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

591 Affected files silcd/serverconfig.[c], server.[c].
593 * Splitted the doc/example_silcd.conf.in. Separated the crypto
594 algorithm parts and created new file silcalgs.conf, that
595 is now included from the example_silcd.conf.in.
597 * Optimized the silc_server_connect_to_router_second to take
598 the connection configuration object from the SilcServerConnection
599 object instead of finding it during the connecting phase.
600 Added the configuration object to SilcServerConnection struct.
601 Affected files silcd/server_internal.h, server.c.

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

683 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
685 * Fixed the file transfer's key agreement payload to include
686 zero port also if the hostname is NULL because it could not
689 Call file transfer monitor callback now also if error occurs
690 during key agreement protocol.
692 Changed the silc_client_file_send interface to return the
693 SilcClientFileError instead of session id. The session ID
694 is returned into pointer provided as argument.
696 Check that the file exists locally before sending the
697 file transfer request at all.
699 Affected file lib/silcclient/client_ftp.c, silcapi.h.

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

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

748 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
750 * Fixed private message handling. It used some old code that
751 caused the client to crash. Affecte file is
752 lib/silcclient/client_prvmsg.c.
754 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
756 * Added function silc_client_add_channel,
757 silc_client_replace_channel_id, and removed functions
758 silc_client_new_channel_id and silc_idlist_get_channel_by_id
761 * Added cross reference of the joined channels to the
762 SilcClientEntry, and changed the SilcChannelEntry's
763 users list to SilcHashTable. The affected files are
764 lib/silcclient/idlist.[ch].
766 * Fixed a bug in hash table tarversing. While the hash table
767 is traversed with SilcHashTableList the table must not be
768 rehashed. It is now guaranteed that auto rehashable tables
769 are not rehashed while tarversing the list. Also defined that
770 silc_hash_table_rehash must not be called while tarversing
771 the table. Added function silc_hash_table_list_reset that must
772 be called after the tarversing is over. The affected files are
773 lib/silcutil/silchashtable.[ch].
775 * Changed all hash table traversing to call the new
776 silc_hash_table_list_reset in server and in client library.
778 * Added function silc_client_on_channel to return the
779 SilcChannelUser entry if the specified client entry is joined
780 on the specified channel. This is exported to application as
781 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
783 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
785 * Fixed founder regaining problem with JOIN command on normal
786 server. The notify for mode change must be sent always and
787 not only if !cmd->pending. Affected file silcd/command.c.
789 * Fixed the WHOWAS command's reply sending to support the
790 lists correctly. Affected file silcd/command.c.
792 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
794 * When sending JOIN command to router for processing the
795 sender's old command identifier was not saved back to the
796 sender's command context, fixed now. The affected file is
799 * Create the key in JOIN command of the router did not return
800 the channel key, added check for this. Affected file is
803 * Fixed a channel ID update bug in JOIN command reply. Do
804 not directly upgrade the ID but call the function
805 silc_idlist_replace_channel_id if the ID was changed.
806 Affected file silcd/command_reply.c.
808 * Fixed memory leaks from command calling if it would fail.
809 Affected file silcd/command.c.
811 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

815 Memory leak fixes around libaries, irssi window resize fix,
816 new silclist.h and silcdlist.h, all extern inline changed to
819 * Removed dotconf from lib/dotconf, not needed anymore.
821 * Removed TRQ from lib/trq, not needed anymore.
823 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
824 with server connections. Later this will be configurable
825 in config file after new config file is done. Affected file
828 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
830 * Fixed a crash in server related to channel announcements.
831 Affected file silcd/server.c.
833 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Fixed memory leaks in silc_server_create_new_channel*
836 functions. Affected file silcd/server.c.
838 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
839 which ID was changed. This way the router will send the
840 user list for the channel again, and server won't be in
841 desync in some rare circumstances. Affected file is
842 silcd/packet_receive.c.
844 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
846 * Check for NULL socket pointer in the function

855 * Fixed some header addition to Toolkit distribution in
856 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
858 * Added lib/silcclient/client_ops_example.h as an template
859 file for application programmers to quickly start using
860 the SilcClientOperation functions in their application.
861 Updated the lib/silcclient/README as well to tell about this
862 nice file made available.
864 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
866 * Call silc_server_remove_from_channels when removing client
867 entry when NO_SUCH_CLIENT_ID was received. Affected file
868 is silcd/command_reply.c.
870 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * Added server & router operator statistics updating. Affected
873 file silcd/packet_receive.c and silcd/command.c.
875 * Fixed the SERVER_SIGNOFF notify handling on normal server
876 not to save the history information for clients. Same was
877 fixed earlier in remove_clients_by_server function, but not
878 here. Affected file silcd/packet_receive.c.
880 * Raised the default connection-retry count from 4 to 7 in
881 server. Affected file silcd/server.h.
883 * Cancel any possible reconnect timeouts when we start the
884 key exchange. Affected file silcd/server.c.
886 * Do not reconnect on connection failure when SCONNECT was
887 given. Affected files silcd/server.[ch].
889 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
893 * Fixed the NICK command to always give the unformatted
894 nickname to the one giving the NICK command. If unformatted
895 nickname is cached already it will be formatted and the
896 local entry will always get the unformatted nickname.
897 Affected file lib/silcclient/idlist.c.
899 * Fixed some double frees from client library commands.
900 Affected file is lib/silcclient/command.c.
902 * Fixed CUMODE command in server to assure that no one can
903 change founder's mode than the founder itself, there was a
904 little bug. Affected file silcd/command.c.
906 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Removed the SilcClientCommandDestructor from the client
909 libary, it is not needed anymore. Affected files are
910 lib/silcclient/silcapi.h, command[_reply].[ch],
911 client_notify, idlist.c.
913 * Fixed GETKEY command to first resolve client, and then
914 resolve the server only if the client was not found, instead
915 of resolving both at the same time. Affected file is
916 lib/silcclient/command.c.
918 * Added silc_client_start_key_exchange_cb and lookup the
919 remote hostname and IP address before starting the key
920 exchange with server. The affected file is
921 lib/silcclient/client.c.
923 * The server's public key is now saved using the IP address
924 of the server and not the servername for the filename.
925 The hostname public key filename is checked as an fall back
926 method if the IP address based filename is not found.
928 Fixed the GETKEY command to save the fetched server key
931 Print the remote server's hostname now when new key is
932 received during connection process. Affected file is
933 irssi/src/silc/core/client_ops.c.
935 * Return always our own public key to the client if it asks
936 for it with GETKEY command. Affected file silcd/command.c.
938 * Removed the use_auto_addr variable from default config
939 file since it was in wrong section. Affected file is
942 * Fixed TOPIC_CHANGE notification to not route it when it
943 was sent using silc_server_send_notify_to_channel function.
944 Affected file silcd/command.c.
946 * Fixed silc_server_send_notify_kicked to send the kicker's
947 Client ID also, it was missing. Affected files are
948 silcd/command.c, silcd/packet_send.[ch].
950 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Do not save client history information in SERVER_SIGNOFF.
953 Fixes the bug in normal server that it does not detect
954 the client becoming valid after the server becomes back
955 online. Affected file silcd/server_util.c.
957 * Added `sock_error' field into the SilcSocketConnection
958 context. When error occurs during socket operation (read
959 or write) the error is saved. Added also new function
960 silc_socket_get_error to return human readable socket error
961 message. Affected files are lib/silcutil/silcsockconn.[ch],
962 lib/silcutil/unix/silcunixsockconn.c, and
963 lib/silcutil/win32/silcwin32sockconn.c.
965 * The server now prints the socket error message in the
966 signoff for client. Affected file silcd/server.c.
968 * Fixed the `created' channel information sending from router
969 to server in JOIN command. Checks now whether the channel
970 really was created or not and set it according that.
972 Fixed the JOIN command to use the client entry's current
973 ID during the joining procedure instead of the one it sent
974 in the command (it is checked though), since it can change
975 between the packet processing and command processing, and
976 would just case unnecessary pain in the client end. Affected
977 file silcd/command.c.
979 * Fixed a channel key payload sending to use correct channel
980 ID when the server was forced to change the channel's ID by
981 router. Router sent the key payload with the old Channel ID.
982 Affected file silcd/packet_receive.c.
984 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
986 * Call silc_server_save_channel_key only if the key payload
987 was provided in the JOIN command's command reply. Affected
988 file silcd/command_reply.c.
990 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
992 * Fixed silc_mp_sizeinbase to return the value correctly with
993 MPI. Affected file lib/silcmath/mp_mpi.c.
995 * Fixed the stop_server signal to correctly stop the scheduler
996 and gracefully stop the server when SIGTERM or SIGINT signals
997 are received. Affected file silcd/silcd.c.
999 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1001 * Simple handling of TERM and HUP signals. Also added some log
1002 flushing call around. Affected file is
1005 * Fixed small bugs in silclog.c. Now buffering output will take
1006 effect after 10 seconds since startup: This will ensure that
1007 no important startup messages are lost. Also output redirection
1008 will preserve original format ([Date] [Type] message).
1009 Affected file is lib/silcutil/silclog.c.
1011 * Added two options to the config file, in the logging section:
1012 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1013 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1015 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Do not print the warning about log files not being initialized
1018 more than once to avoid excess logging. Affected file is
1019 lib/silcutil/silclog.c.
1021 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1022 the SIM copying in make install in Makefile.am.pre.
1024 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1026 * Rewritten silclog APIs. Globally interesting changes follows:
1027 silc_log_set_files() changed to silc_log_set_file().
1028 silc_log_set_callbacks() changed to silc_log_set_callback().
1029 ROBOdoc documented silclog header file.
1030 SilcLogCb now returns bool to wether inihibit the default
1031 handler or not (to keep the old behaviour return always TRUE).
1032 The new APIs should also fix the problem of the
1033 silcd_error.log file that was written in the current directory.
1036 Log files streams will remain opened after silc_log_set_file()
1037 call, means less CPU usage notably on high traffic servers.
1038 File streams are now full buffered, and flushed to the disk
1039 every 5 minutes, lesses HD activity and CPU usage.
1040 Messages can be redirected, allowing admins to configure
1041 one single logfile for all server messages.
1042 the silc_log_quick global variable to activate fast-logging.
1043 Affected files lib/silcutil/silclog.[ch]
1045 * Changed some code to conform new silclog APIs. Affected
1046 files are doc/example_silcd.conf.in, silcd/server.c
1047 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1050 * Fixed a memory leak that could occur in some situations.
1051 Affected file silcd/serverconfig.c.
1053 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1055 * Added the silc_client_del_client to remove the client from
1056 all channels as well. Affected file lib/silcclient/idlist.c.
1058 * Fixed the client library to correctly remove the client
1059 from all channels when the client entry is being destroyed.
1060 Affected file lib/silcclient/client_notify.c, command.c.
1062 * Added auto-nicking support to the client library. If the
1063 applicatio now sets client->nickname it will be sent to the
1064 server after connecting by the library. This way for example
1065 SILCNICK (or IRCNICK) environment variables will have effect
1066 and always change the nickname automatically to whatever
1067 it is wanted. Affected file lib/silcclient/client.[ch].
1069 * Renamed silc_server_command_bad_chars to the
1070 silc_server_name_bad_chars and moved it to the
1071 silcd/server_util.[ch]. Added also new function
1072 silc_server_name_modify_bad to return nickname that
1073 includes bad characters as new nickname without those
1074 bad characters. This check and modify is now used in
1075 silc_server_new_client when the username is initially set
1076 as nickname, so it must be checked to be valid nickname.
1077 Affected file silcd/packet_receive.c.
1079 * The nickname length is now taken from the packet for real
1080 and not trusted to strlen() since it clearly can return
1081 wrong length for nickname including bad characters. This
1082 also applies to channel names. Affected file silcd/command.c.
1084 * Removed the lib/silcsilm/modules directory. Modules are now
1085 compiled into the lib/silcsim. Fixed the copying of the
1086 modules to follow symbolic links in Makefile.am.pre.
1088 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1090 * Fixed silc_string_regexify list creation. Fixes bugs with
1091 BAN and INVITE commands in server. The affected file is
1092 lib/silcutil/unix/silcunixutil.c.
1094 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Removed the command destructor entirely from the server's
1097 command and command reply routines. It is not needed, and
1098 its usage was buggy and caused crashes. Affected files are
1099 silcd/command[_reply].[ch].
1101 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Cancel protocol and NULL sock->protocol if timeout
1104 occurred during protocol. Affected file silcd/server.c.
1106 * Cancel protocol timeouts always before calling the final
1107 callback, to assure that after final callback is called
1108 no other state will be called for the protocol anymore.
1109 Affected file silcd/protocol.c.
1111 * Print error log if incoming connection configuration could
1112 not be found. Affected file silcd/server.c.
1114 * Fixed JOIN command to correctly save the founder mode
1115 to the client on normal SILC server, when the channel
1116 was created by the router. Affected file silcd/command.c.
1118 * Fixed LIST command (hopefully) to send correct reply
1119 packets. Affected file silcd/command.c.
1121 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * The silc_packet_receive_process now returns FALSE if the
1124 read data was invalid packet, and TRUE if it was ok.
1126 The server now checks that if unauthenticated connection
1127 sends data and its processing fails the server will close
1128 the connection since it could be a malicious flooder.
1130 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1132 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Make sure the warning about error opening a log file is
1135 printed only once and not everytime it fails (produces
1136 too much useless log). Affected file lib/silcutil/silclog.c.
1138 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1140 * Made the silc_server_daemonise() function more readable.
1141 Affected file silcd/server.c.
1143 * Pid file is now optional, the user may comment it out from
1144 the config file. Removed define SILC_SERVER_PID_FILE, we
1145 don't need a default any longer. Affected file
1146 configure.in.pre, lib/Makefile.am.pre.
1148 * Make some use of the pid file. The server now dies at startup
1149 if it detects a valid pid file on his path. The server would
1150 die anyway in this circumstance, because of the bind() failure.
1151 Affected file silcd/silcd.c.
1153 * No longer compiling lib/dotconf.
1155 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1157 * Fixed JOIN command parsing not to crash. Affected file
1158 lib/silcclient/command.c.
1160 * Fied the NICK_CHANGE notify to add the new client entry
1161 even it is resolved. This removes an <[unknown]> nick
1162 thingy bug in the client. Affected file is
1163 lib/silcclient/client_notify.c.
1165 * Do not try to allocate 0 bytes (efence does not like it)
1166 in lib/silccore/silccomand.c when encoding payload.
1168 * Do not take IRCNICK as nickname in Irssi SILC client since
1169 it is not possible to set nickname before hand connecting
1170 the server (TODO has an entry about adding auto-nicking
1173 * Changed the silc_server_command_pending to check whether
1174 there already exists an pending entry with the specified
1175 command, command identifier and pending callback. This is
1176 to fix IDENTIFY and WHOIS related crashes that may register
1177 multiple pending commands with same identifier. Affected
1178 file silcd/command.c.
1180 * Fixed the server to reconnect to the router even if it
1181 was already reconnecting and EOF was received. This to
1182 fix a possibility that the server wouldn't ever try to
1183 auto-reconnect to the router. Affected file silcd/server.c.
1185 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Fixed the server's password authentication to use the
1188 length of the locally saved password, and not the one
1189 sent in the packet. Affected file silcd/protocol.c.
1191 * Fixed same password authentication problem in the
1192 Authentication Payload handling routines in
1193 lib/silccore/silcauth.c.
1195 * Yet another password authentication problem fixed with
1196 channel password handling in silcd/command.c.
1198 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1200 * If first character of string in silc_parse_userfqdn is '@'
1201 then do not parse it. Affected file is
1202 lib/silcutil/silcutil.c.
1204 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Fixed minor bug in IDENTIFY command reply sending, which
1207 caused various weird problems during JOIN when it was
1208 resolving names for users. Affected file silcd/command.c.
1210 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Fixed the IDENTIFY command reply sending to chech better valid
1213 clients. It was possible to send incomplete list of replies.
1214 Affected file silcd/command.c.
1216 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Added silc_client_command[s]_[un]register functions now to
1219 dynamically register the commands in client library. Removed
1220 the static table of commands. This allows the client library
1221 to call commands without causing the application to know about
1222 what commands library has called.
1224 Removed the INFO command reply kludge to detect when the command
1225 was called by library. Now library use its own command reply
1226 function for INFO command.
1228 Added function silc_client_command_call to call a command.
1229 Application can use it to call command, not access the structure
1232 Now all commands that are sent by the client library (not
1233 explicitly sent by application) use own command reply functions.
1235 Affected files around lib/silcclient/ and in
1236 irssi/src/silc/core/.
1238 * Fixed the WHOIS command reply sending to chech better valid
1239 clients. It was possible to send incomplete list of replies.
1241 Fixed the WHOIS and IDENTIFY to send the request to router
1242 if normal server did not do it and did not find any results.
1244 Affected file silcd/command.c.
1246 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1248 * Moved the internal data from SilcClient context into its
1249 own file, not accesible to application. Affected files
1250 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1251 and other files in client library.
1253 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * Added doc/examples installation target in Makefile.am.pre.
1258 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1261 commands the found client entry will be removed from the
1262 cache, after notifying application about the error. Affected
1263 file lib/silcclient/command_reply.c.
1265 * Changed the /MSG to check for exact nickname user gave, and
1266 not let `nick' match `nick@host' if it is only one found. Now,
1267 user must type the exact nickname (like nick@host2) even if
1268 there are no more than one same nicks found. This is to avoid
1269 a possibility of sending nickname to wrong nickname since
1270 `nick' could match `nick@host'. Affected file is
1271 irssi/src/core/silc-servers.c.
1273 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1275 * Do not print "you are now server operator" or similar when
1276 giving /away command. Affected files are
1277 irssi/src/silc/core/client_ops.c, silc-servers.h.
1279 * Made the silc_server_command_pending_error_check to send
1280 the same command reply payload it received back to the
1281 original sender of the command. This way all arguments
1282 that was received by the server will be received by the
1283 client too. Affected file silcd/command.c.
1285 * Added the silc_idcache_add to return the created cache entry
1286 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1288 * Add global clients to expire if they are not on any channel.
1289 This is because normal server will never know if they signoff
1290 if they are not on any channel. The cache expiry will take
1291 case of these entries. This is done by normal servers only.
1292 The affected files are silcd/command_reply.c,
1293 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1295 * If server receives invalid ID notification for WHOIS or
1296 IDENTIFY and the ID exists in the lists, it is removed.
1297 Affected file silcd/command_reply.c.
1299 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1300 in client then client entry that it matches is searched and
1301 the nickname is printed on the screen for user. Affected
1302 file irssi/src/silc/core/client_ops.c.
1304 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1306 * Use cache entry expire time in the LIST command reply to
1307 purge old entries from the cache after the LIST command
1308 reply has been received. This way we don't have non-existent
1309 entries in the cache for too long. Affected file is
1310 silcd/command_reply.c.
1312 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1314 * If we are normal server, and we've not resolved client info
1315 in WHOIS or IDENTIFY from router, and it is global client,
1316 we'll check whether it is on some channel. If it is not
1317 then we cannot be sure about its validity and will resolve it
1318 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1319 file silcd/command.c.
1321 * Search channel by name (if possible) rather than by ID
1322 in IDENTIFY command's command reply. Affected file is
1323 silcd/command_reply.c.
1325 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1328 Updated specs and implemented it. Affected file silcd/command.c,
1329 silcd/packet_send.c and silcd/packet_receive.c.
1331 * Implemented the <founder auth> payload handling in the JOIN
1332 command. If provided all conditions for channel joining
1333 except requirement to provide correct passphrase can be
1334 overrided by the channel founder. Updated the protocol specs.
1335 Affected file silcd/command.c.
1337 Added support for founder auth in JOIN command in client
1338 library. Fixed the parsing of the JOIN command now to support
1339 all options as they should be. The affected file is
1340 lib/silcclient/command.c.
1342 * Optimized the WHOIS and IDENTIFY commands to send the request
1343 to router only if it includes nicknames or other names. If
1344 they include only IDs then check the local cache first before
1345 routing. Affected file is silcd/command.c.
1347 * Added channels topic announcements. Affected file is
1348 silcd/packet_receive.c and silcd/server.c.
1350 * Fixed the silc_server_send_notify_topic_set to really destine
1351 the packet to channel. Affected file silcd/packet_send.c.
1353 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1354 library. Affected file lib/silcclient/client_notify.c.
1356 * Added UMODE announcements. Affected file silcd/server.c.
1358 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1360 * Memory leak fixes in:
1362 lib/silcutil/silcsockconn.c
1363 lib/silcske/silcske.c
1364 lib/silcske/groups.c
1366 lib/silccrypt/silcpkcs.c
1367 lib/silccore/silccommand.c
1368 lib/silccore/silcidcache.c
1373 * ROBOdoc documented the lib/silcske/groups.h file and a
1374 bit changed the interface for better.
1376 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1378 * Update the client entry context in the ID cache after
1379 nick change. Affected file lib/silcclient/command.c.
1380 Fixes the CUMODE command when regaining founder privileges,
1381 and a little WHOIS problem.
1383 * Fixed silc_net_gethostbyname to correctly call the
1384 inet_ntop. Affected file lib/silcutil/silcnet.c.
1386 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1388 * Added IPv6 support checking to the configure.in.pre, added
1389 also --enable-ipv6 option to override the check. Affected
1390 file configure.in.pre.
1392 * The silc_thread_create now calls the start function
1393 directly if threads support is not compiled in. Removes
1394 ugly #ifdef's from generic code. Affected files are
1395 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1397 * Added silc_net_gethostby[name/addr]_async to asynchronously
1398 resolve. Affected files are lib/silcutil/silcnet.[ch].
1400 * Added support for rendering IPv6 based server, client and
1401 channel IDs. Affected file lib/silcutil/silcutil.c.
1403 * Added support for creating IPv6 based server IDs. Affected
1404 file is silcd/serverid.c.
1406 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1408 * Added silc_net_gethostby[addr/name] into the
1409 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1410 routines. Added silc_net_is_ip[4/6]. Affected file is
1411 lib/silcutil/unix/silcunixnet.c. All routines that take
1412 address as argument now supports both IPv4 and IPv6 addresses.
1414 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1416 * Fixed LIST command reply sending in server. Affected file
1419 * Server now sends the kicker's client ID in the KICK notify
1420 to the kicked client. Affected file silcd/command.c.
1422 * The client library now parses the kickers client ID and
1423 UI displays it. Affected files lib/silcclient/client_notify.c
1424 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1426 * Made all payload parsing function prototypes consistent.
1427 They all take now const unsigned char * and uint32 pair as
1428 the payload data instead of SilcBuffer. Changes all around
1429 the source tree. Other unsigned char* -> const unsigned char*
1430 changes around the tree as well.
1432 * Optimized SFTP client and server packet sending not to
1433 allocate new buffer for each packet but to recycle the
1434 first allocated buffer. Affected files are
1435 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1437 * Optimized the SFTP client to use SilcList instead of
1438 SilcDList for requests, because it is faster. Affected file
1439 is lib/silcsftp/sftp_client.c.
1441 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1442 into lib/silccore/silcid.[ch].
1444 Renamed silcpayload.[ch] into silcargument.[ch].
1446 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * If client entry is deleted with active key agreement
1449 session, abort the session.
1451 The silc_client_abort_key_agreement now calls the completion
1452 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1454 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1457 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Don't use __restrict in older GCC's. Affected file is
1460 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1462 * silc_net_localhost now attempts to reverse lookup the
1463 IP/hostname. Affected file lib/silcutil/silcnet.c.
1465 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1466 command. It can be used to gain founder privileges at
1467 the same time when joining the channel.
1469 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1470 kicker's client ID as well. Updated protocol specs.
1472 Defined that the server must send SILC_COMMAND_IDENTIFY
1473 command reply with error status to client who sent
1474 private message with invalid client ID.
1476 Updated the protocol specification.
1478 * Added silc_server_send_command_reply to send any
1479 command reply. Affected file silcd/packet_send.[ch].
1481 * Added silc_id_payload_encode_data to encode ID payload
1482 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1484 * The server now send IDENTIFY command reply with error
1485 status if client ID in private message is invalid. Affected
1486 file silcd/packet_receive.c.
1488 * Save the server key file with server's IP address in
1489 the filename instead of hostname. The affected file is
1490 irssi/src/silc/core/client_ops.c.
1492 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1497 * Added libtool support for compiling shared objects in
1498 lib/silcsim. Affected file configure.in.pre and
1499 lib/silcsim/Makefile.am. Original patch by cras.
1501 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1503 * Pid file configuration, and server's config file fixes
1504 patch by toma. Updated CREDITS file.
1506 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Fixed silc_client_channel_message to not try to decrypt
1509 the message twice if it resolved the destination client
1510 information. This could cause of dropping one channel
1511 message. Affected file lib/silcclient/client_channel.c.
1513 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1516 lib/silcclient/client.c. This function is used when the SILC
1517 Client is run under some other scheduler, or event loop or
1518 main loop. On GUI applications, for example this may be
1519 desired to used to run the client under the GUI application's
1520 main loop. Typically the GUI application would register an
1521 idle task that calls this function multiple times in a second
1522 to quickly process the SILC specific data.
1524 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1526 * Fixed silc_server_drop() for dropping the supplementary
1527 groups as well, this could cause a security hole on some
1530 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1535 * Write PID file after dropping privileges. Added -F option
1536 to run server on foreground. A patch by debolaz.
1537 Affected files silcd/server.c, silcd/silcd.c.
1539 * Fixed MOTD to return the MOTD file server name. Affected
1540 file silcd/command.c.
1542 * Added INFO command reply handling to the Irssi SILC Client.
1543 Affected file irssi/src/silc/core/client_ops.c.
1545 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Fixed the silc_idcache_list_* routines to really support
1548 the dynamic list. Fixes a crash. Affected file is
1549 lib/silccore/silcidcache.c.
1551 * Fixed the LIST command reply to really call LIST command's
1552 pending callbacks. Affected file silcd/command_reply.c.
1554 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Update conn->local_entry->nickname after giving NICK
1557 command. Affected file lib/silcclient/command.c.
1559 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1561 * Added the [pid] option to the silcd configuration file
1563 Affected files: serverconfig.[ch] and silcd.c
1565 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Save fingerprint in WHOIS command reply in server.
1568 Affected file silcd/command_reply.c.
1570 * Fixed NICK commands pending callback registration.
1571 Affected file lib/silcclient/command.c.
1573 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1575 * Use ++server->cmd_ident when sending commands in server,
1576 instead of random number. Affected file silcd/command.c.
1578 * Fixed GETKEY command reply to call actually GETKEY pending
1579 command callbacks. Affected file silcd/command_reply.c.
1581 * A bit stricter check for nicknames. Check for same nickname
1582 in NICK command also. Affected file silcd/command.c.
1584 * Do not call INFO command everytime client ID changes, only
1585 during first connecting. Affected file lib/silcclient/client.c.
1587 * Set the new nickname only after successful command reply for
1588 NICK command is returned by server. Affected file
1589 lib/silcclient/command.c.
1591 * Remove nicknames from nicklist during server_signoff notify.
1592 Should fix /NAMES bit more. The affected file is
1593 irssi/src/silc/core/silc-channels.c.
1595 * Added `fingerprint' field to the SilcIDListData in the
1596 silcd/idlist.h to hold the fingerprint of the client's
1599 Send the fingerprint of the client's public key in WHOIS
1602 Affected files silcd/command.c, and silcd/idlist.[ch].
1604 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1605 create fingerprint from given data.
1607 * Show the fingerprint of the client's public key in WHOIS.
1608 Affected files irssi/src/module-formats.[ch] and
1609 irssi/src/silc/core/client_ops.c.
1611 * Format the multiple same nicknames also during JOIN and
1612 NICK_CHANGE notifys. Affected file is
1613 lib/silcclient/client_notify.c.
1615 * Do not print error on screen for invalid private message
1616 payload since it can come if someone is sending private
1617 messages with wrong key. Affected file
1618 lib/silccore/silcprivate.c.
1620 * Fixed multiple concurrent /PING crash. Affected file
1621 lib/silcclient/command.c.
1623 * Changed the wrong ID encoding. All IP addresses must be
1624 in MSB first order in encoded format. They were encoded
1625 wrong and was in LSB format. Affected files are
1626 silcd/serverid.c, lib/silcutil/silcutil.c.
1628 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1630 * Call the `connect' client operation through the scheduler
1631 in case of error. Affected file lib/silcclient/client.c.
1633 * Call the `failure' client operation even if the error
1634 occurred locally during a protocol. Affected file is
1635 lib/silcclient/protocol.c.
1637 * Added support of sending LIST command to router from normal
1638 server. This way normal server can get list of all channels
1639 in the network too. Fixed the channel list sending in the
1640 server too. Affected files are silcd/command.c, and
1641 silcd/command_reply.[ch].
1643 * Added silc_server_update_channels_by_server and
1644 silc_server_remove_channels_by_server. They are used during
1645 disconnection of primary router and in backup router protocol.
1646 Affected file silcd/server_util.[ch], silcd/server.c and
1647 silcd/server_backup.c.
1649 * Fixed channel adding to global list in IDENTIFY command
1650 reply in server. Affected file silcd/command_reply.c.
1652 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * If the incoming packet type is REKEY or REKEY_DONE process
1655 that packet always synchronously. Fixes yet another MAC
1656 failed error on slow (dialup) connections. Affected file
1657 lib/silcclient/client.c and silcd/server.c.
1659 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * Call check_version SKE callback for initiator too. Affected
1662 file lib/silcske/silcske.c.
1664 * Implemented fix for security hole found in the SKE that was
1665 fixed in the specification few days back; the initiator's
1666 public key is now added to the HASH value computation.
1667 Added backwards support for the old way of doing it too, for
1668 old clients and old servers. Affected file is
1669 lib/silcske/silcske.c.
1671 * Enabled mutual authentication by default in SKE. If initiator
1672 is not providing mutual authentication the responder will
1673 force it. This will provide the proof of posession of the
1674 private key for responder. The affected files are
1675 lib/silcclient/protocol.c and silcd/protocol.c.
1677 * Do not cache anymore the server's public key during SKE.
1678 We do mutual authentication so the proof of posession of
1679 private key is done, and if the server is authenticated in
1680 conn auth protocol with public key we must have the public
1681 key already. Affected file silcd/protocol.c.
1683 * Added new global debug variable: silc_debug_hexdump. If
1684 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1685 file lib/silcutil/silclog.[ch].
1687 * Fixed compilation warning due to char * -> const char *.
1688 Affected files lib/silcutil/silcnet.h, and
1689 lib/silccore/silcauth.[ch].
1691 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Fixed CMODE command when new channel key was created. If
1694 the creation failed the old key was removed. Next time giving
1695 same command would crash the server since the old key was
1696 freed already. Affected file silcd/command.c.
1698 * Fixed the silc_server_announce_get_channels to not crash
1699 on reconnect. Affected file silcd/server.c.
1701 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1703 * Added silc_log_set_debug_string function to set a regex
1704 string to match for debug output. Only the function names,
1705 or filenames matching the given debug string is actually
1706 printed. This way it is possible to filter out those debug
1707 strings that user is not interested in.
1709 Fixed a bug in silc_string_regexify.
1711 Affected files lib/silcutil/silclog.[ch], and
1712 lib/silcutil/unix/silcunixutil.c.
1714 * Changed the -d options in both server and Irssi SILC client
1715 to take the debug string as argument. Affected files
1716 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1718 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * Added silc_hash_babbleprint to create a Bubble Babble
1721 Encoded fingerprint. The encoding is developed by Antti
1722 Huima (draft-huima-babble-01.txt), and it creates human
1723 readable strings out of binary data. Affected file
1724 lib/silccrypt/silchash.[ch].
1726 * Print the babble print now in addition of fingerprint as well
1727 in Irssi SILC client. Affected files are
1728 irssi/src/fe-common/silc/module-formats.[ch],
1729 irssi/src/fe-common/silc/core/client_ops.c.
1731 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Fixed a security problem found in SKE. The initiator's
1734 public key too is now added to the HASH hash value creation
1735 which is signed by the responder to create the SIGN value.
1736 This will prevent anyone in the middle to lie to the responder
1737 about the initiator's public key. If this is done now, the
1738 man in the middle will get caught. Updated the protocol
1741 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Better installation directory handling. Configure module
1744 paths and other paths automatically to example_silc* files
1745 in doc/. A patch by toma.
1747 * Fixed compiler warning from MPI library, and from SILC RNG.
1750 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1751 It can be configured with ./configure. A patch by toma.
1753 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Find correct make to use in prepare-clean. A patch by
1756 toma. Affected file prepare-clean.
1758 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1760 * Added irssi variables use_auto_addr, auto_bind_ip,
1761 auto_bind_port and auto_public_ip.
1763 * Changed the interface for silc_client_send_key_agreement
1764 in lib/silcclient/silcapi.h
1768 irssi/src/silc/core/silc-core.c
1770 lib/silcclient/silcapi.h
1771 irssi/src/silc/core/silc-channels.c
1772 lib/silcclient/client_keyagr.c
1775 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Added silc_pkcs_public_key_compare to compare two
1778 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1780 * Check that the client who set the founder mode on the
1781 channel is the same client that is giving the founder
1782 mode to itself. It is done by comparing the saved public
1783 key (it is saved even in the authentication is passphrase).
1784 Affected file silcd/command.c.
1786 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Do not process packet for disconnected socket connection.
1789 Affected file lib/silccore/silcpacket.c.
1791 * Process the DISCONNECT packet through scheduler in the
1792 client library. Affected file lib/silcclient/client.c.
1794 * Fixed the silc_client_packet_parse to not to increase
1795 the packet sequence number if the conn->sock and the
1796 current socket connection is not same. This can happen
1797 for example during key agreement when the conn includes
1798 multiple socket connections (listeners). Affected file
1799 lib/silcclient/client.c.
1801 * The sender of the file transfer request now provides also
1802 the pointer (listener) for the key exchange protocol. If
1803 the listener cannot be created then it sends empty key
1804 agreement and lets the receiver provide the listener.
1806 Added `local_ip' and `local_port' arguments to the
1807 silc_client_file_send. If they are provided they are used,
1808 if not then it will attempt to find local IP address, if
1809 not found or bind fails then the remote client will provide
1812 Affected files are lib/silcclient/client_ftp.c and
1813 lib/silcclient/silcapi.h.
1815 * Extended the FILE SEND command to support defining the
1816 local IP and port for key exchange listener. They are
1817 optional. Affected file irssi/src/silc/core/silc-servers.c.
1819 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * Defined to WHOIS command reply the sending of fingerprint
1822 of the client's public key (if the proof of posession of the
1823 corresponding private key is verified by the server).
1824 Updated to the protocol specification.
1826 * Added support of receiving the client's public key's
1827 fingerprint in command reply in client library. Affected
1828 file is lib/silcclient/command_reply.c, and
1829 lib/silcclient/idlist.[ch].
1831 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * Do not send over 128 chars long nickname to the server
1834 in NICK command. Affected file lib/silcclient/command.c.
1836 * Do not send over 256 chars long channel names to the server
1837 in JOIN command. Affected file lib/silcclient/command.c.
1839 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1841 * Assure that silc_server_close_connection cannot be called
1842 twice for same socket context. Affected file is
1845 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Send error message to application if opening file for
1848 writing during file transfer fails. Affected file is
1849 lib/silcclient/client_ftp.c.
1851 Remove all file transfer sessions for a client that we're
1852 removing from ID cache.
1854 Affected file is lib/silcclient/client_ftp.c.
1856 * Fixed silc_net_addr2bin to return correct address. Affected
1857 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1859 * Fixed file transfer session removing on signoff notify.
1860 Affected file irssi/src/silc/core/silc-servers.c.
1862 * Added the SilcClientFileError to be returned in the monitor
1863 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1864 Affected file lib/silcclient/silcapi.h.
1866 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * Fixed a crash in silc_client_ftp_free_sessions and
1869 silc_client_ftp_session_free_client. Affected file
1870 lib/silcclient/client_ftp.c.
1872 * Added `disabled' field in the SilcChannelEntry in the server
1873 to indicate if the server entry is disabled. Affected file
1874 silcd/idlist.h, silcd/command[_reply].c.
1876 * SILC server adds now /var/run/silcd.pid everytime it is
1877 started. Affected file silcd/silcd.c.
1879 * Added silc_server_packet_send_clients to send a packet to
1880 the provided table of client entries. Affected file

1883 * Fixed a crash in client resolving in client_prvmsg.c in
1884 client library. Affected file lib/silcclient/client_prvmsg.c.
1886 * Do not actually remove the client directly from ID cache
1887 during SERVER_SIGNOFF, but invalidate it. This way we
1888 preserve the WHOWAS info for the client. Affected file
1889 silcd/server_util.c.
1891 * Fixed SERVER_SIGNOFF notify handling in the server. The
1892 server is now able to process incoming SERVER_SIGNOFF notify
1893 for a server that it doesn't even know about. It will remove
1894 the clients provided in the notify. Affected file
1895 silcd/packet_receive.c.
1897 * Check for partial packet in data queue after every packet that
1898 was found from the queue. Return and wait for more data if
1899 there is partial data in queue. Affected file is
1900 lib/silccore/silcpacket.c.
1902 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Added SilcClietFileError enum to indicate error in
1905 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1906 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1907 Affected files lib/silcclient/silcapi.h and
1908 lib/silcclient/client_ftp.c.
1910 * Check that newsize in silc_buffer_realloc is larger than
1911 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1913 * Added better monitor of file transfers. It now monitors
1914 key agreement protocol during the file transfer too. Added
1915 error reporting too. Affected files
1916 irssi/src/silc/core/silc-servers.c,
1917 irssi/src/fe-common/silc/module-formats.[ch].
1919 * Wrote a help file for FILE command.
1921 * Added silc_rng_global_get_byte_fast to get not-so-secure
1922 random data as fast as possible. Random data is read from
1923 /dev/urandom if available and from the SILC RNG if not
1924 available. It is used in padding generation. Affected file
1925 lib/silccrypt/silcrng.[ch].
1927 * All packets in client library are now processed synchronously.
1928 Optimized packet processing a lot. Affected file
1929 lib/silcclient/client.c.
1931 * All server connection packets are processing synchronously
1932 now in server, to optimize packet processing. Affected file
1935 * Include files are installed now only in Toolkit distribution
1936 if make install is given. Affected files: all Makefile.am's.
1938 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Assure that silc_client_notify_by_server_resolve does not
1941 resolve the client information multiple times. If it cannot
1942 be found by the first it cannot be found at all. Affected
1943 file lib/silcclient/client_notify.c.
1945 * Fixed WHOWAS command reply calling. Affected file
1946 lib/silcclient/command_reply.c.
1948 * Removed all references to silc_idlist_get_client from the
1949 Irssi SILC client since that call is internal call used by
1950 the library. The Irssi SILC client will use now client
1951 retrieval functions found in silcapi.h.
1953 * Fixed a bug in resolving nickname info before sending
1954 private message. It used freed memory. Affected file
1955 irssi/src/silc/core/silc-servers.c.
1957 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Assure my_channels statistics cannot go negative in server.
1960 Affected files silcd/server.c, silcd/server_util.c.
1962 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1966 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1972 lib/sftp/sftp_fs_memory.c.
1974 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * Added silc_net_localip to return local host's IP address.
1977 Affected file lib/silcutil/silcnet.[ch].
1979 * If key exchange or rekey protocol is active for a connection
1980 parse all packets syncronously since there might be packets
1981 in packet queue that we are not able to process without first
1982 processing packets before them. Affected file silcd/server,
1983 lib/silcclient/client.c.
1985 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1986 whether library should continue processing the packet.
1987 Affected file lib/silccore/silcpacket.h.
1989 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1990 SilcSFTPMonitorData to SFTP server to monitor various
1991 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1992 lib/silcsftp/sftp_server.c.
1994 * Added silc_file_size to return file size. Affected file
1995 lib/silcutil/silcutil.[ch].

1998 Added preliminary support for simple client to client one-file
1999 transmission. Affected file lib/silcclient/client_ftp.c,
2000 lib/silccilent/client.[ch].
2002 * Added new local command FILE to the Irssi SILC Client.
2003 It is used to perform the file transfer. It has subcommands
2004 SEND, RECEIVE, SHOW and CLOSE. Affected files
2005 irssi/src/silc/core/client_ops.c,
2006 irssi/src/silc/core/silc-server.[ch].

2018 lib/silcutil/silcutil.[ch].
2020 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Resolve the client info when received private message or
2023 channel message for a client which nickname we don't know.
2024 Affected files lib/silcclient/client_prvmsg.c and
2025 lib/silcclient/client_channel.c.
2027 * Do not crash in /KEY if client is not connected. Affected
2028 file irssi/src/silc/core/silc-channels.c.
2030 * Added SilcClientStatus field to the SilcClientEntry in the
2031 lib/silcclient/idlist.h.
2033 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2034 is incomplete and is being resolved, it won't be resolved
2037 Make sure also that USERS command reply does not resolve
2038 twice information. Affected file is
2039 lib/silcclient/command_reply.c.
2041 Make sure that silc_client_get_clients_by_list does not
2042 resolve twice same information.
2044 * Check for valid client->id in the silc_server_free_client_data.
2045 Affected file silcd/server.c.
2047 * Fixed /GETKEY nick@server not to crash if the server entry
2048 is not found. Affected file lib/silcclient/command.c.
2050 * Fixed the silc_server_check_cmode_rights to check the
2051 requested modes correctly. Affected file silcd/command.c.
2053 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * Better checks for non-printable chars in nick added.
2056 Affected file silcd/command.c.
2058 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Call the silc_server_udpate_servers_by_server in the
2061 primary router that comes back online in the backup resuming
2062 protocol. Otherwise it routes packets wrong. Affected file
2063 silcd/server_util.[ch], silcd/server_backup.c.
2065 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2068 lib/silcutil/silcbuffmt.[ch].
2070 * Redefined the SILC packet header to include the padding
2071 length. Affected file lib/silccore/silcpacket.[ch].
2073 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2074 length for maximum padding up to 128 bytes). Affected
2075 file lib/silccore/silcpacket.h.
2077 * Removed all backwards support for old 0.5.x MAC thingies.
2078 The SILC packet header change makes it impossible to be
2079 backwards compatible.
2081 * Send the ENDING packet with timeout in the backup resuming
2082 protocol. This is to assure that all routers has connected
2083 to the primary router. Affected file silcd/server_backup.c.
2085 * Changed the RNG to take the first IV from random data. It
2086 used to take it from zero actually. Changed the RNG also
2087 to use /dev/urandom during session. /dev/random is used
2088 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2090 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2092 * Changed the SILC packet header to have the first two bytes
2093 (the packet length) encrypted. Affected files aroung the
2094 code tree, lib/silccore/silcpacket.[ch]. Removed the
2095 SilcPacketCheckDecrypt callback. It is not needed anymore
2096 since the silc_packet_receive_process will determine now
2097 whether the packet is normal or special.
2099 * Implemented the unidirectional MAC keys. Affected files
2100 lib/silcske/silcske.c, silcd/protocol.c and
2101 lib/silcclient/protocol.c.
2103 * Implemented the packet sequence number to the MAC computation.
2104 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2105 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2106 lib/silcclient/protocol.c.
2108 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Allow backup router to announce servers. All servers
2111 announced by backup router are added to the global list
2112 automatically. Update hte server's socket to our primary
2113 router also when backup router announces a server.
2114 Affected file silcd/packet_receive.c.
2116 * Do not update the client->router in the function
2117 silc_server_udpate_clients_by_server if the client is on
2118 global list. We might fail to find any specific server
2119 for locally connected clients and local cell clients. They
2120 should still use the `from' and not `to' as client->router.
2121 This fixes backup router resuming protocol. Affected file
2122 silcd/server_util.c.
2124 * Decrease channel statistics count only if the channel
2125 deletion worked. Affected files are silcd/server.c and
2126 silcd/server_util.c.
2128 * Added silc_server_update_servers_by_server to update origin
2129 of all server entries. Used during backup router protocol.
2130 Affected files silcd/server_util.[ch], silcd/server.c. and
2131 silcd/backup_router.c.
2133 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2134 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2135 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2136 lib/silccrypt/silchmac.c.
2138 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Assure that router cannot reroute the same channel message
2141 to the sender. Affected file silcd/packet_receive.c.
2143 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Made better checks that the channel message is not sent
2146 to the router it came from. Affected file is
2147 silcd/packet_send.c. Fixed memory leak too.
2149 * Announce informations for incoming router connection, but
2150 only after checking if it is replaced by backup router.
2151 Affected file silcd/packet_receive.c.
2153 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Fixed the backup resuming protocol to work in multiple
2156 router environment. Affected file silcd/server_backup.c.
2158 * Route packet only to one router in the function
2159 silc_server_packet_send_to_channel. Affected file is
2160 silcd/packet_send.c.
2162 * Fixed silc_server_send_notify_dest to set the broadcast
2163 flag. Fixed the silc_server_send_notify_topic to actually
2164 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2165 Affected file silcd/packet_send.c.
2167 * Changed the SFTP Filesystem interface. Changed the
2168 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2169 the filesystem operation function. The SilcSFTPFilesystem
2170 is now a context that is allocated by all filesystem allocation
2171 functions and it already includes the operations structure
2172 and filesystem specific context. It is given as argument
2173 now to the silc_sftp_server_start. This made the interface
2174 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2175 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2177 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Changed the backup router adding and getting interfaces
2180 in the server. The router that will be replaced by the
2181 specified backup router is now sent as argument. Affected
2182 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2185 * Added silc_net_addr2bin_ne to return the binary form of
2186 the IP address in network byte order. Affected files
2187 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2189 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * Check for existing server ID in silc_server_new_server
2192 and in silc_server_connect_to_router_final and remove the
2193 old entry if it exists. Affected file silcd/packet_receive.c,
2196 * Send the channel message always to only one router, either
2197 in upstream or downstream. Affected file is
2198 silcd/packet_send.c.
2200 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2202 * Wrote the definition of the backup resuming protocol to the
2203 protocol specification.
2205 * Removed one redundant channel key generation from normal
2206 server during joining procedure. Removed one redundant
2207 channel key sending from server to router during joining
2208 procedure. Affected file silcd/command.c.
2210 * Made minor bugfixes to the backup router resuming protocol.
2211 Affected file silcd/server_backup.c, server.c.
2213 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Added --disable-asm configuration option. Affected files
2216 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2219 * Implemented the backup resuming protocol that is used to
2220 resume the primary router position in the cell after the
2221 primary router comes back online. Affected files
2222 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2223 and silcd/server_util.[ch].
2225 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Sleep two (2) seconds after sending QUIT command to server.
2228 Affected file lib/silcclient/command.c.
2230 * Assure that if outgoing data buffer is pending do not force
2231 send any data. Affected file silcd/packet_send.c.
2233 * Assure that if outgoing data buffer is pending do not force
2234 send any data. Affected file lib/silcclient/client.c.
2236 * Implemented the backup router support when the primary router
2237 goes down. The servers and routers can now use the backup
2238 router as new primary router without loosing connectivity.
2240 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2243 in the server to indicate disabled entry. All data read
2244 from the connection will be ignored and no data is sent
2245 for entry that is disabled. Affected files are
2246 silcd/idlist.h, silcd/server.c.
2248 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Created SFTP client and server test programs in the
2251 lib/silcsftp/tests directory.
2253 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * Implemented memory filesystem (virtual filesystem) for
2256 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2259 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2261 * Implemented the SFTP (SSH File Transfer Protocol) to the
2262 lib/silcsftp. It includes SFTP client and SFTP server
2265 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Moved lib/silccore/silcprotocol.[ch] to the
2268 lib/silcutil library.
2270 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2271 take variable argument list pointer as argument. Affected
2272 file lib/silcutil/silcbuffmt.[ch].
2274 * Added silc_buffer_set function that is used to set data
2275 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2276 Affected file lib/silcutil/silcbuffer.h.
2278 * Changed various routines in the core library to use the new
2279 silc_buffer_set instead of allocating new buffer only for
2282 * Added 64-bit value formatting and unformatting support to the
2283 silc_buffer_[un]format routines. Affected file is
2284 lib/silcutil/silcbuffmt.[ch].
2286 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2287 to includes/bitmove.h.
2289 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Fixed channel user mode saving in client library. Affected
2292 file lib/silcclient/command[_reply].c.
2294 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * Defined the file transfer to the SILC Protocol. Added
2297 new packet type SILC_PACKET_FTP and defined File Transfer
2298 Payload. The mandatory file transfer protocol is SFTP
2299 (SSH File Transfer Protocol). Affected file in addition
2300 of the internet draft is lib/silccore/silcpacket.h.
2302 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2303 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2304 is used as part of backup router protocol when the primary
2305 router of the cell is back online and wishes to resume
2306 the position as primary router.
2308 * Redefined the MAC generation keys in the protocol. The
2309 same key is not used anymore in both direction. Both
2310 direction will now use different keys for sending and
2311 receiving. This fixes a potential security flaw. This
2312 change causes incompatibilities in the protocol.
2314 * Redefined also the MAC computation from the packet.
2315 An packet sequence number is now added to the MAC
2316 computation. This prevents possible replay attacks against
2317 the protocol. This change too causes incompatibilities
2320 Added `sequence' field to the SilcPacketContext to hold
2321 the current sequence number for the packet.
2323 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Added `created' field to the SilcIDListData in the file
2326 silcd/idlist.h to indicate the time when the entry was
2329 * Added `created' field to the SilcChannelEntry too. Affected
2330 file silcd/idlist.h.
2332 * Added `creation_time' aguments to all the announcement functions
2333 in the server. If it is provided then only the entries that
2334 was created after the provided time frame are actually
2335 announced. Affected file silcd/server.[ch].
2337 * The protocol says that the Channel ID's IP address must be
2338 based on the router's IP address. Added check for this in
2339 the silc_server_new_channel when processing incoming New Channel
2340 Payload. Affected file silcd/packet_receive.c.
2342 * Print out the correct version with --version in SILC client.
2343 Affected file irssi/src/silc/core/silc-core.c.
2345 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Fixed WHOWAS command to check for completnes of the client
2348 entry always, not just when the command is coming from client.
2349 Affected file silcd/command.c.
2351 * Added new function silc_server_packet_queue_purge to purge the
2352 outgoing data queue to the network. After the function returns
2353 it is guaranteed that the outgoing packet queue is empty.
2354 Affected file silcd/packet_send.[ch].
2356 * Purge the outgoing packet queue in the rekey protocol's final
2357 callback to assure that all rekey packets go to the network
2358 before quitting the protocol. Affected file silcd/server.c.
2360 * Added silc_client_packet_queue_parse as similar function as
2361 in server to the client library. The affected file is
2362 lib/silcclient/client.c.
2364 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Splitted silcd/server.c and created silcd/server_util.[ch]
2367 for utility functions.
2369 * Added new socket flag SILC_SF_DISABLED to indicate that the
2370 connection is open but nothing can be sent to or received from
2371 the connection. Affected file lib/silcutil/silsockconn.[ch].
2372 The checking for disabled socket is checked in the low level
2373 silc_socket_write and silc_socket_read functions.
2375 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Allow only nicknames and channel names that fits into the
2378 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2380 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * When processing JOIN command reply in server check that if
2383 the channel exists in our global list we'll move it the local
2384 list. Affected file silcd/command_reply.c.
2386 * Fixed the check whether client is joined on the channel already
2387 in JOIN command. Affected file lib/silcclient/command.c.
2389 * Fixed the JOIN command reply to check whether the channel
2390 already exists. Affected file lib/silcclient/command_reply.c.
2392 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Added silc_ske_status_string to map the SKE error numbers
2395 to readable strings. The affected files are
2396 lib/silcske/silcske[_status].[ch].
2398 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2400 * Do not show the private channels on the WHOIS channel list
2401 as it is not allowed by the protocol. The affected file is
2404 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Assure that the packet length digged from the actual packet
2407 is something sensible in the silc_packet_decrypt_rest_special
2408 in lib/silccrypt/silcpacket.c.
2410 * Free and NULL the allocated pointer in silc_hmac_alloc if
2411 the HMAC allocation fails. The affected file is
2412 lib/silccrypt/silchmac.c.
2414 * Print the selected security properties to the log files in
2415 the server. Affected file silcd/protocol.c.
2417 * Add SKE's reference counter even if calling the completion
2418 callback manually. Otherwise it goes negative, although it
2419 does not cause any problems. The affected file is
2420 lib/silcske/silcske.c.
2422 * Remove the client entry with short timeout after giving the
2423 KILL command. Affected file lib/silcclient/command.c.
2425 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2426 case all found clients are already disconnected (WHOWAS would
2427 found them) in the server. Affected file silcd/command.c.
2429 * Update the last_receive (time of last data received) to be
2430 updated only when received private or channel message so that
2431 the idle time showed in WHOIS makes more sense.
2433 * Added boolean field `valid' in to the SilcClientEntry in the
2434 client library to indicate whether the entry is valid or not.
2435 This fixes the nickname change bug on channel when changing
2436 the nickname to be same than the old (like nick to Nick) the
2437 nickname formatter doesn't set the new nick anymore to Nick@host.
2438 Affected file lib/silcclient/idlist.[ch].
2440 * Now actually fixed the nickname changing on disconnection.
2441 Added new function silc_change_nick to the Irssi SILC Client.
2442 Affected file irssi/src/silc/core/client_ops.c,
2443 irssi/src/silc/core/silc-nicklist.[ch].
2445 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * Check that the public key exists in the GETKEY command before
2448 trying to encode it. Affected file silcd/command.c.
2450 * Print some notifications on received public keys with GETKEY
2451 command in the Irssi SILC Client. Affected files are
2452 irssi/src/fe-common/silc/module-formats.[ch],
2453 irssi/src/silc/core/client_ops.c.
2455 * Use IDENTIFY command to resolve the server information in the
2456 GETKEY command instead of INFO command. Affected file
2457 lib/silcclient/command.c.
2459 * All command reply functions in the client library now calls
2460 the pending command reply callbacks even if an error has
2461 occurred. The server has done this a long time and now it was
2462 time to move the client library to this as well. Now all
2463 errors can be delivered back to the pending command reply
2464 callbacks if necessary. Affected files are
2465 lib/silcclient/command[_reply].[ch].
2467 * Change the nickname on disconnection back to the username
2468 because in reconnect the server will enforce it to it anyway.
2469 Affected file irssi/src/silc/core/silc-servers.c.
2471 * Fixed a config file parsing bug in the Irssi SILC client.
2472 Affected file irssi/src/silc/core/clientconfig.c.
2474 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * When printing the channel mode on JOIN, verify that the
2477 channel key and channel's HMAC are valid. Affected file
2478 irssi/src/silc/core/client_ops.c.
2480 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2483 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2484 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2486 * Removed channel key rekey task deleting from the function
2487 silc_server_save_channel_key. Affected file silcd/server.c.
2488 Added explicit timeout task context instead that is used to
2489 delete the task if we are registering a new task before the
2490 new task has elapsed.
2492 * When channel key rekey occurs the client library now saves
2493 the old channel key for a short period of time (10 seconds) and
2494 is able to use it in case some is still sending channel
2495 messages encrypted with the old key after the rekey. Affected
2496 file lib/silcclient/[idlist.h|client_channel.c].
2498 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Added check to the silc_server_new_id_real to not accept
2501 new ID if it is the sender's own ID. Affected file is
2502 silcd/packet_receive.c.
2504 * Assure that we do not announce ourself or the one we've
2505 sending our announcements when we're router and are announcing
2506 servers to our primary router. Affected file silcd/server.c.
2508 * Fixed silc_server_command_identify_check_client to assemble
2509 correct WHOIS packet. It send corrupted WHOIS packet and
2510 caused problem with router to router connections. Affected
2511 file silcd/command.c.
2513 Fixed also silc_server_command_whois_check the same way
2514 as for the IDENTIFY command.
2516 * Added new SilcIDListStatus to the server in the SilcIDListData
2517 structure. The status now includes the current status of
2518 the entry (like registered, resolved etc.). Affected file
2519 silcd/idlist.[ch]. Defined a bunch of different status types
2520 as well. This replaced the old boolean registered field as well.
2522 Added resolve_cmd_ident field to the SilcClientEntry structure
2523 too so that if the entry is for example being resolved so
2524 another command may attach to the same pending command reply
2525 without requiring to resolve the same entry again. This concept
2526 should optimize the WHOIS and the IDENTIFY resolving under
2527 heavy load by taking away unnecessary resolving for entries
2528 that are being resolved already.
2530 Added support for adding multiple pending commands for one
2531 command idenfier. Affected file silcd/command[_reply].[ch].
2533 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2534 before deleting the data. Otherwise the hash table will have
2535 freed data in comparison functions. Affected file is
2536 silcd/command_reply.c.
2538 * Fixed silc_idlist_replace_client_id to add the new entry to
2539 the cache with NULL nickname. Otherwise there will be invalid
2540 memory as the nickname after the nickname is freed. Affected
2541 file silcd/packet_receive.c.
2543 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2544 saved into wrong slots because the previous number of entries
2545 was not taken into account. Affected file silcd/idlist.c.
2546 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2548 * If we are router and we receive JOIN notify to a channel that
2549 does not have any users then notified client is marked as the
2550 channel founder, as it is it. The affected file is
2551 silcd/packet_receive.c
2553 * Added to the extended hash table API's table_del_*ext functions
2554 the destructor as argument too, so that the caller can decide
2555 which destructor to use or whether to use destructor at all.
2556 Affected file lib/silcutil/silchashtable.[ch].
2558 * Fixed ID Cache purging. It actually deleted the entries from
2559 the hash table after the data was freed. The hash table ended
2560 up comparing freed memory. The affected file is
2561 lib/silccore/silcidcache.c.
2563 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Fixed Irssi SILC client's KILL command's HELP syntax.
2567 * The USERS command now resolves the detailed user information
2568 if the userinfo field is missing. Affected file is
2569 lib/silcclient/command_reply.c.
2571 * Do not print error in silc_file_read if the read file does
2572 not exist. Just silently return NULL. Affected file is
2573 lib/silcutil/silcutil.c.
2575 * Fixed the silc_log_output to not wine about NULL filename
2576 and to not create some bogus " " filename. Affected file is
2577 lib/silcutil/silclog.c.
2579 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Fixed various printing bugs on the user interface in the
2582 Irssi SILC Client. Minor changes that were forgotten from
2585 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Fixed the configure.in.pre and the compilation and distribution
2588 environment to support the new autoconf 2.52. That version is
2589 now required to compile the CVS trunk.
2591 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2594 to generally parse user@fqdn format strings. Affected file
2595 lib/silcutil/silcutil.c.
2597 * Added nickname_format and nickname_force_format fields to the
2598 SilcClientParams structure. The first one defines the format
2599 for the nicknames that the library will enforce if the receives
2600 multiple same nicknames. The second one is boolean value and
2601 can be used to force the library to always enforce the format
2602 to the nicknames regardles whether there are multiple nicknames
2603 or not. This configurable formatting was employed to flexibly
2604 support accessing multiple nicknames from the user interface.
2605 The userinterface can now set the nicknames to what ever format
2606 they prefer. Affected file lib/silcclient/silcapi.h.
2608 Added function silc_client_nickname_format to the file
2609 lib/silcclient/idlist.c. It performs the nickname formatting.
2611 Added new field `hostname´ to the SilcClientEntry context.
2612 It holds the hostname of the client. Affected file is
2613 lib/silcclient/idlist.h.
2615 * Irssi SILC Client sets the nicknames in nick@hostn format.
2616 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2617 irssi/src/silc/core/silc-core.c.
2619 The WHOIS printing now also shows both the real nickname and
2620 the formatted nickname so that user knows how to access the
2621 user if there are multiple same nicknames cached. Affected
2622 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2623 printing formatting too to take the hostname now as a separate
2624 argument. The Affected file is
2625 irssi/src/fe-common/silc/modules-formats.[ch].
2627 * Changed the silc_client_get_clients_local to accept the formatted
2628 nickname as argument. It accepts the real nickname too but the
2629 formatted nickname can be used to find the true entry from
2630 multiple entries. Affected file lib/silcclient/silcapi.h and
2631 lib/silcclient/idlist.c.
2633 * Added nickname_format_parse field to the SilcClientParams.
2634 It is a callback function provided by the application to parse
2635 the nickname out of the formatted nickname string. The library
2636 calls it to get the nickname from the formatted string. Since
2637 the application generally knows better the format of the nickname
2638 string it parses it instead of the library, even though library
2639 encodes the formatted string. If the callback function is not
2640 provided then the library will use the string as is. The
2641 affected file is lib/silcclient/silcapi.h.
2643 * All the nickname strings passed to the client library in
2644 commands are now expected to be formatted nickname strings.
2645 If the command does not support the formatted nickname string
2646 it will assume that the sent string is the actual nickname.
2647 Affected file lib/silcclient/command.c.
2649 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2651 * Added public key authentication support to OPER and SILCOPER
2652 commands in the client library. Affected file is
2653 lib/silcclient/command.c.
2655 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2657 * Changed the get_auth_methdod client operation to be asynchronous.
2658 It can be async if the application resolves the authentication
2659 method from the server during the negotiation. Added new
2660 SilcGetAuthMeth completion callback that the application will
2661 call after resolving the authentication method.
2663 Added function silc_client_request_authentication_method that
2664 the application can use to resolve the authentication method
2665 from the server. Added also SilcConnectionAuthRequest callback
2666 that the library will call after the server has replied. The
2667 application can call this function if it does not know the
2668 current authentication method.
2670 Affected files are lib/silcclient/client.c and
2671 lib/silcclient/silcapi.h.
2673 * The Irssi SILC client now automatically resolves the authentication
2674 method incase any configuration information is not present (and
2675 currently there never is). The affected file is
2676 irssi/src/silc/core/client_ops.c.
2678 * Fixed public key authentication from the client library.
2679 Affected file lib/silcclient/protocol.c. Changed also the
2680 protocol specification about the public key authentication in
2681 the connection authentication protocol. The actual data to be
2682 signed is now computed with a hash function before signing.
2684 * Fixed the public key authentication from the server as well.
2685 Affected file silcd/protocol.c.
2687 * Removed the mlock()'s from the memory allocation routines.
2688 Affected file lib/silcutil/silcmemory.c. The ./configure does
2689 not check anymore for the mlock(). Affected file is
2692 * Fixed USERS command in server to allow the execution of the
2693 command for private and secret channels if the client sending
2694 the command is on the channel. Affected file silcd/command.c.
2696 * Fixed silc_client_get_clients_local to return the clients
2697 count correctly. It could return wrong value. Affected file
2698 lib/silcclient/idlist.c.
2700 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2703 types. The assembler optimizations seemed not to like 64-bit
2704 data types. The assmebler optimizations thus are now enabled
2705 also for BSD systems as opposed to only enable them for Linux.
2707 * Do not check for threads at all on BSD systems. Affected
2708 file configure.in.pre.
2710 * Removed -n and -h options from the Irssi SILC Client since
2711 they are not used in silc.
2713 * Fixed the prime generation to assure that the first digit
2714 of the generated random number is not zero since our conversion
2715 routines does not like number strings that starts with zero
2716 digit. If zero digit is seen the random number is regenerated.
2717 This caused some corrupted RSA keys when the zero first digit
2718 was met. Affected file lib/silcmath/silcprimegen.c.
2720 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Fixed WIN32 configuration in the ./configure script.
2723 Fixed to include xti.h on environments that has it.
2724 Patches by Carsten Ilchmann and andrew.
2726 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Changed the silc_id_create_client_id to be collision
2729 resistant. It is now assured that there cannot be created
2730 two same client ID's. I suspect that some weird bugs in
2731 the server were actually caused by duplicate Client IDs.
2732 Affected file silcd/serverid.[ch]. A router receiving
2733 new ID now also assures and informs the sending server
2734 if the ID caused collision.
2736 * Changed the silc_id_create_channel_id to also assure that
2737 there are no collisions.
2739 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Statement about ignoring the Mutual Authentication flag when
2742 performing rekey with PFS was a bit misleading. It is ignored
2743 if it was set in the initial negotiation, it cannot be even
2744 set in the rekey. Fixed in the ke-auth draft. Started the
2745 new versions of the protocol drafts in the doc/.
2747 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Fixed a bug in silc_client_command_identify_save when saving
2750 new channel information. The channel name was no duplicated
2751 and caused crash on exit. Affected file is
2752 lib/silcclient/command_reply.c.
2754 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Fixed the getkey command handling in the server. Send just
2757 empty OK reply to the sender if the key could not be fetched
2758 (but everything else was ok, like the key just was not available).
2759 Changed the public key parameter to optional in the protocol
2760 specs so that empty OK reply can be sent. Affected file
2763 Added a message to Irssi SILC client to tell to user if the
2764 server did not return a public key.
2766 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2768 * Fixed a channel key regeneration bug. It registered new
2769 timeout tasks exponentially until all system resources were
2770 used. Affected file silcd/server.c.
2772 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Added the SILC Document generator to the scripts/silcdoc.
2775 It can be used to generate the Toolkit Reference Manual out
2776 of the source tree. Internally it will also use the RoboDoc
2777 generator now imported in util/robodoc.
2779 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2781 * Added couple of return's in rekey protocol if error orccurred
2782 during the protocol. The execution must be terminated.
2783 Affected file silcd/protocol.c. Also, terminate the protocol
2784 always with timeout.
2786 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * The client's Client ID was created initally from the wrong
2789 nickname (it could have been in format nick@host) in the
2790 silc_server_new_client. Affected file silcd/packet_receive.c
2792 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2794 * Added some SILC_LOG_ERROR's to various error conditions
2795 if client could not be added to ID cache. Affected files
2796 silcd/packet_receive.c and silcd/server.c.
2798 * When client's sock->user_data is freed, NULL also the
2799 client->router and client->connection pointers. Added check
2800 for these pointers being NULL to various places around the
2801 code. Affected file silcd/server.c.
2803 * Added client->data.registered == TRUE checks to various
2804 places around the code to assure that unregistered client's
2805 are not handled when it is not allowed. Affected file
2808 * Added `bool registered' fields to all
2809 silc_idlist_[server|client]_get_* routines to indicate whether
2810 the fetched client needs to be registered or not. Affected
2811 file silcd/idlist.[ch].
2813 * Add your own entry as registered to the ID cache in the
2814 server. Affected file server.c.
2816 * Fixed a bug in silc_server_new_server. The SilcServer was
2817 set as the new server's context instead of SilcServerEntry.
2818 This naturally caused some weird bugs.
2820 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2822 * Do not delete the channel rekey task when adding it
2823 for in silc_server_create_channel_key.
2825 * Changed the silc_server_create_channel_key to return
2826 TRUE or FALSE to indicate the success of the channel key
2829 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2831 * Fixed MSVC++ project files and added missing files to
2832 Makefiles under win32/.
2834 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2836 * Do not add TCP_NODELAY flag if the operating system
2837 does not have it defined. Affected files are
2838 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2840 * Fixed buffer overflow from Irssi SILC Client. Affected
2841 file irssi/src/fe-common/core/themes.c.
2843 * Fixed double free in client library in the file
2844 lib/silcclient/client.c when disconnecting from server.
2846 * Applied double free patch from cras to Irssi SILC client.
2847 Affected files irssi/src/core/[modules/expandos].c
2849 * Fixed the disconnection handling to Irssi SILC Client.
2850 The application must call silc_client_close_connection
2851 in ops->connect client operation in case of failure of
2852 the connection. Affected file is
2853 irssi/src/silc/core/client_ops.c.
2855 * Do not set sock->protocol to NULL in the function
2856 silc_client_close_connection after executing the protocol's
2857 final callback since the sock might not be valid anymore.
2858 Affected file lib/silcclient/client.c.
2860 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Do not enable SILC_THREADS if the linking with libpthread
2863 did not happen. Affected file configure.in.pre.
2865 * Added notion to protocol specification that server must
2866 verify the sent authentication payload with CMODE when
2867 setting the channel founder key. Implemented it to the
2868 server. Affected file silcd/command.c.
2870 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Added _EXTRA_DIST SILC distribution variable to the
2873 distributions file. It is used to conditionally add extra
2874 files or directories to the specific distribution. Affected
2875 files ./prepare, Makefile.am.pre and distributions.
2877 Removed the `_' from the start of the distribution names.
2880 * Added README.WIN32 for instructions to compile the Toolkit
2883 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Fixed a double free in disconnection in the server. Affected
2886 file is silcd/server.c.
2888 * Fixed the lib/silcske/groups.c to work now also with GMP
2889 MP library. The string conversion did not work when using
2890 specific base and the base is indicated in the string as well.
2892 * Created win32/ directory which now includes MSVC++ specific
2893 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2894 It will appear only in the toolkit distribution
2896 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2898 * Changed the key material distribution function in case when
2899 the hash output is too short. The data is now concatenated
2900 a bit differently than it used to. Made the change to the
2901 SKE protocol specification.
2903 * Added better GMP detection to configure.in.pre. A patch
2906 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Fixed a minor bug in SKE that might cause some problem on
2909 some platforms. Affected file lib/silcske/silcske.c.
2911 * Added the cookie checking for initiator in the SKE. It checks
2912 that the responder returns the sent cookie unmodified. The
2913 affected file is lib/silcske/silcske.c. Added new SKE
2914 error type INVALID_COOKIE that can be sent during the
2915 negotiation. Fixed some memory leaks as well.
2917 * Added the "invalid cookie" error message to Irssi SILC client's
2920 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Added `task_max' field to the SilcClientParams to indicate
2923 the maximum tasks the scheduler can handle. If set to zero,
2924 default values are used. Affected file lib/silcclient/silcapi.h.
2926 * Fixed memory leaks in silc_client_close_connection. Affected
2927 file lib/silcclient/client.c.
2929 * Added silc_client_del_client_entry to client library to free
2930 all memory of given client entry. Affected file is
2931 lib/silcclient/idlist.[ch].
2933 * Added new functions silc_client_del_channel and
2934 silc_client_del_server to delete channel and server entries.
2935 Affected file lib/silcclient/[silcapi.h/idlist.c].
2937 * Removed silc_client_del_client_by_id from silcapi.h.
2939 * Fixed the INFO command to return the server's own info
2940 correctly when querying by Server ID. Affected file is
2943 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Removed the non-blocking settings in WIN32 code in the
2946 silc_sock_[read/write] and added SleepEx instead. Affected
2947 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2948 of input data is now checked with FIONREAD and ioctlsocket.
2950 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Call silc_schedule_task_del_by_context in the
2953 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2954 Affected file lib/silccore/silcprotocol.c.
2956 * Call silc_protocol_cancel for active protocols in the
2957 silc_server_close_connection if the funtion
2958 silc_server_free_sock_user_data has not been called.
2959 Affected file silcd/server.c.
2961 * Generic tasks cannot be deleted using the del_by_fd
2962 task deleting function since generic tasks does not match
2963 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2965 * Added a notion to SILCOPER help file that the SILCOPER works
2966 only on router server, not on normal server.
2968 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Added for WIN32 support for the new scheduler as well.
2971 Affected file lib/silcutil/win32/silcwin32schedule.c.
2973 * Fixed the SHA1 implementation to work on various platforms.
2975 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2978 API. It is part of the scheduler now. Everything else is
2979 as previously but some functions has changed their names.
2980 Checkout the lib/silcutil/silcschedule.h for the interface.
2981 Updated all applications to use the new interface. Affected
2982 files are lib/silcutil/silcschedule.[ch].
2984 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Found a bug in the SKE implementation. The HASH value,
2987 specified by the protocol, was not computed correctly. The
2988 public key of the responder was not added to the computation
2989 even though it is mandatory. Affected file lib/silcske/silcske.c.
2990 This unfortunately causes incompatibilities with older
2991 clients and servers.
2993 * Added WIN32 specific network init and uninit functions:
2994 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2995 the Winsock2. Affected file lib/silcutil/silcnet.h and
2996 lib/silcutil/win32/silcwin32net.c.
2998 * Set the socket always to nonblocking mode on WIN32 after
2999 reading data or writing data. Affected file is
3000 lib/silcutil/win32/silcwin32sockconn.c.
3002 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Fixed various compilation problems under WIN32. Affected
3005 files lib/silcutil/win32/silcwin32thread.c and
3006 lib/silcutil/win32/silcwin32schedule.c.
3008 * Removed all _internal.h #includes from public header
3009 files. Internal headers must never be included from
3012 Removed also the lib/silcske/payload_internal.h file.
3014 * All include files that may be needed (public and some others
3015 included by the public headers) by application developers are
3016 now copied to the ./includes directory. It does not copy any
3017 internal headers. Affected file Makefile.defines.pre and all
3018 Makefile.am's under lib/ and subdirs.
3020 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Do not change the ~/.silc directory's permissions automatically.
3023 Affected file irssi/src/silc/core/clientutil.c.
3025 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Do not cancel the protocol in silc_server_close_connection
3028 it might cause recursion. Now cancelled in the function
3029 silc_server_free_sock_user_data. Affected file silcd/server.c.
3031 * Fixed the silc_server_remove_clients_by_server to regenerate
3032 the channel keys correctly finally. Added also new function
3033 silc_server_remove_clients_channels to actually do it.
3034 Affected file silcd/server.c.
3036 * Fixed the silc_server_new_channel to not crash by giving
3037 wrong router to the new channel. Affected file is
3038 silcd/packet_receive.c.
3040 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3043 which is given as argument to the silc_client_alloc now.
3044 It can be used to configure the client and set various parameters
3045 that affect the function of the client.
3047 * The USERS command in server did not check whether the channel
3048 is private or secret. Affected file silcd/command.c.
3050 * Added new argument to the USERS command in protocol specification.
3051 The USERS command now can take the channel name as argument
3052 as well. Added support for this in client and server and
3053 updated the protocol specs.
3055 * Completed the GETKEY command in client. It can be now used
3056 to fetch also servers public key not only some clients.
3057 Affected files lib/silcclient/command[_reply].c.
3059 * Added silc_client_get_server to return server entry by the
3060 server name. Affected files lib/silcclient/silcapi.h and
3063 * Redefined the IDENTIFY command in protocol specification to be
3064 more generic. It now can be used to query information about
3065 any entity in the SILC Network, including clients, servers and
3066 channels. The query may be based either the entity's name
3067 or the ID. Added support for this in both client and server.
3069 Affected files silcd/command.c and lib/silcclient/command.c
3070 and command_reply.c.
3072 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3073 the _from_client and _from_server functions. Affected file
3076 * Added silc_client_get_channel_by_id_resolve to the file
3077 lib/silcclient/silcapi.h to resolve channel information by
3078 its ID. Added also silc_client_get_channel_by_id that
3079 does not resolve it from the server.
3081 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Added SilcServerEntry context into the client library
3084 to represent one server. The INFO command now allocates
3085 these to save the resolved server info. For now on the
3086 client library will also keep information about servers,
3087 connected and resolved with INFO.
3089 The INFO command now allocates the SilcServerEntry context
3090 and saves the server info there. The COMMAND_REPLY in
3091 the INFO now returns the parameters to application in
3092 same order as defined in the protocol specification.
3094 The entries are cached in the client->server_cache.
3096 * The INFO command is now issued after received the Client ID
3097 from the server. Affected file lib/silcclient/client.c.
3099 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3100 to the application as the mode changer might be server.
3101 It is guaranteed that NULL is not returned anymore to the
3102 application. Affected file lib/silcclient/client_notify.c.
3104 The ID Type is now also passed to the application so that
3105 it can check whether the returned entry is SilcClientEntry
3108 Added new function silc_client_get_server_by_id to return
3109 the server entry by ID. Affected files are the
3110 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3112 * Do not create the channel in the Irssi SILC Client when issuing
3113 the JOIN command but when received the sucessful JOIN command
3114 reply. Otherwise the channel might get created even though we
3115 could not join it. The Affected file is
3116 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3118 * Fixed a channel joining bug in router. The router must also
3119 check the channel modes, invite and ban lists etc. when serving
3120 the JOIN command sent by normal server. Affected file is
3121 silcd/command.c. The router now resolves the client's
3122 information from the server who sent the JOIN command if it
3123 does not know it, and processes the JOIN command only after
3126 * Changed the SilcCommandCb to take new argument; void *context2.
3127 Affected file lib/silccore/silccommand.h
3129 The second argument in the command callbacks in the server now
3130 includes the SilcServerCommandReplyContext if the command was
3131 called as pending command callback from the command reply.
3132 Otherwise it is NULL. When called as pending the status of the
3133 command reply will be checked and if it was erronous the
3134 error will be sent to the original sender of the command.
3135 This way the client always receives the error messages even
3136 though the server was actually the one who received the error
3137 when it resent the command to router, for example. Affected
3138 files silcd/command[_reply].[ch].
3140 * Fixed sending WHOWAS command's error message to client if
3141 the requested client could not be found. It was missing.
3144 * Changed the CMODE and CUMODE commands reply arguments in the
3145 protocol specification. The Channel ID is now sent in both
3146 of the commands to identify the channel. Implemented this
3147 new feature to the client and server. Affected files
3148 lib/silcclient/command_reply.c and silcd/command.c.
3150 * Made better checks for invite and ban lists in the JOIN
3151 command in server. Affected file silcd/command.c.
3153 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * The server now performs the incoming host IP/DNS lookup
3156 using the silc_socket_host_lookup and thus does not block
3157 the server anymore. Affected file silcd/server.c.
3159 * Completed the multi-thread support for SILC Scheduler in
3160 the lib/silcutil/silcschedule.c.
3162 * Fixed the configure.in.pre to detect the pthread correctly
3165 * Fixed a deadlock in silc_task_queue_wakeup in the file
3166 lib/silcutil/silctask.c.
3168 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3170 * Added new function silc_schedule_wakeup that is used in
3171 multi-threaded environment to wakeup the main thread's
3172 schduler. It needs to be used when a thread adds a new task
3173 or removes a task from task queues. After waking up, the
3174 scheduler will detect the task queue changes. If threads
3175 support is not compiled in this function has no effect.
3176 Implemented the wakeup mechanism to both Unix and WIN32
3177 systems. Affected files are lib/silcutil/silcschedule.[ch],
3178 lib/silcutil/unix/silcunixschedule.c and the
3179 lib/silcutil/win32/silcwin32schedule.c.
3181 * Added new function silc_task_queue_wakeup to wakeup the
3182 scheduler by the specified task queue. Affected file
3183 lib/silcutil/silctask.[ch].
3185 * The silc_socket_host_lookup_start now wakes up the scheduler
3186 after adding the timeout task. Affected file is
3187 lib/silcutil/silcsockconn.c.
3189 * The silc_socket_host_lookup is synchronous now if the threads
3190 support is not compiled in. However, the callback is still
3191 called asyncronously through the scheduler, anyway. Affected
3192 file lib/silcutil/silcsockconn.c.
3194 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Added new function silc_socket_host_lookup to perform
3197 asynchronous IP and FQDN lookups for the socket connection.
3198 Affected files lib/silcutil/silcsockconn.[ch].
3200 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3203 that may or may not compile the mutex support in.
3205 Changed the silc_mutex_alloc interface. It allocates the
3206 mutex now to the sent pointer and returns TRUE or FALSE.
3208 Affected file lib/silcutil/silcmutex.h.
3210 * Wrote the SILC Task Queue interface to support multi-threads.
3211 Affected file lib/silcutil/silctask.[ch].
3213 * Wrote the SILC Scheduler to support multi-threads. Affected
3214 file lib/silcutil/silcschedule.c.
3216 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3219 in lib/silcutil/win32/.
3221 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Defined SILC Mutex API and SILC Thread API and implemented
3224 them for Unix. Affected files are
3225 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3226 lib/silcutil/unix/silcunixmutex.c and
3227 lib/silcutil/unix/silcunixthread.c.
3229 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Fixed the silc_server_remove_clients_by_server's channel
3232 key re-generation. The hash table handling was incorrect
3233 and would not work with many channels. Affected file is
3236 * Fixed some memory leaks around the server code.
3238 * Rewrote the silc_server_get_users_on_channel to support IPv6
3239 based Client ID's. Affected file silcd/server.c.
3241 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3242 specification. However, a separate document must be written
3243 to define the detailed signing procedure and the payload
3244 associated with the flag. Defined the flag to the
3245 lib/silccore/silcchannel.h as well.
3247 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Changed the dynamic tables to static size tables in the
3250 lib/silccrypt/silchmac.c.
3252 * Removed GCC dependencies from the code. A patch by cras.
3254 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3256 * Do not show the error "Error receiving packet bla bla"
3257 in server if it really was not an error (-2 means that reading
3258 is pending). Affected file silcd/server.c.
3260 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3262 * Fixed a possible crash in silc_server_remove_clients_by_server
3263 in silcd/server.c. Fixed there also some memory leaks.
3265 * Fixed the silc_idlist_replace_client_id. It could replace
3266 wrong key in the hash table. Affected file silcd/idlist.c.
3268 * Do not check whether there are global users on the channel
3269 if the channel->global_users is FALSE. Affected functions
3270 silc_server_remove_from_one_channel and
3271 silc_server_remove_from_channels in silcd/server.c. Also,
3272 do not check if the removed client is local as we can be
3273 sure that global client was not removed from the channel
3274 and checking for global users is not needed.
3276 * The silc_server_remove_clients_by_server now re-generates
3277 the channel keys correctly for those channels that had
3278 clients removed from them. Affected file silcd/server.c.
3280 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Found the reason of random crashes in the server. We weren't
3283 ignoring the SIGPIPE signal (which can be sent in write())
3284 and it crashed the server. Affected file silcd/silcd.c.
3286 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3288 * Assure that sock->user_data is not NULL in the function
3289 silc_server_packet_send in silcd/packet_send.c.
3291 * Disconnect the remote connection if it could not be added
3292 to any ID lists in the server. The affected file is
3295 * Check in silc_server_packet_send[_real/dest] that the
3296 socket is not disconnecting and ignore the data if it is.
3297 Affected file silcd/packet_send.c.
3299 * Define inline to __inline on native WIN32 compilation.
3300 Affected file includes/silcwin32.h.
3302 * Added some explicit type casts for inline code since MSVC
3303 require them. Affected files lib/silcutil/silcbuffer.h,
3304 lib/trq/silcdlist.h and lib/trq/silclist.h.
3306 * Print warning in log files from now on if the packet
3307 decryption fails. Affected file silcd/server.c.
3309 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Changed the `say' client operation's interface to accept
3312 new `type' argument to indicate the type of the message sent
3313 by the library. The application may filter the library's
3314 messages according the type. The affected file is the
3315 lib/silcclient/silcapi.h.
3317 * Added two new functions to lib/silcclient/silcapi.h:
3318 silc_client_del_client and silc_client_del_client_by_id.
3319 Affected file lib/silcclient/idlist.c.
3321 * Moved the clientincludes.h from includes/ to silc/ and
3322 serverincludes.h from includes/ to silcd/.
3324 * The modes for the CMODE and CUMODE are now passed as
3325 uint32 for application with COMMAND_REPLY. The affected
3326 file is lib/silcclient/command_reply.c.
3328 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * /WHOIS without arguments shows client's own information.
3331 Affected file lib/silcclient/command.c.
3333 * Changed PING to not accept any arguments. The specs
3334 says that client can ping only the connected server so
3335 requiring an argument is not needed. Affected file is
3336 lib/silcclient/command.c.
3338 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Fixed a fatal bug in private message sending and reception
3341 encryption and decryption when using private message keys.
3342 The implementation was incorrect and did not follow the
3343 specification. It causd that some of the message were
3344 lost since it did not use the sending and receiving keys
3345 as the protocol suggests. This has been fixed and will cause
3346 incompatibilities with older clients when sending private
3347 message encrypted with private message keys. Affected files
3348 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3349 and various other in Irssi SILC Client.
3351 Added `responder' boolean argument to the functions
3352 silc_client_add_private_message_key[_ske] to indicate when
3353 the key is added as responder or initiator of the key
3356 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3358 * Removed the silc_ske_check_version function and created
3359 a SilcSKECheckVersion callback. Added also a function
3360 silc_ske_set_callbacks that is now used to set all SKE
3361 callbacks. The callback functions are not given to
3362 the SKE functions anymore, but this function is used to
3365 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3367 * Added `silc_version' argument to the silc_client_alloc
3368 to define the version of the application for the library.
3369 The library will use the version string to compare it
3370 against the remote host's (usually a server) version
3371 string. Affected file lib/silcclient/silcapi.h
3373 * Added the KE protocol context to Key Agreement context
3374 in client library so that we can abort the SKE if it
3375 is in process when we get timeout. Affected file is
3376 lib/silcclient/client_keyagr.c.
3378 * Do not resolve the client ID forever if it returns in the
3379 first time that such client does not exist. This was done
3380 for example with private message. Affected file is
3381 lib/silcclient/client_prvmsg.c.
3383 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Do not add regex.h for WIN32. The affected file
3386 includes/silcincludes.h.
3388 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3389 not work yet 100%. It generates the DLL's automatically
3390 when compiling with --with-win32 under cygwin.
3392 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3394 * lib/contrib/regex.c is not compiled on WIN32.
3396 * Added silc_net_get_socket_opt function to the
3397 lib/silcutil/silcnet.h.
3399 * Added includes/silcwin32.h for WIN32 specific includes
3402 * Do not use ptime structure or any of the posix process
3403 functions on WIN32 in lib/silccrypt/silrng.c.
3405 * Added silc_gettimeofday to provide generic function
3406 for struct timeval on all platforms. Added the function
3407 to lib/silcutil/silcutil.h.
3409 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3412 library as they clearly belong there. As a plus side we
3413 can make the actual socket connection routines platform
3416 Added also new generic function silc_socket_read and
3417 silc_socket_write (that used to be silc_packet_[read/write].
3418 The implementation of these are platform specific.
3420 * Added WIN32 specific routines of silc_socket_[read/write]
3421 to lib/silcutil/win32/silcwin32sockconn.c.
3423 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * Added preliminary support for native WIN32 compilation under
3426 cygwin (using the -mno-cygwin option for GCC) to the
3427 ./configure.in.pre. The --with-win32 now prepares the
3428 compilation for native WIN32.
3430 * Rewrote the SILC Scheduler interface in the file
3431 lib/silcutil/silcschedule.h. The scheduler is now context
3432 based and does not have anymore any global static scheduler.
3433 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3434 and created lib/silcutil/win32 directory for WIN32 based
3437 * Added Unix specific network routines to the
3438 lib/silcutil/unix/silcunixnet.c and the old
3439 lib/silcutil/silcnet.c includes now only generic routines.
3441 Added WIN32 specific network routines to the
3442 lib/silcutil/win32/silcwin32net.c.
3444 * Added Unix specific utility functions from the
3445 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3447 * Added WIN32 SILC Scheduler to the file
3448 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3451 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3453 * Do not handle JOIN notify in the server if the target client
3454 is not registered (idata->registered == FALSE). The affected
3455 file is silcd/packet_receive.c.
3457 * Update the nickrec->founder in event_cumode in the Irssi SILC
3458 client. Affected file irssi/src/silc/core/silc-channels.c.
3460 * Fixed the CUMODE_CHANGE notify handling in the server when
3461 server and router are announcing their clients on channels.
3462 Now the mode changes are saved and notified correctly. The
3463 affected file is /silcd/packet_receive.c.
3465 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3466 They really did not replace the cache entry in the ID Cache.
3467 Now they do that. Affected file silcd/idlist.c.
3469 * Fixed the KICK notify handling in the Irssi SILC client to
3470 update the channel records so that the kicked client does not
3471 appear to be on the channel. The affected file is
3472 irssi/src/silc/core/silc-channels.c.
3474 * Always update the conn->current_channel when executing command
3475 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3477 * Fixed the KILL notify handling in Irssi SILC client to remove
3478 the killed client on all channels.
3480 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Fixed the silc_parse_command_line to remove extra spaces
3483 from the start and end of the arguments. Affected file is
3484 lib/silcutil/silcutil.c.
3486 * Cancel and free any active protocol in the function
3487 silc_server_close_connection. Affected file silcd/server.c.
3489 * Cancel and free any active protocol in the function
3490 silc_client_close_connction. Affected file is
3491 lib/silcclient/client.c.
3493 * Do not execute the KILL command for clients that are in
3494 history (ie. they are not in the network). Affected file is
3497 * Fixed KILL notify handling, client does not crash anymore.
3498 Affected file irssi/src/silc/core/silc-channels.c.
3500 * Reduced the default packet buffer size from 2048 to 1024 in
3501 lib/silccore/silcpacket.c.
3503 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3504 counter to the SKE context that is incresed when the SKE library
3505 performs async operation outside the library. If the outside
3506 process frees the SKE context and FREED status will be set
3507 and the library will detect after the sync operation that the
3508 libary is freed. The affected files are
3509 lib/silcske/silcske[_status].[ch].
3511 * Resolve the client entry information in the function
3512 silc_client_channel_message to assure that NULL pointer is not
3513 passed as client entry to the application. */
3515 * Fixed the task timeout calculation to assure that there is
3516 never negative timeouts. The affected file is
3517 lib/silcutil/silcschedule.c.
3519 * Fixed the channel user mode notification sending in server.
3520 It was sent point-to-point to the router (or to server by router)
3521 but it needs to be destined to a channel. The routines now
3522 supports sending the channel user mode notifys to the channels
3523 when announcing clients and channels. Affected files are
3524 silcd/server.c and silcd/packet_receive.c.
3526 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3527 It did not actually replace the old channel entry in the cache.
3528 Affected file lib/silcclient/client_notify.c.
3530 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Fixed a possible crash in silc_packet_send_prepare. It now
3533 assures always that there is enough space in the buffer and
3534 at the tail area of the buffer (for MAC).
3536 Fixed the inbound buffer reallocation in silc_packet_read.
3537 It was old code and did not handle the reallocation correctly.
3540 The affected file is lib/silccore/silcpacket.c.
3542 * Fixed buffer overflow in silc_parse_nickname in the file
3543 lib/silcutil/silcutil.c.
3545 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * make install generates new server keys only if there is not
3550 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3553 Added check that if the NOREPLY is set then we will not send
3554 the away message. This avoids infinite loop of away messages
3555 if both clients are away. The affected file is
3556 lib/silcclient/client_prvmsg.c.
3558 * Fixed client crash if /NICK was given without arguments.
3559 Affected file lib/silcclient/command.c.
3561 * Server does not send the invite list in INVITE command back
3562 to the client if the list was not altered. Added this notion
3563 to the protocol spec as well. Affected file silcd/command.c.
3565 Fixed possible crash in INVITE command by checking the
3566 value of silc_server_get_client_route command.
3568 * Fixed the INVITE notify type handling. The arguments are now
3569 taken in correct order and client does not crash. The affected
3570 file is irssi/src/silc/core/silc-channels.c.
3572 Removed the "Inviting xxx to channel" message from the
3573 client library away and let the application handle it.
3574 Affected file lib/silcclient/command.c. Added that message
3575 to Irssi SILC client's message formats.
3577 * Fixed CMODE command crash in client. It now checks the
3578 amount of arguments correctly and does not crash. The affected
3579 file is lib/silcclient/command.c.
3581 * Do not create new channel automatically in silc_channels_join
3582 but check whether the channel by that name already exists.
3583 Affected file irssi/silc/core/silc-channels.c.
3585 * Do not send the SERVER_SIGNOFF to router if the disconnected
3586 entity was the router. Affected file silcd/server.c.
3588 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3589 SILC client as it was missing from there.
3591 Added the handling of the KICK notify to the Irssi SILC client
3592 as it was missing. Added "you have been kicked" message to
3593 Irssi SILC client's message modules formats.
3595 Added the handing of the KILL notify to the Irssi SILC client
3596 as it was missing. Added the kill message module formats
3599 The affected file is irssi/src/silc/core/silc-channels.c.
3601 * The router did not save the channel mode the server announced.
3602 Affected file silcd/packet_receive.c.
3604 * Fixed a possible crash in INFO command in server. If the
3605 server did not provide the server info it crashed. Affected
3606 file silcd/command.c.
3608 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Fixed the GETKEY command in the server to check also the
3611 global list. Otherwise the GETKEY would not work correctly
3612 in normal SILC server. Affected file silcd/command.c.
3614 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Fixed GETKEY crash, it crashed if the command did not succseed.
3618 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3621 is now real and not just an macro interface to GMP.
3623 Removed the entire GMP from the source tree and imported new
3624 NSS MPI library instead. Reason for removing GMP is that it is
3625 extremely large and compiles extremely slow. The NSS MPI
3626 is only a few files and compiles in less than 10 seconds.
3627 The speed is also about the same as GMP. The MPI is imported
3628 to lib/silcmath/mpi.
3630 If the system has GMP installed we will still use the GMP.
3631 If it is not then the NSS MPI will be compiled.
3633 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Merged a long nickname (127 characters long) crash bugfix from
3636 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3638 * Merged a freed memory reference bugfix from Irssi CVS tree.
3639 Affected file irssi/src/core/commands.c.
3641 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Added the server's public key sving and verification to the
3644 server when performing the SKE. This was missing and the
3645 remote server's (or router's) public key was accepted without
3646 checking whether we have it previously or trust it at all.
3647 Affected file silcd/protocol.c.
3649 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Check in the silc_server_timeout_remote if protocol is active
3652 and make sure that the protocol's final callback is called so
3653 that all memory if freed. Affected file silcd/server.c.
3655 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * silc_server_whois_send_reply crashed the server if the nickname
3658 was 127 characters long. Affected file silcd/command.c.
3660 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Added sanity check to the silc_server_new_client. If the hostname
3663 is provided inside username then check that the provided hostname
3664 really is the same as the resolved one. If the hostname was not
3665 resolved then check it from the public key. Affected file is
3666 silcd/packet_receive.c.
3668 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3669 if the server disconnected us and the connection is not valid
3670 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3672 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3673 the library to the lib/silcutil/silcutil.[ch].
3675 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Close log file after open. Affected file
3678 lib/silcutil/silclog.c.
3680 * Check whether sock == NULL in silc_client_send_packet and return
3681 if it is. Affected file lib/silcclient/silcclient.c.
3683 * Check rec->entry == NULL in the Irssi SILC Client before
3684 sending the channel message. Affecte file is
3685 irssi/src/silc/core/silc-servers.c.
3687 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Merged a splitted window bugfix from Irssi CVS tree. The
3690 affected file is irssi/src/fe-text/textbuffer-view.c.
3692 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3693 It did not print nickname.
3695 * Improved the distributions system a bit.
3697 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3700 irssi/src/fe-text/gui-window.c.
3702 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3703 to in-active server. The affected file is
3704 irssi/src/silc/core/client_ops.c.
3706 * Resolve the client in USERS command reply if the entry does
3707 not have username resolved. The affected file is
3708 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3709 command to WHOIS command to really resolve stuff. The USERS
3710 is not used any more in any critical section so WHOIS can
3711 be used even though it might be slower than IDENTIFY.
3713 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3716 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3718 * Changed the protocol API a bit more consistent in the
3719 lib/silccore/silcprotocol.[ch].
3721 * Changed the following headers to ROBODoc format:
3723 lib/silccore/silcpayload.h
3724 lib/silccore/silcprotocol.h
3725 lib/silccore/silcsockconn.h
3727 All core library headers are now formatted.
3729 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Fixed a bug in Irssi SILC client; do not show that you are
3732 server/router operator if you really are not. Affected file is
3733 irssi/src/silc/core/client_ops.c.
3735 * Renamed silc_command_free_payload to silc_command_payload_free.
3736 Affected file lib/silccore/silccommand.h
3738 * Added silcmath.h to include the prototoypes of various routines
3739 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3742 * Changed the following headers to ROBODoc format:
3744 lib/silccore/silcchannel.h
3745 lib/silccore/silccommand.h
3746 lib/silccore/silcid.h
3747 lib/silccore/silcidcache.h
3748 lib/silccore/silcmode.h
3749 lib/silccore/silcnotify.h
3750 lib/silccore/silcpacket.h
3751 lib/silcmath/silcmath.h
3753 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Added checking to the server code not to start the server if
3756 ciphers and stuff are not configured properly. Affected files
3757 silcd/serverconfig.[h] and silcd/server.c.
3759 * Changed the layout of the header files of the public interfaces
3760 in the SILC libraries. The new layout supports ROBODoc
3761 documentation tool (and some others) so that it is easy to create
3762 a library reference manual. All the other headers and source
3763 code must still follow the CodingStyle document. Also source
3764 code must not include these ROBODoc stuffs, only the headers.
3765 Furthermore, all public interface headers must now be named
3766 by using `silc' prefix, example: silcapi.h, silccipher.h.
3767 Some files were renamed due to this. All the other headers
3768 must not be used as public interfaces. I will update the
3769 CodingStyle document later. Changed following headers, so far:
3771 lib/silcclient/silcapi.h
3772 lib/silccore/silcauth.h
3773 lib/silccore/silcprivate.h
3774 lib/silccrypt/silcdh.h
3776 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Removed silc_client_packet_send_flush from the client library
3781 as it is not needed. Affected file lib/silcclient/client.[ch].
3783 * Added printing of message of unresolved authentication method
3784 to the Irssi SILC client. Added it to the module formats.
3785 Removed the same message from the client library.
3787 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Added new distribution feature, DISTLABEL. Every distribution
3790 can define own preprocessor label that can be used in the
3791 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3792 file distributions, acconfig.h.pre and prepare.
3794 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3796 * Added Makefile.defines_int to include the actual definitions
3797 for Makefile.defines.in. Tested the new distribution system,
3798 created distributions and tested installation.
3800 * Added AWAY message printing to the Irssi SILC client. Added
3801 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3803 * Added SCONNECT command to call the SILC's CONNECT command.
3804 Cannot use CONNECT directly since Irssi uses that internally.
3805 Affected file irssi/src/silc/core/silc-servers.c.
3807 Added ACTION local command. It is same as ME command but takes
3808 the channel as mandatory argument.
3810 Rewrote some of the Irssi's help files to suite for SILC
3813 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added Makefile.defines[.in] that should for now on be included
3816 in all Makefile.am file in the source tree. That file includes
3817 all common compilation definitions for SILC source tree.
3819 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Minor changes to the ./prepare script to change the package
3822 name according the distribution name to the configure.in.
3824 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Created new distribution system. Added file `distributions'
3827 that defines all the distributions that can be created out of
3828 the SILC source tree. The ./prepare script now reads that
3829 file to determine how to prepare the distributions. The
3830 first argument to the ./prepare is the name of the distribution
3831 and second is the version of the distribution. If given
3832 without arguments it creates the default (toolkit) distribution
3833 with the default version (defined in ./prepare).
3835 All Makefile.am files that are subject to the distributions
3836 are now named as Makefile.am.pre. These are ./Makefile.am
3837 and lib/Makefile.am. Others may be changed later.
3839 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Added invite list, ban list, some key management and connection
3842 error message printing to module formats in the Irssi SILC client.
3844 * Added new silc_client_set_away_message to set the away message
3845 that is back to the person who sent private message. The
3846 affected file lib/silcclient/silcapi.h and the
3847 lib/silcclient/client_prvmsg.c.
3849 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Fixed the private message sending in the Irssi SILC client,
3852 added local command KEY to the Irssi SILC client.
3854 Added key management and key agreement message formats to the
3855 irssi/src/fe-common/silc/module-formats.[ch].
3857 Added USERS (alias WHO) printing, server/router operator
3858 indication and LIST command printing to the module formats.
3860 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Fixed channel joining notify handling, cumode notify handling
3863 from Irssi SILC client.
3865 * Added SILC specific module-formats to the Irssi SILC client so
3866 that SILC specific message hilighting, colors etc is possible.
3867 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3869 Added channel mode, channel user mode, actions, notices,
3870 whois and whowas printing to the the module-formats.c.
3872 * Fixed a bug in channel deletion in the server. The channel
3873 is not left to the cache even if the channel founder auth mode
3874 is set when there are no users anymore on the channel. Affected
3875 file silcd/server.c.
3877 * The silc_net_localhost now resolves the entire hostname including
3878 the domain name. Affected file lib/silcutil/silcnet.c.
3880 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Changed the ask_passphrase client operation to be ascynchronous.
3883 It has now a completion callback and a context that the
3884 application must call after it has got the passphrase from
3885 the user. Affected files lib/silcclient/silcapi.h,
3886 lib/silcclient/protocol.c, lib/silcclient/command.c and
3889 Added SilcAskPassphrase callback that the application calls
3890 to deliver the passphrase to the library.
3892 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3893 The public key verification and especially a certificate
3894 verification is asynchronous procedure.
3896 Added new SILC_SKE_STATUS_PENDING status to indicate the
3897 request is pending and a callback will be called to finalize
3900 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3901 indicate that remote end did not send its public key (or
3902 certificate), even though we require it. Added check for this
3903 condition in the SKE. This was a security bug, now fixed.
3905 Defined new SilcSKEVerifyCbCompletion callback that is called
3906 when the verification process is completed.
3908 The affected files lib/silcske/silcske_status.h and
3909 lib/silcske/silcske.[ch].
3911 * Changed the verify_public_key client operation to be async
3912 as well. Defined SilcVerifyPublicKey callback that is used to
3913 indicate the success of the public key verification process.
3915 Changed the server and client to use the new async client
3918 * Changed the Irssi SILC client's internal scheduler to be called
3919 twice as many times as it used to be. As a result the client
3920 should be a bit faster now. Affected file is
3921 irssi/src/silc/core/silc-core.c.
3923 * Added support to Irssi SILC client of asynchronous public key
3924 verification and passphrase inquiry. Affected file is
3925 irssi/src/silc/core/silc-core.c.
3927 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Do not say "You have left channel %s" in client library.
3930 Moved it to the application. Affected files are
3931 lib/silcclient/command.c and silc/client_ops.c.
3933 * Fixed silc_client_get_clients. Command context was not
3934 duplicated and was freed memory in the callback. Affected
3935 file lib/silcclient/idlist.c.
3937 * Do not say "you are now talking..." on JOIN command in the
3938 client library. The appliation must handle it.
3940 * Do not say ".. changed topic to" in command reply in the
3941 client libary. The application must handle it.
3943 * Fixed TOPIC command sending in the client library.
3945 * Fixed a memory leak in silc_client_command_free in the file
3946 lib/silcclient/command.c.
3948 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Imported a modified version of Irssi client to the source tree.
3951 The Irssi will be used to create a new client called
3952 Irssi SILC. Imported to irssi/.
3954 Added silc_core_init_finish function to the Irssi. Affected
3955 file irssi/configure.in.
3957 A lot changes in the Makefile.ams around the irssi tree.
3959 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Do not rehash if the new size is same as the old size of the
3962 hash table, in the silc_hash_table_rehash*. The affected file
3963 lib/silcutil/silchashtable.c.
3965 * Replaced hash_table_del_by_context calls from the server
3966 (when channel->user_list and client->channels) to the
3967 hash_table_del as it is sufficient and faster.
3969 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Added silc_hash_table_list, silc_hash_table_get and the
3972 SilcHashTableList structure to provide an alternative way to
3973 traverse the hash table. The affected files are
3974 lib/silcutil/silchashtable.[ch].
3976 * Changed the server's idlist routines to use the hash table
3977 routines to optimize the code.
3979 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Replaced the client entry's `channel' list and channel entry's
3982 `user_list' list to hash tables for optimized lookup. Changed
3983 the code to use the hash table interface around the code.
3984 Affected file lib/silcd/idlist.[ch].
3986 * Added `auto_rehash' boolean argument to the function
3987 silc_hash_table_alloc to indicate whether the hash table should
3988 auto-rehash when it thinks is appropriate time. It will
3989 increase the hash table size if the there is twice as much
3990 entries in the table than the size of the table, and will
3991 decrease the size if there are twice as less entries than
3992 the size of the table.
3994 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3998 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * silc_idcache_purge_by_context deletes the entry now by context
4001 as it is supposed to do. Affected file lib/silccore/idcache.c.
4003 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4004 client is not anymore valid (WHOWAS givens the info) and not
4005 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4007 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Removed the `data' and `data_len' arguments from the ID Cache
4010 interfaces and added `name' argument. ID Cache does not handle
4011 anymore the binary data only a names associated with given ID.
4013 * When hashing a Client ID with silc_hash_id the entire ID is
4014 not hashed anymore, instead only the hash of the Client ID is
4015 hashed. This way we can access the Client ID from the cache
4016 with Client ID but with the hash of the ID (which is a hash of
4017 the nickname) as well without any difference in performance.
4019 Added also silc_idcache_find_by_id_one_ext to do one on one
4020 searching when we have the actual ID. Added also function
4021 silc_hash_client_id_compare. The affected files are
4022 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4024 * When hashing the name associated with a ID it is always done
4025 in lowercase. This way we can access the cache without worrying
4026 about case-sensitivity, even though, for example nicknames are
4029 * Fixed a bug in server with channel message sending. It put
4030 wrong ID type as destination ID. The affected file
4031 silcd/packet_send.c.
4033 * silc_idcache_del_by_context now deletes from all hash tables
4034 by context. Affected file lib/silccore/idcache.c.
4036 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Changed the client library to use the new ID Cache interface.
4039 Changes around the source tree.
4041 * Added silc_hash_table_rehash_ext to rehash with specific
4042 hash function. Affected file lib/silcutil/silchashtable.[ch].
4044 * Added silc_hash_string_compare to compare two strings in the
4045 hash table. Affected file lib/silcutil/silcutil.[ch].
4047 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4049 * Added new function silc_idcache_del_by_context into the
4050 lib/silccore/idcache.[ch].
4052 * Changed the server's ID list routines to use the new ID Cache
4053 interface. Changes around the source tree.
4055 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4057 * Added silc_hash_table_del[_by_context]_ext functions in to the
4058 lib/silcutil/silchashtable.[ch].
4060 Removed silc_hash_table_find_all* routines and added new
4061 silc_hash_table_find_foreach to replace them.
4063 Added silc_hash_table_replace_ext function as extended
4064 replacing function. Separated the simple hash table interface
4065 from the extended hash table interface in the file
4066 lib/silcutil/silchashtable.h.
4068 * Fixed minor bugs and changed it to use some of the new
4069 hash table functions in lib/silccore/idcache.c
4071 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Added new function silc_hash_table_find_all to return all keys
4074 in the hash table by the specified key. As the hash table is
4075 collision resistant it also makes it possible to have several
4076 duplicate keys in the hash table. This function may be used to
4077 find all of the keys from the hash.
4079 Added user_context arguments to the SilcHashFunction,
4080 SilcHashCompare and SilcHashDestructor to deliver user specified
4083 Added new fuctions silc_hash_table_find[_all]_ext to do
4084 extended lookup with specified hash and compare functions and
4085 specified user contexts.
4087 Added new function silc_hash_table_add_ext to add the key
4088 with specified hash function and user context.
4090 Added new function silc_hash_table_foreach to traverse all
4091 entrys in the hash table. Added SilcHashForeach callback
4094 Added new function silc_hash_table_del_by_context to delete
4095 the entry only if the context associated with the key matches.
4097 Affected files are lib/silcutil/silchashtable.[ch].
4099 * Removed silc_hash_[server/client/channel]_id and added just
4100 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4101 silc_hash_id_compare to compare two ID's using as the hash table
4102 comparison function. Added also silc_hash_data to hash
4103 binary data and silc_hash_data_compare to compare it.
4105 * Removed silc_idlist_find_client_by_hash as it is not needed
4106 anymore. Affected file silcd/idlist.[ch].
4108 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4109 to use internally the SilcHashTable. The new ID Cache is a lot
4110 faster than the old one. Some of the ID Cache interface was also
4111 rewritten and obsolete and stupid functions were removed.
4113 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Added entry_count field to the SilcHashTable to keep the number
4116 of the entries in the table. Implemented the function
4117 silc_hash_table_rehash. Added new function
4118 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4120 Fixed a minor bug in silc_hash_table_free.
4122 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4123 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4124 into the lib/silcutil/silcutil.[ch].
4126 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Implemented a collision resistant hash table into the
4129 lib/silcutil/silchashtable[ch]. See the header and the source
4130 for the SilcHashTable API.
4132 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Merged dotconf version 1.0.2 into lib/dotconf.
4136 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Do not compile anything in lib/silcsim/* if the SIM support
4139 is not enabled. The tree should now compile without problems
4142 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Compiled the SILC under cygwin. Compiled and tested briefly
4145 without problems. More tests needed. The SIMs didn't compile
4148 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4150 * Fixed possible crash in silc_get_username in the
4151 lib/silcutil/silcutil.c.
4153 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Fixed a va_arg in silc/client_ops.c.
4157 * Oops, RC5 routines were named AES and caused some problems
4158 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4160 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4162 * Added new SilcIDIP structure into the lib/silccore/id.h and
4163 replaced the old `ip' fields from all SILC ID's to that type.
4164 This is a step towards IPv6 support.
4166 The silc_id_get_len takes now the ID as an extra argument.
4167 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4168 both IPv4 and IPv6 based ID's.
4170 The affected files are lib/silccore/id.[ch] and other files
4171 around the tree using these routines.
4173 * Removed the ID length arguments in server from various
4174 silc_server_send_notify_* routines -> they are not needed
4177 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4179 * Fixed memory leak in silc_encode_pem_file in the file
4180 lib/silcutil/silcutil.c.
4182 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Check minor version as well in the SKE. Affected files are
4185 silcd/protocol.c and lib/silcclient/protocol.c.
4187 * Added --identifier option to the server so that an identifier
4188 can be when creating the public key for the server. Affected
4189 file is silcd/silcd.c.
4191 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4192 lib/silccrypt/silcpkcs.c.
4194 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Register default ciphers and stuff when using -C option with
4197 the server. Affected file sildc/silcd.c.
4199 * Put back the servers public key filename format, it is better
4200 than the new one. For now, the client keys are saved with the
4201 new filename format. The affected file silc/client_ops.c.
4203 * Implemented the Cipher API for the rest of the ciphers that
4204 did not implement it or implemented it the wrong way.
4206 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Register default ciphers and stuff when using the -S option
4209 in the client. Affected file silc/silc.c. Same also when
4210 creating new key pair with -C option.
4212 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Fixed the silc_verify_public_key client operation function to
4215 save the public keys differently. The fingerprint is now
4216 used as filename and not the hostname. This way also the
4217 client keys are saved uniquely and not with hostnames. The
4218 affected file is silc/client_ops.c.
4220 * Trimmed the silc_hash_fingerprint function to remove extra
4221 whitespaces from the end of the fingerprint. The affected
4222 file is lib/silccrypt/silchash.c.
4226 * Added silc_cipher_register_default function to register all
4227 default ciphers. It can be used when configuration files
4228 does not exist and the application does not want any specific
4229 ciphers in any specific order.
4231 The SilcDList is now used as silc_cipher_list dynamically
4232 allocated cipher list. Removed the static list all together
4233 and now all ciphers must be allocated to the dynamic list.
4234 The silc_cipher_alloc routine was changed to check only the
4237 All silc_cipher_* routines that used to return int returns
4240 The affected files lib/silccrypt/silccrypt.[ch].
4242 * The same thing was done to silc_hash_* as for silc_cipher_*
4243 routines. Affected files lib/silccrypt/silchash.[ch].
4245 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4246 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4247 Added also silc_pkcs_[un]register[_default] functions.
4248 Removed the data_context from the PKCS API.
4250 * Added silc_hmac_register_default function to register default
4251 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4252 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4253 to unregister all hmacs at once.
4255 * Register the default ciphers, hash functions, PKCSs and HMACs
4256 if client's configuration file does not exist. The affected
4259 * The client did not load the hash functions from the SIM
4260 modules at all. Added support for this. Affected file is
4261 silc/clientconfig.c.
4263 * When decoding public key with silc_pkcs_public_key_decode, check
4264 the supported algorithm only if PKCS are registered. Affected
4265 file lib/silccrypt/silcpkcs.c. The same was done with the
4266 silc_pkcs_private_key_decode.
4268 * Fixed the SILC List routines to keep the list always in order.
4269 It used to change the list's order when traversing the list but
4270 not it preserves the order. Affected file lib/trq/silclist.h.
4272 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Added the client library to use the SilcSocketConnection's
4275 reference counter (by silc_socket_dup) to prevent the bug that
4276 the socket object may be freed underneath async operation.
4278 * The name resolv library checking fixes in the configure.in.pre.
4281 * Created new version of the protocol drafts for future
4282 development. The -03 drafts are the ones that will be changed
4283 in the trunk now and the -02 will remain as they are.
4285 * Send list of CUMODE notifys to the router when announcing
4286 the channel users to the router. Affected file silcd/server.c.
4287 If the router receiving channel founder CUMODE for a channel
4288 that already has channel founder it will send CUMODE notify
4289 to the sender to remove the channel founder rights from the
4290 announced client. Affected file silcd/packet_receive.c.
4292 * The CUMODE notify may now use Server ID as well as the entity
4293 who changes the mode. Updated protocool specs.
4295 * Updated INSTALL and README files.
4297 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * New web pages in the http://silc.pspt.fi. The pages was
4304 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4306 * Implemented the [DenyConnectin] config section in the server.
4307 Added silc_server_config_denied_conn to check whether incoming
4308 connection is denied. Affected file silcd/serverconfig.[ch].
4310 * Do not check the ports when checking the incoming configuration
4311 data if the port is 0, meaning any. Affected file is
4312 silcd/serverconfig.c.
4314 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Fixed buffer overflow in silc_string_compare in the file
4317 lib/silcutil/silcutil.c.
4319 * Fixed double free in silc_server_command_leave in the file
4322 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Fixed the version checking in the server. Affected file is
4327 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Fixed the configuration data fetching when accepting new
4330 connections in the server. Affected file silcd/server.c.
4332 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Added `sender_entry' argument to the function
4335 silc_server_packet_relay_to_channel so that we can check
4336 whether some destination actually belongs to the same route
4337 the sender belongs (ie, we must not resend the packet to the
4338 sender). Affected file silcd/packet_send.[ch].
4340 * Added `servername' field to the SilcClientEntry in the server
4341 to hold the name of the server where client is from. Affected
4342 file is silcd/idlist.h.
4344 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Moved the channel message encrypting in the router betwen
4347 router connections from silc_server_channel_message to the
4348 silc_server_packet_relay_to_channel since we want to check
4349 whether we have anybody channel before encrypting anything.
4350 Affected files silcd/packet_[receive/send].c.
4352 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Fixed the [AdminConnection] server config section to support
4355 multiple entries. Affected file silcd/serverconfig.c.
4357 * Added support into the server to check the validity of the
4358 incoming connection before executing any KE or authentication
4361 * The connection configuration is now saved to the KE and
4362 connection auth protocol contexts and not fetched anymore in
4363 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4365 * The local hosts listenning address and port is also resolved
4366 now when starting the server. We want to have the socket object
4367 to include the real address and port for the listener. Added
4368 new function silc_net_check_local_by_sock into the files
4369 lib/silcutil/silcnet.[ch].
4371 * Fixed a broadcast bug in server -> do not broadcast if we
4374 * Fixed a routing bug. Do not route broadcast packets ever.
4375 Broadcast packets must be processed always and not routed since
4376 they may be destined to some other host than yourself and thus
4377 would get routed without no good reason. Affected file is
4380 * Added function silc_server_config_is_primary_route to check
4381 whether primary router connection has been configured (a router
4382 configuration that we are initiating). If there is not, we
4383 will assume that there is only two routers in the SILC network
4384 and we will use the incoming router connection as our primary
4385 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4387 * Changed the order of the broadcasting. Broadcast _after_ the
4388 packet has been processed not before. Affected file is
4391 * Fixed a [ClientConnection] parsing bug. The port was never
4392 parsed correctly thus resulting to port 0. Affected file
4393 silcd/serverconfig.c.
4395 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4396 argument and did not set the broadcast packet flag. Affected
4397 file silcd/packet_send.c. Fixed same bug in the function
4398 silc_server_send_notify as well.
4400 * If we receive NEW_ID packet for our own ID in the server, ignore
4403 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Removed the nickname from the Private Message Payload.
4408 Updated the code and the protocol specs.
4410 * Updated protocol specs for submitting to the IETF.
4412 * Tweaked the Random Number Generator a bit. Affected file
4413 lib/silccrypt/silcrng.c. Exported a new function
4414 silc_rng_[global]_add_noise which can be used to add more
4417 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Do not parse packets with different timeout when protocol
4420 is active -> may cause problem with rekey. Affected file
4423 * When server receives signoff notify it must not create
4424 new channel key if the client is on any channels since the
4425 sender of the signoff notify will create it.
4427 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added printing of error messages during SKE protocol from the
4430 failure packet sent by server during SKE. Affected file
4433 * Removed the client's failure_callback handling with timeout
4434 and handle it immediately when received.
4436 * The SKE library returned wrong type in SUCCESS and FAILURE
4437 packets. They must be 32 bit MSB not 16 bit MSB.
4439 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Ok, rewrote the logic of the re-key and now it seems to work.
4442 I tested it on high traffic with frequent re-keys without
4443 problems. Added hmac_receive (and renamed hmac to hmac_send)
4444 in SilcClientConnection in lib/silcclient/client.h and
4445 in SilcIDListData in silcd/idlist.h. Also, removed the
4446 SilcPacketParserContext's cipher and hmac fields as they are
4447 not needed anymore and actually caused some problems when
4448 the ciphers and hmac's changed underneath the packet parser.
4450 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * If re-key protocol is active then process the incoming packets
4453 synchronously since we must assure that icoming packets encrypted
4454 with the old key is processed before the new keys is set to
4455 use. This is true other packets than for REKEY packets.
4456 Affected file silcd/server.c. The same was done to client library
4457 as well, affected file lib/silcclient/client.c.
4459 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Fixed bug in client and server to accept the force send if
4462 the packet is send from silc_[server/client]_packet_process
4463 function. Otherwise the packets are never delivered, oops.
4465 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4467 * Disable force sending of packets when REKEY protocol is active.
4468 We must assure that no packet is sent directly when rekey is
4469 performed. All packets must be sent through packet queue.
4470 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4471 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4472 function is silc_[server/client]_packet_send_real to check
4475 * Replaced the SIM paths from example config files to
4476 /usr/local/modules. Also, make install creates now
4477 /usr/local/silc/logs directory to hold all the SILC server
4480 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * Made the configure.in.pre work on Solaris. Patch by salo.
4484 * Made all ciphers compatible with non-x86 machines. Defined
4485 CBC mode macros into lib/silccrypt/ciphers_def.h.
4487 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Fixed the make install.
4491 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * When MAC computation fails the silc_packet_decrypt returned 0
4494 even though it was supposed to return -1. Fixed this. The
4495 affected file is lib/silccore/silcpacket.c.
4497 * Do not replace the config files in /etc/silc (in make install)
4498 if they already exist. Affected file ./Makefile.am.
4500 * Do not send re-key packets immediately but through packet queue.
4501 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4503 * Changed silc_net_check_host_by_sock to return FALSE if the
4504 IP/DNS could not be resolved. Though, it returns the IP address
4505 now even if it could not resolve it (but returns also FALSE).
4506 Affected file lib/silcutil/silcnet.[ch].
4508 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Added silc_pkcs_decode_identifier to decode the public key's
4511 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4512 Added also silc_pkcs_free_identifier. Added also new context
4513 SilcPublicKeyIdentifier.
4515 * Added -S option to the silc client. It is used to dump the
4516 contents of the specified public key file.
4518 * Changed the PKCS api to return the public key length when
4519 setting the public key.
4521 * Fixed a fatal bug in the public and private key file loading.
4522 Affected file lib/silccrypt/silcpkcs.c.
4524 * Execute the packet parsing for client with zero (0) timeout
4525 if the protocol is active. Affected file silcd/server.c.
4527 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Made the key generation options to the silcd program. Added
4530 -C option, equivalent to client's option.
4532 * Added new [ServerKeys] config section to the server. It
4533 configures the server's public and private key.
4535 * Defined generic Public Key Payload into the protocol
4536 specification to send specific type of public keys and
4539 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4540 public key or certificate.
4542 * Implemented the GETKEY command to the server and to the
4543 client library and on user interface.
4545 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Made preliminary `make install' work.
4549 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Added SilcServerRekey context into silcd/idlist.h.
4553 * Added the PFS support as defined in the specification to the
4554 SKE protocol. Affected files lib/silcske/*.c.
4556 * Added `ske_group' field to the SilcServerRekey context to hold
4557 the number of the SKE group that is used with PFS in re-key.
4558 Affected file silcd/idlist.h.
4560 * Added PFS re-key support to the server. Affected file is
4563 * Added silc_protocol_cancel to cancel execution of the next
4564 state of the protocol. Affected file is
4565 lib/silccore/silcprotocol.[ch].
4567 * Added the re-key support with and without PFS to the client
4568 library. Re-key is performed once in an hour, by default.
4570 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4571 Added silc_client_rekey_callback and silc_client_rekey_final.
4572 Affected files are lib/silcclient/protocol.[ch] and
4573 lib/silcclient/client.[ch].
4575 * Removed the `hmac_key' and `hmac_key_len' fields from the
4576 SilcClientConnection structure; not needed. Affected file is
4577 lib/silcclient/client.h.
4581 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Do not ask whether user wants to use the negotiated private key
4584 for private messages, just use it. Affected file is
4585 silc/local_command.c.
4587 * Added `send_enc_key' and `enc_key_len' fields to the
4588 SilcIDListData structure since they are needed in the re-key
4589 phase. Affected file is silcd/idlist.[ch].
4591 * Implemented the simple re-key protocol into the server.
4592 Affected files silcd/server.c and silcd/protocol.[ch]. The
4593 re-key will be performed once in an hour, by default.
4595 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4596 Added silc_server_rekey, silc_server_rekey_callback and
4597 silc_server_rekey_final.
4599 * Removed Tunneled flag from the protocol. Updated the code
4600 and the specifications.
4602 * Adde `pfs' field to the SilcIDListData to indicate whether
4603 the PFS is to be performed in the re-key. Affected file is
4606 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4609 int64 of at least the xintXX size. If void * is less that 4
4610 bytes uint32 * will be used. Defined bool as boolean.
4612 * Changed _ALL_ unsigned long and unsigned int to uint32,
4613 unsgined short to uint16 in the source tree.
4615 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4616 not handle clients that has entry->data.registered == FALSE.
4617 They are not in the network anymore. Affected file is
4620 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Implemented the sending of the SERVER_SIGNOFF notify in the
4623 server. Affected file is silcd/server.c.
4625 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4626 Added also silc_notify_payload_encode_args into the
4627 lib/silccore/silcnotify.[ch].
4629 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4630 Affected file silcd/packet_receive.c.
4632 * Implemented the SERVER_SIGNOFF notify handling in the client
4633 library. Affected file lib/silcclient/client_notify.c. Also,
4634 implemnted the printing of the SERVER_SIGNOFF info to the
4635 application. Affected file silc/client_ops.c.
4637 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4638 if the deleting was successful. Affected file silcd/idlist.[ch].
4640 * Added support for public key authentication in the connection
4641 authentication protocol in the client library. Affected file
4642 lib/silcclient/protocol.c.
4644 * Changed the server's silc_idlist_get_clients_by_* interface
4645 to support already allocated array so that new entries may be
4646 added to pre-allocated array. Affected file silcd/idlist.[ch].
4647 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4648 and command replies.
4650 * All command reply functions in the server now calls the
4651 pending command callback even if error occured. This way the
4652 error will be delivered to the client as well. Affected files
4653 silcd/command.c and silcd/command_reply.c.
4655 * Fixed INFO command to return local server's info if no server
4656 was provided. Affected file lib/silcclient/command.c.
4658 * Removed RESTART command for good. Updated the code and the
4661 * Rewrote parts of the task system. It is a bit simpler now.
4662 Removed unsued task priorities. The affected files are
4663 lib/silcutil/silctask.[ch].
4665 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Moved the USERS printing from the library to the application.
4668 Affected files lib/silcclient/command.c and silc/client_ops.c.
4670 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Added channel key re-key support. The re-key is perfomed
4675 only by the router and is done once in an hour. Added `rekey'
4676 field to the SilcChannelEntry in the server. Affected files
4677 silcd/server.c and silcd/idlist.h.
4679 * Added silc_task_unregister_by_context into the file
4680 lib/silcutil/silctask.[ch].
4682 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Added SILC_UMODE_GONE mode to indicate when the client is not
4685 present in the SILC network. Added also support to the local
4686 command AWAY that will set this mode. Added support of showing
4687 "xxx is gone" in WHOIS command. The USERS command shows the
4688 gone status as well.
4690 * Fixed setting server and router operator privileges in the
4691 server's UMODE command. Affected file silcd/command.c.
4693 * Merged the SKE KE1 and KE2 payloads into one payload. The
4694 new KE payload is equivalent to the old KE2 payload.
4696 Cleaned up the SKE Start Payload parsing. It now uses the
4697 simple buffer unformatting to do the parsing. A lot faster
4700 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4701 to the SKE that is used to indicate whether both of the SKE
4702 parties should perform authentication. By default only the
4703 responder performs authentication. By setting this flag also
4704 the initiator must do authentication. By default it is unset
4705 since in normal SKE case, client to server connection, only
4706 the responder should do authentication. When doing SKE between
4707 two clients both should perform authentication. Updated the
4708 code and the protocol specs.
4710 * A little fix to IDENTIFY command in the server. Search the
4711 client first by hash not nickname. Affected file is
4714 * Fixed the silc_client_close_connection to support closing
4715 the client to client connections wihtout deleting too much
4716 data. Affected file lib/silcclient/client.c.
4718 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4719 are received if protocol used to be active but is not anymore
4720 the application would crash due to NULL pointer dereference.
4721 Affected files silcd/server.c and lib/silcclient/client.c.
4723 * Added `hash' field to the SilcClientConnection to include
4724 the hash function negotiated in the SKE protocol.
4726 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4727 to set the channel founder authentication data. A client can
4728 claim the founder rights later by providing the authentication
4729 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4730 This way the channel founder can regain the channel founder
4731 privileges even it is left the channel. This works only on
4732 local server and the client must be connected to the same
4733 server to be able to regain the founder rights. Updated the
4734 protocol specs accordingly.
4736 Added support to the CMODE command in the client to set the
4737 founder auth data. Read the README to see how to set it.
4739 Added support to the CUMODE command to claim the founder
4740 rights. Read the README to see how to do it.
4742 Added support for the founder authentication to the Channel
4743 Entry in the server. Affected file silcd/idlist.h.
4745 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4746 server's CMODE command. Affected file silcd/command.c.
4748 * Added the following new functions into lib/silccore/silcauth.[ch]:
4749 silc_auth_get_method and silc_auth_get_data.
4751 * The server now saves the remote hosts public key to the
4752 SilcIDListData pointer. Affected file silcd/protocol.c.
4754 * The normal server now does not remove the channel entry from
4755 the cache if the founder authentication data is set. It used
4756 to remove it if the founder was the last one on the channel on
4757 the server and left the channel. The auth data is saved and
4758 if the channel is re-joined later the old entry is used with
4759 the old auth data. Affected files silcd/command_reply.c and
4762 * Removed the `pkcs' field from the SilcIDListData structure
4763 in the server; it is not used. Affected file silcd/idlist.h.
4765 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Fixed packet processing on slow links. Partial packets were
4768 never re-processed because the incoming data buffer was cleared
4769 by the application. Application must not directly clear the
4770 sock->inbuf, the packet processing routines handle it. Fixed
4771 this in client library and in server.
4773 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Fixed the WHOIS and IDENTIFY send reply function to really
4776 check whether to send list or just one entry. Affected file
4779 * Cleaned up the LEAVE command's channel key distribution. The
4780 affected file silcd/command.c.
4782 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4783 can enforce the channel mode as well. In that case the ID
4784 includes the ID of the server. The code now enforces the
4785 mode change if the router have different mode than the server.
4787 * The notify client operation with CMODE_CHANGE notify can now
4788 return NULL client_entry pointer if the CMODE was not changed
4789 by client. Application must check for this.
4791 * Added <Server ID> argument to INFO command to support server
4792 info fetching by Server ID.
4794 * Added silc_server_announce_get_channel_users to get assembled
4795 packets of channel users of the specified channel. Affected
4796 file silcd/server.[ch].
4798 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4799 was freed underneath the ID Cache.
4801 * Re-announce clients when the server received CHANNEL_CHANGE
4802 notify from the router. Affected file silcd/packet_send.c.
4804 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4807 crashed since it did not handle the fact that there is no cipher
4808 called "3" and didn't check the error condition. Now fixed.
4810 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4811 flag. It can be used to send message requests.
4813 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Implemented the RESTART command in the client.
4817 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4818 notice type messages. Added notice printing to the user
4821 * The channel keys are not re-generated if the channel's mode
4822 is PRIVKEY, ie private key on the channel exists. Affected
4823 files silcd/server.c and silcd/command.c.
4825 * Fixed a little bug in channel message delivery when channel
4826 private keys are set in the server. Affected file is
4827 silcd/packet_send.c.
4829 * Changed the setting on channel->on_channel = TRUE from the
4830 silc_client_save_channel_key to the JOIN command reply. The
4831 key payload is not received if the private channel key is set.
4832 Affected file lib/silcclient/command_reply.c and the
4833 lib/silcclient/client_channel.c.
4835 * When the CMODE_CHANGE notify is sent and the channel private
4836 key mode is removed the channel key must be re-generated in
4837 other cells as well. Added this support for the router in the
4838 silcd/packet_receive.c.
4840 * Added new local command NOTICE to send notice message on
4841 channel. Affected file silc/local_command.[ch].
4843 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Added new local command ME to the client. It is used to send
4846 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4847 some action. Affected file silc/local_command.[ch].
4849 * Changed channel_message and private_message client operations
4850 to deliver the message flags to the application. Added also
4851 the `flags' arguments to the silc_client_send_channel_message
4852 and silc_client_send_private_message functions. Affected file
4855 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Redefined the Private Message Payload to support private message
4858 keys and to support the new private message flags. Updated
4859 the protocol specs. Flags makes it possible to have for example
4860 CTCP style messages.
4862 * Added new type SilcPrivateMessagePayload and defined an API
4863 for it in the lib/silcclient/silcprivate.[ch].
4865 * Tested private message private keys successfully. Tested the
4866 private message key set, unset and list commands with the new
4869 * Redefined the Channel Message Payload to include the channel
4870 message flags (equal with private message flags) to support
4871 for example CTCP style messages.
4873 * Defined some of the message (for channel and private message)
4874 flags. Updated the protocol specs and added the flags to the
4875 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4877 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added SilcKeyAgreementStatus type to the key agreement routines
4880 to indicate the current status and error if one occured.
4881 The status types are defined in the lib/silcclient/silcapi.h.
4883 * Added new local command KEY that is used to set and unset private
4884 keys for channels, set and unset private keys for private messages
4885 with remote clients and to send key agreement requests and
4886 negotiate the key agreement protocol with remote client. The
4887 key agreement is supported only to negotiate private message keys,
4888 it currently cannot be used to negotiate private keys for channels,
4889 as it is not convenient for that purpose.
4891 * Fixed a minor pending callback setting bug in the function
4892 silc_client_get_client_by_id_resolve, now the function works.
4893 Affected file lib/silcclient/idlist.c.
4895 * Added function silc_net_get_local_port to get local bound
4896 port by socket. Added to lib/silcutil/silcnet.[ch].
4898 * Added `sockets' and `sockets_count' fields to the SilcClient
4899 object. They hold the sockets of the listenning sockets in
4900 the client. Listenning sockets may be for example the key
4901 agreement server. Affected file lib/silcclient/client.[ch].
4902 Added functions the silc_client_add_socket and the
4903 silc_client_del_socket. They are exported to the application
4906 * Added ~./silc/clientkeys to support other client's public keys.
4908 * Renamed verify_server_key client operation to verify_public_key
4909 and added one argument to indicate the type of the connection
4910 (server, client etc.).
4912 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Added silc_server_connection_auth_request to handle the
4915 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4916 silcd/packet_receive.[ch].
4918 * Added silc_server_send_connection_auth_request into the
4919 silcd/packet_send.c to send the connection auth request packet.
4921 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4924 * Fixed the public key authentication in responder side in the
4925 server. The `auth_data' pointer includes the SilcPublicKey
4926 not the path to the public key. Affected file silcd/protocol.c.
4928 * Implemented the public key authentication in the initiator side
4929 in the server. Affected file silcd/protocol.c.
4931 * Removed the [RedirectClient] config section from the server
4932 configuration. Is not needed and I don't want to implement it.
4934 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4936 * Cleaned up the CMODE command in the server. It now works
4937 correctly and supports all the modes defined in the protocol.
4938 Affected file is silcd/command.c.
4940 * Added `hmac_name' field to the SilcChannelEntry in the server
4941 to hold the default HMAC of the channel. It can be set when
4942 creating the channel (with JOIN command). Affected files
4945 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4946 type to indicate the change of the current cipher and hmac
4947 on the channel. Client can safely ignore the <cipher> argument
4948 (if it chooses to do so) since the CHANNEL_KEY packet will
4949 force the channel key change anyway. The <hmac> argument is
4950 important since the client is responsible of setting the new
4951 HMAC and the hmac key into use.
4953 * Fixed the CMODE command in the client library as well.
4955 * Tested CMODE command in router environment successfully.
4957 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Show the version of the remote client (or server) when connecting
4960 to the server. It is logged to the log file. Affected file
4961 is silcd/protocol.c.
4963 * Fixed the KILLED notify handling in the client library. The
4964 client must be removed from all channels when receiving the
4967 Also, do not remove the client entry when giving the KILL
4968 command but when the KILLED notify is received.
4970 * Removed silc_idlist_find_client_by_nickname from the server.
4971 Not needed anymore. Affected files silcd/idlist.[ch].
4973 * Implemented the CHANNEL_CHANGE notify type handling to the
4974 server. Affected file silcd/server.c.
4978 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added silc_server_send_notify_invite to send the INVITE
4981 notify between routers.
4983 * Implemented the INVITE command correctly to the server.
4985 * Implemented the INVITE notify type handling in the server.
4987 * Implemented the INVITE command to the client library and on the
4990 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added function silc_server_get_client_resolve to find the
4993 client entry by ID from all ID lists and then resolve it
4994 (using WHOIS) if it cannot be found. Affected file is
4997 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4999 * Implemented the BAN command to the client library.
5001 * The JOIN command in the server now checks the invite list
5004 * Changed the silc_command_reply_payload_encode_va and the
5005 silc_command_payload_encode_va to support that if argument is
5006 NULL it ignores and checks the next argument. Affected file
5007 lib/silccore/silccommand.c.
5009 * Added silc_server_send_notify_ban to send the BAN notify
5010 type between routers.
5012 * Chaned the silc_notify_payload_encode to support that if
5013 argument is NULL it ignores and checks the next argument.
5014 Affected file lib/silccore/silcnotify.c.
5016 * Tested ban lists in router environment successfully.
5018 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Implemented BAN command to the server, in silcd/command.[ch].
5022 * Removed the BAN and INVITE_LIST modes from the CMODE command
5025 * Added function silc_string_match to regex match two strings.
5026 Affected files lib/silcutil/silcutil.[ch].
5028 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Redefined parts of the SilcChannelEntry in the server to support
5031 the new ban and invite lists.
5033 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Redefined the INVITE command. The same command can be used to
5036 invite individuals to the channel but also to manage the invite
5037 list of the channel (to add to and remove from the invite list).
5038 Updated the protocol specs.
5040 * Added new command SILC_COMMAND_BAN that can be used to manage
5041 the ban list of the channel. Updated the protocol specs.
5043 * Removed the channel modes: the SILC_CMODE_BAN and the
5044 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5045 in the CMODE command. The equivalent features are now available
5046 using INVITE and BAN commands. Updated the protocol specs.
5048 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5049 in the network about change in the current ban list. The notify
5050 type is not used by the client.
5052 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5053 support the invite lists.
5055 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Added new function silc_string_regexify that converts string
5058 including wildcard characters into regex string that can
5059 be used by the GNU regex library. Added into the file
5060 lib/silcutil/silcutil.[ch].
5062 Added silc_string_regex_combine to combine to regex strings
5063 into one so that they can be used as one regex string by
5064 the GNU regex library. Added into the file
5065 lib/silcutil/silcutil.[ch].
5067 Added silc_string_regex_match to match two strings. It returns
5068 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5070 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Imported GNU regex to the soruce tree into lib/contrib.
5073 Fixed some compiler warning from the regex.c.
5075 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Fixed MOTD command in the server to work in router environment.
5079 * Fixed the MOTD command in the client library to support
5080 the server argument in the command.
5082 * Added `nickname_len' argument to the silc_idlist_add_client
5083 in the server, as the `nickname' argument may be binary data
5086 * Added silc_idlist_get_channels to return all channels from
5089 * Implemented LIST command to the server. Affected file is
5092 * Implemented the LIST command to the client library and on the
5095 * Added [<user count>] argument to the LIST command reply.
5096 With private channels the user count is not shown.
5098 * Updated TODO and README.
5100 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * The client entry's data.registered must be TRUE even with
5103 global client entry on global client list. The data.registered
5104 is used to check whether the client is anymore in the network,
5105 for example with WHOWAS command so it must be valid.
5107 * Fixed the WHOWAS command in the server. It now actually works
5108 in router environment. Added function into silcd/command_reply.c
5109 silc_server_command_reply_whowas_save.
5111 * Added silc_idlist_purge function to the silcd/idlist.c
5112 to periodically purge the ID Cache.
5114 * Fixed INFO command in the server. It works now in router
5115 environment. Added <server name> argument to the INFO command
5116 reply. Updated the protocol specs.
5118 * Fixed minor bug in silc_idcache_purge to not purge if the
5119 expire value is zero.
5121 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5122 they were buggy because of the WHOWAS information.
5124 * Fixed local command MSG to handle the async resolving of
5125 the remote client properly. It used to fail the first MSG.
5126 Affected file silc/local_command.c.
5128 * Added `data_len' field to SilcIDCache context.
5130 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Update TODO. Todo in commands in the server.
5134 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5137 used by routers as broadcast packet to inform other routers
5138 about the changed user mode.
5140 Implemented the notify handling in the server. Affected file is
5141 silcd/packet_receive.c. Added the function
5142 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5144 * Added new generic Channel Payload and deprecated the New Channel
5145 Payload. The New Channel Payload is now the generic Channel
5148 * Added new argument `mode' to the silc_server_send_new_channel
5149 as it is required in the Channel Payload now.
5151 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5152 and created a new and real SilChannelPayload to represent the
5153 new generic Channel Payload. Implemented the encode/decode
5154 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5156 * Added silc_server_get_client_channel_list to return the list
5157 of channels the client has joined for WHOIS command reply.
5158 Affected file silcd/server.[ch].
5160 * Implemented the channel list sending in the WHOIS command reply
5161 in server and in the client.
5163 Implemented the channel list displaying on the user interface
5164 as well. Affected file silc/client_ops.c.
5166 * Added silc_channel_payload_parse_list to parse list of Channel
5167 Payloads. It returns SilcDList list of SilcChannelPayloads.
5168 Client for example can use this function to parse the list of
5169 channels it receives in the WHOIS command reply. The caller
5170 must free the list by calling silc_channel_payload_list_free.
5171 Affected files lib/silccore/silcchannel.[ch].
5173 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Added one new argument <user mode> to the WHOIS command reply
5176 to return the mode of the user in SILC. Updated the protocol
5179 Implemented it to the server and client.
5181 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Fixed the mode printing on the user interface on joining.
5184 Affected file silc/client_ops.c.
5186 * Implemented the UMODE command and user modes in general to the
5187 client library and to the user interface.
5189 * Implemented the UMODE command to the server.
5191 * The server now sends UNKNOWN_COMMAND error status if client sends
5192 unknown command. Affected file silcd/command.c.
5194 * All server commands now handle the command identifier the right
5195 way when sending the command reply to the client. The client can
5196 use to identify the command replies with the identifier.
5198 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Added silc_server_get_client_route to resolve the route to
5201 the client indicated by the client ID. Affected file is
5204 * Added silc_server_relay_packet as general function to relay
5205 packet to arbitrary destination. This deprecates functions
5206 like _send_private_message_key, _relay_notify etc. Affected
5207 file is silcd/packet_send.[ch].
5209 Removed silc_server_send_key_agreement,
5210 silc_server_send_private_message_key and
5211 silc_server_packet_relay_notify functions from the file
5212 silcd/packet_send.[ch].
5216 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5217 server. Affected file silcd/packet_receive.[ch].
5219 * Implemented the KILL command to the client. Implemented the
5220 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5221 Affected files lib/silcclient/command[_reply].c and
5222 lib/silcclient/client_notify.c. Implemented the KILL notify
5223 printing in the user inteface.
5225 * Fixed a lot silc_parse_nick memory leaks from the client
5226 library in the file lib/silcclient/command.c.
5228 * Changed the silc_server_send_notify_on_channels's `sender'
5229 argument from SilcSocketConnection to SilcClientEntry to
5230 check the sender as entry and not as connection object and not
5231 to send to the client provided as argument. The affected file
5232 is silcd/packet_send.[ch].
5234 * The notify packets that are destined directly to the client used
5235 to not to be processed by the server. Now changed that and the
5236 server processes all notify packets. After relaying the packet
5237 to the client the notify packet is processed in the server.
5239 * The silc_server_free_client_data now checks whether there is
5240 pending outgoing traffic for the client and purges the data to
5241 the network before removing the client entry.
5243 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5246 an client is killed from the SILC Network. Updated the protocol
5249 Added new function silc_server_send_notify_killed to the
5250 silcd/packet_send.[ch].
5252 * Added function silc_server_packet_relay_notify to relay notify
5253 packets that are destined directly to a client. In this case
5254 the server does not process the notify packets but merely relays
5255 it to the client. Affected file silcd/packet_send.[ch].
5257 Added also silc_server_packet_process_relay_notify to check
5258 whereto relay the notify. Affected file is
5259 silcd/packet_receive.[ch].
5261 * Implemented the KILL command to the server.
5265 * Added the backup schema desgined last fall to the protocol
5266 specs for everyone to see. The specification is in the
5267 *-spec-xx.txt draft and the packet type definitions for the
5268 backup routers is in *-pp-xx.txt draft. Thusly, added also
5269 new packet type SILC_PACKET_CELL_ROUTERS.
5271 * A big security problem in the implementation discovered. The
5272 signoff of an client did not cause new channel key generation
5273 which it of course should've done. The channel keys must be
5274 always re-generated when client leaves (or signoffs) the channel.
5275 The silc_server_remove_from_channels funtion now handles
5276 the channel key re-generation.
5278 * Added `sender' argument to the silc_server_send_notify_on_channels
5279 to not to send the client provided as argument. Affected file
5280 silcd/packet_send.[ch].
5282 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5284 * Implemented OPER and SILCOPER commands into the server and
5287 * Added silc_auth_verify and silc_auth_verify_data to verify
5288 the authentication directly from the authentication payload.
5289 It supports verifying both passphrase and public key based
5290 authentication. Affected file lib/silccore/silcauth.[ch].
5292 * Added `hash' field to the SilcIDListData structure. It is the
5293 hash negotiated in the SKE protocol. Affected file is
5296 * Slight redesigning of the SilcAuthPayload handling routines.
5297 Do not send SilcPKCS but SilcPublicKey as argument.
5299 * Implemented the public key authentication support to the
5300 serverconfig. The public key is loaded from the provided path
5301 and saved as authentication data to void * pointer. Thus,
5302 changed the unsigned char *auth_data to void *auth_data;
5304 * Fixed SHUTDOWN command to send the reply before the server
5305 is shutdown. :) Affected file silcd/command.c.
5307 * Fixed fatal bug in CONNECT command. The hostname was invalid
5308 memory and server crashed. Affected file silcd/command.c.
5310 * Fixed fatal bug in CLOSE command. The server_entry became
5311 invalid but was referenced later in the command. Affected file
5314 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Fixed fatal bug in failure packet handling. Server ignored
5317 the failure and thus crashed when it came.
5321 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5324 that the command may be executed only once in (about) 2 seconds.
5325 The old SILC_CF_LAG flag is same but allows command bursts up
5326 to five before limiting.
5328 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5329 server code. Various commands now includes the CF_LAG_STRICT
5330 flag to disallow any kind of miss-use of the command.
5332 * Fixed the silc_buffer_unformat to not to allocate any data
5333 if the length of the data is zero. It used to allocate the
5334 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5336 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Changed the format of AdminConnection configuration section
5339 in the server. Added username of the admin to the format.
5340 Affected files silcd/serverconfig.[ch].
5342 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5343 to return admin configuration data by host, username and/or
5346 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Implemented WHOWAS command to the server. Added the functions:
5350 silc_server_command_whowas_parse,
5351 silc_server_command_whowas_send_reply,
5352 silc_server_command_whowas_from_client and
5353 silc_server_command_whowas_from_server
5355 * Added <Client ID> argument to the WHOWAS command reply. Updated
5356 the protocol specs accordingly.
5358 * Implemented WHOWAS command and command_reply to the client
5361 Implemented the WHOWAS printing on the user interface.
5363 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Added new argument to the WHOWAS command reply, the real name.
5366 It is an optional argument. Updated the protocol specs.
5368 * Added SilcIDCacheDestructor callback that is registered when
5369 the SilcIDCache is allocated. The callback is called when
5370 an cache entry in the ID Cache expires, or is purged from the
5371 cache. Added into lib/silccore/idcache.[ch].
5373 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5374 to destruct the client entries when the cache entry expires.
5375 Other ID Cache's in server and in the client library ignores
5378 * If the ID Cache entry's `expire' field is zero then the entry
5379 never expires. Added boolean `expire' argument to the
5380 silc_idcache_add function in the lib/silccore/idcache.[ch].
5381 If it is TRUE the default expiry value is used.
5383 * Added silc_server_free_client_data_timeout that is registered
5384 when client disconnects. By default for 5 minutes we preserve
5385 the client entry for history - for WHOWAS command.
5387 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Added support to the server to enforce that commands are not
5390 executed more than once in 2 seconds. If server receives
5391 commands from client more frequently, timeout is registered
5392 to process the commands. Affected file silcd/command.c.
5393 Added new function silc_server_command_process_timeout.
5395 * Changed NICK_NOTIFY handling in client library to check that
5396 if the client's nickname was changed, so there is no need to
5397 resolve anything from the server.
5399 * Removed error printing from the WHOIS and IDENTIFY commands.
5400 If error occurs then it is ignored silently in the client library.
5401 The application, however, may map the received error to
5402 human readable error string. The application currently maps
5403 the NO_SUCH_NICKNAME error to string.
5405 * Made the command status message public to the application. Moved
5406 them from lib/silcclient/command_reply.c to
5407 lib/silcclient/command_reply.h. The application can map the
5408 received command status to the string with the
5409 silc_client_command_status_message function.
5411 * Added check to the server to check that client's ID is same
5412 as the Source ID in the packet the client sent. They must
5415 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Added dist-bzip hook to the Makefile.am to make bzip2
5418 compressed distributions.
5420 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Server now enforces the maximum length for the nickname and
5423 the channel as protocol specification dictates. 128 bytes for
5424 nickname and 256 bytes for channel name.
5426 * Moved the WHOIS printing to the application. The client libary
5427 does not print out the WHOIS information anymore, the application
5428 must do it. Renamed silc_client_command_reply_whois_print to
5429 the silc_client_command_reply_whois_save.
5431 The client's idle time is also sent to the application now, and
5432 the idle is shown on screen.
5434 * Added silc_client_command_reply_identify_save to save the
5435 received IDENTIFY entries.
5437 * Do not check for channel private keys in message sending and
5438 reception if the channel does not have the PRIVKEY mode set.
5439 Affected file lib/silclient/client_channel.c.
5441 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5444 just surfaced after chaning the JOIN procedure.
5446 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Added silc_client_get_clients_by_list to get client entries
5449 from Client ID list, that is returned for example by JOIN
5450 and USERS command replies. The application should use this
5451 function for example when JOIN command reply is received to
5452 resolve the clients already on the channel (library does not
5453 do that anymore as USERS command reply is not used in the JOIN
5454 procedure anymore). Affected files lib/silcclient/silcapi.h and
5455 lib/silcclient/idlist.c.
5457 * JOIN command reply and USERS command reply returns now SilcBuffer
5458 pointers instead of unsigned char pointers when returning
5459 the client list and mode list.
5461 * Added <Client ID> argument to the JOIN command reply, mainly
5462 for the server to identify for which client the command was
5463 originally sent. Updated protocol specs accordingly.
5465 * Added SilcDlist private_key pointer to the SilcChannelEntry
5466 in the client to support the channel private keys. Affected
5467 file is lib/silcclient/idlist.h.
5469 * Added SilcChannelPrivateKey argument to the function
5470 silc_client_send_channel_message so that application can choose
5471 to use specific private ke if it wants to. If it is not provided,
5472 the normal channel key is used, unless private keys are set.
5473 In this case the first (key that was added first) is used
5474 as the encryption key.
5476 * Implemented the support for channel private key handling.
5477 Implemented the following functions:
5479 silc_client_add_channel_private_key,
5480 silc_client_del_channel_private_keys,
5481 silc_client_del_channel_private_key,
5482 silc_client_list_channel_private_keys and
5483 silc_client_free_channel_private_keys
5485 Affected file lib/silcclient/client_channel.c.
5487 * Added the support for the private keys in the channel message
5488 sending and encryption and in the message reception and
5489 decryption. Affected funtions are
5490 silc_client_send_channel_message and silc_client_channel_message.
5492 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Added SKE's key verify callback to the client library's
5495 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5497 * Removed the statement that server (or router) must send USERS
5498 command reply when joining to the channel so that the client
5499 knows who are on the channel. Instead, the client list and
5500 client's mode list is now sent in the JOIN command reply to the
5501 client who joined channel. This is better solution.
5503 * Added function silc_server_get_users_on_channel and function
5504 silc_server_save_users_on_channel to the silcd/server.[ch].
5506 * Removed function silc_server_command_send_users from the
5509 * Do not show topic on the client library anymore. The topic is
5510 sent in the command reply notify to the application and the
5511 application must show the topic now.
5513 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added client searching by nickname hash into the IDENTIFY and
5516 WHOIS commands in the server as they were clearly missing from
5517 them. Affected file is silcd/command.c.
5519 * Fixed a bug in private message receiving in the client library.
5520 The remote ID was freed and it wasn't supposed, now it is
5523 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Minor fix to the channel payload; allocate the data area, as it
5526 needs to be of specific length.
5528 * If the key agreement port is zero then the operating
5529 system will define the bound port. Affected files are
5530 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5532 * Added new function silc_channel_payload_decrypt into the file
5533 lib/silccore/silcchannel.[ch].
5535 * Moved the channel message etc, check from silc_packet_decrypt
5536 to applications. The library calls now a generic
5537 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5538 when the packet is either normal or special. This was done to
5539 allow more wide range of checking that was not allowed when
5540 the code was in library. Now applications can do virtually any
5541 checks to the packet and return to the library the decision how
5542 the packet should be processed. Affected files are
5543 lib/silccore/silcpacket.[ch].
5545 Added silc_server_packet_decrypt_check to the server and
5546 silc_client_packet_decrypt_check to the client library.
5548 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5549 to send with specified source and destination information.
5551 * Channel message delivery between routers was broken after the
5552 channel key distribution was fixed earlier. The channel key
5553 was used be to distributed to other routers as well which is not
5554 allowed by the protocol. Now this is fixed and channel keys
5555 really are cell specific and the channel message delivery between
5556 routers comply with the protocol specification.
5558 * Fixed various commands in server to check also the global list
5559 for the channel entry and not just the local list. The affected
5560 file silcd/command.c.
5562 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Added assert()s to buffer formatting and unformatting routines
5565 to assert (if --enable-debug) when error occurs. Affected
5566 file: lib/silcutil/silcbuffmt.c.
5568 * Changed to auto-reconnect to check whether the remote host is
5569 router and register the re-connect timeout if it is. It used
5570 to check that whether we are normal server, but router must do
5571 auto-reconnect with another router as well. Affected file
5574 * Removed the [<key len>] option from CMODE command as the cipher
5575 name decides the key length, nowadays. See the defined ciphers
5576 from the protocol specification.
5578 * Added [<hmac>] option to the CMODE command to define the HMAC
5579 for the channel. Added SILC_CMODE_HMAC channel mode.
5581 * Added [<hmac>] option for the JOIN command so that user can
5582 select which HMAC is used to compute the MACs of the channel
5585 * Added Hmac field to the Channel Message Payload. The integrity
5586 of plaintext channel messages are now protected by computing
5587 MAC of the message and attaching the MAC to the payload. The
5588 MAC is encrypted. Now, it is clear that this causes some
5589 overhead to the size of the packet but rationale for this is that
5590 now the receiver can verify whether the channel message decrypted
5591 correctly and also when private keys are set for the channel the
5592 receiver can decrypt the packet with several keys and check from
5593 the MAC which key decrypted the message correctly.
5595 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5596 lib/silccrypt/silccipher.[ch].
5598 * Added silc_hash_len to return the digest length into the
5599 lib/silcrypt/silchash.[ch].
5601 * Rewrote parts of Silc Channel Payload interface in the
5602 lib/silccore/silcchannel.[ch]. The encode function now also
5603 encrypts the packet and parse function decrypts it.
5605 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Fixed a minor formatting bug in the SKE's key material processing.
5608 It actually might have processed the keys wrong way resulting
5611 * Redefined the mandatory HMAC algorithms and added new algorithms.
5612 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5613 and hmac-md5 truncated to 96 bits. The mandatory is now
5614 hmac-sha1-96. Rest are optional (including the one that used
5615 to be mandatory). Rationale for this is that the truncated HMAC
5616 length is sufficient from security point of view and can actually
5617 make the attack against the HMAC harder. Also, the truncated
5618 HMAC causes less overhead to the packets. See the RFC2104 for
5621 * Added new [hmac] configuration section. The SKE used to use
5622 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5623 is of course wrong. The official names that must be proposed in
5624 the SKE are the ones defined in the protocol specification
5625 (hmac-sha1-96 for example). The user can configure any hmac
5626 using any hash function configured in the [hash] section. At
5627 least, the mandatory must be configured.
5629 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5631 * Added HMAC list to the SKE proposal list. It has now both
5632 hash algorithm list and HMAC list. This makes the protocol
5633 incompatible with previous versions. The SKE now seems to work
5634 the way it is supposed to work, for the first time actually.
5636 * Defined plain Hash algorithms to the protocol specification.
5639 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Implemented support for key agreement packets into the server.
5642 Added functions silc_server_key_agreement and
5643 silc_server_send_key_agreement. Other than these functions,
5644 server has nothing to do with this packet.
5646 * Added support for private message key packets into the server.
5647 Added functions silc_server_private_message_key and
5648 silc_server_send_private_message_key.
5652 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5653 called in the protocol's final callback instead in the END
5654 protocol state. This makes a little more sense and in the same
5655 time in client we can use the same protocol routines for normal
5656 key exchange and to key agreement packet handling as well.
5658 * Added to both client's and server's KE protocol context the
5659 SilcSKEKeyMaterial pointer to save the key material. We will
5660 bring the key material to the protocol's final callback by doing
5661 this. The final callback must free the key material.
5663 * Added SKE's packet_send callback into client's KE protocol
5664 context so that the caller can choose what packet sending function
5665 is used. This way we can use different packet sending when
5666 doing normal SKE when doing key agreement packet handling (in
5667 the key agreement packet handling we do not want to encrypt
5670 * Implemented the responder side of the key agreement routines
5671 in the client. The client can now bind to specified port and
5672 accept incoming key negotiation. The key material is passed
5673 to the application after the protocol is over.
5675 * Implemented the processing of incoming Key Agreement packet
5676 in the client. Added function silc_client_key_agreement to
5679 * Implemented the intiator side of the key agreement routines
5680 in the client. The client can now initiate key agreement with
5681 another remote client. The key material is passed to the
5682 application after the protocol is over.
5684 * Created client_keyagr.c to include all the key agreement
5687 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5688 SILC_TASK_CALLBACK except that it is not static.
5690 * Created client_notify.c and moved the Notify packet handling
5691 from the client.[ch] into that file.
5693 * Created client_prvmsg.c and moved all private message and
5694 private message key routines from the client.[ch] into that file.
5696 * Create client_channel.c and moved all channel message and
5697 channel private key routines from the client.[ch] into that file.
5699 * Changed silc_client_get_client_by_id_resolve to resolve with
5700 WHOIS command instead of IDENTIFY command, in the file
5701 lib/silclient/idlist.c.
5703 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Implemented the SKE's responder side to the Client library.
5707 * When FAILURE is received to the protocol do not trust it
5708 blindly. Register a timeout to wait whether the remote closes
5709 the connection as it should do it, only after that process the
5710 actual failure. This was changed to both client and server.
5712 * Added client_internal.h to include some of the structures
5713 there instead of client.h in lib/silcclient/.
5715 * Added function silc_task_unregister_by_callback to unregister
5716 timeouts by the callback function.
5718 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5720 * Some "Incomplete WHOIS info" errors has been appearing on the
5721 log files. Took away the entry->userinfo check from WHOIS
5722 reply sending. The entry->userinfo is now " " if client did not
5723 provide one. I thought this was fixed earlier but something
5724 is wrong still. Let's see if the error still appears.
5726 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Fixed a minor bug in the login when the channel key is
5729 re-generated in the server. It used to generate the key in
5730 wrong order and thus caused problems in the channel traffic.
5732 * Fixed a minor bug in channel key distsribution after
5733 KICK command. The key was not sent to the router even though
5736 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Added silc_ske_process_key_material_data as generic routine
5739 to process any key material as the SILC protocol dictates. The
5740 function is used by the actual SKE library but can be used by
5741 applications as well. This relates to the private message keys
5742 and the channel private keys since they must be processed the
5743 same way the normal SILC session keys. The protocol dictates
5744 this. Affected files: lib/silcske/silcske.[ch].
5746 Added also silc_ske_free_key_material to free the
5747 SilcSKEKeyMaterial structure.
5749 * Defined silc_cipher_set_key function to set the key for
5750 cipher without using the object's method function. The affected
5751 files: lib/silccrypt/silccipher.[ch].
5753 * Implemented silc silc_client_add_private_message_key,
5754 silc_client_add_private_message_key_ske,
5755 silc_client_del_private_message_key,
5756 silc_client_list_private_message_keys and
5757 silc_client_free_private_message_keys functions in the
5760 Added functions silc_client_send_private_message_key to send
5761 the Private Message Key payload and silc_client_private_message_key
5762 to handle incoming Private Message Key payload.
5764 * Added Cipher field to the Private Message Key payload to set
5765 the cipher to be used. If ignored, the default cipher defined
5766 in the SILC protocol (aes-256-cbc) is used.
5768 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Removed lib/silcclient/ops.h file.
5772 Redefined parts of the SILC Client Library API. Created new
5773 file silcapi.h that deprecates the ops.h file and defines the
5774 published Client Library API. Defined also private message key
5775 API and channel private key API into the file.
5777 This is the file that the application must include from the
5778 SILC Client Library. Other files need not be included by
5779 the application anymore.
5781 * Added new key_agreement client operation callback and also
5782 defined the Key Agreement library API for the application.
5784 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5787 is used by clients to request key negotiation between another
5788 client in the SILC network. If the negotiation is started it
5789 is performed using the SKE protocol. The result of the
5790 negotiation, the secret key material, can be used for example
5791 as private message key.
5793 Implemented the Key Agreement payload into the files
5794 lib/silccore/silauth.[ch].
5796 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Redefined ciphers for the SILC protocol. Added some new ciphers
5799 and defined the key lengths for the algorithms. Changed the
5800 code accordingly. The default key length is now 256 bits.
5802 * Fixed SKE key distribution function silc_ske_process_key_material
5803 when the key length is more than 128 bits. The default key
5804 length in SILC is now 256 bits.
5806 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5807 to indicate unsupported algorithm.
5809 * Renamed rijndael.c to aes.c and all functions as well.
5811 * Fixed a long standing channel key setting bug in client library.
5812 Weird that it has never surfaced before.
5814 * Fixed bug in channel deletion. If the entire channel is removed
5815 then it must also delete the references of the channel entry
5816 from the client's channel list as the client's channel entry and
5817 the channel's client entry share same memory.
5819 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Implemented CONNECT and SHUTDOWN commands in the client.
5823 * Implemented CLOSE command to the client.
5825 * Added the function silc_idlist_find_server_by_name into the
5826 files silcd/idlist.[ch].
5828 Added the function silc_idlist_find_server_by_conn into the
5829 files silcd/idlist.[ch].
5831 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * DIE command was renamed to SHUTDOWN. Updated the both code
5836 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5837 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5839 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5842 * Added function silc_server_create_connection function to create
5843 connection to remote router. My server implementation actually
5844 does not allow router to connect to normal server (it expects
5845 that normal server always initiates the connection to the router)
5846 so the CONNECT command is only good for connecting to another
5849 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5852 or some other client was kicked from the channel.
5854 Implemented the handling of the notify type to both client
5857 Implemented silc_server_send_notify_kicked to send the KICKED
5858 notify. It is used to send it to the server's primary router.
5860 * Implemented the KICK command into server and client.
5862 * Added `query' argument to the silc_idlist_get_client function
5863 to indicate whether to query the client from server or not if
5866 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5867 to indicate that the client is not channel founder.
5871 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Removed the rng context from SilcPacketContext structure and
5874 changed that the packet routine uses the Global RNG API.
5876 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added support for quit message that client can "leave" on the
5879 channel when it quits the SILC. It is ditributed inside the
5880 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5882 Added silc_server_free_client_data that will take the
5883 signoff message as argument.
5885 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5887 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Updated parts of the protocol specification to keep it up
5892 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5895 payloads in one packet.
5897 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5898 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5899 use now the new List flag.
5901 * Also deprecated the following packet types: REPLACE_ID,
5902 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5904 * Added list support for Notify packet in server.
5906 * Added silc_server_send_notify_channel_change to send the
5907 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5908 the silc_server_send_replace_id.
5910 * Added silc_server_send_notify_nick_change to send the
5911 NICK_CHANGE notify type. Deprecates the function
5912 silc_server_send_replace_id.
5914 * Added silc_server_send_notify_join to send the JOIN notify type.
5915 Deprecates the function silc_server_send_new_channel_user.
5917 * Added silc_server_send_notify_leave to send LEAVE notify type.
5918 Deprecates the function silc_server_send_remove_channel_user.
5920 * Added silc_server_send_notify_cmode and
5921 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5922 types. Deprecates the silc_server_send_set_mode function.
5924 * Added SERVER_SIGNOFF notify type to indicate that server has
5925 quit. This means that all clients on the channel from that
5926 server will drop. This can be also used when netsplit happens.
5928 Deprecated REMOVE_ID packet type since it is not needed anymore
5931 Added silc_server_send_notify_server_signoff to send the
5932 SERVER_SIGNOFF notify type. Deprecates the function
5933 silc_server_send_remove_id.
5935 Added also silc_server_send_notify_signoff to send the
5936 SIGNOFF notify type.
5938 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5939 SILC protocol from this day on. Changed the protocol
5940 specification as well.
5942 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5943 notify type. It is used between routers to notify about
5944 topic changes on a channel.
5946 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5949 * Partly updated the protocol specification to comply with the
5950 changes now made. It is still though a bit outdated.
5952 * The JOIN notify type now takes one extra argument <Channel ID>.
5953 The packet used to be destined to the channel but now the
5954 JOIN type may be sent as list thus it is impossible to
5955 destine it to any specific channel. By adding this argument
5956 it is again possible.
5958 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Added CREDITS file. The CHANGES and CREDITS file will appear
5961 in the distribution as well.
5963 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5966 types in the server's silcd/packet_receive.c.
5968 * Implemented CMODE and CUMODE to work in router environment.
5970 * Fixed minor encoding and decoding buglet from the
5971 lib/silccore/silcmode.c.
5973 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5976 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5978 * Changed all SilcConfigServer* and silc_config_server* to
5979 SilcServerConfig* and silc_server_config*, respectively.
5982 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Associated the ID (client or server ID) to the Authentication
5985 Payload to avoid any possibility of forging. Updated the
5986 protocol specification and the code accordingly.
5988 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * The RSA key length is now save to the RsaKey context in the
5991 key generation process in lib/silccrypt/rsa.c. The key length
5992 is now used to figure out the maximum size of the block allowed
5993 to be encrypted/signed.
5995 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5996 is equivalent to the silc_mp_mp2bin but does not allocate any
5999 * Changed silc_mp_mp2bin API to take length argument. If it is
6000 non-zero then the buffer is allocated that large. If zero, then
6001 the size is approximated using silc_mp_sizeinbase, which however
6004 * Created Global RNG API which is global RNG that application can
6005 initialize. After initializing, any routine anywhere in the
6006 code (including library) can use RNG without allocating a new
6007 RNG object. This was done to allow this sort of use of the
6008 RNG in code that has no chance to allocate RNG object. All
6009 applications currently allocate this and many routines in the
6010 library use this. Affected file lib/silccrypt/silcrng.[ch].
6012 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6013 it to use the Global RNG API.
6015 * Defined Authentication Payload into protocol specification that
6016 is used during SILC session to authenticate entities. It is
6017 used for example by client to authenticate itself to the server
6018 to obtain server operator privileges.
6020 Implemented this payload into the lib/silccore/silcauth.[ch].
6021 Implemented also routines for public key based authentication
6022 as the new protocol specification dictates.
6024 Moved definitions of different authentication methods from
6025 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6027 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6028 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6029 silc_pkcs_verify_with_hash functions into the file
6030 lib/silccrypt/silcpkcs.[ch].
6032 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * The client entry's userinfo pointer must be always valid.
6035 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6036 will fail since it requires the userinfo. Now, the userinfo
6037 is allocated as "" if actual userinfo does not exist. Actually,
6038 it must exist and it is totally Ok to drop client connections
6039 that does not announce the userinfo. However, we will make
6040 this workaround for now.
6042 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6043 to return the remote port by socket.
6045 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6048 SILC_SERVER_PENDING_EXEC and added an new macro
6049 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6050 data or when error occurs while processing the pending command.
6052 Added new argument `destructor' into silc_server_command_pending
6053 and to the SilcServerCommandPending object. This destructor is
6054 now called after calling the pending callback or if error occurs
6055 immediately. If error occurs the actual pending callback won't
6056 be called at all - only the destructor. The destructor may be
6057 NULL if destructor is not needed.
6059 All this applies for client library code as well. Similar
6060 changes were made there as well for the pending commands.
6062 In the client, the application must now allocate the
6063 SilcClientCommandContext with the silc_client_command_alloc
6066 * Added reference counter to the SilcServerCommandContext. Added
6067 function silc_server_command_alloc and silc_server_command_dup
6070 Same type of functions added to the client library for the same
6073 * Removed the cmd_ident from IDListData away since it is now
6074 global for all connections. It is the command identifier used
6075 in command sending and with pending commands. The affected file
6078 * Added reference counter to the SilcSocketConnection objecet to
6079 indicate the usage count of the object. The object won't be
6080 freed untill the reference counter hits zero. Currently only
6081 server uses this, and client ignores it. The client must be
6082 set to use this too later. The affected files are
6083 lib/silccore/silcsockconn.[ch]. Added also the function
6084 silc_socket_dup to increase the reference counter.
6086 This was mainly added because it is possible that the socket
6087 is removed underneath of pending command or other async
6088 operation. Now it won't be free'd and proper DISCONNECTING
6089 flags, etc. can be set to avoid sending data to connection that
6090 is not valid anymore.
6092 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6093 the connection. After that it sets SILC_SET_DISCONNECTED.
6094 It is, however, possible that the socket data is not still freed.
6095 The silc_server_packet_process now checks that data is not
6096 read or written to connection that is DISCONNECTED. The socket
6097 get's freed when the reference counter hits zero.
6099 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Changed the client operation API: channel_message operation's
6102 `sender' is now the client entry of the sender, not the nickname
6103 and the `channel' is the channel entry, not the channel name.
6105 In the private_message operation the `sender' is now also the
6106 client entry of the sender not the nickname.
6108 Affected file is lib/silcclient/ops.h and all applications
6109 using the client operations.
6111 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Moved the calling of ops->connect() from connect_to_server_final
6114 into receive_new_id functin since that is the point when the
6115 client is actually allowed to send traffic to network. The
6116 affected file is lib/silcclient/client.c.
6118 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6121 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6122 (if needs broadcasting) instead of broadcasting the packets one
6123 by one which would make a burst in the network traffic.
6125 * Added `broadcast' argument to the functions in silcd/server.[ch]
6126 silc_server_create_new_channel[_with_id] to indicate whether
6127 to send New Channel packet to primary router.
6129 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Added new function into the silcd/server.[ch] files:
6132 silc_server_create_new_channel_with_id to create new channel with
6133 already existing Channel ID.
6135 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6136 lib/silccore/silcpacket.h. This packet is used t send list of
6137 Set Mode payloads inside one packet. Server uses this to set
6138 the modes for the channels and clients on those channels, that it
6139 announced to the router when it connected to it. The protocol
6140 specification has been updated accordingly.
6142 * The silc_server_new_channel did not handle the packet coming
6143 from normal server as it normally does not send that. However,
6144 when it announces its channels it does send it. Implemented
6145 the support for that.
6147 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6148 into the file lib/silccore/id.h.
6150 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Fixed memory leaks in the functions silc_idlist_del_client,
6153 silc_idlist_del_channel and silc_idlist_del_server in the file
6154 silcd/idlist.c. All of those leaked like a sieve.
6156 * Fixed some small memory leaks in the client's function
6157 silc_client_notify_by_server.
6159 * Added functions into silcd/server.c: silc_server_announce_clients,
6160 silc_server_announce_channels and silc_server_announce_server.
6161 These functions are used by normal and router server to announce
6162 to its primary router about clients, channels and servers (when
6163 router) that we own. This is done after we've connected to the
6166 These functions effectively implements the following packet types:
6167 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6168 and SILC_PACKET_NEW_ID_LIST.
6170 * Added new functions into the silcd/packet_receive.[ch]:
6171 silc_server_new_id_list, silc_server_new_channel_list and
6172 silc_server_new_channel_user_list to handle the incoming
6173 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6175 * Added support of changing Channel ID in the function
6176 silc_server_replace_id. If the server that announces a channel
6177 to the router already exists in the router (with same name but
6178 with different Channel ID), router is responsible to send
6179 Replace ID packet to the server and force the server to change
6180 the Channel ID to the one router has.
6182 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6183 client that the Channel ID has been changed by the router. The
6184 normal server sends this to the client. Client must start using
6185 the new Channel ID as the channel's ID.
6187 Implemented handling of this new type into lib/silcclient/client.c
6188 into the function silc_client_notify_by_server.
6190 * Added new function silc_idlist_replace_channel_id into the files
6191 silcd/idlist.[ch] to replace the Channel ID.
6193 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Call silc_server_command_identify_check always when processing
6196 the IDENTIFY command in silcd/command.c
6198 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6201 send keepalive packets. The packet can be sent by clients,
6202 servers and routers.
6204 Added function silc_socket_set_heartbeat into the file
6205 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6206 If not set, the heartbeat is not performed. The actual
6207 heartbeat is implemented in the low level socket connection
6208 library. However, application is responsible of actually
6211 Added silc_server_send_heartbeat to send the actual heartbeat
6212 packet into silcd/packet_send.[ch]. Server now performs
6213 keepalive with all connections.
6215 * Added silc_task_get_first function into lib/silcutil/silctask.c
6216 to return the timeout task with shortest timeout. There was a bug
6217 in task unregistration that caused problems. TODO has been
6218 updated to include that task system must be rewritten.
6220 * The client library will now resolve the client information when
6221 receiving JOIN notify from server for client that we know but
6222 have incomplete information.
6224 * Rewrote parts of silc_server_remove_from_channels and
6225 silc_server_remove_from_one_channel as they did not remove the
6226 channel in some circumstances even though they should've.
6228 * Encryption problem encountered in server:
6230 The LEAVE command used to send the Channel Key packet to the
6231 router immediately after generating it. However, the code
6232 had earlier sent Remove Channel user packet but not immediately,
6233 ie. it was put to queue. The order of packets in the router
6234 was that Channel Key packet was first and Remove Channel User
6235 packet was second, even though they were encrypted in the
6236 reverse order. For this reason, MAC check failed. Now, this
6237 is fixed by not sending the Channel Key packet immediately but
6238 putting it to queue. However, this is more fundamental problem:
6239 packets that are in queue should actually not be encrypted
6240 because packets that are sent immediately gets encrypted
6241 actually with wrong IV (and thus MAC check fails). So, packets
6242 that are in queue should be encrypted when they are sent to
6243 the wire and not when they put to the queue.
6245 However, the problem is that the current system has not been
6246 designed to work that way. Instead, the packet is encrypted
6247 as soon as possible and left to the queue. The queue is then
6248 just purged into wire. There won't be any fixes for this
6249 any time soon. So, the current semantic for packet sending
6252 o If you send packet to remote host and do not force the send
6253 (the packet will be in queue) then all subsequent packets to the
6254 same remote host must also be put to the queue. Only after the
6255 queue has been purged is it safe again to force the packet
6258 o If you send all packets immediately then it safe to send
6259 any of subsequent packets through the queue, however, after
6260 the first packet is put to queue then any subsequent packets
6261 must also be put to the queue.
6263 Follow these rules and everything works fine.
6265 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Added new function silc_server_remove_clients_by_server to
6268 remove all client entries from ID list when the server connection
6269 is lost. In this case it is also important to invalidate all
6270 client entires as they hold the invalid server entry. This
6271 fixes fatal bug when server has lost connection and will reconnect
6274 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6276 * Made some sanity checks to silc_server_daemonise like to check
6277 whether the requested user and group actually exists.
6279 * Added sanity check to SKE's silc_ske_responder_finish to check
6280 that the public and private key actually is valid.
6282 * Invalidate the client's nickname when receiving Replace ID
6283 packet and the Client ID is being replaced. This means that the
6284 server will query the nickname if someone needs it (client)
6287 * Sort the ID Cache in client library when the ID Cache data
6288 has changed (needs sorting).
6290 * Do not allow for SILC client to create several connections to
6291 several servers. The client does not support windows right now
6292 and generating multiple connections causes weird behaviour.
6294 Irssi-silc client does support windows and can handle several
6295 connections without problems, see: www.irssi.org and SILC plugin.
6297 * Fixed some places where client was added to the IDList. The
6298 rule of thumb is following (in order to get everything right):
6299 If the client is directly connected local client then the
6300 `connection' argument must be set and `router' argument must be
6301 NULL to silc_idlist_add_client function. If the client is not
6302 directly connected client then the `router' argument must
6303 bet set and the `connection' argument must be NULL to the
6304 silc_idlist_add_client function.
6306 * The funtion silc_server_packet_send_local_channel actually did
6307 not check whether the client was locally connected or not. It
6308 does that now. Fixed a bug related to LEAVE command.
6310 * Fixed Remove Channel User payload parsing bug in server's
6311 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6313 * The server's silc_server_save_channel_key now checks also the
6314 global ID list for the channel as it might not be in the local
6315 list. Fixed a bug related to LEAVE command.
6317 * Is this the end of the [<unknown>] buglet that has been lurking
6318 around for a long time? A little for loop fix in server's
6319 silc_server_command_whois_parse that is used by both IDENTIFY
6320 and WHOIS command. At least, this was a clear bug and a cause
6321 of one type of [<unknown>] buglet.
6323 * WHOIS and IDENTIFY commands call the function
6324 silc_server_command_[whois/identify]_check function even if
6325 we are not router server.
6327 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added --with-gmp configuration option. If set the GMP
6330 is always compiled in the SILC source tree. If not set then
6331 it is checked whether the system has the GMP3 installed. If
6332 it has then the GMP won't be compiled (the system's headers
6333 and library is used), if it doesn't have it then the GMP is
6334 compiled in the SILC source tree.
6336 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Changed RSA private exponent generation to what PKCS #1
6339 suggests. We try to find the smallest possible d by doing
6340 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6341 not security fix but optimization.
6343 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Added new config entry [Identity] to fork the server and run
6346 it as specific user and group. A patch from Bostik.
6348 * Imported Dotconf configuration library into lib/dotconf.
6349 This will be used to create the SILC configuration files later.
6350 It will appear in the distsribution after this commit.
6352 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * A big code auditing weekend happening. Auditing code for
6355 obvious mistakes, bugs and errors. Also, removing any code
6358 Removed files for being obsolete:
6360 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6361 inline in the file lib/silcutil/silcbuffer.h)
6363 o lib/silcutil/silcbufutil.c (the header has inline versions)
6365 Changed code to fix possible error conditions:
6367 o The buffer formatting routines now check that the destination
6368 buffer really has enough space to add the data. This applies for
6369 both buffer formatting and unformatting
6370 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6371 unformatting was changed to accomodate following rules:
6372 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6373 sent to the function while XXX_*STRING will not allocate or copy
6374 the data into the buffer. Instead it sets the pointer from the
6375 buffer into the pointer sent as argument (XXX_*STRING used to
6376 require that the pointer must be allocated already). This change
6377 makes this whole thing a bit more consistent and more optimized
6378 (note that the data returned in the unformatting with XXX_*STRING
6379 must not be freed now). The routines return now -1 on error.
6381 o Tried to find all code that use buffer_format and buffer_unformat
6382 and added return value checking to prevent formatting and
6383 especially unformatting errors and possible subsequent fatal
6386 o Changed ske->x and ske->KEY to mallocated pointers in
6387 lib/silcske/silcske.h. Fixed possible data and memory leak.
6389 o Added return value checking to all *_parse* functions. Fixed
6390 many memory leaks as well.
6392 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6393 so that buffer overflows would not happen. All code now also
6394 checks the return value as it can fail.
6396 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6398 * Added reconnection support to server if the normal server looses
6399 its connection to the router (for example if router is rebooted).
6400 The server performs normal reconnection strategy implemented
6401 to the server. Affected file silcd/server.c.
6403 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Added new packet type SILC_PACKET_SET_MODE that is used to
6406 distribute the information about changed modes (for clients,
6407 channels and clients channel modes) to all routers in the
6408 network. Updated the protocol specification accordingly.
6410 Added functions into silcd/packet_send.c and
6411 silcd/packet_receive.c: silc_server_send_set_mode,
6412 silc_server_set_mode.
6414 Added new files silcmode.[ch] into lib/silccore that implements
6415 the encoding and decoding of Set Mode Payload. Added new type
6416 SilcSetModePayload. Moved the definitions of different modes
6417 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6419 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Oops, a little mistake in server's connection authentication
6422 protocol. The protocol is not ended with FAILURE but with
6423 SUCCESS if the authentication is Ok. :) Affected file is
6426 * Implemented NICK_CHANGE notify handling in server in the file
6427 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6428 the local clients on the channel. After the changing nickname
6429 in router environment snhould work and the [<unknown>] nickname
6430 should appear no more.
6432 The silc_server_replace_id function that receives the Replace ID
6433 payload now sends the NICK_CHANGE notify type also in the file
6434 silcd/packet_receive.c
6436 * Changed WHOIS and IDENTIFY command to support the maximum amount
6437 of arguments defined in protocol specs (3328 arguments). This
6438 fixed a bug that caused problems when there were more than three
6441 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6443 * Added extra parameter, command identifier, to the
6444 silc_client_send_command so that explicit command identifier
6447 Changed that ID list routines uses specific command identifier
6448 when sending WHOIS/IDENTIFY requests to the server so that they
6449 can be identified when the reply comes back.
6451 Affected files lib/silcclient/command.[ch],
6452 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6454 * Added `sender' argument to silc_server_packet_send_to_channel
6455 to indicaet the sender who originally sent the packet to us
6456 that we are now re-sending. Ignored if NULL. Affected file
6457 silcd/packet_send.[ch].
6459 * Added some server statistics support in silcd/server_internal.h
6460 SilcServerStatistics structure and around the server code. Also
6461 send some nice statistics information when client is connecting
6464 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * Fixed channel ID decoding in server's JOIN command reply in
6467 silcd/command_reply.c
6469 * Fixed braodcasting of replace ID payload to not to send it if
6470 we are standalone server in silcd/packet_receive.c.
6472 * Fixed all channel message sending routines to not to send
6473 packets to clients that has router set, since they are routed
6474 separately in the same function earlier. Affects file
6475 silcd/packet_send.c and all channel packet sending functions.
6477 * In USERS reply, res_argv[i] are not allocated, the table
6478 is allocated. Thus changed that free the table, not its
6481 * In server's whois_check and identify_check if the client is
6482 locally connected do not send any WHOIS commands - they are not
6485 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Fixed some minor bugs in client when sending WHOIS command. The
6488 arguments was in wrong order.
6490 * Removed statis function add_to_channel from server in
6491 silcd/command.c that was previously used with the joining but
6494 * Tested USERS command in router environment successfully with two
6495 routers, two servers and two clients.
6497 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6499 * Reorganized the USERS command and command reply in client library
6500 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6501 When the command is given by user we register a pending command
6502 callback that will reprocess the command after the reply has been
6503 received from the server. When reprocessing the packet we then
6504 display the information. Thus, the USERS information is displayed
6505 now in the command callback instead of in the command reply
6506 callback. The processing of the command is same as previously
6507 when server has sent the command reply in the JOINing process.
6509 * Added to USERS command in silcd/command_reply.c to join the client,
6510 we didn't use to know about, to the channel after we've created
6511 a client entry for it. Also, for clienet we did know already still
6512 check whether it is on the channel or not and add it if not.
6514 * Removed silc_server_command_join_notify as the function and its
6517 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Changed the client's pending command handling to the same as the
6520 server's pending command handling. It is also now possible to
6521 execute command reply functions from other command reply
6522 function as the function callbacks for commands and command
6523 replies are one and same. The pending commands are not static
6524 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6525 in client connection context. Thus, pending commands are server
6526 connection specific as it is convenient.
6528 Changed the function silc_client_command_pending and
6529 silc_client_command_pending_del and added new function
6530 silc_client_command_pending_check. Removed the
6531 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6534 * Added cmd_ident, current command identifier, to the client
6535 connection context in lib/silcclient/client.h to keep track on
6536 command identifiers used in command sending. Client's command reply
6537 function handling now supports the mandatory command identifiers.
6539 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6540 funtions in client to fully support pending command callbacks.
6542 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6543 as one of the arguments to the application in the command reply
6546 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6547 before first releasing SILC but came back. Now it is removed again
6548 and should come back nomore. The FORWARDED flag was used only
6549 by the JOINing procedure by forwarding the command packet to router.
6550 Now, the JOINing procedure has been changed to more generic (due
6551 to various router environment issues) and FORWARDED is not needed
6552 anymore for anything. The protocol specification is yet to be
6555 Now, removed silc_server_packet_forward from server and the flag
6556 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6558 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6560 * Renamed NAMES command to USERS command. The NAMES was named that
6561 due to historical reasons. Now it is renamed. Also, rewrote
6562 parts of the USERS command. The nickname list is not sent anymore
6563 by the server. Only Client ID and mode lists are sent in the USERS
6564 command. Changed this also to the protocol specification.
6566 The client now resolves the names and stuff after it receives
6567 the USERS list from the server when joining to the channel.
6569 * WHOIS and IDENTIFY commands has been changed to support multiple
6570 Client ID's per command. One can now search for multiple users
6571 in the network by sending only one WHOIS or IDENTIFY command.
6572 Changed the code and the protocol specifications.
6574 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6575 uses silc_server_command_whois_parse to parse the request. */
6577 * If normal server, do not parse the WHOIS and IDENTIFY requests
6578 before sending it to the router. Saves some time.
6580 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6582 * Fixed JOIN command on client library. Wrong number of arguments
6583 used to crash the client.
6585 * Added silc_server_channel_has_global function to check whether
6586 channel has global users or not.
6588 * Added silc_server_channel_has_local function to check whether channel
6589 has locally connected clients on the channel.
6591 * The silc_server_remove_from_one_channel now checks whether the
6592 channel has global users or not after given client was removed from
6593 the channel. It also checks whether the channel has local clients
6594 on the channel anymore. If it does not have then the channel entry
6595 is removed as it is not needed anymore.
6597 * The silc_server_notify now checks on JOIN notify whether the joining
6598 client is one of locally connected or global. If it is global then
6599 the channel has now global users on the channel and that is marked
6600 to the channel entry. Also, it now saves the global client to
6601 global list who is joining and JOINs it to the channel. This is
6602 for normal server, that is.
6604 Changed silc_server_send_notify_on_channel,
6605 silc_server_packet_relay_to_channel and
6606 silc_server_packet_send_to_channel check if we are normal server
6607 and client has router set (ie. global client) do not send the
6608 message to that client, as it is already routed to our router.
6610 * Implemented LEAVE notify type handling in silc_server_notify
6613 * Tested LEAVE command in router environment successfully. Tested
6614 with two routers, two servers and two clients.
6618 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6620 * Implemented SIGNOFF notify type handling in silc_server_notify
6623 * silc_server_remove_id now removes the client entry from all channels
6624 it has joined and thusly sends SIGNOFF notify type.
6626 * Rewrote the NAMES list generation in server by removing two excess
6627 loops. The lists are created now inside one loop.
6629 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * silc_server_remove_channel_user checks now also global list
6632 for channel and client.
6634 * silc_server_new_channel_user checks now both local and global
6635 list for channel and client. Fixed a bug in client id decoding.
6636 Used to decode wrong buffer.
6638 * silc_server_channel_message checks now both local and global
6639 list for channel entry.
6641 * Tested channel joining (hence JOIN) in router environment
6642 successfully. Tested with two routers, two servers and two
6645 * Tested channel message sending in router environment successfully.
6647 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Added silc_server_save_channel_key into server.[ch] to save the
6650 received channel key in Channel Key payload processing. It is
6651 also used in JOIN command reply handling.
6653 Equivalent function silc_client_save_channel_key added into
6654 client.[ch] into client library.
6656 * Changed JOIN command reply to send information whether the channel
6657 was created or not (is existing already) and the channel key
6658 payload. Changed protocol specs accordingly.
6660 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6661 the request was sent by ID and not by nickname. Crashed on
6664 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6667 now correctly save the received data.
6669 * silc_server_free_sock_user_data now notifies routers in the
6670 network about entities leaving the network.
6672 At the same time implemented functions silc_server_remove_id
6673 and silc_server_send_remove_id to receive and send REMOVE_ID
6674 packets. The packet is used to notify routers in the network
6675 about leaving entities. The ID removed will become invalid in
6678 * Added function silc_idlist_del_server into server. Removes and
6679 free's server entry from ID list.
6681 * silc_server_private_message function now checks, if we are router,
6682 that the destination ID really is valid ID, naturally.
6684 * In router when NEW_ID packet is received (for new client) the
6685 hash of the Client ID is saved in the ID Cache but the
6686 client->nickname is set to NULL, instead of putting the hash
6689 IDENTIFY command now also checks that client->nickname must be
6690 valid. If it is not if will request the data from the server who
6691 owns the client. Added new function
6692 silc_server_command_identify_check.
6694 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6695 to set the command to already allocated Command Payload.
6697 * Tested private message sending in router environment with two
6698 routers, two servers and two clients. Fixed minor bugs and now
6701 * Fixed segfault from client's NAMES command. Used to crash if
6704 * Forwarded packets must not be routed even if it is not destined
6705 to the receiver. Changed server code comply with this.
6707 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Added `require_reverse_mapping' boolean value to ServerParams
6710 structure. If TRUE (not default) the server will require that
6711 the connecting host has fully qualified domain name.
6713 If the reverse mapping is not required and hostname could not be
6714 found the IP address is used as hostname.
6716 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Implemented version string checking to both client and server.
6719 The check is incomplete currently due to the abnormal version
6720 strings used in development version of SILC.
6722 * Changed all command functions in server to use the new
6725 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6727 * Changed char *data to unsigned char *data in ID Cache system to
6728 support binary data as ID Cache data. Changed code to support
6729 binary data in lib/silccore/idcache.c.
6731 * Renamed silc_server_packet_relay_command_reply to
6732 silc_server_command_reply as it is normal packet receiving
6733 function. Rewrote the function to accept command replys for
6734 servers and not only for clients.
6736 * Mark remote router always as registered server if we are connecting
6737 to it. Otherwise, commands sent by the router to us are ignored.
6739 * All ID List find routines now returns the ID Cache Entry pointer
6740 as well if requested.
6742 * WHOIS command works now in router environment, tested with two
6743 routers, two servers and two clients.
6745 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6746 in router environment (as it is almost equivalent to WHOIS) but
6747 hasn't been tested thoroughly. Added new functions:
6749 silc_server_command_identify_parse
6750 silc_server_command_identify_send_reply
6751 silc_server_command_identify_from_client
6752 silc_server_command_identify_from_server
6754 * Disabled route cache adding because adding two different ID's with
6755 same IP replaces the old cache entry thus giving wrong route.
6756 The entry->router->connection is always the fastest route anyway
6757 so route cache may not be needed. Of course, new routes maybe
6758 established after receiving the ID when the entry->router->connection
6759 might not be anymore the most optimal.
6761 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Add route cache for received ID for fast routing.
6765 * Added silc_server_packet_route to route received packet on router
6766 that is not destined to us.
6768 * Renamed silc_server_get_route to silc_server_route_get.
6770 * Added id_string and id_string_len fields into SilcServer to
6771 include encoded ServerID for fast comparing without excess
6772 encoding of the ID's.
6774 * Cleaned up WHOIS command on server side. Added following static
6777 silc_server_command_whois_parse
6778 silc_server_command_whois_check
6779 silc_server_command_whois_send_reply
6780 silc_server_command_whois_from_client
6781 silc_server_command_whois_from_server
6783 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6784 arguments in command replies. All command functions should be
6785 updated to use this macro.
6787 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Minor typo fixes on command reply handling on server.
6791 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * Added silc_server_command_add_to_channel internal routine to add
6794 the client to the channel after router has created the channel and
6795 sent command reply to the server.
6797 * Added generic silc_server_send_command to send any command from
6800 * Use static buffer with ID rendering instead of duplicating data.
6802 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Fixed a channel user mode bug when joining to a channel server gave
6805 everybody channel founder rights, oops.
6807 * We mark ourselves as the router of the incoming server connection
6808 if we are router ourselves. This way we can check in some packet
6809 sending functions whether it is locally connected server. For
6810 incoming router connections we put NULL.
6812 * For router sending packets locally means now always sending the
6813 packet cell wide; to local clients and local servers. For normal
6814 server sending packet locally means sending it to only local
6817 * Fixed the JOIN command to really work in router environment. If the
6818 channel is created it is always created by the router. Router is
6819 also responsible of making the initial joining to the channel,
6820 sending JOIN notify to the sending server and distributing
6821 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6822 does not exist server doesn't do anything else but forward the
6823 command to the router which performs everything.
6825 * Added silc_server_send_channel_key function to send the Channel Key
6828 * Added silc_server_create_channel_key to create new channel key. The
6829 channel key is now re-generated everytime someone joins or leaves
6830 a channel, as protocol dictates. Note: channel->key_len is the
6833 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6835 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6836 packet_receive.[ch] to separate packet sending and receiving
6837 routines. The server.[ch] now includes everything else including
6838 actual packet processing (writing and reading data) and other
6841 Renamed silc_server_private_message_send_internal to
6842 silc_server_send_private_message. The routine is still though
6843 used only to relay private messages as server does not send
6844 private messages itself.
6846 Renamed silc_server_new_channel to silc_server_create_new_channel
6847 and added new function sicl_server_new_channel that handles the
6848 incoming New Channel packet. Added also new sending function
6849 silc_server_send_new_channel to send New Channel Payload.
6851 * Added new function silc_server_notify to process incoming notify
6852 packet to the server/router. Server may then relay the notify
6853 to clients if needed.
6855 * Added new function silc_server_new_channel_user to process incoming
6856 New Channel User packet. Router will redistribute the packet and
6857 send JOIN notify to its local clients and locally connected servers
6858 if needed. Normal server will send JOIN notify to its local client
6859 on same channel when received this packet. Added also corresponding
6860 sending function silc_server_send_new_channel_user to sent the
6863 * Added boolean route argument to send_notif_to_channel and
6864 packet_send_to_channel functions to attempt to route the packet
6865 if it is TRUE and send only locally if it is FALSE.
6867 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * silc_server_replace_id now broadcasts the received replace ID
6870 packet if it is not broadcast packet already. The router must
6871 broadcast to inform other routers about changed ID.
6873 * Added backpointer to server's router into SilcServer context in
6874 silcd/server_internal.h.
6876 * Fixed silc_server_packet_broadcast to send correct broadcast
6879 * The channel key is now distributed to the local client as soon
6880 as it is received from the router (in router environment) so that
6881 no other packet may be sent for the channel until client has
6884 * silc_server_remove_channel_user now broadcasts the received
6885 Remove Channel User packet if it is not broadcast packet already.
6886 The router must broadcast to inform other routers about removed
6889 * Added users field into SilcPacketContext that is a reference count
6890 of the context. One can increase the reference count by calling
6891 silc_packet_context_dup which is now changed to just increase the
6892 reference count instead of duplicating the data. The reference
6893 count is decresed by calling silc_packet_context_free that will
6894 free the data after the reference count hits zero.
6896 For now on the packet context and everything allocated into it
6897 (including the raw packet from network) must be freed by calling
6898 the new silc_packet_context_free function. Added also new function
6899 silc_packet_context_alloc that must be used now to allocate the
6900 context. This also means that if a routine is asynchronous from
6901 silc_[client/server]_packet_parse_type the packet context must
6902 be duplicated by calling silc_packet_context_dup. Otherwise it
6903 gets free'd after silc_[client/server]_packet_parse_type returns.
6904 Also, one must remember that if packet is duplicated then its
6905 reference count must be decresed by calling the free function as
6906 many times as it was duplicated.
6908 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6909 from both client and server.
6911 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Made joining to a channel working in router environment.
6915 * Cleaned up JOIN command on server side and create function
6916 silc_server_command_join_channel internal routine to make the
6919 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Changed silc_command_pending list to SilcDList. Also, added
6922 `ident' field to SilcServerCommandPending structure to identify
6923 the reply and to call correct callback.
6925 Added silc_server_command_pending_check function to replace the
6926 corresnponding macro. The silc_command_pending list is not
6929 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6930 to set identifier to previously allocated Command Payload. It
6931 is used to set identifier for command when resending Command
6934 * Added silc_command_payload_encode_payload to encode Command
6935 Payload buffer from SilcCommandPayload structure.
6937 * Added silc_argument_payload_encode_payload to encode Argument
6938 payload buffer from SilcArgumentPayload structure.
6940 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Changed WHOIS command to support router connection on server side.
6943 The whois request is always sent to router unless the server is
6944 standalone server. After server has received the reply from the
6945 router will it send the reply to the client.
6947 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6948 broadcast received broadcast packet. The function is used only
6949 by router. The broadcast packet is always sent to the router's
6952 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6953 render given ID to printable string, for log files for example.
6955 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Made basic router to router connections working. At least they
6958 can now connect to each other but nothing really works the way
6959 they are supposed - yet.
6961 * Added new initiator token to RouterConnection configuration
6962 file in silcd/serverconfig.[ch]. It is used to tell whether we
6963 are the initiator to the remote router or whether we'll expect
6964 the other end to connect.
6966 * Moved registering of listener task to silc_server_init, hence
6967 the server starts listenning as soon as it is run, even if it
6968 does not have connections to other routers. Let's see how well
6971 * Changed default connection retry timeouts for more suitable in
6974 * Removed cipher and such arguments from silc_idlist_add_client
6975 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6976 Added new function silc_idlist_add_data to add the keys and stuff
6979 * Added SilcIDListData structure and added it to SilcClientEntry
6980 and SilcServerEntry as their first field in the structure. This
6981 way we can explicitly cast the ID entries to the SilcIDListData
6982 structure and get common data for the entries. In past, we had
6983 to first check what type of connection it is and then cast it to
6984 correct ID entry type. Now, we can directly cast the opaque
6985 pointer to the SilcIDListData (no matter what ID entry it actually
6986 is) and get the data needed.
6988 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6990 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6991 in some circumstances even if threre were timeout tasks, though not
6992 IO tasks, but tasks anyway. Now fixed.
6994 * Defined SilcServerConnection structure to hold connection specific
6995 stuff about directly connected servers and routers. The definition
6996 is currently in silcd/server_internal.h. I thought about having
6997 a bit more important role fro this struct but for now it is used
6998 only when connecting to other server (or router actually).
7000 * Added connecting retry support in server when connecting to
7001 router(s). The retry feature implement exponential backoff
7002 algorithm. Also, added SilcServerParams structure to hold default
7003 parameters for server. For now, it include these retry settings
7004 and are hard coded. After server is moded to be as Silc Server
7005 Library this structure will be more important.
7007 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7009 * Changed client librarys channel->clients table to SilcList and
7010 changed code accordingly.
7012 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7014 * Changed client's channel table to SilcList and changed code
7015 accordingly. Also changed SilcChannelClientEntry to include back-
7016 pointer to the channel so that client entry can use that structure
7017 as list as well and we have fast cross-reference to the channel.
7018 This change dramatically decreased the complexity of channel
7019 handling with client entry and vice versa (removed one extra
7020 loop when searching for channel entry from many functions).
7022 * Changed server->sim from table to SilcDList and changed code
7025 * NAMES command can now be used from user interface. It will show
7026 the user list on the channel, neatly.
7028 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7029 Code now saves realname of the user if it becomes available.
7031 * Renamed configure.in to configure.in.pre and made ./prepare
7032 script to automatically add correct version string to
7033 configure.in which it creates from configure.in.pre.
7035 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7037 * NAMES command reply now shows users mode with the nickname when
7040 * Moved silc_client_ch[u]mode[_char] functions from
7041 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7042 place sucks, they are utility functions and should be in some
7045 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7047 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7050 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * Added TRQ (efficient deque and list library) into lib/trq. This is
7055 a very good list library that is currently used in the SILC. Defined
7056 SilcList API over the library because I didn't like the API very
7057 much. See lib/trq/silclist.h for the API and examples of how to
7058 use the API. Fixed various places in the code to use the new
7059 SilcList API. The SilcList is meant for lists that has a structure
7060 already defined as a list. It is not suitable to add just some
7061 context to the list (in TRQ, the context is the list actually).
7063 So, I defined SilcDList that can be used for the purpose where
7064 predefined list structure does not exit. This can be used as
7065 such list. Now some context just can be added to the SilcDList.
7066 Currently this list is not used in the SILC just yet, though there
7067 are a lot places where this can replace dynamically allocated
7068 tables and I will fix these places, later, to use SilcDList.
7069 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7070 and use TRQ internally).
7072 Also fixed some annoying warning messages that the original TRQ
7073 code generated. Also minor changes to TRQ's Makefile.in.
7075 * Added support for querying by Client ID to both WHOIS and
7076 IDENTIFY commands into server, as required by the protocol.
7078 * Removed method function pointers from SilcBuffer structure. They
7079 weren't used to anything and just increased the context size for
7080 no good reason. This change also made silc_buffer_alloc and
7081 silc_buffer_free functions inline functions.
7083 * Disabled command flooding detection support until it's fixed so
7084 that it accepts commands in but does not execute them more than once
7087 * Added silc_net_localhost(), to return local hostname, into
7088 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7089 that must be initialized before calling silc_client_init.
7091 * Added new function: silc_server_send_notify_on_channels to send
7092 notify messages to all channels client has joined. It is assured
7093 that the message is sent only once per client.
7095 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7096 lib/silcutil/silcutil.[ch] as silc_format function. The new
7097 function is generic and is used by server as well, not only by
7098 the logging routines.
7100 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7101 the provided version string was not acceptable. Added new function:
7102 silc_ske_check_version into lib/silcske/silcske.h. The function
7103 must be implemented by the application (client or server) and it
7104 does not reside in the SKE library. The function checks the version
7105 string remote end sent.
7107 * Added back pointers (to opaque context and to SilcSocketConnection)
7108 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7110 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7111 duplicate packet context structure.
7113 * Changed `notify' client operation to send same arguments as client
7114 receives from server except for ID's. ID's are mapped to correct
7115 ID entry and that is returned. Also, if channel entry is not sent
7116 by server but the notify is for channel the channel entry is sent
7117 to application (otherwise application doesn't know that it is for
7118 channel (library gets it from packet's Destination ID)).
7120 * Added silc_client_remove_from_channels into client library to
7121 remove a client from all channels it has joined to. Used when
7122 received SIGNOFF notify from server. Added also new function
7123 silc_client_replace_from_channels to replace old ID entry with
7124 new ID entry on all channels. Used when received NICK_CHANGE
7127 * Fixed ID Cache list handling in silc_idlist_get_client in
7128 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7129 to get (or query) client by ID.
7131 * Updated TODO list.
7133 * Added connection authentication status message defined by the
7134 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7135 support for these into the code in client and server side.
7137 * Added generic function silc_client_send_command to send any command
7138 with variable argument list. Application should use this function
7139 to send commands if the command functions provided by the library
7140 does not suite for the application's user interface needs.
7142 * Added new `failure' client operation. Application is notified about
7143 received failure packet if client is executing a protocol. In this
7144 case the protocol's execution has failed.
7146 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7147 is required by the protocol.
7149 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7150 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7153 * Added status flag to SilcSKE object to indicate realtime status
7154 of the SKE protocol.
7156 * Application receives now exactly same command reply arguments as
7157 the library receives from server. However, if ID is received the
7158 corresponding ID entry is returned to the application (eg. Client
7159 ID is mapped to correct SilcClientEntry entry and that is returned).
7160 Changed command_reply client operation due to this change.
7162 * Changed all ID's in commands and in command replys as ID Payloads.
7163 Change affected both client and server side codes.
7165 All ID's sent in SILC network (with execption of ID's in SILC
7166 Packet header) are sent in ID Payload to support variable length
7169 * Server now notifies nick changes and notifies all clients on
7170 the channels about the new nickname (about the new Client ID,
7173 * Implemented CMODE command to change channel modes. Supports all
7174 channel modes defined by the protocol specs except ban and invite
7175 lists. (Also, private channel key mode is supported but support for
7176 setting private channel key in client is missing, thus, this mode
7177 has no effect on client side (except that server requires that the
7178 client uses private channel key and normal channel traffic does not
7181 Also, invite mode works per se, but INVITE command does not work
7182 yet correctly, so you can set channel as invite only channel but
7183 inviting clients to the channel does not work (it is yet to be
7184 thought what's the best way to do it).
7186 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7187 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7188 Implemented CUMODE command to change user's mode on the channel.
7189 Supports all modes defined by the protocol specs.
7191 * Added NAMES command reply to return users modes on the channel.
7193 * Removed unnecessary and slow ciphers from lib/silccrypt.
7195 * Set SO_KEEPALIVE option to connection sockets by default.
7197 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7199 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7200 redefined the Notify Payload into protocol specs.
7202 * Added silc_id_payload_parse_id to get ID directly from raw
7205 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7208 accept searching by Client ID as well.
7210 * Added support for LEAVE and SIGNOFF notify types in client library.
7212 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7213 to parse ID Payload from raw data.
7215 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7217 * Added flags parameter into silc_ske_assemble_security_properties
7218 function in lib/silcske/silcske.[ch].
7220 * Changed notify client operation to fit better for notify messages
7221 sent by server. The notify payload received from server is now
7222 passed to the application (after parsing it to SilcNotifyPayload).
7223 It is application's responsibility to retrieve the arguments
7224 from the payload and show the message the way it wants. The message
7225 sent by server is implementation specific.
7227 * Changed public keys to comply with the protocol specification.
7228 Old public keys are not supported anymore and are not compatible.
7230 * Removed nickname from Channel Payload as the latest draft removed
7231 it. The client must resolve the nickname from the NAMES command
7232 reply received when it joined the channel.
7234 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7236 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7238 * Fixed some errors in protocol specification drafts.
7240 * Created lib/silccore/silcnotify.c to implement Notify Payload
7241 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7242 generic payloads described by protocol specifications. The file
7243 includes implementations for ID Payload and Argument Payload.
7245 * Changed Command Payload implementation to use the new Argument
7246 Payload. Changed command_xxxx_payload to command_payload_xxxx
7247 to comply with SILC coding conventions.
7249 * Added suppport for Argument Payload handling in Notify Payload
7250 implementation as protocol requires it. Added the new support
7251 into server and client lib as well.
7253 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Added support for multiple nicknames on same channel. [n] is
7256 added locally to the nickname if there are more than one same
7257 nicknames on the channel.
7259 * Server now sends all nicknames that matched WHOIS request.
7260 Client also shows the list received from server.
7262 * Added TOPIC command to client side. User can now set and show
7263 current topic on channel.
7265 * Added MOTD command to client and server. Also, server sends the
7266 motd when client connects to the server.
7268 * Changed version strings to comply ISO 8601.
7270 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Fixed protocol error handling in client library. It should now
7273 cope even if the SKE fails for some reason.
7275 * Made new protocol specification drafts for submitting to IETF.
7277 * Implemented TOPIC command to server in silcd/command.c.
7279 * Added two new notify types into lib/silccore/silcnotify.h:
7280 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7281 notify nickname change and topic setting/change on a channel.
7283 * API change of command_reply operation in client library. The
7284 application gets now the status type received from server as well.
7286 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7288 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7290 * Cras fixed and optimized the packet handling even further and
7291 it should work now. Minor change to the prototype of function
7292 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7294 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7296 * Added new function into lib/silcutil/silcschedule.[ch]:
7297 silc_schedule_with_fd to select() a specified fd. The function
7298 returns after timeout expires or data arrives or goes. The
7299 function is used by packet routines to wait that all data is
7300 received from network.
7302 * Fixed data reading from network in lib/silccore/silcpacket.c.
7303 The code now assures that all data is read from the fd and then
7304 continues packet processing. This was a bug fix since the code
7305 used to drop some data in some circumstances.
7307 * Added new function into lib/silcclient/client.[ch]:
7308 silc_client_start_key_exchange to start key exchange after
7309 connection has been established to server. The code internally
7310 now uses this funtion but its main purpose was to provide it
7311 for applications that perform their own connecting. After
7312 application has created a connection it merely calls this
7313 function to start the key exchange between client and server.
7314 The library takes care of everything else after that.
7316 Updated also lib/silcclient/README to explain the usage of
7319 * Do not send to application information that connection has
7320 been established. Application gets notified it by connect
7323 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7325 * Applied cras's patch to add silc_schedule_one function. The
7326 function runs scheduler once and returns.
7328 * Fixed the scheduler after cras messed it up. The timeout
7329 handling works now as it's supposed to work.
7331 * Added into lib/silccore/ silcnotify.h to include notify
7332 message types support. Changed silc_server_send_notify*
7333 functions, in server.[ch], to support those new notify types.
7334 Added the support for the notify types into client library,
7335 as well. Added new notify client operation into ops.h in
7338 * Changed silc_server_packet_send_to_channel to send normal
7339 packets instead of just channel message packets. The function
7340 is now used to send the notify packets to channels. It is not
7341 used to send channel message packets anymore, as server never
7344 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7345 va_arg()s as it seems to require it nowadays. I guess, if SILC
7346 is compiled with older va_arg() the new code should work anyway.
7348 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Splitted core library. Core library (lib/silccore) includes
7351 now only SILC protocol specific core (and common) components.
7352 Created new utility library (lib/silcutil) that includes more
7353 generic purpose stuff. The stuff for util library was taken
7354 from the old core library. This was minor and easy split.
7356 * Created SILC Client Library (lib/silcclient) that includes
7357 implementation of the SILC client without user interface. This
7358 was major move from silc/ directory. The code has been changed
7359 so that it is transparent towards the user interface. The
7360 silc/ directory includes now the same user interface as before
7361 and it uses the new client library. Read lib/silcclient/README.
7362 Basicly, the client library performs everything else related
7363 to SILC except user interface handling. Also, configuration
7364 files are considered to be part of user interface and library
7365 does not handle them.
7367 This change also changed a lot of structures, function naming etc.
7368 Most important change was that SilcClientWindow object was
7369 renamed to SilcClientConnection in the client library. Created
7370 also new file lib/silcclient/ops.h. Also added new files
7371 silc/local_command.[ch] and silc/client_ops.[ch].
7373 All these changes were made to make it easier for user interface
7374 designers to create what ever user interface for the SILC client
7377 It is also expected that the server will be moved to lib
7378 directory as well and SILC Server Library will be created;
7379 sometimes in the future.
7381 * Removed Local commands from lib/silccore/silccommand.h as
7382 they are application specific and new client library does not
7383 handle any of those anymore.
7385 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7386 old client implementation in silc/.
7388 * Added support for callback functions in SILC_LOG_* macros.
7389 Application can now set its own callbacks that will be called
7390 instead of using the default functions that will always print
7391 the debug messages to stderr (or stdout). Also, debugging can
7392 now be disabled by setting silc_debug to FALSE and re-enabled by
7393 setting it to TRUE. Note, that logging will still work even
7394 if debugging is disabled.
7396 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7397 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7398 silc_log_reset_debug_callbacks.
7400 * To enable debugging in silc client one must give now -d
7401 option on command line.
7403 * Changed silc_schedule_init to automatically allocate task queues
7404 if they are not allocated before calling it.
7406 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Added GMP 3.1 into math library.
7410 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7413 a channel in SILC network. The packet is used by servers and
7414 routers to notify other routers that user has left a channel.
7415 This little feature was missing until now. Added the feature
7416 to protocol specification as well.
7418 Added functions: silc_server_send_remove_channel_user and
7419 silc_server_remove_channel_user into server.[ch].
7421 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7422 lib/silccore/silcpacket.h. However, they are not implemented
7425 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7427 * Fixed joining to a channel and sending channel messages
7428 between server and router. The channel message sending should
7429 now work inside a cell.
7431 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Fixed the private message sending between server and router.
7434 The private message sending should now work inside a cell.
7436 * Added silc_server_replace_id into server.[ch] to replace
7437 existing ID in the SILC network.
7439 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7440 and silc_idlist_replace_server_id into idlist.[ch] in server.
7442 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Fixed the server to server connections. Server can again now
7445 connect to router. Router to router connections probably does
7448 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7450 * Added dynamic protocol registering support. Now protocols can
7451 registered and unregistered on the fly. Patch by cras.
7453 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7455 * Added lib/contrib directory to hold routines that some platforms
7456 don't have but are needed by SILC.
7458 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7459 into lin/contrib to provide getopt() and getopt_long() for
7460 those who don't have it.
7462 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7464 * Added AWAY command to client. When away message is set and
7465 client receives a private message packet the client automatically
7466 replies to the sender with the away message.
7468 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7469 bug seemed to be the cause of recent problems when compiling
7472 * Added version detection support to SKE protocol specification
7473 and added the new changes to the SKE implementation as well.
7474 There were other minor changes in the SKE protocol as well.
7476 Many changes in lib/silcske/silcske.[ch] and in
7477 lib/silcske/payload.[ch].
7479 * Added ^U functionality, clear input line. Patch from cras.
7481 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Mainly small bugfixes on core library. Fixed some debugging
7484 logging and buffer overflow in silclog.c.
7486 * Updated config.sub and config.guess on the distribution tree.
7488 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Added command lagging support in server. Client may execute
7491 commands now only once in two seconds.
7493 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Optimized packet reception. MAC computation and checking is now
7496 also more optimized. A lot previously duplicated code is now
7497 used as generic by both client and server.
7499 * Fixed key pair generation in clientutil.c
7501 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7503 * Added into lib/silccore/silcbufutil.[ch] new function;
7504 silc_buffer_realloc.
7506 * Moved generic packet sending/encryption functions to
7507 lib/silccore/silcpacket.[ch] from client and server. Some
7508 rewriting of the functions.
7510 * Moved all generic packet reception/decryption functions to
7511 lib/silccore/silcpacket.[ch] from client and server. The
7512 packet processing is now much cleaner in both client and server.
7513 These were major changes in both client and server.
7515 * Created many common functions in server to do packet sending.
7516 Previously code were duplicated a lot, this has been removed
7519 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Rewrote major parts of the ID cache system. Don't know
7522 whether it is better now or not but at least the API is more
7525 * Major rewrite on ID cache stuff on client because of the ID
7526 cache API changes. Added idlist.c to client.
7528 * Also major rewrite on ID cache stuff on server as well.
7529 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7530 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7531 in hand, instead they are all put into the ID cache system now.
7532 All server_idlist_* routines uses ID cache now instead of
7533 traversing its own lists (those lists does not exist anymore).
7534 SilcIDList though still exists. Also, SilcXXXEntry's are
7537 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7539 * Finally made the SKE implementation compliant to the protocol
7540 specification. All mp integers are now binary encoded as
7541 opposed being HEX encoded.
7543 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7546 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7547 functions: silc_[encode/decode]_pem. Also added function
7548 silc_encode_pem_file to PEM encode with newlines ('\n') for
7551 * SILC public keys are now encoded either PEM or binary. Same
7552 option is for private keys as well. By default private keys
7553 are binary encoded and public keys PEM encoded. Silly HEX
7554 encoding were removed.
7556 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7557 function to create fingerprints.
7559 * Fixed a bug in SHA1; does not change the original data anymore.
7561 * Partly implemented INFO command on client and server side.
7562 Fixed CLEAR command. Changes to SERVER command; show current
7563 server(s) when giving command without arguments. Added
7564 VERSION command to client.
7566 * Added check to server that unregistered connections cannot
7567 execute commands (unless it is specificly allowed).
7569 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7571 * Fixed screen refresh.
7573 * Fixed channel joining bug from client. On some circumstances
7574 client tried to join to a channel it had already joined.
7576 * Added public key verification process into client's protocol.c.
7577 The client now verifies the public key from user and saves
7578 it into ~./silc/serverkeys/ directory.
7580 Added into: clientutil.[ch]: silc_client_verify_server_key.
7582 * Changed SKE protocol's silc_ske_initiator_finish function
7583 to accept callback function that verifies the received public
7584 key. Removed old silc_ske_verify_public_key function.
7586 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7588 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7589 silc_pkcs_private_key[_data]_set.
7591 * Made the password and public authentication more cleaner in
7592 server's protocol.c.
7594 * Removed historic and obsolete protocol `channel_auth' from
7595 both client and server.
7597 * Removed wrong way of sending command status messages from
7598 server to client in server's command.c. The old way violated
7599 protocol specification.
7601 Changes to silccore/silccommand.[ch]: removed
7602 silc_command_encode_status_payload -> not needed anymore,
7603 changed silc_command_encode_payload_va to accept extra
7604 argument on variable argument list. The argument type must
7605 now be provided to the function. Also, added new function:
7606 silc_command_encode_reply_payload_va which is same as
7607 normal command_encode_payload_va except command status type
7608 is provided as extra argument.
7610 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Added ~./silc directory handling. The directory includes the
7613 public and private keys for the client.
7615 Added silc_client_check_silc_dir, silc_client_create_identifier
7616 and silc_client_load_keys.
7618 * Implemented SILC protocol compliant public key. Added public
7619 and private key saving to and loading from files.
7621 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7622 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7623 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7624 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7625 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7627 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7628 silc_pkcs_load_[public/private]_key.
7630 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Added silc_server_get_route (route.[ch]) to get connection
7633 data for the fastest route for given ID.
7635 * Implemented INVITE command on client and server. The command
7636 were re-defined in the SILC Protocol Specification and the
7637 implementation now complies with the specification.
7639 * Implemented PING command on client and server.
7641 * Implemented NAMES command on client and server. The server side
7642 supports currently only normal server not router server yet.
7643 Some changes to NAMES definition in SILC protocol specification.
7645 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Implemented LEAVE command on client and server.
7649 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7650 again. This change was made to the protocol as well. Server
7651 should not violate the protocol specification anymore.
7653 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7656 was tested. SOCKS4 was not but should work anyway.
