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

574 whether given configuration value has been given already.
576 Affected files silcd/serverconfig.[c], server.[c].
578 * Splitted the doc/example_silcd.conf.in. Separated the crypto
579 algorithm parts and created new file silcalgs.conf, that
580 is now included from the example_silcd.conf.in.
582 * Optimized the silc_server_connect_to_router_second to take
583 the connection configuration object from the SilcServerConnection
584 object instead of finding it during the connecting phase.
585 Added the configuration object to SilcServerConnection struct.
586 Affected files silcd/server_internal.h, server.c.
588 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

602 * Unified the serverconfig.[ch]'s helper function interface.
603 Affected file silcd/serverconfig.[ch].
605 * Removed doc/example_silc.conf.in since it is redundant.
606 The make install will now install irssi/silc.conf file.
608 * Added new Passphrase and Publickey authentication methods to
609 config file, allowing both public key and passphrase based
610 authentication to be set at the same time.
612 Added `prefer_passphrase_auth' setting in config file which
613 can be used to set to prefer passwd auth if both passwd and
614 public key is set. If not set, public key is preferred.
615 This has effect only when being initiator (responder will try
618 Added support for authentication with passphrase and public key
619 at the same time. The passphrase is tried first always since
620 it is faster to check.
622 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
624 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
626 * Merged the new SILC Config library, with the server parsing

662 * Fixed CUMODE_CHANGE notify handling to change the mode of
663 correct client. Affected file lib/silcclient/client_notify.c.
665 * Make silc_rng_alloc fail if it cannot allocate the sha1
666 hash algorithm. Affected file lib/silccrypt/silcrng.c.
668 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
670 * Fixed the file transfer's key agreement payload to include
671 zero port also if the hostname is NULL because it could not
674 Call file transfer monitor callback now also if error occurs
675 during key agreement protocol.
677 Changed the silc_client_file_send interface to return the
678 SilcClientFileError instead of session id. The session ID
679 is returned into pointer provided as argument.
681 Check that the file exists locally before sending the
682 file transfer request at all.
684 Affected file lib/silcclient/client_ftp.c, silcapi.h.
686 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

695 SILC_LOG_WARNING to give out Warning and not Error. Affected
696 file lib/silcutil/silclog.c.
698 * Fixed the channel message payload decryption in the function
699 silc_channel_message_payload_decrypt to not modify the original
700 buffer before it is verified that the message decrypted
701 correctly. Otherwise, next time it is called with correct
702 channel key it won't encrypt since the payload is corrupted.
703 Affected file lib/silccore/silcchannel.c.
705 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

717 * Fixed a bug in hash table internal routine for traversing
718 the table with foreach callback. The current entry may
719 become invalid in the callback but it was referenced after
720 the callback returned.
722 Do not allow auto rehashing of hash table during the
723 silc_hash_table_foreach operation, for same reasons as it is
724 not allowed for SilcHashTableList. Affected files are
725 lib/silcutil/silchashtable.[ch].
727 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Defined DLLAPI into silcincludes.h and silcwin32.h for

733 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
735 * Fixed private message handling. It used some old code that
736 caused the client to crash. Affecte file is
737 lib/silcclient/client_prvmsg.c.
739 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Added function silc_client_add_channel,
742 silc_client_replace_channel_id, and removed functions
743 silc_client_new_channel_id and silc_idlist_get_channel_by_id
746 * Added cross reference of the joined channels to the
747 SilcClientEntry, and changed the SilcChannelEntry's
748 users list to SilcHashTable. The affected files are
749 lib/silcclient/idlist.[ch].
751 * Fixed a bug in hash table tarversing. While the hash table
752 is traversed with SilcHashTableList the table must not be
753 rehashed. It is now guaranteed that auto rehashable tables
754 are not rehashed while tarversing the list. Also defined that
755 silc_hash_table_rehash must not be called while tarversing
756 the table. Added function silc_hash_table_list_reset that must
757 be called after the tarversing is over. The affected files are
758 lib/silcutil/silchashtable.[ch].
760 * Changed all hash table traversing to call the new
761 silc_hash_table_list_reset in server and in client library.
763 * Added function silc_client_on_channel to return the
764 SilcChannelUser entry if the specified client entry is joined
765 on the specified channel. This is exported to application as
766 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
768 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
770 * Fixed founder regaining problem with JOIN command on normal
771 server. The notify for mode change must be sent always and
772 not only if !cmd->pending. Affected file silcd/command.c.
774 * Fixed the WHOWAS command's reply sending to support the
775 lists correctly. Affected file silcd/command.c.
777 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
779 * When sending JOIN command to router for processing the
780 sender's old command identifier was not saved back to the
781 sender's command context, fixed now. The affected file is
784 * Create the key in JOIN command of the router did not return
785 the channel key, added check for this. Affected file is
788 * Fixed a channel ID update bug in JOIN command reply. Do
789 not directly upgrade the ID but call the function
790 silc_idlist_replace_channel_id if the ID was changed.
791 Affected file silcd/command_reply.c.
793 * Fixed memory leaks from command calling if it would fail.
794 Affected file silcd/command.c.
796 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
798 * Applied patches from cras:
800 Memory leak fixes around libaries, irssi window resize fix,
801 new silclist.h and silcdlist.h, all extern inline changed to
804 * Removed dotconf from lib/dotconf, not needed anymore.
806 * Removed TRQ from lib/trq, not needed anymore.
808 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
809 with server connections. Later this will be configurable
810 in config file after new config file is done. Affected file
813 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
815 * Fixed a crash in server related to channel announcements.
816 Affected file silcd/server.c.
818 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
820 * Fixed memory leaks in silc_server_create_new_channel*
821 functions. Affected file silcd/server.c.
823 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
824 which ID was changed. This way the router will send the
825 user list for the channel again, and server won't be in
826 desync in some rare circumstances. Affected file is
827 silcd/packet_receive.c.
829 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Check for NULL socket pointer in the function
832 silc_server_packet_send_to_channel_real. Affected file

840 * Fixed some header addition to Toolkit distribution in
841 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
843 * Added lib/silcclient/client_ops_example.h as an template
844 file for application programmers to quickly start using
845 the SilcClientOperation functions in their application.
846 Updated the lib/silcclient/README as well to tell about this
847 nice file made available.
849 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Call silc_server_remove_from_channels when removing client
852 entry when NO_SUCH_CLIENT_ID was received. Affected file
853 is silcd/command_reply.c.
855 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
857 * Added server & router operator statistics updating. Affected
858 file silcd/packet_receive.c and silcd/command.c.
860 * Fixed the SERVER_SIGNOFF notify handling on normal server
861 not to save the history information for clients. Same was
862 fixed earlier in remove_clients_by_server function, but not
863 here. Affected file silcd/packet_receive.c.
865 * Raised the default connection-retry count from 4 to 7 in
866 server. Affected file silcd/server.h.
868 * Cancel any possible reconnect timeouts when we start the
869 key exchange. Affected file silcd/server.c.
871 * Do not reconnect on connection failure when SCONNECT was
872 given. Affected files silcd/server.[ch].
874 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
876 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
878 * Fixed the NICK command to always give the unformatted
879 nickname to the one giving the NICK command. If unformatted
880 nickname is cached already it will be formatted and the
881 local entry will always get the unformatted nickname.
882 Affected file lib/silcclient/idlist.c.
884 * Fixed some double frees from client library commands.
885 Affected file is lib/silcclient/command.c.
887 * Fixed CUMODE command in server to assure that no one can
888 change founder's mode than the founder itself, there was a
889 little bug. Affected file silcd/command.c.
891 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
893 * Removed the SilcClientCommandDestructor from the client
894 libary, it is not needed anymore. Affected files are
895 lib/silcclient/silcapi.h, command[_reply].[ch],
896 client_notify, idlist.c.
898 * Fixed GETKEY command to first resolve client, and then
899 resolve the server only if the client was not found, instead
900 of resolving both at the same time. Affected file is
901 lib/silcclient/command.c.
903 * Added silc_client_start_key_exchange_cb and lookup the
904 remote hostname and IP address before starting the key
905 exchange with server. The affected file is
906 lib/silcclient/client.c.
908 * The server's public key is now saved using the IP address
909 of the server and not the servername for the filename.
910 The hostname public key filename is checked as an fall back
911 method if the IP address based filename is not found.
913 Fixed the GETKEY command to save the fetched server key
916 Print the remote server's hostname now when new key is
917 received during connection process. Affected file is
918 irssi/src/silc/core/client_ops.c.
920 * Return always our own public key to the client if it asks
921 for it with GETKEY command. Affected file silcd/command.c.
923 * Removed the use_auto_addr variable from default config
924 file since it was in wrong section. Affected file is
927 * Fixed TOPIC_CHANGE notification to not route it when it
928 was sent using silc_server_send_notify_to_channel function.
929 Affected file silcd/command.c.
931 * Fixed silc_server_send_notify_kicked to send the kicker's
932 Client ID also, it was missing. Affected files are
933 silcd/command.c, silcd/packet_send.[ch].
935 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
937 * Do not save client history information in SERVER_SIGNOFF.
938 Fixes the bug in normal server that it does not detect
939 the client becoming valid after the server becomes back
940 online. Affected file silcd/server_util.c.
942 * Added `sock_error' field into the SilcSocketConnection
943 context. When error occurs during socket operation (read
944 or write) the error is saved. Added also new function
945 silc_socket_get_error to return human readable socket error
946 message. Affected files are lib/silcutil/silcsockconn.[ch],
947 lib/silcutil/unix/silcunixsockconn.c, and
948 lib/silcutil/win32/silcwin32sockconn.c.
950 * The server now prints the socket error message in the
951 signoff for client. Affected file silcd/server.c.
953 * Fixed the `created' channel information sending from router
954 to server in JOIN command. Checks now whether the channel
955 really was created or not and set it according that.
957 Fixed the JOIN command to use the client entry's current
958 ID during the joining procedure instead of the one it sent
959 in the command (it is checked though), since it can change
960 between the packet processing and command processing, and
961 would just case unnecessary pain in the client end. Affected
962 file silcd/command.c.
964 * Fixed a channel key payload sending to use correct channel
965 ID when the server was forced to change the channel's ID by
966 router. Router sent the key payload with the old Channel ID.
967 Affected file silcd/packet_receive.c.
969 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
971 * Call silc_server_save_channel_key only if the key payload
972 was provided in the JOIN command's command reply. Affected
973 file silcd/command_reply.c.
975 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
977 * Fixed silc_mp_sizeinbase to return the value correctly with
978 MPI. Affected file lib/silcmath/mp_mpi.c.
980 * Fixed the stop_server signal to correctly stop the scheduler
981 and gracefully stop the server when SIGTERM or SIGINT signals
982 are received. Affected file silcd/silcd.c.
984 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
986 * Simple handling of TERM and HUP signals. Also added some log
987 flushing call around. Affected file is
990 * Fixed small bugs in silclog.c. Now buffering output will take
991 effect after 10 seconds since startup: This will ensure that
992 no important startup messages are lost. Also output redirection
993 will preserve original format ([Date] [Type] message).
994 Affected file is lib/silcutil/silclog.c.
996 * Added two options to the config file, in the logging section:
997 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
998 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1000 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1002 * Do not print the warning about log files not being initialized
1003 more than once to avoid excess logging. Affected file is
1004 lib/silcutil/silclog.c.
1006 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1007 the SIM copying in make install in Makefile.am.pre.
1009 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1011 * Rewritten silclog APIs. Globally interesting changes follows:
1012 silc_log_set_files() changed to silc_log_set_file().
1013 silc_log_set_callbacks() changed to silc_log_set_callback().
1014 ROBOdoc documented silclog header file.
1015 SilcLogCb now returns bool to wether inihibit the default
1016 handler or not (to keep the old behaviour return always TRUE).
1017 The new APIs should also fix the problem of the
1018 silcd_error.log file that was written in the current directory.
1021 Log files streams will remain opened after silc_log_set_file()
1022 call, means less CPU usage notably on high traffic servers.
1023 File streams are now full buffered, and flushed to the disk
1024 every 5 minutes, lesses HD activity and CPU usage.
1025 Messages can be redirected, allowing admins to configure
1026 one single logfile for all server messages.
1027 the silc_log_quick global variable to activate fast-logging.
1028 Affected files lib/silcutil/silclog.[ch]
1030 * Changed some code to conform new silclog APIs. Affected
1031 files are doc/example_silcd.conf.in, silcd/server.c
1032 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1035 * Fixed a memory leak that could occur in some situations.
1036 Affected file silcd/serverconfig.c.
1038 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1040 * Added the silc_client_del_client to remove the client from
1041 all channels as well. Affected file lib/silcclient/idlist.c.
1043 * Fixed the client library to correctly remove the client
1044 from all channels when the client entry is being destroyed.
1045 Affected file lib/silcclient/client_notify.c, command.c.
1047 * Added auto-nicking support to the client library. If the
1048 applicatio now sets client->nickname it will be sent to the
1049 server after connecting by the library. This way for example
1050 SILCNICK (or IRCNICK) environment variables will have effect
1051 and always change the nickname automatically to whatever
1052 it is wanted. Affected file lib/silcclient/client.[ch].
1054 * Renamed silc_server_command_bad_chars to the
1055 silc_server_name_bad_chars and moved it to the
1056 silcd/server_util.[ch]. Added also new function
1057 silc_server_name_modify_bad to return nickname that
1058 includes bad characters as new nickname without those
1059 bad characters. This check and modify is now used in
1060 silc_server_new_client when the username is initially set
1061 as nickname, so it must be checked to be valid nickname.
1062 Affected file silcd/packet_receive.c.
1064 * The nickname length is now taken from the packet for real
1065 and not trusted to strlen() since it clearly can return
1066 wrong length for nickname including bad characters. This
1067 also applies to channel names. Affected file silcd/command.c.
1069 * Removed the lib/silcsilm/modules directory. Modules are now
1070 compiled into the lib/silcsim. Fixed the copying of the
1071 modules to follow symbolic links in Makefile.am.pre.
1073 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1075 * Fixed silc_string_regexify list creation. Fixes bugs with
1076 BAN and INVITE commands in server. The affected file is
1077 lib/silcutil/unix/silcunixutil.c.
1079 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Removed the command destructor entirely from the server's
1082 command and command reply routines. It is not needed, and
1083 its usage was buggy and caused crashes. Affected files are
1084 silcd/command[_reply].[ch].
1086 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Cancel protocol and NULL sock->protocol if timeout
1089 occurred during protocol. Affected file silcd/server.c.
1091 * Cancel protocol timeouts always before calling the final
1092 callback, to assure that after final callback is called
1093 no other state will be called for the protocol anymore.
1094 Affected file silcd/protocol.c.
1096 * Print error log if incoming connection configuration could
1097 not be found. Affected file silcd/server.c.
1099 * Fixed JOIN command to correctly save the founder mode
1100 to the client on normal SILC server, when the channel
1101 was created by the router. Affected file silcd/command.c.
1103 * Fixed LIST command (hopefully) to send correct reply
1104 packets. Affected file silcd/command.c.
1106 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * The silc_packet_receive_process now returns FALSE if the
1109 read data was invalid packet, and TRUE if it was ok.
1111 The server now checks that if unauthenticated connection
1112 sends data and its processing fails the server will close
1113 the connection since it could be a malicious flooder.
1115 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1117 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Make sure the warning about error opening a log file is
1120 printed only once and not everytime it fails (produces
1121 too much useless log). Affected file lib/silcutil/silclog.c.
1123 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1125 * Made the silc_server_daemonise() function more readable.
1126 Affected file silcd/server.c.
1128 * Pid file is now optional, the user may comment it out from
1129 the config file. Removed define SILC_SERVER_PID_FILE, we
1130 don't need a default any longer. Affected file
1131 configure.in.pre, lib/Makefile.am.pre.
1133 * Make some use of the pid file. The server now dies at startup
1134 if it detects a valid pid file on his path. The server would
1135 die anyway in this circumstance, because of the bind() failure.
1136 Affected file silcd/silcd.c.
1138 * No longer compiling lib/dotconf.
1140 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Fixed JOIN command parsing not to crash. Affected file
1143 lib/silcclient/command.c.
1145 * Fied the NICK_CHANGE notify to add the new client entry
1146 even it is resolved. This removes an <[unknown]> nick
1147 thingy bug in the client. Affected file is
1148 lib/silcclient/client_notify.c.
1150 * Do not try to allocate 0 bytes (efence does not like it)
1151 in lib/silccore/silccomand.c when encoding payload.
1153 * Do not take IRCNICK as nickname in Irssi SILC client since
1154 it is not possible to set nickname before hand connecting
1155 the server (TODO has an entry about adding auto-nicking
1158 * Changed the silc_server_command_pending to check whether
1159 there already exists an pending entry with the specified
1160 command, command identifier and pending callback. This is
1161 to fix IDENTIFY and WHOIS related crashes that may register
1162 multiple pending commands with same identifier. Affected
1163 file silcd/command.c.
1165 * Fixed the server to reconnect to the router even if it
1166 was already reconnecting and EOF was received. This to
1167 fix a possibility that the server wouldn't ever try to
1168 auto-reconnect to the router. Affected file silcd/server.c.
1170 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Fixed the server's password authentication to use the
1173 length of the locally saved password, and not the one
1174 sent in the packet. Affected file silcd/protocol.c.
1176 * Fixed same password authentication problem in the
1177 Authentication Payload handling routines in
1178 lib/silccore/silcauth.c.
1180 * Yet another password authentication problem fixed with
1181 channel password handling in silcd/command.c.
1183 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * If first character of string in silc_parse_userfqdn is '@'
1186 then do not parse it. Affected file is
1187 lib/silcutil/silcutil.c.
1189 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed minor bug in IDENTIFY command reply sending, which
1192 caused various weird problems during JOIN when it was
1193 resolving names for users. Affected file silcd/command.c.
1195 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Fixed the IDENTIFY command reply sending to chech better valid
1198 clients. It was possible to send incomplete list of replies.
1199 Affected file silcd/command.c.
1201 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Added silc_client_command[s]_[un]register functions now to
1204 dynamically register the commands in client library. Removed
1205 the static table of commands. This allows the client library
1206 to call commands without causing the application to know about
1207 what commands library has called.
1209 Removed the INFO command reply kludge to detect when the command
1210 was called by library. Now library use its own command reply
1211 function for INFO command.
1213 Added function silc_client_command_call to call a command.
1214 Application can use it to call command, not access the structure
1217 Now all commands that are sent by the client library (not
1218 explicitly sent by application) use own command reply functions.
1220 Affected files around lib/silcclient/ and in
1221 irssi/src/silc/core/.
1223 * Fixed the WHOIS command reply sending to chech better valid
1224 clients. It was possible to send incomplete list of replies.
1226 Fixed the WHOIS and IDENTIFY to send the request to router
1227 if normal server did not do it and did not find any results.
1229 Affected file silcd/command.c.
1231 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Moved the internal data from SilcClient context into its
1234 own file, not accesible to application. Affected files
1235 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1236 and other files in client library.
1238 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Added doc/examples installation target in Makefile.am.pre.
1243 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1246 commands the found client entry will be removed from the
1247 cache, after notifying application about the error. Affected
1248 file lib/silcclient/command_reply.c.
1250 * Changed the /MSG to check for exact nickname user gave, and
1251 not let `nick' match `nick@host' if it is only one found. Now,
1252 user must type the exact nickname (like nick@host2) even if
1253 there are no more than one same nicks found. This is to avoid
1254 a possibility of sending nickname to wrong nickname since
1255 `nick' could match `nick@host'. Affected file is
1256 irssi/src/core/silc-servers.c.
1258 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Do not print "you are now server operator" or similar when
1261 giving /away command. Affected files are
1262 irssi/src/silc/core/client_ops.c, silc-servers.h.
1264 * Made the silc_server_command_pending_error_check to send
1265 the same command reply payload it received back to the
1266 original sender of the command. This way all arguments
1267 that was received by the server will be received by the
1268 client too. Affected file silcd/command.c.
1270 * Added the silc_idcache_add to return the created cache entry
1271 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1273 * Add global clients to expire if they are not on any channel.
1274 This is because normal server will never know if they signoff
1275 if they are not on any channel. The cache expiry will take
1276 case of these entries. This is done by normal servers only.
1277 The affected files are silcd/command_reply.c,
1278 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1280 * If server receives invalid ID notification for WHOIS or
1281 IDENTIFY and the ID exists in the lists, it is removed.
1282 Affected file silcd/command_reply.c.
1284 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1285 in client then client entry that it matches is searched and
1286 the nickname is printed on the screen for user. Affected
1287 file irssi/src/silc/core/client_ops.c.
1289 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1291 * Use cache entry expire time in the LIST command reply to
1292 purge old entries from the cache after the LIST command
1293 reply has been received. This way we don't have non-existent
1294 entries in the cache for too long. Affected file is
1295 silcd/command_reply.c.
1297 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1299 * If we are normal server, and we've not resolved client info
1300 in WHOIS or IDENTIFY from router, and it is global client,
1301 we'll check whether it is on some channel. If it is not
1302 then we cannot be sure about its validity and will resolve it
1303 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1304 file silcd/command.c.
1306 * Search channel by name (if possible) rather than by ID
1307 in IDENTIFY command's command reply. Affected file is
1308 silcd/command_reply.c.
1310 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1312 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1313 Updated specs and implemented it. Affected file silcd/command.c,
1314 silcd/packet_send.c and silcd/packet_receive.c.
1316 * Implemented the <founder auth> payload handling in the JOIN
1317 command. If provided all conditions for channel joining
1318 except requirement to provide correct passphrase can be
1319 overrided by the channel founder. Updated the protocol specs.
1320 Affected file silcd/command.c.
1322 Added support for founder auth in JOIN command in client
1323 library. Fixed the parsing of the JOIN command now to support
1324 all options as they should be. The affected file is
1325 lib/silcclient/command.c.
1327 * Optimized the WHOIS and IDENTIFY commands to send the request
1328 to router only if it includes nicknames or other names. If
1329 they include only IDs then check the local cache first before
1330 routing. Affected file is silcd/command.c.
1332 * Added channels topic announcements. Affected file is
1333 silcd/packet_receive.c and silcd/server.c.
1335 * Fixed the silc_server_send_notify_topic_set to really destine
1336 the packet to channel. Affected file silcd/packet_send.c.
1338 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1339 library. Affected file lib/silcclient/client_notify.c.
1341 * Added UMODE announcements. Affected file silcd/server.c.
1343 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Memory leak fixes in:
1347 lib/silcutil/silcsockconn.c
1348 lib/silcske/silcske.c
1349 lib/silcske/groups.c
1351 lib/silccrypt/silcpkcs.c
1352 lib/silccore/silccommand.c
1353 lib/silccore/silcidcache.c
1358 * ROBOdoc documented the lib/silcske/groups.h file and a
1359 bit changed the interface for better.
1361 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1363 * Update the client entry context in the ID cache after
1364 nick change. Affected file lib/silcclient/command.c.
1365 Fixes the CUMODE command when regaining founder privileges,
1366 and a little WHOIS problem.
1368 * Fixed silc_net_gethostbyname to correctly call the
1369 inet_ntop. Affected file lib/silcutil/silcnet.c.
1371 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1373 * Added IPv6 support checking to the configure.in.pre, added
1374 also --enable-ipv6 option to override the check. Affected
1375 file configure.in.pre.
1377 * The silc_thread_create now calls the start function
1378 directly if threads support is not compiled in. Removes
1379 ugly #ifdef's from generic code. Affected files are
1380 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1382 * Added silc_net_gethostby[name/addr]_async to asynchronously
1383 resolve. Affected files are lib/silcutil/silcnet.[ch].
1385 * Added support for rendering IPv6 based server, client and
1386 channel IDs. Affected file lib/silcutil/silcutil.c.
1388 * Added support for creating IPv6 based server IDs. Affected
1389 file is silcd/serverid.c.
1391 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1393 * Added silc_net_gethostby[addr/name] into the
1394 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1395 routines. Added silc_net_is_ip[4/6]. Affected file is
1396 lib/silcutil/unix/silcunixnet.c. All routines that take
1397 address as argument now supports both IPv4 and IPv6 addresses.
1399 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1401 * Fixed LIST command reply sending in server. Affected file
1404 * Server now sends the kicker's client ID in the KICK notify
1405 to the kicked client. Affected file silcd/command.c.
1407 * The client library now parses the kickers client ID and
1408 UI displays it. Affected files lib/silcclient/client_notify.c
1409 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1411 * Made all payload parsing function prototypes consistent.
1412 They all take now const unsigned char * and uint32 pair as
1413 the payload data instead of SilcBuffer. Changes all around
1414 the source tree. Other unsigned char* -> const unsigned char*
1415 changes around the tree as well.
1417 * Optimized SFTP client and server packet sending not to
1418 allocate new buffer for each packet but to recycle the
1419 first allocated buffer. Affected files are
1420 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1422 * Optimized the SFTP client to use SilcList instead of
1423 SilcDList for requests, because it is faster. Affected file
1424 is lib/silcsftp/sftp_client.c.
1426 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1427 into lib/silccore/silcid.[ch].
1429 Renamed silcpayload.[ch] into silcargument.[ch].
1431 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * If client entry is deleted with active key agreement
1434 session, abort the session.
1436 The silc_client_abort_key_agreement now calls the completion
1437 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1439 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1442 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Don't use __restrict in older GCC's. Affected file is
1445 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1447 * silc_net_localhost now attempts to reverse lookup the
1448 IP/hostname. Affected file lib/silcutil/silcnet.c.
1450 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1451 command. It can be used to gain founder privileges at
1452 the same time when joining the channel.
1454 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1455 kicker's client ID as well. Updated protocol specs.
1457 Defined that the server must send SILC_COMMAND_IDENTIFY
1458 command reply with error status to client who sent
1459 private message with invalid client ID.
1461 Updated the protocol specification.
1463 * Added silc_server_send_command_reply to send any
1464 command reply. Affected file silcd/packet_send.[ch].
1466 * Added silc_id_payload_encode_data to encode ID payload
1467 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1469 * The server now send IDENTIFY command reply with error
1470 status if client ID in private message is invalid. Affected
1471 file silcd/packet_receive.c.
1473 * Save the server key file with server's IP address in
1474 the filename instead of hostname. The affected file is
1475 irssi/src/silc/core/client_ops.c.
1477 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1482 * Added libtool support for compiling shared objects in
1483 lib/silcsim. Affected file configure.in.pre and
1484 lib/silcsim/Makefile.am. Original patch by cras.
1486 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Pid file configuration, and server's config file fixes
1489 patch by toma. Updated CREDITS file.
1491 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Fixed silc_client_channel_message to not try to decrypt
1494 the message twice if it resolved the destination client
1495 information. This could cause of dropping one channel
1496 message. Affected file lib/silcclient/client_channel.c.
1498 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1501 lib/silcclient/client.c. This function is used when the SILC
1502 Client is run under some other scheduler, or event loop or
1503 main loop. On GUI applications, for example this may be
1504 desired to used to run the client under the GUI application's
1505 main loop. Typically the GUI application would register an
1506 idle task that calls this function multiple times in a second
1507 to quickly process the SILC specific data.
1509 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1511 * Fixed silc_server_drop() for dropping the supplementary
1512 groups as well, this could cause a security hole on some
1515 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

1521 to run server on foreground. A patch by debolaz.
1522 Affected files silcd/server.c, silcd/silcd.c.
1524 * Fixed MOTD to return the MOTD file server name. Affected
1525 file silcd/command.c.
1527 * Added INFO command reply handling to the Irssi SILC Client.
1528 Affected file irssi/src/silc/core/client_ops.c.
1530 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Fixed the silc_idcache_list_* routines to really support
1533 the dynamic list. Fixes a crash. Affected file is
1534 lib/silccore/silcidcache.c.
1536 * Fixed the LIST command reply to really call LIST command's
1537 pending callbacks. Affected file silcd/command_reply.c.
1539 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Update conn->local_entry->nickname after giving NICK
1542 command. Affected file lib/silcclient/command.c.
1544 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1546 * Added the [pid] option to the silcd configuration file
1548 Affected files: serverconfig.[ch] and silcd.c
1550 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1552 * Save fingerprint in WHOIS command reply in server.
1553 Affected file silcd/command_reply.c.
1555 * Fixed NICK commands pending callback registration.
1556 Affected file lib/silcclient/command.c.
1558 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1560 * Use ++server->cmd_ident when sending commands in server,
1561 instead of random number. Affected file silcd/command.c.
1563 * Fixed GETKEY command reply to call actually GETKEY pending
1564 command callbacks. Affected file silcd/command_reply.c.
1566 * A bit stricter check for nicknames. Check for same nickname
1567 in NICK command also. Affected file silcd/command.c.
1569 * Do not call INFO command everytime client ID changes, only
1570 during first connecting. Affected file lib/silcclient/client.c.
1572 * Set the new nickname only after successful command reply for
1573 NICK command is returned by server. Affected file
1574 lib/silcclient/command.c.
1576 * Remove nicknames from nicklist during server_signoff notify.
1577 Should fix /NAMES bit more. The affected file is
1578 irssi/src/silc/core/silc-channels.c.
1580 * Added `fingerprint' field to the SilcIDListData in the
1581 silcd/idlist.h to hold the fingerprint of the client's
1584 Send the fingerprint of the client's public key in WHOIS
1587 Affected files silcd/command.c, and silcd/idlist.[ch].
1589 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1590 create fingerprint from given data.
1592 * Show the fingerprint of the client's public key in WHOIS.
1593 Affected files irssi/src/module-formats.[ch] and
1594 irssi/src/silc/core/client_ops.c.
1596 * Format the multiple same nicknames also during JOIN and
1597 NICK_CHANGE notifys. Affected file is
1598 lib/silcclient/client_notify.c.
1600 * Do not print error on screen for invalid private message
1601 payload since it can come if someone is sending private
1602 messages with wrong key. Affected file
1603 lib/silccore/silcprivate.c.
1605 * Fixed multiple concurrent /PING crash. Affected file
1606 lib/silcclient/command.c.
1608 * Changed the wrong ID encoding. All IP addresses must be
1609 in MSB first order in encoded format. They were encoded
1610 wrong and was in LSB format. Affected files are
1611 silcd/serverid.c, lib/silcutil/silcutil.c.
1613 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1615 * Call the `connect' client operation through the scheduler
1616 in case of error. Affected file lib/silcclient/client.c.
1618 * Call the `failure' client operation even if the error
1619 occurred locally during a protocol. Affected file is
1620 lib/silcclient/protocol.c.
1622 * Added support of sending LIST command to router from normal
1623 server. This way normal server can get list of all channels
1624 in the network too. Fixed the channel list sending in the
1625 server too. Affected files are silcd/command.c, and
1626 silcd/command_reply.[ch].
1628 * Added silc_server_update_channels_by_server and
1629 silc_server_remove_channels_by_server. They are used during
1630 disconnection of primary router and in backup router protocol.
1631 Affected file silcd/server_util.[ch], silcd/server.c and
1632 silcd/server_backup.c.
1634 * Fixed channel adding to global list in IDENTIFY command
1635 reply in server. Affected file silcd/command_reply.c.
1637 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1639 * If the incoming packet type is REKEY or REKEY_DONE process
1640 that packet always synchronously. Fixes yet another MAC
1641 failed error on slow (dialup) connections. Affected file
1642 lib/silcclient/client.c and silcd/server.c.
1644 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Call check_version SKE callback for initiator too. Affected
1647 file lib/silcske/silcske.c.
1649 * Implemented fix for security hole found in the SKE that was
1650 fixed in the specification few days back; the initiator's
1651 public key is now added to the HASH value computation.
1652 Added backwards support for the old way of doing it too, for
1653 old clients and old servers. Affected file is
1654 lib/silcske/silcske.c.
1656 * Enabled mutual authentication by default in SKE. If initiator
1657 is not providing mutual authentication the responder will
1658 force it. This will provide the proof of posession of the
1659 private key for responder. The affected files are
1660 lib/silcclient/protocol.c and silcd/protocol.c.
1662 * Do not cache anymore the server's public key during SKE.
1663 We do mutual authentication so the proof of posession of
1664 private key is done, and if the server is authenticated in
1665 conn auth protocol with public key we must have the public
1666 key already. Affected file silcd/protocol.c.
1668 * Added new global debug variable: silc_debug_hexdump. If
1669 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1670 file lib/silcutil/silclog.[ch].
1672 * Fixed compilation warning due to char * -> const char *.
1673 Affected files lib/silcutil/silcnet.h, and
1674 lib/silccore/silcauth.[ch].
1676 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed CMODE command when new channel key was created. If
1679 the creation failed the old key was removed. Next time giving
1680 same command would crash the server since the old key was
1681 freed already. Affected file silcd/command.c.
1683 * Fixed the silc_server_announce_get_channels to not crash
1684 on reconnect. Affected file silcd/server.c.
1686 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Added silc_log_set_debug_string function to set a regex
1689 string to match for debug output. Only the function names,
1690 or filenames matching the given debug string is actually
1691 printed. This way it is possible to filter out those debug
1692 strings that user is not interested in.
1694 Fixed a bug in silc_string_regexify.
1696 Affected files lib/silcutil/silclog.[ch], and
1697 lib/silcutil/unix/silcunixutil.c.
1699 * Changed the -d options in both server and Irssi SILC client
1700 to take the debug string as argument. Affected files
1701 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1703 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Added silc_hash_babbleprint to create a Bubble Babble
1706 Encoded fingerprint. The encoding is developed by Antti
1707 Huima (draft-huima-babble-01.txt), and it creates human
1708 readable strings out of binary data. Affected file
1709 lib/silccrypt/silchash.[ch].
1711 * Print the babble print now in addition of fingerprint as well
1712 in Irssi SILC client. Affected files are
1713 irssi/src/fe-common/silc/module-formats.[ch],
1714 irssi/src/fe-common/silc/core/client_ops.c.
1716 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Fixed a security problem found in SKE. The initiator's
1719 public key too is now added to the HASH hash value creation
1720 which is signed by the responder to create the SIGN value.
1721 This will prevent anyone in the middle to lie to the responder
1722 about the initiator's public key. If this is done now, the
1723 man in the middle will get caught. Updated the protocol
1726 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Better installation directory handling. Configure module
1729 paths and other paths automatically to example_silc* files
1730 in doc/. A patch by toma.
1732 * Fixed compiler warning from MPI library, and from SILC RNG.
1735 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1736 It can be configured with ./configure. A patch by toma.
1738 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1740 * Find correct make to use in prepare-clean. A patch by
1741 toma. Affected file prepare-clean.
1743 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1745 * Added irssi variables use_auto_addr, auto_bind_ip,
1746 auto_bind_port and auto_public_ip.
1748 * Changed the interface for silc_client_send_key_agreement
1749 in lib/silcclient/silcapi.h
1753 irssi/src/silc/core/silc-core.c
1755 lib/silcclient/silcapi.h
1756 irssi/src/silc/core/silc-channels.c
1757 lib/silcclient/client_keyagr.c
1760 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Added silc_pkcs_public_key_compare to compare two
1763 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1765 * Check that the client who set the founder mode on the
1766 channel is the same client that is giving the founder
1767 mode to itself. It is done by comparing the saved public
1768 key (it is saved even in the authentication is passphrase).
1769 Affected file silcd/command.c.
1771 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1773 * Do not process packet for disconnected socket connection.
1774 Affected file lib/silccore/silcpacket.c.
1776 * Process the DISCONNECT packet through scheduler in the
1777 client library. Affected file lib/silcclient/client.c.
1779 * Fixed the silc_client_packet_parse to not to increase
1780 the packet sequence number if the conn->sock and the
1781 current socket connection is not same. This can happen
1782 for example during key agreement when the conn includes
1783 multiple socket connections (listeners). Affected file
1784 lib/silcclient/client.c.
1786 * The sender of the file transfer request now provides also
1787 the pointer (listener) for the key exchange protocol. If
1788 the listener cannot be created then it sends empty key
1789 agreement and lets the receiver provide the listener.
1791 Added `local_ip' and `local_port' arguments to the
1792 silc_client_file_send. If they are provided they are used,
1793 if not then it will attempt to find local IP address, if
1794 not found or bind fails then the remote client will provide
1797 Affected files are lib/silcclient/client_ftp.c and
1798 lib/silcclient/silcapi.h.
1800 * Extended the FILE SEND command to support defining the
1801 local IP and port for key exchange listener. They are
1802 optional. Affected file irssi/src/silc/core/silc-servers.c.
1804 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Defined to WHOIS command reply the sending of fingerprint
1807 of the client's public key (if the proof of posession of the
1808 corresponding private key is verified by the server).
1809 Updated to the protocol specification.
1811 * Added support of receiving the client's public key's
1812 fingerprint in command reply in client library. Affected
1813 file is lib/silcclient/command_reply.c, and
1814 lib/silcclient/idlist.[ch].
1816 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Do not send over 128 chars long nickname to the server
1819 in NICK command. Affected file lib/silcclient/command.c.
1821 * Do not send over 256 chars long channel names to the server
1822 in JOIN command. Affected file lib/silcclient/command.c.
1824 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Assure that silc_server_close_connection cannot be called
1827 twice for same socket context. Affected file is
1830 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Send error message to application if opening file for
1833 writing during file transfer fails. Affected file is
1834 lib/silcclient/client_ftp.c.
1836 Remove all file transfer sessions for a client that we're
1837 removing from ID cache.
1839 Affected file is lib/silcclient/client_ftp.c.
1841 * Fixed silc_net_addr2bin to return correct address. Affected
1842 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1844 * Fixed file transfer session removing on signoff notify.
1845 Affected file irssi/src/silc/core/silc-servers.c.
1847 * Added the SilcClientFileError to be returned in the monitor
1848 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1849 Affected file lib/silcclient/silcapi.h.
1851 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Fixed a crash in silc_client_ftp_free_sessions and
1854 silc_client_ftp_session_free_client. Affected file
1855 lib/silcclient/client_ftp.c.
1857 * Added `disabled' field in the SilcChannelEntry in the server
1858 to indicate if the server entry is disabled. Affected file
1859 silcd/idlist.h, silcd/command[_reply].c.
1861 * SILC server adds now /var/run/silcd.pid everytime it is
1862 started. Affected file silcd/silcd.c.
1864 * Added silc_server_packet_send_clients to send a packet to
1865 the provided table of client entries. Affected file
1866 silcd/packet_send.[ch].
1868 * Fixed a crash in client resolving in client_prvmsg.c in
1869 client library. Affected file lib/silcclient/client_prvmsg.c.
1871 * Do not actually remove the client directly from ID cache
1872 during SERVER_SIGNOFF, but invalidate it. This way we
1873 preserve the WHOWAS info for the client. Affected file
1874 silcd/server_util.c.
1876 * Fixed SERVER_SIGNOFF notify handling in the server. The
1877 server is now able to process incoming SERVER_SIGNOFF notify
1878 for a server that it doesn't even know about. It will remove
1879 the clients provided in the notify. Affected file
1880 silcd/packet_receive.c.
1882 * Check for partial packet in data queue after every packet that
1883 was found from the queue. Return and wait for more data if
1884 there is partial data in queue. Affected file is
1885 lib/silccore/silcpacket.c.
1887 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * Added SilcClietFileError enum to indicate error in
1890 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1891 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1892 Affected files lib/silcclient/silcapi.h and
1893 lib/silcclient/client_ftp.c.
1895 * Check that newsize in silc_buffer_realloc is larger than
1896 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1898 * Added better monitor of file transfers. It now monitors
1899 key agreement protocol during the file transfer too. Added
1900 error reporting too. Affected files
1901 irssi/src/silc/core/silc-servers.c,
1902 irssi/src/fe-common/silc/module-formats.[ch].
1904 * Wrote a help file for FILE command.
1906 * Added silc_rng_global_get_byte_fast to get not-so-secure
1907 random data as fast as possible. Random data is read from
1908 /dev/urandom if available and from the SILC RNG if not
1909 available. It is used in padding generation. Affected file
1910 lib/silccrypt/silcrng.[ch].
1912 * All packets in client library are now processed synchronously.
1913 Optimized packet processing a lot. Affected file
1914 lib/silcclient/client.c.
1916 * All server connection packets are processing synchronously
1917 now in server, to optimize packet processing. Affected file
1920 * Include files are installed now only in Toolkit distribution
1921 if make install is given. Affected files: all Makefile.am's.
1923 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Assure that silc_client_notify_by_server_resolve does not
1926 resolve the client information multiple times. If it cannot
1927 be found by the first it cannot be found at all. Affected
1928 file lib/silcclient/client_notify.c.
1930 * Fixed WHOWAS command reply calling. Affected file
1931 lib/silcclient/command_reply.c.
1933 * Removed all references to silc_idlist_get_client from the
1934 Irssi SILC client since that call is internal call used by
1935 the library. The Irssi SILC client will use now client
1936 retrieval functions found in silcapi.h.
1938 * Fixed a bug in resolving nickname info before sending
1939 private message. It used freed memory. Affected file
1940 irssi/src/silc/core/silc-servers.c.
1942 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Assure my_channels statistics cannot go negative in server.
1945 Affected files silcd/server.c, silcd/server_util.c.
1947 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1951 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Win32 Toolkit changes. Affected files
1954 win32/silc.dsw, win32/libsilc/libsilc.def,
1955 win32/libsilcclient/libsilc.def,
1956 lib/silcutil/silcutil.c, and
1957 lib/sftp/sftp_fs_memory.c.
1959 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Added silc_net_localip to return local host's IP address.
1962 Affected file lib/silcutil/silcnet.[ch].
1964 * If key exchange or rekey protocol is active for a connection
1965 parse all packets syncronously since there might be packets
1966 in packet queue that we are not able to process without first
1967 processing packets before them. Affected file silcd/server,
1968 lib/silcclient/client.c.
1970 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1971 whether library should continue processing the packet.
1972 Affected file lib/silccore/silcpacket.h.
1974 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1975 SilcSFTPMonitorData to SFTP server to monitor various
1976 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1977 lib/silcsftp/sftp_server.c.
1979 * Added silc_file_size to return file size. Affected file
1980 lib/silcutil/silcutil.[ch].
1982 * Implemented the file transfer support for the client library.
1983 Added preliminary support for simple client to client one-file
1984 transmission. Affected file lib/silcclient/client_ftp.c,
1985 lib/silccilent/client.[ch].
1987 * Added new local command FILE to the Irssi SILC Client.
1988 It is used to perform the file transfer. It has subcommands
1989 SEND, RECEIVE, SHOW and CLOSE. Affected files
1990 irssi/src/silc/core/client_ops.c,
1991 irssi/src/silc/core/silc-server.[ch].

2000 * Renamed silc_file_read and silc_file_write to functions
2001 silc_file_readfile and silc_file_writefile. Added function
2002 silc_file_open and silc_file_close. Affected files
2003 lib/silcutil/silcutil.[ch].
2005 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Resolve the client info when received private message or
2008 channel message for a client which nickname we don't know.
2009 Affected files lib/silcclient/client_prvmsg.c and
2010 lib/silcclient/client_channel.c.
2012 * Do not crash in /KEY if client is not connected. Affected
2013 file irssi/src/silc/core/silc-channels.c.
2015 * Added SilcClientStatus field to the SilcClientEntry in the
2016 lib/silcclient/idlist.h.
2018 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2019 is incomplete and is being resolved, it won't be resolved
2022 Make sure also that USERS command reply does not resolve
2023 twice information. Affected file is
2024 lib/silcclient/command_reply.c.
2026 Make sure that silc_client_get_clients_by_list does not
2027 resolve twice same information.
2029 * Check for valid client->id in the silc_server_free_client_data.
2030 Affected file silcd/server.c.
2032 * Fixed /GETKEY nick@server not to crash if the server entry
2033 is not found. Affected file lib/silcclient/command.c.
2035 * Fixed the silc_server_check_cmode_rights to check the
2036 requested modes correctly. Affected file silcd/command.c.
2038 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Better checks for non-printable chars in nick added.
2041 Affected file silcd/command.c.
2043 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Call the silc_server_udpate_servers_by_server in the
2046 primary router that comes back online in the backup resuming
2047 protocol. Otherwise it routes packets wrong. Affected file
2048 silcd/server_util.[ch], silcd/server_backup.c.
2050 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2052 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2053 lib/silcutil/silcbuffmt.[ch].
2055 * Redefined the SILC packet header to include the padding
2056 length. Affected file lib/silccore/silcpacket.[ch].
2058 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2059 length for maximum padding up to 128 bytes). Affected
2060 file lib/silccore/silcpacket.h.
2062 * Removed all backwards support for old 0.5.x MAC thingies.
2063 The SILC packet header change makes it impossible to be
2064 backwards compatible.
2066 * Send the ENDING packet with timeout in the backup resuming
2067 protocol. This is to assure that all routers has connected
2068 to the primary router. Affected file silcd/server_backup.c.
2070 * Changed the RNG to take the first IV from random data. It
2071 used to take it from zero actually. Changed the RNG also
2072 to use /dev/urandom during session. /dev/random is used
2073 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2075 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Changed the SILC packet header to have the first two bytes
2078 (the packet length) encrypted. Affected files aroung the
2079 code tree, lib/silccore/silcpacket.[ch]. Removed the
2080 SilcPacketCheckDecrypt callback. It is not needed anymore
2081 since the silc_packet_receive_process will determine now
2082 whether the packet is normal or special.
2084 * Implemented the unidirectional MAC keys. Affected files
2085 lib/silcske/silcske.c, silcd/protocol.c and
2086 lib/silcclient/protocol.c.
2088 * Implemented the packet sequence number to the MAC computation.
2089 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2090 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2091 lib/silcclient/protocol.c.
2093 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Allow backup router to announce servers. All servers
2096 announced by backup router are added to the global list
2097 automatically. Update hte server's socket to our primary
2098 router also when backup router announces a server.
2099 Affected file silcd/packet_receive.c.
2101 * Do not update the client->router in the function
2102 silc_server_udpate_clients_by_server if the client is on
2103 global list. We might fail to find any specific server
2104 for locally connected clients and local cell clients. They
2105 should still use the `from' and not `to' as client->router.
2106 This fixes backup router resuming protocol. Affected file
2107 silcd/server_util.c.
2109 * Decrease channel statistics count only if the channel
2110 deletion worked. Affected files are silcd/server.c and
2111 silcd/server_util.c.
2113 * Added silc_server_update_servers_by_server to update origin
2114 of all server entries. Used during backup router protocol.
2115 Affected files silcd/server_util.[ch], silcd/server.c. and
2116 silcd/backup_router.c.
2118 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2119 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2120 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2121 lib/silccrypt/silchmac.c.
2123 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Assure that router cannot reroute the same channel message
2126 to the sender. Affected file silcd/packet_receive.c.
2128 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Made better checks that the channel message is not sent
2131 to the router it came from. Affected file is
2132 silcd/packet_send.c. Fixed memory leak too.
2134 * Announce informations for incoming router connection, but
2135 only after checking if it is replaced by backup router.
2136 Affected file silcd/packet_receive.c.
2138 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Fixed the backup resuming protocol to work in multiple
2141 router environment. Affected file silcd/server_backup.c.
2143 * Route packet only to one router in the function
2144 silc_server_packet_send_to_channel. Affected file is
2145 silcd/packet_send.c.
2147 * Fixed silc_server_send_notify_dest to set the broadcast
2148 flag. Fixed the silc_server_send_notify_topic to actually
2149 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2150 Affected file silcd/packet_send.c.
2152 * Changed the SFTP Filesystem interface. Changed the
2153 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2154 the filesystem operation function. The SilcSFTPFilesystem
2155 is now a context that is allocated by all filesystem allocation
2156 functions and it already includes the operations structure
2157 and filesystem specific context. It is given as argument
2158 now to the silc_sftp_server_start. This made the interface
2159 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2160 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2162 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2164 * Changed the backup router adding and getting interfaces
2165 in the server. The router that will be replaced by the
2166 specified backup router is now sent as argument. Affected
2167 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2170 * Added silc_net_addr2bin_ne to return the binary form of
2171 the IP address in network byte order. Affected files
2172 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2174 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Check for existing server ID in silc_server_new_server
2177 and in silc_server_connect_to_router_final and remove the
2178 old entry if it exists. Affected file silcd/packet_receive.c,
2181 * Send the channel message always to only one router, either
2182 in upstream or downstream. Affected file is
2183 silcd/packet_send.c.
2185 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Wrote the definition of the backup resuming protocol to the
2188 protocol specification.
2190 * Removed one redundant channel key generation from normal
2191 server during joining procedure. Removed one redundant
2192 channel key sending from server to router during joining
2193 procedure. Affected file silcd/command.c.
2195 * Made minor bugfixes to the backup router resuming protocol.
2196 Affected file silcd/server_backup.c, server.c.
2198 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Added --disable-asm configuration option. Affected files
2201 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2204 * Implemented the backup resuming protocol that is used to
2205 resume the primary router position in the cell after the
2206 primary router comes back online. Affected files
2207 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2208 and silcd/server_util.[ch].
2210 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Sleep two (2) seconds after sending QUIT command to server.
2213 Affected file lib/silcclient/command.c.
2215 * Assure that if outgoing data buffer is pending do not force
2216 send any data. Affected file silcd/packet_send.c.
2218 * Assure that if outgoing data buffer is pending do not force
2219 send any data. Affected file lib/silcclient/client.c.
2221 * Implemented the backup router support when the primary router
2222 goes down. The servers and routers can now use the backup
2223 router as new primary router without loosing connectivity.
2225 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2228 in the server to indicate disabled entry. All data read
2229 from the connection will be ignored and no data is sent
2230 for entry that is disabled. Affected files are
2231 silcd/idlist.h, silcd/server.c.
2233 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2235 * Created SFTP client and server test programs in the
2236 lib/silcsftp/tests directory.
2238 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Implemented memory filesystem (virtual filesystem) for
2241 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2244 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Implemented the SFTP (SSH File Transfer Protocol) to the
2247 lib/silcsftp. It includes SFTP client and SFTP server
2250 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2252 * Moved lib/silccore/silcprotocol.[ch] to the
2253 lib/silcutil library.
2255 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2256 take variable argument list pointer as argument. Affected
2257 file lib/silcutil/silcbuffmt.[ch].
2259 * Added silc_buffer_set function that is used to set data
2260 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2261 Affected file lib/silcutil/silcbuffer.h.
2263 * Changed various routines in the core library to use the new
2264 silc_buffer_set instead of allocating new buffer only for
2267 * Added 64-bit value formatting and unformatting support to the
2268 silc_buffer_[un]format routines. Affected file is
2269 lib/silcutil/silcbuffmt.[ch].
2271 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2272 to includes/bitmove.h.
2274 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Fixed channel user mode saving in client library. Affected
2277 file lib/silcclient/command[_reply].c.
2279 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Defined the file transfer to the SILC Protocol. Added
2282 new packet type SILC_PACKET_FTP and defined File Transfer
2283 Payload. The mandatory file transfer protocol is SFTP
2284 (SSH File Transfer Protocol). Affected file in addition
2285 of the internet draft is lib/silccore/silcpacket.h.
2287 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2288 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2289 is used as part of backup router protocol when the primary
2290 router of the cell is back online and wishes to resume
2291 the position as primary router.
2293 * Redefined the MAC generation keys in the protocol. The
2294 same key is not used anymore in both direction. Both
2295 direction will now use different keys for sending and
2296 receiving. This fixes a potential security flaw. This
2297 change causes incompatibilities in the protocol.
2299 * Redefined also the MAC computation from the packet.
2300 An packet sequence number is now added to the MAC
2301 computation. This prevents possible replay attacks against
2302 the protocol. This change too causes incompatibilities
2305 Added `sequence' field to the SilcPacketContext to hold
2306 the current sequence number for the packet.
2308 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2310 * Added `created' field to the SilcIDListData in the file
2311 silcd/idlist.h to indicate the time when the entry was
2314 * Added `created' field to the SilcChannelEntry too. Affected
2315 file silcd/idlist.h.
2317 * Added `creation_time' aguments to all the announcement functions
2318 in the server. If it is provided then only the entries that
2319 was created after the provided time frame are actually
2320 announced. Affected file silcd/server.[ch].
2322 * The protocol says that the Channel ID's IP address must be
2323 based on the router's IP address. Added check for this in
2324 the silc_server_new_channel when processing incoming New Channel
2325 Payload. Affected file silcd/packet_receive.c.
2327 * Print out the correct version with --version in SILC client.
2328 Affected file irssi/src/silc/core/silc-core.c.
2330 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Fixed WHOWAS command to check for completnes of the client
2333 entry always, not just when the command is coming from client.
2334 Affected file silcd/command.c.
2336 * Added new function silc_server_packet_queue_purge to purge the
2337 outgoing data queue to the network. After the function returns
2338 it is guaranteed that the outgoing packet queue is empty.
2339 Affected file silcd/packet_send.[ch].
2341 * Purge the outgoing packet queue in the rekey protocol's final
2342 callback to assure that all rekey packets go to the network
2343 before quitting the protocol. Affected file silcd/server.c.
2345 * Added silc_client_packet_queue_parse as similar function as
2346 in server to the client library. The affected file is
2347 lib/silcclient/client.c.
2349 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Splitted silcd/server.c and created silcd/server_util.[ch]
2352 for utility functions.
2354 * Added new socket flag SILC_SF_DISABLED to indicate that the
2355 connection is open but nothing can be sent to or received from
2356 the connection. Affected file lib/silcutil/silsockconn.[ch].
2357 The checking for disabled socket is checked in the low level
2358 silc_socket_write and silc_socket_read functions.
2360 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Allow only nicknames and channel names that fits into the
2363 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2365 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * When processing JOIN command reply in server check that if
2368 the channel exists in our global list we'll move it the local
2369 list. Affected file silcd/command_reply.c.
2371 * Fixed the check whether client is joined on the channel already
2372 in JOIN command. Affected file lib/silcclient/command.c.
2374 * Fixed the JOIN command reply to check whether the channel
2375 already exists. Affected file lib/silcclient/command_reply.c.
2377 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Added silc_ske_status_string to map the SKE error numbers
2380 to readable strings. The affected files are
2381 lib/silcske/silcske[_status].[ch].
2383 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Do not show the private channels on the WHOIS channel list
2386 as it is not allowed by the protocol. The affected file is
2389 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Assure that the packet length digged from the actual packet
2392 is something sensible in the silc_packet_decrypt_rest_special
2393 in lib/silccrypt/silcpacket.c.
2395 * Free and NULL the allocated pointer in silc_hmac_alloc if
2396 the HMAC allocation fails. The affected file is
2397 lib/silccrypt/silchmac.c.
2399 * Print the selected security properties to the log files in
2400 the server. Affected file silcd/protocol.c.
2402 * Add SKE's reference counter even if calling the completion
2403 callback manually. Otherwise it goes negative, although it
2404 does not cause any problems. The affected file is
2405 lib/silcske/silcske.c.
2407 * Remove the client entry with short timeout after giving the
2408 KILL command. Affected file lib/silcclient/command.c.
2410 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2411 case all found clients are already disconnected (WHOWAS would
2412 found them) in the server. Affected file silcd/command.c.
2414 * Update the last_receive (time of last data received) to be
2415 updated only when received private or channel message so that
2416 the idle time showed in WHOIS makes more sense.
2418 * Added boolean field `valid' in to the SilcClientEntry in the
2419 client library to indicate whether the entry is valid or not.
2420 This fixes the nickname change bug on channel when changing
2421 the nickname to be same than the old (like nick to Nick) the
2422 nickname formatter doesn't set the new nick anymore to Nick@host.
2423 Affected file lib/silcclient/idlist.[ch].
2425 * Now actually fixed the nickname changing on disconnection.
2426 Added new function silc_change_nick to the Irssi SILC Client.
2427 Affected file irssi/src/silc/core/client_ops.c,
2428 irssi/src/silc/core/silc-nicklist.[ch].
2430 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Check that the public key exists in the GETKEY command before
2433 trying to encode it. Affected file silcd/command.c.
2435 * Print some notifications on received public keys with GETKEY
2436 command in the Irssi SILC Client. Affected files are
2437 irssi/src/fe-common/silc/module-formats.[ch],
2438 irssi/src/silc/core/client_ops.c.
2440 * Use IDENTIFY command to resolve the server information in the
2441 GETKEY command instead of INFO command. Affected file
2442 lib/silcclient/command.c.
2444 * All command reply functions in the client library now calls
2445 the pending command reply callbacks even if an error has
2446 occurred. The server has done this a long time and now it was
2447 time to move the client library to this as well. Now all
2448 errors can be delivered back to the pending command reply
2449 callbacks if necessary. Affected files are
2450 lib/silcclient/command[_reply].[ch].
2452 * Change the nickname on disconnection back to the username
2453 because in reconnect the server will enforce it to it anyway.
2454 Affected file irssi/src/silc/core/silc-servers.c.
2456 * Fixed a config file parsing bug in the Irssi SILC client.
2457 Affected file irssi/src/silc/core/clientconfig.c.
2459 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * When printing the channel mode on JOIN, verify that the
2462 channel key and channel's HMAC are valid. Affected file
2463 irssi/src/silc/core/client_ops.c.
2465 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2468 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2469 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2471 * Removed channel key rekey task deleting from the function
2472 silc_server_save_channel_key. Affected file silcd/server.c.
2473 Added explicit timeout task context instead that is used to
2474 delete the task if we are registering a new task before the
2475 new task has elapsed.
2477 * When channel key rekey occurs the client library now saves
2478 the old channel key for a short period of time (10 seconds) and
2479 is able to use it in case some is still sending channel
2480 messages encrypted with the old key after the rekey. Affected
2481 file lib/silcclient/[idlist.h|client_channel.c].
2483 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Added check to the silc_server_new_id_real to not accept
2486 new ID if it is the sender's own ID. Affected file is
2487 silcd/packet_receive.c.
2489 * Assure that we do not announce ourself or the one we've
2490 sending our announcements when we're router and are announcing
2491 servers to our primary router. Affected file silcd/server.c.
2493 * Fixed silc_server_command_identify_check_client to assemble
2494 correct WHOIS packet. It send corrupted WHOIS packet and
2495 caused problem with router to router connections. Affected
2496 file silcd/command.c.
2498 Fixed also silc_server_command_whois_check the same way
2499 as for the IDENTIFY command.
2501 * Added new SilcIDListStatus to the server in the SilcIDListData
2502 structure. The status now includes the current status of
2503 the entry (like registered, resolved etc.). Affected file
2504 silcd/idlist.[ch]. Defined a bunch of different status types
2505 as well. This replaced the old boolean registered field as well.
2507 Added resolve_cmd_ident field to the SilcClientEntry structure
2508 too so that if the entry is for example being resolved so
2509 another command may attach to the same pending command reply
2510 without requiring to resolve the same entry again. This concept
2511 should optimize the WHOIS and the IDENTIFY resolving under
2512 heavy load by taking away unnecessary resolving for entries
2513 that are being resolved already.
2515 Added support for adding multiple pending commands for one
2516 command idenfier. Affected file silcd/command[_reply].[ch].
2518 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2519 before deleting the data. Otherwise the hash table will have
2520 freed data in comparison functions. Affected file is
2521 silcd/command_reply.c.
2523 * Fixed silc_idlist_replace_client_id to add the new entry to
2524 the cache with NULL nickname. Otherwise there will be invalid
2525 memory as the nickname after the nickname is freed. Affected
2526 file silcd/packet_receive.c.
2528 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2529 saved into wrong slots because the previous number of entries
2530 was not taken into account. Affected file silcd/idlist.c.
2531 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2533 * If we are router and we receive JOIN notify to a channel that
2534 does not have any users then notified client is marked as the
2535 channel founder, as it is it. The affected file is
2536 silcd/packet_receive.c
2538 * Added to the extended hash table API's table_del_*ext functions
2539 the destructor as argument too, so that the caller can decide
2540 which destructor to use or whether to use destructor at all.
2541 Affected file lib/silcutil/silchashtable.[ch].
2543 * Fixed ID Cache purging. It actually deleted the entries from
2544 the hash table after the data was freed. The hash table ended
2545 up comparing freed memory. The affected file is
2546 lib/silccore/silcidcache.c.
2548 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Fixed Irssi SILC client's KILL command's HELP syntax.
2552 * The USERS command now resolves the detailed user information
2553 if the userinfo field is missing. Affected file is
2554 lib/silcclient/command_reply.c.
2556 * Do not print error in silc_file_read if the read file does
2557 not exist. Just silently return NULL. Affected file is
2558 lib/silcutil/silcutil.c.
2560 * Fixed the silc_log_output to not wine about NULL filename
2561 and to not create some bogus " " filename. Affected file is
2562 lib/silcutil/silclog.c.
2564 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2566 * Fixed various printing bugs on the user interface in the
2567 Irssi SILC Client. Minor changes that were forgotten from
2570 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Fixed the configure.in.pre and the compilation and distribution
2573 environment to support the new autoconf 2.52. That version is
2574 now required to compile the CVS trunk.
2576 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2579 to generally parse user@fqdn format strings. Affected file
2580 lib/silcutil/silcutil.c.
2582 * Added nickname_format and nickname_force_format fields to the
2583 SilcClientParams structure. The first one defines the format
2584 for the nicknames that the library will enforce if the receives
2585 multiple same nicknames. The second one is boolean value and
2586 can be used to force the library to always enforce the format
2587 to the nicknames regardles whether there are multiple nicknames
2588 or not. This configurable formatting was employed to flexibly
2589 support accessing multiple nicknames from the user interface.
2590 The userinterface can now set the nicknames to what ever format
2591 they prefer. Affected file lib/silcclient/silcapi.h.
2593 Added function silc_client_nickname_format to the file
2594 lib/silcclient/idlist.c. It performs the nickname formatting.
2596 Added new field `hostname´ to the SilcClientEntry context.
2597 It holds the hostname of the client. Affected file is
2598 lib/silcclient/idlist.h.
2600 * Irssi SILC Client sets the nicknames in nick@hostn format.
2601 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2602 irssi/src/silc/core/silc-core.c.
2604 The WHOIS printing now also shows both the real nickname and
2605 the formatted nickname so that user knows how to access the
2606 user if there are multiple same nicknames cached. Affected
2607 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2608 printing formatting too to take the hostname now as a separate
2609 argument. The Affected file is
2610 irssi/src/fe-common/silc/modules-formats.[ch].
2612 * Changed the silc_client_get_clients_local to accept the formatted
2613 nickname as argument. It accepts the real nickname too but the
2614 formatted nickname can be used to find the true entry from
2615 multiple entries. Affected file lib/silcclient/silcapi.h and
2616 lib/silcclient/idlist.c.
2618 * Added nickname_format_parse field to the SilcClientParams.
2619 It is a callback function provided by the application to parse
2620 the nickname out of the formatted nickname string. The library
2621 calls it to get the nickname from the formatted string. Since
2622 the application generally knows better the format of the nickname
2623 string it parses it instead of the library, even though library
2624 encodes the formatted string. If the callback function is not
2625 provided then the library will use the string as is. The
2626 affected file is lib/silcclient/silcapi.h.
2628 * All the nickname strings passed to the client library in
2629 commands are now expected to be formatted nickname strings.
2630 If the command does not support the formatted nickname string
2631 it will assume that the sent string is the actual nickname.
2632 Affected file lib/silcclient/command.c.
2634 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Added public key authentication support to OPER and SILCOPER
2637 commands in the client library. Affected file is
2638 lib/silcclient/command.c.
2640 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2642 * Changed the get_auth_methdod client operation to be asynchronous.
2643 It can be async if the application resolves the authentication
2644 method from the server during the negotiation. Added new
2645 SilcGetAuthMeth completion callback that the application will
2646 call after resolving the authentication method.
2648 Added function silc_client_request_authentication_method that
2649 the application can use to resolve the authentication method
2650 from the server. Added also SilcConnectionAuthRequest callback
2651 that the library will call after the server has replied. The
2652 application can call this function if it does not know the
2653 current authentication method.
2655 Affected files are lib/silcclient/client.c and
2656 lib/silcclient/silcapi.h.
2658 * The Irssi SILC client now automatically resolves the authentication
2659 method incase any configuration information is not present (and
2660 currently there never is). The affected file is
2661 irssi/src/silc/core/client_ops.c.
2663 * Fixed public key authentication from the client library.
2664 Affected file lib/silcclient/protocol.c. Changed also the
2665 protocol specification about the public key authentication in
2666 the connection authentication protocol. The actual data to be
2667 signed is now computed with a hash function before signing.
2669 * Fixed the public key authentication from the server as well.
2670 Affected file silcd/protocol.c.
2672 * Removed the mlock()'s from the memory allocation routines.
2673 Affected file lib/silcutil/silcmemory.c. The ./configure does
2674 not check anymore for the mlock(). Affected file is
2677 * Fixed USERS command in server to allow the execution of the
2678 command for private and secret channels if the client sending
2679 the command is on the channel. Affected file silcd/command.c.
2681 * Fixed silc_client_get_clients_local to return the clients
2682 count correctly. It could return wrong value. Affected file
2683 lib/silcclient/idlist.c.
2685 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2687 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2688 types. The assembler optimizations seemed not to like 64-bit
2689 data types. The assmebler optimizations thus are now enabled
2690 also for BSD systems as opposed to only enable them for Linux.
2692 * Do not check for threads at all on BSD systems. Affected
2693 file configure.in.pre.
2695 * Removed -n and -h options from the Irssi SILC Client since
2696 they are not used in silc.
2698 * Fixed the prime generation to assure that the first digit
2699 of the generated random number is not zero since our conversion
2700 routines does not like number strings that starts with zero
2701 digit. If zero digit is seen the random number is regenerated.
2702 This caused some corrupted RSA keys when the zero first digit
2703 was met. Affected file lib/silcmath/silcprimegen.c.
2705 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Fixed WIN32 configuration in the ./configure script.
2708 Fixed to include xti.h on environments that has it.
2709 Patches by Carsten Ilchmann and andrew.
2711 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Changed the silc_id_create_client_id to be collision
2714 resistant. It is now assured that there cannot be created
2715 two same client ID's. I suspect that some weird bugs in
2716 the server were actually caused by duplicate Client IDs.
2717 Affected file silcd/serverid.[ch]. A router receiving
2718 new ID now also assures and informs the sending server
2719 if the ID caused collision.
2721 * Changed the silc_id_create_channel_id to also assure that
2722 there are no collisions.
2724 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Statement about ignoring the Mutual Authentication flag when
2727 performing rekey with PFS was a bit misleading. It is ignored
2728 if it was set in the initial negotiation, it cannot be even
2729 set in the rekey. Fixed in the ke-auth draft. Started the
2730 new versions of the protocol drafts in the doc/.
2732 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Fixed a bug in silc_client_command_identify_save when saving
2735 new channel information. The channel name was no duplicated
2736 and caused crash on exit. Affected file is
2737 lib/silcclient/command_reply.c.
2739 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Fixed the getkey command handling in the server. Send just
2742 empty OK reply to the sender if the key could not be fetched
2743 (but everything else was ok, like the key just was not available).
2744 Changed the public key parameter to optional in the protocol
2745 specs so that empty OK reply can be sent. Affected file
2748 Added a message to Irssi SILC client to tell to user if the
2749 server did not return a public key.
2751 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Fixed a channel key regeneration bug. It registered new
2754 timeout tasks exponentially until all system resources were
2755 used. Affected file silcd/server.c.
2757 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Added the SILC Document generator to the scripts/silcdoc.
2760 It can be used to generate the Toolkit Reference Manual out
2761 of the source tree. Internally it will also use the RoboDoc
2762 generator now imported in util/robodoc.
2764 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Added couple of return's in rekey protocol if error orccurred
2767 during the protocol. The execution must be terminated.
2768 Affected file silcd/protocol.c. Also, terminate the protocol
2769 always with timeout.
2771 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * The client's Client ID was created initally from the wrong
2774 nickname (it could have been in format nick@host) in the
2775 silc_server_new_client. Affected file silcd/packet_receive.c
2777 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2779 * Added some SILC_LOG_ERROR's to various error conditions
2780 if client could not be added to ID cache. Affected files
2781 silcd/packet_receive.c and silcd/server.c.
2783 * When client's sock->user_data is freed, NULL also the
2784 client->router and client->connection pointers. Added check
2785 for these pointers being NULL to various places around the
2786 code. Affected file silcd/server.c.
2788 * Added client->data.registered == TRUE checks to various
2789 places around the code to assure that unregistered client's
2790 are not handled when it is not allowed. Affected file
2793 * Added `bool registered' fields to all
2794 silc_idlist_[server|client]_get_* routines to indicate whether
2795 the fetched client needs to be registered or not. Affected
2796 file silcd/idlist.[ch].
2798 * Add your own entry as registered to the ID cache in the
2799 server. Affected file server.c.
2801 * Fixed a bug in silc_server_new_server. The SilcServer was
2802 set as the new server's context instead of SilcServerEntry.
2803 This naturally caused some weird bugs.
2805 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2807 * Do not delete the channel rekey task when adding it
2808 for in silc_server_create_channel_key.
2810 * Changed the silc_server_create_channel_key to return
2811 TRUE or FALSE to indicate the success of the channel key
2814 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * Fixed MSVC++ project files and added missing files to
2817 Makefiles under win32/.
2819 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Do not add TCP_NODELAY flag if the operating system
2822 does not have it defined. Affected files are
2823 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2825 * Fixed buffer overflow from Irssi SILC Client. Affected
2826 file irssi/src/fe-common/core/themes.c.
2828 * Fixed double free in client library in the file
2829 lib/silcclient/client.c when disconnecting from server.
2831 * Applied double free patch from cras to Irssi SILC client.
2832 Affected files irssi/src/core/[modules/expandos].c
2834 * Fixed the disconnection handling to Irssi SILC Client.
2835 The application must call silc_client_close_connection
2836 in ops->connect client operation in case of failure of
2837 the connection. Affected file is
2838 irssi/src/silc/core/client_ops.c.
2840 * Do not set sock->protocol to NULL in the function
2841 silc_client_close_connection after executing the protocol's
2842 final callback since the sock might not be valid anymore.
2843 Affected file lib/silcclient/client.c.
2845 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2847 * Do not enable SILC_THREADS if the linking with libpthread
2848 did not happen. Affected file configure.in.pre.
2850 * Added notion to protocol specification that server must
2851 verify the sent authentication payload with CMODE when
2852 setting the channel founder key. Implemented it to the
2853 server. Affected file silcd/command.c.
2855 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Added _EXTRA_DIST SILC distribution variable to the
2858 distributions file. It is used to conditionally add extra
2859 files or directories to the specific distribution. Affected
2860 files ./prepare, Makefile.am.pre and distributions.
2862 Removed the `_' from the start of the distribution names.
2865 * Added README.WIN32 for instructions to compile the Toolkit
2868 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Fixed a double free in disconnection in the server. Affected
2871 file is silcd/server.c.
2873 * Fixed the lib/silcske/groups.c to work now also with GMP
2874 MP library. The string conversion did not work when using
2875 specific base and the base is indicated in the string as well.
2877 * Created win32/ directory which now includes MSVC++ specific
2878 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2879 It will appear only in the toolkit distribution
2881 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Changed the key material distribution function in case when
2884 the hash output is too short. The data is now concatenated
2885 a bit differently than it used to. Made the change to the
2886 SKE protocol specification.
2888 * Added better GMP detection to configure.in.pre. A patch
2891 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Fixed a minor bug in SKE that might cause some problem on
2894 some platforms. Affected file lib/silcske/silcske.c.
2896 * Added the cookie checking for initiator in the SKE. It checks
2897 that the responder returns the sent cookie unmodified. The
2898 affected file is lib/silcske/silcske.c. Added new SKE
2899 error type INVALID_COOKIE that can be sent during the
2900 negotiation. Fixed some memory leaks as well.
2902 * Added the "invalid cookie" error message to Irssi SILC client's
2905 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Added `task_max' field to the SilcClientParams to indicate
2908 the maximum tasks the scheduler can handle. If set to zero,
2909 default values are used. Affected file lib/silcclient/silcapi.h.
2911 * Fixed memory leaks in silc_client_close_connection. Affected
2912 file lib/silcclient/client.c.
2914 * Added silc_client_del_client_entry to client library to free
2915 all memory of given client entry. Affected file is
2916 lib/silcclient/idlist.[ch].
2918 * Added new functions silc_client_del_channel and
2919 silc_client_del_server to delete channel and server entries.
2920 Affected file lib/silcclient/[silcapi.h/idlist.c].
2922 * Removed silc_client_del_client_by_id from silcapi.h.
2924 * Fixed the INFO command to return the server's own info
2925 correctly when querying by Server ID. Affected file is
2928 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2930 * Removed the non-blocking settings in WIN32 code in the
2931 silc_sock_[read/write] and added SleepEx instead. Affected
2932 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2933 of input data is now checked with FIONREAD and ioctlsocket.
2935 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2937 * Call silc_schedule_task_del_by_context in the
2938 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2939 Affected file lib/silccore/silcprotocol.c.
2941 * Call silc_protocol_cancel for active protocols in the
2942 silc_server_close_connection if the funtion
2943 silc_server_free_sock_user_data has not been called.
2944 Affected file silcd/server.c.
2946 * Generic tasks cannot be deleted using the del_by_fd
2947 task deleting function since generic tasks does not match
2948 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2950 * Added a notion to SILCOPER help file that the SILCOPER works
2951 only on router server, not on normal server.
2953 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Added for WIN32 support for the new scheduler as well.
2956 Affected file lib/silcutil/win32/silcwin32schedule.c.
2958 * Fixed the SHA1 implementation to work on various platforms.
2960 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2963 API. It is part of the scheduler now. Everything else is
2964 as previously but some functions has changed their names.
2965 Checkout the lib/silcutil/silcschedule.h for the interface.
2966 Updated all applications to use the new interface. Affected
2967 files are lib/silcutil/silcschedule.[ch].
2969 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * Found a bug in the SKE implementation. The HASH value,
2972 specified by the protocol, was not computed correctly. The
2973 public key of the responder was not added to the computation
2974 even though it is mandatory. Affected file lib/silcske/silcske.c.
2975 This unfortunately causes incompatibilities with older
2976 clients and servers.
2978 * Added WIN32 specific network init and uninit functions:
2979 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2980 the Winsock2. Affected file lib/silcutil/silcnet.h and
2981 lib/silcutil/win32/silcwin32net.c.
2983 * Set the socket always to nonblocking mode on WIN32 after
2984 reading data or writing data. Affected file is
2985 lib/silcutil/win32/silcwin32sockconn.c.
2987 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Fixed various compilation problems under WIN32. Affected
2990 files lib/silcutil/win32/silcwin32thread.c and
2991 lib/silcutil/win32/silcwin32schedule.c.
2993 * Removed all _internal.h #includes from public header
2994 files. Internal headers must never be included from
2997 Removed also the lib/silcske/payload_internal.h file.
2999 * All include files that may be needed (public and some others
3000 included by the public headers) by application developers are
3001 now copied to the ./includes directory. It does not copy any
3002 internal headers. Affected file Makefile.defines.pre and all
3003 Makefile.am's under lib/ and subdirs.
3005 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Do not change the ~/.silc directory's permissions automatically.
3008 Affected file irssi/src/silc/core/clientutil.c.
3010 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Do not cancel the protocol in silc_server_close_connection
3013 it might cause recursion. Now cancelled in the function
3014 silc_server_free_sock_user_data. Affected file silcd/server.c.
3016 * Fixed the silc_server_remove_clients_by_server to regenerate
3017 the channel keys correctly finally. Added also new function
3018 silc_server_remove_clients_channels to actually do it.
3019 Affected file silcd/server.c.
3021 * Fixed the silc_server_new_channel to not crash by giving
3022 wrong router to the new channel. Affected file is
3023 silcd/packet_receive.c.
3025 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3028 which is given as argument to the silc_client_alloc now.
3029 It can be used to configure the client and set various parameters
3030 that affect the function of the client.
3032 * The USERS command in server did not check whether the channel
3033 is private or secret. Affected file silcd/command.c.
3035 * Added new argument to the USERS command in protocol specification.
3036 The USERS command now can take the channel name as argument
3037 as well. Added support for this in client and server and
3038 updated the protocol specs.
3040 * Completed the GETKEY command in client. It can be now used
3041 to fetch also servers public key not only some clients.
3042 Affected files lib/silcclient/command[_reply].c.
3044 * Added silc_client_get_server to return server entry by the
3045 server name. Affected files lib/silcclient/silcapi.h and
3048 * Redefined the IDENTIFY command in protocol specification to be
3049 more generic. It now can be used to query information about
3050 any entity in the SILC Network, including clients, servers and
3051 channels. The query may be based either the entity's name
3052 or the ID. Added support for this in both client and server.
3054 Affected files silcd/command.c and lib/silcclient/command.c
3055 and command_reply.c.
3057 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3058 the _from_client and _from_server functions. Affected file
3061 * Added silc_client_get_channel_by_id_resolve to the file
3062 lib/silcclient/silcapi.h to resolve channel information by
3063 its ID. Added also silc_client_get_channel_by_id that
3064 does not resolve it from the server.
3066 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Added SilcServerEntry context into the client library
3069 to represent one server. The INFO command now allocates
3070 these to save the resolved server info. For now on the
3071 client library will also keep information about servers,
3072 connected and resolved with INFO.
3074 The INFO command now allocates the SilcServerEntry context
3075 and saves the server info there. The COMMAND_REPLY in
3076 the INFO now returns the parameters to application in
3077 same order as defined in the protocol specification.
3079 The entries are cached in the client->server_cache.
3081 * The INFO command is now issued after received the Client ID
3082 from the server. Affected file lib/silcclient/client.c.
3084 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3085 to the application as the mode changer might be server.
3086 It is guaranteed that NULL is not returned anymore to the
3087 application. Affected file lib/silcclient/client_notify.c.
3089 The ID Type is now also passed to the application so that
3090 it can check whether the returned entry is SilcClientEntry
3093 Added new function silc_client_get_server_by_id to return
3094 the server entry by ID. Affected files are the
3095 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3097 * Do not create the channel in the Irssi SILC Client when issuing
3098 the JOIN command but when received the sucessful JOIN command
3099 reply. Otherwise the channel might get created even though we
3100 could not join it. The Affected file is
3101 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3103 * Fixed a channel joining bug in router. The router must also
3104 check the channel modes, invite and ban lists etc. when serving
3105 the JOIN command sent by normal server. Affected file is
3106 silcd/command.c. The router now resolves the client's
3107 information from the server who sent the JOIN command if it
3108 does not know it, and processes the JOIN command only after
3111 * Changed the SilcCommandCb to take new argument; void *context2.
3112 Affected file lib/silccore/silccommand.h
3114 The second argument in the command callbacks in the server now
3115 includes the SilcServerCommandReplyContext if the command was
3116 called as pending command callback from the command reply.
3117 Otherwise it is NULL. When called as pending the status of the
3118 command reply will be checked and if it was erronous the
3119 error will be sent to the original sender of the command.
3120 This way the client always receives the error messages even
3121 though the server was actually the one who received the error
3122 when it resent the command to router, for example. Affected
3123 files silcd/command[_reply].[ch].
3125 * Fixed sending WHOWAS command's error message to client if
3126 the requested client could not be found. It was missing.
3129 * Changed the CMODE and CUMODE commands reply arguments in the
3130 protocol specification. The Channel ID is now sent in both
3131 of the commands to identify the channel. Implemented this
3132 new feature to the client and server. Affected files
3133 lib/silcclient/command_reply.c and silcd/command.c.
3135 * Made better checks for invite and ban lists in the JOIN
3136 command in server. Affected file silcd/command.c.
3138 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * The server now performs the incoming host IP/DNS lookup
3141 using the silc_socket_host_lookup and thus does not block
3142 the server anymore. Affected file silcd/server.c.
3144 * Completed the multi-thread support for SILC Scheduler in
3145 the lib/silcutil/silcschedule.c.
3147 * Fixed the configure.in.pre to detect the pthread correctly
3150 * Fixed a deadlock in silc_task_queue_wakeup in the file
3151 lib/silcutil/silctask.c.
3153 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * Added new function silc_schedule_wakeup that is used in
3156 multi-threaded environment to wakeup the main thread's
3157 schduler. It needs to be used when a thread adds a new task
3158 or removes a task from task queues. After waking up, the
3159 scheduler will detect the task queue changes. If threads
3160 support is not compiled in this function has no effect.
3161 Implemented the wakeup mechanism to both Unix and WIN32
3162 systems. Affected files are lib/silcutil/silcschedule.[ch],
3163 lib/silcutil/unix/silcunixschedule.c and the
3164 lib/silcutil/win32/silcwin32schedule.c.
3166 * Added new function silc_task_queue_wakeup to wakeup the
3167 scheduler by the specified task queue. Affected file
3168 lib/silcutil/silctask.[ch].
3170 * The silc_socket_host_lookup_start now wakes up the scheduler
3171 after adding the timeout task. Affected file is
3172 lib/silcutil/silcsockconn.c.
3174 * The silc_socket_host_lookup is synchronous now if the threads
3175 support is not compiled in. However, the callback is still
3176 called asyncronously through the scheduler, anyway. Affected
3177 file lib/silcutil/silcsockconn.c.
3179 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3181 * Added new function silc_socket_host_lookup to perform
3182 asynchronous IP and FQDN lookups for the socket connection.
3183 Affected files lib/silcutil/silcsockconn.[ch].
3185 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3188 that may or may not compile the mutex support in.
3190 Changed the silc_mutex_alloc interface. It allocates the
3191 mutex now to the sent pointer and returns TRUE or FALSE.
3193 Affected file lib/silcutil/silcmutex.h.
3195 * Wrote the SILC Task Queue interface to support multi-threads.
3196 Affected file lib/silcutil/silctask.[ch].
3198 * Wrote the SILC Scheduler to support multi-threads. Affected
3199 file lib/silcutil/silcschedule.c.
3201 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3204 in lib/silcutil/win32/.
3206 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Defined SILC Mutex API and SILC Thread API and implemented
3209 them for Unix. Affected files are
3210 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3211 lib/silcutil/unix/silcunixmutex.c and
3212 lib/silcutil/unix/silcunixthread.c.
3214 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3216 * Fixed the silc_server_remove_clients_by_server's channel
3217 key re-generation. The hash table handling was incorrect
3218 and would not work with many channels. Affected file is
3221 * Fixed some memory leaks around the server code.
3223 * Rewrote the silc_server_get_users_on_channel to support IPv6
3224 based Client ID's. Affected file silcd/server.c.
3226 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3227 specification. However, a separate document must be written
3228 to define the detailed signing procedure and the payload
3229 associated with the flag. Defined the flag to the
3230 lib/silccore/silcchannel.h as well.
3232 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Changed the dynamic tables to static size tables in the
3235 lib/silccrypt/silchmac.c.
3237 * Removed GCC dependencies from the code. A patch by cras.
3239 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Do not show the error "Error receiving packet bla bla"
3242 in server if it really was not an error (-2 means that reading
3243 is pending). Affected file silcd/server.c.
3245 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3247 * Fixed a possible crash in silc_server_remove_clients_by_server
3248 in silcd/server.c. Fixed there also some memory leaks.
3250 * Fixed the silc_idlist_replace_client_id. It could replace
3251 wrong key in the hash table. Affected file silcd/idlist.c.
3253 * Do not check whether there are global users on the channel
3254 if the channel->global_users is FALSE. Affected functions
3255 silc_server_remove_from_one_channel and
3256 silc_server_remove_from_channels in silcd/server.c. Also,
3257 do not check if the removed client is local as we can be
3258 sure that global client was not removed from the channel
3259 and checking for global users is not needed.
3261 * The silc_server_remove_clients_by_server now re-generates
3262 the channel keys correctly for those channels that had
3263 clients removed from them. Affected file silcd/server.c.
3265 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Found the reason of random crashes in the server. We weren't
3268 ignoring the SIGPIPE signal (which can be sent in write())
3269 and it crashed the server. Affected file silcd/silcd.c.
3271 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Assure that sock->user_data is not NULL in the function
3274 silc_server_packet_send in silcd/packet_send.c.
3276 * Disconnect the remote connection if it could not be added
3277 to any ID lists in the server. The affected file is
3280 * Check in silc_server_packet_send[_real/dest] that the
3281 socket is not disconnecting and ignore the data if it is.
3282 Affected file silcd/packet_send.c.
3284 * Define inline to __inline on native WIN32 compilation.
3285 Affected file includes/silcwin32.h.
3287 * Added some explicit type casts for inline code since MSVC
3288 require them. Affected files lib/silcutil/silcbuffer.h,
3289 lib/trq/silcdlist.h and lib/trq/silclist.h.
3291 * Print warning in log files from now on if the packet
3292 decryption fails. Affected file silcd/server.c.
3294 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Changed the `say' client operation's interface to accept
3297 new `type' argument to indicate the type of the message sent
3298 by the library. The application may filter the library's
3299 messages according the type. The affected file is the
3300 lib/silcclient/silcapi.h.
3302 * Added two new functions to lib/silcclient/silcapi.h:
3303 silc_client_del_client and silc_client_del_client_by_id.
3304 Affected file lib/silcclient/idlist.c.
3306 * Moved the clientincludes.h from includes/ to silc/ and
3307 serverincludes.h from includes/ to silcd/.
3309 * The modes for the CMODE and CUMODE are now passed as
3310 uint32 for application with COMMAND_REPLY. The affected
3311 file is lib/silcclient/command_reply.c.
3313 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3315 * /WHOIS without arguments shows client's own information.
3316 Affected file lib/silcclient/command.c.
3318 * Changed PING to not accept any arguments. The specs
3319 says that client can ping only the connected server so
3320 requiring an argument is not needed. Affected file is
3321 lib/silcclient/command.c.
3323 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Fixed a fatal bug in private message sending and reception
3326 encryption and decryption when using private message keys.
3327 The implementation was incorrect and did not follow the
3328 specification. It causd that some of the message were
3329 lost since it did not use the sending and receiving keys
3330 as the protocol suggests. This has been fixed and will cause
3331 incompatibilities with older clients when sending private
3332 message encrypted with private message keys. Affected files
3333 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3334 and various other in Irssi SILC Client.
3336 Added `responder' boolean argument to the functions
3337 silc_client_add_private_message_key[_ske] to indicate when
3338 the key is added as responder or initiator of the key
3341 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Removed the silc_ske_check_version function and created
3344 a SilcSKECheckVersion callback. Added also a function
3345 silc_ske_set_callbacks that is now used to set all SKE
3346 callbacks. The callback functions are not given to
3347 the SKE functions anymore, but this function is used to
3350 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3352 * Added `silc_version' argument to the silc_client_alloc
3353 to define the version of the application for the library.
3354 The library will use the version string to compare it
3355 against the remote host's (usually a server) version
3356 string. Affected file lib/silcclient/silcapi.h
3358 * Added the KE protocol context to Key Agreement context
3359 in client library so that we can abort the SKE if it
3360 is in process when we get timeout. Affected file is
3361 lib/silcclient/client_keyagr.c.
3363 * Do not resolve the client ID forever if it returns in the
3364 first time that such client does not exist. This was done
3365 for example with private message. Affected file is
3366 lib/silcclient/client_prvmsg.c.
3368 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Do not add regex.h for WIN32. The affected file
3371 includes/silcincludes.h.
3373 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3374 not work yet 100%. It generates the DLL's automatically
3375 when compiling with --with-win32 under cygwin.
3377 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3379 * lib/contrib/regex.c is not compiled on WIN32.
3381 * Added silc_net_get_socket_opt function to the
3382 lib/silcutil/silcnet.h.
3384 * Added includes/silcwin32.h for WIN32 specific includes
3387 * Do not use ptime structure or any of the posix process
3388 functions on WIN32 in lib/silccrypt/silrng.c.
3390 * Added silc_gettimeofday to provide generic function
3391 for struct timeval on all platforms. Added the function
3392 to lib/silcutil/silcutil.h.
3394 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3396 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3397 library as they clearly belong there. As a plus side we
3398 can make the actual socket connection routines platform
3401 Added also new generic function silc_socket_read and
3402 silc_socket_write (that used to be silc_packet_[read/write].
3403 The implementation of these are platform specific.
3405 * Added WIN32 specific routines of silc_socket_[read/write]
3406 to lib/silcutil/win32/silcwin32sockconn.c.
3408 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Added preliminary support for native WIN32 compilation under
3411 cygwin (using the -mno-cygwin option for GCC) to the
3412 ./configure.in.pre. The --with-win32 now prepares the
3413 compilation for native WIN32.
3415 * Rewrote the SILC Scheduler interface in the file
3416 lib/silcutil/silcschedule.h. The scheduler is now context
3417 based and does not have anymore any global static scheduler.
3418 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3419 and created lib/silcutil/win32 directory for WIN32 based
3422 * Added Unix specific network routines to the
3423 lib/silcutil/unix/silcunixnet.c and the old
3424 lib/silcutil/silcnet.c includes now only generic routines.
3426 Added WIN32 specific network routines to the
3427 lib/silcutil/win32/silcwin32net.c.
3429 * Added Unix specific utility functions from the
3430 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3432 * Added WIN32 SILC Scheduler to the file
3433 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3436 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Do not handle JOIN notify in the server if the target client
3439 is not registered (idata->registered == FALSE). The affected
3440 file is silcd/packet_receive.c.
3442 * Update the nickrec->founder in event_cumode in the Irssi SILC
3443 client. Affected file irssi/src/silc/core/silc-channels.c.
3445 * Fixed the CUMODE_CHANGE notify handling in the server when
3446 server and router are announcing their clients on channels.
3447 Now the mode changes are saved and notified correctly. The
3448 affected file is /silcd/packet_receive.c.
3450 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3451 They really did not replace the cache entry in the ID Cache.
3452 Now they do that. Affected file silcd/idlist.c.
3454 * Fixed the KICK notify handling in the Irssi SILC client to
3455 update the channel records so that the kicked client does not
3456 appear to be on the channel. The affected file is
3457 irssi/src/silc/core/silc-channels.c.
3459 * Always update the conn->current_channel when executing command
3460 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3462 * Fixed the KILL notify handling in Irssi SILC client to remove
3463 the killed client on all channels.
3465 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Fixed the silc_parse_command_line to remove extra spaces
3468 from the start and end of the arguments. Affected file is
3469 lib/silcutil/silcutil.c.
3471 * Cancel and free any active protocol in the function
3472 silc_server_close_connection. Affected file silcd/server.c.
3474 * Cancel and free any active protocol in the function
3475 silc_client_close_connction. Affected file is
3476 lib/silcclient/client.c.
3478 * Do not execute the KILL command for clients that are in
3479 history (ie. they are not in the network). Affected file is
3482 * Fixed KILL notify handling, client does not crash anymore.
3483 Affected file irssi/src/silc/core/silc-channels.c.
3485 * Reduced the default packet buffer size from 2048 to 1024 in
3486 lib/silccore/silcpacket.c.
3488 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3489 counter to the SKE context that is incresed when the SKE library
3490 performs async operation outside the library. If the outside
3491 process frees the SKE context and FREED status will be set
3492 and the library will detect after the sync operation that the
3493 libary is freed. The affected files are
3494 lib/silcske/silcske[_status].[ch].
3496 * Resolve the client entry information in the function
3497 silc_client_channel_message to assure that NULL pointer is not
3498 passed as client entry to the application. */
3500 * Fixed the task timeout calculation to assure that there is
3501 never negative timeouts. The affected file is
3502 lib/silcutil/silcschedule.c.
3504 * Fixed the channel user mode notification sending in server.
3505 It was sent point-to-point to the router (or to server by router)
3506 but it needs to be destined to a channel. The routines now
3507 supports sending the channel user mode notifys to the channels
3508 when announcing clients and channels. Affected files are
3509 silcd/server.c and silcd/packet_receive.c.
3511 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3512 It did not actually replace the old channel entry in the cache.
3513 Affected file lib/silcclient/client_notify.c.
3515 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Fixed a possible crash in silc_packet_send_prepare. It now
3518 assures always that there is enough space in the buffer and
3519 at the tail area of the buffer (for MAC).
3521 Fixed the inbound buffer reallocation in silc_packet_read.
3522 It was old code and did not handle the reallocation correctly.
3525 The affected file is lib/silccore/silcpacket.c.
3527 * Fixed buffer overflow in silc_parse_nickname in the file
3528 lib/silcutil/silcutil.c.
3530 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * make install generates new server keys only if there is not
3535 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3537 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3538 Added check that if the NOREPLY is set then we will not send
3539 the away message. This avoids infinite loop of away messages
3540 if both clients are away. The affected file is
3541 lib/silcclient/client_prvmsg.c.
3543 * Fixed client crash if /NICK was given without arguments.
3544 Affected file lib/silcclient/command.c.
3546 * Server does not send the invite list in INVITE command back
3547 to the client if the list was not altered. Added this notion
3548 to the protocol spec as well. Affected file silcd/command.c.
3550 Fixed possible crash in INVITE command by checking the
3551 value of silc_server_get_client_route command.
3553 * Fixed the INVITE notify type handling. The arguments are now
3554 taken in correct order and client does not crash. The affected
3555 file is irssi/src/silc/core/silc-channels.c.
3557 Removed the "Inviting xxx to channel" message from the
3558 client library away and let the application handle it.
3559 Affected file lib/silcclient/command.c. Added that message
3560 to Irssi SILC client's message formats.
3562 * Fixed CMODE command crash in client. It now checks the
3563 amount of arguments correctly and does not crash. The affected
3564 file is lib/silcclient/command.c.
3566 * Do not create new channel automatically in silc_channels_join
3567 but check whether the channel by that name already exists.
3568 Affected file irssi/silc/core/silc-channels.c.
3570 * Do not send the SERVER_SIGNOFF to router if the disconnected
3571 entity was the router. Affected file silcd/server.c.
3573 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3574 SILC client as it was missing from there.
3576 Added the handling of the KICK notify to the Irssi SILC client
3577 as it was missing. Added "you have been kicked" message to
3578 Irssi SILC client's message modules formats.
3580 Added the handing of the KILL notify to the Irssi SILC client
3581 as it was missing. Added the kill message module formats
3584 The affected file is irssi/src/silc/core/silc-channels.c.
3586 * The router did not save the channel mode the server announced.
3587 Affected file silcd/packet_receive.c.
3589 * Fixed a possible crash in INFO command in server. If the
3590 server did not provide the server info it crashed. Affected
3591 file silcd/command.c.
3593 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * Fixed the GETKEY command in the server to check also the
3596 global list. Otherwise the GETKEY would not work correctly
3597 in normal SILC server. Affected file silcd/command.c.
3599 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3601 * Fixed GETKEY crash, it crashed if the command did not succseed.
3603 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3606 is now real and not just an macro interface to GMP.
3608 Removed the entire GMP from the source tree and imported new
3609 NSS MPI library instead. Reason for removing GMP is that it is
3610 extremely large and compiles extremely slow. The NSS MPI
3611 is only a few files and compiles in less than 10 seconds.
3612 The speed is also about the same as GMP. The MPI is imported
3613 to lib/silcmath/mpi.
3615 If the system has GMP installed we will still use the GMP.
3616 If it is not then the NSS MPI will be compiled.
3618 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Merged a long nickname (127 characters long) crash bugfix from
3621 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3623 * Merged a freed memory reference bugfix from Irssi CVS tree.
3624 Affected file irssi/src/core/commands.c.
3626 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Added the server's public key sving and verification to the
3629 server when performing the SKE. This was missing and the
3630 remote server's (or router's) public key was accepted without
3631 checking whether we have it previously or trust it at all.
3632 Affected file silcd/protocol.c.
3634 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3636 * Check in the silc_server_timeout_remote if protocol is active
3637 and make sure that the protocol's final callback is called so
3638 that all memory if freed. Affected file silcd/server.c.
3640 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * silc_server_whois_send_reply crashed the server if the nickname
3643 was 127 characters long. Affected file silcd/command.c.
3645 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Added sanity check to the silc_server_new_client. If the hostname
3648 is provided inside username then check that the provided hostname
3649 really is the same as the resolved one. If the hostname was not
3650 resolved then check it from the public key. Affected file is
3651 silcd/packet_receive.c.
3653 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3654 if the server disconnected us and the connection is not valid
3655 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3657 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3658 the library to the lib/silcutil/silcutil.[ch].
3660 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Close log file after open. Affected file
3663 lib/silcutil/silclog.c.
3665 * Check whether sock == NULL in silc_client_send_packet and return
3666 if it is. Affected file lib/silcclient/silcclient.c.
3668 * Check rec->entry == NULL in the Irssi SILC Client before
3669 sending the channel message. Affecte file is
3670 irssi/src/silc/core/silc-servers.c.
3672 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Merged a splitted window bugfix from Irssi CVS tree. The
3675 affected file is irssi/src/fe-text/textbuffer-view.c.
3677 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3678 It did not print nickname.
3680 * Improved the distributions system a bit.
3682 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3685 irssi/src/fe-text/gui-window.c.
3687 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3688 to in-active server. The affected file is
3689 irssi/src/silc/core/client_ops.c.
3691 * Resolve the client in USERS command reply if the entry does
3692 not have username resolved. The affected file is
3693 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3694 command to WHOIS command to really resolve stuff. The USERS
3695 is not used any more in any critical section so WHOIS can
3696 be used even though it might be slower than IDENTIFY.
3698 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3701 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Changed the protocol API a bit more consistent in the
3704 lib/silccore/silcprotocol.[ch].
3706 * Changed the following headers to ROBODoc format:
3708 lib/silccore/silcpayload.h
3709 lib/silccore/silcprotocol.h
3710 lib/silccore/silcsockconn.h
3712 All core library headers are now formatted.
3714 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Fixed a bug in Irssi SILC client; do not show that you are
3717 server/router operator if you really are not. Affected file is
3718 irssi/src/silc/core/client_ops.c.
3720 * Renamed silc_command_free_payload to silc_command_payload_free.
3721 Affected file lib/silccore/silccommand.h
3723 * Added silcmath.h to include the prototoypes of various routines
3724 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3727 * Changed the following headers to ROBODoc format:
3729 lib/silccore/silcchannel.h
3730 lib/silccore/silccommand.h
3731 lib/silccore/silcid.h
3732 lib/silccore/silcidcache.h
3733 lib/silccore/silcmode.h
3734 lib/silccore/silcnotify.h
3735 lib/silccore/silcpacket.h
3736 lib/silcmath/silcmath.h
3738 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added checking to the server code not to start the server if
3741 ciphers and stuff are not configured properly. Affected files
3742 silcd/serverconfig.[h] and silcd/server.c.
3744 * Changed the layout of the header files of the public interfaces
3745 in the SILC libraries. The new layout supports ROBODoc
3746 documentation tool (and some others) so that it is easy to create
3747 a library reference manual. All the other headers and source
3748 code must still follow the CodingStyle document. Also source
3749 code must not include these ROBODoc stuffs, only the headers.
3750 Furthermore, all public interface headers must now be named
3751 by using `silc' prefix, example: silcapi.h, silccipher.h.
3752 Some files were renamed due to this. All the other headers
3753 must not be used as public interfaces. I will update the
3754 CodingStyle document later. Changed following headers, so far:
3756 lib/silcclient/silcapi.h
3757 lib/silccore/silcauth.h
3758 lib/silccore/silcprivate.h
3759 lib/silccrypt/silcdh.h
3761 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Removed silc_client_packet_send_flush from the client library
3766 as it is not needed. Affected file lib/silcclient/client.[ch].
3768 * Added printing of message of unresolved authentication method
3769 to the Irssi SILC client. Added it to the module formats.
3770 Removed the same message from the client library.
3772 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Added new distribution feature, DISTLABEL. Every distribution
3775 can define own preprocessor label that can be used in the
3776 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3777 file distributions, acconfig.h.pre and prepare.
3779 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Added Makefile.defines_int to include the actual definitions
3782 for Makefile.defines.in. Tested the new distribution system,
3783 created distributions and tested installation.
3785 * Added AWAY message printing to the Irssi SILC client. Added
3786 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3788 * Added SCONNECT command to call the SILC's CONNECT command.
3789 Cannot use CONNECT directly since Irssi uses that internally.
3790 Affected file irssi/src/silc/core/silc-servers.c.
3792 Added ACTION local command. It is same as ME command but takes
3793 the channel as mandatory argument.
3795 Rewrote some of the Irssi's help files to suite for SILC
3798 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Added Makefile.defines[.in] that should for now on be included
3801 in all Makefile.am file in the source tree. That file includes
3802 all common compilation definitions for SILC source tree.
3804 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Minor changes to the ./prepare script to change the package
3807 name according the distribution name to the configure.in.
3809 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Created new distribution system. Added file `distributions'
3812 that defines all the distributions that can be created out of
3813 the SILC source tree. The ./prepare script now reads that
3814 file to determine how to prepare the distributions. The
3815 first argument to the ./prepare is the name of the distribution
3816 and second is the version of the distribution. If given
3817 without arguments it creates the default (toolkit) distribution
3818 with the default version (defined in ./prepare).
3820 All Makefile.am files that are subject to the distributions
3821 are now named as Makefile.am.pre. These are ./Makefile.am
3822 and lib/Makefile.am. Others may be changed later.
3824 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Added invite list, ban list, some key management and connection
3827 error message printing to module formats in the Irssi SILC client.
3829 * Added new silc_client_set_away_message to set the away message
3830 that is back to the person who sent private message. The
3831 affected file lib/silcclient/silcapi.h and the
3832 lib/silcclient/client_prvmsg.c.
3834 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * Fixed the private message sending in the Irssi SILC client,
3837 added local command KEY to the Irssi SILC client.
3839 Added key management and key agreement message formats to the
3840 irssi/src/fe-common/silc/module-formats.[ch].
3842 Added USERS (alias WHO) printing, server/router operator
3843 indication and LIST command printing to the module formats.
3845 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed channel joining notify handling, cumode notify handling
3848 from Irssi SILC client.
3850 * Added SILC specific module-formats to the Irssi SILC client so
3851 that SILC specific message hilighting, colors etc is possible.
3852 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3854 Added channel mode, channel user mode, actions, notices,
3855 whois and whowas printing to the the module-formats.c.
3857 * Fixed a bug in channel deletion in the server. The channel
3858 is not left to the cache even if the channel founder auth mode
3859 is set when there are no users anymore on the channel. Affected
3860 file silcd/server.c.
3862 * The silc_net_localhost now resolves the entire hostname including
3863 the domain name. Affected file lib/silcutil/silcnet.c.
3865 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Changed the ask_passphrase client operation to be ascynchronous.
3868 It has now a completion callback and a context that the
3869 application must call after it has got the passphrase from
3870 the user. Affected files lib/silcclient/silcapi.h,
3871 lib/silcclient/protocol.c, lib/silcclient/command.c and
3874 Added SilcAskPassphrase callback that the application calls
3875 to deliver the passphrase to the library.
3877 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3878 The public key verification and especially a certificate
3879 verification is asynchronous procedure.
3881 Added new SILC_SKE_STATUS_PENDING status to indicate the
3882 request is pending and a callback will be called to finalize
3885 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3886 indicate that remote end did not send its public key (or
3887 certificate), even though we require it. Added check for this
3888 condition in the SKE. This was a security bug, now fixed.
3890 Defined new SilcSKEVerifyCbCompletion callback that is called
3891 when the verification process is completed.
3893 The affected files lib/silcske/silcske_status.h and
3894 lib/silcske/silcske.[ch].
3896 * Changed the verify_public_key client operation to be async
3897 as well. Defined SilcVerifyPublicKey callback that is used to
3898 indicate the success of the public key verification process.
3900 Changed the server and client to use the new async client
3903 * Changed the Irssi SILC client's internal scheduler to be called
3904 twice as many times as it used to be. As a result the client
3905 should be a bit faster now. Affected file is
3906 irssi/src/silc/core/silc-core.c.
3908 * Added support to Irssi SILC client of asynchronous public key
3909 verification and passphrase inquiry. Affected file is
3910 irssi/src/silc/core/silc-core.c.
3912 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3914 * Do not say "You have left channel %s" in client library.
3915 Moved it to the application. Affected files are
3916 lib/silcclient/command.c and silc/client_ops.c.
3918 * Fixed silc_client_get_clients. Command context was not
3919 duplicated and was freed memory in the callback. Affected
3920 file lib/silcclient/idlist.c.
3922 * Do not say "you are now talking..." on JOIN command in the
3923 client library. The appliation must handle it.
3925 * Do not say ".. changed topic to" in command reply in the
3926 client libary. The application must handle it.
3928 * Fixed TOPIC command sending in the client library.
3930 * Fixed a memory leak in silc_client_command_free in the file
3931 lib/silcclient/command.c.
3933 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Imported a modified version of Irssi client to the source tree.
3936 The Irssi will be used to create a new client called
3937 Irssi SILC. Imported to irssi/.
3939 Added silc_core_init_finish function to the Irssi. Affected
3940 file irssi/configure.in.
3942 A lot changes in the Makefile.ams around the irssi tree.
3944 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * Do not rehash if the new size is same as the old size of the
3947 hash table, in the silc_hash_table_rehash*. The affected file
3948 lib/silcutil/silchashtable.c.
3950 * Replaced hash_table_del_by_context calls from the server
3951 (when channel->user_list and client->channels) to the
3952 hash_table_del as it is sufficient and faster.
3954 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added silc_hash_table_list, silc_hash_table_get and the
3957 SilcHashTableList structure to provide an alternative way to
3958 traverse the hash table. The affected files are
3959 lib/silcutil/silchashtable.[ch].
3961 * Changed the server's idlist routines to use the hash table
3962 routines to optimize the code.
3964 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Replaced the client entry's `channel' list and channel entry's
3967 `user_list' list to hash tables for optimized lookup. Changed
3968 the code to use the hash table interface around the code.
3969 Affected file lib/silcd/idlist.[ch].
3971 * Added `auto_rehash' boolean argument to the function
3972 silc_hash_table_alloc to indicate whether the hash table should
3973 auto-rehash when it thinks is appropriate time. It will
3974 increase the hash table size if the there is twice as much
3975 entries in the table than the size of the table, and will
3976 decrease the size if there are twice as less entries than
3977 the size of the table.
3979 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3983 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * silc_idcache_purge_by_context deletes the entry now by context
3986 as it is supposed to do. Affected file lib/silccore/idcache.c.
3988 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3989 client is not anymore valid (WHOWAS givens the info) and not
3990 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3992 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Removed the `data' and `data_len' arguments from the ID Cache
3995 interfaces and added `name' argument. ID Cache does not handle
3996 anymore the binary data only a names associated with given ID.
3998 * When hashing a Client ID with silc_hash_id the entire ID is
3999 not hashed anymore, instead only the hash of the Client ID is
4000 hashed. This way we can access the Client ID from the cache
4001 with Client ID but with the hash of the ID (which is a hash of
4002 the nickname) as well without any difference in performance.
4004 Added also silc_idcache_find_by_id_one_ext to do one on one
4005 searching when we have the actual ID. Added also function
4006 silc_hash_client_id_compare. The affected files are
4007 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4009 * When hashing the name associated with a ID it is always done
4010 in lowercase. This way we can access the cache without worrying
4011 about case-sensitivity, even though, for example nicknames are
4014 * Fixed a bug in server with channel message sending. It put
4015 wrong ID type as destination ID. The affected file
4016 silcd/packet_send.c.
4018 * silc_idcache_del_by_context now deletes from all hash tables
4019 by context. Affected file lib/silccore/idcache.c.
4021 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Changed the client library to use the new ID Cache interface.
4024 Changes around the source tree.
4026 * Added silc_hash_table_rehash_ext to rehash with specific
4027 hash function. Affected file lib/silcutil/silchashtable.[ch].
4029 * Added silc_hash_string_compare to compare two strings in the
4030 hash table. Affected file lib/silcutil/silcutil.[ch].
4032 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Added new function silc_idcache_del_by_context into the
4035 lib/silccore/idcache.[ch].
4037 * Changed the server's ID list routines to use the new ID Cache
4038 interface. Changes around the source tree.
4040 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added silc_hash_table_del[_by_context]_ext functions in to the
4043 lib/silcutil/silchashtable.[ch].
4045 Removed silc_hash_table_find_all* routines and added new
4046 silc_hash_table_find_foreach to replace them.
4048 Added silc_hash_table_replace_ext function as extended
4049 replacing function. Separated the simple hash table interface
4050 from the extended hash table interface in the file
4051 lib/silcutil/silchashtable.h.
4053 * Fixed minor bugs and changed it to use some of the new
4054 hash table functions in lib/silccore/idcache.c
4056 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Added new function silc_hash_table_find_all to return all keys
4059 in the hash table by the specified key. As the hash table is
4060 collision resistant it also makes it possible to have several
4061 duplicate keys in the hash table. This function may be used to
4062 find all of the keys from the hash.
4064 Added user_context arguments to the SilcHashFunction,
4065 SilcHashCompare and SilcHashDestructor to deliver user specified
4068 Added new fuctions silc_hash_table_find[_all]_ext to do
4069 extended lookup with specified hash and compare functions and
4070 specified user contexts.
4072 Added new function silc_hash_table_add_ext to add the key
4073 with specified hash function and user context.
4075 Added new function silc_hash_table_foreach to traverse all
4076 entrys in the hash table. Added SilcHashForeach callback
4079 Added new function silc_hash_table_del_by_context to delete
4080 the entry only if the context associated with the key matches.
4082 Affected files are lib/silcutil/silchashtable.[ch].
4084 * Removed silc_hash_[server/client/channel]_id and added just
4085 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4086 silc_hash_id_compare to compare two ID's using as the hash table
4087 comparison function. Added also silc_hash_data to hash
4088 binary data and silc_hash_data_compare to compare it.
4090 * Removed silc_idlist_find_client_by_hash as it is not needed
4091 anymore. Affected file silcd/idlist.[ch].
4093 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4094 to use internally the SilcHashTable. The new ID Cache is a lot
4095 faster than the old one. Some of the ID Cache interface was also
4096 rewritten and obsolete and stupid functions were removed.
4098 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Added entry_count field to the SilcHashTable to keep the number
4101 of the entries in the table. Implemented the function
4102 silc_hash_table_rehash. Added new function
4103 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4105 Fixed a minor bug in silc_hash_table_free.
4107 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4108 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4109 into the lib/silcutil/silcutil.[ch].
4111 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Implemented a collision resistant hash table into the
4114 lib/silcutil/silchashtable[ch]. See the header and the source
4115 for the SilcHashTable API.
4117 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Merged dotconf version 1.0.2 into lib/dotconf.
4121 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Do not compile anything in lib/silcsim/* if the SIM support
4124 is not enabled. The tree should now compile without problems
4127 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Compiled the SILC under cygwin. Compiled and tested briefly
4130 without problems. More tests needed. The SIMs didn't compile
4133 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4135 * Fixed possible crash in silc_get_username in the
4136 lib/silcutil/silcutil.c.
4138 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Fixed a va_arg in silc/client_ops.c.
4142 * Oops, RC5 routines were named AES and caused some problems
4143 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4145 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Added new SilcIDIP structure into the lib/silccore/id.h and
4148 replaced the old `ip' fields from all SILC ID's to that type.
4149 This is a step towards IPv6 support.
4151 The silc_id_get_len takes now the ID as an extra argument.
4152 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4153 both IPv4 and IPv6 based ID's.
4155 The affected files are lib/silccore/id.[ch] and other files
4156 around the tree using these routines.
4158 * Removed the ID length arguments in server from various
4159 silc_server_send_notify_* routines -> they are not needed
4162 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Fixed memory leak in silc_encode_pem_file in the file
4165 lib/silcutil/silcutil.c.
4167 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Check minor version as well in the SKE. Affected files are
4170 silcd/protocol.c and lib/silcclient/protocol.c.
4172 * Added --identifier option to the server so that an identifier
4173 can be when creating the public key for the server. Affected
4174 file is silcd/silcd.c.
4176 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4177 lib/silccrypt/silcpkcs.c.
4179 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Register default ciphers and stuff when using -C option with
4182 the server. Affected file sildc/silcd.c.
4184 * Put back the servers public key filename format, it is better
4185 than the new one. For now, the client keys are saved with the
4186 new filename format. The affected file silc/client_ops.c.
4188 * Implemented the Cipher API for the rest of the ciphers that
4189 did not implement it or implemented it the wrong way.
4191 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Register default ciphers and stuff when using the -S option
4194 in the client. Affected file silc/silc.c. Same also when
4195 creating new key pair with -C option.
4197 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Fixed the silc_verify_public_key client operation function to
4200 save the public keys differently. The fingerprint is now
4201 used as filename and not the hostname. This way also the
4202 client keys are saved uniquely and not with hostnames. The
4203 affected file is silc/client_ops.c.
4205 * Trimmed the silc_hash_fingerprint function to remove extra
4206 whitespaces from the end of the fingerprint. The affected
4207 file is lib/silccrypt/silchash.c.
4211 * Added silc_cipher_register_default function to register all
4212 default ciphers. It can be used when configuration files
4213 does not exist and the application does not want any specific
4214 ciphers in any specific order.
4216 The SilcDList is now used as silc_cipher_list dynamically
4217 allocated cipher list. Removed the static list all together
4218 and now all ciphers must be allocated to the dynamic list.
4219 The silc_cipher_alloc routine was changed to check only the
4222 All silc_cipher_* routines that used to return int returns
4225 The affected files lib/silccrypt/silccrypt.[ch].
4227 * The same thing was done to silc_hash_* as for silc_cipher_*
4228 routines. Affected files lib/silccrypt/silchash.[ch].
4230 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4231 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4232 Added also silc_pkcs_[un]register[_default] functions.
4233 Removed the data_context from the PKCS API.
4235 * Added silc_hmac_register_default function to register default
4236 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4237 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4238 to unregister all hmacs at once.
4240 * Register the default ciphers, hash functions, PKCSs and HMACs
4241 if client's configuration file does not exist. The affected
4244 * The client did not load the hash functions from the SIM
4245 modules at all. Added support for this. Affected file is
4246 silc/clientconfig.c.
4248 * When decoding public key with silc_pkcs_public_key_decode, check
4249 the supported algorithm only if PKCS are registered. Affected
4250 file lib/silccrypt/silcpkcs.c. The same was done with the
4251 silc_pkcs_private_key_decode.
4253 * Fixed the SILC List routines to keep the list always in order.
4254 It used to change the list's order when traversing the list but
4255 not it preserves the order. Affected file lib/trq/silclist.h.
4257 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Added the client library to use the SilcSocketConnection's
4260 reference counter (by silc_socket_dup) to prevent the bug that
4261 the socket object may be freed underneath async operation.
4263 * The name resolv library checking fixes in the configure.in.pre.
4266 * Created new version of the protocol drafts for future
4267 development. The -03 drafts are the ones that will be changed
4268 in the trunk now and the -02 will remain as they are.
4270 * Send list of CUMODE notifys to the router when announcing
4271 the channel users to the router. Affected file silcd/server.c.
4272 If the router receiving channel founder CUMODE for a channel
4273 that already has channel founder it will send CUMODE notify
4274 to the sender to remove the channel founder rights from the
4275 announced client. Affected file silcd/packet_receive.c.
4277 * The CUMODE notify may now use Server ID as well as the entity
4278 who changes the mode. Updated protocool specs.
4280 * Updated INSTALL and README files.
4282 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * New web pages in the http://silc.pspt.fi. The pages was
4289 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Implemented the [DenyConnectin] config section in the server.
4292 Added silc_server_config_denied_conn to check whether incoming
4293 connection is denied. Affected file silcd/serverconfig.[ch].
4295 * Do not check the ports when checking the incoming configuration
4296 data if the port is 0, meaning any. Affected file is
4297 silcd/serverconfig.c.
4299 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Fixed buffer overflow in silc_string_compare in the file
4302 lib/silcutil/silcutil.c.
4304 * Fixed double free in silc_server_command_leave in the file
4307 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Fixed the version checking in the server. Affected file is
4312 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Fixed the configuration data fetching when accepting new
4315 connections in the server. Affected file silcd/server.c.
4317 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Added `sender_entry' argument to the function
4320 silc_server_packet_relay_to_channel so that we can check
4321 whether some destination actually belongs to the same route
4322 the sender belongs (ie, we must not resend the packet to the
4323 sender). Affected file silcd/packet_send.[ch].
4325 * Added `servername' field to the SilcClientEntry in the server
4326 to hold the name of the server where client is from. Affected
4327 file is silcd/idlist.h.
4329 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Moved the channel message encrypting in the router betwen
4332 router connections from silc_server_channel_message to the
4333 silc_server_packet_relay_to_channel since we want to check
4334 whether we have anybody channel before encrypting anything.
4335 Affected files silcd/packet_[receive/send].c.
4337 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Fixed the [AdminConnection] server config section to support
4340 multiple entries. Affected file silcd/serverconfig.c.
4342 * Added support into the server to check the validity of the
4343 incoming connection before executing any KE or authentication
4346 * The connection configuration is now saved to the KE and
4347 connection auth protocol contexts and not fetched anymore in
4348 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4350 * The local hosts listenning address and port is also resolved
4351 now when starting the server. We want to have the socket object
4352 to include the real address and port for the listener. Added
4353 new function silc_net_check_local_by_sock into the files
4354 lib/silcutil/silcnet.[ch].
4356 * Fixed a broadcast bug in server -> do not broadcast if we
4359 * Fixed a routing bug. Do not route broadcast packets ever.
4360 Broadcast packets must be processed always and not routed since
4361 they may be destined to some other host than yourself and thus
4362 would get routed without no good reason. Affected file is
4365 * Added function silc_server_config_is_primary_route to check
4366 whether primary router connection has been configured (a router
4367 configuration that we are initiating). If there is not, we
4368 will assume that there is only two routers in the SILC network
4369 and we will use the incoming router connection as our primary
4370 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4372 * Changed the order of the broadcasting. Broadcast _after_ the
4373 packet has been processed not before. Affected file is
4376 * Fixed a [ClientConnection] parsing bug. The port was never
4377 parsed correctly thus resulting to port 0. Affected file
4378 silcd/serverconfig.c.
4380 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4381 argument and did not set the broadcast packet flag. Affected
4382 file silcd/packet_send.c. Fixed same bug in the function
4383 silc_server_send_notify as well.
4385 * If we receive NEW_ID packet for our own ID in the server, ignore
4388 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Removed the nickname from the Private Message Payload.
4393 Updated the code and the protocol specs.
4395 * Updated protocol specs for submitting to the IETF.
4397 * Tweaked the Random Number Generator a bit. Affected file
4398 lib/silccrypt/silcrng.c. Exported a new function
4399 silc_rng_[global]_add_noise which can be used to add more
4402 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Do not parse packets with different timeout when protocol
4405 is active -> may cause problem with rekey. Affected file
4408 * When server receives signoff notify it must not create
4409 new channel key if the client is on any channels since the
4410 sender of the signoff notify will create it.
4412 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Added printing of error messages during SKE protocol from the
4415 failure packet sent by server during SKE. Affected file
4418 * Removed the client's failure_callback handling with timeout
4419 and handle it immediately when received.
4421 * The SKE library returned wrong type in SUCCESS and FAILURE
4422 packets. They must be 32 bit MSB not 16 bit MSB.
4424 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Ok, rewrote the logic of the re-key and now it seems to work.
4427 I tested it on high traffic with frequent re-keys without
4428 problems. Added hmac_receive (and renamed hmac to hmac_send)
4429 in SilcClientConnection in lib/silcclient/client.h and
4430 in SilcIDListData in silcd/idlist.h. Also, removed the
4431 SilcPacketParserContext's cipher and hmac fields as they are
4432 not needed anymore and actually caused some problems when
4433 the ciphers and hmac's changed underneath the packet parser.
4435 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * If re-key protocol is active then process the incoming packets
4438 synchronously since we must assure that icoming packets encrypted
4439 with the old key is processed before the new keys is set to
4440 use. This is true other packets than for REKEY packets.
4441 Affected file silcd/server.c. The same was done to client library
4442 as well, affected file lib/silcclient/client.c.
4444 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Fixed bug in client and server to accept the force send if
4447 the packet is send from silc_[server/client]_packet_process
4448 function. Otherwise the packets are never delivered, oops.
4450 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Disable force sending of packets when REKEY protocol is active.
4453 We must assure that no packet is sent directly when rekey is
4454 performed. All packets must be sent through packet queue.
4455 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4456 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4457 function is silc_[server/client]_packet_send_real to check
4460 * Replaced the SIM paths from example config files to
4461 /usr/local/modules. Also, make install creates now
4462 /usr/local/silc/logs directory to hold all the SILC server
4465 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Made the configure.in.pre work on Solaris. Patch by salo.
4469 * Made all ciphers compatible with non-x86 machines. Defined
4470 CBC mode macros into lib/silccrypt/ciphers_def.h.
4472 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Fixed the make install.
4476 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * When MAC computation fails the silc_packet_decrypt returned 0
4479 even though it was supposed to return -1. Fixed this. The
4480 affected file is lib/silccore/silcpacket.c.
4482 * Do not replace the config files in /etc/silc (in make install)
4483 if they already exist. Affected file ./Makefile.am.
4485 * Do not send re-key packets immediately but through packet queue.
4486 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4488 * Changed silc_net_check_host_by_sock to return FALSE if the
4489 IP/DNS could not be resolved. Though, it returns the IP address
4490 now even if it could not resolve it (but returns also FALSE).
4491 Affected file lib/silcutil/silcnet.[ch].
4493 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Added silc_pkcs_decode_identifier to decode the public key's
4496 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4497 Added also silc_pkcs_free_identifier. Added also new context
4498 SilcPublicKeyIdentifier.
4500 * Added -S option to the silc client. It is used to dump the
4501 contents of the specified public key file.
4503 * Changed the PKCS api to return the public key length when
4504 setting the public key.
4506 * Fixed a fatal bug in the public and private key file loading.
4507 Affected file lib/silccrypt/silcpkcs.c.
4509 * Execute the packet parsing for client with zero (0) timeout
4510 if the protocol is active. Affected file silcd/server.c.
4512 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Made the key generation options to the silcd program. Added
4515 -C option, equivalent to client's option.
4517 * Added new [ServerKeys] config section to the server. It
4518 configures the server's public and private key.
4520 * Defined generic Public Key Payload into the protocol
4521 specification to send specific type of public keys and
4524 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4525 public key or certificate.
4527 * Implemented the GETKEY command to the server and to the
4528 client library and on user interface.
4530 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Made preliminary `make install' work.
4534 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Added SilcServerRekey context into silcd/idlist.h.
4538 * Added the PFS support as defined in the specification to the
4539 SKE protocol. Affected files lib/silcske/*.c.
4541 * Added `ske_group' field to the SilcServerRekey context to hold
4542 the number of the SKE group that is used with PFS in re-key.
4543 Affected file silcd/idlist.h.
4545 * Added PFS re-key support to the server. Affected file is
4548 * Added silc_protocol_cancel to cancel execution of the next
4549 state of the protocol. Affected file is
4550 lib/silccore/silcprotocol.[ch].
4552 * Added the re-key support with and without PFS to the client
4553 library. Re-key is performed once in an hour, by default.
4555 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4556 Added silc_client_rekey_callback and silc_client_rekey_final.
4557 Affected files are lib/silcclient/protocol.[ch] and
4558 lib/silcclient/client.[ch].
4560 * Removed the `hmac_key' and `hmac_key_len' fields from the
4561 SilcClientConnection structure; not needed. Affected file is
4562 lib/silcclient/client.h.
4566 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Do not ask whether user wants to use the negotiated private key
4569 for private messages, just use it. Affected file is
4570 silc/local_command.c.
4572 * Added `send_enc_key' and `enc_key_len' fields to the
4573 SilcIDListData structure since they are needed in the re-key
4574 phase. Affected file is silcd/idlist.[ch].
4576 * Implemented the simple re-key protocol into the server.
4577 Affected files silcd/server.c and silcd/protocol.[ch]. The
4578 re-key will be performed once in an hour, by default.
4580 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4581 Added silc_server_rekey, silc_server_rekey_callback and
4582 silc_server_rekey_final.
4584 * Removed Tunneled flag from the protocol. Updated the code
4585 and the specifications.
4587 * Adde `pfs' field to the SilcIDListData to indicate whether
4588 the PFS is to be performed in the re-key. Affected file is
4591 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4594 int64 of at least the xintXX size. If void * is less that 4
4595 bytes uint32 * will be used. Defined bool as boolean.
4597 * Changed _ALL_ unsigned long and unsigned int to uint32,
4598 unsgined short to uint16 in the source tree.
4600 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4601 not handle clients that has entry->data.registered == FALSE.
4602 They are not in the network anymore. Affected file is
4605 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Implemented the sending of the SERVER_SIGNOFF notify in the
4608 server. Affected file is silcd/server.c.
4610 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4611 Added also silc_notify_payload_encode_args into the
4612 lib/silccore/silcnotify.[ch].
4614 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4615 Affected file silcd/packet_receive.c.
4617 * Implemented the SERVER_SIGNOFF notify handling in the client
4618 library. Affected file lib/silcclient/client_notify.c. Also,
4619 implemnted the printing of the SERVER_SIGNOFF info to the
4620 application. Affected file silc/client_ops.c.
4622 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4623 if the deleting was successful. Affected file silcd/idlist.[ch].
4625 * Added support for public key authentication in the connection
4626 authentication protocol in the client library. Affected file
4627 lib/silcclient/protocol.c.
4629 * Changed the server's silc_idlist_get_clients_by_* interface
4630 to support already allocated array so that new entries may be
4631 added to pre-allocated array. Affected file silcd/idlist.[ch].
4632 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4633 and command replies.
4635 * All command reply functions in the server now calls the
4636 pending command callback even if error occured. This way the
4637 error will be delivered to the client as well. Affected files
4638 silcd/command.c and silcd/command_reply.c.
4640 * Fixed INFO command to return local server's info if no server
4641 was provided. Affected file lib/silcclient/command.c.
4643 * Removed RESTART command for good. Updated the code and the
4646 * Rewrote parts of the task system. It is a bit simpler now.
4647 Removed unsued task priorities. The affected files are
4648 lib/silcutil/silctask.[ch].
4650 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Moved the USERS printing from the library to the application.
4653 Affected files lib/silcclient/command.c and silc/client_ops.c.
4655 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added channel key re-key support. The re-key is perfomed
4660 only by the router and is done once in an hour. Added `rekey'
4661 field to the SilcChannelEntry in the server. Affected files
4662 silcd/server.c and silcd/idlist.h.
4664 * Added silc_task_unregister_by_context into the file
4665 lib/silcutil/silctask.[ch].
4667 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added SILC_UMODE_GONE mode to indicate when the client is not
4670 present in the SILC network. Added also support to the local
4671 command AWAY that will set this mode. Added support of showing
4672 "xxx is gone" in WHOIS command. The USERS command shows the
4673 gone status as well.
4675 * Fixed setting server and router operator privileges in the
4676 server's UMODE command. Affected file silcd/command.c.
4678 * Merged the SKE KE1 and KE2 payloads into one payload. The
4679 new KE payload is equivalent to the old KE2 payload.
4681 Cleaned up the SKE Start Payload parsing. It now uses the
4682 simple buffer unformatting to do the parsing. A lot faster
4685 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4686 to the SKE that is used to indicate whether both of the SKE
4687 parties should perform authentication. By default only the
4688 responder performs authentication. By setting this flag also
4689 the initiator must do authentication. By default it is unset
4690 since in normal SKE case, client to server connection, only
4691 the responder should do authentication. When doing SKE between
4692 two clients both should perform authentication. Updated the
4693 code and the protocol specs.
4695 * A little fix to IDENTIFY command in the server. Search the
4696 client first by hash not nickname. Affected file is
4699 * Fixed the silc_client_close_connection to support closing
4700 the client to client connections wihtout deleting too much
4701 data. Affected file lib/silcclient/client.c.
4703 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4704 are received if protocol used to be active but is not anymore
4705 the application would crash due to NULL pointer dereference.
4706 Affected files silcd/server.c and lib/silcclient/client.c.
4708 * Added `hash' field to the SilcClientConnection to include
4709 the hash function negotiated in the SKE protocol.
4711 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4712 to set the channel founder authentication data. A client can
4713 claim the founder rights later by providing the authentication
4714 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4715 This way the channel founder can regain the channel founder
4716 privileges even it is left the channel. This works only on
4717 local server and the client must be connected to the same
4718 server to be able to regain the founder rights. Updated the
4719 protocol specs accordingly.
4721 Added support to the CMODE command in the client to set the
4722 founder auth data. Read the README to see how to set it.
4724 Added support to the CUMODE command to claim the founder
4725 rights. Read the README to see how to do it.
4727 Added support for the founder authentication to the Channel
4728 Entry in the server. Affected file silcd/idlist.h.
4730 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4731 server's CMODE command. Affected file silcd/command.c.
4733 * Added the following new functions into lib/silccore/silcauth.[ch]:
4734 silc_auth_get_method and silc_auth_get_data.
4736 * The server now saves the remote hosts public key to the
4737 SilcIDListData pointer. Affected file silcd/protocol.c.
4739 * The normal server now does not remove the channel entry from
4740 the cache if the founder authentication data is set. It used
4741 to remove it if the founder was the last one on the channel on
4742 the server and left the channel. The auth data is saved and
4743 if the channel is re-joined later the old entry is used with
4744 the old auth data. Affected files silcd/command_reply.c and
4747 * Removed the `pkcs' field from the SilcIDListData structure
4748 in the server; it is not used. Affected file silcd/idlist.h.
4750 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Fixed packet processing on slow links. Partial packets were
4753 never re-processed because the incoming data buffer was cleared
4754 by the application. Application must not directly clear the
4755 sock->inbuf, the packet processing routines handle it. Fixed
4756 this in client library and in server.
4758 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Fixed the WHOIS and IDENTIFY send reply function to really
4761 check whether to send list or just one entry. Affected file
4764 * Cleaned up the LEAVE command's channel key distribution. The
4765 affected file silcd/command.c.
4767 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4768 can enforce the channel mode as well. In that case the ID
4769 includes the ID of the server. The code now enforces the
4770 mode change if the router have different mode than the server.
4772 * The notify client operation with CMODE_CHANGE notify can now
4773 return NULL client_entry pointer if the CMODE was not changed
4774 by client. Application must check for this.
4776 * Added <Server ID> argument to INFO command to support server
4777 info fetching by Server ID.
4779 * Added silc_server_announce_get_channel_users to get assembled
4780 packets of channel users of the specified channel. Affected
4781 file silcd/server.[ch].
4783 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4784 was freed underneath the ID Cache.
4786 * Re-announce clients when the server received CHANNEL_CHANGE
4787 notify from the router. Affected file silcd/packet_send.c.
4789 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4791 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4792 crashed since it did not handle the fact that there is no cipher
4793 called "3" and didn't check the error condition. Now fixed.
4795 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4796 flag. It can be used to send message requests.
4798 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Implemented the RESTART command in the client.
4802 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4803 notice type messages. Added notice printing to the user
4806 * The channel keys are not re-generated if the channel's mode
4807 is PRIVKEY, ie private key on the channel exists. Affected
4808 files silcd/server.c and silcd/command.c.
4810 * Fixed a little bug in channel message delivery when channel
4811 private keys are set in the server. Affected file is
4812 silcd/packet_send.c.
4814 * Changed the setting on channel->on_channel = TRUE from the
4815 silc_client_save_channel_key to the JOIN command reply. The
4816 key payload is not received if the private channel key is set.
4817 Affected file lib/silcclient/command_reply.c and the
4818 lib/silcclient/client_channel.c.
4820 * When the CMODE_CHANGE notify is sent and the channel private
4821 key mode is removed the channel key must be re-generated in
4822 other cells as well. Added this support for the router in the
4823 silcd/packet_receive.c.
4825 * Added new local command NOTICE to send notice message on
4826 channel. Affected file silc/local_command.[ch].
4828 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Added new local command ME to the client. It is used to send
4831 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4832 some action. Affected file silc/local_command.[ch].
4834 * Changed channel_message and private_message client operations
4835 to deliver the message flags to the application. Added also
4836 the `flags' arguments to the silc_client_send_channel_message
4837 and silc_client_send_private_message functions. Affected file
4840 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Redefined the Private Message Payload to support private message
4843 keys and to support the new private message flags. Updated
4844 the protocol specs. Flags makes it possible to have for example
4845 CTCP style messages.
4847 * Added new type SilcPrivateMessagePayload and defined an API
4848 for it in the lib/silcclient/silcprivate.[ch].
4850 * Tested private message private keys successfully. Tested the
4851 private message key set, unset and list commands with the new
4854 * Redefined the Channel Message Payload to include the channel
4855 message flags (equal with private message flags) to support
4856 for example CTCP style messages.
4858 * Defined some of the message (for channel and private message)
4859 flags. Updated the protocol specs and added the flags to the
4860 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4862 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added SilcKeyAgreementStatus type to the key agreement routines
4865 to indicate the current status and error if one occured.
4866 The status types are defined in the lib/silcclient/silcapi.h.
4868 * Added new local command KEY that is used to set and unset private
4869 keys for channels, set and unset private keys for private messages
4870 with remote clients and to send key agreement requests and
4871 negotiate the key agreement protocol with remote client. The
4872 key agreement is supported only to negotiate private message keys,
4873 it currently cannot be used to negotiate private keys for channels,
4874 as it is not convenient for that purpose.
4876 * Fixed a minor pending callback setting bug in the function
4877 silc_client_get_client_by_id_resolve, now the function works.
4878 Affected file lib/silcclient/idlist.c.
4880 * Added function silc_net_get_local_port to get local bound
4881 port by socket. Added to lib/silcutil/silcnet.[ch].
4883 * Added `sockets' and `sockets_count' fields to the SilcClient
4884 object. They hold the sockets of the listenning sockets in
4885 the client. Listenning sockets may be for example the key
4886 agreement server. Affected file lib/silcclient/client.[ch].
4887 Added functions the silc_client_add_socket and the
4888 silc_client_del_socket. They are exported to the application
4891 * Added ~./silc/clientkeys to support other client's public keys.
4893 * Renamed verify_server_key client operation to verify_public_key
4894 and added one argument to indicate the type of the connection
4895 (server, client etc.).
4897 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added silc_server_connection_auth_request to handle the
4900 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4901 silcd/packet_receive.[ch].
4903 * Added silc_server_send_connection_auth_request into the
4904 silcd/packet_send.c to send the connection auth request packet.
4906 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4909 * Fixed the public key authentication in responder side in the
4910 server. The `auth_data' pointer includes the SilcPublicKey
4911 not the path to the public key. Affected file silcd/protocol.c.
4913 * Implemented the public key authentication in the initiator side
4914 in the server. Affected file silcd/protocol.c.
4916 * Removed the [RedirectClient] config section from the server
4917 configuration. Is not needed and I don't want to implement it.
4919 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4921 * Cleaned up the CMODE command in the server. It now works
4922 correctly and supports all the modes defined in the protocol.
4923 Affected file is silcd/command.c.
4925 * Added `hmac_name' field to the SilcChannelEntry in the server
4926 to hold the default HMAC of the channel. It can be set when
4927 creating the channel (with JOIN command). Affected files
4930 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4931 type to indicate the change of the current cipher and hmac
4932 on the channel. Client can safely ignore the <cipher> argument
4933 (if it chooses to do so) since the CHANNEL_KEY packet will
4934 force the channel key change anyway. The <hmac> argument is
4935 important since the client is responsible of setting the new
4936 HMAC and the hmac key into use.
4938 * Fixed the CMODE command in the client library as well.
4940 * Tested CMODE command in router environment successfully.
4942 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Show the version of the remote client (or server) when connecting
4945 to the server. It is logged to the log file. Affected file
4946 is silcd/protocol.c.
4948 * Fixed the KILLED notify handling in the client library. The
4949 client must be removed from all channels when receiving the
4952 Also, do not remove the client entry when giving the KILL
4953 command but when the KILLED notify is received.
4955 * Removed silc_idlist_find_client_by_nickname from the server.
4956 Not needed anymore. Affected files silcd/idlist.[ch].
4958 * Implemented the CHANNEL_CHANGE notify type handling to the
4959 server. Affected file silcd/server.c.
4963 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Added silc_server_send_notify_invite to send the INVITE
4966 notify between routers.
4968 * Implemented the INVITE command correctly to the server.
4970 * Implemented the INVITE notify type handling in the server.
4972 * Implemented the INVITE command to the client library and on the
4975 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Added function silc_server_get_client_resolve to find the
4978 client entry by ID from all ID lists and then resolve it
4979 (using WHOIS) if it cannot be found. Affected file is
4982 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Implemented the BAN command to the client library.
4986 * The JOIN command in the server now checks the invite list
4989 * Changed the silc_command_reply_payload_encode_va and the
4990 silc_command_payload_encode_va to support that if argument is
4991 NULL it ignores and checks the next argument. Affected file
4992 lib/silccore/silccommand.c.
4994 * Added silc_server_send_notify_ban to send the BAN notify
4995 type between routers.
4997 * Chaned the silc_notify_payload_encode to support that if
4998 argument is NULL it ignores and checks the next argument.
4999 Affected file lib/silccore/silcnotify.c.
5001 * Tested ban lists in router environment successfully.
5003 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Implemented BAN command to the server, in silcd/command.[ch].
5007 * Removed the BAN and INVITE_LIST modes from the CMODE command
5010 * Added function silc_string_match to regex match two strings.
5011 Affected files lib/silcutil/silcutil.[ch].
5013 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Redefined parts of the SilcChannelEntry in the server to support
5016 the new ban and invite lists.
5018 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Redefined the INVITE command. The same command can be used to
5021 invite individuals to the channel but also to manage the invite
5022 list of the channel (to add to and remove from the invite list).
5023 Updated the protocol specs.
5025 * Added new command SILC_COMMAND_BAN that can be used to manage
5026 the ban list of the channel. Updated the protocol specs.
5028 * Removed the channel modes: the SILC_CMODE_BAN and the
5029 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5030 in the CMODE command. The equivalent features are now available
5031 using INVITE and BAN commands. Updated the protocol specs.
5033 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5034 in the network about change in the current ban list. The notify
5035 type is not used by the client.
5037 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5038 support the invite lists.
5040 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added new function silc_string_regexify that converts string
5043 including wildcard characters into regex string that can
5044 be used by the GNU regex library. Added into the file
5045 lib/silcutil/silcutil.[ch].
5047 Added silc_string_regex_combine to combine to regex strings
5048 into one so that they can be used as one regex string by
5049 the GNU regex library. Added into the file
5050 lib/silcutil/silcutil.[ch].
5052 Added silc_string_regex_match to match two strings. It returns
5053 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5055 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Imported GNU regex to the soruce tree into lib/contrib.
5058 Fixed some compiler warning from the regex.c.
5060 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Fixed MOTD command in the server to work in router environment.
5064 * Fixed the MOTD command in the client library to support
5065 the server argument in the command.
5067 * Added `nickname_len' argument to the silc_idlist_add_client
5068 in the server, as the `nickname' argument may be binary data
5071 * Added silc_idlist_get_channels to return all channels from
5074 * Implemented LIST command to the server. Affected file is
5077 * Implemented the LIST command to the client library and on the
5080 * Added [<user count>] argument to the LIST command reply.
5081 With private channels the user count is not shown.
5083 * Updated TODO and README.
5085 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * The client entry's data.registered must be TRUE even with
5088 global client entry on global client list. The data.registered
5089 is used to check whether the client is anymore in the network,
5090 for example with WHOWAS command so it must be valid.
5092 * Fixed the WHOWAS command in the server. It now actually works
5093 in router environment. Added function into silcd/command_reply.c
5094 silc_server_command_reply_whowas_save.
5096 * Added silc_idlist_purge function to the silcd/idlist.c
5097 to periodically purge the ID Cache.
5099 * Fixed INFO command in the server. It works now in router
5100 environment. Added <server name> argument to the INFO command
5101 reply. Updated the protocol specs.
5103 * Fixed minor bug in silc_idcache_purge to not purge if the
5104 expire value is zero.
5106 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5107 they were buggy because of the WHOWAS information.
5109 * Fixed local command MSG to handle the async resolving of
5110 the remote client properly. It used to fail the first MSG.
5111 Affected file silc/local_command.c.
5113 * Added `data_len' field to SilcIDCache context.
5115 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5117 * Update TODO. Todo in commands in the server.
5119 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5122 used by routers as broadcast packet to inform other routers
5123 about the changed user mode.
5125 Implemented the notify handling in the server. Affected file is
5126 silcd/packet_receive.c. Added the function
5127 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5129 * Added new generic Channel Payload and deprecated the New Channel
5130 Payload. The New Channel Payload is now the generic Channel
5133 * Added new argument `mode' to the silc_server_send_new_channel
5134 as it is required in the Channel Payload now.
5136 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5137 and created a new and real SilChannelPayload to represent the
5138 new generic Channel Payload. Implemented the encode/decode
5139 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5141 * Added silc_server_get_client_channel_list to return the list
5142 of channels the client has joined for WHOIS command reply.
5143 Affected file silcd/server.[ch].
5145 * Implemented the channel list sending in the WHOIS command reply
5146 in server and in the client.
5148 Implemented the channel list displaying on the user interface
5149 as well. Affected file silc/client_ops.c.
5151 * Added silc_channel_payload_parse_list to parse list of Channel
5152 Payloads. It returns SilcDList list of SilcChannelPayloads.
5153 Client for example can use this function to parse the list of
5154 channels it receives in the WHOIS command reply. The caller
5155 must free the list by calling silc_channel_payload_list_free.
5156 Affected files lib/silccore/silcchannel.[ch].
5158 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Added one new argument <user mode> to the WHOIS command reply
5161 to return the mode of the user in SILC. Updated the protocol
5164 Implemented it to the server and client.
5166 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Fixed the mode printing on the user interface on joining.
5169 Affected file silc/client_ops.c.
5171 * Implemented the UMODE command and user modes in general to the
5172 client library and to the user interface.
5174 * Implemented the UMODE command to the server.
5176 * The server now sends UNKNOWN_COMMAND error status if client sends
5177 unknown command. Affected file silcd/command.c.
5179 * All server commands now handle the command identifier the right
5180 way when sending the command reply to the client. The client can
5181 use to identify the command replies with the identifier.
5183 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Added silc_server_get_client_route to resolve the route to
5186 the client indicated by the client ID. Affected file is
5189 * Added silc_server_relay_packet as general function to relay
5190 packet to arbitrary destination. This deprecates functions
5191 like _send_private_message_key, _relay_notify etc. Affected
5192 file is silcd/packet_send.[ch].
5194 Removed silc_server_send_key_agreement,
5195 silc_server_send_private_message_key and
5196 silc_server_packet_relay_notify functions from the file
5197 silcd/packet_send.[ch].
5201 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5202 server. Affected file silcd/packet_receive.[ch].
5204 * Implemented the KILL command to the client. Implemented the
5205 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5206 Affected files lib/silcclient/command[_reply].c and
5207 lib/silcclient/client_notify.c. Implemented the KILL notify
5208 printing in the user inteface.
5210 * Fixed a lot silc_parse_nick memory leaks from the client
5211 library in the file lib/silcclient/command.c.
5213 * Changed the silc_server_send_notify_on_channels's `sender'
5214 argument from SilcSocketConnection to SilcClientEntry to
5215 check the sender as entry and not as connection object and not
5216 to send to the client provided as argument. The affected file
5217 is silcd/packet_send.[ch].
5219 * The notify packets that are destined directly to the client used
5220 to not to be processed by the server. Now changed that and the
5221 server processes all notify packets. After relaying the packet
5222 to the client the notify packet is processed in the server.
5224 * The silc_server_free_client_data now checks whether there is
5225 pending outgoing traffic for the client and purges the data to
5226 the network before removing the client entry.
5228 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5231 an client is killed from the SILC Network. Updated the protocol
5234 Added new function silc_server_send_notify_killed to the
5235 silcd/packet_send.[ch].
5237 * Added function silc_server_packet_relay_notify to relay notify
5238 packets that are destined directly to a client. In this case
5239 the server does not process the notify packets but merely relays
5240 it to the client. Affected file silcd/packet_send.[ch].
5242 Added also silc_server_packet_process_relay_notify to check
5243 whereto relay the notify. Affected file is
5244 silcd/packet_receive.[ch].
5246 * Implemented the KILL command to the server.
5250 * Added the backup schema desgined last fall to the protocol
5251 specs for everyone to see. The specification is in the
5252 *-spec-xx.txt draft and the packet type definitions for the
5253 backup routers is in *-pp-xx.txt draft. Thusly, added also
5254 new packet type SILC_PACKET_CELL_ROUTERS.
5256 * A big security problem in the implementation discovered. The
5257 signoff of an client did not cause new channel key generation
5258 which it of course should've done. The channel keys must be
5259 always re-generated when client leaves (or signoffs) the channel.
5260 The silc_server_remove_from_channels funtion now handles
5261 the channel key re-generation.
5263 * Added `sender' argument to the silc_server_send_notify_on_channels
5264 to not to send the client provided as argument. Affected file
5265 silcd/packet_send.[ch].
5267 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Implemented OPER and SILCOPER commands into the server and
5272 * Added silc_auth_verify and silc_auth_verify_data to verify
5273 the authentication directly from the authentication payload.
5274 It supports verifying both passphrase and public key based
5275 authentication. Affected file lib/silccore/silcauth.[ch].
5277 * Added `hash' field to the SilcIDListData structure. It is the
5278 hash negotiated in the SKE protocol. Affected file is
5281 * Slight redesigning of the SilcAuthPayload handling routines.
5282 Do not send SilcPKCS but SilcPublicKey as argument.
5284 * Implemented the public key authentication support to the
5285 serverconfig. The public key is loaded from the provided path
5286 and saved as authentication data to void * pointer. Thus,
5287 changed the unsigned char *auth_data to void *auth_data;
5289 * Fixed SHUTDOWN command to send the reply before the server
5290 is shutdown. :) Affected file silcd/command.c.
5292 * Fixed fatal bug in CONNECT command. The hostname was invalid
5293 memory and server crashed. Affected file silcd/command.c.
5295 * Fixed fatal bug in CLOSE command. The server_entry became
5296 invalid but was referenced later in the command. Affected file
5299 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5301 * Fixed fatal bug in failure packet handling. Server ignored
5302 the failure and thus crashed when it came.
5306 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5309 that the command may be executed only once in (about) 2 seconds.
5310 The old SILC_CF_LAG flag is same but allows command bursts up
5311 to five before limiting.
5313 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5314 server code. Various commands now includes the CF_LAG_STRICT
5315 flag to disallow any kind of miss-use of the command.
5317 * Fixed the silc_buffer_unformat to not to allocate any data
5318 if the length of the data is zero. It used to allocate the
5319 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5321 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Changed the format of AdminConnection configuration section
5324 in the server. Added username of the admin to the format.
5325 Affected files silcd/serverconfig.[ch].
5327 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5328 to return admin configuration data by host, username and/or
5331 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Implemented WHOWAS command to the server. Added the functions:
5335 silc_server_command_whowas_parse,
5336 silc_server_command_whowas_send_reply,
5337 silc_server_command_whowas_from_client and
5338 silc_server_command_whowas_from_server
5340 * Added <Client ID> argument to the WHOWAS command reply. Updated
5341 the protocol specs accordingly.
5343 * Implemented WHOWAS command and command_reply to the client
5346 Implemented the WHOWAS printing on the user interface.
5348 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Added new argument to the WHOWAS command reply, the real name.
5351 It is an optional argument. Updated the protocol specs.
5353 * Added SilcIDCacheDestructor callback that is registered when
5354 the SilcIDCache is allocated. The callback is called when
5355 an cache entry in the ID Cache expires, or is purged from the
5356 cache. Added into lib/silccore/idcache.[ch].
5358 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5359 to destruct the client entries when the cache entry expires.
5360 Other ID Cache's in server and in the client library ignores
5363 * If the ID Cache entry's `expire' field is zero then the entry
5364 never expires. Added boolean `expire' argument to the
5365 silc_idcache_add function in the lib/silccore/idcache.[ch].
5366 If it is TRUE the default expiry value is used.
5368 * Added silc_server_free_client_data_timeout that is registered
5369 when client disconnects. By default for 5 minutes we preserve
5370 the client entry for history - for WHOWAS command.
5372 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added support to the server to enforce that commands are not
5375 executed more than once in 2 seconds. If server receives
5376 commands from client more frequently, timeout is registered
5377 to process the commands. Affected file silcd/command.c.
5378 Added new function silc_server_command_process_timeout.
5380 * Changed NICK_NOTIFY handling in client library to check that
5381 if the client's nickname was changed, so there is no need to
5382 resolve anything from the server.
5384 * Removed error printing from the WHOIS and IDENTIFY commands.
5385 If error occurs then it is ignored silently in the client library.
5386 The application, however, may map the received error to
5387 human readable error string. The application currently maps
5388 the NO_SUCH_NICKNAME error to string.
5390 * Made the command status message public to the application. Moved
5391 them from lib/silcclient/command_reply.c to
5392 lib/silcclient/command_reply.h. The application can map the
5393 received command status to the string with the
5394 silc_client_command_status_message function.
5396 * Added check to the server to check that client's ID is same
5397 as the Source ID in the packet the client sent. They must
5400 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Added dist-bzip hook to the Makefile.am to make bzip2
5403 compressed distributions.
5405 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Server now enforces the maximum length for the nickname and
5408 the channel as protocol specification dictates. 128 bytes for
5409 nickname and 256 bytes for channel name.
5411 * Moved the WHOIS printing to the application. The client libary
5412 does not print out the WHOIS information anymore, the application
5413 must do it. Renamed silc_client_command_reply_whois_print to
5414 the silc_client_command_reply_whois_save.
5416 The client's idle time is also sent to the application now, and
5417 the idle is shown on screen.
5419 * Added silc_client_command_reply_identify_save to save the
5420 received IDENTIFY entries.
5422 * Do not check for channel private keys in message sending and
5423 reception if the channel does not have the PRIVKEY mode set.
5424 Affected file lib/silclient/client_channel.c.
5426 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5429 just surfaced after chaning the JOIN procedure.
5431 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Added silc_client_get_clients_by_list to get client entries
5434 from Client ID list, that is returned for example by JOIN
5435 and USERS command replies. The application should use this
5436 function for example when JOIN command reply is received to
5437 resolve the clients already on the channel (library does not
5438 do that anymore as USERS command reply is not used in the JOIN
5439 procedure anymore). Affected files lib/silcclient/silcapi.h and
5440 lib/silcclient/idlist.c.
5442 * JOIN command reply and USERS command reply returns now SilcBuffer
5443 pointers instead of unsigned char pointers when returning
5444 the client list and mode list.
5446 * Added <Client ID> argument to the JOIN command reply, mainly
5447 for the server to identify for which client the command was
5448 originally sent. Updated protocol specs accordingly.
5450 * Added SilcDlist private_key pointer to the SilcChannelEntry
5451 in the client to support the channel private keys. Affected
5452 file is lib/silcclient/idlist.h.
5454 * Added SilcChannelPrivateKey argument to the function
5455 silc_client_send_channel_message so that application can choose
5456 to use specific private ke if it wants to. If it is not provided,
5457 the normal channel key is used, unless private keys are set.
5458 In this case the first (key that was added first) is used
5459 as the encryption key.
5461 * Implemented the support for channel private key handling.
5462 Implemented the following functions:
5464 silc_client_add_channel_private_key,
5465 silc_client_del_channel_private_keys,
5466 silc_client_del_channel_private_key,
5467 silc_client_list_channel_private_keys and
5468 silc_client_free_channel_private_keys
5470 Affected file lib/silcclient/client_channel.c.
5472 * Added the support for the private keys in the channel message
5473 sending and encryption and in the message reception and
5474 decryption. Affected funtions are
5475 silc_client_send_channel_message and silc_client_channel_message.
5477 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Added SKE's key verify callback to the client library's
5480 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5482 * Removed the statement that server (or router) must send USERS
5483 command reply when joining to the channel so that the client
5484 knows who are on the channel. Instead, the client list and
5485 client's mode list is now sent in the JOIN command reply to the
5486 client who joined channel. This is better solution.
5488 * Added function silc_server_get_users_on_channel and function
5489 silc_server_save_users_on_channel to the silcd/server.[ch].
5491 * Removed function silc_server_command_send_users from the
5494 * Do not show topic on the client library anymore. The topic is
5495 sent in the command reply notify to the application and the
5496 application must show the topic now.
5498 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added client searching by nickname hash into the IDENTIFY and
5501 WHOIS commands in the server as they were clearly missing from
5502 them. Affected file is silcd/command.c.
5504 * Fixed a bug in private message receiving in the client library.
5505 The remote ID was freed and it wasn't supposed, now it is
5508 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Minor fix to the channel payload; allocate the data area, as it
5511 needs to be of specific length.
5513 * If the key agreement port is zero then the operating
5514 system will define the bound port. Affected files are
5515 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5517 * Added new function silc_channel_payload_decrypt into the file
5518 lib/silccore/silcchannel.[ch].
5520 * Moved the channel message etc, check from silc_packet_decrypt
5521 to applications. The library calls now a generic
5522 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5523 when the packet is either normal or special. This was done to
5524 allow more wide range of checking that was not allowed when
5525 the code was in library. Now applications can do virtually any
5526 checks to the packet and return to the library the decision how
5527 the packet should be processed. Affected files are
5528 lib/silccore/silcpacket.[ch].
5530 Added silc_server_packet_decrypt_check to the server and
5531 silc_client_packet_decrypt_check to the client library.
5533 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5534 to send with specified source and destination information.
5536 * Channel message delivery between routers was broken after the
5537 channel key distribution was fixed earlier. The channel key
5538 was used be to distributed to other routers as well which is not
5539 allowed by the protocol. Now this is fixed and channel keys
5540 really are cell specific and the channel message delivery between
5541 routers comply with the protocol specification.
5543 * Fixed various commands in server to check also the global list
5544 for the channel entry and not just the local list. The affected
5545 file silcd/command.c.
5547 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added assert()s to buffer formatting and unformatting routines
5550 to assert (if --enable-debug) when error occurs. Affected
5551 file: lib/silcutil/silcbuffmt.c.
5553 * Changed to auto-reconnect to check whether the remote host is
5554 router and register the re-connect timeout if it is. It used
5555 to check that whether we are normal server, but router must do
5556 auto-reconnect with another router as well. Affected file
5559 * Removed the [<key len>] option from CMODE command as the cipher
5560 name decides the key length, nowadays. See the defined ciphers
5561 from the protocol specification.
5563 * Added [<hmac>] option to the CMODE command to define the HMAC
5564 for the channel. Added SILC_CMODE_HMAC channel mode.
5566 * Added [<hmac>] option for the JOIN command so that user can
5567 select which HMAC is used to compute the MACs of the channel
5570 * Added Hmac field to the Channel Message Payload. The integrity
5571 of plaintext channel messages are now protected by computing
5572 MAC of the message and attaching the MAC to the payload. The
5573 MAC is encrypted. Now, it is clear that this causes some
5574 overhead to the size of the packet but rationale for this is that
5575 now the receiver can verify whether the channel message decrypted
5576 correctly and also when private keys are set for the channel the
5577 receiver can decrypt the packet with several keys and check from
5578 the MAC which key decrypted the message correctly.
5580 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5581 lib/silccrypt/silccipher.[ch].
5583 * Added silc_hash_len to return the digest length into the
5584 lib/silcrypt/silchash.[ch].
5586 * Rewrote parts of Silc Channel Payload interface in the
5587 lib/silccore/silcchannel.[ch]. The encode function now also
5588 encrypts the packet and parse function decrypts it.
5590 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Fixed a minor formatting bug in the SKE's key material processing.
5593 It actually might have processed the keys wrong way resulting
5596 * Redefined the mandatory HMAC algorithms and added new algorithms.
5597 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5598 and hmac-md5 truncated to 96 bits. The mandatory is now
5599 hmac-sha1-96. Rest are optional (including the one that used
5600 to be mandatory). Rationale for this is that the truncated HMAC
5601 length is sufficient from security point of view and can actually
5602 make the attack against the HMAC harder. Also, the truncated
5603 HMAC causes less overhead to the packets. See the RFC2104 for
5606 * Added new [hmac] configuration section. The SKE used to use
5607 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5608 is of course wrong. The official names that must be proposed in
5609 the SKE are the ones defined in the protocol specification
5610 (hmac-sha1-96 for example). The user can configure any hmac
5611 using any hash function configured in the [hash] section. At
5612 least, the mandatory must be configured.
5614 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5616 * Added HMAC list to the SKE proposal list. It has now both
5617 hash algorithm list and HMAC list. This makes the protocol
5618 incompatible with previous versions. The SKE now seems to work
5619 the way it is supposed to work, for the first time actually.
5621 * Defined plain Hash algorithms to the protocol specification.
5624 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Implemented support for key agreement packets into the server.
5627 Added functions silc_server_key_agreement and
5628 silc_server_send_key_agreement. Other than these functions,
5629 server has nothing to do with this packet.
5631 * Added support for private message key packets into the server.
5632 Added functions silc_server_private_message_key and
5633 silc_server_send_private_message_key.
5637 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5638 called in the protocol's final callback instead in the END
5639 protocol state. This makes a little more sense and in the same
5640 time in client we can use the same protocol routines for normal
5641 key exchange and to key agreement packet handling as well.
5643 * Added to both client's and server's KE protocol context the
5644 SilcSKEKeyMaterial pointer to save the key material. We will
5645 bring the key material to the protocol's final callback by doing
5646 this. The final callback must free the key material.
5648 * Added SKE's packet_send callback into client's KE protocol
5649 context so that the caller can choose what packet sending function
5650 is used. This way we can use different packet sending when
5651 doing normal SKE when doing key agreement packet handling (in
5652 the key agreement packet handling we do not want to encrypt
5655 * Implemented the responder side of the key agreement routines
5656 in the client. The client can now bind to specified port and
5657 accept incoming key negotiation. The key material is passed
5658 to the application after the protocol is over.
5660 * Implemented the processing of incoming Key Agreement packet
5661 in the client. Added function silc_client_key_agreement to
5664 * Implemented the intiator side of the key agreement routines
5665 in the client. The client can now initiate key agreement with
5666 another remote client. The key material is passed to the
5667 application after the protocol is over.
5669 * Created client_keyagr.c to include all the key agreement
5672 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5673 SILC_TASK_CALLBACK except that it is not static.
5675 * Created client_notify.c and moved the Notify packet handling
5676 from the client.[ch] into that file.
5678 * Created client_prvmsg.c and moved all private message and
5679 private message key routines from the client.[ch] into that file.
5681 * Create client_channel.c and moved all channel message and
5682 channel private key routines from the client.[ch] into that file.
5684 * Changed silc_client_get_client_by_id_resolve to resolve with
5685 WHOIS command instead of IDENTIFY command, in the file
5686 lib/silclient/idlist.c.
5688 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Implemented the SKE's responder side to the Client library.
5692 * When FAILURE is received to the protocol do not trust it
5693 blindly. Register a timeout to wait whether the remote closes
5694 the connection as it should do it, only after that process the
5695 actual failure. This was changed to both client and server.
5697 * Added client_internal.h to include some of the structures
5698 there instead of client.h in lib/silcclient/.
5700 * Added function silc_task_unregister_by_callback to unregister
5701 timeouts by the callback function.
5703 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Some "Incomplete WHOIS info" errors has been appearing on the
5706 log files. Took away the entry->userinfo check from WHOIS
5707 reply sending. The entry->userinfo is now " " if client did not
5708 provide one. I thought this was fixed earlier but something
5709 is wrong still. Let's see if the error still appears.
5711 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5713 * Fixed a minor bug in the login when the channel key is
5714 re-generated in the server. It used to generate the key in
5715 wrong order and thus caused problems in the channel traffic.
5717 * Fixed a minor bug in channel key distsribution after
5718 KICK command. The key was not sent to the router even though
5721 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Added silc_ske_process_key_material_data as generic routine
5724 to process any key material as the SILC protocol dictates. The
5725 function is used by the actual SKE library but can be used by
5726 applications as well. This relates to the private message keys
5727 and the channel private keys since they must be processed the
5728 same way the normal SILC session keys. The protocol dictates
5729 this. Affected files: lib/silcske/silcske.[ch].
5731 Added also silc_ske_free_key_material to free the
5732 SilcSKEKeyMaterial structure.
5734 * Defined silc_cipher_set_key function to set the key for
5735 cipher without using the object's method function. The affected
5736 files: lib/silccrypt/silccipher.[ch].
5738 * Implemented silc silc_client_add_private_message_key,
5739 silc_client_add_private_message_key_ske,
5740 silc_client_del_private_message_key,
5741 silc_client_list_private_message_keys and
5742 silc_client_free_private_message_keys functions in the
5745 Added functions silc_client_send_private_message_key to send
5746 the Private Message Key payload and silc_client_private_message_key
5747 to handle incoming Private Message Key payload.
5749 * Added Cipher field to the Private Message Key payload to set
5750 the cipher to be used. If ignored, the default cipher defined
5751 in the SILC protocol (aes-256-cbc) is used.
5753 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Removed lib/silcclient/ops.h file.
5757 Redefined parts of the SILC Client Library API. Created new
5758 file silcapi.h that deprecates the ops.h file and defines the
5759 published Client Library API. Defined also private message key
5760 API and channel private key API into the file.
5762 This is the file that the application must include from the
5763 SILC Client Library. Other files need not be included by
5764 the application anymore.
5766 * Added new key_agreement client operation callback and also
5767 defined the Key Agreement library API for the application.
5769 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5771 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5772 is used by clients to request key negotiation between another
5773 client in the SILC network. If the negotiation is started it
5774 is performed using the SKE protocol. The result of the
5775 negotiation, the secret key material, can be used for example
5776 as private message key.
5778 Implemented the Key Agreement payload into the files
5779 lib/silccore/silauth.[ch].
5781 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Redefined ciphers for the SILC protocol. Added some new ciphers
5784 and defined the key lengths for the algorithms. Changed the
5785 code accordingly. The default key length is now 256 bits.
5787 * Fixed SKE key distribution function silc_ske_process_key_material
5788 when the key length is more than 128 bits. The default key
5789 length in SILC is now 256 bits.
5791 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5792 to indicate unsupported algorithm.
5794 * Renamed rijndael.c to aes.c and all functions as well.
5796 * Fixed a long standing channel key setting bug in client library.
5797 Weird that it has never surfaced before.
5799 * Fixed bug in channel deletion. If the entire channel is removed
5800 then it must also delete the references of the channel entry
5801 from the client's channel list as the client's channel entry and
5802 the channel's client entry share same memory.
5804 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Implemented CONNECT and SHUTDOWN commands in the client.
5808 * Implemented CLOSE command to the client.
5810 * Added the function silc_idlist_find_server_by_name into the
5811 files silcd/idlist.[ch].
5813 Added the function silc_idlist_find_server_by_conn into the
5814 files silcd/idlist.[ch].
5816 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * DIE command was renamed to SHUTDOWN. Updated the both code
5821 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5822 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5824 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5827 * Added function silc_server_create_connection function to create
5828 connection to remote router. My server implementation actually
5829 does not allow router to connect to normal server (it expects
5830 that normal server always initiates the connection to the router)
5831 so the CONNECT command is only good for connecting to another
5834 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5837 or some other client was kicked from the channel.
5839 Implemented the handling of the notify type to both client
5842 Implemented silc_server_send_notify_kicked to send the KICKED
5843 notify. It is used to send it to the server's primary router.
5845 * Implemented the KICK command into server and client.
5847 * Added `query' argument to the silc_idlist_get_client function
5848 to indicate whether to query the client from server or not if
5851 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5852 to indicate that the client is not channel founder.
5856 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Removed the rng context from SilcPacketContext structure and
5859 changed that the packet routine uses the Global RNG API.
5861 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added support for quit message that client can "leave" on the
5864 channel when it quits the SILC. It is ditributed inside the
5865 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5867 Added silc_server_free_client_data that will take the
5868 signoff message as argument.
5870 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5872 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5874 * Updated parts of the protocol specification to keep it up
5877 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5880 payloads in one packet.
5882 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5883 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5884 use now the new List flag.
5886 * Also deprecated the following packet types: REPLACE_ID,
5887 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5889 * Added list support for Notify packet in server.
5891 * Added silc_server_send_notify_channel_change to send the
5892 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5893 the silc_server_send_replace_id.
5895 * Added silc_server_send_notify_nick_change to send the
5896 NICK_CHANGE notify type. Deprecates the function
5897 silc_server_send_replace_id.
5899 * Added silc_server_send_notify_join to send the JOIN notify type.
5900 Deprecates the function silc_server_send_new_channel_user.
5902 * Added silc_server_send_notify_leave to send LEAVE notify type.
5903 Deprecates the function silc_server_send_remove_channel_user.
5905 * Added silc_server_send_notify_cmode and
5906 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5907 types. Deprecates the silc_server_send_set_mode function.
5909 * Added SERVER_SIGNOFF notify type to indicate that server has
5910 quit. This means that all clients on the channel from that
5911 server will drop. This can be also used when netsplit happens.
5913 Deprecated REMOVE_ID packet type since it is not needed anymore
5916 Added silc_server_send_notify_server_signoff to send the
5917 SERVER_SIGNOFF notify type. Deprecates the function
5918 silc_server_send_remove_id.
5920 Added also silc_server_send_notify_signoff to send the
5921 SIGNOFF notify type.
5923 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5924 SILC protocol from this day on. Changed the protocol
5925 specification as well.
5927 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5928 notify type. It is used between routers to notify about
5929 topic changes on a channel.
5931 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5934 * Partly updated the protocol specification to comply with the
5935 changes now made. It is still though a bit outdated.
5937 * The JOIN notify type now takes one extra argument <Channel ID>.
5938 The packet used to be destined to the channel but now the
5939 JOIN type may be sent as list thus it is impossible to
5940 destine it to any specific channel. By adding this argument
5941 it is again possible.
5943 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Added CREDITS file. The CHANGES and CREDITS file will appear
5946 in the distribution as well.
5948 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5951 types in the server's silcd/packet_receive.c.
5953 * Implemented CMODE and CUMODE to work in router environment.
5955 * Fixed minor encoding and decoding buglet from the
5956 lib/silccore/silcmode.c.
5958 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5961 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5963 * Changed all SilcConfigServer* and silc_config_server* to
5964 SilcServerConfig* and silc_server_config*, respectively.
5967 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Associated the ID (client or server ID) to the Authentication
5970 Payload to avoid any possibility of forging. Updated the
5971 protocol specification and the code accordingly.
5973 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * The RSA key length is now save to the RsaKey context in the
5976 key generation process in lib/silccrypt/rsa.c. The key length
5977 is now used to figure out the maximum size of the block allowed
5978 to be encrypted/signed.
5980 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5981 is equivalent to the silc_mp_mp2bin but does not allocate any
5984 * Changed silc_mp_mp2bin API to take length argument. If it is
5985 non-zero then the buffer is allocated that large. If zero, then
5986 the size is approximated using silc_mp_sizeinbase, which however
5989 * Created Global RNG API which is global RNG that application can
5990 initialize. After initializing, any routine anywhere in the
5991 code (including library) can use RNG without allocating a new
5992 RNG object. This was done to allow this sort of use of the
5993 RNG in code that has no chance to allocate RNG object. All
5994 applications currently allocate this and many routines in the
5995 library use this. Affected file lib/silccrypt/silcrng.[ch].
5997 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5998 it to use the Global RNG API.
6000 * Defined Authentication Payload into protocol specification that
6001 is used during SILC session to authenticate entities. It is
6002 used for example by client to authenticate itself to the server
6003 to obtain server operator privileges.
6005 Implemented this payload into the lib/silccore/silcauth.[ch].
6006 Implemented also routines for public key based authentication
6007 as the new protocol specification dictates.
6009 Moved definitions of different authentication methods from
6010 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6012 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6013 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6014 silc_pkcs_verify_with_hash functions into the file
6015 lib/silccrypt/silcpkcs.[ch].
6017 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * The client entry's userinfo pointer must be always valid.
6020 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6021 will fail since it requires the userinfo. Now, the userinfo
6022 is allocated as "" if actual userinfo does not exist. Actually,
6023 it must exist and it is totally Ok to drop client connections
6024 that does not announce the userinfo. However, we will make
6025 this workaround for now.
6027 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6028 to return the remote port by socket.
6030 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6033 SILC_SERVER_PENDING_EXEC and added an new macro
6034 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6035 data or when error occurs while processing the pending command.
6037 Added new argument `destructor' into silc_server_command_pending
6038 and to the SilcServerCommandPending object. This destructor is
6039 now called after calling the pending callback or if error occurs
6040 immediately. If error occurs the actual pending callback won't
6041 be called at all - only the destructor. The destructor may be
6042 NULL if destructor is not needed.
6044 All this applies for client library code as well. Similar
6045 changes were made there as well for the pending commands.
6047 In the client, the application must now allocate the
6048 SilcClientCommandContext with the silc_client_command_alloc
6051 * Added reference counter to the SilcServerCommandContext. Added
6052 function silc_server_command_alloc and silc_server_command_dup
6055 Same type of functions added to the client library for the same
6058 * Removed the cmd_ident from IDListData away since it is now
6059 global for all connections. It is the command identifier used
6060 in command sending and with pending commands. The affected file
6063 * Added reference counter to the SilcSocketConnection objecet to
6064 indicate the usage count of the object. The object won't be
6065 freed untill the reference counter hits zero. Currently only
6066 server uses this, and client ignores it. The client must be
6067 set to use this too later. The affected files are
6068 lib/silccore/silcsockconn.[ch]. Added also the function
6069 silc_socket_dup to increase the reference counter.
6071 This was mainly added because it is possible that the socket
6072 is removed underneath of pending command or other async
6073 operation. Now it won't be free'd and proper DISCONNECTING
6074 flags, etc. can be set to avoid sending data to connection that
6075 is not valid anymore.
6077 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6078 the connection. After that it sets SILC_SET_DISCONNECTED.
6079 It is, however, possible that the socket data is not still freed.
6080 The silc_server_packet_process now checks that data is not
6081 read or written to connection that is DISCONNECTED. The socket
6082 get's freed when the reference counter hits zero.
6084 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Changed the client operation API: channel_message operation's
6087 `sender' is now the client entry of the sender, not the nickname
6088 and the `channel' is the channel entry, not the channel name.
6090 In the private_message operation the `sender' is now also the
6091 client entry of the sender not the nickname.
6093 Affected file is lib/silcclient/ops.h and all applications
6094 using the client operations.
6096 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Moved the calling of ops->connect() from connect_to_server_final
6099 into receive_new_id functin since that is the point when the
6100 client is actually allowed to send traffic to network. The
6101 affected file is lib/silcclient/client.c.
6103 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6106 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6107 (if needs broadcasting) instead of broadcasting the packets one
6108 by one which would make a burst in the network traffic.
6110 * Added `broadcast' argument to the functions in silcd/server.[ch]
6111 silc_server_create_new_channel[_with_id] to indicate whether
6112 to send New Channel packet to primary router.
6114 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Added new function into the silcd/server.[ch] files:
6117 silc_server_create_new_channel_with_id to create new channel with
6118 already existing Channel ID.
6120 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6121 lib/silccore/silcpacket.h. This packet is used t send list of
6122 Set Mode payloads inside one packet. Server uses this to set
6123 the modes for the channels and clients on those channels, that it
6124 announced to the router when it connected to it. The protocol
6125 specification has been updated accordingly.
6127 * The silc_server_new_channel did not handle the packet coming
6128 from normal server as it normally does not send that. However,
6129 when it announces its channels it does send it. Implemented
6130 the support for that.
6132 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6133 into the file lib/silccore/id.h.
6135 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6137 * Fixed memory leaks in the functions silc_idlist_del_client,
6138 silc_idlist_del_channel and silc_idlist_del_server in the file
6139 silcd/idlist.c. All of those leaked like a sieve.
6141 * Fixed some small memory leaks in the client's function
6142 silc_client_notify_by_server.
6144 * Added functions into silcd/server.c: silc_server_announce_clients,
6145 silc_server_announce_channels and silc_server_announce_server.
6146 These functions are used by normal and router server to announce
6147 to its primary router about clients, channels and servers (when
6148 router) that we own. This is done after we've connected to the
6151 These functions effectively implements the following packet types:
6152 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6153 and SILC_PACKET_NEW_ID_LIST.
6155 * Added new functions into the silcd/packet_receive.[ch]:
6156 silc_server_new_id_list, silc_server_new_channel_list and
6157 silc_server_new_channel_user_list to handle the incoming
6158 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6160 * Added support of changing Channel ID in the function
6161 silc_server_replace_id. If the server that announces a channel
6162 to the router already exists in the router (with same name but
6163 with different Channel ID), router is responsible to send
6164 Replace ID packet to the server and force the server to change
6165 the Channel ID to the one router has.
6167 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6168 client that the Channel ID has been changed by the router. The
6169 normal server sends this to the client. Client must start using
6170 the new Channel ID as the channel's ID.
6172 Implemented handling of this new type into lib/silcclient/client.c
6173 into the function silc_client_notify_by_server.
6175 * Added new function silc_idlist_replace_channel_id into the files
6176 silcd/idlist.[ch] to replace the Channel ID.
6178 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Call silc_server_command_identify_check always when processing
6181 the IDENTIFY command in silcd/command.c
6183 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6185 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6186 send keepalive packets. The packet can be sent by clients,
6187 servers and routers.
6189 Added function silc_socket_set_heartbeat into the file
6190 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6191 If not set, the heartbeat is not performed. The actual
6192 heartbeat is implemented in the low level socket connection
6193 library. However, application is responsible of actually
6196 Added silc_server_send_heartbeat to send the actual heartbeat
6197 packet into silcd/packet_send.[ch]. Server now performs
6198 keepalive with all connections.
6200 * Added silc_task_get_first function into lib/silcutil/silctask.c
6201 to return the timeout task with shortest timeout. There was a bug
6202 in task unregistration that caused problems. TODO has been
6203 updated to include that task system must be rewritten.
6205 * The client library will now resolve the client information when
6206 receiving JOIN notify from server for client that we know but
6207 have incomplete information.
6209 * Rewrote parts of silc_server_remove_from_channels and
6210 silc_server_remove_from_one_channel as they did not remove the
6211 channel in some circumstances even though they should've.
6213 * Encryption problem encountered in server:
6215 The LEAVE command used to send the Channel Key packet to the
6216 router immediately after generating it. However, the code
6217 had earlier sent Remove Channel user packet but not immediately,
6218 ie. it was put to queue. The order of packets in the router
6219 was that Channel Key packet was first and Remove Channel User
6220 packet was second, even though they were encrypted in the
6221 reverse order. For this reason, MAC check failed. Now, this
6222 is fixed by not sending the Channel Key packet immediately but
6223 putting it to queue. However, this is more fundamental problem:
6224 packets that are in queue should actually not be encrypted
6225 because packets that are sent immediately gets encrypted
6226 actually with wrong IV (and thus MAC check fails). So, packets
6227 that are in queue should be encrypted when they are sent to
6228 the wire and not when they put to the queue.
6230 However, the problem is that the current system has not been
6231 designed to work that way. Instead, the packet is encrypted
6232 as soon as possible and left to the queue. The queue is then
6233 just purged into wire. There won't be any fixes for this
6234 any time soon. So, the current semantic for packet sending
6237 o If you send packet to remote host and do not force the send
6238 (the packet will be in queue) then all subsequent packets to the
6239 same remote host must also be put to the queue. Only after the
6240 queue has been purged is it safe again to force the packet
6243 o If you send all packets immediately then it safe to send
6244 any of subsequent packets through the queue, however, after
6245 the first packet is put to queue then any subsequent packets
6246 must also be put to the queue.
6248 Follow these rules and everything works fine.
6250 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Added new function silc_server_remove_clients_by_server to
6253 remove all client entries from ID list when the server connection
6254 is lost. In this case it is also important to invalidate all
6255 client entires as they hold the invalid server entry. This
6256 fixes fatal bug when server has lost connection and will reconnect
6259 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Made some sanity checks to silc_server_daemonise like to check
6262 whether the requested user and group actually exists.
6264 * Added sanity check to SKE's silc_ske_responder_finish to check
6265 that the public and private key actually is valid.
6267 * Invalidate the client's nickname when receiving Replace ID
6268 packet and the Client ID is being replaced. This means that the
6269 server will query the nickname if someone needs it (client)
6272 * Sort the ID Cache in client library when the ID Cache data
6273 has changed (needs sorting).
6275 * Do not allow for SILC client to create several connections to
6276 several servers. The client does not support windows right now
6277 and generating multiple connections causes weird behaviour.
6279 Irssi-silc client does support windows and can handle several
6280 connections without problems, see: www.irssi.org and SILC plugin.
6282 * Fixed some places where client was added to the IDList. The
6283 rule of thumb is following (in order to get everything right):
6284 If the client is directly connected local client then the
6285 `connection' argument must be set and `router' argument must be
6286 NULL to silc_idlist_add_client function. If the client is not
6287 directly connected client then the `router' argument must
6288 bet set and the `connection' argument must be NULL to the
6289 silc_idlist_add_client function.
6291 * The funtion silc_server_packet_send_local_channel actually did
6292 not check whether the client was locally connected or not. It
6293 does that now. Fixed a bug related to LEAVE command.
6295 * Fixed Remove Channel User payload parsing bug in server's
6296 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6298 * The server's silc_server_save_channel_key now checks also the
6299 global ID list for the channel as it might not be in the local
6300 list. Fixed a bug related to LEAVE command.
6302 * Is this the end of the [<unknown>] buglet that has been lurking
6303 around for a long time? A little for loop fix in server's
6304 silc_server_command_whois_parse that is used by both IDENTIFY
6305 and WHOIS command. At least, this was a clear bug and a cause
6306 of one type of [<unknown>] buglet.
6308 * WHOIS and IDENTIFY commands call the function
6309 silc_server_command_[whois/identify]_check function even if
6310 we are not router server.
6312 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Added --with-gmp configuration option. If set the GMP
6315 is always compiled in the SILC source tree. If not set then
6316 it is checked whether the system has the GMP3 installed. If
6317 it has then the GMP won't be compiled (the system's headers
6318 and library is used), if it doesn't have it then the GMP is
6319 compiled in the SILC source tree.
6321 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Changed RSA private exponent generation to what PKCS #1
6324 suggests. We try to find the smallest possible d by doing
6325 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6326 not security fix but optimization.
6328 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Added new config entry [Identity] to fork the server and run
6331 it as specific user and group. A patch from Bostik.
6333 * Imported Dotconf configuration library into lib/dotconf.
6334 This will be used to create the SILC configuration files later.
6335 It will appear in the distsribution after this commit.
6337 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * A big code auditing weekend happening. Auditing code for
6340 obvious mistakes, bugs and errors. Also, removing any code
6343 Removed files for being obsolete:
6345 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6346 inline in the file lib/silcutil/silcbuffer.h)
6348 o lib/silcutil/silcbufutil.c (the header has inline versions)
6350 Changed code to fix possible error conditions:
6352 o The buffer formatting routines now check that the destination
6353 buffer really has enough space to add the data. This applies for
6354 both buffer formatting and unformatting
6355 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6356 unformatting was changed to accomodate following rules:
6357 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6358 sent to the function while XXX_*STRING will not allocate or copy
6359 the data into the buffer. Instead it sets the pointer from the
6360 buffer into the pointer sent as argument (XXX_*STRING used to
6361 require that the pointer must be allocated already). This change
6362 makes this whole thing a bit more consistent and more optimized
6363 (note that the data returned in the unformatting with XXX_*STRING
6364 must not be freed now). The routines return now -1 on error.
6366 o Tried to find all code that use buffer_format and buffer_unformat
6367 and added return value checking to prevent formatting and
6368 especially unformatting errors and possible subsequent fatal
6371 o Changed ske->x and ske->KEY to mallocated pointers in
6372 lib/silcske/silcske.h. Fixed possible data and memory leak.
6374 o Added return value checking to all *_parse* functions. Fixed
6375 many memory leaks as well.
6377 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6378 so that buffer overflows would not happen. All code now also
6379 checks the return value as it can fail.
6381 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Added reconnection support to server if the normal server looses
6384 its connection to the router (for example if router is rebooted).
6385 The server performs normal reconnection strategy implemented
6386 to the server. Affected file silcd/server.c.
6388 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Added new packet type SILC_PACKET_SET_MODE that is used to
6391 distribute the information about changed modes (for clients,
6392 channels and clients channel modes) to all routers in the
6393 network. Updated the protocol specification accordingly.
6395 Added functions into silcd/packet_send.c and
6396 silcd/packet_receive.c: silc_server_send_set_mode,
6397 silc_server_set_mode.
6399 Added new files silcmode.[ch] into lib/silccore that implements
6400 the encoding and decoding of Set Mode Payload. Added new type
6401 SilcSetModePayload. Moved the definitions of different modes
6402 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6404 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Oops, a little mistake in server's connection authentication
6407 protocol. The protocol is not ended with FAILURE but with
6408 SUCCESS if the authentication is Ok. :) Affected file is
6411 * Implemented NICK_CHANGE notify handling in server in the file
6412 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6413 the local clients on the channel. After the changing nickname
6414 in router environment snhould work and the [<unknown>] nickname
6415 should appear no more.
6417 The silc_server_replace_id function that receives the Replace ID
6418 payload now sends the NICK_CHANGE notify type also in the file
6419 silcd/packet_receive.c
6421 * Changed WHOIS and IDENTIFY command to support the maximum amount
6422 of arguments defined in protocol specs (3328 arguments). This
6423 fixed a bug that caused problems when there were more than three
6426 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Added extra parameter, command identifier, to the
6429 silc_client_send_command so that explicit command identifier
6432 Changed that ID list routines uses specific command identifier
6433 when sending WHOIS/IDENTIFY requests to the server so that they
6434 can be identified when the reply comes back.
6436 Affected files lib/silcclient/command.[ch],
6437 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6439 * Added `sender' argument to silc_server_packet_send_to_channel
6440 to indicaet the sender who originally sent the packet to us
6441 that we are now re-sending. Ignored if NULL. Affected file
6442 silcd/packet_send.[ch].
6444 * Added some server statistics support in silcd/server_internal.h
6445 SilcServerStatistics structure and around the server code. Also
6446 send some nice statistics information when client is connecting
6449 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Fixed channel ID decoding in server's JOIN command reply in
6452 silcd/command_reply.c
6454 * Fixed braodcasting of replace ID payload to not to send it if
6455 we are standalone server in silcd/packet_receive.c.
6457 * Fixed all channel message sending routines to not to send
6458 packets to clients that has router set, since they are routed
6459 separately in the same function earlier. Affects file
6460 silcd/packet_send.c and all channel packet sending functions.
6462 * In USERS reply, res_argv[i] are not allocated, the table
6463 is allocated. Thus changed that free the table, not its
6466 * In server's whois_check and identify_check if the client is
6467 locally connected do not send any WHOIS commands - they are not
6470 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Fixed some minor bugs in client when sending WHOIS command. The
6473 arguments was in wrong order.
6475 * Removed statis function add_to_channel from server in
6476 silcd/command.c that was previously used with the joining but
6479 * Tested USERS command in router environment successfully with two
6480 routers, two servers and two clients.
6482 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Reorganized the USERS command and command reply in client library
6485 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6486 When the command is given by user we register a pending command
6487 callback that will reprocess the command after the reply has been
6488 received from the server. When reprocessing the packet we then
6489 display the information. Thus, the USERS information is displayed
6490 now in the command callback instead of in the command reply
6491 callback. The processing of the command is same as previously
6492 when server has sent the command reply in the JOINing process.
6494 * Added to USERS command in silcd/command_reply.c to join the client,
6495 we didn't use to know about, to the channel after we've created
6496 a client entry for it. Also, for clienet we did know already still
6497 check whether it is on the channel or not and add it if not.
6499 * Removed silc_server_command_join_notify as the function and its
6502 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Changed the client's pending command handling to the same as the
6505 server's pending command handling. It is also now possible to
6506 execute command reply functions from other command reply
6507 function as the function callbacks for commands and command
6508 replies are one and same. The pending commands are not static
6509 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6510 in client connection context. Thus, pending commands are server
6511 connection specific as it is convenient.
6513 Changed the function silc_client_command_pending and
6514 silc_client_command_pending_del and added new function
6515 silc_client_command_pending_check. Removed the
6516 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6519 * Added cmd_ident, current command identifier, to the client
6520 connection context in lib/silcclient/client.h to keep track on
6521 command identifiers used in command sending. Client's command reply
6522 function handling now supports the mandatory command identifiers.
6524 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6525 funtions in client to fully support pending command callbacks.
6527 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6528 as one of the arguments to the application in the command reply
6531 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6532 before first releasing SILC but came back. Now it is removed again
6533 and should come back nomore. The FORWARDED flag was used only
6534 by the JOINing procedure by forwarding the command packet to router.
6535 Now, the JOINing procedure has been changed to more generic (due
6536 to various router environment issues) and FORWARDED is not needed
6537 anymore for anything. The protocol specification is yet to be
6540 Now, removed silc_server_packet_forward from server and the flag
6541 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6543 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Renamed NAMES command to USERS command. The NAMES was named that
6546 due to historical reasons. Now it is renamed. Also, rewrote
6547 parts of the USERS command. The nickname list is not sent anymore
6548 by the server. Only Client ID and mode lists are sent in the USERS
6549 command. Changed this also to the protocol specification.
6551 The client now resolves the names and stuff after it receives
6552 the USERS list from the server when joining to the channel.
6554 * WHOIS and IDENTIFY commands has been changed to support multiple
6555 Client ID's per command. One can now search for multiple users
6556 in the network by sending only one WHOIS or IDENTIFY command.
6557 Changed the code and the protocol specifications.
6559 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6560 uses silc_server_command_whois_parse to parse the request. */
6562 * If normal server, do not parse the WHOIS and IDENTIFY requests
6563 before sending it to the router. Saves some time.
6565 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Fixed JOIN command on client library. Wrong number of arguments
6568 used to crash the client.
6570 * Added silc_server_channel_has_global function to check whether
6571 channel has global users or not.
6573 * Added silc_server_channel_has_local function to check whether channel
6574 has locally connected clients on the channel.
6576 * The silc_server_remove_from_one_channel now checks whether the
6577 channel has global users or not after given client was removed from
6578 the channel. It also checks whether the channel has local clients
6579 on the channel anymore. If it does not have then the channel entry
6580 is removed as it is not needed anymore.
6582 * The silc_server_notify now checks on JOIN notify whether the joining
6583 client is one of locally connected or global. If it is global then
6584 the channel has now global users on the channel and that is marked
6585 to the channel entry. Also, it now saves the global client to
6586 global list who is joining and JOINs it to the channel. This is
6587 for normal server, that is.
6589 Changed silc_server_send_notify_on_channel,
6590 silc_server_packet_relay_to_channel and
6591 silc_server_packet_send_to_channel check if we are normal server
6592 and client has router set (ie. global client) do not send the
6593 message to that client, as it is already routed to our router.
6595 * Implemented LEAVE notify type handling in silc_server_notify
6598 * Tested LEAVE command in router environment successfully. Tested
6599 with two routers, two servers and two clients.
6603 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6605 * Implemented SIGNOFF notify type handling in silc_server_notify
6608 * silc_server_remove_id now removes the client entry from all channels
6609 it has joined and thusly sends SIGNOFF notify type.
6611 * Rewrote the NAMES list generation in server by removing two excess
6612 loops. The lists are created now inside one loop.
6614 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6616 * silc_server_remove_channel_user checks now also global list
6617 for channel and client.
6619 * silc_server_new_channel_user checks now both local and global
6620 list for channel and client. Fixed a bug in client id decoding.
6621 Used to decode wrong buffer.
6623 * silc_server_channel_message checks now both local and global
6624 list for channel entry.
6626 * Tested channel joining (hence JOIN) in router environment
6627 successfully. Tested with two routers, two servers and two
6630 * Tested channel message sending in router environment successfully.
6632 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Added silc_server_save_channel_key into server.[ch] to save the
6635 received channel key in Channel Key payload processing. It is
6636 also used in JOIN command reply handling.
6638 Equivalent function silc_client_save_channel_key added into
6639 client.[ch] into client library.
6641 * Changed JOIN command reply to send information whether the channel
6642 was created or not (is existing already) and the channel key
6643 payload. Changed protocol specs accordingly.
6645 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6646 the request was sent by ID and not by nickname. Crashed on
6649 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6652 now correctly save the received data.
6654 * silc_server_free_sock_user_data now notifies routers in the
6655 network about entities leaving the network.
6657 At the same time implemented functions silc_server_remove_id
6658 and silc_server_send_remove_id to receive and send REMOVE_ID
6659 packets. The packet is used to notify routers in the network
6660 about leaving entities. The ID removed will become invalid in
6663 * Added function silc_idlist_del_server into server. Removes and
6664 free's server entry from ID list.
6666 * silc_server_private_message function now checks, if we are router,
6667 that the destination ID really is valid ID, naturally.
6669 * In router when NEW_ID packet is received (for new client) the
6670 hash of the Client ID is saved in the ID Cache but the
6671 client->nickname is set to NULL, instead of putting the hash
6674 IDENTIFY command now also checks that client->nickname must be
6675 valid. If it is not if will request the data from the server who
6676 owns the client. Added new function
6677 silc_server_command_identify_check.
6679 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6680 to set the command to already allocated Command Payload.
6682 * Tested private message sending in router environment with two
6683 routers, two servers and two clients. Fixed minor bugs and now
6686 * Fixed segfault from client's NAMES command. Used to crash if
6689 * Forwarded packets must not be routed even if it is not destined
6690 to the receiver. Changed server code comply with this.
6692 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Added `require_reverse_mapping' boolean value to ServerParams
6695 structure. If TRUE (not default) the server will require that
6696 the connecting host has fully qualified domain name.
6698 If the reverse mapping is not required and hostname could not be
6699 found the IP address is used as hostname.
6701 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Implemented version string checking to both client and server.
6704 The check is incomplete currently due to the abnormal version
6705 strings used in development version of SILC.
6707 * Changed all command functions in server to use the new
6710 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Changed char *data to unsigned char *data in ID Cache system to
6713 support binary data as ID Cache data. Changed code to support
6714 binary data in lib/silccore/idcache.c.
6716 * Renamed silc_server_packet_relay_command_reply to
6717 silc_server_command_reply as it is normal packet receiving
6718 function. Rewrote the function to accept command replys for
6719 servers and not only for clients.
6721 * Mark remote router always as registered server if we are connecting
6722 to it. Otherwise, commands sent by the router to us are ignored.
6724 * All ID List find routines now returns the ID Cache Entry pointer
6725 as well if requested.
6727 * WHOIS command works now in router environment, tested with two
6728 routers, two servers and two clients.
6730 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6731 in router environment (as it is almost equivalent to WHOIS) but
6732 hasn't been tested thoroughly. Added new functions:
6734 silc_server_command_identify_parse
6735 silc_server_command_identify_send_reply
6736 silc_server_command_identify_from_client
6737 silc_server_command_identify_from_server
6739 * Disabled route cache adding because adding two different ID's with
6740 same IP replaces the old cache entry thus giving wrong route.
6741 The entry->router->connection is always the fastest route anyway
6742 so route cache may not be needed. Of course, new routes maybe
6743 established after receiving the ID when the entry->router->connection
6744 might not be anymore the most optimal.
6746 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6748 * Add route cache for received ID for fast routing.
6750 * Added silc_server_packet_route to route received packet on router
6751 that is not destined to us.
6753 * Renamed silc_server_get_route to silc_server_route_get.
6755 * Added id_string and id_string_len fields into SilcServer to
6756 include encoded ServerID for fast comparing without excess
6757 encoding of the ID's.
6759 * Cleaned up WHOIS command on server side. Added following static
6762 silc_server_command_whois_parse
6763 silc_server_command_whois_check
6764 silc_server_command_whois_send_reply
6765 silc_server_command_whois_from_client
6766 silc_server_command_whois_from_server
6768 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6769 arguments in command replies. All command functions should be
6770 updated to use this macro.
6772 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6774 * Minor typo fixes on command reply handling on server.
6776 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Added silc_server_command_add_to_channel internal routine to add
6779 the client to the channel after router has created the channel and
6780 sent command reply to the server.
6782 * Added generic silc_server_send_command to send any command from
6785 * Use static buffer with ID rendering instead of duplicating data.
6787 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed a channel user mode bug when joining to a channel server gave
6790 everybody channel founder rights, oops.
6792 * We mark ourselves as the router of the incoming server connection
6793 if we are router ourselves. This way we can check in some packet
6794 sending functions whether it is locally connected server. For
6795 incoming router connections we put NULL.
6797 * For router sending packets locally means now always sending the
6798 packet cell wide; to local clients and local servers. For normal
6799 server sending packet locally means sending it to only local
6802 * Fixed the JOIN command to really work in router environment. If the
6803 channel is created it is always created by the router. Router is
6804 also responsible of making the initial joining to the channel,
6805 sending JOIN notify to the sending server and distributing
6806 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6807 does not exist server doesn't do anything else but forward the
6808 command to the router which performs everything.
6810 * Added silc_server_send_channel_key function to send the Channel Key
6813 * Added silc_server_create_channel_key to create new channel key. The
6814 channel key is now re-generated everytime someone joins or leaves
6815 a channel, as protocol dictates. Note: channel->key_len is the
6818 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6821 packet_receive.[ch] to separate packet sending and receiving
6822 routines. The server.[ch] now includes everything else including
6823 actual packet processing (writing and reading data) and other
6826 Renamed silc_server_private_message_send_internal to
6827 silc_server_send_private_message. The routine is still though
6828 used only to relay private messages as server does not send
6829 private messages itself.
6831 Renamed silc_server_new_channel to silc_server_create_new_channel
6832 and added new function sicl_server_new_channel that handles the
6833 incoming New Channel packet. Added also new sending function
6834 silc_server_send_new_channel to send New Channel Payload.
6836 * Added new function silc_server_notify to process incoming notify
6837 packet to the server/router. Server may then relay the notify
6838 to clients if needed.
6840 * Added new function silc_server_new_channel_user to process incoming
6841 New Channel User packet. Router will redistribute the packet and
6842 send JOIN notify to its local clients and locally connected servers
6843 if needed. Normal server will send JOIN notify to its local client
6844 on same channel when received this packet. Added also corresponding
6845 sending function silc_server_send_new_channel_user to sent the
6848 * Added boolean route argument to send_notif_to_channel and
6849 packet_send_to_channel functions to attempt to route the packet
6850 if it is TRUE and send only locally if it is FALSE.
6852 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * silc_server_replace_id now broadcasts the received replace ID
6855 packet if it is not broadcast packet already. The router must
6856 broadcast to inform other routers about changed ID.
6858 * Added backpointer to server's router into SilcServer context in
6859 silcd/server_internal.h.
6861 * Fixed silc_server_packet_broadcast to send correct broadcast
6864 * The channel key is now distributed to the local client as soon
6865 as it is received from the router (in router environment) so that
6866 no other packet may be sent for the channel until client has
6869 * silc_server_remove_channel_user now broadcasts the received
6870 Remove Channel User packet if it is not broadcast packet already.
6871 The router must broadcast to inform other routers about removed
6874 * Added users field into SilcPacketContext that is a reference count
6875 of the context. One can increase the reference count by calling
6876 silc_packet_context_dup which is now changed to just increase the
6877 reference count instead of duplicating the data. The reference
6878 count is decresed by calling silc_packet_context_free that will
6879 free the data after the reference count hits zero.
6881 For now on the packet context and everything allocated into it
6882 (including the raw packet from network) must be freed by calling
6883 the new silc_packet_context_free function. Added also new function
6884 silc_packet_context_alloc that must be used now to allocate the
6885 context. This also means that if a routine is asynchronous from
6886 silc_[client/server]_packet_parse_type the packet context must
6887 be duplicated by calling silc_packet_context_dup. Otherwise it
6888 gets free'd after silc_[client/server]_packet_parse_type returns.
6889 Also, one must remember that if packet is duplicated then its
6890 reference count must be decresed by calling the free function as
6891 many times as it was duplicated.
6893 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6894 from both client and server.
6896 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6898 * Made joining to a channel working in router environment.
6900 * Cleaned up JOIN command on server side and create function
6901 silc_server_command_join_channel internal routine to make the
6904 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Changed silc_command_pending list to SilcDList. Also, added
6907 `ident' field to SilcServerCommandPending structure to identify
6908 the reply and to call correct callback.
6910 Added silc_server_command_pending_check function to replace the
6911 corresnponding macro. The silc_command_pending list is not
6914 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6915 to set identifier to previously allocated Command Payload. It
6916 is used to set identifier for command when resending Command
6919 * Added silc_command_payload_encode_payload to encode Command
6920 Payload buffer from SilcCommandPayload structure.
6922 * Added silc_argument_payload_encode_payload to encode Argument
6923 payload buffer from SilcArgumentPayload structure.
6925 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6927 * Changed WHOIS command to support router connection on server side.
6928 The whois request is always sent to router unless the server is
6929 standalone server. After server has received the reply from the
6930 router will it send the reply to the client.
6932 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6933 broadcast received broadcast packet. The function is used only
6934 by router. The broadcast packet is always sent to the router's
6937 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6938 render given ID to printable string, for log files for example.
6940 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Made basic router to router connections working. At least they
6943 can now connect to each other but nothing really works the way
6944 they are supposed - yet.
6946 * Added new initiator token to RouterConnection configuration
6947 file in silcd/serverconfig.[ch]. It is used to tell whether we
6948 are the initiator to the remote router or whether we'll expect
6949 the other end to connect.
6951 * Moved registering of listener task to silc_server_init, hence
6952 the server starts listenning as soon as it is run, even if it
6953 does not have connections to other routers. Let's see how well
6956 * Changed default connection retry timeouts for more suitable in
6959 * Removed cipher and such arguments from silc_idlist_add_client
6960 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6961 Added new function silc_idlist_add_data to add the keys and stuff
6964 * Added SilcIDListData structure and added it to SilcClientEntry
6965 and SilcServerEntry as their first field in the structure. This
6966 way we can explicitly cast the ID entries to the SilcIDListData
6967 structure and get common data for the entries. In past, we had
6968 to first check what type of connection it is and then cast it to
6969 correct ID entry type. Now, we can directly cast the opaque
6970 pointer to the SilcIDListData (no matter what ID entry it actually
6971 is) and get the data needed.
6973 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6976 in some circumstances even if threre were timeout tasks, though not
6977 IO tasks, but tasks anyway. Now fixed.
6979 * Defined SilcServerConnection structure to hold connection specific
6980 stuff about directly connected servers and routers. The definition
6981 is currently in silcd/server_internal.h. I thought about having
6982 a bit more important role fro this struct but for now it is used
6983 only when connecting to other server (or router actually).
6985 * Added connecting retry support in server when connecting to
6986 router(s). The retry feature implement exponential backoff
6987 algorithm. Also, added SilcServerParams structure to hold default
6988 parameters for server. For now, it include these retry settings
6989 and are hard coded. After server is moded to be as Silc Server
6990 Library this structure will be more important.
6992 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Changed client librarys channel->clients table to SilcList and
6995 changed code accordingly.
6997 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Changed client's channel table to SilcList and changed code
7000 accordingly. Also changed SilcChannelClientEntry to include back-
7001 pointer to the channel so that client entry can use that structure
7002 as list as well and we have fast cross-reference to the channel.
7003 This change dramatically decreased the complexity of channel
7004 handling with client entry and vice versa (removed one extra
7005 loop when searching for channel entry from many functions).
7007 * Changed server->sim from table to SilcDList and changed code
7010 * NAMES command can now be used from user interface. It will show
7011 the user list on the channel, neatly.
7013 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7014 Code now saves realname of the user if it becomes available.
7016 * Renamed configure.in to configure.in.pre and made ./prepare
7017 script to automatically add correct version string to
7018 configure.in which it creates from configure.in.pre.
7020 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * NAMES command reply now shows users mode with the nickname when
7025 * Moved silc_client_ch[u]mode[_char] functions from
7026 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7027 place sucks, they are utility functions and should be in some
7030 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7032 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7035 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Added TRQ (efficient deque and list library) into lib/trq. This is
7040 a very good list library that is currently used in the SILC. Defined
7041 SilcList API over the library because I didn't like the API very
7042 much. See lib/trq/silclist.h for the API and examples of how to
7043 use the API. Fixed various places in the code to use the new
7044 SilcList API. The SilcList is meant for lists that has a structure
7045 already defined as a list. It is not suitable to add just some
7046 context to the list (in TRQ, the context is the list actually).
7048 So, I defined SilcDList that can be used for the purpose where
7049 predefined list structure does not exit. This can be used as
7050 such list. Now some context just can be added to the SilcDList.
7051 Currently this list is not used in the SILC just yet, though there
7052 are a lot places where this can replace dynamically allocated
7053 tables and I will fix these places, later, to use SilcDList.
7054 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7055 and use TRQ internally).
7057 Also fixed some annoying warning messages that the original TRQ
7058 code generated. Also minor changes to TRQ's Makefile.in.
7060 * Added support for querying by Client ID to both WHOIS and
7061 IDENTIFY commands into server, as required by the protocol.
7063 * Removed method function pointers from SilcBuffer structure. They
7064 weren't used to anything and just increased the context size for
7065 no good reason. This change also made silc_buffer_alloc and
7066 silc_buffer_free functions inline functions.
7068 * Disabled command flooding detection support until it's fixed so
7069 that it accepts commands in but does not execute them more than once
7072 * Added silc_net_localhost(), to return local hostname, into
7073 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7074 that must be initialized before calling silc_client_init.
7076 * Added new function: silc_server_send_notify_on_channels to send
7077 notify messages to all channels client has joined. It is assured
7078 that the message is sent only once per client.
7080 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7081 lib/silcutil/silcutil.[ch] as silc_format function. The new
7082 function is generic and is used by server as well, not only by
7083 the logging routines.
7085 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7086 the provided version string was not acceptable. Added new function:
7087 silc_ske_check_version into lib/silcske/silcske.h. The function
7088 must be implemented by the application (client or server) and it
7089 does not reside in the SKE library. The function checks the version
7090 string remote end sent.
7092 * Added back pointers (to opaque context and to SilcSocketConnection)
7093 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7095 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7096 duplicate packet context structure.
7098 * Changed `notify' client operation to send same arguments as client
7099 receives from server except for ID's. ID's are mapped to correct
7100 ID entry and that is returned. Also, if channel entry is not sent
7101 by server but the notify is for channel the channel entry is sent
7102 to application (otherwise application doesn't know that it is for
7103 channel (library gets it from packet's Destination ID)).
7105 * Added silc_client_remove_from_channels into client library to
7106 remove a client from all channels it has joined to. Used when
7107 received SIGNOFF notify from server. Added also new function
7108 silc_client_replace_from_channels to replace old ID entry with
7109 new ID entry on all channels. Used when received NICK_CHANGE
7112 * Fixed ID Cache list handling in silc_idlist_get_client in
7113 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7114 to get (or query) client by ID.
7116 * Updated TODO list.
7118 * Added connection authentication status message defined by the
7119 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7120 support for these into the code in client and server side.
7122 * Added generic function silc_client_send_command to send any command
7123 with variable argument list. Application should use this function
7124 to send commands if the command functions provided by the library
7125 does not suite for the application's user interface needs.
7127 * Added new `failure' client operation. Application is notified about
7128 received failure packet if client is executing a protocol. In this
7129 case the protocol's execution has failed.
7131 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7132 is required by the protocol.
7134 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7135 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7138 * Added status flag to SilcSKE object to indicate realtime status
7139 of the SKE protocol.
7141 * Application receives now exactly same command reply arguments as
7142 the library receives from server. However, if ID is received the
7143 corresponding ID entry is returned to the application (eg. Client
7144 ID is mapped to correct SilcClientEntry entry and that is returned).
7145 Changed command_reply client operation due to this change.
7147 * Changed all ID's in commands and in command replys as ID Payloads.
7148 Change affected both client and server side codes.
7150 All ID's sent in SILC network (with execption of ID's in SILC
7151 Packet header) are sent in ID Payload to support variable length
7154 * Server now notifies nick changes and notifies all clients on
7155 the channels about the new nickname (about the new Client ID,
7158 * Implemented CMODE command to change channel modes. Supports all
7159 channel modes defined by the protocol specs except ban and invite
7160 lists. (Also, private channel key mode is supported but support for
7161 setting private channel key in client is missing, thus, this mode
7162 has no effect on client side (except that server requires that the
7163 client uses private channel key and normal channel traffic does not
7166 Also, invite mode works per se, but INVITE command does not work
7167 yet correctly, so you can set channel as invite only channel but
7168 inviting clients to the channel does not work (it is yet to be
7169 thought what's the best way to do it).
7171 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7172 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7173 Implemented CUMODE command to change user's mode on the channel.
7174 Supports all modes defined by the protocol specs.
7176 * Added NAMES command reply to return users modes on the channel.
7178 * Removed unnecessary and slow ciphers from lib/silccrypt.
7180 * Set SO_KEEPALIVE option to connection sockets by default.
7182 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7184 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7185 redefined the Notify Payload into protocol specs.
7187 * Added silc_id_payload_parse_id to get ID directly from raw
7190 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7192 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7193 accept searching by Client ID as well.
7195 * Added support for LEAVE and SIGNOFF notify types in client library.
7197 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7198 to parse ID Payload from raw data.
7200 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Added flags parameter into silc_ske_assemble_security_properties
7203 function in lib/silcske/silcske.[ch].
7205 * Changed notify client operation to fit better for notify messages
7206 sent by server. The notify payload received from server is now
7207 passed to the application (after parsing it to SilcNotifyPayload).
7208 It is application's responsibility to retrieve the arguments
7209 from the payload and show the message the way it wants. The message
7210 sent by server is implementation specific.
7212 * Changed public keys to comply with the protocol specification.
7213 Old public keys are not supported anymore and are not compatible.
7215 * Removed nickname from Channel Payload as the latest draft removed
7216 it. The client must resolve the nickname from the NAMES command
7217 reply received when it joined the channel.
7219 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7221 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Fixed some errors in protocol specification drafts.
7225 * Created lib/silccore/silcnotify.c to implement Notify Payload
7226 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7227 generic payloads described by protocol specifications. The file
7228 includes implementations for ID Payload and Argument Payload.
7230 * Changed Command Payload implementation to use the new Argument
7231 Payload. Changed command_xxxx_payload to command_payload_xxxx
7232 to comply with SILC coding conventions.
7234 * Added suppport for Argument Payload handling in Notify Payload
7235 implementation as protocol requires it. Added the new support
7236 into server and client lib as well.
7238 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Added support for multiple nicknames on same channel. [n] is
7241 added locally to the nickname if there are more than one same
7242 nicknames on the channel.
7244 * Server now sends all nicknames that matched WHOIS request.
7245 Client also shows the list received from server.
7247 * Added TOPIC command to client side. User can now set and show
7248 current topic on channel.
7250 * Added MOTD command to client and server. Also, server sends the
7251 motd when client connects to the server.
7253 * Changed version strings to comply ISO 8601.
7255 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7257 * Fixed protocol error handling in client library. It should now
7258 cope even if the SKE fails for some reason.
7260 * Made new protocol specification drafts for submitting to IETF.
7262 * Implemented TOPIC command to server in silcd/command.c.
7264 * Added two new notify types into lib/silccore/silcnotify.h:
7265 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7266 notify nickname change and topic setting/change on a channel.
7268 * API change of command_reply operation in client library. The
7269 application gets now the status type received from server as well.
7271 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7275 * Cras fixed and optimized the packet handling even further and
7276 it should work now. Minor change to the prototype of function
7277 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7279 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7281 * Added new function into lib/silcutil/silcschedule.[ch]:
7282 silc_schedule_with_fd to select() a specified fd. The function
7283 returns after timeout expires or data arrives or goes. The
7284 function is used by packet routines to wait that all data is
7285 received from network.
7287 * Fixed data reading from network in lib/silccore/silcpacket.c.
7288 The code now assures that all data is read from the fd and then
7289 continues packet processing. This was a bug fix since the code
7290 used to drop some data in some circumstances.
7292 * Added new function into lib/silcclient/client.[ch]:
7293 silc_client_start_key_exchange to start key exchange after
7294 connection has been established to server. The code internally
7295 now uses this funtion but its main purpose was to provide it
7296 for applications that perform their own connecting. After
7297 application has created a connection it merely calls this
7298 function to start the key exchange between client and server.
7299 The library takes care of everything else after that.
7301 Updated also lib/silcclient/README to explain the usage of
7304 * Do not send to application information that connection has
7305 been established. Application gets notified it by connect
7308 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Applied cras's patch to add silc_schedule_one function. The
7311 function runs scheduler once and returns.
7313 * Fixed the scheduler after cras messed it up. The timeout
7314 handling works now as it's supposed to work.
7316 * Added into lib/silccore/ silcnotify.h to include notify
7317 message types support. Changed silc_server_send_notify*
7318 functions, in server.[ch], to support those new notify types.
7319 Added the support for the notify types into client library,
7320 as well. Added new notify client operation into ops.h in
7323 * Changed silc_server_packet_send_to_channel to send normal
7324 packets instead of just channel message packets. The function
7325 is now used to send the notify packets to channels. It is not
7326 used to send channel message packets anymore, as server never
7329 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7330 va_arg()s as it seems to require it nowadays. I guess, if SILC
7331 is compiled with older va_arg() the new code should work anyway.
7333 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7335 * Splitted core library. Core library (lib/silccore) includes
7336 now only SILC protocol specific core (and common) components.
7337 Created new utility library (lib/silcutil) that includes more
7338 generic purpose stuff. The stuff for util library was taken
7339 from the old core library. This was minor and easy split.
7341 * Created SILC Client Library (lib/silcclient) that includes
7342 implementation of the SILC client without user interface. This
7343 was major move from silc/ directory. The code has been changed
7344 so that it is transparent towards the user interface. The
7345 silc/ directory includes now the same user interface as before
7346 and it uses the new client library. Read lib/silcclient/README.
7347 Basicly, the client library performs everything else related
7348 to SILC except user interface handling. Also, configuration
7349 files are considered to be part of user interface and library
7350 does not handle them.
7352 This change also changed a lot of structures, function naming etc.
7353 Most important change was that SilcClientWindow object was
7354 renamed to SilcClientConnection in the client library. Created
7355 also new file lib/silcclient/ops.h. Also added new files
7356 silc/local_command.[ch] and silc/client_ops.[ch].
7358 All these changes were made to make it easier for user interface
7359 designers to create what ever user interface for the SILC client
7362 It is also expected that the server will be moved to lib
7363 directory as well and SILC Server Library will be created;
7364 sometimes in the future.
7366 * Removed Local commands from lib/silccore/silccommand.h as
7367 they are application specific and new client library does not
7368 handle any of those anymore.
7370 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7371 old client implementation in silc/.
7373 * Added support for callback functions in SILC_LOG_* macros.
7374 Application can now set its own callbacks that will be called
7375 instead of using the default functions that will always print
7376 the debug messages to stderr (or stdout). Also, debugging can
7377 now be disabled by setting silc_debug to FALSE and re-enabled by
7378 setting it to TRUE. Note, that logging will still work even
7379 if debugging is disabled.
7381 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7382 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7383 silc_log_reset_debug_callbacks.
7385 * To enable debugging in silc client one must give now -d
7386 option on command line.
7388 * Changed silc_schedule_init to automatically allocate task queues
7389 if they are not allocated before calling it.
7391 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7393 * Added GMP 3.1 into math library.
7395 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7398 a channel in SILC network. The packet is used by servers and
7399 routers to notify other routers that user has left a channel.
7400 This little feature was missing until now. Added the feature
7401 to protocol specification as well.
7403 Added functions: silc_server_send_remove_channel_user and
7404 silc_server_remove_channel_user into server.[ch].
7406 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7407 lib/silccore/silcpacket.h. However, they are not implemented
7410 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Fixed joining to a channel and sending channel messages
7413 between server and router. The channel message sending should
7414 now work inside a cell.
7416 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Fixed the private message sending between server and router.
7419 The private message sending should now work inside a cell.
7421 * Added silc_server_replace_id into server.[ch] to replace
7422 existing ID in the SILC network.
7424 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7425 and silc_idlist_replace_server_id into idlist.[ch] in server.
7427 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7429 * Fixed the server to server connections. Server can again now
7430 connect to router. Router to router connections probably does
7433 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7435 * Added dynamic protocol registering support. Now protocols can
7436 registered and unregistered on the fly. Patch by cras.
7438 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7440 * Added lib/contrib directory to hold routines that some platforms
7441 don't have but are needed by SILC.
7443 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7444 into lin/contrib to provide getopt() and getopt_long() for
7445 those who don't have it.
7447 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Added AWAY command to client. When away message is set and
7450 client receives a private message packet the client automatically
7451 replies to the sender with the away message.
7453 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7454 bug seemed to be the cause of recent problems when compiling
7457 * Added version detection support to SKE protocol specification
7458 and added the new changes to the SKE implementation as well.
7459 There were other minor changes in the SKE protocol as well.
7461 Many changes in lib/silcske/silcske.[ch] and in
7462 lib/silcske/payload.[ch].
7464 * Added ^U functionality, clear input line. Patch from cras.
7466 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Mainly small bugfixes on core library. Fixed some debugging
7469 logging and buffer overflow in silclog.c.
7471 * Updated config.sub and config.guess on the distribution tree.
7473 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7475 * Added command lagging support in server. Client may execute
7476 commands now only once in two seconds.
7478 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7480 * Optimized packet reception. MAC computation and checking is now
7481 also more optimized. A lot previously duplicated code is now
7482 used as generic by both client and server.
7484 * Fixed key pair generation in clientutil.c
7486 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * Added into lib/silccore/silcbufutil.[ch] new function;
7489 silc_buffer_realloc.
7491 * Moved generic packet sending/encryption functions to
7492 lib/silccore/silcpacket.[ch] from client and server. Some
7493 rewriting of the functions.
7495 * Moved all generic packet reception/decryption functions to
7496 lib/silccore/silcpacket.[ch] from client and server. The
7497 packet processing is now much cleaner in both client and server.
7498 These were major changes in both client and server.
7500 * Created many common functions in server to do packet sending.
7501 Previously code were duplicated a lot, this has been removed
7504 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Rewrote major parts of the ID cache system. Don't know
7507 whether it is better now or not but at least the API is more
7510 * Major rewrite on ID cache stuff on client because of the ID
7511 cache API changes. Added idlist.c to client.
7513 * Also major rewrite on ID cache stuff on server as well.
7514 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7515 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7516 in hand, instead they are all put into the ID cache system now.
7517 All server_idlist_* routines uses ID cache now instead of
7518 traversing its own lists (those lists does not exist anymore).
7519 SilcIDList though still exists. Also, SilcXXXEntry's are
7522 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Finally made the SKE implementation compliant to the protocol
7525 specification. All mp integers are now binary encoded as
7526 opposed being HEX encoded.
7528 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7531 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7532 functions: silc_[encode/decode]_pem. Also added function
7533 silc_encode_pem_file to PEM encode with newlines ('\n') for
7536 * SILC public keys are now encoded either PEM or binary. Same
7537 option is for private keys as well. By default private keys
7538 are binary encoded and public keys PEM encoded. Silly HEX
7539 encoding were removed.
7541 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7542 function to create fingerprints.
7544 * Fixed a bug in SHA1; does not change the original data anymore.
7546 * Partly implemented INFO command on client and server side.
7547 Fixed CLEAR command. Changes to SERVER command; show current
7548 server(s) when giving command without arguments. Added
7549 VERSION command to client.
7551 * Added check to server that unregistered connections cannot
7552 execute commands (unless it is specificly allowed).
7554 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Fixed screen refresh.
7558 * Fixed channel joining bug from client. On some circumstances
7559 client tried to join to a channel it had already joined.
7561 * Added public key verification process into client's protocol.c.
7562 The client now verifies the public key from user and saves
7563 it into ~./silc/serverkeys/ directory.
7565 Added into: clientutil.[ch]: silc_client_verify_server_key.
7567 * Changed SKE protocol's silc_ske_initiator_finish function
7568 to accept callback function that verifies the received public
7569 key. Removed old silc_ske_verify_public_key function.
7571 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7573 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7574 silc_pkcs_private_key[_data]_set.
7576 * Made the password and public authentication more cleaner in
7577 server's protocol.c.
7579 * Removed historic and obsolete protocol `channel_auth' from
7580 both client and server.
7582 * Removed wrong way of sending command status messages from
7583 server to client in server's command.c. The old way violated
7584 protocol specification.
7586 Changes to silccore/silccommand.[ch]: removed
7587 silc_command_encode_status_payload -> not needed anymore,
7588 changed silc_command_encode_payload_va to accept extra
7589 argument on variable argument list. The argument type must
7590 now be provided to the function. Also, added new function:
7591 silc_command_encode_reply_payload_va which is same as
7592 normal command_encode_payload_va except command status type
7593 is provided as extra argument.
7595 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Added ~./silc directory handling. The directory includes the
7598 public and private keys for the client.
7600 Added silc_client_check_silc_dir, silc_client_create_identifier
7601 and silc_client_load_keys.
7603 * Implemented SILC protocol compliant public key. Added public
7604 and private key saving to and loading from files.
7606 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7607 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7608 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7609 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7610 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7612 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7613 silc_pkcs_load_[public/private]_key.
7615 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Added silc_server_get_route (route.[ch]) to get connection
7618 data for the fastest route for given ID.
7620 * Implemented INVITE command on client and server. The command
7621 were re-defined in the SILC Protocol Specification and the
7622 implementation now complies with the specification.
7624 * Implemented PING command on client and server.
7626 * Implemented NAMES command on client and server. The server side
7627 supports currently only normal server not router server yet.
7628 Some changes to NAMES definition in SILC protocol specification.
7630 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Implemented LEAVE command on client and server.
7634 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7635 again. This change was made to the protocol as well. Server
7636 should not violate the protocol specification anymore.
7638 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7641 was tested. SOCKS4 was not but should work anyway.
