickname caused problems after the first one left
100 and rejoined. It didn't format the nickname correctly.
101 Affected file is lib/silcclient/idlist.c.
103 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Don't change the topic if olod topic is same as new one.
106 Affected file is silcd/packet_receive.c.
108 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
110 * Added cross-reference support to the SILC Documentation
111 generator. All types across all HTML files are now cross-
112 referenced. Affected files util/robodoc/generator.c and
113 scripts/silcdoc/silcdoc.
115 * Added file lib/silcutil/silctypes.h to include all the
116 arithmetic type definitions and some macros. Removed
117 includes/bitmove.h and moved macros to silctypes.h.
119 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
121 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
123 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Added `type' argument to silc_id_payload_parse_id function which
126 now returns the type of the ID to the sent pointer. Affected
127 file is lib/silccore/silcid.[ch].
129 * Added check for CMODE_CHANGE notify type that mode change is
130 allowed by the sender. Affected file silcd/packet_receive.c.
132 * Added check for CUMODE_CHANGE notify type that mode change is
133 allowed by the sender. Affected file silcd/packet_receive.c.
134 Added the ID type as CUMODE_CHANGE notify type as argument
135 to the `notify' client operation. Affected files are
136 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
138 * Added function silc_client_add_server to the client library.
139 Added support for resolving also channel and server info when
140 received unknown entity in notify packet. Affected files are
141 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
143 * Added function silc_command_get_status to return the command
144 status from the command reply's argument payload. Affected files
145 are lib/silccore/silccommand.[ch].
147 * Added check for KICKED notify type that the kicking is
148 allowed by the client. Affected file silcd/packet_receive.c.
150 * Created function silc_get_input which can be used to get input
151 (echo on or off) from user on command line. Affected files are
152 lib/silcutil/silcutil.[ch].
154 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Optimized silc_server_packet_relay_to_channel function.
157 Added new function silc_channel_message_payload_encrypt which
158 can be called directly if channel message payload needs to
159 be encrypted and is already encoded (no need to call _encode
160 function). Packet relaying is now done by router without any
161 extra memory allocations. Affected files are
162 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
165 * Fixed the INVITE notify handling. It took wrong arguments
166 as invite list and invite delete. Affected file is
167 silcd/packet_receive.c.
169 * Added check for TOPIC_SET notify type that the topic change is
170 allowed by the client. Affected file silcd/packet_receive.c.
172 * Added check for INVITE notify type that inviting is allowed by
173 the client. Affected file silcd/packet_receive.c.
175 * Changed the silc_server_client_on_channel to return the
176 SilcChannelClientEntry as well. Moved the function
177 silc_server_check_cmode_rights to server_util.[ch].
178 Affected files are silcd/server_util.[ch], silcd/command.c.
180 * Added function silc_server_check_umode_rights to check whether
181 changing client's user mode is allowed. Added check for
182 UMODE_CHANGE notify type that the umode change is allowed
183 by the client. Affected files are silcd/server_util.[ch],
184 silcd/packet_receive.c and silcd/command.c.
186 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
188 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
189 ID length. It ignored that ID can be IPv6 based as well.
190 Affected file lib/silccore/silcpacket.h.
192 * Fixed the silc_id_id2str and silc_id_str2id to take the
193 IPv6 address offset's into consideration. Affecte file is
194 lib/silccore/silcid.c.
196 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
198 * Fixed the internal Unix scheduler functions to check for
199 NULL context they may receive. The affected file is
200 lib/silcutil/unix/silcunixschedule.c.
202 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
204 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
205 can specify different directory with --home command line
206 parameter. Affected files irssi/src/silc/core/client_ops.c,
209 * SILC-specific commands aren't now executed if the active server
210 isn't of SILC-type, so there won't be problems with having
211 IRC and SILC protocol support in same client. Affected files
212 irssi/src/silc/core/silc-channels.c, silc-servers.c,
215 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
217 * Improved the signal support in SILC Schedule. Added new
218 function silc_schedule_signal_call which is used by application
219 to mark a signal to be called. It is now safe to perform
220 any kind of tasks in signal callbacks since it is guaranteed
221 that the application specified signal callback is called
222 after the signal is over. Affected files are
223 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
225 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
227 * Added `name' field to SilcChannelPrivateKey to represent
228 application given name for the key. Moved also the context from
229 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
230 Added the `name' argument also to the function
231 silc_client_add_channel_private_key.
233 Added function silc_client_current_channel_private_key to set the
234 current channel private key in use.
236 Added "change" command to KEY command which can be used to change
237 the current channel private key. Bound the command also to
240 Also affected files lib/silcclient/client_channel.c,
241 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
243 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Added silc_rng_get_byte_fast function in to the
246 lib/silccrypt/silcrng.[ch].
248 * Changed the interface of silc_packet_assemble and the
249 silc_packet_send_prepare. If silc_packet_assmble is now
250 called the application does not call silc_packet_send_prepare
251 because the library will call it automatically. These
252 interfaces now also return a reference to the outgoing buffer
253 which includes the assembled packet, which the application can
254 use to encrypt the packet.
256 Affected files are lib/silccore/silcpacket.[ch],
257 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
258 silcd/packet_send.c, server_backup.c and packet_receive.c.
260 * Fixed a packet sending bug on very high load, where outgoing
261 packet queue wasn't handled correctly and packets got corrupted.
262 Affected files are lib/silcutil/*/silc*sockconn.c,
263 lib/silcclient/client.c and silcd/server.c.
265 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Added macro SILC_PACKET_DATALEN which can be used during
268 packet assembling to check whether the data to be added to
269 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
270 len is truncated until it fits it.
272 Added checks for maximum length of channel message payload and
273 private message payload also.
275 Added checks for maximum packet length in server and in
278 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
279 lib/silcclient/client.c, lib/silccore/silcchannel.c and
280 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
281 lib/silcclient/client_prvmsg.c.
283 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
285 * Added silc_server_packet_queue_purge call to the
286 silc_server_disconnect_remote to assure that all data in the
287 queue before disconnecting is sent to the network. Affected
290 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
292 * Added the deleting of server's own ID cache entry to the
293 silc_server_free function. Free also everything else that
294 has been allocated in silc_server_init. The affected file
297 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Added functions silc_parse_version_string, silc_version_to_num,
300 and silc_ske_parse_version to parse SILC protocol style version
301 strings. Affected files lib/silcutil/silcutil.[ch] and
302 lib/silcske/silcske.[ch].
304 * Added new configuration params: version_protocol, version_software
305 and version_software_vendor to specify what version the remote
306 host must at least be to be able to connect to server. The vendor
307 string can be regex matched too. Added new function
308 silc_server_connection_allowed to check maximum number of allowed
309 connections, and allowed versions for incoming connections.
310 Affected files are silcd/server.c, server_util.[ch] and
313 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
315 * Added preliminary support for signals in scheduler. The
316 signals we care about are now blocked always when the scheduler
317 is locked. This way we can synchronise the use of signal with
318 scheduler. It is guaranteed that when signal occurs the scheduler
319 is not locked, and thus new tasks can be safely added to the
322 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
323 to silc_schedule_internal_init and silc_schedule_internal_uninit.
324 Added new platform specific routines
325 silc_schedule_internal_signals_[un]block and
326 silc_schedule_internal_signal_[un]register.
328 Added new functions to SILC Schedule API:
329 silc_schedule_signal_[un]register. Each signal that application
330 is going to use should be registered to the scheduler.
332 Affected files are lib/silcutil/silcschedule.[ch],
333 lib/silcutil/*/silc*schedule.c.
335 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
337 * Check for unauthenticated client and server in the
338 silc_server_new_client and silc_server_new_server functions.
339 Affected file silcd/packet_receive.c.
341 * Added function silc_string_is_ascii to check whether given
342 string is 7-bit ASCII string. Affected files are
343 lib/silcutil/silcutil.[ch].
345 * Added function silc_id_is_valid_server_id into the
346 silcd/serverid.c and added checking for valid Server ID's in
347 silc_server_new_server. The Server ID must always be based
348 on the server's public IP address.
350 * Added logging of DISCONNECT packet message in the server.
351 Affected file silcd/server.c.
353 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
355 * Changed all library interfaces that use Global RNG to also
356 accept SilcRng as argument. Affected files are
357 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
358 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
359 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
360 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
363 * Added function silc_pkcs_generate_key to the
364 lib/silccrypt/silcpkcs.[ch] for applications so that they
365 don't need to do pkcs->pkcs->init calls anymore.
367 * Remove SilcSocketConnection from the SFTP API since it really
368 wasn't needed there. The application has the information
369 saved in its contexts anyway and the SFTP layer doesn't need
370 know about it. Affected files lib/silcsft/silcsftp.h and
371 lib/silcsftp/sftp_[server/client].c.
373 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
374 The SilcSimContext is not SilcSim.
376 * Fixed possible buffer overflows in silc_id_render in the
377 lib/silcutil/silcutil.c.
379 * On EPOC the global crypto module lists are not used at all
380 in the crypto library. Added support for using the constant
381 algorithm list on EPOC. Affected files are
382 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
385 * Fixed the handling of third parameter of KICKED notify, since
386 it was mistakenly updated to SILC Protocol 1.0 even though it
387 is to be included in 1.1. Since it is not in 1.0 it is not
388 mandatory, and this fix now handles it only if it is provided,
389 and it is not error if it is not provided. Affected file
390 lib/silcclient/client_notify.c.
392 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
394 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
395 client. Affected file irssi/src/silc/core/client_ops.c.
397 * Merged with Irssi 0.8.4 from irssi.org CVS.
399 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
401 * Check for valid socket connection in client entries before
402 sending any messages. Fixes a crash, but doesn't fix some
403 other underlaying bug that is lurking there. Affected
404 file silcd/packet_send.c.
406 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
408 * $usermode, $cumode and $cumode_space expandos shouldn't do
409 anything with non-SILC server records. Affected file
410 irssi/src/silc/core/silc-expandos.c
412 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
414 * Fixed the silc_net_check_[host/local]_by_sock to support
415 IPv6 bound sockets as well. Now they can return IPv6 addresses
416 as well. Affected file lib/silcutil/silcnet.c.
418 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
419 Affected lib/silcutil/unix/silcunixnet.c.
421 * Fixed ID rendering (at least on some platforms, not NetBSD)
422 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
424 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
426 * Added silc_hash_public_key and silc_hash_public_key_compare
427 functions to be used with SilcHashTable. They can be used to
428 hash public keys and compare public keys in hash table. Affected
429 file lib/silcutil/silcutil.[ch].
431 * Added support for specifying multiple public keys for Client
432 connection section in server configuration file. This makes it
433 possible to accept multiple public keys from same host, or to
434 make a section that accepts any incoming host, and have the
435 accepted public keys listed in the section.
437 Added functions silc_sever_[find/get]_public_key, added the
438 support for this actually to all connection sections but only
439 the Client section is currently allowed to specify multiple
442 Affected files are silcd/server.c, server_internal.h,
443 command.c, protocol.c, server_util.[ch], packet_receive.c.
445 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
447 * Merged Irssi 0.8.2 from irssi.org CVS.
449 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
451 * If silc_debug is TRUE, also output standard logging messages
452 to stderr with the debug output.
454 Made silc_log_reset_all() flushing all channels before returning.
455 Also fixed some documentation typos.
457 Affected files are lib/silcutil/silclog.[ch].
459 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
461 * Fixed the server to check correctly the amount of connections
462 from single host, by checking also the type of the connection.
463 Fixed also the comparison of number of connections and number
464 of allowed connections. Affected files are silcd/server.c,
467 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
469 * Fixed the USERS command reply to save the user's mode on the
470 channel as well. Fixed JOIN command reply to check whether a
471 client is on channel already and not join it twice. Affected
472 file lib/silcclient/command_reply.c.
474 * Added new file silc-expandos.c into irssi/silc/core/ to return
475 various stuff for various signal for the statusbar etc. updating.
476 Now Irssi SILC client prints channel user modes etc. on the
479 * The user mode (like server/router operator changes) is now shown
480 on the Irssi SILC client's statusbar. The affected files are
481 irssi/src/silc/core/client_ops.c, silc-expandos.c.
483 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
485 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
486 to SILC_SCHEDULE_[UN]LOCK macros.
488 * Added more error printing to logs in server code. Affected
489 files silcd/server.c and silcd/protocol.c.
491 * Fixed -S option parsing in Irssi SILC Client. Affected file
492 irssi/src/silc/core/silc-core.c.
494 * Added silc_buffer_alloc_size function. Affected file is
495 lib/silcutil/silcbuffer.h.
497 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
499 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
500 constants. Affected files in
501 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
504 * Changed the internal SFTP Memory FS table to const. Affected
505 file lib/silcsftp/sftp_fs_memory.c.
507 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
509 * Fixed the buffer formatting and unformatting routines to
510 check the size of 64 bits types with sizeof(). Affected
511 file is lib/silcutil/silcbuffmt.c.
513 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
515 * Removed 0.6.x backwards support.
517 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * Changed all integer type names:
520 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
521 to avoid collisions with other libraries using same type names
524 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Added `prefer_ipv6' argument to the functions
527 silc_net_gethostbyname[_async]. If it is TRUE it will return
528 IPv6 address over IPv4. If FALSE IPv4 address is returned
529 even if IPv6 address was found. Affected files
530 lib/silcutil/silcnet.[ch].
532 * Added support silc_net_create_connection[_async] to fallback
533 to IPv4 address if IPv6 address could not be used (like if

546 application does not need to define them. Affected file
547 includes/silcincludes.h.
549 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
550 old name went against naming convention. Applications now
551 include "silcclient.h" instead of "clientlibincludes.h".
552 Removed includes/clientlibincludes.h, it is redundant now.
554 * Renamed includes/version.h to silcversion.h.
556 * Added really preliminary support for OS/2 into the util
557 library. Only thread & mutex API is implemented, others
558 are still to be implemented. Created the lib/silcutil/os2/
559 directory. Created also file includes/silcos2.h.
561 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

590 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Added `user_count' to the SilcChannelEntry which now tells the
593 number of users on the channel. The user count is now saved
594 in normal server of global channels as well. Affected files
595 silcd/server.c, idlist.h, packet_receive.c and command.c.
597 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

609 Affected file lib/silcclient/client.c.
611 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
613 * ROBOdoc documented the lib/silcske/silcske.h, and improved
614 the SKE interface a bit.
616 * Fixed padding problem in PKCS#1. The padding was not actually
617 random since the random number generator was used incorrectly.
618 This security bug affects only when encrypting with PKCS#1, and
619 it is not currently used at all in SILC. SILC only use signing
620 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
622 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

639 Optimized the use of SKE Mutual flag usage. Use it only
640 if connection authentication protocol is not based in public
643 Renamed all SilcServerConfigSection* to SilcServerConfig*
644 to have a bit shorter names.
646 Affected files silcd/serverconfig.[ch], server.[ch], and
649 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

684 irssi/src/fe-text/silc.c.
686 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
688 * Added new configuration options and blocks:
689 keepalive_secs, reconnect_count, reconnect_interval,
690 reconnect_interval_max, reconnect_keep_trying and
691 require_reverser_lookup. Added ConnectionParam block, and
692 implemented the connection parameters when connecting as
693 initiator and when accepting connections as responder.

696 whether given configuration value has been given already.
698 Affected files silcd/serverconfig.[c], server.[c].
700 * Splitted the doc/example_silcd.conf.in. Separated the crypto
701 algorithm parts and created new file silcalgs.conf, that
702 is now included from the example_silcd.conf.in.
704 * Optimized the silc_server_connect_to_router_second to take
705 the connection configuration object from the SilcServerConnection
706 object instead of finding it during the connecting phase.
707 Added the configuration object to SilcServerConnection struct.
708 Affected files silcd/server_internal.h, server.c.
710 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

731 config file, allowing both public key and passphrase based
732 authentication to be set at the same time.
734 Added `prefer_passphrase_auth' setting in config file which
735 can be used to set to prefer passwd auth if both passwd and
736 public key is set. If not set, public key is preferred.
737 This has effect only when being initiator (responder will try
740 Added support for authentication with passphrase and public key
741 at the same time. The passphrase is tried first always since
742 it is faster to check.
744 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
746 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

785 correct client. Affected file lib/silcclient/client_notify.c.
787 * Make silc_rng_alloc fail if it cannot allocate the sha1
788 hash algorithm. Affected file lib/silccrypt/silcrng.c.
790 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
792 * Fixed the file transfer's key agreement payload to include
793 zero port also if the hostname is NULL because it could not
796 Call file transfer monitor callback now also if error occurs
797 during key agreement protocol.
799 Changed the silc_client_file_send interface to return the
800 SilcClientFileError instead of session id. The session ID
801 is returned into pointer provided as argument.
803 Check that the file exists locally before sending the
804 file transfer request at all.
806 Affected file lib/silcclient/client_ftp.c, silcapi.h.

817 SILC_LOG_WARNING to give out Warning and not Error. Affected
818 file lib/silcutil/silclog.c.
820 * Fixed the channel message payload decryption in the function
821 silc_channel_message_payload_decrypt to not modify the original
822 buffer before it is verified that the message decrypted
823 correctly. Otherwise, next time it is called with correct
824 channel key it won't encrypt since the payload is corrupted.
825 Affected file lib/silccore/silcchannel.c.
827 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

864 silc_client_replace_channel_id, and removed functions
865 silc_client_new_channel_id and silc_idlist_get_channel_by_id
868 * Added cross reference of the joined channels to the
869 SilcClientEntry, and changed the SilcChannelEntry's
870 users list to SilcHashTable. The affected files are
871 lib/silcclient/idlist.[ch].
873 * Fixed a bug in hash table tarversing. While the hash table
874 is traversed with SilcHashTableList the table must not be
875 rehashed. It is now guaranteed that auto rehashable tables
876 are not rehashed while tarversing the list. Also defined that
877 silc_hash_table_rehash must not be called while tarversing
878 the table. Added function silc_hash_table_list_reset that must
879 be called after the tarversing is over. The affected files are
880 lib/silcutil/silchashtable.[ch].
882 * Changed all hash table traversing to call the new
883 silc_hash_table_list_reset in server and in client library.
885 * Added function silc_client_on_channel to return the
886 SilcChannelUser entry if the specified client entry is joined
887 on the specified channel. This is exported to application as
888 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
890 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

893 server. The notify for mode change must be sent always and
894 not only if !cmd->pending. Affected file silcd/command.c.
896 * Fixed the WHOWAS command's reply sending to support the
897 lists correctly. Affected file silcd/command.c.
899 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * When sending JOIN command to router for processing the
902 sender's old command identifier was not saved back to the
903 sender's command context, fixed now. The affected file is
906 * Create the key in JOIN command of the router did not return
907 the channel key, added check for this. Affected file is
910 * Fixed a channel ID update bug in JOIN command reply. Do
911 not directly upgrade the ID but call the function
912 silc_idlist_replace_channel_id if the ID was changed.
913 Affected file silcd/command_reply.c.
915 * Fixed memory leaks from command calling if it would fail.
916 Affected file silcd/command.c.

928 * Removed TRQ from lib/trq, not needed anymore.
930 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
931 with server connections. Later this will be configurable
932 in config file after new config file is done. Affected file
935 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
937 * Fixed a crash in server related to channel announcements.
938 Affected file silcd/server.c.
940 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
942 * Fixed memory leaks in silc_server_create_new_channel*
943 functions. Affected file silcd/server.c.
945 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
946 which ID was changed. This way the router will send the
947 user list for the channel again, and server won't be in
948 desync in some rare circumstances. Affected file is
949 silcd/packet_receive.c.
951 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

980 file silcd/packet_receive.c and silcd/command.c.
982 * Fixed the SERVER_SIGNOFF notify handling on normal server
983 not to save the history information for clients. Same was
984 fixed earlier in remove_clients_by_server function, but not
985 here. Affected file silcd/packet_receive.c.
987 * Raised the default connection-retry count from 4 to 7 in
988 server. Affected file silcd/server.h.
990 * Cancel any possible reconnect timeouts when we start the

998 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1000 * Fixed the NICK command to always give the unformatted
1001 nickname to the one giving the NICK command. If unformatted
1002 nickname is cached already it will be formatted and the
1003 local entry will always get the unformatted nickname.
1004 Affected file lib/silcclient/idlist.c.
1006 * Fixed some double frees from client library commands.
1007 Affected file is lib/silcclient/command.c.
1009 * Fixed CUMODE command in server to assure that no one can

1011 little bug. Affected file silcd/command.c.
1013 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1015 * Removed the SilcClientCommandDestructor from the client
1016 libary, it is not needed anymore. Affected files are
1017 lib/silcclient/silcapi.h, command[_reply].[ch],
1018 client_notify, idlist.c.
1020 * Fixed GETKEY command to first resolve client, and then
1021 resolve the server only if the client was not found, instead
1022 of resolving both at the same time. Affected file is
1023 lib/silcclient/command.c.
1025 * Added silc_client_start_key_exchange_cb and lookup the
1026 remote hostname and IP address before starting the key
1027 exchange with server. The affected file is
1028 lib/silcclient/client.c.
1030 * The server's public key is now saved using the IP address
1031 of the server and not the servername for the filename.
1032 The hostname public key filename is checked as an fall back
1033 method if the IP address based filename is not found.
1035 Fixed the GETKEY command to save the fetched server key
1036 in correct filename.
1038 Print the remote server's hostname now when new key is
1039 received during connection process. Affected file is
1040 irssi/src/silc/core/client_ops.c.
1042 * Return always our own public key to the client if it asks
1043 for it with GETKEY command. Affected file silcd/command.c.
1045 * Removed the use_auto_addr variable from default config
1046 file since it was in wrong section. Affected file is
1049 * Fixed TOPIC_CHANGE notification to not route it when it
1050 was sent using silc_server_send_notify_to_channel function.
1051 Affected file silcd/command.c.
1053 * Fixed silc_server_send_notify_kicked to send the kicker's
1054 Client ID also, it was missing. Affected files are
1055 silcd/command.c, silcd/packet_send.[ch].
1057 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1059 * Do not save client history information in SERVER_SIGNOFF.
1060 Fixes the bug in normal server that it does not detect
1061 the client becoming valid after the server becomes back
1062 online. Affected file silcd/server_util.c.
1064 * Added `sock_error' field into the SilcSocketConnection
1065 context. When error occurs during socket operation (read
1066 or write) the error is saved. Added also new function
1067 silc_socket_get_error to return human readable socket error
1068 message. Affected files are lib/silcutil/silcsockconn.[ch],
1069 lib/silcutil/unix/silcunixsockconn.c, and
1070 lib/silcutil/win32/silcwin32sockconn.c.
1072 * The server now prints the socket error message in the
1073 signoff for client. Affected file silcd/server.c.
1075 * Fixed the `created' channel information sending from router
1076 to server in JOIN command. Checks now whether the channel
1077 really was created or not and set it according that.
1079 Fixed the JOIN command to use the client entry's current
1080 ID during the joining procedure instead of the one it sent
1081 in the command (it is checked though), since it can change
1082 between the packet processing and command processing, and
1083 would just case unnecessary pain in the client end. Affected
1084 file silcd/command.c.
1086 * Fixed a channel key payload sending to use correct channel
1087 ID when the server was forced to change the channel's ID by
1088 router. Router sent the key payload with the old Channel ID.
1089 Affected file silcd/packet_receive.c.
1091 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1093 * Call silc_server_save_channel_key only if the key payload
1094 was provided in the JOIN command's command reply. Affected
1095 file silcd/command_reply.c.
1097 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1099 * Fixed silc_mp_sizeinbase to return the value correctly with
1100 MPI. Affected file lib/silcmath/mp_mpi.c.
1102 * Fixed the stop_server signal to correctly stop the scheduler
1103 and gracefully stop the server when SIGTERM or SIGINT signals
1104 are received. Affected file silcd/silcd.c.
1106 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1108 * Simple handling of TERM and HUP signals. Also added some log
1109 flushing call around. Affected file is
1112 * Fixed small bugs in silclog.c. Now buffering output will take
1113 effect after 10 seconds since startup: This will ensure that
1114 no important startup messages are lost. Also output redirection
1115 will preserve original format ([Date] [Type] message).
1116 Affected file is lib/silcutil/silclog.c.
1118 * Added two options to the config file, in the logging section:
1119 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1120 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1122 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1124 * Do not print the warning about log files not being initialized
1125 more than once to avoid excess logging. Affected file is
1126 lib/silcutil/silclog.c.
1128 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1129 the SIM copying in make install in Makefile.am.pre.
1131 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1133 * Rewritten silclog APIs. Globally interesting changes follows:
1134 silc_log_set_files() changed to silc_log_set_file().
1135 silc_log_set_callbacks() changed to silc_log_set_callback().
1136 ROBOdoc documented silclog header file.
1137 SilcLogCb now returns bool to wether inihibit the default
1138 handler or not (to keep the old behaviour return always TRUE).
1139 The new APIs should also fix the problem of the
1140 silcd_error.log file that was written in the current directory.
1143 Log files streams will remain opened after silc_log_set_file()
1144 call, means less CPU usage notably on high traffic servers.
1145 File streams are now full buffered, and flushed to the disk
1146 every 5 minutes, lesses HD activity and CPU usage.
1147 Messages can be redirected, allowing admins to configure
1148 one single logfile for all server messages.
1149 the silc_log_quick global variable to activate fast-logging.
1150 Affected files lib/silcutil/silclog.[ch]
1152 * Changed some code to conform new silclog APIs. Affected
1153 files are doc/example_silcd.conf.in, silcd/server.c
1154 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1157 * Fixed a memory leak that could occur in some situations.
1158 Affected file silcd/serverconfig.c.
1160 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Added the silc_client_del_client to remove the client from
1163 all channels as well. Affected file lib/silcclient/idlist.c.
1165 * Fixed the client library to correctly remove the client
1166 from all channels when the client entry is being destroyed.
1167 Affected file lib/silcclient/client_notify.c, command.c.
1169 * Added auto-nicking support to the client library. If the
1170 applicatio now sets client->nickname it will be sent to the
1171 server after connecting by the library. This way for example
1172 SILCNICK (or IRCNICK) environment variables will have effect
1173 and always change the nickname automatically to whatever
1174 it is wanted. Affected file lib/silcclient/client.[ch].
1176 * Renamed silc_server_command_bad_chars to the
1177 silc_server_name_bad_chars and moved it to the
1178 silcd/server_util.[ch]. Added also new function
1179 silc_server_name_modify_bad to return nickname that
1180 includes bad characters as new nickname without those
1181 bad characters. This check and modify is now used in
1182 silc_server_new_client when the username is initially set
1183 as nickname, so it must be checked to be valid nickname.
1184 Affected file silcd/packet_receive.c.
1186 * The nickname length is now taken from the packet for real
1187 and not trusted to strlen() since it clearly can return
1188 wrong length for nickname including bad characters. This
1189 also applies to channel names. Affected file silcd/command.c.
1191 * Removed the lib/silcsilm/modules directory. Modules are now
1192 compiled into the lib/silcsim. Fixed the copying of the
1193 modules to follow symbolic links in Makefile.am.pre.
1195 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Fixed silc_string_regexify list creation. Fixes bugs with
1198 BAN and INVITE commands in server. The affected file is
1199 lib/silcutil/unix/silcunixutil.c.
1201 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Removed the command destructor entirely from the server's
1204 command and command reply routines. It is not needed, and
1205 its usage was buggy and caused crashes. Affected files are
1206 silcd/command[_reply].[ch].
1208 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Cancel protocol and NULL sock->protocol if timeout
1211 occurred during protocol. Affected file silcd/server.c.
1213 * Cancel protocol timeouts always before calling the final
1214 callback, to assure that after final callback is called
1215 no other state will be called for the protocol anymore.
1216 Affected file silcd/protocol.c.
1218 * Print error log if incoming connection configuration could
1219 not be found. Affected file silcd/server.c.
1221 * Fixed JOIN command to correctly save the founder mode
1222 to the client on normal SILC server, when the channel
1223 was created by the router. Affected file silcd/command.c.
1225 * Fixed LIST command (hopefully) to send correct reply
1226 packets. Affected file silcd/command.c.
1228 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * The silc_packet_receive_process now returns FALSE if the
1231 read data was invalid packet, and TRUE if it was ok.
1233 The server now checks that if unauthenticated connection
1234 sends data and its processing fails the server will close
1235 the connection since it could be a malicious flooder.
1237 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1239 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1241 * Make sure the warning about error opening a log file is
1242 printed only once and not everytime it fails (produces
1243 too much useless log). Affected file lib/silcutil/silclog.c.
1245 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1247 * Made the silc_server_daemonise() function more readable.
1248 Affected file silcd/server.c.
1250 * Pid file is now optional, the user may comment it out from
1251 the config file. Removed define SILC_SERVER_PID_FILE, we
1252 don't need a default any longer. Affected file
1253 configure.in.pre, lib/Makefile.am.pre.
1255 * Make some use of the pid file. The server now dies at startup
1256 if it detects a valid pid file on his path. The server would
1257 die anyway in this circumstance, because of the bind() failure.
1258 Affected file silcd/silcd.c.
1260 * No longer compiling lib/dotconf.
1262 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1264 * Fixed JOIN command parsing not to crash. Affected file
1265 lib/silcclient/command.c.
1267 * Fied the NICK_CHANGE notify to add the new client entry
1268 even it is resolved. This removes an <[unknown]> nick
1269 thingy bug in the client. Affected file is
1270 lib/silcclient/client_notify.c.
1272 * Do not try to allocate 0 bytes (efence does not like it)
1273 in lib/silccore/silccomand.c when encoding payload.
1275 * Do not take IRCNICK as nickname in Irssi SILC client since
1276 it is not possible to set nickname before hand connecting
1277 the server (TODO has an entry about adding auto-nicking
1280 * Changed the silc_server_command_pending to check whether
1281 there already exists an pending entry with the specified
1282 command, command identifier and pending callback. This is
1283 to fix IDENTIFY and WHOIS related crashes that may register
1284 multiple pending commands with same identifier. Affected
1285 file silcd/command.c.
1287 * Fixed the server to reconnect to the router even if it
1288 was already reconnecting and EOF was received. This to
1289 fix a possibility that the server wouldn't ever try to
1290 auto-reconnect to the router. Affected file silcd/server.c.
1292 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1294 * Fixed the server's password authentication to use the
1295 length of the locally saved password, and not the one
1296 sent in the packet. Affected file silcd/protocol.c.
1298 * Fixed same password authentication problem in the
1299 Authentication Payload handling routines in
1300 lib/silccore/silcauth.c.
1302 * Yet another password authentication problem fixed with
1303 channel password handling in silcd/command.c.
1305 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * If first character of string in silc_parse_userfqdn is '@'
1308 then do not parse it. Affected file is
1309 lib/silcutil/silcutil.c.
1311 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Fixed minor bug in IDENTIFY command reply sending, which
1314 caused various weird problems during JOIN when it was
1315 resolving names for users. Affected file silcd/command.c.
1317 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Fixed the IDENTIFY command reply sending to chech better valid
1320 clients. It was possible to send incomplete list of replies.
1321 Affected file silcd/command.c.
1323 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Added silc_client_command[s]_[un]register functions now to
1326 dynamically register the commands in client library. Removed
1327 the static table of commands. This allows the client library
1328 to call commands without causing the application to know about
1329 what commands library has called.
1331 Removed the INFO command reply kludge to detect when the command
1332 was called by library. Now library use its own command reply
1333 function for INFO command.
1335 Added function silc_client_command_call to call a command.
1336 Application can use it to call command, not access the structure
1339 Now all commands that are sent by the client library (not
1340 explicitly sent by application) use own command reply functions.
1342 Affected files around lib/silcclient/ and in
1343 irssi/src/silc/core/.
1345 * Fixed the WHOIS command reply sending to chech better valid
1346 clients. It was possible to send incomplete list of replies.
1348 Fixed the WHOIS and IDENTIFY to send the request to router
1349 if normal server did not do it and did not find any results.
1351 Affected file silcd/command.c.
1353 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1355 * Moved the internal data from SilcClient context into its
1356 own file, not accesible to application. Affected files
1357 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1358 and other files in client library.
1360 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Added doc/examples installation target in Makefile.am.pre.
1365 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1367 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1368 commands the found client entry will be removed from the
1369 cache, after notifying application about the error. Affected
1370 file lib/silcclient/command_reply.c.
1372 * Changed the /MSG to check for exact nickname user gave, and
1373 not let `nick' match `nick@host' if it is only one found. Now,
1374 user must type the exact nickname (like nick@host2) even if
1375 there are no more than one same nicks found. This is to avoid
1376 a possibility of sending nickname to wrong nickname since
1377 `nick' could match `nick@host'. Affected file is
1378 irssi/src/core/silc-servers.c.
1380 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1382 * Do not print "you are now server operator" or similar when
1383 giving /away command. Affected files are
1384 irssi/src/silc/core/client_ops.c, silc-servers.h.
1386 * Made the silc_server_command_pending_error_check to send
1387 the same command reply payload it received back to the
1388 original sender of the command. This way all arguments
1389 that was received by the server will be received by the
1390 client too. Affected file silcd/command.c.
1392 * Added the silc_idcache_add to return the created cache entry
1393 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1395 * Add global clients to expire if they are not on any channel.
1396 This is because normal server will never know if they signoff
1397 if they are not on any channel. The cache expiry will take
1398 case of these entries. This is done by normal servers only.
1399 The affected files are silcd/command_reply.c,
1400 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1402 * If server receives invalid ID notification for WHOIS or
1403 IDENTIFY and the ID exists in the lists, it is removed.
1404 Affected file silcd/command_reply.c.
1406 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1407 in client then client entry that it matches is searched and
1408 the nickname is printed on the screen for user. Affected
1409 file irssi/src/silc/core/client_ops.c.
1411 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Use cache entry expire time in the LIST command reply to
1414 purge old entries from the cache after the LIST command
1415 reply has been received. This way we don't have non-existent
1416 entries in the cache for too long. Affected file is
1417 silcd/command_reply.c.
1419 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * If we are normal server, and we've not resolved client info
1422 in WHOIS or IDENTIFY from router, and it is global client,
1423 we'll check whether it is on some channel. If it is not
1424 then we cannot be sure about its validity and will resolve it
1425 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1426 file silcd/command.c.
1428 * Search channel by name (if possible) rather than by ID
1429 in IDENTIFY command's command reply. Affected file is
1430 silcd/command_reply.c.
1432 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1435 Updated specs and implemented it. Affected file silcd/command.c,
1436 silcd/packet_send.c and silcd/packet_receive.c.
1438 * Implemented the <founder auth> payload handling in the JOIN
1439 command. If provided all conditions for channel joining
1440 except requirement to provide correct passphrase can be
1441 overrided by the channel founder. Updated the protocol specs.
1442 Affected file silcd/command.c.
1444 Added support for founder auth in JOIN command in client
1445 library. Fixed the parsing of the JOIN command now to support
1446 all options as they should be. The affected file is
1447 lib/silcclient/command.c.
1449 * Optimized the WHOIS and IDENTIFY commands to send the request
1450 to router only if it includes nicknames or other names. If
1451 they include only IDs then check the local cache first before
1452 routing. Affected file is silcd/command.c.
1454 * Added channels topic announcements. Affected file is
1455 silcd/packet_receive.c and silcd/server.c.
1457 * Fixed the silc_server_send_notify_topic_set to really destine
1458 the packet to channel. Affected file silcd/packet_send.c.
1460 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1461 library. Affected file lib/silcclient/client_notify.c.
1463 * Added UMODE announcements. Affected file silcd/server.c.
1465 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Memory leak fixes in:
1469 lib/silcutil/silcsockconn.c
1470 lib/silcske/silcske.c
1471 lib/silcske/groups.c
1473 lib/silccrypt/silcpkcs.c
1474 lib/silccore/silccommand.c
1475 lib/silccore/silcidcache.c
1480 * ROBOdoc documented the lib/silcske/groups.h file and a
1481 bit changed the interface for better.
1483 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1485 * Update the client entry context in the ID cache after
1486 nick change. Affected file lib/silcclient/command.c.
1487 Fixes the CUMODE command when regaining founder privileges,
1488 and a little WHOIS problem.
1490 * Fixed silc_net_gethostbyname to correctly call the
1491 inet_ntop. Affected file lib/silcutil/silcnet.c.
1493 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1495 * Added IPv6 support checking to the configure.in.pre, added
1496 also --enable-ipv6 option to override the check. Affected
1497 file configure.in.pre.
1499 * The silc_thread_create now calls the start function
1500 directly if threads support is not compiled in. Removes
1501 ugly #ifdef's from generic code. Affected files are
1502 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1504 * Added silc_net_gethostby[name/addr]_async to asynchronously
1505 resolve. Affected files are lib/silcutil/silcnet.[ch].
1507 * Added support for rendering IPv6 based server, client and
1508 channel IDs. Affected file lib/silcutil/silcutil.c.
1510 * Added support for creating IPv6 based server IDs. Affected
1511 file is silcd/serverid.c.
1513 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1515 * Added silc_net_gethostby[addr/name] into the
1516 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1517 routines. Added silc_net_is_ip[4/6]. Affected file is
1518 lib/silcutil/unix/silcunixnet.c. All routines that take
1519 address as argument now supports both IPv4 and IPv6 addresses.
1521 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1523 * Fixed LIST command reply sending in server. Affected file
1526 * Server now sends the kicker's client ID in the KICK notify
1527 to the kicked client. Affected file silcd/command.c.
1529 * The client library now parses the kickers client ID and
1530 UI displays it. Affected files lib/silcclient/client_notify.c
1531 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1533 * Made all payload parsing function prototypes consistent.
1534 They all take now const unsigned char * and uint32 pair as
1535 the payload data instead of SilcBuffer. Changes all around
1536 the source tree. Other unsigned char* -> const unsigned char*
1537 changes around the tree as well.
1539 * Optimized SFTP client and server packet sending not to
1540 allocate new buffer for each packet but to recycle the
1541 first allocated buffer. Affected files are
1542 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1544 * Optimized the SFTP client to use SilcList instead of
1545 SilcDList for requests, because it is faster. Affected file
1546 is lib/silcsftp/sftp_client.c.
1548 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1549 into lib/silccore/silcid.[ch].
1551 Renamed silcpayload.[ch] into silcargument.[ch].
1553 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * If client entry is deleted with active key agreement
1556 session, abort the session.
1558 The silc_client_abort_key_agreement now calls the completion
1559 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1561 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1564 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Don't use __restrict in older GCC's. Affected file is
1567 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1569 * silc_net_localhost now attempts to reverse lookup the
1570 IP/hostname. Affected file lib/silcutil/silcnet.c.
1572 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1573 command. It can be used to gain founder privileges at
1574 the same time when joining the channel.
1576 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1577 kicker's client ID as well. Updated protocol specs.
1579 Defined that the server must send SILC_COMMAND_IDENTIFY
1580 command reply with error status to client who sent
1581 private message with invalid client ID.
1583 Updated the protocol specification.
1585 * Added silc_server_send_command_reply to send any
1586 command reply. Affected file silcd/packet_send.[ch].
1588 * Added silc_id_payload_encode_data to encode ID payload
1589 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1591 * The server now send IDENTIFY command reply with error
1592 status if client ID in private message is invalid. Affected
1593 file silcd/packet_receive.c.
1595 * Save the server key file with server's IP address in
1596 the filename instead of hostname. The affected file is
1597 irssi/src/silc/core/client_ops.c.
1599 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1604 * Added libtool support for compiling shared objects in
1605 lib/silcsim. Affected file configure.in.pre and
1606 lib/silcsim/Makefile.am. Original patch by cras.
1608 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Pid file configuration, and server's config file fixes
1611 patch by toma. Updated CREDITS file.
1613 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Fixed silc_client_channel_message to not try to decrypt
1616 the message twice if it resolved the destination client
1617 information. This could cause of dropping one channel
1618 message. Affected file lib/silcclient/client_channel.c.
1620 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1623 lib/silcclient/client.c. This function is used when the SILC
1624 Client is run under some other scheduler, or event loop or
1625 main loop. On GUI applications, for example this may be
1626 desired to used to run the client under the GUI application's
1627 main loop. Typically the GUI application would register an
1628 idle task that calls this function multiple times in a second
1629 to quickly process the SILC specific data.
1631 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1633 * Fixed silc_server_drop() for dropping the supplementary
1634 groups as well, this could cause a security hole on some
1637 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1642 * Write PID file after dropping privileges. Added -F option
1643 to run server on foreground. A patch by debolaz.
1644 Affected files silcd/server.c, silcd/silcd.c.
1646 * Fixed MOTD to return the MOTD file server name. Affected
1647 file silcd/command.c.
1649 * Added INFO command reply handling to the Irssi SILC Client.
1650 Affected file irssi/src/silc/core/client_ops.c.
1652 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Fixed the silc_idcache_list_* routines to really support
1655 the dynamic list. Fixes a crash. Affected file is
1656 lib/silccore/silcidcache.c.
1658 * Fixed the LIST command reply to really call LIST command's
1659 pending callbacks. Affected file silcd/command_reply.c.
1661 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Update conn->local_entry->nickname after giving NICK
1664 command. Affected file lib/silcclient/command.c.
1666 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1668 * Added the [pid] option to the silcd configuration file
1670 Affected files: serverconfig.[ch] and silcd.c
1672 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Save fingerprint in WHOIS command reply in server.
1675 Affected file silcd/command_reply.c.
1677 * Fixed NICK commands pending callback registration.
1678 Affected file lib/silcclient/command.c.
1680 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Use ++server->cmd_ident when sending commands in server,
1683 instead of random number. Affected file silcd/command.c.
1685 * Fixed GETKEY command reply to call actually GETKEY pending
1686 command callbacks. Affected file silcd/command_reply.c.
1688 * A bit stricter check for nicknames. Check for same nickname
1689 in NICK command also. Affected file silcd/command.c.
1691 * Do not call INFO command everytime client ID changes, only
1692 during first connecting. Affected file lib/silcclient/client.c.
1694 * Set the new nickname only after successful command reply for
1695 NICK command is returned by server. Affected file
1696 lib/silcclient/command.c.
1698 * Remove nicknames from nicklist during server_signoff notify.
1699 Should fix /NAMES bit more. The affected file is
1700 irssi/src/silc/core/silc-channels.c.
1702 * Added `fingerprint' field to the SilcIDListData in the
1703 silcd/idlist.h to hold the fingerprint of the client's
1706 Send the fingerprint of the client's public key in WHOIS
1709 Affected files silcd/command.c, and silcd/idlist.[ch].
1711 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1712 create fingerprint from given data.
1714 * Show the fingerprint of the client's public key in WHOIS.
1715 Affected files irssi/src/module-formats.[ch] and
1716 irssi/src/silc/core/client_ops.c.
1718 * Format the multiple same nicknames also during JOIN and
1719 NICK_CHANGE notifys. Affected file is
1720 lib/silcclient/client_notify.c.
1722 * Do not print error on screen for invalid private message
1723 payload since it can come if someone is sending private
1724 messages with wrong key. Affected file
1725 lib/silccore/silcprivate.c.
1727 * Fixed multiple concurrent /PING crash. Affected file
1728 lib/silcclient/command.c.
1730 * Changed the wrong ID encoding. All IP addresses must be
1731 in MSB first order in encoded format. They were encoded
1732 wrong and was in LSB format. Affected files are
1733 silcd/serverid.c, lib/silcutil/silcutil.c.
1735 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1737 * Call the `connect' client operation through the scheduler
1738 in case of error. Affected file lib/silcclient/client.c.
1740 * Call the `failure' client operation even if the error
1741 occurred locally during a protocol. Affected file is
1742 lib/silcclient/protocol.c.
1744 * Added support of sending LIST command to router from normal
1745 server. This way normal server can get list of all channels
1746 in the network too. Fixed the channel list sending in the
1747 server too. Affected files are silcd/command.c, and
1748 silcd/command_reply.[ch].
1750 * Added silc_server_update_channels_by_server and
1751 silc_server_remove_channels_by_server. They are used during
1752 disconnection of primary router and in backup router protocol.
1753 Affected file silcd/server_util.[ch], silcd/server.c and
1754 silcd/server_backup.c.
1756 * Fixed channel adding to global list in IDENTIFY command
1757 reply in server. Affected file silcd/command_reply.c.
1759 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * If the incoming packet type is REKEY or REKEY_DONE process
1762 that packet always synchronously. Fixes yet another MAC
1763 failed error on slow (dialup) connections. Affected file
1764 lib/silcclient/client.c and silcd/server.c.
1766 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1768 * Call check_version SKE callback for initiator too. Affected
1769 file lib/silcske/silcske.c.
1771 * Implemented fix for security hole found in the SKE that was
1772 fixed in the specification few days back; the initiator's
1773 public key is now added to the HASH value computation.
1774 Added backwards support for the old way of doing it too, for
1775 old clients and old servers. Affected file is
1776 lib/silcske/silcske.c.
1778 * Enabled mutual authentication by default in SKE. If initiator
1779 is not providing mutual authentication the responder will
1780 force it. This will provide the proof of posession of the
1781 private key for responder. The affected files are
1782 lib/silcclient/protocol.c and silcd/protocol.c.
1784 * Do not cache anymore the server's public key during SKE.
1785 We do mutual authentication so the proof of posession of
1786 private key is done, and if the server is authenticated in
1787 conn auth protocol with public key we must have the public
1788 key already. Affected file silcd/protocol.c.
1790 * Added new global debug variable: silc_debug_hexdump. If
1791 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1792 file lib/silcutil/silclog.[ch].
1794 * Fixed compilation warning due to char * -> const char *.
1795 Affected files lib/silcutil/silcnet.h, and
1796 lib/silccore/silcauth.[ch].
1798 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1800 * Fixed CMODE command when new channel key was created. If
1801 the creation failed the old key was removed. Next time giving
1802 same command would crash the server since the old key was
1803 freed already. Affected file silcd/command.c.
1805 * Fixed the silc_server_announce_get_channels to not crash
1806 on reconnect. Affected file silcd/server.c.
1808 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Added silc_log_set_debug_string function to set a regex
1811 string to match for debug output. Only the function names,
1812 or filenames matching the given debug string is actually
1813 printed. This way it is possible to filter out those debug
1814 strings that user is not interested in.
1816 Fixed a bug in silc_string_regexify.
1818 Affected files lib/silcutil/silclog.[ch], and
1819 lib/silcutil/unix/silcunixutil.c.
1821 * Changed the -d options in both server and Irssi SILC client
1822 to take the debug string as argument. Affected files
1823 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1825 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1827 * Added silc_hash_babbleprint to create a Bubble Babble
1828 Encoded fingerprint. The encoding is developed by Antti
1829 Huima (draft-huima-babble-01.txt), and it creates human
1830 readable strings out of binary data. Affected file
1831 lib/silccrypt/silchash.[ch].
1833 * Print the babble print now in addition of fingerprint as well
1834 in Irssi SILC client. Affected files are
1835 irssi/src/fe-common/silc/module-formats.[ch],
1836 irssi/src/fe-common/silc/core/client_ops.c.
1838 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Fixed a security problem found in SKE. The initiator's
1841 public key too is now added to the HASH hash value creation
1842 which is signed by the responder to create the SIGN value.
1843 This will prevent anyone in the middle to lie to the responder
1844 about the initiator's public key. If this is done now, the
1845 man in the middle will get caught. Updated the protocol
1848 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Better installation directory handling. Configure module
1851 paths and other paths automatically to example_silc* files
1852 in doc/. A patch by toma.
1854 * Fixed compiler warning from MPI library, and from SILC RNG.
1857 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1858 It can be configured with ./configure. A patch by toma.
1860 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Find correct make to use in prepare-clean. A patch by
1863 toma. Affected file prepare-clean.
1865 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1867 * Added irssi variables use_auto_addr, auto_bind_ip,
1868 auto_bind_port and auto_public_ip.
1870 * Changed the interface for silc_client_send_key_agreement
1871 in lib/silcclient/silcapi.h
1875 irssi/src/silc/core/silc-core.c
1877 lib/silcclient/silcapi.h
1878 irssi/src/silc/core/silc-channels.c
1879 lib/silcclient/client_keyagr.c
1882 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Added silc_pkcs_public_key_compare to compare two
1885 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1887 * Check that the client who set the founder mode on the
1888 channel is the same client that is giving the founder
1889 mode to itself. It is done by comparing the saved public
1890 key (it is saved even in the authentication is passphrase).
1891 Affected file silcd/command.c.
1893 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Do not process packet for disconnected socket connection.
1896 Affected file lib/silccore/silcpacket.c.
1898 * Process the DISCONNECT packet through scheduler in the
1899 client library. Affected file lib/silcclient/client.c.
1901 * Fixed the silc_client_packet_parse to not to increase
1902 the packet sequence number if the conn->sock and the
1903 current socket connection is not same. This can happen
1904 for example during key agreement when the conn includes
1905 multiple socket connections (listeners). Affected file
1906 lib/silcclient/client.c.
1908 * The sender of the file transfer request now provides also
1909 the pointer (listener) for the key exchange protocol. If
1910 the listener cannot be created then it sends empty key
1911 agreement and lets the receiver provide the listener.
1913 Added `local_ip' and `local_port' arguments to the
1914 silc_client_file_send. If they are provided they are used,
1915 if not then it will attempt to find local IP address, if
1916 not found or bind fails then the remote client will provide
1919 Affected files are lib/silcclient/client_ftp.c and
1920 lib/silcclient/silcapi.h.
1922 * Extended the FILE SEND command to support defining the
1923 local IP and port for key exchange listener. They are
1924 optional. Affected file irssi/src/silc/core/silc-servers.c.
1926 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Defined to WHOIS command reply the sending of fingerprint
1929 of the client's public key (if the proof of posession of the
1930 corresponding private key is verified by the server).
1931 Updated to the protocol specification.
1933 * Added support of receiving the client's public key's
1934 fingerprint in command reply in client library. Affected
1935 file is lib/silcclient/command_reply.c, and
1936 lib/silcclient/idlist.[ch].
1938 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Do not send over 128 chars long nickname to the server
1941 in NICK command. Affected file lib/silcclient/command.c.
1943 * Do not send over 256 chars long channel names to the server
1944 in JOIN command. Affected file lib/silcclient/command.c.
1946 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Assure that silc_server_close_connection cannot be called
1949 twice for same socket context. Affected file is
1952 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Send error message to application if opening file for
1955 writing during file transfer fails. Affected file is
1956 lib/silcclient/client_ftp.c.
1958 Remove all file transfer sessions for a client that we're
1959 removing from ID cache.
1961 Affected file is lib/silcclient/client_ftp.c.
1963 * Fixed silc_net_addr2bin to return correct address. Affected
1964 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1966 * Fixed file transfer session removing on signoff notify.
1967 Affected file irssi/src/silc/core/silc-servers.c.
1969 * Added the SilcClientFileError to be returned in the monitor
1970 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1971 Affected file lib/silcclient/silcapi.h.
1973 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1975 * Fixed a crash in silc_client_ftp_free_sessions and
1976 silc_client_ftp_session_free_client. Affected file
1977 lib/silcclient/client_ftp.c.
1979 * Added `disabled' field in the SilcChannelEntry in the server
1980 to indicate if the server entry is disabled. Affected file
1981 silcd/idlist.h, silcd/command[_reply].c.
1983 * SILC server adds now /var/run/silcd.pid everytime it is
1984 started. Affected file silcd/silcd.c.
1986 * Added silc_server_packet_send_clients to send a packet to
1987 the provided table of client entries. Affected file
1988 silcd/packet_send.[ch].
1990 * Fixed a crash in client resolving in client_prvmsg.c in
1991 client library. Affected file lib/silcclient/client_prvmsg.c.
1993 * Do not actually remove the client directly from ID cache
1994 during SERVER_SIGNOFF, but invalidate it. This way we
1995 preserve the WHOWAS info for the client. Affected file
1996 silcd/server_util.c.
1998 * Fixed SERVER_SIGNOFF notify handling in the server. The
1999 server is now able to process incoming SERVER_SIGNOFF notify
2000 for a server that it doesn't even know about. It will remove
2001 the clients provided in the notify. Affected file
2002 silcd/packet_receive.c.
2004 * Check for partial packet in data queue after every packet that
2005 was found from the queue. Return and wait for more data if
2006 there is partial data in queue. Affected file is
2007 lib/silccore/silcpacket.c.
2009 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Added SilcClietFileError enum to indicate error in
2012 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2013 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2014 Affected files lib/silcclient/silcapi.h and
2015 lib/silcclient/client_ftp.c.
2017 * Check that newsize in silc_buffer_realloc is larger than
2018 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2020 * Added better monitor of file transfers. It now monitors
2021 key agreement protocol during the file transfer too. Added
2022 error reporting too. Affected files
2023 irssi/src/silc/core/silc-servers.c,
2024 irssi/src/fe-common/silc/module-formats.[ch].
2026 * Wrote a help file for FILE command.
2028 * Added silc_rng_global_get_byte_fast to get not-so-secure
2029 random data as fast as possible. Random data is read from
2030 /dev/urandom if available and from the SILC RNG if not
2031 available. It is used in padding generation. Affected file
2032 lib/silccrypt/silcrng.[ch].
2034 * All packets in client library are now processed synchronously.
2035 Optimized packet processing a lot. Affected file
2036 lib/silcclient/client.c.
2038 * All server connection packets are processing synchronously
2039 now in server, to optimize packet processing. Affected file
2042 * Include files are installed now only in Toolkit distribution
2043 if make install is given. Affected files: all Makefile.am's.
2045 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Assure that silc_client_notify_by_server_resolve does not
2048 resolve the client information multiple times. If it cannot
2049 be found by the first it cannot be found at all. Affected
2050 file lib/silcclient/client_notify.c.
2052 * Fixed WHOWAS command reply calling. Affected file
2053 lib/silcclient/command_reply.c.
2055 * Removed all references to silc_idlist_get_client from the
2056 Irssi SILC client since that call is internal call used by
2057 the library. The Irssi SILC client will use now client
2058 retrieval functions found in silcapi.h.
2060 * Fixed a bug in resolving nickname info before sending
2061 private message. It used freed memory. Affected file
2062 irssi/src/silc/core/silc-servers.c.
2064 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Assure my_channels statistics cannot go negative in server.
2067 Affected files silcd/server.c, silcd/server_util.c.
2069 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2081 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Added silc_net_localip to return local host's IP address.
2084 Affected file lib/silcutil/silcnet.[ch].
2086 * If key exchange or rekey protocol is active for a connection
2087 parse all packets syncronously since there might be packets
2088 in packet queue that we are not able to process without first
2089 processing packets before them. Affected file silcd/server,
2090 lib/silcclient/client.c.
2092 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2093 whether library should continue processing the packet.
2094 Affected file lib/silccore/silcpacket.h.
2096 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2124 silc_file_open and silc_file_close. Affected files
2125 lib/silcutil/silcutil.[ch].
2127 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Resolve the client info when received private message or
2130 channel message for a client which nickname we don't know.
2131 Affected files lib/silcclient/client_prvmsg.c and

2140 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2141 is incomplete and is being resolved, it won't be resolved
2144 Make sure also that USERS command reply does not resolve
2145 twice information. Affected file is
2146 lib/silcclient/command_reply.c.
2148 Make sure that silc_client_get_clients_by_list does not
2149 resolve twice same information.
2151 * Check for valid client->id in the silc_server_free_client_data.
2152 Affected file silcd/server.c.
2154 * Fixed /GETKEY nick@server not to crash if the server entry
2155 is not found. Affected file lib/silcclient/command.c.
2157 * Fixed the silc_server_check_cmode_rights to check the
2158 requested modes correctly. Affected file silcd/command.c.
2160 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Better checks for non-printable chars in nick added.
2163 Affected file silcd/command.c.
2165 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Call the silc_server_udpate_servers_by_server in the
2168 primary router that comes back online in the backup resuming
2169 protocol. Otherwise it routes packets wrong. Affected file
2170 silcd/server_util.[ch], silcd/server_backup.c.
2172 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2175 lib/silcutil/silcbuffmt.[ch].
2177 * Redefined the SILC packet header to include the padding
2178 length. Affected file lib/silccore/silcpacket.[ch].
2180 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2181 length for maximum padding up to 128 bytes). Affected
2182 file lib/silccore/silcpacket.h.
2184 * Removed all backwards support for old 0.5.x MAC thingies.
2185 The SILC packet header change makes it impossible to be
2186 backwards compatible.
2188 * Send the ENDING packet with timeout in the backup resuming
2189 protocol. This is to assure that all routers has connected
2190 to the primary router. Affected file silcd/server_backup.c.
2192 * Changed the RNG to take the first IV from random data. It
2193 used to take it from zero actually. Changed the RNG also
2194 to use /dev/urandom during session. /dev/random is used
2195 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2197 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Changed the SILC packet header to have the first two bytes
2200 (the packet length) encrypted. Affected files aroung the
2201 code tree, lib/silccore/silcpacket.[ch]. Removed the
2202 SilcPacketCheckDecrypt callback. It is not needed anymore
2203 since the silc_packet_receive_process will determine now
2204 whether the packet is normal or special.
2206 * Implemented the unidirectional MAC keys. Affected files
2207 lib/silcske/silcske.c, silcd/protocol.c and
2208 lib/silcclient/protocol.c.
2210 * Implemented the packet sequence number to the MAC computation.
2211 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2212 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2213 lib/silcclient/protocol.c.
2215 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Allow backup router to announce servers. All servers
2218 announced by backup router are added to the global list
2219 automatically. Update hte server's socket to our primary
2220 router also when backup router announces a server.
2221 Affected file silcd/packet_receive.c.
2223 * Do not update the client->router in the function
2224 silc_server_udpate_clients_by_server if the client is on
2225 global list. We might fail to find any specific server
2226 for locally connected clients and local cell clients. They
2227 should still use the `from' and not `to' as client->router.
2228 This fixes backup router resuming protocol. Affected file
2229 silcd/server_util.c.
2231 * Decrease channel statistics count only if the channel
2232 deletion worked. Affected files are silcd/server.c and
2233 silcd/server_util.c.
2235 * Added silc_server_update_servers_by_server to update origin
2236 of all server entries. Used during backup router protocol.
2237 Affected files silcd/server_util.[ch], silcd/server.c. and
2238 silcd/backup_router.c.
2240 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2241 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2242 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2243 lib/silccrypt/silchmac.c.
2245 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Assure that router cannot reroute the same channel message
2248 to the sender. Affected file silcd/packet_receive.c.
2250 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2252 * Made better checks that the channel message is not sent
2253 to the router it came from. Affected file is
2254 silcd/packet_send.c. Fixed memory leak too.
2256 * Announce informations for incoming router connection, but
2257 only after checking if it is replaced by backup router.
2258 Affected file silcd/packet_receive.c.
2260 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Fixed the backup resuming protocol to work in multiple
2263 router environment. Affected file silcd/server_backup.c.
2265 * Route packet only to one router in the function
2266 silc_server_packet_send_to_channel. Affected file is
2267 silcd/packet_send.c.
2269 * Fixed silc_server_send_notify_dest to set the broadcast
2270 flag. Fixed the silc_server_send_notify_topic to actually
2271 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2272 Affected file silcd/packet_send.c.
2274 * Changed the SFTP Filesystem interface. Changed the
2275 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2276 the filesystem operation function. The SilcSFTPFilesystem
2277 is now a context that is allocated by all filesystem allocation
2278 functions and it already includes the operations structure
2279 and filesystem specific context. It is given as argument
2280 now to the silc_sftp_server_start. This made the interface
2281 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2282 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2284 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Changed the backup router adding and getting interfaces
2287 in the server. The router that will be replaced by the
2288 specified backup router is now sent as argument. Affected
2289 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2292 * Added silc_net_addr2bin_ne to return the binary form of
2293 the IP address in network byte order. Affected files
2294 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2296 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Check for existing server ID in silc_server_new_server
2299 and in silc_server_connect_to_router_final and remove the
2300 old entry if it exists. Affected file silcd/packet_receive.c,
2303 * Send the channel message always to only one router, either
2304 in upstream or downstream. Affected file is
2305 silcd/packet_send.c.
2307 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Wrote the definition of the backup resuming protocol to the
2310 protocol specification.
2312 * Removed one redundant channel key generation from normal
2313 server during joining procedure. Removed one redundant
2314 channel key sending from server to router during joining
2315 procedure. Affected file silcd/command.c.
2317 * Made minor bugfixes to the backup router resuming protocol.
2318 Affected file silcd/server_backup.c, server.c.
2320 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Added --disable-asm configuration option. Affected files
2323 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2326 * Implemented the backup resuming protocol that is used to
2327 resume the primary router position in the cell after the
2328 primary router comes back online. Affected files
2329 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2330 and silcd/server_util.[ch].
2332 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2334 * Sleep two (2) seconds after sending QUIT command to server.
2335 Affected file lib/silcclient/command.c.
2337 * Assure that if outgoing data buffer is pending do not force
2338 send any data. Affected file silcd/packet_send.c.
2340 * Assure that if outgoing data buffer is pending do not force
2341 send any data. Affected file lib/silcclient/client.c.
2343 * Implemented the backup router support when the primary router
2344 goes down. The servers and routers can now use the backup
2345 router as new primary router without loosing connectivity.
2347 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2350 in the server to indicate disabled entry. All data read
2351 from the connection will be ignored and no data is sent
2352 for entry that is disabled. Affected files are
2353 silcd/idlist.h, silcd/server.c.
2355 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Created SFTP client and server test programs in the
2358 lib/silcsftp/tests directory.
2360 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Implemented memory filesystem (virtual filesystem) for
2363 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2366 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Implemented the SFTP (SSH File Transfer Protocol) to the
2369 lib/silcsftp. It includes SFTP client and SFTP server
2372 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Moved lib/silccore/silcprotocol.[ch] to the
2375 lib/silcutil library.
2377 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2378 take variable argument list pointer as argument. Affected
2379 file lib/silcutil/silcbuffmt.[ch].
2381 * Added silc_buffer_set function that is used to set data
2382 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2383 Affected file lib/silcutil/silcbuffer.h.
2385 * Changed various routines in the core library to use the new
2386 silc_buffer_set instead of allocating new buffer only for
2389 * Added 64-bit value formatting and unformatting support to the
2390 silc_buffer_[un]format routines. Affected file is
2391 lib/silcutil/silcbuffmt.[ch].
2393 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2394 to includes/bitmove.h.
2396 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2398 * Fixed channel user mode saving in client library. Affected
2399 file lib/silcclient/command[_reply].c.
2401 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Defined the file transfer to the SILC Protocol. Added
2404 new packet type SILC_PACKET_FTP and defined File Transfer
2405 Payload. The mandatory file transfer protocol is SFTP
2406 (SSH File Transfer Protocol). Affected file in addition
2407 of the internet draft is lib/silccore/silcpacket.h.
2409 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2410 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2411 is used as part of backup router protocol when the primary
2412 router of the cell is back online and wishes to resume
2413 the position as primary router.
2415 * Redefined the MAC generation keys in the protocol. The
2416 same key is not used anymore in both direction. Both
2417 direction will now use different keys for sending and
2418 receiving. This fixes a potential security flaw. This
2419 change causes incompatibilities in the protocol.
2421 * Redefined also the MAC computation from the packet.
2422 An packet sequence number is now added to the MAC
2423 computation. This prevents possible replay attacks against
2424 the protocol. This change too causes incompatibilities
2427 Added `sequence' field to the SilcPacketContext to hold
2428 the current sequence number for the packet.
2430 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Added `created' field to the SilcIDListData in the file
2433 silcd/idlist.h to indicate the time when the entry was
2436 * Added `created' field to the SilcChannelEntry too. Affected
2437 file silcd/idlist.h.
2439 * Added `creation_time' aguments to all the announcement functions
2440 in the server. If it is provided then only the entries that
2441 was created after the provided time frame are actually
2442 announced. Affected file silcd/server.[ch].
2444 * The protocol says that the Channel ID's IP address must be
2445 based on the router's IP address. Added check for this in
2446 the silc_server_new_channel when processing incoming New Channel
2447 Payload. Affected file silcd/packet_receive.c.
2449 * Print out the correct version with --version in SILC client.
2450 Affected file irssi/src/silc/core/silc-core.c.
2452 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Fixed WHOWAS command to check for completnes of the client
2455 entry always, not just when the command is coming from client.
2456 Affected file silcd/command.c.
2458 * Added new function silc_server_packet_queue_purge to purge the
2459 outgoing data queue to the network. After the function returns
2460 it is guaranteed that the outgoing packet queue is empty.
2461 Affected file silcd/packet_send.[ch].
2463 * Purge the outgoing packet queue in the rekey protocol's final
2464 callback to assure that all rekey packets go to the network
2465 before quitting the protocol. Affected file silcd/server.c.
2467 * Added silc_client_packet_queue_parse as similar function as
2468 in server to the client library. The affected file is
2469 lib/silcclient/client.c.
2471 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Splitted silcd/server.c and created silcd/server_util.[ch]
2474 for utility functions.
2476 * Added new socket flag SILC_SF_DISABLED to indicate that the
2477 connection is open but nothing can be sent to or received from
2478 the connection. Affected file lib/silcutil/silsockconn.[ch].
2479 The checking for disabled socket is checked in the low level
2480 silc_socket_write and silc_socket_read functions.
2482 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Allow only nicknames and channel names that fits into the
2485 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2487 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * When processing JOIN command reply in server check that if
2490 the channel exists in our global list we'll move it the local
2491 list. Affected file silcd/command_reply.c.
2493 * Fixed the check whether client is joined on the channel already
2494 in JOIN command. Affected file lib/silcclient/command.c.
2496 * Fixed the JOIN command reply to check whether the channel
2497 already exists. Affected file lib/silcclient/command_reply.c.
2499 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Added silc_ske_status_string to map the SKE error numbers
2502 to readable strings. The affected files are
2503 lib/silcske/silcske[_status].[ch].
2505 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2507 * Do not show the private channels on the WHOIS channel list
2508 as it is not allowed by the protocol. The affected file is
2511 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Assure that the packet length digged from the actual packet
2514 is something sensible in the silc_packet_decrypt_rest_special
2515 in lib/silccrypt/silcpacket.c.
2517 * Free and NULL the allocated pointer in silc_hmac_alloc if
2518 the HMAC allocation fails. The affected file is
2519 lib/silccrypt/silchmac.c.
2521 * Print the selected security properties to the log files in
2522 the server. Affected file silcd/protocol.c.
2524 * Add SKE's reference counter even if calling the completion
2525 callback manually. Otherwise it goes negative, although it
2526 does not cause any problems. The affected file is
2527 lib/silcske/silcske.c.
2529 * Remove the client entry with short timeout after giving the
2530 KILL command. Affected file lib/silcclient/command.c.
2532 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2533 case all found clients are already disconnected (WHOWAS would
2534 found them) in the server. Affected file silcd/command.c.
2536 * Update the last_receive (time of last data received) to be
2537 updated only when received private or channel message so that
2538 the idle time showed in WHOIS makes more sense.
2540 * Added boolean field `valid' in to the SilcClientEntry in the
2541 client library to indicate whether the entry is valid or not.
2542 This fixes the nickname change bug on channel when changing
2543 the nickname to be same than the old (like nick to Nick) the
2544 nickname formatter doesn't set the new nick anymore to Nick@host.
2545 Affected file lib/silcclient/idlist.[ch].
2547 * Now actually fixed the nickname changing on disconnection.
2548 Added new function silc_change_nick to the Irssi SILC Client.
2549 Affected file irssi/src/silc/core/client_ops.c,
2550 irssi/src/silc/core/silc-nicklist.[ch].
2552 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Check that the public key exists in the GETKEY command before
2555 trying to encode it. Affected file silcd/command.c.
2557 * Print some notifications on received public keys with GETKEY
2558 command in the Irssi SILC Client. Affected files are
2559 irssi/src/fe-common/silc/module-formats.[ch],
2560 irssi/src/silc/core/client_ops.c.
2562 * Use IDENTIFY command to resolve the server information in the
2563 GETKEY command instead of INFO command. Affected file
2564 lib/silcclient/command.c.
2566 * All command reply functions in the client library now calls
2567 the pending command reply callbacks even if an error has
2568 occurred. The server has done this a long time and now it was
2569 time to move the client library to this as well. Now all
2570 errors can be delivered back to the pending command reply
2571 callbacks if necessary. Affected files are
2572 lib/silcclient/command[_reply].[ch].
2574 * Change the nickname on disconnection back to the username
2575 because in reconnect the server will enforce it to it anyway.
2576 Affected file irssi/src/silc/core/silc-servers.c.
2578 * Fixed a config file parsing bug in the Irssi SILC client.
2579 Affected file irssi/src/silc/core/clientconfig.c.
2581 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * When printing the channel mode on JOIN, verify that the
2584 channel key and channel's HMAC are valid. Affected file
2585 irssi/src/silc/core/client_ops.c.
2587 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2590 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2591 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2593 * Removed channel key rekey task deleting from the function
2594 silc_server_save_channel_key. Affected file silcd/server.c.
2595 Added explicit timeout task context instead that is used to
2596 delete the task if we are registering a new task before the
2597 new task has elapsed.
2599 * When channel key rekey occurs the client library now saves
2600 the old channel key for a short period of time (10 seconds) and
2601 is able to use it in case some is still sending channel
2602 messages encrypted with the old key after the rekey. Affected
2603 file lib/silcclient/[idlist.h|client_channel.c].
2605 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2607 * Added check to the silc_server_new_id_real to not accept
2608 new ID if it is the sender's own ID. Affected file is
2609 silcd/packet_receive.c.
2611 * Assure that we do not announce ourself or the one we've
2612 sending our announcements when we're router and are announcing
2613 servers to our primary router. Affected file silcd/server.c.
2615 * Fixed silc_server_command_identify_check_client to assemble
2616 correct WHOIS packet. It send corrupted WHOIS packet and
2617 caused problem with router to router connections. Affected
2618 file silcd/command.c.
2620 Fixed also silc_server_command_whois_check the same way
2621 as for the IDENTIFY command.
2623 * Added new SilcIDListStatus to the server in the SilcIDListData
2624 structure. The status now includes the current status of
2625 the entry (like registered, resolved etc.). Affected file
2626 silcd/idlist.[ch]. Defined a bunch of different status types
2627 as well. This replaced the old boolean registered field as well.
2629 Added resolve_cmd_ident field to the SilcClientEntry structure
2630 too so that if the entry is for example being resolved so
2631 another command may attach to the same pending command reply
2632 without requiring to resolve the same entry again. This concept
2633 should optimize the WHOIS and the IDENTIFY resolving under
2634 heavy load by taking away unnecessary resolving for entries
2635 that are being resolved already.
2637 Added support for adding multiple pending commands for one
2638 command idenfier. Affected file silcd/command[_reply].[ch].
2640 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2641 before deleting the data. Otherwise the hash table will have
2642 freed data in comparison functions. Affected file is
2643 silcd/command_reply.c.
2645 * Fixed silc_idlist_replace_client_id to add the new entry to
2646 the cache with NULL nickname. Otherwise there will be invalid
2647 memory as the nickname after the nickname is freed. Affected
2648 file silcd/packet_receive.c.
2650 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2651 saved into wrong slots because the previous number of entries
2652 was not taken into account. Affected file silcd/idlist.c.
2653 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2655 * If we are router and we receive JOIN notify to a channel that
2656 does not have any users then notified client is marked as the
2657 channel founder, as it is it. The affected file is
2658 silcd/packet_receive.c
2660 * Added to the extended hash table API's table_del_*ext functions
2661 the destructor as argument too, so that the caller can decide
2662 which destructor to use or whether to use destructor at all.
2663 Affected file lib/silcutil/silchashtable.[ch].
2665 * Fixed ID Cache purging. It actually deleted the entries from
2666 the hash table after the data was freed. The hash table ended
2667 up comparing freed memory. The affected file is
2668 lib/silccore/silcidcache.c.
2670 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * Fixed Irssi SILC client's KILL command's HELP syntax.
2674 * The USERS command now resolves the detailed user information
2675 if the userinfo field is missing. Affected file is
2676 lib/silcclient/command_reply.c.
2678 * Do not print error in silc_file_read if the read file does
2679 not exist. Just silently return NULL. Affected file is
2680 lib/silcutil/silcutil.c.
2682 * Fixed the silc_log_output to not wine about NULL filename
2683 and to not create some bogus " " filename. Affected file is
2684 lib/silcutil/silclog.c.
2686 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Fixed various printing bugs on the user interface in the
2689 Irssi SILC Client. Minor changes that were forgotten from
2692 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Fixed the configure.in.pre and the compilation and distribution
2695 environment to support the new autoconf 2.52. That version is
2696 now required to compile the CVS trunk.
2698 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2701 to generally parse user@fqdn format strings. Affected file
2702 lib/silcutil/silcutil.c.
2704 * Added nickname_format and nickname_force_format fields to the
2705 SilcClientParams structure. The first one defines the format
2706 for the nicknames that the library will enforce if the receives
2707 multiple same nicknames. The second one is boolean value and
2708 can be used to force the library to always enforce the format
2709 to the nicknames regardles whether there are multiple nicknames
2710 or not. This configurable formatting was employed to flexibly
2711 support accessing multiple nicknames from the user interface.
2712 The userinterface can now set the nicknames to what ever format
2713 they prefer. Affected file lib/silcclient/silcapi.h.
2715 Added function silc_client_nickname_format to the file
2716 lib/silcclient/idlist.c. It performs the nickname formatting.
2718 Added new field `hostname´ to the SilcClientEntry context.
2719 It holds the hostname of the client. Affected file is
2720 lib/silcclient/idlist.h.
2722 * Irssi SILC Client sets the nicknames in nick@hostn format.
2723 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2724 irssi/src/silc/core/silc-core.c.
2726 The WHOIS printing now also shows both the real nickname and
2727 the formatted nickname so that user knows how to access the
2728 user if there are multiple same nicknames cached. Affected
2729 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2730 printing formatting too to take the hostname now as a separate
2731 argument. The Affected file is
2732 irssi/src/fe-common/silc/modules-formats.[ch].
2734 * Changed the silc_client_get_clients_local to accept the formatted
2735 nickname as argument. It accepts the real nickname too but the
2736 formatted nickname can be used to find the true entry from
2737 multiple entries. Affected file lib/silcclient/silcapi.h and
2738 lib/silcclient/idlist.c.
2740 * Added nickname_format_parse field to the SilcClientParams.
2741 It is a callback function provided by the application to parse
2742 the nickname out of the formatted nickname string. The library
2743 calls it to get the nickname from the formatted string. Since
2744 the application generally knows better the format of the nickname
2745 string it parses it instead of the library, even though library
2746 encodes the formatted string. If the callback function is not
2747 provided then the library will use the string as is. The
2748 affected file is lib/silcclient/silcapi.h.
2750 * All the nickname strings passed to the client library in
2751 commands are now expected to be formatted nickname strings.
2752 If the command does not support the formatted nickname string
2753 it will assume that the sent string is the actual nickname.
2754 Affected file lib/silcclient/command.c.
2756 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2758 * Added public key authentication support to OPER and SILCOPER
2759 commands in the client library. Affected file is
2760 lib/silcclient/command.c.
2762 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Changed the get_auth_methdod client operation to be asynchronous.
2765 It can be async if the application resolves the authentication
2766 method from the server during the negotiation. Added new
2767 SilcGetAuthMeth completion callback that the application will
2768 call after resolving the authentication method.
2770 Added function silc_client_request_authentication_method that
2771 the application can use to resolve the authentication method
2772 from the server. Added also SilcConnectionAuthRequest callback
2773 that the library will call after the server has replied. The
2774 application can call this function if it does not know the
2775 current authentication method.
2777 Affected files are lib/silcclient/client.c and
2778 lib/silcclient/silcapi.h.
2780 * The Irssi SILC client now automatically resolves the authentication
2781 method incase any configuration information is not present (and
2782 currently there never is). The affected file is
2783 irssi/src/silc/core/client_ops.c.
2785 * Fixed public key authentication from the client library.
2786 Affected file lib/silcclient/protocol.c. Changed also the
2787 protocol specification about the public key authentication in
2788 the connection authentication protocol. The actual data to be
2789 signed is now computed with a hash function before signing.
2791 * Fixed the public key authentication from the server as well.
2792 Affected file silcd/protocol.c.
2794 * Removed the mlock()'s from the memory allocation routines.
2795 Affected file lib/silcutil/silcmemory.c. The ./configure does
2796 not check anymore for the mlock(). Affected file is
2799 * Fixed USERS command in server to allow the execution of the
2800 command for private and secret channels if the client sending
2801 the command is on the channel. Affected file silcd/command.c.
2803 * Fixed silc_client_get_clients_local to return the clients
2804 count correctly. It could return wrong value. Affected file
2805 lib/silcclient/idlist.c.
2807 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2809 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2810 types. The assembler optimizations seemed not to like 64-bit
2811 data types. The assmebler optimizations thus are now enabled
2812 also for BSD systems as opposed to only enable them for Linux.
2814 * Do not check for threads at all on BSD systems. Affected
2815 file configure.in.pre.
2817 * Removed -n and -h options from the Irssi SILC Client since
2818 they are not used in silc.
2820 * Fixed the prime generation to assure that the first digit
2821 of the generated random number is not zero since our conversion
2822 routines does not like number strings that starts with zero
2823 digit. If zero digit is seen the random number is regenerated.
2824 This caused some corrupted RSA keys when the zero first digit
2825 was met. Affected file lib/silcmath/silcprimegen.c.
2827 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Fixed WIN32 configuration in the ./configure script.
2830 Fixed to include xti.h on environments that has it.
2831 Patches by Carsten Ilchmann and andrew.
2833 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Changed the silc_id_create_client_id to be collision
2836 resistant. It is now assured that there cannot be created
2837 two same client ID's. I suspect that some weird bugs in
2838 the server were actually caused by duplicate Client IDs.
2839 Affected file silcd/serverid.[ch]. A router receiving
2840 new ID now also assures and informs the sending server
2841 if the ID caused collision.
2843 * Changed the silc_id_create_channel_id to also assure that
2844 there are no collisions.
2846 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Statement about ignoring the Mutual Authentication flag when
2849 performing rekey with PFS was a bit misleading. It is ignored
2850 if it was set in the initial negotiation, it cannot be even
2851 set in the rekey. Fixed in the ke-auth draft. Started the
2852 new versions of the protocol drafts in the doc/.
2854 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Fixed a bug in silc_client_command_identify_save when saving
2857 new channel information. The channel name was no duplicated
2858 and caused crash on exit. Affected file is
2859 lib/silcclient/command_reply.c.
2861 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Fixed the getkey command handling in the server. Send just
2864 empty OK reply to the sender if the key could not be fetched
2865 (but everything else was ok, like the key just was not available).
2866 Changed the public key parameter to optional in the protocol
2867 specs so that empty OK reply can be sent. Affected file
2870 Added a message to Irssi SILC client to tell to user if the
2871 server did not return a public key.
2873 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Fixed a channel key regeneration bug. It registered new
2876 timeout tasks exponentially until all system resources were
2877 used. Affected file silcd/server.c.
2879 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Added the SILC Document generator to the scripts/silcdoc.
2882 It can be used to generate the Toolkit Reference Manual out
2883 of the source tree. Internally it will also use the RoboDoc
2884 generator now imported in util/robodoc.
2886 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2888 * Added couple of return's in rekey protocol if error orccurred
2889 during the protocol. The execution must be terminated.
2890 Affected file silcd/protocol.c. Also, terminate the protocol
2891 always with timeout.
2893 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * The client's Client ID was created initally from the wrong
2896 nickname (it could have been in format nick@host) in the
2897 silc_server_new_client. Affected file silcd/packet_receive.c
2899 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Added some SILC_LOG_ERROR's to various error conditions
2902 if client could not be added to ID cache. Affected files
2903 silcd/packet_receive.c and silcd/server.c.
2905 * When client's sock->user_data is freed, NULL also the
2906 client->router and client->connection pointers. Added check
2907 for these pointers being NULL to various places around the
2908 code. Affected file silcd/server.c.
2910 * Added client->data.registered == TRUE checks to various
2911 places around the code to assure that unregistered client's
2912 are not handled when it is not allowed. Affected file
2915 * Added `bool registered' fields to all
2916 silc_idlist_[server|client]_get_* routines to indicate whether
2917 the fetched client needs to be registered or not. Affected
2918 file silcd/idlist.[ch].
2920 * Add your own entry as registered to the ID cache in the
2921 server. Affected file server.c.
2923 * Fixed a bug in silc_server_new_server. The SilcServer was
2924 set as the new server's context instead of SilcServerEntry.
2925 This naturally caused some weird bugs.
2927 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Do not delete the channel rekey task when adding it
2930 for in silc_server_create_channel_key.
2932 * Changed the silc_server_create_channel_key to return
2933 TRUE or FALSE to indicate the success of the channel key
2936 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Fixed MSVC++ project files and added missing files to
2939 Makefiles under win32/.
2941 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Do not add TCP_NODELAY flag if the operating system
2944 does not have it defined. Affected files are
2945 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2947 * Fixed buffer overflow from Irssi SILC Client. Affected
2948 file irssi/src/fe-common/core/themes.c.
2950 * Fixed double free in client library in the file
2951 lib/silcclient/client.c when disconnecting from server.
2953 * Applied double free patch from cras to Irssi SILC client.
2954 Affected files irssi/src/core/[modules/expandos].c
2956 * Fixed the disconnection handling to Irssi SILC Client.
2957 The application must call silc_client_close_connection
2958 in ops->connect client operation in case of failure of
2959 the connection. Affected file is
2960 irssi/src/silc/core/client_ops.c.
2962 * Do not set sock->protocol to NULL in the function
2963 silc_client_close_connection after executing the protocol's
2964 final callback since the sock might not be valid anymore.
2965 Affected file lib/silcclient/client.c.
2967 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Do not enable SILC_THREADS if the linking with libpthread
2970 did not happen. Affected file configure.in.pre.
2972 * Added notion to protocol specification that server must
2973 verify the sent authentication payload with CMODE when
2974 setting the channel founder key. Implemented it to the
2975 server. Affected file silcd/command.c.
2977 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Added _EXTRA_DIST SILC distribution variable to the
2980 distributions file. It is used to conditionally add extra
2981 files or directories to the specific distribution. Affected
2982 files ./prepare, Makefile.am.pre and distributions.
2984 Removed the `_' from the start of the distribution names.
2987 * Added README.WIN32 for instructions to compile the Toolkit
2990 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Fixed a double free in disconnection in the server. Affected
2993 file is silcd/server.c.
2995 * Fixed the lib/silcske/groups.c to work now also with GMP
2996 MP library. The string conversion did not work when using
2997 specific base and the base is indicated in the string as well.
2999 * Created win32/ directory which now includes MSVC++ specific
3000 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3001 It will appear only in the toolkit distribution
3003 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Changed the key material distribution function in case when
3006 the hash output is too short. The data is now concatenated
3007 a bit differently than it used to. Made the change to the
3008 SKE protocol specification.
3010 * Added better GMP detection to configure.in.pre. A patch
3013 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Fixed a minor bug in SKE that might cause some problem on
3016 some platforms. Affected file lib/silcske/silcske.c.
3018 * Added the cookie checking for initiator in the SKE. It checks
3019 that the responder returns the sent cookie unmodified. The
3020 affected file is lib/silcske/silcske.c. Added new SKE
3021 error type INVALID_COOKIE that can be sent during the
3022 negotiation. Fixed some memory leaks as well.
3024 * Added the "invalid cookie" error message to Irssi SILC client's
3027 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Added `task_max' field to the SilcClientParams to indicate
3030 the maximum tasks the scheduler can handle. If set to zero,
3031 default values are used. Affected file lib/silcclient/silcapi.h.
3033 * Fixed memory leaks in silc_client_close_connection. Affected
3034 file lib/silcclient/client.c.
3036 * Added silc_client_del_client_entry to client library to free
3037 all memory of given client entry. Affected file is
3038 lib/silcclient/idlist.[ch].
3040 * Added new functions silc_client_del_channel and
3041 silc_client_del_server to delete channel and server entries.
3042 Affected file lib/silcclient/[silcapi.h/idlist.c].
3044 * Removed silc_client_del_client_by_id from silcapi.h.
3046 * Fixed the INFO command to return the server's own info
3047 correctly when querying by Server ID. Affected file is
3050 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3052 * Removed the non-blocking settings in WIN32 code in the
3053 silc_sock_[read/write] and added SleepEx instead. Affected
3054 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3055 of input data is now checked with FIONREAD and ioctlsocket.
3057 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3059 * Call silc_schedule_task_del_by_context in the
3060 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3061 Affected file lib/silccore/silcprotocol.c.
3063 * Call silc_protocol_cancel for active protocols in the
3064 silc_server_close_connection if the funtion
3065 silc_server_free_sock_user_data has not been called.
3066 Affected file silcd/server.c.
3068 * Generic tasks cannot be deleted using the del_by_fd
3069 task deleting function since generic tasks does not match
3070 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3072 * Added a notion to SILCOPER help file that the SILCOPER works
3073 only on router server, not on normal server.
3075 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Added for WIN32 support for the new scheduler as well.
3078 Affected file lib/silcutil/win32/silcwin32schedule.c.
3080 * Fixed the SHA1 implementation to work on various platforms.
3082 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3085 API. It is part of the scheduler now. Everything else is
3086 as previously but some functions has changed their names.
3087 Checkout the lib/silcutil/silcschedule.h for the interface.
3088 Updated all applications to use the new interface. Affected
3089 files are lib/silcutil/silcschedule.[ch].
3091 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Found a bug in the SKE implementation. The HASH value,
3094 specified by the protocol, was not computed correctly. The
3095 public key of the responder was not added to the computation
3096 even though it is mandatory. Affected file lib/silcske/silcske.c.
3097 This unfortunately causes incompatibilities with older
3098 clients and servers.
3100 * Added WIN32 specific network init and uninit functions:
3101 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3102 the Winsock2. Affected file lib/silcutil/silcnet.h and
3103 lib/silcutil/win32/silcwin32net.c.
3105 * Set the socket always to nonblocking mode on WIN32 after
3106 reading data or writing data. Affected file is
3107 lib/silcutil/win32/silcwin32sockconn.c.
3109 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Fixed various compilation problems under WIN32. Affected
3112 files lib/silcutil/win32/silcwin32thread.c and
3113 lib/silcutil/win32/silcwin32schedule.c.
3115 * Removed all _internal.h #includes from public header
3116 files. Internal headers must never be included from
3119 Removed also the lib/silcske/payload_internal.h file.
3121 * All include files that may be needed (public and some others
3122 included by the public headers) by application developers are
3123 now copied to the ./includes directory. It does not copy any
3124 internal headers. Affected file Makefile.defines.pre and all
3125 Makefile.am's under lib/ and subdirs.
3127 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3129 * Do not change the ~/.silc directory's permissions automatically.
3130 Affected file irssi/src/silc/core/clientutil.c.
3132 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Do not cancel the protocol in silc_server_close_connection
3135 it might cause recursion. Now cancelled in the function
3136 silc_server_free_sock_user_data. Affected file silcd/server.c.
3138 * Fixed the silc_server_remove_clients_by_server to regenerate
3139 the channel keys correctly finally. Added also new function
3140 silc_server_remove_clients_channels to actually do it.
3141 Affected file silcd/server.c.
3143 * Fixed the silc_server_new_channel to not crash by giving
3144 wrong router to the new channel. Affected file is
3145 silcd/packet_receive.c.
3147 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3149 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3150 which is given as argument to the silc_client_alloc now.
3151 It can be used to configure the client and set various parameters
3152 that affect the function of the client.
3154 * The USERS command in server did not check whether the channel
3155 is private or secret. Affected file silcd/command.c.
3157 * Added new argument to the USERS command in protocol specification.
3158 The USERS command now can take the channel name as argument
3159 as well. Added support for this in client and server and
3160 updated the protocol specs.
3162 * Completed the GETKEY command in client. It can be now used
3163 to fetch also servers public key not only some clients.
3164 Affected files lib/silcclient/command[_reply].c.
3166 * Added silc_client_get_server to return server entry by the
3167 server name. Affected files lib/silcclient/silcapi.h and
3170 * Redefined the IDENTIFY command in protocol specification to be
3171 more generic. It now can be used to query information about
3172 any entity in the SILC Network, including clients, servers and
3173 channels. The query may be based either the entity's name
3174 or the ID. Added support for this in both client and server.
3176 Affected files silcd/command.c and lib/silcclient/command.c
3177 and command_reply.c.
3179 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3180 the _from_client and _from_server functions. Affected file
3183 * Added silc_client_get_channel_by_id_resolve to the file
3184 lib/silcclient/silcapi.h to resolve channel information by
3185 its ID. Added also silc_client_get_channel_by_id that
3186 does not resolve it from the server.
3188 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Added SilcServerEntry context into the client library
3191 to represent one server. The INFO command now allocates
3192 these to save the resolved server info. For now on the
3193 client library will also keep information about servers,
3194 connected and resolved with INFO.
3196 The INFO command now allocates the SilcServerEntry context
3197 and saves the server info there. The COMMAND_REPLY in
3198 the INFO now returns the parameters to application in
3199 same order as defined in the protocol specification.
3201 The entries are cached in the client->server_cache.
3203 * The INFO command is now issued after received the Client ID
3204 from the server. Affected file lib/silcclient/client.c.
3206 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3207 to the application as the mode changer might be server.
3208 It is guaranteed that NULL is not returned anymore to the
3209 application. Affected file lib/silcclient/client_notify.c.
3211 The ID Type is now also passed to the application so that
3212 it can check whether the returned entry is SilcClientEntry
3215 Added new function silc_client_get_server_by_id to return
3216 the server entry by ID. Affected files are the
3217 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3219 * Do not create the channel in the Irssi SILC Client when issuing
3220 the JOIN command but when received the sucessful JOIN command
3221 reply. Otherwise the channel might get created even though we
3222 could not join it. The Affected file is
3223 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3225 * Fixed a channel joining bug in router. The router must also
3226 check the channel modes, invite and ban lists etc. when serving
3227 the JOIN command sent by normal server. Affected file is
3228 silcd/command.c. The router now resolves the client's
3229 information from the server who sent the JOIN command if it
3230 does not know it, and processes the JOIN command only after
3233 * Changed the SilcCommandCb to take new argument; void *context2.
3234 Affected file lib/silccore/silccommand.h
3236 The second argument in the command callbacks in the server now
3237 includes the SilcServerCommandReplyContext if the command was
3238 called as pending command callback from the command reply.
3239 Otherwise it is NULL. When called as pending the status of the
3240 command reply will be checked and if it was erronous the
3241 error will be sent to the original sender of the command.
3242 This way the client always receives the error messages even
3243 though the server was actually the one who received the error
3244 when it resent the command to router, for example. Affected
3245 files silcd/command[_reply].[ch].
3247 * Fixed sending WHOWAS command's error message to client if
3248 the requested client could not be found. It was missing.
3251 * Changed the CMODE and CUMODE commands reply arguments in the
3252 protocol specification. The Channel ID is now sent in both
3253 of the commands to identify the channel. Implemented this
3254 new feature to the client and server. Affected files
3255 lib/silcclient/command_reply.c and silcd/command.c.
3257 * Made better checks for invite and ban lists in the JOIN
3258 command in server. Affected file silcd/command.c.
3260 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * The server now performs the incoming host IP/DNS lookup
3263 using the silc_socket_host_lookup and thus does not block
3264 the server anymore. Affected file silcd/server.c.
3266 * Completed the multi-thread support for SILC Scheduler in
3267 the lib/silcutil/silcschedule.c.
3269 * Fixed the configure.in.pre to detect the pthread correctly
3272 * Fixed a deadlock in silc_task_queue_wakeup in the file
3273 lib/silcutil/silctask.c.
3275 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Added new function silc_schedule_wakeup that is used in
3278 multi-threaded environment to wakeup the main thread's
3279 schduler. It needs to be used when a thread adds a new task
3280 or removes a task from task queues. After waking up, the
3281 scheduler will detect the task queue changes. If threads
3282 support is not compiled in this function has no effect.
3283 Implemented the wakeup mechanism to both Unix and WIN32
3284 systems. Affected files are lib/silcutil/silcschedule.[ch],
3285 lib/silcutil/unix/silcunixschedule.c and the
3286 lib/silcutil/win32/silcwin32schedule.c.
3288 * Added new function silc_task_queue_wakeup to wakeup the
3289 scheduler by the specified task queue. Affected file
3290 lib/silcutil/silctask.[ch].
3292 * The silc_socket_host_lookup_start now wakes up the scheduler
3293 after adding the timeout task. Affected file is
3294 lib/silcutil/silcsockconn.c.
3296 * The silc_socket_host_lookup is synchronous now if the threads
3297 support is not compiled in. However, the callback is still
3298 called asyncronously through the scheduler, anyway. Affected
3299 file lib/silcutil/silcsockconn.c.
3301 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Added new function silc_socket_host_lookup to perform
3304 asynchronous IP and FQDN lookups for the socket connection.
3305 Affected files lib/silcutil/silcsockconn.[ch].
3307 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3309 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3310 that may or may not compile the mutex support in.
3312 Changed the silc_mutex_alloc interface. It allocates the
3313 mutex now to the sent pointer and returns TRUE or FALSE.
3315 Affected file lib/silcutil/silcmutex.h.
3317 * Wrote the SILC Task Queue interface to support multi-threads.
3318 Affected file lib/silcutil/silctask.[ch].
3320 * Wrote the SILC Scheduler to support multi-threads. Affected
3321 file lib/silcutil/silcschedule.c.
3323 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3326 in lib/silcutil/win32/.
3328 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Defined SILC Mutex API and SILC Thread API and implemented
3331 them for Unix. Affected files are
3332 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3333 lib/silcutil/unix/silcunixmutex.c and
3334 lib/silcutil/unix/silcunixthread.c.
3336 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Fixed the silc_server_remove_clients_by_server's channel
3339 key re-generation. The hash table handling was incorrect
3340 and would not work with many channels. Affected file is
3343 * Fixed some memory leaks around the server code.
3345 * Rewrote the silc_server_get_users_on_channel to support IPv6
3346 based Client ID's. Affected file silcd/server.c.
3348 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3349 specification. However, a separate document must be written
3350 to define the detailed signing procedure and the payload
3351 associated with the flag. Defined the flag to the
3352 lib/silccore/silcchannel.h as well.
3354 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3356 * Changed the dynamic tables to static size tables in the
3357 lib/silccrypt/silchmac.c.
3359 * Removed GCC dependencies from the code. A patch by cras.
3361 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Do not show the error "Error receiving packet bla bla"
3364 in server if it really was not an error (-2 means that reading
3365 is pending). Affected file silcd/server.c.
3367 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Fixed a possible crash in silc_server_remove_clients_by_server
3370 in silcd/server.c. Fixed there also some memory leaks.
3372 * Fixed the silc_idlist_replace_client_id. It could replace
3373 wrong key in the hash table. Affected file silcd/idlist.c.
3375 * Do not check whether there are global users on the channel
3376 if the channel->global_users is FALSE. Affected functions
3377 silc_server_remove_from_one_channel and
3378 silc_server_remove_from_channels in silcd/server.c. Also,
3379 do not check if the removed client is local as we can be
3380 sure that global client was not removed from the channel
3381 and checking for global users is not needed.
3383 * The silc_server_remove_clients_by_server now re-generates
3384 the channel keys correctly for those channels that had
3385 clients removed from them. Affected file silcd/server.c.
3387 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Found the reason of random crashes in the server. We weren't
3390 ignoring the SIGPIPE signal (which can be sent in write())
3391 and it crashed the server. Affected file silcd/silcd.c.
3393 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Assure that sock->user_data is not NULL in the function
3396 silc_server_packet_send in silcd/packet_send.c.
3398 * Disconnect the remote connection if it could not be added
3399 to any ID lists in the server. The affected file is
3402 * Check in silc_server_packet_send[_real/dest] that the
3403 socket is not disconnecting and ignore the data if it is.
3404 Affected file silcd/packet_send.c.
3406 * Define inline to __inline on native WIN32 compilation.
3407 Affected file includes/silcwin32.h.
3409 * Added some explicit type casts for inline code since MSVC
3410 require them. Affected files lib/silcutil/silcbuffer.h,
3411 lib/trq/silcdlist.h and lib/trq/silclist.h.
3413 * Print warning in log files from now on if the packet
3414 decryption fails. Affected file silcd/server.c.
3416 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3418 * Changed the `say' client operation's interface to accept
3419 new `type' argument to indicate the type of the message sent
3420 by the library. The application may filter the library's
3421 messages according the type. The affected file is the
3422 lib/silcclient/silcapi.h.
3424 * Added two new functions to lib/silcclient/silcapi.h:
3425 silc_client_del_client and silc_client_del_client_by_id.
3426 Affected file lib/silcclient/idlist.c.
3428 * Moved the clientincludes.h from includes/ to silc/ and
3429 serverincludes.h from includes/ to silcd/.
3431 * The modes for the CMODE and CUMODE are now passed as
3432 uint32 for application with COMMAND_REPLY. The affected
3433 file is lib/silcclient/command_reply.c.
3435 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * /WHOIS without arguments shows client's own information.
3438 Affected file lib/silcclient/command.c.
3440 * Changed PING to not accept any arguments. The specs
3441 says that client can ping only the connected server so
3442 requiring an argument is not needed. Affected file is
3443 lib/silcclient/command.c.
3445 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Fixed a fatal bug in private message sending and reception
3448 encryption and decryption when using private message keys.
3449 The implementation was incorrect and did not follow the
3450 specification. It causd that some of the message were
3451 lost since it did not use the sending and receiving keys
3452 as the protocol suggests. This has been fixed and will cause
3453 incompatibilities with older clients when sending private
3454 message encrypted with private message keys. Affected files
3455 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3456 and various other in Irssi SILC Client.
3458 Added `responder' boolean argument to the functions
3459 silc_client_add_private_message_key[_ske] to indicate when
3460 the key is added as responder or initiator of the key
3463 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * Removed the silc_ske_check_version function and created
3466 a SilcSKECheckVersion callback. Added also a function
3467 silc_ske_set_callbacks that is now used to set all SKE
3468 callbacks. The callback functions are not given to
3469 the SKE functions anymore, but this function is used to
3472 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3474 * Added `silc_version' argument to the silc_client_alloc
3475 to define the version of the application for the library.
3476 The library will use the version string to compare it
3477 against the remote host's (usually a server) version
3478 string. Affected file lib/silcclient/silcapi.h
3480 * Added the KE protocol context to Key Agreement context
3481 in client library so that we can abort the SKE if it
3482 is in process when we get timeout. Affected file is
3483 lib/silcclient/client_keyagr.c.
3485 * Do not resolve the client ID forever if it returns in the
3486 first time that such client does not exist. This was done
3487 for example with private message. Affected file is
3488 lib/silcclient/client_prvmsg.c.
3490 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3492 * Do not add regex.h for WIN32. The affected file
3493 includes/silcincludes.h.
3495 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3496 not work yet 100%. It generates the DLL's automatically
3497 when compiling with --with-win32 under cygwin.
3499 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * lib/contrib/regex.c is not compiled on WIN32.
3503 * Added silc_net_get_socket_opt function to the
3504 lib/silcutil/silcnet.h.
3506 * Added includes/silcwin32.h for WIN32 specific includes
3509 * Do not use ptime structure or any of the posix process
3510 functions on WIN32 in lib/silccrypt/silrng.c.
3512 * Added silc_gettimeofday to provide generic function
3513 for struct timeval on all platforms. Added the function
3514 to lib/silcutil/silcutil.h.
3516 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3519 library as they clearly belong there. As a plus side we
3520 can make the actual socket connection routines platform
3523 Added also new generic function silc_socket_read and
3524 silc_socket_write (that used to be silc_packet_[read/write].
3525 The implementation of these are platform specific.
3527 * Added WIN32 specific routines of silc_socket_[read/write]
3528 to lib/silcutil/win32/silcwin32sockconn.c.
3530 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Added preliminary support for native WIN32 compilation under
3533 cygwin (using the -mno-cygwin option for GCC) to the
3534 ./configure.in.pre. The --with-win32 now prepares the
3535 compilation for native WIN32.
3537 * Rewrote the SILC Scheduler interface in the file
3538 lib/silcutil/silcschedule.h. The scheduler is now context
3539 based and does not have anymore any global static scheduler.
3540 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3541 and created lib/silcutil/win32 directory for WIN32 based
3544 * Added Unix specific network routines to the
3545 lib/silcutil/unix/silcunixnet.c and the old
3546 lib/silcutil/silcnet.c includes now only generic routines.
3548 Added WIN32 specific network routines to the
3549 lib/silcutil/win32/silcwin32net.c.
3551 * Added Unix specific utility functions from the
3552 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3554 * Added WIN32 SILC Scheduler to the file
3555 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3558 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Do not handle JOIN notify in the server if the target client
3561 is not registered (idata->registered == FALSE). The affected
3562 file is silcd/packet_receive.c.
3564 * Update the nickrec->founder in event_cumode in the Irssi SILC
3565 client. Affected file irssi/src/silc/core/silc-channels.c.
3567 * Fixed the CUMODE_CHANGE notify handling in the server when
3568 server and router are announcing their clients on channels.
3569 Now the mode changes are saved and notified correctly. The
3570 affected file is /silcd/packet_receive.c.
3572 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3573 They really did not replace the cache entry in the ID Cache.
3574 Now they do that. Affected file silcd/idlist.c.
3576 * Fixed the KICK notify handling in the Irssi SILC client to
3577 update the channel records so that the kicked client does not
3578 appear to be on the channel. The affected file is
3579 irssi/src/silc/core/silc-channels.c.
3581 * Always update the conn->current_channel when executing command
3582 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3584 * Fixed the KILL notify handling in Irssi SILC client to remove
3585 the killed client on all channels.
3587 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3589 * Fixed the silc_parse_command_line to remove extra spaces
3590 from the start and end of the arguments. Affected file is
3591 lib/silcutil/silcutil.c.
3593 * Cancel and free any active protocol in the function
3594 silc_server_close_connection. Affected file silcd/server.c.
3596 * Cancel and free any active protocol in the function
3597 silc_client_close_connction. Affected file is
3598 lib/silcclient/client.c.
3600 * Do not execute the KILL command for clients that are in
3601 history (ie. they are not in the network). Affected file is
3604 * Fixed KILL notify handling, client does not crash anymore.
3605 Affected file irssi/src/silc/core/silc-channels.c.
3607 * Reduced the default packet buffer size from 2048 to 1024 in
3608 lib/silccore/silcpacket.c.
3610 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3611 counter to the SKE context that is incresed when the SKE library
3612 performs async operation outside the library. If the outside
3613 process frees the SKE context and FREED status will be set
3614 and the library will detect after the sync operation that the
3615 libary is freed. The affected files are
3616 lib/silcske/silcske[_status].[ch].
3618 * Resolve the client entry information in the function
3619 silc_client_channel_message to assure that NULL pointer is not
3620 passed as client entry to the application. */
3622 * Fixed the task timeout calculation to assure that there is
3623 never negative timeouts. The affected file is
3624 lib/silcutil/silcschedule.c.
3626 * Fixed the channel user mode notification sending in server.
3627 It was sent point-to-point to the router (or to server by router)
3628 but it needs to be destined to a channel. The routines now
3629 supports sending the channel user mode notifys to the channels
3630 when announcing clients and channels. Affected files are
3631 silcd/server.c and silcd/packet_receive.c.
3633 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3634 It did not actually replace the old channel entry in the cache.
3635 Affected file lib/silcclient/client_notify.c.
3637 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Fixed a possible crash in silc_packet_send_prepare. It now
3640 assures always that there is enough space in the buffer and
3641 at the tail area of the buffer (for MAC).
3643 Fixed the inbound buffer reallocation in silc_packet_read.
3644 It was old code and did not handle the reallocation correctly.
3647 The affected file is lib/silccore/silcpacket.c.
3649 * Fixed buffer overflow in silc_parse_nickname in the file
3650 lib/silcutil/silcutil.c.
3652 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * make install generates new server keys only if there is not
3657 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3660 Added check that if the NOREPLY is set then we will not send
3661 the away message. This avoids infinite loop of away messages
3662 if both clients are away. The affected file is
3663 lib/silcclient/client_prvmsg.c.
3665 * Fixed client crash if /NICK was given without arguments.
3666 Affected file lib/silcclient/command.c.
3668 * Server does not send the invite list in INVITE command back
3669 to the client if the list was not altered. Added this notion
3670 to the protocol spec as well. Affected file silcd/command.c.
3672 Fixed possible crash in INVITE command by checking the
3673 value of silc_server_get_client_route command.
3675 * Fixed the INVITE notify type handling. The arguments are now
3676 taken in correct order and client does not crash. The affected
3677 file is irssi/src/silc/core/silc-channels.c.
3679 Removed the "Inviting xxx to channel" message from the
3680 client library away and let the application handle it.
3681 Affected file lib/silcclient/command.c. Added that message
3682 to Irssi SILC client's message formats.
3684 * Fixed CMODE command crash in client. It now checks the
3685 amount of arguments correctly and does not crash. The affected
3686 file is lib/silcclient/command.c.
3688 * Do not create new channel automatically in silc_channels_join
3689 but check whether the channel by that name already exists.
3690 Affected file irssi/silc/core/silc-channels.c.
3692 * Do not send the SERVER_SIGNOFF to router if the disconnected
3693 entity was the router. Affected file silcd/server.c.
3695 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3696 SILC client as it was missing from there.
3698 Added the handling of the KICK notify to the Irssi SILC client
3699 as it was missing. Added "you have been kicked" message to
3700 Irssi SILC client's message modules formats.
3702 Added the handing of the KILL notify to the Irssi SILC client
3703 as it was missing. Added the kill message module formats
3706 The affected file is irssi/src/silc/core/silc-channels.c.
3708 * The router did not save the channel mode the server announced.
3709 Affected file silcd/packet_receive.c.
3711 * Fixed a possible crash in INFO command in server. If the
3712 server did not provide the server info it crashed. Affected
3713 file silcd/command.c.
3715 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Fixed the GETKEY command in the server to check also the
3718 global list. Otherwise the GETKEY would not work correctly
3719 in normal SILC server. Affected file silcd/command.c.
3721 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Fixed GETKEY crash, it crashed if the command did not succseed.
3725 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3728 is now real and not just an macro interface to GMP.
3730 Removed the entire GMP from the source tree and imported new
3731 NSS MPI library instead. Reason for removing GMP is that it is
3732 extremely large and compiles extremely slow. The NSS MPI
3733 is only a few files and compiles in less than 10 seconds.
3734 The speed is also about the same as GMP. The MPI is imported
3735 to lib/silcmath/mpi.
3737 If the system has GMP installed we will still use the GMP.
3738 If it is not then the NSS MPI will be compiled.
3740 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Merged a long nickname (127 characters long) crash bugfix from
3743 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3745 * Merged a freed memory reference bugfix from Irssi CVS tree.
3746 Affected file irssi/src/core/commands.c.
3748 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Added the server's public key sving and verification to the
3751 server when performing the SKE. This was missing and the
3752 remote server's (or router's) public key was accepted without
3753 checking whether we have it previously or trust it at all.
3754 Affected file silcd/protocol.c.
3756 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Check in the silc_server_timeout_remote if protocol is active
3759 and make sure that the protocol's final callback is called so
3760 that all memory if freed. Affected file silcd/server.c.
3762 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * silc_server_whois_send_reply crashed the server if the nickname
3765 was 127 characters long. Affected file silcd/command.c.
3767 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Added sanity check to the silc_server_new_client. If the hostname
3770 is provided inside username then check that the provided hostname
3771 really is the same as the resolved one. If the hostname was not
3772 resolved then check it from the public key. Affected file is
3773 silcd/packet_receive.c.
3775 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3776 if the server disconnected us and the connection is not valid
3777 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3779 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3780 the library to the lib/silcutil/silcutil.[ch].
3782 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Close log file after open. Affected file
3785 lib/silcutil/silclog.c.
3787 * Check whether sock == NULL in silc_client_send_packet and return
3788 if it is. Affected file lib/silcclient/silcclient.c.
3790 * Check rec->entry == NULL in the Irssi SILC Client before
3791 sending the channel message. Affecte file is
3792 irssi/src/silc/core/silc-servers.c.
3794 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Merged a splitted window bugfix from Irssi CVS tree. The
3797 affected file is irssi/src/fe-text/textbuffer-view.c.
3799 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3800 It did not print nickname.
3802 * Improved the distributions system a bit.
3804 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3807 irssi/src/fe-text/gui-window.c.
3809 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3810 to in-active server. The affected file is
3811 irssi/src/silc/core/client_ops.c.
3813 * Resolve the client in USERS command reply if the entry does
3814 not have username resolved. The affected file is
3815 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3816 command to WHOIS command to really resolve stuff. The USERS
3817 is not used any more in any critical section so WHOIS can
3818 be used even though it might be slower than IDENTIFY.
3820 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3823 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Changed the protocol API a bit more consistent in the
3826 lib/silccore/silcprotocol.[ch].
3828 * Changed the following headers to ROBODoc format:
3830 lib/silccore/silcpayload.h
3831 lib/silccore/silcprotocol.h
3832 lib/silccore/silcsockconn.h
3834 All core library headers are now formatted.
3836 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * Fixed a bug in Irssi SILC client; do not show that you are
3839 server/router operator if you really are not. Affected file is
3840 irssi/src/silc/core/client_ops.c.
3842 * Renamed silc_command_free_payload to silc_command_payload_free.
3843 Affected file lib/silccore/silccommand.h
3845 * Added silcmath.h to include the prototoypes of various routines
3846 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3849 * Changed the following headers to ROBODoc format:
3851 lib/silccore/silcchannel.h
3852 lib/silccore/silccommand.h
3853 lib/silccore/silcid.h
3854 lib/silccore/silcidcache.h
3855 lib/silccore/silcmode.h
3856 lib/silccore/silcnotify.h
3857 lib/silccore/silcpacket.h
3858 lib/silcmath/silcmath.h
3860 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Added checking to the server code not to start the server if
3863 ciphers and stuff are not configured properly. Affected files
3864 silcd/serverconfig.[h] and silcd/server.c.
3866 * Changed the layout of the header files of the public interfaces
3867 in the SILC libraries. The new layout supports ROBODoc
3868 documentation tool (and some others) so that it is easy to create
3869 a library reference manual. All the other headers and source
3870 code must still follow the CodingStyle document. Also source
3871 code must not include these ROBODoc stuffs, only the headers.
3872 Furthermore, all public interface headers must now be named
3873 by using `silc' prefix, example: silcapi.h, silccipher.h.
3874 Some files were renamed due to this. All the other headers
3875 must not be used as public interfaces. I will update the
3876 CodingStyle document later. Changed following headers, so far:
3878 lib/silcclient/silcapi.h
3879 lib/silccore/silcauth.h
3880 lib/silccore/silcprivate.h
3881 lib/silccrypt/silcdh.h
3883 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Removed silc_client_packet_send_flush from the client library
3888 as it is not needed. Affected file lib/silcclient/client.[ch].
3890 * Added printing of message of unresolved authentication method
3891 to the Irssi SILC client. Added it to the module formats.
3892 Removed the same message from the client library.
3894 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Added new distribution feature, DISTLABEL. Every distribution
3897 can define own preprocessor label that can be used in the
3898 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3899 file distributions, acconfig.h.pre and prepare.
3901 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Added Makefile.defines_int to include the actual definitions
3904 for Makefile.defines.in. Tested the new distribution system,
3905 created distributions and tested installation.
3907 * Added AWAY message printing to the Irssi SILC client. Added
3908 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3910 * Added SCONNECT command to call the SILC's CONNECT command.
3911 Cannot use CONNECT directly since Irssi uses that internally.
3912 Affected file irssi/src/silc/core/silc-servers.c.
3914 Added ACTION local command. It is same as ME command but takes
3915 the channel as mandatory argument.
3917 Rewrote some of the Irssi's help files to suite for SILC
3920 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Added Makefile.defines[.in] that should for now on be included
3923 in all Makefile.am file in the source tree. That file includes
3924 all common compilation definitions for SILC source tree.
3926 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Minor changes to the ./prepare script to change the package
3929 name according the distribution name to the configure.in.
3931 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Created new distribution system. Added file `distributions'
3934 that defines all the distributions that can be created out of
3935 the SILC source tree. The ./prepare script now reads that
3936 file to determine how to prepare the distributions. The
3937 first argument to the ./prepare is the name of the distribution
3938 and second is the version of the distribution. If given
3939 without arguments it creates the default (toolkit) distribution
3940 with the default version (defined in ./prepare).
3942 All Makefile.am files that are subject to the distributions
3943 are now named as Makefile.am.pre. These are ./Makefile.am
3944 and lib/Makefile.am. Others may be changed later.
3946 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added invite list, ban list, some key management and connection
3949 error message printing to module formats in the Irssi SILC client.
3951 * Added new silc_client_set_away_message to set the away message
3952 that is back to the person who sent private message. The
3953 affected file lib/silcclient/silcapi.h and the
3954 lib/silcclient/client_prvmsg.c.
3956 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Fixed the private message sending in the Irssi SILC client,
3959 added local command KEY to the Irssi SILC client.
3961 Added key management and key agreement message formats to the
3962 irssi/src/fe-common/silc/module-formats.[ch].
3964 Added USERS (alias WHO) printing, server/router operator
3965 indication and LIST command printing to the module formats.
3967 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3969 * Fixed channel joining notify handling, cumode notify handling
3970 from Irssi SILC client.
3972 * Added SILC specific module-formats to the Irssi SILC client so
3973 that SILC specific message hilighting, colors etc is possible.
3974 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3976 Added channel mode, channel user mode, actions, notices,
3977 whois and whowas printing to the the module-formats.c.
3979 * Fixed a bug in channel deletion in the server. The channel
3980 is not left to the cache even if the channel founder auth mode
3981 is set when there are no users anymore on the channel. Affected
3982 file silcd/server.c.
3984 * The silc_net_localhost now resolves the entire hostname including
3985 the domain name. Affected file lib/silcutil/silcnet.c.
3987 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3989 * Changed the ask_passphrase client operation to be ascynchronous.
3990 It has now a completion callback and a context that the
3991 application must call after it has got the passphrase from
3992 the user. Affected files lib/silcclient/silcapi.h,
3993 lib/silcclient/protocol.c, lib/silcclient/command.c and
3996 Added SilcAskPassphrase callback that the application calls
3997 to deliver the passphrase to the library.
3999 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4000 The public key verification and especially a certificate
4001 verification is asynchronous procedure.
4003 Added new SILC_SKE_STATUS_PENDING status to indicate the
4004 request is pending and a callback will be called to finalize
4007 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4008 indicate that remote end did not send its public key (or
4009 certificate), even though we require it. Added check for this
4010 condition in the SKE. This was a security bug, now fixed.
4012 Defined new SilcSKEVerifyCbCompletion callback that is called
4013 when the verification process is completed.
4015 The affected files lib/silcske/silcske_status.h and
4016 lib/silcske/silcske.[ch].
4018 * Changed the verify_public_key client operation to be async
4019 as well. Defined SilcVerifyPublicKey callback that is used to
4020 indicate the success of the public key verification process.
4022 Changed the server and client to use the new async client
4025 * Changed the Irssi SILC client's internal scheduler to be called
4026 twice as many times as it used to be. As a result the client
4027 should be a bit faster now. Affected file is
4028 irssi/src/silc/core/silc-core.c.
4030 * Added support to Irssi SILC client of asynchronous public key
4031 verification and passphrase inquiry. Affected file is
4032 irssi/src/silc/core/silc-core.c.
4034 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Do not say "You have left channel %s" in client library.
4037 Moved it to the application. Affected files are
4038 lib/silcclient/command.c and silc/client_ops.c.
4040 * Fixed silc_client_get_clients. Command context was not
4041 duplicated and was freed memory in the callback. Affected
4042 file lib/silcclient/idlist.c.
4044 * Do not say "you are now talking..." on JOIN command in the
4045 client library. The appliation must handle it.
4047 * Do not say ".. changed topic to" in command reply in the
4048 client libary. The application must handle it.
4050 * Fixed TOPIC command sending in the client library.
4052 * Fixed a memory leak in silc_client_command_free in the file
4053 lib/silcclient/command.c.
4055 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Imported a modified version of Irssi client to the source tree.
4058 The Irssi will be used to create a new client called
4059 Irssi SILC. Imported to irssi/.
4061 Added silc_core_init_finish function to the Irssi. Affected
4062 file irssi/configure.in.
4064 A lot changes in the Makefile.ams around the irssi tree.
4066 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Do not rehash if the new size is same as the old size of the
4069 hash table, in the silc_hash_table_rehash*. The affected file
4070 lib/silcutil/silchashtable.c.
4072 * Replaced hash_table_del_by_context calls from the server
4073 (when channel->user_list and client->channels) to the
4074 hash_table_del as it is sufficient and faster.
4076 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Added silc_hash_table_list, silc_hash_table_get and the
4079 SilcHashTableList structure to provide an alternative way to
4080 traverse the hash table. The affected files are
4081 lib/silcutil/silchashtable.[ch].
4083 * Changed the server's idlist routines to use the hash table
4084 routines to optimize the code.
4086 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Replaced the client entry's `channel' list and channel entry's
4089 `user_list' list to hash tables for optimized lookup. Changed
4090 the code to use the hash table interface around the code.
4091 Affected file lib/silcd/idlist.[ch].
4093 * Added `auto_rehash' boolean argument to the function
4094 silc_hash_table_alloc to indicate whether the hash table should
4095 auto-rehash when it thinks is appropriate time. It will
4096 increase the hash table size if the there is twice as much
4097 entries in the table than the size of the table, and will
4098 decrease the size if there are twice as less entries than
4099 the size of the table.
4101 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4105 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * silc_idcache_purge_by_context deletes the entry now by context
4108 as it is supposed to do. Affected file lib/silccore/idcache.c.
4110 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4111 client is not anymore valid (WHOWAS givens the info) and not
4112 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4114 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Removed the `data' and `data_len' arguments from the ID Cache
4117 interfaces and added `name' argument. ID Cache does not handle
4118 anymore the binary data only a names associated with given ID.
4120 * When hashing a Client ID with silc_hash_id the entire ID is
4121 not hashed anymore, instead only the hash of the Client ID is
4122 hashed. This way we can access the Client ID from the cache
4123 with Client ID but with the hash of the ID (which is a hash of
4124 the nickname) as well without any difference in performance.
4126 Added also silc_idcache_find_by_id_one_ext to do one on one
4127 searching when we have the actual ID. Added also function
4128 silc_hash_client_id_compare. The affected files are
4129 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4131 * When hashing the name associated with a ID it is always done
4132 in lowercase. This way we can access the cache without worrying
4133 about case-sensitivity, even though, for example nicknames are
4136 * Fixed a bug in server with channel message sending. It put
4137 wrong ID type as destination ID. The affected file
4138 silcd/packet_send.c.
4140 * silc_idcache_del_by_context now deletes from all hash tables
4141 by context. Affected file lib/silccore/idcache.c.
4143 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Changed the client library to use the new ID Cache interface.
4146 Changes around the source tree.
4148 * Added silc_hash_table_rehash_ext to rehash with specific
4149 hash function. Affected file lib/silcutil/silchashtable.[ch].
4151 * Added silc_hash_string_compare to compare two strings in the
4152 hash table. Affected file lib/silcutil/silcutil.[ch].
4154 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Added new function silc_idcache_del_by_context into the
4157 lib/silccore/idcache.[ch].
4159 * Changed the server's ID list routines to use the new ID Cache
4160 interface. Changes around the source tree.
4162 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Added silc_hash_table_del[_by_context]_ext functions in to the
4165 lib/silcutil/silchashtable.[ch].
4167 Removed silc_hash_table_find_all* routines and added new
4168 silc_hash_table_find_foreach to replace them.
4170 Added silc_hash_table_replace_ext function as extended
4171 replacing function. Separated the simple hash table interface
4172 from the extended hash table interface in the file
4173 lib/silcutil/silchashtable.h.
4175 * Fixed minor bugs and changed it to use some of the new
4176 hash table functions in lib/silccore/idcache.c
4178 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added new function silc_hash_table_find_all to return all keys
4181 in the hash table by the specified key. As the hash table is
4182 collision resistant it also makes it possible to have several
4183 duplicate keys in the hash table. This function may be used to
4184 find all of the keys from the hash.
4186 Added user_context arguments to the SilcHashFunction,
4187 SilcHashCompare and SilcHashDestructor to deliver user specified
4190 Added new fuctions silc_hash_table_find[_all]_ext to do
4191 extended lookup with specified hash and compare functions and
4192 specified user contexts.
4194 Added new function silc_hash_table_add_ext to add the key
4195 with specified hash function and user context.
4197 Added new function silc_hash_table_foreach to traverse all
4198 entrys in the hash table. Added SilcHashForeach callback
4201 Added new function silc_hash_table_del_by_context to delete
4202 the entry only if the context associated with the key matches.
4204 Affected files are lib/silcutil/silchashtable.[ch].
4206 * Removed silc_hash_[server/client/channel]_id and added just
4207 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4208 silc_hash_id_compare to compare two ID's using as the hash table
4209 comparison function. Added also silc_hash_data to hash
4210 binary data and silc_hash_data_compare to compare it.
4212 * Removed silc_idlist_find_client_by_hash as it is not needed
4213 anymore. Affected file silcd/idlist.[ch].
4215 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4216 to use internally the SilcHashTable. The new ID Cache is a lot
4217 faster than the old one. Some of the ID Cache interface was also
4218 rewritten and obsolete and stupid functions were removed.
4220 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Added entry_count field to the SilcHashTable to keep the number
4223 of the entries in the table. Implemented the function
4224 silc_hash_table_rehash. Added new function
4225 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4227 Fixed a minor bug in silc_hash_table_free.
4229 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4230 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4231 into the lib/silcutil/silcutil.[ch].
4233 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Implemented a collision resistant hash table into the
4236 lib/silcutil/silchashtable[ch]. See the header and the source
4237 for the SilcHashTable API.
4239 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Merged dotconf version 1.0.2 into lib/dotconf.
4243 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Do not compile anything in lib/silcsim/* if the SIM support
4246 is not enabled. The tree should now compile without problems
4249 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Compiled the SILC under cygwin. Compiled and tested briefly
4252 without problems. More tests needed. The SIMs didn't compile
4255 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4257 * Fixed possible crash in silc_get_username in the
4258 lib/silcutil/silcutil.c.
4260 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Fixed a va_arg in silc/client_ops.c.
4264 * Oops, RC5 routines were named AES and caused some problems
4265 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4267 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Added new SilcIDIP structure into the lib/silccore/id.h and
4270 replaced the old `ip' fields from all SILC ID's to that type.
4271 This is a step towards IPv6 support.
4273 The silc_id_get_len takes now the ID as an extra argument.
4274 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4275 both IPv4 and IPv6 based ID's.
4277 The affected files are lib/silccore/id.[ch] and other files
4278 around the tree using these routines.
4280 * Removed the ID length arguments in server from various
4281 silc_server_send_notify_* routines -> they are not needed
4284 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Fixed memory leak in silc_encode_pem_file in the file
4287 lib/silcutil/silcutil.c.
4289 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Check minor version as well in the SKE. Affected files are
4292 silcd/protocol.c and lib/silcclient/protocol.c.
4294 * Added --identifier option to the server so that an identifier
4295 can be when creating the public key for the server. Affected
4296 file is silcd/silcd.c.
4298 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4299 lib/silccrypt/silcpkcs.c.
4301 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Register default ciphers and stuff when using -C option with
4304 the server. Affected file sildc/silcd.c.
4306 * Put back the servers public key filename format, it is better
4307 than the new one. For now, the client keys are saved with the
4308 new filename format. The affected file silc/client_ops.c.
4310 * Implemented the Cipher API for the rest of the ciphers that
4311 did not implement it or implemented it the wrong way.
4313 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4315 * Register default ciphers and stuff when using the -S option
4316 in the client. Affected file silc/silc.c. Same also when
4317 creating new key pair with -C option.
4319 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Fixed the silc_verify_public_key client operation function to
4322 save the public keys differently. The fingerprint is now
4323 used as filename and not the hostname. This way also the
4324 client keys are saved uniquely and not with hostnames. The
4325 affected file is silc/client_ops.c.
4327 * Trimmed the silc_hash_fingerprint function to remove extra
4328 whitespaces from the end of the fingerprint. The affected
4329 file is lib/silccrypt/silchash.c.
4333 * Added silc_cipher_register_default function to register all
4334 default ciphers. It can be used when configuration files
4335 does not exist and the application does not want any specific
4336 ciphers in any specific order.
4338 The SilcDList is now used as silc_cipher_list dynamically
4339 allocated cipher list. Removed the static list all together
4340 and now all ciphers must be allocated to the dynamic list.
4341 The silc_cipher_alloc routine was changed to check only the
4344 All silc_cipher_* routines that used to return int returns
4347 The affected files lib/silccrypt/silccrypt.[ch].
4349 * The same thing was done to silc_hash_* as for silc_cipher_*
4350 routines. Affected files lib/silccrypt/silchash.[ch].
4352 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4353 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4354 Added also silc_pkcs_[un]register[_default] functions.
4355 Removed the data_context from the PKCS API.
4357 * Added silc_hmac_register_default function to register default
4358 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4359 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4360 to unregister all hmacs at once.
4362 * Register the default ciphers, hash functions, PKCSs and HMACs
4363 if client's configuration file does not exist. The affected
4366 * The client did not load the hash functions from the SIM
4367 modules at all. Added support for this. Affected file is
4368 silc/clientconfig.c.
4370 * When decoding public key with silc_pkcs_public_key_decode, check
4371 the supported algorithm only if PKCS are registered. Affected
4372 file lib/silccrypt/silcpkcs.c. The same was done with the
4373 silc_pkcs_private_key_decode.
4375 * Fixed the SILC List routines to keep the list always in order.
4376 It used to change the list's order when traversing the list but
4377 not it preserves the order. Affected file lib/trq/silclist.h.
4379 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Added the client library to use the SilcSocketConnection's
4382 reference counter (by silc_socket_dup) to prevent the bug that
4383 the socket object may be freed underneath async operation.
4385 * The name resolv library checking fixes in the configure.in.pre.
4388 * Created new version of the protocol drafts for future
4389 development. The -03 drafts are the ones that will be changed
4390 in the trunk now and the -02 will remain as they are.
4392 * Send list of CUMODE notifys to the router when announcing
4393 the channel users to the router. Affected file silcd/server.c.
4394 If the router receiving channel founder CUMODE for a channel
4395 that already has channel founder it will send CUMODE notify
4396 to the sender to remove the channel founder rights from the
4397 announced client. Affected file silcd/packet_receive.c.
4399 * The CUMODE notify may now use Server ID as well as the entity
4400 who changes the mode. Updated protocool specs.
4402 * Updated INSTALL and README files.
4404 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * New web pages in the http://silc.pspt.fi. The pages was
4411 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Implemented the [DenyConnectin] config section in the server.
4414 Added silc_server_config_denied_conn to check whether incoming
4415 connection is denied. Affected file silcd/serverconfig.[ch].
4417 * Do not check the ports when checking the incoming configuration
4418 data if the port is 0, meaning any. Affected file is
4419 silcd/serverconfig.c.
4421 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Fixed buffer overflow in silc_string_compare in the file
4424 lib/silcutil/silcutil.c.
4426 * Fixed double free in silc_server_command_leave in the file
4429 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Fixed the version checking in the server. Affected file is
4434 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4436 * Fixed the configuration data fetching when accepting new
4437 connections in the server. Affected file silcd/server.c.
4439 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Added `sender_entry' argument to the function
4442 silc_server_packet_relay_to_channel so that we can check
4443 whether some destination actually belongs to the same route
4444 the sender belongs (ie, we must not resend the packet to the
4445 sender). Affected file silcd/packet_send.[ch].
4447 * Added `servername' field to the SilcClientEntry in the server
4448 to hold the name of the server where client is from. Affected
4449 file is silcd/idlist.h.
4451 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Moved the channel message encrypting in the router betwen
4454 router connections from silc_server_channel_message to the
4455 silc_server_packet_relay_to_channel since we want to check
4456 whether we have anybody channel before encrypting anything.
4457 Affected files silcd/packet_[receive/send].c.
4459 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Fixed the [AdminConnection] server config section to support
4462 multiple entries. Affected file silcd/serverconfig.c.
4464 * Added support into the server to check the validity of the
4465 incoming connection before executing any KE or authentication
4468 * The connection configuration is now saved to the KE and
4469 connection auth protocol contexts and not fetched anymore in
4470 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4472 * The local hosts listenning address and port is also resolved
4473 now when starting the server. We want to have the socket object
4474 to include the real address and port for the listener. Added
4475 new function silc_net_check_local_by_sock into the files
4476 lib/silcutil/silcnet.[ch].
4478 * Fixed a broadcast bug in server -> do not broadcast if we
4481 * Fixed a routing bug. Do not route broadcast packets ever.
4482 Broadcast packets must be processed always and not routed since
4483 they may be destined to some other host than yourself and thus
4484 would get routed without no good reason. Affected file is
4487 * Added function silc_server_config_is_primary_route to check
4488 whether primary router connection has been configured (a router
4489 configuration that we are initiating). If there is not, we
4490 will assume that there is only two routers in the SILC network
4491 and we will use the incoming router connection as our primary
4492 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4494 * Changed the order of the broadcasting. Broadcast _after_ the
4495 packet has been processed not before. Affected file is
4498 * Fixed a [ClientConnection] parsing bug. The port was never
4499 parsed correctly thus resulting to port 0. Affected file
4500 silcd/serverconfig.c.
4502 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4503 argument and did not set the broadcast packet flag. Affected
4504 file silcd/packet_send.c. Fixed same bug in the function
4505 silc_server_send_notify as well.
4507 * If we receive NEW_ID packet for our own ID in the server, ignore
4510 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Removed the nickname from the Private Message Payload.
4515 Updated the code and the protocol specs.
4517 * Updated protocol specs for submitting to the IETF.
4519 * Tweaked the Random Number Generator a bit. Affected file
4520 lib/silccrypt/silcrng.c. Exported a new function
4521 silc_rng_[global]_add_noise which can be used to add more
4524 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4526 * Do not parse packets with different timeout when protocol
4527 is active -> may cause problem with rekey. Affected file
4530 * When server receives signoff notify it must not create
4531 new channel key if the client is on any channels since the
4532 sender of the signoff notify will create it.
4534 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Added printing of error messages during SKE protocol from the
4537 failure packet sent by server during SKE. Affected file
4540 * Removed the client's failure_callback handling with timeout
4541 and handle it immediately when received.
4543 * The SKE library returned wrong type in SUCCESS and FAILURE
4544 packets. They must be 32 bit MSB not 16 bit MSB.
4546 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Ok, rewrote the logic of the re-key and now it seems to work.
4549 I tested it on high traffic with frequent re-keys without
4550 problems. Added hmac_receive (and renamed hmac to hmac_send)
4551 in SilcClientConnection in lib/silcclient/client.h and
4552 in SilcIDListData in silcd/idlist.h. Also, removed the
4553 SilcPacketParserContext's cipher and hmac fields as they are
4554 not needed anymore and actually caused some problems when
4555 the ciphers and hmac's changed underneath the packet parser.
4557 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * If re-key protocol is active then process the incoming packets
4560 synchronously since we must assure that icoming packets encrypted
4561 with the old key is processed before the new keys is set to
4562 use. This is true other packets than for REKEY packets.
4563 Affected file silcd/server.c. The same was done to client library
4564 as well, affected file lib/silcclient/client.c.
4566 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Fixed bug in client and server to accept the force send if
4569 the packet is send from silc_[server/client]_packet_process
4570 function. Otherwise the packets are never delivered, oops.
4572 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Disable force sending of packets when REKEY protocol is active.
4575 We must assure that no packet is sent directly when rekey is
4576 performed. All packets must be sent through packet queue.
4577 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4578 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4579 function is silc_[server/client]_packet_send_real to check
4582 * Replaced the SIM paths from example config files to
4583 /usr/local/modules. Also, make install creates now
4584 /usr/local/silc/logs directory to hold all the SILC server
4587 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Made the configure.in.pre work on Solaris. Patch by salo.
4591 * Made all ciphers compatible with non-x86 machines. Defined
4592 CBC mode macros into lib/silccrypt/ciphers_def.h.
4594 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Fixed the make install.
4598 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * When MAC computation fails the silc_packet_decrypt returned 0
4601 even though it was supposed to return -1. Fixed this. The
4602 affected file is lib/silccore/silcpacket.c.
4604 * Do not replace the config files in /etc/silc (in make install)
4605 if they already exist. Affected file ./Makefile.am.
4607 * Do not send re-key packets immediately but through packet queue.
4608 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4610 * Changed silc_net_check_host_by_sock to return FALSE if the
4611 IP/DNS could not be resolved. Though, it returns the IP address
4612 now even if it could not resolve it (but returns also FALSE).
4613 Affected file lib/silcutil/silcnet.[ch].
4615 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Added silc_pkcs_decode_identifier to decode the public key's
4618 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4619 Added also silc_pkcs_free_identifier. Added also new context
4620 SilcPublicKeyIdentifier.
4622 * Added -S option to the silc client. It is used to dump the
4623 contents of the specified public key file.
4625 * Changed the PKCS api to return the public key length when
4626 setting the public key.
4628 * Fixed a fatal bug in the public and private key file loading.
4629 Affected file lib/silccrypt/silcpkcs.c.
4631 * Execute the packet parsing for client with zero (0) timeout
4632 if the protocol is active. Affected file silcd/server.c.
4634 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Made the key generation options to the silcd program. Added
4637 -C option, equivalent to client's option.
4639 * Added new [ServerKeys] config section to the server. It
4640 configures the server's public and private key.
4642 * Defined generic Public Key Payload into the protocol
4643 specification to send specific type of public keys and
4646 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4647 public key or certificate.
4649 * Implemented the GETKEY command to the server and to the
4650 client library and on user interface.
4652 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Made preliminary `make install' work.
4656 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Added SilcServerRekey context into silcd/idlist.h.
4660 * Added the PFS support as defined in the specification to the
4661 SKE protocol. Affected files lib/silcske/*.c.
4663 * Added `ske_group' field to the SilcServerRekey context to hold
4664 the number of the SKE group that is used with PFS in re-key.
4665 Affected file silcd/idlist.h.
4667 * Added PFS re-key support to the server. Affected file is
4670 * Added silc_protocol_cancel to cancel execution of the next
4671 state of the protocol. Affected file is
4672 lib/silccore/silcprotocol.[ch].
4674 * Added the re-key support with and without PFS to the client
4675 library. Re-key is performed once in an hour, by default.
4677 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4678 Added silc_client_rekey_callback and silc_client_rekey_final.
4679 Affected files are lib/silcclient/protocol.[ch] and

4682 * Removed the `hmac_key' and `hmac_key_len' fields from the
4683 SilcClientConnection structure; not needed. Affected file is
4684 lib/silcclient/client.h.
4688 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Do not ask whether user wants to use the negotiated private key
4691 for private messages, just use it. Affected file is
4692 silc/local_command.c.
4694 * Added `send_enc_key' and `enc_key_len' fields to the
4695 SilcIDListData structure since they are needed in the re-key
4696 phase. Affected file is silcd/idlist.[ch].
4698 * Implemented the simple re-key protocol into the server.
4699 Affected files silcd/server.c and silcd/protocol.[ch]. The
4700 re-key will be performed once in an hour, by default.

4707 and the specifications.
4709 * Adde `pfs' field to the SilcIDListData to indicate whether
4710 the PFS is to be performed in the re-key. Affected file is
4713 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4716 int64 of at least the xintXX size. If void * is less that 4
4717 bytes uint32 * will be used. Defined bool as boolean.
4719 * Changed _ALL_ unsigned long and unsigned int to uint32,
4720 unsgined short to uint16 in the source tree.
4722 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4723 not handle clients that has entry->data.registered == FALSE.
4724 They are not in the network anymore. Affected file is
4727 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Implemented the sending of the SERVER_SIGNOFF notify in the
4730 server. Affected file is silcd/server.c.
4732 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4733 Added also silc_notify_payload_encode_args into the
4734 lib/silccore/silcnotify.[ch].
4736 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4737 Affected file silcd/packet_receive.c.
4739 * Implemented the SERVER_SIGNOFF notify handling in the client
4740 library. Affected file lib/silcclient/client_notify.c. Also,
4741 implemnted the printing of the SERVER_SIGNOFF info to the
4742 application. Affected file silc/client_ops.c.
4744 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4745 if the deleting was successful. Affected file silcd/idlist.[ch].
4747 * Added support for public key authentication in the connection
4748 authentication protocol in the client library. Affected file
4749 lib/silcclient/protocol.c.
4751 * Changed the server's silc_idlist_get_clients_by_* interface
4752 to support already allocated array so that new entries may be
4753 added to pre-allocated array. Affected file silcd/idlist.[ch].
4754 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4755 and command replies.
4757 * All command reply functions in the server now calls the
4758 pending command callback even if error occured. This way the
4759 error will be delivered to the client as well. Affected files
4760 silcd/command.c and silcd/command_reply.c.
4762 * Fixed INFO command to return local server's info if no server
4763 was provided. Affected file lib/silcclient/command.c.
4765 * Removed RESTART command for good. Updated the code and the
4768 * Rewrote parts of the task system. It is a bit simpler now.
4769 Removed unsued task priorities. The affected files are
4770 lib/silcutil/silctask.[ch].
4772 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Moved the USERS printing from the library to the application.
4775 Affected files lib/silcclient/command.c and silc/client_ops.c.
4777 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Added channel key re-key support. The re-key is perfomed
4782 only by the router and is done once in an hour. Added `rekey'
4783 field to the SilcChannelEntry in the server. Affected files
4784 silcd/server.c and silcd/idlist.h.
4786 * Added silc_task_unregister_by_context into the file
4787 lib/silcutil/silctask.[ch].
4789 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Added SILC_UMODE_GONE mode to indicate when the client is not
4792 present in the SILC network. Added also support to the local
4793 command AWAY that will set this mode. Added support of showing
4794 "xxx is gone" in WHOIS command. The USERS command shows the
4795 gone status as well.
4797 * Fixed setting server and router operator privileges in the
4798 server's UMODE command. Affected file silcd/command.c.
4800 * Merged the SKE KE1 and KE2 payloads into one payload. The
4801 new KE payload is equivalent to the old KE2 payload.
4803 Cleaned up the SKE Start Payload parsing. It now uses the
4804 simple buffer unformatting to do the parsing. A lot faster
4807 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4808 to the SKE that is used to indicate whether both of the SKE
4809 parties should perform authentication. By default only the
4810 responder performs authentication. By setting this flag also
4811 the initiator must do authentication. By default it is unset
4812 since in normal SKE case, client to server connection, only
4813 the responder should do authentication. When doing SKE between
4814 two clients both should perform authentication. Updated the
4815 code and the protocol specs.
4817 * A little fix to IDENTIFY command in the server. Search the
4818 client first by hash not nickname. Affected file is
4821 * Fixed the silc_client_close_connection to support closing
4822 the client to client connections wihtout deleting too much
4823 data. Affected file lib/silcclient/client.c.
4825 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4826 are received if protocol used to be active but is not anymore
4827 the application would crash due to NULL pointer dereference.
4828 Affected files silcd/server.c and lib/silcclient/client.c.
4830 * Added `hash' field to the SilcClientConnection to include
4831 the hash function negotiated in the SKE protocol.
4833 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4834 to set the channel founder authentication data. A client can
4835 claim the founder rights later by providing the authentication
4836 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4837 This way the channel founder can regain the channel founder
4838 privileges even it is left the channel. This works only on
4839 local server and the client must be connected to the same
4840 server to be able to regain the founder rights. Updated the
4841 protocol specs accordingly.
4843 Added support to the CMODE command in the client to set the
4844 founder auth data. Read the README to see how to set it.
4846 Added support to the CUMODE command to claim the founder
4847 rights. Read the README to see how to do it.
4849 Added support for the founder authentication to the Channel
4850 Entry in the server. Affected file silcd/idlist.h.
4852 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4853 server's CMODE command. Affected file silcd/command.c.
4855 * Added the following new functions into lib/silccore/silcauth.[ch]:
4856 silc_auth_get_method and silc_auth_get_data.
4858 * The server now saves the remote hosts public key to the
4859 SilcIDListData pointer. Affected file silcd/protocol.c.
4861 * The normal server now does not remove the channel entry from
4862 the cache if the founder authentication data is set. It used
4863 to remove it if the founder was the last one on the channel on
4864 the server and left the channel. The auth data is saved and
4865 if the channel is re-joined later the old entry is used with
4866 the old auth data. Affected files silcd/command_reply.c and
4869 * Removed the `pkcs' field from the SilcIDListData structure
4870 in the server; it is not used. Affected file silcd/idlist.h.
4872 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Fixed packet processing on slow links. Partial packets were
4875 never re-processed because the incoming data buffer was cleared
4876 by the application. Application must not directly clear the
4877 sock->inbuf, the packet processing routines handle it. Fixed
4878 this in client library and in server.
4880 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Fixed the WHOIS and IDENTIFY send reply function to really
4883 check whether to send list or just one entry. Affected file
4886 * Cleaned up the LEAVE command's channel key distribution. The
4887 affected file silcd/command.c.
4889 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4890 can enforce the channel mode as well. In that case the ID
4891 includes the ID of the server. The code now enforces the
4892 mode change if the router have different mode than the server.
4894 * The notify client operation with CMODE_CHANGE notify can now
4895 return NULL client_entry pointer if the CMODE was not changed
4896 by client. Application must check for this.
4898 * Added <Server ID> argument to INFO command to support server
4899 info fetching by Server ID.
4901 * Added silc_server_announce_get_channel_users to get assembled
4902 packets of channel users of the specified channel. Affected
4903 file silcd/server.[ch].
4905 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4906 was freed underneath the ID Cache.
4908 * Re-announce clients when the server received CHANNEL_CHANGE
4909 notify from the router. Affected file silcd/packet_send.c.
4911 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4914 crashed since it did not handle the fact that there is no cipher
4915 called "3" and didn't check the error condition. Now fixed.
4917 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4918 flag. It can be used to send message requests.
4920 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4922 * Implemented the RESTART command in the client.
4924 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4925 notice type messages. Added notice printing to the user
4928 * The channel keys are not re-generated if the channel's mode
4929 is PRIVKEY, ie private key on the channel exists. Affected
4930 files silcd/server.c and silcd/command.c.
4932 * Fixed a little bug in channel message delivery when channel
4933 private keys are set in the server. Affected file is
4934 silcd/packet_send.c.
4936 * Changed the setting on channel->on_channel = TRUE from the
4937 silc_client_save_channel_key to the JOIN command reply. The
4938 key payload is not received if the private channel key is set.
4939 Affected file lib/silcclient/command_reply.c and the
4940 lib/silcclient/client_channel.c.
4942 * When the CMODE_CHANGE notify is sent and the channel private
4943 key mode is removed the channel key must be re-generated in
4944 other cells as well. Added this support for the router in the
4945 silcd/packet_receive.c.
4947 * Added new local command NOTICE to send notice message on
4948 channel. Affected file silc/local_command.[ch].
4950 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Added new local command ME to the client. It is used to send
4953 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4954 some action. Affected file silc/local_command.[ch].
4956 * Changed channel_message and private_message client operations
4957 to deliver the message flags to the application. Added also
4958 the `flags' arguments to the silc_client_send_channel_message
4959 and silc_client_send_private_message functions. Affected file
4962 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Redefined the Private Message Payload to support private message
4965 keys and to support the new private message flags. Updated
4966 the protocol specs. Flags makes it possible to have for example
4967 CTCP style messages.
4969 * Added new type SilcPrivateMessagePayload and defined an API
4970 for it in the lib/silcclient/silcprivate.[ch].
4972 * Tested private message private keys successfully. Tested the
4973 private message key set, unset and list commands with the new
4976 * Redefined the Channel Message Payload to include the channel
4977 message flags (equal with private message flags) to support
4978 for example CTCP style messages.
4980 * Defined some of the message (for channel and private message)
4981 flags. Updated the protocol specs and added the flags to the
4982 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4984 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Added SilcKeyAgreementStatus type to the key agreement routines
4987 to indicate the current status and error if one occured.
4988 The status types are defined in the lib/silcclient/silcapi.h.
4990 * Added new local command KEY that is used to set and unset private
4991 keys for channels, set and unset private keys for private messages
4992 with remote clients and to send key agreement requests and
4993 negotiate the key agreement protocol with remote client. The
4994 key agreement is supported only to negotiate private message keys,
4995 it currently cannot be used to negotiate private keys for channels,
4996 as it is not convenient for that purpose.
4998 * Fixed a minor pending callback setting bug in the function
4999 silc_client_get_client_by_id_resolve, now the function works.
5000 Affected file lib/silcclient/idlist.c.
5002 * Added function silc_net_get_local_port to get local bound
5003 port by socket. Added to lib/silcutil/silcnet.[ch].
5005 * Added `sockets' and `sockets_count' fields to the SilcClient
5006 object. They hold the sockets of the listenning sockets in
5007 the client. Listenning sockets may be for example the key
5008 agreement server. Affected file lib/silcclient/client.[ch].
5009 Added functions the silc_client_add_socket and the
5010 silc_client_del_socket. They are exported to the application
5013 * Added ~./silc/clientkeys to support other client's public keys.
5015 * Renamed verify_server_key client operation to verify_public_key
5016 and added one argument to indicate the type of the connection
5017 (server, client etc.).
5019 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Added silc_server_connection_auth_request to handle the
5022 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5023 silcd/packet_receive.[ch].
5025 * Added silc_server_send_connection_auth_request into the
5026 silcd/packet_send.c to send the connection auth request packet.
5028 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5031 * Fixed the public key authentication in responder side in the
5032 server. The `auth_data' pointer includes the SilcPublicKey
5033 not the path to the public key. Affected file silcd/protocol.c.
5035 * Implemented the public key authentication in the initiator side
5036 in the server. Affected file silcd/protocol.c.
5038 * Removed the [RedirectClient] config section from the server
5039 configuration. Is not needed and I don't want to implement it.
5041 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Cleaned up the CMODE command in the server. It now works
5044 correctly and supports all the modes defined in the protocol.
5045 Affected file is silcd/command.c.
5047 * Added `hmac_name' field to the SilcChannelEntry in the server
5048 to hold the default HMAC of the channel. It can be set when
5049 creating the channel (with JOIN command). Affected files
5052 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5053 type to indicate the change of the current cipher and hmac
5054 on the channel. Client can safely ignore the <cipher> argument
5055 (if it chooses to do so) since the CHANNEL_KEY packet will
5056 force the channel key change anyway. The <hmac> argument is
5057 important since the client is responsible of setting the new
5058 HMAC and the hmac key into use.
5060 * Fixed the CMODE command in the client library as well.
5062 * Tested CMODE command in router environment successfully.
5064 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Show the version of the remote client (or server) when connecting
5067 to the server. It is logged to the log file. Affected file
5068 is silcd/protocol.c.
5070 * Fixed the KILLED notify handling in the client library. The
5071 client must be removed from all channels when receiving the
5074 Also, do not remove the client entry when giving the KILL
5075 command but when the KILLED notify is received.
5077 * Removed silc_idlist_find_client_by_nickname from the server.
5078 Not needed anymore. Affected files silcd/idlist.[ch].
5080 * Implemented the CHANNEL_CHANGE notify type handling to the
5081 server. Affected file silcd/server.c.
5085 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added silc_server_send_notify_invite to send the INVITE
5088 notify between routers.
5090 * Implemented the INVITE command correctly to the server.
5092 * Implemented the INVITE notify type handling in the server.
5094 * Implemented the INVITE command to the client library and on the
5097 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Added function silc_server_get_client_resolve to find the
5100 client entry by ID from all ID lists and then resolve it
5101 (using WHOIS) if it cannot be found. Affected file is
5104 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Implemented the BAN command to the client library.
5108 * The JOIN command in the server now checks the invite list
5111 * Changed the silc_command_reply_payload_encode_va and the
5112 silc_command_payload_encode_va to support that if argument is
5113 NULL it ignores and checks the next argument. Affected file
5114 lib/silccore/silccommand.c.
5116 * Added silc_server_send_notify_ban to send the BAN notify
5117 type between routers.
5119 * Chaned the silc_notify_payload_encode to support that if
5120 argument is NULL it ignores and checks the next argument.
5121 Affected file lib/silccore/silcnotify.c.
5123 * Tested ban lists in router environment successfully.
5125 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Implemented BAN command to the server, in silcd/command.[ch].
5129 * Removed the BAN and INVITE_LIST modes from the CMODE command
5132 * Added function silc_string_match to regex match two strings.
5133 Affected files lib/silcutil/silcutil.[ch].
5135 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Redefined parts of the SilcChannelEntry in the server to support
5138 the new ban and invite lists.
5140 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Redefined the INVITE command. The same command can be used to
5143 invite individuals to the channel but also to manage the invite
5144 list of the channel (to add to and remove from the invite list).
5145 Updated the protocol specs.
5147 * Added new command SILC_COMMAND_BAN that can be used to manage
5148 the ban list of the channel. Updated the protocol specs.
5150 * Removed the channel modes: the SILC_CMODE_BAN and the
5151 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5152 in the CMODE command. The equivalent features are now available
5153 using INVITE and BAN commands. Updated the protocol specs.
5155 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5156 in the network about change in the current ban list. The notify
5157 type is not used by the client.
5159 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5160 support the invite lists.
5162 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Added new function silc_string_regexify that converts string
5165 including wildcard characters into regex string that can
5166 be used by the GNU regex library. Added into the file
5167 lib/silcutil/silcutil.[ch].
5169 Added silc_string_regex_combine to combine to regex strings
5170 into one so that they can be used as one regex string by
5171 the GNU regex library. Added into the file
5172 lib/silcutil/silcutil.[ch].
5174 Added silc_string_regex_match to match two strings. It returns
5175 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5177 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Imported GNU regex to the soruce tree into lib/contrib.
5180 Fixed some compiler warning from the regex.c.
5182 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Fixed MOTD command in the server to work in router environment.
5186 * Fixed the MOTD command in the client library to support
5187 the server argument in the command.
5189 * Added `nickname_len' argument to the silc_idlist_add_client
5190 in the server, as the `nickname' argument may be binary data
5193 * Added silc_idlist_get_channels to return all channels from
5196 * Implemented LIST command to the server. Affected file is
5199 * Implemented the LIST command to the client library and on the
5202 * Added [<user count>] argument to the LIST command reply.
5203 With private channels the user count is not shown.
5205 * Updated TODO and README.
5207 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * The client entry's data.registered must be TRUE even with
5210 global client entry on global client list. The data.registered
5211 is used to check whether the client is anymore in the network,
5212 for example with WHOWAS command so it must be valid.
5214 * Fixed the WHOWAS command in the server. It now actually works
5215 in router environment. Added function into silcd/command_reply.c
5216 silc_server_command_reply_whowas_save.
5218 * Added silc_idlist_purge function to the silcd/idlist.c
5219 to periodically purge the ID Cache.
5221 * Fixed INFO command in the server. It works now in router
5222 environment. Added <server name> argument to the INFO command
5223 reply. Updated the protocol specs.
5225 * Fixed minor bug in silc_idcache_purge to not purge if the
5226 expire value is zero.
5228 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5229 they were buggy because of the WHOWAS information.
5231 * Fixed local command MSG to handle the async resolving of
5232 the remote client properly. It used to fail the first MSG.
5233 Affected file silc/local_command.c.
5235 * Added `data_len' field to SilcIDCache context.
5237 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Update TODO. Todo in commands in the server.
5241 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5244 used by routers as broadcast packet to inform other routers
5245 about the changed user mode.
5247 Implemented the notify handling in the server. Affected file is
5248 silcd/packet_receive.c. Added the function
5249 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5251 * Added new generic Channel Payload and deprecated the New Channel
5252 Payload. The New Channel Payload is now the generic Channel
5255 * Added new argument `mode' to the silc_server_send_new_channel
5256 as it is required in the Channel Payload now.
5258 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5259 and created a new and real SilChannelPayload to represent the
5260 new generic Channel Payload. Implemented the encode/decode
5261 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5263 * Added silc_server_get_client_channel_list to return the list
5264 of channels the client has joined for WHOIS command reply.
5265 Affected file silcd/server.[ch].
5267 * Implemented the channel list sending in the WHOIS command reply
5268 in server and in the client.
5270 Implemented the channel list displaying on the user interface
5271 as well. Affected file silc/client_ops.c.
5273 * Added silc_channel_payload_parse_list to parse list of Channel
5274 Payloads. It returns SilcDList list of SilcChannelPayloads.
5275 Client for example can use this function to parse the list of
5276 channels it receives in the WHOIS command reply. The caller
5277 must free the list by calling silc_channel_payload_list_free.
5278 Affected files lib/silccore/silcchannel.[ch].
5280 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Added one new argument <user mode> to the WHOIS command reply
5283 to return the mode of the user in SILC. Updated the protocol
5286 Implemented it to the server and client.
5288 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Fixed the mode printing on the user interface on joining.
5291 Affected file silc/client_ops.c.
5293 * Implemented the UMODE command and user modes in general to the
5294 client library and to the user interface.
5296 * Implemented the UMODE command to the server.
5298 * The server now sends UNKNOWN_COMMAND error status if client sends
5299 unknown command. Affected file silcd/command.c.
5301 * All server commands now handle the command identifier the right
5302 way when sending the command reply to the client. The client can
5303 use to identify the command replies with the identifier.
5305 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added silc_server_get_client_route to resolve the route to
5308 the client indicated by the client ID. Affected file is
5311 * Added silc_server_relay_packet as general function to relay
5312 packet to arbitrary destination. This deprecates functions
5313 like _send_private_message_key, _relay_notify etc. Affected
5314 file is silcd/packet_send.[ch].
5316 Removed silc_server_send_key_agreement,
5317 silc_server_send_private_message_key and
5318 silc_server_packet_relay_notify functions from the file
5319 silcd/packet_send.[ch].
5323 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5324 server. Affected file silcd/packet_receive.[ch].
5326 * Implemented the KILL command to the client. Implemented the
5327 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5328 Affected files lib/silcclient/command[_reply].c and
5329 lib/silcclient/client_notify.c. Implemented the KILL notify
5330 printing in the user inteface.
5332 * Fixed a lot silc_parse_nick memory leaks from the client
5333 library in the file lib/silcclient/command.c.
5335 * Changed the silc_server_send_notify_on_channels's `sender'
5336 argument from SilcSocketConnection to SilcClientEntry to
5337 check the sender as entry and not as connection object and not
5338 to send to the client provided as argument. The affected file
5339 is silcd/packet_send.[ch].
5341 * The notify packets that are destined directly to the client used
5342 to not to be processed by the server. Now changed that and the
5343 server processes all notify packets. After relaying the packet
5344 to the client the notify packet is processed in the server.
5346 * The silc_server_free_client_data now checks whether there is
5347 pending outgoing traffic for the client and purges the data to
5348 the network before removing the client entry.
5350 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5353 an client is killed from the SILC Network. Updated the protocol
5356 Added new function silc_server_send_notify_killed to the
5357 silcd/packet_send.[ch].
5359 * Added function silc_server_packet_relay_notify to relay notify
5360 packets that are destined directly to a client. In this case
5361 the server does not process the notify packets but merely relays
5362 it to the client. Affected file silcd/packet_send.[ch].
5364 Added also silc_server_packet_process_relay_notify to check
5365 whereto relay the notify. Affected file is
5366 silcd/packet_receive.[ch].
5368 * Implemented the KILL command to the server.
5372 * Added the backup schema desgined last fall to the protocol
5373 specs for everyone to see. The specification is in the
5374 *-spec-xx.txt draft and the packet type definitions for the
5375 backup routers is in *-pp-xx.txt draft. Thusly, added also
5376 new packet type SILC_PACKET_CELL_ROUTERS.
5378 * A big security problem in the implementation discovered. The
5379 signoff of an client did not cause new channel key generation
5380 which it of course should've done. The channel keys must be
5381 always re-generated when client leaves (or signoffs) the channel.
5382 The silc_server_remove_from_channels funtion now handles
5383 the channel key re-generation.
5385 * Added `sender' argument to the silc_server_send_notify_on_channels
5386 to not to send the client provided as argument. Affected file
5387 silcd/packet_send.[ch].
5389 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Implemented OPER and SILCOPER commands into the server and
5394 * Added silc_auth_verify and silc_auth_verify_data to verify
5395 the authentication directly from the authentication payload.
5396 It supports verifying both passphrase and public key based
5397 authentication. Affected file lib/silccore/silcauth.[ch].
5399 * Added `hash' field to the SilcIDListData structure. It is the
5400 hash negotiated in the SKE protocol. Affected file is
5403 * Slight redesigning of the SilcAuthPayload handling routines.
5404 Do not send SilcPKCS but SilcPublicKey as argument.
5406 * Implemented the public key authentication support to the
5407 serverconfig. The public key is loaded from the provided path
5408 and saved as authentication data to void * pointer. Thus,
5409 changed the unsigned char *auth_data to void *auth_data;
5411 * Fixed SHUTDOWN command to send the reply before the server
5412 is shutdown. :) Affected file silcd/command.c.
5414 * Fixed fatal bug in CONNECT command. The hostname was invalid
5415 memory and server crashed. Affected file silcd/command.c.
5417 * Fixed fatal bug in CLOSE command. The server_entry became
5418 invalid but was referenced later in the command. Affected file
5421 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Fixed fatal bug in failure packet handling. Server ignored
5424 the failure and thus crashed when it came.
5428 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5430 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5431 that the command may be executed only once in (about) 2 seconds.
5432 The old SILC_CF_LAG flag is same but allows command bursts up
5433 to five before limiting.
5435 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5436 server code. Various commands now includes the CF_LAG_STRICT
5437 flag to disallow any kind of miss-use of the command.
5439 * Fixed the silc_buffer_unformat to not to allocate any data
5440 if the length of the data is zero. It used to allocate the
5441 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5443 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Changed the format of AdminConnection configuration section
5446 in the server. Added username of the admin to the format.
5447 Affected files silcd/serverconfig.[ch].
5449 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5450 to return admin configuration data by host, username and/or
5453 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Implemented WHOWAS command to the server. Added the functions:
5457 silc_server_command_whowas_parse,
5458 silc_server_command_whowas_send_reply,
5459 silc_server_command_whowas_from_client and
5460 silc_server_command_whowas_from_server
5462 * Added <Client ID> argument to the WHOWAS command reply. Updated
5463 the protocol specs accordingly.
5465 * Implemented WHOWAS command and command_reply to the client
5468 Implemented the WHOWAS printing on the user interface.
5470 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Added new argument to the WHOWAS command reply, the real name.
5473 It is an optional argument. Updated the protocol specs.
5475 * Added SilcIDCacheDestructor callback that is registered when
5476 the SilcIDCache is allocated. The callback is called when
5477 an cache entry in the ID Cache expires, or is purged from the
5478 cache. Added into lib/silccore/idcache.[ch].
5480 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5481 to destruct the client entries when the cache entry expires.
5482 Other ID Cache's in server and in the client library ignores
5485 * If the ID Cache entry's `expire' field is zero then the entry
5486 never expires. Added boolean `expire' argument to the
5487 silc_idcache_add function in the lib/silccore/idcache.[ch].
5488 If it is TRUE the default expiry value is used.
5490 * Added silc_server_free_client_data_timeout that is registered
5491 when client disconnects. By default for 5 minutes we preserve
5492 the client entry for history - for WHOWAS command.
5494 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Added support to the server to enforce that commands are not
5497 executed more than once in 2 seconds. If server receives
5498 commands from client more frequently, timeout is registered
5499 to process the commands. Affected file silcd/command.c.
5500 Added new function silc_server_command_process_timeout.
5502 * Changed NICK_NOTIFY handling in client library to check that
5503 if the client's nickname was changed, so there is no need to
5504 resolve anything from the server.
5506 * Removed error printing from the WHOIS and IDENTIFY commands.
5507 If error occurs then it is ignored silently in the client library.
5508 The application, however, may map the received error to
5509 human readable error string. The application currently maps
5510 the NO_SUCH_NICKNAME error to string.
5512 * Made the command status message public to the application. Moved
5513 them from lib/silcclient/command_reply.c to
5514 lib/silcclient/command_reply.h. The application can map the
5515 received command status to the string with the
5516 silc_client_command_status_message function.
5518 * Added check to the server to check that client's ID is same
5519 as the Source ID in the packet the client sent. They must
5522 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Added dist-bzip hook to the Makefile.am to make bzip2
5525 compressed distributions.
5527 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Server now enforces the maximum length for the nickname and
5530 the channel as protocol specification dictates. 128 bytes for
5531 nickname and 256 bytes for channel name.
5533 * Moved the WHOIS printing to the application. The client libary
5534 does not print out the WHOIS information anymore, the application
5535 must do it. Renamed silc_client_command_reply_whois_print to
5536 the silc_client_command_reply_whois_save.
5538 The client's idle time is also sent to the application now, and
5539 the idle is shown on screen.
5541 * Added silc_client_command_reply_identify_save to save the
5542 received IDENTIFY entries.
5544 * Do not check for channel private keys in message sending and
5545 reception if the channel does not have the PRIVKEY mode set.
5546 Affected file lib/silclient/client_channel.c.
5548 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5551 just surfaced after chaning the JOIN procedure.
5553 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added silc_client_get_clients_by_list to get client entries
5556 from Client ID list, that is returned for example by JOIN
5557 and USERS command replies. The application should use this
5558 function for example when JOIN command reply is received to
5559 resolve the clients already on the channel (library does not
5560 do that anymore as USERS command reply is not used in the JOIN
5561 procedure anymore). Affected files lib/silcclient/silcapi.h and
5562 lib/silcclient/idlist.c.
5564 * JOIN command reply and USERS command reply returns now SilcBuffer
5565 pointers instead of unsigned char pointers when returning
5566 the client list and mode list.
5568 * Added <Client ID> argument to the JOIN command reply, mainly
5569 for the server to identify for which client the command was
5570 originally sent. Updated protocol specs accordingly.
5572 * Added SilcDlist private_key pointer to the SilcChannelEntry
5573 in the client to support the channel private keys. Affected
5574 file is lib/silcclient/idlist.h.
5576 * Added SilcChannelPrivateKey argument to the function
5577 silc_client_send_channel_message so that application can choose
5578 to use specific private ke if it wants to. If it is not provided,
5579 the normal channel key is used, unless private keys are set.
5580 In this case the first (key that was added first) is used
5581 as the encryption key.
5583 * Implemented the support for channel private key handling.
5584 Implemented the following functions:
5586 silc_client_add_channel_private_key,
5587 silc_client_del_channel_private_keys,
5588 silc_client_del_channel_private_key,
5589 silc_client_list_channel_private_keys and
5590 silc_client_free_channel_private_keys
5592 Affected file lib/silcclient/client_channel.c.
5594 * Added the support for the private keys in the channel message
5595 sending and encryption and in the message reception and
5596 decryption. Affected funtions are
5597 silc_client_send_channel_message and silc_client_channel_message.
5599 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Added SKE's key verify callback to the client library's
5602 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5604 * Removed the statement that server (or router) must send USERS
5605 command reply when joining to the channel so that the client
5606 knows who are on the channel. Instead, the client list and
5607 client's mode list is now sent in the JOIN command reply to the
5608 client who joined channel. This is better solution.
5610 * Added function silc_server_get_users_on_channel and function
5611 silc_server_save_users_on_channel to the silcd/server.[ch].
5613 * Removed function silc_server_command_send_users from the
5616 * Do not show topic on the client library anymore. The topic is
5617 sent in the command reply notify to the application and the
5618 application must show the topic now.
5620 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Added client searching by nickname hash into the IDENTIFY and
5623 WHOIS commands in the server as they were clearly missing from
5624 them. Affected file is silcd/command.c.
5626 * Fixed a bug in private message receiving in the client library.
5627 The remote ID was freed and it wasn't supposed, now it is
5630 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Minor fix to the channel payload; allocate the data area, as it
5633 needs to be of specific length.
5635 * If the key agreement port is zero then the operating
5636 system will define the bound port. Affected files are
5637 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5639 * Added new function silc_channel_payload_decrypt into the file
5640 lib/silccore/silcchannel.[ch].
5642 * Moved the channel message etc, check from silc_packet_decrypt
5643 to applications. The library calls now a generic
5644 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5645 when the packet is either normal or special. This was done to
5646 allow more wide range of checking that was not allowed when
5647 the code was in library. Now applications can do virtually any
5648 checks to the packet and return to the library the decision how
5649 the packet should be processed. Affected files are
5650 lib/silccore/silcpacket.[ch].
5652 Added silc_server_packet_decrypt_check to the server and
5653 silc_client_packet_decrypt_check to the client library.
5655 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5656 to send with specified source and destination information.
5658 * Channel message delivery between routers was broken after the
5659 channel key distribution was fixed earlier. The channel key
5660 was used be to distributed to other routers as well which is not
5661 allowed by the protocol. Now this is fixed and channel keys
5662 really are cell specific and the channel message delivery between
5663 routers comply with the protocol specification.
5665 * Fixed various commands in server to check also the global list
5666 for the channel entry and not just the local list. The affected
5667 file silcd/command.c.
5669 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Added assert()s to buffer formatting and unformatting routines
5672 to assert (if --enable-debug) when error occurs. Affected
5673 file: lib/silcutil/silcbuffmt.c.
5675 * Changed to auto-reconnect to check whether the remote host is
5676 router and register the re-connect timeout if it is. It used
5677 to check that whether we are normal server, but router must do
5678 auto-reconnect with another router as well. Affected file
5681 * Removed the [<key len>] option from CMODE command as the cipher
5682 name decides the key length, nowadays. See the defined ciphers
5683 from the protocol specification.
5685 * Added [<hmac>] option to the CMODE command to define the HMAC
5686 for the channel. Added SILC_CMODE_HMAC channel mode.
5688 * Added [<hmac>] option for the JOIN command so that user can
5689 select which HMAC is used to compute the MACs of the channel
5692 * Added Hmac field to the Channel Message Payload. The integrity
5693 of plaintext channel messages are now protected by computing
5694 MAC of the message and attaching the MAC to the payload. The
5695 MAC is encrypted. Now, it is clear that this causes some
5696 overhead to the size of the packet but rationale for this is that
5697 now the receiver can verify whether the channel message decrypted
5698 correctly and also when private keys are set for the channel the
5699 receiver can decrypt the packet with several keys and check from
5700 the MAC which key decrypted the message correctly.
5702 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5703 lib/silccrypt/silccipher.[ch].
5705 * Added silc_hash_len to return the digest length into the
5706 lib/silcrypt/silchash.[ch].
5708 * Rewrote parts of Silc Channel Payload interface in the
5709 lib/silccore/silcchannel.[ch]. The encode function now also
5710 encrypts the packet and parse function decrypts it.
5712 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Fixed a minor formatting bug in the SKE's key material processing.
5715 It actually might have processed the keys wrong way resulting
5718 * Redefined the mandatory HMAC algorithms and added new algorithms.
5719 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5720 and hmac-md5 truncated to 96 bits. The mandatory is now
5721 hmac-sha1-96. Rest are optional (including the one that used
5722 to be mandatory). Rationale for this is that the truncated HMAC
5723 length is sufficient from security point of view and can actually
5724 make the attack against the HMAC harder. Also, the truncated
5725 HMAC causes less overhead to the packets. See the RFC2104 for
5728 * Added new [hmac] configuration section. The SKE used to use
5729 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5730 is of course wrong. The official names that must be proposed in
5731 the SKE are the ones defined in the protocol specification
5732 (hmac-sha1-96 for example). The user can configure any hmac
5733 using any hash function configured in the [hash] section. At
5734 least, the mandatory must be configured.
5736 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5738 * Added HMAC list to the SKE proposal list. It has now both
5739 hash algorithm list and HMAC list. This makes the protocol
5740 incompatible with previous versions. The SKE now seems to work
5741 the way it is supposed to work, for the first time actually.
5743 * Defined plain Hash algorithms to the protocol specification.
5746 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Implemented support for key agreement packets into the server.
5749 Added functions silc_server_key_agreement and
5750 silc_server_send_key_agreement. Other than these functions,
5751 server has nothing to do with this packet.
5753 * Added support for private message key packets into the server.
5754 Added functions silc_server_private_message_key and
5755 silc_server_send_private_message_key.
5759 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5760 called in the protocol's final callback instead in the END
5761 protocol state. This makes a little more sense and in the same
5762 time in client we can use the same protocol routines for normal
5763 key exchange and to key agreement packet handling as well.
5765 * Added to both client's and server's KE protocol context the
5766 SilcSKEKeyMaterial pointer to save the key material. We will
5767 bring the key material to the protocol's final callback by doing
5768 this. The final callback must free the key material.
5770 * Added SKE's packet_send callback into client's KE protocol
5771 context so that the caller can choose what packet sending function
5772 is used. This way we can use different packet sending when
5773 doing normal SKE when doing key agreement packet handling (in
5774 the key agreement packet handling we do not want to encrypt
5777 * Implemented the responder side of the key agreement routines
5778 in the client. The client can now bind to specified port and
5779 accept incoming key negotiation. The key material is passed
5780 to the application after the protocol is over.
5782 * Implemented the processing of incoming Key Agreement packet
5783 in the client. Added function silc_client_key_agreement to
5786 * Implemented the intiator side of the key agreement routines
5787 in the client. The client can now initiate key agreement with
5788 another remote client. The key material is passed to the
5789 application after the protocol is over.
5791 * Created client_keyagr.c to include all the key agreement
5794 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5795 SILC_TASK_CALLBACK except that it is not static.
5797 * Created client_notify.c and moved the Notify packet handling
5798 from the client.[ch] into that file.
5800 * Created client_prvmsg.c and moved all private message and
5801 private message key routines from the client.[ch] into that file.
5803 * Create client_channel.c and moved all channel message and
5804 channel private key routines from the client.[ch] into that file.
5806 * Changed silc_client_get_client_by_id_resolve to resolve with
5807 WHOIS command instead of IDENTIFY command, in the file
5808 lib/silclient/idlist.c.
5810 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Implemented the SKE's responder side to the Client library.
5814 * When FAILURE is received to the protocol do not trust it
5815 blindly. Register a timeout to wait whether the remote closes
5816 the connection as it should do it, only after that process the
5817 actual failure. This was changed to both client and server.
5819 * Added client_internal.h to include some of the structures
5820 there instead of client.h in lib/silcclient/.
5822 * Added function silc_task_unregister_by_callback to unregister
5823 timeouts by the callback function.
5825 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Some "Incomplete WHOIS info" errors has been appearing on the
5828 log files. Took away the entry->userinfo check from WHOIS
5829 reply sending. The entry->userinfo is now " " if client did not
5830 provide one. I thought this was fixed earlier but something
5831 is wrong still. Let's see if the error still appears.
5833 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5835 * Fixed a minor bug in the login when the channel key is
5836 re-generated in the server. It used to generate the key in
5837 wrong order and thus caused problems in the channel traffic.
5839 * Fixed a minor bug in channel key distsribution after
5840 KICK command. The key was not sent to the router even though
5843 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added silc_ske_process_key_material_data as generic routine
5846 to process any key material as the SILC protocol dictates. The
5847 function is used by the actual SKE library but can be used by
5848 applications as well. This relates to the private message keys
5849 and the channel private keys since they must be processed the
5850 same way the normal SILC session keys. The protocol dictates
5851 this. Affected files: lib/silcske/silcske.[ch].
5853 Added also silc_ske_free_key_material to free the
5854 SilcSKEKeyMaterial structure.
5856 * Defined silc_cipher_set_key function to set the key for
5857 cipher without using the object's method function. The affected
5858 files: lib/silccrypt/silccipher.[ch].
5860 * Implemented silc silc_client_add_private_message_key,
5861 silc_client_add_private_message_key_ske,
5862 silc_client_del_private_message_key,
5863 silc_client_list_private_message_keys and
5864 silc_client_free_private_message_keys functions in the
5867 Added functions silc_client_send_private_message_key to send
5868 the Private Message Key payload and silc_client_private_message_key
5869 to handle incoming Private Message Key payload.
5871 * Added Cipher field to the Private Message Key payload to set
5872 the cipher to be used. If ignored, the default cipher defined
5873 in the SILC protocol (aes-256-cbc) is used.
5875 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Removed lib/silcclient/ops.h file.
5879 Redefined parts of the SILC Client Library API. Created new
5880 file silcapi.h that deprecates the ops.h file and defines the
5881 published Client Library API. Defined also private message key
5882 API and channel private key API into the file.
5884 This is the file that the application must include from the
5885 SILC Client Library. Other files need not be included by
5886 the application anymore.
5888 * Added new key_agreement client operation callback and also
5889 defined the Key Agreement library API for the application.
5891 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5894 is used by clients to request key negotiation between another
5895 client in the SILC network. If the negotiation is started it
5896 is performed using the SKE protocol. The result of the
5897 negotiation, the secret key material, can be used for example
5898 as private message key.
5900 Implemented the Key Agreement payload into the files
5901 lib/silccore/silauth.[ch].
5903 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Redefined ciphers for the SILC protocol. Added some new ciphers
5906 and defined the key lengths for the algorithms. Changed the
5907 code accordingly. The default key length is now 256 bits.
5909 * Fixed SKE key distribution function silc_ske_process_key_material
5910 when the key length is more than 128 bits. The default key
5911 length in SILC is now 256 bits.
5913 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5914 to indicate unsupported algorithm.
5916 * Renamed rijndael.c to aes.c and all functions as well.
5918 * Fixed a long standing channel key setting bug in client library.
5919 Weird that it has never surfaced before.
5921 * Fixed bug in channel deletion. If the entire channel is removed
5922 then it must also delete the references of the channel entry
5923 from the client's channel list as the client's channel entry and
5924 the channel's client entry share same memory.
5926 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Implemented CONNECT and SHUTDOWN commands in the client.
5930 * Implemented CLOSE command to the client.
5932 * Added the function silc_idlist_find_server_by_name into the
5933 files silcd/idlist.[ch].
5935 Added the function silc_idlist_find_server_by_conn into the
5936 files silcd/idlist.[ch].
5938 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * DIE command was renamed to SHUTDOWN. Updated the both code
5943 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5944 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5946 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5949 * Added function silc_server_create_connection function to create
5950 connection to remote router. My server implementation actually
5951 does not allow router to connect to normal server (it expects
5952 that normal server always initiates the connection to the router)
5953 so the CONNECT command is only good for connecting to another
5956 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5959 or some other client was kicked from the channel.
5961 Implemented the handling of the notify type to both client
5964 Implemented silc_server_send_notify_kicked to send the KICKED
5965 notify. It is used to send it to the server's primary router.
5967 * Implemented the KICK command into server and client.
5969 * Added `query' argument to the silc_idlist_get_client function
5970 to indicate whether to query the client from server or not if
5973 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5974 to indicate that the client is not channel founder.
5978 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Removed the rng context from SilcPacketContext structure and
5981 changed that the packet routine uses the Global RNG API.
5983 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Added support for quit message that client can "leave" on the
5986 channel when it quits the SILC. It is ditributed inside the
5987 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5989 Added silc_server_free_client_data that will take the
5990 signoff message as argument.
5992 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5994 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Updated parts of the protocol specification to keep it up
5999 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6002 payloads in one packet.
6004 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6005 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6006 use now the new List flag.
6008 * Also deprecated the following packet types: REPLACE_ID,
6009 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6011 * Added list support for Notify packet in server.
6013 * Added silc_server_send_notify_channel_change to send the
6014 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6015 the silc_server_send_replace_id.
6017 * Added silc_server_send_notify_nick_change to send the
6018 NICK_CHANGE notify type. Deprecates the function
6019 silc_server_send_replace_id.
6021 * Added silc_server_send_notify_join to send the JOIN notify type.
6022 Deprecates the function silc_server_send_new_channel_user.
6024 * Added silc_server_send_notify_leave to send LEAVE notify type.
6025 Deprecates the function silc_server_send_remove_channel_user.
6027 * Added silc_server_send_notify_cmode and
6028 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6029 types. Deprecates the silc_server_send_set_mode function.
6031 * Added SERVER_SIGNOFF notify type to indicate that server has
6032 quit. This means that all clients on the channel from that
6033 server will drop. This can be also used when netsplit happens.
6035 Deprecated REMOVE_ID packet type since it is not needed anymore
6038 Added silc_server_send_notify_server_signoff to send the
6039 SERVER_SIGNOFF notify type. Deprecates the function
6040 silc_server_send_remove_id.
6042 Added also silc_server_send_notify_signoff to send the
6043 SIGNOFF notify type.
6045 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6046 SILC protocol from this day on. Changed the protocol
6047 specification as well.
6049 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6050 notify type. It is used between routers to notify about
6051 topic changes on a channel.
6053 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6056 * Partly updated the protocol specification to comply with the
6057 changes now made. It is still though a bit outdated.
6059 * The JOIN notify type now takes one extra argument <Channel ID>.
6060 The packet used to be destined to the channel but now the
6061 JOIN type may be sent as list thus it is impossible to
6062 destine it to any specific channel. By adding this argument
6063 it is again possible.
6065 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Added CREDITS file. The CHANGES and CREDITS file will appear
6068 in the distribution as well.
6070 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6073 types in the server's silcd/packet_receive.c.
6075 * Implemented CMODE and CUMODE to work in router environment.
6077 * Fixed minor encoding and decoding buglet from the
6078 lib/silccore/silcmode.c.
6080 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6083 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6085 * Changed all SilcConfigServer* and silc_config_server* to
6086 SilcServerConfig* and silc_server_config*, respectively.
6089 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Associated the ID (client or server ID) to the Authentication
6092 Payload to avoid any possibility of forging. Updated the
6093 protocol specification and the code accordingly.
6095 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * The RSA key length is now save to the RsaKey context in the
6098 key generation process in lib/silccrypt/rsa.c. The key length
6099 is now used to figure out the maximum size of the block allowed
6100 to be encrypted/signed.
6102 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6103 is equivalent to the silc_mp_mp2bin but does not allocate any
6106 * Changed silc_mp_mp2bin API to take length argument. If it is
6107 non-zero then the buffer is allocated that large. If zero, then
6108 the size is approximated using silc_mp_sizeinbase, which however
6111 * Created Global RNG API which is global RNG that application can
6112 initialize. After initializing, any routine anywhere in the
6113 code (including library) can use RNG without allocating a new
6114 RNG object. This was done to allow this sort of use of the
6115 RNG in code that has no chance to allocate RNG object. All
6116 applications currently allocate this and many routines in the
6117 library use this. Affected file lib/silccrypt/silcrng.[ch].
6119 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6120 it to use the Global RNG API.
6122 * Defined Authentication Payload into protocol specification that
6123 is used during SILC session to authenticate entities. It is
6124 used for example by client to authenticate itself to the server
6125 to obtain server operator privileges.
6127 Implemented this payload into the lib/silccore/silcauth.[ch].
6128 Implemented also routines for public key based authentication
6129 as the new protocol specification dictates.
6131 Moved definitions of different authentication methods from
6132 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6134 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6135 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6136 silc_pkcs_verify_with_hash functions into the file
6137 lib/silccrypt/silcpkcs.[ch].
6139 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * The client entry's userinfo pointer must be always valid.
6142 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6143 will fail since it requires the userinfo. Now, the userinfo
6144 is allocated as "" if actual userinfo does not exist. Actually,
6145 it must exist and it is totally Ok to drop client connections
6146 that does not announce the userinfo. However, we will make
6147 this workaround for now.
6149 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6150 to return the remote port by socket.
6152 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6155 SILC_SERVER_PENDING_EXEC and added an new macro
6156 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6157 data or when error occurs while processing the pending command.
6159 Added new argument `destructor' into silc_server_command_pending
6160 and to the SilcServerCommandPending object. This destructor is
6161 now called after calling the pending callback or if error occurs
6162 immediately. If error occurs the actual pending callback won't
6163 be called at all - only the destructor. The destructor may be
6164 NULL if destructor is not needed.
6166 All this applies for client library code as well. Similar
6167 changes were made there as well for the pending commands.
6169 In the client, the application must now allocate the
6170 SilcClientCommandContext with the silc_client_command_alloc
6173 * Added reference counter to the SilcServerCommandContext. Added
6174 function silc_server_command_alloc and silc_server_command_dup
6177 Same type of functions added to the client library for the same
6180 * Removed the cmd_ident from IDListData away since it is now
6181 global for all connections. It is the command identifier used
6182 in command sending and with pending commands. The affected file
6185 * Added reference counter to the SilcSocketConnection objecet to
6186 indicate the usage count of the object. The object won't be
6187 freed untill the reference counter hits zero. Currently only
6188 server uses this, and client ignores it. The client must be
6189 set to use this too later. The affected files are
6190 lib/silccore/silcsockconn.[ch]. Added also the function
6191 silc_socket_dup to increase the reference counter.
6193 This was mainly added because it is possible that the socket
6194 is removed underneath of pending command or other async
6195 operation. Now it won't be free'd and proper DISCONNECTING
6196 flags, etc. can be set to avoid sending data to connection that
6197 is not valid anymore.
6199 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6200 the connection. After that it sets SILC_SET_DISCONNECTED.
6201 It is, however, possible that the socket data is not still freed.
6202 The silc_server_packet_process now checks that data is not
6203 read or written to connection that is DISCONNECTED. The socket
6204 get's freed when the reference counter hits zero.
6206 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Changed the client operation API: channel_message operation's
6209 `sender' is now the client entry of the sender, not the nickname
6210 and the `channel' is the channel entry, not the channel name.
6212 In the private_message operation the `sender' is now also the
6213 client entry of the sender not the nickname.
6215 Affected file is lib/silcclient/ops.h and all applications
6216 using the client operations.
6218 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6220 * Moved the calling of ops->connect() from connect_to_server_final
6221 into receive_new_id functin since that is the point when the
6222 client is actually allowed to send traffic to network. The
6223 affected file is lib/silcclient/client.c.
6225 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6228 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6229 (if needs broadcasting) instead of broadcasting the packets one
6230 by one which would make a burst in the network traffic.
6232 * Added `broadcast' argument to the functions in silcd/server.[ch]
6233 silc_server_create_new_channel[_with_id] to indicate whether
6234 to send New Channel packet to primary router.
6236 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Added new function into the silcd/server.[ch] files:
6239 silc_server_create_new_channel_with_id to create new channel with
6240 already existing Channel ID.
6242 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6243 lib/silccore/silcpacket.h. This packet is used t send list of
6244 Set Mode payloads inside one packet. Server uses this to set
6245 the modes for the channels and clients on those channels, that it
6246 announced to the router when it connected to it. The protocol
6247 specification has been updated accordingly.
6249 * The silc_server_new_channel did not handle the packet coming
6250 from normal server as it normally does not send that. However,
6251 when it announces its channels it does send it. Implemented
6252 the support for that.
6254 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6255 into the file lib/silccore/id.h.
6257 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Fixed memory leaks in the functions silc_idlist_del_client,
6260 silc_idlist_del_channel and silc_idlist_del_server in the file
6261 silcd/idlist.c. All of those leaked like a sieve.
6263 * Fixed some small memory leaks in the client's function
6264 silc_client_notify_by_server.
6266 * Added functions into silcd/server.c: silc_server_announce_clients,
6267 silc_server_announce_channels and silc_server_announce_server.
6268 These functions are used by normal and router server to announce
6269 to its primary router about clients, channels and servers (when
6270 router) that we own. This is done after we've connected to the
6273 These functions effectively implements the following packet types:
6274 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6275 and SILC_PACKET_NEW_ID_LIST.
6277 * Added new functions into the silcd/packet_receive.[ch]:
6278 silc_server_new_id_list, silc_server_new_channel_list and
6279 silc_server_new_channel_user_list to handle the incoming
6280 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6282 * Added support of changing Channel ID in the function
6283 silc_server_replace_id. If the server that announces a channel
6284 to the router already exists in the router (with same name but
6285 with different Channel ID), router is responsible to send
6286 Replace ID packet to the server and force the server to change
6287 the Channel ID to the one router has.
6289 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6290 client that the Channel ID has been changed by the router. The
6291 normal server sends this to the client. Client must start using
6292 the new Channel ID as the channel's ID.
6294 Implemented handling of this new type into lib/silcclient/client.c
6295 into the function silc_client_notify_by_server.
6297 * Added new function silc_idlist_replace_channel_id into the files
6298 silcd/idlist.[ch] to replace the Channel ID.
6300 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Call silc_server_command_identify_check always when processing
6303 the IDENTIFY command in silcd/command.c
6305 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6308 send keepalive packets. The packet can be sent by clients,
6309 servers and routers.
6311 Added function silc_socket_set_heartbeat into the file
6312 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6313 If not set, the heartbeat is not performed. The actual
6314 heartbeat is implemented in the low level socket connection
6315 library. However, application is responsible of actually
6318 Added silc_server_send_heartbeat to send the actual heartbeat
6319 packet into silcd/packet_send.[ch]. Server now performs
6320 keepalive with all connections.
6322 * Added silc_task_get_first function into lib/silcutil/silctask.c
6323 to return the timeout task with shortest timeout. There was a bug
6324 in task unregistration that caused problems. TODO has been
6325 updated to include that task system must be rewritten.
6327 * The client library will now resolve the client information when
6328 receiving JOIN notify from server for client that we know but
6329 have incomplete information.
6331 * Rewrote parts of silc_server_remove_from_channels and
6332 silc_server_remove_from_one_channel as they did not remove the
6333 channel in some circumstances even though they should've.
6335 * Encryption problem encountered in server:
6337 The LEAVE command used to send the Channel Key packet to the
6338 router immediately after generating it. However, the code
6339 had earlier sent Remove Channel user packet but not immediately,
6340 ie. it was put to queue. The order of packets in the router
6341 was that Channel Key packet was first and Remove Channel User
6342 packet was second, even though they were encrypted in the
6343 reverse order. For this reason, MAC check failed. Now, this
6344 is fixed by not sending the Channel Key packet immediately but
6345 putting it to queue. However, this is more fundamental problem:
6346 packets that are in queue should actually not be encrypted
6347 because packets that are sent immediately gets encrypted
6348 actually with wrong IV (and thus MAC check fails). So, packets
6349 that are in queue should be encrypted when they are sent to
6350 the wire and not when they put to the queue.
6352 However, the problem is that the current system has not been
6353 designed to work that way. Instead, the packet is encrypted
6354 as soon as possible and left to the queue. The queue is then
6355 just purged into wire. There won't be any fixes for this
6356 any time soon. So, the current semantic for packet sending
6359 o If you send packet to remote host and do not force the send
6360 (the packet will be in queue) then all subsequent packets to the
6361 same remote host must also be put to the queue. Only after the
6362 queue has been purged is it safe again to force the packet
6365 o If you send all packets immediately then it safe to send
6366 any of subsequent packets through the queue, however, after
6367 the first packet is put to queue then any subsequent packets
6368 must also be put to the queue.
6370 Follow these rules and everything works fine.
6372 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Added new function silc_server_remove_clients_by_server to
6375 remove all client entries from ID list when the server connection
6376 is lost. In this case it is also important to invalidate all
6377 client entires as they hold the invalid server entry. This
6378 fixes fatal bug when server has lost connection and will reconnect
6381 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Made some sanity checks to silc_server_daemonise like to check
6384 whether the requested user and group actually exists.
6386 * Added sanity check to SKE's silc_ske_responder_finish to check
6387 that the public and private key actually is valid.
6389 * Invalidate the client's nickname when receiving Replace ID
6390 packet and the Client ID is being replaced. This means that the
6391 server will query the nickname if someone needs it (client)
6394 * Sort the ID Cache in client library when the ID Cache data
6395 has changed (needs sorting).
6397 * Do not allow for SILC client to create several connections to
6398 several servers. The client does not support windows right now
6399 and generating multiple connections causes weird behaviour.
6401 Irssi-silc client does support windows and can handle several
6402 connections without problems, see: www.irssi.org and SILC plugin.
6404 * Fixed some places where client was added to the IDList. The
6405 rule of thumb is following (in order to get everything right):
6406 If the client is directly connected local client then the
6407 `connection' argument must be set and `router' argument must be
6408 NULL to silc_idlist_add_client function. If the client is not
6409 directly connected client then the `router' argument must
6410 bet set and the `connection' argument must be NULL to the
6411 silc_idlist_add_client function.
6413 * The funtion silc_server_packet_send_local_channel actually did
6414 not check whether the client was locally connected or not. It
6415 does that now. Fixed a bug related to LEAVE command.
6417 * Fixed Remove Channel User payload parsing bug in server's
6418 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6420 * The server's silc_server_save_channel_key now checks also the
6421 global ID list for the channel as it might not be in the local
6422 list. Fixed a bug related to LEAVE command.
6424 * Is this the end of the [<unknown>] buglet that has been lurking
6425 around for a long time? A little for loop fix in server's
6426 silc_server_command_whois_parse that is used by both IDENTIFY
6427 and WHOIS command. At least, this was a clear bug and a cause
6428 of one type of [<unknown>] buglet.
6430 * WHOIS and IDENTIFY commands call the function
6431 silc_server_command_[whois/identify]_check function even if
6432 we are not router server.
6434 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Added --with-gmp configuration option. If set the GMP
6437 is always compiled in the SILC source tree. If not set then
6438 it is checked whether the system has the GMP3 installed. If
6439 it has then the GMP won't be compiled (the system's headers
6440 and library is used), if it doesn't have it then the GMP is
6441 compiled in the SILC source tree.
6443 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Changed RSA private exponent generation to what PKCS #1
6446 suggests. We try to find the smallest possible d by doing
6447 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6448 not security fix but optimization.
6450 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added new config entry [Identity] to fork the server and run
6453 it as specific user and group. A patch from Bostik.
6455 * Imported Dotconf configuration library into lib/dotconf.
6456 This will be used to create the SILC configuration files later.
6457 It will appear in the distsribution after this commit.
6459 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * A big code auditing weekend happening. Auditing code for
6462 obvious mistakes, bugs and errors. Also, removing any code
6465 Removed files for being obsolete:
6467 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6468 inline in the file lib/silcutil/silcbuffer.h)
6470 o lib/silcutil/silcbufutil.c (the header has inline versions)
6472 Changed code to fix possible error conditions:
6474 o The buffer formatting routines now check that the destination
6475 buffer really has enough space to add the data. This applies for
6476 both buffer formatting and unformatting
6477 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6478 unformatting was changed to accomodate following rules:
6479 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6480 sent to the function while XXX_*STRING will not allocate or copy
6481 the data into the buffer. Instead it sets the pointer from the
6482 buffer into the pointer sent as argument (XXX_*STRING used to
6483 require that the pointer must be allocated already). This change
6484 makes this whole thing a bit more consistent and more optimized
6485 (note that the data returned in the unformatting with XXX_*STRING
6486 must not be freed now). The routines return now -1 on error.
6488 o Tried to find all code that use buffer_format and buffer_unformat
6489 and added return value checking to prevent formatting and
6490 especially unformatting errors and possible subsequent fatal
6493 o Changed ske->x and ske->KEY to mallocated pointers in
6494 lib/silcske/silcske.h. Fixed possible data and memory leak.
6496 o Added return value checking to all *_parse* functions. Fixed
6497 many memory leaks as well.
6499 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6500 so that buffer overflows would not happen. All code now also
6501 checks the return value as it can fail.
6503 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added reconnection support to server if the normal server looses
6506 its connection to the router (for example if router is rebooted).
6507 The server performs normal reconnection strategy implemented
6508 to the server. Affected file silcd/server.c.
6510 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Added new packet type SILC_PACKET_SET_MODE that is used to
6513 distribute the information about changed modes (for clients,
6514 channels and clients channel modes) to all routers in the
6515 network. Updated the protocol specification accordingly.
6517 Added functions into silcd/packet_send.c and
6518 silcd/packet_receive.c: silc_server_send_set_mode,
6519 silc_server_set_mode.
6521 Added new files silcmode.[ch] into lib/silccore that implements
6522 the encoding and decoding of Set Mode Payload. Added new type
6523 SilcSetModePayload. Moved the definitions of different modes
6524 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6526 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Oops, a little mistake in server's connection authentication
6529 protocol. The protocol is not ended with FAILURE but with
6530 SUCCESS if the authentication is Ok. :) Affected file is
6533 * Implemented NICK_CHANGE notify handling in server in the file
6534 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6535 the local clients on the channel. After the changing nickname
6536 in router environment snhould work and the [<unknown>] nickname
6537 should appear no more.
6539 The silc_server_replace_id function that receives the Replace ID
6540 payload now sends the NICK_CHANGE notify type also in the file
6541 silcd/packet_receive.c
6543 * Changed WHOIS and IDENTIFY command to support the maximum amount
6544 of arguments defined in protocol specs (3328 arguments). This
6545 fixed a bug that caused problems when there were more than three
6548 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Added extra parameter, command identifier, to the
6551 silc_client_send_command so that explicit command identifier
6554 Changed that ID list routines uses specific command identifier
6555 when sending WHOIS/IDENTIFY requests to the server so that they
6556 can be identified when the reply comes back.
6558 Affected files lib/silcclient/command.[ch],
6559 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6561 * Added `sender' argument to silc_server_packet_send_to_channel
6562 to indicaet the sender who originally sent the packet to us
6563 that we are now re-sending. Ignored if NULL. Affected file
6564 silcd/packet_send.[ch].
6566 * Added some server statistics support in silcd/server_internal.h
6567 SilcServerStatistics structure and around the server code. Also
6568 send some nice statistics information when client is connecting
6571 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Fixed channel ID decoding in server's JOIN command reply in
6574 silcd/command_reply.c
6576 * Fixed braodcasting of replace ID payload to not to send it if
6577 we are standalone server in silcd/packet_receive.c.
6579 * Fixed all channel message sending routines to not to send
6580 packets to clients that has router set, since they are routed
6581 separately in the same function earlier. Affects file
6582 silcd/packet_send.c and all channel packet sending functions.
6584 * In USERS reply, res_argv[i] are not allocated, the table
6585 is allocated. Thus changed that free the table, not its
6588 * In server's whois_check and identify_check if the client is
6589 locally connected do not send any WHOIS commands - they are not
6592 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Fixed some minor bugs in client when sending WHOIS command. The
6595 arguments was in wrong order.
6597 * Removed statis function add_to_channel from server in
6598 silcd/command.c that was previously used with the joining but
6601 * Tested USERS command in router environment successfully with two
6602 routers, two servers and two clients.
6604 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Reorganized the USERS command and command reply in client library
6607 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6608 When the command is given by user we register a pending command
6609 callback that will reprocess the command after the reply has been
6610 received from the server. When reprocessing the packet we then
6611 display the information. Thus, the USERS information is displayed
6612 now in the command callback instead of in the command reply
6613 callback. The processing of the command is same as previously
6614 when server has sent the command reply in the JOINing process.
6616 * Added to USERS command in silcd/command_reply.c to join the client,
6617 we didn't use to know about, to the channel after we've created
6618 a client entry for it. Also, for clienet we did know already still
6619 check whether it is on the channel or not and add it if not.
6621 * Removed silc_server_command_join_notify as the function and its
6624 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Changed the client's pending command handling to the same as the
6627 server's pending command handling. It is also now possible to
6628 execute command reply functions from other command reply
6629 function as the function callbacks for commands and command
6630 replies are one and same. The pending commands are not static
6631 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6632 in client connection context. Thus, pending commands are server
6633 connection specific as it is convenient.
6635 Changed the function silc_client_command_pending and
6636 silc_client_command_pending_del and added new function
6637 silc_client_command_pending_check. Removed the
6638 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6641 * Added cmd_ident, current command identifier, to the client
6642 connection context in lib/silcclient/client.h to keep track on
6643 command identifiers used in command sending. Client's command reply
6644 function handling now supports the mandatory command identifiers.
6646 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6647 funtions in client to fully support pending command callbacks.
6649 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6650 as one of the arguments to the application in the command reply
6653 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6654 before first releasing SILC but came back. Now it is removed again
6655 and should come back nomore. The FORWARDED flag was used only
6656 by the JOINing procedure by forwarding the command packet to router.
6657 Now, the JOINing procedure has been changed to more generic (due
6658 to various router environment issues) and FORWARDED is not needed
6659 anymore for anything. The protocol specification is yet to be
6662 Now, removed silc_server_packet_forward from server and the flag
6663 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6665 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Renamed NAMES command to USERS command. The NAMES was named that
6668 due to historical reasons. Now it is renamed. Also, rewrote
6669 parts of the USERS command. The nickname list is not sent anymore
6670 by the server. Only Client ID and mode lists are sent in the USERS
6671 command. Changed this also to the protocol specification.
6673 The client now resolves the names and stuff after it receives
6674 the USERS list from the server when joining to the channel.
6676 * WHOIS and IDENTIFY commands has been changed to support multiple
6677 Client ID's per command. One can now search for multiple users
6678 in the network by sending only one WHOIS or IDENTIFY command.
6679 Changed the code and the protocol specifications.
6681 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6682 uses silc_server_command_whois_parse to parse the request. */
6684 * If normal server, do not parse the WHOIS and IDENTIFY requests
6685 before sending it to the router. Saves some time.
6687 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Fixed JOIN command on client library. Wrong number of arguments
6690 used to crash the client.
6692 * Added silc_server_channel_has_global function to check whether
6693 channel has global users or not.
6695 * Added silc_server_channel_has_local function to check whether channel
6696 has locally connected clients on the channel.
6698 * The silc_server_remove_from_one_channel now checks whether the
6699 channel has global users or not after given client was removed from
6700 the channel. It also checks whether the channel has local clients
6701 on the channel anymore. If it does not have then the channel entry
6702 is removed as it is not needed anymore.
6704 * The silc_server_notify now checks on JOIN notify whether the joining
6705 client is one of locally connected or global. If it is global then
6706 the channel has now global users on the channel and that is marked
6707 to the channel entry. Also, it now saves the global client to
6708 global list who is joining and JOINs it to the channel. This is
6709 for normal server, that is.
6711 Changed silc_server_send_notify_on_channel,
6712 silc_server_packet_relay_to_channel and
6713 silc_server_packet_send_to_channel check if we are normal server
6714 and client has router set (ie. global client) do not send the
6715 message to that client, as it is already routed to our router.
6717 * Implemented LEAVE notify type handling in silc_server_notify
6720 * Tested LEAVE command in router environment successfully. Tested
6721 with two routers, two servers and two clients.
6725 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6727 * Implemented SIGNOFF notify type handling in silc_server_notify
6730 * silc_server_remove_id now removes the client entry from all channels
6731 it has joined and thusly sends SIGNOFF notify type.
6733 * Rewrote the NAMES list generation in server by removing two excess
6734 loops. The lists are created now inside one loop.
6736 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * silc_server_remove_channel_user checks now also global list
6739 for channel and client.
6741 * silc_server_new_channel_user checks now both local and global
6742 list for channel and client. Fixed a bug in client id decoding.
6743 Used to decode wrong buffer.
6745 * silc_server_channel_message checks now both local and global
6746 list for channel entry.
6748 * Tested channel joining (hence JOIN) in router environment
6749 successfully. Tested with two routers, two servers and two
6752 * Tested channel message sending in router environment successfully.
6754 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added silc_server_save_channel_key into server.[ch] to save the
6757 received channel key in Channel Key payload processing. It is
6758 also used in JOIN command reply handling.
6760 Equivalent function silc_client_save_channel_key added into
6761 client.[ch] into client library.
6763 * Changed JOIN command reply to send information whether the channel
6764 was created or not (is existing already) and the channel key
6765 payload. Changed protocol specs accordingly.
6767 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6768 the request was sent by ID and not by nickname. Crashed on
6771 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6774 now correctly save the received data.
6776 * silc_server_free_sock_user_data now notifies routers in the
6777 network about entities leaving the network.
6779 At the same time implemented functions silc_server_remove_id
6780 and silc_server_send_remove_id to receive and send REMOVE_ID
6781 packets. The packet is used to notify routers in the network
6782 about leaving entities. The ID removed will become invalid in
6785 * Added function silc_idlist_del_server into server. Removes and
6786 free's server entry from ID list.
6788 * silc_server_private_message function now checks, if we are router,
6789 that the destination ID really is valid ID, naturally.
6791 * In router when NEW_ID packet is received (for new client) the
6792 hash of the Client ID is saved in the ID Cache but the
6793 client->nickname is set to NULL, instead of putting the hash
6796 IDENTIFY command now also checks that client->nickname must be
6797 valid. If it is not if will request the data from the server who
6798 owns the client. Added new function
6799 silc_server_command_identify_check.
6801 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6802 to set the command to already allocated Command Payload.
6804 * Tested private message sending in router environment with two
6805 routers, two servers and two clients. Fixed minor bugs and now
6808 * Fixed segfault from client's NAMES command. Used to crash if
6811 * Forwarded packets must not be routed even if it is not destined
6812 to the receiver. Changed server code comply with this.
6814 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * Added `require_reverse_mapping' boolean value to ServerParams
6817 structure. If TRUE (not default) the server will require that
6818 the connecting host has fully qualified domain name.
6820 If the reverse mapping is not required and hostname could not be
6821 found the IP address is used as hostname.
6823 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Implemented version string checking to both client and server.
6826 The check is incomplete currently due to the abnormal version
6827 strings used in development version of SILC.
6829 * Changed all command functions in server to use the new
6832 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Changed char *data to unsigned char *data in ID Cache system to
6835 support binary data as ID Cache data. Changed code to support
6836 binary data in lib/silccore/idcache.c.
6838 * Renamed silc_server_packet_relay_command_reply to
6839 silc_server_command_reply as it is normal packet receiving
6840 function. Rewrote the function to accept command replys for
6841 servers and not only for clients.
6843 * Mark remote router always as registered server if we are connecting
6844 to it. Otherwise, commands sent by the router to us are ignored.
6846 * All ID List find routines now returns the ID Cache Entry pointer
6847 as well if requested.
6849 * WHOIS command works now in router environment, tested with two
6850 routers, two servers and two clients.
6852 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6853 in router environment (as it is almost equivalent to WHOIS) but
6854 hasn't been tested thoroughly. Added new functions:
6856 silc_server_command_identify_parse
6857 silc_server_command_identify_send_reply
6858 silc_server_command_identify_from_client
6859 silc_server_command_identify_from_server
6861 * Disabled route cache adding because adding two different ID's with
6862 same IP replaces the old cache entry thus giving wrong route.
6863 The entry->router->connection is always the fastest route anyway
6864 so route cache may not be needed. Of course, new routes maybe
6865 established after receiving the ID when the entry->router->connection
6866 might not be anymore the most optimal.
6868 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Add route cache for received ID for fast routing.
6872 * Added silc_server_packet_route to route received packet on router
6873 that is not destined to us.
6875 * Renamed silc_server_get_route to silc_server_route_get.
6877 * Added id_string and id_string_len fields into SilcServer to
6878 include encoded ServerID for fast comparing without excess
6879 encoding of the ID's.
6881 * Cleaned up WHOIS command on server side. Added following static
6884 silc_server_command_whois_parse
6885 silc_server_command_whois_check
6886 silc_server_command_whois_send_reply
6887 silc_server_command_whois_from_client
6888 silc_server_command_whois_from_server
6890 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6891 arguments in command replies. All command functions should be
6892 updated to use this macro.
6894 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Minor typo fixes on command reply handling on server.
6898 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Added silc_server_command_add_to_channel internal routine to add
6901 the client to the channel after router has created the channel and
6902 sent command reply to the server.
6904 * Added generic silc_server_send_command to send any command from
6907 * Use static buffer with ID rendering instead of duplicating data.
6909 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6911 * Fixed a channel user mode bug when joining to a channel server gave
6912 everybody channel founder rights, oops.
6914 * We mark ourselves as the router of the incoming server connection
6915 if we are router ourselves. This way we can check in some packet
6916 sending functions whether it is locally connected server. For
6917 incoming router connections we put NULL.
6919 * For router sending packets locally means now always sending the
6920 packet cell wide; to local clients and local servers. For normal
6921 server sending packet locally means sending it to only local
6924 * Fixed the JOIN command to really work in router environment. If the
6925 channel is created it is always created by the router. Router is
6926 also responsible of making the initial joining to the channel,
6927 sending JOIN notify to the sending server and distributing
6928 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6929 does not exist server doesn't do anything else but forward the
6930 command to the router which performs everything.
6932 * Added silc_server_send_channel_key function to send the Channel Key
6935 * Added silc_server_create_channel_key to create new channel key. The
6936 channel key is now re-generated everytime someone joins or leaves
6937 a channel, as protocol dictates. Note: channel->key_len is the
6940 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6943 packet_receive.[ch] to separate packet sending and receiving
6944 routines. The server.[ch] now includes everything else including
6945 actual packet processing (writing and reading data) and other
6948 Renamed silc_server_private_message_send_internal to
6949 silc_server_send_private_message. The routine is still though
6950 used only to relay private messages as server does not send
6951 private messages itself.
6953 Renamed silc_server_new_channel to silc_server_create_new_channel
6954 and added new function sicl_server_new_channel that handles the
6955 incoming New Channel packet. Added also new sending function
6956 silc_server_send_new_channel to send New Channel Payload.
6958 * Added new function silc_server_notify to process incoming notify
6959 packet to the server/router. Server may then relay the notify
6960 to clients if needed.
6962 * Added new function silc_server_new_channel_user to process incoming
6963 New Channel User packet. Router will redistribute the packet and
6964 send JOIN notify to its local clients and locally connected servers
6965 if needed. Normal server will send JOIN notify to its local client
6966 on same channel when received this packet. Added also corresponding
6967 sending function silc_server_send_new_channel_user to sent the
6970 * Added boolean route argument to send_notif_to_channel and
6971 packet_send_to_channel functions to attempt to route the packet
6972 if it is TRUE and send only locally if it is FALSE.
6974 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * silc_server_replace_id now broadcasts the received replace ID
6977 packet if it is not broadcast packet already. The router must
6978 broadcast to inform other routers about changed ID.
6980 * Added backpointer to server's router into SilcServer context in
6981 silcd/server_internal.h.
6983 * Fixed silc_server_packet_broadcast to send correct broadcast
6986 * The channel key is now distributed to the local client as soon
6987 as it is received from the router (in router environment) so that
6988 no other packet may be sent for the channel until client has
6991 * silc_server_remove_channel_user now broadcasts the received
6992 Remove Channel User packet if it is not broadcast packet already.
6993 The router must broadcast to inform other routers about removed
6996 * Added users field into SilcPacketContext that is a reference count
6997 of the context. One can increase the reference count by calling
6998 silc_packet_context_dup which is now changed to just increase the
6999 reference count instead of duplicating the data. The reference
7000 count is decresed by calling silc_packet_context_free that will
7001 free the data after the reference count hits zero.
7003 For now on the packet context and everything allocated into it
7004 (including the raw packet from network) must be freed by calling
7005 the new silc_packet_context_free function. Added also new function
7006 silc_packet_context_alloc that must be used now to allocate the
7007 context. This also means that if a routine is asynchronous from
7008 silc_[client/server]_packet_parse_type the packet context must
7009 be duplicated by calling silc_packet_context_dup. Otherwise it
7010 gets free'd after silc_[client/server]_packet_parse_type returns.
7011 Also, one must remember that if packet is duplicated then its
7012 reference count must be decresed by calling the free function as
7013 many times as it was duplicated.
7015 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7016 from both client and server.
7018 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Made joining to a channel working in router environment.
7022 * Cleaned up JOIN command on server side and create function
7023 silc_server_command_join_channel internal routine to make the
7026 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Changed silc_command_pending list to SilcDList. Also, added
7029 `ident' field to SilcServerCommandPending structure to identify
7030 the reply and to call correct callback.
7032 Added silc_server_command_pending_check function to replace the
7033 corresnponding macro. The silc_command_pending list is not
7036 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7037 to set identifier to previously allocated Command Payload. It
7038 is used to set identifier for command when resending Command
7041 * Added silc_command_payload_encode_payload to encode Command
7042 Payload buffer from SilcCommandPayload structure.
7044 * Added silc_argument_payload_encode_payload to encode Argument
7045 payload buffer from SilcArgumentPayload structure.
7047 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Changed WHOIS command to support router connection on server side.
7050 The whois request is always sent to router unless the server is
7051 standalone server. After server has received the reply from the
7052 router will it send the reply to the client.
7054 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7055 broadcast received broadcast packet. The function is used only
7056 by router. The broadcast packet is always sent to the router's
7059 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7060 render given ID to printable string, for log files for example.
7062 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Made basic router to router connections working. At least they
7065 can now connect to each other but nothing really works the way
7066 they are supposed - yet.
7068 * Added new initiator token to RouterConnection configuration
7069 file in silcd/serverconfig.[ch]. It is used to tell whether we
7070 are the initiator to the remote router or whether we'll expect
7071 the other end to connect.
7073 * Moved registering of listener task to silc_server_init, hence
7074 the server starts listenning as soon as it is run, even if it
7075 does not have connections to other routers. Let's see how well
7078 * Changed default connection retry timeouts for more suitable in
7081 * Removed cipher and such arguments from silc_idlist_add_client
7082 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7083 Added new function silc_idlist_add_data to add the keys and stuff
7086 * Added SilcIDListData structure and added it to SilcClientEntry
7087 and SilcServerEntry as their first field in the structure. This
7088 way we can explicitly cast the ID entries to the SilcIDListData
7089 structure and get common data for the entries. In past, we had
7090 to first check what type of connection it is and then cast it to
7091 correct ID entry type. Now, we can directly cast the opaque
7092 pointer to the SilcIDListData (no matter what ID entry it actually
7093 is) and get the data needed.
7095 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7097 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7098 in some circumstances even if threre were timeout tasks, though not
7099 IO tasks, but tasks anyway. Now fixed.
7101 * Defined SilcServerConnection structure to hold connection specific
7102 stuff about directly connected servers and routers. The definition
7103 is currently in silcd/server_internal.h. I thought about having
7104 a bit more important role fro this struct but for now it is used
7105 only when connecting to other server (or router actually).
7107 * Added connecting retry support in server when connecting to
7108 router(s). The retry feature implement exponential backoff
7109 algorithm. Also, added SilcServerParams structure to hold default
7110 parameters for server. For now, it include these retry settings
7111 and are hard coded. After server is moded to be as Silc Server
7112 Library this structure will be more important.
7114 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Changed client librarys channel->clients table to SilcList and
7117 changed code accordingly.
7119 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Changed client's channel table to SilcList and changed code
7122 accordingly. Also changed SilcChannelClientEntry to include back-
7123 pointer to the channel so that client entry can use that structure
7124 as list as well and we have fast cross-reference to the channel.
7125 This change dramatically decreased the complexity of channel
7126 handling with client entry and vice versa (removed one extra
7127 loop when searching for channel entry from many functions).
7129 * Changed server->sim from table to SilcDList and changed code
7132 * NAMES command can now be used from user interface. It will show
7133 the user list on the channel, neatly.
7135 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7136 Code now saves realname of the user if it becomes available.
7138 * Renamed configure.in to configure.in.pre and made ./prepare
7139 script to automatically add correct version string to
7140 configure.in which it creates from configure.in.pre.
7142 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * NAMES command reply now shows users mode with the nickname when
7147 * Moved silc_client_ch[u]mode[_char] functions from
7148 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7149 place sucks, they are utility functions and should be in some
7152 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7154 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7157 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Added TRQ (efficient deque and list library) into lib/trq. This is
7162 a very good list library that is currently used in the SILC. Defined
7163 SilcList API over the library because I didn't like the API very
7164 much. See lib/trq/silclist.h for the API and examples of how to
7165 use the API. Fixed various places in the code to use the new
7166 SilcList API. The SilcList is meant for lists that has a structure
7167 already defined as a list. It is not suitable to add just some
7168 context to the list (in TRQ, the context is the list actually).
7170 So, I defined SilcDList that can be used for the purpose where
7171 predefined list structure does not exit. This can be used as
7172 such list. Now some context just can be added to the SilcDList.
7173 Currently this list is not used in the SILC just yet, though there
7174 are a lot places where this can replace dynamically allocated
7175 tables and I will fix these places, later, to use SilcDList.
7176 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7177 and use TRQ internally).
7179 Also fixed some annoying warning messages that the original TRQ
7180 code generated. Also minor changes to TRQ's Makefile.in.
7182 * Added support for querying by Client ID to both WHOIS and
7183 IDENTIFY commands into server, as required by the protocol.
7185 * Removed method function pointers from SilcBuffer structure. They
7186 weren't used to anything and just increased the context size for
7187 no good reason. This change also made silc_buffer_alloc and
7188 silc_buffer_free functions inline functions.
7190 * Disabled command flooding detection support until it's fixed so
7191 that it accepts commands in but does not execute them more than once
7194 * Added silc_net_localhost(), to return local hostname, into
7195 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7196 that must be initialized before calling silc_client_init.
7198 * Added new function: silc_server_send_notify_on_channels to send
7199 notify messages to all channels client has joined. It is assured
7200 that the message is sent only once per client.
7202 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7203 lib/silcutil/silcutil.[ch] as silc_format function. The new
7204 function is generic and is used by server as well, not only by
7205 the logging routines.
7207 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7208 the provided version string was not acceptable. Added new function:
7209 silc_ske_check_version into lib/silcske/silcske.h. The function
7210 must be implemented by the application (client or server) and it
7211 does not reside in the SKE library. The function checks the version
7212 string remote end sent.
7214 * Added back pointers (to opaque context and to SilcSocketConnection)
7215 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7217 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7218 duplicate packet context structure.
7220 * Changed `notify' client operation to send same arguments as client
7221 receives from server except for ID's. ID's are mapped to correct
7222 ID entry and that is returned. Also, if channel entry is not sent
7223 by server but the notify is for channel the channel entry is sent
7224 to application (otherwise application doesn't know that it is for
7225 channel (library gets it from packet's Destination ID)).
7227 * Added silc_client_remove_from_channels into client library to
7228 remove a client from all channels it has joined to. Used when
7229 received SIGNOFF notify from server. Added also new function
7230 silc_client_replace_from_channels to replace old ID entry with
7231 new ID entry on all channels. Used when received NICK_CHANGE
7234 * Fixed ID Cache list handling in silc_idlist_get_client in
7235 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7236 to get (or query) client by ID.
7238 * Updated TODO list.
7240 * Added connection authentication status message defined by the
7241 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7242 support for these into the code in client and server side.
7244 * Added generic function silc_client_send_command to send any command
7245 with variable argument list. Application should use this function
7246 to send commands if the command functions provided by the library
7247 does not suite for the application's user interface needs.
7249 * Added new `failure' client operation. Application is notified about
7250 received failure packet if client is executing a protocol. In this
7251 case the protocol's execution has failed.
7253 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7254 is required by the protocol.
7256 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7257 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7260 * Added status flag to SilcSKE object to indicate realtime status
7261 of the SKE protocol.
7263 * Application receives now exactly same command reply arguments as
7264 the library receives from server. However, if ID is received the
7265 corresponding ID entry is returned to the application (eg. Client
7266 ID is mapped to correct SilcClientEntry entry and that is returned).
7267 Changed command_reply client operation due to this change.
7269 * Changed all ID's in commands and in command replys as ID Payloads.
7270 Change affected both client and server side codes.
7272 All ID's sent in SILC network (with execption of ID's in SILC
7273 Packet header) are sent in ID Payload to support variable length
7276 * Server now notifies nick changes and notifies all clients on
7277 the channels about the new nickname (about the new Client ID,
7280 * Implemented CMODE command to change channel modes. Supports all
7281 channel modes defined by the protocol specs except ban and invite
7282 lists. (Also, private channel key mode is supported but support for
7283 setting private channel key in client is missing, thus, this mode
7284 has no effect on client side (except that server requires that the
7285 client uses private channel key and normal channel traffic does not
7288 Also, invite mode works per se, but INVITE command does not work
7289 yet correctly, so you can set channel as invite only channel but
7290 inviting clients to the channel does not work (it is yet to be
7291 thought what's the best way to do it).
7293 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7294 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7295 Implemented CUMODE command to change user's mode on the channel.
7296 Supports all modes defined by the protocol specs.
7298 * Added NAMES command reply to return users modes on the channel.
7300 * Removed unnecessary and slow ciphers from lib/silccrypt.
7302 * Set SO_KEEPALIVE option to connection sockets by default.
7304 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7306 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7307 redefined the Notify Payload into protocol specs.
7309 * Added silc_id_payload_parse_id to get ID directly from raw
7312 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7315 accept searching by Client ID as well.
7317 * Added support for LEAVE and SIGNOFF notify types in client library.
7319 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7320 to parse ID Payload from raw data.
7322 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7324 * Added flags parameter into silc_ske_assemble_security_properties
7325 function in lib/silcske/silcske.[ch].
7327 * Changed notify client operation to fit better for notify messages
7328 sent by server. The notify payload received from server is now
7329 passed to the application (after parsing it to SilcNotifyPayload).
7330 It is application's responsibility to retrieve the arguments
7331 from the payload and show the message the way it wants. The message
7332 sent by server is implementation specific.
7334 * Changed public keys to comply with the protocol specification.
7335 Old public keys are not supported anymore and are not compatible.
7337 * Removed nickname from Channel Payload as the latest draft removed
7338 it. The client must resolve the nickname from the NAMES command
7339 reply received when it joined the channel.
7341 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7343 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7345 * Fixed some errors in protocol specification drafts.
7347 * Created lib/silccore/silcnotify.c to implement Notify Payload
7348 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7349 generic payloads described by protocol specifications. The file
7350 includes implementations for ID Payload and Argument Payload.
7352 * Changed Command Payload implementation to use the new Argument
7353 Payload. Changed command_xxxx_payload to command_payload_xxxx
7354 to comply with SILC coding conventions.
7356 * Added suppport for Argument Payload handling in Notify Payload
7357 implementation as protocol requires it. Added the new support
7358 into server and client lib as well.
7360 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7362 * Added support for multiple nicknames on same channel. [n] is
7363 added locally to the nickname if there are more than one same
7364 nicknames on the channel.
7366 * Server now sends all nicknames that matched WHOIS request.
7367 Client also shows the list received from server.
7369 * Added TOPIC command to client side. User can now set and show
7370 current topic on channel.
7372 * Added MOTD command to client and server. Also, server sends the
7373 motd when client connects to the server.
7375 * Changed version strings to comply ISO 8601.
7377 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7379 * Fixed protocol error handling in client library. It should now
7380 cope even if the SKE fails for some reason.
7382 * Made new protocol specification drafts for submitting to IETF.
7384 * Implemented TOPIC command to server in silcd/command.c.
7386 * Added two new notify types into lib/silccore/silcnotify.h:
7387 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7388 notify nickname change and topic setting/change on a channel.
7390 * API change of command_reply operation in client library. The
7391 application gets now the status type received from server as well.
7393 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7397 * Cras fixed and optimized the packet handling even further and
7398 it should work now. Minor change to the prototype of function
7399 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7401 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7403 * Added new function into lib/silcutil/silcschedule.[ch]:
7404 silc_schedule_with_fd to select() a specified fd. The function
7405 returns after timeout expires or data arrives or goes. The
7406 function is used by packet routines to wait that all data is
7407 received from network.
7409 * Fixed data reading from network in lib/silccore/silcpacket.c.
7410 The code now assures that all data is read from the fd and then
7411 continues packet processing. This was a bug fix since the code
7412 used to drop some data in some circumstances.
7414 * Added new function into lib/silcclient/client.[ch]:
7415 silc_client_start_key_exchange to start key exchange after
7416 connection has been established to server. The code internally
7417 now uses this funtion but its main purpose was to provide it
7418 for applications that perform their own connecting. After
7419 application has created a connection it merely calls this
7420 function to start the key exchange between client and server.
7421 The library takes care of everything else after that.
7423 Updated also lib/silcclient/README to explain the usage of
7426 * Do not send to application information that connection has
7427 been established. Application gets notified it by connect
7430 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7432 * Applied cras's patch to add silc_schedule_one function. The
7433 function runs scheduler once and returns.
7435 * Fixed the scheduler after cras messed it up. The timeout
7436 handling works now as it's supposed to work.
7438 * Added into lib/silccore/ silcnotify.h to include notify
7439 message types support. Changed silc_server_send_notify*
7440 functions, in server.[ch], to support those new notify types.
7441 Added the support for the notify types into client library,
7442 as well. Added new notify client operation into ops.h in
7445 * Changed silc_server_packet_send_to_channel to send normal
7446 packets instead of just channel message packets. The function
7447 is now used to send the notify packets to channels. It is not
7448 used to send channel message packets anymore, as server never
7451 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7452 va_arg()s as it seems to require it nowadays. I guess, if SILC
7453 is compiled with older va_arg() the new code should work anyway.
7455 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Splitted core library. Core library (lib/silccore) includes
7458 now only SILC protocol specific core (and common) components.
7459 Created new utility library (lib/silcutil) that includes more
7460 generic purpose stuff. The stuff for util library was taken
7461 from the old core library. This was minor and easy split.
7463 * Created SILC Client Library (lib/silcclient) that includes
7464 implementation of the SILC client without user interface. This
7465 was major move from silc/ directory. The code has been changed
7466 so that it is transparent towards the user interface. The
7467 silc/ directory includes now the same user interface as before
7468 and it uses the new client library. Read lib/silcclient/README.
7469 Basicly, the client library performs everything else related
7470 to SILC except user interface handling. Also, configuration
7471 files are considered to be part of user interface and library
7472 does not handle them.
7474 This change also changed a lot of structures, function naming etc.
7475 Most important change was that SilcClientWindow object was
7476 renamed to SilcClientConnection in the client library. Created
7477 also new file lib/silcclient/ops.h. Also added new files
7478 silc/local_command.[ch] and silc/client_ops.[ch].
7480 All these changes were made to make it easier for user interface
7481 designers to create what ever user interface for the SILC client
7484 It is also expected that the server will be moved to lib
7485 directory as well and SILC Server Library will be created;
7486 sometimes in the future.
7488 * Removed Local commands from lib/silccore/silccommand.h as
7489 they are application specific and new client library does not
7490 handle any of those anymore.
7492 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7493 old client implementation in silc/.
7495 * Added support for callback functions in SILC_LOG_* macros.
7496 Application can now set its own callbacks that will be called
7497 instead of using the default functions that will always print
7498 the debug messages to stderr (or stdout). Also, debugging can
7499 now be disabled by setting silc_debug to FALSE and re-enabled by
7500 setting it to TRUE. Note, that logging will still work even
7501 if debugging is disabled.
7503 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7504 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7505 silc_log_reset_debug_callbacks.
7507 * To enable debugging in silc client one must give now -d
7508 option on command line.
7510 * Changed silc_schedule_init to automatically allocate task queues
7511 if they are not allocated before calling it.
7513 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added GMP 3.1 into math library.
7517 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7519 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7520 a channel in SILC network. The packet is used by servers and
7521 routers to notify other routers that user has left a channel.
7522 This little feature was missing until now. Added the feature
7523 to protocol specification as well.
7525 Added functions: silc_server_send_remove_channel_user and
7526 silc_server_remove_channel_user into server.[ch].
7528 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7529 lib/silccore/silcpacket.h. However, they are not implemented
7532 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Fixed joining to a channel and sending channel messages
7535 between server and router. The channel message sending should
7536 now work inside a cell.
7538 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Fixed the private message sending between server and router.
7541 The private message sending should now work inside a cell.
7543 * Added silc_server_replace_id into server.[ch] to replace
7544 existing ID in the SILC network.
7546 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7547 and silc_idlist_replace_server_id into idlist.[ch] in server.
7549 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Fixed the server to server connections. Server can again now
7552 connect to router. Router to router connections probably does
7555 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7557 * Added dynamic protocol registering support. Now protocols can
7558 registered and unregistered on the fly. Patch by cras.
7560 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * Added lib/contrib directory to hold routines that some platforms
7563 don't have but are needed by SILC.
7565 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7566 into lin/contrib to provide getopt() and getopt_long() for
7567 those who don't have it.
7569 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7571 * Added AWAY command to client. When away message is set and
7572 client receives a private message packet the client automatically
7573 replies to the sender with the away message.
7575 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7576 bug seemed to be the cause of recent problems when compiling
7579 * Added version detection support to SKE protocol specification
7580 and added the new changes to the SKE implementation as well.
7581 There were other minor changes in the SKE protocol as well.
7583 Many changes in lib/silcske/silcske.[ch] and in
7584 lib/silcske/payload.[ch].
7586 * Added ^U functionality, clear input line. Patch from cras.
7588 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7590 * Mainly small bugfixes on core library. Fixed some debugging
7591 logging and buffer overflow in silclog.c.
7593 * Updated config.sub and config.guess on the distribution tree.
7595 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Added command lagging support in server. Client may execute
7598 commands now only once in two seconds.
7600 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7602 * Optimized packet reception. MAC computation and checking is now
7603 also more optimized. A lot previously duplicated code is now
7604 used as generic by both client and server.
7606 * Fixed key pair generation in clientutil.c
7608 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * Added into lib/silccore/silcbufutil.[ch] new function;
7611 silc_buffer_realloc.
7613 * Moved generic packet sending/encryption functions to
7614 lib/silccore/silcpacket.[ch] from client and server. Some
7615 rewriting of the functions.
7617 * Moved all generic packet reception/decryption functions to
7618 lib/silccore/silcpacket.[ch] from client and server. The
7619 packet processing is now much cleaner in both client and server.
7620 These were major changes in both client and server.
7622 * Created many common functions in server to do packet sending.
7623 Previously code were duplicated a lot, this has been removed
7626 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Rewrote major parts of the ID cache system. Don't know
7629 whether it is better now or not but at least the API is more
7632 * Major rewrite on ID cache stuff on client because of the ID
7633 cache API changes. Added idlist.c to client.
7635 * Also major rewrite on ID cache stuff on server as well.
7636 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7637 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7638 in hand, instead they are all put into the ID cache system now.
7639 All server_idlist_* routines uses ID cache now instead of
7640 traversing its own lists (those lists does not exist anymore).
7641 SilcIDList though still exists. Also, SilcXXXEntry's are
7644 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * Finally made the SKE implementation compliant to the protocol
7647 specification. All mp integers are now binary encoded as
7648 opposed being HEX encoded.
7650 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7653 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7654 functions: silc_[encode/decode]_pem. Also added function
7655 silc_encode_pem_file to PEM encode with newlines ('\n') for
7658 * SILC public keys are now encoded either PEM or binary. Same
7659 option is for private keys as well. By default private keys
7660 are binary encoded and public keys PEM encoded. Silly HEX
7661 encoding were removed.
7663 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7664 function to create fingerprints.
7666 * Fixed a bug in SHA1; does not change the original data anymore.
7668 * Partly implemented INFO command on client and server side.
7669 Fixed CLEAR command. Changes to SERVER command; show current
7670 server(s) when giving command without arguments. Added
7671 VERSION command to client.
7673 * Added check to server that unregistered connections cannot
7674 execute commands (unless it is specificly allowed).
7676 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7678 * Fixed screen refresh.
7680 * Fixed channel joining bug from client. On some circumstances
7681 client tried to join to a channel it had already joined.
7683 * Added public key verification process into client's protocol.c.
7684 The client now verifies the public key from user and saves
7685 it into ~./silc/serverkeys/ directory.
7687 Added into: clientutil.[ch]: silc_client_verify_server_key.
7689 * Changed SKE protocol's silc_ske_initiator_finish function
7690 to accept callback function that verifies the received public
7691 key. Removed old silc_ske_verify_public_key function.
7693 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7695 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7696 silc_pkcs_private_key[_data]_set.
7698 * Made the password and public authentication more cleaner in
7699 server's protocol.c.
7701 * Removed historic and obsolete protocol `channel_auth' from
7702 both client and server.
7704 * Removed wrong way of sending command status messages from
7705 server to client in server's command.c. The old way violated
7706 protocol specification.
7708 Changes to silccore/silccommand.[ch]: removed
7709 silc_command_encode_status_payload -> not needed anymore,
7710 changed silc_command_encode_payload_va to accept extra
7711 argument on variable argument list. The argument type must
7712 now be provided to the function. Also, added new function:
7713 silc_command_encode_reply_payload_va which is same as
7714 normal command_encode_payload_va except command status type
7715 is provided as extra argument.
7717 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7719 * Added ~./silc directory handling. The directory includes the
7720 public and private keys for the client.
7722 Added silc_client_check_silc_dir, silc_client_create_identifier
7723 and silc_client_load_keys.
7725 * Implemented SILC protocol compliant public key. Added public
7726 and private key saving to and loading from files.
7728 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7729 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7730 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7731 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7732 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7734 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7735 silc_pkcs_load_[public/private]_key.
7737 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7739 * Added silc_server_get_route (route.[ch]) to get connection
7740 data for the fastest route for given ID.
7742 * Implemented INVITE command on client and server. The command
7743 were re-defined in the SILC Protocol Specification and the
7744 implementation now complies with the specification.
7746 * Implemented PING command on client and server.
7748 * Implemented NAMES command on client and server. The server side
7749 supports currently only normal server not router server yet.
7750 Some changes to NAMES definition in SILC protocol specification.
7752 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * Implemented LEAVE command on client and server.
7756 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7757 again. This change was made to the protocol as well. Server
7758 should not violate the protocol specification anymore.
7760 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7762 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7763 was tested. SOCKS4 was not but should work anyway.
